lol ok you got me, I had to look up whether they had designed it so badly
Yeah, but will that last 20% require exponentially increasing amounts of co2 production until life on the planet is destroyed and thus ensuring the supply won’t be exhausted?
Has anyone actually used a qr code for anything useful?
When they were first becoming a thing, i used them to buy bus tickets but it was more of a novelty than anythingI think they're awesome. They're an optical, better version of barcodes. I'm sure there's a bunch of specific industrial use cases. What's cool about them is the error correction so you can do stuff like this where the middle is carved out. There's also a standard way of sharing Wi-Fi networks as QR codes, so you could have a QR code of your home Wi-Fi network SSID/password to share with guests instead of having to dictate it to them.
QR codes were invented as a way to trick graphic designers to put blotches of static on things
if anything they seem to be getting more popular recently. Restaurants have QR codes on the tables now for accessing menus, many countries use QR codes for Covid passes, lots of countries use a QR code digital signature for government form authenticity. Seems like they might have gotten their start for making purchases in Asia or a gimmick on a bus stop poster but they're used for a bunch of things now.
I use them pretty regularly to quickly open a webpage I have open on a desktop browser on a smartphone, by using an extension that generates a QR code of the URL
It's very commonly used in "developing" countries like China and India for payments cuz most cheap smartphones don't have NFC
Sharing multi-factor authentication secrets and transmitting small bits of information from a computer to a smartphone are their primary use cases for me.
SQRL (Secure Quick Reliable Login) is a password-less authentication protocol developed by GRC that's awesome and uses QR codes if you use a smartphone SQRL client, but it'll probably never catch on.
We have a printed one at my work to get clients to follow without having to do the whole searching through ig thing
And we put them on cards to hand out at shows in my band when we perform
And plane/concert tickets here and tbere
another fun fact
all music encoded in lossy formats such as mp3 before 2009 has degraded into a virtually unlistenable state
for each year the MP3 sits on your hard drive, it will lose roughly 12kbps, assuming you have SATA - it's about 4kbps on SSDs, due to rotational velocidensity.always encode your music in lossless formats like FLAC only download FLAC music dont listen to streams that dont deliver FLAC they will lose their quality
NGL this kinda sounds bullshit, unless you're reencoding or compressing the file over and over I don't think magnetic orientation errors or general entropy leads to that much degradation. At worst a few bits get flipped and a CRC fails or something. But also in the process of typing this I realized this might just be a bit and I'm making this comment for nothing idk. :shrug-outta-hecks:
Yeah regardless of the hardware side, lossy vs lossless compression has nothing to do with losing data over time, even if you use lossless very high quality encoding if the data's getting corrupted it doesn't matter if it wasn't compressed, you're losing the data.
for each year the MP3 sits on your hard drive, it will lose roughly 12kbps, assuming you have SATA
Heard this can also vary depending on whether your SATA is 1.5/3/6 Gbits/sec as well as the age of the drive (platter spin speed and whatnot) - in general I recommend just keeping the "two in the bush one in the air" adage in mind. personally I like to have physical music, and then FLAC copies on my personal PC & mirrored onto my NAS!
Godspeed! :rat-salute:
(Nobody fall for these trolls, I have no idea what the technical literacy rate is on this forum)
Frank record data. Frank use stone tablet. Stone tablet not degrade on human time scale. Stone tablet not ideal from data density perspective. Stone tablet have long read and write times. Stone tablet cause silicosis of the lungs during write process.
