I have a friend who needs some Adobe Acrobat automation. The project description is:
We need to find a programmer who is willing to do some high-end Adobe form work for us.
We need to embed a "send to" button in some of our company forms so we can email the form to clients who can input the data and submit the form back to us by clicking on a submit button on the form.
If anybody has this

currently working on a refactoring ndbapi for mysql-cluster, in order to decrease
mutex contention allowing to better utilize many threads on multi-core machines.
while doing so, i implement a "vanilla" ndbapi-backend which lacks features
current in there.
once this is working, i'll start adding optimizations...
reintroduce:
- zero copy receive
- optimizations for single threaded performance (less ctx switches)
introduce:
- split mutex(es)
- zero copy send (or actually 1-copy instead of 2, but zero sounds better)

Here is a blog entry that was sitting in my Drafts folder for a long
time
(just because I didn't realize :). Anyway, it shows how to install Open Solaris 2008/11
on Virtual Box.
The original install was done using Virtual Box 2.0.6. I installed
Virtual Box 2.1 this morning and the image was easily recognized by the
updated Virtual Box.
Here are the basic steps.
Create a new VM ...
As part of the previous step, create a new Virtual Disk mapping to the downloaded Open Solaris image ...

A while back a Sun engineer posted an article claiming that the best way to scale MySQL is to shard your database in many instances on a single server, each of which runs in threads that individually have low performance. The Sun way has always been to get high throughput with high latency. [...]

I’ve been collecting a bunch of tabs, MySQL related, that I think people might have missed during the holiday period.
Contrarian Minds: Marten Mickos - this is a great interview with former CEO of MySQL, now SVP of the Database Group, at Sun Microsystems. Its got a bit of interesting history, and thoughts about the future. There’s also some interesting photography.
Facebook is now at 150 million users. They grew quite a bit recently, it was just 140 million about a month or two ago.
Flickr has seen traffic reaching ten terabytes. As you know,

As usual, you can likely ignore the “Menlo Park, CA” part (I haven’t checked though… but am 99% sure).

Today, Dinesh pointed us out to the fact that MAMPU/OSCC saves RM40 million with open source. That’s about USD$12 million dollars!
I quote, from the report:
Savings on licensing fee alone by adopting OpenOffice.org have already exceeded RM12 million, which is based on the total installed seats of 12,760 at public sector agencies.
Also, from the same report:
The top three applications being considered by most Public Sector Agencies are:
1. OpenOffice.org ? Office Suite
2. Firefox ? Web Browser
3. MySQL ? Database using Open Source Technology
That is impressive. OpenOffice.org and MySQL both come from Sun Microsystems Inc. Of

People keep asking me about components that make up large scale systems. Below is a dump of the systems I typically see/build. I am sure people draw pretty pictures, but to me it is more of a check off list :)

- Relational
This operation is typically split between two different
groups. One group uses data for presentation layers and for
the feeding of live requests. The other group does data
analytics for traffic, etc. A third group will also exist in
some cases to do work for "near time" responses. That data is
used to handle DOS attacks and other security related
features.

- Geographical

A feature of the MySQL server that is used a lot, and yet is a source of much user confusion, code complexity, and multiprocessor lock contention, is logging. Query logging, slow query logging, and the new 5.1 feature, "log to table".
I've removed most all of that stuff from Drizzle (and removed two or three sets of now-no-longer-necessary mutex locks in the process), and replaced it with hooks into a logging plugin subsystem, and have implemented two plugins for it. One logs to a file, and the other logs to syslog.
The output looks almost completely unlike the current MySQL logging. There are no hash-prefixed pseudocomments, for one thing. And there is no distinction between the query log and the slow query log. Queries get logged, and the amount of time each query takes gets logged with it. This subsumes the "micro-slow patch" that is spreading around in the MySQL legacy [Read more...]
