...fference, they are the same thing.
2020-08-20 Update: While GUIDs (as used by Microsoft) and UUIDs (as defined by RFC4122) look similar and serve similar purposes, there are subtle-but-occasionally-important differences. Specifically, some Microsoft GUID docs allow GUIDs to contain any hex digit in...
Differences between utf8 and latin1
...s article useful (and even more if you know a bit Java).
Note that full 4-byte UTF-8 support was only introduced in MySQL 5.5. Before that version, it only goes up to 3 bytes per character, not 4 bytes per character. So, it supported only the BMP plane and not e.g. the Emoji plane. If you want full...
Python: Using .format() on a Unicode-escaped string
...coding for your environment, which was likely set to UTF-8. (You can check by doing import sys; print sys.stdout.encoding)

Perforce for Git users? [closed]
...rce people can live in harmony working on the same code, mostly unaffected by their co-workers choice of version control. Git Fusions 13.3 is available from the Perforce web site. It does need to be installed by the Perforce administrator, but if you install it you will find that its repository slic...
Default constructor vs. inline field initialization
...you can save lines of code (and make your code slightly more maintainable) by keeping initialisation in one place.
Like Michael said, there's a matter of taste involved as well - you might like to keep code in one place. Although if you have many constructors your code isn't in one place in any cas...
Pointers in Python?
...-- and the top-voted A is telling you "don't do it, get over it", followed by one that goes "it's just how it is". While you may not "appreciate" Python-knowledgeable people reacting with astonishment to your original specs, they are quite astonishing in themselves;-).

How do I parallelize a simple Python loop?
... to execute {sum(output2)} = sum({repr(output2)})')
print(f'time saved by parallelizing: {sum(output2) - (finish-start)}')

main()
And here's the output:
$ python3 -m futuretest
