I had to open things in a new tab (in chrome) to see them (odd, but it worked?) Edit: Seems to be working now anyways :).

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 h…

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…

nice! similarly, var oldPlaceObject = map.placeObject; var newPlaceObject = function(x, y, type) { if (type !== 'block') { map.placeObject = oldPlaceObject; map.placeObject(x, y, t…

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…

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 remov…

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 n…

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…

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/whi…

The College Board is releasing previously-unreleased SAT questions on Khan Academy, with answers and explanations [1]. The College Board announcement emphasized the importance of p…

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 …

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 …

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 …

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, i…

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 anyt…

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". Phrasin…

When I first turned over my copy of the issue, I was holding the magazine by the corner exactly as one would hold a portrait iPad mini. In addition to showing the actual size, I 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 fl…

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 us…

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…

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!
