Video Camera for Shared Movies

I have never felt inclined to create content for Youtube due to the low resolution of the display and the fact that only one format is supported (Flash which is totally non-free).

The existence of blip.tv has inspired my interest in creating videos for distribution on the net. blip.tv has higher resolution than Youtube and […]

Slicehost vs Linode

Six months ago I investigated the options for Xen virtual servers [1]. I ended up receiving an offer of free hosting and not needing that, but the research was useful. There is a good range of options for Xen servers with different amounts of CPU power, RAM, bandwidth, and disk space. There are a couple […]

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 […]

Integrity and Mailing Lists

One significant dividing factor between mailing lists is the difference between summary lists (where the person who asks a question receives replies off-list and then sends a summary to the list) and the majority of mailing lists which are discussion lists (where every reply goes to the list by default).

I have seen an argument […]

The Latest Dick Smith Catalogue

I was just reading the latest catalogue from Dick Smith Electronics (a chain of computer stores in Australia).

The first interesting thing that I noticed is that laptops are cheaper than desktops in all categories. For any combination of CPU power and RAM in a desktop system I can see a laptop advertised with similar […]

Combat Wasps

One of the many interesting ideas in Peter F. Hamilton’s Night’s Dawn series [1] is that of Combat Wasps. These are robots used in space combat which may be armed with some combination of projectile weapons, MASERs, thermo-nuclear and anti-matter weapons.

In a lot of science fiction the space combat is limited to capital ships, […]

Some RAID Issues

I just read an interesting paper titled An Analysis of Data Corruption in the Storage Stack [1]. It contains an analysis of the data from 1,530,000 disks running at NetApp customer sites. The amount of corruption is worrying, as is the amount of effort that is needed to detect them.

NetApp devices have regular “RAID […]

Future Video Games

I just watched an interesting TED.com talk about video games [1]. The talk focussed to a large degree on emotional involvement in games, so it seems likely that there will be many more virtual girlfriend services [2] (I’m not sure that “game” is the correct term for such things) in the future. The only reference […]

The Problem is Too Many Remote Controls

I am often asked for advice about purchasing TVs and consumer electronics. Not that I am any great expert in those areas, but my general experience in specifying and purchasing electronics goods in related to my computer work does translate to other areas (and I know where to find advice on the net).

As part […]

Laptop Computer Features

It’s not easy to choose a laptop, and part of the problem is that most people don’t seem to start from the use of the laptop. I believe that the following four categories cover the vast majority of the modern use of mobile computers.

PDA [1] – can be held in one hand and generally […]
