Hmm, even though LastPass doesn’t have access to your pass, couldn’t a malicious software update cause attacker to view your passwords when it runs since the software ultimately has access? This doesn’t seem to be the case in this incident

Air gapped wallets can utilize QR codes to sign transactions. Look into PSBTs (partially signed bitcoin transactions). Gist is you can create a transaction from any device that doesn’t have your private key … send that transaction via a QR

Woah thanks for sharing your situation. Talking about it to others sounds like a step in the right direction. One thing to consider is what you are teaching your kids by staying. Kids have a habit of picking up on these things at an early a

I absolutely love DynamoDB. Would definitely recommend the DynamoDB Book by Alex Debrie and Advanced DynamoDB Patterns by Rick H on YouTube. Once you understand how to properly use dynamo and what it’s good at it you get so much power; at

We currently do this. Team is compromised of folks across multiple time zones so it comes in handy. However, I do feel like synchronous stand-ups are more productive

Are you doing this solo? I’ve found it’s good to have partner(s). Ideally with diverse backgrounds; e.g. - marketing - engineering - sales - finance This way the burden doesn’t fall on you for everything and you can lean on

I wish we had more systems thinking around these problems. From my perspective it seems some are quick to want to change to another system on any signs of problems in the initial system; where the new system fails to have any good feedback

All depends on what’s important to you in that startup context. If you need a good mix of high productivity and low costs on the server side I think go is a good fit. If you don’t care so much about costs and scale on the server side then s

Hmm, can you provide some examples of how a context based iterator is slow? If you need raw performance and you are just doing some minimal operations on a slice then yeah you’d want to use a simple for loop instead. I typically use this pa

Regarding your point on iterators, I typically use a channel with context; this lets you exit that range loop early and will automatically stop the related go routine. (assuming it’s context aware) e.g. func myFunc(cx context.Context) {

A lot of the energy consumption argument against bitcoin stems from this study [1]. Some have pointed out flaws in the study that over inflate the consumption numbers. This has sparked various indexes that have tried to measure the consumpt
