The Erdős–Hajnal conjecture says that for any graph `H`, then every graph in the set of graphs `F_H` that does not contain `H` as an induced subgraph will either have a polynomial amount of cliques or a polymomial amount of independent sets. The growth rate of the exponent depends on the size of each graph in `F_H` and on some properties `H`.

Like with most simple questions in Ramsay theory no proof or contradiction has been found for the general conjecture, but there has been some progress for some `H`.

The latest paper proves that the conjecture is true if `H` is a cycle of 5 graphs. Since proving this was so hard and provided so much insight, there's hope that the general conjecture can be proved without a lot more work.

Here's an actual ELI5:

There's a party where some pairs of guests know each other and some don't. A genie told you that there isn't any group of 5 people that only know two people from that group in a way that those relationships form a loop (1 — 2 — 3 — 4 — 5 — 1).

Knowing that, you reason that this cannot be a regular party. Instead, it has to be one of these two:

⒈ A class reunion, where there's a large group of people that all know each other.

⒉ A group blind date, where there's a large group of people where nobody knows anyone.

Being a smart 5-year-old the genie pushes you to publish a 19-page paper proving this, but you find out in Hacker News that some academics beat you and published it this February.
> When you swap out somebody who does a decent job for another person who performs at about the same level it's not really that noticeable.

>> Which interestingly is the same effect as swapping out somebody who does nothing for someone else who does nothing.

I disagree. Swapping out a decent senior dev for a decent senior dev doesn't have a net negative effect like swapping out a senior dev who does nothing for another senior dev who does nothing. In scenario one, you have a senior dev who ramps up in a decent amount of time, does the work they're paid for, and isn't a waste of time and money like a bad hire. In the second scenario, you have a senior dev who's just as damaging as their predecessor, but you've lost the time and money you've invested in onboarding them while also paying the ongoing opportunity cost you could have avoided with a decent hire and any technical debt they accrue gets tossed on the pile with the rest of the debt their predecessor accrued. It would have been better to have just kept the first guy instead of wasting time, money, and morale on someone new.
If otherwise young, healthy ppl were dropping dead in droves because of this, then I think there would have been more more mobilization, cooperation, and compliance, but the later data showed Covid only being slightly more deadly than the flu for young and middle-aged people instead of 40x as deadly as originally feared.So the urgency and concern began to dissipate by mid-2020 when the studies came about affirming a much lower IFR than originally feared. Second, many of these European counties, which early on seemed to have contained the virus owing to superior policy decisions and praised by the media while Trump was heavily criticized, had major second, third and even forth wages by late 2020 and 2021. This show the difficulty of ascribing blame either way due to the inherent unpredictability and virulence of Covid.
No, I don't share that view. I think cryptocurrencies seem, at most, equal to conventional evasive techniques, maybe even less useful when factoring in the hoops and overhead in actually translating the funds into real world goods and services.

It's also unknown what the future holds in regard to effective tracing capabilities, retroactively, by law enforcement and agencies.

My view is based on crypto and society ‘as is’ today. I would have to imagine a different society, with a radical adoption of crypto, to support your argument. But I would if that was the case.

As I'm not American, this whole cheerleading thing feels very weird to me. It's weird to see the role of boys to play sports while the girls cheer doing elaborate choreographies.

I doubt weeds will be able to maintain advantages that let them compete well to begin with, while also evolving to evade all of a series of detection techniques that will be added as they evolve their way around the first few. To stick around they need to survive well outside of fields, too, and I'd expect detection-resistant varieties to become increasingly inefficient at surviving in areas where they're not being lasered to death.
On the one hand:

> The coaches said Levy’s snap violated the team rules she had agreed to, including showing respect, avoiding “foul language and inappropriate gestures,” and a strict policy against “any negative information regarding cheerleading, cheerleaders, or coaches placed on the Internet.”

On the other hand:

> Some cheerleaders complained about Levy’s message, and the coaches decided to suspend her from the squad for a year.

This entire thing could've been avoided with a reasonable response. Like a reminder about the team rules. Maybe a one week suspension. A full year suspension is insane.

That said, she obviously had no choice but to agree to the rules, so that's no defense against a First Amendment violation.
I am incredibly glad someone not-me is wrapping OpenCASCADE. It's an incredibly powerful tool, but it's also kind of a beast of an ancient C++ library with all of the trappings that comes with, like its own version of smart pointers and years of accumulated presumably-unused cruft.

Yes, that's correct. Also, separately, Google is sunsetting the "Google Play Movies & TV app" and folding that into the YouTube (not YouTubeTV) app.
Perhaps not much now but a use for them might come along and it will be good that this will be there ready to fill the need. It's my understanding that quaternions were mostly a curiosity when first described in the mid 1800s but now are used extensively in computing. From wikipedia "quaternions are used in computer graphics, computer vision, robotics, control theory, signal processing, attitude control, physics, bioinformatics, molecular dynamics, computer simulations, and orbital mechanics." When Sir William Rowan Hamilton first described them, he had no concept of most of the above, much less that quaternions would be important for them. Good for us that he still pushed forward with them.

Private tv channels are constantly under attack.
I like sequence diagrams and state diagrams (well just straight finite state automata). They bring an extra layer of description that is otherwise very hard to extract from the code.

I draw them with Plantuml. Text input is really a must have for me. On crowded diagrams it may be difficult to fine-tune the layout though.

I still sometimes do class diagrams, although I do not find they carry much info compared to the code. The meaning of arrows is ambiguous and they're too verbose. APIs are better documented with e.g. Doxygen.
Exactly. Isn't that the whole point of free-speech?

Still they could sell foundry services for any spare capacity, or sell them to another company when it's no longer using them for cutting edge. I'm sure there's a very good reason they're not going that route but I can't help but think the whole world would be better off if the players that can afford it would operate their own fabs.

I guess as long as Apple thinks they can remain the highest bidder at TSMC and China doesn't invade there is no reason to think their supply is threatened.

I ended up with "site:bbc.com" and "site:svt.se" to get to actual news instead of click-baits. Why the search function of these sites is crap, to the point where it's easier to hack Google, is beyond me.
Oh yeah, I saw some documentary about bitcoin in Africa. It was so sad. This woman standing in basically a muddy hut, stirring some soup, and saying how she put everything into bitcoin because they say it always goes up. She had no idea what it is.

Someone basically tricked her into buying lottery tickets. (who knows, maybe it'll work out just fine)

That's not even close to "using bitcoin". To a rounding error nobody is actually using bitcoin (even less the other cryptocurrencies, since it's even more rare to be able to), except to commit crimes.
I have a strong emotional connection with Slackware. I downloaded everything except X11 via my family's 2400 baud modem in the early 1990s. I was amazed to have Emacs and the GNU compilers on my own laptop. 6months later I bought all of Slackware on about fifty 3 1/2 inch floppy disks and I was in heaven.

At the same time at work, I was building systems on top of SCO Unix, which was good enough but expensive.
"Placed on the internet" is imprecise but my interpretation would be "posted in public on the internet/web". If Snapchat is equivalent to "placed on the internet" presumably so would be simply saying something to someone 1-on-1 in a voice-over-IP phone call.

Can a public school make participation in extracurriculars (often key to future college applications and thus your life/employment prospects) contingent on never even in a private context criticizing the school's management of said activities? That strikes me as an extremely expansive power open to all sorts of abuse, and almost certainly unconstitutional.
He's clearly suggesting making context aware search an option.

The narrow tunnel-gage of Boring Company is designed for cars... presumably it'd be possible to have a train vehicle with a form-factor more like stretch minivan than a bus. Lots of moving parts because many many more doors to open-close than a traditional bus or subway. But still, if stop-to-stop times are under half an hour, is it okay to seal someone in stretch-minivan-like train car without a bathroom for half an hour? I dunno.

It does mean that non-stop from LA to San Jose would be right out though. Being conservative and assuming a 300km/h vehicle, you'd want at least 3 stops along the way if people are completely trapped in the vehicle without even being able to stand up, much less relieve themselves.
That's not really an investment. Sounds more like retail hiring.
I wasn't going by market share but by pricing. MBB charges the most per amount of "value" /"intangibles" delivered.
One is criticism of the running and operation of an organisation; the other is steeped in the history of genocide and slavery, there are even laws in place around the world to protect people from it because of it's heinousness. But you're professing that advocacy of racism is no more malignant than basic complaints about a company?

I'm not sure if what you're advocating is because of perhaps missing education on the subject but this is a serious hot button issue at the moment; I'm honestly surprised you'd espouse this so freely.

>prices of goods, materials and labor decreased, although at a low rate of less than 2% annually

you can deal with. Crypto style 50% drop in months type deflation would make debts in that currency unpayable.
Having used a 3270 terminal in an extremely saturated system, it's amazing how much your way of working changes. Typing a full page of code, checking for typos, doing a test run in your head, then finally pressing Enter and sipping your coffee while the system took 1-2 minutes to process the screen.

As soon as it was upgraded, we reverted to the normal workflow of pressing Enter first, the correcting typos, paginating instead of searching, debugging live instead of in our heads, etc. I don't think we were more of less productive either way, they're just different ways of working.

I don't think my, or any, national currency is secure forever, but neither is any cryptocurrency. Currently national currencies are, on average, far more stable and secure places to hold assets than any cryptocurrency.

If your national isn't as stable as you like, you can more easily use a different national currency. If your country has capital controls that prohibit this, then you are using cryptocurrency to break the law.

My contention is that so far the only use cases cryptocurrency has been successful in are illegal. If the legal restrictions in those areas were removed, cryptocurrency would no longer be useful there.
Although to be exact I would not even call this any "mistake". It is simply human. But I do understand that others might consider it to be so.

Here's what our digitization expert, George Blood, has to say: LPs are soft and played with a very small diamond. 78s are made from shellac which is hard and abrasive. Originally they were played with steel needles at 10x the tracking weight used by our modern equipment. They also use a much larger diamond with 5-10x the surface area. The tracking force is spread over a larger area than vinyl playback. The contact pressure is less than 10% of vinyl playback.
They've never taken out a settlement the size of a city but there have been a couple of tailings dam collapses in recent years that have led to the deaths of (in one case) 270 people and (in the other) displacements of hundreds of people, along with widespread downstream pollution:

Brex definitely has first mover advantage, but I question the moat with Fed Instant Payments coming around the bend in 2023 [1]. Other institutions (especially Chase based on Dimon's latest shareholder letter [2]) are aware of the existential threat fintechs pose to commercial banking institutions, and so it becomes similar to Netflix's effort to become HBO before HBO could become Netflix (if the intent is to become the go-to institution for business banking and treasury management). There is an incredible inertia in non-startup finance departments (from the CFO down), but perhaps Brex can overcome this inertia with their financial OS offerings if legacy banking can't get onboard with becoming engineering/technology first institutions (institutions who will face pressure to offer more value due to payment fee compression/revenue destruction and already low deposit interest income).

Exciting times ahead in fintech regardless of who wins.

I think its perfectly fine to shun people if you think they're awful. Continuing association with someone who is, for example, is supportive of ethnic cleansing, is expressing that you condone those things. Choosing not to decide is still a choice.

The question at hand is whether you believe isolated private communications to be representative of true nature.

I find this statement strange. Curious if others experience aligns with mine:

Being a CEO is all consuming.

You don’t want to be a parent and a CEO, cause the company comes first.

You don’t want to be married and a CEO, because the company comes first.

If you could “automate” this job, the developers behind the scripts become de facto CEO. Their scripts cannot fail. They will have to make the same sacrifices as the meatspace CEO.

I dunno if it’s an Icarus thing or what, but the closer I am in interactions with ceos, the more I pity them.

Asking these people to trade their lives for the possibility of no payout seems doomed to fail. The only reason people trade their lives for this role is because it is worth the personal damage and risk.
No it isn’t. If you have Google maps open and suddenly decide you want to go to McDonald’s, then sure, that voice command should go to Google Maps. But if you make a voice command to send an email to someone, it shouldn’t open Gmail instead of your default mail app just because Google maps is open.

Similarly, if you’re watching a video on YouTube and want to search for a cat video, sure, the voice command should search in YouTube. But if you want to listen to music and have Spotify set as your default music app, it shouldn’t send the request to YouTube Music just because YouTube is open.
OK, that makes more sense. However, your comment does not take into consideration the benefits from cars, which should be considered to accurately assess their overall effect on quality of life.
This is a city where police do not care if your bike is stolen. A complaint about a bike lane violation that might clear up 15 minutes after I call won't carry much water. The cops parking in the bike lanes know what they are doing. The trash people leaving cans know what they are doing, and sanitation is probably the most corrupt department in this city. My councilmember isn't going to care what I have to say unless I have cash to donate/bribe, I have written plenty of emails and received plenty of canned responses about a variety of things in this city and operates autonomously. I don't have the free time to start a grass roots effort on trash cans in bike lanes of all things. The status quo contains an amazing amount of inertia, that's why little seems to get done in the name of public works. Such is life in American municipalities.

That's probably not true, at least in the sense that op intended.

It's almost certain that Steve jobs or Elon musk were much more than 3-5x more productive than the next best options facing their companies, for example.
The owners (or, for public companies - which most companies aren't - voting shareholders) are free to select whatever criteria they want for CEOs and appoint whomever they want.

If selecting a highly-relational project manager with a decade at the company would allow them to save a lot of money, they can try that out and potentially outcompete other companies due to slightly lower costs; and if selecting a very expensive outside CEO saves them some worry, that's a "service" they can choose to buy. If in the end the performance is the same and it's a waste of money, in the end it's their money (not, for example, the workers) to waste as they wish.
