on

Technology has truly transformed the entire world. In today’s date when we take a look around us be noted that we live in a world which is completely surrounded by technological gadgets and other life is dependent upon the usage of those technological gadgets. Technology plays a very crucial role whenever it comes to making a life more convenient and easy. We have noticed that survive without technology is actually very difficult as there is a part of our day to day life to our work in the organization. The primary motive of Technology was to make human life more convenient and efficient at the same time and after seeing the present scenario we can say that Technology has only served its purpose. Technology has truly made life more convenient and easy as performing certain tasks with the help of technological devices has been more convenient and more efficient as less human effort is required. But with the passage of time Technology has also evolved and produces something more beneficial and productive such as artificial intelligence.

What is Artificial Intelligence?

One of the most beneficial and productive format of technological advancement which we have seen all around the world is artificial intelligence. Artificial intelligence certification the first thing which comes to our head is manmade intelligence and that is pretty much what it actually means. Humans are given Technology a pretty humanistic approach by providing them with the ability to analyze things and respond to them with the usage of human intelligence. This has been revolutionary as currently machines have the ability to perform human tasks but use the natural intelligence which is mostly displayed by humans and animals. Machines demonstrating such intelligence and consciousness are truly impeccable as if they also have an emotional distinction to react to a situation helping the user. The most common example of artificial intelligence is apple’s Siri and Amazon’s Alexa. These robots not only respond to human commands but they also understand the words and emotions which are portrayed by the user and enable them to provide recommendations or solutions. artificial intelligence is a very crucial part of the technological development in today’s world as it has actually is doubt most of the work of humans because they would not have to type a command for the device to understand.

What is Mahout?

Mahout is actually a very important part of the entire artificial intelligence platform where it primarily helps in numerous courses. The primary three causes of mahout are helping in recommendations of clustering and classification. Clustering in classification is actually a very important part of artificial intelligence which is actually executed by mahout. it works as a very constructive platform where are similar groups of data sets are executed with respect to their characteristics in order to have a proper data point among different homogeneous classes.

What is Clustering in Mahout?

Clustering in mahout is actually one of the most important parts of artificial intelligence which is also taught to numerous professionals who prefer getting artificial intelligence training. Clustering in most simple terms can be defined as dividing or creating groups in the same homogeneous platform in order to make creation of data sets much more easy and convenient. The first format of clustering which is used in mahout was primarily invented in 1969 which is considered to be one of the most simple and unsupervised learning algorithms which help the lot of professionals in solving clustering problems. This format of class 10 was primarily used by the method of vector quantization which was primarily debated some signal processing. This soon became very popular in the entire way of cluster analysis. It had a few policies such as the partition of the objects into non empty seats; it also helps in identification of numerous cluster centroids which help the professionals in there waiting the current central partition. Allotting specific resource also became much more convenient. It has been widely used in numerous organizations and industries all around The World which has been completely effective. The effectiveness of k means clustering has actually benefited numerous organizations for which it has been wide popularity since its arrival in the year 1967. There are another format of Clustering such as canopy clustering and hierarchical clustering which are primarily deleted from the parent chain of k means clustering.

Clustering has made understanding data sets much more convenient and understandable. This is one of the most important tools of mahout which is widely used and benefited from.

Running Games using Direct X Technologies

Published

on

Most Windows-based Operating Systems in today’s scenario use Direct X for accessing low-level hardware components to enhance the multimedia experience to users. Direct X is a series of APIs that facilitate this feature. As such, it is a vital component in Windows. Microsoft delivered DIRECT X to provide ease for developers in creating games and video rendering applications. Files like d3dx9_43.dll and d3dx9_41.dll establish a connection between the system application and the graphics card. In such instances, it is vital to understand the need for Direct X to run applications like games and video playback software. Thus, this article focuses on understanding what Direct X is and various aspects regarding this technology.

Direct X – A brief introduction

Direct X, often known as Direct X 3D, is a library that contains different APIs for the efficient operation of multimedia environments. These are examples. DLL files required for games and applications created using Microsoft Visual C++ and Microsoft Redistributable packages are libraries that facilitate this endeavour. In today’s world, most game developers make use of these when developing applications. As a result, Microsoft greatly assists developers in creating apps for their Operating Systems by offering outstanding libraries with different components critical to the operation of these programs.

What does Direct X do?

i) Establishes Link – The primary function of the Direct 3D technology is to establish a connection between the system application and the graphics processor. This feature facilitates the access of low-level hardware components to perform efficiently.

ii) Software Settings – Gone are the days where one manually updated configuration settings from batch files. Today, individuals using Windows-based Operating systems can change the settings on the user interface of the software. This feature is highly beneficial for individuals that are less technically empowered. As such, Direct X makes a thorough analysis of the system specifications and chooses optimal software settings to ensure the smooth performance of an application.

iii) Graphics Rendering – Another vital function of Direct X is to render graphics to a substantial extent. With the advent of improving technologies like graphic processors and system microchips, high-level rendering delivers surreal software. Big companies like Nvidia, AMD, etc., create exquisite graphic processors for systems. Direct X transfers a load of high-level processes to the GPU. By doing so, it relieves the primary processor of a lot of its duties. This feature highly enhances system performance.

Resolving Errors Related to Direct X

Various errors occur due to faulty installations of Direct X. As such, many users in today’s scenario face these errors. Here are some of the methods to resolve these errors.

i) Version Error – In a few instances, the error is trivial and easily solvable. The Direct X versions don’t satisfy the requirements of the software. As such, it is vital to ensure that the Direct X on one’s system is up-to-date. One can do so by using the “dxdiag” function offered by Windows.

ii) Reinstallation – One can also try solving these errors by reinstalling Direct X and graphics drivers. By doing so, they reset the entire configuration of the graphics processor resulting in loss of data.

iii) Download the file – In cases of corrupt or missing .dll files, one can always download these files. However, immense consideration has to be taken into account while downloading files on the internet with the advent of increasing cybercrimes.

In conclusion, Direct X technology has eased the process of developing games for Windows-based Operating systems. It also allows users with low specs to run such software. Files like d3dx9_43.dll often go missing due to various errors, as observed earlier. However, by understanding the elements in these libraries, one can resolve such issues with ease.

Know the Key Points That Outline the Prince 2® Framework

Published

on

PRINCE is the abbreviation for Projects in Controlled Environments. It was first invented in the UK as a step by the Government to try out new methodologies for project management. However, it soon gained vast popularity across the globe owing to its good results. AXELOS is the authority figure behind the PRINCE framework. This means that when you get the PRINCE 2 certification, it is the accreditation from AXELOS that will gain you recognition in any part of the world, wherever an organization is searching for PRINCE 2® experts to be hired. So gear yourself up, as we will take a deep dive into the key points of the PRINCE 2® framework in this article!

1.     Your Project Should Always Have a Business Justification –

Starting from the initial steps to the end results, according to the guidelines mentioned in the PRINCE2® foundation and practitioner course, every step of the project must always have a justification. There must be a factor of accountability present where the upper management must keep a check on where there is a good return on investment. Not only that, the risks of the object must be controlled, and the benefits must outweigh the setbacks of the project.

2.     Everyone Must Be Aware of Their Roles and Responsibilities –

An important aspect of the PRINCE 2® methodology is that every team member must be thoroughly aware of their roles. Not only that, but everyone must also know their responsibilities as a part of a team. This is in order to ensure that there are a few setbacks, confusion, and drastic delays as possible in the follow-up meetings. It is a common scenario in meetings to hear that “I thought Mr.X was responsible to take care of this task.” The PRINCE 2® certified project manager is responsible to look out for these scenarios.

3.     The Team Members Must Have a Controlled Focus but With a Little Room for Improvisation –

If you are working in a PRINCE 2® environment, you are expected to focus your full attention on meeting the requirements to achieve the end goal. But at the same time, you must maintain the quality of your work to the highest standard. However, the prince 2 methodology also leaves space for improvisation according to your specific work area-related requirements. If you are adopting the method, you must first identify which areas can be improvised in the methodology.

4.     The Team Must Always Keep on Evolving –

The PRINCE 2® methodology mentions a controlled environment, meaning that there must be a “lessons learned” log maintained by the team. This ensures that mistakes are avoided as much as possible. There must also be retrospective meetings where each member of the team gets to reflect on their overall performance.

Final Word

The PRINCE 2® methodology has different levels of qualification courses. This includes the PRINCE 2® Foundation course, the second one is the practitioner course. Make sure that you choose one according to your qualifications!

How to solve the error message “ We couldn’t complete the updates, undoing changes – don’t turn off your computer ” on Windows 10? If you are experiencing this problem then you have come to the right site because this article will help you to get out of the problem.

Well, this Windows 10 is the latest edition of the Operating System made by Microsoft and like all other OS Windows 10 also definitely has a lot of problems. But what I’m focusing on here is when downloading a new update ( update ) and restarting the PC, the update process just crashes and Windows can’t start and what appears is an error message, read more.

And it turned out that we were just stuck in the message then I tried to wait until it was finished but in the end it didn’t work, it just restarted  by itself. In addition to the error above after the restart process is  complete, you may start seeing some progress messages like this:

“Installing Updates 15% We couldn’t complete the updates, Undoing changes, Don’t turn off your –  computer Restarting” and I have good news that the process goes up again to 30% and the bad news is the computer restarts again and this will continue to occur if you do not make changes to your PC.

Cause of error We couldn’t complete the update, undoing changes

  • Windows Update can’t download smoothly. If the updates that Windows installed don’t download properly, this could cause an error to appear.
  • Insufficient hard disk space. In some cases, if you don’t have enough space for updates on your system volume, the problem could also be because of that.
  • The update was interrupted during installation. If the update is interrupted during the installation process like PC shuts down, etc. Errors can be caused by it.
  • System files are corrupted. Another factor causing this problem to appear is your corrupted system files.
  • There are applications, drivers etc that are not compatible with your PC. If indeed you have recently installed additional applications then it is highly recommended to delete them.

How to solve the error message We couldn’t complete the updates, undoing changes

Run CMD (Command Prompt) in Administrator mode.

Now type the following code then hit enter for each line of code:

  1. net stop wuauserv
    2. net stop bits
    3. net stop cryptSvc
    4. net stop msiserver

Then open file explorer then delete all files and folders in  C:WindowsSoftwareDistribution .

Now open CMD again and still in admin mode then type the following code and hit enter:

  1. net start wuauserv
    2. net start cryptSvc
    3. net start bits
    4. net start msiserver

Restart your PC to save the rules.

Try to reinstall Windows updates and this time it should work.

If you’re afraid you’re having the same or another problem, you can create a restore point before you download Windows updates.

Download Windows Update Troubleshooter

  • If the error message sometimes still appears then you should try methods 1-6 above.

Run SFC and DISM

  • Still run the command prompt in the manner described above.
  • Type sfc /scannow in cmd and press enter.
  • Wait until the scanning process is complete usually takes 5-15 minutes.
  • If so then type the following code and press enter on each line of code:
  1. Dism /Online /Cleanup-Image /CheckHealth
    2. Dism /Online /Cleanup-Image /ScanHealth
    3. Dism /online /Cleanup-Image /startcomponentcleanup
    4. Dism /Online /Cleanup-Image /RestoreHealth
  • Attention: the above process is not a fast process, this process can take up to 2 hours or even 5 hours according to your computer specifications.
  • After the Dism process is run, then you repeat again method no 2 in this section.
  • Restart the PC and the problem will be resolved.

Turn off Secure Boot

  • Restart your PC.
  • When the computer starts up, please enter the BIOS menu.

  •  Restart your PC and the error should no longer appear.
  • If successful, please re-enable secure boot earlier.

Remove System Reserved Partition

Open CMD like method no 8 above and enter the following code:

  1. bcdboot C:Windows /s C:
    2. diskpart
    3. list vol
    4. select vol (Select System Volume)
    5. act
    6. list vol
    7. select vol (Select System Reserved Volume)
    8. inactive
    9. exit

You can see the system volume and system reserved volume in the info and label section of cmd.

Configure BCD with the following code:

  1. bcdedit /set {bootmgr} device partition=C:
    2. bcdedit /set {default} device partition=C:
    3. bcdedit /set {default} osdevice partition=C:

Before making changes or rebooting , make sure you have Windows installation DVD or WinPE/WinRE Cd or USB flash Drive in case of Windows Boot failure. If Windows won’t boot, use the Windows installation disc to boot  which can be seen here: How to Make a WinPE Bootable USB .

After that, at the command prompt type the following code:

  1. bootrec /fixmbr
    2. bootrec /fixboot
    3. bootrec /rebuildbcd

After the reboot process , move WinRE from the system reserved partition to the system partition .

Now reopen the command prompt and type the code below and change the drive letter according to your partition letter which can be seen on diskpart.

  1. diskpart
    2. list vol
    3. select vol <Recovery Volume>
    4. assign let=R
    5. Disable WinRE:
    6. reagentc /disable
  1. Remove WinRE from the reserved partition with the code  rd R:Recovery .
  2. Copy WinRE to the system partition with the code  robocopy C:WindowsSystem32Recovery R:RecoveryWindowsRE WinRE.wim /copyall /dcopy:t .
  3. Configure WinRE :  reagentc /setreimage /path C:RecoveryWindowsRE .
  4. Finally enable WinRE :  reagentc /enable .
  5. For future use, create a new partition at the end of the drive (after the OS partition) and save the WinRE and OSI (Original System Installation) folder containing all the files contained in the Windows 10 DVD. Make sure you have enough free space on your hard disk to create this partition drive (usually 100GB). If you choose to create this partition, it is important that you set the partition ID flag to 27 (0x27) using Diskpart, which determines that it is the Recovery partition.

The final word

If nothing else works then Restore your PC to an earlier time ( restore point ), remove the problematic update from Control Panel, disable automatic updates and use your PC normally until Microsoft attempts to fix this update issue. In a few days, maybe 20-30 days, try to install the update again, if it still fails, please try the above method again. As for if you don’t want Windows updates and want Windows to return to normal then the most effective solution is to reinstall.

That’s about How to Overcome We couldn’t complete the updates, undoing changes in Windows 10, please ask if there are other problems in the comments section. Thank you..
