There is a lot of "who kills who" useless fluff, and everything to do with the wife is boring, but too much gold otherwise.
It is amazing to see how seasons got better and better until the finale. The last season was amazing, Ciro Santilli actually watched all episodes of that one! This is clearly seen on the evolution of metacritic scores.

Reviews mostly old RPG and strategy games. And hentai games when it is possible to hide the porn from YouTube. He also sponsors Hentai and uploads it on his website: www.ssethtzeentach.com/nsfw
Ciro Santilli really likes his sense of humor, always going into "politically incorrect" areas, and often making fun of both dictatorships and the USA. He actually knows a bit about politics. Due to the nature of his humour, many of his earlier videos have been taken down from YouTube apparently, www.ssethtzeentach.com/videos mentions:
Ever since going full time, I'm usually very clean and stay out of trouble, but in the past a fair number of my videos were taken down.
The videos are also incredibly packed full of well selected edited-in "memes jokes". He particularly likes very short snippets of gay porn which cannot actually be taken down as porn, even though the obviously are porn excerpts, like the buffed dude blowing a kiss to his tit.
www.youtube.com/watch?v=sw8v5__Ytf4 Heroes of Might and Magic III (2018) is one of the best reviews. Sseth likes to find and make fun of game breaking imbalances, something that Ciro likes due to his Ciro Santilli's self perceived creative personality.
www.youtube.com/watch?v=rOJdDvf-tUs The Sseth Streaming Experience (2019), being a live stream, likely shows more realistically how Seth actually talks in real life.
www.youtube.com/watch?v=yG9g2byXR2c Might and Magic VI (Re)Review is another good video (2021)
Sseth has a certain vaporwave aesthetic, which Ciro also enjoys.

Brownian motion Updated +Created
Small microscopic visible particles move randomly around in water.
If water were continuous, this shouldn't happen. Therefore this serves as one important evidence of atomic theory.
The amount it moves also quantitatively matches with the expected properties of water and the floating particles, was was settled in 1905 by Einstein at: investigations on the theory of the Brownian movement by Einstein (1905).
This suggestion that Brownian motion comes from the movement of atoms had been made much before Einstein however, and passed tortuous discussions. Subtle is the Lord by Abraham Pais (1982) page 93 explains it well. There had already been infinite discussion on possible causes of those movements besides atomic theory, and many ideas were rejected as incompatible with observations:
Further investigations eliminated such causes as temperature gradients, mechanical disturbances, capillary actions, irradiation of the liquid (as long as the resulting temperature increase can be neglected), and the presence of convection currents within the liquid.
The first suggestions of atomic theory were from the 1860s.
Tiny uniform plastic beads called "microbeads" are the preferred 2019 modern method of doing this: en.wikipedia.org/wiki/Microbead
Original well known observation in 1827 by Brown, with further experiments and interpretation in 1908 by Jean Baptiste Perrin. Possible precursor observation in 1785 by Jan Ingenhousz, not sure why he wasn't credited better.

On Ubuntu 20.10 PostgreSQL 12.6, login with psql on my default username without sudo fails with: stackoverflow.com/questions/11919391/postgresql-error-fatal-role-username-does-not-exist
This is the one that worked on Ubuntu 21.04: stackoverflow.com/questions/11919391/postgresql-error-fatal-role-username-does-not-exist/38444152#38444152
sudo -u postgres createuser -s $(whoami)
createdb $(whoami)
Explanation:
  • sudo -u postgres uses the postgres user via peer authentication
  • -s in createuser -s: make it a superuser
  • createdb: TODO why do we have to create a table with the same name as the user? Otherwise login fails.
You can now run psql without any password. This works without password due to peer authentication:
sudo cat /etc/postgresql/12/main/pg_hba.conf
shows that peer authentication is available to all users apparently:
local   all             postgres                                peer

# TYPE  DATABASE        USER            ADDRESS                 METHOD

# "local" is for Unix domain socket connections only
local   all             all                                     peer
List users:
psql -c '\du'
output:
                                    List of roles
  Role name  |                         Attributes                         | Member of

Delete user later on:
psql -c 'DROP USER username;'

(6 rows)
Delete a database:
psql -c 'DROP DATABASE "testdb0";'
If you didn't give a database from the command line e.g.:
psql
you can do that afterwards with:
\c testdb0
Let's create a table and test that it is working:
psql testdb0 -c 'CREATE TABLE table0 (int0 INT, char0 CHAR(16));'
List tables, no special tables:
psql testdb0 -c '\dt'
gives:
        List of relations
 Schema |  Name  | Type  | Owner
--------+--------+-------+-------
 public | table0 | table | ciro
(1 row)
View table schema: stackoverflow.com/questions/109325/postgresql-describe-table
psql testdb0 -c '\d+ table0'
output:

 Column |     Type      | Collation | Nullable | Default | Storage  | Stats target | Description

 char0  | character(16) |           |          |         | extended |              |
Insert some data into it and get the data out:
psql testdb0 -c "INSERT INTO table0 (int0, char0) VALUES (2, 'two'), (3, 'three'), (5, 'five'), (7, 'seven');"
psql testdb0 -c 'SELECT * FROM table0;'
output:

Delete the table:
psql testdb0 -c 'DROP TABLE table0;'

bsub get job stdout and stderr Updated +Created
By default, LSF only sends you an email with the stdout and stderr included in it, and does not show or store anything locally.
One option to store things locally is to use:
bsub -oo stdout.log -eo stderr.log 'echo myout; echo myerr 1>&2'
as documented at:Or to use files with the job id in them:
bsub -oo %J.out -eo %J.err 'echo myout; echo myerr 1>&2'
By default bsub -oo:
  • also contains the LSF metadata in addition to the actual submitted process stdout
  • prevents the completion email from being sent
To get just the stdout to the file, use bsub -N -oo which:
  • stores only stdout on the file
  • re-enables the completion email
as mentioned at:
Another option is to run with the bsub -I option:
bsub -I 'echo a;sleep 1;echo b;sleep 1;echo c'
This immediately prints stdout and stderr to the terminal.

Lab vs cyclotron X-ray crystallography Updated +Created
cyclotrons produce the better images, but they are expensive/you have to move to them and order a timeslot.
Lab-based just use some X-ray source from the lab, so it is much move convenient e.g. for a pharmaceutical company doing a bunch of images. The Wikipedia image shows such a self-contained lab system: en.wikipedia.org/wiki/File:Freezed_XRD.jpg
