lubuntu | lightweight, fast, easier

Is Your Computer Stable?
Everyone breathes a sigh of relief when their newly built computer boots up for the first time, no matter how many times they've done it before. But booting is only the beginning of the story. Yeah, it boots, great. Color me unimpressed. What we really need to know is whether that computer is stable.

Although commodity computer parts are more reliable every year, and vendors test their parts plenty before they ship them, there's no guarantee all those parts will work reliably together, in your particular environment, under your particular workload. And there's always the possibility, however slim, of getting very, very unlucky with subtly broken components.

Because we're rational scientists, we test stuff in our native environment, and collect data to prove our computer is stable. Right? So after we boot, we test.

Ubuntu Amazon EC2 AMI Finder
As Ubuntu cloud images are uploaded and registered on the Amazon EC2 cloud, they are referred to as AMI (Amazon Machine Images). Each AMI is a machine template from which you can instantiate new servers. Each AMI has its own unique ID. In order to launch an instance on the EC2 cloud, you first need to locate its ID. This page helps you quickly locate an AMI ID.

Instalando o Ruby no Ubuntu Precise - Simples Ideias
Decidi criar meu próprio repositório Debian com a última versão estável do Ruby (que neste momento é a versão 1.9.3-p194). A ideia é ter um repositório sempre à mão, tanto para o ambiente de desenvolvimento, quanto para a produção. O pacote que está disponível é para as versões 32-bit e 64-bit do Ubuntu Precise, mas se você está rodando qualquer distro baseada no Debian, poderá instalar também.

Welcome to DenyHosts
DenyHosts is a script intended to be run by Linux system administrators to help thwart SSH server attacks (also known as dictionary based attacks and brute force attacks). If you've ever looked at your ssh log (/var/log/secure on Redhat, /var/log/auth.log on Mandrake, etc...) you may be alarmed to see how many hackers attempted to gain access to your server. Hopefully, none of them were successful (but then again, how would you know?). Wouldn't it be better to automatically prevent that attacker from continuing to gain entry into your system?

Como integrar o Terminal no Nautilus | Ubuntued
O Nautilus-Terminal é um pacote que enriquece o Nautilus (o explorador de ficheiros do Ubuntu) com um terminal embutido. O resultado desta combinação é um Nautilus que tem sempre à disposição um Terminal que se encontra sempre na pasta que está a visualizar. Ou seja, este software permite que sempre que mude de pasta tenha um Terminal à sua disposição para essa mesma pasta. Para além disso, e porque nem sempre é preciso, o Nautilus-Terminal permite que aparece apenas em pastas escolhidas por si, ou então que esteja sempre oculto até que necessite de o utilizar.

How to: Install a Debian/Ubuntu package (.deb) cache server - apt-cacher | Linux Operating System - Debian, Ubuntu, Fedora, Gentoo, Arch
If you have more than one PC using Debian or Ubuntu, you know that upgrading them makes most of the time download the same files more than once, and that is not good for your bandwidth. I usually forward my requests to my Squid (in my office) and to my Personal proxy Polipo at home, it works, but apt-cacher may be a better approach as the way it decides if a file stays or is erased from the cache is more appropriate for .deb package than in Squid or Polipo, as they are optimized for web surfing.

Local DNS Cache for Faster Browsing « Ubuntu Blog
You can run a DNS cache on your computer. This will speed up the process of looking up domain names when browsing. The difference is about 30-60 ms for me. Multiply that difference by the number of websites you visit a day for an approximate estimate of the speed improvement. Of course, all this would be worth it if it weren’t for the fact that setting this up is way too easy.

Transmageddon is a video transcoder for Linux and Unix systems built using GStreamer. It supports almost any format as its input and can generate a very large host of output files. The goal of the application was to help people to create the files they need to be able to play on their mobile devices and for people not hugely experienced with multimedia to generate a multimedia file without having to resort to command line tools with ungainly syntaxes.

OMG! UBUNTU!: Install Picasa 3.5 In Linux
Google this week released Picasa 3.5 for Windows and Mac. Sadly no Linux version was offered, a fact Google blamed on the lowly adoption figures they have for Picasa on Linux. I think that's a shame because Picasa is such an incredible application - its photo editing, its photo management, it's integrated web services... All are just first class. This article is about installing 3.5 as a Linux version.

Make Compiz Run Smoothly and Without Tearing | Tombuntu
For a long time it has bothered me that Compiz does not seem to run as smoothly as Metacity on my desktop system. With desktop effects switched off, moving windows around the screen would seem smoother. With desktop effects switched on, I’d also notice tearing in areas of the screen with fast motion including in videos. I was fiddling with Compiz settings recently and managed to fix the problem entirely. Now, if your graphics card struggles to run Compiz this will probably not help you. But if you have a decent graphics card (mine is a nVidia GeForce 8600 GT) give this a try if you have noticed this problem.
