Virtualization Explained

admin — Sat, 28 Apr 2012 17:00:43 +0000

What is Virtualization?

Virtualization is the creation of a virtual (rather than actual) version of something, such as an operating system, a storage device or network resources. For example you can run a virtual Windows operating system within an actual Linux system, thereby giving you two working systems on one set of hardware. This type of approach allows you to centralise the management of your network.

So what are the Advantages?

Less hardware is required to run the same amount of software, therefore saving in hardware costs. You could happily run all your applications on one server while running four virtual servers inside it performing other roles.
Data recovery is simplified. If your virtual server becomes corrupted then you just delete it and restore from a virtual backup. There is no need to restore the system from scratch and then restore from a backup. This allows the system to be recovered in a matter of minutes.

Virtualization allows you to test different software configurations on different platforms before you deploy it. This allows you to tinker to your hearts content with configurations without the possibility of damaging the existing network.
Reduces energy consumption. You are running less computer hardware to do the same amount of work.
Improved system reliability and security. Virtualization of systems helps prevent crashes due to memory corruption caused by software like device drivers.

So what are the Disadvantages?

You can get magnified physical failures. For instance if your main hard drive (or raid configuration) containing all your physical and virtual data goes down you would have to restore all your servers (physical and virtual).
Virtualization requires more memory and processing power. This would need to be factored into any virtualization strategy.
Training. Network administrators might not have the skills necessary to administer a virtual environment and would have to be trained.
Complex troubleshooting when things don’t work. Is there a issue with the virtual machine or some other problem?

Virtual Software choices

There is a multitude of companies offering their own flavour of virtual software ranging from the simple to the complex. The main competers are detailed below:

VMWare

Oracle Virtualbox (I use this software for my own systems)

Microsoft Hyper V

Citrix Xen Software

Overview

Virtualization is here and it is here to stay. It makes administering a network easier by centralising the management while reducing energy and hardware costs. Yes it also has its drawbacks but these are far outweighed by the positives.

Why Buy Genuine Ink Cartridges?

admin — Sat, 28 Apr 2012 17:00:43 +0000

Genuine ink cartridges for Canon, Lexmark, and other premium brands are made easily available in various computer and book stores and even on Web-based stores, to help your printer perform the best printing job all the time. Original cartridges will always give you the most efficient and best quality output.

Original cartridges passed through the quality control of the company that made your printer. They know what to look for in their products to make sure it works perfectly with their machines. As a result, it prevents you from wasting time, paper and ink when printing documents and images. Just in case you were unfortunate to purchase a cartridge that fails to function with your printer, you can most probably solve the printing problem through the troubleshooting steps conveniently provided in the program you’ve initially installed before you first used your printer.

Printer manufacturers offer easy-to-follow instructions that are handy for their users when any problem arises. FAQs and step-by-step information on how to remedy printing errors would be the initial suggestions. If these still don’t work, you can immediately call the customer hotline number of the manufacturer or its accredited service center in your locality. In case you really can’t get your printer to do its job, you can have the manufacturer or the service center check and repair it, if necessary.

Using only genuine ink cartridges for Canon, HP and other printers also ensures that your equipment warranty will be honored by the manufacturer or the service center. The manufacturer always does what it promises in the warranty only if you’ve used products that they’ve made specifically for the equipment you bought from them. There are many cases where consumers can’t have their printers fixed, because they used a part or accessory that’s not recognized by the manufacturer and that’s apparently the cause of the problem. Consumers are then usually stuck with no other option but buy a totally new printer.

The prices of original cartridges may make you hesitant to buy them. But if you’ll take into consideration in your expenses the paper, ink and time that you’ll waste in having a problematic cartridge, you might realize that you’ll just end up paying the same amount if you’ve purchased an original one. You can also add to this the possibility of having to buy a new printer sooner than you should due to the damage the incompatible cartridge would cause.

Genuine ink cartridges for Canon, HP, Epson, and other top printers may really seem to be sold at a steep price. But when you look at it carefully, you’ll realize that they’re more efficient in terms of cost and time and gives you better work quality.

Canon genuine ink cartridges are available on the Thrifty Ink website at reasonable prices. If you’d like to save on your printer ink, check out their site today. Ink and toner products for other brands of equipment are also offered.

In business, it is important to go where your market is. Today, they are on Facebook, which is where you should be too.

Here are few of the reasons why you should be promoting your business here:

1. It is easy to use.

The first thing you need to do is to create an account in Facebook. You can create a profile account or a fan page. A profile account is normally created to connect with your family and friends. Fanpages, on the other hand are used to introduce and promote a business.

The pages maybe customized. You can do it yourself by uploading images that represents your business, as well as adding details and information about the company. This includes contact information and locations.

2. Building a network is easy.

You can start your network by connecting with your friends and families. This is a good way to make your products or services known. Soon, your friends’ friends and families’ friends will learn about the business. Continuous marketing efforts will help your business grow.

3. It reaches more people.

The internet has breached the barriers caused by distance. Because of that, the possible number of clients you are going to reach is indefinite. With custom Facebook fanpages, you do not have to place an ad on other advertising media, thus cutting down your marketing costs significantly.

4. It provides an easier way to communicate with your customers.

When a potential customer likes your page, he makes it possible for you to contact him. You can mention him in your page, thank him for following it and start a natural conversation. Interaction between you and your potential client is one of the reasons why Facebook is very effective. You cannot do that through other media. This allows them to send you feedback right away and you can respond to those feedbacks with ease.

5. It helps you build a more personal relationship with your clients.

Since you can communicate with them on a personal level, you can easily establish a more personal connection with your clients and customers as well. Most consumers appreciate this.

We Need Distributive Energy They Say – But Apparently Also Need the Centralized Cloud, Really?

admin — Thu, 26 Apr 2012 17:00:43 +0000

Sometimes I think we have too many computer engineers and too many computer scientists. Further, it seems we have too many academics which wish to redesign our society and civilization completely. They claim that they are smarter than everyone else, and they understand the mathematics of complexity and chaos. They explain to us that they can help us systematize the world so it will run more efficiently, and at optimum.

However, when I talk with these individuals it’s obvious they don’t exactly know what they’re talking about, nor do they even agree with each other. Much of their dialogue is based in hypocrisy, and that’s problematic for me. You see, I am a free-market thinker, and I understand that millions of consumers and businesses choosing what they want and who they wish to conduct business with is much better than the government controlling the entire game in their attempt to make it more efficient.

In many regards this entire argument goes back to the debate between communism, capitalism, and socialism. It has to do with freedom, liberty, and the pursuit of happiness, it has to do with what Milton Friedman called; the right to choose. Not long ago, I was discussing this with someone who said that they would rather have a bottom up society, than a top-down society. Why I ask; why not some of both where it makes sense.

If you will read Ludwig van Misses book “Bureaucracy,” you see that we do need to pool our resources and various levels of government to do the business of the people, and yet, that individual was very much a libertarian thinker and economic philosopher. Nevertheless, he explains his arguments quite well. It’s not that I am against the technocrats, or don’t wish to engage their philosophical arguments, it’s just that I see the hypocrisy of many of those who wish to reengineer all we are and all we’ve built into some type of new utopia, especially as they recommend things which go against their very words of wisdom they promote.

Okay so, I’d like to give you an example here. On one hand the academic environmentalists and their alternative energy theory would have us believe that we need a more “distributive energy” system in the United States of America. Then these same folks, along with the most brilliant mathematicians and computer scientists also tell us that we need to take all the computing in our society and move into the cloud. They tell us that this will be better, more efficient, and save energy. Really?

Those two concepts are completely diametrically opposed. First of all, it’s quite expensive, and not cost effective for every person to go and install small wind turbines, and solar panels in their homes. However, they argue that to build new power plants, that a lot of energy is lost in the transmission lines, and it costs quite a bit of money to build new transmission lines and upgrade our current system and infrastructure, and yet, if we don’t we’ll be sorry later.

Next, on the cloud computing front we see that big computer companies are busy building giant data centers everywhere, and they want to move all of this big data, along with all your personal data on your computer into these cloud data centers because it is more efficient they tell us, but is that information really safe in the cloud? You see, when the power plant goes down there are big blackouts, and therefore you go powerless. What happens if the cloud goes down?

Now then, if your solar panels at home go out, or your system is haywire, only you, one individual is severely affected by this, and at that point you are very happy to be hooked into the grid. Just as if your computer goes down and you lose all the data on your PC, laptop, or tablet, it would be nice to have a cloud computing backup system. But I would submit to you that either of these two theories to make things more efficient cannot stand alone. Therefore, redundancy is needed. Nevertheless, the technocrats will remind us that if something is engineered perfectly, it will never go out anyway, therefore you really only need one solution if the system is solid.

That’s fine, but as a hobbyist engineer, and having built things which are simple, and also complex, I can tell you that Murphy’s Law is just as real, and just as good as any theory that these brilliant scientific academic minds can come up with. What I’m saying to you is that their arguments are flawed, and hypocritical. Yes, both strategies in any complex system are worth discussing, but I’m not sure I trust the cloud, and I don’t trust the theory of distributive energy either.

Having one power plant power up large areas makes a lot of sense, and it works. The distributive energy folks need to admit that until their alternative energy systems can work at the optimum they promise and is shown to be the most efficient to the conservation of energy, uptime, and cost. Once it can be used at individual residences and businesses to power up all of their needs without disruption, then doesn’t make sense to go there yet. And once that is possible, we don’t need the grid, but right now we have the grid and it works. What works is always of value – which is an axiom hard to debate.

Now then let’s talk about personal tech devices, and the batteries which are inside of them. Most of the batteries are insufficient due to the cost of Ion-lithium batteries, and that really isn’t very good technology anyway, we must do better there.

Therefore, if more information is in the cloud, those batteries will not demand so much energy for the processing power of the individual device, therefore they will be more efficient. So you see, there are both good and bad in both of these theories, and it is nice to have backups, safety, and redundancy.

Let’s be careful when someone comes up with some futuristic utopian grand scheme of things to help our society run more efficiently, and when they do, let’s ask them to put up cost numbers and real figures to their brilliant mathematical equations attempting to prove themselves right. Indeed I hope you will please consider all this and think on it.

Versatile Programs for Making the Server Management Productive

admin — Thu, 26 Apr 2012 17:00:43 +0000

As businesses are relying on computers and latest technology tools it is very important to have some monitoring devices and tasks that can make the network up and smoothly running. In a small business network there may be two or more machines connected with each other linking with a server. Another important thing is that the server must be healthy at all the times to keep the business process smooth and fine.

For these purposes a proper server monitoring hardware is mainly required by every organization. These are handled by experienced and efficient engineers and also the installation of these is easy. Any person having some technical ‘know how’ can install these. They do not require very much IT support and they start to monitor the network and keep it up at all the times. Simultaneously its software also keeps the network safeguarded against different malicious and mischievous users who always try to enter the network to steal the business data. It is the duty of strong monitoring software to check the machines and network periodically and ensure the security of the business information.

The good point here is if the hardware or software programs stop working they send an alert to the server about this. Because your IT infrastructure is the back bone of the entire business process so it must not be disturbed by any irregularity or technical issue. While arranging the monitoring hardware or software priority must be to confirm that it supports the network for which it is being taken. Compatibility should be matched to the server as the performance depends on the right type of hardware. It is very crucial to proactively monitor the issue before it creates downtimes and may stop the process impacting the business.

The issues can take place at any location on the server like on the central processing unit or on the memory hence the monitor program should be intelligent enough to scan the root cause of the problem. Another thing that makes the server management strong is the comparison between the past reports with the new one by which the server performance productivity can be determined. The reports generated by it should be in good formats and can be formed in the graphical form if required. The alerts must be proactive to send the information to the user before it harms the process. With all these things there are various benefits to have these programs may be again discussed in the next article.

What Is a Deep Cycle Battery?

admin — Thu, 26 Apr 2012 17:00:43 +0000

We are living in a day and age where some people have still never heard the term, deep cycle battery, despite the increasing awareness on working towards an eco friendly world. If you own or operate a golf cart or a boat however, you likely have at least heard the term before. They are commonly used in a wide range of devices today, however they are being used more and more often as the world becomes more eco friendly. trojan batteries are perhaps among the most common brand of them, so if you hear the term trojan battery or Trojan batteries, know they are often the same thing. There are many different Trojan battery types however, some of them are deep cycle batteries.

But what is a deep cycle battery? If you are a new RV owner or boat owner you will definitely want to learn more about these. These are commonly used on larger vehicles as they allow for the operation of heavy machinery that would need an extended load period. A Trojan battery that is a deep cycle battery would be a lead acid battery that offers a time release nature in its energy release, which contrasts significantly from a standard battery that offers a quick burst or energy discharge in a kick start way.

To understand deep cycle Trojan batteries you also need to know that there are different kinds of batteries, in much the same way you have different types of batteries for smaller electronic devices. A camera battery will be one kind of battery for example, while a remote control may require a smaller sized battery. The same concept applies to the Trojan battery lineup, as each different deep cycle battery will have a different application for it to be used.

Deep cycle batteries are meant to last a long time, because their very function is extended load use. Each battery type will last a different length of time. An RV deep cycle battery might last as long as 8 years or more, and a boat battery may only last 5 or 6 years. Although with good maintenance, deep cycle batteries can last a very long time. If you are buying that for a boat or RV, or something you wish to travel great distances in, you may also want to buy a Trojan battery that is a backup energy source. The last thing you need is to be stranded somewhere with no battery power, and a backup power source is always good to have, even though you hope to never have to use it.

Today, they are being used more and more frequently to operate solar powered devices. They are used in windmills and a wide range of solar powered devices as the world becomes more eco friendly. If you are looking at installing solar powered devices at your home or business, you may also need them and backup power supplies. As they are expected to become used more and more frequently in the future, you will find that buying your batteries online will save you a lot of money over paying retail price in a brick and mortar equipment and parts store.

What Are The Latest Developments In Technology?

admin — Tue, 24 Apr 2012 17:00:43 +0000

Advancements in technology occur every so often, thanks to the many gadgets that companies have now introduced. Whether it is in the business, societal, economic, medical, or communication field, there is always something new developed. Initially there was the computer but since the introduction of the internet, there has been a major escalation of technology in various arenas.

Even though the computer is still highly utilized, it has reduced in size and increased in functionality over the years. The desktop computer is, now, a one piece equipment with all the necessary gadgets included. There is no need for a tower, or CPU, because it all comes as one item. Soon, laptops will become a thing of the past as they give way to even smaller computers. The notebook that has been in the market for a few years has overshadowed the laptop. It is much smaller in size and can perform almost all the functions a laptop can. Recently introduced and creating quite a buzz is the tablet. This is yet another computer but smaller than the notebook. It has many features and is ideal to carry around. It is also stylishly designed so that it is striking and, it has all necessary protective elements.

Technology has also spread like wildfire through mobile phones. Leading companies Apple, Samsung, and HP, among others, have been competing to produce the best smartphones in the market. These cell phones not only perform regular telephone tasks but, they are technologically advanced to include computerized tasks. You can check your email, download music, play games, watch live TV and chat using your smartphone. Cell phones have certainly developed from the big, unsightly gadget to a super sleek, fashionable necessity.

Cameras, TV’s and Video games have also progressed technologically. There is much a camera can do besides taking still images. Through added technology, an individual can record videos using a camera, use facial recognition to ensure they take pictures of people from a distance and edit the pictures on the camera. When you consider television, a High Definition flat screen is the model to have now. The choices are widespread between LED, LCD, Plasma and DLP screens. They come in high resolution which makes the images much sharper and clearer. Technology has certainly changed TV viewing for all. Video games on the other hand continue to become more realistic as technology evolves. Microsoft, Sony and Nintendo remain major contenders in this field with new versions of the Xbox, PlayStation and Nintendo Wii, respectively. Be on the lookout for more as technology continues to advance.

And there is the application section that allows your potential clients to explore your offerings.

Vibration Transducer FAQ

admin — Tue, 24 Apr 2012 17:00:43 +0000

Q: Why calibrate a vibration transducer?

A: The pervasiveness of vibration and shock sensors continues to grow at an exponential rate. You can find these sensors everywhere, from aerospace labs and automotive test bays, to smart structures providing condition monitoring systems and active control. While these sensors continue to improve the performance of people, products and processes, this growing nation of test and automation is also growing a calibration liability. Considering the work involved with calibrating all these sensors, the question typically follows, “Do we really need to calibrate all these sensors?”

In most cases, the answer is “yes.” At sometime during a sensor’s product life cycle, either at time of manufacture or in test, a sensor must be calibrated. Simply answered, without calibration to a known acceleration standard, an accelerometer’s output cannot be absolutely verified and trusted. Another common response at this point is “Yes, I know it’s a good idea, but it takes time to calibrate and they always pass anyway…”

True, calibration takes time and a sensor will usually pass. However, strictly speaking, when an accelerometer fails calibration (due to mechanical or electrical problems), all scaled data measured by that sensor are invalid since the time of last valid calibration. Often it is impossible to tell exactly when a sensor has failed; therefore, test data taken during the full calibration interval must be revalidated or scrapped – wasting time and money. This is why the most critical and costly measurement applications require sensor calibration both immediately before and immediately after each test, to validate the data.

Q. What is driving implementation of automated calibration systems today?

A. Evolving domestic and international standards, along with growing inventories of accelerometers, have driven the demand for companies to invest in automated calibration systems. The cost of outsourcing calibration begins to justify a calibration system purchase return on investment (ROI) once a user crosses a hundred calibrations per year threshold. Additionally, uniform quality standards like ISO 9001 and ISO 17025 evolve as measurement technology advances. What was considered sufficient or state-of-the-art a decade ago in terms of quality doesn’t necessarily meet standards today. Not all calibration systems can pass these new standards. For example, total harmonic distortion measurement are now required in the ISO 16063-21 standard for vibration calibration.

As vibration and shock tests have become more ubiquitous and testing in general has become less expensive on a per channel basis, sensor inventories have grown to meet expanding channel count capabilities. All accelerometers need regular calibration, and automation speeds the process, lower cost and reduces uncertainty. Also significant is looming obsolescence. Many older calibration systems run only in DOS or early Windows versions, and computer hardware and software support is becoming nonexistent.

Q. What does the typical engineer need to know about accelerometer calibration related to the standards?

A. Standards can often be technically and administratively intimidating. The first thing an engineer can do to reduce anxiety associated with learning a new calibration standard is to speak with a professional from either his calibration service provider, or appropriate calibration system manufacturer. In most cases, calibration is covered broadly in the standards section on the control of measuring and test equipment. The calibration professional can help distill the essence of the standard into its technical and procedural components. It is remarkable how quickly a complicated standard can be tamed with a little bit of helpful advice. Armed with representative data plots, example procedures and recommended calibration intervals, a typical engineer can quickly and knowledgably present and recommend a course of action for his team to move through compliance and/or certification to the various technical and quality standards. For example, our application engineers routinely help new calibration customers with performance characterizations of our precision air-bearing calibration shaker as compared to the ISO16063-21 vibration calibration standard.

Q. What is meant by calibration “traceability” and why is it important?

A. Traceability is achieved through an unbroken link of reference calibrations back to a physical constant or national standard. In many cases this may be to the US National Institute of Standards (NIST) or in Europe to the UK National Physical Laboratory (NPL) or Germany’s national calibration authority (PTB). Traceability is important to ensure the validity of the overall calibration system results. Typical calibration techniques utilize a back-to-back or reference sensor with which the test accelerometer signal is compared. In calibrating the system reference accelerometer, each step in the link of these reference calibrations adds more uncertainty into the end calibration performed. To provide the lowest possible uncertainty in our customers’ calibration data, PCB Group is one of the few organizations that operates our own in-house laser interferometer and is accredited for primary calibration of accelerometers for test and reference use.

Q. Walk us through the typical process for calibrating an accelerometer.

A. Mount the accelerometer, press start, and print cal certificate. It really is that simple. Of course, the calibration user or technician must ensure that mounting surfaces of the sensor under test and the shaker reference are flat; have no nicks/burrs; and are free of residue. Proper strain relief of sensor cabling is also important. Additionally, a small amount of silicone grease at the sensor mounting interface will ensure proper contact and cleanly transfer vibration at higher frequencies for a smooth calibration curve. Problems with any of these situations can cause anomalies, or local resonance “glitches” in the calibration results.

Q. What are some specific challenges in calibrating accelerometers?

A. Transverse motion introduced by the excitation system or calibration shaker is a common source of error. Shakers are structures and have modes of vibration, just like anything else. With traditional mechanical flexure-based exciters, the undesired transverse motion of the shaker can be more than 100% more than the desired primary axis motion. This large cross-axis excitation motion, coupled with a small transverse sensitivity in accelerometers, can cause an undesirable “glitch” at certain frequencies in the calibration curve. Also costly and troublesome with older calibration systems, is the sheer amount of time it takes to perform calibration. Some older systems can take more than 10 minutes per axis – providing for lots of “hurry up and wait!” Finally, ISO 17025 compliance of the calibration certificate can be a challenge. While the standard sets specific guidelines for calibration certificates, interpretation of this can be overwhelming. Unfortunately, not all calibration software is compliant, nor can it be customized to meet these requirements.

Q. How often should a user calibrate?

A. Depends. Most manufacturers recommend annual accelerometer calibration, but how a sensor is used and specific test requirements often dictate proper calibration interval. Exceeding the accelerometer’s high or low temperature specifications, or if it is dropped, would be cause for recalibration. If the test object is safety critical or failure of the test object expensive, the calibration interval should be immediately before the test and immediately after the test. Such is the case with space flight hardware. On the other side, if the accelerometer is used only occasionally and there is a documented history of stability, the calibration interval might be extended to every 2 years.

Q. Is there any way I can make a quick accelerometer sensitivity check without doing a complete calibration?

A. A portable 1 g shaker can be used in non-critical applications to quickly check an accelerometer sensitivity at a single point fixed reference frequency. The 1g shaker is also useful for sending a 1g test signal end-to-end in multi channel systems to validate cable continuity and basic measurement channel scaling. It is important to remember, however, that the 1g shaker should not be considered a substitute for complete accelerometer calibration.

Q. Why are more modern calibration systems moving toward air-bearing shakers?

A. To use my kid’s slang, because “they rock.” Or conversely, they actually don’t rock. Air-bearing shakers virtually eliminate transverse motion inherent in traditional flexurebased shakers. In fact, most flexure-based shakers fail to meet ISO 16063-21 recommended transverse motion specification. Earlier generation air-bearing shakers had a number of drawbacks, including difficulty in mounting the sensor under test, and adjustment of support rubber bands, depending on accelerometer mass. Our new generation design addresses these drawbacks. By using a unique locking support and a Lorentz force lifting mechanism integral to the shaker, calibrating accelerometers of different sizes becomes fast and easy. This is in addition to other benefits, such as a self-centering bearing for easy operation, and electrical isolation for reduced noise floor.

Why Electronics and Gadgets Are Important to Our Everyday Lives

admin — Mon, 23 Apr 2012 00:55:43 +0000

The placid, laid-back lifestyle of yesteryear is gone and passed. Today’s society focuses on doing as much as you can in the little amount of time the day allots you. Because of this, technology, gadgets, and electronics run our everyday lives. Most people wouldn’t know what to do if they didn’t have smart phones to check their e-mails at any time and any place, nor would they be able to keep connected to family, friends, and coworkers while they are on-the-go. Laptops, iPods, netbooks, and cell phones are luxuries we use every single day without a second thought. It is apparent that we, as a society, rely a great deal on the newest gadgets and electronics to make our lives easier and more convenient.

The list of important gadgets and electronics reaches far beyond just those for keeping up communication. As we wake up every weekday morning, it is usually to the beeping of an alarm clock. Not many individuals would make it to work on time if they had to rely on their internal body clocks to wake them up precisely at the same time every morning. While you get ready for work, you may flip on the television to check out the morning’s news, or turn on the radio to listen to your favorite tunes while you get dressed and ready. Did you make a cup of coffee before you left your house for work? If so you have already used a number of different electronics and gadgets that just made your morning go smoother and easier than if you didn’t own these items.

Most individuals understand the importance of gadgets and electronics in our everyday life, but most don’t realize the scope at which it reaches. Technology affects all aspects of our lives. Without advancements in the medical field and electronics provided by doctors’ offices and hospitals, our life expectancy would not be near what it is today. MRI machines, many lifesaving invasive surgeries, and a number of preventative procedures would not be available if it was not for advancements in gadgets and electronics. At this point in our lives, these aspects go beyond just convenience and stretch to almost necessary for health and happiness.

Whether it’s the GPS you use to get to unfamiliar destinations, or the iPod you use to listen to your favorite music while working out, or even the wine refrigerator you use to store your amazing wine collection at the perfect temperature, these gadgets and electronics improve our quality of life to its highest extent making everyday living easy, convenient, and fun.
