What do I do in my situation? I feel like being in despair. I feel like I don't have any other options. Clearly, this situation feels like suicide for my career.
I was recently diagnosed with ASD, bipolar disorder type 2 and depression, for what it's worth.
markhollis | 5 years ago | on: Ask HN: Learning about philosophy
https://existentialcomics.com/blog/1/How_to_study_philosophy...
I like courses or philosophical works, which focus on a common themes, common threads. That allows one to see more connections across different thinkers.
One instance of this is John Vervaeke's Awaking from the meaning crisis (which isn't only philosophy, but also cognitive science).
Other courses like that are those from John Searle (philosophy of language, philosophy of mind).
Hubert Dreyfus has a course on existentialism in literature and film.
Thinking of it, there is also a channel called Like Stories Of Old. The maker publishes video-essays, which are often philosophical in tone and reference existential thinkers like Kierkegaard.
My own journey into philosophy started with Wittgenstein (apart from an introduction in Greek Philosophy in high school).

markhollis | 5 years ago | on: Who Is Alexander Grothendieck? (2008) [pdf]
Some resources I have used are:
* video lectures by Richard Borcherds
* Lecture notes by Andreas Gathmann (https://www.mathematik.uni-kl.de/~gathmann/class/alggeom-200...)
* This blog: https://rigtriv.wordpress.com/ag-from-the-beginning/
* An infinite large napkin, by Evan Chen (https://venhance.github.io/napkin/Napkin.pdf)
It also found it helpful to learn some (algebraic) number theory, to get a sense of where some of the motivation comes from (e.g. elliptic curves, modular forms). Grothendieck's work is abstract, but he was always motivated by concrete problems (e.g. Weil conjectures).

markhollis | 5 years ago | on: Logic, Before ICs
However, when you need to repair ICs on a PCB, you need a specific IC doing your function, which you may not have in stock. I wondering why the argument doesn't apply for transistors. The assumption seems to be that it doesn't matter much which transistors are used.
I don't know if anyone can validate what my colleague is saying.

The hard part is not the ventilation mechanism itself, but the specifications. Those ventilators must be controlled precisely, they must take into account the characteristics of COVID-19 patients. There is some overlap with ventilation for ARDS. The more you read into this subject, the more you realize how absolutely scary it is to actually design such a project. Lots of parameters have to be taken into account.
Read on mechanical ventilation. https://en.wikipedia.org/wiki/Mechanical_ventilation
3D printed parts that where the air flow through must be air-tight.

Continuous mandatory ventilation (CMV) is required, however it is necessary to accept permissive hypercapnia.
