Deep Reflections

In the years between 2000 and 2005, I spent a lot of time trying out many different operating systems. Linux was a big one: Red Hat, Debian, SuSE. So also the BSD Unices: FreeBSD, OpenBSD, NetBSD. There was Solaris from Sun Microsystems. I also checked out MINIX (educational, from a CS prof), BeOS (good media support) and QNX (real-time OS). I tried dual- and multi-boot installations, also tried installing within VMWare. [Read More]

There’s a disparity in how our smartphones and computers cater to our senses. They rely heavily on the eyes and the ears. What’s left out is touch, smell and taste. Not strictly a sense, but scale of size is another I would add to this list – it’s the difference between looking at a T. rex in a museum vs a TV documentary. These can be a differentiator for brick-and-mortar stores.

I recently saw the movie The Father (2020) by Florian Zeller. It’s a poignant movie on the themes of aging and senility. Anthony Hopkins acts as the father who is losing memory, and along with it, a sense of what’s happening around him. To his family and us, it is abundantly clear, but the old man lives in a world of denial. What results is continuously escalating conflict, culminating in a moving climax. In this heartbreaking scene, the old father cries like a baby, and starts wailing “Mother! O Mother!” to the nurse who is caring for him. The nurse, instinctively, comforts him like a child.

Homebound in the pandemic, I purchased a bird-feeder last December. I’ve had a lot to observe since then. What follows are notes, photographs, and video clips. I conclude with tips and advice if you’d like to try it as well.

I am an engineer by profession but I like to read about psychology and psychotherapy out of interest. As I have become familiar with it, I’ve found it to be highly logical.

I will specify the system first, and then use it to make some suggestions for our improvement.

I originally started writing this in July 2021 but it took several revisions before I felt it was polished enough to post.

Hailstorms can pose a problem, if you’re installing solar panels. Large hailstones, those that are 2 inches wide or larger, can damage solar panels.

If you are solar panel provider, you typically want to play it safe and install where there has been no hailstorms, historically.

Sorry about that jargon soup, but this post is technical and is intended for such audiences.

I recently had an opportunity to speed things up by 10X:

I recently read Futureproof by Kevin Roose. Kevin is a technology writer for The New York Times. The book has two parts to it; I skimmed through the first part but found the second part interesting. It is a list of nine rules designed to help us, humans, navigate a world increasingly run by machines.

I want to call out four of them that struck me as very insightful.

I’ve previously talked about detecting irrigated croplands in this blog. I used classical machine learning techniques in it, i.e. we decide what features to use, we fit a model or an ensemble of models, we predict. Modern machine learning, or what the press calls “Artificial Intelligence”, has gone way beyond it. In this post, I want to talk about a different approach to detect irrigated croplands. This method gave 95% test-set accuracy on a random sample of 2000 pictures from California. [Read More]

Back in 2004, when I was in Bangalore and still fresh out of college, I was mesmerized by a book with a title that asked you to kill the Buddha if you met him. The murderous Zen title notwithstanding, the book was written by a psychotherapist who drew parallels between literary characters and his patients. I wanted to read more such books, but as I said, I was in India and it was 2004. Only in the last year have I delved deep again into the realm of psychotherapy.
