Displaying posts with tag: maxdb (reset)

It turns out....
+0 Vote Up -0Vote Down
I got a phone call the other day from someone asking about MaxDB MailDB. He said that he got my phone number from something he read online. I publish my phone number with a lot of my writings, as well as the url to *this page you're reading now*

So some people call me on it sometimes. I might have to put up an asterisk filter some time if I get too many calls.

He called me to tell me that MailDB is the new Jesus Christ and that I should *sell sell sell*!!!! (!!!)

He didn't put it quite that way, but that's the gist of the conversation.

Those of you who are interested in buying, please accept a license to the following code under the GNU GPL:

I spoke with my manager about working on this code for MySQL during work hours. That means that any work I do on it belongs to MySQL, Inc., and would be licensed to the community under the GPL.

SAP.info article on MaxDB
+0 Vote Up -0Vote Down
Hey all,

Cross posting some work-related stuff here, since I haven't quite decided whether I like movable type or not...

http://www.sap.info/goto/en/go/29707/

And while I'm at it...

What does the community want to see out of MaxDB in 2006? What are the main areas we should focus on this year? What would make your experience of using MaxDB better? Easier? More enjoyable?

I don't know how well trackbacks work, so you may feel free to email your suggestions to maxdb@mysql.com if they seem to be broken :)

Hey all,

I hear that the collective "you" are annoyed by all of the technical bits on this blog. So I've decided to move non-personal blog entries to my movable type server at mt.colliertech.org. Specifically, work blog posts will be made to

http://colliertech.org/~cjcollier/mysql/

If this works well and I start making lots of posts, I will have the planet mysql aggregator point to the new atom feed:

http://mt.colliertech.org/mysql/atom.xml

good fun, that. For those of you who don't read this blog to get new and juicy bits of information about MaxDB and MySQL, rest assured that posts to this blog will now be easier to consume :)

My sound card wasn't working, so I installed ubuntu. now it works. I wiped my old testing version of maxdb and am now using the debian version.

I am going to see about making a synch manager debian package if one does not already exist.

3d printer
+0 Vote Up -0Vote Down
What do y'all think of the idea of a 3d printer? Aaron uses one at work. They call them "C&C machines." I don't recall what C&C stands for, but it basically takes a 3d model from a computer and cuts it into a piece of metal. I've been thinking about building such a beast.

Since there are a lot of data related to such a task, I figured I could get mysql and maxdb involved. Feedback?

I still need to read it a few times and try it out myself, but here is the link so you can follow along :)

MaxDB talk at MySQL UC 2006

[Error: Irreparable invalid markup ('') in entry. Owner must fix manually. Raw contents below.]

My proposed talk got accepted for the 2006 MySQL UC.

I'm working with
Chris Hall to get the Synchronization Manager functioning stably on Linux and Mac OS X. I'm going to tag blogs having to do with this purpose with "mysql uc 2006", in case you're interested in following along.

Chris has been putting a great deal of effort into getting MaxDB -> MySQL synchronization working smoothly and has offered up the documentation of his experience for the good of the community.

He has not stopped there. In fact, he has now gotten the Synchronization Manager running on OS X. We expect both of these features to be working well enough by the 2006 UC to present them to the community and have a public

Description of MaxDB code tree
+0 Vote Up -0Vote Down
I had a conversation with Daniel Dittmar, one of the developers on the SAP team today. I am trying to get familiar with the MaxDB codebase, and it's difficult to do without at least a bit of explanation. The inline English documentation is written by native German speakers, so it's often difficult to discern. Having this map will help me quite a bit. I hope it helps some others as well.

Thanks very much to Daniel for putting an evening in to documenting this.





12:56 DanielD: can you point me to some docs on the maxdb source code?
12:56 why are the different parts named with such short and
difficult-to-remember names? :)
12:57 partly, because if you work with them day in, day out, you
remember them anyway and they are easier to type

Meeting with Patrik today
+0 Vote Up -0Vote Down
I met with my boss, Patrik today. We discussed some of the work I've been doing the last quarter, the direction we're planning on going and some of the expectations for the next quarter. I also completed my expense report for the trip to Germany in September. Finally.

I feel pretty special that someone would travel from Finland to Seattle in order to see me. Even if it's a stop-off on the way to Cupertino :)

We had lunch at the space needle after our meeting. Very good (and expensive) food there. As the restaurant rotated, I gave him the sitting tour of the layout of the city.

Afterwards, we drove over 520 and did a drive-through tour of Redmond and the Microsoft campus. We

More notes from UnixODBC + Maxdb

I built a simple ODBC program that attempts to connect to a data source and tells you whether the connection succeeded or not.

It works. Yay. I also moved the example config directory to the example directory, since that's what they are.
Hey, look! I'm published :)

New software, notes about work
+0 Vote Up -0Vote Down
I installed OOo 2 today. And I connected it to my locally running MySQL database via JDBC. I've been learning a lot about JDBC recently, what with a rash of customers wanting to know how to connect to MaxDB via Java.

I'm also working a bit with Peter Harvey and learning something about ODBC. It seems somewhat more complicated. Perhaps that's because it doesn't have a virtual machine to target. I don't know. They all seem similar to DBI.

I also installed the beta version of Thunderbird. The Debian package was a bit out of date and didn't have index-by-recipient. It was a major hassle for me, so I fixed it.

Ulf and I have been working with a potential customer who has been having issues connecting to his x_server with MaxDB SQL Studio. He was initially reporting that he could not issue a particular query. I tried to get it working locally and put together a

maildb code back up
+0 Vote Up -0Vote Down
Since I've been working a bit more on maildb the last week, I put the subversion repository back up. Sadly, the revision history has been lost for the previous version. All I had to restore it was the current checkout.

I believe the old revision history can be grabbed from the .svn/ folders in this tar file, though, if you need it:

http://colliertech.org/~cjcollier/src/maildb.tar.bz2

You may keep up-to-date by following the development in the online SVN:

My server was down for the last 3 weeks. This brings me to about a 98% uptime. Woe.

Did I mention I'm in Berlin?

I'm in Germany. Crazy.

I'm putting images up on my gallery page now, but it's slow going. It seems that I keep bringing down my co-worker's network whenever I push a lot of bandwidth over it.

I have not asked my co-worker if I can mention him on my blog yet, so I will not mention his name; But, I would like to publicly share my gratitude. He has been very kind and helped me find my way around his country very adeptly.

He suggested a very nice hotel for me, only moments from his office and home, was kind enough to invite me on an outing last weekend with his children to a local lake, keeps me hydrated (Have I mentioned how uhm... different Berlin water is than Washingtonian water?), lets me invade his network, and keeps me very well informed about MySQL, SAP and MaxDB.

I miss you all. Please comment so I have some sort of tenuous grip with home. I'm

MaxDB Synch Manager, Part the second: Verifying installation

Welcome to the second installment of my
articles on the MaxDB Synch manager. In the rough draft of the previous article, we covered
installing MaxDB and related client packages.




Launch First Steps


As you will remember from the first article, we are now at the
point of doing what the installer calls launching the first steps.



When the button on the installer is clicked, a brower opens a file
that the installer placed on my hard drive. For those of you without
access to my hard drive, I will post this file on
my web server
for easier viewing. Do note, however that this file
in its current state is out of date, and we do not suggest using it as
a reference.
