Cool data embedded in the Bitcoin blockchain / Marijuana plant Updated 2025-07-16

Starting at tx 6650107a4e4e4838ba1081ce87862c38dcb4181b8d34fc0405b099213ba76033 (2014-11-04) and going on one line per transaction using the bitcoin blockchain j( upload system, there is a marijuana plant ASCII art:

j(-> 1EGa1izEFDHzEobDDQny73re9BwXdzhZvH <-
j(                 ,
j(                dM
j(                MMr
j(               4MMML                  .
j(               MMMMM.                xf
j(              "M6MMM               .MM-
j( h..          +MM5MMM            .MMMM
j( .MM.         .MMMMML.          MMMMMh
j( )MMMh.        MM5MMM         MMMMMMM
j(  3MMMMx.     'MMM3MMf      xnMMMMMM"
j(  '*MMMMM      MMMMMM.     nMMMMMMP"
j(    *MMMMMx    "MMM5M\    .MMMMMMM=
j(     *MMMMMh   "MMMMM"   JMMMMMMP
j(       MMMMMM   GMMMM.  dMMMMMM
j(        MMMMMM  "MMMM  .MMMMM(        .n
j(         *MMMMx  MMM"  dMMMM"    .nnMMMM
j(Mn...     'MMMMr 'MM   MMM"   .nMMMMMMM*
j(4MMMMnn..   *MMM  MM  MMP"  .dMMMMMMM""
j( ^MMMMMMMMx.  *ML "M .M*  .MMMMMM**"
j(    *PMMMMMMhn. *x > M  .MMMM**""
j(       ""**MMMMhx/.h/ .=*"
j(                .3P"%....
j(              nP"     "*MMnx

The transaction before the ASCII art tx 9b08c00ced2bca4525d74e82db9af2aec8ef213eb1c1bf68a48b6be929968332 starts with what is likely a "Legalize" and must be a Tor Onion service:

j(-> 1EGa1izEFDHzEobDDQny73re9BwXdzhZvH <-

but that address as is + .onion is invalid, TODO find the correct one.

Other marijuana plants can be found contained entirely in single transactions:

While learning black-hole stuff is not on top of Ciro Santilli's priorities, Hawking's spirit is to be admired.

To never give up even when everything seems lost, and still have a sense of humour is respectable.

An ex-physicist colleague who had met Hawking told an anecdote. Hawking was around in the department one day, they said hi and all. But then Hawking wanted to tell a joke. It took like 5 minutes of typing, and you can imagine that things were pretty awkward and the joke's timing was "a bit off". But Hawking did tell the joke nonetheless.

This is also suggested in the The Theory of Everything (2014) film, and therefore likely the biographies.

E. Coli Whole Cell Model by Covert Lab / Output overview Updated 2025-07-16

Run output is placed under out/:

Some of the output data is stored as .cpickle files. To observe those files, you need the original Python classes, and therefore you have to be inside Docker, from the host it won't work.

We can list all the plots that have been produced under out/ with

find -name '*.png'

Plots are also available in SVG and PDF formats, e.g.:

PNG: ./out/manual/plotOut/low_res_plots/massFractionSummary.png
SVG: ./out/manual/plotOut/svg_plots/massFractionSummary.svg The SVGs write text as polygons, see also: SVG fonts.
PDF: ./out/manual/plotOut/massFractionSummary.pdf

The output directory has a hierarchical structure of type:

./out/manual/wildtype_000000/000000/generation_000000/000000/

where:

wildtype_000000: variant conditions. wildtype is a human readable label, and 000000 is an index amongst the possible wildtype conditions. For example, we can have different simulations with different nutrients, or different DNA sequences. An example of this is shown at run variants.
000000: initial random seed for the initial cell, likely fed to NumPy's np.random.seed
genereation_000000: this will increase with generations if we simulate multiple cells, which is supported by the model
000000: this will presumably contain the cell index within a generation

We also understand that some of the top level directories contain summaries over all cells, e.g. the massFractionSummary.pdf plot exists at several levels of the hierarchy:

./out/manual/plotOut/massFractionSummary.pdf
./out/manual/wildtype_000000/plotOut/massFractionSummary.pdf
./out/manual/wildtype_000000/000000/plotOut/massFractionSummary.pdf
./out/manual/wildtype_000000/000000/generation_000000/000000/plotOut/massFractionSummary.pdf

Each of thoes four levels of plotOut is generated by a different one of the analysis scripts:

./out/manual/plotOut: generated by python runscripts/manual/analysisVariant.py. Contains comparisons of different variant conditions. We confirm this by looking at the results of run variants.
./out/manual/wildtype_000000/plotOut: generated by python runscripts/manual/analysisCohort.py --variant_index 0. TODO not sure how to differentiate between two different labels e.g. wildtype_000000 and somethingElse_000000. If -v is not given, a it just picks the first one alphabetically. TODO not sure how to automatically generate all of those plots without inspecting the directories.
./out/manual/wildtype_000000/000000/plotOut: generated by python runscripts/manual/analysisMultigen.py --variant_index 0 --seed 0
./out/manual/wildtype_000000/000000/generation_000000/000000/plotOut: generated by python runscripts/manual/analysisSingle.py --variant_index 0 --seed 0 --generation 0 --daughter 0. Contains information about a single specific cell.

College puffer jacket Updated 2025-07-16

E.g.: thecollegestore.co.uk/products/ladies-oxford-college-puffer-jacket?variant=40590030864549 Black with 5 rows, on left chest "colege name", logo, "Oxford", and right chest optional initials (or sometimes other identifiers/nicknames) to help distinguish from all the other people's identical clothes.

This has a whitelabel version: www.workweargiant.co.uk/product/result-urban-holkham-down-feel-jacket/, the name appears to be "Holkham Down Feel Jacket".

Circa 2020, these are likely given out by each college for free, and are widely used.

If you look 20 and wear one of those, it's almost an ID, you can get anywhere that does not require a key card, porters won't look at you twice!
