bazaar - a distributed VCS or a new spin of the old RCS

December 4, 2007 late at night · Filed under Uncategorized

Like most people of my age, I graduated from RCS, to CVS, then to Subversion. Recently, a friend of mine implemented bazaar on  production servers at work and urged me to check it out.

I did.

  • It is written in python. some modules are written in C for speed.
  • functions are pretty much complete, yet the control of publishing is more of a P2P model.
  • Bazaar’s notion of personal branch is appealing. Any user can just start a branch and the repository database is stored in a directory named ‘.bzr’ right there, in the working directory.  This sounds scary, for sys admin and release manager alike who are more used to centralized RCS (revion control system). Yet, such a concept is really similar to what you do in the old RCS, you make a directory named ‘RCS’, then start to check in (ci) and out (co) .  If you don’t make a directory named RCS, the revision db file will coexisting with your working copy.
  • I don’t like the fact the revision db is right there with the working directory.

hashcash plugin caused a surge in trackback spam?!

December 4, 2007 late at night · Filed under spam, wordpress, wordpress plugin

Since I installed hashcash plugin for this wordpress.org blog site, comment spam has dropped to zero. So, it is effective indeed.

The wordpress hashcash plugin is easy to set up and less intrusive as Capicha! plugins.  However, it seems to be a surge of trackback spams after hashcash plugin choked comment spam inflow. Could it be the spammer actually has logic to detect hashcash plugin in their automation scripts?

I am uite sure the surge is only in eyes of the observer. guess I’d need to bite the bullet and apply for a wordpress.com API key, then enable kismet.
