Cool tricks you can try on Google

Those are really cool and interesting tricks you can try on the Google Search Engine, at least for me, these next ones are most useful:

1. calculate tip!
  tool to calculate the fees and tip per person.

2. Books by author name
  easily you do a search about the books of your favorite author

3. Songs by singer name
  I did not try it but I assume it will work as the previous one.

4. 100 usd to "currency name"
    really cool!, there are a lot of currency

5. city to city distance
   try it, it is really cool, unfortunately it did not work on some cities I tried.

there are more of them, you may try them here

Cool, see you

ogv to mp4 without codec

This is a great trick, in fact yesterday it saved my life, I had an ogv file generated by gtk-recordmydesktop and I need to convert it to a mp4 file because the user do es not use GNU/Linux, so here it is the command line:

ffmpeg -i firstfile.ogv libx264 -vpre medium -crf 24 -threads 0 -acodec copy secondfile.mp4

As you can see we don't use any codec to export the format and this is really great - and faster- in order to get your file.

I read some howtos using codec such as libfaac but honestly it is not as quick as I need it, the result file was ok, I did not loose video quality and the audio was like the source one.

hope to help

enabling debug mode on your android phone

This is a really cool trick, I am developing an android app, the deadline is this next friday -hope can make it!- and tonight I start with the first checklist of test, so I got a bug but I could not see it from LogCat, that is really weird so I thought it was an isolated thing, I decided to try it again and still the same, but this time I read something on the LogCat window:

"Unable to open to open log device '/dev/log/main' no such file or directory"

So I discovered this bug occurs when the Android device turn this off. Googling about this would be some kind of complicated because there are many approaches, so I will show how I fix it, but remember, it is not sure it may work on your Android device:

0. My device is not rooted, it is a Huawei brand
1. dial this number on it:

*#*#2846579#*#*

 2. inmediately it will show a menu with 2 options: MMITest_II and ProjectMenu

3. Choose ProjectMenu

4. then Background Settings

5. Log Settings

6. in Log Switch choose "LOG on"

7. in Log level Setting choose "VERBOSE"

8. reboot your device

 

that's it, next time when you run your android app you will get all error messages from your device on the LogCat Window.

 

really cool ah!
