I wanted to mention, for the benefit the community, that I created a patched version of the Tagsistant 0.4 source, which fixes a number of problems with the build system. It is available from my FTP server:

tagsistant-0.4.0-patched.tar.gz

Basically, I wanted to compile tagsistant on my Gentoo system, but the build system was a mess (hardcoded paths, configure script not producing the correct files, and such like). I stripped the build system down to the essential files,...

Low Level Tools & Keeping QT Designer/Assistant from going online w/ remoteControl

[The fix for designer's help menu trying to get online behind your back is at the bottom.]

Before we dig back into low level code, let's talk about low level tools in general for a sec.

And what I mean by "low level" in this context is where things are not done so automatically for us. Where you actually can get your hands a little dirty -- "hands on",...

Radar maps gone retro.

Posted 04-24-2012 at 04:26 PM by peonuser

Once in a while I sort of come up with a neat idea. At least it is to me. Just because you have an old system, does not mean you can not teach it new tricks. Done a lot of page scraping to get weather details, but it would be nice to use radar screens from the command line. So details in this case are not so necessary. The overall view of the weather to see what kinds of weather fronts are approching is.

Here we go. We need to collect some historical data (i.e. radar screens). You...

Removing files with find, and LVM snapshots

Posted 04-24-2012 at 11:21 AM by sag47

Tags find, lvm, snapshot

Take an LVM snapshot using a loopback device
Create the snapshot
Take a look at the devices in your volume group. First there needs to be sufficient space in the volume group for a snapshot to occur. Check this by typing: vgdisplay and checking for Free PE / Size

Code:

vgdisplay -v

Create a loopback device to use for the snapshot. My volume group is named vg_echo360. I want my snapshot to be 9.9GB in size so I'm creating a loopback device which is 10GB in size....

I could have sworn that early versions of QT4 couldn't do this. It still can't do some things the old QT3 could do "progress" is like that, but it looks like this one might work if you have a somewhat recent version of QT4 (and designer or creator and kde).

Here's a bit of Computer Mad Science that you might find interesting. Or at least amusing.
