Evropa chce vlastní platební systém nezávislý na Visa a Mastercard. Wero už funguje a má desítky milionů uživatelů. Digitální euro je ambicióznější, ale naráží na technické problémy a přílišnou složitost.

Na funkce pro výpočet transformací 1D signálů dnes navážeme. Ukážeme si zpracování 2D signálů, konkrétně rastrových obrázků. Budeme počítat rychlou dopřednou i zpětnou FFT, DCT i DST a odstraníme šum z obrázku.

Last month we showcased GreenBoost as an open-source means of augmenting NVIDIA GPU vRAM with system RAM and NVMe storage. This memory tiering solution for NVIDIA GPUs was developed by an open-source developer with a focus on CUDA and allowing larger LLMs to be handled on graphics cards with smaller vRAM capacities. There was a setback to the project due to NVIDIA legal but now the project is going in new form and also has introduced GreenBoost-Proton for helping Linux gaming on NVIDIA hardware...

The Spack package manager is quite popular in the HPC / supercomputer space for scientific software. Even with the more selective niche than a typical general purpose OS package manager, large language models (LLMs) have already proven capable of being useful in generating new Spack packages. But there have also been some headaches involved too for Spack developers...

Last year NVIDIA announced the new CUDA Tile programming model as one of the biggest updates ever to the CUDA platform. CUDA Tile brings a virtual ISA for tile-based parallel programming and they subsequently open-sourced the CUDA Tile IR as an intermediate representation built atop LLVM's MLIR. Now they are looking to hire additional LLVM compiler engineers to help foster their CUDA Tile initiatives...

In advance of the Linux 7.1 merge window opening, Miguel Ojeda sent out all of the Rust feature updates on Friday.
