Reminder: WLUG Meeting Next Wed (3/9) Topic: Virtualization Technologies
by Tim Keller March 2, 2011

March 2, 2011

Hey Everybody, This is a reminder that next Wednesday I'm going to be giving a talk about virtualization technologies. I plan to do some white boarding, slides and a demo of different virtualization products currently on the market (both closed and open source). If anybody has specific questions or specific things they'd like to me to cover let me know and I'll update/expand my slides and notes to cover it. Thanks, Tim. -- I am leery of the allegiances of any politician who refers to their constituents as "consumers".

Remembering KO
by Ken Jones Feb. 13, 2011

Feb. 13, 2011

I shall reveal my age. I was a working AN/FSQ7 programmer in Group 67 at Lincoln Labs when KO took off on his crazy venture to that mill in Maynard. I did not know Ken at the time as he was in Group 64 if my memory serves me correctly. DEC's first products were 'logic boards'. Those were the days of 'wire wrap' breadboarding. Ken's cards built with itty bitty new fangled transistor things slipped securely into a standard wire wrap board. I do not remember any specific cards, but I know they consisted of multiple individual NAND and NOR gates and probably a couple of FLIP FLOPs. >From that came the PDP-1 which I never saw. My memory focuses on the PDP-8 which was popular - so to speak. To put this in perspective the US had just deployed the SAGE air defense computers all around the country to detect and intercept Russian atomic bomb carrying jet airplanes. The SAGE computers used water cooled vacuum tube technology. I suggest, if you can find a library (remember them?), that is open check out "DEC is Dead, Long LIve DEC" The Lasting Legacy of Digital Equipment Corporation by Edgar Schein. (Is it available on NOOK?). My read of that book was that DEC was fine and healthy so long as it's engineers were producing products the customers did not know they needed, ie DEC was never consumer driven. (This is part of why KO was so beloved.) I was a TCP/IP aware person when I went to work for DEC in 1985. Inside those DEC walls DECnet was not only everything, it was the only thing. Ken Jones

A nice article from Jon Hall is on top of the blog http://www.linuxpromagazine.com/Online/Blogs/Paw-Prints-Writings-of-the-mad… along with many other replies about PDP-* systems, VMS, etc. My first HIGHtech job (1985) was hanging tapes and keeping dumb terminals alive and connected to four VAX 750/780's running (not VMS but) BSD4 unix (before NFS, before NIS) for a robotics shop in Billerica called Automatix. csh% a.out hello, world !

Computer Recycling - Wlug Digest, Vol 88, Issue 6
by Steven Greenberg Feb. 5, 2011

Feb. 5, 2011

Just before moving from the Portland, Oregon area back to Massachusetts, I did have the proverbial closet of old computer equipment. Portland had a place that you could bring this equipment to for recycling. They charged a small fee to take the equipment off your hands with the commitment that they would refurbish it or otherwise recycle it. Of course Portland had such a strong green ethos that a business like this could flourish there. I figured I did my part for the environment and saved the cost of moving the dead weight across country and storing it in a closet here. /Steve On 2/5/2011 12:00 PM, wlug-request(a)mail.wlug.org wrote: > Send Wlug mailing list submissions to > wlug(a)mail.wlug.org > > To subscribe or unsubscribe via the World Wide Web, visit > http://mail.wlug.org/mailman/listinfo/wlug > or, via email, send a message with subject or body 'help' to > wlug-request(a)mail.wlug.org > > You can reach the person managing the list at > wlug-owner(a)mail.wlug.org > > When replying, please edit your Subject line so it is more specific > than "Re: Contents of Wlug digest..." > > > > Today's Topics: > > 1.

If you can come up with a special niche market, like a car/boat/RV computer or a DVR/HDTV computer for a particular market that has some kind of Television access problem, then you may find a way to profit. It is very hard to go up against the low-end and sale machines at the stores. If you are a great seller, you may be able to talk your way into some customers. In Florida, there are a couple of small companies doing neighborhood wifi internet access for a great price, but even they depend more on the internet charges and the computer service calls than on system sales. Service and training seems like the most profitable part of the picture to me. Still, I hope you find a way to do this. I hope I don't sound too negative. I'm just a regular guy without any strict training or a business degree, so I'm certainly not the last word on the subject. DaveC -- David P. Connell "Watch where you're going; remember where you've been." Hey, Sorry for not chiming in sooner. I remember while working on my MBA trying to work out how to run a small for profit local PC and support business aimed at home consumers and an occasional small business. The short answer at the time was the advent of the "shiny new $450 PC" made computers toaster-ish (breaks - put in basement/closet - buy another). In the ensuing decade plus since I have confirmed two things IMHO: 1) The price of entry level PCs are going even lower. I haven't looked but I bet there are refurbs out there for $200-ish. This fact makes it harder for a consumer to pay even $25 for someone to work on their (likely 2 to 6 years old on average) PC whether in a shop or in the home. The business person's reasoning is "good money after bad". Not sure why home consumers do this, but they do. 2) Most non-IT geeks have a small closet/basement pile of PCs somewhere in their house if they haven't moved within the decade. Moving of course drives people into momentary sanity with "Why am I keeping / saving / moving all this useless junk?" Geeks of course re-use them as personal firewalls / coffee warmers / Myth boxes / ways to communicate with aliens / ... App won't install... Printer cable won't connect... Adware and viruses got you slugging along... Bad device driver killing your uptime... Your 18 long hair cats packing the case with a fur effigy with expected heat & reboot issues... Consumers answer to all is: "Buy a new PC!" Ask around to non-geek friends/co-workers. You will be amazed. A family friend is on their 4th brand new computer in 3 years. I assure you the scope of work has not changed (web browsing, e-mail, facebook, etc). I am now wondering how do you get these closet PCs for cheap/free then image them to get them useful again. Obvious start is to get referrals from moving companies that quote household moves, then call offering to remove their unused PC's for free. Somewhere there must be a support group for home consumers who have their own Dell rep on speed dial. I am not bashing Dell here, merely using their name in the examples to make a point, Joel

Kernel Crash dump
by Andy Stewart Feb. 3, 2011

Feb. 3, 2011

HI guys, I finally got some type of crash dump from my system. I have tried Ubuntu variations of the 2.6.35, 2.6.36, and 2.6.37 kernels, all of which have crashed on me. Finally, 2.6.37 gave me a trace on the console screen. I had to copy it down by hand, so don't take it too literally. Here is the data. I intentionally left out all of the hex addresses in the call trace. It seems pretty obvious to me that something is amiss in the hardware. I wonder if my heat syncs are full of dust. That will be the first thing I check. Any helpful advice would be most appreciated. Thanks!

Well, I cleaned out a bunch of dust...maybe a heat problem caused some weirdness. I'm also running memtester on the live system...so far, so good. The machine is about 5 yrs old - maybe this is my excuse to build myself another one. The crash is weird, sometimes it crashes within a couple of minutes of booting the system, and other times, it takes a week. I still claim that it started happening when I upgraded from SuSE 10.1 to Kubuntu 10.10, but I did open the case and install a new SATA hard drive at that time as well. This machine was an absolute rock when running SuSE 10.1. We'll see what happens...thanks, everybody, for the helpful suggestions.

Unstable Linux in recent releases
by Andy Stewart Jan. 19, 2011

Jan. 19, 2011

HI gang, I've read an awful lot of posts recently describing freezing or hanging systems in very recent versions of several Linux distributions. Unfortunately, I got one of them - Kubuntu 10.10 (I *knew* I shouldn't have upgraded from the very stable SuSE 10.1, except that it was quite old). My system arbitrarily hangs/freezes at unpredictable intervals. Sometimes I can make it happen 2 minutes after a reboot, and other times it takes a few days, but invariably, it does occur. I can usually induce it by doing something semi-stressful to the video, like watching something via mplayer, but it doesn't always occur. The postings I've seen appear to describe a wide variety of hardware and software configurations, and nobody can seem to find any error data in any log file. What I can't find is the solution, and I've googled extensively. Has anybody found anything online that talks about some very recently discovered bug and its fix that would cure the problem? Thanks!

Unstable Linux in recent releases
by Kevin Paetzold Jan. 17, 2011

Jan. 17, 2011

In case no one made the connection between my previous messagesubject and this thread..... They are the same. I believe that the fix i pointed out is the cause of these "unstable" linux's. Certainly the fix worked for me. When I first booted with one of the fixed kernels it ran for a wk (before i rebooted). Previously my machine was hanging at least once per day and at some points every hour or so. And in answer to previous question, the machine was hung such that it was not possible to ssh into it or make it respond in any way. Indeed after using the power switch to turn off the machine I still had to pull the AC plug to get it to be able to reboot.

hanging kernels #2
by kevin.paetzold Jan. 17, 2011

Jan. 17, 2011

I meant to say that I am now running vmlinuz-2.6.35.10-77.fc14.i686 from fedora 14 koji. Both the above kernel and vmlinuz-2.6.35.10-75.bz667459.fc14.i686 seem to resolve the issue. http://kojipkgs.fedoraproject.org/packages/kernel/2.6.35.10/77.fc14/ In fedora this problem seemed to show up with the 10-72 kernel and was perhaps even worse with 10-74 kernel.

hanging linux
by kevin.paetzold Jan. 17, 2011

Jan. 17, 2011

I recently saw comments on this list about kernels that hang. Indeed that was/is true for fedora 14. The symptoms I saw were essentially a frozen screen with no mouse pointer etc... In my case I would actually have to power cycle (actually pulling the ac plug) my dell pc to reboot it. In my case I believe that the bug (in fedora land) was bz667459. see https://bugzilla.redhat.com/show_bug.cgi?id=667459 I was a comments in this bug pointed me at a bug fix kernel "vmlinuz-2.6.35.10-75.bz667459.fc14.i686". This kernel resolved the problem. By the way, I have now upgraded (on friday) to vmlinuz-2.6.35.10-75.bz667459.fc14.i686 from koji which has also been stable.

Re: [Wlug] Any idea where to find a job?

Any it position will do, as for travel marlboro, framingham, etc are all fine by me, boston would be a bit far. My retail experience consists of: logistics, electronics sales, and hourly management. Prior to that I used to sell, repair and build computers. And would troubleshoot and set up networks. As well as contract programming. I'm a jack of all trades when it comes to computers really. Id actually like to avoid any linux positions as I'm not really sure how to rate my knowledge. I can install a working gentoo system without the handbook, if that gives any hints.

Andy, I'm sorry, I got the emails mixed up. It could be a driver issue, but I only suspect that due to the freezing under heavy video load. Could I also suggest trying a different video card to eliminate hardware issues? The video card may have started to fail as you switched distros, unlikely but possible?

Hi Jason, My graphics chip is the ATI Radeon RV280 (Radeon 9200 PRO), and it is running the Free Software driver. There is nothing proprietary in use for the video. I don't generally like to use the proprietary drivers, but perhaps I could try it to see if it makes any difference.

Dec Meeting announcement / linux-raid problem
by Eric Martin Jan. 16, 2011

Jan. 16, 2011

I just realized that I haven't received anything from WLUG in over a month, including the announcement for this past meeting. Did anybody else have this problem or is it just me? Now, the main reason for my email. My mythbox / home file server runs linux soft-raid in RAID5 with 3 500GB disks. One disk went bad a while ago and the array never rebuilt itself. The other day, the second disk went bad. Am I hosed? I've been googling for 'rebuild bad linux software raid' but all I get is the rebuild command. Also, I don't see any tools that will move bad data to another spot on the disk. This is my first time using software raid so I'm in a bit over my head. thanks! -- Eric Martin

Old man and LINUX
by Ken Jones Jan. 14, 2011

Jan. 14, 2011

Folks, I have always wondered at my ability to keep the myriad of LINUX instructions in my head. What would I do if I were to start losing them? Is there a tool to search for recall? Is there any way to go backwards in LINUX command land? If I were to remember that there is a command that will print on standard output the contents of a file in txt characters, but could not for the life of me remember 'more'. Where would I go for help (other than sending a email to this list serve)? All the command dictionaries I have are alphabetic. Ken Jones (the elder)

Re: [Wlug] Old man and LINUX

Unix/Linux command names were exactly what drove me crazy when I first had to use Unix. I wanted to list something on the terminal, or maybe type it. Who would have thought to "cat" it or "more" it. And then we have the aptly named utilities like "awk". I was so proud when it finally dawned on me what the letters "a" "w" and "k" stood for. So I eventually did learn all the commands, but I never thought about the problem of forgetting them until this digest entry. I had the same reaction to emacs in the beginning. Doing apropos in emacs is not helpful when the concept you associate with the task is nothing like the way it is named or described in Emacs. I have learned to write down in a diary on my computer every time I finally find the hard to find command in either Emacs or unix/linux. The next time I want to do the same thing and I have forgotten what the command is, and I finally give up trying to find it in emacs, I can search my diary. Chances are the diary entry will be associated with the word I mentally associate with the task. /Steve -- Steven Greenberg Email: steve(a)ssgreenberg.name 251 Holland Rd.

All Ken> the command dictionaries I have are alphabetic. man -k something where something is vaguely related to your needs. In this case, I just did 'man -k text' and the last things that popped up were 'zmore'. Plus a bunch of other system calls and library calls about text handling. Maybe pickup one of the linux for beginners books that O'Reilly puts out? Unix in a Nutshell, etc. That should help you find commands. Also, *any* text editor will let you read a text file, even if you don't want to edit it.

If you want to see more than one command at a time, open .bash_history in your home with a text editor, or, while you're still remembering it, do 'more .bash_history'. If you remember the command, but you can't recall what options you used with it, 'grep some-command .bash_history' can help. You can set the system to hold more commands, if you want. In debian, the default is to hold the last 500 commands. I don't recall what it is in other distros. Spiral-bound notebook is good, too. A couple of pages of your favorite commands and just about anything else will still be readable if the system crashes.
