Can I Watch TV From My Computer? Yes, You Can

Watch TV From My Computer

Have you ever thought to yourself "It sure would be nice to watch TV from my computer" Well, it's not the province of the super rich or ultra nerds anymore. In fact watching TV on your computer is becoming more main stream all the time. Some, including software giant Microsoft feel it is the wave of the future. They're actually staked part of their future on it. Their new Vista operating system has features designed specifically to enable this sort of functionality.

That's great, but where do you get the content? I mean, you just can not have thousands of channels pumped into your computer straight from the Internet, can you? Well, actually you can. There are really a few ways to get TV on your computer. You can buy a TV tuner card. This basically turns your computer into a high tech VCR or personal video recorder (PVR – think TiVO) device. That's pretty darn cool, but there are a couple of downsides to the approach. First of all, as was pointed out earlier, there is a content question. Where do you get it?

With the TV tuner card method, you're limited to what is available with a terrestrial antenna, or you can hook up basic cable TV service. Anything beyond basic cable will not work using this method, because the content is encrypted by your cable provider. You need their proprietary cable box to decode the really cool channels, or pay per view events. So, while this method of watching TV on your computer is pretty neat, there are definitely limits with it.

You can use a pay per download service of watching movies on your computer, such as Cinemanow.com or Movielink.com. While they do offer a large amount of downloadable content, it's definitely not live TV. If you're looking for real live TV, you'll have to look elsewhere.

Another method is IPTV. TV content streamed straight over the internet to your computer or set top tuner box. There are two flavors of this. One is through a major service provider such as a cable, satellite or phone company. These are definitely capable of delivering a large amount of high quality content, but just because it's streamed over the Internet does not mean you'll just be pluggn 'in the net straight to your PC and watching reruns of Sienfeld. You are basically duplicating the cable set top box approach, except the method of content delivery is using IP packets instead of analog or other types of digital cable.

There's still another choice. You can watch streaming live TV directly on your computer or to a TV hooked up to your computer. Using one of several software based solutions, you can watch live TV shows such as sports, prime time network programming, reality TV, and moves. It's live, and even better there are thousands of channels available from all over the world. If you are looking to keep up on world events, or want …

Prospects for Software Testing Careers in the Future

Posted on Posted in computer, programming, technology

A software tester is an IT related professional whose function is to recover bugs or unexpected flaws in completed software applications prior to public release. These individuals are valuable team members whose role is to assist the software development team in missing faults or undesired behaviors in programs or applications.

Testers can save the developers time and money by discovering program flaws early, thereby avoiding the necessity of having to release patches or fixes down the road. And in the worst case scenario, early detection of critical bugs will prevent the need to rebuild the software application from the flawed code on up.

Some testers are third party contractors. The reason for this is to ensure that the tester is completely objective and fulfills their job to the best of their ability. Software testers perform standardized tests as well as customized tests that often were never considered by the designers, but that are logical from the perspective of the end-user.

Software is constantly evolving, and as such is becoming more and more complex. The programming languages ​​and coding schema are so intricate that software testing is becoming more critical over time. Additionally, the software testing industry is part of the general IT field, which itself is experiencing tremendous job growth. Job growth from 2008 to 2018 for software testing is predicted to grow at a much greater-than-average rate with an increase of 38%. Few fields offer as many carers with such a fantastic potential as Information Technology professionals and particularly that of testers.

The IT field is reliably new and testers' job descriptions are constantly being updated. No degree is necessary for some software testing professionals but certain characteristics and skills are required. The software tester who understands at least the most basic of software languages ​​such as C, C ++ and java will have an easier time hiding bugs and flaws. Knowledge of software programming languages ​​helps in understanding what parts of the code may be at fault. Software testers may also have a four-year university degree in programming, software design, or computer engineering, or they may be enrolled to learn on the job from suitable applicants.

The role of a tester in a company is a proactive one and requires excellent communication skills as well as a large amount of tact. Software testers must be able to communicate well both verbally and in writing, and communicate to both professionals in IT as well as those in charge of funding.

There are many skilled opportunities for software testers. With the correct mindset and personality, a career in software testing can be a fulfilling one. Software testing opportunities exist for both the individual with a degree and for the determined and interested individual willing to learn on the job and study to improve their marketable job skills. Most companies know that even with a Bachelor's degree in IT, much of the software tester's true job skills will be learned by doing. …

Technology And Child Education

Posted on Posted in computer, internet, programming, technology, website

Techno-Toddlers

When I was a child, I was very up-to-date on the latest technology. I watched Sesame Street, followed by Mr. Rogers Neighborhood. My home received all the channels available – three local channels, and two PBS stations. I surfed the available programming by going over to the television, taking the pliers off the top of the TV, gripping the pin and twisting (the plastic dial had broken off years before my birth). Telephone calls could have made on our large, black rotary phone. During fifth grade, I played Pong and thought I was really onto something. We got an Atari 400, and I experienced my first educational programming: Lemonade Stand, while was a very early version of Roller Coaster Tycoon. Nowadays, a four-year-old could probably program that game while watching the latest episode of Dora the Explorer and surfing the Internet for accompanying website games to develop his map skills.

Technology can be both helpful and harmful for your children. Let's look at some of the pros and cons of using technology with your kids:

Stimulation and Learning Toys

Computer games and toys that simulate computers can be very helpful for learning. Repetitive games that teach letters, numbers and reading can be great, and the graphics and music accompaning basic facts can help kids learn.

Be careful, however, not to let your child become over-stimulated by video-type toys. Reading books with each other is another great way to develop reading readiness, and playing with puzzles or basic toys is also good. You do not want your child to depend on flashing lights and buzzers in order to learn new skills.

Health Risks

Video and computer games have been linked to vision injury in children, as well as carpal tunnel syndrome. In addition, addiction to these games is a very real consensus. It is extremely important to set time limits on gaming. While your child may develop some killer small motor skills, he could have ruining the nerves in his hands at the same time. Keep an eye on him (and his fingers).

Predators on the Net

The Internet is a remarkable learning tool. Work together with your child to research anything of interest. Most children's programming also has websites with games and activities. There are also interactive sites where children build houses, care for pets, or submit writing.

Close parental supervision is of utmost importance when children are surfing the web. Chat rooms on kids' sites are often prowled by child predators. If your child has an email address, monitor it carefully for spam and sexual content. Kids are naturally curious, but can get into a lot of grown-up trouble quickly if left to their own devices online.

Cell Phones

My daughter came home from fourth grade yesterday, begging for a cell phone. Since her teenage brothers both have phones, I assumed she just wanted to act older than her age. Not the case at all – over half her class has cell phones. The kids are talking, and …
