A good read on Async Rust jacko.io/async_intro.ht…

@amritwt Please tell me these guys are actually trolling 😭. WTF

bro what

@shankstwin Write a blog on these topics. Would love to read.

Since 1 week I am deep diving Postgres Here's what I covered : - MVCC — how Postgres avoids read locks - WAL — Write-Ahead Log, crash recovery, checkpoint - VACUUM and autovacuum — dead tuple cleanup - Connection pooling with PgBouncer — pool modes - Row-level security — tenant isolation at DB layer - Logical & streaming replication - Partitioning — range, list, hash, partition pruning - Full-text search — tsvector, tsquery, GIN indexes - JSONB with GIN index — flexible dynamic data - Window functions — ROW_NUMBER, LAG, LEAD, PARTITION BY - CTEs - common table expressions, recursive CTEs for trees - B-Tree — node structure, split/merge, height, range scans - Hash index — O(1) equality, not suitable for range - GiST — generalized search tree, geometric/range types - BRIN — block range, massive naturally-ordered tables - Partial indexes — WHERE clause, smaller, faster updates - Expression indexes — index on function result - Covering indexes — INCLUDE clause, index-only scans - EXPLAIN ANALYZE — reading query plans, actual vs estimated - N+1 query problem — identifying and fixing with JOIN Still learning covering more things I am really enjoying how things work and revising old concepts Will keep updating this list

Earlier today, a malicious actor gained unauthorized access to Drift Protocol through a novel attack involving durable nonces, resulting in a rapid takeover of Drift’s Security Council administrative powers. This was a highly sophisticated operation that appears to have involved multi-week preparation and staged execution, including the use of durable nonce accounts to pre-sign transactions that delayed execution.

Rust Atomics and Locks is a great book to learn low-level concurrency in @rustlang . It covers a ton of really cool topics and has some projects that you can build.

@FrancescoCiull4 Couldn't agree more. Every day, I see some good news related to rust.

Every single Rust joke is making Rust more adopted and more famous. Keep 'em coming!

@SolanaSensei @UmbraPrivacy @JupiterExchange @encrypt_xyz Private transactions, privacy onchain 👀. Gotta try the SDKs to build something cool

24 HOURS ON SOLANA - You can now build privately with @UmbraPrivacy SDK is now live. Any Solana team can now integrate privacy into their application - @JupiterExchange cashback referral multipliers now live! For 7 days only, referral rewards are 2x. - @encrypt_xyz is coming to Solana. Fully homomorphic encryption for the Solana Virtual Machine. - @ikadotxyz is coming to Solana - @symbiosis_fi now has full solana support - @StraitsX’s $XSGD and $XUSD are now live on Solana - @FluxRPC is now live and free to start. FluxRPC → Fixed RPS, no over billing, no surprises. - @magicblock Private Payments API is now live on @Solana. Add confidential SPL transfers into your app in minutes with one API call.

@TukiFromKL Aren't researchers already working on quantum-resistant encryption algorithms?

🚨 Do you understand what Google just published.. they said a quantum computer could crack Bitcoin's private keys in 9 minutes.. everyone's panicking about crypto.. but nobody's asking the real question.. if quantum cracks Bitcoin.. it also cracks your bank account.. your credit cards.. SWIFT transfers.. stock exchanges.. military communications.. nuclear launch codes.. every single HTTPS website you've ever logged into.. the same encryption protecting your savings account at Chase is the same encryption protecting Bitcoin.. if one falls.. they all fall.. and here's what nobody's telling you.. this needs 317,000 qubits to work.. the best quantum computer on earth right now has about 1,000.. they announced a countdown.. and the clock just started.

@feggnews @_jason_today Right now, most of the use cases you see are flashy stuff. I'm sure we'll see better use of this tech in the coming days.

@kroy_3 @_jason_today Every demo I've seen of this technology is just an unreadable eyesore then a bunch of clowns show up to yell that you "just don't get it"

All the demos I'm seeing are text moving all over the screen. But what about an editor with pixel perfect syntax highlighting? You can do it with only little effort on the web now.

@inspiration_gx @solanaturbine yes ser 🫡

@kroy_3 @solanaturbine Upward and onward 🫡

Successfully completed Accelerated Builders from @solanaturbine Team Bond delivered a fantastic capstone, implemented a bonding curve launchpad.

It's kinda wild how fast things are moving nowadays.

Worked on a simple log aggregator system in Rust - Simple ingestion endpoints using axum - Redis for storage (For a simple prototype, it felt easier to build on) - WS for realtime log streaming

It was an insightful Sync up call with @japarjam and Pre-Builder fam.
