The post discusses the importance of API versioning strategies for maintaining stability and predictability as systems evolve. It highlights that while creating APIs is straightforward, managing changes becomes challenging due to the reliance of API consumers on stable contracts. Even minor modifications, such as renaming fields or changing formats, can disrupt integrations. Versioning allows for clear communication of changes, enabling consumers to transition to new versions smoothly. The post introduces guest author Irina Dominte, a software architect and Microsoft MVP with expertise in distributed systems

In a recent analysis, Andrew Churchill highlights a significant observation from interviewing 134 engineers: many companies overlook talented junior engineers while competing heavily for senior-level candidates. He argues that smart companies can gain a competitive edge by hiring juniors, especially as many "experienced" hires may not be substantially more productive than well-mentored juniors. Despite common excuses from different company sizes regarding the hiring of juniors—such as the need for immediate productivity or handling complex systems—Churchill points out that the core attributes of motivation

The content discusses the underrated capabilities of C#, particularly its ability to support low-level programming. While C# is well-known for its versatility in creating a variety of applications (mobile, desktop, games, websites, etc.), it also allows for low-level, unsafe code that bypasses features like garbage collection and bounds-checking. This low-level coding can enhance performance and interoperability with C libraries or the operating system by eliminating runtime checks on memory accesses. The author explains that bounds-checking in C#

Laboratory.love is a platform that allows consumers to crowdfund independent testing of food products for harmful substances, especially plastic chemicals and endocrine disruptors. It emerged in response to concerns highlighted by PlasticList, which revealed that 86% of food products tested contained plastic chemicals, including all baby food samples. While the EU has significantly lowered limits for BPA, the FDA's standards remain much higher, indicating a regulatory disparity. The platform operates similarly to a mix of Consumer Reports and Kickstarter. Users can

In the late 1990s, Intel was focused on its Itanium (IA-64) architecture as the future of 64-bit processing. However, some cautious engineers secretly developed a 64-bit extension for x86 processors, which was not released due to a marketing decision. Intel chose to "fuse off" this feature to avoid undermining Itanium's prospects. In contrast, AMD announced its 64-bit extension, AMD64, in 1999 and launched it in 200
