I was saddened to read on www.timetriallingforum.co.uk that Sheldon Brown had died (see this obituary). Sheldon Brown's website is a fabulous source of bike information, particularly related to fixed wheel and tandems. He'll be missed worldwide.

I've just received a FrogPad portable keyboard, to use with the OQO UMPC I bought recently. It's Bluetooth enabled. The manufacturers claim one can reach 40wpm quite quickly, even for those who aren't already touch typers. I'm most definitely a "hunt and peck typist", so it'll be interesting to see how this gets on. Besides using the keyboard with the UMPC, I plan to use it with my (hopefully soon to be resurrected) iPaq hx4700 Pocket PC.

This is what a Righty FrogPad looks like (if you click on the image, you should see a life-size version). I bought the Lefty version, in white, with the intention that this would leave my right hand free for mouse or stylus use.

Physically, the unit seems pretty robust, with a slide on cover. It comes with a CD with a typing tutor (for Windows and Mac, but the Windows version seems to work OK on Linux under Wine), a retractable USB power cord and mains adaptor, and several leaflets and manuals.

Groklaw has a story linking the current MSOOXML deliberations to a Microsoft strategy document that's in the public domain thanks to at least one anti-trust case. (Note that it's a big pdf file, and that the groklaw story has it as text). The Groklaw story has many comments, and is worth reading. Is this normal behaviour for a company, or am I just naive?

Having looked at that document, this news story (Gates to tap young minds) sent shivers down my spine.

Well, actually, a bunch of American Baptists burnt an effigy of Richard Dawkins. It is pretty impressive that standing up for your views on life and religion can provoke such a response. On the other hand, they also burnt an effigy of Hillary Clinton (reportedly described by the fruitcakes as "a Hitler named Hillary Clinton – the anti-God baby killer who plans to turn the United States into Sodom and Gomorrah").

Wild stuff in the realms of a "god" who's believers claim is kind and benificent. Me, I rather like Dawkins' portrayal of the Old Testament god in The God Delusion. I notice the amazon.co.uk listing has garnered 700 reader reviews, which seem on first glance to be very polarised...

My friend and colleague Lynne Cox is chairing the organising committee of a meeting to be held at Oriel College, Oxford, in July 2008. This meeting promises to be an excellent opportunity for networking and establishing collaborations in this field. Lynne asked me to join the committee and design a website.

I have occasionally linked to news items relating to Microsoft's dubious tactics aimed at getting ISO ratification of its 6000 page OOXML file format as an international standard. Now the European Union has waded in with an investigation into Microsoft's actions. Reports from CNN and The Wall Street Journal. See also Groklaw's chronology page on office file formats, which provides a huge set of links to provide background to the situation

 

After buying a Squeezebox music player, I have recently been considering various formats I have music in, their relative merits (both sonically and aesthetically), and their convenience. Over the years, I've acquired a fair sized collection of vinyl records. To be honest, I rather like them - there's a sense of having to look after them, and the artwork of the sleeves has the capacity to be far superior in most cases to that of CD covers. Currently I use a Rega Planar 3 turntable for playback through a Naim Nait 3 integrated amplifier. They sound pretty damned good, too.

Of course convenience leads us all to CD. I have a good number of these now, and a Naim CD3 CD player.

What's prompted this discourse has been my purchase of a Squeezebox. This is a smart device, that runs an embedded Linux and hooks up through the wireless network to a fileserver holding audio files. The Squeezebox is in turn connected to the amplifier. It can play a wide variety of file formats, including mp3, ogg and flac. So. I've been ripping CDs to disk, and using the Squeezebox for playback. Is the quality good? Well, I guess not as good as CD, but that's countered by the sheer convenience!

XO Laptop: It's the Software, Stupid! - A nice post about how the OLPC empowers kids creatively. A riposte to a number of rather scurrilously negative posts circulating on the web.

Timetriallists spend rather an undue amount of time worrying about the aerodynamics of their bikes and of their body position on said bikes. I guess at least it's easier than training! Wheel aerodynamics are a frequent topic on discussion fora, but often the data are either non-existent or are derived from wheel manufacturers and are therefore unlikely to be impartial. As part of an ongoing review of bicycle wheels, www.rouesartisanales.com have put a detailed study of the aerodynamics of a variety of bicycle wheels online. The study has previously been published by the magazines Tour and L'Acheteur Cycliste.

The test setup

As with most such tests, the basis here is that the wheels are placed in a wind tunnel (the web page has some detailed images of various elements of the setup). The wheel under test appears to be fixed to an inverted fork, on which there are electrical strain gauges - effectively, these are what assesses the aerodynamic drag. The wheels are said to spin in air air flowing along the wind tunnel: it's not clear whether the wheels are driven, whether they spin due to the air flow, or whether this refers to a pivot that allows the wheel to experience air flow at different angles of attack. Drag was measured at wind angles 0 to 35 degrees. Because the more extreme win angles are infrequently experienced on the road, it seems that an average drag value is computed by giving less weight to the more extreme angles, and greater weight to smaller angles. This is indicated by the Gaussian curve in the graph.

My Pocket PC (an HP iPaq) broke recently, and while I was scanning various online emporia for a replacement, came across the OQO O+ UMPC, which was a clearance item at Expansys. Since one of the main reasons for using the Pocket PC was as a means of tracking my cycle training, I thought a miniature PC running WinXP might be useful. The other significant use would be for delivering presentations. So, how does the device stack up? And given this is the old model, now replaced by a slightly more powerful device running Vista, are these comments valuable?
