I’ve written a long tutorial exploring the user of Racket’s Concurrent ML (CML) inspired concurrency paradigm to write an API wrapping git-cat-file. It is meant to serve as an introduction to kill-safety and CML concurrency, while assuming some existing knowledge of Racket or other Schemes. I found that there weren’t a lot of resources beyond the reference documentation that explained how to put these APIs together, and I hope this can fill..

Once you learn a little elisp , Emacs becomes this hyper malleable editor/platform. A live playground of sorts, where almost everything is up for grabs at runtime. Throw some elisp at it, and you can customize or extend almost anything to your heart's content. I say almost, as there's a comparatively small native core, that would typically require recompiling if you wanted to make further (native) mods. But that isn't entirely true. Ema....

This post is the part of trading series. In the past, I gave you a brief intro to Ta-Lib and how it can be used in technical analysis, in this post, I am going to discuss how you can RSI indicator to generate buy or sell signals in Python by using the TA-Lib library. Before I write code about the implementation, let’s discuss a bit about signal generation and RSI. What Are Signals In the world of trading, signals are cues or indicators that....

Andrej Karpathy has a very well-done Intro to Large Language Models video on YouTube. As a founding member and research scientist at OpenAI and with a two-year hiatus working on Tesla Autopilot, Karpathy is an authority in the field. He is also good at explaining hard things. As a Kahneman reader, I appreciated the Thinking Fast and Slow analogy proposed at about half-length in the video: “System 1” (fast automatic thinking, rapid dec..

Text Embeddings: Speaking languages without learning them? tl;dr : some *-en models perform well on other languages too.

Liked: Implement Custom Tramp Method in Emacs As expected, everything in Emacs is very customizable, including custom transport handlers in tramp and even custom completions for tramp.

In a few days, on Monday, December 4, at 10 a.m., I will present at the .NET Conference Italia 2023, which will be held at the Microsoft House in Milan. My session is titled “C#12 What’s new and interesting” and is part of a rich agenda focused on the recent release of .NET 8. I presented on the same subject at a DevRomagna meetup a few months ago when C# 12 was in preview and still had several moving parts. Now that the final release..

I finally decided to hang up a shingle on itch.io. My first app there is not a game. Lua Carousel is a lightweight environment for writing small, throwaway Lua and LÖVE programs. With many thanks to Mike Stein who helped me figure out how to get it working on iOS, this is my first truly cross-platform app, working on Windows, Mac, Linux, iOS and Android. repo Carousel has its own devlog/notebook. I try to post little scripts tha..

The Raspberry Pi has been the most popular single board computer (SBC) among computer hobbyists for the past decade. It can be used to perform a wide variety of very different tasks, such as running graphical apps, streaming media, performing home automation, and monitoring humidity levels in a greenhouse. This is largely made possible by the Raspberry Pi’s many interfaces (including GPIO, USB, HDMI, and wired/wireless Ethernet), as wel..

Introduction This year I set a personal goal of walking for a total of 1,000 kilometers and I’m proud to say I’m close to hitting that goal. I’ve been tracking all the different routes I take in an app named Strava . One nice feature of Strava is that the app provides access to the raw data in a format called GPX . Starva can visualize the route in their app, but I wanted to try and perform my own visualization. That brought me to this b..

Hi, Nach fast zwei Jahren ohne Release ist es am Samstag endlich so weit. Bei einem meiner Kunden wurde seit zwei Jahren nicht released - Wahnsinn 🤯 Warum? Viele Gründe. Das Team hat sich in Komplexität verrannt. Es wurden große (notwendige) Änderungen vorgenommen. Diese hatten aber viele Seiteneffekte. Und der Anspruch war alles “richtig” zu machen. Es wurde also immer weiter entwickelt. Mit einem abgeschlossenen Thema kamen ..

I’m on Fedora 37 at the moment. My headphone audio is backwards. How do we fix it? I’ve apparently never found the right magic until now. The Setup : I have a crappy “couch computer”. It’s used for casual internet browsing and video watching. It has an analog audio out which goes to my speakers. I’d like to use headphones for when I don’t want to annoy my neighbours. I have a pair of wireless headphones that I got for free, but the..
