    At this weekend I finally established another network in my home — a ZigBee network. A looong time ago (in 2010 year) I touched the ZigBee networking in my university (ITMO, previously IFMO, in Saint-Petersburg) — these times it was a new technology, not used widely. And as a student I have some fun time playing with ZigBee main router, supplemental router and end-devices. You can view old photos and screenshots of old software on a my extremely old blog: http://h0rr0rr-drag0n.blogspot.com/2010/04/cc2530zdk.html (and read a blogpost, if you understand Russian).It is kindly fascinating, that now, after 15 years, I can just buy some ZigBee-powered devices from AliExpress (using Black Friday discounts) and connect them to the network inside my house right in the way I did it in the university 15 years ago!Sadly, although I bought native supported main router device, based on the EFR32MG2 with some software from Ember (EZSP v8) inside, the OpenHAB doesn't support this device natively — it supports it, but since my server is running NetBSD, I got problems with some bundled with OpenHAB things. Looks like some native libraries (rxtx-java) don't have bundled NetBSD versions. And the same library in the repository built for Java 8, not for Java 17.So, I decided to use Zigbee2MQTT, not to build the necessary Java library myself. It was kinda scary — use program, which connects my ZigBee network via ZigBee USB-dongle to the MQTT server — which is written on JavaScript . Not on the C (as I can totally understand, for a such low-level program, operating with embedded devices) or at least on the C++/Perl/Python/whatever. But, looks like it works good enough, if I don't try to pair the device in wrong mode (my window sensors has two modes to pair them with network: first "common" mode causes zigbee2mqtt to silently crash and the second "compatible" mode works without problems).And I could understand now, why people has so much problems with smart home security. Installed MQTT server mosquitto — it allows unauthenticated connections by default. Installed zigbee2mqtt — it allow connections to frontend without any password by default At least these two services don't each much memory: 1.2 Mb for Mosquitto and 75.6 Mb for ZigBee2MQTT.For now, my ZigBee sensors works pretty well and robust, like these devices from university 15 years ago #HomeAutomation #OpenHAB #ZigBee #HomeLab

    Has #friendica stopped including the profile image/icon in the #activitypub actor feed?Pulled the recent stable image after a few months of things working, and it's gone.Have I missed a setting?#selfhosting #homelab

    PG&E outage for all of Sunnyvale, UPS resources kept the home office and homelab online most of the hours. In the interim via LTE, decided to resume efforts on spec'ing the latest network refresh.Big decisions; mostly around scale model design principles, some blandness re: OFED drivers and SPDK version parity for specific NIC/DPU SKUs, and analysis paralysis when focusing on critical nerdatorium protocol support.Otherwise to say... I'm leaning towards additional Bluefield DPUs, where offload options are more important than bandwidth parity for production port speeds (also lower total port count using 4x25 breakouts), and there's no sense in paying more per unit for a CX6 25G vs BF2 25G... so... yep.#networking #homelab #mellanox #nvidia #dpu #zfs #distributedsystems #ai #hpc

    @constancies @Larvitz Get a VPS (Virtual Private Server, around 5€/month). Install Linux on it. Get a domain. Be ready to invest some time. Feel free to read my series on the topic, starting at https://jan.wildeboer.net/2022/08/Email-0-The-Journey-2022/ Decide if you’re ready.
