>> there is a kind of "spooky action at a distance" that can happen

> This is the bit I can't grasp

OK. Let me give you a collection of statements, each of which I can expand on, but which might give you a sense of the problem.

* Instead of colouring regions in a map we can colour vertices of a graph;

(put a vertex in each region and connect vertices if their regions share a border)

* If a graph can be three-coloured then it can be four-coloured;

(Any three colouring is a four colouring, but with no vertices of the fourth colour)

* An instance of colouring an arbitrary graph can be converted into an instance of colouring a planar graph;

(There is a "widget" that uncrosses edges)

* Given a number to factor, we can construct a graph such that three-colouring the graph will produce a factorisation[0];

(Graph three-colouring is NP-Complete, so this is even easier than that)

Broadly, we can construct a graph that has exactly one (up to permutation of colours) valid three-colouring. As you start to colour it you find that you have to make choices, on average about $4/3$ choices per vertex[1]. But the wrong choice results in not being able to complete the colouring, and you don't know which choice or choices were wrong.

So you get this "spooky action at a distance" thing going on.

Sometimes a planar graph can't be coloured with three colours, and sometimes it can but a colouring is hard to find. When we allow the extra colour it turns out that it's always possible, but it's not obvious that that should be the case.

That's an #ISS-level view of the ideas ... hope it helps.

that's a great point - totally agree on just gettin over the hump of intimidation to try it, and chatgpt makes that hump trivial
Clement and Tribe Predicted the FDA Catastrophe
It's worth it to Telstra, to hold onto the real estate. They have effectively been been gifted a nationwide network of plots of land and structures that turn out to be a good match for 5G/6G/WiFi base station locations.

They are probably kicking themselves for ripping out so many phones in the past, thus giving up the locations.
> then "reading time indicators" (e.g. "5 min read") are added to the top of every story

Many CMSes and static site generators include this and it's genuinely useful (it matters if an article is a short read or something that needs to be saved for later because it requires 30 minutes reading). Is it really "bloat"?
Apparently the swing ratio (as measured by the ride cymbal) used by professional jazz musicians varies with the tempo:

Friberg & Sundström, "Preferred swing ratio in jazz as a function of tempo", SMH-QPSR (1997) http://kth.diva-portal.org/smash/get/diva2:1246291/DATASET01...
Totally! I found ChatGPT to be more helpful in this use case since it outputted full code snippets instead of generating it line by line. The context was also extremely valuable in making iterations (like "make it work for mac")
Interesting, usually the ratio is 2 as it makes triplets!
It has trained on countless programming tutorials out there, including bash tutorials for all kinds of things. Such tutorials often includes "create file -> ls to see file -> print content of file" etc, so GPT then takes those tutorials and creates grammatical rules how those words transform into each other. But if you start going outside of the realms of online tutorials it starts to falter quickly and then just prints nonsense.
Correct me if I'm wrong, but no one is stopping you from making multiple accounts on various instances to overcome this built-in "limitation"...

Also just run your own instance?
The example was for compile-time known sizes.
This is looking really hard for a problem that isn't there.

Has the author actually used Mastodon? I wonder what server they ended up on to have this impression. And I find the claim that people don't want to run generalist instances... interesting. I ran a few of these and while they all had a theme and a few cultural baselines (which is okay, other instances have other standards), none of them really restricted what you post about.
I suspect that is a headliner "syntax" feature for many more serious Nim users. Initialization, like error handling, is one of those things that is easy to mess up.
This is a highly ideological opinion piece written by someone who fails to acknowledge many inconvenient facts, including: the federal government pays these "entitlements" (really, upcoming obligations) every year; annual federal government deficits, i.e., after paying all such obligations, have averaged ~3% of GDP for a long time, so the government's ability to pay such obligations has grown with the size of the economy; this is despite federal income tax collections and marginal tax rates being at or near their lowest levels since their peaks during the 1940's and 1950's (!!!); and finally, governments cannot have a surplus unless the private sector in the aggregate has a deficit of exactly the same magnitude over the same period (adjusted for net exports, which are immaterial in comparison). I wonder if the author even understands NIPA tables and their accounting identities.
Ah, that makes so much more sense. I had thought after looking at the wallet: https://www.blockchain.com/btc/address/bc1qd2jkf8lxp5d3y50gf... that it was "scrambled/tumbled/anonymized" by the attacker.

100%, also just looking up dev docs for frameworks. Something like "write a post API in Golang's Gin framework" instead of looking up what that syntax was again
Some counterpoints: 2 mathematicians greatly increases chances of senility. Blogs/twitter also correlate much stronger with author age than truth of statement.

>The argument looks like it's based on large n asymptotics, so even assuming everything works correctly the strongest statement they can hope to show is that the theorem is true for all n > n_0, where n_0 is some large constant. But there is no mention of this fact. The theorem is claimed for all n.

This is completely wrong. A proof for all n>n_0 is a proof for all n, since any counter-examples have to exist as subgraphs of arbitrarily large graphs.
There's no substitute for decades of having programmers giving you (and shouting at you) blunt feedback on your programming language proposals.
But they are trigametic and not bigametic.
That looks sweet. I wonder if anyone is importing those, or if Panasonic has any plans for a U.S. version.
Famous photos and the cameras they were shot on
I also agree with the OP. My personal take on the experience so far:

Joining a server feels like I'm hanging out in someone else's backyard. There's this feeling that at any point I could be asked to leave if I overstay my welcome. The server I'm attached to is run by someone who seems very friendly and so far I'm enjoying the community they're trying to build. However, I am struggling to wrap my head around this weird intersection of public broadcast over a semi-public (someone's backyard) space.

Unlike Reddit or Discord where I can partake in multiple forums through my single account, my entire public persona on Mastodon is tied to the server I'm on. It really limits what I want to share as I don't feel as free to talk openly about any topic.
Your analogy is inapt; the whole reason dark matter is hypothesized is precisely because of the directly observable, inarguable effects it has; we can even see that it is both not evenly distributed and not distributed congruently with matter, so we know enough of its nature to give a name to the phenomenon.

Regardless, you've misunderstood my point, which is that if you expect religious phenomena to be undetectable (not "we haven't observed it" but "you can never observe it") and ineffectual (not "we haven't observed its effect" but "you can never observe any effect") then it simply isn't real in any useful sense: religious, scientific, or otherwise.

And I don't think religious people believe that: I think they think their religion is real, in that it has effects (a volcano doesn't erupt because we've made appropriate sacrifices to it; my consciousness will live on in some way in the presence of other personhoods after my death, in another place; Florida will be hit by more frequent natural disasters because schoolteachers tell students that gay people exist) and is observable (my charismatic evangelical preacher speaks meaningful sentences in a foreign language when possessed by a spirit; unhappy dead emerge from the ground each year to be led by Hecate against the living).

I'm pointing out that while, as a conciliation (essentially, because people dislike it so much and grow antagonistic and violent when challenged), we often say that religion and science are separate, or that religion, as something that is taken as faith, is not investigable by scientific methods; in fact if religion has any reality or meaning then it is investigable. Not necessarily as a practical matter (though to some extent, it is practicable), but there's no principle that precludes any religious hypothesis from being tested.

To boil it down: if a religion were real, we could test it. An assertion that it's untestable is equivalent to saying that it's purely imaginary. That's different from saying that we just can't test it yet.
If user replaceable batteries are so much worse, which makes sense, we need to force companies and customers to return their devices once they're done with them. That it makes one each cycle worse doesn't matter if it makes it so the materials only have a single cycle.
Probably mistaking Denmark for "Holland".
2.5 is sort of the over-the-top classic laid-back sound. 1.25 also works very well and is typically close to what you hear on faster passages in a lot of jazz. It would be cool if this had multiple sections of music to show where different swing ratios are appropriate, like some faster and slower stuff, Bebop and other styles.
yeah, like speech played in reverse - satanic!
Rant warning.

As someone who made great sacrifices, to pay off my loans immediately after graduation. I could not be more vexxed at the current administrations policy on this, over any policy executed with executive authority in my life time. I fully paid off my loans just before covid started.

I received pell grants, I worked full time while in school. I drove, maintained a 15 year old car, and live with roomates.

Additionally the amount of sound clips and articles, I hear because of this policy in America calling for more relieve. Makes me far more conservative than I would have ever been.

I also left out a rant on the deficit the US has.
No, it does. I'm saying asking someone where they're from yeilds no facts about that person if all you get back is a name of the country. It doesn't mean they definitely grew up there, or that they hold citizenship. But it's easy to just take the name of the country and assume a bunch of things about the person based on things you heard about people from there. There may be statistical probabilities there but no certainty. People have done it since forever and it's essentially the same mechanism as OP described.
Yep, that's the reason! The ingenious idea of using quantum amplitude modulation unfortunately also meant that slight phase shifts--which happen easily in broadcast TV--appear as color errors.

PAL fixed it by flipping the phase around every line. By subtracting the current line from the previous line, the phase error would cancel out (but is also more expensive since you need to remember the last line, in a delay line or memory[1]). So, always the same color. (But not ATSC, that's something else entirely...)

[1] Well, there wer supposedly "PAL simple" receivers in the very beginning, where no processing of the phase flip was done and your eye was supposed to average the difference out. Probably looked terrible unless you were sitting really far away...

> How does this JamiID work?

If you register a username for your Jami account, your JamiID will be that username, otherwise it will just be the account's infohash (public key fingerprint). A Jami username is a mapping between a unique human-friendly name and an account infohash.

> Is this JamiID that I created forever mine?

With the default Jami name server, https://ns.jami.net, username registrations are permanent, and cannot be changed or deleted. Also, if you delete or lose your account without having backed it up earlier, you will lose that username and it cannot be recovered. This is one of the reasons why it's really important to back up your account.

> If my friends create their JamiID, will the search just list them?

Yes, you can search others by their JamiID, whether it's their username or the longer account infohash.

> Do I need to import any JamiID's? How does discovery work for these JamiID's?

You would search for their JamiID and add them as contacts, similarly to how you would with other messaging applications. When you search a username, Jami will query the name server to get the account infohash and send a contact request. For example, with the default name server, to look up 'bandali' Jami would make a request to https://ns.jami.net/name/bandali to get the associated account infohash.

You can read more about this on the Jami user FAQ and the 'name server protocol' section of the developer manual:

https://docs.jami.net/user/faq.html#how-does-the-username-re...

https://docs.jami.net/developer/name-server-protocol.html

> I'm seriously looking into Jami for "conference" calls with a small set of family members, it should be just point and click.

Pretty much. :) Jami should be able to fit that use-case nicely.
I do find it curious that the only neighbourhoods in my own city where use of bikes for that sort of thing (grocery shopping, taking kids to school etc.) is common are typically fairly well-off ones.
I'm wondering if part of the reason is that those in poorer neighbourhoods are too worried about having a bike stolen? (it would certainly worry me!). Obviously part of it is also lack of investment in decent bike-friendly infrastructure. But I suspect it may be partly cultural - esp. in areas where there's a significant number of recent immigrants who might think of bicycles as something people would only use to get around on in the poorer countries they came from.
Woaa horror story, what a luck that you didn’t get hurt!

Anyway it’s weird because it doesn’t look broken on a weld, very rare situation, titanium should last forever.
I find it interesting how much harder it is to grok bash/sh/zsh than other languages I’ve learned. Off the top of my head it may be tooling like the lack of linting, or maybe it’s just experience as I avoid complexity like the plague when writing bash which sounds like a self fulfilling feedback loop.

Gpt does seem to unblock this mental burden a bit which has me excited for its potential when it comes to education/teaching.
Fun idea, but why did they travel in different directions for each test? The environment and line of sight are everything in this type of testing, so it doesn't make sense to wander in different random directions and then try to compare numbers.

For the final test they went up in elevation and had what appears to be line of sight back to the base station. That alone was probably more impactful than any antenna change.
Great question, have enjoyed reading answers. For me, a clipboard manager has easily saved me 100+ hours of work time (I use CLCL and Clipy). A close second was upgrading my hardware - image editing which previously took minutes on my 2014-era machine now takes seconds.

>I didn’t see the comparison because it didn’t make sense to me. YMMV.

The comparison was between the compexity level. Also between MIDI and MIDI 2.0: whether 2.0 would be similar to its current serial MIDI 1.0 implementation, USB, or BT complexity wise.

>For me, Bluetooth works much better than MIDI because there’s no setting channels or sending all-notes-off because something hung up.

That must be a joke, right? Because BT is 10 times worse in this regard, getting the user to manually forcefully do a connect/reconnect cycle, not connecting and not knowing why, dropping the connection, and so on.

MIDI once it's connected, it pretty much just works: which is why they do live shows with midi for 3+ decades, whereas they wouldn't touch BT for live show with a 100000000 long pole, even if latency wasn't an issue...

Panda has taught me a lot.

Just before it hit, I had a small site that was on the rise in terms of traffic. A hobbyist site, no ads, all original content, and very much not "thin". An enthusiast site, much like the original internet. Incoming links were organic and spontaneous, from serious sites.

Panda crushed it. Massive pagerank downgrade and traffic decimated to about 5%. In mere hours. A false positive, I suppose. I spent 3 months trying to figure out the reason but nobody, including Google or SEO specialists were able to provide any tangible answer.

That day etched a few important lessons into my long term memory:

1) The size of Google's power. It effectively has the power to decide whether you digitally exist or not. The ultimate traffic controller.

2) Even a good faith move by Google may have 1% of false positives. Which seems totally rational until you realize that at Google's scale this could mean millions of people being totally fucked out of the blue.

3) Worse, when that happens, there's no accountability. You can't go anywhere for help, undo being a false positive, you're just randomly fucked and that's it. You cannot depend on anything ran by Google.

Although I'm fine and it wasn't exactly a pivotal moment in my life, it radically changed my view on Google. Early on, I was a fanboy. Google kicking lame Microsoft's butt with miraculous products like search, maps, gmail. I was cheering them on. As of my "lesson", I've grown increasingly cynical.

That was 10 years ago. They've become infinitely worse.
This is a great example of how someone with little programming knowledge could leverage an AI into building simple scripts.

Lately I've been encouraging my friends into trying just that.

If the poster would want, for example, to save all current tabs when switching context (going from dev to marketing, for example), this would quickly turn into a more involved debugging/prompting question.
IMO Mastodon will settle like email has. A handful of mega servers and a smaller group of people who run their own for their use only.

Owners of medium sized servers will tire of the maintenance and moderation.
Sure, but you also learn from experience. If it turns out dust on panels is usually the limiting factor, and the rover otherwise stay in good shape well beyond expectations, a mitigation for the dust may be an effective solution in reliably operation lifetime and thus mission scope.
I love Jitsi Meet. My friends and I started using it during COVID and it's constantly improved. I host my own instance using docker and it's a breeze.

Enforcement and prosecutorial discretion are ideally the exception rather than the rule, I think. Principally because discretionary enforcement is too often abused as selective enforcement. Structurally (systemically?), I don't think it's good to have laws on the books that, with a wink and a nod, nobody "really" believes.

But to my original point - none of this critique comes from hate or ignorance.
So, one fuckup, and you can’t fly anywhere, with any airline, for the rest of your life?

Check out Stevenage in the UK. It ain't no paradise.

It has what appears to be identical segregated cycleways and has done for 60+ years now ( https://www.roadswerenotbuiltforcars.com/wp-content/uploads/... ), yet cycle usage is less than 3% despite the town being literally designed around and built with cycleways from day 1. https://en.m.wikipedia.org/wiki/Stevenage

Minorities aren’t a monolith or fungible. The fact that Harvard hires some minorities doesn’t change the fact that those minorities were hand picked by white elites and operate within an institution dominated by elite whites.

Now, that doesn’t mean those minorities can’t be great professors, as individuals. But it does mean that their views on minority issues shouldn’t be give any more weight than those of the elite whites that selected them and on whom they depend for their position and status. Leadership on those issues must instead come from people who are put in positions of leadership by minority groups themselves.
Bash isn't that bad... except there are 20 ways to do anything and 18 of them are wrong, but only 1% of online examples will use either of the two correct approaches and simply reading docs won't always clue you in about how the technique or syntax it's describing is actually subtly wrong and you should ~never use it.
There's always going to be a programming layer, at least until AIs can self-improve, and at that point it's basically AGI. In other words, programmers will be needed until the "singularity" and then we have no idea what happens.
The thing about bikes is that if you want to go fast, you have to put in kilometers on the saddle. That trains not just your body, but also your mind, and teaches you how to behave on the road. An electric bike allows someone with little training to go much faster than they would be able to otherwise. Now imagine that you're an experienced rider going at a cool 35 km/h and as you're about to pass a newbie on an electric bike they swerve into you because they don't yet have the habit of looking back before moving sideways. Yes, it's a mistake of that particular person alone, but it's a mistake they were able to make because e-bikes exist.
