vellorean writes "I have been reading Linux Shell Scripting Cookbook by Sarath Lakshman, published by Packt, for a while. While most people I know learn shell scripts themselves, I was looking to refresh my concepts a little as well as have a reference lying around on the table for fast access." Read below for the rest of vellorean's review.

autospa points out a post (with video) showing off the multi-tasking abilities of the Blit terminal, developed in 1982 by Rob Pike and Bart Locanthi. Before Windows, before X, and before the Mac (but somewhat later than the Xerox Alto), the Blit terminal provided a multitasking, mouse-driven graphical interface; it took a Unix server on the other side to do the heavy lifting, though.

linuxwrangler writes "It's used in Java. It's used in nearly every flavor of UNIX/Linux. In PostgreSQL, Oracle and other databases. Several RFCs refer to it. But where does the timezone database come from? I never gave it much thought but would have assumed that it was under the purview of some standards body somewhere. It's not. Since the inception of the database Arthur David Olson has maintained the database, coordinated the mailing list and volunteers and provided a release platform and now he is retiring. IANA is developing a transition strategy. Jon Udell has an interesting literary appreciation of the timezone database."

doperative writes "A consultant hired by SCO in 2004 to compare UNIX and Linux, with the thought he could be used as an expert at trial, says that, after days and days, his comparison tool found 'very little correlation'. When he told that to SCO, it paid him and he never heard from SCO again."

snydeq writes "Deep End's Paul Venezia questions whether server virtualization technologies are contributing to the decline of real server administration skills, as more and more sysadmins argue in favor of re-imaging as a solution to Unix server woes. 'This has always been the (many times undeserved) joke about clueless Windows admins: They have a small arsenal of possible fixes, and once they've exhausted the supply, they punt and rebuild the server from scratch rather than dig deeper. On the Unix side of the house, that concept has been met with derision since the dawn of time, but as Linux has moved into the mainstream — and the number of marginal Linux admins has grown — those ideas are suddenly somehow rational.'"

GMGruman writes "It's a persistent myth: reboot your Unix box when something goes wrong or to clean it out. Paul Venezia explains why you should almost never reboot a Unix server, unlike say Windows."

snydeq writes "Deep End's Paul Venezia offers a field guide to understanding your resident Unix veteran, laying out the nine traits common to this grizzled, hardcore set. From not using sudo, to wielding regular expressions like weapons, to generally assuming the problem resides with whomever is asking the question, each trait is key to 'spotting these rare, beautiful creatures in the wild,' Venezia writes. 'If some of these traits seem anti-social or difficult to understand from a lay perspective, that's because they are. Where others may see intractable, overly difficult methods, we see enlightenment, borne from years of learning, experience, and overall, logic.'"

Evil-G writes "In an email on Friday, SCO informed its partners that UnXis Inc. was chosen as the successful bidder for SCO's Unix software business on 26 January. The slightly convoluted phrasing is probably due to SCO's current reorganization under Chapter 11. On 16 February, the transaction is to be submitted for approval to the bankruptcy court where SCO's case is pending."

Wired reports that it has confirmed a password flaw affecting some Amazon accounts. If your password hasn't been changed in a while ("the past several years"), it may be less secure than you'd like. As Wired explains, for these older accounts, "[...] if your password is “Password,” Amazon.com will also let you log in with 'PASSWORD,' 'password,' 'passwordpassword,' and 'password1234.'" The article suggests that Amazon's use of the Unix crypt() tool may be at fault. (Hat tip to E. Maureen Foley for pointing this out.)

jbrodkin writes "The inventors of Unix and the C programming language, one of whom also created the first master-level chess-playing machine, have been awarded the prestigious Japan Prize for their work in building the Unix operating system in 1969. Ken Thompson, who is now a distinguished engineer at Google, and Dennis Ritchie, who is retired, were researchers at Bell Labs four decades ago when they 'developed the Unix operating system which has significantly advanced computer software, hardware and networks over the past four decades, and facilitated the realization of the Internet,' the Japan Prize Foundation said Tuesday in awarding them the 2011 prize. The pair join previous winners such as Vint Cerf and Tim Berners-Lee. In addition to developing Unix, Thompson also played a key role in building Belle, the first chess-playing computer to achieve a master-level rating and five-time winner of the now-defunct North American Computer Chess Championship in the 1970s and 1980s. Ritchie and Thompson have also been credited with developing the C programming language, a process that occurred in conjunction with the development of Unix."

A great number of people wrote in to note that it's EPOCH Day 15000, so don't expect the post office to run, and I'm pretty sure the markets will be closed. And presumably your employer gave you a paid vacation day?

PerlDudeXL writes "Today, after almost two years of work, we have the special pleasure of announcing the much awaited release of Xfce 4.8, the new stable version that supersedes Xfce 4.6. [..] Xfce 4.8 is our attempt to update the Xfce code base to all the new desktop frameworks that were introduced in the past few years. We hope that our efforts to drop pieces like ThunarVFS and HAL with GIO, udev, ConsoleKit and PolicyKit will help bringing the Xfce desktop to modern distributions."

Kainaw writes "This was asked in 2005 and 2008. I think it should be revisited yet again... With iPhone, Android, and Windows smartphones running around, which (if any) of them are well-suited to Unix/Linux server administration on the run? SSH is a must. A good screen resolution. A physical keyboard won't block the screen with a virtual keyboard. Many physical keyboards omit the numeric keys now, making the typing of numbers rather difficult. Nearly every smartphone has WiFi capability now. Some will do an X display through SSH tunnelling. So, pushing through all the bells and whistles that have nothing to do with effective server administration, what is left?"

jfruhlinger writes "You may have caught PJ's Christmas Day post on Groklaw, expressing her anger and frustration that, after she helped save Novell's Unix patents from SCO's clutches, Novell turned around and sold many of those patents to an open source-unfriendly coalition. She's feeling at a crossroads and wondering what Groklaw should become. Brian Proffitt has a suggestion: a bigger, more community-oriented site."

Modern Perl writes "Larry Wall, the creator of Perl, reflects on Perl's history of hacking its culture, from subverting the reductionist culture of Unix to reinventing the ideas of programming language and culture in Perl 6 and the verbal aikido used to encourage honest detractors to become valuable contributors. Perl turned 23 years old last week, and Perl 6 is available."

An anonymous reader writes "When Novell finally sold itself, part of the deal included the sale of 882 patents to a consortium backed by Microsoft. Thanks to a tip from Florian Mueller, it turns out that Microsoft's partners are Apple, Oracle, and EMC, which raises questions about where these companies are heading and what it means for the rest of the industry."

A beautiful mind writes "WikiLeaks is asking for hosting space on Unix-based servers. The replication is implemented by a rsync+ssh based push that copies static files to a known path, authenticated via the private half of this public key. The complete website is a few GB in size, making it feasible to replicate on a large scale. The mirror list will be published when the number of independent mirrors reaches 50." Note: wikileaks.ch seems to be down for the moment, but eventually the above links may require that instead of 213.251.145.96. See also this WikiLeaks address finder.

ttsiod writes "Back in 2001, I coded HeapCheck, a GPL library for Windows (inspired by ElectricFence) that detected invalid read/write accesses on any heap allocations at runtime — thus greatly helping my debugging sessions. I published it on my site, and got a few users who were kind enough to thank me — a Serbian programmer even sent me $250 as a thank you (I still have his mails). After a few years, Microsoft included very similar technology in the operating system itself, calling it PageHeap. I had more or less forgotten this stuff, since for the last 7 years I've been coding for UNIX/Linux, where valgrind superseded Efence/dmalloc/etc. Imagine my surprise when yesterday, Googling for references to my site, I found out that the technology I implemented, of runtime detection of invalid heap accesses, has been patented in the States, and to add insult to injury, even mentions my site (via a non-working link to an old version of my page) in the patent references! After the necessary 'WTFs' and 'bloody hells' I thought this merits (a) a Slashdotting, and (b) a set of honest questions: what should I do about this? I am not an American citizen, but the 'inventors' of this technology (see their names in the top of the patent) have apparently succeeded in passing this ludicrous patent in the States. If my code doesn't count as prior art, Bruce Perens's Efence (which I clearly state my code was inspired from) is at least 12 years prior! Suggestions/cursing patent trolls most welcome."

angry tapir writes "Novell's copyrights for the Unix operating system will remain under Attachmate's control as part of the companies' pending merger, a Novell spokesman has revealed. The confirmation, which came in a terse message posted to Novell's website, seems to rule out questions of whether Unix assets are part of some 882 patents being sold to a Microsoft-led consortium, CPTN Holdings, as part of the deal."

jfruhlinger writes "Word came down this morning that when Attachmate bought Novell, certain intellectual property rights were sold to a Microsoft-led consortium as part of the deal. Since Unix is the most valuable piece of IP Novell owns, there was a certain amount of panic that suddenly Redmond is in charge of this foundational technology for Linux and a number of other open source projects. But, while MS is being cagey, Brian Proffitt doubts that Unix was part of the IP package that was sold — and believes that Linux would be safe even if it were."
