    I like to think of cache as an ability similar to being able to borrow several books at once from the library: For a fast reader, this means being able to read more books without having to take the bus to go to the library again. The reader may not be able or interested in reading all the books they end up borrowing, but overall, it still increases quite a bit their ability to read more books in a shorter period of time.

    By the way: Branch prediction is also the cause of the current major security problem. Because what if the conditional jump is the condition that checks for if the program has the right to access some memory? (By the way: in my student accommodation we have a dryer that can dry completely in about 40mins)

      The hexspeak "Magic Debug Values" are also pretty funny, eg. the C00010FF value is used to indicate an iOS app that was killed because of a thermal event.

    Q: What did the data say to the CPU when the cache got full?
    A: "Cache me ousside how bow dah!"
    Q: What did the paraplegic program with a stutter say to the CPU pipeline?
    A: "Help I've been parallelized!"
    Q: Why was the dependent instruction executed in front of the others?
    A: For protesting the pipeline and causing delays!
    Q: Why did the instructions eventually rise up against the CPU?
    A: They were being executed based on speculation.
    Q: What is the most famous speech ever given by a cache after being cleared?
    A: "4 cores and 7 clears ago..."
    Q: Why were the corny CPU jokes banned from UA-cam?
    A: Too many FLOPS!

    This video made me sad. 10 years ago i spent 2 years in an ICT highschool course, but this playlist up to this point has thought me more already. The only thing i remember learning there was that you could power off a pc quicker by just pulling out the plug, followed by the students explaining to the teacher what bad sectors are.
    Those years killed nearly all my enthusiasm for ICT, as did my internships in refurbishment companies.(although they were fun) At this point through this playlist i notice that things aren't so obvious anymore and i have to rewind here and there to fully grasps the concepts, and i realized... this stuff is still really exciting!

    if your DRYER takes 90 mins, you must have a BLOCKAGE IN YOUR VENTING to the outside. the pipes often fill with lint and blocks airflow. if left unchecked, it could cause a FIRE. there are cleaning tools for this or you could take the vent tubes apart and clean them by hand. btw. this series is awesome!

    Irony. Carrie Ann talks about "speculative execution", which (for those watching in 2018 and are unaware of the malware's MO) is what Meltdown and Specter exploited.
    That's the reason why you never say any tech/science thing is impossible. You never know what people might figure out.

      Well to start with, there's still a pretty hefty gender gap that is probably holding this particular series back a decent amount. A lot of girls and women simply aren't interested in Computer Science compared to the number of guys that are, and I doubt there is nearly as significant of a gender disparity regarding mythology.

      I do understand you, personallym Computer Science and World History are my favorites
      But being honest, CS might be a little more complicated to understand, and that's probably why Mythology is a bit more popular

    • @magical11
      @magical11 7 років тому +13

      That's like saying: History = real answers that are mostly true; Computer science = real answers that are mostly boring!
      Mythologies are easier/more popular because they are retold as stories. They have a narrative and a human connection that's been repeated over millennia. Compared to computer science, which usually is impossible to relate to the human experience, mythology is far easier to digest and enjoy.

      This means it just has poor optimization.
      You could set up a game that runs on path tracer and all you will get is a a blurry, noisy mess every 1/60 or 1/30 of a second

    Real talk on the dryer thing: Usually long dry times actually come from your ventilation out of the back of the dryer to the outside. That hose and the pipe between the hose connection and the side of the building get clogged with lint and the occasional wasp nest. Cleaning those out will shave tons of time off your dryer and save your money on your electric bill.

    It was only a matter of time till we got a "But will it run Crysis?" joke.
    I gave a solid guffaw. Well played.

    I mean, the supercomputer feels like the most amazing thing ever, but when IBM used to fill an entire room with vacuum tubes, it probably felt like the most incredible thing ever.

    There's one thing I really couldn't get my head around when I was a student. How in the heck do they manage to attain GHz frequencies with a oscillators limited to a couple dozen megahertz? PLL's are such a genius invention

    Overall 7/10 :-) I really think this series can have impact on different age groups, and not only people with tech background or motivation. And that would be great!
    But I also have some critics, hope a useful feedback:
    *A. Host is talking far too fast.*
    *B. Not all technical facts are correct.*
    Example - The reason for few MB of cache is not the SIZE of the DIE. Is the COST of the SRAM, i.e the cost of CACHE memory. Back in time, when we speak of KB, again COST was the biggest obstacle and first factor regarding CACHE Size. Manufacturing process changed, so die size could've been scaled, but it was not reasonable to do so. Already having the SRAM cost to the roof, leaves nothing for other expenses in the pursue of bigger Cache size and perf boost. So the barrier was and still is COST of SRAM. Nowadays you have CPU & GPU on the same DIE, so the die size is not the main factor today, was not a factor back then. Hope that's clear. I think this is one of the straightforward examples of wrong information.
    Hope this feedback will be taken into consideration, because these series have good potential. For fluent or advancement speaker sure it's no problem the pace of the presenter, it's rather engaging. But for the bigger audience of non-native speakers... most definitely a big loss of audience. And probably that same audience, group of people, will not even going to try to see another video from the series. That would be a loss for the series in my opinion. As well and for those people came to seek information or just watch a cool informative video , which to be honest is even more of a reason to reconsider the pace.
    KUDOS for the effort and outcome. The video is way above average videos on youtube regarding tech, but has big room for improvements too ;-)

    I had a uni professor that used hundreds of paralellized ps3 to do encryption work... as a publicly founded research. When they stopped it, he gave away the consoles to students, and this caused ENTIRE classes to get empty because people were getting in line to fetch some. He's an absolute legend.

    Haha! I LOL when you mentioned whether or not the Sunway computer could run Crysis at max settings - cracked me up! ha! My PC back in those days (2007/2008) suffered horrendously when trying to play it on max settings, especially at the intro cut scene when the aeroplane came into the camera view flying over the clouds. My ATI Radeon HD 4650 graphics card really suffered..hehe. Ahhh the good times. :)
