The difference between multi-sig and no private key is that the former is an implementation of the blockchain protocol (e.g. different in Stellar and Ethereum) while the latter is a generic algorithm/service. Different layer.

Disclaimer: I work for a competitor.

Multi-party computation (MPC) enables you to participate in public key cryptography with shares ("parts") of a private key divided between multiple participants from the get-go, i.e. without ever having the private key in memory at any point in time.

So for example, if you divide the shares between mobile devices and servers then all of them would need to communicate with one another to sign a message without any of them knowing the private key. There are variants (e.g. 2 out of N, etc.), but that's the gist of it.

Connecting it to cryptocurrency wallets, you can then use this scheme to create accounts where the control is shared between multiple devices and "mathematically" it doesn't matter then if one of the devices is compromised - it could never do anything on its own.

Really liked Hypernormalization by Adam Curtis on the phenomena: https://youtu.be/fh2cDKyFdyU

How is SEV compared to SGX?

If you could find this analysis later I'd appreciate is as well, because I have OP's intuition that retail couldn't cause this

> Sorry, what are you trying to say here? The Dutch had the pleasure of hosting what exactly?

Hosted a party! In seriousness though, s/he refers to the German occupation of the Netherlands in WW2.

When you say exhale, do you mean from the mouth or nose? Does it matter?

I really enjoy my Pilot Metropolitan, even more than pens costing x5 the price.

Anyone knows of anything similar for portfolio websites? Aimed at front end developers

If anyone thinks of implementing this, don't forget to guard against reflection attacks[1]

EDIT: revisiting my comment (and the wikipedia article linked), a reflection or amplification attack in this context is sending traffic and generating (perhaps much more) traffic from a different source than yours as part of an attack. For example, you could spoof the IP address of the HTTP packets and cause the server to port scan another machine -> little traffic (HTTP request) causing a lot of traffic (port scanning). As part of a DDOS attack, a botnet for example could use this to amplify their attack and masquerade the source.

I'm intrigued by actual use-cases for it except exploring, i.e. where it would give better result for a query than the common search engines.

Anyone reading this, please post if you find any

Let's assume there is no technical way the contact API can be misused. You've still conditioned massive swaths of the population to be electronically tracked, boiling frog and all.

These are extreme times, so Amazon the mega-corp that it is should probably not nickel and dime customers of money that can be used towards more immediate needs.

Probably international. I see this kind of gap regularly when comparing buying from Amazon v.s. directly from the supplier. Internet stores are surprisingly bad (for whatever reason) at pricing international shipping competitively.

I did and I loved every moment of it :) Also in meatspace, enjoyed Bletchley Park in the UK.

Re: books, I liked Robert X. Cringley's Accidental Empires, but it covers only until 91 (or 93 if IIRC for the 2nd edition) of the PC industry and not really technical.

I LOVE this kind of technical computer history! Anyone knows of other recommended resources?

Source? Genuinely interested

They cite “family values” and have an illustration of a heteronormative family on the “morals” page. Does that mean they filter gay-related results? Gay marriage related results? Would you prefer them to filter it?

I have no idea if they do, but it’s foolish to even cause such questions and disambiguation with your brief (which you inevitably do when you do “morals”)

Not having a specific behavior at infinity != doesn't having an effect

> Try the semantic map of https://swisscows.ch/

Was excited to try it more after an initial impression, but this is a no-go for me:

> 1. We promote moral values.

Which of course is code word for "We promote our values". Can't believe we're in 2020 and this is part of a pitch.

Why the relative high cost of threads on ARM? If anything, I'd imagine it is more geared towards "massive parallel" scenarios (i.e. dozens of cores).

> We didn't write any documentation or have any internal wiki or anything like that, and everything seemed fine.

Just evidence that documentation != institutional knowledge. It's not actionable knowledge if no one reads it.

> Someone's just bought a $1000 call option on a stock that's currently $400? Automated trading systems will probably raise alerts on that stock since someone must know something for that to happen.

The trading system and its operators deserve whatever fate results from such a decision.

I use it when needing vast geographical spread - e.g. nodes that are closest to exchanges or some such.

Because so many others use it, if you care about latency to the counter-party server it's often a nice way to ensure low latency (by using the same availability zone).

I feel like I’m taking imagination-b-gone pills. The only potential uses off the top of my head that I’ve witnessed are credentials management and financial instruments arbitrage, and in both cases it was solved well by other measures.

I’m sure there are projects where it’s useful, but not “every company” useful like SQL or even a server supervisor framework. I would be happy to be proven wrong.

Would personally be happy to see more skills of which the importance has rapidly risen in 2020 or expected to rise.

Exercise has always been important. So has connecting with people or marketing.

Do they though? Haven’t seen many companies with graph problems at such scale that require a new solution integrated, leaving aside the social network trope

Someone who is more versed in the usual statistics, how serious is it? Without domain knowledge, I have no idea if the few dozen deaths in this period at these locations is significant or not.

My thoughts exactly. It's a shame that such interesting developments are shadowed by the brand-name and infamy.
