• Multiple requests to server question

  - by embedded

  I have a DB with user accounts information. I've scheduled a CRON job which updates the DB with every new user data it fetches from their accounts. I was thinking that this may cause a problem since all requests are coming from the same IP address and the server may block requests from that IP address. Is this the case? If so, how do I avoid being banned? should I be using a proxy? Thanks

• bulk insert from Java into Oracle

  - by Will Glass

  I need to insert many small rows rapidly into Oracle. (5 fields). With MySQL, I break the inserts into groups of 100, then use one insert statement for every group of 100 inserts. But with Oracle, user feedback is that the mass inserts (anywhere from 1000-30000) are too slow. Is there a similar trick I can use to speed up the programmatic inserts from Java into Oracle?

• Way to call super(MyClass, self).__init__() without MyClass?

  - by Mark

  I find this syntax astoundingly annoying. Every time I rename my class, I have to change this call for no apparent reason. Isn't there some __class__ magic variable or something I can use at least? Interested in answers for Python 2.5, but it doesn't hurt to know if later versions fixed this.
