whoooooo123 commented on USB inventor explains why the connector was not designed to be reversible (2019)   pcgamer.com/usb-inventor-... · Posted by u/thunderbong

> Making USB reversible to begin with would have necessitated twice as many wires and twice as many circuits, and would have doubled the cost.

This is... not correct.

You can make USB reversible with 1 extra pin and 1 extra wire. Grounds on pins 1 and 5, data on pins 2 and 4, and VCC on pin 3. Then have those pins on both sides of the plug and a socket with a single set of contacts on one side.

That's BASICALLY what Apple did with lightning.

Then you implement auto crossover detection, (edit: Gah! you don't even have to do that just flip the flipping wires) which had been around for years and is dirt cheap, in the hub. It would have been like, six, more transistors in the hub IC.

edit: I completely forgot that reversible USB 2.0 plugs already exist and use a simpler (and cheaper) method. They just tend not to be so reliable because of the thinner materials and the fact that they're not spec-compliant so they tend to be grey market jobs made for the lowest price possible.

Here is one: https://www.amazon.com/Tripp-Lite-Universal-Reversible-UR050...

No doubling of wires or circuits required, just a thin double-sided PCB.

Was the connector form-factor inherited from an earlier project and the players didn't want to design a new one?

The problem with USB-a isn't that it's non reversible, it's that it's non-reversible _and_ rectangular, so it's not clear at a glance which way round it should go.

All they had to do was make the connector have a non-symmetrical shape so that it's immediately obvious which way round it goes when you pick it up - you could do it without even looking. Think of how much time we'd have collectively saved with this minor design change.

Jesus people, stop buying from this DRM-ed cloud crap. The only acceptable formats for ebooks are LOCALLY INSTALLED PDF and epub. Steal them if you have to!

Or just buy real books. I ditched my Kindle years ago and have never looked back.

Nothing beats a hardback.

“Talking about themselves as anti fascist is a far-left thing”. Where are you getting that from? It’s ridiculous
whoooooo123 · 3 years ago
I think the argument is that the further left you go, the more likely you are to explicitly describe yourself as an anti-fascist and make a big deal about your opposition to fascism, as opposed to just quietly disliking fascism like most of us do and not feeling the need to announce it.

Like all sane people I oppose fascism, but I don't put "anti-fascist" in my Twitter bio, wear antifa t-shirts, or run around loudly telling everybody about how much I hate fascists, because why should I need to? Of course I'm an anti-fascist, who the hell isn't? It feels as unnecessary as having to tell people that I'm "anti-genocide" or "anti-pedophilia".

It's also true that communist regimes have always used "anti-fascism" as an excuse for their atrocities, just like fascist regimes have used "anti-communism" to justify their atrocities. The original Antifa was an offshoot of the German Communist Party, and (as GP pointed out) the Berlin Wall was officially called the "Anti-Fascist Protection Rampart". That doesn't mean that all anti-fascists are communists, but history is what it is.

Don't take any of this as my denying that there are still fascistic forces in our world that should be opposed. If "anti-fascism" is an important part of your identity and you feel the need to tell the world about it, good for you, I'm not going to stop you, but personally I don't see the point.

whoooooo123 commented on Friendship Forever   secretorum.life/p/friends... · Posted by u/dheavy

The part about remote work removing a driving force for friendships hit me pretty hard. In February of 2020, I had a dozen or so really close friends that I would see every day. We would laugh together, get food together, and work on hard problems together.

In March of 2020, we all started working remotely and I haven't seen any of them since. Even if I wanted to, almost all of them have moved to other cities, states, or countries. Most left the company we were at (including me). We have a Discord server where we all still talk and chat, but it's a cheap imitation of what we used to have.

Now, I work with a team of people who are completely scattered geographically. Maybe once every few months I will see one of them in person if they happen to be in the area. They feel like strictly co-workers- I don't think we've ever really laughed or just goofed around that much, and certainly aren't hanging out outside of work hours. I wouldn't be able to call one of them up in a time of crisis and ask for help.

I miss my friends, and the simple solution would be "go find new ones!" but, like this essay points out, that's not exactly easy and there's a "blind spot" about how hard it can be. There's also still a pandemic going on- I haven't caught COVID-19 yet and don't plan on it. Any sort of friendship that would involve physically being near other people on a regular basis is just asking for it. To me, getting sick is not worth having a friend, even though it is wrecking my mental health. I know that equation is different for other people.

How old are you? If you're reasonably young, and vaccinated, you really don't need to worry about COVID this badly. Practically everyone I know has had COVID by now and for most of them it was not much worse than catching a cold.

COVID is going to be around forever. I don't know why anyone is still letting it disrupt their lives.

Are there really 10M active MetaMask users and 50M active Brave users? I mean, that's a lot. Twitter has ~200M daily active users and it's a service everybody knows.

I've installed both products maybe five years ago, tried a few things and gave up, and there's no incentive in sight that would make me use them again. I suspect they're still counting me as a user on the brave web3 frontier because I have some wallets whose private keys I've lost ages ago.

Plenty of people, myself included, use Brave as a privacy-focused web browser without using or caring about any of its crypto features. Hell, I've been using Brave for years and I'm still not even sure what its crypto features are.

> Blockchain technology was innovative and is interesting, but still early stage.

[1]

- Cryptographer David Chaum first proposed a blockchain-like protocol in his 1982 dissertation

- Further work on a cryptographically secured chain of blocks was described in 1991 by Stuart Haber and W. Scott Stornetta

- In 1992, Haber, Stornetta, and Dave Bayer incorporated Merkle trees into the design

- The first decentralized blockchain was conceptualized by a person (or group of people) known as Satoshi Nakamoto in 2008.

Even the most charitable interpretation makes blockchain 14 years old. In computer tech terms it's old, and there are still no discernible use cases for it. Because, as the article succinctly puts it: "technologies, processes, people, regulations, laws, industry, and the entire legal and societal foundation that underlie an organisation, no matter how imperfect, aren’t 'web2', and that they can’t just be converted to 'web3', whatever that meant."

> don't understand anything about technology.

Oh, they understand it very well. THey also understand that humans are gullible.

You are wrong. There's at least one discernible use case for Blockchain: the facilitation of crime. To that end, it's been very successful.
