You don’t have to worry about these problems because they have ready solutions. There are some common video controller driver problems but we are going to look closely at the three main ones in this discuss. It is important we go through these 3 video controller driver problems so that you can ascertain if you had experienced any of such before.

One of the major problems that majority of graphic cards users experience at one time or the other is seeing artifacts while making use of applications that normally control the gfx cards. This usually occurs to those that use 3D chip engines that are heavier. It isn’t enough to know any of these video controller driver problems without noting the solutions we will offer at the last paragraph of this write-up.

The second common problem of the video control driver is observing the whole screen may be locking up and you may notice that your computer has a universal crash. Thus, you may see the blue screen after which your system automatically gets restarted. This kind of video card problem may be as a result of misrepresentation or inappropriate communication between the files of the system. It may also occur as a result of some kind of file corruption or simply version clash. This version clash is quite avoidable but it isn’t everybody that realizes that many websites still have outdated versions of certain drivers. You have to ensure that you get your drivers from websites that are up to date, to the last minute.

The most common problem among the top three video controller driver problems is having limited amount of colors and the desktop looking quite pixilated with large fonts. This is as a result of the computer’s inability to detect the video card at all and this will cause it to always revert to the usual VGA standard setting.

You may be chasing a wild goose if you haven’t realized that the underlying problems here are because of one form of driver defect or the other. The simplest solution lies on finding driver detective that will help to automatically find out and fix any of these sorts of problems. It is very easy for any to go online, search and download any of the drivers that is needed but it is best if you are getting your drivers form websites that are reliable and has relative credibility in the industry. That is the only guaranteed way of ensuring that the drivers you get are compatible with your browsing system and are up to date.

Even with an encrypted keyboard, you need to be concerned with the type of encryption in use. A 2007 white paper from Dreamlab Technologies AG reported that encrypted keyboards from leading manufacturers are susceptible to surprisingly simple brute-force attacks.

That’s not the case with wireless keyboards encrypted with AES Secure technology.

AES, or the Advanced Encryption Standard, is a powerful cryptographic algorithm chosen by the US government to protect the most sensitive information.

In an AES Secure wireless keyboard, keystrokes are encrypted with a 128-bit secret key before being transmitted over the air to a receiver attached to the computer. That receiver then applies the secret key, removes the encryption, and uncovers the original keystrokes. Both encryption and decryption involve a series of complicated mathematical operations, but it all happens so fast, you can go right on typing without ever noticing a delay.

What makes an AES Secure wireless keyboard so impervious to attack is the 128 bit secret key. Previous encryption standards -including the ones used in keyboards studied by Dreamlab Technologies- used 32 or 64 bit keys. A hacker trying a brute-force attack on one of these encrypted keyboards could expect to find the secret key by trying as few as 256 possible key values-a very fast and simple task by a computer equipped with the appropriate software.

AES doubles the key size from 64 to 128 bits, but the time and energy needed to discover the key by brute force doesn’t just double – it multiplies by 2 to the 64th power, or more than 18 billion billions. In the 10 years since the adoption of the AES encryption standard, no one has ever succeeded in breaking an AES encrypted transmission. In fact, Wikipedia estimates that with current computer speeds, it could take longer than the age of the universe to discover a 128-bit AES key by brute force techniques.

AES is the encryption algorithm used in wireless keyboards made by Wireless Computing of Austin, Texas.

Below are some of the cases, where incautious use of DiskPart causes data loss or inaccessibility:

DiskPart converts a basic disk to a dynamic disk. Before using DiskPart, you must ensure that the disk must be empty or contains either primary volume or logical volume to avoid loss of data. Furthermore, the basic disks containing fault-tolerant disk driver (FtDisk), must be converted using Disk manager rather than DiskPart before upgrading, or else, these situations will lead to data loss.

If the hard disk has already been upgraded to dynamic disk, then usage of DiskPart command can damage the partition table leading to data loss and the need of partition recovery becomes inevitable.

DiskPart verifies the particular partition that is is capable of containing an operating system’s startup files. If you mistakenly mark a part as active and it does not contain the operating system’s startup files, your computer won’t start leaving the data inaccessible.

On basic disks, the partitions are deleted through focus. Thus incorrect choosing of partition focus and thereby deletion causes data loss. Partitions lost in this way can only be recovered using any good partition recovery software.

Be extremely careful while using the ‘Create Partition msr’ command by DiskPart as it creates Microsoft reserved partitions as the first partition. However, GUID Partition Table (GPT) disks require a particular partition layout and creating Microsoft reserved partitions as the first partition could cause the disk to become unreadable resulting in data loss.

All these cases of data inaccessibility or loss necessitate Partition Recovery as those partitions contain your valuable data. Furthermore, in the above cases, when backup is not available or failed to restore the data due to any erroneous reason, use of partition recovery software to get back your data is the only option left.

These Partition Recovery tools are safe and are easy to use without the need of any prior technical knowledge. The application use a certain set of scanning algorithms which help extracting lost information.

Stellar Phoenix Windows Data Recovery is one of the reliable and effective Partition Recovery software to recover lost, corrupted or inaccessible partition. This software offers risk free recovery through effective scanning and supports all FAT16, FAT32, VFAT, NTFS, NTFS5 file systems.

Let’s say you have a column in a database that collects phone numbers from a web form and that form doesn’t have any JavaScript parsing the code into the three standard parts of a phone number (area code, prefix, and telroot). This data is being dumped into a leads file and the manager from the sales department comes down and asks you to help split up the leads by area code.

The first thing you need to do in a situation like this is become aware of what kind of data you’re looking at. Select out the first 100 or so rows and get an idea of what shape the data is in. In this case you can see there are several types of phone numbers entered.

I’ve limited the example above to just a few of the types of numbers you might find if you allowed users free form access to storing their phone numbers.

* 3,3,4
* Parenthesis, dashes, and 3,3,4
* Blank, null, or N/A
* Parenthesis, dashes, spaces, and 3,3,4
* 10 numbers
* Extensions
* International numbers

The Solution

So how can you deal with all these situations? Use SUBSTRING.

SUBSTRING (string, startPosition, length)
Using this function you can check out the first three characters of each phone number.

SELECT TOP 100

phone, SUBSTRING(phone, 1, 3) AS [area code]
FROM sourceTable (READCOMMITED)

When looking at the results, you will see that this only shows you the first three characters of the phone number. While the results appear to be accurate in some cases, you should immediately see the exception cases that this doesn’t handle. This solution cannot handle cases with parenthesis, international numbers, NULL, blank, or invalid numbers.

If you are moving to Quebec where french is spoken you should learn a bit before embarking on your trip. You should know enough of the language to get around and make yourself understood. The rest you can learn on the way.

Before deciding on where you want to move to, it is important that you study the available options. Learn about each city and especially about the city where you want to live. Learn their history and the time they take tea and eat lunch. Find out about their train system and other transportation available.

Computer system vary, telephone systems change from continent to continent too. You must train in these simple matters before applying for a job. Your future employer must know that you are ready and willing to study and do whatever it takes to fit not only into the position but into the surroundings.

You must check with your national embassy to ensure if it is possible for you to go work in Canada, and if there are any specific documents you must complete to do so. Things are done differently in different places. It is a good idea to look at the big picture before staring at the small details.

Before attempting a permanent move, find out if there are courses or some sort of training you can get in your field in Canada. It is always a good idea to test the waters before diving in. It is possible that your company will allow you to get training elsewhere and keep your job waiting for you. You will be paying for the training; all you want is for them to hold your job for a couple of weeks.

This way you will be able to experiment the working environment in the place where you want to live. You will be able to test the budget possibilities and you will get a chance to look around and hunt for a possible opportunity. Any foreign job experience looks good in a resume so go slow but constantly forward until you reach your goals.

Want to advance in your career? Why not invest in some training courses. Professional certifications such as CCNA training, or quickbooks training can make you stand out from the crowd.

My article on the Hottest IT certifications for 2010 mentioned Green IT as a dark horse in the certification chase. My list of top ten certs then, looked like this:- (Experienced)

1. VMWare VCP
2. Cisco’s Cloud Computing
3. MCSE -Security
4. Cisco’s CCIE Security
5. SQL
6. MCITP
7. RHCE
8. Green IT
9. CWSP
10. anything Citrix

Today, though not surprised, I choose to move Green IT from #8 to #1. Green IT to a greater extent, has not been thoroughly defined. Being relatively new, and still being debated, there is still a lot of work to be done in creating a curriculum that truly covers the length, breadth and depth of creating a sustainable Green IT environment. The books and articles that I have read seem to place the emphasis on Green Data centers. The data center is and will continue to be the focal point for energy conservation, but Greening your IT department involves everything from the data center to edge devices to users, suppliers and other business partners. It covers marketing, transport, waste disposable, and Corporate Social Responsibility.

The questions that has been asked of me by some readers of my last article is, “Is there a Green IT certification?”. Another question is “Which Green IT certification is the best?”. As of this writing I am convinced that the certifications that are available today will have to evolve as laws and regulations are presented. There are great books, a huge number of whitepapers and tons of YouTube videos covering Green IT. Recently CompTIA released their Green IT (Strata) certification. I investigated this cert and though I commend CompTIA for the foresight, I believe the cert is pretty elementary. I will, however, support any student or professional to pursue this certification. I have searched for the text but it seems to be available only as an e-book.

The CompTIA Green IT (Strata) certification is a 30 question/ 60 minute exam with a passing score of 70%. Prerequisites for attempting the certification is CompTIA Server+; CompTIA A+ or eighteen months work experience. Although I am a staunch supporter of the quality of exams coming from this organization, I am inclined to believe that this Green IT curriculum is pretty superficial. I tend to believe it follows the mantra of “It’s easy going Green” and “100 Things You can do to Save the World”. In your study of Green IT you will quickly appreciate the depth of knowledge needed to really present or initiate a Green IT initiative. However, in view of the lack of quality study tracks available, I would encourage obtaining this qualification but would quickly advise that it is only the tip of the iceberg.

My favorite Green IT certification is definitely the program presented by the Chartered Institute for IT (BCS).- http://www.bcs.org. The text which I obtained from London through the kindness of an ex-student (thank you, Keno), is an exceptionally written book. Written by Mr. Mark G. O’Neil, the Green IT For Sustainable Business Practice is packed with “no fat” information about Green IT policies, drivers, definitions and management. This curriculum in my opinion presents a more realistic look at what is entailed in the field of Greening an IT department. Though it addresses the data center, the book also identifies the management issues from the end user to the supplier, partners, disposal, laws and regulations. I will readily admit that it was written for the UK professional but still is valuable to any Green IT professional. I will attempt this exam soon and will therefore be more informed about it. Stay tuned.

As I have stated in numerous posts, the availability of information on the internet is never ending. There are whitepapers from Cisco, IBM, EPEAT, EPA, GreenPeace etc. My recommendation to the pursuer is to submerge oneself in the understanding of IT, it’s design, management, weaknesses and add the information from a sustainable approach. Wikipedia still remains my favorite.

Although not identified as a Green IT certification, it is wise to examine ITIL. For the reader who is not familiar with these certs, ITIL Information Technology Infrastructure Library is geared towards presenting high quality services to the IT environment. The ITIL framework is concerned with planning, building, moving and operating IT services with the most efficiency and therefore must include environmental strategies. Another document that would advance your understanding of Green IT is the ISO14001 standard. You do not need to purchase a book on this because the information can be found online.

Like I hinted earlier, the fact that Green IT can be considered new, there is the opportunity to get in to an area that will definitely be in demand more and more. Build your knowledge base with information on supply chains, waste reduction, energy conservation, carbon emissions, carbon trading, EPEAT, recycling and the numerous other areas that are included in a Green IT initiative. The Gartner website has quality information, the EPA, Carbon Trust, Google and YouTube are irreplaceable sources of knowledge. I hope this article answers the numerous readers who have contacted me.

When you backup volume gets locked, the Time Machine icon is replaced with simple volume icon with a small lock on it. In such cases, the volume can not be mounted and you can not access data stored on it. In case the volume is mountable and you attach it to a newly installed Mac computer, the same problem occurs with this computer as well. Your system drives get locked and it become totally unusable.

Reason of locked backup volume or Time Machine volume in Mac OS X?

This problem generally occurs after you upgrade the version of your operating system. Upgrading the operating system sometimes damages the disk permissions and leads to this behavior. Permissions may also get damaged due to virus infection and improper system shutdown.

Mac OS X operating system includes a subsystem, which is based on UNIX-style OS that employs permissions in file system. Every volume, file, and directory on your hard drive has a set of privileges, which determines who can access the data.

How to address permission problems in Mac OS X?

Mac OS X operating system facilitates you an inbuilt disk recovery Mac utility to fix permission corruption issues and disk integrity problems. You can run this utility from the installation disk of Mac OS X operating system.

In case the corruption is serious and Disk Utility is unable to fix it, your data remains inaccessible. At this point, you need to format the Mac OS X hard drive and reinstall operating system. However, it removes all the stored data from disk and put you in need of Mac data recovery solutions.

Mac Recovery software are capable of thoroughly scanning affected disk and extracting all inaccessible data from it. They are pretty safe and easy to use.

Stellar Phoenix Macintosh Data Recovery is the most comprehensive utility to effectively recover lost data from Mac OS X-supported storage media. The software works well with Mac OS X 10.6 Snow Leopard, 10.5 Leopard, 10.4 Tiger, and 10.3.9 Panther. It recovers missing data from HFS, HFS+, HFSX, HFS Wrapper, and FAT file system volumes.
