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

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

Posted by mark on February 3, 2010 under Technology

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

Posted by mark on October 23, 2009 under Technology

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 »
