  • ROOT Package Management: “Lazy Install” Approach
    ROOT package management: “lazy install” approach Oksana Shadura ROOT Monday meeting Outline ● How we can improve artifact management (“lazy-install”) system for ROOT ● How to organise dependency management for ROOT ● Improvements to ROOT CMake build system ● Use cases for installing artifacts in the same ROOT session Goals ● Familiarize ROOT team with our planned work ● Explain key misunderstandings ● Give a technical overview of root-get ● Explain how root-get and cmake can work in synergy Non Goals We are not planning to replace CMake No change to the default build system of ROOT No duplication of functionality We are planning to “fill empty holes” for CMake General overview Manifest - why we need it? ● Easy to write ● Easy to parse, while CMakeLists.txt is impossible to parse ● Collect information from ROOT’s dependencies + from “builtin dependencies” + OS dependencies + external packages to be plugged in ROOT (to be resolved after using DAG) ● It can be easily exported back as a CMakeLists.txt ● It can have extra data elements [not only what is in CMakeLists.txt, but store extra info] ○ Dependencies description (github links, semantic versioning) ■ url: "ssh://[email protected]/Greeter.git", ■ versions: Version(1,0,0)..<Version(2,0,0) Manifest is a “dump” of status of build system (BS), where root-get is just a helper for BS Manifest - Sample Usage scenarios and benefits of manifest files: LLVM/Clang LLVM use CMake as a LLVMBuild utility that organize LLVM in a hierarchy of manifest files of components to be used by build system llvm-build, that is responsible for loading, verifying, and manipulating the project's component data.

  • Developing Ios Applications with Rubymotion
    Developing iOS Applications With RubyMotion Matias Korhonen Bachelor’s Thesis Degree Programme in Business Information Technology 2013 Abstract 01 December 2013 Degree Programme in Business Information Technology Author Year of entry Matias Korhonen 2008 Title of report Number of report and Developing iOS Applications With RubyMotion attachment pages 50 + 22 Advisor Juhani Välimäki Users are spending an ever larger amount of time using smartphones and other mo- bile devices. Users are more willing than ever to both buy apps for these devices and more willing to buy other products using these devices. Until recently, it has not been possible to use the Ruby language to create applica- tions for any popular smartphone platforms. However, this has relatively recently changed with the introduction of Ruboto for Android and RubyMotion for iOS de- velopment. The purpose of this thesis project was to investigate the development of iOS applica- tions in RubyMotion. RubyMotion is a toolchain that enables the development of iOS and OS X applications using the Ruby programming language. RubyMotion ap- plications can use all the same features that are available to regular, Objective-C based applications. Developers can also use 3rd party Objective-C libraries in their RubyMotion applications. The thesis indicated that RubyMotion is a viable option for developers with prior ex- perience in either Ruby or with iOS application development (or both). Nevertheless, at this point, RubyMotion does not seem like a language that should be recom- mended to novice developers as the mix of Ruby and the iOS SDK can be confusing at times.

  • The Developer Factor in Software Privacy
    The Developer Factor in Software Privacy Mohammad Tahaei Doctor of Philosophy School of Informatics University of Edinburgh 2021 Abstract Computer programming operates and controls our personal devices, cars, and infrastructures. These programs are written by software developers who use tools, software development platforms, and online resources to build systems used by billions of people. As we move towards societies that rely on computer programs, the need for private and secure systems increases. Developers, the workforce behind the data economy, impact these systems’ privacy, and consequently, the users and society. Therefore, understanding the developer factor in software privacy provides invaluable inputs to software companies, regulators, and tool builders. This thesis includes six research papers that look at the developer factor in software privacy. We find that developers impact software privacy and are also influenced by external entities such as tools, platforms, academia, and regulators. For example, changes in regulations create challenges and hurdles for developers, such as creating privacy policies, managing permissions, and keeping user data private and secure. Developers interactions with tools and software development platforms, shape their understanding of what privacy means, such as consent and access control. Presentation of privacy information and options on platforms also heavily impact developers’ decisions for their users’ privacy, and platforms may sometimes nudge developers into sharing more of their users’ data by using design (dark) patterns. Other places developers learn about privacy include universities, though they may not learn how to include privacy in software. Some organisations are making efforts to champion privacy as a concept inside development teams, and we find that this direction shows promise as it gives developers direct access to a champion who cares about privacy.
