As Torvalds wrote in his book
Just for Fun,
[13] he eventually ended up writing an operating system kernel. On 25 August 1991, he (at age 21) announced this system in a
Usenet posting to the
newsgroup "comp.os.minix.":

Hello everybody out there using minix -
I'm doing a (free) operating system (just a hobby, won't be big and professional like gnu) for 386(486) AT clones. This has been brewing since april, and is starting to get ready. I'd like any feedback on things people like/dislike in minix, as my OS resembles it somewhat (same physical layout of the file-system (due to practical reasons) among other things).
I've currently ported
bash(1.08) and gcc(1.40), and things seem to work. This implies that I'll get something practical within a few months, and I'd like to know what features most people would want. Any suggestions are welcome, but I won't promise I'll implement them
Linus (
torvalds@kruuna.helsinki.fi)
PS. Yes - it's free of any minix code, and it has a multi-threaded fs. It is NOT portable (uses 386 task switching etc), and it probably never will support anything other than AT-harddisks, as that's all I have :-(.

When I got my first cubicle job in IT after college, I was all hot-to-trot on open-source stuff. I was going to change the world! Then I realized that there are only 16 hours of waking time available in a day, and only one of me, and I had 100 employees to support, and I couldn't sit there & monkey around with PFsense or FreeNAS all day trying to troubleshoot problems, which is why paying companies like Barracuda to manage the firewall nonsense started to make sense. And even troubleshooting viruses on computers...I couldn't sit there for 6 hours figuring it out, I needed to wipe the machine & get it back up & running so an employee didn't have to waste their entire day.
Although these days, everything is better. Windows 10 is pretty decent, not as good as 7 yet, but pretty good. I prefer Malwarebytes, as it does anti-virus now, plus has some really insane proactive features like EDR, and love to use Macrium for desktop & server backups, which has cryptolocker protection built-in these days. A 100TB NAS is under $10k these days. Although so many companies are going to the cloud, and DaaS, while in its infancy still, is looming.
It is crazy to see how Linux has grown. I was a really bag fan of Linux From Scratch back in the day:
I still like to monkey with those $35 Raspberry Pi boards. And today you can buy a $30 Linux smartwatch:
Expect five days of battery life and a growing list of apps to enjoy on this open-source watch.

Android launched 12 years ago, back in 2008, using a modified Linux kernel. Which is now available as a factory option in the form of Android Auto direct from vehicle manufacturers:

And Jeff Nelson wrote Google OS in 2006, which was launched as Google Chrome OS in 2009, which become what we know as Chromebooks today:

And then came full-circle, letting Chromebooks run Android apps on them using a shared kernel in protected mode:
The Play Store is coming to Chrome OS, Google announced at its I/O developer conference today -- and with that, you will soon be able to install and run

And now you can get Bluestacks, a free Android emulator, for Windows:

And of course, Microsoft had to join in with the Windows Subsystem for Linux (WSL), with WSL2 adding a real Linux kernel with full system call capabilities:

It's really fun reading computer history, especially as I was born in the early 80's & computers became a part of my childhood growing up, as we got to see all of this unfold.
I had no idea that in 2021, I'd be addicted to 1-minute videos on TikTok on a tiny color screen streaming wirelessly in the palm of my hand & preventing me from falling asleep at a reasonable hour, hahaha! Tim Berners-Lee wrote a fun book called "Weaving the Web: The Original Design and Ultimate Destiny of the World Wide Web" that's worth a read (audiobook version also available!)

Another really good book is "Where Wizards Stay Up Late: The Origins of the Internet" from 1996, which is one of the best histories of the Internet I've read:

I've posted about this before, but before she passed, I always enjoyed talking to my grandma about technology. She was born in the depression & lived to be nearly 100 years old. She was born just decades after the Wright Brother's first flight, then saw WWII, the Jet Age, men landing on the moon, Roomba's, flat-screen TV's you could hang on the wall, Facetime video calls, and Alexa reading you books & setting timers when verbally asked. We really live in a golden age of technology! Last year I picked up a 12.9" iPad Pro with the Pencil 2.0 & do everything from 2D vector artwork to 3D CAD on it. I design stuff to run on my vinyl cutter, CNC machine, laser machine, and 3D printer...all of which I own & live in my basement! You can get an AMAZING 3D printer for less than the price of a Playstation these days!
I also have an Oculus wireless VR headset (base version is $300 & comes with a built-in computer that has roughly PS3 graphics!) & can use it draw in 3D, play games, stream games wirelessly from my computer under Steam, etc. Everything is like magic these days!
