I've said this before, but it's interesting to see momentum go back and forth between the flexibility and ease of everyday language, and the formal rigor of programming languages.

It feels like we are still discovering the optimal operating range on a spectrum between these two domains. Perhaps the optimal range will depend on the specific field in question.

There was an interesting article in the Atlantic recently where a journalist spent a year participating in sports gambling. Part of the article discusses the effect it had on his psychology towards participants he had put his money on.

Sports is one thing, but the potential for threats / intimidation towards news reporting, politics, etc. is a huge concern.

The author of the Airfoil article has made several similar tutorials on various topics:

For machine learning, Distill.pub has some excellent hands-on tutorials. For example, here's one on momentum:

Octave has not implemented all of Matlab's functionality. You can see a list of Matlab functions that have not yet been implemented in Octave at the link below. It's a long list.

Matlab is an great tool, if you can afford it.

It was a very unpleasant feeling when I graduated from my PhD and realized that most, if not all, of the Matlab scripts I had used for my research would now be useless to me unless I joined a company or national laboratory that paid for licenses with the specific toolboxes I had used.

I'm glad that a significant portion of tools in my current field are in open source languages such as Python and Julia. It widens access to other researchers who can then build upon it.

(And yes, I'm aware of Octave. It does not have the capabilities of Matlab in the areas that I worked in, and was not able to run all of my PhD scripts. I have not tried RunMat yet, but am looking forward to experimenting with it.)

This is apparently such a common misunderstanding that it was put at the bottom of the C++ iceberg:

One of my students recently came to me with an interesting dilemma. His sister had written (without AI tools) an essay for another class, and her teacher told her that an "AI detection tool" had classified it as having been written by AI with "100% confidence". He was going to give her a zero on the assignment.

Putting aside the ludicrous confidence score, the student's question was: how could his sister convince the teacher she had actually written the essay herself? My only suggestion was for her to ask the teacher to sit down with her and have a 30-60 minute oral discussion on the essay so she could demonstrate she in fact knew the material. It's a dilemma that an increasing number of honest students will face, unfortunately.

Buzz Aldrin (who was the second person to walk on the moon) wrote his MIT thesis on methods for astronauts to handle the complexities of orbital dynamics when performing rendezvous maneuvers in orbit:

Very curious to see what usage limits are like for paid plans. Anthropic was already experiencing issues with high-volume model usage for Pro and Max users. I hope their infrastructure is able to adequately support running these additional coding environments on top of model inference.

Just to be clear, I'm excited for the capability to use Claude Code entirely within the browser. However, I've heard reports of Max users experiencing throttled usage limits in recent months, and am concerned as to whether this will exacerbate that issue or not.

Science involves both deductive and inductive reasoning. I would in turn argue that mathematics is a science that focuses heavily (but not entirely) on deductive reasoning.

Yes, Julia has a few options for making executables but they feel like an afterthought.

Interesting tips, but it also depends on the field.

If you're submitting to a control theory journal, you better have some novel theorems with rigorous mathematical proofs in that "rest of the paper" part. That's a little nontrivial.

"The Wright Brothers" by David McCullough - Shows how Orville and Wilbur surpassed the leading researchers of the day to be the first to achieve controlled, powered flight. Does a great job of describing their work ethic and research process.

"The Myths of Innovation" by Scott Berkun - Not exactly about how hard things got done, but it discusses some of the misconceptions and assumptions we make about current technology and the process of inventing new tech.

It's fascinating how phones have come full circle. One of my first cell phones had a full QWERTY keyboard with physical keys that was exposed when you slid the top face of the phone sideways. Many phones in that era had similar full keyboards.

The fact that the iPod touch, iPhone, iPads, and other surface devices didn't need physical keys was seen as more modern and desirable at the time. Now it looks like people are circling back around and wanting physical keys again.

History moves in a helix I guess.
