Recyclable Paper Laptop by Je Sung Park » Yanko Design

by karlcow

I quite agree with Je Sung Park when he says that disposable cameras and cell phones have gained acceptance, so why don’t we take the next step and bring out a disposable computer. His Recyclable Paper Laptop is quite a raw version and could do with some refinement. It uses recycled paper or pulp material all packed in layers. This is so that you can easily replace the damaged portions (even corrugated paper will tear easy). The vibe of a Paper Laptop is intriguing, I kno eventually someone will figure out the tech bit, so let’s see who will take the bait.

four

by blackgoldfish
Today, my baby, you turn four. When did this happen? Was it not just yesterday that I had to put you inside my coat to keep you warm? Now look at you! Almost as tall as your sister with just as much spunk. Happy Birthday my punkin. What four is looking like so far: You pronounce your Rs as if you lived in Boston your whole life- A feather is a featheh. You sing from dawn to dusk- singsong monologues of your life. You eat a peanut butter sandwich every single day. You wake up hungry and must immediately eat a granola bar or your world collapses. You love coffee Your favorite color is blue You swing so high that I have to hold in my own concern because I see how much you need to do it. When you get mad, I suggest people step away, as you get a bit ferocious. You will brush my hair four an hour straight, and therefore I'll not ever cut it. You like to get your back lightly scratched, just like Mama. Happy Birthday, my sweet girl. Every day with you is a treasure and a surprise. I love you.

MD5SUM (Matéria)

by tadeufilippini (via)
Matérias / Matéria MD5SUM Como verificar a integridade de arquivos puxados da Internet Por Fábio Melatti em 21/Out/2003 O MD5SUM é um programa de domínio público usado para verificar mensagens criptografadas e integridade de arquivos. Portanto quando as ISOs são feitas é usado o MD5SUM para que você possa ter certeza que a ISO que foi baixada é exatamente igual a que está no servidor. Por ser uma ferramenta de 128-bit te dá uma excelente garantia de que o seu arquivo está exatamente igual ao original, a menos que os md5sums sejam diferentes ;-), pois qualquer alteração em meio bit do arquivo resultará em um conjunto de caracteres totalmente diferentes. Quando o MD5SUM é rodado sobre um arquivo é gerado um conjunto de 32 caracteres, semelhante a esse: dddb5786219f57fef20b0ae3616afc67 isoqualquer.1.3-5.iso Pronto, agora que sabemos o que é e para que serve, vamos para a parte prática. As distribuições Linux por padrão já incluem o programa MD5SUM, por isso não há muito trabalho, basta abrir qualquer terminal e digitar: md5sum isoqualquer.1.3.iso E depois de algum tempo, afinal de contas estamos verificando arquivos de 650 MB em média, ele retornará um conjunto de caracteres, então é só conferir com o md5sum do servidor. É claro que agora vem a pergunta clássica, mas eu estou usando o Windows, como vou usar o MD5SUM? Ai você terá duas opções, existem aqui mesmo no Superdownloads versões de MD5SUM para rodar no ambiente gráfico do Windows e em janela do DOS, fica a sua escolha, as duas fazem exatamente a mesma coisa. Usando a versão para janela do DOS é só ir para a pasta em que está a ISO e dar o mesmo comando acima, como no Linux. Se você tiver o problema de limite de caracteres com o nome do arquivo do tipo, 8 caracteres para o nome e 3 para a extensão (8.3), renomeie o arquivo para outro nome similar que fique dentro desses limites. Caso queira mais opções com o MD5SUM, digite: md5sum -h Na versão gráfica antes de mais nada é necessário instalar o programa, depois rode e escolha a pasta onde está a ISO e clique em "create sums", vá tomar um café, e depois de algums minutos você verá um monte de números e letras na frente do nome do arquivo, é o seu md5sum. Dicas importantes Caso o md5sum da ISO que você baixou não bater com o que está no Superdownloads, antes de apagar e começar a baixar novamente, verifique o md5sum do servidor de onde você baixou, por exemplo, se você utilizou este link "ftp://ftp.univie.ac.at/systems/linux/Mandrake/iso/Mandrake91-cd1-inst.i586.iso", é só tirar o nome do arquivo e abrir no seu navegador, ficaria assim esse link "ftp://ftp.univie.ac.at/systems/linux/Mandrake/iso/", lá estará a relação das ISOs e o md5sum. É dificil, mas ocasionalmente pode haver uma pequena diferença nas ISOs de um servidor para outro, o que resulta em um md5sum diferente. Para fazer o download das ISOs é preciso usar o modo binário (binary mode), pois se for usado o modo ASCII (como a maioria dos navegadores fazem), com certeza haverá alteração dos dados durante a transferência e sua ISO será corrompida e o m5sum nunca irá bater. Por isso sempre utilize um cliente de FTP ou gerenciador de download com a função de continuar downloads interrompidos (muito importante considerando o tamanho dos arquivos) e que faça o download em modo binário (binary mode).

getElementsBySelector - CSS Query Selector for HTML DOM < Scripts < Python < Bin-Co

by karlcow

getElementsBySelector is a python function which takes a standard CSS style selector and returns an array of elements objects from the document that match that selector. This is a frequently used function in JavaScript - if you use a library. Its kind of meaning less to have this function in the server side - unless you are doing screen-scarping. Then its very useful. Recently, I had to work on a Django app that does a bit of screen-scrapping - so I created this function to aid me.

Charles Apple » Blog Archive » First look: Redesign of the Washington Post

by sbrothier
Long the epitome of understated class, the Post became just a little bit more classy overnight. It’s not a major redesign, but then again, we didn’t expect one. When this thing was announced back in February, it was referred to as a “tweak.” And a tweak is that the Post got. And it’s a good thing, too — the Post didn’t need a major overhaul.

RMagick Download Page

by ycc2106 & 2 others
RMagick is an interface between the Ruby programming language and the ImageMagick® and GraphicsMagick image processing libraries. RMagick can be more difficult to install than the typical Ruby extension. First you have to install ImageMagick or GraphicsMagick, and those libraries require a lot of other libraries. Nevertheless, the process can be made easier with a bit of planning. On this page I'll try to answer the most common questions about installing RMagick. Give it a quick scan before you start downloading files.

technobabbler » Blog Archive » drive a webcam with python

by karlcow

I bought a USB webcam off of eBay quite some time ago, and I decided to connect it to my telescope with a little bit of hardware hackery. I'll have to see about posting a writeup on how I did that at a later time. Anyway, when I installed my camera software, I quickly found how horrible the program was. It gave a tiny preview of what the camera saw, and had no way of capturing images or video without waaaay too many clicks of the mouse. That's when I decided to write my own in Python.

Securing a Domain: SSL vs. DNSSEC

by marco
There has been quite a bit of talk lately about the best way to secure a domain, mainly centered in two camps: using Secure Socket Layer (SSL), or using DNS Security Extensions (DNSSEC). The answer is quite simple—you should use both.

Our Wedding: Part 2 | The uber-emotional ceremony

by blackgoldfish
Still, I wanted to tie in our fair / carnival / summer party-bbq theme a bit so I made this bunting (banners or flagging or garlands, whatever you want to call them) to go along the aisle. We shopped for a couple months to find cool patterned fabrics in our wedding colors.

Testing Google's Rich Snippets RDFa support from Philip Taylor on 2009-09-12 (public-rdf-in-xhtml-tf@w3.org from September 2009)

by night.kame & 1 other

I tested it a bit, and it seems that what's implemented in that tool bears very little relation to RDFa. It's not simply a buggy implementation - it's not even attempting to handle RDFa remotely correctly.

Comme d'habitude, Google et ses milliers de docteurs en sciences est infichu d'appliquer un standard, si minime soit-il, du premier coup. Il faut dire que les docteurs en sciences chez Google sont tous dans les département "datamining" et "publicité". A la programmation, ils n'ont laissé que les prag-ma-ti-ques.

Tornado Web Server

by karlcow 1 comment

Tornado is an open source version of the scalable, non-blocking web server and tools that power FriendFeed. The FriendFeed application is written using a web framework that looks a bit like web.py or Google's webapp, but with additional tools and optimizations to take advantage of the underlying non-blocking infrastructure.

PostRank

by ycc2106
The PostRank data service can be used in many different ways. One example is filtering existing feeds to reduce the quantity of items a feed reader is presented. PostRank helps you engage with information that interests you. Read what matters and learn as much or as little as you want about topics, from every little bit to just the hottest news.

my secret to happy relationship - michael

by blackgoldfish
The idea is that if there are enough, and they're well hidden, you'll discover new ones (in your pockets, in the luggage) daily throughout your whole trip. It makes being apart a bit more bearable!
