...
The following information is out of date. It needs to be updated according to the latest Concepts Lite draft.
Section 3 of the constraints proposal covers this in reasonable depth.

Bomb dropping algorithm
...ave exactly the same minimum vertex cover for original vertices. Such transformation allows to align graph vertices to arbitrary positions on the grid.
If we place graph vertices only to even rows and columns (in such a way that no two edges incident to one vertex form an acute angle), insert "on...
User recognition without cookies or local storage
... or Com Object would have been an easy solution using a hash of hardware information, but these days people are so security-aware that it would be difficult to get people to install these kinds of programs on their system. This leaves you stuck with using Cookies and other, similar tools.

What are the calling conventions for UNIX & Linux system calls (and user-space functions) on i386 an
... is from the Linux-specific appendix to the ABI, and even for Linux it's informative not normative. (But it is in fact accurate.)
This 32-bit int $0x80 ABI is usable in 64-bit code (but highly not recommended). What happens if you use the 32-bit int 0x80 Linux ABI in 64-bit code? It still trunca...
What is a “cache-friendly” code?
... level I mean the largest == slowest. The cache hit rate is crucial for performance since every cache miss results in fetching data from RAM (or worse ...) which takes a lot of time (hundreds of cycles for RAM, tens of millions of cycles for HDD). In comparison, reading data from the (highest level)...
How can we match a^n b^n with Java regex?
...ktracking as you allow until the given pattern matches. This may impact performance (i.e. catastrophic backtracking) and/or correctness.

Some Terminology Differences to Sort Out

Monad in plain English? (For the OOP programmer with no FP background)
...a "bind" operation that takes a monadic value and a function that can transform the value, and returns a new monadic value. Bind is the key operation that defines the semantics of the monad. It lets us transform operations on the unamplified type into operations on the amplified type, that obeys the...
Controlling fps with requestAnimationFrame?
...ould be accepted. Here, forked your fiddle, to demonstrate using window.performance.now() instead of Date.now(). This goes nicely with the high-res timestamp that rAF already recieves, so there's no need to call Date.now() inside the callback: jsfiddle.net/chicagogrooves/nRpVD/2

When writing a directive in AngularJS, how do I decide if I need no new scope, a new child scope, or
... to "reach up" and grab values from the directive HTML seems like Very Bad Form.
I, too, wound up changing my app to have mostly child scope directives with very few isolates -- only those which don't need to access ANYTHING from the parent other than what they can be passed through simple, non-rep...
