As an Australian, I find the fact that I need 750++ just to let my avatar wear thongs is oppressing my heritage and is extremely racist. #triggered8

One of our senior dev enjoys berating the other devs because they don't check-in code according to his schedule (once a day, once an hour..he flip-flops a lot), then when they do, he 'reviews' their code, beating them up because of incomplete features, commented out code..petty..petty nonsense.
Ex. (this occurred couple of weeks ago).
Ralph: "The button click code in this event isn't complete"
Dev: "No, its not, the code in my development branch. You said it was best practice to check in code daily whether the code worked or not. I didn't finish the event last night and ..."
Ralph: "Exactly. Before you check any code into source control, it has to work and be 100% complete. What if someone moved that code into production? What happens if that code got deployed? I'm not even going talk about the lack of unit tests."
Dev: "Uh..well..the code is on the development channel, and I branched the project in my folder ...I didn't think it mattered.."
Ralph: "Ha ha...you see what happens when you don't think...listen..."
- blah blah blah for 10 minutes of hyperbole nonsense of source control check-in 'best practice'
This morning Ralph's computer's hard-drive crashed.
Ralph: "F-k! ..F-k! ... my f-king computer hard drive crashed!"
Me: "Ouch...did you loose anything important?"
Ralph: "A f-king week of code changes."
Me: "You checked everything into source control on Friday ...didn't you?"
Ralph: "F-k no!...I got busy...and...f-k!"
Me: "Look at the bright side, you'll have a good story to tell about the importance of daily check-ins"
Oh...if looks could kill. Karma...you're the best. -
Alright, biiiiig rant time.
Shitty webdevs who randomly use an entire framework for some tiny feature in the middle of their codebase because they couldn't figure out how to do it with native and completely fucking up their syntax, consistency and standards set beforehand (not that there were any to begin with, this dude program's like 3-4 people just jumbled all their crap into one massive pile).
Not only that but throughout the entire backend this guy flip-flops on passing an the error value before results in his callbacks, so now i have to check his functions everytime I use them after spending 2-3 sessions debugging to figure out wtf was going wrong.
Please for the love of god, if you wanna dance to your own beat, LEAVE COMMENTS4 -
Hey, fellow dRs.
I may need some help regarding this circuit.
It is about an 8 Bit multifunctional shift register with a 2 Bit instruction set.
These work:
If "Sel" is 0x00, the circuit loads data into its 8 D flip flops.
If "Sel" is 0x03, the circuit replaces all data with 0s.
These don't work (they do, but they do it in a very strange way and end up filling 1s instead):
If "Sel" is 0x01, it is supposed to ringshift bitwise to the right.
If "Sel" is 0x02, it is supposed to ringshift to the left.
As mentioned above. They do it in a very strange way. If we have 10000000, it will shift to the left or right depending on the "Sel"'s binary value. Let us say we want to shift it right. The output will turn from 10000000 to 01000000 (which is what we want), BUT after that it adds another 1 to it: 01100000. It keeps doing it until every single Bit is a 1. Same thing happens with the left ringshift.
I will include the other circuits used in this circuit in the comment section.25 -
I understand we are devs and allowed to wear what we want to a certain extent, but why must people wear flip flops. I don’t want to see/smell your feet for 8 hours20

My collaborator was always telling me what a great team we are, until it got serious.
Getting stabbed back in the butt and fired from your job. HAHA what great Teamwork...
After that steal all my ideas and projects and sell them as there own.
I hope that guys Flip-Flops will burn someday1 -

Lets you place clocks, full and half adders, D latches, RS and JK flip-flops, shift registers, demultiplexers, multiplexers, and decoders, as well as all the standard gates. It also has buttons, switches, and individual LEDs.
Pretty close to what I would make myself.6 -
i am i such a shitty situation. i have recently started to love my job as i find the work to be lesser and lesser stressful. i finish my tickets in 2-3 hours exch day, and i am almost free after 3 pm and officially free after 6.30 pm every day (kinda officially, as i have set an unavailable notice on my calendar for 6.30 to 8.30 and after that no one really is online).
i get time to go out, jog, play with my pets do home taks, and even study sometime.
everything is going great except 2 things: they are ending the remote work policy in 2022 and giving esops instead of appraisal/promotion :'( will have to either switch or go live in the city where my office is, which is the most expensive city in my country ( and maybe in top 10 most expensive in the world) + very unsafe. and its obvious that my boss won't be letting me code lying flat on a mattress with a bag of cheetos and in just boxers and flip-flops2 -
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. :'''(14 -
So i was just reading about some electronics..and just realised computers were possible only because one crooked mind thought what would happen if i give the output of a gate to itself ?
I know there may be some explanations.. But flip flops are memory right ?4 -
Bruh, just learn them how a computer works with minecraft. Inverters, And, Nand, etc... can all b made there. From there, u can make flip-flops, u can make registers, adders, multiplexors, demuxs. Ofc makin anything more then a 1-bit, maybe 2-bit machine, would be a pain, and dont get me starting on memory that extends one register. But hey, if u got the patience, u can ofc. Put it together to an ALU, combin all of them with a PC to an CPU. Ofc, you got no ROM or RAM, but hey, atleast u've built the hard part.4
