I've known about logic gates and the way they work (their "rules") for a long time, but never found a video series explaining how they're applied in practice that was so easy to absorb and so well organized. Keep making more episodes plz :)

As someone who has worked with mainframe tech produced in the 1960's and well used to a format loop on a printer you soon get to learn that everything is an evolution from something before it and thus long term you just see it as X with Y. The thing is that most people today would run a mile having to do what we used to have to do, bringing in paper to the print room by 3-4 boxes which was 190+ pounds in weight. Oh the stories of the good old days where throwing a write protect ring could down an entire place if it hit the emergency power off.

Windows 10 still crashes constantly and when you least expect it. One of the reasons I now use Linux and MacOS (a Unix derivative itself). Windows 7 I did find visually appealing and was more stable than previous iterations, but nevertheless using Windows is as annoying as ever. Whenever you install a program, you always run the risk it will alter the OS so the next time you boot up, you get some error message. Oh, and it's especially vulnerable to viruses. Only recently did Microsoft provide basic antivirus as standard along with the OS. Embarrassing. Windows Vista and Windows 8 were prime example of half-baked underdeveloped versions of Windows that should have never been released.

No, Unix was terrible compared to many of its contemporaries as far as features & productivity go. It just happened to run on cheap hardware. Perfect for universities and government run organization, where securing funding for equipment is much harder than securing funding for employee man hours, even if the latter ends up costing more in the long run.

Stallman is a excellent example of taking a good idea way to far. Stallman says you should only use software that is 100% open. So for example he will not listen to mp3's (mp3 is not a open format). he thinks both ios and android are bad and should not be used. He is absolutely militant about this sort of thing. Going so far as to say that you using Skype is morally wrong because by doing so you are pressuring others to use it to talk with you, and this strips them of their freedom. He is huge in software development and open source, but people have a tendency to over look the radical honestly nonsensical parts of his dogma. The TL;DR is ya he did a lot of important stuff, but he is not some infallible savor figure.

I think she should have mentioned that UNIX is still with us in the form of Linux and Android, it really makes you appreciate the age and amount of work that went into these things. (also BSD and Darwin :) ) To me its astonishing how even after all these years, even if the way we do computing has changed completely, Linux is still very much a multi-user system designed for main frames; you can see it everywhere from user management and the permission system, to the way tasks are handled, the filesystem and the presence of TTYs. The core principles of UNIX are still very much present. Personally i find amazing how stratified, complex and messy Linux is: it never really changed from that original design, it only grew is size and functionality: you can pick up a UNIX manual from the 1980s and find that 90% of the information in there still works with some very minor changes, it blows my mind :D

The printer at 5:43 displays a carriage tape. It did control form feed, top of form and feed to a predefined position (channel). Oh, those days. I wrote a printer driver in assembler to a really no-brain printer. It had no buffer, so I had to time each character calculating the time needed to change position and feed paper. As a bonus I added a tabulator function. The printer was a desktop model. It weighed 50 kg or more. My bicycle broke down when I moved this thing home on it.
