Hello this is Marcus, the guy who did the resolution independent illustrations. I just uploaded the current version of the site, so it will no longer freeze, when the image gets to small. I also updated the Tantalos image.

I am currently a bit blown away by the reaction to this. I finished this over a year ago but didnt manage to make it public till now. I presented this at a meetup in Berlin yesterday and someone asked for an online version, which I postet to Twitter then things escalated quickly.

So because a lot of people are asking: I am currently redoing my completely outdated homepage. The new one will include an in-depth explanation of what is actually happening there, whats the idea behind it and how I want to apply this to actual web design to make resolution-independent work more easy and less restrictive for both designers and developers.

Until then I will try to answer some questions here

Scalable GreetingsMarcus

This is incredible stuff. Zeus in particular is amazing. It all seems to be done with weighted objects and a clever way of rendering them, but it's indistinguishable from magic from where I'm sitting.

This is really cool! If you look at the source, it appears that the images themselves are defined as JS code, almost like a vector image. For example, Zeus: http://essenmitsosse.de/pixel/scripts/zeus.px

The author then has a renderer to turn these into pixel data. It seems to render them down to an actual pixel image on the fly.

The amazing part about the Tantalos slide was that its responsive implementation actually captured the ethos of the myth itself - no matter how far he reached, the fruit moved ever farther away. outstanding work.

Besides moving your mouse around, zooming in and out also works beautifully (might put a bit of a strain on your system though).

Given the sheer amount of work for one piece, with The Three Graeae appearing to be around 1000 lines of code, I'm also quite amazed he managed to produce seven. Brilliant, and Art indeed.

So freaking awesome, this just rules!

My faves are 1- Zeus, and 2- Teiresias

Those two look like they took the most work, and are most technically challenging. The Man-Eagle-Bull-Snake morph especially.

Halfway random tangent, and halfway related, but I'm really super looking forward to wider adoption of SVG 1.2 precisely because it adds absolute unit constraints in addition to the relative constraints, so you can do some of the same kind of stuff in an SVG image, and have authoring tools to support it. Not the pixel art side of it, and nowhere near as crazy as this project, but it will still be really useful.

This is amazing!

I really like that in "Teiresias", if you make the canvas narrow enough, the man jumping (presumably Teiresias) changes position and gets a white beard instead of white long hair. Just to still give the impression that it's an old sage, in small vertical space.

Holy crap, very cool! At first glance I thought it was just a neat little resizing trick, but then Zeus morphed right before my eyes and I did a double take. The way it responds to your movement makes it really effective in a way that would be extremely hard (impossible?) to reproduce in a static image or even a video.

FWIW, if you live in the U.S., then you benefit from having such data in great quantity, though I don't think it's sliced-and-diced to near the potential that it has:

Lobbyists have to follow registration procedures, and their official interactions and contributions are posted to an official database that can be downloaded as bulk XML:


Could they lie? Sure, but in the basic analysis that I've done, they generally don't feel the need to...or rather, things that I would have thought that lobbyists/causes would hide, they don't. Perhaps the consequences of getting caught (e.g. in an investigation that discovers a coverup) far outweigh the annoyance of filing the proper paperwork...having it recorded in a XML database that few people take the time to parse is probably enough obscurity for most situations.

There's also the White House visitor database, which does have some outright admissions, but still contains valuable information if you know how to filter the columns:


But it's also a case (as it is with most data) where having some political knowledge is almost as important as being good at data-wrangling. For example, it's trivial to discover that Rahm Emanuel had few visitors despite is key role, so you'd have to be able to notice than and then take the extra step to find out his workaround:


And then there are the many bespoke systems and logs you can find if you do a little research. The FDA, for example, has a calendar of FDA officials' contacts with outside people...again, it might not contain everything but it's difficult enough to parse that being able to mine it (and having some domain knowledge) will still yield interesting insights: http://www.fda.gov/NewsEvents/MeetingsConferencesWorkshops/P...

There's also OIRA, which I haven't ever looked at but seems to have the same potential of finding underreported links if you have the patience to parse and text mine it: https://www.whitehouse.gov/omb/oira_0910_meetings/

And of course, there's just the good ol FEC contributions database, which at least shows you individuals (and who they work for): https://github.com/datahoarder/fec_individual_donors

This is not to undermine what's described in the OP...but just to show how lucky you are if you're in the U.S. when it comes to dealing with official records. They don't contain everything perhaps but there's definitely enough (nevermind what you can obtain through FOIA by being the first person to ask for things) out there to explore influence and politics without as many technical hurdles.

Really interesting use of data extraction....

For developers and managers out there, do you prefer to build your own in-house scrapers or use Scrapy or tools like Mozenda instead? What about import.io and kimono?

I'm asking because lot of developers seem to be adamant against using web scraping tools they didn't develop themselves. Which seems counter productive because you are going into technical debt for an already solved problem.

So developers, what is the perfect web scraping tool you envision?

And it's always a fine balance between people who want to scrape Linkedin to spam people, others looking to do good with the data they scrape, and website owners who get aggressive and threatening when they realize they are getting scraped.

It seems like web scraping is a really shitty business to be in and nobody really wants to pay for it.

I'm pretty sensitive to these things. That said, if you look at the partial list provided (granted this was potentially cherry picked), we're looking primarily at disaster awareness stuff. Flooding, wild fires, and search & rescue. Not spying.

Military resources, such as The National Guard, get called up for disaster relief all of the time. I think I'd rather drones helping people in these scenarios than what they're primarily used for.

It's not just drones. Law Enforcement often flies surveillance flights, circling over locations of interest. These planes often have thermal/visual imaging video cameras and, according to some stories, may also be carrying other tracking or signal interception hardware (think Stingray). HN user jjwiseman [0] scooped most of the press about this.

You can locate such "interesting" flights right now, using your browser. Just open up ADSB Exchange Virtual Radar [1], which doesn't filter out flights with certain squawk codes like other online virtual radar sites do. If you do, select "Menu" from the map (with the gear icon), then "Options". Select the "Filter" tab, select to "Enable filters", select "Interesting" from the dropdown listbox, and select "Add Filter". Now you can zoom out over the country, and see all the "interesting" flights using the table on the left. Note any flights with the "LE" or "FBI" or "DHS" user tag.

Right now, as I write this, an FBI-owned aircraft is circling over the Norwood/Bronx area of NYC [2], tail number N912EX, registered to OBR Leasing (one of the "shells" that the US Gov't uses for registering its law enforcement aircraft), as mentioned in an AP story last summer [3]

Edit: Another one, flying around NW Los Angeles, right now: http://i.imgur.com/PwRpqRe.png

Edit2: Any aircraft squawking transponder beacon codes between 4401-4433 are engaged in law enforcement operations. More on the various squawk codes reserved by US Gov't operations can be found here (pdf link): http://www.faa.gov/documentLibrary/media/Order/FINAL_Order_7...

Let's play a guessing game! San Diego? We've got Miramar and Camp Pendleton here, along with crumbling infrastructure and terrible potholes. Although the city certainly doesn't need help finding potholes around here...

Using drones for this kind of thing actually makes a lot of sense, although not a $20 million militarized Predator.

It will take a few years, but drone use will trickle down from the military into federal and local enforcement branches.


I'm curious about the flight plan approval and filing process they go through with the FAA.

Also wondering if the flights show up on the 5 minute delayed ASDI API:


And if the drones carry ADS-B transceivers and if they show up on other transceivers during flight. (Which would make them visible/trackable to anyone ground or air based that is listening)

> "Sometimes, new technology changes so rapidly that existing law no longer fit what people think are appropriate," Stanley said.

Sometimes, maybe. I'd argue rarely. I don't see much difference between an unmanned drone and an unmanned satellite or a manned helicopter in terms of applicable law.

Believing that a new law is needed because computers/drones/robots/AI/whatever now exist can lead to bad laws, or laws that are out-of-balance in terms of punishment. (i.e., commit a crime - 5 years. commit the same crime WITH A COMPUTER - 10 years)

There's a lot of talk about the Posse Comitatus Act[0]. The real distinction is in "intent of the mission". A mission that is:

A)Conducted by United States Army or the United States Air Force, and

B)Conducted to enforce domestic policies within the United States

Would be in violation of the Posse Comitatus Act. However, there is disagreement over whether this language may apply to troops used in an advisory, support, disaster response, or other homeland defense role, as opposed to domestic law enforcement.[1]

From the article:

"The Pentagon has publicly posted at least a partial list of the drone missions that have flown in non-military airspace over the United States and explains the use of the aircraft. The site lists nine missions flown between 2011 and 2016, largely to assist with search and rescue, floods, fires or National Guard exercises.

"A senior policy analyst for the ACLU, Jay Stanley, said it is good news no legal violations were found, yet the technology is so advanced that it's possible laws may require revision."

This sounds a lot less dramatic than the article headline, but it's good that this is being reported and discussed publicly.

A couple of weeks ago, I was taking in some scenery around Creech AFB, North of Las Vegas. While there, I saw a Predator (although it might have been a MQ-9 Reaper) being launched from the airstrip.

It looked like a giant model aircraft getting launched when the wind hit it. Pretty cool at the time, although after reading this, I hope it was just a training mission over some non-existent Nevada AFB...

It's really weird how this article tries to frame the situation. It's almost like the startups feel entitled to the funding.

The point of funding should really be to enable faster growth than they might otherwise have been able to achieve, but if a business can't at least survive without huge influxes of investments then is it really a business that they should be investing in in the first place?

In theory this won't affect the decision making process of top-tier VCs. A good invesment is a good investment regardless of the prevailing funding climate.

In practice, I'm guessing if the LPs get cold feet, then VCs will be forced to triage their funding decisions accordingly. How much this matters given the sheer size of some funds, I'm not sure.

I'm interested in knowing more about the "25 Jenkins masters" that they have, and how much they have modified/built for Jenkins to make it work for them.

We are currently in a state of "big ball of plugins and configuration". A bunch of plugins have been installed, and lots of manual configuration has been put into jobs so that everybody has what they need to build their software. It has led to Jenkins being a "do everything" workflow system. The easy path that Jenkins provides, to me, seems like the wrong one - it makes it easy to just stuff everything in there because it "can" do it. This seems to leads to tons of copy/paste, drift, all types of different work being represented, and it is starting to become unmanageable.

Have others seen this happen when using Jenkins? How have you dealt with it?

For those wondering about how this applies to Node.js use a Netflix like myself, it's in there towards the bottom of the article:

> "As Netflix grows and evolves, there is an increasing demand for our build and deploy toolset to provide first-class support for non-JVM languages, like JavaScript/Node.js, Python, Ruby and Go. Our current recommendation for non-JVM applications is to use the Nebula ospackage plugin to produce a Debian package for baking, leaving the build and test pieces to the engineers and the platforms preferred tooling. While this solves the needs of teams today, we are expanding our tools to be language agnostic."

I'm a Netflix fan, as a consumer and an engineer, and this blog post just reinforces my fanboi status. Amidst the descriptions of deployment tools and pipelines one thing stood out for me: the fact that AMI bake times are now a large factor, and that "installing packages" and the "snapshotting process" were a big piece of this. Containers are definitely the answer to this problem. You can deploy base images with the OS and common dependencies, and have the code changes be a thin final layer. Of course with such a sophisticated pipeline based on AMI deployment this change would not be trivial for Netflix, but the bottom line is they have described the primary container use case perfectly, imo.

I have made this case before, but I will make it again.

The Internet is the largest information system in the world, and Google is the primary portal into that information system. Google's "organic" results are accompanied by AdWords results, which are based on a mixture of bid price and relevance. These ads are marked with a small "Ad" label that many people miss, and even those who know they're ads can't really "unsee" those results.

So, searching the world's largest information system provides results which have been biased by money. How does anyone consider this ethical? Why are we letting money influence the salience of information?

What if your local library (you know, those old things) had a card catalog with "sponsored" results? If this already exists, then maybe we're already lost. But it seems to me that as a basic rule of information ethics, the salience of information in a given information system should not be biased by monetary influence. Full stop, the end, no exceptions. If anyone has a counterargument, I would honestly love to hear it, because this has nagged at me for a long time. I simply can't understand how AdWords is ethical.

Of free people, free minds.The Internet will be the cure for all the social ills that humanity has experienced in the past.People will trade and talk with each other and that's how we can have peace on Earth!

We will be able to discuss, collaborate, create. We would be able to watch any film, listen to any song.

Some people called us "geeks", we liked to call ourselves "hackers".

We are not just hacking code, we're hacking a new world.


A quarter of a century later and most of those things are now reality. But somehow these great things have brought with them some hidden things. Things which we ignored or brushed off easily back in the day..

Like the fact that the Internet is now populated by the same demographic as the real world, not just hackers and dreamers. Now everyone is online.

We thought it would free us from oppression, but it is becoming the ultimate tool for oppression.

We thought it would give us true democracy, but it is becoming the ultimate moderation system for "foreign" though suppression and group think generator.

We though it will serve our needs, but it is becoming the thing that is telling us what to need.We thought it will satisfy our tastes, but our tastes are now being programed into us by it.

Of course we're still high from all the positive aspects and it's not in our nature to be scared of things, but that will soon wear off .. And when we wake up what will we find there ?

Either way, it is unstoppable and nobody can turn it off. So we only have to wait and see what it will ultimately turn into.

What will it be 25 years from now ? Will we still be able to discuss about this freely ?

Google could send people to places that are contrary to the user's interest, but that's essentially deliberately decreasing the quality of one of their products so I'm not that worried about it. If they do it's a (big) market opportunity for someone else.

I would go even farther: I'm not particularly worried about individual interests at all, on any subject. The Internet is very good at exposing them.

I am much more concerned with bad classes of actors than bad actors. We see many ways in which competition breaks down because entire classes of people benefit from working in synchrony. The classic example is politicians: crooked elections mean longer terms which benefits basically all of them.

The other classic example is the capital class. If everyone in the capital class plays by he rules of property then they can exploit the labor class. Once you're in the capital class there are few reasons to compete with private property. Social pressure mostly neuters whatever capital class activists might try to keep working.

It's these class barriers that we should be worried about. But new weapons (like search engines) and new villains (like Islam) make much better news stories.

This read like anti-Google FUD.

The basic argument is search engine rank determines trustworthiness of a source. This influences people's opinions on politics, what they buy, what they think, etc.

This is absolutely true, and the core of their research (it seems).

But then it goes into FUD territory when talking about Google backing Hillary. Hillary and Trump have received the lion's share of attention in media, social media, and such. Google searches SHOULD show them prominently.

Worse, the article basically finishes up with a "be afraid, be very afraid" approach that rankles me. "The new hidden persuaders are bigger, bolder and badder than anything Vance Packard ever envisioned. If we choose to ignore this, we do so at our peril."

No solutions or deeper analysis. No discussions on how a search engine should rank relevancy to search terms.

I personally have no doubt that mass-media, marketing, and the internet are shapers of opinions. Bias in the media, search engines, and such is a complex topic. Not something that should boil down to "Google could make it so Hillary wins" therefore you should be afraid.

Here is the actual study: http://www.pnas.org/content/112/33/E4512.full.pdf

I can't see how this is valid at all. We know that polls give biased results unless you are very careful with the sampling. Here people are self-selecting for a poll (eg via mechanical turk). Then you apply a highly contrived scenario that they are googling about a candidate. Then you ask them a bunch of questions, immediately, and proceed to draw wide ranging conclusions designed to increase your self-importance as much as possible. I mean, seriously, it's worse than useless.

This article is also written as if these findings are earth shattering. After conducting a small, biased, invalid study (Asking people in San Diego about an Australian election? How does that generalize to anything?) and finding a large effect Epstein says 'We did not immediately uncork the Champagne bottle'. Is that how psychology research is conducted? Researchers toasting large implausible effects in small biased samples that have no external validity?

I once read an article about surveillance with a title along the lines of "A Tale of Two Cities."

In it, the author explains that there are two types of surveillance cities that will emerge in the future: one where every park bench is rigged with a mic, every street corner has a camera aimed at it, and where all the data collected is funneled to law enforcement agencies; if you were mugged on some street corner, they'd be able to react to the crime swiftly and with high accuracy.

The other city is exactly the same, but all the data is made available to all citizens through an open API; so if you wanted to meet with someone on some street corner, you could decide for yourself if it was safe enough to visit, likely preventing the crime from happening at all.

Does anyone know what article I'm talking about?

Oh god. This article is so fucking disappointing.

What a quaint boogey man this "Search Engine Manipulation Effect" is. It even has it's own obscure little acronym, SEME, to appear more relevant.

I learned about the subtle effects of advertising by the time I was in fourth grade, and certainly understood how to ignore them by middle school.

Back when special holographic foil comic book covers and trading cards were new, I had already figured out that all of these "collectibles" were mass-produced, and would never wind up as valuable as, say Action Comics Issue#1, despite so many claims otherwise. This was something you could kind of figure out on your own. If your were easily amused by shiny objects though, you might not arrive at the same conclusion.

Meanwhile anyone could figure out that the influence of single frame inserts in movies was as potent and realistic as the subliminal messaging in John Carpenter's Sci-fi movie, THEY LIVE.

So too, with Search Engines.

Figure if a fourth grader can figure out the shenanigans of opinion and belief influence in advertising, and unravel the bullshit of religion before high school ends, then this other newer form of bullshit is similarly debunked by comparable intellects. If you're so stupid that you buy into bullshit, without multiple channels of factual verification, you're your own worst enemy.

Okay, okay, maybe this is good reading material for an elementary school classroom assignment, focused on current events. Sure, why not?

I was hoping this would be about technological manifestations of psychic telepathy through malicious use of functional MRI systems.

As much as I would love to imagine some powerful people intentionally influencing search results on a big scale, Google and Facebook and Twitter have no real way to make money from it. I would argue that it would only drive people away. I am sure that it happens to a certain degree, look at the marketing of Bernie Sanders on reddit, but a much bigger influence is your social circle and your source of new information. Social media mirrors people's attitude. If you see new tweets about an issue you don't particularly care for, there's a good chance that people you follow do care. It's basic psychology that you befriend people who share your views and interests. If all of your friends tweet or like or show interest in something then twitter will assume you do too. Twitter makes money from user engagement and so it's logical to show you things that your friends agree with because chances are you will too. I think a real issue is the lack of a source of unbiased information. Relevant information and information you agree with are very different things.

Megacorporations are bad for the internet for certain, but I don't feel very mind controlled by Google, as I almost always use Duckduckgo or Yandex. They produce fairly similar results, and I have the satisfaction of not shoveling the tiniest bit of money at a company I have likened to fat Vegas era Elvis.

I also doubt the results of their research. Nobody is going to vote for Donald Trump because he happens to appear first in a google search; that's just retarded. I think the fact that outsider candidates are locked out of legacy media megaphones and party power structures seems more harmful to democracy, and this has been accepted as "just how it is" for decades.

This article is speaking about something that has existed as long as mass media has. Whether it's google or newspapers or TV, the companies running the sources we turn to have control over what information we are exposed to, and can influence our views. Our grandfathers read the newspaper, our parents watched TV. What, google is a monopoly? Ok, so that's the big issue.

On the other hand, our susceptibility to having our political system be disproportionately affected by a company or two with a top-down chain of command is a reflection that our system of representative democracy has weak links and can be easily subverted.

I wrote about the solution to this a while back: replace voting with polling! Have people cast their voice for POLICIES not REPRESENTATIVES. It is much more costly to fool all the people all the time, than to fool them at election time, and then go on to lobby the representatives they chose.

Voting depends on turnout, which skews the results and is susceptible to sybil attacks (remember facebook's vote about the newsfeed that got 3% turnout?)

Polling doesn't. It can be refined using better and better statisical techniques. We can gradually replace costly and stupid elections where candidates talk about their penis, with polling of the population on issues like gun control etc. Replace the bickering lawmakers and filibusters with polling and threshholds.

In tangentially-related news, there was a lot of talk at NetDev about switchdev, a new Linux driver model for hardware-offload switching hardware.

It allows the kernel's Layer-2 and Layer-3 switching/routing configuration to be reflected down into the switch offload hardware, and the switch's ARP and MAC table data to be reflected back up to the kernel stack.

The overall idea being you can continue to use the same userspace tools to configure the routing/switching, and it all just magically goes faster if you have supported switching hardware.

That's a beautifully concise numbering system for sharing being used there.

Now if only we had descriptions of chemistry that were this terse. Imagine if this kind of problem solving, collaboration, simulation, and instant verification were the norm for synthetic chem. One of the comments -- "[Let's] use gencols to rub the ship against gliders and *WSSs to see whether there is a useful collision to maybe build a puffer" -- just blew me away. If this were chemistry, that commentator would have been suggesting automatic nanomachine factory discovery.

(InChI appears to be close. But vast amounts of data are locked up in obtuse formats are either Assigned-Names-And-Numbers style formats which are useless to indexing and similarity searches, or formats that embed non-relative coordinates in 3d space, etc, in such a way that computing a deterministic ID for sharing is practically a nonstarter.)

Very nice!

You might be interested in a simple proof I found of why c/2 and c/3 are speed limits for orthogonal and diagonal spaceships respectively.

Definition: In a gameplay of life, an "infinite lifeline" is a sequence of pairs (c_i,n_i) such that each c_i is alive in generation n_i and either c_(i+1)=c_i or c_(i+1) is adjacent to c_i.

Lemma ("Two Forbidden Directions"): Let x,y be any two 'forbidden' directions from among N,S,E,W,NE,NW,SE,SW. In any gameplay of life that starts finite and doesn't die out, there is an infinite lifeline that never goes in either direction x or y.

The lemma's proof uses biology. Say that (c,n) is a "father" of (c',n+1) if c' is the cell adjacent to c in direction x or y. Otherwise, (c,d) is a "mother" of (c',n+1). By the rules of the game of life it's easy to show every living (c,n+1) has at least one living father and at least one living mother. It follows (modulo some more details) that since the gameplay doesn't die out, there must be an infinite lifeline where each cell is a mother of the next, i.e., an infinite lifeline that never goes direction x or y.

Proof of c/2 orthogonal speed limit: If a spaceship went faster than c/2, say, northward, by the lemma, it would have an infinite lifeline that never goes N or NE. The only way it could ever go northward would be to go NW. Every NW step would have to be balanced out by an eastward step (of which NE is forbidden) or the spaceship would drift west. So every northward step requires a non-northward step, QED.

Proof of c/3 speed limit for diagonal: A diagonal spaceship faster than c/3, say, northeastward, would have an infinite lifeline that never goes N or NE. The only way for it to go northward would be to go NW. Each NW step would need at least two eastward steps in order for the ship to go eastward, QED.

This definitely looks like something I need to check out. I do a lot of one off analysis for small bioinformatics projects,and I've taken to sharing results in the Microsoft ecosystem via OneNote. I've wrapped knitr into my own library (knoter) which generates the html and figures, and pushes the whole lot up to OneNote in the selected notebook. OneNote works well for this kind of collaborative analysis, where I need to keep track of the whole discussion somewhere.

One thing I'm missing from my workflow would be a way to integrate in to an IDE so I just push a button, and it'll commit the code to a gist, and push the output to a OneNote for other people to comment on. I'm wondering if it would be possible to fork this, and tweak the calls to knitr so they use my library instead.

That's what I never understood about Microsoft. They're a software company. And some of it is absolutely horrible (Sharepoint), and some of it is the best in the business (Visual Studio).

There's a significant mindshare in Linux and Open Source. That being said, I don't understand why MS didn't provide Visual Studio, Office, and similar for Linux at a premium. For example, if Office was $499 for Windows, charge $999 for Linux. That way, they get the best of both worlds (use their software, pay them money). And their mindshare is significant as well, and this would increase it.

Maybe finally they are coming to their senses, doing just this. It's about time.

Personally never did R studio. Unfiltered command line is always more flexible, and prevents inertial lockin to a specific tool, OS, to a large extent. Now I'm supposed to do R in ultra-bloated Visual Studio?? I learned R precisely to get away from the inefficiency of the (in the past 20 years, functionally unchanged, visual-candy-only) Excel. How am I to be excited about adding this thick, lumpy MS gravy, to my pure R experience? So that when I do R on Linux or remotely I'm screwed? No thanks.

Addendum: Clearly the hive mind MS corporate drones are out in force today/tonight. I know everybody is enamoured with MS-Eclipse etc but R is best used unfiltered. Not hijacked into the laughable world of Windows and Visual Studio. I know from bitter experience that the Windows versions of R are terribly unstable by comparison with the Linux builds. I learned the latter precisely for that reason. MS is playing a fantastic marketing game but I was agnostic on platform until R on Windows started showing its catastrophic limitations. It's a second class citizen as soon as you venture beyond the basics. Take it from an ex R-on-Windows guy who uses R 10 hours per day.

I've never taken an illegal drug in my life. I've smoked a cigarette about 5 times. I drank in college but lately I've cut that out of my life as well. I had a security clearance with drug testing requirements for a while and now I just don't like the feeling of a hangover from alcohol or the risk of ingesting random plants/chemicals made by shady people.

In short: I'm the most vanilla, square, anti-drug person you can find. I don't want to use them, and I think other people would be better off if they reduced their usage as well.

Yet I can not for the life of me understand why drugs are illegal. Not just pot, all drugs. I'm totally onboard with making it our public policy that we want to reduce the use of drugs. That makes perfect sense to me. It does not make sense to me why anyone still believes that using the criminal justice system as the mechanism for getting to that goal is the right path. We are spending insane amounts of money on a failed approach while also generating huge negative side effects by creating an enormous group of people with criminal records. It's probably the worst thing this country has done to our own people since segregation and it seems like all of the policy people understand this. Why can't we get political will to do something different?

Complication #2: cummulative dosing error or interactions, especially multiple, independent prescriptions for similar opioids with different administration routes (patches, sprays, pills, injections)

Complication #3: overprescription of opioids because they're cheap, especially to veterans, which also leads to prescription and hard drug addictions.

Solution: opiods need to be singularly controlled at home or in the hospital by an integrated, blood/interstitial fluid measuring/dispensing unit to avoid OD and push back on abuse.

Plus, anyone taking opioids should also have narcan or equivalent antidote readily available, and wear a medalert QR code bracelet which lists relevant conditions and medications should they be found unresponsive.

Finally, avoid painkillers as much as possible and take the least dose which reduces stress level.

I have chronic pain due to a heriditary, incurable condition. Right now one of my ankles is in an elastic wrap to ease the irritation from arthritis. In our home, we did have a bottle somewhere of Tylenol 3, aka codeine. Regular acetominophen was usually what I got to help with an issue.

As I grew into adulthood, I knew the pains I experienced were directly related to my condition, and it was my desire to not really 'cloak' the pain, but avoid it in the first place. Preventive if you will. It helps, but it's clear to me that I wanted to be healthy, and if I have to occasionally take something, so be it. Naproxen sodium has worked quite well of late.

The point of all this rambling is that I simply don't want the hassle of becoming addicted to pain pills. Or sleeping pills. Or nasal spray when it's allergy season. I've lived with pain so long for my life that I'm kind of used to it, and I do say so as a point of pride. It's the body I was born with and it's the one I'll have to use for this gig, take care of it.

I don't fault people for wanting pain treatment. I think the way the system was set up with pills flooding the US was incredibly destructive, and highly indicative of the dangers of for-profit medicine as a system. Toss in the DEA's drug laws and it just turns patients into criminals and that benefits only a very limited group.

When I eventually started seeing commercials on TV for a treatment for opiod induced constipation all I could think about was Trainspotting and that we have a real, genuine problem on our hands in the US.

Lots of comments from people who have no experience with chronic pain aghast that doctors would fulfill patient "demands" for painkillers instead of treating the underlying cause.

Pain is self-report, so all a doctor can do is prescribe based on patient demand. Maybe they can't identify an underlying cause, or maybe the treatment (ex: back surgery) is too risky.

Spine surgery that might not work and can leave you with say, loss of bladder control? I'd take the pill every time, and if my doctor didn't just hand it over, I'd find another doctor.

This isn't really surprising. Opiates have long been used as both recreational drugs and effective analgesics. All the major opiates people abuse besides opium itself were created at one point or another as a painkiller. It's unfortunate, but they're also really good at their jobs. I think that if you need prescription painkillers you should have them. Taken without wanton disregard they're actually fairly safe, although physical addiction is always possible.

It's troubling the way this article presents the issue. Treating chronic pain is an enormously complex problem that clinicians have to deal with, especially as it gets bound up with collateral pitfalls of drug dependence, politics of health care delivery systems and conflicting pressures from patients, government regulators and others.

While unethical prescribers (not all are physicians) contribute significantly to rising misuse of opioids, the vast majority of practitioners want to do what's best for patients. As the article notes, there are few options for managing chronic pain, leaving opioids the only realistic choice in many instances.

None of the providers I know think opioids are preferable, but more like a necessary evil. They prescribe opioids sparingly, reluctantly, diligently. Patients have told me it's become increasingly difficult to get prescriptions for quite modest doses of opioid agents they've used for years without dose escalation. The tendency to throw babies out with the bathwater is not unique to this situation, but no less problematic.

Blaming pharmaceutical companies doesn't seem a constructive approach. Probably there's a lot of R&D going on in this domain without much success, meaning it's a very hard problem to solve. I'm certain that a major breakthrough would be eagerly marketed, highly likely the profit margins would be huge. Meanwhile, we're left with the status quo, and manufacturers are meeting market demands. Isn't that how our economy works? Pharma sales are already more highly regulated than nearly all other industries, what more should be done?

Few legal drugs are as controlled in the US as schedule II opioids. If there were no such controls it's likely that the number of overdose-related deaths would be higher than it is. No one knows what solution will work, the need to be being careful about changing "rules" should be obvious.

The article's advocacy of "medical marijuana" as an alternative is IMO inappropriate. Simply enough, research on the uses of cannabis components for pain treatment is in very early stages. Specific indications and side-effect risks are inadequately understood. Recommending use of these components as treatments for pain is premature.

This seems like a particularly limited article, although a better slant than many. The NY Times just had this (also not wonderful, but with some additional information) article a few days ago:http://www.nytimes.com/2016/03/07/us/heroin-epidemic-increas...

While the title mentions heroin, the article at least mentions that deaths are frequently due to more deadly prescription painkillers being mixed in. One thing I wonder that I haven't seen addressed (I'm not sure if there is even data available) is how many overdose deaths are due to use of multiple drugs at the same time (alcohol for example makes many drugs more deadly).

Hopefully there will be more and better reporting on the issue. IIRC (and wikipedia agrees at least), these numbers mean that drug overdoes are now killing non-trivially more people in the US than car accidents.

This is very interesting. It is a serialization format generalized to handle real references, including circular ones, and more complex data-types than JSON can handle. I think it's a very poor tagline, since "eval in reverse" sounds useless, and this lib is anything but. (no affliation btw)

The down-side is that a consumer has to run a full-blown eval() (as opposed to the more restricted JSON.parse()). This isn't that much of a downside in a typical webapp since you have full control over the browser process anyway, but it's deadly for cross-domain.

The upside is considerable for certain data-structures that are hard to represent in JSON efficiently, e.g. with a lot of denormalization.

A key concern for me is runtime efficiency, particularly compared to JSON.stringify.

If you're using yaml and templates then you've already lost. The only tool in this game that is not braindead is chef. Sometimes you need imperative things and conditional logic with iteration. If you don't have a real programming language then the contortions you have to go through gets really old really fast.

As for the deployment patterns. If you're in the cloud then you should be baking AMIs (or equivalent in your cloud provider) and shipping your configuration the same way you ship your application code, as native packages like .deb or .rpm. If you jumped on the docker bandwagon then your hosts are basically there to look pretty and host the containers which means you have some other way of getting configuration to your servers, i.e. etcd, consul, etc. so the problems brought up in this post don't exist in that setting. You are also probably using some kind of container orchestration system like kubernetes so again the problem of orchestration and deployment is offloaded to some other system. The only problem you have in that setting is doing a rolling deploy of containers and halting when things go wrong.

I think the only place any of these tools make sense now is some private on-premise cloud. Ever other place has already moved on.

Ansible has scaled really poorly to thousands of hosts for us. Things we have run into:

- Running a job against a single host will finish in 3 minutes... running that exact same job against thousands will take well over an hour and max out your machine.

- Running against more than around 3k hosts will somehow consume all 60GB of RAM and trigger the oom-killer

- CPU usage on the ansible runner is absurd for a large amount of hosts. We're currently using a c4.8xlarge (our biggest box) just to run deploy jobs and have them finish in a reasonable amount of time (10-15 minutes)

Slicing up our inventory into chunks and running them on different servers sucks big time and is pretty hacky. How do I combine the results? Can't do orchestration like "Run X on these roles first, then run Y on these roles when you're done".

Most likely what I'm going to do is have a single server execute ansible doing only the following in async (aka CPU friendly) mode:

- Upload a current copy of ansible to S3

- Upload the configs to the target machines with ONLY the secrets that role needs in plain text. (I'm not putting my vault secret on every box!)

- Have the servers pull it down and execute in --connection=local mode.

- Wait until each remote finishes

All that said, I LOVE LOVE writing stuff in Ansible. It is so easy to read, follow, and understand. I picked up most of it in a day or two just by reading their "Best Practices" page. Getting it to work at scale hurts though :(

> it works reasonably well on the scale of thousands of hosts

I could see this if you're working from one really powerful machine... no, that won't work, it's constrained by SSH, not hardware specs.

I could see this if you're calling Ansible on another host... no, then you have to copy everything out to the sub hosts, who have to copy everything out to their sub hosts... A scalability nightmare.

You can use redis as a distributed store of truth and... wait, what? Now there's a blog post worth reading. Show us how to scale Ansible with real-world examples using redis and autoscaling groups. Please.

Got it. I can see this work reasonably well if you're willing to wait 10 hours for a deploy to complete. Personally, I'm not.

> If you want to have 1000 forks, that will cost about 30 GB of memory

Ansible is not, nor has it ever been, limited by available memory. It's limited by the number of concurrent SSH sessions it can handle while copying every single module to be executed to that host.

There's plenty of reasons and ways to use Ansible for deploying code. Some of the post has accurate and reasonable information, but the scaling portion is pure fantasy right now.

This might be off-topic (or it might be a breath of fresh air if you're tired of configuration managers) --

I've been toying with the idea of making a trolling-but-no-really deployment framework called tarpipe, and all it does is take some files on your host, get em to a $place in one step, and run hook.sh. Oooooptionally, do some dir moves and symlnks to keep a prior state backed up, and service stop|start on either side of the mv/ln, to minimize downtime.

Usage could be `tarpipe ssh user@host` or `tarpipe <(echo "cd keke && bash -c")` just as easily.

It goes without saying that this simply wouldn't be comparable to Ansible, Chef, or other CM because it's too simple. It doesn't help manage state if it escapes $cwd. But if your application can curb its enthusiasm to a directory... boy is it simple if that's true.

I already do this on the daily to crashland my bashrc and dotfiles on any new remote host. Maybe this kind of explicitly zero-dep deploy would be useful for more situations.

Would anyone have a use for that?

I have done several small deployments (under two dozen servers) with Chef, Puppet, and Ansible. I've also evaluated Salt and worked with other people's Bconfig systems. Ansible is the best for my situation, hands down. I no longer have any of the others in use.

Ansible is easy to reason about - it's never surprised me once in use. You have about an order of magnitude less to learn when compared with chef or bconfig.

Also, for setups with small target VM's, it's increadbly handy to not have to install a bunch of stuff on each server and make sure it doesn't conflict with anything else.

But mostly it's that Ansible can be understood enough without devoting a couple weeks of your life to it. And you can come back later and understand what you have written.

- Super simple declarative yaml configs

- Agentless. You needed to have SSH working anyway so Ansible just uses that. With ssh pipelining it's so fast.

- The community support is huge and extensive.

- They have a module for everything and development is constant and active, much of which from the community.

- Hardware and networking equipment can be provisioned just the same as a VM or OS image.

The list goes on. Definitely give Ansible a try.

GauntletWizard 4 hours ago 0 replies      
This is pure bunk. Let's go down the list, one by one:

Maintenance:Sure, chef has a server component. So does ansible, if you're using it the way he suggests (with a host periodically running ansible playbooks on all hosts). Ansible has no client component to upgrade, though, so that's a win, right? It totally is, until Ansible doesn't work on a host and you can't figure out why, and the error logs you get are useless because some of Ansible's many assumptions about what the host's initial state is are incorrect. Chef can be managed by a standard package manager, which costs nothing on the client side, and allows far, far better assumptions to be made.

For the record, I eventually gave up on the chef server, replicated the playbooks to each machine (using a cronjob and git), and chef-solo.

Speed:Ansible pipelining speeds it up, significantly. You can almost get one command a second! Chef runs on host. It is ruby, and goes slow, but I have programmed a lot of chef and run a lot of Ansible, and my average chef run was under 30 seconds, and I've yet to have Ansible run any playbook in under a minute. Some of this is from atrocious default behavior, like requiring all hosts to complete a step before moving on to the next step on any hosts, or the fact that it spends nearly 10 seconds of cpu time on each machine 'gathering facts' at the beginning of it's playbooks, even if none of those facts are ever used.

Fact caching:This is a solution to the aforementioned problems with Ansible. It may make sense in the chef-server context, but I don't have a whole lot of experience with it.

Tags:This is probably a matter of personal preference, but I prefer to give the set of things that need to be done, and have the tree descend downwards based on dependencies from there. The author clearly prefers to specify with tasks when they should happen, and for each host a set of initial circumstances. This one can be argued til you're blue in the face. I make the point that there's a clear tree that can be built of dependencies under my scheme.

Push vs Pull:There's no maintenance cost to upgrading? What is this dude on? When you change Ansible revisions, you have to do just as much work adapting as from chef revision to chef revision. Ansible has always been highly in flux, and not great about not changing default behavior.

Pulls still have to be triggered, but they can (and should) be triggered on-host, in a cronjob. Your monitoring system should alert you when the chef run is out of date, though, honestly, if it is failing on just some of your hosts you need to clean up and unify your infrastructure.

Raw numbers:Ansible scales one large machine. Chef costs you a tiny amount on each machine. One of these scales. One of these does not.

Search and inventory:Oh gods, if you're using Ansible for inventory managment, please don't. If you're using chef for inventory management, please don't. Neither are reasonable tools for the job.

Orchestration:Neither chef nor ansible are appropriate tools for dealing with your application's data model. Full stop. Actually, full stop. There's nothing else of value further down this article. Please don't take any of it's advice.

I feel like no matter how Google or any other search engine ranked pages, SEO firms would be there to game the system and make a mess of the web. Making Pagerank visible to people with one particular toolbar does seem like a fairly major misstep on Google's part. The majority of the people who would really care about that are the kind of people you shouldn't be encouraging.

One of the obnoxious things about SEO is that if one person is doing it everybody has to do it. It's not necessarily enough to simply offer a better product at a better price. Luckily Google does try to reduce the effect of SEO. I notice for instance that StackExchange almost always beats out Expert Sex Change links these days.

There will always be people who want to game search engine results, regardless of how much information they know about their own standing, and the web was pretty much un-navigable pre-Google.

I first learned about this after starting https://neocities.org and seeing a bunch of really garbage pages that were full of random text that linked to a derpie site somewhere.

We get pagerank SEO spam from time to time, and it's pretty annoying. I have the tools to take care of it within 5 minutes every day, but I do worry that if we grow to a certain point it may no longer be possible for me to handle the problem alone.

I'm sure many other sites have similar problems with comment spam, and I'd love to hear some advice on how to deal with this from sites that have the same problem.

Right now our main lines of defense are a recaptcha (our last remaining third party embed, ironically sending user data to Google I'd rather not send to deal with a problem Google largely created), and a daily update of an IP blacklist we get from Stop Forum Spam.

I tried to do some Bayesian classification, but didn't make much progress unfortunately. And nofollow really isn't an option for me, as it would involve me manipulating other people's web sites and I don't want to do that.

Google joins Open Compute Project to drive standards in IT infrastructure googleblog.com

Finally, racks go metric.

The 19 inch rack is one of the oldest standards in computing. ENIAC used 19 inch racks. Open Compute, though, uses wider, and metric, racks. 19 inch rack gear can be mounted in Open Rack with an adapter.

The Open Compute spec says that shelves of IT gear are provided with 12 VDC power. There's power conversion in the base of the rack. Facebook has standards for distribution to the racks at 54VDC, 277VAC 3, and 230 VAC (Eurovolt). Apparently Google wants to add 48VDC, which was the old standard for telephone central offices.

Facebook's choice of 54VDC distribution is strange. Anyone know why they picked that number?

>Improved Java 8 language support - Were excited to bring Java 8 language features to Android. With Android's Jack compiler, you can now use many popular Java 8 language features, including lambdas and more, on Android versions as far back as Gingerbread. The new features help reduce boilerplate code. For example, lambdas can replace anonymous inner classes when providing event listeners. Some Java 8 language features --like default and static methods, streams, and functional interfaces -- are also now available on N and above. With Jack, were looking forward to tracking the Java language more closely while maintaining backward compatibility.

I also have similar experiences running ad budgets ($5M / month at highest). I built tools to do ad optimization on FB using attribution as a backbone and optimizing for ROI. I learned the hard truth with FB advertising when I built my own iPhone app last summer and thought all this experience would help me. Turns out when you're spending $2500 per day per campaign its easier to sit back and optimize, but when you're spending $100 in a month its completely different.

Turns out that the first thing you need to do is figure out if FB is the right channel for you. I found out that on FB, anyone will download anything that looks interesting and you can optimize your CPI fairly easily. But if you count on people spending money via in app purchases, the typical rules (1%-5% of active users) don't always apply for apps of different genres.

shostack 8 hours ago 2 replies      
The bit about attribution is critical, but misses a more important basic piece which is "make sure you setup and properly QA your conversion tracking."

So many companies launch FB ads without proper tracking and then are surprised when they have no idea what it did for them. FB tends to group everything under the sun as "engagement" and "conversions", so really digging in and understanding those settings is key.

For example, 1-day view-through credit by default is probably a bad idea for many advertisers, particularly when you have no clue what the quality of a view-through is, and what they are worth to you. They are VERY different in terms of value, but FB wants to give them 100% credit with their rules within 1-day. That's simply not how most savvy people approach attribution.

Google Analytics offers some great basic attribution tools out of the box that let you experiment and compare different static models, or create your own static model. Ultimately static models themselves have inherent limitations because attribution is a much more dynamic thing that exists at the individual user path level, but it is a great start.

As much as like I EFF's coverage in general:

> And we will continue to press our partners to allow digital information to cross borders unimpeded. We are working to preserve a single, global Internet, not a Balkanized Internet defined by barriers that would have the effect of limiting the free flow of information and create new opportunities for censorship.

This is technically correct. It doesn't create new opportunities for censorship. These opportunities always existed.

> The TPP illustrates these shortcomings well. Its free flow of information rules would only be enforced for foreign enterprises, and only those entities based out of countries that have signed the TPP. So if a country were to enact a law banning some type of online content, the TPP's free flow of information rules would do nothing to prevent the enforcement of that censorship against websites or platforms that are locally-owned in that country.

Yes and nothing prevents that already. The TPP doesn't alter the sovereignty equation, it is a trade treaty.

The TPP makes things worse but such weak attacks against statements that are technically correct are largely ineffective.

Posts like these are much more effective as they show legitimate problems that could have been resolved favorably (for the general population) in a trade treaty:

Is a modal editor better? Should key bindings be built around a more efficient keyboard layout, like Programmer Dvorak, for example?
