Green At Work

Comments Off on Green At Work


22 April is earth day. It is time to think about how you can lower your carbon footprint at work. Here are some green practices that you can adopt to do so.

1. Computers are the Culprits:

Even in standby or hibernate modes computers use energy. To reduce energy consumption by 60 to 70%, set your computer to sleep mode when not in use.

Green Fact: Almost two-thirds of the energy used by a computer is for the monitor, so turn it off when not in use.

2. Disconnect to Stop the Drain:

Laptop and mobile phone charger draw energy (up to 95%) when they are plugged in even if they are not attached to the device, so disconnect chargers when not in use.

Green Fact: Switching off cell phones while charging uses half the power.

3. Lose the Paper Trail

Print with discretion; use soft copies whenever, wherever possible. Install a duplex printer (which can print on both sides), to halve paper consumption and reduce energy consumption by almost 25%. Designate a recycle bin for used paper.

Green Fact: Fax-modems allow document to be sent directly from a computer without requiring a printed hard copy.

4. Go Light on the Lighting

Lighting constitutes 29% of office energy costs, so turn off lights whenever possible to lower bills and energy. Install sensor activated lights especially in seldom or periodically used areas.

Green Fact: Energy saver light bulbs can save up to 50% on lighting costs and energy.

5. Recycle, Refill & Reuse

Opt for refillable printer cartridges and stationery made from recycled materials.

Green Fact: Avoid using paper and Styrofoam cutlery and crockery; use reusable ones.

Google Stats, Fox News and Pakistan

Comments Off on Google Stats, Fox News and Pakistan

Google has recently released its stats according which Pakistan has topped the list of searching pornographic matter through Google. The article was published and played up by FOX News in the wake of tarnishing the image of the country. The channel did not bother to take the version of Pakistani authorities but they just highlighted the fact on the basis of statistical data.

The article not only refers to stats but it highlights other things along with it. The writer on its own advised her reader to change the name of our country. The article also emphasize on the extremist elements existing in our country. This kind of journalism has always worked against Pakistan and such slanted act should always be played down.

There are loopholes in every society and system. Read the rest of this entry »

Possible Ban on Import of Used Computers

Multinational brand vendors are pressuring the government to ban the import of used computers and IT accessories. The Ministry of Information Technology (MoIT) is considering the proposal presented by these companies and other interest groups. The government’s decision to seek proposals has created discontent among second-hand/used computer users and sellers. The decision has been largely criticized as “a timid and anti-poor policy of the federal government”, as  reported by the Business Recorder. The paper added that retailers expressed fears that the currently increasing rate of IT literacy would begin to drop if the ban were to take place.

The newspaper reported that a used computer system is imported at 15 to 20 US dollars, while a new one costs around 350 to 400 US dollars. Pakistan imports – mainly from UK and the US, about 0.75 million used computer annually, which satisfy over 90 percent users of middle and lower class societies. Whereas, new computer capture a very small market share, according to retailers, there are about 35m000 shops selling second-hand computer across the country and imposing this ban is likely to put them out of the business.

On the other hand, adviser to Prime Minister for IT Sardar Latif Khosa said that there is no proposal under consideration at any governmental level to ban import of used computer as such measures would deprive common man from a personal computer, especially our students.

But we know our ministers’, adviser’s and executive’s statement are most of time false. They imposed the decision on the public later on but before it they always deny it so that public may not offensive. We need to see by implementation of this ban how many people will suffer. Business is already not in good position in Pakistan while type of steps are very bad on this situation. Our student can’t afford expensive devices and computer.

There is clearly and a real debate in the country because it does have real implications for economic, environmental and technological choices for ordinary Pakistanis.

Difference Between Ubuntu and Fedora

Ubuntu and Fedora are two distributions of Linux that are being distributed for free as open source software.

Fedora is a very popular linux distribution for desktops but it has been superseded by the meteoric rise of Ubuntu due to its user friendly interfaces. Fedora uses the “Red Hat” style, using RPM packages. RPMs are less standardized, so package breakage is more common. Also, RPMs cannot track their dependencies automatically, so you will experience “RPM hell” easily if you are not careful.

Ubuntu aims to make it easier to switch to a Linux based system for ordinary PC users with minimal problems. It also minimizes the need for typing into a command prompt and moves the majority of operations into a graphical interface like the Synaptic package manager. Ubuntu uses the “Debian” style, with DEB packages.

Although both are linux but Ubuntu and Fedora differ mainly in their package management methods. These are similar but incompatible with each other.

Installation: This is a little bit less important but might impact users is the installer.

Ubuntu has a very small installer as it does not come with a lot of packages. After installation, it prompts the user to check online for additional packages that might be needed for the OS to run at optimum or just any package that the user might want or need.

Fedora, on the other hand,  installers often have a lot of packages that you can choose from during installation, meaning bigger file sizes for the installer itself.

Summary:

  1. Fedora is based on Red Hat.
    while Ubuntu is based on Debian
  2. Ubuntu is a more popular linux distribution than Fedora.
  3. Ubuntu is easier for beginners to learn as compare to Fedora.
  4. Ubuntu uses DEB packages.
    while Fedora uses RPM packages and are incompatible with each other.
  5. Fedora installers often have a lot of packages while Ubuntu only has a minimal amount and downloads the rest from the internet.
  6. It is easier to find packages for servers with Fedora than with Ubuntu.
  7. It’s easier to install proprietary software in Ubuntu than with Fedora.
  8. Ubantu has friendly user interface. It comes with necessary sofwares to work as desktop OS.
  9. Fedora Core is the new version of Red Hat Linux. It is used for server purpose. It has great support also. RedHat is version used for server purposes. It is not that use friendly like Ubuntu.

Globalization – Journey Towards End

Comments Off on Globalization – Journey Towards End

Globalization is a complex phenomenon but undying reality. It neither need any introduction nor pertain a universal definition. But the fact of matter is it really exists and it has brought us in the historic age of transformation. Nations and world has been transformed to a wired planet through which you can enjoy the power of information.

Information Technology (IT) is a driving factor in the process of globalization. Improvements in the early 1990s in computer hardware, software, and telecommunications have caused widespread improvements in access to information and economic potential. These advances have facilitated efficiency gains in all sectors of the economy. IT provides the communication network that facilitates the expansion of products, ideas, and resources among nations and among people regardless of geographic location. Creating efficient and effective channels to exchange information, IT has been the catalyst for global integration.

In Globalization process, Information and communication technologies (ICTs) have been implicated in the structuring and restructuring of human social relations. The power to communicate has been one of the greatest achievements by human beings. Since, the development of the electrical telegraph and the telephone in the late 1800s marked a qualitative shift in the scope and power of ICTs, however. The new electrical communication systems brought disparate regions and peoples into an unprecedented, increasingly synchronous global network of information, trade, finance, and culture.

Online Advertising and Year 2010

Millions of new pages of content are being created every day and the vast majority is created by the individual publisher, but the advertising inventory is growing at massive multiples to the actual demand. With this, publishers will need to find new ways to be found and advertisers will need to find innovative ways to get in front of this micro created content. Here are some online advertising trends for 2010.

Advertising Marketplaces
These directories, such as our own AdvertiseSpace marketplace, will sprout up out of need for advertisers to find grouped niches that meet their needs and don’t have the time to scour the entire web looking for great sites to market their products on.

Social Media Advertising
We saw the birth of Twitter Advertising in 09 with companies like Sponsored Tweets and Ad.ly. In 2010 expect to see tons more advertising in your twitter feeds. Facebook and MySpace advertising also grew in ‘09 with their self serve create your own banner, platforms and for this year expect more growth and hopefully some innovations with the tools.

Indy Publisher Advertising
Major advertisers are going to seek our smaller independent ‘voices’ in lieu of massive publishers to return to grass roots. This will be a major shift in 2010 as big percentages of ad dollars will shift to the little guy.

Smart phone Advertising
Advertising within other people apps. You can run standard banners within iphone apps and there are already a ton of iphone app ad networks. iphone is the clear choice right now, with Android a close 2nd and Blackberries’ a distant 3rd. AdMob help show everyone the potential value in this model with its acquisition by Google for 750 million.

Advertising Exchanges
There is tons of buzz lately about Exchanges, but they are not new, and some view as worse than general ad networks with a higher barrier to entry and most publishers fear them because they make inventory even more price sensitive. They are good for advertisers and publishers with billions of remnant inventory and nothing to lose. AdExchanger is a great blog to read more about these, but they are obviously a little biased.

Decline in Ad Networks
2010 will be the year that publishers stand up and realize that Ad Networks having been taking advantages of them for far too long, with low fill rates, crappy ads and terrible payouts. Publishers will take control over their own inventory and demand higher rates.

Remnant Optimization
Publishers are going to demand more for their un-sold inventory and use more remnant inventory optimizing tools. These tools basically scroll through all the ad networks and find the highest paying banner for the open ad spot. 2 of the biggest ones are The Rubicon Project and Pubmatic.

Total Impact Measurements
Advertisers will continue to demand better brand engagement metrics besides the old standard impressions and clicks, measuring conversations and overall impact of advertising campaigns.

Application Advertising
Not advertising within an app, but actually building your own app as an advertising mechanism. Hey when someone is playing a game based on your brand, you can’t get more interactive than that? (Except actually using your real product

Demand Side Platforms
Everyone is also raving about DSP right now too, which is demand side platforms or even publishing. Some agencies are grouping together to have their own pool of ads to buy from. This is bad news for publishers. Basically it is media buyers saying, your content is crap and I think I could do better myself, or I just want to control the price market myself by creating my own exchange.

PTA Issues Show Cause Notices to Mobile Operators

Comments Off on PTA Issues Show Cause Notices to Mobile Operators

On the basis of recently concluded Quality of Service (QoS) survey of mobile phone operators, Pakistan Telecommunication Authority (PTA) has issued show cause notices to five mobile phone operators of Pakistan. These results were shared with the mobile phone companies along with instructions to improve their services quality. A reasonable time was also given to them, so that they can improve their network performance. However, it was found that all mobile operators failed to achieve the desired results. As a result PTA issued show cause notices to all mobile companies for failing to maintain the quality as per the license conditions.

This survey include quality of voice and SMS in 14 cities of Pakistan, AJ&K and northern areas including all major highways. This exercise has been conducted by PTA’s enforcement teams with the latest automated QoS equipment. PTA has been conducting this survey throughout the last year and shared results of first three quarters with the operators with directions to improve their services. The final comprehensive survey was conducted in the fourth quarter of 2009.

While talking about survey results, Chairman PTA said that ensuring provision of quality services to the telecom consumers has always been a priority of PTA. The objective of conducting QoS survey is to ensure that the telecom customers are being provided with top quality services. It may be noted that every year PTA defines its targets and goals where QoS survey of all services remains one of the major activities. The aim is to ensure that the telecom companies provide quality services as per the license conditions and instructions of PTA.
