This is impressive man! Keep going, you definitely meant for greater stuff!

Like coupled with Jetbrains eating ram and the complex architecture , I think Flutter is the sanest choice.

My brother, even saner than sanest!

The android emulator is slowing down my PC, can't do anything when it's on.

Even downgraded to Android 8, still same thing.

Anyway around this? I use Hp ProBook 6th gen corei5 4gb ram

Don't use an Android emulator on a 4GB RAM laptop!!! Use your Android device instead

Learn kotlin

For why? I love flutter!!!

By the way, I know Kotlin and I use it sometimes. I just don't like the fact that the compiler (and gradle) is always resource-hungry

nnamdiosu:
Very nice. I'm going over there now.

Please what's the minimum system requirements to install the flutter sdk on a machine. Thanks

Sorry I took this long to reply, but really not much. A Core 2 Duo (which is what I use) is more than sufficient for mobile development. Anything desktop development for flutter will require OpenGL 3. But most systems nowadays will run flutter without issues

Hello guys. I just made a flutter crash course on my YouTube channel that will help you get started with working with flutter in just about an hour.

If you don't know what flutter is, it is a cross-platform UI framework created by Google that helps you build beautiful apps in record time. You can design entire app screens in very little time, with little to no configuration problems like the ones we find in Android XML and others. Best part is, you write your app once and you run thesame codebase ANYWHERE (Linux, Mac, Windows, Web, Android, iOS and counting )

If it's something you're interested in, check out my video to get started:

How many projects have you created with your knowledge of HTML and CSS? Why do you want to jump to learning another framework before becoming productive and efficient with your currently acquired knowledge?

Take it from someone that's been there, done that... It's really not a good idea. It's totally okay if you've some (really cool) projects you've done with these knowledge, but if not... Go to the drawing board first

Deicide:
How are you using C++ to build Android App?

Android NDK.

SegFault:

Well that is the norm, most people prefer writing libraries in both c and c++ as it makes it a more accessible library, the only problem c really has is that you're fully on your own unless you use all those flashy libraries and there's this tool that helps to find hanging pointers and all that.

The only thing I know how to do when it comes to debugging native code is to either read assembly listings, or use a debugger... All those performance profilers and memory checkers I do not know how to use

SegFault:

Weird enough I hardly fall into that memory leak shit though I realised the free function does not give the memory back to the system it simply uses it on the next memory allocation a real recipe for disaster if your data structures heavily use pointers which is why (before I lost access to my cousin's laptop) I started using arrays of data, allocate as a huge chunk when I need data and simply use pointers to access each unit, turns out this makes the program faster due to reduced flushing of caches. But one thing about C++ is that you may not want to use all its features but some other idiot from whom you might need his source code badly might use some bleeped up features like diamond inheritance or dynamic allocation which till this day just seems so useless. That diamond inheritance thing should have been removed by now.

Well, it's there but you don't have to use it. And about C++ libraries, I don't really use them. Most of the libraries I ever work with are either written in C, or I just write my own routines (writing my own routines is just an opportunity for me to learn, which I shamelessly do all the time. Most of them are buggy however )

I think the diamond inheritance thing has its uses, but like everything in programming, not using in appropriate scenarios can cause headaches.

SegFault:

You don go far oh. Imagine using that ugly beast called C++ to program went back to the bastard sometime ago on my cousin's laptop i been wan write back end using llvm, what an ugly language a lot of people even complained that they should have used C for the tool chain.

C++ is actually not bad for a language. I prefer C to it, but for industrial strength code, I'll still use C++. It allows me to do dangerous stuff while still protecting me from memory leaks and things I forget to do. C however, is completely off the rails... If you forget to free one memory block laidis, you're probably screwed... Worst of all, if the memory leaks are in several places, then the frustrations can kill you before you finish the project. C++ is forgiving Sha, in that you just wrap whatever memory you want to deallocate in a smart pointer and you can forget about the memory issues.

I don't use all of its features, cause I don't need them... What I do not like however is the standard library. The way they name things is extremely weird, and I'm really not a fan of it... Some things too I stay away from are move semantics and std::bind and other stuff I cannot wrap my head around. Usually I stick with smart pointers plus classes and that's about it

Right now, the problems I'm having have nothing to do with ffmpeg or codecs... They're more about how to properly architect the code so that I can reduce memory allocations, usage and data copying...

It's been a while since I recorded any noticeable memory leaks (read smart pointers ), so I've gotten better with that one.

I'm a little terrible with multithreading in c++ however and always a little concerned about performance.

Seeking took ages to implement. Looking at it now, I must say that I was extremely naive with the way I implemented these things before... It wasn't my fault though. Most of these things are extremely undocumented and you'll have to do trial and error to gain proper understanding of them...

I'm currently learning how to write a demuxer, so I won't be having any need for ffmpeg anymore as android phones now come with lots of codecs for most popular formats...

Trust me, writing your own demuxer is fun, although extremely hard (by my standards). I'm gon ship this app with ffmpeg though, as I'm almost done with it (just the video editing features and audio processing stuff remaining)... I'll just have the demuxer project as a way to learn about how these formats like mp4, mkv and others work.

Ffmpeg was worse compared to libvlc when talking about documentation. However, it contains lots of codecs and is the lowest level I can go when talking about multimedia processing (unless I want to write my own codecs, which I'm not crazy enough to do. At least not yet )

Ffmpeg was extremely hard, as the api is ever changing, with little to no tutorials and documentation on how to do anything... So many new terms I encountered and I faced problems with extreme difficulty... At times, I think I'm just dumb, cause I read one thing like ten times and still don't understand what it means... Even the little documentation they provided I didn't understand... So I was going to give up on it and just go back to libvlc.

Something then spoke to me. If I'm going to always give up on everything I attempt simply cause its hard, I might as well just give up on my life itself... So I decided to just dive into it, giving myself a no-way out... I started creating a library to abstract the ffmpeg functionality so I can expose the media player features I want... It didn't work out, but I learned a great deal from the project...

I made another one that also didn't work out (I think I'll have about five or six media player apps I made with my knowledge of ffmpeg that will never see the light of day. They're still on my github, and they're fairly complete in their own right. I just cannot ship something I cannot use)...

The current one I'm working on has been going great, better than the ones I've worked on in the past... Now I'm much better with architecting code, thinking about algorithm design and fixing bugs... I've also gotten better with creating bugs, as I've lots of bugs in this current app I'm making. Now it's not as hard to think about a feature and implement it as it was when I started...

Nowadays, I play with the ffmpeg source code like I wrote everything. They're seriously not hard to comprehend now that I've spent some time with them... I even fix bugs in the library nowadays...

And my fear or inability to read other people's code is gone. I don't know what happened, but I'm now able to read people's source code and understand them faster than I ever thought I could.

There's still a lot more to do, but I've got to say that I'm proud of myself. It was extremely difficult to stick with programming, especially knowing I wasn't doing it for the money... Money is usually motivation to keep going, but even that I did not have... Nor did I have anyone to cheer me on as I embarked on this awesome journey that has brought me nothing but pure delight and satisfaction.

My family never understood why I sit in front of the computer every chance I get, and I'm sincere when I tell you that even I do not know why sometimes... Its my default mode now, and its clear that whether money or not, this is what I'll be doing for the rest of my life!

For a while, I was nothing but frustrated. Nothing was going the way I planned, and all the ideas I ever have, I know not how to implement...

I learnt about open source programs and discovered that reading real world code someone else wrote would help me learn much faster and see how things are done for real... Like most things however, it was extremely daunting... I didn't know why the author named some functions the way they did, what some functions do, so many jargon that required I read at least 100 pages of other jargons to figure out...

I could just ignore most things and just copy and paste code I find online, but I'm not a fan of using something I do not understand. I seriously do not like it. So I would read as many pdfs as I could, try to digest as much as I can (usually unsuccessfully) and will drop things I find too difficult to grasp...

This went on for years and one day I assessed myself and said, "exactly why are you doing this programming of a thing? You can't even do anything with the things you've learned"...

As for why I was still doing it even though it fetched me nothing, I just knew that everytime I sat in front of a computer to type code, I feel contented. Like I do not need anything else... I guess that probably comes from the fact that I think the outside world sucks, and appreciate having something that doesn't judge me when I do something wrong, takes all my bullshit without complaints and is always there when I need it.

Regardless, I wanted progress (who doesn't?). I decided to pick a department and settled for Multimedia programming. I decided to make a media player application first, then I would make a video editor, and then gradually progress towards becoming a game developer, focusing on the graphic or audio backends.

So I started the media player application. I was making the app for Android only, as iOS is very out of reach for various financial reasons.

I found Android has this API called Media Player for playing media. However, I found that it couldn't play one media file I downloaded online, so I figured it's not a viable option for me. Mx player could play everything, so I'm either making something as good as mx player or I ain't making anything at all. I found Exoplayer.

Exoplayer was good. However, it was extremely overwhelming in my opinion because there was too many pluggable components. These components I didn't understand what they did at the time... Coupled with the fact that exoplayer does not introduces any codecs of its own, so its subject to the same limitations at the media player option I first had.

I kept looking and found libVLC. This one is a little bit weird, cause the app is the most popular media player on desktop... While the API was well documented, there was very little examples on how to use it. So if you don't know how to read source code, you're pretty much toast... And it's an extremely huge library.

Anyway, that wasn't going to stop me from trying it out. I downloaded the library and the source code for the android app and I started trying to figure out how everything worked... I successfully created a media player with the library and it worked pretty well...

For some reason however, I wasn't satisfied. The app worked great, but the libvlc library was too big in my opinion. My friends encouraged me to ship the app then but I didn't. I maintained that I didn't like the app and that I had to change the libvlc backend...

To be sincere, there was nothing wrong with the app, nor was there anything wrong with the app size. The problem I had was that I had absolutely no idea what libvlc was doing in the backend and it bothered me. Making the app didn't feel as "fun" as I would've loved, since I spent time writing xml and linking views to activities and fragments. So I decided to go a little lower level and I took on ffmpeg. This was an extremely bad idea �

I'm creating this thread as some sort of documentation of my journey through learning programming and where I currently am. Think of this as a diary of some sort, but will only be relevant to programmers or aspiring programmers.

Before I started learning programming, there's not much I was doing with my life. In truth, life doesn't really mean much to me, cause I've never been able to properly wrap my head around things we humans do like religion, life and death and a bunch of other things in between... However, there's something I've always wanted: an opportunity to create something of my own. Something I can control. Games gave me that feeling when I was young. Being able to play mobile games fascinated me because I had some sort of control over decisions in the game and therefore can influence the outcome.

Later, I started wondering about who made these games and how they made them. This was still early and I very was young, so I didn't really understand much and didn't know where to look so I just dropped the whole idea.

When I grew older and started working, I had already gained understanding on how to use search engines, and so I resumed chasing my childhood dream... I was greeted with a wealth of information that was extremely confusing...

It took me lots of years to understand what a programming language is and why I needed it to make games. As I was reading articles online, I stumbled on some recommendations stating that you'd need to understand data structures and algorithms to be able to do anything related to programming.

With the already confusing concepts of programming languages that I still had no idea why i was learning them and what I was supposed to do with them once I finished learning them (coupled with the fact that they were extremely hard to learn, since I was on my own), I added data structures and algorithms to the mix and was learning them without knowing why. I just knew I had to

PeaceJoyLove:
Building a business is still the same. I created a thread about it, and I am still discussing this issue. But programmers have started attacking me. Lol. Anyway, the truth is bitter. They are programmers and only good for coding. They dont have business sense so they fail. And they will always fail. It is why they will keep working for people with business brains. The requirements are:

1. Innovation Intuitive ability
2. Able to raise capital (tell your story to attract investors).
3a. Use Capital Wisely. Give a programmer capital, he will even waste it. Give him 1 billion naira, he will develop a sophisticated app that no one will ever use. Lol. And he will waste money on promoting what people do not need. I have seen
3b. Drive home income. Your sales must be more than your expenses. Programmers canog sell. They dont know how to market. And to sell, what the customers need must be made. Programmers just build what they think customers need, and no one patronizes them. Coding is not needed to know what is going to sell. You need a business brain.

At most, programmers will grow to become Chief Technology Oficer (CTO), and if smart, can become a cofounder. But these ones in Nigeria think they have the business brain too. Lol. Las Las...they will end up in Fiverr for the rest of their lives. If lucky, they will get into one of the good companies and work in the design department. May 0.5% of them will actually build a good business. They are meant to work for someone with business intuitive brain.

But they can learn the skill if they are humble and build businesses. This is what I am presently discussing in my thread.


If you know a failed programmer, or a struggling one, just send me his previous work, and I will show you why he is not making it. They always do what has been done. They arent innovative. Someone needs to tell them what to do and write. They are like learners who must be guided. They are masters who cannot be left alone. This is the way Steve Jobs guided and led his main guy - Woz. Woz is good, but wouldn't be great if not for Steve Jobs.

Let these people get it into their brains that they must start learning business intuitive skills if they want to build their own businesses. But no, they will always bury their heads in the corner of their room talking to their computers alone Na that person go build a business? Business is relating with people.

Lastly, they have terrible attitudes in Nigeria. When you work with them, you will know. They want to work only for big companies but the opportunities in those companies cannot go round them all. The rest who do not work in these big companies are bittered. They will charge small companies like charging an already established companies (what they cannot even pay themselves).m, and at the end still do rubbish. You will start running after them to correct errors after they have been paid. They dont honor contracts at all. See eh! They have terrible attitude.

They will be alright. No one is taking them serious again. Business guys are looking at partnering with indians online. This is the way forward. But I just want to put my ideas on NL to help new guys so they dont take the attributes of these ones who have failed. I am going to have no mercy on them with my thread..I will say the truth as it is. He who has hear should ear. As far as I am concerned, it will take the grace of God for me to partner with anyone one of them cos their attitude is terrible.

If you think I am exagerating or too hard , try 20 of them. You will meet same attitude. But just port to using indians, and you will see what I am saying. Forget oooo. They will never make it unless they change.

Goodluck!

Lemme say this. First of all, thank you for these words... Most of these things hold true in most cases (at least for me) and they're things I believe I need to keep me in line. Once again, thank you. I do not have any excuses to make and no objections... You've spoken what I believe is true, however harsh they may be

Now I personally despise windows (as a programmer) cause they make working with stuff unnecessarily hard and if you ever write native code and use the ndk with existing c libraries, you'll be cursing windows every step of the way...

However, I've worked with windows in the past and it's actually quite easier to set up android studio for offline installation compared to other platforms. To make your life easier though, I'll just say that you should get yourself a computer that has internet connection, download all the dependencies you need (android studio, gradle, and some other deps). Then there's this offline maven dependencies thing on the android studio download page which is about 3GB... If you download this and set it up as per the instructions on the site, you're not going to need other dependencies apart from android studio, the android SDK, and gradle.

Which is why I say you should get internet on one of the computers, download android studio and the SDK and gradle. Then just copy the android studio and SDK to the other computers. For gradle, you can copy the .gradle folder located in AppData/Roaming (this should be in C:\Users\{Your_UserName}) to the equivalent locations on the other computers... Then you'll do the offline maven repo thing on each system and you should be set.

However, if you don't have access to internet on any of the machines, lemme post this first...

Your assumptions are very wrong on a whole lot of levels.
I've witnessed linux boot errors to due to failed headers update, the only saving grace was Rsync
Whomsoever borrowed his pc must have messed with it somewhere
I program on MacOs, Linux and Windows everyday, this message was posted from Windows
and I have never had any issue with Windows in my programming career, not even a BSOD.
And windows 10 was the next best thing after windows 7. windows 8 was a failed experiment
Why people have issues with windows is cos they often installed cracked versions and therefore disable system updates, [plus disabling system updates to save data]
I would advise anybody using windows for professional development to install a genuine version and have peace of mind
and if you have enough bandwidth, please allow automatic system updates. Its very critical for system stability, even Linux too.
if it wasnt, then Linux wouldnt have introduced "canonical livepatch", but i guess, you dont' know what that means.
cheers

Okay, I personally do not like Windows, so I'll probably be bias with this. I've used Windows XP, 7, 8 and 10 before and of all of them, Windows 7 is my personal best. It's the most stable and for people like me that don't like to waste data on updating or patching nonsense, Windows 7 just about did it for me. I didn't like Windows 8 and 10 for any reason, cause they're too bloated. By default, they come with lots of unneeded nonsense.

My major beef with windows though is that I'm the kind that likes to compile every open source library I use myself (I'm talking C++ here), instead of using prebuilt libraries. My God, Windows is the most frustrating operating system in that respect. That's why I switched to Linux and I've never looked back since.

Your "cannonical livepatch" thing is entirely optional. I usually don't like to update my OS, unless there's some serious security patch I need to incorporate, and even those I look at very carefully before doing it. Linux is very notorious when it comes to updates, and I don't want my perfectly working grub2 to start giving me errors I've never seen in my life. I ain't debugging any boot-weirdo thing.

Anyway, as always, windows sucks!!!

Please, seasoned freelance writers in the house, I need your help. I am currently broke as hell and I really need a job to get some money so that I can get a laptop and start painting so I decided to try writing for money, so please I need some advice on how I can start freelance writing – article writing, book writing, content writing. Please help a brother out.

As far as I know, people only want to employ someone that's already got some form of experience, so that's what you need to work on first. You need to build your "writing portfolio". What I mean is, you probably need to own a blog or something (or write for free for some people) just to get yourself some form of working experience. Then go to these freelancing websites (like Upwork or Fiverr) and get yourself an account. Fill in your experiences with references to articles you've written, and start applying for jobs from there.

If you're really serious about this content writing of a thing, then I'll recommend you learn another (global?) language apart from English. This will open so many doors for you, eh? I'm currently doing so myself, although it's not for content writing or anything like that. Being multilingual will set you apart from other content writers and will give you an edge.

Anyway, that's as much as I know. Hope it helps.

Many users here are not tech savvy and simplicity is cute. Though there might be some things that need adjustment or an upgrade, but Nairaland is fine the way it is bro

Yeah, simplicity is cute, buh sometimes we just have to try new stuff. Nairaland has been like this for only God knows, and even though we love its speed, simplicity and all, you have to understand that technology is advancing every day, which means that the speed you're worrying about will soon be a non-factor (if it is not already, as we're now speaking 4G, 5G), and the simplicity sometimes just tramples on features and functionality (no major feature added to Nairaland since forever).

And if we think about it, modernizing the UI will not make people not use it, will it? Twitter constantly upgrades their site, reddit too, and they've still got huge visitors using their site every minute. Compare this to Nairaland that is now turning to a historic thing, you know, something people look at and be like, "Yeah, a Nigerian made this". It's only a matter of time before a serious entrepreneur will come and take the ball from Seun. I hope not, cause I love Nairaland, buh... At this rate, I'm not a fan of no-change.

You're still naive. You think it's about design abi.. am a webmaster too. Simplicity is class. Seun has left this website like this for decades, do you think he's stupid? i bet you don't know all those your design up there will affect the SEO, page load time and some things you're not seeing.

There's something wrong with the way you're thinking. So, for some reason, you didn't think to look around you to see that what he designed is already being used by so many tech companies in the world. I wonder why they didn't think like you are thinking right now. They're dumb too, right? Yeah, I get it. People like you are the reason why we don't tend to move forward in this country. You think once something is there and it's working, we don't need to improve on it. Let's just leave it like that. Android 2.1 was okay, but if Google and Co. had left it as it was, would it be the Android OS it is today? The design will affect SEO, page load time. Which SEO is it affecting? A mobile app will affect SEO? Please explain, cause I've never seen anyone complain of such before, not even Google, Twitter or Facebook, and they've got tons on app that are WAY more complicated in designs.

Friends often ask why USB ports on my Mobile & Stationary Laptops don't work and I just tell them they're all Bad but they never know the actual Truth.

Even on my Mobile Phone(s), am so weary of what Apps I install on them. I can use a phone and all that's installed on it is WhatsApp and Mozilla Browser for emergency Net browsing. As for pre-Installed Apps, I just root (a Must for Me) and remove them all and in some instances, even had to perform a Factory Reset because I ended up removing something that made the phone unStable.

Yet you see people having so many Apps on their device most of which they've either forgotten about or don't even know it's there.

Common Banking Apps sef, I no get. I either use Quick Teller, go to nearest ATM which is within a Banking Premise (I don't trust those in Public places e.g at Eatery, Mall, Petrol Station, etc) or I just waka enter bank.

Security is never 100% but you just do what you could do.

One easy way to Hack people is to distribute Malicious Apps, Softwares, etc. People download them and ...

And what's with you and such sensitivity? Are you a bad person, or do you do bad things?? I understand you're being careful or something like that, but only people that's got something to hide are as careful as you are. But then, who am I to question how you live your life?

It's just odd for me, that's all. But answer the question on whether you do bad things or not.

And, did you delete all the USB drivers on your laptop to make them not work? Abi you disabled them in BIOS? Tell me please, I want to learn jawe

...but Hosting an APP on GCP, Azure, AWS, etc doesn't make the app secure if the APP it self isn't.

Hacking requires Extreme Knowledge + Patience + Willingness to Earn Gratification Later and Not Now, among other thing Most of which Most Nigerians don't have.

In fact Most Nigerians Using any Linux Variant instead of Microsoft Windows are only doing so because they've heard it's what Hackers or Serious Computer Wizards use; not because they really know what they're doing.

And even when they try using any Linux OS, they make sure to Dual Boot it alongside Windows OS .

Yea in this part of the world, most of us are after Instant Gratification and nothing more.

Kai, come off it!!! What do you mean by the people that use Linux in Nigeria use it because it's what hackers use? That's not why I use Linux. I've been a serious Linux user for about 5 years now and since then, I've not looked Window's way. It has something to do with the fact that I love to compile most of the stuff I use myself, love the freedom and simplicity of the Linux OS, love the fact that it's free and open source, the fact that it's extremely customisable, and finally, because I hate Windows.

So don't trash any Linux user in Nigeria cause I'm one of them and I won't stand for it. I'm not an hacker (yet, but I'll be one soon ), but that doesn't mean I don't have a licence to use Linux. And finally, I didn't dual-boot with any stupid Windows. It's my Arch Linux and Elementary OS all the way...

A leftist is a person who believes an egalitarian society and social equality. That is everyone should have equal rights and opportunities in the society, they believe that social hierarchy (classes) should be scrapped out of the society. Opposite of leftist is a rightist which is opposite of everything a leftist is. Leftism has different schools like communism, socialism and others. I was a hardcore communist but now nah I'll just call myself a leftist because I don't believe in collectivism (nah you must google this one I know you love learning but this one check it yourself).

Yeah... I just checked out the collectivity thing. It's simply prioritising some group over the members forming such group.

I'm a fan of the social equality thing, buh as you know, all fingers are not equal.

I don't like to call myself any of these names (probably cause I never heard of 'em, but I know who a pessimist is and I ain't one. I wonder what your cup of tea is with that one ), but if I'm to pick a side, I'll call myself a middlist cause I'm like stuck in the middle of all these things leftist and rightist. I don't believe there's a right and wrong way to do things. Things are just the way they are, and we're better off not judging them by categorising them as right or wrong.

A flat binary is simply a binary file, you remember those useless formats that you have to learn and understand like PE and ELF, they aren't in flat binaries, simply put they contain bare machine code and data simple.
