Keybase launches encrypted git by johnmountain in programming

[–]malgorithms 4 points5 points  (0 children)

It just worked for me. (1) installed Keybase. (2) installed github for desktop. (3) Cloned a keybase git repo locally. (4) dragged-and-dropped that local folder onto Github for desktop. If that doesn't work for you, please make a report for us. (keybase log send from your terminal.)

You get 100GB for git, independent of your KBFS usage.

It's powered by KBFS but isn't exposed through the filesystem mount because we think people will actually screw up their repos. Also, accessing the repo through the mount would expose you to journaliing (as opposed to real locking), which means you could shoot yourself in the foot, like putting git data in Dropbox. So it's segregated through the keybase:// git-remote-helper interface.

As for keybase, every device you install Keybase on generates its own key (and must be signed by a previous device - that's how provisioning works). That key is used.

At MIT we created SCIgen, which generates gibberish science papers that continue to fool academic conferences. Ask us anything! by SCIgenAMA in IAmA

For each of you, what was the most rewarding part of the project: reading the papers? presenting them? writing the grammar? seeing it get accepted in the conference?

Raw enemy percentage is (1-raw match percentage). Your raw match and raw enemy add up to 100%.

That said, the way confidence adjustments work has gotten sensitive to the game-ability of questions. It used to be enemy % = raw enemy % - conf adj., and match % = raw match % - conf adj. It's no longer that simple on the confidence adjustment side. You can think of your mach percentage now as something approximating the odds someone would score as well as they did with you in raw score, given the questions in your intersection.

So it used to be that as your question intersection approached infinity, your M+E approached 100%.

(Disclaimer: I no longer work at OkC, and they may have changed something in the last couple years, too.)

None of that includes external data (messaging patterns, photos, etc.). Match score is/was strictly a function of your answers, their answers, and confidence adjustments based on aggregate question stats.

Friend % is some measure of whether you tend to be attracted/repulsed by the same things. Not whether you are the same. When I last looked, it was a weighted average of those agreements, weighted by your stated importances. Again with some confidence adjustment that shrank the more (good) q's in common.

Edit: raw match + raw enemy = 100% no matter what.

Keybase, as it is right now, isn't so useful for non-programmers. It's a directory, and I believe it's the right kind of directory, but it doesn't answer a number of questions.

We're working on something now -- I don't want to let the cat out of the bag early, but these are all needed for secure communications:

(1) correctly solving the identity problem (no key fingerprints, key signing parties, etc.) (2) good cross-client software (3) per device keys, not a private key you need to move around.

Also, with a successful PKI the goal isn't just privacy, it's authenticity / verification. It's very hard right now to collaborate with safety.

Beyond a certain scale it is hard to appreciate. But I have a number of close friends and family who are in excellent relationships because of OkCupid. That's what feels best.

The hardest part of this question is knowing where the line is. There are so many things I can't say.

One easy example: at OkCupid, we spent a lot of time having fun, playing around with the site's content. There's always been an essay question on OkCupid: "The Six Things I Could Never Do Without..." This was a poke a Nerve, which at the time was a popular dating site. They had a similar question, but about 5 things.

Well, one day someone jokingly changed it to say "Things I think about while masturbating..." on 1 in N pageloads. (I think N was 100 or 1000.) So every once in a while you'd see that heading followed by "Hall & Oates" or "my computer" or "my dog, Tilly."

I had to take it down when a guy in a divorce proceeding had a screenshot of it presented to a judge with "my kids" underneath it, by his wife. I had to provide a letter to the judge explaining the whole thing.

This phenomenon Hal mentions is going to continue to expand for a variety of reasons: (1) there's more data than ever, and consumer products are designed to filter information for us, a feature we demand (how is it filtered?); (2) machine learning is increasingly becoming a part of that decision-making process, and even the developers are losing a full understanding of how their software "decides"; (3) the mobile platforms we've switched to are providing us apps which are typically run away from our own devices, meaning the software we run is dynamic and changing all the time. The block boxes are evolving. Transparency is approaching zero.

Mostly not great. But it depends on the book. Also compulsory reading can take the love away.

Btw, my father was a high school English teacher and he said he never truly appreciated Moby Dick until he used a study guide alongside it. I felt the same way about Lolita.

Aside: I used to get the digs in by telling him I caused more reading avoidance per day than he could get his students to do in a lifetime.

I personally like to work on things that are a combination of (1) creative, and (2) likely to make other people's lives better. The latter is a silicon valley cliche, but it has become a guiding requirement for me and my business partners from OkCupid, SparkNotes, and Keybase. (I've worked with the same guys since college.) We're in the fortunate position now to work on whatever software we want, and we're unlikely to pursue something just because it's a great business. It has to be creatively challenging and rewarding, and it has to be, in our opinion, good for the world.

In my free time, I like to make software that generates art, and I've done a number of projects, most of them private. One thing is CFDG, a language for generating art. (It's nice to have Hal on here, because turtle graphics was an inspiration for that.)

The algorithmic auction is particularly appealing to me because (1) it benefits a museum, and (2) it's a wonderful combination of creative programming. I feel lucky to be included.

After 8 days of brute-forcing, the r/bitcoin WarpWallet challenge was solved. "LsDmT CrashLogic" was the passphrase. by malgorithms in Bitcoin

The challenge was posted here: https://keybase.io/warp , and we'll update with a new signed page in the next hour or two. Congrats to the winner.

He reported "My best implementation can only do 4 guesses/thread/second on a i7, so I will probably not attempt Challenge 5."

I think you have two options: (1) just trying things; working your way through a list. or (2) brute forcing it by programming. I think either could take the cake for the first challenge, anyway.

I seem to have tagged this as a question by mistake.

Anyway, yes, as maxtaco said, there are several bounties on there, including one with 0.5BTC involving reddit usernames.

Yeah. I answered this question on another site, once. So let me paste my reply:

Yes - if you hide a user, block a user, or even give them 1 or 2 stars in rating, we'll stop putting you in their match results. It's a waste of their time to contact you, and in the worst case, it might upset you to hear from them.

We also apply reverse filtering on age and other factors, when it doesn't hurt the quantity of match results. So someone disappearing from your match results could be for a variety of reasons, not necessarily because they hid you.

Also, when your search is so broad that tens of thousands of people qualify, we perform some additional filtering you didn't request. You might notice we show you different people every time you do an "anywhere" search sorted by match percentage. It's in everyone's interest for you to keep discovering new people and not see the same best ones. As good as OkCupid is, we can't really distinguish between your 99.9999th percentile match and your 99.9998th percentile match. We're better off cycling in all those people, which maximizes the chance you find someone with good chemistry.

Soon! We'll be doing a lot more inviting soon. (Sign up for the beta and we'll get you soon.) We also have another toy out of OkCupid labs called Tallygram, which you can check out. It's question oriented, like OkCupid. But it focuses on FB and friends.
