Drop down terminals

I like drop down terminals. They're something I can't live without. Since a lot of time I had been using the Gnome shell extension https://extensions.gnome.org/extension/442/drop-down-terminal/ but Gnome shell extensions, though great and light weight, are a bit unreliable at this time. They cause trouble almost always after every distribution upgrade, Firefox upgrade or gnome shell upgrade. Its all the more troublesome since Firefox shifted to rapid updates.

A good alternative is Guake. Gives a lot of customization, and does what it says. But I don't want any customization. I want just a simple, fast, reliable terminal whose sole purpose is to drop down when commanded to. So, I've stripped Guake of all the customization. Lets see how long it says loyal.

MEB: Taking Incremental Backup using last successful backup

Published another post on MySQL Enterprise Backup at Oracle blogs today.

A new prefix 'history:' has been introduced for the –incremental-base option and currently the only permissible value is the string "last_backup". So using the new option an incremental backup can be taken with the following command:
$ mysqlbackup --incremental --incremental-backup-dir=/media/mysqlbackup-repo/ --incremental-base=history:last_backup backup

Google calendar quick add

Often in Google Calendar, quick add can prove to be very helpful and more importantly - fast. With intelligent keyword and context matching it'll make things faster when we're to add a bulk of events spread over a range of dates. The best part comes with recurring events - we dont' have to click on 'edit event details', check the 'repeats' check box and select how the event repeats! With 'quick add' we can simply schedule a repeating event as:

Birthday Manu 7 May repeats yearly

 or

have medicine 9pm repeat daily for 2 weeks

Google calendar will intelligently parse the above comments and schedule the event/reminders accordingly.
A list of possible 'quick adds' can be found here:
http://www.google.com/support/calendar/bin/answer.py?hl=en&answer=36604

Quick add can also be seamlessly integrated into your application using the calendar API. Instructions can be found here:

~ Happy holidays, and have a great time scheduling..

Private sidewiki?

I was wondering if there's something like a private 'google sidewiki' in which the entries are not actually published but are synced with your account and the notes/anecdotes are shown the next time 'you' visit that page. Some Firefox/Chrome plugins do give that support but the problem is localization of your information. All your notes etc. on webpages are visible only on the browser and not available elsewhere.

C:/Windows/Installer directory overflowing bug?

DISCLAIMER: I accept no liability for the content of this post, or for the consequences of any actions taken on the basis of the information provided. Use this solution at your own risk. This is a solution which worked on my system and may / may not work on others.

Hi all. Recently was bugged by the problem of my C: getting used up erratically. Everyday i'd remove some application and free space and lo! Next morning again <20MB space left on this drive.
I used the following tool to figure out the problem:
Free Disk Analyzer from http://www.extensoft.com/
Saw that the folder C:/Windows/Installer took up almost 80% of the space!

Initially thought of deleting several files at random but then read in forums that this approach is definitely not advisable. In many forums I was redirected to this page: http://support.microsoft.com/default.aspx?scid=kb;en-us;290301 but as it says, they've removed the installer from here.  This utility, however, can still be download from http://majorgeeks.com/Windows_Installer_CleanUp_Utility_d4459.html. INSTALL IT. Do not go and run this utility from its GUI since it doesn't give the option of removing only 'orphaned' installer packages - which is what we want to do. So, fire your command prompt, cd to C:\Program Files\Windows Installer Clean Up and run : msizap g!


PS: Cleaned up 16GB of space in 10 sec!

     else:  
       return [array[1],array[0]]  
   else:  
     return merge(merge_sort(array[0:int(len(array)/2)]),merge_sort(array[int(len(array)/2):len(array)]))  
 def merge(array1,array2):  
   p1=0

Importing H2 database in RapidMiner 5

Hi! Here's the configuration to import your H2 database in Rapidminer:

1. Add the H2 driver to RapidMiner: Go to 'Manage Database Drivres' and configure it is follows: (The Jar file lies in the /bin folder of your H2 installation; give its path). Save these settings
   
   
   
   
   
   
   
   
   
   
   
2. Now go to your process window in RapidMiner and drag the 'ReadDatabase' operator:

3. Click on it and add attribute values as shown in the image:
(database url is the complete url of your embedded database file). The default username in H2 is 'sa' without password. But, this won't work for RapidMiner since its mandatory to give some password. So, Create a new user with some password using the 'CREATE USER' sql command. In my case, I created a new database user called 'user1'.

4. Once this is done, restart RapidMiner for changes to take place. Do not forget to save your process when RapidMiner prompts you to.

5. Now, Click on Build SQL Query. You'll see something like what is shown on left. Select the table you want to read (just click on the name of the table and the select * query will be generated) and click OK

Google Says There Are Now 30,000 Apps In Android Market

Google Says There Are Now 30,000 Apps In Android Market: "

At the most recent Mobile World Congress, Google CEO Eric Schmidt revealed that the company's partners are now selling over 60,000 Android handsets on a daily basis. With that kind of growth rate, it's no wonder that the size of the Android Market is increasing in its slipstream.

While Google doesn't publicly show how many apps there are in Android Market, a Google rep this morning informed me that the store now serves approx. 30,000 apps in total.

The holy grail for hackers from across the country, Binary Pirates has just one rule- THERE ARE NO RULES. Do whatever it takes to capture the 'flag' and move to the next level. The event will test your understanding of networking principles and web technologies and your ability to bend them to suit your needs. In short, this event will shake the very foundations of your hacking knowledge and your ingenuity.

Geek 'N Latin

Confound 'Em.

Sick of those cascading tabs and well-behaved braces? It's time you break the shackles and let loose the spaghetti coder inside! With creativity and a taste for technical insanity being the only pre-requisites, arm yourself to take on your twisted binary counterparts in the arena to obfuscate, brain-fuck, reverse engineer and whirl your way to victory.

RIP OPEN

Online Round 1 of Rip Open will start on 10th January, 2010 at 00:01 hrs and will end on 12th January, 2010 at 23:59 hrs

Open source development as you never thought existed. This event is for those who believe in the power of the open source. This event is all about the constantly evolving world of open source where people with innovative ideas get together, share their resources and bring out totally new creations using resources someone else created before them.

Terminator 1.0

Have you ever wondered how codes work behind the scenes from the machine level? If your answer is YES, then register for this event ! You will surely enjoy and learn.

Terminator 1.0 is an assembly language coding competition. Higher level languages are very prominent in popular coding competitions but unlike them, this event explores the limitless possibilities in assembly language coding and brings the participants closer to what happens behind the scenes! The advantage of assembly language is that the participants do not have to remember any syntax as there are limited commands and statements. All that matters is their logic and reasoning power.

Code JAM

A technical festival without a coding competition sounds incomplete. Doesn't it!
So here is a chance for everyone to brush up their minds for a challenging programming contest with the freedom of coding in whatever language they want.

Quark 2010

Assembly Language Coding Event !!

Terminator 1.0

At Quark 2010, we are organizing a unique event in which coders have to compete in simple assembly language !! Its a fun event testing your skill in basics of assembly language!
