In this guide, we’re going to demonstrate how to write and run the simplest script for tracking Ethereum wallet balance with GetBlock’s RPC API. What is Token Ownership? Token ownership is just a digital version of holding an asset. It is similar to holding stocks, currencies, or commodities like gold or silver. Each token is linked to an account (or wallet address), and the balance of tokens in that account reflects ownership. When you ac....

It’s been a little while since I introduced the Mgmt Configuration Language . I originally wrote this article in 2019, and as I was working on it alongside the code for functions, when I realized that lambdas didn’t work properly. It took some time to finally solve that properly. Since then I’ve been working to get mgmt production ready. It’s properly useful for production now, and so it’s time for me to catch up on my documentation. I’v..

I'm a fan of macOS's auto-hide menu bar setting. Unless I'm reaching out to a menu item, I don't typically need to have a visible menu bar, so I set auto-hide to "Always". On rare occasions, I turn this setting off (say for a screen grab ). While reaching out to macOS Control Center is OK, I wanted to quickly toggle it from the comfort of Emacs via M-x fuzzy search. We can leverage AppleScript to toggle the setting on and off. In th....

I love music. I love playing music. I love making musical instruments and music software. I don’t have formal musical training. I’ve never taken lessons, and honestly, I’m a pretty bad musician. What I do excel at, though, is hoarding musical instruments. At this point, name any instrument, and there’s a decent chance I have it somewhere in my room. Some of these instruments never played anything better than “Twinkle, Twinkle Little Star”, ..

Lately, I've been reading "Beyond Mach 3" ), Col. Buddy Brown's memoir of his years piloting the U-2 and SR-71 spy planes. If you like that sort of thing, it's an interesting read on its own, but it also has parallels to the software industry, particularly in the way it describes pilot workload. The concept of pilot workload provides a nice way to think explicitly about the burdens our systems place on us as engineers and operators to ....

Kent Beck has shared some good insights in his substack. If I have to start with something, this is probably it. This post takes a short and stingy look around real “aglileness” of software development. Short but quick deployments and closer feedback loops instead of long and drawn out processes. Because at the end of the day, there is one bug lingering only in production enviorment which is waiting to be revealed.

Since chatgpt-shell going multi-model , it was only a matter of time until we added support for local/offline models. As of version 2.0.6, chatgpt-shell has a basic Ollama implementation (llama3.2 for now). chatgpt-shell is more than a shell. Check out the demos in the previous post . For anyone keen on keeping all their LLM interactions offline, Ollama seems like a great option. I'm an Ollama noobie myself and already looking ..

Introduction: Welcome to Episode 6 of the Fearless Concurrency in Rust series! In this episode, we explore the powerful concept of ARC (Atomic Reference Counting) and its critical role in managing shared resources in multithreaded Rust programs. By leveraging ARC, developers can safely share ownership of data across threads without relying on a traditional garbage collector, enabling efficient, flexible, and scalable concurrency. What..

Should a programming language be powerful and let a programmer do a lot, or should it be safe and protect the programmer from bad mistakes? Contrary to what the title insinuates, these are not diametrically opposed attributes. Nevertheless, this is the mindset that underlies notions such as, “macros, manual memory management, etc. are power tools—they’re not supposed to be safe.” If safety and power are not necessarily opposed, why does t....
