> tl;dr TLA+ is a lot more practical if you care about bug-free software

TLA+ is not generally used for end-to-end checking of actual program code, unlike Coq. Usually you build a simplified "toy" model in TLA+ of some architecture of interest, then use model checking to try and refute some claimed properties of that model. If the model checker finds a refutation of some property, then yes, that's a verified bug in your toy model. If it fails to find one, that's not a proof of correctness other than in very special cases where a property can be checked finitely.

So yes, model checking is helpful in some cases, but it's not a generally useful tool. And there are ways to do the same things in general proof assistants, e.g. by interfacing them with external SMT tools. The TLA language in itself is also unproblematic, it simply adds modalities for time, state and non-determinism to ordinary logic, and there are well-known ways to convert ("embed") those features to a form that a proof assistant can work with.

> xenophobia [...] unclean [...] technocratic adoration

That's some emotive language, and projecting viewpoints that I don't think represent the beliefs or thoughts of most Australians or New Zealanders.

> their leaders get to bask in technocratic adoration.

That you're saying this about Australia indicates you're not aware of the political situation at a state or federal level in Australia.

Governments at all levels have been criticised broadly and constantly over their actions (or lack thereof) in relation to the pandemic.

Overall the broad strategy of both countries is to limit the spread long enough to get the country vaccinated. The only way to effectively do that, is through zero-covid approaches. Oh, and by the way - the zero-covid strategy was only adopted by the States in Australia - the federal government didn't (doesn't) want that to be the policy, but the states forced it anyway.

These strategies would've been even more important if a vaccine took the 2-3 years that most experts were projecting that it would take to develop, produce and deploy an effective and safe vaccine.

For the most part, these strategies have worked, they've limited the number of deaths, the number of people in hospital.

This article is about each 100,000 COVID deaths in a big country. It’s a psychological number and since the last 600,000 cases, it happens to coincide with a new spike. I don’t think the average reader is more afraid after reading these facts.

This article doesn’t compare state performance. It’s not important to always compare on electoral lines, and it sounds like you want a different article. The NYT is covering this from a national angle; your county newspaper will be more relevant.
Well, they did write:

This makes sense. As a kind of sanity check, I thought about the Ebola reporting I've read in the past decades and cannot remember any reporting that used the proportion of population. I do remember Ebola reporting that described outbreak magnitude using absolute numbers of people, though.

I'm persuaded.

I am a mathematician looking for a collaborative environment in which to build tools and techniques for solving challenging problems.

I recently completed my PhD in mathematical physics: my thesis focused on supergeometric aspects of the Batalin-Vilkovisky formalism (used to quantize gauge theories such as string theories, etc.). Recently I have been interested in applications of mathematics to computing and data, such as topological data analysis and learning.

I have fairly broad interests, and although I do not have experience with software in a professional (non-academic) environment, I've been coding since I was a kid.

Please feel free to get in touch with me if you'd like to chat about an opportunity.
1. The key term is "per capita than the US". When we are talking about physical resources and climate change, per capita doesn't make much sense. If the US imports a million people, the US needs physical resources for a million people. Having more people already in the US doesn't automatically materialize raw physical resources.

2. You talk about per capita then switch to US having the most expensive military. Why not use per capita for costs? US is not the highest. Israel and UAE come before. It makes more sense to use per capita figures for cost.

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

3. The US is also above Iceland, Polan, Spain, Ireland,
Finland, Israel, Japan, etc. Why leave that out? This kind of bad faith discussion is really boring.

4. "the difference between the number of persons entering and leaving a country during the year, per 1,000 persons (based on midyear population)" It doesn't distinguish between permanent and non-permanent visitors. Also, it doesn't say whether illegal immigration is counted.

5. "In many of those countries, the "huge welfare states" have prerequisites ( for instance you can't just come in as an economic migrant and ask for unemployment benefits)."
Thanks for making my point! The US has few such restrictions.

And of course my original comment is flagged because we can't have free discussion going against the party line.

That's a rather privileged take. Businesses are people's livelihoods and even when insured, insurance doesn't necessarily cover all tangible and intangible costs, if it covers anything at all. Not to mention rate increases.

Property is an extension of person, because we spend portions of our finite lives turning effort into tangible goods.

The problem with the "human life is worth less than property" attitude is that there is always a contingent of the population which is not hesitant to take advantage of such kindness. Especially when you start mixing cultures. The only deterrent that such people recognize is the threat of violence.

This isn't justification for extreme punishment legal punishment, but it is moral justification for deadly violence in immediate response to ongoing theft of the output of one's labor. Otherwise you are sending a message that people are essentially free to take from you and your community, because arrest and prison are not a sufficient deterrent for some groups of people.

JavaScript is a language whose flaws are well understood by experienced developers, and those flaws are massive.

I also don't particularly care for "async everything" by default. It makes your program more difficult to reason about. Rather than dealing with concurrency in a subset of your application, you now have to worry about it _everywhere_. There are only a few classes of software where the async-everything approach even makes sense.

Throw in the fact that the ecosystem is an absolute dumpster fire and you have more than enough justification.

Most changes work better if there's a ramp or taper. Phasing out subsidies is a good idea and possibly worth doing in parallel but carbon fees will directly affect those industries in a very direct way so it kind of cancels out.

I'm possibly reading too much into your question but carbon dividends that let everyone spend the money raised on what they need to do to adjust are a sensible part of any plan. Taxes are a very useful and soohisticated government tool, and in America certain groups have relentlessly attacked both taxes and government intervention as things that are harmful. (The exact same people arguing that tobacco, global warming, lead paint, corporate funding of politicians etc. are not bad for you)

>> such as, reversibility, legal protection and customer support.

Most crypto holders just want digital cash...not another paypal. We already have paypal. I don't want "customer support" when I put my cash down...neither reversibility or "legal protection(whatever that means). There are legal agreements that can be set for different types of transaction but I definitely don't want paypal, visa or some random bank to decide whether it likes my transaction or not or put it on hold for "my own protection".
I'm very tired of Covid news but upvoted this because it's really news about bullshit in media, which is endemic of its own accord.
> What's the argument against researching it?

It's a diversion. They're all stopgap measures with no real long term application. You can paint all the road white and add artificial clouds, if you continue to live like resources are unlimited and pollution isn't an issue you'll sooner or later hit another problem.

If we don't take care of the root cause we're bound to fail. Unlimited growth and exponential energy usage isn't possible in a closed system. All these new "green" economy, "green" growth, &c. are perpetuating the idea that we're going down the right path and simply have to tweak a few variables to go from "catastrophic failure" to "idyllic paradise"

I don't think people truly understand how fucked we are and how deep the problem runs. https://www.youtube.com/watch?v=s254IPHXgVA

The advertising doesn't simply need to affect your personal preferences to affect your buying habits. If you were buying a few different packs of soda for a group of people (e.g. for a party), how much cheaper would the case of Pepsi need to be than a case of Coke for you to buy it instead? Could that be affected by advertising that made you feel like, regardless of your personal affinity for Coke, Pepsi is the acceptable default choice?

Imagine further that this isn't a product category that you feel quite so strongly about (most people don't have a 4-deep ordered list of brand preferences for common product categories). If you were making a quick choice between Sprite and 7-up (again, for a party), are you sure that advertising couldn't possibly influence which of the brands is most accessible to your brain?

There seems to have been so much fraud in crypto. It's a space that seems ripe for grifters.

The craziest story (which sounds a bit like your guy) I encountered was that of Shaun MacDonald [1], founder of two crypto companies called BCT and CG Blockchain. A company I worked for signed a business deal with BTC before they went under in 2019.

MacDonald was later revealed to be a convicted Canadian white-collar criminal with the unlikely name of Boaz Manor, who had stolen millions of dollars from hedge funds and who appears to have absconded with millions worth in diamonds [2] (!).

BCT/CG Blockchain turned out to be a scam, too. [3]

There is a lot of research aiming to produce strong, non-opioid pain killers from venom peptides, from spiders, centipedes, sea anemones and other creatures.

These peptides have an action on sodium channels, specifically Nav1.7, so the article doesn't seem particularly surprising (although the article was from 2012, so it might have been back then).

We already have several drugs that work on sodium channels, but they are non-selective, and there are several sub-types of sodium channel with different uses - such as regulating heart beat. The challenge, is to produce a drug that selectively blocks sodium channel Nav1.7 - the idea being that this will reduce pain while not affecting your heart etc.

I suffer from chronic neuropathic pain, so I've been somewhat following this research for a while.
The stock market is theoretically supposed to be efficient, but these days plenty of individual investors are about "the mission" of companies like Tesla, throwing money at shares regardless of any fundamental analysis. I'd imagine Rivian will attract plenty of similar investors, and it'd be kind of silly for Rivian not to take advantage of that opportunity to raise easy money.
Oh I have done this many times, when I said I've been studying this clip I really meant it because I truly want to hear it. LambdaComplex also mentioned tapping foot and counting and suddenly the count should change.

The result of my many experiments is that it is super hard to count 1 2 3 4 when they only clap twice. Most of the times, within seconds, I'm 'rhythmically' counting claps. Be it 'one three one three' or whatever numbers I chose, but the number only changes with the next clap so, well, that won't work because the audience doesn't change how they clap and I'm only using two different numbers.

I'm forcing myself hard to count to 4, basically saying another number in-between claps and if it works for an extended period of time I'm so focused on keeping my own momentum and keeping the 4-count going that I don't even hear the music just the claps and I try to remember to say the other number in between 1 and 3. That also absolutely fails because I'm already checked out of whatever I'm trying to hear

I also did experiments with my friends and some of them just hear when it happens without any counting or whatever. So I tried that as well - I would listen to this with my eyes closed and mark the point when I thought the clapping has changed. I think the results were statistically as good as my internal approximation of how long 40second is until I learned to hear the exact part of music I have to hear before I say 'yeah, it's that' - but it has nothing to do with my understanding of it.

It may be of interest that even in classical music there are occasional exceptions to the normal GDAE violin tuning. In Mahler’s 4th symphony the violin solo is played on an instrument tuned to AEBF# which gives it a very distinct quality.

For a really large country like USA, state-level data is more accurate than country-level data when it comes to evaluating length of epidemic spikes. It is conceivable to have rolling spikes that affect different states at different times, but when summed up give the illusion of a never ending surge. County data is even better, but it's harder to assess at a glance, probably more prone to cherrypicking.

The capitalized quotes are from the article itself. I'm pretty confident they are fearmongering the specific point that delta is super hyper dangerous for young cohorts.
I grew up in a city with a major Glock factory and a thriving gunsmith industry, with every other person being a hunter. My father showed me how to shoot when I was 10.

The idea that the unique problems the US has in with guns are a simple result of the numbers of gun owners is wrong. There are tons of gun owners in the Alps and in Scandinavia, and not a single region has comparable problems. Over here if at all guns are usually used in suicides and domestic murders, someone robbing you at gunpoint is so rare that it is newsworthy.

I'd say this has more to do with how we deal with poor, sick and/or criminal people than with the existence of guns.

Have to jump in on a TLA+ comment, especially one about how it handles “types.” I say this all over the Internet - the way that TLA+ handles types is the absolute ideal from the programmer’s perspective - there is nothing special about them! No special syntax, semantics, nothing. It’s all the same language and logic, unlike most type systems which have a completely separate type language with subtly different semantics.

The problem is, that programmer simplicity pushes the complexity to the type checking. You can’t statically check TLA+ types, you have to model check them which is much more intensive.

Maybe there’s a happy medium.
Datacenter networks are an entirely different beast to SME and SOHO business networks. You don’t get the same budget for nice equipment, nor dedicated IT persons to run it, nor any remotely technical people on the ISP side to help you. SME and SOHO are very price conscious too. Think low margin retail and petroleum and fastfood.

> You cannot do this with IPv4 either. Routing has to work. It works for both IPv4 and In But if you are saying, you add 2-3-4 layers of NAT, this is just crazy.

Yes, you literally can stack a dozen commercial IPv4 firewall/routers behind each others networks and a PC plugged into the very last one will have no problems access Google on the browser. Because of NAT, which all IPv4 capable personal/SOHO/SME routers do by default.

Sure, VoIP may not work, but actually chances are it will because the VoIP service will be NAT-free via VPN to the provider.

And in this retail/petro/fastfood environment things like p2p file sharing are irrelevant and not required. All traffic is either to websites or to corporate systems across VPNs where NAT is not present or easily managed.

> By sending RA and expiring the old prefix on the failover. I admit, this is not an obvious solution and it may not be suitable for some edge cases.

It’s a slow failover by comparison to IPv4 methods. Too slow for some common use cases in industries I deal with. It also doesn’t allow for load balancing across links (eg route all important traffic out link 1 by default and all backup uploads out link 2 by default).
