This document describes how to install Windows 98, Windows 2000, DOS and Linux using GRUB.* NEW entry
From cassette tapes to disk drives, the most popular way to store data is with magnetic materials. Yet exactly how individual magnetic bits reverse direction during writing and re-writing is still poorly understood. In the 22 January PRL a Canadian group reports the fastest and most spatially detailed movies of the flipping of micrometer-sized magnets. For the first time, the experiments reveal how the slow and complex flipping patterns of magnetic domains within a micromagnet can be coordinated and sped up with magnetic fields. The results help researchers better understand magnetic switching and may help designers optimize magnetic storage devices. (B. C. Choi et al., Phys. Rev. Lett. 86, 728.

For the first time, physicists in two separate laboratories have effectively brought a light pulse to a stop. In the process, physicists have accomplished another first: the non-destructive and reversible conversion of the information carried by light into a coherent atomic form. Sending a light pulse into specially prepared rubidium (Rb) vapor, a group at the Harvard-Smithsonian Center for Astrophysics led by Ron Walsworth (617-495-7274) and Mikhail Lukin (617-496-7611) has (1) slowed the pulse's "group velocity" to zero and (2) stored its information in the form of an atomic "spin wave," a collective excitation in the Rb atoms. (A spin wave can be visualized as a collective pattern in the orientation of the atoms, which spin like tops and hence act like tiny bar magnets. "Spin" is merely the name for the tiny magnetic vector in each of the atoms.) The atomic spin wave is coherent and long-lived, which enables the researchers to store the light pulse's information and then convert it back into a light pulse with the same properties as the original pulse.

description: This patch integrates SecurID authentication services directly into the OpenSSH daemon, allowing users to use SecurID tokens directly as their passwords instead of relying on the clunky sdshell.
description: Exmh is an X user interface for MH mail. MH provides a set of UNIX commands that manage folders and mail messages. MH has a zillion features as a result of several years of availability. Exmh provides a graphical interface to many of these features, as well as MIME, PGP/GPG support, NNTP, and more. changes: This release adds an flist patch for flaky NFS connections, improved support for POP mailserver access, a symlink attack fix, a fix for users of the auto-pack feature, various minor PGP fixes, support for direct procmail use (instead of slocal), undo for the sedit shell, and a filter to sedit (pipe a region through a Unix command).
description: Bashish is a theme-engine for bash and other shells (zsh, tcsh, rc, akanga, ksh and other POSIX-style shells) that will customize nearly all aspects of the terminal: title, colors, prompt, font, background, etc. With its scalable design, Bashish aims to create a developer- and user-friendly theme engine. changes: Font restore in X and app-theme bugs have been fixed. It is now possible to use 'aliases' instead of functions with app-themes. Debugging has been updated. bt/override and bt/default are now read upon app-theme changes.
Using scanning tunneling microscopy (STM) and first-principles local-spin-density-approximation calculations to study submonolayer films of Co_(1-c)Ag_c/Ru(0001) alloys, we have discovered a novel phase-separation mechanism. When the Ag concentration c exceeds 0.4, the surface phase separates between a dislocated, pure Ag phase and a pseudomorphically strained Co0.6Ag0.4 surface alloy. We attribute the phase separation to the competition between two stress relief mechanisms: surface alloying and dislocation formation. The agreement between STM measurements and our calculated phase diagram supports this interpretation.
Using a time-of-flight technique we have investigated the backscattering of 5 keV Ar2+ and Ar11+ projectiles from Au(110). A strong dependence on target azimuth is found for the neutral flux resulting from (quasi)binary projectile collisions with target atoms, while for the charged components only a weak dependence is seen. A deconvolution of the observed dependences based on trajectory simulations clearly shows site-specific neutralization differences between the various possible binary collisions occurring with surface atoms. Such differences must be properly accounted for in order to permit meaningful comparison with theory.

Molecular dynamics (MD) methods with a modified Tersoff potential have been used to simulate high-energy (50 keV) displacement cascades in β-SiC. The results show that the cascade lifetime is very short, 10 times shorter than that in metals, and the surviving defects are dominated by C interstitials and vacancies, which is similar to behavior for 10 keV cascades in SiC. Antisite defects are generated on both sublattices. Although the total number of antisite defects remaining at the end of the cascade is smaller than that of Frenkel pairs, the number of Si antisites is larger than the number of Si interstitials. Most surviving defects are single interstitials and vacancies, and only 19% of the interstitial population is contained in clusters. The size of the interstitial clusters is small, and the largest cluster found, among all the cascades considered, contained only four interstitial atoms, which is significantly different behavior than obtained by MD simulations in metals. It is observed that all clusters are created by a quenched-in mechanism directly from the collisional phase of the cascade to their final arrangements. The initial Si recoil traveled about 65 nm on average, generating multiple subcascades and forming a dispersed arrangement in the cascade geometry. These results suggest that in-cascade or direct-impact amorphization in SiC does not occur with any high degree of probability during the cascade lifetime of Si cascades, even with high-energy recoils, consistent with previous experimental and MD observations.

<Files htpasswd> order deny,allow deny from all </Files>を追加するのも忘れずに :-)
401 Blocker works by using a 401 error doc call (Bad Pass) to the script which logs the attempt's source IP address. If the script sees a configurable number of further bad password attempts in a certain timeframe, it rewrites the .htaccess file to block that IP permanently. Changes: Initial release.
Changes: Lots of bugfixes and improvements. See http://httpd.apache.org/dist/CHANGES_1.3 for details.
Changes: A new full screen curses based interface, typo analysis, a reorganized manual that is hopefully easier to follow, an expanded dictionary words found in the original ispell dictionary, and a switch to the multi-language branch of libtool have been added.
LinuxFromScratch is a project aimed at teaching the reader more about the inner workings of Linux. It's primarily intended for those seeking to learn more about how Linux works and how the various pieces of the Operating System fit together and interact, and for people who want to get away from existing distributions.

It's here. It's new. It's freshmeat II. (/me quits rhyming) -- Way too much time has passed since the last rewrite. The first baby-blue freshmeat went online Jan 1st 1999, more than 2 years ago. Here's baby-blue freshmeat II, codenamed 'Verdi'. Besides being completely restructured database wise to better cope with with the project data, this release incorporates most of the features users requested in the past months. Click the link for a quick rundown. Update: Yes, you convinced me the select boxes suck and as such they will be replaced with link icons as soon as I get a chance.
