Embedded Files
week by week summary of my career over the year.
I will try to blog each whenever possible, whether it is programming, or something related to electronics or music and audio.

Binnacle 2024
February / March 2024. Decided to go back to Paris.
November / December 2024. I came back to Montevideo for a month for a family visit, but finally I will move to Paris.
It is rather important to me to keep a continuous flow of information as it were a bonfire on my head. I would like to keep exercising and practising engineering problem-solving, in order to not lose it on the daily routine of maintenance firmware development.

I got into trying to run shadertoy shaders on my GPU through a Python script. It was pretty easy to have it running following the guide in here: https://www.youtube.com/watch?v=wPOw5jK-Jn8

Cuestionar tu cerebro respecto a sensaciones, emociones y tu yo y tu sistema de creencias para recalibrarlo a una realidad más factiblemente chequeada.
Por ejemplo: miedo al frío, ir a la ducha fría para ver, comprender y saber que no te pasara nada,
ir a correr cuando pensas que estas cansado para ver que podes subir esos umbrales de cansancio, disconformidad y dolor.
Esto sería como ejercitar el músculo del cerebro respecto a lograr objetivos y superar metas y pequeños logros. Y también cambiar tu estado de ánimo o tu actitud frente a distintas;
sensaciones, emociones y predisposiciones.
Quizas yo deberia dejar de predisponerme tanto a que mi trabajo va a ser esperar y no tener interaccion con nadie del equipo. Cada vez que logeo a la maquina se que ella va a estar con la pantalla vibrando y siendo todo muy insoportable. Que las meetings son inutiles. Etcetera, que no me dan bola cuando opino y no se hacen los cambios que a mi me gustaria que se hagan en el code-base y en la metodologia.
Todo esto son predisposiciones que acarreo conmigo cada vez que logeo, es una masa, es mucha data y negatividad especialmente. Hay que ir mas ligero, mas armonico, relajar los musculos las ideas, ir abierto, cuestionar todas mis predisposiciones para llevarla mejor en el dia a dia.
Suponer que los demas tambien logran cosas y tienen sus propios objetivos y creencias. Suponer que los demás siempre tienen buenas intenciones. Alegrarse por el trabajo y esfuerzo bien logrado de los demás.
"Si lo consigo todo seria practicamente una desgracia. "
No estaria en la vida
No podria ser compasivo con los demas me veria obligado a pensar y sentir que los demás son unos paquetes que no consiguen nada de lo que quieren.
La compasión es un pilar gigante del vivir contento y cultivar la alegria y la felicidad. Es necesaria.
"Mimetizarse con el entorno, mas armonicamente, entiende las personas que están a tu alrededor, y trata de integrarte a equipos y distintos grupos, superando tus miedos por pertenecer."

April 3rd 2024. Following others.
Today I found two different blogs from graphics R&D developers that I would like to save and follow from here on.
Blog about different C++ techniques, memory management awareness.
Tricks and tips working with floating point numbers.
I should mention the readings I did on RTK technologies for GPS positioning with centimeter accuracies. It is a very interesting topic for a DIY project for my portfolio. The idea came from another job interview.
I saw that he follows different blogs created by other developers, this was one of them and I found that he's got a lot of insight and some remarks about using ChatGPT professionally.
Debugging C++ on MacOS Visual Studio Code
Keep up with interview solving puzzles with C/C++ running directly on PC/Mac.
Here my take on the pattern searching question I failed to get done in time.
https://github.com/fcarraustewart/c-training
Robin Williams interviews are cool.
Art and humanity. I am very interested and in awe of the use of language, communication and articulate transmission of knowledge.
Other gentle souls.
I am reading Norman Davies' History of Europe which is a massive book and he talks about very smart informative concerns from historians and artists and poets, in english.
Also reading LoTR 1: with very cool unseen scenes and also a very smart english use by Tolkien.
Also reading Healthy Gamer, by my zen master. Psichology and Communication tricks for others and the self.

Mind
Trataka, or fix-point staring, meditation 20 minutes, or 10 minutes series spread throughout the day to keep stress and distraction at bay.
Candle staring and just wall staring are also possible scenarios.
No real need for a gym membership yet, but that would have helped with the change of scenery at Home Office.
Just getting out for a coffee and a walk every odd day.
Cleaning a room first thing in the morning helps a lot with infinite negativity loops or weird loops in the head.
April 2nd 2024. Routine slowly building.
Body
Yoga stretch in the morning, daily, and cardio 20 minutes or walk.
Sometimes strength exercising up to exhaustion; push-ups 2 days a week.
Daily ones helps to keep warm throughout the day while sitting down so much.
Cold shower if you can to practice discomfort. We don't want Wall-E's humans.
