GNU Linux bash – maximum best compression for binary data – xz (LZMA) vs zstd vs 7zip (7z) vs (parallel multi threaded multi core) bzip2 – why it is better to have A LOT of swap space (RAM 3x or 4x)

once upon a time, compressing massive amounts of binary was required. hostnamectl; # tested on Operating System: Debian GNU/Linux 12 (bookworm) Kernel: Linux 6.1.0-12-amd64 Architecture: x86-64 lscpu | grep -E ‘Architecture|Model name|Thread|Core’; # tested on CPU Architecture: x86_64 Model name: […]

looking for a new SoC? (or SBC?) – while still in infant stages – Open RISC-V computing standard is the future for Google Android SmartPhones and NASA  – RISC-V SoC Lichee Pi 4A vs StarFive VisionFive V2 – battle rages on Raspberry Pi 4 vs ODROID-N2L SOB – SoC

From Open Source software to Open Hardware: RISC-V is the future: “Computer chip designs are expensive and hard to license. That’s all about to change thanks to the popular open standard known as RISC-V” future Smart Phones could be […]

AMD Ryzen 5600G + Gigabyte Aorus B550 + 2x NVMe Kingston SA2000M81000G + RAID0 (AMD RAIDXpert2) worth it? does it work with GNU Linux? 8k Youtube Benchmark passed on GNU Linux Debian 11 MATE – enable enable SVM Mode in UEFI BIOS to enable KVM Virtualization support

update: 2024-04: system running well fastest AMD with integrated GPU would be: Ryzen 7 8700G (search bundle on ebay) the Ryzen 7 has more cores, so single core wise the CPUs are close to each other, multicore the 7 should […]

Power Efficient Gaming – is this possible? YES IT IS! – Horizon Zero Dawn on AMD Ryzen 5600G (VEGA Cezanne OnBoard GPU) with as little as 86W! – GNU Linux using half the power of Windows 10 when Idle! #wtf? – enable enable SVM Mode in UEFI BIOS to enable KVM Virtualization support

Even managed to run this system ONLY with SOLAR POWER from March to November (but not winter X-D) Of course RISC(V/ARM) based (mobile) gaming systems would be those that use the least amount of power per frame 😀 But it […]

GNU Linux Debian 10/11/Ubuntu – kvm-qemu virtualization host – guest auto resize screen – disk bench Windows 7 64Bit vm guest (only 32Bit works) – “Unable to init server: Could not connect: Connection refused” – wtf esxi has no clone button

first off the praise: kvm-qemu is a high performance nicely scriptable virtualization system if it works, it can do pretty things 🙂 IN CONTRAST TO iESXI SH** WARE CLONING A VM IS A EASY AS: virt-clone –original debian12 –name debian12-clone […]

GNU Linux – basic harddisks benchmarks with dd and fio (ssds  KINGSTON SKC600512G vs Samsung SSD 850 PRO vs Samsung SSD 860 EVO vs Samsung SSD 870 EVO 1TB) – ntfs vs ext4 – how fast are virtual harddisks?
13.11.2020 update 2022: next to the good old (non-destructive if used correctly) “dd” is still the way to go for benchmarking harddisks under GNU Linux. if there is a desktop: “gnome-disk-utility“ fio as always: UNIX: KISS! KEEP IT SIMPLE!) […]

games and AI all need GPUs – first Open Source RISCV GPU – userbenchmark “internet connectivity failed” – GPU Benchmark – Tensor Flow GPU and Artificial Intelligence Deep Learning and OpenAI

apologize! games = windows, still ? (although there are 6000 steam games running on linux) the very first “Open Source GPU” is in the making: “The Libre RISC-V M-Class is a RISC-V chip that is libre-licensed to the bedrock. […]
