The CRT Display Lives on, in Disguise In December 2006, Toshiba announced that it was on track to mass-produce SED TV sets by 2008. Production will be in cooperation with Canon, which has been working on the technology since 1986. Small-scale output will commence in 2007, but when the inevitable computer monitor derivatives will become available is not yet clear. Each Pixel of a SED (surface-conduction electron-emitter display) is an individual device which produces electrons to excite a surface phosphor coating, in a similar way to a CRT. Each device consists of a thin slit across which electrons tunnel when excited by moderate voltages (tens of volts). When the electrons cross electric poles across the thin slit, some are accelerated toward the display surface by a high voltage gradient between the display panel and the surface conduction electron emitter. The energy carried by the electrons is given up to the phosphor on impact to produce the pixel. The claimed advantages
for SEDs are: http://www.canon.com/technology/canon_tech/explanation/sed.html AT, Dec06 Singapore is the latest world-class city (actually, it is a nation with a population of 4.6m people) to commit itself to providing a wide coverage WiFi service for its citizens. The estimated set-up cost of the system is S$100m (£33.2m), with S$30m of this being provided by the Singapore government. The remaining S$70m will be supplied by three telecom operators, SingTel, iCell & Qmax. Internet access will be available in most public areas at speeds of up to 512kbps. This is rather slow broadband – but it will be free for at least two years from the start date of September 2007. The stated aims of the new development are to “broaden the opportunities for all segments of the population to access and benefit from technology”, together with the determination to “create digital opportunities for all Singaporeans and never allow a digital divide in our society.” Worthy goals that London should take heed of – self congratulation for the success of the People’s Network is now beginning to look a little self indulgent, as the UK digital divide reopens in the WiFi access area. To ensure that the poor of Singapore do actually benefit from the WiFi network, the government will offer 10,000 subsidised computers to low-income families with school age families.
Nortel has integrated active RFID tags with GPS receivers. The tags communicate with a tag reader which then uses the municipal WiFi network to report the position of the asset. Such a system does not have to be limited to tracking assets which are inherently mobile. A normally fixed, high value asset which suddenly becomes mobile is probably being stolen and its whereabouts is of great interest to the police.

Changing Cost of Broadband Services
*purchasing power parity is a method of adjusting currency exchange rates in order to equalise the purchasing power of the currencies. Coincidently, or
possibly not coincidently, BT has announced that it has recently installed
2,300 km optical fibre as part of its IP based network transformation. The Financial Effects of Implementing RFID Technology For some time, academic and public libraries in the developed world have been implementing rfid technology to manage their stocks (see RFID below). Last month, the public libraries of the city of Hamburg became the latest to start introducing it. The advantages of rfid systems are obvious but it has been rather difficult to obtain reliable, quantified information on how these advantages affect overall performance. The Dutch bookshop chain Boekhandels Groep Nederland (BGN) has now published the results of a trial that it has carried out in one of its shops BGN tagged the stock of its Almere outlet from April 06 and found that, in the following 6 months, its sales increased by 12%. This improvement is attributed to the ease with which customers were able to locate books. The store has also cut back its inventory time for each box of books, from four minutes to a few seconds. Misplaced books are also found faster. If these cost reductions were replicated in all 42 BGN stores, handling 7 million books per year, it is estimated that $3.8 million per year would be saved. The increased turnover and reduced costs have resulted in plans to introduce the technology in a further 16 BGN stores. AT, Nov 06 More information: http://www.rfidlowdown.com/libraries/index.html Microsoft Corp. released Internet Explorer 7 on 18th Oct. This is the first major upgrade to its Web browser since 2001 and is designed to counter the inroads that Mozilla’s Firfox product has been making in a market segment dominated by Microsoft (See Browser Wars & Mozilla Gaining Ground below). Firefox features such as an integrated search window (allowing users to carry out a Web query without opening another page), tab browsing (allowing toggling between different sites) and a pop-up window blocker have now been incorporated in IE7. Unsurprisingly, IE7 uses Microsoft’s Windows Live as the default search engine, whereas Firefox uses Google as the default. One of the advantages claimed for IE7 is the ability to restore work after a browser/PC crash. Microsoft now has a product which can compete very well with the current Firefox browser. However, Mozilla plans to release an upgraded browser, Firefox 2, within the next few weeks. A recent survey by
OneStat.com has found that Internet Explorer has a 86% global share
and Mozilla Firefox 11.5%. Within the very important U.S. browser market,
80.77% of users surf the Web on IE and 14.88% on Firefox. Firefox is
most popular in Germany (33.4%); Australia (25.5%); and Italy (21.6%). IE 7 is available
immediately to Windows XP users and it will eventually serve as the
default browser for Microsoft's much-heralded Windows Vista operating
system, due to be released to consumers in early 2007. AT, Oct 06 The European Commission has called on Member States to contribute to the European digital library by setting up large-scale digitisation facilities to accelerate the process of getting Europe's cultural heritage on line via the European Digital Library. At present, only a small fraction of the cultural collections in the Member States is digitised but, by 2008, it is planned that two million books, films, photographs, manuscripts, and other cultural works will be accessible through the Digital Library. It is expected that his figure will grow to at least six million by 2010 and will ultimately be much higher, as potentially every library, archive and museum in Europe will be able to link its digital content to the new library. Obviously, the input from the UK’s public library services will be limited. However, the academic libraries have an enormous amount of suitable material and a good start has been made in digitising this. It is to be hoped that the Google / MicroSoft initiatives in this area will be complementary rather than competitive (see: Open Content Alliance & Google Flexes Muscles ). The European Library portal is at: http://www.theeuropeanlibrary.org/portal/index.htm Further information: http://europa.eu/rapid/pressReleasesAction.do?reference=IP/06/1124&format=HTML&aged=0&language=EN&guiLanguage=fr AT Sep. 2006 The Bloomberg New York City administration is slowly becoming more receptive to the concept of providing WiFi access for the public. Unlike other large US cities (e.g. San Francisco, Pittsburgh and Sacramento) where free access is becoming the norm, NY City has been reluctant to do more than pontificate about the supremacy of private enterprise in the USA and it has been left to the students of Monroe College and local community groups to set up hot spots in the city. Now, the city no longer expects to make money from any WiFi ventures in its jurisdiction and, by the end of the summer, ten of its parks will have WiFi access provided (eight locations within Central Park). In addition, squares in Manhattan, the Bronx and Queens will be covered. A Senator representing New York State, Chuck Schumer, has stated that he will introduce a bill to provide US federal funds to communities wishing to install WiFi systems citywide or countywide. Reuters reports that the mayor of Paris is planning to install 400 WiFi access points in the city’s public areas such as parks and libraries. Some free access is expected when the system goes live next year. Pity poor London. More information: San Francisco Unwiring , http://www.nycwireless.net , http://today.reuters.com/news/home.aspx The semiconductor arm of Philips, the multinational electronics group, has announced the launch of its next generation of rfid (radio frequency identification) chips. The company, the world’s largest producer of rfid chips, is targeting the library market for its new product via collaborating hardware manufacturers and system integrators. Rfid technology has been around for some time but has only made a small impact on the library world (there are only a few hundred libraries using it, worldwide). Probably, the reason for this is the fairly high cost. However, costs are falling as the retail market increasingly adopts the technology. The retail market segment will need very many million items per year and economies of scale will result. The standardization of library system technology that is both ISO15693 and ISO 18000-3 compliant will also help in rfid take-up in libraries. North American libraries are leading the adoption of rfid technology, but the Netherlands has recently decided that its libraries would also utilise it. UK libraries seem to be taking a wait and see stance. For hard-pressed UK local authorities, a reduction in the cost of book issuing is potentially the most attractive aspect of rfid technology. A borrower does not have to struggle with a bar code reader to take out /return a book via a self-service terminal. So these terminals become much more user-friendly and can be deployed on a wider scale. Indeed, the 2 metre range of the new devices suggests that dedicated terminals may not be necessary anyway. Grouped library catalogue computers could possibly be used or even People’s Network computers. One of the most frustrating aspects of trying to use a public library as a reference source is the mismatch between the library catalogue and the actual stock on the libraries’ shelves. Although staff do periodically check that books which have not been issued for a given duration are actually on the shelves, this is only a partial remedy and it is quite time consuming (costly). With rfid, proper stock-taking can be quickly accomplished and, in theory, could be undertaken each day to ensure efficient stock management, at almost zero cost. The remote searching of on-line catalogues would thus become far more useful. More

As an alpha release, it is still in the development phase and is still some distance away from a final release. The current full release of Firefox (version 1.5) has been nibbling away at the market dominance of version 6 of MicroSoft’s Internet Explorer (see Mozilla Gaining Ground below) and MicroSoft has been working hard to bring out an upgrade to its offering to counter this (IE7 is now at betta 2 release). Both IE7 and Firefox 2 are believed to have final release dates at the end of the year. The more seamless operation with the Windows operating system that MicroSoft can offer with its browser product is a huge advantage, so Mozilla has to offer other advantages to offset this. MicroSoft’s position has been further strengthened in this respect by Apple computers now running the Windows system.

May 06 Progress Towards the $100 Dollar Laptop Nicholas Negroponte, a professor at the MIT, has been developing the concept of low cost computers for third world countries for some years and reported project progress at the recent LinuxWorld event. The Negoponte led one laptop per child (OLPC) initiative has obtained $29 million in funding for engineering. It is expected that the project launch will be in 2007 with shipments of between 5 million & 10 million units initially in China, India, Thailand, Egypt, Nigeria, Brazil and Argentina. The key to achieving the target $100 price for the laptop is the huge volumes needed – up to 100 million per year. Initially, the computer will cost $135, although it is expected that this will fall to hit the $100 target by 2008. The cost may even drop as low as $50 in 2010. Negroponte has pointed out that 50 percent of the cost of a normal notebook is attributed to sales, marketing and distribution costs. OLPC claims that it has no such costs. In addition, OLPC expects to avoid the 25 percent of total cost contributed by a Windows operating system license by using Linux instead. The remaining 25 percent of the total normal cost is that of the display. OLPC will reduce this by utilizing a dual-mode display that is both reflective and transmissive i.e. reducing the backlighting requirement. The $100 laptop computer will have a 500MHz AMD x86 processor and 128MB of DRAM & 512MB of Flash memory. It will have a power drain of less than 2 watts, which is expected to be generated by windup power, similar to the successful radio designed for the third world market. Wi-Fi connectivity will be provided and there will be three or four USB ports. Although the $100 laptop does not appear to be very attractive for the more developed markets such as the UK, the enormous component volumes that will be required for its manufacture will have a great influence on the design of computers intended for those markets and will, inevitably, result in further price erosion there.

April 06 There has been much high volume comment from, and inspired by, large US telecomms. companies about the supposed unsustainability of the business model used by schemes offering free wireless broadband internet access to city communities. Whilst these incumbent service providers heavily criticize the pioneering municipal WiFi/WiMax schemes, they are quietly beginning to follow the same strategy themselves. Sprint is now setting up two free wireless internet access zones in a suburb of Las Vegas to test the idea before rolling it out. Verizon and Time Warner are also companies that have had an unpublicised change of heart. Of course, this about turn has nothing to do with the fact that large, non-telecoms companies (such as IBM & Google) are showing intense interest in the sector, or has it? Further
information: http://roisforyou.blogspot.com/2006_03_01_roisforyou_archive.html AT, Mar 06 Six bids for the San Francisco citywide WiFi system were received by the city on 21st February. As predicted, Google was one of the bidders (see Google Flexes Muscles ). The search engine company has teamed up with EarthLink, the well-known ISP, to propose a two level system. Google would offer a free, slow service (256 to 384 Kbps), whilst the Earthlink service would be fee based but faster (1Mbps in both directions). The companies would share the cost of deployment and operation. The powerful SF Metro Connect alliance (IBM and Cisco Systems, together with SeaKay), has also submitted a bid for the San Francisco contract. It is believed that this also has free access provision. Other proposals have been submitted by Communication Bridge Global, MetroFi, NextWLAN and Razortooth Communications. San Francisco is not the first US city to launch a citywide WiFi project. Philadelphia, Anaheim (both EarthLink projects) and some other major cities have also done so and it is expected that about 25 major US cities will have been “unwired” in the next two years. Although these are largish cities, they are generally far smaller than London (San Francisco has a population of less than 1 million people). New York City is closer in size to London, with a population of just over 8 million people and has an enthusiastic group of Councillors advocating the construction of a citywide WiFi system. However, the free marketer Republican mayor, Michael Bloomberg, believes that a private sector group should set up a system, if it is needed. He has, therefore, been placing obstacles in the way of efforts to implement a community run operation. Discussions have been going on for over three years and the only progress has been the introduction of a City Council Bill to set up a task force to investigate the matter. Bloomberg’s hope of a private sector WiFi solution for NY City has not produced any firm response from companies. EarthLink has stated that it was “theoretically” interested, but would prefer to have the city as a partner. Not all influential people in the USA agree with the stance of the NY Mayor. Two Bills were recently introduced into the US Senate to allocate more of the available RF spectrum to community use. Whilst the NY citywide WiFi scheme may only be crawling slowly forward, a London scheme has yet to even get to the public discussion stage. There is a great danger that the enormous opportunity presented by the 2012 Olympic Games for setting up a London-wide WiFi/WiMax system will be lost. The advertising possibilities open to any organisation, such as Google, willing to put such a system into London by 2012 would more than compensate for the large initial cost. Thus, London is in a good position to get a very good deal, but only if it moves in time. http://www.earthlink.net/about/press/pr_san_francisco_network/ America Online and Yahoo have announced that they intend to introduce a preferential email service. They intend to offer privileged treatment to companies which are prepared to pay for the delivery of email messages. The internet companies allege that the preferential service will help them identify legitimate mail and cut down on junk mail. Presumably, all unpaid emails will be defined as junk mail. This perception is reinforced by the intention of AOL to allow preferential emails to bypass its spam filters and to delete links & images from most unpaid messages. The new proposals seem to offer very little advantage to bulk email senders (the prime target) over the far cheaper, fixed fee services already provided by other companies. Of course, one suspects that the new proposals are all about the huge additional revenue AOL and Yahoo will generate – if they succeed in their ploy. The principle of net neutrality states that network owners should remain neutral with respect to the content they carry. There has not been any outright dissent from this principle. However, AOL and Yahoo seem determined to ignore it. Additionally, executives at three of the largest US network operators (BellSouth, AT&T and Verizon Communications) have also suggested that large content providers should pay extra for priority use of their networks. The idea that service quality levels should only be guaranteed at a price has caused the US Consumers Union, the Consumer Federation of America and Free Press to call on Congress to enact net neutrality legislation. The US Senate has started taking evidence and a Google executive has argued forcefully against the suggested changes to current practice. If
the companies proposing the changes are successful, it is to be expected
that other internet companies will then follow suit and the free
services currently available will become progressively worse and
worse until they are finally discontinued. There is no doubt that
a great blow will have been delivered to the vision of the open world
wide web which was generally accepted such a short time ago. More

Feb 06 This year will see the beginning of the end for MicroSoft’s Windows XP operating system. On the last day of 2006, MicroSoft will stop supporting WinXP Home - it says. Support for WinXP Pro, the more expensive version, will continue until 2011. There is some doubt about whether MicroSoft will actually carry out its published program, as it has failed to live up to past, similar declarations concerning Win98. After “several stays of execution”, MicroSoft now intends to stop issuing new patches, updates and fixes for Win98 on 30/06/06 and to remove the self help pages from its website one year later. It probably means what it says about support for Win98 this time. After a life of eight or nine years, it is reasonable to retire Win98. However, the original retirement dates were obviously determined by MicroSoft’s income requirements rather than any great market need. The retirement dates of WinXP are again being driven by cash generation considerations – the release of Windows Vista (formerly Longhorn) is expected to be announced in the autumn, with availability aimed at Christmas 2006. The major specification improvements promised for the new version are greatly improved security and, for gamers, 64 bit operation. Providing that the applications running on an operating system are performing well, there is no great urgency to upgrade. Most current application software still supports Win98 and, of course, all of it that is aimed at the Windows system (rather than the Mac or Linux systems) supports WinXP. However, it is not absolutely necessary to ever upgrade Windows, one could simply change to Linux, at no cost. Free versions of the Linux, such as Mandrake and Centos (Community ENTerprise Operating System) can be downloaded. These are based on the Red Hat Linux source code - quite legally, as Red Hat is released under the standard Linux GNU Public Licence and they are regularly upgraded, just like other operating system software. If the Linux operating system is coupled with Open Office , Mozilla's Firefox browser and Grisoft's AVG antivirus package, 95% of software for a good home PC can be obtained free. There may be a very small cost for a business PC, but it would be insignificant compared with continuing to use Windows. More

Jan.06 An
interesting report from the European Interactive Advertising Association
was issued at the end of 2005 which compared the popularity of the
different types of media on offer in Europe.
Microsoft has joined the Open Content Alliance (OCA) and Yahoo, to become a rival to Google (see Google Flexes Muscles ) in the scramble to digitise the world's libraries. As result of the collaboration, Microsoft will launch MSN Book Search next year. Other contributors to the OCA initiative include Adobe Systems, Harvard University, The Royal Botanical Gardens at Kew, the Smithsonian Institution, the UK National Archives and York University. MSN Book Search will also deliver results from academic libraries, periodicals and other print sources, putting the service in direct competition with Google. One of the first significant outcomes from the Microsoft initiative is an agreement with the British Library to digitise its out-of-copyright collection and to provide search facilities for it. During 2006, it is expected that 25 Million pages (100,000 books) will become available on the internet from the British Library. This is only a small part of the British Library collection, but the project is expected to continue beyond 2006. Of course, the Gutenberg project (see Books on Line ) has been making available on the internet out-of-copyright books for many years and public spirited authors have been increasingly bypassing the publishing houses by simply uploading their books onto websites. The new developments bring to bear the enormous resources of Google & Microsoft and this should ensure that progress will very rapidly accelerate. More

Dec 05 OpenOffice
2.0 Has Arrived - Free! As a direct competitor to Microsoft’s Office suite, OpenOffice has the overwhelming advantage of being FREE to download. In common with Microsoft’s offering, the OpenOffice package is large (75MB). Downloading via a broadband connection is therefore a practical proposition but doing so via a dialup connection would probably be a little difficult. Very cheap CDs of OpenOffice are often available and provide an alternative to downloading. Microsoft has a near monopoly position in general office software used in library services and this is an unhealthy situation. Should not OpenOffice be seriously considered at the next upgrade? Choosing Microsoft is the easy option – it does not require any thought. However, this used to be the situation with IBM computers and now they are just one of the many that are in the market place. Why should the situation be different for software? Download & more

Nov. 05 Google is stirring up hostility from the publishing world by extending its search technology to the world of books. Its new Google Print venture is intended to do for the print medium what it has done for the internet i.e. to point the user to the source of information in print. This idea was originally received by academic librarians with some enthusiasm (Oxford, Stanford, Harvard & Michigan universities have agreed to open their collections to Google), as the resources that Google can employ are enormous and this would obviously be, potentially, a great help in research tasks. The New York Public Library has also opened its collection to Google. Books in English were the first Google Print target and it has already run into opposition from the (hidebound?) book establishment. The US Guild of Authors and three authors are suing Google for breach of copyright. Google believes that it has no case to answer, as what it is doing comes within the fair use definition, and it is pressing ahead with its program by expanding beyond the US / UK sources. Oxford University and the N.Y. Public Library have avoided the wrath of US authors by limiting Google’s access to documents that are out of copyright. It is difficult to see how Google’s activities can be other than an advantage to the vast majority of genuine authors i.e. authors who have created original material. However, there are a small number of reference book compilers who may be able to show that scanning their works is a breach of copyright. By embarking on a legal fight with Google over the interpretation of copyright law, authors could be opening Pandora’s box. Copyright laws are very much more generous to authors than patent laws are to inventors and there is a school of thought that suggests there should be relaxation of the copyright rules. A high profile copyright legal fight may well open up the discussion. One of the leading critics of copyright law, Lawrence Lessig, a professor at the Stanford Law School, has suggested that one cannot accept the activities of the various internet search engines as being legal without accepting that similar scanning is also legal for print media. Alternatively, the converse argument may be true. If the scanning of books is illegal for the purposes of providing source information, the traditional activities of internet search engines are probably also illegal. It looks as though the action by the US authors strikes at the very roots of the internet. Having upset the US Guild of Authors, Google then went on to join up with Sun Microsystems to create a software business that could prove a great threat to the worldwide domination of Microsoft. Microsoft’s Office suite market has been suggested as a likely target for the new group. It is some time since Microsoft has had a strong competitor, so it too is likely to be a little miffed. Finally,
Google has proposed setting up a free, citywide WiFi system in San
Francisco. This will upset yet another set of business people. Google
will use its usual advertising method of funding for the new venture.
Could this be the way forward for London? AT Oct.05 Londoners are to be offered an ADSL2+ internet access service in October. This type of service will provide broadband access speeds up to 18Mb/s+. The new offering will not come from BT, which has been testing a similar scheme, but from Be and UK Online. The cost of the new service is expected to be between £20 and £30 per month. BT is concentrating on rolling out its 8Mb/s service across the country and did not expect a full UK roll-out of ADSL2+ for some time. Another new service for Londoners, which started operation this month, is a broadband wireless one from UK Broadband. The speed range of this service is 256kb/s (cost £10/month) to 1Mb/s (cost £18/month). Further information: http://www.ukonline.net , http://www.ukbroadband.co.uk AT,
Sep 05 The IFA tradeshow in Berlin during the first week of September was the showcase for two new developments which could prove to be significant milestones on the road to practical, mass-market electronic books. The first development is a 8GB 1 inch hard drive which provides a storage density of 105 GB per square inch. This Hitachi device is also claimed to consume 40% less power than its predecessor and to be highly shock resistant. The 1 inch Hitachi drive is 5 mm in height and 13 grams in weight. So, it is very suitable for electronic products intended to be carried in pockets. The low power requirement and good shock resistance are also considerable advantages for this type of application. The next size up from the 1 inch drive is the 1.8 inch format. The increase in diameter (the height is still 5mm) has enabled Hitachi to make a 30GB drive available now and to promise a 60GB drive in early 2006. These new drives would provide sufficient storage capacity for a small to medium library of books, providing that there are only a limited number of photographs present in those books. The second development is a flexible display called the Readius. This has been produced by Polymer Vision, a spin out from Philips in Eindhoven. When not in use, the screen is rolled up and the overall size of the product shrinks to 100mm x 60mm x 20mm, approximately 1/3rd of the size of an average paperback book. However, when required for use, the device unwinds to provide a 4.8 inch (122mm) paper-like display. The display is monochrome and uses the bistable E-Ink technology. The lack of colour is not really a great drawback for text, but the bistable nature of the display is a great advantage, as it would allow small batteries to be used. This is the same technology that is used in Sony's e-book reader, LIBRIe, which was launched approximarely 18 months ago (see EBOOKS ) Mass availability of electronic book readers, based on these and similar developments are still a few years away, but it is only a few years. When people have the capability of carrying around hundreds of books in their pockets, what will be the function of public libraries? Further

VERSUS WINDOWS COSTS The first report, “TCO for Application Servers: Comparing Linux with Windows and Solaris”, states that the TCO of a Linux application server over three years is $40,149 compared with $67,559 for Windows and $86,478 for Solaris. These totals include costs associated with transferability of administrator skill and hardware architecture portability, in addition to the immediate installation costs. Other benefits that Linux bestows are the flexible licensing model of Linux and its compatibility with a broad range of hardware platforms. The second report, “Beyond TCO: The Unanticipated Second Stage Benefits Of Linux”, considers the skill based benefits of using Linux. IBM suggests that Linux is very popular with IT staff and especially with young IT staff. The reason for this is the great support for Linux in universities and colleges. Thus, graduates leave university with a good knowledge of Linux and recruiting them tends to be easier for organisations employing the system. Their managers also find the flexibility of the open source model an advantage. Further information: http://www-1.ibm.com/linux/competitive/solarisToLinux.shtml AT
Sep 05 LAPTOPS ARE
FOR HOLIDAYS AS WELL AT, July 05 Public library internet provision is sometimes criticized as being predominately used for email. Whilst there is nothing wrong with this use, a recent survey suggests that the popular view may become outdated, if it is not now. The Pew Internet & American Life Project, 2005 has found that adult internet activities can be broken down as follows:
Of course, this is an American survey and will not translate exactly to the UK. However, the UK usually follows where the US leads, so the survey can be used as an indication of the near future in this country. As the three most popular internet activities are surely also those which would be at the top of the list in any public reference library in the UK, the survey results should not be a great surprise. Perhaps there is something for the supporters of public library reference collections to worry about though. The search for DIY information was found to go well beyond the expected home improvement and gardening themes. The advantage of the internet as a very broad source of information is clearly an important factor here. More information: http://www.pewinternet.org/ AT, June 05 INTERNET – THE NEXT GENERATION There are two developments slowly creeping up on internet users. They have both been around, in theory, for some time and are now becoming practical propositions. They each, of course, have the obligatory acronym without which it would be impossible for the internet community to take them seriously - IPv6 and ADSL2+. Internet Protocol version 4, IPv4, has been in existence for a very, very long time. It provides the method of defining a unique address for the huge number of internet users that exist worldwide and now is being superseded by IPv6. The main reason for the change is that there are simply too many hosts on the internet and IPv6 provides an increase from 4 to 16 bytes (32 to 128 bits) for use in the address. The migration of dial-up internet users to wideband internet use has resulted in these users changing from temporary holders of IP address numbers (automatically allocated by their internet service provider) to permanent holders of an IP address. The efficiency with which the available addresses are used has, therefore, declined at the same time as the overall use of the internet is increasing. Without the changeover to IPv6, this would be a recipe for disaster. It may seem rather strange that the Internet Protocol version following version 4 should be version 6. Just as telephone system planners did not realise that they would eventually run out of telephone numbers, the internet planners were slow to understand that the same could happen on the internet. Thus, the IPv5 designation was allocated to a parallel development called the Internet Streaming Protocol before the potential problem was recognised. With the introduction of IPv6, the internet user will not normally notice any difference in operation when he/she goes online. At least, that is the hope/expectation. However, there have been some problems reported. For instance, Microsoft’s Internet Explorer has been found to be unable to resolve domain names (the www.xxxx name) to IPv6 addresses for some servers. Whilst the objective of the IPv6 change is simply to keep the internet operational, the objective of ADSL2+ is to improve performance. Most people who have a broadband internet connection actually utilize ADSL (asynchronous digital subscriber line) technology and it allows a download rate of 1 or 2 Mbit/sec & an upload rate of a few hundred kbit/sec to be achieved – a significant improvement on the speeds available with a dial-up connection. That this transmission rate is fairly reliably accomplished on a basic POTS (plain old telephone system) copper network of the order of 100 years old (in London) is astounding. That there should be plans to accelerate the transmission rates by a factor of 10 to 20 seems unbelievable. However, the International Telecommunications Union (the international body overseeing telecommunications standards) approved the ADSL2+ standard in Jan 2003 to do just that. The infrastructure upgrade necessary to meet the ADSL2+ standard will, no doubt, be something that BT will carefully control. However, ADSL2+ has been designed to be backward compatible with existing ADSL equipment, so there should be a seamless changeover to the new system, as far as the user is concerned. London, with its large population concentrated within 4 to 5 km of local exchanges and mostly within 2km, will probably be the first large scale deployment of ADSL2+ in the UK, although this is likely to be preceded by several small pilot trials. The 2km distance is important, as that is the present limit for achieving the maximum data rate transmission. BT has only recently completed upgrading its telephone exchanges to make available standard ADSL service to virtually the entire UK population. So why should it start immediately on another round of upgrades? The answer is that it makes good commercial sense. With the higher transmission rates of ADSL2+, it is possible to simultaneously carry high definition TV (HDTV) broadcasts, internet data and internet phone calls over that POTS network that BT owns. The internet data transmission business has, over the past few years, become an important profit earner for BT and it expects that HDTV & VoIP (voice over the internet protocol – internet telephone calls) will become just as profitable. So, when ADSL2+ has been fully rolled out, we will be able to look forward to a future of stable internet technology, where everyone will be know what is on offer and everyone will be able to get it. Well no, not quite. There are already plans to increase transmission rates beyond those of ADSL2+. Look forward to the VDSL standard where rates increase to 30 to 100 Mbits/sec.

This workhorse version of removable storage has fallen victim to the improving reliability and decreasing cost of CDs. The floppy disc cannot compete with the cost per MB of a CD and, with the high demand for image storage devices, it is unable to deliver the required storage capacity. It is useless as a system backup storage device. Nevertheless; it has given excellent service and is far more rugged than its predecessor 5.25 and 8 inch diskettes. There are, of course, other manufacturers of 3.5 inch floppies. However, Sony has declared the death of the medium and it will not be long before it is buried. We all need to plan for that event by transferring must-keep data to CDs. The next PC purchased is unlikely to have a 3.5 inch floppy disc drive – some, corner-cutting versions don’t have them now. In the recent past, the reliability of CDs has caused concern with data becoming irretrievable after only a few months of storage (see CD Problems & CD Problems Revisited, below). However, it is now clear that, provided the user is careful with his / her labelling (the adhesive on some labels and the ink in some felt-tip pens attacked the CD) and does not live in the Amazon rainforest (fungal growth was an occasional problem), CDs will provide a useful data storage life. The length of that life depends on the type of CD used. If long storage life is the criterion for choosing a CD, the CD-R type is obviously preferred over the CD-RW type (why pay more for the ability to overwrite data). The cheapest CD-R discs are constructed by sandwiching a cyanine dye between a transparent polycarbonate main body and a reflective aluminium foil layer. The writing laser burns pits into the dye through the polycarbonate plastic to record the ones and zeros of the data. These pits can then be read by a low power laser which does not alter them. With this construction (recognisable by its bluish or blue/green tinge), it is claimed that a data storage life of 10 – 70 years is achievable. The longest life for CD data storage is claimed for CDs which use a phthalocyanine dye with a gold reflective foil. The foil, seen through the transparent dye, gives the disc a golden colour and this also reflects the high cost. This type of CD has a claimed data storage life approaching 100 years. Between the two extremes, there are two other types which give a better life than the cyanine / aluminium type but not as good as the phthalocyanine / gold type. These are formazan dye, gold foil type (light green colour) and metallized AZO /silver foil type (dark blue colour). Remember to keep the CDs vertical and protected from dust.

However, by 2012, Wifi use will have expanded far beyond its present rather limited employment. Most new laptop computers have a Wifi capability and people are becoming more and more familiar with its use. Taking into consideration the fact that most of the visitors coming to expensive London will have to be fairly affluent, the demand for Wifi services can be expected to be great. Provision will have to be improved and there is a place for public libraries in the plan. Hopefully, the outrageously expensive British Library scheme (£4.50/hour for normal use and 50p/min for help) would not be considered to be the model. AT May 05 The internet did not loom very large in the recent UK general election. However, analysis of the US Presidential election in 2004 now indicates that it could become another potent source of political comment. The BuzzMetrics and Pew Internet & American Life Project report “Buzz, Blogs and Beyond: The Internet and National Discourse in the Fall of 2004" compared political blog activity with that of other media in the last stages of the US Presidential election. Influence and “buzz generation” (buzz generation = amount of simultaneous talk) was also compared. The study considered 40 sites (16 conservative blogs, 16 liberal blogs and 8 general blogs). Conservative bloggers made 6,716 unique posts, the liberal bloggers wrote 7,151 entries; and neutral blogs had 4,251 unique posts between 27 September and 31 October, 2004. The researchers allocated chatter on political message boards and forums to one of the conservative/liberal/general categories and found that there were 984,549 unique conservative posts, 947,503 liberal posts and 98,963 neutral posts in the period. Campaign releases and official blogs generated by the two political parties were monitored and it was found that there were 955 Republican messages and 835 Democrat messages. The US public does seem to have taken the opportunity to make its voice heard above the noise from the political parties and may well pose a future threat to the power of the media barons. If the US experience can be replicated in this country, democracy will be strengthened. The opportunity for the public to make its views heard directly, rather than via a media/government filter should act as a counter to apathy. The danger is that the party political machines may try to highjack the new outlet and thus damage its credibility. The Labour party has been found to have used party activists to append their names to template and other biased letters to local newspapers. These supported party policy without acknowledging the party affiliation. It would be just as easy for the political parties to use this underhand technique on the internet. However, the technology exists to simply and quickly search for common phrases or other groups of words over a wide range of websites. The template nature of such internet messages would then become obvious, as would the original source. Not only would the practice quickly become public knowledge, but it would become self defeating.

AT May 05 WIKIPEDIA
USE SURGES Wikipedia is usually simply described as a free on-line encyclopaedia, but it is also popular as a source of news items. Although news items are more ephemeral than the traditional contents of an encyclopaedia, it is advantageous to have them grouped in one place. The background to the news items can then be looked-up very easily. The open source Wikipedia is now proving to be more popular than the commercial general reference websites such as Answers.com and Encarta. Wikipedia achieved a traffic rate (market share) of 3.84% compared with 1.9% for Answers.com and 1.81% for Encarta. However, the most popular website in the overall reference category is Dictionary.com with a traffic rate of 4.46%. More Information: www.hitwise.com , www.wikipedia.org AT May 05 IBM has designed a small unit which is intended to help people with hand tremors to use a computer mouse. It has granted a licence to a small UK company, Montrose Secam Ltd., to manufacture the unit. At less than £70, incl VAT, the unit is affordable by most libraries and represents a significant improvement in the service that can be offered to a segment of the community which is often ignored.

On 24th February a US report was released
which suggested that 2005 might be the year that broadband power-line
technology (BPL) becomes a realistic third option for BPL operates in a similar way to that
of DSL and cable. The signal is carried The current BPL speeds are 500 kilobytes to 1 megabyte per second, although some of the world's major modem producers are developing technology allegedly capable of 100 megabytes per second. Unsurprisingly, urban areas are expected to provide the main market for BPL. The Washington based New Millennium Research Council report concluded that consumer and regulatory issues are by no means insurmountable. BPL is not being ignored in Europe. The telecom standard organisation, ETSI, carried out laboratory tests and the French electricity supply company, EDF, carried out field tests on medium and low voltage networks at a site just outside Paris in November 2004. The electricity supply companies are not yet completely convinced that providing communication systems for the public is a good commercial proposition. However, they can see great benefits in using the technology to manage their networks. More information: AT Mar 05 MORE on BPL The inclusion of these electronics industry heavyweights in the group suggests that powerline communication systems are now being taken very seriously, at least in the USA. There appears to be only one UK member of the group – Pace, the set-top box manufacturer. AT Sep 05 A recent market survey by Janco Associates has shown that the Mozilla Foundation’s Firefox browser has become the second most used browser in North America with 4.48% of the market. Of course, this is a long way behind MicroSoft’s Internet Explorer (84.85%). However, Mozilla can claim that every user of its product made a deliberate product choice – something that MicroSoft cannot claim, due to its past bundling policy. Although the Firefox market share is miniscule compared with that of Internet Explorer, it is still impressive - Firefox was only upgraded from the beta version in November. Even more encouraging for Mozilla is the fact that Firefox is the only widely used browser which is increasing its market share. The rapid growth in market share of Firefox has been mainly driven by the “blogger” community where its market share is a very respectable 35%. This suggests that there is much more growth to come for Firefox, as knowledge of it leaks out into the general population. The “also rans” in the browser race are Netscape (3.03%), AOL (2.20%), MSN (0.58%) and Opera (0.34%). MicroSoft does not have a history of tolerating competition and another study, by Gartner, concludes that the software giant will respond to protect its market position. It certainly was not slow to do so in its war against Netscape. Ironically, the destruction of Netscape by MicroSoft is responsible for the creation of the Mozilla suite of Firefox (web browser) and Thunderbird (mail client). One of the last acts of Netscape as an independent company was to make available to the open source community the Netscape source code and Mozilla has built on this. Version 1 of the Thunderbird email client was released in December 2004 and is a direct competitor of MicroSoft’s Outlook Express. In the first month after its release, two million downloads of the software were made. The advantages of Thunderbird over Outlook Express are far faster operation and an inherently cross platform product (the open source legacy). More details: AT 02/05
The way that the internet scene is developing in the USA is of particular interest to the UK, as there is a tendency for the UK to follow the same path. A survey carried out by International Demographics found that the US growth in internet use has changed direction. Young people were the initial driving force but, in the last four years, internet growth has been dominated by people who are over 55 years old. AT, Dec 04 Mobile phones are disruptive and annoying in a library environment and most public libraries are plastered with notices asking people to turn them off. These requests are comprehensively ignored and the nuisance goes on. Most library staff seem to have given up making an effort to enforce the rule, just as the police have opted out of enforcing the law on using cell-phones while driving. So, the mobile phone has taken over and there is nothing that we can do about it. Well, not quite. QuinetiQ, the defence research organisation, has perfected the manufacturing process for a wallpaper that will screen out the mobile phone signals. This process prints a frequency selective metal pattern onto either flexible or rigid substrates using far fewer production stages than would be necessary at present. It is therefore very cost effective. The next time that a library needs to be refurbished or built, it would be a good idea if this type of wall surfacing was included in the specification. Of course, there would have to be consideration of the radio-frequency leakage effect of windows. However, the new process can be used on rigid substrates, so it is probably extendable to glass. Even if it was not, the technology of incorporating metal patterns in glass is already well established for car window heaters and adhesive, transparent screening films are available. Just think. All those notices asking people to turn off their mobile phones could be replaced by notices telling them that they are entering a mobile phone quiet area – there would probably be a queue to get in. One side effect of screening a library from mobile phone signals is that any wireless local area network set up in that library could be made inaccessible from outside – usually considered to be a good thing. Further information: THE FUTURE OF PUBLIC LIBRARIES At a Developer Forum in Frankfurt recently, Tim Johnson of UK research company Point Topic suggested that broadband internet use is growing at a faster rate than mobile telephone use ever managed to achieve. He said that the present estimate is for 150 million broadband lines to be installed by the end of 2004 and that South Korea is the country leading the change to broadband use with 24% of the population having this type of internet access. The Ofcom April 2004 broadband connection figure for the UK is 3.99 million (2.45 million DSL connections + 1.54 cable connections). Comparison with the South Korea figure is difficult, as it is not clear from the Ofcom data how many people use each broadband connection in the UK on average. However, Ofcom states that 15% of homes have broadband, so it is reasonable to suppose that the UK cannot be very far behind South Korea. BT has frequently been cast as the villain in the broadband story. It has been accused of deliberately delaying conversion of telephone exchanges in order to obtain a commercial advantage. However much truth there is (or was) in the accusation; it is becoming irrelevant, as 84% of UK homes and businesses now have the DSL service available and this will soon (summer 2005) be improved to 99.6% of all households. Although the cable availability map overlaps the DSL one, the actual overall broadband availability will be slightly higher. Even those homes a long way from an exchange may soon be able to benefit from a broadband connection, as BT begins 500kb/s ADSL trials over 10km lines. Next year, the telephone exchange conversion program will be virtually complete and it is obvious that the government deadline of all homes having broadband capability (if required) by 2008 will be met. It only remains for the potential users to be persuaded that high-speed internet access is worth the money. Once the infrastructure is in place and paid for, there will be an enormous pressure on the service providers to maximise the utilisation of that infrastructure. Thus, it is to be expected that the cost of a broadband contract will continue its downward slide and the services provided will be expanded further. This view of the future is not restricted to the writer. During its recent, first Investment Analyst Conference, Ofcom stated: “By the end of the decade, the successful introduction of greater infrastructure competition combined with continued innovation in access technologies, could enable a majority of UK households to benefit from affordable and accessible broadband connections delivering video-quality bandwidth” [i.e.very wide bandwidth]. The question arises as to how this changing situation will affect London’s Library Services. In the short term, there probably will not be much of an impact. There will be a continuing need to provide a computer literacy education program and to ensure that internet access is not exclusively for the affluent. Lending of books, CDs etc will go on as before. In the long run, when hardware and on-line access costs have reached a very low level, the public internet access facilities now provided by public libraries will be of small value to the community and their popularity will wane. Further, the computer literacy initiative will have worked its way through that part of the adult population reachable by such a program (the children are and will be covered by school programs). At best, there will be a small residual requirement for on-line access for visitors to the capital and a minority of residents. The People’s Network will have done its work and will probably need to be retired. Long term developments in the range of services provided on-line and new hardware designs are likely to have an increasing impact on the core library activities that are, at present, not seen to be related to computer use. Probably the first areas to be affected will be the CD / DVD hire activity. With fast download, 24/7 availability and a vast catalogue to choose from; the on-line businesses will have major advantages over any high street operation whether in the public or private domain. Added to this advantage is the inherent low overhead cost applicable to the on-line businesses. It is just possible to see the beginning of this shift in market position with the pain now being experienced by traditional record shops. The more volatile part of the record industry, i.e. the pop record part, is suffering badly now, but the classical end is just as vulnerable in the long term. The record industry may well succeed in combating copyright infringement. However, this will do little to help the high street record shop – the die is cast and public libraries will not be immune. Once it is accepted that the contents of CDs can be obtained more easily and more cheaply via the internet than from a public library, it becomes clear that all associated electronic media will eventually also fall into this category. Thus the public library video tape and DVD collections, which have been so enthusiastically built up, will become wasteful space fillers from an income generation viewpoint. At some point, it will be necessary to decide whether to remove these items from the selves or to remove the charges. If removal from the shelves is the preferred option, will books be substituted? There are many electronics development projects still in the research phase which will accelerate the trend already identified and these will eventually come to bear on all core public library activities. In the very long term, even the book lending activity will not be immune from radical change. Speaking at the recent Public Library Authority Conference; Lord McIntosh, the Libraries Minister, stated “Books are here to stay because people want them and they will be a key element in the library service in the foreseeable future.” It is true that books are very popular at present, but one should ask why this is before assuming that they will continue to be so. After 500 years of printing development, books have become relatively cheap, convenient, easily obtainable and easily used containers of information (factual and fictional) i.e. it is the currently preferred delivery method for most detailed content. If an improved delivery method becomes available, it is inevitable that it will replace the currently preferred one. The research is underway in many parts of the world in preparation for this new product type. There is little doubt that Library Services, over the next few decades, can be expected to change out of all recognition. Interesting times? More details: AT E-BOOKS In particular, the range and quality of displays is improving fast. It is still not possible to find a commercial, portable display which can match the resolution available from good quality printing on good paper but, after less than half a century development, it is possible to believe that this standard will be achieved in the short to medium term. This should be compared with the half a millennium required to reach this quality level by the print industry. Late April will see the introduction of Sony’s e-Book reader, LIBRIe. This utilizes the Phillips / E Ink “electronic ink technology” to give a monochrome display with a resolution of approximately 170 pixel per inch (similar to newsprint). Although this resolution is not high, it has certainly proved to be acceptable to millions of newspaper readers throughout the world. The real advantage of the LIBRIe display technology is the fact that it is non-volatile i.e. it only requires to draw electrical power when changing the display contents. This mitigates the second problem associated with the electronic book concept, the poor power density available from current batteries. High power density batteries are a prime requirement for a successful e-book machine, as the reader must be light-weight and easily handled. Although a considerable research effort is underway to solve this problem, commercialisation of the results has not yet materialized. The LIBRIe’s power source is made up of four cheap, widely available, standard AAA batteries, which is sufficient to read 10,000 pages. One inherent advantage of the e-book concept is the number of books that can be carried by one person – a fallout from the intense development effort that was aimed at improving computer storage technology. The LIBRIe can store 500 downloaded books. The range of books commercially available is continually increasing and, with programmes such as the Gutenburg Project (see below) dedicated to increasing the availability of digital books, there is no doubt that there will be sufficient content to justify the LIBRIe’s storage capacity. There have been several false starts in the e-book area and it is just possible that this new entrant will be another one. However, it is clear that each new entrant moves a step closer towards the ideal product and eventually there will be a product that is sufficiently close for the public to enthusiastically use it. If the experience of similar products is repeated, when that happens, the switch is likely to be very fast. This has profound implications for publishing, book retailing and libraries of all kinds. The mess that the recorded music business has got itself into by ignoring technical developments would pale into insignificance, if the book world followed suite. More information: AT April 04 One of the problems with implementing a community WiFi system is the short range obtainable with the standard antennas available for the IEEE 802.11 a/b/g specifications. This is now being addressed by Intel and other companies as they carry out development of components designed to meet the provisions of the new standard IEEE 802.16a. WiFi was originally intended to only give communications over a relative small area such as offices or cafe hotspots. However, the potential for more universal use was quickly recognized and many community-wide schemes have been successfully set-up. These have needed careful design in order to overcome the inherent limitations of the WiFi specifications. The new WiMax standard is intended to provide greater range and bandwidth than the existing WiFi specification. Potentially, IEEE 802.16 equipment will give transfer data rates up to 70 Mbit/sec over a range of 30 miles. This has to be compared with 11 / 22 / 54 Mbit/sec over a range of 2 miles (say). Intel has a test system operating from the roof of its Santa Clara headquarters which has received data from a distance of 12 miles. WiMax, when it becomes available in 2005, will allow the copper / fibre optic “last mile” connection to be replaced with wireless for broadband internet use. This will be of great interest to ISPs (internet service providers) that are frustrated by the slow conversion of BT’s exchanges to broadband use. The designers of IEEE802.11 equipment are also busily seeking ways of improving performance. Motia's smart antenna design is claimed to extend WiFi range by up to four times and the Atheros variable bandwidth (channel bonding) technology will allow data rates to rise to 108 Mb/s. The potential for Library Services to extend their public access internet service is obvious. With WiMax, a 24 /7 service does become economically possible. More details: http:/ | ||||||||
