Hello all,

I'm trying to get into GUI programming, but am hesitating on using a Python library to make my first barebones program. My goal is to code basic buttons and understand how operating systems implement the way they draw windows for applications.

I have coded mostly in scientific libraries or high-level languages that are fairly simple (Python, Matlab, Julia)... Also am familiar with basic concepts and syntax from C.

Looking for recommendations to start. I am happy to learn a new PL. Interested in writing code for legacy hardware and mobile. Bonus if the codes are general enough to be written for most displays one could interact with.

 

Hi everyone,

I am in the midst of troubleshooting why my fans are not turning on despite the PC booting.

The motherboard is an MSI x670e gaming plus WiFi. The CPU cooler is a Noctua NH-D15 with two fans.

Things I have tried or will try so far…

  1. Update bios version… (y) Didn’t fix anything.
  2. After BIOS update, see if changing power setting to PCM turns the fans on. (n)

All the connections are slotted in properly, so I’m not sure what’s the matter with the system… Mint is already installed, so it’s weird that none of the fans turn on. Including the GPU.

This is my first Linux build out of the box… Should I be looking for any drivers in particular?

CPU: Ryzen 5 7600x GPU: Radeon RX 7800

Hey Everyone,

I'm very happy to see the engagement in my last post... Hoping to improve my communication skills and reduce my verbosity in the next couple of discussions.

I feel like it is due time to follow-up on what I posted on this board last year. That is, to follow through with "full-stack" hardware-software-application study groups.

If any of you still are interested, I'd like to open up this form for discussion of how that group should be run.

On the subject of HDLs (Hardware Description Languages), VHDL (Verilog HDL) could be fun for some of us to try together. Architecture is also a large concept frequently glossed-over, enciphered with too much jargon, or taught in a very "academic" fashion with very little discussion between students... The traditional classroom model, from what I experienced, is not too conducive to neurodivergent learning styles.

On that note, the RISC-V processor architecture could provide an amazing opportunity to gain a low-to-high understanding. Starting from the Silicon, where we delve into unit operations for chip manufacturing, fundamental solid state / condensed matter physics, and some mathematical models to describe the underlying phenomena. Then we will proceed to what can actually be configured in the ensemble of devices that constitute your "computer". What is a "piece of logic"? How do transistors actually operate? Why do certain design topologies make more sense than others...? And so forth.

We would conclude with some software projects like writing an I/O driver for a keyboard, or pool a fund together for some type of chip we design in EDA together. Overall, it sounds like a great idea for us all to increase our technology literacy, have a fun hobby group to hang out with, and to feel like you own every part of your computer.

On top of this, I feel that we should discuss FOSS tools with each other, as well as how they are best implemented to accomplish common tasks. I've punted the majority of my "Big Tech" stack to the curb the last 5-ish years.

TUI tools as well as CLI interaction is a paradigm of computer operation that I feel many of us have been sleeping on. It also has helped me understand how GUI applications can be better suited for the task at hand, versus when I should be using a terminal emulator to navigate the directory hierarchy instead. Many of you are more versed in programming than I am, so I would love to hear your thoughts.

We could even come up with a project for mobile, who knows? Not sure about the format, whether or not this would be synchronous, and the time commitment and sustainment of motivation throughout a probably 8 week period. However, I feel like a realistic solution for us all to get something meaningful out of an experience like this exists.

Any thoughts on how to get this up and going? What would we need to do on our first meeting together? What things would you want to learn in this course? It seems to me that many of us are already quite literate in sub-domains of what we are interested in. Maybe a teacher carousel routine could be adopted? Where we adopt a general "roadmap" curriculum, and, in an ad hoc fashion, assign people to be the instructor for the desired lesson? Then that person could go and create a slide deck in Beamer, or prepare a presentation with an overhead camera or digital drawing device to use as a teaching medium.

Those are just some ideas. Really looking forward to hearing what all of you think about this.

 

Hey everyone,

I've noticed this community is a bit barren. I'd like to add some posts myself but from a more ignorant POV.

It has come to my attention that there is not nearly enough software torture in my life. Hearing how companies are starting to add barriers to so-called "Translation layers" and other software pieces that give functionality to the underlying hardware...

What types of projects does the open source community need to pursue with respect to RISC-V drivers, firmware, or other necessary pieces to somewhat guarantee that the processor is compatible with GPUs, RAM, I/O, and other low level functions that hardware components perform?

Where should I start in my RISC-V journey? Is there a beginner computer or developer kit that I can purchase that won't incinerate my wallet? I don't expect to game or train LLMs off of a RISC-V-based computer, but am curious as to what a fully free hardware setup would consist of.

Love the idea of RISC-V!
