on an underpowered NAS, I offloaded transcription to Cloudflare Workers AI and article cleanup to LiteLLM, turning the NAS into an automation hub with its own web player for listening, searching, and reading.https://chengyu.eu/posts/dsm-7-4-upgrade-storage-efficiency/Mon, 20 Jul 2026 08:00:54 +0000https://chengyu.eu/posts/dsm-7-4-upgrade-storage-efficiency/Community reports convinced me DSM 7.4 was stable enough to risk on a production NAS — the upgrade went flawlessly, but the one feature I actually wanted, Storage Efficiency, turned out to be locked out of older hardware entirely.https://chengyu.eu/posts/dji-4g-module-new-tricks/Fri, 10 Jul 2026 07:55:28 +0000https://chengyu.eu/posts/dji-4g-module-new-tricks/A DJI 4G module identifies itself with a private USB ID that Linux won’t drive properly — spoofing it as a generic Quectel EC25 unlocked full modem support, and it ended up running SMS management on an OpenWrt router instead of the NAS.https://chengyu.eu/posts/immich-3-upgrade-ds218plus/Thu, 09 Jul 2026 18:00:12 +0000https://chengyu.eu/posts/immich-3-upgrade-ds218plus/The official 3.0 release with built-in AI photo editing was tempting enough to risk an upgrade on a stable NAS setup — the process went smoothly, with the only surprise being a slow first-boot database migration that looked like a crash.https://chengyu.eu/posts/podsync-po-token-crash-troubleshooting/Thu, 09 Jul 2026 14:08:34 +0000https://chengyu.eu/posts/podsync-po-token-crash-troubleshooting/One feed kept crashing Podsync with a cryptic ‘bad format string’ error — three wrong turns later, the real fix meant switching Docker images and realizing YouTube’s PO Token wasn’t actually being generated at all.https://chengyu.eu/posts/vps-breach-to-backup-system/Fri, 03 Jul 2026 10:00:10 +0000https://chengyu.eu/posts/vps-breach-to-backup-system/After cleaning up malware off a VPS, the bigger realization was that defense alone isn’t enough without recoverability — so I built a four-layer backup system covering local snapshots, scheduled automation, off-site NAS sync, and recovery documentation.https://chengyu.eu/posts/vps-security-incident-reflection/Thu, 02 Jul 2026 12:37:21 +0000https://chengyu.eu/posts/vps-security-incident-reflection/A cryptomining-style trojan ran undetected on my Oracle Cloud VPS for nearly 20 days — the real lesson wasn’t fixing that one box, but realizing monitoring itself needs to be monitored.https://chengyu.eu/posts/dropbox-to-seafile-nas-knowledge-base/Mon, 15 Jun 2026 08:00:48 +0000https://chengyu.eu/posts/dropbox-to-seafile-nas-knowledge-base/After bringing photos home to Immich, files were next — Seafile replaced Dropbox for syncing, then got paired with Open WebUI, RAG, and LiteLLM to turn a plain file store into a searchable, AI-queryable knowledge base.https://chengyu.eu/posts/google-photos-icloud-to-immich-migration/Mon, 15 Jun 2026 08:00:36 +0000https://chengyu.eu/posts/google-photos-icloud-to-immich-migration/Photos scattered across Google Photos, iCloud, a Huawei phone, a DJI drone, and action cameras finally got consolidated into one self-hosted, deduplicated Immich library — though my aging Synology DS218+ is starting to show its limits.https://chengyu.eu/posts/autoreel-nas-media-organizer/Sun, 24 May 2026 22:00:08 +0000https://chengyu.eu/posts/autoreel-nas-media-organizer/Built a small self-hosted tool that watches a download folder, identifies movies and TV episodes, and renames/moves them into an Emby/Jellyfin/Plex-friendly structure — deliberately conservative, preferring to flag unrecognized files rather than guess and rename wrong.https://chengyu.eu/posts/podsync-monitoring-alerts/Tue, 05 May 2026 18:00:08 +0000https://chengyu.eu/posts/podsync-monitoring-alerts/Self-hosted Podsync fails silently when YouTube cookies get rotated out — a simple log-scanning script paired with scheduled tasks now pushes an alert within 10 minutes, plus twice-daily download reports.https://chengyu.eu/posts/trendradar-information-feed-hub/Mon, 04 May 2026 21:00:13 +0000https://chengyu.eu/posts/trendradar-information-feed-hub/Too many English finance and tech RSS feeds to skim by hand — TrendRadar, an open-source aggregator, filters, translates, and summarizes them via AI, then pushes the results to Telegram.https://chengyu.eu/posts/fixing-podcast-rss-cover-image/Mon, 04 May 2026 20:00:08 +0000https://chengyu.eu/posts/fixing-podcast-rss-cover-image/One podcast pipeline’s cover art broke when its external image URL died; the fix was routing RSS cover URLs through a single local-file method, plus a couple of quality-of-life tweaks for a language-learning audio feed.https://chengyu.eu/posts/hermes-domain-isolation-optimization/Wed, 29 Apr 2026 10:00:06 +0000https://chengyu.eu/posts/hermes-domain-isolation-optimization/Investing talk kept leaking into work notes and vice versa — the fix was splitting Hermes into a router plus dedicated stock, work, diary, and life sub-assistants, each with its own knowledge base partition and a strict no-cross-referencing prompt.https://chengyu.eu/posts/podsync-cookie-troubleshooting-diary/Wed, 29 Apr 2026 09:00:07 +0000https://chengyu.eu/posts/podsync-cookie-troubleshooting-diary/Podsync started throwing YouTube bot-verification and rate-limit errors — the fix was exporting browser cookies into the container’s mounted data directory and wiring them into yt-dlp’s args.https://chengyu.eu/posts/trinity-ai-system-weekend-build/Mon, 20 Apr 2026 02:01:20 +0000https://chengyu.eu/posts/trinity-ai-system-weekend-build/A personal assistant on the home NAS, a home assistant tied into an investment system, and an intelligence-gathering agent on a VPS — three modules starting to work together as a real perception-cognition-action loop, not just a pile of tools.https://chengyu.eu/posts/litellm-model-routing-config/Sun, 19 Apr 2026 23:00:11 +0000https://chengyu.eu/posts/litellm-model-routing-config/A full writeup of the LiteLLM gateway config behind my AI stack — free NVIDIA NIM and OpenRouter models as the safety net, cheap paid models like DeepSeek V3 for daily use, and Claude Sonnet as an on-demand top-tier fallback.https://chengyu.eu/posts/hermes-synology-nas-deployment/Sun, 19 Apr 2026 22:00:12 +0000https://chengyu.eu/posts/hermes-synology-nas-deployment/After getting Hermes running on a VPS, I moved it to my Synology NAS instead so it could gradually gain access to household journal and investment data as an internal AI hub — and redesigned the model routing along the way.https://chengyu.eu/posts/hermes-new-ai-assistant-setup/Sun, 19 Apr 2026 01:00:07 +0000https://chengyu.eu/posts/hermes-new-ai-assistant-setup/OpenClaw’s buzz is fading and everyone’s talking about Hermes — its token compression alone (50%+, reportedly up to 70% in some cases) was reason enough to spin up a VPS and try it.https://chengyu.eu/posts/vibevoice-asr-tts-setup-diary/Sat, 18 Apr 2026 10:01:18 +0000https://chengyu.eu/posts/vibevoice-asr-tts-setup-diary/Setting up Microsoft’s VibeVoice to test audio-to-subtitle generation and text-to-speech: the ASR side (multi-speaker SRT generation) turned out production-ready, while TTS — especially Chinese — wasn’t there yet.https://chengyu.eu/posts/ubuntu-wol-shutdown-auto-restart-fix/Sat, 18 Apr 2026 09:00:08 +0000https://chengyu.eu/posts/ubuntu-wol-shutdown-auto-restart-fix/A GPU server configured for Wake-on-LAN would shut down cleanly, then reboot itself ~10 seconds later — the culprit was ACPI wakeup left enabled on the network card, letting ordinary LAN broadcast traffic trigger a wake, not just the magic packet.https://chengyu.eu/posts/openclaw-weekend-zero-cost-overhaul/Sat, 11 Apr 2026 17:33:00 +0000https://chengyu.eu/posts/openclaw-weekend-zero-cost-overhaul/When my free Google Cloud credits ran out and Gemini started rate-limiting, I rebuilt OpenClaw’s model chain into a three-tier free-and-cheap failover setup — and rethought which use cases were still worth the tokens.https://chengyu.eu/posts/openclaw-quiz-speed-optimization/Sun, 15 Mar 2026 00:04:00 +0000https://chengyu.eu/posts/openclaw-quiz-speed-optimization/Adding a quiz question was taking 2-3 minutes and getting slower over time — the fix was switching the data file from a JSON array to NDJSON so new items append in one line instead of a full rewrite.https://chengyu.eu/posts/openclaw-api-rate-limit-fix/Sat, 14 Mar 2026 22:00:47 +0000https://chengyu.eu/posts/openclaw-api-rate-limit-fix/Adding more API keys didn’t fix the slowdowns — the real issue was a key that existed in secrets but was never registered for failover, plus session pinning that kept using the same key after a restart.https://chengyu.eu/posts/openclaw-blog-wechat-automation/Mon, 23 Feb 2026 10:00:08 +0000https://chengyu.eu/posts/openclaw-blog-wechat-automation/From a rough idea in OpenClaw to a published blog post to a WeChat Official Account draft — with a VPS script standing in as the bridge and quietly fixing WeChat’s image hotlink problem along the way.https://chengyu.eu/posts/clawdbot-obsidian-apple-notes-integration/Thu, 12 Feb 2026 11:00:12 +0000https://chengyu.eu/posts/clawdbot-obsidian-apple-notes-integration/Voice in, an Obsidian note out, a blog post and short video out the other end automatically — plus Apple Notes, Google Sheets, and an email pipeline running hands-free.https://chengyu.eu/posts/hyonix-vps-expansion/Wed, 04 Feb 2026 22:00:21 +0000https://chengyu.eu/posts/hyonix-vps-expansion/A WSL2 dead end on an old Windows Server 1809 box turned into a pleasant surprise: one support ticket doubled the disk quota on a four-year-old VPS.https://chengyu.eu/posts/forcing-https-typecho-tencent-lighthouse/Wed, 28 Jan 2026 22:20:13 +0000https://chengyu.eu/posts/forcing-https-typecho-tencent-lighthouse/The blog answered on both HTTP and HTTPS at once — tracking down the default_server catching every HTTP request and rewriting it into a clean 301 chain to a single canonical domain.https://chengyu.eu/posts/clawdbot-2026-vps-deployment/Wed, 28 Jan 2026 21:59:54 +0000https://chengyu.eu/posts/clawdbot-2026-vps-deployment/Working around a broken systemd installer, teaching a model to fetch stock data itself when the plugin store isn’t reachable, and locking the firewall down to SSH-only.https://chengyu.eu/posts/todays-ops-log-codex-network-podsync/Fri, 23 Jan 2026 15:00:18 +0000https://chengyu.eu/posts/todays-ops-log-codex-network-podsync/Moving from Cursor to OpenAI Codex, two days spent simplifying the network layout, a fix for Podsync’s YouTube rate-limiting, and a disposable-container trick for benchmarking a NAS.https://chengyu.eu/posts/caddy-reverse-proxy-freepbx/Wed, 21 Jan 2026 23:00:24 +0000https://chengyu.eu/posts/caddy-reverse-proxy-freepbx/FreePBX kept redirecting the browser back to its raw :8080 port even behind a reverse proxy — the fix was rewriting the Location header on the way out, not just spoofing headers going in.https://chengyu.eu/posts/switching-blog-to-acme-certificate/Wed, 21 Jan 2026 17:00:07 +0000https://chengyu.eu/posts/switching-blog-to-acme-certificate/Tired of Tencent Cloud’s free certificate silently expiring and needing manual re-binding, I moved my Typecho blog over to acme.sh via a Gitee mirror instead.https://chengyu.eu/posts/freepbx-diary-3-first-test-call/Mon, 19 Jan 2026 00:01:07 +0000https://chengyu.eu/posts/freepbx-diary-3-first-test-call/Creating extensions, getting UDP registration working first, then chasing down a misleading ‘wrong password’ error that was actually a TLS transport and certificate mismatch.https://chengyu.eu/posts/freepbx-diary-2-https-backup/Sun, 18 Jan 2026 20:00:47 +0000https://chengyu.eu/posts/freepbx-diary-2-https-backup/Getting Let’s Encrypt working on the admin panel and setting up a weekly automatic backup — the two unglamorous steps that make a

with FreePBX 17 on Debian — a Vultr trial instance, the official one-shot install script, and the firewall gotcha that can lock you out of your own server.https://chengyu.eu/posts/podsync-directory-exposure-fix/Wed, 09 Jul 2025 11:00:06 +0000https://chengyu.eu/posts/podsync-directory-exposure-fix/A missing index.html meant Podsync’s web server was serving up a full directory listing of everything it had synced — here’s the one-file fix.https://chengyu.eu/posts/minio-object-storage-project/Mon, 16 Jun 2025 09:00:05 +0000https://chengyu.eu/posts/minio-object-storage-project/Turning a cheap, low-spec server into a dedicated S3-compatible object store for images, audio, and video, instead of hosting another website on it.https://chengyu.eu/posts/gl-sft1200-router-reflash/Wed, 11 Jun 2025 11:00:16 +0000https://chengyu.eu/posts/gl-sft1200-router-reflash/A painfully slow GL.iNet Opal, rescued from a drawer with a
