The stupid stories of how I was able to break my schools network just to get better internet, as well as more ridiculous fun. XD
1st year:
It was my freshman year in college. The internet sucked really, really, really badly! Too many people were clearly using it. I had to find another way to remedy this. Upon some further research through Google I found out that one can in fact turn their computer into a router. Now what’s interesting about this network is that it only works with computers by downloading the necessary software that this network provides for you. Some weird software that actually looks through your computer and makes sure it’s ok to be added to the network. Unfortunately, routers can’t download and install that software, thus no internet… but a PC that can be changed into a router itself is a different story. I found that I can download the software check the PC and then turn on my Router feature. Viola, personal fast internet connected directly into the wall. No more sharing a single shitty router!
2nd year:
This was about the year when bitcoin mining was becoming a thing, and everyone was in on it. My shitty computer couldn’t possibly pull off mining for bitcoins. I needed something faster. How I found out that I could use my schools servers was merely an accident.
I had been installing the software on every possible PC I owned, but alas all my PC’s were just not fast enough. I decided to try it on the RDS server. It worked; the command window was pumping out coins! What I came to find out was that the RDS server had 36 cores. This thing was a beast! And it made sense that it could actually pull off mining for bitcoins. A couple nights later I signed in remotely to the RDS server. I created a macro that would continuously move my mouse around in the Remote desktop screen to keep my session alive at all times, and then I’d start my bitcoin mining operation. The following morning I wake up and my session was gone. How sad I thought. I quickly try to remote back in to see what I had collected. “Error, could not connect”. Weird… this usually never happens, maybe I did the remoting wrong. I went to my schools website to do some research on my remoting problem. It was down. In fact, everything was down… I come to find out that I had accidentally shut down the schools network because of my mining operation. I wasn’t found out, but I haven’t done any mining since then.
3rd year:
As an engineering student I found out that all engineering students get access to the school’s VPN. Cool, it is technically used to get around some wonky issues with remoting into the RDS servers. What I come to find out, after messing around with it frequently, is that I can actually use the VPN against the screwed up security on the network. Remember, how I told you that a program has to be downloaded and then one can be accepted into the network? Well, I was able to bypass all of that, simply by using the school’s VPN against itself… How dense does one have to be to not have patched that one?
4th year:
It was another programming day, and I needed access to my phones memory. Using some specially made apps I could easily connect to my phone from my computer and continue my work. But what I found out was that I could in fact travel around in the network. I discovered that I can, in fact, access my phone through the network from anywhere. What resulted was the discovery that the network scales the entirety of the school. I discovered that if I left my phone down in the engineering building and then went north to the biology building, I could still continue to access it. This seems like a very fatal flaw. My idea is to hook up a webcam to a robot and remotely controlling it from the RDS servers and having this little robot go to my classes for me.
What crazy shit have you done at your University?9 -
Android flow I’ve found(fixed in android 8, working on 7.1.1):
To make app uninstallable by the normal user make the app device administrator, add “android.permission.SYSTEM_ALERT_WINDOW” to the manifest and make sure it’s not granted by the user.
Now when you try to uninstall the app, it tells you to disable it from device administrators but the device administrator disable dialog is System Window handled by the app itself and if the app has this permission but not granted, settings will crash with SecurityException leaving the app untouched.4 -
It was around for a while but I didn’t realize it was it for a long time. I was fixing computers for cash and spending in on booze while in primary school. Making websites for cash and for fun while in high school. Some guys wanted to buy my databases at the time and sending me emails that my websites rocks. I didn’t cared cause I party a lot and I didn’t need money.
Sex drugs and rock and roll was my life not a fucking computer.
Since I never had problems with math I passed exams and got myself to university and dropped out cause of those 3 funny things above. Turned out to pass exams after second year when math and physics disappeared you need to study more then 1 day before exam and party was more important for me.
I failed tremendously. My girlfriend left me I was out of money I got back to my hometown with my laptop and I somehow between depression, drugs, alcohol and killing myself reminded I was getting money from websites and I can try to follow that movie.
At that time I didn’t read single book in english in my life. I know some basic english so I decided to try to read some actionscript2 pdf. Why actionscript ? I liked those simple games. Those were fun and there was nothing better. I was reading first book at least 10 times with vocabulary that took about a month until I remembered whole book and second book was faster like 1 week third was 1 day and from then thing moved a little faster. I discovered flex just before adobe acquired macromedia and started writing in it. Started answering to some questions on forum and build some portfolio website with fancy 3d animations and stuff and finally applied for 2 jobs.
They both were amazed by my website and one of them sent me some task to do and I did it overnight and sent them back. They wanted to hire me and I need to respond to them.
Second job they invited me for talking and asking about math, if I’m ok with 3d and stuff and they offered me job closer to my home town so I picked them. The code was amazing, 3d equations, quaternions, complicated stuff bit very well written by some company that dropped project before launch and my first task was add some small feature.
I remember first day in elevator with my former boss who told me to not to get scary and take it slowly I was trying to do my task as fast as I can worried I will be fired if I don’t do it and nobody else will hire me and I won’t manage to recover from second failure. It was even more fighting with myself that I will fail again then with this task lol.
I’ve done the feature third day and when they said it’s cool and I can commit my changes it appeared to me that It might be this shit that will get me out of trouble.
I was never again wrong about programming and so wrong about trouble but that’s a different story... -
I found the best text editor for basic code fixing
For a couple of days, I was looking for a simple terminal-based text editor for taking simple code notes or basic code fixing kinds of stuff.
As an aspiring developer, I really like the concept of coding without touching the mouse.
So I downloaded the king of CLI text editors, Vim.
Now, guess what happened.
Yeah, you're right. I stuck inside vim and couldn't even quit from there.
Then, I started watching a bunch of tutorials and started reading vim's documentation.
But then I realized, I have to learn a lot of things only to operate vim and it's a pretty lengthy process.
At that time, I really needed a very simple text editor for doing basic stuff.
But, vim is not simple... you know :)
So, I had to come back to 'nano' & I was not happy enough to write codes by using 'nano'.
Suddenly, I discovered another really cool text editor called 'micro'.
It's really awesome.
It's not as advanced as vim but definitely a lot better than nano.
Micro is an open-source command-line text editor created by Zachary Yedidia.
Some basic key points of Micro:
1. It's really easy to operate.
2. It has different colours and highlights.
3. It supports syntaxes for over 70+ programming languages.
4. It has mouse support.
5. Plugins & colour schemes.
The best thing for me is colour schemes & screen split support.

You knoe, my first insights into computer programming came out of spite. I thought windows to be garbage and wanted to blame someone other than myself for my machine constantly crashing. Thus I discovered programming and down the rabbit hole. But my interest in computer science came from videogames. Portal in particular. I found the idea of GlaDOS fascinating and thought that artificial intelligence would be something interesting to research. The web then gave me Lisp, and boy was the language different from all the other languages I went through. I remember feeling super excited when Racket, Common Lisp and eventually Clojure would help me discover many different ideas. Every time I work with reduce or maps or stuff like that in other languages I always thank languages such as Clojure for having me descipher different ways of manipulating data to get a result. To this day I feel sad whenever I find that my languages do not have the same constructs that Clojure has. I mention Clojure because it is my favorite flavor of Lisp. But one thing that always remains grest to me is firing up Emacs and plugin my code to Slime or Cider and see the repl pop up waiting for something to happen. This feeling is beautiful.
Please guys, if you have not tried it, do so! You might hate it at first or push it aside. But trust me, once you get it it will really change the way you think about programming in general. Try the great Clojure for the Brave and true, and go through the third chapter succesfully. If you do not like Lisp by them then no harm done! You would at least know that there are other options.
Now, here are some cool things:
For the standard implementation, try Common Lisp
For a more modern Scheme, try Racket or Guile
For targetting the JVM try Clojure (more akin to Common Lisp) or Kawa (scheme like)
For the python AST get Hy (pun totally intended)
For JS try Clojurescript
For emacs scripting try Emacs Lisp (has way too many disasdvantages but still relatively close to common lisp)
Honorific mention to more pure functional programming languages for Haskell, F#, Ocaml.
Also worth mentioning that Js , Ruby and Python have great functional constructs.

Holy shit, finally had the time to look into tmux and also accidentally discovered you can resize the panes via ctrl+b then hold ctrl+[arrow-key] to resize it to any side, but I can't find any use for it all myself yet, since I just use some terminal emulator that has tabs or use the inbuilt virtual-desktop, still an exciting and cool thing to have played with, though I would def. change most of the hotkeys to something less capslock heavy, since it's rather awkward to first press ctrl+b then shift+2 etc.
