psil presentation and compiler details

As promised last week , I've been working on making Psil work in a Python 3 environment. But first, a small but entirely relevant digression which includes a video of me giving a presentation: A few weeks ago, I attended Kiwi PyCon here in Christchurch. I had thought about maybe possibly presenting something when I signed up, but I didn't actually prepare anything ahead of time. ...

python 2 to 3 upgrade and exception handling

I've just (partially) upgraded Psil to Python 3. I had originally been developing it in Python 2, but there are a few particular things about Python 3 that make it a better choice. There's no particular reason it needs to run on Python 2, so I decided to not develop two parallel versions, and not try to run the same code in both Python 2 and 3 , but just upgrade wholesale to Python 3 and not ...

look before you leap

I started to investigate yesterday's idea of a shell implementation in Perl , and immediately got mired in the Byzantine shell quoting rules. The most basic thing about the shell turns out to be unnecessarily hard, and besides, it's already been done. Why did I think this was a good idea again? Somehow I had got it into my head that msysgit on Windows would only run from the msysgit shell. ...

earthquake widget update

Over the last couple of days, a few people have emailed me about my Earthquakes Widget which displays the most recent earthquakes on a small world map on your desktop (it's a Yahoo! Widget ). It seems that it had stopped displaying earthquakes due to an error loading the data file from the earthquake.usgs.gov server. It turns out that it was due to an URL change on the usgs.gov server, and ...

mandelbrot set viewer

...exactly the work that I've already done! Once again, somebody out there on the internet has already thought of the same idea. Nevertheless, I'm happy with my viewer (even though it's not everything I had envisioned yet) and I think I'll leave it as is and move along to something else. Finally, because this is Open Source Wednesday, you can find the code in ghewgill/mandelbrot on GitHub . Enjoy!

cherries

Well, not yet cherries. About a month ago, we bought a dwarf cherry tree for our front yard. It was essentially just a stick with roots at the time, not looking much like a tree at all. But we planted it and fed it, and it seems to be quite happy. Just in the last week or two, it has sprouted a full complement of leaves and is looking resplendent in its foliage! Apparently these ...

xearth bmp output, true colour, and fonts

Xearth has long had the ability to draw markers and labels on the image when it draws in a "live" context, that is in a GUI like X. However, it uses the native text drawing and font support to do this, so it never allowed the -label option when drawing to a bitmap file. I hacked support for labels into the Windows port a long time ago, using the Windows GDI support to draw text onto an in-...

the essence of the port hills

Last weekend I went for a walk up the Port Hills south of Christchurch. I cycled to the top of the road in Bowenvale Valley, then walked up the Hidden Valley track to the Crater Rim walkway, west across to the car park with a view of Governor's Bay, then back down Bowenvale Valley. It was a gorgeous spring day and the fruit trees were in full blossom. Here are some photos:...

open source wednesday: xearth

Years ago, I ported the classic Unix program "xearth" to Windows. Xearth displays an image of the Earth, as seen from your favorite vantage point in space, correctly shaded for the current position of the Sun. At the time, xearth had its own homepage and was updated every few years by the original author (Kirk Johnson). But a few years ago, I noticed that the original xearth home page had ...
