Browser doesn't scale below 400px?
...to the right instead of to the bottom
Resize the inspector panel - you can now make the browser area really small (down to 0px)
Update: Chrome now allows you to arrange the inspector windows vertically when docked to the right! This really improves the layout.
The HTML and CSS panels fit really...
Which characters are valid/invalid in a JSON key name?
...d key. It can even have " as long as you escape it:
{"The \"meaning\" of life":42}
There is perhaps a chance you'll encounter difficulties loading such values into some languages, which try to associate keys with object field names. I don't know of any such cases, however.

Is it good practice to NULL a pointer after deleting it?
... Imagaine a mainainer comming back a year later and seeing foo deleted. He now believes he can re-use the pointer unfortunately he may miss the second delete (it may not even be in the same function) and now the re-use of the pointer now gets trashed by the second delete. Any access after the second...
Hidden features of Eclipse [closed]
...y = new |
and then I pushed Ctrl-Space to complete the constructor call. Now I type:
new Display()|
and press Ctrl-2 L, which results in:
Display display = new Display()|
This really speeds things up. (Ctrl-2 F does the same, but assigns to a new field rather than a new variable.)

Upgrading Node.js to latest version
So, I have Node.js installed and now when I tried to install Mongoosejs I got an error telling me that I don't have the needed version of Node.js (I have v0.4.11 and v0.4.12 is needed).

explicit casting from super class to subclass
... you're essentially telling the compiler "trust me. I'm a professional, I know what I'm doing and I know that although you can't guarantee it, I'm telling you that this animal variable is definitely going to be a dog."
Since the animal isn't actually a dog (it's an animal, you could do Animal anima...
What is the difference between include and extend in Ruby?
...class (i.e. the singleton class)
e.g.
if you call Klazz.extend(Mod), now Klazz has Mod's methods (as class methods)
if you call obj.extend(Mod), now obj has Mod's methods (as instance methods), but no other instance of of obj.class has those methods added.
extend is a public method
include -...
Java Programming - Where should SQL statements be stored? [closed]
...tch from DB server without the need to change your model (but ask yourself now: how often would a company switch from DB server? likely at least only once per 3 years, isn't it?).
I won't call stored procedures a "good" solution for this. They have an entirely different purpose. Even though, your c...
Returning an array using C
...allocating ret)
char *foo(int count) {
char *ret = malloc(count);
if(!ret)
return NULL;
for(int i = 0; i < count; ++i)
ret[i] = i;
return ret;
}
Call it like so:
int main() {
char *p = foo(10);
if(p) {
// do stuff with p
free(p);

Is std::vector so much slower than plain arrays?
...d::vector<Pixel> pixels(dimensions * dimensions, Pixel(255,0,0));
Now doing the same timing again:
g++ -O3 Time.cpp -I <MyBoost>
./a.out
UseVector completed in 2.216 seconds
The vector now performance only slightly worse than the array. IMO this difference is insignificant...
