How do I speed up the gwt compiler?
...ditional overhead from compile time.
Bottom line: you're not going to get order-of-magnitude increase in compiler performance, but taking several relaxations, you can shave off a few minutes here and there.

What is an SSTable?
...
"An SSTable provides a persistent,ordered immutable map from keys to values, where both keys and values are arbitrary byte strings. Operations are provided to look up the value associated with a specified key, and to iterate over all key/value pairs in a spec...
What does Provider in JAX-RS mean?
...f them as plugins that (potentially) alter the behavior of the runtime, in order to accomplish a set of (program defined) goals.
Providers are not the same as resources classes, they exist, conceptually, at a level in-between resources classes and the JAX-RS implementation. If it helps, you can thi...
How do you use “
...ountered." In other words, it will keep going through the environments in order until it finds a variable with that name, and it will assign it to that. This can be within the scope of a function, or in the global environment.
In order to understand what these functions do, you need to also under...
Understanding how recursive functions work
...ot been able to grok yet. Filtering out all of the (extremely clever) "In order to understand recursion, you must first understand recursion." replies from various online threads I still am not quite getting it.

Android Fragments and animation
...mFragment );
transaction.addToBackStack(null);
transaction.commit();
The order is important. This means you must call setCustomAnimations() before replace() or the animation will not take effect!
Next these files have to be placed inside the res/anim folder.

A semantics for Bash scripts?
...ion to Bash as a programming language. For example: What is the evaluation order? what are the scoping rules? What is the typing discipline, e.g. is everything a string? What is the state of the program -- is it a key-value assignment of strings to variable names; is there more than that, e.g. the s...
Convert objective-c typedef to its string equivalent
... array.
Make sure the indexes are the appropriate enums, and in the right order (otherwise exception).
note: names is a property synthesized as *_names*;
code was not checked for compilation, but I used the same technique in my app.

What is the difference between cout, cerr, clog of iostream header in c++? When to use which one?
...e writing an error through cerr, which keeps the messages in chronological order of their generation when both are directed to the same terminal/file/etc..
This contrasts with clog - if you write there it won't be buffered and isn't tied to anything, so it will buffer decent sized amounts of loggin...
Haskell, Lisp, and verbosity [closed]
...answer:
almost anything you can do with macros you can do with a higher-order function (and I include monads, arrows, etc.), but it might require more thinking (but only the first time, and it's fun and you'll be a better programmer for it), and
the static system is sufficiently general that it n...
