Slow CD / DVD Burning on Dell D820

Tagged with: — ondrej at 9:53 pm on Wednesday, December 27, 2006

Larry the CowI burned a DVD on my laptop, but it took ages :( The speed was between 0.5 - 1.3x; should be 8x. Arrrgh…
I was not able to enable DMA for the writer (TS-L632D). Fortunately I found a page with a solution.

Downloading Photos With Canon 300D

Tagged with: — ondrej at 10:29 pm on Tuesday, December 26, 2006

It is quite clear that downloading photos from a Canon 300D digital camera is very slow. It contains a USB 1 port — new cameras have a USB 2 or Firewire port or they are connected to a WiFi card.
I tested the speed of the camera (one year ago, but maybe it will be still interesting for somebody) and I compared the results to a USB 2 Hama card reader.

Ruby, DRb and Gentoo

Tagged with: — ondrej at 5:36 pm on Friday, October 27, 2006

Larry the CowThere can be a problem with the DRb system in Ruby on Gentoo and the IPv6 support.

If an application with DRb does not work and its error message is:

  1. Exception `SocketError’ at /usr/lib/ruby/1.8/drb/drb.rb:840 - getnameinfo: ai_family not supported
  2. /usr/lib/ruby/1.8/drb/drb.rb:840:in `getaddrinfo’: getnameinfo: ai_family not supported (SocketError)

then it is necessary to re-compile the ruby package with the ipv6 support, even you did not compile the IPv6 support into your kernel (or it is compiled as a module but it is not loaded).

Distributed Ruby

Tagged with: — ondrej at 5:26 pm on Friday, October 27, 2006

I am creating a prototype of a distributed application written in Ruby. Ruby 1.8 already contains the DRb framework, as a system for a communication of different Ruby processes, and the Rinda system too, as a naming service.
