It's that time of the year again, Rust Nation UK. We are excited to have Rustaceans who have flown in to meet the London community, forge new friendships, and engage in insightful discussions. Tickets are still available for the conference. Community Promo code: RustLDN2026 [https://www.rustnationuk.com/tickets](https://www.rustnationuk.com/tickets) **Community Showcase** \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\- **Iason Paraskevopoulos** **Title: Building an OSS Remote Pair Programming App in Rust** **Abstract:** Hopp is a multi-user remote control and screen sharing app designed for fast, natural collaboration. This talk walks through how the system works end-to-end, from cross-platform screen capture and input handling to low-latency video streaming. It covers why we chose Tauri for cross-platform development early on, the headaches caused by WebKit’s inconsistencies and WebRTC issues, and why we are moving towards a Rust-native UI. **David Wood (Rust Compiler Team Co-Lead)** **Title: Extending Rust’s notions of sizedness** **Abstract:** This talk is based on work I am completing upstream as the co-lead of the compiler team and the lead of Arm’s Rust team. It is based on this RFC - https://github.com/rust-lang/rfcs/pull/3729, which is partially implemented. We hope to stabilise the implemented parts before this talk is presented. More Talks to come......

With LLMs becoming increasingly normalized in the industry, an overreliance on them can allow bugs to slip through the cracks.* *In this talk, I'll demonstrate a practical debugging workflow: Debug first. Prompt second. I'll show how browser DevTools reveal what's actually happening faster than any AI can guess.* *You'll learn:* * *Essential DevTools features that improve your bug-fixing prowess* * *When to reach for your browser and when AI can actually help* * *The almost forgotten art of breakpoints and strategic console messages* *AI in your codebase represents growth, but understanding your runtime state represents mastery. This talk is about balancing both and knowing which tool to reach for first.* ➡️ **Why Your Marketing Scripts and Cookie Banners Are Ruining Your Lighthouse Scores - [Christopher Burns](https://www.linkedin.com/in/burnedchris/)** *Most marketing scripts and cookie banners run on the critical path. They block the main thread, delay first paint, and inject third-party code before the page is interactive.* *Consent managers often make this worse by synchronously loading vendors, mutating the DOM repeatedly, and re-hydrating UI after page load. The result is slower LCP, higher TBT, and unstable CLS.* *The fix is not fewer scripts, it is better orchestration. Treat consent as infrastructure, load vendors after intent, and keep compliance off the critical path.* — **👍 Code of Conduct** By registering for this event you agree to comply with our [CoC](https://gitnation.com/coc) **📩 Contact** events@gitnation.org https://twitter.com/ReactAdvanced http://youtube.com/ReactConferences https://bsky.app/profile/reactadvanced.gitnation.org

Meeting @ Improving's office in Downtown Columbus, near Cosi. Parking is paid, food & drink are free! This time we're hanging out after the long winter break.

Can two girls—one enchanted, one the enchantress—save their kingdom and each other? Two hundred years ago, a slighted deity stole the magic from Auréal and vanished without a trace. But seventeen-year-old Odile has a plan. All her life, her father, a vengeful sorcerer, has raised her for one singular task: infiltrate the royal palace and steal the king’s crown, an artefact with enough power to restore magic. But to enter the palace, she must assume the identity of a noblewoman. She chooses Marie d’Odette: famed for her beauty, a rumored candidate for future queen…and Odile’s childhood-friend-turned-sworn-enemy. With her father’s help, Odile transforms Marie into a swan and takes her place at court. But when the king is brutally murdered and her own brother is accused, her plans are thrown into chaos. Desperate to free her brother, Odile is forced to team up with none other than elegant, infuriating Marie, the girl she has cursed…and the girl she can’t seem to stop thinking about despite her best efforts. To make matters worse, there are whispers that the king’s murder was not at the hands of man, but beast. Torn between loyalty to her father and her growing feelings for Marie, Odile becomes tangled in a web of treachery and deceit. To save her kingdom, she must find the true path to magic…and find the real killer before they—or it—strikes again.

**Important time note:** Please plan on arriving between 5:30 and 6:00 as the elevators lock after 6 and you'll need to message us and we'll need to come get you. The building address is 4450 Bridge Park The entrance is 6620 Mooney St, Suite 400 **Abstract** TBD **YouTube Link** TBA
