I've definitely noticed this anecdotally.

Especially with Gemini Pro when providing long form textual references, providing many documents in a single context windows gives worse answers than having it summarize documents first, ask a question about the summary only, then provide the full text of the sub-documents on request (rag style or just simple agent loop).

Similarly I've personally noticed that Claude Code with Opus or Sonnet gets worse the more compactions happen, it's unclear to me whether it's just the summary gets worse, or if its the context window having a higher percentage of less relevant data, but even clearing the context and asking it to re-read the relevant files (even if they were mentioned and summarized in the compaction) gives better results.

Most exchanges do not reveal counter-party information smaller than the broker level. So you wouldn't know just from looking at market activity the same person causing the large futures move was also taking large options positions.

I did this route (sans the new Laos line, which was a bus at the time) in 2014. The world really was a different place.

Shout out to 'The man in seat 61', couldn't have done it without it.

"Jumbogram", an IPv6 packet with the Jumbo Payload option set, allowing for an frame size of up to 2³²-1 bytes.

At 10Gbps it would take 3.4 seconds just to serialize the frame.

I realise you can make games in any language/engine. But could you explain the language/system/engine you used?

How did you go about validating the game is fun? Did you end up having an intuitive sense for it, or did you need external feedback to refine the mechanics?

My steam deck might as well be a billionaire/balatro machine.

It's always interesting to note the waves of sponsors flow through youtube/podcasts. Raid, Nordvpn, recently Incogni. I wonder if the ad spend actually pays off for them, or if it's just VC dollars being shoveled into the furnaces.

In theory yes, over a geological timescale. In practice, it would be like worrying about the sun expanding and engulfing the earth, when it reaches its red giant phase, when you are installing solar panels.

- replace human artists

- build more efficient killing machines

- destroy any remaining concept of privacy

I was in Shanghai this year, and in the city center, it is actually unsettling how quiet it is. Every motorbike is electric and probably 70% of the cars (at least in the CBD). It's not silent by any means, but the background hum of motors is mostly absent, it took me a while to even realise that is what felt off. Like watching a movie with the sound effects removed.
