Looking at Wikipedia, there are still a few RBMK reactors in Russia - https://en.wikipedia.org/wiki/RBMK#List_of_RBMK_reactors.

Some of the design flaws of RBMK were retroactively addressed in existing reactors post-Chornobyl. In particular, the flawed control rod mechanism was addressed. It would cause power excursions/criticality when the rods were inserted. However, neither the high positive void coefficient nor the lack of containment buildings was addressed in RBMK. These unsafe features of the reactors led to the shutdown of the only two RBMKs that were ever in the EU (in Ignalina NPP).

While it is difficult to argue the idea that no reactor is capable of "Chernobyling", as "Chernobyling" is a very particular scenario, RBMKs are generally considered unsafe. The lack of containment buildings is particularly concerning because, without containment failure, we would not have had either the Chornobyl or the Fukushima Daiichi disaster.

While RBMKs are not built anymore, and the new Russian VVER reactors are much safer, they still don't meet EU safety requirements. A future evolution of VVER-1200 called MIR-1200 should, although it is difficult to find much information about this.

Overall, I am saying that "Chernobyling" can mean different things as several design and operation faults needed to align for that disaster to happen. Some design faults in Russian NPP reactors have been addressed, some not. Overall, VVERs look very safe as they address all major RBMK design faults, but for some reason still don't meet EU safety requirements. So I wonder what design faults persist. I do agree that Gen 3+ reactor designs look very safe.
AVs can seem to do that, but it's unintentional. I've never seen or heard anyone describe encoding intent with microbehaviors. The general preference is to make driving intentions as obvious as possible because some people don't pick up on subtleties and we still want to drive safely around them.

What you are asking for is checked exceptions where the caller gets notified by the compiler that the function you call might throw one or more exceptions.

However, it is worth taking it a step further and focus on "why the error occurred" instead of "an error has occurred".

An example of this is Code Contracts. Like Intellisense, live code analysis with contracts would tell you "the method you call will throw <exception-type> with the input you give".

Not only will that cover giving the user information about which error conditions that can arise, it will also give you the reason why.
My refrigerator works fine as long as the fan holds up. I’m not sure why they used such a terrible fan though.
> then you're doing a 50,000 row query, and that's ALSO going to be extremely slow, in terms of exclusive database contention

In the example the author gives the query cost is very likely dominated by finding matching rows in A. Where there is no index, then we can expect a full scan of A (or the index of A.id) for every batch of B.

This is the case no matter how many rows of B you are searching with; by running the query 50x you make this cost 50x greater. Using a join you pay it once.

In addition, and probably more to the point, the round trip database costs (serialisation, parsing, planning, scheduling, network comms) are going to dominate the actual query costs for something like this (unless A is exceptionally large).

Furthermore, the memory cost to the DB of the serialisation and parsing is likely to be much larger than just storing all those ids in their native format - and there would be no client memory footprint in a join. For the final result set the client can reduce their memory footprint by using a streaming result which every BigData DB supports, and most others too. If you are particularly concerned about client side memory it is best to either: do everything on the database, or manifest a temporary result table and batch out of that.

There are circumstances where the JOIN will be too expensive to do all at once. I've worked with what is claimed to be "BigData" for about 4 years and have had only a few situations like that; but none of them would be ameanable to a batching like this, and instead need much more complex architectural steps to make cheaper.

I have to agree with the GP comment. This is going to be a drain on both the undergrad programs and on the California taxpayers.

I am not convinced that the value add to the undergrad environment will make up for it.
The LEDs themselves are very robust, solid-state semiconductors that will function for a very long time, but they need additional electronics to function in a 110/220V socket, and those electronics seem to be crummier than the old incandescent filaments.
More importantly, I'm with the undergrads. Their tuitions shouldn't go up to pay for a bunch of whiny PhDs who could have worked in industry instead.
My experience here is the opposite. I have an Audi A8 and my girlfriend drives a Tesla Model 3. In my experience, the Audi is way, way more reliable when it comes to the features. The features just work for me.
I've never had any problems with the lane assist, for example, and I drive between 1000km and 1500km a week through Germany (not sure if the features are different depending on the location). I'd like if I didn't have to put my hands on the steering wheel that often but that's pretty much it.

Tesla's offerings are a real letdown. And they don't work as advertised either, which is why they're not allowed to advertise them in the same way anymore. It's missing way, way too many things that the car should notice. It's kind of like Siri. When it works, it's amazing. It often doesn't so you can't really rely on it.
We also had to replace a rim on the right hand side because the car simply didn't turn the wheel back. Girlfriend won't use the feature anymore now because she's kind of scared.

The summons feature doesn't work reliably either even when the conditions are perfect. The car just stops and you stand there and don't know why it's not doing anything at all.

I can't speak for BMW or Cadillac but calling FSD a decade ahead is ridiculous. It fails at so many simple things and all videos online confirm this and they don't seem to be able to really fix this. Every new Beta shows the exact same problems again and again.
If it's anything like the rest of the country most of those churches are dead and/or irrelevant. Showing up on Sunday, singing, and giving money to poor people isn't religion.

> there are roads in my town where unless someone waits and yields to let someone on a side street turn onto or cross the main road, the person on the side street is literally going to be stuck until rush hour is over.

It’s my view that this is a failure in road design, and leaving it up to drivers to make up their own rules is dangerous.

Understood this is the status quo, but I wish more would be done to address these types of situations because they cause stress and accidents
Shouldn't it be "pulling out", rather than "putting out"? Also, they already pulled out in October, this article is about their efforts to retain the developers that were working on the AI solution. And it's not "(all) german car makers", just VW and Ford (Ford apparently means Ford as a whole, not just Ford Germany?) - no idea how the self-driving plans of the others are doing...

Monocrystalline Si solar panels have so many advantages that it's hard to get interested in anything else for home or business construction. Lifetime is measured in decades, not years; efficiency is approaching 25% while prices are dropping (only expensive multi-junction III-V types are better, currently limited to satellite power systems); and for variable surfaces, they can be manufactured as small shingles as well as the standard size panel.

Unfortunately the USA, due to decades of minimal R&D funding, is well behind the technology curve in this area:

> "Some Chinese companies are defying the “more efficient = more expensive” rule in 2022. High efficiency solar panels are entering the market from companies like LonGi, Canadian Solar, and Trina Solar that surpass the 20 percent efficiency rating, but cost less per watt as opposed to SunPower, LG and Panasonic panels. Solar is cheaper than ever without sacrificing efficiency ratings, which begs the question if U.S manufacturers will be able to maintain their pricing premiums."

Of course a boom in solar PV installation in the USA would pull the rug out from under natural gas prices, which more-or-less explains government policy in this area.

Yes, it hurts me to see the social fabric tearing itself apart. It’s on us, people of “today”, to try to keep it in one place as best as we can and to pass it forward to those that will come after us.

> ince if I continue the conversation with my travel companion uninterrupted all the way to our room then I am actively tearing apart the fabric of society.

Yes, the social norms (of the past, at this point) say that you should interrupt the discussion with your travel companion and engage with the person from the other side of the counter (the hotel receptionist in this case).

Go isn't very safe and in general is a big mess with pointers and those zero-values. It gives you speed, a lot, but at a cost.
I want a self driving camper van not for the office commute but for travel. Imagine being able to leave after work on a Friday night, chill on the sofa with a few drinks, sleep and wake up parked anywhere within 14 hours range.

Then on sunday night you simply go to bed, wake up, have the shower and coffee and boom you're back at the office. Or if you work remote you could potentially work while the van drives you places.

It's weird and I'm likely in the minority here. I actually do like to be the driver when it's 4 or more hours. It's a way to be engaged in something.

There was a time when I was regularly doing 6 to 12 hour drives every other month or so.
I feel like there’s a great opportunity for a founder to start a new eCommerce site with supply chain verification to weed out fakes, and who would do their own testing a la Consumer Reports in addition to customer reviews.
Well, I've refactored large portions of Rust code with ease and I can't imagine doing it with any C/C++ code because I might break some invariant somewhere.
Indeed repairability may have been the biggest change. Major appliances centralize virtually all functions including on one or two main circuit boards including the high-voltage relays which in my experience are very prone to failure (they used to be mounted separately in a different location on older appliances). Those circuit boards typically cost ~1/3 the cost of a new appliance assuming you source and swap it yourself.

In conjunction with the decline of repairability in the appliances I think there's a corresponding decline in repair skills among the general population as well.

I hope not: people may then start optimizing for interaction specifically on HN and it will loose its appeal
Well, 3 seconds if you turn everything off, but it is not what we are talking about here, especially if the question is peak shifting. The majority of peak shifting is done at local level, with solution like, for example, domestic wall battery like Tesla or electric-vehicle-to-grid. Still not ideal, but I don't think your depiction of the situation is very fair if it presents it in a totally unrealistic way.

I also don't understand your argument about solar cycle: solar is producing close to peak hours, while nights are non-peak hours. So, in practice, it's not like you need to store the electricity locally for more than a couple of hours. I guess you are talking of a situation where the grid is 100% solar, but that's obviously a ridiculous scenario that no one has never pushed for.

I agree with the fact that the demand curve will become more extreme, and it is exactly the reason of my intervention here: this is a complicated situation, and it does not matter if the grid is mainly nuclear or mainly renewable, it is still problematic.

I agree that the storage problem is tricky and that the scale is a challenge. But this challenge still exist in full nuclear grid, unless we end up with a lot of idle nuclear plant running only few hours per day.

> what separates young earth believers from the rest of the church?

and I answered:

> Taking seriously the idea that the Bible -- and the book of Genesis in particular -- is the revealed Word of God.

The operative phrase there was "taking seriously". Many Christians profess to believe that the Bible is the revealed Word of God, but they don't really take it seriously. They play fast and loose with semantics and hermeneutics. YEC's don't. They believe that if the Bible says that the world was created in six days, then it means what it says: it happened in six 24-hour days. You crunch the numbers on the rest of the Bible's timeline and the result you get is a universe that is ~6000 years old, and so that must be the truth because God wouldn't lie. If the science says otherwise, the science must be wrong.

> Rust threading is only safe between threads accessing data structures in process own memory.

"Only". Intra-process shared memory is by far the most important kind of shared memory. 80% of the time you see someone advocating for message-passing multi-process over shared memory multi-thread concurrency or parallelism, it's because shared mutable memory is incredibly hard to get right in just about every mainstream language except for Rust.

> It does nothing for shared resources using OS IPC, or external resources shared among threads.

Only partially true. The very same language constructs which make shared memory safe can also be used to create safe wrappers for other shared resources.
This occurs in the US too. It drives me crazy when a two-lane highway turns into a one-lane highway for miles, despite a free lane leading up to the accident.

And any attempts to use the free lane will result in cars dangerously cutting you off.
> This has me considering the sound options for a next step [...]

I'm definitely not an expert but look into SA a bit out of curiosity. Sound analysis normally comes with significant restrictions. For example Astrée does not support dynamic memory allocation nor recursion (not too bad for embedded). There's likely more.

Let's consider the case of an iteration, with a number of loops unknown at compile/analysis time. What an unsound SA will typically do is unroll the loop a fixed number of times (5 by default for CC/ClangSA from memory). Obviously this could miss bugs if less than the actual number of loops.

To do better, a fully automatic sound analyzer would have to derive the relevant loop invariants and the associated induction proofs automatically, not to have to make any guess on the number of iterations. As far as I know this is still a research topic. Or alternatively, enforce a known, small enough bounds for any loop.

In general, either the sound SA must be able to derive quite complex proofs for the characteristics to enforce (research topic), or it must enforce simplicity to make the problem manageable automatically.

An alternative is a tool like frama-C that can kick the ball back to a human, to do the correctness proof manually using a proof assistant for automatic verification, if automation fails. And that can be a hard job.

The more constrained the application, the more realistic sound analysis should be. I don't know where a filesystem like OpenZFS sits here. Best of luck in any case!
To follow up with a more specific question,

Anyone know a good industry news site for Supply Chain related news?

I’ve been trying to understand how the global supply chain works better, the reasons it’s still pretty jacked up, and most importantly, what is currently being done about it
Ideally it would come from cutting the bloated administration that leeches off of research funding that professors and grad students attract, while impeding their work, but that's not going to be what happens.
I've been bitten by and tried to work around this as well. From what I can tell, the best you can really do is to parse by matching up parens, but someone could totally make a program with braces in its name. If I make a binary called "foo) R 10 20 30", the /proc/<pid>/stat entry will contain "1715376 (foo) R 10 20 30) 1544883 1715376 1544883...". It's terribly non-obvious how to deal with correctly.
I remember back in the mid-to-late 00s when OpenID seemed like the future…
Grad students aren't just "older undergrads who really like studying", they are researchers, assistants to professors, and teachers of undergrad courses.

For that reason, they deserve to be paid, and I would argue given their role presently and for the future of the country, they should be paid at least enough to rent a 1 br apartment and cook their own meals.
I'm talking about stuff like this, rhetoric that's common in anarchist communities: https://www.instagram.com/p/CmUY0cjKsIE/

"guess who shares legal responsibility"

They say this is why it's commmon for Tesla driving system to disingage 1-2 seconds before it knows the vehicle is going to crash.

https://www.motortrend.com/news/nhtsa-tesla-autopilot-invest...

The fly in the self-driving ointment is accidents are NOT 100% unavoidable for humans assisted by any technology.

People can jump in front of cars or intentionally interfere with said tech, for example.

There will be accidents, and the AI systems can predict with great certainty that a crash will occur before the human at the wheel does. In Tesla's case, it disingages before the time of impact to mitigate Tesla's culpability. (seemingly)

Well, that's also C's fault for not having parametric polymorphism.
Every time you drive a car or get in an airplane you're in the "When you don't know exactly how things will be affected" category, you're adding more Co2 to the atmosphere and thus warming the planet at a never seen before rate. We don't know exactly how things will be affected.
