Nix is a much more general purpose tool than asdf.

Nix can also be used to build Docker images, VM images, or configure a NixOS system. Nix's packages can also be run without being installed.

Specifically for setting up a development environment? As sibling pointed out, nix shells can provide native libraries.

With nix shell, it's also possible to have the shell be strictly 'pure', in that the shell's environment will only be what's declared in the Nix shell. Having that ensures that you're not relying on environment variables you set elsewhere, or stuff you installed elsewhere.
The end of an era, a rather pedantic and overdrawn one.
I wonder whether they've considered the possibility of open-sourcing their apps and backend. Perhaps this is just Pollyannaism, but I tend to believe that workers' rights and open-source are the perfect match in a market like ridesharing. "Just goodenough" open source solutions have difficulty breaking through in consumer software (e.g. the mythical "year of the linux desktop"), but in a market like ridesharing, worker coordination could easily provide the push to critical mass.

That quote does not disagree with OP at all. It says that the aviation industry itself determined that they should not be "left to their own devices" (OP's words) and asked for federal regulation.
Awesome, predicting words from fMRI has been around for a while and visual cortex can be mapped well.

That said, and coming from a background in neuroimaging 20 years ago, what’s the applicability? MRI hasn’t gotten that much more cost effective for more widespread uses. Magnets are expensive.

She's still pushing the "Elon will turn it into an everything app" angle, and talking about how in the future it'll 10x and what not, which is pure Cathie Woods, but it seems more absurd by the day.

Elon, by his very own admission only a day ago, is currently caught in a catch-22 or a chicken-and-egg situation if you will. He's losing money fast, and the only viable path to revenue is getting ads back. He can't get ads back without significant investment, but he can't do significant investment without ads. No one would risk investing or loaning to Twitter in its current state, either.

And until this catch-22 is resolved, Elon can't innovate. He has no means to turn this into an "everything app". It's barely the app it was. Unless maybe he sells $10 billion more in Tesla stock and throws it down the Twitter drain. And I highly doubt he'd want that, or Woods herself would encourage that. So it's all just empty PR talk not to scare her investors.

Twitter is so lucky that Meta has only 10 developers working on Threads. It means they're not trying. They have thousands of developers on Facebook just tweaking things in the Android app that no one sees. If Zuckerberg gets serious about keeping up velocity on Threads, then Twitter will be left behind in the dust.

Not to mention the other competitors are also not looking bad, BlueSky in particular (over a million users on a closed beta).
No AI we currently have can do this.
Thank you for being vulnerable (to the the extent that you were being) with this post.

My two cents, I deeply agree that "everything has a cost" but I don't find that most unambitious people make a conscious trade off.

Most unambitious people I know aren't doing anything with the time and energy they are "saving". They are just kinda passing/wasting it on things that don't satisfy them deeply.

That's different than someone making a conscious decision (eg not taking the most demanding job in order to have time w the family)

The other thing unambitious people often miss is that working hardcore can be fun and energizing in its own right and it can develop you as a person holistically.

I don't think many ambitious people work hard despite hating it every second. I think they rather enjoy it and benefit from it (similar to someone who likes exercise). At least that's been my experience and perception.
Are you planning on selling it?
This is SO COOL. I'd guess (I did analysis for an fMRI lab for a year so I'm not a pro but not totally talking out of my orifice) that detecting images like this is among the easier things you could do (it probably wouldn't be so easy to do things like "guess the words I'm thinking of") and I suspect other sensory stuff might be harder but I have little knowledge there.

One of the biggest issues with any attempt to extract information from an fMRI scan is resolution, both spatial and temporal - this study used 1.8mm voxels which is a TON of neurons (also recall that fMRIs scan blood flow, not neuron activity - we just count on those things being correlated). Temporally, fMRI sample frequency are often <1hz. I didn't see that they mentioned a specific frequency, but they showed images to the subject for 3 seconds at a time so I'd guess that's designed to ensure you get a least a frame or three while the subject is looking at the image. You can sort of trade voxel size for sample frequency - so you can get more voxels, or more samples, but not both. So detecting things that happen quickly (like, say, moving images or speech) would probably be quite hard (even if you could design an ai thingey that could do it, getting the raw data at the resolution you'd need is not currently possible with existing scanners)

Also, not all brain functions are as clearly localized as vision - the visual cortex areas in the back of the brain map pretty directly to certain kinds of visual stimulus, while other kinds of stimulus and activity are much less localize (there isn't a clear "lighting up" of an area). You can get better resolution if you only scan part of the brain (i.e. the visual cortex) (I don't know if that's what they did for this study), but that's obviously only useful for activity happening in a small part of the brain.

ANYWAY SO COOL!!! I wonder if you could use this to draw people's faces with a subject who is imagining looking at a face? fMRI police sketch? How do brains even work!?
That's right. The post set off the flamewar detector.
That is interesting. The high desert is my current location so it's "only" 105 but with the same low humidity. I find that a sunshade massively reduced any issues that I had with the idleness of the vehicle. But I'll give you that the heat is horrible.

I suppose my rebuttal is: how many months do you feel like tint is necessary? I grew up with routinely high temps (100+, in an area with high humidity). In college our first few weeks were normally 100+, and we did walk to class. I normally would come back with swamp ass and a back covered in sweat. People absolutely can live in these conditions. I just don't think we can remove the human element of it. It's hot, we are going to sweat. It feels like we are trying to control an element of human nature that cannot be controlled.

Edit: I appreciate the reply. Apologies if I sound snarky (as another commenter apparently thinks). It's truly just that the only people I know with tinted windows have been controlling and manipulative. The experiences I get on the road do not help my anecdotal stereotypes.

I'll try to explain their argument under the assumption handles were convincingly fake, e.g. there wasn't a heuristic to tell real and fake handles apart.

The underlying protocol (U2F or CTAP) will send all received handles to the separate hardware authenticator. Some of these may be real, some may be fake. Some may have been created by other keys.

There is a process to convert correct handles to a correct private key inside the hardware. This _should_ have some sort of integrity to prevent taking incorrect handles and creating garbage private keys as well - those will fail, but the user experience will be sub-par and there are always cryptographic concerns about processing attacker-chosen data.

So when I make the gesture to authenticate, the valid private key which came from a correct handle is used to sign a response message to the authentication request. All the fake handles and those created by other keys would be ignored.

So if the handles are convincingly fake, the web site would be the only one which would know which were real or fake (so that it can still offer proper user self-service management). An individual piece of hardware would know which were real handles that it created. An attacker wouldn't know if they were all fake.
You didn't piss anyone off at HN. The post set off the flamewar detector, which is a software penalty that causes a thread to fall in rank when the discussion is overheated. That's the only thing that happened, and it wouldn't have affected your karma in any way. The only thing that makes karma go down is downvoting on comments. (Submissions don't have downvoting, only flags, and flags don't affect karma.)

I checked the logs and your karma has never been 4997. The most it has ever been is 4812. It went to 4811 after someone downvoted https://news.ycombinator.com/item?id=36762833.

Your karma was 4797 when you submitted the post, though—most likely you misremembered 4797 as 4997, which is an easy enough mistake to make.
> we’ve built a massive surveillance apparatus and also the misinformation ecosystem that grew out of Facebook is screwing up politics around the world.

I'm also concerned about the misinformation ecosystem, but why is the surveillance apparatus a primary cause? I'd say the primary causes are a lack of content moderation and the incentives that the platform creates by putting likes as the main way that ideas spread.

This is a different problem, because the TSP is about reaching every point in the shortest distance, but in this case you can't just hit every point in any order you want. Each rider is going to want a ride at different times, and each rider is going to make their request at different times, and multiple drivers are going to be available at different times.

You are optimizing for least amount of time riders have to wait, not just for shortest distance driven.
There is a particular notion of "radix economy" which takes into account both the length of a number compared to its size and the informational complexity of more symbols. It doesn't really have anything to do with data storage though. If you could create a device to store 1000 10-bits (10its?) for exactly the same cost as one that stores 1000 3-bits you'd obviously pick the base 10 one, no matter what radix economy says.
US economic performance is all the more OP if you take into account that it's a huge country of 350m people and has a diversified economic base.

For a tiny banking nation or petrostate to be rich is unsurprising.

But when it's half a continent, the world really ought to take out their notebooks and go into full copycat mode - at least as far as economic policy and attitudes are concerned.
Since you don’t have a sense of smell, have you wondered if perhaps one of your other senses is enhanced in some way from using the spare brain matter? Do you have synesthesia?
A cab service with unknown, frequently updated nodes where edge weights - driving distance from last drop to next pickup- can vary, would qualify as pretty bad version of TSP.

You can come up with a good enough solution but it’s not “solved”.

This “good enough” solution starts to break down whenever there is a huge concentration of drivers in a location. If this weren’t the case, ride shares wouldn’t have had to add a cancellation fee and hidden destinations from drivers.
I’m not counting it out. Lots of people want an alternative to Twitter since Musk has alienated a significant percentage of users. The Threads app though sucks really bad. It is a very bad implementation and it’s embarrassing that Facebook launched such a bad app.
I think it's again a modern secular assumption that your kids move out and there's some sort of deep emptiness.

The traditional expectation is that your kids move out to be married and bless you with grandchildren, not to abandon you to rot.
Why is that boring?
I'm not sure I see how one is easier than the other. In studies where they find that wine, say, causes cancer, they aren't looking at some molecular chain of events, they're simply doing a large (hopefully) study and looking for correlations, while attempting (hopefully) to factor out confounding variables and incorrect direction of causation.

In some of those studies, the wine drinkers get more cancer. Red dot to the right. In some they get less. Red dot to the left.
Depends on how fast a typist he is.
Dataframes are vectors of vectors. And functions on them may return either vec<scalar>, or vec<vec<scalar>>, and in a chain of such operations it's easy to lose track of what you have.

Of course every delay is a potential interruption to focus which costs way, way more than the delay itself, so much so it's not worth calculating the actual delay's 'lost time'.

In fact even a momentary delay (my macbook now seems to often stutter for 2-3 seconds switching spaces) is an opportunity for your focus to drift (why is this damn thing so slow, I should get a new machine, actually, I should lookup the latest thinkpad, maybe I can tune memory use in the meantime, how do you tune macos memory, can you even?, etc ...).
I can't find much detail in that marketing page. What makes it IoT? Does it do some low energy protocol like zigbee/thread/lora etc? It appears to be just bt/wifi.
What did I reference? It was a very short message, so probably you saw what you wanted to see, or what you could see. But all I said is that a lot of modern studies are noise like that, and it's actively harmful, and the process which produces these studies should be modified.

Modern researchers have insane incentives to churn out papers based on superficial or questionable data, without isolating variables. The result is predictably noise. Or even worse, noise shaped by cultural bias and prejudice, which has been a long term problem with the scientific method, because in the end, we can talk about facts and evidence and data, but the judge jury and executioner on what is a fact, evidence and data are people, and people are always subjective by definition. The best we can hope is to all be subjective in the same way, hoping our shared subjectivity is more objective taken together. That doesn't always hold up.
Interesting.

I have experienced "devs changed something and it broke reporting" more times than I count. Typically the reason boils down to 1) they don't care, 2) their management doesn't care. That has always felt like an insurmountable cultural problem, but I do wonder, if a bot posted a PR comment on breaking changes before they got deployed, might that move the needle, just a little?
Ground delivery drones are making great strides. They're not uncommon in larger restaurants where I live, and they're also being used in the hotel industry for making deliveries from the front desk to someone's room. I expect we'll be seeing street delivery drones like this soon as well in very high density urban areas.

Aerial drone delivery however ends up requiring additional infrastructure and is far too expensive for what it's trying to accomplish, particularly because of the small payload requirements. Maybe that will change in the near future, but I still think we're a long way away.

Thanks for posting clarifications and disputations, seriously. I naively thought all the PPP business meant something that I’ve since learned it does not.
Agree. Nobody needs to do that. And I am not complaining.

I am simply showing that it's easy to get to that ballpark number with relatively generic car owners behavior.
> The CPI only includes OER (owner equivalent rent), not housing prices. OER is also a lagging indicator due to it being calculated on current rental expenses, not market rate rents (eg. when people move and their rental expenses get adjusted for the market).

And that's fine, because the CPI is for the whole country. Not everyone is a renter looking for a place right now. Some people do indeed have houses and therefore their housing costs are locked in perpetuity. If you take nominal wages, and deflate that using cpi-with-market-rents, that would indeed more accurately describe the plight of someone who's renting, compared to normal cpi. However, it would also make it the situation look worse than it is for someone who owns their home, because their housing costs are essentially fixed. You might empathize more with the former and think their plight deserves more attention. That's fine, but the specific claim being made was for the economy/country as a whole, not for a specific demographic.

>Except cameras don’t shoot people

Obvious photography jokes aside, this seems like a case of bad police training, or excessive guns in the US causing police to need to 'shoot before being shot'.

If someone is looking a bit dodgy standing outside a kindergarten, I'd absolutely want "predictive policing" to go have a chat to the guy. May just be a case of someone excessively caffeinated waiting for their kid, in which case no foul.

However the appearance of the police keeping on top of things deters others from committing actual crimes. I'd rather police prevent abductions than solve them.
A trit is 0,1,2, no? Tri-state.
I'm not sure I understand what exactly the advice is. Is it just "don't be afraid to do something risky, as you might regret not going for it"? That doesn't seem helpful to me, I can easily regret doing something I really wanted to do before.

"I can be penniless or I can be bitter." Why not both? If I try something risky and fail and end up penniless, I'll be penniless and bitter.

Sysadm here as well, been using vi since the '80s. A year or so ago I threw away all my custom vimrc and went with (nearly) bone stock LunarVim, and have really enjoyed getting off the treadmill of maintaining a custom vim setup. Partly because of the 100s of machines issue, partly because of managing plugins and interactions between them. I program maybe 5% of the time, so the stuff I do to make it IDE-like often isn't worth maintaining for that 5% time, so I often end up with partially working plugins or whatnot.

LunarVIM has been a bit tricky, mostly related to upgrades around LunarVIM, usually neovim updates. But, the capabilities of having Language Server in vim have been so refreshing! Particularly when working with Python 2 code to bring it up to Python 3, pretty much just follow what Language Server says.

When it gets right down to it, there are only a couple little tweaks from my old setup I want to carry over, everything else I want to go back to using defaults (places where I've diverged my own functionality) and stop pushing around a poorly maintained manual config that gives me 10% of what Lunar or similar gives.
Yes, there are plenty updates from my last submission.
For example, we've supported 10+ more chatbos, refined the UI, supported more layout styles etc.
Ride share companies are surviving so it’s clear that some good enough solutions do exist.

There’s a difference between the algorithms ride shares have to use and the heuristic based solution for 85.6k cities.

The graph for ride shares is constantly changing as passengers request rides from random starting points to random destinations.

This version of TSP is much harder to solve.
I don’t understand why? What’s ublox addition to it? Antenna design?
Oh man, a friend and I were thinking of building out a FOSS Uber clone for this exact purpose. Would allow a bunch of smaller regional Ubers to exist.

Couldn't get funding and I don't have free time to write that much code.

Hope these folks are able to succeed.

FOSS is a great path for workers to seize the means of production.
Why is it necessary to have two platforms then? https://search.nixos.org/packages could just add older packages as well, right?

> For a car to be impounded it already was somewhere it shouldn't have been or the driver themselves impaired in some way. Of course they need to be able to search trunks in such a case.

It could simply have been in a car accident and its driver taken to hospital. It may even have been off the road by the time it was towed to the impound. I see this happen several times a week.
We played Nettrek on unix workstations at my college. Basically filled up the labs at night doing so on a Friday and Saturday nights back in the early '90s.

What's interesting is that different servers had different styles of games. One was more like hockey, using tractor beams to pull the puck around the playing field.

To some extent, I still miss this. The gaming was simple enough, and easy to kind of get into.
They are not employees because they can stop working at any point in the day and they decide to pick up rides or decline them instead of being assigned tasks they have to complete. Bad rating just means they get less priority not a bad performance review that gets them fired. They choose their tools (car), work location and take breaks whenever they want between rides.

And yes, Uber and Lyft are intentionally a "growth hack" companies.
It's not "big deal". It didn't cost me any money and I won't lose any sleep over it.

As I've already said, I'm curious about how/why this happened because it doesn't make sense.

I've sent an email asking about it and maybe I'll learn something if I get a response. I've never done that before so I don't know what to expect.

Scheduled rides are a neat strategy, but they're tough for consumers to use effectively. For one thing, if you're attempting to schedule a last mile ride after you get off the subway, your arrival at the pickup point could be subject to minor delays. But on the network side, a few minutes on each ride impacts efficiency in a major way.

Personally, my biggest (non ethical) issue with Uber/Lyft et al. is that they're unreliable. There are common rides you can request (e.g. leaving the urban core after work when drivers want to be heading in for bar service) that drivers simply don't want to do. I don't think there's a faster way to create negative user associations than walking an hour home in a heat wave because the pricing model failed.
Because obviously then all the MBA's, business consultants and other useless services industries don't get the real value they deserve on paper.
