Not dismissing, I understand it is a hard problem. I'm simply saying that is the developer job to solve the issue. Similar thing happen in web development, there are tons of device, screen size, javascript framework, browser, os, all come with its own quirks. Is it suck ? Yes it is but it is my job as as a competent developer to manage all those complexity and solve the issue. From the user prescriptive, all they nee…

Yes, but because of "the suck" of web it's in some ways in a dismal state and that affects users. We can have only a small number of browsers that are well maintained; browsing is resource-intensive; web is extremely inaccessible to people with disabilities; web is notorious for security problems; fingerprinting can be seen as a side-effect of bad design; web requires a lot of man-hours to develop and maintain, like…

Sure you I wish that the state is in whatever it is that I prefer but thats unrealistic. As developer you have to be ready with whatever state you are in.

Sure, If there are only small number of browser or all of my user is not disabled, I would prefer that and my job will be easier but that is not realistic.

I have to be ready with whatever situation I've been dealt with. As developer my job is to solve problem and manage complexity. As a developer dealing with complex and hard problem is given.

In the end is the developer job to handle those issue so that in the perspective of the user, everything just works.

If I can't do that then I'm a failed developer.

I've heard that USB-C is intentionally designed to break the cable rather than the port, in situations where one of those must break. That's absolutely been true in my experience. It doesn't happen often, but I've dropped two phones while they're charging onto the cable. The micro-USB phone never charged the same again; depending on the cable, you needed to put pressure on it to tilt it in the right direction. My new…

I like the intent, but I would prefer ruggedizing them to the extent that neither of them breaks. Many automotive connectors, for example, are both inexpensive and extremely difficult to break either.

I want a phone that's small, light, is very powerful and has a battery that lasts a month.

Look what you are asking for is not economically possible. The connectors you are comparing with are much larger and don't even have close to the number of lanes as USB cables. It's a useless comparison.

The USB-C spec is an insane mess. The fact that every port used to be different is actually a feature, as it helps you identify which device supports what based on the ports it had. If you see an HDMI port on a laptop you can be sure it's going to output some kind of video signal over that. If you see Thunderbolt then you're sure the machine supports Thunderbolt. USB-C just jams all these incompatible standards into…

For work I had to connect a portable audio player to a USB audio amp recently. The amp is designed to plug into a regular computer, using standard USB-A at the computer end.

Since the audio player had USB-C we needed a basic USB-C to USB-A adapter.

Being audio only, it was low bandwidth, USB 2.0, no power transfer: we didn't need any fancy features from the cable. Just a plain USB-C to USB-A adapter.

I think we tried five different USB-C to USB-A adapter cables from different vendors before the audio player recognised the amp it was connected to.

It was so tempting to think there was a firmware bug, until we found out it was critically dependent on some mysterious, unknowable quality of the adapter.

Which automotive connectors do you have in mind?

I also recently bought a monitor with USB-C (Thunderbolt 3) which I can plug it's single cable into my DELL XPS and charge it, output 4K@60 to the display, and have my mouse and keyboard which are connected to the back of the monitor. The downside is when I want to use the same kb/mouse with my desktop, I have to unplug them from the monitor and plug them into the desktop.

The new Dell monitors have built-in KVM-s for exactly your use case. https://www.dell.com/en-uk/work/shop/dell-ultrasharp-38-curv...

Ah that would have been ideal in a slightly smaller size.

And the manufacturers would have never agreed on which ones to use. Starting with the zoo of power connections out there. It's a miracle I can charge my Dell XPS15 laptop using the work-provided Apple USB-C charger. Really.

It's just a question of regulation. I was under the impression, correct me if I'm wrong, that USB-C is the result of regulation as well.

Looking into it, it was more of a campaign. Letters of intent, etc. And it was only for mobile phone chargers.

To add to this I’ve just had USB-C cause a major inconvenience; it appears the USB-C cable I brought with me doesn’t play nice with the official Apple charger and my laptop is now out of charge. It’s an AmazonBasics cable that worked fine with an Anker charger for ages so I didn’t think it would be a problem. I’m in a remote country with no Apple Stores in sight and so my only alternative is to play roulette by buying random unbranded cables from the local mall and hope they won’t have the same issue (given even AmazonBasics is apparently not good enough for the Apple charger) nor blow up my laptop by being completely out of spec (happened to that Google guy that was testing cables, can’t remember his name now).

i used to think usb c was awesome and would lead to a 1 wire for everything world. Now i have 4 different kinds of usb c wire i need depending on usecase - passive usb c for charging my headphones since they didn't implement a resistor, active usb c for charging laptop,usb c for charging mobile(fast charging),usb c for data transfer/thunderbolt/video display what a disaster of a spec

The spec isn't a disaster. Vendors implementing is. The main problem is that OEMs don't give a sh*t about the spec and cutting corners whenever they can.

The spec should require clear labelling of SOME kind to differentiate between the different types of wires. I feel like that's been a common issue with the USB spec and one they refuse to address

I can sympathize with wanting to solve as many problems as possible and as well as possible and to provide a great user experience; however, our ability as devs is necessarily limited and that should be accounted for. Both the developer and the user are in this together.

Where I work many people have a docking station with a USB-C plug and a power plug molded into one connector. One cable to plug in, can safety deliver more power than USB-C can alone. With a bit of work engineers could have standardized an expandable cable. You have your basic USB-c cable with one fast (display port?) lane, one usb-3 data lane, the - basic cable in the article, enough for phones and light use. Then t…

What happens when you get a laptop with a slightly different port arrangement? Just throw out all the old docks? Seems like quite a solution from a manufacturer's perspective!

The reality is every time someone gets a new laptop they get a new docking station. Docking stations seem to last about 3 years. It is very nice when traveling to get to a remote office and hear "Joe is out this week, you can use his office - he even has a docking station that will fit your laptop". However it is questionable if his docking station will fit your laptop.

If connector N (usb-c or whatever) has enough bandwidth and a standard connector it would be really nice if we could give everybody that docking station. Even if we have to upgrade docking stations every few years, so long as I can mix and match I'd be happy.
