It's a pretty long rant. Hope you didn't get bored :P

So I have this friend of mine who has learnt Python at good level (that's what he says) and is with me in all classes in college. I have worked with C, C++, C# and Java only and hated Python when it was taught (wk44).
So the following happened in the last 2 weeks:
Once he wrote a Python function in terminal just returning a hard coded string (lame right) and will show me how cool is it and that it is sooo much easier.
Whenever we do a mini project together he will force that we use Python. Even in Image processing when everyone is ready to work on Matlab, he insists that Python would be a better option.
We asked that this XYZ is very easy to implement on Matlab.
We then had to listen about the large and great community of Python and that it has Libraries for everything and that it is the greatest programming language ever.
One day he saw my C# project for DFA and NFA simulation which was the greatest project I have "completed" myself, and went like "Hmph, if I was you, I would use python and make a more "professional" code" (then went on arguing as always)
This happened today in Networking lab-
(Sockets was taught and we are expected to learn its programming aspects)
All students: Open linuxhowtos.org and start reading on socket programming
He : Opens some websites and downloads books on Networking with Python or someting
Now while I am reading the documentation of sockets and bind, he opens spider IDE, copy-paste the code in the book and start bugging ME that he is getting all these errors like literally showing me those errors and whining about all those problems.
Me: We are supposed to learn this in C. Here take a look at this link.
HE: No I'll use Python cuz it is better than your C. It has libraries for everything and is much easier.
Me: Alright whatever I am fed up, do whatever you want11 -
Long rant ahead.. so feel free to refill your cup of coffee and have a seat 🙂
It's completely useless. At least in the school I went to, the teachers were worse than useless. It's a bit of an old story that I've told quite a few times already, but I had a dispute with said teachers at some point after which I wasn't able nor willing to fully do the classes anymore.
So, just to set the stage.. le me, die-hard Linux user, and reasonably initiated in networking and security already, to the point that I really only needed half an ear to follow along with the classes, while most of the time I was just working on my own servers to pass the time instead. I noticed that the Moodle website that the school was using to do a big chunk of the course material with, wasn't TLS-secured. So whenever the class begins and everyone logs in to the Moodle website..? Yeah.. it wouldn't be hard for anyone in that class to steal everyone else's credentials, including the teacher's (as they were using the same network).
So I brought it up a few times in the first year, teacher was like "yeah yeah we'll do it at some point". Shortly before summer break I took the security teacher aside after class and mentioned it another time - please please take the opportunity to do it during summer break.
Coming back in September.. nothing happened. Maybe I needed to bring in more evidence that this is a serious issue, so I asked the security teacher: can I make a proper PoC using my machines in my home network to steal the credentials of my own Moodle account and mail a screencast to you as a private disclosure? She said "yeah sure, that's fine".
Pro tip: make the people involved sign a written contract for this!!! It'll cover your ass when they decide to be dicks.. which spoiler alert, these teachers decided they wanted to be.
So I made the PoC, mailed it to them, yada yada yada... Soon after, next class, and I noticed that my VPN server was blocked. Now I used my personal VPN server at the time mostly to access a file server at home to securely fetch documents I needed in class, without having to carry an external hard drive with me all the time. However it was also used for gateway redirection (i.e. the main purpose of commercial VPN's, le new IP for "le onenumity"). I mean for example, if some douche in that class would've decided to ARP poison the network and steal credentials, my VPN connection would've prevented that.. it was a decent workaround. But now it's for some reason causing Moodle to throw some type of 403.
Asked the teacher for routers and switches I had a class from at the time.. why is my VPN server blocked? He replied with the statement that "yeah we blocked it because you can bypass the firewall with that and watch porn in class".
Alright, fair enough. I can indeed bypass the firewall with that. But watch porn.. in class? I mean I'm a bit of an exhibitionist too, but in a fucking class!? And why right after that PoC, while I've been using that VPN connection for over a year?
Not too long after that, I prematurely left that class out of sheer frustration (I remember browsing devRant with the intent to write about it while the teacher was watching 😂), and left while looking that teacher dead in the eyes.. and never have I been that cold to someone while calling them a fucking idiot.
Shortly after I've also received an email from them in which they stated that they wanted compensation for "the disruption of good service". They actually thought that I had hacked into their servers. Security teachers, ostensibly technical people, if I may add. Never seen anyone more incompetent than those 3 motherfuckers that plotted against me to save their own asses for making such a shitty infrastructure. Regarding that mail, I not so friendly replied to them that they could settle it in court if they wanted to.. but that I already knew who would win that case. Haven't heard of them since.
So yeah. That's why I regard those expensive shitty pieces of paper as such. The only thing they prove is that someone somewhere with some unknown degree of competence confirms that you know something. I think there's far too many unknowns in there.
Nowadays I'm putting my bets on a certification from the Linux Professional Institute - a renowned and well-regarded certification body in sysadmin. Last February at FOSDEM I did half of the LPIC-1 certification exam, next year I'll do the other half. With the amount of reputation the LPI has behind it, I believe that's a far better route to go with than some random school somewhere.25 -
that moment when you have to learn Docker at work, so you convince networks teacher to do that in classes.2

just found out a vulnerability in the website of the 3rd best high school in my country.
TL;DR: they had burried in some folders a c99 shell.
i am a begginer html/sql/php guy and really was looking into learning a bit here and there about them because i really like problem solving and found out ctfs mainly focus on this part of programming. i am a c++ programmer which does school contest like programming problems and i really enjoy them.
now back on topic.
with this urge to learn more web programming i said to myself what other method to learn better than real life sites! so i did just that. i first checked my school site. right click. inspect element. it seemed the site was made with wordpress. after looking more into the html code for the site i concluded all the images and files i could see on the site were from a folder on the server named 'wp-content/uploads'. i checked the folder. and here it got interesting. i did a get request on the site. saw the details. then i checked the site. bingo! there are 3 folders named '2017', '2018', '2019'. i said to myself: 'i am god.'
i could literally see all the announcements they have made from 2017-2019. and they were organised by month!!! my curiosity to see everything got me to the final destination.
with this adrenaline i thought about another site. in my city i have the 3rd most acclaimed high school in the country. what about checking their security?
so i typed the web address. looked around. again, right click, inspect element and looked around the source code. this time i was more lucky. this site is handmade!!! i was soooo happy because with my school's site i was restricted with what they have made with wordpress and i don't have much experience with it.
amd so i began looking what request the site made for the logos and other links. it seemed all the other links on the site were with this format: www.site.com/index.php?home. and i was very confused and still am. is this referencing some part of the site in the index.php file? is the whole site written inside the index.php file and with the question mark you just get to a part of the site? i don't really get it.
so nothing interesting inside the networking tab, just some stylesheets for the site's design i guess. i switched to the debugger tab and holy moly!! yes, it had that tree structure. very familiar. just like a project inside codeblocks or something familiar with it. and then it clicked me. there was the index.php file! and there was another folder from which i've seen nothing from the network tab. i finally got a lead!! i returned in the network tab, did a request to see the spgm folder and boooom a site appeared and i saw some files and folders from 2016. there was a spgm.js file and a spgm.php file. there was a contrib, flavors, gal and lang folders. then it once again clicked me! the lang folder was las updated this year in february. so i checked the folder and there were some files named lang with the extension named after their language and these files were last updated in 2016 so i left them alone. but there was this little snitch, this little 650K file named after the name of the school's site with the extension '.php' aaaaand it was last modified this year!!!! i was so excited! i thought i found a secret and different design of the site or something completely else! i clicked it and at first i was scared there was this black/red theme going on my screen and something was a little odd. there were no school announcements or event, nononoooo. this was still a tree structured view. at the top of the site it's written '!c99Shell v. 1.0...'
this was a big nono. i saw i could acces all kinds of folders. then i switched to the normal school website and tried to access a folder i have seen named userfiles and got a 403 forbidden error. wopsie. i then switched to the c99 shell website and tried to access the userfiles folder and my boy showed all of its contents. it was nakeeed naked. like very naked. and in the userfiles folder there were all, but i mean ALL files and folders they have on the server. there were a file with the salary of each job available in the school. some announcements. there was a list with all the students which failed classes. there were folders for contests they held. it was an absolute mess and i couldn't believe it.
i stopped and looked at the monitor. what have i done? just to learn some web programming i just leaked the server of the 3rd most famous high school in my country. image a black hat which would have seriously caused more damage. currently i am writing an email to the school to updrage their security because it is reaaaaly bad.
and the journy didn't end here. i 'hacked' the site 2 days ago and just now i thought about writing an email to the school. after i found i could access the WHOLE server i searched for the real attacker so if you want to knkw how this one went let me know in the comments.
sorry for the long post, but couldn't held it anymore13 -
Ok so Swift's module system creates implicit namespace, meaning gone are the days of Objective-c frameworks / classes having prefixes.
I get that, and its a great advancement. But when I'm using 3 different social media SDK's, a networking library and some persistence cocoapods and I have to use classes called "AccessToken" and "Manager" ... come on guys, name your shit better.
I'm looking at you Facebook and AlamoFire!!! -
Theory should be minimal courses, just something to think about and not something that expands through the entire curriculum as if anyone was to use it. Theory and fundamentals are enough, after that have career paths over what students want to focus on depending on a class that takes them through each different field: web development, db development, micro controller programming, os programming networking programming etc etc etc.
Basically, not :hey! here are some shitty basic programming classes, ok now let us move into calculus 1, 2, 3 etc etc. Most people come out of schools with no knowledge of what happens in the real world.3 -
Once again the department head fucks up my degree plan!
I'm getting my associates degree in Cyber Security. So we have to take networking courses and what not. So my institution recently became a Cisco certified teaching establishment or something along the lines of that.
The department head said that everyone who was enrolled in classes before the upcoming fall semester would have to take the new Cisco networking classes and not switch to the new degree plan. (We would take 3 Cisco classes instead of the new degree plan which is 5 or 6) so we planned and register for those classes.
Now he comes back and says we don't have to take those new classes. So it just fucks up the whole shit.
Switching to the new degree plan would add like 3 semesters to my total semester count and I'm supposed to graduate. August 2018
Fuck this new shit. Even tho I need Cisco.
I plan on taking The Cisco classes after I graduate with my associates degree while I'm going to a university for a dual degree in Software Engineering and Cyber Security
