Running Quartus + Questa on Apple Silicon

The current methods to run an Intel FPGA workflow on Apple Silicon involve two possibile approaches:

Using a WoA Virtual Machine: Performance is terrible (already in amd64 Windows platforms is terrible, adding two virtualization layers on top of it leads to eternal compilation times) + space wasted for all the Microsoft bloatware
Using a Docker Container: Performance is better than WoA, but the USB drivers are not working

Running Linux on UTM with Rosetta enabled should tackle these problems

Disclaimer for Baremetal installation

This guide could possibly work also when installing Debian directly on the Mac with Asahi Linux, but it is not recommended for beginners: with the standard installation procedure the Linux Kernel uses a default page size of 16K, and the rosetta binary is not designed to run with this page size. By recompiling the Linux Kernel to use 4K page sizes it should work flawlessly, but expect slower perfomance and/or higher power usage

Svelte5: A Less Favorable Vue3

Background

Svelte5 was released in October last year, touted as the best version of Svelte to date. The team was particularly proud of "runes," a reactive state system built on proxies. However, after experiencing Vue3's Composition API and SolidJS signals, I didn't feel particularly excited. This blog outlines specific issues encountered when using Svelte5 in real projects. If you're a Svelte5 enthusiast, you might want to stop reading now.

Runes Only Work in Svelte Components or .svelte.ts Files

When trying to write hooks with runes similar to React/Vue, like useCounter:


	// Using this code, we can retrieve an image from a user's filesystem, resize the image, and then upload the image
	// to a server using AJAX. Because we use base64 encoding, we can just include the image data as just another string value
	// in a JSON payload.

	// So we can use AJAX to send the file to a server, which is convenient.

	// We have one line of relevant html
	// get file in the first place => <input type="file" custom-on-change="onAcqImageFileChange" class="form-control">
