"Welcome to the Unix Tree. Here you can browse the source code and manuals of various old versions of Unix. For every file, you can also find related files from other versions: this can help show how the different versions of Unix are related. Most of the Unix versions below come from the Unix Archive."

why GNU grep is fast
august 2010 by rtlechow
"I am the original author of GNU grep… Anyway, just FYI, here's a quick summary of where GNU grep gets its speed. Hopefully you can carry these ideas over to BSD grep.
#1 trick: GNU grep is fast because it AVOIDS LOOKING AT
EVERY INPUT BYTE.
#2 trick: GNU grep is fast because it EXECUTES VERY FEW
INSTRUCTIONS FOR EACH BYTE that it *does* look at."

Jiffy (time) - Wikipedia, the free encyclopedia
april 2010 by rtlechow
"Jiffy is used in different applications for various short, very short, or extremely short periods of time. In informal speech a "jiffy" means any unspecified short period of time, as in "I'll be back in a jiffy", but in other contexts it has more precise definitions. The word is thought to originally be thieves' cant for lightning, though this cannot be confirmed.[1]"

pwnat - NAT to NAT client-server communication
march 2010 by rtlechow
"pwnat, pronounced "poe-nat", is a tool that allows any number of clients behind NATs to communicate with a server behind a separate NAT with *no* port forwarding and *no* DMZ setup on any routers in order to directly communicate with each other. The server does not need to know anything about the clients trying to connect. Simply put, this is a proxy server that works behind a NAT, even when the client is behind a NAT, without any 3rd party. There is no middle man, no proxy, no 3rd party, no UPnP/STUN/ICE required, no spoofing, and no DNS tricks."

Resynthesizer
march 2010 by rtlechow
"Resynthesizer is a Gimp plug-in for texture synthesis. Given a sample of a texture, it can create more of that texture. This has a surprising number of uses:
* Creating more of a texture
(including creation of tileable textures)
* Removing objects from images
(great for touching up photos)
* Creating themed images
(such as the Resynthesizer logo above)
For details of the algorithm, see my PhD thesis. "

VIS - Thomas Müller
february 2010 by rtlechow
"Using todays high performance graphics hardware, we have developed a Qt application which enables the user to interactively explore the stellar sky in the vicinity of a Schwarzschild black hole. For that, we determine what an observer, who can either move quasistatically around the black hole or follow a timelike radial geodesic, would actually see."

Short Order Ruby - Ben Griffiths - Ruby Manor
december 2009 by rtlechow
"Ben once needed to send his colleagues a graph every week, based on some figures in a MySQL database. He thought the obvious way to do that was to create an ASCII bar chart, using Ruby (I like the use of “obvious”). When you change the pager in MySQL all the output from a query gets passed through the program that you specify (much like the pipe examples above). So here’s the chart (the bars are the wrong length – there’s only so fast a boy can type so I’ve blatantly added the bars in after the event):"

About | Scan Tailor
november 2009 by rtlechow
Scan Tailor is an interactive post-processing tool for scanned pages. It performs operations such as page splitting, deskewing, adding/removing borders, and others. You give it raw scans, and you get pages ready to be printed or assembled into a PDF or DJVU file. Scanning, optical character recognition, and assembling multi-page documents are out of scope of this project.

Uzbl - a browser that adheres to the unix philosophy.
september 2009 by rtlechow
Uzbl follows the UNIX philosophy - "Write programs that do one thing and do it well. Write programs to work together. Write programs to handle text streams, because that is a universal interface."
* very minimal graphical interface. You only see what you need
* what is not browsing, is not in uzbl. Things like url changing, loading/saving of bookmarks, saving history, downloads, ... are handled through external scripts that you write
* controllable through various means such as fifo and socket files, stdin, keyboard and more
* advanced, customizable keyboard interface with support for modes, modkeys, multichars, variables (keywords) etc. (eg you can tweak the interface to be vim-like, emacs-like or any-other-program-like)
* focus on plaintext storage for your data and configs in simple, parseable formats
* Uzbl keeps it simple, and puts you in charge.
