Hacking

I am joining the ranks of self-proclaimed productivity experts: Do you feel distracted by social media? Do you feel that too much scrolling feeds transforms your mind - in a bad way? Solution: Go find an online platform that will put your mind in a different state. Go hacking on hackthebox.eu. I have been hacking … Continue reading Hacking

Infinite Loop: Theory and Practice Revisited.

I've unlocked a new achievement as a blogger, or a new milestone as a life-form. As a dinosaur telling the same old stories over and over again. I started drafting a blog post, as I always do since a while: I do it in my mind only, twist and turn in for days or weeks … Continue reading Infinite Loop: Theory and Practice Revisited.

Consequences of the Second Law of Thermodynamics

Why a Carnot process using a Van der Waals gas - or other fluid with uncommon equation of state - also runs at Carnot's efficiency. Textbooks often refer to an ideal gas when introducing Carnot's cycle - it's easy to calculate heat energies and work in this case. Perhaps this might imply that not only must the … Continue reading Consequences of the Second Law of Thermodynamics

Computers, Science, and History Thereof

I am reading three online resources in parallel - on the history and the basics of computing, computer science, software engineering, and the related culture and 'philosophy'. An accidental combination I find most enjoyable. Joel on Software: Joel Spolsky's blog - a collection of classic essays. What every developer needs to know about Unicode. New terms … Continue reading Computers, Science, and History Thereof

Ploughing Through Theoretical Physics Textbooks Is Therapeutic

And finally science confirms it, in a sense. Again and again, I've harping on this pet theory of mine: At the peak of my immersion in the so-called corporate world, as a super-busy bonus miles-collecting consultant, I turned to the only solace: Getting up (even) earlier, and starting to re-read all my old mathematics and … Continue reading Ploughing Through Theoretical Physics Textbooks Is Therapeutic

Learning General Relativity

Math blogger Joseph Nebus does another A - Z series of posts, explaining technical terms in mathematics. He asked readers for their favorite pick of things to be covered in this series, and I came up with General Covariance. Which he laid out in this post - in his signature style, using neither equations nor … Continue reading Learning General Relativity

Random Things I Have Learned from My Web Development Project

It's nearly done (previous episode here). I have copied all the content from my personal websites, painstakingly disentangling snippets of different 'posts' that were physically contained in the same 'web page', re-assigning existing images to them, adding tags, consolidating information that was stored in different places. Raking the Virtual Zen Garden - again. (Voice from … Continue reading Random Things I Have Learned from My Web Development Project

My Flat-File Database

A brief update on my web programming project. I have preferred to create online text by editing simple text files; so I only need a text editor and an FTP client as management tool. My 'old' personal and business web pages are currently created dynamically in the following way: [Code for including a script (including … Continue reading My Flat-File Database

On Learning

Some years ago I was busy with projects that required a lot of travelling but I also needed to stay up-to-date with latest product features and technologies. When a new operating system was released a colleague asked how I could do that - without having time for attending trainings. Without giving that too much thought, and having my … Continue reading On Learning

How to Introduce Special Relativity (Historical Detour)

I am just reading the volume titled Waves in my favorite series of ancient textbooks on Theoretical Physics by German physics professor Wilhelm Macke. I tried to resist the urge to write about seemingly random fields of physics, and probably weird ways of presenting them - but I can't resist any longer. There are different … Continue reading How to Introduce Special Relativity (Historical Detour)
