> When this happens, that last bit of light the object emitted >>before<< crossing the horizon will now reach the observer in finite time. In particular, the observer will see that long _before_ they see the black hole evaporate entirely; one photon's worth of radiation is enough to do the trick.

(>>highlight<< mine)

You're not contradicting my argument: I'm saying that there is only a "before", and never an "after". Saying that light emitted before crossing a horizon is visible in a finite time is not incompatible with what I'm saying.

Keep in mind that Hawking's model is known to be oversimplified as well! In his simple evaporation model, the information encoded in the infalling matter is lost, violating QM information conservation.

If you simply assume that no infalling matter ever crosses any horizon, that it all just "blows up" very slowly from the perspective of an outside observer, then there is no QM information paradox, no inconsistent observations, etc...

If you disagree, please cite a recent paper.

Here's a nice thought experiment for you: What happens at the last moment of an evaporating black hole's life? How does the horizon "disappear"? Whatever you imagine happens, now update your mental model for a relativistic observer. What do they see? I.e.: Does the increased apparent mass delay the observed disappearance of the horizon!? If so, how can this be? How can two observers disagree on the presence or absence of this horizon? Now consider what would occur at this juncture if there was only smooth curvature, no horizon, and no singularity. Would this enable the last moments of a BH's life to be consistently modelled for all observers?
My understanding is that it is Procida’s work at Divio that was then later spun out into Diataxis, with Divio permission.

Claiming you dislike Arabica is a weird statement. There is a bigger diversity inside of Arabica varietals alone than in tea and wine.
So that part bends my mind.
> I assume that even an established company needs to go through 0-to-1 all the time

Not significantly. Massive product and strategy pivots are rare because they can fail horribly (eg. For every turnaround like Apple there's a failure in execution like Yahoo)

> How the great CEOs achieve their successes are beyond me

Luck in most cases.

I've worked with plenty of CEOs and in most cases, most people at the C-Suite and SVP level of large organizations are comparable to each other skills and intellect wise.

Administration/mid-level management buy-in is also critical. C-Suite doesn't have much visibility into the lower levels of an organization (it's unrealistic), so management is their eyes and ears.
Sounds more like a legal trick to create a department without following the proper laws.
As the sister reply says, Elon isn't going to be the head of a federal department at all. DOGE will just be an "advisory" group (wink, wink). Of course, Trump will probably do whatever they advise him to do as far as cutting things, so it's not that much of a meaningful distinction, but it is a legal distinction which should avoid the legal issue you refer to (Xitter being run by a department head).
UK Beeks Group claims 1000% price hike drove it from VMware to open source rival
Correct, that's why I explicitly said "classical" in that sentence. Classical relativity means our understanding from Einstein's field equations, prior to the information-theoretic approaches.

The senior engineers I saw there are talented. And Intel has benefits and stock packages that rival those of big tech. I think I can expand on your point by saying the more senior engineers were risk averse and on the verge of retirement, and the young engineers were just there for the Intel name or some other reason. There is surprisingly very few middle-aged long-term people down there. This would be expected in software (Facebook/Google), but it is a recipe for disaster in hardware where long term thinking is critical to advance lithography (changed don't happen overnight). I also was surprised by how few of Intel's engineers believed in Intel. The most stark observation I made was senior engineers would max their stock purchase plan, but many young engineers would abstain. If the engineers don't believe in the product they are working on, I don't accept that the gov. must bail it out. I hope some investigative journalist writes a book on Intel and Boeing someday, as I would be curious as to how things unfolded and got to this point. There are many similarities (I never worked for Boeing, but have friends in Seattle that describe the culture in similar terms to what I saw at Intel). Also, to your last point, the Intel name does not hold as much weight as it did in the Grove days.
>That's not really very surprising: back in ~2016 when Synology started using btrfs, these features were still somewhat nascent even though other parts of the filesystem were starting to become more mature.

btrfs was seven years old at that point and declared "stable" three years before that.

ZFS is an example of amazingly written code by awesome engineers. It's simple to manage, scales well, and easy to grok. btrfs sadly will go the wayside once bcachefs reaches maturity. I wouldn't trust btrfs for important data, and neither should you. If you experience data loss on a Synology box, the answer you'll get from them is "tough shit, hope you have backups, and here's a coupon for a new Synology unit."
That is fantastic news. I have always thought that paywalls have held humanity back.
That's a bit of a strange perspective:

1. We have some ideas.

2. Those ideas can't possibly be correct, because quantum gravity can't quite fit in.

3. Suppose anyway that the ideas are good enough; look at this cool equation.

4. Yeah, it doesn't... technically...converge, but the first few terms are pretty good.

Your comment about not knowing things in the limit yet makes perfect sense, but the motivating argument for that math in the first place is limiting behavior. It makes a ton of sense that none of these ideas converge, but it's peculiar that some of them are basically right for small terms when they're created from a foundation of convergence.
Show HN: Book and change flights with one email
Hi there,

TLDR; I built an inbox simulator so you can try BonBook in 15s, without sharing your email.

Earlier this year I was flying 2-3 times per month and found booking and changing flights a hassle. So I decided to fix it.

BonBook lets you find, book and change flights with one email. It can also auto-find flights for events you’re attending.

Over the last few days, I built a simulator that lets you interact with BonBook without sharing your email. It responds with real flights and each response includes a link to compare w/ Google.
Why should they tell you, or anyone else?

(And I see this is from The Intercept - a site that was the brainchild of Glenn Greenwald, an actual progressive thinker with integrity, faith in his convictions and reasoning behind his beliefs; but is now taken over by modern "progressives" who engage in nonstop mindless identity politics and slander him as a rightist. One of the great tragedies of our age.)
Tip awkwardness has played a surprisingly big role in me eating healthier. No I don't want to tip you for handing me a prepackaged muffin. But you're paid like shit with an eye on making up the difference in tips. So I guess the choice is to just not shop there. Which takes out almost all places I'd get a snack at during the day.
Sure, but we are capable of more cooperation than your fantasy admits. Let's wait until there's no alternative to misanthropic behavior to indulge.
I have...good pitch? If you play notes on a piano I will guess right significantly more often than I could by chance, and my misses will often be one note away. Not perfect pitch, and not useful in any event.
I got an oil change a few months ago and the system prompted me to tip. Needless to say I won’t go there again.

And to name and shame them for my Canadian compatriots, it was the Great Canadian Oil Change chain.
If you look at what happened at Twitter in the time before Musk bought it, one could argue that it's already been extremely political - just not on the side the EU would like.
Right but nature doesn't suck. You make humans sound incapable of cooperation when this evidently isn't true. In this world uncooperative behavior is mostly a choice. Particularly in the west.
I’m not convinced. Share a microtonal piece that can stand up against something by Chopin or any other great composer.
In just 4 years of Biden the Democrats got infrastructure spending, the CHIPS act, inflation under control, unemployment down to levels not seen in decades, eliminated billions in student debt, capped insulin prices, allowed Medicare to negotiate lower prices for more drugs, had multiple years of job growth every month, cut child poverty rates in half (from 12% to 6%), passed rules guaranteeing overtime pay for more workers (later overturned by a Republican judge), supported rail unions in getting paid sick days, criminalized sexual harassment in the military, invested in clean drinking water through infrastructure upgrades, prosecuted antitrust, blocked harmful corporate mergers, and more - but please tell me how they do nothing and it's all the same.
> The rollout of the ACA marketplaces is a prime example of what that capture looks like, a sub sub sub sub sub contracted and ultimately outsourced project that was riddled with bugs costing millions to create when literally if the fed gov had a team of software devs employed (perhaps some of the devs from the DOD?) it would have cost far less and would have actually worked.

You are probably overlooking a lot of complexity in the ACA marketplace software. It needed to exchange information with a bunch of different state systems and the systems of several different federal agencies, and most of those systems had not been designed to exchange information with systems outside of their state or agency.
I do think it is time for me to throw my hat in to the Silicon Valley ring. I could be an amazing Intel CEO. Give me a call.

The first bit of Ancillary Justice story is a slog like the first 80 pages of anathem and as purposefully confusing, but 3x longer.

I get why the author did it but and it was a good payoff on realizing and stressing inherent societal biases, like any good scifi should break your brain a bit and point out where you are being intellectually lazy. It just didn't need to be so long. And also the story just wasn't all that interesting if I recall. Kinda someone wandering in the wilderness iirc.

I actually liked the latter parts of the series once I got past that. Got more into a detective novel and some political intrigue. The gender bending/fluditity came into it's own at the end as you had many characters against current gender norms that you hear described through actions and then "meet" much later in the book, realizing all the assumptions you were implicitly making being wrong. along with all of the drones who wouldn't really have a gender anyway or might switch gender constantly, so why are we forcing our mental model of gender on them (fair enough).

If you like challenging your brain a bit power through the first book, but it's definitely not the traditional science only sci-fi. I see why a lot of people like the book and I see why a lot of people hate it because it's not a deathstalker novel. It's kinda like when my dad was really pissed when we watched the live version of Cats because "it wasn't what I expected". I was 8, and was like "what did you expect?" "I don't know, but not this" to which my 6 year old brother said "It's definitely about cats".
My understanding of Smith-Mundt (including its 2012 revision) is that being an "advisory body" would not meaningfully discharge the group's relationship with the US Government. Calling it a "department" certainly doesn't help the case.
I find it fascinating that they're announcing they won't be posting on X anymore, yet at least in the article OP linked, there is absolutely zero mention of where they will be posting.

This makes the announcement itself feel like a disingenuous, politically motivated, anti-X hit piece to me, rather than an informational notice about where people can go to read their content.

If this really is born out of their dedication to 'humanist values, our commitment to press freedom and media pluralism, and our fight against all forms of hatred and discrimination', then why is there no mention at all of where we can go to hear more about these positive values?
The Spysat and the Shuttle (2017)
What part of a Samsung merger do you think would help them enter the phone market? My layman's understanding of history is that Intel tried and failed several times to build x86 chips for phones and they failed for power consumption reasons, not for lack of access to a phone maker willing to try their chips or anything like that.
It seems like a "bit less accurate" is a misnomer here. If you can successfully employ this technique, and use calibrated test equipment to measure it, you have in fact demonstrated your accuracy in recalling the pitch of notes, also known as perfect pitch. The means of achieving this recall do not in any way affect the accuracy of the results, because the results exclusively speak for themselves.
All middle management done by AI having meetings with itself and making and presenting slide decks to itself and tracking it all in spreadsheets only it every looks at. The people at the top still get all the money and the people at the bottom still do all the work. But the middle will be so damn efficient we won't know what hit us. Amazing times.

Ask HN: New Resources for Learning Complexity Theory
A few years ago in 2021, I put together a guide to resources for learning computational complexity theory at the graduate level [0]. Think time and space complexity, hierarchy theorems, and circuit complexity.

For video lectures, for instance, I recommended Ryan O’Donnell undergraduate [1] and graduate classes [2] at CMU. To keep this up to date, I want to add more options for lecture notes and videos.

Have you worked through a new book or a recent set of lectures that were helpful?

Even young me knew at the time eliminating this was a bad idea.
you might be onto something. i always keep a dark roast in the freezer for making tiramisu. it just tastes better.
Exactly why I'll never visit twice any establishment that asks me for a tip. If I ever go eat in a restaurant, it's because I want to have less stress in my life, not because I want to put myself in a shitty situation where not only I need to be up to date with current social norms (which has always been a difficulty of mine), but I also need to do things that go against my beliefs (tipping is a scam akin to TicketMaster "€100 ticket + €20 shipping fee + €30 convenience fee + €35 what are you going to do about this fee + €15 fee won't make a difference = €200 vs advertised €100"). As a result, whenever I visit a restaurant, the thing I remember the most is not the food nor the ambience, but the moment of tipping when the waiter begs me for a tip like a Syrian refugee begs for water. This is not a problem in my country because thankfully begging isn't as common here, but when I was travelling I was once asked for a tip during a hotel breakfast, which BTW was shitty.

Also, tipping is a monument to human stupidity. Apparently, people would rather pay €10 + 20% tip than €12 with no tip, because the former feels cheaper, even though it's a stupid way to organize pricing.
Why do you think that's even remotely common?

An interesting thought experiment: what if a store let you pay by bank wire (let's say $20 fee)

Would you stick to your guns and say that cash users have to subsidize expensive wire fees? Or is that too much, and the fairness ends at subsidizing the expensive credit card fees? If so, why the distinction? If you could pay by bitcoin, should cash users pay the bitcoin transaction fees too? :)

Also, do you really think 3% is a fair tax on the entire economy that we should be giving to the duopoly of MC/Visa, when they only charge 0.3% in most of the rest of the world? The only reason they charge so much here is because they can get away with gouging due to our non-functional regulatory environment. I don't know why so many people accept 3% as a law of nature or something when the cost of handling cash is far less than that.
Huh, this wasn't supported already? Wonder why they decided it was finally time to take the 30 minutes to create an official .NET buildpak now vs 10 years ago when it became cross-platform.

It’s great to see more innovation in the robotics framework space, it’s sorely needed.

Looking for application security engineer roles.

For the past 5 years I have been building security tooling that internal teams can make use of. I work closely with other teams to help improve the security posture of their apps. I help write documentation and host department wide presentations to educate others about web app security and steps they can take to make apps more secure. I took on the responsibility of managing our H1 Bug Bounty Program which previously was failing SLA targets by 10+ months and managed to bring it down to days. I have helped mentor interns and junior developer and also been active in conducting pair programming interviews for future candidates. What you get from me is a go-getter, self-motivated individual. I am always looking to improve not only myself but also my work.
There were also people saying "science is a scam, scientists can't be trusted, do your own research" and I'm sure that didn't help.
Take a look at the Hugo Novella shortlist authors associated with Tor from 2016 to present[1].

I poke at this specifically because Hugo shortlist authors---with the lesser Novella Award serving as gateway---tend to generate exceptional sales figures relative to their peers, and Tor authors have had a statistically overwhelming shortlist presence over the past decade.

Filtering on non-female authors:

- Dexter Gabriel (P. Djeli Clark) wrote three unrelated novellas, all of which were shortlisted. The Haunting of Tram Car 015 was a warmup to his Nebula-winning novel A Master of Djinn. Arguably the most notable example, but doesn't quite fit the implicit business strategy I was alluding to...more like take random novella shots and further develop the thing that sticks, as opposed to committing two novellas to a strategic theme while reserving the option to follow up.

- Victor LaValle got a lot of attention across the board with his novella nomination, but jumped ship to a Penguin Random House imprint for his breakout novel The Changeling that was produced into a television series for Apple TV+.

- Kai Ashante Wilson wrote two related LGBT romantasy novellas; one was shortlisted. Sales clearly just wasn't there.

- Daniel Polansky...doesn't have a wiki page. Nomination was for a single standalone fantasy novella.

- Neon Yang and Nino Cipri identify as "they". Both were nominated for LGBT fantasy novellas; the former's Tensorate appears to have hit better sales metrics relative to the latter's LitenVerse.

- Adrian Tchaikovsky was already a reputable science fiction author riding on laurels, so doesn't fit the implicit business strategy; his nomination struck me as more "traditional".

lol, 小红书 as an idea was established way before facebook.

facebook was just trying to use an adbuster's style approach, but actually during that time there were tons of subversive messages, e.g. mckenzie wark's "hacker manifesto" was commonly read and discussed. that whole hacker-chic is what facebook and PG modeled their entire personality off of. even though they might not have cared about edgy communism back then, the GNU manifesto written 20 years even earlier (and lots of FOSS warriors) certainly did.

even back when facebook had their little print poster shop on their campus, a lot of hackers outside felt really grody seeing this anti-capitalist spirit co-opted by this financial behemoth. it was like every 2 weeks someone would know someone else's small startup get snapped up for $10s of millions here and there. it was like watching the air slowly get sucked out of a party.

predicting the false positive before it happens is a likely spin-off.
You’re right about how this decline happened.

But encouraging people to share to the widest audience was another aspect where short-term growth of metrics was prioritized over long-term health of the platform.

There was a possible future where FB leadership didn’t get worried about/envious of Twitter and push so hard on public sharing. But that type of call was solidly on Zuck and not Sandberg.
