The 12-in. PowerBook Thin and (Feature) Rich ReviewJust 4.6 pounds light enough to carry most anywhere, yet hefty enough to convey a feeling of solid construction. I believe it was Walt Mossberg at The Wall Street Journal who best summed up the 12-in. PowerBook. It s like one of those all-metal Leica cameras that just reeks of quality. I have to admit having taken a roller-coaster ride of sorts in the past couple of years since Ap p l e i n t roduced its aluminum PowerBooks. I fell fir s t for the 17-in. model (such widescreen real estate), then swooned for the first-generation 12-in. model (a hot little number in more ways than one, espe-cially when you sat it in your lap), then decided that for most users the midrange 15-in. model is the perfect blend of portability and power.
Along the way, I ve bought, borrowed or used just about eve ry combo of PowerBook features that Apple has built, and while I seem to have fin a l l y settled on the 17-in. model for my own use (I have one of the newer 1.67-GHz G4 PowerBooks at home), the entry - s i ze model is no slouch. T he old adage that you can never be too thin or too rich seems like a tailor-made description of what road warriors want in their laptops: thin, lightweight machines that are feature-rich and, of course, inexpensive.

Unfortunately, this database access code exhibits insecurities of its own. For example, you should never use the sa account (or an equivalent) to access databases from Web applications. Instead, use weak accounts that lack permission to drop tables, insert, update, and delete records, and the like. In addition, you should use stored procedures or parameterized commands in lieu of dynamic SQL commands for added protection against malicious input parameters. Finally, consider encrypting database connection strings to minimize the risk of information disclosure if your source code falls into the wrong hands. And note that truly paranoid ASP.NET programmers encrypt connection strings and store them in ACLed registry keys. When it comes to Web security, a little paranoia can be a good thing.
Don't bother looking for syntax errors: functionally, this page is just fine. Type your name into the input field and click the "Click Me" button, and a personalized greeting appears on the page. But security-wise, this page is a disaster-despite the fact that it's similar to countless sample pages found in books, magazine articles, and even the .NET Framework SDK.
Give yourself a pat on the back if you spotted the following flaws:
• The page neither constrains nor validates user input
• It echoes raw, unfiltered user input to the page

Silverlight is a new Web presentation technology that is created to run on a variety of platforms. It enables the creation of rich, visually stunning and interactive experiences that can run everywhere: within browsers and on multiple devices and desktop operating systems (such as the Apple Macintosh). In consistency with WPF (Windows Presentation Foundation), the presentation technology in Microsoft .NET Framework 3.0 (the Windows programming infrastructure), XAML (eXtensible Application Markup Language) is the foundation of the Silverlight presentation capability.
The Evolution of Web Development: Moving to Web.Next
When Tim Berners-Lee at CERN invented the modern Web, it was intended as a system that allowed static documents to be stored and linked on a network- based system. Over the years, innovation grew, with the logical next step being "active" documents that are generated at the time they are requested with time-specific or user- specific information. Technologies such as CGI empowered this. Over time, the ability to generate documents on the Web became paramount, and the technology evolved through CGI, Java, ASP, and then ASP.NET.
ASP.NET provided a milestone in the ability for a developer to develop quality Web applications quickly using a server-development paradigm and best- of-breed tools from the Visual Studio line of products.

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 anAccess Your openSUSE Desktop from Anywhere Using FreeNX PDFHow to install and use FreeNX in openSUSE 10.2 FreeNX is the free version of NoMachine’s NX Server, which makes fast, secure, remote X11 connections to enable users to access remote Linux and Unix desktop sessions over a data link such as LAN or Internet. The server has been developed in such way that it’s fast enough even over a low bandwidth and high latency connection such as a dial-up link.
This is one of the main reasons I will choose FreeNX over a common VNC program. FreeNX can be also set up as a proxy, so it will tunnel Remote Desktop Protocols and remote Virtual Network Computing sessions, giving them some of the same speed improvements. FreeNX uses high optimized techniques to compress the X11 data, minimizing the amount of data that needs to be transferred, providing a responsive and real-time remote desktop experience.

Get PDFMaya 104: DynamicsDuring this tutorial we’ll explore a number of features of Maya’s dynamics toolset.
In part I - the ‘membrane pore tutorial’ - we’ll create a scene with a turbulent membrane that also has a ‘pore’ dynamically floating in it. Next we’ll create a swarm of molecules that collide with the membrane (and can otherwise only traverse it via the pore opening). We’ll gain finer control over the behavior of individual molecules in the swarm through the use of expressions. Finally, we’ll add goals to the entire swarm and control the degree to which these goals affect the swarm’s movement.
In part II – the ‘blastocyst tutorial’ - we’ll look at how a piece of geometry can serve as a goal for particles. Specifically, we’ll create a blastocyst-stage embryo made up of blobby particles attracted to a sphere. We’ll control the behavior of these particles relative to the surface of the sphere. For the finale, we’ll squeeze the blastocyst out of the zona pellucida surrounding it by using a lattice deformer applied to the sphere.
Download pdf Maya 104: DynamicsProgramming in CSharp pdfCSharp is designed for the .NET framework. The .NET framework is object oriented. CSharp has a great set of tools for the object oriented programmer. CSharp is the first component oriented language in the C/C++ family. Component concepts are first class:
Properties, methods, events Design-time and run-time attributes integrated documentation using XML CSharp can be embedded in web pages. In C++ and Java primitive date types (int, double, etc) are magic and do not interoperate with objects. In Smalltalk and Lisp primitive types are objects, but at great performence cost. CSharp unifies this with no performance cost. CSharp also adds new primitive data types, for example decimal. Collections work for all types.
In CSharp, private is the default accessibility. The accessibility options are:
public - accessible to all
private - accessible to containing class
protected - accessible to containing or derived classes
internal - accessible to code in same assembly
protected internal - means protected or internal
Classes can be marked as public or internal. By default classes are private.

Vista and Microsoft Visual Studio 2005. Note that Windows 98 or Me are not able to run Visual Studio 2005. You should be familiar with the Windows operating system and PCs in general, and be willing and able to figure out the Visual Studio 2005 environment.
The emphasis in class will be on general programming concepts, not on the workings of Visual Studio (often referred to as just VS), and the code you write will be virtually identical to code written by students using a Macintosh.
Note that currently the cluster and Lair (the Tressider computer cluster) computers do not have VS 2005 installed. They have VS 2003, but it does not have our libraries. We are hoping that we will have this fixed soon. We will make an announcement on the course website when we have a version of VS on the Stanford computers with our libraries
Getting Started
In order to use your PC to write the programs for the class, you will need to install both a compiler and the special 106 libraries for your system.
Step #1: Getting and installing the Microsoft Visual Studio 2005 compiler
For CS106X, we are using Microsoft’s Visual Studio 2005 compiler. To install VS, you will download disk images of the installer CDs, burn them to physical CDs, and then use those to install the program. The easy way to do this is to go to http://msdn-ee.stanford.edu/VisStud2005.html and click on
