When receiving unsoliciting phone calls by telemarketers, many people consistently hung up, don't bait, and don't interact. So why don't telemarketers delete from their databases such phone numbers that don't lead to any sales or other business benefits?

Maybe the cost of keeping the numbers is so low telemarketers just don't bother. Or keeping track of what numbers to delete may actually have a cost. Or perhaps telemarketers hope those people will eventually pick up the calls.

Any insight?

Can you recommend any screen video capture tools compatible with Wayland? I’ll use such a tool on my Raspberry Pi 400 under 64-bit Raspberry Pi OS Bookworm, so I'd prefer one with appropriate Debian binaries.

Update

VokoscreenNG is a screencasting tool that works with Raspberry Pi OS, I tested it on my Pi 400. And it's also easy to install, just sudo apt install vokoscreen-ng gstreamer1.0-pipewire.

Most washing machines have a timer that prevents you from opening the hatch just after the washing cycle ends. Instad you must wait for the timer to go off, usually a minute or two, before you can open the hatch.

Why? Would letting the user open the hatch immediately after washing ends pose any safety or other issues?

Se passate in un bar nel pomeriggio o verso fine giornata noterete che in genere sono avanzati dei croissant integrali al miele, con marmellata ai frutti di bosco, o di altri tipi ma sepolti dallo zucchero a velo.

Questo non sorprende perché probabilmente sono i tipi di croissant meno richiesti dai clienti. Quello che sorprende è che ne avanzino così tanti.

Questa situazione viene notata dai gestori dei bar? Perché non provano a ordinare qualche pezzo in più dei croissant più richiesti, per esempio quelli alla crema o alla marmellata di albicocche, e qualche pezzo in meno di quelli meno richiesti?

Avete qualche ipotesi o esperienza diretta, specialmente se lavorate in un bar o nella ristorazione?

An informal newsletter in which Thorsten Ball, of Writing an Interpreter in Go and Writing a Compiler in Go fame, shares his thoughts about software engineering.

If you contact the customer support of your utility company, phone carrier, bank, or other service provider you'll likely be flooded with requests to rate the experience and provide feedback. Likewise, corporate websites and email communications often solicit feedback via embedded buttons or links to online forms.

What's with this corporate obsession with customer feedback?

Are these huge piles of feedback actually analyzed and acted upon? Is customer feedback some sort of corporate cargo cult? Or maybe clever marketing by vendors of feedback tools and services?

The impression is the feedback is just discarded or ignored.

Feel free to comment here and/or on the linked Hacker News thread.
