Please be sure to place the aspect of Linux being discussed in the SUBJECT LINE.
Discussions will work as follows: Post a question or comment on software or technique here and it will be directed to a blog forum under that topic. This will allow this blog to serve as a primary index. All are invited to post descriptions of useful software here.

I use 4k Video Downloader. Available for all OS flavors. This is terrific software. Certified by Microsoft and Apple. Freeware for Linux.

GIMP is somewhat equivalent to Adobe Photoshop. I have found that I can do almost everything I did with Photoshop with respectable results using GIMP. GIMP is open source freeware and works with Windows and Linux. Download here.

Yes GIMP absolutely rocks. Also Blender for 3D stuff is freakin AMAZING (bit of a learning curve tho). Kdenlive is pretty darn good video editor too. You can cause all sorts of trouble with that little trio.

Cinelerra is the most complex and powerful and difficult video editing program in Linux. I first set it up in Centos 5.0, then later in Ubuntu. It is roughly equivalent to Adobe Premier or Final Cut Pro. It requires two or three computers to approach professional levels - the primary cpu, the manager and the video server. I am really attracted to the idea of making my next film with Cinelera. If you get serious with Cinelerra and need a video server, PM me.

Blender is a 3D video drawing program somewhat equivalent to Lightwave. It is open source freeware and multi-platform (Linux and Windows). It is unbelievable. Look at some of the demos on their website for an idea of its power. Incredible.

Blender? Did you guys say ... Blender?!?

Here's a Blender animation I made to demonstrate Bill Cummings' technique for flipping a hang glider that's upside down in water:

Here's one of my early wings (before I added wires):

This is one of my 3 "pitch, roll, and yaw" axis animations (from one year ago yesterday):

And this is the result of some code I've written to build tree-like objects for importing into Blender:

Here's my best kingposted glider so far:

In fact, I even wrote a Blender Addon to generate hang gliding wings. You can see some of the output images here in our "mock voting" topic:

I'm hoping we can use Blender (and other tools like Gimp) to make a really great on-line hang gliding training manual.

We've got a start in the US Hawks Training Manual topic here:

Rick,

Your "Linux for Hawks" Blog is such a great idea that I'd like to create a whole new sub-forum for it right beside the Training Manual Forum. That way you (and everyone else) can organize topics relating to technology in one place.

How does "Technology for Hawks" sound to you?

I would move your "Linux for Hawks" topic in there and we could start others like "Gimp for Hawks", "Blender for Hawks", etc.

Please let me know if that's OK with you.

Bob

I think the title should be around Linux and this is why. Linux tends to attract independent thinkers and the number of Linux users here is way out of proportion. There is a philosophy centered around open source freeware that is attractive to this group and that is that these tools shouldn't be held for ransom. There is also a belief and hope that open source will advance faster as more people participate and these already excellent applications will become more and more powerful.

Also Wall Street and journalism co-opted the term "technology" to mean computer technology. That offended a lot of us who preferred the English language. Technology is the use of tools. That's too broad a subject, these days.

I like the rest. Liked the animations, too.
