Salmonella Sickened 171, the Biggest Outbreak From Raw Milk in Years - The New York Times (Free article)
  • I wonder if they can get sued for false claims. They claim to test every batch before bottling. And although there's a warning, their claims imply that the milk is free of pathogens.

  • Do you ever use the Internet Archive for anything?
  • I use it a few times a week, usually while at work. Normally to visit a dead link or to find old or outdated info.

  • Sardonic Grin
  • It looks like poison hemlock (Conium maculatum).

  • Grāpple
  • I remember these. Tried them once and never again. It's a cool gimmick but pricey.

  • Need some advice, two ppl in my family who did interviews has opposite views
  • First paragraph is good. Second paragraph could be rephrased IMO.

  • What is a good starting point for learning about quantum fields
  • Nah, just the basics is fine. I would recommend Griffith's and then moving on to Shankar.

  • What is a good starting point for learning about quantum fields
  • It's also really important to remember that QM is really a formalized algebra of probability/stats, so it's really really important to get a good grasp of that. QFT and all that comes after understanding the basics. It's a fuck ton of work, but I think it's rewarding.

  • What is a good starting point for learning about quantum fields
  • I'd really recommend going through the basics about learning QM. Specifically: classical mechanics, a very good stats & probability math course, calc prereqs, intro to QM, intro to thermal/stat physics, maybe an atomic course, intro chem course. I'm not sure of the exact steps, but as a physics undergrad major, it'll "click" after a certain amount of prereqs and if you need any help, feel free to PM me and I'll gladly be of assistance (as far as I can remember, at least).

  • anyway to block lemmy.world?
  • Blocking the instance, as you've done, will filter LW from your feed. If you're using Sync, you can also filter it through the app.

  • anyway to block lemmy.world?
  • Find an instance that is defederated from LW

  • anyway to block lemmy.world?
  • Just block the instance?

  • Is anyone else highly concerned with the SCOTUS ruling that the POTUS is immune from criminal liability?
  • Yep. I'm so over American politics and I think the nation is headed in the wrong direction. I feel that the people are powerless against changing our trajectory. I had been considering doing a PhD abroad and this is really pushing that decision now.

  • Recommendations for a quiet and cheap muffler?
  • I don't mind the extra few pounds. The bike's already a heavy pig 🐷

    I'm gonna have to keep an eye out for a used stock muffler

  • Recommendations for a quiet and cheap muffler?

    Anyone have any recs for a quiet and ideally cheap muffler?

    My bike came with a Leo Vince X3 and it's a little too loud for me. Is the stock one the quietest?

  • It's spam. OP is blasting the link everywhere

  • Are Tetra Paks actually recycled?

    Assuming my municipality accepts it, are they actually being recycled?

    I see them being touted as recyclable. However, it seems like it would be difficult and resource-intensive to recycle but I'm not a recycling expert.

    Seattle’s Living Computers Museum logs off forever, as Paul Allen estate auctions vintage items
  • I'd gone to this museum probably 5-6 times and every time it was amazing. Grateful to have the opportunity but I'm so saddened that it'll be closing for good. I wish Gates, Bezos, or any rich tech billionaire would've stepped in and tried to buy it out.

  • Orca Tap to Pay Now Available on Google Wallet
  • Has anyone tried this yet? I'm tempted to convert my physical card over but I'm worried about my phone dying, etc.

    Update: I bought an additional card (Wallet only) and it's working well so far for the light rail. I also added in a multi ride ferry pass and it correctly** handled that as well. Pretty happy about this so far, aside from being so very late.

    ** The screen on the turnstile says there's an error, but it correctly deducts from the pass and lets me through. The wallet app doesn't actually list pass uses remaining but myorca does.

  • 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.

    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.

    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

    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?

    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.

    Bridge port sometimes doesn't show on DHCP leases. Why?

    I noticed that occasionally the Bridge Port doesn't show up under Webfig > IP > DHCP Server > Leases. If I ping the IP from either the router or from a device on the same network, it repopulates the Bridge Port.

    For 192.168.88.248, it looks something like this:

    !bridge port not showing

    Then when I ping it, it'll correctly show ether5. Why is the behavior like this? Is there something that I can change (a timeout maybe?) so it always populates this column?
