It is difficult to exaggerate just what a sea change has taken place in the discussion of renewable energy in recent years.
Oldsters like me remember when the idea that (unsubsidized) renewable energy would be able to compete directly with fossil fuels was downright utopian. As late as the early 2000s, people were debating whether it would happen this century, or at all.
But the extraordinary progress of renewables in the past two decades has moved that hoped-for future closer and closer. And now, unbelievably, it is right on our doorstep.
It’s one thing for advocates or energy analysts to say that, of course. It’s something else to hear it coming out of the mouths of energy executives. But these days, residents of the C-suite are discussing renewable energy in terms that would have made hippies blush a decade ago.
In the end, the man who reportedly smeared feces on the walls of his lodgings, mistreated his kitten, and variously blamed the ills of the world on feminists and bespectacled Jewish writers was pulled from the Ecuadorian embassy looking every inch like a powdered-sugar Saddam Hussein plucked straight from his spider hole. The only camera crew to record this pivotal event belonged to Ruptly, a Berlin-based streaming-online-video service, which is a wholly owned subsidiary of RT, the Russian government’s English-language news channel and the former distributor of Julian Assange’s short-lived chat show.
RT’s tagline is “Question more,” and indeed, one might inquire how it came to pass that the spin-off of a Kremlin propaganda organ and now registered foreign agent in the United States first arrived on the scene. Its camera recorded a team of London’s Metropolitan Police dragging Assange from his Knightsbridge cupboard as he burbled about resistance and toted a worn copy of Gore Vidal’s History of the National Security State.
More evidence that our reliance on cars is killing us.
If you want to be as healthy as possible, there are no treadmills or weight machines required. Don’t just take my word for it—look to the longest-lived people in the world for proof.
People in the world’s Blue Zones—the places around the world with the highest life expectancy—don’t pump iron, run marathons or join gyms.
Instead, they live in environments that constantly nudge them into moving without even thinking about it. This means that they grow gardens, walk throughout the day, and minimize mechanical conveniences for house and yard work.
In fact, Blue Zones researchers determined that routine natural movement is one of the most impactful ways to increase your life span, and a common habit among the world’s longest-lived populations.
By steamrolling local taxi operations in cities all over the world and cultivating cheerleaders in the business press and among Silicon Valley libertarians, Uber has managed to create an image of inevitability and invincibility. But the company just posted another quarter of jaw-dropping losses — this time over $1 billion, after $4.5 billion of losses in 2017. How much is hype and how much is real?
A thought-provoking piece on what’s killing San Francisco.
It’s not what celebrants want to hear when the champagne is exploding out of shaken bottles of Dom, the confetti is falling, and their stock is up 8.7 percent at the market’s close, but I have an announcement to make: San Francisco is past its prime and the fires of creation have abated.
With all the millionaires newly minted by Lyft’s IPO, and with those set to be minted by Uber’s and Palantir’s and AirBnB’s, you might expect this enclave to become the next Babylon of American capitalism. While our moralists in the media — Nellie Bowles, Emily Chang, et al. — busily tsk-tsk the greed and the lust and the hypocrisy and the hubris, there is a story here they miss: The city’s current concentration of wealth likely doesn’t represent the beginning of a golden-if-sinful era, but the end.
Teenagers like to take long showers. They can easily spend 20 minutes in there, idling away their time as well as the family’s hot water. I’d done a few rounds of knocking on the bathroom door. I’d even taped photos of baby Arctic seals on the door to remind the kids of the consequences. Didn’t seem to get the point across.
When one night came where one of the kids drained the hot water from our tank I knew desperate measures were needed. I threatened to switch out the nice Delta showerhead with a miserly spray one, guaranteed to save water at the price of a miserable shower experience. Certainly that would get the point across but I knew I’d soon have to swap it out. You know, the Geneva Convention and all.
I began to ponder how a proper geek might solve the problem. I am a Site Reliability Engineer in my day job and I love gathering metrics on the computers I wrangle. What if there were a way to track my kids’ use of water? Wouldn’t it be great to show them how much water their showers actually use? I began to dream up a product I could create that would do just that but then some clever Googling showed me one was already out there: the Water Hawk.
I joined up with a Facebook group called Rivendell Open Source Radio Automation Users as a place to trade tips on using Rivendell. A question that comes up frequently is how Rivendell can be run in the cloud. Since I’ve been doing this for eight years or so I have a pretty good understanding of the challenges. I’ve mentioned some of it before but thought I’d go into more detail of my current setup.
I’m running Rivendell 2.19.2, the current version, and presently I’m not actually running it in the cloud though I could easily change this in a few moments. The magic that makes this happen is containerization. I have created my own Docker instance which installs everything I need. This container can be fired up virtually anywhere and it will just work.
Here’s a summery of my setup. In my container, I install CentOS 7. Then I pull in Rivendell from Paravel’s repos with a “yum install rivendell” command. Rivendell needs the JACK audio subsystem to run so I install Jack2 from the CentOS repos, too. To this I add darkice as an encoder, JackEQ for some graphical faders/mixers, a LADSPA-based amplifier module to boost gain, and of course Icecast2 to send the stream to the world.
Now, one of the problems with a CentOS-based setup is that CentOS tends to have fewer of the cool audio tools than distributions like Debian and Ubuntu have. These Debian-based distros are not officially supported with Paravel packages so you either have to hunt for your own Rivendell dpkgs or you build your own. I’ve found a few of these dpkgs mentioned on the Rivendell Developer’s mailing list but I’ve not had the time to make sure they’re up to date and meet my personal needs. Thus, for my personal setup you’ll find a few parts which I have compiled myself, rather than install from a package. A project for me to take on in my Copious Free Time is to create an entirely repo-based Docker container but I’m not there yet.
Rivendell needs a MySQL/MariaDB database to store its data. I rely on a non-containerized instance of MariaDB in my setup because I already use the database for other projects and didn’t want to create an instance solely for Rivendell.
So here’s how it all works.
My plumber has a beach house. Just saying.
Toren Reesman knew from a young age that he and his brothers were expected to attend college and obtain a high level degree. As the children of a radiologist—a profession that requires 12 years of schooling—his father made clear what he wanted for his boys: “Keep your grades up, get into a good college, get a good degree,” as Reesman recalls it. Of the four Reesman children, one brother has followed this path so far, going to school for dentistry. Reesman attempted to meet this expectation as well. He enrolled in college after graduating high school. With his good grades, he got into West Virginia University—but he began his freshman year with dread. He had spent his summers in high school working for his pastor at a custom cabinetry company. He looked forward each year to honing his woodworking skills and took joy in creating beautiful things. Schooling did not excite him in the same way. After his first year of college he decided not to return.
He says pursuing custom woodworking as his lifelong trade was disappointing to his father, but Reesman stood firm in his decision, and became a cabinetmaker. He says his father is now proud and supportive, but breaking with family expectations in order to pursue his passion was a difficult choice for Reesman—one that many young people are facing in the changing job market.
Interesting analysis of Russian reaction to SpaceX’s successful docking and return of it’s CrewDragon spacecraft.
One of the big questions surrounding the first launch of SpaceX’s Crew Dragon spacecraft was how the Russians would react. They have held considerable sway in the International Space Station partnership by controlling access to the orbiting laboratory since the 2011 retirement of NASA’s Space Shuttle. So far, the Russian response has been one of throwing small bits of shade here and there but trying not to be too obvious about it.
On Sunday, when SpaceX’s Dragon spacecraft docked with the International Space Station, the Russian space corporation sequestered cosmonaut Oleg Kononenko in the Russian segment of the station. This was, Roscosmos said, so that Kononenko could take emergency action in case the Dragon became uncontrollable and crashed into the space station.
After the successful docking, Roscosmos tweeted a Russian language congratulation to NASA, but underscored the fact “that flight safety must be above reproach.” An hour later it published a rare tweet in English, sending “its sincere compliments to the colleagues from NASA,” but without the emphasis on vehicle safety. Neither tweet mentioned SpaceX. (Later, Roscosmos said NASA ordered the ship and, therefore, deserved the congratulations.)
China’s refusal to accept American recycling could lead to a drastic change in consumer habits. Perhaps we will finally have a discussion about our throwaway society.
For decades, we were sending the bulk of our recycling to China—tons and tons of it, sent over on ships to be made into goods such as shoes and bags and new plastic products. But last year, the country restricted imports of certain recyclables, including mixed paper—magazines, office paper, junk mail—and most plastics. Waste-management companies across the country are telling towns, cities, and counties that there is no longer a market for their recycling. These municipalities have two choices: pay much higher rates to get rid of recycling, or throw it all away.
