I have a text file full of tips where I jot down commands that I need to remember.
I've decided to turn them into blog posts instead.

When there's a major update I usually like to simply reinstall the OS. I'll backup my home directory and anything else relevant (perhaps just a few config files in /etc).

So I've installed, got access to the internet, and updated the official packages. Now what?

In Slackware I access slackbuilds from the command line using sbopkg
The program sqg is fantastic - it produces a queue file for the package you want to install.
So you don't have to bother looking up and installing the dependencies, or typing a queue file yourself.

Now I can grab nvidia-kernel and nvidia-driver, my video-card driver.

Another program I download immediately is slackpkg+.

Related to that, I'm using 64-bit and need a multilib system so I'm generally thanking alienbob for that.


That's my basic system. What software do I still need? Don't want to forget...

thunderbird (if they're not already installed)

(Besides Perl, I might use R, octave, ghc, numpy.)

KeepassX (Storing passwords)

audacity (audio recording)
hydrogen (drum machine)


playonlinux (I love starcraft 2, and sadly own a few other windows only games.)

dgen (Sega Genesis)
nestopia (NES)
stella (Atari)
gopanda2 (client for connecting to the pandanet go server)

xboxdrv ( a driver for my old xbox controller, which sometimes works better than the native xpad module... so rmmod xpad && xboxdrv &. You can also run it with --mimic-xpad, or have two controllers with two separate instances using -i 0 and -i 1.)

antimicro (maps keyboard buttons to gamepad buttons, with a nice GUI.)

If there are permissions issues with either of these, you could e.g.
chmod a+r /dev/input/event15
To see specifically which event your controller is bound to
cat /proc/bus/input/devices
(Note that making the event readable by all may cause some software to no longer work.)


On a new install of Slackware 14.2 I had annoying intermittent pauses.
My current solution is to create the file /etc/sysctl.d/dirty_background_bytes.conf containing the line
vm.dirty_background_bytes = 8388608
This increases the size of the buffer so the system does not flush as often.

I have another file there, swappiness.conf containing
vm.swappiness = 10
This was an attempt to lower latency: when RAM is 90% full then swap will be used.
