Came up with something similar a for myself: https://mprimi.github.io/portable-secret/ it was well liked by HN: https://news.ycombinator.com/item?id=34083366

Very cool!

Here’s something similar-ish but using symmetric encryption (i.e. password):

Shared something very similar on HN a few years ago. The entire source code is about a hundred lines, which makes it easier for folks to review and trust: https://news.ycombinator.com/item?id=34083366

There are some restrictions.

I had the foolish idea of installing a Tesla charger at home to charge my Bolt. I’ve been unable to ever use it.

The wall charger works fine with Teslas. My car and adapter charge fine at Tesla superchargers.

But the home Tesla charger refuses to charge my Bolt. (Yes I disabled vehicle restrictions and tried all sorts of combinations of settings for weeks before giving up. Tesla support was useless of course)

Restriction or bug, same difference.

A NACS to CCS (L3) adapter won’t work with L2 chargers, you’ll need a NACS to J1772 adapter.

This is the one I use https://ev-lectron.com/products/lectron-tesla-to-j1772-adapt...

They make a "universal charger" for this express purpose. It even has the adapter embedded in the holster, so you can either grab just the NACS connector, or the connector + J1772 adapter in one smooth motion.

Just don't try to use that adapter on another NACS connector like the Mobile Connector, it'll get stuck and you'll have to do some magnet shenanigans to get it off (ask me how I know...)

NACS on Level 2 has the same number of pins, but speaks a different protocol than J1772, so just a normal "dumb" adapter won't work. You either need a Connector that can speak J1772, or a TeslaTap.

If you’re using the same adapter successfully at a supercharger, you have the wrong adapter for AC (level 1/2) charging.

Really gross. I have a gen 1 charger and it's dumb as bricks. Basically just a giant relay.

I guess I could see why you might want to restrict who can use your charger, but I really prefer the "dumb as bricks" version I currently have.

> 5.9k stars, 727 forks, 132 contributors: https://github.com/nats-io/nats.go

That's the NATS Go _client_.

The server project is https://github.com/nats-io/nats-server 17k stars, 1.5k forks, 160 contributors

Look at the contribution history, basically all active contributors work for Synadia: https://github.com/nats-io/nats-server/graphs/contributors

That's not a healthy / functioning open source community. Less than 30 people have made more than 10 commits; most of the 160 were "drive by" who fixed a single small thing.

Good point!

On the face of it, that sounds healthy. But dig in further, and you discover that only the top 10 or so contributors have enough activity to make their personal contribution graph anything other than a flat line on zero.

The vast majority of the work here is being done by a very small group of people - likely those paid by the commercial sponsor (a random sample of the top few suggest that well over half of those top contributors fall into that category).

If those people aren't paid to work on the project any more, it will likely die very quickly.

This is something I always do manually and it is annoying. The number of contributors we see on the front page of a project on Github is misleading and can easily be faked by a malicious actor because a user who corrected a typo 5 years ago is counted as a contributor.

Github should really improve that.

Mastodon is another one (ActivityPub / Feediverse)

> never really understood how just adding extra invisible stuff to make the equations work is justified

IANAP but here’s my understanding.

At the end of the month you spent $2000, you’re not sure how so you track down your expenses:

  - rent $500
  - groceries $120
  - gas $80
  - …
  - unknown: $123

That ‘unknown’ is dark matter. It’s a placeholder. It’s there and makes your total but you can’t explain it yet.

What if dark matter is actually 10 different items? Or you have rent and gas wrong, or rent and gas inexplicably depend on each other in some way?

My anecdotal evidence confirms this. Friends in my home country are hooked on Telegram meme groups and as a result they’re spreading [Russian propaganda] conspiracy theories at alarming levels.

(Russia is really good at weaponizing memes but I don’t meant to single it out, the US has also been very successfully influencing the same country for decades via Hollywood movies for example)

Stay humble

  - There is someone else that is better at X than you are
  - The person not so good at X is probably better than you at Y

Indeed. Borg for example is e2e but able to dedupe.

My bookmark archive is 10TB but deduped on-disk size is 100GB because most files are the same across backups!

https://www.borgbackup.org/

That’s not the same thing at all.

Same thing as what?

Parent was asking about deduping encrypted data.

Someone said (wrongly) it’s impossible and I shared a popular project that does exactly that.

“Not backing up the same file twice” is not the same thing as deduplicating encrypted data, as encryption has no relevance there. You can do that with or without encryption.
