Compiling LaTeX on Windows: An alternative method 2007-07-22 20:12:00 The usual method
to compile latex is by using "latex" command, and if the latex file contains bibliography, it will be a very tedious and repetitive job.To produce a dvi file:latex yourfile.texbibtex yourfile.texlatex yourfile.texlatex yourfile.texTo produce a pdf file:pdflatex yourfile.texbibtex yourfile.texpdflatex yourfile.texpdflatex yourfile.texHowever, for the windows user, with miktex, there is an alternative that could simplify all those tasks - the texify.To produce a dvi filetexify yourfile.texTo produce a dvi file and clean all the auxilary filestexify -c yourfile.texTo produce a pdf file (to clean all the auxilary files, just add -c as above)texify -p yourfile.texTo produce a dvi file and run the default viewer (add -p for pdf)texify yourfile.tex --run-viewer Read more:Windows

Backup folders with 7-zip command line 2007-05-23 20:24:00 The 7-zip command
line can be used to do a multiple folders backup. The good thing with 7-zip is that it support many compression method such as bzip2, gzip, zip and of course 7z.Here are steps for doing a backup on multiple folders on Windows: Download the 7-zip Command Line Version from Extract the content of the zip file to a temporary folder. Copy 7za.exe to your system folder (for example C:\Windows\System32\ for Windows XP).Create a folder for your backup, for example C:\backup. Create a text file in the C:\backup folder and name it backup.txt. List the full path of the folders that will be backup, each on a new line. Create a batch file in C:\backup folder and name it backup.bat. In the backup.bat file, type 7za u backup -up1q3r2x1y2z1w2 @backup.txtTo back up, just double click t
Python: Make division always produce real numbers 2008-03-28 04:35:00 A division of 7/2 in Python
will gives a result of 2. However, this is not correct. Since Python always
assume that the numbers are whole numbers, the resultant will be truncated from 2.5 to 2.A work around is to write one of the numbers as a decimal:>>> print 7/3.02.5>>> print 7.0/32.5>>> print 7.0/3.02.5In order to change this behaviour of Python, throughout the program execution, so that Python will always produce
real numbers, a module division has to be imported.>>> from __future__ import division>>> print 7/32.5
