Nitpick: currently in the US, most public libraries do not regulate anyone, of any age, from reading “adult” books.


I didn't say public libraries, I was going to say bookstore but picked "library" because I wanted to drive home the point that even a kid whose parents didn't give them any money would be allowed to access the materials. My point: if someone opened a facility to knowingly give kids books about sex acts (and not the "sex ed" kind), we would all agree they are a creep.


They wont allow minors to take out porn. Simply, they wont and it would be illegal for them.


Calvin and Hobbs, the comic strip, has been banned in Tennessee schools on the grounds that it had pornography in the form of Calvin's naked butt being in some cells.

What is adult content? A cartoon butt? A book on breastfeeding? "I can't define porn, but I know it when I see it" has led to Calvin and Hobbs being banned.


I think the point they were making is that a child can walk into a library, pick up any book, and open it. All without any adults being in the loop. They can do that today.


Yeah, and my point is that the "pick up any book" thing is hiding the fact that selection is in fact seriously limited.

And second, underaged kids can not checkout non kid material without adult in the loop. That part is simply not true, the librarian will say no to the child or ask for parents permission.


> hiding the fact that selection is in fact seriously limited

If your goal is "prevent children from accessing adult material", it really isn't that limited.

> underaged kids can not checkout non kid material without adult in the loop

They don't need to. They can read it in the library; that's what libraries are for.


Have you ever been in the library? Cause they really limit minors.

And obviously "adult material" is not referencing cookbooks for housewifes nor antic philosophy nor fantasy books meant for adults.

It does in fact means porn and such.


I have been to my library yes. You don't need ID or a library card (unless you want to check something out or use a computer) and you can pick up any book you like (including e.g. 50 Shades of Grey), sit down at a table, and read it. There are children in there all the time and there isn't an adults-only section.


A minor can walk into any library I've been to, grab any book off the shelf, and read it.


You can read a book without taking it out.


Meaning anyone taller than 4’ can reach tedious essays about porn.


What public libraries have porn?

Or is it the pearl clutching where a novel with a same-sex kiss is smut? What about all of the graphic acts that happen in the Bible?


10 year old me definitely checked out the Clan of the Cavebear books and similar from my local library, no one cared.


My idea of a hot date was looking up dirty words in the unabridged dictionary.


Pretty much none which is exactly why the comparison to libraries makes zero sense.

And yes, there was considerable pearl clutching over same sex kiss. To the point the supposed old school bastions of freedom would not print it, would not put it in the library and would do everything possible for kid not to read it.

The physical world of back then was considerably more restrictive in terms of what kids could access. Whether in the libraries or outside of them.


I mean you can be a local bar that hosts KKK rallies and sure that’s a legal thing to do (in USA), but you will still end up being known for that, probably by many names that don’t just include “phobia”. And of course, the impact of bringing together a KKK rally inherently impacts your local community since you may begin to see things like lynchings in the news or in person.


Are you arguing that communities should be allowed to moderate behaviors that that community finds objectionable?


TBH TI-89 titanium is a better engineering calculator since the UI is way better. I have both a HP50G and a TI-89 titanium and I've done way more useful engineering work on the TI-89 titanium just because it's so much easier and accessible. Also of course, BASIC is a lot easier than reverse polish lisp for making some quick scripts.

Also I will add, there are known symbolic math issues on the HP50G due to the CAS system it uses. I will see if I can find a link.


I've used both extensively. I disagree with this. I dislike the HP48 series but I dislike the TI89 more. It's probably because most people don't understand how to use the 50G properly. You really need to go through the HP training video ( https://www.youtube.com/watch?v=OTPruRVV-e8 ). Incidentally if you haven't watched that it's worth watching on its own - great production! In an engineering context, the 48-series was designed to produce small composable reusable programs and tools in the file tree which can be executed quickly.

Try a quick EE example for parallel resistor calculation that takes 2 and puts 1 value back on stack

<< 1/X SWAP 1/X + 1/X >>

Store that in RPAR in whatever directory you want or HOME. Then you whack in 2 resistors and hit the RPAR F-key. There is nothing faster or more efficient than that.

I still use a 15C all the time though. Even easier! 99% of what I do is on paper though and ends up getting chucked in the numeric solver.


For something that requires writing BASIC (or RPL for that matter), I think I'd rather use a programming language on a PC

However, keystroke programming a calculator, where you can still somewhat do simple loops with goto-like constructs when needed, strikes the right balance for the limited UI of a calculator

So something like the HP 15C is nice.


Got both as well (TI-89v2 and hp50g).

TI-89 preferred by far. hp50g UX is bad, particularly the latency makes me sick.


Somehow the TI-89 had _both_ snappiness and relatively advanced 2D math display.

The TI Nspire CAS is the pinnacle of calculator UX, though - crisp , large, and hi-density LCD, beautiful math formatting, and dedicated alpha keys. I’d rather be doing symbolic stuff with that. In college physics it saved my ass by doing unit analysis on my answers as a double-check, converting units to base SI units and then doing as much simplification as possible.


So scratching definitely still happens, both on sapphire camera lenses and new scratch-resistant screen technology. I’ve mainly had it happen with concrete. I think concrete sometimes just has some rocks in it that have a very high hardness because I’ve gotten pretty thick scratches in new iPhones when they’ve taken a slide over a rough concrete sidewalk due to a drop while walking.


I've similarly experienced bad scratches whenever my phone and my keys come into contact, hardened steel may still be able to cause scratches?


Your keys are by no means hardened steel. If they are steel at all (most are brass or silver/zinc), they would be mild steel. If they were hardened they would be really difficult to cut. The harder you make a steel the more brittle it gets. Think about what happens when you slam a file with a hammer vs a large nail.


Considering how easy it is to break keys in the lock, I'd say they're definitely more brittle than malleable?


I think that's mostly from mild work-hardening, I haven't experienced that with a brand new key.


What kind of material are your keys and locks made from? Over here nickelsilver or nickel plated hardened steel is common for keys and a combination of brass, steel and titanium for locks.


This should not be possible with any type of modern phone screen. Do you perhaps have a plastic screen cover that is scratched? Or key metal could be deposited on the screen and just need to be scraped off


Depending on your location and lifestyle, your keys and other possessions can easily collect a dusting of tiny sand particles. Quartz in the sand can scratch most types of glass.


No, it's possible on modern phone screens. My Pixel 8 Pro has Victus 2 (AFAIK), which scratched very easily from fingernails alone.


No cover, just straight up gorilla glass victus.

And it's not just key metal deposited on the screen, there are deep grooves cut into it.


I believe you, but there is some other explanation here- it warrants further investigation. You can scrape a regular glass window (about MOHS 6.5) clean with a razor blade (about MOHS 6.0) and it is impossible to scratch it, just from that tiny difference in hardness. I do this all the time, e.g. recently to get paint that my kid painted on the house windows off.

Your brass keys should only be about 3.0, and gorilla glass a 9.0- you should be able to rub keys into brass dust all day long and not mark the screen.

I store my keys right in my pocket with my glass iPhone SE, and it doesn't have a mark on it.

I suppose it is possible you have keys with some weird material or coating, or as another poster suggested- maybe something like an abrasive dust got stuck on your key.


Brass? Who said anything about brass?

Typical keys are made from nickel plated hardened steel and nickelsilver. Considering the shiny coating is long gone and the keys are ferromagnetic, I assume it's the first. The keys are certainly hard enough to scrape my glass ceramic stove.

And reports online say that gorilla glass victus is the mist scratch prone gorilla glass, scratching at or around 6 already :/


I think you may be onto something here. Taking apart old machinery I have often observed that the hardened part of a shaft is worn and has a noticable groove detectable with a fingernail. However the part that rubbed on it is often much, much softer eg a rubber oil seal. My theory is that the much softer material is so soft that microscopic inclusions of something much harder (grit?) are caught in the material and then abrade the harder shaft. Something similar may be occurring in the keys on glass case?


Cutting with a lubricant and grit is super effective. Silicon dioxide, that is sand, is everywhere.


Aren't both the lens and the screen are resilient to steel/metal scratches? I'm not willing to run keys or a knife over a phone on purpose.


Noticed this person didn’t want people to access the code for fear of misuse. Thankfully, someone else has already made this for flipper zero before them and released the code!

https://github.com/leedave/flipper-zero-meal-pager


<< Does this even work: I don't know. It's based on intel collected from other people. The Flipper sends data, I checked that with a second flipper. I've also heard rumors that it works in Australia. I'm sure it doesn't work in the US, as they use different frequencies. >>

I mean, that's helpful, but....


It would be kind of less interesting if they just figured it all for you and served it up on a silver platter don't you reckon? Where is your phreaking spirit at? :)

In the before computers times there was an ironically titled book called 'Steal This Book'.

Amongst a verity of other things it describes one of the funniest and most beautiful hacks I've ever heard of. I'm leaving this as a hint for others for fun or the rare cases that I know are on here that absolutely need to eat without money.

It requires one trusted accomplice and an all you can eat buffet. The rest is up to you to find out. It always works flawlessly and has for over half a century.


That book strongly reminds me of this review of "On the Road":

> On The Road seems to be a picture of a high-trust society. Drivers assume hitchhikers are trustworthy and will take them anywhere. Women assume men are trustworthy and will accept any promise. Employers assume workers are trustworthy and don’t bother with background checks. It’s pretty neat.

> But On The Road is, most importantly, a picture of a high-trust society collapsing. And it’s collapsing precisely because the book’s protagonists are going around defecting against everyone they meet at a hundred ten miles an hour.


Well observed. The very ending of On The Road itself addresses this if you read carefully, Kerouac did not lack in self awareness.

But then again he was a yuppie not a hippie trying to levitate the pentagon so that all the evil spirits fall out. ;)

And here we are where we are eh?


Kerouac aside, wasn't it the yippies (not yuppies) that were doing the Pentagon performance?

ISTR yuppies were years after the Youth International Party (and quite different).

Anyone?


Sorry I really bungled it up. Blame autocorrect and lack of coffee.

Meant to say Kerouac was a beatnik, Abbie was a yippie who inspired a generation of dirty hippies.

And we've sunk further still but I don't know that there is a lasting term yet. Maybe it will be NPC? I favor Quaranteenie (which makes less sense but sounds more fun, I mean by it a teenager who was locked up during their formative years and ended up a politically active mentally ill ignoramus)?


> Where is your phreaking spirit at?

You gotta keep in mind that there is a sizeable portion of any hacker culture that doesn't want to (or can't) do any part of the actual hacking that gets things figured out, but instead just want to use what was figured out in ways not intended by the original purpose of whatever was hacked. One might say the script kiddies of the physical side of things.

There are way more cooks in the kitchen than chefs.


To put it a little nicer, there's many skills encompassed by the title "hacker". There is no such thing as a universal jack of all trades hacker. Some are better at software, some are more comfortable in hardware. The RF hackers have a whole bundle of sub specialties.


This project looks very cool. Worth noting however that it doesn’t have tabs.


It has tabs on macOS at least, but it f alls in the classic pitfall of cross platform applications where they made the mistake of not using the OS to resolve keystrokes.

So my keyboard layout doesn't work with the app at all. I've identified the issues but making a pull request for it and testing it all is a bit of work I haven't gotten round to yet.


I just tried it and tabs are working at least on Mac.


Bad on mobile unfortunately. The CSS doesn’t wrap for portrait screens


To add to this, I think the toxic part about this is that SSRIs are the first line treatment, and are handed out like candy when they are not magic cure-alls for whichever ailment. In fact there’s a risk of SSRIs activating self-destructive mania, even in people who do not typically fall under the “bipolar” umbrella. (which, the interactions of SSRIs with undiagnosed disorders is also unsafe given their track record of being handed out like candy).


The GitHub link is helpful, it might be useful to include what each command does at the bottom of the page so users don’t have to go to the GitHub page to figure it out
