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” https://www.technologyreview.com/2023/01/09/1064876/riscv-computer-chips-10-breakthough-technologies-2023/ future Smart Phones could be […]
There are not a lot of cross OS and cross CPU benchmarks and the user might know https://www.userbenchmark.com/ which is like Geekbench but only for windows geekbench.com is multi OS (not all) and multi (not all) CPU (developed by primatelabs.com […]
why? because it would be a shame to put all those intel Macs to the trash not particularly big fan of the aluminum bodies (uses loads of energy to make also not healthy to be touched daily) but they surely […]
currently testing the AMD workstation with the KINGSTON SKC3000D2048G NVMe, directly attached to one of the 2x NVMe slots (no RAID), as this NVMe drive seems to offer excellent price-to-disk-size-and-performance-value, if it is a kingston-quality drive, then there should be […]
hardware used: AMD Ryzen 5600G Gigabyte Aorus B550 Elite AX v1 (Rev 1.1) 2x NVMe Kingston SA2000M81000G those are DATACENTER capable NVMes! (at a pretty nice price!) energy meassurements: meassured wattage when PC was idle (doing nothing): GNU Linux Debian […]
Even managed to run this system off solar power in spring, summer and autumn, 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 seems […]
check this out: When will Intel & AMD release their first ARM based SoC? “Intel is working on a new SoC (system on a chip) that will compete with the ARM-based designs that have dominated the mobile market for several […]
ZFS is probably THE most controversial filesytem in the known universe: “FOSS means that effort is shared across organizations and lowers maintenance costs significantly” (src: comment by JohnFOSS on itsfoss.com) “Mathematicians have a term for this. When you rearrange the […]
because Win 10 compared to Win 7 is incredibly slow, a way to upgrade an older ASUS Mainboard was found RAM was increased from 8 GB to 32 GB it actually had an M.2 slot for the MZ-V8P500BW NVMe SSD […]
raid10 combines the speed of raid0 with the resilience of raid1. watch out: shingled hdd are not good for RAID! setup of GNU Linux mdadm software RAID10 is actually pretty straight forward: no need to do any partitioning. # tested […]
first off the praise: kvm-qemu is a high performance nicely scriptable virtualization system if it works, it can do pretty things 🙂 especially like the x11 forwarded virt-manager gui over ssh (yes it is a bit slow… but simplicity at […]

update: Starlink reduced price to 80EUR! 😀 PLUS: THE HARDWARE IS FOR FREE! (the very good hardware alone is worth ~2000USD!) Thanks Elon! 😀 Support SpaceX: mankind’s only hope to ever reach Mars! order Starlink now! Update: Amazon […]
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. a simpler one is “gnome-disk-utility” also interesting but not very simple in installation & usage (complicated! […]
“first Benchmarks of the KX-6780A. China just developed it’s own x86 CPU with the performance of a Intel Core i7 2600 (4C/8T, 1,401 points) from 2011 the eight-core CPU-Z achieves 171 points in single-core and 1,396 points in Multi-Core comparison […]
apologize! games = windows, still ? (although there are 6000 steam games running on linux) the very first “Open Source GPU” is in the making: https://www.crowdsupply.com/libre-risc-v/m-class “The Libre RISC-V M-Class is a RISC-V chip that is libre-licensed to the bedrock. […]
got the server cheap from ebay. has unfortunately only 4x 2.5″ SAS (3.5″ would be better = more storage) one SAS drive already faulty. using the native Hardware RAID10 (4x 75GByte Hitachi HGST Ultrastar C10K600 450GB (HUC106045CSS600) 2,5″ SAS2 64MB […]
Why is quantum computing important: optimization Update: Google claims to have reached quantum supremacy The tech giant unveiled its x-quantum computer chip Bristlecone in March 2018 (src: cnet) original nasa paper: https://drive.google.com/file/d/19lv8p1fB47z1pEZVlfDXhop082Lc-kdD/view book: https://deepai.org/machine-learning/researcher/eleanor-g-rieffel https://www.amazon.com/Quantum-Computing-Introduction-Engineering-Computation/dp/0262015064 Scott’s Supreme Quantum Supremacy FAQ!

update: with more or less CPU usage this device uses like 6kWh per day (rough estimate over 30 day measurement) it runs pretty quiet even on 100% CPU load 😊👍🏻🖖🏻🍻 got it cheap on eBay and wanted to take it […]
this is a very very basic sequential harddisk write test performed on host and guest. there are multiple ways, how you could improve the performance: Use fixed size disks Allocate RAM and CPUs wisely Install the Guest Additions enable host […]
htop is really a cool tool that also lets you show per-process io disk read write usage. (what process is writing / reading how much bytes right now) start htop and hit F2 to get into setup screen. from columns […]
want to buy one? check on ebay for “sun” and “sparc” recipe: what you will need: a T1000 alternatively: ear sealing headphones + music. a LAN switch with DHCP-server/router attached LAN cables (atleast 4x (1x DHCP-server, 1x workstation/client, 1x server […]
You might want to checkout very basic sequential write/read benchmark with dd. You might also want to checkout: cross os harddisk benchmark iozone and java. ============ OS and Kernel Linux server4.localdomain 4.15.7 #1 SMP Sun Mar 4 16:43:40 CET 2018 […]
You might want to checkout very basic sequential write/read benchmark with dd. You might want to checkout iozone in c harddisk benchmark. this benchmark is especially useful if you need to measure how java is performing on your harddisk/filesystem/os (linux […]

if you want to find out what chipset / mainboard your PC / Laptop / Notebook is using and other details about the hardware. unfortunately this is not a straight forward task… and works better / worse depending on the […]
update: while this benchmark is still valid, very simple, very cross platform, with a focus on the team cpu (why is there no multi core md5? (putting many many core arm servers at disadvantage) + harddisk (two very important components) […]
