We have multiple issues:

* Delivery guys need to charge batteries a lot

* Not all batteries are safe and we have too many deadly fires

* Delivery guys go too fast

* Citibike batteries need to swapped in, rather than charged at the station if the utility (ConEd) allowed that

* Citibike has imbalance issues at rush hour, with empty/full stations, which they try to fix with vans and so called Angels, who are told to bike from A to B in exchange for points

My solution: plug Citibike stations into the grid, add more stations and bikes, require/encourage delivery guys to use Citibikes (which have a safer speed cap) at a substantial discount and also let them double as Angels.
I remember people discovering that the retina neurons were actually in a very non-common and much less connected geometry than most of our neurons, what meant that the numbers on that page were (an unknown number of) orders of magnitude smaller than reality.

But I have no idea what is known nowadays.
Clearly, I'm surprised there isn't a spam filter that detects this obvious attack.
As someone who lives near the rocky mountains, I will say the part about getting struck by lightning by a storm that's up to 10 miles away is quite accurate.

I was out riding my bike one afternoon in Chatfield State Park in Colorado when I looked up and noticed how quickly the weather changed. Clouds had rolled over the mountains in the west and I heard lightning strike in the distance.

In the same second, I saw electricity arc between my hands and the handle bars as my fingers froze for a second. I didn't feel any pain or shock, but I got out of the area real quick.

Tens of billions of dollars of investment specifically to keep up with Moore's Law.

It's basically akin to something like the Manhattan Project or the Apollo Program, just something initiated by private corporations rather than a government-directed investment program.
Or it might be literally invisible, a small black hole fits the observations.

Also it's predicted that a star comes with 1,500 AU of the sun every billion years or so, a star could have thrown things out of whack and left.
Yeah that's totally fair. I'm fine chalking this one up to me being too picky on a random Sunday night.
For Quest 3 specifically, "remote desktop into a computer" actually works surprisingly well if you 1) avoid the stock Meta software and use Steam Link instead, and 2) use wired connection to maximize bandwidth and minimize latency.

The second part needs some explaining. One undocumented feature of Quest 3 is that it supports (some) USB-C Ethernet adapters. There isn't really any UI for it that I know of; things just work so long as DHCP is there. This then gives you a direct wired 1GBps link to the PC, which Steam Link will happily utilize.

It only made sense to me if you expected an imminent strike on something nearby. Any other scenario I would think you would be better off getting off the X, or finding some bit of terrain that would make you not the highest thing around.

It also seems to be that people already understand getting off the X. Locally I'm aware of one rescue when someone got off the X and got cliffed out (no surprise given the terrain) and I'm aware of one fatality where the details were never reported but the location of his body only makes sense if he got off the X and got cliffed out--but on the other side where there's no cell service and the missing person's reports made no mention of satellite stuff. I'm not aware of any lighting deaths in the area, though. (Of course the real answer is don't go up there in lightning weather! The day he disappeared I had been considering a hike but considered the weather a no-go.)
I feel like this is a bit off. There have been things like Porsche phones, but those are so niche that I don't think they're really worth considering. They happened, but they haven't been a long-standing product. They were a cash grab where they licensed a brand.

Now, Hondas and Acuras are different products. You can say "oh, they're essentially the same" and if you truly believe that, I'll sell you a Core i3 processor for the price of a Core i7. Yea, they're essentially the same, but it's the differences that make one better than the other. The point is that the high end isn't about branding. The high end is about capability. Apple has shown that their iPhone will outsell any luxury-branded Android phone to rich people because some things are about capability, not a logo. Samsung's flagships will way outsell some luxury logo smartphone too. The high end here is really about devices with better capabilities and it allows companies with good hardware businesses (like ASUS and Lenovo) to build something in the Meta VR ecosystem.

It's also possibly a way for Meta to stop dumping Quest devices. They'd rather just own the ecosystem rather than doing the hardware. If they can get ASUS, Lenovo, and others to do the low-margin hardware work and pick up the tab for a lot of the marketing, that's a win for Meta. Maybe Meta simply backs out of hardware over the next 5 years if a nice third party hardware ecosystem arises.

But I think this is going to be tough with VR. When you're trying to make an immersive experience, you need a baseline of hardware. It's also easier when you know the hardware you're trying to target. Android development can be frustrating because there's so much variance in speed and capabilities. One of the reason gaming consoles exist is that targeting a small set of hardware/capabilities makes things easier. That's not to say that PC gaming doesn't exist, but it can be hard because gamers need to spend a lot of money on hardware and there's a variance in capabilities that you need to account for - and who you might simply exclude. With a phone, it's less of an immersive experience for most apps which are just displaying something. They might display it slower, the UX might be laggier, etc. but it works. VR can't be laggy.

In some ways, it feels like Meta is trying to become a game console company without having to subsidize the console. That would be big if they can pull it off. I guess in many ways this is what Steam pulled off on the PC - taking a 30% cut without having to subsidize any hardware. We'll see if Meta can do the same for VR.
I’m interested and have questions, but https://www.hotaisle.xyz/ doesn’t exactly provide a lot of answers.
I wouldn't say "hate" but in general I would have to agree. Besides the mildly contradictive list ("the lightning position" is bogus but "crouching" is recommended... er, isn't the lightning position kinda crouching?), I would say that all of the revelations of this article is exactly what I have been taught as a child... which was, cough, a long time ago. I have a hard time believing that any of the things "debunked" here are actually real.
It's a little ironic considering part of season 2 has some meta commentary on how hard it is to create animated shows. Guess the easy way is to indirectly outsource it to NK!
It's because of his continual praise of lisp that I wanted to check it out.

What I'm complaining about is that it's much harder to "check it out" than it perhaps could be.

At one point many years ago, I wanted to check out this new Python thing. It was so easy, I've been hooked ever since.
No, in fact, I don't.

This is (one of) my biggest gripes with Python. It's utterly inconsistent with its design, and library designers have taken that to mean they also can do anything they want, leaving NumPy vs Pandas to have completely different class vs object stylings for instance. I reach for Python these days only when there's no other option because I'm 100% sure I'll spend 50% more time in the debugger than using Ruby for a similar problem.
But why would I as a user want to use those flat apps in VR, when I already have a phone and a tablet?
For reference, I believe relatively rudimentary chatbots have been able to pass forms of the Turing Test for a while, while also being unable to do almost all the things humans can do. It turns out you can make a chatbot quite convincing for a very short conversation with someone you've never met over the internet[1]. I think there's a trend that fooling perception is significantly easier than having the right capabilities. Maybe with sufficiently advanced testing you can judge, but I don't think this is the case in general: in general, our thoughts may be significantly different than we can converse. One obvious example is simply people with disabilities (say a paraplegic) who can't talk at all (while having thoughts of their own): output capability need not necessarily reflect internal capability.

Also, take this more advanced example: if you built a sufficiently large lookup table (of course, you need (possibly human) intelligence to build it, and it would be of impractical size), you can build a chatbot completely indistinguishable from a human that nonetheless doesn't seem like it really is intelligent (or conscious for that matter). The only operations it would perform would be some sort of decoding of the input into an astronomically large number to retrieve from the lookup table, and then using some (possibly rudimentary) seeking apparatus to retrieve the content that corresponds to the input. Your input size can be arbitrarily large enabling arbitrarily long conversations. It seems that to judge intelligence we really need to examine the internals and look at their structure.

I have a hunch that our particular 'feeling of consciousness' stems from the massive interconnectivity of the brain. All sorts of neurons from around the brain have some activity all the time (I believe the brain's energy consumption doesn't vary greatly with activity, so we use it), and whatever we perceive goes through an enormous number of interconnected neurons (representing concepts, impressions, ideas, etc.); unlike typical CPU-based algorithms that process a somewhat large number (potentially 100s of millions) of steps sequentially. My intuition does seem to pair with modern neural architectures (i.e. they could have some consciousness?), but I really don't know how we could do this sort of judgement before understanding better the details of the brain and other properties of cognition. I think this is a very important research area, and I'm not sure we have enough people working on it or using the correct tools (it relies heavily on logic, philosophy and metaphysical arguments; as well as require personal insight from being conscious :) ).

Are digital nomads just remote workers? Because I was assuming that they are workers that move significant distances somewhat frequently unrelated to job switching.

But I wouldn't be surprised to confirm that my gut isn't correct.
When everyone holds the data you don't have an edge. They had dedicated users who kept generating new and relevant "content" for a for-profit company with an implied agreement to keep it accessible and discoverable, but they decided to kick them off the platform and try to take hold of what their users had effectively created. That didn't exactly work.
Yeah we recently had a load pay something like $1.5m to jump up the queue to transit the canal. Not even a "guaranteed transit by X" but just jumping up the line! Which at the time was something like a month and a half long, IIRC.

Being a specialized load (read, unusual cargo, not containerized, on a barge) I doubt transloading to rail and back onto a ship on the other side would have been practical in our case but for other cargoes? It might be an attractive alternative.

Are they capable of selling hardware loss leaders indefinitely? If so, can they do it at a scale that matches the company's digital presence? The Google Daydream headset sitting on my shelf is skeptical.

Regardless of whether they can sell the hardware at a loss forever, they probably won't need to.

Third-party hardware is engineering labor that Meta doesn't have to pay for. In fact, it's engineering labor that will pay Meta through royalties. Cost-cutting measures developed by those third parties can easily be copied by Meta's own product, reducing the cost of future versions of the hardware. Cheaper options in the marketplace also help Meta gain market penetration without their own hardware developing a reputation for poor quality.

After a couple generations, vendor lock-in will start to set in, and they'll be able to charge more without losing customers. The aforementioned cost-cutting techniques start to pile up, too.

The potential trouble with $ (even in single-line mode) is that it matches the end of a string BOTH with AND without a newline at the end. If you're using it to ensure the string has no newline before doing something with it, this can lead to trouble.

$ python3 -c 'import re; print("yes" if re.search(r"^foo$", "foo") else "no")'
yes

$ python3 -c 'import re; print("yes" if re.search(r"^foo$", "foo\n") else "no")'
yes

$ python3 -c 'import re; print("yes" if re.search(r"\Afoo\Z", "foo") else "no")'
yes

$ python3 -c 'import re; print("yes" if re.search(r"\Afoo\Z", "foo\n") else "no")'
no

Even if the newline is not problematic, using \A and \Z makes your intentions clearer to the reader, especially if you add re.X and place comments into the pattern.

Asides:

1. Based on syntax, you appear to be testing with python2.

2. With python, re.match is implicitly anchored to the start, so the ^ is redundant. Use re.search or omit the ^.

Another helpful exercise: sort your tasks by payoff horizon, from immediate need to long term investments.

Immediate needs like invoices and bill pay, resolving service disruptions and support tickets can be the loudest contenders for your time. Make sure you set aside some time to build tools to address the root cause of your biggest time wasters: automate repeated tasks, build diagnostic tools to speed up support responses, restructure systems to prevent bugs which happen repeatedly. Once you've matured your operations, invest time in documenting them so you can sell the business (or delegate to staff.)

Don't allow short term demands to derail your progress toward accomplishments that will make life better in the long run.
It didn't use to - for various reasons, evaluator inherited from CMU CL had bitrotted at one point, and for many years every form more complex than essentially single function call resulted in compilation.

Few years ago there was work to fix the evaluator and now EVAL has limited evaluation back.
The US did not require any data crunching from IBM or anyone else to genocide the Indians.

The entire line of thought is straight up propaganda from weird Christians who have a really weird cult belief that some id number is the mark of the beast and saw a great opportunity to lie about the holocaust (plenty of jews were murdered using no better data than "Wilhelm says he saw them praying last Saturday").

You can see the same stupidity in the talking point from 2nd amendment maximalists that the jews were only genocided because they gave up rights to own guns, or something to that effect, as if a population experiencing genocide would have qualms about illegal firearms.

Without a thorough analysis by real engineers my interpretation of this statement is "DRAM marketers can print anything they want on the sticker".

Really wonder, if this kind of spam is the perfect application for an LLM based agent.
False. "$" does NOT mean end-of-string in Perl, Python, PHP, Ruby, Java, or .NET. In particular, a trailing newline (at least) is accepted in those languages.

A $ does mean end-of-string in Javascript, POSIX, Rust (if using its usual package), and Go.

I'm working with the OpenSSF best practices working group to create some guidance on this stuff. It's a very common misconception. Stay tuned.

If anyone knows of vulnerabilities caused by thus, let me know.

I assume there are sort of natural skill ceilings but if you practice with more difficult scenarios and really push yourself you'd be amazed at what you can do. I've got an essential tremor[1] and I usually play on Expert+ for the vanilla tracks which is usually do-able for me.

1. On that note - my tremor does hurt me here too but unlike twitch shooters (which I loved before my tremor got bad) and things like guitar hero (which require comparatively precise movement) beat saber is usually pretty forgiving about precision of placement and angles - so long as your rhythm is correct you can go pretty far with it.
How is a behavior tree different from a decision tree? Is there a subtle difference I am missing?

Sure, though I've mentioned a few times in this thread now that the thing that bothers me more than CPU optimizations is not taking into account latency, particularly when hitting the network, and I think focusing on that will generally pay higher dividends than trying to optimize for processing.

CPUs are ridiculously fast now, and compilers are really really good now too. I'm not going to say that processing speed is a "solved" problem, but I am going to say that in a lot of performance-related cases the CPU processing is probably not your problem. I will admit that this kind of pokes holes in my previous response, because introducing more machines into the mix will almost certainly increase latency, but I think it more or less holds depending on context.

But I think it really is a matter of nuance, which you hinted at. If I'm making an admin screen that's going to have like a dozen users max, then a slow, crappy solution is probably fine; the requests will be served fast enough to where no one will notice anyway, and you can probably even get away with the cheapest machine/VM. If I'm making an FPS game that has 100,000 concurrent users, then it almost certainly will be beneficial to squeeze out as much performance out of the machine as possible, both CPU and latency-wise.

But as I keep repeating everywhere, you have to measure. You cannot assume that your intuition is going to be right, particularly at-scale.
Yeah, that's very valuable information to people trying to solve problems.

But "old content" is maybe not so valuable for engagement-based revenue.

If Reddit wanted to restore the deleted stuff, I suspect that they still have copies of it.

If user sentiment was the barrier to restoring the deleted (say, in non-"sensitive" subs), then waiting until after IPO seems a good idea, so maybe we'll see that now.
While not reading in the visual sense, the smartphone is a transformative device for audiobooks and podcasts.

When a publisher provided a choice between a PDF of a book and a physical copy, I would usually ask for the PDF, because I didn’t want my house to fill up with books that I might end up not reading. . . . now I encounter nearly every written work, regardless of its length, quality, and difficulty, on the small screen of my iPhone.

That sounds awful.
