A very nice fact that I coincidentally learned just yesterday, which is not in the linked answer but is touched on in one of the comments and in an edit on the accepted answer: there is an explicit bijection that maps a binary tree to seven binary trees (and vice-versa, by the inverse function).

Consider the definition of a binary tree: "a binary tree is either empty, or is a root with a left tree and a right tree". This we can write as

T = 1 + T²

Solving the analogous equation z = 1 + z² in the complex numbers gives z to be a primitive sixth-root of unity (https://www.wolframalpha.com/input?i2d=true&i=z+%3D+1+%2B+Po...), i.e. z⁶ = 1, and so z⁷ = z. It turns out that we can similarly show T⁷ = T with some algebra (without subtractions) by repeatedly applying the transformations T→1+T² or 1+T²→T (a "game" version is at http://lebarde.alwaysdata.net/seventrees/):

T⁷
= T⁶ + T⁸
= T⁵ + T⁷ + T⁸
= T⁴ + T⁶ + T⁷ + T⁸
= T⁴ + 2T⁷
= T³ + T⁵ + 2T⁷
= T³ + T⁶ + T⁷
= T² + T⁴ + T⁶ + T⁷
= T² + T⁵ + T⁷
= T² + T⁶
= T + T³ + T⁶
= T + T² + T⁴ + T⁶
= T + T² + T⁵
= 2T + T³ + T⁵
= 2T + T⁴
= 1 + T + T² + T⁴
= 1 + T + T³
= 1 + T²
= T

This can be used to give an explicit bijection: see Andreas Blass's paper "Seven trees in one": https://arxiv.org/pdf/math/9405205 (via https://twitter.com/CihanPostsThms/status/157901771352705024... — see also https://math.ucr.edu/home/baez/week202.html which has more.)
Unfortunately booster packs are the only way they can profit and create a meta game. The biggest scam of them all are the printing ratios. They will print a fairly strong game breaking and defining card but only in short prints meaning you will probably get 1 copy out of 2 boxes (boxes prices above 80$ depending on the game). Hence the high demand and low supply will rule even the secondary market adjusting prices the way the companies intended. That's how a game dies.
The retraction is right in the article's sub-title: "...was designed to withstand gale-force winds and powerful storm surges..."

Even the most generous interpretation of "gale-force" wind tops out at 63 MPH ( https://en.wikipedia.org/wiki/Beaufort_scale#Modern_scale ). Ian was a hurricane (defined as 73+ MPH, Ian hit 155+ MPH). The wind's destructive power goes up as the square of velocity (or worse). Then there are storm surges plus waves, and the article's 2nd paragraph notes that it was built on a sand spit, which was on an island which Ian completely submerged.

So...yeah. This is "news", about the same way that "Army's newest tank-killer weapon can punch right through a pistol-bullet-resistant vest" would be news.

Everyone of us has such personal guidelines / biases when it comes to social interactions. We all form such conscious and unconscious biases about certain community based on whom we interact with and it is ok up to a point, if you don't take them too seriously (or these biases can become narrower and fundamentalist). Working with people of different culture always requires us to step out of our comfort zone to varying degree. Obviously this is uncomfortable. But as with any learned behaviour, avoidance only exacerbates the issue and practising it more and more makes it easier.

Your problem is with buying a dell or hp laptop. They're known to be crap. Buy by specs and look at other brands.

The 2 macbooks I've had shit the bed within 5 years and cost ~$2k each. Both have also required repairs, so add to the costs. The PC laptop and desktops I've purchased/built for under $1200 each have been running smoothly still (laptop for 5 years at ~$900, and a 10 and a 6 year desktop $1100-$1200), haven't required repairs, and don't see any need to upgrade their performance in the near future (tho an rtx 3090 would be nice for running certain ML models).

Yeah windows ui sucks, but the cost to performance ratio for the hardware is way better than an Apple laptop, especially if you build your own desktop. Not to mention, you can always use a linux drive or dual boot if windows ui is that much of a hassle.

I think we should ban all stock transactions that aren't simply buying or selling shares for personal possession. Calls/puts, options, futures, etc. are just bets that are less complicated for corporate investment banks to automate strategies than for individual retail investors, leading to an obvious power and information imbalance that guarantees that the "house" always wins.

Which, if any of the list of 50 do you think is unreasonable? I don't always explicitly do all of these things all the time on every project, but I'm certainly _capable_ of doing so. For example, working in backend web dev, I generally don't go into it thinking explicitly about, say, memory usage, as long as my monitoring tools are not telling me there's a problem. Of course, there are exceptions, which is why I said "generally" (for instance, if I know I'm making a query to the DB that's going to yield 100k results, I'll definitely be thinking about memory usage), but I also don't just YOLO it and see if things crash.
ROE for cyber are fundamentally different. You deliberately do not "shoot to kill" in cyber, for tons of reasons, at least one being it's a much more opportunistic environment; hacking isn't magic, and many systems aren't penetrable at will. You often don't get to choose exactly what you target, you just hit what's vulnerable and see how you can pivot.

Flip the incentives for a sec; the group that executed this hack can present it as an "attack on American infrastructure" to their superiors, even though we here in the US know it was 100% ineffective.

I have been using FF on MacOS. Will checkout this. I moved from Chrome and finding this good so far. I face two issues though:

1. Switching on/off VPN would hamper the connectivity (sometimes only), not sure if this specific to my network

2. Responsiveness is an issue, key type response is slower. I will check if this new version helps.

Thanks FF team for your efforts.

> Vim is available on ~every machine I could possibly interact with.

This is my exact reasoning for sticking with Vim. I use Neovim on my desktop, but I work with servers and have a homelab where I just want the greatest common factor. Nano is also an option, but just like you, my Vim muscle memory is embedded and I end up with :wq everywhere.

Is Helix cool? Absolutely. Will it replace [Neo]Vim? Not until it's installed by default everywhere, and that won't happen unless it has a compatibility mode for Vim shortcuts.
Agreed, this is a terrible headline designed exclusively for clicks.

I’m quite surprised in 2022 that news coverage is not mentioning the now well-known risks associated with colonoscopies. AIUI they are no longer recommended in the EU for routine screening because of the very high rate of dangerous side effects, on net increasing all cause mortality in the general population.

The article here just looks at cancer mortality, which is not what anyone should care about.

If they truly do a cyber attack on infrastructure like they’ve been doing to Ukraine it will end in war. There’s a reason they are only attacking the wait time pages and not airport operations.

Read the book This Is How They Tell Me the World Ends: The Cyberweapons Arms Race
by Nicole Perlroth. It has a chapter that shows a lot of what has been going on in Ukraine. One quote that stuck with me was a Ukrainian saying you guys (US/West) are next, they are practicing on us.
Every article about "cyber" is fundamentally fearmongering, because they incorrectly analogize to the physical world where security is outsourced to an ambient third party (post facto law enforcement), implying an attacker is the purely responsible party. In digital reality, this headline would be more appropriate as "Airline website insecurities taken advantage of by Russia to disrupt business". The focus should be on the irresponsible duct-tape-and-string operations these businesses are running, rather than the people half a world a way sweet talking the computers into misbehaving.
When you attended a Powerpoint presentation in person before covid the chance of the presenter's laptop wanting to scan and update itself in the middle of the presentation was almost certain.

If only the Mac keyboard would look at the utility of the classical Thinkpad keyboard for design ideas. The bottom right corner where the arrow keys are.
It doesn’t actually matter if there’s an everything app or not - even markets with competition, like the US news media, or even our current social media landscape - are subject to the same concerns of cohesive and authoritarian-like control over a population, for which the author expresses concern.

Forcing apps and services to adopt open standards is also potentially problematic. If a government body chooses the standard, then they can also exert control over the limitations and features that must be implemented.

I do think we need legislation to promote openness and interoperability, but that does not have to mean that every thing anyone builds must adopt the same set of standards - only that they allow for and accommodate certain user actions and accessibility.

Ask HN: Anyone using MacBook M2 Air for development?
I'm in the market for a laptop and I'm choosing between the Pro and Air.

I use my laptop for development (not machine learning work). The heaviest thing I run locally for dev is one or two node powered frontends at once.

I do not use it for any type of music/video editing. I run an external 4k monitor and have apps like VSCode, Slack, Safari, Chrome, and Notion open at the same time. I don't expect other people to have this exact workload, so all comments welcomed!

I'm curious if people are using the Air with success.
The issue is that your comments have been full of presumption, which I personally find rude (in addition to being unuseful and uninteresting)

For example, it's not clear that you've considered that the people you're replying to have learned the subject matter and are reflecting on what would have made the process easier for them.

> It is practically impossible for person in China to opt out of WeChat.

I call bullshit on this one. All necessities are also covered by AliPay, and you just need to convince your contacts to communicate through good old phone call/SMS/email/one of the alternative chat apps.

WeChat only dominates all aspects of your digital life if you let it. There’s a huge amount of competition for every single aspect. Citing Gruber on this topic is as good as citing a random Chinese person on Facebook usage in America.

Source: got by in China myself with practically no WeChat usage, certainly nothing essential, for a long time.

>I'm surprised nobody's hit YT etc for violating the ADA.

Does YT fall under ADA? It's not a broadcasting platform. It is user generated content. Not sure if that falls under ADA either.

I've been part of teams scrambling to populate back catalog content with captioning (not-subs. they're not the same) for existing streaming content. Lots of 3rd parties involved, lots of buying of software to handle volume when 3rd parties become too expensive, etc. The cheat was to turn subtitles into captioning, but not doing the actual information for the hard of hearing.
If you've forgotten something then you don't have that knowledge anymore. So remembering things for longer means you are effectively gaining knowledge.

It's like someone giving you $10 and then trying to argue that they haven't actually given you $10 because just a few minutes ago you had a $10 bill in your pocket but you spent it on something else.

Let's be honest here, a green junior or intern could easily whiff on 45+ of these things and not get fired, as long as they're in a healthy workplace and they have a growth mindset. I literally tell interns at my company that I basically expect them to know fuck all, and that their opportunities at the company are mostly limited by their work ethic, their willingness to ask questions, and their desire to accept and incorporate feedback.
> Over a dozen airport websites were impacted by the "denial of service" attack, John Hultquist, head of intelligence analysis at cybersecurity firm Mandian, told ABC News. That type of attack essentially overloads sites by jamming them with artificial users.

That's not a "senior official"; "official" implies government, that's a company.

Yes, I would like to know the government agency official providing this information.

>” Killnet," a pro-Russian hacker group, is believed to be behind the attack, according to Hultquist. While similar groups have been found to be fronts for state-backed actors, Hultquist said there is no evidence the Russian government was involved in directing this attack.

What evidence supports this? IMO it's coming from that unspecified official. And yes, I think evidence needs to be provided before claims are made. They're just saying "I think it's these guys" ... because?
This wasn't a value judgement BTW. I acknowledged the valid and productive use cases for this project but pointed out that it wasn't revolutionary in creativity or innovation at this stage.

IMO it is not that surprising that neovim has had some success, in the same way that it isn't very surprising that SwayWM has had some success. They both have the benefit of, in many cases, being completely compatible with the tool they want to replace. Being almost completely compatible with the old tool, while integrating a popular new technology (LSP or wayland) seems to be the only way to win over users who already have a strong connection to their tools of choice.

My vimrc already has a bunch of configuration in it, I'll give Helix a try when it is able to parse that (so, probably never, I guess).
...the source literally isn't anonymous, it's Mandiant (not Mandian, that's a typo), and Mandiant has released so much evidence to back its claims over the years that if you can't by now at least give some credibility to the Mandiant name, you're not acting rationally.

He also directly states that this group is Russian but not acting on behalf of the Russian government in this case:

> Hultquist said there is no evidence the Russian government was involved in directing this attack.

I think it happens in certain circumstances to any type of people, not just East Asian. The same could be said for the Turks. They are also very much into their own culture, and are ethnically homogenous, despite being previously an inclusive and imperial society. The United States can be said to be like that to an extent but with two separate cultures instead of one.
I don’t know about the details in this case, but hacking (particularly DDoS) groups can be remarkably childish: they sometimes intentionally leave their name in requests, knowing that it’ll show up in logs.

The other identifying technique is correlation: if they’re using a network of hacked devices to create a flood of traffic, any previous attacks that saw traffic from those same devices are possibly from the same group. So it’s possible killnet has a public chronology here.
