3 Main Causes of Kernel Errors

A kernel error is a failure in some code critical to Windows. If you have ever encountered a Blue Screen of Death (BSoD), then you have seen a kernel error. Windows is actually several layers of programs made to work together. You can think of Windows as if it were your body, with many pieces working together to make a whole, and, like your body, some parts of Windows are more important than others.

The kernel is the most important part of Windows. It includes critical programs to handle things like memory management and device drivers for the graphics card. These programs are like a body's heart and brain. If something in the kernel crashes, it will often cause all of Windows to crash.

Software Failures

Because there are a lot of programs in the kernel, there are many opportunities for bugs to appear. Although Microsoft does extensive testing to get rid of bugs, their testing facilities can not run through all the combinations that billions of computers use with Windows when some bugs get through.

However, many of the kernel failures are in device drivers written by companies that make hardware, not by Microsoft. Your graphics card, for example, probably uses a driver created by the video company. These companies often work with Microsoft to test their drivers, but having companies working together adds an additional layer of complexity.

Hardware Failures

A hardware failure can cause a kernel error. If your graphics card fails, it can send bad data to the graphics device driver, which then crashes, creating a kernel error. If your hard disk fails, it can corrupt files used by Windows and cause the programs that use those files to crash.

Registry Failures

Registry failures can cause kernel errors. The registry is a database of information that Windows uses to store information about programs. If the registry gets corrupt, the programs that use it can cause kernel errors.

Registry corruption can come from either software or hardware failures. Software corruption can come from a bug in one of the programs that writes information out to the registry. Or if you turn off your computer without doing a complete shutdown, the registry files may not get completely written to the disk. Hardware corruption can happen when the hard disk fails causing parts of the registry files to be lost. It's a good idea to do some research on kernel errors and other registry issues.

How to Change the MPI Node Address For a Siemens S7-300 PLC

I have seven Siemens S7-300 PLCs connected together using the MPI (Multi Point Interface) interface. The Siemens MPI protocol is used by Siemens PLCs to communicate with external devices. I want to rename each of the seven PLCs. Here are the steps to accomplish that task.

First, connect your MPI cable to the first PLC. I will be connecting my laptop to each PLC individually. Power up the PLC and open Simatic Manager. The "New Project" Wizard window will open. Just click Cancel to close the window. Now click the Accessible Nodes icon on the toolbar. A window will open showing the identification of the PLC you are connected to. My window is showing MPI = 2 (directly). Make a note of this address and close the window.

Next we need to download a hardware configuration to the PLC. This is where we will rename the PLC node address. There are probably a couple of different ways to do this – following is how I accomplish this. All seven of my PLCs are the same model; Therefore, I am using the same hardware configuration. For the obvious reasons, I want to give each a different MPI node address. I have a project file that contains all seven of my PLC programs and one hardware configuration file. I open the one hardware configuration file, and then double click Hardware in the right hand window. This will open the HW Configuration window. In this window you should see your PLC with its MPI address given.

Remember when we clicked the Accessible Nodes icon and saw MPI = 2 (directly)? My Hardware Configuration Window is showing a MPI address of 7. Place your mouse cursor on the 7 and double click. Your CPU Properties window will open. It should open to the General tab. Look down and you will see Interface Type MPI with an address of 7. Click Properties and the MPI interface Properties window will open. Using the pull down menu, choose your MPI node address and make sure the MPI (1) 187.5kbps is highlighted and click OK. You are now back on the CPU Properties window where you will see your address has changed. Click OK and you will go back to the Hard Ware window where you can verify your MPI node address has changed.

You will now click the Save and Compile icon and then click the download icon. The Select Target Module window will open. Click OK and the Select Node Address window will open. Here you will see the MPI node address you assigned earlier. You will need to click the View button right below this. You will see the current node address appear, this should be the same as what you saw earlier when you clicked the Accessible Nodes icon. Simply click on this number and you will see it appear in the MPI address slot under the Enter connection to target station. Click OK and the Download to Module window will open. Click OK and the Stop Target Modules window will open. Click OK and the "Do you want to start the module?" Window will open. Click Yes.

Now go back to the SIMATIC Manager window and click the accessible nodes icon. You will see your new MPI node address. You can see this same article with pictures at http://www.morerobototics.com .

Texas Two Step Strategy – Everything You Need to Know

The Texas Two Step lottery is a great example of a game that is both strategic and fun. The state lottery is an excellent arena for you to shell out your extra dollars while learning about alternative lotto mechanics. In the state of Texas, the Texas Two Step is considered to be the most popular form of lottery. The game beings when an individual is asked to pick four number from and in between 1 to 35. Like most lotto types, this also has a bonus ball number, which can increase your chances of winning. The grand price for this unique game does not go below two hundred thousand dollars so long as you make five matches. If you are also quite hesitant to pick your own number, the quick pick system also applies to the Texas Two Step lottery. A multi-draw feature also allows you to bet for ten advance drawings at once by simply making a distinguishable mark in the designated ticket boxes. Single plays cost only US$1 each and can reflect winnings up to a hundred thousand dollars.

Most lottery systems base on luck as foundation for winning. Unfortunately, even with the convenience of quick picks and other strategies, chances of winning are still small. One effective way to increase the chances of gaining back positive results from your chosen number is by adhering to the Wheeling Systems. Generally, wheeling systems do not guarantee an automatic win after placing your number picks in the Texas Two Step. However, the mechanism gives you more chances of bringing home multiple tier prizes as opposed to you simply randomly selecting the number, or relying on quick picks. The odds of winning the Texas Two Step prize are statistically ranging from 1 to 32. The overall ratio of victory can be quite unsatisfactory if played with mere dependence on luck. Although you can win $5 for simply matching the bonus ball number, naturally, anyone would still want to vie for the grand prize.

There are also a handful of lotto software that provide good combination numbers for players. Most people confirm the effectiveness of most online programs in tracking the best numeral combinations for lottery. You may program these to suit your needs and according to the type of lottery that you participate in. For Texas Two Step, it is much easier to use a software to calculate possible combinations as it has lesser selections or numbers compared to most lotto games.

For serious lotto players, individuals simply log onto the website and place their bets randomly. Sites also offer a few tips and strategies on how to best employ their gaming techniques. You may be able to view advices on when is the best time to place your bets and how to purchase your tickets quickly. Other websites also present lottery news, which is also an effective way to keep track of your bets. Bear in mind that in order for a player to achieve positive results while playing lotto, the correct strategy and technique must put in place so as to lead you to triumph and victory.

Define Computer Hardware

It is quite well known that the working of the computer is dropped by hardware and software. One can define computer hardware as the electronic, magnetic, and electric devices that carry out the computing functions. Hardware is the physical components of the computer like microprocessor, hard disks, RAM, and motherboard. The peripheral devices such as monitor, mouse, keyboard, printer, and speakers can also be included in the list of hardware parts. The programs that run on the computers like Windows, C ++, and Photoshop are the software parts of the computer. A good example for an easy understanding of hardware-software definition is music CDs. The actual compact disk is the hardware, while the songs and music in the CD are the software parts.

There is another way to define computer hardware. Hardware devices are the executors of the commands provided by software applications. For example, let us see what happens when you click the print button of the web browsing software. The software application provides a command to the processor, which is the central part of all computer hardware. Processor in turn checks for an attached printer. If the printer is ready, the software will get a positive response from the processor. Then the software application provides instruction to the printer via the processor to print the web page. In that sense, hardware parts are the foot soldiers and software applications are the commanders in the digital operation that takes place within a computer.

The main player of computer hardware is unduly the microprocessor. It is the sun in the solar system of computer hardware devices. It is the central component and all other components work around it. It is an integrated chip on which a number of functions are incorporated. Two specifications determine its efficiency. One is its processing speed, which is measured in gigahertz. The other is its bit rate. Commonly available processors are 32 bit and 64 bit. The bit rate is a measure of the efficiency of a processor to carry out multiple operations at the same time.

One can not define computer hardware without mentioning the two types of memory used in computers. One is permanent memory. It refers to the magnetic storage capacity of hard disk. It is measured in gigabytes. The second is RAM or random access memory. This memory is able to store data only when the computer is switched on. The memory will lose all the data when the computer is switched off.

Another important product that one should mention when one defines computer hardware is motherboard. It is the electric and electronic circuit board on which all the other components are inserted. There are several other kinds of products such as sound card, video card, network card, and modem that complete the hardware spectrum.

Advantages and Disadvantages of Professional Shopping Cart Software

Advantages & Disadvantages of professional shopping cart software As e-Commerce is becoming a regular technique in the business industry it appears that more and more software development firms are developing professional shopping cart software to be released in the market. There is currently a huge range of free shopping cart software that has been released, and it seems that most e-Commerce website owners prefer these free systems over paid for professional shopping cart software. In this article we are going to look at the advantages and disadvantages of professional shopping cart software.

Advantages

• Even though you will have to pay for the solution, you get a cart package that has been fully developed, tested and used in the real working world by other e-Commerce websites. If the solution is used by a popular website service then the chances are it has been under more than enough testing to be deemed ready for use.

• Professional shopping cart software will be supported by the people who developed it. A lot of free solutions out there are simply developed and then discontinued as the freelance developers move onto their next project. Support is essential if you are going to want upgrades as mentioned in our next point.

• As the system is supported, the development team are likely to fix any bugs that may occur and provide patches and security fixes. This means the shopping cart software will only get better as time goes on and furthermore improve your e-Commerce website.

• Your site is likely to be more secure when using a professional software solution as in most cases the it developed house private content management systems. This improves security as public content management systems such as WordPress are constantly under threat from hackers as they try to compromise the free source code.

• Another huge advantage of using professionally developed software in e-Commerce is that they will already support a huge range of different payment options for your customers. There are various carts – that only offer PayPal for payment by standard, and it can take a very long time to find plug-ins or figure out how to add other methods yourself. With professional software you can save time and possibly money as it is all included.

Disadvantages

• Your e-Commerce venture might be a small time project and professional cart does cost money which you may not have. In this case you may have to make do with a free shopping cart solution. The good part of conducting business online is that after you have made profit with the free system you can reinvest your money to buy a professional package.

• You trust the developers to do everything they promise to ensure the best experience. It might be slightly difficult to use at first and you might have to spend some time getting used to the bespoke system. You also have to understand that you are vulnerable until patches are made if a security flaw is found.

Kitchen Design Ideas

Kitchens have so many design options that they are literally never ending. Kitchen design ideas include features such as cabinetry, tiles, counter tops, appliances, hardware and fixtures. Each feature on its own has a multitude of design options and the possible combinations are endless. Two identical kitchens with only one different feature can look like very different kitchens when finished. Because of the vast number of design options, thoroughly research what products are available on the market and get a fairly good idea what it is you are looking for.

The main feature in any kitchen is the cabinetry. It is more often than not the first thing that people notice in a kitchen. The layout of the cabinetry is unique to each kitchen. Measure the size of your kitchen and determine the types of cabinets and where you would like them placed. If you have a solid wall with no windows, doors or appliances opt for floor to ceiling cabinets full of drawers for storage. Include a broom or cleaning closet in these cupboards. Glass fronts in corner cabinets are a popular design feature. Cabinets have a wide variety of door styles. There are recessed, flat paneled and raised cabinet doors. Each of these options comes with several design choices. Once you have picked the design of your cabinets you need to decide on the stain that suits your kitchen space. Opt for lighter colored stains for smaller kitchens to keep them feeling open and spacious.

Counter tops are also an important feature in a kitchen. They too are highly visible. Counter tops should be chosen for durability as well as looks. Granite counter tops are the most popular choice today. You may also choose from engineered stone, ceramic tile, laminates, wood and stainless steel. The material and color of your counter tops should compliment your cabinetry, backslash and tiles. If your kitchen is a large room but does not have a lot of counter space you might want to consider adding an island for additional space. Not only does an island adds counter space but also storage space.

Flooring is an integral kitchen feature. Most kitchens are done with ceramic tile flooring but wood floors and laminates are growing in popularity. Many kitchens have tiled backslashes. Be sure that the tiles used in your backslash compliment the flooring. Besides the type of flooring you use, you must also pick a color of tile, wood or laminate as well as texture. Quite often a kitchen with light colored cabinetry will look best with a slightly darker floor and vice-versa. Contrast between the cabinetry and the flooring, no matter how small, creates the illusion of depth.

The kitchen design ideas listed above are just the tip of the iceberg. We have not even touched on cabinet hardware, lighting fixtures, sinks and taps, paint colors or appliances. Matching appliances are ideal in any kitchen. Stainless steel appliances are a favorite because they match just about any kitchen design. Families with small children may wish to consider black appliances since stainless steel shows fingerprints. Put as much thought into the small features as you do the larger ones. Something as simple as buying the wrong cabinet hardware can ruin the look of the completed project.

How to Retrieve Deleted Text Messages & Not Go Crazy in the Process

It’s happened to all of us. We’ve deleted a text message only to realize a short while later that we either deleted the wrong message, or we need to retrieve information off one of the deleted text messages. We then frantically search out ways online how to retrieve deleted text messages hoping to find an easy solution. We pour through websites pulling our hair out because we can’t find an easy solution.

Ultimately we walk away dismayed because either we were not able to find any solutions on how to retrieve deleted text messages, or the solutions we found seemed to require so much “detective” work, that the solution itself should be on a an episode of CSI.

Are there really any “easy” ways to retrieve deleted messages?

The good news is that YES, there are a couple options that do exist which enable anyone to easily recover deleted texts, and both are not only very affordable, but both work exactly as advertised.

Before we dig into the solutions, there is one solution that is often discussed, which does not work, although many people do still talk about it.

What does NOT work?

Going to your own phone carrier is not going to be a viable option. Yes, they are required by law to keep records of your communication (SMS, call, etc.), but they are not required to turn over their logs to you, unless requested by a court of law. You cannot call up AT&T, Verizon or Sprint and tell them you want to retrieve a deleted text message from last week because there is something really important within the contents of the message. It just wont work.

The only information AT&T, Verizon, Sprint, or any other cell phone carrier is going to provide you is the number, date, and time of a call or message. You can plead all you want, but they will not be able to do anything, so it’s not worth your time to attempt this approach.

What DOES work?

There are actually two options available for anyone who is looking for information on how to retrieve deleted text messages. These options rank from the “quick and easy” to the more difficult, but also the most effective.

1) Quick & easy method.

The ‘quick & easy method’ is to buy a SIM card reader, often referred to as a SIM card spy device. This device looks like a USB reader, and the way it works is you remove the SIM card out of your phone, and then place the SIM card into the SIM card reader, and then plug the reader into your computer. Using the included software (of the SIM card reader), you’ll be able to immediately retrieve and read deleted text messages. The time frame will vary, based on what new information is overwritten on the SIM card, but you’ll at least be able to retrieve and read the last 15-20 messages and scan through your call history and contacts, even if they were all deleted.

Positives of this approach?

  • Very easy.
  • Enables you to quickly recover deleted messages.
  • Does not require software to be installed prior to the message being deleted.

Negatives of this approach?

  • A bit costly.
  • Limited cell phone support.
  • Does not work on CDMA networks.

2) More difficult, but most effective method.

The more difficult, but most effective method’ is to purchase a cell phone monitoring app that is often used to spy on cheating spouses, monitor teen cell phone use, track cell phone location, and locate missing or stolen cell phones. These apps (often called spy apps or spy phone software) are often used by people who want an easy and convenient way to back up and store all their own personal cell phone data. The reason why this method is fast becoming a popular way to back up their own personal cell phone data is because everything happens automatically. There is no “syncing” required, or any buttons or settings to worry about. Your cell phone data (text messages, call history, etc.) are automatically backed up every single day. This means if you ever delete a text message, and then need to quickly recover it, all you have to do is log onto your account and then in just a few clicks, you’ll have full contents of every message that was either sent or received from your phone. In addition, you’ll get access to all your call logs and contacts.

The reason why this is a more difficult method, is because it requires that you download the software from your cell phone’s web browser and install the application on your phone. Not everyone is comfortable downloading cell phone apps from the internet using their phone’s web browser. However, once you do complete the download, the actual installation is similar to installing an app on your computer. If you are willing to roll the dice and go with this method, you’ll be very happy with the results. It’s essentially a real time person back up solution that requires absolutely ZERO work on your part. Everything is done for you. The only drawback with this approach is that it does require you to install the software BEFORE you delete the text message that you want to retrieve. This means you need to be proactive and install the software ahead of time.

Positives of this approach?

  • Extremely effective.
  • Affordable.
  • Full contents of text messages are retrieved.
  • Large amount of cell phones are supported, including the popular models such as Android, BlackBerry, iPhone, Nokia, and more.

Negatives of this approach?

  • Can be difficult if not familiar with installing cell phone apps.
  • Software must be installed prior to message being deleted.
  • Requires a data connection such as 3G or Edge
  • May increase data fees if a large amount of text messages are sent on a daily basis.

There you go. Now you know how to retrieve deleted text messages using a couple different approaches. The next time someone asks you how to retrieve deleted text messages, you’ll know what options exist, and which one is the best for that particular situation.

Good luck!
