Which database is more secure? Oracle vs. MicrosoftThis paper will examine the differences between the security posture of Microsoft’s SQL Server and Oracle’s RDBMS based upon flaws reported by external security researchers and since fixed by the vendor in question. Only flaws affecting the database server software itself have been considered in compiling this data so issues that affect, for example, Oracle Application Server have not been included. The sources of information used whilst compiling the data that forms the basis of this document include:
The Microsoft Security Bulletins web page
The Oracle Security Alerts web page
The CVE website at Mitre.
The SecurityFocus.com website
A general comparison is made covering Oracle 8, 9 and 10 against SQL Server 7, 2000 and 2005. The vendors’ flagship database servers are then compared.
he two graphs above show the number of security flaws in the Oracle and Microsoft database servers that have been discovered and fixed since December 2000 until November 2006. Each block represents a single issue with the sole exception of the single block in Q2 2005 of the Microsoft graph. This represents Service Pack 4 and whilst there are no related security bulletins or bugs listed on bugtraq the author felt it worthy of inclusion.

Frankly, it was a pain until DesignCad came out with paperspace templates.
To the new user, the existing templates are quite and more than suitable and may indeed be suitable for some experienced users and customers alike, but from time to time or as is required, an up to date template is required to:
1. look professional,
2. convey the information required by a given standard i.e. local council or Patents Office.
3. Your drawing standards and template requirements have changed.
My own business has a drawing template log, where any changes to templates are noted and dated. Why? For quality reasons and if my company is audited, I can show the auditor the trail of changes, if asked.
To the new user, creating templates can be a daunting task, even to a reasonably experienced user, so with this tutorial, I will endeavour to guide you through the task. Paperspace templates are all based on a standard, being ISO, DIN, JIS, ANSI to name but some. Most, if not all are based on the ISO Standard.

There are many topics to cover, so unfortunately we will not be able to go into much depth in the time available. However, feel free to contact any of the organisers after the tutorial if you have any questions. We are all postgraduate students who completed our undergraduate degrees in computing science at Glasgow, and we are happy to chat about your projects or anything else to do with software development.
Topics covered
This is a basic introduction to coding C# for mobile devices. However, at the end of the tutorial you should be able to:-
• Create a basic GUI application for Windows desktop machines
• Create a basic GUI application for Windows Mobile devices
• Create your own Dynamic Link Libraries (DLLs)
• Link to and use DLLs in your code
• Call native Windows API code from inside C# applications
It is vital that throughout the tutorial you try to understand the code you are entering and what it does. Please ask about anything that might not be clear in the tutorial text or anything you want more information about.
Creating a solution
Before we begin coding, we must create a solution in Visual Studio 2005. A solution can be thought of as a meta-project. It can store many sub-projects within it, and is simply a useful way of organising your development tasks. Open Visual Studio 2005 (Start->Programs->Compilers) and select File->New->Project from the menu. A window will appear showing different project types.Toshiba Satellite M30/M35 Series Users Manual pdfGetting Started Selecting a place to work Creating a computer-friendly environment Keeping yourself comfortable Other precautions Setting up your computer Adding memory Installing a memory module Removing a memory module Turning on the computer Opening the display panel Turning on the power Using the TouchPad™ Scrolling with the TouchPad™ Control buttons Disabling or enabling the TouchPad Setting up your software Registering your computer with Toshiba Setting up other devices Turning off the computer Closing the display panel Using external display devices Connecting the display device Directing the display output when you turn on the computer Adjusting the quality of the external display Using an external keyboard Using a mouse Connecting a local printer Connecting an optional external diskette drive Connecting external speakers or headphones Connecting a microphone

Stay constant regardless of mode. Module Specific Menus – Vary based on the Maya module in which you’re operating. For example, you’ll have various polygon manipulation menus when in Modeling, and texturing tools when in Rendering. Status Line Module selector – Let’s you change which Maya module you’re using.
We typically use Modeling, Animation, and Rendering. Scene Icons – basic New, Open, and Save icons. Selection Mode – Let’s you specify how you want to select parts of your scene. By object, or By Component type. Selection Masks – Assuming you’re selecting by component type, these buttons allow you to specify the component on which you’d like to focus Snap Modes – Can be helpful in creating uniform layouts. Essentially objects etc… that you create will move to discrete coordinates as defined by a grid. Render Buttons – Shows you what your scene looks like when fully rendered. Show / Hide Editor Buttons – Lets you control what is seen at the screen’s far right

I decided that the quickest way to get you up and running with your own web server would be to use Apache Friend's XAMPP. XAMPP is an application that combines Apache (the web server), MySQL (database), PHP (scripting language) and phpMyAdmin (database administration) all into one.
Normally, to set up a web server you'd have to install each of those individually. With XAMPP, you install one application and you have a fully functional server. Now, you're probably thinking, “Well, if it's that easy then why is this blog entry HUGE!?” Well. The reason this is a large entry is I am going to walk you through all the steps of setting up XAMPP AND make sure that you set it up so that it is secure!
The default XAMPP installation is meant for developers on a local network, not for a real world installation, however, there are ways of making the installation secure and ready for real world use. Also, there are a few other things we'll need to do other than installing XAMPP to get things going.
Installing on Fedora Core 5
There are many distributions of Linux out there, my distribution of choice is Fedora Core. I prefer it because I've always had the most luck with it and have friends who use it. The steps contained within this article could be easily applied to Ubuntu or another distribution.
You may also be asking me why I am going to install this using an outdated version of Fedora. The main reasonWorking with C# SerializationAt some point in the development of most software applications, design decisions are made about how to store and retrieve application data. For example, if your application reads and writes to disk files, you need to make basic choices about how to represent the data on disk. In this column we want to look a bit at C# I/O issues, and in particular at a mechanism called serialization. Serialization is used to convert C# objects into bytestreams, in a standardized way, so that those objects can be saved to disk or sent across a network.
The Need for Serialization
Let’s start by considering a couple of examples. The first one writes a floating-point value to a text file and then reads it back:
using System;
using System.IO;
public class SerialDemo1 {
public static void Main() {
// write double value to text file
double d1 = 0.1 + 0.1 + 0.1;
StreamWriter sw =
new StreamWriter("out", false);
sw.WriteLine(d1);
sw.Close();
// read double value back from text file
StreamReader sr = new
StreamReader("out");
string ln = sr.ReadLine();
double d2 = Double.Parse(ln);
sr.Close();
// compare values
if (d1 != d2) {
Console.WriteLine("d1 != d2");
Console.WriteLine("difference = " +
(d1 - d2));
}
}
}
When this program is run, the result is:
d1 != d2
difference = 5.55111512312578E-17
For some reason, our attempt to store a floating value in a text file fails. If we know much about floating-point, we may not be surprised, given that many decimal values have no exact representation in binary. For example, the common value 0.1 is the sum of an infinite series of binary fractions. Somehow our initial value got changed a bit, due to roundoff
