+Arfon Smith on the shape of open source, excellent analysis of open source projects and activity as they grow in size
At its core, open source is about collaboration. Whether it's version control, licenses, or issue trackers—everything exists to support people working with each other. Open source embodies a model ...

Read about the integrated histogram, opacity and color transfer function editor in Tomviz, and how it is integrated with the application to make it easier and more intuitive to work with your tomographic data

A summary of some of the tools I use for #OpenSource #CrossPlatform development on the desktop, along with some of the things I tried along the way. Things have changed a lot over the years, check it out over on +Opensource.com 
Marcus Hanwell shares his experience with different cross-platform development methods and tools.

A great article. I must admit I went through much the same experiences. CMake was a major key to getting people to write cross-platform applications. Once they could do this and also use Qt for the GUIs the Windows and Linux silos in the workplace disappeared and people could develop on whatever platform they liked. Git was a bonus here.

Today we geek out, checking out the space shuttle at the Air and Space Museum Annex, before continuing further north

Cool! It is pretty impressive. I've only been able to make it there once myself. Traffic in and around this area can be a bear

A great report from John Oliver on scientific studies, and how they are reported in the mainstream media. He is in fine form with everything from open science and replication studies to TED talks and morning shows

Stuck on a plane at BWI, waiting for a pilot, reading about my home country and the seeming #Brexit win, it is not looking good is it...

No it's not good at all. I think Britain will face a lot of economic hardship as a result. I have just watched "Children of Men" I hope it is not prophetic.

John Oliver nails it again with his discussion of the upcoming vote on whether Britain should exit the EU, and British people's general feelings towards the EU (or at least mine to some extent). I think Britain should remain, but there is a part of me that just wants to tell them to ^&*% off :-) Not safe for work - quite a lot of emotion/swearing...

Nevertheless, I watched that one and I have to say, he made an excellent case for staying. I don't understand all the nuances myself, but it does seem like the costs of leaving outweigh the benefits at this point.

Our collaborator +Robert Hovden, along with a number of other scientists, published a number of 3D nanomaterial tomography data sets. This features visualization of the data using Tomviz which is itself an open source project for 3D nanomaterial tomography.

Great to see this data released in a way the whole community can benefit from, I hope to see more if this in the future!
Electron tomography in materials science has flourished with the demand to characterize nanoscale materials in three dimensions (3D). Access to experimental data is vital for developing and validating reconstruction methods that improve resolution and reduce radiation dose requirements.

Great article from +Jono Bacon on avoiding burnout and living a happier life. You are no good to anyone if you burnout, and I have certainly been guilty of not taking sufficient time to stay fit and healthy. I would argue it can be even tougher when you find yourself working on things you are very passionate about too.

Throwing young children, travel and work into the mix makes the balancing act tougher! Loving my new Fitbit, and having those charts show me how inactive I have been really helps increase my discipline.
Recognizing you are getting burned out is half the battle. The next step is to stop burn out in its tracks and take care of yourself.

It's bad enough that the courts have ruled APIs can be copyrighted, if they can't be used under the "fair use" doctrine, we'll be throwing out the last 30-years of software development progress.
The courts ruled that APIs can be copyrighted. That was bad. Now, if APIs can’t be used with fair use, that will be even worse.

Story
Tagline
Physicist, chemist, scientific visualization technical leader at Kitware.
Introduction
I work at Kitware, where my job involves developing open source, cross platform scientific visualization, pre and post processing code (mainly in C++, OpenGL, Qt) for scientific visualization. Strong believer in open science, open data and open source and proud member of Blue Obelisk. Everything posted is my opinion (may or may not coincide with my company, significant other, animal guide, etc).

I work on Open Chemistry software, such as Avogadro as well as other open source toolkits and applications VTK, ParaView, CMakeKDE and several other open source projects. My Ph.D. and degree are both in physics, with a large component of materials engineering. Working hard to improve the quality and openness of open source scientific software, specifically chemistry related software such as Avogadro and 2D charting/plotting in VTK.

Favourite quotations:

"Only two things are infinite, the universe and human stupidity, and I'm not sure about the former." Albert Einstein.

“I believe the simplest explanation is, there is no God. No one created the universe and no one directs our fate. This leads me to a profound realization that there probably is no heaven and no afterlife either. We have this one life to appreciate the grand design of the universe and for that, I am extremely grateful.” Stephen Hawking.

I don't understand why people go here, wouldn't return, the staff were not ice enough but the service was slow, the food was not very good, and I wouldn't return there
