thatpythonguy writes "Addison-Wesley publishers has released The Python Standard Library By Example, another Python book that strategically fits in between programming cookbooks and library reference manuals. It brings the Python standard library that much closer to Python programmers and helps make them more proficient in their trade." Read below for Ahmed's first Slashdot review.

An anonymous reader writes "Poul-Henning Kamp looks back at some of the bad decisions made in language design, specifically the C/Unix/Posix use of NUL-terminated text strings. 'The choice was really simple: Should the C language represent strings as an address + length tuple or just as the address with a magic character (NUL) marking the end? ... Using an address + length format would cost one more byte of overhead than an address + magic_marker format, and their PDP computer had limited core memory. In other words, this could have been a perfectly typical and rational IT or CS decision, like the many similar decisions we all make every day; but this one had quite atypical economic consequences.'"

badger.foo writes "OpenBSD-current just turned 5.0-beta, providing us a preview of what the upcoming release (slated for November 1st) will look like. Peter Hansteen takes us through the main new features and explains the development process that has consistently turned out high-quality releases on time, every six months for more than a decade."

mdrejhon writes "Geeks who miss the UNIX 'talk' days, have a new modern savior: XMPP.org has published the new XEP-0301 Real-Time Text standard, which allows streaming text that is continuously transmitted as it is typed or otherwise composed. It allows conversational use of text, where people interactively converse with each other."

dtmos writes "Robert Morris, a major contributor to the Unix password and security features while at Bell Labs, has passed at the age of 78. His interesting life was made even more interesting by his son, Robert Tappan Morris, who invented the computer worm."

An anonymous reader writes "With a shiny new version of Presto that's apparently up to 20% faster, cool tweaks to Speed Dial, and a bunch of other features and bug fixes, the crazy Norwegians have just launched the latest version of desktop Opera."

angry tapir writes "Researchers at the PlanetLab global research network have developed a potential replacement for the widely used Unix sudo tool, called Vsys, that will offer administrators far greater control over what end users can and can't access. Vsys is similar to sudo, except it offers finer-grained access to system resources. PlanetLab created Vsys as a way to allow its researchers to access low-level network functionality so they could develop new network technologies — overlay networks, user-level file systems, virtual switches — while their experimental work remained safely isolated from other users."

An anonymous reader writes "With the Linux 2.6 kernel set to begin its 40th development cycle and the Linux kernel nearing its 20th anniversary, Linus Torvalds has expressed interest today in moving away from the Linux 2.6.x kernel version. Instead he's looking to change things up by releasing the next kernel as Linux version 2.8 or 3.0."

scc writes "TermKit is a re-think of the storied Unix terminal, where human views, input and data pipes are separated. Output viewers render any kind of data usefully. It may not be a new idea, but it's certainly a new take on it." I know you are quite comfortable in your shell of old, but this sort of thing sure gets my juices going. The best of both worlds.

Moderator writes "Could Gnome drop support for non-Linux operating systems? That was a recent proposal on the Gnome mailing list, although there were significant objections in response. Quoting: 'It is harmful to pretend that you are writing the OS core to work on any number of different kernels...the time has come for GNOME to embrace Linux a bit more boldly.'"

Zubinix writes "I have a background in doing automation in a Unix/Linux environment using scripting languages such as perl and bash shell, as well as ssh for remote scripting. My next project will be in the Windows environment so what approach and methodology is best for developing, say, the automation required for a test system? I don't want to use things like Cygwin, as I need to integrate with Windows applications such as Exchange and Sharepoint. Is there a list of should and should not dos when it comes to Windows automation?"

An anonymous reader writes "The release of OpenBSD 4.9 has been announced. New highlights included since 4.8: enabled NTFS by default (read-only), the vmt(4) driver by default for VMWare tools, SMP kernels can now boot on machines with up to 64 cores, support for AES-NI instructions found in recent Intel processors, improvements in suspend and resume, OpenSSH 5.8, MySQL 5.1.54, LibreOffice 3.3.0.4, and bug fixes." Also in BSD news, an anonymous reader writes "DragonFly BSD 2.10 has been released! The latest release brings data deduplication (online and at garbage-collection time) to the HAMMER file system. Capping off years of work, the MP lock is no longer the main point of contention in multiprocessor systems. It also brings a new version of the pf packet filter, support for 63 CPUs and 512 GB of RAM and switches the system compiler to gcc 4.4."

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."
