I don't want a tall cat food can. we feed the cat out of the can, it can't reach the bottom of a tall can. Also, if you don't feed out of the can, now you have to store half a can of wet food in your fridge (ew).
If you imagine cutting out rectangles from sheet metal, you can completely tile the plane. Punching out circles, you'll use a maximum of roughly 91%. So I imagine the more of your material you use for the sides, the less scraps you'll end up with. I'm sure the problem is a lot more complicated than this though, with deburring, corrugation and whatnot.
"Most cans" you see there are the small ones. But as the quantity grows, it is the height of the can that grows, and not the diameter.

The two are complementary. In particular, PBT can be used to generate new minimized inputs that kill mutants, without the need for a test oracle to say what the code should be doing.
Historically, when the truth suffered to that extent the world was being set up for war. And afterwards we always pledged to do better, but we never really do, the cycle repeats with a high degree of reliability.
A while ago, I noticed that the bread I eat sometimes had the twist tie twisted clockwise and sometimes counter-clockwise (annoying since that is the direction it should untie). I called the company to ask why and they left a message with an explanation. It wasn't a great explanation, but I was impressed they responded. They said that the breads comes off the conveyor belt and are routed two ways and the twisters are different.
Yes! I think one of the most fascinating things is that I believe they are allowed to create a nuclear facility if they want?

I don't think it's productive to speak of the LLVM maintainer's decision as an abuse of power. The actual revert happened in contradiction of documented LLVM policies (which, according to the maintainer, do not match actual LLVM policies), so I did take issue with that, but the maintainer wanted to first make sure clang had a different conforming extension that Chromium could use instead before removing the non-conforming extension, and assuming that a non-Google project would be given the same treatment -- and I have no reason to assume otherwise -- I think that is defensible. The change was <https://reviews.llvm.org/D91913>, addressing a conflict between GCC's ,##__VA_ARGS__ extension with the C and C++ standards in the corner case where a macro, let's call it FOO, takes no named parameters and is invoked as FOO(). In standards-conforming C modes, clang already acts as required by the standard, but in meant-to-be-conforming C++ modes, it does not.

Awesome, what I'll do:

- Read the style guide (optional watch the video)

- Skim LevelDB and Chromium

- Skim the awesomeopensource.com list

- Not learn C++20, your argument makes sense. It'll be fun water cooler talk when I happen to meet other C++ programmers, they can teach it to me for fun :P

It definitely helps!
The first part is interesting but the section "Checking My Privilege" is really virtue signaling looking for a problem.
Amazing how we have these stark examples of the obvious dangers of aggressive moderation to enforce a party line (sorry, I mean "to combat disinformation") and it just doesn't seem to register at all. I'll bet it wouldn't even be hard to find people who say that banning mask advocacy one week and mask skepticism the next was the correct thing to do "because the available information changed."
Having read the pdf, I was underwhelmed. There doesn't appear to be any meat here, merely restatements of the obvious.
When teaching TDD a strict adherence often is appropriate to help learners develop good habits. But like many such rules experts get to break it, because they have the expertise to know when it's appropriate to do so.

Ask HN: Is there a standard for building platforms that host apps
Hey HN!

I am joining a team as CTO to build a web platform that will eventually host apps built by third-party developers. I plan to build the first-party applications as though they were apps hosted on the platform as well.

To this end, I was looking for some reference architectures or standards. I wondered if there was a standard like Matrix[1] or a methodology like Twelve-Factor[2]. Any pointers would be very helpful!

The stack I'm planning to build with is: React, Elixir, PostgreSQL, AWS.

Excellent callout to that thread, I'm surprised it didn't get more traction. One of the more interesting pieces (or rather, maybe a letdown that this isn't so novel) was a reminder that Florida (and likely many other jurisdictions) has done something similar with Disney many years ago - even giving permissions to create a nuclear plant! https://www.forbes.com/sites/jamesconca/2019/02/21/disney-wo...

It is certainly fascinating. However, I don’t think Nevada needs to transition away from existing industries so badly that it’s worth allowing governments of unelected boards and directors to run localities.

I didn't forget you guys, thanks these are all great and added to my combined playlist of radios. I didn't get around to CHIRP until this morning and was greeted with some Sisters of Mercy love as soon as I tuned in, that's a win right there. :) Much appreciated for pointers.
Edit: Disregard this. The other answers are better.

I guess it's because of the fat ends - if these have constant thickness, the volume will only increase as diameter changes.
I clicked through to the Twitter thread, and the examples of removed videos seem to be people dancing in their underwear. Does Tiktok allow that in the first place?
My first thought was for the ends, and for a similar reason that the smaller diameter cans pack more densely.

If you're punching circles out of sheet metal, you'll get more waste with larger circles.

As an (European) outsider: Manufacturing consent is a key feature of societies. If societies are not just an accidental aggregation, but do have some actual cohesion, a core body (canon) of shared believes and opinions is absolutely necessary. If a society fails to manufacture consent as a common point of reference in this core domain, we may even speak of a failed society.

A certain amount of mis- and disinformation, manipulation, falsely raised expectations (e.g., if masks do not stop CV19 dead in the track, it's also not a viable tool of mitigation), etc, is to be expected. A certain amount of dissent is vital to a thriving society, as opposed to a slow descent into dogmatism. A certain amount of dysfunctionality is actually functional to societies. However, if we are losing a common point of reference and the discussion turns from an ever varying problem space towards questioning and problematizing consent per se, society itself is at stake, as partitioning and claims to rightful dominance by one side or the other are inevitable. Dealing with this is not a matter of free speech, even, if suppression of free speech may be empirically observed as an – mostly failed – attempt to address this. It's actually more connected to the question, what speaking freely actually means: Is it to enter into or to contribute to a discussion, or is it a means of claiming dominance? In other words, does the address include those who do not share the specific set of believes and points of reference of the speaker, or does it exclude and/or ignore them, by this turning into an hermetic or even radical argument, meant only to augment the position of the speaker? Is it still pervasive, or has this turned into a hegemonial discourse? If it's the latter, it's not about manufacturing consent anymore, but about establishing a new, biased one, probably by force.
Well the current debate is not on Masks: yes or no//

But more do you need 1, 2 or 25 masks... Do you need to continue to wear a mask after vaccination... Are masks now a permanent mandate for all of time....

> I'd be surprised if there weren't a fight from the feds about ceding this amount of power to a state.

Huh, I had exactly the opposite reaction. Ceding what amount of power to a state? The article says a company would receive the same authority that a county government already gets. That's authority the feds never had; they're not losing anything here.

Which kind of defeats the purpose. How is it a charter city if it's still subject to all the same laws that it would be if it weren't chartered? The Lübeck model wasn't based on being allowed to staff the courts -- it was based on being allowed to write the laws.
It's important to remember that federal governments have imposed the Bill of Rights and federal laws on company towns during the 19th century. Now whether the same will happen nowadays I'm not too sure - company towns did not have good reputations in those days...

I think we're going to have to agree to disagree if we can not begin to start out from something as axiomatic as what a fact is. A fact is something that is observably true, and no matter how many people believe something that isn't true doesn't make it a fact. It just makes it a wide-spread falsehood.

Democratic institutions and free speech are both great goods and very fragile. They also both have the core capability of destroying the other, which presents us with some considerable difficulties that I do not think will be resolved in my lifetime or that of my children, simply because I do not believe humanity to be mature enough yet to recognize that the powers that divide us are endemic and would need serious attention first if we are to overcome this particular barrier.
I got heavy into tracking personal data after spending a week in a cardiac unit in July 2017. My own tracking efforts have lead me to the absolute best physical shape I have ever been in.

My weight went from 340 pounds (hence the cardiac unit) to 160. I have gotten into ultramarathons and lately, triathlons. Strength wise, I managed to drop 180 pounds while increasing my strength.

It is amazing what the mind can do if you prime it with the right kinds of metrics.

A single atomic electron state will almost certainly switch to a problematic degree except for very exceptional materials in typical room temperature type conditions - free ozone, UV light, background radiation. most crystals will grow or change at room temperature in some way over time (normalizing to the lower energy state if they weren’t 100% already, or high energy perturbances like UV light damaging the matrix and then ‘falling down’ the energy ladder again). Diamonds ablate through oxidation as well.

Error correcting helps of course, but we already have to do a LOT of error correcting to make even the ‘low density’ spinning rust drives we have now work. At some point you have so much noise, your error correction overhead is too high to make it worthwhile - which is the current issue with high q-bit quantum computers for instance

We’re a long way from having the materials science to be able to do this. Same issues plague quantum computing. Maybe some day though?
I grew up in a house with a left-handed dad and sister. Half the time, the twistie was 'the wrong way' and in opening it, I'd instead twist it into a hopeless knot.

Education isn’t an answer. It’s good and we should as a society optimize for it, but it’s vastly overrated. There will always be cognitive differentials. Educated people are easily duped by uneducated conmen and putting people in a classroom for more of their young adulthood won’t change that much at all. And don’t get me started about “re-education” camps. It’s great to have an abstract one size fits all cure for the ills of society, but “education” is not the panacea people like to pretend it to be.
Thanks for the context! You saved me from foolishly wandering into crowd-with-pitchforks mode.

Academically, a virus is a kind of parasite, one that cannot reproduce (or really do anything at all) independent of its host.

All “parasite” means is that the organism depends on a host, but yes outside the academy it is often used in place of “multicellular parasite”.
Ask a random non-STEM PhD about truth, virtue, or morality and their sneer will say it all.

This article captures it well, but when you look at where the culture is, it's too late. The whole discussion of tit-for-tat ideological accusations and talking point exchanges misses the forest through the trees. I think we're past the inflection point. There is literally a massive volunteer army of people engaged in popular deception, who have by merely adopting certain beliefs and attitudes declared themselves enemies of discourse and truth itself. They were trained in western universities to become activists posing as experts to advance the values, agenda, and powers of bureaucracy. There is almost no discourse left, there is only litigation and war of all against all.

Maybe it's still in the "honeymoon" phase in the west, but I'm surprised TikTok hasn't attracted more, uh, Twitter opprobrium over stuff like this:

> The Intercept published internal documents from TikTok instructing moderators to limit content showing users who were “obese” or with an “abnormal body shape,” who had “ugly facial looks,” and who appeared in front of “shabby and dilapidated” environments. TikTok’s response was that some of the guidelines were initially intended to prevent bullying but were no longer in use when The Intercept published them. The documents, according to The Intercept, made no mention of bullying.
Agree absolutely. It also reminds me of, “For every complex problem there is an answer that is clear, simple and wrong.”

I don’t know how people have the ego to think they’re going to study a problem for an hour or two and discover solutions that have eluded competent people that have spent their careers studying the problem.

Every volume contains only a certain amount of potential free energy that can be used before the end. That’s what you fight over. Dyson Spheres, fusion, antimatter, these are all details. Everybody wants negentropy and it’s a zero sum game.
I would say your risk in taking a homemade vaccine is greater than your risk from Covid if you don’t take the homemade vaccine. The homemade vaccine is unlikely to work so it won’t decrease covid risk much to you or others. The expected value is low.

It seems like it’s probably more likely to harm you, either directly because you’re shooting amateur-made chemicals up your nose, or indirectly because it might give you false confidence or make Covid hurt you more if you do contract it.

It’s an interesting idea to make your own vaccine, but clearly a bad one.
The fun thing is that if you have biased moderation removing lies from one side it means that almost all lies people will see is from the other side. To me it seems obvious that this would cause people to distrust that side, since in their feed almost all liars comes from that side.

So really I don't think that this kind of moderation helps.
You might be able to get a response like this today if you mention the brand on Twitter - that's usually a more marketing-oriented support channel.
It's looks like this is an open source science project originating near Boston. The white paper looks pretty thorough. I think they progress by means of people contributing back with their findings.

https://radvac.org/

I think the reason they're (clearly) not first is because it appears they had to scale their people-network as well as actually work on the vaccine. It doesn't help that biology and genetics skills are -as yet- a bit more rare than programming or editing skills yet.

Given the constraints I think they've gotten impressively far within 1 year.
First I thought "Nevada Bill" was the name of a gunslinger.
That's not really my strong side...

But a quick search brought this paper to the light which might serve as a starting point: https://res.mdpi.com/d_attachment/energies/energies-11-01381...

For example they report on a project where they used photovoltaic panels to stabilize changing power consumption in a power grids with minimal changes in the existing structure - something that is hard with traditional power plants since they basically have to much momentum for quick switching action. https://ieeexplore.ieee.org/document/7007647

Also, agent based simulations (building on the idea of self organized criticality) are a thing. With these setups you can test power grids on their reaction for certain failure types - something you don't want to test in real life. I assume these simulations would also be quite accurate since consumption and production should be well known, as well as the physical properties of transmission.
Charter cities maybe a new concept in the US but they have been around for a while in places like India.

> However, if we are losing a common point of reference and the discussion turns from an ever varying problem space towards questioning and problematizing consent per se

Do you have an actual specific example of this happening? I can't think of a single time I've heard someone say "I refuse to agree with the prevailing consensus simply because" as opposed to "I find the prevailing consensus mistaken in such-and-such ways and so I disagree with it."

It is true that there are optical discs that will survive for a long time, because the plastic coating of the metal has a low enough permeability to the oxygen from the air.

The problem is that as an individual, it is impossible to guess whether the discs that you have bought are good and they will last 50 years or they are bad and they will last only 2 years.

There have been many published cases when the lifetime claims made by manufacturers were proven to be false.

The reason is that it is difficult to control the permeability of the coating during production. While many discs may be good enough, there are also many that will have a short lifetime.

The risks of storing data on standard optical discs are too large to be acceptable. There were special archival-quality optical discs with gold reflective layers, e.g. made by Kodak. Those could really be guaranteed for 100 years or more, but they were too expensive, so they were discontinued.
