海外TECH	DEV Community	Polymorphism in C#	https://dev.to/pixelatedlagg/polymorphism-in-c-2g38	Polymorphism in C Polymorphism is a very important pillar of object oriented programming right up there with encapsulation and inheritance Polymorphism in Greek meaning many shaped this pillar allows for objects to take multiple forms This sounds more complex than it actually is so lets dive into some examples I have class A and class B B inherits A In Main this allows for some interesting behaviour class A class B A public class Program public static void Main string args A a new B No error How is there no error thrown I am clearly trying to assign an incorrect type to a variable Except I m not When B inherits A it becomes a form of A meaning it can be passed along as A when needed Let s look at some more examples using System public class Program public static void Main string args DoSomething new A DoSomething new B static void DoSomething A obj Console WriteLine Object Type obj GetType Output Object Type AObject Type BAnother example using System using System Collections Generic public class Program public static void Main string args List lt A gt objs new List lt A gt objs Add new A objs Add new B foreach A obj in objs Console WriteLine Object Type obj GetType Output Object Type AObject Type BI know you all are on the edges of your seats but let me inform you of another crazy use of polymorphism overriding methods But isn t that just inheritance I hear you ask And you would be technically correct Like all pillars of object oriented programming inheritance and polymorphism work hand in hand to provide you with the best features Now the method overriding can be done with two amazing keywords virtual and override virtual is essentially the method field raising its hand to be overridden in a form of the class override is the teacher calling on the method field to override it in a form of the class Let s see these keywords in action using System public class Program public static void Main string args DoStuff new A DoStuff new B static void DoStuff A obj obj DoSomething class A public virtual void DoSomething Console WriteLine I did something in A s method class B A public override void DoSomething Console WriteLine I did something in B s method Output I did something in A s method I did something in B s method Both objects were passed as type A yet had different implementations of the same method It is time to introduce the sealed keyword If using virtual is like raising your hand then using sealed is equivalent to keeping your hand down And unlike that one teacher who tries to engage the whole class the C compiler will simply not call on that method field to be overriden in a form of the class Yet another high octane example with us introducing class C class A public virtual void DoSomething Console WriteLine I did something in A s method class B A public sealed override void DoSomething Console WriteLine I did something in B s method class C B public override void DoSomething Console WriteLine I did something in C s method Output error CS C DoSomething cannot override inherited member B DoSomething So we can see that sealed cuts off the chain of overriding methods I know at this point you are in a code induced coma from the amazing keywords you just learned how to use but let me sneak one last keyword in the pile Continuing with the classroom analogy the new keyword is similar to that one overly enthusiastic student raising their hand and blocking another student behind them This results in the teacher calling on the student in front rather than the student behind And before you freak out I was also very surprised that the new keyword has another use than initializing objects Note When using a form of a class as that base class any new methods fields will not work in hiding the original ones Example using System public class Program public static void Main string args DoStuff new A DoStuff new B static void DoStuff A obj obj DoSomething class A public void DoSomething Console WriteLine I did something in A s method class B A public new void DoSomething Console WriteLine I did something in B s method Output I did something in A s method I did something in A s method The new keyword failed because of passing B as type A this is why override exists An example of new working using System public class Program public static void Main string args new A DoSomething new B DoSomething class A public void DoSomething Console WriteLine I did something in A s method class B A public new void DoSomething Console WriteLine I did something in B s method Output I did something in A s method I did something in B s method Now this hurts me as much as it hurts you but I need to introduce one last keyword And I know I said that new would be the last but this is what happens when you trust a C developer Anyways the last crucial keyword that you need to know is base The base keyword allows you to access the base class methods and fields from a form of it while not having to create a whole new object It is just as convenient as it sounds Example using System public class Program public static void Main string args new B DoSomething class A public virtual void DoSomething Console WriteLine I did something in A s method class B A public override void DoSomething Console WriteLine I did something in B s method base DoSomething Output I did something in B s method I did something in A s method If you want to learn about all of the possibilities of using polymorphism in C I would suggest further

海外TECH	DEV Community	Script to change Zoom virtual background every day	https://dev.to/saranshk/script-to-change-zoom-virtual-background-every-day-2cm4	Script to change Zoom virtual background every dayOver the past few months I found a new use of the pictures that I have clicked while hiking I started using them as Zoom virtual backgrounds If you are anything like me and take a lot of pictures it can be hard to decide which one looks good And then I decided to use them all on different days Sadly Zoom does not have this as a built in feature And being a Software developer I had to automate the process of choosing a random Zoom virtual background every day What does the script do Zoom does have an API that I could have used to change my background every day but that seemed like too much effort for this task Software developers are born lazy right Instead I found out that the Zoom application creates a copy of the background that gets selected in its preferences folder and references it The script just takes in a random file and replaces it with this background file And voila A different Zoom virtual background is shown This can then be put in a cron job to be executed every day or any frequency you prefer to periodically change the background PrerequisitesI have put all the images I want to use as backgrounds in a folder in my user directory Mine is at zoom bgpictures and that is what I use in the script but it is a variable that can be changed to whatever you want it to be Next we set a Zoom virtual background in our application It does not matter which one All we need is the unique ID that Zoom will assign to this background There might be some files already in the directory but we want to select the one that corresponds to the image that we just uploaded to avoid replacing a different file The directory is located at Library Application Support zoom us data VirtualBkgnd Custom The file name will be something like WAEF G EL MF APBCFAD The scriptWe will be using a bash script to replace the image we just used I will be putting this scrip in the zoom folder that I created for the background images It can again be named whatever you like I am naming mine as zoom zoombg sh The script is as follows bin bash The name of file that we copied before and will be replaced withOG BG WAEF G EL MF APBCFAD Directory where Zoom keeps the backgroundsZOOM DIR Users USER Library Application Support zoom us data VirtualBkgnd Custom Directory of our imagesBGPATH Users USER zoom bgpictures Picking a random fileNEW BG find BGPATH type f sort R head Replacing the filecp R NEW BG ZOOM DIR OG BG If you choose different paths for the directory change it in the variable We need to make this script executable by running the command chmod zoom zoombg sh Changing Zoom virtual background randomlyThe script is ready All we need to do is put it in a cron job which is a built in time based job scheduler We need to decide a schedule for how frequently we want to change the Zoom virtual background I do mine at AM every day since my meetings start at AM If you are new to cron jobs you can use the generator to help you I use Users saranshkataria zoom zoombg sh gt dev null gt amp The first part is what you will need to customize according to your schedule The second part is just telling the OS what to do at that point in time The path will need to be updated if you chose a different location for the bash script To put it in a cron job typecrontab eand it will open up an editor using vi Hit the I key on the keyboard to enter insert mode paste in the line and press Escape followed by “ wq and enter to save and quit That is all there is to it and we shall have a random Zoom virtual background every day frequency you chose If you are using Windows the script can be modified accordingly and should be fairly straightforward to use If you have any questions feel free to drop a comment below Originally published at on August	2022-04-13 02:13:07

海外TECH	DEV Community	Story-time: Tackling No Double Favorite Cat	https://dev.to/bperez3237/story-time-tackling-no-double-favorite-cat-56ha	Story time Tackling No Double Favorite CatI wanna talk about a feature I struggled with implementing on my recent project to use a public API to create a single page application So the idea for my project was to create an application to help someone pick their ideal cat to adopt The user could search from a list of cat breeds available on the and the search would return a few bullet points of information If the user likes a cat they can favorite that breed and the image and name will be stored in the favorites div while the user searches more cat breeds Before diving into the coding I thought the difficult part of this project would have been the DOM manipulation combined with the asynchronous behavior of the GET request But surprisingly I found myself stuck trying to perfect the favoriting feature for a good chunk of time So this is a section of what the basic application looks like after searching a cat breed If the favorite button is clicked a small image with the breed name underneath would appear in the empty favorites div The only constraints I wanted were Maximum favoritesCan t favorite one breed twiceOk easy enough First I tackled doing maximum favorites This would be called within a function handling the favorite click event listener newFavorite is an html div element with the cats image and breed name inside function checkFavorites newFavorite const favorites document getElementById favorites if favorites children length favorites removeChild favorites children favorites appendChild newFavorite else favorites appendChild newFavorite I test ran it and it worked fine Simple great Ok next part The first problem I had how was I going to check if the newFavorite cat breed I was passing into my function was already favorited The favorites are all added into the favorites div using appendChild newFavorite This is the HTML after one cat breed is added to favorites So I could check all the children of the favorites div element Probably easiest to iterate through favorites children and check if the breed name in newFavorites matches a child of favorites If I was to code this by itself without the cat limit this is what I came up with function checkFavorites newFavorite const favorites document getElementById favorites const currentBreedName newFavorite getElementsByTagName p textContent let checker true for i i lt favorites children length i if favorites children i getElementsByTagName p textContent currentBreedName checker false if checker true favorites appendChild newFavorite else alert AREADY IN FAVORITES The for loop iterates through all the current children of favorites and uses an if statement to check if the name matches the one I am trying to add I can t use appendChild within my for loop or else I could append more than once So I create a checker variable and use a second if statement to action the appendChild after the for loop is done Took me a little bit to figure that one out but sure enough this code works by itself Next step would be to combine it with the code I made to limit to favorites If combined in the right order this should work right I m not exactly sure why I decided to cap it at cats or even at all Maybe to help the user with decision paralysis or make it aesthetically pleasing or Anyways If I copy paste my first code block and put it right after my second code block it doesn t work If you favorite the same breed twice it will alert you it is ALREADY IN FAVORITES but when it passes the second code block since it hasn t reached children it appends the double favorited cat And vice versa if I order the two code blocks the other way I get the same behavior So still not working Maybe if I put code block in the middle of code block Code block inside the for loop of code block A nested if statement within a for loop within an if statement I wasn t expecting this to stump me but I was little low on morale at the time Maybe I should change my constraints to make the coding easier Somehow it eventually came to me If I combined the two if statements using amp amp I could get the elements appended removed in the right order to get the behavior I was looking for And much easier to read than some of the other options I was thinking of trying This is the final version of the function function checkFavorites newFavorite let favorites document getElementById favorites let currentBreedName newFavorite getElementsByTagName p textContent let checker true for i i lt favorites children length i if favorites children i getElementsByTagName p textContent currentBreedName checker false if favorites children length amp amp checker true favorites appendChild newFavorite else if favorites children length amp amp checker true favorites removeChild favs children favorites appendChild newFavorite else alert AREADY IN FAVORITES Combining favorites children length boolean with checker true allows me to appendChild only once and making sure I am following both my constraints at once Alternatively I could have done the same thing with else if statements but I think it would have affected the readability Simple enough I thought Anyone have a better solution	2022-04-13 02:01:20
