>I find it mildly amusing that there are so many people claiming that it's 100% on one side or other, when it's trivially easy to see why that can't be GUARANTEED TO BE the case.

To be fair most people on one side think they know better than Adam Smith and the people on the other side usually never opened a book, so it's a tough bargain.

> My Dad lost his Dad at the age of 34, which is no age at all in the grand scheme of things. By contrast I still have my Dad at the age of 60, which has meant an extra quarter century of guidance, support, advice, love and always being there. How lucky am I?

I lost my father when I was 30. I thought I’d been lucky because I’d had him through my “adult” life. Now I’m 40 and have a 2-year-old son, and over these past ten years I think it’s when I would have most liked to have him — when more questions came up about what he was really like as a person, beyond his role as a father. He died at 72 from lung cancer; he had been smoking since he was 13 and never went to the doctor. I guess I was lucky after all…

NEC doesn't really make vector processors anymore. My company installed a new supercomputer built by NEC, and the hardware itself is actually Gigabyte servers running AMD Instinct MI300A, with NEC providing the installation, support, and other services.

Great project! You chose to base on Mermaid.js and that is indeed the most popular declarative diagramming library right now. A more versatile declarative diagramming approach is provided by the D2 Language [0], which may be interesting to check when it comes to supporting more complex diagram types.

It will vary by domains. I work in games, so unlearning OOP and understanding data oriented paradigms helped immensely understanding how to optimize.

But I'm not a data oriented evangelist. Part of that paradigm is understanding the size and predictability of data, and not everything in games meets this. Input is the most obvious example. But knowing when and where to use such techniques is arguably what separates an engineer from a programmer. But schools can go a tad overboard focusing on one technique.

Unlearning can also help you appreciate OOP more as well. I wouldn't have dug too much onto c++ vtables without a goal to understand why Polymorphism can be so slow. But I can also appreciate how clever the implementation is to get that far to begin with.

So for a simple example:

Suppose 1/20 people are sadistic, and 1/20 people love eating bitter food.

Let's suppose each question is multiple choice with a T/F.

Let's suppose also 1/10 respondents are bots that answer randomly.

Of the people who answer they like sadism on a given question, 66% will be bots. And of the people who say they like bitterness 66% will be bots.

For simplicity sake consider a simple two-question survey (one question about sadism, one about bitter food).

In this case you will get the following numbers, even if there's no genuine correlation:

[One bot in each category] - 1/40 like both

- 3/40 like bitterness but NOT sadism

- 3/40 like sadism but NOT bitterness

- 33/40 like neither

So you would conclude if you like bitterness (4 people) you have a (1/4) 25% chance of liking sadism, whereas if you don't like bitterness (36 people) you have a (3/36) 8% chance of liking sadism. Therefore liking bitterness would appear to predict to liking sadism (when really both are just predictors of being a bot).

The exporter may sell less to the US, but typically they will then sell the difference into non-US markets, reducing the impost. This is exactly what happened in a lot of (not all) markets a few years ago, when China tried to intimidate Australia with trade restrictions [1]. When Chine dropped the restrictions, they found that they were now competing with more buyers and so paying higher prices.

The temptation to start a competative private leader board will be great, just for the mentioned reason. I have a reference my scores in my CV. The competative part of AoC is one of the things that I find attractive and also has taught me some valuable lessons about coding, like taking some time to review the code the first time before submitting. I experienced several times that I spend of time to debug a small bug due to a minor error, that I could have caught had I spend some time reviewing. Especially with the first puzzles, I try to get it right the fitst time with respect to compiling and execution.

I will search for a pure C private group to join that only allows a small library for things like reading the input as an array of strings.

> And with that, I had to remind myself: Advent of Code isn't about there being 25 puzzles

Really? The name of the event is "Advent of Code". Having 25 puzzles is easily its most strongly-determined aspect.

You could argue for 23-29 puzzles, or perhaps for 5, but at 12 what's the name supposed to refer to?

> Well we're probably going to see flow batteries take over

Its unlikley, they are a massive pain to manage compared to lithium, expensive and have poor round trip efficiency. Oh and terrible energy density.

I'm not saying its impossible, but I'd be surprised.

I think the biggest two factors that play against them is that they round trip efficiency is something like 70-80% compared to 90%+. but the real pain in the arse is the charge managment. From what I understand, you need to charge them to full, and then discharge them fully. I don't believe that you can charge from halfway.

Most power markets work in 30miunute chunks, so managing charging/discharging would be really hard.

I’ve been using AI coding systems for quite some time, and have worked in neural networks since the 90’s. The advancements are, frankly, almost as crazy as 90’s neural net devotees like me were claiming could be possible in the eventual future.

That said, the non-tech-executive/product-management take on AI has often been an utter failure to recognize key differences between problems and systems. I spend an inordinate amount of time framing questions in terms of promises to customers, completeness, reproducibility, and contextual complexity.

However, for someone in my role, building and ideating in innovation programs, the power of LLM assisted coding is hard to pass up. It may only get things 50% of the way there before collapsing into a spiral of sloppy overwrought code, but we often only need 30-40% fidelity to exercise an idea. Ideation is a great space for vibe coding. However, one enormous risk in these approaches is in overpromising the undeliverable. If folks don’t keep a sharp eye on the nature of the promises they’re making, they may be in for a pretty wild ride; with the last “20%” of the program taking more than 90% of the calendar time due to compression of the first “80%” and complication of the remainder.

We’re going to need to adjust. These tools are here to stay, but they’re far from taking over the whole show.

Question:

I see that you have a lot of energy to fight for what is right and that's great!

Have you considered directing that at the vendors? Any vendor. Roborock, Dreame, Ecovacs, whoever.

These are those responsible for why you are still being forced to engage with me in some way. And you have a clear paid customer relationship with them. They must listen.

Imagine how great it would be if my whole project would become entirely irrelevant, because there is a proper vendor solution with paid commercial support and without some weird ideological Hardliner.

That to me sounds like the ultimate win. It would even side-steps me completely, stripping me of all my undeserved autocratic power.

Instead of fighting over a tiny cake, what about making that cake much, much bigger? Just some food for thought.

What exactly would be “practical” about exporting an ordering table when your application doesn’t need it? That’s the whole point of minimal perfect hashing — to provide a compact, collision-free mapping from a known key set to [1..n], without extra structures unless they’re required.

If you do need to preserve key order, that’s a different problem entirely — and one that’s already well-studied. You’d use an order-preserving MPHF (OMPHF), not a standard MPHF. There’s a large body of literature on this (e.g. “Order Preserving Minimal Perfect Hashing” – VTechWorks, ).

You seem to conflate the two problems — building an efficient MPHF versus building an OMPHF. Both are useful, but for different goals. Dismissing something as “academic” because it solves a different problem efficiently isn’t a fair critique — it’s misunderstanding what it’s optimizing for. It’s like saying “Bloom filters aren’t practical because they don’t store the original data.”

Could ask the same from you really, but then you followed me here out of spite from the other subthread to just loosely regurgitate another person's reply [0], along with your lackey [1], trying to make it a touch more hostile on the way, so I think I do know the answer to that one...

> If you're not interested at all, why did you even join the conversation?

Or was this a genuine question? I don't think you do those though. Are you then maybe getting tripped up on your own dumb headcanon? Cause honestly, given that this would be the third time in this thread that you're conjuring up a strawman and twisting words, you have to appreciate I have a hard time believing anything coming out of your mouth (keyboard?) at this point. It's almost as if there was a reason I went off about what I did, and it's coming back to bite you in the ass now...

To you, is a suggestion for someone to explain their own thoughts in their own words, rather than link to someone else's, a sign of no interest at all? Did I really say that I wasn't interested in what their take was, or did I say that I wasn't interested in receiving another barrage of GNU links? Careful, the latter one doesn't even require thinking, only bare minimum intellectual honesty, seemingly your Achilles heel.

External contamination is not comparable to internal, at all. Bq is a terrible unit to understand radioactive danger. Doses are usually detected in Grey, then converted into Sievert because Grey didn't take into account the difference between Alpha radiation and the others. And even then, when someone is truly contaminated, we calculate effective dose per organ.

The poor guy who fell in the pool probably didn't take any Alpha ray, wasn't taking all the radiation on a specific place, and while in my country we would calculate the dose he took before sending him back to work, he would probably work again in the same nuclear sector (this isn't the case for anyone, I know someone who dive to get the radioactive/explosive/poisonous trash we put in the water in the 50s until the 90s, he now cannot work on any radioactive trash.)

Yes and I would like to add, it is all about the "dose". It is a common misconception that tangled DNA will automatically lead to spreading cancer. Per day a normal person develops tangled up dna cells in the hundreds, that is a normal process, but the immune system can handle it without problems and can get rid of it (unfortunately not always). So with Asbestos it is all about the dose too. Although a relative small amount could be already _potential_ harmful.

So you are correct about Tesla's valuation but the market and all it's millions of participants as well as analysts, who have price targets well above the price now, are wrong. Erm ok. The stock price is whatever someone is willing to pay for it so it can't be 'overvalued'.

I guessing you would think a Picasso painting selling at $10 million is way over valued as the paint and canvas it was painted on are only worth $50.

I'm currently trying to learn more about how the boot process works, specifically with UEFI. Yesterday I watched a video on how to program a UEFI bootloader so I was happy when I saw this article this morning.

The article jumps over so many steps and leaves out so many mechanics that I had to stop reading, because it just opened more and more questions without closing any. For example, right at the beginning:

> Right after reset the CPU jumps to a special address called the reset vector at 0xFFFFFFF0. Think of it as a permanent bookmark that says “start here.” There is room for almost nothing at that address, so manufacturers put a short jump there that passes control to the firmware on your motherboard.

What does that even mean? It jumps there means that it executed whatever is at that address, but it failed to explain how the instruction at that location is even put there in the first place.

Reading a little more I truly am confused for who this was even written. It seems you need a lot of prior knowledge to understand what the author talks about and then it also makes me wonder what additional information this article conveys if you already can fill in the gaps.

no grandma or auntie can do that with 30 kids. seriously, you have to observe a montessori kindergarten in person to get what is going on there. and do some reading on how it works. the difference to regular kindergartens even with good teachers is massive.

you are underestimating how much effort it is to calm down a large group of kids. motivation alone is not enough for that. it does require training. if it didn't, then we would not require trained teachers to run a kindergarten group. it's not window dressing at all. and the montessori training and method is simply better and more effective than regular methods and training. and it doesn't need a filtered peer group either.

> But just to be sure, I got in touch with a friend of mine who works at a research reactor, and asked him what he thought would happen to you if you tried to swim in their radiation containment pool. “In our reactor?” He thought about it for a moment. “You’d die pretty quickly, before reaching the water, from gunshot wounds.”
by 7bit | 2025-10-26 10:42:51+00:00
It's fine to explain things to people that are not into that topic. But I also wonder what the target audience is. On one hand, he explains what a hexadecimal ist, but then jumps over essential information needed to understand the boot process. It's like: "Learning to swim: This is water, it is wet, if you jump in you sink and in water you cannot breath. Then you start moving your body parts and then you swim."

I don't really think asbestos is something that needs balance to the conversation. It's like radioactive material, you will most likely not even know that you've had too much exposure until your health is already permanently affected. The illness may manifest a considerable time later so you might not even know what it was. It's very easy to unknowingly be exposed when e.g. renovating a house or other similar arrangements because there is no easy visual way to identify materials containing asbestos.

This matches my experience, and I've been 'nervously' anticipating this year's Advent of Code. I managed to keep to the spirit last year and get everything done by Christmas day (though admittedly with some days bleeding over into other days due to pesky family/other commitments), but even this relied on having the last week or so of the month be relatively free for me.

While I've usually been able to do the first half of the month's puzzles in the day before breakfast, over lunch and in the evening, the increasing difficulty does mean that later puzzles can really eat into a day, particularly if you happen to go down a bad path for your solution.

I'm not a doctor or researcher in that field, but my understanding is that cancer is not 'one disease', but rather a huge number of different diseases which mostly have in common that they develop some kind of tumors.

That's also one reason why progress in cancer research and drug development is so slow. 'Fix' one cancer, and what you've developed likely has little effect on the zillion other cancer variants.

Indeed, it was a radical feature in 2015. The marketing name for SPARC ADI was "Silicon Secured Memory" and the marketing material from that era [1] says:

Some programming languages such as C and C++ remain vulnerable to memory corruption caused by software errors. These kinds of memory reference bugs are extremely hard to find, and victims usually notice corrupted data only long after the corruption has taken place. Complicating matters, databases and applications can have tens of millions of lines of code and thousands of developers. Importantly, errors such as buffer overflows are a major source of security exploits that can put an organization at risk.

It's little sad that the SPARC arch is no more and even after 10 years, we still don't have this feature in mainstream CPUs.

CPM doesn't mean anything, it's useless to compare it to anything without more information.

For his job, depends on the dose he took. In my country he would have been on benefits until the dose was calculated, then if possible, reintegrated in the team, or directed towards a new job if not (paid formation and everything).

You’re right, you don’t know! When I worked on a nuclear aircraft carrier, I learned that the people working down in the reactor spaces got significantly less radiation exposure than the people working on the flight deck. My ship was ported in Japan when the Fukushima disaster happened, and we had to abruptly go out to sea because we couldn’t let the (minimal) fallout contaminate the reactor spaces and make it impossible to monitor the reactor itself properly.

This month, London police discovered and intercepted a shipment of 1,000 stolen iPhones destined for ... China.

"46 people were arrested, including two men who were detained in London last month on suspicion of handling stolen goods after 2,000 phones were found in their car and addresses linked to them."

These aren't local street thugs. This is a massive, global criminal enterprise:

"London Metropolitan Police, which had initially assumed that "small-time thieves" were behind the city's wave of phone thefts, got their first major lead on Christmas Eve last year. A woman using "Find My iPhone" had tracked her stolen device to a warehouse near Heathrow Airport."

"We discovered street thieves were being paid up to 300 pounds ($403) per handset and uncovered evidence of devices being sold for up to $5,000 in China."

1- To have a website that acts as a gateway for the nostr websites, but this way we will lose decentralization 2- To build an app that can directly access the websites "Nostr browser" 3- To have an extension that acts as the gateway for nostr websites

We went through the 3rd option which provide the easiest and mostly native way to access the websites

> because there's no well-defined meaning to the title of "CTO". Our "CTO" codes,

Amen.

I am a CTO, but spend most of my day coding. I was brought onto a smallish/medium sized company to get their base tech into the modern age, build LOB apps to improve some workflows, and ultimate build a new EMR in that space to replace the one the company is using.

I don't have anybody that reports to me. I'm one of 2 tech people in a company of clinicians and doctors. There is no budgeting or reports I have to generate.

But, it was the only title that made sense given my role in that specific company.

Anytime someone asks me I always have to add "but I don't really do CTO things".

> The October 7 attacks were terrorist attacks. The literature on terrorism is they extremely rarely achieve their political goals.

Is every act of violent resistance against one's oppressor a "terrorist attack", what does the literature say? What distinguishes a terrorist attack from a counter-offensive?

Is it the targeting of civilians? But that didn't start on October 7th, so if that's the case, why isn't Palestine getting everything they want, and why aren't you arguing that Israel shouldn't expect to get anything out of their terrorist attacks against Palestine?

Last one is a rhetorical question, we know the answer by now. Israel and the US have all the power therefore their actions are righteous and any sort of retribution is terrorism, propped up by a million different ways to try to erase and rewrite history.

Phrases such as massive red flag and bureaucratic nonsense were claims you knew better.

Who claimed the event was normal? A worker falling in non contaminated water would not be normal. Many things are bot normal and not emergencies. False dichotomy and straw man are logical fallacies.

Were the plant cost and status meant to support your claim 300 counts per minute was a red flag? They appeared irrelevant.
