What if TUI regions were Erlang-style actors?
https://www.reddit.com/r/programming/comments/1q63eio/what_if_tui_regions_were_erlangstyle_actors/

<!-- SC_OFF -->I experimented treating each terminal UI region as an independent actor with message-passing and supervision. Yes overkill for simple TUIs, but more complex tuis have overlapping problems: Isolation: Each region owns its state. No shared mutables, no "where did this change?" debugging. Explicit data flow: When the footer repaints, I know which message triggered it. Supervision: If a region crashes, a supervisor restarts it. App continues. Matters for long-running dashboards or other apps like that. Children never write to the terminal directly - they send render requests to the parent. Single-writer semantics enforced by architecture. Wrote it up on my blog with source code to fiddle around with: https://www.rodriguez.today/articles/reactive-tui-architecture-with-actors Curious if others have applied distributed systems patterns to UI problems? <!-- SC_ON --> submitted by /u/rrrodzilla (https://www.reddit.com/user/rrrodzilla)

Sandboxes: a technical breakdown of containers, gVisor, microVMs, and Wasm
https://www.reddit.com/r/programming/comments/1q69bxn/sandboxes_a_technical_breakdown_of_containers/

<!-- SC_OFF -->Hi everyone! I wrote a deep dive on the isolation boundaries used for running untrusted code, specifically in the context of AI agent execution. The motivation was that "sandbox" means at least four different things with different tradeoffs, and the typical discussion conflates them. Technical topics covered: - How Linux containers work at the syscall level (namespaces, cgroups, seccomp-bpf) and why they're not a security boundary against kernel exploits - gVisor's architecture: the Sentry userspace kernel, platform options (systrap vs KVM), and the Gofer filesystem broker - MicroVM design: KVM + minimal VMMs (Firecracker cloud-hypervisor, libkrun) - Kata Containers - Runtime sandboxes: Wasm's capability model, WASI preopened directories, V8 isolate boundaries It's an educational piece, just synthesizing what I learned building this stuff. I hope you like it! <!-- SC_ON --> submitted by /u/BeowulfBR (https://www.reddit.com/user/BeowulfBR)

Solving Weighted Random Sorting at Scale (O(N log N) approach)
https://www.reddit.com/r/programming/comments/1q6f2ez/solving_weighted_random_sorting_at_scale_on_log_n/

<!-- SC_OFF -->I recently wrote about a routing challenge I faced at Microsoft regarding weighted random sorting for fail-over lists. While many implementations use an iterative "pick and remove" loop, these are often O(N2 log N) and scale poorly. I've detailed how to use the Efraimidis-Spirakis algorithm to perform a mathematically perfect weighted sort in a single pass. This is particularly useful for anyone building load balancers, traffic dispatchers, or systems dealing with streaming data.

I got paid minimum wage to solve an impossible problem (and accidentally learned why most algorithms make life worse)
https://www.reddit.com/r/programming/comments/1q6fyhf/i_got_paid_minimum_wage_to_solve_an_impossible/

<!-- SC_OFF -->I was sweeping floors at a supermarket and decided to over-engineer it. Instead of just… sweeping… I turned the supermarket into a grid graph and wrote a C++ optimizer using simulated annealing to find the “optimal” sweeping path. It worked perfectly. It also produced a path that no human could ever walk without losing their sanity. Way too many turns. Turns out optimizing for distance gives you a solution that’s technically correct and practically useless. Adding a penalty each time it made a sharp turn made it actually walkable. But, this led me down a rabbit hole about how many systems optimize the wrong thing (social media, recommender systems, even LLMs). If you like algorithms, overthinking, or watching optimization go wrong, you might enjoy this little experiment.

Why I hate WebKit: A (non) love letter from a Tauri developer

<!-- SC_OFF -->After catching my third // TODO: implement this later in production code written by an AI assistant, I decided to build a tool to catch these issues before they ship. AntiSlop is a CLI tool that acts as a safety net for AI-generated code. It scans your codebase for the "lazy artifacts" that LLMs often leave behind: Stub functions and empty implementations console.log / print() debugging statements Hedging comments like "temporary", "for now", "simplified" Unhandled errors in critical paths The key differentiator: it uses tree-sitter AST parsing instead of regex, so it actually understands code structure and ignores string literals. Supports Rust, Python, JavaScript/TypeScript, and Go. Install: cargo install antislop npm install -g antislop GitHub: https://github.com/skew202/antislop Would love feedback from others dealing with AI code in production.
