Slashback is back from a Thanksgiving hiatus with a bigger-than-usual collection of updates, corrections and followups to previous Slashdot stories, including pretty maps of the Internet, spammers' OS choices, stupidity in the wild, and more. Read on for the details.

Ed Almos asks: "Like many Slashdot Readers, I run a small network at home with a server and a number of desktops. The server holds all our files as NFS shares and doubles as a desktop machine should the need arise. Problems however occur if the server is shut down whilst there are NFS shares in use, the minimum disruption is a crashed desktop and a couple of times I have had to deal with corrupted files. Does anyone know of a way to prevent shutdown of a machine if someone else has drives mounted to its NFS shares ? I have already explored use of the /etc/shutdown.allow file but all this does is determine who can kill the machine. The minimal solution would be something similar to a Microsoft Windows system, where a request to shutdown brings up a warning window that there are users connected to the system, but I am not sure how to achieve this on a Linux system. Ideally I would like to prevent shutdown of a system with active NFS shares altogether, or at least until the user has unmounted and logged off the network."

Lucky writes "Bruce Peren's idea for UserLinux was much discussed on Slashdot some weeks ago; however, there was no formal proposal. Linuxworld is running an analysis of the proposal and links to the first draft."

thx2001r writes "According to News.com, Matthew Szulik (perhaps driven by recent slashdot questions in this regard) of Red Hat has set educational pricing for Red Hat Enterprise Linux Workstation ($25 per year for students) and (RHEL AS) server ($50 per year for the schools). Here are the details of the versions available at educational discounts." And for business users wary of Red Hat's high-priced Enterprise version (and happy using an older version), iroberts writes "Beginning January 1, 2004, Progeny will offer software updates for users of Red Hat(R) Linux(R) 7.2 and 7.3. Pricing is $5 per machine per month; or a flat rate of $2,500 per month for unlimited machines. The Fedora Legacy Project is discussing how this will impact their work."

costela writes "LWN points out that the Gentoo project fired out an alert about one compromised rsync server." From the message itself: "However, the compromised system had both an IDS and a file integrity checker installed and we have a very detailed forensic trail of what happened once the box was breached, so we are reasonably confident that the portage tree stored on that box was unaffected." Update: 12/03 22:54 GMT by T : One more damage report: gibson writes "The Free Software Foundation recently discovered that its software host site was compromised a month ago. The compromise appears to be the same as the recent attacks on the Debian servers. The site is shut down until Friday while they install replacement hardware and verify the authenticity of the hosted source code."

ilbrec writes "Looks like NTT DoCoMo will be using Linux on their 3G phones next year. This actually was reported yesterday in Japan (here), but I could not find any article in English until now. While it's not clear who will be making the Linux phone for them, I would certainly be interested in seeing them once they are out. No word on this anywhere at DoCoMo's website at all, however." Reader paku adds links to similar coverage in Forbes and in Japan Today.

nileshch writes "The ongoing community-driven Linux Bangalore 2003 is upto a record of sorts. There are, hold your breath, 96 scheduled talks. That's about 96 hours of open-source talk in three days! The first day with 30 talks is already over with star speakers like Nat Friedman, Miguel De Icaza and Sirtaj Singh Kang enthralling the audience with their refreshing perspectives on Linux and Open Source. Rasmus Lerdorf and Jeremy Zawodny of Yahoo! Inc, amongst others, are also scheduled to talk at the event."

caseih writes "A very neat hack uses the real ntfs.sys driver (obtained from your own windows XP partition and used via a wine-like layer (borrowed from ReactOS) to mount an ntfs partion with full read/write access. While not an ideal solution and certainly not free as in speech, this is an ideal stop-gap measure for many people trying out linux. I think that we'll probably see this in Knoppix pretty soon."

Zelligar writes "You may want to check into the brewing trademark issues between SSC/linuxgazette.com and the linuxgazette.net people - linuxgazette is a volunteer gazette, hosted by SSC for a while, and now SSC is taking it over - and threatening trademark litigation to boot! Here is one story and another on the subject."

DarkSarin asks: "I have a rather serious problem: I managed to accidentally delete some files (rather important ones at that!) while trying to back them up to cd (I was using a GUI burning software that will remain nameless for now). How do you recover accidentally deleted files in Reiserfs? This thread (started by me) indicates that you can't recover them. Note that I had found a way to rebuild the tree, but that didn't work. It seems odd to me that you wouldn't be able to recover accidental deletions, but that really does seem to be the case. Help? Please?"

penguinrenegade writes "Element Computer has come out with the first sub-$1000 Tablet, and it doesn't come with Windows. It's not running a stripped OS like Windows CE, but a full-fledged copy of Lycoris Desktop/LX. This company seems to really have it in for Microsoft, with a 'No Windows' policy. Good to see someone finally standing up against paying the Microsoft tax. Maybe now we'll start seeing Linux only OEMs and resellers." Also on the tablet computer front, SeanAhern points out Cringely's latest Robert X. Cringely column, in which Cringley makes the case that Apple is readying a tablet computer for market, and "suggests that 'until next year, the parts won't have been there to make tablet PCs successful. What's missing has been the killer app, and what kept a killer app from appearing was a lack of hardware support, which I believe will be over soon,'" writing "He's got some interesting ideas about where Jobs might go with his Digital Hub idea." (This is an Antaur-based machine, not the Toshiba tablet mentioned in October.)

mbanck writes "The cause of the recent Debian Project server compromise has been published by the Debian security team: 'Forensics revealed a burneye encrypted exploit. Robert van der Meulen managed to decrypt the binary which revealed a kernel exploit. Study of the exploit by the RedHat and SuSE kernel and security teams quickly revealed that the exploit used an integer overflow in the brk system call. Using this bug it is possible for a userland program to trick the kernel into giving access to the full kernel address space'. This issue has been fixed in 2.4.23. Thus, the Linux kernel compromise was not Debian specific."

joestar writes "MandrakeSoft just announced the release of the MandrakeMove release candidate, a special desktop version of the Mandrake Linux distribution that boots live from the CD and uses a USB key (included in the retail version) to automatically store personal data. It looks a bit like Knoppix, but comes with more features, such as the capability to eject the MandrakeMove CD-ROM during its use, in order to read audio or video files from another CD! The download release candidate is available here."

An anonymous reader writes "LinuxDevices reports that Wind River, the world's #1 embedded software company, moved two steps closer to Linux today, with a pair of announcements that it has joined two key organizations. Wind River has joined the Open Source Development Labs (OSDL) and says it plans to contribute to the OSDL's Carrier Grade Linux (CGL) working group. Wind River also announced that it has joined the Eclipse Consortium, an industry group devoted to an open cross-vendor platform for development tools integration, and that it is committed to the Eclipse platform 'to enable global enterprises to standardize embedded development on a single, open standards-based integrated development environment (IDE).' This follows an October Linux tools announcement which it called 'just the first step.'" We had also covered the initial announcement.

An anonymous reader writes "In an interview with Red Hat Asia Pacific boss Gus Roberston, he tells ZDNet why he believes Unix will be dead since in future, there will only be two operating systems left (for corporations). "We don't see ourselves competing against Microsoft. We are taking market share away from Unix," he said. However, IDC counters Robertson's claim saying Unix market share has actually been increasing in that part of the world."

Ridgelift writes "This article indicates Red Hat Linux is about to receive certification under the Common Criteria (CC) Scheme worldwide. This has been a long road for Red Hat, and 'once successfully certified in the UK, Red Hat products will be recognised as certified and approved by information security agencies from all 19 countries participating in the Common Criteria program.' This means Red Hat will sit alongside Sun Solaris, HP-UX and IBM's AIX."

AEnertia writes "Novell have been quick in moving ahead with their recent aquisition of SuSE. I was browsing their site when I found this page describing their new certification (CLE) under their certifications programs. Looks like they are positioning their well respected certification program for their newest asset."

Bob Plankers writes "By now we've all heard about IBM's Blue Gene/L, LLNL's remarkable new supercomputer which is intended to be the fastest supercomputer on Earth when done (360 TeraFLOPS). IBM has released some new photos of the prototype, and renditions of the final cluster. Note that the racks are angled in order to permit hot air to escape vertically and reduce the need for powered cooling. The machine uses custom CPUs with dual PowerPC 440 processing cores, four FPUs (two per core), five network controllers, 4 MB of DRAM, and a memory controller onboard. The prototype has 512 CPUs running at 700 MHz, and when finished the entire machine will have 65536 dual-core CPUs running at 1 GHz or more. Stephen Shankland's ZDnet article also mentions that the system runs Linux, but not on everything: 'Linux actually resides on only a comparatively small number of processors; the bulk of the chips run a stripped-down operating system that lets it carry out the instructions of the Linux nodes.'"

swillden writes "Iain Barker and some other Linux Kernel Mailing List readers have discovered that several manufacturers of DVD players based on the Sigma Designs EM8500 chipset are distributing Linux, both in the devices and as binary-only firmware upgrades, but not providing source. Apparently, Sigma Designs provides its customers with a copy of the kernel as part of a chipset SDK, and those customers are making and selling devices without complying with the terms of the GPL. It's not clear if this is because Sigma didn't tell its customers about the GPL and their obligations, or if they're all ignoring it on their own. Maybe they've all bought licenses from SCO and therefore don't have to comply with the GPL? The LKML post contains a list of some of the infringers."

MikeCapone writes "As if we didn't already have enough articles about Linux kernel releases, Marcelo Tosatti has released the final 2.4.23 Linux kernel. Check out the changelog at Kerneltrap."
