I started writing a complex demonstration, but the intercept theorem, (Thales' theorem) indeeds shows quite nicely that from a ground station, tracking a plane flying at (𝒽1,𝓋1) means the beam goes at 𝓋2=𝓋1*𝒽2/𝒽1. So, 5 m/s for a bird at 200m.

That said, I was mostly imagining space-based stations.

In the above case, I talked about ground-based stations at airports. Unfortunately, those would require high angular velocities, but would already be in bird-restricted areas (airports use all sorts of tricks, including drones, sounds, people chasing them, etc, to scare away birds). You could also conceivably drastically lower the beam energy output by using multiple beams that concentrate at a single point.

Now, a fun calculation: what would be the tipping point between birds saved by not emitting carbon dioxide and birds killed by the towers, if there is one?

One last point: I'd hazard that the bird is likely to change direction if it starts running into a beam and it has time to (ie, it is not killed "instantly"). This drastically lowers the dangerous altitude range, as the bird is less likely to fly in the same path as the beam (how likely was it in the first place? One would need to go faster than the other to catch up, but not too much to actually dispense the lethal dose? I haven't done the math, but I'd say it's quite unlikely).
> IANAL (or economist)

And true to form, your following statement was not what lawyers or economists would call price gouging.

As with most things, there is the colloquialism, and then there is the law. Price gouging laws are almost impossible to run afoul of, because thats not how this country is run. There are limited temporary state-controlled market disruptions, activated by a State of Emergency declaration.

> There are no garage spaceships, automobile plants, novel surgical procedures (I hope), or nuclear reactors (excepting that wacko who tried to make one from material from hundreds of smoke detectors and turned his yard into a superfund site).

The thing is, when I realized this, these things stopped being cool.

I think there was a lot of hope a long time ago that future technological progress was going to be a lot more open to individuals than it actually is now.
As of this writing, a lot of comments are sharing their varied personal experiences in WFH.

Which is good, because they are all more interesting and valuable than the article, which skips the "varied" part and basically lumps everything in to "if you have troubles working from home, you need more willpower" (paraphrase).

I found it insulting and was a bit surprised to see what I assumed to be American work-fetish from a BBC article.

There are LOTS of reasons because people are very different and our environments are very different. I don't have kids, I am easily distracted by visuals or sounds in my periphery, I have a separate room for my home office, I don't have neighbors that share a wall or live above my ceiling, I have good internet service, I'm an introvert...so yeah, I have an easier time working from home. But those that don't, they obviously just lack dedication to work. Garbage.

Not everyone recommended it to the masses. Some cautioned against it from the get-go - and Google was a problematic company with too much power already when GMail was being rolled out.
just having the UI definition given in native code already is a gigantic boost in terms of latency since you don't have to setup a whole javascript engine and HTML DOM to reach actual UI code though, just pass a pointer to the root of your widget tree to your paint function and see magic happening.

e.g. compare Telegram made in Qt Widgets with Signal made with Electron - the latter is incredibly slow to come up (and has broken text rendering) while the former is more or less instant on my machine (which is an overpowered i7...): https://streamable.com/m48hg7

fun fact: approaches such as Qt or also Flutter from what I could see can be more performant than some of the OS-provided UIs of some platforms - in particular Android is a pretty slow mess while Qt has seen a lot of work poured into running on <1Ghz devices.

I'm very glad that Minecraft was successful. I can't speak to my competence, maybe I am grossly incompetent and those I work with are too.

I can say that I was well regarded in my profession before joining the gaming industry and I feel like the work I'm doing is significantly more complex than I was doing before, but that might be because I am lazy and incompetent.

That said, I'm pretty sure you know that Minecraft and AAA games are largely dissimilar.
It's called defecting if you committed that espionage for Russia or cooperated with their intelligence while there, which while not entirely impossible is not very likely either.
Right, so the idea is to separate the two experiences, like I said.

> almost no cross platform games from 2008 were heavily networked.

Aren't you forgetting something? Like every MMORPG in existence? Almost every player hosted multiplayer game like Warcraft 3 that were released in 2002? (the host can cheat because he is running the server but the other clients can't which is the important part)

Seriously. I don't understand how hard it is to just run the security sensitive parts on the server. It's not like running things on the client removes the need to communicate with a server. The amount of time the hacky solution wastes is significantly worse than doing it correctly and kills the game when it finally launches.
Not a psychiatrist, but I'm pretty skeptical of the approach of trying to sort things according to a few dimensions. I understand the appeal -- There is a reason why memes like sanguine vs melancholic or The Political Spectrum are popular -- but I don't see why it should be likely to cleave reality at its joints.

I'd naively think we're more likely to get a useful theory by trying to push a Predictive Processing approach too far for a while and then find a way to incorporate the signaling impact of hormones & ambient levels of neurotransmitters on various feedback loops.

The first tip works because : is a bash builtin that just returns 0, so all the comments are unused arguments. The copy/paste warning example is nice but I can't find ant other usecases for it.

The coprocess look very interesting, just yesterday I spent 2 hours trying setting up a bash script with 2 tasks:
1. open mupdf
2. recompile a pdf when sources change, and then send an update signal to mupdf

I ended up giving up because the signalling was too complex for such a simple idea and installed a latex plugin in vim.
I'm excited to try again with coprocesses!
What is the story for raytracing?

Considering they don't have enough manpower to compete with UE/Unity in raster, would it make sense going for full raytracing now?

That way, when next-next-gen hardware arrives in 2-3 years, they could be on the forefront of editors specialized in fully raytraced games.

It's weird that the dude you're talking to never expressed skepticism as to the provenance of the emails, yet you keep repeating this as if he is.

You seem to have a stock character of your own creation that you're responding to, some sort of cliched misogynist alt right conspiracies troll, instead of simply a skeptic who'd rather trust his own faculties to judge the source material over the opinions of ideological journo-activists.

Seriously, reread the thread.

In no way does he do this. Reread the thread.

> Even asking "what did you have for lunch" is better than asking nothing; the interviewer might start talking about whether the company pays for lunch, whether it's any good.

No, it's not. I'm pretty sure anyone who asked that in an interview would be bottom of the list, regardless of how I felt about their interview otherwise. It's flippant and shows a lack of care about what's going on.

Iv'e never been upset with someone for not asking questions. Interviews are tense and we do try to answer the most common questions before they are asked. If they have no questions, we extend and offer to email us later and we'll answer any questions they come up with later.

Stupid question affect the interview. Lack of questions doesn't.
They also lied about having end-to-end encryption. The awful security practices could be chalked up to incompetence but the fact that they lied has taken it too far, in my opinion. I too have deleted by Keybase account because of this.
I’ll suggest not for story,

You just shot down the idea in five words.

I have. This is why I know it's not on the level of Charlotte's Web in terms of story, let alone the Epic of Gilgamesh.

I’d humbly suggest that story isn’t a very strong reason for the majority of the best games ever made

Exactly.

games are good for other reasons, including but not limited to visuals and graphics, immersion, interaction, engagement, sound, mood, viral play, pushing boundaries on limited hardware, etc., etc.

Literally none of this is relevant to what the poster proposed.

So if I write some console APIs in my niche language (say, Haskell) and get that language building for said console..I can't share it with anyone? Or can I share it so long as the sharee also is NDA'd? (e.g. have a public stub repo where people with credentials can get free access to the private repo per NDA)
There is no need to secure the client because all the things the cheaters can mess with should be server side to begin with. DRM doesn't solve the problem. It only makes the problem more attractive because it lets you avoid the real solution. The end result is buggier games because the project manager can get away with shipping half assed crap.

I do not think that masks alone will be effective but in combination with other measures they will have an effect.

Ok, say most people fail to use masks to protect themselves (they take masks under their skin for example) but how does it affect protecting other people? Considering that many cases are first asymptomatic then wearing masks may considerably limit the spread.
Absolutely. I think we're all guilty of looking at famous people and believing they were born that way.

When in reality, as with everyone, the majority worked their asses off and honed their craft.

That it seemed effortless is a testiment to their practice, not their innate nature.

Free RAM has a huge influence of how much of the filesystem tree is cached in kernel. This is visible from just `time find`. It could just be a case of developer workstations going from e.g. 4 GB to 16 GB.
> Considering they don't have enough manpower to compete with UE/Unity in raster, would make sense going for full raytracing now?

I dont know how this makes sense.

Considering they have less manpower, they should make a more cutting edge renderer on unproven, unstable tech?

Full ray tracing is not going be any where near ubiquitous in 2-3 years, mark my words.

This is something you see in reverse with toddlers, they think you know everything they do (or at least that's been my experience with my own kids) so if they saw something cool then they assume that you saw it too. My kids have gone through stages of assuming they now know everyhing, too. Fun.

Would be interesting to see data on this. I agree that asking what did you have for lunch is silly. That said, what sort of lunches do folks do around here is not.

I suspect some of this is born from the idea that you want to be remembered. Asking a question can help anchor your existence to the people that interviewed you. Again, though, I'm sceptical without data. Feels you could argue this either way.
Long time Kate user, though I dropped KDE years back in favor of Fedora XFCE. If one isn't in KDE world, Kate's paint latency when alt-tabbing back to a Kate window is incredibly, painfully slow.
I don't like to be dismissive, but your suspicion isn't well-founded and is very likely based on little or no background research on the topic. If you had, you'd have found that SLAM and VSLAM as a subset is a well-defined category of computer with a strong mathematical background in optical flow and pattern matching on images[0]. You'd have found a number of iRobot patents still in their enforceable time period directly referencing the use of cameras in those algorithms[1][2]. You'd have found marketing materials describing how those systems work that directly correlates with the technology described in those patents[3]. That's based on no special previous knowledge of those materials on my part, just the top few results from a couple minutes of DDG and Google Scholar searches.

Implying that is just "a big name" that means "something far less interesting than it sounds" is an uninformed opinion. Plus, even [0], which is 15 years old directly refutes your comments about the effect of lighting. Lighting is helpful because it illuminates the scene that a camera is seeing, in the same way that it's easier to go on a night hike on during a full moon. We don't reference our position off the moon, it just makes it easier to see where we're walking.

Objective correctness is impossible to reach in a legal setting because it requires the fact finder to have unfettered access to all the facts, and for the law to be so strict that it cannot possibly be subject to interpretation. In the absence of these things, the adversarial system is the best system we know to approach the correct answer. Consequently, there is some error that we have to accept if we can't think of a better approach.

I'm not sure that the trials of either a wealthy defendant with deep pockets or an indigent defendant with a public defender significantly affect whether the finder of fact can obtain objective Truth with a capital T. The outcomes may indeed be different, but I also think it's orthogonal to the truth as well. They're more the result of the amount of resources you're willing or able to throw at a problem to make it go away.
Wow really cool! I'm wondering how much work it is to define the specific anchor/interest points on the SVG for the correct mapping to occur.

But I guess since "modern" illustrations are quite minimal, said work probably shouldn't take too long.

One really positive thing I have found for myself in the WFH life is that I am taking MUCH better care of myself. So far I have lost weight, started a bodyweight workout routine, which I do in between meetings/calls/other work, and have gained back 2 hours of my day by not taking transit into the city. That's 2 more hours every day that I get to relax, work on a personal project, hang out with my SO, or even crush out some work-related interest if I am feeling motivated. It has also been a fantastic motivator and resource for cooking — I can start dinner before my workday is over, cook myself lunch, meal plan...

I also pay thousands of dollars to live in a cool place, and now I am finally getting to enjoy it, and enjoy it with my SO.

At the end of the day, maybe I am less "productive", by normal standards, but maybe I didn't need to be in an office for 8+ hours every day to get the parts of my job done that need getting done.

There surely are parts of this that I want to change or can't wait to change, but at the end of the day I am grateful for the forcing function to working from home full-time.

There's always a chance of Freenet being the IBM Simon and Apple Newton and IPFS is the iPhone. Or, the VFX1 vs the Oculus. But no. While surely the tech has evolved from a shitty Java app as Freenet was, all those other examples had immediately obvious use cases and just needed the tech to catch up which it did.
I bought a new system with RTX 2070 Super and couldn't get any demos with raytracing to work acceptably in either Unreal or unity... The frame rates on super simple levels were maybe 10fps at best...

I was a little dismayed. It seems like AAA games are also not making a huge amount of use of it either. Despite the RTX name I don't know if it's really ready for prime time, at all.
