• 2026-08-22 The smartest man on the cinder #culture#vibecoding Ata Kuyumcu

  Anti-AI anger runs hotter than its object. A Jungian read: shadow projection, a threatened persona, and both camps picturing the same burnt world.

• 2026-08-17 Sixty days of dailyprog #programming#vibecoding#web Ata Kuyumcu

  Two months of dailyprog analytics: 1,589 visitors, 470 passing solves, three 30-day streaks, and half the traffic leaving without firing an event.

• 2026-08-16 Open-sourcing a puzzle site without leaking the puzzles #devops#programming#culture Ata Kuyumcu

  I open-sourced dailyprog under AGPL-3.0. The hard part wasn't the license, it was that the puzzle catalogue and hidden tests are the answers, so they can't be public.

• 2026-08-12 Nobody has reached the bottom (yet) #games#javascript#vibecoding#web Ata Kuyumcu

  Three days of analytics from the dungeon under this blog: 1,040 entries, 530 sessions that met a stranger, 683 deaths, and a floor at depth 13 that nobody has seen at the time of writing.

• 2026-08-10 There's a dungeon under this blog #games#javascript#networking#vibecoding Ata Kuyumcu

  A multiplayer dungeon crawler hidden in a static site: WebRTC with no server, a world derived from the date, and monsters run by whoever has the lowest peer id.

• 2026-07-31 Tests for a PDF #testing#devops Ata Kuyumcu

  My CV has a test suite, because the first thing that reads a CV is a parser. Four checks, one ATS workaround I measured and couldn't justify, and one assertion that has never run once.

• 2026-07-18 The fediverse was right #culture#web#vibecoding Ata Kuyumcu

  Federated services are the only escape from corporate platforms and lonely self-hosting. ActivityPub works. Git forges are next. AI just made protocols cheap enough to iterate on.

• 2026-07-14 The dailyprog puzzle safety net #devops#programming#vibecoding Ata Kuyumcu

  A nightly CI job checks whether tomorrow's dailyprog puzzle exists; if not, it generates one, runs it through the same tests a manual commit would, and deploys it before midnight.

• 2026-07-10 Adding Go to a browser code runner #wasm#go#programming Ata Kuyumcu

  Adding Go to a sandboxed code runner: why the GOOS=js path hangs inside a V8 isolate, and how Yaegi compiled to WASI turned out to be the clean path.

• 2026-07-01 Building a passive Ethernet tap #hardware#networking#security Ata Kuyumcu

  Cloning the Throwing Star LAN tap on mini breadboards for €10 to see how chatty my smart TV is. No power, no software, physically receive-only.

• 2026-06-29 Generating coding puzzles with LLMs #programming#vibecoding#ai Ata Kuyumcu

  How dailyprog generates a fresh coding puzzle every day: a legally safe corpus, an LLM-built ontology, and a repair loop that runs real code.

• 2026-06-26 Revisiting server hardening #devops#security Ata Kuyumcu

  Six things my Linux hardening baseline missed, found on a fresh Debian 13 VPS, plus post-quantum SSH key exchange in one config line.

• 2026-06-10 Rebuilding my blog with machines, for machines #culture#web#vibecoding Ata Kuyumcu

  I rebuilt this blog with the same URLs and markup, plus a JSON-LD graph on every page and microformats on every element. For the machines.

• 2026-06-05 Autopsying a SanDisk Extreme SSD #devops#hardware Ata Kuyumcu

  A dead SanDisk Extreme Portable SSD, taken apart: the bridge chip answers, the NVMe behind it is gone, and the warranty runaround.

• 2026-05-27 Balancing an MMO economy with a black market #games Ata Kuyumcu

  Every item in Albion Online is player-crafted, yet mobs drop loot. The Black Market merchant squares that circle, and the design generalises.

• 2026-04-23 Hardening a fresh Linux install #devops#security Ata Kuyumcu

  The baseline I apply to every fresh VPS: non-root user, SSH lockdown, UFW, fail2ban, unattended upgrades, and the Docker firewall hole.

• 2021-02-25 Building custom commands in Bevy #rust#games Ata Kuyumcu

  Using Rust extension traits to add your own commands to Bevy's Commands struct. Written for Bevy 0.4 in 2021; the pattern still holds.

• 2019-10-22 Setting up remote backups with Restic #devops Ata Kuyumcu

  Encrypted, incremental backups with restic and Backblaze B2: the pricing model's API-call gotchas, setup, pruning, and automation.

• 2018-11-20 Working through the SICP exercises #plt#lisp#compsci Ata Kuyumcu

  Solutions and notes for the first ten exercises of SICP chapter 1.

• 2018-10-01 I did a few things at STM CTF 2018 Prelims #security#python Ata Kuyumcu

  Writeups for three challenges from the STM CTF 2018 prelims: DiEfAyAr, Rengarenk String, and Matruşka.

• 2018-03-01 I did a thing at Harekaze CTF 2018 #security#cryptography#python Ata Kuyumcu

  One crypto challenge from Harekaze CTF 2018: gacha, an RSA service solved while waiting for another CTF to start.

• 2017-12-04 I did a thing at TU CTF 2017 #security#cryptography#python Ata Kuyumcu

  The Neverending Crypto at TU CTF 2017: scripting a Caesar cipher breaker in Python fast enough to keep up with the rounds.
