This is more just a note for younger and less experienced devs out there...

I've been doing this for around 25 years professionally, and about 15 years more generally beyond that. I've seen a lot and done a lot, many things most developers never will: built my own OS (nothing especially amazing, but still), created my own language and compiler for it, created multiple web frameworks and UI toolkits from scratch before those things were common like they are today. I've had eleven technical books published, along with some articles. I've done interviews and speaking engagements at various user groups, meetups and conferences. I've taught classes on programming. On the job, I'm the guy that others often come to when they have a difficult problem they are having trouble solving because I seem to them to usually have the answer, or at least a gut feel that gets them on the right track. To be blunt, I've probably forgotten more about CS than a lot of devs will ever know and it's all just a natural consequence of doing this for so long.

I don't say any of this to try and impress anyone, I really don't... I say it only so that there's some weight behind what I say next:

Almost every day I feel like I'm not good enough. Sometimes, I face a challenge that feels like it might be the one that finally breaks me. I often feel like I don't have a clue what to do next. My head bangs against the wall as much as anyone and I do my fair share of yelling and screaming out of frustration. I beat myself up for every little mistake, and I make plenty.

Imposter syndrome is very real and it never truly goes away no matter what successes you've had and you have to fight the urge to feel shame when things aren't going well because you're not alone in those feelings and they can destroy even the best of us. I suppose the Torvald's and Carmack's of the world possibly don't experience it, but us mere mortals do and we probably always will - at least, I'm still waiting for it to go away!

Remember that what we do is intrinsically hard. What we do is something not everyone can do, contrary to all the "anyone can code" things people do. In some ways, it's unnatural even! Therefore, we shouldn't expect to not face tough days, and being human, the stress of those days gets to us all and causes us to doubt ourselves in a very insidious way.

But, it's okay. You're not alone. Hang in there and go easy on yourself! You'll only ever truly fail if you give up.

The best/worst code comments you have ever seen?

Mine:

//Upload didn't work, have to react:
system.println('no result');

//$Message gives out a message in the compiler log.
{$Message Hint 'Feed the cat'}

//Not really needed

//Closed source - Why even comments?

//Looks like bullshit, but it has to be done this way.

//This one's really fucked up.

//If it crashes, click again.

asm JMP START end; //because no goto XP

catch {
//shit happens
}

//OMG!!! And this works???

asm
...
mov [0], 0 //uh, maybe there is a better way of throw an exception
...
mov [0], 0 //still a strange way to notify of an error

// this makes it exiting -- in other words: unstable !!!!!

//Paranoic - can't happen, but I trust no one.

else {
//please no -.-
sleep(0);
}

//wuppdi

for (int i = random(500); i < 1000 + random(500 + random(250)); i++)
{
// Do crap, so its harder to decompile
}

//This job would be great if it wasn't for the f**king customers.

//TODO: place this peace of code somewhere else...

// Beware of bugs in the code above; I have only proved it correct, not tried it.

{$IFDEF VER93}
//Good luck
{$DEFINE VER9x}
{$ENDIF}

//THIS SHIT IS LEAKING! SOMEONE FIX IT! :)

Today was a rather funny day in school. School starts for me at 13:40 because our timetable planners are so qualified for this job.

First 2hrs: Physics, fine its good

Second 2hrs: Discrete Maths (however you want to call it)
Goal is to write a text (30 pages, 10, etc all those standard settings). Teacher prefers Latex over word, but we can do it in word if we want. We could choose a topic, I took primes because it looked the best. I decided to use latex because I'm a fetishist and it simply looks better in the end. A classmate was arguing with our teacher about ides: texmaker vs kile. And I'm like "I use vim". So my teacher is like kk

Later that class, when we actually started doing stuff I started the ssh session to my server because I don't know any good c++ compilers for win and I'm too lazy to get a portable version of cygwin (or whatever its called). So in my server I open vim and start coding my tool for Fermat Primes (Fermatsche Primzahlen, too lazy to actually translate). And this teacher seriously is the best teacher I ever met in my life. Usually teachers are like " dude r u hakin' the school server?" and I'm like bruh its just vim and I'm doing it this way because I cannot code on your PC coz I can't install a compiler. And this teacher is like "oh hey you actually use vi, all cool kids used it in 2000. I first though u were kidding and stuff..." And we continued talking about more of stuff like that and I have to say that this is the first teacher that actually understands me. Phew

Now I'm going to continue writing my 30 pages piece of trash latex doc and hope it'll end good

My two best friends has been the most influential mentors I've ever had. One is a compiler engineer at a major computing company and the other one is a security engineer at a major company in Japan.

Both have sat down and taken the time to not only teach me different aspects of the computing environment, but empowered me to learn more on my own. One project I was working on ended up tapping into both of their teachings. I took a moment to think back on when they were teaching me and felt so grateful to have such patient teachers.

The moral here is that not everyone knows what you do. What makes a good teacher is someone who takes the time to teach and empower the individual. It really goes a long way.
