  • Cars are like horses: people will soon realise EVs are just better, claims VW boss

    Jump

  • Have a 2011 Lexus ES350 (gas, V6), and a 2013 Nissan Leaf (EV, ~60 miles of range). Both my wife and I prefer driving the Leaf around town because it's just plain fun. We keep the Lexus for long trips, but could honestly get by with a rental if we ever needed to.

  • Cars are trying to spy on you, and it's only just the beginning

    Jump

  • 2013 Nissan Leaf tries to, but it's online system died in the mid teens when they pulled the plug, and 2G is mostly phased out anyway. You can hack it to use a custom self hosted replacement server and an IoT SIM card tho!

  • Is it just me, or does this site lag like crazy, at least on mobile?

  • Delete LinkedIn – you'll have zero fucking regrets

    Jump

  • I keep it because it can be a useful way to get in touch with people I would only know professionally. For example, I used it to reach out to employees of a company I was applying to that used to work for the company I was trying to leave, to get a more honest opinion of the place. Past that though, I never even look at it, and I do actually try to keep my connections limited to people I know.

  • 'Windmill': China tests world’s first megawatt-level airship to capture high winds

  • Thanks for the correction! I got way ahead of myself.

  • When wind speed doubles, the energy it carries increases eightfold,

    Edit: I'm wrong, see edit below!

    Huh? Kinetic energy increase is square, not cubic.

    KE=1/2 m v^2

    So every doubling of speed should increase the available kinetic energy by 4 times, not 8. 3 times the speed is 9 times the energy. Granted there are probably some efficiency gains in excess of this at the low end, but as a rule that's just wrong.

    Edit: Cool, I learned something new! I neglected to consider it in terms of power, just thought about kinetic energy.

    So something like: KE = 1/2 m v^2

    = 1/2 ( rho V) v^2

    = 1/2 ( rho A d) (d/t)^2

    = 1/2 rho A d3 1/t2

    Where P = KE/t

    Thus:

    P = 1/2 rho A (d/t)^3

    = 1/2 rho A v^3

    Lots of other aspects I'm sure I have wrong, but I see how the cubic came to be.

  • A noob question about VPSs and bandwidth

    Jump

  • will all my Jellyfin traffic go through the VPS

    Yes

    and count as bandwidth used?

    Yes, twice (download from home to the server, and upload from the server to the client)

    I do the same thing - I have a 3TB limit, but usually only use 300GB, sharing Jellyfin to a dozen or so users.

    Edit: I'm sure there are plenty of good VPS providers out there, I personally have been using NerdRack for a few years now (got a VPS on special and the rate is locked as long as I keep it). Looks like they'll do $11/year right now for a KVM VPS that's sufficient.

  • Gillibrand Announces Legislation To Ban Distribution Of Blueprints For 3D Printed Firearms And Curb Epidemic Of “Ghost Guns” - Kirsten Gillibrand | U.S. Senator for New York

    Jump

  • Huh? This is from July 2023. There have been many of these proposed before, and possibly a few since. Looks like you need a license to distribute files these days anyway.

    I spent a few years designing 3D printed guns for fun, none of them were effective or well known, and I never manufactured any myself. I did that that as a teenager, before there were laws, and it's what got me into engineering before I pursued a degree. This was pretty early on in hobbyist 3D printing, it was all super experimental. Ultimately, 3D printing is just one method of manufacturing - there are many out there, and honestly the barrier of entry is low regardless of what method you choose. If someone has the skills to run a 3D printer, they can buy the hardware store components to make a gun regardless.

    The better bet for legislation would be to more comprehensively ban unlicensed manufacturing, whatever the method, and more strictly regulate which parts may be bought unlicensed (barrels, trigger assembly, magazine, etc). On a personal note, I think it's too deeply engrained in American culture to shift anyway, but I hope we keep trying to change the world for the better l (stricter background checks, more stringent home safety requirements, etc.)

  • We are way overdue for an open source 2d printer

    Jump

  • Ostensibly, that's because the app wants Bluetooth and/or WiFi access so it can connect to the printer. Because you can use WiFi and Bluetooth to determine location (based on large crowd sourced databases of these data points that have been geolocated), the OS has to ask for location permission as well, even if you just need to see WiFi and Bluetooth.

    That being said, once they have this permission, I have 0 doubt they log the actual location as well...

    Mozilla used to run a free service for this, and collected that data in the background using mobile Firefox. A replacement is https://beacondb.net/, which is still building enough location data to become useful. Services like this aren't nefarious, they're actually really important in getting a quick GPS lock on mobile. Phone hardware actually have pretty poor GPS receivers, but if you can determine an approximate location prior, you get much better results, especially once supplemented with inertial measurements and snapping to mapped roads.

  • Avoiding AI is hard – but our freedom to opt out must be protected

    Jump

  • Without reading the article, my first take is that no, it should be our right to opt-in. That is, it should be the default to be opted out, and only explicit permission ever opts you in.

  • I use Zip Bombs to Protect my Server

    Jump

  • I've found great success using a hardened ssh config with a limited set of supported Cyphers/MACs/KexAlgorithms. Nothing ever gets far enough to even trigger fail2ban. Then of course it's key only login from there.

  • Fully self-hosted password manager options

    Jump

  • Agree with others, Vaultwarden is probably your best bet. I've found the default app to be a little flaky, but ended up using Keyguard, which I've found really good.

    I used to use Keypass+Syncthing, but found sync conflicts too often (due to Syncthing support for Android), hence the switch.

  • Server upgrade/replacement help

    Jump

  • Anything USB connected more likely to be flaky, but a good enterprise disk shelf and a HBA card would be rock solid (just noisy...)

    Unfortunately my solution when I did a big data migration was to buy more (cheap) storage lol. Ultimately it was a cost vs. time/stress tradeoff.

  • Server upgrade/replacement help

    Jump

  • Physical space is actually a huge issue

    Ah then I'd recommend keep the existing machine as the server (it sounds like it's serving you well hardware wise), and get a SFF machine for regular desktop use, be that a new build or a used office machine. The trick will be in migrating the server to Linux, and without endangering your data in the process.
