GNU-Linux
  • What are you talking about? I've witnessed it several times now at work, especially regarding programming or EE. Have you not yet suffered through a programmer condescendingly explain trivial matters to others, especially to women?

    The post is obviously a hyperbole but it's not too far off from reality.

  • GNU-Linux
  • I don't think anybody is obsessed with it. It's a problematic behavior in many men, enough so that it's become a meme, particularly in the US.

  • We are a failed species
  • I've tried this. It's drinkable but not very enjoyable. 5/10

  • Why not serve fried chicken on Juneteenth? How is it different from serving corned beef on St. Patrick’s day?
  • I'd argue it depends on who is serving it and what their intentions are. I don't think it's necessarily bad. I went to a local Juneteenth celebration and the food stands were serving some fried chicken, collard greens, jollof rice, etc.

    Routing USB signals on 2 layer flex PCBs
  • I can't change the thickness. I might try cross hatching the ground plane (suggested in the SE) and seeing how that affects the impedance as well.

  • Routing USB signals on 2 layer flex PCBs
  • It's a USB adapter for a dock. It has a nonstandard pinout, so I made an adapter for it.

  • Routing USB signals on 2 layer flex PCBs

    Does anyone have any advice on routing some high speed signals on flex PCBs? I'm looking at jlcpcb because of the low cost but I'm having difficulty getting impedances to be decent.

    My requirements are:

    • 45 ohm single ended impedance (maybe? Def doable)
    • 90 ohm differential impedance (usb spec)
    • 5A current on power pins

    But if we look at the capabilities: https://jlcpcb.com/capabilities/flex-pcb-capabilities

    • 2 layer
    • substrate thickness (PI) = 25 um
    • 1 oz pour thickness = 35 um
    • min trace width/spacing = 4/4 mil = 0.101/0.101 mm
    • ε = 3.3

    Is this feasible with this stackup? I'd like to do a 1 oz pour because of power traces, but there's also 0.5 oz (18um) and 0.33 oz (12um).

    For the differential signals, when I'm doing impedance calculations, I can get to roughly 70 ohms using W=100um, S=200um. I don't think this is good enough. I think I can get away using a 0.33 oz pour but then I'm worried about the power pins.

    And for the power traces, I'm needing 2.2mm, which is reasonable for the pins on a USB-C connector. But if I try using the 0.5 oz or 0.33 oz pour, it gets to be 4.2 mm and 6.3 mm, which seems impossible given the pins are tiny and very closely spaced together. Even with vias to the bottom layer, this seems problematic.

    Anyone have any advice here? This is just for a hobby project, so I'm really not looking to change fabs because of costs.

    Dumb question: how do I know if an open source project is trustworthy?
  • I look at the contributors on Github and check them out. I'll check out what else they've worked on and maybe see if they have an account on mastodon or twitter. Maybe I'll ask some friends if they've used or heard of the product, or know of the devs.

    There is indeed malware disguised as OSS and you do sometimes have to vet them. I'll skim the codebase and see if there's anything that looks weird or funky, but that's not perfect (like in the case of the xz) and some stuff can slip by.

  • When are police required to use their body worn videos and dashcams?

    I submitted a video request for any body worn video and in-car footage for the incident where SPD officer Anthony Belgarde pulled over a bus in West Seattle. But I was told by Edward Ocampo that no video existed for this incident. Is this a normal practice, to not record any video during a traffic stop?

    Edit: I filed a complaint as I believe this violates 16.090-POL-2, where cops in uniform performing traffic stops are required to have their cameras on.

    Edit 2: I did not get a confirmation email though.

    Edit 3: had to email them again to get a complaint number

    you don't need more 4GB of RAM
  • I was running out of RAM on my 16GB system for years (just doing normal work tasks), so I finally upgraded to a new laptop with 64GB of RAM. Now I never run out of memory.

  • [Resolved] After updating through both APT and the Software Store, I can't play mp4 videos with VLC anymore. The screen goes blank for a second or two then the audio starts playing without the video..
  • I'm not sure off-hand since I'm not too familiar with VLC.

    I would imagine it could be an issue in a graphics driver at the kernel (amdgpu?) or user level (mesa?). It could also be a problem in something higher up.

    I would recommend posting an issue in the VLC repo and see if you can get better support that way.

  • Need help setting up i2p in a Docker container

    I'm looking to try out i2p but I'm having trouble getting it going.

    I have a docker-compose container going with this docker-compose.yml:

    yaml version: "3.5" services: i2p: image: geti2p/i2p ports: - 4444:4444 - 127.0.0.1:6668:6668 - 7657:7657 - 54321:12345 - 54321:12345/udp volumes: - ./i2pconfig:/i2p/.i2p - ./i2ptorrents:/i2psnark restart: always environment: - IP_ADDR=0.0.0.0 - JVM_XMX=1024m

    The container starts up and the log outputs:

    $ docker logs i2p-i2p-1 Starting I2P [startapp] Running in container [startapp] setting reachable IP to container IP 0.0.0.0 Starting I2P 2.4.0-0

    But when I try to access the console, I'm seeing:

    $ curl localhost:7657 curl: (56) Recv failure: Connection reset by peer

    Is there anything else that I need to do here?

    [META] What are your thoughts on this community's moderation?

    I'd like some feedback on this community's moderation. Do you feel it's too relaxed? Too strict? Feel free to voice your thoughts in a comment below!

    I've tried to be very "hands-off" and mostly let the community decide what's acceptable by voting. I don't usually remove content unless either I receive several reports or if it's a clear violation of the rules/code of conduct. I don't know if this is the best path to take though.

    Boss moved resin printer into my office and it reeks (edit: resolved!)

    When I came into my office this morning, I found that my boss moved his resin printer into my office and the setup reeks of solvent (it smells like a hundred uncapped expos). Are these fumes fine? Or am I gonna end up with half a melted brain by the end of the week?

    Requesting items at a Costco?

    Has anyone had any luck requesting items?

    I normally shop at a Costco near my home but my family resides in another part of our state and they go to a different one. I've noticed that their Costco gets way cooler items (jagarico, black thunder candy, like air puffcorn, etc) and I'm tempted to try and request some of them. How do I get these at my store?

    The package wasn't at my entrance too, it was just on the sidewalk 😕

    Fwiw, this is the only time the UPS driver has left the package in that spot. Normally it's right next to the front door.
