"Other images show the "sphericals" as being hollow and easily crushed by the treads, and having stalks, and growing together."

This is an example of "proving too much". If Mars had plant life developed to the point of having stalks and visibly growing in macroscopic amounts over this time frame, we wouldn't be "debating" life on Mars because it would be plainly obvious that it has life, if life was that active.

This is why we discuss whether or not it has a micro-organism based ecology that it is hiding, rather than discussing whether or not it has forests that we just haven't found yet.

I've noticed this is one of the key signs you can use to identify cranks massively overfitting data about life being here or there.
And where in that false dichotomy do you put raising children?
It may self-correct. If I'm trying to write for Reddit, Reddit is fine. If I'm trying to write for the world, and Reddit no longer makes things publicly available, then I won't write on Reddit any more. If the people worth reading outside Reddit start doing that, it may hurt Reddit's traffic.

So it may self-correct. May.
It's popular to be a victim these days. Much more popular than I recall it being earlier in my lifetime. It even goes so far as to regard people who aren't victims with contempt.

In this domain it is quite a bit of headroom. Normal companies just avoid the problem by splitting before they get even within two orders of magnitude.

So if this next-closest share price got closer to the limit, it would almost certainly split long before it became within one order of magnitude of the limit.

BH is just a different duck that way.
It's more accurate to say "never use floats for accounting." You should be able to state with 100% certainty how much money you owe no matter how much money you owe.
> this is basically a trompe

Is it though? They don't really explain how it works or show any diagrams, and they said it was "inspired by" the trompe. So I'm a bit confused on that point.

It really looks more like a mashup of a centrifugal compressor and a diffusion pump. One where water instead of oil is used as the working fluid.
No they knew it but this particular feed having the issue is an older NASDAQ feed.

NASDAQ's newer feed doesn't have this issue but a lot of major institutions don't like updating their infrastructure so they stick to the older feed.

To be honest, it's not nearly as big of a deal as it's being made out to be. It's not a situation where NASDAQ was ignorant of this issue or neglectful, it's a situation where NASDAQ has to balance support for legacy systems by not doing a binary incompatible update to a protocol that has worked well for many users for 20 years... versus pushing older institutions to update to their newer technology which doesn't have these issues.
> The idea that you're going to shove 1TB of data down to the client strikes me as slightly unhinged

Yeah which is why I asked for clarification from them because it seemed really weird to assert that as a positive for the app?

> It would be much faster, and, I think, simpler, to keep the data on a central server, have it generate the visualizations, and push them down to the client.

Yeah I completely agree but in this case, Mighty would have next to no advantage over just loading the visualization on your own machine. Hence, again the confusion about asserting Mighty as a means to an end
Even if you think you are immune, you probably agree ads attempting to psychologically manipulate people into buying a product are unethical?
Slightly tangential: it looks like some of the sounds your units make in Age of Empires II when you direct them are apparently just phonetic sounds. Specifically in the bottom two sections ("Other symbols" and "Affricates"), a number of those sounds appear to be the exact "words" your units will use on occasion. I thought they were actual words but apparently they're just letters / phonetic units (not really sure what the term for this is)!
oh, that's a great chart, thanks for sharing!

Normally issuers would just split the stock. When investors' systems break because your quote is 100x anyone else's you're just making everyone's job harder.
This gets back to what I said about comparative advantage. The monetary transfer is only bad if you assume the company can only gain if you lose and the situation is zero sum. If you using toothpaste is good for you, and good for the company, what's the issue?

To use a more current example: would Pfizer marketing in a way that intentionally appeals to anti-vax people be mind control to their detriment?

Taking a step back, there are at least (but really I think only) two reasons for an advertisement: to raise awareness or to convince. The first clearly isn't unethical. Saying "we exist" isn't really mind control, and results in a more informed consumer. I admit that most ads that appear to do that don't just do that, but an advertisement that simply points out that Colgate is a Toothpaste brand that you can buy Is ethical. Its exactly the same as putting your logo on your box (which is a form of advertisement!) and having your box at eye level on the shelf (which is also a form of advertisement!!).

The second type convinces people that one act may be better than another (our brand > their brand, or brushing > not). These can be ethical or not, but GP stated that, essentially, advertising is always going to be detrimental to the consumer, which implies that everyone is already acting in a globally optimal way. That seems immediately suspicious, does it not?
You can do this in the browser already. In Firefox, go to Preferences → Language and Appearance → Advanced and untick "Allow pages to choose their own fonts, instead of your selections above".

The user experience is that it improves the vast majority of sites, by not having to read in 80 different fonts on 100 different sites, and breaks a few sites in minor ways because some text ends up overflowing their boundaries.

It would be great if this became the norm again. Content is king!
Certainly. The lesson I took from this was that the risk of data loss is much higher on the MacBooks these days because the it's not simply the chance of the SSD failing that could cause data loss but also a failure of any of the motherboard components as well. It's something I hadn't considered and something definitely worth keeping in mind.
> You are either deliberately misleading people or are ignorant of the UK education system.

I don't think either is necessarily the case - he isn't saying it's easy to become a doctor in the UK, he's saying it's easier than in the US, and that's sort of true, if not by all that much.

In the US you also start university at 18 - med school is a 4 year degree you must have completed your undergraduate degree to begin, then you go on to train for 3-7 years as a resident, depending on specialization. Then maybe more for a fellowship.

That said, I've got both doctors trained in the UK and in the US in my immediate family, I don't really see much of a distinction in difficulty of training to be honest but I'm not a doctor myself so what do I know.
Ask HN: Reading PDF Documents on Cell Phone?
Has anybody ever wished that they can open a PDF file on the phone and read it like a responsive webpage, with readable text size and reformatted paragraphs? Is there an app for that? Would anyone want to use it if such an app was developed?

I come across this problem from time to time. All I do is rotate the phone and squint at the tiny text…
The problem I see is that the advertising business enables free services such as Google and Youtube, Facebook, Twitter to dominate. It's even more difficult for a potential competitor to gain users when competing against a free service. Another is the spying and tracking, which are apparently vital for these big companies to grow.
Its more so frustrating to me that they become tribal by necessity!

The ads I saw included images of alcohol.
> Not at all! First I talk about the economic benefit of targeted ads

I wish that my ads would be more relevant to what I like especially when it comes to music. What does youtube do? I search for a specific video because somebody told me it's there. I find it and sit through the whole length of 50+ mins and after I'm done navigate back to the YT frontpage. What do I see? A recommendation of the video I just watched. And it'll stay there for the next 6 weeks.

The other extreme for me is watching something from the other camp simply because I want to learn what they're being exposed to. In my bubble this means conservative stuff like videos of people debating Ayn Rand or a Jordan Peterson. And I swear I'll have to fight for the next 6 months to get similar shit off my timeline. In fact it's easier to throw myself into the rabbit hole of watching Foucault, Zizek, Philosophy genre and fighting my way into content that is dominated by the likes of Tucker Carlson (and what used to be Alex Jones, Brietbart and others) than it is to shed the conservative label that YT has filed me under. And with conservative I mean seriously questionable stuff like Q-anon, climate change denying, cray-cray type of things.

Because of this I now have different accounts for when I want to see the other side of the coin/polarization.

Not sure if I should be blaming YT/Google with this since society is so polarized that the algorithm just reflects that reality. But it's not like the algo hasn't played a major role in creating this dystopian reality in the first place.
> Willingness to do things by hand (such as sewing improvised masks in spring of 2020 at home).

This is good and bad. Nobody I know can recommend me a plumber because "we all know how to do that ourselves" - ironically the reason I need a plumber is because of a shoddy DIY job performed by previous owners of my flat :D

And as an aside - I was really sad when N95 and FFP2 masks were mandated. The psychological boost of everyone wearing their own lovely little custom masks together was really cool and bonding. They were the last connection to the early successful response to covid, when they were deprecated it seemed to be around the time where everyone just sort of gave up.
There are some great sensor options out there and they are dirt cheap (cents or a couple of dollars). ESP32 and ESP8266 are my chips of choice and they are also very cheap.

Some great projects are easily achievable from Arduino. It seems to be slightly looked down on as a platform, but I’m not skilled enough to know why. It has an IDE and a language that’s easy enough to use. There is also a huge community and a mass of projects out there.
ESPHome is another excellent project which takes the coding down to just yaml config files and then you can makes automations one Home Assistant.
Just anecdata but I saw the Amazon driver running the entire time he was out of his truck in my apartment complex.
Dropbox got big because iPhone users were so desperate to be able to share files between people and desktops that they started using it in droves. The desktop users that took it on were simply looking for some more storage and it just took off from there. There was no reason to pay attention to it initially (and still isn't imo) and over in android phone land everyone had no reason to either other than to retrieve files their friends sent them.
> When Chia mining really ramps up, it will kill off SSDs faster than a T-rex in a petting zoo.

It's possible, but the "farmer" would have to be very serious about Chia and also not have read any FAQs, not watched any videos, not visited any forums, etc. A healthy fear of plotting on one's boot drive is the first thing drilled into Chia-heads' heads.

> The mechanisms in the body that grew out your more complicated macro qualities are finely tuned to do all of it at once. Maybe we could micromanage it ourselves, but the actual body doesn't know how to do it itself.

The linked video in the grandparent post argues pretty convincingly that the body might know exactly that, actually.
I rarely agree with Elizabeth Warren, but in this case, she's right. If there were ever a justification for antitrust breakups, today's Big Tech Mafia is it.

These companies are way beyond the size and abuse levels of trusts and monopolistic companies like Standard Oil, which never even dreamed of, let alone possessed, the kind of power and control of even one of the big tech companies, let alone several of them colluding together.
Nelson is a good example to keep in mind of the headwinds against "Crazy New Ideas" (https://news.ycombinator.com/item?id=27061789 on the front page now).

Its called context.

A new one was created to convey a shared concept (aka the purpose of language) and will always be more popular than the thing you invested way too much time into to change.

It’ll sting at first but time to accept that and update your lexicon.
"isothermal" is the reason this system is more efficient right?

But is it the theoretically most efficient way to compress air? Is there a (theoretical) way to compress the air adiabatic'ly (letting it heat up as you squeeze it), and do better overall?
Interestingly, and from my anecdotal experience, this seems to be true across political and ideological divides.

"Just imagine traveling 10 years back in time and trying to explain this to someone; just imagine what an idiot you’d feel like. “There’s going to be this online currency that people think is a form of digital gold, and then there’s going to be a different online currency that is a parody of the first one based on a meme about a talking Shiba Inu, and that one will have a market capitalization bigger than 80% of the companies in the S&P 500, and its value will fluctuate based on things like who is hosting ‘Saturday Night Live’ and whether people tweet a hashtag about it on the pot-joke holiday, and Bloomberg will write articles and banks will write research notes about those sorts of catalysts, and it will remain a perfectly ridiculous content-free parody even as people properly take it completely seriously because there are billions of dollars at stake.”
So was the support.

The NN debate online was a massive propaganda warfare campaign between two teams of huge corporations, neither of which had any of our interests in mind. We were squeezed in the middle of it and everyone was pressured to take sides.
How would you send a report over VHF? From what I understand the only digital bands are DSC and AIS and that is broadcast only, anyone can listen in.

SSB is not a set and forget communication. It's great for long distance communications but the operator has to be seriously fairly knowledgeable on how to make HF work. It's a 100W radio that can do some damage if used incorrectly.

> This code is in a performance critical loop and it looks like a waste - we never run with the "debug" flag enabled[1]. 1. One historical solution to this specific 'if debug' problem is called "runtime nop'ing".

You know what another historical solution is called? Use a compile-time constant and let the damn optimizer optimize. (Virtually) no modern, widely used compiler would fail to optimize out `if (0) { ... }`.

Also, why does M1 performance matter to Cloudflare's software? I kinda doubt their servers are on Macbooks.
Based on the description, guessed 'nagle' without any debugging. Not sure if it implies I was right or wrong, but it explained Nagle's algorithm.

It's a mistake to think that only things which are "absolute" can be logically programing. Take this silly example:

> If x is a good person they can go to heaven. Unless they were born on Feb 29th. The previous restriction is lifted if the year is a prime number. The counting of the year is Julian. The destination of heaven is replaced with hell if at least 5 people are on mars.

As the article shows, exactly existing law is fully of "whoops, you better keep on reading to find that override" situations like the above. Formalization still helps by putting all branching up front rather than with the the moral equivalent of COME FROM statements. And that helps whet there or not "good person", "heaven", and "hell" are well defined.

...The responses to this prreprint make me think no only do HN readers not understand the law, but they don't understand programming well either. :/

The only way we will figure that out is to collect lots of data on it. Perhaps there are correlations in the MRI/CT that determine lethality/malignancy.

Even if we perform zero treatment, this data argument should be sufficient reason to increase rather than decrease the number of MRIs we do. CT is different since there is some radiation exposure risk that must be considered.
Ha, at the beginning I read the word novel as new. I was getting a little disturbed by this until I read on to understand this was fiction. Wrong novel :). Embarrassingly, this took too long to realize...
Hello! I have severe ADHD. It's the variant without hyperactivity, but in the newest DSM ('official' list of known disorders), they've combined ADD and ADHD into one (ADHD), as they seem to be variants of the same disorder (i.e. not two different disorders).

The single biggest thing that worked for me was medication. I can very much recommend. Please ignore people that say that you 'can work through it', or that handling things without medication is somehow 'better' or 'more natural'. This belief is stupid, wrong and needs to die.

The annoying part about mental health is that problems aren't visible. You would never tell someone with a broken leg to 'tough it out', or ask a disabled person to run a mile.

If you're diagnosed with ADHD it means you actually have a mental handicap / impairment. Just like someone with a broken leg, it needs medical attention.

Before I was diagnosed and got medication, I've tried every tool, every method, every strategy to organize myself, keep focused, or otherwise mitigate my problems that I was having. From GTD, todo lists/apps physical and digital, bullet journal, pomodoro, meditation, cold showers, making your bed everyday, journaling, the secret, etc. Basically all the things people are recommending in this thread.

I couldn't keep up with any of them. The biggest flaw in most of these systems is that you already need to be very much organized to effectively integrate these in your daily life. It never worked, and after a couple of months of trying to integrate such a new habit I would ultimately fail, and hate myself for it.

Since mental health plays a part in every aspect of life, this mechanism permeates all facets of life. It's hard to keep up eating healthy, playing sports, finding time for hobbies, working, keeping up with relationships, sometimes I even had difficulties keeping my attention while I was talking to someone, leading to some very awkward discussions sometimes. Ultimately it's VERY EASY for untreated ADHD to lead to depression like this, as it did in my case.

Only after I've started getting this chemical deficiency sorted by using medication was I able to really feel like I had any meaningful grip on my behavior.

Please, please, please! Don't make the same mistake that I made, and get tested for ADHD, if you think you might have it.
He certainly could afford to pay someone
My "smears" involved talking about how Reddit didn't ban the watchpeopledie and greatawakening subreddits until they became a public issue. People were making death threats in the latter, talking about secret messages from Trump. It's preying on mentally ill people. It's wrong.I said that Graham's influence encouraged Swartz to take the actions he did. To believe that the world was his oyster that he could hack without consequence, and that now the conspiracy subreddit thinks that Swartz is some kind of martyr for freedom.I promise you nothing I said is factually incorrect. You consider them smears because they "smear" the people that pay your salary. You do get paid for this, I hope?I accuse Graham of being dishonest because he won't actually directly discuss issues he has, instead he does it this roundabout way of posting essays, essays which you review and you have banning and moderation power over. You don't see the conflict of interest? It's punching you in the face. I consider Musk a liar, because well, he's a liar. I know Sam has interviewed him before.I did edit my post, but that's because I knew it wouldn't fly. You accused me editing it to be neutral of being "abusive". But I was editing it so it would not ideally cause trouble. But it did anyway because damned if you do, damned if you don't. Now you're trying to portray my edits as abusive. Come on, dude.You've never stood up for me, dang, when people are being pedantic and bullying. What do you want me to admit to? That I have a really strong dislike of you and Graham because here you are being manipulative for all to see? Yeah, I did. That you aren't honest with yourself about the "essays" that Graham attacks people in? Yeah, I feel that. That your moderation is arbitrary and selective and doesn't scale? Yeah. I'll admit, I'd never heard of that essay is French excuse, but it's a good one. I'll have to teach it to my kids (re: Uncle dang).This is a new account, not to be "abusive", because I logged out and don't have the password to the old one. I'm not so offended to call your accusations "smears", but please be aware this is a two way street.I wonder if you would have banned Musk when he called an innocent person a pedophile? Hell of a smear.
