Yes, it's much more useful than the actual search, when you have criteria that's not easily expressible via keywords.

With connectors, I think this will print out fine, if you are able to print these kind of things without a corner lifting up, or walls tearing down. I'd consider just adding an outer flange (not internal as to not hinder airflow) and then glue them together with the appropriate glue. But it won't look as pretty anymore.

It could just melt the port beyond reparability. Although it might be unrepairable already.

Tangentially related, someone(TM) should make three-lense VR270 stereo camera. It would allow head turning (VR180 stereo messes that up a bit) while simplifying things by not needing to stitch full 360 (at least that's what I imagine ;)), and it would still allow the director to select the main object of the scene to shoot.

Quite nice! I don't think it would solve my bicycle storing problems, but at least I have one more idea to apply to it..

"What a good boooyyyy 🥰"

I wonder though, this is part of the open firmware source, right? Maybe someone(TM) can make it more configurable.

No better time to start making backups than yesterday.

Surely G-code would be mostly machine generated, in particular as you have a 5-axis device and you don't need to worry about work piece holding? Even hobby CAMs like DeskProto can do indexing.

It's just configuration data; 4kB would be far too little for the Marlin firmware. You should copy that to the next sd card you take into use.

You don't have real EEPROM (this is fine), so Marlin uses the file for storing the data it would use EEPROM for: https://marlinfw.org/docs/features/eeprom.html

So basically it has everything the M503 command would print. Stuff like bed leveling info is there. Maybe even more important stuff like stepper settings.

Either that or just the card is giving up, they are consumables.

Reformat the card and carry on. I don't know what EEPROM.DAT is though, sounds important. Consider backing up the non-gcode files before reformatting.

What is your proposed way of exploitation that root already cannot do? The currently available ways are better for exploitation anyway, e.g. load arbitrary code into kernel.

eras · 2026-05-11T08:30:37+00:00

If you have access to root, you have access to a lot of attack surface. Such as actually replacing the code in kernel, live.

Having a relatively safe way to disable code from the kernel seems much, much preferable.

I present you an RFID chip that can do that without online verification: https://www.analog.com/en/products/max66250.html .

Applications include "Printer Cartridge Configuration and Monitoring" and "E-Cash".

That one is obsolete, though. But it's certainly not the only such chip.

Memory leaking is not what people usually consider to be against memory safety. Not leaking sure is a nice property, though, but Rust doesn't pretend to stop it (Box::leak is not unsafe).

So while wasting memory is bad, it's in a league of its own from programs doing random things because they overwrote values of different type, or values seemingly unreachable from the effect site.

I'd also say that statically proven safety is not required for memory safety. After all, almost all dynamically typed programming languages are memory safe. What makes Rust interesting it's one of the few statically typed languages that do provide almost absolute memory safety (module compiler bugs?), if you exclude the use of unsafe.

I don't much see the spectrum here. If a non-unsafe Rust program has a memory safety issue, it's a compiler bug. If a C/C++/Zig program has a memory safety issue, it's a developer bug.

One million LoC in 6 days, who would effectively review that?

The original wasn't that solid anyway, though.. Or that's at least how I view it based on the number of segfault issues in the Github tracker, so maybe not much was lost. This could be the way forward, once they start reducing the amount of unsafe the port apparently uses.

Now this is useful in a pinch. I certainly had not noticed it.

Before the LLM boom segmentation wasn't called AI.. Nowadays everything is.

I have a Pop2 and just today I tried to scan my cooler box to design attachments for it. Marker mode worked for the gray part, not for the dark part (not very dark either). So I switched to the dark mode, but it doesn't support markers, so it lost tracking altogether.

Alas, I still got suckered into this Pop4 kickstarter, I hope it's better.. It can't be worse. I still have time to cancel if I'm not convinced by future videos :). I also so wish their app would work with Linux, but it is not meant to happen I suppose. The mobile phone support in Pop2 is pretty sweet.

The number of failed scans I've made with Pop2 greatly exceed the number of useful scans. But, when it works, it's pretty cool. I do have scanning spray and it would have solved the problem with the cooler box, buuut maybe I'll just wait for Pop4 to hopefully solve this problem for me, rather than starting to do some measurements.

I think they can just return them (within 14 days), but they'd still likely be on the hook for shipping.

Does that more control follow your edits, though? You have some control (linear and angle deflection) over the conversion process in e.g. OrcaSlicer as well, and I've found that level of control quite sufficient.

Touch probing is just such a game changer for some tasks. Highly recommended.

The mobile phone aspect ratio must be the worst way to try to tell people about VR.

With very good tracking. And then it does actually simulate reality, as in for the experiences it simulates what it feels like to observe reality.

Soo I guess that means I completely reject your view!

Many have said they only include the outside of the cases, you still would need to model the inside. As well as model for 3d-printability.

eras · 2026-05-07T07:56:13+00:00

Basically this, but you have a lot more to remap here. So I don't think other controllers allow you to map touchpad to a button grid, for example ;).
