The need of an flexible app to evaluate algorithms with high performance The base app was made in a few hours, after that has it been extended and improved, It s built with Python, using Streamlit for UI, selected QuestDB for high performance database, uses stock data from Alpaca, Polygon and NewsAPI, able to run locally Continue reading Creation of a SaaS prototype stock analytics app with AI as…

It s easier than one think I ve run into problems when loading performance data into Grafana with another database used to collect statistics for huge amounts of k6 performance test data with high cardinality, after a while, normally a few months, will the update of the Grafana dashboard become slow and take longer as time pass. Continue reading K6 with QuestDB
The PDP-11 graphics capable workstation of the time was a great machine in many ways An emulator was written using SIMH PDP-11 code with added X11, original page: http://xhomer.isani.org/xhomer/ I ve ported earlier to OpenVMS (VAX/Alpha) and other newer OS es and decided to do a quick port MacOS on Apple Silicon (M1) Startup Screen Startup completed Continue reading XHomer on MacOS
Part 1 I was interested in exploring the RISC-V architecture and what possible use I could make of it. Did a little research and when it looked like the FPGA path could be the best option for me, I collected available RISC-V FPGA cores data, few would fit one on the FPGA s I have, then Continue reading Deep Dive into RISC-V on FPGA
It s time to unCloud and even unOS, real Bare Metal is trending! Implementing a legacy hardware emulator/simulator on Xilinx Zynq-7000 (xc7z010) SoC ARM/FPGA using HDL to build the HAL in the FPGA PL (Programming Logic) of the SoC while the emulator/simulator code runs in PS (Processing System) ARM core. Makes it not only quick and Continue reading Bare Metal legacy system emulator/simulator on…
If you still need to use legacy hardware as VAX, Alpha, SPARC, HP-PA or SGI you can extend their lifetime by replacing fans, power supply and also storage like SCSI disks with SD Micro. In many cases for development or non production systems it is not always justified and useful to use an expensive and/or Continue reading Renew your legacy Hardware
Porting old X11 software to the Mac Compiling using the Xcode Command Line Tools and a few code adjustments make it pass All but the sound is working A OpenVMS port is on the way Originally done by Bill Kendrick of New Breed Software
How to reset root password on VMware 6 without reinstall VMware I used this solution: Make sure VMware disk is connected and available Used Kali Linux Live Boot USB Located and mounted available partitions until I found the one with the packages on it. Located the state.tgz # cp [location]/state.tgz /temp # tar -xf state.tgz Continue reading Reset VMware 6 root password
