Approximate Nearest Neighbor (ANN) search is fundamental for many modern applications,from recommendation systems to generative AI.When dealing with millions or billions of high-dimensional vectors,exact search becomes computationally infeasible.This is wh...
The concept of "default timeout" for Amazon Bedrock invoke_model primarily refers to the client-side timeout of the AWS SDKs (like Boto3) or the AWS CLI,rather than a configurable service-side timeout on Bedrock itself.Bedrock will process your request unt...
When you encounter a 504 Gateway Timeout,systematically investigate each of these areas.Start with the most likely causes (request timeouts,Bedrock status) and then move on to more complex issues like network connectivity or load balancer configuration.Imp...
When you use Claude via Bedrock: it has a prompt size limit,typically around 5,000 bytes for some models (Claude 1 / 2).Exceeding that triggers errors.Here’s how you can handle it: .1.Chunking / Splitting the InputBreak your large prompt into smaller pi...
One of the rising area regarding smart search is to use Vector Database stored in S3 with Amazon Bedrock so you can use it for retrieval-augmented generation (RAG) or semantic search.Amazon Bedrock is a fully managed service that allows developers to acces...

The time () function generates a long string of numbers representing how many seconds have passed since January 1, 1970. It is possible to add and subtract time by adding and subtracting seconds.
The three most basic searches using regular expressions are searching for the strings start, the strings end, or for characters it contains. We can do these using the following symbols:^ indicates the string starts with the specified characters, so "^strcp...
This source code describes how to send email with php with headers .
This code prints array count values
See below as calculator with basic four functions.
In this article we'll make number format like 0001, 0002, 0003 in stead of 1, 2 ,3. It's very easy to do this for your counter, category or product ID. etc.
This basically randomly pick a number between the min and max values. This is made because the rand() and mt_rand() function can not accept numbers larger than 2^31 or 2^63,depend on your processor and complier.
