When to Upgrade Your Office Computers

office computer upgradeThe IT industry is developing at never-seen speed, but the investment into new technologies to make office work easier and more efficient is something that most companies fail to award the necessary attention to. Many companies, no matter what industry they work in, are reluctant to recognize that, without a suitable and efficient park of office computers and with the necessary upgrades to office software and hardware remaining only promises, they, in fact, compromise the efficiency of their business activity.


It is nowadays a fact of life that if you use office computers, you need to upgrade, sometimes even completely replace them, so here is our short outline of the reasons to upgrade and signs that require immediate action.


Why Upgrade


Office computer upgrades are beneficial for a number of reasons – here are just a few:


  • Enhanced productivity – old hardware that is required to run new software applications will slow down considerably. The time required to open a document in a more advanced format or to send those documents to the printer will become longer and chances are that there are new and widely used formats that old computers are completely unable to open, making efficient work even more difficult – issues that new computers do not have;


  • Energy efficiency – new computers are able to function more efficiently while using less energy, thus increasing your company’s return on investment faster;


  • Security considerations – old computers are unable to accommodate the most modern defense software applications, making your corporate system more vulnerable to threats, so upgrades are absolutely essential to be able to carry out your business activity safely.


Signs That Tell You That You Need Upgrades


Besides the overall benefits outlined above, there are very obvious signs that your office computers are in desperate need of an upgrade:


  • Computers slow down – unbearably long processing time can be the result of a process or it can appear after you install some sort of application that breaks the camel’s back. In both cases, you need to carry out a detailed evaluation of the situation to be able to determine whether it is just one component of your computer that needs replacement such as the CPU or your network is so old that you need to replace the workstations;


  • Computers become noisy – computers tend to become noisier as they age and loud operation is a tell-tale sign that indicates failure. If you hear fans and hard drives struggle to work, start creating backups for the data on your office computers and prepare to buy new machines;


  • Frequent breakdowns – if your computers need repair all the time, you better replace them before repair costs exceed the value of the equipment.


The best way to upgrade your office computers without ruining your IT budget and without compromising the operations of your company is by thinking ahead and putting together an upgrade or replacement plan before a catastrophic failure happens. Ideally, upgrades are necessary every three or four years, but the period that your office computers can function safely and efficiently depends entirely on your line of business, so evaluate your computers regularly and implement an upgrade strategy based on commonsense – it is the best way.


Building an Industrial Computer Systems

Industrial Computer SystemBuilding an industrial computer system is a complex task that should be preceded by taking into consideration of all the factors that can influence the performance, the reliability and, last but not least, the costs of owning the system. There are probably as many different sets of decisive factors as there are companies, so what we are proposing here is a general outline of a few of the most frequently used viewpoints.

Application Type

Do you need to build a system for a production plant that uses high-precision manufacturing processes? Do you need your computers to be able to run industry-specific interfaces? These are all questions that will determine your choice of industrial computer hardware.

Industrial Computer Performance and Processing Needs

When it comes to performance, one of the most important specifications and usually the first that experts check is the performance of the processor (CPU). The processing power that your system requires depends on the type of industrial project that the computers will be used for and it will determine not only your choice of processor, but also the selection of other components such as the mother board.

The Environment

The location where you will use the workstations in your industrial system is also a very important factor to be considered when building a system. Dust and other particles floating in the air in the space the computers are placed in can – and will – harm conventional computers, so in industrial environments your computers need to use special cooling and ventilation components to be able to face these special challenges.

Vibrations and shocks are also frequent in industrial environments and your computer system must be designed with these factors in mind as well. If your computers will be placed in an environment prone to shocks, make sure you use only special computer hardware that has been designed to endure such harsh conditions.

Another factor that you need to pay attention to when building your system is the temperature range in the space your computers will be required to function in. Extremely high temperatures can cause overheating, while extreme lows promote the accumulation of moisture, both very harmful for computers, so again, make sure you use special, dedicated hardware in your system to make it resistant to extreme climate conditions.

Power Needs and Features

Is your power supply stable and reliable at all times? Would you feel safer and more relaxed knowing that you have a back-up in case of power fluctuations, blackouts and surges? If your answer is no to the first question and yes to the second, you may want to consider having suitable uninterrupted power supplies added to the system at least at key nodes.

Industrial computer systems are best built by professionals, but company owners and managers can answer the questions asked by these professionals only if they know exactly what they want and they are familiar with the challenges posed by their environments. Before you hire anyone to build a system for your industrial facility, assess the facility based on the above aspects – you will see that the collaboration with your IT specialist will become much more efficient that way.

Alternative Currencies to Bitcoin

Alt CoinSeveral other digital currencies are being used and traded in the market. After watching the enormous success of Bitcoin, many programmers decided to make their own Alternative Currencies, so it seems like everyday there is a new one. However here are nine different alternatives to Bitcoin that are now slowly coming in the limelight.

Litecoin: This is a digital currency based on cryptography that makes it similar to Bitcoin. Its value has experienced quite a dramatic rise recently. An open source peer-to-peer digital currency is often termed as Bitcoin’s spin-off. Its operations use Bitcoin’s protocol as the foundation, but Litecoin can be easily mined using the standard computers as it algorithm was created by Dr. Colin Percival to be used on different open source computers and operating systems.

Peercoin: It is another popular variant of Bitcoin. It promises its users with enhanced mining efficiency, better security and improved group mining. It is the fourth biggest alternative digital currency of Bitcoin and its market is growing with each passing day.

Namecoin: A cryptocurrency can work as a dispersed DNS. As Namecoin acts as the currency’s own DNS, it can operate outside of the internet and Icann (Internet Corporation for Assigned Names and Numbers) easily. The domain names and currency values are saved in the record of the block-chain that limits Namecoin’s total number to 21m. Each coin can be divided to around eight decimal points.

Feathercoin: Feathercoin is based on Litecoin and the mining difficulty of this currency is frequently adjusted. It makes regular updates to the software for adding new enhancements and features to it such as protections against forking and abuse in group mining that is one of the most serious concerns in group mining.

Primecoin: It is a cryptocurrency like the famous Bitcoin, but it employs an entirely separate mathematical procedure for mining that makes it different than Bitcoin. It does not rely on the Hashcash algorithm that is used by Bitcoin. Instead, it uses the long Cunningham strings for building value of the currency. Cunningham chains are sequences comprising of different prime numbers and have been named after AJC Cunningham, a renowned mathematician. The difficult level of Primecoin’s mining is higher than that of Bitcoin mining.

Novacoin: Novacoin is a peer-to-peer digital currency that integrates protections schemes in the currency’s core to deter abuse occurring in the mining groups. Its technical cap of around 2bn coins that is a larger value than the technical cap of the majority of the other currencies that tops out in millions and not billions.

Infinitecoin: It is yet another spin-off of Litecoin, but differs from its ancestor in two ways. First, its mining difficulty rate is adjusted quite frequently and more coins can be easily created in Infinitecoin. Currently, one can generate around 1142.86 times more coins as those created in Litecoin.

Megacoin: It was created during the end of 2013 and is in its growing phase currently. It comprises of 42m coins at the moment and each coin is valued at $0.50.

Quark coin: It is another digital currency that is in the infancy stage right now. It takes security issues very seriously and has employed nine different encryption grounds by making use of six dissimilar algorithms to enhance the network’s protection and security.

In addition to these nine popular substitutes of Bitcoin, there are myriads of other digital currencies that are being traded in the market. These include AlphaCoin, AnonCoin, BBQCoin, AmericanCoin, AndroidsTokens, BitGem, BitCar, AsicCoin, BottleCaps, CopperLark, CHNCoin, CryptogenicBullion, CryptoBuck, CasinoCoin, CopperBars, ColossusCoins, CryptogenicBullion, CopperLark, CraftCoin, ByteCoin and CryptoBuck. The reason there are numerous altcoins is due to Bitcoin’s hefty price that makes it difficult for people to buy them directly. This is why new and more altcoins are being created so that people could have more affordable and convenient options of digital currencies.

Types of Bitcoin Mining

bitcoin miningOne of the most common questions that we have been asked at bitcoin meetups is, “What is bitcoin mining?” Well, here is a short guide to get you started. Keep in mind, at this point it is very difficult to make money mining bitcoins. That being said, you might want to try just for fun.

There are basically two main kinds of mining: solo and pool. Solo mining refers to practicing mining on your own. You don’t have help or assistance offered by anyone in this mining category. Though, it is a private and peaceful method and can help you earn a reward of a whopping 25 Bitcoins, it is indeed the harder of the two methods. It can take a solo miner numerous weeks, months or even years in earning actual Bitcoins as they are relying on their own hardware to accomplish the goal.

On the other hand, pool mining is a better and more convenient method of practicing mining. Using this method, you sign up with an account offered by any company that carries out groups of miners working together, and adding all their computational power, to solve blocks. Such companies have their own hardware and software and group together mining efforts and skills of several miners’ computers. Every miner gets a proportional amount of Bitcoins depending on how much computational power they provided to the pool. However, this is a better option for you as it increases your likelihood of earning more Bitcoins.

If you are interested in knowing more about mining pools a simple Google search will put you in the right direction.

There are mainly three categories of hardware for miners: FPGAs, ASICs and GPUs.

FPGA refers to Field Programmable Gate Array, which is an incorporated circuit that needs to undergo configuration after it is built. It allows a hardware manufacturer in getting a large volume of chips that can be customized for mining before they are placed in the equipment. Due to their customizable features, they help you mine better than GPUs and CPUs.

ASIC refers to Application Specific Integrated Circuits. They are specifically created for one purpose: mining Bitcoins at an escalating speed without consuming a lot of power. Due to their excellent speed and low consumption of power, these chips are quite costly. Their speed ranges from 5 to 500 Gigahashes per second, which is a huge amount.

GPU and CPU mining refers to mining using your own computer. This is an extremely slow type of mining as your computer does not have enough power and speed to practice mining at an increasingly fast pace. Adding in graphic hardware in your computer can increase the Bitcoin hash rate using your CPU. This card consists of graphical processing units (GPUs) that are created for enormous mathematical lifting that helps them calculate complex polygons. The two major vendors of GPUs are NVidia and ATI. These high ends are pricey but help you practice CPU mining expediently and at a good pace too.

You can choose any of these methods, which work best for you. Another issue you need to consider is whether you should buy your own rig or rent one. If you are a beginner miner, it is wise to rent a rig at first so you can find out how good you are at Bitcoin mining. Once you become an expert at it, you can purchase your own rig, as it will become an affordable option at that time. You won’t have any time constraints and would be able to use it at any time you want.
