It's not just about the actual sound effects, it's also the writing. The movie clip the article uses as an anchor shows people using silencers to have a gunfight in public with bystanders having no idea it was happening. That's not just hollywood sound direction, it's hollywood giving a completely wrong impression about how good silencers are and why they exist

NP-complete is indeed the intersection of NP-hard and NP.

If you can solve any NP-hard problem then you can solve any NP-complete problem (because you can convert any instance of an NP-complete problem to an NP-hard problem), so NP-hard problems are "at least as hard" as NP-complete problems.

(But an NP-hard problem might not be in NP, ie given a purported solution to an NP-hard problem you might not be able to verify it in polynomial time)

Not sure about the pageant part, but it's a major problem when connecting to a compromised server leaks the client's private key.

(For example, if an attacker has compromised server A and you connect to it, they can now use your key to connect to server B which you also use)

The search keyword to learn more is "post-quantum cryptography"

RSA and ECC cryptography could be broken, but (with a probably rocky transition period) we could move to other algorithms which are still secure.

Crytocurrency I'm not sure about.

I suspect probably keeping it secret - announcing it would push everyone to move from crypto you can break to crypto you can't.

I use one to get rid of fixed headers on a page

   javascript:(function()%20{%20var%20s,e,i,ee=document.getElementsByTagName('*');%20for(i=0;%20e=ee[i];%20i++)%20{%20s=getComputedStyle(e);%20if%20(s%20&&%20s.position%20==%20'fixed')%20e.style.position='static';%20}%20})();

Or to put it another way, people waste 10% of their time on the web waiting for slow bloated garbage to load (or more when you take into account pages that do more loading when you touch them afterwards)

For me it's that I want the most inflexible leg of the trip first. I'll often get a local bus to a railway station then get a long distance train. The trains are infrequent and it's cheaper to book a specific train in advance, so if a journey is bus then train I have to get an early bus to ensure that bus delays won't make me miss my train. Whereas going the other way I can step off the train and get whichever bus happens to be next, so train then bus is a shorter journey time.

Browsers won't accept a certificate unless it comes with proof that it was submitted to a CT log.

So a government could MITM you but they'd have to burn a CA to do it, whether you personally noticed the attack or not, so it's a very high cost attack

Bicycle 3 years ago

To expand on one of those things - bike chains get slightly longer as they wear out. Once it's about 1% longer than it started, it looks about the same as it always did, but it's starting to damage the drivechain and you need to replace it. An ancient Roman blacksmith has no hope of making a chain with anything like that level of precision.

Put another way, Turing machines suck even if you enhance them to have 5 parallel tapes (God why do they not have parallel tapes by default, should have at least one for output, one for main memory, one for a stack, and some more as scratchpads)

You answered your question as you asked it. If you juice up your Turing machine like that, it will still suck so much that nobody will actually write programs for it, but it will be more complicated to describe and analyse.

On Windows, when you Copy the program supplying the data decides whether to send the data to the clipboard manager straight away, or whether to defer. If it defers, then yes it does a "last call" on closing. If it crashes you lose the clipboard.

Some programs will ask you when you quit them if you want to keep the clipboard contents, if you'd copied a large amount of data.

Then one of the developers moved house, temporarily misplaced his headset, and we haven’t used it since.

I’m not sure I can justify buying it for my Passport team, even if we were still going through the hassle of pulling on a headset for one meeting a week.

It sounds like he's in the target audience for this VR-for-business stuff he predicts, but he doesn't really want it. If it had been truly a game-changer rather than a gimmick, they wouldn't have abandoned the meetings the moment they had an excuse to, and he wouldn't describe the meetings as "going through the hassle"

To be a proper zero knowledge proof, it mustn't prove to bystanders that Mick knows the secret.

With your simple proposal, everyone watching is convinced. In the more complicated version, only the person calling left/right knows for sure. As far as everyone else knows, Mick doesn't actually know the secret and the reporter colluded with Mick to pre-arrange a sequence of left/right calls.
