DuckDB v1.4 introduces database encryption capabilities, enhancing data security for users. This update allows for the encryption of sensitive datasets, which is essential for compliance with standards like SOC 2. Despite the availability of strong encryption tools and libraries, many databases, including PostgreSQL and SQLite, have limited encryption options. DuckDB previously supported Parquet Modular Encryption for encrypted columns in Parquet files but lacked comprehensive support for in-database encryption. The blog elaborates on the implementation and performance implications of the

The author presents a perspective on programming that focuses on two intrinsic forces: minimizing redundancy and minimizing dependencies. They argue that good programming practices aim to reduce both, and the quality of a programmer can often be assessed by their attitude towards these concepts. Good programmers dislike redundancy and dependencies, while bad ones tend to be indifferent to them. The main discussion revolves around the challenge of code reuse across module boundaries, particularly when minimizing redundancy conflicts with minimizing dependencies. The author notes the ambiguity of the term "module" but

The blog post discusses the significance of the game Zork, highlighting its innovative approach to gameplay through the use of the Z-Machine, a custom-built virtual machine. This technology allowed Zork to be intermediately split into three separate games (Zork I, II, and III) to accommodate the limitations of early home computers, making it one of the first truly cross-platform games. The post emphasizes the importance of game preservation, not just for play but for research purposes. It mentions that, in

The latest news highlights an upcoming study from the University of Chicago, indicating that AI coding agents, particularly Cursor, significantly boost developer productivity. The study analyzed over 1,000 organizations and found that companies using Cursor's AI tool could merge 39% more pull requests compared to those not using it, with a 25% increase in weekly code merges. Importantly, this increase in productivity did not lead to a rise in short-run revert rates, suggesting that the quality of the code produced was high

The author takes feedback seriously and has created a simple 32-bit floating-point implementation due to dissatisfaction with existing soft floating-point libraries, which are often complex and poorly documented. Their project aims for readability and simplicity rather than efficiency, exemplified through its use in a raytracer for a personal TinyCompiler project. The motivation arose from a need to emulate floating-point operations with integer arithmetic, leading to the realization that much misinformation exists on the topic. The author has developed an unoptimized C++ library for

The Pareto Principle, or the 80/20 rule, posits that 80% of results typically come from 20% of inputs. This observation, first noted by Italian economist Vilfredo Pareto in the 19th century, highlights how a small portion of efforts or resources often leads to the majority of outcomes. Understanding which 20% of activities, clients, or issues drive significant results can enhance planning, prioritization, and focus. To leverage this principle, one should list

The article argues that Perl is not dead, as demonstrated by the 2023 cpan Report, which shows its popularity remains on par with the dotcom era and even saw a slight increase after 2022. While cpan usage isn't a perfect measure, it indicates Perl’s ongoing relevance, although fewer newcomers are adopting the language since 2011. The author refutes the idea that Raku (formerly Perl 6) drained Perl's momentum, suggesting that Perl's infrastructure is too entrenched
