Accessing private member variables from prototype-defined functions
...methods.
The drawback is that this is the only thing that's different each time a prototypal function is called.
Therefore, any private fields must be accessible through this, which means they're going to be public. So we just stick to naming conventions for _private fields.
Don't bother mixing Cl...
How to capture stdout output from a Python function call?
...sys.stderr = self._stderr
Example usage:
from Capturing import *
import time
capturing = Capturing()
def on_read(line):
# do something with the line
capturing.print("got line: "+line)
capturing.on_readline(on_read)
capturing.start()
print("hello 1")
time.sleep(1)
print("hello 2")

Large Object Heap Fragmentation
...s behave very differently in allocation as well. The main heap is (at this time) basically a stack in allocation patterns - it always allocates at the top, ignoring any free space - when compaction comes, the free spaces are squeezed out. This makes allocation almost a no-op, and helps data locality...
API Keys vs HTTP Authentication vs OAuth in a RESTful API
...n, once John has authorized the delegation; ServiceX will be then issued a time-based Token to access the Google Account details, very likely in read access only.
The concept of API Key is very similar to OAuth Token described above. The major difference consists in the absence of delegation: the U...

Use CSS3 transitions with gradient backgrounds
...I tested gradient transitions in 2016 in IE and they seemed to work at the time, but my test code no longer works.)

Gradient transitions with un-prefixed new syntax [e.g. radial-gradient(...)]now confirmed to work (again?) on Microsoft Edge 17.17134. I don't know when this was ...

Unit testing code with a file system dependency
...ils to the test. This is bad because now you have to change the test every time you change the implementation details of your method because changing the implementation details breaks your test(s)!
Having bad tests is actually worse than having no tests at all.
In your example:

Why isn't sizeof for a struct equal to the sum of sizeof of each member?
...tly in the struct at fixed offsets. The compiler knows all this at compile time so the pointer is implicit. For example, if you have a struct variable of this type called s then &s.a == &s and &s.d == &s + 12 (given the alignment shown in the answer). The pointer is only stored if t...
Calling a JavaScript function named in a variable [duplicate]
...Space["functionName"]();
Avoid eval, and avoid passing a string in to setTimeout and setInterval. I write a lot of JS, and I NEVER need eval. "Needing" eval comes from not knowing the language deeply enough. You need to learn about scoping, context, and syntax. If you're ever stuck with an eval, j...
