Ruby Programming - Delightful LanguagesThis is a brief recounting of my initial impressions of and experience with the Ruby programming language and its community. In many ways Ruby strikes the same chord in me that Perl did a decade or more ago. I show Ruby from a Perl perspective. When I first encountered Perl, I found the language to be a little strange coming from a C background. From time to time I would use Perl to write things I would have written in C or shell, and soon Perl was my tool of choice for many tasks. Ruby is having a similar effect on me. Sometimes I prototype Perl code in Ruby, sometimes I just use Ruby for the sake of seeing if I arrive at a different solution using a di?erent language.
Like Perl, Ruby makes programming fun, but in a different way. Ruby borrows features from many languages, and one of those is Perl. I can simply translate Perl code into Ruby if I want. I will use the Soundex function as an example, as the algorithm is simple and my Perl implementation will reveal something about my abilities as a programmer. The Soundex algorithm is a simple hashing of the letters of a word to a four character code which brings similar sounding words to the same code. In 1994 I posted a routine, shown in code listing 1, to comp.lang.perl which shows both the simplicity of the Soundex algorithm and my Perl style at its worst (or best).

There are also a great number of tools and libraries available on many platforms to facilitate working with FITS. We present the FitsLib 1, A library written to facilitate development of astronomical data analysis tools on the Microsoft.Net Platform. This has been developed as a wrapper over one of the very popular and time tested FITS libraries, CFITSIO. Fits.Net library merges the advantages of speed and ruggedness of CFITSIO with the language independence of the Microsoft.Net technology and a simple Document Object Model (DOM). We believe this library will be intuitive for .NET programmers. We present the design and usage patterns of the library in C-Sharp. We also discuss performance issues of the library. Finally we present a number of applications and web services, which are currently running on this library.
We wished to use the CFITSIO package in developing image cutout services on the Microsoft’s .Net Platform in the C-Sharp language. This is a comprehensive library and we did not feel translation was viable, C-Sharp does allow use of managed C++. We set out to wrap a minimal set of routines in the managed C++ programming environment.
This minimal set, however, grew larger as more functionality was required in C-Sharp. It became apparent that developing code with so many pointers and unmanaged data objects in C-Sharp would prove to be prohibitive, both for development and for maintenance. This led to the design of anDiagra 2.0 Fund Charts – step-by-step tutorialReportLab’s Diagra product lets you create data-aware charts and drawings. It can be used in many industries and many ways. The most comprehensive documentation is in the main manual, ‘diagradoc.pdf’. This is a supplementary tutorial intending to provide step-by-step instructions for a first-time user.
Many users are working in the fund management industry producing highly similar charts. This extra manual provides step-by-step tutorial to create several data-aware fund related charts. It is intended to be used with a sample database, delivered in a file ‘diagracharts.zip, which includes both data and runnable chart modules similar to the ones described herein. This manual is still being expanded, but should be sufficient to let a first-time user create a working data aware chart and carry out basic procedures. In the meantime feedback on what to add to this tutorial would be most welcome.

You set up the translation environment in transactions SLWA and SLWB. Implementation Considerations Before you start maintaining the translation environment, you should: · provide or extend system resources - please see System Resource Setup [Page 10] · perform administrative measures and preparation - please see Administrative Measures [Page 11] The translation environment must be defined before the start of productive translation. Integration After you have completed the above preparation, you start maintaining the translation environment in transaction SLWA.
Transaction SLWA is used to maintain the control tables for translation and to set up the translation environment. Authorization for some of the functions used in SLWA depend on: · the profile S_ADMI_FCD with value TRNR, which is only assigned to administrators - this is assigned in the user master record · the authorizations assigned to users in the translator profile in transaction SLWA itself.

The paper summarises the challenges institutions face in preserving Web resources, describes the workshops organized by the project in order to identify the challenges and identify appropriate best practices, and outlines areas in which further work is required.
The preservation of Web resources is a topic that is of interest to many involved in digital curation issues. It presents many interesting technical challenges in terms of capture and access, and organisational and resourceoriented problems, some of which are shared with other aspects of digital preservation and some of which are unique to Web resources. How does one select material? When are we trying to preserve information and when is it the experience, behaviour or appearance that is paramount? How straightforward is it to move Web resources between curatorial environments? Most everyone knows that information persistence on the Web is a fragile thing. And, as Rusbridge has observed [1] even those who care about information persistence don’t necessarily do a good job of it on their Web sites. This, despite the fact that good advice about URI persistence has been available for some time [2]. URI persistence is just one small (albeit important) part of the problem that illustrates the wider issues that surround Web preservation in an institutional context.

This does not reverse the coolant flow through the engine, it simply allows the pulley to be driven with the HTD belt instead of using the back-side of a serpentine belt. No modifications to the water pump impeller or water pump pulley are allowed. This photo shows a typical “burp tank” installation.
The tank is mounted as high on the dash as possible. One line runs from the center of the tank to the radiator, and another line runs from the bottom of the tank to the water elbow at the rear of the cylinder head.

Its staunchest advocates proclaim it a complete philosophical and technological reworking of how the web functions. Others declare that it is meaningless. However, most agree on common characteristics of a Web 2.0 application, such as increased interactivity, the acceptance of user input for building community and a reliance on client-side functionality. Additionally, Web 2.0 applications can be more vulnerable to exploitation by hackers than their predecessors. Hackers spend most of their time gathering information. When Web 2.0 applications push functionality and code to users, they provide hackers with information that can be used for formulating attacks. Often, old attacks such as cross-site scripting become more dangerous when used against Web 2.0 applications. This white paper defines some of the common technological components of Web 2.0 applications and discusses ways of securing them against exploitation.
Web 2.0 components
Web 2.0 uses the web for delivering information that is often created through community contribution. Wikis and blogs are good examples of these types of appli cations. The main attribute of a Web 2.0 application is interactivity. More functionality is on the client, and less is on the server. As a result, requests are updated in the browser without refreshing the entire page. For example, consider Google Maps. Instead of a static page, you can drill down or zoom in and out of a map without making requests for a new page. You can use several key technologies—or more appropriately, groupings of differentD-Link DCM200 Manual pdfThe DCM-200 provides customers with high-speed access to the Internet through the cable TV (CATV) network.
