In September 1968 I was sat at a Teletype terminal creating print and 8-hole tape copies of an Algol program for an Eliot something computer in the room next door. A year later I was using a 80 column card device to produce Fortran code to run on a Univac batch processing machine that was a 45 minute train ride away from the office. No mention of operating systems yet. My first OS encounter was on a Ferranti computer controlling a nuclear power station - an interrupt driven system using a physically huge (wardrobe size cabinet) drum for secondary memory. That was the foundation for working with desktop Personal Computers from 1977 and following all these names like CP/M, UCSD p-system, PCOS, MS-DOS, Windows, and UNIX (several flavours). This video seemed to map my leaning curve over almost 60 years in computing - as @KangJangkrik wrote 3 hours ago an engineer's bedtime story. Thank you for this rewind.

I can relate. I started programming as a high-school sophomore in 1976. After passing the first course writing programs in BASIC on a Model 33 Teletype with paper tape storage I was the only student that year to learn FORTRAN. That involved going to the school district administrative building to use their card punch, then taking my card deck to the data center, and finally picking up the results the next day.

I think Tanenbaums definition is the best (he probably didn't come up with it, but it's what he states in one of his books.) He says that an operating system perfoms two functions. One is resource management and the other is to provide an abstraction layer. A sort of extended machine. If you use the definition most people use (erroneously in my opinion), then you'll end up having to argue that Edge is part of the Windows OS. Which is pretty ridiculous. It's just a program shipped with the OS.

The idea that Linux or Windows is just everything that comes with an install (in terms of calling them OSs) is very nebulous and reductive. I think most people use such a definition because they don't know any better and then if they ever have it pointed out to them that there is a stricter definition (I'd also say arguably more correct and useful) they don't want to accept or consider it because they didn't come across the idea on their own. Obviously that's just my opinion, but I do think it's not a very good definition. I mean if they remove Word pad from Windows, but keep everything else the same is it then a whole different version of the operating system? I wouldn't say so at all. Word Pad is just a user space program that shipps (or shipped) with Windows. Also the definition I gave is an actual definition. What would you say is the definition of an OS that most people use. Yes you know it when you see it (sort of), but can you really describe it succinctly and clearly. Where as if it's just some low level software that provides two distinct but useful functions that basically any modern system that people would refer to as an OS provides at it's core, then it's relatively easy to define. Anyway I know that was a bit of a rant 😅.

Symbian OS was born from the PDA world, focused on optimising limited hardware resources. Programming on it had a very steep learning curve, due to this optimization and the absolute difference from typical PC programming. It was very hard for any programmer not experienced with Symbian to move to it and port any of the existing software. No matter what we did to improve the tools, it was hard to program. The other issue was that Symbian was owned by companies that were competitors with eachother: no one wanted to share tools for developers (e.g. no common ask ) and they didn't want a common user interface

I loved my Nokia Symbian devices, and wonder what could have been if they were able to properly respond to the iPhone paradigm change. I didn’t follow Nokia to Windows phone, I bought my first iPhone instead. Didn’t have the same cool factor as the E7, E90, E71, N8, N95 and all that. Sometimes I think if I could get a device like the E71, same size and shape with the qwerty board, but it could hold unlimited text messages and had conversations like iOS messages that I would use and love that thing. I liked how I could unlock the phone, start typing a name, press a button and immediately send them a text. I used to do it without looking. At this point I’m just rambling.

There were plans for a phone that you could operate with your fingertips like iPhone. However the phone manufacturers didn't want to go full smartphones, believing that the "phone" part was more important than the "smart" part. :( Nokia was adamant that touch screen was a gimmick, and that people wanted the S60...

For example the most important was the suffix L for functions that could "Leave": "leave" meant that the function allocate memory and memory allocation can fail. This is a throiwback to the PDA origins and the very small amount of RAM available on typical devices. Memory management was very manual. Programming for Symbian did bring challenges similar to programming on embedded system of very old personal computers from a decade earlier. iOS and Android did bring a programming style more similar to the PC world with less contrainstraints in memory management.

When I began to study computers, in 1995, I wish ~ I SO wish, I had this video. They started to teach us about operating systems, but it was SO damn confusing. And in the middle of my course, the SCO-Linux legal debacle was playing out, being expensive, carrying the strong possibility that one party may control the rights to every working operating system, or at least, to everything that had UNIX in its parentage. Like Linux for example. Like (less directly, less obviously) the Apple desktop OS. Trying to get your head around the big picture, understand how all the parts of it fit together, and the fact they were all moving, like the logs prior to the log-jam, they're all moving downstream, bobbing around independently, bumping into each other, but could jam up at any moment ... I know I was told that DOS was basically a device driver for a floppy disk and a hard drive, and that everything else it did was just tacked on as an afterthought. When Win-95 came along, it added quite a respectable user interface, but it was still slapped over the top of DOS, which wasn't an operating system's arm-pit. I quite liked Win2k. I had been using NT4 as my daily, so ... I liked XP. In '97 or so, I discovered I could download a shareware version of VMware, and do guest operating systems. Hello RedHat. That was LONG before they floated as a company .... Linux disros became like one of those desktop toys for me, with the swinging balls. Something you poke & prod and play with. You could pass networking through, you could (the default) have the whole network stack inside the VM talk to the ISP and the Internet as an independent client ... there was a lot to play with and figure out. And IP6 is coming, which, means this IP4 and address translation and DHCP and all that shit ~ that complexity is going away. Right? That was bloody nearly 30 years ago! Did I mention log jams? Today? Linux Mint + Mate ~ very happy with my choice. If you listen to the Artificial Intelligence crowd (they’re hard to get away from) then the next development of everything, from the screensaver to the whole internet and computational landscape, is about to change. I’m pretty sure I don’t WANT a computer that has AI as any part of its operating system ~ let along the whole damn thing. I don’t know that I need a Trusted Computing Module (I don’t trust it) and I don’t know that I need a neural processing unit. That seems a bit like building a new church, by starting with a big hole, where you assemble and then cover a black mass altar, inverted cross, and then roof it over and build the nice koom-bar-ya church on top of it.

Perhaps others can jog my memory about an strange OS I worked on in the late 1960s. In 1969 the IT Manager of a large UK bank who has bought lots of IBM mainframes gave me a special assignment. The bank for some reason had bought another mainframe - maybe Univac or Boroughs. They were having implementation problems. I had to go and work at a new data centre still being constructed where the machine was installed. My job was to analyse the many memory dumps when the OS aborted and liaise with the developers in the States. What was unusual was the OS and compilers etc were all written in Algo (I think). So for example, the Algo compiler was used to compile the Algo compiler! And I think the machine used a reverse polish notation. I've never came across such a machine architecture since but thought it was innovative though it did mean there were Algo extensions to work at bit and channel level. It was challenging as I was only a COBOL programmer at the bank, though I had taught myself Fortran before I started there and had experimented with logic circuits. And quite lonely work - just me and the fax machine to the States. Plus it was located in a rough suburb of London, so quite a trek to get to. I soon left and went to work for IBM! But IBM would only confirm my appointment if the bank gave permission for me to leave! Which they did :)

From 1982 to 1984 my employer had me run an EPA simulation model for chemical partitioning in defined environments. We contracted with a company that provided timeshare on a mainframe and I learned how to use job control language. Because I could set up multiple jobs and they would run overnight, I wouldn’t know the output until the next day. It was a lot of trial and error. And because billing was once a month, it turned out, I had blown the budget. I went back to gradual school, “where you gradually learn you don’t want to go to school anymore” (John Irving). There the computer facilities included a UNIX main frame, UNIX workstations, and some Apple IIs. What a change from JCL, punch cards, and tape. Needless to say, I have a long history using computers and operating systems. Many have gone by the wayside, though one is arguably my favorite as I still use a Palm today.

You took on a daunting task… Explaining the history of operating systems in 30 minutes or less… You skimmed over all of the macOS Apple, which were critical to the development of Microsoft windows… And of course, the pantheon of PC operating systems, including AmigaOS or Apple and even basic as an operating system… and a ton of players in the mini computer market like digital equipment, corporations vax VMS Still very nicely done!

very interesting video 10/10, although I already knew most of these things. kinda weird considering im from 05. btw did you know that before Windows Mobile 5, the os stored programs and other data in ram? flash was too expensive which makes it a pain when the battery runs out because all your data is gone then unless you have a backup to restore from lol

This topic has really fascinated me lately. As well as the thought of how advanced our hardware is getting and I hope we soon see a ton of improvement in the software department. Especially in video game development. Right now game development is so insanely tedious and I hope one day we will find ways to stream line things and or make them much more intuitive.

Retired electronics eng here. There was a story that at one point when MS was trying to kill Lotus 1-2-3 that the OS team had a saying for the next version of DOS - "DOS aint done til Lotus wont run". But that was by far not the worst thing that MS did. Often they would come to companies that had software like a TCPIP stack (I worked for a company with the first commercial stack for the PC) and say we want to license it for 20 cents a copy (we got $200). They would say either accept it or we develop it and include it in the OS. This was how much of windows utilities originated - disk utilities, FAX software, TCPIP stack etc. One by one they got put under by the juggernaut of MS. It meant more for less for consumers but often it also meant an inferior product. I can remember a large airline begging with us to not stop supporting our windows TCPIP stack because the MS stack just didnt work in their environment. BTW we also had the first browser for a PC called Emissary and its logo was a blue e - sound familiar?

You should consider writing a book. There are so many out there about the broad strokes of the PC history, I’d think there’d be a enthusiastic interest in one ff stories like yours, told from the perspective of someone who lived it.

A hospital I worked at ran a patient reg/billing app called Affinity on VMS, but I seem to recall it went from a beige VMS box to a big blue server from DEC; shoot, or maybe it was Tru64…I’m not sure now. I never administered it, I hired on as an AIX admin and we moved the Affinity app over to AIX. Anyway, that thing was NEVER bounced.

I'd define OS as a foundational system that serves as a platform for (multiple) software applications. The concept of resource management in itself doesn't seem to contain the important function of an abstraction layer / common compatibility layer for developers. For example even things like Docker arguably does hardware resource management (but it wouldn't work without OSs). Hypervisors also do hardware resource management, but from what I understand we still require an OS to run applications on. Though, it sounds like early "operating systems" were more akin to virtualization layers.

Time sharing is also the basis of every visual os like windows and Mac OS. The processor is dividing it attention between the task of rendering the screen and running any program that is in the background.

4:15 Is that Ronald Reagan? This was phenomenal, Jon (did I spell your name correctly?), and how managed to cram so much in just 30min is astounding. I’m sorry so many criticized you for leaving anything out - how they expect EVERYTHING OS-related to fit in 30min is curious - but hopefully most will simply add value to your episode by adding the ‘holes’ in the comments.

I've always thought of an OS as a government that provides basic services to enable apps (companies) to provide services to users. It is interesting to watch videos of computer history and identify companies that no longer exist. I went back and watched episodes of the PBS series "Computer Chronicles" which started around the time of the beginning of the PC when I was in highschool/college. At least 90% of the companies in the show are gone.

Love the history lesson 👍 I was introduced to micros in the MS BASIC days which I would have thought would be the stepping stone to MS-DOS. Similarly I then came across AmigaOS and Acorn’s RISC OS through home and school which were far ahead of Microsoft until W95 came along 😮

The Palm Pilot was a genius device - no handrwitten recognition and all the rest. I miss an app for smartphones that do all those things the Newton promissed. Note: The Apple IIgs ran the first full color windows GUI and Gary Kildall's GEM was an excellent GUI for PC and other machines. I have GEM installed on Virtualbox to play around with it.
