A few years ago, to better understand ray tracing, I read the book Ray Tracing in One Weekend. The original code samples were in C++, and as I read, I was translating and writing them in Python. Yes, I knew from the start that it was a terrible idea, but I was curious. One of the best ways to observe Python’s performance inadequacy is to test the ray tracing algorithm by generating an image with a width of 1000 pixels. But even 300 pixels takes a lot of time. Therefore, you resort to altern...| Gökmen Görgen
I took a quick look at the new features in Python 3.14. To try the code below on your local machine, install uv and run the REPL with the following command: uv python upgrade 3.14 uvx python@3.14 PEP 750: Template Strings Template strings (t-strings for short) were a proposal to address a significant shortcoming in existing f-strings, and it’s now ready for use with version 3.14.

I assign a minimum lifespan to things I want to own. This habit helps me calculate how much budget I can allocate for them, understand whether that thing comes cheap or expensive, and whether it’s worth it. My 6-year-old Alienware laptop was a bit of a disappointment for me. I wanted it to be something I could game on at home, code on, and also be my portable computer. I also wanted to be able to increase RAM and SSD capacity when needed in the future. None of my expectations were met satis...| Gökmen Görgen
I had the experience of upgrading Python in the projects from 3.8 to 3.12 in one step, and I realized that keeping the Python versions up to date is just as critical as keeping the dependencies up to date. Maintenance should not be a separate task, it should be part of all the other tasks. If you can check and update package versions in a timely manner, you don’t have to tell anyone that it’s going to hold up your business in the future.| Gökmen Görgen
17 years ago, Steve Jobs stood on stage with a manila envelope in his hand and pulled out a laptop. At that time, mini-laptops called netbook were very popular, and the first Macbook Air had far superior features in every way. I had a Lenovo IdeaPad S10e. If I remember correctly, the screen resolution was 1378x768, but it was good enough for me. It fit in my small bag, it was light, and I could open it up and even use it on the food tray on my long bus rides.| Gökmen Görgen
Sometimes I see this photo when Apple announces a new product and there are some really funny jokes about it on social media. Frankly, I don’t understand the criticism that “Apple is exhausted, it can’t produce anything new” for technological products that have reached a certain maturity. How do you compare them?

When dealing with more than one language, we look for similar approaches across languages. In Rust, there’s a keyword called enum to define and use enumerations. It’s easy to use, let’s look at this example from the official document: enumIpAddrKind { V4, V6, } structIpAddr { kind: IpAddrKind, address: String, } let home = IpAddr { kind: IpAddrKind::V4, address: String::from("127.0.0.1"), }; let loopback = IpAddr { kind: IpAddrKind::V6, address: String::from("::1"), }; If we want to wri...| Gökmen Görgen
Python favours letters and meaningful keywords for the logical operators, and all of them return a value depending on the conditions: not: The opposite of a condition, the reverse of the logical state of its operand. If the condition is True, it returns False, or vice versa. and: It needs to compare two operands, It returns True if both operands are True. or: It’s similar to and, but it returns True if at least one of the operands is True.| Gökmen Görgen

This isn’t advice, but I’d like to share what I did to get my daughter interested in coding. Like any parent, I showed her all sorts of things to learn coding at a young age, it was zero curiosity. After a while I couldn’t understand why I had done this, I just put it on the shelf and let her do whatever she wanted, I just watched and expected her to ask for something.

As I mentioned in my last post, I started using VSCode to see what I’m missing and I thought that it’s a good time to take all the risks and break my Emacs configuration.

I’ve used Emacs for years, and it’s not easy to get rid of this archaic (what?) editor. Although it helped me do my job better, my setup was not as stable as in the editor.

Mostly I do not prefer to read the books written for teaching a programming language.

I use PEP8 in my Python projects except for a few rules. I think ‘single-quote’ and “double-quote” characters should NOT be the same. It could be better if these two characters had different counterparts in the Python language parser system. So we could use one of them for the template-strings (or f-strings). It doesn’t provide readability, causes inconsistency instead. Until now, I used string-quotes for the variable definitions and double-quotes for the visible texts. But now,...| Gökmen Görgen
