Checksums and Hamming distance 

Heh.. yeah... well... I'm playing the long game. My hope is that the vast majority of people who watch these videos have never heard of the channel yet. No need to apologize to them, right? :)

Not sure if that " ...have never heard of the channel yet..." worked a planned.

@@nikolaimikuszeit3204 lol probably not but I'm glad he's back making vids!

Yeah, I anticipate the vid on CRC, hopefully it doesn't take many months for it to come out.

@@BenEater I just found your videos on building an 8 bit computer and I am buying parts on ebay as I type, so don't sweat it.

I hate you but I love you.

@@-X3R0 I'll take that! 😁😁

Cute

It took him that long to carefully cut and place all those wires

I always knew a value was assigned to both groups of data and them the two are compared, but i've always wanted to know exactly how it works. While this video might not explain complex versions like MD5 or xxHash or stuff I use professionally, it still showed me soooo much! Plus I would NEVER understand the more complex ones anyway XD

I think the problem with this, is that we can't distinct if there are three wrong bits or just one. If we try to correct the single bit we know that is wrong, and use the message, maybe there is actually three wrong bits and the message will pass with errors in there

@@gabrielveloso1325 It's more a case of if you haven't exceeded the correctable number, then you output the corrected block, and if there are more than that you just say "uncorrectable errors found". Multidimensional parity is a distinct algorithm that builds on traditional parity checks (as do a lot of others, like Hamming Codes). For N dimensions, you can correct N/2 errors and detect N+1, so a 4D version could correct two and detect five, but it would need a lot of parity bits to do so.

Happy birthday!

Looks good to me

youtube is the new education system. better than any school out there :)

It's a shame that the education system pays/treats teachers so badly.

And always told by other teachers that they will never amount to anything whilst during their time at school.

They are the best teachers simply because they are outside the education system .

it's survivorship bias. We can't get an Albert Einstein in every little village. We define a genius as something very rare. Is all about how we define it. Every little village has a human, and every human is a genius compared to the best AI systems we currently have, assuming intelligence is on a continuum. It's all relative to what you define as common and compare against. As such you can't escape this law no matter the level you work on. And this means places like RU-vid - a system which somehow can act as a global education platform, will always condense the best teachers in this case. Your underlining assumption is that RU-vid and online learning is not the best way to do learning - that somehow the traditional way is the way to go and we should improve on that. Which is actually wrong for most subjects which we generally consider that "they belong in school". The traditional education system is already reached the local maximum - it can't get 10x-100x better no matter what you do - and that is basically a similar situation like the ICE cars vs electric cars. For the simple fact that they have less complexity, electric cars should be pushed instead - no matter of pollution or global warming or resources or anything. Just design complexity alone must be the key decision criteria in driving out ICE cars.. So similarly the shame is not that we need more resources for our universities and we don't do that or whatever im reading in this comments above. The shame is that this traditional education system is already a dead end, and is not realized as such, and all those resources and effort and everything will be wasted investment compared to just pouring that into the online space and thinking seriously how to incentivize that - how to build a real working solution for educating everybody in the world. Because RU-vid is not it. RU-vid is a placeholder since there isn't something better available. Specifically on the question of "how to build the education platform", i'm assembled a list of great teachers over years, and Ben Eater is definitely on it. But the fundamental problem of why this is happening in general is far deeper then just this education context, it's about incentives, about economy, about value systems, about understanding, about truth, about how our mind works, about how we differ from each other, about what we want and should want - because we are explicitly or implicitly programming what people want and how they live lives, etc, etc - its a highly interconnected mess and "education" can't be fixed independently. We don't understand enough about it yet. It's a rely hard problem. This is why was not solved already despite the best minds constantly thinking about it. We gonna need more time to understand it in this holistic sense because any other attempt is gonna produce more of the same crap, we gonna still leave good teachers out, and comments with many likes like yours gonna still be a thing in 50 years - acknowledging the problem - basically that's how we know we did not solve it yet :)

Watching him work with analog (?) computing like this was truly amazing for me. I'm no coder or engineer or mathematician, but I work with computers and data and video every day. Watching him just map pins and run power to make things come to life was almost as eye opening as realizing South America fits into Africa like a puzzle piece. I always knew what computers do (on a surface level) but to see them built in such a mechanical and simple way really made me see the whole picture for the first time.

Off topic but since GOT was garbage, this video was bound to be more exciting than it

@@Artaxerxes. Yeah I cheated a little bit :)
