Quick Calc on Mac

Click on Apps icon - Select calculator Or open spotlight, type calculator and select the first option to launch calculator. Type in your numbers and operators to get the result, seems to be the most used one. You can also use Dashboard (by pressing F4) and calculator should be there by default.BUt the easiest of them if your data isn't very complex is just open spotlight (cmd-space) and type in your data there... For e.g., 3^4*2 and the first result is your answer. :)

Android/Java Static Code Analysis Tools

Java/Android compilers in itself are very good and give very good warnings to inform about various issues/things done wrong.

Just thought about trying free Static Code Analysis Tools and found the below:

FindBugsPMD All have eclipse plugin urls, so you can add the URLs at the software site link and easily add the plugins.
FindBugs Damn good tool. Install the plugin and then right click on a java/android project. You will find FindBugs Menu. Just click on FindBugs and it gives a very good overview of the review bugs in it's own perspective.
Each of the bugs is categorized by the pattern (you can change the categorization in the toolbar) and it lists all the occurrence of that type in all files in the project under that.  Clicking on it, it gives a very very good description about what the error is and why that is considered to be an error. It indicates if its just a suggestion or performance issue or style issue.  Some of these were quite new for me and the explanation made me feel …

Kaiwara and Avani Trip

Image
Date: 21st November
Places Covered: Kaiwara, Kailasagiri, Kurudumale, Mulbagal and Avani.
Vehicle: My Ritz
Distance Covered: 280 Kms
Start from Home @ 8 AM
Back Home @ 10 PM


We went to Kaiwara to see the Amaranarayanaswamy temple there. 
A passer-by suggested us to visit Kailasagiri when we asked for directions to cave temples of Kaiwara. Didn't know it was man-made caves but it was first time I saw chaturlinga (4 faced Lingas like Brahma). Nice place to visit and temple free lunch was amazing. Details about this place: http://www.deccanherald.com/content/6954/snippets.html


We came back to see Kaiwara caves with the lakshminarasimha temple in the caves and then saw the "Kaiwara" Thatha's Ashram + temple.




We then headed to Kudurumale Ganesha temple near mulbagal. There is a large stone idol of Ganesha.


After that we went to Anjenaya temple in Mulbagal town. It was supposed to be very famous but didn't find much crowd and the pujari there wasn't interested in doing a poo…

Mac - dvd drive not visible in Finder

Image
In MAC, the dvd drive gets listed in finder only if a dvd is present. Else it's hidden.
In some rare cases, even after you inserted a drive, the disk might not be visible in finder and since there is no eject hardware button near the DVD, there doesn't seem to be a way for removing the disk.

Browsing around, found the following ways (from multiple sources) to eject the disk and re-insert it:

Force restart finder.Open disk utilities (Applications/Utilities/DiskUtility) and the drive should be available there. Right click on it and select eject.Command line always rocks. Run the following in a terminal: drutil tray eject Cross posted from: 
http://techieconnect.blogspot.com/2011/11/mac-dvd-not-visible-in-finder.html

Open Terminal window here - Mac OS X

It isn't as easy as updating registry key in windows (or atleast I don't know). Found this link to be good source for app to do that.

https://sites.google.com/site/michaelsafyan/software-engineering/open-in-terminal
Chose the one with customized terminal window icon.
If the folder Finder doesn't exist in your 'Application Support' directory, then do create it.

If you have any other easy ways of doing this, let me know.

Innovating at Intuit - SnapTax

Check out the video.. especially the part between 1:16 and 1:21 :)

Sireesha 1st Year Birthday Celebrations

Sireesha 1st Year Birthday invite

Created a simple tiny Android app





Started at around 11 PM and completed around 5 AM.

Weave - a new iPhone app from Intuit

Intuit has just released a product called weave for ios platforms called Weave (Nothing to do with Firefox sync app - weave).

http://weave.intuit.com/weave/

Weave will ensure that you never forget a todo. Quickly enter todos wherever you are and get alerts when you have an upcoming todo.



Good things I found:
1. Nice UI
2. Has a good first use experience. Kind of demo mode with the help links showing how to proceed to the next step. Hovers over the screen and helps in clicking around.
3. Does many things :). Has money in - money out too.
4. No Android app - opportunity for us to create a better one? :)

Bad:
1. requires a login before start
2. red theme - different from Intuit blue.
3. Projects - might not be so common word for general users and doesn't gel with the Todo's being created.
4. Does too many things :). Differs from Apple mantra - Do one thing and do it well. Money in - money out could have been a separate product.
5. No Android app

"Check your UID Status" Link

https://portal.uidai.gov.in/uidwebportal/enrolmentStatusGet.do
Giving my details keeps returning 'NOT FOUND' though :(

Applied for UID

Applied for my UID along with Colleagues - Prashant and Saneesh.

Good: The enrollers were very professional and courteous. For a one letter spelling mistake, they re-did the enrollment completely again. Know other govt agencies where even with 100s of mistakes, they say it's fine and don't bother changing anything.

Not so good Experience: The entry part of demographics was time consuming. Retyping so much data in Kannada again was not expected (mainly for word changes like 2nd Cross to 2ne adda rasthe.. etc). The client/webapp kept showing error on demographics screen though all data was filled. The advice from a senior person there : Keep pressing "Finish" and it will take it. :)

./adb -s logcat -v raw

Unknown error on eclipse android console

Not sure what the below means:
local emulator[343] : kCGErrorIllegalArgument: CGSGetDisplayBounds (display 2b3c4d11)

Googling doesn't return any worthwhile links too.

Eclipse: Removing Todo: Auto-Generated comments

When you use Eclipse menus to create new class, constructor, method or even add a try/catch, typically it not only generates the functionality but also adds a TODO. This is good to indicate that the comment has to be replaced with a proper functionality.

However in a team environment, it's not easy to make people delete the line and add the code. Task remains and it becomes difficult to delete it at the end.

To remove the auto addition of that comment line, you have to follow the below steps:
Goto Window -> Preferences -> Java -> Code Style -> Code Templates
Click on Method Body.
Click Edit.
Remove the commented line. (Something like: // ${todo} Auto-generated method stub)
Click Apply.
Repeat the steps for other elements.

Click save.

Warning on app launch in emulator in MAC

Every time I try to launch my android app on emulator, i get the below warning:
Warning once: This application, or a library it uses, is using NSQuickDrawView, which has been deprecated. Apps should cease use of QuickDraw and move to Quartz.

Looks like this can be safely ignored as it's the problem with the emulator using deprecated api. Link: http://groups.google.com/group/android-developers/browse_thread/thread/f10995f2a829229d

Deleting user database

DBOpenHelper or SQLiteDatabase doesn't have functions to delete the database. Looks like there are people who are using file delete by going to the database location and deleting the file programmatically. The easier solution is : Android does provide the mechanism to delete the file. It's available in ApplicationContext though.

You would do something like this:

InstantReturn app = (InstantReturn) getApplicationContext();
// dbHelperInstance.close(); // dbInstance.close();
if (app.deleteDatabase(DatabaseOpenHelper.DB_NAME)) { Log.d(ViewConstant.APPLICATION_NAME, "deleteDatabase(): database deleted."); } else { Log.d(ViewConstant.APPLICATION_NAME, "deleteDatabase(): database NOT deleted."); }

Open javadoc in external browser - Eclipse

Should we do this for each workspace?

Function key on aluminium keyboards - MAC

Seen that many people do not find the Fn key in the new aluminium keyboard for mac and end up setting "use default functionality of function keys" in system preferences. However this affects the laptop keys too and might not be preferred by all.

Solution: There IS a function key in the keyboard. Not in the place we expect it though. Look for the key under F13. :-)

Opening multiple instances of Eclipse on mac.

Double clicking on eclipse icon always opens the same instance on MAC. To solve this, you can open terminal (Command-Space to launch spotlight. Type in terminal and click on the top hit/Terminal link).
Cd to the place where you unzipped eclipse.
For .e.g, Eclipse/Eclipse.app/Contents/MacOS/


Then run eclipse &. (& makes sure you run eclipse in background, so that you can kill the terminal window.).

WebView loading external browser

If your webview loads external browser and doesn't display the contents inside the webview, do check if the page is doing any redirects. Redirects are by default launched in external browser.

Keyboard shortcuts for emulator

run emulator in tools directory of android sdk with param -help-keys. This lists the keyboard shortcuts understood by the emulator in your platform. For windows, the shortcuts displayed will be different than for mac.
