2019-08: www.amazon.co.uk/dp/B000LFRYG2 (archive) "Silverline SP1236 Combination Spanner, 8-19 mm - 12 Pieces" 8.48 pounds. Because I needed the 15mm for bike pedal, and the price of 1 and the full set were very close.

Python (programming language) Updated +Created
Examples under python.
Ciro Santilli's wife was studying a bit of basic Python for some job interviews, when she noticed:
Wow, in is so powerful! You can do for x in list, for x in dict and if x in dict all with that single word!
Damn right, girl, damn right.
Ciro remembers hearing about Python online briefly. It seemed like a distant thing from the Java/C dominated (and outdated) university courses. Then some teaching assistant mentioned during some course when Ciro was at École Polytechnique that Python was a great integration tool. That sounded cool.
Then finally, when the École Polytechnique mathematics department didn't let Ciro Santilli do his internship of choice due to grades and Ciro was at an useless last moment backup internship, he learned more Python instead of doing his internship job, and was hooked.

Suwu herding sheep Updated +Created
www.ibiblio.org/chinese-music/html/traditional.html contains an amazing orchestral version for di flute TODO identify! When attempting to upload to YouTube, it identifies as "Su Wu Tending the Sheep" and give a name "Chen Tao", but no further information. Chen Tao is presumably this dude: www.barduschinamusic.org/chen-tao-dizi | www.melodyofdragon.org/chentao.html 陈涛
baike.baidu.com/item/苏武牧羊/5532#11_2 mentions that it comes from an erhu concerto composed by Peng Xiuwen
The sadness of the erhu perfectly fits the role and mood of the story! Brilliant!

There is value in tutorials written by beginners Updated +Created
Ciro Santilli is a big believer that there is value in tutorials written by beginners, because beginners are more likely to explain things in a way that other beginners can understand.
Even though they make more mistakes, this more approachable point of view can be very valuable.
And mistakes/omissions can be corrected on comments by people with more knowledge, so that the writer also ends up learning something new.
By other people:
  • jakobschwichtenberg.com/about/ from Jakob Schwichtenberg mentions quotes C. S. Lewis book "Reflections on the Psalms"[ref]:
    It often happens that two schoolboys can solve difficulties in their work for one another better than the master can. [...] The fellow-pupil can help more than the master because he knows less. The difficulty we want him to explain is one he has recently met. The expert met it so long ago he has forgotten. He sees the whole subject, by now, in a different light that he cannot conceive what is really troubling the pupil; he sees a dozen other difficulties which ought to be troubling him but aren't.

CIFAR-10 Updated +Created
60,000 32x32 color images in 10 different classes: airplanes, cars, birds, cats, deer, dogs, frogs, horses, ships, and trucks.
TODO release date.
This dataset can be thought of as an intermediate between the simplicity of MNIST, and a more full blown ImageNet.
Tcl Updated +Created
One of the first big interpreted programming languages to go a bit further than Bash' word replacement insanity.
To the modern viewer, it feels like a middle ground between Bash and Python.
It was completely insane however, and it just died: Python is much saner, and Bash, although totally insane still golfs better, especially on the file manipulation context.
Wireshark capture filter Updated +Created
Capture by instead:
sudo wireshark -f http -k
sudo wireshark -f icmp -k
Filter by both protocol and host:
sudo wireshark -f 'host 192.168.1.102 and icmp' -k
For application layer capture filtering, the best you can do is by port:
sudo wireshark -f 'tcp port 80'
There is an http filter but only for as a wireshark display filter

AMD just gave up this risky part of the business amidst the fabless boom. Sound like a wise move. They then fell more and more away from the state of the art, and moved into more niche areas.

John Thompson's Guqin website.
Holy crap amazing list of Guqin pieces by the guy for MP3 download! www.silkqin.com/06hear.htm And the explanations are insane. What a dude. Ciro Santilli's hero.

Ciro Santilli Contacted John by email in 2019 telling him to put his stuff on YouTube and offering help, and he replied, but nothing came of it unfortunately. Edit: he uploaded a bunch of videos of him playing live in 2020! www.youtube.com/user/silkqin/videos
John focuses on playing the tunes in a "historically informed performance", in particular using silk strings rather than metal ones which are used by most modern artists: www.silkqin.com/08anal/hip.htm
