That ‘dude’ is the UK’s GCHQ. Of Bletchley Park fame.

Both ways are just notation. There’s nothing more real about 3/10 compared to 0.3.

Telling you otherwise might have worked as a educational “shorthand”, but there are no mathematical difficulties as long as you use good definitions of what you mean when you write them down.

The issues people have with 0.333… and 0.999… is due to two things: not understanding what the notation means and not understanding sequences and limits.

So the authors tries to be rigorous, but again falls into the same traps that the people who claim 0.9… != 1 fall.

“0.999… = 1 - infinitesimal”

But this is simply not true. Only then they get back to a true statement:

“Inequality between two reals can be stated this way: if you subtract a from b, the result must be a nonzero real number c”.

This post doesn’t clear things up, nor is it mathematically rigorous.

Pointing towards hyperreals is another red herring, because again there 0.999… equals 1.

This comment exemplifies the puritanical view that nakedness is somehow bad or impure.

Notice that the men in the paintings of Vallejo are also almost completely naked, hacking away at monsters with large weapons. Yet you did not point to them and say they were indecent.

I really hope that the rest of the world doesn’t take over the sex/violence sensitivities as are prevalent in the US.

$20 per year subscription? That seems pretty steep for what the app does.

Libsodium was independently audited by respectable reviewers. OP is spreading FUD for some very weird reason.

Libsodium is also extremely robust. The only crypto project I’ve seen that is as footgunless is google’s tink, and that isn’t available for a JS environment.

What’s great about libsodium is that it’s a single code base that works everywhere. RSA libs I’ve used have subtle differences when it comes to loading keys in different formats and also incompatibilities due to dropping leasing zero bytes for instance. Compared to that, libsodium was a breeze that just worked.

I agree. If you look at the Swift version of the library, it will generate and prepend the nonce for you automatically (if you use the right overloaded method). It will also strip it and use it during decryption.

My guess is they wanted to maintain compatibility with NaCl.

Libsodium is an amazing crypto library.

At my previous job, we used libsodium as the basis for all our crypto on web, iOS and android. This after a myriad of subtle problems and inconsistencies using multiple libraries for RSA/AES.

Libsodium is pretty opinionated, which is good. The only thing that actually came close in dev experience was google’s ~~Think~~ Tink library, but that isn’t mature on web and probably never will be.

It’s also hella fast.

Edit: corrected library name

It’s just OPs superiority complex for being on hacker news instead of “low-grade” Reddit.

Allowing drug users to legally and safely test their drugs results in more safety for individuals and less costs for society. In the Netherlands, private organizations have been testing drugs for users and helping the government track dangerous trends in the distribution of illegal drugs.

There’s a lot of recreational drugs like alchohol and (more recently in the US) weed that are legal to consume. The current system where drugs are only available through illegal means results in violence and huge amounts of organized crime, and a mixture of upper and underworld endangering citizens and politicians. We have huge issues with this in the Netherlands.

Personally, I find drug use abhorrent and I condemn everyone buying drugs illegally and propping up and enriching monstrous people, but I fully support legal drug testing.

Halfway logarithmically. Like 100 is halfway between 10 and 1000? That’s your argument irt the pricing?

If killing third parties wasn’t the goal, it’s very convenient that it killed so many third party apps, isn’t it?

It’s clear you haven’t seen communications from Reddit and the devs if you think that the people losing their livelihoods and projects they’ve been working on for years are somehow the bad guys. A lot of these devs would have been open to the proposed prices (or similar) if only Reddit didn’t give them only 4 weeks to come to terms with a multi-million price of doing business and implement any necessary changes. That’s a lot more than these apps currently make in revenue.

I think the thesis is wrong. It’s not that the average interaction is with familiar individuals. I’ve been a mod, lurker and commenter on a lot of subreddits. And on each of those, there are maybe 10 users I recognize and whose comments I see occasionally.

What is the case, is that on short timescales, the average interaction is consistent with what I expect from the community. The anonymity of Reddit has show that the specific face or individual doesn’t matter. It has a ‘friend’ or ‘follow’ option that I’ve never used and really never felt like I needed to use it.

Reddit actually became less familiar to me when I saw users tag other users in a post to share them with other users. The same with user specific subreddits. It’s when Reddit moved from content centric to user centric.

Check the ‘apology’ follow up. The person claims to be schizophrenic. Even the apology mail makes no sense and is full of paranoia and read like a group stalking delusion.

No one is upset because reddit wants to make the API paid. Several 3rd party apps were looking forward to working with reddit in this regard.

People are upset because:

- Reddit has been terrible and dishonest in their communication - Reddit is dropping Twitter-like pricing out of the blue - These prices seem to have the goal of killing 3rd party apps instead of merely being ‘realistic’ or ‘fair’, like Reddit is claiming - Reddit is dragging well respected devs through the mud and trying to make them look like the bad guys

It's only a pain if you try to look at it as a JSON tree instead of a knowledge graph.

json-schema has nothing to do with JSON-LD. If you want shape constraints on your JSON-LD data, you'll need SHACL: https://www.w3.org/TR/shacl/

JSON itself has a much simpler specification than XML, and feels much more lightweight for a lot of devs.

Under the hood though, linked data is all RDF.

Just do some basic functional programming. And/or do some of these challenges and don't feel like a cheater if you look at other peoples solutions: https://github.com/type-challenges/type-challenges

These fake-scanner pdf generators always use a huge skew. A tiny (random) bit of skewing makes it seem more genuine, but using the same exact large rotation puts it in an uncanny valley.

To be fair, their site is notoriously unstable and will break if fans look at it wrong.
