OSS Business Model?

Let me prefix this post by stating that I’m a developer and not a business analyst, but I wanted to point out something that strikes me as a bit contradictory. In recent posts like these by Savio Rodrigues and Matt Asay, there are references that say the commercial plugins MySQL/Sun was planning on releasing were part of an OSS business model. While the plugins would have been tied to an OSS project, the products themselves would have been commercial*. I think these products (and other current products MySQL/Sun offers only as closed source) should actually be considered as commercial product offerings (under a commercial business model), and not associated with a pure OSS business model. To me (and some may

Log Buffer #97: a Carnival of the Vanities for DBAs

The 97th edition of Log Buffer, the weekly review of database blogs, has been published on Brian “Krow” Aker’s Idle Thoughts.

We have Jeff Smith and Ward Pond standing by for two upcoming editions. And if you’d like to contribute, make yourself known in the DBA community-at-large (and have some fun in the process), you too can do Log Buffer! Read the homepage and send me, the Log Buffer coordinator, an email.

And now, Brian Aker’s Log Buffer #97.

Employee Log Buffer #97
Welcome to the 97th week of Log Buffer. I am Brian Aker, and I will be your cruise director :)

Synchronisation in via scripting in the Database? Jonathan Lewis has a write up on making use of a locking package for Oracle. How about some published release notes for Oracle 10gR2?

On the MySQL side we have a post about "Time Delayed Replication", or what I often refer to as "we break our databases a lot, so we would like some more length in the rope please".

Ever seen a DBA run through a data center in the hopes to pull the ethernet cable out of the back of a

Which open-source database do you use?

EnterpriseDB is sponsoring a survey to track which open-source databases people use. Make your voice heard: Vote today. It takes less than 30 seconds to answer, and covers such questions as why you use an open-source database, with which operating system do you use it, etc.

Employee SHOW INNODB LOCKS

If implementing ‘SHOW INNODB LOCKS’ took half an hour (literally, includes compiling and testing) for a non-developer type of guy (cause most of code was written anyway), why the heck it takes ten years (or more?) to get such feature to standard release?

A time to reap, a time to sow: A phased approach for open-source businesses

During my morning reading, I happened upon this verse from Ecclesiastes:

1 To every thing there is a season, and a time to every purpose under the heaven:...

2 a time to plant, and a time to pluck up that which is planted....

It made me think of the ongoing debate around open-source business models (illustrated well in a recent post by Savio and perhaps more so in the comments section to that post), kicked up by MySQL's recent decision to offer closed extensions to its core (100 percent open source) database, but one that has been simmering for a long time. MySQL is essentially saying, "We've spent a decade planting. We'd like

Useful ways of using Views
Here are a few ways I found Views to be useful for me.


Data Cleansing

If I have a column that needs to be cleaned or tested in some way. For example:
Select mycolumn, if(mycolumn is null, TRUE, FALSE) as mycolumnisnull from mytable
This example is not that amazing, but it lets you place conditions for the data. Then instead of re-writing these conditions in your application layer, you can re-use the View from the database.
Another example:
Select email, regex ['some amazing email verification/cleaning regex line'] as cleaned_emails from emails
Here again, we have some condition that placed in the database. We can now call the emails table and tell it to give us only the cleaned emails

Forums @ crazytoon.com is up!
I have thought about putting up forums on my blog for LONG time and even thought about writing my own. But after playing with phpBB3 for a while on my other site (http://totalplaystation.com/forum), I have decided to use it instead. Let’s just face it; I don’t have the time or resources to write [...]

MySQL ALTER table Progress Bar?

Altering a big table sucks, and to make it worse you have no idea what’s happening or how long it will take. I’d like a progress bar, or some status output, or something that gives me the feeling like my server didn’t die.
