Joe Brockmeier: Ontario Linux Fest

"Em apenas algumas horas, eu vou estar em Toronto, Ontário para o Linux Fest! Olhando para a frente à reunião da OLF e da multidão dando o Guia Musical "remix" keynote de amanhã. "Remix" porque eu tive a oportunidade de fazer na primeira vez a conversa LinuxCon em setembro, e desta vez eu estarei dando uma versão ligeiramente diferente da conversa. Vamos apenas esperar com que o projetor coopere com meu laptop, caso contrário ele será a versão "unplugged". "

Will Stephenson: Atualização do openSUSE Boosters

"Enquanto openSUSE 11.2 fica cada vez mais próximo, todos os booters estão na maioria ocupados fazendo RC1 certo e a versão final está boa. Mas nós estamos encontrando algum tempo para trabalhar nos nossos projetos de Boosting. Está sendo desenvolvido no site guarda-chuva para todos os sites frente ao opensuse.org, design e perfis de usuários. O status do "concept-site" factory.opensuse.org está sendo desenvolvido em colaboração com a equipe de manutenção, de modo que ele será usado para ver o estado dos trabalhos de manutenção (por exemplo: atualizações online) pelas versões lançadas do openSUSE. Estamos analisando o código do client do Build Service na web, para saber com o gancho lá, diversos membros da equipe que estão escovando as suas capacidades de Ruby. Está sendo discutida uma nova estrutura no opensuse-wiki list a reorganização do esquadrão de documentação de contribuinte."

Launchparties para o 11.2

"O openSUSE 11.2 está programado para ser lançado na quinta-feira, 12 novembro, 2009! Não há melhor maneira de apreciar a nova versão do que com seus colegas usuários do openSUSE! Se você ou seu grupo de usuários do openSUSE está hospedando um, vá em frente e adicioná-lo a esta lista. Se você estiver interessado em hospedar um, mas tem dúvidas, envie um e-mail a lista de marketing do openSUSE para obter mais informações. "

For Desktop Users

Ghacks.net/Jack Wallen: Filtrando SPAMs com o KMail

" SPAM. É uma palavra terrível que faz com que muitos usuários de computadores arranquem os cabelos e desejem que seu fornecedor de serviços faça um trabalho melhor de manter o spam fora da sua caixa de entrada. Mas isso não vai acontecer durante a noite. Então ... Cabe ao usuário final certificar-se de que eles dispõem de meios adicionais de prevenção de SPAM entreladas em seus clientes de e-mail. "

makeuseof/Corvida: Automatize tarefas de blogs com o Press This para Wordpress

"Não ir para o seu painel de blogs Wordpress, por vezes, parece que o prelúdio de uma tarefa difícil? Você não está sozinho em seus sentimentos. Felizmente para nós, os desenvolvedores Wordpress tiveram coração (e cérebros) para desenvolver uma solução automatizada de blogs que pode apagar o nossos receios dos painéis ".

Worldlabel.com/Nathan Willis: Etiquetas rápidas e layout de cartões com o Gimplabels (Open Source)

"Akkana Peck’s Gimplabels é um conjunto de scripts para o editor de imagens Gimp, que tornam a criação de etiquetas e cartões de visita uma moleza. Um pacote .tar está disponível no site, mas o conteúdo é simplesmente um script do Gimp chamado labels.scm e os utilitários necessários para reconstruir labels.scm Gimplabels foi originalmente escrito para uma versão mais antiga do Gimp, por isso, se você estiver usando a versão atual (2.6) e ele funcionar, tente reconstruir as instruções dentro do pacote. Você deve ser capaz de instalar o script copiando-o para o diretório /scripts/ dentro da sua pasta de configuração Gimp (ie, /home/username/.gimp-2.6/)."

For Developers and Programmers

Pavol Rusnak: Uso incorreto do LD_LIBRARY_PATH

"Muitos dos programas que trazem suas próprias bibliotecas usam o seguinte trecho em seus scripts embutidos: export LD_LIBRARY_PATH="$LD_LIBRARY_PATH:/caminho/da/minha/biblioteca" Isso permite que o vinculador encontre as bibliotecas necessária, mesmo se eles estão localizados nos diretórios padrões (que são definidos pelo /etc/ld.so.conf). A princício, isso parece OK, mas cria um problema, no entanto. Quando o $LD_LIBRARY_PATH estiver vazio depois da atribuição, o novo valor iniciará com dois pontos. Quando nós rodarmos o wrapper do programa, o vinculador dividirá a variável em substrings e terminará com um caminho vazio. Isso indica a busca por bibliotecas no diretório de trabalho ATUAL, Que pode causar problemas ou até mesmo uma ameaça à segurança."

ddj.com: Ferramentas de Análise de Performance para Desenvolvedores de Linux: Parte 1

" Com o advento dos provessadores Inetl Atom e processadores multicore, a arquitetura de processadores Intel está proliferando um número de novos segmentos de mercados, mais notavelmente sistemas embarcados com bom desempenho é essencial. Em paralelo, com essa tendência, Linux está tornando-se uma oppção para sistemas operacionais embarcados. As duas tendências combinadas representam um problema ineressante: "Como tirar o máximo de proveito de minha aplicação embarcada rodando em uma plataforma Intel e em um sistema operaiconal de propósito geral?" Durante todos os tipos de desenvolvimento de aplicações, chega um momento em que um certo nível de análise de desempenho e de perfil é necessário, seja para corrigir um problema ou melhorar o desempenho atual. Se trata de uso de memória e vazamentos, uso de CPU, ou uso de cache, análise de perfis e seria quase impossível sem um conjunto de ferramentas correto. Esse artigo busca ajudar desenvolvedores a entender as ferramentas mais comuns disponíveis e a escolher a ferramenta mais apropriada para a análise específica de performance necessária."

HOWTO: KConfigXT com PyKDE4

"Se você leu sobre o KDE Techbase, ou se você desenvolve aplicativos para o KDE, você pode ter ouvido sobre o KDE's KConfigXT. Esta é uma extensão do KDE’s KConfig, e pode ser usada para gerar uma agradáveis janelas de configurações com múltiplas páginas sem o menor esforço, também tendo o cuidado de poupar e aplicar as suas configurações. Em suma, algo realmente puro! Mas existem problemas quando utilizá-lo com vinculações de linguagens interpretadas (como PyKDE, que é o que eu uso)."

For System Administrators

nixCraft/Vivek Gite: Linux Tuning The VM (memory) Subsystem

"I've fast RAID-10 disk subsystem with multiple SCSI disks. Apps running under modern Linux kernel don't write directly to the disk. They write it to the file system cache which is managed by Linux kernel virtual memory manager. Since I've high performance RAID controller I need to decrease the number of flushes. How do I tune virtual memory subsystem under Linux operating systems for better performance?"

HowtoForge/Falko Timme: Installing Apache2 With PHP5 And MySQL Support On OpenSUSE 11.1 (LAMP)

"LAMP is short for Linux, Apache, MySQL, PHP. This tutorial shows how you can install an Apache2 webserver on an OpenSUSE 11.1 server with PHP5 support (mod_php) and MySQL support."

LinuxPlanet/Carla Schroder: More Linux Remote Networking Tips and Tricks (part 2)

"Last week we looked at some good ways to use OpenSSH and SSHFS for easy file sharing on the LAN. Today we're going to review how to use encryption keys instead of password logins. Using key pairs is less flexible but more secure because it's like using a key lock instead of a combination lock. There is no way to brute-force a password, you don't have to give away system passwords, and only users who possess the key can get in."

Ekee packages for openSUSE

"Ekee is a graphical LaTeX equation editor that allows the typeset equations to be dragged and dropped to OpenOffice.org or saved as high quality images to be used in other word processors and presentation softwares. Packages for openSUSE 11.1 are available in my home repository on the openSUSE buildservice and soon they should be included in the science repository too."

KdeNews/Sebastian Kügler: Developer Days 2009: Qt Grows

"Last week, Munich saw the 2009 Edition of the Qt Developer Days. Qt Developer Days is a Qt-focused software conference which is held yearly in Europe and the U.S. The American edition will be held at the start of November in San Francisco. 700 attendants and more than 70 Trolls made this edition the biggest Developer Days to date. Qt Development Frameworks had invited a group of KDE developers to the conference, more well-known heads from the KDE world were sent by their respective employers. The days brought training sessions around Qt and many interesting presentations ranging from higher level topics such as the future roadmap for Qt to topics related to Qt programming with techniques and technologies such as the Model/View Framework, QGraphicsView, WebKit, multithreading and many more. Read on for a more detailed report of what has been revealed and talked about during the three-day conference in Munich's Hilton Park hotel."

"As explained on Userbase, Nepomuk is a promising new technology which aims to make the user's data easier to find. Not only through the now common search and indexing, but also by making use of more complex relationships between documents, contacts and all sorts of data. While the full potential of Nepomuk is still shrouded in mystery for most of us, for developers it is an exciting area of work where academic research and Free Software development come together. Nepomuk is looking for new developers, read on to find out how you can help!"

Marco Barisione’s Weblog/Marco Barisione: Contacts on Maemo

"After the Maemo Summit the details on the address book application and framework in Maemo 5 are finally completely public so I can openly talk about what I worked on during the past year and, even better, I actually have a smartphone that runs this software! (Thanks to Nokia that gave out 300 N900s, but I will talk about this in my next post)"

Rob Bradford: GNOME in Moblin myzone

"Howdy, i’m sure most people are aware of the recent release of Moblin 2.0; a user experience for netbooks. I’m going to write a few blog posts about how the Moblin user experience is built on the awesome technologies in the GNOME platform. So first up, let’s look at the Myzone, we’re starting here since this is the first thing I really worked on in the Moblin UX and i’ve been able to see it through from early ideas to the 2.0 and 2.1 releases."

Joe Brockmeier: Know your audience: Going beyond “true believers”

"In line with my post last week about how to market FOSS, and what to lead with, Seth Godin talks about listening to the true believers. In short, if you look at just about any topic area you’ll find “true believers” who are deeply involved with the issue at hand, but largely out of sync with the larger market."

Richard Bos: Kolab becomes available again for openSUSE

"Kolab on openSUSE made some very good progress since my last blog update on this topic. The most visible thing to the system administrator is that all Kolab required packages are available on the build service for openSUSE_Factory which will become openSUSE_11.2 very soon and its and predecessors."

Aaron Seigo (aseigo): two simple things to improve the user experience

"There's a lot of discussion about user experience around these days. That's good, though sometimes the focus is kept on solving "big issues" and a lot of the small everyday type things get missed. Here are two things that I personally run into a bit too regularly that can be easily improved on and which really do help with the user experience."

Pascal Bleser: Packman upgrading to SVN OBS

"Don't panic if you notice insane amounts of updates to packages in the Packman repository for openSUSE. We are currently switching from OBS (openSUSE Build Service) version 1.6.0 to the latest SVN trunk HEAD, which requires some experimentation and also caused a complete rebuild (for unknown reasons)."

Brent McConnell: Do People Trust You and Your Community?

"Trust influences nearly every interaction we have during any given day. Every communication, every action, every conversation is shaped in some way by the trust and reputation that we infer on the interacting party. It is the currency communities, both online and offline, trade in. Without trust, lasting relationships can't be built and authentic communities can't be maintained. As a Community Leader, part of our job is to build reputation and trust for our communities and the people associated with them. This may sound easy, but it can be very hard since you rely on the actions of others for much of your community's reputation and trust. Think about it... You may be the most trustworthy and reputable person in the world, but if your community is acting in the wrong way, your efforts may be for naught."

Andreas Jaeger: Developing for openSUSE using Devel Projects

"With the opening of the openSUSE distribution so that everybody can contribute to packaging, we introduced the concept of devel projects and I’d like to explain a bit more what they are and why they are important."

Reports

h-online/Thorsten Leemhuis: Kernel Log: Coming in 2.6.32 (Part 1) – Network subsystem and network drivers

"Between Thursday evening and Friday morning, Linus Torvalds released the fourth release candidate of Linux version 2.6.32, although, due to the typing error in the first release candidate (RC1 was mis-labeled RC2), it is called 2.6.32-rc5 instead of 2.6.32-rc4. Torvalds released this version only a few days after RC4, as he and many other kernel hackers will spend the weekend travelling to this year's Linux Kernel Summit held in Tokyo next week; therefore few changes are expected to make their way into the Linux kernel's source code management system during this time."

blogwire: Migration from Mac to Linux

"Most know the very philosophies behind both of those operating systems are very different. Because of that, many often need a bit of hand-holding in order to gain some semblance of ease when going from one to the other. But does the same hold true when trying to migrate from Mac OS X to Linux? Since OS X originally contained portions of NetBSD and FreeBSD one would think so. But the current OS X is not the same as the original OS X that hit the shelves March 24th, 2001. Because of this, the migration of OS X to Linux could use a little bit of that same hand holding necessary for the Windows users."

LinuxCrunch/Fahad: A sneak preview of new OpenOffice 3.2 part 1"

"The last developer milestone ( DEV300m60) of OpenOffice.org has been released. The next version of OpenOffice.org 3.2 has more than 42 features and 167 enhancements . The final version is expected to be available at the end of November 2009.Open Office 3.2 Many companies have contributed to this version like RedHat , RedFlag and IBM, making OpenOffice more stable and useful. I couldn't stop myself from seeing new features and enjoying them. So I downloaded DEV300m60 version. After playing with it for many days I could say that OpenOffice developers have done very good work in it. Well done ! I will review in this post some interesting features : more secure , faster , easier and more international. ...]

Unixmen/M. Zinoune -Zinovsky-: A math teacher with his students bring Desktop4education to austrian schools

"In 2003 Helmuth Peer, a math teacher at the Weiz secondary school (Bundesgymnasium) decided that it was time to migrate the schools' IT system to a new platform, that would be easy to set up, easy to maintain, and easy to connect via a network. Together with his students, which he involved in the project, he searched for a solution that would allow for customization and correspond to the needs of each school level concerned. He found that the Linux distribution openSUSE 11.1 would qualify as a suitable solution, and building a system on this basis seemed sustainable in the future and the right choice to him. ..."

Phoronix/Michael Larabel: NVIDIA Developer Talks Openly About Linux Support

"In late August we started asking our readers for any questions they had for NVIDIA about Linux and this graphics company's support of open-source operating systems. Twelve pages worth of questions were accumulated and we finally have the answers to a majority of them. NVIDIA's Andy Ritger, who leads the user-space side of the NVIDIA UNIX Graphics Driver team for workstation, desktop, and notebook GPUs, answered these questions. With that said, there are some great, in-depth technical answers and not the usual marketing speak found in many interviews. While Linux is our focus, Andy's team and his answers for the most part apply equally to NVIDIA drivers on Solaris and FreeBSD platforms too. There are many questions that range from the status of new features in their proprietary graphics driver to why it is unlikely there will be any official open-source support from NVIDIA to download percentages of their Linux driver."

Satoru Matsumoto: 100th Kernel Code Reading Party - Japanese Linux enthusiasts have deepened friendships with kernel hackers

"This week, 2009 Linux Kernel Summit and Japan Linux Symposium are taking place in Tokyo and so many Linux kernel hackers are gathering in those events from across the world. Unfortunately, I myself couldn't attend the events, but there was a good opportunity to talk with some of those developers.

The 100th Kernel Code Reading Party was held by YLUG (Yokohama Linux Users Group - one of the most active LUG in Japan) last night in Akihabara, the town known as Mecca of electrics and cybercultures in Japan and many attendee of the events showed up for the party. The funny thing is that the party for Linux enthusiasts took place on the same day, when Windows 7 released. :-P"

h-online.com/Stallman opposes Oracle's takeover of MySQL

"Following on from MySQL founder Monty Widenius, Richard Stallman, president of the Free Software Foundation, and non-profit organisations Knowledge Ecology International (KEI) and the Open Rights Group (ORG) have advised European Commissioner for Competition Neelie Kroes not to grant approval for Oracle's takeover of MySQL. In a joint open letter, they argue that the takeover would restrict competition in the database market."

ComputerworldUK/Glyn Moody: Why Open Source Companies Need to Give Up Control

"I've always regarded the passionate discussions that take place within the free software world as a sign of health: it indicates people care, and that they are thinking hard about the issues. Against that background, a sudden efflorescence of posts about open source companies – what that means, how they work, and their future – is something that I've observed with a certain satisfaction. But sitting and watching isn't really my kind of thing, so I feel it's time for me to wade in with a few thoughts of my own. "

ghacks.net/Jack Wallen: Let your medical practice go open source with Gnumed

"Gnumed is an open source management tool for medical practices. If your practice (or a practice you do IT for) is in need of an electronic record-keeping system, and you do not want to have to shell out your entire IT budget for a proprietary solution, Gnumed might be the perfect tool for you."
