Threaded code - Wikipedia, the free encyclopedia: "Threaded code
From Wikipedia, the free encyclopedia
Jump to: navigation, search

For multi-threaded programming, see Thread (computer science).

In computer science, the term threaded code refers to an implementation technique for programming languages that produces very compact code. Threading is a form of code consisting entirely of subroutine calls, written without the subroutine call instruction, and processed by an interpreter, which jumps to each successive subroutine in turn.

Threaded code is used in the Forth and early versions of the B programming languages, as well as many implementations of FORTRAN, BASIC, COBOL and other languages for small minicomputers.

The benefits of extremely compact code, in some cases, come at the expense of slower execution speed. However, in other cases there is a synergistic effect -- sometimes threaded code is smaller and faster than non-threaded code. In systems with virtual memory (where memory is simulated with a mechanical disk drive), threaded code may be hundreds of times faster than a less-compact design that does not fit in the available physical memory, because disk drives tend to be roughly a thousand times slower than random-access memory (RAM)."

Two PhD theses on reliable, distributed systems:

From Lambda the Ultimate:
E Thesis: Robust Composition

Mark S. Miller's PhD thesis on Robust Composition: Towards a Unified Approach to Access Control and Concurrency Control is now online.

When separately written programs are composed so that they may cooperate, they may instead destructively interfere in unanticipated ways. These hazards limit the scale and functionality of the software systems we can successfully compose. This dissertation presents a framework for enabling those interactions between components needed for the cooperation we intend, while minimizing the hazards of destructive interference.

Great progress on the composition problem has been made within the object paradigm, chiefly in the context of sequential, single-machine programming among benign components. We show how to extend this success to support robust composition of concurrent and potentially malicious components distributed over potentially malicious machines. We present E, a distributed, persistent, secure programming language, and CapDesk, a virus-safe desktop built in E, as embodiments of the techniques we explain.

E rates as a (very) important language for anyone interested in ideas of messaging, distribution and security. The nice thing about a thesis (such as this one and Joe Armstrong's) is that it gives a nice historical account of the related work and influences.

.NET Decompiler: "It was only a matter of time before decompiling of .NET Exe's and DLLs to MS Interlingua became a reality. Here are a couple of industry strength .NET decompilers which produces some incredibly accurate results.

Salamander is a .NET decompiler that converts executable files (.EXE or .DLL) from Intermediate Language (IL) binary format to high-level source codes, such as C#, managed C++, Visual Basic.NET, etc. For more than 8,000 classes that have been tested, Salamander always produces equivalent and recompilable codes that are remarkably close to the original source codes.

Slashdot | Debugging Asynchronous Applications?:

Some great suggestions from this article!

"Debugging Asynchronous Applications?
Posted by Cliff on Wednesday February 08, @08:20PM
from the mind-your-breakpoints dept.
Communications Programming
duncan bayne asks: 'I'm attempting to debug a complicated telephony application, written in C#, that's almost entirely event driven. This is the first time I've debugged a large asynchronous application that isn't a GUI, and I'm curious to know what advice the Slashdot crowd has to share - have you any recommended tools, best practices, or common pitfalls to avoid?'"

I'm not sure if you are 2.0 yet, but if you are, start by taking a look at VS2005. In the debug department, enhancements include better JIT debugging, stepping into XML/Web services from a client, and state-driven object inspection. Object Test Bench (OTB) is a simple object-level test utility. You create instances of your objects, invoke methods, and evaluate results... to shorten the task of coding, debugging and re-coding. I'm not sure about telephony specifically, but WSE/WS* SOAP layers can be hard to manuever through in a debugger, yet VS2005 does it quite nicely via WSDL.

One other suggestion... "event bus" apps like you describe are good candidates for capturing as much runtime data as possible, so make sure you adjust your build parameters and do as much of that as possible, especially in problem assemblies. Oh, and don't forget to build nUnits. Sounds like you're walking into some prewritten code, but the effort might be worthwhile.

Author: Bart De Smet, MVP on Visual C#

C Sharp - Wikipedia, the free encyclopedia: "C# (see section on naming, pronunciation) is an object-oriented programming language developed by Microsoft as part of their .NET initiative. Microsoft based C# on C++ and was influenced by some aspects of Java. C# has a procedural, object oriented syntax that combines aspects of several other programming languages, most notably C++, Java and Delphi. Since C#'s principal designer was the designer of Borland's Turbo Pascal, Turbo Pascal for Windows, and Delphi, concepts from those languages are apparent in C#. Other contributions can be traced on a programming language history chart. C# attempts to fit well for both rapid development, like Visual Basic or Delphi, and for complete full-featured desktop applications."

Not automated but...

It can't really be automated at this point, but there are efforts being done for more language interoperability. .Net is one of the examples, and a lot of people are now reusing the JVM in order to be 'Java compatible'.

However for both of theses you need to target either an high level language (by generating Java or C# sources) or directly the VM bytecode (JVM or CLR). That's why I wrote NekoVM which defines an easy-to-target intermediate language and provide the VM and the libraries to run it.

It should greatly ease the language compiler implementation by providing a common runtime. And if you write a Neko -> Your language converter, you will be able to reverse the process, and translate other languages targeting Neko back into yours."

C? vs. Erlang? | Lambda the Ultimate: "C? vs. Erlang?

I know there was C? topic before. But the discussion really had more to do with Xen (XML, DB integration) than the Polyphonic C# concurrency part. I'm an Erlang newbie myself, but I already can see that asynchronous communication is the common thread to both languages and this approach is going to be big - can be used from embedded system to biz process orchestration.

Looking at the Santa Claus sample, C? code seems to be quite compact and the syntax extension to C# is minimal. However process/thread creation is implicit, and it seems to be a little more difficult to reason. I would imagine a solution in Erlang clearer, but maybe longer.

Any thoughts/pointers on the pros and cons of different concurrency approaches? We really should have a 'great concurrency shootout'."

MochiKit – A lightweight Javascript library: "MochiKit makes JavaScript suck less

MochiKit is a highly documented and well tested, suite of JavaScript libraries that will help you get shit done, fast. We took all the good ideas we could find from our Python, Objective-C, etc. experience and adapted it to the crazy world of JavaScript.
Reliable

MochiKit has HUNDREDS of tests. We build real applications with this thing. So even though development can move fast, we make sure to get tests written. This also makes platform compatibility issues much easier to detect and resolve than the 'guess and check' style of quality assurance seen in some of the other libraries out there. It's not broken.
Documented

You're unlikely to find any JavaScript code with better documentation than MochiKit. We make a point to maintain 100% documentation coverage for all of MochiKit at all times. You don't have to fumble around reading our source code or leafing through examples to find out how something works.
Evolutionary

MochiKit can adapt to anything you throw at it. It makes no assumptions about how your code needs to act, and it has hooks (by way of the the adapter registries) that makes sure that you can define your own comparisons, programmer representations, iterators, or DOM node coercion for any object in any way you wish. We'll gladly serve you all the Kool-Aid you want, but we're not goi"

Sriram Krishnan : Lisp is sin: "Lisp is sin

Confluence

Over the last few days, there has been one thought running in my head - 'All roads lead to Lisp'. I've tried to get it out of my head but like a tune from the radio, it has firmly lodged itself into my head and refuses to let go. Why this state? Call it a confluence of several items. In particular, these 3.

- Joel Spolsky goes off and writes one of his best articles ever called 'The Perils of Java Schools' which talks about the perils of not learning Lisp. As someone who has been playing catch-up with functional programming since I wasn't taught Lisp at college, I definitely agree. I forwarded that article to some senior folks internally - which in turn lead to some interesting conversations

- I've been working on a prototype of something at work - where I started off the usual imperative programming style. Realizing that this wasn't going to scale, I rewrote it in functional style making full use of C#'s anonymous delegates and iterators. When I had to make a major change, it was *so much* easier to add in extra functionality since I was just passing closures around.

- After 2 hectic work-filled weeks, I took advantage of a long weekend to curl up with a book which has been called the best book on programming ever - Peter Norvig's Paradigms of Artificial Intelligence Progra"

We describe the technical details of the approach and the results achieved, and discuss how to overcome barriers to adopting such best practice approaches.

Make your .Net application support scripting - a practical approach
Summary
Adding scripting support to your application is one of the most valuable things you can do for your client, letting them add value to your software, and keep it current over time with little or no overhead from the developers. Your users will be able to modify behavior at runtime, change business rules as the market changes and fix subtle bugs as they appear until better fixes come along in the form of compiled code. It is one of the most powerful techniques today employed my many varied business applications. But guess what? Its not very easy to do in .Net. In this article Ill show you how you can use some of the techniques of the past mixed with the .Net framework to add that scripting ability to managed applications, with a touch on a subject that was never considered for scripting: WebServices , including asynchronous calls to them.

Design by Contract Framework for .NET

• Download source files - 5Kb

This class library provides a Design by Contract framework for use in .NET projects. A Visual Basic .NET version is also included in the download but the following discussion is in C#. In both cases the library can be used by a .NET client written in any .NET language. (Though if the VB.NET version is used IntelliSense code comments will not be visible in the client application.)

"Design by Contract" is a method made famous by Bertrand Meyer in the Eiffel programming language where support is built right into the language constructs.

An Overview of the Singularity Project

Singularity is a research project in Microsoft Research that started with the question: what would a software platform look like if it was designed from scratch with the primary goal of dependability? Singularity is working to answer this question by building on advances in programming languages and tools to develop a new system architecture and operating system (named Singularity), with the aim of producing a more robust and dependable software platform. Singularity demonstrates the practicality of new technologies and architectural decisions, which should lead to the construction of more robust and dependable systems...
Singularity... starts from a premise of language safety and builds a system architecture that supports and enhances the language guarantees.

An interesting overview of what sounds like an intersting project.

The choice of implementation language is also interesting:

Singularity is written in Sing#, which is an extension to the Spec# language developed in Microsoft Research. Spec# itself is an extension to Microsoft’s C# language that provides constructs (pre- and post-conditions and object invariants) for specifying program behavior. Specifications can be statically verified by the Boogie verifier or checked by compiler-inserted run-time tests. Sing# extends this language with support for channels and low-level constructs necessary for system code....integrating a feature into a language allows more aspects of a program to be verified. Singularity’s constructs allow communication to be statically verified.

An interesting aspect is the support for meta-programming, which is implemented in an unusal manner:

Compile-time reflection (CTR) is a partial substitute for the CLR’s full reflection capability. CTR is similar to techniques such as macros, binary code rewriting, aspects, meta-programming, and multi-stage languages. The basic idea is that programs may contain place-holder elements (classes, methods, fields, etc.) that are subsequently expanded by a generator.

Many other intersting design decisions are discussed in the paper (e.g., various DbC facilities), so do check it out.

Working With Events Over Remoting by Russ Nemhauser: Subscribing to events of objects instantiated via remoting can be a tricky business. However, it is possible to build solid event publish/subscribe applications while using remoting simply by applying a few extra strategies then might not seem immediately obvious. Throughout the document, I will refer to the process that exposes the object for remoting as server and the process that instantiates an instance (local proxy) of a remote object as client. However, all of these processes may in deed take place on the same machine.

Friday, June 25, 2004 From Slashdot today: How Microsoft Develops Its Software Posted by michael on Friday June 25, @10:50AM from the remember-the-triangle dept. crem_d_genes writes "David Gristwood has a post on his blog that notes '21 Rules of Thumb - How Microsoft Develops Its Software', on which he will elaborate at TechEd in Amsterdam next week. It was derived from interviews with Jim Mccarthy, also of Microsoft. Gristwood: 'As someone who has been involved with software development for over two decades, the whole area of how you actually bring together a team and get them to successfully deliver a project on time, is one worthy of a lot of attention, if only because it is so hard to do. Even before I joined Microsoft, ten years ago, I was interested in this topic, having been involved myself in a couple of projects that, I shall politely say, were somewhat less than successful.' Tips include such features as 'Don't know what you don't know.'; 'Beware the guy in a room.'; 'Never trade a bad date for an equally bad date.'; and 'Enrapture the customers.'"

CS CODEDOM Parser -- a utility which parses the C# source code and creates the CODEDOM tree of the code (general classes that represent code, part of .NET Framework - namespace System.CodeDom). Also, many cool parser links. DEVLIB.org: Programming: Compilers: Lexer and Parser Generators -- including a free parser generator that works with .NET. GOLD Parser -- a free parser generator. Unlike common compiler-compilers, the GOLD Parser does not require you to embed your grammar directly into your source code. Instead, the Builder analyzes the grammar description and saves the parse tables to a separate file. This file can be subsequently loaded by the actual parser engine and used. Currently the GOLD Parser Engine is available in Java, .NET and ActiveX. [Open Source] JB2CSharp -- A port of the Java-Bison/Flex software developed by the Serl project at the University of Colorado, Boulder. Parsers and lexers will be able to use C# actions.

What about Windows users who want to use Linux in conjunction with their existing systems? KIVILCIM Hindistan explores the world of coLinux -- cooperative Linux. Netcat and Reverse Telnet by KIVILCIM Hindistan -- The venerable Unix utility cat has all sorts of uses, but it's limited to the local machine. Enter Netcat, a network-aware cat. KIVILCIM Hindistan introduces the Swiss Army Knife of networking. Homemade Embedded BSD Systems by Michael Lucas -- BSD runs nicely on older PCs, but they can be noisy and time-consuming to set up. Worse yet, the hardware may be at the end of its life. Is there a better alternative to dedicated (and closed) hardware devices? Michael Lucas demonstrates using BSD on a low-power, low-fuss Soekris box. Building a Parrot Compiler by Dan Sugalski -- Parrot, the virtual machine for Perl 6, is not just for Perl 6 anymore. It's a surprisingly high-level, high-performance target for all sorts of languages. Dan Sugalski demonstrates Parrot's capabilities by building a compiler for a simple, yet business-critical, 4GL. Dan is a coauthor of Perl 6 Essentials. Tuesday, May 11, 2004 .NET article: Performance Counters Determine Application Performance.

Compares 'n contrasts 'em all, complete with beaucoup references for each language. Tuesday, July 16, 2002 "There is a (not quite) new effort by the IETF to standardize a framework for network applications, called BEEP, the Blocks Extensible Exchange Protocol. Standardized in RFC3080, it takes care of all lower level tasks an application level protocol has to like framing, authentication and capabilities negotiation in a modular and lightweight way. In the current issue of Internet Packet Journal (a quite nice and free-as-in-beer technical publication by Cisco) is a well written Introduction to this framework. Why isn't anyone adopting this protocol besides some Java libraries like beep4j and PermaBEEP and a C library called RoadRunner. I couldn't find any applications based on this protocol, regardless of it's promised capabilities. Is everybody still inventing his own application layer protocol?" http://ask.slashdot.org/article.pl?sid=02/07/15/212226&mode=thread&tid=99 Saturday, July 13, 2002 Scientific Battlegrounds in Diets There's an interesting article currently carried by the NYTimes (free reg. yada yada) that talks about the world of dieting, National Institutes of Health, Atkins as well as low-carb vs low-fat. The interesting thing, from a scientific perspective, is the sheer lack of study - and the reticence from the scientific community to question the party line. Software evolution article in Salon: http://www.salon.com/tech/feature/2002/04/08/lehman/print.html The guy claims that software evolves and that you have to take these dynamics into account as a software engineer or manager.

Wednesday, July 03, 2002 ERD Apps a Missing OSS Niche? Pennyless Developer asks: "So the time comes when one must design a brand spankin' new database schema. You want to use an Entity-Relationship diagramming tool with hopefully some automatic schema generation tools, but do not have much money to purchase anything like Rational Rose. Like a true geek well versed in OSS, you head off to scan sourceforge, freshmeat, and google. But alas, it appears no such applications exist in the OSS world, at least none beyond the planning stage. The question I pose is this: What useful, OSS/Free/Cheap ERD applications have you found and used? Or do developers do all their ERD work under an evaluation period of commercial software?" http://developers.slashdot.org/article.pl?sid=02/06/30/2323205&mode=thread&tid=156 ANTLR: A parser generator that targets many languages.
