Search - "memory management"
Microsoft support: "Your antivirus software is causing problems with the memory management."
Me: "I use Windows defender"
Microsoft support: "Oh..."
Interview with a candidate. He calls himself "C++ expert" on his resume. I think: "oh, great, I love C++ too, we will have an interesting conversation!"
Me: let's start with an easy one, what is 'nullptr'?
Him: (...some undecipherable sequence of words that didn't make any sense...)
In my mind: mh, probably I didn't understand right. Let's try again with something simple and more generic
Me: can you tell me about memory management in C++?
Him: you create objects on the stack with the 'new' keyword and they get automatically released when no other object references them
In my mind: wtf is this guy talking about? Is he confusing C++ with Java? Does he really know C++? Let's make him write some code, just to be sure
Me: can you write a program that prints numbers from 1 to 10?
Ten minutes and twenty mistakes later...
Me: okay, so what is this <int> here in angle brackets? What is a template?
Him: no idea
Me: you wrote 'cout', why sometimes do I see 'std::cout' instead? What is 'std'?
Answer: no idea, never heard of 'std'
I think: on his resume he also said he is a Java expert. Let's see if he knows the difference between the two. He *must* have noticed that one is byte-compiled and the other one is compiled to native code! Otherwise, how does he run his code? He must answer this question correctly:
Me: what is the difference between Java and C++? One has a Virtual Machine, what about the other?
Him: Java has the Java Virtual Machine
Me: yes, and C++?
Him: I guess C++ has a virtual machine too. The C++ Virtual Machine
Me (exhausted): okay, I don't have any other questions, we will let you know
And this is the story of how I got scared of interviews29
A university that teaches students
C++ without teaching an understanding of memory management is pointerless.6
Anyone looking for something interesting to do???
Step 1) understand how basic circuitry works on a bread board nothing too fancy. ( Implement NAND, AND, ADDER, SUBTRACTOR)
Step 2) learn about microprocessors and how OS works
Step 3) learn assembly
Step 4)write a basic assembler and understand how loaders and linkers works !
Step 5) write a kernel with very basic features like memory management and process management and some drivers for IO
Step 5) write an emulator for some simple systems .! ex chip-8.
Step 6) read about compiler theory and automata
Step 7) write a basic Python interpreter that compiles (not interpreter) to native assembly.
Step 8) implement TCP stack .
Step 9) learn as much as u can about complexity measurement ), data structures and algorithms using C or C++ it's very important ( familiarity with pointers and thus computer memory )
Step 10) learn any high level language of choice like Python or Ruby.
Step 11) stop debating over tabs vs spaces , emacs vs vim , angular vs vue, php vs Python , OOps vs procedular vs functional ( just know about all of them and when to use but don't fucking debate over which one is superior )..
Step 12) live happily and be healthy.31
Please Java and all java shit, take more memory I don't need it -_-
16GB doesn't seem to be enough to have a VM and Android Studio Open but it is more than enough to have
1. Visual Studio
2. SQL Server Management Studio
5. Visual Studio code
Fuck. This. Shit!20
Not just another Windows rant:
*Disclaimer* : I'm a full time Linux user for dev work having switched from Windows a couple of years ago. Only open Windows for Photoshop (or games) or when I fuck up my Linux install (Arch user) because I get too adventurous (don't we all)
I have hated Windows 10 from day 1 for being a rebel. Automatic updates and generally so many bugs (specially the 100% disk usage on boot for idk how long) really sucked.
It's got ads now and it's generally much slower than probably a Windows 8 install..
The pathetic memory management and the overall slower interface really ticks me off. I'm trying to work and get access to web services and all I get is hangups.
Chrome is my go-to browser for everything and the experience is sub par. We all know it gobbles up RAM but even more on Windows.
My Linux install on the same computer flies with a heavy project open in Android Studio, 25+ tabs in Chrome and a 1080p video playing in the background.
Up until the creators update, UI bugs were a common sight. Things would just stop working if you clicked them multiple times.
But you know what I'm tired of more?
The ignorant pricks who bash it for being Windows. This OS isn't bad. Sure it's not Linux or MacOS but it stands strong.
You are just bashing it because it's not developer friendly and it's not. It never advertises itself like that.
It's a full fledged OS for everyone. It's not dev friendly but you can make it as much as possible but you're lazy.
People do use Windows to code. If you don't know that, you're ignorant. They also make a living by using Windows all day. How bout tha?
But it tries to make you feel comfortable with the recent bash integration and the plethora of tools that Microsoft builds.
IIS may not be Apache or Nginx but it gets the job done.
Azure uses Windows and it's one of best web services out there. It's freaking amazing with dead simple docs to get up and running with a web app in 10 minutes.
I saw many rants against VS but you know it's one of the best IDEs out there and it runs the best on Windows (for me, at least).
I'm pissed at you - you blind hater you.
Research and appreciate the things good qualities in something instead of trying to be the cool but ignorant dev who codes with Linux/Mac but doesn't know shit about the advantages they offer.24
Soooo I think I have finally come to the point that I may have to create a YouTube channel, to teach software engineering from the ground up... and teach it the way the universities and everyone else should be teaching it, so that they have a solid foundation.... throwing hello world, and loops and variables at folks out of the box without any of the environment context or low level embedded register, even logic gate understanding
That lack of understanding is why, soooo many college students and younger folks, are actually pretty shitty engineers. Everything is high level languages and theoretical concepts to them. Nothing practical, that’s why there’s sooo many python and java developers that can’t for the life of them understand memory management, low level hardware interfacing etc, because the colleges don’t teach it the way it use to be taught.
I seriously fear 30 years from now or sooner when there are few embedded engineers only left till retirement, as without those folks the whole pyramid of electronics falls to pieces.
Java, C#, python, all that shit don’t run on the bare metal... there’s this magical layer of C, and assembler that does all the work just so folks can abstract their thoughts.
Either 1 of two situations will happen.. price of electronics will rise because the embedded guys are few and far between therefore salaries skyrocket... OR everything starts running shit like java on the metal, where there are a over abundance of developers, their salaries will be low because there are soo many but the processing power, space, and energy needed to run java natively causes electronics cost to increase
but regardless 30 years from now if those script kiddies are building everything I fear it cuz there’s gonna be memory leaks, and overflow issues everywhere.. shit be blowing up more than 4th of July.. lol
Soooo in effort to prevent that and keep the embedded engineers up, or atleast properly educate the script kiddies, I’m gonna make that YouTube channel.. 1 maybe 2 videos a week, 1-2 hours sessions each.. starting at the fucken ground and building up.43
I'll use this topic to segue into a related (lonely) story befitting my mood these past weeks.
This is entire story going to sound egotistical, especially this next part, but it's really not. (At least I don't think so?)
As I'm almost entirely self-taught, having another dev giving me good advice would have been nice. I've only known / worked with a few people who were better devs than I, and rarely ever received good advice from them.
One of those better devs was my first computer science teacher. Looking back, he was pretty average, but he held us to high standards and gave good advice. The two that really stuck with me were: 1) "save every time you've done something you don't want to redo," and 2) "printf is your best debugging friend; add it everywhere there's something you want to watch." Probably the best and most helpful advice I've ever received 😊
I've seen other people here posting advice like "never hardcode" or "modularity keeps your code clean" -- I had to discover these pretty simple concepts entirely on my own. School (and later college) were filled with terrible teachers and worse students, and so were almost entirely useless for learning anything new.
The only decent dev I knew had brilliant ideas (genetic algorithms, sandboxing, ...) before they were widely used, but could rarely implement them well because he was generally an idiot. (Idiot sevant, I think? Definitely the idiot part.) I couldn't stand him. Completely bypassing a ridiculously long story, I helped him on a project to build his own OS from scratch; we made very impressive progress, even to this day. Custom bootloader, hardware interfacing, memory management, (semi) sandboxed processes, gui, example programs ...; we were in highschool. I'm still surprised and impressed with what we accomplished.
But besides him, almost every other dev I met was mediocre. Even outside of school, I went so many years without having another competent dev to work with. I went through various jobs helping other dev(s) on their projects (or rewriting them), learning new languages/frameworks almost every time: php, pascal, perl, zend, js, vb, rails, node, .... I learned new concepts occasionally (which was wonderful) but overall it was just tedious and never paid well because I was too young to be taken seriously (and female, further exacerbating it). On the bright side, it didn't dwindle my love for coding, and I usually spent my evenings playing with projects of my own.
The second dev (and one one of the best I've ever met) went by Novo. His approach to a game engine reminded me of General Relativity: Everything was modular, had a rich inheritance tree, and could receive user input at any point along said tree. A user could attach their view/control to any object. (Computer control methods could be attached in this way as well.) UI would obviously change depending on how the user could interact and the number of objects; admins could view/monitor any of these. Almost every object / class of object could talk to almost everything else. It was beautiful. I learned so much from his designs. (Honestly, I don't remember the code at all, and that saddens me.) There were other things, too, but that one amazed me the most.
I havent met anyone like him ever again.
Anyway, I don't know if I can really answer this week's question. I definitely received some good advice while initially learning, but past that it's all been through discovering things on my own.
It's been lonely. ☹2
Why is it so important to some people to claim that "HTML and CSS are not programming languages"? I get it, you're a REAL programmer working with arrays, maybe tuples, objects and possibly direct memory management. Who the fuck has a right to call themselves a programmer for writing some brain dead markup or poorly designed selectors, right? Who fucking cares for semantic tags or nested selectors?
Just think for a few seconds about when you were taking your first baby steps to becoming the GOD ROCKING MEMORY HANDLER THAT WRITES _REAL_ CODE that you are today, and how good it felt to be able to create something that appeared on your screen. It felt pretty awesome, yeah?
Now imagine if someone much more experienced than you told you "You're not a real programmer, that is not real programming. You should see what I do, I do real programming".
I think you get it. Why spend your energy spreading bad vibes when you could spend it on something more productive. Like reading up on the new CSS4 specs ;)18
A year ago, in the second programming course in uni, we had an assignment about making a linked list. It was nice, as I learnt how they are made. But then we had another, then a lab, and after that other 3 assignments adding functionalities to our list and improving it. It was horrible, but it was finally over.
The problem is that the following semester, the first assignment of the operating systems course was about making a list. The first assignment of the programmimg course made us implement a list too, to practice polymorphism. We had lists also for the last assignments for those two courses (they were about heaps and custom memory management respectively).
At this point I was completely fed up with lists. That brings us to the present, and guess what we are having for the first assignment of the algortihms & data structures course... Yeah. I hate linked lists6
I'm fairly sure that even if I were to run Windows 10 on a machine with double ECC, it'd still BSOD because of poor memory management. Because why on Earth would Microsoft support such a basic, essential thing properly, hmm?!!
Oh and let's add HDMI to the existing list of ACPI and USB. How difficult can it possibly be to support those basic, most standardized fucking hardware protocols? Pretty fucking insanely hard apparently!!!3
A couple days ago, I went through the most embarrassing interview ever. It was a startup into both hardware and software merged over image processing. I really wanted it. Really really did. It was telephonic, and involved a little bit coding over docs. In the one hour we talked over the phone, he asked me about 30 questions. I hadn't even heard of the words he said! Ive never delved into compilers, lower level things, and memory management. I could answer about 5 questions- including the tell me about yourself question.
So thats about 25 ways I came up with of saying "I don't know" in a span of 60 minutes.3
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.5
It has been a loooong time since i have had awesome programming day like today, i've been doing earth simulator kind of game for mobile and lots of its core mechanics are starting to take shape. Still long way to go but it feels great! Days like these remind me why i started programming. I will have to deal with memory management because there will be lots of shit happening on screen not yet sure how to deal with that in corona sdk. Sorry for good feels.11
I dive in head first.
Some existing program annoys me, so I get this itch to write a selfhosted Spotify in Go, or a conky with 3D graphics in Rust.
I check the homepage of the language, download the tools, check which IDE is great for it.
Then I just start writing code, following the error corrections thrown by the IDE, doing web searches for all errors. Then when I run into a wall, I might check the reference docs or a udemy course.
Often I don't finish the project, because time is limited and I still have 4 million other things to do and learn, but at least I've learned a new language/tech.
Con: For tech which uses unique paradigms like Rust's memory management or Go's Goroutines, it can be frustrating to bash away at a problem using old assumptions.
Pro: By having a real demand for a product with requirements instead of a hello world or todo app, it's much easier to stay motivated, and you learn beyond what courses would teach you.5
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.10
A friend came to me whether i want to do a project on c++(someone asked him to find a c++ guy).
Me needing money didn’t refuse. Even though i am a Java developer with 0 skills on c++, but wanted to give it a try.
So project started, and it was about a plugin for rhinoceros app(3d graphics app).
The plugin was simple, had some views and some services to upload a file into s3 and some api calls, not something complex..
So i ended up working on the project together with my friend(web dev).
So long story short, we had a lot of issues, but considering we both had no knowledge on c++, we were really lucky to finish the product almost on time(3 days after).
Did no memory management even though i’ve read that we have to do that by our selfs and that c++ doesn’t have garbage collector.
But the plugin worked great even without garbage collector.
Had a lot issues with string manipulation, which almost drive me crazy.
PS: did a post here before taking the project, to ask whether it is a good idea to take the project or not, had some positive and some negative replies, but i deleted the post since i thought i was breaking the NDA i signed 😂😂
PS2: just finished OCAJP 8 last week with a great score😃6
Professors today in colleges don't know...
1. the proper denominations of outputs of basic shell commands like "ls -l", "cat", "cal" (pronounces linux as laynux)
2. how memory management works
3. how process scheduling actually takes place and not in the outdated bookish way.
4. how to compile a package from scratch and including digital signatures
5. cannot read a man page properly, yet come to take OS labs.
6. how to mount a different hardware
7. how to check kernel build rules, forget about compiling a custom kernel.
Yet we are expecting the engineers who are churned out of colleges to be NEXT GEN ?!
It is not entirely because of syllabus, its also because of professors who had not updated their knowledge since they got a job. Therefore they cannot impart proper basics on students.
If you want things to change, train students directly in the industry with versions of these professors UPDATED.7
I started writing code at a young age, nodding games, building websites, modifying hex files, hacking etc... I started my career off tho in highschool writing embedded code for a local medical robotics company, and also got tasked with building the mobile app to control these robots and use them for diagnostics, etc.... this was before the App bubble, before there was app degree and that bullshit.. anyway graduated highschool, went to college to get a comp sci degree.
Wanted to teach for the university and research AI...
well I dropped out of college after 3 years, cuz I spent more time at work than in class. (I was a software consultant) in the auto industry in Detroit. I wasn’t learning anything I didn’t already know or could learn from books or a quick google search.
I also didn’t like the approach professors and the department taught software... way none of the kids had a good foundation of what the fuck they were doing... and everyone relied on the god damn IDEs... so I said fuck it and dropped out after getting in plenty of arguments with the professors and department leads.
I probably should have choose CE .. but whatever CS imo still needs a solid CE/EE foundation without it, 30 years from now I fear what will become of the industry of electronics... when all current gen folks are retired and nobody to write the embedded code, that literally ALLLLL consumer electronics runs on. Newer generations don’t understand pointers, proper memory management etc.
So I combined both passion AI and knowledge of software in general and embedded software, and been working on my career in the auto industry without a degree, never looked back.2
My first real exposure to a PC was when my father and me built one for myself. Y'know, some AMD Athlon 64, some MSI board, 2 GB of RAM, an NVIDIA 8600 GT, everything was nice.
I never put malware on that thing even though I heavily used it for things like games, I was really cautious with that even when I was like 6 years old (but my father once accidentally did, he killed it by damaging the filesystem on the harddrive which, funny enough, only took the malware with it)
I still have that PC, but it now has weird issues with memory management ;-;
Trying to develop Java applications in Windows...
sed s/Java applications/anything/g
'sed' is not recognized as internal or external command, operable program or batch file
When I was about 10, I used to read these magazines with code listings for programs, and the only things I really understood were these text adventures that I imagined to be of Zork-like quality (gasp!). In reality, it was more like the choose-your-own adventure books of the time (which were actually pretty cool, and had pretty tight memory management). At one time, on a vacation somewhere in the eighties, I got tired of playing in the river with my friends and instead opted to continue writing lines of BASIC in a little paper notebook, inside my parents' car (at 34 degrees C), trying to perfect a storyline about my little brother and his pet dog he got for his most recent birthday, fighting the cat empire etcetera etcetera. Weird looks, good times.
Windows rant incoming!
For fucks sake! I think Windows have asked me 117 times if I want to update now. The answer is still fucking no!
And I don't care how much of a security improvement it might be, when your shitty update causes a Memory Management error.
So fuck off, stop minimising my game while I play and go fix your shitty update first!
Fuck you Microsoft, fuck your QA team and while I'm at it, I want to say fuck you to all versions of Windows Server as well!7
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
So another story about college and stupid team assignments that I have to be responsible for dealing with.
So we had an assignment in operating systems 1 course, it was about memory management and we are a team of 3. Then came the time when we should discuss this assignment with the TA and that day I had to stay all night finishing a project in software engineering (literally giving us a description of a big project because that's what the course teaches And I had to finish it in one all nighter alone because my teammates just gave up).
When the discussion time came I was really tired and then the TA asks me something really simple and I say it but then she tells me that I'm wrong so I wondered a bit and then said no what I said was right! She then asks my teammate (who we are supposed to be good friends) "did he say the right thing?" And his answer is a definitive "NO he's wrong" and then he starts to say the right answer which I swear I said the same but in a different way so I start to say again that I was right and say that I said that just a different way and she took that as an insult and said that I'm shouting at her and being disrespectful to her.
When we finished I asked my friend if he heard me say it wrong and he said "I'm sorry but I didn't even hear what you said and I was afraid" WHAT THE FUCK, he just said that I was wrong to please her and make her feel like she is right and I had to be the wrong one even though I said it right but NOoo her pride is more important
All this was last semester and the second semester just started today and I go into operating system 2 and guess what? The TA got her doctorate and is now the professor for OS 2 when she doesn't even understand anything.
Really FUCK the academic system it feels like it is a grind more than actually gaining mastery of a subject.2
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.1
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 BRAH4
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 everything6
Today I watched "the birth and death of js":
Here Gary Bernhardt talks about compiling executables to asm.js and about running the compiled files using a js interpreter that can be included in the kernel.
Eventually, some responsibility can be moved from the kernel to this interpreter, responsibility like virtual memory and trap management.
This speech aims to be fun, so not everything should be taken seriously...
...this trick seems to be a nice idea, and projects like Node OS work likewise.
So now, would you even consider this? Or is it just something that will be nothing more than craziness of a mad man?1
Identifying when to start a project over because it has gotten out of hand with workarounds and memory management issues.
When a DevOps engineer finds a fault with memory leaks on the application/software that crashes services and management responds with "Lets Scale The Application".5
I'm thinking of designing a programming language.
I want it to have easy to read syntax like python. Inheritance and interfaces like java. More advanced concepts like pointers and memory management like c++.
I was originally going to write my own compiler but I figured it's not worth reinventing the wheel. So the current plan is to basically just create a parser that turns a source file into c++ code and then that is compiled with g++. The only problem I can think of with that is catching runtime errors.
How does this language sound?
My purpose is to have a language that is as easy to read as python but with the speed of a compiled program and the ability to use it for embedded projects. I feel like reading larger C++ projects can be quite time consuming. So I figure the trade off of taking a little longer to write the code to make it more obvious what is going on is better than having a lot of syntax that can be tough to walk though the logic of (I find this often with c and c++, not like I don't figure it out but It definitely takes longer than it does to read and understand python)4
Things I say to my clients when I know that a reboot is required to fix their issue but I don't have enough evidence to prove it to them :
"... On any computing platform, we noted that the only solution to infinite loops (and similar behaviors) under cooperative preemption is to reboot the machine. While you may scoff at this hack, researchers have shown that reboot (or in general, starting over some piece of software) can be a hugely useful tool in building robust systems.
Specifically, reboot is useful because it moves software back to a known and likely more tested state. Reboots also reclaim stale or leaked resources (e.g., memory) which may otherwise be hard to handle. Finally, reboots are easy to automate. For all of these reasons, it is not uncommon in large-scale cluster Internet services for system management software to periodically reboot sets of machines in order to reset them and thus obtain the advantages listed above.
Thus, when you indeed perform a reboot, you are not just enacting some ugly hack. Rather, you are using a time-tested approach to improving the behavior of a computer system."
Memory debugging iOS probably makes me more anxious and stressed out than anything. I have put 11
hours into attempting to figure out this crash, but still no progress. It's like I can feel management breathing down my neck to get it done asap. You ever get so stressed out while trying to figure something out at work?3
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
Sydochen has posted a rant where he is nt really sure why people hate Java, and I decided to publicly post my explanation of this phenomenon, please, from my point of view.
So there is this quite large domain, on which one or two academical studies are built, such as business informatics and applied system engineering which I find extremely interesting and fun, that is called, ironically, SAD. And then there are videos on youtube, by programmers who just can't settle the fuck down. Those videos I am talking about are rants about OOP in general, which, as we all know, is a huge part of studies in the aforementioned domain. What these people are even talking about?
Absolutely obvious, there is no sense in making a software in a linear pattern. Since Bikelsoft has conveniently patched consumers up with GUI based software, the core concept of which is EDP (event driven programming or alternatively, at least OS events queue-ing), the completely functional, linear approach in such environment does not make much sense in terms of the maintainability of the software. Uhm, raise your hand if you ever tried to linearly build a complex GUI system in a single function call on GTK, which does allow you to disregard any responsibility separation pattern of SAD, such as long loved MVC...
Additionally, OOP is mandatory in business because it does allow us to mount abstraction levels and encapsulate actual dataflow behind them, which, of course, lowers the costs of the development.
What happy programmers are talking about usually is the complexity of the task of doing the OOP right in the sense of an overflow of straight composition classes (that do nothing but forward data from lower to upper abstraction levels and vice versa) and the situation of responsibility chain break (this is when a class from lower level directly!! notifies a class of a higher level about something ignoring the fact that there is a chain of other classes between them). And that's it. These guys also do vouch for functional programming, and it's a completely different argument, and there is no reason not to do it in algorithmical, implementational part of the project, of course, but yeah...
So where does Java kick in you think?
Well, guess what language popularized programming in general and OOP in particular. Java is doing a lot of things in a modern way. Of course, if it's 1995 outside *lenny face*. Yeah, fuck AOT, fuck memory management responsibility, all to the maximum towards solving the real applicative tasks.
Have you ever tried to learn to apply Text Watchers in Android with Java? Then you know about inline overloading and inline abstract class implementation. This is not right. This reduces readability and reusability.
Have you ever used Volley on Android? Newbies to Android programming surely should have. Quite verbose boilerplate in google docs, huh?
Have you seen intents? The Android API is, little said, messy with all the support libs and Context class ancestors. Remember how many times the language has helped you to properly orient in all of this hierarchy, when overloading method declaration requires you to use 2 lines instead of 1. Too verbose, too hesitant, distracting - that's what the lang and the api is. Fucking toString() is hilarious. Reference comparison is unintuitive. Obviously poor practices are not banned. Ancient tools. Import hell. Slow evolution.
C# has ripped Java off like an utter cunt, yet it's a piece of cake to maintain a solid patternization and structure, and keep your code clean and readable. Yet, Cs6 already was okay featuring optionally nullable fields and safe optional dereferencing, while we get finally get lambda expressions in J8, in 20-fucking-14.
Java did good back then, but when we joke about dumb indian developers, they are coding it in Java. So yeah.
To sum up, it's easy to make code unreadable with Java, and Java is a tool with which developers usually disregard the patterns of SAD.
TLDR: need advice about CS degree, worth it or not?
Already for some time I have been thinking about getting back to studying and finally for once get that fucking bachelor degree.
I have tried to study already 2 times. Both had quit not even after single year of studies.
First time was CS in my origin country, quality was really bad, so I quit during first semester.
Second time I moved to the Netherlands to study AI. Liked it a lot, but it was quite too much for me, I wasn’t ready for commitment to learn all parts of brains, all neurological diseases and stuff like that. Quit during 2nd semester.
Also, I have been in industry for 4 years now, working as php web developer. I am 22. Have a well paid job.
I want to study CS again, with specialization of cyber security, but in NL (same uni I studied AI, so I expect good quality). Also, as I already know programming, and a lot of other cs stuff, I expect I will need invest less time, and so I can also work in some company part time or even full time.
So in my consideration following are pros and cons of my this decision:
- I will be forced to learn basic cs stuff like memory management, how processes work in low level... And so I will be able to write better quality software.
- I will satisfy my parents wishes and also will be only one in my family with bachelor degree and I want my parents to be proud of me.
- I will meet like minded people, new friends, connections and will have higher probability to find a girlfriend.
- After getting degree, I will have possibility to work for government institutions, but I think this one should be in cons.
- No serving in military during study period (mandatory in my country for 9 months if you were called. till age 26 only)
- minus 9k euros
- minus 3 years of my free, undisciplined life
- a lot of sleepless nights
- possibility of getting depressed and questioning the meaning of life (but working in industry has the same effect)
Well, can’t actually think of something else.
I would like to hear your opinions on this, especially of people who had positive study experience. Thanks.6
About to start writing a report for my programming languages course, I’m writing it over GoLang, If anybody has any good resources for any information on Go, let me know!
The report extends into the history, paradigms, features, memory management system, and anything else I can possibly find on this language. I can find some pretty decent references on the footer of Wikipedia, but I wanted to see if anybody who actually used Go had anything they’d like to share.
I have a love hate relationship with C honestly. I hate that you have to do so much overhead management and control of all of your pointers and arrays and manually handle memory allocation and management, but on the other hand it's pretty cool to work that low / close to the machine code and the programs run lightning quick. Pros and cons, I guess. Would've been interesting to be around in the early days..1
Debugging a WCF app and could for the love of it not get its main window up. Then I realized it was freaking Photoshop that placed itself on top of it. PS is great for editing images, but has useless management of windows and memory, at least on Windows, originally developed for Mac as it is.
Not a rant but just curious to see what mobile OS do all you devs on devRant use?
I recently moved from Android to iOS. Doing so has made me realise how much I loved using Android but due to its inherent stuttery lag, inferior standby time and memory management, I will be staying with iOS for now.
What are your reasons on using the mobile OS that you are using now?7
