Python and a GIL

I run recently into a very nice article that describes in an excellent way of what a GIL is and what it is not. So if you, as me run in to many GIL battles in your life, it is a good read. One thing to add, traditionally threads were introduced to do a parallel IO not a parallel computation, keep that in mind.

UTF8 support under Windows in SublimeText2

SublimeText2 has a great problem with guessing encoding under Windows system. It tries to use CP1252 instead of CP1250 (for my locals:)) by default. I strongly suggest installing a package manager for SublimeText2. And then installing a encoding helper plugin. I also recommend (If you are a Central-European nation) changing a fallback_encoding property in: Preferences->Settings- Default to a Central European (Windows 1250).
A list of possible values:
st_encodings_list = [
   "UTF-8 with BOM",
   "UTF-16 LE",
   "UTF-16 LE with BOM",
   "UTF-16 BE",
   "UTF-16 BE with BOM",
   "Western (Windows 1252)",
   "Western (ISO 8859-1)",
   "Western (ISO 8859-3)",
   "Western (ISO 8859-15)",
   "Western (Mac Roman)",
   "DOS (CP 437)",
   "Arabic (Windows 1256)",
   "Arabic (ISO 8859-6)",
   "Baltic (Windows 1257)",
   "Baltic (ISO 8859-4)",
   "Celtic (ISO 8859-14)",
   "Central European (Windows 1250)",
   "Central European (ISO 8859-2)",
   "Cyrillic (Windows 1251)",
   "Cyrillic (Windows 866)",
   "Cyrillic (ISO 8859-5)",
   "Cyrillic (KOI8-R)",
   "Cyrillic (KOI8-U)",
   "Estonian (ISO 8859-13)",
   "Greek (Windows 1253)",
   "Greek (ISO 8859-7)",
   "Hebrew (Windows 1255)",
   "Hebrew (ISO 8859-8)",
   "Nordic (ISO 8859-10)",
   "Romanian (ISO 8859-16)",
   "Turkish (Windows 1254)",
   "Turkish (ISO 8859-9)",
   "Vietnamese (Windows 1258)",

PowerShell sending requests

From time to time, I have to generate a request to some web service for each element from a database. From a db I tend to generate a PowerShell commands to send a request:
$page = (New-Object System.Net.WebClient).DownloadString("http://localhost/")
And if one needs to know what was returned
Write-Host "$page"

Using PowerShell

I still keep using Unix tools underneath my GNU Emacs on windows, tools, like grep, sort, find. But, they need a configuration, and on Windows, they face specific problems :) On SO, there is a nice list of PoSh cmdlets that are an excellent replacement for my typical tasks.

The next JavaScript issue

This site becomes my diary of JavaScript problems that I fall into, or am aware of. The newest one is the infinity. In other words what is a result of:
parseInt(1 / 0, 19)
And why it is 18.

What tool use to write T4 templates

Each time, I work for a different company, I use a different tool, so far I believe the best is tangible t4, without modeling tools.
