How Will the Telecoms Industry Respond to the Threat Posed by VoIP?

October 8th, 2008

One of the most important developments in the telecoms industry in recent times has been the development of mobile VoIP technology. Although still relatively early days for the mobile Voice over IP start-ups such as Truphone, it certainly seems they have the potential to mix things up in the telecoms industry. Some of the recent incumbent mobile operators’ actions seem testament to this fact with T-Mobile recently being forced to allow the use of Truphone over its network, having previously not allowed calls to Truphone alloted numbers.

Whilst a few industry commentators argue that as VoIP prices tend towards zero, this is making it a increasingly difficult industry to make any substantial profit in; the increasing prevalence of cut cost high speed broadband and has resulted in a huge increase in the availability of free Wi-Fi. As a result this is making mobile VoIP operators an increasingly attractive offer for consumers. The trend in the availability of new ’smart phones’ with the ability to run mobile VoIP client software, at ever reducing prices is also, it could be argued, creating a tipping point in the industry.

We have recently seen T-Mobile introduce their VoIP service called @home giving people the option of paying a single low monthly flat rate. However whilst the industry is finding customers uncomfortable about getting rid of their fixed phone line all together, mobile VoIP operators have no such issue to contend with. The seamless integration of mobile VoIP software into the functionality of mobile phones, as well as the falling cost of unlimited data phone packages has resulted in a predictably fast growth in the mobile VoIP industry.

At present it has been reported that there are 4 million VoIP subscribers in the UK, and the growth looks set to continue. How established mobile phone operators will take advantage of this growth is still unclear but the decision to force T Mobile to unblock calls to Truphone subscribers surely transmits a clear message that rather than try and resist the mobile VoIP operators, the long established industry monoliths must find a way of working with them.

One issue which may have an impact on the amount of subscribers of mobile VoIP is security, with many highly publicized stories highlighting the vulnerabilities in making calls using VoIP. Another problem to to confront is ‘VoIP phishing’ where people are convinced to part with their personal data voluntarily after falling for a thief’s lure. This is also indicative of other VoIP security issues where unscrupulous would be thieves can tamper with the caller ID making it appear as though they are calling from reputable financial institutions. Once such issues have been resolved and fears allayed it is likely that mobile VoIP will become will become much more integral to peoples lives as people take the opportunity to turn their mobiles into VoIP phones.

The Crowded Market of Gaming Notebooks

August 12th, 2008

Itwas not too long ago when only a few brands made gaming notebooks. In the past the small number of sales alleviated by the profit margins. These desirable notebook computers were just too expensive. They were basically the best laptops that the technology was able to offer at that time. Gaming laptops would get people thrilled about what’s to become standard in a few years but I do not believe they would buy laptops like this whilst be wary that the price is going to drop quickly. Sales will get better though now that well known companies are getting into the sector.

Compared to the tiny resellers these companies are aware that they can get even more profit.At the moment the profit margins on the majority of notebook computers are so marginal that this constitutes as an excellent chance to roll back the gross profits. With their bottomless marketing budgets I’m sure they can get anybody to buy laptops like these. Had I been a smaller reseller I would definitely be thinking of schemes to react to this form of competition. In my view the large companies will control the market trends. Local manufacturers can’t possibly leverage a brand name as the larger competitors could.

I guess its a joke that as it comes with the brand name they’re seamlessly though of as the best laptops. Still though, for the little small companies this could turn out to be positive. In my view being able to specify the components you require would be a deciding factor. These purchasers have the technical literacy and would decide which products are best. For a couple of customers specifications and statistics are more meaningful than design. Of course from the purchasers perspective, its a great thing. In the end it will drive prices down even further and make the premium technology even more attainable for everybody. Though I say that, I’m not really sure of my claims. New product launches should uphold premium prices. The global companies have already introduced their own gaming laptop range, so all we can do now is sit back and watch.

UPS Battery - Useful Protection for Your Office

June 26th, 2008

Just think of the hassle that you would half to go through if you had to redo all the work on your computer for that day because of a power failure. Everyone thinks that they are safe because they are connected to a surge protector but yet that means that when you loose power your computer still has a hard shut down and all it does is help stop a power surge to hit your computer.

Can you just imagine that you had a presentation on your computer that you were working on all day and forgot to save it? Then all of the sudden the power goes out from an electrical storm and you loose all that days’ hard work.

Just how would you get through the presentation if you had to sit down and redo all the work that you already spent all day doing once when lets say that the presentation is first thing in the morning.

Here is a way to make sure that your computer doesn’t crash when the power suddenly goes out when you are working on an important project at work or at home. This UPS battery is something like a surge protector but it has a series of batteries in side so that you do not loose all power at once.

With the UPS battery you will have a chance to save all your work and safely shut down the computer before you loose everything. Just think of the pain and embarrassment that you would not half to go through when you don’t half to redo all your work a second time around.

Plus just think, then you would not be too warn out and tired from trying to redo all the work that night for the next day if you waited until the last minute to get your work done.

Do you think that everyone would be better off if they would get a UPS Battery for their home and office? Lets see it would be a benefit because then you would not half to loose any of your hard work because of a power failure from the weather or from an accident.

Getting Rid Of Spyware

June 20th, 2008

To get rid of spyware, you have know what spyware is. Spyware is software installed on your computer that tracks what you do, whenever you are online surfing the internet. It then sends information back to the source and shows you banner ads that are based on what sites you surf. Most spyware is bundled in free software that you download from the internet. You can tell if the software you have has spyware, because you will see a banner in your web browser that is not normally there, or you will get pop ups offering you products or services whenever you surf.

Spyware can take up your memory and then make you computer run slower, and finally, will make your computer freeze. So to get rid of spyware you have to find it on your computer. A program that can help with this problem is Adaware. Make a search for this program on Google.com and you should find a site to download it.

Run this program and notice what it finds. Then restart the computer and run the program again and see if it finds any more spyware. If it does, run a search online on Google for Spybot Search and Destroy. Follow the same steps and see if you still have spyware. If you do, reboot your computer in safe mode then run both the programs again. This time the computer will search all files and should find other spyware that could not be found earlier.

Once the programs finish running, restart your computer, run them again, then go online and check for updates for the programs. If updates are available, download them and rerun the programs to identify and remove any newer spyware.

If you want to get rid of spyware and keep it from getting back on your computer, you should buy a spyware software CD from the computer store. Having this will allow you to subscribe to the service which will provide updates. If the software suspects that spyware is on the computer, it will alert you and will remove the intruder.

You should use one of these methods to identify and remove spyware because it will cause your computer to not run correctly. If you do not want to use any of these programs and do not download files from the internet, then you should tell anyone else that uses your computer not to do so either.

High Performance Notebooks Buying Info

May 5th, 2008

If you need a laptop which one should you get? There is a large range of mass market laptops that are extremely cheap and then you have those gaming laptops that are pricey and performance focused. Well it depends on your needs but you should always buy the best specification you can afford. You never know when you may get addicted to the latest game, only to realise your cheap laptop can’t handle it. Laptops meant for playing games are just high specification notebook computers which can easily run todays software and games which seems a smart investment if this is a long term purchase.

Intel has been dominating the notebook computer industry as long as I can remember. The centrino certification has signified a certain standard of performance however there has been a lot of confusion regarding what centrino notebooks are. Common misconceptions include thinking that just because the laptop has an intel processor that makes it a centrino laptop. A Few consumers still don’t understand that centrino is a marketing platform that implies the laptop has an intel chipset, intel processor and intel wireless card.

When buying a gaming laptop the processor, memory and video chip are the most important parts one should think about. You need a processor with a minimum speed of 2GHz and it should be dual core. 2GB is the min amount of ram need for playing games. To play games you need to have a dedicated viedo card. 256MB is the minimum dedicated graphics memory to look for. I think an Nvidia 8600M card should be good for playing all the new games well. For hardcore gamers get only the top of the range video cards.

So gaming laptops do offer the functionality of a desktop pc and if you want to play games then they play all PC games rather well too but what about gaming consoles? The PS3 and Xbox 360 could be a threat to the thought of a gaming laptop. Choosing just one is still difficult as gaming laptops still command a higher price for the added features and benefits they offer but the majority of consumers would be willing to pay the price to get the best of both.

Cost Of DNA Testing

May 2nd, 2008

DNA testing is the most reliable method of testing the true identity of a person, especially for establishing the accurate parental identity of a child. As most DNA tests are legally binding, such tests can be used in trials as evidence to convict murderers or establish the paternity of a child. Costs for DNA testing generally vary from lab to lab depending upon the size and condition of the sample to be tested, as well as on the usage of the test. For instance, a DNA test for paternity analysis costs somewhere in the region of $200; however, if the test is required for a paternity suit the cost might go up to $500 or $600.

DNA testing costs can range from reasonable to exorbitant, with easy-to-detect genetic linkage tests costing a few hundred dollars, while difficult tests like analysis for focal mutations cost thousands of dollars. Most DNA tests include prices for the entire process, from sample collection to analysis, written reports and even courier costs. However, when opting for a genetic test, it is advisable to find out any hidden cost attached to an analysis.

The cost of DNA testing also depends on the kind of analysis to be undertaken. For instance, in case of a standard DNA paternity test, a person might have to send only about $200, while a legal paternal DNA paternity test might cost around $600. Every additional request or specialized tests adds up to the total cost for genetic evaluation; for example, a standard paternal DNA test’s cost might go up by a few hundred dollars if the sample of an alleged relative is also added for analysis.

Although DNA testing costs are generally not covered by insurers, most insurance companies do cover the less expensive tests, and one can find the more information from their insurance agents before submitting a sample.

The Wages of Science

April 29th, 2008

In the United States, Congress approved, In February 2003, increases in the 2003 budgets of both the National Institutes of Health and National Science Foundation. America is not alone in - vainly - trying to compensate for imploding capital markets and risk-averse financiers.

In 1999, chancellor Gordon Brown inaugurated a $1.6 billion program of “upgrading British science” and commercializing its products. This was on top of $1 billion invested between 1998-2002. The budgets of the Medical Research Council and the Biotechnology and Biological Sciences Research Council were quadrupled overnight.

The University Challenge Fund was set to provide $100 million in seed money to cover costs related to the hiring of managerial skills, securing intellectual property, constructing a prototype or preparing a business plan. Another $30 million went to start-up funding of high-tech, high-risk companies in the UK.

According to the United Nations Development Programme (UNDP), the top 29 industrialized nations invest in R&D more than $600 billion a year. The bulk of this capital is provided by the private sector. In the United Kingdom, for instance, government funds are dwarfed by private financing, according to the British Venture Capital Association. More than $80 billion have been ploughed into 23,000 companies since 1983, about half of them in the hi-tech sector. Three million people are employed in these firms. Investments surged by 36 percent in 2001 to $18 billion.

But this British exuberance is a global exception.

Even the - white hot - life sciences field suffered an 11 percent drop in venture capital investments in 2002, reports the MoneyTree Survey. According to the Ernst & Young 2002 Alberta Technology Report released in March 2003, the Canadian hi-tech sector is languishing with less than $3 billion invested in 2002 in seed capital - this despite generous matching funds and tax credits proffered by many of the provinces as well as the federal government.

In Israel, venture capital plunged to $600 million in 2002 - one fifth its level in 2000. Aware of this cataclysmic reversal in investor sentiment, the Israeli government set up 24 hi-tech incubators. But these are able merely to partly cater to the pecuniary needs of less than 20 percent of the projects submitted.

As governments pick up the monumental slack created by the withdrawal of private funding, they attempt to rationalize and economize.

The New Jersey Commission of Health Science Education and Training recently proposed to merge the state’s three public research universities. Soaring federal and state budget deficits are likely to exert added pressure on the already strained relationship between academe and state - especially with regards to research priorities and the allocation of ever-scarcer resources.

This friction is inevitable because the interaction between technology and science is complex and ill-understood. Some technological advances spawn new scientific fields - the steel industry gave birth to metallurgy, computers to computer science and the transistor to solid state physics. The discoveries of science also lead, though usually circuitously, to technological breakthroughs - consider the examples of semiconductors and biotechnology.

Thus, it is safe to generalize and say that the technology sector is only the more visible and alluring tip of the drabber iceberg of research and development. The military, universities, institutes and industry all over the world plough hundreds of billions annually into both basic and applied studies. But governments are the most important sponsors of pure scientific pursuits by a long shot.

Science is widely perceived as a public good - its benefits are shared. Rational individuals would do well to sit back and copy the outcomes of research - rather than produce widely replicated discoveries themselves. The government has to step in to provide them with incentives to innovate.

Thus, in the minds of most laymen and many economists, science is associated exclusively with publicly-funded universities and the defense establishment. Inventions such as the jet aircraft and the Internet are often touted as examples of the civilian benefits of publicly funded military research. The pharmaceutical, biomedical, information technology and space industries, for instance - though largely private - rely heavily on the fruits of nonrivalrous (i.e. public domain) science sponsored by the state.

The majority of 501 corporations surveyed by the Department of Finance and Revenue Canada in 1995-6 reported that government funding improved their internal cash flow - an important consideration in the decision to undertake research and development. Most beneficiaries claimed the tax incentives for seven years and recorded employment growth.

In the absence of efficient capital markets and adventuresome capitalists, some developing countries have taken this propensity to extremes. In the Philippines, close to 100 percent of all R&D is government-financed. The meltdown of foreign direct investment flows - they declined by nearly three fifths since 2000 - only rendered state involvement more indispensable.

But this is not a universal trend. South Korea, for instance, effected a successful transition to private venture capital which now - even after the Asian turmoil of 1997 and the global downturn of 2001 - amounts to four fifths of all spending on R&D.

Thus, supporting ubiquitous government entanglement in science is overdoing it. Most applied R&D is still conducted by privately owned industrial outfits. Even “pure” science - unadulterated by greed and commerce - is sometimes bankrolled by private endowments and foundations.

Moreover, the conduits of government involvement in research, the universities, are only weakly correlated with growing prosperity. As Alison Wolf, professor of education at the University of London elucidates in her seminal tome “Does Education Matter? Myths about Education and Economic Growth”, published in 2002, extra years of schooling and wider access to university do not necessarily translate to enhanced growth (though technological innovation clearly does).

Terence Kealey, a clinical biochemist, vice-chancellor of the University of Buckingham in England and author of “The Economic Laws of Scientific Research”, is one of a growing band of scholars who dispute the intuitive linkage between state-propped science and economic progress. In an interview published in March 2003 by Scientific American, he recounted how he discovered that:

“Of all the lead industrial countries, Japan - the country investing least in science - was growing fastest. Japanese science grew spectacularly under laissez-faire. Its science was actually purer than that of the U.K. or the U.S. The countries with the next least investment were France and Germany, and were growing next fastest. And the countries with the maximum investment were the U.S., Canada and U.K., all of which were doing very badly at the time.”

The Economist concurs: “it is hard for governments to pick winners in technology.” Innovation and science sprout in - or migrate to - locations with tough laws regarding intellectual property rights, a functioning financial system, a culture of “thinking outside the box” and a tradition of excellence.

Government can only remove obstacles - especially red tape and trade tariffs - and nudge things in the right direction by investing in infrastructure and institutions. Tax incentives are essential initially. But if the authorities meddle, they are bound to ruin science and be rued by scientists.

Still, all forms of science funding - both public and private - are lacking.

State largesse is ideologically constrained, oft-misallocated, inefficient and erratic (the recent examples being stem-cell and cloning research in the USA). In the United States, mega projects, such as the Superconducting Super Collider, with billions already sunk in, have been abruptly discontinued as were numerous other defense-related schemes. Additionally, some knowledge gleaned in government-funded research is barred from the public domain.

But industrial money can be worse. It comes with strings attached. The commercially detrimental results of drug studies have been suppressed by corporate donors on more than one occasion, for instance. Commercial entities are unlikely to support basic research as a public good, ultimately made available to their competitors as a “spillover benefit”. This understandable reluctance stifles innovation.

There is no lack of suggestions on how to square this circle.

Quoted in the Philadelphia Business Journal, Donald Drakeman, CEO of the Princeton biotech company Medarex, proposed In February 2003 to encourage pharmaceutical companies to shed technologies they have chosen to shelve: “Just like you see little companies coming out of the research being conducted at Harvard and MIT in Massachusetts and Stanford and Berkley in California, we could do it out of Johnson & Johnson and Merck.”

This would be the corporate equivalent of the Bayh-Dole Act of 1980. The statute made both academic institutions and researchers the owners of inventions or discoveries financed by government agencies. This unleashed a wave of unprecedented self-financing entrepreneurship.

In the two decades that followed, the number of patents registered to universities increased tenfold and they spun off more than 2200 firms to commercialize the fruits of research. In the process, they generated $40 billion in gross national product and created 260,000 jobs.

None of this was government financed - though, according to The Economist’s Technology Quarterly, $1 in research usually requires up to $10,000 in capital to get to market. This suggests a clear and mutually profitable division of labor - governments should picks up the tab for basic research, private capital should do the rest, stimulated by the transfer of intellectual property from state to entrepreneurs.

But this raises a host of contentious issues.

Such a scheme may condition industry to depend on the state for advances in pure science, as a kind of hidden subsidy. Research priorities are bound to be politicized and lead to massive misallocation of scarce economic resources through pork barrel politics and the imposition of “national goals”. NASA, with its “let’s put a man on the moon (before the Soviets do)” and the inane International Space Station is a sad manifestation of such dangers.

Science is the only public good that is produced by individuals rather than collectives. This inner conflict is difficult to resolve. On the one hand, why should the public purse enrich entrepreneurs? On the other hand, profit-driven investors seek temporary monopolies in the form of intellectual property rights. Why would they share this cornucopia with others, as pure scientists are compelled to do?

The partnership between basic research and applied science has always been an uneasy one. It has grown more so as monetary returns on scientific insight have soared and as capital available for commercialization multiplied. The future of science itself is at stake.

Were governments to exit the field, basic research would likely crumble. Were they to micromanage it - applied science and entrepreneurship would suffer. It is a fine balancing act and, judging by the state of both universities and startups, a precarious one as well.

Passing Cisco’s CCNA and CCNP Exams: The ‘VLAN.DAT’ File

April 5th, 2008

CCNA and CCNP candidates who have their own Cisco home labs often email me about an odd situation that occurs when they erase a switch’s configuration. Their startup configuration is gone, as they expect, but the VLAN and VTP information is still there!

Sounds strange, doesn’t it? Let’s look at an example. On SW1, we run show vlan brief and in this abbreviated output see that there are three additional vlans in use:

SW1#show vlan br

10 VLAN0010 active

20 VLAN0020 active

30 VLAN0030 active

We want to totally erase the router’s startup configuration, so we use the write erase command, confirm it, and reload without saving the running config:

SW1#write erase

Erasing the nvram filesystem will remove all configuration files! Continue? [confirm]

[OK]

Erase of nvram: complete

SW1#rel

00:06:00: %SYS-7-NV_BLOCK_INIT: Initalized the geometry of nvram

SW1#reload

System configuration has been modified. Save? [yes/no]: n

Proceed with reload? [confirm]

The router reloads, and after exiting setup mode, we run show vlan brief again. And even though the startup configuration was erased, the vlans are still there!

Switch#show vlan br

10 VLAN0010 active

20 VLAN0020 active

30 VLAN0030 active

The reason is that this vlan and VTP information is actually kept in the VLAN.DAT file in Flash memory, and the contents of Flash are kept on a reload. The file has to be deleted manually.

There’s a little trick to deleting this file. The switch will prompt you twice to ask if you really want to get rid of this file. Don’t type “y” or “yes”; just accept the defaults by hitting the return key. If you type “y”, the router attempts to delete a file named “y”, as shown here:

Switch#delete vlan.dat

Delete filename [vlan.dat]? y

Delete flash:y? [confirm]

%Error deleting flash:y (No such file or directory)

Switch#delete vlan.dat

Delete filename [vlan.dat]?

Delete flash:vlan.dat? [confirm]

Switch#

The best way to prepare for CCNA and CCNP exam success is by working on real Cisco equipment, and by performing lab tasks over and over. Repetition is the mother of skill, and by truly erasing your VLAN and VTP information by deleting the vlan.dat file from Flash, you’ll be building your Cisco skills to the point where your CCNA and CCNP exam success is a certainty.
