After some server tweaking to make better use of resources, and some code updates, my Diaspora* pod is much more stable again. Although it is written in Ruby, the footprint isn’t too large – and I am yet to resort to low memory versions of Ruby.
I have now posted from Diaspora* to both Twitter and Facebook. The interface looks more polished with every update, and new little features and bugfixes are coming along nicely. It is still very much in the Alpha stage of development, but is improving every day. The link to Facebook seems to be much more stable now. This may have been a temporary developer Facebook issue, as it would not previously allow me to enter the correct details for security.
I would also like to take a moment to remember Ilya Zhitomirskiy, co-founder and a developer of Diaspora*, who left us far too soon.
