### Weird Thunderbird Bug

Since I upgraded my Thunderbird to version 9 if could no longer paste tables from OpenOffice.org Calc to Thunderbird as a table... they always get inserted as graphics.
Paste-without-format would just copy the plain text, but - of course - no format.
The problem has also been reported with Microsoft Office and LibreOffice.

I did not really notice the first couple of times, until co-workers started to complain that they no longer could copy/paste elements from my "tables" because they were images.

Did some searching on the web and found the bug ... indeed introduced in TB9 supposed to be fixed in FB10 (have to test this on a vbox):

The actual problem is when Thunderbird parses the meta-data of the clipboard, it does a locale-specific parse of a decimal number (the version)... but the version string will always contain a dot (.) and never a comma (,), since it is not really a decimal number. So there is a difference between e.g. German and English system(!) locale, i.e. the problem will appear on German windows, but not on English windows.

Changing the decimal symbol to a dot (.) in the Windows system settings will actually "fix" (circumvent) this problem. I just tested this.
Not sure, which system-wide setting I should keep now...

As I noticed in the bug, the fix is to treat the version as a string, not a (decimal) number.... That's better.

### Favorite Equation

This is not really IT related, but geeky enough, I guess.

The other day I read a post or article about job interviews in the tech sector, like Google et al... And - so the article went - Google (if I recall correctly) once asked a candidate what his favorite (mathematical) equation was.

So here are my favorite equation(s) - not a surprising choice, given that my background is electrical engineering.

This one keeps fascinating me since I first heard it in an early math lecture at TechU Vienna. It goes like this

(or rather substitute a j for the i... as I said - electrical engineering :) )

Well, it contains 5 elementary constants/numbers  (0, 1, e, π, j) and it contains the 3 basic arithmetic operations (addition, multiplication, exponentiation)... more on Wikipedia.

No surprise here for an electrical engineer, again, right ?

I'll show the most simple (and differential) form here, since I think this shows their beauty best:

$\nabla \cdot \mathbf{E} = 0$
$\nabla \cdot \mathbf{B} = 0$
$\nabla \times \mathbf{E} = - \frac{\partial\mathbf{B}} {\partial t}$
$\nabla \times \mathbf{B} = \ \ \mu_0\varepsilon_0 \frac{\partial \mathbf{E}} {\partial t}.$
For an explanation and the more general form, check out Wikipedia.

And why those?
Well I think the symmetry is apparent. And they are so fundamental to basically everything

Also, according to Wikipedia, I'm not really alone with that choice:
A poll of readers conducted by The Mathematical Intelligencer magazine named Euler's Identity as the "most beautiful theorem in mathematics". Another poll of readers that was conducted by Physics World magazine, in 2004, chose Euler's Identity tied with Maxwell's equations (of electromagnetism) as the "greatest equation ever".

So... rather mainstream, right? Would not get me a job at Google :)

### Evernote Clearly

A new tool to read article-like web pages (blogs, news, ... ) without the noise.
Evernote Clearly
Our newest browser extension for Chrome and Firefox makes a beautiful, distraction-free reading experience on the web with just one click.

In the past I used to achieve this, by saving those articles to ReadItLater and the read them (without noise) on my iPad. With Evernote Clearly I can do so immediately in my browser...

And this is, how this post looks in cleary... leaner.. more easy to read.

Available for Firefox and Chrome.
