I flat-out refuse to do business with any that requires I use an app. I won't even scan a QR code for a restaurant menu; that's my cue to go eat elsewhere.

[–] [email protected] 7 points 8 hours ago

Worst thing about qr menus for me is that when I finally order, I have to give my phone number and address. Bro, I'm sitting across from the kitchen and just want dumplings. Why I gotta dox myself for that?

I don't mind the whole online menu thing. It's probably an environmental net positive, but it's bs if they don't have ANY physical copies for those who can't or don't want to for whatever reason.

If they wanted me to install something, though, that'd be a 100% instant nope.

I mean I simply refuse to as QR code phishing is a thing

[–] [email protected] 7 points 14 hours ago (2 children)

You might enjoy SecScannerQR then. It makes it easier to vet QR codes by giving an option to search for the URL instead of going there directly.

Isn't that standard behavior though? I've never seen anything that opens a URL directly instead of just showing it to you with an option to access it.

An online menu requires power to be used (on people's phones and the server). Is that really a minor contribution in comparison to printing paper and maybe laminating it?

[–] [email protected] 24 points 20 hours ago (4 children)

Considering your average printer is a piece of shit that needs to be replaced quite often, yes, using a website is probably more energy efficient.

[–] [email protected] 1 points 1 hour ago

Generally companies use service contracts to keep those things working so mo they wouldn’t be replaced often. They are just a piece of shit

[–] [email protected] 12 points 16 hours ago (1 children)

That and those servers are going to be running anyway. Powering a simple restaurant website is a grain of sand on the beach of internet usage.

[–] [email protected] 8 points 13 hours ago

Yeah, exactly. If you're worried about the power draw to host a few hundred KB PDF file, you probably shouldn't be using Lemmy, because scrolling through your feed probably uses 100x that in energy costs.

You have to remember that the shared hosting or aws, or wherever is going to be cheapest to host a simple website is also going to be very power efficient. Wasting power is just throwing away free money, and if there's one thing corporations don't do, it's throw away free money.

Most companies will be using laser printers, some of which may outlive me. Toner is cheap and lasts an age.

Inkjet printers are cheap for a reason. They’re a scam.

This person has never seen the power bill for running a high-availability server with several failovers once in their lives.

[–] [email protected] 3 points 16 hours ago* (last edited 15 hours ago) (1 children)

In fairness neither have I - though I suspect it's not as insignificant as others have claimed.

[–] [email protected] 6 points 16 hours ago (3 children)

It's not insignificant at all. Servers are beefy and take more power than a standard PC... a lot more. Further, failover servers mean you have to have exact copies of the same server up and available, which means you're doubling, tripling, quadrupling power demands. Finally, you also have to have Uninterruptible Power Supplies, those take an amount of power as well.

It's a huge power draw. I know because I have a bunch of low-power devices runnig 24/7 as microservices and it still increase my power bill and use by a lot. I regularly get letters from the power company about how I'm using like 3x the power of the average person in my type of unit.

  1. You can host a webserver on a Raspberry Pi. I don't know what you're doing with your setup but you absolutely do not need hundreds of watts to serve a few hundred KB worth of static webpage or PDF file. This website is powered by a 30 watt solar panel attached to a car battery on some guy's apartment balcony. As of writing its at 71% charge.

  2. An Ampere Altra Max CPU has 128 ARM cores (the same architecture that a raspberry pi uses), with a 250 watt max TDP. That works out to about 2 watts per core. Each of those cores is more than enough to serve a little static webpage on its own, but in reality since a lot of these sites get less than 200 hits per day the power cost can be amortized over thousands of them, and the individual cores can go to sleep if there's still not enough work to do. Go ahead and multiply that number by 4 for failover if you want, its still not a lot. (Not that the restaurant knows or cares about any of this, all this would be decided by a team of people at a massive IT company that the restaurant bought webpage hosting from).

I'm also using a lot of self hosted things but have never received any of those.

Where do you reside generally where they're sending them because it ain't a thing here in the UK?

[–] [email protected] 4 points 15 hours ago* (last edited 15 hours ago) (1 children)

US, west coast.

It's not meant to make a person feel attacked as much as gently nudging them to use less power.

Pretty sure its even automated.

[–] [email protected] 4 points 15 hours ago

I don't think I'd feel "attacked" but more impressed that I came to light if they sent me them very much like a naughty "copyright warning" and would send it back with a brick in it.

Cheers!

[–] [email protected] 2 points 15 hours ago

I had not considered that an uninterruptible power supply would be consuming power after charging. I suppose no electronics are 100% efficient at what they do.

I've been playing with a Proxmox server on an ITX system for local services and rare game hosting for friends. I'd love something low power I could have on all the time.

Scan QR code. Order on your phone. Pay on your phone. Asks for a tip.

So uh, what exactly am I tipping you here for dawg?

[–] [email protected] 8 points 16 hours ago (1 children)

that stuff is nice as an option. There's a bar I go to that I can order my food and drink to the table my friends are at, while I'm walking to the place, and everything just arrives shortly after I sit down. Other people get offended about how fast I get served, it's always amusing. I also enjoy not interacting with the staff, nothing against them, brain just doesn't brain sometimes.

But what if I didn't have a phone? or if I left home without it? 24/7 pocket rectangle is not natural.

[–] [email protected] 6 points 13 hours ago

Losing your phone now is like losing not just your wallet but simple access to everything.

The funny thing about qr codes for restaurant menus to me, as someone that studied menu design. Is that actual menus are designed specific ways make the restaurant more profit and make it easier for people to find what they want. Whereas qr codes often bring one to a hastily designed list of categories which are not only less intuitive but also less manipulative. So people will end up taking longer to order less profitable dishes.

[–] [email protected] 7 points 16 hours ago

Hell yeah, consumer win. I like selecting an item and it offers me changes or addition options that I never would have considered!

But really, it means they can hire less people so they gain profit anyway.

Dennis Takes a Mental Health Day is probably the most accurate portrayal of me ever written.
