Ask HN: How common is publishing line item costs with a product?
I've seen this just a few times and I thought it was cool to see a cost breakdown of some item or service. It could be broken down in various levels of detail, aggregated by materials, labor, and overhead, or down to individual component costs.

Have you seen this practice? Is there a name for it? Are there good reasons why this not a good idea?

The consumer is always the last to feel anything beneficial from the economy.

In 6 months to a year when it's finally obvious that cash is going to be worthless for awhile, they'll increase rates to encourage unsavvy customers to take the hit for it. This way, they siphon off 5% of everyone's real world wealth and as an added bonus it looks like they're doing everyone a favor.
> In the mean while, there is one fundamental tool which is under utilized, the data diode.[1] With such a device, it would be possible to monitor a system from the outside world (via the internet, etc.). A polling loop sends data out in a continuous manner (with forward error correction), and a matching server receives the data, checks for errors, an then makes it available to the outside world.

Something like that was implemented at Amazon in the early days using a modified serial cable that prevented credit card information from ever exiting the payment system even if the web servers were compromised.

Obviously because they can't afford to because they actually have to work.
I think fundamental elements of the system are broken such that we even landed on a two party system in the first place and it’s more of those types of changes I’d like to see. In terms of ideology Parties change all the time. Look at the transformation the GOP has had over the last 10 years even. That I’m not worried about, but issues like term limits to prevent the effective gerontocracy we have, ranked choice voting, stopping arbitrary district restructuring, effective representation by population and more are things that benefit both existing parties regardless of their current ideology and so they don’t stand to change.

I also go back and forth on the electoral college in the case of the president but I’m not quite at the point where I want it to disappear without having an alternative.

I’m not debating if the US method of measurement in recipes is terrible or not (it is!). But taking an imprecise unit of measurement and lossy converting it to another is better (edit for clarity what I meant) each time you cook, while in the middle of cooking!?
Perhaps, but blocking 53 is better than not, IMHO. I've seen devices fall back once blocked to a hard-coded dns, so it works today. DoH is another that devices will eventually employ, so that's another whack-a-mole situation.

For baking, I'll generally weigh and, for flour, pretty much always. However, I use measuring cups all the time for other cooking where recipes may not even give a weight equivalent to a volume of something.
Which evidence? You just quoted absolutely zero evidence beside your own personal anecdotes.

It's an airborne disease. Better aeration definitely helps with airborne diseases, multiple studies prove it.

https://pubmed.ncbi.nlm.nih.gov/17257148/

But of course, COVID spreads so easily that this can reach the limit (especially Omicron) and in an environment where kids will interact together in all kind of ways, but this would have definitely helped a lot more in the first few waves (pre-omicron) without needing to shut down schools entirely.
I think you also need to consider direction of spread. It is easy to see how spread from an individual is cut with masks. Spread to the individual is almost certainly affected, but to really cut it down, you almost certainly need gloves and a ton of hand washing going on.

But, again, I am /not/ arguing against masks. I fully agree that if you are sick, stay home and wear a mask when you do go out. My point is that much of the reduction is more easily explained with "stay home" than it was "a lot of folks were wearing masks." I further agree that both had an likely had an impact. But, just as having a more streamlined car will give you better gas mileage, if you are trying to make a bigger impact, you are almost certainly better focusing on buses than you are personal vehicles.

Boring technology is not necessarily the same thing as older tech. Lisp, for instance, is much older than Java, yet Java is clearly in the category of "boring" technology, whereas Lisp is quite the opposite despite its age. It seems that for tech to be "boring" means merely that it is a safe choice for the task at hand, a tool that will certainly do what needs to be done, with the kind of ecosystem and stability that leaves little room for the unexpected, for exploration. There is no significant uncertainty involved in the use of such technologies, which makes them "boring".
Knockout was an abject disaster. We almost immediately ran into performance problems. Coupled with its own limited ecosystem we had the same problems as you experienced with React, but ended up in a far worse place.

I have reflected on what happened quite a bit and I can't think of any redeeming aspect of that technology choice. It really was the worst possible move and it was entirely motivated by the "boring is better" argument.

I'm sure all drivers did not stop at stop signs immediately when they were introduced. And I still see people not stopping at these signs. I still believe they're good regulation and the more people know it makes roads safer, the more they respect the signs. Same with seat belt.

So in general when people talk about improved ventilation, they're _mostly_ not talking about opening a window (impractical in many places at certain times of year, anyway); they're talking about some sort of mechanical ventilation, particularly for large buildings.

It is very heavy on the jargon indeed. Just in case someone's wondering, the author isn't being facetious it really is a very simple thing. If you google 24C02 you'll get a PDF that probably has this exact schematic in the application examples section.

If you want to take up electronics design as a hobby, you'd probably be at the level where you could have this designed and manufactured within a month or two of evening/weekends studies.

edit: Just for fun, let's go through the jargon. 24C02 EEPROM is the name of a popular chip that stores a tiny bit of persistent memory. Mouser at the moment has more than 80 variations of this chip with hundreds of thousands in stock and hundreds of thousands more in back order. 4.7k pull-ups, this means there's a small resistor between the signal lines and the positive voltage rail. This enables the chip to communicate by pulling the signal low (by shorting it to ground) this way of signalling is very common, someone told me it's because how the telegraph worked but I'm not sure if that's true. I2C is a simple communication protocol that works if chips are really close together (i.e. I think guideline is within 10-15cm). A bypass capacitor is a component that blocks continuous voltage but lets oscillating voltage through. Most chips don't deal well with oscillating voltages on their power supplies so the manufacturer will recommend you (through that PDF I mentioned before) to put a bypass capacitor between the power supply line and the ground, so that the dirty oscillations go directly to ground instead of into your chip. A diode is a component where current can only go in one direction, in this case that's handy because chips usually break if you wire them in reverse polarity. If a user would force this cartridge in backwards, instead of the chip blowing up, the diodes will simply block the current from coming in the wrong way and the device won't work.

And that's it, I think all you need to understand how this cartridge is designed.
This seems extremely unlikely to me.

> But some scientists theorize that this virus may have always been responsible for a portion of the small number of unexplained pediatric hepatitis cases that happen every year.

This doesn't feel like something that needs to be theorized about. Were the hepatitis instances depressed during covid? If integrating since the start of covid until now, do the current cases push the hepatitis caseload beyond the comparable average in preceding years?

Articles like this are frustrating. Obvious questions unanswered. No information as to the identify of "some scientists".

I think such unclear reporting triggers conspiracy theories by making people feel as though information is being hidden. I don't doubt that this is incompetence rather than malice, but damn, humanity needs to fix the journalism problem.
Anyone less familiar with the field should be aware that it’s widely known that the benchmark used for this list (multiplying two huge dense matrices) is not representative of many real use cases in scientific computing. So while it’s fun to push this one number higher, one has to ask if it’s really worth the incredible amount of money involved, when it’s something of a drag race.
Long, LONG ago, I wrote a little program to predict hard drive prices. It worked well for a few years, and needed some tweaks, but was quite the conversation starter. I looked through the oldest hard drive ads I could find, and extrapolated. I added a factor for a "base price" because nothing below that number would be a viable retail product.

The proxy _is_ pretty nasty design. Basically every time `golang` fetches modules, it uses Google's proxy out of the box.

This lets Google collect very granular data on who uses which modules, and also makes it opaque to webmasters who's using their services (it's all hidden behind google). It's honestly pretty nasty how Google has hidden this kind of "analytics" within a pretty dark grey area.

At the same time, the bot that handles the proxy seems to crawl everything, very often, and excessively, effectively DDOS'ing anyone hosting go modules.

> people probably want a washing machine that can keep track of it's duty cycles and let you know if water quality is affecting it's performance or if a part is getting close to end of life

Sounds good, but you can do it with a few sensors leading to an LCD screen (and a manual in a yellowing clear plastic bag taped to the back of the machine.) And you don't have to disable the machine if that microprocessor burns out, or god forbid put an entire computer in there.

> and organize purchase of the part and an repairer to do the fix.

Not only do I not need any appliance to do this, but

1) if they cared about parts and service, they could have a nice website for this stuff, and they don't. So judging them based on that, this will also be neglected (after being marketed.)

2) this would really be a way to prevent people from getting parts who don't have a current service contract, and to screw them on the prices. It would also be a way to take a huge cut from the repair companies who participate in the program, who would also be large rent-seekers (who could make a deal with device manufacturers to be included in the software) skimming just as much by farming out the work to subcontractors.

End result: single thing goes wrong, repair and parts cost more than the device. Don't worry, they're running a promotion that gives you credit towards buying their latest model.
Yeah we say that, and it does mean the general case of putting your kettle on to boil. It could mean stovetop or electric.

But for the vast majority of us it's electric.
You're right that this should get talked about, simply because it's the sort of thing that some people will wonder about. That said, I'm pretty sure "everybody getting sick all the time" has basically been the expected outcome of since about winter 2020 or earlier.

After the lockdowns where started, rates of non-covid-19 respiratory diseses dropped, and the flu in particular was a lot less common, dispite a poor flu vaccine and uptake. Ever since the winter of 2020, the doctors in my country have been warning us that the flus could be particularly nasty as people stopped social distancing/masking/etc.
Alas even today there is no RCT on masks. Why?

Countries and states with strict mask policies did not do better than those without these policies (see US States for an example).

So do mask work?

It is like a religious belief system, you would get the same reaction when questioning if God existed and asked parishioners and atheists. Everything is evidence for those that want to believe.

Studies that claim to "prove" that masks work turn out to be shambolic messes - yet are published in the most selective of journals, see for example:

This depends on the manufacturer. Some manufacturers make dishwashers that can utilize both hot and cold water and others only work with cold or hot water.

As an example Frigidaire, GE, KitchenAid, Whirlpool will only work with hot water; Samsung, Ikea, Beko will only work with cold water; and Bosch, Miele, Electrolux, LG will work with either.

Then your bet would've been lost. My father has been building custom alarm systems in the early 90s, before going fulltime IT. It was hard to get half a step ahead of him in tech news, even for a minute ;)

When exactly did this smart device thing turn bad? Maybe it's been bad all along? I refused to use a smartphone until 2014 or so. My first Android got Cyanogen within about a month. When I shopped for my first Roomba (recently RIP), I specifically avoided the WiFi models.

Nowadays the "smart" devices are almost unavoidable, so on my LAN, each one gets its own set of firewall rules (usually to block them from the Internet completely). If it can't work that way - it gets returned. I've also set up a host-based blocklist for ads/trackers, for the entire LAN.

It should not be this hard to protect your privacy, but the current trend is to make this impossible even for the power users. Right to Disconnect should be a thing.
> order me the cheapest best reviewed dry dog food that will arrive tomorrow

That's 2 continuous axes and one discrete option. What if the cheapest one is the worst reviewed? What if the most expensive one is the best reviewed? What if the middle price is only slightly above the worst review? What if there's a clearly cheapest, best option that is only available in 2 days?

How do you "trust" an answer to this? What does a single choice answer even mean?

I'm not sure I'd trust a shopkeeper to make this decision for me, as they could easily rationalise not telling me about the cheap and great option if it's not in stock, or falling more on the quality than the price because they make more margin. And Amazon is in this position on this one.

I can see a market for "Alexa, order me cheap dogfood for tomorrow", but pretty much anything more complex than that I just don't think people would give the decision to a biased third party to make for them, let alone a non-human one.
The strategy is to focus on the 600 enterprise companies that are responsible for 75% of their ARR & to cut marketing expense and R&D. Seems reasonable.
Exact same anecdote for me. I’ve been sick every two weeks, then one week recovered, and repeat for the past 3 months or so. I’ve been sick more in 3 months than in 5 years. It’s very odd. Never tested positive.

Pronounced, this would be "x at grade-down of count of each x" - and indeed, in "q" (a syntactic sugar for K that uses words instead of symbols), this is almost how you would write it (rather: "x at downgrade count each x". It's basically algorithmic math notation: In math you say "b^2-4ac" rather than "b squared minus 4 times a times c". In K you say "x@>#:'x".

It's not just a matter of symbol/syntax familiarity - there's also idioms, etc. But the "scariness" is similar to the "scariness" of a language like Japanese or Arabic, which uses different graphic elements, syntax, vocabulary, and idioms. You might not like it, but it's not because there's something weird or wrong about it -- it's just foreign.
