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?

  • Page size 1MB
  • Median 50 pages per query
  • 80% pages cached
  • 200us SSD reads

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.

Whilst ChatGPT can probably can answer “PhD-level science questions” with the same generation of plausible bullshit it answers all questions, I very much doubt ChatGPT can answer PhD-level science questions with any sort of accuracy.

It can’t do that without performing experiments (that in some cases might be complex enough to last years).

Just more of the marketing BS silicon valley seems to be full of these days. Remember when California was actually making products that benefited society as well as making money?

No he jugado tanto el Pokemon TCG, más que en Game Boy y ahora en teléfono.
https://play.google.com/store/apps/details?id=jp.pokemon.pokemontcgp

Es un juego que, al menos en la primera parte, está muy bien hecho, aunque al poco tiempo se acaba el factor ‘wow’.

Como vemos en ‘Leyendas y Videojuegos’, el juego móvil es más una demostración para una experiencia de como sería que colecciones las cartas
https://www.youtube.com/watch?v=zpAZCy8_-UI

Siento que mucha gente va a interesarse en coleccionarlas gracias a este ‘demo’.

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.

There is something about human intelligence that we don’t quite yet understand, and it isn’t in the complexity or increasing the number of parameters to the order of billions 🤣

@movq@www.uninformativ.de This random comment from another Slashdot article pretry much sums up my view on so-called “AI”:

Elevator music
Tony Isaac 20 minutes ago
If you derive your income from producing “elevator music” you might indeed be in danger of losing that income to AI. Also, bumper music–music used to fill otherwise silent gaps between segments of a podcast or radio show–might be a candidate for AI takeover.
But if you produce real music–music with depth and emotion–your job isn’t going anywhere.
How can I be so sure? I’ve seen the kind of code AI writes. I’ve seen the kind of prose AI writes. Both are amazing, for something computer-generated. But neither would be mistaken for the work of someone skilled or proficient in the art. Music won’t be any different.

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.

  • 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
