New Oct2015, updated 15May2021. This note is in groups Technology and My Go (golang) notes. I think it’s fair to copy my own comments at Go Forum in this note. I would also do newer golang-nuts and golang-dev matters that I have taken part in. The latter forums I won’t backlog. You will have to go there to read […]
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 18Feb2015, updated 27Oct2021 (MIPI) – Plus a short update 31May2023 («NumPages» for .xe file for 14.4.1) This page is in group Technology (plus My XMOS pages) and is a blog note about my experience with the XMOS toolset xTIMEcomposer and XMOS HW and how I am going to use used the startKIT to control a small 40 litre […]
Started 8Sept2014, updated 9Sep2020 (User forums). This page is in group Technology and is about a facet of multi-threaded (or perhaps single-threaded) programming After having heard so often that «blocking is evil» and that it’s kind of the opposite – a necessary side of life – I have finally unblocked on the semantics. It’s both. And neither. If so, I’d have […]
This page is in group Technology. Started work on this 1Feb2014, probably finished now (updated 7Jul2020 (table)) Intro In this note I will describe two articles about software components. The article «Component Models for Reasoning» (Seceleanu, Crnkovic) [01] and «Tool support for the rapid composition, analysis and implementation of reactive services» (Kraemer, Slåtten, Herrmann) [02]. […]
New 4Dec2013, ready 08:09:10 11.12.13 (updated 15Mar2014) This page is in group Technology. Intro My starting point with this note was my surprise of the JavaScript «concurrency model» [01] – as described in HTLM5 [02] («WebAppAPIs»). I asked myself whether this «single-threaded» model had been influenced by the Model-View-Controller (MVC) [03]. Maybe, in any case […]
New: 10Nov2013, updated 22Feb2024 (Some moved to 254:[] typos, plus added some). This page is in group Technology. This note on the Internet Archive‘s Wayback Machine: A reactive manifest Disclaimer Whether this note manifests itself as a manifest, remains to be manifested. Background I will in this blog try to critically analyse The Reactive Manifesto [1]. The […]
Started 12Sep2013, finished 19Sep2013. Updated 28Jan2014 This page is in group Technology. Intro In this blog page I will try to understand how so-called «single threaded» software architectures based on «event-loop concurrency» and callbacks (where mostly all blocking is «evil»), differs from light-weight processes that communicate using channels (where any needed non-blocking is built explicitly (or by […]
1Sep2013 – updated 19Feb2015 This page is in group Technology. This is a small contribution for software programmers who do concurrent programming. It is a naïve follow-up from a previous blog note: Pike & Sutter: Concurrency vs. Concurrency, meant to install a gut feeling of when blocking is not evil. Looking back I have discovered some milestones […]
New: 25July2013, updated 29Apr2024 This page is in groups Technology and My Go (golang) notes. Updates An aside on async/await 28Apr2024. Rob Pike, at GopherConAU 2023 gave a lecture called «What We Got Right, What We Got Wrong» (here). He talks about Go concurrency at 11.30. My point here is his aside on the increasingly popular async/await paradigm. […]
