Laptop Computer Problems – Display Screen

There are so many Laptop computer problems, but one of them is very common and that is display screen problems. Display screens come in various size and thickness. Newer laptops are very sleek with delicate screens, and they require extra care. There could be many problems related to display screens of a laptop. Before looking out for problems make sure you have installed the latest BIOS setting for your graphic cards. If the BIOS settings are fine then other laptop computer problems could be:

Lose Connections

Sometimes due to lose connections the screen starts flickering. There’s a cable that connects the motherboard of the laptop computer screen problemslaptop to the screen. You can rectify the problem by opening the back cover of the screen and tighten up the loose connections. But if you are not an expert and not confident enough then I would recommend you to consult an engineer for this purpose.

Screen Refresh Rate

Check whether the screen refresh rate has been kept at optimum rate that is 60 Hz. Most of the latest computers can be adjusted to more than 60 Hz. Make sure the rate is compatible with your system requirements otherwise it show problems with different programs.

Updating Video Card

When we update our computers to a newer version of operating systems and other things, we usually forget video cards. Visit your manufacturer’s website and check for any updates available. After updating the VGA card, your laptop should work properly with any graphics program and games as well.

Screen Resolution

Screen resolution is very important to look at. Simple right click on your desktop. Display Properties will open up. From their go to Settings and adjust screen resolutions that fits best with your display screen. In this way you may overcome any laptop computer problems.

Broken or Fragmented Images

If the laptops display screen is showing broken images or with random shapes then it may be screen’s problem itself or related to the CPU. To confirm this, connect your laptop to an external monitor. If the problem persists then it means the problem is with motherboard, graphics card etc. For that you need to consult a hardware specialist who will guide you or service your laptop.

Physical Problems

One of the severe problems are that of external damages to the display screens of a laptop. Any external pressure, dropping the laptop, excessive heat or moisture over the screen, can prove fatal for the screen so the only way is to replace the screen from the nearest computer repair shop.

We carry laptops to different places, exposing them to different environments that can prove harmful for them. So there’s a need for extra pampering to prevent any laptop computer problems in future.

YouTube in 3D !

There is a good news for all those viewers who are a big fan of 3D movies and videos, well now you can watch YouTube in 3D.  Yes, YouTube had recently launched the option to view all sorts of clips and videos in 3D option. Presently the feature is in beta version and the management of the site would thoroughly research and look whether people are interested to watch videos in 3D or not.

YouTube will make sure that not only Titanic and Lion king are in 3D but most of the things are viewable in 3D. Of course the site doesn’t have the capability to produce high level  3D videos just like movies originally made in 3D. The videos would be available as high as 1080p and the site would automatically change to this option. Oh yes, you definitely need 3D glasses to watch them.

Why YouTube in 3D is being offered is something I can’t guess, because not many people might be vying to watch movie clips in 3D. Still it has already started and what people are expecting out of all this is yet to be seen.

Here’s one video clip from YouTube in 3D. Experience and see whether you like it or not.

The Version Control Systems

Version control systems is an application files and pictures and other data that are stored in computer file format. Changes are made with regards to numbers that is known as ‘revision number’. For example it a set of information is defined as ‘revision 2’ and when you make changes to next level, it becomes ‘revision 3’ and so on. With the version control systems usagehelp of this revision system, the user can make changes, compare and merge files.

Principles of Operation

To summarize, the file structure is placed in what is called filing. Tools determinants, SVC allows multiple developers to work in parallel on the same file tree by allowing them to publish their changes within the group work in real time. Beyond the collaboration aspect of the SCV can also keep different versions of the same tree (which can be crucial especially when the posting of changes or the unfortunate appearance of regressive bugs). Therefore, the version control systems can be great ways to save for source files. The best known of these applications is undoubtedly CVS (Concurrent Version System) but there are others.

You said Subversion?

Subversion is one of the great family of free software is a version control systems open source. Many SVCs are used to manage source code and often offer tools for software development. Subversion differs from the latter as it allows managing any file system (including of course the source code).

Historical

Karl Fogel and Jim Blandy founded in 1995 the company Cyclic Software to develop and market support for CVS. Having spoken at length about writing a successor to CVS, Jim Blandy proposes a new theoretical model of deposit. Thus, in 2000 Brian Behlendorf (CollabNet society) offers Karl a job as project manager full time to write the future successor of CVS.

Karl’s team developing the project under a free license, it is not long in attracting developers come from everywhere. The main purpose of the project desired by Karl and his team is to provide a functional replacement for CVS. In addition there is no question to supplant but rather to develop software based on the same architecture, but that pushes some known limitations of CVS. Subversion and was thought to be taken over as easily as possible by CVS users.

After 14 months of development, Subversion became independent at the end of August 2001. So that developers continue to use CVS to replace their “baby”. Even if we have to thank for CollabNet funded much development, the Subversion project is still a major open-source project. So CollabNet owns the copyright on the code, but it is licensed under Apache / BSD-style. In short, you can download, modify, and redistribute Subversion as you wish without seeking a specific authorization to CollabNet.

Version control systems provides good and stable solutions and is supported very well. It has been well understood by engineers and has been serving different users for a long time.

Siri Software – The Revolutionary Voice Recognition System

Siri (Speech Interpretation and Recognition Interface) software is an intelligent voice recognition assistant which is Apple iOS compatible application. The application would recognize your voice and act accordingly. It canSiri perform various web functions from making calls, send voice messages, make appointments, book a table at your favorite restaurant, surfs web for you and even wakes you up and the list goes on. The best thing about Siri software is that it replies you back as if it’s a two way communication going on.

Apple Inc acquired the application in 2010 and DARPA (Defense Advanced Research Projects Agency) had funded its research and development. At the moment Siri is integrated in iPhone 4s as a part of iOS 5. The phone has been making news for this particular feature it offers. Reports are also coming that Apple plans to integrate Siri into its Tablets (iPad), with operating system iOS 6. It will support all functionality except phone dialing. Their iPad’s have stronger hardware configurations to support Siri for optimum operations.

Presently Siri software is in beta stage and needs further development to perfect itself. Many experts have reservations for Siri, due to the fact that it does not perform up to the mark. Well there’s much more time to come when this technology of voice recognition becomes perfect and common simultaneously.

Protect your Software with Shrink Wrap License

Shrink wrap license refers to contract agreement accepted by the user once the user opens up a new product. The name comes from the cellophane wrapping that tightly seals the box of the new software product. The license contains terms and conditions that are contractual in nature and once the client purchases and opens the sealed box, he is expected to abide by the agreement printed on it.

Importance of shrink wrap license agreementshrink wrap license agreement

This license is required to make a contractual relation between the manufacturer and the customer which is apart from the agreement between retailer and the customer. The agreement gives the publisher protection against any legal consequences including illegal copy and distribution of the software. Furthermore it restricts the user from editing the code, or altering the program in any way forbidden. It also limits the power of any one from reverse engineering of the software.

According to many software houses, once the cellophane coating is removed, the user has entered the agreement automatically. On the other hand there has been a legal battle across States, that agreement clauses are not visible until the wrapper is not removed. The licensing continues to be a controversy amidst number of cases against it.

Currently the method of shrink wrap license is the best method for any software publisher to maintain security for its new product or innovation. Therefore it is necessary when you launch the product, take these legal matters into account to avoid any unforeseeable event

Applescript If Then – An Example of Using Control Statements in Applescript

Applescript If Then statements are used as control statements i.e. some piece of code will run only in case if applescriptcertain conditions are met. Each if statement works as Boolean value that is used to evaluate a particular expression as either true or false. The commands which are written in the  if statement block, they are executed only if the Boolean returns the true value. If statements ends with an end if.

if  amountReceived < 1000 then

set memberStatus to “General”

else

set memberStatus to “Special”

end ifif else applescript

In the above piece of code, if the Boolean returns true (the amountReceived is less than 1000) then the instructions inside the if statement are executed. And if the Boolean returns false, then those instructions are not executed. In that case, the control is shifted to the else portion and the instructions of else statement will be executed. This combination is known as an if-then-else statement.

In the end, Applescript If Then else is easy to learn. However, practicing it by yourself makes you more clear not only about the control statements but also about development of varying programming skills in your own self.
