Tulip is a software system dedicated to the visualization of huge graphs. It manages graphs with up to 500,000 elements (node and edges) on a personal computer (PIII 600, 256MB RAM). Its SuperGraph technology architecture provides the following features: 3D visualizations, 3D modifications, plugin support, support for clusters and navigation, automatic graph drawing, automatic clustering of graphs, automatic selection of elements, and automatic coloring of elements according to a metric.
When newer clients than 2.8000 connect to the proxy, their packets are stripped off from their identity. Taken from http://www.distributed.net/download/proxies.html: ---cut build 311 (Nov 16th 1999) Do not attempt to flush blocks produced by client versions v2.8000+ through a personal proxy older than build 311 (directly or through a chain of proxies). You will lose the email, cpu, id, and version associated with any completed blocks. ---cut Due to the nature of a proxy, many different and often much newer clients connect to the proxy - and all their work for rc5stats.distributed.net is lost.そ、そうだったのか。

The number perl script will print the English name of a number. One can print names of extremely large numbers (e.g. 1e1234567). Number can be run on the command line, or as a CGI script when run as 'number.cgi'. Number prints names in both the American and European naming system. It can also print the decimal expansion of a number in either naming system.ひひひ。

SGMLtools-Lite is the successor of SGMLtools. It is a set of Python and DSSSL scripts which makes interaction with Jade in order to process (mostly DocBook) SGML files a breeze, and is easy to extend with custom processing instructions. Out of the box, SGMLtools-Lite knows how to convert DocBook to HTML (2 styles), JadeTeX, DVI, RTF, PS, PDF, plain text, and PalmOS iSilo format. It also comes with a conversion script to convert "old" LinuxDoc documents to DocBook. Changes: An update to the Red Hat 7.1 spec file to handle stylesheets-dsssl location.
dvipdfm は DVI から PDF へ変換するユーティリティです。 欧文の Type 1 フォントへの対応はだいぶできているようですが、そのままでは日本語を取り扱えません。 昔、PDFlib を使って perl で DVI -> PDF の変換を行なうスクリプトを作ったのですが、 PDFlib はこの目的には向いておらず、結局、dvipdfm を何とか日本語を通すようにする事にしました。
Case: (大文字・小文字を表す場合は) 活字ケースのこと。 その昔、活字を「箱」に入れて管理していた頃、大文字を集めた箱と小 文字を集めた箱は別の箱になっていて、upper case は上段に、lower case は下段に格納されるのが一般的だった。
SMBAuth provides an Apache module and commandline binary for authenticating users with an SMB Domain. This could be an NT domain controller or SAMBA on Linux. Other tools exist for this, but this was written to provide a simpler setup.
Squid Graph is a powerful logfile analysis tool for native Squid version 2 logfiles. It generates HTML reports and graphs of accesses, transfers and transfer durations, somewhat similar to MRTG. Changes: Squid Graph has been completely re-written. It now generates HTML reports with image graphs, TCP and UDP data are now seperately (and accurately) analyzed giving three different graphs -- graph of accesses, graph of transfers, and graph of average transfer duration, and a lot of other noticable changes.
The scaling properties of the maximal height of a growing self-affine surface with a lateral extent L, are considered. h*_{L}, its value measured from the evolving average height, scales like the roughness as $L^{\alpha}$ in the late-time regime. In this regime its distribution has a leading decay at large values like $\exp\{A({h*_{L}}/L^{\alpha})^{a}\}$. In the early-time regime, in which the roughness grows as $t^{\beta}$, the maximal height grows, to the leading behavior, as $t^{\beta}[\ln{L}-({\beta\over \alpha})\ln{t} + C]^{1/b}$, where either b=a or b is the corresponding exponent of the late-time velocity distribution. These properties, obtained from scaling and extreme-values arguments, are corroborated by numerical simulations, and supported by exact results for surfaces in 1D with asymptotic behavior of Brownian paths.
The scaling behavior of cyclical growth (e.g. cycles of alternating deposition and desorption primary processes) is investigated theoretically and probed experimentally. The scaling approach to kinetic roughening is generalized to cyclical processes by substituting the time by the number of cycles $n$. The roughness is predicted to grow as $n^{\beta}$ where $\beta$ is the cyclical growth exponent. The roughness saturates to a value which scales with the system size $L$ as $L^{\alpha}$, where $\alpha$ is the cyclical roughness exponent. The relations between the cyclical exponents and the corresponding exponents of the primary processes are studied. Exact relations are found for cycles composed of primary linear processes. An approximate renormalization group approach is introduced to analyze non-linear effects in the primary processes. The analytical results are backed by extensive numerical simulations of different pairs of primary processes, both linear and non-linear. Experimentally, silver surfaces are grown by a cyclical process composed of electrodeposition followed by 50% electrodissolution. The roughness is found to increase as a power-law of $n$, consistent with the scaling behavior anticipated theoretically. Potential applications of cyclical scaling include accelerated testing of rechargeable batteries, and improved chemotherapeutic treatment of cancerous tumors.

Magnetic field lines do not like to bend. When you try to press two magnets together the wrong way, you feel this tendency directly--the field lines resist being squashed to the sides. This magnetic "tension" may have surprising effects when space itself warps, according to a paper in the 11 June PRL. The author finds that when spacetime bends in response to matter, the magnetic field lines push back and try to flatten spacetime. This "magnetocurvature" effect would be strongest when spacetime is most strongly curved--near neutron stars and black holes, and in the very early Universe. Magnetocurvature effects might be measurable in gravitational radiation reaching Earth; they also seem to exclude some theories of the Universe's earliest moments.( Christos G. Tsagas, Phys. Rev. Lett. 86, 5421. )
Listen to your radio on a long car trip, and you'll hear the signal become garbled by noise on competing frequencies. Frequency competition is not just a problem for receiving signals: Microwave sources used in telecommunications produce extra frequencies that compete with the broadcast frequency. A paper in the 11 June PRL details a new way to squash the competition using a so-called photonic band gap structure. The periodic array of rods may be the best way to create narrow, high-frequency microwave signals for everything from satellites to cell phones.( J. R. Sirigiri et al., Phys. Rev. Lett. 86, 5628. )

afbackup is a client-server backup system allowing many workstations to backup to a central server either simultaneously or serially. Backups can be started remotely from the server or via cron jobs on the the clients. Any streaming device, including a drive partition acting as a "virtual" tape changer, can be used for storing data. Autochangers can be used, if an appropriate auxiliary program, such as mtx or stctl, is available and working. afbackup has been tested on Linux, AIX, IRIX, FreeBSD, Digital Unix (OSF1), Solaris and HP-UX. The clientside has also been tested on SunOS and OpenBSD. Changes: This release contains bugfixes and major improvements.

Changes: A fix for a potential buffer overflow in the string handling library.
Is it a liquid, a solid, or a gas? That question puzzles physicists studying the collective motion of small particles--such as sand-- because granular materials can act in ways similar to all three states of matter. In a simple experiment presented in the 25 June PRL, researchers observed sand sliding down a rough slope and saw the first example of spontaneous vortices forming in granular matter. Their analysis reveals that sand can display characteristics of both a liquid and a gas simultaneously. The result may help geophysicists make better models and draws a crucial connection between liquid and gas behavior in granular systems.( Y. Forterre and O. Pouliquen, Phys. Rev. Lett. 86, 5886. )
Researchers have put a rubbery polymer under the control of a dimmer switch: Lights up, and the material contracts; lights down, and it re- expands. Their soft, tacky prototype shortens 25% in one dimension, while fattening in the others, and it adjusts its shape over tens of minutes, according to a 2 July PRL report. If chemists can make successor compounds that morph more speedily, they might provide micromachines with valves and robots with muscles.( H. Finkelmann et al., Phys. Rev. Lett. 86, 015501. )
