I should try this on my XL. I have big dumb 0.6 nozzles right now so it’d look like garbo, but I could print it in PLA with PETG supports. Being able to have almost no space between the support and primary material would probably make many alternative orientations possible.

For those who don’t know (including me):

Shotcut is a free, open source, cross-platform video editor.

I could see the NT kernel being okay in isolation, but the rest of Windows coming along for the ride puts the kibosh on that idea.

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.

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 obviously wrong. The children yearn for the mines, not the slaughterhouse. They should be swinging a pickaxe at some pitchblende in an unventilated tunnel after school, not cutting up meat.

(/s obvs, I find the whole “the children yearn for the mines” thing to be just my kind of dark humor.)

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!

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 don’t want an AI shitting up my nice, clean, best-practice following bash.

EDIT: Sorry for this comment. I really need to deal with my anger towards AI. The sentiment expressed is what I think, but I’m not happy with the aggressive and dismissive way I communicated.

I liked how each of the sections ended with a different game that she’s gotten running so far. It makes the article feel like a progressively bigger flex, which, of course, it is. Awesome to see this work progressing!

Seriously. The ECU in my partner’s truck decided that it was done with magic smoke and Marie Kondo’d that shit out, leaving her stranded. Her truck is an old 2002 Dodge Dakota that we’ve been nursing along while the used car market cools down (we want to get her something small and fuel efficient, but cars cost too damn much). Back in 2000 or 2001, some bean counter at Dodge decided that the company really had to cheap the fuck out with their ECUs for the 2002 model year. Because of this, any 2002 Dodge truck has either had its ECU replaced or is a ticking fucking time bomb.

What’s even better is that nobody makes these shit-ass ECUs anymore. The only replacements you can get are remanufactured units, and it’s highly likely that you’ll get at least one dud before you can find anything decent. We’ve been a tiiiiiiny bit less lucky than that, meaning we’re on our 13th ECU. Our mechanic has gone through everything else to make sure there’s not something external that’s exploding the ECUs, and he hasn’t found anything. Over the course of like 9 weeks, we’ve completely deleted the stock of these stupid things in Utah and all of the surrounding states. We’re now ordering one from Florida that’s been remanufactured by a different company which hopefully won’t grenade itself.

Fuck American car companies, and apologies to anyone who’s currently having a hard time sourcing an ECU for a 2002 Dodge Dakota. We screened all the bad ones out for you. The only good part about all of this for us is that our mechanic isn’t charging us for anything more than one ECU replacement. The damn truck has been in the shop for 9 weeks, and we’re only going to pay like $1000.
