As others have pointed out, lidar doesn't denote capability.

1d lidars that have a range of 8 meters indoors are quite cheap <$15 volume.

"2d" lidar, that is one measuring one plane's depth, are generally a lost more costly. Not only that they are bigger and eat more power. again indoor only.

3d lidars are more expensive still, and if you want it to work outdoors, even more.

The news reporter doesn't tell you what to think, they do the research - talk to competitors' CEOs, talk to independent experts, bring up that lawsuit and interview leading attorneys in the field, research prior comments and actions, ask followup questions to the CEO of the corporation who issued the press release, etc etc - and then share it with you.

No one has time to do that themself, and the CEOs, attorneys, experts, etc. won't return your calls anyway (they can't return everyone's calls).

Opinion writers are the one who tell you what to think. IMHO, few of them are better than blogger.
You also have to only buy things available purely on that system from people you are certain don’t collaborate with the government. If all of those assumptions aren’t true, your activity can be tracked with increasing precision and the authorities will see local transactions which you can’t explain otherwise and demand explanations.

The schemes Zcash and Monero use have never been tested at scale with a sophisticated adversary. The statistical methods used are probably fine for keeping your friends from knowing what you buy but it’s less clear that a government which can observe network traffic and receive KYC data from compliant merchants or compromised devices won’t be able to rule out some of the decoys over time, and since it’s a blockchain you’re gambling that this will hold true forever.
But the guidelines do.

I've seen some apps recently move to only having icons and no text label. I think Paint in Windows 11 is an example. I really dislike this as for an app I'm not using every day it takes me extra time to decipher the icon. And on desktops where screens keep getting larger I have the extra real estate for the app to be clearer.

This is connected to another UX trend I don't understand of dumbing down interfaces because too many options are "too distracting." Probably not the best forum to ask this but has anyone ever stopped using an app because they got distracted by the menu?
Why not exclude the .git directory from being synced, if you're not going to be committing on your mobile devices? This is what I do.
> it doesn't make economic sense

It does, in the other parts of the world, where there are cars being made that exist outside of the luxury market.

You can still get a Nissan Versa for $16k. Adjusted for inflation, that's only $7k, in 1990, which is cheaper than a Ford Escort from 1990, and 35% more horsepower.

The problem is that people's standards are ridiculous.
On top of that, it's easy to click the "hide" link under a story title, and that leaves more room on the front page for stories I might actually want to read, without having to dig deep into successive pages of stories.

As a counter point, GitHub has remained great for longer than expected, and has arguably improved since being bought by Microsoft.

I'm sorry, can you explain what is "right wing" about this? It sounds like you a grasping for a label because you don't like Shellenberger's reporting.

For example from the article: "In Germany, a court ordered the American writer C.J. Hopkins to either go to jail or pay 3,600 Euros for comparing the covid lockdowns to the Nazis."

If I think this is wrong, does that make me "right wing"? Why then is discourse not permissible according to you? I guess my other question for you is, are these definitions accurate?

Hate speech = Speech that I or an institution doesn't like

Right wing = People that I or an institution doesn't like

Jaynes's timeline, anyway, was badly messed up. The notion of independent brain half-selves has been debunked, although brain function localized to certain places is real. It is clear that, if indeed people at that time experienced life as he describes, then by the time we got writing not everybody did. We don't need to depend on any notion of changing neuroanatomy; brain function is entirely plastic enough without such an assumption.

I quizzed an ancient-Greek scholar about Jaynes, and his story about evolution of Greek language. He said there is no such phenomenon in Attic Greek, and Jaynes had confabulated it. Such confabulations have long been an occupational hazard of Classics scholarship. Modern statistical methods have proved necessary to banish them.

Yes this is in every city and state.
> underestimating just how many different materials/fixtures/fittings get installed in a house

This is one of the reasons why I would believe Lowes or Home Depot or another construction supply place would 52 such a piece of software. They have those zillions of "something" that get installed, and the lumber. They already know what all those people buy.

At least for a construction company: pick a general house, gives you adaptations for common landscapes, choose interior finishing(s) / style(s), gives you plans (with adaptations), already has them approved for your area (with variants), gives you parts list, gives you plumbing/wiring, gives you button to put it all in your "cart," drive to store, pick up house worth of stuff, Lowes/Home Depot make a quick $50k-100k or so.

If you build a development, you say, give me 10 of that. Build it again, say I'd like my old order.

>>Here we have designed an automated system by using a Convolutional Neural Network which can detect whether a person has any intention to commit any crime or not. Here we proposed a new method that can identify criminal intentions or violent behavior of any person before executing crimes more efficiently by using very little data on facial expressions before executing a crime or any violent tasks.<<.

Anger may precede violent actions, but is in no way evidence of any type of intent.

>>Violent Facial Expression<<

Facial Expression is not violence, it is a signal of emotional state.

if facial expression is violence, there would be a lot of tech users in jail.

Interesting to see the perspectives from early hacking pioneers. Seems like some things haven't changed much - debates over ethics of unauthorized access, whether it's criminal, free speech implications, etc. But more nuance now as hacking's gone more mainstream.

Biggest change is probably threat models. In 1990 main concern was individuals hacking systems for challenge, curiosity, etc. Today it's nation-states and organized crime using hacking for financial gain, espionage, even kinetic attacks.

Other change is commercialization/professionalization of hacking. Now huge industry around cybersecurity, ethical hacking, bug bounties. Hacking skills lead to lucrative careers, not just hobby or activism.

More diversity today too - no longer just male techies. But part of cyberpunk spirit remains, even as hacking's become bigger business and political issue.
I have seen zero evidence of this; but if it's true I would love to learn more. The real action is in side channel vulnerabilities bypassing all manner of protections.
Half a day to get something running that's a "one off" for you is insane. With a compiled language project, I'd download a binary. In Python, I need to reproduce the developer's setup. And I've yet to find two different Python projects where the official build instructions are compatible -- each one recommends a different environment virtualizer, a different runtime, different settings, and different C libraries that aren't part of the virtualized environment.

I think a larger factor is that there are plenty of us folks with ADHD that didn't have traumatic childhood experiences and have had therapy in the past (with no impact on our ADHD tendancies).

If the comment was intended to say that some people may have ADHD like symptoms due to childhood trauma and that might be resolved by working that out it was quite poorly worded - to me at least it read as coding all ADHD as treatable by therapy and environmentally caused and that is simply untrue for me. There may be a certain amount of defensiveness in our community in particular because for a long time ADHD was written off as behavioral issue causing laziness rather than being treated as a true neurologically divergent condition. I was diagnosed about twenty two years ago and I've seen a lot of FUD around my condition and the ineffectiveness of ritalin and other stimulants - they very well may have been mis-prescribed in the 90s but for a decent chunk of us it has been highly impactful.

> What does 1.5 billion years mean if time ran slower?

That's a good question and the Wikipedia has an oversimplified answer here: https://en.wikipedia.org/wiki/Cosmic_time

Basically, what it boils down to is imagine a clock traveling at the same rate of expansion as the universe (the Hubble flow). Now further imagine that clock ticks once per year. The phrase "1.5 billions years after the Big Bang" means such a clock will have ticked 1.5 billion times. It's the only way you can do time that makes any kind of sense, when you think about it, since time is literally relative.

Relativity is what makes things weird, because what you're really wondering is if we somehow had a clock on earth that also ticked once per year (standard years like we measure today), how many ticks would it have ticked after the aforementioned clock ticked 1.5 billion times? Such an "earth clock" will have ticked more times, due to the difference in time dilation. If you're still following along, then that means when we say such a clock I first described, the cosmic clock, has ticked 13.8 billion times, this supposed earth-bound clock will have ticked a near infinite amount of time - meaning, from our perspective, the Big Bang singularity is an infinite amount of our time in the past, even though our cosmic clock will have only ticked 13.8 billion times since the event!

Welcome to relativity!

Note this is the same issue with approaching the singularity of a black hole. The clock approaching the singularity will reach the singularity in the time its gravitational acceleration indicates and will proceed normally to the singularity. From outside of the black hole (you have to imagine being able to make this observation) you will never see the object reach the singularity. Such an event is always in that observer's future.

If you think this is bollocks - it's GR's time paradox and is the result of a singularity, which is a strong sign that things have gone awry. BUT - we do know time dilation exists and we know GR works well right up to the point of the actual singularity so while from our perspective the object reaching the singularity probably isn't infinitely in our future, it's very, very far in our future. Likewise, for the Big Bang singularity even though the cosmic clock ticked off 13.8 billion years, from our perspective the event was much further back in time than that.

Weird stuff!
I do often see people asking why they've been downvoted (and seem genuinely confused), but I don't think it's the right move to require at least one explanation reply.

I'm reminded of the xdcd "someone is wrong on the internet!" comment. I'm starting to get to the point where I don't feel like arguing or even explaining things; I just want to downvote, move on, and hope my moderation contribution has made the shape of the thread more useful to people.

If I had to explain my downvotes every time, I'd hardly ever bother, and I suspect that's true for most people. A forum where no one wants to take the time to moderate is not going to be a healthy place.
linux, qemu, postgres and many other projects written by "C developers" use and rely on fwrapv, fno-strict-aliasing and others.
The Japanese version looks quite a bit more grounded in naturalism than the Chinese version, or at least TFA's translation does (i.e. August 28–September 1 天地始粛 vs 天地始肅 [1]). "Heat starts to die down" is not exactly precise but better than "Heaven and Earth begin to Withdraw" and "Cotton flowers bloom" is definitely a lot better than "Eagles worship the Birds".

I'm not the GP but I definitely want a calendar made up of details like this, regardless of it's literary quality.

I'd be curious to know the legality here more concretely. My understanding is that although a lot of it is not enforced, it is technically illegal to sell or publicly display images of another person's likeness without their consent.

AFAIK An artist can draw whatever they want for personal use, and this is where I feel the distinction on whether or not an AI produced image is considered personal use or a traded good becomes critically relevant.

> Sometimes I see papers with 2,000 citations and I wonder: how many of those are dis/agreeing with the paper.

One example of an author that is very influential, despite causing a lot of disagreement (even in more than one discipline) is Noam Chomsky, who is also the most cited person alive, and the second most cited person in recorded history after Aristotle. His views about generative grammar are in part revolutionary, in part plain wrong; your assessment of his views about the Palestine conflict and U.S. foreign politics will largely depend on your political leanings; and his contribution to formal language theory is fundamental regardless of your leanings (Chomsky hierarchy; Chomsky Normal Form).

I remember looking for a Ku Band Phased array for a large drone. Cheapest I could find from a reputable company was $16k.

Not one dime of RDOF was paid. And knowing how the last RDOF equivalent worked they had every right to apply and get awarded (delivery is dubious though except in less densely populated areas). They don't seem to fake speed tests too unlike the US Telco they are partnering with for direct to cell.

The flat design means way more sats per launch. And that means you're mass rather than volume limited. It's a big difference maker since theres no central stand. Check out the SpaceX OneWeb launch as a comparison.

Iridium links are microwave. SpaceX is a laser. The tech is licensed. It's not just bit rate. And I don't think you can do 10 to 20 up on Iridium. is it possible? Is it possible at say Viasat Maritime prices? Iridium to carry drone video and/or Netflix at $10k to $20k p/m?

Is it financially viable? Time will tell. Some space economist claims SpaceX twisted the arm of the Feds for over a billion in Ukraine. I don't believe him
I’ve been applying DIY 20% ascorbic acid solution on my face for a few weeks, and am seeing some benefits already. Photoaging and spots seem to revert a bit, and there is definitely some lightening (as expected [1]). According to some Reddit posts, it takes a few months until the improved collagen synthesis becomes noticeable.

Vitamin C serums are quite expensive because ascorbic acid oxidizes quickly, and other forms have to be used instead. But if you mix ascorbic acid with distilled water yourself, every few days, you get a very cheap and probably more potent alternative. I put it in a sprayer bottle, keep it in the fridge, and spray my face in the morning. I haven’t found studies on the ideal concentration so far, but consensus on Reddit is that anything between 10 and 20% is ideal for collagen synthesis. 20% is too harsh for some.

The vendor? Ha! Let me laugh.

Would this have tripped on some obscure device specific to Dell laptops, sure, I would understand. (like their blimey fingerprint reader). But this is the standard NVMe controller on this generation of intel CPUs. The drivers are common for _most intel platforms_: the Intel Rapid Storage Technology.

As somebody else pointed out, Linux fares much better in this space. All devices are properly recognized out of the box, including this bog-standard NVMe controller.
I remember my old games fondly. There was just a post this week about Tempest using long-term exposures, and found it fascinating.

The thing about music though... it is people communicating with people---stories. Sometimes it able to pull our "heart strings." Ain't no program gonna do that, or at least very few of them. They don't even try for the most part.

A video game is pretty neat of course, but it's typically like an electronic version of the game of Life or Monopoly, maybe a shoot-em-up. Fun for an evening but not moving anyone to tears. To some extent that's a choice of the content producers.

IAH: Internet War
Hey people!

I wanted to share the news with this community about my upcoming video game about AI, Hackers, and the web.

The game I am developing is an RTS (Real Time Strategy) in its roots, but it has a multiplayer component that requires programming skills if you want to operate your bots. In this game, internet cyberwarfare is portrayed in a way that all actors on the internet are Bots.

Why i think this is something that could be interesting for this community is that multiplayer is algorithmic and can only be accessed by programmers; you are supposed to write your own AI in any language, exploit other players in a sandbox, and win.

The hook is that the end goal is to create eSports where hackers and programmers will battle each other in sponsored tournaments.

Feel free to comment or ask further questions.
