I don't see any mention of quantum computers in here so I thought I'd mention:

the NSA themselves are concerned that quantum computing will be a great threat to encryption in the near future.

Keep in mind that the NSA and god knows who else are storing encrypted communications to break them later.

Quantum computing will defeat RSA, DH, ECC, asymmetric crypto, but it will only weaken symmetric crypto (eg. AES) by a factor of two.

So according to my Internet research: if your symmetric crypto is twice as secure (key size) as needs be, it is future proof.

Also (and please correct me if I'm wrong) I believe the triple encryption Serpent(Twofish(AES)) available in VeraCrypt (TrueCrypt fork) even protects against weaknesses which may be discovered in any of these cryptosystems: they would have to defeat all three.

The confusion in your argument is rather simple. You construct the set of INTEGERS in a binary representation.

Then you flip them over to the other side,in an operation that you yourself do not fully understand.

The first number that you flip (0.1) turns into 0.5 decimal

The second number that you flip (0.01) turns into 0.25 decimal

The third is 0.75

0.125

and so on. You are creating a subset of the rational numbers, which is obviously countable. It is countable because you constructed it to be countable. You constructed something that was countable and then tried to prove that it is countable.

> WhatsApp say they use end-to-end encryption and they have a strong financial incentive to be telling the truth.

I'm not giving much to the various "whatsapp backdoor" allegations but I'm curious to why they'd have financial incentive to provide privacy.

Most of their userbase likely still doesn't care about security and they do belong to Facebook - so if anything, they'd have a financial incentive not to use effective crypto.

Does anyone here have an air-gapped computer setup?

I'm thinking of doing something with raspberry pi.

I'm stuck at the part where it communicates (for my purposes, small amounts of ascii) with a non airgapped computer without using USB or networking.

I'm thinking about giving both machines a little speaker and microphone and using high frequency pulses to transfer the text.

Why, you may be wondering?

1. Airgapped system is impervious to penetration

2. Can be used for literally unbreakable communications.
Breaking pgp like encryption would require a huge mathematical breakthrough in how prime numbers work and their discovery. It would also require unknown math geniuses to work for said secret department which is unlikely, most of the best mathematical geniuses are already known and tend to work at universities/public research/private research and publish their work there. Not saying this is impossible but it's really highly unlikely borderline crazy conspiracy.

Also, the fact that most governments tend to hack at the pre-encryption level and use social engineering to hack devices on encrypted networks kind of confirms they do not have the capability to break encryption.

There are so many ways that could be solved without the mac app store.

The great majority of users don't install new apps that's one of the major issues here. No one uses the mac app store to find and install new apps. So you are setting up a strawman.

Why do you think it made not effect on my sales while I was in the top 10 in the app store? If it had been on iOS it would have made a huge bump in sales because people actually use that app store on the mac they don't.

There is no real infrastructure cost to hosting your own app as there are plenty of platforms like Paddle who deals with all the complexity around taxes, payment etc. And Apple charges 30% it's not cost free.

So basically we are dealing with an app store which is mostly a ghost town yet forces everyone who want to make any real sales to be there just for the chance they can be featured which is the only real way of making good sales on there.
If it's airgapped, how do you use it for communication?
Ask HN: Help a windows SRE/DevOps engineer transition to a linux shop
Yes, shoot me, but I've been on a Windows SRE setup for some years and my next move is likely to a Linux shop and I'm quite worried about my lack of OS experience.

I've got a VMWare Ubuntu setup and an EC2 machine to play around with which I try to practice on just to get the hang of basic operations on navigating the terminal. What are some advanced commands I should be fluent with and will save my ass when firefighting? Surprisingly finding a lack of decent tutorials on this "ramp up a Linux newbie SRE/DevOps".

No more pi day, create ml day
3/14 is py day. If math is to be dedicated a day, I think it should be a day to show or think about concepts that can shape our future. Pi is a beautiful number but nothing more, Euler number is a better option in my opinion, but I think we should replace pi day with something more interesting, a day in which you can show some wonderful things about maths and science, a day to celebrate.

This was helpful. Thanks.

I did understand before how flipping changed the numbers into 0.5, 0.25, etc., but had missed that this process would only create rational, thereby missing the irrationals altogether. There's enough food for thought for me now. :-)
Quantum Theory, Groups and Representations – Peter Woit (Final Draft, 2017) [pdf]
Most of these issues aren't there with DNS based validation (presuming DNS-sec).

Though, that just shifts the potential problem towards anyone in the DNS-sec chain of trust. Most notably, the controller of the TLD (most often a government) and the registrar.

Thing is, those are also an issue with normal (http based) DV. After all, they could also change the A record for the domain they want a cert for.

I believe the current solution to all this is focused on detection rather than prevention (through certificate transparency and similar proposals). The idea being that any organization that isn't trustworthy will only get to pull of this hack once, in a short time frame before having their trust revoked.
You write beautifully.
Wow! This sounds like a very interesting role. Congratulations on being accomplished in both law and technology.
The CIA Cyber Security division is a joke compared to the NSA and Mosad.
From vault 7, "These techniques permit the CIA to bypass the encryption of WhatsApp, Signal, Telegram, Wiebo, Confide and Cloackman by hacking the "smart" phones that they run on and collecting audio and message traffic before encryption is applied."

1. O.k.--they are having a tough time with encryption--now. If they are intercepting information before the encryption, what's the point of encryption? (Yes--encryption is great, and we need it. It's just it doesn't seem like the CIA cares about it too much? We will need it for our everyday business.)

2. With the billions these Founders will make; how long will it be until they cave into threats by the CIA, NSA, IRS, etc., and just help the powers at be? "Here's the keys, or this is your backdoor. "I just don't want my meticulous life complicated." A poor man doesn't have anything to lose, so they might be the most trustworthy? (And don't tell me about morals. The successful founders have all bent the rules, or did something shady. You just need to dig. Yes--I'm stereotyping, and prove me wrong.)

3. An app, or hardware with real privacy will be hard to obtain.

4. A lot was redacted by Wikileaks. He redacted 10,000 spies. How do we know if he didn't redact information that would affect a IPO?

5. It used to be, "Don't trust a person with nothing to lose? For my seat, it's revered now, "Don't trust a 1 percenter who has a lot to lose." The government could make a Mennointe lose sleep at night with their shinagigans.

6. Yes--this is my dig at the "man". I don't believe 99.9% of them really care about their customers privacy. It's just grand standing. They care about money, and their lives, and maybe a few pet projects.

7. Assange has a lot of power at his fingertips. The only reason he hasen't been killed is they are scared.

8. Maybe the CIA shouldn't have computers at this point in history?

What you really want to understand is "where's pi", right?

Pi looks somewhat like this: 3.1415... "and so on". Let's ditch the 3.

0.1415... and so on. flipped over equals:

...5141

Easy enough, right? But pi had infinite decimals. Infinite decimals on the left side means what? You tell me :)

Infinity is not an element in the real numbers. All the irrationals, when flipped over, get absorbed into infinity - and infinity itself has no decimal representation. For people who are not in math, saying "and so on" is fine. But you can't do math on "and so on". "And so on" is a handwaving way of saying that you lack the mathematical language to describe whats going on. Which is fine, for casuals.
Just because you can't or won't use the sandboxing required by the AppStore, that doesn't mean that you should just not go to the MAS and ignore sandboxing... maybe you should _always_ sandbox?
Symmetric encryption not being broken doesn't really help you if the encryption key has been exchanged using a (presumably quantum-breakable) form of asymmetric encryption. Most encryption in the wild works this way.

My daughter who has Fragile X Syndrome, has used an iPod touch for years now. She's 14, and reads at about a grade one level. Between the screen reader that will read articles, texts and almost anything else on the screen, and the predictive typing and dictation, the iPod is an incredible device for her.

She has an Android phone, but it's not even close in terms of the accessibility options provided. Apple is excellent in this regard.
It would be very useful, but the display tech isn't there.

Crikey, I have heard countless stories from farmers, old construction workers and so on of coming across burial sites, ancient tools or dinosaur bones, where they have just covered the stuff up, buried it further down another hole or even destroyed it just because they had no care or knowledge of that stuff.

Some of the stories are pretty interesting (like caves with paintings of mega-fauna or sites of ancient fish farming), but some are also horrifying (One old bloke found a giant bone on his property while clearing scrub, he burnt it).

Great well for what it's worth I'm a "multicultural minority" and you're most welcome to express your views through the democratic process if you are Londoner. Evidently, Londoners don't discriminate based on such irrational nonsense and therefore he does, by democratic definition, represent the "majority".

This release is a bit early but it does run just fine, at least for the tests I did. I thought I'd make it available today because of recent interest in similar topics [1, 2].

I didn't think it was possible to get the whole thing into 500 lines (well, 502 lines but `Node.__repr__`, commented code and a number of other knick knack aren't needed except for debugging). At least top search engine results all point to using large tools and/or needing multiple passes of different kind which makes the subject sound complicated and hard to get anything even working.

Prompted by arcfide's project [1], I rewrote this one and the main part (boot.py) went down from ~600 to 100 lines. Of course, the features available are not the same but I'm starting to see why shorter code is easier to change globally. I'm much more willing to refactor (by hand) anything that only happens at most 6 times in the code! (And also maybe those other features aren't as useful as I thought.)

I wasn't sure how to count lines for this one. The generated tree contains no extra information (it can be regenerated from itself and the bootstrap grammar).

Well, SQL is a pretty complicated implementation of Datalog. I think it's easier to learn Prolog from first principles, since the pure subset is pretty simple.
>That seems a bit like goalpost shifting to me. What is the common usage of the term free will? I argue it is sitting in a restaurant and being able to order either steak or fish and that this decisions in neither deterministic, i.e. the choice is not a function of the state of the universe prior to the decision, nor random, i.e. the choice is not independent of the state of the universe prior to the decision.

I'd say that's a false approach, as it doesn't capture the actual thing we mean by "free will" -- even if it seems it does initially.

Neither dependent on the state of the universe nor random basically implies a soul. That is, an agent outside of the universe (that can still know part of the universe's history as it pertains to them and consider it when they take their decision but is not influenced by it directly to the decision). In the end, that could just be a random choice.

Now, the essential when we say free will is that the agent that decides a course is "me".

In other words, the ability to take different choices when repeating the experiment with the exact same parameters (state of the universe) is not important to free will. Neither is the ability to not be influenced by the state of the universe important. The only important aspect is "will" -- so it's not free as "whatever goes", but free as in "mine".

And it wouldn't be mine if, given my timespace-history as a person, I would take entirely different decisions given the same exact initial conditions. I'm me precisely because I take specifically a certain decision -- mine decision.

Using the term "free will" casually some might think that this means we can decide arbitrarily (e.g. if we could repeat the experiment with all other conditions absolutely the same, we could possibly see a different decision), but I think that's a wrong extension of the basic requirement: that the decision comes from the agent.

And the way that this is ensured in my version (and in line with both determinism and randomness in the universe) is that the agent IS the decision (the sum of their decisions) embodied.

Which is also symmetrical: given the same circumstances exactly (to the last particle being the same etc) we would make the same decision -- but on the same time, it's our history of passing through those exact circumstances and making those decisions that defines us (our "I").

What those going for the "arbitrary free choice" (possibility of different choice on same experiment) do is that they define the agent as someone outside the universe, e.g. dualism. But we are "me" and "you" inside the universe, and only to the extend that we have our exact personal histories.
One thing you could do is to exchange the keys in a nonstandard way. Phone or whatever. Obviously still breakable but at least not by a standard dragnet.
It doesn't look like anything to me.
