Ask HN: Why is it so hard for devices to determine WiFi network health?
I routinely run into the below scenarios:

- As I’m leaving a zone with WiFi, the signal drops to 1 WiFi bar for way too much time and tries to remain on the network even though it no longer serves. Forces me to toggle WiFi off so my phone switches to celular data

- It connects to a public WiFi I’ve used before, has full WiFi signal strength, but in reality there’s no service because to actually use the network I have to login, accept terms, or something along those lines. And if I don’t do that I’m unknowingly without service because my phone can’t tell this network isn’t actually working

- Similar to point 1, my phone will pick up a WiFi network that’s far away (eg my home network while I’m at my neighbor’s house) and grasp to that weak unusable 1 bar of WiFi signal forcing me to toggle WiFi off (or just forget the network if it’s one I don’t commonly use)

So, I’m wondering if there are any networking folks out there who can explain why this is a hard problem to solve.

Ideally there’d be a piece of software that can determine “should I use this WiFi network or cellular data?”. Pinging a health check or something similar perhaps?
For developing .Net (Core) on Linux? Rider is your best option from JetBrains. Most development still happens on Windows though because Visual Studio is best option if running Linux Desktop is most important thing for you.

However running it? .Net runs on both Windows and Linux with performance generally being much better on Linux. .Net Team IME also recommends Linux as well unless you are doing some Windows only things.

Web Server? .Net comes with built in cross platform Web Server called Kestrel which is pretty darn performant so most people just run Kestrel and proxy it with something like Nginx/Caddy though it's not required.

After dealing with both companies, if you put a gun to my head and said "Oracle or Microsoft?" Microsoft hands down. Both are licensing nightmares but Microsoft has never come close to hostage taking behavior that Oracle has. Don't even get me started on Oracle Database Core license requirements in virtual environments. MSSQL never went that bad.
I have read that paper too, but you were referencing the ~25% from your friend in industry, which corresponds to the editorial I cited, not these far more rigorous studies.

There's no reason to be insulting, especially when linking to well known studies.
It's not defeatist. The point is that legislative decisions still matter, a lot.

Take the Chinese Great Firewall, for example. Yes, you can use technical means to circumvent it, but the effort required (and inevitably degraded performance) means that the median citizen does not.
That doesn't sound right at all. I mostly use mine as a TDR (50 GHz with 83651B) but I can generally reload saved calibrations from months ago, less than 5 minutes after a cold start, and still see < 50 dB return loss through 20 GHz if I look at the same load.

I'd go through the receiver channel tests in the manual and try to isolate the problem to the test set or IF box. Does S21 drift as well?
Do some masking of curse words with sht, ?!, verybad, or similar? Something that Claude will accept. It might work, if users are just generally badmouthed, not actively trying to trigger the model/system.

Healthcare systems costs and operations are a mess. Here are a few examples, hospital systems setup places that can do anything which adds complexity and increases costs. So, they are not cost optimized. The more a facility can do the more it costs to do any one thing.

Hospitals loose money on many procedures while making some money back on others.

There is also costs around staffing. For example, nursing schools aren't producing the growing number of nurses needed. Supply and demand kicks in.
According to Glassdoor, the average salary for a Catholic priest in the United States in 2024 is $104,699 per year, with an estimated total pay of $206,187 per year. This includes an estimated additional pay of $101,488 per year, which could include cash bonuses, tips, commission, and profit sharing.

> physicsts don't want to give up the beautiful and geometric simplicity of 1/r^2

Eh, just like MOND proponents don't want to give up the beautiful simplicity of "If something is attracting me gravitationally I'd better see it!"

When you think about it, there's no a priori reason why a particle with mass should interact with any other force. We'd just like to assume it because it seems "simpler" that way.
There are fewer branches but there is now a data dependency between loop iterations which makes each iteration slightly slower (maybe 1-2 cycles additional latency per iteration).

Because newlines are relatively common and unpredictable a state machine is likely better. But on a long file with no new lines and no spaces the branching one should be slightly faster. (All reasoning from first principles; I have not done any benchmarking!)

It's pictures like this that seem to make Dark Matter not all that mysterious. It's clear that the galaxy is surrounded by a lot of dust, and you can clearly see that even as you extend outward and the light drops off, there is still a lot of dust that is just not illuminated.
I don't think that is the case. AWS is a very significant investor and if you meet with their business development team they will recommend deploying on bedrock (which is Nvidia). There are also press releases like this[1] stating they use Nvidia.

This is speculation because I don’t think any of the key players ever explicitly stated this is their strategy, but this year it feels like there’s some significant foot dragging on things like Sora and GPT-5. The big AI players really don’t want AI to become an election year punching bag and don’t want any major campaign promises around AI to placate a spooked electorate. And they really don’t want it to be revealed that generative AI powered bot armies outnumber real human political discourse 10-1. And they absolutely do not want an AI generated hoax video to have a measurable effect on the polls.

It’s a stopgap. If we get through this election without a major public freak out, it gives the industry 4 more years to take LLMs out to the point of diminishing returns and figure out safety before we get knee jerk regulation.
I am aware of its usage, but switched to installing things into separate folders in /opt many years ago. That way, it’s easy to uninstall stuff (rm the right subfolder), and you can install apps that don’t follow the Unix conventions into the same place (e.g. Matlab).

You’re right though, I haven’t seen any mainstream distributions (i.e. no GoboLinux) that removes /usr/local.
>IMO, both Boeing and NASA are under quite a lot of pressure to not require further tests from Boeing because there are just enough Atlas Vs (the rocket that Starliner launches on) for Boeing to complete it's contractual obligations.

>Any further tests would deplete that stock.

I hear what you are saying and it likely affects their decision, but lack of hardware in the future should not be a consideration in this decision at all. If there is any concern, safety of the crew should be priority one.

IIRC, Aerojet is the sub on this system. Surely they understand propulsion well and it is unfortunate that Boeing's name is taking the hit.

Scale, I imagine. Orchards are big. How many robot waterers would you need when you have to spend time at each individual tree (or groups of trees) to water it/them? How far is it to the nearest refill?

Put another way, drip is massively parallel. Robot waterers, not so much.

Congrats on such a neat idea so nicely executed ...
A price conscious consumer will not purchase this then.

I am confused at what the issue here is then.

The business presumably set their price for their target audience. If that price is too high then you are not the target audience.
Does the commercial tasking feed into the open dataset? Or is it more a case of once the satellite is up, might as well keep it busy?

Just wondering since the distribution of locations shown in the blog post seems particular.
Right now it’s $2500/year unless you have more than 100 servers, each server thereafter would be $25 on top of $2500.

It’s most likely because the costs of doing any business with other businesses isn’t worth it with a $25 minimum.

I hope they get some feedback and reduce the minimum, but I completely understand the rationale.
Hypes come and go. They rarely correlate to the real world usage. Spring, VueJS and Angular are huge, much bigger than HTMX will ever be, but nobody is raving about them.

Svelte is still growing. Nothing has happened. React ecosystem is so full of commerce that there're always many voice talking about React. I often think that people praising HTMX are comparing it to React, which is by far the worst of all SPA frameworks.

SvelteKit on the other hand is such a succinct yet powerfull all-in-one framework that HTMX (with the required backend with routing and template) appears clunky compared against it. But as I said, most people coming from React and I fully understand why HTMX appears as such a relief. Because it is in those cases.
plastic packing peanuts vs paper stuffing, paper/plastic bags, blister packs vs cardboard boxes, paper-backed tape, paper/plastic plates, straws, etc
If at some future time, we actually find a way to recover plastic / oils / utility from plastic that's sitting in a landfill, someone will then go back and dig up landfills to find it. If every trash bag has 10-15% plastic in it, because we don't bother to sort our stuff now, that's much less efficient than finding the part of the landfill that is 80% plastic.
Very cool that they were developing the one-gyro control mode all the way back in 2004, and had in-flight tested it by 2008. Seems like they were well prepared for this eventuality.

The reversed-biased method is actually the basis of single-photon detectors used in quantum optics experiments, especially experiments with entangled photons. Here's a paper that uses exactly this--reversed-biased red LEDs-- to introduce physics undergrads to the essential concepts:

Sometimes its the LEAST expected thing (that one this article does not cover).

Some time ago I had some really cheap SATA 2.5 SSD 256 GB in my laptop.

If generally worked well - system (FreeBSD) was responsive but ... when I deleted large file (like 1GB+ size) then the system almost FROZE ... until file is deleted.

After some investigation with Allan Jude (thanks again) we came to the conclusion that a single TRIM operation (for delete) take about 500ms (half a second) ...

By default ZFS on FreeBSD uses up to 64 TRIM operations PER SECOND (the vfs.zfs.vdev.trim_max_active setting) - so the SSD was literally DoS with TRIM operation and it crippled it to its knees.

After switching this option from 64 to 1 it solved all the problems and everything was smooth and fast again.

Details below.

% grep -A 1 -i trim /etc/sysctl.conf
# ZFS DELETE FUCKUP TRIM
# vfs.zfs.vdev.trim_max_active: 64 -> 1
vfs.zfs.vdev.trim_max_active=1

Hope that will help someone.

> In a dense city most people don't even have a car.

Yes, but the city need a far more expensive metro network, surface buses and so on, witch in term of raw materials demand much more than cars and in term of energy demand the same or even more because metros have also stations and even with metros and buses we still need cars and van for a variety of activities, vehicles used for work (like a small Transit for a plumber or an electrician) but also usable for private stuff. The TCO is still not in favor of such model, despite many (from the interested ruling class) claim the inverse...

> I live in an apartment building from the 50's. With just 2 walls of our building retrofitted with insulation I now barely need any heating in winter, try that with a single family home.

This means that you live in a nice climate, where summers are not too hot and winters are mild. Such areas exists and are typically densely populated also because of the climate but they are a very little part of the inhabited earth, or you are in a less nice climate but being "in the middle" you get "free heat" from some apartments underneath and "insulation" from apartments over yours. Again that's true for some, but in TCO terms it's still not favorable for the humanity at a whole, only for some humans.

If you are in mild climate a single family home would barely need heat as well, not if you get free heat from neighbors of course BUT a new single family home in the same climate can thanks to insulation and mere design (compact form, large windows on the southern side, roof/other element shielding the Sun in summer while allowing it pass in the winter etc) and while you might profit from your neighbors they still have to heat/cool anyway, it's good for you but it does not reduce the overall consumption.

Just for a personal counter argument: I was living in an apartment from the '60s in a mild climate, it's heated with 24kW methane. I live now in a home twice the size/a bit more than twice the heated volume, in a much colder place and I heat with 1KW most of the time, climbing to 3-4kW few late night and early morning between January and February, the maximum absorption recorded for heating was at the end of January 2017 a single night with a minima of -24.8℃ (-12.64℉) with 6.3kW. In raw material terms electricity here means nuclear (I have p.v. with small storage, but not to heat the home at night) and the grid, gas means a much more raw material and energy hungry distribution network. So again building new home demand energy, but in their useful life we amortize it and we evolve. Remain in old buildings demand still more, many times more in many cases, just to keep them operational and we do not evolve. Can we change them now? A 40 apartment building build today respect of one 40 apartments from the '50s cost at least twice... You need to relocate 40 families for an year instead of putting a small container-home in the garden for two-thee month...

> Wouldn't you like to know the absolute crap that comes through those forms

Usually it's because too much is hidden.

Not a SAS, but I once tapped an ad for redoing my shower. No prices, no way to know even approximately what it should cost.

I wanted more information, but I didn't want a phone call. I filled out the form asking for some high-level information on pricing, and that I didn't want a phone call.

Needless to say, the rep never responded to my inquiry.

But, put yourself in my situation: I don't want calls at random times of the day that are convenient to a salesman. I want to talk on the phone at a time that's convenient to ME, and only if I know the (ballpark) range of what you're selling costs. If a new shower costs $5k, and I won't be in a position to spend that for 18 months, I want to know that I should pick up the phone then, not now.
South Florida. Definitely not coral rock.
Yeah, that's exactly the kind of stuff very few people are going to see. Even this HN post here is seen by relatively few people.

Also, about 90% of the people respond will fall through. I'm sure people say "yes" with the best of intentions, but saying "yes" in a wave of enthusiasm is easy, and then spending a lot of hours on it ... not so much.

My favourite example is someone who said "yes, I'll help maintain", was added to the GitHub repo, made a new issue with a long plan on how to deal with the many open issues, and ... was never seen again. Never actually dealt with any of the open issues. I'm sure this was done with the best of intentions (and their profile said they're a student, so I don't want to judge harshly), but this was a rather marked example that made me laugh.
Given that life exists, and life requiring improbable actualities, those actualities existing are not evidence. We are very lucky, we live in a geological era at a specific location of the universe that has hit the jackpot of actualities to allow life to be sustained.

I might be mildly autistic, I'm not sure how to say this more cheerfully.. but no - the fact water behaves slightly differently is not evidence for intelligent design. What's more, there can never be evidence for intelligent design because it is a non-falsifiable assertion. It is faith.

This just feels familiar to the intelligent design vs evolution debate. The idea being that if 'evolution' can be shown to be false, then intelligent design is true. First, intelligent design is not science, it is faith - it cannot be shown to be false and therefore a prime requirement of a scientific hypothesis fails. Further, if evolution is false in the end, then it does not mean intelligent design is correct, it just means we have no clue - we only are left with more questions and fewer answers.

At a prior employer usually a team lead (without purchasing authority) would be told to go get a quote, go through all the BS, and only then hand over to “the higher authority” who can actually make the decision.

I think the self can be disrupted by significant alterations in memory storage among other things. I think memory is one of many key ingredients in having a self. When your memory is adequately disrupted your self is disrupted. Without a self subjective experience is radically different than with a self. It's radically different in that it's often described by the self (who stops being blackout drunk at some point) as being a discontinuity similar to sleep. The interesting thing here is that people who are blackout drunk continue to do things that a clinically-conscious person does (eat, talk, stumble around). Your experience is really interesting too - you seemed to still have an intact self, just not extended memory beyond 30 seconds. I think maybe we are talking about different things or my view is wrong.
