Appropriate Talks about Porn

There is currently some discussion about a talk which used pornographic imagery and jokes to illustrate points about Ruby programming [1]. A similar event happened in 2006 here is the description of the event from the author – which includes an unreserved apology [2].

It seems to me that the current discussion focusing on what […]

Australian Democracy is “Microsoft Compatible”

Here is the Australian Electoral Commission documentation on how to register a political party [1]. It includes the requirement for “A Microsoft compatible electronic membership list (and paper copy) providing the following information“.

So a prerequisite for registering a political party appears to be the ownership of a PC running Windows. While it may be […]

Real-World Car Safety Tests

The car safety tests that are required for every new mass-market passenger vehicle are flawed in many ways. Here is a list of the most obvious flaws (please point out any that I’ve missed):

There has been no research to make accurate crash-test dummies to represent women and children, and I believe that there has […]

Google Server Design

Cnet has an article on the design of the Google servers [1]. It seems that their main servers are 2RU systems with a custom Gigabyte motherboard that takes only 12V DC input. The PSUs provide 12V DC and each system has a 12V battery backup to keep things running before a generator starts in the […]

Why Cyrus Sucks

I’m in the middle of migrating a mail server away from the Cyrus mail store [1]. Cyrus provides a POP and IMAP server, a local delivery agent (accepting mail via LMTP). It is widely believed that Cyrus will give better performance than other mail stores, but according to a review by linux-magazin.de Dovecot and Courier […]

Maildrop, IMAP, and Postfixadmin

I have recently configured my mail server to use IMAP. I started doing this when I was attending Linux.conf.au so that I could read urgent mail using my EeePC while at the conference and then be able to deal with the more complex stuff using my laptop later on.

The next logical step is to […]

Employment Packages

Paul Wayper has said that he only wants to work for companies that will send him too LCA [1]. While that criteria is quite reasonable it seems overly specific. Among other things the varying location of LCA will result in the expense for the employer varying slightly year by year – which employers generally don’t […]

Per-process Namespaces – pam-namespace

Mike writes about his work in using namespaces on Linux [1]. In 2006 I presented a paper titled “Polyinstantiation of directories in an SE Linux system” about this at the SAGE-AU conference [2].

Newer versions of the code in question has been included in Debian/Lenny. So if you want to use namespaces for a login […]

Gmail and Anti-Spam

I have just received an email with a question about SE Linux that was re-sent due to the first attempt being blocked by my anti-spam measures. I use the rfc-ignorant.org DNSBL services to stop some of the spam that is sent to me.

The purpose of rfc-ignorant.org is to list systems that are run by […]

Flash Storage and Servers

In the comments on my post about the Dell PowerEdge T105 server [1] there is some discussion of the internal USB port (which allows the use of a USB flash device for booting which is connected inside the case).

This is a really nice feature of the Dell server and something that would be useful […]
