Figure 1. Source. Good image from Wikimedia Commons. In this one we can see how the blades are put vertically, and you get several of them per horizontal rack space, instead of a tipical single rack server going all the way horizontally.

HP Blade Server by Brian Kirsch (2013)
Source.
In the video we can see that it contains RAM, disk storage, we are told about two CPUs, and networking interfaces, so it is a complete computer on its own. He also explains that unlike typical rack servers, each blade unit does not have its own coolers and power supply related hardware, which goes instead on the chassis.

Cool data embedded in the Bitcoin blockchain / 503: Bitcoin over capacity Updated +Created
Starting tx a87d406fae047258a12923b3c11a797a5765bd8f868df5c7e9b1cead0e92c9c1: the message:
503: Bitcoin over capacity!
appears about 13 thousand times. WTF happened?
Cool data embedded in the Bitcoin blockchain / Illegal content of block 229k Updated +Created
These can be viewed at bitcoinstrings.com/blk00052.txt and are mostly commented on the "Wikileaks cablegate data" section of Hidden surprises in the Bitcoin blockchain by Ken Shirriff (2014).
Soon after block 229991 uploaded the Satoshi uploader, several interesting files were added to the blockchain using the uploader, and notably some containing content that might be illegal in certain countries, as a test to see if this type of content would make the Bitcoin blockchain illegal or not:
So basically, this was the first obviously illegal block attempt.
None of this content is particularly eye-popping for Ciro Santilli's slightly crazy freedom of speech standards, and as of 2021, the Bitcoin blockchain likely hasn't become illegal anywhere yet due to freedom of speech concerns.
Furthermore, it is likely much easier to find much worse illegal content by browsing any uncensored Onion service search engine for 2 minutes.
Ciro Santilli estimates that perhaps the uploader didn't upload child pornography, which is basically the apex of illegality of this era, because they were afraid that their identities would one day be found.
