Every few years, I turn an analytical eye on my hobbies, assessing the lifecycle of the materials I use, the sources of inefficiency, and, most importantly, how the practice of the craft aligns with or deviates from my personal environmental ethic. In other words, I do a sustainability audit on my recreational activities. For the last year, I’ve focused on understanding and improving the environmental impacts of my woodworking.
The day they arrived, atmospheric CO2 held steady at 1600 parts per million and the coin traded at #75,236,808.
The coin had surged in the years after the Majority War, when a single miner locked down enough processing power to strip the supply cap from the Core. The Battle for Hard Fork was the bloodiest day in the long history of cryptocurrency. But we won, and the minority nodes now burn endlessly, hashing memes in obscurity while we determined the financial future of the human race.
At least, that’s what I thought.
I awoke in a haze. Still a little drunk from the night before. Sweating in the heat of from the midnight sun. Greenland-3 was the largest mining campus in the Northern Hemisphere and we knew how to keep the evenings lively. Once again, my past self had betrayed my present by signing me up for first shift.
I crawled down the shaft into the main hub and checked my servers. Everything looked fine. A few GPUs were burned but we had plenty to spare. They were older and power hungry, anyway. The new batch would get us twice the hashes per joule.
I grabbed a few GPUs off the rack and climbed down into the bowels of the machine.
It was hot. Hotter than it should be for 15:15 Beijing time. Someone, somewhere, is having a very good day. I crawled through the server racks, scanning for the dead cards. They were clustered, in the back corner, on the same control board. Must’ve been a local surge.
As I swapped out the old cards, I felt someone behind me. I turned, expecting one of the techs from last shift on their way out.
Sea turtles, in case you didn’t know, are pretty great. These giant marine reptiles have been chilling out in the ocean for over 100 million years, largely unchanged. But their evolutionary foray onto land along with the rest of the tetrapods (a move largely regarded as a mistake by most extant species) left them with one one critical vulnerability: they have to return to land to lay their eggs, and their hatchlings must survive a grueling march to the sea within minutes of emerging into the world.
To find their way back to the sea, sea turtle hatchlings emerge from their nests in the darkness and track light cues on the horizon, tracking the glow of starlight on waves. This becomes a huge problem when the beach is littered with the pollution of artificial lights, leading hatchlings away from the sea and towards streets, resorts, and beachfront bars. Light pollution is such a serious problem for sea turtle survival, that many municipalities which host turtle nesting beaches ban the use of superfluous lighting during nesting season.
Even with the intense research focus of the last twenty years, the deep sea is still almost entirely unexplored. New species are par for the course every time a fresh sample is recovered from the abyssal plain. The vast biodiversity of the deep seafloor is offset by a biomass deficit; the denizens of the deep sea, with a few notable exceptions, are few and far between, their size often limited by the paucity of food available to them. While giants like the Japanese King Crab or the Giant Deep-sea Isopod do occur, the vast majority of deep-sea species are relatively small.
The discovery of new species in the deep ocean is common, but the discovery of new giants in the deep sea is extremely rare.
In Japan, slickheads are commonly called sekitori iwashi–’massive sardines’. In recognition of its immense size, the researchers gave this most massive of massive sardines the common name yokozuna iwashi, after the title given to champion sumo wrestlers.
When I began working with Jake Levenson (Oceans Forward) early the year before, we were developing a marine conservation and robotics program to bring to students on the Island, but the storm changed everything. Though my first trip to Dominica was far different from what we had planned, it was the beginning of a long partnership with Levenson, the Dominica Sea Turtle Conservation Organization, and friends and colleagues from Dominica and around the world committed to marine conservation and answering the big question: can a small island create a model for financially sustainable marine conservation that is resilient to both the changing climate and the ever-shifting winds of ecotourism?
From that question, and over many conversations with stakeholders, experts, funders, and community leaders, the Rosalie Conservation Center–a center of learning and research as well as a fish hatchery and a rum distillery–was born.
But some folks want a little extra edge, a little something that dramatically improves how you look in the camera while teaching your class, giving a talk, or holding a meeting. And not just because of vanity. The better and clearer your camera image, the easier it is for your audience to see and understand you (though vanity is a perfectly fine reason too, we have all spent far too much time this year staring at ourselves in the little Zoom box).
You could buy a ring light to provide the best possible light source for looking good on a webcam, but why buy something when you can spend several hours soldering and coding your own custom, addressable, RGBW ring light.
The good nerds at Southern Fried Science are here for you. I spent the last month polishing up my coding, soldering, design, and 3D-printing skills to bring you a 3D-printed, DIY ring light that you can build and code yourself.
Is it cheaper than a commercial ring light? No.
Does it work better than a ring light designed and manufactured by a professional team of engineers? Also no.
Can you independently control each color channel so it looks like you’re in the Matrix, under water, of cosplaying the This Is Fine dog via a large, bulky box that sits on you desk? Yes.
Does it come with a panic button that lets you bail out of Zoom calls by pretending that you’re being pulled over by the police? You better believe it does.
From a global pandemic to information overload to out-of-control drug prices, 1995’s Johnny Mnemonic made a lot of bold predictions about 2021 that landed a bit too hard. Among the hits that landed hardest? The rise of containerized housing and a chaotic kludge of weird construction welded together in a way that doesn’t exactly scream stability and permanence.
The year is 2021. Can we put to rest the idea that a shipping container home is anything but an aesthetic choice?
In forty-eight hours, and amidst the largest peacetime deployment of a military force in any nation’s capitol, President Joe Biden will be sworn in as the 46th President of the United States of America. Biden will inherit a civil service bureaucracy that has been deconstructed by the twice-impeached President Trump. To build back a federal government that has been decimated and demoralized, President-Elect Biden has begun rolling out nominees for critical agencies throughout the federal government. And though these appointments have been met will enthusiasm from the environmental and scientific community, a nagging question lingers among America’s Ocean Stakeholders:
Donald F. Trump hates sharks. We learned that in 2013, when, during an entirely uncontroversial discussion about shark conservation foundations on Twitter, the would-be President of the United States of America blocked a small cohort of marine scientists.
Gracing David Shiffman and myself with a timeline blissfully free of his insufferable Tweets for eight years was the only good thing he has ever done for the ocean.
Initially, it appeared as though Trump’s war on the oceans would take a backseat to his other social, judicial, and environmental atrocities. Though a troubling selection for a host of reasons, Wilbur Ross’s appointment as Secretary of Commerce was seen as a relatively non-threatening move. His letter to NOAA staff, reassuring them that his department would continue to follow best-available science, was met with praise. His initial leadership appointments received bipartisan support.
It is clear now in hindsight, that that initial optimism was intensely naïve.
This is the winter of finding as many good, educational projects to keep our kids as occupied as possible. If you’re anything like me, you probably have a stack of assorted electronics in various stages of disrepair, which is great for your hardware hacking dads and moms, but kids need projects with a little more structure and, especially for the younger ones, a lot less soldering.
All of these projects were built with the help of my kiddo (age four), require no soldering or electronics skills to start, involve just enough coding to stay interesting, and use Adafruit’s CircuitPython ecosystem, which is fairly easy to learn. Adafruit does a great job compiling detailed instruction for every project. These can all be completed in a lazy afternoon.
