https://itobey.dev/ Ten years of first-hand fixes for problems that had no answer online yet: DevOps, self-hosting, smart home, and whatever else broke. en Sun, 23 Aug 2026 09:00:00 GMT https://itobey.dev/playlist-mirror-copying-youtube-channels-into-your-own-playlist/ https://itobey.dev/playlist-mirror-copying-youtube-channels-into-your-own-playlist/ Sun, 23 Aug 2026 09:00:00 GMT YouTube has no way to turn a channel into a playlist, or to copy one you don't own. Playlist Mirror does it for you, over as many days as it takes. https://itobey.dev/fddb-exporter-web-ui-trends-and-mcp-server/ https://itobey.dev/fddb-exporter-web-ui-trends-and-mcp-server/ Thu, 13 Aug 2026 09:00:00 GMT The Flutter app is gone, replaced by a web UI you can install as a PWA — plus a Trends view, no more v1 API, and an MCP server for your diary. https://itobey.dev/openclaw-youtube-summary-skill/ https://itobey.dev/?p=1062 Sat, 31 Jan 2026 11:16:41 GMT Running an AI agent on a VPS means YouTube blocks its IP. Here's the skill I built to summarize videos anyway — and why the agent itself is overhyped. https://itobey.dev/running-soapui-tests-automatically-in-a-gitops-argo-cd-deployment-pipeline/ https://itobey.dev/?p=1049 Tue, 30 Dec 2025 18:22:08 GMT How I run SoapUI integration tests as an Argo CD PostSync hook — custom TestRunner image, projects pulled from Artifactory, one Kubernetes Job per deploy. https://itobey.dev/re-release-of-fddb-exporter-app/ https://itobey.dev/?p=1043 Sun, 07 Sep 2025 08:10:52 GMT The Flutter app broke when I redesigned the backend. It's rebuilt against the new REST API, with an APK on GitHub releases if you'd rather not build it. https://itobey.dev/connecting-home-assistant-mcp-and-lm-studio/ https://itobey.dev/?p=1038 Tue, 19 Aug 2025 22:35:59 GMT LM Studio never negotiates SSE, so Home Assistant's MCP server rejects it. The fix is a small stdio-to-SSE bridge sitting between the two. https://itobey.dev/fddb-exporter-now-with-mongodb-full-entry-retrieval-and-rest-api/ https://itobey.dev/?p=1023 Tue, 08 Oct 2024 19:17:20 GMT A full redesign: MongoDB storage, every diary entry instead of daily totals, a REST API with keyword search, and login without hunting for a cookie. https://itobey.dev/automating-script-execution-on-program-exit/ https://itobey.dev/?p=1010 Mon, 01 Jan 2024 15:08:27 GMT A cronjob every 30 minutes still lost notes when I shut down early. Windows' audit log can trigger the git push the moment Obsidian actually closes. https://itobey.dev/adding-a-home-assistant-timer-to-stream-deck/ https://itobey.dev/?p=995 Tue, 26 Sep 2023 13:18:35 GMT Three Home Assistant timers on one Stream Deck button: washing machine, dishwasher and a custom countdown, all visible without opening an app. https://itobey.dev/linting-dockerfiles-in-jenkins-pipelines-with-hadolint/ https://itobey.dev/?p=987 Sun, 13 Aug 2023 15:49:03 GMT Hadolint in a Jenkins pipeline: the Groovy that runs it, how to fail the build on findings, tuning the rules, and an Alpine quirk that cost me an hour. https://itobey.dev/building-a-mobile-app-with-flutter-for-the-fddb-exporter-backend/ https://itobey.dev/?p=954 Sat, 11 Feb 2023 15:35:16 GMT FDDB Exporter needed a front end, so I built one in Flutter - my first mobile app, what the backend had to expose, and what Flutter was like. https://itobey.dev/running-background-scripts-in-windows-without-terminal-pop-up/ https://itobey.dev/?p=865 Tue, 20 Dec 2022 09:43:39 GMT Windows flashes a terminal window every time a scheduled script runs, stealing focus from whatever is fullscreen. wscript and pythonw stop it. https://itobey.dev/creating-self-signed-keystores-in-openshift-kubernetes-to-re-encrypt-spring-boot-apps/ https://itobey.dev/?p=852 Sat, 10 Dec 2022 14:53:43 GMT Two ways to get a pkcs12 or JKS keystore into a Spring Boot pod on OpenShift - cert-manager and the built-in service signer - and when each one fits. https://itobey.dev/restoring-original-ip-cloudflare-wordpress-kubernetes-traefik/ https://itobey.dev/?p=839 Sun, 06 Nov 2022 16:48:48 GMT Behind Cloudflare and Traefik every visitor looked like the same internal IP. Fixing it takes the traffic policy, trusted IPs and one Apache module. https://itobey.dev/reset-admin-password-on-teamspeak3-docker/ https://itobey.dev/?p=821 Mon, 18 Jul 2022 17:16:59 GMT The Teamspeak 3 admin password is shown once at startup and mine stopped working. There is an undocumented way to reset it on the Docker image. https://itobey.dev/export-nutritional-data-diary-from-fddb-info/ https://itobey.dev/?p=781 Sat, 28 Aug 2021 15:59:49 GMT Calories stopped being enough once I started tracking macros, so the FDDB exporter grew to pull the whole diary. Superseded by the MongoDB rewrite. https://itobey.dev/project-smart-home-dashboard/ https://itobey.dev/?p=767 Mon, 02 Aug 2021 19:28:13 GMT A short note on the e-ink smart home dashboard: an Inkplate 10, Home Assistant rendering a Lovelace view to JPG, and how it went down on Reddit. https://itobey.dev/datadog-as-an-intermediary-for-gathering-metrics/ https://itobey.dev/?p=743 Sat, 31 Jul 2021 18:49:47 GMT I wanted metrics from every device without opening a port anywhere. Datadog collects them, and a small client pulls them back out through its API. https://itobey.dev/specific-calendar-events-crash-the-home-assistant-integration/ https://itobey.dev/?p=734 Sun, 25 Jul 2021 12:38:46 GMT One malformed calendar entry takes out the Home Assistant calendar integration for a whole day. What the event looks like, and how to find it. https://itobey.dev/inkplate-10-not-displaying-grayscale-jpg-image/ https://itobey.dev/?p=641 Sun, 11 Jul 2021 17:03:35 GMT The Inkplate 10 showed the example images fine and refused my dashboard JPG. The problem is how the file is encoded, not the image itself. https://itobey.dev/creating-self-signed-wildcard-certificates-for-modern-browsers/ https://itobey.dev/?p=630 Sun, 30 May 2021 19:45:53 GMT Chrome 58 stopped accepting commonName, so my self-signed wildcard certificate broke. Here is the OpenSSL config that produces one browsers trust. https://itobey.dev/wildcard-certificates-dns-challenges-and-traefik-in-kubernetes/ https://itobey.dev/?p=610 Wed, 19 May 2021 14:23:48 GMT A wildcard certificate needs a DNS challenge, which means handing an API token to Traefik. The Cloudflare setup, and the trade-off it makes. https://itobey.dev/redirect-http-to-https-traefik-middleware-kubernetes/ https://itobey.dev/?p=603 Sat, 15 May 2021 10:19:39 GMT A global Traefik redirect breaks ACME HTTP challenges. A middleware lets you redirect only the services you meant to and leave the rest alone. https://itobey.dev/diy-smart-home-sensor-esp32-dht22/ https://itobey.dev/?p=579 Sun, 04 Apr 2021 16:32:22 GMT An ESP32 and a DHT22 publishing temperature and humidity over MQTT into Home Assistant - the wiring, the code, and why I took it apart again. https://itobey.dev/export-daily-calories-from-fddb-to-a-database/ https://itobey.dev/?p=574 Fri, 19 Mar 2021 17:17:27 GMT My first attempt at getting calorie data out of fddb.info into my own database for Grafana. Superseded since, but the scraping approach still holds. https://itobey.dev/subtract-subquery-constant-in-influxdb-grafana/ https://itobey.dev/?p=563 Sat, 27 Feb 2021 17:05:47 GMT InfluxDB will not subtract a constant returned by a subquery, so my FritzBox traffic graph stayed empty. Grafana can do the arithmetic instead. https://itobey.dev/read-external-influxdb-in-home-assistant-as-sensor/ https://itobey.dev/?p=553 Sat, 20 Feb 2021 16:43:34 GMT Running Home Assistant in plain Docker means no Supervisor and no add-ons. Reading an InfluxDB that lives outside it, as a sensor, still works. https://itobey.dev/connecting-telegraf-to-mosquitto-with-influxdb/ https://itobey.dev/?p=548 Sun, 14 Feb 2021 09:40:49 GMT Telegraf scraped my Mosquitto broker and got nothing back, with a config every tutorial said was right. The fix was one setting nobody mentions. https://itobey.dev/external-renderer-for-grafana-docker/ https://itobey.dev/?p=537 Sun, 07 Feb 2021 11:00:21 GMT Grafana 7 dropped the bundled image renderer and the plugin will not install through an environment variable. Run it as its own container instead. https://itobey.dev/android-backups-nextcloud-vs-resilio-sync/ https://itobey.dev/?p=515 Mon, 20 Jul 2020 19:35:31 GMT I needed encrypted Android folder backups that never leave the LAN. Resilio Sync on a Pi does it well; Nextcloud and FolderSync were far slower. https://itobey.dev/checking-the-availability-of-an-encrypted-volume-ft-pushbullet-and-pi-hole/ https://itobey.dev/?p=511 Sat, 11 Jul 2020 10:23:28 GMT A LUKS volume needs its passphrase by hand after every reboot. A small check plus Pushbullet tells me when it is not mounted, and why Pi-hole matters. https://itobey.dev/web-airmore-com-not-loading-correctly-anymore/ https://itobey.dev/?p=505 Sat, 06 Jun 2020 20:30:46 GMT web.airmore.com started rendering as bare HTML with no scripts or stylesheets. The browser console says why, and the fix is on your side. https://itobey.dev/inputs-from-teamviewer-to-vmware-horizon-not-working/ https://itobey.dev/?p=378 Sat, 30 Nov 2019 09:53:21 GMT A TeamViewer session on a host running VMWare Horizon swallows every keystroke and click. The cause is where the Horizon client puts keyboard focus. https://itobey.dev/migrate-teamspeak-3-server-to-docker/ https://itobey.dev/?p=334 Sat, 09 Nov 2019 15:51:51 GMT Moving a Teamspeak 3 server from SQLite into a Docker container with MariaDB, including the database conversion the official image does not do for you. https://itobey.dev/restore-mails-from-removed-thunderbird-account/ https://itobey.dev/?p=323 Fri, 25 Oct 2019 19:28:35 GMT Removing an account in Thunderbird does not delete its mail. If the profile files are still on disk, the messages can be brought back into a new account. https://itobey.dev/docker-hostname-resolution-not-working/ https://itobey.dev/?p=319 Sat, 14 Sep 2019 08:05:05 GMT Container hostnames will not resolve on Docker's default bridge network. It is not a bug, and the fix is one line: use a user-defined network. https://itobey.dev/soapui-authorization-settings-present-although-disabled/ https://itobey.dev/?p=288 Sat, 19 Jan 2019 16:53:42 GMT SoapUI keeps applying authorization settings to a request after you switch them off, which quietly breaks it. Reproduced on 5.2.1 and 5.4.0. https://itobey.dev/undo-onenote-2016-app-replacement/ https://itobey.dev/?p=272 Wed, 12 Sep 2018 09:00:36 GMT Office 365 removed OneNote 2016 and left the app in its place. It can be reinstalled, and this is where Microsoft keeps the installer. https://itobey.dev/benchmark-intel-cpu-8700k-vs-3570k/ https://itobey.dev/?p=247 Thu, 05 Apr 2018 12:18:26 GMT Synthetic scores and real game benchmarks for the i5-3570k against the i7-8700k, because nobody had compared these two on anything but 3DMark. https://itobey.dev/websites-not-loading-using-vpn/ https://itobey.dev/?p=227 Fri, 28 Jul 2017 22:29:32 GMT Connected to a VPN, with a working connection, and some sites simply will not load. It is almost always the MTU - here is how to prove it. https://itobey.dev/mitm-sony-ht-xt2-update-failures/ https://itobey.dev/?p=201 Sat, 11 Mar 2017 13:32:46 GMT My Sony HT-XT2 refused every firmware update with a server communication error, so I put myself in the middle of the connection to find out why. https://itobey.dev/login-snapchat-rooted-bluestacks/ https://itobey.dev/?p=182 Fri, 02 Dec 2016 17:51:39 GMT Snapchat refuses to log in on a rooted device and removing Xposed no longer helps. Bluestacks can produce a login you then restore onto the phone. https://itobey.dev/password-openvpn-cert/ https://itobey.dev/?p=176 Mon, 24 Oct 2016 18:08:18 GMT Most OpenVPN tutorials pick either certificates or credentials. This adds a password on top of the certificate, using a module the server already ships. https://itobey.dev/fix-python-error-lets-encrypt-certificate-renewal/ https://itobey.dev/?p=163 Thu, 14 Jul 2016 19:42:12 GMT Renewing a Let's Encrypt certificate threw a Python error instead of finishing. Two steps: get the certificate renewed, then stop the error returning. https://itobey.dev/youtube-videos-javascript/ https://itobey.dev/?p=149 Wed, 08 Jun 2016 19:07:13 GMT A snippet that clicked YouTube's Load More button until a whole channel was listed. YouTube changed how it loads videos, so this no longer works. https://itobey.dev/ssl-webservices-proxy-auth-soapui/ https://itobey.dev/?p=128 Sat, 05 Mar 2016 09:32:46 GMT SoapUI's proxy settings do not survive an HTTPS request through a corporate proxy. Fiddler shows what is missing and where to put the header instead. https://itobey.dev/display-rating-in-foobar-search-results/ https://itobey.dev/?p=116 Mon, 08 Feb 2016 21:33:20 GMT foobar2000 rates songs but will not show the rating in search results. One title-formatting expression puts the stars back where you can see them. https://itobey.dev/establishing-a-noise-gate-for-skype/ https://itobey.dev/?p=87 Sat, 06 Feb 2016 16:07:50 GMT Skype has no activation threshold, so it transmits every hiss. Voicemeeter Banana sits in front of it as a noise gate - here is the routing. https://itobey.dev/dynamically-filling-requests-soapui-using-textfile/ https://itobey.dev/?p=34 Tue, 02 Feb 2016 21:45:55 GMT Only SoapUI Pro binds data sources, but a short Groovy script reads a text file and fires the same request a few hundred times with different IDs.
