In my career, compilers have always generated better code that I ever could have. I find this to be increasingly so with contemporary AIs.
But you know what neither can do better than me?
Knowing what software to write, what shape it should take, and what I want it to do.
The entire history of software engineering has been one of rising levels of abstraction.
This is how it was, how it is now, and how it shall be in the fullness of time.

Threshold encryption, so hot right now.
New paper alert! 🚨
Weighted Batched Threshold Encryption with Efficient DKG
w/ Alexander Frolov, @AditiPartap97, and @ErtemNusretTas
In multi proposer consensus, transactions should be hidden until “valency”, the point of no return at which the consensus outcome has been decided. The cleanest way to achieve this property is with threshold encryption. But existing schemes forced difficult tradeoffs between batched, weighted, and efficient schemes. I asked the @a16zcrypto research summer interns if they could come up with a new scheme that was weighted, batched, performant, and didn’t require a trusted setup. Turns out they did!!!
With some optimizations, I was able to get decryption for up to 16 simultaneous proposals to run in ~40ms on 12 cores with thousands of virtual shares and decryption shares that are small enough to fit in a single UDP packet along with the rest of the vote data. This leaves enough performance headroom room on my dev box to run a full Solana validator at the tip with the remaining cores!!!
These results, along with other recent work in threshold encryption are finally pushing threshold encryption into the realm of practicality for use in the Solana protocol. We still have some more optimizations to try so we might be able to push it even lower!

Please stop bulk calling getTransaction.
We don’t mind, and will happily let you do it, but you’re going to spend 100% more than if you just use Jetstreamer.
Plus it’s faster.
We frequently get requests to bulk backfill Solana ledger history, and we recommend Jetstreamer + Old Faithful because it is fast & free. Trying to do this through an RPC is just dumb. Jetstreamer is from @anza_xyz and Old Faithful is from @triton_one. Don’t be dumb

Many years from now, when all of you gen-z kids are trying to buy a house and spend 6 months proving your finances and that your not a terrorist, please remember that it was your lack of outrage at things like this that caused the rest of the world to champion regulation.

I see the OpenClaw crowd has found a new psychosis and are calling it Jev.
Rumor has it they'll all be buying Cisco Nexus 9336C-FX2's so that their LLM's can classify the fastest.
Little do they know it can be distilled into 25 lines of Python. nobodywho.ai/posts/jev-in-25…

achieving 3,500,000 transactions/sec fetching + parsing Solana blocks on a single machine! using jetstreamer
less than 3 minutes to parse all transactions in an epoch
75Gbps machine so there's more headroom, but start hitting upstream 429s if we fetch much more

SOLANA ASSEMBLE!!
Free idea to fix Flock: encrypt all video and give residents control over unlocking it. Police can request bounded access per incident, but a majority of residents has to ok.
Threshold cryptography / m-of-n authorization, maybe MPC so no single party ever holds the master key.
