Moved some small but important backups to Amazon’s #S3. Better to have the most important things off-shore.

Just ordered parts for my #SheevaPlug from US to solder it an #ESATA port (2€ parts cost per port).

Have updated the #gentoo #binhost s yesterday, new readme http://bit.ly/cQuef6 in #overlay mirror at #github with addresses.

My #SheevaPlug crashed today, first time in six months. Full #backup is due anyway, so I have attached the HDD to my workstation for it.

It didn’t crash, the power supply of my #SheevaPlug fried. They didn’t use solid capacitors.

Now my #SheevaPlug has a internal lead-fleece battery as built-in #UPS, protecting it for about 40min. *yay* (Like Google’s deployment.)

Redis benchmarks on Amazon EC2 and Rackspace Cloudservers

Amazon and Rackspace both provide virtualized servers billed per hour. That makes deploying scalable applications, especially with distributed key/value stores, very handy: You could launch new servers just as load, customer count or requests increase.

Today I’ve run the Redis benchmark on the SheevaPlug, Amazon EC2 and Rackspace Cloudservers to see where a small Redis database will perform the best. Read more »

SheevaPlug Kernel and Gentoo binhost

geschenkboxYesterday I have played around with GIT and

  • merged the Linux kernel tree from Linus Torvalds
  • with the Orion sources from Marvell (i.e. patches for SheevaPlug and OpenRD)
  • added the Gentoo patches (distribution independent)
  • and those for USB displays and SDHC cards
  • and eliminated some harmless, but annoying warnings on ARM.

As I found the configurations of the other kernels for the SheevaPlug on the net a bit unfortunate, you can download my latest kernel flavour here: Read more »
