  • Yeah, the wine is completely ridiculous.

    Everyone knows the proper formula for cat longevity is tren, metformin, and a lil bit of creatine sprinkled on wet food. Keep ‘em swole.

  • [SUPPORT] iptables - rules for OUTPUT chain

  • PSA for those who haven’t read the docker docs in detail: If you run docker with UFW or any other iptables based firewall, it will often overwrite and break your firewall rules.

    Many people running containers on public hosts get burned by this, because they’re expecting their firewall to block outside traffic from hitting the container.

    Firewalld is a solid alternative that does not suffer from the same failure model; highly recommend.

  • [SUPPORT] iptables - rules for OUTPUT chain

    Jump

  • Been a minute since I touched iptables, but IIRC, not quite that simple.

    You’d want to allow outbound connections to destination ports of 80/443/22 and then also allow responses from any established connection (because the server replies won’t likely be going back to your port 80/443/22 as their dest). Unless you’re running dns over https across your whole system, you’ll need to allow that too.

    Nothing against doing things the hard way, but you might like OpenStitch if you’re looking to control traffic in a practical manner.

  • Yeah. They’re probably hardened to some degree, but a green laser with at least a watt of power will still cook ‘em pretty good.

    E: Obligatory warning that a 1+ W laser will also cook your eyes pretty good.

  • Did I miss something? They didn’t post any real evidence at all unless there was a link I didn’t find.

    What the post is describing sounds exactly like the post getting flagged by users, then uncensored by the mod team later on.

    I’m both an HN user of more than a decade, AND a massive HN hater. I’m predisposed to assume the worst, but there’s very little meat to this allegation.

    Is audiophile bullshit cheating?

    Jump

  • I know you’re playing devil’s advocate, but to play devil:

    In a theoretical world where you can manage to perfectly beamform the entire 20-20k Hz frequency range into a single node (or pair of nodes around the ears)… you’re still just re-condensing the original reference signal at the site of your beam target.

    And if your idea of peak quality is to hear the reference signal loud and clear, it might be marginally easier to set up some well-tuned speakers in an arrangement relatively free of resonance hotspots and then crank up the volume.

    So, how do you “crank up the volume” for that? Glad you asked; simple really: we need to apply a gain filter. To do this, we set up an array of batteries, and then connect only the positive side of the batteries to our audio cable. Positive electricity is bigger than negative electricity, so adding positive electricity to the cable means the speaker sound gets bigger.

    In short, all you need to match the quality of a hi-fi beamforming speaker system can be replaced with a few 9V batteries connected to your tuner with a paperclip. Thanks for coming to my audio engineering TED talk.

  • what's the coolest thing you have ever programmed?

  • In high school, we used to play a game colloquially called Spoons/Assassins/Spoon Assassin/Marker tag. Long story short, everyone playing gets assigned another player as a target. You tag your target on the back of the neck with a spoon or marker to “kill” them + take over their assignment. Rinse and repeat until only the winner is standing.

    Major catch here is that for the game to work properly, the targets have to be chained in a loop, so there usually has to be a trusted individual running the game who can validate the assignment list.

    So I scraped the online school directory to pull names, emails, and school photos of everyone. Then I built a Java Swing app to track a list of who was playing, and the app would shuffle a random list and email everyone their assignments blindly, photos included. Flash forward a few months, and eventually we had a full roster of ~80 people playing across grades, which was ~10% of the student body.

    Unfortunately, a group of freshmen started their own take on the game, which devolved into mauling one another with Crayola markers and Sharpies. The principal catches word that I’ve been running a ring, and brings me into his office to tell me to shut it down.

    Uncharacteristically for my teenage years, I went all-in on diplomacy. I plead my case, tell him I’m not involved with the freshmen, hear out his concerns, volunteer to modify the game rules, and point out that our group been playing for months without issues. No dice; the dude was a jackass with a chip on his shoulder. So we come to an impasse, staring at one another in silence.

    Eventually, to break the silence, he asks about a stray bandage I have sticking out the top of my shirt. I’d had a small melanoma removed from my collarbone that week, which was caught as early as possible and removed without issue. Seizing the opportunity, I tell the principal “I have cancer”, and immediately walk out before he could formulate a response. Poor dude went white as a sheet. Good times.

    Bit of a lame ending for the app, but building it taught me the skills I used to jump-start my career, and drove home the point that software isn’t an end unto itself — it’s the way people use it to come together that makes things great.

  • Mirroring git repos with force push protection?

    Jump

  • Dangling commits are unlinked objects, and happen pretty frequently if you’re using hard resets instead of explicit git reverts.

    Not arguing that it’s good practice but it’s very common.

  • Mirroring git repos with force push protection?

    Jump

  • Great answer on the whole, but worth noting that both Git’s standard CLI client and most hosted git services do run periodic GC to prune dangling commits.

    I second the suggestion to take periodic snapshots of your mirror. Because the majority of file contents will not be changing over time, you can make these snapshots very disk-space efficient by taking binary diffs of the tar’d repo using rdiff or the like.

  • From an engineering perspective, tying the backup camera to the CAN (and by extension, telemetry units) dramatically increases the possible modalities of failure.

    The two are absolutely connected.

  • The second-order effects are not the fault of the regulators trying to make cars safer

    This is where you’re losing me. The second-order effects are within the purview of those regulators and should have been addressed in-hand with the mandate.

    Why would the automakers be willing to comply with safety regulation but disregard telemetry regulation?

  • In a vacuum, sure.

    In practice, the government has moved from speed cameras (benign monitoring) to ALPRs (pervasive surveillance) without the public blinking. In practice, many auto manufacturers (Telsa, Hyundai, GM brands) have made it a matter of regular policy to ship home audio and video data from drivers’ cars to use for marketing and surveillance.

    Backup cameras are a small drop in the bucket compared to other transportation design choices if you’re serious about a Vision* Zero endgame, and in my book, the potential for abuse makes them a liability rather than an asset towards that end.
