class="posterous_autopost">A quick warning for those who use the S3 Firefox Organizer in Firefox on Windows and are contemplating upgrading to the new Firefox 3.6: S3Fox does not yet work in Firefox 3.6 and is automatically disabled when you upgrade. […]

Posting mini blog posts from Posterous

Back in December, I commented that I could, with a judicious bit of additional code in the open source GraffitiCMS codebase, accept posts from Posterous and publish them on this blog. Well, it turned out that it wasn't that brilliant a code change: it broke the validation for XHTML. So, this evening, I fixed up the current HTML and took another look at my code. […]

Megapixel Madness

Found this site this morning: Petavoxel, a brand new blog that so far seems to talk mostly about the hardware aspects of photography, especially about why the rush for more megapixels in a point-and-shoot camera is an exercise in stupidity. […]

Best case, Worse case, Amortized case

A couple of weeks ago, Hacker News pointed to an article about how bad hash tables could be in a worse case scenario. […]

MacBook hardware update

I have a second-hand black MacBook that I bought some 12 months ago (it's just over 2 years old by now, well outside any warranty) so that I could experiment writing iPhone apps. It's served me well. The only update I've made to it so far is to upgrade to Snow Leopard (OS 10.6), but it's about time I did some further upgrades, hardware related this time. […]

Understanding the Apple Kool-Aid

This past weekend, the touchscreen part of my iPhone 3GS became what I can only describe as insensitive: it would hardly register any gestures or flicks up or down, and taps to the upper part of the screen wouldn't register. I felt completely stupid tapping forcefully on the screen: it's not as if there's anything mechanical going on that would respond better to such vigorous actions. There was even a point when I couldn't flick the slider to power off the phone: it's at the top of the screen. […]

Handbrake 0.9.4 slower?

I use Handbrake and AnyDVD to rip DVDs I buy to iPhone/iPod Touch format so that I can watch them on flights. Since I fly quite often (to the DevExpress offices in Glendale, various conferences, home in England, etc), watching what I want to watch during these boring flights has been a life-saver, or at least a sanity saver.

768-bit RSA modulus factorized

RSA, a public key cryptography algorithm, relies for its security on the fact that factorizing a number that is the product of two large primes is hard. Very hard. […]

Academic paper on Swoopo

Ever since I read Jeff Atwood's article about Swoopo on Coding Horror, I've been fascinated about the strategies involved in bidding on such a site. Not fascinated enough (or indeed interested enough) to actually use real money of my own to do so, but to my mind it has all the hallmarks of some kind of remarkable result in advanced game theory. Basically Swoopo is an auction site where they're the ones putting up the items for auction. The suckers -- sorry, bidders -- bid for the items, but each bid costs money to place (something like 75 cents) and each bid extends the end time of the auction. […]

Bug with comments and GraffitiCMS

One bug with Graffiti that's been driving me nuts ever since I started using the app over a year ago is that it assumes that a commenter will naturally add the http:// to the beginning of their website name. If they don't, the code that displays the comment later will force the URL to be absolute (essentially by prepending the Graffiti application's base URL to the name). Of course that link is then nonsense and leads to a 404 if someone clicks on it later. […]
