I run a Mastodon (mammut.gogreenit.net) and PeerTube (pt.gogreenit.net) instances for myself and friends.

I am interested in IT, Electronic Music, Winter Sports, Renewable Energy, Off-Grid living, Sustainability, The Right to Repair and Animal Rights

  • Absolutely. In a previous company, we migrated from on-site MS Exchange to Google Mail (ugh). Apart from it being a crap experience (it was a new service), and feeling like we were beta testers as things kept changing daily, so writing training material was a PITA, once there was an outage, and even though we had ~10K users on it, they basically said “get in line” when we were chasing for updates etc even though we were a paying customer!

    Fuck them.




  • No licence is required for this model. I wouldn’t give away something that needed a shitty licence without mentioning it (but then I probably wouldn’t have taken it for myself in the first place).

    I made that mistake with an Infobox device at an auction a few years ago. You can use all functionality for 30 days, then after that you need a licence or NOTHING works and you have to wipe it all and start again. What a pile of shit, I only wanted to play with it and run a few DNS zones.

    It’s a shame, I was hoping to learn something from it as they cost a fortune, and usually overkill for what I need, but instead i’m never going to recommend their products. I could open it up and see if I can run Linux on it, but I don’t need yet another device that runs bog-standard Linux - any boring hardware could be used for that purpose. 😞






  • APC do a really crappy small one for telecoms cabinets, but none for servers
    

    I wonder if the lower discharge current capability of LFP batteries is why? That’s the one thing I’ve read fairly consistently about them is that they can’t supply the same high current as lead acids but are otherwise superior in every way. Now that you mention it, the only place I’ve ever really seen LFP UPSs for servers is in the big, central UPSs where they can run batteries in series for a much higher voltage.

    I don’t think so. Cheaper batteries have that problem, but a decent brand does not. Check out this one: https://www.powertechsystems.eu/home/products/48v-lithium-ion-battery-pack/48v-105ah-5-38kwh-lithium-ion-battery-pack-powerbrick/ I bought one for my house, and have a 5KW inverter connected to it. Its specifications say that can do 120A drain continuously. I have used it to boil my 3KW kettle a few times in one day (but not often - I usually use the power for other things), and it has been fine.

    e.g. most of the LFP UPSs I see max out at 1000 VA where 1500 is more typical for lead-acid UPSs.

    That’s just a limitation of the product, not the technology.






  • I’m not sure what you mean about “alternative process” for updates. In the chart you posted, the US got 466227 updates in 1 day which is about 14 million per month if that happens every day. If they are 100 bytes each (no idea if that is realistic), that’s 1.4GB a month for the whole US. Right now a new map download is something like 1.1GB for California alone. California is the biggest US state (not in terms of land area but certainly in terms of roads) but the whole US might be 10x or 20x bigger.

    Sorry, I’m not sure what you mean by that.

    I’d say OM is less in need of new features than of getting its existing features working solidly, warts ironed out, etc. The one major feature improvement i could see is getting the voice directions to include street names, but in practice it’s not that important, at least in my usage.

    Fair enough

    Google Maps has a sometimes useful feature that an offline app like OM can’t possibly get, which is routing and ETA calculations based on realtime road and traffic conditions. I don’t rely on that very often, but on occasion, it really helps. Unfortunately I suspect that much of the traffic data comes from the devices themselves phoning home with their locations, and only Google and Apple have enough devices out there to usefully do that.

    Yes, that’s exactly how it works. I get tracked enough without adding my location data, so however useful it is, I can live without it.



  • I don’t mean OM gives me a choice of routes. Rather, say there are two reasonable ways to reach the destination. OM chooses route A, says turn right, ok fine, I turn right. Then after a few seconds, OM changes its mind and wants route B instead. So it says take a U turn and go this other way, oops! But if you do that, it changes its mind AGAIN, and you end up going in circles.

    Weird, i’ve never had that happen to me!

    Re downloading a subset of the maps: yes I can do that, but then I have to predict which ones I’ll need, just another thing to remember. I have all the California maps installed so that if I suddenly decide to drive to Barstow or something, I don’t have to

    Ok, but what’ the alternative process?

    figure out which counties I’ll traverse, since they are all already downloaded. What I really want is to download ALL the maps, the whole world, might be 50GB or whatever, but that’s ok, we can buy 2TB microSD cards now. If that download was a one-time event with occasional small updates I could deal with it, but I don’t want to do the whole thing every cycle.

    Sure, it’s not as efficient as it could be, but maybe that will change with time. They are pretty good at adding features to it fairly regularly.
