By Paul Krill The next version of the Ruby programming language, Ruby 3.4.0, has been released in preview, bringing changes for string literals and class updates. Unveiled May 16, the Ruby 3.4.0 preview is downloadable from ruby-lang.org. With this update, string literals in files without a frozen_string_literal comment now behave as if they were frozen. If mutated, a deprecation warning is emitted. The change marks a first step toward making frozen string literals the default in Ruby. Frozen or immutable strings offer both performance and safety advantages. In other language changes, keyword ...

By Simon Bisson Some time ago I wrote about the work Microsoft was doing to improve the Azure APIs. That project delivered a set of automatically generated API definitions and SDKs, making it easier to link your applications to the cloud and to manage Azure services using code. Behind the scenes was a new language Microsoft developed called CADL, the Concise API Design Language. Building on concepts from both TypeScript and Bicep, CADL allowed you to define and describe APIs in a way that made it easy to use code to define API operations and then compile the result as an OpenAPI definition. It...

By Charly Batista In May 1974, Donald Chamberlin and Raymond Boyce published a paper on SEQUEL, a structured query language that could be used to manage and sort data. After a change in title due to another company’s copyright on the word SEQUEL, Structured Query Language (SQL) was taken up by database companies like Oracle alongside their new-fangled relational database products later in the 1970s. The rest, as they say, is history. SQL is now 50 years old. SQL was designed and then adopted around databases, and it has continued to grow and develop as a way to manage and interact with data. A...

By Matthew Tyson Research suggests there are seven JavaScript language elements developers lookup more than any other. While you might not be able to write a complete JavaScript program using only these features, you most certainly won't get far without them. Beginners need to learn them, but they're also great brain refreshers for JavaScript veterans. Let’s take a look at the JavaScript language features every developer needs. The 'most searched' JavaScript language elementsarray: Storing collectionsCollections of values are an essential aspect of all programming languages. In JavaScript, we ...

By Paul Krill Fortran’s return to the top 10 in Tiobe’s monthly index of language popularity is being attributed to the growing importance of numerical or mathematical computing. Fortran returned to the top 10 in the index for April 2024 and retains the 10th place in the index for May 2024. The rating for Fortran did slip a bit, from 1.47% last month to 1.24% this month. But before April, Fortran’s last appearance in the Tiobe top 10 was April 2002. Paul Jansen, CEO of Tiobe, a provider of tools for measuring software quality, attributed Fortran’s recent rise to the language’s advantages for n...

By Paul Krill Rust 1.78, just released as the latest version of the popular, memory-safe programming language, adds backing for a #[diagnostic] attribute namespace to influence compiler messages. These messages are treated as hints that the compiler is not required to use, the Rust team said. Also it is not an error to provide a diagnostic that the compiler does not recognize. The feature is designed to allow source code to provide diagnostics even when they are not supported by all compilers. Announced May 2, Rust 1.78 can be installed via rustup: $ rustup update stable Another feature in Rus...

By Paul Krill Microsoft has introduced TypeSpec, a language for API-centric development. Unveiled April 25, TypeSpec is designed to meet the needs of API developers, managers, and architects in an environment where delivering high-quality APIs and related experiences has become increasingly critical and complex, Microsoft said. The company described TypeSpec as a lightweight language that describes APIs using any protocol or serialization format and encapsulates common data types, API patterns, and API guidelines into high level, reusable components. It can define complex data and API shapes w...
