More hardware failures this week: my Apple AirPort wireless router conked out, the third to do so. I had a spare; an older model with a bit less functionality. I now have a new, pretentiously named, AirPort Extreme Base Station which seems to be working. Its shape is a mini tower and will be a disappointment to my cat who liked to sit on the old, flat AirPort to soak up the heat.
Twelve years ago, I had the only wireless network among the nearby homes. Now, there are about a dozen, and that's not counting any with hidden SSIDs. At least most seem to be running automatic channel selection to avoid collisions. Things must be more difficult in a large apartment building, and also in large college dormitories where students are allowed to have their own wireless routers.
I might have been better off with a non Apple wireless router from Belkin or NetGear or maybe some other manufacturer, with a lower price or with even more functionality. But I am lazy and didn't want to spend much time fooling with installation and configuration issues. In particular, I didn't want to mess with a Windows-only installer when my only Windows machine, an HP notebook, broke last week and refuses to boot for unknown reasons.
I have to fix the HP someday, because it's the only machine which can run the software to connect to my DGT piece recognition chessboard. It's too bad that the warranty expired just last month.
There is some slightly scary news with using OpenCL, needed by Oscar in OpenCL mode, on some Apple hardware. It seems that some Macs have heat related failure with the lead-free solder used to connect certain discrete graphic processor chips. The solder joints fail after the GPU runs long and hot, and a program like Oscar will run a GPU as hard or harder than any other task. Even if this doesn't affect my Mac, it might affect someone's, and that's not good.
