Networks, Crowds, and Markets: A Book by David Easley and Jon Kleinberg

by karlcow

Over the past decade there has been a growing public fascination with the complex "connectedness" of modern society. This connectedness is found in many incarnations: in the rapid growth of the Internet and the Web, in the ease with which global communication now takes place, and in the ability of news and information as well as epidemics and financial crises to spread around the world with surprising speed and intensity. These are phenomena that involve networks, incentives, and the aggregate behavior of groups of people; they are based on the links that connect us and the ways in which each of our decisions can have subtle consequences for the outcomes of everyone else.

Networks, Crowds, and Markets combines different scientific perspectives in its approach to understanding networks and behavior. Drawing on ideas from economics, sociology, computing and information science, and applied mathematics, it describes the emerging field of study that is growing at the interface of all these areas, addressing fundamental questions about how the social, economic, and technological worlds are connected.

The book is based on an inter-disciplinary course entitled Networks that we teach at Cornell. The book, like the course, is designed at the introductory undergraduate level with no formal prerequisites. To support deeper explorations, most of the chapters are supplemented with optional advanced sections.

Linkcontainer Formats : DLC (Download Link Container), CCF (Cryptloads's containerformat, broken) and RSDF (Rapidshare Downloader Format, broken) - [JDownloader]

by decembre
Link-Containers are encrypted linklists. Using Containerfiles, it is very comfortable to provide many links at once. Moreover a encrypted container hides it's links from curious eyes. There are three different container formats: DLC, CCF (Cryptloads's containerformat, broken) and RSDF (Rapidshare Downloader Format, broken). JDownloader can handle all of them. DLC :Download Link Container , After RSDF and CCF got cracked, the JD-team decided to create a new Containerformat with the objectives to allow anybody to create DLCs and to allow every Loader to read DLCs. In order to live up to those expectations DLC uses a client-server encryption. Links are processed locally while the keys are distributed and recrypted by a webservice. To date, the DLC encryption has not been broken.

Then, to keep all the previous links pointing in the right direction, we created a customizable scheme of Django regular expressions and Apache mod_rewrites.

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).
