Programming / Re: When Do I Use Calloc() And Malloc() In C Language? by valzey(m): 7:24pm On Sep 13, 2020 |
logicDcoder: Malloc does not set the bytes it allocates to zero while calloc does. That is their difference. Other than this, they are the same, they are all contiguous blocks I think. If you allocate sizeof(char) * 5, and you will use all of the bytes, malloc is OK, if you may not use up all the bytes, then use calloc so that the unused parts will be zero. |

codeigniter:Yh, sometimes customers overlook security, but it's important and it costs money. At times customers don't even have plan, talk less of detailed plan and you can't hope to get returns on investment without a plan. Next there's advertisement and marketing. Finally, there's no true business without plan. Even scam artists plan. If you have a plan, then it can be achieved. You can't leave the business plan on the head of the developer, he's just a contractor. You own the business. For people without plan, I ignore or collect good money first before working because their job usually had no scope and no end. You stop when you're tired. 2 Likes |
Programming / Re: When Do I Use Calloc() And Malloc() In C Language? by valzey(m): 1:50pm On Sep 11, 2020 |
I think using malloc, the block of memory you have is uninitialized, i.e: whatever data in that space previously will remain there. while in calloc, it is initialized to zero. Calloc is like a combination of two functions Malloc and another used to initialize to zero. Use malloc if you'll use all the blocks allocated and use calloc if you'll use some of the blocks allocated. |
Programming / Re: Please Help, Its Urgent by valzey(m): 11:08am On Sep 11, 2020 |
Online doesn't only mean YouTube, there's Udemy, Pluralsight, Coursera... etc. And they're good and actual courses not tutorials . But physical tutoring also has its advantages, it depends on the person to be trained. No need for sharp criticism. Just make your own suggestions. I'm not in Asaba so I can't recommend since he explicitly said he doesn't want online. |

Programming / Re: Shine Your Eye - Use This Guide To Learn How To Buy A Good Laptop For Coding by valzey(m): 10:52am On Sep 11, 2020 |
You totally have reason to use Linux, but most programmers don't and we can't advise budding programmers to get Linux because they will spend productive time trying to figure out how to get this or that working. I use Linux rarely so it's place is in a VM until WSL fully matures. If Linux is so important to you, you should use it as your OS or dual boot it not in a VM. And I left C++ for C# and I'm a happy guy now. I remember then when trying to port my C++ program to Windows, some headers then were not available on windows GCC. I gave up. 1 Like |

Programming / Re: Shine Your Eye - Use This Guide To Learn How To Buy A Good Laptop For Coding by valzey(m): 8:48am On Sep 11, 2020 |
No need for POSIX and ELF binary executables here, the answer is simple. With windows, every software is download -> click to run. But Linux is a pain, apt-this, apt-that, purge, upgrade.... etc. Who needs that? you can have Linux on a VM if you need some features but trust me, OP doesn't need any of the features. Also free GNU doesn't always mean better. It's just a licensing like MIT etc. Rather than Linux use mac though they are equally empty to me but mac os is way more reliable , if you want ELF. Then speaking of programming, I cannot see advantages of Linux over Windows, even docker can be used on Windows. Then talk about native gaming, incomparable. I don't aim to compare OSes, rather to show that in this context, comparing them is pointless. |

yusman14:U means ultra-low TDP/power. They are supposed to be more power efficient than their H and M counterparts, delivering better battery life but at the cost of performance. The laptop's okay overall, just upgrade the RAM to at least 8gb and you'll be fine. But I've not seen that processor before. Not even on Intel website. You should check the laptop spec online to see if it matches yours. 1 Like |
Programming / Re: How CI/CD Helps In Saving Up To 20% Of Time In Mobile App Development? by valzey(m): 8:08am On Sep 02, 2020 |
Actually CI/CD is awesome. I use Azure DevOps for that. One case I use it is during my docker dev. I run into issues occasionally when building docker images on my laptop after adding new features to previous version. So I simply wrote my build and deploy pipeline. Now whenever I push to repository, it automatically builds the image and deploys to registry and sends me an email confirming if successful or not, all with Microsoft server without my cpu or ram bothered. It's really awesome. |

Programming / Re: Good Pharmaceutical Inventory Software But No Clients To Purchase It by valzey(m): 2:16pm On Aug 16, 2020 |
Donpre: You could also give 5 pharmacies free trial for limited period after explaining to them the value of your product. If they like it, they pay for continuous use, if they don't like it, they tell you why and you work on improving it. Then use them as reference to others and put a fee. It would have been easier to market an existing product that is already tested and trusted. 2 Likes |
Programming / Re: Rant On Operating System Stuff. by valzey(m): 5:54pm On Aug 15, 2020 |
SegFault:It's just that I don't have any reason to go there. It was excitement and adventure then, now I'm older. I need a simple life and my games. I even looked the hackintosh direction, dualbooted mac os yosemite, el capitan and Sierra on my laptop with clover bootloader. Found no value in them and wiped them. Though I learnt how mac operates during that time. C/C++ binaries I compiled using gcc and cmake on mac worked directly on Linux. |
Programming / Re: Rant On Operating System Stuff. by valzey(m): 3:05pm On Aug 15, 2020 |
I acknowledge that Linux is useful but I cannot put it in my personal computer as a daily driver, not even dual boot. If I have any use for it, I use a vm since wsl is far from perfect yet. Every problem you encounter in your installation will definitely be a pain. You'll be forced to learn a whole lot of stuff just to solve the problem. From UEFI/Bios - > boot order -> Grub bootloader -> kernel headers - > apt-get update && upgrade - > dkms driver loading - > Gnome/Xfce -> ntfs-3g... It never truly ends. Restart does not solve problems there. I'm just a simple guy who wants to live a simple life without unnecessary complications. |
Programming / Jack Of All Trades - The Dev Struggle by valzey(m): 4:18pm On Aug 14, 2020 |
I went through a post of a person on nairaland introducing himself to potential clients and looking at his skillset I was tempted to ask him Are these platforms you've tried or platforms you know? - because they were basically the whole visual studio workload. When I'm looking at too many platforms, I improve slower due to lack of focus. It's not easy for developers who haven't settled in a software development niche. The person mentioned Web dev, Mobile dev, Desktop applications each with about 5 technologies under.... It must have been hard for such a person looking for direction. This is what Nigerian devs suffer, due to difficulties getting jobs, we end up as Jack of all trades, Master of none. We scratch the surface of a language or framework and run off to the next one just to remain employable. Some of us even have different resumes for each niche. But how well does it workout. We are forced to ignore the theory of the language or platform and focus on doing a project no matter how simple. Then we go on to fail in the theoretical interview. I wonder how many JavaScript devs can tackle those strange interviews. Everyone wants to learn one and master it but the question is Which one. I wish those successful in this field share their experience with those who are still confused. God Help Us 2 Likes 1 Share |

Programming / Re: I Have Switched To Vim As My Primary Editor, You Should Too by valzey(m): 4:26am On Jul 03, 2020 |
Not enough reasons bro. I can't trade vscode for any other general editor, especially not vim. Giving up intellisense, debug tools, version control, extensions....etc just to feel that I'm a geek. Definitely not. Moreover vscode has terminal too. Your reasons ain't convincing enough especially for those with large projects, collaboration...etc. I began my programming career with gedit which was good for small programs or making changes to a project but I can't use it to begin a project. I put vim in same category. Soon your excitement will die and you'll go back to your previous editor. 10 Likes |
