nojayuk asks: " Over the decades I've re-skilled myself several times, from mainframe FORTRAN through minicomputer PASCAL to microcomputer C. In between I've done microcontroller development and programming in Assembler, robotics, graphics design and 3-D animation for TV, PC build and repair, Website design etc. Currently I'm looking for work and I'm wondering what new skills do I need to stay in the computing biz. What OSes do I need to know, what technologies do I have to have under my belt for the employers to come hunting for me instead of me passing my obsolete CV around and being told to get lost? I'm looking for advice, not just for next week but for a few years down the line. What can I do to acquire these essential new skills?"

chipperdog asks: "I am looking for an activly maintained console based word processor, similar to what one could find with Appleworks, from the Apple // era (Prodos 8 version, pre-//gs), or even one comparable to DOS versions of WP and Microsoft Word. An open-source one that compiles and runs in Linux would be best, although it would be nice to find one that could run on a 486DX2 50MHz with 8MB. A Google and Freshmeat search only turned up editors that seem to lack some of the necessary word processing features I am seeking. Although I mostly use VI (and *TEX when necessary), some no-so-geeky end users need the quasi-WSIWYG interface."

prmths writes "mplayer now plays sorenson V3! This is the last major format that was unplayable under linux and it has now been conquered! They also added the 2xsai algorithm for video scaling. This will let you increase the resolution of non-photo-like videos (anime/cartoons) by 2 times -- it's not a blurring algorithm -- 2xsai actually guesses edges and fills in the pixels."

smelroy asks: "My software company recently released a Linux port of our business instant messaging product, but we are not sure of the best way to sell it, since to many people selling Linux software is an oxymoron. Users on each end of the computer knowledge spectrum associate any and everything Linux with free. Even when we tried to get people to beta test it for us they said, 'It runs on Linux so why isn't it free?' Another comment from a reporter in response to our telling him of our Linux release was 'So it is open source then right?' So my question to the Slashdot community is when is Linux going to be prevalent enough on the desktop that people will pay for applications and not always assume they are free? Better yet, where are the people who feel that way now?"

mikosullivan asks: "I'm a programmer for the Roanoke Rescue Mission in Roanoke, VA. The mission provides meals, shelter, and other help to the homeless. We're looking at upgrading the mission's information systems to a Linux-based network, from server to desktop. One of the major wrinkles in our plans is finding a good accounting system for Linux. My manager strongly feels (and I sympathize) that they should stick to accounting software that is already used by established accounting firms. There are certainly a plethora of Linux and open source accounting packages out there, but she wants to stay away from the bleeding edge, at least for accounting. She wants a tried-and-true, established, conservative choice for accounting software. What accounting software for Linux is most accepted and established in the marble and wood-paneled world of conservative bean counters? It doesn't have to be open source, but cost is a major issue, and open source is, of course, preferred."

brainchill asks: "I've got about 10,000 users split between a couple of quad 550 xeon machines. The machines have 2GB of ram. The problem is that the UW POP3 server takes a huge hit in both cpu and memory utilization when a 40+MB mail spool is requested via POP3. Sometimes it's bad enough to drag the monster boxes to their knees. What other POP3 daemons do you guys have experience with and how do they perform with large mailboxes"

gwhiteacre asks: "I have been asked to assist a small TelCo that has recently begun acting as an ISP for it's customers having DSL and Cable connections. They currently use the DHCP config file as their authentication database. They add/del/mod the mac address in the config file for each change, stop and start the dhcpd, and are rapidly discovering that this is not a scalable or sustainable approach. I have spent several days researching alternate forms of DSL/cable authentication and am not finding much. My current 'best thoughts' are to put a wrapper around DHCP to intercept the request, check a database, and then call dhcpd. Has anyone dealt with this or a similar issue, and can point me in a good or alternate direction."

Miscellaneous stories about Linux usage today: the Australian government has allowed (but not required) its agencies to switch to Linux. China is apparently going to go all-Linux for the 2008 Olympic games in Beijing. And business2.com has a story about chain of snowboarding shops (and other businesses) deploying Linux cash registers and desktops.

Unknown Relic asks: "Because of the number of virii which are propagated through email, and the tendancy for some users to open executable attachments no matter what they are told, we have decided to seek out a server side solution. We are currently running Linux with qmail on the server side, and while a we have found a couple of products which may fit the bill, I wanted to hear about the experiences and recommendations of slashdotters on this subject. Do you or your company make use of a server side virus scanning engine, Open Source or otherwise, and if so what are your impressions?"

Demiurg asks: "My company has recently decided to support Linux for it's embedded networking products which means that I'm starting to write Linux device drivers for our hardware. The company was very concerned about GPL issues and consulted a lawyer - who advised us to go for a user-space driver, saying that this is the only safe way to avoid GPL issues. I tried to give them a few examples of companies distributing binary only drivers (NVIDIA and Rational) but was told that these companies do not distribute binary only drivers - they only allow you to download them from a web site (which is not an option for an embedded product). What does Slashdot have to say about the issue? Is writing a user-mode (and hence not very efficient) driver the only way for a company to protect it's intellectual property? Please refrain from giving answers like 'all code should be GPL' - although I personally may agree, such answers will not help me convince management to make the change." Are there any lawyers (or readers with the right legal knowledge) out there that can confirm or contradict this recommendation?

grylnsmn writes "The Washington Post today has a front page article talking about how the Extremadura region in Spain is converting all government offices, businesses, and home from Windows to Linux. The article talks of their problems last spring and how the community banded together to solve them. "But the glitches are more an annoyance, [Ana Acevedo, who heads one of the government's document-processing units] said, than a hassle. 'It's mostly very tiny things,' she said." Overall, this is an important testbed for localities all over the world who are looking at making the switch. Overall, a very good and balanced article." Update: 11/03 20:37 GMT by T : Headline misspelled "Extremadura" as "Extramadura" -- fixed now.

heretic108 writes "From first boot to full desktop in 20 minutes! Knoppix has shot into the spotlight as a GNU/Linux distro suitable for demonstrating quality Open Source Software, standing out for its ability to self-configure itself into a vast range of hardware, and to run entirely off a CD boot without interfering with any existing system setup. That, plus its fat catalogue of pre-installed desktop software. But OSS enthusiast David McNab has poked a bit deeper, and found that Knoppix can install itself to disk, resulting in a completely configured GNU/Linux desktop system, ready to use, in 20 minutes, hassle free. CD no longer needed! Best of both worlds - use as a GNU/Linux demo disk, and if the user likes it, it's a snap to install permanently. I can't think of any distro that comes close to this, for ease and speed of setup. I found McNab's short Knoppix Installation Howto which gives a very brief and easy guide. With this rapid setup ability, Debian-based Knoppix makes a great contribution to the catalogue."

GonzoJohn writes "Linux Orbit explains how: "A very common question that comes up when trying Debian GNU/Linux is how the heck do you get Advanced Linux Sound Architecture (a.k.a. ALSA) sound modules set up properly? In this HOWTO we'll show you how to compile and install the ALSA kernel modules, and then setup things using the ALSA Debian script so that modules are automatically loaded and unloaded, and your mixer levels are saved and restored on boot up. Here are some things you'll need to have before you start this HOWTO""

LeftOfCentre writes "The Register reports that the European Commision, the executive arm of the 380 million population European Union, has decided to spend 250,000 Euros on studying how government computers in EU states could be migrated to Linux and open source."

yppasswd asks: "I'm looking for a (cheap) solution for filesystem sharing between two linux servers and, since the target is just redundancy, I've come to the following idea: two SCSI controllers, one per machine, with different IDs (say 7 and 6) sharing the same disk. Only one of them would mount the disk, the other is just ready in case of failure. I've googled this around, and I've found many different opinions (Yes, no, perhaps, don't do it or it'll explode,...) but nobody saying 'Ok, I've tried this and here is what happened...'. Suggestions are welcome, but keep in mind that many other solutions (Fiber Channel, SSA, NFS mounts, various network filesystems) were already rejected because they were either too expensive, unreliable or not supported under Linux."
