I think they are saying that their handheld radio/walkie talkie is interfering with their wireless dell keyboard. Which is pretty cool tbh. Maybe they can use it in reverse to sniff the key presses.

Open an honest question. Does the average off the shelf wireless data transmission chipset that all kinds of shit bag manufacturers just shove into their products... Do those by default broadcast on some split spectrum now or do they just kind of pick a band like old crappy RC cars lol

I really don't know. I am definitely not a radio expert.

Logitech uses 2.4GHz in their receivers, but I dont know how that coexists with wifi bands..

I would bet a lot of cheap keyboards still do the crappy RC car thing though.

I have something similar happen on my car. My phone is Bluetooth but because it's Huawei, it's not fully recognised. So when I send a voice message with Wechat, I see the car displaying a "phone call" to number 0000 as long as a keep the button pressed.

I'm wondering if this something similar going on here?

[–] CameronDev@programming.dev 1 points 2 months ago

I suspect not, given Bluetooth is packet based and includes checksums, so radio interference should result in corrupted packets that are ignored. That sounds like some kind of software bug/quirk?

What your CIA agent sees when you use vim

Is that a ligature for ;; ? What language uses that to mean something? 🤔

You might be thinking of Brainfuck.

Also, if you're going to search for that, MAKE SURE SAFESEARCH IS TURNED ON IF YOU'RE GOING TO SEARCH IMAGES!!

Hmm, the text does look somewhat like Brainfuck, but Brainfuck doesn't seem to use semicolons.

My question comes from the two semicolons on line 14 being pushed closer together. I assume the font has a ligature for when two semicolons are next to each other. Presumably, it's some coding font, which would also use ligatures to turn e.g -> into → and things like that.

But yeah, you don't usually include such ligatures into a font, unless there is a specific use-case for that. There could be a programming language that uses ;; to start a line comment, for example. But I'm really not sure, if I've ever seen that, hence my question. 🫠

Clojure for example

[–] Ephera@lemmy.ml 2 points 2 months ago

Aha! Seems to just be a convention to use multiple semicolons for full-line comments, but that's still probably it then.

Thanks! 🙂

That is interesting. They're definitely closer together on line 14 than on line 7.

C and C++ use for (;;) {} as an unconditional loop.

[–] Ephera@lemmy.ml 1 points 2 months ago

Ah, good point. Does make me wonder how the font developers test the effect of certain ligatures, like did they actually have both Clojure comments and unconditional C loops in mind when they introduced this ligature...? I guess, it doesn't really break anything, so could just introduce it and see if anyone complains.
