The Builders program @solanaturbine exceeded all my expectations. I got what I was looking for in learning and improving my tech skills. But I didn't expect to learn how to put together a pitch deck and think about the business side. At the end of the day, we gotta make money.

RoboticPayments — DePIN Drone Delivery PoC 🚁 Buyer locks SOL in escrow → Drone arrives → RPi4 automatically signs the Proof of Delivery TX → SOL released on-chain. Zero manual payment step. The @solanaturbine DePIN Cohort Q4 2025 with @00shoe & @alolal0 sparked the idea — I took it further: real Pixhawk flight controller, MAVLink telemetry, GPS-verified on-chain payment. From concept to working hardware PoC. This is the Indoor Test — GPS fix replaced by "Drone arrived" demo button. Outdoor Test with real GPS fix coming next. 🔗 Cohort repo: github.com/solana-turbin3/dr… 🔗 My PoC: github.com/kevkaseeker-sourc… On-chain Proof: 🔗 Proof of Escrow: explorer.solana.com/tx/qK2fK… 🔗 Proof of Delivery: explorer.solana.com/tx/3wpVe… Hardware: Raspberry Pi 4 · Pixhawk · M8N GPS · Waveshare SIM7600X 4G HAT · @Staex_io IoT SIM inside the drone prototype

If you’re serious about Rust, you need a proper learning + tooling stack, not just tutorials. Here’s a clean Rust roadmap with topics + resources 👇 ⸻ 1. Core Language Foundations Topics •Ownership, borrowing, lifetimes •Pattern matching •Enums & algebraic data types •Traits & generics •Error handling (Result, Option) Resources •The Rust Programming Language (aka The Book) •Rustlings •Rust by Example ⸻ 2. Memory & Performance (Rust’s superpower) Topics •Stack vs heap •Move semantics •Zero-cost abstractions •Smart pointers (Box, Rc, Arc) •Interior mutability (RefCell, Mutex) Resources •Rustonomicon •“Learning Rust With Entirely Too Many Linked Lists” •Jon Gjengset’s YouTube (must-watch) ⸻ 3. Concurrency & Async Rust Topics •Threads & channels •Send / Sync •Async/await •Executors & runtimes •Pin, futures, task scheduling Resources •Tokio docs •Async Book (rust-lang) •Jon Gjengset async deep dives ⸻ 4. Tooling You Must Use Topics •Cargo (workspaces, features) •Clippy & rustfmt •rust-analyzer •Profiling & benchmarking Resources •Cargo Book •criterion for benchmarks •perf, flamegraph ⸻ 5. Systems Programming Topics •File I/O •Networking •Memory-mapped files •OS interaction •Unsafe Rust (when and why) Resources •std::fs, std::net docs •Rust for Rustaceans (book) •OSDev Wiki (concepts) ⸻ 6. Backend & Distributed Systems with Rust Topics •HTTP servers •gRPC •Serialization (serde) •Databases & drivers •Backpressure & async IO Resources •Axum / Actix •Tonic (gRPC) •Serde docs •Postgres + SQLx ⸻ 7. Testing & Reliability Topics •Unit vs integration tests •Property-based testing •Fuzzing •Deterministic tests Resources •proptest •cargo-fuzz •Rust test book ⸻ 8. Real-World Rust Codebases (Study These) Projects •Tokio •Ripgrep •Servo •Wasmtime •Rust compiler itself ⸻ 9. Advanced Rust (Where Most Quit) Topics •Lifetimes in APIs •Trait objects vs generics •GATs •HRTBs •Zero-sized types & typestate Resources •Rust RFCs •“Rust API Guidelines” •Compiler error messages (seriously) ⸻ 10. Build in Public (This Is Non-Optional) Actions •Write small crates •Rebuild simple tools in Rust •Blog about borrow-checker pain •Share benchmarks & learnings ⸻ The Rule Rust rewards depth, not speed. If you rush, you’ll bounce off the borrow checker. If you persist, you’ll think differently about software forever. Pick one domain (backend, systems, blockchain, infra) and go deep with Rust there. That’s how learning Rust actually compounds.

Since it seems like literally nobody knew that you could just send transactions directly to the TPU of the leader, I made this leader list to show you the upcoming leaders IP and TPU port. You're welcome. leaderlist.vercel.app/

You literally can actually send transactions direct to the TPU, had no idea, infact I didn't quite believe the timing so I had GPT 5.2 and Opus 4.5 confirm it. @jacobvcreech RPC's are for reading, TPU is for writing. Is this a new thing, is this something that Solana has always had? Why wouldn't everyone just do this? nitter.siddz.com/jacobvcreech/status/20… github.com/stevesarmiento/pi…

Capstone Demo - 8 | Q4 2025 Solana State Channel, which aims to increase performance by handling transactions off-chain and settling them all at once on-chain. From @00shoe #Turbin3Tribe

The largest Solana Treasury company, Forward Industries, recently added @aseidman with @Hivemapper, @amirhaleem with @helium & @mikeahorton with @geodnet as advisors! It's very evident that @solana is making DePIN a priority! nasdaq.com/press-release/for… solana.com/solutions/depin

As always, fearlessly pushing the @solana ecosystem forward - We have been working with hardware for a long time at @solanaturbine 💪We were ready to ship, and we showed it! 👇Check out the highlights from our demo day. Thanks @SolanaFndn, @helium , @onocoyRTK , @Hivemapper , @unruggable_io , @wedtm for your support!

This is the latest white paper on the DePIN drone delivery system --> drive.google.com/drive/folde… Two months have passed since I published the first version of the white paper. In the meantime, I have met many new people. Many thanks to @SuperteamDE and @solanaturbine -- especially to @pattiruss_ and @zCase_ -- for introducing me to the web3 community of the @w3_hub and Berlin. And a big thank you to @japarjam for letting me be part of the DePIN-Cohort. The next goal is the @colosseum hackathon which I’ll be joining together with @00shoe

A multirobot system, developed by a Caltech research group and TII in Abu Dhabi, has a Unitree G1 humanoid launch a transforming drone from its back.

#Toolapalooza! Who else is going? 😀

This is the power of YOLO, trained on a laptop for ~1 hour, with a Kaggle dataset. Oh, and just ~100 lines of Python. I can make a startup on this and it took me literally a couple of hours.

Open source fucked me over. A @SuperteamIN member copied my @colosseum submission line by line, won a @SuperteamEarn grant for it, and I got nothing, not even credits. Read this thread, see how this faker got it all and what he did when I confronted him. cc: @solana 1/8

There's no music without artists. But in today's industry, they're locked out of the economy they create. That ends now, with Artist Coins on @solana. Introducing Audius v1.0: the Open Audio Protocol, and the realization of our 2020 whitepaper 🧵

The friend who needs to respect others’ privacy more

Incredible that we can launch crypto companies in the US without feeling extreme uncertainty about whether it's criminal. This was a huge part of my reluctance initially to start a crypto company. This is huge for innovation 🇺🇸🎆 Congrats to @doublezero!

I just minted my Turbin3 Builders Cohort NFT! Can't wait to dive into the advanced programs! 🚀 Check it out: turbin3.org/gradnft/q3-2025/

For early morning class, it takes a bit for my brain to get moving. But within a few minutes of starting I heard the word robots, and I was good to go 😃

The L1 premium has finally been isolated under laboratory conditions—behold!

Did you know that there are over 20 cracked hardware engineers all building DePIN for Solana together? The energy with the @solanaturbine DePIN is electric! Expect big things from this group!
