Andrew McGill is chronicling the devices and apps he’s creating this summer and invites readers to join him. Are you an inventor and want to share a project? Please drop him a note: firstname.lastname@example.org.
If you live in the Washington, D.C., area, you’re probably familiar with Capital Bikeshare. And if you don’t, I bet the nearest American city might have something like it: A system of public bicycles available for rent, strategically placed throughout town for point-to-point trips. If you have a membership or a credit card, you can check out a bike at a kiosk, ride it to your destination and re-dock it at the nearest Bikeshare station. It’s one of my favorite things about the D.C. area.
But! There are few things more annoying than wrapping up a satisfying ride and pulling into bikeshare dock ... that is completely full.
There are phone apps out there, like Spotcycle, that publish bike station statuses. But pulling out a smartphone in the middle of a ride doesn’t sound particularly safe. This is a perfect app for a smartwatch, however—a quick glance at your wrist could tell you if you’re headed for an empty station or a wall of docked bicycles.
Using data from Capital Bikeshare, I put together a quick app that pulls the user’s location, finds nearby bike stations and lists how many open slots they have. (Technical explanation here, code here.)
Here’s a GIF of the app in action:
I haven’t yet published the app to the Pebble store, but I’ll do that once I add a few more improvements. Nothing in the works for Apple Watches or Android products at this point, but who knows!
It’s never been easier to be a mad scientist. Back in the day, it took so much work: You had to rent a dungeon, fashion your own Tesla coils, and spend half your life reading cracked leather tomes written your equally deprived predecessors.
Not so anymore. Computers are small, fast and cheap, allowing a D.I.Y. types to slap a microprocessor on pretty much anything, and for less than $50. The internet can deliver a tutorial in an instant and any electronic component within a few days. And easy-to-program platforms have made controlling physical objects with code not only possible, but practical.
All this is great for a would-be inventor. Unless, like me, your drive to work on a project (which seemed so strong in the morning!) somehow gives way to an evening of Alias reruns night after night. Life gets in the way.
So here’s my resolution: Following the lead of WNYC journalist James Keefe, I’m resolving to buckle down and make a new thing every week this summer. It’ll ideally be a real thing—something you can see and could hold, not just ephemeral code powering an app. (Though I’m still keeping the ephemeral code door open if I hit a rough patch.) I’ll document what I’m doing through this thread, as well as more technical write-ups on my own blog. So far, I’ve built a smartwatch app that searches for nearby public bicycles and a silent doorbell for when my coworkers get locked out of the office.
Are you a time-crunched tinkerer? Please join me this summer by sharing your projects: email@example.com. What have you built in the past? What are you working on now? And what should I build next?
The GOP has become, in form if not in content, the Communist Party of the Soviet Union of the late 1970s.
We are living in a time of bad metaphors. Everything is fascism, or socialism; Hitler’s Germany, or Stalin’s Soviet Union. Republicans, especially, want their followers to believe that America is on the verge of a dramatic time, a moment of great conflict such as 1968—or perhaps, even worse, 1860. (The drama is the point, of course. No one ever says, “We’re living through 1955.”)
Ironically, the GOP is indeed replicating another political party in another time, but not as the heroes they imagine themselves to be. The Republican Party has become, in form if not in content, the Communist Party of the Soviet Union of the late 1970s.
I can already hear the howls about invidious comparisons. I do not mean that modern American Republicans are communists. Rather, I mean that the Republicans have entered their own kind of end-stage Bolshevism, as members of a party that is now exhausted by its failures, cynical about its own ideology, authoritarian by reflex, controlled as a personality cult by a failing old man, and looking for new adventures to rejuvenate its fortunes.
A guide to America’s awkward, semi-vaccinated months
The past 11 months have been a crash course in a million concepts that you probably wish you knew a whole lot less about. Particle filtration. Ventilation. Epidemiological variables. And, perhaps above all else, interdependence. In forming quarantine bubbles, in donning protective gear just to buy groceries, in boiling our days down to only our most essential interactions, people around the world have been shown exactly how linked their lives and health are. Now, as COVID-19 vaccines rewrite the rules of pandemic life once more, we are due for a new lesson in how each person’s well-being is inextricably tangled with others’.
This odd (and hopefully brief) chapter in which some Americans are fully vaccinated, but not enough of us to shield the wider population against the coronavirus’s spread, brings with it a whole new set of practical and ethical questions. If I’m vaccinated, can I travel freely? Can two vaccinated people from different households eat lunch together? If your parents are vaccinated but you’re not, can you see them inside? What if only one of them got both shots? What if one of them is a nurse on a COVID-19 ward?
After saying a racial slur and being exiled from radio, Morgan Wallen has become only more popular. What’s going on?
It’s no exaggeration to say that one of the biggest artists in American music right now is a disgrace. Three weeks after the 27-year-old country singer Morgan Wallen said a racial slur on camera, his second studio album, Dangerous: The Double Album, is at No. 1 on the Billboard 200 chart. His singles have been bobbing in the country-music top 10 and the cross-genre Hot 100. Billboard’s ranking of the most popular artists in the United States had him in the top spot for five straight weeks. Thousands of people are, at this moment, streaming Wallen’s songs, buying his records, and watching his music videos—putting money in the pockets of someone who has admitted to saying one of the most noxious things imaginable.
The first way to fight a new virus would once have been opening the windows.
A few years ago, when I still had confidence in our modern ability to fight viruses, I pored over a photo essay of the 1918 flu pandemic. How quaint, I remember thinking, as I looked at people bundled up for outdoor classes and court and church. How primitive their technology, those nurses in gauze masks. How little did I know.
I felt secure, foolishly, in our 100 additional years of innovation. But it would soon become clear that our full-body hazmat suits and negative-pressure rooms and HEPA filters mattered little to Americans who couldn’t find N95 masks. In our quest for perfect solutions, we’d forgotten an extremely obvious and simple one: fresh air. A colleague joked, at one point, that things would have gone better in the pandemic if we still believed in miasma theory.
Financial confessionals reveal that income inequality and geographic inequality have normalized absurd spending patterns.
The hypothetical couple were making $350,000 a year and just getting by, their income “barely” qualifying them as middle-class. Their budget, posted in September, showed how they “survived” in a city like San Francisco, spending more than $50,000 a year on child care and preschool, nearly $50,000 a year on their mortgage, and hefty amounts on vacations, entertainment, and a weekly date night—even as they saved for retirement and college in tax-advantaged accounts.
The internet, being the internet, responded with some combination of howling, baying, pitchfork-jostling, and scoffing. Representative Alexandria Ocasio-Cortez of New York quipped that the thing the family was struggling with was math. Gabriel Zucman, a leading scholar of wealth and inequality, described the budget as laughable, while noting that it showed how much money consumption taxes could raise.
Biology textbooks tell us that lichens are alliances between two organisms—a fungus and an alga. They are wrong.
In 1995, if you had told Toby Spribille that he’d eventually overthrow a scientific idea that’s been the stuff of textbooks for 150 years, he would have laughed at you. Back then, his life seemed constrained to a very different path. He was raised in a Montana trailer park, and homeschooled by what he now describes as a “fundamentalist cult.” At a young age, he fell in love with science, but had no way of feeding that love. He longed to break away from his roots and get a proper education.
At 19, he got a job at a local forestry service. Within a few years, he had earned enough to leave home. His meager savings and nonexistent grades meant that no American university would take him, so Spribille looked to Europe.
The virus can take many paths to reinvading a person’s body. Most of them shouldn’t scare us.
On its face, reinfection appears to be a straightforward term. It is literally “infection, again”—a recovered person’s second dalliance with the same microbe. Long written into the scientific literature of infectious disease, it is a familiar word, innocuous enough: a microbial echo, an immunological encore act.
But thanks to the pandemic, reinfection has become a semantic and scientific mess.
Newly saddled with the baggage of COVID-19, reinfection has taken on a more terrifying aspect, raising the specter of never-ending cycles of disease. It has sat at the center of debates over testing, immunity, and vaccines; its meaning muddled by ominous headlines, it has become wildly misunderstood. When I ask immunologists about reinfection in the context of the coronavirus, many sigh.
An uncertain spring, an amazing summer, a cautious fall and winter, and then, finally, relief.
Updated at 10:12 a.m. ET on February 24, 2021.
The end of the coronavirus pandemic is on the horizon at last, but the timeline for actually getting there feels like it shifts daily, with updates about viral variants, vaccine logistics, and other important variables seeming to push back the finish line or scoot it forward. When will we be able to finally live our lives again?
Pandemics are hard to predict accurately, but we have enough information to make some confident guesses. A useful way to think about what’s ahead is to go season by season. In short: Life this spring will not be substantially different from the past year; summer could, miraculously, be close to normal; and next fall and winter could bring either continued improvement or a moderate backslide, followed by a near-certain return to something like pre-pandemic life.
In his response to an adverse decision by the Supreme Court, the former president previewed an argument he’s likely to keep using.
Former President Donald Trump faces various legal and political challenges, but few seem to have gotten him as agitated as a routine, expected, unsigned decision by the Supreme Court on Monday.
Trump had already lost a bid to prevent Manhattan District Attorney Cy Vance Jr. from acquiring his financial records via subpoena. The former president then sought a stay while he searched for other means to stall. As anticipated, the justices rejected the request. Trump then issued one of just a handful of public statements he’s issued since leaving office, blasting “the Continuing Political Persecution of President Donald J. Trump.”
His vehemence is part of a long-running pattern: Trump dislikes all investigations, but nothing rattles him like probes into his finances. (When he tried to fire Special Counsel Robert Mueller, it was because of a report that Mueller had subpoenaed his financial records.) We can guess at the reasons. First, Trump is extremely defensive about anything that might imply he is not as rich as he claims. Second, there is much to suggest that Trump might have committed financial crimes.
Side effects are just a sign that protection is kicking in as it should.
At about 2 a.m. on Thursday morning, I woke to find my husband shivering beside me. For hours, he had been tossing in bed, exhausted but unable to sleep, nursing chills, a fever, and an agonizingly sore left arm. His teeth chattered. His forehead was freckled with sweat. And as I lay next to him, cinching blanket after blanket around his arms, I felt an immense sense of relief. All this misery was a sign that the immune cells in his body had been riled up by the second shot of a COVID-19 vaccine, and were well on their way to guarding him from future disease.
Side effects are a natural part of the vaccination process, as my colleague Sarah Zhang has written. Not everyone will experience them. But the two COVID-19 vaccines cleared for emergency use in the United States, made by Pfizer/BioNTech and Moderna, already have reputations for raising the hackles of the immune system: In both companies’clinical trials, at least a third of the volunteers ended up with symptoms such as headaches and fatigue; fevers like my husband’s were less common.
