How does SSL works?


1.      A browser or server attempts to connect to a Website. Web server, secured with SSL. 

2.      The browser/server requests that the Web server identify itself.

  1. The Web server sends the browser/server a copy of its SSL certificate and Public Key

4.      Web Brower has list of trusted certificate authorities

5.      Web server responds by sending a certificate. Server responds by sending a copy of its SSL Certificate, including the server's public key.

6.      Web browser checks the certificate and verify whether the certificate is issued by one of it’s trusted security certificate authorities.

  1. The browser/server checks to see whether or not it trusts the SSL certificate. If so, it sends a message to the Web server.
  2. The Web server sends back a digitally signed acknowledgement to start an SSL encrypted session.
  3. Encrypted data is shared between the browser/server and the Web server.

10.  If everything are fine, then browser generates a random symmetric key

11.  Then use the Public Key shared by the SSL to encrypt the data. The session key is used to encrypt all transmitted data after the secure connection is made,

12.  Web server decrypt the data using the it’s own Private key

What is the difference between Elastic and Enterprise Redis w.r.t "Hybrid Query" capabilities

  We'll explore scenarios involving nested queries, aggregations, custom scoring, and hybrid queries that combine multiple search criteria. 1. Nested Queries ElasticSearch Example: ElasticSearch supports nested documents, which allows for querying on nested fields with complex conditions. Query: Find products where the product has a review with a rating of 5 and the review text contains "excellent". { "query": { "nested": { "path": "reviews", "query": { "bool": { "must": [ { "match": { "reviews.rating": 5 } }, { "match": { "reviews.text": "excellent" } } ] } } } } } Redis Limitation: Redis does not support nested documents natively. While you can store nested structures in JSON documents using the RedisJSON module, querying these nested structures with complex condi...

How are vector databases used?

  Vector Databases Usage: Typically used for vector search use cases such as visual, semantic, and multimodal search. More recently, they are paired with generative AI text models for conversational search experiences. Development Process: Begins with building an embedding model designed to encode a corpus (e.g., product images) into vectors. The data import process is referred to as data hydration. Application Development: Application developers utilize the database to search for similar products. This involves encoding a product image and using the vector to query for similar images. k-Nearest Neighbor (k-NN) Indexes: Within the model, k-nearest neighbor (k-NN) indexes facilitate efficient retrieval of vectors. A distance function like cosine is applied to rank results by similarity.

Feature Engineering - What and Why

Feature engineering is a crucial step in the machine learning pipeline where you create new, meaningful features or transform existing features to improve the performance of your predictive models. It involves selecting, modifying, or creating features from your raw data to make it more suitable for machine learning algorithms. Here's a more detailed overview of feature engineering: Why Feature Engineering? Feature engineering is essential for several reasons: Improving Model Performance: Well-engineered features can significantly boost the predictive power of your machine learning models. Handling Raw Data: Raw data often contains noise, missing values, and irrelevant information. Feature engineering helps in cleaning and preparing the data for analysis. Capturing Domain Knowledge: Domain-specific insights can be incorporated into feature creation to make the model more representative of the problem. Common Techniques and Strategies: 1. Feature Extraction: Transforming raw data...
