New toy: DSO-QUAD

I got one of these chinese miniature digital scopes, and I can say that yes, it is an interesting tool, but more useful when you have to use it on the field. The user interface is good, but the lack of the traditional knobs is sad. Luckily, it is completely open source. Anyway, I hope someone (or myself) build a control and visualizer tool over USB. That will make it much easier and practical to use on a workbench. Ah, for audio signals it seem to be accurate and good.

Batch converting word files to PDF

Today I had to convert hundreds of .doc files to .pdf. I first thought it would be impossible because there would be not such option or command line option on MS-Word. But surprisingly, this great tutorial shows how using powerful command line arguments for MS-Word.

From the page above (with a little change):

FOR /F “usebackq delims=” %%g IN (`dir /b “*.doc”`) DO “C:\Program Files\Microsoft Office\OFFICE12\WINWORD.EXE” “%%g” /q /n
/mFilePrintDefault /mFileExit && TASKKILL /f /im winword.exe

this batch will get all the doc files on a directory and convert them to PDF by using the default printer, which is configured to print to PDF files.

Google chrome strange behavior

I simply did not know what to do anymore trying to get Google Chrome working on Ubuntu 12.04. I tried many things and finally found that the problem was an incompatibility with the video card of my Sony Vaio!

The solution was simple:

$ google-chrome –blacklist-accelerated-compositing

Then I edited “/usr/bin/google-chrome” and added this argument 🙂

1. Question assumptions;
2. When in doubt, improvise;
3. When your path is blocked, pivot;
4. Practice, practice, practice.

By the way, the at Ted talk (link above) is great. He also talks about the Telegarden project. Many related works can be found on the book “Beyond webcams” – a great one to read.
