Good or bad practice? Initializing objects in getter
...on of this issue is unnecessary as we will see shortly.
In general:
It's now time to look at lazy initialization in general:
Lazy initialization is usually used to delay the construction of objects that take a long time to be constructed or that take a lot of memory once fully constructed.
That is...
Shell one liner to prepend to a file
...table, and should not be relied upon for anything even vaguely important.
Now, with all that out of the way the answer was:
Creating another file descriptor for the file (exec 3<> yourfile) thence writing to that (>&3) seems to overcome the read/write on same file dilemma. Works for...
asynchronous vs non-blocking
...Window messages, whereas .NET asynchronous IO is free-threaded (you don't know what thread your callback will be called on).
So they don't always mean the same thing. To distil the socket example, we could say:
Blocking and synchronous mean the same thing: you call the API, it hangs up the thread...
Update a dataframe in pandas while iterating row by row

LINQ's Distinct() on a particular property
...
EDIT: This is now part of MoreLINQ.
What you need is a "distinct-by" effectively. I don't believe it's part of LINQ as it stands, although it's fairly easy to write:
public static IEnumerable<TSource> DistinctBy<TSource, TKey>...
How to determine if a number is a prime with regex?
...ce again the returning of the negation of the match result.
Do you see it now? It's unbelievably tricky (and computationally expensive!) but it's also kind of simple at the same time, once you get it. :-)
I can elaborate if you have further questions, like on how regex parsing actually works. But ...
