"Vendor" Source or Openend Source

Maria Winslow blogs about "Vendor" Source , as a new term to refer to proprietary source code, no really this is just stupid, it's proprietary they don't like as a word but they keep their code proprietary. "Ceci n'est pas une pipe ?"

So what about a name for a formerly Vendor project now being open sourced We could call it Shared Source .. oh no that's something else.. so let's call it "Opened Source"

History repeated

This thread is almost exactly the reason why I started looking at SSI style clustering, and back then Mosix in particular , well. ages ago :) Things evolved but even with MigSHM in place a SSI style cluster doesn't solve your problem when you try to scale a database.
But how DO you scale a database ? Things have become a bit more easy lately when you combine MySQL-Cluster with LVS , however we still need to figure out a way to do similar stuff for large databases. We really really need this disk storage feature for MySQL cluster some day :)

RMS at Fosdem

I was about to write on this topic earlier but never came around actually doing it.
Ploum is so right about RMS.

Fosdem lost a valuable half day of conference because once again they scheduled RMS.
So before Fosdem I took a poll and asked about 50 people that planned on going to Fosdem if they were going to see RMS. Guess what .. only 1 guy planned to go .. and he said he wanted to go ther for a good laugh, guess what .. he didn't even go. People claim Fosdem is 2 days, no it isn't it's 1.5 day, really .. nobody cares anymore about RMS, not for the 5th year in row.. We've seen him too much giving the same talk over and over again. He became a parody of himselve .. altough he has some valid points about freedom Fundamentalism is never a good thing ever, and that's where RMS misses the ball..

Don't get me wrong, I respect RMS for what he has done, but there must be other interresting people out there that can give a keynote at fosdem next year, RMS might even be there given a talk, but get him out of Janson

Anyway I want my Tea now !

Karanbir Singh - Thinkability - Travel in and pre-Fosdem drinks

Sorry about the beers, I've had lots of people commenting me on my "Everything is a fscking dns problem" T-shirt but I didn't see anyone wearing a Cent-OS T-Shirt either

The beers will have to wait till the UKUUG Lisa then, I`m sure it will be lots easier to find me as I`ll be presenting a talk there :)

Undeleting a deleted Wikipedia Entry

In an earlier posting I ranted about wikipedia wanting to delete the 10th Floor Test entry I wrote.

I just got word from Steve Traugott himselve that he started the discussion again with some valuable arguments. So now the entry is being listed for undeletion

The whole story makes me wonder, since when did google became the authorative source of the truth ?

As I`m sure google finds this blog entry I`ll expand the entry here :)

So here's my new suggestion for the 10 floor test entry for Wikipedia

The 10th floor test , is a term first used by Steve Traugott from It referes to the ability to take a random machine in your infrastructure , drop it from the 10th floor, and not lose sysadmin work. Hence to be able to restore your infrastructure to working within 5-10 minutes. Steve was working in the tenth floor lab at Chemical Bank's midtown NYC headquarters building at the time he started using the term. The term is gaining widespread acceptance in the IT Infrastructure area and has been explained by different people at Unix and Infrastructure conferences

Upgrading and Upgrading

Upgrading MySQL-Cluster

So MySQL Cluster is heading towards disk storage , time to upgrade my development environment in that direction.
After the upgrade I ran into the following problem

mysql> create table blah (i int, c char) engine=ndb;
ERROR 1005 (HY000): Can't create table './test/blah.frm' (errno: 4009)

And the mysql error database doesn't really help :)

perror --ndb 4009
OS error code 4009:  Cluster Failure: Unknown result: Unknown result error

In the ndbd log it showed that the MySQL nodes connect but never really continued to start, strange no more logs and no help on the error.
Took me a while to figure out that MySQL-Max wasn't upgraded . MySQL-Max used to be required for NDB (dunno if it still is) and all of MySQL packages were already at 5.1.6 except for the Max package which deamon was actually running and which was still at 4.1.12 :)

You obviously know what I'll be testing next :)

Fedora Upgrading.

Has it ever occured to anyone that each time you want to do an upgrade of a Fedora Core box. either online or via CD it always fails because your / or /usr/local or whatever filesystem isnt' big enough. Each time you run into the dreadfull "Need 128Mb more free space on /" actually when upgrading from CD it used to just
crash witouth this error. Dunno if that is alraedy fixed.. filed a bug ages ago on that iirc. Anyway apt-get dist-upgrade is running on my iMac now :)
