I write posts and try to do them daily or at least weekly. Check out my site (tristanxr.com) for my latest posts. I often write about topics like ARM, RISC-V, NixOS, and things I am interested in or involved in.

@BrianSpragge Yes but no, there's a bit more logic with how GCC walks for headers.

wait, so If I put my headers in /usr/local/include/name-of-lib then I do not need to -lname-of-lib when compiling? g++ just figures it out.

@Shreyassanthu77 It's done that way to be more efficient in terms of memory. State is what needs to persist across rebuilds. Base is used as a form of inheritance.

@RossComputerGuy More specifically are there any constraints to not using the Counter directly instead of having a magic state structure inside with a magic base field inside? Is that a limitation of zig or are you just going for the state ful widget - state pattern to be close to flutter?

The source code of the counter app. The way the UI framework works is inspired by Flutter.

Threw in a new NVME to replace the ADATA in my desktop before going to Portland in a couple days. Glad to see the media errors going away. ZFS is doing its black magic to replace a drive.

Found out that some of my DIMM's were running at 95C and causing my Ampere system to lock up due to the high heat during very heavy Nix builds that are sustained. Made a post on the Ampere forums so others can try some of the stuff I did to help mitigate this kind of problem. community.amperecomputing.com/t/preventing-h…

@aethei7v Hardware is the thing now

Why are so many people liking my FPGA post? 🤔 Did they change the algorithm?

@vxunderground I remember hearing that your DM's are just cats and malware and I ended up contributing one of my cats.

Welcome to my DMs

@cyclopsmeza @ericlu Well it is right for the video on the website since the one on Twitter isn't easily downloadable.

@RossComputerGuy @ericlu that’s not what it says bot

I created a font called Ghost Font that only humans can read. Tested it in Fable and GPT 5.6 Sol Ultra and neither was able to decipher it correctly.

@__alula I shove it in a microVM

you guys don't supervise clankers at all times and manually approve all commands if you give them access to your computer?

@Shreyassanthu77 It's for a stateful widget.

@RossComputerGuy Interesting Why the phantom state thingy? can I see how it's implemented?

@PsychogenicTech Oh you're going to Teardown? I'll be there covering declarative hardware.

You can design your own chip. This month. With a laptop. → Teardown Portland — in person workshop → Worldwide online premiere — with live Q&A The Hello World of chip design: it's tons of fun :) Online: tinytapeout.com/online-workshop Teardown: crowdsupply.com/teardown/portl… #tinytapeout

@jrxcket That's pretty smart of them to do. I wonder how much of freedom those wires have to move in case the rocket isn't exactly that precise when coming down.

The Chinese method of catching boosters using the wires is actually kinda cool lmao

@ayoubElMhamdi It's actually a nice language. It's a good middle ground between C and Rust. It's not a memory safe language but you can write memory safe code. The build system being just a Zig program that allows you to do just about anything is nice.

@RossComputerGuy awful language too

I love Cashies, most of the store is random junk, tools and cameras, then you sometimes come across something hilarious like a laptop with a very a early gen Intel chip, a firewire port, e-sata, an rj-11 port and a full cd drive

@OSdev_ Yep soft interrupts and hard interrupts are different.

One of the biggest operating system myths is that system calls are just interrupts. They aren't. A system call is a controlled transition from user mode to kernel mode that lets an application request a privileged service, such as reading a file, allocating memory, creating a process, or sending data over the network. The CPU switches to the kernel through a dedicated mechanism designed specifically for system calls. On modern x86 processors this is typically done with the SYSCALL/SYSRET instructions, while ARM64 uses the SVC (Supervisor Call) instruction. A hardware interrupt is different. It is generated asynchronously by hardware devices, such as a timer, keyboard, SSD, or network card, to notify the CPU that something needs attention. Interrupts can occur at almost any time, independent of what the currently running program is doing. Both system calls and interrupts enter the kernel, but they exist for different reasons. A system call is a synchronous request initiated by software, while an interrupt is an asynchronous event generated by hardware. Confusing the two makes it harder to understand how operating systems manage privilege, devices, and execution flow.

@rhatr @Ainekk0 I wonder what the performance is like. I get 5 - 6 t/s with Qwen3.6 35B Q5 with my Ampere Altra + RTX 5070 box.

Turns out folks are talking about @Ainekk0 on Reddit! reddit.com/r/LocalLLaMA/c… But seriously -- upstreaming ggml/llama.cpp is a huge milestone for us!

Anyone have samples or a source for the Milk-V Duo Module S? Supply evaporated b/c @RadxaComputer is switching 8 to 64 GB eMMC. I hate begging on Twitter, but it would be great to find it, even the board I got months ago is impossible to find now. Pic related #escapeyourfate
