Ok so basically you have a Transactions table as well as a separate Accounts table which stores balances, and every time Alices wishes to pay Bob, a (database) transaction appends an entry to the Transaction table and updates balance in Acc

Maybe it’s just me but I’m not getting if those senior engineers are just observing those meetings or whether they are expected to contribute or even take major action points upon themselves. In other words, if there is a set of engineers w

So you're saying each line records the new value of the source and destination balance, rather than just the sum that is being exchanged?

I did read the article. I agree that there is a difference between "wood" and "furniture". Although maybe a more apt comparison is IKEA vs another furniture store. With IKEA you have a relatively basic "style".

Not sure I follow. It's one thing to say that a lot of AWS/Azure/Google users take advantage of many managed services. But saying something is not a cloud provider because they don't provide a specific SaaS is kinda weir

Ok, I'll bite. Why is it not a cloud provider? Most importantly, what is a cloud provider in your definition?

I don't have a lot of payment experience, but AFAIK actual payment systems work in an append-only fashion, which makes concurrency management easier since you're just adding a new row with (timestamp, from, to, value, currency, st

Everything is a trade-off. Signal trades some decreased convenience (for example in terms of backup) for some added security. Whatsapp has more “cosmetic” features (polls,…). If you value privacy over convenience and other features Signal

Traditional, permanent no-fly areas tend to be enforced by the drone firmware (via GPS checks), so sometimes there is also a technological obstacle. This is probably not the case here, but IIRC there are criminal charges attached to violati

Let me dream about the one guy working remote for a satellite company and just jumping into a direct VPN with a satellite, won't you? :) All kidding aside, there are some protocols, like FTP or RTSP, which don't play well with NAT

So if you are born in a water scarce town, just move somewhere else. But what if an entire country or a large area has this kind of issue? Don't you need money, or something you can trade, to travel and build a new home somewhere else?

It's not just pipes. Filtering (from bacteria, pollution, ...) is another issue, and it also affects floods (floods are not periodic, so you have to store water, but storing water for a long term is not always safe). Even desalination

I'm just saying that if they use a traditional IP VPN over the Internet, traffic is of course encrypted, but the two endpoints terminating the VPN must have a public IP. Of course, this is not necessary if they simply use UHF radio sig

The overall idea seems interesting, and that graph is cool, but I have to say I'm a bit confused. First, the main market graph uses currency like symbols, as if this was a forex or crypto market. Maybe it's just me, but I was kind

Not in academia myself, but I suspect the basic issue is simply that academics are judged by the number of papers they publish. They are pushed to publish a lot, which means journals have to review a lot of stuff (and they cannot replicate
