A couple of years ago, I was working in a computer shop as a "technician", I was 15, first job I ever had.
One day an elderly lady came into the shop, probably 50'ish, she and her whole family "suffered" from electromagnetic radiation, and the mother had the worst suffering. She complained about her TV box that just had died.

I accept the tuner and see it's wrapped with 10 layers of aluminium foil, with a tiny hole for the IR receiver.

The whole box smells like burnt electronics, and the foil gets darker for each layer I unwrap. I try explain to her that the box gets warm and overheated by wrapping it like this, and she's lucky that it didn't catch fire.

I further explain to her that she will not get a new box, because the warranty does not cover _this_. The mother tells me she has to wrap it like this, because she gets headaches when she's watching the news.

She then proceeds to go into a rage mode and gets her whole family into the shop, where all of them starts yelling at me, the younger kids start throwing stuff down from the shelves and touching the TVs with sticky fingers (literally, sticky, like yuck!).

Unsure what to do, boss is in a meeting, and my colleague is busy in the back.

So I calmly tell them that in this building there's 4 wireless networks, 3 wireless phones, high voltage cables run in the wall behind me, there's factory tracks 20 meters behind the building, next door business is an electrician, you're standing in front of wall with 30-40 TVs, 5 HDMI splitters, 3 TV boxes and a Blu-ray player. And they've all been standing in front of them for the last 10 minutes.

They all suddenly feel really sick and run out of the store, never to be seen again. From that day, I decided I'll never work in a shop again, and pursued my dreams to become a developer.

TL;DR: Family is "sensitive" to electromagnetic radiation, almost put burnt down their house because of stupidity, yelled at me. I decided to pursue my dream as a developer.

A new toy arrived today. Time to go back to soviet russia and have some fun!!

*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.

*listens to some music over the Bluetooth headset in Groove on Windows*
*walks off to the bathroom*
> Please recharge headset
…
Which in Sony-speak means "reached cut-off voltage, you'd better recharge this fucking thing because we will power off now, rendering the warning completely useless!*
Me: "oh dear it's 5:30AM and my speakers are set to full blast"

*rushes off to the bedroom to pause Groove*
*walks back to the bathroom*

Then I started thinking, you know Microsoft.. on my phones I never had this issue since the Samsung Corby. Android has supported pausing media playback on headset disconnect for about a decade now. Maybe Microsoft Certified Enganeers could look at how the competition has solved an issue and IMPLEMENT THE FUCKING FEATURE ALREADY?!

But no, you've got that IE reputation to hold high. Sorry, I forgot.

MICROSHIT!!!!!!

I so fucking hate mosquitoes. At this point I'm seriously willing to lure all those bitches in and guide them straight to an electrical death. Problem is, I know how to generate super high voltage to char the fuckers right into smelly dust, but I don't know how to lure them in, or even find them manually, so let alone automatically. Even a chemical reaction we can electronically dispense to lure in the fuckers, but I have no idea what that chemical stuff would be. I'm not a chemist (yet). But if I can build it, fucking hell.. I would build a ton of them, weaponize my entire home and even build some spares to send off to fellow ranters. Because those parasitic bitches must DIE!! The only reason why they still exist after thousands of years is because we didn't kill the fuckers yet. I want to fucking kill the leeches, preferably in the most gruesome way possible.

So yeah. A shout for help to my fellow ranters this is.. perhaps even a collab. I have no idea about the stuff that draws those fuckers into their death. Any suggestions? Whoever can guide me to the demise of those parasitic pieces of shit, seriously.. if at all feasible, I'll build it for you and ship it!! Death to those parasitic blood-sucking bitches!!!

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've just disassembled this LED floodlight that I bought a while ago. It's some stupid little cheapie from a dollar store, so I figured that there'd be shit inside. But I wanted that LED cob.. a power LED :3

Well, shit wasn't too far off from the truth. The component choice is reasonable, but the design of the bloody thing.. batshit insane. The LED floodlight is powered by 4 AAA batteries, connected in series. So 6VDC. That then goes into this little tactile pushbutton, into the LED cob and then a 4.7 ohm resistor.

Well that's a pretty easy circuit.. let's remove the batteries and the casement, and put it on the lab bench power supply. Probes connected to the circuit with only the resistor and the LED cob in between (I didn't want to deal with the switch). Power supply set to 6V, current limiting to 500mA, contact!! And it works, amazing! So I let it run for a while to see that nothing gets too hot.. hah. After a minute or so, smoke would come out.. LED cob was a bit warm to the touch but nothing too bad. But the resistor.. I could cook water on it if I wanted to! 100 fucking °C, and rising. What the F yo?!

So I figured that I didn't want to put the resistor in between there. Just the LED cob now, which apparently has a forward voltage somewhere between 3.2V and 3.3V depending on how I set the current (500mA and 600mA respectively). Needed a bigger heatsink though, so I jammed one of my aluminium heatsinks on there. And it worked great! Very bright too, as it takes between 1.6 and 2W of power. Just for a comparison, the lighting in my living room is 4x5W and the ones on top of my dining table are 2x3W (along with some TL bar that my landlord put there.. fluorescent I think). So yeah, 2W is quite a lot for an LED, especially when it's all concentrated into one tiny spot.

That said, back to the original design with the resistor. 2 questions I have for that moron that designed this crap. First, why use a resistor for a power LED?! They needlessly waste power, and aren't good choices for anything that consumes more than 100mA. You should use PWM for these purposes, or tune your voltage on the supply side. Second, why go with 6V when your forward voltage is 3.3 at most? Wouldn't it make more sense to use 3 batteries with 4.5V? Ah, but I know the answer to the second one. AAA cells aren't rated for high loads like this. So that's likely why the alkaline cells that I had in there before have started leaking. Thanks, certified piece of shit!

Honestly, consumer electronics are such a joke... At least there's some components that I can salvage from this crap. Mainly the LED cob, but also the resistor and the tactile pushbutton perhaps.

One last remark that I'd like to make. This floodlight was cheap garbage. But considering that you can't do it well at that price, you just shouldn't do it. You know why? Because consumers always go for the cheapest. Makes a lot of money to build at rock bottom prices and make shit, but it damages the whole industry, since now the good designs will go out of business. That's why consumer electronics is so full of crap nowadays. Some unethical profiteering gluttons saw money, and they replaced the whole assortment with nothing but garbage. I'm sure that there's a special place in hell for that kind of people.

Can’t believe I forgot to post this one:

“Science does not say you shouldn’t pee on high voltage lines, it says urine is an excellent conductor.” - Sabine Hossenfelder

South Africa Electricity:

This is after I lost my 7th 3000VA online UPS...

In South Africa we have 240V power most of the time which is great, but then there is scheduled power outages (because our electricity companies cannot "handle the load").

When we have a power outage we have automatic generators which brings everything back up although there is still the 1 minute drop which has weird spikes and odd voltages before switching to the generator (as the generators wait until they are stable)

This has being destroying our equipment, we had a $2000 repair bill 3 TIMES for 3 SEPERATE Xerox Machines that have surge protectors although their circuit board somehow fried.

We have lost 7 3000VA UPSes (3 different brands) and 5 voltage regulators we put to protect the UPSes.

The one UPS that fried just had 2 dead fuses, I decided to replace them (unplugged the batteries to avoid 240V) and when plugging the batteries back in there was a huge spark and flame and the metal and plastic melted onto the board and turned black (the metal pins to connect the battery are non existant now)

I am done with electricity...

P.S. 2 of our generators also got hit by lightning as we are high on a hill and ALL the plastic cable coverings inside the generator were melted

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)

26 or so hours up now. And I've got a few stories to tell :) feel free to refresh your cup of coffee and take a seat.

Last few days I've been going into this odd place called intown.irl to get in touch with its inhabitants. An odd place I have to say. But in some cases quite rewarding, even got a MILF home with me and into bed at some point. Anyway...

3 days ago I think it is now? Thursday evening I took my laptop to this local bar where I had this issue about dihydrogen monoxide with one of the bartenders earlier (you'll find that rant on those keywords). Still wanted to visit it regardless though, as I met that first woman there earlier that approached me. Unfortunately I didn't see her there that day.

Some bald guy who was clearly drunk approached me. Many people were already giving curious looks at this laptop I brought to the bar. I finally tuned it up with the stickers from FOSDEM.. I'll put a picture of it in the comments. My theme was one of privacy (central), distributions and Google's open source initiative (which aligns with the keychain token I got from them as well). But of course.. that guy.. he thought that a pimped/riced laptop obviously meant that I was a hacker.

Guy went to the toilet.. went back.. and suddenly grabbed my laptop and turned it towards him. Boy was I never more smugly satisfied that those rubber pads on the bottom are quite resilient. Could've almost damaged my screen by trying to grab it like that. But it's a CCFL display.. so high voltage. If it were to become broken.. worth it. 😈

On it at the time was a terminal, pinging Google (had network issues at that bar, to the point where one of the - I think - staff members got up to me and offered the WiFi password and got to talk with me.. more on that later), and my usual Linux desktop along with the Arch anime wallpaper with the quote of Da Vinci.. simplicity is the ultimate sophistication. Of course the guy saw the terminal.. and probably reaffirmed.. yep, that's a hacker. At least he wasn't too wrong about the general term.. but the hat.. most likely he was wrong on that one.

Guy left with this question.. "you are a hacker, aren't you."
I replied to him: "No sir. I'm not a hacker. I've got no idea what you're talking about."
Guy kept looking at me weirdly for the whole night to come.

Back to that companion guy though. Mac user, yada yada.. but he told me about his backup solution. Apparently - I shit you not - he has not only the photos on his local device, he's also frequently backing them up in Time Machine (which I was really curious about whether it uses mirroring or snapshots.. he couldn't tell, lmk if you do) but not only that.. he was storing another offsite backup in that very bar, in case his house went on fire.

Now that is a proper backup scheme!!! If only more people were like that.

Seriously though.. that bald guy who took my laptop just like that... I just let it slide for that one time, but I tend to treat my machines as an extension of my very self. I think that was a very uncalled for move. Asshole...

How would you have reacted to such a thing? And.. maybe that's why we technologists don't get outside too often? Fucking everything is hacking these days if it's not Knopkes and Blinkenlights… Not every shell is a h4xx0ring console for h3kk1ng de fasbuk…

God, the iPhone 11 pro's triple cameras ARE SO UGLY. OnePlus 7 has three back cameras and it's not ugly, so it can be done! It's just so, so fucking ugly. It looks like where you might plug in a high voltage power cable or something. And of course it still has a notch. That's two design failures in one expensive phone. No thanks!

(From owner of iPad Pro - not an Apple hater!)

I am trying to reverse engineer a fingernail hardening device for rapid hardware prototyping (becoming some kind of hardware developer I guess)

Since it is a fucking mess (all cables are black) they've chosen a weird construct to operate microcontroller on 240Vac (seems to be possible and made in very low energy consuming devices) i do not find any datasheet for one of the used products. It would help a lot but no. And messing around with high voltage is no fun.

I'm unsure if this fits as a dev rant since most/all I've read so far are software-related.

Was in a university group project and had to make an angular momentum measurement device. An hour before demo voltage on one of the pins was still a bit too high. Friend drove to Chinatown not too far away from campus and bought a pack of the cheapest batteries. Plugged the cheap batteries in, the voltage was just spot on. How awesome was that!

I don't know why you expect your website to be done in a month when you can't even fucking decide what it should be.

I CAN'T READ YOUR MIND ASSHOLE.

Don't tell me that I did it wrong or it doesn't look right when you said that you wanted it like that.

I wasn't hired as a web developer, I've done high voltage electrical work, machinist work and repair of the shit you can't even take care of. All for 15usd a hour. If they don't keep their promise to bump the pay....
