Friend: Hey, can you fix my laptop? The hard drive is almost full.
Me: (Looking through his folders) Maybe it's because of this. Why do you have 3000+ files in your downloads folder? Maybe I should delete some of this.
Friend: No no, please don't touch the downloads folder, I have some very important documents there.
Me: Why don't you move them to a separate folder then? You should organize the ones you actually need and delete the rest. This folder is a complete mess.
Friend: No no, the problem is not the downloads folder, there must be something else. Can't you just uninstall some programs to free up space?
Me: I could, but I don't know which ones you actually use.
Friend: What? You should know!! You studied computer science for this!!
Me: First of all, there is not a single class in the whole 4 years of university called "How to uninstall programs and free up space on 128GB hard drives of shitty €400 computers". Second of all, I don't know why you were expecting me to find a magic button on your laptop that immediately frees up all the space in a hard drive without actually deleting anything. That's not how computers work, you know.
Friend: Hey if you didn't want to help me you could have said so in the first place.
Me: FML20 -
Someday my toaster is going to have an IP address. A bad automatic firmware update will most likely cause it to get stuck on the bagel setting until I plug a usb key in and reflash the memory.
Grandma's refrigerator will probably get viruses, lock itself and freeze all the food inside, demanding bitcoin before defrosting.
My blender will probably be used in a massive DDoS attack because Ninja's master MAC address list got leaked and the hidden control panel login is admin/admin.
Ovens will burn houses down when people call in to have them preheat on their way home from work.
Correlations between the number of times the lights are turned on and how many times the toilet is flushed will yield recommendations to run the dishwasher on Thursdays because it's simply more energy efficient.
My dog will tweet when he's hungry and my smart watch will recommend diet dog food in real-time because he's really been eating too much lately--"Do you want to setup a recurring order on Amazon fresh?"

My ISP advertises themselves as IT-nerds. I once contacted the support, not tech support, just the usual support. I wanted to use my own router instead of theirs, and the supporter actually knew how I should configure my vlan and a lot of other technical stuff.

Got fired earlier today.... I had a feeling it was coming but was hoping it wouldn’t.
I really liked the job and the work. It was difficult for me at times because the job demanded medium to advanced linux skills and knowledge for just about every issue. And I’m still a complete newbie to Linux. But I was learning new things constantly because it was a challenge.
But they said that my skills weren’t up to snuff for them or their clients, so instead of investing in training they let me go. I’m sure there’s big company politics at play and someone (or multiple people) higher up would probably rather just hire someone that already had the skillset they were looking for than invest time and money into training.
I don’t wish them any ill will. Even though I’m thoroughly pissed at the situation I’m in now.
I believe that I was a really engaged employee and driven to learn and strived to be better than I was, but I guess that didn’t matter. Or maybe it just didn’t matter enough...15 -

This is my first IoT project. It's pretty simple, but I've been very happy with the results thus far.
About this time last year, someone got into our garage and rifled through my wife's car.
I have a camera in my garage, and a Phillips Hue motion detector. Using the Hue's excellent API, I have a perl script that checks for motion every couple of seconds, and starts capturing from the camera via RTSP if it does. That video is then staged, ready to be uploaded to a digital ocean droplet if I click on a link in the mailgun-powered email that's then sent to me and my wife, along with a preview GIF of the video, created through the same ffmpeg process that pulled the capture from the camera.
Here you can see me getting home from work.

So this year I had a subject at university called "Linux internal architecture", and for the last assignment I had to write a kernel module and interact with it with a separate program written in C.
Once I had finished and tested the driver, I went on to write the other program, which was supposed to use system calls to read and write data to the module. While debugging this program (~500 lines of code) I reached the level of frustration where you just start printing absurd messages everywhere in your code to see what's wrong. So for example instead of printing "This error happened in this function", my error messages were more like "Fuck this fucking function it doesn't fucking work".
Guess who forgot to delete all those messages before sending the code to the teacher...
Also, if a specific mode is selected, the program enters a while(1) that, apart from doing what it's expected to do, also creates a file in the user's home directory called something like 'motherfucker' and appends the words 'fuck this shit' to it. INFINITELY.
I really really hope this teacher doesn't try to run the program in his own computer, or he's in for a big surprise.10 -

You know what I realized we should always say no for demo driven application development.
We should always ask for enough time do a proper development and if its not enough, shouldn’t write a single line.
Because once we deliver a working demo. Its release ready for them because its FUCKING WORKING..
And trying to explain why this is just a demo and cant be put to production is even bigger pain in the ass than saying no in the beginning.

I have a whatsapp group with my friends, none of which are techies. A while ago one of them was looking for a phone to buy, so he started looking at models, specs and all that, but got pretty confused and asked a pretty well-informed question to the group:
"Guys, what is that quad core thing?
And what is a RAM? Is it something like the processor of the phone or what? "
OK, pretty typical stuff up until this point. The guy knows nothing about this sort of things, I wouldn't criticize him or insult him or anything like that. No, that's not the problem. The problem is the person that responded to him. This... This melted my brain so much I will never forget:
"Don't worry about that, you only have to look at how many gigahertz does the processor run at. Don't worry about the number of cores or ram. The GHz are the result of the amount of ram and cores, so the more the gigahertz, the better the phone."
PD: "Also take a look at how many megapixels does the camera have if you want to take photos".

A few months ago I was working on a (totally underpaid project) where my friend and I had to basically rewrite the entire program our client was using.
So we started planning and wrote all sorts of documentation to show the client our ideas for the new flow of the program, the new structure of the GUI and a few more details of what would the inner workings of the new app. He seemed to like all those ideas and gave us the green light to go through with the project and start coding.
We spent a couple of months coding, redoing the front end from scratch (with a different framework even, so I couldn't reuse any code from the old version) and completely redesigning the back end so it would be better, faster, more scalable etc etc etc. During this process, we obviously showed the progress of the app to our client, explaining everything we had been doing, and he seemed to like every new version we showed him.
When we were in one of the last stages in development (basically sending versions of the app to the client for evaluation), the guy suddenly changed his mind. After agreeing on everything we had been showing him over the last months, he sent an email saying:
"...the new system makes the app too complicated. I want this program to be as simple to use as possible; so we should revert the "Policy" system to essentially what it was in the last major version. The only change I want to make is [...] and everything else is essentially the same as the last Policy system."
So basically he wanted us to FUCKING UNDO EVERYTHING WE HAD DONE AND REVERT THE FUCKING PROGRAM TO THE FUCKING VERSION HE HAD BEFORE HIRING US!!!! WHAT THE FUCK????
YOU WANTED US TO CHANGE YOUR APP AND THEN YOU SUDDENLY CHANGE YOUR MIND AFTER 3 FUCKING MONTHS WHEN THE PROCESS IS DONE???

Hello everyone 👋
I see people blaming the developers when you see a crappy software product , saying that they have done a bad job.
But even it could be true also it could be the product managers who didn’t give enough time todo what needs to be done or project scope is too big for the persons knowledge.
I’ve worked in a company where deadlines were so tight I didn’t have enough time to proper UI and Testing. I used to be only developer who has someone experience and I had to train the interns as well. I am also to blame to joining such company but in desperate times takes desperate measures.
And now when i’m leaving the company and I have spend 2 years of my life for apps that I’m not proud of.
Just rant. Please feel free to give ur thoughts2 -

In my country, almost every college student is expected to finish their degree and apply for an internship, with some universities forcing them to do it and making it a requirement to finish their studies.
Now, this wouldn't be so bad if almost every internship employer in the country didn't expect you to work for free. Seriously, I can estimate 80% of the internships pay you NOTHING. WTF.
Fortunately this is not the case for CS, but every time I tell somebody I recently started an internship, they will ask me: "Oh, but they don't pay you anything, do they?". Of course they pay me! I wouldn't be going to an office every day for 4 hours to do someone else's work if they didn't!!
Why the fuck is it even legal to employ somebody and not pay them a cent, just because "it will look good on your resume"?? And why do people still accept this shit??
Is is like that on other countries as well?2 -

A lot of larger companies seem to be a happy about forcing employees to change their password every three months or so. They do it for security measures so that it is more difficult to break through the system, however most people end up making the worst passwords.
Instead of forcing a very good password on them every year or two maybe, they all end up having passwords like: "Summer16", "Qwer1234", "London15".

Getting back into my Lego robotics. Going to be pretty exciting! With the nxt having Bluetooth I could potentially hook it up to my Raspberry pi and have the pi behave as a base station to relay commands based on sensory input from the nxt "rovers".
Obviously this generic kit design is good for testing, but may need improvements to work as more durable rovers. Somewhat similar to the classic rcx2.0 rover pictured.

A while ago, i decided to finally learn a bit about the web stack (especially django) and create my first web page. The image shows what it currently looks like.
I am actually very happy with the result. It will be my personal little Home automation software, with progressive apps etc. It runs on the pi plattform and can currently switch an IO to a Relais, which in turn switches on a light.
The applications of this are really endless, which is quite cool and leads me to do more stuff at my home with it. So dear devRant: Does anybody know of some nice hackable light bulbs/spots for my home that i can use? Or other cool hackable hardware that could be applied?

Pro tip: always make sure your methods return the correct variable.
I’m currently working with deep neural networks using tensorflow. I needed to generate some test data and wrote a program to create it. I had two text files which each consisted of approximately 5000 lines of text.
I wrote a method that should sort out some words, and make my final data shorter. When I executed the program first time on our server, it spent about 25 minutes, then crashed due to MemoryError (which in Python means that the server didn’t have enough ram). That seemed quite weird since I only had about 10k lines of text, and I even sorted out a bunch of it, and the server has 128gb ram, and nothing’s using it.
Apparently I returned the wrong variable. That meant that my program tried to save 750 quadrillion lines of text rather than just a few thousand.
Always make sure to return the correct variables!1 -

My most humbling experience was finding the source code online to the original Pokemon games. It was right after I had finished my first text based Linux console game and I was looking up other programs source codes just for shits and giggles. Most of them were simple and I learned a few simple tricks but the red and blue Pokemon were the first codes I saw that fascinated me. The addressing, the memory allocation, even the simple audio processing was simply genius. So many unique innovations and techniques. If I achieve 1/5th of the skill I found in those files, I can die a happy programmer!3

And I would be ok with that... but how the fuck do you carry on with your social life. At some stage you're bound to say to your guests:
"Hey guys, listen to this tune" after which you pass them the salt dispenser.

Just set up my own IoT device for free thanks to the guys at Losant.
I met them at codestock a couple years ago. They were running a workshop with some Adafruit boards and at the time I had never seen anything like Arduinos before. I was fascinated. So I walked up and asked about it. They said they sold the chips just to demo their IoT stuff. I said I'd buy one. I then waited like 40 minutes for them to get their card reader working. They gave up and handed it to me, gratis. That started my dive into electronics from programming.
Few years later, I needed a remote temperature sensor to make sure a certain unattended appliance never got below freezing. I suddenly remembered that kit (now buried under my heaping stash of electronics), followed the tutorials, and had the exact thing I needed up and running in like a few hours, with all the bells and whistles I could want. And for free.
The icing on the cake here? I went on their website to look at a kit to replace it. I found one with even more goodies in it, and the entire kit cost less than the cost to go to adafruit and buy just the board alone.
Thanks Losant for being awesome. If you wanna do IoT anything, look em up. -
Do you need a degree to become a software engineer ?
Now this is a question I’ve seen many people ask. I personally have no degree and I’ve been doing programming for the past 10 years (since I was 18 ). Whatever I learned, I learned from reading and watching tutorials.
So far It wasn’t a problem for me.

Just created my own publish-subscribe-based IoT protocol for the NodeMCU. It's like a simplified version of MQTT and pretty error-rich. (So it shouldn't be used in important cases). But the cool thing is that you can use a simple NodeMCU to host a server and don't need to set up a Mosquitto Server on a Linux Machine.
Will release on GitHub soon!

Avoided IoT(IoS - InternetOfShit) for a long time now, due to the security concerns with retail products.
Now I looked into 433 Transceiver + Arduino solutions.. to build something myself, just for the lolz.
Theory:
Smallest Arduino I found has 32 KByte of programmable memory, a tiny tiny crypto library could take around 4 KBytes...
Set a symetric crypto key for each homebrewn device / sensor / etc, send the info and commands (with time of day as salt for example) encrypted between Server <-> IoT gadget, ciphertext would have checksum appended, magic and ciphertext length prepended.
Result:
Be safe from possible drive-by attacks, still have a somewhat reliable communication?!
Ofc passionate hackers would be still able to crack it, no doubt.

Guys, I need some advice.
A couple of weeks ago I finished my internship as a sys admin in this medium sized consulting company. When my "contract" was about to expire they offered me a real job doing the same thing I've been doing for the past few months, but I turned it down.
The reason why I did it was that I wasn't really happy with the job. I mean, the people were... fine, the management team was... fine, the actual work I needed to do was... fine. I think you get the idea. The problem was that I never really enjoyed it all that much, and even though I didn't hate it, I wasn't really happy with it, so I turned the offer down.
After giving it more thought and listening to what some of my friends and family members had to say, I started thinking that maybe it was a bad idea to do so. Many people have said to me that I'm making a mistake, that I shouldn't leave a job before I have a new one, and that I should take the offer, work there for a little while and then look for something else.
I always answer by saying that the job market in this field is much more simple, and that it's much easier to find a new job than in any other, but yet again, I'm not sure if I'm making a big mistake with this decision.
Thoughts?
PS: I'm 21, this would be my first job ever7 -

TL;DR: Have you ever been on a serious company where you have to DRAW a high fidelity mockup of the software in the design phase?
So I'm in my last year of college and I have a class called Interactive systems design, which is basically about usability and how to design the frontend of your app so it's intuitive, pretty and easy to use.
So we work in groups to design a project for the entire semester, following a long and tedious process of research and planning which includes writing absurdly long documents, doing interviews with potential users and more.
Now that we've done all of that, the teacher insists that we make paper mockups of our app before we do a digital one using Balsamiq or other programs. He wants the paper mockups to be "interactive", so we have to draw them and then record a video where someone "clicks" on the mockup with their fingers and another person moves the papers around to make it look like an actual app that's doing something.
The teacher still insists this is something almost every company does when designing a project, so it's very important that we learn to do this kind of stuff. He's kidding, right? Have you guys ever drawn a mockup of an app instead of using some mockup software?7 -

I just got an old refurb for the garage to run my camera capture stuff, as the raspberry pi wasn't cutting it. I thought for a split second about leaving the legit version of Windows 10 that came with it on it, and trying to do some in-home streaming over steam, but I found out very quickly that an old corporate refurb is not going to cut it for game streaming. And with all the complete nonsense you have to abide to make Windows usable(ie: disabling stuff you don't want), it's not going to be any use to me in Windows if it can't stream.
Also, for some reason, Windows just wouldn't use the built-in NIC at all. It reported the cable was unplugged, and just absolutely would not work. So, Debian it is, and lo and behold! The NIC works like a champ now. The camera capture works brilliantly too, so now I can turn off my desktop at night.
Linux just works. Windows, more and more all the time, is just more trouble than it's worth.2 -

The fucking nail to my coffin. This thing is so unreliable. I fixed on issue get the next one. Then get an error trying to make a http request, with little information on the web. Eventually switch to FTP which is working for a while. Then suddenly nothing is working properly. Even the serial communication has errors. This process took over 6 months. Constant debugging and headscraching involved. After hundreds of hours I give up. I'm going to switch to a Raspberry Pi Zero with an UMTS Stick attached. This is going to cost way more battery time but my project needs to be finished by july and I'm tired of this shitty little module.2 -
Nice. I have now wasted about 8 hours or so debugging to find out why my (fully functional) program wouldn't receive messages (from an FTP server through a socket). It just received an timeout from the server after 300 seconds. Then I discovered that my messages didn't include '\r\n' in the end.

MQTT - all I used to know about this is its name, untill few months back a client sent us some requirements which included MQTT. I opened its specification and I was fucking shocked! I am implementing almost similar protocol in most of my applications (which needs subscription based service) for last 3 years. I have developed IoT apps, remote monitoring systems, HMI systems using the same fucking protocol! Even I had implemented the same thing on HTTP using long polling a few years back!!
Now I feel like open sourcing my protocol. But I don't know where to start. Any help please?1 -

I am a young dev trying my hands around in different stuff.
So I would appreciate any criticism or comments that would allow me to Learn more :) or good practices I can follow.
Here is one project where I tried to create a structured frameworkish way to write mqtt processors.
Mqtt processors are standalone apps that process mqtt requests that has to be acted upon (like add sensor data to db sent from sensor node, read from db, turn some gpio on or off if the app is on some embedded device like raspi ) etc.
This project creates a structure where you can just focus on writing subscribed topic listeners in a clean neat way. (Hopefully)6 -

I had to contact my ISP's tech support because I suddenly lost my Internet connection. I explained to the guy who answered that my router was working fine, and that my devices could connect to my WiFi network, but they didn't have Internet access.

I just got hired at a small MSP and I’m just utterly fucking frustrated by the shitty tools and complete lack of client documentation. I want to implement tons of FOSS tools for these newbhats but they seem to like spending money on tools that only work half-assedly at best... looking at you LogMeIn!
I’ve setup Apache Guacamole a few times before and want to get each client a guac-srv setup for client’s server mgmt. or PowerShell Web Access for clients.
I want to build AWS infrastructure for clients cause we can use cloudformation or terraform to build infrastructure. But these skunk-taint licking dipsticks would rather support physical 2003 servers. If I didn’t need this job to pay my bills right now I’d be fucking gone.
But... they are very nice people.

(a bit late for wk73 but I wanted to post this anyway)
Back in my first year of university, we had to write a relatively simple (though it looked super complicated back then) C++ console application. I don't know what it's called, but it's that game where the computer generates a random 4 digit code and you have to try to guess what it is. Every time you try, it will tell you which digits are correct, which would be correct if they were in a different position and which are outright wrong.
Anyway, the program had a main menu with a help option that would output a short guide on how to play the game. Instead of hard coding it into the source code, the "guide" had go be written in a separate text file and then read and dumped to the screen when necessary.
Here came my great idea on how to read files. Instead of looping through the file until I reached the end, I counted the number of lines my text file had and wrote some gem of a piece of code like this:
for (int i = 0; i<11; i++){
line = file.readline();
cout << line << endl;
}
My teacher obviously took points off for doing such a stupid thing, and I remember complaining A LOT about it. I argued that 11 was a constant because I didn't plan on changing the text file, and that the teacher had no right to take points off for only reading 11 lines because the file only had 11 lines, so it was read in full.
Goddammit, what an innocent little brat I was. I'm glad my first programming teachers were good enough to stay firm and teach me how to do things the right way, even if it's the hard way. -

I was trying to set up my own "cloud" for iot experiments. I planned to use Intel Edison with mqtt broker (using mosca) and a node js app for providing API for mobiles and browser. And also to do other book keeping.
I spent the half day trying figure how to expose these servers to internet.
I configured ddns in noip.com and ddns settings configured to it in my router.
Port forwarded to the local server services I needed.
And then tested. Worked perfectly on any device in my router connected network. Tested on mobile network. Bam! It fucking doesn't work.
Then connected another router.
Double port forwarded. Again worked perfectly on router network. And failed on mobile.
Tested if ddns is right. Did nslookup it was fine as fuck.
Then disabled port forwarding. Did dmz. Nope. Nadda. No luck.
Then scratched my head so hard that I lost more already losing hairs.
Then remembered about router hardware firewall. Disabled it.
Tested
And there it didn't work.
My dreams shattered like a fucking deer hit by car on highway.
Didn't work.
Then I see the IP pointing to my router in nslookup. Its 172.20.xx.xx. Its a fucking private IP.
My Asshole ISP is running another private network behind firewall. Which I fucking can't port forward
Now I think how much of a noob and idiot I am. Fuck this shit. Fuck all of these shit.

After years of using an android wear on a regular basis I've gotten used to it, I use pujie black for a simplistic watch face and love it, I answer calls on it (although it doesn't have a speaker), and reading texts has been a lifesaver at times. I initially had an issue with the battery life but that was probably my fault for creating a really animation heavy watch face on watchmaker. Anyways while I love the thing it's really excessive (i know original argument huh?), I would love a smart band that can do all the simple things ( tell time make calls and display/read notifications ) and some awesome IoT remote functionality. After some research I found the nex band (I had actually seen this band often prior on Amazon but always just skipped over it cause I assumed that it was a fitness tracker, lesson learned again, don't assume). It looked promising, unfortunately it lacked a few key points that are essential to me. It was missing the most obvious thing, a clock, the band is split up into 4-5 rgb displays so there isn't much room for a clock. Second there is a proprietary clip on micro usb adapter (Ughhhhhh). Finally it it looks too niche and bulky. I'm keeping an eye on it cause i would love it if they at least fixed the clock and appearance issue as I don't travel much so the adapter would just sit on my nightstand anyways. Does anyone know of anything similar to the nex, everytime I search anywhere I get nothing but fitness or motion trackers.
