A Brief History of the Future

July 11, 2009 by Roy Johnson

readable account of computer and Internet development

This is a fascinating history of the Internet – but given a personal spin. Journalist and academic John Naughton describes the technology of the digital revolution from a user’s point of view. What are the concerns of the average person? How does it all work? At each stage he explains the significance of each development. This approach will be very reassuring for beginners. A Brief History of the Future starts with potted biographies of Vannevar Bush, Norbert Weiner, and J.C.R Licklider as his version of ‘fathers of the Internet’, but it is Paul Baran and Vint Cerf who he tips as most important of all – because they came up with the ideas which pulled it all together.

A Brief History of the Future Naughton is good as explaining the details of the technology and engineering, and he puts his professional journalism skills to good use. Whenever necessary, he uses analogies with practical, everyday matters – such as packet-switching being like moving a house and its contents in separate trucks which take different routes to their destination, and then are re-assembled at the other end. He also writes amusingly about the pleasures and perils of email, and takes a refreshingly tolerant view on the issues of censorship and control.

There are some parts of the hard technical developments which he leaves out of his account – politely admitting that he has done so. This seems to me a wise choice, because the type of popular readership at which the book is aimed will welcome his focus on the personal achievements and his own enthusiastic account of engineering history.

Some of the other accounts of the Internet such as Hafner and Lyon’s Where Wizards Stay up Late and Robert Cringley’s Accidental Empires occasionally tax the non-specialist reader in this respect.

Like these other books, his narrative becomes chronologically scrambled at times, maybe because this reflects the disparate locations, enterprises, and time schemes [not to mention funding and government enterprises] involved in the enterprise. Naughton goes out of his way to be scrupulously fair to them all – including even monopolies such IT & T – which like British Telecom put a brake on the development of the Internet for a long time.

There is a particularly interesting chapter on the development of the UNIX operating system, and an explanation of how and why the Usenet News system evolved from it. He also provides interesting introductions to topics such the development of Linux and the Open Source movement which belives that software should be available free of charge.

He is at his best when describing the development of hypertext and the World Wide Web – perhaps because the story flows in an unbroken chronological sequence from Vannevar Bush, via Douglas Engelbart and Ted Nelson, through to Tim Berners-Lee and Marc Andreesson. He ends with a brief glimpse at the current dangers of the commercialisation of the Net and the reasons why it is almost impossible to predict its future.

Naughton offers a very readable, humane, and contagiously enthusiastic account of the Net and its major features. This is a perfect book for anyone who wants to know the background to this major technological revolution.

Accidental Empires

June 13, 2009 by Roy Johnson

Amusing history of computers and the Internet

This book has two sub-titles: ‘The Triumph of the Nerds’ and ‘How the boys of Silicon Valley make their millions, battle foreign competition, and still can’t get a date’. You can see that Robert Cringely takes an irreverent attitude to his study of Internet history and computer development in the US. He looks at it in terms of business enterprise, scientific development, and as a collection of extraordinary and eccentric characters who were once skipping classes and are now running the shop.

Internet historyHis account is written in a breezy, amusing, self-deprecating style. He jumps around from one topic, one character sketch, and even one decade to another. One minute he’s tracing the history of software development, the next it’s business methods and biographical sketches of entrepreneurs. Much of his energy is spent on critiques of Chairman Bill and figures such as Steve Jobs and Steve Wozniak.

It’s a sort of history of how it all happened – but rendered via a cubist form of narrative in which you have to reassemble the chronology yourself. Cringley is a computer magazine gossip columnist, and I’m afraid that ultimately, it shows.

What he offers is popularised science, via sound-bite journalism: “it takes thirty years, more or less, to absorb a new information technology into daily life”. These little aphorisms are sometimes amusing, but they’re just as often slightly silly, as in the basic statements on which he bases his claims for the entire book.

First, that the Internet happened more or less by accident. Second, that the people who made it happen were amateurs. Neither claim is actually true, but it suits his purpose to amuse. However, the moment you stop to think about these propositions, they evaporate immediately.

cringely-3And yet for all that he takes a jokey line, he offers lots of interesting insights – such as the reasons why some software lasts, unlike hardware which on average is replaced every three years. It’s a shame, because he is clearly well informed and at some points has interesting things to say about technological developments and even the philosophy of the internet – but his efforts are dissipated by a lack of focus. He throws off ideas and sketches topics every few pages which warrant a book in themselves, but he can’t quite make up his mind if he’s a historian of technology or a commentator on business methods.

The last two chapters are a 1996 update [made for a successful TV adaption] in which he admits the rise to power of Microsoft – but this is more business management history than an account of technological development.

The good side of Cringeley’s approach is that he offers a bracingly irreverant account of the US computer business which might encourage readers to take a sceptical view and not be overawed by Big Names. The downside is that his analytic method is anecdotal, and hit-and-miss. There is here the beginning of what I think will eventually make a fascinating study – the history of software development. Perhaps he ought to get together with a disciplined co-author [or an editor with Iron Will] and he could produce something more coherent and persuasive.

Amazon Hacks

100 Industrial-Strength Tips and Tools

This book tells you how to get information from Amazon; how to contribute reviews, recommendation lists, and product advice; how to sell stuff; how to make money as an affiliate; and how to harness the power of Amazon’s enormous database using tools they will provide – all for free! There are now lots of opportunities to sell, auction, and broker goods at Amazon. It’s like being in eCommerce with all the headaches taken out.

Amazon Hacks Paul Bausch tells you how to do it – using Amazon’s marketplace and Zshops systems. The first part is about how to use and make contributions to the ‘Amazon community’ – how to submit book reviews, make reading suggestion lists, and send gifts to your friends. All of this can be done straight away, with no waiting or steep learning curves. The second part is how to sell through Amazon – which you can do by marketing what you have, or finding out what other people want. And this is either by straight sales or by auctions.

Next comes the affiliates programme, whereby you get a commission for every customer you send to Amazon – so long as they make a purchase. Some people have established full time jobs on the strength of this scheme. It’s fairly simple, and all the steps are explained.

The last part of the book is an account of Amazon Web Services. These are free advanced tools and programs they offer for data recovery – XML, PHP, XSLT, databases, and SOAP. All the coding necessary for embracing these hacks is included.

Because Amazon lists everything about you – the books, CDs, or whatever you have bought or wish to sell – and because they allow you access to this information – you can even call up listings of products onto your own web site. This includes both what you want to sell, but it can also include lists of what other people want to buy.

Amazon are exploring innovations in eCommerce, even making their databases available to potential competitors. I suspect that anyone who follows all the opportunities offered here could make profits from these new departures.

If there is one small drawback, it’s that he doesn’t discuss the criticisms which many affiliates level against Amazon. They seem to offer more and more opportunities, yet squeeze the bonuses tighter and tighter. It’s a cat and mouse world where clever entrepreneurs have to stay one step ahead of the game. But at least you can try it all out for free!

This is a book which will appeal to Amazon users, anyone who deals in books, music, and all the other products which Amazon retails – and in particular those who would like to join Amazon affiliates and need help in getting set up.

Being Digital

July 11, 2009 by Roy Johnson

why computers are important – now and in the future

Nicholas Negroponte is professor of the Media Lab at MIT and an enthusiastic spokesman for the revolution in information technology. He writes regular columns in WIRED, which have been expanded to form this manifesto for the future of digitisation. The fundamental thesis he expounds in Being Digital is simple but profound. He suggests that the revolutionary state we now inhabit is one in which the ‘bit’ is to be distinguished from the ‘atom’.

Being DigitalThat is, information encoded and transmitted electronically in binary form needs no material existence, whereas its physical realisation in print, film stock, or VCR is earth-bound and cumbersome. The bit can be transmitted instantly, globally, and virtually cost-free, whereas its tangible version in atoms immediately requires physical production, distribution, and storage. The future, he claims, is digital.

In the course of a dozen and a half short chapters he covers just about every aspect of modern communications. Developments in data compression; the next stages in desktop publishing; how the television monitor and the PC will merge; ownership and intellectual property rights.

He is particularly interesting on multimedia, [whose origins he reveals in the Israeli attack on Entebbe airport!] CD- ROMs [described as “the Betamax of the 90s”] the historical development of GUIs, and the politics of those businesses which are busy buying up information for “repurposing”.

En passant he covers holography, teleconferencing, speech recognition, virtual reality, and howPCs will develop. There’s something here for everybody.

As far as Negroponte is concerned everything is bits. For with digitisation, any one medium becomes translatable into another. A book chapter is no different from a video clip once it has been transposed into binary code (except that it takes up less space). The future of PCs for writing he sees being affected by miniaturisation, touch-sensitive screens, and “intelligent agents” which will learn to interpret our demands. All this is delivered in a breathless telegraphic style (which I suppose befits his subject) and he is deliberately provocative and cryptic in a manner which suggests that many of his ideas could be developed further.

It’s easy to spot the contradiction that this electronic vision comes to us in a form which he wittily describes as “ink squeezed onto dead trees”. In fact the book is produced on paper of such poor quality that you can read the print on both sides at once. [It’s not clear if this is a high-tech device or an ironic comment from the publishers.] In addition, for someone extolling the transmission of data in milliseconds, Negroponte does a lot of travellers name-dropping. One wonders why he has to go traipsing round the globe so much when he could do business using Email. But he has tips for travellers: boycott those hotels which don’t let you plug your laptop straight into the wall.

The persuasiveness of what he has to say arises from his own first-hand experience. As someone who has been in the business of computers and multimedia since the 1960s [whilst Bill Gates was still at school] he is well informed about the history of its technology, frank in revealing the true ownership behind corporate names, and generous in attributing credit for the technical advances we all now take for granted. However, if you can steel yourself against his breathless rush, one or two of the arguments can be made to tremble a little with some applied clear thinking.

He supposes for instance that writers would earn more if their work were distributed digitally (smaller profits, bigger sales). But would you want to download then print off a 500 page book to avoid the publisher’s price-tag? (This is already possible from databases such as Project Gutenberg.) Why have your edition of Moby Dick on 600 loose sheets of A4 when Penguin will supply a bound copy for less than the price of a gin-and-tonic? Nevertheless, this is just one small idea amongst many that he throws off in a series of elegantly catenated chapters.

Others ideas might be more disturbing for those professionally engaged in existing forms of communication – but they make sense when measured against common experience. This is what he has to say about manuals for instance. “The notion of an instruction manual is obsolete. The fact that computer hardware and software manufacturers ship them with product is nothing short of perverse. The best instructor on how to use a machine is the machine itself.” This is bad news for technical writers, but do you really refer to that 900 page manual any more? Of course not: you just click on HELP.

This is a stimulating and thought-provoking book, and unless Negroponte has it all wrong (which seems doubtful) it will provide ideas for the rest of us to work with for many years to come. Anyone who wants a glimpse into the future should start here.

Blown to Bits

June 18, 2009 by Roy Johnson

business strategies and the new technology

This book seeks to explain how technological developments are impacting in the world of eCommerce. We’ve all heard about the IT revolution, but where is it actually having an effect? Evans and Wurster start with the cautionary tale of Encyclopedia Britannica, whose business model was wrong-footed when Encarta was launched on CD. A strategy almost two hundred years old was overturned in the space of five years. You can now buy Britannica on disk for the price of a paperback book. The lesson is that it’s suicide to rest on your laurels when faced with new technology. Their second major point is what they call the playoff between ‘richness’ and ‘reach’.

Blown to BitsYou can either deliver information-rich data to a few people, or lightweight general ads to many. These appear to be mutually exclusive strategies – though Amazon manage to do both at the same time. They are essentially IT optimists, because they believe that access to information will promote more efficient competition. “the emergence of universal, open standards will … accelerate the demise of hierarchical structures and their proprietary information systems”. Whether this is true or not is still a matter for e-Commerce conjecture.

In the era of the IT revolution, the knowledge we need to enrich information is available to us all – free of charge. Therefore, as they argue, “Shifting the trade-off between richness and reach melts the informational glue that bonds business relationships”.

As you can see, you have to be prepared for a mode of expression which combines abstractions and the jargon of business and management studies:

This shaped the horizontally integrated multidivisional corporation, held together by a logic that transcended the business unit.

I’ve read that statement several times, but I still don’t know what it means. It’s hard to stick with this kind of opaque and abstract language. But if you can, it’s worth it – because they do deal with important general principles – though it’s a great relief when they occasionally come to discuss a practical example.

They look at newspapers and banking as examples of business models which are now vulnerable to the new technology. For instance, those people who use personal banking systems are small in percentage terms, but they are the richest, and account for 75% of banking profits. What does this mean? It means that banking is vulnerable to changes brought about by software engineering.

They explore that buzzword of the new e-Commerce – ‘disintermediation’ (the removal of the middle man) using the example of online shopping. Yet no sooner has the middleman gone than he comes back again as the ‘navigator’ – that is, somebody who acts as a guide and as an advisor amidst the plethora of choices available to the consumer.

The general lesson boils down to this. Access to information and the transforming power of new technology puts traditional business methods under threat: yet at the same time it opens up new possibilities for those wishing to take them.

This book has become a set text on an Open University technology course that I teach. The students find it hard going, but all of them in my group have grasped the ideas behind it – and finished the course with successful Web essays outlining eCommerce plans.

Cascading Style Sheets

July 4, 2009 by Roy Johnson

explanation – by the guys who invented them

What are cascading style sheets (CSS)? Answer – “a simple mechanism for adding style (fonts, colors, spacing) to Web documents”. If you have spent any time at all wrestling with HTML code, trying to control the layout and appearance of text on a page, you will know one thing. It’s an almost hopeless task. What looks good in Netscape might be a dog’s breakfast in Internet Explorer, and it will probably look even worse in Opera. The same would be true of more recent browsers such as FireFox and Google Chrome.

Cascading Style SheetsAs Lie and Bos explain: “HTML doesn’t pay much attention to the document’s appearance” – so CSS offers “a simple language that can be read by humans”. It’s basically another system of coding which can be added to .htm pages which allows the author more control over the physical appearance of what’s on the page. It also begins the process of separating appearance from content. They start with an introduction to basic HTML (which they claim can be learned in less than a day!) before describing CSS in all its detail. This is where any normal user will encounter the first difficulty – because the code is defined in a relentlessly arbitrary jargon – of ‘selectors’, ‘declarations’, ‘properties’, and ‘values’.

Then they go on to describe the variety of ways in with a style sheet can be ‘glued’ to a document. This fortunately offers the user more than one way to achieve a particular effect. But there’s no escape from the abstract style:

Recall from Chapter 1 that an attribute is a characteristic quality, other than the type or content of an element. In that chapter we discussed the attributes HREF, SRC, and ALT. In this chapter we will discuss two new attributes that have been added to all HTML elements to support style sheets

But what it lacks in accessibility, it makes up for in thoroughness, and fortunately, the book is very well illustrated. They cover all the features of this mini-technology which Web designers are likely to require – fonts, spacing, layers, colours, and the tricky issue of forward compatibility. They describe the issues of cascading and inheritance which advanced users might wish to exploit. I would have liked to see the page code for some of the wonderful examples they reproduce in full colour, but at least they show what CSS can do.

Style sheets may well become more popular as the early generations of browsers which didn’t support them fade into the ancient history of the Web [that is, anything more than five years old]. If you’re interested in exploring the possibilities of CSS, then you might as well get the story from the guys who invented the idea – and make sure you buy the latest (third) edition, which contains a useful comparison of browser-support. As the HTML standard is developed to keep pace with browsers in their latest versions, this is a book with a bright future.

Cascading Style Sheets

July 9, 2009 by Roy Johnson

complete explanation of style sheets for web designers

This is the second edition of Eric Meyer’s best-selling guide to cascading style sheets. It covers CSS1 in impressive depth, and cautions readers quite frankly about some the problems of the still immature CSS2. Style sheets are the solution to the one big limitation of HTML. They allow authors to control the appearance of what’s on the page, leaving the HTML code to describe the content and its structure – which was its purpose in the first place.

Cascading Style Sheets The original guide to CSS, Cascading Style Sheets, produced by its inventors Hakon Lie and Bert Bos, is thorough and well illustrated, but it’s written in a very dry manner. Eric Meyer manages to make his account more readable, and more easily digestible for those who will need it. His ‘definitive guide’ is organised in logical sections which discuss what can be done with fonts, colour, the appearance of text, and layers – which is the introduction of a third dimension to what appears on screen.

He explains the many ways of creating colour – with a humane description of the mind-bending hexadecimal system. Then he deals with the complications of length units, the arrangement of text on the page (using spacing, justification, decoration, and alignment) and the way in which fonts and the appearance of text can be controlled.

He goes into a lot of detail on the manner in which fonts are rendered – their family, size, weight, attributes. The same is true on backgrounds. It’s a pity that O’Reilly have decided to limit the book illustrations to white, grey and black – because the topic is crying out for colour illustration.

Sometimes there are extended descriptions of what CSS tags will do, when an illustration would have been more useful, but he explains which elements are ‘deprecated’ – that is, ‘in the process of being phased out’ from the HTML Specification.

CSS also allows authors to get ready for the eventual move from HTML to extensible markup language (XML) so it’s worth learning about style sheets if the current enthusiasm for XML is going to last. There are some amazingly complex effects described which involve background images and negative positioning – pushing graphics off the screen.

You have to be prepared to embrace another set of jargon – declarations, elements, selectors, properties, pseudo-elements, values, specificity, and inheritance – but no doubt these terms will become familiar.

There are also three useful appendices – an annotated list of resources, a complete list of CSS1 and CCS2.0 properties, a sample style sheet, and a list of browser support. O’Reilly have occasionally been criticised for calling so many of their manuals ‘the definitive guide’ – but in this case there’s a good case to say the title is fully justified.

Content Syndication with RSS

June 26, 2009 by Roy Johnson

Sharing headlines and information using XML

Content syndication means making headlines and information from one web site available for distribution to any others that want it. This is done technically by using RSS, which stands for RDF Site Summary, Rich Site Summary, or Really Simple Syndication. If you need to go all the way, RDF stands for Resource Description Framework. Ben Hammersley first of all explains the separate standards which have arisen, taking them in chronological order.

Content Syndication with RSS Then he describes the software which has been written both to generate RSS feeds, and to receive and read them on screen. There’s also a short XML tutorial, as well as a list of useful sites and resources. Unfortunately there are two camps of competing standards, each with two current versions – rather like the early days of the browser wars.

Fortunately he covers them all in his description of how to use RSS and what it does. The separate standards are complex in their differences, and he obviously belongs to one of the rival camps promoting them; but he is even handed in his treatment, and gives them all comprehensive coverage.

Much of the book is rather technical, with pages full of coding; but anyone familiar with HTML or XML will feel pretty much at home.

He gives fully written out examples of pages in each of the standards. As in strict XML, there is a complete separation of style and content. This is because the recipient might be reading the news feed as part of a blog, on on a PDA, or even as a text message.

RSS is sprouting all over the Web at the moment. Wherever you see one of the small buttons saying “News Feed” or “XML Feed”, you have the ability to receive information from that site. And of course it’s all free.

This publication is aimed at web developers and web site authors who want to share their site with others by offering RSS-based feeds of their content. It’s also for developers who want to use the content that other people are syndicating. As usual with O’Reilly publications, the presentation is impeccable.

Content: Copyright and DRM

December 2, 2009 by Roy Johnson

Selected Essays on Technology, Creativity, Copyright, and the Future of the Future

Cory Doctorow is a young Canadian freelance writer and web entrepreneur who lives in London. He’s an editor of Boing-Boing and former director of the Electronic Frontier Foundation; he writes science fiction novels, and he gives his work away free of charge – yet makes a living from his writing. How can it be done? That’s one of the things he explains here. Content: Copyright and DRM is a collection of speeches, essays, and articles he has produced in the last few years, proselytising in favour of open source software, against digital rights management (DRM) systems, against censorship, on copyright, and in favour of the free exchange of information, unhindered by state controls or commercial prohibitions.

Content: Copyright and DRMAt their most fervent, his arguments come across like those of a students’ union activist – but he’s brave. He speaks against Digital Rights Management (DRM) to an audience at Microsoft. The reason he’s a successful journalist is that he understands new media technology, and he has a gift for wrapping up his arguments in a vivid and succinct manner:

Books are good at being paperwhite, high-resolution, low-infrastructure, cheap and disposable. Ebooks are good at being everywhere in the world at the same time for free in a form that is so malleable that you can just pastebomb it into your IM session or turn it into a page-a-day mailing list.

He has a racy and amusing journalistic style. He writes in short, almost epigrammatic statements with a no-holds-barred attitude to any potential opposition.

As Paris Hilton, the Church of Scientology, and the King of Thailand have discovered, taking a piece of [embarrassing] information off the Internet is like getting food colouring out of a swimming pool. Good luck with that.

Some of the items are quite short – quick reprints of web pages from the Guardian technology section – but they are all pertinent to the issues of creativity and new media. Why for example does the best eCommerce site in the world (Amazon) want to control what you do with your Kindle downloads? Doctorow argues that these are short-sighted policies which prevent the spread of information and the creation of new developments.

He’s gung-ho about the business of eBooks and eCommerce. He makes his books available free as downloads on the Internet, confident that this will result in more sales of the printed book. There’s no actual proof that it results in more sales – but he’s happy with the results, and so is his publisher, and the publicity gives him income from other sources, such as journalism and speaking engagements.

Having said that, more than 300,000 copies of his first novel were downloaded for free, resulting in 10,000 printed books sold. As he argues, that’s like thirty people picking up the book and looking at it in a bookstore for every one who made a purchase. But the thirty pickups cost almost nothing, and I think many authors would be very happy with sales of ten thousand.

[It should be remembered that the average full time writer makes approximately £3,000-5,000 a year – and if you look at that in terms of a forty hour week, it’s less than £2.50 per hour.]

The sheer range of his subjects is truly impressive. There’s a chilling insider report from a committee discussing DRM, an essay on a sub-genre of science fiction writing called fanfic, and even a satirical piece calling into question the limitations of meta-data.

He’s at his strongest on the subject of copyright – and that includes the rights of the person who buys the book, the film, or the MP3 music file. The author has the right to be paid for selling it to you, but you have the right to do with it (almost) whatever you wish.

He has any number of interesting things to say about the nature of eBooks – from their apparent problems, their multiple formats, and their malleability, to the issues surrounding copyright. And the encouraging thing is that he writes not just in theory but as a working writer who is exploring the eBook business and what it can do – for both authors and readers.

If you want to know what’s happening at the sharp end of digital publication and new ideas about the relationships between authors and their readers – do yourself a favour and listen to what he has to say. You might not agree with it all, but it will give you plenty to be thinking about.

CSS Cookbook

July 17, 2009 by Roy Johnson

quick solutions to common style sheet problems

Style sheets take all the slog out of designing the appearance of your web pages. No more fiddling with the code in a multitude of pages: just fix the font size, the line spacing, the page width or the size of headings in one file, the style sheet, and that will apply across your whole site. This is a guide to what is possible using the latest specification (2.1) of style sheets, written by Christopher Schmitt – one of the endless number of expert authors O’Reilly manage to locate.

CSS CookbookIt’s aimed at people who want to make a start with style sheets, or who are grappling with their problems and need quick fix solutions. It assumes you know the basics of web design using standard HTML markup, but he does keep the relationship between the two clearly in mind:

As a design language, CSS is focused on presentation, which includes helping web developers control the layout of their pages. HTML tables and other elements, on the other hand, are tools you use to mark up content. The ideal is to have HTML represent the structure of the content as an intellectual abstract level and CSS say how to present it for a particular device.

The presentation couldn’t be simpler. First a problem is specified (You want to indent the first line of a paragraph) and then he shows the CSS code to achieve it, followed by an illustrative screen shot. There’s an explanation of how and why it works as it does, and there are web links to online tutorials and official specifications directly related to that topic.

Each chapter considers one element of a web page that style sheets can control – the font, the page, links, lists, forms, tables, and how to create print-friendly pages.

He shows some of the new effects possible with the latest CSS version 2.1 – creating collapsible menus and tabbed folders, designing forms without using tables, controlling the appearance of content held within table cells, and creating multi-column pages holding the content in place with the very useful float property.

One of the hardest parts of learning about style sheets so far as I am concerned is the language in which it is expressed. It’s a pity there’s so much abstract terminology. Even at intermediate level it’s difficult to grasp immediately statements such as this:

Because these properties aren’t passed to child block-level elements, you don’t have to write additional rules to counter the visual effects that would occur if they were passed.

He finishes with some nifty tips, tricks, and workarounds. How to create a print-friendly style sheet for instance. This removes all the decoration and navigational graphics from a web page to produce something that is comfortably readable when printed out. All this without changing one bit of the page markup.

There’s also a useful appendix listing discussion groups, web resources, downloadable software, and ready-made CSS templates. Like everything else in this book, these take you quickly to solve problems of design.

The latest edition of this book is a hugely enlarged resource – more than double the size of the first. It’s been expanded to include much more information for CSS learners, explaining topics that range from basic web typography and page layout to techniques for formatting lists, forms, and tables. For more advanced users it has also been updated to take into account the behaviour of CSS in the latest versions of web browsers, including Internet Explorer 7, plus Firefox and Opera. You can’t get much more up to date than this.
