idiosyncrasy (?) with gnuplot -- or just pilot error?

Posted 09-06-2015 at 11:56 AM by flshope

I just ran into the damnedest idiosyncrasy with gnuplot (http://www.gnuplot.info/). I was doing my routine spending/budget plots when suddenly gnuplot bombed with a cryptic message. I spent all morning figuring out what was wrong. In the end, as usual, it was pilot error ...

I am plotting a data file with up to 12 blocks of data (counted as 0, 1, 2, ..., 11), where each block is separated by a blank record. The command

Code:
plot "datafilename" every :::07::07

Chromium 36 upgrade with SSE2 instructions will not execute on Athlon XP 2400+

Posted 08-31-2014 at 06:36 PM by flshope

I have an 11-year-old computer with an AMD Athlon XP 2400+ (32 bit) processor and ASUSTeK Computer A7V8X motherboard. The machine has Ubuntu 12.04 installed.

A few weeks ago I did a routine software update using the Update Manager. The update was to move to Chromium 36 from 34 (there was no version 35 under Ubuntu). Suddenly, Chromium would no longer run, or even start on this machine, though Chromium 36 is working OK on two other newer Ubuntu machines. When executed from the command...

New Computer Ubunting Away

Posted 04-01-2014 at 08:50 PM by zaivala

A friend of mine sent me a Dell Optiplex 740, complete with box only and no hard drive, only 1 Gb RAM. I happened to have two sticks of RAM in my dead HP which fit the bill, and an old hard drive which never too a liking to Windows XP. Turns out I was running Ubuntu 10.04 on it, in 64-bit flavor. Well, that works for me. I turned the computer on and it ran. That's all I wanted. I upgraded to the latest LTS of Ubuntu.

I have two problems. One is that it boots up with sound muted. I...

First thing to do in an emergency: Nothing!

Posted 11-28-2013 at 11:33 PM by flshope

A few days ago I had a heart-stopping moment on my main linux box running Ubuntu 12.04. I had just deleted two links from my desktop when suddenly I discovered that none of the remaining links on the desktop were working. Worse, clicking on any one of them them produced an error box saying the linked file no longer existed. I actually broke out in a sweat. All of these links are to files on a second internal hard disk where I keep my own data files, as opposed to the files for the OS and the various...

Making a bootable Live-DVD under Ubuntu

Posted 11-19-2013 at 08:49 PM by flshope

A recent article from ExtremeTech at the following link

http://www.extremetech.com/computing...ually-live-for

got me to worrying what I would do if my main boot disk failed. I keep my data files on a second hard disk, which I back up to an external drive on a weekly basis. I don't back up much of the boot disk.

Certainly something I should have is an alternate method of booting the machine. Although I know there are several...
