Chess Blunder

By on December 5, 2006 in General

Good grief. What a blunder. I was playing a 12 minute game of chess against a human opponent on playchess.com and got to the following position –

Chess051220062.png

I was playing white and it was my move. I had about 3 minutes on my clock and my opponent had about 1.5 minutes. So no time pressure. So what did I play?

49. b7??

Really stupid move or what? Can you see why? Black can checkmate in a single move with 49 … Ng2#. Here is the position at the end:

I couldn’t believe it 🙁 I should have played 49. Rxf4 Kxf4 50. Kxe2 and then advanced the pawn on the b-file to Queen it. More study required I think to spot obvious mating positions. Here is the full game if anyone is interested:

Testing MacJournal again

By on November 26, 2006 in General

I’m having another look at MacJournal to see if it’ll work as my personal diary tool and also as a blog editing tool. I’m writing this entry using v4.1d4, which is the latest available development build from Dan Schimpf. The editor is nice. Probably a bit better than ecto form a Macintosh GUI perspective.

I was able to download all 190 entries from my Soapbox okay after pointing it at the base URL. When I tried this in a previous version it only downloaded a subset of them. Not sure if that was as result of something I did wrong or the program itself.

In theory I should be able to use this one program to compose and store both personal entries and public entries for the Soapbox. Anyone want to take bets on how long it’ll be before a private entry gets posted here 🙂

Here is a screen grab of this entry being composed in MacJournal. If picture uploading is working then you’ll be able to see it. If not I’ll need to do some more tweaking!

Update: Obviously pictures are being scaled to fit the column width. Have to fix that. Three options:

        • Find out if MacJournal can mimic the behaviour of ecto. The latter will include a thumbnail of the image in the post and will display the image in a new window when it’s double clicked. This would be my preference for a fix.
        • Amend the CSS templates for the WordPress theme to stop images being scaled. If anyone knows how to do this post in the comments.
        • Change the WordPress scheme to not use a single centred column. Might be time to go to a normal full window width theme anyway.

Update 2: The images are okay in the RSS feed from the site. Which is how everyone reads blogs anyway! Right?

Update 3: I’ve edited the picture to make it a thumbnail with a link to the larger version.

Michael Palin – Diaries 1969-1979 The Python Years

By on November 7, 2006 in General

Finished reading Michael Palin’s excellent Diaries 1969-1979 The Python Years yesterday. I loved it. It gives an inside view (abridged admittedly) of the birth of Python, the ups and downs and tensions within the group and the transition from the TV series to the films of the 1970’s. Palin’s thoughts on the Ripping Yarns TV series are very welcome as well. All in all a wonderful read. I note that on 12th July 1979 petrol hit £1 per gallon. It nearly hit that per litre a few months ago! I hope there will be another volume. I want to read about the making of the film Brazil, the making of the Monty Python’s Meaning of Life (I’m sure there where some tensions in that process), although the initial writing for the 4th Python film just makes an appearance towards the end of 1979 in this volume. Reading some of the entries I wondered how so many activities were crammed into some days. As a counterpoint to some of the hectic days we also read of Palin’s family life and more normal activities. I really enjoyed it.

David Gerrold wrote in his book World’s of Wonder that “…your first million words are for practice. They don’t count.” Meaning that to be a writer you have to write a lot of words. Like any activity you get better with practise. Want to play the guitar? Learn chords and practise. Want to be a good bowler in cricket? Get in the nets and bowl. Want to be a writer. Write lots of words, sentences, articles and stories. Practise, practise, practise. Good advice from Mr. Gerrold I reckon. I started a diary of sorts myself whilst reading Palin’s book. Mainly in response to Gerrold’s maxim on writing, rather than hoping the diary will be of any interest to anyone. No one will see it until i croak anyway! On a technical note I’m using the Journal feature of SOHO Notes as the place where I write and store my daily scribbling. I have a few articles and other ideas that I want to write and the more writing I do the better I’ll get at it!

Thank the maker for BBC Internet streaming

By on August 5, 2006 in General

I’m in San Francisco for Apple WWDC. When I was up in the wee hours this morning I was listening to BBC radio streamed over the Internet. A sanity saver when away if ever there was one. Said it before, but Radio 4 is worth the license fee on it’s own.

Isn’t US TV awful? Obviously they produce really good individual shows, Seinfeld for example, but the daily stuff is just dross. They do know how to do a mean bacon and eggs breakfast though 🙂

Walking and shopping planned in San Francisco today.

Nike+ iPod Sport Kit

By on July 20, 2006 in Technology

I got the Nike+ iPod Sport kit today and tried it out tonight. I don’t have a pair of the proper Nike shoes yet so I just stuck it under the insole of a pair of Caterpillar trainers I have. They have a thick insole so I was just aware of the sensor under my foot but it didn’t make it impossible to walk. It’d be uncomfortable to use it that way all the time though. I tied putting it under the tongue and laces of the trainer but it didn’t work there. I set it for a 2 mile distance program. It’s pretty cool. As I walked the distance counted up on the screen. It’s shown in 0.00 format so it goes 0.01, 0.02 etc. When I’d done half a mile the music faded down and the instruction voice told me I’d done half a mile. After a mile I was told I was half way there. At 1.5 miles I was told I’d half a mile to go. I had to stop after 1.75 miles as I the car park in Stormont was due to close!

When I docked the iPod it uploaded the data to the Nike+ web site and asked me if i wanted to visit the site. Here is the result –

I’ll need to get the proper shoes and calibrate it over a known distance. All in all I’m impressed.

Cocoa version of YAPT

By on July 12, 2006 in Science

As I said in a previous post I was switching the development of YAPT from REALbasic to Xcode. This was due to an overall slowness in the GUI in the REALbasic version. There was an irritating delay in activation and deactivating the buttons for each element when switching the application to and from the front on screen. Also the About… dialog box was sluggish in displaying. Add in the fact that REALbasic can’t create Universal Binaries for Intel based Macs yet.

The first development version of the Xcode Universal Binary version of YAPT is now available. It’s much snappier in use and uses the Cocoa framework and Applescript. Only Hydrogen and Helium do anything at present. I plan to finish the interface using these two elements and then add information for the other elements once I’m happy with the layout etc. I’d be interested in any comments. This switch to using Xcode and Cocoa means that YAPT will be Macintosh only. There will not me a Windows or Linux version. There are plenty of other Periodic Table applications for those platforms anyway. Actually there are several for Macintosh as well but I don’t like them 🙂

Herman Miller Mirra chair

By on July 3, 2006 in Technology

I needed a new chair to use at my desk. After much research I settled for a Herman Miller Mirra. It’s good. Still tweaking the various settings but so far it’s very comfortable and should help prevent back issues due to spending a lot of time at the desk writing, typing and computing in general.

YAPT update

By on June 10, 2006 in Science

It’s been a while since I posted about YAPT. I said I was going to release early and often. Not much has happened on the often front…

I’ve decided to develop this using Cocoa rather than REALbasic. This means that there will not be a Windows or a Linux version. I’m doing this for fun and recreation, and as such I want to use the Xcode and Cocoa so I learn how to use them.
