Could not execute editor
...m. (Those were already in place.)
In my situation, the problem was solved by adding the -f flag to the vi command:
git config --global core.editor '/usr/bin/vi -f'
Once this -f option is in place, I can use git rebase -i, and when I save-and-exit the commit list, the rebase proceeds as it should...
What are file descriptors, explained in simple terms?
... be 100 entries in OS (somewhere in kernel). These entries are represented by integers like (...100, 101, 102....). This entry number is the file descriptor.
So it is just an integer number that uniquely represents an opened file in operating system.
If your process opens 10 files then your Process ...
Android SharedPreference security
...references are stored as a file in the filesystem on the device. They are, by default, stored within the app's data directory with filesystem permissions set that only allow the UID that the specific application runs with to access them. So, they are private in so much as Linux file permissions rest...

volatile was specifically intended to be used when inter...
Release generating .pdb files, why?
...e without the PDB files, it would be impossible to debug a "Release" build by anything other than address-level debugging. Optimizations really do a number on your code, making it very difficult to find the culprit if something goes wrong (say, an exception is thrown). Even setting breakpoints is ex...
How do I round to the nearest 0.5?
...
Multiply your rating by 2, then round using Math.Round(rating, MidpointRounding.AwayFromZero), then divide that value by 2.
Math.Round(value * 2, MidpointRounding.AwayFromZero) / 2

SQL “between” not inclusive
... "beginning of" or "the end of".
BETWEEN should be avoided when filtering by date ranges.
Always use the >= AND < instead
SELECT * FROM Cases
WHERE (created_at >= '20130501' AND created_at < '20130502')
the parentheses are optional here but can be important in more complex queries...
