After a recent post on a forum, extolling the virtues of a number of  free Open Source program, I made mention that they were always the same problems being mentioned – OpenOffice, ClamWin, Audacity, etc. SourceForge alone holds over 150,000 Open Source projects, let alone those at Google Code, etc.

So, I was set a challenge – find some Open Source software that most people won’t have come across.

Ok, that was the plan. Now, the limitations (self set). Nothing too technical, nor niche. No games (otherwise I could just easily provide a vast list of them). Oh, and they have to be Windows applications – no Linux, Mac, PHP scripts, etc.

I thought plunging into my Firefox bookmarks would yeald many but, sadly, most were either games or too technical for this list. Or I’ve covered them elsewhere in my blog. So, a number I’ve had to scourer SourceForge for (oh, I wish their search facility was better). And some goodies I’ve come up with too – here’s my 40 (in no particular order)…

TV-Browser
A desktop based EPG. It’s German in origin but includes UK channels. I’ve only had a brief play with it so far, but I’ve been impressed.

MP3Gain
This is something I’ve been using for years. Now, adding gain to MP3s (i.e. bringing them all up to a similar volume) is something built into many media players and burning products. However, MP3Gain is a standalone product designed to do this one task. And well.

DVDStyler
DVDStyler is a DVD authoring program for the creation of professional-looking DVDs. It allows not only burning of video files on DVD that can be played practically on any standalone DVD player, but also creation of own-designed DVD menus.

Arora
Yes, it’s another browser! Based on WebKit (like Chrome and Safari), it’s fast and available on a number of platforms. However, the fact that is has recently “elbowed out” Konqueror as the browser of choice in Kubuntu, has made news.

MuseScore
An excellent WYSIWYG musical score editor. It’s packed full of features, including importing of data and has a built in sequencer and synth.

SmillaEnlarger
Another simple idea, done well. SmillaEnlarger will magnify images in high quality. Useful for “blowing up” part of a photo. And it will go on a USB key as well.

AxCrypt
A file encryption tool that integrates directly into Windows Explorer. Simply right click on a file and you can quickly and easily encrypt it, with password protection (or without, for simple sending via email).

WindowsPager
If you’ve used Linux any time recently, you’ll probably have come across its virtual desktop environment, where you can easily switch between multiple desktops via an icon in the toolbar. Well, WindowsPager provides a similar facility. It’s not perfect, however, and I spotted a problem with Command Prompt windows, but it’s worth a try – as with most of these products, it’s still being worked on.

Synkron
Synkron is a relatively powerful folder synchronisation tool. How you use it, well, is up to you – for something as simple as synchronising a USB key to your PC, or as a quick backup tool.

Hugin
I said I’ve avoid anything too technical and, well, this isn’t. It’s just powerful. But if you’re a keen photographer, you’ll love this. It’s a photo stitcher (which can allow you, for example, to make panoramic images) which is a bit more manual that many (but, hence, it’s power).

PeaZip
PeaZip is an excellent compression program, like WinZip and 7-Zip. It also has file encrytion facilities and a portable version is available. Of course, 7-Zip is also Open Source, but PeaZip does, at least, offer an alternative.

Scribus
Scribus is a desktop publishing tool, similar to Microsoft Publisher. It has an easy to use interface but Scribus also supports professional publishing features, such as CMYK color, separations, Spot Colors, ICC color management and versatile PDF creation.

Appetizer
This is an application launcher which allows organizing your shortcuts and folders into a convenient dock. It supports plugins and skins, so is completely configurable to your own taste.

BonkEnc

RedNotebook
RedNotebook is a graphical diary and journal helping you keep track of notes and thoughts. It includes a calendar navigation, customizable templates, export functionality and word clouds. You can also format, tag and search your entries.

Gminder
Gminder is a simple, but effective, desktop version of Google Calendar. It waits in your system tray and alerts you when you have an upcoming Google Calendar event. GMinder supports multiple calendars and allows you to configure how you want to be alerted. Since it downloads your events, it works offline and enables you to preview your agenda of events. New events can be added to your Google Calendars using a Quick Add feature.

Fwink
This is an excellent webcam application that takes still images from your camera at timed intervals and puts them on your web site with FTP. You can add effects like text messages, time stamps and an overlay image.

PopTray

calibre
Got an eBook? calibre includes library management, format conversion, news feeds to eBook conversion, as well as an eBook reader sync feature and an integrated eBook viewer.

Process Hacker

JavaRa

TweetMyPC
Make use of Twitter in other ways – send commands to your PC, allowing you to shutdown, log off, transfer files, etc.

Xmind

MonitorES
A fabulous idea – when your lock your desktop, MonitorES will automatically put your monitor into standby and, optionally, pause any media players, mute sound and change your Instant Messaging status’.

iColorFolder

Data Crow
Weird name, but useful application. Data Crow is media cataloguing software – audio, software, book, film and photo collections.

winsupermaximise
This is another “simple but handy” utility. It adds a system tray icon which, once clicked (or you can press a hotkey combination), will “super maximise” the current window – that is, it will resize so the title bar is actually above the screen boundaries, thus saving those extra pixels that you don’t want to waste. A great utility for Netbook owners, in particular.

PhotoGrabber
This application makes it easy to download tagged pictures from Facebook. It only takes a few clicks!

Cache My Work
CacheMyWork is a handy utility that enables you to reboot Windows without losing your place in your work. It builds a checklist of currently open applications, and will restart the apps you’ve selected the next time you logon to the computer.

HKTunes
HKTunes (formerly iHK) allows you to control iTunes using global hotkeys. For example, you could change the track and music volume while playing a game. It has a tray menu and a GUI to let you select hotkeys.

Synergy+

It’s intended for users with multiple computers, where each system uses its own display. It’s a little like having a 2nd or a 3rd desktop…
