  • I consider code and data to be mangled within the context of a macro.

    In the macro definition we receive the code as data even though it looks like code when using the macro. Being able to use any lisp code inside of the macro definition, including other macros, makes for a mentally cohesive programming environment.

    Not sure I ever used eval aside from some genetic programming experiments.






  • First off, it looks good as it is. Well done! Also, it works and that’s the important bit. Some things which help me:

    • use equality constraints instead of repeating measurements for radii and lengths
    • fillets can be added after creating the main shape, this simplifies the sketch
    • if you know this will be mirrored, draw a quarter and mirror the extruded body in part design (you could use multi-transform here)
    • use formulas, spreadsheets or reuse named distances if you want to change things later
    • make extensive use of the Part Design workbench but sometimes dabble in another workbench because when they click you’ll unlock a new set of combinations and turn FreeCAD into a sort of swiss army knife

    Congrats on your first model 👏






  • There is a standard connector which existed before big screens landed in cars, the OBD2 connector. Dongles are cheap and you can read the output from your phone or computer. Some dongles support bluetooth. The connector is mandated in some markets and I guess that makes it less interesting to add a redundant interface inside of the car. It’s fun to try if you’re interested. Manufacturers can extend the error codes IIRC.

    Tesla has a service mode on the display through which you can scan the car for faults, run a battery test, … It is password protected but the password is publicly available.




  • I agree, elections should be held fairly or should be held again. I’m not sure what to say to naysayers claiming the establishment controls the results. I also wonder how we can ensure this doesn’t get misused.

    It would be great to have broad discussions around the topic and apply these measures when things get out of hand.

    I think we must stop personalised automated (selection of) content towards end-users for anything that might be political (and possibly just anything). There could be a place for such systems if the biases and tracking can easily be controlled by end-users such that they could easily apply other points of view.




  • I run e/OS on a FP5. I ran e/OS on a Essential PH-1 before and going back to a phone with Google installed just didn’t sit right with me. I did not feel like I could trust the device even after trying to toggle as much of the creepy spying off. As if there’s still someone probably looking over your shoulder because you configured something wrong.

    It is not perfect, but it is easy to use and full-featured. All regular apps feel great and battery life is good. I still use specific Google services (such as the calendar for work) but no specific Google apps. I guess Maps is the biggest challenge now but alternatives are good enough to get around with.

    You can run Android apps. Not sure about payed Android apps. I try to install FOSS apps through the integrated f-droid store if they’re available there. Installing app store apps sometimes fails because Google blocked the installer. I could install everything so far when needed (including banking apps and specific apps for the vacuum cleaner and such). Sometimes the Android app store apps don’t update for a while and I don’t notice.

    I don’t use Murena’s services but self-host Nextcloud. Based on the information they send I think they’re doing a great job for their size.

    I flashed the FP5 myself with a beta of e/OS when it was just out because the other phone was broken and (again) I did not feel right with the spying demon in my pocket with native Android. You could flash your device too.

    It’s comfortable on this side. If you have further specific questions, shoot.
