First time poster here. Please be nice :)
My biggest workaround is one that's being currently deployed to 40 truck drivers (trucking company here), preventing printers being out of usage while on the road. We also have to use HP ePrint to wirelessly print documents, but that's another story for another time I guess :)
CEO asked us to install wifi printers in our 40-ish trucks which has wifi on board. However he's always picking one of the cheapest options possible, so we got consumer grade printers (Laserjet 1002w). Those printers often disconnects without getting back on the truck wifi network EVER. I have to get physically in the truck, wire the printer via USB onto my laptop and reconfigure Wifi on it with the HP Windows tool. This means lots of printer downtime, which always happens when the drivers are three timezones away from our office
Then I thought: "What if I could sniff what HP sends via USB while I (re)configure the printer, and replay whats being sent later? Our trucks all have an Android tablet with a USB type-A connector with host capability, so I could write a small app that replays the config when plugged in by the user.
Three days of hacking around later, I have a working app. By chance, HP printers (or at least those models we have) uses HTTP POST via USB, so I could easily replay the request.
Edit: the end result is that truck drivers just plug the printer to their tablet, press "reconfigure" in a home made Android app, printer is reconnected to the truck and they're good to go. They don't have access to the network nor know enough to debug themselves anyways14 -
Today I discovered that we have a CSV export button for an order transaction system, on a page which is completely disconnected from the rest of the website.
It is only being called by an internal server, used by our Data department.
They run selenium to click the button.
Then they import the CSV into a database.
That database is accessed by an admin panel.
That admin panel has an excel export button.
Which is clicked by our CFO. But he got bored of clicking, so he uses IFTTT to schedule a download of the XLS and import it in Google Sheets.
That sheet uses a Salesforce data connector.
Marketing then sends email campaigns based on that Salesforce data...

So just recently my school blocked the following for unknown reasons websites
Github
Gitlab
Amazons aws
stack exchange
Bitbucket
Heroku
The hacker news
DuckDuckGo
The Debian package repositories yea all of em
And all domains that end in .io
Now some of you out there are probably just saying "well just use a vpn" the answer to that is I can't the only device I have a locked down school iPad can't install apps cannot delete apps cannot change vpn or proxy setting's I cannot use Safari private tab they have google safe search restricted to "on" they even have "safari restricted mode which lets safari choose what it wants to block" and even when I'm on my home wifi it's s still blocked as they use Cisco security connector THIS IS HELL
Also this is my first post :)30 -
so here's a little story:
yesterday i decided to buy a shiny new gtx 1070 since my pc is getting very old, i come back from the store and i realize that my case is slightly too small to fit the card.
'No bg deal' i think to myself, i run out to buy a saw and after some work i made some space to fit the card in by sawing off some hard drive bays i was not using. I plug in the card, i wire up the pc, and it does not boot: after some asking around (i have never really built a pc before), i relaize i need more power to the card and wire a second PCIE connector. low and behold, i power of the pc and it works! Once logged into windows tho, i realize none of my HHDs are detected...
To cut a long story short, i **did not think to unplug the hard drives before i started sawing off bits of the case and the vibrations killed both of them!** i lost ~1TB of data in the process: a lot of it was games and programs, but i have yet to tally up the damage.
I am completely bamboozled by what the fuck just happened, i think i'll go hand myself in to the nearest police station for crimes against technology... or maybe a mental clinic would be best?...
PS: my system drive was spared since its an SSD, but i may as well re-install windows at this point since i lost 90% of my software11 -
Year 2200, somewhere unknown. A robot drone flies above a now destroyed city. As it slowly descends down, it finds it's way into a building. In the rubble, a monitor is still flashing. The drone moves toward the monitor. After few minutes of analysis, drone releases a connector from it's belly. It connects to CPU nearby. After scanning the system for another few minutes, it's apparent the system was not the new OS which the Government released and Mandated. Rather, a prehistoric OS which legends spoke in hushed tones. An OS so powerful, which controlled then millions of computers.
Like the story so far? Should I continue?9 -
Things that still feel like they were yesterday:
- Microsoft buying Skype
- WiFi 802.11n
- USB 3.0
- Android 5.0, Material design
- Microsoft buying Nokia
- “Grid layout is an experimental technology”
Nobody even uses Skype anymore. I’m still looking for “is it support that WiFi n-word” when choosing a router. Yes it supports it. Everything that happened since 2009 supports it. Usb 3.0 was released in 2008, 12 years ago, and I’m still happy when it’s a blue connector instead of white. Android 5.0 was released 6 years ago.
I don’t understand HOW can I know that the newest but not exactly bleeding edge web specs like clamp function aren’t the newest and use them but still believe that grid layout is an experimental technology despite using it in production and FUCKING LOOKING AT CANIUSE TABLE and FUCKING THINKING THAT USB 3.0 WAS RELEASED JUST NOW while working on the laptop that FUCKING HAS TYPE C as its only port
It looks like somebody should go have his time perception module checked11 -
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 -
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 😑

Saw some cheapie little radio in the dollar store, bought 2 of them for reverse engineering. Powered it from my lab bench power supply as usual, and tested whether it actually works before doing anything else.. then I noticed that the tunes were actually quite catchy, so I just ended up listening.
Then I started to notice that the audio wire I was using (the one I've spent a couple of days building earlier) had intermittent audio issues where the right driver would drop out when the wire was held in certain positions. Oscilloscope probing showed that there was some sort of disconnect, with only the 50Hz noise from the power lines showing up. Opened up the connector and noticed that the ground wire had detached. An 28AWG electrical wire that was inside a jack that was meant for stress relief! Yet the copper strands must've detached one by one regardless. What do I need then, huh?! 18AWG which wouldn't even fit on the connector, only to see the strands in that eventually detach as well?! You know what, let's go fancy.. 1AWG which is meant for extremely high current applications!!
At that point I was literally shouting "FUCK!!! Why does this shit always happen to me?!! ONE FUCKING PROJECT THAT FINISHED SUCCESSFULLY, YET STILL BROKE?!!!! WHY!!!!!!"
Clearly I need some fresh air to cool down. On my way to the fast food restaurant to get some Bicky burgers. More shit, humans. One stupid driver who slowed down on me, which of all things I hate the most. GO FASTER ALREADY YOU SLOWFUCK, AND GET THE FUCK OUT OF MY SIGHT!!! Next a pedestrian with a dog.. I swear motherfucker, if that dog comes anywhere near me I'll personally turn it into fucking fricassee.
Ah and then comes the killer.. in this stupid fucking summer, all that's needed to fix any issue is a fucking stupid DESPACITO, right?! More like DeSPASTICo!! FUCK!!!!
.. Back home, rather tired. So essentially a wire that was specifically built to have high endurance broke on me. Back to Bluetooth I guess.2 -
*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 -
Why do people insist on moving stuff on my desk!
I've very particular about my desk, have my monitors, laptop stand, stands for devices etc. setup the way I like them, and every so often someone sits at my desk when i'm not in and just shoves everything around.
Last company I worked for, I came back from holidays to a thunderbolt cable, the connector of which, had been crushed under the wheel of a chair, because someone left it on the floor.
... Is it wrong or not "proper", to send around an email saying the next person to touch my stuff gets stabbed?10 -
You know that the mobile ecosystem is completely fucked when you have to open up your device just to do a hard power cycle.. and what for? What's the fucking difference between a connector inside of the device, and one that's outside the device? A couple of cubic millimeters? If it's even that much?

iPhones are ridiculously picky when it comes to finding a mate- um charger. And knowing why doesn't really make it any easier to understand why. If anything it baffles me more.
So, let's start with appliances that are not phones. Think Bluetooth headsets, keyboards, earbuds, whatever. Those are simple devices. They see 5V on the VCC line and 0V on ground, and they will charge at whatever current they are meant to. Usually it will not exceed 200mA, and the USB 2.0 spec allows for up to 500mA from any USB outlet. So that's perfectly reasonable to be done without any fuss whatsoever.
Phones on the other hand are smarter.. some might say too smart for their own good. In this case I will only cover Android phones, because while they are smarter than they perhaps should be, they are still reasonable.
So if you connect an Android phone to the same 5V VCC and 0V ground, while leaving the data lines floating, the phone will charge at 500mA. This is exactly to be within USB 2.0 spec, as mentioned earlier. Without the data lines, the phone has no way to tell whether it *can* pull more, without *actually* trying to pull more (potentially frying a charger that's not rated for it). Now in an Android phone you can tell it to pull more, in a fairly straightforward way. You just short the data lines together, and the phone will recognize this as a simple charger that it can pull 1A from. Note that shorting data lines is not a bad thing, we do it all the time. It is just another term for making a connection between 2 points. Android does this right. Also note that shorted data lines cannot be used to send data. They are inherently pulled to the same voltage level, probably 0V but not sure.
And then the iPhones come in, Thinking Different. The iPhones require you to pull the data lines to some very specific voltage levels. And of course it's terribly documented because iSheep just trying to use their Apple original white nugget charger overseas and shit like that. I do not know which voltage levels they are (please let me know!), but it is certainly not a regular short. Now you connect the iPhone to, say, a laptop or something to charge. An Android phone would just charge while keeping data transmission disabled (because they can be left floating or shorted). This is for security reasons mostly, preventing e.g. a malicious computer from messing with it. An iPhone needs to be unlocked to just charge the damn thing. I'm fairly sure that that's because the data lines need to be pulled up, which could in theory enable a malicious computer to still get some information in or out of it. USB data transmission works at at least 200mV difference between the data lines. It could be more than that. So you need to unlock it.
Apple, how about you just short your goddamn data lines too like everyone else? And while you're at it, get rid of this Lightning connector. I get it, micro USB was too hard for your users. I guess they are blind pigs after all. But USB-C solved all of that and more. The only difference I can think of is that the Lightning connector can be a single board with pads on either side on the connector, while in USB-C that could be at the socket end (socket being less common to be replaced). And at the end of the day, that really doesn't matter with all the other things that will break first.
Think Different. Think Retarded. Such tiny batteries and you can't even fucking charge them properly.6 -
What if my connector doesn't want to group itself into male or female on either end? how am I supposed to connect it then.

Yesterday I did some experiments with my lab bench power supply to see if everything was working as it should, and whether my newly acquired laptop (old business laptop from 2004) would still power up. Noticed that it did, and left the thing charging for a while - its battery was completely drained. But after letting it sit for a few hours, one of my switches wouldn't turn off anymore.
The lab bench power supply has a 250V 2.5A (625W) rated switch on the AC side, connected to a 50V 10A (500W) AC-DC power supply. The DC side of that is then connected to 2 DPS5005 units, of which one was driving 50W of power into the laptop.
The experiment went reasonably well, the AC-DC power supply was loud but stayed cool like a cucumber. The switch however wouldn't turn off anymore after a few hours. Today I've desoldered that and put on a new one, and did a failure analysis. Turns out that it was a rocker switch (so there's a little nub in there that moves a piece of metal back and forth) and that the contacts of the switch (the piece of metal and the inside of the connector piece) were welded together.
However, the only thing that I know of that causes this welding is when loads are switched off, and an arc is generated. This wasn't the case here - it was just kept on for a couple of hours, with (accounting for power losses across the circuits) 80W going through it at most. I never expected that to cause a weld. Any clue as to why this happened? It really boggles my mind, and I don't want the switch that's currently in there to face the same fate.12 -
EoS1: This is the continuation of my previous rant, "The Ballad of The Six Witchers and The Undocumented Java Tool". Catch the first part here: https://devrant.com/rants/5009817/...
The Undocumented Java Tool, created by Those Who Came Before to fight the great battles of the past, is a swift beast. It reaches systems unknown and impacts many processes, unbeknownst even to said processes' masters. All from within it's lair, a foggy Windows Server swamp of moldy data streams and boggy flows.
One of The Six Witchers, the Wild One, scouted ahead to map the input and output data streams of the Unmapped Data Swamp. Accompanied only by his animal familiars, NetCat and WireShark.
Two others, bold and adventurous, raised their decompiling blades against the Undocumented Java Tool beast itself, to uncover it's data processing secrets.
Another of the witchers, of dark complexion and smooth speak, followed the data upstream to find where the fuck the limited excel sheets that feeds The Beast comes from, since it's handlers only know that "every other day a new one appears on this shared active directory location". WTF do people often have NPC-levels of unawareness about their own fucking jobs?!?!
The other witchers left to tend to the Burn-Rate Bonfire, for The Sprint is dark and full of terrors, and some bigwigs always manage to shoehorn their whims/unrelated stories into a otherwise lean sprint.
At the dawn of the new year, the witchers reconvened. "The Beast breathes a currency conversion API" - said The Wild One - "And it's claws and fangs strike mostly at two independent JIRA clusters, sometimes upserting issues. It uses a company-deprecated API to send emails. We're in deep shit."
"I've found The Source of Fucking Excel Sheets" - said the smooth witcher - "It is The Temple of Cash-Flow, where the priests weave the Tapestry of Transactions. Our Fucking Excel Sheets are but a snapshot of the latest updates on the balance of some billing accounts. I spoke with one of the priestesses, and she told me that The Oracle (DB) would be able to provide us with The Data directly, if we were to learn the way of the ODBC and the Query"
"We stroke at the beast" - said the bold and adventurous witchers, now deserving of the bragging rights to be called The Butchers of Jarfile - "It is actually fewer than twenty classes and modules. Most are API-drivers. And less than 40% of the code is ever even fucking used! We found fucking JIRA API tokens and URIs hard-coded. And it is all synchronous and monolithic - no wonder it takes almost 20 hours to run a single fucking excel sheet".
Together, the witchers figured out that each new billing account were morphed by The Beast into a new JIRA issue, if none was open yet for it. Transactions were used to update the outstanding balance on the issues regarding the billing accounts. The currency conversion API was used too often, and it's purpose was only to give a rough estimate of the total balance in each Jira issue in USD, since each issue could have transactions in several currencies. The Beast would consume the Excel sheet, do some cryptic transformations on it, and for each resulting line access the currency API and upsert a JIRA issue. The secrets of those transformations were still hidden from the witchers. When and why would The Beast send emails, was still a mistery.
As the Witchers Council approached an end and all were armed with knowledge and information, they decided on the next steps.
The Wild Witcher, known in every tavern in the land and by the sea, would create a connector to The Red Port of Redis, where every currency conversion is already updated by other processes and can be quickly retrieved inside the VPC. The Greenhorn Witcher is to follow him and build an offline process to update balances in JIRA issues.
The Butchers of Jarfile were to build The Juggler, an automation that should be able to receive a parquet file with an insertion plan and asynchronously update the JIRA API with scores of concurrent requests.
The Smooth Witcher, proud of his new lead, was to build The Oracle Watch, an order that would guard the Oracle (DB) at the Temple of Cash-Flow and report every qualifying transaction to parquet files in AWS S3. The Data would then be pushed to cross The Event Bridge into The Cluster of Sparks and Storms.
This Witcher Who Writes is to ride the Elephant of Hadoop into The Cluster of Sparks an Storms, to weave the signs of Map and Reduce and with speed and precision transform The Data into The Insertion Plan.
However, how exactly is The Data to be transformed is not yet known.
Will the Witchers be able to build The Data's New Path? Will they figure out the mysterious transformation? Will they discover the Undocumented Java Tool's secrets on notifying customers and aggregating data?
This story is still afoot. Only the future will tell, and I will keep you posted.6 -
You know what's rocket science? Serial ports.
Every freakin' datasheet states RX/TX but not from which side of the connector. Some look at it from the inside (RX for own receive), some from the outside (RX for receive of the counterpart). But never ever try to explain what is what, that would be too easy.
On literally any first attempt of connecting devices in my life it was wrong. And then you switch 'em and it's still wrong. Then you switch again, and it may work. Or you have to switch a few times more, you never know.
Those freaking bastard interfaces from hell.4 -
Fuck M.2 and mSATA SSD's. Not only do you have to worry about lengths (30, 42, 80mm), but then there's mSATA vs M.2... Where SSD's with an M.2 connector can STILL use mSATA internally! AND on top of that there's a bazillion connector types. For that I'll let the attached image speak for itself. I don't see the difference to be honest. Maybe someone in the comments can explain.
Long story short, I bought what looks to be an M.2 SSD that nonetheless uses mSATA and I pretty much wasted my money on a paperweight. The little enclosure I bought for it only does mSATA *connectors*. It doesn't fucking fit!

I am on vacation from my full time job this week. I wanted to use this week to write a PoC for a potential customer of my side business. really interesting project for me.
potential customer is a window and door manufacturer and needs an application to manage their racks.
their ERP system already has a simple rack management but it is only useable in house.
they want the drivers to be able to scan racks they deliver to a customer with a native app and they want to have a webapp for the customers to see racks that are assigned to them as well as reporting a rack ready for collection. And that all needs to be in sync with their local ERP system.
as i am a .net guy i decided to go with the abp framework (because it got recommended to me) and xamarin for the native app part (because i have experience in this).
i have now spent 4 days implementing this and it has been so rewarding. the framework is so powerful and it's template saved me endless hours.
i even wrote a very basic connector service which synchronizes data between my app and the clients ERP system. Just one way until now because of time issue, but i learned to scaffold an ef core with db first. It is noticable that the ERP system is 2-tiered - meaning the clients directly talk to the db.
Tomorrow i will implement the xamarin client.
4 days just coding what i want to. choosi g my own velocity and making my own priorities without any interruptions or discussions and a bunch of new things to learn.
Probably wasted half a day because of stupidy (implemented some bugs) but fixing and learning is part of the journey and i lime that part, too.
i am so relaxed right now 😁 just wanted to share this without a real reason :P3 -
FUCK YOU NBN.
It's taken this shit company 6 "Specialist" technicians and almost 2 months to identify that the connector from the mainline to the multiport is not aligning. Now I have a planned remediation date of the 15th October.
Possible 6 months without internet. FML18 -
So our new hardware guy who is being managed by our lead embedded developer had the task of designing me an expansion board for my Linux board. The Linux board uses the 40 pin expansion like the raspberry, bananna and orange pi family and as you all know there are many different types of expansion boards for this.
I said at the start come to me and tell me what you want to connect to before deciding which pin you connect to so it is less work for me with Linux board configs and drivers.............
No no no we will sort it all... erm.....
So today they come ask me if they can use an SPI port for GPIO and I am like erm... why there is plenty of GPIO...
It turns out they have been designing the board based on the pin outs of an expansion board and not the actual connector of the Linux board.. I mean seriously WTF!1 -
WordPress uses 25+ MySQL connections per person. MySQL limit is set to 100. 4 people can bring down a critical component of the company. Only fix is to write custom MySQL connector using PDO and persistence connections. Added a Resistor cache just for good measure.8

## Building my own router
Damn it! I've got to read more before making decisions :) I already do that, but I need yet *MORE* reading.
So I bought a miniPC which I'm planning to turn into a router. I wanted to install AX200 (wifi6) card in it but it could only see the bluetooth part of it (using btusb kernel module).
What I did NOT know about wifi cards and mPCIe slots
M2 is only a form-factor. It defines what the connector looks like. Over that connector multiple different protocols could be used. m2 (NGFF) WIFI cards are usually using PCIe proto. And USB.
https://delock.com/infothek/M.2/...
My so-desired AX200 uses both PCIe and USB protocols: USB for BT and PCIe for the actual wifi.
https://ark.intel.com/content/www/.... The same spec applies to both: m2 and mPCIe card versions.
Now my mini PC has a mPCIe slot but the label on the board says "USB wifi". Which suggests that it only accepts the USB-related pins of mPCIe (as wiki says about mPCIe: "The host device supports both PCI Express and USB 2.0 connectivity, and each card may use either standard.").
So I guess that means I'm stuck with a useless mPCIe port :D shit..
Now my best bet is to wait for USB dongles supporting wifi6 and use usb AC adapters until then. Well... It's not an optimal outcome. But still IMO a better solution than an embedded router from the shelf!
(No, I'm not giving up and buying another used/new PC :) )
At last I can calm down and stop searching for magical pcie-to-usb adapters :) Phew... That's a relief!1 -
Didn't want to go to my router and disconnect it to reset, so I've just cut the power with the breaker, I do really hate that power cable positioning on the router body, so much that the breaker is actually a good 15 feet more to walk, but saved me from having to fiddle around with that barrel connector.16

Situation:
Php not loading oci8 connector for oracle database in windows server, got the all famous and feated oci_connect unknown function error.
Solution:
Check to make sure that the stupid dll is in the extensions folder ---> check
Check to make sure that the extension_dir path is done properly inside php.ini ---> check
Ensure that extension=php_oci8_11g.dll is inside php.ini ---> check
I have no fucking clue why this piece of shit would stop working all out of the sudden and would not fucking work. But here i am yet AGAIN trying to fix something for the fucking web tech department because their fucking lead dev is out.
I
Fucking
HATE
Having to deal with php configurations. Such a fucking pain in the fucking ass man.
FUUUUCKING WOOOOOORK8 -
If you also programm in your free time you probably know this kind of situations.
Situation: I'm currently creating my own PHP framework (I know there are plenty... I do it for "fun").
The database Connector Class wasn't working so after an eternity (around 2h) I just went to bed.
11pm: My Eyes open. I'm sure I just solved the problem in my dreams. (Spoiler alert: I didn't)
2am: I go to bed again. It didn't work.
Next day: I open the file add a missing required file. It works. I'm now tired AF and feel like dying and above all: I now get all the suicide PHP memes. Good night guys. I'm getting some sleep.3 -
FML I am an idiot.. might end up in a rant here (well deserved!!) //if you are here reading this I'm so sorry again!!
I wrote to our support I need DP/HDMI cable.. they asked me to take a pic of the cable I'm currently using.. WTF?! Don't you know how connectors look?! Just get me the damn cable.. :/
Ok.. Took a picture.. sent it back.. At that time I still didn't see the problem with what I wrote/demanded..
Got back reply this is not HDMI connector... FML, I was so convinced computer had HDMI ports so even when I took the pic I wasn't paying attention.. Fuck.
And before when I was switching cables behind the computer below desk I was just blindly feeling around, it didn't even occurr to me to actually check what connectors are used..just knew both monitors had the same connector (and not aure why I thought HDMI :/)...so yeah, I'm the idiot who is not paying attention to stuff.. Fuck.. Was on a scavanger hunt for a wrong type of cable the whole time.. Sorry again!! And please don't kill me next time you see me.. o.O1 -
Last week I wired up my home network (including custom modem and routers) myself, because the stuff my ISP wanted me to use was garbage.
Luckily Germany has "router-freedom" so ISPs are not allowed to force us to use their device to dial into the network.
I did everything myself, because the 'technicians' they kept sending me were just idiots who didn't know anything, considering the highly paid job they are doing. Usually they told me, to get the device from my ISP, because my "Router" (actually a business grade, standalone Modem by Cisco, to feed my Router) didn't even have WiFi ( lol ). Also all Technicians didn't arrive at the agreed date but at some other time. I wasn't able to wait any longer.
So I did it myself.
Consider me something more like a student of theoretical computer science. Not actually supposed to be experienced with hardware stuff.
The ISP is serving me with a DOCSIS 3.0 Network based on the television cable network in my city. For some reason they are providing the internet-access to only one socket in the apartment, which has a rather uncommon "WICLIC" connector. After having trouble getting an adapter for WICLIC to common coaxial F-Connectors (used by every DOCSIS-Modem), I made one myself.
After setting up everything (not that hard, once the connectors fit) my modem told me, that, while I'm perfectly connected to the ISPs internal Network, I still can't access the internet.
So I called the ISP...
After getting ranted at, about that what I'm doing is illegal and only certified employees are allowed to do this and I will break more, than actually do good and that I can't just connect my own "Router" (again I needed to correct her: Modem) I hang up the phone.
Also she accused me of hacking their devices because I'm not supposed to see my IP address... (My Modem told me on its web interface. I didn't even need telnet for that.)
I went to the ISPs head office, told the first desk as many technical terms as I could remember and got forwarded to something like the main technician.
He was a really nice guy. The only sane and qualified person I dealt with at this company. He asked me for my Address and Device Model, I told him my MAC and last internal IP, I had seen and he activated my internet access within a minute.
We talked a while about the stupid connector that ISP is using in the homes and he gifted me some nicer adapters to connect my modem to the wall.
Why do ISPs hate their customers that much?2 -

I've been working on this fucking instagram connector for 4 weeks now, mainly due to idiotic red tape
Now the time has come to get it approved. I'm supposed to let them know how to test the connector with a test user. but FUCKING facebook's test users don't even work as test users! their own spam catcher identifies their own test users as bots!!!!
I mean what the fuck!!!! HOW AM I SUPPOSED TO GET THIS APPROVED IF YOUR TEST USERS DON'T FUCKING WORK AS PART OF THE TESTS
AAAAAAAAAAAAA THIS IS FUCKING INFURIATING3 -
The ridiculous and shameful story of how simply "installing Windows" saved my hard drive from the garbage.
(Also update on https://devrant.com/rants/3105365/)
It started with my root partition turning read-only all of a sudden. Some quick search suggested that I should check the sanity of my hard drive, by running a SMART test, which failed of course. I backed up my data using ddrescue and ran a badblocks over the whole thing, which found around 800 unreadable blocks in a row. I was ready to bid farewell to my drive, but as a last resort, instead of the trash, I brought it to this place where they claimed they can repair the damaged hard drives by "surgery".
To my surprise, they returned my drive the next week, saying it is all well now, and charged me 1/8 the price of a new drive, with a refund guarantee if there was a problem in two days. There was a problem right there: I ran another SMART test which failed again, and also the faulty blocks were still unreadable! So I stormed the place and called for my refund, showing the failed SMART report. The only answer I would get from the staff was "Have you tried installing Windows?".
I usually try to be patient in such situations; I really don't like to declare publicly that "not everyone uses that stinky piece of rotten software you call an OS", but their suggestion seemed totally irrelevant! I got all types of IO errors all over the damn thing and they told me to install Windows. Why? Because this was the only test they would rely on. At last I managed to meet the "technician" there and showed him the IO errors: tried to read the bad sectors with dd and failed. He first mumbled somethings like "Have you checked the connector?" or "Are these the same blocks?", but after he ran out of bullshit, he said "Why don't you just install Windows first and see if that helps?" and I was ready to explode in his face!
"You test drives by installing Windows, just because it will make a nasty NTFS partition and probably does an fsck? If you shut your mouth for a sec and open your eyes you'll see this is a shit load of IO errors we got here: You can't install Windows, you can't even make an NTFS here, because it will try to zero-the-fuck-out the damn partition and it will face the same fucking IO error that I'm showing you right now in almost one single fucking system call!"
"I don't know this kind of test you are using. We have our own tests and they've passed successfully. So all I can do is to give you a Windows CD if you want."
"I don't need a Windows CD. I will just try to make an NTFS partition on the error spot and I will fail."
"Ok. Then call me when your done."
I was angry, not only because I felt they're just trying to avoid a refund, but also because I knew I've lost my drive. But just with hope that I could get my money back, I made a small partition over the error spot and ran `mkfs.ntfs` on it. I was ready to show the failure to the guy, but I looked more precisely and saw that "the filesystem was created successfully!" I was sure something is nor write. I then successfully mounted the new partition, write over it and read it again. I even dd'ed the blocks again, and this time there was no IO error. All of a sudden everything was fine.
I didn't know what happened. Maybe it just needed a write, while I'd just tried to read from those blocks. But anyway, I didn't called the technician guy again. I just thanked one of the staff there and said that my problem was solved. I then ran a successful SMART test and then restored my backup. Ridiculous like that.
I'm still not sure if my drive will continue to live with no more problems. I also have no explanation for what happened. (I appreciate any help on this https://superuser.com/questions/...) But I really like to see the look on the poor guy's face when he finds out that trying to install Windows just saved my ass!11 -
Today's accomplishments:
- Actually got the fuck out of bed this morning
- Fixed the RCA connector on the CRT I got from a friend (I got scared while discharging it but it turned out fine). Basically the metal piece that carries the signal through the connector was bent to hell and sticking out, so I desoldered it, bent it right again, put it in, and resoldered it.
- Went to taco bell twice within 8 hours
- Sat and talked with a couple friends for like 2 hours after school
- Met and briefly talked to a very cute girl that my friend introduced me to. She has colored hair (I REALLY like colored hair) and she vapes. So perfect girl for me.
- FINALLY FUCKING STARTED LAUNDRY
Things I didn't accomplish today:
- Working on the web page I posted about this morning
- Getting to school on time (ONE DAY I WILL)
- Staying in school once I was actually there (left during my 6th period to go to taco bell the second time, first time today was in the morning after I was already late to school cause they won't let me into class if I'm late)
- Fixing the boot errors on my laptop (sometimes when I boot it fucking freezes after flushing the journal, I've been trying to figure it out for a while but I have no fucking clue)
- Figuring out why my PS2 doesn't want to recognize controllers or memory cards (got a new motherboard and now it just isn't recognizing the controller/memory card, I feel like some of the traces broke at some point while it was apart??)1 -
First job and first days, boss comes to me with an urgent matter she nor other people were able to solve per her own words, it was something I hadn't even used before, a bug on a migration from versions between SSDTS projects, so she asks if I knew the technology, I answer no, but I'll try, so I started watching some tutorials and got hands on the project to know what it tried to accomplish, then in a couple of hours I found the bug in a connector it had with some other tech through a driver. Team went semi crazy like woah how you found that so quick, Bla blah... It felt good

Years ago when I was a kid I was into making things to solve problems. Earlier in my life I remember as a kid seeing a neighbor shove 120VAC into the ground to get worms to come up to the surface. I also remember taking a worm and slapping it on one of the posts and shocking the shit out of myself. Apparently that lesson did not stick.
As a teenager I wanted a device similar to this. So I wired a 120VAC plug and cord to a 1/4" audio connector. I threw this in a box and forgot about it. Years later my sister went through my things looking for a power plug for a synthesizer we had. It had an audio 1/4" plug for headphones. She told me she plugged this cord she found of mine into the synth and it started smoking. She went to pull the plug out and shocked the shit out of her. I don't think that the synth ever worked correctly after that.
Well, today I was thinking fondly about that story. I mean, who wouldn't think fondly about shocking the shit out of your sister (she didn't die, so its okay). However, it was dangerous. Really really dangerous.
The lesson I can take from this memory is this: if you know a software interface (or electrical) is not safe then don't build it. Someone will try and use that shit years later and really fuck some stuff up. I have to wonder. What kind of software traps have I built in the past that are yet to be discovered?3 -

Very excited, got my raspberry pi zero working over usb finally, gotta admit it took me a while to figure it out that the ifconfig IP assigned to the interface established isn't actually the raspberry pi's (seriously you don't want to see how far the visited google links go for all variations of "how to setup the otg ssh connection"), that only came to me once I was able to find the mini-hdmi to hdmi cable, before that it was a pure shitfest:
First I just tried all sort of configs, but the raspberry pi kept denying the ssh connection, slammed the microsd into my bigger Pi, even multiple times ran raspi-config, forced ssh to start in all possible ways, nothing.
Then I tried to use the TV-output on it together with my old small portable tv to maybe see some error-logs or the ssh not starting on the zero for whatever reason, even flashed a 2016 image thinking it is stretchs fault for not working, but then my fucking soldering iron cable disappeared, tried to quickly create my own, but that failed cause the 3.5mm connector it uses is different from the ones I had available, so I macgyvered a sketchy ass lose connection with male headers sticking through from the bottom and being sticked against the board with a female end on top, but the TV output wouldn't work, even with proper config options, so I gave up.
Some days later I've found the cable, connected it and realized the fucking IP it gets assigned is totally different from the interface, well fuck my life.
Atleast now I can make a clean image of that microSD and setup the portable laravel development raspi as I wanted, can't wait to try it once I get more time to fully set it up - btw even the internet bridge worked right out of the box, so I can easily use my laptops internet connection on the zero.9 -
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 !

Story, !rant.
So after previously telling the story of my laptop in the rain, I thought I should follow up with this one. (this is couple months later)
My laptop was bought second hand by my father (who doesn't know anything about computers) and the poor thing had a tendency to overheat. It worked fine, but under heavy load it would only last a couple minutes before it shut down.
So once I was cleaning out the fan (as dust accumulated in there) and I ran it under the tap, to get everything off. Sure, you might cringe at the idea but I thought some water wouldn't hurt it, especially after surviving en evening in the rain. So I cleaned it and let it dry.
A while later, when it finished drying I started to reassemble my laptop. After about 30 mins of fiddling with it, it was back together and ready for a fresh start! So I powered it on.
Sparks flew. Smoke started coming off the motherboard. More sparks.
😯
I pulled the cord. "Fuck, glad I caught it on time..."
I waited a while longer. Turn it back on. "Fan is not functioning properly or is missing". FML. After all it had survived, a bit of water in the circuit that made the fan spin is what took it down 😑
Fast forward two years (without a fan, shitty days), and I bought a second hand Lenovo laptop that I adore. So I thought I'd sell the laptop on Ebay, but first I should fix the fan so that I wouldn't have to sell it for next to nothing. Part number was hard to find, and bought it from somewhere in Europe. Four weeks later, the fan arrived at my doorstep.
Took the laptop apart (have I mentioned how hard that was?) and replaced the fan. Felt good to fix what I had ruined two years back. Put it back together (after applying thermal paste, I'm not a monster) and powered it on.
"Fan is not functioning properly or is missing"
😑
After checking the connection a couple times, I realized that what had given out was the motherboard connector for the fan, after the water incident. Wasted 40 dollars and several hours of my time for nothing.
The laptop that survived hours in the rain was taken down by a wee bit of water. So sad.2 -
It pisses me off so much when companies sell their products with non standardized charging ports. I bought a no name beard trimmer some time ago, lost the charger and obviously I cant find a replacement because I have no fucking clue what connector it is. The description of the trimmer mentions nothing. Fucking bs that is! -__-"

Hello! Do you have any idea how I change the connector of a ps/2 keyboard to USB? I've tried the following schematics that make sense but no success. When I plug in the keyboard the LEDs light up for about half a second and then turn off and the keyboard doesn't work.

Friday so not much happened except after switching mysql connector it turned out mysql-connector-python can’t handle blobs properly.
Funny that answer on SO is not to use it.
https://stackoverflow.com/questions...
It’s not obvious cause all you get is error when selecting from table that have blob.
Also I bought two books full of slavic bestiary drawings and descriptions of monsters.
Those drawings are pretty cool. I plan to try to make low polygon model from one of the drawings using blender 2.8

Need your help!
Tldr: how do I build a system with 2 power supplies so that I can power it from either one?
I'm currently working on a "video editing van" for an upcoming project and I found awesome atx power supplies that you can use on your normal car power source. Something like this: http://powerstream.com/DC-PC-12V.ht...
Here is where it gets tricky: obvioisly it would be easy to build a dedicated system for this purpose but I want to use an existing system with an existing psu. I still want to use the pc normally at home with the standard psu but don't fell like switching every single power connector everytime I take the pc into or out of the van. Do you have any idea how to make some sort of switching mechanism so that I can leave the Hardware as it is and just power it of any of the two psus?
Thanks in advance!8 -

Have anyone worked on anything like a form builder like by giving a name generating a table with default columns and new folder for controller , models inheriting a base class that can provide a CRUD functionality ?
In my company they have a cool module builder that allow you to add any field email ,file, password,connector field - connect two modules one 2 one relationship clonable field many to many built on php.
I tried and created one using python Flask framework but without restarting app the routes are not getting registering asked in stack overflow got downvoted
Any thoughts?3 -
Wow I just thought I had lost my good old friend forever - my laptop did not want to turn non anymore and since the main fan is somewhat broken, I thought I'd never see him alive anymore and that he died from overheating thus I opened it, plugged it to the power connector and voila, it works again - whew, that was a shocking moment for me and I guess it's finally time to replace that fan.7

Can anyone please help me troubleshooting my PC? My PC won't boot even to BIOS. This happened several times in the past but usually jiggling the cables would do the trick, this time it doesn't.
What happened: PC powered up, power light went on, all fans turned on just fine, hdd light turned on for a few seconds before turning off, monitor didn't catch any signal from the HDMI
What I have tried with no luck:
- unplugged and replugged SATA cables, fans, mobo 24 and 8-pins connectors
- moved the harddisk to another SATA and power connector
- flushed the CMOS memory
- removed RAMs
- unplugged speaker, keyboard and mouse
- switched it on without the HDD connected
Any suggestions?9 -
