Stuff from Márton Balázs

These pages are outdated. Me and my webpage have moved to Bristol.

Some stuff I think are useful

Mathematics
- Probability 1 lecture notes for mathematician and physicist students (in Hungarian, joint with Bálint Tóth)
- Reminder of some basic theorems in probability (in Hungarian)
- I once computed the density of the sum of n independent exponential random variables, each with different parameters.
- My favorite calculus function (nose function)
- My PhD
- Undergraduate works
Computer (linux/unix, for most cases, feel free to use at your own risk!!)
- My .bashrc, my .vimrc, my .vimperatorrc, my .pentadactylrc.
- Text, tex, html processing
  - Animated PDF
  - Plotting elementary functions in PSTricks: the source of the nose function.
  - How to split a dvi file to the contents and the references?
  - \'a or á? &aaucte; or á? (in Hungarian)
  - This one sorts lines of a file alphabetically (needs the point-keeping stuff), while this guy shuffles them.
  - Creates a random lowercase string of a given length; creates a random directory named date plus a random string of a given length.
  - This one here compiles all the latex files in the directory.
- Document utilities
  - Converts a LaTeX file into PDF, into PS. Use it without file extension.
  - Two-sided printing. Sends a PS file to the printer in two parts. What comes out first should be turned upside-down within the horizontal plane (except for landscape pages), then hit [Enter]. Best used with PsBind.
  - Document viewer. Tries to open all types of documents in the current directory that have the given string in their names. Opens all files if receives * as parameter.
  - Document editor. Copies some types of documents with the given string in their filenames into a new directory, opens them, compiles them if needed (eg. LaTeX), opens the results as well. The files are moved back to their original place when editing is finished. Saves manual opening, compiling and clean-up. It assumes an existing ~/tmp/ directory.
- Class points-keeping
  - How to keep track of students' points in LaTeX?
  - And here is how to do it more elegantly under Linux/Unix (in Hungarian).
- Media processing
  - With ImageMagick: removes exif data, cuts size to half, cuts quality to half, almost destroys quality, rotates to the right, rotates to the left, rotates upside down files in the current directory. Of course makes sense if files are actually pictures.
  - Once I even figured how to rotate an AVI video.
- File processing
  - This one cleans up after LaTeX files. Without an argument, all LaTeX files. With an argument, only that given as parameter.
  - This one extends filenames in a directory by a dashline. And this one takes it back.
  - This guy has a directory as input (default is /tmp/). It compares all files in the current directory to those in the input directory, and lists those in the local dir which are no match. Filenames don't matter, it uses cmp.
  - This guy has a directory as input. It compares all files in the current directory to those in the input directory, and separates them according to the result of the comparison. The ones that differ are also opened in vimdiff.
  - This one has two inputs: a directory and a file name. It searches recursively from the given directory files of which the names contain the words listed in the input file. If found, it links the file into the current directory. If found more than one, it asks.
  - These copy or move the files given in their arguments to a new randomly named dir in ~/tmp.
- Miscellaneous
  - This one prints the date (yy.mm.dd), time, and weather. Weather refresh intervals can be set. It has been designed to use with the gltext screensaver.
  - It happens a million times that you just need yet another terminal in the current directory. This opens one.
  - This one here hangs until Dropbox says "Idle" three times with 1 sec differences. I use it to make sure no other synchronization script starts before Dropbox finishes.
  - This here hangs until the CPU usage drops below 30%. I don't like overloading the system by starting a lot of things together. (Credits go to Paul Colby.)
