Why end-users shouldn’t critizise on a technical level

August 16th, 2009 by TheBonsai

A rant! A rant!

Today, somebody (thanks exaltis on Freenode) provided me a link to an OSNews article during a discussion about X. He told me it’s fun to read – I clicked.

In this article (also read the comments), Thom Holwerda talks about why the X Window System is bad and Linux needs a different graphics architecture. This article is nice to read and discusses existing problems in some applications and X server software.

All problems he talks about are real, yes. I can understand that he’s pissed off. And he, as end-user, wants a solution and a stable system.

But his conclusions that these problems come from the design of the X Window System itself are just wrong and show that he doesn’t know what the design of X is. X has enough problems in its design, but none of them are related to the problems in his article. He talks about bad design, but he actually means bad implementation. Even his example with driver crashes or driver updates are completely irrelevant for the X design, the X Window architecture allows ways to implement this. That nobody does this doesn’t mean it’s a design problem.

From what I can see in the text he just would say to me that he’s a user and not a tech and he doesn’t care and he just wants a working system.

Yes, right, he’s a user. That’s why he shouldn’t conclude it’s a design problem, he should just talk about what he knows and not about what he thinks he knows.

Finally: BIND9 and Oracle RDBMS are compatible!

April 24th, 2009 by TheBonsai

This morning I had a really good start. Get the first cup of coffee, activate the NX session, open the IRC client, go to Freenode’s #oracle channel, and saw a question:

super noob question , how do i query my oracle database online, do i need to setup bind9 and allow incoming connections so it can be accessed

I just wanted to share that :-)

Have a good day!

Five hours, ORACLE, dbca, ASM and a customized SQL*Plus prompt…

January 31st, 2009 by TheBonsai

Yesterday was a bad day. I wanted to completely rebuild a database with a corrupt data dictionary. My plan:

  • Backup/exports
  • Shutdown DB, remove userspace files
  • Cleanup files inside ASM
  • DBCA to make new one (no scripts available)

You see, nothing unusual. So far so good, everything fine except the last step. The scripts I had from the first installation didn’t run through, so I just wanted to click something together. But DBCA spit out:

DBCA could not startup the ASM instance configured on this node. To proceed with database creation using ASM you need the aSM instance to be up and running. Do you want to recreate the ASM instance on this node?

Er.. what? ASM instance is up and running and some minutes before the old database ran fine with it! So what? Metalink, Google: Environment variables, Listener configuration etc etc etc. Nothing applied. The only thing I really knew 100% was that the ASM setup was rocksolid.
