Sibe 2009

by karlcow

Infrastructure provides the basic needs for society, and sustainable infrastructure systems are essential for the survival, health and well-being of a society. For developing countries, the civil and environmental engineer are at the epicenter in seeking means to enhance human life through modernization of infrastructure as evidenced by provision of shelter, water, and transport, amongst others.

The current rate of urbanization and industrialization has caused a rise in environmental issues, involving environmental mismanagement which has been associated with unforeseen global catastrophes. The problems are further aggravated with environmental degradation such as soil erosion, depletion of water resources, etc.

In order to meet these multifaceted challenges, proper planning, implementation and verification exercises are required, via an integrated, multidisciplinary and holistic approach. The global momentum for sustainable development must now lead to practical applications of the engineering and science of sustainability.

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).

USGS Twitter Earthquake Detector : GIS Lounge - Geographic Information Systems

by karlcow

The USGS is now testing out Twitter to collect early response information about earthquakes: “the USGS is developing a system that gathers real-time, earthquake-related messages from the social networking site Twitter and applies place, time, and quantity data to provide geo-located earthquake detection within 60 seconds of an event’s origin time.“ Social media can be a valuable tool in helping to assess earthquake hazards through anecdotal information from hundreds and potentially thousands of local users.

Toward urban systems design « Adam Greenfield’s Speedbird

by karlcow

you said: “Especially given the by-now-clichéd recognition that we’ve decisively become an urban species”

It is indeed very interesting to think about urban systems design given there was a major move toward cities. That said I have the feeling that this move comes with, at least, three issues:

1. access to the “thought” urban environment,

2. the space left where 50% of the population is still living,

3. the space of this growth

There are many areas in the world where the growth of the cities is made by people without access or a limited access to the thought urban environment. Poor people living in slums or just in a space which is not part of the work of urban planner per say. In a recent exhibition about slums I went, it was very interesting to see that the organic structure of the slums was making possible for the individuals to create a rich and meaningful space, driving sometimes to less criminality than more traditional areas of the city. The slum is a forced collective creative space for survival.

The rest of the population, the 50% living in deserted areas are the forgotten of this story. It’s indeed more “fun”, interesting for researchers, sociologists to observe and think about the density in urban space (richness of interactions) more than the low level of activities in the “countryside”. Though there are equal challenges there in terms of design and space organization, access to services, etc.

Finally, is it really cities which are growing? What we call urban space often relates to the city center, but I have the feeling that the growth is happening in the in-between space (suburbs), which is again a complete disaster in terms of design, even more so in rich countries. The private space is becoming a space of non-creativity, dead areas of non activities. Someone, who wants to start a small business in between two buildings on the grass of a random suburb of a rich city, will not last for very long. Complete different dynamic than the slum where unregulated areas give the opportunity of creative solutions for surviving or living.

Plumber Jack: Python Logging 101

by karlcow

Basic logging of errors to text files and system logs is an old technique, but not very flexible. In this post, I introduce a logging system for the Python programming language. This system, while it borrows ideas from other systems, is not a port of anything but an independent implementation for use by Python developers.The logging package has been part of Python since Python 2.3 (released in 2002).

Coding from Scratch: A Conversation with Virtual Reality Pioneer Jaron Lanier, Part One

by karlcow & 1 other

answer Right. And it results in a type of error that doesn't teach you anything. You have chaotic errors where all you can say is, "Boy, this was really screwed up, and I guess I need to go in and go through the whole thing and fix it." You don't have errors that are proportionate to the source of the error. And that means you can never have any sense of gradual evolution or approximate systems. So, the real difference between the current idea of software, which is protocol adherence, and the idea I'm discussing, pattern recognition, has to do with the kinds of errors we're creating. We need a system in which errors are more often proportional to the source of the error.

Evaluation of Digital Repository Software at the National Library of Medicine

by parmentierf
The National Institutes of Health (NIH) National Library of Medicine® (NLM) undertook an 18-month project to evaluate, test and recommend digital repository software and systems to support NLM's collection and preservation of a wide variety of digital objects. This article outlines the methodology NLM used to analyze the landscape of repository software and select three systems for in-depth testing. Finally, the article discusses the evaluation results and next steps for NLM. This project followed an earlier NLM working group, which created functional requirements and identified key policy issues for an NLM digital repository to aid in building NLM's collection in the digital environment.

About | Mapdiva, LLC

by karlcow

You know how powerful maps are – to communicate, to convince, to plan, to dream. But existing mapping tools make hard work of a good map. General-purpose graphics programs know nothing about mapping and can be an exercise in frustration. And GIS» geographic information systems (GIS) are used to manage and analyze geospatial data; though powerful for those purposes they often produce unattractive “GIS-looking” maps!have a steep learning curve, are expensive, and lack high-quality presentation graphics.
