For functions that operate on string positions, the first position is numbered 1.

Try dpkg -l | grep twhirl or rpm -qa | grep twhirl, and you’ll see what I mean.

Afterwards, just install the latest Twhirl (0.8.7, as I write this post).

Twhirl should’ve post this bugfix on their page…

1/2 of my christmas presents from me to myself.

Spammer-X describes one spam “case”: he bought two million email addresses for $200.00 (chapter 2). He runs the email addresses against a list of known “bad/filterable” lists and then sends 10,000 spam emails, using eight proxy servers, in 17 minutes. He’s able to track how many people whom he emailed visit the site he’s promoting (which happens to be a porn site in the case he describes). After 12 hours, he’s got 967 people to click onto his link. Many of those clicked from a “bulk mail” folder. And nearly all clicked to another page within the site. Out of the 967, one registers for monthly membership on the site. Spammer-X suggests that this case is fairly typical.

Nearly ten percent of the recipients clicked on a link from an unknown source. Spammer-X claims he made nearly $3000 for about 30 minutes of work. So his motivations are clear. But why are individuals responding? Spammer-X claims that he’s providing email readers with links they want but won’t admit they want.

Não conheço ninguém que admita ler SPAM, ou utilizá-lo para qq coisa. Mas se calhar é só porque ninguém admite?

RESTful web services

CouchDB

Apache CouchDB is a distributed, fault-tolerant and schema-free document-oriented database accessible via a RESTful HTTP/JSON API. Among other features, it provides robust, incremental replication with bi-directional conflict detection and resolution, and is queryable and indexable using a table-oriented view engine with JavaScript acting as the default view definition language.

CouchDB is schema-less, eventually consistent, and speaks HTTP and JSON natively. One of the coolest pieces is the view layer, which uses MapReduce(http://en.wikipedia.org/wiki/Mapreduce) with map and reduce functions provided by JavaScript.

It replicates well in any topology you desire. Finally, we have master-master replication that works well. It can do this because it doesn’t assume away the problem of data conflicts. Instead, CouchDB provides tools to deal with conflicts.

Document oriented as in Object oriented. O ponto é que o paradigma muda. Esqueçam tabelas, colunas e olhem para objectos.

Para além de poupar a existência de um ORM, performance-wise é interessante neste momento para Reads, nada para Writes e, como guarda versões dos objectos, ainda menos interessante em necessidades de storage:

XMPP

The Extensible Messaging and Presence Protocol (XMPP) is an open technology for real-time communication, which powers a wide range of applications including instant messaging, presence, multi-party chat, voice and video calls, collaboration, lightweight middleware, content syndication, and generalized routing of XML data.

Dojo

Dojo is arguably the most feature-complete AJAX toolkit today. Using Dojo’s data stores to create a clean separation of concerns from the server-side.

Server Side Java Script

Nas próximas semanas deverá aparecer a primeira Web Development Framework baseada nesta tecnologia (e feita @pt).

Uma interessante apresentação do Celso. sobre a estrutura da tecnologia utilizada na startup dele. Os slides estão aqui.

GitHub

Not only is Git the new hotness, it’s a fast, efficient, distributed version control system ideal for the collaborative development of software.

GitHub is the easiest (and prettiest) way to participate in that collaboration: fork projects, send pull requests, monitor development, all with ease.

Just a definitely cool gadget to have. I’ve read about it almost a year ago, but I’ve only seen it live @codebits.

TVBgone

Your TV-B-Gone® universal remote control resembles other TV remote controls, but is different in two important ways. First, it only has a power button that allows you to switch a TV on or off. You control when you see, rather than what you see. Second, the device is so small that it easily fits in your pocket, so that you have it handy whenever you need it wherever you go: airports, bars, restaurants, laundromats, etc.

Here’s a geek opensource gadget

PS: Peço desculpa à IUZ pelo engano!

Uma boa novidade foi a presença da Make Magazine, e de um espaço virado para o hardware - sempre uma experiência gira com geeks. A meu ver, tirando a comida e dois ou três acidentes com Segways, esta edição demonstra uma evolução positiva. Sem stresses com rede… cablada, que wifi embora esteja muito melhor que a edição passada, continua com muitos clientes por AP.

Os momentos rockband foram também muito divertidos, talvez mais do que as experiências musicais do ano passado.

Estruturalmente, pareceu-me um Codebits com muito menos sobressaltos do que em 2007, mas penso que depois das sessões no primeiro dia havia possibilidade de se fazerem muitos mini-concursos (à la MCP). Mas continua a sua marca como ponto de reciclagem para o pessoal ligado às TI, onde nos vamos apercebendo e partilhando experiências, testes e desenvolvimentos pelos outros geeks semelhantes a nós.

Ter retirado a firewall do Windows é que não me parece muito porreiro, mas desde que não se esqueçam disso quando instalarem o SO, parece-me lindo

Mais uma grande frase do MV:

Sou geek, sou nerd, gosto de explorar a tecnologia(…) se é isso que chamam de hacker, é isso que eu sou chamem-me hacker à vontade.

PS: Man, eu também gostava de ter uma Arcade igual à do Celso Martinho
