I don’t know exactly, but it’s apparently a thing. Some game anti-cheat software such as Easy Anti-Cheat will give you an error message saying something along the lines of “Virtual machines are not supported.” Some are easy to bypass by just tweaking your VM config, others not so much.
Fair enough! I think it’s more common for games to do that, but sometimes I had trouble with software on Windows that used virtualization elements themself. I probably just didn’t properly configure HyperV settings, but I know nested virtualization can be tricky.
For me it’s also because I’m on a laptop, and my Windows VM relies on me passing through an external GPU over TB3 but my laptops’ dedicated GPU has no connection to a display, so it would be tricky to try and do GPU passthrough on the VM if I were on the go. I like being able to boot Windows on the go to edit photos in Lightroom, for example, but otherwise I’d prefer to run the Linux host and use the Windows VM only as needed.
I’m a fan of dual booting AND using a passthrough VM. It’s easiest to set up if your machine has two NVMe slots and you put each OS on its own drive. This way you can pass the Windows NVMe through to the VM directly.
The advantage of this configuration is that you get the convenience of not needing to reboot to run some Windows specific software, but if you need to run software that doesn’t play nice with virtualization (maybe a program has too large a performance hit with virtualization, or software you want to run doesn’t support virtualized systems, like some anticheat-enabled games), you can always reboot to your same Windows installation directly.
One of the big changes in my opinion is the addition of a “Smart Dimension” tool where the system interprets and previews the constraint that you want to apply instead of requiring you to pick the specific constraint ahead of time(almost identical to SOLIDWORKS), and the ability to add constraints such as length while drawing out shapes (like Autodesk Inventor, probably also Fusion but I haven’t used that). It makes the sketcher workflow more like other CAD programs and requires a little less manual work with constraints.
Hmm, that actually sounds like a bug. I haven’t seen that on my end (once I set the locations of options in my toolbars they stay there, even after restarts). You may want to report that on their issue tracker. Sorry that you’re having a rough experience!
Last I tried it, there was no fix. Their latest update on the website says:
The work on the toponaming problem is an ongoing project, and we are very grateful to the FreeCAD community for contributing a lot to that effort. But it’s not complete yet, there will be much more to say when it’s largely done. So let’s focus on the other three.
So I take it they haven’t implemented a fix. They previously said they were going to work with the FreeCAD team on mainlining a toponaming fix, using realthunder’s work as a proof of concept, but said fix has not landed in mainline FreeCAD yet. I believe that’s the major feature they’re looking to implement for FreeCAD 1.0.
Definitely excited for Ondsel though! Hopefully that fix can be integrated quickly.
IMO the bigger problem with FreeCAD is the topological naming problem. It’s very easy to get frustrated because your model broke due to a change you made in an earlier feature.
The UI isn’t amazing though, and that unfortunately happens quite a bit with open source software. Hopefully it’ll go the way of Blender and KiCAD with an eventual major release that overhauls the UI.
Ondel has a nicer user interface, but I personally use and recommend realthunder’s LinkStable branch of FreeCAD. Mainline FreeCAD (and by extension, Ondsel) suffer from the topological naming problem, which can be especially jarring to users coming from proprietary CAD software. realthunder put a lot of work into a solution that handles the problem pretty well, so I’m using his fork until toponaming gets mainlined.
Yep, and for good reason honestly. I work in CV and while I don’t work on autonomous vehicles, many of the folks I know have previously worked at companies or research institutes on these kinds of problems and all of them agree that in a scenario like this, you should treat the state of the vehicle as compromised and go into an error/shutdown mode.
Nobody wants to give their vehicle an override that can potentially harm the safety of those inside it or around it, and practically speaking there aren’t many options that guarantee safety other than this.
Afaik the StarFive SOCs used in SBCs are a lot slower than current ARM offerings. Part of that might be because software support is worse, so maybe compilers and related tooling aren’t yet optimized for them?
Hopefully development on these continues to improve though. The biggest nail in the coffin for Pi alternatives has been software support.
I haven’t used all of the assembly workbenches but I’ve found Assembly3 to be pretty robust to design changes if you use realthunder’s Link Stable fork of FreeCAD. I wouldn’t be surprised if all of the assembly workbenches would benefit from toponaming fixes, though I don’t know how they all work.
The topological naming problem is handled quite well by realthunder’s FreeCAD Link Branch fork, and his Assembly3 workbench is an acceptable, albeit imperfect method of making assemblies when combined with his fork. Assembly3 can run on upstream FreeCAD but I found it to work way less consistently due to issues like the topological naming problem breaking links in the assemblies.
Nonetheless the added features by Ondsel look interesting. I’d consider switching once upstream FreeCAD implements a solution to the topological naming problem, but like you mentioned, toponaming is such a huge leap in usefulness that I’m hesitant to switch to another FreeCAD version that doesn’t handle it well.
Not sure what’s going on but if the printer was flashed with Klipper, it won’t show anything on the screen until it is connected to a computer running klipper’s host software.
That sounds about right. You can technically achieve full torque at 0 RPM, but the current required for that might be very high (and may not be practical for the small size, power limits, and cost of a 3D printer). I know this is a problem in Asian import mini-lathes - if you run the spindle too slow you won’t get much torque out because the driver can’t supply enough current.
I think it would be a better idea to use linear encoders if you were going to add encoders to the shaft, as that way you could directly readout the position of the tool along an axis without issues like backlash that would mess up your calculated position. This is what I’ve seen on (both manual and CNC) mills and lathes.
BLDC and AC servos maintain full torque at stop too, and have about 2-3× the torque of a stepper of similar size.
Huh, this is true about BLDCs as well? I remember seeing in a video that BLDCs tend to have very poor torque output when stopped and especially when at low speeds (due to very low efficiency requiring too high currents for drivers to supply), whereas AC motors have a pretty much flat torque curve until they get fairly fast. I’d be interested to know if this is true.
I’m a researcher in ML and that’s not the definition that I’ve heard. Normally the way I’ve seen AI defined is any computational method with the ability to complete tasks that are thought to require intelligence.
This definition admittedly sucks. It’s very vague, and it comes with the problem that the bar for requiring intelligence shifts every time the field solves something new. We sort of go “well, given these relatively simple methods could solve it, I guess it couldn’t have really required intelligence.”
The definition you listed is generally more in line with AGI, which is what people likely think of when they hear the term AI.
I believe this is the referenced article:
I think what they mean is that ML models generally don’t directly store their training data, but that they instead use it to form a compressed latent space. Some elements of the training data may be perfectly recoverable from the latent space, but most won’t be. It’s not very surprising as a result that you can get it to reproduce copyrighted material word for word.
Yeah there’s a good chance you’re right. Maybe something to do with memory management as well.
Long term I’ll probably end up switching back to Darktable. I used it before and honestly it is quite good, but I currently have a free license for CC from my university and the AI denoise features in LR are pretty nice compared to the classical profiled denoise from Darktable. It does also help that the drivers for my SD card reader are less finicky on Windows so it’s easier for me to quickly copy over images from my camera on there instead of Linux. Hopefully that also gets better over time!
