The Return of JavaSript

A few days ago a friend of mine was telling me he doesn’t get the reason for all the hype about JavaScript that has been in place recently. Even though I always considered JavaScript one of my favorite programming languages, I obviously acknowledged that it had lost some popularity after its original usage boom. And I had no ready answer to give him other than speculating about a possible fad cycle theory (many people talking about it after the first DHTML stuff, then most letting go of it simply cause they haven’t fully understood it — until someone came up with Ajax, and all the fuss was back, etc). But today I was reading an article that a contact of mine shared via Google Reader, and I think I might have found at least part of the answer:

“It will be interesting to see how Microsoft will improve IE for its cloud computing platform Windows Azure, when Firefox, Safari and Chrome already offer the technology to run JavaScript-heavy cloud services effectively.”
(…)
“The real problem with IE8 is that it completely missed the boat on the most important trend in browser development these days – JavaScript acceleration.”

A (im)perfeição digital

Cada vez mais me desiludo com as pequenas imperfeições que encontro nas linguagens de programação e códigos/programas informáticos deles subsequentes. Nem o C me parece mais ser tão simples e perfeito… Erros no html vão além das implementações míseras de alguns browsers, atingindo a própria definição do “sagrado” W3C…

Isso tudo faz-me pensar, caso algum dia os computadores, dotados de inteligência artificial, venham a criar por si mesmos versões optimizadas e mais evoluídas deles próprios, se eles acabarão por transmitir aqueles pequenos erros de design, os bugs que escaparam no momento da sua criação…

Talvez nós humanos tenhamos passado o vírus da imperfeição aos computadores. Quem sabe, ao criá-los demos-lhes não o sopro da vida, mas o espirro da vida!

The Philosophy of Colored Scrollbars

Some thoughtful opinions expressed at a DynamicDrive forum post about custom colored scrollbars using css:

rohis: I’ve heard a lot more people cumpliment how nice a website looks with a colored scroll bar than how violated they feel that their scroll bar on one specific page isn’t gray.

Twey: Yes, but it can be unpleasant: if the user is colour-blind, for example, and uses a high-contrast chrome theme, then can’t see the scrollbars, it would reflect badly on your site.

wiklendt: Goodness. If the colour blind person can’t see the scroll bar after the web designer changed it to match the colours in the website, what’s the chance they’ll see the website itself? By reason, then, wouldn’t they see nothing at all, let alone the scroll bar?

Not to mention there is a varied degree of intensity with colour blindness. some see a spectrum change, others don’t see certain colours at either end of the spectrum, some flat out don’t see certain colours in the middle of their spectrum itself.

A web designer can’t possibly cater for all these possibilities.

Am I to understand, me twey that you are so proficient and purist in your code that you cater for the blind? There is code, you know, that certain programs turn the data into speech for the sight impaired. Also, there are people who still use IE2, NS2, or 16 color monitors, or 480 x 320 pixel screen resolutions - should us designers make all of our websites black and white default non framed non flashed non coloured non css’d non interesting just so that all people in the world can view it?

besides, it’s not just the one scroll bar that’s effected in the change of colours, it can sometimes be right inside the site if the designer has chosen to use frames for that site (inline or otherwise). to have a nice lilac and purple colour scheme throughout only to be interrupted by an ugly default coloured scroll bar is almost an insult.

Emphasis mine.

Piratas!…

Há uns dias atrás, um amigo meu lamentou o encerramento do site tv-links.co.uk, que hospedava dezenas de links para filmes e séries de televisão que se podiam ver online. Eu já tinha sido encaminhado para esse site várias vezes no passado, mas felizmente consegui resistir a tornar-me um utilizador frequente, já que eu me vicio muito facilmente em séries. De qualquer modo, continuando: naquele dia eu não liguei muito ao que o meu amigo me disse, apenas ri-me do que eu considerei mais uma das peripécias da internet.
Contudo, hoje acidentalmente fui parar ao artigo da Wikipédia sobre o site, e mal acreditei no que eu lia, ao descobrir que o criador do site tinha sido preso e o site encerrado, quando o disclaimer do site dizia claramente:

TV Links is not responsible for any content linked to or referred to from these pages.

TV Links does not host any content on our servers.

All video links point to content hosted on third party webites. Users who upload to these websites agree not to upload illegal content when creating their user accounts. TV Links does not accept responsibility for content hosted on third party websites.

Ainda assim, o site foi encerrado pelo FACT, em conjunto com a polícia local do Reino Unido, com acusações de “facilitação de violação de copyright na Internet”!

É absurdo! Aliás, um post anónimo inteligentemente questiona o acto, nos comentários ao artigo sobre o assunto no Slashdot:

“(…) here is a site, leveraging user content to provide the MPAA and such with direct links to content that is in violation. This seems like the perfect way to quickly and easily send massive amounts of DMCA takedown notices and such. (…) They might have just killed something they could have used as a great tool.”

Ravenspear no entanto esclarece logo a seguir:

“Most of the actual content was hosted on foreign servers in asia/europe, so a DMCA takedown notice would have done diddly squat to remove it.”

Mas como bem diz Jack Schofield, “se colocar links é ilegal, quantos de nós somos culpados?”

Ele continua, no seu post a respeito:

“É uma pena que as autoridades tenham iniciado as suas operações por um peixe tão pequeno. Há um par de multibilionários chamados Larry Page e Sergey Brin — os criadores do Google — que fornecem enormes quantidades de links para conteúdo que é distribuído ilegalmente. Aliás, tal como toda a gente sabe, eles na verdade hospedam uma grande quantidade de conteúdo ilegal no seu próprio site de vídeo, o YouTube.

Será que a mensagem é que é menos criminoso hospedar conteúdo ilegal no YouTube do que meramente linká-lo de sites como o TV Links? Ou será que o FACT (Federation Against Copyright Theft) e a polícia não se metem com quem quer que seja poderoso o suficiente para dar o troco? Será que o New Freedom blog está correcto quando diz, sobre o Google: “They just have so much money that they have become above the law.“?

Schofield remata o parágrafo seguinte com uma afirmação profunda:

“Será que furtar numa loja é visto como aceitável se tens um emprego decente, mas considerado criminoso se és desempregado e estás esfomeado?”

Pensem nisso.

Censura…

Pelas suas próprias palavras, “Test any website and see in real-time if it’s censored in China”.

Gmail para todos!!

O Gmail finalmente abandonou o sistema de criação de contas apenas por convite. Agora, qualquer pessoa pode criar a sua conta! Vê por ti próprio:

https://www.google.com/accounts/ServiceLogin?
service=mail&ltmpl=xena&hl=pt-BR

Vale a pena, uma conta no Gmail actualmente contém quase 3 GB (2.817 MB no momento em que escrevo, e a crescer), o que é bastante útil nos dias que correm em que cada vez mais se enviam videos e outros anexos pesados por email… Bom proveito!

3d on the web

“When information in 2D becomes so dense that searching requirements are choked then they’ll rethink in 3D space or 4D space how to reimplement solutions that can break these enormous amounts of information into sets of uniquely grouped blocks of desired information that are more easily visualized in 3D than in 2D.”

“General utilization of 3D concepts in computing is slowly becoming more understood. Except for a few sentimental reasons, no one is arguing that 2D games are superior to 3D counterparts.

Being able to orient oneself in 3-space is a natural experience despite the fact that visual capability is limited to 2D, perception of the world is in fact 3D.”

Nerdcore Rap

Did you know there was a “nerdcore” rapper called MC++?

Some quotes from his site:

“The new MC Plus+ album Chip Hop has finally been released”

“act now to get a limited edition copy of Algorhythms before it is no longer available.”
