Bazel (software)
Bazel () is a free software tool used for the automation of building and testing software. The company Google uses the build tool ''Blaze'' internally and released an open-sourced port of the Blaze tool as Bazel, named as an anagram of Blaze. Bazel was first released in March 2015 and achieved beta status by September 2015. Similar to building tools like Make, Apache Ant, or Apache Maven, Bazel builds software applications from source code using a set of rules. Rules and macros are created in the Starlark language (previously called Skylark), a dialect of Python. There are built-in rules for building software written in the programming languages of Java, C, C++, Go, Python, Objective-C, and Bourne shell scripts. Bazel can produce software application packages suitable for deployment for the Android and iOS operating systems. Rationale One of the goals of Bazel is to create a build system where build target inputs and outputs are fully specified and therefore precisely known ...

Cryptographic Hash Function
A cryptographic hash function (CHF) is a hash algorithm (a map of an arbitrary binary string to a binary string with fixed size of n bits) that has special properties desirable for cryptography: * the probability of a particular n-bit output result (hash value) for a random input string ("message") is 2^ (like for any good hash), so the hash value can be used as a representative of the message; * finding an input string that matches a given hash value (a ''pre-image'') is unfeasible, unless the value is selected from a known pre-calculated dictionary (" rainbow table"). The ''resistance'' to such search is quantified as security strength, a cryptographic hash with n bits of hash value is expected to have a ''preimage resistance'' strength of n bits. A ''second preimage'' resistance strength, with the same expectations, refers to a similar problem of finding a second message that matches the given hash value when one message is already known; * finding any pair of different messa ...

Compiling Tools
In computing, a compiler is a computer program that translates computer code written in one programming language (the ''source'' language) into another language (the ''target'' language). The name "compiler" is primarily used for programs that translate source code from a high-level programming language to a low-level programming language (e.g. assembly language, object code, or machine code) to create an executable program. Compilers: Principles, Techniques, and Tools by Alfred V. Aho, Ravi Sethi, Jeffrey D. Ullman - Second Edition, 2007 There are many different types of compilers which produce output in different useful forms. A ''cross-compiler'' produces code for a different CPU or operating system than the one on which the cross-compiler itself runs. A ''bootstrap compiler'' is often a temporary compiler, used for compiling a more permanent or better optimised compiler for a language. Related software include, a program that translates from a low-level language to a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monorepo
In version-control systems, a monorepo ("mono" meaning 'single' and "repo" being short for 'repository') is a software-development strategy in which the code for a number of projects is stored in the same repository. This practice dates back to at least the early 2000s, when it was commonly called a shared codebase. Google, Meta, Microsoft, Uber, Airbnb, and Twitter all employ very large monorepos with varying strategies to scale build systems and version control software with a large volume of code and daily changes. A related concept is the monolithic application, but whereas a monolith combines its sub-projects into one large project, a monorepo may contain multiple independent projects. Advantages There are a number of potential advantages to a monorepo over individual repositories: ; Ease of code reuse : Similar functionality or communication protocols can be abstracted into shared libraries and directly included by projects, without the need of a dependency package mana ...

Bazel Logo
Bazel is a village in Belgium, in the municipality of Kruibeke in the province of East Flanders. The village is home to the Wissekerke Castle. The municipality of Bazel merged into Kruibeke in 1977. Overview The parish church was founded in the early 10th century. The village was located on the medieval road from Lille to Antwerp. From 1640, the village started develop. The Wissekerke Castle is located in the village. The castle originates from the 10th century, however it burnt down, and was rebuilt in the 15th century. For two centuries, it was owned by the Vilain XIIII Vilain and Vilain XIIII (pronounced ''Vilain-Quatorze'' , sometimes written with the more standard Roman numerals Vilain XIV) is a Belgian noble family. Their coat of arms is basically "Sable, a chief argent" (french: sable, au chef d'argent), a ... family, who remodelled the castle in neo-Gothic style.

Buck (software)
Buck is a multi-language build system developed and used by Meta Platforms, Inc. It was designed for building small, reusable modules consisting of code and resources within a monorepo. It supports C++ (Objective-C, Swift), Shell, Java ( Kotlin, Groovy), Python, Lua, OCaml, Rust, Go and other languages as source code input. It can produce binary outputs for a variety of target platforms including IOS, Android, .NET and Java VM runtimes. Buck is licensed under the Apache License 2.0. Buck requires the explicit declaration of dependencies and enforces this using a symbolic link tree. Because all dependencies are explicit and Buck has a directed acyclic graph of all source files and build targets, Buck can perform incremental recompilation, only rebuilding targets downstream of files that have changed. Buck computes a key for each target that is a hash of the contents of the files it depends on. It stores a mapping from that key to the build target in a build cache. If targets ...

Scala (programming Language)
Scala ( ) is a strong statically typed general-purpose programming language that supports both object-oriented programming and functional programming. Designed to be concise, many of Scala's design decisions are aimed to address criticisms of Java. Scala source code can be compiled to Java bytecode and run on a Java virtual machine (JVM). Scala can also be compiled to JavaScript to run in a browser, or directly to a native executable. On the JVM Scala provides language interoperability with Java so that libraries written in either language may be referenced directly in Scala or Java code. Like Java, Scala is object-oriented, and uses a syntax termed '' curly-brace'' which is similar to the language C. Since Scala 3, there is also an option to use the off-side rule (indenting) to structure blocks, and its use is advised. Martin Odersky has said that this turned out to be the most productive change introduced in Scala 3. Unlike Java, Scala has many features of functional prog ...

Sbt (software)
sbt is an open-source build tool for Scala and Java projects, similar to Apache's Maven and Gradle. Its main features are: *Native support for compiling Scala code and integrating with many Scala test frameworks *Continuous compilation, testing, and deployment *Incremental testing and compilation, meaning only changed sources are re-compiled, only affected tests are re-run *Build descriptions written in Scala using a DSL *Dependency management using Coursier, which supports Maven-format repositories *Integration with the Scala REPL for rapid iteration and debugging *Support for mixed Scala/Java projects sbt is the ''de facto'' build tool in the Scala community, used, for example, by Play Framework. Lightbend Inc., which managed sbt development in past years, has called sbt "arguably the best tool for building Scala projects", saying that its two most prominent features are incremental compilation and an interactive shell. In continuous compilation mode, the Scala compi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Clojure
Clojure (, like ''closure'') is a dynamic and functional dialect of the Lisp programming language on the Java platform. Like other Lisp dialects, Clojure treats code as data and has a Lisp macro system. The current development process is community-driven, overseen by Rich Hickey as its benevolent dictator for life (BDFL). Clojure advocates immutability and immutable data structures and encourages programmers to be explicit about managing identity and its states. This focus on programming with immutable values and explicit progression-of-time constructs is intended to facilitate developing more robust, especially concurrent, programs that are simple and fast. While its type system is entirely dynamic, recent efforts have also sought the implementation of a dependent type system. History and development process Rich Hickey is the creator of the Clojure language. Before Clojure, he developed dotLisp, a similar project based on the .NET platform, and three earlier attempts ...
