letitbeirie··on B773 at Paris on Apr 5th, airplane did not respond to commands
It's not just Korean pilots though, deference to a KLM captain in the wrong was a critical link in the chain of events that led to the Tenerife disaster.
letitbeirie··on Why I'm in the Army Reserve – an explainer for my friends in tech
> This isn't a positive

It's a silver lining. It's shameful that the need exists at all, but it's definitely a positive for the people who are getting mostly screwed by the status quo but would otherwise be getting completely screwed.

Or a gas station.

Their margins are outrageous but only if they can get you to come inside - they're only making a cent or two off each gallon of gas they sell.

> Americans seem to want and even feel they're owed that kind of false sincerity/kindness from "low skill" workers they interact with

This is true to a sometimes weird degree, but...

> there's no indication that the same business that owns the bar is the same business that owns the building

A business is going to get judged on its physical space regardless of ownership or fairness.

There's a bar in Amsterdam with a rather unique tap collection and a remarkably annoying location, but every time I mentioned it to one of my friends there neither of those things would come up - it was always some variation of "oh isn't that the one where you have to walk up a sketchy spiral staircase to use the toilet?"

letitbeirie··on Justice Department Issues Web Accessibility Guidance Under the ADA
Accessibility and building regs ironically combined to prevent a bookstore where I used to work from replacing a set of skinny, awkward, inward-opening doors which made the entire store a fire trap.

Why? Because state law required that any part of the building being modified be brought into compliance with modern building code. In this case:

- Replacing the doors with outward-opening doors would mean bringing the doorframe into compliance by widening it

- Widening the doorframe would mean widening the alcove into which it opens, and in a 19th-century masonry mid-rise every wall is structural

- Widening the door also means widening the short (3-4 steps) staircase leading up to it and bringing them into code by making them less steep

- Making the stairs less steep means they are now longer than the alcove and protrude beyond the property line onto the sidewalk

letitbeirie··on Light mode, Dark mode, and Gen-Z mode?
Just to add to the confusion there's also "Xennial" which is pronounced exactly the same way but refers to people ~15 years older.
letitbeirie··on Light mode, Dark mode, and Gen-Z mode?
> late-1990s / early-2000s eclecticism like old Geocities.

My first thought seeing the Gen-Z version was "why don't they show a flashing marquee banner, an email with flapping wings, and play some MIDI music while they're at it?"

letitbeirie··on How a small nuclear war would transform the entire planet (2020)
Hundreds of warheads would do the trick but it wouldn't take more than a two-week power outage to bring most civilizations currently on earth to the brink of collapse.
letitbeirie··on 200-foot-long railway to nowhere is a brilliant shipping loophole
Hawaii (the island) can and does, but most of Hawaii (the state)'s electric demand is on Oahu where they haven't found any geothermal that's viable for making power.

letitbeirie··on 200-foot-long railway to nowhere is a brilliant shipping loophole
Solar is already so prevalent on Oahu that they have grid frequency excursions that would be unimaginable on the mainland.

Once grid-scale energy storage gets cheaper Hawaii will have one of the cleanest energy grids on Earth. Until then they have to complement their solar production with peaker turbines that typically burn diesel.

letitbeirie··on Toyota suspends domestic factory operations after suspected cyber attack
If a car factory is making 1000 cars a day, a 30-day supply is all the parts needed to make 30,000 cars. Managing that is a giant, complicated, land-consuming operation unto itself, and it all has to get sorted before you can build car #1.
letitbeirie··on Ask HN: Is Reddit Becoming Dumber?
Subs that celebrate other forms of tribalism seem to avoid politics pretty well.

Places where you see everyone rally around comments like "save that for r/politics. this is where we come to talk about how much the EAGLES suck, not the president."

Point of clarification: you are allowed to take it back so long as you don't commit any other crimes while doing so.

As OJ Simpson can readily attest, you are not allowed to rob it back.

I can't see a device that displays graphics between a person's eyes and any feature of an industrial plant being very popular with said industrial plant's lawyers.

letitbeirie··on US DOE to offer $6B to keep struggling nuclear reactors online
Greenpeace's take on nuclear power [1]:

> Nuclear power is dirty, dangerous and expensive. Say no to new nukes. > > Nuclear energy has no place in a safe, clean, sustainable future. Nuclear energy is both expensive and dangerous, and just because nuclear pollution is invisible doesn’t mean it’s clean. Renewable energy is better for the environment, the economy, and doesn’t come with the risk of a nuclear meltdown.

The Sierra Club's [2]:

> The Sierra Club continues to oppose construction of any new commercial nuclear fission power plants. Further, the Sierra Club supports the systematic reduction of society's dependence on nuclear fission as a source of electric power and recommends a phased closure and decommissioning of operating commercial nuclear fission electric power reactors.

Each month my ISP sends me a flyer telling me how much easier it would be to pay them if I let them auto-draft their fee out of my bank account.

Each month I tell them what I think of that idea by sending them another check.

Most things "simple living" - working with your hands, living off the land, camping, etc. - are only enjoyable if they're optional.

letitbeirie··on Tesla recalls 26,681 U.S. vehicles over windshield defrosting software
It can be in some cars, but with sporty 6-speeds in particular it can be very difficult to tell if you're in reverse or 1st just by looking because the shift gates are so narrow. My VW is even worse, because you get it into reverse by pushing the shift knob down and then basically shifting into 1st.

Of course not knowing which gear you're in when you start the car is less a problem with a manual - interacting with the gear lever is a much more normal and automatic (irony) part of the driving experience so if you start rolling the wrong way you just pop it into a different gear and move on with your life.

Most manual transmissions don't give you any indication whether you're in reverse or the gear next door until you start moving.
letitbeirie··on Gen Z Kids Don't Understand How File Systems Work
> especially with search getting so good

This is kind of the crux of it here. The reason this is a "Gen Z thing" is because you really couldn't get away with just using search until relatively recently.

I don't know of anyone my age (gen x/millennial) who even thinks to use Windows search because it was so tragically useless for so long.

letitbeirie··on Mergers ruin everything
Spectrum is kind of a weird case though because it kind of has to be monopolistic - if you allow multiple, independent systems to share the same frequency band, none of them will work.

> Suppose instead they held a new auction every year or every month for use of the spectrum in a given region until the next auction.

This would work if the government or some common third party were responsible for putting up towers (and lease them to the telecoms like MVNOs), but as it is the telecoms build and operate the towers themselves, and the hardware loadout changes slightly depending on which frequency bands that telecom is allowed to use.

letitbeirie··on Tesla drivers report a surge in ‘phantom braking’
It's for safety reasons so that the system doesn't enter an undefined state if one of those sensors fails, which it eventually will.

If the signal goes from "black nothing" to "orange round" you know you went from no object to an orange, but what if your form sensor breaks and it goes from "black nothing" to "orange nothing?"

letitbeirie··on Tesla drivers report a surge in ‘phantom braking’
> A new car built by my company leaves somewhere traveling at 60 mph. The rear differential locks up. The car crashes and burns with everyone trapped inside. Now, should we initiate a recall? Take the number of vehicles in the field, A, multiply by the probable rate of failure, B, multiply by the average out-of-court settlement, C. A times B times C equals X. If X is less than the cost of a recall, we don't do one.
letitbeirie··on Tesla drivers report a surge in ‘phantom braking’
You're still left with the two-sensor problem though: if lidar says "pedestrian" but vision says "clear," you don't know if it's a false positive in lidar or a false negative in vision.

If your safety reaction is consequence-free, no problem. If it isn't (like slamming on brakes in traffic), you really want a 3rd sensor so you can do 2oo3 voting.

letitbeirie··on Anti-work subreddit goes private after rough Fox News interview
> In the future, anti-work in the style of "where's my robot that does all work I don't freely choose to do"

Maybe someday. This was one of the common optimistic promises of the space age (along with "power too cheap to meter") that the 70s smothered like a wet blanket.

letitbeirie··on Avoiding Fallback in Distributed Systems (2020)
> physical systems, say a spaceship, which require critical capabilities and operational regimes, and ask if fallback fault management is really a 'bad idea'.

Depends on context obviously but IME as a controls engineer, what you want is a failsafe, not a fallback.

AWS calls a fallback when you "use a different mechanism to achieve the same result." Failsafes are all about returning the system to a stable and controllable state - if you can salvage the result that's great, but if it takes flaring off $10,000,000 worth of distillate to stabilize the system that's fine too.
