Never IRC as Root

Ben Fowler blogs about the issues related to running IRC as root. Google searches for (irc client exploit) and (irc client “buffer overflow”) give a number of interesting web pages. Many of the exploits require the user to perform an action that’s slightly unusual, but why take a chance?

The advice to not run as […]

Solar Hot Water – Not Expensive

The Australian has a new Environment writer named Matthew Warren who has a history of doing PR work for the coal industry. This has the potential for insightful articles based on knowledge of what the industry is doing or for PR work for the coal industry masquerading as journalism. Unfortunately it seems like the latter […]

Does Having Fewer Rules Inspire Hard Work?

I was recently talking to a client about the lack of guidelines for acceptable personal use of office resources in his company. He rejected the suggestion that he provide any real rules or guidelines (apart from some old rules that most employees were not aware of and of which there was no procedure to remind […]

Designing Computers for Small Business

Dell just sent me a letter advertising their new Vostro line “especially for small business“. They say “we listened, then we listened some more” and explain that it’s based on feedback from people in small companies. The problem (which should be familiar to everyone who has ever done any consulting work) is that people don’t […]

Base Load Solar Power

A frequent criticism of solar power is that the sun only shines brightly for part of the day, and that many of the times when there is significant electrical load (EG when people get home from work in winter) the sun light will be weak. One interesting solution to this problem is to store the […]

Water Prices and Scarcity

Due to climate change and population increases we are having increasing problems with the water supply in Australia. Peter Lieverdink suggests that we have more options for water supply including treated sewage similar to the Netherlands here he grew up. However I believe that in Australia we already do what he proposes (put treated sewage […]

Cheney Flip-Flopped on Iraq

Here’s an interesting CSPAN interview with Dick Cheney from 1994. It’s amazing how accurate Dick’s analysis of the Iraq situation was in 1994 when justifying the decision to merely destroy Saddam’s army in Kuwait and not try to occupy Iraq or catpure Saddam. It’s a pity that he didn’t stick to that idea.

Since the […]

The Start of My Computer Career

When I was about 11 years old I decided that I wanted a career related to computers. My first computer was the TEC-1 single-board Z80 based kit computer from Talking Electronics magazine (see the photo below). I think that I built this when I was 10.

The computer is 16cm high and 25cm wide. […]

LED Headlights in Audi Sports Car

It’s interesting to see that Audi is releasing a car with LEDs for all lights including the headlights. This is being promoted as an environmental benefit, however a quick google search revealed that my Volkswagen Passat apparently takes 55W headlights (giving a total of 110W of electricity used). Even allowing for some inefficiency in the […]

SE Linux vs chroot

A question that is often asked is whether to use SE Linux or a chroot to restrict a program.

In Unix chroot is a way of running a program with a restricted set of directories available (it used to be merely a sub-tree but with bind mounts it can be any arbitrary set of directory […]
