Yeah, it's not like anyone needs that functionality to do work or anything. In fact, why not just refuse to boot the computer in the first place? That'll stop a lot of security problems.
What part of it does it forbid? You could relicense the existing SW stack, no?
Why in the holy hell is this getting downvoted[0]? Advice on what kind of ammunition to use during the endless war on bugs that we humans have perpetrated for our own comfort[1] is without a doubt invaluable information.

[0] This is not snark.

[1] Snark aside, I for real do not want roaches etc. in my house, and appreciate non-poisonous methods of dealing... while at the same time struggling with the fact that the insect population in my state, which is KNOWN for bugs, has visibly plummeted within my lifetime.

Hate to be a spoilsport but I wonder what their safety record is like. The shots where the camera was pointed up the barrel made me cringe. "Treat like a loaded weapon at all times" indeed! Of all things to get in your eye high-velocity salt seems like it would be pretty bad.
It is not a non-sequitor, it follows from the concepts, something being worth doing is not a part of physics/math. If math/physics is all you have then you have no "worth doing".
There's a youtube channel of these videos: https://www.youtube.com/channel/UCnERyC7dwJwTvEyzYz6uxHw

For those not deeply familiar with U.S. structural issues regarding race, a random viewing of the video will show the unfortunately, the victim/rescued person is likely to be African-American. The reasons for this are complex and sad.

Anecdotally, as a child, my family wasn't well off (and at least once homeless), and for a while lived in a lower class urban neighborhood that just happened to have a nice public pool. However, I know that my swimming education started as a toddler with my mother taking me to the local recreation center for early swim classes. Later when I was maybe 6 or 7 my older brother, a champion high school swimmer, further reinforced this until I was very comfortable in the water and had no problems even at the bottom of the deepest parts of the pool. All through my early, middle and high school years I had countless opportunities to swim, and to learn new skills around water. When I was 17 I could easily complete a mile-long endurance swim, or pull a bucket of rocks 20 feet up off the bottom of a pitch black lake.

My African-American friends, starting way back at that housing complex, had no such similar experience. I remember long summer days with my friends teaching our black friends to swim so we could have more fun in the pool as a group. As children, it wasn't entirely unusual that one of us kids couldn't swim, as maybe their parents just hadn't gotten around to teaching them, so we took it upon ourselves -- never really noticing the pattern that only our black friends hadn't learned to swim yet. What we didn't understand is that most of their parents would never teach them, as many of them in fact couldn't swim either or discouraged it for various reasons -- creating a generational problem.

Now, older, I've come to see and understand the sadness of the situation and hope it continues to be addressed in a more systematic way.

Please, if you can't swim, learn to. Teach your children or have your children taught. Water sports are tons of fun, but your safety is mostly on your ability to swim.

Volla doesn't help much in the OS market - it's just another Android phone with unlocked bootloader, relying on Android driver infastructure.

If you're interested in alternative software better invest in Librem 5, or if it's too expensive for you get a PinePhone and start hacking.
There is a small car rental company in my town that does just this although it's more like an hour rather than 15 minutes. They've got all of my details on file so it's as easy as a 10 second phone call because the person recognises me by voice.

Both are feedback but IIPs (Imaginary Internet Point) are more aligned in incentives even if they usually give less utility to the recipient. This may be a feature and not a bug as the utility can be used to distort incentives to their own favor.

IIPs aren't perfect by any means of course.

If you have any opinions on GraphQL vs Cypher, I’d really appreciate it!

Flying or on treads?
A healthy respect for pools is an excellent idea. There are few activities a child might reasonably engage in where it could go so wrong it might end up in their death. Swimming is one.
Thanks - that makes total sense for a company that does this for a living, especially on GL for more scalable rendering. I'll also be checking out your product.

As far as I'm aware, the NHS provides free healthcare to people visiting the UK.

As regards providing free healthcare to anyone regardless of country, that seems next to impossible without providing the infrastructure necessary within the country they live, which would indeed be very difficult to work out. It seems like a good goal to work towards - everyone regardless of nation having access to reasonable quality healthcare.
I was a lifeguard at Disney World (Disney lifeguards work the waterparks, all the resort pools, and the pool and the lake at the private cast member park, Mickey's Retreat) in the late 90s. I believe at the time it was 20 minutes on duty, 5-10 minutes rotating to the next station. There would always be a couple lifeguards rotating in this scheme and they'd able to assist if necessary.

It was very boring, and keeping my mental acuity sharp towards the end of shifts was a problem. Take care swimming late in the day.

Also, I don't ever swim in public pools anyone. We had to shut down the cast member pool one 4th of July because it was so dirty and so soiled, we couldn't see to the bottom of the deep end (6 feet / ~2m) and it presented a drowning hazard. The pool was closed for like 3 days after that while we waited for the water turbidity to go down.
Well, there are several kinds of allocation strategies, so while the general malloc does a best-effort, I have no real choice with exceptions at the moment, other than to turn them off.

I do a lot of stuff in embedded, and it would be nice to have something like this. I'm also experimenting with using C++ as a compiled scripting language for a game engine, and for that I would like the binaries to be really small.

Because of docker, compiling freestanding binaries for any architecture is not such a barrier anymore.
Isn't spraying salt over your organic farm counter-productive?
I think they're referencing YC specifically. While money is money, there is a prestige put upon the acceptance into YC (obviously more so in this community). This, I believe, is what's being discussed. Not the validation of business ideas via VC investment.
As an engineer, I've spent so much time writing documentation on different platforms. It's always been the task I dread the most. So I built out Digital Brain: it helps auto-generate the basic documentation in Python and then gives you a fast and beautiful interface to finish up the rest of it.

Would love feedback and what you think!
Async/Await on Embedded Rust
> Way simpler to do on Linux than M$ Windows.

Completely unnecessary on Windows since it is an operating system, not a kludge of random source code from the internet.

> I mean, flatpak, appimage, docker, etc ...

Which of those is ubiquitous enough to ensure availability of what you're looking for in that format? In my experience: none of them. AppImage is easily the best, but the community seems to hate it because it makes things too flexible and simple or something.
Computational Connectomics: An Interview with Casimir Wierzynski
Well, in the case of C++, since the standard library uses exceptions everywhere not using them is a pretty big "cut". Basically either you don't use the standard library or you write all your code in a completely different paradigm.

For example, since constructors can't return error values reasonably, you would have to make them all private and use static factory functions, or similar workarounds. It's certainly possible, but much less pleasant to work with.
Not in the US at least.
High-Performing Team's Checklist
This again? The solution is almost never legislation.

If just 20% of prospective buyers devoted 1/2 their budgets to a common open solution, they could break out. If there were a tiny company offering an old school model with modern features at a competitive price, that would be enough. Then, if farmers choose to lock themselves in, it would be a real choice and their own fault.

BSD didn't need legislation. GNU didn't. Windows still thrives, but people have a choice. Just convince ADM and a few others to throw some pennies at a startup. Except that the new licensing greatly benefits those giants. So you'd have to convince 100s of little guys to throw big money your way.

Some issues i think reddit has is that they haven't been great about helping their helpers. I remember toolbox being the only way to moderate properly. It not actually being a tool by reddit itself and a massive resource hog and hampered by the size of the wiki for big subs.

Also reddit not curating the moderatorship of it's big subs unless there's controversy. Making it so the top mod can basically take over, disappear, etc.
Basically the tiered nature of mods is an issue imo.
I noticed that too. The last try was the kid try to grab the ring in a hurry, but the ring is too big to grab he actually pushed it away. Seem to be really dangerous.
The first UI config example has a PING tile, but PING type seems to be disabled by default, and I can't find how to enable it in the docs. So maybe a good thing to make more clear for people wanting to test quickly.
I fully support Right to Repair movements. John Deere/Apple et. al doing this is pure unchecked corporate avarice.

With that said, I have a hard time feeling sympathetic for midwestern farmers. They most likely vote straight Republican every election, and I'm pretty sure fixing this problem is something their Congress reps don't care about too much.
Would this work for mosquitos in the house? I can’t figure out a good way to kill them.
I'd argue that Quora by itself is nothing more than a search engine optimization scam.

I'd also have argued the same about Medium half a decade ago. It still is, in my opinion, but the people putting content on it have significantly improved.
This seems like the "oh you're busy, you just haven't learned how to manage your time effectively" feedback that's not helpful. Someone relatively smart probably has a decent idea of the constraint set in front of them. Let's say the company is close to failing and by working your absolute hardest you can keep it alive for 9 months. Would you not do it?

Like maybe there's some insight on time management but after rudimentary time management...it's probably something else.

60 GHz is unlicensed in the US. Bridgewave and others have been shipping 60 GHz band point to point outdoor radios since 2008.

71-86 GHz ("E band") is light licensed, which is easier and less costly to coordinate than the traditional 6/11/18/23 GHz FCC part 101 microwave bands.

Ask HN: Anyone Connected with Vueschool.io? SaaS Billing Best Practices?
Is connected with VueSchool.io I can't get any further reply from their support and would appreciate getting connected with someone there.

I signed up for their black friday promo. I've been too busy to use their tutorials. I noticed another charge from them this weekend, I emailed them the same day and let them know I'm not going to be able to use their service this month, please refund today's charge and I'll sign back up in the future when I have time.

They replied with this.(names redacted)

Hello,

I am sorry to hear this happened to you. You have signed up for a subscription with automatic renewals. As stated in the Terms & Conditions we will automatically charge all active subscriptions when they are due.

I am sorry, but I cannot provide you with a refund on the latest charge. We are not providing refunds for the subscriptions that you forgot to cancel or due to lack of usage.

If you wish to avoid your subscription's automatic renewal, be sure to cancel your subscription. This allows you to continue using your subscription until the expiration date but prevents your subscription from auto-renewing.

Have a nice day!

All the best,

vueschool.io

I thought this was a SaaS best practice, if a subscriber receives a charge, aren't using your service and they requests a refund the same day, you give them a refund and keep a customer happy to return later and recommend your service to others.

Now they just aren't responding to my support emails.

I've tried sending DMs to the two instructors on Twitter.

I just want to get connected with someone there.

Let me know your thoughts on this.
Maybe, or maybe you lack logic + specific situational insight. Perhaps you spoke too soon, before understanding.

I am an experienced and creative full-stack software engineer that is looking to join a mission driven company with interesting technical challenges. I have built complex web apps, designed algorithms, built a deep neural network using TensorFlow and can pick up new languages and frameworks in a short period of time.
Would be interesting to try with diatomaceous earth.
I'm having trouble seeing what it is about this scenario that would make it look so different from a star with planets (which is still very hard for us to detect) or surrounded by clouds of smaller debris.

Is the idea that the habitats would be much larger than planets or that there would be far more of them for a given total volume of matter ?
Why would separate spheres be any better than counties. One of the things that shot us up is the industrial revolution and that was mostly powered by cheap trade routes by land and ship.

As in trade is very essential for growth. Both of goods and ideas.
Small special wikis are very different fron Wikipedia.
There's no doubt it's in our DNA. Forming groups with likeminded people is what kept our species alive for hundreds of thousands of years. And it's only been in the past ~150 years that we as a civilization have started to seriously care about the wellbeing of others unlike themselves. We've undoubtedly come a far way, but that's not to say we don't have much further to go. Fighting with our innate tribalistic tendencies is hard.
Personal opinion, based off my own experience and teaching other children how to swim:

Flotation devices have no part to play in teaching how to swim. Parents (or teachers) holding their children and teaching them how to float is step 1. Only after the child can handle themselves in water (float, know when to breathe) should they be playing with flotation devices.
Starlink is probably Rural's best bet.
How come no one has commented on the fact that most of these videos include someone falling off an inflatable ring in the "deep end" of the pool while having virtually no swimming skills. It seems like a no-brainer to me that it's a bad idea to float out on a ring if you can't swim. Is that really common?
Ish in the UK, see http://static.ofcom.org.uk/static/spectrum/fat.html

Some ranges are usable for Industrial/Scientific/Medical (ISM), and there are exempt low power devices although I leave it as an exercise to the reader to find out which:

https://www.ofcom.org.uk/__data/assets/pdf_file/0028/84970/i...

For example:

IR2030/7/2, wideband transmission systems that are not fixed can be used up to 40dBm between 57-71GHz. Fixed systems are allowed, but not within 6km of certain sites. You can also use it for tank probing radar under various situations. One of them is MOD Hebrides which is a large closed area for weapon system testing, another is Castlemartin training area, and another near Luffenham (no idea about that one). Presumably it interferes with military radios and at least two of those sites are used with live ammunition, so probably it's a safety thing.
>Rejection by YC means nothing at all.

More accurately it probably means "Honestly, we probably didn't even look at your idea very well because we have a shot glass to fill and 10 fire hoses of output trying to fill it. Likely, for some entirely arbitrary reason, you did not make the cut. You may or may not have a good idea but we lack the time to tell you"
No, it would not allow you to create consciousness, it would simply mean that there is no such thing as consciousness. eliminative materialism would be true. there would be no 'you' to live forever.

Us not knowing exactly how something works has never stopped us before from looking into it.

With "a simulation of digestion" I specifically mean a software simulation, not a hardware simulation. I assure you I had a meaning with the text I wrote, it is not meaningless. The meaning is for me to say, your interpretation of it (and this is the point) underdetermines the meaning of it. You fully determine what i meant simply from the characters on the screen. Physical instantiations of abstract items work the same way. An item needing to do something is irrelevant of it being able to, a software simulation of food does not actually digest food. A software simulation of abstract concepts do not actually instantiate them.

I am repeating myself again but any AI system you believe to have instantiated the abstract concept of triangularity is just an interpretation on your part to having done so, you might as well interpret it to simply being a room heating device or the implementation of some other algorithm that also matches the behaviour.
General capacitor question

If you take a charged parallel plate capacitor and pull the plates farther apart does the energy in the system go up or down?

The equations seem to be geared to how distance affects how much you can charge a capacitor. But if it’s already holding a given charge, I don’t think the basic equation applies.
Except, they're sending all the content to me, I show only a subset of it (that is, the content that they sent me, instead of the nag-box they intended to go on top of it).

I actually thought of making a plugin to do this, but decided against it, since I'd rather just keep reading my free articles than making it so easy for everyone to do that they'd be forced to remove that feature, which is a likely consequence of this repository.
> The data surrounding the biology, epidemiology and clinical characteristics of the SARS-CoV-2 virus [the virus causing the current outbreak] have been growing daily, with more than 400 articles listed in PubMed.

After reading dozens of media articles about this virus I still didn't find out what kills it reliably, except, maybe, alcohol.
What about temperatures? What type of alcohol? Other disinfectants like chlorine? The media seems to be void of these details and mostly fuels worry and panic.
The First Step to Taking Control of Your Habits
Sometimes they’re even too busy to even get gas, which very quickly ends poorly.
If you just want to have a nice visualization to look at some numbers, fine. But, if you want to detect problems, it's ineffective. I saw too many companies do it to actually monitor the state of things and find out problems with charts, numbers, traffic lights etc.
