New Video Published: Using the IPython Library

Showmedo is proud to publish:[1406] Using the IPython Library, a video-tutorial by unpingco This video is part of the series Visual Parallel Computing Using Python-based VISION/HPC

This segment discusses the MEC and MECXLocal nodes in the IPython library to quickly prototype a parallel computation without having a prior connection to a backend cluster.

Visual Parallel Computing Using Python-based VISION/HPC

We may not know much about the future of computer programming, but one thing we do know is that it is parallel and the biggest challenge facing software programmers and hardware designers is how to exploit all those multiple cores out there.

So Unpingco’s new Python series is both fascinating and prescient. Oh and useful [...]

Photo-editing with GIMP

Rede’s wondeful series shows how to repair old photographs with the GIMP graphic-editor. Check it out even if you haven’t got any old photographs to repair – you’ll learn a whole lot of GIMP anyway. And the photos are lovely too

`[1399] Enhance A Framed Photo With GIMP Part 1‘, a video-tutorial by Rede, [...]

More C++ video-tutorials

Yiroel’s huge C++ beginners set continues to grow. This is a fantastic resource for starting programmers in what is a notoriously tricky language. Compared to a scripting language like Python, C++ makes much greater demands on the programmer, with a much more complex syntax and work-flow. So if you could do with a bit of [...]

OpenOffice 3.1 Writer Tutorial

Do you want to learn OpenOffice Writer?  OOo Writer is the open-source world’s answer to Microsoft Word – it is pretty much feature compatible in every respect, it works the same way and you can edit and share .doc files just as if you were using Word.  You can even open older .doc files that [...]

Scientific and Parallel Computing Using IPython

Wearing my research-scientist’s hat I can honestly assert that Python’s strength in scientific programming is one of its glories, and maybe less appreciated than it should be. That makes series like unpingo’s
Scientific and parallel computing using IPython pure gold for its target audience. Combining the power and flexibility of the enhanced IPython interpreter with some [...]

Boa-Constructor (WxPython GUI-builder) Video Series

There are precious few open-source (OS) GUI builders of any repute but the lack is sorely felt in the WxPython world. WxGlade is a fine tool  if you like, as I do, it’s minimalist approach, but it is best for fairly small projects. When programming in the C++ WxWidgets I was impressed by the DialogBlocks [...]

A Sting in the Tale

I just caught a very cool example of what some people are doing with javascript these days. A little molecule-builder, it’s impressive and fun at the same time:

check out Molecools

Now that was fun, and note the example molecule, Ethanol. As an aside, the simulator is pretty crude so there’s no valency-counting or any of the [...]

Python 3 Videos

In a trickle sure to become a flood, we are starting to receive some videos demonstrating Python 3 and its differences from the 2.3–2.6 family. Exciting time for all Pythonistas, but it will take a while before Py3k is the first Python of choice. But watch these and the others to come if you want [...]

A Special Mention

Erik Thompson continues his huge series ‘Developing Emol’ which follows his creation of a 3D molecule viewer using Python and WxPython, the Python GUI-building library. Erik has really created something special here, and it’s my own personal favourite Showmedo series. He covers quite comprehansively the creation of a useful and very cool piece of software. [...]

New Videorama

Things are starting to settle with the new site and new-server teething problems, so some new video announcements are long overdue. I’ll deal here with the non-python contributions:

First up we have atlef’s videos, showing how to perform a minimal Ubuntu install.
Neil Dickenson continues his justifiably popular and really rather wonderful Introduction to Assembley Language.
Steve’s extends [...]

UK Government Turns To Open Source

Given the UK government’s historic love of all software solutions proprietary,  the news that Open Source solutions are now to be actively sought for and encouraged is significant indeed.  Possible reasons for this volt-face are the collapse of more than a few high profile proprietary IT projects and a general need for belt-tightening as the [...]
