I don't understand why every non-technical person who comes to do work in my apartment messes up my fucking router.
The cleaning lady - multiple times knocked the antennas partially off. Like fucking clock work. I don't get it, why is the cleaning lady attracted to my router antennas and why does she need to be so hard on them? Whatever.
The most ridiculous episode was today. And it wasn't the cleaning lady. I had a few people here doing some work today and the woman in charge who was here informed me before that they might have to move the furniture "a little."
I come home, and like a bad omen, the plastic parts on BOTH my router antennas are missing. Completely gone. It's just the the wires. Now, the router still works fine in my tiny apartment, but it is a fancy Asus router (I learned the hard way not to buy cheap routers) and I'd like it to not have fucking wires as antennas.
I email the woman (paraphrased):
Me: hey, it seems the antennas got knocked off my router, do you have any idea where they might have went?
Her: Apologies if we didn't put everything back (no shit you didn't, that's why I've had to email you). If we knocked the antennas off the router (fucking "if"???? I literally just told you in my email that they were knocked off) , they are probably somewhere by the window on the floor (they weren't).
And I still haven't found them. Why the fuck do these people seemingly attack my router? I can't figure out what it is about it. You would think people would be more careful around electronics but naaah. Anyway, going to go keep looking for my router antennas.

I fucking hate CNET already. I mean who likes a website which autoplays a video everytime you visit them, with 200% volume.
But this time, I am just so fucking annoyed. Here is the title of an article:
"iPhone 8, X's wireless charging is a game changer for Android"
And the subtitle:
"When it comes to Apple, plenty of Android phone makers are monkey see, monkey do."
FUck you motherfucker. "Monkey see, monkey do". Are you fucking kidding me you cunt?
Remeber your 3D touch bullshit? Your fucking wireless charging will be bullshit too.
"the rest of the phone users make do with messy cables."
Maybe you're a fucking imbecile who doesn't know how to manage simple cables and ends up with broken wires.
You know who looks like a monkey? Some apple users who uses that shitty looking wireless earphone, which looks like monkey's dick you asshole.
Fuck off!18 -
Dells XPS are made of magic. [long story, major fuckup, 10k+ damages]
It all started in December. One morning I was late to work, drove there as fast as possible. (I live like 3 minutes away so me being late really meant *late*) Parked my car in a secluded car park, grabbed my backpack and ran to work. The car park is like 100 meters away from work so I took my feet into my hands and ran. Next thing I know my heels loose all grip while I go down a small slope and I drop on my back full force. On a sharp edged stone. With only my 1700$ XPS in it. Fuck.
I paniced, but got up and ran to work. I checked on the notebook, praying it would boot. It booted! Holy shit. I flipped the notebook and saw two small dents in the aluminum shell. I was thorougly impressed. I later discovered that it left a small shadow on the display, but given what a hit that was (I am not exactly a lightweight), impressive would be a massive understatement.
Fast forward to February, I am weighing my options to get the screen replaced maybe, as damage on my hardware (even if neglectable) triggers some sort of OCD and makes me feel bad 24/7. Also my laptop tends to shut off from time to time, looked into the Event Viewer and saw kernel panic. I figured that the battery probably still took a hit and that it drops voltage from time to time and the kernel assumes a critical situation, thus shutting off.
It stayed quite snowy in Austria up until March, so occasional snowing wasn't rare. Got out of work one day, saw it snowed a bit. Whatever. I had my moms car at the time, so I tried if it would slide a bit if I donut on the now (5pm) empty parking space. Nothing. Drove done a small hill, ABS triangle lit up red (board computer can't outbalance the snow). I drove out to the main street where everything was salted and drove along towards my house. Took a turn into my street, accelerated for a bit and then went off the gas so the car would smoothly drive along with the speed slowly degrading. So I went off the gas and noticed I was a bit to the right, no wonder, centrifugal forces.
*steers left*
"Huh seems like I need a bit more"
*car still doesnt move much*
"What the- go to the left!"
*steers left hard*
"Fuck that wall is coming closer"
*Breaks*
*car doesnt break*
"FUCK FUCK FUCK FUCK!!!"
Everything got quiet in seconds, me waking up to an open airbag, ripped pants, a hurting wrist, the radio somewhere on the ground and fumes that smellt like burning wires. I grabbed my backpack that was now somewhere on the floor instead of on the seat and ran outside, tears in my eyes and the phone on my ear calling my mom. I walked inside as she walked outside, hearing a weeping scream that I haven't heard from her since I am alive. While walking inside I noticed my backpack was wet on the bottom, my 2 litre water jug shattered when my backpack hit the dashboard. I tried to stay calm and act rational, knowing that every second counts when It comes to water damage. I hastely searched for some rice and a bag to put my laptop into, stuffed the bag with both and went outside. The car was totaled, my mom pissed and crying. And I was in shock, sad, angry and hurting.
I kept the laptop on my heater for a few days, bagged in rice. I dared to try a boot after a while and you wont believe me, it fucking booted. Even the keyboard backlight worked, just the screen was obviously broken in the back (no color distortion or bad pixel rows though!!) and the aluminum shell had a dent on the front. I talked with Dell Support a few days later, asking if it would be ok to open the XPS up so I could drain all of the water. She said yes thats fine, as long as I dont touch anything or screw around with it.
She said I can send it in and get it checked, but the pickup and analysis will cost 150$ and I can go from there.
I sent it in and estimated that, because battery, screen and other things probably needed changing, it will be around 900$.
Got a call a few weeks later:
"Hello beggarboy, the repair team reported back to us and said that they will have to replace everything, which will be 1700$."
"Fuck... Buying a new one is cheaper.."
"Yeah I know I am sorry about that, I can offer you a voucher so you can buy a new one for 250$ off if you would prefer that"
"Sorry but I will need some time to consider"
"I understand."
The agent clearly noticed I was bummed about it.
After going back and forth what to do I got another call a few days later.
"Hello beggarboy, we talked a few days ago. I have good news"
"Hello, yes, speak up?"
"I was able to get a special offer for you after putting in a few words..."
The next thing she said seemed unreal to me.
She was able to cut 600$ (!!!), making the new offer 1100$, instead of 1700$ or a new one for 1500$. I figured the reason she probably did that was because I am always very polite with support members. Always.
My XPS is back and healty again.
Thank you for taking the time to read this.

Seriously, just how exponentially fucked did this world just become.
I'm pretty sure that this post's format would be more tailored towards devrant.com (well, hereby). But I wanted to vent about it, here, now.
A copy of this post is available at https://facebook.com/irc.condor/....
Just the other day the EU Parliament accepted that widely disapproved copyright directive - article 11 and 13. Despite direct lobbying on our end. And by whom? Not by young, competent parties like the Pirates. No, instead the old fucks from the conservative party had their say, driven by nothing but incompetence and lobbying from label companies.
Then the whole ordeal with the Master/slave issue in Python started. Again met with significant outrage - and again approved while completely ignoring the voices of everyone else. I even ended up making a fork for it at https://github.com/toloveru/cpython. Please star it to show your support for the cause. It is made in response to a denied revert at https://github.com/python/cpython/....
And then we had the issue of Linus Torvalds leaving the Linux project. The single most important person when it comes to Linux.. and he left, just because he admits to be an asshole - something which apparently needs to be changed?! Dude, be a fucking asshole! That's what made the Linux kernel great in the first place!!! Yet even you give in to those SJW cunts?!!
AND THEN... If Linus' disappearance wasn't enough already, core developer at the LLVM project Rafael Avila de Espindola leaves the project as well, because of an influx of SJW's and political correctness.
It started with feminism in the past century. Now it's superiority and pink-/blue-haired warriors going for OUR SUPERIORITY AND UNIQUENESS and being offended by whatever they can possibly get offended with. Fucking cunts they are. You heard that right. FUCKING CUNTS!!! Because yeah, in my house I swear like that. Anyone who doesn't like that can fuck right off.
But what good does my criticism towards all this still serve.. nothing, does it. Those live wires that I've avoided touching for so long.. they suddenly don't feel all that repulsive anymore. Thanks society!24 -
*sees that the high voltage generator kit got delivered today*
Cool, let's build this thing and integrate it into my old bugzapper! Mosquitos beware 😈
*starts building the kit, all is going very well*
Oh wow, isn't it Monday? But it's taking only 15 minutes of soldering and everything goes super smooth.. what divine power is giving me such good luck?
Alright, last thing, the transformer and then this circuit is done!!!
*solders in the transformer without realizing that the wires are coated, and the solder isn't protruding through*
Fuck. Time to desolder this shit and blast the wires with my lighter to flash that coating right off!
*engages solder pump and solder goes off extremely easily, because it only adhered to the pad*
*takes off transformer*
Me: "Nnngh..!!! Get off you piece of junk!!!"
Transformer: "Hmph!! I will stay in here no matter what!"
Me: "Get the fuck off already!!! 😡"
Transformer: *leads break off* "Alright, but these leads stay here!!!"
Me: "MotherFUCKER!!!"
Yep, it's Monday after all.

An entire night I've spent on this shit.. preparing wires, soldering them on the motherboard, and finally connecting everything up to current meters, my PC's USB port and a lithium cell from my old Doogee phone that I still had laying around. All in the hopes to get an adb shell. But all in vain.. the turd doesn't even want to boot up. What a fantastic waste of time 😑
(Apologies for the terrible picture quality btw, this tablet's camera is absolute garbage)

Fuck all those shitdesigns that interface with their LCD using flat graphite cables!
USE FUCKING COPPER WIRES ALREADY!!! At least those things can take a small fucking tug of gravity during disassembly, unlike that micron-thick graphite junk which fractures even more easily than my goddamn toe did!!!
And as mentioned on Hackaday (https://hackaday.com/2012/09/...), repairing it is hell. How much does it cost to make a decent copper wire.. I can buy those things for like 20 cents from AliExpress, so don't tell me motherfuckturer that you can't. And these copper ribbon wires last on ya, AND can be repaired with a simple soldering job. Unlike this FUCKING GARBAGE!!!7 -
I have this little hobby project going on for a while now, and I thought it's worth sharing. Now at first blush this might seem like just another screenshot with neofetch.. but this thing has quite the story to tell. This laptop is no less than 17 years old.
So, a Compaq nx7010, a business laptop from 2004. It has had plenty of software and hardware mods alike. Let's start with the software.
It's running run-off-the-mill Debian 9, with a custom kernel. The reason why it's running that version of Debian is because of bugs in the network driver (ipw2200) in Debian 10, causing it to disconnect after a day or so. Less of an issue in Debian 9, and seemingly fixed by upgrading the kernel to a custom one. And the kernel is actually one of the things where you can save heaps of space when you do it yourself. The kernel package itself is 8.4MB for this one. The headers are 7.4MB. The stock kernels on the other hand (4.19 at downstream revisions 9, 10 and 13) took up a whole GB of space combined. That is how much I've been able to remove, even from headless systems. The stock kernels are incredibly bloated for what they are.
Other than that, most of the data storage is done through NFS over WiFi, which is actually faster than what is inside this laptop (a CF card which I will get to later).
Now let's talk hardware. And at age 17, you can imagine that it has seen quite a bit of maintenance there. The easiest mod is probably the flash mod. These old laptops use IDE for storage rather than SATA. Now the nice thing about IDE is that it actually lives on to this very day, in CF cards. The pinout is exactly the same. So you can use passive IDE-CF adapters and plug in a CF card. Easy!
The next thing I want to talk about is the battery. And um.. why that one is a bad idea to mod. Finding replacements for such old hardware.. good luck with that. So your other option is something called recelling, where you disassemble the battery and, well, replace the cells. The problem is that those battery packs are built like tanks and the disassembly will likely result in a broken battery housing (which you'll still need). Also the controllers inside those battery packs are either too smart or too stupid to play nicely with new cells. On that laptop at least, the new cells still had a perceived capacity of the old ones, while obviously the voltage on the cells themselves didn't change at all. The laptop thought the batteries were done for, despite still being chock full of juice. Then I tried to recalibrate them in the BIOS and fried the battery controller. Do not try to recell the battery, unless you have a spare already. The controllers and battery housings are complete and utter dogshit.
Next up is the display backlight. Originally this laptop used to use a CCFL backlight, which is a tiny tube that is driven at around 2000 volts. To its controller go either 7, 6, 4 or 3 wires, which are all related and I will get to. Signs of it dying are redshift, and eventually it going out until you close the lid and open it up again. The reason for it is that the voltage required to keep that CCFL "excited" rises over time, beyond what the controller can do.
So, 7-pin configuration is 2x VCC (12V), 2x enable (on or off), 1x adjust (analog brightness), and 2x ground. 6-pin gets rid of 1 enable line. Those are the configurations you'll find in CCFL. Then came LED lighting which required much less power to run. So the 4-pin configuration gets rid of a VCC and a ground line. And finally you have the 3-pin configuration which gets rid of the adjust line, and you can just short it to the enable line.
There are some other mods but I'm running out of characters. Why am I telling you all this? The reason is that this laptop doesn't feel any different to use than the ThinkPad x220 and IdeaPad Y700 I have on my desk (with 6c12t, 32G of RAM, ~1TB of SSDs and 2TB HDDs). A hefty setup compared to a very dated one, yet they feel the same. It can do web browsing, I can chat on Telegram with it, and I can do programming on it. So, if you're looking for a hobby project, maybe some kind of restrictions on your hardware to spark that creativity that makes code better, I can highly recommend it. I think I'm almost done with this project, and it was heaps of fun :D

Very funny/random/weird partly non-dev related story that happened today.
We're selling our coffee machine at work since the coffee is gross.
Someone wants to buy it and wants it to be sent.
Coworker: just the general way through a package?
Other coworker: hmm yeah through post is fine
Me: POSTAL PIDGIN
other colleague: BY PENGUIN
Another colleague: BY LIKE 100 PENGUINS FLYING THAT THING THROUGH THE AIR WITH LIKE WIRES ATTACHED TO IT
Me: just hold on for a second and imagine this graphically...
Colleagues: damn that would be fucking genius xD
Yeah we're quite random 😆30 -
Christmas lights were blinking randomly IN SECTIONS without any sort of "control brick", just with a plain wall plug and TWO wires coming out of it.
In this house we obey the laws of physics, I immediately called magic on this and started digging. I found out that was like five chains of lights wired in parallel, and every chain contained one special lamp that had a thin plate of some thermal-sensitive material inside. It heats up which makes it go straight, thus breaking its chain until it cools down enough to curl again and make the contacts touch.
Brilliant and really cheap way of making randomly blinking Christmas lights without any kind of controller, with just two wires and some physics. That's what I call "nocode".

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!!!5 -
Soooo, i'm assigned to finish a half made prototype of a production line functional test platform.
1 - Some wires were faulty so someone decided to change them.
2 - wild shortcut appears *music fades, screen goes black*
3 - now i have to fix the prototype
4 - Devil's voice whispers on my ear *welcome to heeeeellllllll*

Me: *starts to get into electronics*
Me: *unplugs a few wires while building a project*
Me: Shit, actually, didn't want to unplug those. No worries.
Me: *instinctively reaches for the nonexistent Ctrl-Z*
Me: Oh, that's right. My actions have consequences in the real world.5 -
Just thought I'd share my current project: Taking an old ISA sound card I got off eBay and wiring it up to an Arduino to control its OPL3 synth from a MIDI keyboard. I have it mostly working now.
No intention to play audio samples, so I've not bothered with any of the DMA stuff - just MIDI (MPU-401 UART) and OPL3.
It has involved learning the pinout of the ISA bus connectors, figuring out which ones are actually used for this card, ignoring the standards a little (hello, amplifier chip that is wired up to the +12V line but which still happily works at +5V...)
Most of the wires going to it are for each bit of the 16-bit address and 8-bit data. Using a couple of shift registers for the address, and a universal shift register for the data. Wrote some fairly primitive ISA bus read/write code, but it was really slow. Eventually found out about SPI and re-wrote the code to use that and it became very fast. Had trouble with some timings, fixed those.
The card is an ISA Plug and Play card, meaning before I could use it I had to tell it what resources to use. Linux driver code and some reverse-engineering of the official Windows/DOS drivers got me past this stage.
Wired up IRQ 5 to an Arduino interrupt to deal with incoming MIDI data, with a routine that buffers it. Ran into trouble with the interrupt happening during I/O and needing to do some I/O inside the handler and had to set a flag to decide whether to disable/re-enable interrupts during I/O.
It looks like total chaos, but the various wires going across the breadboard are mainly to make it easier to deal with the 16-bit address and 8-bit data lines. The LEDs were initially used to check what addresses/data were being sent, but now only one of them is connected and indicates when the interrupt handler is executing.
There's still a lot to do after that though - MIDI and OPL3 are two completely different things so I had to write some code to manage the different "channels" of the OPL3 chip. I have it playing multiple notes at the same time but need to make it able to control the various settings over MIDI. Eventually I might add some physical controls to it and get a PCB made.
The fun part is, I only vaguely know what I'm doing with the electronics side of this. I didn't know what a "shift register" was before this project, nor anything about the workings of the ISA bus. I knew a bit about MIDI (both the protocol and generally how the MPU-401 UART works) along with the operation of a sound card from a driver/software perspective, but everything else is pretty new to me.
As a useful little extra, I made some "fake" components that I can build the software against on a PC, to run some tests before uploading it to the Arduino (mostly just prints out the addresses it is going to try and write to).

Just disassembled 2 €5 desk fans because they were shit.. and so is their design apparently.
What I found inside was actually surprisingly simple.. a toddler could build it. It's just a DC motor, a 3PDT switch, DC barrel connector, some wires and screws to hold stuff in place. Oh and the plastic thingie with the fan blades, as well as the USB cable of course.
5 fucking euros. The combined cost of the components would be less than 3, certified motherfuckturers. Time to build it, injection moulding, transportation, sure.. but still.
And if you think that being salty about €5 is cheap shittalk, expand that to every fucking piece of electronics that doesn't cost a small fortune.. at all price ranges. Could be radios, alarm clocks, heck even phones. Shit's way too expensive for what it's worth. Perhaps because so many people in the industry are just here for a quick buck.. motherfuckers 😒
Anyway, back to the design.. the hole in the fan blade thingie is supposed to get the motor's shaft shafted in, to turn the blades. I'd use glue there.. but not these designers. They just shove it in and hope that friction takes care of everything. And one of the fan blade modules' hole was so wide that inserting the motor is like throwing a sausage down the hallway. No contact at all! Make it tight already like the Chinese designer's glory-...
Nah let's not get into Chinese tightness just yet.
Oh and also a resistor for slow mode. Consumes just as much power except the fan turns slower. Because fuck efficiency, right?
Goddammit, next time I'm just gonna build my own again.. at least that wouldn't be a certified piece of shit 😑

I fucking hate holidays. Every goddamn time when it's a holiday, that's when I need to go to the store and get something, only to find out that they're closed. And what for.. holidays are - to me at least - no more than an excuse for people to not go to work for the day.
So, now I ran out of booze, and can't continue developing and testing my breathalyzer until Monday.
Then it hit me.. what if I take all my Arduino equipment (laptop, jumper wires, ...) to the café and deploy my build environment on a table there?
Eh, no no no. I don't want some idiot to come up to me saying "YOU EVIL HEKORMAN!!!" and have to explain that just like when you call a banker who's working with the money vaults a thief, it's wrong to call someone that's developing shit an evil hacker.. one should strive to not throw mindless accusations out of unknowingness. Not that I'm a good example of that though. But still.
It's probably that or some stupid bitch coming up to me asking to hack her boyfriend's Phasebuk.. that said, that could probably be an opportunity to get in her pants. But then, I don't wanna insert my meat in an idiot like that... ._.
So, no booze it is then? Thanks national holidays!
"Ok Google, remind me every day before a holiday because I really couldn't care less about them!!"16 -
*receives an old business laptop as payment for refurbishing another one*
Hmm, this thing doesn't have a charger with it.. looks like it's taking 18.5V.. my HP laptop's charger supplies that but its barrel connector doesn't fit 🤔
Regular users: oh dear now I have to buy a charger with a fitting connector for this.. where do I even start?!
Me: Well I guess I could just remove the charging port and solder some wires straight into the board instead 🤔
But that voltage.. my HP laptop's charger is still in use and I don't really want to fuck around with that one.
Regular users: oh dear oh dear, shouldn't I just throw this laptop away?
Me: well I guess that I could just use one of the rails of my upgraded lab bench power supply for it?
Lab electronics saving the day, every day, time and time again.. fuck yeah 😎6 -

Four hours of work.
You think you write spaghetti code? I write spaghetti wires.
H-Bridge dual motor tester for stepper motors.
Speed is controled by pot.
H-bride are L293D.
My third board, and the first that won't go to the trash.
Question. With the baterry off the motor continues spinning with the 5v from arduino.
My question is, is the L293D suposed to do that? Or do I have a short circuit somewhere that is giving power to the motor? Meaning it can burn the arduino.
Runs a 12v stepper from a CD-Rom driver perfectly at 5v from the arduino and actually starts to act strange when I turn the 12v on. (maby the circuit it's adding 12v + 5v?)

Where I work we develop drivers and command-line software for embedded systems. The contracts we have with our customers tend to be in the £100k-£500k range and are usually completed in 6 - 9 months; our team is made up of 20 developers. You would think that it would be worthwhile investing in the department. But no, instead we have to deal with >10 year old build servers on their last legs; limited numbers of development boards with wires soldered on so that we can keep up with new board revisions; no room for R&D into new products; and to top it all off, not one of the executives has a laptop on par with the placement students in the next department. It's like the company is trying to kill the department, we've seen our staffing dwindle with no new graduate (or higher) positions being made available in the last 3 years while we've lost at least 5 people to other places. I just don't get it!3

I just completed my first live soldering project...
Converted my son's mobile (dangly plush animals and music not cell phone) from using 4 X C batteries (LR14) to using an AC-DC transformer
I hardwired it at 6v and it worked, and I didn't burn myself, and I cut a little gap for the wire and it's really snug so the solder is under no tension.
I tinned the wires beforehand like I knew what I was doing and for once I didn't fuck it up!
Sorry, just had to tell someone. The wife's asleep and she just won't understand.5 -
So I just received this second DSP5005 DC-DC programmable power supply. Time to make an enclosure for the thing!! 3 power supplies totaling at around 1kW, and 2 variables connected to the 50V 10A one, through external banana wires (I want all of this to be modular). No biggie, take measurements for the AC-DC supplies, add in the variables on the front, and cut it out.
So, I went and did just that. Now my 500W (50V 10A) supply is a bit larger than the others, and it's got a fan. So I figured, well then probably my 24V 8.3A (200W) and 12V 15A (180W) supplies could use some cooling as well. But how am I going to achieve passive cooling without a spacing between the supplies?! So I thought of some spacer design. It had to be out of wood, and I had some 4mm MDF and some IKEA parts around. So, 4mm MDF for the plate and 8mm wood spacers from IKEA for the spacing. And some super glue to hold it all together.
Weighing my power supplies against a 1l bottle of milk, it seems like my power supplies are ~500g. Great, so the top spacer would take 500g and the bottom one 1kg + the weight of the top spacer.
I ended up building one plate with 6 spacers in it yesterday, until I got too tired. Then I placed my entire weight against it, 20kg at least. It didn't budge. Pretty good for something that's only designed to withstand a 1kg load!!
So, I made something good with only a 10x18cm piece of MDF, some garbage from IKEA, and most importantly a bit of a brain. Something that can handle 20x its designed load no problem. Manufacturers, is it really right to produce shit when I can beat your manufacturing processes big time without an assembly line?!5 -
Every time..
Every single time!
All day long the hairy one is nowhere to be found. But as soon as you put some tech and/or wires on the bed - be sure she'll find it to be the best sleeping spot in less than a minute.
Literally a techno-cat.

I wanted to play Pirates under DOS back then, but it didn't have the left-handed mouse button switch like Windows.
So I opened the mouse, scratched the PCB button lines away, soldered wires cross-over, and had a left-handed mouse also under DOS.3 -
When working with hardware some mistakes can be literally painful. Thankfully this was all during undergrad and I'm only around computer hardware now lol.
>Misprogrammed a software kill switch so a sensor that should not have been sending data was actually sending data which caused the system to activate a piston that went WHAM! into the face of a teammate working on replacing some part of it...

Is the software at your company so bad that it's a miracle that anything works?
Does it feel like this colossal pile of broken electronics from the past 30 years duct taped together and patched with multiple tiers of adapters, wires spliced together with scotch tape, and someone on stand by with a fire extinguisher?
Do you feel like getting your product to work is like how we used to get things to work back in the eighties? Not just turning things off and on again, but things like hitting the tv to make it work again, blowing into cartridges, and the feeling of pulling on the starting cord on a gas powered mower over and over again to no avail?
That is exactly what my company's codebase is. A huge amorphous, heterogenous pile of shit that somehow works and occasionally has to be massaged to make it work again. Fuck my life.3 -
I went to the tech department at my school to get some solder and a few offcuts of wire, but some generous person gave me 6 raspberry pi's that he didn't need anymore! But that's not all, he also gave me 5 rangefinder sensors, 4 motors, a 4 digit 7segment display, a couple of sd cards, a few other various sensors, and some wires
Oh, and I got my solder, too :)5 -
I've never been a fan of "wireless" technologies.
Whether it's a keyboard, mouse, gamepad. Nope none of it. The latency, need to change batteries (if any), chances of putting the accessories in places other than your gaming desk thus creating clutter around your house.
And earphones, HOLY CRAP. You cannot convince me that any sort of Bluetooth earphones have better sound quality than my wired 3.5mm Sennheiser earphones.
I'd rather take wires and get quality content consumption over Bluetooth/Wireless for a little "convenience".13 -
I haven't ranted for today, but I figured that I'd post a summary.
A public diary of sorts.. devRant is amazing, it even allows me to post the stuff that I'd otherwise put on a piece of paper and probably discard over time. And with keyboard support at that <3
Today has been a productive day for me. Laptop got restored with a "pacman -Syu" over a Bluetooth mobile data tethering from my phone, said phone got upgraded to an unofficial Android 9 (Pie) thanks to a comment from @undef, etc.
I've also made myself a reliable USB extension cord to be able to extend the 20-30cm USB-A male to USB-C male cord that Huawei delivered with my Nexus 6P. The USB-C to USB-C cord that allows for fast charging is unreliable.. ordered some USB-C plugs for that, in order to make some high power wire with that when they arrive.
So that plug I've made.. USB-A male to USB-A female, in which my short USB-C to USB-A wire can plug in. It's a 1M wire, with 18AWG wire for its power lines and 28AWG wires for its data lines. The 18AWG power lines can carry up to 10A of current, while the 28AWG lines can carry up to 1A. All wires were made into 1M pieces. These resulted in a very low impedance path for all of them, my multimeter measured no more than 200 milliohms across them, though I'll have to verify and finetune that on my oscilloscope with 4-wire measurement.
So the wire was good. Easy too, I just had to look up the pinout and replicate that on the male part.
That's where the rant part comes in.. in fact I've got quite uncomfortable with sentences that don't include at least one swear word at this point. All hail to devRant for allowing me to put them out there without guilt.. it changed my very mind <3
Microshaft WanBLowS.
I've tried to plug my DIY extension cord into it, and plugged my phone and some USB stick into it of which I've completely forgot the filesystem. Windows certainly doesn't support it.. turns out that it was LUKS. More about that later.
Windows returned that it didn't support either of them, due to "malfunctioning at the USB device". So I went ahead and plugged in my phone directly.. works without a problem. Then I went ahead and troubleshooted the wire I've just made with a multimeter, to check for shorts.. none at all.
At that point I suspected that WanBLowS was the issue, so I booted up my (at the time) problematic Arch laptop and did the exact same thing there, testing that USB stick and my phone there by plugging it through the extension wire. Shit just worked like that. The USB stick was a LUKS medium and apparently a clone of my SanDisk rootfs that I'm storing my Arch Linux on my laptop at at the time.. an unfinished migration project (SanDisk is unstable, my other DM sticks are quite stable). The USB stick consumed about 20mA so no big deal for any USB controller. The phone consumed about 500mA (which is standard USB 2.0 so no surprise) and worked fine as well.. although the HP laptop dropped the voltage to ~4.8V like that, unlike 5.1V which is nominal for USB. Still worked without a problem.
So clearly Windows is the problem here, and this provides me one more reason to hate that piece of shit OS. Windows lovers may say that it's an issue with my particular hardware, which maybe it is. I've done the Windows plugging solely through a USB 3.0 hub, which was plugged into a USB 3.0 port on the host. Now USB 3.0 is supposed to be able to carry up to 1A rather than 500mA, so I expect all the components in there to be beefier. I've also tested the hub as part of a review, and it can carry about 1A no problem, although it seems like its supply lines aren't shorted to VCC on the host, like a sensible hub would. Instead I suspect that it's going through the hub's controller.
Regardless, this is clearly a bad design. One of the USB data lines is biased to ~3.3V if memory serves me right, while the other is biased to 300mV. The latter could impose a problem.. but again, the current path was of a very low impedance of 200milliohms at most. Meanwhile the direct connection that omits the ~200ohm extension wire worked just fine. Even 300mV wouldn't degrade significantly over such a resistance. So this is most likely a Windows problem.
That aside, the extension cord works fine in Linux. So I've used that as a charging connection while upgrading my Arch laptop (which as you may know has internet issues at the time) over Bluetooth, through a shared BNEP connection (Bluetooth tethering) from my phone. Mobile data since I didn't set up my WiFi in this new Pie ROM yet. Worked fine, fixed my WiFi. Currently it's back in my network as my fully-fledged development host. So that way I'll be able to work again on @Floydian's LinkHub repository. My laptop's the only one who currently holds the private key for signing commits for git$(rm -rf ~/*)@nixmagic.com, hence why my development has been impeded. My tablet doesn't have them. Guess I'll commit somewhere tomorrow.
(looks like my rant is too long, continue in comments)3 -
My wife's phone started having power button issues. Then it broke completely with spastic random presses, causing the phone to boot loop. It's a 3 year old Nexus 5 so I was mostly concerned with backing things up, not rescuing it.
Cleaning didn't work, tapping the switch didn't work. This hack worked.
Backup complete.

*The Fearless Leader*
I get a call to check up on a robot that has been exceeding weight limits at certain points of its movement (Crashing). As I get to the pendant (robo-game controller thingy I like to call it) and look over the alerts and warnings I notice some oil around the main power box of the Robot.... Nothing around this has oil.. so I start looking around and it turns out that the issue wasn’t a crash at all! It was an oily shorted out wire that kept sparking mad heavy when that servo was called on.. causing a large servo failure that required a full restart of the power box. I called our fearless leader and showed him only to find out that there was a motor leaking oil from the electrical end... My fearless leader runs both the Maintenance and Robotics department. When the motor was eventually fixed we overheard the technicians say that our fearless leader knew about this a week ago and decided to leave it that way.... with oil... coming out of an electrical cable..... *sigh* well Anyway after all the wires were fixed and motors changed. He comes up to me and says that he can’t believe that I didn’t call maintenance and fill a report on negligence of technicians for failing preventative maintenance....
I lost my cool a little, firstly that’s not my job, I’m literally one of the lowest ranking here. I called my next in command to figure out what I should do. Secondly the technicians told me that you told them to leave it like that! So if this place caught on fire this would have been on you!
Later I found out that he was trying to fire a technician and wanted me to do the dirty work.. I’m not going to be the reason another man loses the means for him to feed his family. The technician is a pretty cool and fair guy too!
Our fearless leader was a forklift driver and has no experience in robotics or maintenance... I don’t know how this happens or even why but all I know is this man is running both departments to the ground and management loves him.....1 -
LabVIEW.
Because WHY THE ACTUAL FUCK should you want to use a visual programming language in a professional environment and pay for it.
(Other than: the manufacturer of your measurement device/power supply/electronic load/etc. has already provided a LabVIEW module so you just have, you know, 'click' your program together and be done.
No, we won't give you the documentation on how to do it properly without that piece of crap or even give you code snippets.
(If you don't feel the urge to shoot yourself in the foot, you have obviously too much time on your hands and could simply be reading the interface definitions for that particular interface. At least it's standardized, d'uh.)
Oh, and you want a lightweight application? Here comes the runtime environment! A big clunky ... thing you'll need now to start up even a simple measure-and-log-data-thing.
Well, OK, it works for the occasional Measure-and-Log-Thing. If you don't need the data too fast.
If you want to do something a bit more complex, knock yourself out, but don't ask me to debug it for you afterwards because that colourful entanglement of wires and connections and blocks is a DAMN HUGE MESS and trying to understand how it works feels like defusing a bomb in a shitty action movie.)
Never again.5 -
Fffffuuuucccckkkkkkkkkk!!
My team and I had a presentation scheduled and we worked on it for more than a month.
A bloody fucking month long preparation.
We went through multiple reviews with stakeholders which weren't necessary and no other team does.
I put on some music to lift up my energy levels while I waited anxiously.
Show time.
We have one of the largest city festival going on this week.
The community in neighbouring building started reciting prayers out loud on a PA system just when the presentation began.
~40 folks and me struggling on video to not lose my cool and fuck my luck, I went nervous because I couldn't focus.
That's when my big boss pointed out that there some background noise and I had to explain it to them.
My very first presence and I forgot to even introduce myself. What a nut head I am.
I am annoyed and angry at myself. I perform well impromptu over planned and preparedness.
Thankfully my team mate who talks a lot and my designer, handled things well and saved the day.
Massive respect for them and kick in nuts for me.
Uuugggghhh!!
Also my neighbour is renovating his entire house and since I am using it as my workspace, I literally sit in between junk and cement and wires all around.
What a messy wasted day it was.19 -
You do know that "why do I need you if I can copy-paste code from SO?" joke floating around, right? Today I had a real-life situation perfectly illustrating it.
So I bought a set of parking sensors. Cheap ones, from AliExpress. Prolly the cheapest ones I could find. Installed them w/ engine turned off. All seemed fine. Cleaned it all up, got ready to go, started the engine and beeeep beeep beeepeeeeep beepp ..... beeeeeeeeep.
fuck.
Tried unplugging/replugging them one-by-one to find the faulty one. Nada. Apparently they all were false-alarming. They must all be bad, bcz they seem to work well w/ engine turned off (ignition on) and only false-alarm when engine is on.
Allright, I'll get a new set next weekend, a more expensive one and replace them again.
There goes my €20 and another week basically w/o parking sensors (car length is >5 meters, so sensors do help a lot).
Today I spend a few hours removing my rear bumper again, replacint all the sensors, wiring, etc. Tests show promising results - all sensors seem OK even w/ engine on! Close it all up, start a car again and.... beeep bep bep beeep beeee..eeeeppp.
MOTHER FUCK!
Another 30min-hour goes by while looking for a possible culprit. And I found it. The fix could did not take longer than 5 seconds. Apparently a wire feedint the sensors' controller was too close to sensors' wires. All I had to do is to push that wire a lil further from the controller with my index finger.
I could have saved €30, a week of time, half a day of work if I only knew what wire to [literally] poke.

This kid on the tape is me. I'm not even two years old there and I'm already messing around with wires.

My godmother asked me to repair her PC... so when opening the case i realized that her "shady"(improvised wires) case fan was not working... so i tried to connect its molex wire to the psu, and realized i neded an wire adaptor because the psu could not support that fan(only had one molex, female, not male and female), but I gave it a try... long story short... I SHORT-CIRCUITED THE PC...(but it restarted after 10 minutes of me dying of fear that i destroyed her pc...)6

was trying to present a project to an audience.
Apple VGA adapter got jammed.
my friend was a little too strong in pulling it out and the adapter wires got ripped out.
i see hot glue on the parts where the output wires connect to the circuit board.
yes! hot glue! now you know why it came out so easily!
i think you guys can imagine what happened to my presentation..
Thanks Apple!

How lawyers fuck up technology!
I rented a car today, given that I don't want to go by train currently. That was some VW Golf, and it had a lane assist which can't decide whether to be helpful or obnoxious:
Either I kept the steering wheel and still steered myself, in which case the lane assist's actions made the steering feel somewhat wobbly. Initially, I suspected a worn out control arm bearing, but that's a long term damage in aging cars, not in new ones.
Or I just rested my hands on my upper legs, as I usually do (palms facing upwards and holding the wheel lightly), then the lane assist worked by itself. It was even smart enough to deactivate itself upon blinking before changing lanes.
However, it complained after about 15 seconds that I didn't steer. I said, shut up and do your job. The warning intensified, and I said, fuck you. Then it initiated some stutter braking to wake me up. Annoying like a reincarnation of Clippy.
I ended up giving the steering wheel a slight tip to the right every 15, 20 seconds just to let the lane assist know I was still there, relying on the lane assist to correct it again. On a long trip, I would have had to deactivate that crap.
Obviously, the VW engineers did their job, but the legal department feared law suits should anything go wrong and ruined the feature!
What was also annoying is that there is no real hand brake anymore in many modern cars. Sucks when pulling off against a hill. Plus that at red traffic lights, I usually put the gear out (manual transmission) and pull the hand brake instead of keeping my foot on the clutch. That's not the same with this pseudo hand brake!
(In case you wonder why anyone would do that:
it's an anachronism that avoids lengthening the clutch wires, decades after cars switched to hydraulics.)12 -
Fuck. The entire day to do this shit.
The screen was my first experiment, but because of a bad module (i2c) it didn't worked.
Today I finnaly got it to work.
Starting making everything almost like in the picture, everything mounted (and lots of black hot glue, no wires showing...
Didn't work.
One hour breaking everything apart without damaging the screen... Was a loose wire.
Started again... Didn't work...
The pot is also damaged, sometimes it works, others need to turn it hard.
New pot.
New set of wires.
Soldering everything right, testing all wires so no mistakes this time... But it takes so longgggg... Making everything in modules this time (to reuse without having to sordering again. And finally... It works.
By this time I should have 3 or 4 learning projects finish (I really wanted the screen to adapt all output in text, no serial, no blinking less, everything in modules, code prepared so, when I get my 40+ packages from China I already have a prototype tester ready.
10 hours... Fuck I'm really addicted, or else I would just solder everything together :D

This isn't about dev, but is related as it was one of my first times seeing how tech could be abused or used in a creative way.
When I was a kid doorbell ditching was a thing. Also, flashing was a thing. Dudes would be naked in a trench coat and flash random people. The 80s was a strange time.
Anyway, my brothers liked to pull pranks. So they took apart a flashlight and mounted a switch into some wires to hold in their hand. They wore a trench coat, had all their clothes on, but wired the light part of the flashlight to their belt at about crotch level.
Then they went to houses at night, rang the doorbell. When people opened the door they flung open their trench coat and blinked the flash light a couple of times and ran away. Everybody in the neighborhood thought it was hilarious.
Ever since then I have had an interest in repurposing technology and code for fun things.1 -
Murphy's law:

Fucking shit for brains authors that think the digital world is a fantasy realm where everything can happen just to aid their story. Out of boredom i watched "scorpion" today, a tv series about a group of geniusses which are a special case task force.
They got a visitor from the government saying the servers from the federal reserve bank were encrypted with ransomware. I already twitched when they said the economic system would collapse if the servers were left inoperational for a few days. Then one guy got to his desk and "hacked" the fed network to check... he then tried to remove the malware but "it changed itself when observed". But they got the magical fingerprint of the device that uploaded it. In the end some non-programmers created the malware, but it is super fast and dangerous because it runs on a quantum computer which makes it hyper fast and dangerous. They got to the quantum computer which was a glowing cube inside another cube with lasers going into it and they had to use mirrors to divert the lasers to slow down that quantum thingy. And be careful with that, otherwise it explodes. In the end the anti-malware battled the malware and won, all in a matter of minutes.
This is a multimillion hollywood production. How can a movie this abusive to computer science even air on television? Shit like this is the reason people still think the cyberworld is some instable thing that can explode any second. It's not, it's an instable thing that can break down any second. I remember "ghost in the wires" and people had surreal imaginations about the internet already. Shit like this is why people stay dumb and think everything can be done in seconds. If i ever should encounter one of these idiots i tell him i have an app that can publish his browser history by taking a picture of his phone and watch his reaction.
Time to shuw down the tv and learn vim again.11 -
Most successful project at work: NodeJS utility for storing loads of measurements from an application running on various other systems and providing fast ways of getting at that data. No DB, just CSV files broken into time periods. Also has a search function written in C that can very quickly find all user sessions matching the criteria. It's not perfect, but it does the job pretty well and I can tweak the storage engine as much as needed for our use case since its all custom written.
Outside of work: Incomplete right now but I soldered some wires onto an old sound card and managed to get an Arduino to configure it and play some notes on its FM synthesis chip. Still quite a newbie to electronics so this was quite an achievement for me personally. -
Me and my friend > trying to attach a touchscreen display module to raspberry pi.
The module has two rows of female pins like

So there are consequences to being an experimenter. Currently trying to develop my own smarthome, and last night, I was fixing up some lights. Just soldered some wires together, and hung it up by the outlet on the wall. And it worked!
But I didn't want it to just hang, so I moved it around a bit. And obviously because of my shitty soldering job, not really insulating anything, I created a short circuit, sparks everywhere, and blew a fuse in the electrical box. No problem, I'll just replace the fuse.. Except I didn't have any lying around, and it was 1am...
So I had to get up at 8am when the stores opened, and buy some fuses. Couldn't fall asleep again, so I started cleaning my apartment (I've possibly gone crazy from the electrical shock), and now I'm in my 3:30pm till midnight shift...3 -

So this will be my first rant/story sorry if it gets too long.
So finished work and I was like finally some days off, went to bed, woke up the next morning, went to near city to take care of some work, went back and I noticed they were digging the ground near my place, as I've found out from neighbors they were changing some pipes, well ok no problem arrived home, sat on my PC to study a bit and do a bit gaming, but guess what?? NO INTERNET well ok contacted the ISP, the idiots told me it will take them 2 days to arrive WTF? is this 2018 or 1918?? I was so pissed off but ok the next day they called me that they arrived, they checked and said that they will need to fix some wires they will return the same day.. so I've waited few hours but no internet, the asholes didn't came, so the next day they arrived and guess what?! the idiots that digged the holes cut the wires, instead of fucking contacting the ISP to ask for supervisor to tell them where they can dig they didn't know what was the fire for and they thought oh well lets cut the fucking wire, and instead of stopping and contacting the ISP about their mistake they continued with the digging and cut the wire at 3 places, so the ISP at the end called the police, the plumbers that did the digging where just laughing, why do you laugh you primitive ashole, even 10 year old would first ask if it can continue if it finds something that he didn't know about it (I call primitive the person not the job title), and the best part is that the idiots not only they cut the wire at 3 places they also took part of it out of the ground and then they filled the holes back! Now I won't have internet for 2 fucking weeks, yes in 2018 this is happening, at that moment I was so pissed, but kept my cool and contacted the ISP to give me LTE USB stick to use it for the next 2 weeks, sadly they couldn't do that wtf??? So I asked politely who will pay the damage for me not working for 2 weeks and they said that they will gladly pay the damage.. So I was confused because that literally meant that they will compassed me for the 2 weeks, so I re-asked are they sure about that and they said yes, so lets see what it will be done, in the meantime I solved the internet problem by using my phone to access internet on the PC.. But still its amazing how primitive people can be and how ISP don't have alternative solutions for such cases, just to point out this sam ISP bragged how they will be among the first to bring 5G when it arrives... LOL4 -
Fucking exam on Electronic Building Blocks... (aka Arduino). Program this thing ON GODFORGOTTEN PAPER! And then these retards put in that assignment line: max 5 lines of code, for a function that does nothing more than divide two shit eating numbers! And half of my apparently vegetative class fails this! When you were allowed to use your book and notes!
Oh and also, here's a seemingly pissed over image of an arduino with some peripherals, draw the wires. Draw! How the fuck do I keep 21 cocksuffocating wires on a page without overlaps or unclarity? -
Context: We have a 96-port wall-mount patch panel. We're not even using half of those ports. "We" (read: "I") are completely redoing our network rack, as it's an ancient nest of wires. Currently all the ports in use on the patch panel just have random-length cables which are just drooped down beside the rack before running to switches. When I need to trace a cable from patch panel to switch, it's a complete nightmare. However, the cables going to the patch panel do have enough of extra length to do a rack-mount patch panel. I suggest this...
MGR: "Ehhh... I don't really like the idea of tying the rack to the wall... What if we want to move it or something?"
(this rack is in a tiny room and has been there since probably the 1800's.)
ME: "Well the problem currently is that it's all but impossible to trace cables. And even if I rewire it and bundle them nicely, it will still be a headache. With a rack-mount panel, we could just have super short patch cables and so it's super easy when I need to move stuff around."
MGR: "Okkkk..... So what if we would purchase like 3 or 4 switches to get 96 ports, then we run a cable to every patch panel port. That way we never need to change anything :)))."
Dude. Great idea. Let's drop hundreds to thousands of dollars on switches we don't need, rather than just doing a single patch panel. Brilliant. Also another great idea that, running thirty or forty unnecessary cables that we aren't even using. That won't clutter up the rack or use up valuable space or get confusing which ports on the switches are/aren't in use.
I'm trying so hard not to scream right now. I can't deal with this.
EDIT: It gets worse. Apparently part of the reason he wants to do this is "to make it simple". Currently we have our POS system running to its own switch, the printers are on another switch, etc. (yes I know some of this could be accomplished with a VLAN, this was set up before my time). But apparently "if we just had every single port wired then we could plug in whatever we want wherever we want and it wouldn't matter." I just... That's... That's not how you do a network.1 -
In a heavily crowded metro sitting on a ladies senior citizens seat with my 16" laptop almost getting out of hand or pushed by nearby ppl until some oldie got tired of my shit and asked me to stand up.
Imagine the most messed up system of connections on a laptop because i am a droid guy whose laptop had 3 wires coming out of ports (laptop charging cable, usb and earphones)1 -
The feature was to parse a set of fairly complex xml files following a legacy schema. Problem was, the way this was done previously did not conform to the schema so it was a guideline at best, which over the course of many years snowballed into an anarchy where clients would send in whatever and it was continuously updated per case as needed. They wanted to start enforcing their new schema while phasing out the old method.
The good news is that parsing and serialization is very testable, so I rounded up what I could find of example files and got to work. Around the same time I asked our client if they had any more examples of typical cases we need to deal with, and sure enough a couple of days later I receive a zip with hundreds of files. They also point out that I should just disregard the entire old set since they decided to outright cut support for it after all if it makes things simpler. Nice.
I finish the feature in a decent amount of time. All my local tests pass, and the CD tests pass when I push my branches. Once we push to our QA env though and the integration tests run, we get a pass rate of less than 10%.
I spend a couple of days trying to figure out what's going on, and eventually narrow it down to some wires being crossed with the new vs. old xml formats. I'm at a loss. I keep trying to chip away at it until I'm left with a minimal example, and I have one of those lean-back moments where you're just "I don't get it". My tests pass locally, but in the QA environment they fail on the same files.
We're now 3 people around my workstation including the system architect, and I'm demonstrating to the others how baffling and black magic this is. I postulate that maybe something is cached in my local environment and it's not actually testing the new files. I even deleted the old ones.
"Are you sure you deleted the right files?"
"Duh of course -- but let me check..."1 -

Yay today my power extender broke!
(the thing that allows you to connect multiple devices to one sockiet, i dont remember the correct term)
That means i need to buy the new one! Because the old one is using rivots it means i cant repair it!
Stupic fucking lead free solder! Why do you even use this shit for connections? It will create those tin wiskers (small wires) that will short shit! This is the reason why my 3 old power extenders failed! And it is propably the reason why it failed as well!1 -
React's `useEffect()` won't fire if you have someone in your team wrote a hook that maintain a state of an array, mutates the array, empties it, and then set it back to the state.
https://codesandbox.io/s/...
Reported it, ticket closed without asking, told should avoid mutating the object stored in useState.
Isn't it bluntly obvious that if someone spent hours to spot the line in hundreds of lines of code, which actually caused the problem and reduce the whole piece of turds into some understandable minimal reproducible example means they must of course for sure know that by avoiding mutating the array it will fix the bloody issue?
Isn't that bluntly obvious they are trying to say that there is a bigger issue behind those twisted wires?9 -
Here, a full retrospective of my Apple products ownership.
iPhone SE – after Android, I was absolutely amazed by how fast it worked. No UI lags, camera works absolutely instantly no matter the light conditions, all the GPU-heavy games work butter smooth.
After camera and charging port failures on Xperia flagship and CPU literally melting through screen rendering it unusable on Meizu, it was enough to make me interested in Apple products.
When I was using Meizu, I actually got a twitching eye which was triggered by UI lags. After two months of using iPhone, I noticed that something was missing – my eye wasn't twitching anymore.
iPhone actually cured me.
MacBook 12 – a 900 grams laptop with passive-cooled mobile CPU running many Chrome tabs, heavy Webpack HMR build, VSCode and Slack just fine. Yes, you can't play games, but I don't even require it from a laptop this tiny.
Butterfly keyboard that internet hates so much actually increased my typing speed and comfort compared to MX Red mechanical keyboard, and ForceTouch trackpad made me forget about mouse. I learned how to disassemble the Butterfly keyboard if I ever need this but the keyboard never failed.
I use this laptop to this day and it still even smells like the day one, a beautiful smell of a new Apple product.
iPhone X – got it because of the camera, stayed for great battery life and amazing OLED display. I use telephoto lens exclusively and it made me lay off my Canon DSLR with Helios lens which stays on my bookshelf covered in dust to this day.
True black of OLED display which is undistinguishable from the screen bezel is stunning. To this day, battery surely works for one and a half days and I watch youtube really often.
I sometimes struggled to unlock iPhone SE with wet fingers, but with FaceID, as soon as I look at the screen the phone is unlocked. Works perfect every time, never had an issue with this.
Stainless steel body feels premium compared to aluminum. Stereo sound is a major selling point if you're like watching videos and playing games on your phone. Overall amazing product and a huge improvement over SE.
Apple Watch series 4 – really comfortable fit. Nice battery life, once I forgot about it for like ten days during lockdown and it was still working, even though on power reserve mode. Really reliable in terms of battery life and liquid protection. Very satisfying Taptic Engine crown clicks. I run every day and Apple watch always measure my heart rate correctly, and the running app is well designed and a pleasure to use. Overall a nice accessory to have if you use iPhone.
Powerbeats Pro – great sound and battery life. I switched from Shure SE215 which was great, but it had wires. I listen to a lot of music so the sound quality is important for me. When I was choosing earphones I visited a store where you can listen to them all. I listened through earphones like Noble Audio Kaiser Encore and JH Audio Layla, and of course $4000 Laylas sound better than $249 bluetooth earphones, but the difference in sound doesn't justify the difference in price to me.
Powerbeats pro is the Apple H1 chip true wireless earphones with largest driver of them all which makes them sound better than AirPods Pro – it's just physics. Bass in Powerbeats is amazing, which is also true for my Shures, but Powerbeats also win in clarity.
It connects seamlessly to both my MacBook and my iPhone, and everyone in voice chats can hear me really good.
Huge case is a major throwback compared to AirPods, but the battery life of earphones themselves is so great that I just leave the case at home and only carry earphones and it works for me.
Apple Link bracelet in space black – really better than I expected. Intricate detailing, literally the steel that Rolex uses, top-notch finishing and polishing – all that for just 450 dollars. I only used it for several days now, but it already feels like a really satisfying product.
Before all that I was using Linux. It took a year for elementaryos devs to fix wifi for my laptop. Ubuntu looks and feels ugly. Pop OS felt like garbage. Manjaro was also just that – garbage. KDE Plasma – I don't even want to talk about that. A monstrocity where you accidentally click a wrong switch in the settings and your system won't boot up again. Also, PulseAudio. Struggles with proprietary drivers and software updates.
Windows? I serviced a lot of Windows PCs through my career and it never, never worked as intended. I'm no dumbass, I always managed the rights correctly and never installed sketchy apps. My latest ryzen gaming build with a lot of ram also lags somehow even in Windows 10 UI.
Before I switched, I defended Linux.
My life was a lie.
I'm sorry to everyone who I offended based on their opinion on Linux.33 -
Throughout the years I slowly bought more Arduino boards and stuff. But then RadioShack closed shops in my country. So my inventory has remained relatively small.
But now I have been given a ton of stuff. Boards, sensors, wires. More than what I know what to do with.
Someone, please give me a cool project to make.8 -
So last year I sent my PC to get a motherboard replacement, as I couldn't be arsed replacing it or even research what motherboard I should get(was dealing with more urgent personal matters).
Anyway, I get it back and everything works good but not the front USB port.. I always found it weird, but also didn't bother to open the case and double check, so I let it go and assumed, since the motherboard was fried, that the USB wires were faulty.
Time passes by and I decide to open the case for annual cleaning job... Turns out the motherfucker didn't connect the port, why?? Fucks knows why... Obviously the wires were "short" and he didn't even try to pull it out further!!! You little piece of shit,for a full year I've been living with a missing usb port, the fucking front facing mother fucking usb port. Fuck.
Moral of story? Don't be a lazy ass and fix your shit on your own!4 -
I told you guys that I would update you on my PiBM-5150 project. I figured out the hard way that my USB to DB-25 cable wouldn't cut it. Seems it is for printers and no matter how hard I tried it wouldn't work because of the path of the wires. After researching, it is apparent that the GPIO pins on the pi are configured for serial by default but it requires a little voltage change from TTY to RS-232. Rather than do like one of the videos I saw and solder junk to a bread board, I found a serial (rs-232) shield and 9pin output for the pi. Now, both computers are true rs-232 each. Instead of using a modem between them, I bought a null modem cable (crossover of Tx Rx signals) to interface the two machines directly. I'll update this evening to show it hopefully working.

I didn’t know Python so they made me go into the (cold) server room and fiddle and plug in wires to boxes. Don’t think I actually learned much.3

!dev. Been working on a simple and 'cheap-ish' enclosure for my resin printer to evacuate fumes out a window. 100% not the best or cleanest looking method but I like it. I don't usually do things with my own two hands so this was kinda fun. Probably will do a V2 in the future with my brother teaching me to do more hands on skills. And a MUCH cleaner end result. This was him telling me what i needed to do and me figuring out the how on my own lol
Now to finish v1 I just gotta put the fan controller outside where I can physically touch it. Cut holes for its wires. Then foam anywhere that stick on door foam didn't work that air can escape. Ohhh and attach the actual duct and window parts

Client emails and asks why a certain element appears on particular page of their website. I respond by saying that they'd asked me to place it there. I then find and forward them the email in which they requested that I place the element on the page. Client replies to forwarded email, "What is this in relation to?".
I must stress that this was all in the space of about two minutes and no other emails were exchanged in-between; there was zero possibility of crossed wires. -
Can anyone help me with this theory about microprocessor, cpu and computers in general?
( I used to love programming when during school days when it was just basic searching/sorting and oop. Even in college , when it advanced to language details , compilers and data structures, i was fine. But subjects like coa and microprocessors, which kind of explains the working of hardware behind the brain that is a computer is so difficult to understand for me 😭😭😭)
How a computer works? All i knew was that when a bulb gets connected to a battery via wires, some metal inside it starts glowing and we see light. No magics involved till now.
Then came the von Neumann architecture which says a computer consists of 4 things : i/o devices, system bus ,memory and cpu. I/0 and memory interact with system bus, which is controlled by cpu . Thus cpu controls everything and that's how computer works.
Wait, what?
Let's take an easy example of calc. i pressed 1+2= on keyboard, it showed me '1+2=' and then '3'. How the hell that hapenned ?
Then some video told me this : every key in your keyboard is connected to a multiplexer which gives a special "code" to the processer regarding the key press.
The "control unit" of cpu commands the ram to store every character until '=' is pressed (which is a kind of interrupt telling the cpu to start processing) . RAM is simply a bunch of storage circuits (which can store some 1s) along with another bunch of circuits which can retrieve these data.
Up till now, the control unit knows that memory has (for eg):
Value 1 stored as 0001 at some address 34A
Value + stored as 11001101 at some address 34B
Value 2 stored as 0010 at some Address 23B
On recieving code for '=' press, the "control unit" commands the "alu" unit of cpu to fectch data from memory , understand it and calculate the result(i e the "fetch, decode and execute" cycle)
Alu fetches the "codes" from the memory, which translates to ADD 34A,23B i.e add the data stored at addresses 34a , 23b. The alu retrieves values present at given addresses, passes them through its adder circuit and puts the result at some new address 21H.
The control unit then fetches this result from new address and via, system busses, sends this new value to display's memory loaded at some memory port 4044.
The display picks it up and instantly shows it.
My problems:
1. Is this all correct? Does this only happens?
2. Please expand this more.
How is this system bus, alu, cpu , working?
What are the registers, accumulators , flip flops in the memory?
What are the machine cycles?
What are instructions cycles , opcodes, instruction codes ?
Where does assembly language comes in?
How does cpu manipulates memory?
This data bus , control bus, what are they?
I have come across so many weird words i dont understand dma, interrupts , memory mapped i/o devices, etc. Somebody please explain.
Ps : am learning about the fucking 8085 microprocessor in class and i can't even relate to basic computer architecture. I had flunked the coa paper which i now realise why, coz its so confusing. :'''(14 -
Competition judges don't believe that a Google Assistant based system running on a Raspberry with recipes, ingredients, YouTube and Spotify streaming, Kodi streaming, lights control and other stuff, qualifies as an IoT project.
For them, it just equates to the number of sensors and ugly wires sticking out a Raspberry, with some 1-file Python program.
Thoughts on this?5 -
My power supply project is almost completely done (it's in a working state but still needs some finishing touches) but I procrastinated with it for nearly 2 weeks. The reason being that the next step (making a side panel and soldering some 3600W AC lines to the ones inside of the unit) fucking sucks. I've done that soldering of 4 wires (3 inside lines, 1 coming in from the outside) before, and I honestly can't think of many things that I've cursed and sworn on as frantically as I did on this. This time of course being no different, plus some unstoppable coughing and stuffed nose, just because my body felt like acting up. Can't say that I had a good time.
But that's not really the point of this.. it's more about the procrastination part. It isn't really procrastination as in just being too lazy to get around doing something, is it? It's more like the reluctance to do something that you know is going to suck really bad. And even now I've only quarter-assed it (well probably half-assed, quarter-assed would've been the crocodile wires between the inner and outer AC lines.. just dangling on the floor, waiting for someone to step on.. beautifully dangerous, deadly almost.. just the way I like it :3)... Anyway, how do you get the "umpf" to do something that you really dislike and don't want to do, without waiting for 2 weeks to finally get around doing it?4 -
What is with me and my headphones ? 4 headphones , all broken after 4 to 5 months of use and one recent headphone rendered unusable after 1 month . I am going to ditch wired headphones for good ! That fragility of the wires near the connector .. I suspect they are intentionally made fragile to frustate the customer and make them buy a new one !! :(6

A game where you build creatures from muscles, tendons, bones, blood vessels, other fluid containment and transport organs, as well as nerves and brains. Probably would look very gross. Gore-centric game.
Similarly, a game where you build robots out of Pistons, gears, Axels, fluid tanks and hoses, engines, sensors, computers and wires.
Either one of these premises is pretty amenable to a backstory where you're trying to escape-from/survive-on an alien world. -
Come in to work, sit down at desk, coworker comes in. Tells me I'm going to potentially start crimping grounding wires for 40 racks. Shows me the email, I notice I'm not in the CC chain. I love not being in the know about work I may be doing that isn't in my job description.1

Client needs a section of their current website redesigned and add some functionality based on user interaction with the website.
ac - account director
ac: Need timings on FE build for his section on the website.
me: Cool can I see the wireframes/designs?
ac: No wires yet, designs are here...
me: *sees 3 pages mocked up out of 50 different ones in this particular section, and they all have different functionalities*
me: I can only give you estimates on the designed bits
ac: Just estimate based on the UX proposal, it's here...
me: *reads first line - "Make F&Q section and sub pages more visual*
me: Tasks described in the proposal are too generic!
ac: Just estimate based on the previous work done for this client (which have nothing to do with the current scope)
me: *dies and goes to freelancer heaven*1 -
because I lacked a portable storing solution (pockets weren't allowed), I couldn't find anything better than using my own skull as a storage box. It turned out it had way more room than expected. The brain itself is quite small, and the whole frontal lobe & the space around the brain is completely empty. Initially, opening the skull was scary and cumbersome, but the more you do it, the easier it gets. Once upon a time, when I tried to pop an acne on my forehead, the hole was revealed, and it led to the storage space beneath. I have no idea how it happened, but apparently the skin is too thin. The bone also looks much thicker from the inside. There were two wires — red and black — leading to a standard PC speaker every old computer had. I wasn't a cyborg, mind you, I merely put that speaker there for storage. The acne hole healed with those wires exposed, leaving a permanent mark due to the wire coloring pigment dissolving in my skin.
I used that storage space to hide the contents of some parcels I was processing back then. I was stealing things. Eventually, my coworker — Bruce Willis — confronted me, and I had to strangle him. My arm became very flexible, and I was able to wrap it around his neck several times during a chokehold. It didn't end well for both of us. -
Is it safe to assume that Dell's power button PCB-s all communicate the same way? They all have a single button and four wires.2

Did they fire Jony Ive and we all missed it?
Seriously, I'll have to stick to my iPhone 6 one more year, with every single android fanboy making my life miserable for having an outdated phone!
And those stupid airpods...
What the hell, cutting off the bloody wires doesn't make them exactly the next big thing, more like the dumbest!7 -
going to redecorate my room with a plasma/glowing/physics theme to the best i can afford. i've a lubbeen plasma ball, some lasers, a smart mirror. gonna try to get (or make) tesla coils. gonna glue my rpi to the wall and put the wires alongside it. what else would you guys add?
i want to add a projector maybe. is there anything else you guys would add? maybe a cool lamp? also, any ways to add in another rpi/arduino other than the smart mirror that you guys can think of?1 -
This is my iphone charger. I have to charge my phone 32 hours per day because the battery is dogshit.
U can see how fucked it is from charging so much. The cable itself ripped apart and u can see the wires inside but no wires are sticking out.
I get ZAPPED when i touch anything in my environment. Anything i touch electrocutes me. Like im the fucking Zeus.
Could this cable be the reason?

Before he began dropping the 20K proposed to remodel my flat, I told my father I much preferred a contractor who was recommended by someone I knew, as opposed to using a big corporation like Home Depot. FAMOUS LAST... a neighbour in my building highly recommended the contractor we chose. And, week 7 [or is it 8?] of what was proposed to take no longer than two weeks has begun afresh!
On Friday the fellow who is the owner of the contract remodeling company was here touching the paint. He was here because I forbade the two painters he sent to do the initial painting job.
My internet cut out suddenly around 1300 Friday. He set to leave for the weekend shortly after that. I mentioned the outage to him. The essence of his reply was that there was no way it could have had anything to do with him. The following day, my internet provider sent a tech out to diagnose the problem. What was the problem? The head of the remodeling firm removed a face plate from the wall where there were telephone wires and disconnect them when he tore the wires as he replaced the face plate.
Although the tech told me he wasn't going to charge my account the $85.00 fee for his services because the outage was caused within my flat, I wish to be sure of this. Which brings us to the punchline.
My internet provider is a lame ass business model, dreamed up by a squint-eyed ex-circus monkey, never well endowed in the top story, and now just plain sad.
There were some 911 outages in Washington State last Thursday night. All during the day Friday when you dialled their freephone #. the recorded announcement, before saying anything else, told you they were experiencing heavier than usual call volumes, and my wait would be greater than `10 minutes. Fine. What fried my La Croix silk was that after their customer service dept closed for the weekend, that outgoing message remained.
Today, I wanted to contact my provider to see if they would know if the $ was going to be charged to my account. After pressing the 'send' key, my computer came back with an error message, saying they were having technical difficulties. So, I went on over to the 'chat' page. There's nothing to click on to take me to this enfabled location. So, can't reach them by phone unless I want to hear, every 30 seconds whether or not I wish to, how sorry they are for my delay.
A few years ago I would've used this as an excuse to have a technicolour meltdown. The reason I'm posting this is that I am now able to see beforehand what I'll be doing to myself getting upset over the circumstances. When I do reach somebody, I'm going to tell them as lightly as possible, that if they were an airline, I wouldn't board any of their aircraft. Ever. -
Over the weekend, I made the move to use a flash as a repository (don't need no wires to repo!). Felt that needing 12 MB to store less than 2 MB was a little bit high.
So I figured "simple fix, I'll just reformat the drive from 32Kb allocation to something less, like 4Kb".
After 30 seconds of a single copy/ paste, the transfer was complete. Checking the size... accidently clicked "4096 kilobytes" instead of "4096 bytes".

Can anybody share some tips on desktop devices that will make my life easier? I build apps and websites on multiple devices. My desk is a mess, devices are all over the office, wires are everywhere.I need more zen.
I need some kind of shelf or tray that holds maybe 5+ different tablets/mobiles neatly. I also need charge points, maybe a nice under-monitor tray. Needs to be robust.
Thanks6
