Is there a way to “autosign” commits in Git with a GPG key?
...should be GPG signed.
Use of this option when doing operations such as rebase can result in a large number of commits being signed. It may be convenient to use an agent to avoid typing your GPG passphrase several times.
That config is usually set per repo (you don't need to sign your private e...
background function in Python
...to do in the background, this can be either better or worse than threading-based solutions; certainly, it is much more scaleable (ie you can do many more things in the background), but that might not be of concern in the current situation.

Multiple queries executed in java in single statement
... possible. There are two ways, as far as I know. They are
By setting database connection property to allow multiple queries,
separated by a semi-colon by default.
By calling a stored procedure that returns cursors implicit.
Following examples demonstrate the above two possibilities.
Example 1...
Storing DateTime (UTC) vs. storing DateTimeOffset
...ly have an "interceptor" that right before reading/writing from/to the database does DateTime conversion (from UTC to local time, and from local time to UTC), so I can use DateTime.Now (derivations and comparisions) throughout the system without worrying about time zones.

enum.values() - is an order of returned enums deterministic
...ld for each planet. Then you can have a trivial comparator compare planets based on their mean distance from Sun, and order them using this comparator. This is IMHO a clean and foolproof solution. Whereas your solution breaks as soon as e.g. a new colleague decides that planets should obviously be l...
parseInt vs unary plus, when to use which?
...ail since the x and e are treated as non-numerical components (at least on base10).
The unary + will convert them properly though.
parseInt('2e3',10) === 2; //true. This is supposed to be 2000
+'2e3' === 2000; //true. This one's correct.
parseInt("0xf", 10) === 0; //true. This is s...
Set default syntax to different filetype in Sublime Text 2
...
You can turn on syntax highlighting based on the contents of the file.
For example, my Makefiles regardless of their extension the first line as follows:
#-*-Makefile-*- vim:syntax=make
This is typical practice for other editors such as vim.
However, for t...
filter items in a python dictionary where keys contain a specific string
...u can use the built-in filter function to filter dictionaries, lists, etc. based on specific conditions.
filtered_dict = dict(filter(lambda item: filter_str in item[0], d.items()))
The advantage is that you can use it for different data structures.

Why is there no Constant feature in Java?
...005, the "const" topic was vigorously debated:
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=4211070
While there are a lot of good arguments on both sides, some of the oft-cited (but not necessarily compelling or clear-cut) reasons against const include:
may have confusing semantics that ma...
Is the creation of Java class files deterministic?
...not matter. However, we find it beneficial to have javac's output not vary based on implementation details of system classes .
This pretty clearly illustrates the issue: The compiler is not required to act in a deterministic manner, as long as it matches the spec. The compiler developers, however,...
