The biggest current (last couple of years) price rises have been in Bitcoin, which is over a decade old now. Since it has been around so long, but the price is still going up a lot, presumably that is happening because of "tangible useful applications". So what are those applications? As a currency it has stalled, not least due to price volatility. Despite occasional bursts of announcements of retailers accepting Bitcoin, the number of retailers actually accepting Bitcoin remains very small, and often quite niche. Bit coin is not taking over as a currency. How about Bitcoin as a means of fast, easy, cross border money transfer (remittances). In the early days of Bitcoin is was widely touted that Western Union was going to get crushed by Bitcoin. It turns out Western Union is doing just fine. And over the major money transfer corridors WU fees are often lower than Bitcoin. Other major remittance agencies are also doing just fine using traditional methods. If any service is getting squeezed out of the remittance industry it is crypto ... fees can be larger, money often still needs to be exchanged from Crypto to local currency with all kinds of associated other costs, and so on. How about "digital gold", a hedge against inflation? It is not clear Bitcoin is really doing any better here, and assets and investments to hedge against inflation is a pretty huge market; Bitcoin has very limited appeal over all the other options available. So again, what are the magical tangible useful applications that make Bitcoin so very valuable? It's been a decade, but there still isn't anything to show ...

The first mistake is evaluating bitcoin by its "price". Assuming the key is that it is a currency the real question is the volume of actual transactions going on in bitcoin.

What is the amount of good purchased with bitcoin? It certainly isn't huge. How about remittances? Money transfer was one of the big use cases. It turns out that, despite a lot of hype and years to make a difference, bitcoin in particular and crypto-currencies in general, have made practically no dent in the remittances market. How about total volume of transactions? That's certainly higher, but how much of that is speculation trading based on the price of bitcoin? Hard to say, but surely we would see higher amounts of goods purchases and remittances if it really mattered.

So, instead of looking at prices, if we look at utility how is bitcoin doing? It's been a decade and it still hasn't had any significant uptake as currency -- not on any scale that justifies the hype anyway. Might it still be useful and gain traction in the future? Sure, it's possible. But the outlook isn't that great.

Me: Hey boss, I want to do a demonstration and then a press release about cyber vulnerabilities in cars. My plan is to use this Hyundai and show how I can change the radio from AM to FM.

Boss: boring. nobody will read that. Can we make it a Tesla?

Me: Well sure, but then we'd be demonstrating something that is not really relevant anymore and we'd have to find a car that was prevented from getting any updates which they generally do automatically...

Boss: No problem, I know a guy at a junk yard who recovers scrapped Teslas and fixes them and prevents getting updates.. Still, I don't think this is really going to be eye catching enough. I mean there are lots of stories about cars being hacked.. Can we spice it up some more?

Me: Well, I suppose we could say something about a drone

Boss: Is a drone required for this?

Me: No, but it will sound cool.

Boss: Great. Still needs something else.

Me: We could call this old irrelevant attack "T-Bone" to bring forth imagery of a horrible car crash.

Boss: Can this attack be used to create a T-Bone accident?

Me: I guess not really..but maybe.

Boss: It's a go!

I am not saying that this is not interesting - doing a test like this to 'demonstrate' something that is well known and patched is a semi-publicity stunt....it does work..so there is that.

You've stolen my childhood.

To be fair many of the rules and regulations did develop to make investors safer, or keep stability (just look at the fraud, shading messes and instability that has occurred on some of the crypto exchanges, especially in the early says, when there were few if any rules or regulations).

The problem comes from the fact that the big players have full time jobs and and billions of dollars to pick apart the rule book, split hairs, find loopholes, and dodge enforcement, so that, one way or another, the rules don't apply to them. The little guys, well they have actual jobs, no time, and little money, so they have to just follow the rules.

The other part of the lag in death figures is reporting lag -- it takes a while for death certificates to be filed, numbers to be collated at the county and then state level, and finally passed up to the CDC and other organisations tracking such things. In practice that can be anywhere from several days, to a couple of weeks and varies state to state. All up that probably adds another week of so to the lag, but with pretty high variance.

If we can manage to have options of Chloroquine, Hydroxycloroquine, AZ, Zinc, and one other treatment then I pretty sure I can put together a full controlled trial of the various combinations and find at least one that comes back as helping with a statistically significant p=0.05. This assumes, of course, that one skips the slightly more subtle multiple-trials Bonferroni statistical corrections, but that would be easy to do (its subtle math, and who really knows that much about stats anyway). If we can manage successfully produce a wide-scale controlled trial with positive results (and with 5 options and all combinations thereof, odds are that we can), I would be unsurprised to find a large amount of anecdotal evidence in favour of it, especially if you add in a little subjective validation, and extra attention paid to these particular drugs.

Data breaches like this will one get more common with the scourge of Climate Change.

Put down the gun bully and we'll talk. Stop telling people they have to wear helmets or you'll lock them in a rape cage.

I hire a lot of software developers. I really don't care what languages they know. I do care that they are capable of programming, problem solving and working with others. It's also important that they be willing to use whatever languages the team they are plugging into is using already. If they already know the language, that's just gravy. People hiring based on languages listed - particularly on a resume - are lazy hiring managers and probably not who you want to work for anyway.

While it is nice to see an article discussing real issues in mathematics, it is a little sensationalist in places. While formalized proofs amenable to computer proof checkers are definitely a good thing, it isn't really the case that math is going to fall apart or turn out to be wrong any time soon. For starters a surprisingly large amount of mathematics has actually been fully formalized to that level: check out metamath for example. Second, while complex theorems at the edge of current research may potentially have an issue (it was issues with some of his proofs in very abstract homotopy theory and motives that made Voevodsky a convert to computer formalizable proofs), the vast majority of math is used routinely enough by enough mathematicians (and verified by students as exercises) that errors are at this point vanishingly unlikely. Finally, if by some bizarre circumstance something did go wrong, the result would be a patching of axioms assumptions to make most of the mathematics we have true again -- at the end of the day math has to be useful; as Russell said in Introduction Mathematical Philosophy:

We want our numbers not merely to verify mathematical formulæ, but to apply in the right way to common objects. We want to have ten fingers and two eyes and one nose. A system in which âoe1â meant 100, and âoe2â meant 101, and so on, might be all right for pure mathematics, but would not suit daily life. We want âoe0â and âoenumberâ and âoesuccessorâ to have meanings which will give us the right allowance of fingers and eyes and noses. We have already some knowledge (though not sufficiently articulate or analytic) of what we mean by âoe1â and âoe2â and so on, and our use of numbers in arithmetic must conform to this knowledge.

The practical applications of mathematics to science and engineering have been so rich and so effective that any new "corrected" theory of mathematics that didn't recapitulate the same results would simply be ignored or rejected. We would instead modify axioms, or logic itself until we could regenerate much of the mathematics we have.

That's the good case where you just have to move a factory. For many industries it is all about complicated supply chains, which you can't just move wholesale because you likely don't control a large portion of. Unentangling a supply chain enough to make it tractable to move the parts of it you can control to the US could easily take many years in and of itself, if it is really possible at all. What do your contracts look like? What do the other companies tangled up in your supply chain have in the way of contracts?
