Sharp hacker. I learned about a few new layers in the hardware stack. I didn’t know that one memory cell could be manipulated from its neighbors either.
Maybe I’m just getting old, but the ‘freshness’ was over the top for me. I saw some of her early vids, and they were very nice and relaxed.

Can someone explain Laurie Wired to me? I see her in my recommendations sometimes, but I don’t click obvious clickbait.
Take this one, is it actually a design flaw or is it just a compromise that was made for good reasons and is kept around for those same reasons?
Maybe I’ll watch the video and report back, can always remove it from my watch history.

Its not clickbait, its a very deep dive. Her viseos are long because they explain stuff at a low level.

The title is objectively clickbait though, even if she does eventually explain the design flaw. But I think if she’s doing an hour on the history of RAM design, she could be honest about that.
This is probably a matter of taste, but I can’t sit through 58 minutes of slow buildup just to get to “ram has to refresh, that takes 300 nanoseconds sometimes, you could eliminate that at the hardware level by making all ram twice as expensive”
Thanks Laurie, but you don’t have to pretend all ram is fundamentally broken to make me watch an hour of maths and engineering. 3blue1brown does that all the time with titles like “What is a laplace transform?” and thumbnails of plain formulas on black backgrounds.

In those cases it’s less painfull to use a website to extract the transcript and read that.
You can skim around text way easier than a video.
TLDR: ddr ram refreshes itself, making cpus freeze sometimes when reading ram. High speed traders don’t want that so they figure out ways to make data live with two copies on two different portions of ram that freeze at different times. This is impractical for normal programs. Most of the effort is spent on working around multiple abstraction layers, where the os and then the ram itself changes where specifically data goes.
Then stuff about virtual memory management in modern OSs
physical ram address issues:
This also helps with rowhammer attacks where writing close to a physical address lets you write to that other address.
Goes on to write low latency benchmarks which show lower latency.

This was a super helpful comment! Thank you for sharing it with us. :)
What website do you use to extract a decent transcript, if you don’t mind me asking?

All of her thumbnails are literally: Photographing something you want to show to everyone

90% of thumbnails have a face in them, usually of an exaggerated strong emotion, and that goes for both male and female youtubers. Many youtubers have confirmed time and time again that the algorithm favors faces by a pretty wide margin, and thus most play that game.
I’m not a fan of it, I wish they didn’t, but I understand why they do. Though I don’t think it’s particularly gendered as your image claims.

jucky.
Also probably a function of the intended audience. Only happens when content farming stuff that hits a certain audience, and then it’s equally done by all creators. If you’re not an attractive woman you just put someone else in the thumbnail, like someone you interviewed, or if it’s game-related a character.
