What Are Ruggedized Computers?

super ruggedized computerRuggedized computers (also known as “rugged computers”) are traditionally bought by military and industrial customers, warehouse workers, logistic workers, scientists, surveyors, but sometimes also by individual folks, for their personal use. The popularity of this type of computers increases every year.

So, what exactly is a ruggedized computer?

This type of computer is created to properly operate in harsh environments and difficult work conditions, whether we are talking about dust, moisture, vibrations, extreme temperature, or other factors that would make regular computers inoperable. These computers are equipped with safeguards against liquids and solid particles and they meet the standards for electromagnetic interference and the military standards for harsh environmental conditions. The certification of meeting these standards is the only proof of true ruggedness.

There are also semi-rugged computers, which are more resilient than your regular PC, but don’t have all the features of a ruggedized one.

Fully-ruggedized computers are built with durable, reinforced materials and protective casings. They are typically more expensive than regular computers, but they are more economical in the long run – this being the reason why their popularity increases even among users who do not work in rough conditions. A rugged computer can help you save money in time due to the fact that it is more durable, it beaks less often therefore there is less downtime, less lost data and productivity costs. These computers do not require to be reconfigured as often as regular computers and their long life cycle also means less need for training.

Choosing a ruggedized computer

A certain ruggedized computer can be a better or a worse choice, depending on your working conditions and habits.

Remember that owning such a computer should bring you flexibility and mobility when you work in a wide variety of weather conditions and environments, so it ultimately depends on you to determine your needs in order to choose the right fully-ruggedized or semi-ruggedized computer. The differences may be subtle, but they should not be neglected if you want the best value for your money.

Here are the standard features you should look for:

  • Resistance to particles

Most models are designed to operate without the use of fans; this way, dust and particles are significantly less likely to be collected.

  • Resistance to vibration and shock

Rugged computers are designed to endure drops and constant vibrations that would destroy keyboards and internal components of regular computers.

  • Resistance to water and moisture

Rugged computers are designed in such way that water and moisture are not hazardous to their electrical components.

  • Resistance to extreme temperatures

Most models can resist in desert conditions and arctic conditions

Extra-features drive up extra costs and they may include special heat pipe systems, trans-reflective screens, cable shielding and more.

Always consider a reliable brand that does more than encasing a regular product inside a heavy-duty enclosure. Also, remember that having a rugged computer doesn’t mean that you can neglect its proper transportation. Purchase a durable case or a bag for it; do not go for the stylish options, as they are often the most fragile.


Corporate Computer System Security

Computer SecurityThere are numerous features that corporate computer systems need to be able to function properly and there are lots of criteria as well that they need to fulfill to allow their owners to use them with maximum efficiency, security being one of the most important aspects. With today’s modern technologies such as cloud computing, wireless networks and smart devices, companies have access to more functionality, which enhances their performance, but only if they can protect their computer systems against external threats such as cyber-attacks and other security breaches.

In what follows, we would like to give a short outline of the potential threats you need to prepare for and to present a few methods to enhance the security of corporate computer systems, methods that make usage more streamlined and sensitive data safer.

Types of Threats You Are Faced With

Corporate computer systems enable companies to carry out their business activity and they also store sensitive, often vital information about that business activity such as financial reports, the list of business partners or industrial process, to mention just a few. One of the most dreaded threats is that of data and identity theft, this type of security breaches causing serious financial damage to businesses all over the world. Malicious intrusions, the contamination of the system with viruses and malwares is also among the major threats that can cause data loss by damaging not only software components, but hardware as well.

How to Implement a Successful Corporate Computer System Security Policy

The first thing to do when designing any kind of security system is to identify the possible weaknesses and threats. The computer system must be thoroughly tested for weaknesses and the types of risks it is exposed to must also be assessed. In some cases the risks are external such as malicious intrusions, but risks can come from inside the company as well, for example if employees lack information about safe system usage.

Once the threats are identified, the most suitable measures of protection can be designed. The system needs to be fortified to be able to ward off external attacks and the company’s stuff must receive suitable training that provides them with the knowledge to be able to use the system safely. All these must be included into the company’s cyber security policy, which should address not only the issue of external attacks and employee error, but also levels of authorization to access certain levels of the computer system, rules regarding the types of devices that can be connected to the system and protective measures against any other types of vulnerabilities. A recovery plan is also very important – breaches and failures can happen even in the case of highly secured corporate systems and you need measures that will help you not only to prevent these problems from happening, but also measures that will help you mitigate the damage in case they have happened.

Corporate computer system security is all about thorough analysis, the proper evaluation of the findings and the design of a comprehensive prevention and mitigation strategy. If your company relies on a computer system, make sure system security issues are properly addressed – it will allow your business to grow and function as safely as possible.

How And Why To Encrypt Your Phone

encrypting your phoneThere are many reasons you might want to encrypt your phone, but suffice to say it’s a good idea for most people. Nowadays our phones carry so much crucial data that it’s imperative that no one else has access.

M.K. Lords of Airbitz has written an excellent article on all manner of encryption. It includes a super-simple how to on how to encrypt your phone.
Here is an easy step by step from BGR on how to encrypt an Android.


  • Open up Settings.
  • Click on Security.
  • Find the option for phone storage encryption and enable it.
  • You’ll want to make sure your phone is plugged in during the encryption process, which takes around an hour to complete. Leave your phone alone while encryption is being enabled.
  • Once the process is finished, open up Settings again and check to see if there’s an “Encrypted” badge under the phone storage encryption option.

Should You Encrypt Your Phone

The FBI would prefer that you don’t actually encrypt your phone. Today, FBI director James Comey claims that unbreakable encryption is “an affront to the rule of law.” Yesterday, it was simply a way to safeguard your information against malware.

If you don’t want law enforcement to have access to your phone without your permission, you should definitely encrypt.


You find the following information under “attempts to unlock Google devices”:

For some other types of Android devices, Google can reset the passcodes when served with a search warrant and an order instructing them to assist law enforcement to extract data from the device. This process can be done by Google remotely and allows forensic examiners to view the contents of a device.

What this means is that Google may reset the phone’s passcode remotely if the proper legal paperwork is provided.

But, that is only possible of full-disk encryption is not enabled.

Really, the choice is up to you. If you have faith that giving the government and or criminals a back door to your primary communication device is not a problem, then don’t worry about it. If one the other hand, you worry about others having free access to all of your data, you should certainly encrypt.

You may remember the case of the Daily Mirror hacking a bunch of journalists’ phones.

The publisher of the Daily and Sunday Mirror faces further large payouts to future phone-hacking victims after losing its appeal to reduce the total of £1.2m awarded to eight victims including the actor Sadie Frost.

In this case, The Daily Mirror was clearly a bad actor acting illegally, but it is hard not to put some of the blame on the journalists who didn’t secure their own phones.

Remember, you can keep almost any attacker out of your phone simply by encrypting.

Bitcoin is known to be a decentralized digital currency, meaning that it is held digitally, without anyone controlling it. A Bitcoin wallet is the virtual equivalent of a bank account, a digital portfolio used for handling and safeguarding your bitcoins, as well as for initiating transactions that use Bitcoins and receiving digital money from others.


One of the main principal features that differentiate Bitcoin from conventional currencies is that your Bitcoins are stored in a digital portfolio or a wallet that anyone in the system can see. Your bitcoins are stored at your bitcoin address, but no one will know the address actually belongs to you as a physical person. Even so, you need the highest level of security to be able to safeguard your property, and the Airbitz platform is certainly one of your best options.


There are two types of Bitcoin wallets: software applications that you need to install on your computer or mobile wallets that come with the same features as the software, but offer more flexibility, more versatility and they are easier to use.

About Bitcoin Wallets

bitcoin walletAs you probably know by now, your wallet will be the place where you will store your bitcoins. Its main purpose will be to store the private keys of your Bitcoin addresses as well as taking record of all the transactions you will conduct. But in a more practical sense, you will use it to send, receive and store your bitcoins.

You don’t need to have only one wallet, you could see it more like a bank account and have one for spending or trading and one for saving or even one for traveling, one for home and one for long term savings, depending on your personal situation.

However there are different kind of wallets and they have their uses and purposes, so it’s very important that you know how each one of these operate so you can decide what’s better for your particular situation.

Remember that the bitcoins that you might have will be stored in a particular wallet, and if for any reason you loose it (let’s say you have it in your hard drive on your laptop), and for example your laptop falls from a cliff and the hard drive gets damage and becomes unrecoverable, your Bitcoins will be lost FOREVER, there will be no way of getting them back. So I believe it’s of high importance to decide where and how you will store your hard earned bitcoins and also strategies to back up them:

Bitcoin Desktop Wallets

(Armory, Hive (OS X), MultiBit (Windows, OS X and Linux), DarkWallet). These are some of the most popular Desktop wallets. As their name implies, these are wallets that are basically a piece of software that you download to your computer and keep it there.

With this software you can create bitcoin addresses to send and receive bitcoins and also store them.

They have the great advantage of being in your own computer, and thus they are very secure, the limitation is that if something happens to your hard drive, your computer gets lost, etc. You will lose them forever.

Also if you are, for example traveling, and you need bitcoin that is stored at your computer back home it will be impossible to retrieve them at the moment you need them.

However because of it’s safety and easy of use, the Desktop Wallet option is one of the most popular among bitcoin users.

Bitcoin Mobile Wallets

Here you can find the likes of Mycelium, Blockchain and Xapo. These wallets are pieces of software to be installed on your smartphone. As you might have already guessed, they are great to move around with bitcoin and even use the benefit of (NFC) Near Field Communication, which allows you to pay or get paid simply by tapping on the phone without the need of entering any information. However the obvious disadvantage of mobile wallets lies in its portability. If the smart phone is lost the bitcoin will be lost too.

Bitcoin Online Wallets

Here you can find Coinbase, Blockchain and Xapo. These wallets are held on the Internet by some third party. They have the great advantage of being always available and not being dependant of any single device in your control. You can access them from anywhere you can find an Internet connection and if your wallet provider is a reputable one they can be very secure.

Other benefit is that you can use them to duplicate (or backup) your addresses from mobile or desktop wallets.

However the great disadvantage of these wallets is that you involve a third party: the wallet provider. Someone else will be in control of your funds and somehow you will be disabling the whole purpose of bitcoin, bringing yourself back to centralization

Physical Wallets or Paper Wallets

As the name implies, these wallets are physical representation of your bitcoin addresses, they are a printed piece of paper with two QR codes, the first containing your Bitcoin address and the second one to encrypt your private key.

They have the great advantage of not depending on any online service or computer, thus they are immune to hacking. However they become a target for physical theft. In case a robber know this piece of paper is of any value, they could take it from you and relieve you from your bitcoins. They are not useful for receiving or sending bitcoin and must be seen more of a long-term storage solution for your bitcoin.

Hardware Wallets

These wallets are pieces of software stored on a physical device (like a USB pen drive) with some added security features; like password protections and some encryption. You can store your bitcoins in one of these devices with a little more safety than a normal USB pen drive. Some of them will even allow you to send and receive bitcoins securely by connecting them to an online device.

You must remember that no matter what wallet type you decide to use, they are all attached to your private key (password), you will need to enter this password to access your bitcoin, and currently there is no password recovery in Bitcoin, so if your password is lost your bitcoin will be lost too. It’s also very important to choose strong passwords to encrypt your wallet and reduce the possibility of hacking.

It’s a good practice to backup your wallets and make a printable version to keep with your valuable things. A desktop wallet can also be stored in a physical drive like a USB pen drive and be kept away from your Internet connected personal computer.

Buying and Selling of Bitcoins

buying bitcoinIn order to get started using bitcoin, you will need to have some bitcoins or at least a fraction of a bitcoin in your possession. To get the bitcoin you will either need to trade for it, buy it, or be given it. Purchasing bitcoins is a great place to start learning about bitcoin.

There are different ways of purchasing and selling Bitcoins. Look at the variety of exchanges you can opt for when buying or selling Bitcoins.

There are two main methods of selling and procuring Bitcoins: selling/ buying in person or buying/ selling online. Each of the two options has its own share of pros and cons.

Online Method

Selling and purchasing Bitcoins online is a commonly practiced method of trading Bitcoins. There are three different ways you can make use of when making a Bitcoin trade online.

Direct Trade

Websites that provide you platforms for online trading include Bittylicious and BitBargain in the U.K and LocalBitcoins and Coinbase in the U.S. You need to get registered as a Bitcoin seller for trading on these sites. You would need to verify your identity for registering yourself. Most of the markets practicing Bitcoin trading don’t demand an extensive verification from the buyers, but aren’t that lenient with the sellers. They consider your joining date on the website, require you to give scans of any two (utility) bills that display your complete address and name along with your photo ID (your driving license or passport.) if you aren’t comfortable giving your personal documents, then you would experience a lot of difficulty in selling Bitcoins online.

After your registration is complete, you can begin posting offers online that would signal that you plan to sell Bitcoins. The site will send you notifications alerting you when any buyer is interested in trading with you. After that, you and the buyer will be solely responsible for the transaction, but you will be using the site as a platform for completing the trade.

Bitcoins users in the U.S. who have their individual bank accounts should consider trading on Circle or Coinbase as these websites are user-friendly and help you trade easily.

Exchange Trades

Another way you can sell Bitcoins is by registering with an exchange online. You would need to confirm your identity. However, you won’t be required to work a lot for organizing a sale. These exchanges work as intermediaries that hold the funds of people trading on them. You need to put up ‘sell order’, state the amount and the currency type you want to sell as well as the per unit price of that currency you are planning on selling. That currency will be credited soon to the account in your name.

The downside to this method is that you would have to withdraw funds to the account in your bank if you want to sell Bitcoins for fiat money. If that exchange is experiencing problems with the banks it deals with or any liquidity issues, it might take an extravagant amount of time to get your funds. BTC-e and Mt. Gox are two exchanges that are notorious for such issues.

Therefore, it is imperative that you extensively research on different exchanges before using one to commit your funds. You could also make use of cryptocurrency exchange for changing Bitcoins for any other cryptocurrency. Though, it is not a commonly practiced tactic, but some Bitcoin traders exercise it.

While using any exchange, you would be required to pay some fee for using that exchange’s services. BTC-e has a flat fee of 0.2 percent. In addition to that, there is a limit on the volume of money that you can store on a certain exchange. This is why experts advise that you don’t store all your money (Bitcoins) on an exchange. It is best to store additional funds on any of your personal devices instead of keeping it on any exchange that has a risk of getting hacked.
