In part 1 of this series we learned how to measure how much power our systems are using, both hardware and software, and some tricks for reducing power usage without degrading performance. Today we're going to dive into the world of power management on laptops: ACPI, APM, hard disk spindowns, and spinups.
In my next three articles I'll profile three native Linux software synthesizers (a.k.a. softsynths). I'll introduce their basic synthesis architectures and program operations, then I'll guide my readers briefly through the process of creating a new sound for each synth profiled. Our voyage begins with Nick Dowell's Analogue Modeling SYNTHesizer, better known as amSynth.
Due to GVFS replacing GNOME-VFS in the GNOME desktop environment, in Ubuntu 8.04 my preferred way of installing fonts doesn’t work anymore. In GNOME versions prior to 2.22 you could navigate to fonts:// in the file browser and drag and drop to install fonts. Doing this in Ubuntu 8.04 gives the error:
Nautilus cannot handle fonts: locations
Version 0.46 of the open source vector graphics editor Inkscape is out, showcasing new tools, new effects, new filters, and a host of interface and speed improvements.
A member of several Ubuntu collaboration teams, including Ubuntu-Artwork has recreated the ubiquitous Human Theme for the iPhone. He plans on updating it for a simultaneous release with Hardy Heron. I was able to catch up with the creator and ask him a few questions.
Midori is a GTK web browser that uses the WebKit rendering engine. It’s nowhere near as polished, feature-rich, or stable as browsers like Firefox and Konqueror, but Midori is certainly usable. It is renders most websites perfectly, and even works with Gmail.
Well its that time again, the Ubuntu community is just about ready to launch another fantastic release and with that release the worlds interweb tubes are going to get clogged as everyone upgrades. It’s about this time that I always start thinking about ways to be more efficient with my bandwidth.
Early results in a study that aims to track open source installations in business has seen Ubuntu and Firefox race to the top of the charts.
The Ubuntu team is pleased to announce the Release Candidate for Ubuntu 8.04 LTS (Long-Term Support) on desktop and server. Codenamed “Hardy Heron”, 8.04 LTS continues Ubuntu’s proud tradition of integrating the latest and greatest open source technologies into a high-quality, easy-to-use Linux distribution.
We are leaving for a short vacation week, I’ve been begged not to leave my laptops at home. Here are the reasons why:
Previously I’ve written about Gimmie, a desktop organizer and panel for GNOME designed to allow easy interaction with the things you use on your computer. Some of it’s developers have forked the project, and created Mayanna. It’s a young project, so I had to compile from source to try it out. Here’s a look at Mayanna revision 23, read on to the end of the post if you are interested in compiling it yourself.
So you just bought an external hard drive for backups. Now, with what filesystem should you format it? Ext2? FAT32? No matter which one you choose, there are trade-offs to consider.
The following guide allows you to wirelessly sync an iPhone with Amarok in Ubuntu 7.10, including adding, editing and playing songs and playlists. Note :- it requires a jailbroken iPhone.
You can stream your music collection to the whole Internet from your favorite Linux distribution. Take some playlist files, add in the functionality of the Icecast server, and you have your own Web-based radio stream. Use it to listen to music remotely on your home machine, or tell your friends and become the next Internet radio phenomenon.
The always popular Ubuntu Open Week returns this month and we welcome everyone from all walks of life, distros, skills, opinions and curiosities to come along and get involved. The aim of the week is to help grow the Ubuntu community, and we have an awesome set of topics ready for you to attend. If you’ve considered getting involved in Ubuntu and don’t know where to start, thent his is a great opportunity to jump in.
The Ubuntu Open Week will take place from Monday, 28 April to Saturday 3 May on #ubuntu-classroom on Freenode.
The next red-letter day for Ubuntu fans will be April 24, when Ubuntu 8.04 LTS (Long Term Support) arrives. Mark Shuttleworth, the CEO of Canonical, the company behind Ubuntu, guarantees that the next version of the popular Linux distribution will make it on time, with something for enterprise, desktop, and Internet users.
This tutorial will show how you can export and import a set of GPG keys from one computer to another. This way, you can sign/encrypt the same way one different computer.
It can be annoying how the GIMP image editor’s image and toolbox windows are separate, if all of them are hidden behind another window you have to bring not only the image to the front but also the toolboxes. This could work much more productively, why not show all the toolboxes whenever a image is in the foreground?
This tutorial describes how to install Ubuntu by copying the contents of the installation CD to an USB memory stick (aka flash drive) and making the stick bootable. This is handy for machines like ultra portable notebooks that do not have a CD drive but can boot from USB media.
Desktop on Demand (DOD) is the latest contender to give users a full-fledged remote desktop instead of Web-based applications to help users to stay productive when they are on the move. Similar to Ulteo (which we reviewed not long ago), DOD gives you a full-blown remote Linux-based desktop -- but that's where the similarity ends. Unlike Ulteo, which is based on the VNC protocol and runs entirely in the browser using a Java-based applet, DOD employs the NoMachine NX technology for accessing the remote desktop.
Everybody, who tried to configure an iptables firewall knows, that it can be quite a PITA. firehol is a tool that helps us to configure iptables according to our needs. In this How-To, I will discribe how to set up an iptables firewal using firehol that only allows SSH and ICMP (the protocol responsible for ping and traceroute). Also, only incoming connections are filtered, and outgoing connections are allowed.
Last month we posted a great idea “Make Your Own Plug ‘N Play Zone Using Ubuntu Linux!“, discussing and introducing the concept of a “zone” where laptop (or other) users could plug their units into and have Linux automatically installed upon boot up.
The Ubuntu Desktop Training program, aimed at new users, is now available. The training provides simulations, practical exercises and information to make daily tasks easy. While prior experience with Linux is not required, basic computer skills are a pre-requisite.
