A resilient system continues to operate successfully in the presence of failures. There are many possible failure modes, and each exercises a different aspect of resilience. The system needs to maintain a safety margin that is capable of absorbing failure via defense in depth, and failure modes need to be prioritized to take care of the most likely and highest impact risks.

Spring chickens and spring boots! One of the widely wasted resources in the world today is Memory. Due to inefficient programming, a surprising (sometimes ‘shocking’) amount of memory is wasted. We see this pattern repeated in several enterprise applications. To prove this case, we conducted a small study.

The past several years have seen increasing adoption for PostgreSQL. PostgreSQL is an amazing relational database. Feature-wise, it is up there with the best, if not the best. There are many things I love about it – PL/ PG SQL, smart defaults, replication (that actually works out of the box), and an active and vibrant open source community. However, beyond just the features, there are other important aspects of a database that need to be considered.
SQL Performance

The ROW_NUMBER window function has numerous practical applications, well beyond just the obvious ranking needs. Most of the time, when you compute row numbers, you need to compute them based on some order, and you provide the desired ordering specification in the function's window order clause. However, there are cases where you need to compute row numbers in no particular order; in other words, based on nondeterministic order.

For the inaugural O’Reilly survey on serverless architecture adoption, we were pleasantly surprised at the high level of response: more than 1,500 respondents from a wide range of locations, companies, and industries participated. The high response rate tells us that serverless is garnering significant mindshare in the community. 1. Key findings from the survey include: 40% of respondents work at organizations that have adopted serverless architecture in some form or another.

Snap: a microkernel approach to host networking Marty et al., SOSP’19. This paper describes the networking stack, Snap , that has been running in production at Google for the last three years+. It’s been clear for a while that software designed explicitly for the data center environment will increasingly want/need to make different design trade-offs to e.g. general-purpose systems software that you might install on your own machines.

Make a plan. You may also like: Software Testing Life Cycle. Preparation turns big problems into little ones, and it turns bug problems into little sprints.

When it comes to error handling in the Go programming language (Golang), they can either be incredible or a miserable nightmare in terms of management. You can choose to embrace them and check if they are nil every opportunity that you have, or you can ignore them with an underscore. However, what happens in those circumstances where you didn’t even know the function returned something?
