Barrett Brown was not convicted merely for linking to data on the web. He was convicted for three separate offenses:

1. Acting as a go-between for (presumably Jeremy Hammond) the Stratfor hacker and Stratfor itself, Brown misled Stratfor in order to throw the scent off Hammond. Having intimate knowledge of a crime doesn't make one automatically liable for that crime, but does put them in a precarious legal position if they do anything to assist the perpetrators.

2. During the execution of a search warrant, Brown helped hide a laptop. Early in the trial, in advancing the legal theory that hiding evidence is permissible so long as that evidence remains theoretically findable in the scope of the search warrant, Brown admitted to doing exactly that, and that's a crime for the same reason that it's a crime when big companies delete email after being subpoenaed.

3. Brown threatened a named FBI agent and that agent's children on Twitter and in Youtube videos.

The offense tied to Brown's "linking" was dismissed.

Brown's sentence was unjust, but it wasn't unjust because he was wrongly convicted by a trigger-happy DOJ; rather, he got an outlandish sentence because he managed to stipulate a huge dollar figure for the economic damage caused by the Stratfor hack, which he became a party to when he helped Hammond.

I don't understand exactly why it's necessary to release usernames along with the passwords, or why it's ethical to do so. Stripping the domain portion of email addresses does absolutely nothing when you can find the real email, and other accounts of the victim, by Googling the unique part of the email address.

How does tying each password to its corresponding username help with password research, and does the value gained outweigh the cost of someone using this list for malicious purposes?

I'm not saying this should be illegal, but I'm struggling to understand the intent here.

It was a mistake to release this today.

Everyone knows that legally questionable moves should always be made on a friday. That allows everyone in government to cool down for a couple days. By the time the weekend is over all the news outlets have moved on to whatever war just started up. You don't want some hothead prosecutor tweeting out a threat, forcing himself to follow through later in the week. Nobody picks a fight when 15 minutes away from a weekend.

Watch the NSA/CIA/MIB admissions. They always stage their spying/torturing me culpas on friday afternoons.

Forgive me for doing so, but allow me to ask some possibly ignorant questions and perhaps play the devil's advocate for a moment. What about this release will help? What are the compelling research problems in the space?

We know users pick bad passwords. It seems to me the most compelling "problem" is hardly a research question -- isn't it about finding ways to encourage users pick strong passwords, not share them between sites, and not put them on sticky notes on their monitors.

Ok, putting my charitable hat again... My best guess is that researchers would like some idea about how long it takes to crack some percentage of accounts; e.g. with rainbow tables or other techniques?

The author mentioned "Analysis of usernames with passwords is an area that has been greatly neglected and can provide as much insight as studying passwords alone." What directions might a researcher take this?

srcole 34 minutes ago 0 replies      
What sorts of analyses are you guys planning? Maybe:-clustering of passwords. are aspects of the username biased towards certain clusters?-distribution of alphanumeric characters at each position of a password (e.g. 1 is a disproportionately common final character)-differences in password strength between usernames with male and female names

There is an annual 'Passwords' conference [1], which I attended in 2012, and was blown away by quite how much researchers are able to do with these password lists.

Unfortunately, I was equally impressed with what attackers are able to do with them as well. An important point is that attackers tend to have better lists, because they are the ones stealing and cracking them, and these lists make them increasingly better at cracking passwords. Defenders use the lists for all sorts of analysis on how exactly users pick passwords.

For example, "complex password policies" have become increasingly popular. But do they actually increase the entropy of the chosen passwords? Surprisingly little, since users will "defeat" the policy by applying easy to guess "munging rules". Humans being human and such. The thieves have the lists, and learn to apply the munging rules and defeat the policies. Researchers need these lists so they can discover the same weakness and try to react.

More recent research looks at things like how effective the password strength indicators are at actually helping users choose stronger passwords. We also learn about how users choose different strength passwords based on the sites they visit and such. This is absolutely fertile ground for research which can improve how we perform authentication.

Yet another good use of the lists is in defending against online attacks. E.g. Failed attempts that follow the general probability distribution of the lists are easier to identify as bots.

[1] - I think all the talks are posted, although I'm not sure there's a central archive, each conference is identified as Passwords^[Year], e.g. Passwords^14 https://passwordscon.org/

When I first got on the Internet in 1994 I used the same password for everything for the next decade before I became security conscious (now I have a random, strong, unique password for every service).

Anyways, that password is not in this list. I have found it in other password dumps before. So, I don't know what to think.

From the law quoted in the article, wouldn't it be illegal to simply make a course about computer security?

The teacher willfully (and knowingly) teaches the student about "possible means of access to a protected computer."

Note: According to http://www.law.cornell.edu/uscode/text/18/1029 teaching is defined as trafficking information ("the term traffic means transfer, or otherwise dispose of, to another, or obtain control of with intent to transfer or dispose of; ")

Even if this release has no implications for security, I think it may raise legitimate concerns for users' privacy. No doubt most users expect that their passwords will be known only to themselves. Many of the usernames contain real names, and many more could probably be traced to them. Ian Watkins was found to have "gloated" about his crimes in his password. With time and attention, I wonder whether such "dark secrets" could be found in this list.

I thought of exactly the same. I was motivated by the password strength meter out there. How can you actually tell a password is strong or not or whether a password is known to attacker or not if you can ask (I was thinking along the line of private information retrieval) privately and get a probability rather than a yes/no based on all the known stolen credential out in the Internet (there are many Gbs files you can download)...

This is great, but if you use a password manager, it's very difficult to determine which, if any, of your accounts would be compromised. For myself, this would just be doing a dump and looping a few greps. But for family and friends, does anyone have any ideas for a less technical audience?

Has modern Linux lost its way? Some thoughts on Jessie
points by fpgeek  3 hours ago   41 comments top 13
geofft 1 hour ago 5 replies      
If you're running an up-to-date GNOME/KDE/etc. desktop, and not running systemd, for better or worse you're using a less-supported configuration. There's going to be other stuff that systemd will break, but in the long run you're better off using the upstream-recommended configuration.

That aside... I think it's pretty clear that modern Linux is not losing its way. If you go back even five years, and complain that your latest pre-release version of Debian won't suspend properly because it needs a password, you'll get laughed at by all the people who try to suspend their laptop and have it crash in some way or another.

We're now in the uncanny valley of software progress. If suspend weren't working, you'd feel hardcore and learn it and deal with it. If it worked perfectly, then you wouldn't think about it. (What was the last time you thought about how OS X or Windows does suspend, or handles permissions on mounted drives, or whatever? When was the last time you read a manpage about launchd or one of its helpers? Hint, the manpages are useless.) If it has almost all the complexity to work perfectly, you get neither of these benefits.

But it would help things immensely if someone were to document all this, from a busy sysadmin's perspective, not from an upstream developer's. There are occasionally manpages, but they're written like git's. Lennart's "systemd for administrators" series is a start, but that's more of a pitch for why you should want to build your new systems on it, and it only covers systemd. Docs on how to figure things out when they go wrong would be most useful.

I've been having similar issues and thoughts. I'm not a greybeard by any reasonable measure, having started using Slackware in '99-'00, quickly switched to Debian, and never looked back.

I think it all stems from D-Bus, which has become the primary mechanism of command and control on desktop Linux. To address the OP's initial issue of user mounting disks, it's managed via Udisks, which is mostly accessible via D-Bus.

I have trouble reconciling Unix's notion of "everything is a file" and how a modern Linux desktop operates via D-Bus. Don't get me wrong, I think D-Bus very powerful and flexible. I just wish it was easier to explore and test via file-based tools. Maybe a FUSE layer?

Anyhow, if the OP thinks that Linux was once "clean, logical, well put-together, and organized", I can only laugh at his rose-colored glasses. Linux is and always was a cobbled-together mess of orthogonal paradigms (no better illustrated than by the design philosophy clash of XWindows vs Unix). Maybe earlier Linux was simpler because it was still playing catch-up with other Unix clones out there. Nowadays it's leading the pack in innovation, and so things are changing, and fast. I don't know if documentation really is worse now that it used to be, I'm afraid to fall in the same nostalgia fallacy.

Ultimately, I see this rant as nothing other than "things are different now and I'm scared and confused". Not that I don't sympathize, being in roughly the same place. However, I decided I can't stop technology, and sucked it up and sharpened my google-fu.

The traditional user/group system may be simple, but it is limited. For example, it fails when you have a multi-user desktop system when some people login in locally, and some people login in remotely. What should the permissions on on the camera be? And what about hotplugged USB devices? It's no longer possible to have a fixed device node with fixed permissions and fixed user group membership.

The same applies to suspend. The local user perhaps should or should not be able to suspend the machine. Presumably remote users should not be able to do so at all.

What about wireless network connectivity as the machine moves? Who should have permission to manipulate that?

If we did not have more a more complex dynamic permission system[1], some would be saying that modern Linux is outdated and unable to cope with the more modern reality of much more dynamic needs like this.

Instead, the article seems to be saying that it's become too complicated.

We can't have it both ways.

I think it is a old-timer issue. I'm using Linux on my desktop for ca 15 years. I also had a mysterious permission problem after my last Ubuntu upgrade. In contrast, to 10 years ago, I do not like hours of debugging to get USB working anymore. It was fascinating then.

For the record, my permission problem was solved via "sudo pam-auth-update --force". Thanks Arch Wiki for giving me the crucial hint.

I used to be able to say Linux was clean, logical, well put-together, and organized.

I don't think this was ever really the case, but I do think software is evolving to meet the list of constantly updating use cases.

Of course managing one network interface with all your peripherals connected at startup required less complexity. But if your target audience also has use cases of wanting their USB drive to "just work" when plugged in, being able to connect to a new wifi access point under their normal user, etc., you will want some extra layers of abstraction that aren't available if you limit yourself to FDs and Unix-style permissions.

In addition, some software is cross-platform and doesn't always care about maintaining consistency with the conventions on a single platform.

I don't think speaking about "modern Linux" and then referencing one user's experience with one distribution is indicative of the entire movement.
aceperry 1 hour ago 2 replies      
It's funny to hear the the name Debian associated with the label "modern." I don't mean to diss Debian, it's a solid distro and has a lot going for it, but it is seriously behind all of the cutting edge distros that I'm used to.

Personally, I enjoy new technologies and systems in linux. I used to run Gentoo and other distros that constantly brought out cutting edge software. And I'm used to somewhat alpha/beta quality software that mostly works. And because it works well compared to my experience with windows software, so I wasn't too bothered.

Maybe it's because my background is in hardware, but all of the new software had always taken awhile for me to grasp and appreciate. But in the linux community, I've always been able to find info and solve problems that I've come across and learn about the system. Windows problems usually can be solved because large masses of people tried so many things, but I wouldn't get any enlightenment about computers or software when fixing Windows problems. Maybe my world view has been skewed by comparing linux to windows, but I've always felt that I'm able to learn and understand more with linux vs Windows.

Relevant quotes for TLDR:

"It worked, but I dont know why"

"I dont even know where to start looking."

"Thats about as comprehensible as Vorlon poetry to me"

Potentially non politically-correct answer to the article title: maybe it's not Linux who lost its ways, but some old-time users? (who forget the beginner's spirit to look for answers on forums, manuals, to try to understand before casting a judgment)

Linux has always innovated around the paradigms, taking inspiration from everywhere. It was never "clean, logical, well put-together, and organized". It has always been messy, but in a good way.

When I first discovered linux, I had to adapt to all these new things. That was in 1992. When I decided to use again a modern linux distribution on my laptop in 2014, I had to adapt - again. I have no doubt I will have to keep adapting in my lifetime.

The error would be to consider that the "right ways" are fixed, and that innovation should be stopped.

There will be many new things, some will be kept, some will be discarded. Change is the only thing one can constantly bet on.

$500k of Azure credit for YC startups

mbesto 10 hours ago 5 replies      
Microsoft is also giving YC startups three years of Office 365, access to Microsoft developer staff, and one year of free CloudFlare and DataStax enterprise services.

Free Office365 and CloudFlare are probably the best part of this announcement, since they are "easily migrate-able" by most startups. Migrating from DO/AWS/Linode isn't fun and productive. Even though they are negligible (in terms of money and value) they are the easiest "sticky" points for early stage startups.

That being said - for DevOps people with experience across AWS/DO/Linode and Azure, this would be a good time to start the cold calls and sell your services to YC companies. Paying someone $5-10k on high ($2k/month) AWS bills to free services is a no-brainer.

EDIT: On that note, if any DevOps people want me to do the hustling (aka sales, lead generation) for them, let me know.

EDIT2: Anyone know if the $500k goes for 3-years? If it's only 1-year, then this may not beat the 1-2 years and ~$10k you get from Amazon via their platform: http://aws.amazon.com/activate/portfolio-detail/

Free stuff is great but I wonder if there'll be any subtle nudges to use this for the next badges. "Your hosting estimates seem high, why don't you just use Azure"? "Well we considered it but long term we'd rather use another hoster for reasons X,Y,Z"..."Well yeah but 500k more runway is a lot."

I'm probably worried over nothing since YC investors are smart and tend to leave tech choices to the founders but I'd like to hear some feedback on this from people that pitch in the future.

Either way Microsoft seems to make pretty good decisions lately (from my humble POV). Seems like they are essentially playing the same power law as (other) investors, hoping that the next XXX will be run on Azure.

On a somewhat realted note...I worked in IT in Africa for a bit and it was pretty strange how locked into Microsoft server stuff they (Africa is big but it was true for all countires I had work relations in) are. I naively assumed that Linux/BSD would be more wide spread there but my very subjective conclusion is that MSxx-certificates are really widespread there and piracy is kind of tolerated so it's easy to learn. It was a little bit harder than expected to find Linux admins for example. I've always wondered if this was active corporate policy or just an "accident".

Great offer.

I was accepted into Microsoft's BizSpark program last year so I get $150/month free Azure credit. Azure is very nice to use. So far, I have just been using Ubuntu Linux VPS instances (similar to AWS EC2) and everything works similarly to other providers I use like AWS, IBM BlueMix, Digital Ocean, and Google's cloud services. Really, these are all very good services, so use the one you can get for free or at a low cost.

I used to be pretty much down on Microsoft, but now they are doing a lot of stuff right in my opinion: providing solid Linux support on Azure and providing an unbelievably good deal on the family edition of Office365. It seems like they are buying themselves into the cloud market, but with all of their cash on hand, that seems like a good strategy!

Anyway, if you have a business idea you want to try then look into BizSpark.

How long do companies have to utilize the $500K?

In the BizSpark Plus days, your company would receive $60K of hosting but could only use it to pay 100% of your bill in the first year of BS+. In the second year, you could use it to pay 50% and then in the third year you were paying full price for Azure. It was a pretty good deal, but if you are already spending $30-60K (or $250-$500 K) on infra in your first year or two, you're in a select breed of companies.

Azure has been great for our start-up (http://iactionable.com). We've been with them for over 4 years. There have been ups and downs but we're fans of C#/.NET and it was a great fit for our team. We store and crunch a lot of real-time data with ServiceBus Queues and SQL Server. It has scaled well so far. We also went through the BizSpark program which REALLY helped jump start things.

We were invited up to Redmond in the past to meet with teams from various Azure services and participate in private previews of some cool features. They're really working hard to make a great platform.

This is a smart move for Microsoft. Most companies will not utilize the credit, a few will use some but not all of the credit, and there will probably be one or two breakout companies from the batch with huge computing costs. If they snag one of these breakout unicorns, $500K in free computing is a reasonable expense.

This is huge for Microsoft, because this is how Azure is finally starting to get accepted by the startup/VC community. They never had difficulty selling Azure to the enterprise, but for startups - AWS had always been the default choice.

This seems like a Catch-22. If a startup is successful enough to get into YC, wouldn't they have a stable tech infrastructure already?

This would only benefit YC startups who already use Azure. (Unless the switching cost from AWS/Rackspace/Google is low enough nowadays.)

I'm not sure how Azure intends to compete in this space. I've used Amazon, Rackspace, Google Cloud, Azure, and a bunch more.

Professionally, for simplicity I'd choose Rackspace or Google. For Scalability and price I'd choose Amazon. For personal projects I love Digital Ocean.

I dislike Azure's control panel and VM setup, and find their VMs slow. I'd only really consider them if I planned to implement a project that required leveraging the entirety of the Microsoft technology stack.

I can't see technology companies embracing Virtual Windows Server RTs and MSSQL Servers. Startups enjoy technologies that are easy to manage and scale with smaller teams. Enterprise level companies still need inhouse dedicated hardware for security.

Azure is kind of an oddball in the virtual hosting space.

If Microsoft truly wants to transform they need to launch an intensive secret project. Let's call it "Project Redmond". The goal of the project would be to develop "Quantum", the next Microsoft OS. Quantum aligns MS with Linux by effectively building Windows on top of Linux as well as all the tools necessary to, as automatically as possible, migrate existing Windows code into Quantum.

With a move like this Microsoft becomes THE Linux company as the millions of non-tech and tech businesses who are Windows based migrate to Quantum over time. They could make the underlying souped-up Linux OS FOSS and sell the Quantum OS layer (or whatever works).

I am thinking in terms of the next 50 years, not 5. In the long term I just don't see how the existing MS model can prevail. A move like this Quantum OS concept would instantly align them with web development and provide a solid alternative to Apple on developers desktops and perhaps even Ubuntu at the server level.

> Its easy to get enough rest if no one else wakes up early and the village goes dead during afternoon naptime. It helps that the cheapest, most accessible foods are also the most healthful and that your ancestors have spent centuries developing ways to make them taste good. Its hard to get through the day in Ikaria without walking up 20 hills. Youre not likely to ever feel the existential pain of not belonging or even the simple stress of arriving late. Your community makes sure youll always have something to eat, but peer pressure will get you to contribute something too. Youre going to grow a garden, because thats what your parents did, and thats what your neighbors are doing.

Great article. This importance of pervasive cultural factors was the key insight for me. I follow an unusual diet that happens to consist of 100% unprocessed foods. I allow myself to sleep when I'm tired. I live somewhere I can enjoy long walks and other fun exercise. I'm never late because I don't set schedules.

> In the United States, you cant go to a movie, walk through the airport or buy cough medicine without being routed through a gantlet of candy bars, salty snacks and sugar-sweetened beverages. The processed-food industry spends more than $4 billion a year tempting us to eat. How do you combat that? Discipline is a good thing, but discipline is a muscle that fatigues. Sooner or later, most people cave in to relentless temptation.

This is the trouble with following a different lifestyle; almost every aspect of it conflicts with modern culture. Buying vegetables at a store, there's tasty frozen pizza across the isle. Going out with friends, for variety and a normal social atmosphere, modern-influenced food is the only option. Walk into a gas station and there's the chips. Look at cat pics on the internet and there's pictures of beer and bacon. Everyone wants to set a schedule, out of habit if not the belief that stress increases productivity. People call to talk late at night.

Even after forming good habits, every instance of conflict with the culture requires some willpower, and socially, each requires an explanation. The only way I've succeeded is when living a more isolated lifestyle, somewhere remote. That leaves out cultural enjoyment and reinforcement.

I got a copy of Paul-Henning Kamp's critique "HTTP/2.0 - The IETF is Phoning It In" off the ACM website before the link went dead. Here's a bit of what he said about it:

"Some will expect a major update to the worlds most popular protocol to be a technical masterpiece and textbook example for future students of protocol design. Some will expect that a protocol designed during the Snowden revelations will improve their privacy. Others will more cynically suspect the opposite. There may be a general assumption of "faster." Many will probably also assume it is "greener." And some of us are jaded enough to see the "2.0" and mutter "Uh-oh, Second Systems Syndrome."

The cheat sheet answers are: no, no, probably not, maybe, no and yes.

If that sounds underwhelming, its because it is.

HTTP/2.0 is not a technical masterpiece. It has layering violations, inconsistencies, needless complexity, bad compromises, misses a lot of ripe opportunities, etc. I would flunk students in my (hypothetical) protocol design class if they submitted it. HTTP/2.0 also does not improve your privacy. Wrapping HTTP/2.0 in SSL/TLS may or may not improve your privacy, as would wrapping HTTP/1.1 or any other protocol in SSL/TLS. But HTTP/2.0 itself does nothing to improve your privacy. This is almost triply ironic, because the major drags on HTTP are the cookies, which are such a major privacy problem, that the EU has legislated a notice requirement for them. HTTP/2.0 could have done away with cookies, replacing them instead with a client controlled session identifier. That would put users squarely in charge of when they want to be tracked and when they don't want toa major improvement in privacy. It would also save bandwidth and packets. But the proposed protocol does not do this.

[He goes on to tear a strip off the IETF and the politics behind HTTP/2.0 ...]

HTTP/2 might have version 2 syndrome.

Another better way would have been keep SPDY, as there is usefulness there, separate and then on HTTP/2, to incrementally get there, and use an iteration of something like AS2/EDIINT (https://tools.ietf.org/html/rfc4130) which does encryption, compression and digital signatures on top of existing HTTP (HTTPS is usable as current but not required as it uses best compression/encryption currently available that the server supports). This standard still adheres to everything HTTP and hypertext transfer based and does not become a binary file format but relies on baked in MIME.

An iteration of that would have been better for interoperability, secure and fast. I have implemented it directly previously from RFC for an EDI product and it is used for sending all financial EDI/documents for all of the largest companies in the world Wal-mart, Target, DoD as well as most small and medium businesses with inventory. There are even existing interoperability testing centers setup for testing out and certifying products that do this so that the standard works for all vendors and customers. An iteration of this would have fit in as easily and been more flexible on the secure, compression and encryption side, and all over HTTP if you want as it encrypts the body.

HTTP/2 is an ugly mess of taking something simple and making it more complex for minimal benefit. It could have been so much better than a binary mess.

As engineers, the ones that take simple concepts and add complexity, those are not engineers, those are meddlers.

It could be as long lived as XHTML.

I was hoping for more SCTP rather than a bunch of cludge on top of what is a pretty beautiful protocol in HTTP 1.1. Protocol designers of the past seemed to have a better long view mixed with simplicity focused on interoperability that you like to see from engineers.

As it's already written in the manual...


wordexp, wordfree - perform word expansion like a posix-shell

So, the implementer decided to take the short route, and just spawn a shell which, essentially, gets passed the input data to wordexp(), to do the work. But, of course, having something that starts with such a comment...

/* XXX this is _not_ designed to be fast (...) wordexp is also rife with security "challenges", unless you pass it WRDE_NOCMD it must support subshell expansion, and even if you don't beause it has to support so much of the standard shell (all the odd little variable expansion options for example) it is hard to do without a subshell). It is probably just plan a Bad Idea to call in anything setuid, or executing remotely. */

...in your standard C library wasn't such a smart idea to start with. Scroll down, there are many more gems in the comments!

Sometimes it's better to just implement it as

        void wordexp() {                fprintf(stderr,"wordexp() is a security nightmare. Not implemented.\n");                assert(0);        }
or decide to deliberately only implement a safe subset of the full functionality specified (e.g. only ~user-homedir expansion and $VARIABLES), to at least cover the common use-cases without creating a security nightmare.

Last I heard, Hematite was more of a Rust-based renderer of Minecraft worlds than an actual game. For example, I don't think it currently supports construction or destruction of blocks.

Piston, the project that's backing Hematite, is very interesting in that it's an attempt to explore idiomatic approaches to game engine design in Rust. I'm not sure how many game developers will value Rust's memory safety over C++'s sheer flexibility and mature tooling, but I commend the Piston developers for taking a chance on a new and unproven language!

EDIT: If you'd like to take a closer look at game development in Rust, be aware that there exist dedicated communities for this on reddit ( http://www.reddit.com/r/rust_gamedev ) and IRC ( http://client01.chat.mibbit.com/?server=irc.mozilla.org&chan... , a.k.a. #rust-gamdev on irc.mozilla.org).

This is a really interesting idea, though maybe a bit too expensive and, ah, "hip" for my tastes. (Currently hopping from Airbnb to Airbnb flatshare, paying $1000 or less a month for housing with internet and utilities included. Would be even cheaper if I wasn't in Western Europe.)

I've been thinking lately of where I would like to live for most of my late twenties and early thirties. I'm definitely a bit of a loner, but at the same time, I like living as part of a close-knit community. I wish I could find a little "tribe" of self-directed folks roughly my age in an old, creaky house somewhere in the mountains... or on a remote island... or in a forest, or something. Just people working on their projects, tending to their garden, raising some chickens (or maybe some kids), enjoying the fresh air, and mostly living away from the rest of society. An art commune for the 21st century, I guess.

Unfortunately, if such a place exists, I doubt it has a website, and I especially doubt they'd take in strays. Guess I'd have to organize it myself. It's too bad I don't know anyone else who'd want to live like this. (And even if I did, who knows if we'd get along?)

Maybe I'll just go and become a hermit.

> Of course, at some level this isnt very different from what compilers have been doing for ages, if we consider the source language program to be the specification, but when were doing synthesis the connotation is that the specification isnt directly implementable using standard compiler techniques.

I guess compiling lazy functional languages was synthesis at one point, too, before people really figured out how to do that efficiently via eg the tagless spineless g-machine.

I wonder whether synthesis is like AI: whenever we understand how to do something, like play chess, it's no longer AI.

> Mathematics has no side effects.

I'm aware the author is a professor of CS, but this is a statement I always see people originally trained as programmers claim, and as a mathematician and a programmer I respectfully disagree.

Mathematics does what you define it to do, and if you can communicate your idea to another person it doesn't matter whether you "mutated" a variable or not. Likewise, you could say that there's no such thing as mutation in programs because the value of a variable in a language that supports mutation depends implicitly on time; you just don't express that in the source code. It's a matter of perspective, and more perspectives are often better than fewer. In math if you want to index a variable to have "pretend mutation" to avoid confusion you can, but there's no rule about it. If you feel the best way to communicate that idea is with mutation, then that doesn't stop it from being mathematics.

    public Node(SortedSet<T> left, T element, SortedSet<T> right) {      this.left = left ;      this.right = right ;      this.element = element ;
Isn't really mathematics. Nodes have a label. Any record attached to the node is business logic. It doesn't matter if the tuple is (first, last, address, department) or (value left, right), these are not part of the mathematics. Sure (value, left, right) looks like math, but it's just a convenient place to cache the edges describing a particular form of graph.

A graph is defined mathematically G = {V, E}. A single vertex with no edges is a graph. A set of vertices with no edges is also a graph. These may or may not be interesting, but edges are dependent on vertices. The converse is not true.

This example with Node(value, left, right) is standard object oriented fair. It's worse than Car(model, manufacturer, color, year). The Car simplifies something complex. Node(value, left, right) makes something simple more complicated. It's an implementation not an abstraction.

The article doesn't mention matrices, which map to multidimensional arrays. One of the basic features of FORTRAN, all the way back to the original version for the IBM 704 in 1954, was multidimensional arrays. Yet C, C++, Go, and Rust all lack them. They all have "arrays of arrays", or some hack involving macros and templates and a multiply for every array access.(Yes, there's a sort of multidimensional array capability in C99, but it is not used much.)

For Go and Rust, this subject has been discussed.[1][2] In both cases, the participants in the discussion got tangled up with how slicing syntax would interact with multidimensional arrays, and ended up doing nothing.

The number-crunching community is mostly using Matlab/Octave, and Python with NumPy.

This isn't really too surprising; this is the kind of problem you have when you try to automatically enforce real name policies.

Google+ had similar problems, if I remember right, and they ultimately solved the problem by getting rid of the real name policy entirely.

A Coq development of a theory of lightweight cryptographic ledgers
points by kushti  13 hours ago   4 comments top 3
socrates1024 6 hours ago 0 replies      
I wrote a paper called "Authenticated Data Structures, Generically" [1] that's closely related to this. It shows how to automatically make a "merkleized" version of any (pure functional) data structure. The original motivation (and a case study in the paper) is making Bitcoin verifiers that don't require much storage, similar to this.

I don't fully understand the compact tree proposed here. I used balanced red-black trees, and others have suggested tries since the element size is fixed (160-bit address, or 256-bit tx hashes). I think you're basically proposing a trie. It would be possible to make invalid addresses that incur the worst-case cost to check (00001, 00002, 00010, 00020, and so on) but this is maybe splitting hairs.

Anyway, this is awesome to use Coq for formal verification of cryptocurrency components. We need way more of this.

It makes more sense if China wants to protect the Chinese consumer.

No, it doesn't. Just like every other neoliberal economy out there, since when has China's government started caring about the consumers?

The Chinese government is "punishing" Qualcomm for monopoly, yes, but it has nothing to do with the consumers.

"fueling concern that the country -- the worlds second-largest economy -- is using such inquiries to boost its native enterprises."

No shit. Look at all the local clones/"competitors" that have started doing very well after the original companies have been eliminated from the market (Google, Dropbox, just to name two obvious cases).

It's all about lobbying, the kind that you don't find in public records - i.e. bribing and corruption.

Odd that they state that "For handsets sold in China, Qualcomm will charge a licensing rate thats similar to the royalty rates it charges elsewhere in the world, countering concerns that it would be forced to offer a discount to settle the investigation."

And then immediately follow with "While the percentage being charged is similar, the value of the handsets -- used as the basis for the calculation -- will be assessed at 65 percent of the devices total price for phones sold in China, Qualcomm said."

If read right, that means Qualcomm is forced to effectively discount licensing fees in China based on this decision, meaning the Chinese government has engaged in a bit of price-fixing relative to the rest of the world on the patent fees.

But it has happened so drastically that there is no way to find out what it costs, "contact sales" is the answer but no response from them yet. It was very rushed see here: https://developer.vuforia.com/forum/vuforia-40-beta/prices-a...

My experiences through GrubHub's IPO from start to finish
points by dmarinoc  16 hours ago   46 comments top 6
ilamont 3 hours ago 2 replies      
If everything goes perfectly and the company has created a lot of buzz and momentum, there is interest to buy at a price above what has been printed on the S-1. As the pricing approaches, the company responds to this interest by increasing the price. Then the investors respond to the new price. This cycle repeats two to three times as the date approaches.

So, the price was not based on fundamentals of the business, but rather buzz, hype, and tactics like restricting the number of shares. The common stock price has since risen but it's now running a P/E ratio of 135 (1).

Who is getting the short end of the stick when reality kicks in? Mom and pop investors? Mutual funds and pensions?

Also, what's with the "bootstrap" banner at the top of the page? Grubhub took $84 million in funding (2).

If your company goes public and you have valuable equity but face a lockup of 6 months you can still "lock in" some price...if your company gets publicly traded options that is.

Sell calls at the price you want to sell for the month that the lockup expires. If your shares get called away you got the price you wanted and some premium. However, you miss out on a huge gain if it goes far beyond your call level. Also, if the stock tanks in that time you keep your now less valuable shares but you got some premium.

So, after selling calls you can take that money you made from the premium and buy puts with it at around the same price. You've created a spread here and have locked in a selling price and gave yourself some downside insurance - all for very little cost to you over all since the covered call premium paid for most, if not all of your puts. Your only risk now is that the stock goes through the roof and you miss out on some upside - but that makes sense as you've eliminated risk for very little out of pocket cost. So maybe you do this on 1/2 or 2/3 of your position or whatever you're comfortable with.

Of course the difficulty is if you have a ton of stock and the option market for your company isn't very large and therefore illiquid.

at least in CA (and majority of other states) the requirement is only 1 year of post-med-school training:


" How much training must I complete before I am eligible for licensure?

A US/Can must complete 12 continuous months of training in a single program to be eligible for licensure. Further, a US/Can must be licensed by the end of the 24th month of training. "

So going into 3rd year of residency one must already be licensed.

The rest of states:


Note: That is not to dismiss the importance of residency. As one can see from the above, its importance goes way beyond of just getting the license.

The "matching program" isn't new--goes back to the 60's if not further. Sounds like the idea hasn't changed even if the "algorithm" is machine-implemented in recent times, no surprise there.

Used to be the student would put on his/her list the residencies in order of priority, and so would the institutions rank the candidates. Let the matching begin!

A thing to note is that not all residencies were in the mix and there were always a good number of students who weren't selected or maybe didn't even participate. That left room for students to find vacancies to fill.

AFAIK there weren't any students who couldn't get into a residency somewhere even if not among their top choices. Besides by the end of the first year of training there were always plenty of residents shifting to other programs so "holes" migrated around to an extent.

Chances are the situation is not at all dire for the current crop of graduating medical students. It tends to all work out.

I remember playing Star Trek on HP teletypes connected to the Peoria mainframe in the high school math lab. Jeez we burned through a lot of paper.

A friend modded a version to automatically fire photon torpedoes when you entered a sector with Klingons. It calc'd the trajectory so it never missed.

Of course the downside was the blow back if you shot one right next to you. Or if there was a star in the way. Or there were >3 Klingons that would hammer you while the computer is cycling through the auto firing sequence.

I was on the team that won the shredder challenge. I talked to one of the UCSD people afterwards and he practically convinced me that my team did it. After a while I realized that it was so damn easy to sabotage their effort that I didn't really care if my team did it because that's what happens when you invite the whole internet to your party. Now I guess they managed to clear us of that. :) Unfortunately, when this Adam guy wrecked their program, he wrote them a letter which simultaneously implied that he was our team and the group "Anonymous" at the same time. Some people at DARPA seemed to believe that claim (even though I used my real name to sign up) and so DARPA was very hesitant to announce that we had won the competition. It was a fun competition though.

If you think about it, corporations are essentially crowd sourcing machines with sophisticated recruiting, hierarchies, regulations and rewards. One could say that corporations are on the far right of the spectrum while the contest itself with minimal rules, regulations and vetting for participants is at the far left.

Which is more efficient Corporations or crowd sourcing? Perhaps the sweet-spot is somewhere in the middle. Just add some rules and structure for vetting the players or distinguishing the saboteurs and maybe it might work!

Learning Smalltalk from Pharo by Example

As a diehard functional programmer (who used to shun OOP as a fad) who's been dabbling with Pharo over the last few weeks, I must say I'm impressed. And, like the article pointed out, I'm having the same "seeing the light" experience that I first had with Lisp and Erlang.

After experiencing what OOP is really all about, an interactive environment with live objects sending messages to each other, readily available to be inspected and manipulated [0], I find it a drag to go back to Python and Clojure (less so) on my day job.

I now feel like every other OOP implementation (without the live environment) is just a horrific bastardized version of Smalltalk.

Going through Pharo By Example, and especially the similar book "Dynamic Web Development with Seaside"[0] (a smalltalk web framework), really helped me to understand many concepts in OOP. Seaside is worth checking out simply for how differently it does things (the author describes it as a "heterodox" framework). As others have said, once you experience the joy of the flow of programming in Smalltalk with a great environment, it's difficult to not miss it when using other languages.

Edit: Actually, I guess some of the things done in Seaside are now more common, such as building up a webapp from reusable components that have code and some local state coupled with a view.

Last year I added a touch of programming to my 9 year old son's home school activities. We tried several learning tools, starting with Scratch. I don't have anything negative to say about the various options we tried. However, the most positive exercise was him going through the "Prof Stef" tutorial built into Pharo. He really got into exploring and interacting with objects using tradition Smalltalk inspectors and workspaces (Do it, Show it, Inspect it). He loved that he could close the environment and open it the next day with all his play right where it was.

As a father, I loved that I didn't feel like a fraud as I could easily help him dig around and answer just about any question on what's really going on.

Filenames and Pathnames in Shell: How to Do It Correctly (2010)

Today I learned globbing happens after word-splitting.

Can someone explain the following:

   for file in ./* ; do        # Prefix with "./*", NEVER begin with bare "*"     if [ -e "$file" ] ; then  # Make sure it isn't an empty match
1. Why prefix with a "./" ? Is that just to help avoid the `cat $filename` scenario? (i.e., that $filename will be "./-n" instead of "-n", and that

  cat -- *
is perfectly valid?)

2. What's the -e check for? It says "an empty match" -e means that the file exists, but * would only return files that exist, so -e must (with some caveats) be true. (The caveat being that there's a race condition between the globbing and the test, but with the added test, there's _still_ a race condition between the glob, the test, and the command execution. Are we just attempting to minimize the amount of race-condition by testing?)

One of the reasons I like zsh is its copious expansion flags. If you aren't wedded to POSIX or bash syntax, consider zsh for this reason alone.

In the case of the first example he shows, the cat -n problem, you can do the following in zsh to expand the results of the wildcard globbing automatically:

    cat *(:A)
This will give cat full paths. Not significantly different from the PWD referenced with ./* in his example, but more universal in applicability, particularly when you start to use things like the file type filters:

    cat *(.:A)
giving you only files, not directories, and also expanding to absolute paths, while

    cat **/*(.:A)
does the same for plain files in the working directory and all subdirectories as well.

Remember to test your patterns with a print statement first:

    print -l **/*(.:A)
before passing them to a command.

Note also that some[1] commands will have a "--" (dash dash) flag indicating "end of flags", so (eg): "cat -- -n" really would cat a file called "-n"[2].

[1] on my BSD system, many internal Tcl commands honor this convention. Damned if I can find a section 1 shell command that uses the convention, but I'm sure I've seen them.

[2] my version of cat doesn't have a -- flag, so my example is contrived; not sure if GNU cat differs.

EDIT: typo, perl(1) supports "--". See perlrun(1) for details.

The original strength of Unix also ends up being such a commonly frustrating feature: Everything is marshalled through strings.

With human-manageable strings comes ambiguities, especially in concatenative situations like commandline expansion and SQL injection susceptible code.

There's really no good universal solution. Judiciously adding explicit boilerplate as the article describes, or using less open-ended syntax which ends up adding common syntactic overhead as well, are both more painful to the user in common cases.

Hmm ... I along with a couple of my friends spent the last two days at the DeveloperWeek hackathon trying to explore Watson's capabilites. IBM's PaaS solution is called BlueMix and all of Watson's capabilities are available as Services for you to use.

We tried using the "tradeoff Analytics" service for the project - and I must say , the tools and help available around it, the API and its documentation is pretty bad , convoluted and unusable. This is true too other services available through watson too.

We looked into IoT ( Internet of things ) as well . And once again , ran into a ton of dead ends without being able to proceed. The API documentation and examples just suck . If you are used to playing around with well documented APIs / Tools / Languages - this is going to be frustrating.

If the OP is the person who actually wrote the article , please please please go back to Watson Dev Cloud or BlueMix and try it out your services and APIs an a consumer.

That's an impressive result, considering how simple the algorithm really is. (The learning algorithm isn't obvious, but it's not a lot of code.)

Can this algorithm be run in reverse, to generate an image from the network? That's been done with one of the other deep neural net classifiers. "School bus" came out as a yellow blob with horizontal black lines.

An interesting question is whether there's a bias in the data set because humans composed the pictures, and humans like to take pictures of certain things. (Cats are probably over-represented.) Images taken by humans tend to have a primary subject, and that subject is usually roughly centered in the images. It might be useful to test against a data set taken from Google StreetView images, which lack such a composition bias.

Interesting, I've long wondered why parametric nonlinearities are not used more often. It adds very little to the overall parameter count (the number of units is most often dwarfed by the number of connections), but it should increase expressibility a lot (e.g. adaptively using soft or hard nonlinearities). Taken to its extreme, I've been toying with the idea of combining DNNs and Genetic Programming - using a large number of arbitrary symbolic expressions with high connectivity and many layers.

It seems that this might mean that ImageNet is becoming less useful a benchmark dataset. Some of the images have labels which I would have never guessed myself, and not because I don't know the difference between two types of stingray, but because I would have never said that the topic of the image was a seatbelt. It would be interesting to know how many errors are actually due to outputting a label which does exist in the image, but isn't in the labeled truth data and how many are plainly not in the image.
