PhD level science questions? (+1)

niftydude an hour ago

A PhD level science question is a question that can only be answered by scientific research and experimentation.

And no, by “research”, I do not mean googling.

Literally the whole point of a scientific PhD is to perform experiments and study to answer a specific research question that no one has looked into yet.

I like to think of it like this. It takes approximately five months of power, relatively speaking to power, the human brain vs. multiple megawatts hell even multiple gigawatts of power to power even some of the most modest and yet surprisingly complex AI models. ⌘ Read more

If you derive your income from producing “elevator music” you might indeed be in danger of losing that income to AI. Also, bumper musi … ⌘ Read more

Problem 2: Your SSD-backed database has a usage-pattern that rewards you with a 80% page-cache hit-rate (i.e. 80% of disk reads are served directly out of memory instead of going to the SSD). The median is 50 distinct disk pages for a query to gather its query results (e.g. InnoDB pages in MySQL). What is the expected average query time from your database?

Also interesting:

edit_hash: When a message is edited, a new message is created– this field holds the hash of the modified message. The client follows the chain of edit hashes to end up at the final, edited message to display. This lets us keep an “undo” history (not yet implemented) and is a marker so the client can display a marker that the message has been edited. ⌘ Read more

    My solution to:

How much will the storage of logs cost for a standard, monolithic 100,000 RPS web application?

  • 512 bytes logged per request

  • 100,000 RPS

  • ~50MB/s

    • ~4TB/day

  • $0.02/GB Blob Storage

    • $0 ingress

  • 90 days retention

    • ~400TB

    • $8k Blob Storage

  • Costs:

    • ~$88/day

    • ~$2.6k/month

    • ~$32k/year ⌘ Read more
