<!-- SC_OFF -->In order to understand how CPUs work internally I decided to build a small 16-bit CPU emulator entirely in Kotlin. It includes: A custom ISA (RISC/MIPS-inspired), Registers, Stack, Flags Instruction encoding/decoding ALU operations, branching and simple assembler I also wrote two detailed blog posts explaining the whole process step-by-step: 👉 Part 1 - Understanding how a CPU works: https://bloder.io/cpu-from-scratch-part-1 👉 Part 2 - Using Kotlin to create a CPU emulator: https://bloder.io/cpu-from-scratch-part-2 And here’s the full source code: 👉 https://github.com/bloderxd/kotlin-cpu <!-- SC_ON --> submitted by /u/_Bloder (https://www.reddit.com/user/_Bloder)

Using CEL's now() to enforce dependency cooldown periods - block packages published in the last N hours
https://www.reddit.com/r/programming/comments/1sbb7jv/using_cels_now_to_enforce_dependency_cooldown/

<!-- SC_OFF -->Supply chain attacks often rely on speed that is publish a malicious version, let automated builds pull it before detection catches up. One defense is a cooldown period : refuse any dependency published within the last N hours. CEL (Common Expression Language) doesn't expose now() by default since it's designed to be hermetic. This article actually walks through registering a custom now() function binding that returns the current UTC timestamp, using duration arithmetic to compare against package_published_at, and using the has() macro to handle packages so new they haven't been indexed yet - which is the edge case that will bite you if you miss it. <!-- SC_ON --> submitted by /u/BattleRemote3157 (https://www.reddit.com/user/BattleRemote3157)

I implemented Raft, a KV store, and a sharded system in Go (MIT 6.5840)
https://www.reddit.com/r/programming/comments/1sbdk50/i_implemented_raft_a_kv_store_and_a_sharded/

<!-- SC_OFF -->I recently completed the labs from MIT 6.5840 Distributed Systems and implemented everything in Go, including: Raft consensus algorithm A replicated Key/Value store A sharded KV system with dynamic reconfiguration The implementation focuses a lot on concurrency and failure handling: goroutines for RPC handling and background tasks channels for coordination between Raft and the state machine dealing with unreliable networks (dropped / delayed / out-of-order RPCs) Some interesting challenges: ensuring commitIndex never goes backward under out-of-order RPC responses handling retries safely with client/request IDs (idempotency) keeping deduplication state consistent across snapshots and shard transfers I wrote a detailed README explaining both the design and the tricky edge cases I encountered. <!-- SC_ON --> submitted by /u/am0123 (https://www.reddit.com/user/am0123)
