"For more than a decade, neuroscientist Grgoire Courtine has been flying every few months from his lab at the Swiss Federal Institute of Technology in Lausanne to another lab in Beijing, China, where he conducts research on monkeys with the aim of treating spinal-cord injuries.

The commute is exhausting on occasion he has even flown to Beijing, done experiments, and returned the same night. But it is worth it, says Courtine, because working with monkeys in China is less burdened by regulation than it is in Europe and the United States"

I personally know researchers who have to take similar measures to be able to do their research.

When we are happy as a society to slaughter billions of animals every year for food (usually keeping them in appalling conditions beforehand) I don't understand how we can justify the restrictions we put on scientists.

"The problem I see with this is that they implant monkey before paralysis and can use machine learning to build a model of the monkey's unique representation for walking. Then they paralyze and show the monkey's can adapt to only using their interface in 5 days. There's no way the mapping from neural activity to stimulation is generalizable..." [1]

I struggled with this while in graduate school studying neuroscience. Fortunately, I was studying crustaceans so there were not too many ethical issues. But there was rodent and monkey research happening in the school. I choose to return to my first profession - software. I assume that I'll be long dead before there are ethical issues with experimenting on AI.

Animal research is something that we as a society are going to struggle with for many years into the future. I would like to be able to argue that it is for the greater good of the planet, but I don't think that I could put up a good argument that we are being proper stewards of the planet.

This is absolutely fantastic and its a great step in the right direction but we are still years if not decades away from being able to circumvent spinal lesions in humans.

One of the major problems with human spinal lesions is the loss of control of the trunk of the body (ie the core). Humans have dozens of muscle groups that control balance and posture through minute movements. Without fine grain control over these muscles balance is going to be extremely difficult.

We have seen many such interfaces in recent years, but as I understand these techniques they all suffer the same problem. The body eventually coats the electrodes in a non-conductive layer, essentially scar tissue, and the whole thing grinds to a halt in a matter of weeks. Until that practical limitation is surmounted, it seems very wrong to treat animals in such a manner. Watching the paralyzed monkey (also the rat) struggle in obvious agony as the commentators cheered was not fun. This was not the sort of thing I had expected to see on a program clearly aimed at a general audience. This was the very dark side of animal testing.

I saw this story on a canadian news show a couple days ago, a show that regularly does spots on human exploration of Mars. The stories are similar. The headline feel-good story is about the shiny new mars habitat or spacesuit someone is testing, but they haven;t figured out how to actually get it to mars. The result is the false impression that the dreamed future, colonizing Mars and curing paralysis, is closer than is true.

Do people really want recommendations?

I personally want to just have an RSS reader that gives me the articles from the sites I freaking asked for. Not what some service thinks I'll like. Google, Pocket, and other sites are already doing a great job of thumbing through what I read and trying to sneak in their "suggestions": that's the kind of invasive data-combing that I want to avoid.

Sorry I'm not interested in a Feed Reader that tries to give me suggestions. I like to follow the stuff I like to follow. I do the footwork of finding quality sources by myself.

Maybe I'm not most RSS users in that regard, I'm not sure, haven't done the market research.

It feels to me that suggested sources leads to promoted sources leads to paid content.

For work (writer) I go through dozens of feeds every day.

About 90% of what I see is irrelevant, but I need to see it to filter out the relevant data. I'd pay a decent amount for a service that can tailor itself and deliver relevant results without much manual intervention. InoReader and some other RSS readers have decent filtering, but it's all manual.

So this excited me, but without a way to import my existing feeds it's largely useless to me.

I'm confused. It looks like this won't work unless you use the stream API, which is (apparently) not open source / self hosted.

The only reasons I can think of to host my own RSS reader are to prevent third party profiling, editorial transparency, and future proofing against the provider shutting down or evolving the service in a way that I don't like. This provides none of those advantages.

Am I missing something?

Does anyone know an RSS feed reader with these features?

1) Deduplication

2) Grouping of articles on the same topic. For example, grouping all articles on Angela Merkel's latest Brexit comments, so I can easily choose one and ignore the rest.

Grouping would make me an order of magnitude more efficient when reading RSS. I'd happily pay $100 for that feature.


3) Efficiently and automatically manage broken feeds: Automatically retry (over X hours or days), automatically look for a replacement feed, and then let me know which feeds need my attention.

asib 12 minutes ago 1 reply      
Going off on a bit of a tangent, it's interesting to think about how 100 odd years ago if your heart stopped, you were declared dead. Then we got defibrillators and CPR, etc. and suddenly if your heart stopped you could still be resuscitated.

Further, nowadays, if you have a heart attack and no one makes an effort to resuscitate you, and there's someone who knows how to nearby, most people would argue that that person has forgone a moral obligation.

This is one of the arguments made for cryonics[0], in two ways. If in the future it's possible that we'll be able to revive a cryopreserved body, then you can't really consider someone dead if they're cryopreserved within a certain timeframe after their heart stops (just as today you can't consider someone dead within the ~5 minutes after their heart stops, because of CPR, etc). What's more, the people of the future will have a moral obligation to revive cryopreserved bodies, because not doing so would be the equivalent of not attempting CPR on someone who just had a heart attack. This is the response given when someone asks why anyone in the future would be bothered to go through the hassle of reviving cryopreserved bodies.

Food for thought.

It's a scary and fascinating look at the so-called "death determination" industry that addresses one of our society's least-asked questions: in an era of unprecedented medical skill and technology, who draws the line between life and death, why do they draw it there, and how much are they getting paid?

As medicine gets better and we develop a better understanding of how our bodies work this question will only get more difficult. At some point it will be possible to program your cells to repair any damage to your body including regenerating limbs or organs. And when you can do that, taking someone who is "dead", hooking them up to the "autodoc"[1] and having it repair the damage and restart them, then the only question might be how many short term memories did you lose? And if you can download those some how then even a partly decomposed body could be the source material for reconstructing the original, not a clone per se because parts of the original are re-used but certainly a full retrofit. Then a lot of built in human assumptions get really challenged.

Is there a medical person here who can help me out with this? Take these excerpts from the article:

"He suggested using the newly invented stethoscope to listen for a heartbeat if the doctor didnt hear anything for two minutes, they could be safely buried."

"An electrical engineer from Brooklyn, New York, had been investigating why people die after theyve been electrocuted and wondered if the right voltage might also jolt them back to life."

"Starting in the 1950s, doctors across the globe began discovering that some of their patients, who they had previously considered only comatose, in fact had no brain activity at all."

"They had discovered the beating-heart cadavers, people whose bodies were alive though their brains were dead."

"In some cases, their hearts kept beating and their organs kept functioning for a further 14 years for one cadaver, this strange afterlife lasted two decades."

Now... If the brain were dead (by my understanding of a 'dead' organ - its cells have died), wouldn't the brain start either decomposing or being absorbed by the body? If that happens, it's a pretty clear indication that the brain is truly dead. But if it doesn't happen, doesn't that mean the brain cells are still alive (just not communicating for some reason)? And in that case (living cells with a blank EEG), couldn't there be a way to jump-start their communication, as was previously discovered with hearts?

I'm sure that I'm completely ignorant of some critical factor, and look forward to your thorough discussion of it...

I can't tell if this is an error, as if it should have been "[...] patient is the correct term" or if the neurologist is trying to be funny, or make a point. IMO the writer/editor should've omitted this quote or clarified its context and overall meaning to the article.

This is surprising, and it could mean that early commenters have their voice heard more than later commenters. But it could also just mean that topics raised by early commenters end up being discussed in those threads, and commenters on both sides have their voices heard.

For example, if the first comment is roughly "I read the linked article and disagree because of A, B, and C" then someone with an opposing viewpoint would probably reply to the existing first comment instead of creating a separate comment.

This doesn't mean that the second commenter's voice isn't heardit just means it all happens under the thread created by the first commenter.

Back when I was a regular on LessWrong and it had an active community, it didn't have that problem at all, despite using a variant of the Reddit codebase. Their solution was pretty simple, just show the five most recent comments in the right hand column. People would interact with them, check out their parent comments, and threads would grow organically regardless of age. It might be tricky to scale that to larger communities though.

Makes sense, due to a self-reinforcing dynamic: early comments that are good enough to gather upvotes will stay near the top of the page, gathering more upvotes.

I suspect HN is subject to the same "first comment effect," often to the detriment of later comments that might be more deserving of the top spot.

Serious question:

Once I have been building Qt Widgets application in Python with PySide bindings. I needed to do some simple processing in several SLOTs and decided to use lambdas as an easy replacement. Kids, do not even think about attempting to do this at home, seriously.

I have run into some extremely evasive random crashes and stuff. I did not dig to the bottom of the issue, although my guess is that Python lambdas are executed in main (constructing) thread context and that causes race conditions.

My question: how do Golang's goroutines interact with native threads spawned by Qt?

Last I saw, QT's GPL/LGPL license required you to open-source the code that was statically linked to it. That wasn't much of a problem for desktop platforms, as you could just package up all of QT into its own QT.DLL (or the equivalent) and link to it dynamically. But this isn't allowed on stuff like iOS, so you were required to buy a license for those.

falcolas 10 minutes ago 0 replies      
The biggest pain for me in managing a system is handling all of the service configurations; making sure the ACLs are in place, that the configuration files are all in the right place and in the correct format.

Serverless isn't saving me any of that pain. I still have to configure ACLs for everything, web folders in S3, ensure that my backend isn't hitting any concurrency or timeout limits, ensure that all of my routes are set up properly in the API gateway, that my DB queries are properly tuned and that someone is watching that DB...

All it's really buying me is not having to write Ansible scripts, but instead I have to write CloudFormation templates. Sure, I have to think about maintenance and troubleshooting less, but when I do have to do troubleshooting, I'm for a long, frustrating day.

As easy as it is to create VMs anymore, the serverless story is nowhere near as compelling as it should be. It makes the easy things easier, and the hard things really f'ing hard.

Concrete example: I wanted to just store the contents of a github webhook post in S3, after verifying the hashed secret. Should be a simple case of wiring together the API gateway to S3, right?

First bug: You can't test an API Gateway -> S3 connection if they are both in the same region. Known issue from back in 2014.

First hurdle: You can't pass the contents of a post to an auth hook in API gateway, just a single header value. That means I can't use the API Gateway authentication hook for this purpose; github creates a HMAC hash of the post contents.

Second hurdle: Finding the proper Velocity Template Language function (and its location in Amazon's custom libraries) to escape the JSON from the webhook body so I could pass it on to a lambda function. It's '$util.escapeJavaScript($input.body)' by the way. You're welcome.

By this point, I was wishing I had just set up a t2.tiny server running flask.

* API development (like AWS's APIG)

* Support for more languages by default

* Ability for users to a custom defined language easily

* Creation of an opinionated framework / workflow for FaaS development (you don't need to do this if you don't want to...but FaaS first apps would be done better/easier this way)

* Rewriting common products (Wordpress, Ghost, Jekyll etc.) for to be served via FaaS.

Things I don't want to work on (or would prefer to not jump into):

* Storage service (S3 alternatives)

* Databases (there are so many out there...building a cloud is hard, building a database is even more so)

Who do I feel would pay for this?

* Front end & Mobile devs who don't want to complicate a backend

* Mobile devs who don't want to complicate a backend

* Enterprises maybe?

Shameful plug: Our developer site is serverless: http://developer.avalara.com/

Content is stored in our public github repo, and we use TravisCI to build Jekyll pages on commit/merge, which are uploaded and served from S3.

Interactive functionality is provided via React in the front end, and API-Gateway/ AWS Lambda in the backend.

The API Gateway/Lambda provide various proxies to our various sandbox API environments, so Developers can quickly try our APIs directly on the site.

Has anyone used the AWS API Gateway service with lambdas to set up a small backend for a web service? The next thing I'm thinking about setting up is a slush reader with a GUI, and I'm wondering how difficult it will be to pipe binary files from S3 -> Lambda -> API Gateway -> client. It looks like I'll probably need to encode the binaries to base64 on the lambda side, and will need a library for that.

I made this comment on a related thread yesterday[0]:

You don't need crypto. You just need a machine that prints out a human readable receipt that the voter can see but not alter, which then drops into a secure holding area on the machine.At the end of the day, you randomly select say 1% of all the machines and hand count all the ballots inside, making sure the counts and votes match. If they do, then you can be reasonably sure it wasn't tampered with, and if they don't match, then you can hand count all the paper ballots using the old system to verify the computer.

The main problem with digitally signing/encrypting a vote is that the public key must be known, which means that someone's vote cannot be anonymous.

I like the idea of a county/precinct/district being the entity who signs the results of a vote. This would protect the anonymity of individual voters, since results are reported on a per county basis today anyways. And if a county is suspected of voter fraud, you could always add their public key to a blacklist..

The article is very slightly more nuanced but the conceptss the title purports is DANGEROUSLY INCOMPETENT for any security expert / discussion / context.

1) idea that security is something you check off and be done with is dangerously wrong. Security must be continuous, must be updated, reviewed, etc.

2) idea that you can "encrypt" [secure] your entire life is ludacris and leads to many dangerous security misconceptions. You don't even have control of your entire life, let alone ability to secure it. Most the data on you is owned by others and not even available to you to secure. The world is not private or secure. Everyone needs to know and think about this when they are tweeting, sexting, talking shit about future president and then being surprised when SS comes to investigate.

3) idea that security is either on/off, a binary, that you can be secure or not. Is False and leads to extremely poor security choices, over/under securing. Nothing is secure. There is not such thing as SECURE. Things lie on a gradient of security from easy to break to impractically difficult. Things on the impractical to break technically end are still broken due to social engineering, externalities (power consumption of cpu), poor practices surrounding item, etc. Security is making the effort required to get an item greater than the value of getting the item.

Something I've seen over and over again is that Tor users tend to have a poor understanding of what Tor protects and doesn't protect. The original Tor paper said that Tor (or any technology of its kind) can't protect you against someone who can see both sides of the connection -- including just their timing. Sometimes, some adversaries can see both sides of a person's connection. As The Grugq and others have documented, Tor users like Eldo Kim and Jeremy Hammond were caught by law enforcement because someone was monitoring the home and university networks from which they connected to Tor and saw that they used Tor at exactly the same time or times as the suspects did. (In Hammond's case, recurrently, confirming law enforcement's hypothesis about his identity; in Kim's case, only once, but apparently he was the only person at the university who used Tor at that specific time.)

As law enforcement has actually identified Tor users in these cases, I think people need to understand that Tor is not magic and it protects certain things and not other things. In fact, I helped to make a chart about this a few years ago:


This chart was meant to show why using HTTPS is important when you use Tor, but it also points to other possible attacks (including an end-to-end timing correlation attack, represented in the chart by NSA observing the connection at two different places on the network) because many people in the picture know something about what the user is doing.

I've been a fan of Tor for many years, but I think we have to do a lot better at communicating about its limitations.

I worked with MVC before, but eventually I found that DDD (Domain Driven Design) is what I'm looking for. Domain Driven Design is more like a set of rules of how to apply the existing design partners (eg: repository, factory and aggregation) and building blocks (eg: layering architecture) to design your business models and keep the integrity, invariance between data. Moreover, it lets you easily define the boundary between your services for Microservice architecture.

MVC was originally designed as a pattern for desktop UIs. It has a single controller and a single model, not the MVC style that Rails popularized with one controller class and one model class for every kind of data. In classic MVC, Views query the Model for relevant data. The Controller handles user actions and uses that to update the Model, then asks the View to redraw (preferably in some smart efficient manner). This is unidirectional data flow pur sang and it comes from 1988. How is React+Redux any different from this?

I agree with the author that components are the true innovation of React, because it encourages reusable building blocks by default. Contrast with classic desktop and mobile UI toolkits which, while often also using or encouraging MVC, do not require the developer to not subdivide their own codebase into reusable widgets. Instead, they allow composing an entire screen (window, page, form, whatever) from the built-in widgets. Making a reusable widget is possible but extra work and therefore not done. In React, it's the only way to go.

This is awesome about React, but it has nothing to do with data flow architecture, which is what MVC is.

The mistake webdevelopers made for years was trying to shoehorn DHH's backend remix of MVC into the frontend, throwing away decades of UI building architecture knowledge. I'm happy the Facebook people rediscovered MVC and I'm even happy they gave it a new name (Flux) because MVC frankly has gotten way too many definitions.

But saying that Flux/Redux killed MVC is like saying Clojure killed Lisp.

Quarrelsome 11 hours ago 1 reply      
Its the same pattern. The whole point of MVC isn't the damn precise implementation its about separating out the concerns of the view, the services/data and a thing or some things that control and/or glue it all together.

The point is to not munge all these things into one monolithic horrible grim mess. As long as you are separating the concerns of showing something to a user, allowing them to control it and backing it all with potentially remote service who cares what the pattern is precisely called? Its still flavours of this original desire that we named MVC.

All these presenter/unidirectional patterns are _just_ the underlying desire of MVC and the only reason that people seem to talk about how "MVC isn't right" or "is dead" is because they've followed MVC like dogma instead of just a guideline of separating your presentation, control and service logic. I had exactly this debate back when everyone was talking about MVP as if it was some revolutionary new thing. Its not, its all the same thing and GOF was never supposed to be a template for software but a way of talking about specific ideas that architects could then riff on. They're chords, not one specific tune that you _must_ play in a very specific way.

> As more and more developers start to see the advantages of components and unidirectional architectures, the focus will be on building better tools and libraries that go down that path.

"Unidirectional architecture" is a weird name for what is a fairly standard abstraction. Every front-end at the top level is:

 f(my_entire_state, some_event) -> my_entire_state'
In the end all you need are well defined state transitions, an event bus and a main loop to connect the two. Persist the sequence of events for undo/redo, audit, debugging ... and the current state for caching or having durability between sessions. Push side-effects to the boundaries. You may find this is good enough.

Front-end development has been plagued by unclear patterns w/ weird names (MVC, MVVM, MXYZ...) since forever; everytime the patterns are criticized you hear "you did not understand it"; and new names keep popping up. It seems the industry is stuck remixing reasoning around nouns, and is unable to step back and reason around data.

BONUS:Sprinkle some CSP to get elegant concurrency, throw away callback-hell.Sprinkle some React to get fast DOM manipulation, throw away Flux (heresy!) - it has way too many names to worry about (action creator, action, dispatcher, callbacks, stores, store events, views) and encourages some bad practices around use of stores.

At the moment I'm sold on Mode-View-Intent, which is more delarative and non-OOP. I also have the feeling it lets me compose a bit more easy.

 DOMStream = view(model(intent(DOM))) DOMStream.subscribe(render)
intent() takes the DOM, wires up some interactions and returns streams "of" these interactions

model() takes streams of interactions, wires them up with data retrieval and mutation streams and returns these data-streams

view() takes the data-streams and uses them to create DOM mutations-stream, which it returns.

The nice thing is that these observable streams are really nice to filter, map, debounce etc. Also, it helps with fast realtime data stuff, because you can easily wire up these fast streams with a tiny part of your app and the rest of it won't even notice (which is a bit ugly if you got a big state-tree that represents your whole app state).

The not so nice thing is, that controlling them completely declaratively has a steep learning curve.

The whole "x is dead" is pretty common headline pattern. It's dramatic, extreme and often just an exaggeration.

I can guarantee that MVC is still used on the fronted as on the backend. People are still generating value from MVC apps.

Perhaps it's not held up as the holy grail, since the new holy grail is pronouncing it dead. Perhaps it is dying. Dead it is often not.

After building out some front-end MVC work, I can see the value in Flux architecture and React components. I'd have a hard time justifying a rewrite though. It's still very much alive there for me. That's also the case for many others.

I closely follow the Elm way (but in javascript with React), and it's still pretty much MVC.

 Model = the state, Controller = the update function changing the state based on action. View = declarative, need to send actions to change the state. Gets redraw on state change.
Redux/flux are also similar.

The idea of MVC, as far as I'm concerned, is to separate the View (Declarative as much as possible), the State (Just data, no logic) and the Controller (Business logic receiving commands/actions/called/whatever which changes the states and let the view knows that it needs to update).

Is that pattern dead? Far from it.

nwienert 2 hours ago 0 replies      
We've sort of evolved in our stack, which leans heavily on two less-popular options (MobX + Horizon), towards a pattern that I now think of as invaluable.

I started calling it Model-View-Store recently as I think that best describes it. There are a few unique things here that I think are valuable.

Starting with Models: Models all return observable values. So if I query for a single record I get back an observable object, or a list, observable array. I define `@query` decorators on the models to set up these queries. Model's include prop validation, normalization, consistent operation names, and more.

Views come in two types: application and presentational. App views are all decorated to automatically react to mobx observables, so you can literally have a Model `Car` and in a view call your query `Car.latest()`, and your view will trigger the query and react to it accordingly. One line model <-> view connections!

Then you have Stores: they are just logical containers for views. Any time a view needs to do more than some very simple logic for a view, you can attach a mobx store to it with very little code. Stores also can manage the data from the Model (and because the Model returns observables, this is usually a one-liner). But they don't have to. Stores are located side-by-side with the views they control (and are be passed down to sub views when needed).

I've been working on this system for a bit now along with our startup and we've been able to deliver some pretty incredible stuff very quickly. Having a consistent model system is crucial, I can't imagine programming without having prop validation and a single place to look for my model queries.

Going to be releasing pieces of it over coming weeks and hopefully a full stack example thats really legit soon.

caretStick 10 hours ago 0 replies      
MV arises naturally. You can run the entire application logic without UI components, and you can test it that way also.

Other abstractions are designed similarly to allow tests against pieces of the internal API in total isolation, though separated on different lines. Maybe you have transient state stored in view models while persisted state is stored in models. The isolation only helps as size grows, and it can keep size under control mostly by having a good data model for what each component / layer / aspect actually does.

It makes it easier to rewire everything when you start with a switchboard. UI changes are either "Oh my god we're going to have to re-write so much stuff if we do it that way!" and you wind up not making drastic UI changes or "Sure, we can make that thing tickle the controller instead of that other thing."

Agreed. MVC has always been sort of an awkward pattern for frontend web development. The fact that the DOM is extrinsic to the JS runtime can lead to a messy collaboration of MVC components. An input that makes an AJAX request on each keystroke and renders the results to a list (typeahead.js for example) is easy to implement but involves quite a bit of indirection with this paradigm.

That being said, I don't know how to feel about Angular 2's approach to components. Decorators are useful but can diminish the benefits of component based architecture when misused.

I wouldn't say MVC is dead in the front-end, rather I would say MVC is a necessary stepping stone towards modern front-end architecture. It still has some kind of model, view and whatever the controller is called.

Before the time of Single page applications, MVC was not practical as the state of the page would be destroyed as soon as you click on a link. With the whole "single" page approach your page lives on and your applications remains. This was the considered the "holy grail". We are thought all the problems are solved, but then came the performance and memory leak issues. Because the page lives on throughout the user journey, memory management became a problem.. and so was SEO. As always front-end will continue to change rapidly year after year and it's now all about Flux/Redux and Universal javascript?

Saying MVC is dead is like saying "CPU" is dead, no it's not, but it will always keep on improving.

Cute. That's what BeautifulSoup is good for.

I'm a longtime user of BeautifulSoup.

BeautifulSoup does not use or create "the DOM". It does convert HTML into a tree, but that tree is somewhat different from a browser's Document Object Model. For most screen-scraping purposes, this doesn't matter. But if the page uses Javascript to manipulate the DOM on page load, it does.

I have a tool for looking at a web page through BeautifulSoup. This reads the page from a server, parses it into a tree with BeautifulSoup using the HTML5 parser, discards all Javascript, makes all links absolute, and turns the tree back into HTML in UTF-8, properly indented. If you run a page through this and it still makes sense, scraping will probably work. If not, simple scraping won't work and you'll probably have to use a program-controlled browser that will execute JavaScript.

Some examples:

FBI operated 23 Tor-hidden child porn sites, deployed malware from them arstechnica.com

I feel like people are getting mad at the FBI for not pulling the trolley car lever in the right way, which is a valid thing to be mad about, but I believe the FBI made the right choice.

First, let's not rely too heavily the analogies with drugs or prostitution. The differences between CP and drugs / prostitution are too large to ignore anyway.

CP consumers are often producers as well. That's a factyou want CP, so you make some yourself and swap it with others to get more. This isn't universal but it's common enough that you should know about it. So the visitors to the CP web site are not all just consumers of CP but many of them are producers as well. This is relevant because you have to weigh the damage of distributing CP against the benefit of catching people who produce CP. People have stated that distribution revictimizes the children, but I would weigh that against the ability to catch people who were either producing their own or at least supporting other producers of CP.

So the FBI discovers this server, operates it for less than 30 days with a Tor exploit, and catches 200 people using the site. Yes, the FBI was complicit in the distribution of CP, but rephrased as a trolley car problem, this is basically like not pulling the lever, allowing the distribution to continue for a short time, and using that to catch 200 consumersand how many of them are producers? You can pull the lever now and stop the distribution of CP, or you can let the trolley barrel down the tracks for a short time and save all these people somewhere else.

(People are saying that the exploit may have done damage to other police investigations from other countriesI don't see any evidence that the exploit damaged the computer, merely that it leaked information about the computer.)

I think there's a rather extreme hierarchy of wrongs here.

1. The crime that utterly dwarfs all others is involving children in the making of child porn.

2. After that, the crimes that dwarf all the rest are those that provide financial or practical support to child porn makers. Consuming child porn is generally regarded as one of those, and I'm fine with that categorization.

3. I'm sorry, but violating a victim's theoretical privacy by distributing the images a little further doesn't seem to be nearly as big a deal as helping to prevent the next live video of child porn from being made.

I'm usually regarded as being pro-privacy, but privacy is not something to be a rabid extremist about. Preventing physical sexual abuse of children, on the other hand, is a fine area for extremism.

This is less like a drug or prostitution sting where the mark is arrested before the contraband can be consumed, and more like a hired hitman sting where the victim is actually murdered.

From a moral point of view, Child pornography is de-ontologically wrong. Nothing can justify its existence. Even if such a sting managed to shut down the entire industry, it would be moot to attempt to argue for its moral goodness in consequentialist terms.

The FBI could have used other means to establish criminal intent in the visitors to the websites along with the fact that they had used Tor to search out and visit those websites in the first place. They could have made prospective viewers engage in a series of incriminating acts such as requiring them follow a series of links with the promise of finding the material, or making them refresh the page. There was no need to provide the actual offensive material in order to make a solid case.

This is about the Freedom Hosting hack in 2013. In 2013 Wired wrote

> On August 4, all the sites hosted by Freedom Hosting some with no connection to child porn began serving an error message with hidden code embedded in the page. Security researchers dissected the code and found it exploited a security hole in Firefox to identify users of the Tor Browser Bundle [https://www.wired.com/2013/09/freedom-hosting-fbi/]

However, as far as we know, unlike the more recent Playpen thing, in the Freedom hosting case the FBI did not actually serve child pornography, they just displayed an error message. I don't see anything in this article that suggests otherwise.

I once experimented with a Tor router on a VM that isolated another VM's internet connectivity.

The idea was |Stealth VM| --> |Tor router VM| --> |Virtual Box NAT|

The Tor router VM was running redsocks[0] to route all TCP traffic through tor's socks proxy interface. The stealth VM also used tor's DNS service.

That way, even if the stealth VM is compromised, it can't access the internet directly.

I have no love for those who visit child porn on Tor, but in general I am now very wary of the FBI. I can't help but feel it's a powerful organization that's slowly turning into a dark oppressive one. The power grab from the CIA for the Petraeus affair. Using the sensitive nerve of terrorism to demand Apple unlock a phone. Throwing a last-minute wrench in the Clinton campaign. This is not going to end, especially under Trump.

So, is getting someone arrested as easy as spoofing their network information and visiting those sites? I can already imagine trolls using this to have people swatted.

I think the clear differential here is that compromising the server and tracking its users while it was in operation by Freedom Hosting would perhaps be "OK" but confiscating the server, moving it to HQ, and then operating the site themselves is decidedly not.

Keep in mind, you can't just pause the site and expect your targets not to notice, they had to actively maintain the site (and consider what that means) to keep their targets coming back. It's disgusting and disturbing. And if it's what we know about it, it's also just the tip of the iceberg.

At least with Fast & Furious I think it was real criminals running the guns and just a failure to intervene. I think a failure to intervene here would be seen as unacceptable as well. But here we have way more than failure to intervene, they effectively provided the guns and helped run them across the border.

Forget the Firefox Tor browser, use Whonix

Two Virtual Machines, the one you actually use for browsing and stuff only connects through the gateway virtual machine.

If an exploit breaks out the firefox skin, it is just in the host VM, if it somehow breaks out of the host VM it is in the gateway VM.

We could keep going down possibilities, but we are far removed from attack vectors that actually exist.

I understand the ban on child porn is justified via the interstate commerce clause:

Federal jurisdiction is implicated if the child pornography offense occurred in interstate or foreign commerce. This includes, for example, using the U.S. Mails or common carriers to transport child pornography across state or international borders. Additionally, federal jurisdiction almost always applies when the Internet is used to commit a child pornography violation. Even if the child pornography image itself did not traveled across state or international borders, federal law may be implicated if the materials, such as the computer used to download the image or the CD Rom used to store the image, originated or previously traveled in interstate or foreign commerce.


Theoretically, would a general citizen be exempt from the ban if he manufactured his own CD-ROMs, and his own CPUs in-state?

It might be illegal for them to operate the sites for extended periods of time. It doesn't seem illegal for them to deploy malware as part of an investigation. I'm looking at (f) here:


So the worst that could happen is that the evidence gets thrown out. If they weren't going to otherwise be able to nab the person, the worst that could happen is they lose the case.

Sad for the artistic loss but also glad he died at peace after a rich life spent doing what he loved till the last moment. He joins a special list, alongside Hintjens who also passed recently, of those who manage to strip the dread from death and stress the importance of 'tidying up' over passive acceptance as one enters the final days.

The big change is the proximity to death, he said. I am a tidy kind of guy. I like to tie up the strings if I can. If I cant, also, thats O.K. But my natural thrust is to finish things that Ive begun.

For some odd reason, he went on, I have all my marbles, so far. I have many resources, some cultivated on a personal level, but circumstantial, too: my daughter and her children live downstairs, and my son lives two blocks down the street. So I am extremely blessed. I have an assistant who is devoted and skillful. I have a friend like Bob and another friend or two who make my life very rich. So in a certain sense Ive never had it better. . . . At a certain point, if you still have your marbles and are not faced with serious financial challenges, you have a chance to put your house in order. Its a clich, but its underestimated as an analgesic on all levels. Putting your house in order, if you can do it, is one of the most comforting activities, and the benefits of it are incalculable.

This is a wonderful article about Leonard Cohen:


The quote that stood out the most for me:

"In a pursuit like rock n roll, which is entirely devoted to redemption, Cohens ideas were not only old but radical. His peers all insisted that salvation was at hand. To go to a Doors concert was to stare at the lithe messiah undressing on stage and believe that it was entirely possible to break on through to the other side. To see Cohen play was to gawk at an aging Jew telling you that life was hard and laced with sorrow but that if we love each other and fuck one another and have the mad courage to laugh even when the sun is clearly setting, well be just all right. To borrow a metaphor from a field never too far from Cohens heart, theology, Morrison, Hendrix, Joplin, and the rest were all good Christians, and they set themselves up as the redeemers who had to die for the sins of their fans. Cohen was a Jew, and like Jews he believed that salvation was nothing more than a lot of hard work and a small but sustainable reward."

May you rest in peace, Mr. Cohen.

It seems like so many of my favorite musicians and songwriters have passed in the last few years and its a struggle to figure out why. I'm a millenial with a wide taste in music from the early 20th century blues to contemporary EDM but it seems like the musicians whose talent you could just sense with every note and lyric are rapidly disappearing. I should be too young for this kind of cynicism but its an easy trap to fall into when comparing Dylan, Bowie, or Cohen to some song on the pop charts or an artist in the overwhelming field of independent musicians.

It's a sad day but I can't help but marvel at the universe. It is a kind of unique, rare beauty when a life-long artist like Bowie or Cohen close out their final chapter by releasing an album within weeks of their death.

I am reeling.

Leonard's music had an uncanny sense of timing, both musical and cultural. He referenced the external, political world, indirectly - not through selfishly inward bullshit, like many of his contemporaries, but by sifting it through relationships with others and his relationship to the divine.

As I am writing this, the next article in hackernews is about Peter Thiel and his ascension to whatever office he is seeking in Trump's cabinet. His views on the damage women and minorities have done to Libertarianism (whatever that is), and how democracy is shit are well known, and I will let you judge how Palantir has benefited humanity.

The thing that gets me is his straight faced desire for immortality. Note that he doesn't wish for immortality for someone who is great, he wishes it for himself.

RIP Leonard. You already are immortal.

Maybe unjustified, but I'm always kind of suspicious of a post which is largely focused on raw data (like this one) and which presents only pie-chart visualsations [0].

Yes, Python has a pretty dirty history, with many people choosing to stick to the Python 2.7 that they knew and loved. And yes, commercial software tends to move waaay slower than the wider community (many banks are still running COBOL). If you're focused on making money and pleasing clients then "it worked for us before" is always going to be the strongest argument.

Major players in the Python eco system have pledged to move away from Python 2 [1], and if we had non pie-chart visualisations, I'm sure we'd see huge trends towards Python 3 in the last year. Even slow-moving corporations are starting to use Python3. Yes, MacOS defaulting to Python2 is still a problem, but Ubuntu switching to default Python3 is already a huge step to get companies to move forwards.

When the latest stable releases of the primary environments are defaulting to something you have to have very good reasons why not to use the default (even when it's easy to change the default).

Administrators (in the old school not the new "everything in containers") don't like using non-defaults.

Former Python developer here. The problem was two-fold: Python 3 broke backwards- and forward-compatibility (in a practical sense: there were workarounds, but libraries didn't necessarily use 'em, and Python is nothing if not a glue language); and for the longest time there really wasn't a good reason to switch. I think it wasn't until last year that it really started to make sense to go with Python 3 and by then I'd already switched to Go.

I don't follow the Python community closely, so I might be totally off the mark here, but my general impression is that it was shipped prematurely. From what I've read, in more recent years a lot of work has gone into easing the transition... But it seems a bit late. As an outside I wonder: did they fail to put in a reasonable effort at all in providing a smooth transition from the start, or did they try and failed to account to the realities of our world?

Recklessly breaking backwards compatibility without a smooth migration plan is hostile to developers. Although it's not a programming language, this is something that I think React has gotten right with their current versioning scheme [0].

Users generally update by default, if thousands upon thousands didn't it's because someone else fucked up.

I find it funny how a small group of people thinks they know better than the outer community, to the point that they feel like they should have a say in what thousands of businesses use to run successful code.

More than this, I would argue that most people using Python 3 are those new to the language. This is only from personal experience, so it's really just anecdote.

PS: In a kind of jesty side-note, I know the general argument is that "python 2 was broken", but really, how broken can something be when thousands of businesses depend on it and more than that, choose to keep using it when a "better" alternative comes about?

Im not sure why but the Mac has not installed a "/usr/bin/python3" so I continue to avoid 3.x migration (aside from minor things like "__future__" imports for division and print_function).

I dont want to add a dependency for end users when my current code works fine with the built-in Python at 2.x. Nor do I want to bloat the size of downloads to embed something like an entire interpreter binary. (Swift has the same issue; there is currently no way to refer to it externally, as it is in flux; I do not want to embed loads of Swift libraries in every build so I will wait to migrate until they have stabilized binaries and made them available from a common root.)

I expend considerable effort that I am not obliged to expend to use Python 3 whenever possible. I'm sure that I'm not unique.

Right now in my life the major things stopping me from using python 3 for all the things are.

 * Ansible * Two large in-house developed apps taken over from previous devs * Debian Wheezy
And as you can guess, at least one of those will hopefully disappear soon.

Other than that I try to use python 3 as much as possible. I know a lot of the workaround for getting pyvenv working on various distros for example.

I also know about a lot of alternative libs like ldap3, dnspython3 and more.

this headline is a bit much. 1/3rd of new projects use Python 3! A lot of people are excited about the language now that a lot of the warts have been dealt with and language compat is higher than ever.

Though all it takes is one dependency to throw a wrench in the plans, the major projects are Py3 now.

Though porting large python 2 projects is still a huuuuuge pain. This is more a result of python 2 badness than python 3. But a lot of work.

Anecdotally, we had a simple events API running Python 2.7/Flask/uwsgi/nginx that needed to do quick I/O operations on a growing # of HTTP requests. To increase throughout, we experimented with Python 3 for its async/await style concurrency. It didn't seem to help much and we ended up just rewriting that API in Go and see way better throughout-to-resource ratios by shipping 5mb binaries to Docker & Kubernetes.

Point is, we're a hybrid shop that does all first pass services in Python 2.7 and then move them to Go when they become suffiently trafficked and/or critical.

Coming from a country with an extended alphabet, I've always been aware of encoding issues, especially before almost everyone settled on using UTF. So the treatment in Python 3 (and equally in Go) is a game changer for me and many other language users out there. I'm not saying that, say, American developers don't need to support other alphabets, just that it's less pressing since they don't tend to deal with them on a daily basis.

So for this feature alone, I'm all in on Python 3.

I've recently started using python a lot more, it was a natural progression when I moved from using a windows dev machine to a mac book. One day I needed to do something quick, and python was the quickest way to do it. I typed python into my terminal, saw 2.7, and built from that. I had no incentive to look into upgrading, I had everything I needed to accomplish what I wanted. My good experience then has grown to the point where it's probably the second most common tool in my toolbag, but it's still an "I need to do xyz, and I don't care how it looks I just want to see if this will work". So I still stick with the defaults. I only think about using the latest greatest tools if I think the code I'm writing has long term potential.

A lot in here about Defender/Microsoft Security Essentials.

> [MSE] doesnt have: parental control, built-in VPN, webcam protection, password manager, backups, exploit protection, protection for online banking and online shopping, proactive protection against future threats and dozens scores hundreds of other features which are all useful in providing maximum protection and a better user experience

That's exactly what I like about it. Stuff the "user experience": I don't want an AV product that tries to run my life for me. (I don't want Windows 10 to do it either, which is why I tried it for less than a week and went back to Windows 7.) AV products are bloated, difficult to use and always in your face when they should just silently remove viruses. Which is what MSE does for me.

I've felt like AV software is often worse than the viruses: intrusive, slow, ineffective, getting in the way, and not once detecting anything.

Pretty much all of my "family tech support" is related to the AV doing something stupid like auto-deleting cookies or flashing up big scary messages for something trivial.

However Windows Defender seems to be good for me on Win10 - it just sits there out of the way, I don't even know its running. I LIKE the fact it doesn't have "online protection" or password managers or parental controls or whatever. It feels lightweight and does not cause everything to become 3x or 4x (or worse!) slower like every other AV software I've encountered

Whenever I go to perform family tech support I remove any random AV software they've been tricked into installing and just leave Windows Defender and that usually solves the issues (obviously making sure they are up-to-date on patches & still using 2FA)

Microsoft has a problem - poor 3rd party software and drivers make Windows extremely unreliable. Microsoft takes the blame, and Windows looks unreliable. Apple takes a different tack, they simply lock down their APIs and ecosystem to avoid this. Is Microsoft trying to go the Apple route - but maintain some openness? Giving 3rd parties core low-level APIs is ripe for chaos.

I had to install Kaspersky on my main laptop since some VPN software imposed a policy that it installed and up-to-date to connect to a contractor's secured network. It was absolutely terrible. It killed my battery, slowed my machine, killed my TCP stack at one point, interfered all the time, and became generally unbearable. It frustrated me so much, I now do all network operations via a secured VM to avoid the Kaspersky curse on my main work machine.

This seems to be mostly about A/V.

There were all kinds of bad questions. The worst one I remember is somebody asking why they were not allowed to hold a kernel mutex across notifying a kernel-space A/V deamon & waiting for it to respond (deadlock?).

After seeing multiple questions like this from these folks, I resolved to never run a 3rd party A/V suite again, and have run nothing but vendor provided A/V.

It's the dirty speaking of the "poorly washed". Kaspersky is said to faked malware to harm rivals (http://www.reuters.com/article/us-kaspersky-rivals-idUSKCN0Q...). TrendMicro allowed remote command execution on the user machine (https://bugs.chromium.org/p/project-zero/issues/detail?id=69...). Probably Microsoft is right, your PC may be better protected without a AV, using an AD block instead for example. Probably not (I'm not a specialist in the low level stuff anyways). But the point is that MS is fighting with tools it has (in an ugly way). But it's widespread. Apple enforces Safari on iPhones for example. Amazon explores bias in its marketplace (http://dealnews.com/features/Are-You-Really-Seeing-the-Best-...). Kind complicated, but that's how the world is. Doing all for a higher profit. Because of that I'm sure that Kaspersky would do the same if they were in their position. Perhaps a little different, but taking advantage of its size to increase their profit for sure.

Re: Microsoft removing 3rd party software -

A friend of mine runs a 3-person software company making desktop Windows software. Nothing terribly exciting, think - a ToDo list or similar. They put nothing in the kernel, stick to documented API, make no deep tie-ins into the system (e.g. Windows Explorer extensions). Just a perfectly simple standalone piece of software with minimal dependencies that can run even on XP.

Not two months ago they started getting reports that the software was disappearing from users' machines. The Start menu icon was still there, as was the Uninstall entry, but the EXE was nowhere to be found. Naturally they thought of the antiviruses, but there was no pattern. Fast forward two weeks and the only commonality between all reports was a freshly installed Windows 10 update. The update silently wiped their software off. And to understand why that happened or to file a "false positive" report with Microsoft, the only option was to cough up few hundred dollars for opening a "priority support" ticket with them. Not everyone was affected, just a fraction of a percent. You could still reinstall the software and Windows won't make a peep or complain in any way.

While it made very little sense, it still clearly showed that users were no longer in control of their machines. Moreover, Microsoft outright lied when they said "all your files and apps will remain where they are" while installing an update.

So it's not just about loosing control over your own computer, but it's also about being treated like a sheep that Microsoft owes no explanations to and can do what the hell it wants. I sure hope Kaspersky Labs will have enough rage, funds and patience to drag Microsoft through courts and whip it back in place.

Anti-virus software is a complete failure. Kaspersky is trying to save a sinking ship. AV isn't a good business because its a failed area of development.

The idea that Kaspersky is somehow radically better than other AV vendors is a joke. Sure, some of them are comically bad, but none of that are that good. "Good enough" is often good enough.

I'm a fan of Kaspersky's research. AV isn't one of the areas where people need to be spending their time, though. I don't know how you could say AV works with a straight face.

ALSO: MS isn't a monopoly anymore.

I think this article is mixing up three different things which is counterproductive when you're trying to convince people. Just go to the point (not the pointS).

1. Defender is not the best AV out there from a strict efficiency perspective (IMHO, Defender is good enough for most people and is quiet enough & bloat less enough compared to a lot of the competition).

2. Killing the competition in the specific AV domain is bad for security (IMHO, perfectly valid point).

3. MS is globally trying to kill any competition by abusing its dominating position (IMHO, another perfectly valid point).

2 & 3, while absolutely true, are shadowed by 1 which is a very questionnabe point.

Antivirus and firewall are two apps that I expect come with Windows, so as a consumer who actually paid for Windows 10 I don't care if Kaspersky is whining about this.

As messy as av/fw are on Windows 10, let's not forget how things were before in the bad old days; security products were sometimes as bad as the malware they claimed to protect you from. Remember when you helped family and friends and how Norton was so difficult to remove it required a dedicated removal tool? Remember the countless of cleaners that used all kinds of scummy advertising techniques to trick users into installing them, often decreasing performance and safety?

As the "computer guy" for a lot of people, I'm glad that AV+FW are included in Windows 10. I am, however, disappointed how sub par they perform and how user hostile they are.

On Windows 10, the firewall is completely opaque and Microsoft decided to remove the firewall icon from the tray. So users naturally don't know if it's installed or not or what it's doing. Also, it's buggy as hell because on more than one computer I've had to keep resetting it to defaults simply because it would regularly stop ALL outgoing connections. Took some time to figure that one out and for most casual users that would have been impossible to solve, especially since there is no freaking firewall icon to click on anymore.

The antivirus has a more visible and sane presence but performs poorly in the independent AV tests. For some reason it changes names more often than a porn star, further confusing users. The blog post fails to mention Microsoft Defender, the fifth incarnation of the AV on Windows 10, so there are five different AV that Microsoft offers/has offered.

Microsoft needs to improve the quality of their built-in security products, both how successful they are at protecting users but also the overall usability experience.

I believe that when I am using Windows, my interests are more closely aligned with Microsoft's interests than Kaspersky's. That's why I stopped using Kaspersky in favor of Microsoft's built in security product...and similarly why I stopped using Norton AntiVirus in favor of Kaspersky a few years before that.

Independent of that, running Kaspersky means installing Kaspersky's root kit. That's another low level vulnerability in addition to Microsoft's root privilege. It's simply more attack surface. Fully utilizing Kaspersky means sending telemetry to Kaspersky just as fully utilizing Microsoft's product means sending telemetry to Microsoft. I've no reason to believe Kaspersky less likely to be compromised than Microsoft.

To put it another way, Kaspersky's business, like many in the Windows ecosystem is to AdWords or bloatware their way to rents extraction while free alternatives exist. I'm ok with Microsoft making that model obsolescent and Kaspersky adapting or dying because Kaspersky's argument isn't that it provides significantly better anti-virus protection.

I have installed Windows 10 on two systems. One has MSE enabled and the other has Eset Nod32. Nod32 was installed on that machine under Windows 7 and after converting the OS to Windows 10 it continued to work. Windows 10 is now facilitating notifications that the Eset license needs to be renewed, but


Also, back in the day I had an HP laptop with an AMD Duron processor, and it came with Symantec AV. I had overtemp shutdowns. I diagnosed that the AV was using most of the CPU cycles by far. So I researched the providers and somehow Nod32 came out on top across two or three different AV shootouts. I replaced Symantec with Nod32 and the laptop ran so much better. After that I only ran bundled AV on new machines until I could get around to installing Nod32. Nod32 continues to behave appropriately.

On the machine that runs MSE instead of Nod32, there was a different application chewing up the CPU cycles: The HP support assistant.

System security should be built-in, not bolted on by snake oil vendors looking to make a buck. Nothing against kaspersky, I like them, but I'm with Microsoft on this. Games, browsers and other add-ons are higher-layer applications where competition makes sense.

If MS really wanted to make system security an even playing field where vendors could actually be effective, they'd make it modular (like Linux's LSM) so that admins could easily swap out security solutions without busting the system (slow, bloated, ineffective, etc.).

Vendors are a large part of the problem. They want more money, more often and in many cases really harm performance and do little to protect the system.

I ran into this when the Windows 10 Anniversary Update rolled out. In my case the program Microsoft uninstalled was a Start Menu replacement, so I didn't actually have a functional start menu for several hours after the upgrade until I got the updated version of the 3rd-party program installed.

This left me shocked, dumbfounded, speechless, and furious. Everything I've observed over the last 20 years says Microsoft honours backwards compatibility above all else. Raymond Chen has great blog posts about the huge efforts they used to go through. My understanding is that's why businesses have stuck with Windows; it'll keep running their 10, 15 ,20 year old legacy VB line-of-business apps even on their newest OS. Apparently Microsoft has now decided to throw out backwards compatibility? I don't understand this decision.

Pretty bad practices by Microsoft and sounds like that has a decent chance of costing them money in the EU.

However I think the point that having one monopoly AV decreases security because the bad guys can adapt to it is at least not as clear cut as it seems. Especially compared to the scenario of someone having multiple AV programs installed. AV programs themselves are excellent attack vectors, especially for the more skilled attackers so reducing the number has at least some theoretical benefit.

From my experience AV software makes life of small developers targeting Windows platform harder, so an argument can be made that Microsoft is actually helping independent developers by improving installation and update experience.

We often need to deal with user problems because the installation or update process was blocked by AV software without any user visible message. Also often an application is incredibly slow for some period after the installation because AV is doing some additional scanning/blocking (again the user is not informed about this and blames the application).

It's interesting to know that even 'large' companies like Kaspersky Labs are affected by this centralization of software.

In startup land this is common - I've seen so many bootstrapped startups fail because they were out-spent or their market was monopolized by big companies or big VC money.

Sometimes it feels like we're going to end up with one giant tech giga-corporation that will just own everything and everyone will be employees of it.

> Microsoft has even limited the possibility of independent developers to warn users about their licenses expiring in the first three days after expiration ... this is the crucial period during which a significant number of users seek extensions of their security software licenses.

So it's about profit, because the AV companies lose out in their historically most lucrative period to keep paying users.

this is why i don't trust microsoft azure. I recently had to watch a marketing guy trying to sell me on azure, every second slide had a big, bold OPEN sign on the upper right. An truly open company does not have the need to stress every second slide that they are truly open. I tried using the service-bus (it was not my choice) and stumbled up on https://github.com/Azure/azure-sdk-for-java/issues/465, it is open since february! Node.js and the Rest-API were not working either and i could not use the c# library from my mac since important DLLs were missing.

It was a scary experience and it will take some time until azure will gain my trust. What would help is entangling microsoft and azure into a s structure like google has done with alphabet. With the current structure clashes of interests are inevitable.

AV slows legitimate software that operates on large data sets to the point of it being unusable. Case in point:


User comment: "MacBookPro takes 17 seconds, my Windows machine takes 122 seconds."

Because of AV - fast on Mac, slow on Windows.

Security fixes and improvements should be made at the OS level. And it is: Microsoft, Apple and Linux receive fixes very quickly. No software editor will be able to do better than the OS to fix and stop threats.

I stopped using AV softwares a long time ago for the following reasons:

- It slows down your device (memory, cpu, disk access, etc.).

- It annoys you a lot more than it stops or solves any security concern. I've yet to hear from someone telling me their AV software saved them from an actual real virus... If this ever happens it's probably a damn advanced attack that even the AV software doesn't know about.

- It's extremely hard to remove, especially when pre-installed as a bloatware on a PC. Sometimes it's also installed as an extension of other software (browser, etc.).

- It usually takes wrong decisions (false positive) that lead to broken web pages, legitimate software that stops working, etc. And unfortunately the "standard" user has no way to figure out it's due to the AV. I can't count the number of times I had to work with my customers on figuring out what was making my website or software not run (or even not to install) on their machine.One time I had to write to an AV editor in order for my browser extension to be whitelisted. Never got any answer...

AV softwares can be easily replaced with common sense and a set of very simple rules.

- Have a hardware/software firewall that blocks everything expect what's required (allowing only web when initiated from the machine is enough in 99% of the cases). Every major OS now comes pre-configured with a software firewall which removes 90% of the threats.

- Use a strong email service or software (gmail, etc.). This way you reduce the likelihood that a virus, spam, or fishing email passes through.

- Don't open email attachments coming from unknown or non trusted senders. Even when the sender seems legitimate, double check that the email makes sense (not an unusual behavior), pay close attention to URLs, written language and words. Don't click links without knowing where it goes (domain name, https, etc.). Email remains the most simple way to install a virus or a trojan on someone's computer so be very very attentive when acting upon an email. If you use an email provider (like gmail), report the spam or phishing attack very quickly so that 1/it can be stopped quickly for others and 2/it teaches the Machine learning to do better next time.

15 years I've been applying these rules and I never got any virus without using any AV software. My devices run like a charm (PC or Mac).

While I'm a big defender of freedom and open source, I can easily understand and forgive proprietary OS providers choices with regard to the AV editors.

Quite frankly, I think the continuous consumer abuse by the windows antivirus vendors is something that Microsoft is listening to here, and making it much harder for questionably efficacious software to put you into a perpetual license loop primarily fueled by scare tactics.

Sweeney had an argument, and one that I think Microsoft is trying to address. Anti-virus software (including McAfee and Kaspersky) is responsible for so many daily fuckups in my corporate computing experience that I am aggressively removing it from every computer I can find, and I tell everyone I can do to the same.

It is good that Microsoft is making them justify their existence, use less deceptive re-subscription tactics, and in general providing very stiff competition for them. In this specific case, it not monopoly tactics, this is pro-consumer competition.

I hope people realize this, because I think most windows users read this and then immediately squinted and said, "Kaspersky, huh?" It took me over an hour to scrape that gunk out of the last windows 7 box I set up for my family, and I was happy Win10 kicked it to the curb for me on the upgrade I just helped with.

I hate how intrusive the Windows Defender is, it automatically deleted some executables of mine I know to be clean (false positives). Just disable that beast entirely, seriously (group policy or regedit). Makes your PC much snappier. Defender is my biggest gripe with Windows 10.

Having anti-viruses installed is for fools. I just upload every single executable to VirusTotal.com and make sure I know the source I downloaded it from - this is far superior to any anti-virus and doesn't slow down your PC.

I said this when Windows 10 was new and I got tons of downvotes. I say it again because it still holds true and needs to be said.

I don't hear anybody complaining about Apple's anti-competitive ban on AV for iOS.

Oh, wait, that's because iOS is orders of magnitude more secure than Windows and doesn't really need an AV product. Whereas Windows has been plagued by malware for decades. Nobody wants to buy AV in the same way that nobody wants to buy health insurance; it's an unfortunate necesssity in an imperfect world.

Unfortunately the tradeoff we're facing here is the "information feudalism" one. People aren't realistically able to secure themselves, so they end up having to pick a quasi-monopolist and delegate to them the ability to ban software. Such bans can be extremely arbitrary. Occasionally even your headphone jack gets taken away. But people put up with it because it works for them in a way that anarchy doesn't.

Microsoft would clearly love to make Windows behave like iOS: apps only installable from the store which has power of veto and takes a cut. Heck, Apple would probably like to do that with OSX. Neither has quite managed it yet.

I suspect the long term way out of this is a proper user-owned subscription-driven open hardware company, but that's a very hard thing to build and a hard sell to the average user.

Is globalization to blame? stumblingandmumbling.typepad.com

Globalization (and corporatization) creates money vacuums, and dead spots in the places that they replace.

Walmart/Amazon/Etc vacuum money and resources from the local (or "local-ish") community to their respective profit centers. It used to be small towns would be relatively self sustaining and much of the money staying within local boundaries, and while the cost of goods was higher at least buying them would support local businesses.

When a factory leaves a town or a company goes under from overseas competition it creates a big gaping hole in the local economy that frequently doesn't end up being filled. There are no companies coming back, and no capital available in the area anymore since all profits are sucked up.

Maybe all this is inevitable, but it doesn't quite seem so to me.

It was beautiful vision for corporations, get cheap workforce overseas. Invest billions into China and then wait for those billions to get back to USA. It was true in the beginning because China imported a lot of tech and goods. They didn't have their own tech. Everything would work great but Chinese were not so stupid, they thought we can create our own products with same quality with our own tech with money we got from west. So they built universities and took best minds from west to teach in those schools. Then they started to make their own products that started to compete with those that need mid-high tech knowledge to produce. At this point globalization stopped being golden egg of western countries economies. That's why you see decline in growth in high developed countries in Europe and USA.
Animats 6 minutes ago 0 replies      
The reason for the "productivity" decline may simply be that manufacturing and agriculture don't have many employees any more. Only about 10% of the US workforce is in agriculture, manufacturing, and mining. Those are the areas where, historically, there's been huge productivity growth. That's how that number got down to 10%. Yet US manufacturing output is at an all time high.

"Productivity" at the macroeconomic reporting level is total output / total workers. So productivity increases in manufacturing are divided by the total workforce size, which dilutes them.

Job growth is in the areas where productivity is low, such as health care and education.

Does anyone actually think globalism is going to be stopped? My guess is it will be harnessed. Corporations fled the US to increase profits - both to preserve taxes and ignore environmental regulations. Given no regulation to prevent/dissuade the exodus, they outcompeted the ones who didn't.

It would now take a very large effort that would look like protectionism to bring all that back. Can Trump administration pull that off?

Thanks for sharing your experience as another cautionary tale.

At Convox we have been running Docker in prod for 18 months successfully.

The secrets?

1. Don't DIY. Building a custom deployment system with any tech (Docker, Kubernetes, Ansible, Packer, etc) is a challenge. All the small problems add up to one big burden on you. 6 months later you look back at a lot of wasted time...

2. Don't use all of Docker. Images, containers and the logging drivers are all simple great. Volumes, networks and orchestration are complex.

3. Use services. Using VPC is far simpler than Docker networking. Using ECS is much easier than maintaining your own etcd or Swarm cluster. Using Cloudwatch Logs is cheaper and more reliable than deploying a logging contraption into your cluster. Use a DB service like RDS is far far easier than building your own reliable data layer.

Again thanks for sharing your experience as a cautionary tale.

If you are starting a new business you should not take on building a deployment system as part of the challenge.

Use a well-built and peer reviewed platform like Heroku, Elastic Beanstalk or Convox.

A lot of this was the motivation for writing the book we wrote on Docker in Practice [1]. The reality of implementing such a technology requires a combination of improvisation, technical nous, bluffing, and a willingness to work through the inevitable problems [2].

I've talked about the relative immaturity of Docker as a used system (outside of dev) [3] and am struck often by how rarely people understand that it's still a work in progress, albeit one that can massively transform your business. The hype works.

That said, Docker can work fantastically in production, but you need to understand its limits and start small.

There have been good guides, but they go out of date quickly! There's so much change (because it's still very much under development) that it's hard for someone coming to it fresh to figure out what's up-to-date and what isn't. For those of us working in container tech and tools this is a good lesson about making sure the entry curve isn't too steep.

If anyone is looking into orchestration systems, I can't speak highly enough of Kontena (https://github.com/kontena/kontena). While it is still in the early stages of development, it is a great "small-mid level" platform with a ton of features. The config and concepts are also easy to wrap your head around. We chose Kontena as Swarm is still unstable (imo not "production-ready" but I've seen counter-anecdotes) and Kubernetes was lacking some features we required. The devs have been super helpful with any problems we've had in deployment as well.

This article reflects our transition experience with Docker, it took us two years to finally feel comfortable (old chaps from decades of corp dev), but end result is very positive and rewarding. It is fair to say that this should be expected for any infrastructure migration, there is nothing wrong with being slow and careful as long as we are moving forward. Based on experience from our team, the problem has never been finding help/answers, problem is we were facing, one one hand, an encyclopedia of single page documentation like Dockerfile/docker run command, while practical guidances and gotchas are scattered around rest of teh Internet, blended with personal and business specific opinions. It is hard but eventually we figured the best way to work with containers from git to build server to deployment, that fits well with our productivity workflow;, as well as where to not use docker.

I agree with most of the points here, but some stuff is misleading. For example the "you have to rebuild after everything that code change" is ridiculous. Just use "COPY SRC/ /app" In your dockerfile, and in dev mount SRC/ as a volume over /app. There, hot reloading sorted for development.

Don't get me wrong, docker is one of the most frustrating technologies I've used (partly because it shows such promise), but a lot of the problems he describes can be sorted with the most cursory Google.

A lot of the issue I see him describe in production are fixed by Kubernetes. Compose works fine for local dev orchestration but pattern doesnt work for deployment. The ideal world would be that I can run my compose file on my cloud provider, but Swarm isnt there yet. I have to rewrite my compose file using kubernetes configs its not a 1:1 mapping but the high level connection are there if you think of Cabernets Pods as Docker Containers. He mentions orchestration across a cluster with Swarm is nasty, but its elegant w/ Kubernetes.

Docker Registry:

Obviously, there is no constraint permitting him to use a 3rd party service. Why to let Google Container Engine (GKE) or AWS ECR handle it for you?

Longer build times:

I think this is really where he is missing the mark. It sounds like he has a fundamental misunderstand that if you mount the source code in dev you have to do it in prod too and that you have to have 1 container. Not true: You can mount the source code in dev using compose, so you dont have to rebuild every time you change a line. Also, I think its a pattern in docker to try to keep your containers as atomic units of your app architecture. It sounds like they are trying to bake all competent of their app into 1 container (app + db + service, etc). Just break them up into containers, link them up w/ compose. This architecture them translates cleanly to one of the cloud providers for production: GKE or AWS.

DB and Persistence:

Yes, I think it is very clear that containers are stateless. So, yes if you want to run a DB in a container youd have to mount an external drive somewhere. There merits and risks of that are another discussion, but as he states its generally frowned upon to containerize a DB. (not completely sure why, some argument about stability of container and corruption of data) I talk more about this here: https://news.ycombinator.com/item?id=12913198


I think 12-factor style app containerized fit more smoothly into the docker compose style architecture. Accordingly if all you containers are logging to std out it, its all conveniently merged and printed out to the terminal if you run compose. Then on production, GKE handles it nicely too w/ the Logging system.

In conclusion, I think most of his problems would been avoided if he didnt skip researching Kubernetes and if he didnt make the mounting oversight. The other big oversight I think he did, at least he didn't mention, is that he has no deployment tool. I wouldn't be able to effectively deploy w/o a build tool like Jenkins. I talk about a lot of these issues and how to fix them here: https://news.ycombinator.com/item?id=12860519
