    I’m surprised that I’m the first to say “p-trap” drain. Self-maintaining, no moving parts, affordable as anything, protects the indoors from sewer gas, catches rings. Chefs kiss 200 years old and still great

      I mean this thread is about tech that was perfect from it’s inception to the point where it didn’t or barely improved. Nothing could be further from the truth, transistor tech has had literally trillions of dollars and millions of smart people’s careers poured into it, and semiconductor IC manufacturing is now the most complicated single activity that our species does.

    Internet Protocol.

    ipv4 remains dominant.

    tcp and ip merged in like 1973, and it lived in labs till 82 or 83. after that its been 40 years of nearly perfect ip spec

    Lego. Lego from now will still mate with Lego from 40 years ago without a problem. Apart from a growing number of shapes, the basic blocks are still the foundation of everything sold today.

    Wireguard. I haven’t heard of any huge changes to it over the years. And it somehow just works

      My work WiFi blocks WireGuard and OpenVPN connections, which is a huge bummer. I just want to be able to connect to my NAS while I’m at work, but IT doesn’t want to hear that.

      At least I can still use IKEv2 with my commercial VPN, so my employer can’t see how much I browse on Lemmy throughout the day.

        I may be wrong on how they “detect” VPN traffic but the lazy way would be to block the common “default” ports used by those services. If they are just blocking this port you could change what port you use. While it does come with its own issues as its a common scanned port changing the port to something like 80 or 443 and “look” like normal internet traffic. Might get around their block.

          There’s a few ways to “detect” VPN traffic, and you’re missing some but port blocking is one of them. Rerouting over 443 is a possible workaround, but depending on the network architecture they can still detect VPN traffic using deep packet inspection.

          Blocking ports is a very simple mechanism to prevent things and it doesn’t take long for a business to grow into IT management that involves more sophisticated methods like DPI.

          VPN protocols have distinguishable packet headers/metadata/handshakes/etc. DPI can easily identify and block those, or any other known protocols, if they have it configured to do so.

            Ah nice to know. I’m just an amateur hobbyists. I just remember years ago the company I worked for(somewhat large) blocked ports 80 and 443 but left almost everything else open. Stop employees from browsing the web. I went home hosted a web page served on some random high port that worked as a proxy and loaded pages I wanted then used it to play flash ( shows my age) games at work to kill time. Looking back guess I could of gotten into some shit but no longer work for them. It was a fun time though.

    It’s very niche, but the only thing I could come up with is Kvevri, a traditional Georgian winemaking vessel. They’re sold today (and still used for their stated purpose, aging wine), I’ve personally seen kvevris with the exact same shape buried in a wine cellar of 12th century monastery, and at least going by the article they’re like 8000 years old, and haven’t changed much in that time.

    My other ideas were:

    • Bricks (turns out the earliest sun-dried mudbricks, which are very different from modern ones)
    • Concrete (turns out it changed a whole lot since the Romans, modern concrete is much easier to pour, sets faster and is much stronger)
    • Nuts & bolts (initially were hand-crafted and non-interchangeable - yuck!)
    • Knives (I’ll let knife enthusiasts speak about that one)

    Solid body electric guitars- the first models have been in continuous production and are still available.

    https://en.wikipedia.org/wiki/Fender_Telecaster

    https://en.wikipedia.org/wiki/Gibson_Les_Paul

    There were earlier “electric guitars” but I’m thinking all inventions build on previous creations. I don’t think you’ll find many pure answers to OPs question. I think the closest you’ll find is going to be an advancement that produced a single step change in design that flattened the innovation curve forever after. I think the microwave oven was a great example.

    Electric fuses also come to mind. Little has changed since 1890.

      Really? I tried a bunch of time and don’t see the appeal. I haven found any like category filtering so I can’t subscible to like just tech or whatever. I think I’m doing it wrong

        The goal is to treat the various sources as potential sources, just like you subscribe to communities here. Instead of subscribing to a tech community, you can subscribe to the various tech news sites that you enjoy.

        you are supposed to get the feeds from the sites you visit, and build a single feed from that. basically build one feed from the various communities you follow.

          I want a scrolling news crawler thing on my home assistance dashboard and getting a functional rss integration working with it has been more challenging than anything else I’ve done and I’ve automated a lot, put together an entire camera and alarm system together for my residence, made a little dopamine game that shows me my daily score for Todoist tasks I get done, etc, etc. I think it frustrates me so much because I thought it would be a fun side project to work on between more challenging pursuits while learning the system and it’s all that still persists.

          Edit: looks like this guide just came out a month ago, maybe it will help me get there. https://youtu.be/CK5tyvrt7pw
