You are both correct and the article discusses it accurately:

> Then you have 2048 bytes of user data, scrambled for the reasons mentioned before. The best way to look at the sector as a whole is to think of each sector as 12 “rows” consisting of 172 bytes each. After each 172-byte row is 10 bytes of ECC data called Parity Inner (PI), which is based on Reed-Solomon and applied to both the header and scrambled user data per row within the sector itself. Then, after the user data and parity inner data, is the 4-byte EDC, which is calculated over the unscrambled user data only. Then, finally, Parity Outer (PO) is another form of ECC that is applied by “column” that spans over an entire block of multiple sectors stacked horizontally, or in other words, a group of 16 sectors. Altogether, this adds up to 2366 bytes of recorded sector data.

Grim reminder that we put our faith in algorithms run by people who think "move fast and break things" includes human brains.

OpenAI claims the bot was just a passive "mirror" reflecting the user's psychosis, but they also stripped the safety guardrails that prevent it from agreeing with false premises just to maximize user retention. Turns out you're arming the mentally ill with a personalized cult leader.

My house once had knob and tube wiring. Over the past 15 years I have replaced most of what I assume is the second-generation cloth-covered wiring (which dates back to the 40s, 50s, and 60s). Every once in a while, I come across the insulators from an older electrical system, but most of the wire that went with those insulators was pulled out long ago. The only remains are short bits of wire that were wrapped around the insulators.

> Still somewhere between 10 and 25%, though.

This is basically almost public information: 25% cut on earnings between $10 million and $50 million.

Yet most likely very big share of sales is well below $10 let alone $15 due to sales and regional pricing.

So yeah I doubt numbers anywhere close to those adverised.

> Generally, the Steam cut is considered “fair” for Indy devs. The benefits of steam (discoverability, massive audience) generate more sales. My Indy dev friends are not upset about the steam cut at all.

Steam no longer provide any discoverability on its own unless you either bring your own community ftom outside or spend $10,000-100,000 on marketing to gain wishlists.

> Similarly, I don't understand why the CxOs in my current (BigTech) company still work. You're done. You can do anything you want

Has it occurred to you that perhaps what they want is to be the CxO of a big tech company? There’s a lot of power, prestige, and impact on society that you can’t easily get if you quit. And maybe they really enjoy the work itself too.

Good read. I had an offer for a mere 7 figures and that was hard enough to turn down. I couldn't imagine 9 figures! But I think I do get it, at least as much as I can get it at my level. It's hard to give up something you've poured so much of your life into -- "your baby." You lose the autonomy to continue shaping what independence looks like for yourself, or at least it felt that way to me.

There are many other dangerous ideologies out there. Having said ideologies should be allowed (freedom), doing bad things of the name of said ideology shouldn't.

ChatGPT can tell me that I am a "Very Stable Genius" and that my "I.Q. is one of the highest", all that means is that it can repeat stuff from X conversations it was probably trained on. Especially a non-thinking model is really just a glorified parrot. You should not be expecting any real analysis from LLM responses.

I remember reading an analysis of that a while back but I can't remember where I saw it. The upshot was that the industrial revolution turned on more than just innovation, it also required just the right combination of natural resources (coal) and economic conditionsL deforestation in England driving the use of coal for heat, which drove mining, which drove the need for pumps, which made Savery's engine economically viable. Before that steam power would not have found an application.

Also, the piston and cylinder (which came later) were derived from canon-making technology, so that had to come first too.

It does seem like a lot of apps continue to function on GrapheneOS after the "Play Integrity" check fails (or at least after Graphene notifies the user that the Play Integrity API has been called). I suspect either:

A) These apps have implemented only the check so far, and will eventually refuse to run or limit functionality at some point in the future.

B) These apps have noted the failure and certain functionality, especially communicating with servers to load "protected" content, will fail even if the app otherwise continues to run.

When I was around 10yo in the early 1980s in New England, I loved to watch the Computer Chronicles - which usually was shown late at night for some reason. It's hard to describe now how awestruck I was at everything the show covered. I was too young to understand what a studio was, so I really thought they were filming from some far away skyscraper with a view of the city behind them. I wanted to be there! I still get that buzz of excitement and wonder when I watch recordings even today.

After moving to Silicon Valley, one of the things that still gives me joy is the idea that I now live close to where the show was recorded in San Mateo. It's one of those small dreams as a kid that became reality.

RIP Stewart.

Well I don't think residential kitchens are as chaotic as a commercial kitchen, so sure drinking out of a non breaking container is probably a good idea (glass breakage is a pita there).

However most people (I assume on HN) are not line cooks and do not work in commercial kitchens. I drink out of glass (don't want plasticy taste) and use glass to store leftover food.

Here's one: "There's a reason most line cooks drink out a deli rather than read NIH" [0] :)

Things like https://github.com/textcortex/claude-code-sandbox seem like the bare minimum. There are a few other projects doing this.

The first threat is making edits to arbitrary files, exfiltrating your SSL keys or crypto wallets. A container solves that by not mounting your sensitive files.

The second threat would be if Claude gets fully owned and really tries to hack out of its container, in which case theoretically docker might not protect you. But that seems quite speculative.

> Liberals vehemently opposed the idea, calling it 'regressive', meaning it would be socially backwards, but the idea held appeal as a simple and fair way of "taxing everyone equally"

I'm not sure what you mean by "socially backwards".

"Regressive" and "progressive" are terms of art in tax law and theory. A tax is regressive if people with less income pay a higher percentage of their income toward that tax than do people with more income. Progressive is the opposite.

Sales taxes are regressive because most people with lower income necessarily spend a higher percent of their income than most people with higher income, and so even if a sales tax is the same percentage of the sale price of items lower income people end up spending a higher percentage of their income on sales tax.

A girl that was my friend some years ago was having a psychotic episode once, and I told her that no one is following her, no one is monitoring her phone and she probably went schizo probably because of drug abuse. She told me I'm lying ans from the KGB; she went completely mad. I realize that this is actually dangerous for me and completely cut ties, although I sometimes browse one of her online profiles to see what she posts.

The problem is that packaged Java CLI utilities will also take 20MB+. The minimum size is still much too big for that class of programs. Also, AoT compilation was an absolute pain last I tried it, it's a big change for an ecosystem that was always designed as modular and dynamic. I love Java, but for CLI apps I'll take Rust whenever possible.

Perhaps, based on specific context, let the Law's vote!

to throw everything out and start over.

IMHO: Law 31 is the kicker. That triggers Law 11. With general support from Law 16.
SaaS – Cost Accounting

China couldn’t jump past the fossil fuel stage of technology development, but now its technology development and gigantic manufacturing capacity allows it to help poorer nations fully bypass that stage.

I think it’s entirely possible that giving first world money to poor nations to buy Chinese solar and batteries is a more cost effective solution to carbon emissions than paying western skilled labour wages to decarbonize energy production in the west.

Of course, I’m sure you’ll have tremendous success convincing “candy for dinner” American voters to pay third worlders to spend in China

> There's just no way in hell ChatGPT at its current level is going to guide you flawlessly through all of that if you start with a simple "I want to build a raytracer" prompt!

This is the entire crux of your argument. If it's false, then everything else you wrote is wrong - because all that the consumer of the book cares about is the quality of the output.

I'd be pretty surprised if you couldn't get a tutorial exactly as good as you want, if you're willing to make a prompt that's a bit better than just "I want to build a ray tracer" prompt. I'd be even more surprised if LLMs won't be able to do this in 6 months. And that's not even considering the benefits of using an LLM (something unclear in the tutorial? Ask and it's answered).

> Essentially, it means the number cannot be constructed using a finite combination of integers and standard algebraic operations (addition, subtraction, multiplication, division, and integer roots)

Slight clarification, but standard operations are not sufficient to construct all algebraic numbers. Once you get to 5th degree polynomials, there is no guarantee that their roots can be found through standard operations.

I listen to FLAC's mostly (high quality, loseless audio files - CD quality or better) most of my collection has come from ripping CDs I owned or checked out from the library or albums bought on bandcamp, quobuz, and ototoy.

I use Rhythmbox to listen to files on my PC (Linux) - I think they have/had a Windows port at some point. VLC works too but is more cumbersome for large libraries on desktop IMHO. But VLC is actually pretty good on Mobile (iOS/Andriod.) besides the pain of syncing files over to iOS.

I splurged on a dedicated DAP (Digital Audio Player) last year that I'm mostly happy with: a HiBY R1 (my two complaints are: 1. for whatever reason it refuses to pair to my car's bluetooth, no issues pairing to numerous other devices. 2. It doesn't remember what you were last playing when it shuts off.)

Do you have any idea just how much code is in Windows?

I did a quick search and estimates are in the 50-60 million lines range.

No way in hell are they going to rewrite all that in a few years. Even if they actually wanted to, which they don't because it would be a truly enormous expense (even for Microsoft).

Not to even mention that huge software projects have a well deserved reputation for failing, and the scope of such a rewrite would probably dwarf any previous rewrite of anything, ever, and by a very large margin.

"Rewrite all of Windows in Rust" simply does not even begin to pass the sniff test.

Load stuff directly into dishwasher and as soon as you decide you don't need it.

In general small cleaning tasks are great filler for any wait in dish-making

I got a bunch of time-saving (or at least time-sync-effort-having) from just air-fryer option to run 2 programs at time (basically set different times and it will take care of starting them in such way they both finish at once).

Put carbs like potatoes in one chamber, meat in other, set and start it, make some salad/tea/whatever else in mean time, 15 minutes and done.

> Especially because getting the water boiling is so often a limiting factor, it's worth considering this sort of optimization. I probably spent extra hours per year cooking before I changed how I boil water. There are many common tasks like this in the kitchen; it's worth thinking carefully about them.

Prepare stuff while it boils, like, you either boil stuff into stew in the water or boil some kind of pasta or other carb there, surely there is plenty of other parts of the dish to make in meantime?

Any kind of government encroachment into the time of it's citizens is theft.

Many of their citizens chose American social media because they prefer American values. This offended the nationalists so they are simply going to ban American sites and try to make their own inferior ones.

Traditional media (Murdoch) and traditional gambling lobbied the hardest for these laws (of course these are anything but traditional). This is a billion dollar gimme to newscorp, but they will probably still fail to pick up the younger audience because they can't compete.

In America we have freedom of religion and freedom of association, we used to have the freedom to put whatever we please in our own bodies and minds.

Living with a shared kitchen I had a neighbor (+gf) once who hated cooking. His solution was to cook only once per month. It was quite hilarious, he made about 40-60 meals in one day. Giant pots everywhere.

He would print a menu card for the month with all the 3-4 course meals. He would set the table, light candles, poor the wine and argued what to microwave.

If you need proof that delivering cutting edge services requiring split second decisions and multiple highly qualified people who are liable to the tune of millions of dollars for each decision is not complicated, then we are living on different planets.

> If you wanted to construct a logical chain of reasoning, that would be far more interesting than repeating another round of simply asserting that the status quo is inevitable.

You are welcome to explain why an insurance company would want to make things so complicated. They don’t make it so complicated for claims on a vehicle or a house. They are earning meager profit margins with the situation as is. There is literally nowhere they could go except up…why are they choosing not to?

And if you can come up with a more efficient system to administer insurance, I’m sure a few rich people like Dimon and Buffett and Bezos would be interested in your services. These two “titans” of industry couldn’t figure out how to make it better.

The Tolstoy riff is a great hook, and the “monomyth” framing works mostly because it’s really describing an incentive gradient. Early on, the environment is information-dense and socially novel, so you mistake energy for trajectory. Then the organisation’s needs assert themselves: teaching, outreach, grant theatre, internal coordination. None of that is (necessarily) evil, but it competes directly with the one thing the postdoc is implicitly there to convert into a future: publishable research. So, calibration isn’t a mood shift so much as a budget update. In Campbell's terms, the dragon is the calendar.

What I’d love to see (maybe as a follow-up) is the structural question: what policies reliably prevent the “service creep” phase from eating the research phase? I suspect the answer is boring and contractual, which is exactly why it might matter.

Of course you should put down a real assertion when you have a condition that can be cheaply checked (or even an assert(false) when the language syntax dictates an unreachable path). I'm not trying to argue against that, and I don't think anyone else here is either.

I was mainly responding to TFA, which states "How many times did you leave a comment on some branch of code stating 'this CANNOT happen' and thrown an exception" (emphasis mine), i.e., an assertion error alongside the comment. The author argues that you should use error values rather than exceptions. But for such sanity checks, there's typically no useful way to handle such an error value.

Going to be honest

Absolutely shocked Java wasn’t in the terminal

I know I don’t use it, but wow.

Honestly, super impressed that that they’ve got the traction they do without it but, I think the takeaway is that Java developers like having everything in the IDE— so I’d imagine agentic in the ide will yield higher returns than switching modalities
