Long-held, incorrect programming assumptions [closed]
... that I was behind the curve on the things that all programmers must just know intuitively.
I've realized over time that I'm effectively comparing my knowledge to the collective knowledge of many people, not a single individual and that is a pretty high bar for anyone. Most programmers in the real...
Differences between ExpandoObject, DynamicObject and dynamic
...ave any use to you as the developer.
When you extend DynamicObject you are now able to provide CUSTOM behavior regarding how you want dynamic dispatch to resolve to data stored internally in your underlying data representation at run-time.
ExpandoObject stores underlying data in a Dictionary, etc. I...
Performant Entity Serialization: BSON vs MessagePack (vs JSON)
...
MessagePack now has a BINARY data type so the argument of 1-1 de-serialization compatibility to JSON is not entirely true anymore.

How does this print “hello world”?
...g the number with the mask 31₁₀ = 11111₂ in the sentence l & 31
Now the code maps the 5-bit value to its corresponding 7-bit ascii character. This is the tricky part, check the binary representations for the lowercase
alphabet letters in the following table:
ascii | ascii | ...
stringstream, string, and char* conversion confusion
...str();
}
IMO that's the best solution. Unfortunately it's not very well known.

Can I combine :nth-child() or :nth-of-type() with an arbitrary selector?
...ype(8), .rest:nth-of-type(9), .rest:nth-of-type(10){
display:none;
}
Now you must be wondering what is the difference between nth-child and nth-of-type so this is the difference

What is the difference between canonical name, simple name and class name in Java Class?
...n that would allow a malicious actor to work. Someone saying "oh, well we know classes will never start with lowercases/packages will never start with capitals". Granted, a malicious actor who has access to your class loader can already do terrible things, so it's probably not an absolutely terrible...
How can I pair socks from a pile efficiently?
...ce comparison is not required.
Case 3: The number of combinations is not known in advance (general case).
We have to do comparison to check whether two socks come in pair. Pick one of the O(n log n) comparison-based sorting algorithms.
However in real life when the number of socks is relatively s...
Why is std::map implemented as a red-black tree?
...implementation". Each implementer chooses an implementation. As far as we know, they've all chose RB trees, so presumably this is either for performance or for ease of implementation/maintenance. As I said, the breakpoint for performance might not imply that they think there are more inserts/deletes...
“Undefined reference to” template class constructor [duplicate]
...cases. The choice is yours.
The code in a template is merely a 'pattern' known to the compiler. The compiler won't compile the constructors cola<float>::cola(...) and cola<string>::cola(...) until it is forced to do so. And we must ensure that this compilation happens for the constructo...
