Since the time that computers became mainstream, consumers have been looking for ways to speed them up. Whether you’re a business user or a regular PC user, you’d probably like to know how to clean up your machine and get it working better and faster.

It can be very irritating to see that you are running out of disk space. Instead of having to decide … Read More

Do Computer Scientists Use Math?

May 3, 2020 | computer | No Comments

Recently a student, “James”, asked if it was possible to him to work in the computer field, even if he doesn’t like math and says he is not good at it.

The short answer: yes. The longer answer? Yes and no.

There is a huge opportunity for development of all kinds of software and hardware that doesn’t require mathematics, per se. Fields like software/app design and UX (user experience) quality assurance require understanding of the language involved and how the software interacts with the overall hardware, but not deep mathematics.

So James can certainly make a good career working with computers without knowing his epsilons and deltas.

But will math be useful?

Some areas – like some of the formulas we memorize in calculus class – will not be useful. But others, like discrete mathematics – will prove very useful to James: they will teach him concrete concepts he can … Read More

“Those who say it can’t be done need to get out of the way of those that are doing it.” Unknown

The entrepreneur of today’s world can be compared to the legendary Don Quixote – chasing windmills in search of great fortune.

The entrepreneurial journey I would like to share with you in this article might be a bit of a surprise. I find it remarkable yet I have barely seen it mentioned in the press over the years.

Imagine the following scenario. The year is 1983. You are a college freshman at The University of Texas in Austin, sitting in your dorm room playing around on your computer.

1983. Pre-Internet. Pre-computers-on-every-desk, in-every-room-of-the-house. These were the days of PONG, where very few people sat around playing with personal computers. (If you don’t know what PONG is, ask someone a lot older than you.)

Back to your dorm room. You are … Read More

Most Popular Computer Games Ever

May 3, 2020 | computer | No Comments

While many enjoy playing on a console, there are also many who see the benefits of playing on a gaming desktop. Some are of the opinion that real gaming can only happen on a computer rather than a console. With this type of unit, you are able to change many things affecting the experience of your software, whereas on a console everything is fixed, immovable, and unchangeable. Computer games are intriguing and many are as entertaining as any console program. To give you an idea, here are a few of the most popular computer games ever for a gaming desktop:

StarCraft

The military strategy of StarCraft has a large following of fans. StarCraft has sold over 11 million copies since its release date in 1998. Developed by Blizzard Entertainment this real-time strategy game has an award winning sequel that those with a gaming desktop love to play.

Computer Recycling – The Importance

May 3, 2020 | computer | No Comments

Electronics are becoming more and more easy to use, causing them to become in high demand. There are multiple places to purchase a new computer. With such a demand for new, smart, easier to use computers poses the question, “what do I do with my old computer?” Old computers to be taken the Goodwill or donated to a school for computer education. Our high speed internet is to much for these oldies. Luckily new technology has given birth to Computer Recycling Companies, and has given them the ability to recycle computers in order to save the environment from harmful waste from old, rotten computers.

One of the many Computer Recycling Centers is Best Buy. They now have streamed on their web site and on their commercials that they will take in any old computer and/or laptop for a $10 processing fee then will give you a $10 gift card. Just … Read More

Modern day computer hardware is getting quite robust, and there is about 10 times the computing power in a smart phone as was used to fly the first Space Shuttle, maybe more. Still, when it comes to operating today’s aircraft simulators the computer hardware is intense, and these simulators can cost a ton of money. Because they cost so much the time to use them becomes very valuable, therefore most airlines only use them as required to check out their pilots, or train them for certification on the next aircraft that pilot needs to fly so he or she can get their type rating and satisfactorily prove they are safe.

The other day, I was speaking with an expert in computer online gaming communities, Troy Laclaire, about the use of simulators in aviation, and how great these tools were for complying with safety standards and preventing mistakes in the real … Read More

In the field of computer forensics, as in the field of law, procedures in civil cases differ somewhat from those in criminal cases. The collection of data and presentation of evidence may be held to different standards, the process of data collection and imaging can be quite different, and the consequences of the case may have very different impacts.

A couple of quick definitions may be in order. Criminal law deals with offenses against the state – the prosecution of a person accused of breaking a law. Such offenses may of course include crimes against a person. A government body, or the representative of a government body accuses the person of having committed the offense, and the resources of the state are brought to bear against the accused. Guilty outcomes can result in fines, probation, incarceration, or even death.

Civil law covers everything else, such as violations of contracts and … Read More

Business owners, board members and managers must depend upon accurate and accessible information to make important decisions. The theft, damage or unauthorized disclosure of an organization’s mission critical information can be a disaster. A company can be crippled or forced out of business if it’s deprived of the data needed to function.

The world is in the middle of a cybercrime wave. The losses are huge. The total dollar amount exceeds that of the illegal global drug trade. Crimes that target an organization’s confidential information are low-risk and high-return. Data breaches are hard to prevent and difficult to prosecute.

Cybercriminals are constantly on the prowl looking for vulnerabilities to exploit. Thousands of computer networks, mobile electronic devices and personal computers are compromised every day. When hackers and crackers discover vulnerabilities they will exploit the weaknesses and attack for nefarious purposes.

A wise owner, manager or board member would want to … Read More

Your Computer Can’t Keep Time

May 3, 2020 | computer | No Comments

A computer needs a certain amount of information to operate; for example, the date and time, the amount of memory installed, the number of drives and their configuration, and so on. In the early days of computers, either the user typed in this information each time the computer started, or it was set using DIP switches and jumpers. Today, computers store this information in a CMOS chip that uses a small battery to retain the information when the computer is shut off.

CMOS (complementary metal oxide semiconductor) is type of chip that consumes very little power; therefore, while the computer is turned off, the battery discharges very slowly. But the battery will totally discharge if you leave your computer turned off for a year or so. Even if you turn your computer on every day, the battery is designed to last only a couple of years. Occasionally a battery will … Read More

Protecting your computer against hacking is different from protecting it against viruses that you accidentally or unknowingly invite into your computer that then cause damage in one form or another. Anti-hack is about protecting your computer against external entities that are deliberately trying to get into your computer to cause damage and to steal from you – or cause damage. Viruses are impersonal and hacking is personal.

Anti-Hack software is now out there for sale in addition to anti-virus software. These products protect you in ways that anti-virus software does not. Following are some examples.

DoS (Denial of Service) Attacks:

DoS attacks occur when too much traffic is directed to your company website at once. The web server essentially ‘chokes’ on the amount of traffic trying to squeeze into it’s network hardware. Attack scripts are easily downloadable and you do not need to be an experienced engineer to launch an … Read More
