1 minute of Thread.sleep() for Tum, the best cat ever. Rest in peace, your memory will live on in my devrant avatar.

Account guy saw me coding...

account guy: so you type a lot.. how can you remember so much??

me: ??

account guy: I mean there is NO LOGIC in what you do, so you must read these things and type them here... you need to remember a lot.. right??

me: ohh... that... well.. I have very good memory :)

p.s. last line was sarcasm

New guy: There's a memory leak in my code.
Me: You need to free the memory you previously allocated.
New guy: Already did that, deleted everything from my "Downloads" folder and some stuff from my Desktop.
Me: *Long Pause* Have you tried "rm -rf /" yet ?

This post is in memory of all the devRanters fallen in battle against management stress and impossible deadlines.

Let their memories remain, and their loss never be forgotten.

I finally built a new PC with 8GB memory, i7 4790K and SSD for OS.

My old system was a core2duo with 2GB memory. Android studio used to take 20mins for gradle sync and another 20min for signing apks. "Live preview" and "emulator" was a thing of the future for me. Never used it.

But now things have changed. This thing boots up in less than 5 sec and studio gradle takes less than 30sec. I'm so happy right now! Its like a dream come true! *cries in happiness*

When I was in 7th grade, my neighbor (a DoD programmer) challenged me to write a sorting algorithm for a hypothetical super limited environment (he said a satellite). It didn’t have any built-in sorting methods, had very limited memory, slow processor, etc. so I needed to be clever about it.

It took me a few nights before i found a solution he liked. The method I came up with counted the number of occurrences of each number in the array and put them in the appropriate spots in a new array. This way it only required O(2n) running time and 2n memory.

I just learned today that this is called the “counting sort” 😄

I’m proud of little 11 year old me.

Me: you should not open that log file in excel its almost 700mb
Client: its okay, my computer has 4gb ram
Me: *looking at clients computer crashing*
Client: the file is broken!
Me: no, you just need to use a more memory efficient tool, like R, SAS, python, C#, or like anything else!

Me: Visual Studio 2019 is acting weird. I should close it and re-open.

Me: *Clicks X in top right of instance window*

Dialog: Not enough memory to perform this operation.

After 2 hours of wiring/debugging/rewiring, I have my EEPROM programmer halfway done. Currently is only able to read locations in memory. Next step: make it programmable.

(For those of you who dont know, EEPROM stands for Electrically Erasable, Programmable Read-Only Memory

Working with memory in C

Google: “Your websites must load the first byte in under 500ms and be fully loaded with no render blocking and local caching of all external site callouts to even begin to rank in Google searches.”

The time my Java EE technology stack disappointed me most was when I noticed some embarrassing OutOfMemoryError in the log of a server which was already in production. When I analyzed the garbage collector logs I got really scared seeing the heap usage was constantly increasing. After some days of debugging I discovered that the terrible memory leak was caused by a bug inside one of the Java EE core libraries (Jersey Client), while parsing a stupid XML response. The library was shipped with the application server, so it couldn't be replaced (unless installing a different server). I rewrote my code using the Restlet Client API and the memory leak disapperead. What a terrible week!

When you create a bunch of objects in Java and it crashes because you're used to the memory usage of C's structs.

Talk about naming your classes aptly.

Teacher: Computer settings are stored in the ROM on the motherboard.
Me: *internally* Uhm, yea, sure... and I am the pope
Me: Sorry to interrupt you but how come the BIOS settings get reset when the CMOS battery is pulled out or dies if they are stored in ROM?
Teacher: ....
Me: *internally* yea, that's what I thought, you have no clue what you are even saying - the BIOS is stored in ROM or flash memory while the settings are stored in NVRAM also called CMOS memory...

I have just concluded a post-mortem on one of my servers.
Cause of death: out of memory due to a tiny memory leak in a VPN service triggered by 66 different IPs brute-forcing the creds at the same time. Mostly from China, of course.

Dear bot writers: you made me put aside my spaghetti and write iptables rules. I hate iptables. And I love spaghetti. You should be ashamed of yourself! Did momma not teach you basic OpSec? Don't crash the target and never, ever, interrupt the sysadmin during dinner!

Application has had a suspected memory leak for years. Tech team got developers THE EXACT CODE that caused it. Few months of testing go by, telling us they're resolving their memory leak problem (finally).

Today: yeah, we still need restarts because we don't know if this new deployment will fix our memory leak, we don't know what the problem is.

WHAT THE FUCK WERE YOU DOING IN THE LOWER REGIONS FOR THREE FUCKING MONTHS?!?!?! HAVING A FUCKING ORGY???????????????

My friends took the time to find your damn problem for you AND YOU'RE GOING TO TELL ME YOU DON'T KNOW WHAT THE PROBLEM IS???

It was in lower regions for 3 MONTHS and you don't know how it's impacting memory usage?!?!?! DO YOU WANT TO STILL HAVE A JOB? BECAUSE IF NOT, I CAN TAKE CARE OF THAT FOR YOU. YOU DON'T DESERVE YOUR FUCKING JOB IF YOU CAN'T FUCKING FIX THIS.

Every time your app crashes, even though I don't need to get your highest level boss on anymore for approval to restart your server, I'M GOING TO FUCKING CALL HIM AND MAKE HIM SEE THAT YOU'RE A FUCKING IDIOT. Eventually, he'll get so annoyed with me, your shit will be fixed. AND I WON'T HAVE TO DEAL WITH YOUR USELESS ASS ANYMORE.

(Rant directed at project manager more than dev. Don't know which is to blame, so blaming PM)

When you introduce your girlfriend to your Best friend and after some time they start dating each other and you are unaware of the situation but after sometime you get to know about their relationship , now you're really pissed and want to take revenge, then you remember that the girl's parents are strict af and you know that they won't tolerate that their daughter is in relationship
so, you tell her parents about her and
they decide to send her to a different school located in another city
The End

tl;dr
When two pointers are pointing to a same memory location then if any one of them deallocates the memory, the other pointer becomes a dangling pointer

Storytime
A story about an Android TVbox which decided to become an iPad

Several years ago we've bought an android tv-box. 

It served me and my family well for several years.

Specs are not that important in this story, but there they are:

Android 4.4 
1GB RAM
Amlogic quadcore 1.4HGz
8GB memory.

This device served us well - online TV, browsing, music, file sharing and so on. But recently cheap Chinese memory deciteed to take a break and damaged ROM. Because of that device won't boot. The only option was to take it apart and "short circuit" certain legs on memory chip and make it boot from SD card and install new firmware. After such operations tv-box worked well again. 

Hoverer, memory glitched again and again and this algorithm was repeated for several months.

But that is not what is this story about.

One day memory went completely crazy and there was no way to install new firmware on it. It just hanged on install. (BTW, it was official firmware for this device)

But after countless attempts it finally worked! It installed the firmware and booted into launcher and connected to WiFi! 

But now comes the most interesting part. 

It was not android anymore.

It decided to became an iPad.

My dad logged in to his Google account via tv-box and got mail that someboby connected from our IP via iPad (we don't have an iPad) and using safari browser! Stock browser is not safari browser.....

"Ok, nvm, crazy glitch." - we thought.

But preinstalled play marked wont launch. Because he told us, that we're trying to connect from iPad.

And Google chrome page suggested to download chrome for iPad

And everything was acting like it is an iPad.

OK, downloaded iTunes, why not??? ._.

Tried to install elixir for android via apk from flash, but then memory glitched one more time, everything went black and tv-box had damaged ROM again...

After that we decided to not torment it anymore...

That's it. Poor Android TVbox that all his life dreamed to become an iPad. Rest in peace.

Wonder if I'll ever feel like a real programmer in web dev surrounded with C++ gurus that eat, sleep, and breathe memory allocation and optimization algorithms. I'm just over here like... You can go to this link and a pretty red box moves around on the screen

I can't name one specific time that was the best memory per say. My team is super close - we get lunch almost every day, have (inappropriate) inside jokes and just act dumb together. Not one person on my team who doesn't fit in. Even our boss is cool. :) #LoveMyTeam

its 2016, and they still believe that office skillz are enough for CS101..

boy u have to allocate memory in runtime without leaks by end of semester, not just make a text bold with a fancy font..

I like memory hungry desktop applications.

I do not like sluggish desktop applications.

Allow me to explain (although, this may already be obvious to quite a few of you)

Memory usage is stigmatized quite a lot today, and for good reason. Not only is it an indication of poor optimization, but not too many years ago, memory was a much more scarce resource.

And something that started as a joke in that era is true in this era: free memory is wasted memory. You may argue, correctly, that free memory is not wasted; it is reserved for future potential tasks. However, if you have 16GB of free memory and don't have any plans to begin rendering a 3D animation anytime soon, that memory is wasted.

Linux understands this. Linux actually has three States for memory to be in: used, free, and available. Used and free memory are the usual. However, Linux automatically caches files that you use and places them in ram as "available" memory. Available memory can be used at any time by programs, simply dumping out whatever was previously occupying the memory.

And as you well know, ram is much faster than even an SSD. Programs which are memory heavy COULD (< important) be holding things in memory rather than having them sit on the HDD, waiting to be slowly retrieved. I much rather a web browser take up 4 GB of RAM than sit around waiting for it to read the caches image off my had drive.

Now, allow me to reiterate: unoptimized programs still piss me off. There's no need for that electron-based webcam image capture app to take three gigs of memory upon launch. But I love it when programs use the hardware I spent money on to run smoother.

Don't hate a program simply because it's at the top of task manager.

Him: Relation databases are stupid; SQL injections, complex relationships, redundant syntax and so much more!

Me: so what should we use instead? Mongo, redis, some other fancy new db?

Him: no, I have this class in Java, it loads all the data into memory and handles transfers with http.

Me: ...... Bye!

Remember guys, when naming your firstborn child you can cause a stack overflow in the system’s memory by naming it %5E2019F% allowing you to sideload unsigned external code and run DOOM

Overheard guy on the bus: "...but I don't understand where variables go in memory."

It took 100% of my will power to not pop over the seat like some muppet to sing song about stacks and heaps.

There is only one important rule to live by:

Never lend anyone your 256 GB USB-C/USB-B combo memory stick. There is a 100% scientifically-backed certainty that you will never, in your meager existence, see it again.

You haven't actually *begun* to learn anything until you've shouted FUCK THIS SHIT (or some variation) out loud at least once.

The anger is what makes it stick in your memory.

Woohoo! I fixed a huge memory leak in our app! ... In one class.

Time for noise cancelling head phones, 80s hacker music, tons of caffeine, and more leak hunting. :)

I hate it when you CTRL-Z half way, try to fix the problem from that point and realise you fucked up. Try CTRL-Zing more and realise you fucked up your chances to get to the point you wanted :). Every single time.

It is with a heavy heart that I said aufwiedersehen to my mom last night. She passed peacefully in her sleep, and is now resting in the fields and forests of heaven. She was born in 1932 in Hamburg, Germany, and at age 7 the world around her exploded into one of the most horrific wars that Europe or the world had seen up to that time. By the time it was over, she was thirteen, and had spent many of her formative years witnessing how low humanity can get in the treatement of fellow humans. She survived the post-war years, and came to the US in the late 1950's, and met my dad while in nursing school. She had four chidren, Tim, Chris, Tanya, and myself. She was a doting and caring mom, who dedicated herself to raising her children. She loved to cook, loved animals, especially dogs, and love human beings in general, and had a compassionate and kind heart. There is a small, empty space in the world that she filled, but heaven is a little brighter with her smile and her laughter. I miss you mom, but I know I will see you again some day. Aufwiedersehen, lieber Mutti! Wir sehen uns bald.

That, my friends, is a Dell Poweredge r610, with 2x e5670 and 48GB of registered ECC memory, mounted underneath my desk at work, using mounts I 3D printed at home.

Roughly £140 all in, and I now have a nice little development server, AND leg heater!

Ooof.

In a meeting with my client today, about issues with their staging and production environments.

They pull in the lead dev working on the project. He's a 🤡 who freelanced for my previous company where I was CTO.

I fired him for being plain bad.

Today he doesn't recognize me and proceeds to patronize me in server administration...

The same 🤡 that checks production secrets into git, builds projects directly in the production vm.

Buckle up... Deploys *both* staging and production to the *same* vm...

Doesn't even assign a static IP to the VM and is puzzled when its IP has changed after a relaunch...

Stores long term aws credentials instead of using instance roles.

Claims there are "memory leaks", in a js project. (There may be memory misuse by project or its dependencies, an actual memory leak in v8 that somehow only he finds...? Don't think so.)

Didn't even set up pm2 in systemd so his services didn't even relaunch after a reboot...

You know, I'm keeping my mouth shut and make the clown work all weekend to fix his own hubris.

The top reasons to become a dev are:
- your brain acutally gets challenged to its fullest
- you can fix most of your IT problems yourself
- you are forced to learn how to deal and live with stress

I won't list the disadvantages, becaus it would result in memory allocation errors.

That moment when you thought you've fortified yourself with enough RAM for the future (32GB) and Blender fails to work with a large project because...it runs out of memory (just in the loading phase, building them intermediate data structures pushes it over the edge I guess).

Fml.

It was kind of fascinating to watch the memory usage indicator creep up though. Morbid fascination.

So today I saw this guy:

long size = long.MaxValue;
//method that may or may not set
//size

int[] array = new int[size];

Apparently we are processing blu-ray movies in place in memory.

Programmers then:

No problem NASA mate, we can use these microcontrollers to bring men to the moon no problem!

Programmers now:

Help Stack Overflow, my program is kill.. isn't 90GB (looking at you Evolution) and 400GB of virtual memory (looking at you Gitea) for my app completely normal? I thought that unused memory was wasted memory!1!

(400GB in physical memory is something you only find in the most high-end servers btw)

Writing an emulator for an 8-bit computer with 8-bit memory addressing in C. Or maybe writing a web server in C... Both were really fun and I learned a lot. (But I love C, so there’s that)

An overflow in C, the program was writing 16 Bytes in an array of length 10 due to some mistake.
The problem was this ended up overwriting another place in the memory that was used by another algorithm to perform calculations... So we thought that the algorithm was buggy all along.

In memory of the giant of engineering that was Larry Tesler, today I will be coding solely by copying and pasting. Thanks for making my life so easy, Larry. RIP.

A huge amount of memory leakage in a C++ project which was from a mistaken 'new' statement which was not deleted

Life Before the Computer

An application was for employment
A program was a TV show
A cursor used profanity
A keyboard was a piano!

Memory was something that you lost with age
A CD was a bank account
And if you had a 3-inch floppy
You hoped nobody found out!

Compress was something you did to garbage
Not something you did to a file
And if you unzipped anything in public
You'd be in jail for awhile!

Log on was adding wood to a fire
Hard drive was a long trip on the road
A mouse pad was where a mouse lived
And a backup happened to your commode!

Cut - you did with a pocket knife
Paste you did with glue
A web was a spider's home
And a virus was the flu!

I guess I'll stick to my pad and paper
And the memory in my head
I hear nobody's been killed in a computer crash
But when it happens they wish they were dead!

Dear customer,
You pointed out, that the program is failing due to insuffizient memory.
"Memory" is the RAM in your Laptop.
"Insuffizient" means YOUR FUCKING RAM CANT HOLD THE ENTIRE 2 TB DATABASE!

GTFO and RTFM!

Best regards
me

Our team makes a software in Java and because of technical reasons we require 1GB of memory for the JVM (with the Xmx switch).
If you don't have enough free memory the app without any sign just exits because the JVM just couldn't bite big enough from the memory.
Many days later and you just stand there without a clue as to why the launcher does nothing.
Then you remember this constraint and start to close every memory heavy app you can think of. (I'm looking at you Chrome) No matter how important those spreadsheets or illustrator files. Congratulation you just freed up 4GB of memory, things should work now! WRONG!
But why you might ask. You see we are using 32-bit version of java because someone in upper management decided that it should run on any machine (even if we only test it on win 7 and high sierra) and 32 is smaller than 64 so it must be downwards compatible! we should use it! Yes, in 2019 we use 32-bit java because some lunatic might want to run our software on a Windows XP 32-bit OS. But why is this so much of a problem?
Well.. the 32-bit version of Java requires CONTIGUOUS FREE SPACE IN MEMORY TO EVEN START... AND WE ARE REQUESTING ONE GIGABYTE!!
So you can shove your swap and closed applications up your ass but I bet you that you won't get 1GB contiguous memory that way!
Now there will be a meeting about this issue and another related to the issues with 32-bit JVM tomorrow. The only problem is that this issue only occures if you used up most of your memory and then try to open our software. So upper management will probably deem this issue minor and won't allow us to upgrade to 64-bit... in 20fucking19

Our team is currently working with an Excel document that uses visual basic to talk to an embedded system. We're talking reading memory locations in Excel.

Our junior programmer is stuck in a do-while loop. He starts with a normal question, and then each question after will be "But Why ?", until I am ready to throttle him, or I run out of memory.

Boasting you know programming just because you watched some programming videos doesn't help in any of the case, I learned this the hard way because I tried to show off in front a girl and turned out, she knew more and better. This was when I was 14, very bad memory

I've got a file on my desktop called key.txt, and it's just a single line in it that is clearly some sort of API key.

Absolutely no memory of what it is for.

💩

So working on the Android for work, and go to add in images for parts of the app. I add in images and load the app up and it crashes, I thought hmm maybe I missed something for the imageview.

The exception was an out of memory exception and from looks of it, it exceeded my phone memory by quite a bit (OnePlus 3 has 8gb LOL), I was stumped since I don't typically run into this.

Turns out this time around it wasn't my fault lol, I had some images outsourced to a company our company uses for doing design work and well Android doesn't like 2000 x 2000 super high quality for logos.

I mean sure it's good it's high quality but to have 3 images eat up a lot of memory (I assume my phone won't allocate all 8gb to one app lol).

- Let's write some code to check for memory leaks
- Oh shit, memory is leaking like crazy
- In fact the program crashes within 10 minutes
*Some hours of debugging and not finding the cause later*
- Starts thinking about the worse
- Hell yeah, the memory leak is caused by the code that checks for memory leaks. But fucking how
- Finds out the leak is caused by the implementation of the std C lib
- In the fucking printf() function
- Proceeds to cry

A graphical artist wanted to save memory by coloring unused pixels in a spritesheet black because 0 is less than 255...

My new motherboard (MSI Z170 GAMING AC) reports temps for the memory, CPU, GPU and hard drive in °C. And the motherboard temp in °F.
Almost had a fucking heart attack the first time I opened Speccy for benchmarking.

Reading up on how floats are stored and it's pretty cool how you can store numbers as large as 3.4×10^38 in the same amount of memory that an integer can store only about 2 billion.

Absolutely wonderful

Approximately 15 years ago, at school, I had one friend that learned to code in Delphi. One day he came to me and said:
Dude! I made a program that creates a 2GB file!!! (15 years ago 2GB were a lot of memory)
- What is in this file? - I asked.
- Nothing! It's just 2GB!!!
- It's fucking AWESOME!!!

God damn it lastpass, how the hell do you get a memory leak and an infinite loop in a fucking browser extension?! Using 7GB of RAM and all 8 cores @ 3,4GHz!!

God: you qualify for reincarnation. What advice from past life do you want me to retain in your memory ?
Me: never forget to write those unit tests!

Today I tried medication (concerta 36mg) for my ADD for the first time in my life (im 26 years old).

Result is fuck yeah! I feel like a human being whos able to focus on shit. Im so jealous of normal people having a decent attention span and decent working memory.

So, CS student here.
Gave TCS "national" level test.
Quoting from the question:
"if you have 3 bytes of memory, it can be used to represent 2^3=8 values in the memory"

This test is a waste of at least 30000+ human hours and these guys didn't even put 24 hours of effort to make sure questions are correct.
Fuck this fucking IT industry.
Fuck the people who designed this testing process.
Fuck the people who endorsed this process.
Fuck the management for passing it as a test.
The people who wrote the test question can go die in hell.
It's not my problem that their mothers fucked Neanderthals.

Uh! All I want is a job but ended up wasting 200+ hours of time.

For the first time in my life windows 10 repair fixed the PC?

Was getting bluscreen regarding unmountable boot, memory management then try to open it now it started diagnosing your PC.
Started reading devrant it fixed the problem and it works now.

We all know you can't "learn x programming language in a day" without travelling to the Arctic and catching a day that last half a year.

But what's the worst language to try and learn in a day?

I vote c++. Manual memory management, multiple inheritance, static compilation, operator overloading, and generally non-human syntax ( Like std::cout << "This is how you print!" << std::endl; ) make it a difficult one to attempt in a day.

Q: What's a "muscle memory"?

A: It's when you open up devRant, skim through several posts, get bored, decide to visit some other website for more stimulation, close the tab with devRant, open a new tab and your hands type in devrant.com [ENTER] before you know it

Hey girl are you a variable? Because you're stuck in my memory!

Silently rebooting device every night cause of memory leaks in CEF.

I find it funny on Windows, Android studio reaches as much as 12GB of ram usage, while on Linux two instances barely take up to 3GB

Either java sucks on Windows or AS sucks in memory usage but happened to be saved by Linux

Apple really needs to add a "Deceased" tag to its facial recognition system, I just had a "memory" appear with a full 1:30 minute long video of my Grandmother who passed away earlier this year with "extreme" music in the background

When the hero turns into villain.

Windows memory management is one of the worst architectural designs in tech industry to ever exist.

One mistake on my part is I did not opt for SSD four years ago when my purchased my current laptop.

The entire experience is irritating.

Lesson learned: if you're going to derive a class in c++, make sure to declare a virtual destructor on the base class!

I just fixed (one of...) the massive memory leaks in my damn project.

Pictured: the strings in a derived class actually getting freed!

Anybody else have a wall like this in their workspace or is it just me? I've got bad memory for config strings haha!

My first contact with an actual computer was the Sinclair ZX80, a monster with 512 bytes of ram (as in 1/2 kbyte)

It had no storage so you had to enter every program every time and it was programmed in basic using key combinations, you could not just write the commands since it did not have memory enough to keep the full text in memory.

So you pressed the cmd key along with one of the letter keys and possibly shift to enter a command, like cmd+p for print and it stored s byte code.

Problems with redis... timeout everywhere...

30k READs per minute.

Me : Ok, How much ram are we actually using in redis ?

Metrics : Average : 30 MB

Me ; 30 MB, sure ? not 30 GB ?

Metrics : Nop, 30 MB

Me : fuck you redis then, hey memory cache, are you there ?

Memory cache : Yep, but only for one instance.

Me ok. So from now on you Memory cache is used, and you redis, you just publish messages when key should be delete. Works for you two ?

Memeory cache and redis : Yep, but nothing out of box exists

Me : Fine... I'll code it my selkf witj blackjack and hookers.

Redis : Why do I exist ?

An undetectable ML-based aimbot that visually recognizes enemies and your crosshairs in images copied from the GPU head, and produces emulated mouse movements on the OS-level to aim for you.

Undetectable because it uses the same api to retrieve images as gameplay streaming software, whereas almost all existing aimbots must somehow directly access the memory of the running game.

Memory just came up from reading another rant about static keyword I wanted to share. Involved a network programming assignment in Java back in my heyday.

Fellow student was told that a static member was shared between every object in a class and decided that they could use that to implement network communication (i.e. if they ran the same java program on different machines, they'd be able to communicate by reading to and writing from the same static fields).

Have a memory of sitting in corner of lab overhearing tutor lose their mind trying to (unsuccessfully) explain why this didn't work.

In 2010, it was my first client project. Our architect was not from iOS background, we had editable pdfs in our app. Those were pretty rich pdfs with inline HD images. iPads that time were not too fast and couldn't handle big gb pdf loaded into memory. App would crash randomly running out of memory. We fixed it by paginating pdf, it wasn't out of the world but considering it was my first mobile project and no one to guide, I thought it was pretty cool what we did there

If anything taught me that garbage collectors aren't the one true answer for memory management then it's got to be modded minecraft

It takes around 10-20 seconds only to disconnect from a game and go back to the main menu.
You also get memory leaks, which result in several second long freezes when the GC kicks in, that happen every 15 seconds.

*Awesome compile-bomb in 29 bytes*

If you want to hang up your machine, just compile this code

main[-1u]={1};

With next command line

gcc -mcmodel=medium cbomb.c -o cbomb

It will result in ~16GB executable file (if you have that memory and computer power)

When you use someone else's poorly written code in a memory inefficient language

Just found this absolute 5 head, galaxy brain implementation in a piece of code which is called in a loop by a background scheduler which has performance issues.

There are 20+ properties, some which are recursively calling other properties with the same implementation style in this class.

Constant out of memory errors have been reported for this software, I wonder why...

i remember doing this stupid thing in java which would instantiate some object every frame or something like that which would make your computer run out of memory in a few seconds

do you want to know what my genius solution was

run System.gc() every frame

i was like 8 fucking years old i didn't know what i was doing

Annoyance in C: using the same keyword for two unrelated things, process-long memory allocation and internal linkage. Looking at you, static.

The latter should really have been called "intern", just like there is "extern". Far more people would use it if it was named correctly.

History says "static" was chosen for compatibility, allowing older compilers to take new source files.

Switched from Moto E1 to Redmi note 5 pro. Deleted all junk apps like I do in Moto E which had 2Gb internal. Later realised that it had internal memory of 64Gb.

Researchers were able to store 3 bits of data per cell in phase-change memory, beating the previous limit of 1 bit per cell, IBM said. PCM competes with dynamic random-access memory.

we are learning how a disk rotates in order to preserve memory on the physical computer hardware. in order for this disk to preserve memory, it has to rotate by following laws of physics as a circular sphere with sine and cosine waves on the coordinate system. these sine and cosine waves that vibrate independently and periodically, which means that the disk rotates 10,000 orbits per second. a drill rotates 2000 orbits per second. 10,000 orbits per second is fast enough to cut your hand off in less than 1 millisecond. we are learning that this disk has to rotate so fast in order to preserve the memory which was stored by the database system with sql.

on a subject called sql databases.

I'm back! I deleted my account awhile back, but some of the older members may still remember me. I got fired for using Google Chrome if that jogs your memory.

Anyways I'm actually a developer now! I graduated college in December and started my first dev job in February. I figured I'd sign back up here to be back with the community. Hello friends!

Why is everything slow in windows even if I have a 16GB memory? Maybe because not SSD? 😑

Slow to open in windows:
- Docker, Postman, etc

Code review, intern style:

Intern: Here is my pull request ...
Colleague: I see a problem with x, y, z. Could cause memory leaks.
Intern: Oh yeah you are correct, i'll fix that in the next one.
Intern: *merged*

decided to participate in a short c++ curse at uni, just to refresh my memory about it since it seems rather important.
Got sidetracked at the preparation task, which was the usual hello world...
I'm running this in emacs now...
Like, one view is the program and under it is the shell run from inside emacs...
I dunno why... send help?
Now I'm considering how can I configure the emacs shell in a fun way.. oh dear.

Imagine the horror of learning C programming with manual memory management, pointer arithmetic and without your cool utility libraries after programming for 2 years in Python just becoz it's in the fukin syllabus!!

What the fuck! Just witnesed this at university. The guy in question is in the same cs course as me. Using edge, okay. But searching for a picture on google (a icon in that case), copy it to memory, open powerpoint, paste it, manipulate the color aellsettings to make it gray and then save it from powerpoint? That's not how you fucking do it! Fucker!

I can’t say it’s the most painful but it’s one of my recent painful lessons.

So I’m learning C and in my project I was trying to make a copy of a 2D array and I kept getting seg faults up the ass every time I tried to allocate one of the inner arrays and after a long day of debugging I realized that I was trying to allocate memory within an array that doesn’t exist so I had to create the first array then allocate memory for each inner array after.

Fucking your fucking module allocates fucking memory fucking deallocate the fucking memory in your fucking module.

Don't fucking bullshit me!

garbage collectors' lifestyle matters!

Ever eyeballed the abyss of your memory leaks? Shit, garbage collectors deserve a raise.

Unsung heroes, janitorialing thru that VM like a dung beetle, silently fucking up your perf so you can do that delicious spaghetti. Indiana-jonesing the fuck out of that memory trash can and euthanizing all that disgusting heap of pointers hanging, dangling, like... well, like garbage.

At the very least they're deterministic, unlike that Markov chain we all had the displeasure of fucking up. Amen? Amen! 🙌🏻

You gotta wonder, though, what goes through their nuggin. Do they reminisce about the potential of that half-ass-written class? Do they weep for the elegance of a forgotten function bottlenecking their job? Nah, probably just counting down the nanoseconds till their next full GC cycle. Aaah, like cold beer in Saturday barbecue.

So next time your program miraculously avoids a memory error, take a moment, put your hands up in the air and say a prayer to your garbage collector.

Silently covering for your fuckups

My boss just now: "In a 32 bit machine the memory limit is 1.6 GB. After that programs routinely crash."

What really happens IMO? He writes programs that crash when they reach 1.6 GB allocated and the architecture is 32 bit. But it's a limit of his software, not one of the OS.

"Education" system is based on memorization. If you're able to memorize stuff short term, you'll pass the exam and be considered as "educated" academic citizen, not as "memory efficient" citizen.

Let that sink in

I just stumbled upon a first game I ever programmed back in highschool. Oh the nostalgia and the urge to cringe. Apparently I thought programing a game in visual basic and leaving an enormus memory leak was a good idea. Well I guess you have to start somewhere.

When I still in college one of my friend called me
Friend : you major is CS right?
Me: yeah
Friend : I want to buy a new PC
Me : cool
Friend :just to check with you what is the price for a 512M memory?
Me : ......

it was not a technical interview.
just screening.

guy: tell me smth about redis.

me: key value, in memory storage.

guy: more

me: umm, the concept is similar to localStorage in browsers, key value storage, kinda in memory.

guy: so we use redis in browsers?

me: no, I mean the high level concept is similar.

guy: (internally: stupid, fail).

My IBM 5150 doesn't have the standard IBM Asynchronous Card in it and was replaced with a Tecram First Mate multifunctional memory expansion, serial connectivity, and printer parallel card. It has more jumpers than a suicide hotline.

Just reminiscing when back in the "old days" video games had cheats built in...

Proton men and the flying Dutchman IN AOE3...

Now have to find hackers to create trainer apps that change values in memory and bypass cheat detection...

Was playing fallout 4 a couple days ago. About 20 minutes in. The computer just shuts off. Like no power at all. I start up the computer again. Try fallout 4 again. It shuts off at the beginning video. WTF... I try Skyrim wondering if video card is busted. Skyrim runs perfectly fine. I startup Fallout 4 again. It runs. WTF...

Next day I try fallout and bout 20 minutes in power off again. Now I am assuming cooling issue and I am trying to see temps with programs. Cannot really tell.

So today I take apart my laptop and vacuum every cooling orifice out. Vacuum any dust looking crap I can see. There was dust in the fans. All clean. I run a memory test for a couple hours. Memory passes (it was brand new memory, thought maybe flaw in ram). Now I run fallout 4. Runs fine, zero issues for about an hour.

Me to myself: CLEAN YOUR DAMN COMPUTER MORE OFTEN! Okay...

In between I read about Fallout 4 causing system reboots and shutdowns due to loading and heating. Apparently something about Fallout 4 causes this more than other games. Wild... Pretty sure it was thermal shutdown protection going on.

it was my first job as an embedded engineer i was hired to write firmware for arm microcontroller that has ble radio. But the microcontroller we used didn't have FLASH it had a SRAM and an otp ( one time programmable) memory. In ble you can make a proximity beacon and When a phone passes by this beacon it will get a notification '<device_name> nearby'
. I thought it is funny if i keep device name 'MILF' (original name of device is FLIP ) so when somebody's phone is in proximity it will have a notification 'MILF nearby'. joke didn't work as nobody has their bluetooth switched on by default ,but i forgot to change it before programming otp memory.

i just buried that device and told everyone it is not working properly

The best QA in the world is your boss. He always jump in and ask you to show him something that is not completed yet. He then acts like a professional and points out the red is not red enough... You have no word, mark down all the design changes, pass a message to designer, and then, finally, You forgot what's going on in your mind!!! And it takes another hour for you to resume your memory back....

This MOTHERFUCKER was hiding from me for three FUCKING DAYS now! All the damn time I had corrupt display memory cause of it!

Context: CS and DC were accidentally swapped on the PCB! Not a hardware issue thou. The pins can be remapped in software.

What is your first memory of programming?

I remember quite vividly writing C# in a notebook at church to pass the time. I did actually use some of that code if I am remembering correctly.

For skilled mid-career engineers, dynamic programming problems, np-complete bar raisers.

For new engineers, simple questions that can't be taught in school (questions that require business prioritization)

For older engineers, questions they haven't done since college (big-O, writing algorithms from memory)

After a long time, finally I got an opportunity to participate in a Machine Learning competition.

Brushing up my memory.
And also teamed up with another colleague.
Hope, we both get to learn a lot even if we don't win.

Pretty much a sort of research work. The first assignment was: "look, we have this CAD viewer, but we would want to eventually optimize the structure of the mesh, so here's this method of minimizing the memory footprint. Try implementing it and integrating it with our application."

PS: the method is using triangle strips, where the next triangle uses two vertexes of the previous one, theoretically reducing the memory footprint of the mesh by 2/3 if the mesh is fully optimized. In the end, due to memory and performance constraints (this had to run on the first gen iPad), and overall application architecture, on the fly striping was unfeasible and gained no benefit, because striping an arbitrary mesh is a fucking hard task.

Another one was an implementation of smooth shading by recalculating vertex normals in runtime.

that feeling when you suspect there's a memory leak in your datastore...

Nothing worse than fixing a memory leak in NodeJs. UGH!

In an encryption-module, I had a bug, that caused my PC to crash, every time I tried to encrypt something.
Turns out, the loop, that appends
0-Bytes to the string, to make it Block-Cipher compatible,
Had an logical-bug in its exit-condition, that caused it to run infinitely and allocate an infinite amount of memory.

Okey, so the recruiters are getting smarter, I just clicked how well do you know WordPress quiz (I know it's from a recruiter, already entered a php quiz An might win a drone)

So the question is how to solve this issue:

Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 2348617 bytes) in /home4/xxx/public_html/wp-includes/plugin.php on line xxx

A set memory limit to 256
B set memory limit to Max
C set memory limit to 256 in htaccess
D restart server

These all seem like bad answers to me.

I vote E don't use the plug-in, or the answer that trumps the rest, F don't use WordPress

Trying to learn C and thought a easy file copy was a good start. The program read the size of the file, reserved that size in memory, can copied data there and then to the new file. For some reason I never thought that the file might be bigger then available memory... Took a couple of BSOD to find that "bug".

How is it a thing that developing a desktop app nowadays requires an enormous amount of RAM? I stared working on an electron project and the whole thing takes up 3-4 GB of RAM when running, and that does not factor in my IDE or anything else.

But the packaged app does not go over 400mb, although we have had memory leaks in the past

If my memory is correct it's tax return season here in Sweden.

When life gives you class, make as much objects as possible so that there is a memory leak in the system...

In c++, memory is like toilet; you need to flush after every use

Writing x86 assembly code in VS Code feels so weird. I mean, I'm using something that's built using crazily high level languages (JS, HTML, CSS), on top of a mammoth runtime environment (Node, V8), which is itself sitting on a modern and sophisticated operating system (Antergos), and I'm writing code that shifts bits and bytes around in memory in order to get one part of my C program to run just a little faster. Wow.

I had a guy ask me to write a simple script for a simple card memory game. He wanted it scripted in JavaScript. Already I hate my life but I say alright and spit it out to him quick. Now he wants it on the web, Android, and iOS...in JavaScript 😓😅😂

I've always thought I was somewhat lazy about not caring about plaintext password in RAM in WPF (or whatever) but then this guy made a super valid point...

I really think a hacker would just keylog at that point rather than trying to read your obscure program's memory for your password... especially if they have access to raw memory...

today my cpu was at 100% (red) ram at 96% (above 95 is memory leak) and disk 95% (almost no space left) bc i ran emulator 2 android studio projects chrome etc all in the same time

I have waitsted whole my day searching a bug with memory allocation in C++, and still don't know how to fix it! That moment, when coding took me far less time than searching that fucking bug... I feel that i missed anything, but all looks ok
I HATE C++ WITH IT'S FUCKING POINTERS!!!!!

So, vs2015 is crashing when the process gets to 2gb .... 32bit .net process memory limit strikes again!!! 80 projects in the solution & what looks a run away extension is taking the memory !!!

Come on M$ it should be 64bit on a 64bit system!!

Now the hunt for the extension that's causing it!!

Does LUA have anything similar to the GIL in Python? Because my code seemed to be updating the same piece of memory at once

Why is netbeans, or Java in general, so fucking bad at handling memory ? I mean, I'm literally doing nothing on my code and I see my IDE consuming more and more RAM, to some point it goes over 1GB so I have to close then reopen it to "flush" the memory taken...
It's 2017, how the fuck can't we still manage to actually use a correct amount of RAM when I open a barely 10MB project ??

And it applies to everything related to Java. Like Android, Minecraft and other Java based softwares...

C++ might be very good in memory management but it's an absolute pain in the ass. When the src has thousands of lines of code it's clos3 to impossible to manage the memory. The errors are so vague.

And porting the code to a new hardware is an absolute nightmare.

Not sure about friends memory... But I'll be alive in Google's Database

Why does my brain just struggle so much with Rust.

So much of the design fundamentals I've learnt over the last 10 years from doing OO in memory managed languages don't carry over very well into Rust, and my brain is sucking at coming up with alternatives, or finds the alternatives I do make ugly.

Frustration is real.

If I have to use this much unmanaged memory, why am I rewriting this in C#.

When a data scientist thinks that if his algorithm is o(n) then it's really o(n) and it doesn't matter that he placed synchronized everywhere , connected to the db multiple time with huge in memory ops inside the transaction , wrote a file and downloaded something with http client . After all it's o(n) right mister I'm a scientist genius ?!?!?

C++. Damn the pointers. It's because I learned Java before C++ and the memory management in C++. I don't get it ever, the object creation, memory allocation, deallocation and everything

I'm trying to investigate why chrome keeps crashing after i implemented web sockets to a web app.

I used windows perfmon to see the memory usage over night.

The usage between 17:30 and 01:50 is expected behaviour as this part of the app is a live data graph of the last 48 hours.

Now i have to find out why the app doubles in memory twice in a hour.

I've implemented an in memory caching system for database queries with Redis in one of the blogs I manage.

Will it work well? Or do you think it will produce issues? I have no experience with Redis yet.

Deployments, a limerick:

there once was an ops guy from New York,
who was working on deploying a fork.
the docs were weak
the code memory leaked
in a half hour all of production was borked.

When you have been heavily using 1 language for 6 months, then start a project in another - where da fuq did all my memory muscle go!

I always wanted to learn more about C and learn the dark concepts in it. But whenever i search for it ( like.. " Advanced C concepts " ) or find a book , i end up finding dynamic memory allocation and using single dimensional pointers.. Maybe i am searching it all wrong .

This is the reason why I never prefer Google Chrome!! It freaking kick starts number of threads in the background that keeps hogging your system resources!! The one memory hungry browser!!

I gave in...

I know streams are useful to enable faster per-chunk reading of large files (eg audio/ video), and in Node they can be piped, which also balances memory usage (when done correctly). But suppose I have a large JSON file of 500MB (say from a scraper) that I want to run some string content replacements on. Are streams fit for this kind of purpose? How do you go about altering the JSON file 'chunks' separately when the Buffer.toString of a chunk would probably be invalid partial JSON? I guess I could rephrase as: what is the best way to read large, structured text files (json, html etc), manipulate their contents and write them back (without reading them in memory at once)?

It never ceases to amaze me just how big 64 bit memory space is. It's so unrealistically big that on contemporary processors you can't address the middle and the size of that dead spot (the number of high bits that must be the same in a valid address) is barely worth mentioning.

Java rant...

If public field declaration is so so bad, why can't all class fields in java just be private by default? And make it a pain in the ass to expose it as public?

I can't actually remember a time declared a class field as public, it is muscle memory now... Private bla Bla Bla, return, private bla Bla, return...

!rant, but friendly advice.
I see all those jokes about Android Studio being too heavy, and while I completely agree, want to ask you guys something:
Have you increased the memory it can use in .vmoptions?
Mine lagged as hell, but was using only about 1GB of ram.
After slight change in that file, it finally started working like it should from the beginning.

TIL don't rely too much on in memory databases if your client runs development and production environment on the same machine.

Just don't

F**k companies who's apps use MySQL/MariaDB tables of the table engine MEMORY.

Seriously.

That engine *sucks* to work with as an admin. It's such a huge pain in the ass having to always dump the whole DB instead of taking a snapshot.

And if the replica restarts... Poof. Replication breaks. Cuz all the memory tables are suddenly empty!

Fml. Fmfl. Ugh.

Can someone please tell my why the fuck Windows would need 1.2 gigs of video memory? For fucks sake this is in a VM there's nothing on here but RDR2

Hello C++ / C programmers. I've noticed my professor putting the ASCII code of a character into an int instead of just using a char to store it. When he does this he's not doing math or anything with them, so is there any advantage to it? My TA mentioned something about memory alignment, but I'm not experienced enough to know how something being aligned differently in memory would help or hurt a program.

Honestly after fucking around with rust async, I do have a lot more respect for high level languages where you don't have to worry about locking memory and stuff haha. Learning promises in nodejs was a breeze, learning them in rust requires a lot more thinking :p

When windows forms required me to dispose of a certain control derivative manually using a .dispose() call because dynamic control creation was causing a memory leak in dotnet, which instead of fixing, microsoft documented, vaguely.

Multi monitor setup?
No I can keep stuff in my memory.

Today in Amy can’t remember words, I forgot the word nostalgia and instead said “pangs of wistful memory”. You’re welcome.

I still wonder which one is better to fully learn/understand. I know to code something in both, I know about the different way of how they handle memory and I know about some of their use-cases, but then again... this stupid question still pops out:

C or C++ and why?

Actually kinda sad, that there is no pure rust ui framework out there, but rather mere adaptations of c/c++ frameworks for rust. It's better than nothing for sure, it just would be nice, if i could use a framework, that doesn't create a massive memory leak, because i looked at it funny.

In particular i'm using fltk-rs, and everytime I'm applying a font to some widget, 500kb get added as leaked memory. Doesn't sound like a lot, but for one it's a dynamically built application, so the order and amount of widgets changes, and this application is supposed to run days, if not weeks.

thanks to heaptrack i was able to pinpoint that to libpango, which i'm not even interacting with directly, but rather indirectly through the api.

Annoying, that i chose to use a language for actively preventing leaks and dangling pointers and stuff, but end up leaking memory because of a dependency somewhere.

Today I felt like the grinch explaining to my team that you can have memory leaks in a garbage collected language if they keep leaving live references.

How about incompetent management? Company absolutely murders any possible increase in productivity. Laptop provided? Slow as balls. Takes minutes to log in. I get a Mac for mobile development and that's OK. SSD and adequate memory but I'm primarily a .NET Dev. Can't get on the network with a virtual machine. They won't I stall even a managed image. So can't use databases because they're all AD authenticated. Got a virtual desktop environment and that sucks worse in performance than the laptop. Add the Assault on local administration rights and the monitoring software that constantly thrashers any memory and hard drive usage and im about to quit over all this... All this decided by a non developer and not asked for our opinions. Yay large Enterprises

Lately programs have been crashing a lot on my pc, I've tried different things like disabling SWAP for a sec, BIOS changes, remove firefox and use Google Chrome, try different commands, it kept happening.

Obviously along the way I started investigating what was causing these crashes, looking through bug reports and my syslog. There was no consistency, except for 1 thing: SIGENV. Everything that crashed had a segmentation fault, now I'm not an expect and I don't know what this means or how to fix it, so I went to Google to ask for answers.

Then I downloaded memtest and ran a memory test, error palooza. Then I went to Windows and ran memory check, error palooza.

This is week 3 of this high-end gaming pc which was a huge investment AND IT HAS BEEN FUCKING WITH ME BECAUSE OF BAD MEMORY HOW THE FUCK DOES THIS HAPPEN I ALMOST STARTED TO DOUBT UBUNTU BUT IT WAS A FUCKING FAULT IN BRAND NEW MEMORY MODULES WHAT THE FUCK.

Obviously I'm pissed off. Today I'm gonna call the store that assembled it to voice my complaints.

Thank you for listening to my TedTalk.

Well ... a few minutes ago i tried to make a discord script wich is changing my status from idle to dnd to online and so on, in an infinite loop, all good until i checked Task manager and saw how much memory is using. my bad i guess in the way i wrote everything

The other day the "big boss" came to us asking for a feature.
During he speaking to a colleague I saw this guy whitening in the face.
So after some time I asked him what happens..
"He just told me to deallocate some memory (to achieve this, and do that..)"

We are writing in Python.

Started learning Android development in Kotlin.
My first impressions:
- Kotlin is good, but class syntax is not very appealing
- Overall it seems to be quite easy, at least the basic stuff
- Android Studio is a fucking memory hog, RIP my RAM
- As good IntelliJ is as bad is Android Studio somehow
- Emulator seems to be really advanced which I like

when you're struggling to build small sized firmware on your 512Kb IoT Device resulting in bootloop every time... Then you see in the manual, that you have the 4Mb model and you frashed the rom to the wrong memory address for 2 weeks resulting in a bootloop... FML

Production goes down because there's a memory leak due to scale.

When you say it in one sentence, it sounds too easy. Being developers we know how it all goes. It starts with an alert ping, then one server instance goes down, then the next. First you start debugging from your code, then the application servers, then the web servers and by that time, you're already on the tips of your toes. Then you realize that the application and application servers have been gradually losing memory over a period of time. If the application is one that don't get re-deployed ever so often, the complexity grows faster. No anomaly / change detection monitor can detect a gradual decrease of memory over a period of months.

"NO! I will not download your stupid app! That will boat my memory and chunk my battery! Just to get to that one bit of content from a service I use once in a blue moon!"

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. :'''(

Concatenation of strings in a loop (in C#). Seriously. It's just so easy and unless you are doing something memory intensive or awful (in which case I am sorry) it really doesn't do much harm if any.

C is love, C is life.
Great language.

I genuinely don't get why so many people are struggling with pointers, considering it's a pretty straightforward concept. I understand that they can be complex in simplicity, but the concept itself is much easier to understand than say, references in OOP languages(despite being the same thing under the hood).

I mean it's just a number like any other number, except that number is treated as a memory address, and the star(* - dereference operator) just takes a value, goes to the memory address that is the value, and takes a value from there.
I feel like most explanations and tutorials just try to over complicate it for no reason.

Why somebody would think that allocate huge amount of objects in the static memory make any sense?? Why??? You need to allocate a bloody database context and all the allocation of your IOC containers and keep increasing!!!

Does any of you know, what happens to Go-routines, when they are deadlocked by waiting on a channel and the channel isn't reachable anymore?
I'd assume they get garbage-collected since they'd just a few KB of memory when not in use but I can't find anything on it online.

Back at my game engine asset system and thought of a way to store images and recreate them in memory programatically rather than 'unpacking' them... Bu turned a 256kb image into 4MB... How the fuck does this keep happening?!?!

Ugh this shit is going to drive me fucking mental!

Client wants me to document the updated patch in the system... In detail. I just want to upgrade their server memory but noooooo. They want me to detail it all in step-by-step, including change impact, description task, expected time duration, back-out plan.

The first time I had to do this, it was cute. But now it's FUCKING ANNOYING ON HOW DETAIL THEY WANT ME TO PUT IN!!!

Client: "OK, so you wanna upgrade the server memory. What do you need to bring into the data centre?"
Me: "Just my laptop. I'm just configuring your underutilised server memory and upgrade it."
Client: "Good. Put that in the document, including your laptop serial #, make and model."
Me: *Screaming internally*

Friendly reminder to trim your services list with msconfig if using Windows. Services that are STOPPED are not DISABLED, and they can be brought back up when just stopped, sometimes remotely.

(This reduces chances of being bitten by malware that uses the Fax service or similar, as there are a few that have in past used often-unused services to propagate. It also reclaims a small bit of memory, and the more real memory you have, the less you page out when compiling or similar, which is slow as fuck.)

also for the love of god stop using RDP and use something that's more penetration-proof than a paper plate...

I remember when I first heard about the general concept of a stack, I wasn't quite sure how you would use it.

Now im learning about stacks in java algorithms class as well as learning about how the memory stack works in assembly class. This probably seems small to you pro devs, but ngl, it kinda blew my mind how useful this structure can be.

When you don’t allocate enough memory in c 😅

Just rebooted.. nothing running, windows claims I'm using 99% memory, but task manager shows 211MB of 16GB being the most in use

So I have this code written in node:

Function connect(){
const client = net.blahblah

client.on('close', () => {
Connect()
}
}

As the connect is called from within the close call back, it wouldn't be recursive right? Like if it disconnected a million times, it shouldn't throw a recursion error or use up a bunch of memory right? Or am I thinking about it wrong?
