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.

Electronics store clerk: "Can I help you?"

Me: "Good afternoon sir. I'm a developer and lifelong PC gamer. I received a second hand PS4, and might buy a next gen console at the end of the year. People tell me that in front of this soft wide desk chair people call a "couch", you need some sort of large computer monitor to enjoy console gaming"

Clerk: "Yeah, we sell TVs. What TV do you have now?"

Me: "I don't own a TV. I just want a huge 4K computer display with a good response time, excellent refresh rate, and great contrast"

Clerk: "OK so this is an entry level 55" smart TV. It's 120hz, QLED, has full array local dimming. It's great for gaming. It's €1000. We also have this LG OLED smart TV for €1200, which is a step up in terms of contrast and response time..."

Me: "Wait... Smart TV? No, I don't want a TV with an operating system. I want a computer display."

Clerk: "There aren't a lot of big computer displays. We have this ASUS ROG 55" computer monitor. It's also 120hz. Very similar response time, but the brightness and contrast aren't as great, it's edge-lit"

Me, trying really hard to make out the contrast differences under ugly fluorescent lights of the store: "So it's a worse big couch display, without smart OS. How much is it?"

Clerk: "€3500"

Me: "So what you're saying is that while the displays are similar or even better, the operating system on all these TVs is so incredibly bad, you have to give €2500 discount for people to even buy it?"

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.

4 Weeks ago i went to a Electronics store here in germany. My Intention was to look at some smaller laptios (12-14 zoll) to use while im traveling to my work. While i was looking at some Laptops i hear a conversation next to me between a customer and a guy working at the Electronic store.
He says to the customer That the Laptop has a 8 zoll Monitor pointing at the Laptops bottom. My First thought was wtf because i dont knwo any Laptop with an 8 Zoll screen but its still possible. After they done talking i walk to the Laptop and look at the Spot the guy was pointing at. There was a battery sign saying 8h battery duration. says no more :)

One job I picked up was for an IoT Start Up. It was quite interesting work, reporting to the technical director, who was an electronics engineer, who was designing the hardware himself, they had a couple of firmware guys already, and just needed someone to take care of the software.
So they said they needed something in Azure that they could stream their data to and provide analytics for their clients. It had to be Azure, and it had to be Azure Native, and was to be Multi-client, as they had a deal with Microsoft to showcase how well Azure works in the IoT space at an exhibition/conference in 3 months time.
So I worked flat out for 3 months, on a whole variety of technology, from C++ to get the radio packets from their IoT chip, Python to run on the hub to take the data from the C++ and stream it to the cloud, Azure IoT Hubs in every continent to receive the data and store it an a Cosmos DB, and then Power BI analytics wrapped up in an Angular front end that the clients could log into.
Got it finished 2 days before the show, and they were so pleased I got flown business class to Singapore to be on the stand and talk to customers.
The first sign of trouble was when we arrived at the show to find we just had one of those little circular tables with two stools in the middle of the floor, about two feet across and no power.
No problem, I was able to sort that, swapping laptops in and out.
Microsoft were really happy with what we had, and couldn't believe I had thrown it all together in 3 months.
We picked up a potential customer for the system, a major Asian Telecoms company.
Then when we got home, the CEO swooped in. I had never met this guy before. Imagine one of the VC guys from Silicon Valley, or the CEO from the IT Crowd. You get the picture. Could talk the hind leg of a donkey, and real street smart, but no brains. He insisted on "taking it from here" and flew alone to strike the deal with the customer. Came back with an MOU in his pocket and said to me, their guys will be in touch with you.
Then I got a call. Can you send us the source code and tell us how what servers we have to run this on?
Um, its cloud native.
No, we can't use a cloud it has to be on our servers - your CEO told us that was no problem..
He hadn't even taken the trouble to find out what it was we had built, and what he was selling.

Today I bought some parts at Conrad Electronics (they have a blue logo) and wore a blue shirt.
I got asked for technical support a total of five times.😅

A while ago at the electronics store...
That touchscreen should give customers the opportunity to review their products, but instead you were able to mess with their network and system 😁
Of course i did not harm them.

Btw. it says Linux in the lower left corner :o

ZNC shenanigans yesterday...

So, yesterday in the midst a massive heat wave I went ahead, booze in hand, to install myself an IRC bouncer called ZNC. All goes well, it gets its own little container, VPN connection, own user, yada yada yada.. a nice configuration system-wise.

But then comes ZNC. Installed it a few times actually, and failed a fair few times too. Apparently Chrome and Firefox block port 6697 for ZNC's web interface outright. Firefox allows you to override it manually, Chrome flat out refuses to do anything with it. Thank you for this amazing level of protection Google. I didn't notice a thing. Thank you so much for treating me like a goddamn user. You know Google, it felt a lot like those plastic nightmares in electronics, ultrasonic welding, gluing shit in (oh that reminds me of the Nexus 6P, but let's not go there).. Google, you are amazing. Best billion dollar company I've ever seen. Anyway.

So I installed ZNC, moved the client to bouncer connection to port 8080 eventually, and it somewhat worked. Though apparently ZNC in its infinite wisdom does both web interface and IRC itself on the same port. How they do it, no idea. But somehow they do.

And now comes the good part.. configuration of this complete and utter piece of shit, ZNC. So I added my Freenode username, password, yada yada yada.. turns out that ZNC in its infinite wisdom puts the password on the stdout. Reminded me a lot about my ISP sending me my password via postal mail. You know, it's one thing that your application knows the plaintext password, but it's something else entirely to openly share that you do. If anything it tells them that something is seriously wrong but fuck! You don't put passwords on the goddamn stdout!

But it doesn't end there. The default configuration it did for Freenode was a server password. Now, you can usually use 3 ways to authenticate, each with their advantages and disadvantages. These are server password, SASL and NickServ. SASL is widely regarded to be the best option and if it's supported by the IRC server, that's what everyone should use. Server password and NickServ are pretty much fallback.

So, plaintext password, default server password instead of SASL, what else.. oh, yeah. ZNC would be a server, right. Something that runs pretty much forever, 24/7. So you'd probably expect there to be a systemd unit for it... Except, nope, there isn't. The ZNC project recommends that you launch it from the crontab. Let that sink in for a moment.. the fucking crontab. For initializing services. My whole life as a sysadmin was a lie. Cron is now an init system.

Fortunately that's about all I recall to be wrong with this thing. But there's a few things that I really want to tell any greenhorn developers out there... Always look at best practices. Never take shortcuts. The right way is going to be the best way 99% of the time. That way you don't have to go back and fix it. Do your app modularly so that a fix can be done quickly and easily. Store passwords securely and if you can't, let the user know and offer alternatives. Don't put it on the stdout. Always assume that your users will go with default options when in doubt. I love tweaking but defaults should always be sane ones.

One more thing that's mostly a jab. The ZNC software is hosted on a .in domain, which would.. quite honestly.. explain a lot. Is India becoming the next Chinese manufacturers for software? Except that in India the internet access is not restricted despite their civilization perhaps not being fully ready for it yet. India, develop and develop properly. It will take a while but you'll get there. But please don't put atrocities like this into the world. Lastly, I know it's hard and I've been there with my own distribution project too. Accept feedback. It's rough, but it is valuable. Listen to the people that criticize your project.

So... My parent's house is 40 years old.
I'm cleaning the corners... and my father as a DIY guy and a man that was never afraid to learn and update, there is so must useful junk, but also soooo many card boxes. He never throws them away, in case he needs to return the item.
So... I've been cleaning a 3 shelf open closet.
- have around 8 bags of cardboard, paper and newspappers for recycling.
- plus 2 bags of plastic.
- 4 bags filled with books for the local community center.
- a bag full of electronics to salvage.
And this only in 2 rows...
Man how could he store so much stuff in there I don't know, but this ends up being fun.
Also, one printer to salvage. :D
When it's over I get to own the shelf to store my stuff :D

I just wanted to develop a cool webapp-controlled lighting for my bar.

Next things I know, there is electronics scattered everywhere, 2 multimeters to find what the fck is wrong with a PSU not outputting 1/100 of the current it's supposed to, said PSU opened on my desk, and I'm trying to find a capacitor online because there isn't any fcking electronics store selling spare parts anymore in my city.

Context:
- PSU means Power Supply Unit, in this case a computer one.
- PSU was given by a friend and is out of warranty
- the total consumption for all LEDs is 24A @ 5V consumption. A refurbished PSU is ideal for that
- that PSU is rated 2A @ 5V on the stand-by, which is perfect to power a Raspberry Pi. The issue is that there is a sharp voltage drop as soon as you try to use more than 20mA.

!rant, more of an incredulous/cruelly amused "you had ONE job..."

so: biggest IT/PC/electronics store in my (and neighboring) country. their webpage, of course with the function to buy online, because of course.

the big green "Buy" button does nothing. doesn't work. doesn't react. I keep clicking it multiple times, shorter, longer, etc, because maybe their JS scripts are just shit so they slow.

nope.
okay. open devtools, JS console.
hover over the button: "Error: isMobile is not a function".
click the button: "Error: isMobile is not a function"

WAT.
search for isMobile in the script.
173 occurences.
fuck this.
console: isMobile = function(){return false;}
because I'm not on my phone.

click the "Buy" button.
works flawlessly.

...HOW?
THE WHOLE PAGE IS AN ESHOP YOU COMIC RELIEF INCOMPETENTS! =D

173 uses of non-existing function that blocks business-critical feature, THE ONLY CORE FEATURE FOR WHICH YOUR SITE EVEN EXISTS, and NOBODY, not the dev who fucked it up, NOT EVEN QA, noticed it??? =D =D

if I was the boss of the devs, or even boss of the whole company...
git blame
...and then i'd go the whole chain from the dev who caused the bug, through all of the QA people who "tested" that version before deploy, and I would personally, on the spot, fire each and every single one of them.

mainly because of who knows how much money this stupid not even a proper bug lost them.
but secondarily, because clearly none of those people give a single shit (n)or have an idea how to do their jobs.

=D =D

yeah but I was a good guy, filed a bug report in the "Complaints" section of their Contact form.
it goes to some call-center-like peon, so it starts with a sentence "forward this to your site's dev people outright to file as a bug, thank you".

but... HOW.... =D
HOW can you let something like this through? =D
the bottleneck of your whole user interaction, which forms first of the three steps OF THE MAIN AND MOST IMPORTANT FUNCTION of your whole business... =D
...I...
...does not compute =D

...BUT THEY USING ANGULAR, SO THEY ALL MODERN AND HIGH-TECH AND EVERYTHING'S FINE!!! =D =D

grrrr

last week my laptop died out of nowhere. it stopped recognizing the one drive in it. I lost a bunch of files, code. evidently ssds fail out of nowhere unlike hdds which slow down and error all the time before ultimate failure

my warranty for this 4k$ laptop expires in 12 months and this was month 13. nice. I don't like warranties anyway, and the site said they would replace things with "comparable hardware, sometimes refurbished" wtf no thanks

so I found some guides of people upgrading the drive in this laptop. seemed easy enough, unlike older laptops from back when I was in school where you had to take out 12 things first to get to anything
unfortunately I needed a specific screwdriver. I walked several miles to the nearby hardware store thinking they would have said screwdriver. the old guy in the basement said there was a kit where it started from t4 (I needed t5), but he had just sold out his last one. I checked their online store with a friend for a while on my way back home and we kept finding torx screws but the wrong sizes. fuck.
he said screwdrivers this small are only used for electronics, asked if there's any other hardware stores and there aren't near me
however it occurred to me this strip mall has a lot of suspicious computer stores on it. so I walked back up the street looking for one.
found one with a suspicious poster, saying it was an internet cafe but the last point on their poster said they do repairs. walked in. nobody is in there, suspiciously 2 desks with old computers all empty, then you go forward in this dark cave, with plastic wrapped implements on the walls, you finally find a glass shield and behind it was a meek Asian man that took me a moment to notice
I asked him if he had t5
he handed me a plastic baggy full of tiny screwdrivers, for me to take one
I asked if they're t5
the shape looked right, but I can't tell the size
I took one out and tried to find size marking, but nothing
he didn't seem to know what I was asking when I asked about its size
he said if it's wrong I can come back and trade what I took for another. lol
I asked him if I can buy it, since that wasn't evident to me due to how sus this random bag of screws is being thwarted on me lmao
he said 5$ cash
I gave him a fiver
this sus shop literally avoiding taxes lmao

walked back home, ate food cuz starving, tried the screw and FUCK, it's too big. put laptop in a bag and hauled ass fast, checked on maps the store I got this from closes in a few minutes so I really wanted to make it there because what if the receptionist changes and they don't know I took this screw. I got no receipt

got there right before closing, put my laptop down, said it was too big. he used a few screws until he found one that fit, said I could try it and I did (so scam aware!). bingo bango. now I got a screwdriver that fits the laptop.

walked home, sat down and took apart the laptop. been a few years since I did so. the hardware inside looks entirely unrecognizable to me. started cycling through YouTube videos of laptops of the same name as mine, but their insides don't look like mine. is this ram? is this the NVMe? what the fuck is anything?
finally found a video guide where the guy was quite informative. not the same laptop but he's informative enough I figure it out. ram and drives are so different and weird now. took parts out, put them back in, rebuilt laptop, tried to boot, same problem. jiggling parts like this works with desktops often, guess not with a failed NVMe

so I'm screwed. get on Newegg and bought a new NVMe. should arrive in 3 days via Purolator

yesterday was day 3. it was at a sort facility near me, then out on delivery, but nobody ever came. then it went back to sorting. now it's out on delivery again. I'm sitting here thinking that's a little weird, wasn't Purolator the delivery company that had me go 2 hours outside of town to pick up a 15lb desktop case once?

... and then I looked up Reddit comments... then reviews on the purolator facility it's at... I am screwed. last time iirc they were out for delivery for 3 days, never tried delivery, then on the last day at the end of day they stated they attempted delivery but no go. that was bullshit. then it ended up at that facility. which takes 2 hours to fucking reach.
the reviews are so bad... the facility has 1.2 star reviews with thousands of them. they won't leave even a stub, then seem to not know where your package is at the facility, or they deny you have the right to pick it up despite ample IDs, or someone ELSE picks it up and it's not there. they also ship your package back after 5 days, so if they don't leave a note and you miss it tough luck...

fucking hell
also rumours that they just hire "contractors" in normal cars to drop off packages? wat? lol
AND EVERY REVIEW HAS A BOT COMMENT. THEIR SUPPORT IS JUST A CHATBOT

I thought this was just a small hiccup
I think I might not have a drive for weeks now
fucking hell
now I'm sitting on my porch

So today at the electronics shop I saw an 500Gb on sale. For some reason it also came with a code for Battlefield 2042. The price label was written in a very confusing way, so I thought it was actually ~22EUR instead of ~118EUR off. It sounded too good to be true, but my train of thought was that it's entirely possible that they are really desperate to get people to play their shitty game.

Unfortunately it was too good to be true and it was actually actually 96EUR. What a scam.

In case you wanna look it up yourself, you can also find it online (For a lot cheaper than in that store). "WD_BLACK 500GB SN750 SE NVMe"

For some reason it's cheaper with the game, I wonder why (But it's still a tad overpriced)
