The MIDI protocal. The technologies that use it have evolved in all sorts of ways, but the protocol has remained unchanged.
MPE and MIDI 2.0 would like a word zir
That’s fair. But the fact that MIDI 1.0 isn’t going away anytime soon shows how good it was from conception. From Sweetwater:
Because MIDI 2.0 coexists well with MIDI 1.0, it’s likely MIDI 1.0 devices will continue to be produced in the future if MIDI 2.0’s features are not needed for a particular application. In developing MIDI 2.0, backward compatibility with MIDI 1.0 was always a priority.
MIDI 2.0 is not about replacing the original specification but about adding features that enhance the spec with features users have wanted almost since MIDI 1.0 appeared.
The best inventions do progress with backwards compatibility
MIDI protocol for users might be good enough but for developers is a nightmare if you want to do advanced synthesis

The six classical machines.
- Screw
- Inclined plane
- … I forget the others
[off topic?]
I can’t remember the exact quote, but Robert A. Heinlein said of the DC-3 that it was the best airplane ever built, and that the only way to improve it was to completely redesign it.
I just like the idea that some things are perfect the way they are.
I know Heinlein had his problems, but in highschool I loved his books.
The line is in ‘Glory Road,’ a great fantasy book that takes pretty much every fantasy trope and kicks it to the curb.
I think sewing machines would count? They certainly got a hell lot more “portable”, but the basic design hasn’t changed much since the 1880s. Those things are little mechanical marvels
Well, for “normal” ones they changed a lot about the lower thread. Also there came overlock machines to make life easier for certain stitches.
But nonetheless, they are marvelous machines, I love them so much. It is mechanic porn, and granted, the design of the old ones was perfect. Don’t need all that plastic 😅
Old refrigerators before all the ice makers were added.
But super energy inefficient in comparison to what we have today.
Wireguard. I haven’t heard of any huge changes to it over the years. And it somehow just works
Meanwhile I just tried to set up a VPN connection for my laptop and can’t get wireguard to work properly
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.
The ones that maintain a whitelist of connections are the hardest to get through
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.
Microwave oven. It sort of just…appeared, and the design didn’t change much.
Well at first it looked and had a UX more like a regular oven, but yeah idk how much the internal tech has changed.
In my Flat we still have a microwave that does not have a rotating plate. Insteadt it has a spinning rotor in the roof that deflects the waves in order to cook food evenly. It works well but it is needlessly complicated compared to modern microwaves.
Most microwaves have a spinning wave stirrer in addition to the rotating plate. From the description here, it just sounds like either your plate rotation motor is broken or you’ve got a weirdly simple microwave.
Weirdly simple. It does not have a rotation motor. It is quite old.
This is the first time I’ve heard that they have a wave stirrer. I’ve never seen one in person.
Usually it’s not inside the same chamber as the food as then it would be a nuisance to clean. You need to take a microwave apart to see the wave stirrer.
The diagrams I’ve seen show the wave stirrer on the roof. The microwaves I’ve seen have the ceramic plate on the side where the magnetron is so there’s no space for a stirrer.
if the diagram’s any good, it should show the wave stirrer in the roof rather than on the ceiling of the food chamber. There’s typically a waveguide to take the microwaves from the magnetron to the top of the chamber, then the wave stirrer is at the end of the waveguide to vary the angle that microwaves enter the chamber at. There’s usually something to stop food splashing/spraying into that section, though, e.g. an extra few centimetres of waveguide afterwards with a bend in it.
I understand what you’re saying, I’ve just not seen one with any indication of a wave stirrer. They all just shoot the beams from the magnetron through a ceramic plate on the side if the microwave. The top interior of the microwaves I’ve used (even one ones from Samsung and LG) had no holes or vents. Maybe it’s just an American thing?
But maybe don’t take apart a microwave unless you absolutely know what you are doing. Otherwise, what you find may be shocking.
Of all the dangerous devices to disassemble, they’re one of the safest. A phone charger might still have 400V across one of the capacitors ten minutes after unplugging it (if you’re in a 230V RMS country, so have more than 400V peak-to-peak), but a microwave’s high-voltage section is only powered when it’s plugged in, and microwaves are so long wavelength that even if you reassemble the waveguide or outer case badly and leave gaps, there probably won’t be dangerous levels of microwaves escaping as gaps much smaller than the wavelength in question don’t compromise the Faraday cage.
RSS Feeds
So good, that Google abandoned their reader
That’s a badge of honor, if anything.
Yeah that’s how I meant it. It short circuits their business model.
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
Alternator Since its invention, the basic principle remained same, we are just finding a fancier ways to rotate it
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.
The pointed stick.
No, it was later improved by using different materials, better tools to make it and hardening it with fire.
Steel capped ends
Bendy sticks and string to launch them over 150m away.
Ah yes, trebuchets. A fine choice.
Lots of weight-training equipment. Bars, manuals etc.
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)
Potato peelers. The ergonomic handle was a big step forward, yes. But the basic design hasn’t (and likely won’t) change.
Wasn’t expecting this answer. Can you elaborate?
Show this to a person from 1900 and other than the plastic, nothing has changed.
I would happily argue that the plastic is a step down; metal potato peelers last a lot longer.
The metal ones last longer, but the Oxo ones (like above) don’t hurt as much.
