What are the mathematical/computational principles behind this game?
...m (this is the same).
Every two lines meet in exactly one point (this is a bit different from Euclid).
Now, add "finite" into the soup and you have the question:
Can we have a geometry with just 2 points? With 3 points? With 4? With 7?
There are still open questions regarding this problem but we...
What is the strict aliasing rule?
... int b;
} Msg;
void SendWord(uint32_t);
int main(void)
{
// Get a 32-bit buffer from the system
uint32_t* buff = malloc(sizeof(Msg));
// Alias that buffer through message
Msg* msg = (Msg*)(buff);
// Send a bunch of messages
for (int i = 0; i < 10; ++i)

Eclipse, regular expression search and replace
... to solve and we wouldn't know how to use RegEx in there. So I am adding a bit of explanation to this. The answer is
search: (\w+\.someMethod\(\))
replace: ((TypeName)$1)
Here:
In search:
First and last '(' ')' depicts a group in regex
'\w' depicts words (alphanumeric+underscore)
'+' depicts on...
Linking static libraries to other static libraries
... extracts the corresponding object files from lib2 with ar, renames them a bit, and puts them into lib1. Now there may be more missing symbols, because the stuff you included from lib2 needs other stuff from lib2, which we haven't included yet, so the loop needs to run again. If after some passes of...
Context switches much slower in new linux kernels
...l power hog. It will disable C1/C1E, which will remove the final remaining bit of latency at the expense of a lot more power consumption, so use that one only when it's really necessary. For most this will be overkill, since the C1* latency is not all that large. Using my test application running on...
Default value in Go's method
.... For example:
func SaySomething(say string) {
// All the complicated bits involved in saying something
}
func SayHello() {
SaySomething("Hello")
}
With very little effort, I made a function that does a common thing and reused the generic function. You can see this in many libraries, fmt...
Eclipse: have the same file open in two editors?
...that seem to have cleared up in Neon.
Mars Note: The split editor seems a bit buggy. The JavaScript editor likes to jump the cursor to the other pane momentarily when it does a while-you-type-validation.

Understanding implicit in Scala
....
Luigi's answer is complete and correct. This one is only to extend it a bit with an example of how you can gloriously overuse implicits, as it happens quite often in Scala projects. Actually so often, you can probably even find it in one of the "Best Practice" guides.
