I love this presentation! There is such a fast progression in technology, yet there is so much knowledge to absorb from the past. I'm curious about the book that you hold up at the beginning of the video, do you have an ISBN number?
What an amazing video!!! I think everyone on earth should be required to watch this and learn it. I've been working with electronics for about 15 years. I love it so much for many reasons. The most important of which, is that I always learn something new. No matter how much you think you know, something comes along to show you that you don't know as much as you thought you did. Lol. Superb demonstration sir!
I'll definitely be having a look at KiCanvas. What a brilliant idea. I wonder why the code to handle decidegrees still exists and hasn't been removed in more a recent version.
The quote at the end of Sam's talk has stuck with me, the one about experience.... is only a bookmark in my memory, but all the things he says included with this quote has inspired me and encouraged me to let my curiosity sort of be the compass to get past all the unfinished and finished projects, that helps in a subtle way to choose amongst the seemingly blind and really scary paths forward....99 percent of the people that have ever been involved in life almost always run away from doing tough things, saying things like, "Why in the world would you want to do that?!''' It makes for a lonely world for me....because of a tendency to be curious about computers, TVs, but it's christmas everyday when there's something to take apart, or try to repair, or go into a deep dive down the rabbit hole into a kind of pure thinking kind of mode....it's not a lot of christmas to get into that mode, only super neat if you can get over those few hurdles to get there. Just wanted to say thanks, Sam, for your positive impact.
Glad to see all those baldish headbacks instead. Very interesting and encouraging to start listening to the Deep Space instead of such poorly recorded talks.
Many years ago I maintained a system that had a PDP-8i. I remember toggling in the RIM loader. One thing I recall from the programmers reference was they actually recommended using self modifying code! 😮 That was normally considered taboo! Back in those days I also worked on some PDP-11s & VAX 11/780s, Data General Nova & Eclipse, Collins 8500 and some Prime computers. My own computer was an IMSAI 8080, which also had a front panel.
As mentioned there are trade-offs one has to make. When the set of flags was mentioned I immediately recognized there was no mention of a negative flag. It would have been possible to use the middle four bits of opcode 0 to have several pages of 16 instructions so some useful ones could be added but, as was pointed out, it would add to the complexity of the CPU design and cost.
Looks like another one of those “good enough for soldering” microscopes that don’t quite cut it for things like silicon inspection 🧐 Still might be the right tool for the job 😊
hi everyone am trying to transmit 16QAM in gnuradio using fmcomms2 i have used random_source->constellation_encoder->interpolating_FIR_filter->fmcomms2 but it shows error Traceback (most recent call last): File "C:\Users\Dell\Documents\qpsk.py", line 369, in <module> main() File "C:\Users\Dell\Documents\qpsk.py", line 347, in main tb = top_block_cls() ^^^^^^^^^^^^^^^ File "C:\Users\Dell\Documents\qpsk.py", line 202, in __init__ self.iio_fmcomms2_source_0 = iio.fmcomms2_source_fc32('local:', [True, True, False, False], 32768) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ RuntimeError: Unable to create context
Nice video, one comment - the code in the example at 42 minutes is in error. Due to the lack of ret after the mov rax, 0x02 it will run onto the mov rax, 0x01. I e. No matter if the result of the comparison is true or false you will still end up with 0x01 in rax.
