# Switch terminal architecture type:
alias x86="$env /usr/bin/arch -x86_64 /bin/zsh ---login"
alias arm="$env /usr/bin/arch -arm64 /bin/zsh ---login"

This will allow you to quickly change architecture runtimes in your processor between arm64 (native) and i386 (rosetta), like this:

cost is very high if it is micro service,

each service is required to be sepearted ALB

the cost will be very high

common solution is to make ALB reusuable

yet it is not an valid option

Create option to reuse an existing ALB instead of creating a new ALB per Ingress · Issue #298 · kubernetes-sigs/aws-alb-ingress-controller

the only solution is

jakubkulhan/ingress-merge

this solution is use differnt url route in same alb

yet the url rewrite is not ready yet

URL rewrite? · Issue #835 · kubernetes-sigs/aws-alb-ingress-controller

a lot of closed/reopend issues they dun have any plan to make it ready

A lot of people uses Terraform as standard and you are saying to all the terraform users that they are out of luck. Do you realize the number of customers you are saying you do not care about and your tool is useless to them. Terraform is the leading IAC tool. What good is a tool if more than half of your potential user base cannot use it because of a design decision? I think just closing this and ignoring a large customer base is short sighted and foolish.

Today I ran into this- I’m using terraform as well, but the instructions for deploying an ALB Ingress Controller assume you’ve used eksctl. This command gives me an error-

it is very common to use terraform for IAC, man. AWS you made me feel very disappointed

Object Oriented Design:

You should have a working knowledge of a few common and useful design patterns (singleton, factory, adapter, bridge, visitor, command, proxy, observer, etc.) as well as know how to write software in an object oriented way with appropriate use of inheritance and aggregation.

find the greatest index of repeated number in an input array, else return -1

getLast = (input)=> {

counter = {};

for (let i = 0; i < input.length; i++) {
const index = i;
if (counter[input[i]]) {
counter[ input[i]] = {
count: counter[input[i]].count + 1,
lastIndex: i,
};
} else {
counter[ input[i]] = {
count: 1,
lastIndex: i,
};
}
}


console.log(counter);
let result = -1;
for (k in counter) {
if (counter[k].count > 1 && counter[k].lastIndex > result){
result = counter[k].lastIndex;
}
}

return result;
}`

other question:

foo= [1,2] . foo[8] =1 ; foo.legnth = ?

difference between undefinied and null?

I hope aws could provide better tutorial like above.

Architecture
In this first portion of the interview, we will ask you to create and iterate on a design
for this system. As we introduce new requirements, the design will evolve.
During the interview we will use https://sketchboard.me/ to sketch the problem
and solution. You will receive a unique link prior to the interview. In the meantime,
please play around with sketchboard to get familiarized with its functionality and
features.
Tip: Keep it simple!
Coding
Some time before your interview, we will send you a small but fully functional
project. To save time, we ask that you please make sure you are able to run the
project before the interview. If you have any issues, get back to the person that sent
you the project, and we will help you out.

During the interview, we will work together to add some additional functionality to
this project.
Tip: The project may not be a real product, but we still want it to be production
ready.

Both are quite difficult to me. sketchboard part requirement is very unclear. the expectation is more than this. and I think this is not simple. What is the meaning of keep it simple? I think answering vague question is not easy.

The Architecture Interview - Susan Fowler

coding part require exp in TDD, protocol. TDD is my weakness part which is trivial when you work in Hong Kong.

good experience anyway. but the interviewer needs to make better descriptions for the tasks. And I should prepare better for handling vague questions: keep ask proper questions for clarifications
