Basic understandings of Android Intents and starting activity from it.. .................................................................................................................... Toast and its simplest work to show the text: Toast.maketext(getActivity(),textview.getText().toString(),Toast.LENGTH_SHORT).show(); Starting Activity: >startActivity(i); //if i is a defined Intent object already; >startActivity(new Intent("name of the class from manifest.xml"); >startActivity(new Intent(this, "name of the java class"); Intents in Android and its invocations  1>Intent i = new Intent(android.content.Intent.ACTION_VIEW,Uri.parse("http://website")); startActivity(i); 2> Intent i = new Intent(android.content.Intent.ACTION_VIEW); i.setData(Uri.parse("http://website")); startActivity(i); **************** Uri.parse can take values as such to be shown: Like :> geo---for map application or activity; tel---...

Algorithms is the mother of computing science(If Mathematics is the father!!). The very first concept of computing was the algorithm on which depended the first simple operations and all that followed.              Yes, it was algorithms which preceded all the fancy big and small systems and electronics that has enabled us to visualize  all the fascinating results it yields according to it.  Derived from the name of Al Khwarizmi, the great mathematician who invented algebra, it lays down the basic step of realizing the solution to any problem being dealt. One great thing about it is that it involves all the mathematical details of the problem and gives a worthy information about its speed and space complexity. And hence, it provides a summative look on how the problem is going to be solved and all its estimates for the operation. A great thing one might want to know is that " Good algorithms are better than  Supercom...

It so happened to me this month that I broke the final barrier of not being a rated member of Codechef and Codeforces.  It has been a bit of time since I registered at both the reputed online programming platforms. Though I have been practicing some problems, still it didn't occur to me to make it a point when it came to the contests on this two sites- The coveted Long and Short contest of Codechef and regular contest for Codeforces. About how I did....Nothing so extra ordinary because all it needed was just one thought and determination that "I had to do it this time..at all cost". It paid off and now I am rated in both the platforms. Its a small step yet it is a big leap because it makes me motivated in all that I do now and  yes, I can say that I am more confident now than I was and this will help me in doing better. If there is anyone still not being a part of these things, I sincerely invite you to it. Not just that we can improve our skills but that it makes u...

Advent of Machine Learning  Artificial Intelligence has been used extensively in many applications over the last 3 decades. Areas of prime importance such as manufacturing, research, healthcare,finances and banking has been using AI on an extensive and intensive basis.      Over the recent years, researches has been conducted on the sidelines of AI to make its application much more productive. Things such as Data Mining popped up following the internet explosion and took a very pleasing growth proving its use in industrial scale applications.      One question has though  been asked since its inception:"Whether the machine themselves can be made to learn on its own?". This lead the researchers to conceive the idea of "Machine Learning",where the machine itself will learn from its own experience and derive appropriate action for a thing in future based on this, without having to write any program necessarily for the same. This almost...

Sometimes we get a buggy thing happening with us when most of our USB slots are filled up and we try to open a disk-drive by double clicking and we can't open except using  right-click options.  Well, many post and many suggestions go for checking the virus-stuff in the USB drive providing links to many third party tools and other anti-virus options. On the contrary of all these superficial tweets....I found my problem solved through a simple handling with the computer management tool for disk management. Before jumping on to the steps for solving the problem, I would like to highlight that the main cause for this problem is due to external disk(s) connected with the system bus. Each disk drive is allotted a unique letter from C - Z. Sometimes due to multiple connection, there may perhaps be a collison for the names and the system cannot recognize them. So,it does not allow it to be open through d-clicking! How to solve it.. You must be logged on as an administrator ...

According to TIOBE index Scala stands at 34th position with 0.290% rating.However, it has wide and good applications built on it( The list though does not account for anything related to the quality of the languages listed..its just based on popularity).   I read about Scala and was amazed to find out its varied and robust applications,,which is used in many popular applications of today).   Some of the many are listed here:      1>Twitter. .this describes the best .   ....Also Twitter uses Scala very robustly(as I learnt from this blog  as of 2008). May be it has changed now.   2>LinkedIn.. this link describes the best .   3>Novell .. See this link   4>Foursquare... Know more from here .   ......Foursquare is said to be built almost 100% using Scala(See this Quora link ).   5>UBS..and HSBC bank.      Having said all these,,I will also like to add that Scala has two web frameworks dev...

Its easy.., but sometimes it is troublesome with the installation of lxml module of Django. Here is the simplified steps to do it: Step 1>Download easy installer from this link -(Ok!, if you have already),  the "setuptools-0.6c11.win32-py2.6.exe" file. or search-> easy installer for python. Step 2>Download lxml.egg from this link Step 3> To install,just type the following: easy_install lxml.egg(this should be at the command window at the directory where lxml.egg lies->you can open command window by holding the shift key and then clicking on the right mouse button and then choosing from the context menu). The easiest method: download lxml.exe from here and simply install it your way..!!

The python software pip is a replacement for *easy_install*  .One may say it as a wrapper for easy_install, and indeed it is. It is used mainly to provide installation for python packages. First method: Step 1>Download the last easy installer for Windows that fits your installed python version: (download the .exe at the bottom of http://pypi.python.org/pypi/setuptools ). Install it. Step 2> Add c:\Python2x\Scripts to the Windows path (replace Python2x with the correct directory) Step 3> Open a new (!) DOS prompt. From there run easy_install pip For the 64 bit operating system refer to this link Second method: Step 1> Download the last pip version from here :        Step 2> Uncompress it Step 3> Download the last easy installer for Windows: (download the .exe at the part of   http://pypi.python.org/pypi/setuptools ). You can install it directly. Step 4>G o to the uncompressed pip directory from the command prompt and typ...

  Well it may be absurd for someone who is not so used to with all the command line stuff that one has to undergo, but for the geeks, its the things that keeps using computing enjoyable and something Geekyy!!   Some people really do not know and may be perhaps do not care for the command line interface commands.   That's why I have wriiten this piece of information for all those who wanna keep the geeky thing up in themselves             1> To move to the next directory we use      cd:\Destination_folder 2> To move to long  destination you can also type:      cd:\folder1\folder2\......\folder-n 3> To get into a diferent folder at the same root level      eg: pics and movs at c:\de\film      and you are at        c:\de\film\mov  and you want to navigate to pics    then type:       cd../pics 4> To move ...

Django is one of the most commonly used frameworks for web development today. It can be used in multi functional large scale database driven web application. Though it was created mainly for the means of rapid development of web application, it has well proven on its account for reliability and scalability. So here I am going to share some of my experience during the set up process which many of us find awkward. Hope this simplified version makes it easy for you all. Download:                 Download Django from www.djangoproject.com(get the latest and fail not to check out          which version of python it supports)                 Download Python- and this should be the one supported by the version which you     downloaded         Installation:   >Install python in your  machine   >Extract ...

W e humans,are the weakest and I would also say the wicked form of species of this great planet... Filled with greed and everlasting hunger for selfish gains. One thing I would like to share of what I have experienced  conversely is that there is also plenty of love around. May be that's why we still have families around. Surely without love being inherited , we would not have known how to give it to others.  And that is why we know love and how to give love. Though people term it as emotion, it is love and its commonness amongst all of us that make us able to thrive together. Now, I had begun this post writing about greed and arguably decried the general conscience of our human mentality pointing towards greed. And yes this is true! we have love in all of us, yet greed seems to overtake our mindset as we continually try to adjust to the current economic scenario. Recessions, job losses, rising food prices and all that modern corporate fallouts have indeed succeeded ...

Assignment Operation ( Its totally fun programming! )                                            One more thing in python that fascinates us is its ability to hold the values of the variable even after assignment operation. Like say:               a=2         b=a This is bound to keep the values of both a,b intact without any change.  so doing things like:                                 print a,b                 gives #a=2,b=2 And!!             One more important thing to remember is sequential assignment: what I mean is assignment is sequential in its nature.  So if we have things like:   ...

Array..so long Data organization and structure is one of the main concern of every programming language. The early languages for example C, C++ laid emphasis on using the primitive data structures such as array to store the grouped data. It had one more thing to remember, and that it was being strongly typed.   With the evolution of modern higher level language we could make the earlier so called 'typed structures' to a  more friendly and indeed beautiful implementation which could be made  to be more comprehensive as well. Python...its beauty   Higher programming language such as python gives us more power in making such things. Its feature of list makes it so easy for many a things that one can make use of. It makes it easy of doing all the things of doing the  functionality of an array and other related operations such as sorting, deleting , indexing,slicing , and  many others. With these rich featu...

Amazing...at all ..                    Well I have been programming in python for almost 2 years.But as it goes on, it has not only proved efficient but also very easy to pick up language. Hats off..to all the guys involved in making this wonderful language.                             One thing I have seen over these years is that there has been a tremendous amount of interest  as well as contribution from all across the globe.Libraries have been  updated and many more modules are included in the latest release. Graphics in python. .     One noticeable fact of Python is its easiness in graphics programming. The graphics libraries are extremely rich and very much easy to use. Compared to C++ , I would rather say that it is much easier to program in python. And even when compared to Java, for its natural AWT libraries, I would rather pick...

Its gonna be really exciting this time...hope so                                           The Google summer of code has just arrived.Hope its gonna be hit for me this time. Lotta interesting organisations  to see through....say like..Drupal,Wordpress, Samba,Sakai,RockBox and OpenIntents. Gonna catch up with the  code early on..m learning patches and diff stuff. Will see What I can do.        My favourite goes with sakai and drupal, both of which goes to give the great products to the people, and honestly I'd liked Sakai for its involvement in the educational field. Drupal is good and  m trying out on its code. Hope its gonna be all right m gonna get selected in one of them...

Android: the most popular mobile platform in the current times. Yet in the due course of its learning, one may feel a little awkward owing to its different way or otherwise platform based coding. The main problem one may find is syntax and the libraries one has to learn and know for a better programming.  Still, with passion one does not have to really worry..coz its the same old saying that  where there is a will there is a way. The main development areas for android in the coming ways will be in the cloud based services. Things like cloud based development and storage provision are coming round the corner and yet we may see many more to come in the near future.. So guys ...all my fellow programmers..go and go for it..wish u all  happy coding!

Well its not bad to have made mistakes ..after all its from them we learn.Today I 'd like to talk about problems relating to data loss during os installation. Sometimes our  disk is corrupt and terribly fails during the installation process, wiping away all the precious data stored in our hard drive. If it's that you ,then do the following(I did it): 1> Don't touch any rearrange any of your folders or even a small file. If it done then it will  wipe away all the boot record and ultimately the file content will go. 2> Then install windows xp on a small portion of the disk say 5 gigs(make it, if its not present as such small amount). 3>Install the data recovery software(Easeus is really good)  in where os is installed.Don't touch the remaining part of the disk.  4> Then use any good external hard drive to make the recovery of the lost data.But make sure you dont use the same drive for recovery. 5>Then its done. Now install any other os you w...
