Floating point constants should have the available highest precision. The result can be assigned to a float without undue trouble.

`subprocess.Popen` replaces the group of `os.popenX` POSIX functions (which have a long history). I suppose that the name `Popen` makes it more likely for people used to the old functions to find and use the new ones. The [PEP for subprocess (PEP 324)](http://www.python.org/dev/peps/pep-0324/) has a little bit of disc...

Hm, [Rockford Lhotka](http://www.lhotka.net/) sad, that LINQ to SQL is wonderful technology for fetching data from database. He suggests that afterwards they'll must to be bind to "reach domain objects" (aka. CSLA objetcs). Seriously speaking, LINQ to SQL had it's support for n-tier architecture see method.

The ps is a really poor way of doing that and probably open to race conditions. The traditional Unix/Linux way would be to write the PID to a file (typically in /var/run) and check to see if that file exists on startup. e.g. the pidfile being located at /var/run/myscript.pid then you'd check to see if that exists bef...

Mark's answer is the way to go, after all, that's why the /proc file system is there. For something a little more copy/pasteable: ``` >>> import os.path >>> os.path.exists("/proc/0") False >>> os.path.exists("/proc/12") True ```

``` celsius = (5.0/9.0) * (fahr-32.0); ``` In this expression, `5.0`, `9.0`, and `32.0` are `double`s. That's the default type for a floating-point constant - if you wanted them to be `float`s, then you would use the `F` suffix: ``` celsius = (5.0F/9.0F) * (fahr-32.0F); ``` Note that if `fahr` was a `double`, then...

Now, I'm not saying that this is the greatest name in the world, but here was the idea as I understand it.

The reason that the expression is cast to double-precision is because the literals specified are double-precision values by default. If you specify the literals used in the equation as floats, the expression will return a float. Consider the following code (Mac OS X using gcc 4.01). ``` #include <stdio.h> int main(...

Honestly? I've never found a use for staticmethod or classmethod. I've yet to see an operation that can't be done using a global function or an instance method.

I recently "needed" a zip function in Perl 5 (while I was thinking about [How do I calculate relative time?](https://stackoverflow.com/questions/11/how-do-i-calculate-relative-time)), i.e. a function that takes two lists and "zips" them together to one list, interleaving the elements. (Pseudo)example: ``` @a=(1, 2, ...
Is there an elegant zip to interleave two lists in Perl 5?

I need to `query` an Exchange server to find all messages having a certain value in `PR_SEARCH_KEY`. Do I have to open every mailbox and iterate through it or is there a faster solution?

> TrueType Fonts (TTF) will generally work on Windows, Mac, and Linux platforms. Thanks Jason, but this isn't the answer I'm looking for. Many Linux distributions come with their own fonts that are different to the Mac/Windows versions - presumably because of font licensing issues. I'd like a response from a Linux u...

Any DVCS would likely work fine. My favorite is [Bazaar](http://bazaar-vcs.org/). It would be easiest to keep your config files in .config, version that, and then symlink as appropriate. A benefit of DVCS is that you can version the per-machine config files as well, without interfering with versioning global configs.

This would be an interesting project (has anyone done it already?) I presume you'd give the tool your jar(s) as a starting point, and the library jar to clean up. It could use reflection to determine which classes your jar(s) reference directly, and which are used indirectly down the call tree (this is not trivial at...

Version control software isn't really great for home directories. Worse, some software doesn't really like the .svn folders or starts to interpret their contents. You could of course try to fix this with some very complex mirroring setup, but that's hard.

Seems odd to me why you'd want to store the same object both server side and client side - especially if you're comparing them on each trip. I'd guess that deserializing the cookie and comparing it to the server side object would be equivalent in performance to just serializing the object again. But, if you wanted to...
