Thanks for sharing that article. My understanding is that this bridge effect is actually what is happening across the entire length of the string; it's just that the boundary condition makes the effects of stiffness clearer.

Stiffness causes there to basically be a radius of curvature in the string when you apply a force. The boundary condition of a guitar string is that the displacement and first derivative of displacement of the string are zero at both ends. So, this radius of curvature will be visible there. But, even when plucking a string, rather than having a sharp peak at the plectrum, it will necessarily be similarly smoothed out. (Though, through time in a frequency-dependent way.)

In the wave equation, stiffness involves a factor with a coefficient proportional to Young's modulus. Based on the stress/strain graphs I could find, Young's modulus of a guitar string increases with tension, increasing inharmonicity. Of course, the pitch of the string also increases with tension, so there's a lot going on.

(I have to admit that the zero-first-derivative boundary condition having no additional effect is coming from my intuitions about linearity of solutions to the wave equation, but maybe it still has some interesting effect. I think the overall effect of stiffness would dominate this one, however.)

Anyone have a recommendation for label making software for the Apple ii? My ImageWriter is the only printer I own and I was wanting to run a batch of home brew labels, just like name date og/fg sort of thing.
I don't know what your point is, GP's comment already mentions a case where authority can intrude on individual rights: warrants, and there are many additional exceptions. The point of this system is not to make individuals untouchable, its to lift the authority to intrude on personal liberties out of the hands of individual beat cops and into a well-defined system and public observable record through the courts.
I question your use of "implies" there. It implies no such thing. What you suggest is one possible answer, nothing more.

> Only one side is trying to undermine the electoral process itself.

I'm no partisan Republican, but I don't think that's true. Creating seats until you gain control also undermines electoral process, and the "For the People Act" pushed DC statehood. That's a naked grab for two more safe Democratic Senate seats, especially when any concerns about the enfranchisement of DC residents could be solved with less of a partisan power-play (like letting Maryland annex most of DC).

If you read liberal-leaning comment sections (e.g. like the NYT's), there's a lot more extreme fantasizing about creating new liberal states and abolishing or politically neutering conservative ones.

I definitely think the Republicans have been "trying to undermine the electoral process itself" more blatantly, but the Democrats aren't saints either.

And frankly, if the Republican threat to democracy is so dire, probably the best thing to save it is for the Democrats to shoot their progressive wing in the head and loudly run to the center, become competitive in conservative states, and focusing on routing the Republican party above other ideological goals.
I think I'd like C++ much more if it had a proper package manager. I know there's Conan and a few others but having an official way to install a library would be so great. I recently got back into game programming as a hobby and dusted off some of my old C++ projects from 2010, and while I was able to get them up and running again (which I guess speaks for C++ as well) it was pretty painful and involved downloading and installing several packages by hand.

Using languages like Go, Python or Javascript feels much more seamless as you can just say "pip install ..." or "npm install" or "go get ./..." to install all your dependencies (there are pitfalls there as well).

Maybe our thoughts aren't reducible to material reality?
Correct, you basically invert the typical component/object oriented approach, so each property relating to some Component isn't stored in memory alongside the game object it relates to (causing the values relating to e.g. physics to be scattered around memory) but is instead stored in an array (indexed by an id - the Entity id) with all the other values for this component type, making it much more cache efficient when a System (e.g. particle system, physics system) needs to perform updates on all components of a given type (which typically happens once per run loop iteration in a game engine).

Show HN: www.instanote.io – notes in a simple chat interface
Hey HN, founder here. I announced InstaNote first on HN a few months ago that got a bunch of interest. It has grown a lot since then: I’ve made many improvements, added paid subscriptions, and the app hit 100k+ downloads on Android recently. There’s a growing list of subscribers supporting development.

This started as an app to build what I personally wanted for these reasons:

* There are many tools for complex note taking and project organization, but they don’t make it easy for quickly noting down thoughts. I wanted a fast way to write something down, and an interface like chat seemed most appropriate. Everyone is familiar with the chronology of chat messages. I’ve seen many people use chat apps to achieve these things in roundabout ways but they don’t support everything I wanted.
* Keeping track of things over time isn’t easy in other note-taking apps. InstaNote has threads and I personally use them to track my weight and pictures over time. Super easy to see trends.
* Most tools don’t have the flexibility of reminders that I wanted. InstaNote has one-time reminders + reminders repeating daily, weekly, monthly, with multiple snooze options. I have 10+ repeating reminders set for myself (this surprised me too! when it works, there are many use-cases for reminders). All reminders can be ported to a new device when you login with one click.
* Everyone tends to save a ton of links. Without link previews (like those shown in chat apps), saved links are really hard to browse and find. InstaNote shows link previews which make browsing and searching a lot easier.

Sharing notes also works great in a chat-like UI.
* CSV copy of notes: Subscribers get a CSV copy of their notes on email with one click in the app (available on Android, upcoming on iOS but emailing support@instanote.io will work in the meantime). I want users to use the product because they find it useful, not because their data is locked in.
* Basic web support is in the works.

Many app subscribers have given great feedback over the last couple of months and I am enjoying building for myself and these users. Would love to hear feedback from the community.
You did the right thing. It’s totally possible that they come back to you and say “alright, we’ll drop the non-compete.” Especially if the feds appear to be heading towards voiding them all anyway.
This does raise the question of how many cases are actually up in the air at all. One would think that given the IQ distribution of criminals a majority of cases involving arrests are quite open and shut, with suspects usually being caught either red handed or after not covering their tracks at all.

A justice system optimized for public safety will err on the side of putting aggressive, anti-social individuals behind bars rather than making absolutely sure they really did do the thing most of them were caught doing. Public safety is therefore orthogonal or even somewhat opposed to the pursuit of truth.

There seems to be a lot of ignorance in this thread about interrogation techniques. The Toronto van killer interrogation is really instructive as to how the best interrogators conduct themselves:
https://www.youtube.com/watch?v=VyHgtSy41VM

The suspect is repeatedly reminded of his right to counsel, given water, asked if he is hungry, etc. The intent here is to firmly establish that the suspect's rights have been respected - key to making sure the interrogation tapes are admissible in court.

The interrogator then proceeds to tell a series of lies about his background and interests to build rapport with the suspect - he's clearly done his research beforehand to understand which buttons he needs to push.

By the end of the two-hours-and-change video, Minassian has opened up and produced a confession so good that his defence counsel could only try to argue that he wasn't of sound mind.

Not all interrogators are this skilled - this was a very high-profile case, so the Toronto Police deployed their best - but it seems obvious that better training rather than banning useful techniques would result in more favourable outcomes.

There is still the issue of innocent people getting caught up in the system or admitting to crimes they didn't commit, but I'd suggest that there are better approaches like, once again, education of the public. You might be uncomfortable and scared for some period of time, but you do not have to talk to the police.

Yeah especially in the US, if a large corporation wants to pursue legal action against you, this can be enough to destroy your life. In lots of places, the loser of a lawsuit has to pay the legal fees of the winner, but that's not generally true in the US. That means a large law firm or legal team can file a dubious lawsuit in such a way as to tie up years of your life, and cost you a significant portion of your wealth.

Good? Why wouldn't one want a well respected and sought after expert to have this job?
I guess we have to define effective. Is it effective from the consumer point of view? That might be a long discussion, and we might assume that a world without advertising might be the most effective way to live your life, etc. But is it effective from the advertisers' point of view? Unless you want to call 5+ million marketing teams around the world total idiots, you have to assume that they are meeting or exceeding their ROAS targets and therefore pouring a lot of money into Facebook.

> It just means that Facebook is good at selling ads, whether they are effective or not.

Facebook doesn't sell ads. Marketers choose to sign up and spend money, because their jobs depend on being able to achieve ROAS targets. Contrary to popular belief, the world of marketing is very quantified and apart from experimental budgets, most of the money is spent on channels that are proven to work.

But without getting any deeper into all of this, I think I found my answer - it appears that at least a subsegment of people on HN believe that over 100BN of ad dollars (25% of overall digital ad market) is spent on Facebook in an unprofitable way, and that 5 million marketing teams get away with it, year after year. Hence, it's possible for Facebook to achieve great financial results without their ad platform being effective.
It’s not like people got together and said, “let’s have Al Gore do it!”

That movie happened, and the public is aware of it, largely due to the fact that Al Gore — whether you hate his politics or not — was in a position where he was exposed to the science, cared deeply about the issue, and dedicated himself to getting the message out. Public messaging being kind of a big part of being a politician.

> That being said, I imagine it would be very hard to be a junior employee in such an environment.

My father was a senior admin in the vendor that made the mirror, so I had summer jobs working on Hubble-adjacent projects. One summer my cubicle was next to the cubicle of a new engineer who worked on it.

They ground the mirror in one facility and then trucked it to another one, many miles away, for silvering. This new engineer was tasked with drawing up the protocol for loading it on the truck (it was driven down in the early morning on a Sunday to reduce problems with traffic).

He finishes the document draft and calls down the senior engineer for a look-over. They are discussing the part where the cranes (kind-of like fork lifts) lift the mirror. There are three cranes, and three places built into the mirror where they hook on.

"How do you know the cranes will take the load?"

"Here are the manufacturer's specifications, saying that each will take more than half the total weight. There are three cranes, so there is sufficient capacity even if one crane fails."

"How do you know the crane will take the specified weight?"

"They were vendor certified last week; I was there."

"That's not enough. The night before, you and another engineer will personally go down there and personally load the specified weight on each crane. Then you will each sign a paper. The mirror will not move without that paper, containing both your personal names."

Made a big impression on me.

Can you clarify what you mean by "millions"? The Syrian civil war is estimated to have killed just short of half a million people. The pandemic easily has a global death toll of roughly 4 million people so far. The Chalisa famine of 1783/1784 is estimated to have killed 11 million people. The Spanish flu killed at least 17 million people, though some of the more dramatizing estimates place it closer to 100 million. According to some researchers, climate change is already killing 100,000 a year[1]. So I assume you're not thinking of just seven or eight digits unless you're exceedingly optimistic.

Climate change will make parts of the world inhabitable that are currently populated by humans. It will also result in crop failures, which will cause famines. In some cases formerly native crops will no longer be supported by the changing local climate or farmland may become completely unusable. Potable water will become harder to source. Water contamination is a source of many deadly diseases.

Even if we assume most of the deaths will be concentrated in places like Africa or the Indian subcontinent, the global economy relies on these places for resources and cheap labor. People in ongoing climate catastrophes also don't tend to stay put and die in an orderly fashion, they become refugees or riot against their governments. Things can get politically messy even in the nations next door as humans tend to be uncomfortable with political chaos and mass deaths.

But unlike the Spanish flu, or the potato famine, or COVID, climate change is not a temporary blip that happens and then goes away. If all the carriers of the plague have died, nobody dies from the plague unless they get infected handling the dead. Famines can starve millions to death but once there's another harvest the survivors have food again. Climate change isn't like that. If climate change creates a drought, that's not just a drought, that's now dry season and it will be dry season every year from now.

There are currently 7.8 billion humans. There's absolutely no reason to believe climate change can't kill billions, especially once it's managed to kill the first hundreds of millions.

Keep in mind that it's not about "addressing" climate change. It's not a moldy bathroom tile that you need to clean up or replace before the mold spreads everywhere. It's a fire our entire way of life is fueling every single day. We know what needs to be done to slow it down to survivable levels (or at least levels that are lethal for less than 1% of us) but we can't just pass legislation or appeal to personal responsibility to do that because it involves changes that would be economical suicide for anyone doing it alone. The world economy is playing a game of chicken with each other and nobody is bluffing.

Certainly; I don't think anyone is claiming they're universal. Just that enough players do it that it's a concern; you can't easily name and shame the companies that do have them, as an employee, because most companies do. And that they're net negatives, and shouldn't be legal (at least, not in the form many are in).

Ask HN: How should I validate my tech-hiring MVP?
I've been holding on to an MVP that I created earlier this year but never even started marketing. The project is completely unvalidated, so that's one mistake. It's hard to tell if this is something anyone actually wants.

It's https://www.sookiestack.com/ - basically a way of automating the process of assigning and keeping track of take-home coding and design challenges (automatically creates a github repo for each candidate). Ideally it will cut down on the amount of time spent on this process.

I've considered doing a lot of cold emailing to see if I can get anyone to try it, but it would be better to get someone in my network to test it out and give feedback - see if it's useful for them. The problem is, my network kind of sucks.

Does anyone around here have any ideas of how I can get some beta users and start to validate the concept? Even better - if anyone is interested in beta testing (for free of course), it would help a lot.
