   Manta – A tool for FPGA Debugging and Rapid Prototyping▲86

   Hi HN! I'm Fischer, and I'm super stoked to share a project that I've been working on for a little over a year: Manta, an open-source, cross-platform, vendor-independent tool for debugging and rapid prototyping with FPGAs. This was originally my Master's Thesis at MIT, where I developed it for our course on FPGA design. We needed an alternative to vendor debugging tools, which only supported x86 machines running Windows or Linux. We were able to patch in macOS support with VMs, but as more students came bringing ARM-based devices, we needed a new tool. So I developed this. It's called Manta,…

    Ideogram 4.0 – open-weight 9.3B text-to-image model▲46

    It's our new text-to-image model: a 9.3B single-stream diffusion transformer trained entirely from scratch. We focused heavily on controllability through structured JSON prompts, with strong text rendering, spatial awareness through bounding box guidance, and color palette control. It has the best text rendering of any open-weight model we've tested so far, and the NF4 quantized checkpoint runs on a single 24GB GPU. For more technical details and examples see our blog post: https://ideogram.ai/blog/ideogram-4.0/ We will be happy to answer any questions :)
