What is the formal difference in Scala between braces and parentheses, and when should they be used?
...er, there’s more you need to know to better grasp these rules.
Increased compile checking with parens
The authors of Spray recommend round parens because they give increased compile checking. This is especially important for DSLs like Spray. By using parens you are telling the compiler that it s...
Using ThreadPool.QueueUserWorkItem in ASP.NET in a high traffic scenario
...y overloaded? If you're running into this situation, you need to redesign completely!
Most of the time I see or hear about multi-threaded code being inappropriately used in ASP.NET, it's not for queuing CPU-intensive work. It's for queuing I/O-bound work. And if you want to do I/O work, then you...
How do Trigonometric functions work?
....
Once you've reduced your argument, most chips use a CORDIC algorithm to compute the sines and cosines. You may hear people say that computers use Taylor series. That sounds reasonable, but it's not true. The CORDIC algorithms are much better suited to efficient hardware implementation. (Softwa...
Why are const parameters not allowed in C#?
...seful form of "const" annotation in C#, an annotation that both humans and compilers could use to help them understand the code, and that the runtime could use to do things like automatic paralellization and other advanced optimizations.
For example, imagine if you could "draw a box" around a hunk...
Traits vs. interfaces
... must implement.
When a trait is use'd the implementations of the methods come along too--which doesn't happen in an Interface.
That is the biggest difference.
From the Horizontal Reuse for PHP RFC:
Traits is a mechanism for code reuse in single inheritance languages such as PHP. A Trait is i...
List of ANSI color escape sequences
...;5;57m #That is, \033[48;5;<BG COLOR>m
And, of course, you can combine these:
\033[38;5;206;48;5;57m
The 8-bit colours are arranged like so:
0x00-0x07: standard colors (same as the 4-bit colours)
0x08-0x0F: high intensity colors
0x10-0xE7: 6 × 6 × 6 cube (216 colors): 16 + 36 × r ...

live output from subprocess command
I'm using a python script as a driver for a hydrodynamics code. When it comes time to run the simulation, I use subprocess.Popen to run the code, collect the output from stdout and stderr into a subprocess.PIPE --- then I can print (and save to a log-file) the output information, and check for ...
