海外TECH	DEV Community	Advent of Code #1 (in JavaScript & Haskell)	https://dev.to/sethcalebweeks/advent-of-code-1-in-javascript-haskell-24in	Advent of Code in JavaScript amp Haskell This is my first year participating in Advent of Code and I thought I would use it as an opportunity to get better at Haskell and find similar approaches to problem solving in JavaScript I m actually planning to solve each puzzle in whatever method I think I can find the answer the fastest then go back and find a better solution in Haskell after getting the right answer Today I used Excel which is actually a great programming interface but more on that some other time I will summarize the problems here but you should really check out the website to get the full story and to join in Part OneThe puzzle input gives a list of numbers and we are asked to find the number of times that two consecutive numbers increase for the whole list My initial thought when asked to compute a single value from a list of values is a fold reduce Unfortunately each step in a fold for this problem would need to keep track of the running total of consecutive increases along with the previous number A common trick to get this work in Haskell is to first zip the list with its own tail to end up with a list of pairs of consecutive numbers like so There are better ways to write this but you ll see why I wrote it this way in part two list pairs a gt a a pairs x rest zip x rest restThen we can fold over our list of pairs to calculate the total of consecutive increases answer foldl count a b gt if b gt a then count else count pairs list There is probably a better way to do this in Haskell I tried to use a tuple as an accumulator containing the count and previous item but couldn t seem to get that working But that approach is relatively simple to follow in JavaScript answer list reduce previous count current gt current current gt previous count count Infinity The initial value to the accumulator is a tuple of Infinity so that the comparison with the first item will always be smaller and for the start of the count We use destructuring to pull the answer back out of the tuple at the end Part TwoThis part is similar to the first one except we compare consecutive sums of three consecutive numbers Sounds like we need triples from our list instead of pairs We can just extend the zip concept with the zip function triples a gt a a a triples x y rest zip x y rest y rest restThen we can map over that to get the sum of each triple Once we ve done that we are back to a list of numbers so we ll pair them up again to compare increases in consecutive sums and fold to get the total as before answer foldl count a b gt if b gt a then count else count pairs map x y z gt x y z triples list There are ways to fix the mess of parentheses but I won t get into that for now The initial strategy of using the tuple to keep track of the previous item and the total kind of falls apart for this part of the problem so we ll copy what we did in Haskell const zip a b gt Array Math min a length b length fill map i gt a i b i const zip a b c gt Array Math min a length b length c length fill map i gt a i b i c i const pairs x rest gt zip x rest rest const triples x y rest gt zip x y rest y rest rest const answer pairs triples list map x y z gt x y z reduce count a b gt b gt a count count That is certainly not a very elegant solution but we got there finally It took me about five minutes to solve both these parts in Excel but about two hours to put together these Haskell and JavaScript solutions How would you solve this problem in Haskell What about in JavaScript I d love to see some better ways than what I hacked together	2021-12-02 04:44:10
海外TECH	DEV Community	How functional programming made me an better developer, with Elixir	https://dev.to/nicolaslima321/how-functional-programming-made-me-an-better-developer-with-elixir-34eg	How functional programming made me an better developer with ElixirOn this article I ll share my experience with functional programming and how it help me to became an better developer practicing good programming principles like SOLID KISS YAGNI Also share some Elixir examples and applicability on Object Oriented Programming like JavaScript Functional Programming paradigm is an model that use only functions to solve your problems avoiding mutations states changes and all things that can provoke mutate in a data or process handling your data entire all process through only functions If you thought like me you probably got scare thinking about how to implement an algorithm that you don t have an object class instance all the OO Object Oriented particularities that we already know right That s make me a bit confused then i had to think outside my box and try to model and design my problems solutions using a different way And that was the process that make me start to became an better developer In my situation I gotta to learn Elixir that is an functional language with its syntax inspired by ruby I guess Elixir has an syntax not so friendly at beginning at least for me lol but is auto explainable and that is where the process start in Elixir Functional languages in general but I ll focus on Elixir you are forced to write codes self explainable cause in the most part your code will be a lot of functions calling themselves at side of a logical very well defined otherwise you will suffer with over engineering and confused implementations and just with that you already is getting inside on a software engineering principle very important that are KISS Keep It Simple Stupid To this usage for an example we gonna use an pipe operator Reference its syntax is gt what it does is to pass the previous value as a first argument of the function next to it Lets imagine the follow scenario a quite basic but We have an model Product and we must create an service to check if this product has on stock Pseudo code Abstracted logical and implementations def product is available product id do product id gt get product gt product has stock endNote this example have an defined flow you know at each line clearly whats is going on that is you getting the product id getting product through id with this product found check for product availability Has stock when is necessary you can apply in your code an flow like that independent of language to make your code ta have a good structure let s apply the same example in JavaScript Pseudo code Abstracted logical and implementations function productIsAvailable productId const product getProduct productId return productHasStock product the code is a little shorter but the clearly flow is the same Pattern MatchingIn Elixir you have an nice feature that is pattern matching Basically you have an input and a expected value so lets imagine the expected value is cake and your input is cupcake If you compare booths there s no match cause string cupcake doesn t match with cake So lets imagine we have an map that contains an program language it would be defined as language Elixir so lets create an function is elixir that checks if a given map is for language elixir def is elixir language Elixir do truedef is elixir language map do falseWhats happening here When we pass our map language language Elixir and call this function is elixir language it tries to proceed on the first match that is our first function definition but if we have an map like language C and try to call the same function there s no match on the first function then its search for the next match that is reached on our second function Because the signature generalizes language variable value not requiring to be an specific value So what if we call is elixir without any arguments It will raise an exception ´ No pattern match with function is elixir n it means the number of arguments of a function whats happened was it tried to match with first function clause but no success then tried to the second one but no success again then left no third to test so it raise this exception because of that We can demonstrate a kind of pattern matching in JavaScript with destructing lets do the same example function isElixir language return language Elixir in this case we receiving an object and destructing it through function signature the difference is when object given or not object doesn t has a key language it will raise an exception Cannot read property language it can be handled with an try catch clause Getting more deep Elixir doesn t have classes or properties It have modules with their functions to work with So when you thought in OOP you remember that if an class have a lot of responsability and differents contexts togheter it will bring a lot of readability problems and violates the first principle of SOLID single responsability Bringing it to Elixir it became even worst because all you have is a lot of mixed functions you don t have properties obviously have codes and projects written like that but is a terrible practice So segregating all theses contexts in anothers modules you will practice single responsability principle and now you have an code with modules properly segregated and you became able to manipulate it maintain it integrate with services and what else you need Now lets mix these concepts and get through examples even more deeps In Elixir we have an feature called with that is one of my favorite features With works like you having a lot of pipe operators gt but at each pipe you have a condition an pattern match for example and when not satisfy the defined flow it falls out of the clause going to an else when exists if there no match even on else a with clause match exception will be raised So lets imagine a kind of the product domain that we had discussed aboove but lets imagine we have an scenario that interact with anothers contexts all these through its services This scenario was a kind off an real problem that i dealed with in one of my personal projects that are we have an authenticated user and we suposed to get its current geolocation to store it and send it to a client who consum it a little complex right lol PS In a real scenario the best way to avoid this is to write an middleware to prevent non logged users to access use an feature These examples are only for lessons purposes So lets to the code Pseudo code Abstracted logical and implementations def treat current location user location do with ok true lt User is authenticated user ok coords lt Location get coordinates location ok lt Location save last coords coords do response message location successfully stored last location coords else unauthorized gt response current user is not logged error gt response an unexpected error ocurred endendNote in that code we used pattern matching on each with clause when not satisfies it tries to match in else clauses Note with this with this scenario looked at like an recipe of cake there are defined instructions and the only thing you need to do is follow this defined flow Now lets apply this example for JavaScript that was the real project solution lol Pseudo code Abstracted logical and implementations function treatCurrentLocation user location try if User isAuthenticated user false return response non authenticated const coords Location getCoordinates location Location saveLastCoords coords response message location successfully stored lastLocation coords catch error console log error return response an unexpected error ocurred In that code any raised error will be catched by our try catch so if destructs got no success or the Location module not return the expected value all be catched properly And also you have a defined flow of each thing is hapenning In this example you were able to practice YAGNI You ain t gonna need it discarding all unusefull process or values just continued following an defined flow ruled by KISS Keep it simple stupid	2021-12-02 04:21:49

Nebula Graph with K Why Load Testing Matters in Nebula Graph The load testing for the database needs to be conducted usually so that the impact on the system can be monitored in different scenarios such as query language rule optimization storage engine parameter adjustment etc The operating system in this article is the x CentOS The hosts where nebula is deployed are configured with C G memory SSD disk and G network Tools Needed for the Load Testingnebula ansible deploys Nebula Graph services nebula importer imports data into Nebula Graph clusters k plugin is a K extension that is used to perform load testing against the Nebula Graph cluster The extension integrates with the nebula go client to send requests during the testing nebula bench generates the LDBC dataset and then imports it into Nebula Graph ldbc snb datagen hadoop is a LDBC data generator Load Testing Process OverviewThe load testing conducted in this article uses the LDBC dataset generated by ldbc snb datagen The testing process is as follows To deploy the topology use one host as the load testing runner and use three hosts to form a Nebula Graph cluster To make monitoring easier the load testing runner also deploys PrometheusInfluxdbGrafananode exporterThe hosts where Nebula Graph is installed also deploy node exporterprocess exporter Load Testing Steps Use nebula ansible to deploy Nebula GraphSet up SSH
