/tmp /mnt/bind bind bind 0 0

Today I discovered that the above syntax works in the /etc/fstab file. This enables a bind mount of /tmp to /mnt/bind which effectively makes /mnt/bind a hard link to /tmp. The same result can be achieved by the following command, but last time I tried (quite some time ago) […]

AMD developer Center

This morning I received an email from the AMD Developer Center advising me that I need to fill out their NDA if I want access to their development machines.

I have a vague recollection that when AMD64 was first released I was very keep to get access to such hardware and had applied to AMD […]

comment-less blogs

Are comment-less blogs missing the spirit of blogging?

It seems to me that the most significant development about blogging is the idea that anyone can write. Prior to blogs news-papers were the only method of writing topical articles for a mass audience. To be able to write for a news-paper you had to be employed […]

what defines a well operating planet?

At OSDC Mary Gardiner gave a talk titled The Planet Feed Reader: Better Living Through Gravity. During the course of the presentation she expressed the opinion that short dialog based blog entries are a sign of a well running planet.

Certainly if blog posts respond to each other then there is a community interaction, […]

quantum evolution

On several occasions in discussions about life etc friends have mentioned the theory that quantum mechanics dictates the way our cells work. In the past I have not been convinced. However this site http://www.surrey.ac.uk/qe/Outline.htm has a very well written description of the theory which is very compelling.

IDE hard drives

I just lent two 80G IDE drives to a friend, and he re-paid me with 160G drives. Generally I don’t mind people repaying hardware loans with better gear (much better than repaying with the same gear after a long delay and depreciation), but this concerns me.

My friend gave me the 160G drives because he […]

The Squirrel and the Grasshopper

There’s a story going around the neo-con blogs titled “The Squirrel and the Grasshopper”. It was forwarded to me by a business associate with the claim that it’s “right on the money”. It’s strange that someone could be considered to be “right on the money” for Australia when essentially the same text is posted in […]

Debian SE Linux policy bug

checkmodule -m -o local.mod local.te semodule_package -o local.pp -m local.mod semodule -u local.pp

Save the following policy as local.te and then run the above commands to make semodule work correctly and to also allow restorecon to access the console on boot.

module local 1.0; require { class chr_file { read write }; class fd use; […]

SE Linux on Debian in 5 minutes

Following from my 5 minute OSDC talk yesterday on 5 security improvements needed in Linux distributions I gave a 5 minute talk on installing SE Linux on Debian etch. To display the notes I formatted them such that they were in 24 line pages and used less at a virtual console to display them. The […]
