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
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
Alternator Since its invention, the basic principle remained same, we are just finding a fancier ways to rotate it
The six classical machines.
- Screw
- Inclined plane
- ... I forget the others
The headphone jack.
Lots of weight-training equipment. Bars, manuals etc.
Fire. No matter the fuel or the method, it still creates heat.
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.
The ones that maintain a whitelist of connections are the hardest to get through

🧷 Safety pin. There has been a little change in the safety cap but that's to save material not functionality or manufacturing.
The entire process is the same:
- Take wire, cut it
- Smash one end flat
- ?? (Bend the wire and fold the smashed end)
- Profit
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.

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.
Velcro? Inspired by nature's invention

Also outdoor grills don't seem to have changed much other than the material used to keep the fire going.
I read your last sentence as "good girls" didn't change much :3
