Build with what pieces you can find, rather than plan the perfect structure ahead. Improvising keeps the creativity going! Wheres fun if sorting legos sucks all the Joy from it

Those FAANG devs have milions of (social) lives on the line, though. Every day.

You can apply dynamic env to other jobs by exporting an env file as a dotenv artifact. So first job creates a dotenv file and export it as artifact. Second depends on the first so it can consume the artifact. https://docs.gitlab.com/ci/yaml/artifacts_reports/#artifacts...

Why do you need the vector if you have already compared the query with the result candidate?

Its not difficult to imagine a person saying 'i have nothing i want to share here' be stigmatised in future. As a person who doesnt want to work together and be part of the company culture.

1) IMHO, people use quantifiers like majority, mostly, rarely, etc not because its the absolute truth, but because its their subjective PoV

2) Dont trust everything you read on the internet. A lot of it is skewed by personal biases.

High level devs still do low expertise things every now and then. Or rather, designs need to be implemented, eventually.

Re whys: this can be even simpler. I sometimes catch myself rapidly click the mouse button a second time with my finger, right after the initial click. This is not intended and may be related to low resistance on the button itself.

Yes, although timestamps may have collisions depending on resolution and traffic, no? Bigserials (at least in PG), are strictly monotonic (with holes).

PG bigserial is already strictly monotonic

When running a batched migration it is important to batch using a strictly monotonic field so that new rows wont get inserted in already processed range
