海外TECH	DEV Community	Five whopping-useful web dev tips I used in my newest project	https://dev.to/ironcladdev/five-whopping-useful-web-dev-tips-i-used-in-my-newest-project-564b	Five whopping useful web dev tips I used in my newest projectI planned this project for a while and finally just got it done In this project I completely remade Replit Apps with a whole bunch of features So originally replit apps had no limitations on what image could be uploaded for a cover image and the original algorithm left some projects either trending for months on end one of mine is still trending after eight months or nobody sees your project This created a problem that some rickrolls pranks and other low quality projects would trend forever I decided to change that by creating a new algorithm adding some highly requested features and many more beneficial attributes Let s get into the tips Making a feed hotlist algorithmIf you ve ever wondered how to make a constantly updating feed or hotlist algorithm you ve found the right place As an example posts on dev to constantly update the most popular ones getting bumped higher and higher to the top of the list the more likes they get every day Older posts that don t get as many reactions over time slowly fall to the bottom Each post has a z score that represents the popularity of it over time As time goes on the z score will drop and the post wills top trending First start by creating some database schemas In this one I ll just use a title likes views an array for holding the social data and finally the z score title String likes Number views Number sData Array z Number An example post would be something like the example below By default I start the z score out with a default of ten title Post likes views sData make sure sData has two nested arrays z Now for the algorithm function testTrend t y z let T t t t let Y y y y let Z z if T Y lt Z Math abs T Y else Z Math abs T Y return Number Z toFixed The t today parameter is an array of two elements views likes and so is the y yesterday parameter I am just using yesterday and today as examples Of course you could set the algorithm to update every fifteen minutes or so The last parameter z is for the z score of your database item Just plug the correct value in In this example I will be using mongoose js with mongodb for the trend algorithm You should be able to relate with another javascript database driver easily let posts await Post find id find and get every post s id field for var i posts length i loop through all of the posts let id posts i id get the ID of the post let post await Post findOne id id get one post let postStats post sData get latest social stats let viewsToday post views postStats let likesToday post likes postStats let newStat postStats viewsToday likesToday update the stats to get the latest amount of likes and views post sData newStat set the social data to the current latest amounts of likes and views over time let prevZ post z get the z score of the post post z testTrend newStat newStat prevZ calculate the new z score post save save That might ve been a bit confusing to understand Overall the algorithm calculates how many likes and views a post gets over time and recalculates a z score If there are more likes and views then the previous update the z score increases and vice versa Now to update this every once in a while Basically what I did was just hook the hotlist algorithm up to an api route and stick it into Every time the api route is called it updates the posts If you have a lot of users using your application you ll see the trend algorithm working Unfortunately this isn t exactly the most accurate algorithm and sometimes goes a bit haywire Feel free to adjust it and find the best results Capturing a snapshot of a websiteI literally pulled my hair out trying to find the solution Just before I went bald I found a thing on heroku that you could just run and deploy This really doesn t count as me coming up with a solution since I just found it but man did this make my life easy I launched the heroku app and literally all you have to do is just make a GET request to and you will get a png base string that displays the website image fetch google com then r gt r json then data gt document getElementById my image src data image User FollowingThis project isn t suited for like production level production so I used a JSON file for this To make it so that users can follow each other all you need is a JSON file or database if you are using it for production and some way to display who follows who An example of the type of schema you will need to use is shown below user String userAvatar String image url follows String followAvatar String image url For example if John Doe follows Jane Doe this is how we ll set the schema user John Doe userAvatar follows Jane Doe followAvatar All these objects will be stored in the json file as an array or in the database as a document To get the followers of a certain user run through the array and filter out all the follows that match a user s name let followersOfJohnDoe allFollowers filter f gt f follows John Doe And to get who John Doe follows do it the other way around let followersOfJohnDoe allFollowers filter f gt f user John Doe That s basically it NotificationsThis example is for basic notifications Not SMS or email notifications although you could easily hook up those As for notifications we have the fields Title Link when a user clicks on it Icon Description who it is for and if it has been read title String link String icon String url description String read Boolean defaults to false userFor String Number ObjectID user s id Some examples from the projectIt should be pretty simple for you to add a notification to the database and display it to a user I created a global function to write one that is accessible all over the app s backend and immediately sends one to a certain user After collecting all the notifications that are unread and are for a particular user you can display it and create a function that marks them as read Tag InputIt s always fun to tag your post on DEV or anywhere else but it seems a bit difficult if you tried to make one eh It looks hard but in fact is really simple Luckily I made a handy react component for you that works like magic First import your stuff import useState useRef from react Next create the component function TagInput return lt div gt lt div gt lt div gt lt input gt lt div gt Now assign a ref to your component When tags get long this should overflow automatically We ll need to autoscroll to the end once that happens Also let s make our state handlers function TagInput const tags setTags useState array of tags const t setTag useState the input current tag const inputRef useRef null return lt div ref inputRef gt lt div gt lt div gt lt input gt lt div gt Now let s just go overkill and add all the event handlers in yes it s ugly function TagInput const tags setTags useState array of tags const t setTag useState the input current tag const inputRef useRef null return lt div className styles tagWrapper gt lt div className styles tags gt tags map x gt lt div onClick gt setTags tags filter y gt y x setData tags tags filter y gt y x className styles tag key x gt x lt div gt lt div gt lt input placeholder Add Tags maxLength className styles tagInput onKeyUp e gt if e key Enter e key amp amp tag length gt amp amp tags length lt setTags new Set tags tag setTag setData tags new Set tags tag onChange e gt setTag e target value replace s g replace a z g value tag gt lt div gt All the handlers and listeners are there for you Have fun adding the CSS gt Well that s it for today If you liked it be sure to give this post a couple reactions and do me a favor by giving the project a like on replit I m in a hurry to regrow the hair I ve pulled out of my head Happy coding y all	2022-01-27 00:37:03
海外TECH	Engadget	One of Amazon's seller programs has been found to be unlawful	https://www.engadget.com/amazon-price-fixing-sold-by-amazon-antitrust-001247648.html?src=rss	One of Amazon x s seller programs has been found to be unlawfulFollowing an investigation into its Sold By Amazon program Amazon has agreed to pay the office of Washington State s attorney general office million and provide annual updates on its compliance with antitrust laws Available between and June the program set a pricing floor for certain products which the Attorney General s office says quot constituted unlawful price fixing quot Amazon enrolled a small number of third party sellers into the program while it was available The retailer promised sellers they would earn a guaranteed minimum on their products provided they agreed not to compete with the company What s more merchants could earn additional revenue if Amazon s algorithm determined consumers were willing to pay extra for their product with the company splitting the difference between them quot For example if a seller and Amazon agreed to a minimum payment and the item sold for the seller would receive the minimum price and share the additional profit with Amazon in addition to any fees quot Attorney General Bob Ferguson wrote nbsp According to Ferguson the problem with the system was that it set the minimum price of a product as the floor of what Amazon would offer to consumers When the price of their goods increased some sellers saw a “drastic decrease in sales in part because some consumers would opt to buy similar but more affordable products from Amazon and its various private labels The program according to the AG was in violation of antitrust laws The state opened its probe into Sold By Amazon in March The program was discontinued in June of that same year but according to an Amazon spokesperson for reasons unrelated to the attorney general s investigation As part of its agreement with the state the company won t offer the Sold By Amazon program again “This was a small program to provide another tool to help sellers offer lower prices much like similar programs common among other retailers that has since been discontinued the company said “While we strongly believe the program was legal we re glad to have this matter resolved When pressed Amazon declined to say why it did not challenge the resolution In recent years Amazon has faced intense scrutiny related to how it operates its online marketplace In The Wall Street Journal published a report claiming the company had been using proprietary seller data to help design and price its in house products In a Senate hearing former Amazon CEO Jeff Bezos said he couldn t “guarantee the company had not misused data from third party merchants on its platform Last week the Senate Judiciary Committee advanced the American Innovation and Choice Online Act legislation that would prevent companies like Amazon from favoring their own products over that of their rivals Like Apple and Google the company has aggressively lobbied to prevent the bill from passing	2022-01-27 00:12:47
