Q: Python case insensitive dictionary

@JeremyThille The question is a very bad fit for Code Review. There is no code in the question, and the user hasn't asked for a review of a project. — Peilonrayz 35 secs ago

I got an interesting e-mail, although as I'm not that much of a regular these days I thought I would post it here and see if anyone of you might be more interested.
Hi Simon,

I'm Cian, a Math student from Ireland currently partaking in Patch.

An idea we thought about pursuing is a platform for code reviews. Naturally, I happened upon CR.SE!

Originally, this left us feeling like what we were building was a simple duplication, and therefore not that useful. However, after reading Code Review is getting boring and Can
 reviewing be made more efficient we're not so sure.

So I guess I have two main questions for you as a moderator and active member of the CR.SE community.
(Links have been omitted, but this is the Patch they are talking about)
If anyone is interested, I can forward the mail to you.
 
@SimonForsberg Interesting, I'm guessing Patch is like Google Summer of Code. So Cian needs to write a little project. I'll have a more in-depth look later.

@Duga I think is AI. However rev1 is potentially off-topic... :/ We can rollback to rev1, close the question, rollback to rev2 and then reopen the question leaving us where we are now. Bit messy

There may be a better way than what you are doing. If you show what you have so far, odds are good we can make suggestions, but that's not really the point of Stack Overflow. If you have code that word but you believe it could work better, you should ask at Code Review. I strongly recommend reading through their help pages on asking questions first so you can formulate a question that will be well-received. If your code doesn't work, that's what we do here. Show it and we'll help fix it. — user4581301 22 secs ago

@Peilonrayz You sure there's no animal in side?
 
@skiwi No, not sure. If there is, do you think a treated make the animal play ball?
 
@Peilonrayz I prefer top line or almost top line consumer audio. I do need to figure out how to add a Raspberry Pi for streaming.
 
I've been considering hooking up a Raspberry to my TV for audio and multimedia streaming for, oh, years now.
The newer ones seem to have in-built support for booting from USB so you're not relying on iffy SD hardware.
Bad experiences with SD and micro SD cards are one of the reasons I'm not using my Raspberries enough, I'm working on fixing the other reasons. Apparently I haven't fixed enough of them yet...
 
7:23 PM
@pacmaninbw Just looked up the difference. I probably got consumer audio. What kinda streaming are you looking at?
Oh, after reading Mast's message I'm assuming like Plex/Chromcast. Never done anything like that on Linux ):

@Peilonrayz @Mast and I are considering the same thing. I'm thinking about getting rid of cable and just streaming movies using NetFlix or HBOMAX. $10 a month versus $115 a month.
Problem is my download speed is only about 30M.
 
@pacmaninbw I think Netflix allows you to download content for a period of time. So you can download and then 'stream' the content. May want a bit of a chunky SD card however :) Or get the rpi4 which has an m2 slot
 
I have 2 RPI4s. I'm actually planing on downloading to an external HD with 8TB and connecting that using USB.
 
Ah, I see you're way ahead of me :)
 
Does your audio equipment connect to the net?
 
No, I got a mixer and a mic. How come?
