海外TECH	DEV Community	Advanced Techniques for Working with Ruby Collections 🎯	https://dev.to/eakmotion/advanced-techniques-for-working-with-ruby-collections-4l08	Advanced Techniques for Working with Ruby Collections Working with collections such as arrays and hashes is a fundamental part of programming in Ruby While basic operations like iteration filtering and mapping are essential there are many advanced techniques that can help you write more efficient expressive and maintainable code In this article we ll explore some of these techniques and show you how to take your collection based programming skills in Ruby to the next level ️Method ChainingMethod chaining is a technique that allows you to apply multiple operations to a collection in a single line of code For example suppose you have an array of numbers and want to filter out the even ones square the remaining values and then sum them up Here s how you can do it using method chaining numbers result numbers select amp even map n n sumputs result output In this code we re using the select method to filter out the even numbers the map method to square the remaining values and the sum method to add them up Combining these methods allows us to express our intent more clearly and concisely ️LazinessRuby collections are generally eager which means that they evaluate all their elements immediately However you can use lazy evaluation to delay the evaluation of some or all of the elements in a collection until they re actually needed This can be useful when working with large collections or when you want to avoid unnecessary computations Here s an example of how you can use laziness to speed up the processing of a large array numbers to aresult numbers lazy select amp even map n n take to aputs result output In this code we re using the lazy method to make the array lazy which means that the select and map operations are only evaluated on the elements that are actually needed in this case the first even numbers This can significantly speed up the processing of large arrays by reducing the amount of unnecessary computation GroupingSometimes you may want to group elements in a collection by a certain property or condition Ruby provides the group by method for this purpose which returns a hash where the keys are the grouping values and the values are arrays of elements that belong to that group Here s an example of how you can use group by to group an array of strings by their lengths words apple banana pear orange grape result words group by amp length puts result output gt apple grape gt banana gt pear gt orange In this code we use the group by method to group the words in the array by length The result is a hash where the keys are the lengths of the words and the values are arrays of words with the same length MemoizationMemoization is a technique for caching the results of a computation so that it can be reused later without recalculating the result In Ruby you can use memoization to cache the result of a method or a block of code which can be useful when you re performing expensive computations or when you need to calculate a value multiple times Here s an example of how you can use memoization to cache the result of a Fibonacci sequence calculation def fibonacci n Use an instance variable to store the cached results of the Fibonacci sequence calculation fib If the value is already in the cache return it return fib n if fib n Calculate the Fibonacci value and store it in the cache if n lt fib n n else fib n fibonacci n fibonacci n end Return the Fibonacci value fib n endIn this code we re using an instance variable fib to store the cached results of the Fibonacci sequence calculation We first check if the value is already in the cache and if it is we return it If not we calculate the value and store it in the cache for later use This can significantly speed up the processing of large or complex computations and also reduce the amount of memory needed to store the results You can use memoization in any situation where you need to calculate a value multiple times or perform an expensive computation Just be sure to keep in mind the potential trade offs of memoization such as increased memory usage or potential issues with stale cache values ConclusionWorking with collections is an important part of programming in Ruby and mastering advanced techniques like method chaining laziness grouping and Memoization can help you take your code to the next level So don t be afraid to experiment with new ways of working with collections try out different methods and techniques and see what works best for you You might just discover a new favorite tool or technique that transforms how you think about Ruby programming So go forth explore and have fun with collections in Ruby	2023-02-24 05:03:38
海外TECH	Engadget	DOJ accuses Google of deleting chat evidence for its antitrust lawsuit	https://www.engadget.com/doj-accuses-google-deleting-chat-evidence-antitrust-lawsuit-055524776.html?src=rss	DOJ accuses Google of deleting chat evidence for its antitrust lawsuitThe Department of Justice DOJ is accusing Google of routinely destroying internal messaging chat histories which the company is required to preserve under federal rules for an antitrust lawsuit Google is grappling with not just one but a couple of antitrust lawsuits filed by the DOJ and groups of states This particular case pertains to the lawsuit the department filed back in for unlawfully maintaining monopolies around search and search related advertising In the DOJ s filing it said company employees typically used their internal chatroom which was set to delete history every hours to discuss substantive and sensitive business Apparently the agency expected Google to change its chat history setting in when the company reasonably anticipated the litigation but it left the decision to individual employees Only a few people deemed their chat histories relevant to the case and preserved theirs for the court and Google continued deleting most people s chats even after the lawsuit was filed nbsp Despite that Google reportedly told the government that it had already put a legal hold in place to suspend auto deletion on its chat tool The DOJ alleges that the company s claim was a lie and that it only truly stopped deleting chat histories this week after it was warned that the agency would file a motion for sanctions It s now asking the court to rule that Google had violated a federal rule and to order a hearing that would determine how the company would be sanctioned The DOJ also wants the court to order Google to provide more information about its chat practices nbsp Google however denies the DOJ s allegations A spokesperson told The Wall Street Journal Our teams have conscientiously worked for years to respond to inquiries and litigation In fact we have produced over million documents in this case alone and millions more to regulators around the world	2023-02-24 05:55:24
