Speeding up Ruby by rewriting C… in Ruby – by JP Camara
The article compares the performance of various programming languages, revealing that Ruby’s main implementation, CRuby, ranks as the third slowest, outperforming R and Python. Benchmarks show Ruby’s performance is poor for the Fibonacci test. The article also discusses the impact of YJIT on Ruby’s performance, highlighting its limitations due to core Ruby methods being implemented in C.
Understanding the Event Loop and Async Programming in Node.js
Node.js is renowned for its efficiency and scalability due to its non-blocking, asynchronous architecture powered by the event loop. This allows for multiple tasks to be handled on a single thread, ensuring the main thread remains responsive. However, asynchronous programming can present challenges like "callback hell". Check it out to know more.
Is Aurora DSQL your next database? – by Paul Planchon
Amazon introduced Aurora DSQL, a serverless, globally distributed database, at Re:Invent 2024. It offers high availability, multi-regional support, and PostgreSQL compatibility, but is still in its early stages and lacks PostgreSQL features. The unique authentication method requires a URL-like token, posing challenges for integration. Despite its promise, Aurora DSQL is not yet ready for widespread adoption due to its limited features and awkward authentication methods.
SQL best practices – don’t compare count(*) with 0 – by Hubert depesz Lubaczewski
The article discusses a common SQL mistake: using COUNT(*) to check if a user has zero addresses. Instead, it recommends using EXISTS clause for more efficiency. The article emphasizes the importance of following best practices and discussing alternative approaches like LEFT JOIN.
