THIS is why unit testing is important, I often see newbs scour at the idea of debugging or testing:
My high school cs project, i made a 2d game in c++. A generic top down tank game. Being my FIRST project and knowing nothing about debugging or testing and just straight up kept at it for 3 months. Used everything c++ and OOP had to offer, thinking "It works now, sure will work later"
Fast forward evaluation day i had over 5k lines of code here, and not a day of testing; ALL the bugs thought to themselves- "YOU KNOW WHAT LETS GUT THIS KID "
Now I did see some minor infractions several times but nothing too serious to make me refactor my code. But here goes
I started my game on a different system, with a low end processor about 1/4 the power of mine( fair assumption). The game crashed in loading screen. Okay lets do that again. Finally starts and tanks are going off screen, dead tanks are not being de-spawned and ended up crashing game again. Wow okay again! Backround image didn't load, can only see black background. Again! Crashed when i used a special ability. Went on for some time and i gave up.
Prof saw the pain, he'd probably seen dis shit a million times, saw all the hard work and i got a good grade anyways. But god that was embarrassing, entire class saw that and I cringe at the thought of it.
I never looked at testing the same way again.6
What is the most ridiculous over-the-top "startup" thing you've been the victim of as a developer?
Alternatively, what kind of weird startup luxury would you absolutely love to have at your company?
For me, at various companies I've worked at/visited:
1. Hammocks & fatboy beanbags. Current employer has a "Netflix & Chill" corner with nice couches, and a small gym. I have encountered isolation/flotation tanks at the office of one of our partners... which is cool, but over the top in my opinion.
2. A fully automated aquaponics garden in the lunchroom. Was awesome, until some fish died and started to rot.
3. One hoverboard per employee, at previous employer. I splashed hot chocolate milk in an arc over three desks. A coworker broke his ankle while watching me spill chocolate milk.
4. Daily scrum standup meetings, on socks, in a big bouncy castle. Not kidding. Fucking ridiculous... (but secretly fun). That employer also had spiral slides between all floors, a tiny half-pipe with tiny skateboards, and someone who rode a unicycle way too much. It was a fucking circus. Stuck in the office of a Fintech company.
5. Soldering bench (at my current company), with drawers full of breadboards, servos and electronics components. Completely unrelated to my work, but it was my idea. It's just great to build a simple kits together with another random coworker while brainstorming platform features & refining specs... much better than meetings with bullshit slides.
6. Unlimited energy drink. Developed a serious caffeine habit (15-20 cans a day), and almost got a stomach ulcer. Not beneficial to employee health.
7. I really do love working from home + unlimited holidays. Just being able to honestly say "fuck you guys, I'm gonna get drunk and play games today", and at other times working until 4am and sleeping in the next day, or taking a week to work in a park in Rome... It makes work truly feel like my favorite hobby. Combined with a good sprints and curious/ambitious people, you can easily track productivity anyway.19
I have this little hobby project going on for a while now, and I thought it's worth sharing. Now at first blush this might seem like just another screenshot with neofetch.. but this thing has quite the story to tell. This laptop is no less than 17 years old.
So, a Compaq nx7010, a business laptop from 2004. It has had plenty of software and hardware mods alike. Let's start with the software.
It's running run-off-the-mill Debian 9, with a custom kernel. The reason why it's running that version of Debian is because of bugs in the network driver (ipw2200) in Debian 10, causing it to disconnect after a day or so. Less of an issue in Debian 9, and seemingly fixed by upgrading the kernel to a custom one. And the kernel is actually one of the things where you can save heaps of space when you do it yourself. The kernel package itself is 8.4MB for this one. The headers are 7.4MB. The stock kernels on the other hand (4.19 at downstream revisions 9, 10 and 13) took up a whole GB of space combined. That is how much I've been able to remove, even from headless systems. The stock kernels are incredibly bloated for what they are.
Other than that, most of the data storage is done through NFS over WiFi, which is actually faster than what is inside this laptop (a CF card which I will get to later).
Now let's talk hardware. And at age 17, you can imagine that it has seen quite a bit of maintenance there. The easiest mod is probably the flash mod. These old laptops use IDE for storage rather than SATA. Now the nice thing about IDE is that it actually lives on to this very day, in CF cards. The pinout is exactly the same. So you can use passive IDE-CF adapters and plug in a CF card. Easy!
The next thing I want to talk about is the battery. And um.. why that one is a bad idea to mod. Finding replacements for such old hardware.. good luck with that. So your other option is something called recelling, where you disassemble the battery and, well, replace the cells. The problem is that those battery packs are built like tanks and the disassembly will likely result in a broken battery housing (which you'll still need). Also the controllers inside those battery packs are either too smart or too stupid to play nicely with new cells. On that laptop at least, the new cells still had a perceived capacity of the old ones, while obviously the voltage on the cells themselves didn't change at all. The laptop thought the batteries were done for, despite still being chock full of juice. Then I tried to recalibrate them in the BIOS and fried the battery controller. Do not try to recell the battery, unless you have a spare already. The controllers and battery housings are complete and utter dogshit.
Next up is the display backlight. Originally this laptop used to use a CCFL backlight, which is a tiny tube that is driven at around 2000 volts. To its controller go either 7, 6, 4 or 3 wires, which are all related and I will get to. Signs of it dying are redshift, and eventually it going out until you close the lid and open it up again. The reason for it is that the voltage required to keep that CCFL "excited" rises over time, beyond what the controller can do.
So, 7-pin configuration is 2x VCC (12V), 2x enable (on or off), 1x adjust (analog brightness), and 2x ground. 6-pin gets rid of 1 enable line. Those are the configurations you'll find in CCFL. Then came LED lighting which required much less power to run. So the 4-pin configuration gets rid of a VCC and a ground line. And finally you have the 3-pin configuration which gets rid of the adjust line, and you can just short it to the enable line.
There are some other mods but I'm running out of characters. Why am I telling you all this? The reason is that this laptop doesn't feel any different to use than the ThinkPad x220 and IdeaPad Y700 I have on my desk (with 6c12t, 32G of RAM, ~1TB of SSDs and 2TB HDDs). A hefty setup compared to a very dated one, yet they feel the same. It can do web browsing, I can chat on Telegram with it, and I can do programming on it. So, if you're looking for a hobby project, maybe some kind of restrictions on your hardware to spark that creativity that makes code better, I can highly recommend it. I think I'm almost done with this project, and it was heaps of fun :D13
Just turned 21 last month, today this arrives in my mailbox
Tanks for one of the best birthday gifts i wished for!!9
Today I remembered why I don’t “wing” things.
Anyway, here’s my cat in a cardboard tank.
Make two of everything. So when one project tanks you can pick up the pieces and improve the second project.5
Hey Guys :)
I'm new to devRant and I already read a lot of interesting stories and jokes and now I would like to post the first thing myself. :D
I would like to present you my new Android app "WhatsBirthday", which I made in order to solve a big problem of mine, friends (and probably the whole world xD). I have (as a Google User) all my contacts (with their birthdays) in the cloud and from there on my calendar. Sadly the Google calendar doesn't allow notifications for the contacts birthdays (I mean whyyy?!). And even if I take a look at my calendar, I always have to write these annoying birthday WhatsApp message to the people ... and these both were the problems I wanted to solve with my app.
So if you join the app, it will start a service (an Alarm / Alarmmanager for the professionals) which will take a look at the contacts every day at 6 am (can be set in the app). For each contact whose birthday is today, the application will send a push notification which if clicked will directly open the contacts WhatsApp chat and prepare a standard message with the name filled in, which could (in theory) directly send. For sure the app won't sends any messages by itself, but it gives you a template you can start working with.
And for sure, you can edit the template in the app & specify the messages for family and friends, which you can choose to use with the notification buttons.
So yeah, that's is and I hope I've aroused your interest ;) if you would like to download it: https://play.google.com/store/apps/...
I would be super happy if you could give me some feedback, it's one of my first apps and I would definitely like to improve it! Tanks in previous! :D
And I would like to say sorry for my bad English skills, I'm a German student :O if the translations in the app are not good, please tell me! ;)28
Yesterday I bought myself a PSP to relive some of my childhood memories, run custom firmware on it and so on. Unfortunately however, the battery on this one is seriously puffed up, and I need one in order to update the firmware from 5.50 CFW (the seller actually modded it too!) to 6.61 OFW (to then install CFW from there again).
I figured that I might as well have a kick at disassembling the battery for good measure, to take out its controller and power it from my lab bench power supply. I set it to 3.70V, double-checked the connections.. nothing. I raised the voltage to 4V, still nothing.
There is absolutely nothing wrong with the controller from looking at it. The magic smoke is still in there, all I did was removing the housing and snipping off the battery. I measured the cell voltage and it was only some residues at 0.01V. Might be internally shorted or something, normally even dead cells settle back at 3.7V unless you keep them shorted externally.
After seeing this so many times now with controllers, I'm starting to get a feeling that manufacturers actually program these things to look at the battery voltage, and when it reaches 0V, to just make the controller kill itself. Doesn't matter if the controller's electronics are still good, just fucking kill it.
If true, that is very, VERY nasty. It would also explain why batteries in laptops especially all have different form factors, despite having used regular 18650's internally for a very long time. It would explain why they're built like tanks. It would explain why manufacturers really don't want people in there. Yes there are safety issues and you're literally diffusing a bomb. Since recently we've also got space optimization.. anything for half a mm of thickness, amirite? But doing it this way is fucking disgusting. There is absolutely no reason for the controller to kill itself when the cell dies. Yet it seems like it does.
PS: I've posted the original picture on https://ghnou.su/pics/... now if you're interested. I noticed in my previous rant that devRant really squishes these down.12
Elon musk starts new companies like I start new projects.
I like that he's doing AI research, but it's annoying that the day after he tweets something, everybody's telling me that Elon Musk already invented true AI.
These companies are basically just think tanks, so why not call them that?4
Went to a GDD Extended event for the first time. All they told was

During one of our visits at Konza City, Machakos county in Kenya, my team and I encountered a big problem accessing to viable water. Most times we enquired for water, we were handed a bottle of bought water. This for a day or few days would be affordable for some, but for a lifetime of a middle income person, it will be way too much expensive. Of ten people we encountered 8 complained of a proper mechanism to access to viable water. This to us was a very demanding problem, that needed to be sorted out immediately. Majority of the people were unable to conduct income generating activities such as farming because of the nature of the kind of water and its scarcity as well.
Such a scenario demands for an immediate way to solve this problem. Various ways have been put into practice to ensure sustainability of water conservation and management. However most of them have been futile on the aspect of sustainability. As part of our research we also considered to check out of the formal mechanisms put in place to ensure proper acquisition of water, and one of them we saw was tree planting, which was not sustainable at all, also some few piped water was being transported very long distances from the destinations, this however did not solve the immediate needs of the people.We found out that the area has a large body mass of salty water which was not viable for them to conduct any constructive activity. This was hint enough to help us find a way to curb this demanding challenge. Presence of salty water was the first step of our solution.
We came up with an IOT based system to help curb this problem. Our system entails purification of the salty water through electrolysis, the device is places at an area where the body mass of water is located, it drills for a suitable depth and allow the salty water to flow into it. Various sets of tanks and valves are situated next to it, these tanks acts as to contain the salty water temporarily. A high power source is then connected to each tank, this enable the separation of Chlorine ions from Hydrogen Ions by electrolysis through electrolysis, salt is then separated and allowed to flow from the lower chamber of the tanks, allowing clean water to from to the preceding tanks, the preceding tanks contains various chemicals to remove any remaining impurities. The whole entire process is managed by the action of sensors. Water alkalinity, turbidity and ph are monitored and relayed onto a mobile phone, this then follows a predictive analysis of the data history stored then makes up a decision to increase flow of water in the valves or to decrease its flow. This being a hot prone area, we opted to maximize harnessing of power through solar power, this power availability is almost perfect to provide us with at least 440V constant supply to facilitate faster electrolysis of the salty water.
Being a drought prone area, it was key that the outlet water should be cold and comfortable for consumers to use, so we also coupled our output chamber with cooling tanks, these tanks are managed via our mobile application, the information relayed from it in terms of temperature and humidity are sent to it. This information is key in helping us produce water at optimum states, enabling us to fully manage supply and input of the water from the water bodies.
By the use of natural language processing, we are able to automatically control flow and feeing of the valves to and fro using Voice, one could say “The output water is too hot”, and the system would respond by increasing the speed of the fans and making the tanks provide very cold water. Additional to this system, we have prepared short video tutorials and documents enlighting people on how to conserve water and maintain the optimum state of the green economy.
IBM/OPEN SOURCE TECHNOLOGIES
For a start, we have implemented our project using esp8266 microcontrollers, sensors, transducers and low payload containers to demonstrate our project. Previously we have used Google’s firebase cloud platform to ensure realtimeness of data to-and-fro relay to the mobile. This has proven workable for most cases, whether on a small scale or large scale, however we meet challenges such as change in the fingerprint keys that renders our device not workable, we intend to overcome this problem by moving to IBM bluemix platform.
We use C++ Programming language for our microcontrollers and sensor communication, in some cases we use Python programming language to process neuro-networks for our microcontrollers.
Any feedback conserning this project please?9
Took a college class - think it was called "Programming for Designers" - and the "teacher," aka CS grad student, just sat and played Pocket Tanks the whole time.
I have already started the process of a side project by desiging the software, the architecture, the 3d model, ordered all the electronics of a pet 'smart' stable for my guinea pigs.
Which would automatically feed them and refill their water tanks silently but for me the point on playing around with dozens of sensors for like different water levels, water quality, hay, temperature, water quality (you get the point) ... Building a nice looking web interface or an App to control everything and get a live feed from different angles ( sounds a bit crazy altogether but it looked like a cool project )
I even started a instructable and had a github repo for sharing the source of the app/web interface and the whole micro service based server
I'm still at it and hopefully will start to build the ***ing wood and acrylic parts in the next month's but currently and for the last month's free time ist my archenemy
Keep you posted if you are interested 😀
Computer does a BSOD right at the end of a tiebreaker competitive overwatch match where the enemy is about to cap the point and win. I'm one of the tanks. Hard reboot and back in the game within 45s. Just barely hold them off in overtime and win the match. Epic!
Thank God for SSDs!4
Finally did it!
Replaced my desktop pc (which I use for gaming) which had Windows 7 with Arch Linux! It was not hard because I already use it on my laptop.
OK it was a bit struggle with nvidia and cinnamon due to missing libraries I had to install which I don't know before.
But it is possible to play games on Arch?
CS:GO - works (native, steam)
League of Legends - works (wine)
World of Tanks - works (wine)
All I need is working (:2
Non-programming related rant:
I didn't have a profile picture of facebook. So, I put one & removed the update post from timeline.
Still getting likes.
I don't want them *fb.5
A game where you build creatures from muscles, tendons, bones, blood vessels, other fluid containment and transport organs, as well as nerves and brains. Probably would look very gross. Gore-centric game.
Similarly, a game where you build robots out of Pistons, gears, Axels, fluid tanks and hoses, engines, sensors, computers and wires.
Either one of these premises is pretty amenable to a backstory where you're trying to escape-from/survive-on an alien world.
Friend keeps gold coin in case the economy tanks. I have a home git server in case the Internet goes down.1
In World of Tanks if you dont play well then your mates tell go and play tetris...
But we all know that the programers are smarter and if you dont write code well then they your friends will telln go and play a GAME..
LETS SEE WHO GETS IT.
