You're on a tech focus site here. Age discrimination almost certainly goes one way in these cases. That's if you're above 40, and looking to join an early stage start-up, you'll find you're often not a culture fit.

Great job with this. What's your roadmap for releasing some of the tooling for editor integration? Really, the question is should I build something or wait a few weeks?

Go removes non-value added decisions as teams scale: - formatting built in. There’s one way. No preferences needed - language constructs are dead simple. There’s one way to use them, and they’re verbose. No cleverness encouraged - patterns

The thundering herd problem in distributed systems is an often unexpected failure mode. This is great, and easy to plan for. You'd save buckets of money because most capacity is used for spikes, and you now have a good idea of when spi

I'm ignorant of this space. Can you share how Robinhood and others make money through order flow? The semantics of it (an order has to receive the best price at the time of execution for example) doesn't capture the N ways a fund

I take it back. S3 outlines this exact use case: https://docs.aws.amazon.com/AmazonS3/latest/userguide/IndexD... Because of this, I agree, they should verify domain ownership to help protect their users.
804.
by ctvo 5y ago
The point is that S3 isn't a CDN. If you use it as a CDN, it's on you to ensure it'll work for your use case. CloudFront, however, is a CDN, and as expected, has domain verification.

by ctvo 5y ago
S3 is not a CDN. S3 is a distributed file system. Use a CDN for CDN use cases (CloudFront) and you wouldn't have these issues. There's a chance a normal AWS user may not understand the above distinction, a sophisticated actor like

Or use CloudFront with an S3 bucket as backing for this use case, like you'd expect? CloudFront has domain name verification.

A lot of windows are small and temporary. In this case the attacker could have served anything out of the S3 bucket and conducted full blown phishing (google.ar, coinbase.ca), and generated valid certificates. It's a big deal the order

This is the reverse situation. What's going on here: - Bob makes bob.com and sets the CNAME to be bobstaticsite.s3.aws - Bob forgot to make a bucket called bobstaticsite.s3, and Alice, scanning the DNS records, creates it instead. Now
