Why should we NOT use sys.setdefaultencoding(“utf-8”) in a py script?
...om the default ASCII to other encodings such as UTF-8, which the Python runtime will use whenever it has to decode a string buffer to unicode.
This function is only available at Python start-up time, when Python scans the environment. It has to be called in a system-wide module, sitecustomize.py,...
Get last n lines of a file, similar to tail

Visual Studio popup: “the operation could not be completed”
...en retry to start the solution, to see if this help.
In my experience sometime VS crash on start because there is an error in some source code, and due to that error VS can't compile the code, and then crash because without compiled code it's unable to show form in design mode.
In this case, deleti...
“CASE” statement within “WHERE” clause in SQL Server 2008
...
This should solve your problem for the time being but I must remind you it isn't a good approach :
WHERE
CASE LEN('TestPerson')
WHEN 0 THEN
CASE WHEN co.personentered = co.personentered THEN 1 ELSE 0 END

Multiple GitHub Accounts & SSH Config
...g file points to github.com and it doesn't know which key to use when it's time to do the pull.
So I found a trick with github.com. You can tell your ssh client that each repository lives in a different github.com subdomain, in these cases, they will be repo1.github.com and repo2.github.com
So fir...
Are std::vector elements guaranteed to be contiguous?
...s random access iterators. In addition, it supports (amortized)
constant time insert and erase operations at the end; insert and erase in the middle take linear time. Storage
management is handled automatically, though hints can be given to improve efficiency. The elements of a
vector are stor...

Python executable not finding libpython shared library

The best way I've found to address this is at compile time. Since you're the one setting prefix anyway might as well tell the executable explicitly where to find its shared libraries. Unlike OpenSSL and other software packages, Python doesn't give you nice configure directives...
When should a class be Comparable and/or Comparator?
...ompared.
With generics, you can declare so, and have it checked at compile-time. This improves safety, but it is also a challenge to determine the appropriate value.
As a guideline, I generally use the most general class or interface to which that object could be compared, in all use cases I envisi...
“Bitmap too large to be uploaded into a texture”
... About three and a half months now I have been programming almost full time on Android and I just now realized this. Seems dumb to make drawable essentially a hidden drawable-mdpi folder. This also explained why my custom map markers looked awful (they were being upscaled, then downscaled).
