Gnome 3 includes support for themes, but does not include a convenient way to select them. The Gnome Shell Theme Selector Extension by Finnbarr P. Murphy provides a simple way to change themes from the Activities screen. read more...

Changing resolutions in Android x86

Up

Down

Chances are, if you are installing Android onto a desktop system, you will want to make use of the higher resolutions that are available, since your desktop probably has a bigger monitor than the average mobile phone or tablet. Android is quite flexible in the resolutions it offers, and most Android apps can take advantage of higher resolutions.

Install FB4Linux in Eclipse

Up
vote
Down

Flash development in Linux is often left to a generic text editor used with the free Flex SDK. It is certainly possible to code this way, but you do lose out on a lot of the functionality of a more specific IDE. The FB4Linux project provides a plugin for Eclipse that provides a similar environment to FlashBuilder 4. The only downside is that the installation instructions gloss over a few of the details required to get the plugin installed in Eclipse 3.5.2, which is the version of Eclipse that is available in the Ubuntu software repositories at the time of writing. This article shows you how to get FB4Linux up and running from start to finish. read more...

Placing system icons on the top bar in Gnome 3

Up
vote
Down

"System Tray" icons were a great idea in Windows 95, but over the years the concept has been abused. It's not uncommon to get a new Windows PC with a dozen system tray icons, usually serving no purpose other than to advertise the existance of the application to which the icon belongs.

Linux machines are not quite as bad, but this hasn't stopped the designers of Gnome 3 from hiding these icons in a hidden bottom bar that appears only when you move the mouse to the bottom of the screen.

If you still prefer to have these icons on the screen (and lets face it, the Gnome 3 top bar is mostly empty space anyway), you can use the icon manager extension to selectively move icons from the bottom bar to the top bar. read more...

Installing Android x86 in VirtualBox

Up

Down

In a previous post I showed you how to install and configure the Android SDK emulator to boot up quickly. What you may have found out by now is that the emulator is incredibly slow. In fact it is only any good if you have the kind of PC that can render the entire Transformers movie in a few minutes.

If you are just interested in running Android applications on your desktop PC, a project called Android x86 provides a copy of the Android operating system compiled for x86 processors. The latest release is Android 2.2, which is a little bit behind Honeycomb (Android 3), but is still capable of running almost all Android applications. read more...

Boot C64 games in Linux

It's lunch time, and you have 5 minutes to chill out and forget about those reports due by the end of the week. You could play some solitaire, but why limit yourself to the same old dull card games? Some of my favorite games were made for the Commodare 64, and to this day still provide a quick and enjoyable distraction for those otherwise dull desk based lunch breaks.

The good news is that don't have to remember a bunch of archaic commands to get your favorite C64 games up and running. Using the VICE emulator, it takes nothing more than creating a desktop icon to boot a C64 game. read more...

Using an ISA Proxy server in Linux

Up
vote
Down

NTLM (NT LAN Manager) is a Microsoft authentication protocol. It is used extensively in older versions of Windows, and Microsoft has embedded the NTLM authentication into several communication protocols, such as HTTP, POP3 and SMTP. One benefit of NTLM authentication is that Windows users can get transparent access through an ISA proxy server. While the proxy does require a username and password, IE will happily send the users current credentials without any additional prompt.

Linux users don't tend to be so lucky. Most web browsers will support NTLM authentication when using an ISA proxy, but there are some cases, like when using the proxy settings in OpenSuse 11.2, where the lack of support for NTLM can effectively prevent internet access.

Fortunately there is a fairly simple way around this limitation. A small Python utility called NTLM Authorization Proxy Server can be used to ferry internet traffic between the OS and a ISA proxy server. read more...

beesu: Fedora graphical front end for su

Up
vote
Down

Anyone who runs Linux regularly will know the sudo or su commands well. The first will let you run commands and applications with root privileges, while still retaining the more common environment variables like $HOME. The benefit of sudo is that you only need to supply your own password, and not the root password. The su command does much the same thing, except that it requires the root password. The su – command will drop you into shell that has all of roots environment variable set.

These commands are great, but they have to be run from the terminal. So what if you want to run a file browser or something similar with root permissions? Traditionally the gksu application provided a GUI front end to su, but a decision was made quite some time ago not to include this with Fedora. read more...

Run Android apps on Linux: Boot the emulator quickly

Up

One of the great things about Android is the fact that anyone is free to develop applications for the platform. Google provide Android SDKs for Windows, Linux and MacOS, and part of the SDK is an emulator that lets you run the latest Android operating system from your PC desktop. The aim here is obvisouly to allow developers to test their applications without having to swap to an actual Android device, but it can also be used to run your favourite Android based applications alongside your traditional desktop apps. read more...

JPC2: A point and click Windows XP virtual machine

Up
vote
Down

I've said it before, and I'll say it again. Linux has come a long way, but there are inevitably one or two Windows only programs that you just can't replace with open source equivalents. For me it was the CHM compiler, and FlashDevelop. Sometimes it's not even a case of being able to find an open source replacement if you are trying to document or grab screen shots of a Windows application.

Wine may offer some relief, but virtualization is the most reliable solution. However, both have traditionally involved a lot of configuration. But now there is a solution that goes by the name JPC-2. It is a pure Java virtual machine that can run unmodified versions of Windows XP and older copies of Ubuntu. read more...

A system monitor applet for Gnome 3

Up
vote
Down

One of the controversial decisions made by the Gnome 3 developers was to do away with applets. For the most part I agree that applets were not very useful, but one applet I did use was the system monitor. To be able to see at a glance if the cpu or memory was being overloaded was a great convenience, and one that is sorely missed in Gnome 3.

The good news is that this new system monitor extension from paradoxxxzero brings back most of the functionality of the old Gnome 2 system monitor applet. read more...

Create native looking Firefox web apps

Up
vote
Down

HTML5 and Flash have been used to great effect in recreating traditional desktop apps that can be run through your web browser. Google is so confident that web apps can replace your desktop apps that it has released the ChromeOS, which is not much more than the Chrome web browser presented as a desktop operating system.

Firefox has long supported running web apps in a kind of desktop mode through projects like Prism, WebRunner and Chromeless. But a lot of these projects are either dead, in their early stages, or require a lot of mucking around to get running.

The good news is that it is quite easy to launch your favourite web apps in a chromeless Firefox 4/5 window with just a few simple steps. read more...

Why Flash, HTML5 and ChromeOS are good for Linux

Up
vote
Down

So, given that the vast majority of users don't actually use an OS as anything more than a launchpad for their word processors, IM clients, games and web browsers, why has Linux failed to make any real impression in the desktop OS space? The problem, in a nut shell, is that the word processors, IM clients and games they use in Windows don't run in Linux. Linux has failed on the desktop because it can't be used to launch the applications everyday users are familiar with (and I don't count Wine or its various commercial incarnations as suitable for everyday users). This is where technologies like Flash, HTML5 and ChromeOS and GeckoOS, and to a lesser extent the variety of tablets that are available today, are starting to level the playing field. read more...
