The Cost of Reading

On 11th October 2008

Costly pile

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):

NET USE U: \\NETHOME\LOCID /PERSISTENT:YES /SAVECRED

The necessary username/password details can then be entered and should be stored, allowing the drive to be mapped automatically when the user logs on.

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

Team Fortress 2

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.
