"Ufimtsev has shown us how to create computer software to accurately calculate the radar cross section of a given configuration, as long as it's in two dimensions," Denys told me. "We can break down an airplane into thousands of flat triangular shapes, add up their individual radar signatures, and get a precise total of the radar cross section."
Why only two dimensions and why only flat plates? Simply because, as Denys later noted, it was 1975 and computers weren't yet sufficiently powerful in storage and memory capacity to allow for three-dimensional designs, or rounded shapes, which demanded enormous numbers of additional calculations. The new gneeration of supercomputers, which can compute a billion bits of information in a second is the reason why the B-2 bomber, with it's rounded surfaces, was designed entirely by computer computations.
Denys's idea was to compute the radar cross section of an airplane by dividiing it into a series of flat triangles. Each triangle had three separate points and required individual calculations for each point by utilizing Ufimtsev's calculations. The result was called "faceting"--creating a three-dimensional airplane design out of a collection of flat sheets or panels, similar to cutting a diamond into sharp-edged slices.
Tangential to this point, but I've seen firsthand in a limited capacity but also heard of this from other devs, but there seem to be a decent number of devs who go from job to job doing the same thing over and over again. An example I've seen: a junior dev learns Springboot at a job, then goes from job to job converting their microservices to Springboot. When that project is complete (can take 1 to 2 years in some cases), they get bored or change jobs for a bump in pay and do the same thing again. As they do this a few times, they become a specialist in that field and they start self-selecting to only doing that one thing over and over and over again.
Is this widespread? Anyone else noticed this phenomenon?
You don't cite your source for how much land is used for agriculture (and what definition of agriculture you're using). Are you sure this doesn't include land used for growing specifically feed crops and crops to make food oils, wheat, etc.?
Did HN do any kind of survey to demonstrate their user demographics?
And it is absolutely toxic on certain topics, particularly anything economics related or that challenges capitalism and the "line go up" mentality of the VC culture. If you offer anything that criticizes that at all, you're in for an earful.
Everyone with strong ideological passions thinks that HN is stacked against them ideologically. People routinely say that not only about the community, but about the mods. These perceptions are entirely predictable from the passions of the perceiver.
Who's right? Neither. It's exactly the same perception, just with opposite polarity, because the polarity is coming from inside the person.
More precisely, both are right in the sense that HN generates enough data points for everybody to run into whatever they dislike the most; and both are wrong in that they dramatically overweight that sample, because that's what the brain does with samples like that.
What makes this perception so common on all sides is that HN doesn't partition the site into like-minded siloes (e.g. follow lists or social graphs or subforums). Everyone is in the same big room, so everyone is frequently bumping into views they dislike and normally don't have to deal with as much, at least not in their home base. The irony is that this is actually a step closer both to reality (society is divided on divisive topics) and to genuine tolerance (bearing the presence of what one dislikes). There's more about this here: https://news.ycombinator.com/item?id=23308098.
I don't think HN is stacked against me ideologically, quite the contrary, my views are fairly pedestrian and middle of the road for the West Coast tech industry.
I do think that when it comes to politics and social justice HN is content to let people who aggressively hold certain viewpoints have an outsize role in the discussion, despite engaging in toxic behaviors that wouldn't be tolerated on other threads. This may be because the people running the show here are sympathetic to such views, or maybe they're just naive.
No we are not "content" to do that, and generalizations like this are notoriously unreliable. I'd like to see specific examples, and I'm sure interested readers would appreciate links as well, so they can make up their own minds.
A particular user is aggressively confrontational towards every queer/POC person who makes a negative comment about the Midwest possibly not being safe for certain groups. In a conversation about a technical topic, this type of behavior wouldn't be tolerated. In this case, it was, and possibly valuable discourse was derailed.
For purposes of comparison, there's a critical discussion about MS Teams today with a hundred comments. I wouldn't expect posters who respond "what are you, some kind of Slack shill???" in such a thread to last long here without moderator action.
Seen this double standard consistently over the years and it's one reason myself and others keep their distance from this site.
If it seems to you like there's less moderation happening on that sort of comment than there is on comments complaining about corporate product, I can see how that would lead to resentment about how HN is moderated. I wouldn't want to be part of such a place either.
Because there's a degree of randomness in what we happen to see, and we can't moderate what we don't see, there are some comments on every topic that end up not getting moderated. If it's a topic that's particularly important to you (I don't mean you personally, but any reader), bad comments going unmoderated on that topic are going to make a more painful and deeper impression. This perhaps leaves the sense of a double standard because more pain has been caused by those comments than by others.
I don't know what to do about this other than remind people that we don't see everything, that the likeliest explanation for egregious comments going unmoderated is that we haven't seen them, and that we welcome heads-ups about egregious comments that we're missing. https://hn.algolia.com/?dateRange=all&page=0&prefix=true&sor...
dude the fact that you are sooo touchy about this and jump immediately to the defensive with this sea lion shit the second someone impugns the conversational style of hn. it really undercuts that sense of detached impartiality you like to front with otherwise.
anyway man we made up our minds already that's kinda the point. hn has a lot going for it but it also sucks pretty hard, in some ways that are very difficult to quantify but nevertheless are real! I'm sorry that hurts to hear and I'm more sorry that you're so sure it can't be the case that you can't see it.
This comment is far below the expected HN standards of civility and decorum ("you are sooo touchy about this" and pointless accusations of "sealioning" in response to a reasonable question would not be generally OK here). I point this out not so much to engage in foolish 'tone policing' and purposely ignore its substantive points (such as they may be - the OP is actually more helpful here! And you have quoted a New Yorker description elsewhere in this thread that also provides a valuable outside perspective; we of course appreciate that) but rather to point out that HN takes criticism of itself very seriously, to the point of routinely giving comments like this one what amounts to special treatment. As a user base, we really, really want to avoid the tone-policing trap. And we'd like to see accurate information about these things even when that's hard to quantify.
that is the point I'm trying to make. we judge comments on how well they adhere to our standards of civility and decorum, but not by their actual effects.
having a mod jump on you demanding peer-reviewed validation if you criticize the place is bad, even if they do it civilly.
hn surely does "take criticism seriously" in the sense that when any is detected, it is fully and publicly focused on. but in all the cases I've seen it comes with a hostile degree and intensity of interrogation that makes it hard to believe it is a good faith exercise in organizational-self improvement. it just puts such a high burden and consequence on publicly pointing out the faults that people don't want to do it.
shit I try not to do it on purpose because it's such a draining unpleasant experience to be the center of attention of dang and whoever has decided to be his crew for the day.
being civil doesn't protect you from these arguments! these things are bad, no matter how civil people are being about them. and I am sometimes not that civil about them, but that doesn't make me wrong, or a moral inferior to people who can keep their cool.
On the contrary, I think HN is trying its best to be a broadly appealing place for intellectually curious folks, especially those who might be interested in tech and the business environment around it.
HN demands other things beyond civility and respect for others of course; we're all well aware that civility alone does not suffice. But it helps enough that doing away with it is clearly unwise, most of all during the sorts of vigorous debates that arise quite naturally in any discussion-focused platform. (Including very mainstream ones like Twitter, Facebook, LinkedIn etc.) This is not a "moral" point of view, but one that's driven by solid observation of what happens to overall quality when incivility and personal attacks are allowed to fester. Many of us have been on Usenet after all, and can draw from that experience.
> demanding peer-reviewed validation if you criticize the place
This is not what has happened here, and long-time HN users should be well aware of that by now. No "demand" was made backed by mod privileges, least of all any sort of "hostile interrogation", what I saw was gentle pushback, most likely aimed at trying to find ways of making any criticism actionable and part of a potential "exercise in organizational-self improvement".
I also take some issue at the implication that I share dang's outlook on these matters, to the point of acting like his "crew". What I did was merely to point out that your comment was phrased in a way that may well have turned many HN users off from its relevant points, but that it did nonetheless have substantive points to make.
I can't even really engage with this because it's not what I was talking about? any political issues here are far downstream from the larger ones mentioned in that new yorker quote above. which are, sorry to say, completely on display in those two comments.
the point I guess I'd like to make here is that you can be either ruthlessly rational data-bound defender of hn's honor OR impartial mod who applies the rules as written. but not both. or if you have to try to be both at least use an alt or something because these really should be separate roles at this point.
I think it's more important to be as I am, with whatever messy contradictions show up. Partitioning that into abstract roles feels weird and false to me. I wouldn't like to work that way, and it would make the relational aspect between mods and the community much harder. Since the relational aspect is the most important thing, that would be a bigger mistake.
> In this case it would be instead of having premium student dorms on the top floor for wealthier students, or rooms for the student dorm administrators, instead every student gets access to that penthouse common space.
I've never seen any dorms with "premium" student housing, let alone mixed in the building. There are certainly (especially older) dorms with more desirable rooms, but they were never "premium" or unavailable to any student.
