> why do you think germany pushes for labelling gas as green

What makes you think I don’t know? ;)

> as long as france imports electricity we shouldnt be able to say it is green

Sure, the current system of certificates is a complete joke and utterly unfit for purpose (you can sell “green electricity” in the middle of winter if you also buy a document showing that the same amount was produced last summer in any other EU country). Under the current system it is mostly irrelevant because certificates are cheap. Hopefully the rules will be tightened in the next couple of months and then the green labelling will be a bit more meaningful (and electricity produced from coal in September won’t be “green” anymore).

> especially when we see our nuclear reactors aging and being phased out.

I think the French government realised at some point the shitshow it would be. They started walking back earlier promises about plant closures and words I’ve heard say that the life extensions won’t be a political problem. Now, new builds will be the problem of the next government. Please vote responsibly…

low level officials taking bribes means you can do stuff like never wear a seatbelt, just pay the cop $20 USD if you get pulled over. get pulled up for smoking indoors? $20 USD. run over an illegal immigrant and kill them? USD 1000 to have their records completely erased. Sim card? $5 USD cash. rape? what? the police here hung up on my friend on a 911 call because they spoke english and not the 'national language' (police do speak english here).on a different note, it is legal to rape your wife here

low level corruption causes immense problems and injustices in society. here, everyone drink drives. driving a car while extremely drunk here is default behaviour.

ye high level official bribery will cause probelms, but the low level stuff is what completely craters the system and causes the catastrophic failures in complex engineering systems.

I have some older family friends that frequently go mushroom picking. I went with them one day and had a great time. We spent the afternoon walking through a beautiful forest enjoying the weather, bonding, and collecting mushrooms. We then went home and they cooked up a tasty meal with the mushrooms from the day.

It reminded me of going out fishing with my father, where we'd spend the day on the lake just talking and tossing some lines in the water. Every once in a while we'd catch a fish, occasionally there would be some excitement and we'd catch a large or unusual fish, and then we'd go home and fry them up for the family. Sure, we could have went to the grocery store and bought a few fillets, but that was never the point of the day out in the first place.
Taubes interview on Peter Attia's podcast is fascinating. He starts by laying out his career in journalism bringing light to scientific malpractice and otherwise very sharp minds totally deluding themselves when they get stuck on a pet hypothesis. The second half of the podcast was about his later career where he took on sugar. He then illustrates all of the self delusion and poor scientific thinking he had just described. It's kind of amazing.

Very cool. I looked back at the 2020 finalists, and the first video from that list truly boggled me: https://youtu.be/5DYeAkx2IBo. At around 16s in, my vision of the stair case suddenly and completely changes to being upside-down to rightside-up. I know what's going on physically, but it feels like my brain is doing these behind-the-scene calculations and at a certain moment feeds my conscious mind a brand new image. Pretty neat how some optical illusions can put you at odds with your own brain.

quick edit: It doesn't always happen for me when I let the video continue to play, but if I pause it at 16s, then as soon as I hit the pause button, the image completely flips for me. Pretty wild. I think it's probably because I let my eyes drift away from the staircase for a brief moment, and when they return the image is sort of reinterpreted.

With Seat Belts & Driving rules we still have 45,000 Driving related deaths a year in the US. We don't ban automobiles because that number isn't 0.

Seatbelts and vaccine's are high impact & low-cost. The same cannot be said about every possible driving or covid restriction. Closing schools has a real cost, sending kid's home from school for a week every time they have a fever has a real cost, requiring kids to wear masks for 8 hours a day has a real cost.
As a brief summary, I spend a couple hours every day working through a textbook. In choosing what/how to study in mathematics I'm driven by two considerations: 1. It's important to master the basics before anything else. So I need to cover linear algebra (done) and calculus (WIP) 2. Beyond the basics, I'm driven by curiosity/play. My current interests lie mostly in stats and physics.

Happy to chat otherwise, I put my email in my profile.
All European airlines I've been on always required then up for takeoff and landing
For several years now, I've been an advocate for either "uninstalling" the default route on (most) hosts and/or switching to a default deny policy for outbound traffic, just like we all did for inbound traffic a long time ago.

I'll readily admit that the amount of work required in order to do this is HUGE and, of course, it isn't gonna happen overnight. Every time we have another one of these massive vulnerabilities that affects damn near everything and everybody, though, I think we get just a little bit closer.

Once some large company makes the decision to do it, then actually does it, then (at some point down the road) shares publicly how it totally saved their ass when $thing happened, maybe some CISOs will start to take notice and (eventually) follow suit.

As with IPv6, I remain hopeful that we'll get there at some point in my lifetime! Unfortunately, though, I'm sure it'll take a lot more "bad shit" happening first.
Ask HN: Which successful startups use 'no code'?
It's claimed that with no code, you can:

This is about 100x faster than traditional approaches, which take around 1,000 hours [2]

If 'no code' really produces production grade software so rapidly, we should expect to find some successful startups using no code -- where are they? (i.e. can we name some?)

My great hope in these cold war-esque times of tension between China, Russia, and the US is that the field of battle becomes competition in Great Achievements for science, engineering, and space exploration.

Permanent human-staffed moonbases are a good goal to strive towards.
Yup, battery improvements may neutralize power-to-gas --- though there's a lot of reasons to consider it as useful (in addition to gas-to-power there's a whole lot of users of natural gas and not all may be easily retrofitted).

Still, I think a share of decent, predictable base load makes everything easier, and that's where nuclear can shine.
unique_ptr has zero overhead except when passing or returning by move. But I don't find myself doing that anywhere performance matters.

The overhead is not inherent, but is rather a consequence of C ABI choices inherited into C++ calling conventions. It is, though, real, and not easily fixed. E.g., RISC-V's ABI binding peobably suffers from the same overhead, not for any good reason, but just because the RISC-V crowd couldn't spare the attention to fix it.
Altimeters are only pilot calibrated to ensure planes travelling in various directions can trust their vertical separation is constant even amid rising or dropping temperatures and pressures. In that context an altimeter that calibrates itself is quite undesirable

There is the radio-altimeter which uses ground based radar but that is for spoken-aloud altitude readouts and terrain warnings and as far as I’m aware doesn’t factor in Boeing or airbus autopilot.

At least in the U.K., the lingo has us refer to this always as height (ie, above the ground) and not altitude (within the air above a hypothetical sea level)

> Radioactive waste generated from treating highly contaminated water used to cool crippled reactors at the Fukushima No. 1 nuclear power plant has thrown up yet new nightmarish challenges in decommissioning the facility, a project that is supposed to be completed in 30 years but which looks increasingly doubtful.

So not only did their nuclear engineers fail to foresee the effects of the tsunami, they are still being caught out by unexpected problems a decade later. It seems that nuclear energy is just beyond the ability of even well organised societies to safely manage.

the plane acting funny on landing in jakarta, sort of jumping around, weird turbulence

when it land, he look outside and see that one of the major aileron has fuselage completely missing and had been replace with electrical tape

the plane was flying funny because one of the aileron was replaced with electrical tape from dollar store by international airline technician

importantly, if this plane crash, nobody will ever admit this, cctv record deleted, etc. they will just blame beooing

I would reckon (based on my own observation, combined with some research that has come out recently -- see below) that "a good percentage of this good percentage" probably failed due to nervousness, rather than than truly lacking basic coding skills.

If they failed your test -- you just know they failed your test. That doesn't mean you now that they're incompetent.

This reminds me of a story when I was a kid.

Except you usually send the password once, and get back a cookie with a token that you present for the rest of your session (possibly to other endpoints/servers). Whereas with basic auth, the login/password keeps being sent.
But the next crew has been told to configure the system properly many many many times (training, checklists, recurrent training). Telling them once more won’t achieve anything. On the other hand, telling previous crews not to set it wrong might achieve something, removing one failure mode and adding another level of redundancy.

The ghastly Helios accident [1] was also triggered by a misconfiguration (by maintenance staff). Sure, you’ll tell the pilots again to actually run their checklists, but you’ll also tell the maintenance crew not to screw up the standard settings.

Counterpoint: if you have a checklist item, and it is always in the desired/expected configuration already, you might start to skip it (with the concomitant consequences if one day it isn’t).

Maybe flight crews/maintenance staff should configure the machine randomly after a flight/maintenance, so as to force the next crew to actually run the checklist carefully?

Social media has basically turned the world into a sort of bizarre mob rule situation when it comes to unpopular opinion.

I think that we have a responsibility to speak out on matters we believe in and ignore negative pushback.

The alternative is that anyone can shut down a viewpoint by simply flooding the opposite side. You don't know whether a poster is a troll, a real person that's simply misguided, or a real person that posts in good faith.

You don't even end up with what's merely emotionally satisfying - that would be bad enough - but with the set of events or opinion that wins out purely based on competition.

Anything with electronics is going to be orders of magnitude more expensive than insecticide treated nets, which cost cents. https://malariajournal.biomedcentral.com/articles/10.1186/s1... is one of a number of studies measuring the efficacy. To compete in the quest to end malaria it needs to be cheaper per-capita, off-grid, and at least as effective. I think nets, mosquito or parasite eradication and vaccination are the only approaches anyone is seriously pursuing.

I do wonder, how significant are inefficiencies in transmission, charging, and storage?

Although hopefully cars are more efficient

Are cylindrical reflector telescopes with software focus correction possible?
One of the most expensive and difficult to launch parts of the James Webb space telescope is the mirror. Parabolic mirrors are hard to produce and hard to assemble into larger reflectors with a single focal point.

Cylindrical mirrors, on the other hand, are easier to produce (can use a reciprocating polishing tool with a 2D parabolic profile). However, they can't produce a point focus as per this: https://physics.stackexchange.com/questions/29853/are-cylindrical-mirror-telescopes-possible

Isn't image processing at a level of advancement now where we can place a linear array of sensors at the focal area of a cylindrical reflector and correct the optical aberrations in software? Can't we launch an entire array of such reflectors stacked on top of each other (similar to Starlink) and use a much simpler unfurling process in space to create larger, cheaper space telescopes?

Right now nuclear is the only green energy that is suitable for base load generation apart from hydro, and it takes a long time to build new nuclear plants, so I’m okay with a bridge solution that dramatically reduces emissions even if it doesn’t bring them to zero. The alternative is a dependency on much less green fossil fuel plants when the sun doesn’t shine and the wind doesn’t blow.

Intelligent people shouldn’t quibble over an imaginary “green” line, but we should focus on minimizing emissions per unit power.

> The article said--it's the smallest plane Emirates flies.

What does that have to do with anything?

The 777 is a huge aircraft. It has a maximum passenger capacity of 550 people.

If you can have 550 people lives in your hands and are making mistakes like this, it doesn't matter if it's the smallest aircraft in their fleet.

And before anyone bothers to point it out, I know this particular airframe was not configured for 550. But being the smallest in the fleet means absolutely nothing.
A small factor more than aircraft in the short term. Zero in the medium term when launch companies vertically integrate propellant production based on renewables. A net positive once we start relying on non-terrestrial resources instead of poising our planet to extract metals and power.

Basic Auth has become increasingly difficult to use as a generic way to protect a web app. Many apps these days have endpoints that respond with 401 when a user isn't logged in, which if you're fronting the application with basic auth, results in the user being "logged out" as the browser thinks the credentials are no longer valid.

The hijacking of HTTP status codes by client-side apps wanting to interpret them in their own way makes me think we need a new range of codes for user-defined statuses.
