The blog post discusses implementing order-independent keyword arguments in C++ using the proposed reflection features of C++26. The author discovered a technique while experimenting with reflection and shares it as a showcase of the potential of these new features. Despite numerous attempts over the years to introduce keyword arguments in C++ (notably addressed in EWG issue 150), none have been successful, leading to creative workarounds. One approach mentioned is the use of designated initializers introduced in C++20, which allows for

A supply chain attack targeting Go developers was discovered involving the Go Module Mirror, a service run by Google to cache open source packages. The mirror hosted a backdoored version of a popular module, boltdb-go/bolt, for over three years due to a technique called "typosquatting." This technique allows malicious files to be named similarly to legitimate ones, leading developers to accidentally download compromised versions when they mistyped package names. Although the original malicious module on GitHub was reverted to its

The discussion centers on the challenges of validation in the context of commands, particularly highlighting the tendency of some to attempt validating all aspects at once, even when they are unrelated. The article uses the analogy of a command issued by Alice to Bob, illustrating how commands can vary in clarity and execution. For example, while Bob can straightforwardly fulfill Alice's command to fetch a broom and sweep the kitchen, various obstacles like missing items or unforeseen circumstances (e.g., an already occupied floor) can impede execution.

Network Address Translation (NAT) is a method used in private networks to manage IP addresses when devices need to communicate over an IP-based network. Due to the limited number of unique IPv4 addresses, devices often share public IP addresses, leading to communication complexities. Typically, devices on a private network are assigned private IP addresses via protocols like DHCP. To access an online resource, a device uses the Domain Name System (DNS) to convert a domain name into a public IP address and sends a request

A recent article from Quanta Magazine discusses how Andrew Krapivin, a Rutgers University undergraduate, transformed the concept of hash tables through his exploration of "Tiny Pointers," which are small entities that guide to data in memory. Initially inspired by a paper he encountered in 2021, Krapivin's efforts to miniaturize these pointers led him to develop a new, faster type of hash table that enhances data organization and retrieval. Despite initial skepticism from his former professor, Martín Farach-Colton

The author is developing a startup that relies heavily on file metadata, which varies across numerous file formats and their versions. While ExifTool by Phil Harvey is considered a strong tool for managing this metadata, challenges arise since some metadata can only be extracted using operating system tools, such as macOS's `mdls`. The startup needs to extract metadata client-side during uploads to avoid post-processing overhead and to ensure the metadata is accessible to customers. However, using ExifTool presents complications due to its reliance

The content discusses the patterns of English patronymic surnames, where a person's last name indicates their father's forename. Examples include surnames like "Peters" and "Peterson," which derive from the name "Peter," and other similar forms tied to common given names like William, Richard, and Nicholas. The text highlights how these patterns allow one to infer the original forenames, even if they're less common now. It also notes that some surnames incorporate diminutive suffixes, such as
