rpm-get is a simple clone of apt-get for rpm. Changes: This release fixes the very nasty bug in the previous version that allowed the program to overwrite some of the root file system. All remove commands have been removed, and no function that removes the cached files will be implemented until it's a 100% certainty that it won't cause any harm.

With cinfo you can find out how much of a file is already resident in memory. This is useful if you want to figure out if your server could do with more memory to improve caching behaviour. License: GNU General Public License (GPL)
euc2html is a simple application to convert any double-byte Japanese (and maybe Chinese/Korean) EUC-encoded characters to HTML/4.0 Unicode entities. It operates using stdin/stdout only, so is useful for batch updating Web sites, content, etc. License: GNU General Public License (GPL)ふむ。
yptransitd is a versatile Unix daemon which provides NIS services with a modular backend interface. The current focus is the development of a backend LDAP module, providing for migration from standard NIS services to LDAP. Changes: Basic support of YP match calls were implemented to allow for user login.PAM の LDAP モジュール使えば、 win2k の Active Directory と組み合わせて認証を統一したりできるのかしらん。

How to use SSH and the Java-based program MindTerm to create quick, secure, and reliable VPN-like tunnels over insecure networks.* NEW entry
The output from this Perl code is a PostScript program that will produce a "map" of the directory tree for a UNIX (or Windows NT or 95/98) directory down to any level.PostScript を吐いてくれる。
rpmlint is a tool to check common errors on RPM packages. It's designed to check Linux Mandrake packages but it works with all RPM packages.
SciGraphica is a scientific application for data analysis and technical graphics. It pretends to be a clone of the popular commercial application "Microcal Origin", supplying plotting features for 2D, 3D, and polar charts. It features opening several worksheets and plots to work with at the same time, fully-configurable plots using a control panel dialog, a completely WYSIWYG look and feel, and publication-quality PostScript output. Changes: Ability to embed images and set background images for the plots, a clipboard for plots and images, improved PostScript and WYSIWYG, inclusion of pysga.py (a Python module for interacting with plots and worksheets from the terminal), a new scheme for storing numerical data in worksheets, and included examples.

tcptraceroute is a traceroute implementation using TCP SYN packets, instead of the more traditional UDP or ICMP ECHO packets. In doing so, it is able to trace through many common firewall filters.
This document describes installing the BIND 9 nameserver to run in a chroot jail and as a non-root user, to provide added security and min imise the potential effects of a security compromise. Note that this document has been updated for BIND 9; if you still run BIND 8, you want the Chroot-BIND8 HOWTO instead.* updated (new document; old name)
This document describes installing the BIND 8 nameserver to run in a chroot jail and as a non-root user, to provide added security and min imise the potential effects of a security compromise. This version of the document covers the old but still popular BIND 8; there is another document which provides similar information for BIND 9.* updated (old document; renamed)
Changes: This is a maintenance release. It contains fixes for a number of bugs in 9.1.2, but no new features.
Cablinux makes a Microsoft cabinet file from a set of input files. Changes: cablinux.c was split into smaller C source code files.
8640 万個の玉があります。 そこから１つひいてもどす、を 300 万回繰り返して 一回も同じ玉を引かない確率が知りたいのですが。まず N=8640万、n=300万とすると、 式としては
N N-1 N-2 N-n-1 N!
P = - x --- x --- … ----- = ----------
N N N N N^n (N-n)!
ということになる。
N! 〜 (2πN)^0.5 N^N exp[-N + 1/(12N) + …]を利用、exp の中は最初の -N だけを使う。
log P 〜 0.5 log(2π) + (N+0.5)log N - N
- [0.5 log(2π) + (N-n+0.5)log(N-n) - (N-n)]
- n log N
となる。0.5 は面倒くさいので無視して整理すると
log P 〜 (N-n)[log N - log(N-n)] - nとなる。
log(N-n) = log N(1-n/N) = log N + log(1-n/N) 〜 log N - n/Nだから (最後の近似は (x<<1) での log(1-x)〜-x を利用)、
log P 〜 n(N-n)/N - n = -n^2/Nになる。
P 〜 exp(-n^2/N) 〜 10^[-n^2/(N log10)] 〜 10^[-45289]ということになるようです。まあ直感の通りですが事実上 0 ですね。 逆に言うと n〜��N くらいまでなら重ならない確率も結構高いということか。
ddclient is a Perl client used to update dynamic DNS entries for accounts on Dynamic DNS Network Services' free DNS service.
The ESP Package Manager (EPM) is a simple tool that generates software and
patch distributions in various formats, including AT&T software packages
("pkg") used by Solaris, Debian ("dpkg"), HP-UX software packages
("swinstall" or "depot"), IRIX Software Manager ("inst" or "tardist"),
portable (installation and removal scripts with tar files), and Red Hat
Package Manager ("RPM").
AutoDia is a Perl application designed to allow the easy creation of XML diagrams from various data sources. The output is meant for use with Dia (or any XML parser). AutoDia supports any language through the use of handlers, and a good handler for Perl as well as a simple handler for C++ are included. Changes: Fixes for a couple of critical bugs in handling directories, a new C++ handler, new templates that provide quick and easy HTML API documentation, and improved/updated documentation.暇ができたら Fortran 用の parser でも書いてみるかな、と。
Unison is a file-synchronization tool for Unix and Windows. It allows two copies of a collection of files and directories to be stored on different hosts (or different disks on the same host), modified separately, and then brought up to date by propagating the changes in each replica to the other. Unison can deal with updates to both replicas of a distributed directory structure. Updates that do not conflict are propagated automatically. Conflicting updates are detected and displayed. Unison can communicate through a direct socket link or through an rsh/ssh tunnel. It uses network bandwidth efficiently. Changes: This beta release introduces three major new features: much faster update detection on Windows, local archiving of old versions of files, and file-level merging in case of conflicts, using an external merge program of the user's choice (ediff, vdiff, etc.).
round() だの floor() だの ceil() だのの関数は bits/mathcalls.h で定義さ れているようですが、floor() とかと違って round() は __USE_ISOC99 が define されていないと定義されないようになっているようです。 なんじゃこりゃ bits/mathcalls.h のバグか？と私も思ったのですが、よくよく 調べてみると round() は XOPEN とかでは定義されていない C99 から定義され た関数みたいです。 なので、結論としては普通に gcc 使ってて round() が定義されないのは正常な 動作であると思われます。 結構普通に使ってたりしましたが、実は標準化されていなかったのですね！ # gcc 3.x で gcc -std=c99 とかやれば round() もちゃんと使えるのでしょう。
This document is both a tutorial and a reference on shell scripting with Bash. It assumes no previous knowledge of scripting or programming, but progresses rapidly toward an intermediate/advanced level of instruction. The exercises and heavily-commented examples invite active reader participation. Still, it is a work in progress. The intention is to add much supplementary material in future updates to this document, as it evolves into a comprehensive book that matches or surpasses any of the shell scripting manuals in print.* updated; this is now a GUIDE
