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.
Early days of my programming, Shit happens.8 -
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.

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.15

The world of storage gonna change..

am I only one who thinks that ≥6GB RAM for phones is just too much as most of the time the unused RAM gets wasted for no goddamn reason but the only one being that the companies want their product(s) to look more compelling in `spec sheets` and it's a competitive market so it ok for them to do so...

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?

Java dev here. I rewrote an app and replaced a system call to ssh with a modern jaxrs post for uploading a file and (new) some additional data.
I even used a stream.
1 hour in production, first client doesn't get his file. Log says OutOfMemoryError: heap.
Me: wtf? I already use streams.
Looking at the Jersey library. Docs say nothing. An issue from 2013 says: oh if you silly don't use the Apache httpclient addon, we disable chunking and buffer the whole body, because our tests fail with the jdk included http client otherwise.

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

Medium long story about POP!_OS
TL;DR : A true K.I.S.S. OS. Very well designed UI. In general suitable for everyone. Any distro-hoppers MUST try out. If your current OS is already heavily customized to your needs, DON'T bother with POP. (Read till the end if you are on toilet, nothing to lose)
Backstory : I am never a fanboy of anything although I am loyal to the tools I use daily. So OS is also something I picked and use to meet my needs except when I was a student. My first linux experience was about a decade ago with ubuntu. Have tried almost all kinds of light-weight and minimal distros after that (lubuntu, arch, mint, puppylinux, fedora, centos and others I forgot) during my student years.
I like all things minimal. ("Keep It Simple Stupid" is my email signature.) When I started working, Windows became the sole OS I use since it met my needs better than others. Except that one time when I tried Elementary. Although I found it a good OS, it didn't get installed as a dual-boot. I don't find Elementary minimal. It is one of well designed OSs but I still think it can be improved. (Plus I had this weird feeling that it is similar to Mac OS)
At the start of this year, Widows alone was not enough for my needs. Decided to look for a minimal linux distro. My old i7 ASUS has 8GB RAM and roughly 250GB free storage. So I am not that worried about hardware requirements. My main struggle is downloading stuffs. (Few of you guys must know by now the speed of my internet LOL.) Well, even if I had a good speed, I will still look for minimal distro as first priority. So I went with minimal ubuntu image and xubuntu environment. Although I do not like the UI design, it is acceptable. Through out the years, I have configured it to suit my needs and currently pretty happy with it.
Thoughts on POP!_OS : To me, it is literally like meeting a young girl who is perfect for my life. She has the perfect body, beautiful face, amazing appearance and good manners. And she is young, of course there is a lack of experience issue. But it can be taught and she has a very high chance to become a wonderful lady if she continues like this. Only crap is I already have someone and in a committed relationship. So I could not go any further than introduction. I do save her contact and will keep in touch with her online. You know? Things change. Things always change somehow.2 -
When I did games dev in college, it’s fair to say that most of my class started off really stupid. Like, I met these people. We were all dumb.
Except this one guy. His name was Jordan. He was huge. He smelled bad. Everyone made fun of him, (I kept my distance in fear of being decimated because he was known for his temper).
But fuck, that guy knew how to model and code. In the time we had spent working out how to build a single model or write a working line of code, he’d been working on this full scale Skyrim-esque environment that just reminded me of Whiterun.
I wonder what he’s doing now. -
i'd rather burn a site to the ground to preserve it in its current state than let it devolve into a place for SJWs to basically outlaw everything because they're special snowflakes. It's about breaking video games, you don't need to say "well you can't use he/she/him/her pronouns ever, you can't acknowledge binary genders, you can't say the word 'retarded' even when referring to the dictionary definition of the word (synonym of regression), you can't send PMs at all because privacy is against God, you can't say/reference God or Christianity because #NotAllReligions"

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:

Not really a rant and not very random. More like a very short story.
So I didn't write any rant regarding the whole Microsoft GitHub topic. I don't like to judge stuff quickly. I participated in few threads though.
Another thing is I also don't use GitHub very much apart from giving 🌟 to repos as a bookmark. Have one hobby project there. That's all. So I don't worry that much. I'm that selfish and self concerned. :3
I was first introduced to version control system by learning how to use tortoisesvn around 2008. We had a group project and one of the guys was an experienced and amazing programmer unlike the rest of us. He was doing commercial projects while we were at our 1st and 2nd year. Uni had svn repo server. He taught us about tortoisesvn. He also had Basecamp and taught us how to use it as well. So that's how I learned the benefits of using versioning tools and project management tools. On side note, our uni didn't teach any of those in detail :3
After that project, I was hooked to use versioning tools. So until school kicked me out, I was able to use their svn server. When I was on my own, I had to ask Google for help. I found a new world. There are still free svn services that I can use with certain limited functions. That's not the new world; I found people saying how git is better than svn in various ways. It was around 2010,2011.
At first I was a bit reluctant to touch git because of all the commands in terminal approach. But then I found that there is tortoisegit. I still thank tortoisesvn creator for that. I'm a sucker for GUI tools. So then I also have to pick which git servers to use. Hell yeah, self hosted gitlab is the way to go man. Well that's what the internet said. So I listened. I got it up and running after numerous trial and error. I used it briefly. Then I came back to my country on 2012-2013; the land of kilobytes per minute (yes not second, minute).
My country's internet was improved only after 2016. So from 2013 to 2016, I did my best not to rely on internet. I wasn't able to afford a server at my less than 10 people, 12ft*50ft office. So I had to find alternative to gitlab which preferably run on windows. Found bonobo and it was alright. It worked. Well had crazy moments here and there when the PC running Bonobo got virus and stuff. But we managed. We survived. Then finally multi national Telecom corporates came to our country.
We got cheaper and faster mobile data, broadband and fiber plans. Finally I can visit pornhub ... sorry github. Github is good. I like it. But that doesn't mean I should share my ugly mutated projects to the rest of the world. I could keep using Bonobo but it has risks. So I had to think for an alternative. I remembered that gitlab didn't have cloud hosting service when I checked them out in the past. So I just looked into Bitbucket and happy with their free plans of 5 users and unlimited private repos. I am very very cheap and broke.
That's why I said I don't really care that much about the whole M$GitHub topic at the beginning. However due to that topic, I have visited GitLab website again and found out they have cloud hosting now and their free plan is unlimited users and unlimited repos. So hell yeah. Sorry BB. I am gonna move to cheaper and wider land.
TL;DR : I am gonna move to GitLab because of their free plan.4 -

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 -

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. -

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.
My DOS VM is more organized than that...
Speaking of DOS managing memory in that is hell. I've never had memmaker detect 64MB of RAM, giving the VM 96MB of RAM made it detect 2 more MB or something.5 -

Didn't participate in this week rant since the topic is not very relatable to me.

A full 4 level page table on x86_64 is over around 687 GB in size. Allocating it fixed size obviously won't work...
So now when allocating virtual memory pages for an address space I sooner or later have to allocate one page to hold a new page table... which has to be referenced by the global page table for me to use... where there isn't any more space... which is exactly the reason we allocated a new page in the first place... so I'm fucked basically9 -
I have gotten so used to editing files in vim that I invariably type vim commands into editors which don't use them (which is pretty much every other one.)
I can't count the number of times I've sent ZZ or :q to a colleague in Slack or typed /word in an email or even D when I was trying to delete a line.
Then I spend time outside of vim and find myself using the cursor keys or mouse to move around.

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.5

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.
He probably thinks I'm a strange guy. -

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.

Many of these kind of games suffer from one specific issue, they crash during a long drawn out game.
And guess what, this one isn't any different !

> Failed to allocate memory
Game only appeared to be using some 6Gb, and I've 24Gb, so nice ECC memory too, just so my game doesn't get ruined by any cosmic particles..
So, does anyone code a game like this, which doesn't crash after you've spent hours building up your forces/etc..
Or do I have to write my own !7 -

So in Ruby, everything is passed to functions by value. However, when you manipulate objects, you're actually manipulating references. A simple example:
```
a = [3]
b = a
c = a
b.push(2)
print a
print b
print c
# => [3, 2][3, 2][3, 2]
```
Here's a more complicated example from the problem I was solving:
```
table = Array.new(5) { Array.new() }
1.upto(5 - 1) do |i|
1.upto(5 - 1) do |j|
table[i] = table[j]
end
table[i] << rand(1..6)
end
```

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 -
I went to bed and before sleeping opened an app on my phone that controls the music on my PC.
At first glance it looked like something was different so my first thought was "Ooh, they updated the app" and then I remembered that no, I didn't. I'm a lazy sack of crap that didn't update that app in a while and I didn't even implement everything.
On the plus side, I did actually get the basics working so... :D -
I usually like PHP, because it is easy to use, but FUCK! Can you just let me free the fucking memory by myself? Setting variable to null doesn't work, unset doesn't work either. I am still getting fucking memory exhausted error.
There is literally no data stored anywhere, because I unset every fucking thing.
gc_collect_cycles() doesn't work either, probably because this crap thinks there is a reference for this variable somewhere.12 -

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 -
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 😅7 -

Meditation. Or Awareness Meditation to be precise. It enables me to regain control over my mind, because I get distracted really fast. It really helps sorting things out, taking a step back and getting an overview where I actually am and if what I'm doing right now is actually relevant/has priority. I mostly find that it's not, so I have to return to the important stuff.
For those interested: meditation sounds weird, even obvious at first or you just don't get what's it all about. You actually have to practice meditation for a long time and study the concepts until you start to understand what all these phrases and talking means. Behind them lies great wisdom/huge amount of concepts which is easily underestimated. So don't be frustrated too much if you don't feel it working right away. Be assured I've been there too. Also don't start with meditations like 'just stop thinking or think nothing' because in my opinion this is highly complex shit and frustrating at first. Start with awareness or breathing meditations or even get an app to support your daily habit.1 -
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 -

- 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

- 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 -
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 -

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!

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😁 -

- you send back exactly what's changed (which is exactly what was being asked, but naming things as they are, clearer than I can ever explain changes),
- you go to the person that has assigned the very thing, explain it, he seems to get it,
...
Then.. a few hours later.. you get a reply via mail:
"Come explain what you're saying here, because I don't get it."

Topic: Linux (Ubuntu) on eMMC drives.
Long story short: https://youtu.be/VvmROT8LEsM
I'm pretty new to linux and my primary computer is running on windows, but I wanted Linux back again (Had it once for a short time) so I decided that my Win10 Laptop (Acer Aspire 1) has to be sacrificed to satisfy my needs.
Unfortunately it has an eMMC drive so I did a little research and found out that a lot of people had issues with them, but YouTube spit out that poorly made, but we'll explained video.
If someone else isn't sure about Linux running on eMMCs watch the video and follow the instructions.
Btw I'm using the latest Ubuntu Budgie atm.
