They only made those changes after several of the people whose likeness they stole called them out. Regardless, it should never have happened in the first place.

You mean the browser that was caught injecting affiliate codes on cryptocurrency sites and misleading users into making donations that were collected by brave instead of the supposed recipient? That browser?
- Comment on AI slows down some experienced software developers, study finds 6 days ago:
This line of thought is short sighted. Your senior engineers will eventually retire or leave the company. If everyone replaces junior engineers with ai, then there will be nobody with the experience to fill those empty seats. Then you end up with no junior engineers and no senior engineers, so who is wrangling the ai?
- Comment on Anker's 3D texture printer raises $45 million in most successful Kickstarter campaign ever — world's first UV printer for personal use to begin shipping in August 2 weeks ago:
That’s cool as hell. My understanding is you have to have extremely high volume before uv makes financial sense. The previously-available commercial uv printers are extremely expensive, so the anker printer is only cheap by comparison. Hopefully we will see some more competition at this level that will continue to bring the price down towards something more affordable!

Yup, happens to me occasionally, typically on my morning commute when I’m still waking up. Scary as fuck every time.

UV printers are used for direct to object printing, you likely own some stuff that has gone through the process. It’s especially popular for customized promotional items that would be otherwise difficult to print on, like flash drives, gold balls, etc. Admittedly, I also don’t see much of a reason to buy this for my own use, but one could say the same about other hobbies like 3d printing.

Anecdotally, something like gum or jerky to chew on helps me stave off highway hypnosis on longer road trips. I also find stopping and getting out to walk around for a few minutes helps fight the worst of it.

- Comment on 3D Printer Simulator could take the guesswork out of printing — Virtual 3D printer mirrors physical machine's quirks, like stringing, supports multi-color printing 5 weeks ago:
The thing is, running a simulation is a pretty inefficient way to do this. Until relatively recently, most printers lacked the computational bandwidth to run a simulation in parallel with active control (my ender 3 back in 2018 didn’t even have the capacity to enable all features if you wanted a leveling probe). Even now, you wouldn’t want to run this on the same hardware that’s actually controlling the machine, since the simulation would delay its ability to send control signals in real time. That’s why Klipper uses a secondary control board, it offloads the extra computation to ensure the primary controller only has to compute the bare minimum to operate with as minimal a delay as possible.
Also, a parallel simulation just isn’t necessarily the most efficient way to catch issues. Thermal control accuracy has been a focus in the printing community at least since Anet A8 printers were burning down people’s homes, and we’re pretty good at preventing thermal runway these days.
On the motor side, the accuracy issues are largely a result of an open loop control system- The steppers have no way of telling the controller that they moved the correct amount. Thus, a simulation wouldn’t help with positional accuracy since the board has no idea if a motor misses a step anyway. There are some mitigating tools like stallguard for load sending, but it’s not really the same thing.

I think this will ultimately fall into the same category as watching a simukated CAM toolpath before running CNC machining operations- it will catch the more obvious mistakes like unsupported surfaces, but won’t be useful at catching more subtle issues caused by specific idiosyncrasies of the machine or material.

The Bambu printers do some cool stuff with measuring resonance to measure things like lubrication and belt tension. This is theoretically possible on any machine that can do Klipper’s inout shaping, but requires a LOT of data to be useful (from what I understand), which is orobably why we don’t see many printers on the market that can do that.
For thermals, Marlin (one of the popular printer firmwares) actually evaluates the control response of the heater based on the, rather than just looking at a specific temperature range. If the behavior is sufficiently different than what the system is tuned for, it will throw a temp error and shut down before thermal runaway occurs. I would expect other modern firmwares (e.g. Klipper) do this as well, but I don’t have as much experience tinkering with them and don’t want to make definitive statements.

Very early on, Tesla used lidar in addition to optical sensors. However, they only use optical sensors today and have for a while. Like many of the poor decisions at that company, the change to optical-only was made at Musk’s demand.

Thanks for clarifying, I thought the comment above was asking why it needed file access in the first place, not all file access.

How do you think torrents work? They basically just download a file, but from multiple people instead of a single server. It needs access to the file system so it can save the files.

Aw man, not that their machines were really anything special, but my printing journey started with their rebadged wanhao duplicator i3. Monoprice printers somehow made even creality look expensive at the time!
- Comment on Need help with 3d printer 2 months ago:
Looks like this printer is a rebadged flashforge adventurer. Monoprice also sells a version. You might be able to find a version of the firmware from one of those companies and use it.
