Today, I was told to investigate why the software doesn't work on "some" computers. I had no previous experience with that particular software but I just had to make some tests... easy, right? As soon as I ran the software, my computer crashed (I literally had to restart the pc). I asked my colleagues if I did something wrong but the set up seemed ok.

Later, in a random discussion about the software I found out it does "a little memory allocation". I opened the performance tab in task manager and ran the software again. In an instant, the RAM went from 1.3GB to 7.66GB (my pc has 8GB of RAM).

In an attempt to find how such a monstrosity was creater, I found out the developer that made the software had 16GB of RAM on his pc.

I have found something that eats RAM more than Chrome... brace yourselves.

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

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

The allocation of my time while 'programming':
50% Reddit
25% Stack Overflow
24% Error messages
1% Actual coding
100% Frustration

Okay, just wrote a program with memory allocation inside an accidental infinite loop and by the time I was able to kill it, it had already claimed 86% of my memory. Scared the shit out of me because my OS was CRAWLING for a while

Ladies and gentlemen... Can we please have a moment of silence for my PC which seems to be on her last legs...

CPU thermal throttling at 40 degrees celcius (CPU is on it's way out)
RAM is randomly having allocation errors
PSU isn't delivering optimal current
GPU only displays out of 2 DP ports

and for the very first time... Have had an SSD fail...

Pray for me people... Please

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.

Help.

I'm a hardware guy. If I do software, it's bare-metal (almost always). I need to fully understand my build system and tweak it exactly to my needs. I'm the sorta guy that needs memory alignment and bitwise operations on a daily basis. I'm always cautious about processor cycles, memory allocation, and power consumption. I think twice if I really need to use a float there and I consider exactly what cost the abstraction layers I build come at.

I had done some web design and development, but that was back in the day when you knew all the workarounds for IE 5-7 by heart and when people were disappointed there wasn't going to be a XHTML 2.0. I didn't build anything large until recently.

Since that time, a lot has happened. Web development has evolved in a way I didn't really fancy, to say the least. Client-side rendering for everything the server could easily do? Of course. Wasting precious energy on mobile devices because it works well enough? Naturally. Solving the simplest problems with a gigantic mess of dependencies you don't even bother to inspect? Well, how else are you going to handle all your sensitive data?

I was going to compare this to the Arduino culture of using modules you don't understand in code you don't understand. But then again, you don't see consumer products or customer-specific electronics powered by an Arduino (at least not that I'm aware of).

I'm just not fit for that shooting-drills-at-walls methodology for getting holes. I'm not against neither easy nor pretty-to-look-at solutions, but it just comes across as wasteful for me nowadays.

So, after my hiatus from web development, I've now been in a sort of internet platform project for a few months. I'm now directly confronted with all that you guys love and hate, frontend frameworks and Node for the backend and whatever. I deliberately didn't voice my opinion when the stack was chosen, because I didn't want to interfere with the modern ways and instead get some experience out of it (and I am).

And now, I'm slowly starting to feel like it was OKAY to work like this.

So yeah, I think it’s broken

You know what just gets to me about garbage-collected languages like c# and Java? Fucking dynamic memory allocation (seemingly) on the stack. Like it's so bizzare to me.

"Hey, c#, can I have an array of 256 integers during run-time?"

"Ya sure no prob"

"What happens when the array falls out of scope"

"I gotchu fam lol"

Well done, Google Chrome, you ate most of my 16 GB of RAM! >:v

P.D. I said "most of" because of the memory allocation table

My brain power allocation:
- 1% — happiness
- 1% — creativity
- 1% — work
- 97% — picking out insignificant details in my past and feeling anxious about them, imagining what could’ve been, or rigorously planning out completely hypothetical scenarios

Using old style C allocation in C++ be like

University Coding Exam for Specialization Batch:
Q. Write a Program to merge two strings, each can be of at max 25k length.
Wrote the code in C, because fast.
Realized some edge cases don't pass, runtime errors. Proceed on to check the locked code in the Stub. (We only have to write methods, the driver code is pre-written)
Found that the memory for the char Arrays is being allocated dynamically with size 10240.
Rant #1:
Dafuq? What's the point of dynamic Memory Allocation if you're gonna fix it to a certain amount anyway?
Continuing...
Called the Program Incharge, asking him to check the problem and provide a solution. He took 10 minutes to come, meanwhile I wrote the program in Java which cleared all the test cases. <backstory>No University Course on Java yet, learnt it on my own </backstory>
Dude comes, I explain the problem. He asks me to do it in C++ instead coz it uses the string type instead of char array.
I told him that I've already done it in Java.
Him: Do you know Java?

Rant #2:
No you jackass! I did the whole thing in Java without knowing Java, what's wrong with you!

Anyone else taking Harvard's CS50 via edX? It's so awesome! You get a better understanding of Computer Science and stuff. I'm loving C! It feels so close to communicating with the machine. Memory allocation fascinates me, too. Is this why it's fast? If you feel like you're lacking with the CS fundamentals although you can build apps or websites already, I recommend this. This is better than my whole years in college!

Well I'm a first year student in computer science and in the first semester we started to learn C language and the IDE they told us to use for better learning was Devcpp.
We made a few small projects and all went well, but now in the second semester we started to make bigger projects with linked lists and memory allocation and Devcpp starts to be a complete bug itself... We are working hard in the project and after saving the project with no errors at all, at the next day, Devcpp starts to make any function we made invalid...
So we spoke to the same teacher about this and asked what can we do about it....
"Are you using Devcpp? You shouldn't, it is not that good for C"...
ARE YOU KIDDING ME?

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.

52 min Are you fxxxxx kidding me.
Thumbs up Optimization of the decade

Assignment release: this is a basic assignment that is supposed to help you understand the basics of memory allocation. You are free to use any design you want, however you can implement more advanced features that would lean towards specific designs. What will be punished is that you don't have a dynamic memory allocator. We will run the tests for these offline after the deadline

2 days before the deadline: we released the tests for checking whether you're allocating memory dynamically, but these tests also check for this specific design. So fuck you for choosing any other design than this one. Have fun on sleepless nights.

Fuck me, I guess, for worthlessly working on a different design than they wished for, but didn't specifically ask for from the beginning. I just wasted 2 weeks of my life and feel unmotivated af to do anything anymore regarding this. Fuck this shit. Fuck them. Fuck this course.

I've been using arch for like 2 months now. And I can even play games on it quite smooth (cs and stuff). But I'm missing Witcher 3 and Rise of the Tomb Raider. So I took all my courage and booted into win10. Guess what they welcome me with...

Edit: this was after the 5th reboot. Now I'm getting fucking bsods like nothing because of bad memory allocation :( fuck this shit. Has anybody of you got a working windows PC? I just want to playyyy 😢

How important is understanding heap vs stack memory allocation?

Who knows--I'm a python developer after all.

Also I completed by first alife simulation. Took me from 7 pm yesterday to 10.30am this morning.

Feels good. I'm at the part of familiarity with the language that my thoughts are pretty much directly parsed and translated into code, without any effort.

Alife's just for the standard math shitposting though. Was fun regardless.

Avoid ACPICA if at all possible. It's one garbage tier cluster fuck of bad design, horrible documentation and downright misleading and wrong code

It's meant to consist of an ASL compiler, disassembler, debugger, dumper, various user space utitilies and a kernel resident OSPM implementation *if* you can figure out what belongs to what. Even just compiling this pile of trash is a mystery in itself. Think you need the source files in source/common? EEEEH, wrong. Well, at least partially since most of them seem to be for the user space stuff..? Other ones *are* needed on the other hand. At least the disassembler and/or debugger and/or dumper components seem to reference them. Not that I could figure out how to compile those anyways. The real path to your goal seems to be to ignore a seemingly arbitrary subset of source and header files until your linker stops complaining

There's also a bunch of configuration defines, some of which *you* define, some defined *for* you, based on again others. Of course most of them do stupid shit. Enabling the debugger automatically enables debug logging. Enabling the disassembler force enables debug allocation tracking... What?

The code itself isn't of much help either. Looking in "os_specific/service_layers" you find what looks to be reference implementations of acpica functions in certain os' like windows and unix. Of course I had a look because AcpiOsReadMemory is supposed to read physical memory and I don't know how I would even implement that. But hey, osunixxf.c (xf for interface... of course) should tell me. I'll let you see for yourself in the attached image. Apparently it does fuck all and just returns AE_OK. No error, no logging, no nothing. Just ok. As you can imagine, AcpiOsWriteMemory doesn't do much more either.
...okay so maybe physical memory accesses aren't actually used and these functions are some sort of relic from past times? Nope! They are absolutely necessary for doing low level device interaction. WTF. So finally I went to the linux source and checked how *they* implemented them, and just as I thought, these functions are anything but no-ops...
...So for what fucking reason do these stupid interface implementations even exist but to purposefully mislead you?? They aren't used for fucking anything! As far as I know Windows doesn't even *use* ACPICA and Linux have their own fork with working implementations... They just sit there, just to tell you how to NOT do it

So that's some of my thoughts about ACPICA. Note that I haven't even used it as a library yet, I just got it to compile and link and it already fucked with me this much.
There's also so much more I didn't mention like that you *have* to modify the acpica source in order to get your own platform header working (else #error) eventhough the docs explicitely instruct you not too but you get the point

Don't use ACPICA if you don't have to. Save your sanity for something that's worth it

You know shit is going to hit the fan if the sentence "c++ is the same as java" is said because fuck all the underlying parts of software. It's all the fucking same. Oh and to write a newline in bash we don't use \n or so, we just put an empty echo in there. And fuck this #!/bin/bash line, I'm a teacher. I don't need to know how shit works to teach shit. Let's teach 'em you need stdio for printf even tho it compiles fine without on linux (wtf moment number one, asking em leaves you with "dunno..") and as someone who knows c you look at your terminal questioning everything you ever learned in your whole life. And then we let you look into the binaries with ldd and all the good stuff but we won't explain you why you can see a size difference in the compiled files even tho you included stdio in the second one, and all symbol tables show the exact same thing but dude chill, we don't know what's going on either.
Oh and btw don't use different directory names as we do in our examples. You won't find your own path, there is no tab key you can press to auto-fill shit.
But thats not everything. How about we fill a whole semester with "this is how to printf" but make you write a whole game with unity and c#. (not thaught even the slightest bit until then btw)
Now that you half-assed everything because we put you in a group full of fucks who don't even know what a compiler is but want to tell you you don't know shit and show you their non-working unfinished algorithms in some not-even-syntax-correct java...

...how about we finally go on with Algebra II: complex numbers, how they are going to fuck up your life, how we can do roots of negative numbers all of the sudden and let you do some probability shit no one ever fucking needs. BUT WHY DON'T YOU KNOW EVERYTHING ALREADY HMMMMM, IT'S YOUR SECOND LESSON, YOU WENT TO SCHOOL PLS BE A MATH PRO ASAP CUS YOU NEED IT SO MUCH BUT YOU DON'T NEED TO KNOW PROPER SYNTAX, HOW MEMORY MANAGEMENT WORKS, WHAT A REFERENCE IS AND PLS FINALLY FORGET THE WORD "ALLOCATION" IT DOESN'T PLAY A SINGLE ROLE YOU ARE STUDYING SOFTWARE DEVELOPMENT WHY ARE YOU SO BAD AT ECONOMICS IT MAKES NO SENSE I MEAN YOU HAD A WHOLE SEMESTER OF HOW TO GREET SOMEONE IN ENGLISH, MATHS > ECONOMICS > ENGLISH > FUCKING SHIT > CODING SKILL THATS HOW THE PRIORITIES WORK FOR US WHY DON'T YOU GET IT IT MAKES SO MUCH SENSE BRAH

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!!!!!

My most humbling experience was finding the source code online to the original Pokemon games. It was right after I had finished my first text based Linux console game and I was looking up other programs source codes just for shits and giggles. Most of them were simple and I learned a few simple tricks but the red and blue Pokemon were the first codes I saw that fascinated me. The addressing, the memory allocation, even the simple audio processing was simply genius. So many unique innovations and techniques. If I achieve 1/5th of the skill I found in those files, I can die a happy programmer!

When you realize the Linux kernel overallocates memory like United Airlines overallocates seats on a plane.

But for some reason we're ok when Linux does it.. less ok for an airline. >_<

Oh my, never was i triggered more. Of course i can only speak for my experience. I study software development as focus.

First off, the starting languages and or concepts you learn.
Why the fuck do they start with java and don't even really explain how instances actually work? Of course they don't. Because it would be way too fucken much for a semester to go over garbage collection, Instanciation of stuff, allocation in such an advanced system, etc..
How about starting with something not 50% managed by a vm?
Good ol' C. And now don't tell me thats a rough start. We all know about these subjects or exams where it's all about sorting people out. Who will be able to manage a whole bunch of shit or who should consider something else.
Yo dawg sick idea: how about sorting it via the will to achieve the skill of coding?
Nah but we make the exams around coding (by the fucking way done on paper, what the hell) such a fucking breeze, asking you how to convert hex do dec.
Meanwhile maths will make you cut yourself in a dark corner, after you nearly shot yourself because of some lame-ass business-subject.

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 .

My life is a failed checksum test :(
(The L3 allocation is not the issue)

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 got a phone interview!!! Hope it goes better than my last one :') that one was for a web developer position and they asked me about stack vs queue and memory allocation. Idk why but I sure as shit didn't get the job.

Why is 99% of my development job responding to audits, security questions, and idiocy spewing from something called an “Office of Innovation”? So this Innovation team sends down a project request which is silently intended to push my resource allocation over 100%. Security shoots down the idea. Innovation team tells me to tell security no, we need this. Ummm, here’s a thought, why don’t you idiots all get together and tell me when there’s some coding to be done?

At work we develop for embedded systems. Using the heap can raise unknown effects sometimes. So we always try to avoid using it. To show our attitude regarding the heap we want to make T-Shirts like the No Ma'am shirts from Married... with Children but with No Heap instead of No Ma'am. Now we need a meaning of the acronym. Our currently idea is:

Nerdy
Opponents of
HEAP
E
Allocation
Practice

We do not find a good word for the E, we also aren't native speaker, thus we are not sure which synonym for word like based can be used in such context. So i want to ask if someone has a good idea or even a better idea for the whole acronym :)

So basically I am the computer guy in my office. If there is any hardware or software related problem, I am the guy who fix it or try to fix it in my own time.

Little bit of more backstory. Two month ago we got react native project from a client. My boss asked me if I want to do that project. he knew that I don't know react native but I want to learn it. So I said yes. I have worked over 12 hours per day to work on that project while learning react native ( I committed the final version to git today.)

Yesterday there was a meeting in our office about project deadlines and issue with current work and stuff. In that meeting one guy asked (this guy had personal beef with me) in rude way like why I am taking parts of pc and given other people. ( If there is any hardware issue, I use other parts from pc which are not currently in use. So basically a simpe resource allocation.)

I knew it was a targeted questio toward me but before I say anything, All people took his side. (I did all those repair after taking permission from my boss, so he did not take that question seriously.)

I spend lots of time fixing those problem so people work does not stop and this is the thank you I got in return. I did this over one and half year. Right now I am asking my self if I continue the work or not.

Note: I wrote this whole thing to get my anger out of me. Sorry for typos. I am little bit drunk and I am not good with English.

I wonder the creator of jQuery , Objective C , Erlang, what were they smoking while creating these programming languages......

Whenever I code in Erlang (server side) or Objective C (iOS) I can feel that the creator is damn high...

Objective C is weird that I have to call an object by allocation . Like get me thinking is that OOP? Or Functional.

Compilers should just work for raw C with only static memory allocation. This isn't the bad old days where a couple of dudes wrote a short book explaining how C might probably should possibly work. I hear supposedly we have standards now.

Well, last week I lost 2 days to our compiler randomly forgetting that it wasn't okay to put a globally allocated uint32 at an address ending in 9. What? It had been handling this case without issue for more a year, but now after changing completely unrelated code we have this problem.

I'm not sure how to even deal with this idiocy so no doubt I'll continue working on it this week, too.

Thanks a lot, GCC.

Folks,
I've copied a folder(size: 10.7GB) to external HD, and it's occupying 154GB on external disk.

yes, the folder has a lot of small files in it. but ..

Surprisingly, the same folder occupy 10.8GB on internal HD. and that drive is not compressed.

I defragmented external HD, problem still unresolved.
* allocation unit size is default(4096B) on both the disks. both are NTFS

Plz, help me, explain me... :-(

Fucking gdb with your stupid commands, showing me the memory allocation, shos me the data you stupid piece of shit, what is the value pointed by the pointer.

*Segmentation fault**core dumped*

Oh gdb! How much I missed you. Please don't ever leave me okay?

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!!!

I am very thankful to C as I face less pain while dealing with pointers and memory allocation and deallocation in C++. I am very thankful to C++, as I grasp OOP and template concepts out of it and it was also my first language for DSAlgo implementation. I feel very fortunate to move to Java after C++ rather than python. Although Java's design is f**ked and it feeds on a computer's memory, it taught me to deal with objects( unlike C++). It taught me how objects are clearly different than primitive data types like int, float, char...And best of all, Java provided me everything I need to safely switch to Python, it's all because of Java, I can clearly understand the working of python. All the stuff which I find weird in python before is sounding logical to me now. As java taught me how to deal with objects, I am confident to say that "I CAN DEAL WITH PYTHON". With respect to all my 3 prior languages: C, C++, and Java.

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 happens

A game taking place inside an operating system. Like Tron but needs to have much more solid analogies. User's body as tty process. Some representation of scheduler priority and memory allocation. Forking. Children and zombies. Init.

Some process-ownable token representing file handles.

Network ports as portals through which data may be sent by acquiring a file handle and using it.

/proc, /mem, etc are extreme stretch goals.

Never really started because I couldn't decide how to represent all the different parts so they would all be consistent *and* entertaining

As an extension of the extreme stretch goals, a multiplayer functionality where players can shell into each other's game worlds ("computers")

So the people in charge of staff allocation came into our room the other day and straight up stole most of the front line support team for iOS. The team now has one member, and the manager of the team found out about it 15 minutes before it happened. This was done to fill requirements on other projects that they are struggling to get staff for.
Meanwhile I've been sitting here for months wanting to get out of this project and they cant find anything else for me. All because I wont travel 4 days a week...

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.

The worst part about being a dev is having to deal with resource allocation of two hands, three keyboards, two mice 😂and a coffee all throughout life

1) Reader Rabbit on an Apple IIGS in the late 80s. I might've been in Kindergarten. Found the boxes stored in an unreachable storage area at my dad's house recently. Knowing how he took care of things, it probably still works. He won't let me touch it.

2) Fast forward to early middle school, Ultima VII on an NEC desktop, 90s. That game was great but also a pain in the ass. Had to make a startup floppy disk to help with memory allocation and something else. Learned DOS things. For some reason the disk wouldn't work from one day to the next so would have to reconfigure it frequently. Also learned the hard way not to fork too much with autoexec.bat during this period.

Never give up >.<

Today was all about dynamic memory allocation. I spent my whole day researching and learning this topic. I had watched couple of videos before I got to bed. Just a while ago I had a dream where Bucky Roberts from thenewboston and David J Malan were instructing me. Wow, such a nice dream.

!dev

So I found out that
A) there's no Ham radio bandwidth
B) no Ham radio community
C) that Ham radio is technically illegal
D) but "easily could be made legal
And was considering applying for bandwidth allocation however, the way that applying works, implies a single studio, with equipment costs/budget and the likes.

Have any of you ever played with ham radio?

Since most of you are working in IT , Communication and related fields, what advice can you give to a student like me who has just began studying Computer Science Engineering ...I mean how should I began, what to do next and get myself placed in a good company.

Talking about myself I have started learning C language and have learnt about basics, pointers, memory allocation, not yet started with data structures and algorithms

I have just done HTML and basic CSS , have understanding of MySQL and know a little bit about flask and Jinja framework in python.

If you could share your experiences, like what you felt at this stage what you do and how you do....how you got placed...what should I do different to cope with the growing competition....

Look I know this place is not for this bullshit but.... my seniors are egocentric bastards, my batchmates don't give a shit about CS , and being a student of tier-3 state government college in India, professors don't care......so I really appreciate if you guys can come forward, and especially Indian guys.

Didn't know maps api integration...
Didn't know markers allocation..
Didn't know geolocation..
JavaScript llbit..
Still implemented...
Love you google..stackoverflow..:-p

!rant That feeling you get when you run through your code perfectly after fixing the memory de/allocation :D So rewarding!

I have a personal opinion and correct me if I'm wrong
Why does a programmer need to learn behind the scenes stuff (memory allocation).
I know it helps to understand the concepts better.
Why would I learn how the engine of a car works in order to drive a car ?.
And the only task is required from you to drive a car.
And literally you can code without knowing any of these stuff and since companies only need clean and efficient code.
Will it be really helpful to enhance your coding skills if you know behind the scenes stuff ?

Just realized a member function pointer can be a template parameter as non-type, gonna try to use it do no dynamic memory allocation trick with std::function.

In my latest interview. It's the first in a overly morose process that includes many.

Me: So, about the scope of responsibilities...
Interviewer: <translated from fart noises> "we're a dynamic company"
<translated again> do any shit some big headed brass asks of you

Me: it involves many meetings?
Interviewer: <dismissive fart noises>

Me: Is it for an open field project or an ongoing structure?
Interviewer: We have many ongoing projects, and you allocation may be changed dynamically <so, fart noises>

Me: about the salary...
Interviewer: <Extra-stinky-fart noises>

...
It went on for an hour, never an straight answer. Not even for the name of the company.
...

Me: Have you noticed that, even that you are interviewing me, I'm the one asking all the questions?
Interviewer: <actual fart> yes, you really seem to have the knack for it!
Me: ...
Interviewer: so, any more questions?
Me: Yes. Are you flammable? <actual quote>

Over the weekend, I made the move to use a flash as a repository (don't need no wires to repo!). Felt that needing 12 MB to store less than 2 MB was a little bit high.
So I figured "simple fix, I'll just reformat the drive from 32Kb allocation to something less, like 4Kb".
After 30 seconds of a single copy/ paste, the transfer was complete. Checking the size... accidently clicked "4096 kilobytes" instead of "4096 bytes".
