Earlier quoted context omitted.

I built pianojacq.com to help me practice sightreading and to keep track of where I'm making mistakes. It is still far from perfect but quite useful. The main problem is to get the pieces I want to practice into MIDI format, but there is a wealth of MIDI files out there that can be used with a little editing. I have this pipeline where I take a youtube video, download it as an MP3, convert that to MIDI and then edit…

Piano has also been my go to this pandemic. I've also been finding a lot of joy in applying my programming skills to music as well. What are you using to convert MP3 to MIDI? How accurate is it?

Either this: https://piano-scribe.glitch.me/ or my own cobbled together piece of software. Depending on the content anywhere from 80 to 95% accurate, good enough to get you started and typically the errors are reasonably easy to deal with because of repeating patterns.

I am going through SICP. I have just begun. I am learning more about Transformers architecture and modern NLP using the Hugging Face API. Building a computer from scratch using nand2tetris on Sundays. Learning to meditate following a detailed meditation guide. This has been working better than I expected. Going on and off with learning classical music online (with a piano). Learning German. I am primarily focused on…

Those are a lot of things to be learning at once, I'm impressed you're keeping up with all that. Do you mind if I ask what your time management looks like? I'm curious how many hours you spend a week on this stuff, and how much of you free time it takes up. I also like to learn a lot of different things on the side but I struggle to find time for everything that I want to cover.

Well, I will have to write many paragraphs to fully understand your questions.

Let me tell you that I am highly unsuccessul as a piano player. I cannot play much more than a few simple "pieces". Becaue I am highly irregular.

And apart from work and reading SICP, I don't do everything everyday. I read SICP 7 days a week. But work only five. No Deep Learning on Sundays. On Saturdays, no work, only personal learning, reading papers, attending study groups, etc.

Actually I can work for no more than five hours a day- proper, hard work, "deep work" if I may.

I want to extend that to 8/10. That is my main motivation behind meditation. I am better than most in concentrating during learning and work. I just want that to last for longer hours.

I studied Electronics and Computer Architecture (from the Mano book mostly) before, so I don't find nand2tetris very challenging. It is fairly challenging at times, but not the hardest thing that I do. It's more fun than challenge.

SICP is challenging at times. But I spend time with it very regularly, say 1-2 hours a day.

I have learned from my experiences that, when you are learning something fundamental, new, it is best to learn it over many days and months rather than bouts of short sprints.

So, I am regular with it, but don't spend long hours.

Being with a highly career focused partner helps a lot, too.

I discussed my time management techniques here-

I spend 30 or so minutes every day reading novels, poetry or about the culture and history of the Bengali people.

I also exercise regularly.

I like to swim, but pools are closed.

Managing outsourced content writers. I’m building up the side hustle gradually to escape the soul-sucking grind of the day job, and being a good manager of an outsourced team will allow me to take things to the next level.

what are you working on? I'm interested in hearing more!

After nearly 13 years out of it, I picked up a 3D printer. I did a fair amount of printing and modeling in my last years of college, but since transitioning into programming not long after graduation it's been something that I hadn't had the time for, or the avenue to apply it. So far I've had more failed prints than successes over the last week or two, but I'm still excited to be doing it. I'm learning the ins and o…

The main thing is to level the bed. Once you do this, it shouldn't require releveling except maybe every 1-2 months.

Upgrade the bed to the glass bed. Get yourself some hairspray and spray the bed every few prints. You'll never get failed prints again.

Learning the basics of Computer Vision and Image Recognition via Machine Learning by following along with this book: "Learning OpenCV 4 Computer Vision with Python 3: Get to grips with tools, techniques, and algorithms for computer vision and machine learning" by Joseph Howse, Joe Minichino - 2020, Packt Publishing available here (library genesis): http://libgen.lc/item/index.php?md5=9208FA33E5C1F93918E128F8...

Thanks for the book recommendation. I've also got a machine vision project I've been meaning to tackle one-of-these-days, and hopefully this will be enough of a nudge to get me started!

Piano. I've decided that more programming languages or web stacks are a complete waste of time. Piano is for life and I wished I had started doing this in earnest long ago.

I've been astounded by the number of free pianos I see on Facebook marketplace. I totally get the allure (and used to play a bit myself), but I fear it's a dying art.
