No and they shouldn’t be. Leap seconds were never a great idea and they become an increasingly worse idea with every passing year. They are a great example of a standards making decision made without sufficient negative feedback from its implementation costs.

There are lots of great aviation museums in the USA, highly recommend visiting them. Many allow various degrees of access inside the aircraft, even more so if you chat up the museum staff. I don't imagine the boneyards will.

The primary purpose of code review is whatever your organization decides it wants it to be. The post makes a good enough point but undermines it with this dogma.

Good surgeons are a bit like major airline pilots. They have more pricing power than you think.

Highly recommend everyone watch this video https://www.youtube.com/watch?v=KtQ9nt2ZeGM

Briefly, the most important reason an EV is better because it unlocks energy portability. You gain the flexibility to source your energy in many more ways than with a gas car. Oil energy is about as optimized as it's ever going to get. With electricity, we're just getting started.

I don't think CHSRA is a well-run program.

For many years, I observed the San Francisco Caltrain DTX (Downtown Extension, recently rebranded "The Portal"). This is the most important transit missing link in Northern California that is expected to connect two of the highest ridership transit arteries in the Bay Area and eventually unlock single-seat rail transit between Sacramento, San Francisco, San Jose, and points south. DTX is a two-mile tunnel planned to connect the rail line terminus south of San Francisco downtown to Market Street, where the BART subway has the 4 highest ridership train stations in Northern California. The combined project (DTX and Transbay Terminal, the already built train station it's supposed to connect to) is about 15 years late and many billions of dollars over budget.

What struck me is a complete lack of urgency and accountability, combined with out-of-control meddling by politicians pursuing completely unrelated goals. The project spent several years in EIR and initial planning, which is to be expected. Then for over a decade, San Francisco's board of supervisors held the project hostage because they wanted to demolish a freeway south of where the actual project is, while bolting on an unrelated and unrealistic tunneling project (the "Pennsylvania Avenue alignment") and taking over the governance of the Caltrain board (Caltrain is the least dysfunctional transit system in the Bay Area, so the Caltrain board was not too keen on this proposal). Eventually, after wasting many years and tens (hundreds?) of millions of dollars, the balance of power on the BoS shifted and they agreed to stop holding the project hostage, restructure the board (TJPA), and re-hire staff to actually plan the tunnel.

I've seen multiple project managers/directors come and go, and countless community input meetings happen discussing completely hypothetical project concepts. The money set aside for the project from the original Transbay budget is long gone, and numerous funding opportunities have passed by because the TJPA and its stakeholders were not ready to plan and submit a viable proposal in time.

Here are some things I would want to change going forward:

- Transit projects should be centrally planned by the state government (i.e. a regional subdivision of an agency similar to Caltrans) with structured opportunities for resident feedback and authority to override most input from local governments. This should include exemptions from CEQA and other review, and strong eminent domain powers.

- The Caltrans-like agency should have independent regional metro divisions (i.e. Bay Area, LA area, etc) with dedicated sources of regionally collected funding as well as a mandate to own and lease out land adjacent to transit stations as part of its funding. The divisions should have budgets to retain project management staff who accumulate long-term experience and manage multiple projects. They should have the independent authority to issue bonds and be required to publish construction efficiency and ridership statistics.

- Labor unions should be systematically prevented from influencing the course of planning, construction, and project execution. Unions meddle and cause many delays and project complications.

Unfortunately, even a structure like that is not a panacea. If you look at CHSRA, it actually has some of the features that I listed above. When CHSRA was first started, the planning process fell victim to meddling from state legislators (most famously the one who forced the route to go through Palmdale), followed by many wasted years fighting NIMBYs and doing useless planning. Ultimately, the only hope I see is to insulate the planners from political interference, set them up with independent funding, have one agency head who is responsible and accountable, and reduce the veto powers that California grants to citizens and governments.

You don't know much about Seth do you? That's not "AI", it's called a script.

It's nice to have the luxury of deciding which of the horrible choices Ukrainians face are war crimes. But by that measure, a Grad MLRS is just as much of a war crime. Everything in the grid square it obliterates will also be dead.

(For those who don't know, the Grad is the most produced MLRS ever, and the Russian army's weapon of choice for indiscriminately bombarding enemy territory)

Just want to mention how much I appreciate this discussion and the opportunity to learn from it. This is what I come to HN for (nowadays there are also really interesting YouTubers who do informative teardowns of power electronics and other devices, too e.g. Labo de Michel, Watch Wes Work, etc.)

The 777 and 787 programs have never seen a passenger fatality resulting from an engineering defect. That is a monumental achievement in light of the passenger miles served. Boeing has its problems, but that record speaks for itself

I did something similar. I like to keep my phone limited (the only real useful/joyful things on it for me are family pictures, music and maps). So I used an iphone SE until it fell apart, now I use an iphone mini that doesn't have enough storage so it offloads all but the top ten apps I use.

I didn't make it slow and buggy on purpose though. Apple did that for me with Liquid glass. Which I guess works!

Yes. The payments landscape has shifted pretty dramatically in Japan over just the past 3 years. It used to be that you had to worry about getting cash, IC cards, refilling said IC cards, going to an actual bank with your passport, etc. Now all you need is an iPhone (although I hear Android phones from outside Japan still can't use suica).

I had a mixed experience with it. I think it has enormous potential but it needs to be more deeply integrated with their system (while staying read only by default, as you said).

What are Growlers doing performing aerobatic maneuvers at air shows? They have tens of millions in specialized extra equipment on board. Seems like a poor use of taxpayer money. Send regular F-18s, not the rare expensive ones that look the same.

My furnace is protected by an old school fast-acting fuse. One day it blew and at first I thought it was an anachronism from the house's original wiring but then realized it's intentional - the standard breaker upstream of it is not fast enough. Not clear if it mainly protects the blower fan motor or the circuit board - I suspect it's the motor. At least one other fan motor in the house got fried previously.

I think the quality of your power is determined mainly by the size of the transformer serving your neighborhood as well as the presence of noisy heavy power equipment like AC with poor/no soft starters or big brush motors among the consumers. It's noticeably worse on our street compared to where we previously lived.

It was one of multiple tools that were used to reinforce each other. The alphabet, of all things, obviously plays a huge role in cultural indoctrination and assimilation. You're being strangely defensive about this.

Tangentially related, one of the most underappreciated projects for print media and PDF generation is paged.js. It goes down the rabbit hole of paged media and the surprising complexity of it (have you ever thought about what it takes to render a table across multiple pages?) and provides a great foundation for solving these problems with sanity and using open web standards. It's a project that deserves more support.
