Image manipulation in GNU/Linux has always been associated with The Gimp. However, most users will find Gimp vastly oversized for their needs. Fotoxx is a neat, simple and yet very advanced photo manipulation software that is definitely worth installing and playing with.
quickplot is a fast, interactive 2-D plotter. All it needs to do its job is a text file with x and y points in a list. If those points are longitude and latitude in decimal degrees, quickplot works like a simple GIS program, with some surprising capabilities.
This article explains how I set up quickplot to do species mapping for Australia. For most of my mapping work I use qgis and Google Maps/Earth, but quickplot is handy for quickly making simple maps and zooming in on details. With an executable size of only 453 kb, quickplot is the tiniest and fastest GIS I know.
In a previous article on syncing and restoring your GMail account with the excellent GMVault I voiced one minor and perhaps unfair criticism. Namely, that as backed up e-mails had no recognizable titles, it was virtually impossible to identify specific messages. But, of course, that was never the intended purpose of GMVault. It would have been the icing on the cake if it was.
Backing up all your precious data and settings is a given. However, when it comes to e-mail we tend to develop amnesia. It's the ghost at the banquet, yet losing your e-mails, your address book and contacts (especially if you run a business) would be a catastrophe. Fail to backup at your peril. Of course, if you use a desktop client like Evolution of Thunderbird, configuring either of them with IMAP will do the trick for you but if you prefer the traditional web interface for Gmail, then you need a different solution. GMVault may be that solution.
Yes, you read that correctly. If you've ever wanted to put together a bespoke PDF document and then edit it to add or delete features, you don't really need to hunt for some specialist software to get the job done. Wikipedia is only a URL away and LibreOffice comes bundled with all the major distros--and if not it can usually be installed from the repositories.
Spare a thought for old time stalwarts like Konqueror. Many great features have been stripped out but it's still a a great file manager (and a decent browser) even if Dolphin has been promoted as the default file manager of the KDE desktop. Back in the day, Konqueror was able to handle lots of media without having to open a separate application. I want some of that functionality back for those times when I just want to view it quick and fast without all the bells and whistles--and the good news is that it's not difficult to do.
I love Mozilla Thunderbird. I love using it with IMAP which lets me synchronize with GMail. To make the experience complete, I also like to view my RSS feeds. Setting them up is shamefully easy. There's no excuse not to try it, so let's do it.
First, we need to set up an account so select
Other Accounts from the
File > New drop-down menu to initiate the Account Wizard. There are three choices. Accept the default for Blogs and Newsfeeds.
All desktops are created equal; however, some desktops are created more equal than others. LXDE, Gnome, Unity and KDE are brimming with menus but Fluxbox is Spartan by comparison. Great for speed on older, slower machines but I still use on my latest dual core, 3GB memory laptop. I want that speed but I also want a better choice of applications in the Fluxbox menus. In short, all the speed without sacrificing the power. That's the problem. Fluxbox Editor is the solution.
A picture paints a thousand words, so here's why you need it.
Think "installing software in distros like Debian and Ubuntu", and you think automatically of Synaptic,
apt-get on the command line or the new kid on the block, Unbuntu Software Centre. Sometimes, you just overlook the obvious. Did you know that you can also install and remove software using the KDE System Settings Menu? Thought not. Me neither, until I accidentally stumbled upon it--and I wasn't even in the KDE desktop at the time. I was using the LXDE desktop when I spotted it in the Preferences section of the Start menu. Curious? Me too. Let's take a look.
Whenever the The Electornic Frontier Foundation (EFF) commends Ubuntu for "retrofitting operating systems to support privacy against local attackers" as a worthy objective, I'm inclined to sit up and take notice. Since Ubuntu Precise Pangolin (12.04) these privacy setting have been integrated out of the box as a feature in the System Settings menu. It's called Activity Log Manager (previously Zeitgeist Global Privacy), a GUI frontend to partially control Zeitgeist. It's what powers Ubuntu's Dash in the Unity desktop. Here's how to use it to control what the Gnome activity log is recording.
When it comes to file managers, Linux users are spoiled for choice. But that doesn't stop developers from building tools for juggling files. Take Sunflower, for example. This file browser is built for speed, and it will appeal to fans of the twin-panel interface. Indeed, Sunflower's unobtrusive and lightweight interface allows you to manage files with consummate ease. Although Sunflower is designed to play nicely with the Gnome desktop environment, the file manager doesn't look out of place on other desktops, including KDE.
The most used graphic program in the free software jungle is Gimp. It is a hugely powerful piece of software, but when all you want to do is to crop a JPEG image without any loss of quality, it's positive overkill: that's when you need CropGUI.
In my entomological work I often need to compare two images of bugs side-by-side.
Comparisons are surprisingly hard to do with either of the image viewers I normally use, namely Eye of Gnome and Ristretto. First I open two instances of the viewer and adjust their window sizes and positions for easy side-by-side comparison. I then open one image in one viewer window, and the other image in the other window. If I want to zoom in or out, or pan across the images, I have to do this independently in each viewer window. If I don't save this two-instance arrangement on a dedicated workspace using 'Save session on exit', I'll have to repeat the setting-up next time.
Comparisons are much simpler in Geeqie image viewer, which is now in most of the Linux distribution repositories. I first heard about Geeqie in 2011 when it was featured in a glowing online review. I hope this article adds to the glow.
I like tea. Well, I'm British. I've just discovered a new brand that I've never seen before. You can't dunk it in a cup of boiling water but it has some powerful features. This article explores two of the best.
Tea is a text editor. It's available in the Ubuntu repositories. If you're using another distro, try Tea's homepage. Text editors are ten a penny but Tea is different. When you first start it, you'll notice that the view mode is controlled by built in vertically-stacked tabs.
There's been a lot of noise on the internet recently about the fact that the Windows-based software being used in the remote control system of drones use by the American military has been hit by a virus and this has caused the Department of Defense (DOD) to use GNU/Linux which is a more secure option. This has, predictably, caused raised eyebrows and demands by some that any military organisation should be prevented from using GNU/Linux in offensive weapons systems.
The GNU/Linux ecosystem is blessed with many tools to clone a hard drive image which can be used to reinstall your Debian-based distro in an emergency or duplicate on another machine, but sometimes you might want to do a clean install of Ubuntu on another machine and then add in the extra software you installed in the original distro. For that you need a combination of Synaptic, the GUI frontend for
apt-get and a little command line magic.
There is no shortage of backup software in GNU/Linux. From full clones of hard drives to browser bookmarks there's something for everyone. However, sometimes you just need to be more selective about what you backup.
If you want to backup your precious desktop settings, you should try Ubuntu Tweak: it is bundled with a host of really useful features, it's been around for a while and it's up to version seven. You might find a version in your distro's repositories but if you're out of luck, download it from the official site.
Last week I finally took the leap and did an online upgrade from Ubuntu 11.10 to 12.04 (Precise Pangolin). To my relief it was a flawless operation and one of the things I wanted to experiment with the much hyped HUD feature which is being slated as a replacement/supplement to application menus. It's a Marmite feature. You either love it or loathe it but what caught my attention was the keybinding used to launch it and how this interacts with its "near neighbours".
People like Dolphins. They're fast and smart and swimming with them is on many people's "ten things to do before you die" list. Not me though. The nearest I'll ever get to a Dolphin is the one sitting on my laptop -- the Dolphin file manager that is. It's nippy too but I find that I can speed it up even more by using keybaord shortcuts.
One of the first things that newcomers to GNU/Linux learn to do is to bypass big Start menus and blank screens (like Fluxbox) and use
ALT+F2 to launch an application by simply typing in its name. Every desktop ecosystem has its own way of implementing this feature and I was pleasantly surprised, after a long absense from the KDE desktop, to see how it could be used to do some really clever things. Here's five of them.
