Woohoo! 32k achieved!!! Finally I can post some new rant without risking some sudden overshoot 😁
So putting celebrations aside for a minute, a while ago I've noticed a tingle when I stroke my finger across metal areas of my tablet, or the sides of my phone (which probably has metal near it too) while it's charging. And it's been bugging me ever since.
Now, some things to note are that it only happens when my feet are touching the ground though slippers, and that the frequency is so low that I can actually feel the tingle when I slide my finger across the material. This to me at least seems like electricity flows through me into ground, and touching the ground directly provides a path so easy for the electrons to run away that I don't feel it at all. But if I lift my feet off the ground entirely, I just get charged up and after that, nothing else happens.
So those are my ideas. The answers on the subject on the other hand.. absolute cancer. Unsurprisingly, most of them came from Apple users. Here's some of them.
https://discussions.apple.com/threa...
- I've not noticed it, but if you're concerned bring the phone to Apple for evaluation.
- Me too facing same problem.. did u visit apple care?
And one good answer at least...
- google emf sensitivity, its real. You are right, there is a small current flowing through your body, try to limit your usage. The problem with this issue is those who aren't affected (lucky ones for now) will tell you these products are 100% safe. To a degree they are, i used my ipod touch for about 2 years straight vwith virtually no symptoms. then the tingling started and it gets worse.You will get more sensitive to progressively less powerful things. I dont want to scare you but just limit your usage like i didnt do 🙂
Overall that discussion was pretty good actually, aside from "bring it to the Genius Bar, they'll know for sure and not just sell you another unit". But then there's Reddit.

- Ok, real reason is probably that the extension cord and/or outlet is probably not grounded correctly. Either that or you are using a cheap knockoff charger.
Either use a surge protector and/or use the authentic Apple Charger.
- It's not the volts that hurt you, it's the amps
- I think you are in deep love with your phone. That tingling sensation is usually referred to as "love" in human language.
- Do less acid, I would advise.
Okay, so that's the real cancer. Grounding issue sounds reasonable despite it being wrong. Grounding is actually not needed when your charging appliance doesn't have any exposed metal parts. And isolation from high voltage to low voltage side actually happens through things like routering holes into the PCB, creating spark gaps, and using galvanic isolation through things like optocouplers. As for a surge protector? I'm using them to protect my PC and my servers, but the only purpose they serve is to protect from.. you guessed it.. voltage surges, like lightning bolts hitting the grid. They don't do shit for grounding or reducing this tingle! What a fucking tool.
It's not the volts that kill, it's the amps.. yeah I'm sure that the debunking of that is easy to find. Not gonna explain that here. And the rest of it.. yeah it's just fucking cancer.
Now what's the real issue with this tingle? It's actually a Class-Y rated (i.e. kV rated) capacitor that's on the transformer of any switch-mode power supply, including phone chargers. If memory serves me right, it helps with decoupling the switching noise and so on. But as it's connected to the primary side of the transformer, if the cap is sufficiently large and you are sufficiently sensitive, it can actually cause that tingle by passing a fraction of the mains electricity into your body. It's totally safe though, as the power that these caps pass is very small. But to some, it's noticeable.
Hope you found this interesting! And thanks a lot for bringing me to 2^15. I really appreciate it ♥️

N: Me
C: Keurig Coffee Machine
N: *Turns on surge protector and keurig*
C: WAIT, PREHEATING
N: *Lifts handle to put Keurig cup in*
C: LOWER HANDLE TO PREHEAT
N: Fine, I'll just wait.
C: FILL WATER TANK
N: Wtf I just sat here for like 3 minutes and now you tell me? *Fills Tank*
C: WAIT, PREHEATING....
N: *Waits another 3 minutes*
C: INSERT CUP
N: *Inserts Cup*
C: *Makes coffee in 1 minute*
C: ENJOY COFFEE. WAIT, PREHEATING
N: *Turns off surge protector before finished preheating*
Is this really nitpicky shit? I feel like I have to babysit it through the entire process.11 -
So I'm working our remote build/testing server, and all of a sudden my computer just turns off. No crash message, no error, just turned off. My co-worker tries to help troubleshoot the problem.
Nothing.
I take the computer downstairs to the hardware department. They plug it in and it starts no problems.
After it finishes updating, I take it back upstairs and plug it back in.
Nothing.
I suggest that it is the power cable, and my co-worker looks under his desk. Turns out he had kicked the switch on the surge protector. 😑1 -
I've been having blackouts a lot recently which kills my desktop so thinking I should buy a UPS specifically APC UPS Battery Backup & Surge Protector with USB Charger, 600VA, APC Back-UPS (BE600M1) https://amazon.com/dp/B01FWAZEIU/...
But not sure how I would maintain it/use it.
Basically it would replace the current per strip I'm using for PC and monitor?
I don't know though how long it would last for my gaming PC though. What is the 625? I need it to last at least 5 minutes so it can shutdown properly but it's a gaming desktop... So will it be enough. I don't know what the VA means... Also I have a 4K 27in monitor...
That and I'm a bit worried this thing blows up and starts a fire...16 -
So I've been using Duet on my iPad Pro for a couple years now (lets me use it as an external monitor via Lightning cable) and without issue. Shit, I've been quite happy with it. Then the other day, whilst hooked up to my work laptop, there was a power fluctuation that caused my laptop to stop sending power to connected devices. Which is fine - I have it plugged into a surge protector so these fluctuations shouldn't matter. After a few seconds the laptop resumed normal operation and my connected devices were up and running again.
But the iPad Pro, for some reason, went into an infinite boot loop sequence. It reboots, gets to the white Apple logo, then reboots again.
In the end, after putting the iPad into recovery mode and running Apple's update in iTunes (as they recommend), it proceeds to wipe all my data. Without warning. I lost more than a couple of years of notes, illustrations and photos. All in one fucking swoop.
To be clear, you get 2 options in iTunes when performing a device update:
1. UPDATE - will not mess with your data, will just update the OS (in this case iPadOS)
2. RESTORE - will delete everything, basically a factory reset
I clicked UPDATE. After the first attempt, it still kept bootlooping. So I did it again, I made sure I clicked UPDATE because I had not yet backed up my data. It then proceeds to do a RESTORE even though I clicked UPDATE.
Why, Apple? WHY.
After a solemn weekend lamenting my lost data, I've come a conclusion: fuck you Apple for designing very shitty software. I mean, why can't I access my device data over a cabled connection in the event I can't boot into the OS? If you need some form of authentication to keep out thieves, surely the mutltiple times you ask me to log in with my Apple ID on iTunes upon connecting the damn thing is more than sufficient?! You keep spouting that you have a secure boot chain and shit, surely it can verify a legitimate user using authenticated hardware without having to boot into the device OS?
And on the subject of backing up my data, you really only have 2 manual options here. Either (a) open iTunes, select your device, select the installed app, then selectively download the files onto my system; or (b) do a full device backup. Neither of those procedures is time-efficient nor straightforward. And if you want to do option b wirelessly, it can only be on iCloud. Which is bullshit. And you can't even access the files in the device backup - you can only get to them by restoring to your device. Even MORE bullshit.
Conversely, on my Android phone I can automate backups of individual apps, directories or files to my cloud provider of choice, or even to an external microSD card. I can schedule when the backups happen. I can access my files ANYTIME.
I got the iPad Pro because I wanted the best drawing experience, and Apple Pencil at the time was really the best you could get. But I see now it's not worth compromise of having shitty software. I mean, It's already 2021 but these dated piles of excrement that are iOS and iPadOS still act like it's 2011; they need to be seriously reviewed and re-engineered, because eventually they're going to end up as nothing but all UI fluff to hide these extremely glaring problems.2
