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.

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!

Long ago, like 5 years, I made an app for my EX GF in symbion to track her periods. Application predict the next date when your period will come based on her cycle.
How ever after 2 month of usage she told me that application was flashing that she is pregnant. She scared shit out of herself and made me sacred a hell as well.
Later i find out that the variable i used to store number of days between last period and current date was not capable of storing value more than 40, i don't know how, and triggers negative value to be shown.

Me and my girlfriend's pillow talk about memory leaks
Me: **... So garbage collection is a means to stopping a memory leak from occuring
Gf: what 's a memory leak ?
Me: a memory leak is like when you want a pizza, and the guy gives you pizza. But you don't eat the pizza and you ask for another pizza. You keep doing this repeatedly. Until the pizza guy realizes what you're doing and decides to kill you. He then takes back all his pizzas
Gf: why would you do that though?
Me: Lazy ass programmers who don't clean up after themselves.6 -
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.

When valgrind (C Memory allocation error detection tool) aborts due to a memory allocation error...1

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.6 -
that's quite accurate :) ofc there are exceptions (looking at you two naughty bois, metaspace and off-heap allocations!), but it's true for the most of it :)

Dev: Hi Guys, we've noticed on crashlytics that one of your screens has a small crash. Can you look?
Me: Ok we had a look, and it looks to us to be a memory leak issue on most of the other screens. Homepage, Search, Product page etc. all seem to have sizeable memory leaks. We have a few crashes on our screens saying iPhone 11's (which have 4gb of ram) are crashing with only 1% of ram left.
What we think is happening is that we have weak references to avoid circular dependencies. Our weak references are most likely the only things the system would be able to free up, resulting in our UI not being able to contact the controller, breaking everything. Because of the custom libraries you built that we have to use, we can't really catch this.
Theres not really a lot we can do. We are following apples recommendations to avoid circular dependencies and memory leaks. The instruments say our screens are behaving fine. I think you guys will have to fix the leaks. Sorry.
Dev 1: hhhmm, what if you create a circular dependency? Then the UI won't loose any of the data.
Dev 2: Have you tried looking at our analytics to understand how the user is getting to your screens?

Human memory is fascinating. It’s interesting to think about the events that helped shape you into what you are. And how sometimes those events are exchanges with people who probably never gave the moment a second thought, but fundamentally changed how you relate to others.
For example: In ninth grade, I became friends with a group of seniors. Spent every lunch period together, auditioned and landed a part in a play to hang out with them. We never hung out over the weekends, but my dad had died two years before and I didn’t hang with anyone on weekends.
Then at the end of the school year, I’d actually got my mum to buy me a school yearbook and was super excited to have my friends sign it. But when I asked them to, one of them furrowed their brow and said, “Amy, we’re not really friends...”
And I haven’t trusted friendships since.
Anyway, for anyone who needs to read this right now:

Hello guys. Today I bring you my list of top 3 programs that use too much memory

So I'm making a file uploader for a buddy of mine and I got an error that I had never seen before. Suddenly I had C++ code and some other weird shite in my terminal. Turns our that I got a memory leak and the first thing that sprung to mind was "Fuck yes, I get to do some NCIS ass debugging".
Now the app worked fine for smaller files, like 5MB - 10MB files, but when I tried with some Linux ISO's it would produce the memory leak.
Well I opened the app with --inspect and set some breakpoints and after setting some breakpoints I found it. Now, for this app I needed to do some things if the user uploads an already existing file. Now to do that I decided to take the SHA string of the file and store it in a database. To do this I used fs.readFile aaaaaaaaaand this is where it went wrong. fs.readFile doesn't read the file as a stream.
Well when I found that, boy did I feel stupid :v

Most memorable co-worker was a daft idiot.
this was 10 years ago - I was working as a junior in my very first job, fresh out of uni, for a very small startup. It was me, and the 3 founders, for a very long time. Then this old (45, from my perspective then..) dev was hired.
This guy had no idea how to do the job. no common sense. the code confused him. the founders confused him. I was focusing on my work - and was unable to help him much with his. His only saving grace? He was a nice guy. Really nice.
But why was he so memorable, out of all the people I ever worked with? simple. He had a short term memory problem. Could not, even if he really tried, remember what he did yesterday.... when I asked him what his issue was, he decribed his life is like a car going in reverse in a heavy fog. "I can only see a short distance backwards, with no idea where I'm going".
Startup was sold to a big company. I became a teamlead/architect. He? someone decided he should be a PM. -
When I was in college I was working on a game in Java using Slick2D. My folks were away on holiday so I had the ability to drink in the house (I was over 18). I worked on this coursework piece whilst drinking.

The issue was fixed (quite easily tbh) but everyone in my class reminded me for the rest of the year...5 -
My boss just now: "In a 32 bit machine the memory limit is 1.6 GB. After that programs routinely crash."

I started learning to use Hadoop recently, and am running a VM with all I need installed on it (the HDF Sandbox to be exact). The VM wants 8GB to run and my laptop only has just that, except it also needs to run Windows at the same time...
At first I thought I was screwed, that I'd need a more capable computer to learn. I gave it a shot anyway, and told VirtualBox to give the VM 4GB, hoping the VM itself would use RAM swap to function. And it did!
What I didn't expect was Windows not slowing down even a bit. Turns out Windows can triple the computer's RAM with virtual memory that it keeps on disk.
So the bottom line is: my VM is using 4GB as if it was 8GB, and at the moment my Windows is using 8GB as if they were 14GB. All of this without breaking a sweat. The more you know!3 -
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)

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

Just had a meeting with a client. Client is a local company but they hired a new guy and he is a foreigner. They made a website with us. Since it is a typical corporate website with few pages and just text and images as content, we used WordPress.
The new guy is familiar with squarespace and asked me my opinion on using SS. I don't really find any issue and it was my reply. He seemed surprised and asked me "Wouldn't it be like losing your business?"
I have never considered developing WordPress as my business. Programming is my interest and profession. But my main passion is to provide solutions to anyone in need. In fact, there were many occasions where I told to clients they shouldn't buy our services and recommend other services including competitors.

As I keep saying, we should spend less time developing "better, safer" tools and practices and more time making sure the developers that use them know what they're doing. The bugs caused by lack of memory safety are rare (although often more critical) compared to the bugs caused by developers not paying proper attention to what their code does in the first place.

The past couple of weeks I've been struggling with my laptop. It regularly ran out of memory and when that happens everything runs in a snail pace. I always thought 8GB would be enough for developing software, but I was terribly wrong.
So I ordered another 8GB and installed it yesterday. Later at work I looked at the ram usage and noticed that it was up to nearly 13GB!
I have no idea how I managed to get by with only 8 for so long. 🤔
FYI: I usually have 2 to 3 IDEs and a gazillion chrome tabs open 😅6 -
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.2 -
How do you organize your downloads folder?
Personally, I make a new folder with some name(altough the name actually being useful is rare) and just select all of my files and dump them there. Finding a file sucks so much though, I can never remember their names so I just look through the folders at the icons and hope I find the file I'm looking for. This mess that is my downloads folder led to looking 5 times in a folder to find a file.

gc_collect_cycles() doesn't work either, probably because this crap thinks there is a reference for this variable somewhere.12 -
just wondering: how much of your programming / development is based on your memory and how much do you use Google just for a reminder and how much do you ude Google for the entire code?2

So to give you a feel for what evil, clusterfuck code it was in: this projects largest part was coded by a maniac, witty physicist confined in the factory for a month, intended as a 'provisional' solution of course it ran for years. The style was like C with a bit of classes.. and a big chunk of shared memory as a global mud of storage, communication and catastrophe. Optimistic or no locking of the memory between process barriers, arrays with self implemented boundary checks that would give you the zeroth element on failure and write an error log of which there were often dozens in the log. But if that sounds terrifying already, it is only baseline uneasyness which was largely surpassed by the shear mass of code, special units, undocumented madness. And I had like three month to write a simulator of the physical factory and sensors to feed that behemoth with the 'right' inputs. Still I don't know how I stood it through, but I resigned little time afterwards.
Well, lastly to the bug: there was some central map in that shared memory that hold like view of the central customer data. And somehow - maybe not that surprisingly giving the surrounding codebase - it sometimes got corrupted. Once in a month or two times a day. Tried to put in logging, more checks - but never really could pinpoint the problem... Till today I still get the haunting feeling of a luring memory corruption beneath my feet, if I get closer to the metal core of pure C.1 -

Guys, I need some inspiration. How are you dealing with memory leaks, i. .e identifying which component of the system is leaking memory?
Regular method of dumping ps aux sorted by virtual memory usage is not working as all the processes are using the same amount of memory all the time. This is XEN dom0 memory leak, and I have no more ideas what to do.
Is it possible that guests could be eating the dom0 memory?15 -
To anyone with good knowledge of RxJs:
Should I be careful how many subscriptions I have open at a time? I'm specifically thinking about memory usage.
While obviously it's more, does it make a huge impact on memory usage, if I have 20 subscriptions active, compared to 2?5 -
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!!!

The problem with moving Docker containers from your decked-out dev machine to a VM on AWS when your boss has told you to keep costs down:

Go to hell elastic cloud!
While true:
I can’t resize my elasticsearch instance to get memory because it’s stuck….
It’s stuck because it doesn’t has enough memory to actually start …
Wtf!2 -

I can't really figure out how I grew from learning_syntax -> remembering_function_names -> following_patterns -> developing_a_personal_style -> reading_the_doc -> getting_the_source.
Well I have a long memory problem, so I guess it happened overnight!
Wait, did the doctor say it was a memory problem? Hell no! -
So there's a proposal for C++ to zero initialize pretty much everything that lands on the stack.
I think this is a good thing, but I also think malloc and the likes should zero out the memory they give you so I'm quite biased.
What's devrants opinion on this?

Does anybody use raspberry pi as Kubernetes node? I kinda have an experience of my pis do not have enough memory with 1Gb. The system would run about 5 minutes, and each second more memory would be allocated. After that, every node shut itself down. Is there anything I can do about that?2

That realization that you have a memory leak that invalidates all of your previous performance testing1

Back in game dev final year, working on GameCube kits, I encountered a weird rendering bug: half the screen was junk.
I was following the professors work and was bewildered that mine was broken.
The order of the class (c++) was different...
I think there was a huge leak somewhere and the order of the class meant memory was leaking into VRAM. I never had the chance to bug hunt to the core of it... Took a while to realise it was that...
It opened my eyes to respect memory haha.2 -
Customer: your app is not returning all the objects in my bucket
Support: check console log 500 server error, ssh into box check logs exhausted memory limit.
Sudo vim /etc/php.ini search memory limit
Update to a high number restart Apache sit back and think fuck did I set it to high will it blow up my server.
Only time will tell!!! Sorted out the issue until the next user with millions of objects in their buckets -
Memory debugging iOS probably makes me more anxious and stressed out than anything. I have put 11

I actually don't understand why most people like saying bad things about electron-js been a memory hog. I am not denying the fact that it sucks up system resources. Placing all the blame on electron-js is irrational because most apps built untop of electron-js does not hug memory (vscode is a living testimony to that). When you use bloated frameworks and/or libraries you are bound to have memory issues. When you don't understand how to manage memory effectively (in higher level language - you still have to do something for your value to be garbage collected) you are bound to be held captive in the chains of memory consumption.
Don't hate electron8 -

- Debugging some application locally (with debugger)
- 20-30 manual step-ins, tracking those values VERY closely
- debugger becomes a little sluggish
- move mouse to select a line to jump to
- cursor is lagging: all jumpy and everything
- CTRL+ALT+F1
- everything freezes.
sooo...either reboot the laptop and lose all the work, or wait for OOMK to kick in, which could be hours, depending on the level of memory starvation.13 -

What a mess ^^
From one moment to another unit-tests on my local machine stopped working.
There was a PHP fatal error, because of insufficient memory.
Actually, there was a ducking "unit"-test of a controller action "log".
This action returns the content of the projects log file...
Since this log file grew over the time, PHP tried to assert the response of the controller action which was sized about 400MB.
C'moooooon guys!
What were your thoughts behind this bullshit? ^^ -

Feel dirty writing in c. How do people even deal with unsafe pointer type casting/memory allocation/free? The codebase is plagued with memory leaks and there is no test.
I will just pretend I can't read c code and play dumb when shit happens12 -
You know what really grinds my fucking gears?
When I increment my pointer beyond the memory the operating system allocated it.
Who are you to define how much memory my pointer is allocated? You fucking bigot!1 -
Why the ever loving fuck does Windows take MORE ram to close a fucking program, than to run it. I'm STOPPING a fucking operation. There is nothing about this concept that requires more processing or memory. When I click the fucking close button, you're supposed to free up memory and stop running shit. Not the opposite.3

Why TF does nodejs just eats 100mb of ram away for a simple application with ONE websocket connection ? I've tried getting some heap snaps, memory allocation timelines and used memwatch-next, but to no result AT ALL! Since the heap stay small but the rss memory grows like there is no tomorrow.

I'm having a laptop which is powered by i5 3230M with 6G memory (1 x 4G and 1 x 2G). Sometimes I can feel the lag while I'm working on multiple IDEs. So, how much more memory do you guys suggest?
(2 x 4G) or (1 x 4G and 1 x 8G)19 -
It's pain in the ass, when you finally managed to free enough memory to keep your android os up-to-date and just a few minutes after update restart getting a message that there is an os update, which needs another 200mb.

Hi Everyone,
I am working as a jr front end developer and wanted to study more about performance profiling in Chrome and finding memory leaks using Dev tools. I searched online for a while and not able to find a nice place to start with, can anyone help me out with a resource from where I can start the debugging performance using Chrome Dev tools.
It would be very helpful. -

TL;DR When talking about caching, is it even worth considering try and br as memory efficient as possible?
Context:
I recently chatted with a developer who wanted to improve a frameworks memory usage. It's a framework creating discord bots, providing hooks to events such as message creation. He compared it too 2 other frameworks, where is ranked last with 240mb memory usage for a bot with around 10.5k users iirc. The best framework memory wise used around 120mb, all running on the same amount of users.
So he set out to reduce the memory consumption of that framework. He alone reduced the memory usage by quite some bit. Then he wanted to try out ttl for the cache or rather cache with expirations times, adding no overhead, besides checking every interval of there are so few records that should be deleted. (Somebody in the chat called that sort of cache a meme. Would be happy , if you coukd also explain why that is so😅).
Afterwards the memory usage droped down to 100mb after a Around 3-5 minutes.
The maintainer of the package won't merge his changes, because sone of them really introduce some stuff that might be troublesome later on, such as modifying the default argument for processes, something along these lines. Haven't looked at these changes.
So I'm asking myself whether it's worth saving that much memory. Because at the end of the day, it's cache. Imo cache can be as big as it wants to be, but should stay within borders and of course return memory of needed. Otherwise there should be no problem.
But maybe I just need other people point of view to consider. The other devs reasoning was simple because "it shouldn't consume that much memory", which doesn't really help, so I'm seeking you guys out😁 -

I always referred to disk space as memory. Here's how a casual chat with my friend would be like:

Spend like 3 weeks in mem-checking with valgrind and ASAN, because there seemed to be some leaks. So painful and scary. You loose all confidence in your software, the checking tool, your own sanity.
Some spurious result prevailed, could only move it around. Boss could not reproduce the problem on his machine; Ubuntu 18 with GCC 7, mine was Debian 9 with GCC 6, so I tried older Ubuntu with GCC 5. Also no problem.
Fuck it, I'm switching to clang.
