O site da IBM tem muita e boa info sobre GNU/Linux, desde dicas deste tipo até aos cursos de preparação da certificação LPI, que já havia mencionado numa outra entrada.

Lazy Linux: 10 essential tricks for admins

Trick 1: Unmounting the unresponsive DVD drive

The newbie states that when he pushes the Eject button on the DVD drive of a server running a certain Redmond-based operating system, it will eject immediately. He then complains that, in most enterprise Linux servers, if a process is running in that directory, then the ejection won’t happen. For too long as a Linux administrator, I would reboot the machine and get my disk on the bounce if I couldn’t figure out what was running and why it wouldn’t release the DVD drive. But this is ineffective.

Anúncios

Dicionário de GNU/Linux e mais algumas coisinhas :)

Já tem alguns anitos mas não deixa de ser uma fonte preciosa de informação.

Na mesma página temos também links para o dict e para o ‘Computer Dictionary’

Linux Dictionary

This document is designed to be a resource for those Linux users wishing to seek clarification on Linux/UNIX/POSIX related terms and jargon. At approximately 24000 definitions and two thousand pages it is one of the largest Linux related dictionaries currently available. Due to the rapid rate at which new terms are being created it has been decided that this will be an active project. We welcome input into the content of this document. At this moment in time half yearly updates are being envisaged.

Welcome to the Computer Dictionary Project

Computer Dictionary is an open source project, released under terms of the Creative Commons ShareAlike 2.0 license, that aims to develop a Docbook XML glossary database containing definitions of computing nomenclature. The primary application for the source is realized in context of Docbook XML-based publishing systems. However, as a desired side-effect, the glossary is also available online as a ‘browsable’ reference.

What makes this project unique is that it is the first free and open glossary database to be developed specifically for use with Docbook XML-based publishing systems.

Converter ficheiros de texto em MP3, yep… é isso mesmo! (edit)

Numa das minhas surfadas pela web, encontrei este interessante “howto”, como converter ficheiros de texto em mp3, usando para tal o Festival, ou seja, vamos fazer com que o nosso GNU/Linux leia para nós.

Infelizmente o Festival ainda só entende o Inglês (UK/USA) e o “Espanhol”.

Apesar do documento mencionar o formato mp3, eu optaria pelo excelente Ogg Vorbis.

Mais uma vez usando uma distribuição Debian GNU/Linux ou Debian based, parecendo que não facilita as coisas 😉

Festival

The Festival Speech Synthesis System

Festival offers a general framework for building speech synthesis systems as well as including examples of various modules. As a whole it offers full text to speech through a number APIs: from shell level, though a Scheme command interpreter, as a C++ library, from Java, and an Emacs interface. Festival is multi-lingual (currently English (British and American), and Spanish) though English is the most advanced. Other groups release new languages for the system. And full tools and documentation for build new voices are available through Carnegie Mellon’s FestVox project (http://festvox.org)

Linux on Desktop: Convert text files to MP3 under Linux

Convert text files to MP3 under Linux

Even though I am not a fan of audio books and the only thing I use my iPod for is listening music still while exploring Festival(which is basically a General multi-lingual speech synthesis system) I found out that it’s very easy to convert normal text files into mp3 using festival . Now this could be especially useful for people who either listen to audio books or people who have difficulty in reading.
