    Yes, certainly. I will add that very soon. It is also possible to download and try yourself without paying (there is a free trial period).

    I have been building an agentic code IDE (like everybody else :)). https://syntverk.com Native cross platform app coded in rust + tauri. I prefer using it to the other agentic code…

    It is not related to OpenSparc. LEON is a SPARCv8 developed initially by ESA and later by swedish company Gaisler Research.

    Automotive Grade Linux is pretty much a Linux distribution for infotainment units. It's not about running Linux on ECUs.

    I have read this post many times and just want to say that I really like it :-). Sounds like great fun. Unfortunately not a citizen though!

    You can only address one row/column at a time in a normal DDR memory. Start by reading this if you want to learn more: https://people.freebsd.org/~lstewart/articles/cpumemory.pdf I…

    Well, on e.g. x86 you have "rep stos" instruction which pretty much amounts to memset in HW. The operation needs to be blocking otherwise you could of course do it without CPU at a…

    I am yet to see a embedded system using Qt that is not upgradeable. And lots of embedded systems are sold to consumers. In what way was I "completely wrong"? It seems to me you wer…

    Comment #19858502

    I think I'm clearly stating my assumptions. GPL3 and LGPL3 requires you to enable the user to replace the GPL/LGPL3 code on your device with the users own version of said code. It …

    Comment #19858041

    You don't agree that you need to provide a way for your customers to replace the Qt libraries? (because that is a fact of LGPL3, read the anti tivoization clause). Do you see any p…

    No need for the tone. That is really easy as you say. What you seem to have overlooked are the implications of doing this. You are forced to help customers replace the Qt libraries…

    Comment #19857595

    Your last sentence is a bit hard to comprehend but not paying for Qt and shipping a commercial embedded product is pretty difficult due to the anti-tivoization clauses of GPL3. I a…

    Comment #18607640

    Ok I'll admit I'm not familiar with medical certification. I know that the so called Qt Safe Renderer for ISO26262 compliance is a bit of a joke at least. I have seen two very big …

    Most embedded tooling is free nowadays. Free software has eaten the world and will continue to do so. I will use a free UI toolkit when I can. Qt will kill itself with their curren…

    Comment #18605917

    Reasonable? It's about $500 / month / developer with additional royalties if you are shipping devices with Qt firmware. Sure I think Qt/QML is the best UI toolkit available but thi…

    If cell providers advertises their services as "Always 100 Mbps guaranteed" that would be a problem, but do they really? Because that is not how wireless communication works. E.g. …

    Sure, I agree that you should limit ASIL certified software as much as possible. Nothing running on Linux will be certified ever. That also limits the benefits of Qt Safe Renderer.…

    This does not really mean Qt (and/or QML) is certified. It means there is support in QtCreator for exporting certain graphics (tell tales) so that they can be rendered by Qt Safe R…

    You’re confusing film and video. Anyway (D)SLR use phase detect autofocus in which you don’t have to figure out much at all. Mirrorless is another thing.
