Finally got the last of the hardware pieces for my pi book pro in today. Figured out how I'm going to lay it out and now to make custom cables to connect it all :D This old MacBook may yet breathe new life!

It finally hit me the other day.
I'm working on an IoT project for a late-stage ALS patient. The setup is that he has a tablet he controls with his eye movements, and he wants to be able to control furnishings in his room without relying on anyone else.
I set up a socket connection between his tablet and the Raspberry Pi. From there it was a simple matter of using GPIO to turn a lamp or fan on or off. I did the whole thing in C, even the socket programming on the Pi.
As I was finishing up the main control of the program on the Pi I realized that I need to be more certain of this than anything I've ever done before.
If something breaks, the client may be forced to go days without being able to turn his room light on, or his fan off.
Understand he is totally trapped in his own body so it's not like he can simply turn the fan off. The nursing staff are not particularly helpful and his wife is tied up a lot with work and their two small children so she can't spend all day every day doting on him.
Think of how annoying it is when you're trying to sleep and someone turns the light on in your room; now imagine you can't turn it off yourself, and it would take you about twenty minutes to tell someone to turn it off -- that is once you get their attention, again without being able to move any part of your body except your eyes.
As programmers and devs, it's a skill to do thorough testing and iron-out all the bugs. It is an entirely different experience when your client will be depending on what you're doing to drastically improve his quality of life, by being able to control his comfort level directly without relying on others -- that is, to do the simplest of tasks that we all take for granted.
Giving this man some independence back to his life is a huge honor; however, it carries the burden of knowing that I need to be damned confident in what I am doing, and that I have designed the system to recover from any catastrophe as quickly as possible.

In case you were wondering how I did it all: The Pi launches a wrapper for the socket connection on boot.
The wrapper launches the actual socket connection in a child process, then waits for it to exit. When the socket connection exits, the wrapper analyzes the cause for the exit.
If the socket connection exited safely -- by passing a special command from the tablet to the Pi -- then the wrapper exits the main function, which allows updating the Pi. If the socket connection exited unexpectedly, then the Pi reboots automatically -- which is the fastest way to return functionality and to safeguard against any resource leaks.
The socket program itself launches its own child process, which is an executable on the Pi. The data sent by the tablet is the name of the executable on the Pi. This allows a dynamic number of programs that can be controlled from the tablet, without having to reprogram the Pi, except for loding the executable onto it. If this child of the socket program fails, it will not disrupt its parent process, which is the socket program itself.

I just had the most intense nerdgasm of my life.

So I'm learning NodeJS (11/10, super fun, totally recommend) and I already had a chat script written up but it was only available to my LAN. Im hosting it using my Raspberry Pi Zero, which is surprisingly fast, and obviously sips power. Anyways, I FINALLY figure out port forwarding (Comcast made things harder, as per usual) and for the first time in my young life, I chatted with someone half way across the country... Using the hardware I set up, running the script I wote, on the network I configured.

I could have sworn I was drooling.

Today was a good fuckin day.

Bought a Raspberry pi with intentions of making a kickass hacking module. Ended up blinking the LED lights from GPIO pins. How's your life?

Hello devRant!

My name is Carter Schaap, a maker from SW Ohio. I've been voiding warranties for most of my life, and am currently at Great Oaks Tech School learning HTML, CSS and soon-to-learn JavaScript.

I dabble in C++ (because Arduino is a thing) and I'm learning Python because I'm getting into Raspberry Pi.

I can't wait to get involved in this community and do a lot of ranting.

Have a great holiday season!

{spoilers, i guess...}

In season 1 episode 4 of Mr.Robot, Elliott plans on using a Raspberry Pi to heat up the storage facility in order to destroy the cassette tapes stored there. If he can get the temperature high enough, it would render those tapes useless. I was just wondering, can a hack like this take place in real life?

So I got a couple of C.H.I.P. single-board computers a good while back because Raspberry Pi Zero was always out of stock.

I named them pringles, the smooth and synthetic one with a GUI, and ruffles, the sturdier and rugged one with a headless OS.

...They still lack a definitive purpose in life.

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. ☺

Not a rant, of course, life is amazing but why did I get a 3rd pack of stickers after only paying for one?

Also my new Pi arrived and I'm getting afternoon drunk.

Afternoon drunk = #1 drunk.

Have a great weekend, you fucks.

Sometimes life takes unexpected turns:

I studied mechanical engineering and did some "computer stuff" in my free time, you know, "programming" with Java, toyed around with HTML/CSS/PHP a few years ago, some local server stuff with a raspberry pi, nothing fancy.

Half a year ago i got hired as engineer first but they said they needed an "IT Guy" also.

What i did since then
*Researching, Testing and Planning the introduction of an ERP software
*Planning, coordinating and (partially) setting up a new server for the company (actually two cause redundancy (heavy lifting got done by our IT partner, its not like i suddenly know how to do the entire windows server administration)
*Writing 3 minor tools for some guys in the company in java
*Creating numereous excel vba scripts that make work a lot easier
*doing all the day to day business that comes up when absolutly noone know how to use a pc in the company
*consulting the boss about webshops and websites in general and finding a decent partner
*and some engineering

Did i mentioned that i studied mechanical engineering? I know nothing about all this, or rather, i know enough to know that i know not enough.

My current side project is creating a small intranet, so creating a new VM in Hyper V, setting up some OS (probably slim CentOS), getting a Webserver running and making it somewhat secure. Then i need to create some content, i am very close to just install a mediawiki and call it a day. If i write anything in PHP i fear that i make way to many erros or just reinvent the wheel, on the other hand, i couldnt find anything resembling what i need. I also had to create the front end side, i knew CSS around 2010, there is probably tons of stuff i dont know and i will make so many errors.

This is frustrating, everything i touch feels like i am venturing the beaten path but noone ever showed me the ropes so everything i do feels like childs play. I need an adult. Also the biggest Question remains: What i am?

FUCK YOU NODE JS AND FUCL YOU SYNOLOGY

Decided to give an old Synology DiskStation that sits at home slme new life besides just sharing files. Since Synology has SSH but not a full Linux OS, installed DebianChroot (so far so good). At one point I needed Node JS, so installed NVM and tried to install Node. Well guess what didn't work. Tried a few more things including directly downlosding node from the official node website. Trying different versions, the whole drill.

After about 5 hours of installing and errors, well really usfull errors like "There where 2 errors during installation" WELL HOW ABOUT YOU FUCKING TELL ME WHAT THE ERROR IS YOU FUCKING FUCK!

I found a formum wkith a guy haveing similar problems. Able to install legacy 0.10.x versions but not 4.x.x. Or 6.x.x oder whatever. He found that you have to have at least an ARMv6 compatible processor, otherwise it won't run. Checked it and well, that old fuck of mine only has ARMv5. FUCK! But honestly. You detect it's an ARM architecture. You detect it's not one of the v6 or v7, you try to install the general arm version, BUT YOU DON'T GET THE FUCKING IDEA TO MENTION TO CHECK WAHAT VERSION YOU HAVE AND IF THAT IS SUPORTED BY FUCKING NODE!

One afternoon wasted, at least I got a little more wisdom. Fuck do I hate Node now. On the bright side, I've ordered a Raspberry Pi and two cases for Harddisks, I'll create my own diskstation with blackjack and hookers (I realy hope you get that reference)! Fuck you Synology and Node JS (yeah yeah, it's not Synologies fault, but I'm mad anyways!)

Very excited, got my raspberry pi zero working over usb finally, gotta admit it took me a while to figure it out that the ifconfig IP assigned to the interface established isn't actually the raspberry pi's (seriously you don't want to see how far the visited google links go for all variations of "how to setup the otg ssh connection"), that only came to me once I was able to find the mini-hdmi to hdmi cable, before that it was a pure shitfest:

First I just tried all sort of configs, but the raspberry pi kept denying the ssh connection, slammed the microsd into my bigger Pi, even multiple times ran raspi-config, forced ssh to start in all possible ways, nothing.

Then I tried to use the TV-output on it together with my old small portable tv to maybe see some error-logs or the ssh not starting on the zero for whatever reason, even flashed a 2016 image thinking it is stretchs fault for not working, but then my fucking soldering iron cable disappeared, tried to quickly create my own, but that failed cause the 3.5mm connector it uses is different from the ones I had available, so I macgyvered a sketchy ass lose connection with male headers sticking through from the bottom and being sticked against the board with a female end on top, but the TV output wouldn't work, even with proper config options, so I gave up.

Some days later I've found the cable, connected it and realized the fucking IP it gets assigned is totally different from the interface, well fuck my life.

Atleast now I can make a clean image of that microSD and setup the portable laravel development raspi as I wanted, can't wait to try it once I get more time to fully set it up - btw even the internet bridge worked right out of the box, so I can easily use my laptops internet connection on the zero.

After falling down the Manjaro hole for months I yesterday decided to leave Manjaro for Pop!_OS. I lose a bit of performance and battery life, I gain a ton of UI polish, I gain a lot of package support, and I lose some hard earned nerd points.

My NAS has an easy to install Debian tool for file sync. I can use Etcher for making bootable USB/SD for my raspberry pi. Firefox is the default browser and I can use all my plugins and password manager out of the box. Apt is easier to use than pacman. Easier Python development setup. Docs are more often written for Debian. (For some reason I spent hours trying to get powerline and oh-my-zsh working right in manjaro’s xfce terminal before giving up.)

No! Why ?!
(Life of Pi)

I recently bough a HifiBerry Pro DAC+ ADC for my raspberry pi.

That is when I remembered....

Linux is bad, but embedded Linux is worse.

I just wanted to connect via Bluetooth to a speaker and play sound through a microphone.

Unfortunately, after hours of configuring software, Bluetooth drivers and then testing python scripts with PyBluez, I still hate my life.

I guess the fancy new Linux GUIs (that compete with windows) really do not work correctly, because I swore the Bluetooth symbol was lit up in the top right.....

Kill me.

!rant
Although I wouldn't change my main os (os x), I'd like to have a linux VM ready on my machine.
Which distro would you guys recommend?
To give you a quick description of how advanced I am with operating systems, I have used windows for the majority of my life (I'm 19), have recently switched to osx (when the new mbp came out) and have spent about 3-4 months using only ubuntu in between my windows/osx switch. Besides that, I've only done some minor projects with a raspberry pi.

I been looking over my profile and god it's been a while, programming as still been going on in the background but more for game mods and alikes, kind of been lazy but same time dealing with life.

I really had forgotten my passion for tech and programming it's just become a tool I know and use and I kind of feel bad for doing that. I got in to computers when I was 6 years old built my own PC our of random spare parts at 7, was teaching family members how to repair there own pcs by 9 at the age of 11 was helping with the schools computer department repair and fixing networking problems and my ideas and comments mattered.

Now I am an adult ... Sadly it seems the enjoyment of any idea is shot down with some rude remarks from another Dev, but isn't the point we all see a problem different so we all can contribute?

Like I said I never worked away from computers or programming but now I more like your little side computer repair shop I can do it, I get the job done but the passion isn't there and the end result reflects it.

I believe it's the human part what put me off not just others but myself, I used to put my heart in to my projects and when someone comes alone and rips them apart for let's say a spelling mistake what I state everywhere I am dyslexic but seems to be over looks alot. I became more stale in what I was willing to take on. My own websites now reflect this I am using crappy reinstalled software over me doing it myself.

But the passion for the idea what tech and programming never left I just hope one day soon I am enjoy it again, the wow factor is still there, god there is some talent out there and some of them people I meet before they became big but my aim was never to be come big I would be happy to be on a small project what only as a few eyes on it as long as it makes a difference and that's my problem tech like everything as become so commercial.

Even small projects are ran like a company and the wow factor is gone or the risk factor of trying a unknown way is dismissed for trying to keep face.

If I was born 20 years before right now I would be glad to slow down but I am 30+ and seen the world change so much in this last 10 years where I can do it but .... Why would I do it, when most cases it goes out of my moral ideals

I still mess around with teck, I still have Pi's kicking about and you bet your bottom Dollar I will be trying to get a Pi 5 lol

The love of tech hasn't gone but the communities I enjoyed have, I know this is a me not adapting but I don't need to adapted, I want what we do to matter to someone to make a difference, and I mean with there life's and wellbeing not there bottom line.

If you have any communities to look in to please comment below and of you was able to read this then OMG I am so sorry, I didn't proof read this or anything it was just a little rant about how I become disconnected from the world I have always found enjoyment.

I slipped away to game at late but this last few months I seen myself wanting to be apart of a project or community for tech/programming and even just be a voice helping even someone else get the answer.

I do still have hope for the geeky nerds of yester years even if we are now just a relic of the past lol

Well sorry to put anyone's eyes though this lol enjoy your rants guys and keep up what ever projects your working on.

Trying to figure out how the below code works. Everything is straight forward. The code works as I ran it in qbasic in dos emulator.

But for the life of me I cannot figure out wth cap1 and cap2 are. I debugged the code and saw values being set, but I cannot figure out where the data is coming from. I assume it is somehow related to the function declarations. Been 20 years since I did anything with qbasic. Maybe some other old fogie can tell me what is going on here:

DECLARE FUNCTION integrate (sample, cap, tc)
DECLARE FUNCTION differentiate (sample, cap, tc)
COMMON SHARED accumulator
CONST pi = 3.14159
SCREEN 9: CLS

FOR timeConstant = 10 TO 600 STEP 100
accumulator = 0

FOR a = 0 TO 22 STEP .01
wave = 0
FOR h = 1 TO 10
wave = wave + SIN(a * h) / h
NEXT h

lopass = integrate(wave, cap1, timeConstant)

IF wave > lopass THEN
trigger = 1
ELSE
trigger = 0
END IF

hipass = differentiate(trigger, cap2, 20)

PSET (a * 30, 50 - wave * 20), 15
PSET (a * 30, 50 - lopass * 20), 14
PSET (a * 30, 100 + timeConstant / 4 - trigger * 15), 2
PSET (a * 30, 270 - hipass * 20), 15

NEXT a
NEXT timeConstant

END

FUNCTION differentiate (sample, accumulator, tc) STATIC
fsample = tc
leakage = 1 - EXP(-2 * pi * 1 / fsample)
capAvg = leakage * accumulator
accumulator = accumulator - capAvg + sample
differentiate = sample - capAvg
END FUNCTION

FUNCTION integrate (sample, accumulator, tc) STATIC
fsample = tc
leakage = 1 - EXP(-2 * pi * 1 / fsample)
capAvg = leakage * accumulator
accumulator = accumulator - capAvg + sample
integrate = capAvg
END FUNCTION

The output looks like the image.
