Stash your cache

Filed under
HowTos

Here’s the deal: I reinstall once, sometimes twice or even three times a week. Why? Well, that’s beside the point. Sometimes I break something, but sometimes I just feel like it. Never mind that. What I want to suggest is that, if you’re like me, you can save yourself a little bandwidth and a lot of time downloading if you take the time to copy your apt cache before you erase your drive.

Filed under
HowTos

Earlier this year, I was asked to find a bootable CD that would allow PCs in a special purpose lab, many of which had bad hard drives, to access our Citrix environment. Basically, we wanted to turn these PCs into thin clients to extend their life. I had been experimenting with Knoppix and decided it was time to try customizing my own Knoppix CD for use in the lab.

How can I change the default size of an inode when I create an ext2/ext3 filesystem?

Filed under
HowTos

It is possible to define a non-standard sized inode by using the mke2fs tool with an undocumented option, -I. The size of the inode has to be a power of two and between the size of EXT2_GOOD_OLD_INODE_SIZE (128 bytes) and size of blocks in bytes. One reason for doing this could be that user is going to use extended attributes.

Removing files from /tmp at shut down

Filed under
HowTos

Your /tmp directory in Linux is a handy place for your OS to stick files that it may need at the moment but won’t need down the road. While this is great for the OS (and you if you want to use it yourself feel free) it can cause a bit of clutter as files start building up.

Put your OpenSSH server in SSHjail

Filed under
HowTos

Jailing is a mechanism to virtually change a system's root directory. By employing this method, administrators can isolate services so that they cannot access the real filesystem structure. You should run unsecured and sensitive network services in a chroot jail, because if a hacker can break into a vulnerable service he could exploit your whole system.

This is the world’s most stunning new Android phone – and it’ll only cost you $5,000

FSF's High Priority Project List Now Has A Committee

The Free Software Foundation has now built up a committee to review their "High Priority Projects" list and they're looking for more feedback from the community. Nearly ten years ago is when the Free Software Foundation began listing what they viewed as the High Priority Free Software Projects in a list. This list has over time contained some definite high-priority projects related to freeing Java and Adobe PDF support and open graphics drivers to some more obscure projects of high priority like a free version of Oracle Forms, a replacement to OpenDWG libraries for CAD files, automatic transcription software, etc. I've personally called out many of the FSF HPP for what they're worth with my thoughts over the years.
