Quoting attributes is optional in HTML (though recommended).

If you're using the new G1 collector which ships in JDK 7, the only configuration parameters you really need to care about are the minimum and maximum heap sizes (-Xms and -Xmx) and perhaps the latency target (-XX:MaxGCPauseMillis).

So it's not all bad.

For anyone interested in how it will be implemented, see ko1's presentation slides from Euruko 2013.

Small steps. Just using some simple functional constructs like `map` and `filter` will do wonders for your code. You don't have to start writing everything in a purely functional manner to benefit from it.

What? Copenhagen alone has thousands of homeless people. And what makes you think that people choose to be homeless?

Be sure to read Moxie Marlinspike's comment (the first comment on the page) there.

What he means is true parallelism (although alternate ruby and python implementations have it).

The newer link doesn't mention them using Rails anymore. It's probably still in use in some internal apps, but the main twitter.com site should be 100% Scala now.

Does anyone have experience with using TypeScript with existing libraries like Angular.js?

I know that there are definition files for it [1] (and many other popular libraries), but unfortunately I haven't had the time to check out their quality.

Angular supports data-attributes as well.

If nothing else, it's easier to override with your own styles.

Very nice article. This is easily the biggest problem I have with CoffeeScript.

Google uses a different domain for user content, namely googleusercontent.com.

There is a simple todo app example on the angularjs homepage. It's one of the first examples there.

Good standards stem from real-world experience. It's best to implement something yourself (even better if there are other competing implementations), and then seek standardization.

It's an internal, automatically generated class. No programmer is ever going to use it.

The Live Edit functionality is provided by a plugin, so it should work in PyCharm as well. I know that it works in RubyMine.

Small correction: the iPad version isn't out yet, but apparently they're releasing it this summer.

ES6 is very important for them. For example, classes and modules in Typescript are essentially lifted directly from ES6, and they aim to remain compatible with ES6 as it evolves.

I can share much of the thoughts regarding RubyMine (a Ruby IDE by JetBrains). While it is not the best text editor out there (I used to use Emacs for Ruby stuff), the IDE features are great and (for me) outweight some of the niceties that Emacs or Your Favourite Text Editor has. Symbol navigation works across libraries and the graphical debugger is great. Autocompletion could be better, but I understand how the dynamic nature of Ruby (and especially Rails, which uses a lot of metaprogramming magic to do its thing) makes it sometimes hard to do 100% accurately.

(I'm not affiliated with JetBrains, just a happy customer)

The EULA forbids you to run OS X on non-Apple hardware though.

"to install, use and run up to two (2) additional copies or instances of the Apple Software within virtual operating system environments on each Mac Computer you own or control that is already running the Apple Software, for purposes of: (a) software development; (b) testing during software development; (c) using OS X Server; or (d) personal, non-commercial use."

It can be more convenient, but the added type safety prevents the programmer from doing many kinds of common mistakes. It's a trade-off.

It's also 2 years old, so a lot might've changed.

Fair enough.

Facebook has rules forbidding hate speech. Is that not hate speech to you?

Either Last-Modified or Etag is sufficient. Most servers will add both, though.

Edit: The difference is that Last-Modified allows clients to use a heuristic to determine if the response should be cached for a certain duration (unless explicit Cache-Control or Expires headers are used). The heuristic isn't specified, but a 10% fraction of Date - Last-Modified is suggested, and in fact, that is what e.g. Internet Explorer does.

One such tool is Swagger [1]. The nice thing about it is that it can automatically write you a client as well. There are client implementations for many programming languages, such as Java, Scala, Clojure, Ruby, Python, PHP, Javascript and C#.

I like the idea, but the layout is pretty broken in non-Webkit browsers.

For Play, you'll want to either 1) handle the (blocking) database queries using Futures/Actors that use a separate thread pool (this might be easier to do in Scala) or 2) bump the default thread pool sizes considerably. The default configuration is optimized purely for non-blocking I/O.

See e.g. https://github.com/playframework/Play20/blob/master/document... and https://gist.github.com/guillaumebort/2973705 for more info.
