Computers are slowly becoming common features in schools in Uganda. However, their impact on education is so far less than what could be expected from such powerful technology.
The use of Information Communication Technologies (ICT’s) in education, while being highly desirable from a number of standpoints, has never been an essential component of schooling. For this reason, the level of usage of ICTs has tended to vary from one school to the next.
There are many forms of computer applications in schools and computers are becoming powerful tools in the education setting. Despite this, recent research highlights teachers’ lack of skills and expertise with the new technologies as being the biggest deterrent.
ICT skills are increasingly becoming an important part of the general literacy skills of all teachers.
Teachers today need to be able to use computers and computer technologies effectively as a means of personal productivity, teaching tool and development of learners’ ICT skills.
But teacher education has been slow to respond to the technology changes in schools.
The need for all teachers to have ICT skills of some form cannot be overemphasised. Innovations in education are frequently avoided by the mainstream if current methodologies appear to be serving their purposes and there is no need for change.
Although there are growing pressures for teachers to embrace ICTs in classroom teaching, there is no mandated or specific need and this accounts for the reluctance and resistance on the part of teachers to change from traditional instructional processes with which they are familiar and comfortable with.
Technology is advancing rapidly. In such fields as multimedia and telecommunications, we can see many new products and services emerging with direct application in schools.
If we can graduate teachers who are familiar with the technologies to the point that they can plan, implement and evaluate instruction with them, we will be some way along the path to success.
There is a need to integrate computer technologies into teacher education programmes rather than to include ICT courses as independent entities.
Web's authority for assigning domain names ICANN on friday (11th/12/2009) approved a new address .post (dot post) for all global postal services. This will help postal services have their own address on the internet.
The managing rights of the .post top level domain name were granted to the UN's Universal Postal Union, which will set up the rules on which organisations the address could be attributed to. "People who access a .post site will immediately recognise it as belonging to a valid postal service or provider of postal services," said the UPU, calling it "a piece of real estate space on the Internet."
The .post domains are expected to be online by the second half of 2010 after the UPU and the Internet Corporation for Assigned Names and Numbers (ICANN) signed the agreement here
Although letters are commonly dubbed 'snail mail' in the Internet world, many national postal services have expanded their online presence and services in recent years, and play a key part in delivering e-commerce goods.
"Postal services will explore new frontiers and basically go where no postal services have gone before," UPU Director General Edouard Dayan promised.
When you type www.lwegatech.com into your browser's address bar, you expect nothing less than to be taken to lwegatech website. Chances are you're not giving much thought to the work being done in the background by the Domain Name System, or DNS.
Today, as part of ongoing effort to make the web faster, google launched a public DNS resolver called Google Public DNS, and the public has been invited to try it out.
Most of us aren't familiar with DNS because it's often handled automatically by our Internet Service Provider (ISP), but it provides an essential function for the web. You could think of it as the switchboard of the Internet, converting easy-to-remember domain names — e.g., www.google.com — into the unique Internet Protocol (IP) numbers — e.g., 220.127.116.11 — that computers use to communicate with one another.
The average Internet user ends up performing hundreds of DNS lookups each day, and some complex pages require multiple DNS lookups before they start loading. This can slow down the browsing experience.Research has shown that speed matters to Internet users, so over the past several months google engineers have been working to make improvements to the public DNS resolver to make users' web-surfing experiences faster, safer and more reliable thus the born of Google Public DNS.
Google Public DNS is a large set of DNS servers placed around the world. Interestingly, even though the number of caching DNS servers is apparently quite high, Google only uses two addresses for them: 18.104.22.168 and 22.214.171.124. (It looks like Google turned to Level3 to get some easy to remember addresses for this purpose, rather than use addresses out of their own, less-memorable address ranges.) The routing system simply delivers packets addressed to either address to the closest Google Public DNS location. So users in different places around the world will be talking to different instances of these addresses, making for faster round-trip times, which is important for good web surfing. This mechanism is called anycast.
Google uses clusters of servers at each of the anycast locations that collectively cache information, allowing requests to be rerouted from one server in the cluster to another. This provides better caching and thus better performance than simply distributing incoming DNS queries over a set of independently operating servers. Additionally, they've developed a system that can refresh information that is about to expire (all DNS records contain a "time to live" value), rather than removing stale information and then having to do a lengthy lookup when it's requested again by a user
If you're web-savvy and comfortable with changing your network settings, check out the Google Code Blog for detailed instructions and more information on how to set up Google Public DNS on your computer or router.
In an online statement issued by google. As people begin to use Google Public DNS,there's a plan to share what learnt with the broader web community and other DNS providers, to improve the browsing experience for Internet users globally. The goal of Google Public DNS is to benefit users worldwide while also helping the tens of thousands of DNS resolvers improve their services, ultimately making the web faster for everyone.
Unfortunately, despite the anycasting, advanced caching, and extensive security features, Google Public DNS is not the ideal DNS service for your primary dns server .it's in its experimental stage so my advise is to setup alternative DNS servers on your gateway.
More good things to come in 2010 that will help you save costs in all round activities. Himax Technologies announced the introduction of iCT (Infinity Color Technology), an innovative and proprietary image processing technology which enables significant power saving for TFT-LCD TVs and monitors, regardless of CCFL (Cold Cathode Fluorescent Lamp) or LED (Light-Emitting Diode) backlights, while enhancing image quality.
This technology developed by Himax Media solutions, a Himax subsidiary, the innovative iCT is a unique and cost-effective approach in optimizing power efficiency and image quality.
Power saving is an important concept in the flat panel display industry. For example, the California Energy Commission recently approved an energy efficiency standard for televisions. When the standard is implemented in 2011, new TVs sold in California should consume at least 33 percent less electricity. Likewise in China, the worlds largest TFT-LCD TV market, a similar energy-saving concept has been advocated at various events. However, with current power-saving technologies, there is always a conflict or trade-off among power-saving, image quality, and the costs to achieving both goals. To optimize energy efficiency, panel and system makers are aggressively seeking the best solution which has promised a bright future for green technologies.
TFT-LCD backlight, either CCFLs or LEDs, typically maintains a constant brightness at all times, regardless of the displayed images. One commonly-adopted technique in saving backlight power is CABC (Content Adaptive Backlight Control) which dynamically adjusts the backlight and contents. While this pure digital approach is able to save panel power, it inevitably leads to loss in gray scales while adjusting gamma curve and thus an undesired image quality. These side effects could be mitigated by using 10-bit or higher TFT-LCD panels, as adopted by a few Japanese tier one TV brands. However, higher bit TFT-LCD panel also leads to higher costs, which prevents wide adoption.
For the first time in world cup history 3D technology will be used to film atleast 25 of the world cup games.
FIFA confirmed that they will have 3D Cameras used to capture the games. Although it has no definite plans to broadcast the matches live in 3D, Fifa said it was a possibility and would be decided in "the coming months". Initially, it said, footage will also be shown at public events in seven cities around the world. The footage will also be packaged into a film.
Sony technology will be used to film the games, although the firm has not confirmed details of the specific technology it will use.
According to the review on 3D done by BBC news " The majority of existing 3D set-ups use two-camera systems to record images tailored specifically for the left and right eye of the viewer. Special polarised glasses are then used to view the image.
However, earlier this year, the Japanese firm unveiled a single-lens camera, which it said was especially suited for sporting events.
The camera takes a single image that is split by mirrors and recorded on two sensors. 3D technology has been used to capture special events before, such as the Queen's Coronation.
However, regular and widespread use of the technology is still in its infancy. Now, analysts believe the technology is on the cusp of becoming mainstream and believe the World Cup could play an important role in take-up of the technology.
"Global sporting events... are very important drivers of new technology, particularly in the TV market", said Tom Morrod, Senior Analyst at Screen Digest. he firm predicts there may be 13.6m 3D TV sets installed in Europe by 2013.
In 2008, the BBC broadcast the world's first live sporting event in 3D, beaming back an England vs. Scotland game from the Six Nations to a cinema in London. The corporation's director of London 2012, Roger Mosey, has said there are also plans to capture some of the Olympics in 3D.
In July this year, broadcaster Sky said that it would launch "the UK's first 3D channel" by 2010. It has also hinted that it may launch a sports channel which could include Premier League Football in 3D. The World Cup begins on the 11 June 2010.
