The ShipIt project by Canonical (the Company behind Ubuntu Linux) was true: yeasterday a big package with 10 CD with Ubuntu Linux 6.06 Dapper Drake was arrived to me. 8 for x86 1 for AMD64 and EM64T 1 for G3, G4, G5 The package contains also 12 Ubuntu “linux for human beings” stickers. Thanks to Canonical!
I Google Labs si sono decisi: hanno rilasciato SketchUp e Google Earth per MacOSX. Il primo era sin ora disponibile solo in versione “PRO” mentre il secondo non era Universal Binary. C’è inoltre da evidenziare che GEarth é ora disponibile nativamente anche per Linux: qui la situazione, sin ora, era peggiore, con una versione di prova rilasciata per girare in Wine (tristissimo :P ). Sembra quindi che Google abbia mantenuto tutte le promesse, volendo coprire almeno tutta la “TRIADE” dei sistemi più diffusi. ...
Obviously, based on linux ;) An easy and simple interface. Poor and feature-less programs. Big-Chars interface. Usefull for old-boy with no interest to learn “new-techs”. It’s an Italian project. Check it out. Source, Downloadblog.
After the coronation as the best (imho ;) ) file-system for *nix systems, BitUbique post an howto defragment an XFS partition. Simplest and fastest way? sudo xfs_fsr -v /dev/hda1
IBM publish another Tutorial on the LPI Exam 202. This time it’s on the “making of a Web Server” (title “Web Services” is not correct, IMHO). In this tutorial (the fourth in a series of seven tutorials on exam 202 topics), David Mertz discusses how to configure and run the Apache HTTP server and the Squid proxy server, and in doing so, continues preparing you to take the Linux Professional Institute Intermediate Level Administration (LPIC-2) Exam 202. ...
Nemo translated (in Italian, of course) an interesting comparison between the most diffused filesystems on Linux (and not only on The Penguin): Ext2/3, Reiserfs 3, XFS, JFS. The original article was posted by hansivers on the Debian Administration Website. Conclusion? XFS rulez!!! And I’m on the same: I start to use XFS average 2 years ago… and some big partitions on my HD still demonstrate optimal performance. Good Job, SGI!
The 2.6 Linux Kernel included selectable IO schedulers. IO Schedulers control the way the kernel commits reads and writes to disks - the intention of providing different schedulers is to allow better optimsation for different classes of workload. Without an IO scheduler, the kernel would basically just issue each request to disk in the order that it received them. This could result in massive thrashing of the disk subsystem - if one process was reading from one part of the disk, and one writing to another, it would have to seek back and forth across the disk for every operation. The schedulers main goal is to optimise disk access times. An IO scheduler can use the following techniques to improve performance: Request merging The scheduler merges adjacent requests together to reduce disk seeking Elevator The scheduler orders requests based on their physical location on the block device, and it basically tries to seek in one direction as much as possible. Prioritisation The scheduler has complete control over how it prioritises requests, and can do so in a number of ways All IO schedulers should also take into account resource starvation, to ensure requests eventually do get serviced!… ...
Take a look at the ext2 (second extended file system), ext3 (third extended file system), and Reiser4 file systems and discover how to create your own Reiser4 file system. The most commonly used file system, ext2, is a traditional UNIX®-style file system that doesn’t mix well with modern hard drive sizes. The ext3 file system adds journalling, but not much else. If you want something really advanced, you might want to check out the current Reiser4 file system. ...
Treviño segnala a OSSBlog, e noi riprendiamo felicemente che è stata finita la traduzione completa della guida italiana ad Ubuntu Breezy. ...
Red Hat, finally, opens its Knowledgebase: Red Hat Knowledgebase is a library of tips, troubleshooting advice, and current information updated daily by Red Hat technicians. A “sink without bottom” (translation of the italian meaning-full expression “pozzo senza fondo”) of sources, knowledge, solutions about Linux. Source, OSSBlog.
