Interesting. Why do you think the digitalisation is the root cause of this?
What I mean is, if the intent was to provide a cheaper service, why digitalise it in the first place (in this example, why provide APIs 15 years ago, and then slowly lock everything down?)? The bus routes themselves aren’t more or less expensive to run because of the information sharing, are they?

I doubt the digitalisation has anything to do with it. It’s companies pursuing unrealistic profits and forgetting that putting the customer front and center is what makes “good service”.
I used to be able to see where a bus was, within meters, about 15 years ago. Now it’s impressive when the display at the bus stop is actually synchronised with reality at all.
Sorry Mat for your terrible evening. Must have been incredibly frustrating and stressful

I think the “dang” comment is actually crediting you as the source material.

Just to clarify, you’re saying it like it’s a bad thing?

Putain la toxicité quand même. Zéro place au doute ou à l’innocence. Juste des insultes instantanées, une vilification sans limite simplement parce que tu as rt un truc.
Ils auraient pu te contacter, en public ou en DM, pour t’informer du comportement du groupe concerné. Mais non, un fil en // sans te ping. C’est dingue comme attitude quand même.

Near Malmö? I might be thinking about selling my MK4S, with enclosure, and I could drop it off (I’m based in Copenhagen).

600 USD is closer to 500 EUR in pure value, and with taxes and tariffs that can shift the balance even further. Where are you based, generally speaking?

Depends what kind of chemistry. There’s all the pharma companies, yeast, etc.

I’d be genuinely interested in knowing how long the 3DP part last compared to the metal one. I’m guessing it’s not the weak spring that generated the metal fatigue, but the repeated solenoid impacts?

Nice! What language did you use? Mine took about 150us for both (although my benchmark re-parses the input for each step).

Sure, but I doubt someone who listens to the curious or opinion hashtags (only) would have more to contribute than someone who follows the neovim hashtag.

Haven’t heard of fennel, I’ll look into it.
I do think you need to calm down with the hashtags though. Only 3-5 were relevant.

@npub1p09…m5vl Did you see this? Thoughts?

I saw the calls from previous #ESC winners to the EBU to drop Israel this year.
And every time the Maroccanoil logo is visible you know why they wouldn’t even consider it for a second.

Interesting, Prusa announces that the MMU3 won’t be upgradeable to the MMU4–or whatever it will be called. I wonder how much backlash they’ll get over that.
And the stacked-on-top MMU3 for the CoreOne is just a “community build”. Interesting, interesting. Not sure why it’s not a viable product.

For the past few decades, when I travelled to the US, I have been using a burner phone that does not contain any data. I wait until I’m across the border, and only then restore the phone from a backup.
I’ve been called crazy and paranoid. I feel vindicated as I see the amount of people being detained over what their private conversations contained.
These powers are not new. This overreach is not a Trumpism. W started boiling the frog, Obama turned up the heat. Trump is using a microwave.

I’m waiting for the kit to be available and tested before ordering. My MK4S is still good, but I’d love to regain some real estate on my workbench.
I’m also hoping Prusa will either come out with a second tool head or a design to have the entire MMU3 on top of the CoreOne.

There’s no app for Vernissage (on iOS at least). I just use the PWA version, which works well enough.

In that video the person quotes “Prusa acted in response to a 3rd party report”. Sounds to me like NTI’s lawyers was going through all the IP saw something not in compliance, submitted a report, and when NTI saw the negative backlash, they tried to wash their hands clean.
Also, I don’t know how much weight to put in that video’s research considering they claim NTI is Swedish when in reality it’s Danish.

The biggest tip: make individual errors for every single fallible operation. Don’t try to make one giant error type for all things in your code.

Seems like you’re describing the Prusa XL (large, multi material (including TPE), and available now).

Okay, I accept they were needed to get Teen to create the road. But beyond that? They were unnecessary on the road. With the non-witch dying, Rio could have found their location without being summoned. Agatha despatching the sisters after only sipping from Teen’s power, but then being outgunned by Rio would’ve said more about the power dynamics than what we got.
Anyway, I’m not expecting to convince you. I’m glad you enjoyed it, and I will be watching S2 if it ever comes.

I fully agree that I enjoyed some aspects of the story. The non-linear experience was fun. But, the Salem sisters were pointless, Agatha vs Rio was inconsistent (she’s clearly been fighting Rio for centuries, so why just give up now? Why not give up in the first episode?), we didn’t need two full episodes of trials, there was no emotional investment when people died, Agatha had clearly never been on the road herself. As I said, trimmed, this show could have been solid.

Agatha All Along is the perfect example of a show that, while already not fantastic to begin with, is completely ruined by its last episode. The final episode brings basically nothing, except that it spoon feeds everything to the audience.
Cut 2-3 episodes, and the show could be an interesting 6.5/10. Remove the final episode, and it could be a 5.5/10. With the final episode included, 3.5/10.

How is the gridfinity stuff working out with 0.6mm? I thought from Zac’s description it was designed for 0.4, but maybe I misread?
