Retraction Test
  • Wasn't aware of the test (SuperSlicer user here), and found this.

    The tower has multiple notches, each one corresponding to a different retraction length. By looking at the tower after printing, you can see how each retraction length affects the print quality.

    So check your surface finish and select the retraction value with the best looks.

  • Looking for recommendations for homebrew security system cameras
  • Esp32Cam with esphome running a webserver, add frigate in the mix and you can have dozens of cameras for just a few bucks.

    Completely open source (apart from the espressif wifi radio stack, but who's counting) and low cost.

    Yes, quality of the camera will never compete with commercial stuff, but this is way more fun. Add as much cameras as your frigate instance allows..

  • Surface Linux question
  • Had a custom kernel installed back in the days, but the most hardware 'just works' using vanilla Ubuntu 22.04.

    I guess the camera doesn't work, but being a SP 4Pro, I use it mainly as a terminal or some coding with Codium and couldn't care less about the camera.

  • help with clogged Mk4 hotend?
  • Blowtorch will heat this up way too hot.

    Try to get it to a high enough temperature to insert filament to do a cold pull and repeat..

    Electrical heat gun (paint stripper) is hot enough. Gas based torches will change the stiffness of your material and you will regret it.

  • Controller Oriented Interface for linux?
  • This.

    Using a CEC link will make things even more simple, but that might involve additional hardware. Those raspberry thingies have native CEC on hdmi. For x86 you might have to look at some extra hardware.

    And of course, Kodi is an example of a 10 foot interface.

  • Used NetApp 6TB SAS for 38€???
  • NetApp makes storage devices, just like Dell's DataDomain.

    Looks like the ad is referring to a ST6000NM0034, a drive from Seagate. Personally, I like to stay away from that brand as far as possible.

    Have had good experiences with WD.

  • Unveiling the xz Utils Backdoor which deliberately opens our SSH connections for RCAs
  • Thanks for the pointer.

    This is really huge, but people don't quite understand that yet.

    If this wasn't caught, every system -running public sshd- could be hacked or abused/misused.

    And I completely agree with the last words, corporate should pay foss projects!

  • Amsterdam testing system that can remotely slow e-bikes down
    nltimes.nl Amsterdam testing system that can remotely slow e-bikes down

    Amsterdam is one of six European cities that will soon test a system that can remotely limit the speed of electric bicycles. Amsterdam’s traffic alderman, Melanie van der Horst, tested the system herself last week, NRC reports.

    Amsterdam testing system that can remotely slow e-bikes down

    Alrighty,

    So your system knows the exact situation and still is slowing down my bike, just at the moment I need to accelerate to avoid being overrun by that large truck heading into me.

    How stupid are these folks? We've got rules, when people don't follow those rules, you fine them. Case closed.

    No system to prevent a bike speeding, teach people to obey the law.
