Fallout

matt | February 28, 2010

I finally finished playing through the original fallout (bought for $6 from gog.com). Totally worth it. Very, very good game.
I should note that it runs just fine under wine (tested: 1.1.31 aka the one which ships with Ubuntu 9.10).
Oh, and for the curious, the maintainers of the WineHQ AppDB drop “old” versions of Wine, without [...]

lxc basic howto

matt | February 20, 2010

largely from:
http://lxc.sourceforge.net/lxc.html
https://help.ubuntu.com/community/OpenVZ
http://www.ibm.com/developerworks/linux/library/l-lxc-containers/
With additional notes from:
http://www.stgraber.org/2009/11/06/lxc-containers-or-extremely-fast-virtualization
http://linux-vserver.org/Upstart_issues
http://lxc.teegra.net/
1.) Note that you likely want to create a separate partition for machines and put the machines there.
2.) apt-get install lxc debootstrap
(Note – this is pretty inefficient in terms of space. The lxc setup does allow for read-only mounts of things. So, it can have its own /etc and html docs [...]

Windows task manager vs ps

matt | February 2, 2010

So, I was fiddling with java stuff at work the other day, and was struck by just how useless windows task manager is.
When running several:
java -jar something.jar
GNU ps actually shows which is which, because it includes the name of the jar file.
Windows just shows javaw.exe for all of them, so you don’t know what you’re [...]

lxc is awesomes

Win.
(More to come. I’ll also be updating the community docs once I have all the kinks ironed out.)

Is network mounted /usr/local obsolete?

matt | January 30, 2010

It used to be that, back in the day, /usr/local was an NFS mount on a central server, with appropriate trickery so that each machine got the correct binaries for its architecture. This allowed for reduced storage requirements, plus easy upgrades of new applications. I question if this is an idea which has basically become [...]

Computer security

matt | August 31, 2009

The more one reads, listens, and researches computer security, the more it makes one want to sit on ones front porch and drink beer, because there’s nothing else you can do.
It isn’t helped by the fact that users are completely retarded and do things like stick MRI machines on the intertubes.

SCADA

matt | August 26, 2009

Don’t connect control systems to the intertubes!!!
Since we make such systems at work, this was the subject of some lively discussion at work today, especially since we make a unit which connects home via a cellular modem.
This stuff can be really, really scary if not done carefully.
What is even more scary are old, insecure protocols, [...]

… and there it is

matt | August 19, 2009

I once heard (likely on Floss Weekly) someone say that if you want an application, think about it, wait 24 hours, then go look for it, someone will have written it, and it will be open source.

Now all I need is a reloading data application. If I end up having free time to start reloading [...]

More random bits

Student Arrested for Modifying Consoles – This guy didn’t copy any games (at least, the article doesn’t say he did), thus, he didn’t commit any copyright infringement. This can be used for playing pirated games, but it can also be used for playing homebrew games, or running “unauthorized software” (like Linux). In case it is [...]

Facebook

matt | August 4, 2009

So, I’m now on facebook. Folks are welcome to friend me, if you like.
I can’t say that I really get it. The various communication entries are too short to be able to engage in any type of meaningful discourse, and I can’t say that the various media facilities are used much.
That said, I think I [...]
