I Needed a Private Sync Network for My Journals — So I Tried Both The thing that broke my patience with raw WireGuard wasn’t the first node or even the third — it was adding a VPS to a mesh that already had my home server and laptop talking to each other. Suddenly I’m juggling … Read more
I Needed a Home Server OS and Couldn’t Stop Second-Guessing Myself The thing that sent me down this rabbit hole wasn’t a technical problem — it was a Reddit thread where someone asked “Ubuntu or Fedora for a home server?” and every single reply was “just use Ubuntu.” No explanation. No trade-offs. Just vibes. I’d … Read more
The Error That Wastes Half Your Afternoon The worst CI failure mode isn’t a red build — it’s a build that looks like it never existed. You push a tag like v2.4.1, watch the CircleCI dashboard for a few seconds, and see… nothing. Not a failed pipeline. Not a warning. Just the tag sitting there, … Read more
The Problem That Sent Me Down This Rabbit Hole The thing that caught me off guard was how silent the failure was. My Lambda function was trying to connect to an MSK cluster, the connection timed out, and the only thing in CloudWatch was org.apache.kafka.common.errors.SaslAuthenticationException: Authentication failed. No principal name. No hint about which credential … Read more
The Problem That Made Me Actually Care About Storage Engines The thing that broke my comfortable ignorance about storage engines was a pipeline ingesting sensor telemetry — about 50,000 inserts per second into a PostgreSQL 15 cluster. The hardware wasn’t cheap: NVMe drives, 32 cores, 128GB RAM. Didn’t matter. Around 40k inserts/sec, write latency would … Read more
The Problem Nobody Warns You About The thing that caught me off guard wasn’t the query latency — it was the storage invoice. We had a working Elasticsearch cluster, decent relevance tuning, p95 query times under 200ms. Then we crossed 100M documents and the disk bill tripled inside of two billing cycles. Not doubled. Tripled. … Read more
Why I Built This (And Why You Should Too) I was three hours deep into a Docker networking debug session — containers couldn’t reach each other, docker network inspect was giving me nothing useful — and I had this uncomfortable realization: I was treating Docker like magic. I knew the commands. I had no idea … Read more
The Problem: 3D Tours Used to Require a $5,000 Camera and a Production Team The thing that surprised me most when I first tried shooting a 3D tour with my iPhone 13 Pro was how fast it worked. I expected garbage — blurry depth maps, misaligned stitching, the usual “consumer tech trying to be pro” … Read more
I Needed a Home Server OS and Couldn’t Stop Second-Guessing Myself The machine I was setting up wasn’t impressive — a decommissioned Dell OptiPlex 7050 with 16GB RAM, a 500GB NVMe I had lying around, and an old spinning disk I repurposed for media. The workload: Plex with hardware transcoding, Nextcloud for file sync, Pi-hole … Read more
The Situation That Made Me Build a Real Patching Workflow The Slack message came in at 6:47 AM on a Tuesday. CVE-2024-1086 — a use-after-free in the netfilter subsystem that gives local users a path to root. My servers were running kernel 6.1.x. None of them were patched. I had 40 production boxes spread across … Read more
