I think you should focus on changes that will provide bigger gains. From joncalhoun comment I heavily endorse the retargeting sugestion, but I don't think you should worry so much about AB test for now. AB test depends on some heavy and constant traffic and a more predictable knowledge of your audience behavior. I think you are too early on it to gain a lot from AB testing.

Another sugestion is assortment and marketing. I think you already have very good channels and niche, but you might exepriment a little more.

Please, read all this presentation: http://www.heavybit.com/library/video/2013-07-16-michael-dea...

For example, i would suggest you try the market for your product for imternational students. Exchange might need the exact same product, but you will have to validate it and validate the channels for it. This is an example of assortment, but you should really see the video above and develop your own ideas about to find new markets and scale a little more.

And from what I could see you are doing great. Very well done validation, distribution and website. I predict a lot of success for you.
FWIW, the smalltalk browser _look_ ("hierarchical" selector blocks on top and content at the bottom) has been an available UI in java in eclipse for years, and IMO it's far better than the tree-ish browser on the side exactly because it helps with getting more context on screen
I wonder if the statement about Newton's second law (there exists an r(-t)) holds true when you include relativistic effects.
Just curious, which Chromebook do you use and have you experimented with the maximum sample rate it can handle?
I wonder how feasible it would be to rotate a ringworld at a speed not to replicate gravity, but to negate the sun's gravity. So at 1AU it would orbit in roughly the same length of time as Earth itself.
Yello.

The table doesn't look that bad - for the first page, if sorted by "requiring law degree" column, for all schools at least 70% work either at job that requires or prefers law degree. Of course, if you look at the worst ones, the figures are abysmal, but isn't that somewhat expected?

I'd like to see another table however - which correlates the law-related employment chance with the cost of the law degree. E.g., how much chance of being a lawyer you can buy for $10k?
You are so right! (I blame the macro expansion based semantics of TeX packages.)

I end up using a small number of very large packages that do almost everything I need instead of trying to get numerous more focused packages to work together. (Memoir or KOMA, and TikZ handle most of my tasks.)

I see. I'm not aware of any case law either.

I don't think it's good practise, and agree that it's hysterical, and think it stems from unthinkingly believing Microsoft's anti-OSS claims during their decade-long freakout about open source and the GPL.

I think that attempting to convince people not to participate in sharing and studying code with the rest of the world is an evil thing that they did, especially since the GPL was the most popular OSS license at the time.
> Clojure is functional because of it's use of concepts like "functions are first order objects", closure, higher order functions, etc. I would never consider Clojure imperative.

I would agree with that. Putting Clojure in the imperative camp seems a little skewed.

From the front page of clojure.org "Clojure is predominantly a functional programming language, and features a rich set of immutable, persistent data structures."

But I don't think that's his point as seancorfield pointed out.
An outsider's perspective:

Burning Man : Silicon Valley :: Gathering of the Juggalos : Rest of America.
Root SSH/Telnet/ADB,
Access/Modify DNS Servers,
Google OTA's Disabled,
Custom Boot Image,
Custom OTA Update Engine (Read more Here:http://ota.team-eureka.com/),
FlashCast Recovery Image
That's close to what I meant.

Closer would be:

Clojure def is imperative because the semantics are defined mechanically, leaving fewer implementation details up to the implementer. http://clojure.org/special_forms#Special Forms--(def symbol init?)

Haskell toplevel function definitions are more declarative because the semantics are defined less concretely. https://www.haskell.org/ghc/docs/latest/html/users_guide/inf...

This is what I meant. I did not mean to start a flame war about the definition of declarative. It's more about different approaches to language design.

Well, you can't ruin something that's already ruined - that is to say, Burning Man hasn't been Burning Man for a long time. I don't mean that in a cynical or superior way, just in a realistic one - it's become a very different thing from what it was even ten years ago, let alone twenty. What was once anti-establishment has become established, and an iconoclastic anti-brand has become the most powerful brand of its kind. It's a triumph in a way; it means it struck a chord and, as Josh says, it's a net positive. But the changes have rewrought Burning Man into a Burning Man theme park. The lunatics have surrendered the asylum. It's okay to mourn that, but it's a bit late to be pointing fingers. If you don't like it, start something new. That's how things like Burning Man happen in the first place.

Is the joke based on the idea that Juggalos are the dregs of society, and the dregs of Silicon Valley go to Burning Man?

Or do you mean it's a camping and music event for Silicon Valley?

I agree wholeheartedly with your last sentence - stopping transmission in West Africa and improving health systems is key.

I don't agree with your other points though. Ebola patients are only infectious while symptomatic, so accidentally bumping into someone on the subway is not the kind of direct contact needed for transmission. And although the virus can be present in sweat, it's mostly blood, fecal matter, etc. that transmit.

If there were a case introduced in the United States, it's not entirely out of the question that there would be a secondary case or two. Not probable, but not impossible, either. However, I truly believe there would be no more than one secondary generation (two at the absolute max). Western countries can mobilize effective isolation, quarantine, and contact tracing in ways that overburdened West African countries cannot.
I can't help but wonder if we'll see USB condoms that help to protect against spying through EM/power draw changes, i.e. to spy on decryption activities.

This is the only real solution (even if it's through an intermediate agent, which may have the same problem. Remember Google Reader). Of course, then the problem to keep that info in a good way (indexable, accessible, backed up, etc...) is another interesting problem. I'm afraid that most of the people are simply not aware of all of this (both on the content supplier or the content consumer)

This is also somehow of a problem on printed books. There are tons of books that are out of print and cannot be easily found.

I can attest, through the experience of living here (and occasionally cycling here) that Wales is in fact "hillier" than England at least! But I think Scotland beats Wales on hills.

So, personal experience; just slightly more scientific. But only slightly.
"Look at all the cool things we build and bring to Burning Man - no way we're ruining it!" is pretty much the exact same argument as "gentrification has resulted in far better brunch options in this area, no way we're ruining it!"

That being said, I thought this piece was super awesome for the insight into why tech folks go: it's a great way to show off and build something cool. Probably, folks are motivated by the same reasons my engineer friends back in Saskatchewan build progressively wackier campers to take to Craven Country Jamboree: a little to flex their hacker muscles, a little to blow off steam, a little to fly their freak flags and see who clicks with them. And that's nice. But it's worth noticing that so many pieces of Burner lore are now dependent on being subsidized by really rich folks. If we're being honest about how the economy of Burning Man works, it's becoming less an example of extreme self-reliance and more an example of of extreme patronage on behalf of the really rich.

And in itself, patronage isn't bad at all. It's great! But why doesn't this attitude extend to life back in the city? Why is Burning Man the one place that a rich person can help other folks out? Why is Mark Benioff the one dude who seems to give substantial amounts of money to people in the place he lives?

There are many comments discussing whether length should be unsigned or signed. There are arguments for and against it. This a prototypical carpet bump, you squash it in one place it raises its head somewhere else.

I see it not as a question whether lengths should be signed or unsigned but whether subtraction, assignment etc should be polymorphic w.r.t signed and unsigned. I think the issue here is the polymorphic variants of these binary operators are inherently risky.

Casting gets a little tedious, but languages that do not have operator overloading should disallow subtraction from unsigned and subtraction that return unsigned. You either cast it up, or if possible reorder the expression/comparison so that the problem goes away. Even assignment can be a problem. Ocaml can get irritating because it takes this view but I think it is safer this way.
It is very hard to be always vigilant about the unsigned signed issue, but hopefully a compiler error will mitigate risks, not completely, but it is better than nothing.

That leaves languages that allow operator overloading, in those cases if you are overloading an operator you better know what you are doing, and watch out for cases where the operator is not closed.

So I have the 2gb c720. I just shut most everything down except for a couple of terminal windows that didn't look like they had anything going on. I am on Gnome Shell on 14.04, and with the compositing perhaps this makes this crappier. I also had the device in the USB 3 port.

I was able to get 6 megs a sec with GQRX. 7 had occasional but reasonable stuttering. It is possible that without the compositing this would be better, and also I would think a GRC graph without any UI updating (or even without X) may perform even better.
Let's put it in English: Burning Man is to Silicon Valley as a gathering of Juggalos is to the rest of America. He probably means there aren't a whole lot of influences that can be detected in either direction in either of those relationships, he's surprised at the line: "In the end, Burning Man has likely influenced the tech industry’s culture much more than the other way around."
Yeah.

I've never even been to Burning Man, but this is a completely predictable result for anything that reaches any level of popularity.

No system made up of people can scale and maintain its original identity, whether it is a IRL event like Burning Man or a website like reddit or Hacker News. People who were there before some new group will always define an easily identifiable scapegoat group of those who are ruining the thing, but really it is just a numbers game. The more people you add, the less easily identifiable shared culture there can be, the more regulations have to be put into place and the more that community loses what the original members saw as its identity.

I believe this is an immutable, unsolvable problem short of (as devindotcom suggests) breaking off and starting a new new thing that replaces the old new thing (and obviously this is only a temporary solution that will have to be iterated again if the new new thing becomes popular).
Time is reversible in general relativity, in the sense that if you replace t by -t everywhere the solution is still valid. I don't remember the full proof off the top of my head, and the argument I do remember is complicated.
To add to that. I'm sure Space X attempts to collect all the debris that falls to the ground.
If you subscribe to the idea of a division of labor between systems and scripting languages, then Python + its C based extensions (Cython, Numpy, etc.) is ideal, as it already has an extensive scientific ecosystem. Julia combines the two in a single language. See this blog post and the one that follows it: http://graydon2.dreamwidth.org/3186.html
Cheers for your comment, I'll take a look at the presentation now and get back to you - looks interesting.

Many people just don't have the clue to make usable local archives.

You're also proposing mass copyright infringement which - stupidly in this example - is not legal.
Note that Emacs' window splitting ability doesn't stop at splitting the editor in two. You can recursively keep splitting as much as you want: when navigating complex code bases it has helped me in the past to have it split into four sections. More splits than that made the displayed sections too small for my taste, and even if you have all those splits right in front of you I personally felt that I had a harder time keeping track of where to look.
Is saving a webpage to your local harddrive copyright infringement? The data is already on your local system when you view a webpage.
thanks to all. I'm studying AI, so maybe there will be something good for Julia BUT we are reaching only now good libraries for Python.
They are porting good R libraries, there is Theano, pandas, scikit-learn, pylearn2 etc. With Julia? Let's see but it's a shame we start again :(((
You subtract lengths from other lengths all the time. How far have you gone recently? How much taller are you than your wife? Subtracting a length from another length isn't a problem at all; a problem would be if you wanted to subtract a length from a weight.

This

> Naturals are not closed under subtraction or negation, and therefore you should never negate or subtract a length.

assumes that a paramount goal in having types is to make function signatures like the following impossible:

public static String format(String format, Object... args);

Infinite-dimensional vectors (in which the first element is a String) sure aren't closed under format -- it maps them to scalars! But somehow string formatting is wildly popular. Or think of

public Color(int r, int g, int b);
public Color(int rgb);

Are you comfortable having a mapping from ℤ to Color, and from ℤ^3 to Color? If so, why does it bother you less than a mapping from ℤ ∩ [0, ∞) to ℤ ∩ [-1, ∞)?

Try a simple rewording of your argument: Hash tables aren't closed under access. Therefore, you should never retrieve values from a hash table.
It spreads via saliva and survives on surfaces, and the "symptomatic" period starts like a fever. It's not as if people go from being healthy to bleeding from every orifice in 24 hours. It's a hard disease to stop because it initially looks like a thousand other common illnesses.

Again, we're telling ourselves comforting bedtime stories when we pretend that there's something innate to the virus that makes us safe. We've just never had an outbreak in a city before, so we've had the advantage of geographical isolation.

Take a few incipient cases and stick them in a tenement in New York or Paris, and the epidemiology can become incredibly complicated before we even know we have a problem.
The advantage here is that you can take a common JS codebase, abstract the platform APIs that you use out, and run it on the web and iOS. The platform layer developers will probably need to understand Cocoa and iOS well, but the other application developers might not need to so much.

It's nice to see a Chinese chef marrying traditional cooking with elements of international haute cuisine. Hopefully this will become a trend, and Ms Dunlop is the perfect person to observe it.

- I managed to find some low-res photos of his dishes on this review site: http://www.dianping.com/shop/5423060

The 3 reviews are actually all positive despite one of them giving low ratings. They praise the place's traditional & intimate ambiance, intricate presentation and plating, and of course the taste of the food. Price per person is about RMB450, or US$73 - very high for China, as the article notes.

- I couldn't find evidence via Google that Japanese people are discussing the restaurant online, but maybe it's spreading via non-public word of mouth.

- After sharing this article on Facebook, I have friends interested in visiting Chengdu. Let's see if this becomes a small phenomenon among the international gastronomic crowd.
It is interesting. I held off on learning Python because Matlab was there (paid by school/employer), it ran reasonably fast, and all the libraries (toolboxes) were there.

Now I'm trying to jump to Julia and many of my Python friends are making the exact same arguments (you'll never get the community/libraries/support) that used to made against Python in favor of Matlab.

Anyway, as a long time Matlab user, Julia just feels incredibly 'natural' to me.

Checklist of Rationality Habits
People have different needs, and I get reminded of this when talking about editors/IDEs with others. Had a friendly 'discussion' with a dev a couple years back who was leading a discussion group and publicly scoffed when I mentioned I'd picked up IntelliJ. He went on to talk about his company's code and how 'lean' it was and how they didn't need any 'heavyweight' tools like a Java IDE.

I asked him about the code he was working on. How much of it did he write? "A lot". How much was written by people at the company "100% in house - we write everything from scratch". OK, great. Working on the exact same codebase with the same core team for years on end (2+ years in their case), you probably know every single bit and byte by heart - awesome. Very few of us operate in that world. Many of us come in to codebases where we didn't write every line. The original gone, hostile or possibly even dead at this point. Full-featured IDEs (the guy in question kept gushing over sublime-text and how fast and lean it was) provide another level of code insight that basic editors don't provide (not ragging on ST, just pointing out it doesn't do what I need for the breadth of projects I work on).

I think the OP needs to look deeper at the tools he's criticizing before writing them off. His ctrl-f example demonstrates that he doesn't seem aware of other IDEs that provide this (and... I'd probably use ctrl-f to find something, not fork).

In the vEdit example, we get 'what file do you want to open?' That's generally precisely what I don't want to think about when I come in to a new project, because I want a visual overview of what's available. I want to see the naming convention, the layouts, note what's available and what's not. Removing that in an effort to be 'simple' hinders a heck of a lot of automatic project discovery for the sake of ... what? 'Simplicity'?
Was his server hacked due to the recent vulnerability found in ElasticSearch?
Julia's a nice language even without the speed improvements. It's less overtly object oriented than Python, which could be a pro or con for you. I like its multiple dispatch, for example.

But it is pretty fast too :)
Since 2008 or so I've been saving all pages that I would otherwise be bookmarking. Only in MHT format, but it's convenient. After reading a few quotes on linkrot years ago, and noticing many pages I'd come back to 404'ing I decided bookmarks are useless long term (or even at times short term).
Does anybody know anything more than I about what this will enable (now)? Or is this just the first step of many in creating a hacker community around the Chromecast and software is to come? I've got one, and I'd love to make better use of it, or even help develop some stuff for it if it's that time :)
Well, I use an Android phone, but regardless, I've never given anyone permission. Maybe in a legal sense someone could claim that, but that's irrelevant to what's actually happened.

Interestingly, my Conception project shared a similar history. It started off as small individual boxes on a large canvas, but the latest version is currently more like Sublime.

I still haven't committed to either one paradigm, there are just certain problems with an open large canvas model that need to be resolved for it to be usable for large tasks.
