I haven’t had a look at the Mail & Guardian blogspot for a while, but from the looks of it traffic is on the up :). It’s Friday night after all, peak blogging time! When attempting to read a post: Warning: mysql_connect(): Too many connections in /var/www/htdocs/drupal1/includes/database.mysql.inc on line 31 Too many connections
How much memory can a 2.6 Linux kernel address, part 2
As a followup to this post, about my debate with MySQL support, they got back to me saying yes, after all, MySQL processes on 32-bit machines can go beyond 2.5GB. Here’s their response: Hi! Yes, you are right. In HIGHMEM mode, a process can go theoretically to 3 Gb. If you have seen 3 Gb,… Continue reading How much memory can a 2.6 Linux kernel address, part 2
Climate Change
According to research by climateprediction.net, climate sensitivities due to increased greenhouse gases will vary between 2 and 11 degrees C, much greater than the range of 2-6 degrees C previously accepted. There’re still so many vested-interest claims going around claiming that global warming is still a theory, not proven, no need to change our behaviour… Continue reading Climate Change
How much memory can a 2.6 Linux kernel address
Busy having a debate with MySQL support about the memory limit for processes under Linux 2.6. We have a shiny new database with 6GB RAM, and the question is how useful is this with a 32-bit processor. As far as I know, processes on a 2.6 kernel can address 4GB. (there’s a reference on kerneltrap).… Continue reading How much memory can a 2.6 Linux kernel address
Google user-specified ads
Jeremy Zawodny has picked up another brilliant innovation from Google – user-specified ads. Don’t like the Google ads you’re seeing? (for example the ad for premium elk meat next to my post about vegetarianism). Simple – change them! You can read more at Inside Google and see an example at Consumer Affairs. The best ad… Continue reading Google user-specified ads
Moving to layeredtech
This is an update to the post Moving to Circular Systems. Circular Systems took a bit long to arrange their US server, so Anique cancelled the order, and thanks to the advice from Aubrey and Jacques, we’re trying Layered Technologies. So far so good, the server has been promptly set up and things seem to… Continue reading Moving to layeredtech
Yellow tongues and Google diagnosis
I knew I shouldn’t have used the Internet for medical diagnosis. I have a yellow tongue at the moment (no, I won’t attach a picture), and some of the possible causes of this are quite unpleasant, to put it mildly. I’d rather just have carried on flossing more regularly, or cut down on the turmeric.
Resistance
I practice tai chi in a class twice a week. Yesterday, my teacher told me I was resisting too much. No resistance is a key principle of tai chi. Physically, as soon as you resist, there’s an area for your opponent to grasp, push against and exert force. The idea is not to resist, but… Continue reading Resistance
Tectonic releasing print version
Tectonic have just announced the release of a print version. I wrote an article (in November or so, so hopefully not too out of date!) on MySQL that might be in it. But even if not, no reason not to drop everything and subscribe now! First two issues are free. Well done Alastair and Jason,… Continue reading Tectonic releasing print version
Sangoma graduation. Part 1: Vegetarianism
As I mentioned earlier this week, I was away from the 4th to the 11th, attending a friend’s graduation as a sangoma (note that the Wikipedia article needs some work!) in the village of Mtambalala, about 25 minutes drive from Port St Johns in the Transkei. It was a hectic experience, leaving me with lots… Continue reading Sangoma graduation. Part 1: Vegetarianism
