All those things in information technology world become more and more complex and if you deal with that, you really need to always be on the edge tracking new trends. It's quite hard but luckily, it's not a big deal to find any information related to the topic on the web. You can check Svitla Systems blog for example, I learnt a lot here.
Blockchain is interesting for business organization. Participants of the transaction can not fool each other. It does not need intermediaries like a bank. It does not have a central hub, destroying which can knock down the entire system. All operations are transparent for its participants as all data are entered into one database.
Alright , if nobody knew i used to be a game dev but i did quit because i had no friends so my point was a bit missing , and i'm going back to be a game dev , but this post isn't about that , ever wanted to be a gamedev? never had the money? don't have any skill or talent? don't know how to code? ; then no worries because you can still become a gamedev , all software and platforms listed below are completely free , no payments overtime etc.
1 - The Game Engine : you can't make a game without the Engine , I recommend : Godot [if you can code] , if you can't code check GDevelop [only 2d] out
2 - Design : now that you have your Game Engine the design is important , first you have to choose between 2D / 3D , for 3D modelling check Blender out , and if you can't do 3d modelling use TurboSquid for royalty free models , for 2D i recommend Gimp or Krita for vectors Inkscape if you can't draw i would suggest itch.io assets
3 - Music : for producing music for your game i recommend LMMS , or for downloading it for free i recommend : Dig CCMixter
4 - Sound Effects : okay you will need to know "Foley Art" for this one [recreating sounds with everyday items] , for editing the audio i recommend Audacity and for downloading i recommend soundbible
5 - publishing : so your game's done , now where do you publish it for free ; i reccommend Itch.io or Gamejolt
and you're done , congrats
[for Os you can use linux ]
This is really cool.
And I might consider this when I'm done giving exams.
