 I was happy the first time I burned the .iso to DVD-RW. However, I saw things I could improve, so I decided to make another .iso and burn that to the same disk.

 I kept getting error messages. I tried 4 different softwares to 'blank' the DVD, some told me it worked, but they all failed.

 Here was the problem:
[Potential Pitfall]: The automounter will detect a formatted DVD and mount it. You can not burn a mounted DVD.
 I found the icon on my desktop, rmc'ed it and chose unmount. Then, I continued w/o failure.

 This is not a glitch, but rather something neat. From a prior post, here is an image of a Laura Croft - like character

 I'm really bummed about this. I use Wine and Firefox 2.0 to access the FOX site so I can watch such shows as Fringe and 24. FOX does not support *nix.

 For the past week, the Move player has flickered the feed making it almost unviewable. I've tried updating Wine, Move and Flash, but it's still flickering and the video is choppy. Audio is OK.

 I got this to work after fussing with it for some time.

speaker-test - command-line speaker test tone generator for ALSA (in Linux)

Code: Select all

$ speaker-test -t sine -f 440 -D plug:front -c2 -l2
 Sends a 440 Hz tone to the front speakers, alternating left then right, loops twice and stops.

 Recording what you hear in lunix? Use the command line and "arecord".

Code: Select all

$ arecord -d 10 -f cd -t wav -v -v  -D front foobar.wav

 See an error in this piece of code?

Code: Select all

REM  *****  BASIC  *****
REM computes the 1st derivative as a function of x and u(x)
Function uprime(x,y)
uprime=(x-y)/sqrt(1+x^2)
End Function

 I'm doing a spreadsheet for another thread. The above is a MACRO I wrote and am trying to use, but all I kept getting was an error message complaining it couldn't find the MACRO. Well, it wasn't the MACRO it couldn't find, it was the sqrt function.

 It turns out, sqrt is a legitimate function to use in OpenOffice.org's spreadsheet, but is non-existent for use in a macro. It took me almost 3 hrs to figure that out. I found the error/solution nowheres on the I'net.

 The BASIC they use for macro programming is Sun's StarOffice BASIC. See StarOffice 7 Office Suite - Basic Programmer's Guide, English, in particular pg. 38.
Mathematical Operators
Mathematical operators can be applied to all numbers types, whereas the +
operator can also be used to link strings.
  • + Addition of numbers and date values, linking of strings
  • - Subtraction of numbers and date values
  • * Multiplication of numbers
  • / Division of numbers
  • \ Division of numbers with a whole number result (rounded)
  • ^ Raising the power of numbers
  • MOD module operation (calculation of the rest of a division)
 So, in my case, I simply had to substitute ^(0.5) for sqrt in my MACRO and everything started to run as planned.

 Fixed. This changed my attitude concerning spreadsheets for serious calculations. Plus, the Open Office Suite is free.

 I just allowed a major kernel upgrade to be performed automatically. Prompted me "to keep menu.lst". The system rebooted properly, afterwards.

 One can control MPlayer not only by mouse, but also by keyboard.

See, read, do

No glitches to report ... I've just managed to get a lot of neat things to work.
