Using HTTP caching to improve performance

April 17, 2007

This Article from the BetterExplained blog is a pretty nice explanation of how to configure your server for better performance by using cache headers. Which complements nicely the article on Varnish I was just reading.

Caching is a great example of the ubiquitous time-space tradeoff in programming. You can save time by using space to store results.

WRT54G with OSX 10.4 DHCP problems

November 13, 2006

For anyone who has the problem that their 10.4 macs are unable to connect to their Linksys WRT54G router. then check out this thread in the linksys forums.

I upgraded my router to the latest firmware, everything was working fine, until I had to shutdown all my machines (for a pg&e scheduled power drop), on restart all the boxes came up but the macs couldn’t access the internet. Some time spent on frakking around revealed I was able to manually assign IP’s and DNS settings which pointed to a problem with DHCP.

It turns out the 1.01 firmware is broken for macs running OSX 10.4. you can downgrade the firmware in the router. to 1.00.9 but that might be a risk to some folks. so I have went with the alternative solution of manually assigning IP’s.

the firmware should be available from here. no news yet as to when Stinksys will be releasing a fixed version.
