Byte-sized insights into software development, AI, and the future of technology.
Why I got curious about Post-Quantum crypto (and what broke) I went looking at post-quantum cryptography because I wanted something concrete I could ...
The problem I ran into on a hybrid cluster I was building a hybrid (on‑prem + public cloud) environment where services needed egress (outbound netwo...
The problem I tripped over: “Same Dockerfile, different image” I was running a CI/CD pipeline where every PR kicked off a Docker build, then pushed a...
Why I got obsessed with “receipt memos” I stumbled into a weird bug class while building a decentralized provenance system: the smart contract would ...
I got pulled into a weird smart-manufacturing problem after a weekend of tinkering: tiny, non-obvious defects on circuit boards that look like nothing...
The bug that sent me down a rabbit hole I recently tried to validate a CRYSTALS-Dilithium signature (a post-quantum signature scheme standardized by...
I fell into this rabbit hole because I kept seeing the same annoying pattern in my homelab: my CI pipeline would mint short-lived API tokens, those to...
The problem I ran into I built a hybrid webhook pipeline that had to accept payment events from two different SaaS vendors, then forward them to int...
I ran into a weird failure mode while building a predictive model for “will this checkout fail today?” The data looked fine in batch, but during real-...
The weekend problem I couldn’t stop thinking about I was building an “AI assistant” that had to call internal tools (like fetching account metadata)...
The weekend problem I kept running into I was building a small system that scheduled short background jobs. Nothing fancy—just a single service, mul...
I ran into a weird but real problem while tinkering with blockchain infrastructure: node operators (including me) often have “clean” logs—until you tr...
I got tired of treating “threat intelligence” like a blob of text—some feeds said “APT29”, others said “malware family”, and in practice my SOC (secur...
The itch that started this I kept seeing “audit trails” in DeFi described as events in logs—and every time I dug deeper, I found the same mismatch: ...
I ran into a maddening problem while wiring up signed webhooks: the signature verification would randomly fail even though the “same” payload was bein...
Building a SCD Type 2 “Event-Time Merge” for Late Arriving Clickstream in dbt and Snowflake The problem that pulled me into this niche is simple: cl...
The problem I chased: a sudden 10x query spike in real-time metrics I hit a performance cliff in a real-time analytics pipeline that joins event dat...
The bug I chased for a week: “learning” that was really hardware drift I was experimenting with a tiny hybrid quantum-classical system: a classical ...
Last year I got bitten by a bug that “couldn’t possibly happen”: timers were firing, yet the system behaved like they weren’t. It turned out I was usi...
The provenance problem that kept bothering me I kept running into the same failure mode when building “digital provenance” systems: I could store ev...
I hit a fun (and annoying) problem while building a service that stores user edits as a stream of CRDT (Conflict-free Replicated Data Types) operation...
The bug I couldn’t explain: “Same event, different features” I ran a real-time feature pipeline for an AI model and watched accuracy slowly degrade o...
I ran into a bug that looked “random” in production: a UI button sometimes didn’t update, but only when users clicked quickly. Locally it was fine. In...
I got obsessed with a very specific workflow bug: every time my team exported an OpenAPI spec into Terraform-friendly artifacts, the “glue” logic live...
The weird problem I ran into: “same event” across chains I was building a small “digital provenance” system where an event—like “sensor reading X is ...
The weird problem I ran into I was testing a small drone camera pipeline over a cellular link (5G/6G integration in the real world, not in a lab dia...
The weird problem I ran into I was building an ETL pipeline that reads objects from one provider (S3-compatible storage) and writes into another—acr...
Why I got obsessed with “prompt tampering” I hit a weird problem while building a small generative workflow: two prompts that looked identical produc...
I stumbled into a weird corner of software supply chain security while debugging a “perfectly signed” release that still felt untrustworthy: the signa...
I got curious about something that’s annoyingly under-explained in DeFi: how to build a time-weighted average price (TWAP) oracle without trusting a c...
I got curious about a very specific failure mode in enterprise Retrieval-Augmented Generation (RAG): even when the retriever finds the “right” clauses...
The problem that got me curious I hit a weird failure in a CI pipeline that “looked secure” on paper: the pipeline was verifying artifacts, but it w...
The problem I ran into: “green” builds that later explode I recently helped wire a CI/CD pipeline for a distributed cloud platform, and everything lo...
The problem I stumbled into I spent a weekend trying to wire an ERC4626 vault into a DeFi portfolio and then feed its “share price” into an Aave v3 ...
The problem I stumbled into I got hooked on spatial computing because it lets you make digital content react to the real world. The part that surpri...
Building a Streaming “Monotonic Timestamp” Guardrail in Kafka Connect A weird class of incidents kept biting me in real-time pipelines: event times ...
Edge Vision for Predicting Conveyor Belt Tear Using Tiny YOLOv8 and IMU Correlation A couple weekends ago I got pulled into a frustrating smart-manu...

The problem I wanted to solve I once had to prove that a printed, scanned receipt image hadn’t been altered between a vendor’s laptop and an offline ...
The bug I chased: “login works on one subdomain, breaks on the other” I ran into a weird authentication failure while building a setup like this: - ...
I ran into a weird CI/CD failure that looked like an “auth problem,” but it wasn’t. The symptoms were consistent: GitHub Actions would authenticate to...
I got curious about a super specific failure mode in smart manufacturing: microstalls on a CNC spindle—those tiny hesitations that don’t trip the obvi...
