Testing a raspberry pi 4 as a computer driving our 4k dashboards' screen. Temperatures are constantly 80-90C.
Me: STEP ASIDE! MAKE WAY FOR A HOTFIX!
Rpi: aaahhh, 42C -- now we're talkin!

How has coding impacted your life...?
- Using Linux
- Valuing OpenSorce over cracked software
- Using more CLI than GUI programs
- Only playing games that run on Linux or Wine
- Hating Micro$oft
- Utilizing VMs and Servers
- Tinkering with Hardware (RPi, custom PC)
- ...
... Nah not that much. 🤗😅13 -
Got some new toys today! A Raspberry Pi 3 and a Arduino starter pack. Any suggestions on what I should do with it?

That feeling you get when you run
$ php tvVolUp.php
And the god damn tv’s volume goes up a level 😆
Now to clean the shit out of the chaotic mess I just made and make it work from a Rpi which I’ll then add to my voice activated list for my google home.
Coz you know voice activated TV remote in PHP 😍5 -
HAHA. Classmates were trying to change my wallpaper or something on my laptop. They didnt even boot to the damn system. LOL. First they didnt know how to launch from GRUB. Ater they figured that out they were hit by SSD + HDD encryption. No fucking way they are gonna guess 28 character long decryption key which was randomly generated by my own program.
Revenge you say ?
Well done already.
The guy who had the idea had a notebook too. Well i just turned on the PC and hey look at that. Offline account with no password.Well i changed his wallpaper to just simple text. "USE PASSWORDS"
Oh yes this was all in the limits of fun. Nobody wanted to do some crazy shit that could break our systems. We were just having fun. But hey i guess i won.
Oh and yes as the second part of the revenge i was sending deauth packets to his PC all the time with help of Rpi zero in my desk. Damn was he pissed when i told him at th end of school that it was me.6 -
Friend: what's that banana pi server that you bought
Me: it's a raspberry pi and I made it into a NAS
Friend: set it up so we can play COD Zombies
Me: .....

When your raspberry pi is bombarded with /phpmyadmin URL attempts in all its forms and possible paths and versions 😅
Like seriously? Who in there right mind uses phpmyadmin AND has it accessible to the public.
- there's no databases on this Rpi but you keep looking.11 -
Buses in Slovakia uses RPI 2 for they TVs apparently they don't manage it so good if they got Kernel panic.
The RPI loses power when bus turns off.
That's what you got bitches for shuting down RPI the dirty way(disconnecting the power source).

This is my desk right now, anyone else who really enjoys fiddling with arduino / rpi electronics stuff?
Like making a remote for the projectors in school or using an Ethernet switch and a raspberry pi to create a WiFi network :P

When you set an alias for vi and completely forget about it
# alias vi=nano
God damn, I was so confused for a minute 🤦♂️21 -
When im going home from school i spent about 45 minutes in a bus with free wifi.
Since im geek i always run checks on network that i enter. Well what a suprise. Slovakia fucking MHD (Buses) uses a device with linux 2.6.32 ffs. And Rpi with 4.4 or even less. Im seriusly thinking of running dirty cow script on that 2.6.32 device. This shit is just crazy.
Im waiting for my NFC reader to check the cards that we use to pay in the bus. Either it will just have the money stored on that card which i hope is not true. Or its just ID and server has the money in which case i can just buy NFC cards without manufacter block and just copy the card to that one and well have what ever card i want.
So if somebody is working at Slovakia MHD go and fucking secure your fucking crap ffs. Im not even talking about trains since those just use admin admin as login to router.6 -

Finally i can say total bye bye to Microsoft today i finally successfully installed ubunto on Lenovo miix 3 830 yayyyy on other PC and Rpi i have arch but i cant get arch to work here (i will try it) so i installed ubuntu yayyyyyy

Not really hacking, but my roommate says otherwise. So we share a router in the apartment and I’m the only one that really knows how to access it, so of course I change the password and tell no one (not like they’ll try to get in anyway).
Occasionally set roommate likes to get blackout and play music very loud at 2am. To be petty, on those occasions I set up an RPi Zero to connect to the WiFi, restart it, and sleep for a minute, and repeat. He’s still convinced we are getting DDOSd, and suspects nothing.
Reason I don’t just set parental controls - he gets more frustrated when the WiFi appears for 10secs, the music is just about to start and shuts off again. So he gives up quicker. Otherwise, he resets the router and I have to set up everything from the start.3 -
I have finally launched my own mirror. I would really appreciate if you guys that use Raspbian could start using my mirror so I can see if shit works :)

Sometimes I want to slap myself.
I’ve been making progress with my voice activated TV remote project - coz you got to use a Google Home and a Raspberry pi for something right? Right??
Anyway, when the API you have written suddenly stops working and you’ve spent hours trying to solve it, it is really soul crushing when you realise you’re using a class variable incorrectly
I’ll just go cry now, while I control my tv 😥😎
Class TVAPI{
Private $tvIP = “192.xxx”;
Private $args = $this->decodeArgs($_GET);
Function of tvVolume(){
exec(“python tvRemote.py {$tvIP} {$this->args}”);
}

I'm about to change my setup to run pihole on this new RPi Zero W. Hopefully it has enough power to handle it.

Building a web based recipe book for my mother in law.
My brother in law, sorced the hw (touch screen aio)
I build the website build in php symfony3.
Running on a rpi in the garage.
She loves it and keeps telling everyone about it every chance she gets.
Currently re writing it in Django (for fun)1 -
That moment you work out how to get Google Home to make webhook calls, setup a Rpi to accept incoming https requests, and can’t think of anything to actually make it do

First year at university, prepared to set up multiple electronics.
rPi, arduino Ethernet shield, laptop, and desktop.
Brand new netgear switch to satisfy my internet surfing needs....
After setting up my devices, I realized none of them have internet. Hm. The feed port on my switch wasn't blinking either. So I tell the front desk, and a short 7 days later the port is back on. Yay, problem solved.
One morning I arise to see the port dark and inactive. Furious I use my laptop to share an internet connection while my actual port is "broken".
Support ticket is reopened and this time I get an email saying the port was disabled due to a security issue.
Me: what's the issue?
IT: there was more than two devices connected to the port
(OnLy TwO dEvIcEs PeR port???)
Me: oh okay I will only connect two.
The next day the port is disabled, again.
Me: can you tell me why it was disabled?
IT: a switch was detected being used, security error.
Me: how do I connect more than one device to the port without a switch???
IT: ...
IT: Please only connect one device.

So ive been messing around with my Google Home.. because having a voice activated weather station is cool and all, but as a developer it needs to be useful no?... and Raspberry Pi, cause you know, we cool kids have those sitting around doing nothing useful.
But back on track, getting these two to actually work together, and that almighty moment you can say "Hey Google, Deploy Project -X- to the Pi" and the Rpi just kicks into gear and pulls down the latest master branch from Gitlab for the correct project is mind boggling.
No more ssh + sudo git pull !!!
Disclaimer: i didn't pay for that Google Home, but its in my house, listening to my TV, so i may as well use the damn thing.2 -
I have done crazy stuff before but this time im going to take it to another level.
I compiled custom ROM on PC, Server, tablet, Rpi.
But this time lets take it to another level. Lets compile Android on Android.
Ouuuu yeahhh2 -
Ordered a Raspberry pi.
Excited to work on it.
Also ordered heat sink with it so as to make it 24/7
Till now I've thought to use as a cached DNS server+VPN client [and from it I'll share the incoming college WiFi to LAN (yes my college is finally getting WiFi for us in hostels)]+mopidy server with iris client
Give some more ideas.
Also, will the RPi be aple to work 24/7 without burning up if heat sink is installed?24 -
I didnt know what to do for christmass decorations.
So i created 8x8 LED matrix and spent my entire day coding this thing to display any fucking character i give it. Also connected it to Raspberry Pi so that i dont have to reprogram it to say something different. I just use my app and it sends signal to Rpi and then to arduino.
Yes im just bored and i had to create something.10 -
3 weeks of search, but now, I have a miniUPS with solar and dc input for my raspberry pi Zero with cam.
I have developed a little ble4 iOS app to monitor all voltages and relay states.
All this shit from China, about 50$ except rpi and cam.
What you think?

Why am I such an average ?
It's just a sad realisation. Nobody cares but I wanna send this out there, just to write thoughts.. I am 18 in 3rd year of high school (grammar school so nothing IT related, basically waste of time) and in IT I'm all self taught but I feel like I could be better if I just didn't [something]..
I feel like I wanna learn so many things but when I look at you, it seems like a common problem in the IT sphere so hey, average guy joining the club.
I also feel dumb when programming. I didn't manage to learn C++ in it's entirety because to really accomplish something, you've got so many ways to do it and finding the best one requires deep understanding of the tools you've got at your disposal with the language and I feel like I'm not capable of this(self learn, in school/Uni that's different story).. But many (most) of you are. I've tried many coding challenges and when I got it working, I just saw how someone did it in one line just by layering functions that I've never heard of..
Also, we've got kinda specific national competition here in many fields including IT for high schools.. And the winners always do sometimes like "AI driven Life simulation" or "Self flying drone made from ATMega from scratch with 3D simulation in C# to it" or "Game engine" or whatever shit and it's always from grammar schools and never IT related schools.. They are like me. Maybe someone helped them, I don't know, but they are just so far away from me while I'm here struggling to get the basic level of math for any kind of machine learning..
Yeah I've written Neural Network from scratch in C but meh, honestly it's pretty basic stuff .. I'd rather understand derivatives which we're going to learn next year and I'm too lazy to learn it from khan academy because I always learn something else.. Like processing (actually codetrain started teaching tensorflow so that might be the light for me...) Or VHDL (guys you can create your own chip / CPU from scratch and it's not even hard and OMFG it's so fucking cool , full adder done yay) or RPi or commodore 64 assembly or game development with Godot and just meh..
I mean, this sounds exactly like not knowing what to do and doing nothing in the end. That was me like 6-12 months ago. Now I'm managing to pick 2-3 things and focus them and actually feel the progress.
But I lost track of the original point.. I didn't do anything special, every time I'm programming something, everyone does it better and I feel dumb. I will probably never do anything special, everyone around says "He's still learning he's genius" but they have no idea.
I mean, have you seen one of the newest videos on Google's YouTube channel (I openly hate them, but I will keep that away for now), something like "Sarah story" ? It's about girl that apparently didn't care about IT but self learned tensorflow on high school. I think it may be bullshit (like ALL of their videos ) but it's probably just fancied, not complete lie.
And again, here I am. I now C but I'm incapable of learning to program good which most of you did and are now doing for living. I'm incapable to do anything cool, just understanding what everybody else did and replicating it. I'm incapable of being clever.
Sorry, just misusing devrant to vent a bit17 -
If you didn't think NodeJS dependency hell was that bad, you should try sequentially parsing a graph that's stored as an array of nodes and their references, where processing of said nodes forces you to use some async functions that depend on other async functions.
What should have been 20 lines of code written in 30 minutes has turned into 3 hours of horror, reading about babel, realizing that it's just adding more problems without solving one, assessing the effort of modification of async libraries to include sync methods as well, trying out asyncwait, async, and everything else there is, trying to rethink the recursive algorithm, rewriting it several times, cursing and hating myself for not choosing to use Python or .NET Core, screaming senselessly at my wife in a language as familiar to her as Klingon, crying in the bathroom, re-assessing my life choices, thinking whether it was a mistake to dedicate 10 years to this career, maybe I'm just not cut out for it since I can't handle this simple task, watching noose tying tutorials on youtube, thinking about my naked empty RPI that won't connect to the server any time soon.
Seriously. Why is it SO BAD?! Or is it just me?5 -
Remember that mechanical calculator I bought a couple of days ago? I cleaned and oiled it and it works. I might have a batshit crazy idea what to do with it.
I recently bought a so called Atomic Pi (a ridiculously cheap RPi clone with an Intel atom processor, check out their kickstarter campaign), and I am thinking about hooking it up to the calculator in order to automate it with motors and stuff. Perhaps I'll even add a Webcam and play around with image recognition in order to read the results. How cool would that be?5 -

RPi 4 is hard to get your hands on it seems.
Really debating buying it though, 4 GB is enticing, but I just don't see a place for it. I have a surplus of machines which are much more powerful and accessible (Display ports - not mini HDMI)
And let's not forget the sub-2GHz clock speed. My desktop goes to 5, and my server isn't far behind. And my laptop isn't far behind that. And my other laptop isn't far behind that. But this new Pi would be far far behind that.
Not to mention the ARM architecture. There have been leaps and bounds made since the Pi first came out in terms of support for ARM (Most certainly fueled by the Android craze) but it still isn't x64, is it?
If I were 13 again and I didn't have all of the toys that I do now, I would be elated at the launch of the Pi 4. But as it stands, I don't see a use for it. Maybe nostalgia.23 -
I just have my Rpi set up to compile latest kernel from master every day. And i have my arch notebook set up to download the kernel from server and check the package name and compare and then if its newer then install it. Poor little Rpi. Still cant figure out how to build X86 on Rpi tho. Probably wont use Rpi for it and will just do it on server and host it there too.2

Hey there 👋
I am more or less throwing any burden (WhatsApp, Facebook, Google etc.) out of my life. Of course I will continue using the Google account for YouTube and some games that need it.
That's what it looks like right now:
Raspberry Pi 3B+
✅ webserver
- forum - complete (atm just for me)
- blog - no ideas and just installed october cms and nothing done yet
- nextcloud - complete and filled with my porn... eeh... data
✅ mailserver
(missing spamassassin, clam or sth. like this but it's working 😂)
✅ matrix-synapse
(as an additional alternative to messengers)
______________
Raspberry Pi 2
✅ catches dust
(any ideas?)
Of course, many more configurations and the like are necessary before everything is ready... but what then or what else is there?
At the moment I still use WhatsApp. Just wanna take time before sending everyone a message about changing the messenger and that it should be important for thinking about the own privacy, which alternatives there are bla...
Edit: For passwords I'm using Myki - didn't hear anything bad about it yet and it's very easy to use (Firefox add-on, Android app).
I love my passwords with 200 characters 😂
Maybe someone's knowing more about them?
Hope I didn't forget a thing... thanks in advance aaaaaaand... I'm gone. ☺23 -
Sort of follow up to: https://devrant.com/rants/1351833/...
Now I can turn on/off my PC over the Internet. A little hacky but it works like a charm.
I'm using an Arduino IDE compatible ESP-12E with on board WiFi and a homemade optocoupler (LED + photoresistor).
Hopefully more projects like these are coming 🤗

IDK i guess 3D printer but then im building something even more cool which i cant talk about right now due to school rules about this crap.

Why is chromecast so stupid?
So I'm on vacation, in another country, in a hotel. I took my chromecast and downloaded offline music to be able to use the TV for at least some entertainment.
Wifi is with login, chromecast doesn't support that. And it has isolation so I was prepared that it won't work through the hotel wifi. So I used another phone to create a Hotspot, but with no internet because roaming here is crazy expensive.
I thought that would work, but chromecast simply refuses to work if there is no internet access.
Why does it need internet if I'm streaming locally anyway?
So I temporarily activate data roaming, and hooray it works, so I quickly disconnect because I have no idea what this shit of a device will start sending to Google and how much I'm gonna pay for it. It works for 10 minutes then it crashes and needs internet again.
Most useless piece of crap I ever bought.
Should have brought my RPi instead but it's busy keeping my home alive and well while I'm gone. Should have ordered in bulk.13 -
Finally made good use of my RPi and setup pi-hole on it. After a painful 4hour long dist-upgrade and picking the right filters it is working like a charm. Why didn't I make this work earlier.
I've also wrote a little script which queries the api and displays different info on the AMOLED screen that was lying around unused for some time.
In case you are interested (from left to right and bottom), the traffic in the last 10 minutes with the max value on a graph, the most active clients query and blocked ratio as lines relative to the top one, and an overview of the total queries/ blocked queries and total clients.
At least I've finally spent a weekend useful not just playing games and watching anime.

Here it goes my second Rpi cluster 😎
Actually there are 3 Orange Pi PC, 1 Rpi3, 1 Rpi2 and an Odroid XU4.
I plan on using it as a workbench for many technologies.
For example DevStack, Ansible, Gluster, TahoeLAFS, Kubernetes, Docker Swarm and such.
Any additional suggestions?

There's a side project that I wanted to finish for some time now:
I built a pipboy (from Fallout 3) for a close friend - 3D printed and colored the parts, made a preliminary setup.
But to this day, it's still missing a power supply and all the proper wiring. (Jumper cables ARE not.)
Apart from that, I probably want to replace the RPi in there for a slimmer version.
Development is all done, implementation needed.1 -
Today I made some lights turn on and off with Gpio on my Rpi and some php, really happy and I'm going to work on it cause the landing site is really ugly. Would it be appropriate to add "mechanical engineer" and additional to web developer to my resume now? 😂😂1

What is something I can complete in a week (let's say 30-40 hours) as a newbie (I made an android app, played around with engines like unity and unreal here and there, tried some c#, and I always mess around with the linux command line, my RPi, etc etc)? I'll start working in a dual-studying job ('applied CS') in 2 weeks so I'll have enough learning-without-doing to do. I just want to learn something by doing something useful (e.g. a small android app that I can put ads in or sell, or maybe provide something for free that people like. I don't want to write my own engine( that'd take very long anyways) or make a compiler because I feel that'd be kind of useless and even though it'd probably be fun, I would lack initiative.5 -

I’m going to fly tomorrow and was wondering if I can bring my raspberry pi in my hand luggage. As known sometimes people in security checks are definitely not that awake and I don’t want my rPi in a garbage bin thinking it’s a bomb or something.
Otherwise I’ll just copy everything I need on a VM and go with it , but I wanted my sensors live ahah13 -

The best experience I had as a student was attending a few masters degree classes at a computational arts course, it was awesome being the only developer in the middle of a lot of art graduated students who were learning to code. Awesome exchange experience, final projects were art exhibitions with interactive art. We used Arduinos, Rpi, Openframeworks, Processing. I miss that and I still think that my dream job will look like that. -

Why does noone implement autoupdater, especialy on linux side? Is there a reason i dont get? Sure, most system stuff is better in apt, but if i install servers, i do not want to wait for these stupid linux release timings! If it were hard, id understand. But most of this is possible with something like GitHub API and 20 Minutes of time. I mean, yeah backwards compatibility and what not, but then handle that internaly.
Example: I use dnsmasq on a raspberry pi. RPI is running raspbian. Raspian is debian 8. Debian 8 has a version of dnsmasq with a pretty annoying bug, which prevents me from using dnssec, as i cant open any cloudflare pages. Why, o why isnt this updated at MY will? Then, if it isnt, why is it so impossible hard to compile this myself, no docs for that, no binaries, NOTHING? Dear server devs, please add atleast basic autoupdate functionality without having to rely on the base os.
Or, give me easily deployable binaries, if you cant write something integrated.12 -
And this is how it starts. I bought a Raspberry Pi 3 B+, quite some time ago. Plain board, just the board and a case. Why? Well, I have no idea. I always wanted one for some reason... and finally got one.
I got a good sd card for it, and flashed raspbian and... now what? What should I do with this?
*Looks up "Cool RPi projects"*
*Nah, I already have a NAS... No, wouldn't really use a media center... play games?*
*Well, let me just install sshd and come back to it later.*
Today, I run pi-hole, jekyll, node, gitd, a ton of other things that ends with d... I am even considering buying an extra one (maybe two).
Now I'm really afraid of what would happen if I give in to the urge of buying sensors and add-on boards.2 -

Anyone recalls my raspberry's hotfix for overheating problem?
Frankly I am considering it as a long-term solution. I currently have a proper rpi fan applied but it's just too freaking noisy! I thought my work lappy is noisy when at 90C. But this tiny rpi fan is just.. Painfully loud! Especially when rpi is suppised to be tiny and invisible.
Soo.. Yeah.. 3"" fan for an rpi it is!9 -

Farewell ads you will not be missed -
Bored at the office. Company is done for. I'm spending my last days here, doing nothing, waiting for my new position to start. There's only that much you can read on devRant, and SO MUCH MORE you could do writing code. But I just can't decide what to do and as a result sit here doing nothing. Help me out please! Answer with the most points will be the thing I'll start with on Monday, while today I think I'll just crack open a cold one.
My initial variants:
1. Learn Electron by playing with Electron React+Redux basic boilerplate, in order to make a simple personal blogging app.
2. Complete some of the 20 courses that I bought on Udemy 6 months ago.
3. Write the back-end logic for my Raspberry PI controlled systems at home (to control it remotely I'll make a hosted API that RPI will access to get input for it to decide what to do).
4. Solve problem 51 on projecteuler.net with an algorithm that runs less than 20 seconds.
Other suggestions are welcome.1 -
Is this normal for Raspbian installed with NOOBS for Rpi 3b+? The clock speed is correct, but ARM7 certainly isn't. Ri 3b+ certainly uses ARM8. Why does this happen?

To be honest the exact bug I don't remember. I do recall that it had something stupid I had been trying to fix to get nodejs working on a raspberry pi. I finally figured it out and managed to get a simple rest server going. After hours of trying to fix what might now seem insignificant, I was not only relieved that I got it working, but also thrilled that I kept at it and managed to fix it.

Do NEVER give Linux-Mashines similar hostnames!
Had it often enough: forgetting I SSHed into my Laptop (ArchLFK) or RPi (HomePI) and tried to execute commands for my PC (HomeLx).
It drives you crazy when your commands do not work as desired or changes are not visible. Then you realize you're on the wrong mashine. 😰
Its like searching for your Smartphone while having it in your hand.2 -
Ideas I've had over the years that could pan out and be useful:
SMS-DB: Stands for SMS-Data Burst. Used to allow those with low cell signal or no data plan to transfer data between a phone and some client via the standard SMS text space. Would be slow, but would act kinda like dial-up over SMS (as mobile lines are compressed on all service levels, even LTE, so traditional dial-up wouldn't work!) I have a general idea on how packets would be laid out, but that's about it so far...
everything2PNG: Allows one to transpose any file's data into a PNG with a 3 byte per pixel (full color RGB), which allows for a "compression" of sorts (about 91, 93% on preliminary tests) AND allowing further, more efficient compression of the resulting file. (Plus... it's just kinda cool to see files transposed as PNGs.) I actually have a simple transposer to go to PNG, but can't yet go back. Large files (around 600MB) use upwards of 4GB with efficient paging and other optimizations via NumPy so far, so it's not *viable* yet, but it's coming along nicely.
RPi-GPIO Interconnection Bus: A master/slave or round robin method to allow for Raspberry Pis to communicate using GPIO, which can help free up network bandwidth in RPi cloud computing clusters. At most, this'd allow for 4 bits used for pushing to the GPIO "bus", and 4 bits used for pulling from the "bus". 8 pins total are usually unused minimum, so either 3 or 4 pins for upload, 3 or 4 for download, and potentially 1 or 2 for commands, general non-data communication, etc. I made a version of this concept using Round Robin for a client, but it was horribly slow. (I also don't have distribution rights for the code, so i'm working from scratch.) Definitely doable. -
"Google Voice Kit - Install this image on your RPi 3B+ (or Zero depending on the kit version), pop this Hat on the GPIO pins, and press the button! It's that easy!!!"

TL;DR: New(-ish) dev looking for advice to improve workflow and new languages. Hopefully worth a read though :)
Newbie developer here, I took a web applications development class this year since I could take that at another campus rather than do general education courses at my home school, and I have learned and earned a CIW Certification for HTML5, CSS3, and JavaScript, though I know the certificates do squat if I can't apply myself to them, and I have learned PHP and MySQL.
I want to learn more, technically-applicable languages.
My setup is barebones (to a Linux diehard's eyes), with a gaming laptop that I do a lot of workstation stuff on, an RPi 3 B that I do some Linux-y stuff on, and a less-powerful Development Laptop (that I call a devtop) that I occasionally do work away from home on.
I'm sure most will cringe and weep at my workflow, as I use Windows 10 on both systems and the standard NOOBS software on the pi, and I use Brackets as my text editor, as well as the XAMPP AMP stack for testing.
My biggest questions are what could I do to improve my workflow, and what languages should I learn/apply myself to for real-world application (such as Node.js for live-updating server-side applications or C# for Windows applications)?
Thank you for taking the time to read this, any feedback is helpful! I'm just a high school student with a lot of enthusiasm for development!6 -
So i kind of fucked up...
I am currently living out of town and only have my laptop and rpi with me. Wanting to try something new, i decided to challenge myself to only use linux until i get back home, but i also wanted a new distro. (Oh and btw my only internet connection is provided by my phone and tablet, which is used as a hotspot, and because i already used all of my monthly data on the tablet now i only have my phone and an unlimited 128kbps connection which turns into a decent connection only after 11pm)
I downloaded the distro image last night and was planning to install it today, so i shutdown the laptop immediately after the download finished). If only i remembered that i had already wiped the old linux partition containing GRUB.
So now i need to wait until 11 pm so i can download another image on my rpi and flash it to my usb drive. Fuck me...
I guess i'll relax until then.1 -
may do an extreme rpi project…
is a self driving go kart or self flying drone cooler?
and for the drone, i think it would be easier, what do you guys think?
please answer - also for the drone, is there a way i could get it to connect from anywhere (within reason)? i know if it were a cell phone, i could get a signal from anywhere, but i don't want to pay for a monthly plan.4 -

one time i got past some parental software bullshit on a tablet by abusing the delay between opening a banned app and the redirect to the normal software at like age 7. (Doing so let me enable remote wipe through Google. bye bye software!)

Hey remote workers.
What would be your advice for someone with experience that's interested in exploring remote work.
I'd like to target this question to remote workers that live outside USA/EU/UK. Say South America, South Asia.
A little introduction.
I'm a full stack engineer, did one project in embedded systems with QT/C++/RPI can do backend in Python, Node, Java, C#. I have some experience with React Native (just 2 apps)
I currently I do full stack with Node, React, postgres and caching with couchdb.
I gather requirements, write the projects, proposals and then I do the implementation. (Really full stack, I kinda like it though, when I'm bored with code I pick up an issue and contact the client to socialize/get answers. I found out that nondevs like to feel they talk to a human not a robot)
I'm making about 600usd/month (dev in a poor country) working 30hrs /week. I'd like to ramp up my income, working remote part time to fill up about 50hr week.
What can I expect?
Where do I start?
Are there part time opportunities for working remote?
What kind of roles are in demand?9 -
Src: RPi FAQ
me: *wtf!?!*
what is the sense of this?
my option:
option #1: stop production of pi2 and sell only pi3
option #2: sell pi2 fast as a pi3 but without WiFi/BLE etc... if there are tecnical reasons that makes this not possible see Option #1

do you think that the new 300Mbit network interface of RPi 3B+ will be useful?
Personally I doubt....
it still need to share the bus with everything else.6 -

So, I am getting bored with my personal projects right now. I'm thinking about dragging out my Arduino and Raspberry Pi's and tinker with them for a while.
I need some inspiration, though. Just wondering what my fellow tinkerers are (have been) working on.6 -
Goal for 2019
- finish project I started in Q4 2018 and launch website with it
- maybe find some non invasive way to monetize this and earn some money
If I got time and power left :
- learn more autodesk fusion,
- design robotic arm using above tool
- print it in 3d
- program it with ROS arduino/rpi
- put it on some wheels
- make it driving around my flat
- make it pick up stuff for me -
I am thinking a little bit about buying Raspberry Pi, but I am not sure what to run on it. I am a webdeveloper, so I was thinking about server, but I would appreciate if you gave me some ideas.2

About a month ago my grandfather gave me the okay to work on a pi-hole and attach it to the router
So I did that yesterday, and he yells at me for it (because having a civil conversation is impossible with him) and says that we don't need "extra stuff" and says that I'll break the router.
I tried to explain how the process works but I was just shut down and interrupted.
He could have at least told me he changed his mind so I wouldn't have wasted over two hours of my day building and troubleshooting the device.
Mind you, he literally worked in hardware for 50 years and has had ham radio as a hobby for over sixty. -
So I had an epiphany. I have always thought of linux as a big ugly slow monstrosity. It occurred to me the only time I had used Linux was on rPis and similar devices. Then I threw vanilla Ubuntu onto a flash drive and booted my workstation to it.
My next point what is the most seamless dual boot solution. 😁

Hey people!
I need your brains!
I have this project, maybe you can help me with some ideea on how to implement it.
So, I need to read a lot of rfids. A lot. 100+ (It should work with any number of readers).
Next to the reader should be some leds to indicate a status.
Think of it as a matrix or readers. it should support x * y rows / columns
So, let's call it a node (the reader plus the leds).
Now, I have no ideea on how to link all those nodes to a raspberry pi.
For few it would be kinda easy, but when it goes to 100, I don't really know how to link all those together.
I was thinking about a cheap arduino to read the rfid and deal with the leds.
But I don't know how to link (in a bidirectional method) 100 arduinos to a rpi.
So, if you have any ideeas, that would be great.
Thanks!6 -
Aside from DevRant, what resources are available to pitch an idea in the hopes of recruiting a few developers for a side-project?4

someone brought something to school today, a "ac receiver" or "av receiver" or something? he pointed it at the board and turn it off, and i heard he opened someone's email with it? does anyone know what this could be?6

Is there anyone who successfully booted gentoo in aarch64 mode on the rpi 3? I can't get it to work. It gets onto the rainbow square then it shuts down like there is no kernel I guess. Sorry for asking here but there must be someone here who's kind enough to help.3

Fine then, keep your secrets.
```
root@RPi3b:/home/pi# vsftpd
500 OOPS: run two copies of vsftpd for IPv4 and IPv6
root@RPi3b:/home/pi# vsftpd --help
500 OOPS: unrecognise option: --help
root@RPi3b:/home/pi# vsftpd -?
500 OOPS: unrecognise option: -?

Anyone here who has managed to build a small laptop with a Raspberry Pi? I would love to use my iPad via USB connection as a screen for it but not finding the right apps for my needs3
-
Anyone have experience with non ARM Single board computers like the LattePanda for a price of around 80$ - 100$? The Board should be a server with a bit more power but it should save electricity. We have already six RPi and two Banana Pis...
-
making a self driving go kart controlled with a rpi, should i use python, java, dart, or something else? python seems like the obvious choice.
i plan on making it have google maps integrated, with netflix and music player, with a touchscreen.
i was thinking c++, but a gui with c++ didn't seem ideal.
what would you use?
also is an rpi too slow to make the go kart be *relatively* safe?3 -
I'm currently do some freelancing, and the job that I am doing at the moment requires interfacing with a Bluetooth device, but the company wants a Bluetooth repeater, to help extend or amplify the signal.
Is there anything like that out there or a possible Arduino or RPI implementation that I could use? -
Building atom on an RPI 2 with this fuckstickle of a package manager is a bloody nightmare. Works without issue on Raspbian Jessie, implodes into a spectacular clusterfuckeroni on Raspbian Stretch.
Been on it since yesterday, 10/10 weekend saved. -
Has somebody some good ideas for a new Raspberry Pi Project?
Or something whats really useful?
(Something without buying stuff just with the rpi)9
