Man, that’s cool! Concrete is a heck of a lot cheaper than epoxy granite resin and is perfectly suitable for a low-precision tool like this lathe.

I do hope that he finds a way to shield those bearings. You really don’t want metal chips or sawdust making its way in there. Any damage they sustain will cause runout, which will lead to increased chatter and parts that are out of spec. Plus, a matching pair of tapered roller bearings can be quite expensive!

EDIT: to be clear, I mean no disrespect when I say low-precision. Not every lathe needs to have slides and handwheels. I have a little Sherline lathe that I’ve used like this in the past (using gravers, not tools in a tool holder). It’s great to quickly turn something or to put nice decorative details on a part. Precision is possible with a lathe like this, but it requires fairly strenuous effort.

Based off of your comment history, it seeeeems like you live in the US, although I could deffo be wrong. That’s where I live, so I may have good news. It’s illegal to sell tritium products in the US, but it’s not illegal to buy it as an individual. There’s a Taiwanese company that sells all kinds of cool little tritium widgets: https://www.mixglo.com/

that’s where I got my vial from. It wasn’t cheap for what it is, but I think it’s cool.

edit: looks like they also ship to Canada if you live there. I’ve no idea what the laws are up there, but I’m assuming it’s legal if they’re willing to ship.

God, what a wonderful thread that was. I’ve decided to follow and star @mizu@lemmy.world so I can follow up on their future exploits.

Sadly, it doesn’t appear that they’ve posted in quite some time. Hopefully they’ll come out of hiding one day and ask more ridiculous questions.

I have a little tritium vial on my keys because I am a clumsy oaf with ADHD and the little greeny glow has been useful a couple of times. It’s great when I’m out at night and my keys yeet themselves out of my pocket and land in the darkest possible area.

I mostly got it because it’s cool though. Radioluminescence is fukken rad!

I just have the 0.6mm nozzles mine came with. I recall hearing something like that, but I’ve felt that the phat 0.6 lads were good enough for the stuff I’m printing. If that’s a limitation, then I hope Prusa can fix it. Seems like it shouldn’t be a big deal to make that configurable.

I own a Prusa XL and I love it. it’s the most reliable printer I’ve ever owned by a long shot. The only thing I’ve been unhappy with is the somewhat lackluster support for Octoprint, but I’ve heard that others have been able to fully use the printer with the right configuration.

Right, but I can’t require a second factor on a different device that operates outside of my primary device’s trust store. I’m sure there is some way to make my desktop hit my phone up directly and ask for fingerprint auth before unlocking the local keystore, but that still depends on the security of my device and my trust store. I don’t want the second factor to be totally locked to the device I’m running on. I want the server to say, “oh, cool, here’s this passkey. It looks good, but we also need a TOTP from you before you can log in,” or “loving the passkey, but I also need you to respond to the push notification we just sent to a different device and prove your identity biometrically over there.” I don’t want my second factor to be on the same device as my primary factor. I don’t know why a passkey (potentially protected by local biometric auth) + a separate server-required second factor (TOTP or push notification to a different device or something) isn’t an option.

EDIT: I could make it so a fingerprint would decrypt my SSH key rather than what I have now (i.e. a password). That would effectively be the same number of factors as you’re describing for a passkey, and it would not be good enough for my organization’s security model, nor would it be good enough for me.

I just don’t get why I can’t use something like TOTP from my phone or a key fob when logging in with a passkey from my desktop. Why does my second factor have to be an on-device biometrically protected keystore? The sites I’m thinking of currently support TOTP when using passwords, so why can’t they support the same thing when using passkeys? I don’t want to place all my trust in the security of my keystore. I like that I have to unlock my phone to get a TOTP. Someone would have to compromise my local keystore and my phone, which makes it a better second factor in my opinion.

EDIT: like, at work, I ssh to servers all over the damn place using an ssh key. I have to get to those servers through a jump box that requires me to unlock my phone and provide a biometric second factor before it will allow me through. That’s asymmetric cryptography + a second factor of authentication that’s still effective even if someone has compromised my machine and has direct access to my private key. That’s what I want from passkeys.

This is a bad take. Several cities in my state banded together to create a municipal fiber network called UTOPIA. The fiber is owned by the cities that bought in and is used by several different ISPs. The ISPs pay UTOPIA for access, and then they have to compete with each other for subscribers based on performance, features, and cost. Like, there’s genuine market competition for internet! If the state owns the infrastructure and then forces the playing field to be level, then everyone benefits. People in the cities with UTOPIA got fast fiber internet waaay faster than anyone else, they have a plethora of choices (want a static IP and a business plan in your residence? There’s an ISP that sells that!) at great prices, ISPs get access to subscribers without having to maintain fiber, and the cities who bought in get to make money from this and attract residents and businesses who benefit from the service.

My city didn’t buy in. Google Fiber eventually came to town so I was able to kick Comcast out, but I am uneasy about what’ll happen if Google decides to drop their ISP business. If I was in a city with UTOPIA, it would just be one ISP folding and I’d be able to pick a new one and switch over right away.

EDIT: cool, Cory Doctorow wrote a blag post about it: https://doctorow.medium.com/https-pluralistic-net-2024-05-16-symmetrical-10gb-for-119-utopia-347e64869977
UTOPIA users have access to 18 different ISPs. I feel like that speaks for itself right there. This is the future we all should have had.

It already is. My company runs hundreds (possibly thousands) of ARM64-based instances right now. It’s done great things for our cloud spend. We still have more x86 stuff than ARM because some applications just don’t perform as well on ARM, but I can imagine that ratio will change as software gets more optimized (specifically the JDK, golang’s compiler, and GCC/LLVM) and Ampere releases new systems with better single thread perf.

EDIT: Ampere, not Alterra. God damn tech company names.

You can run Asahi Linux on M1 MacBooks right now. If you didn’t see the news, they’ve even been able to run some relatively modern AAA games with decent enough frame rates. Granted that’s only the M1 macs, but there’s at least one relatively modern ARM laptop that you can run Linux on.

I’ll totally concede that the new Snapdragon laptops aren’t running Linux yet. It seems like Qualcomm is taking Linux support seriously, but I’m a bit skeptical as someone who has been absolutely fucked by a shitty Qualcomm kernel module.

I just wish that companies enabling passkeys would still allow password+MFA. There are several sites that, when you enable passkeys, lock you out of MFA for devices that lack a biometric second factor of authentication. I’d love to use passkeys + biometrics otherwise, since I’ve often felt that the auth problem would be best solved with asymmetric cryptography.

EDIT: I meant to say “would still allow passkeys+MFA.” hooray for sleep deprivation lol.

This random git repo I picked from their source forge page seems to have some pretty recent commits. I’m guessing they just have a slow release cycle.

Starship landing was a success too! They landed right on target this time. There was still a bit of burn-through at one of the aft fins (much less than before), and it exploded a little bit after it landed. Hopefully they’ll be able to land Starship on the ground next!

Holy shit, really‽ I had no idea.

I fukken love fat boys. Sometimes I’ll mix up the name to introduce some fun to a situation. One time I turned to my partner and said “be right back I’m gonna absolutely fucking destroy a fat man” and she was deeply confused until I came back with an ice cream sandwich.

I think they’re all top-level responses too. I took a random sampling of their comments, and they never respond to anyone else’s comment. That smells like someone being lazy and not bothering to iterate through comments when writing their dumb AI commenting script.

Like, just, what the fuck is this shit? There’s one comment from 8 months ago that looks real. Everything else is from the past week and reads like LLM drivel. Why would you bother? Is it just someone who is bored and wanted to see how long they could convince people?

Thank god for projects like Valetudo thar let you break your stuff away from the cloud.

Semi-related story time. I bought a Midea Cube dehumidifier for my laundry room. My dryer has been broken for years, and I’ve found that air drying clothes makes them last a lot longer. It’s hard to air dry inside, hence the dehumidifier. My plan was to control the dehu automagically with Home Assistant along with some fans, so people could just click a button to turn all the shit on to dry their clothes.

After buying it, I realized that the dehumidifier could only be controlled via the cloud, and the cloud control was unreliable as fuck. With the exception of tech people, nobody is willing to deal with my flaky bullshit. If the button doesn’t work consistently, my partner, her other partner, and my FIL aren’t going to bother. Luckily, a very industrious person made this thing that let me rip out the hardware responsible for cloud connectivity and replace it with a cheap microcontroller. Now, my dehumidifier talks to my Home Assistant server directly via MQTT and it just fucking works.

Give me local-only control or fuck off, I’ll take control myself. It’s not much to demand, and shit like what this article describes absolutely deepens my conviction around local-only control.

I hate that it’s so hard to get these people to agree to capex. My current company runs a few datacenters, and we have some teams that use them for their base load. It saves a shitload of money! Like, I don’t get why this is a concept that MBAs reject. You don’t have to go all in on capex for your infrastructure, just find a nice mix of capex/opex. If you’re afraid that you won’t use the shit you bought later on, then you should probably make sure that the market is there for whatever you’re selling before you dive in headfirst.

I was looking for this comment so I can vent my extreme irritation to the world.

God, can this concept please die already‽ If you want to put solar panels where the cars/trains are, just 👏 fucking 👏 put 👏 them 👏 on 👏 top👏

Do not put them on the ground where they will get smushed and covered in dust and snow and dirt. do not. Just make a little roof for the train tracks/road/bike path/sidewalk/game trail/snail raceway and then put the panels on top of the roof and then if you’re feeling fancy angle the panels to point towards the sun and if you’re feeling really quite fancy then you can use bifacial panels to capture the backscatter from the ground and shit and then we can all be happy. solar ground no, solar roof yes, ground no roof yes. do not play the trolley problem with solar panels on the railroad tracks. we have been doing solar energy for decades and have fucking minmaxed this shit so why are they still trying to do this just STOP.

Fuck.

Person I’m responding to, please know that none of this is directed at you. I’m just sour right now and should get off the internet.
