My Last Post on This Domain

OK guys,

I think that it is time for me to publish the last post on this blog using WordPress as a domain. As you probably already know, GitHub is my favorite company and I have decided to switch my blog to a completely new domain.

I have published a couple of posts exclusively on the new domain and backed up every post from this domain to my new address (with one exception, but I’m working on it). I feel confident now to make the switch and I started to feel really comfortable using GitHub + Jekyll as a blogging platform, so I’ve decided to drop by and say good bye to my old domain.

From now on, you can follow me on r3bl.github.io. Be sure to use the http version of the site because https version is currently not properly implemented in the code. If you run into some issue while browsing the site or you miss a feature that I had implemented on this domain, feel free to report it here.

As always, you’re more than welcome to contact me anytime on aleksandar.todorovic@mail.ru. I hope that you’ll continue to read me on my new address.

Sincerely,
Aleksandar Todorović

Da li su dobri muzički producenti ujedno i dobri psiholozi? [eksperiment]

NAPOMENA: Ovaj članak nije ograničen na neki muzički žanr, preporučujem svim čitaocima da ga pročitaju bez obzira šta da slušate.

U prethodno objavljenom postu sam već najavio svoje najnoviji rad na temu o tome da li muzika može da utiče na ponašanje određene osobe. Prije nekih 10 dana sam počeo da se bavim time i još uvijek sam fazi pisanja draftova i traženja kvalitetne literature da bih uradio rad na nivou.

Međutim, tokom mog procesa traženja materijala, naišao sam na jedan zanimljiv tvit koji tvrdi da je dobar muzički producent ujedno i dobar psiholog. Nisam ga razumio, pa sam odlučio da pročitam članak na koji se taj tvit odnosi. To me je dovelo do ovog članka u kojem se objašnjava šta je tačno muzički producent. U članku se samo nekoliko puta spominje ta izjava bez detaljnog objašnjenja kako tačno muzički producenti utiču na psihu kod ljudi, temu koju objašnjavam u svom radu.

Da bih samo dodirnuo površinu toga, odlučio sam da malo prostudiram temu u obliku ovog posta, čisto da zaintrigiram vašu maštu.

Dakle, dobar muzički producent je ujedno i dobar psiholog. To je izjava iza koje stojim. Potrudiću se da ukratko objasnim i zašto.

Svi smo tokom svog života čuli makar jednu pjesmu u kojoj je tekstopisac pogodio neku našu bolnu tačku i natjerao nas da se osjećamo na određeni način na koji smo se osjećali. Međutim, mnogo manje pažnje se posvećuje muzičkim producentima, ljudima koji muziku ukomponuju sa tekstom i preko nje izraze svoje emocije. Zašto je to tako, trenutno ne mogu da sa sigurnošću tvrdim. Jedini razlog koji mi pada na pamet jeste taj što se samoj muzici moramo u potpunosti prepustiti da bi ona izazvala u nama ono nešto, dok to nije jednak slučaj i sa tekstovima u pjesmama.

Zato želim da uradim jedan eksperiment. Izazivam vas da na nekom malo kvalitetnijem ozvučenju (bile to slušalice, malo kvalitetniji zvučnici ili nešto treće) poslušate sledjeće pjesme. Dakle jedino što ne dolazi u obzir jeste slušanje preko telefona, zvučnika od laptopa ili slušalica od jedan euro. Ja ću vam tačno opisati kako će vas pjesma natjerati da se osjećate, a vi me slobodno kontaktirajte i recite mi da li sam pogriješio ili ne. Poslušajte pjesmu sa zatvorenim očima, nakon što se pjesma završi, pročitajte tekst u kojem sam opisao tačno kako ćete se osjećati dok slušate pjesmu i napravite usporedbu. Garantujem da će se mišljenja poklopiti u minimalno tri od pet slučajeva.

Prva pjesma: Netsky – Lost In This World

Sam žanr ove pjesme vam se možda nije svidio, ali ste se osjećali uznemireno dok ste je slušali. Kroz misli vam je prošla osoba koju ste nekad imali, ali je izgubili. Mislili ste o njoj, osjećali ste se nervozno i u vama je počela da se nakuplja određena doza bijesa.

Druga pjesma: The xx – Intro

Za razliku od prvog eksperimenta, ova pjesma nije dotaknula vaše emocije u negativnom smislu. Zapravo nije ih dotakla ni u dobrom smislu. Sve što ste osjećali jeste osjećaj relaksacije, i svi problemi su nestali na tih nekoliko minuta.

Treća pjesma: Blackmill feat. Veela – Life

Zbog ove pjesme ste se osjećali srećno. Osjećali ste kako se nalazite na nekoj plaži, toplo sunce vas je grijalo, a vi ste se osjećali bespokojno. U glavi ste imali osjećaj kao da su svi problemi postepeno nestali, a do kraja pjesme ste imali osjećaj kao da ste upravo proživjeli jedan od najljepših trenutak vašeg života.

Četvrta pjesma: Noisia – Tommy’s Theme

Osjećali ste se prljavo. Zamislilili ste se u nekoj post-apokaliptičnoj situaciji u kojoj je čitav svijet uništen ljudskom glupošću. Sav bijes je u vama proradio u tom trenutku.

Peta (i posljednja) pjesma: Porter Robinson – Unison

Ovo je vrlo posebna pjesma na listi jer ne budi jedno osjećanje u slušaocima, nego više njih. U samom početku niste znali šta da očekujete i kako da se osjećate. Kada se taj dio pjesme završio i kada je krenuo drugi, osjećali ste se opušteno, svaka nota vam je odgovarala, čak i ona jedna jedina za koju ste u tom jednom trenutku pomislili da je pogrešno odsvirana. Međutim, na vaše iznenađenje, pjesma je krenula da vas diže, da se osjećate živo. I tu je završio drugi dio pjesme. U trećem dijelu pjesme ste se osjećali onako kako zamišljate da ćete da osjećate kada bi nekada probali neku drogu. Sav ovaj proces se još jednom ponovio.

Ukoliko vas je članak zaintrigirao, pozivam vas da mi se javite i da podijelite sa mnom rezultate ovog eksperimenta. Javiti mi se možete na nekoliko načina, putem mail-a, koristeći Facebok, Tviter ili komentirajući direktno ispod članka koristeći vaš WordPress nalog.

What exactly is a hacker?

Quote:
Not to be confused, hacker is a person who wants to share his knowledge about computers with others. Hacker is every person who thinks in an unconventional way. An idea that a hacker is someone who does something malicious is an idea created in Hollywood.

This is a quote from a report about a hacking convention called BalCCon 2k14 that took place for the second year in a row in Novi Sad, the second biggest city in Serbia.

I think that this quote describes perfectly what a hacker is. I feel kinda tired of all those “you call yourself a hacker, you’re going to end up in jail” conversations and Google+ posts in hacker communities where idiots ask stuff like: “teach me how to hack fb plz”.

I do realize that 95% of people don’t understand us who call ourselves hackers and I do realize that they will probably never learn, but I feel so tired of this that I had to share this quote with you.

If you’re not sure what a hacker is, I suggest you to start learning by reading this Wikipedia article about a term hacker. You will start to realize that the hacker is a much more broader term than the one you have in mind, although I don’t think that this article explains it a lot.

In the end of this post, I want to share another quote with you. This quote is from Bruce Schneier‘s book called Secrets and Lies (2000) and I think that this definition covers it all.

Quote
A hacker is someone who thinks outside the box. It’s someone who discards conventional wisdom, and does something else instead. It’s someone who looks at the edge and wonders what’s beyond. It’s someone who sees a set of rules and wonders what happens if you don’t follow them. A hacker is someone who experiments with the limitations of systems for intellectual curiosity.

EDIT:
Here are some other articles written about what a term hacker is.

elementary OS – Savršena distribucija za mene

Sada sam tek shvatio da iako mi je blog pun postova o Linuksu, trenutno nemam niti jedan post posvećen u potpunosti distribuciji koja je zadovoljila sve kriterijume da bude savršeni operativni sistem za moje potrebe: elementary OS.

Već sam pisao ponešto o svojem putu koji me je doveo sve do elementary-a kada sam se pridružio #budiUbuntu akciji blogeraša sa naših prostora u ovom postu, tako da se neću puno zadržavati tu nego ću vam ispričati zašto je baš elementary OS savršena distribucija za mene.

Ako ste ikada čuli za elementary OS, već znate da je prelijep. Nastao je kao fork Ubuntu-a sa željom da ga učine ljepšim. Prva verzija se zvala Jupiter i nemam ama baš nikakvih iskustva sa tom verzijom. Nakon toga slijedi Luna, i dalje aktuelna verzija elementary-a bazirana na Ubuntu 12.04 verziji i tu počinje moje putovanje, koje se sada nastavlja sa beta verzijama sledjećeg u nizu odličnih proizvoda elementary porodice: Freya.

Pa šta ga izdvaja iz većine toliko da ga smatram savršenim operativnim sistemom? Prije svega, naravno, moram da izdvojim njegovu ljepotu. Dosta je minimalističan sistem, nakon svakog mog klika operativni sistem se odaziva istovremeno, nešto na šta nisam baš navikao koristeći KDE distribucije i Prozore u prošlosti. Tu je i odličan Ubuntu repozitorij programa, tako da se uopšte ne brinem za to da postoji neki program pisan za Linuks platformu koji ja ne mogu da pokrenem.

elementary koristi vlastiti DE pod nazivom Pantheon, DE koji radi savršeno i dolazi pred-instaliran sa svim programima koji će vam ikada biti potrebni: za slušanje muzike, gledanje videa i fotografija, čitanje dokumenata, pretraživanje interneta, čitanje mailova i slično. Svaki od programa je jednostavno prelijep i većinu nisam nikada ni promjenio, međutim neki od tih programa jednostavno ne pružaju dovoljno mogućnosti za mene, tako da konstantno preferiram Firefox umjesto Midorija, Thunderbird mi zamjenjuje Geary, a što se filmova tiče jednostavno nikada ni na jednoj platformi nisam uspio da se odviknem od korišćenja VLC plejera, bez obzira na to koliko je Audience savršen program i radi bez ikakvih poteškoća.

Sistem jeste uveliko zatvoren i na sve strane se može čitati o tome kako njegovi developeri u dizajnu u mnogo čemu kopiraju Mac, međutim ne smatram ga kopijom Mac operativnog sistema iako postoje neke sličnosti koje ne mogu da se ne primjete.

Jednostavno obožavam to što je sistem minimalistički i funkcionalan. Ukoliko se pronađe neka stvar koja mi ne odgovara (tipa nedostatak minimise opcije u programima), poprilično je lako pronaći rješenje za tako nešto. Ukoliko se javi neki problem koji je potrebno riješiti, to što je sistem baziran na Ubuntu-u je veliki plus i većina rješenja se može naći tako što se u internet tražilici unese opis problema i na kraju doda riječ elementary ili Ubuntu.

Postoji neka draž u praćenju razvoja nekog operativnog sistema. To sam po prvi put osjetio kada sam instalirao Beta 1 verziju nove verzije operativnog sistema pod nazivom Freya. Iako mi se nakon same instalacije operativnog sistema promjene nisu činile toliko drastične da je potrebna nova verzija operativnog sistema za tako nešto, ekipa koja stoji iza elementary OS-a radi svakodnevno da donesu neke nove funkcije, neke nove izmjene u dizajnu i riješe neke nove bagove koje su mučile ovaj operativni sistem. Danas, nekoliko dana od Freya Beta 2 verzije, novi elementary se polako oblikuje u nešto fantastično. U nešto nevjerovatno. Neopisiv je osjećaj ponosa koji imam zbog toga što sam pratio to sve i učestvovao u njegovoj izradi prijavljivanjem ponekog baga i učestvovanjem u diskusiji u odličnoj službenoj Google+ zajednici (koja je i jedini razlog zašto koristim Google+ kao društvenu mrežu). Skoro svaki dan se iznenadim vrteći standardne komande za update-ovanje sistema u Terminal-u otkrivajući nove mogućnosti koje mi ovaj operativni sistem pruža.

Kombinacija prelijepog minimalističkog izgleda, ogromna količina dostupnog softvera, lakoća prilagođavanja sitnih problema koji me muče, lakoća pronalaska rješenja za probleme sa kojima se susrećem, odlična zajednica i fantastičan izgled (nešto što se ne može dovoljno puta naglasiti) su bila dobitna kombinacija za mene. Sada stojim u potpunosti iza elementary projekta, finansijski ih podržavam kad god sam u mogućnosti, i preporučujem elementary projekat svakom prilikom na koju naletim, pa tako i sa ovim postom.

Nisam počeo da pišem ovaj post sa ciljem da vas nagovorim da pređete na elementary (mada, naravno, jedna preokrenuta duša za mene znači mnogo). Smatram da je odabir prave distribucije proces sa kojim se svaki potencijalni Linuksaš sam treba suočiti i istražiti mnoge opcije prije nego što se odluči za konačno rješenje. Ovaj post pišem čisto iz razloga da navedem neke razloge zašto je elementary OS savršen operativni sistem za mene.

Dronovi – moja perspektiva

Dakle u zadnje vrijeme se digla tolika frka oko dronova da sam jednostavno morao da im posvetim prostora na svom blogu. Postaju dio naše svakodnevnice, u mom gradu već ima jedan i imao sam prilike izbliza da vidim kako tačno funkcioniše.

Svi smo već upoznati sa incidentom sa dronom na utakmici između Srbije i Albanije, a evo prije nekoliko minuta sam otkrio da će dronovi da budu i na današnjoj vojnoj paradi u Srbiji.

Da počnemo sa tim šta su dronovi. Većina nas je nekad tokom našeg života imala priliku da vidi automobil ili neki letjeći objekat na daljinsko upravljanje. E pa dronovi su upravo to, igračkice na daljinsko upravljanje koje hodaju nebom, imaju malo veći domet nego što smo navikli da imamo u igračkama i koštaju mnogo skuplje. Pa zašto se digla tolika frka oko njih?

Dronovi mogu da imaju razne svrhe, od onih vojnih u kojima vojni službenici mogu da ih koriste da bi bombardovali mete, bio razlog za to opravdan ili ne, do snimanja nekog događaja iz ptičje perspektive. Naravno, dronovima može da upravlja samo onaj koji u rukama drži daljinski upravljač, tako da postoji šansa da ih upravljaju tako da proviruju kroz prozore vašeg kupatila dok se tuširate ili slično, u zavisnosti od toga šta njegov vlasnik smatra zanimljivim.

Shvatio sam da su dronovi dio naše sadašnjice i budućnosti kada sam vidio video snimak na YouTube-u u kome je moj kvart (a i mnogo veći dio grada) snimljen iz ptičje perspektive. Prva reakcija mi je bila da je tako nešto nedopustivo, ali kada sam malo bolje pogledao snimak shvatio sam da snimak izgleda predivno, jedinstveno i nešto što nikada prije nijedna tehnologija nije uspjela da mi omogući. Pošto sam veliki frik što se tiče privatnosti, kroz glavu mi je prošla ideja da bih vjerovatno pokušao da ga skinem da sam bio svjestan da se moj kvart snima i da sam bio upoznat sa time, iako nikakvog govora o invaziji na moju privatnost nije bilo u spomenutom videu. Na tome se sve završilo.

Kasnije sam sa istim dronom imao neka daljnja iskustva, počevši od toga da su iz ptičje perspektive mnogo bolje prikazane posljedice poplava u mom gradu, pa sve do toga dok nisam upoznao vlasnika drona i po prvi put ga vidio uživo tokom jednog događaja u kome su video snimci snimljeni dronom pomogli da se snimi ovaj video u kome je sumiran cijeli dvodnevni događaj.

Na tom događaju sam imao priliku da radim i dron je stavljen na svega tridesetak centimetara od mojih nogu. Neću da lažem i prizaću da mi je u nekoliko navrata palo na pamet to da ga nagazim nogom i da ga na taj način onesposobim, međutim suzdržao sam se od toga shvativši koliki je to finansijski udar na džep i da zapravo može da donese toliko novih i pozitivnih načina za korištenje.

Zaključak: Dronovi su dio naše sadašnjosti i naše budućnosti. Mogu da se koriste u razne svrhe. Neke od njih su vrlo pozitivne, a neke vrlo negativne. I dalje ne postoje regulacije o njihovom korištenju i poznavajući državu u kojoj živim potrajaće još nekoliko godina dok se regulative ne donesu. Jedino što možemo da uradimo trenutno jeste da vjerujemo da ih oni koji ih posjeduju koriste u dobrim svrhama. O da, ako imate viška para u džepu, svakako kupite jedan. Doživićete mnoge zanimljive situacije u njihovom korišćenju.

Confession: Microsoft Is Not So Bad

There’s something I need to confess. Even though I’m a hardcore Linux and free software advocate, I have to say that Microsoft, as a company, is not so bad. So, why am I saying this?

I’ve never paid a single euro for any Microsoft product. I was running cracked software like 95% of people in my country. Now this is not a secret at all. My father runs a small company (around 10 of employees) and I was doing some research about how licensing works in my country. I was amazed. As it turns out, the companies are required to have licensed software, but, if the inspection comes, they will look at a specific list of software and they’ll ask you if you have a license for those programs. What I’m trying to say is that a company only needs to have legal operating system, legal office suite and that’s about it. Add some Adobe products if you use them inside of your company and you’re good to go! Now, the situation gets even worse when we focus on personal users. No-one will ever ask you for a license. It’s like this word doesn’t even exist in my country.

Anyway, back to the story. So, I was running cracked Windows software until a year and a half. Then I found out about the world of Linux and I’ve never looked back. But, being a student and using nothing but open source technology is really hard in a country like mine (and practically anywhere else in the world!). So, my first year began and they required more and more of proprietary software for us to have. Most of them are developed by Microsoft. But, we also got a DreamSpark account, so most of the software they required from us were free of charge. That’s how I got my Microsoft Visio, Microsoft Visual Studio and stuff like that, all for nothing. After that, number of unlicensed programs I had from Microsoft was down to two.

As I’ve said earlier in the story, my father is running a small company. After catastrophical floods that hit south-east part of Europe in this year, my father had to start his job all over. So what he did is he bought a new laptop for himself and he needed to buy Microsoft’s Office license. All they had in as store we looked up was a single license for Office 365 Home Plus. He decided to take it. What I’ve found out after that is that this license can be used by five email addresses legally. He used the first one for his laptop, and I used the second for mine. Also got some extra space in OneDrive and some free premium Skype minutes. And now, I’m down to one, and it’s the main one: Microsoft’s Windows 8.1. Not sure how I will get the license for it, but I’m sure I somehow will. The license costs somewhere around 100 euros, which is about the same as the amount of money I spend on food, cigarettes and going out in a month.

Today, while I was downloading Microsoft Visio from my DreamSpark account, I found out something else. I found out that I have a free license for Windows Store in my DreamSpark account. Oh, and also, I got an access to Microsoft Virtual Academy with a lot of courses and I got some books for free as well.

So, to summarize things up, I got a lot of software from Microsoft and I didn’t actually pay anything to use it. I got only a couple of software products without a license for now but I’m working on replacing them with something legal. And I’m still trying to find my Linux alternative to elementary OS. While waiting for Freya, I’m spending most of my time in Windows looking for some alternative I will use until Freya is released. No luck for now.

I trust Microsoft a lot more than I trust Google.

Blogilo + WordPress integration is terrible!

First of all, sorry about the design of my previous post. I was trying Blogilo as a program for posting entries and the result was horrible! What I did is write down a post in LO Writer (need spelling while I write), copied it to Blogilo and clicked submit. The font was terrible, and I had to edit a post from a web interface because somewhere between my Blogilo and my blog some spaces just disappered!

Anyway, now I’m writing in QTM and I hope the post will be formated better before I write my next post in it.

Flashback: My First Steps in Hacking

I was always a curious guy. I was always wondering how do some things work, but I just didn’t know how to find out about it. I, at the time, followed Discovery Channel, Viasat Explorer and other scientific shows because I wanted to know more. I would write down everything I thought it was fun to learn in my little notebook as a reference if I needed to learn more about that. I didn’t prepare for doing something like that. That’s why my notes were messy and Icouldn’t do anything about it. And of course, at the time, I did not have a computer or internet or smartphone or anything like that.

So,years later, I finally got internet connection! I was 16 years old back then. Yup, I lived 16 years without the internet and I can’t be happier about it. I had a nice childhood. Anyway, when I finally got an access to the internet, I did spend two years doing nothing and exploring the power of internet. I used Facebook a lot, used Skype, YouTube, and basically got an account in every social site ever. I was senior in high-school when I learned a thing or two about computers. I already mastered Pascal and Delphi, I knew some networking basics and I knew a lot about building my own desktop computer. But in my senior year, I was learning object-oriented programming. And while I was learning Visual Basic (6.0 was theversion my school decided to teach), I needed to do my final exam using Visual Basic, some basic printing app that will connect to MySQL database my friend was doing and print stuff from it on a specifically designed pieces of paper.

I didn’t want to do it Visual Basic 6.0. That version was sooo old! And I needed some support looking things up on the internet! So I decided I should download Visual Studio 2012. And I did. And I learned programming in Visual Basic that’s four or five versions more advanced than the version they taught us in school. I felt so proud!

In the end, I didn’t manage to finish the whole final exam. The app was full of bugs and I didn’t like it. While I was presenting my final work to a couple my teachers I managed to socially engineer them (at the time, I had no idea what social engineering is exactly, but stillmanaged to pull it off) and I got the highest grade without everactually running my program! Damn that felt so good.

After that, my high-school was finished and I had some spare months until my collage begins. I started being curious. I wanted to know what that s represents in https. So I started learning, and learning. I did DDoS a couple of websites, did some automated SQL injection using Havij accessed some admin panels using passwords I extracted using Havij and that was pretty much the whole scope of my hacking back then.

Man, Networking is Hard!

So, I started my college education last October. First semester I wasn’t very good. I passed tree of five subjects I was supposed to pass and I got pretty much amazing grades in the subjects I did pass. But now, during the second semester, I started learning for my Cisco CCNA certificate. That certificate was the reason I decided to go on this collage (although, to be honest, my choice was very limited considering my financial situation at the time).

Now, I came to the end of the second semester. In my R&S course (first course in the path to CCNA certificate), I wasn’t very active. I didn’t go to all of the classes in that course I wasn’t very regular in lab exercises. I did not study every week and I had more and more materials to learn. I knew that, but I just didn’t pay attention. I took collage for granted and now I have a problem.

Tomorrow is my final test in my R&S course and I’m stuck. I did try to study for it as much as I could in the last ten days. I managed to learn first eight chapters, but I got stuck during the chapter nine. I just can’t understand subnetting and it’s just a big pain in the butt for me. I lost my concentration and now I have no idea what to do. I studied that chapter yesterday. I’ve spent pretty much all of my day studying it and I still couldn’t finish a basic subnetting in Packet Tracer. Now, I’m trying to do the same, but I just cannot concentrate at all. And, I still have two more chapter to go through after I finish this one.

Passing this exam is not going to be easy at all, but I will give my best. After all, being a cybersecurity specialist is my dream for a couple of years, and I just can’t be that if I don’t understand how networks actually work. This is going to be a long night.

Flashback: My first cybersecurity “discovery”

So, when I was 12 years old (at least I think I was) I didn’t have a functioning computer. My father contacted one of my neighbor and he had a spare laptop he didn’t use for a long time. He gave it to my family and I finally had something to amuse me.

The year was 2006. I was living in a small village located in northern Bosnia & Herzegovina, 40 kilometers away from the nearest town. Not an ideal place to live, I know. Having an internet in a place like that in that age was a privilege that not a lot of people could afford.

So, I had a laptop that was previously used, no internet connection and not a lot of games. The laptop had Windows 98 installed. Unlike my family, that neighbor that gave us that laptop had an internet access. So, I started tinkering with it to see what’s in there. I accessed system folder in that thing and after a few days I noticed a directory that sounded fun: Temporary Internet Files. That sounded like fun. I had no idea what was stored in there but I wanted to find out. So I opened a directory. It had numerous amount of subdirectories and some picture files. Hm, I wonder what kind of images were there. And then, I made my first cybersecurity discovery.

That directory was packed with porn pictures. Literally hundreds of them. I haven’t used such an old Windows system since then, but I guess my neighbor used Internet Explorer and I guess that Internet Explorer kept all of temporary pictures inside that folder back then.

At the time, I was really into command prompt. I didn’t know what it does and I didn’t know any commands on it, but I wanted to find out how to use it. So I started typing some random commands and once I typed in: help. That command gave me a list of all available cmd commands so I started to tinker with my laptop. I managed to do some basic changes to the system using cmd. I changed the time and date of the system and I couldn’t be more proud of me than I was back then.

So, to combine these two stories. I knew about that Temporary Internet Files folder and I didn’t know pretty much anything about cmd and what it does. I remember once I opened up my cmd, pressed Ctrl+Enter (keyboard shortcut that opened cmd in full screen back then). So I started typing this long text as a command. That text included my opinion about that neighbor after I discovered that directory. Yeah, you could only imagine what a 12 year old boy would think about some friend of his father after he discovered that. So I typed it and at the end I wrote a sentence that basically said: If you ever read this, stay away from John Doe! And I pressed enter. The command did nothing of course, it was just some plain text written in my native language. I know, what a dumb thing to do.

So, I never looked at that neighbor the same after that of course. I felt like a detective that found out something valuable. I remember coming to their house one day with my family, playing with his daughters, and looking for a chance to somehow get in his bedroom unnoticed so I could find out more. Yeah, I thought he was a freaking child molester or something. In the end, I didn’t get the chance to get to his bedroom unnoticed, so I gave up.

After that, that laptop got some hardware problems and it eventually stopped working. My detective story has ended there. But, six or seven years later, I started studying more about computer networks so I could protect people like my poor neighbor who just wanted to watch some porn videos unnoticed. And so, my journey into cybersecurity field has begun.
