Month #1 at CS University. We write C on the terminal, with nano. No vi no ide no highlighting. Neither makefile is allowed. Professors don't know what git is.

I am pissed off.

Why would you even?

Preach it sister.

My first Drone
Arduino nano + L293D + hc-06
Objective: learn how to use Bluetooth with Arduino.
V 0.1 (no direction, commands by serial terminal).

Ladies and gentlemen.

Back in 2009 when I started coding, some dickhead told me to not learn Vim because professional developers normally use IDEs for shit instead of text editors.

Being the kind of person that I am, I shrugged him off as the cocksucker that he was and decided to learn Vim anyway.

Fast forward to 2015 up to 2018

At work. For fucking everything since it is what you have when you ssh into a server and lemme tell ya this:

I you guys thought being a Vim master ain't dropping no one's panties....boy u wrong af.

And nano is fine too, but why settle for less when you can be a complete vim black wizard?

I have a confession to make:

You're never really lost until you have no internet and nano isn't installed .-.

In fact I'm a sinful dev, so that I can't easily decide which one is worst. From indenting with tabs, or using nano instead of vim/emacs, to hardcoding database credentials on server, to many hacks and workarounds I use as actual "fixes" when the deadline is upon me and I've tried all I could. But it always led only to my own regret. For instance, my latest sin was that I prefered Debian over Arch and used proprietary graphic drivers to speed up my new setup. But ended up with a curse from St. Ignucius. (check my last rant)

But my worst sin probably goes to when I was "printf-debugging" some issue for a GSM controller on a raspberry pi. I forgot to remove one little print line and deployed the new "fixed" version. I didn't follow that project after that for like a month or so, when the client posted back the device and said that "it just doesn't work anymore". It seemed that raspbian didn't boot beacause the sd card was curroptted. I dd'ed through the card and I noticed that there are billions of lines of "DEBUG:: reading stream from 192.some.shitty.ip", took almost all over the 32G sdcard. Just as I suddenly remembered the cursed line I just added a month ago, I declared the sd card dead with no hesitation, dunce-commented the line (so the history would remember), implemented a time out for the thread containing it, setup a journald unit for my service and removed the redirection of process output to a log file, found a new sd card and installed everything again, and finally posted back the new "fix" to the client.

Moral: Never comfort yourself for the sins you have commited in the past kids, they certainly will come back to you. And also not to do any io especially write to a file on an SD card with ext fs, in a potentially infinite loop with no timeout.

P.S: I'd posted my last rant just before the new week rant last nigh. I really liked the St. Ignucius meme so decided to create a new one. He's very adorable :)

I’m hired as pizza making burger flipper for $12/hr since I have no formal schooling and then I am walked out back to the utility room to do what cooks REALLY DO... Secret network engineering and admin... Never fails... They always find out and I always end up replacing whatever company or person they used for tech/admin work.

Time to at least get some Oracle certs and a nano degree!

VIM! ViM! vim! Vi Improved! Emacs (Wait ignore that one). What’s this mysterious VIM? Some believe mastering this beast will provide them with untold mastery over the forces of command line editing. Others would just like to know, how you exit the bloody thing. But in essence VIM is essentially a command line text editor at heart and it’s learning curve is so high it’s a circle.

There’s a lot of posts on the inter-webs detailing how to use that cruel mistress that is VIM. But rather then focus on how to be super productive in VIM (because honestly I’ve still not got a clue). This focus on my personal journey, my numerous attempts to use VIM in my day to day work. To eventually being able to call myself a novice.

My VIM journey started in 2010 around the same time I was transiting some of my hobby projects from SVN to GIT. It was around that time, that I attempted to run “git commit” in order to commit some files into one of my repositories.

Notice I didn’t specify the “-m” flag to provide a message. So what happened next. A wild command line editor opened in order for me to specify my message, foolish me assumed this command editor was just like similar editors such as Nano. So much CTRL + C’ing CTRL + Z’ing, CTRL + X’ing and a good measure of Google, I was finally able to exit the thing. Yeah…exit it. At this moment the measure of the complexity of this thing should be kicking in already, but it’s unfair to judge it based on today’s standards of user friendly-ness. It was born in a much simpler time. Before even the mouse graced the realms of the personal computing world.

But anyhow I’ll cut to the chase, for all of you who skipped most of the post to get to this point, it’s “:q!”. That’s the keyboard command to quit…well kinda this will quit the program. But…You know what just go here: The Manual. In-fact that’s probably not going to help either, I recommend reading on :p

My curiosity was peaked. So I went off in search of a way to understand this: VIM thing. It seemed to be pretty awesome, looking at some video’s on YouTube, I could do pretty much what Sublime text could but from the terminal. Imagine ssh’ing into a server and being able to make code edits, with full autocomplete et al. That was the dream, the practice…was something different. So I decided to make the commitment and use VIM for editing one of my existing projects.

So fired the program up and watched the world burn behind me. Ahhh…why can’t I type anything, no matter what I typed nothing seemed to appear on screen. Surely I must be missing something right? Right! After firing up the old Google machine, again it would appear there is this concept known as modes. When VIm starts up it defaults to a mode called “Normal” mode, hitting keys in this mode executes commands. But “Insert” entered by hitting the “i” key allows one to insert text.

Finally I thought I think I understand how this VIM thing works, I can just use “insert” mode to insert text and the arrow keys to move around. Then when I want to execute a command, I just press “Esc” and the command such as the one for saving the file. So there I was happily editing my code using “Insert” mode and the arrow keys, but little did I know that my happiness would be short lived, the arrow keys were soon to be a thorn in my VIM journey.

Join me for part two of this rant in which we learn the untold truth about arrow keys, touch typing and vimrc created from scratch. Until next time..

:q!

I learned to exit vim, and got happy.

Server crashes, i boot into rescue mode and shit. It forces me to use vim as the texteditor, because fuck nano i guess.
Additionally, the fucking buttonboard layout changed to english instead of danish, which results in i have no fucking clue where which characters are.
Im dead.

I have just slept for a minimum of 5 hours. It is 7:47 PM atm.
Why?
We have had a damn stressful day today.
We have had a programming test, but it really was rather an exam.
Normally, you get 30 minutes for a test and 45 minutes for an exam.

In this "test" we have had to explain what 'extends' does and name a few advantages of why one should use it.
Check.
Read 3 separate texts and write the program code on paper. It was about 1 super class and 1 sub class with a test class in Java.
Check.
Task 3: Create the UML diagram of the code from above. *internally: From above? He probably means my code since there is no other code there. *Checks time*. I have about 3 minutes left. Fuck my life.*
Draws the boxes. Put the class names in each of them. A private attribute for the super class.
Teacher: Last minute!
Draw the arrow starting starting from the sub class to the super class.
Put my name on each written paper. And mentally done for the day. Couldn't finish the last task. Task 3.
During this "test", I heard the frustrations of my classmates. Seemed like everyone was pretty much pissed.
After a short discussion with the teacher who also happens to be the physics professor of a university nearby.
[If you are reading this, I hope that something bad happens to you]
The next course was about computer systems. Remember my recent rant about DNS, dhcp, ftp, web server and samba on ubuntu?
We have had the task to do the screenshots of the consoles where you proof that you have dhcp activated on win7 machine etc. Seemed ok to me. I would have been done in 10 minutes, if I would be doing this relaxed. Now the teacher tells us to change the domain names to <surnameOfEachStudent>.edu.
I was like: That's fine.
Create a new user for the samba server. Read and write directories. Change the config.
Me: That should be easy.
Create new DNS entries in the configs.
Change the IPv6 address area to 192.168.x.100-200/24 only for the dhcp server.
Change the web server's default page. Write your own text into it.
You will have 1 hour and 30 minutes of time for it.
Dumbo -ANGRY-CLIENT-: Aye. Let us first start screenshotting the default page. Oh, it says that we should access it with the domain name. I don't have that much time. Let us be creative and fake it, legally.
Changes the title element so that it looks like it has been accessed via domain name. Deletes the url and writes the domain name without pressing Enter. Screenshot. Done. Ok, let us move to the next target.
Dhcp: Change lease time. Change IP address area. Subnet mask. Router. DNS. Broadcast. Optional domain name. Save.
Switches to win7.
ipconfig /release
ipconfig /renew
Holy shit it does not work!
After changing the configs on ubuntu for a legit 30 minutes: Maybe I should change the ip of the ubuntu virtual machine itself. *me asking my old self: why did not you do that in the first place, ass hole?!*
Same previous commands on win7 console. Does not work. Hmmm...
Where could be the problem?
Check the IP of the ubuntu server once again. Fml. Ubuntu did not save when I clicked on the save button the first time I have changed it. Click on save button 10 times to make sure it really is saved now lol.
Same old procedure on win7.
Alright. Dhcp works. Screenshot.
Checks time. 40 minutes left.
DNS:It is your turn. Checks bind9 configs. sudo nano db.reverse.edu.
sudo nano db.<mysurname>.edu.
Alright. All set. It should work now.
Ping win7 from ubuntu and vice versa. Works. Ping domain name on windows 7 vm. Does not work.
Oh, I forgot to restart the bind9 server on ubuntu.
sudo service bind stop
" " " start
Check DNS server IP on win7. It looks fine.
It still doesn't work. Fuck it. I have only 20 minutes left. Samba. Let us do this!
10 minutes in. No result. I don't remember why. I already forgot why I have done for it. It was a very stressful day.
Let us try DNS again.
Oh shit. I forgot the resolver!
sudo nano /etc/resolv.conf
The previous edits are gone. Dumb me. It says it in the comments. Why did not I care about it. Fuck it.6 minutes left. Open a yt video real quick. Changes the config file. Saves it. Restarts DNS and dhcp. Closes the terminal and opens a new one. The changes do not affect them until you reopen them. That's why.
Change to win7.
Ping works. How about nsloopup.
Does not work.
Teacher: 2 minutes left!
Fuck it.
Saves the word document with the images in it. Export as pdf. Tries to access the directories of the school samba server. Does not work. It was not my fault tho. Our school server is in general very slow. It feels like they are not maintained and left alone like this in the dust from the 90s.
Friend gets the permission to put his document on a USB and give the USB to the teacher.
Sneaky me: Hey xyz, can you give me your USB real quick?
Him: sure.
Gets bombed with "do you want to format the USB?" pop-ups 10 times. Fml. Skips in a fast way.
Transfers the pdf. Plug it out. Give it back.
After this we have had to give a presentation in politics. I am done.

Show me how you made an http server with an arduino nano and an esp8266 via AT commands from the arduino, the arduino handling the clients.

No you didn't, this shit is fucking impossible.

Was helping a friend fixing apache url redirects he says I've got cent os i was a bit nervous. The configs were in httpd.conf file but as soon as i try to edit i see there is no nano editor
But there was vi editor, now I'm on call helping this dev and googling vim cheat sheet 😂😂😂😂😂, i had no idea how to edit the file. Its not that hard though.

Colleague is programming/scripting for over 5 years now (that I know of), even attended Udacity programming nano-degree.
Yet, he still writes code/scripts without a single function. How the hell can we start any programming best practices, clean code, or making steps towards TDD with this sort of mentality.
And it's not just him, it feels like a death by thousands cuts as the small things add up. I know we're Ops and not Devs and some other colleagues are trying really hard to get their work on the next level but I see no hope for the team as the whole.

nano or IDLE, depending on need.

nano is the best terminal text editor by far, as i don't wanna have to learn a new command line and 2 control modes just to type in ffffffffffucking vim and it's just powerful enough to do what is needed without extra crap on top.

IDLE is super-light-weight, has a somewhat-handy debugger if i need to see what's up when my code interacts with modules or some such, takes up very little RAM and is open-source. Works exactly as needed and no more.

It's always a matter of much is there to do and in what language...
There is the IDE-Zone, which is dominated by IntelliJ (CLion be praised when you do Rust or C++) for large stuff and heavy refactorings.

Always disputted by VS Code with synced settings. It's nice and comfy and has every imaginable language supported good enough, especially when its smaller change in native code or web/scripting stuff.

Then there is the "small changes" space, where Vim and VS Code struggle whos faster or which way sticks better in my brain...

might be you SCP stuff down from a box and edit it to re-upload, or you use the ever-present vi (no "m" unfortunately)

sometimes things are more easy for multi-caret editing (Ctrl-D or Alt-J), and sometimes you just want to ":%s/foo/bar/g" in vim.
I am sure that each of these things are perfectly possible in each of the editors, but there is just reflexes in my editor choices.

I try to stay flexible and discover strenghts of each one of my weapon of choice and did change the favorites. (Atom, Brackets, Eclipse, Netbeans, ...)

However there are some things I tried often and they are simply not working for me...

might for you. I don't care. and I'll just use some space to piss people off, because this is supposed to be a rant:

nano just feels wrong, emacs is pestilence from satan that was meant for tentacles instead of fingers, sublime does cost money but should not, gives me a constant guilty feeling (and I don't like that) that, and all the editors from various desktop environments are wasted developer ressources.

need a random number

AI says just use system time and modulus it. I'm wondering if I can get performance down lower cuz I'm doing this maybe like thousands of times a second (im too lazy to do the math rn)

found a crate called fastrand. they're all like this isn't secure for cryptography and yada yada. peak inside curious how they do it. not too sure, seems like they have a predetermined hash and they do some bitwise or something. kind of a lot to read so I don't wanna. either case seems like they're not using system time

make a test to benchmark, 10k rounds how fast is it?

430 nano seconds for system time
460 nano second for fastrand

lol
all that typing and you end up slower than system time. I'm assuming system time can be guessed as well but what's the point of fastrand if it's slower 🤔

I mean maybe on some OS systems looking up the system time might be slower? no clue
