I get so frustrated with the idiotic thumbnails on youtube video these days. I am sure it's all optimized for the maximum number of clicks/views but if I see a still that looks the way it does at the bottom of this page I generally just don't watch it on principle.

Believe me, I had a nice discussion yesterday with my sister (who helped me take pictures for the thumbnail), and we both agreed it's one of the dumbest things about current YouTube... The thing is, from all my own A/B testing, a face vs. no face will automatically get 20-30% more views (all else equal). And an exaggerated face, a bit more than that.

That’s a crazy amount more!

I have a question about this. I don't use unencrypted storage and RPis have no hardware accelerated extensions. But modern SSDs do, and IMO it is good enough for some stuff even considering the issues. They call it Self Encrypted Disks but I don't know if this feature requires some BIOS specific instructions or special devices like TMPs or if there are special parameters one could pass to GEOM or LUKS to use those en…

The common standard for SED is TCG OPAL. This has a pre-boot image allowing you to enter your password. Once the drive is decrypted it is completly transparent with your unmodified bootloader and kernel loaded with normal commands. I don't think the RasPi can trigger this unlocking nor could be modified to.

* on boot. You can trigger the decryption of additional drives after boot.

Booo. Its just a pi with expensive ssd disks attached. Nothing interesting here.

Disagree. Plain Pi won't be able to attach 4 sata drives natively and is not a real alternative for actual NAS. This might be. Jeff does a lot of Pi-NAS testing and I'm thankful for that, as I find of the shelf solutions lacking a lot. Mostly software-wise. There is a huge demand for a simple NAS device that is not much larger then drives it uses, but doesn't have Qnap OS installed on it.

It has good network connectivity. 2.5G is a nice option for homelabs and actuall advanced home use.

The difference is the Radxa Taco board, which interfaces a CM4 directly with 5x SATA III slots, 1x native NVMe M.2 (2280), and 1x 2.5G NIC.

Most typical Pi 'server' builds slap all that IO on top of the Pi 4 model B's USB 3.0 bus.

I can't stand that Linus PC guy with his exaggerated faces on the thumbs.

I noticed that OPAL features are becoming less used in encryption software, because the keys to some drives can be dumped through their JTAG ports.

Really sad to see so many people dismiss this just based on the YouTube thumbnail at the bottom. Jeff consistently makes very high quality content, I really enjoyed his series on Kubernetes, I would urge you to look past any preconceptions there.

The fact is, if YouTube makes up a sizeable portion of your income, and that can increase by a factor of 10% just by making a dumb face, you’d be silly not to do so. It’s unfortunate that this is the way things work, but I can personally look past that to ensure that creators who provide value to me are able to put food on the table.

He's a video explaining how well that kind of clickbaity thumbs works.
