Parallel processing as a silver bullet

28 05 2008

If you ever need to explain why parallel processing is not always the right solution, maybe you can use The Lawnmowers Law as an analogy for Amdahl’s Law. And I’ll throw in the silver bullet as well. Thanks must go to Doug and ultimately Jared Still for pointing to this article


Windows Live Writer

14 11 2007

I was reading about Live Writer today and the thing that caught my attention is that it was possible to create posts off-line and publish them later. Now it does not often happen that I am off-line, but there are times I do other things. And it would then be convenient to write and publish later. Hence the try-out. One cool feature that I don’t know from WordPress is adding a map. So

is where I live. Too bad I can’t change the text of this hyperlink.

The blog theme I have chosen apparently is not supported, but I’ll look into that later.

Everything you always wanted to tell about, but were afraid to

Doug Burns has started something that might become quite interesting. I hope there will be some excellent material in the comments on Doug’s post about something we all do once in a while. The people that Doug knows and read/comment on his blog didn’t become quite so good without their fair share of “Human Error” stories. There is an old Dutch saying; “Er is geen leuker vermaak dan leedvermaak” which translates to something like “There is nothing as funny as laughing about other people’s mistakes”. I can relate to that.

Please, don’t be shy and tell us your story. We can all learn from it.

MySQL for datawarehouses?

2 08 2007

Nothing to do with Oracle this time, but ‘competition’ needs to be followed.

It seems MySQL is expanding it’s possibilities: BlueLithium Selects MySQL & Infobright for Analytic Data Warehouse. My first impression is that MySQL is involved but that the actual database is from Infobright. The ‘engine’ for this MySQL implementation is from that company. I read this as ‘the kernel’ is not by MySQL, just the surrounding functionality. If you replace the kernel, is it still the same ‘database’? A matter of definition of course, but a different kernel will probably mean a whole new set of SQL-like functions and a whole new set of maintenance functionality. You can still call it MySQL, but is it still the same? I tend not to think so.

It is enough reason to be interested though, and the need to delve deeper into MySQL has increased.

When will I find the time?
