  • Been ages since I had to recompile a Linux kernel to deal with hard real time (via RTAI) but I recall emc2 being a great alternative to all the fussing around recompiling as some one did all the work for that.

    I also recall using this resource . Eventually I just made a class for the threads I was using to wrap POSIX and RTAI calls for periodic tasks and chose which was the underlying method on a compiler flag. If I was on my desktop I could proof of concept most things in POSIX and then test on the RTAI machine. If I need to revisit this again I may dust off my old class and add freeRTOS stuff to it so I can prototype on Linux then try to squeeze it on to an esp32.


  • @folkrav is right here

    And I’ll posit that you likely wouldn’t like this ability to exist in the first place.

    Let me walk you through a thought experiment. Any system that requires a verification step is likely tied to identity and putting up a gate to get in based on the identity or using it to get a token to access it ties you to that activity. Ok great let’s not let the kids see porn, but the exact same approach can be used to prevent or put a chilling effect on people seeking lgbt content, anti Vax content, unionization information,church gatherings, crypto schemes,academic research, Israel, Palestine, or anything really.

    The internet was never intended to be a secure place it was intended to survive a devastating nuclear attack and keep information flowing. Tacking on arbitrary mortality gates is Orwellian and not how the internet was designed to function. Maybe these guys need to a seperate network (without blackjack and hookers) just for the content you want kids to see and not tell them about the internet till later because these proposed measures are like outlawing the letter q because you don’t like that it leads to the word question.










  • No it’s not paranoia if they are actually out to get you.

    If they are out to get us it’s just baffling to me. The internet was originally designed as a communications tool to survive large parts being damaged in the event of a major disaster/attack.

    It got hijacked by people first who used it to share less and scientific information and more for the lack of a better word human information. Then corporations came and wanted to extract value from it some how. So we had the Dotcom bubbles and pop-up ads.

    Now I don’t have the hindsight now to succinctly explain what happened next but then Facebook became a dominant social media platform. And everyone gave them info about themselves contrary to the previous advice about never using your real name on the internet.

    Now we have governments world wide actively trying to police porn a good 50 years after it existed on the internet. 20 years since it was freely and widely available as streaming video? What’s the goal trying to tax free porn somehow?

    I think the genie is out of the bottle at this point.




  • Yea this is a murky area, there are things that are clearly acts of engineering namely civil engineering projects bridges, factories, etc., that fit very well with the way the title of engineer is sanctioned province by province.

    It gets murky for me with transportation things, here I still believe they should be scanctioned engineers but I don’t feel the provinces are the best ones to mandate who should be a licensed engineer for something that travels at 700 kph across the country, I think that’s more a national level interest.

    Messing things further is in other countries there isn’t a special meaning to the word engineer and it’s missused in our sense of context. The title is tossed around in some places for things like sanitation engineer and software engineer, where what these folks are doing is clearly not acts of engineering but the title is given In lieu of increased pay.

    Electrical engineering is smack dab in the grey area if it was work on a big power plant sure traditional act of engineering. Designing firmware for a mass produced widget may not be. But if the job is being advertised in the US they’d both be looking for an electrical engineer. And a lazy hr person here may be looking for an EE in Canada skipping over candidates that don’t have the certificate from the provincial engineering body but can do the job as good or if not better.

    Again this confusion is avoided if everyone knows Engineer is a very loaded word and need a to be handled with care in the confines of Canada, but we as Canadians need to understand others don’t give the same care to this word.

    The PPC guy is probably playing this up to get him free publicity at this point as he should be painfully aware of this from his undergraduate courses beating it into I his skull.

    That said it’s not a bad idea to examine the details to see if updates can be made to definitions in the provincial acts so engineers can better serve the public and we can avoid policing the use unnecessarily. I also think we should have a federal level dealing with acts of engineering that normally cross provincial boarders

    Argh way to long winded owell enjoy the wall of text

    Ah I’ve gotten to the point where I have to define what “frame” and epoch each time base is in before I’ll touch the representation of time( Unix,Gregorian, etc) .To be honest I’m probably just scratching the surface of time problem.

    Hell probably the reason we haven’t seen time travellers is we suck at tracking time and you probably need to accurately know your time and place to a very good precision to travel to a given point and we can’t say where and when that is with enough accuracy to facilitate where to land. And people don’t want to land in the earth’s surface or 10000 km away from a stable orbit. Maybe some writer can build that out for a time travel book or to discount it for some reason lol
