  • other techies I’ve worked with had humanities degrees

    My sister, who’s been an occupational therapist, personal assistant and on other ‘soft’ jobs recently got hired as a helpdesk employee just for that reason. Apparently it’s easier to teach a humanist to reset M365 passwords and do simple troubleshooting than teach a techie on how to deal with humans (which is a major part of being an on-call support for anything).



  • I actually did something for quite a while. Finished long overdue wiring for outdoor access point and one more camera, replaced a main switch since the old one started to behave unreliably, installed frigate (which still needs some work), cleaned up some wiring while messing around, updated a bunch of firmwares, replaced switch in garage to managed one and made some changes on my workstation and some other minor stuff.

    Next would be to move cameras into their own VLAN and harden that setup a bit. And I really should get around on better backups for my VPS. But it’s a new week coming up, if the work isn’t too busy I might get something more done.


  • When I watch Iron Man or Batman talking to a computer, I don’t see some pinnacle of efficiency, I see inefficiency.

    Things like Jarvis from Iron Man are far beyond of just translating speech to computer commands. Like in the first Iron Man where Jarvis pretty much manages the whole process on manufacturing the suit and can autonomically manage a fleet of them. I could see benefit if some kind of AI could just listen on a engineers discussion and update CAD models based on that, taking care of that the assemblies work as they should, keeping everything in spec and managing all the documents accordingly. But that’s pretty much human-level AI at that point and specially the current LLM hype is fundamentally very different from it.



  • Snap Controversy

    Just today at work other team wrote a bunch of ready-made images on their SBCs. In about 10% of them snap shat the bed by corrupting one json file which rendered their environment unusable. They did it in a pretty stupid way by writing an sd card, inserting it into SBC, booting up and disconnecting power after very short visual confirmation that system gave some signs of life. And snap was doing whatever it’s doing in the background. So I had the pleasure of removing said json-file and reinstalling all their crap manually on those failed units.

    So, maybe not strictly speaking fault of snapd, but yet another problem it caused for me without any practical reason other than the environment they chose just uses snap instead of something more robust.








  • I’m using Z-TRM3 by Heatit for a part of our floor heating. The controlling itself works just fine, but I’ve seen a bit of interference on z-wave network after installing that and also there’s an annoying feature that you can’t manually control the heater if you turn it off from z-wave (I want that my devices can function as dumb ones if needed). So, not an answer to your question, but based on that one single unit I wouldn’t recommend that, even if it’s decently priced and looks pretty good on paper.

    In here our doors open to outside, so you can’t kick them in and as weather goes below -30C in the winter they’re pretty sturdy for insulation. Also nearly every door has some kind of abloy-lock which is practically pick-proof and hinges have safety pins so you can’t pull the door out that way (again, that’s more to do with insulation and weight management than safety). And commonly right next to the door is a nice window to let daylight in.


  • DNS PTR records belong to the entity who owns the IP addresses, you can’t make reverse records for arbitary addresses like you can with forward zones. I haven’t heard about any residential ISP which would give access to PTR records and even on business lines that’s usually a premium.

    What you could do is to get a VPN service which gives you these options, if there is one, I don’t know. Most likely you’re looking for a VPS for that and tunnel traffic with some kind of VPN-setup to your local instance. And at that point you might as well run the whole thing on VPS unless you happen to need a ton of storage or some other reason makes pure VPS server too expensive.






  • It’s quite likely that any given IP, unless you get one from shady VPS provider or something, is “clean”. And if it’s not it’s usually not that big of a deal to get it cleared from major blacklists (spamhaus, google and microsoft covers quite a lot). You just need to dig up proper forms to tell them that you’re a new owner of said IP and promise to play nice.

    Same goes with domain names, but if you get a new one that’s a non-issue. Just set up SPF-records properly (and preferably DKIM/DMARC, but those aren’t strictly necessary and need a bit more than a single TXT-record) and you’re good to go.

    And then you of course need to stay away from those lists. If you configure your SMTP to act as a open proxy you’ll be on every shitlist on the planet pretty quickly. So, reasonable measures against compromised account (passwords, firewalls, rate limits…) and against other threats (misconfigured/unsafe web service used for spam and stuff like that). Any of those alone are not too difficult to accomplish, but there’s quite a few things you need to get right.
