Did you know that there are more than 40 synonyms for "crafty" in English language... We have so many words to describe people's trickiness. There must be a good reason for that.

All Globals are bad

All singletons are (for this purpose) Globals

It is possible to update Eclipse Indigo to the new Eclipse Juno while preserving your settings and (well, hopefully) everything else. Note that some plugins may not support the new Juno release yet, so consult your specific plugins release notes and updates to check this. Also make sure you make a backup of your Eclipse installation – just zip/tar the whole folder and if something goes wrong you should be able to just unzip/untar it back to its original location like nothing happened.

Add new sites to my "Available Software Sites" (Help -> Install New Software -> Available Software Sites)

http://download.eclipse.org/releases/juno

http://download.eclipse.org/tools/cdt/releases/juno

Then just initiate an update (help -> install updates).

After the update

BlackBerry is quickly loosing its market share. Besides that it is failing to innovate, which is actually mostly the reason it is loosing its once lion market share so fast to Android, iOS and even to Windows Phone 7. Let's check out how the OS distribution changed since January 2012. Here's the post about [link id='637' text='BlackBerry OS distribution in January 2012']

And here's the BlackBerry OS distribution in January 2012.

*

***Note: This is not an official information or official numbers. These is a sample from one of the apps that run on BlackBerry and  have enough users so that it is statistically significant.

It is interesting to see that there is almost no change (well, no surprise here there were not many changes/upgrades in the realm of BlackBerry). It is interesting to see though that the 7.0 OS's pie has slightly increased, surprisingly cutting the 5.0 OS's pie. Or maybe actually it is not at all surprising. The 5.0 people have upgraded to 7.0 devices while 6.0 people did not bother (or could not) upgrade their OS to 7.0.

Here are the charts side by side:

July 2012	January 2012

Let me know in the comments what you think!

To get a proper Unix epoch time on Android you should divide the current time by 1000 since Android will return the epoch in milliseconds

 
System.currentTimeMillis() / 1000

The method name also hints about this ;)

So the text.ClipboardManager is deprecated and you should be using the content.ClipboardManager instead, BUT not so fast. If you are still supporting devices pre API level 11 which is 3.0 aka Honeycomb (note that 3.1 and 3.2 are API level 12 and API level 13 respectively) then you can't obviously use the content.ClipboardManager as it will fail on devices pre Honeycomb.

ClipBoardManager docs

 git rev-list -n 1 HEAD -- <file_path> 

Which will give you the commit hash and then

 git checkout <deleting_commit>^ -- <file_path> 

Or you can do it in one command using a variable for the filepath

Assuming you are using bash, setup an environment var:

 export gitfile=<file_path> and then 

 git checkout $(git rev-list -n 1 HEAD -- "$gitfile")^ -- "$gitfile" 

You can use

 echo $gitfile 

To make sure that the variable was set correctly.

For other shells you would use it's own mechanism like

 setenv 

etc...

Hope this helps!

To ease life of the Android developers who use action bar and tackle the problem of fragmentation between the older devices and the newer devices the following library might be very useful:

github.com/JakeWharton/ActionBarSherlock

The library will automatically use the native ActionBar implementation on Android 4.0 or later. For previous versions which do not include ActionBar, a custom action bar implementation based on the sources of Ice Cream Sandwich will automatically be wrapped around the layout. This allows you to easily develop an application with an action bar for every version of Android from 2.x and up.

P.S. The official Github Android client uses this library.

2015-03-07 UPDATE: Google has released an actionbar component in their compatibility library a while ago. You should be using this now.

If you were in need of Git hosting and you did not like Github for some reason (I am personally not that crazy about them). You can get free Git hosting at Bitbucket. Not only they give you a free hosting of personal repositories but they also provide a nice wiki and a bug tracking. These are the same guys who develop Jira – a widely used bug tracking system. Although the bug tracking that you get with BitBucket repository is pretty basic, it is enough for most small to medium projects.

But the goodies do not stop here. They offer unlimited accounts for educational purposes and otherwise very reasonably priced accounts.

Oh and actually they offer both HG (Mercurial) or Git hosting through the same interface/website/account :)

Check them out!
