Web 5.0 "The Fourth Shaker"


Sean Carton is one of our longest-running and smartest columnists. His mission is to stay one step ahead of the curve covering the latest in Web and advertising technologies. That's why his column is called The Leading Edge.
So it came as no surprise to get this cutting-edge news alert today from his way-ahead-of-the-curve agency, Baltimore-based idfiveidfive Discovers Web 5.0, Declares it “The Fourth Shaker”
Baltimore-based digital communications firm idfive (www.idfive.com) announced today the discovery of “Web 5.0,” a previously unknown evolution of Web technology that promises to revolutionize how both consumers and businesses communicate online.
“We’re freakin’ blown away by the implications,” exclaimed Producer Ted O’Mera in his characteristic tone of indiscriminate enthusiasm, “This changes absolutely everything. Everything. Heck, I just learned PHP. Now this. I think I need a nap.”[the rest after the jump]
While most Web firms are still trying to come to grips with the slippery meme known as “Web 2.0,” idfive’s discovery promises to catapult them past their competition, providing them with insights, capabilities, and buzzwords that others can only dream of. “Yeah, Web 2.0 is a big deal right now,” comments Sean Carton, Chief Strategy Officer of idfive, ”But so what? Web 5.0 is going to make Web 2.0 look like Web 1.0. Or something like that.”
While Web 2.0 reportedly grew out of a combination of technologies and buzzwords that combined social networking with user generated content and the ability to employ AJAX (Asynchronous Javascript and XML) to allow real-time interaction with data from within the browser, Web 5.0 moves beyond the browser to encompass a range of technologies and acronyms that had never before been used in computing, data display, or interaction.
idfive acknowledges that the concept of Web 5.0 is quite obviously too complex for all but a few of the world’s most eminent digerati and best selling cyber-celebrities to understand. However, in their ongoing desire to educate the public, they want it known that the basics should not be hard to grasp for anyone with a basic knowledge of quantum physics, koi farming, and hyper-dimensional topologies. At this point idfive is still carefully exploring Web 5.0 (or “5-Space” as they’ve termed it), but are ready to reveal some of the basics of their discovery.
At its heart, Web 5.0 is based on the KABOOM (Knuth-Moris Asynchronous Binary Object Oriented Metadata) archi-tecture, itself an evolution of OXY-CLEAN (Optimal Xor-gate Yultide Computational Emotion Analysis Nondeterminism) technologies. Taking advantage of n-space disparities that arise out of multiplexed qubit transmission inherent in most quantum computers, Web 5.0 actually manages to transcend so-called “consensus reality” in order to hyperspatialize information into matrices composed of Higgs Bosons. The result is a Web of information so info-dense, so googapixel packed, so socially interconected that it defies conventional definitions of what “the Web” means.
“We are only now beginning to grasp how this previously undiscovered technology will allow us to optimize synergies within the Metaverse, allowing us to create holistic, team-based paradigms that leverage true holomovement for the first time,” explains Sean Carton. “Connecting realms both metaphysical and quantum-mechanical, this technology will allow for high-bandwidth transmission of data clusters using true random-access packets that, for the first time, allow for unequalled collaboration, social interaction, entanglement, and perhaps even pizza delivery that truly takes less than 30 minutes or it’s free...in complete safety and with total information security.”
idfive plans on immediately deploying Web 5.0 technologies for their clients, allowing them to provide a service un-equalled in the crowded field of Baltimore Web development. In fact most idfive clients are already enjoying the benefits of Web 5.0 since idfive has been deploying the new technology for no extra charge while in their “stealth phase.”
“This is some amazing stuff. We bring screaming death to all previously established paradigms. All your Web belongs to us,” exclaims Multimedia Director Sean Cohen. “We PWNED all you utha Web punks!”
idfive plans a public rollout of Web 5.0 sometime in Spring 2007. Unfortunately this technology is so advanced that no computers currently exist with the capacity to display its powers. “But don’t worry,” cautions Carton, “Web 5.0 is already here. Time to play catchup, all you ‘Web 2.0’ companies!”
“Yeah,” underscores Claire Rusko-Berger, idfive Director of Client Services, “It’s Web 5.0, dumbass!”
Thanks, Sean. We needed that!

Google, with the cooperation of prestigious libraries, has been digitizing books to make them findable. The practice excites futurists but angers some publishers. Of necessity, digitization creates virtual copies. The publishers claim that such duplication violates copyright, even if the book’s content is hidden from the public. The New York Public Library, one of Google’s partners in the project, recently hosted a public debate on the subject.
It was while attending that debate that my discomfort with the hype surrounding an emerging genre of web development turned into a full-blown hate-on.
The big room was packed. There were more ticket holders than chairs. Yet the seat in front of me remained empty. Each time a hopeful standee approached the empty chair—and this happened every few nanoseconds—the poor schmoe seated next to it had to apologetically explain, “Sorry, the seat is occupied.”
It soon became clear that the kindly schmoe was reserving the seat, not for a friend or colleague, but for a stranger who had imposed that duty on him. While the kindly fellow defended the other man’s throne against a steady stream of resentful ticket holders, the stranger was off somewhere knocking back the library’s free champagne. I wondered what kind of jackass would ask someone he didn’t know to save his seat for thirty minutes at an oversold event. When he finally arrived, I found out.
A taste of ass
“Were you at the Web 2.0 conference?” the arriving man asked, by way of thanking the other for saving his place. The kindly schmoe signified in the negative. This was all the encouragement our man needed to launch into an adjective-rich and fact-poor monologue that was loud enough for half the room to hear.
It soon appeared that “Web 2.0” was not only bigger than the Apocalypse but also more profitable. Profitable, that is, for investors like the speaker. Yet the new gold rush must not be confused with the dot-com bubble of the 1990s:
“Web 1.0 was not disruptive. You understand? Web 2.0 is totally disruptive. You know what XML is? You’ve heard about well-formedness? Okay. So anyway—”
And on it ran, like a dentist’s drill in the Gulag.
At first I tolerated the pain by mentally modifying the famous scene from Annie Hall:
HIM: “I teach a venture capitalist workshop, so I think my insights into XML have a great deal of validity.”
ME: “Oh, really? Because I happen to have Mr. Bray right here.”
Later I gnawed my knuckles. At some point, in a kind of fever, I may have moaned. Blessedly, at last the lights dimmed and the night’s real speakers redeemed the evening.
But the ass whose braying I’d endured left a bad taste.
Less noise, more signal
Let us now define and disclaim.
The jerk at the library event was in love with his own noise, and the problem with noise is that it interferes with signals. What is the signal? What, if anything, does “Web 2.0” mean? What is the good thing that the hype risks obscuring?
Well, there are several good things, it seems to me.
Some small teams of sharp people—people who once, perhaps, worked for those with dimmer visions—are now following their own muses and designing smart web applications. Products like Flickr and Basecamp are fun and well-made and easy to use.
That may not sound like much. But ours is a medium in which, more often than not, big teams have slowly and expensively labored to produce overly complex web applications whose usability was near nil on behalf of clients with at best vague goals. The realization that small, self-directed teams powered by Pareto’s Principle can quickly create sleeker stuff that works better is not merely bracing but dynamic. As 100 garage bands sprang from every Velvet Underground record sold, so the realization that one small team can make good prompts 100 others to try.
The best and most famous of these new web products (i.e. the two I just mentioned) foster community and collaboration, offering new or improved modes of personal and business interaction. By virtue of their virtues, they own their categories, which is good for the creators, because they get paid.
It is also good for our industry, because the prospect of wealth inspires smart developers who once passively took orders to start thinking about usability and design, and to try to solve problems in a niche they can own. In so doing, some of them may create jobs and wealth. And even where the payday is smaller, these developers can raise the design and usability bar. This is good for everyone. If consumers can choose better applications that cost less or are free, then the web works better, and clients are more likely to request good (usable, well-designed) work instead of the usual schlock.
Of this they spin
In addition to favoring simpler solutions built by leaner teams, the stuff labeled “Web 2.0” tends to have technological commonalities.
On the back end, it is most often powered by open source technologies like PHP or (especially) Ruby on Rails.
On the front end, it is mainly built with web standards—CSS for layout, XML for data, XHTML for markup, JavaScript and the DOM for behavior—with a little Microsoft stuff thrown in.
When web standards with a little Microsoft stuff thrown in are used to create pages that can interact with the server without refreshing, the result is web apps that feel peppy and, dare we say it, Flash-like. In a white paper that actually got read, writer/consultant Jesse James Garrett named what I’ve just described. He called it AJAX, and the acronym not only took, it helped interactivity powered by these technologies gain traction in the marketplace.
Here is where the spinners bedazzle the easily confused. Consider this scenario:
Steven, a young web wiz, has just celebrated his bar mitzvah. He received a dozen gifts and must write a dozen thank-you notes. Being webbish, he creates an on-line “Thank-You Note Generator.” Steven shows the site to his friends, who show it to their friends, and soon the site is getting traffic from recipients of all sorts of gifts, not just bar mitzvah stuff.
If Steven created the site with CGI and Perl and used tables for layout, this is the story of a boy who made a website for his own amusement, perhaps gaining social points in the process. He might even contribute to a SXSW Interactive panel.
But if Steven used AJAX and Ruby on Rails, Yahoo will pay millions and Tim O’Reilly will beg him to keynote.
Who weeps for AJAX?
We pause but a moment to consider two AJAX-related headaches.
The first afflicts people who make websites. Wireframing AJAX is a bitch. The best our agency has come up with is the Chuck Jones approach: draw the key frames. Chuck Jones had an advantage: he knew what Bugs Bunny was going to do. We have to determine all the things a user might do, and wireframe the blessed moments of each possibility.
The second problem affects all who use an AJAX-powered site. If web signifiers and conventions are still in their infancy, then AJAX-related signifiers and conventions are in utero. I am still discovering features of Flickr. Not new features—old ones. You find some by clicking in empty white space. This is like reading the news by pouring ACME Invisible Ink Detector on all pieces of paper that cross your path until you find one that has words on it.
I am not knocking Flickr. I love Flickr. I wish I were as gifted as the people who created it. I’m merely pointing out complex design problems that will not be solved overnight or by a single group. In Ma.gnolia, which is now in beta, we used small icons to indicate that additional actions could be taken and to hint at what those actions might be. We succeeded to the extent that 16px by 16px drawings can communicate such concepts as “you may edit these words by clicking on them.”
These problems and others will be solved, most likely by someone reading this page. One points to these issues mainly to dent a swelling of unthinking euphoria. We have been down this road before.
Bubble, bubble
When I started designing websites, if the guy on the plane next to me asked what I did, I had to say something like “digital marketing” if I wanted to avoid the uncomprehending stare.
A few years later, if I told the passenger beside me I was a web designer, he or she would regard me with a reverence typically reserved for Stanley-Cup-winning Nobel Laureate rock stars.
Then the bubble burst, and the same answer to the same question provoked looks of pity and barely concealed disgust. I remember meeting a high-rolling entrepreneur in the early 2000s who asked what I did. I should have told him I hung around playgrounds, stealing children’s lunch money. He would have had more respect for that answer.
I hated the bubble. I hated it when Vanity Fair or New York Magazine treated web agency founders like celebrities. I hated that mainstream media and the society it informs either ignored the web or mistook it for a high-stakes electronic version of the fashion industry.
When the bubble burst, these same geniuses decided the web was of no interest at all. Funny, to me it was more interesting than ever. To me it was people and organizations publishing content that might not otherwise have seen light. It was small businesses with realistic goals delivering value and growing. It was traditional publishers finding their way into a new digital medium, helped by folks like you and me. It was new ways of talking and sharing and loving and selling and healing and being. Hardly dull.
Eventually the uninformed stopped seeing a wasteland and started seeing bloggers, by which they meant only those bloggers who wrote about politics, most often from the extreme left or right. The web was “back” even though it had never left. (Of course, the fifth time you hear Wolf Blitzer say “blogger” or ask, “what do the bloggers have to tell us about these still-unfolding events?” the joke is stale and you wish those who don’t get the web would go back to ignoring it.)
But nothing, not even the rants of political bloggers, was as exciting as the scent of money. As the first properly valued “Web 2.0” properties began to find buyers, a frenzy like the old one popped hideously back to life. Yahoo spent how much? Google bought what? Here was real blood in the water.
But how to persuade the other sharks in the tank that this blood feast was different from the previous boom-and-bust? Easy: Dismiss everything that came before as “Web 1.0.”
It’s only castles burning
To you who are toiling over an AJAX- and Ruby-powered social software product, good luck, God bless, and have fun. Remember that 20 other people are working on the same idea. So keep it simple, and ship it before they do, and maintain your sense of humor whether you get rich or go broke. Especially if you get rich. Nothing is more unsightly than a solemn multi-millionaire.
To you who feel like failures because you spent last year honing your web skills and serving clients, or running a business, or perhaps publishing content, you are special and lovely, so hold that pretty head high, and never let them see the tears.
As for me, I’m cutting out the middleman and jumping right to Web 3.0. Why wait?

Tips & Trik
Lindungi Mata dari Radiasi Komputer!
Dewi Widya Ningrum - detikInet

Jakarta, Mata merupakan salah satu aset yang paling berharga sehingga harus dijaga benar kesehatannya. Keseringan melototin monitor komputer bisa membuat mata menjadi lelah.

Tahukah Anda bahwa radiasi gelombang elektromagnetik yang ditimbulkan komputer bisa mengganggu kesehatan? Studi yang dilakukan American Optometric Association (AOA) mencetuskan bahwa radiasi komputer dapat menyebabkan kelelahan mata dan gangguan mata lainnya.

Kebanyakan gejala yang dikeluhkan responden adalah soal kelelahan mata, pandangan menjadi kabur dan mata kering. Masalah visual lainnya yang timbul adalah soal gangguan sakit kepala dan sakit leher atau bahu.

Nah bagi Anda yang sering nongkrong di depan komputer, lindungi dan rawatlah mata Anda dari radiasi yang ditimbulkannya. Berikut beberapa tips yang bisa dilakukan untuk menghindarinya.

1. Pakai pelindung layar komputer (filter) untuk mengurangi radiasi yang ditimbulkan komputer.

2. Pilih layar komputer yang radiasinya rendah, seperti layar LCD (liquid crystal display).

3. Jagalah jarak pandangan mata dengan monitor. Idealnya, jarak minimum antara mata dengan monitor komputer adalah 45 cm.

4. Sesuaikan posisi layar komputer dengan mata, jangan ketinggian dan jangan terlalu rendah karena bisa menyebabkan sakit leher. Selain itu, jika monitor terlalu tinggi dari pandangan mata maka akan menggangu pasokan udara yang disuplai ke otak. Sebaiknya layar monitor diposisikan sejajar dengan pandangan mata.

Menurut American Optometric Association (AOA), seperti dilansir Rctimes, untuk mencegah kelelahan mata sebaiknya tempatkan monitor dengan posisi yang ergonomis. Monitor harus ditempatkan pada posisi 16-30 inci dari mata, tergantung seberapa besar layar. Umumnya posisi yang nyaman untuk menatap monitor adalah 20 hingga 26 inci.

5. Sesuaikan pencahayaan monitor dengan intensitas kenyamanan mata.
Brightness yang terlalu terang atau terlalu buram tidak baik bagi kesehatan mata. Pencahayaan yang terlalu terang akan membuat mata menjadi silau, sedangkan pencahayaan yang terlalu buram hanya dan membuat mata bekerja lebih keras untuk melihat. Hal ini akan membuat mata menjadi cepat lelah. Untuk itu, cobalah sesuaikan brightness dan contrast monitor hingga mata Anda bisa melihat dengan nyaman. Jangan lupa juga untuk menyesuaikan resolusi dengan karakter di monitor agar dokumen-dokumen mudah dibaca mata.

6. Istirahatkan mata sejenak.
Jangan terus-terusan melototin layar komputer. Usahakan sediakan waktu beberapa menit untuk mengendorkan dan mengistirahatkan mata Anda. Ini akan mengurangi kepenatan mata dan otot. Segarkan mata dengan cara memandang ke ruangan lain atau memandang indahnya langit biru atau tanaman hijau.

7. Seringlah mengedipkan mata demi menghindari mata menjadi kering.
Jarang mengedipkan mata akan membuat mata menjadi kering. Karena itu sering-seringlah mengedipkan mata, karena dengan berkedip maka mata akan mengeluarkan air mata yang akan menyebar ke seluruh permukaan kornea untuk menjaga mata tetap lembab dan jernih.

8. Pakailah kacamata dengan lensa khusus untuk komputer. Seperti pernah diberitakan, ahli masalah mata (Optometrist) Dr. Jay Schlanger mengatakan beberapa perusahaan kini mulai membuat lensa yang bagian atasnya dirancang untuk melihat komputer, dan bagian bawahnya untuk membaca.

Pengguna lensa kontak juga punya solusi, yaitu dengan mengganti lensa kontak generasi baru yang terbuat dari silikon hydrogel. "Silikon jenis ini memungkinkan daya transmisi oksigen yang lebih tinggi dibanding jenis lain," ungkap Schlanger.

9. Perbanyak konsumsi vitamin A agar mata tetap dalam kondisi baik.

10. Jika merasa mata mengalami gangguan, segera pergi ke dokter mata untuk meyakinkan bahwa mata Anda benar-benar sehat. (dwn/dwn)
