Fujitsu ScanSnap S300

Fujistu ScanSnap S300About three months ago, as I was trying to gather documentation for my taxes to take along to my accountant, something finally snapped. I had all these invoices and statements and papers in a big old folder, and I was flipping through them, trying to find documents relevant to my taxes. In the closet in my office there's a bunch of other folders for previous years too. Ditto, the basement (oh, heck, I really need to sort it all out down there). It's a big mess. […]

Regular hexagons in Adobe Illustrator

Last night, I had to draw a regular hexagon in Adobe Illustrator, Now, I remember from my school days how to draw one with a compass and ruler (draw a circle with the compasses, and then select a point on the circumference and mark off radii with the compasses, going round the circle; you'll mark off six intersections and then connect them with straight lines: voilà!), but I don't have any compasses in Illustrator.

PCPlus 269: Drawing binary trees

I write a monthly column for PCPlus, a computer news-views-n-reviews magazine in the UK (actually there are 13 issues a year — there's an Xmas issue as well — so it's a bit more than monthly). The column is called Theory Workshop and appears in the back of every issue. When I signed up, my editor and the magazine were gracious enough to allow me to reprint the articles here after say a year or so. After all, the PDFs do appear on each issue's DVD after a couple of months. When I buy the current issue, I'll publish the article from the issue a year ago. Since I've just bought the issue for June 2009, here's June 2008's article. […]

Credit card fraud

We came home after a relaxing week-long visit to England to find that my direct debit to our gym was bounced by my Wells Fargo credit card. I logged on to my account on the bank's website to find that someone in Atlanta, GA, had been "using" my credit card to rack up about $7,000 in charges, all within a couple of hours on the day we flew out of Denver. I was at 38,000 ft when the fraud occurred. The charges had triggered the automated fraud system, and Wells Fargo put a hold on the card. From which, of course, automatic debit transactions started failing including the one for the gym. […]

Trying out Moblin 2.0 beta

Last night, I read about the new netbook OS, open source but funded by Intel, called Moblin. It’s been designed and implemented especially for Intel Atom-based netbooks, such as the Dell Mini 9 (Inspiron 910), and so I decided to give it a try. […]
