To address these, it implemented prioritized queues, asynchronous database writes, and better quality of service for webhooks. The company prioritized notifications based on customer response times.
A random eviction policy performs surprisingly well for large caches. It often outperforms LRU in terms of miss rate, especially when cache size increases. This may mean that different approaches may suit different cache levels. Combining LRU for smaller caches and 2-random for larger ones might be promising. The “random” principle applies to various scenarios beyond cache eviction, like load balancing and data distribution.
With incremental static regeneration (ISR), Next.js enables the pre-rendering of pages containing dynamic data during the build time. This article is a comprehensive guide on enabling partial pre-rendering in Next.js 14, which lets you control which parts of a page are pre-rendered.
This author built a successful event/ticket service for comics by prioritizing customer feedback over assumptions.

The Split Diff view was launched on GitHub back in 2014. The engineer who shipped it is now looking to ship a new way to review diffs: blended diffs. Instead of showing 2 lines of changes for a single line change (one for the deleted line and one for the added line), blended diffs show the final file view and use AI to generate diff summaries. This article is an interesting read on how a team found a problem, designed a solution, went through design iterations, and implemented the solution with a team of engineers.
For open source to be more sustainable, companies need to contribute more to open source contributors through financial support. Today, most open source contributors need to spend extra time on securing sponsorship or taking on extra work to support themselves. Open source maintainers often burn out as a result, leading to a lower velocity of improvement on open source software.
QR codes have different parts, like finder patterns, separators, timing patterns, and format information. Mask patterns hide data and improve readability. Encoding modes specify how data is stored (e.g., numeric or alphanumeric). To decode a QR code, one can use a cheat sheet to identify the mask pattern, read the encoding mode, follow the reading order, find the total number of content bytes, and decode the content using a table. This guide takes readers through this process step-by-step with visuals.
