The History of Search Engine



The launch of Wolfram Alpha this month has some wondering if we’re moving into a new age of search. We certainly could be, but it’s unlikely it’ll be a Google-free world.

Indeed, this latest development – as cool as it is – is a continuation of a long string of innovation the sector has seen since the birth of the web. Wolfram Alpha is likely to fill one niche area of the market, while other innovations step-up to solve other problems. That may still leave Google holding the bulk of the market, but at the very least it’s encouraging that so many are continuing to develop new ideas despite such a near monopoly.

How search works

Every search engine is a bit different, much to the annoyance of search engine optimisers the world over. That said, search engines basically send out a robot or spider across the web to follow each and every link. The service then indexes what it finds, with different engines storing different bits – for example, Google, stores everything found in the source of the page, while others just look at what’s displayed.

When a user searches all these indexed pages, relevancy comes into play. Google’s PageRank is the most famous algorithm, but every engine has its own way of finding the best results.

But it’s not just the web that’s searched. Wolfram Alpha is promising to return answers, not just documents, from across the web, while many other searches look at more than the web or even limit themselves to specific niche areas of it. Consider the Pirate Bay. The now-notorious site offers a search of BitTorrents, specific file types that are key to its users. Or consider Google Maps – it is searching for anything that can be geographically pin-pointed. Even services like Twitter are changing the way search works, by letting us search what people are tweeting about.

Before the web

Quite simply, the world didn’t need search in the early days. In the beginning, all web servers were listed on a CERN website that was edited by a man then known as Tim Berners-Lee – those were the days before he was knighted.

Once that list became unwieldy, a search tool dubbed Archie – that’s ‘Archive’ without the ‘v’ – searched via a database of web servers. Soon after, Gopher’s rise led to a pair of new search tools, comically dubbed Veronica and Jughead, which searched using file names and menu titles.

It wasn’t until 1993 that the first robot came about. It was called the World Wide Web Wanderer, but it was for measuring the web, not searching it.

Modern search kicked off in December of that year with JumpStation, which used a robot to crawl the web, indexing it to make it searchable – the three key aspects of modern, or at least current, search. JumpStation was limited to titles, but another system called WebCrawler took it a step further the next year, managing to search full text.

Going commercial

Lycos kicked off the money making in 1994. The Carnegie Mellon project not only robotically indexed every word on a page for searching, but it was also used by the public and went commercial.

But it had competition. Among the pack that emerged over the next few years was Excite, Magellan and Infoseek, in addition to Altavista and Yahoo. Perhaps surprisingly now, at the time Yahoo didn’t search via full pages and keywords, but instead used a web directory system.

By 1996, dominant browser Netscape was struggling to keep things fair, so for a fee of $5 million it let search engines buy the search spot on the Netscape page in rotation.

But the search engine market was set for a shakeup. In that same year, Larry Page and Sergey Brin teamed up at Standford University to develop a search engine based on relevancy, initially dubbing it BackRub. Two years later, Google was incorporated as a company with investment of $1 million; a year later, they had $25 million to play with.

Google time



In 2000, the market as we know it now started to take shape. The dot com bust took down some, but Google’s PageRank bumped it into the limelight, and it started offering advertising that year.

Still, competition remained. In 2002, Yahoo upped its game by picking up proper search tech in the form of Linktomi in and later Overture, which owned Altavista. Yahoo even used Google’s search until 2004, when it melded its acquisitions together into a coherent search tool. That year also saw Microsoft enter the ring, creating its own tool in 2004.

But Google’s IPO in 2004 showed who was really in control of the market, putting the net worth of the company at about $23 billion. Now, it gains several hundred million queries a day. That said, Google has been hit by privacy and other controversies, and notably misses searching the “deep web” – all the data that isn’t linked the way Google likes it.

Challenging Google’s dominance

While Google has seen a few challenges to its market dominance, although none have yet to make much of a dent.

Last year, an engine named Cuil launched, to much media coverage. While the company itself didn’t use the phrase “Google Killer,” a lot of journalists and bloggers did. And it sure didn’t look good for Cuil – or any other Google challengers – when the service was derided for poor results and performance.

Last year, Cuil co-founder Tom Costello told IT PRO: “Other people tend to want to actually make it a story about ‘oh, here’s David coming along against Goliath.’ And again, I think that with the story of David and Goliath, David doesn’t always win on the first shot. A lot of time, people want a very quick resolution to these things.”

Even though Cuil continued to struggle to gain market share in the following months, Costello thinks the service has a future. “Even when you see Google – built to the kind of dominant position they have - it took them 10 years to build to that position. Search is not a business where you have overnight success. It’s not a business where you change the behaviour of billions of people worldwide who use search overnight.”

Maybe the challenge won’t come from a new service, but from established players instead. That’s certainly the goal Microsoft had in mind when it made a massive bid for Yahoo last year. While the bid failed, Microsoft has continued to try to partner with Yahoo on search.

At the moment, Microsoft’s third and fourth ranked Live and MSN searches pull in about five per cent of the market, with second-ranked Yahoo adding another 10 per cent, according to Net Applications. Google takes about 81 per cent, though, meaning it has a lot of room for error to stave off any challenges, even from big players.

While a straight-up deal between Yahoo and Microsoft could cause some disruption in the online ad market, it’s going to take something new to topple Google from its throne. Could pairing a big name with a new idea be enough? If Wikia Search is anything to go by, then the answer is no.

That project was backed by Wikipedia founder Jimmy Wales, so it had an attention-pulling big name from the start. It was never intended to overtake Google – Wales said he hoped one day to get five per cent of the market – but to offer an open, transparent search alternative. Wales said at the time: “The idea that Google has some edge because they've got super-duper rocket scientists may be a little antiquated now.”

Instead, Wikia Search looked to crowdsource its relevancy, asking users to rank the results of a search, rather than rely on mysterious algorithms like Google. But the service never took off, and as the recession hit, Wales shut it down, noting it was pulling just 10,000 unique users a month.

What’s next?

While Wales has promised to return to search as soon as finances allow, others are looking for new ways to find information on the web. Sir Tim Berners Lee is still at it, pointing to the semantic web – and in turn search – as the future. This looks to remove ambiguous words from the search process, making results more specific.

Microsoft is also set to be launching its new search tool as early as June. Codenamed “Kumo” at the moment, it looks to be a rebrand of its current Live search, but includes a few changes such as using categories to separate out different types of results.

And then there’s Wolfram Alpha, the engine that promises to return answers, not documents. While it certainly looks impressive, it’s so unlike what people currently use search for that it’s unlikely to be the force that topples Google.

But then, in such a fast moving area of the tech world, who knows when the next Google could be created in a university somewhere around the world…

Need to Know : Firefox 3.5

Version 3.5 of the Firefox web browser is imminent. We explain what to expect from this major update.

By Benny Har-Even

Firefox 3.5

While we agree that Internet Explorer has come on a long way, we still don’t think it’s the best option out there.

There are now several web browsers out there, all competing for your attention and the biggest of these alternatives, Firefox, has just received a major update.

What is Firefox?



If you recall your web history, in the late nineties, the ‘browser wars’ were conducted between Microsoft and Netscape. We all know who won that one, but out of the ashes of Netscape came an open source browser project – originally Phoenix (out-of-the-ashes, geddit), then changed to Firebird, and then eventually to Firefox.

Since version 2, released in October 2006, it’s started to significantly eat away at Microsoft’s market share and version 3 achieved a over eight million downloads in a single day - getting itself into the Guinness World Records in the process.

Firefox is widely liked for its expandability, with its design allowing for the creation for third-party plug-ins or ‘add-ons’. These provide extra features and make for a highly customisable web browsing experience.

What happened to Firefox 3.1?

Soon after version 3.0 was released, Mozilla began to take up the version 3.1 update and this was supposed to have been released some months ago. However, as new features and enhancements were added it was renamed to version 3.5, to better reflect the number of improvements.

OK, so what’s new in 3.5?

There are a number of new features in 3.5, but the one that many will care about it promised speed improvements – competition has hotted up in recent months with both Google’s Chrome and Apple’s Safari 4 claiming speed records, and Firefox 3 is starting to feel its age.

It’s all to do with the use of the Javascript rendering engine. Javascript is used for much of the new fangled Web 2.0 world we live in today, so getting it speedy is important - and Mozilla claims that it’s twice as fast as Firefox 3 was and can compete with Chrome and Safari.

The new version also supports HTML5, the latest web standard and this contains support for a new video tag – which means that you’ll be able to watch video in your browser without any need for a plug-in. The videos are in the open source Ogg Theora format though, and Daily Motion is the only major video site to support it as yet.

Other new bits include an ‘In-Private’ mode – just hit ‘Ctrl-shift-P’ to stop Firefox from remembering your browsing session – perfect for searching for that new job or - ‘ahem’ – other activities. You can also tell 3.5 to forget a site you’ve been to after the fact, just by finding and deleting in the history.

Tear it Up

We also like being able to tear off your tab and drag it out to make a new windows (nicked from Chrome) and ‘Location Aware Browsing’, so if you’re searching for information you don’t need to tell it anything – it knows where you are. Yes, you can turn it off, you paranoid people.

Downloadable fonts can help make web site start to look ‘the way the director intended’. This means you don’t need to have a font already on your system for the web page to use it, negating the need for designers to user static images, which makes for a more editable and searchable internet.

Finally, the ‘session restore’ has been improved, so in the event of a unexpected shut-down or crash, everything is remembered, which could be great if you’re composing an email in the browser.

Sounds awesome! When can I get it?

Now. Firefox 3.5 is available for download.

Look out for our full review of the full version on the site later this week.

Opera 10 beta review

By Darian-Graham Smith, 12 Jun 2009



Opera was a real innovator in the browser space, but its desktop offering is something of the forgotten man in the industry. We take a look at the beta of its latest release.

Tabbed browsing, plug-ins, rendering speed. Others such as Firefox and Safari may now crow loud about these but Opera had them first. Indeed for years it was the definitive browser for the clued-in geek, and now is forced to jostle for attention alongside fast, flashy upstarts such as Chrome. Can the new public beta of Opera 10 see off the newcomers?

The fightback starts with a redesigned front-end: the drab toolbar of Opera 9 has been replaced by a bolder design, with clearly delineated buttons bearing revamped icons. It does look more inviting, but functionally it's near-identical and, truth be told, it now looks a little like Safari.

Thankfully, Opera keeps its tabs within the main window, which we think is more usable than the non-standard way Safari carves up the title bar. You can also now drag the search field to resize it, although this feels like cosmetic tinkering rather than a functional improvement.

In fact, the big new interface feature is wholly invisible when you start Opera 10. To find it, you need to drag the toolbar downwards; that's not an intuitive operation, but when you try it you'll be delighted to see your web page tabs grow into thumbnails of the pages themselves.

Sadly, no matter where you've scrolled to, the previews show only the top of the page you're viewing - or sometimes, a section further down the page if something about the layout confuses them. Either way, they all too often don't resemble the pages they represent.

As a final interface enhancement, you can also now customise the Speed Dial grid. Where Opera 9 always showed a grid of nine page previews, the new beta will accommodate anything from four to 25 pages. The latest beta of Safari has a similar option, so it's good to see Opera catch up so quickly.

Computer Accessories




A home away from home is a great thing, so why not have an office away from the office too?The spare room or a quiet corner can be a perfect place for productivity. To outfit your workspace, you might need to invest in some new hardware like a second computer, a bigger monitor or a high-quality printer. Once you've got your home computer set-up, you'll need to connect it to the Internet or network it to other computers and peripherals in the house. With a good grasp of the facts and a firm idea of your work habits, you'll be ready to make sensible choices for your home-made office.

  • The Computer. Not everyone needs the same level of performance in a home office computer. You might use your computer primarily for word processing and email which requires little processing power. On the other hand, you may want more power to run database analysis, large spreadsheets or graphics applications. The type of work you do and your work load will determine whether you need a computer with a lot of brawn or just a little.
  • Processor. A computer's processor or central processing Unit (CPU) is the engine that powers the device. The speed of the processor is called the clock speed which measures how fast the processor can carry out instructions. Speed is measured in MegaHertz (MHz) and is one measure of a computer's power. A typical home office Windows PC should have at minimum a 500 MHz processor. A power user would probably prefer 800 MHz or higher. If you know your computing needs are modest, and you want to save some money, an older machine with a slower processor is worth considering. When looking at an Apple Macintosh, keep in mind that you can't simply compare processor speeds with Windows machines, as the two types of computers have different system designs. Macs generally have lower processor speeds in MHz but don't let that fool you. Newer Macs like the iMac can definitely keep pace with PCs.
  • Random Access Memory (RAM). When the computer is turned on, RAM is used to hold the operating system, applications and data that you're currently running. Information in RAM is rapidly available to the processor. When RAM fills up, the computer slows down because it now has to retrieve information from the slower hard drive. Imagine documents on your desk in front of you, readily at hand when you need them. But when your desktop is full, you have to file and retrieve documents elsewhere, which takes more time. The amount of RAM you need is influenced by the type of applications you use. Graphics programs like Adobe PhotoShop or Illustrator use a fair bit of memory. Word processing and spreadsheet programs use somewhat less memory. Users who like to multi-task and prefer having multiple applications running simultaneously will definitely want plenty of memory. More memory gives you a larger "workspace" and makes your computer perform faster with fewer glitches. A typical user needs at least 64 MB of RAM with 128 MB becoming the norm. In virtually all computers, you can expand the memory as you need more.
  • Hard Drive. This is the computer's filing cabinet where all your applications and data are permanently stored. Most users can fit many years of productivity into a 6 to 10 GB hard drive. If you need to store a lot of information like several years of business records or image catalogues, then you may want a more spacious hard drive. Luckily, a bigger hard drive won't cost you that much extra. Alternately, you could invest in a removable storage drive.
  • Expansion. It never hurts to get a system with room to grow, especially if you foresee your home office needs evolving. Find out how many RAM slots a system has and what the maximum amount of RAM is. Adding expansion cards to your system for 3D graphics or ethernet will increase the functionality of your computer. Look for a system with two or three free expansion slots and room for additional disk drives.

To Have or Not to Have Supply Chain Software: Can the Riddle Be Solved?

by Khudsiya Quadri



The first question that comes to mind is: will supply chain software help reduce the cost of the supply chain? So the riddle is to have or not to have supply chain software within your organization…?

For an organization to be efficient and profitable—i.e., successful—a well-managed supply chain is critical. In today’s market, customers’ needs are changing so rapidly that organizations must be quick to respond to these rapid changes while making sure the cost of materials and finished goods stays low. Supply chain management (SCM) software helps organizations achieve this low pricing for their customers by providing better visibility into changes in customers’ demands, enabling negotiation of best possible prices from suppliers, helping optimize inventory levels at various stages of processes, consolidating distribution networks, and optimizing freight and logistics.

by Khudsiya Quadri

So do all of these concerns mean SCM solution market has not see a change in demand for SCM solutions, even though the entire worldwide economy is in a downturn? It’s true the enterprise software market has slowed down, but the market for SCM solutions is still in rapid growth state. According to AMR Research group, the worldwide market for SCM software is expected to reach or exceed $8 billion by 2010.

Now the question: what does supply chain software encompass that makes it so crucial for all types of organizations? Firstly, we need to understand what SCM is. Basically, it’s a combination of science and software that brings together all the steps within a supply chain—sourcing, procurement, inventory management, advance planning and scheduling, and warehousing and distribution. With the help of SCM software, organizations are able to organize and automate the forecasting, planning, execution, and control of these significant processes.

As well, flexibility within SCM software is essential to being able to integrate with third parties who are involved in an organization’s supply chain, toward providing end-to-end visibility. SCM software is developed to provide organizations with advance capabilities for data communication, collaboration, and coordination with vendors and suppliers, as well as transportation and shipping organizations. The chain does not end here; other partners of suppliers and vendors as well need to be incorporated within the whole supply chain software network.

Another question arises: what are the cost benefits for your organization to implement SCM software? Here are some important factors:

  • Firstly, SCM software helps an organization manage its entire supply chain network by providing visibility to all the activities happening across all suppliers, manufacturing plants, and distribution centers.
  • By centralizing data and information, SCM software assist organizations make effective decisions about production, distribution, and logistics strategies of goods. This in turn means SCM solutions can help companies eliminate inaccuracy in production and logistics. As well, SCM solution can bring efficiency to processes and remove delays that result from a lack of coordination between departments and third-party organizations.
  • By sharing information upstream and downstream, SCM solutions can give all parties involved a better picture of what’s happening so no gaps will be found in the processes. Because of SCM’s ability to enable collaboration along the entire supply chain, all key information regarding changes to a customer order or demand will be communicated more effectively, giving all parties involved a better plan of action for inventory management, logistics planning, and cash flow management.
  • As supply chain software makes information clearly available, it allows effective communication with other partners, which in the end helps organizations improve logistics and tracking of goods, and enables them to remove or fix any problems before they become uncontrollable.
  • SCM solutions can help organizations achieve their inventory levels and delivery dates through its variety of modules.

Now the time has come to answer the riddle about whether you should have SCM software within your organization or not. For many organizations, the supply chain network is becoming more multifaceted; for this reason, many organizations are facing multiple challenges in managing their enormous networks. Any company with a complex network of suppliers, vendors, and other partners can see rapid benefits from a SCM software implementation. SCM software helps the organization make its operations run more smoothly throughout its supply chain, from timely execution to delivery of product.

Supply chain software solutions are not just for manufacturers or production plants; in today’s marketplace, everyone is beginning to benefit from using supply chain software. For example, retailers and service providers are a couple of examples of the types of organizations that are using SCM software to boost efficiency and gain visibility throughout their networks. Higher visibility of what’s happening during each process within a supply chain has helped organizations achieve considerable return on investment (ROI).

Once SCM software is in place at an organization, it gives that organization the ability to produce and deliver only the amount of product needed, when it’s needed—without any delay. As noted in my previous blog about better inventory management, an organization’s main objective from its supply chain is to have the right inventory, at the right time, at the right location, and in the right quantity. Basically, it is more than just visibility into the supply network; it’s collaboration within the network as well.

Nobody says it’s easy to integrate SCM software within an organization’s enterprise structure. SCM software could be added on to an organization’s current enterprise resource planning (ERP) application, or it could just replace some manual process done on spreadsheets or in a Microsoft Access Database. To maximize cost savings, it is key to have a SCM software that is capable of integrating with other systems—ERP, customer relationship management (CRM), accounting, or financial modules—for better information flow and ROI. As well, many parties both internal and external play equally key roles in SCM’s success. We have a perfect example of this in the relationship between Wal-Mart and Procter and Gamble (P&G). By implementing SCM software, Wal-Mart gained by having the right amount of inventory on its shelves, while P&G knew exactly what was needed, when it was needed, and where it was needed.

Keep in mind that employees of organizations should never be threatened by use of an application or software. To have a successful supply chain application in place, it’s important to merge the expertise and knowledge of employees with the software. This will bring greater ROI and profitability in the long run. As well, a system is often only as good as its users and the data input into it.

Essentially, it’s important to ask questions before any kind of software implementation, to find out if you need a new SCM solution or not. Once that is out of the way, try to find the software that is most compatible with your business and that will integrate with your current applications and systems. Lastly, remember to have a dependable software provider by doing research on its size, global reach, and financials—but never overlook a review of its past customers and current customer feedback in order to get a complete picture of the software provider’s strengths and weaknesses, as well as the strengths and weaknesses of its software product.

Don't Buy Software Online Before You Read This 10 Tips To Buying Software Online


Buying software online can be tricky, especially if you are new to shopping via the internet. Whether you are upgrading an existing software package or looking for a specific program to install, the process will be a lot less complicated if you know what to look for.

Tip # 1
Read customer reviews. Many popular online stores, such as Amazon, allow users to leave their comments about a particular product. Reading other customer reviews may help to make your decision easier because it gives you an idea of others who have experienced the product firsthand.

Tip # 2
When considering any type of software, make sure that it is compatible with your computer. Most software requires a specific processor type, such as Pentium or Celeron, and a certain amount of free hard drive space. The reason is because, in order for software to function properly at quickly, the computer must be able to handle the application. By being familiar with your computer's configuration, you will be able to select the right software.

Tip # 3
Become familiar with the software by reading it's description and capabilities. Before purchasing any type of software, you should make sure that it is exactly what you want or will enjoy learning. Often times, after software is opened, there is no refund policy for buyer's remorse.

Tip # 4
Purchase software from a reputable company. This will ensure customer service, reliability, quality products and timely shipment. By purchasing software from a reliable source, you will also ensure that the title is authentic and not an illegal copy. The best way to check out a business's reputation is through the Better Business Bureau.

Tip # 5
The best part of shopping for software online is the competition. Because there are so many retailers, prices are more competitive than if only one store had the software that you want. Shop around and compare prices before making a final decision.

Tip # 6
When making a purchase online, consider using a credit card. Most credit card companies provide a dispute resolution process, which is beneficial if the product is not delivered, is not as advertised or is damaged and the company will not stand behind the transaction.

Tip # 7
If purchasing from another individual, such as often the case with online auctions, confirm that the software has all manuals and/or product keys to ensure proper installation.

Tip # 8
Learn about the company's return, refund and/or exchange policy. In many cases, especially with software, the company may refuse to accept the product back for a refund. However, there is always the possibility that a program is damaged or doesn't function properly, in which case the store should honor the purchase with an exchange for the same title. When buying software online, it's best to purchase from a store that is reasonable when it comes to exchanges if not refunds.

Tip # 9
When purchasing software online, take a moment to look at the company's shipping costs, methods and availability of a way to track the package following shipment.

Tip # 10
Common payment methods include credit cards, checks and/or money orders. If you want to purchase software online, you will need to do so from a company that accepts a convenient payment method. If you do not have a credit card, most companies will accept a mailed payment. Most companies, however, recommend not sending cash.

4 Programs For Your Computer [Smart and Free Programs]


One of the fun parts of owning a computer is, of course, access to the internet. The worldwide web is chock full of useful information, readily available at your fingertips! It is also home to potentially lethal viruses, many of which can wreak havoc on your system within moments. The following four programs can help you avoid trouble; best of all they are absolutely free.

Firefox : a web browser for the ages. Okay, a web browser that beats Internet Explorer by preventing pop ups and harmful scripts from being downloaded to your computer. Lots of nifty features too, including tabbed browsing, live bookmarks, and tons of add-on features.

Spybot Search and Destroy : gets rid of adware, spyware, and malware. Blocks the installation of spyware before it occurs; works in conjunction with anti-virus software, not as a replacement for one.

AVG Antvirus : offers basic antivirus protection including scanning email attachments for viruses and scanning of all hard drives, removable drives, and external drives on your computer. A paid version does some additional tasks and includes technical support.

Zone Alarm : if you don't have a firewall installed on your computer, you are opening yourself up to potential catastrophic security breaches. With Stealth Mode enabled you can search the internet in private, away from the intruding eyes of those who might want to steal your important information.

As with many freeware programs, 'pro' or professional versions of the software are sometimes available to give computer users a maximum amount of protection, for a price. Still, all four of these programs have something to offer and are worth exploring. Your computer safety and privacy is essential, insure it today by downloading the programs that are right for you.
