The article emphasizes the importance of approaching problems without relying on machine learning (ML) as a first step. It highlights that successful implementation of ML requires data, a solid pipeline, and high-quality labels, making preliminary solutions often more effective without it. Key takeaways include: 1. **Rule #1**: Don't hesitate to launch a product without using ML. Initial solutions can often be derived from simpler heuristics rather than complex models. 2. **Expert Consensus**: Several machine learning practitioners agree that

The author addresses Oracle regarding the JavaScript trademark, claiming that Oracle has abandoned it, leading to confusion in the developer community. JavaScript is now a widely used programming language that many do not realize is trademarked by Oracle. The author argues that this trademark fits the legal definition of abandonment, as it has not been actively used in any Oracle products. The history of the trademark dates back to 1995 when it was created by Netscape and later acquired by Oracle through its purchase of Sun Microsystems in

The article discusses the pitfalls of excessive collaboration within Agile and Kanban methodologies. While collaboration is often praised for enhancing delivery speed, customer satisfaction, and team engagement, it is frequently applied in the wrong context. Many teams prioritize internal collaboration over effective communication with customers, leading to a culture that overlooks the reasons behind collaboration needs. This overemphasis on collaboration acts as a temporary fix for dependency-related issues without addressing deeper problems such as slow handoffs or inadequate approvals. As collaboration becomes the default approach for

Recent advancements in weather forecasting have seen significant improvements, particularly with the emergence of deep learning technology. Traditional forecasting accuracy has improved at a rate of one additional day of skill every decade; however, recent developments using GPUs and deep learning have accelerated this progress. Companies like NVIDIA, Google DeepMind, Huawei, and Microsoft have been researching deep learning models that predict weather using data rather than relying heavily on atmospheric physics, yielding better results than conventional methods. Notably, the ClimaX and Aurora projects at Microsoft

The author discusses their coding projects primarily involving Ruby and C, focusing on electronics and hardware. Following their previous testing of Ruby with YJIT against C for bit-banging I2C, they have decided to implement bit-bang SPI in Ruby, while considering how to compare it to a C implementation without writing one. They noted that SPI is similarly structured to I2C for benchmarking their OLED. An optimization was made to the I2C implementation, which involved saving the state of the SDA pin

Programming has become increasingly stressful, especially compared to the 90s and early 2000s. While previous pressures were tied to specific deadlines, today's environment feels constantly stressful, which affects both health and productivity. The author attributes this heightened stress to a shift from longer project timelines to working in sprints—shorter, repetitive deadlines that create continuous pressure. Unlike the Waterfall model, which had natural breaks between projects, sprints lack downtime and leave no opportunity to recover, leading to chronic stress for

The author discusses the design principles of separating private and public behaviors in code but acknowledges the potential pitfalls of this binary perspective. They illustrate their point using a code example involving a `Rental` class that manages transactions between a lender and a borrower. The method `Rental#transactions` checks whether the instance variable `@transactions` is populated and either returns its content or computes the necessary transactions. The issue arises when considering the implications of exposing a private method, `Rental#debit_transactions`, to the
