Big list of open-source MacOS apps

Serhii Londar (Patreon) maintains a list of open-source applications available for MacOS. Unlike some similar guides, it's exhaustive rather than curated, and easy to reference in a single, well-organized HTML page.

List of awesome open source applications for macOS. This list contains a lot of native, and cross-platform apps. The main goal of this repository is to find free open source apps and start contributing. Feel free to contribute to the list, any suggestions are welcome!

I found out about Screentendo, which turns your screen into a Mario level. Read the rest

3D printing stethoscopes, tourniquets and crucial dialysis-machine parts in Gaza

Picture of an open-source tourniquet by the Glia Project

Tarek Loubani is a Palestinian-Canadian doctor who works with the Glia Project, a group that creates open-source designs for 3D-printable medical hardware. Their goal is to let local populations manufacture their own medical wares at prices considerably lower than in the marketplace, and in situations where -- because of distance or war -- it may not even be possible to ship in equipment at any price. Some of their early work has been in blockaded Gaza, for example.

So far, Glia has designed a stethoscope that can be made for about $2.83, and a tourniquet that costs about $7 to make.

But Glia's also developing a project that's even more ambitious, and crazily interesting: An open-source dialysis machine.

In the current issue of Logic magazine (which is amazing front to back, BTW), Loubani talked about how regulatory capture has jacked up the price of dialysis, and how to use open-source to design around it. I'll quote it at length here, because Loubani's description of the problem and the hack is super eloquent:

Dialysis is also an interesting problem of capitalism. A good analogy is disposable razors. Broadly, in Canada, there’s Schick and there’s Gillette. You can’t use a Schick razor on a Gillette handle and vice versa. That’s called vendor lock-in.

Fundamentally, dialysis machines are a pump, a controller, a flow meter, and a little bit of tubing. Nothing special. The only way for companies to make them profitable is to create vendor lock-in and collude with each other.

Open source interface to connect your brain to your computer

Most of us need a computer interface implanted in our brains like we need a hole in our head. That said, there are benefits to bridging the gap between mind and machine. Joel Murphy is the founder of OpenBCI, an inexpensive, and non-invasive, brain-computer interface (BCI) platform. People have used OpenBCI to control robots, compose music by thinking about it, develop games, and help individuals who are "locked in" and can't control their bodies communicate with the outside world. Mark Frauenfelder and I interviewed Joel about open source, DIY neurotech in this episode of For Future Reference, a new podcast from Institute for the Future:

The Optimal Route for Visiting Every U.S. National Park

Optimal US National Parks Road Trip

Randy Olson, a researcher at University of Pennsylvania Institute for Biomedical Informatics, has taken his genetic algorithm previously used to find Waldo, and has applied it U.S. National Parks. In August, the National Parks Service is celebrating their 100th year, and Olson has calculated the optimal route to hit every single park in one monster road trip.

The trip would take 14,498 miles, which is only 9.29 days of pure driving time with no stops and no sleep. A bit longer if you want to see any of the sights.

A great thing about Olson's posts is he open sourced his original code, so you can dig in and make your own route. Plan your own trip and support his patreon if you want to see more work like this. Read the rest

Help ocean scientists build open-source research tools

CTD units are incredibly important to ocean research, measuring three basic factors of sea water — conductivity, temperature, and depth. Almost every major research vessel has one. But the units are part of what ensures that it's expensive to get started doing ocean science. Each one can cost between $5000-$25,000. Now, a group of ocean scientists are trying to finance the design of an open-source CTD that could be built by anyone for less than $200. You can help fund their efforts at Rockethub. Read the rest

Limor "ladyada" Fried profiled by MIT

MIT is rightfully proud of alumna Limor Fried, the superhero hardware hacker behind AdaFruit Industries, creators of fantastic DIY, open source electronics components and kits. We're proud of Limor too! From MIT News:

Apart from selling kits, original devices and providing hundreds of guides online, Adafruit works around the world with schools, teachers, libraries and hackerspaces — community technology labs — to promote STEM education, designing curricula in circuitry and electronics, among other initiatives.

The company has released an online children’s show called “A is for Ampere.” On a weekly Saturday night program, “Ask an Engineer,” anyone can ask Fried questions online or show off their original devices.

One of Fried’s favorite stories, from a young viewer of “Ask an Engineer,” illuminates what she sees as the growing diversity of engineering. “A parent emailed us after watching the show with his daughter,” she says. “I had another engineer on the show with me — my friend Amanda — and this parent’s daughter asked, ‘Dad, are there boy engineers too?’”

LocalWiki Antarctica, a crowdsourced map of the icy southern continent

LocalWiki's Philip Neustrom says,

My non-profit, LocalWiki, has been working on this really incredible project to help document the continent of Antarctica. Most notable, at least right now, is this custom map we've pieced together from very-hard-to-find NASA aerial imagery and coastline datasets. It's probably the most beautiful thing I've ever worked on.

Check out the LocalWiki for Antarctica. The project "aims to document the full extent of human involvement on the continent," and for now is focused on a two-mile region surrounding Palmer Station.

Google lawyer on Oracle victory: "People are treating patents like lottery tickets"

Google defeated Oracle's claims regarding Java in the Android operating system. But at what cost? Google's general council writes: "The case illustrates the cost when the patent system doesn't work well. It costs millions of dollars to invalidate bad patents. That's money we'd rather spend on great new products for people to use." [Ars Technica] Read the rest

Open Goldberg Variations: free, open source recording and modern score of classical masterpiece

Performed by Kimiko Ishizaka on a Bösendorfer 290 Imperial in Berlin's Teldex Studio, there's already plenty to love about a new cut of Bach's Goldberg Variations. But this one is also the first fan-funded, open source, and completely free recording of it.

"Every part of it is free for you to use, share, and copy," said Robert Douglass, who launched the successful Kickstarter project behind Werner Schweer's new version of the classic score and its production.

Schweer's modernized and digitized score was itself created with free and open source software from MuseScore.com.

The producers said their goal was to be "precise to Bach’s instruction, yet full of personality and character".

"To help make this recording truly timeless, we need your help. Share it. Give it away. Introduce others to its beauty, and explain to them why you love it," Douglass wrote. "Make yourself responsible for converting another person to being a Bach fan."

The production's website is at opengoldbergvariations.org. Five double CDs of the recording will be given away to listeners who sign up for a promotion. There's also a facebook page for the project and a twitter account to follow.

Wisconsin Public Radio also developed a website to accompany its broadcast of the Open Goldberg Variations, opengoldberg.wpr.org, which will display the score in real-time so listeners can "see" the music there as it plays: "a first-ever event, proving bleeding edge technologies," says Douglass.

Incredible art made with open-source weather data

This is what the wind over the United States looked like on March 27th, 5:00 pm Eastern Daylight Time. It's beautiful. And it's even better if you go to the project page, where you can watch real-time wind currents move around the map.

The National Digital Forecast Database is a weather forecasting system that provides open access to weather data collected all over the United States. The National Weather Service has field centers all across the country, that collect information about things like wind speed/direction, precipitation, and barometric pressure. They combine this data with big-picture satellite tracking and algorithms that are based on what we know about how weather patterns work, and that's how you get the kind of daily forecast we rely on to plan our days.

In the process, the National Weather Service generates a lot of data—data that has not, traditionally, been accessible to just anybody. We saw the forecasts, but it wasn't as easy to see the measurements the forecasts were based on. The NDFD changes that. It's a really great example of publicly funded research being made available to the people who help provide the funding.

And when that happens, you get cool projects like this one, where data on wind direction and speed are used to create truly amazing art. The information on current conditions, and predictions for the future, are updated hourly. When you look at the animated version of this map, what you see is the most recent forecast playing out.

Scary science, national security, and open-source research

I've been following the story about the scientists who have been working to figure out how H5N1 bird flu might become transmissible from human to human, the controversial research they used to study that question, and the federal recommendations that are now threatening to keep that research under wraps. This is a pretty complicated issue, and I want to take a minute to help you all better understand what's going on, and what it means. It's a story that encompasses not just public health and science ethics, but also some of the debates surrounding free information and the risk/benefit ratio of open-source everything.

H5N1, the famous bird flu, is deadly to humans. Of the 566 people who have contracted this form of influenza, 332 have died. But, so far, the people who have caught bird flu don't seem to have contracted the disease from other humans, or passed it on. Instead, they got it from birds, often farm animals with whom the victims were living in close contact. H5N1 was first identified 14 years ago, and there's never been a documented case of it being passed from person to person.

But that doesn't mean such a leap is impossible.

That's because of how the influenza virus works. Influenza is made up of eight pieces of RNA, containing 10 genes, and they all replicate independently of one another and there's no system for error correction*. That means you have more opportunity for mutations to arise that change what the virus does and who it can infect. Read the rest

MIT and the future of open-source education

MIT has long offered thousands of undergrad and graduate level course materials for free online. This month, they announced plans to significantly update and expand that effort, creating an open-source education system called MITx that will basically allow anyone to virtually take an MIT class, participate in laboratories, and get individual assessment on whether or not they've learned the material. The school even has plans—not fully worked out yet—to offer some kind of certificate of completion to people who take classes this way and can show that they've mastered the subject. MITx will open in spring of 2012. I'm looking forward to checking out this great resource! (Thanks to Chris Hayden!) Read the rest
