Eagle: Tcl Implementation in C
Eagle: Tcl Implementation in C# Joe Mistachkin <[email protected]> 1. Abstract Eagle [1], Extensible Adaptable Generalized Logic Engine, is an implementation of the Tcl [2] scripting language for the Microsoft Common Language Runtime (CLR) [3]. It is designed to be a universal scripting solution for any CLR based language, and is written completely in C# [4]. Su- perficially, it is similar to Jacl [5], but it was written from scratch based on the design and imple- mentation of Tcl 8.4 [6]. It provides most of the functionality of the Tcl 8.4 interpreter while bor- rowing selected features from Tcl 8.5 [7] and the upcoming Tcl 8.6 [8] in addition to adding en- tirely new features. This paper explains how Eagle adds value to both Tcl/Tk and CLR-based applications and how it differs from other “dynamic languages” hosted by the CLR and its cousin, the Microsoft Dy- namic Language Runtime (DLR) [9]. It then describes how to use, integrate with, and extend Ea- gle effectively. It also covers some important implementation details and the overall design phi- losophy behind them. 2. Introduction This paper presents Eagle, which is an open-source [10] implementation of Tcl for the Microsoft CLR written entirely in C#. The goal of this project was to create a dynamic scripting language that could be used to automate any host application running on the CLR. 3. Rationale and Motivation Tcl makes it relatively easy to script applications written in C [11] and/or C++ [12] and so can also script applications written in many other languages (e.g. -

What you now hold in your hands is the first annual report of the GNOME Foundation, at the end of what has been an eventful year for us. Each year brings its challenges and rewards for the members of this global project. This year, many of our biggest challenges are in the legal arena. European countries have been passing laws to conform with the European Union Copyright Directive, and some, including France, have brought into law provisions which we as software developers find it hard to understand, but which appear to make much of what we do illegal. We have found our- selves in the center of patent wars as bigger companies jockey for position with offerings based on our hard work. And we are scratching our heads trying to figure out how to deal with the constraints of DRM and patents in multimedia, while still offering our users access to their media files. -

Eclipse (Software) 1 Eclipse (Software)
Eclipse (software) 1 Eclipse (software) Eclipse Screenshot of Eclipse 3.6 Developer(s) Free and open source software community Stable release 3.6.2 Helios / 25 February 2011 Preview release 3.7M6 / 10 March 2011 Development status Active Written in Java Operating system Cross-platform: Linux, Mac OS X, Solaris, Windows Platform Java SE, Standard Widget Toolkit Available in Multilingual Type Software development License Eclipse Public License Website [1] Eclipse is a multi-language software development environment comprising an integrated development environment (IDE) and an extensible plug-in system. It is written mostly in Java and can be used to develop applications in Java and, by means of various plug-ins, other programming languages including Ada, C, C++, COBOL, Perl, PHP, Python, Ruby (including Ruby on Rails framework), Scala, Clojure, and Scheme. The IDE is often called Eclipse ADT for Ada, Eclipse CDT for C/C++, Eclipse JDT for Java, and Eclipse PDT for PHP. The initial codebase originated from VisualAge.[2] In its default form it is meant for Java developers, consisting of the Java Development Tools (JDT). Users can extend its abilities by installing plug-ins written for the Eclipse software framework, such as development toolkits for other programming languages, and can write and contribute their own plug-in modules. Released under the terms of the Eclipse Public License, Eclipse is free and open source software. It was one of the first IDEs to run under GNU Classpath and it runs without issues under IcedTea. Eclipse (software) 2 Architecture Eclipse employs plug-ins in order to provide all of its functionality on top of (and including) the runtime system, in contrast to some other applications where functionality is typically hard coded. -

Fedora Core, Java™ and You
Fedora Core, Java™ and You Gary Benson Software Engineer What is Java? The word ªJavaº is used to describe three things: The Java programming language The Java virtual machine The Java platform To support Java applications Fedora needs all three. What Fedora uses: GCJ and ECJ GCJ is the core of Fedora©s Java support: GCJ includes gcj, a compiler for the Java programming language. GCJ also has a runtime and class library, collectively called libgcj. The class library is separately known as GNU Classpath. ECJ is the Eclipse Compiler for Java: GCJ©s compiler gcj is not used for ªtraditionalº Java compilation. More on that later... Why libgcj? There are many free Java Virtual machines: Cacao, IKVM, JamVM, Jikes RVM, Kaffe, libgcj, Sable VM, ... There are two main reasons Fedora uses libgcj: Availability on many platforms. Ability to use precompiled native code. GNU Classpath Free core class library for Java virtual machines and compilers. The JPackage Project A collection of some 1,600 Java software packages for Linux: Distribution-agnostic RPM packages. Both runtimes/development kits and applications. Segregation between free and non-free packages. All free packages built entirely from source. Multiple runtimes/development kits may be installed. Fedora includes: JPackage-compatible runtime and development kit packages. A whole bunch of applications. JPackage JOnAS Fedora©s Java Compilers gcj can operate in several modes: Java source (.java) to Java bytecode (.class) Java source (.java) to native machine code (.o) Java bytecode (.class, .jar) to native machine code (.o) In Fedora: ECJ compiles Java source to bytecode. gcj compiles that bytecode to native machine code. -

We consider how an essential part of computing in-the-large. It elevates tools and techniques from the most software products – the user interface – can be successfully level of a craft, to where they can be efficiently and reproducibly engineered so that it can be portable across multiple platforms harnessed for the successful completion of large projects. and on multiple devices.

Concurrent Programming Made Simple: the (R)Evolution of Transactional Memory
Concurrent Programming Made Simple: The (r)evolution of Transactional Memory Nuno Diegues∗1 and Torvald Riegely2 1INESC-ID, Lisbon, Portugal 2Red Hat October 1, 2013 ∗[email protected] [email protected] 1 1 Harnessing Concurrency Today, it is commonplace for developers to deal with concurrency in their applications. This reality has been driven by two ongoing revolutions in terms of hardware deployments. On one hand, processors have evolved to a multi- core paradigm in which computational power increases by increasing number of cores rather than by enhancing single thread performance. On the other hand, cloud computing has democratized the access to affordable large- scale distributed platforms. In both cases programmers are faced with a similar problem: if they want to scale out their applications, then they need to tackle the issue of how to synchronize access to data in face of ever growing concurrency levels. For many decades, programmers have been taught to rely on locking mechanisms or centralized components to manage concurrent accesses to data. However, the ongoing architectural trends towards massively parallel/large- scale systems have unveiled the limitations of traditional synchronization schemes — not only can they significantly limit the feasible parallelism, when there may exist tremendous untapped parallel potential; they also force to use intricate programming models that are prone to tricky concurrency bugs, which can be a conundrum to detect and fix. In fact, popular knowledge considers locking approaches simple to understand, but difficult to master. 2 Programming with Transactions To tackle this fundamental problem in modern software development, during recent years both industry and academia have started to adopt Transactional Memory (TM). -
