You may want to take a look how Bitrix24 approaches helpdesk, even though they are free - https://www.bitrix24.com/tools/contact_center/ . The idea behind Front or Helpwise (and it looks like you are inspired by them) is that the biggest problem is routing requests between different people and collecting requests from all available channels in one place. The idea behind Bitrix24 is that 'single inbox' and 'multichannel' is just the beginning. Your helpdesk has to be a part of your communication and marketing machine. Intercom.io is having a similar approach. I believe it's more promising.
Developer guide to get on board with a chaos engineering project
MWI doesn't explain much. Why should this electron be able to cross universes and talk to another one and interfere, while nothing else can cross universes?

Can I setup my experiment so that quantum decay decides if I emit an electron or not - and then wait for no electron, but I somehow detect the electron that was released in a another universe?

MWI also doesn't explain why the individual electrons would take different paths and interfere with each other - the universes are identical, so why are the electrons taking different paths?

> enumerating derived classes at compile-time is usually a bad design
did you deliberately omit the word 'exhaustively' here ?

late-bound != dynamically typed, that's exactly the point - you wish to preserve to the ability to have types loaded at run time without knowing their exact type at compile time while still enjoying strong type guarantees. We can do without run-time loading scenarios at all and still see why this is bad, if one adds a derived class to the code base and then has to address it in a bunch of places rather than have all the new functionality localized to the class then it's a smell
This seems more like job training than education - something that should be directly done by the companies that end up recruiting these people instead.

You may be missing that most martial arts people practice are for exercise and social display, not for self-defense or killing.

If it has katas/forms, if certain moves are proscribed during sparring, or if your teachers have not told you the catch-22 about there being no morally acceptable way to practice genuine kill shots even though they're all that really matters, then you are not preparing for self-defense in a life-and-death struggle.

So, martial arts may be the appropriate metaphor.

Particles don't really exist. Nor do waves for that matter either. Generally these days, it's considered more correct to think in terms of fields and excitations. Even then though it's important to realize that what we're working with are models. Very powerful and extremely accurate models, but still models nonetheless at the end of the day.
Place a detector in front of the slits. Only a single particle in a single slit is detected. There is no "splitting" of the particle that we can see.

Edit: If you try to actually define "wave function collapse" and "observer" you are back into the same mumbo-jumbo as "wave-particle duality". They are just placeholders that obscure the mystery.
Email+PGP may have some usability flaws, but it far surpasses the security of Signal against powerful adversaries, especially concerning metadata.

Why can't a particle induce a wavelike field that interacts with slots and itself?
I did some back-of-the-envelope numbers on the one I came into contact with previously (also keep in mind this was 6 years ago now too!):

20-30x students per cohort who paid ~$20K upfront for a 12 week program.
20% signing fee (based on 1st year comp) from employer on placement.

We definitely were not paying top of market as some of these students ended up at Uber and Facebook. That said the all in 1st year cost between base + signing bonus + equity wasn't much short of $200K. So:

30 * $20K + 28 * $200K * 20% = $1.72M/cohort

As for outgoings, all of the mentors were volunteers. As were most of the instructors. The content is mostly a one-time sunk cost to produce and is redelivered across cohorts. The largest overhead would have been a building lease. The biggest constraint on growth is how large you can make a cohort or how many cohorts you run (either multiple per year, or opening new locations).

Really felt like a bit of a racket that had found what was almost an arbitrage: between the inability of Bay Area companies to find local talent, the huge costs and risk associated trying to relocate people via H1B, and the desire for people to re-skill at any cost because tech jobs/salaries were distorting everything else in their city.

Sure it's not a $1B outcome. It's a pretty profitable and repeatable business, and especially given the limited downside risk (mostly carried by the students, who've already paid).
Compression Streams – JavaScript APIs to compress and decompress binary data
I can't follow this analogy. Claiming that Efail showed weakness on the part of PGP is like claiming that cryptosystems should be designed not to release unauthenticated plaintext to callers, and that the "authenticated/unauthenticated" status of a message shouldn't be communicated out of band. You know, like how all modern AEAD cryptography works.
Totally get your friend's concern. Google is kinda bad in that they bundle a bunch of permissions into one (i.e. - all data read and changed...etc); we only need a small subset of that, and we have a very strict privacy policy not seen in other extensions, but users usually don't dig into our policy and get scared by that dialogue (which is totally understandable and I would be too).
I mean, you probably shouldn't rely on the local system time for determining lease timeouts for correctness, if it matters.
Are you able to cite your source for this? The UK transposed GDPR into its domestic legislation so this shouldn't be possible at the moment.
You don't. The same way that you don't ensure your recipient doesn't leak screenshots of signal conversations to icloud.
If you place a detector in front of (or behind!) the slits the wave function collapses and there is no interference pattern. This is all part of the mystery of it, as soon as you 'observe' a particle, in any way, it stops acting like a wave. See the Delayed Choice Quantum Eraser experiment for even more weirdness, a good video on it: https://www.youtube.com/watch?v=8ORLN_KwAgs
> Y Combinator invest $150K in startups for a 7% slice of equity, by comparison, a $20K investment from Pioneer will cost founders 5% of their company plus the 1% they gave up to join the accelerator in the first place.

The 1% for advice, status, etc. sounds like a good deal. $20k for 5% though sounds really steep unless you're planning on a very low exit (under $1M).
The wave a boat makes can certainly travel through two arches in a bridge.
An alternative signal client could forward all messages to a gmail account (pt 1 from my original post) and store the messages in plain text on the local computer (point 2).

Of course these would be very poor design choices for the alternative client, but none-the-less technically possible.
We studied a lot of detailed semiconductor physics in my engineering degree. Certainly loads of details were left out, but knowing something is possible and roughly along which lines it could be achieved is a huge hurdle in the innovation process.

> Why would I bang my head on obscure stuff if my next meal or a decent living is assured to me ?

What sort of view is this?

We know that many people do exactly that.

Darwin was a self-funded "gentleman scientist", as were many other scientists of his era. (See https://en.wikipedia.org/wiki/Independent_scientist.) Why did Darwin work on obscure stuff like insect pollination when a decent living was assured to him?

Why does Elon Musk work on "obscure stuff" like rocket science, when he has no need to work for the rest of his entire life?

On less grandiose levels, I know people who would spend their time doing FOSS if they had a basic income, instead of making a living developing commercial proprietary software.

We also know some lottery winners will continue to work - because most people like to be engaged in productive activities.

> Because science fiction is the opposite of history, it is a wild painting of the future. And you find that human race wherever they are, whether they are confined to this tiny planet or spread across the Milky way in the future, they never change.

I don't think that's the right view of SF. SF authors rarely paint about the future. They paint about the present day in a different and often futuristic context. And they write for what their readership knows.

Asimov's future humans are mid-20th century Americans ... in space.

But even then, Asimov's humans do change. The Earth culture of the Caves of Steel are different than the Spacer culture.

As an even more direct counter-example, the Gaia project in Foundation and Earth is a deliberate attempt to make a different type of human. From https://asimov.fandom.com/wiki/Gaia "the human beings on Gaia, under robotic guidance, not only evolved their ability to form an ongoing group consciousness, but also extended this consciousness to the fauna and flora of the planet itself, even including inanimate matter. As a result the entire planet became a super-organism."

If that's not change, I don't know what is.
You need a certain amount of karma before it is enabled. I can downvote comments - but not posts. I've got just over 500 karma. I think 500 was the tipping point.
> cross universes?

MWI is a local theory. Changes spread out at the speed of light, they just spread out (and back from) adjacent universes as well. https://www.hedweb.com/manworld.htm#local

> the universes are identical...

Think of a 3D volume of space with a plane wave travelling through it, such as a beam of coherent laser light. An alternative way of thinking about this is that each point emits a spherical wave and the plane wave is just constructive interference of a continuum of spherical waves.

In many worlds theories, you can think of each point as also spreading out into non-spatial dimensions that are directions towards other universes. Similarly, aggregate behaviour is the constructive interference of not just the points in "one" universe, but also the points in a neighbouring "volume" of universes.

If the neighbouring universes are identical, or nearly so, it's like the coherent laser scenario. If they're all different, it's more like white light -- it's unpredictable and "random", but otherwise it's still just ordinary light.

Very slight deviations would result in various interference effects, such as the double-slit scenario.
UTM: QEMU for iOS
Earlier this week I had an idle thought around the measurement problem, did some searching when I came home and stumbled over this[1] paper where they show that the degree of "waveiness" V and degree of "particleness" P of a particle is related to the degree of self-entanglement C:

V^2 + P^2 + C^2 = 1

They've since done a follow-up experiment[2] to demonstrate it in a quantum setup as well (first paper did classical experiment).

I'm just a layman so have no idea how profound this is, but I found it interesting.

These are not interesting points. Respectfully: do you have interesting points about what an alternate Signal client might actually do?
Yes. I think it has the same problem as IndieHackers (which stripe also invested in / acquired), where it’s mostly for people who don’t have anything going for them. If you already know what you need to do it’s a waste of your attention. It’s becomes social media for founders.

And anything social will promote what is popular or trendy to the tribe, and some of the actual better businesses are neglected because they aren’t “interesting”.

This brings the quality of the whole experience down since the best contributors are absent because they are building a company.

i personally would rather just get funding and take advantage of investor connections via introductions, and maybe occasional strategy advice. I don’t want the extra work. I currently have a side business making over 70k/mo in revenue and don’t have time to do anything extra. (Yes, side project, not solo)

I don't really care so much, as long as it can be used with IRC, and the web page should specify which IRC server to use that is readable even if JavaScript and CSS are disabled, and even if the request headers have unusual values.

I actually use PGP. Your comment complexly glosses over the “email” part. It’s “easy” to send an smtp email over tor without giving up too much info via side channels. (It’s impossible to get the message you sent to reach the inbox, though.)

But to reliably anonymously receive emails is a different story. It’s really hard for the average person to get a persistent online email address without a phone number, without going through google, without paying with a credit card, without being tracked back by your provider, etc etc.

It’s not very different from Signal in that regard.
Sorry! When merging threads, we always try to exempt the comments that only make sense in the original context. I even saw your comment and recognized it as such but it must have slipped through my fingers somehow. We've repatriated it now. (Of course now these replies are out of context, but oh well.)

It’s not latency, it’s throughput. Broadcast and incast network communication patterns in the LAN kill throughput, and are present in any quorum protocol. Atomic broadcast protocols like chain replication or LCR which use strictly sequential communication patterns (via chain or ring topologies) have much better throughput in LAN environments than Paxos/Raft (except for Ring Paxos, which requires IP multicast). In addition, because they outsource group membership and failure detection to a separate (likely Paxos-based) service, they require only f+1 members to tolerate f faults, rather than 2f+1 (see Lamport et al’s Vertical Paxos work). But they have two main downsides relative to Paxos/Raft-like protocols: latency grows linearly with cluster size and is bounded below by the slowest node (so they aren’t a good fit for high-latency WANs), and as noted above, they can’t “self-host” like Paxos/Raft.

PS Apparently my previous comment outraged the HN hive mind, judging by downvotes. I find this hilarious and revealing given that all I’ve said is obvious to any actual distsys researcher (ask eg the HyperDex or FawnKV folks about why they chose CR instead of Paxos). And at one large cloud provider I worked at, this was taken for granted back in 2012. Apparently “distsys” pop culture has yet to catch up.
And I should seriously implement the Signal protocol on decades old equipment in the middle of a company infrastructure that's on an intra-net, when I can hack something perfectly serviceable instead. Well... I mean... Yes, I should :-) But it's just not reasonable that I'm going to get that budget.

Not every application is your application. Not every fight is your fight. If you absolutely must insult someone, target it and be specific. But, better yet, get your message across without insulting people. It will be much, much better.

Chocolate cookies take sugar. Sugar is white, therefore chocolate cookies are white.
That was my idle thought btw (mentioned in another comment), that this "either it's here or it's there" sounds a lot like the way two entangled particles behave in a Bell test. If Alice measures up, Bob measures down... if the particle does through the left slit, it's not going through the right slit.

So my thought was maybe the particle in the two-slit experiment was entangled with itself? Like I said, idle thoughts of a layman so not sure how right, wrong or not-even-wrong this is but hey, always fun to think about QM :)
I reject the idea that people should seriously consider the shoddy security of encrypted emails so that your "decades old equipment in the middle of a company infrastructure that's on an intra-net" can participate on equal terms with commodity phones that are 2x as capable. That's the quintessential argument for ergonomics over security, and that's the offensive argument, not mine.
