海外TECH	DEV Community	Variables and Primitive Data Types in Rust	https://dev.to/vaultree/variables-and-primitive-data-types-in-rust-25de	Variables and Primitive Data Types in RustIn our last article we learned how to start a project in Rust This time we ll share tips on what you need to know about variables and their types We ll learn how to create and use them and discuss mutability and immutability constants and shadowing Variables Mutability and ImmutabilityVariables are spaces in computer memory used to store certain data We can think of them as if they were boxes to store some item In Rust when we declare a variable we use the reserved word let Check it out let x let y f y let x gt where x is the name of the variable and assigns the value to x Rust is a statically typed language that is every variable created must have a type In this line we are not adding a type because Rust can infer it according to the assigned data as in approximately of the cases However you ll find cases where Rust does not infer the type let y f y gt We can declare first and initialise later but it s very unusual to use it that way If the variable is declared and not initialised and we try to use it we will have a compilation error because Rust does not allow a variable to not have a value As a convention variable names that have compound names will be written in snake case such as explicit type By default Rust uses immutable variables which means that it is impossible to change their value after initialization This is a way to keep your code secure In the case below an error would be displayed let x x However we have the option of making a variable mutable for that we will add the mut keyword as follows let mut x x In this way we can make changes to this variable To print the value of a given variable do as follows println The value of x is x The is a placeholder that we replace with the value of the variable that comes after the comma ConstantsIn addition to variables we can create constants Constants will always be immutable and to create constants we use the keyword const instead of let and the type needs to be specified Another difference with constants is that they can be declared in any scope including the global scope They cannot be the results of functions or some value that could only be calculated at runtime Let s see an example const PI f ShadowingIn Rust it is possible to declare a new variable using the same name that was already used before and this new one overshadows the previous variable being able to change even its type Let s create a project to exemplify enter the directory and run VS Code cargo new variablescd variablescode In the main rs file we will replace the existing content with const PI f fn main let mut x println The value of x is x x println The value of x is x let x test println The value of x is x println The value of PI const is PI As we can see we created a variable called x and assigned the value to it which means that it is of type i It was created with the word mut meaning it is mutable so we could change the value of this variable by assigning the value to it Below we declare a variable with the same name but we add a text to it which means that the value has been changed and the type as well We could have used shadowing even if it wasn t mutable Let s run this project with the command cargo run The output will be similar to Compiling variables v home desktop dev workspace rust Finished dev unoptimized debuginfo target s in sRunning target debug variables The value of x is The value of x is The value of x is testThe value of PI const is As we can see Rust has good mechanisms to avoid errors that are very common in most languages forcing the initialization of the variable it does not allow for example a Null Pointer so well known in languages like Java C etc It s one of the reasons why so many people claim it to be their favourite language Moving on let s talk about how primitive data types work in Rust Primitive Data TypesRust has a list of data types that are considered primitive Rust primitive types can be grouped into scalar and composite data types What are primitive data types Primitive data types as the name implies come with a programming language They are built in and when combined can form more complex data types called non primitive data types As we mentioned the Rust programming language comes with a list of built in primitive data types that developers can use as building blocks for other data types Primitive data types in RustWe want to group them first into scalar and composite data types The difference between these two is that composite types contain multiple values ​​in one type whereas scalar types only contain one value Primitive Scalar Types in RustThere are four scalar primitive types that you should be familiar with in Rust Boolean data typeThe Boolean data type is said to be true or false like this let active true let inactive false Boolean data types are primarily used for comparing values or logic ーfor example to check whether a test score is A B or C Char data typeThe character type is a byte data type It is used to store single characters like let first a let second b let symbol ∞ Character data types are used to store single characters allowing the memory allocation in Rust to remain small Integer data typeThere are several types of integer data which fall into two categories signed i and unsigned u They include the following i i i i isize u u u u usize here are some examples let height ulet weight ulet size ulet data iFloating data typeFloating data types are always for f which can vary widely from negative to positive numbers f gt x to x f gt x to x Floats are what we call decimals See some examples below let interest let returns let agency Composite Primitive Types in RustArray data typeAn array is a data type that contains a group of elements Its size is always fixed and of the same data type like this let counts i let grade i In the examples above the array contains elements of the i integer data type while the array grade contains elements of the i data type String data typeThere are two string data types in Rust String String Object and amp str String literal The String object is not in the main language but is provided in the standard library It is also the most common string type because it is mutable To create a String String new let name String new name push str Pedro Aravena println name The amp str data type in Rust is considered a slice of string and is said to be immutable meaning that it cannot be changed during the lifetime of the program Take a look at the example below let name amp str Pedro Aravena let company amp str Vaultree In the example above for the lifetime of this program the name will always be associated with the string Pedro Aravena while the company will always be associated with the string Vaultree Slice data typeSlices are similar to matrices but there are some differences While array sizes are fixed slices are dynamic in size the length is not known at compile time and the data is split into a new collection Let s see the example below let grades let slice amp Slices are also a pointer to the above string object where we can retrieve a given character in the string value We can also borrow elements from a slice to use elsewhere Tuple data typeIn other languages like JavaScript tuples are called objects They are fixed data types that contain different types of elements ーunlike arrays which can only contain the same type of elements let employee amp str i amp str Pedro Aravena Developer Advocate In the example above the employee tuple contains three elements a string Pedro Aravena an integer and another string

海外TECH	DEV Community	Web Scraping With Java	https://dev.to/oxylabs-io/web-scraping-with-java-1ca2	Web Scraping With JavaSome of the popular languages used for web scraping are Python JavaScript with Node js PHP Java C and many others Every language has its strengths and weaknesses For now let s focus on web scraping with Java Web scraping frameworksThere are two most commonly used libraries for web scraping with JavaーJSoup and HtmlUnit  JSoup is a powerful library that can effectively handle malformed HTML The name of this library comes from the phrase “tag soup which refers to the malformed HTML document HtmlUnit is a GUI less or headless browser for Java programs It can emulate the key aspects of a browser such as getting specific elements from a page clicking the elements etc As the name of this library suggests it is commonly used for unit testing It is a way to simulate a browser for testing purposes HtmlUnit can also be used for web scraping The good thing is that with just one line JavaScript and CSS can be turned off It is helpful in web scraping as JavaScript and CSS are not required most of the time In the later sections we will examine both libraries and create web scrapers Prerequisites for building a web scraper with JavaThis tutorial assumes that you are familiar with the Java programming language For managing packages we will be using Maven Apart from Java basics a primary understanding of how websites work is also expected Good knowledge of HTML and selecting elements either by using XPath or CSS selectors would also be required Note that not all libraries support XPath Quick overview of CSS selectorsBefore proceeding let s review the CSS selectors firstname  selects any element where id equals  “firstname blue  selects any element where the class contains “blue p  selects all lt p gt  tags div firstname  selects div elements where id equals  “firstname p link new  note that there is no space here It selects lt p class link new gt p link new  note the space Selects any element with class “new which is inside lt p class link gt Now let s review the libraries that can be used for web scraping with Java Web scraping with Java using JSoupJSoup is perhaps the most commonly used Java library for web scraping Broadly speaking there are three steps involved in web scraping using Java Getting JSoupThe first step is to get the Java libraries Maven can help here Use any Java IDE and create a Maven project If you do not want to use Maven head over to this page to find alternate downloads In the pom xml  Project Object Model file add a new section for dependencies and add a dependency for JSoup The pom xml file would look something like this lt dependencies gt    lt dependency gt      lt groupId gt org jsoup lt groupId gt      lt artifactId gt jsoup lt artifactId gt      lt version gt lt version gt    lt dependency gt lt dependencies gt With this we are ready to create a Java scraper Getting and parsing the HTMLThe second step is to get the HTML from the target URL and parse it into a Java object Let s begin with the imports import org jsoup Connection import org jsoup Jsoup import org jsoup nodes Document import org jsoup nodes Element import org jsoup select Elements Note that it is not a good practice to import everything with a wildcard import org jsoup  Always import exactly what you need The above imports are what we are going to use in this tutorial JSoup provides the connect function This function takes the URL and returns a Document Here is how you can get the page s HTML Document doc  Jsoup connect get You will often see this line in places but it has a disadvantage This shortcut does not have any error handling A better approach would be to create a function This function takes a URL as a parameter First it creates a connection and then stores it in a variable After that the get  method of the connection object is called to retrieve the HTML document This document is returned as an instance of the Document class The get  method can throw an IOException which needs to be handled public static Document getDocument String url     Connection conn  Jsoup connect url   Document document  null   try      document  conn get     catch  IOException e       e printStackTrace    handle error     return document In some instances you would need to pass a custom user agent This can be done by sending the user agent string to the userAgent  function before calling the get  function Connection conn  Jsoup connect url conn userAgent custom user agent document  conn get This action should resolve all the common problems Querying HTMLThe most crucial step of any Java web scraper building process is to query the HTML Document object for the desired data This is the point where you will be spending most of your time JSoup supports many ways to extract the desired elements There are many methods such as getElementByID getElementsByTag etc that make it easier to query the DOM Here is an example of navigating to the JSoup page on Wikipedia Right click the heading and select Inspect thus opening the developer tools with the heading selected Image HTML Element with a unique classIn this case either getElementByID or getElementsByClass can be used One important point to note here is that getElementById  note the singular Element returns one Element object whereas getElementsByClass  note plural Elements returns an Array list of Element objects Conveniently this library has a class Elements that extends ArrayList lt Element gt This makes code cleaner and provides more functionality In the code example below the first  method can be used to get the first element from the ArrayList After getting the reference of the element the text  method can be called to get the text Element firstHeading  document getElementsByClass firstHeading first System out println firstHeading text These functions are good however they are specific to JSoup For most cases the select function can be a better choice The only case when select functions will not work is when you need to traverse up the document In these cases you may want to use parent children and child For a complete list of all the available methods visit this page The following code demonstrates how to use the selectFirst  method which returns the first match Element firstHeading  document selectFirst firstHeading In this example selectFirst  method is used If multiple elements need to be selected you can use the select  method This will take the CSS selector as a parameter and return an instance of Elements which is an extension of the ArrayList lt Element gt type Web scraping with Java using HtmlUnitThere are many methods to read and modify the loaded page HtmlUnit makes it easy to interact with a web page like a browser which involves reading text filling forms clicking buttons etc In this case we will be using methods from this library to read information from URLs As discussed in the previous section there are three steps involved in web scraping with Java Getting and parsing the HTMLThe first step is to get the Java libraries Maven can help here Create a new maven project or use the one created in the previous section If you do not want to use Maven head over to this page to find alternate downloads In the pom xml file add a new section for dependencies and add a dependency for HtmlUnit The pom xml file would look something like this lt dependency gt    lt groupId gt net sourceforge htmlunit lt groupId gt    lt artifactId gt htmlunit lt artifactId gt    lt version gt lt version gt lt dependency gt Getting the HTMLThe second step of web scraping with Java is to retrieve the HTML from the target URL as a Java object Let s begin with the imports import com gargoylesoftware htmlunit WebClient import com gargoylesoftware htmlunit html DomNode import com gargoylesoftware htmlunit html DomNodeList import com gargoylesoftware htmlunit html HtmlElement import com gargoylesoftware htmlunit html HtmlPage As discussed in the previous section it is not a good practice to do a wildcard import such as import com gargoylesoftware htmlunit html  Import only what you need The above imports are what we are going to use in this Java web scraping tutorial In this example we will scrape this Librivox page HtmlUnit uses the WebClient class to get the page The first step is to create an instance of this class In this example there is no need for CSS rendering and there is no use of JavaScript as well We can set the options to disable these two WebClient webClient  new WebClient webClient getOptions setCssEnabled false webClient getOptions setJavaScriptEnabled false HtmlPage page  webClient getPage Note that the getPage  functions can throw IOException You would need to surround it in a try catch Here is an implementation example of a function that returns an instance of HtmlPage public static HtmlPage getDocument String url     HtmlPage page  null   try  final WebClient webClient  new WebClient       webClient getOptions setCssEnabled false     webClient getOptions setJavaScriptEnabled false     page  webClient getPage url     catch  IOException e       e printStackTrace      return page Querying HTMLThere are three categories of methods that can be used with HTMLPage The first is DOM methods such as getElementById getElementByName etc that return one element These also have their counterparts like getElementsById  that return all the matches These methods return a DomElement object or a List of DomElement objects HtmlPage page  webClient getPage DomElement firstHeading  page getElementById firstHeading System out print firstHeading asNormalizedText   prints JsoupThe second category of a selector uses XPath Navigate to this page right click the book title and click Inspect If you are already comfortable with XPath you should be able to see that the XPath to select the book title would be div class content wrap clearfix h Image Selecting Elements by XpathThere are two methods that can work with XPath ーgetByXPath  and getFirstByXPath They return HtmlElement instead of DomElement Note that special characters like quotation marks will need to be escaped using a backslash HtmlElement book  page getFirstByXPath div class amp quot content wrap clearfix amp quot h System out print book asNormalizedText Lastly the third category of methods uses CSS selectors These methods are querySelector  and querySelectorAll They return DomNode and DomNodeList lt DomNode gt  respectively To make this Java web scraper tutorial more realistic let s print all the chapter names reader names and duration from the page The first step is to determine the selector that can select all rows Next we will use the querySelectorAll  method to select all the rows Finally we will run a loop on all the rows and call querySelector  to extract the content of each cell String selector   chapter download tbody tr DomNodeList lt DomNode gt  rows  page querySelectorAll selector for  DomNode row  rows     String chapter  row querySelector td nth child a asNormalizedText   String reader  row querySelector td nth child a asNormalizedText   String duration  row querySelector td nth child asNormalizedText   System out println chapter   t    reader   t    duration ConclusionAlmost every business needs web scraping to analyze data and stay competitive in the market Knowing the basics of web scraping and how to build a web scraper using Java can result in more informed and quick decisions which are essential for a business to succeed	2022-11-29 13:46:50
海外TECH	DEV Community	Next.js is a backend framework	https://dev.to/zenstack/nextjs-is-a-backend-framework-1mb9	Next js is a backend frameworkWhen I saw the below video the first reaction that came to my mind was exactly as Theo described Isn t Next js that React thing for building websites and web apps After a second thought I do realize that it is actually true Next js is the best backend to serve your react applicationAlthough Theo has made a strong point in his video I will explain my second thought from different aspects What does a backend framework do If we know what a backend framework does we should be able to verify this statement However after searching for a little while there seems to be no specific widely accepted definition of backend framework Indeed the framework is just a concept notion a pre prepared standard kit from which to work In that case let s look at the self positioned minimalist framework Express js to see what it does What does Express js do If you look at the Hello World example of Express js it s very simple const express require express const app express const port app get req res gt res send Hello World app listen port gt console log Example app listening on port port The essential functionality is to provide the ability to handle response request to a particular endpoint so called Routing which is the top item in the Guide menu of its website Of course besides the Routing there are also other important features like Middleware Error Handling you can think of it as the complementary ability to response request handling In other words it won t cause you too much trouble even if you implement those by yourself in some cases What does Next js do Therefore it comes to a simple question does Next js provide response request handling The answer is definite it does through its API Routes As most people might not be aware it also has Middleware feature Actually if you take a look at the package json of Next js you can actually find the express dependency below If it s built on top of a backend framework I guess it should count for a backend framework itself right Furthermore if you ask the early adopters why they are using Next js at first most of the answers would be for the SSR Server Side Rendering Indeed that s probably the most attractive feature from day one as you can see in the initial website front page No matter whether adopting SSR Server Side Rendering by getServerSideProps or SSC Static Site Generation by getStaticProps they are both running at the server backend What s the difference with the other backend framework Stateless vs StatefulIn Theo s video he seems to point out that it s the difference between Stateless and Stateful design However I don t have strong feelings about it personally Although I have been using Nestjs for several projects I always adopt a stateless design for scalability Moreover except for something like Websocket There are alternative solutions as Theo mentioned or you can just implement it using a separate backend I think we should always try to make a stateless design And in most cases we could achieve that by using centralized storage like cache database message queue etc Of course you can implement a similar pattern in Next js too But under the hood that s exactly what a framework does doesn t it The framework itself defines the conventions for how the code is written and structured which standardizes how the developers write their code But everything comes with a price and it does require a deeper learning curve which is deeper than the distance between Angular Nestjs and React Next js ArchitectureIf compared to Nestjs the underlying difference for me is the architecture as specified in Nestjs s official document However while plenty of superb libraries helpers and tools exist for Node and server side JavaScript none of them effectively solve the main problem of  Architecture Nest provides an out of the box application architecture which allows developers and teams to create highly testable scalable loosely coupled and easily maintainable applications The architecture is heavily inspired by Angular It organizes the architecture pattern and keeps it clean and modularized separating development concerns makes it extremely simple to maintain and scale the app A concrete example of the benefit for me was when I switched from one project to another one it was so much easier for me to understand the code of the new project and I could easily extend it with very less touching of the existing code However as the growing trend and big ambition of Next js it won t surprise me in the future if it absorbs the advantage of other frameworks and makes a good balance between easy to use and simple to scale Hope it would come soon When should I use Next js as my backendMunger has a famous quote All I want to know is where I m going to die so I ll never go there So I will instead list when you shouldn t use Next js as your backend instead You are totally fine with the current solution Your frontend is not based on React You do have to use a stateful design in your backend like Websocket You have something not convenient to be implemented in Javascript like some machine learning processing You have a very complicated backend processing logic and have different people to maintain different parts ZenStackIf you consider using Next js as your backend You could checkout ZenStack we are trying to build to help you fill the gap ZenStack is a schema first toolkit for building CRUD services in Next js projects Our goal is to let you save time writing boilerplate code and focus on building what matters the user experience See the tutorial I wrote about how to use it How to Build a Production Ready Todo App

海外TECH	DEV Community	SpringOne TLV World Tour Trip Report	https://dev.to/codenameone/springone-tlv-world-tour-trip-report-2821	SpringOne TLV World Tour Trip ReportMy talk was accepted by SpringOne in San Francisco I never went to that conference and was really looking forward to it This year would probably be amazing with the Spring and Spring Boot releases So many groundbreaking changes Unfortunately my travel budget at Lightrun was cut and I eventually left This meant I had to cancel the trip I would have paid for travel but San Francisco is both far and prohibitively expensive I ll have to take a raincheck This isn t exactly a substitute but a skeleton Spring Team is on a “world tour which reached Tel Aviv last week and I attended The venue is one I ve never attended the Peres center for innovation It s on the Jaffa beach and you can literally see the waves hitting the beach from the main stage Check out the photos below you can literally see people on the beach in some of them That s a fantastic venue The only downside is the distance from the center of Tel Aviv where I live But that s nothing compared to distances in the states…The event had registrations from over organizations This is the first Spring Tour outside of North America which is cool The talks were in English which I like but the Israeli accent is sometimes difficult to understand yes I know Unfortunately I had to leave early because I had to pick up the kids Before we proceed I want to say a couple of things about Twitter Over the past month I moved to Mastodon and it s pretty great There s even the Java Bubble which lists prominent community members on Mastodon Foojay added its own instance and interest is high I see no reason to stay on Twitter It s toxic and getting more so by the second I still have my account and I have a bridge that tweets my Mastodon posts So if you follow me there you won t miss anything But I won t go there as often and will try not to post there All the links in this post and future posts will refer to other networks whether LinkedIn or Mastodon Juergen Hoeller Introducing Spring Framework Spring Framework is a re alignment of the framework Juergen picked his works carefully focusing on the conservative nature of Spring versions and compatibility to past versions Spring Framework x is very much JDK based It s coupled to Java EE and the old javax namespace It s supported in open source until which means we need to make migration plans With Spring Framework x changes a few things JDK Jakarta EE instead of Java EE and javax namespaceAOT SupportVirtual Threads Loom This will be the basis to Spring Boot x The biggest challenge I foresee is the JDK requirement That might challenge some migrations As we make those migrations we ll probably containerize more Ideally that will make future migrations much easier JDK has some fantastic features though Juergen focused a lot on the language features but there are some great GC improvements for containers which make the upgrade worthwhile in the enterprise Migrating to the Jakarta API is a necessary evil since the packages for the old APIs are no longer updated This is going to be a migration pain but it s unavoidable This will require anyone who has a dependency on those APIs to move that code The entire Java ecosystem switched to fast release cycles and updates to frameworks like Tomcat happen at a much faster rate Juergen recommends skipping Jakarta EE and going directly to Spring Framework will still support JDK but it will also add support for JDK which should be available by then Jakarta EE will be the preferred framework for that version AOT is a tradeoff extra build setup and less flexibility at runtime Reduces startup time and memory footprint in production GraalVM is the de facto standard for native executables It has a strong closed world assumption no runtime adaptations Build time is very long Personally I don t think it s that long as a guy who built an AOT JVM OpenJDK static images Project Leyden Spring s AOT strategy is aligning with Leyden s JVM strategy Starting from a warmed up JVM image CRaC is also a promising option for fast Spring application bootstrap First class support for CRaC is expected in Spring Framework Project Loom is a preview feature in JDK that enables high throughput for Java threads They expect significant scalability benefit for database driven web apps It s also a perfect fit for messaging and scheduling applications This means WebFlux and reactive style is no longer primarily for scalability as Loom would provide that for “free Other features include fast bean property determination Complete CGLIB fork with support for capturing generated classes NIO based classpath scanning First class module scanning and further module system support possibly in HTTP interface clients based on HttpExchange service JDK HttpClient integration with WebClient but to me most interesting is the micrometer based observability for RestTemplate and WebClient During the break I had time to talk to Oleg Šelajev and Juergen The talk initially covered the future of CRaC Jurgen was very optimistic about its chances as a future capability in the JVM and the chance of integrating it into a reasonable workflow I asked him about the uptake of GraalVM and as of now the interest around the new versions focuses on other features There s excitement for GraalVM but it isn t a killer feature Yet I have some thoughts on it which I will share at the end of the post DaShaun Carter Introducing Spring Boot DaShaun showed a live demo of building with GraalVM and contrasted the sub second startup time enabled by the native image in GraalVM He then showed the RAM was a third of the full size JVM image Another part of the demo showed the actuator works as expected which is nice since GraalVM native image doesn t support the agent APIs in the current version The audience asked to see the size of the image which was half the size of the original image The demo was good but I ve used GraalVM on Spring Boot in the past so it wasn t new to me I asked about the uptake and traction they re seeing for GraalVM native image A lot of developers were waiting for Spring Boot to migrate to GraalVM and I m curious if this is something they can already see in Spring Initializer stats I wanted to know if the guys at Spring are seeing a flood of interest DaShaun said he wouldn t have made the trip if it wasn t for GraalVM But he invited me to talk later I ended up speaking to Juergen and got the answer I “wanted After that he pointed at which I wasn t aware of or forgot The scale of releases for November is amazing Cora Iberkleid Protect Your Microservices with Spring Cloud GatewayCora began her talk discussing some of the many use cases for a gateway She emphasized that traditionally there were lots of use cases for a gateway Spring cloud gateway is a lightweight approach to introduce a gateway that s very approachable in the Spring ecosystem They built it on the reactive stack and as a result it s fast and has high throughput since it s non blocking The gateway uses predicates in handler mapping and can filter requests responses In the filters you can filter apply rules and process requests dynamically then apply filters to the response to provide flexibility to the client Cora showed routing configuration in YAML and weighted routing to a web service She then moved to circuit breaking using a request limiter The request rate limiter is based on Redis and can throttle the amount of requests sent to an API with a replenish rate and burst capacity to block over usage of an API This is very useful to limit abuse and limit trial users Until now everything was done with pure YAML configurations The demo concluded with a custom route filter that changes the requests dynamically Dr David Syer Running Untrusted Code in Spring Using WebAssemblyThere are many cases where we might want to run untrusted code There are many ways to do that and as Dr Syer says WebAssembly is one of the best ways to do that Although browsers support hosting WebAssembly the focus of the talk is about server side hosting WebAssembly is a polyglot environment which makes it very attractive for some cases You can experiment with WASM directly in the Mozilla playground in MDN In the talk he discussed the various compilers you can use to generate WASM from C compilers to AssemblyScript etc See He provided an interesting link to a project for hosing WASM in Java Exchanging data with WASM seems painful and a bit of a throwback to communicating and copying data back and forth He provided two links of interest After the talk I had time to talk a bit with Dr Syer who was super nice My fundamental problem is that I never “got WASM How is it better than running Java in a sandbox The two use cases he mentioned were running untrusted code in embedded and edge computing As a guy who worked in the mobile and embedded division at Sun Oracle this stings a bit I get why this is the place where we re “at but we had JVMs running in very constrained environments with MVM and for Java capabilities It s still around it just never got the traction that WASM is gaining Another aspect is the Polyglot support Being able to do that for C or Rust code But that s not as interesting to me and for most of the use cases I can think of We obviously have good Polyglot options in the JVM but mostly in higher level GC languages and not so much in languages like Rust or C On the other hand we have many other capabilities such as GC deep native integration elaborate memory model etc I ve had this discussion with many smart people who see a lot of potential in WASM on the server Notice that this isn t about the browser where WASM has a valid use case It might succeed simply because of mindshare but as it stands right now it seems that WASM is a couple of decades behind what we have in the JVM world FinallyUnfortunately I had to pick up my kids from school and had to leave early so I didn t have time to see the talk by Oleg Šelajev about Test Containers or the many other interesting talks I did read the post on Test Containers but I guess the talk would have been more interesting I need to go to more of these things It seems I know more people when flying abroad to a conference than when visiting a conference in my country As I mentioned before I have some thoughts on why GraalVM isn t taking over everything overnight There are a few big reasons It s WorkMoving to GraalVM requires a lot of work from the developers Less so as time moves on But still a lot of things need to change Debugging is harder We need to generate builds in CI and we can t run them locally on some machines It s a pain Adding the slow build process to the mix makes this even more painful Dubious BenefitAs developers the memory and storage requirements we give are a given DevOps have cost reduction incentives that can benefit from GraalVM but they can t just integrate it They need developers to do the work In a corporate environment the cloud waste is already astronomical Sending a developer to migrate to a new VM so the DevOps team can get “cost saving credit That s not something that the R amp D management can get behind The incentives in a corporate setting are problematic Maybe the Spring team can arrange some viral marketing by helping twitter cut its cloud bill I m sure some of their microservices are Spring based ObservabilityWhile Spring Boot includes some monitoring tooling even with GraalVM The level of observability on GraalVM is lower at the moment no agent features That alone might have been OK but coupled with everything else it could be a problem We Don t Use ServerlessJava developers aren t big on serverless Over there GraalVM makes perfect sense and is already making great strides But serverless isn t as common in our community rightly so IMHO so the value for GraalVM isn t as clear To be clear I m very bullish on GraalVM personally I think it will eventually enjoy significant market share traction and has many things going for it But it will be a harder chasm to cross despite the obvious benefits	2022-11-29 13:07:14
