whitepaper | The Ambients protocol white paper | Architecture library

The thing I'm trying is a multipage react app where I can navigate between pages(like from the main route '/' to '/whitepape' or 'privacyPolicy'), but I have 4 different routes('/', 'services', 'features', 'contactUs') within the main route '/' which use react-scroll to get the scrolling between those 4 components whose links are added in the Navbar(this part works as expected).

But navigating between pages like replacing entirely all 4 components with whitepaper page or privacyPolicy page, with Navbar and Footer at the same place so that I can navigate back to home.

This is what I’m stuck at any help is appreciated I’m not sure I’m following the right way to implement what I need. I have been using React Navigation in react native which is simple to understand and straightforward, wish react-router was so straight forward instead react-router is a bit confusing.

Can anyone tell me why this function is not giving me the desired results. Have I missed something obvious? When I console log

I am trying to implement a green/blue AWS deploy of static files backed by S3 according to this (oldish) whitepaper.

In short, the idea is to create two separate CloudFront distributions which point to two separate folders in an S3 bucket. One is "green" and one "blue". After deploying one or the other, you then switch traffic over from green to blue or vice versa using weighted routing.

That is all well and good but the problem comes with using your own domain and linking a certificate.

In order to get CloudFront to serve the S3 files properly (over https with a cert on your own domain), you need to input the FQDN in the "Alternate Domain Names (CNAMEs) field when configuring the CloudFront distribution. However you cannot use the same name in multiple Cloudfront Distributions.

Therefore, I would need to use a different url per cloudfront distribution e.g. blue.mydomain.com and green.mydomain.com

However, if I do this then using weighted routing with a single A record in the associated Route53 entry would not work as the name must match the "CNAMEs" entered in the Cloudfront distribution to prevent ssl errors. Am I missing something? I could add my own reverse proxy or something but I really don't want to do that.

TL;DR it seems like this whitepaper is impossible to implement as-is?

I'm migrating from an architecture that I have a Lambda inside a Private Subnet, talking with a Public Subnet that has a NatGateway, triggered by an API Gateway WebSocket. And now I removed the Nat Gateway and inserted a VPC Endpoint with a VPC Link. That I found in the link: https://d1.awsstatic.com/whitepapers/private-api-best-practices.pdf

My VPC endpoint is currently with a policy all open, I didn't use the Enable Private DNS Name , because in my VPC there are another projects that talk with API Gateway.

My API Gateway triggered the Lambda, but could not respond to the return message. My lambda has a timeout.

In my older architecture, my return endpoint was https://{restapi-id}.execute-api.{region}.amazonaws.com/{stage}, and now when I try to respond, it doesn't work with that endpoint.

Do I have to change the Endpoint?

My Security Group and NACL are very open until I finish testing this connection. The VPC Link and the API Gateway Endpoint are configured with the Lambda Subnet and the Lambda Security Group.

Is something missing from VPC Link or VPC Endpoint?

Edit: I activated the log in the ApiGateway, and before the lambda logs it returns:

The version compatibility of Vulkan SDK is documented in LunarG's whitepaper, but I'd like to know whether those extensions controlled by the flags listed below are following the same rule as well.

I have a question about when it makes sense to use a Redis cluster versus standalone Redis.

Suppose one has a real-time gaming application that will allow multiple instances of the game and wish to implement real time leaderboard for each instance. (Games are created by communities of users).

Suppose at any time we have say 100 simultaneous matches running.

Based on the use cases outlined here :

https://d0.awsstatic.com/whitepapers/performance-at-scale-with-amazon-elasticache.pdf

https://redislabs.com/solutions/use-cases/leaderboards/

https://aws.amazon.com/blogs/database/building-a-real-time-gaming-leaderboard-with-amazon-elasticache-for-redis/

We can implement each leaderboard using a Sorted Set dataset in memory.

Now I would like to implement some sort of persistence where leaderboard state is saved at the end of each game as a snapshot. Thus each of these independent Sorted Sets are saved as a snapshot file.

I have a question about design choices:

1. Would a redis cluster make sense for this scenario ? Or would it make more sense to have standalone redis instances and create a new database for each game ?

As far as I know there is only a single database 0 for a single redis cluster.(https://redis.io/topics/cluster-spec) In that case, how would one be able to snapshot datasets for each leaderboard at different times work ?

https://redis.io/topics/cluster-spec

From what I can see using a Redis cluster only makes sense for large-scale monolithic applications and may not be the best approach for the scenario described above. Is that the case ?

Or if one goes with AWS Elasticache for Redis Cluster mode can I configure snapshotting for individual datasets ?

I have been using iText (on .Net) for some time but have only recently started using htmlpdf instead of building the document manually.

In previous projects I used the following code to set the document metadata:

Whether PROC IMPORT using xlsx engine in SAS scans all rows to get variables' length? I have a whitepaper documented that xlsx engine will scan all the row to get datatype but no paper so far confirm that SAS will also scan all rows to get variables' length.

Currently i try to verify the Bitcoin Block 77504 by my own. But from the satoshi whitepaper it seems i have more questions than answer to do so.
