    Hello, hachyderm.io! I'm Artur Manuel, better known as @amadaluzia across other platforms.I've been on Mastodon in the past under @amadaluzia@bsd.cafe, and recently moved in because I was self-consious about my status as a *BSD user. If you aren't sure who I am from that tag alone, I have a webpage that describes who I am that can be found in the following URL.https://amadaluzia.is-a.devYou should expect long posts from me, as I generally like to write long posts for the sake of detail. If you want short form posts, wait for a while until I have a reason to make a short post, which can be pretty hard to find. Otherwise, you'll at least have something to read. :DAside from the basic Mastodon tags, I'll add my interests as well. I hope we can get along!#introduction #mastodon #linux #cybersecurity #programming #tech #foss #privacy

    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

    When I select a VPS how do I know that my data on the server is safe and private? Is trust all I've got?#SelfHosting #VPS #Linux
