 After introducing a new component into our application, we noticed the page throws up an error  " react Cannot read properties of null (reading 'useState') " After some troubleshooting and analysis, we noticed that a different react version was deployment. So instead of a single version, we have 2 version and broke it.  The fix is to change package.json to use the same react version and webpack does it thing! 

  Bump into this error while trying to build a docker image via dockerfile. To resolve this, i just add a bypass proxy as shown below :-

To ensure that you can specify program argument - for example when you're writing a console app that requires command argument you can use the following settings to allow vscode + rust anaylzer pick these up during debug. Here I specify "-t www.google.com" as the argument. {     // Use IntelliSense to learn about possible attributes.     // Hover to view descriptions of existing attributes.     // For more information, visit: https://go.microsoft.com/fwlink/?linkid=830387     "version" : "0.2.0" ,     "configurations" : [         {             "type" : "lldb" ,             "request" : "launch" ,             "name" : "Debug executable 'nwt'" ,             "cargo" : {                 "args" : [                    ...

 Got this error  /Microsoft Shared/ink/en-US/micaut.dll.mui: no such file or directory while doing a docker build.  After i change to a docker windows container then it all sorted.

 For this setup, we're going to use the httpbin example that cames with istio. You can close this repo.  Basics, run the following do the setup  istioctl install --set profile =demo -y kubectl label namespace default istio-injection=enabled go into samples\httpbin directory and then run:  kubectl apply -f .\httpbin-gateway.yaml  kubectl apply -f .\httpbin.yaml If all goes well, you will be able to do load httpbin page. To apply the local rate restriction to all route, use the following yaml (ripped off from isio docs) apiVersion : networking.istio.io/v1alpha3 kind : EnvoyFilter metadata :   name : filter-local-ratelimit-svc   namespace : default spec :   workloadSelector :     labels :       app : httpbin   configPatches :     - applyTo : HTTP_FILTER       match :         context : SIDECAR_INBOUND         listener :           ...

 This is an example of using Result and operator ? in Rust.  Let's say I have the following division function  fn div ( self , x : f64 , y : f64 ) -> MathResult {         if y == 0.0 {             Err ( MathError :: DivisionByZero )         } else {             Ok ( x / y )         }     } When i call using the code here, it says " the `?` operator can only be used in a method that returns `Result` or `Option " fn op1 ( self , x : f64 , y : f64 ) {         // if `div` "fails", then `DivisionByZero` will be `return`ed         let ratio = self . div ( x , y ) ? ;         Ok ( 10.0 )     } Rightly pointed out so, if i change my function to this (that returns MathResult), then i was able to use the ? operator. fn op2 ( self , x : f64 , y : f64 ) -> Mat...

  Weird message from rust for the actual issue If i have the following code, it will trigger this error and the reason is because I didn't cover the scenarios required fn test ( self , i : u32 )   -> Result < i8 , & ' static str > {         match i {             1 => Ok ( 1 ),             2 => Ok ( 2 ),             3 => panic ! ( "oh nonono" ),         }     } So adding a _ => panic("no value") - i was able to fix it fn test ( self , i : u32 )   -> Result < i8 , & ' static str > {         match i {             1 => Ok ( 1 ),             2 => Ok ( 2 ),             3 => panic ! ( "oh nonono" ),             _ => panic ! ( "no...

  First have to install (about 1G of additional space is required)  apt-get install gcc-mingw-w64 In case you would like to cross compile your application into windows, you can do the following  rustup target add x86_64-pc-windows-gnu This will add the require component. Then run cargo build like you normally wo cargo build --release --target x86_64-pc-windows-gnu

 After trying to build my application and adding reqwest library into my cargo toml, i get the error  "failed to run custom build command for `openssl-sys v0.9.100" To resolve this  apt-get update  apt install pkg-config apt install libssl-dev And then rebuild.

 github push via https no longer support user/password. If you try to do a git push, you will be prompted for a username and password. You should be using a token - as your password. You can create classic token by going to github -> developer settings -> create token. Once you have your token, try to do another git push. Instead of entering your password, enter this token.

  Clap have the concept of  a) argument - is input pass to the executing command  for example myexec helloworld.  helloworld here is the argument b) options - predefined argument that the program accept, for example myexec -n test  You will see example below  When you work with clap derive mode, you have to create a struct that derived from Parser as shown below: Simple Argument Here we will create a command line that takes in a string as input  use std :: path :: PathBuf ; use clap :: { Parser , Subcommand }; #[ derive ( Parser )] #[ command (version, about, long_about = None )] pub struct Cli {     pub name : Option < String >, } main.rs fn main () {     use clap :: Parser ;     let cli = cmd :: Cli :: parse ();     let cli = cmd :: Cli :: parse ();     println ! ( "name: { : ? } " , cli . name . as_deref ()); } To execute, run myexec test and it will output  name: test Addi...

  Install Windows WSL subsystem for linux.  Install rust curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh Create a new application using cargo  cargo new guessing_game then fire up vscode using the following command cd guessing_game code .  Install the following extension  - rust-analyzer  - codellvm  Then with vscode, go and look for main.rs.  As you hover over the main function, there's 2 options that appears, 1. run 2. debug  You should add a breakpint and then click on debug

  When i tried running the following command (trying to install modular), I got the following error:  Then I tried to run  sudo apt-get update Solution I got another error. As you might have guessed it, this is due to 'apt-get'install issue that related to system clock. Then run the following command :- hwclock --hctosys  After that run    sudo apt-get update Once that completed, I just re-run modular cli installation again curl https://get.modular.com | sh - && \ modular auth mut_89ef4b15a38a47bf98c3e09f25241f41 You may need to run "modular auth" separately by running the following command:-  modular auth mut_89ef4b15a38a47bf98c3e09f25241f41 Then install sdk via modular install mojo
