Search - "blackboard"
Another story on the spirit of wk93. TL;DR I DOS'd the whole campus network for some beers.
In highschool teachers had this blackboard system (a sort of moodle) and we used to have really lazy teachers who only read the PowerPoint presentations and made us take notes. One day I was fed up with their bullshit and figured these lazy ass professors wouldn't "teach" crap as soon as there was no internet connection...so the race was on...
10 minutes before the bell rang a friend and I managed to break in into a computer lab, I booted up Kali and searched for the access points, 3 routers through the building all with CISCO OS.
I figured they had all the default configs, time was running out so I decided to Smurf the three access points with the lab's IP range, scheduled an automatic shutdown in 2 hours and blocked the PC. The bell rang and as predicted, no internet, no class, my friends and I used that free time to go to a bar (on a Monday afternoon).
Funny side note, since the 3 routers were down the whole network collapsed, no cameras, no access control, no faculty network or any network. We kept doing it and every time we did campus security would be desperately searching for someone with a black hoodie.8
Love how a teacher of mine described IO wait for CPUs on a blackboard.
"That's calculation time." *draws three small lines on the blackboard* And this is IO wait. *draws a really long line, goes out of the class, out of the school, comes back* "Yes, this is IO wait. No matter how good and fast your CPU in your gaming PC is, if your hard drive is shit, everything is shit."4
Interviewer : "Do you know SQL ?"
Me : "Yes sir. I know SQL and I prefer NoSQL."
Interviewer : "So you know SQL and you don't want to do it for our company ?? This is arrogant !! "9
My teachers rant: "Who invented whiteboard markers? *trying to write some code on the board, but the marker went dry* What every happened to black boards and chalk. Chalk never gets dry.... I going to have to look that up" LOL, man I love him. He is so old that its funny and cute at the same time15
Beware, this is gonna be a long one.
Today, in university, our professor wanted us to do an algorithm where a number was given in input, and we had to see if that number was, as she put it, "triangular".
3 is triangular because it's 1+2.
6 is triangular because it's 1+2+3.
10 is triangular because it's 1+2+3+4.
And so on.
While she was explaining this, I was programming it on my phone (because I didn't bring a PC there).
In about 10 minutes I completed it.
This student who was beside me, which I didn't know until today (I'm still in my first year here), saw me programming it, and when I finished it, he looked at it and said: "It takes too much time, like this."
So he spent another like 5-10 minutes """fixing""" it, and then showed it to me: "Here, now it's better."
Do you want to know what he did?
The only thing he did was putting a for cycle instead of my while cycle.
And he didn't even do it properly!
He put an else statement inside the brackets of an if, and some variables weren't correct.
You call that making a program more efficient? Deficient is more like it.
Also, like 5-10 minutes after I did it on my phone, on my own, I looked at the prof's desk: a guy (who apparently is "the best") wrote his algorithm on the blackboard, and the whole fucking class applauded.
Later, I saw on our Whatsapp group that someone sent a photo of him writing on the blackboard, with the caption "The student surpasses the teacher." Others agreed.
I replied with: "For the record, I did this algorithm in 10 minutes."
An asshole replied: "You'll never be superior to the master"
Fuck off. -.-"
...I'll show them.22
I put both my username and password as "incorrect". So that everytime i mess up, my computer reminds me that my login is incorrect!6
You wanted to hear more about my "glorious" teacher. I deliver. So get a cup of tea, take a seat and prepare for insanity.
As I already told in a comment my programming teacher is one special snowflake who lives in his personal bubble. We have final exams in less than a month and he spents at least half a lesson talking about vanishing bees and missing plants from his garden. Other topics he likes to talk about (and tries to turn every freaking conversation into at least one of these):
1. Other students and their stupidity
2. Diesel scandal
3. His sick wife
4. "Why does noone read newspapers anymore?"
5. Why he can't teach Java but really really really wants to and everyone hates him and forces him to do C#.
Even if I try to interrupt him he'll go on until he thinks we gained some "common knowledge" - this is how he justifies these topics.
Everytime he introduced us to a new command he compared it to Java and sometimes he even falsely corrects code because he confuses them.
We are only 6 people including me (another story for another time) and he is not able to help everyone during a 90min lesson. He normally sticks with one person for at least one hour and just talks to them or even do their tasks. This is really annoying if you have a simple question. He won't answer you until he's finished whatever he's doing.
Most of the time he doesn't seem to understand what he's talking about/trying to teach us. He's muttering statements from our textbook to himself switching halfway through to another sentence while drawing not decipherable shit on the blackboard.
Another gem are his "guidelines" for classtests. We are allowed to use any command we know. Except the ones we learned not in class. And the ones he doesn't like. And the ones he doesn't want to exist. And of course not the ones which make you're life easier. So basically we are bound to use his favourite commands or we won't get a good grade. Example: use an array. List is not allowed. Never.
He has some weird fetish with arrays.
I once presented him perfectly fine code I wrote in my freetime and asked what some warnings meant. (Was because of different Visual studio versions as I learned later.) He scolded me for using things he didn't taught us yet and ranted about how I'm pressuring him into rushing these things now - I never wanted to show this to my classmates nor was this anything else than a project for fun and learning something new. (FYI the "new stuff" where classes and objects because i was tired of kilometers of spaghetti code). His rant went on a good 20minutes and - obviously - he didn't answer my question. I asked my fiance that evening and he explained it to me.
This should it be for this time. I'm sure I have more stories to tell for another time!
Thank you for reading. ^^5
The existence of Blackboard pains me greatly.10
Today teacher started to calculate some thing on blackboard and result was 404 then i started to laught and said "i cannot see the result i think you have a problem fix it" he was like what classmates started to laught too after i teach teacher what 404 means in programming life he was like woow finally got that haha.
So, I decided to post this based on @Morningstar's conundrum.
I'm dissatisfied with the laptop market.
Why THE FUCK should I have to buy a gaming laptop with a GTX 1070 or 1080 to get a decent amount of RAM and a fucking great processor?
I don't game. I program. I don't even own a fucking Steam library, for clarification. Never have I ever bought a game on Steam. Disproving the notion that I might have a games library out of the way, I run Linux. Antergos (Arch-based) is my daily driver.
So, in 2017 I went on a laptop hunt. I wanted something with decent specs. Ultimately ended up going with the system76 Galago Pro (which I love the form factor of, it's nice as hell and people recognize the brand for some fucking reason). Matter of fact, one of my profs wanted to know how I accessed our LMS (Blackboard) and I showed him Chromium....his mind was blown: "Ir's not just text!"
That aside, why the fuck are Dell and system76 the only ones with decent portables geared towards developers? I hate the prospect of having to buy some clunky-ass Republic of Gamers piece of shit just to have some sort of decent development machine...
This is a notice to OEMs: yall need to quit making shit hardware and gaming hardware with no mid-range compromise. Shit hardware is defined as the "It runs Excel and that's all the consumer needs" and gaming hardware is "Let's put fucking everything in there - including a decent processor, RAM, and a GTX/Radeon card."
Mid-range that is true - good hardware that handles video editing and other CPU/RAM-intensive tasks and compiling and whatnot but NOT graphics-intensive shit like gaming - is hard to come by. Dell offers my definition of "mid-range" through Sputnik's Ubuntu-powered XPS models and what have you, and system76 has a couple of models that I more or less wish I had money for but don't.
TBH I don't give two fucks about the desktop market. That's a non-issue because I can apply the logic that if you want something done right, do it yourself: I can build a desktop. But not a laptop - at least not in a feasible way.31
Definitely a blackboard or whiteboard. Definitely helps in the modularity of my code. I love it when I spend 90% of my time drawing out my idea on a blackboard, implementing it and having it be super modular.3
Cengage get your shit together.
I'm paying $200 fucking dollars to use your online learning platforms, not actually fucking work. As in don't freeze for 5 seconds after I type 2 letters into your search bar.
Oh and BlackBoard you like of shit. Your text boxes are absolutely fucking broken. Thank God we're ditching you, you pile of shit.6
Google was hiring till the last week. If you didn't apply, don't worry. They already has all your information. They will call you if they like you.6
Java teacher writes code on blackboard in comp lab
He tells us to try it out at our workstations.
We do. The code does work. We tell him.
He says: "There is something wrong with your compiler..."
Question is...we were around 30 students. Can all our compilers not work if we had used the lab before and the code we run worked clean??!?!?!?
We were flabbergasted2
I’ve spent 2 weeks trying to simply automate logging into my damn school’s blackboard but this ducking popup won’t freaking let me access it. I’ve tried selenium. I’ve used beautifulsoup and requests. I’ve even tried a tool called mechanize with python
But I’ve now realized I simply have no damn idea what I’m doing. I’ve read and tried way too many stack overflow articles and I’m just sick of this damn popup
If I can’t figure it out by the end of the upcoming thanksgiving break I’m dropping this damn project until I learn enough to utilize the blackboard API’s. I’m a little sure those will help18
I was tasked to evaluate wherever a customer could use an implementation of OTRS ( https://otrs.com/ )
Is it just me or is there no information on this site apart from <OTRS> will make your life better! <OTRS> will cure AIDS! <OTRS> will end world hunger!
This site is trying to use its fucking product name in every god damn sentence. <OTRS>. Everytime <OTRS> is mentioned it is fucking bold printed! My eyes are bleeding within 2 minutes of visiting this site.
I can't get any information about what excatly it is apart from their catchphrase: OTRS (again, bold. I'll refrain from putting it in <> from now, i think you got the point) is a customizable support desk software that manages workflows and structures communication so there are no limits to what your service team can achieve.
So, it's a support desk software you can customize. Great. What does it do?
"Whether you deal with thousands of inquiries and incidents daily [...] you’ll need digital structures that integrate standardized processes
and make communication transparent between teams and departments,
as well as for external customers."
Great, but what does it do?
"Reduce costs and improve satisfaction by structuring customer service communication with OTRS."
Great, BUT WHAT DOES IT DO?
"Manage incidents simply and uncover the data needed to make forward-thinking strategy decisions. OTRS is an ITSM solution that scales and adapts to your changing business needs."
W H A T D O E S I T D O ?!
Okay fuck that, maybe the product page has something to say.
Hm... A link on the bottom of the page says it is a feature list ( https://otrs.com/product-otrs/... )
Ah great, so i got a rough idea about what it is. Our customer wants a blackboard solution with a window you can pin to your desktop and also has a basic level of access control.
So it seems to be way to overloaded on features to recommend it to them. Well, let's see if can at least do everything they want. So i need screenshots of the application. Does the site show any of them? I dare you to find out.
Spoiler: It does not. FFS. The only pictures they show you are fucking mock ups and the rest is stock photos.
Alright, onwards to Google Images then.
Ah, so it's a ticket system then. Great, the site did not really communicate that at all.
Awesome, that's not what i wanted at all. That's not even what the customer wanted at all! Who fucking thought that OTRS was a good idea for them!
Last week I was studying Cocos2d-python, I had been awake for something like 35 hours, kept alive by cocacola and coffee, and while debugging I started to hear my rubber ducks talking, I've written their instructions on a blackboard, and now I'm working on that project...
And I was there like everything was normal, I had more caffeine and sugar in my body than water, I remember clearly saying "thanks weird talking duck!"2
So here's how the story goes.
I was in my academic writing class the other day and we were learning about APA formatting for our argumentative essays. We have a blackboard, whiteboard, projector connected to a pc and even a lovely projector screen to present with in the classroom.
I sit at the front right of the room. Closest to the window(it's behind me as all the desks face inwards)
Professor walks up to front of class and says we are going to learn how to format our typed essays properly.
Awesome, I thought. Pulled out my XPS laptop and fired it up. As I was making a new Word document, I hear scratching. I look up and the professor is writing with CHALK on the BLACKBOARD. I was astonished. Making matters worse, she started from the far left of the board from which the glare from the window was the greatest. I could not see anything. And from that point on I knew this class was going to be abysmal.
What was so depressing was my professor never once touched the projector. Scraping and erasing. Over and over. Couldn't see if it was a period or a comma after the first initial.
My eyes were never so dry from squinting, rolling my eyes and face-palming over and over. After an hour and 15 minute class, I was not far away from drowning my XPS in my tears.6
With a recent HAProxy update on our reverse proxy VM I decided to enable http/2, disable TLS 1.0 and drop support for non forward-secrecy ciphers.
Tested our sites in Chrome and Firefox, all was well, went to bed.
Next morning a medium-critical havock went loose. Our ERP system couldn't create tickets in our ticket system anymore, the ticket systems Outlook AddIn refused to connect, the mobile app we use to access our anti-spam appliance wouldn't connect although our internal blackboard app still connected over the same load balancer without any issues.
So i declared a 10min maintenance window and disabled HTTP/2, thinking that this was the culprit.
Nope. No dice.
Okay, i thought, enable TLS 1.0 again.
Suddenly the ticket system related stuff starts to work again.
So since both the ERP system and the AddIn run on .NET i dug through the .NET documentation and found out that for some fucking reason even in the newest .NET framework version (4.7.2) you have to explicitly enable TLS 1.1 and 1.2 or else you just get a 'socket reset' error. Why the fuck?!
Okay, now that i had the ticket system out of the way i enabled HTTP/2 and verified that everything still works.
It did, nice.
The anti-spam appliance app still did not work however, so i enabled one non-pfs cipher in the OpenSSL config and tested the app.
Behold, it worked.
I'm currently creating a ticket with them asking politely why the fuck their app has pfs-ciphers disabled.
And I thought disabling DEPRECEATED tech wouldn't be an issue... Wrong...
Fucking shitty ass educational products fucking really suck. Literally, one of the schools we work for has a piece of software called Blackboard that seems great and all until you realize that its written in Java and you have students and teachers who barely know how to turn on a computer using this thing! I'm not even kidding when I say that one student can bring the entire thing to its knees just by causing it to throw a NullPointerException and to make matters worse teachers are allowed to customize their "classrooms" which as part of that they are allowed to add plugins. Some of which also cause fucking headaches and NullPointerExceptions. The least these fuckers could have done was switched their code to Kotlin or something that could actually handle improper types without crashing the whole damn thing.6
Logging into my schools blackboard using selenium is only redirected on school WiFi
Outside school WiFi I go directly to the site. But on the school WiFi it pauses on a redirect page with a link that loops back to the redirect when grabbed by selenium And selenium fails
In our class we have one subject where we take notes on one shared Google docs document. To be honest, this may be the worst "teamwork" that I every had to deal with.
• Simply copying the stuff from the blackboard:
• Missing context
• document consists of keywords and occasional sentences
• These fucking deep nested lists
• No quality control whatsoever
--> nobody fucking cares
• What, nobody made notes for this point?
• Any attempt to speak up result in me being scolded
• Be me, the only one not shopping on amazon instead of taking notes
• Wtf does this mean, where's the context
• one line of code without needed context code
No quality, no Motivation, no better alternatives, no fun.
If Brave crashes one more fucking time I'm switching to Firefox. Between the rendering issues on my school's blackboard and the crashes I'm fed up with it.5
Well, not best experience per se, but most memorable one.
So I am accepted to CS program at the university - happy days!
First lecture of the first day of the first semester in the first year...
...It just had to be that guy. He was famous for for his strictness among the faculty as we later found out.
But, the lecture. It's 8.25 am, I am making my way into auditorium, and it's filled with freshmen like me, of course. Instead of cheerful chatter noise I hear literally silence. What the? I catch the glimpse of the blackboard - the professor is there, hard at work writing out some stuff that can't comprehend. Double checked the name of the lecture - computer architecture.
8.30 - so it begins, I remember taking a place along the front rows in order to see more clearly. Professor turns to us and just starts the lecture, saying that he'll introduce himself later at the end and there is no time to waste. OK...
And he just dumps the layout of x86 computer architecture and a mixture of basic ASM jargon on us WITHOUT TURNING TO US FOR LIKE 30 MINS while writing things out on the blackboard.
The he finally turns 180 degrees very quickly, evaluates our expression (I know mine was WTF is this I don't even understand half the words), sighs, turns back and continues with the lecture.
Messed up with my virtualServers in my router.
Now I need a VPN, to connect with internet in my own home.😞😞
