Started 25Aug2015, edited 21Aug2016 This page is in group Technology and is about a facet of multi-threaded concurrent programming where some seem to think that synchronous non-buffered channels and processes are incompatible with hard real-time systems and guaranteed deadlines. Over a beer the other night, but oh so serious, I heard a computer scientist challenge C. Liu and J. Layland’s […]
Started 14Oct2024. Updated 16Nov2024 (Movie. New unit added, with a knocking solenoid. DAY/NIGHT push button added). This page is in group My Beep-BRRR pages. It also is a follow-up from My missing smart home connection. Observe my Standard disclaimer. Intro 1 (English) I have developed a device that I call Beep-BRRR because it listens for «Beep» […]
New 29Apr2024. Updated 07Nov2024 (New style of References. [8] and those below in the list++. In work. This page is in group Technology I guess it’s a post where I try to understand its process/task model, and end up being somewhat sceptical of any potential usage on my behalf. Three rusts «Rust has been said […]
Started 21Feb2024. Updated 01Sep2024 (ForeC). This note is in group Technology. Observe Standard disclaimer. Intro: ..should not have been here These aside digressions are here because I don’t know where else to put them. They are all worthy of their own blog notes. But since their contents is not my speciality I won’t pretend. I have […]
Started 25Oct2023, updated 30Oct2023. This will be is in group Technology if I think it would be might be worth it. At first I will try to list up relevant other blog notes or lectures I have done or presented over the years, those may have filled in the same points that I initially thought […]
New 02Aug2023. Updated 30Oct2024 (Til salgs). This note is about some individual scope channel devices which send their curves to a mobile app. This app runs on several platforms. «My Pokit scopes» as in plural, is this correct? Or should it be called «My Pokit scope»? So I changed it to «My Pokit scope(s)». Observe […]
New 19Dec2022, updated 27Sep2023 (readability, I didn’t understand my own phrases, [2], [1], ChatGPT). In work. Read first but I suggest, don’t press the links. On any second read, you’re allowed to press the links. This note is my first reaction to the surprising and bold switch by XMOS, to let the xcore architecture run […]
Part of group NOTES FROM THE VAULT. Theme from 1988, moved here 12Apr2022. Updated: 09Aug2024. Finished Intro This note, in a wider context, is about how I learned about the need for a task concept, and «below» tasks, about an early but necessary runtime system of mine. The thing that started this text was that I already […]
For some years I was invited to present guest lectures in real-time programming at NTNU (Norwegian University of Science and Technology). You can read them at Publications (mirror). Those years NTNU required me to have an «affiliated» web page. Since I have not done any guest lecture since 2019, these pages therefore went dead in Oct2021 (but […]
← → Started 13May2021. Updated «after that». This note is in group Technology and My XMOS pages. It is about the XMOS tools paradigm shift with C and lib_xcore. C plus lib_xcore = xC Of course the below info makes me sad! For myself: I have enjoyed xC so much! But I am afraid, XMOS probably have […]
