For anyone else running into the same problem, I just copied my HipChat.app in /Applications, and ran the second hipchat next to the first hipchat (you can also change the second hipchat's icon for easy distinguishment). It's

I've found using hipchat with coworkers to be much nicer than using XMPP with coworkers mostly for it being closer to IRC: there are rooms where most discussion takes place, so you can get to know people by lurking there, and when you

nice! similarly, var oldPlaceObject = map.placeObject; var newPlaceObject = function(x, y, type) { if (type !== 'block') { map.placeObject = oldPlaceObject; map.placeObject(x, y, type);

First, I'm very sorry about that! Second, wow, a scale factor of 256! Off the top of my head it might be numerical error building up. If that's the case, I'm very sorry. (It's also sometimes possible to get infinitesimal

Thanks for the feedback! The undo button thing would be a huge improvement; I'll fix that. (Also, if you do two transformations that cancel each other out, it will notice and remove both rather than adding two. So you can actually undo

Maybe more importantly, they would know whether their message was classified as spam (or a pretty good heuristic thereof). A naive bayes classifier for spam relies on the spammer not knowing whether the message was marked as spam or not. Su

Like most tests, my personal opinion is that it tests both how well you know the material as well as how familiar you are with the format and content of the test. There is value in the former, and hopefully more access to preparation materi

Thanks! Yes, I agree that full-length tests are important. We're not there yet, but I think we'll improve on that with time (there has been some talk of different styles of how/which/how many questions appear in an exerc

I don't have any practical experience with angular (but I'd like to, and definitely think its testability is a step in the right direction). That said, I've found react to be very declarative, especially over the raw jQuery a

I learned them concurrently, translating lua in Programming in Lua into the equivalent moonscript. It's a pretty strait-forward translation and is definitely doable. I already had experience with a reasonable variety of languages before lea

I've used moonscript a lot, and don't particularly like the \ syntax. However, you get used to it quickly, and it stops seeming like such a big deal. It would be hard to have both be '.', because of lua semantics: '.' means "get the propert

Sure, but isn't it awesome if, instead of being just one unit tests, you can have some critical checks running in every unit test (and when running the code as a whole)? However, if you're going this route, it might be worth having a second

While I agree with the overall sentiment of the article, the hypothetical monetization numbers in the last paragraph are just ridiculous. Getting 20% of a free userbase to pay anything is extremely high. ~0.2% to 2% sounds like a more likel

I had a friend in college who used to use this, as well as "...is left as an exercise to the reader" on homework assignments, to my great amusement.

I've been trying to use something closer to ColinDabritz's second wording: "What am I missing that makes ____ unreasonable?" or "I don't understand why ____ wouldn't work". Phrasing it like this hopefully conveys both that I'm aware that th

If you stick to integer math with 64-bit floating point numbers, then everything actually works out pretty reasonably, since all 32-bit ints can be represented exactly as 64-bit floats (doubles). As long as you use floor/ceil/round where ap

Yep, there's nothing preventing it, although I don't know enough about systems like Corona, Codea, or Moai to know whether you'd miss out on any IDE functionality. I'm currently using moonscript to power my side project on iOS. It's great!

The lua ecosystem is extremely simple to embed in a native application, which, as someone who has had to do it, is something that feels underappreciated. Python and javascript were harder to set up for embedding on the same computer, and al

Cool! I was aware that variable reassignment didn't carry over in for loops, but I didn't know that the variables in each iteration were independent. Keep up the good work!

It's great to see more development of the language! MoonScript is great if you're looking for the niceness of CoffeeScript in an embedded environment (Lua's semantics also behave more sanely than Javascript's). I have roughly 5000 lines of

I could go on about my opinion on this for a while, but to keep it short [edit, ok, maybe I failed at "short"]: - If you like programming/CS, then studying CS in college can be fun (once you figure out if you're more into programming or the

+1 love, love, love the simplicity of the Lua language. If I were teaching introductory programming it would be high on my list of languages to consider. (I wish its syntax was a little less verbose, but that's why I use http://moonscript.
