Running on WordPress!

I’ve decided to try out the real deal — a ‘proper’ weblogging platform, namely WordPress. Be sure to comment if you spot problems…

Grumpiness and Cigarettes

Meta: My apologies if you wound up running into me online at some stage this week — I’ve been in a lousy mood.

Where the ‘cursor’ came from

Stuff: So C is a massive antiques nut, and got tickets for the Antiques Roadshow next month in LA. As a result, we’ve been shopping around for interesting stuff for her to bring along.

The Life of a SpamAssassin Rule

Spam: during a recent discussion on the SpamAssassin dev list, the question came up as to how long a rule could expect to maintain its effectiveness once it was public — the rule secrecy issue.

‘Irish EFF’

Ireland: There’s been some discussion about ‘an Irish EFF’ recently, reminding me of the old days of Electronic Frontier Ireland in the 1990s.

Happy Birthday to the RISKS Forum!

Tech: One of the first online periodicals I started reading regularly, when I first got access to USENET back in 1989 or so, was comp.risks — Peter G. Neumann’s RISKS Forum. Since then, I’ve been reading it religiously, in various formats over the years.

Patents and Laches

Patents: This has come up twice recently in discussions of software patenting, so it’s worth posting a blog entry as a note.

looking at the new DKIM draft

The combined DKIM standard, mixing Yahoo!’s DomainKeys and Cisco’s IIM, has been submitted to the IETF as a candidate spec by the MASS ‘pre-working group effort’. I like the idea behind both (a few years back, I, a few other SpamAssassin developers, and several others came up with the roots of a message-signature anti-forgery scheme we called ‘porkhash’, but never really went anywhere with it), so I’m glad to see this one progressing nicely.

McCreevy seeing anti-globalisation protesters everywhere

Patents: I’m just back from a fantastic holiday weekend, totally offline, hiking through Catalina Island. I’m a little bit sunburnt, my nose is peeling, but it was great fun. I got a fantastic picture of the sun setting over hundreds of boats bobbing at their moorings in Two Harbors, which I must upload at some stage.

The meaning of the term ‘technical’ in software patenting

Patents: One of the key arguments in favour of the new EU software patenting directive as it’s currently worded, from the ‘pro’ side, is that it doesn’t ‘allow software patents as such’, since it requires a ‘technical’ inventive step for a patent to be considered valid.

Latest Script Hack: utf8lint

Perl: double-encoding is a frequent problem when dealing with UTF-8 text, where a UTF-8 string is treated as (typically) ISO Latin-1, and is re-encoded.

Amazing article series on Climate Change

Science: in April and May, the New Yorker printed an amazing series of articles on climate change by Elizabeth Kolbert, full of outstanding research and interviews with the key players.

Flickr as a ‘TypePad service for groups’

Web: a while back, I posted some musings about a web service to help authenticate users as members of a private group, similarly to how TypeKey authenticates users in general.

DVD annoyances

Hardware: I’ve been needing a decent backup solution, since I’ve got 60GB of crud on my hard disk that isn’t being rsynced offsite yet. So I bought myself a nifty DVD writer from woot.com a week ago, supporting DVD+RW, DVD+R, DVD-RW, and DVD-R, and a spindle of 20 DVD+Rs from Target. Little did I realise the world of pain I was entering.

European swpat update letter

Patents: Ian Clarke copied the FSFE-IE mailing list with a good mail he sent to Mairead McGuinness MEP, detailing the current state of proposed fixes to the European software patenting directive. He discusses a comment from an Ericsson employee asking for software patentability:

Getting JuK to output sound via ALSA

Linux: Linux sound is still a mess. Due to the ever-changing ‘sound server of the week’ system used to decide how an app should output sound, it’s perfectly possible to have 3 apps on your desktop happily making noise at the same time, while another app complains about requiring exclusive access to /dev/dsp — or worse, hangs silently while it attempts to grab an exclusive lock on the device.

Patents come to computer gaming

Patents: in a recent discussion about games and patents, it emerged that these common elements are patented:

Irish Oireachtas take care of their own

Net: Fergus Cassidy reports that ‘bandwidth-starved TDs and Senators’ in the Oireachtas will be taking a shortcut around Ireland’s woeful consumer broadband situation, especially in terms of deployment outside of the main urban areas.
