Kindle 2 isn’t a device for me – Amazon doesn’t convert math text

Some days ago, I received a Kindle 2. The device looked good and buttons and controls felt just fine.

Actually, I returned it today, since Amazon’s PDF conversion service is by no means able to convert more than trivial text.

Here is part of my input PDF, which I created using LaTeX:

Upgraded to WP 2.9 – and ended up with an HTTP error 500

After quite some time, I visited this my blog to apply the most recent Wordpress upgrade, the 2.9 release.

After the I finished the upgrade, the front-end rendered fine, while I constantly got an error from with ADMIN site: HTTP 500 error.

In case your site runs on a server hosted by 1&1 too, you have to do two things to get ADMIN running again:

1. Create a php.ini in WP’s root directoy and add this single line of text:

memory=20MB

2. Edit WP’s .htaccess file  and add

AddType x-mapp-php5 .php

as the very first line.

Rumsfeld’s Knowns and Unknowns

Donal Rumsfeld, US Secretary of Defense, 12 Feb. 2002, Department of Defense News Briefing:

As we know, there are known knowns. There are things we know we know.
We also know there are known unknowns. That is to say we know there are some things we do not know.
But there are also unknown unknowns, the ones we don’t know we don’t know.

Related to RIAs? No, not a bit! But strongly related to the current credit crunch or investment banking in general.

Satyajit Das’ beautifully explains the concepts of known knowns, known unknowns, unknown knowns and unknown unknowns in his great book Traders Guns & Money. For anybody, who aims to know the history and evolution of investment banking, Das’ book is a must.

Missing german locales in FlexBuilder’s SDKs? Here is how to generate them

If you try to localize a flex application with e.g. en_US and de_DE locales, FlexBuilder will likely complain about a missing german framework resource:

unable to open ‘/Applications/Adobe Flex Builder 3 Plug-in/sdks/3.2./…’

No need to give up, make the resource yourself:

- Open the SDK’s root folder. On a Mac, it is likely to be here:

/Applications/Adobe Flex Builder 3 Plug-in/skds/3.2

- Execute this command

./bin/copylocale en_US de_DE

Now recompile – probably clean it before – your project your Flex project. Everything should look fine.

If FlexBuilder complains about ‘Error creating AIR file: 305: ERROR, 10′ – Solution

Today, I worked on Activity, an AIR-based time tracking solution:


As I read of Flex SDK 3.2.0 and AIR 1.5, I decided to upgrade. While the update install itself finished fine – FlexBuilder failed to run the compiled app. Actually, FlexBuild printed this error message:

Error creating AIR file: 305: ERROR, 10, http://ns.adobe.com/air/application/1.1

If you see such an error message, open the application’s descriptor file -app.xml and review the second line, which should contain an XML namespace declaration like

http://ns.adobe.com/air/application/1.1

Change the postfix version number to 1.5

http://ns.adobe.com/air/application/1.5

and you are fine: The compiler just needs to know which lib to compile against.

Update 2009-02-03: Our fellow Flex-coders in Russia picked up the post.

Microsoft promotes Flash

Recently, Microsoft kicked off the movie service ‘msn Movies’ in Germany. While ‘msn Movies’ is free of charge for customers, Microsoft refinances the offering by spliced-in advertisement. Some are quite popular movies like ‘Good Will Hunting’.

As I read about this offering, I expected a Silverlight proof of concept. Actually, it is not:‘msn Movies’ is a service fully based on Adobe Flash technology. You guess, why ;-)

To review Microsoft’s Flash offering, have a look here.
