Of course the issue is that for a reasonable user experience you will need bridges between rollups, which suffer from alle the same problems.

Can you elaborate on how it's centralized? I keep hearing this but they have 1400 active validators all over the world, which is more than most smart contract chains except Eth

The problem of course is that IP addresses can totally be used by Google to build up a profile of your browsing behaviour across the whole web. Even if typical end User ip4 addresses change quite a lot due to ISP NATs I imagine it's st

When I moved to Australia I needed to get some documents (uni degree, work experience etc) verified by the Australian Computer Society. They required me to get a notarized copy of the original and SCAN the notarized copy, to be uploaded ele

If you are slightly risk-tolerant you can use services like nexo or blockfi to earn interest on fiat. You don't take crypto price risk and they generally only lend out money on an over-collateralized basis, so the default risk is small

(I am hugely sceptical on most things crypto) generally speaking the view of a rich, stable country might make you blind to some real use cases because you just don't have them. But for people in less privileged countries having a perm

Because of course all companies exist in the same time zone as all their clients... Have you ever worked at a SaaS company? Having customers from around the world is literally a thing from day 1, especially if you are not US or (to a lesser

I mean it really depends on what the oncall looks like. If your system breaks every 5 minutes or you have other teams escalating non-urgent tasks constantly then 1 week on call seems crazy. But there are many companies (mine included) where

Australia has had instant, free interbank transfers for years now (PayID) but for some reason I have yet to see a business accept it at PoS and only very rarely for online purchases. The only business that seem to accept it are crypto and s

I think it's really difficult to compare all of these statistics. Take Germany: It is very normal to rent your whole life, especially in big cities. Renter laws are very strong. House ownership is higher in rich, rural parts of the cou

That is what I was thinking. But does that mean you just pepper your command processing logic with guards that you are still actually the leader? I think one mistake I made is trying to run the different parts of the protocol in parallel, i

I took the MIT Distributed Systems course and also got stuck several times on how exactly something should be done. The Raft paper is good but in practice I found it quite difficult to reason about when certain things should be allowed to h

I mean 60W is very low, probably 90-100W is the sweetspot? I have a Legion 5 Pro which supplies 130W and that's pretty much the highest you will get. I am pretty sure perf/W for the M1 Max chips is excellent, better than the 3060.

by valzam 5y ago
Just FYI because I've seent that a few times already: A 60W/70W 3060 is -very slow-. There are many laptops that supply much more power and conversely also get better results.

Not just recursion but also error handling. Gets all the if x = nil checks out of the way and the actual function only has Business Logic. Same for functions that need to operate differently based on input, no pollution of the body with if

Becoming fluent in using all the different ways to iterate over traditional collections (map,flatMap, fold, reduce etc.) already takes some time. Extending that to things that programmers don't normaly think of when they think "lo

Not OP but for analytics use cases it is common to create new tables for each minute, hour, day or whatever granularity you collect data in. This makes it easier to aggregate later, you don't end up with extremely big tables, you can d

My favourite unpopular opinion: Microservices are a great way to enable 100 engineers to work on a product when otherwise you would have needed at least 10 engineers to achieve the same.

FYI Google Pay actually creates a new "credit card", i.e. a single-use token for every payment, something along those lines would probably be great if more widely adopted. https://support.google.com/pay/mercha

This partly exists. But could of course be much simpler to use: 1) some banks/fintech offer virtual cards. For example, whenever I need to pay with credit card at a site that seems to be using some homegrown system I create a new virtu

I am not sure what weight you assign to each of your requirements but DynamoDB has official Docker containers that you can use for local development. I don't find it different than developing against postgres etc. If you have tried it
