海外TECH	DEV Community	Is Machine Learning generated music finally useful? [for Indie Game Devs]	https://dev.to/inhuofficial/is-machine-learning-generated-music-finally-useful-for-indie-game-devs-1flp	Is Machine Learning generated music finally useful for Indie Game Devs A short post about a service I stumbled across called AIVA I have been working on systemising my processes for content creation One thing that I want to do is to create some YouTube shorts minute videos same as TikTok Instagram stories type videos and I was looking for some subtle background music that wouldn t be copyrighted While searching I stumbled across a service to generate AI music As with anything new and interesting I had to have a play First impressionsIt was easy to use even for a dummy like me You just select a few things such as what style of music instrumentation you want duration up to minutes for free tier tempo key and time signature and then select how many tracks you want the AI to produce up to at a time Then you press Create Your Track and wait for a minute or two You can then listen to the AI masterpiece or disaster Consistency resultsFrom about tracks I generated I would say that in tracks are decent enough that you could possibly use them a lot of them end up with too heavy a drum beat or some weird transitions etc Despite that I am impressed with the results Good enough for Indie game developers They aren t perfect but if you have next to no budget for sound tracks they will probably be good enough I found about tracks that I think would work for a low budget Indie game which isn t bad considering I did no editing on the tracks other than removing some weird bits from the end of the first example below With a bit of work and tweaking I imagine you could make them feel like high quality pieces composed just for the game Or at the very least use them as inspiration pieces to make the ideation part of music design a lot shorter and therefore a lot cheaper ExamplesHere are three examples I downloaded of tracks that I think are pretty much good enough for usage I have given them some fun names and the sort of game I think they would work for enjoy AIVAs work Example DrAIgon born Example PAIrates Adventures Example In SpAIce no one can hear you scrAIm So what do you think Do you think Machine Learning has come far enough to generate some useful music sound tracks Could you picture a game with one of these sound tracks in it I personally think some of the Hip Hop Low Fi and Easy Listening stuff it produces would make great background music for streams and videos the main reason I am exploring the service with a very slim chance of a copyright strike I would encourage you to have a play yourself and see what you think Quick PollCover image Unsplash	2021-10-10 17:52:10

海外TECH	DEV Community	Dotnet code generation overview by example	https://dev.to/maximtkachenko/dotnet-code-generation-overview-by-example-1m16	Dotnet code generation overview by example IntroductionCode generation is a very interesting topic Instead of just writing code you can write code to write code You can do code generation at compile time new fancy source generators and at runtime expressions emit IL Anyway the idea to create methods and classes at runtime sounds like a magic to me Runtime code generation feature is used quite heavily under the hood of DI frameworks ORMs different types of object mappers etc Now when I have a sufficient understanding of the topic I realized that in the past I had some tasks which could be solved in more efficient and elegant way by using code generation Unfortunately during those times I knew nothing about it Searching the internet gave me results with quite high entry threshold and they didn t give an entire understanding of the feature Most of examples in articles are quite trivial so it s still unclear how to apply it in practice Here as the first step I want to describe a particular problem which could be solved with metaprogramming and then to give an overview of different code generation approaches There will be a lot of code Task descriptionLet s imagine our application receives a data from some source as an array of strings for simplicity only string integer and datetime values are expected in an input array John McClane T I need a generic way to parse this input into the instance of a particular class This is an interface to create a parser delegate i e it accepts an array of strings as the input and returns an instance of T as the output public interface IParserFactory Func lt string T gt GetParser lt T gt where T new I use ParserOutputAttribute to identify classes used as parser s output And I use ArrayIndexAttribute to understand which property corresponds to each of the array elements ParserOutput public class Data ArrayIndex public string Name get set will be John McClane ArrayIndex public int Number get set will be ArrayIndex public DateTime Birthday get set will be T If array element can t be parsed to the target type then it s ignored So as a general idea I don t want to limit implementation by Data class only I want to produce a parser delegate for any type with the proper attributes Plain C First of all I want to write a plain C code without code generation or reflection at all for a known type var data new Data if lt inputArray Length data Name inputArray if lt inputArray Length amp amp DateTime TryParse inputArray out var bd data Birthday bd if lt inputArray Length amp amp int TryParse inputArray out var n data Number n return data Quite simple right But now I want to generate the same code for an arbitrary type at runtime or compile time Let s go ReflectionIn the first approach with reflection I m not going to generate a parser delegate Instead I m going to create an instance of the target type and set its properties using reflection API public class ReflectionParserFactory IParserFactory public Func lt string T gt GetParser lt T gt where T new return ArrayIndexParse lt T gt private static T ArrayIndexParse lt T gt string data where T new create a new instance of target type var instance new T var props typeof T GetProperties BindingFlags Instance BindingFlags Public go through all public and non static properties read and parse corresponding element in array and if success set property value for int i i lt props Length i var attrs props i GetCustomAttributes typeof ArrayIndexAttribute ToArray if attrs Length continue int order ArrayIndexAttribute attrs Order if order lt order gt data Length continue if props i PropertyType typeof string props i SetValue instance data order continue if props i PropertyType typeof int if int TryParse data order out var intResult props i SetValue instance intResult continue if props i PropertyType typeof DateTime if DateTime TryParse data order out var dtResult props i SetValue instance dtResult return instance It works and it s quite readable But it s slow check benchmarks section below too If you want to call this code very often it could be an issue I want to implement something more sophisticated using real code generation Code generation Expression treesFrom the official documentation Expression trees represent code in a tree like data structure where each node is an expression for example a method call or a binary operation such as x lt y You can compile and run code represented by expression trees How to execute expression treesExpression classesExpression trees give primitive building blocks like Expression Call to call a method Expression Loop to add some repeating logic etc Then using these blocks we build a parser delegate as a tree of instructions and finally compile it into the delegate at runtime public class ExpressionTreeParserFactory IParserFactory public Func lt string T gt GetParser lt T gt where T new var props typeof T GetProperties BindingFlags Instance BindingFlags Public declare an input parameter of the delegate

CreateDelegate Cache compiled parsersWe have implemented three approaches to create a parser delegate expression tree emit IL and sigil In all cases we have the same problem IParserFactory GetParser
