This is a long pending “to do item” of mine.  Having a blog is a good way to keep notes of what i have learned. I plan to read each and every computer science graduate course from MIT and write notes about what I have understood. May be even about my own ramblings of the course. Hopefully I gain additional knowledge. It may not be perfect. But I am hoping that It does help me in reviewing my material later. I prefer reading than actually watching videos.  I will read as much as possible and post summary here. Hopefully it is helpful to me and others.

I myself being an Indian developer is ashamed to say that not many of us write open source software  ( myself included  ) .  To  be brutally honest with myself and rest of you, I think I lack personal focus,  I am trying my best to fight with it and build something great. Hopefully everything turns out well.  Trovalds nailed it here.

Unless we have something on our own , something that is unique to India we will all be serving the west ( Europe and USA ) .  I think this should change for our country’s benefit. Let me build knowledge when I am in US and then later go back to India and work on what I am most passionate about.  Life in USA has taught me humility, taught me that I am quite a useless guy  – I will learn good things from here and take it back to my country. I like the fact that people here are very disciplined and organized in work, polite and considerate in public places.   Nevertheless ,  I am really sad here – My family is back in India and I really like it back home.  Hopefully when I am done with my doctorate in Computer Science- I might get to do what I truly love. I must practice discipline, restraint ( talking, spending, activities , eating … )   and focus.

This post is less on software engineering but more on my false sense of self worth at times.

I came to know about ascii doc recently , just edit your document in plain text files and publish it to multiple formats . Since ascii is plain text file , you can even use a normal text editor store it and the document remains largely readable 🙂 .   Ascii doc FTW ! .

I am thinking of creating an e-learning website almost completely in ascii doc.

Basic Application elements

•    Views  – TextBox etc ,
•    GroupViews – LinerLayout etc
•    Activity   – Main Screen and other screens
•   Intent  – Communication mechanism between Activities

Android Activity Life Cycle ( Names are kind of self explanatory ! )

•  OnCreate
•  OnStart
• OnResume
• OnPause
• OnPause
• OnStop
• OnDestroy

findViewById(R.id.response)  :- find the view by id in xml file , Cast it to appropriate class

Toast for displaying small messages

startActivity(intent) to create an new intent

Layouts

• Relative
• Absolute
• Lenier
• Table
• Grid

Log.* for logging  (DDMS)

Its is actually very easy , Most of it it there in SDK documentation.   I will read the SDK doc to get stuff done for the most part .  Bye for now . This is not supposed to make sense for anyone other than myself gg 😀

Borrowed from Stackoverflow . Keeping it here for my ready reference

First, check the kind of quotes you are using in your udev rules. It looks like you might be using non-ASCII double quotes. See the difference between the quotes around usb and usb_device, etc.

UBSYSTEM=="usb", SYSFS{idVendor}=="1bbb", MODE="0666"
SUBSYSTEM==”usb_device”, SYSFS{idVendor}==”1bbb”, MODE="0666"

You can also just use sudo with ADB, as suggested by @JeremyD. Doing that makes this file essentially irrelevant.

Second,

1. Edit ~/.android/adb_usb.ini (or if you are running as root, check /root/.android)
2. Add 0x1bbb to the end of the file if it already exists, otherwise do: echo 0x1bbb >> adb_usb.ini
3. adb kill-server
4. adb start-server
5. Check output of adb devices for your device
