Amazon Kindle – Vision og forretning

Who's afraid of Virginia WoolfHvad er en Amazon Kindle
Amazon Kindle er en kompakt enhed der minder om en computer, men er beregnet til at vise tekst, f.eks. digitale bøger – eBøger/eBooks, på en skærm der bruger en teknologi der hedder eInk. Denne teknologi adskiller sig fra traditionelle computerskærme, ved at den danner billedet med magnetisk blæk, og at skærmen virker med reflekteret lys, som papir, oplevelsen minder derfor meget om papir, og i øvrigt gør det at enheden bruger meget mindre strøm, da det kun er når billedet dannes på skærmen at der bruges strøm, den relativt langsomme opdateringshastighed skærmen arbejder med, gør at man ikke kan vise ting som video.

Kindle har en 6″ skærm med en opløsning på 800×600 punkter, dette giver en meget tydeligt skærm, som skal ses før man tror det. Teknikken gør dog at skærmen ikke kan vise farver, men det er noget der bliver arbejdet på det, og netop i dag afholdes der en konference i Frankrig, hvor der efter sigende er rigtig mange brugere af de nye eBogs læsere.

I denne artikel, som nok bliver en artikelserie, vil jeg fokusere mere på visionen bag, så der er ikke rigtig tale om en anmeldelse, og alle de steder der står Amazon Kindle, kunne der lige så godt stå noget andet, f.eks. “Tölva” – som en fremtidig enhed kunne hedde – “tilfældigvis” er det netop det jeg har kaldt min Kindle 😉

Hvorfor!
Så hvorfor købte jeg en Kindle? Først og fremmest så var jeg så heldig at få en i hænderne til reboot11, og jeg ønskede mig straks en, så da Amazon annoncerede at Kindle ville bliver lanceret internationalt, trak jeg straks et nummer. Den officielle lanceringsdato var den 18-oktober, den blev sendt den 19-oktober og jeg havde den den 22-oktober, hvilket inkluderede en nat på DHLs lager – den moderne internationale handels evner til levere imponerer mig altid.

Visionen
Den virkelige grund til at jeg anskaffede en Kindle, var nu også at jeg længe har haft et erklæret ønske om at læse noget mere, og her synes jeg Kindle giver os et glimt af fremtiden. Bøger og aviser er utroligt “upraktiske”, jeg glemmer dem, synes de er uhandy og tunge, og dette gælder også paperbacks – jeg føler at det er en af grundende til at jeg ikke læser så meget som jeg selv ønsker. Nå ja, jeg er jo glad for dimser, og da Nikolaj Sonne fra “So Ein Ding” så min Kindle til Copenhagen Cocoa Development Camp et par dage efter jeg havde fået den, stoppede han helt op midt i sin “procedure”, jeg havde en Kindle før Mr. Ding himself.

Når jeg ser en Kindle tænker jeg i øvrigt iPod anno 2001. Kindle er ikke rigtig en dims (gadget – savner dansk ord), det er en platform. Som iTunes og iPod, udnytter Kindle en eksisterende infrastruktur, nemlig Amazons, og husk at iTunes Music Store ikke var i nærheden af at være klar da iPod blev introduceret, Amazon er klar, og har allerede 360,000 titler tilgængelige, og Amazons vision er rent faktisk at samtlige (skrevne) værker der er udgivet i menneskehedens historie, skal være tilgængelige på Kindle. Jeg synes dette er en smuk vision, som det undrer mig at man skal høre fra en privat, kommerciel virksomhed fra USA.

Unboxing
Det første jeg bemærkede, da jeg pakkede min Kindle ud, var at den viste nogle instruktioner på skærmen, jeg prøvede at fjerne den plastik jeg antog var placeret på skærmen, sådan plejer det jo at være, ude af stand til at finde plastikkens kanter, gik det op for mig at Kindle viste et billede på skærmen! eInk skærme er virkelig anderledes, sammenlignet med traditionelle computerskærme – når skærmbilledet først er dannet har det ikke brug for strøm, så selv om enheden var slukket viste den et billede.

Whispernet, trådløs adgang der bare virker!
Jeg var godt klar over at Kindle var en opkoblet dims (wireless device), så jeg var meget overrasket da jeg ikke var i stand til at finde en eneste reference til opsætning, det værende sig SIM-kort, WiFi eller lignende, i den korte dokumentation der følger med – underligt – hvordan kommer den så på nettet?

Så jeg var yderst overrasket da jeg, efter at have været en tur forbi MyKindle websitet på min computer for at ændre navnet og e-mail adressen for min Kindle, og efter en kort lur, opdagede at Kindle havde opdateret sig selv, og at der nu stod “Tölva” i stedet for “Kim Bach’s Kindle” på skærmen.

At se en opkoblet dims der bare virker så snart man har pakket den ud, burde ikke føles som en fantastisk ting, det er sådan teknologi burde virke, men vi er anderledes vant – knockout sejr til Kindle her!

24-November-2009 sendte Amazon i øvrigt en opdatering til version 2.3 af Kindle softwaren, og den virkede perfekt, og blev sendt automatisk – endnu et eksempel på hvordan teknologi burde virke – ingen iTunes og computer nødvendig – tak og lov!

Jeg er dybt imponeret over den aftale Amazon har fået med AT&T, der er nemlig tale om intet mindre end en gratis, global, mobil data-roaming aftale.

Passioneret fællesskab
Naturligvis skrev jeg om Kindle på twitter, og der gik ikke lang tid før jeg fik et svar. Det kom fordi jeg undrede mig over hvor jeg ville finde åbent og frit indhold – det andre kalder gratis – altså bøger der allerede findes på Internettet – f.eks. gennem Gutenberg projektet.

Disse bøger findes som regel i nogle standard formater der hedder .mobi, og dem kan Kindle læse direkte.

Svaret jeg fik på twitter, og jeg havde ikke formuleret et spørgsmål, bare luftet en undren, var at jeg skulle få fat i softwaren calibre. calibre og det er et must hvis du har en eBogs læser. Der er tale om et open source program som fungerer lidt som iTunes til eBogs læsere, det kan konvertere mellem mange formater, og sidst men ikke mindst, importere RSS feeds og overføre dem til Kindle og andre eBogs læsere.

Der er iøvrigt flere muligheder for at overføre data til Kindle, man kan enten gøre det via. Whispernet (e-mail), men det koster så $1/megabyte, så det er bedre at bruge det medfølgende USB kabel, som er standard mikro-USB.

PDF – ikke en eBogs standard
Mange er nysgerrige for at høre om Kindle understøtter PDF. Det korte svar er ja, det lange er noget mere kompliceret. De fleste PDFer er sat op til at blive udskrevet på A4 papir, og det passer ikke ret godt til Kindles 6″ skærm. Et af problemerne er at PDF er mange ting, skannede sider f.eks.

Dette skuffer sikkert mange, men problemet er altså PDF, ikke Kindle, man er simpelthen nød til at omformatere sin tekst så den understøtter variable “papir” størrelser, og der bliver nødvendigt at “teste” sine udgivelser på mange enheder.

En lidt sjov ting jeg har brugt PDF visning på Kindle til, er at jeg har lagt billetter på den, og brugte min Kindle som billet to gange under CPH:DOX – desværre havde de ikke stregkode skannere til nogle af arrangementerne, men jeg synes det ser sandsynligt ud at det ville fungere.

Amazon Kindle Store – impulskøbsalarm
Amazon Kindle Store virker som det skal, gå til forretningen, søg efter den titel du er intereseret i – her er det smart at Kindle har et tastatur, køb og titlen er klar på din startside i løbet af 30 sekunder – imponerende. Kindle bruger din Amazon konto, så hvis du har one-click slået til, så er din Kindle, effektivt, et kreditkort. Samtlige bøger kan i øvrigt hentes i en prøveudgave med adgang til udvalgt indhold, så man kan se om det er den rigtige titel, dette fungerer virkelig godt, men det er lidt for let bagefter at komme til at trykke køb, da det er standardknappen – derfor har jeg nu en kopi af “Pigen der legede med ilden” på engelsk. Det skal dog tilføjes at man straks får muligheden for at fortryde sit køb.

Der er også mulighed for at abonnere på en lang række aviser og tidsskrifter, jeg valgte straks International Herald Tribune og Asimovs Science Fiction. Det smarte, og farlige, ved aviser og tidsskrifter er at man får den 14-dage gratis.

Kindle som browser
Selv om Kindle umiddelbart er en “iPod for bøger”, altså har sin egen hukommelse hvor indkøbte bøger bliver downloadet til, så er Kindle også en computer der kører en speciel version af Linux. Der er også indbygget en browser, som tilgås gennem Kindles menupunkt “Experimental features” – her finder man “Basic Web”, og her får man adgang til en webbrowser, der, i den internationale version, ser ud til kun at give adgang til Wikipedia, men det er da heller ikke så tosset, gratis adgang til Wikipedia uanset hvor man er i verden.

Jeg har testet hvordan sider med f.eks. matematiske formler viser, og det ser virkelig godt ud.

Kindle er bestemt ikke verdens hurtigste browser, men det virker, og er gratis.

One Kindle Per Student (and Teacher)
En vision jeg får når jeg ser en dims som Kindle er at en dims som denne burde være tilgængelig for hvert eneste barn, eller rettere hver eneste “studerende” og lærere, og hvorfor nu det?

Kindle er enkel, virker robust, og kan allerede i dag, indeholde en kopi af alle de skolebøger man har brugt i hele sit aktive studieliv, det er lige fra Folkeskole til Universitetet.

Kindle eller Dynabook?Jeg synes at Kindle ser meget bekendt ud, og den minder mig om Alan Kays vision – Dynabook – Wikipedia, the free encyclopedia. “A Personal Computer For Children Of All Ages.”

Hvis samtlige børn (“studerende”) havde en platform som Kindle, ville det også skabe et nyt marked for skolebøger, hvilket burde være med til at forbedre kvaliteten – hvis man ellers tror på markedsøkonomi.

I dag bliver innovationen indenfor uddannelse bremset af ophavsretsloven, det er, f.eks., meget svært at hjælpe børn med ting som matematikopgaver over Internettet, fordi det ikke er muligt at dele skolebøgerne online, eller som downloads til en eBogs læser.

Lærer er i øvrigt i den brede definition, fordi vi alle vil blive, potientielle, lærere hvis denne teknologi blev gjort tilgængeligt for alle.

Rent faktisk er vi også alle studerende, nutidens samfund kræver af os at vi fortsætter med at uddanne os hele livet, er det ikke vidunderligt, og det er også sundt! Få din hjerne til at “pumpe jern”.

Hvor er verdens førende IT land?
HVORFOR kan jeg ikke få lov til at betale for min avis (og heller ikke BØLGEN ;-)) – der er nemlig ikke en eneste dansk avis der synes det var umagen værd at levere aviser gennem Amazon? Tilgengæld kan jeg, via. RSS og den uundværlige calibre software, hente Information, og det koster helt gratis.

At ingen danske forlag har fundet det nødvendigt at kunne distribuere via. Amazon var mere forventet.

Rygtet om litteraturens død er stærkt overdrevet
Kindle kombinerer vision og forretning, Amazon har leveret en dims der er så let at bruge som jeg mener det er muligt med nutidens teknologi, og der er en klar forretningsmodel. Amazon har en vinder her.

Hvordan går det så med at læse noget mere. Jeg er f.eks. nu halvvejs gennem min første bog, “The Raw Shark Texts”, som blev indkøbt til mig af min veninde @anetq fra den fine Undr! blog – tusinde tak for “gaven”.

Igen virkede twitter på mystisk vis. Da jeg roste bogen på twitter, og skrev forfatterens navn, gik der ikke mange minutter før jeg fik et “thanks” fra @steveha11 – forfatteren af the “Raw Shark Texts” – en bog jeg nyder meget. Det er fantastisk at forfatterne nu kun er et tweet væk. Så vidt jeg kan forstå, så arbejder Steve Hall på en filmatisering af “The Raw Shark Texts” – noget der ikke bliver helt let.

Jeg tror virkelig at Amazons vision kan få os til at læse mere, hvilket også vil få os til at skrive mere, så rygtet om litteraturens død (Information 2059: Amatørerne har gjort en ende på litteraturhistorien) er stærkt overdrevet. Hvordan det kommer til at gå med “bogen” – jeg tror personligt at bogen, som vi kender den, forsvinder, men at vores enheder vil blive så gode at vi slet ikke kan se forskel.

Her er et tip til hvordan Danmark kan blive nummer 1 på rigtig mange af de lister Statsminister Lars Løkke Rasmussen snakker om – sats på åben og fri digital distribution af alle skolebøger, og vi kan få en renaisance for læsningen og viden.

Bogen er død, længe leve bogen!

Forget this world and all its troubles and if possible its multitudinous Charlatans… – Celebrating women in tech

March the 24th 2009 is Ada Lovelace Day, the brainchild of Suw Charman-Anderson. Suw pledged to write a blog-post about a woman in tech that she admired, if at least 1,000 would make the same pledge, and since I’ve admired and been fascinated by Ada Lovelace since childhood, and especially after I read the wonderful book The Difference Engine, so I embraced the project, but at the same time I knew that it would be difficult for me to find just a woman in tech that I admire, that is because the list is long, and I’m happy to say that it’s actually getting longer.

In the end it turned out to be quite simple to name one single woman in “tech” that I admire, a woman that I’ve admired for 2,5 years since I met her at the wonderful BlogForum 2 – an initiative that we really need to revive – and almost did at Copenhagen Twitterfestival.

Since 2006 the woman I have in mind has become quite the celebrity, due to her uncompromising and relentless pursuit of the truth in the murky waters of the Danish tech-business, and this year she’s the natural selection, she’s the woman behind the mainstream breakthrough of the blog-media in Denmark, she is – of course – Bizzen/Toften: the journalist and blogger par excellence Dorte Toft.

Love/hate relationship with “tech”
I have a love/hate relationship with my field, the field known as “tech”. Tech is definitely one of the places where change is happening today, and I feel blessed that I’m involved in bringing this change.

But “Tech” is a field that is riddled by paradox. On one hand it’s crawling with greedy snake-oil salesmen, on the other it’s home to the most revolutionary, idealistic and altruistic people ever as well as some of the most wonderful concepts that humankind has ever come up with.

The problem with the snake-oil salesmen, is that, until now, they’ve pretty much got away with cheating their customers, the authorities, the business community and worst, their employees, and a lot of the snake-oil has been sold under the heading that Denmark is number one in tech.

It’s been a constant embarrassment to me, and I actually left the business four years ago, and it took me two years of “repenting” before I felt that could return to “tech”, and today I’m luckily to be employed by a tech-company that doesn’t carry any snake-oil.

Emperor’s new clothes
I’m just going to, briefly, mention the fact that Dorte Toft was the woman that noticed that Stein Bagger and IT Factory didn’t wear any clothes, thus exposing one of the biggest scams the Danish tech-sector has seen to date, but thank you Dorte for exposing these people, so that we can be protected against these predators and making it possible to feel proud about working in “tech” again.

Feminism isn’t “low-status”
What I’d rather celebrate today is that Dorte Toft is a self-proclaimed feminist, even though it’s – in her own words – a field that is “low-status”, and her labour of love “Nærmest Lykkelig I Nørdland” (“Almost happy in Geekland” – something got lost in translation sorry about that), where Dorte Toft has been writing and writing and writing about the benefits young women would have if the choose to join the so-called “though” fields, technology and science, a very noble cause.

I noticed that Dorte Toft also wrote a blog-post in observation of Ada Lovelace Day today. In this blog-post Dorte is pledging to return to “Nærmest Lykkelig I Nørdland”, I’m so, so happy to hear that, Dorte Toft has been toiling away, trying to ease young women into the fields of tech and science, and her work deserves so much more attention than the perpetual Stein Bagger saga.

To all the wonderful women that I’ve worked with, am working with and will work with in the future, thank you so, so much for putting up with us, we need you, and remember how far you’ve come.

When I mentioned to my father how much I loved having female managers, he simply said that he could never ever imagine have a female manager, I was appalled.

Women, “tech” is too important to be left to men
Women please don’t stop now, so that next time I’m in a position where I’m hiring tech-staff, I hope that I’ll receive applications from women. Looking at the number of students at the IT University in Copenhagen I’m quite optimistic that that would be the case.

DORTE TOFT: Please go work on “Nærmest Lykkelig I Nørdland”, I’m waiting for it, unlike the book about “Banditterne i habitterne” (“The Bandits In Suits”) – and remember feminism isn’t “low-status”!

YOUNG WOMEN: We really, really need you in the tech-sector. Tech is far too important to leave to us men, and listen to, and get inspired by Dorte Toft!

Celebrating the Enchantress of Numbers
I’ll close this post with these wonderful quotes.

We may see aptly that the Analytical Engine weaves algebraic patterns just as the Jacquard loom weaves flowers and leaves
Lady Ada Lovelace

Forget this world and all its troubles and if possible its multitudinous Charlatans – everything in short but the Enchantress of Numbers
Charles Babagge, inventor of the Analytical and Difference engines

Notes
If you want to learn more about the fascinating life of Ada Lovelace, daughter of Lord Byron, by many considered the inventor of programming languages, I’d strongly recommend “The Bride of Science: Romance, Reason, and Byron’s Daughter“, “Zeroes and Ones: Digital Women and the New Technoculture” and “The Difference Engine“.

I’m also building a “shrine” to Ada Lovelace on Algorim.dk, a result of “mellemrumssingulariteten” which was inspired by a young woman I know, this woman is, BTW., working in the purest field of them all 😉

Passion for industrial design: The spotlight turns to…Jonathan “Jony” Ive

Jony Ive - Apple Senior Vice President - Design

Yesterday, the 14th of October 2008, Apple had an event titled “The spotlight turns to notebooks”, where they unveiled a refresh of the MacBook Pro, a new version of the MacBook in aluminium and a new Cinema Display.

Clever spin
All of these announcements were already confirmed and leaked days before the event, Apple can’t or won’t, contain the leaks, and the new strategy seems to be to use the leaks to drive the hype.

Remembering how secretive Apple events used to be, I sort of, expected Steve Jobs to pull something out of the sleeves of his turtleneck, “one more thing”, but he didn’t, or did he?

One more “thing”
One notable thing about the event was that Steve shared the stage to such a high degree. This is a trend that has been going for some time, especially when it comes to events that focus on the Mac, it’s a bit like Steve isn’t that passionate about computers.

Luckily others are, and at this event Jonathan “Jony” Ive shined – and I’m not referring to the reflections from his shaved head.

It was simply a thrill to see this low-key, soft-spoken, man talk about the manufacturing process involved in producing the new MacBooks, the attention to detail, the months spend refining the new trackpad etc. etc.

Over the years, speculation as to who might take over the position as CEO of Apple after Steve Jobs, has been growing, and my first reaction was that I’d love to see Ive in that position, he’d be a natural.

But really that would be such a shame, so I’m convinced that Ive will stay in his current position, and there’s many more iconic designs hidden in that shiny bald head of his.

So watch the video where Ive talks us through the manufacturing process of the new MacBooks, it’s simply breathtaking.

Risky strategy?
The MacBooks themselves? To me they ooze quality. Apple has obviously decided that they will not address the current trend towards cheap notebooks, aka. netbooks, when asked Steve called it a “developing market”.

The strategy is risky, it defies the market, but I welcome it, and it will only mean that Apple will grow it’s market share in terms of revenue, instead of units moved. With these new notebooks, there’s no doubt that Apple owns the high-end market, and that’s where it’s the most fun, and profitable, to be.

The old MacBook product line has been plagued by quality problems, hopefully the new MacBooks addresses this, I’ll bet that this is the case, these are, to me, the first true Intel based notebooks, designed from the ground up for the Intel chips.

I’m tempted by Ive’s new industrial sculpture

The picture of Jonathan “Jony” Ive, that accompanies this article, is a frame from the video issued by Apple for the launch of the MacBook Aluminium, it’s Copyright Apple Inc. I hope that my use here is considered “Fair Use”.

Currently the video is available on the Apple Website here, it’s likely to be moved, and it’s a good guess that it’s already on YouTube. The video is produced much like a documentary, really professional marketing on Apple’s part.

One final thing: How do you like them Apples? – The spotlight turns to notebooks

Applenotebookevent - The spotlight turns to notebooksA draft of Steve Jobs’ presentation for the Notebook Event titled “The spotlight turns to notebooks” scheduled to take place on October 14th 2008 in Cupertino, has been leaked.

Since rumour has it that Apple is softening up to rumour sites: if you don’t like me publishing this rumour: SOSUME.

“Gi’ mig Danmark tilbage” by Natasja is blasting the Cupertino speakers!

Steve Jobs takes the stage

(applause)

Welcome, and thank you for coming.

One first thing:
Apple has realized that we can’t compete with Linux and has decided to make an investment in Linux. So we’re discontinuing Mac OS X in favour of Linux with KDE, all Mac OS X developers will instead be working on contributing to Linux, ending years of, mostly, passive and luke warm support for the open source movement. Apple wants to appologise for this mal-pratice, and all code will be shared back with the community.

The next version of Mac OS X will be renamed Linux Snow Leopard, and it will be licensed under the GPL – meaning that it can be freely copied, and installed, on any computer.

(oooooh)

Linux Snow Leopard is available as a free download from Apple AppStore, and it is available…NOW!

(applause and cheers)

The reason for this change is that captalism, as we knew it is dead, instead of competing to death and the focus on economic growth, that is destroying the planet, human kind will instead work to improve the quality of life for all.

Democratisation of technology will be instrumental in bringing these changes.

Apple wants to be part of this.

(Steve moves the cover on the table, pulls out a picture frame with a picture of Richard Stallman on one side and Nicholas Negroponte on the other side, from this frame he pulls out a beautiful sub-notebook)

So today I’m happy to announce the insanely great TuxBook, developed in coorporation with Asus.

Asus is bringing the change, and since our old notebooks really weren’t anything but repackaged Asus products anyway, we’ve decided that Jonathan Ive will now be working full time making Asuses look cool.

The TuxBook comes with 2GB RAM, 32GB SSD, WiFi, Bluetooth, a 3G modem and A-GPS. It sports 8 hours of batterylife, and can, optionally, be solarpowered.

Demo:
(The splash screen is a Penguin holding an Apple)

Isn’t that beautiful? KDE 4.1: BOOM!

The TuxBook will be priced at $99, and it is available…NOW!

Thank you all for coming, and Karl Marx was right.

(applause)

One more thing:
Since you can’t make money on stock, APPL will be unlisted from the stock exchange, Apple will in the future be a Section 501(c)(3) not-for-profit charity.

One final thing:
How do you like them Apples?

(standing ovations and wild cheers: T-U-X what’s that spell? TUX!, what’s that spell? TUX!)

Ba-Ba-Ba-BarCamp Copenhagen 8.2-Hum-A-Nah-Nah-Hum-A-Nah-Nah

Opdateret den 10-oktober-2008.

Vi har nu fundet stedet vi skal være. Det bliver på Københavns Teknisk Skole på Lygten 16, 2400 København NV. At vi har fundet sådan et fantastisk sted, betyder at vi udvider antallet af deltagere fra 50 til 100.

Så skal vi til det igen, for tredie gang i alt, og for anden gang i år, bliver der afholdt BarCamp Copenhagen (applause).

Det eneste der er helt klart på nuværende tidspunkt er at dDet kommer til at foregå i på Københavns Tekniske Skole, Lygten 16, 2400 København NV (doh!), og at det bliver lørdag den 22-november-2008 fra kl. 10:00 til ??.

Hvis du ser videoen nedenfor så lover vi i øvrigt at “blyanterne vil vende tilbage”, hvis vi ikke finder nogle sponsorer. Vi vil gerne holde BarCamp gratis, men også på et vist niveau, så hvis vi ikke finder sponsorer, så må vi skrue ned for ambitionsniveauet, og i januar var vores prop altså nogle blyanter – fine, jo vist – men vi vil så gerne give jer noget endnu bedre.

Reglerne kender i vist efterhånden, ellers kan i læse dem her.

BarCamp handler om deltagelse, så det der gør BarCamp interessant, er DIG. Vær parat til at dele!

Til de første to BarCamp Copenhagen handlede det mest om præsentationer, men i år håber vi at kunne få mere gang i nogle diskussioner, og måske vil vi forsøge os med et mere workshop eller open space lignende format, smid evt. en kommentar hvis du har nogle ideer!

Vi regner med at have plads til 50 100 mennesker deltagere, og vi har allerede nu 31 tilmeldinger.

Så skynd dig at melde dig til ved at redigere wiki-siden på BarCamp.org, eller ved at bruge vores Facebook gruppe.

Ses vi? Det tror jeg nok vi gør!

Æbletræet.dk fylder 2 år – stort til-held-og-lykke og Elvis har forladt bygningen

Elvis Smoking - By Esben ThomsenI går, den 3die April, kunne Æbletræet.dk fejre sin 2 års fødselsdag. Æbletræet.dk er et Internetbaseret, indholdsdrevet, fællesskabs projekt der startede som en idé om at skabe en begynderguide til Mac, men er endt med at være en af de, ja måske det, største Danske online fællesskabsdrevne indholdsdrevne Internet projekter. Projektet er dog, for længst, gået skridtet videre, og indeholder nu artikler om meget andet end Apple.

Historien om Æbletræet, eller MacWiki som det oprindelig hed, er dokumenteret på Wikien, hvilket er ganske unikt, som du kan finde på http://www.theappletree.dk (jeg bruger – bevidst – den Engelske version – da projektet – naturligvis – som nogle af de første – benytter en IDN (International Domain Name) – nogle skulle jo starte, og det blev os.

Ideen til Æbletræet udsprang af det danske forum for Apple fans, Macnyt.dk, en gruppe af faste brugere var blevet trætte af at besvare de samme spørgsmål om og om igen, så det blev diskuteret om man kunne skrive en bog eller lignende.

Fra start af var det klart, for mig, at man absolut ikke skulle skrive en bog, men lave det online på Internettet, og jeg havde noget i baghånden, MediaWiki, det samme system som driver Wikipedia – der er åben og fri software.

Første møde blev afholdt den 3-April-2006, og da jeg kom hjem installerede jeg MediaWiki på min server og oprettede de første artikler.

Der gik noget tid inden de andre projekt deltagere forstod ideen, og indlæringskurven for MediaWiki er ikke just lav, derfor opsatte jeg også et traditionelt forum, som stadig kan findes på http://macwiki.kimbach.org/portal, og diskussionen flød.

Det er fantastisk at arbejde sammen om at producere indhold, og når man kan se at der er mange rettelser på MediaWikis recent changes, så virker det simpelthen ganske inspirerende, og man får lyst til at skrive mere.

Jeg føler det er nødvendigt at aflive nogle myter, da den slags opstår når folk ikke taler sammen.

  • Jeg har ingen ambitioner om at være leder eller bestemme noget som helst
  • Jeg er blevet beskyldt for at tage Æbletræet som gidsel – det kan jeg ikke se – grunden til at vi ikke er på PHP5 – som jeg helt ærligt – ikke forstår er så vigtigt – er at vores udbyder Site5 ikke understøtter det, og da projektet er baseret på gratis og frivillig arbejdskraft, så har det været svært at få ejeren af serveren til at bruge tid til at få flyttet server

Og så et par ord om hvordan jeg fungerer: jeg bliver stresset af at tænke på produktions-problemer, og i påsken forsøgte jeg at opgradere Æbletræet.dk, det gik ikke helt som ventet, jeg bad derfor om, først at få os på PHP5, derefter ville jeg installere MediaWiki 1.12, og så flytte til Gigahost (hvilket jeg ikke tror er så god en idé), hvis man spørger kan man jo få svar, og jeg venter på min frivillige hjælper.

Fundamentalt hader jeg simpelthen drift, og her mener jeg ikke den første installation, men de problemer der – næsten altid – opstår når man skal opgradere serveren – så vidt jeg husker – så har vi nu ikke haft de store produktions problemer – en enkelt gang var vi nede i 48 timer – fordi Site5 havde skiftet IP adresser.

En grundregel – som gælder al drift – er: “if it ain’t (totally) broke – don’t fix it” – på Dansk: “pil ikke ved noget der fungerer, også selv om det ikke fungere helt optimalt”. At dette så betyder at “change” ikke sker, er uheldigt, men det er simpelthen ikke noget man kan byde frivillig arbejdskraft – så ting tager tid!

Jeg har – længe – forsøgt at få vores server opgraderet til PHP5, men igen – frivillig arbejdskraft skal man ikke presse – man må væbne sig med tålmodighed. Tro mig, jeg ved det – for 3 år siden prøvede jeg at køre et del-projekt i min Frivilliggruppe hårdt, det faldt ikke i god jord – og folk hadede det jeg producerede, men jeg producerede! Siden dengang har jeg væbnet mig med tålmodighed.

Efter 2 år kan projektet dog, sagtens, stå på egne ben, og jeg føler at min fortsatte deltagelse i projektet ville betyde en fragmentering af fællesskabet, der – efter min mening – ganske enkelt ikke brug for endnu et Dansk Apple site, og nøj hvor er det imponerende med de nye Apple fora, som i kan se havde vi et Drupal baseret forum allerede for 2 år siden.

Jeg vil derfor, fremover, ikke deltage i projektet som andet end bidragyder, med mindre jeg bliver udelukket – hvilket jo ikke kan udelukkes (pun intended).

Faktisk er det eneste jeg er ked af, at jeg har mistet en fantastisk god ven – det bedste minde jeg har er dengang vi bagte en kage til brug for Dansk Flygtningehjælps 1000 flere arrangement, og jeg undskylder MANGE MANGE gange for Beyoncé, som blev Skypet til dine sarte ører mangen sen nat.

Det sjoveste er faktisk at vi, mest fordi vi havde en åben proces, blev udsat for en domænehaj. macwiki.dk blev registreret af en af den slags personer ,der ikke burde have lov at betræde Internettet, sjovt nok blev navnet jo æbletræet.dk, så fjolset brændte inde med domænet LOL.

God vind kære Æbletræ, det har været fantastisk sjovt! Specielt tak til David, Esben men også Thomas x 2, Wendelboe, Sebastian, Allan, Liv for at have holdt mig ud så længe, noget af en bedrift ;-).

Et par fakta – Æbletræet.dk kører videre, så længe det ønskes. Hvis der er interesse i at bevare navnet, hvilket jeg da tvivler på, så kan det redelegeres, jeg ejer det p.t. I øvrigt sletter jeg aldrig indhold, men da vi ved at dublikeret indhold er noget Google ikke bryder sig om, trækker jeg stikket så snart der er flertal for det.

Jeg er blevet beskyldt for gidseltagning – intet er mig fjernere – jeg er SUPER stolt af at have været med til dette – og det var det jeg kunne få jer med til. Fremtiden tilhører egen-produceret indhold, som man selv hoster og ejer, websitet er dødt! Elvis har forladt bygningen.

Billedet der ledsager denne artikel er en manipulation udført af Esben Thomsen, det er Copyright Esben Thomsen, men jeg håber at dette falder under fair use. Esben kender mig bedre end de fleste, og det “grønne skrig” opsumerer “mig” ganske godt (man kunne sige perfekt)

Papirbesparelse…

Q:
Har du forslag til besparelser indenfor print/ kopiering (sort-hvid/farve tryk) og/eller papir-forbrug, – (også gerne systemændringsforslag), så skriv dit forslag og send det til postkassen: xxxxxxxx

A:
Det gælder jo ikke kun om at begrænse medarbejdernes papirforbrug, men også den mængde papir der sendes til kunder i form af regninger, og her er der også en stor logistisk omkostning da brevene jo skal bringes ud.

Det skal også nævnes at man udover at benytte dobbeltsidet tryk, også kan udskrive flere ark på samme side, og personligt er det meget få af de dokumenter jeg udskriver på den måde, der bliver sværere at læse.

Ellers er det også relevant at vælge en papir-leverandør der prioriterer miljømæssig bæredygtighed højt, og det er ikke kun for at opnå en økonomisk besparelse på “papiret” (bevidst vittig ;-), det må nemlig gerne koste mere, hvis det samtidig er bæredygtigt, og så er det et godt signal at sende til omverden. Noget andet er at hvis prisen er højere, kan det også virke som et inictament til at sænke forbruget yderligere.

Bortset fra det kan man rent faktisk ofte undgå helt at udskrive, det kræver bare at man lettere kan finde informationerne, og så er det vigtigt at man ikke længere sender f.eks. Word dokumenter til hinanden, men i stedet henvisninger til Intranettet/Lokalnettet, så man vendes til at læse informationer på skærmen i stedet for at udskrive den.

Systemer til vidensdeling som wikier, diskussionsfora og team blogs kan også hjælpe til at begrænse mængden af papir, der er heller ikke længere diskussion om hvilke versioner af et dokument man har. Man kan også med den slags systemer begrænse behovet for møder da projekter lettere kan diskuteres og resultater fastholdes når man bruger den slags systemer.

Det kunne også være en idé hvis der var en computer i mødelokalerne der var koblet op til lokalnettet og en storskærm, som man var SIKKER på virkede – det er min opfattelse at der bruges en del tid på at være sikker på at et mødelokale har fungerende netforbindelse etc. På denne computer vil man så kunne hente projekt dokumenter, inklusive diskussioner, så de kan diskuteres på mødet.

Principielt kan det diskuteres om det overhovedet er nøvendigt at have en harddisk i en computer, afskaffelsen af den lokale harddisk vil betyde at man altid vil gemme informationer på en sådan måde at man kan få fat i dem fra en vilkårlig computer, og derfor ikke har behov for at udskrive dokumenterne når man går på besøg hos kolleger for at diskutere dokumenterne.

Dette vil dog stille større krav til netværket, og derfor vil det være en idé at tænke i en distribueret infrastruktur, f.eks. ville det være smart hvis en udviklingsafdeling havde sin egen filserver på lokalnettet, der så blev replikeret til firmaserverne automatisk.

Konkurrencemailen er i øvrigt et “sjovt” eksempel på forkert brug af elektronisk distribution, da der er en vedhæftet fil medsendt, i stedet for et link til Intranettet.

The Pod Bay Doors have been opened – Godspeed Arthur and thank you

HAL Sheeding a tear for Arthur C. ClarkeThis week, the world got a lot less interesting, when the visionary, humanist, inventor and author Arthur C. Clarke died. I really considered not commenting on it, because others would be better at it, and the picture from Joy of Tech on the left sums up my feelings.

Remembering a great visionary and humanitarian

Arthur might not be the best writer, but his clear visions, belief in humanity and always good spirit was such an inspiration.

Clarke has mostly been remembered for his two most famous contributions to the collective heritage of humankind:

  1. The movie 2001
  2. The concept of Geo-synchronous communications satellites

The only thing that I feel sorry for, is that Arthur didn’t live to witness the discovery of Extraterrestial Intelligence, which I’m sure is on the verge of happening, and when we have First Contact, I hope that the politicians and scientists read the works of Arthur C. Clarke, before trying to understand E.T., I really feel that Arthur did.

First Contact

I’ll give you an example, and it’s my favourite part from one of his books, “The Fountains of Paradise”.

As is traditional with the novells by Arthur C. Clarke, the plot contains several independent sub-plots, and that is the strongest aspect of his writing, it never gets dull, and it’s filled with humour, and insights into humanity.

The main plot in the “Fountains of Paradise” is really about the construction of an elevator to the Clarke Belt, the geo-synchronous orbit, 36,000 kms from Earth.

But the by-line is a story about First Contact – e.g. the discovery of intelligent Extraterrestrials – a favourite topic of Clarke – it’s also about Artificial Intelligence – the favourite topic of Clarke.

The sub-plot is similar to “Rendezvous with Rama”: Due to universal limits of relativity, you can only travel at sub-light speeds. Another universal law is that the ordinary life-spans are too short even for ET, so ET is investigating the universe using unmanned probes.

Earth, or rather the solar system, is visited by such a a spaceship, and onboard is a computer or more correctly an AI – that is somewhat secretive – but co-operative – and we have so much to learn, like the fact that we’re an emerging level 1 Civilisation, at least in the 22nd Century, where the book is taking place.

Clarke suggested that advanced Civilisations goes through three levels:

  1. Civilisation can control energy on Planetary level
  2. Civilisation can control energy on Solar level
  3. Civilisation can control energy on Galactical level

Needless to say we’re not even a level 0 civiisation right now. When ET finally arrives, some hundred years after the probe visited, he expresses admiration for the achievements of “such a young civilisation.

Well the computer abroad the space-probe, is co-operating and teaching us lot’s of things, without violating the rules about giving away information posessed by a higher level civilisation, so we’re only given hints, like a level 1 civilisation, has mastered the conversion of matter to energy and back – e.g. has things like matter transporters and replicators, like in Star Trek.

That is until someone at a Theological Institute decides to transmit the complete religious scriptures to the computer, it painstakingly analyses it, points out the fundamental flaws of religious thinking, shuts down communication with a comment that expresses disappointment at such tribal manners from an emerging level 1 Culture, and sorry but now you have to switch to direct communications, going to cruise mode, shutting down, bye.

Mind you, ET is 50 light-years away, so everyone was upset by the actions of the religious people, but really it was also the end of religious thought, and humanity could move on the bigger projects, like building the space elevator.

The concept of the Space Elevator was lifted from a Russian scientist Konstantin Tsiolkovsky, that Arthur credits in the closing notes of “Fountains”. Clarke also suggests that it might be possible to build it already in this century, and the concept is well thought out, and actually feasible with current technology, unfortunately the current funding of space exploration, dictates direct military benefits, and the military seems to love chemical rockets, what a shame.

Other contributions

Another important contribution by Clarke, was his 80th birthday special feature, where Discovery dedicated an entire evening to Arthur, another was his series The “Arthur C. Clarke’s Mysterious World”, where he was also dealt with myths and Urban legends, paving the way for the “Mythbusters”.

Clarke deserved the Nobel Peace Price, not least for deciding to live his final many years in war-torn Sri Lanka.

The Pod Bay doors have been opened, Godspeed Arthur

The Imperial Cinema in Copenhagen is showing “2001: A Space Odyssey” on Monday 24th of March oops April 28th at 3.45pm CEST.

Imperial has one of the best cinemas in Northern Europe, expect me to be in the audience, I can’t really think of a better way to pay tribute to Arthur, get your ticket here (link will probably expire soon ;-)).

I’m humbled by your creative vision: The Pod Bay doors have been opened, and my God it’s full of Stars. Godspeed Arthur!

The picture that accompanies this article is from the great comic strip, The Joy of Tech. I dare to claim “fair use”, and why don’t you click here to buy some merchandise, or one of the paintings – I’d love to own “HAL 9000 shedding a tear” as a painting. BTW: I’m not making any money from providing Joy of Tech with such a link, welcome to the future of advertising ;-).

BarCampCopenhagen: Party for your right to geek

BarCampCopenhagen LogoAs it might have caught your attention, the second BarCampCopenhagen took place this Friday (25th of January 2008), and there was great energy in the building. It’s evident that there’s a strong interest in having an event like BarCamp in Copenhagen, and it was inspiring, just to try to tap into that energy.

On the practical level, BarCamp was a great success, especially thanks to generousity of Beaconware (Troels, Allan and Kimmy) and of course Toothless Tiger (Henriette and Thomas) and Laura who moderated the “Kangaroo?” sessions, and thanks to the sponsorship from BridgeIT (my employeer), the event could be taken to such a high level, without having to charge the participants.

I must say that I’m amazed by the group of dedicated and interesting people that showed up, this is what they do for a living, but they’re also interested in sharing their ideas openly – thank you all!

To me the greatest moments were that I, finally, got to meet some people, that I’ve been following online, in real life.

If you have to criticise the event a little, I think we had some “growing pains” – in 2006 the event was more intimate, since we could all fit around one table, this meant that we could have more of an “open space” type of event, and that is the format that I prefer.

Civilisation 0.1

I did a presentation – Civilisation 0.1 – a pun on Tor Nørretranders Civilsation 2.0 – and I had some (understatement) difficulty making my points, that most likely had something to do with the fact that I had the wrong audience, since they’re all “believers”. Knowing the audience is, I believe, number one on the list of things to remember when doing a presentation of any kind, so that was sobering.

Since I failed to get my points across, talking about Pyramids, Archs and Fountains, I’ll try to do better here.

My presentation was inspired by this famous quote from Alan Kay:

If you look at software today, through the lens of the history of engineering, it’s certainly engineering of a sort—but it’s the kind of engineering that people without the concept of the arch did. Most software today is very much like an Egyptian pyramid with millions of bricks piled on top of each other, with no structural integrity, but just done by brute force and thousands of slaves.

My argument is that we’ve, so far, been building pyramids, but that we’ve invented the arch.

“The Pyramid”, is current ICT businesses, and their monopolistic pratices
“The Arch”, is “open source” and MM(O)C (Massively, Multiuser (Online) Collaboration)
“The Aqueducts” is the “Internet”
“The fountains” and “Temples” are the “things” we can build using “the arch” and the tremendously powerful tools and technologies we have in our hands.

I also tried to make these points:

  • Basic infrastructure should be free
  • We’re busy building “Pyramids” – using brute force
  • Civilisation is still in beta
  • We actually have the power to change things – get involved
  • The beer isn’t free – it will cost money
  • Join the revolution

Like I said, and this was obvious if you attended, I wasn’t too good at getting these points through, and to me, one of the main ideas of BarCamp, is to throw ideas on the table, even half baked ones, and have them tested, and even shot down.

My ideas was mostly shot down, and I got a “Emperor’s new clothes” type of comment: “To build the aquaeducts that feeds the fountains you already need an arch”, and someone else pointed out, that “something” was missing going from “The Pyramid” to “The Arch”, did it just appear out of the blue? I didn’t really answer that too well, my point is that the technological equivalent of “The Arch” has been/is being invented, now we can go build the aquaeducts and fountains armed with that knowledge.

Christian Schade was the most sceptical, I need people like him to question my ideas, so thank you Christian.

I’ve actually done a lot of thinking about this, basically I’m a strong believer in utopian ideas – they’ re getting a bit old, and others are better at getting them across than me.

I enjoyed the discussion we had afterwards, and I think that I managed to sell some of my ideas. It’s really quite simple, don’t wait for the revolution to happen, get involved. Like I said, this was the wrong audience, since they’re all already involved in the revolution.

My presentation did align itself, almost perfectly, with the two that followed, those of Christian Schade and Tania Ellis.

The Digital Divide

I was very pleased to, finally, meet Christian Schade, a person that I’ve been following for some time. I’ve never met him before, and I only knew him because he, sometime ago, added me as a contact on the online service Jaiku. The way he’s using a microblogging service is very similar to the way I use it, he often posts short messages that only he can understand – like a song that he had some sort of association to.

Christian talked about “the digital divide”, and he started out by stating that the difference between the things he was going to talk about, and the things I talked about, was similar to “the glass is half-full” (me)/”the glass is half empty” (Christian). You could say that I’m the optimist and Christian is the realist.

Christian got his points through, and they’re quite sobering. It’s possible that the younger generation is tech-savy, but they’re basically IT illiterate, yes they know how to use their cellphone, but the Nokia N95 they’re carrying around really is an extremely powerful computer, that they’re just using to TEXT each other.

Since the current trend is that businesses, and the public, use more and more advanced electronic solutions – yes: e-mail qualifies as advanced – IT skills are increasingly important, skills that the educational system isn’t focusing on.

So the digital divide is getting bigger, even in developed countries, and no one seems to care, like Christian pointed out, no one has really seriously looked at the problem with the digital divide, since the Dybkjær report, and when that was issued, they weren’t even sure if the Internet should be the backbone of the “Digital Denmark”.

Of course part of the problem with technology has to do with accessibility, and the general computer really is too complicated to be the basic tool of the digital revolution – no-one should have to know what a firewall and an anti-virus program is…We have a great challenge ahead of us, but no-one seems to care.

I later had a long discussion with Christian, and that was great.

Capitalism with a human face

Tania Ellis at BarCampCopenhagenBarCamp was also graced by Tania Ellis, author of the book “De nye pionerer” (The New Pioneers), and her presentation was about “Social business” – new alliances (oops ;-)) between economics and humanism.

Tania started out by showing a picture of the two choices of careers you’ve had since the 70ies, either you’re the poor, “peace and love” hippie or the greedy business man, but could a third way be emerging? A way where you can merge and/or mix the two, achieving balance and the best of two worlds.

Tania has been giving this a lot of thought, and the examples she found were ranging from the relatively well known (Life Straw), to the “interesting” (Solar Powered Vibrators) to the self-contradictory (Environmentally friendly munitions).

After Christian’s venture into dystopia, Tania presented hope for the future, maybe that is an attribute of the feminine? Afterwards she said that having children certainly helps, something that Christian tried to protest ;-).

I think that Tania managed to put words to my ideas, and present them is a structured manner – the “exercise” of writing a book is probably helpful ;-). Seen as a whole, the pre-dinner presentations by Christian, Tania and me fit extremely well together.

BTW, the splash screen on Tania’s web-site is a quote from Alan Kay. It used to be part of the name of my PowerBook, until I discovered that iTunes Music Store doesn’t like long computer-names, strangely enough the fact that I’ve written about the solution, is the biggest driver of traffic to my blog!

del.icio.us

After these three Kangaroo? tracks, it was time for dinner, and that was just del.icio.us (sorry or soz as I’ve begun to say recently).

Ruby don’t take your love to town

After the break, I decided to stay truer to my Geek roots, and attended the session “Ruby, Rails <meta>?” by Casper Fabricius. This was a great introduction to Ruby. Ruby is definitely very cool – like Neo cool – and I do love interpreted languages. I got a flash-back to the strangest language I’ve ever worked with, APL – an interpreted language that I have mainly used on an IBM mainframe.

One thing I find interesting is the trench-digging, and categorisation of people based on what programming languages they use – with the possible exception of Perl, I haven’t seen a programming language I couldn’t master with relative ease, and I’m, of the conviction that you need to have some general awareness of the different languages and tools that you have at your disposal. If Ruby can get the job done, quicker and faster, you should be allowed to use it.

Unfortunately Denmark is Microsoft country extraordinaire, and .NET is way too dominant. I totally agree with Casper that Reflection in C# is very hard to grasp, within this field Ruby is pure simplicity, and it is just beautiful.

As with all interpreted languages, there are justified performance fears, but if you can deliver solutions quicker, the benefits might overshadow those concerns.

Casper asked the question: so what can you use all this Neo-coolness for? He didn’t really have the time to answer this, but Ruby is being used to build world-class applications.

If you want to get started with Ruby, Casper pitched the web-based Ruby development environment Heroku, and it looks like a good place to start venturing into Ruby coolness. Heroku is in closed beta, but you might be allowed to pass through the Pearly Gates to Ruby coolness, by contacting Casper. [Casper has made me aware (see comments) that Heroku is for Ruby on Rails development, it’s important to distinguish between the two].

Quo-vadis?

The most surprising presentation of the evening, was the presentation by Henrik Biering of the work NETAMIA has done to develop a single-sign-on (SSO) engine, called net-safe. Net-safe is a standards based, plug-able SSO infrastructure, that also contains address validation etc. Running a successful on-line business depends on correct identification of the users, and having valid user data, also means that the users are better behaved.

Henrik knew what he was talking about, based on the experiences of the huge user base of heste-nettet.dk, which he runs. I guess it is obvious, but it really was an eye-opener to me, correct/valid information of users is extremely important, if you want to run a serious web-site.

Everyone in the room was blown away by seeing how polished a product Net-safe is, and when asked how much it had cost to develop it, Henrik answered: hmm, it was something I did together with my son…Amazing!

Embracing the chaos

Henriette talked about how to get businesses to embrace the chaos of the net, it’s a topic she’s writing a book about, and I look very much forward to it.

Engaging the geek warp drive

After all these sessions, I really needed a break, but when Michael Widerkrantz aka. MC, started rearranging the chairs, I just knew that I had to attend.

MC talked about IPv6, and why it’s important. In case you don’t know, IP is the basic communications protocol of the Internet, and the version we’re currently using, has a build-in limit of the number of allowed network addresses, that we’re about to hit, MC said that a recent session of RIPE, estimated that it would happen in less than two years.

I know just a little about networks, but this was mostly over my head, basically I’m sitting somewhere above layer 7, and just want the network to, ahem work, so it beats me why the ISPs just don’t get started rebuilding the infrastructure for IPv6, before it’s too late.

An interesting side-note is that a friend of mine just recently returned from South Africa, and I found out, because her computer acted strangely, that it was because she had been using IPv6 – as seems to be common with developing countries, South Africa is skipping the legacy infrastructure completely, a legacy that will soon hit us, and the entire digital economy, which today is synonymous with the economy.

Thank you

That concluded the official program of BarCamp Copenhagen, and what a great night it was, the air was literally buzzing with energy. Events like this are important, and I hope that this will get people talking and taking similar initiatives.

Weaving an untangled web – The Friend of a Friend (FOAF) project

FOAF Project LogoThe Friend of a Friend (FOAF) project

I really need to “get out more”, since I’ve only just now discovered the Friend of a Friend project (FOAF), and I LOVE it!

The Friend of a Friend (FOAF) project is creating a Web of machine-readable pages describing people, the links between them and the things they create and do.

Say what?

FOAF is an important part of the so-called semantic-web, and FOAF is just a so-called RDF specification of who you are. RDF (Resource Description Framework) is one of the basic technologies of the semantic web, and it’s nothing more (or should I say less) than an XML schema condoned by the W3C for describing resources.

Think of RDF as “the mother of all links”, RSS and Atom actually uses RDF.

The problem with links

So what is that RDF does better than the tradtional link?

When you create a link, you rarely remember to provide important information about what it is that you actually link to. At best you provide an ALT attribute (description) to an image tag. Google actively uses the ALT tag when indexing images, but if the link to an image contained more information, eg. semantics, Google could do a much better job.

Semantics means that you provide information about content and context, not just a link to it. You could call that metadata, abstracts or just “data”.

Many CMSes uses the URI of posts to provide some semantics, it’s often called SEO (search engine optimisation), the URI of this post has FOAF in it, meaning that a link to this article indeed contains some semantics.

A common standard for the WordPress CMS is that it uses year, month, day and the title of the post to generate the URI.

The problem is that this information should be provided in a structured, machine readable and – most importantly – open format, in order to make it possible to provide semantics.

I actually despise the concept of SEO, since it amounts to cheating, the only valid SEO is:
“provide interesting content”

A semantic “you”

A number of standards for providing semantics exists, one of the most interesting, especially in this day and age of social media, is the FOAF format.

FOAF is a format that describes you and your connections to provide semantics about people (you) and your connections (friends), in a standardised way, using RDF.

The FOAF file contains information about who you are, how to contact you, but most interestingly it contains links to your friends, and their FOAF files.

The beauty of FOAF is, that all you have to do, is:

  1. Create a FOAF file, for instance using FOAF-a-matic
  2. Put it on a server
  3. Provide the URI
  4. Make sure that it can be found by others (e.g. by posting a link on a page you know is indexed)

Chances are that the FOAF spiders will have a feast on your FOAF, sooner rather than later.

Create your FOAF file

It’s quite simple to create a FOAF file, all you need to do is go to FOAF-a-matic, fill in a number of fields, generate the FOAF file, copy it to a text-editor, publish it on your web-site.

Below is a screenshot of the FOAF-a-matic page.

FOAF-a-matic screenshot

Take back your profile, it’s…YOURS!

No need to register with social networking sites, your profile is YOURS.

Who owns the information about “who you are”? You do! Should that information be made available in an open format? You bet! RDF and FOAF is the way to go.

And don’t take my word for it, just take a look at the people who are promoting and developing RDF and FOAF…

So how did the chicken cross the road

I’ll provide you with the story about how I found FOAF, since it’s interesting to say the least.

My good buddy Sebastian Lund just recently set up his blog, Silence is deafening, and I’m looking forward to following it, he’s using a beautiful theme, the Dilectio Theme, developed by Design Disease.

Design Disease has a number of free WordPress themes available, and you can test them, when I tried that, their “Lorem Ipsum” turned out to be an article by no other that TBL, timbl, Tim Berners-Lee, Mr. Web himself, and he was writing about blogging and FOAF…

So:

What an untangled web we’re weawing.

Now I need to think of a good URI for my FOAF file, TBL suggests this:

A lot of people have published data about themselves without using a URI for themselves. This means I can’t refer to them in other data. So please take a minute to give yourself a URI. If you have a FOAF page, you may just have to add rdf:about=”” and voila you have a URI http://example.com/Alan/foaf.rdf#ABC. (I suggest you use your initials for the last bit). Check it works in the Tabulator.

Ready, steady FOAF

So what are you waiting for? Create your own FOAF file, and start sharing.

And now I’m moving on to explore Tabulator, more on that later…
