A Mind @ Play

Support for Renewables

We’ve had a pellet boiler installed at these premises for a number of years, and whilst generally pretty efficient and reliable, recently there were some problems which couldn’t be solved with the usual panache of just hitting it and telling it to work. The boiler, a 15 kW Künzel PL15 , had got stuck in a de-ashing cycle and would only intermittently fire up before returning to this cycle. Unfortunately, the firm which installed the boiler had in the meantime gone out of business, and our only option was to send for an engineer from a neighbouring county, which took several days, before the unit could be looked at. It turned out to be a problem with the microprocessor controller, the piece of kit which maintains the boiler’s high efficiency, though obviously beyond our capabilities to solve without sufficient technical knowledge (even the engineer who appeared on site had to call back to base for instructions that weren’t included in his handbook).

Rise and Fall of the Blogosphere

A recent Wired article has certainly provoked some controversy amongst bloggers. Claiming that blogs are history, and that Twitter, Flickr and Facebook are the future, the post’s author Paul Boutin recommends that anyone who’s thinking of starting a blog should stop, and anyone already writing one should pack it in.

Whilst I wouldn’t normally comment on a post of this ilk (given my feelings about bloggers who blog about blogging) it seems pretty clear that unless Boutin is giving us a tongue-in-cheek excuse for a debate on web trends, he’s essentially wrong in his assessment. After all, it comes as no surprise that Boutin proclaims the fall of the blogosphere from the comfort of a blog entry, nor indeed that he rails against his own ilk in decrying the “tsunami of paid bilge” that ranks highest on the Technorati charts. The idea that blogs should be abandoned on account of the fact that personal blogs rarely garner any extended readership or popularity calls into question why authors set up their blogs in the first place, and why indeed they should switch to other means if popularity is their main objective. Boutin upbraids blogs for being text-only affairs, a charge which I daresay isn’t especially accurate, particularly since it is easily possible these days to integrate precisely those services that are supposed to supercede blogs, such as Flickr or Youtube.

Capital for the Third World

I recently came across a wonderful idea for providing peer-to-peer lending to entrepreneurs in developing countries. The idea seems akin to the principles of the Grameen Bank, providing microcredit in this case primarily as a form of aid. The system allows people with spare cash to browse potential applicants and offer them money in the form of a loan. Kiva works with what they term experienced ‘field partners’ to provide the loans, these bodies being established and recognised sources of finance (which may charge interest on the money to the borrower). Eventually the loans are repaid and the money can be withdrawn, redistributed or donated to Kiva to help cover their organisation’s costs. Of course the levels of finance are fairly miniscule on the larger scale, a far cry yet from providing the many milliards needed to create the level of sustainability needed in many parts of the developing world, through stability, infrastructure, education etc. Yet Kiva has plenty of room to expand, and importantly the principle behind the organisation is sound, in trying to create a direct link between people in the developing world who need capital (and know what they want to do with it) and those with the money and the conscience to try and help. Time will tell how effective Kiva’s mission will be.

Ubuntu Grub Installation Errors

I recently installed Ubuntu on a system with a slightly irregular hard drive configuration. Two SATA drives were running Windows on a mirrored (fake) RAID array, and a third SATA drive was ready to have linux installed. The Ubuntu installer recognised the drive as the third hard drive, and installed itself as expected, with Grub installed in the MBR of this drive, being first in the BIOS’ boot queue. However, all references in Grub’s menu.lst for the Ubuntu installation pointed to (hd2,0), which resulted in an “Error 17: Cannot mount selected partition.” message from Grub. The solution was simply to edit the entries to read (hd0,0) for (hd2,0) as Grub now recognised the third drive as the first on account of its place in the boot order.

Don’t Extradite Gary McKinnon

This isn’t a case I’ve been following with any particular enthusiasm, but it would appear that Gary McKinnon is losing his battle against the extradition charges laid by the USA. Technically McKinnon was already arrested and prosecuted by the UK authorities prior to these extradition charges. In addition, the calls are made on the basis of a UK-US Extradition Treaty that was ratified after the events (and original prosecutions) and as such is being enforced retrospectively, allowing that the USA is not obliged to provide prima facie evidence for their claims. Whilst there are numerous issues regarding the Treaty that should already provoke concern, McKinnon’s case is clearly too small to spark a debate on the issue, and won’t involve politicians to the extent that extradition charges over a figure like Pinochet in previous years managed. Which of course, shouldn’t come as much surprise, since a man charged with torture of foreign nationals and assassination clearly has more to offer than a Weegie who crazily hacked into poorly protected foreign government computers on some wild conspiracy theory pursuing evidence of alien technologies and the secrets of ‘free energy’. It is therefore refreshing to see a campaign (see link above) organised to prevent the extradition proceedings, and guarantee McKinnon a trial on home soil. Unfortunately, the case looks liable to fail, however it can only be hoped that this failure will not prevent others from campaigning to stand up for those who lack the energies, finances and know-how to represent themselves and make an issue of their plights against large government and corporate bodies.

The Cost of Reading

As an avid reader, it often occurs to me just how second-hand book retailers manage to turn a profit. Even assuming the raw stock can be acquired at very little cost, the vast majority of books can go unsold almost indefinitely, all the while occupying shelf or storage space that costs money to maintain. I read somewhere that on average a second-hand bookseller can expect a third of his stock to be sold within six months, another third to be sold on an indefinite timescale, and the final third to simply go unsold. Obviously this has a knockon effect where turnover is slow. On a recent trip to Wigtown , Scotland’s National Book Town, I came across plenty of bookstores that clearly have to elevate prices to remain profitable. No doubt in their case, the annual book festival and holiday season are a major source of revenue that would otherwise cause most to close their doors in an otherwise small and overcrowded market ecosystem.

Dealing with Spam

If there’s one jargon term that every user new to the Internet soon becomes acquainted with, spam must near the top of the list. Its prevalence and virtual ubiquity through many forms of online communication have generated miniature industries devoted to dealing with it, and the science of spam detection, prevention and treatment almost resembles the tactical skirmishes of biological immune systems.

Spam exists in many forms, from bogus guestbook entries to elaborate instant messaging robots, but the variety which prompted this post was that classic form - unsolicited email. The level of penetration of spam illustrates itself in the number of systems put in place to combat it as standard on the vast majority of websites, including of course authentication emails and the ever evolving captcha. I use a small combination of plugins on this blog to block out most of the spam, and given the extreme sparcity of genuine comments, the potential for inconvenient ‘false positives’ is rather slim. Nevertheless, even the cursory inspection I tend to make over Akismet’s latest haul becomes tiresome for all the size of this blog - spam comments to date outnumber genuine ones by a factor of almost 500 (and that only counts those caught and tallied by Akismet). Quite how larger, more popular blogs deal with searching for false positives, I don’t know, but the task must be fairly time-consuming.

Mapped Drives in Windows XP

Having recently set up some network storage, I came across a rather irritating problem mapping network drives in Windows XP. The basic setup procedure, as outlined here , worked perfectly on some systems, but failed to retain the stored username/password for network attached drives requiring alternative login details. The solution found, courtesy of this blog, is to map the drives using the following command (replacing U with the drive letter, and NETHOME\LOCID with the relevant UNC network location):

Indiana Jones and the Kingdom of the Crystal Skull

The Indiana Jones saga was complete. He had trumped the Nazis, saved his father’s life, solved one of the greatest archaeological mysteries, and ridden off into the sunset with his companions. At least, until now. The recent spate of late-coming sequels and series restarts no doubt to a large extent prompted Indy’s return to the silver screen, and whilst this is no bad thing by itself, it does however spoil the rather nice ending to the previous series finale Indiana Jones & The Last Crusade . Although Sean Connery declined to come out of retirement for the film, the late Denholm Elliott sadly missed, and there being no part for John Rhys-Davies, the film’s still alluring combination of George Lucas, Steven Spielberg, John Williams and Harrison Ford will no doubt kick this film to the top of the box office. The problem is that the potential for disappointment runs almost as high as it did for Lucas’ own Star Wars Episode 1: The Phantom Menace, and one imagines that The Crystal Skull will only suffer as a result.

Assaulting the Team Fortress

Valve’s Team Fortress 2 is already over six months old, so now might seem like an odd time to write a post on the games merits, but with the recent release of the Medic Achievement pack, and the rather surprising (though not unwelcome) news that Valve intends to integrate some of its popular features and improvements into the ageing Day of Defeat: Source, I decided I’d jot down a few of my impressions.

The release of Team Fortress 2 came as something of a surprise, after so little news about its development, with virtually nothing concrete after the initial revelations in 1999. The finished version bears absolutely no relation to those initial screenshots, instead maintaining much stronger links to the original modification Team Fortress Classic, with a strong glossy coat of The Incredibles style graphics and an uncut, Columbian-strength injection of humour.
