    Likwid reacted to QuantumRand in Seeking to code like a pro using VS.   
    You recently asked about getting AVX instructions to work in your code. I explained the problem you were running into, and you got upset that I didn't just write the code for you. Even when I took the time to setup an x86 environment (since I develop on ARM64) and then wrote some example code for you, you completely lost interest and had moved on to asking a question about optimizing memory. Several people tried to explain that your question wasn't practical without a specific use-case in mind. You again ignored those responses, lost interest, and then moved on to asking about variadic functions, I assume because you were under the impression that calling functions as a list of function pointers resulted in less program memory (it doesn't). Again, we tried to explain to you that what you were trying to do wasn't practical, and I even gave you example code demonstrating what you were trying to achieve. You ignored that example code (maybe you just didn't understand it?) and then moved on to your next unrelated question.
     
    I'm sure others feel similarly that we want to help you with your interest in programming and continue to encourage you to learn, but it's been hard to continue offering you advice when you continue to ignore it.
     
    Stop trying to dig into the esoteric details of C. You're not going to find some magical algorithm that radicalizes the language. Start with the basics. Find a text book and/or online repository of C coding challenges with explanations and solutions.

    I would say, it's important to learn the fundamentals and then things like what IDE etc you are using can come later.
     
    I literally started programming use notepad, not notepad++, but MS notepad.
     
    It didn't have anything fancy, and I had to create bat files to compile my code...but it worked and I learned the fundamentals.
     
    You learn basic ideas that way of how to find issues with your code.  You learn to read compiler errors/error codes and learn what they mean that way (instead of how some kind of spoon feed you these days).
     
    Not saying IDE's are bad, they are great tools, but ultimately you should be able to hop onto other platforms and program with just a bit of learning curve (you learn one IDE you pretty much learn them all...you just need to figure out where the menus etc are).

    Likwid reacted to Avocado Diaboli in Seeking to code like a pro using VS.   
    Well to be fair, you guys have been rather patiently explaining to him pretty much everything he's been asking for. He's been trained to just use ChatGPT to conjure up a bit of code he doesn't fully understand and then goes and asks experienced programmers about it in a misguided attempt to learn programming in the most inefficient manner possible. So far, the results are exactly what he expects: He posits a question and you give him answers. And his behavior when he gets an answer he didn't expect is to raise objections in ways every walking Dunning-Kruger phenomenon does, by second-guessing everything that you write with a degree of dismissiveness and an air of authority that don't befit someone of his experience level. Because a Dunning-Kruger phenomenon is what he is. I've been observing this charade for a while now, how he thinks he can improve upon standard library functions while at the same time barely being able to get a text editor or an IDE running. To be honest, I'd stop responding to his threads entirely until he's proven he can actually write working code, even if it's horrendously ugly and inefficient.
     
    @Gat Pelsinger, you remind me of another forum member we had a while ago, @Wictorian. If either of the two accounts' locations are correct, you're not the same person, but the uncanny ability to ask advanced questions in the wrong way and for the wrong reasons is eerily similar. So in that spirit, I'll pull out the same harsh advice I dished out to Wictorian:

    Stop trying to put the cart before the horse. Don't muck around with reinventing basic functions and trying to improve on those. Don't waste time with premature optimization if you can't even write a complete program. And for fuck's sake, don't try to write a garbage collector in C if you can't even produce a calculator first. In fact, I'd advise you to quit two things immediately: ChatGPT and C. The former for obvious reasons, you're not gonna learn anything by having an LLM produce code snippets or summarize tutorials for you. The latter because you have a tendency to miss the forest for the trees. Learn Python first. Get comfortable with logically breaking down problems into smaller problems with easy ways to implement the solutions. That way, you don't front load your learning, because this will always lead to a brick wall. If you eventually arrive at a project worth coding in C, you'll be ready to adapt that knowledge and have a much easier time. You don't need to peek behind the curtain to know how the CPU deals with the ones and zeroes. Trust that smarter and/or more experienced people have dealt with that for you and focus on actually learning programming concepts. Once you have the experience and notice something that can be done better, you'll be in a more suitable position to actually improve on the basic tools everybody else is using.
     
    Another bit of advice: If you don't know how to do something, you will need to be able to efficiently look up information. The mark of a good programmer isn't to know everything about everything all the time. It's the ability to break down problems and if you have areas where knowledge is spotty or lacking, you need to be able to find information autonomously to fill those gaps. This is not done by asking ChatGPT or forums, nota bene. Read the documentation. If you still can't figure something out, at least show what work you did when asking questions. People aren't your servants who tell you stuff you could figure out yourself with a couple of minutes of Googling yourself. Telling people what you did saves them the trouble of telling you what you already know so they can confidently point you in a direction you might have missed or not known about. That's what saves both you and others time and headaches. You're asking people for help, after all. The least you can do is put in the effort to make it easy for them to help you.
     
    And lastly: You really need to drop the obsession with text editors. No text editor in the world is going to make you a better programmer. Coding in Vim or Emacs isn't going to impress anyone. Write with the tools you find most comfortable. The important part isn't the window where you type text. It's the result that text produces. And from what I've seen across all your threads, you haven't produced much. Focus on that.

    Likwid reacted to keean_s in Intel 13th/14th gen how to test for a bad core causing game crashes   
    Here's how you can test your 13th or 14th gen CPU to see if it has a 'bad' core. This will use Windows Subsystem for Linux and a pre-built image of Gentoo to run an intensive compiler task to stress each p-core one at at time. Testing each p-core will take about 1 hour on a 14900k, however in my case the 'bad' cores fail pretty quickly.   Download https://distfiles.gentoo.org/releases/amd64/autobuilds/20240421T170413Z/stage3-amd64-systemd-20240421T170413Z.tar.xz   Open PowerShell with admin permissions, you will need to adjust the paths for your windows login user. On my test machine it's "C:\Users\Admin" replace with yours.   Enable-WindowsOptionalFeature -Online -FeatureName Microsoft-Windows-Subsystem-Linux Enable-WindowsOptionalFeature -Online -FeatureName VirtualMachinePlatform wsl --set-default-version 2 wsl --import gentoo C:\Users\Admin\gentoo C:\Users\Admin\Downloads\stage3-amd64-systemd-20240421T170413Z.tar.xz --version 2 wsl -d gentoo -u root   Then open task manager, switch to details, find "vmmemWSL" and right-click "Set affinity" and uncheck "All Processors", and then check just two CPU at a time, for example CPUs 0 & 1   then in the WSL shell run:   emaint sync -a   To update the package repo. Then to run the test on the currently selected (with set affinity) p-core using three threads:   MAKEOPTS="-j3" emerge -1 gcc   This will fail at some point with an error, core dump, or just terminate the VM if there is a problem with the CPU core, or complete successfully if there is not.   You can try different pairs of CPU in the different p-cores:   0 & 1 2 & 3 4 & 5 6 & 7 8 & 9 10 & 11 12 & 13 14 & 15   to see which p-cores have a problem.   You can prove it is a CPU core problem, and not anything else in the system by running the compile without setting the affinity for comparison.

    well, the 6600xt is noticeably better than the 6600xt. however, it is used, so i'd say that you wait, save up, and get an even better card later. the 6600 should be enough for most games at the moment.

    Well the 3200g will work, but not very well. maybe it was good 4 years ago, but not anymore. maybe save up a bit and get a used 5600g for minimum double the performance. It should be fine though.

    Likwid reacted to CoolJosh3k in Lamptron caught mass selling invalid AIDA64 keys   
    Summary
     As I understand it, Lamptron is mass reselling the AIDA64 software as the core component of their products, but they never actually bought the keys they are “reselling”.
    A discovery that is causing issues for many distributors now they know about it and maybe customers too.
     
    Quotes
    My thoughts
     Based on what was said in the video, it sounds like everyone who has bought and used on of the many Lamptron products could face legal issues if they now learn of this, or simply figured it out on their own.
    I find it very interesting that a company can keep doing such an illegal activity at such a scale for so long, while putting anyone they distribute through at major risk of legal trouble.

    Likwid reacted to OddOod in MSI Tomahawk B450 bios update issues, solid CPU debug/error light, no post   
    Welcome to the forums!
    First, I would like to confirm that you had a cpu cooler on the mobo while it was updating the bios, is that the case?
    Second, try the 3600x. It's possible that the bios update went through and it's just waiting on a new CPU
    Third, it's possible the bios settings are in a weird state. Follow these instructions:

     
    Fourth, it's possible the bios update failed, but is in a recoverable state. Insert the 1600, put your USB stick in the Flash BIOS Port (bottom of the stack closest to the Flash BIOS button) and follow the instructions


     
    Fifth, it's possible I've missed something and you're still safe
    Sixth, it's possible the BIOS update failed in an unrecoverable state and the mobo is bricked

    I would probably ask this question in a community of AI/ML folks that actually do the work you do. They might be able to better guide you towards what parts would be the best use for your money. I wouldn't recommend a prebuilt, and you might not need a 14900KF for what specific purpose you want to use it for. Your usecase might benefit from a cheap processor next to 2 4090s instead, or 2 used 3090s for cheaper. You should probably seek guidance from the type of experts that do exactly what you do, that would probably be a lot more helpful.
