It's been four years since I started working with open source
software and started on the journey to create opentaps Open Source
ERP + CRM. Sometimes I look back and think about all the
things that have happened, and what I've learned from the open
source experience, which is a lot, but a few things stand
out:
It's All About Great Software
When you give away the code, there's nothing left to hide. People
can -- and will -- judge every aspect of your software:
stability, ease of use, code quality, even architecture. Because
of this, open source software tends to stand much more on merits.
This is why you often will see new open source projects leapfrog
past projects with big-name backers or lots of hype.
There is Only One Community
It took me three years to figure this one out: when you create
open source software, you're not off on an …
I am happy to announce the release of mylvmbackup version 0.8. mylvmbackup is a tool for quickly creating backups of a MySQL server's data files. To perform a backup, mylvmbackup obtains a read lock on all tables and flushes all server caches to disk, makes an LVM snapshot of the volume containing the MySQL data directory, and unlocks the tables again. The snapshot process takes only a small amount of time. When it is done, the server can continue normal operations, while the actual file backup proceeds.
Below is the list of changes since version 0.6. You may wonder what happened to version 0.7 - it had a rather short life cycle as I was informed about a bug that I fixed quickly before I made a wider release announcement of 0.7.
- Fixed a bug in the InnoDB recovery function: the second mysqld process …
Kevin Murphy just posted Tip of the Day ? max_connections and I thought it might be nice to know what people actually set this to so I’ve created a Survey “What’s your max_connections” (totally anonymous).
For the record, while a consultant the record for a production
system was 9,500. Yes you read right, and I might add the
client was running a 32-bit OS as well, just to boot.
Apparently they had also tested they could get 9,500 connections,
problem is they didn’t do anything with the connections, so
didn’t see any per thread memory usage, and I did not get
confirmation of how the actually system memory usage was used
during the test.
I got my registration for Google App Engine this morning after being Waitlisted previously.
Between flying for about 15 hrs tomorrow and then the 2008 MySQL Conference & Expo where I’m presenting and running an Exhibitors booth, fat chance I’ll get to look into this much over the next week.
Pity!
I’ve noticed a change of buttons lately on sites where you can bookmark/share the relevant information. So I’ve done a cross sample of A Computer Site - www.dell.com, The MySQL Acquirer - www.sun.com, A News site - www.cnn.com and a technology information site - www.techcrunch.com
What got me to go back and research is I’d never seen a FaceBook icon before, or perhaps I’d never paid enough attention.
At the end most sites now wash out to a site called Add This.
MySQL Backups Using ZRM For MySQL 2.0
Zmanda Recovery Manager (ZRM) for MySQL simplifies life of a database administrator who needs an easy to use yet flexible and robust backup and recovery solution for MySQL server.
I've finally come off the waiting list - and my entry to the
Winter Rickshaw Run 09 was accepted. I will be
spending Christmas and New Years in India, then off for two weeks
driving a vehicle that looks like this:
Yes, two weeks. All of our possessions with us. It's just going
to be me and my (other) Australian team mate. Danger, excitement,
and probably bad hygiene awaits. If you have suggestions for a
team name (team "autocommit=1", "follow the sun"?), or sponsors I
should approach let me know!
Welcome, readers, to the 92nd Log Buffer, the weekly review of database blogs.
Brian “Krow” Aker started an interesting blog-thread with his post, The Death of Read Replication, the crux of which is that object caches, such as memcached, make the DBMS itself a little less central, particularly in “Web 2.0″ scenarios. “What does this mean? Less database servers. Bringing down your load means you push off the load to another tier. . . . Why do I need to go through MySQL at all… unless I just want it as a backup or for ad-hoc reporting?”
Ronald Bradford responds with …

Earlier this week I attended the Linux Foundation Collaboration Summit,
serendipitously held here Austin. It was a fantastic
opportunity to meet a lot of the people in the community whom I
hadn't met before as well as to catch up with old friends.

anyway)
There was an impressive line up of panels and speakers the first day of the summit …
