Frack he did it again.
In a meeting with the department mgr and going over a request feature *we already discussed ad nauseam* that wasn’t technically feasible (do-able, just not worth the effort)

DeptMgr: “I want to see the contents of web site A embedded in web site B”
Me: “I researched that and it’s not possible. I added links to the target APM dashboard instead.”
Dev: “Yes, it’s possible. Just use an IFrame.”
DeptMgr: “I thought so. Next sprint item …what’s wrong?…you look frustrated”
Me: “Um..no…well, I said it’s not possible. I tried it and it doesn’t work”
Dev: “It’s just an IFrame. They are made to display content from another site.”
Me: “Well, yes, from a standard HTML tag, but what you are seeing is rendered HTML from the content manager’s XML. It implemented its own IFrame under the hood. We already talked about it, remember?”
Dev: “Oh, that’s right.”
DeptMgr: “So it’s possible?”
Dev: “Yea, we’ll figure it out.”
Me: “No…wait…figure what out? It doesn’t work.”
Dev: “We can use a powershell script to extract the data from A and port it to B.”
DeptMgr: “Powershell, good…Next sprint item…”
Me: “Powershell what? We discussed not using powershell, remember?”
Dev: “It’s just a script. Not a big deal.”
DeptMgr: “Powershell sounds like a right solution. Can we move on? Next sprint item….are you OK? You look upset”
Me: “No, I don’t particularly care, we already discussed executing a powershell script that would have to cross two network DMZs. Bill from networking already raised his concern about opening another port and didn’t understand why we couldn’t click a link. Then Mike from infrastructure griped about another random powershell script running on his servers just for reporting. He too raised his concern about all this work to save one person one click. Am I the only one who remembers this meeting? I mean, I don’t care, I’ll do whatever you want, but we’ll have to open up the same conversations with Networking again.”
Dev: “That meeting was a long time ago, they might be OK with running powershell scripts”
Me: “A long time ago? It was only two weeks.”
Dev: “Oh yea. Anyway, lets update the board. You’ll implement the powershell script and I’ll …”
Me: “Whoa..no…I’m not implementing anything. We haven’t discussed what this mysterious powershell script is supposed to do and we have to get Mike and Bill involved. Their whole team is involved in the migration project right now, so we won’t see them come out into the daylight until next week.”
DevMgr: “What if you talk to Eric? He knows powershell. OK…next sprint item..”
Me: “Eric is the one who organized the meeting two weeks ago, remember? He didn’t want powershell scripts hitting his APM servers. Am I the only one who remembers any of this?”
Dev: “I’m pretty good with powershell, I’ll figure it out.”
DevMgr: “Good…now can we move on?”

GAAAHH! I WANT A FLAMETHROWER!!!

Ok…feel better, thanks DevRant.

We moved to a new office floor and got a brand new set up. My new extension monitor died just after 4 hours of use, it was showing a black screen a with couple of colourful lines running down the screen.

Got the IT guy to come and replace it. He says he must test it with a display cable even though the screen was dead without any input source. (Ok fine cbf arguing with you, just do it.)

*Magicarp used splash, nothing happened*

Realising I was right, he gave the ok for another guy to replace my monitor.

Second guy comes to my desk and realised he forgot the electric screwdriver. (Sigh, how long must I wait...) After he finally finished installing​ the new monitor he plugged the display cable into a random display port without looking.

*Magicarp used splash, nothing happened*

Since the monitor wasn't displaying anything, he jumped into asking me to restart my computer. I gave him "the wtf are you stupid face" and just said "NO". I looked over to where he plugged the cable and asked why he plugged into the "dp out" port.

I plugged the cable to the correct port and monitor was working.

Felt like I can do their job better without any experience in IT support.

PS. Don't play the "please restart your computer" card on me. I also work in technology.

Mind blown when I realised the Display Port “D” also contains a “P”.

So yesterday our team got a new toy. A big ass 4k screen to display some graphs on. Took a while to assemble the stand, hang the TV on that stand, but we got there.

So our site admin gets us a new HDMI cable. Coleague told us his lappy supports huge screens as he used to plug his home TV in his work lappy while WFHing. He grabs that HDMI, plugs one end into the screen, another - into his lappy and

.. nothing...
Windows does not recognize any new devices connected. The screen does not show any signs of any changes. Oh well..

Site IT admin installs all the updates, all the new drivers, upgrades BIOS and gives another try.

Nothing.

So naturally the cable is to blame. The port is working for him at home, so it's sure not port's fault. Also he uses his 2-monitor setup at work, so the port is 100% working!

I'm curious. What if..... While they are busy looking for another cable, I take that first one, plug it into my Linux (pretty much stock LinuxMint installation w/ X) lappy,

3.. 2.. 1..

and my desktop is now on the big ass 4k fat screen.

Folks. Enough bitching about Linux being picky about the hardware and Windows being more user friendly, having PnP and so. I'm not talking about esoteric devices. I'm talking about BAU devices that most of home users are using. A monitor, a printer, a TV screen, a scanner, wireless/usb speaker/mouse/keyboard/etc...
Linux just works. Face it

P.S. today they are still trying to make his lappy work with that TV screen. No luck yet.

Thought of buying an HTC Vive then I realized I would need to add a few things to my shopping list:
- 16 GB Ram cards
- Windows 10
- 2 TB Hard drive
- NVIDIA Graphics Card
- HDMI Display Port/Controller
- 2 monitors

My parents ended up getting me a Google Cardboard

I was here, before it was wk119...

This is my desk. There are many like it, but this is mine.

The setup is a little dated, but I love it, and when remote working, I've to use the company laptop anyway.

Specs:
Intel Xeon 4x3.3GHz
16gb DDR3
geforce gtx 680
SAMSUNG evo SSD+some HDDs
3 dell ips displays with display port
And my beloved g15 & g700

FFUUUuucccckkk me sideways. So I decided to look into USB type-c's power delivery and alt modes. Cause I kinda want to make an adapter card to run my displays over a single cable. TLDR of the rest: USB-C has some huge capabilities which noone is interested in using since its way to complex to handle for what its worth in the end.
Now PD alone is kinda ok to deal with since a lot of powerbanks use it and some hobby guys documented how to work with it. I find it really odd thou that you NEED to use a dedicated IC for using the configuration chanel to negotiate how much power you can draw. Why the USB standard didnt use some simple 5V low speed signalling? Also the standard says that you only have to implement 5v 0.6A with every other power level being optional. (This is also true for cables. Most manufacturers use only the USB 2.0 standard for them and brag about how fast type-C is. ლ(ಠ益ಠლ) )
Now to the alt modes. These motherfuckers are a real shitshow to deal with. First you need a Mux to deal with USB-C's two way insertion, so your signals wont get flipped. Next thing is that you have four lanes at your disposal in alt mode. Which you can either use for four Display Port Lanes or two DP lanes and two USB 3.0 lanes. (You always get USB 2.0) Now you may think that there would be one simple chip to do it all? Nope you need atleast two at the price of 6$ each. One for PD and one for Alt modes. Both are very hard to solder (QFN, 0.5 mm pitch 40+ pins) TI ended up being the only one with a decent offering of IC's that do what I need. As for working with them, you would think that you just slap a simple MCU on there that communicates over I2C or SPI to configure the chips? Nope! You program the chips memory from which it configures itsself. And the programming is done with some TI tool which gives me no idea as to how you can handle everything whith no control logic behind it.
Looking into alternative IC's leaves me with cypress semi. And their documentation is basically a total mess. I wanna know what that chip is good for and what I need to do to make it work. I dont care about technical details mixed with marketing jargon nobody understands. And I really despise that I have to register just to download a datasheet. Especially since there is no info about it on the main page.
And this whole rant hasnt even touched the topic that USB-C only uses DP and nothing else. So you better hope that you have DP++ so you can use a passive conversion.
This was my Ted Talk about USB-C. Some info in it may be subject to my stupidity and errors as it currently is 02:15 in the morning and I need some sleep.

Desks seem to be a thing, currently. This is my desk. There are many like it, but this is mine.

The setup is a little dated, but I love it, and when remote working, I've to use the company laptop anyway.

Specs:
Intel Xeon 4x3.3GHz
16gb DDR3
geforce gtx 680
SAMSUNG evo SSD+some HDDs
3 dell ips displays with display port
And my beloved g15 & g700

So my MCU teacher said I should use a long ass ternary to determine which pins should be set high for a given number on a seven segment display. Cause the display was on a single 8-bit port on the mcu I decided to generate a bitmask with a switch statement and set the port directly.

So I get to work this morning and find one of my monitors has been moved and my HDMI cable and Display Port adapter are missing...

I've since found the cable, it had made its way onto another desk. When I asked if anyone had seen anything one of the guys said he found an HDMI that's not his on his desk. Still no sign of my adapter though...

So for now I'm back to one monitor like some kind of peasant

New job, new laptop, which happens to be 2k euro MS surface crap.
It comes with win10 S which only allows store apps to be installed, so yeah no making bootable linux for me untill windows drag my ballsack through 2 hours of updating to a pro version.

Wanted to do a nice sweet new debian on it - nope, keyboard not supported in the installation.
I restart...and the fucker completely denied me untill it does another update, which is taking an hour..for now.

And wtf only one usb and mini dp port? In such an expensive laptop?
Cant even plugin my display untill my dock arrives.

Guess I'll have to suck it up and get used to windows for developing for now.

Thx microsoft

Started up KiTTY to connect to my virtual test server per usual when I couldn't establish a connection.

Nothing too unusual so I do the typical troubleshooting I make sure host, port and authentication is all correct and it is. So now I open the display for the virtual server and start looking at ip info, host info, checking ports and everything is completely fine.

Now I'm getting frustrated so I start running things like configtest in apache, using systemctl to check the services status, even restarting virtualbox in my windows 10 devpc. Still cannot connect!

I start feeling hopeless and just shut everything down, the whole operating system.

*takes breath*

Computer boots up and I start my usual thing of creating workspaces, opening editors, starting servers, etc.

I open KiTTY again and launch my virtual test server..

Somethings you just can't fix without a reboot.

FOR FUCK'S SAKE

My verdict on display ports? From 1 to 10 10 being horrible as fuck I'd say it's about the same amount of times my fucking monitor went black and I almost had a siezure.

This may have nothing to do with programming but honestly, it fucking sucks. I've read so much online about how DP is better but no. I've never had a problem with HDMI, but HERE COMES ALONG THE MAGICAL DP. I was playing a FPS game and my left monitor went black over and over and I almost had a siezure. So I umplug the DP cable and my game fucking switches to my right monitor which is portrait mode, AND IT WASN'T EVEN SIDEWAYS GAMING... IT WAS PORTRAIT ON ONE FUCKING MONITOR... PORTRAIT.

I HAD TO PLAY THE REST OF THE GAME LIKE THAT. IN PORTRAIT MODE. THE DOOR FRAMES IN THE GAME WERE SO SKINNY IT LOOKED LIKE PAPER COULDN'T FIT THROUGH IT.

Here, a full retrospective of my Apple products ownership.

iPhone SE – after Android, I was absolutely amazed by how fast it worked. No UI lags, camera works absolutely instantly no matter the light conditions, all the GPU-heavy games work butter smooth.

After camera and charging port failures on Xperia flagship and CPU literally melting through screen rendering it unusable on Meizu, it was enough to make me interested in Apple products.

When I was using Meizu, I actually got a twitching eye which was triggered by UI lags. After two months of using iPhone, I noticed that something was missing – my eye wasn't twitching anymore.

iPhone actually cured me.

MacBook 12 – a 900 grams laptop with passive-cooled mobile CPU running many Chrome tabs, heavy Webpack HMR build, VSCode and Slack just fine. Yes, you can't play games, but I don't even require it from a laptop this tiny.

Butterfly keyboard that internet hates so much actually increased my typing speed and comfort compared to MX Red mechanical keyboard, and ForceTouch trackpad made me forget about mouse. I learned how to disassemble the Butterfly keyboard if I ever need this but the keyboard never failed.

I use this laptop to this day and it still even smells like the day one, a beautiful smell of a new Apple product.

iPhone X – got it because of the camera, stayed for great battery life and amazing OLED display. I use telephoto lens exclusively and it made me lay off my Canon DSLR with Helios lens which stays on my bookshelf covered in dust to this day.

True black of OLED display which is undistinguishable from the screen bezel is stunning. To this day, battery surely works for one and a half days and I watch youtube really often.

I sometimes struggled to unlock iPhone SE with wet fingers, but with FaceID, as soon as I look at the screen the phone is unlocked. Works perfect every time, never had an issue with this.

Stainless steel body feels premium compared to aluminum. Stereo sound is a major selling point if you're like watching videos and playing games on your phone. Overall amazing product and a huge improvement over SE.

Apple Watch series 4 – really comfortable fit. Nice battery life, once I forgot about it for like ten days during lockdown and it was still working, even though on power reserve mode. Really reliable in terms of battery life and liquid protection. Very satisfying Taptic Engine crown clicks. I run every day and Apple watch always measure my heart rate correctly, and the running app is well designed and a pleasure to use. Overall a nice accessory to have if you use iPhone.

Powerbeats Pro – great sound and battery life. I switched from Shure SE215 which was great, but it had wires. I listen to a lot of music so the sound quality is important for me. When I was choosing earphones I visited a store where you can listen to them all. I listened through earphones like Noble Audio Kaiser Encore and JH Audio Layla, and of course $4000 Laylas sound better than $249 bluetooth earphones, but the difference in sound doesn't justify the difference in price to me.

Powerbeats pro is the Apple H1 chip true wireless earphones with largest driver of them all which makes them sound better than AirPods Pro – it's just physics. Bass in Powerbeats is amazing, which is also true for my Shures, but Powerbeats also win in clarity.

It connects seamlessly to both my MacBook and my iPhone, and everyone in voice chats can hear me really good.

Huge case is a major throwback compared to AirPods, but the battery life of earphones themselves is so great that I just leave the case at home and only carry earphones and it works for me.

Apple Link bracelet in space black – really better than I expected. Intricate detailing, literally the steel that Rolex uses, top-notch finishing and polishing – all that for just 450 dollars. I only used it for several days now, but it already feels like a really satisfying product.

Before all that I was using Linux. It took a year for elementaryos devs to fix wifi for my laptop. Ubuntu looks and feels ugly. Pop OS felt like garbage. Manjaro was also just that – garbage. KDE Plasma – I don't even want to talk about that. A monstrocity where you accidentally click a wrong switch in the settings and your system won't boot up again. Also, PulseAudio. Struggles with proprietary drivers and software updates.

Windows? I serviced a lot of Windows PCs through my career and it never, never worked as intended. I'm no dumbass, I always managed the rights correctly and never installed sketchy apps. My latest ryzen gaming build with a lot of ram also lags somehow even in Windows 10 UI.

Before I switched, I defended Linux.

My life was a lie.

I'm sorry to everyone who I offended based on their opinion on Linux.

The contractor/developer sitting next to me asked for a power adapter for the MacBook the company issued him (it's an older MacBook that currently connects to his monitor with one of those 2-in-1 power and display port cables).

They told him it was not company policy to provide power adapters to contractors.

They also wouldn't give him a license for a Windows VM for some Windows specific stuff he needed to work on for an outside vendor, stating it was a "security risk"

They've also talked about taking Linux off my laptop (which I run natively outside a VM cause fuck MacOS).

I hate our IT department. They're the least competent and least helpful bunch I've ever met.

Windows is so fucking stupid. Why do I HAVE to enable "Do nothing" when my lid is closed for it to be able to output to my external display while my lid is closed. Ubuntu can easily recognise that I want to use my external display and will keep my laptop running as long as it has an HDMI to a connected source.

It really fucking pisses me off I have to change my power options everyday. Seriously fuck windows. The only thing keeping me on Windows is Visual Studio, I hope they are able to port VS and the full .NET framework entirely on Linux so this shit OS can just be dead forever.

I'm running a 4K monitor on my ThinkPad T470P with Display Port. I'm getting quite a bit of latency/lag. Anyone happen to know why?

Can anyone help me with this theory about microprocessor, cpu and computers in general?

( I used to love programming when during school days when it was just basic searching/sorting and oop. Even in college , when it advanced to language details , compilers and data structures, i was fine. But subjects like coa and microprocessors, which kind of explains the working of hardware behind the brain that is a computer is so difficult to understand for me 😭😭😭)

How a computer works? All i knew was that when a bulb gets connected to a battery via wires, some metal inside it starts glowing and we see light. No magics involved till now.

Then came the von Neumann architecture which says a computer consists of 4 things : i/o devices, system bus ,memory and cpu. I/0 and memory interact with system bus, which is controlled by cpu . Thus cpu controls everything and that's how computer works.

Wait, what?
Let's take an easy example of calc. i pressed 1+2= on keyboard, it showed me '1+2=' and then '3'. How the hell that hapenned ?

Then some video told me this : every key in your keyboard is connected to a multiplexer which gives a special "code" to the processer regarding the key press.
The "control unit" of cpu commands the ram to store every character until '=' is pressed (which is a kind of interrupt telling the cpu to start processing) . RAM is simply a bunch of storage circuits (which can store some 1s) along with another bunch of circuits which can retrieve these data.

Up till now, the control unit knows that memory has (for eg):
Value 1 stored as 0001 at some address 34A
Value + stored as 11001101 at some address 34B
Value 2 stored as 0010 at some Address 23B

On recieving code for '=' press, the "control unit" commands the "alu" unit of cpu to fectch data from memory , understand it and calculate the result(i e the "fetch, decode and execute" cycle)

Alu fetches the "codes" from the memory, which translates to ADD 34A,23B i.e add the data stored at addresses 34a , 23b. The alu retrieves values present at given addresses, passes them through its adder circuit and puts the result at some new address 21H.

The control unit then fetches this result from new address and via, system busses, sends this new value to display's memory loaded at some memory port 4044.
The display picks it up and instantly shows it.

My problems:
1. Is this all correct? Does this only happens?

2. Please expand this more.
How is this system bus, alu, cpu , working?
What are the registers, accumulators , flip flops in the memory?
What are the machine cycles?
What are instructions cycles , opcodes, instruction codes ?
Where does assembly language comes in?
How does cpu manipulates memory?
This data bus , control bus, what are they?
I have come across so many weird words i dont understand dma, interrupts , memory mapped i/o devices, etc. Somebody please explain.

Ps : am learning about the fucking 8085 microprocessor in class and i can't even relate to basic computer architecture. I had flunked the coa paper which i now realise why, coz its so confusing. :'''(

Do we have vfio enthusiasts here?

Now that I made my second GPU boot into Arch Linux (inb4 I use arch, btw. jokes in the comments), I also set up a windows vm with GPU passthrough.

When I plug the monitor cable into the hdmi port of my passthrough'd GPU, I can see windows os on the screen.

My problem is that I want to have it inside of the same monitor without changing the from hdmi port to hdmi port manually, but "softwarely" (neologism ftw).

I read about looking-glass in the arch wiki (I use arch, btw. + On a serious side note though, I really like the arch wiki. It is very straightforward.), but I could not get it to synchronize with the Spice display server.

Does someone know how the solution to this problem?

Why the heck can't a Dell display (or even better a daisy chain of them) be connected through a Dell docking station to a Dell laptop via Display Port? Seems like they should be compatible after all.

I'm fucking tired of my computer having random
2 seconds latency on any basic action and being slow as fuck regardless of powerful processor, ssd and 32GB RAM. Music via bluetooth is basically unusable since every few seconds the music stops for a 0.2s then plays again. I installed this system (opensuse tumbleweed) in February this year and it's just sad that I have reinstall again (any ideas for distro) ?

I made a dummy mistake of buying a CPU without internal graphics and this resulted in having to buy a GPU. So I got myself Nvidia(another mistake) since i though i would be using CUDA on the university. Turnes out CUDA cannot be installed for some retarded reason.
With Nvidia GPU the screens on my two monitors are swapping every time I use a hdmi switch to use other computer. On AMD GPU this problem does not exist. AMD GPU pro drivers are impossible to install. Computers barely fucking work, change my mind. Shit is breaking all the time. Everything is so half assed.

The music player that i use sometimes swaps ui with whatever was below it like for example the desktop background and i need to kill the process and start again to use the program. WTF.

Bluetooth seems to hate me. I check the bluetooth connected devices on my computer, it says headphones connected. BULLSHIT. The headphones are fucking turned OFF. How the fuck can they be connected you dumbass motherfucker computer. So I turn on the headphones. And I cannot connect them since the system thinks that they are already connected. So I have to unpair them and pair them again. WTF. Who fucking invents this bullshit?
Let's say i have headphones connected to the computer. I want to connect them to phone. I click connect from the phone settings. Nothing happens. Bullshit non telling error "could not connect". So I have to unpair from computer to pair to phone. Which takes fucking minutes, because reasons. VERY fucking convenient technology.
The stupid bluetooth headphones have a loud EARRAPE voice when turning them on "POWER ON!!! PAIRING", "CONNECTED", "DISCONNECT". Loudness of this cannot be modified. The 3 navigation buttons are fucking unrecognizable so i always take few seconds to make sure i click the correct button.

Fucking keyboard sometimes forgets that I remapped esc key to caps lock and then both keys don't work so i need to reconnect the keyboard cable. At least it's not fucking bluetooth.

The only reason why hdmi switches exist is because monitor's navigation menus have terrible ui and/or infrared activated, non-mechanical buttons.
Imagine the world where monitors have a button for each of it's inputs. I click hdmi button it switches it's input to hdmi. I click display port button - it switches to display port. But nooo, you have to go through the OSD menu.

My ~ directory has hundred of files that I never put there. Doesn't feel like home, more like a crackhead crib.

My other laptop (also tumbleweed) I click on hibernate option and it shuts down. WTF. Or sometimes I open the lid and screen is black and when i click keyboard nothing happens so i have to hold power button and restart.

We've been having computers for 20 + years and they still are slow, unreliable and barely working.

Is there a cure? I'm starting to think the reason why everything is working so shitty and unreliable, is because the foundations are rotten. The systems that we use are built with c, ridden with cryptic abbreviated code, undefined behavior and security vulnerabilities. The more I've written c programs the more convinced I am, that we should have abandoned it for something better long ago. Why haven't we? And honestly what would be better? Everything fucking sucks. The rust seems to be light in the tunnel but I don't know if this is only hype or is it really better. I'm sure it can't be worse than c or c++. Either we do something with the foundations or we're doomed.

Can anyone recommend a docking station with multiple hdmi and/or display port ports für Linux laptops?
