Several other interesting uploads were also made around block 318836 (September 2014):

This seems to be a novel work uploaded by its creator artist Allen Vandever according to EMBII.[ref].
Arecibo_message.svgArecibo message on tx c6d2e535cd2ba4659e954a61198c66fd98c60f6475cf8ff92a404f3fe3a16c4b, block 337874 (2015-01-07)
An "artificially" colored visualization of the Arecibo message ripped from Wikipedia: en.wikipedia.org/wiki/File:Arecibo_message.svg (with attribution).
The cool thing about this image is that it highlights the striking parallels between the encoding of the Arecibo message with crypto graffiti, because in both cases people were creating undocumented new ways of communicating with strangers on a new medium in those early blockchain days.
The associated message contains the Arecibo message as ASCII 0's and 1's. When properly cut at the newlines, they draw the message as ASCII art, as the original Arecibo encoding intends, here's a version with the 0's replaced by spaces to make it more readabale:

The image is present e.g. at: www.kitguru.net/channel/jon-martindale/australian-man-claims-he-is-satoshi-nakamoto-bitcoin-creator/ It was inscribed about two months after Craig publicly claimed that he is Satoshi.
This is a relatively unusual AtomSea & EMBII upload as it does not have the common toplevel transaction, everything, text + image fits into a single transaction. This is perhaps why the image is relatively low resolution to have a smaller size.

The associated message reads:This is one of Ciro's favorite AtomSea & EMBII uploads. This is the cutest thing ever, and perfectly encapsules the "medium as an artform" approach to blockchain art. More Chiharu stalking at: ILoveYouMore.jpg.
Chiharu and I found this little yellow robot while exploring Chicago. It will be covered by tar or eventually removed but this tribute will remain. N 41.880778 E -87.629210
At twitter.com/EMBII4U/status/1615389973343268871 EMBII announced that he would be giving off shares of that image on a Bitcoin-based NFT sale system he's making called Sup!?, and in December 2023 gave 2/300 shares to Ciro Santilli. Amen. The transaction list can be seen on the web UI at: p2fk.io/GetObjectByAddress/1KUyhHLrK1ckY8W7Qu31h6gFkXoihWHMzi?mainnet=true&verbose=true It had unfortunately never sold as of 2025, the only activity was EMBII giving off some shares and two listings of 1/300 for 1 BTC. Poor EMBII!

Good animation explaining it: Video "Electron transport chain by HarvardX (2017)".
In x86 systems, there may actually be 2 address translation steps:like this:
- first segmentation
- then paging
(logical) ------------------> (linear) ------------> (physical)
segmentation pagingThe major difference between paging and segmentation is that:
- paging splits RAM into equal sized chunks called pages
- segmentation splits memory into chunks of arbitrary sizes
This is the main advantage of paging, since equal sized chunks make things more manageable by reducing memory fragmentation problems. See also:
Paging came after segmentation historically, and largely replaced it for the implementation of virtual memory in modern OSs.
Paging has become so much more popular that support for segmentation was dropped in x86-64 in 64-bit mode, the main mode of operation for new software, where it only exists in compatibility mode, which emulates IA-32.
Peter Cordes mentions that some architectures like MIPS leave paging almost completely in the hands of software: a TLB miss runs an OS-supplied function to walk the page tables, and insert the new mapping into the TLB. In such architectures, the OS can use whatever data structure it wants.
It is quite mind blowing that this is polyphyletic on mammals and birds, what can't parallel evolution achieve??
For students (who are paying for the university to start with...), they will not claim tutorials linked to courses. But a tutorial that shows university laboratories, it is unclear: www.ox.ac.uk/students/academic/guidance/intellectual-property (archive) This likely includes graduate students, who are also not paid by the university.
For faculty, the university owns everything it seems, to be confirmed.
The closest site of the University of California to San Francisco. Berkeley, California is a small town on the East of the San Francisco Bay.
Brother of andrew the Apostle, called by Jesus in fishers of men. Born Simon, but Jesus renamed him to Peter, thus the weird "Simon called Peter" way he is referred to as in some versions of the Bible.
Ciro Santilli's joke version of the Chinese Four Treasures of the Study!In the past, Ciro used to use file managers, which would be the fourth tresure. But he stopped doing so for years due to his cd alias... so it became three. He actually had exactly three windows open when he was checking if there was anything else he could not open hand of.
- web browser
- Text editor
- terminal. Though to be honest, circa 2022, Ciro learned of the ctrl + click to open file (including with file.c:123 line syntax) ability of Visual Studio Code (likely present in other IDEs), and he was starting considering dumping the terminal altogether if some implementation gets it really really right. The main thing is that it can't be a tinny little bar at the bottom, it has to be full window and super easily toggleable!
The three Treasures of the Programmer
. Featuring: Gvim, tmux running in GNOME terminal, and Chromium browser on Ubuntu 22.04. The minimized windows are for demonstration purposes, Cirism mandates that all windows shall be maximized at all times. Splits withing a single program are permitted however.Examples at svg/background.html which answers from stackoverflow.com/questions/11293026/default-background-color-of-svg-root-element/11293812:
- svg/background-rect.svg
- svg/background-viewport-fill.svg: was part of SVG 1.2, but that whole standard got dropped. Not implemented neither in Chromium 85 nor Firefox 93 as of 2021.
This pain reflects directly on Inkscape: set SVG background color in Inkscape.
