A simple operating system kernel for educational purposes

This isn’t gonna be a random because I do eventually get to a Tech and YouTube related topic.

YouTube is actually killing itself with all of the dumbass rules they’re implementing. Trying to child proof or limit educational content is genuinely a shit policy. The reason so many gaming channels are switching to twitch because it doesn’t try to censor you.

But now I don’t know if you’ve heard but YouTube updated their guidelines and they’re no longer allowing content that teaches people about Hacking essentially (and I hate putting it like that but I can’t remember the exact words they used Hacking just summarizes it) which is fucking ridiculous like what the fuck else, are they gonna stop allowing lock picking videos?

YouTube has always been an amazing FREE resource for people learning Programming, Cyber Security, IT related fields, and even shit like lock picking, cooking, car stuff, and all that stuff. Even sometimes when the tutorials aren’t as detailed or helpful to me they might be exactly what someone else needed. And Cyber Security can be a difficult topic to learn for free. It’s not impossible far from it, but YouTube being there was always great. And to think that a lot of those could be taken down and all of the Security based channels could either lose all revenue or just be terminated is terrifying for everyone but more so them.

A lot of people and schools rely on YouTube for education and to learn from. It’s not like YouTube is the only resource and I understand they don’t want to be liable for teaching people that use these skills for malicious purposes but script kiddies and malicious people can easily get the same knowledge. Or pay someone to give them what they want. But that’s unfair to the people that don’t use the information maliciously.

It’s the same for the channels of different topics can’t even swear and it’s ridiculous there’s so many better options than just banning it. Like FUCK kids nowadays hear swearing from their older siblings, parents, friends, and TV it’s inevitable whether someone swears or not and YouTube is not our parents, they aren’t CBS, so stop child proofing the fucking site and let us learn. Fuck.

TLDR YouTube is banning educational hacking videos and are being retarded with rules in general

Been really busy with things haven’t got around to posting a book in like a week or so..

But I’ll post one today..

This book...

This book, available for free online or you can buy it, written in 1994. But so under appreciated by people for some reason most people never have seen it or know about it. But this is the ONLY book I know of that actually covers this topic.. the only book in existence that specifically goes thru how OOP can be done with C.

NOW hold up before you say just use C++ stop and think for a second.. bear with me.

First off this book is purely for informational purposes and educational use to deepen your understanding of what OOP is actually doing behind the scenes in languages like C++ where keywords exist for these things and you just blindly use them without thinking about under the hood.

This book contains a lot of code and builds you up a complexly library from scratch to make OOP in C... now I don’t take this book literally and this but I have implemented some concepts from this book in projects in the past, and it helps a lot.

Also in my honest opinion If you finish this book, you will be a better C programmer AND c++ programmer, C programming because it teaches you a lot about complex things that you never thought about doing with the language. It proves you can do polymorphism can do inheritance and encapsulation. And it’s not really bloated either.

This books is an awesome book, if you don’t understand C pointers you definitely will after this book.. if you don’t understand OOP in C++ what’s really going on.. you will after this book. After all C++ began as just a preprocessor of C.

Great book for writing reusable, extendable large scale embedded c systems.

Anyway.. rare book of which should not be rare considering it’s free.

School gave me 3 DigitalOcean droplets to try out Kubernetes in the cloud, awesome!

Wrote an Ansible script to not only simply install docker and add users but also add kubernetes, nice!

Oh wait, error?! Well I should've known this wasn't going to be easy... ah well no problem. Let's see... Ansible is cryptic as always, it can't connect to the API server? Is it even running?

Let's ssh to the master, ah nothing is running, great. Let's try out kubeadm init and see what happens, oh gosh, my Docker version has not been validated! No problem, let's just downgrade!

How do I do that? Oh I know, change the version in the role! Wait that version doesn't exit? Let's travel to Docker's website and see what versions exist of docker-ce, oh I see, it needs a subversion, no problem.

Oh that errors too? Wait then what... Oh I need a ~ and a ubuntu and a 0 somewhere, my mistake!

Let's run it again! Fails!

Same ssh process, oh wait...

Oh god no...

Kubernetes requires 2 cores and these things only have 1...

Welp, time to ask the teachers to resize my droplet by a small amount tomorrow, hopefully I'll get a new error!

----------------------------------------------

My adventure so far with Kubernetes. I'm not installing it for any serious/prod reason, just for educational purposes. K8s seems like 'endgame' to me, like one of the 'big guys' that big enterprises use so I'm eager to throw stuff at a droplet and see what happens.

Going further down the rabbit hole tomorrow!

Wish me luck :3

(And yes, I could've figured this all out beforehand with documentation, but this is more fun in my opinion)

teamLeader: We can't release because your change doesn't work, it breaks on the machine ABC123
iHateForALiving: I diagnosed the issue and I still don't know what's related to. BUT I'm 100% sure it's not related to my change, or anything that has changed in the last 24 months. Anyway we can take a look at this, just give me admin credentials for this machine.
teamLeader: no we can't.
iHateForALiving: ... Wait what? How am I supposed to reproduce the issue? Why can't I access the machine?
teamLeader: It's in use by the testers.
iHateForALiving: What for?
teamLeader: ... Educational purposes!

They report some issue on some particular machine, then refuse to give us access to said machine to reproduce the issue because they have "educational purposes", me and God know fuck kind of education I have in mind for this circus but as soon as I get my hands on them they'll get a hint.

So in my school, all classes now have a laptop. Our laptop's touchpad just suddenly stopped working on Monday, but oddly enough, only in Windows. Rebooting the laptop or shutting it down didn't help. Now, on Wednesday, it magically started working again.

Umm okay thanks for working again I guess

I am the old famous kiddy here, who just came back days before school exam starts^^

Just to say, I want to ask you all, is it ethical(?) to release a hacking/cheating creation tool for games for educational™ purposes?

I have been making a cheat creation tool called Mysterium, but I am not sure where to use it. I made cheats for some big title games, and reported them to the developers, patched, and got some in game items in return....

Long story short, is it okay to release to the public, or should i release this product to game developers?

Sincerely,
A kid who made cheats since he can't play games well and wanted to get some free items

Seeing as quite a few people here use Macs, I wonder.. How many have tried Hackintosh? Kinda curious about projects like iAtkos but don't feel like donating nor replacing my gtx 1080 for the purpose..

Not that I would want to build a "cheapskate" Mac workstation but rather for educational purposes.. :)

I've had this idea for some time now. How about a website that gathers some of the most well written open-source code and allows you to easily read it for educational purposes? Everyone says that reading source code can be a great learning tool but directly jumping into github is not very friendly to newcomers. I saw what underscore.js has done with the annotated code link and I think it's great. What do you think?

What do you do? Not your title, but your day to day.
For example:
I beat Linux systems into submission when they refuse to do what they're supposed to, and I set up services at the request of my clients like SSH and others for research, and educational purposes.

I think one of the hardest experiences as a junior is the oscillation from perceived competency to perceived incompetency.

I just spent the last 4 weeks putting together my first major UI set of components for a financial calculator. Uses Vue, Quasar, a lot of data transformation and reactive UI programming. I felt quite chuffed. Its pending merge.

Then my lead asked me to help him debug something on the flagship and legacy project; for educational purposes, not that he actually needs my help. The application is 100x the size of the one I have been working on, and monolithic. Orders of magnitude more complex.

The jump from a sense of “I might be able to do this” to “I could never do that” was almost soul destroying. Like looking back over the last ten meters you ran, realising that running is hard and you did it. Only to look ahead and realise there are easily 100 miles ahead of you.

How the fuck do you cope with that.

Gonna set up a linux server for educational purposes (VM), which distro would be fitting?

(thinking about Arch actually (have a couple of years experience with Ubuntu))

I came across this code snippet on Quora, and I tried crashing the Codeforces server (strictly for educational purposes). But this thing wouldn’t compile, either because fork() was not declared in the scope, or the file <unistd.h> was not found. I tried it on different C++ machines. What is the fix for this ?

Dors anyone know a good email bombing service?
