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.

"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.

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.

This seems to the most likely, and it's not unheard of, they have 'local regions' like osaka in Japan.

Alternatively they could just stick a bunch of Outpost racks in the NYSE/NASDAQ data center and create an 'eXn.8xlarge' instance type and charge 100$ an hour.

The biggest current limitation with cloud providers when it comes to exchange tech is the lack of real multicast support. It is rare outside of exchanges, but extremely low latency L1 multicast market data has become the backbone of exchanges, both for fairness and for scalability.

Knowing you can saturate your entire network with 10G traffic and every participant will get the same market data packets at the same time[0], and there will be zero queuing or bottlenecks is very hard to do otherwise. There is a pretty good podcast episode about it out of Jane Street[1].

I know AWS have 'multicast support' but last time I tested it, it was clearly just uni-cast traffic with a software switch doing fan-out/copying, I assume using the same tech as their transit gateway, I think it was called hyperplane or something.

[0]: for some definition of the same time, at least low enough that you can't measure it without equidistant optical splitters or White Rabbit synced devices.

Just for fun, because it's hard to appreciate how strong a 256bit ECDSA key is.

Base Numbers:

- 2*128 guesses on average

- public state of the art for ECDSA on an FPGA is 1315tps [0]

- retail price of said fpga $10,000 [1]

- total net income for xilinx from advanced FPGAs FY2022 (936M * 0.74 + 879M * 0.72) = 1325M [2]

Ballpark numbers, we'll assume that attacker can buy 10x every FPGA xilinx made in 2022 for a 50% discount and can run them non stop for zero cost.

We'll also assume they have a bunch of secret math geniuses and have a faster ECDSA implementation that can do 1,000,000,000 tps ( or 1,000,000x SOTA)

- (1325,000,000 / 5,000) * 10 = 2,650,000 FPGAs

- 2,650,000 * 100,000,000,000 = 2,650,000,000,000,000tps

- 2*128 / 2,650,000,000,000,000 = 1.28e+23s

- 1.28e+24 / 60 / 60 / 24 / 365 = 4,080,000,000,000,000 years

- ~4 quadrillion years

- or 4x the time until every planet has been ejected from every star system and the sun has cooled to 5K [3]

But why stop there, lets assume that the attacker can use the entire planets GDP to buy chips and has a 1,000,000,000,000,000x faster ECDSA implementation.

- World GDP (2022): 101.3 trillion

- (101,300,000,000,000 / 5000) = 20,260,000,000

- 100,000,000,000,000,000 * 20,260,000,000 = 2.66419e+28tps

- 2*128 / 2.66419e+28 = 12,772,451,173s

- 12,772,451,173 / 60 / 60 / 24 / 365 = 405 years

So even then, we wouldn't see a single BTC key broken within our lifetime.

(Unless you believe that 3 letter agencies have successfully built a quantum computer that practically implement shore's algorithm, in which case you should probably be more worried about the fact that they can break public key encryption globally)

Have you ever walked into a room and found a vampire?

No, not the sexy kind, but a foul creature with bony limbs and ashen skin? The kind that snarls as you enter, like a beast about to pounce? The kind that roots you to the spot with its sunken, hypnotic eyes, rendering you unable to flee as you watch the hideous thing uncoil from the shadows? Has your heart started racing though your legs refuse to? Have you felt time slow as the creature crosses the room in the darkness of a blink?

Have you shuddered with fear when it places one clawed hand atop your head and another under your chin so it can tilt you, exposing your neck? Have you squirmed as its rough, dry tongue slides down your cheek, over your jaw, to your throat, in a slithering search that's seeking your artery? Have you felt its hot breath release in a hiss against your skin when it probes your pulse—the flow that leads to your brain? Has its tongue rested there, throbbing slightly as if savoring the moment? Have you then experienced a sinking, sucking blackness as you discover that not all vampires feed on blood—some feed on memories?

Well, have you?

Maybe not. But let me rephrase the question:

Have you ever walked into a room and suddenly forgotten why you came in?
