That is roughly accurate for describing the operation of real compressors.

The reason for calculating the bare minimum "magic compressor" cost is because it also applies to techniques like pressure-swing adsorption:

https://en.wikipedia.org/wiki/Pressure_swing_adsorption

Using PSA can reduce the energy cost of CO2 extraction significantly relative to direct compression technology. But because we know that the adsorbent is used in a cyclic process, we have dW[compression] = p dV + dE[adsorbent] and the long-time integral of dE[adsorbent] is effectively zero because the adsorbent cannot absorb or release energy forever, so ΔW[compression] = int[p dV] and thus any technology, compression-based or not, incorporating some finite amount of external components, is subject to the work limit.

This is also why, for example, thermodynamic analyses of engine types are always concerned about the possible compression ratio. You could consider the partial pressure of atmospheric and stored CO2 as the compression ratio of a hypothetical compressed-air motor, which can then be run to extract thermal energy (i.e. violate the second law of thermodynamics) from any process more efficient than 500 J/kg CO2, since again W[motor] = int[p dV]. You can improve the compression ratio by taking advantage of the P-T curve and performing the whole compression at the South Pole, which saves you about 100 J/kg.

Also, I was off by a factor of ten when I plugged in the vapor pressure of CO2. Correcting this is left as an exercise to the reader.

Technologies not subject to the work limit include e.g. olivine crushing, somehow inhibiting volcanic activity (???), planting trees, etc. Another technology I just thought of would be to to form CO2@H2O clathrates in seawater starting with air, which would also lower the compression ratio, and extracting the (solid) clathrates to recover CO2 and desalinated water. Here the pressure required is much lower and additionally desalinated water is produced; this only works if we form the clathrates in a cold environment and decompose them in a warm one, which is kind of inconvenient. Then again, shipping gigatons of fresh water to LA might become necessary anyway!
I was expecting to see https://en.wikipedia.org/wiki/Avedis_Zildjian_Company for USA. I suspect there is always some wiggle room in the definitions of "oldest", but wikipedia dates it as earlier than Shirley Plantation (and it is also older than the company given for Armenia).
The best way to prepare for COVID-19 is to already be prepared for a wide variety of civic disruptions.

Have enough food and water on hand to shelter in place for up to 2 weeks. Never let your gasoline dip below a quarter tank. Have some paperback books and candles on hand. Have some duct tape and plastic drop cloths. Keep some camping gear. Practice not panicking. Keep a bottle of plain, unscented bleach on hand, and practice diluting it to 10% of the bottle concentration.

If you don't already have supplies specific to COVID-19, the desperate and the hoarders have probably already snapped up what you might want, and the opportunists reselling it at a 400% markup.
ime a lot of the ease of pattern recognition and recall comes down to interest. It's likewise easy for me to recall how and why a 302 differs from a 351 or a 460 but I couldn't tell you which letters proceed/follow 'j' without sounding it out in my head.

My solution has just been to fake it, if I can convince myself e.g. that my neighbors' names and faces are interesting/important than remembering them becomes almost impossible not to.
Can you clarify on which orthodox church? Greek, Russian and Ethiopian all come to mind, but I'm not aware of a general middle eastern one (genuinely curious). Perhaps it wasn't called orthodox back then (prior to 300AD)?
> You can stop math. Legally stop fb from using E2EE. You’ve stopped math. You haven’t stopped some people from using it. But you’ve prevented common people from having default usage of that math.

No, you haven't "stopped math". You've enacted a law and stopped Facebook from using end-to-end encryption.

Math is universal. Math is something that should never be outlawed. Math is a fundamental right, an irrevocable truth based solely in fact. You can sooner stop alcoholism by outlawing alcohol than you can stop encryption by outlawing math. The idea of outlawing math would put us hundreds of years behind today; to enact a truth based on the church's "do this because I tell you it's true" instead of "understand this for yourself, I cannot tell you what is true". Outlawing math is dangerous and I cannot believe you are trying to make such an argument in good faith.

> Find a better way.

I do not believe there is a better way. You don't understand the math behind it. Instead of even trying to understand the math which is already widely understood by many, you instead want to make that math illegal and create your own. You don't even want to spend the mental effort to do that much: you demand others to do it for you.

> Two parties or three parties; three doesn’t have to be significantly more susceptible than two

This is factually false. The third party is a moving party which changes every moment. You can not meet that and still be "secure". It is antithetical to the very notion of encryption.

Thanks for your thoughtful comment. The Show HN link I submitted was the landing page of a small SaaS app that I have developed. Good advice on putting up a blog post - I think that makes a lot of sense for a regular submission to HN, but for a Show HN it seems that product landing pages is appropriate/expected. I think if my next attempt gets no traction, I will do a blog post. Cheers.
Repost as it didn't gain any traction. Should be fine if I read the FAQ correctly!
It's different because it's not actually setting a specific style, it's still a semantic description. You would never need to update all the "text-sm text-gray-700" in your project to something else, that just wouldn't make any sense. You might change what "text-sm" and "text-gray-700" (I'd probably go with a more meaningful name for colors, "text-gray-primary" or whatever, but hey) actually do, but you wouldn't want to actually modify all of those to be new classes at once.

In fact, I think this scheme is a whole lot closer to what most developers actually want, which is to have composable classes that actually represent something semantic. "text-sm" is your small text. That should be consistent around your application. If you change what some of that looks like, you probably ought to be changing all of it. If you want a few elements to use a different text size, then go change the classes on those.

I really encourage you to try this out. I was somewhat skeptical, but it truly feels like a huge step forward. Going back to something like Bootstrap/Foundation or- God forbid- BEM feels incredibly painful to me now.

I also don't think separation-of-concerns is a reasonable goal. I read this article [1] after using tailwind for a while, and I agree with almost the entirety of it.

This is an area where 'fine' rapidly becomes problematic.

Remember that the dataset is often going to be small, and frequently will contain known or easily guessed strings. Uncompressed, often at predicable locations.

There are whole classes of cryptographic vulnerabilities which might result from either not compressing (compression should in theory would normalize entropy over the stream) or using a compression algorithm that results in a predictable dictionary, length, or other value in the same location (if junk padding isn't used properly).

Also, sending the state from client to server might open replay attacks and all sorts of other horrid situations.

Security depends on doing everything correctly all the time; this context IMO just feels open to too many plausible and unknown (potentially introduced in the future) vulnerabilities.
> The Valley is now the new East Coast people, the new Madison Avenue. Doing a hard startup in the Valley now is like trying to start Intel in 1960 New York. Hard startups are hard enough, without trying to do that.

I think places like Detroit are promising for this. Lots of cheap real-estate, a local history of technical skills, and serious problems to solve (urban farming for example).

Also due to the internet age, developing nations are also pretty promising for their lack of regulation, and extremely cheap location. But have other serious problems (like availability of smart trained talent).
Gitlab Unfiltered[1] is pretty cool. Say what you want about Gitlab, but they go hard on the openness aspect of things. I can't think of another company that is on the same level as them - streaming meetings and other stuff on Youtube almost seems like overkill.

I'd imagine a reusable React component something like:

<Alert type="danger">

</Alert>

Of course this solution would work in other templating engines as well.

The alternative would be extracting css components:

}

.alert-danger {
@apply bg-red-100 ..
}

He made himself available for questioning _after_ sequestering himself in the Ecuadorian embassy, and offering to do it in a way that was satisfactory to him - _not_ when the accusations were made.

That is... false. Trading down consistently only works if you’re playing with idiots.

Trading a high value property for a low value property makes sense if you get a color set, but if you do this multiple times with bare minimum competence players, the likely outcome is that everyone has at least one set, but you have booth the lowest amount of cash to develop things and the least valuable properties.

With the exception of edge case (although often optimal) strategies where you lock down the available houses, trading down is likely a sign that you’re trying to increase your likelihood of winning from 0% to 10%, while improving the odds to a greater degree for whoever is getting the better deal.

Most properties are superficial until they have specifically 3 houses on them. If you have three color sets, but fewer than 3 houses on any of them, you’re going to lose.

In the early days, Facebook logged into user's email accounts and stole contact information without users' knowledge or authorization. This was possible because people used the same password for their email and Facebook, a practice common especially back in those days. This is one of their sources for PYMK.

In fact Facebook has used this technique very recently too:

A security researcher noticed the tech giant was prompting some users to type in their email passwords when they opened an account to verify their identity. And after they were caught... Social networking giant Facebook said on Wednesday evening it may have “unintentionally uploaded” the email contacts of up to 1.5 million users on its site, without their permission or knowledge, when they signed up for new accounts since May 2016.

Not every game has a message. Settlers of Catan was created to show what a fun, tight boardgame with some depth and a limited playing time would look like, and kicked off the German boardgame boom as a result.

No encryption algorithms would be "banned" by the proposed law. Rather corporate service providers would be compelled to act as bona fide MITM, regardless of what primitive(s) they use.

Once we're past the point of users doing something beyond downloading an app from a corporate app store, all secure encryption would be back on the table.

Of course we can foresee a true ban on encryption some years out, but at that point XOR has the exact same signature as AES. Steganography is the corresponding approach for that attack.
> I’m trying to understand how big a problem it is to read PDFs on mobile.

The "simulated sheet of paper" aspect of PDF's make them a pain on anything with a screen size smaller than needed to show the whole "pdf page" at a readable size to the user at once. On anything smaller one has to zoom and pan around.

However, you can see for yourself. Assuming you have a smartphone/tablet, just install a PDF reader if it does not already have one [1], then start viewing various PDF's.

> Personally I’d prefer viewing a responsive and accessible HTML version instead of having to pan and zoom the original pdf.

I'd love to know how they got the power consumption down so low! 28microwatts when active, that's really something.

Some maths: 0.000025W.
A typical AA battery is 1.5V / 2Ah (https://www.powerstream.com/AA-tests.htm).
1.5*2 = 3Wh.
3Wh / 0.000025W = 120000 hours runtime.
= 5000 days = 13 years, off a single AA battery.

That can't be right? That's incredible if true.

I don't think this is exactly comparable to a theme, but I do agree that it's priced too high.

Not only that, but I think the pricing model is wrong; lifetime access for a one-time fee is a big mistake (and one I previously made with a startup).

As a developer, I understand that you need a predictable, repeatable income stream to keep going - and if I'm going to invest in something like this, I want it to keep going. I'd far prefer to pay something like $49/y instead of a one-time $249 fee.
The micro funds as listed in this article seem more like a replacement for angel rounds or almost as scouting fees to bring deals into traditional VC funding structures.

That (to me) is less interesting than the work that's happening with TinySeed, Earnest Capital, etc. where they're trying to hit bootstrapped companies with a little bit of traction but that are unlikely to become unicorns.

> Yeah, I once played with someone whose strategy was "Never trade".

That's the right strategy for strong play. You should never trade property for mere money. If you absolutely have to, trade property for property if the trade gives you a monopoly, or if (in a more-than-two-player game) doing so gives you a net increase in the number of groups for which you hold at least one property (so you can block anyone from getting a monopoly in those groups without trading with you).

It's not an especially fun strategy, either for you or the people you're playing with.
I believe it's something more to do with the OP's (mistaken) idea that CS majors are somehow more likely to be "hackers" or people who exchange pirated software or wares -- when really there's only a handful of people who know how to crack the DRM in the first place (which requires some degree of technical know-how) and then those people distribute the pirated goods to others (whose technical literacy may be far less, even if it's still enough to distribute the pirated material on down the line).

It's a bit like thinking all painters are in favor of graffiti, or all musicians are okay with "sampling" and remix culture.
