Mac: Suddenly turns off
Me: Fuck my code..F***
Mac: No response at all
Me: reset SMC etc etc
Mac: I am dead (no battery detection, dies after 10 min on power adaptor)
Me: Skips a heart beat..(Git, oh yea git)

**Takes Mac to store, After diagnosis**

Apple Freaking Genius (AG): Your Mac has a mother board problem it needs to be replaced.
Me: Hmm what is the problem exactly??
AG: Issues in logic board and some other components.
Me: How much?
AG: Out of warranty so $$$ (60% of original amount)
Me: (wtf?) Really
AG: It's entire motherboard replacement .. bla bla

#ThugLife #Engineer

So I have complained to our landlord about a noisy neighbor who keeps blasting shitty music at midnight, and technically its against the law as well, but this bitch ass joke of a human being ignored even the most highest of authority.

Seeing I can't solve it with democracy, I finally gave up with any reasonable type of way to restrain this motherfucker (even calling police didn't help) and went full asshole with him

I know his WiFi uses WPS PIN, but I'm not gonna throttle his network, I want to piss him off so much he'll regret living beside me, or at our place entirely.

So I performed a Evil Twin attack, I had my Raspberry Pi act as a both cloned AP and a deauther. Finally the plan came to effect.

I ran the deauther in his AP, effectively disconnecting his devices, and had the devices connect to the cloned network. The primary aim of my attack is to annoy this bitch ass to the point of no return. The project I used serves a website on the cloned AP like a update for his router. I intentionally made it run overnight, blasted Lo-fi hip hop and went to sleep. Before I dozed off, I can hear their scream of rage because they can't blast their music at full volume (waddaya guess, they use Spotify).

I finally woke up the next day, and I find neighbor complaining about me, and they were trying to tell the landlord I was hacking them. It's technically true but its not as bad as domestic disturbance for a full fucking week.

Landlord asked me if I did it, I declined, she believed me (I know she does because she knows I'm a pure soul unlike this mofo). Then he left frustrated, threatened to sue me for hacking.

I just smickered, he can't really prove anything unless I was being sloppy.

Nowadays I get good sleep and finally we live in a quite peaceful place now. Now you may ask, what happened to that guy? After he threatened me, the next night he found his things outside his own room, he was kicked out by the landlord.

Moral of the story: we ain't hating on your music taste but don't showcase it like its the most important thing in the world when everyone is sleeping. Case and point, don't be an asshole

I asked my mom if I can buy myself a raspberry pi for my birthday.
No matter what I show or say to her, she won't stop telling me to bake my own raspberry pie. ;-;

That's it. I fucking quit.

Over a month of unpaid work, developing your stupid course, only to get a high-quality outline rejected because "it's not what we wanted" again.

First outline, fuckers ask to do something with a Raspberry Pi and Yocto. Fine, but no Yocto as I don't know anything about it and the coworker doesn't even have a Raspberry Pi to flash the images on. Micromanagement guy (god I hate that word) agrees, fine no Yocto then. So no Yocto it is.
2 weeks later... Course outline is finished. Review stage.. rejected. Needs moar Yocto.
Fine... I'll include Yocto. Coworker was put off the course, I'm exclusively on it now. Time to do it well and get my feet wet with Yocto.
2 weeks later... Course outline is finished and looks pretty good. Review stage.. rejected. Needs less Raspberry Pi. Do it without the Raspberry Pi.

An embedded systems course whose core component is that fucking Raspberry Pi. Omit it they said. WHAT?!!
"Oh yeah but there's this other course that's selling like hot pockets, we can just redo that in videos. Make it more like that course."
You.. you can't be for real, can you? If students want to take that course... What makes you think that they wouldn't just pick.. *that damn course* then?

"But hey" micromanager said, "don't loose hope and confidence, I'm here🤪"
🤪. That describes your level of competence pretty well, you stinking piece of apeshit.
Go back to your micromanaging, at least you don't completely fucking suck at that.

2 times rejected because YOU fucking company's board can't describe your desires in a course properly. You know what, I think I'm starting to understand why web devs keep on complaining about indecisive clients now. Because you know company's board, you seem a lot like those clients from hell. Eat shit.

🖕

3 rants for the price of 1, isn't that a great deal!

1. HP, you braindead fucking morons!!!

So recently I disassembled this HP laptop of mine to unfuck it at the hardware level. Some issues with the hinge that I had to solve. So I had to disassemble not only the bottom of the laptop but also the display panel itself. Turns out that HP - being the certified enganeers they are - made the following fuckups, with probably many more that I didn't even notice yet.

- They used fucking glue to ensure that the bottom of the display frame stays connected to the panel. Cheap solution to what should've been "MAKE A FUCKING DECENT FRAME?!" but a royal pain in the ass to disassemble. Luckily I was careful and didn't damage the panel, but the chance of that happening was most certainly nonzero.
- They connected the ribbon cables for the keyboard in such a way that you have to reach all the way into the spacing between the keyboard and the motherboard to connect the bloody things. And some extra spacing on the ribbon cables to enable servicing with some room for actually connecting the bloody things easily.. as Carlos Mantos would say it - M-m-M, nonoNO!!!
- Oh and let's not forget an old flaw that I noticed ages ago in this turd. The CPU goes straight to 70°C during boot-up but turning on the fan.. again, M-m-M, nonoNO!!! Let's just get the bloody thing to overheat, freeze completely and force the user to power cycle the machine, right? That's gonna be a great way to make them satisfied, RIGHT?! NO MOTHERFUCKERS, AND I WILL DISCONNECT THE DATA LINES OF THIS FUCKING THING TO MAKE IT SPIN ALL THE TIME, AS IT SHOULD!!! Certified fucking braindead abominations of engineers!!!

Oh and not only that, this laptop is outperformed by a Raspberry Pi 3B in performance, thermals, price and product quality.. A FUCKING SINGLE BOARD COMPUTER!!! Isn't that a great joke. Someone here mentioned earlier that HP and Acer seem to have been competing for a long time to make the shittiest products possible, and boy they fucking do. If there's anything that makes both of those shitcompanies remarkable, that'd be it.

2. If I want to conduct a pentest, I don't want to have to relearn the bloody tool!

Recently I did a Burp Suite test to see how the devRant web app logs in, but due to my Burp Suite being the community edition, I couldn't save it. Fucking amazing, thanks PortSwigger! And I couldn't recreate the results anymore due to what I think is a change in the web app. But I'll get back to that later.

So I fired up bettercap (which works at lower network layers and can conduct ARP poisoning and DNS cache poisoning) with the intent to ARP poison my phone and get the results straight from the devRant Android app. I haven't used this tool since around 2017 due to the fact that I kinda lost interest in offensive security. When I fired it up again a few days ago in my PTbox (which is a VM somewhere else on the network) and today again in my newly recovered HP laptop, I noticed that both hosts now have an updated version of bettercap, in which the options completely changed. It's now got different command-line switches and some interactive mode. Needless to say, I have no idea how to use this bloody thing anymore and don't feel like learning it all over again for a single test. Maybe this is why users often dislike changes to the UI, and why some sysadmins refrain from updating their servers? When you have users of any kind, you should at all times honor their installations, give them time to change their individual configurations - tell them that they should! - in other words give them a grace time, and allow for backwards compatibility for as long as feasible.

3. devRant web app!!

As mentioned earlier I tried to scrape the web app's login flow with Burp Suite but every time that I try to log in with its proxy enabled, it doesn't open the login form but instead just makes a GET request to /feed/top/month?login=1 without ever allowing me to actually log in. This happens in both Chromium and Firefox, in Windows and Arch Linux. Clearly this is a change to the web app, and a very undesirable one. Especially considering that the login flow for the API isn't documented anywhere as far as I know.

So, can this update to the web app be rolled back, merged back to an older version of that login flow or can I at least know how I'm supposed to log in to this API in order to be able to start developing my own client?

I taught my 9yo sister to SSH from my Arch Linux system to an Ubuntu system, she was amazed to see terminal and Firefox launching remotely. Next I taught her to murder and eat all the memory (I love Linux, as Batman, one should also know the weaknesses). Now she can rm rf / --no-preserve-root and the forkbomb. She's amazed at the power of one liners. Will be teaching her python as she grew fond of my Raspberry Pi zero w with blinkt and phat DAC, making rainbows and playing songs via mpg123.
I made her use play with Makey Makey when it first came out but it isn't as interesting. Drop your suggestions which could be good for her learning phase?

*makes course outline*
Management: Um yeah make the outline similar to this course from earlier
Me: Hmm, so Yocto etc.. well that'll require a good amount of research because I've got no idea what Yocto is or how I'm supposed to use it.
*researches about Yocto, prepares build VM and Raspberry Pi target, thinks of how on Earth I'd make my coworker without Raspberry Pi interface with it from across the world*

2 days later..

Management: Yeah actually we don't want Yocto. Just do simple stuff like application development, GPIO etc.
Me & co-worker: Awesome mate! That'll make things a lot easier. Except for the 2 days of lost work, but we can live with that if it's just GPIO and such.

3 days later..

Management: guys your course outline sucks. Do it all over again, we want Yocto to be in it after all.

YOU MOTHERFUCKERS!!! Why don't you behave a little bit less like a fucking client that doesn't know what they want for once?!!

I automated the process of downloading songs from YouTube and transferring them to my phone.

This is how it works, very simple:
- I have a youtube playlist in which I add songs that I'd like to download
- When I run my python script, it parses my playlist and checks to see if I have added any new songs that aren't already downloaded
- Uses a library to download MP3 for all the songs I want to download
- Transfers all those MP3 files to a designated folder that is tracked by Google Music manager
- Google Music manager syncs those songs to my phone and downloads them for offline playback

That's it 😎 No need for YouTube Red

I'm going to run this script 24x7 on a Raspberry Pi, so everytime I add a new song to the playlist, script starts it's job without me running the script manually.

TL;DR: check polarity before plugging your DIY circuits into others!!!

*goes off to watch some Lucky Star and drink some booze*
*notices phone battery dying after 3rd pint*

But my charging cable that Huawei delivered with this thing is way too short... Well that ain't no problem, I can make one of my own 😎

But I'm tipsy.. sound I really enter the workbench in this state?

*goes off to build a charging cable anyway*
But what was USB-A male connector's polarity again? Oh, there's the fan's USB connector that I've made in the past. Let's check on that one. So, left is positive and right is negative?

*solders the wires on*
Snip, strip, stick, done! Well that was easy. I guess that all those failed soldering attempts and lost pads in the past as a means of training did pay off in the end!

*plugs phone into Raspberry Pi media center through new charging cable*

Strange sounds coming from the speakers.. well that's odd. Reverse polarity or maybe the Pi can't handle a 1A load from my phone?

*plugs phone into the 5V 5A charging hub that I've made earlier*
That oughta do.. current limits should be no more in that thing.

*charging hub makes high-pitch noise similar to the Pi speakers*
Definitely a reverse polarity, isn't it :') let's check on the Gargler...
Oh shit! It is a reverse polarity mistake!!! Should've checked this earlier >_<

*resolders wires properly*
Alright, finally done.. as I'm writing this post, my phone's charging from the Raspberry Pi through my fixed charging cable now...

Lesson learned. Always check on the internet what the pinout is before soldering anything, don't solder while tipsy, and be fucking grateful that this phone has reverse polarity protection in it.

Nexus 6P with all its shortcomings regarding power delivery and battery management, luckily it's got reverse voltage protection features built-in. Otherwise it might've costed me my phone. Always double-check before plugging anything into something else!!!

I bought a raspberry pi a while back, and I have no idea what to do with it. I know nothing about electrical engineering or Python (as I believe that's the language you use to program the pi). Any ideas?

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.

*desolders Ethernet, USB and GPIO rails from Raspberry Pi to decrease height*
(Desoldering that shit from a Pi fucking sucks btw, no idea what solder or pads they use but it's garbage)
*boots up Raspbian to see whether it still works and to set things up*
...
Oh shit.. I need keyboard and mouse for this :') fuck me I guess... Long live planning ahead. Does there exist a KVM over TCP/IP yet? 😅

Why are all flat and fully closed design raspberry pi zero cases either only available in a fucking $100 bundle or have holes somewhere to accomodate for the fucking pinheaders or just random dickholes, for no fucking reason.

Raspberry pi worked perfectly fine. Reinstalled the sd card for some reason (on purpose) and now, no matter what system I flash, it always crashes at stone point. That point is random every fucking time.

I just want this fucker to work 😥

So I've got this raspberry pi 3 and no inspiration what to use it for.. and it bugs me, just sitting there taunting me: -"you aren't very creative are you?" So.. ideas and suggestions?

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.

had wished for a raspberry pi as christmas present, ideally with a pi cam on top.
now i've got a pi cam😏 ... and no raspberry pi😐🤨😅
that was unexpected

Well, I got 2 mega arduino kits and a raspberry pi over xmas (and no experience with either), plus unemployment, so my goals are learning the hardware side of things this year.

Also, hi devRant.

In fact I'm a sinful dev, so that I can't easily decide which one is worst. From indenting with tabs, or using nano instead of vim/emacs, to hardcoding database credentials on server, to many hacks and workarounds I use as actual "fixes" when the deadline is upon me and I've tried all I could. But it always led only to my own regret. For instance, my latest sin was that I prefered Debian over Arch and used proprietary graphic drivers to speed up my new setup. But ended up with a curse from St. Ignucius. (check my last rant)

But my worst sin probably goes to when I was "printf-debugging" some issue for a GSM controller on a raspberry pi. I forgot to remove one little print line and deployed the new "fixed" version. I didn't follow that project after that for like a month or so, when the client posted back the device and said that "it just doesn't work anymore". It seemed that raspbian didn't boot beacause the sd card was curroptted. I dd'ed through the card and I noticed that there are billions of lines of "DEBUG:: reading stream from 192.some.shitty.ip", took almost all over the 32G sdcard. Just as I suddenly remembered the cursed line I just added a month ago, I declared the sd card dead with no hesitation, dunce-commented the line (so the history would remember), implemented a time out for the thread containing it, setup a journald unit for my service and removed the redirection of process output to a log file, found a new sd card and installed everything again, and finally posted back the new "fix" to the client.

Moral: Never comfort yourself for the sins you have commited in the past kids, they certainly will come back to you. And also not to do any io especially write to a file on an SD card with ext fs, in a potentially infinite loop with no timeout.

P.S: I'd posted my last rant just before the new week rant last nigh. I really liked the St. Ignucius meme so decided to create a new one. He's very adorable :)

Nothing ticks me off faster than non working websites or apps of big companies.

For example how can it be that the Lufthansa app has no offline support for ticket stuff and loads like all their requests worldwide would be handled by one raspberry pi A...
YOU GOT THE MONEY SO GET THIS SHIT DONE

Been in Microsoft stack too long. Opened up bash terminal on the raspberry pi I just setup...

Its been 6 hours and it felt like 20 minutes. I had no idea I missed this until I started messing around again.

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. ☺

I learnt something from every single project I made, but this one... it was really different, new language, new library, new hardware.

Problem:
there's an infopoint in a place, that was really hard to use (ball mouse over a monitor)

Solution:
make the screen be touch.

Developing the solution:
- after a bit of research I find out there's a library/project called OpenCV
- there are example programs that detect hands written in C++ (which I know) and Python (which I don't know)
- the whole infopoint works on a raspberry PI, with raspbian (I'm not new to linux, but it's somehow different, plus tons of customization)

So I spend like 3 weeks trying to understand how to make it work, at first, the webcam was on the TV and you could move the mouse just by shaking your hand, but it didn't work too well, so we tried making the webcam look at the screen and then calculate the differences between "no-hands" and "user-hand", but should have been calibrated, wasn't too precise... dropped solution.

put the webcam 30cm above the screen, let it just analyse a few centimeters of sight from the screen and it worked flawlessly, BUT it could just recognise the horizontal axis => had to rework the infopoint UI to make it dumb-easy

It all finally worked, I learnt python, openCV, a bit of photography

Then hated it all and decided to never do that again

fdisk, cfdisk, diskpart and other tools CAN SUCK MY DICK.

I needed to restore my raspberry pi microsd from 200ish MB back to 16 GB and could find NO WAY of restoring it from my pc. maybe there is some ajbd -asdkasd -adkahdh IUYGFG_&38726283746 sdkfjksjf command that does that but I don't give a shit.

I plugged it into my camera instead. One second and my microsd was restored.

Canon doesn't care about your fancy partitions and other shit, it's just fucking blasting, it is like IN YO FACE. I love it.

So our new hardware guy who is being managed by our lead embedded developer had the task of designing me an expansion board for my Linux board. The Linux board uses the 40 pin expansion like the raspberry, bananna and orange pi family and as you all know there are many different types of expansion boards for this.
I said at the start come to me and tell me what you want to connect to before deciding which pin you connect to so it is less work for me with Linux board configs and drivers.............
No no no we will sort it all... erm.....
So today they come ask me if they can use an SPI port for GPIO and I am like erm... why there is plenty of GPIO...
It turns out they have been designing the board based on the pin outs of an expansion board and not the actual connector of the Linux board.. I mean seriously WTF!

More of a rave than a rant.

My Dad was having some trouble with a game disconnecting on the PS4 and he read somewhere that it might be a problem with our home router. I didn't think it would be, as every other game works fine. But there was no talking him out of it. And to be fair the current router WAS kind of old.

So I have a look at the one he's decided to buy and it's some massive triple-antenna beast for well over a hundred pounds. I felt like such a weapon might be overkill for 2 people in a house, but did say that it would definitely help with connection issues in some rooms and I kind of wanted to play with it.

So he got it and oh am I glad he did. It has so many fun toys, including a built in VPN. Right now I live abroad so there's a few services I used at home that I can't access, I was literally just considering buying a vpn the other day. I found this while setting up port-fortwarding for my Raspberry Pi to run a discord bot I'm building. I had condisered putting a VPN server on the Pi but this works too!

It also has built in DDNS from ASUS, which IS cool, but our IP hasn't changed in years so I'm not sure we'll need it. I set it up anyway just in case though!

It seems that every Pi day, I end up with a new Raspberry Pi that I got sometime before it. First, a 1, then a 2+3, now I have a Zero as well. Next year, I'll have a cluster of 3s. No reason, just want to mess with it.

Samsung Smart TV becomes Samsung Dumb TV.

Welcome back dear readers, to the next installment of my Raspberry Pi / Pi Hole / MitM box adventure!

For those of you who are new to this story, I'm a long experience programmer who knows very little about his home network or networking in general and has constantly been going over his 250GB data plan because 'rona, and thus, wants answers to "where is the data going".

So, I got the Pi, codenamed Mini-Beowolf, positioned between the modem and router... worked some fuckin systemd.networkd magic (which was sort of easy... but was hard cause I'm new to it) and viola, this son of a bitch passes through the ethernet and doesn't even show up on the router. Fu-King Beastly, I love it.

Now to static IP all my devices so I fire up my trusty TP-Link admin portal. I should add here... I've visited this admin about a total of 10 minutes prior to this when I set this wifi router up and just let it do DHCP.

So I'm getting to know my admin portal... I've got most of my devices connected to reserved IPs... and I find this one fuckin device reporting as "localhost".

Now, I've got a MAMP install... but it hasn't been running. But still I thought for sure it was just MAMP run a bit amok.

But no... it was my fucking Samsung "Smart" TV. That piece of shit is, and apparently has been reporting its device name as, sure as shit, fucking "localhost"... PROBABLY FOR YEARS.

Now, IDK how that didn't cause me any major problems over the years, and I read quite a few forums about people who it did mess up their network. So I resolved to rename the Samsung TV device.

I found the spot in the network settings of the TV... I changed the name from the pick list of rooms in a house like "Living Room" and "Bed Room", then I tried entering my own device name. But no matter what I picked, or no matter how many times I restarted/reset that TV the network name is ALWAYS "localhost".

Even though somehow my network survived this long... I'm not standing for that shit.

My Samsung TV is now blocked COMPLETELY at the router level. (After I ran one last factory reset and update)

The kicker? That Pi I built has a Samsung SSD... so I'm blocking Samsung WITH FUCKING SAMSUNG.

Needless to say, these are likely among my last Samsung purchases.

Join me next time when I FINALLY try to turn Pi Hole on and then get a tcpdump (or some other lesser output from the tcp stream) going.

Ok, I will build my own
Poor laptop, prepare for hours of gcc grind while we cross compile what we need 😛

Took the day and rebuilt my home network with no major issues along the way.

Migrated to a new NAS and gave a Raspberry Pi a new life as a PiHole + DHCP.

Rant: Why can't things always go this smoothly on my projects? 😎

So I set up a raspberry pi to control my bedroom lights last year. I decided I wanted to add some more features to it and for the first time since I created it, started looking through the code I wrote.

First thing I noticed was the excessive amount of files I have. Like I get that I just wanted to throw this thing together as quick as I could but did I really need to create a file specifically for storing a 1 or 0 depending if the lights were last turned on or off for a startup check.

Secondly, I seem to have 2 index.html files for some reason.

And finally, the code itself is pure spaghetti. The website is running with a python script, which sends calls to a nodejs server, which executes additional python scripts to control the lights. No comments anywhere, and badly named variables are also a great combo.

And finally there is the occasional "Why the fuck isn't it working, fuck it I'll just unplug the pi and reboot it" that I have been dealing with lately.

Oh and don't forget that the log file is spammed by a debug message that is printed every minute.

God I feel so ashamed. I was proud of this until I looked at it just now.

Colleagues in IT Student Assistant's desk: [Watching Kimi No Nawa]

Meanwhile me : [Creating 2 small kubnernetes Raspberry Pi Clusters on my free time]

Talk about dedication.

Haven't started this project yet, but I've been considering ordering another Raspberry Pi and turning it into a voice assistant using Mycroft. I've been wanting to play around with IoT stuff for a while, and since I'm practically confined to my apartment for the foreseeable, there's no better time to get started.

Gotta learn myself through vim and tmux because I have no choice. My laptop burst and all I have is a Raspberry Pi with Raspbian core + MATE DE installed. Don't really wanna use heavy stuff with it because it'll become really snappy.

Oh well, as long as I can code.

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.

Finally got my wall up to my desk in whiteboard. 4' by 8' sheets cut to fit the whole wall with a 1/8" clearance at the top. Ignore the raspberry pi, I have to set it up this way because I have no USB network adapter or long enough Ethernet cable. There should have been a magic mirror where the box is but on that specific spot in the wall the studs are only 13 1/2" instead of 14" like they should be...

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.

fuck my life

I have always been interested in computers. when I was in second grade, I decided I was no good at electronic circuits, and decided I wanted to program instead. My dad told be to check out free basic, and I immediately downloaded FBIDE, and followed tutorial videos on YouTube. once I finished the videos, I started to write mad libs programs. I made various types of calculators, etc. and loved it, so later I learned a bit of VB. I messed with that a bit, but didn't like it too much, and started web developing. The moment I saw some JS code, it was like an instinctive second language to me. I learned js and started making some ugly, but cool interactive web pages. When computercraft came out for minecraft, I learned lua and got a deeper understanding of programming. Now, I am using node to build a personal-use IoT server and currently making a drone flight program using a raspberry pi

There is no joy in life

So I finally managed to set up networking on my 3D printer's raspberry pi: now it can connect to my phone's hotspot or to my uni's wifi network, depending on which is available.

Then I set up OpenVPN, using a remote server as a middleman so I can connect to the printer remotely and start/stop/monitor prints from anywhere.

Everything works great, except for one thing: whenever the Pi connects to the uni's network first, OpenVPN fails to start and connect to my server, rendering the printer unavailable (unless I use an ethernet cable, but that's not a viable operation since I need to lift the printer, and it's heavy).
The only for it to work as intended is to either:
a) keep my hotspot active (which kinda defeats the point), or
b) let it connect to my hotspot first (so that OpenVPN can start properly) and then turn off the hotspot, allowing the printer to reconnect to the uni's wifi and reconnect to my vpn.

Why won't things just work the way they're supposed to? 😭

I have a simple task to do but I want some of you guys' input.
So I need to set up a button that when pressed will cause a video to play on a nearby TV.
- This must happen instantly (or at most with a second or two of delay)
- Video will be "self-hosted" (not on Youtube or something) and will mainly stay the same
- No idea what kind of TV I'll get to work with (might be smart, probably not)

I'm thinking a Raspberry Pi with a button connected to it's GPIO and a static image displayed on the TV when idle. That way I can also manage/maintain it remotely via SSH and it should be reliable enough but on the other hand this could be an overkill...

Post your 2 cents please and thank you :)

This is why we can never have enough software developers

It's true. No matter how many people learn to program, there will never be enough people who know how to program. They don't have to be very good at it either. It is now a required skill.

Minimum wage in first world countries is way above 5$ per hour. A Raspberry PI 3B costs 40$, or at most 1 day of work for the worst paid jobs. And it will run for years, and do routine tasks up to thousands of times faster than any employee. With that, the only excuse that people still do routine tasks, is the inaccessibility of coder time.

Solution: everybody should know how to write code, even at the simplest level.

Blue-collar jobs: they will be obsolete. Many of them already are. The rest are waiting for their turn.

Marketing people - marketing is online. They need to know how to set up proper tracking in JS, how to get atomic data in some form of SQL, how to script some automated adjustments via APIs for ad budgets, etc. Right now they're asking for developers to do that. If they learn to do that, they'll be an independent, valued asset. Employers WILL ask for this as a bonus.
Project Managers - to manage developers, they need to know what they do. They need to know code, they have to know their way around repositories.
QA staff - scripted tests are the best, most efficient tests.
Finance - dropping Excel in favor of R with Markdown, Jupyter Notebooks or whatever, is much more efficient. Customizing / integrating their ERP with external systems is also something they could do if they knew how to code.

Operations / Category Management - most of it would go obsolete with more companies adopting APIs as a way to exchange important information, rather than phone calls and e-mails.

Who would not be replaced or who wouldn't benefit from programming? Innovative artists.

A lot of it might not be now now, but the current generation will see it already in their career.

If we educate people today, without advanced computer skills and some coding, then we are educating future deadbeats.

With all this, all education should include CS. And not just as a mandatory field or something. Make it more accessible, more interesting, more superficial if needed. Go straight to use cases, show its effectiveness in the easiest way possible. Inquisitive minds will fill in the blanks, and everyone else will at least know how to automate a part of their work.

A whole day yo set up an ethereum node on a raspberry pi zero... No mining. No wallet. I'm loosing it, people.

Maxi-Rant, rest in the first comment!

Yay, I've caught up with my "watch later" list on YouTube! Next thing: Just quickly go through my subscribed channels and add old videos that I haven't seen yet to the watch later list so that I have more stuff to watch the next months. The easiest way to do that is to go to the "all uploads" playlist of the channel (that is luckily always linked now, it used to be hidden sometimes) and use "add all to" to get them on my playlist. Then sort out the stuff that I've already seen and turn on automatic sorting by date, easy. Yeah...
Firstly, in the new design there's no "add all to", I have to go to the old design. For my own playlists, there's a handy "edit" button to do that, but on other pages I have to do it manually. Luckily I have set Ctrl+Shift+1 as a shortcut for "&disable_polymer=true" long ago.
Next surprise: On "all uploads" playlists, there is no "add all to" button. It's on every single other playlist on YouTube, including "liked", "watch later", "favourites" and so on, just not there.
Fine, I'll just abuse my subscription playlist script that I already have by making a copy of it, putting the channel IDs in it and setting the last execution date to 1.1.2001. Little problem with that: Google apps scripts can run for at most 5 minutes and the YouTube API restricts it to add one video per second. So it doesn't work for more than 300 videos. I could now try to split it up by dates, but I didn't write the script myself and I don't know how it sorts the videos to add, so I'll just google for another solution instead.
Found one: Go to the video overview of the channel in the old layout, Ctrl+Shift+I, paste this little Javascript thing and it automatically clicks all the little clocks that add the video to the watch later list. Yay, that works! Ok, i'm restricted to 5000 videos, because that's the maximum size of a YouTube playlist, so I can't immediately add all 8000+, but whatever, that's a minor problem and I'll sort out later anyway. Still another little problem: For some reason I can't automatically sort the watch later list. Because that would be too easy.
But whatever, I'll just use "add all to" from there to add it to my creatively named "WL" list. If that thing is restricted by the same rate limit of 1 video per second, it should be done in about 1½ hours. A bit long, but hey, I'm dealing with 5000 videos. Waiting 2 hours... Waiting 3 hours... Nothing happens. It would be nice if it at least added them one by one, but no, it waits an eternity and then adds all at once. At least in theory, right now it does absolutely nothing.
Shortly considered running it for more hours or even days on my Raspberry Pi, but that thing already struggles when using Chromium normally, I shouldn't bother it with anything that has to do with 5000 videos.
Ok, what else can I do then? Googling, trying out different things, mainly external services that have their own concept of "playlists" and can then add them to an arbitrary playlist later...
Even tried writing my own Java program with the YouTube API, but after about an hour not even the example program in the YouTube API tutorial worked (50 errors and even more open questions, woohoo), so I discarded that idea.
Then I discovered "DiskYT". Everything looked like it would work and I'm still convinced that I can do it with that little pile of shit. Why is it a pile of shit? Well, for example the site reloads itself after a while, so it can at most add 700 videos to a playlist. Also I can't just paste the channel link (even though it recognises those links, but just to show an error message that it can't copy from channels). I can't enter/paste URLs, I have to drag them. The site saves absolutely nothing (should in theory work, but in practise it doesn't), so I have to re-drag everything on every try. In one network, the "authorise YouTube" button (that I have to press again on every computer) does absolutely nothing ("inspect" reveals that there isn't even any action bound to the button), in another network the page mostly doesn't work at all or the button to copy from playlists is suddenly gone or other weird stuff. Luckily I have the WiFi at home, there it works in theory. But just on my desktop PC, no other device, wow. I tried to run it on my new laptop, but it's so new that it still has the preinstalled OS and there I can't deactivate going to standby when closing the laptop, so while I expected it to add 5000 videos, it instead added 4 and went to standby. But doesn't matter, because it would have failed at about 700 anyway. Every time I try to use this website, I get new problems, but it seems to still be the best option, because everything else just doesn't do anything. This page at least got to 700 before.

Continuing in first comment!

So... I have 5 Raspberry Pi Zeros (no Wifi), one RPI Zero with wifi and one RPI 2 b+. I want to do home automation stuff with them. Any ideas?
I was thinking openhab, my only problem is that the rpi zeros dont have wireless connections.

questions for those hard core lazy geeks, I'd like to try out raspberry pi. what's the most crazy use cases in you mind but yet no way to find time to do it? if I get rid of my laziness, I may do it, no promises😜

!rant

So, I have a Raspberry Pi and I have no idea what to do with it. Any suggestions? I already have a SD Card with retropie.

So, today, I wanted to try setting up a wireguard VPN server on my little raspberry pi at home. I... expected /some/ issues, but what I found dumbfounded me.

1 - I already had the wireguard package from the unstable branch of the main raspbian repo installed... Huh, okay.
2 - Setting up config was extremely easy... Wow, so the rumors were true. Wireguard really is almost dumb-simple.
3 - Failed to create a network interface? Oh, trouble, here it is! So lets see... modprobe wireguard... Nope. Don't have the module? What?
4 - Reconfigure package to rebuild the module - missing kernel headers? Huh... weird

This was the simple stuff... Then I went down the rabbit hole of the Raspberry Pi ecosystem:

1 - There is the Raspberry Pi Bootloader, that is apparently separate from the Kernel itself. And I didn't seem to have any of the standard linux-image-* installed... What? Weird, yet there I was, running a 4.19.42-v7+ kernel...
2 - No kernel and no headers... What... The... Fuck
3 - Okay, so... Lets just... try to install the latest kernel image then? One apt-get install... It downloaded the image, but during package configuration, it failed because... I didn't have... its headers? What? What for? And if it needs them (for whatever reason), why isn't the headers package as a dependency? Ugh, whatever...
4 - Another apt-get install and... Okay, building the initrd image aaaaand...
FAIL
WHAT. What is it this time!?

Oh... Ran... No more space on device? What? Is /boot independent? Of course it is, it has to be, its a bloody different filesystem

Okay, so, lets che-OH MY GOD WTF.

Its just bloody 45 MBs big! The entire /boot is just 45 MBs large. WHY. THE. FUCK.

This was a default raspbian install from I have no idea when. But... Why. Oh WHY would ANYONE pre-configure /boot to be this incredibly tiny!?

No wonder the new init ramdisk couldn't fit in there! Its already used up from 64%!

Thanks, Raspbian Devs, now I gotta reinstall the whole system because, yes, the /boot is, of course, sector 8192. Just far enough from 2048 that there are *some* sectors free - About 3 MBs.

So what did I try? Remove the partition and recreate it from the very beginning. Only... I never tried in in the past, and okay, kernel doesn't like having the partition where its image resides deleted on the fly, it will not give up FDs pointing there or something.

So now, I have a system I cannot reboot, or it will never boot back up :|

Thanks, Raspbian!

I need to get a cheap 1U somewhere or something T.T

i need an adult. I know noone who would understand my worries, so you guys need to be it.

i have a nextcloud running on my raspberry pi. performance is horrible, dont ask, but it works.

i mostly use it to backup the photos of my phone sd card every night when my phone charges. Internally this works good. If i am elseplace it wont for obvious reasons.

In my youthful joy of doom i opened port 443 and forward it to my raspi. I get internet via cable and my ip is pretty much static (it was the same for 10 months). So external access is provided.

Now i thought, its stupid that i cannot sign an ssl certificate cause i dont have a domain. Lets buy domain. But before i do that i did some try runs with duckdns to test the principle.

Some back and forth, it works now. Pretty god, i could even make a cron job on the raspbi to renew (that should work right?). Only problem. randoname.duckdns.org doesnt work internally. Or should not at least.

So i googled a bit and it turns out that my router (a cable fritz!box i bought myself) can be a local network dns. Or cannot. Regardless what i try, it doesnt accept the changed config file.

Now the problem.

It works anyway. randoname.duckdns.org points to my external "static" ip and resolves to that from my internal network..so it works on my phone or laptop. if i traceroute the thing it goes via two hops out and finishes in less than 1ms.

Now to the problem:
I have no fokkin clue why. The expected behaviour would be that it shouldnt work. If i do what i intended todo on pc in the hosts file tracert works correctly, directly pointing to the internal ip.

What i cannot figure out, is it the fritz!box being smart? Is it my ISP being smart?

Reason to rant: i have absolutly NOONE to ask, i know not a single person who would even understand what troubles me. I want to learn, i want to know WHY not just some mindless russian patchwork of "if it works its good enough".

thats depressing.

I don't have any experience in teaching, but I'd venture to say that teaching anything is hard. For most subjects, teaching has been refined over thousands of years to be easier and meaningful. Not CS. As has been mentioned by many people CS is a very new subject when compared to the likes of maths, for example, and education systems haven't been able to cope with it adequately (nor should they be expected to).

That the CS industry is rapidly evolving certainly doesn't help matters, but in reality that shouldn't really be that big of a problem (at least in earlier years of education). The basics of computer systems and programming don't really change that much (please correct me if I'm wrong) and logic stays the same. Even if you learn stuff that's a bit out of date it can still be useful and good lessons should be able to be applied to new technologies and ideas.

Broken computers is a big inconvenience, but a lot of very useful things can be done without a computer, and I should think the situation is a lot better than it was 5 years ago. What I think would be good, instead of trying to use broken computers would be to get students to set up and use a raspberry pi each; you learn about something other than windows, learn how to install an OS and you don't need that much computing power for teaching people computer science.

I think the main problem is a lack of inspiring teachers. Only a very few teachers will be unable to get you through the exams if you put in the effort, but quite a lot of the time students don't put in the effort because they can blame it on the teacher.

My solution would be to try and get as many students into computer science as possible and the rest will follow: more people will become teachers, more will be invested in the subject, more attention will be payed to the curriculum.

That's not to say I don't agree that many of the problems that have been mentioned need to be fixed for CS education to work properly, just that there is no way that I can see to fix them currently without either creating more problems or some very rich person giving a load of money.

This has gone on a lot longer than I expected so I'll stop now.

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!

Long time no see!

I'm thinking about creating a Youtube channel to create some funny dev projects.

The first one is going to be: "Creating the DevOps nightmare", where I'll create a server health-checker to run on my raspberry-pi, and if the checked fails it'll trigger an API to call him with the voice of my boss, saying that if he doesn't fix that, he will be fired.

What do you guys think?

Q).How does one try to understand how or what a programme is in a third world country with no basis of proper infrastructure?

Apart from using raspberry pi which not only requires a person to help yiu understand it but cost a lot.......Something that Completes the circle , from bundling the the hardware with seamless software out of the box and for the fraction of the cost of a raspberry pi

[Open to all sorts of input.....from this thing has no practical use to lets do something]

No internet! I have been without home WiFi for a week now and I can't download big files over my hotspot as it is expensive. I need to download a Raspbian image for my Raspberry Pi but it is ~1 gigabyte. Been needing to get my Raspberry Pi set up to turn it into a server for a site I am currently creating.

Sophomore year starting soon so I'm looking for new project (s) to complete in parallel with the studies.
Some are more design-y and some more backend-y but I recently started getting better at designing so :)

1) Learn some fragment shader stuff. I've always been messing around with graphics and have a game on steam, so I think that's a good idea to be paired with signal processing.

2) Reactive web services. Preferably with spring-boot or vert.x but

3) I would also like to dive into golang (and make some reactive thing with it)

4) WebAssembly seems nice... But I got some concerns

5) exercise making wireframes -> CSS (with some js)

6) I've never really done any real backed work with nodejs, except serving and aot compiling js, or doing gulp tasks

7) Implementing a whole project, or a fraction of it as serverless on aws

* I'm definitely going to use a couple very simple services to make a docker swarm with load balancing, etc, just because I know how everything works but got no practical knowledge

8) Design an esports jersey for the university department I'm in (shouldn't take long)

So what do you guys think? Recommendations are welcome :)

P.S. last year in review:
> A webapp running on a raspberry pi powering a reflex testing game on gpio (java/spring-boot , codename: buttonmasher)
> small Elastic search cluster to monitor some random university servers through kibana dashboards
> laser tracking on wall of *any* colour and variable light conditions via a webcam (opencv) , controlling the mouse pointer, whether you run it against a projector or any wall
> jstrain.herokuapp.com => a small JavaScript powered tool with a DSL to help you train more efficiently without a coach
