  • Not who you responded to, but that’s an interesting source. I’m intrigued by a textile company claiming to be experts in lithium ion fires.

    It sounds more like options for preventing a fire to spread. It’s also including CO2 extinguishers under “foam” which they very much aren’t, making me doubt the rest of their blog post.

    Extinguishing fires can work largely in two different ways. Either by smothering a fire or by cooling a fuel below it’s flash point. Quite often they put out a fire by doing both. A fire that contains an oxidizer cannot be smothered, but smothering can help prevent other materials in a vehicle from being able to burn along with the batteries. Cooling down a large, vehicle sized lithium ion fires takes an incredible amount of water. However, the cells themselves contain so much energy that their failure produces more thermal energy than water is able to remove.

    Is water the best to put out large EV fires? Nope.

    Is water good at preventing fires from spreading? Yep.

    Is water easily accessible and carried on every fire truck and engine and available through hydrants? Also yep.

    A lot of agencies are including car sized fire blankets as well that help smother the fire some and make burnt/burning EVs safer for tow trucks to move to a safe locations where they can be left to burn out. Sometimes for over a month! You might see fire engines literally escorting tow trucks because even with the blanket and being doused with tens of thousands of gallons, it’s still at risk of reigniting during transport.

    The other big issue that agencies are facing with EV fires is that the water used to suppress these fires essentially becomes hazmat. So there are issues with letting it just run off into the storm system or the environment.







  • On her computer, why not just use Thunderbird on it? Or even outlook, or whatever she likes. She just needs to pick the software.

    On her phone, or even yours, why the stuff with accessing Thunderbird through vnc. Just add the server to whatever mail app on your phones?

    If you want a web based thing, roundcube or sogo. But Thunderbird is gonna suck the way you are trying to use it.


  • Stupid rspamd default config on my server blocked an email confirming an order from rayban I guess because it was the first time it saw an email from them? Couldn’t even release it, which annoyed me greatly.

    And it also put a confirmation from a hotel into quarantine because the resort didn’t have a valid spf record. But at least I could release that one.

    I ended up making it much more permissive as a result. But it was super annoying.



  • Honestly, I think our regulations have gone a little too far. Requiring backup cameras and automatic braking systems sounds like a good idea, but now we can’t have a bare bones car.

    Prices are up because there are so much additional shit they need to include. Personally, for a lot of my driving, all I want is a geo metro or similar shit box.

    I mean, if I buy a two-seater convertible (if I can even find a new one) why does it need a backup camera? There isn’t even a back window!
