Fourier transform Updated 2025-07-16
Continuous version of the Fourier series.
Can be used to represent functions that are not periodic: math.stackexchange.com/questions/221137/what-is-the-difference-between-fourier-series-and-fourier-transformation while the Fourier series is only for periodic functions.
Therefore, the Fourier transform can be seen as a generalization of the Fourier series that can also decompose functions defined on the entire real line.
As a more concrete example, just like the Fourier series is how you solve the heat equation on a line segment with Dirichlet boundary conditions as shown at: Section "Solving partial differential equations with the Fourier series", the Fourier transform is what you need to solve the problem when the domain is the entire real line.

Frederick Sanger Updated 2025-07-16
Ah, this seems like a nice dude.
The Eighth Day of Creation has two nice paragraphs about his work. He was shy and quiet, and didn't boast about his slow and steady progress, possibly because of this he only had a junior fellowship and at some point some people wanted to kick him out of the lab somewhere between 1948 - 1952, quoted at: sandwalk.blogspot.com/2013/11/fred-sanger-1918-2013.html
Business film Updated 2025-07-16
Ciro Santilli defines a "business film" as a film about business, enterprises or entrepreneurship. Political thrillers are closed related as well.
This is one of his favorite film genres!

No open signup it seems. TODO CV of owner.
They are making a proof assistant to integrate into the website: github.com/bookofproofs/fpl/, reminds Ciro Santilli of website front-end for a mathematical formal proof system.

Bo Ya Updated 2025-07-16
en.wikipedia.org/w/index.php?title=Bo_Ya&oldid=1150295883#The_story_about_Zhiyin:
Bo Ya was good at playing the qin. Zhong Ziqi was good at listening to the qin. When Bo Ya's will was towards high mountains in his playing, Zhong Ziqi would say, "How towering like Mount Tai!" When Bo Ya's will was towards flowing water in his playing, Zhong Ziqi would say, "How vast are the rivers and oceans!" Whatever Bo Ya thought of Ziqi would never fail to understand. Bo Ya said, "Amazing! Your heart and mine are the same!" After Zhong Ziqi died, Bo Ya broke his Guqin because he thought that no one else can understand his music.
Brazil Updated 2025-07-16
An awesome country, with amazing people and natural resources, and without an evil government like China.

Brazilian Student Association Updated 2025-07-16
This is a good initiative. Since the government is incapable of doing shit in this area, individuals have to do it themselves.
They even have a scholarship program...: www.bolsas.gobrasa.org/
Breadboard Updated 2025-07-16
This is how electronic circuits are normally prototyped!
Once you validate them like this, the next step is usually to move on to printed circuit boards for more reliable production setups.
Breadboards are a thing of beauty and wonder.

. Source. Predecessors to breadboards from where the name came. A thing of beauty, so vintage. You could actually write stuff on those with a pencil!

Source. bsub get job stdout and stderr Updated 2025-07-16
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:as documented at:
bsub -oo stdout.log -eo stderr.log 'echo myout; echo myerr 1>&2'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 as mentioned at:
bsub -oo:To get just the stdout to the file, use
bsub -N -oo which:- stores only stdout on the file
- re-enables the completion email
Another option is to run with the bsub This immediately prints stdout and stderr to the terminal.
-I option:bsub -I 'echo a;sleep 1;echo b;sleep 1;echo c' bsub on foreground Updated 2025-07-16
Run Ctrl + C kills the job on remote as well as locally.
bsub on foreground, show stdout on host stdout live with an interactive with the bsub -I option:bsub -I 'echo a;sleep 1;echo b;sleep 1;echo c'; echo done There are unlisted articles, also show them or only show them.
