adb not finding my device / phone (MacOS X)
...
Additonal Update : Do not underestimate the value of a good USB cable. Sometimes just swapping cables will help.
Update for newer versions of adb, ~/.android/adb_usb.ini has to be removed.

Check whether number is even or odd
...
You can use the modulus operator, but that can be slow. If it's an integer, you can do:
if ( (x & 1) == 0 ) { even... } else { odd... }
This is because the low bit will always be set on an odd number.

Why does this Java program terminate despite that apparently it shouldn't (and didn't)?
A sensitive operation in my lab today went completely wrong. An actuator on an electron microscope went over its boundary, and after a chain of events I lost $12 million of equipment. I've narrowed down over 40K lines in the faulty module to this:

How to “hibernate” a process in Linux by storing its memory to disk and restoring it later?
Is it possible to 'hibernate' a process in linux?
Just like 'hibernate' in laptop, I would to write all the memory used by a process to disk, free up the RAM. And then later on, I can 'resume the process', i.e, reading all the data from memory and put it back to RAM and I can continue with my proces...
Why should we typedef a struct so often in C?
...
As Greg Hewgill said, the typedef means you no longer have to write struct all over the place. That not only saves keystrokes, it also can make the code cleaner since it provides a smidgen more abstraction.
Stuff like
typedef struct {
int x, y;
} Point;
Point point_new(int x, int y)

Are getters and setters poor design? Contradictory advice seen [duplicate]
I'm currently working on a simple game in Java with several different modes. I've extended a main Game class to put the main logic within the other classes. Despite this, the main game class is still pretty hefty.

What is the Haskell response to Node.js?
I believe the Erlang community is not envious of Node.js as it does non-blocking I/O natively and has ways to scale deployments easily to more than one processor (something not even built-in in Node.js). More details at http://journal.dedasys.com/2010/04/29/erlang-vs-node-js and Node.js or Erlan...
Big-oh vs big-theta [duplicate]
It seems to me like when people talk about algorithm complexity informally, they talk about big-oh. But in formal situations, I often see big-theta with the occasional big-oh thrown in.
I know mathematically what the difference is between the two, but in English, in what situation would using big-oh...
Why Java needs Serializable interface?
We work heavily with serialization and having to specify Serializable tag on every object we use is kind of a burden. Especially when it's a 3rd-party class that we can't really change.

What are the differences between WCF and ASMX web services?
...
Keith Elder nicely compares ASMX to WCF here. Check it out.
Another comparison of ASMX and WCF can be found here - I don't 100% agree with all the points there, but it might give you an idea.
WCF is basically "ASMX on stereoi...
