Twitter widget

2009-07-24T15:26:00.002+02:00

Nett gemacht, dass neue Twitter Widget. So kann man Tweets über ein Thema (z.B. Region, Lieblingsfußball-Club, eigene Tweets, ...) in seine Homepage einbinden.
Funktioniert leider nicht in blogger (möchte keinen link html tag), mal schauen ob ich später dazu komme es in die Vorlage/statische Seite einzubauen.

Außer Kontrolle - Welche Macht hat das Internet?

Gerade sehr gute Sendung auf Phoenix gesehen: Außer Kontrolle - Welche Macht hat das Internet?

Sehr sachlich, informativ und kompetente Gesprächspartner (u.a. Ossi Urch).

Wiederholung um 00h, und Morgen um 09:15 (Do, 25.06.09, 00.00 Uhr, Do, 25.06.09, 09.15 Uh) . Wer Zeit hat sollte es sich anschauen/aufnehmen, lohnt sich.

NVIDIA and KDE4 problems: SOLVED!

2009-06-24T21:00:00.003+02:00

KDE4 never really worked on my PC. It was slow, everything was slow, not only effects :-(

I have a NVIDIA 8600 GT, and I was used to compiz, which performed very nice with this grafic card.

I knew there were few possible source of problems:

KDE4
Qt
Nvidia driver

At the beginning of KDE4 (KDE4.0), many performance problems were mentioned with Nvidia drivers, so I didn't invest too much time, just updated KDE 4 with every new version, but it didn't get better. I also tried several Qt tweaks, but still no luck. Same for Nvidia: I downloaded and tested every new version, KDE3 was running very well, even if compiz, but KDE4 was still very very slow.

Few days ago, I found this following entry in openSUSE formens. It suggest to "activate" RenderAccel in sax2 configuration. I don't know if you have ever been in the sax2 driver configuration dialog, but here is what it looks like:

I've also been here a couple of times, but never realized that you can activate/deativate driver options here. "activate" means selections, deactivate means no selection. No very userfriendly and intuitive, I expected to have a checkbox or a true/false option panel or something like that.

However, now everything is fast and I'm enoying all nice desktop effects :-)

Few critics:

Why is RenderAccel not activated by default? @suse
Fix usability of SaX driver options dialog. @suse
I think kde4 should work well also without some features supported by grafikcards. I think RenderAccel is mostly for transparency effects.

Thanks to the upnp2mrtpg script I'm now monitoring my Fritzbox.

Also, I upgrade from mediawiki 1.11 to 1.14, and as usual, everything went smooth. It took 5 minutes including download, mysql update and first test. As I don't have any special adaptation (compared to other people I know) I had nothing to patch. I just checked that https is still working (was, because it's apache configuration and has nothing to do with mediawiki).
Finally I installed few more plugins I got used to: fckeditor, syntax highlighter. Still have to test file indexer.

Life

Wenn ich jemanden etwas "beibringen" möchte (von einer Idee überzeugen, Wissen weitergeben...), dann gehe ich erst mal davon aus, dass er alles selber verstehen kann, nur dass ihm vielleicht noch die notwendigen (Rand-)Informationen (Background) fehlen, um selber die Lösung zu erkennen (schön ist manchmal auch wenn es nicht so ist und einer interessant Diskussion entsteht). Meine Aufgabe ist es ihm diese Information zu liefern.

Und manchmal bin ich derjenige dem die Information fehlt um eine Lösung zu erkennen :-)

It's not my primary job, but during last weeks/months, I somehow was involved in database design/optimization/tuning, and it's one of the thing I like to do.

As with everything, I like to study the theoretical background to understand why things are how they are and build from them some basic rules which helps me to draw optimizations prototypes which I can then double check against real world models.

Aside all official database/oracle documentation (oracle OTN, asktom...), I like to get information from people dealing daily with problems. Blogs are one good source of information for this, so here is a list (in no particular order) of database oriendted blogs I read regulary:

Richard Foote's Oracle Blog,
Oracle Blog
Rittman Mead Consulting
About Oracle, Simplicity is the ultimate form of elegance and sophistication
Striving for optimal performance
An expert guide to oracle technology
The database column,
Oracle FAQ aggregator
The database programmer,
Oracle scratchpad
Oracle TEXT
Tom Kyte blog
Inside the Oracle optimizer, very technical
Structured data
OpenSource OLAP,
McLochlain Weblog,

Hope this helps someone.

Next to come: my own "Golden rules of indexing" about how to build an index.

Timezone Data Versions in the JRE Software

2009-04-27T13:53:00.002+02:00

From http://java.sun.com/javase/timezones/tzdata_versions.html:
"TZUT 1.3.14 now available containing the Olson 2009f update. Please contact your local SunServices Office to obtain this version. For questions, please contact Sun Support"

I called the local (German) Sun support, but they couldn't help me. All I got was an email address in UK. So I wrote them an email...waiting for a response.

Where do I get the tzupdater > 1.3.12? google didn't help me, neither anything mentioned in Java forums why they are no longer available from the page above.

Update 28.04.09:

the e-mail address I got from support was wrong, so no answer from Sun yet. I asked the session again directly on the feedback form on http://java.sun.com/javase/downloads/index.jsp#timezone
Also strange, IBM doesn't provide newer version than tzdata2008i for IBM JRE:
