The sun also emits in the visible wavelengths. Your eyes do not feel pain from bright lights due to the heat or similar. It's a response to brightness, in the visible spectrum. Without the visible component, there's no pain. With unhappy optical circumstances it could cook the retina because the pupil is dilated and there's no instinctive response to look away. Not sure how plausible those circumstances are. But I sure wouldn't put a 10 watt IR LED source right up to my eyeball.
This is not even close to true.

Most of the world really can not. It can only get up to 16, and that's with shady suppliers thanks to China ignoring international law.
Shelter is a necessity but lots of people think they’re entitled to live wherever they want at a price they can afford. They go to SF or NY and complain about rents when there is a whole country they can live in.

I don’t think communities have to allow higher density and the lower quality of life that comes with it. Desirable places are going to be expensive and that’s okay.

Personally I think if we have better rail, people can live in a wider range of places but still access jobs. You see this in Europe, and it lets smaller communities keep their way of life.

That is strongly dependent on your social circles, and is also a rather small subset of what smartphones are used for.
Landlords have 100% risk. Look what happened to California, when the state said tenants did not have to pay rent. Same for Washington, NY, IL, etc... The vast majority of people with rental properties are just regular people trying to make a living.
That just shifts the perceived inequity to:

Home ownership isn't a good financial option for everyone, but for most consumers who aren't accredited investors it's the only way to make highly leveraged trades. You can't buy an index fund with 20:1 leverage. Of course this occasionally blows up, but even then the downside is limited.

Even if ownership doesn't make sense from a financial standpoint it's still somewhat essential for parents of school age children. Renters can be forced to move on short notice if the landlord declines to renew the lease, like if they're planning to sell or redevelop the property. This instability has a cost that goes beyond financial concerns.
Even running in smaller environments:

1) You may not want your application servers having direct access to your auth service or auth database. You may not have the resources to control employee access to sensitive data when it’s shared across services. You may want to spend limited resources for security audits on the systems that contain the most sensitive data, and having them separated from everything else is helpful.

2) Depending on what 3rd party services you use it may not even be practical to have connectivity between auth and other services, and if you do, the latency may be bad enough that you wouldn’t want it to be blocking every request. This is especially compelling for hybrid environments, e.g. the 20 year old database in a colo with your user data, and a new service being built for you by consultants on a PaaS.

3) People act like revocation is such a nightmare, but you only need the auth service to sign invalidation tokens to be passed to the client-facing services, and those services only need to retain them for the max TTL of the auth tokens, after which they can be evicted. Yes, that’s something that could be motivated by having a massive environment like Google, it could also just be a way to keep costs down when you’re paying by the byte of storage or by the outbound request on some cloud. You could try to make the argument that storing invalidation data is just as bad as storing session data, but the key questions are “Where?” and “For how long?”, and then in some circumstances it breaks down very quickly.

4) You may not want sensitive user data stored in the jurisdictions where you want to host your apps. That’s not a big company problem, it’s dependent on the nature of the services you provide.
I've used 127.0.0.0/16 for real work[1]. Keeping a /16 is not much cost and helps out a few more niche cases. Although, I guess if it wasn't available, I could have used a /16 in private space that didn't overlap with my existing network.

[1] I needed a lot of localhost connections to run a TLS terminator separate from the underlying service which didn't support unix sockets. Using the 127.0.X.0 bits in addressing was very helpful for diversity in the hash used for kernel socket tables, otherwise most slots had few sockets and some slots had way too many and perf was bad. Configuring multiple loopback interfaces using more address space was a lot more tractable than changing the kernel hashing behavior, adding unix socket support to the underlying service, or adding good TLS to the underlying service. Although probably since then all three things have happened.
> You're talking about tokens in general, not just JWT.
Yes, all stateless tokens. But I have never seen an in-house token system that was not using JWT's.

Yes, query the DB or some sort of storage every time. It sounded so clean and nice and fast to just check JWTs without any network calls. But it ended up very messy and complicated. Might still be worth it in some cases, of course, but I would start my next project with random sessions stored in a db or redis or memcache or .. something :)

You can actually do crazy stuff with your sessions as well, to avoid a normal db lookup. But in practice all services I have worked on would/did not suffer noticeably for a fast DB lookup.
This thread blew up a lot, and some unfriendly commenters made many assumptions about this innocent story.

You didn't, and indeed you have a point (missing specification of expected queries), so I expand it as a response here.

Among the MANY requirements I shared with the candidate, only one was the 6TiB. Another one was that it was going to be serving as part of the backend of an internal banking knowledge base, with at maximum 100 request a day (definitely not 10k people using it).

To all the upset data infrastructure wizards here: calm down. It was a banking startup, with an experimental project, and we needed the sober thinker generalist, who can deliver solutions to real *small scale* problems, and not the one who was the winner on the buzzword bingo.

If your application can take it, drop it in the application. If your load balancers can take it, drop it on your load balancers. Otherwise you have to get your provider to drop it, if they can take it. Worse case they'll drop all traffic meant for you to protect the rest of their network.

> because of the lack of being able to pass multiple arguments to a template

I'm not sure if this I understand the issue correctly, but one can pass multiple arguments, by wrapping them e.g. into a hash (https://go.dev/play/p/89gP42K8XRb):

package main

import (
"log"
"os"
"text/template"
)

func main() {
err := template.Must(
template.New("").Parse("{{ .greeting }}, {{ .user.name }}!"),
).Execute(os.Stdout, map[string]any{
"user": map[string]any{
"name": "earthling",
},
"greeting": "hello",
})
if err != nil {
log.Fatal(err)
}
}

In my experience, the module is far from a toy, but it's not always obvious how to use it properly, at first.
Inequality is another issue. Even with enough homes, if they are all owned by minority of the population who extract rents from the rest the situation remains pretty dire.

Who knows, being devoted to each other romantically might make them less likely to knife each other in the back if the startup looks like it might take off.

Long story short, while it's not hard to imagine a problem, there are plenty of businesses owned by a couple who are romantically involved.

Could it cause problems? Perhaps. But, it's a startup. You need to be prepared to bail with little notice, regardless, for any startup (because more or less by definition they don't offer much security), so I don't think this needs to be a top concern.

> it appears the author is advertising their own prior work quite a bit

Not only that, but it's prior work that is based on a false premise. The author's proposed "solution" is based on Unruh radiation, but Unruh radiation is zero for an object in a free-fall orbit. To get nonzero Unruh radiation, you need proper acceleration, i.e., some non-gravitational force has to be acting on the object. Unless the author is claiming that Proxima Centauri has a rocket attached to it, his model fails at step one. I believe other physicists have pointed this out but the author prefers not to mention or address this criticism.
My resume is in LaTeX, so I thought about adding a single pixel that spams it with every relevant keyword so that it shows up in the PDF for the metadata screener, but I could have plausible deniability if asked about it.

This post is not very good. JWTs exist for good reasons. They may not fit your needs, and if not, don't use them. But they exist to allow Entity A to tell Entities B through Z that A had authenticated the user and authorizes them without needing to make API calls, and they serve that purpose well.
Batteries don't care about cycle count, if "cycle" in this context is every time you switch between charging and discharging. They care about how many amps go in and out, along with disliking being too close to 0% or 100%.

Limiting max charge is easier if you have extra range, and so is staying away from empty. Making the battery hold more energy only improves things. Go ahead and charge every night.

If you see someone giving "cycle count" as a spec, they mean full cycles. If you charge 10% five times, that's half a full cycle.
There are clear cut cases like with Pantheon, but for many artefacts there are no real owners left. Their cultures have been wiped out, and the people who wiped them out were wiped out too.

And frankly it's fine to care about survival of (otherwise publicly accessible) pieces of art and culture first and foremost. There's not going to be more of them.
The building does appreciate sometimes, at least here in Germany because the increasing absurdity of bureaucracy and regulations make the same class of house more and more expensive to build. At the same time, "lower classes" of houses become outright illegal to erect, leaving only the luxury segment for new buildings. Old buildings have grandfather privilege and thus become more expensive than an equivalent new build would be, simply because you aren't allowed to build new.
> Why should a landlord be unable to deduct business expenses from revenue before calculating taxable profit, when all other businesses can?

I think you nailed it. This is effectively the government saying "renting is not a business".

Think about it. The ability to "deduct expenses" is one of the characteristics of businesses. Individuals also can't deduct rent, food etc from their taxes.

Metrics are silly. Evaluate what you actually care about. Run the software and check if the features you care about when as you expect. Do a trivial implementation in the environment you want. There's no single common indicator that will replace that.

> You don't see the contradiction here? You want your phones to have location-aware features, but right afterwards say that you don't want it because it makes your device "very promiscuous".

I don't think it's a contradiction. You can have a phone that knows its own location without telling Google/Apple where it is, and that uses that information to toggle features. (I'm kind of skipping the cell carriers because you do have to give them coarse location by virtue of how cell network work.) A device can get location by purely passive GPS without involving any external services, but that's a pretty sucky experience (slow lock, low precision)... I think you can do AGPS without telling anyone where you are, though. Anyways, my point is that there is a world of difference between you having your information/location and anyone else having it.

Show HN: Skipped my 9-5 to Solve the Bookmarks Problems
TLDR;
Frustrated by the bookmarking issues, I too a break from 9-5 and build an app specifically designed for Bookmarking and Sharing https://hyperurls.com

Sometime, the links are saved in my Twitter Bookmarks, sometime it is in my Notes App, Sometimes the end up on my phone.

I always get frustrated with bookmarking stuff on social media!!

Every platform has its own way of saving links, but they all seem to fall short. You can't search through them, share collections easily, or organise them well. I was always my pain and when you're traveling and when I am travelling and come across an interesting article on my phone, it's even more frustrating because you often can't save it without logging in or using a desktop.

hence, I too a skipped my 9-5 for a couple of days and designed an app specific to streamlining bookmarks and able to share a bunch of bookmarks using just one single link and did a deep researching and here is what I found out:

The Problems which I found in Existing Bookmarking Tools:
1. They don’t focus on a single problem.
2. They are bloated and often not affordable.
3. You can’t save links without logging in.

The Bookmarking Mess:
We all save a ton of cool content on places like Instagram and Twitter, but:
1. We rarely go back to our bookmarks.
2. The systems are pretty flawed: no good search, no tagging, no simple sharing, and no real organising.

Here’s What I Did to solve the Pain Points:
I decided to create something to fix this. It’s called HyperURLs, and it’s a tool that puts all your saved links in one place. Whether it’s articles, videos, or websites that inspire you, HyperURLs helps you manage it all. Here’s how:
* Centralised Organisation: Keep all your (not just) social media links together.
* Easy Access: No more endless scrolling. Use filters and search tools to find what you need.
* Simple Sharing: Share collections of links with anyone, regardless of the platform they use.
* On the Go Sharing: Save any link from the internet using a TelegramBot, even when traveling.

Why It Helps
* Efficiency: No more jumping between apps to find your saved content.
* Better Organisation: Use tags and search features to keep things neat.
* Easy Sharing: Share your favourite finds with friends, no matter what platform they’re on.

So do you think the break which I took from my 9-5 to build the SaaS was worth it?
No-one can kick you out of your own home because they want to rent to someone they can charge more. No-one can tell you you can’t change the wallpaper in your own home, or remodel the bathroom, or get a dog.

Not everything is a purely financial decision. A home is primarily a place to live, not an investment opportunity.
Depends on the objective. In some cases, slapping together a few components is fine and straightforward. In particular if you pay attention to how other people are using them - perhaps pay attention to the provided standard schematic and layout in the spec or application note - and if you are well within the expected use for these components. Notice magazine articles. Use several sources. Something might still go wrong, but then you might also buy the wrong widget from the wrong seller...

If you are deliberately striving to push the limits one way or the other, then yeah, you will run into the exact reasons nobody else did it.

> Anecdotally, in conversations with other drivers, it seems that far too many people overestimate their driving habits.

Or conversely, folks who are making this argument underestimate the flexibility people want out of a car.

If all you factor in is the average daily work commute, then most car owners don't need a car to begin with - even in the US. There's usually some public transport, or work-provided transportation, or opportunities to carpool with a neighbor. Not glamorous, but enough to get you through your average day.

The car culture has very little to do with averages. And for what it's worth, it's the same for most other goods, from computers to kitchen appliances. I mean, how many techies need a kitchen in their home to begin with?
