Prevent Windows Kernel From Using The Page File (PagingExecutive Function)

DescriptionPlacing the Windows (2000/XP) Kernel into RAM is quicker than allowing it to be paged.DirectionsIf you system has more than 256MB of RAM, then you should try this tweak. In theory, the kernel (and thus Windows) should run faster if it kept in RAM instead of the slower page memory.This involves editing the registry so make a registry backup before trying this. Navigate to: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\DisablePagingExecutive Setti... [More]

True Programming Language Independent IDE

I watch a video on http://channel9.msdn.com about how we will be able to mix C++, C# and VB.NET code files within the same project in Visual Studio 2005. Watch the video here: http://channel9.msdn.com/ShowPost.aspx?PostID=19445 I have an idea to take this one step further. It would be cool if the IDE would be able to convert C#, VB.NET and C++.NET code to any of the others. This way a VB.NET developer could load a C# application, edit in VB.NET, then save it back to C#. Then a C++.NET developer... [More]

Fill DataSet with multiple Tables and update them with DataAdapter

One way to fill a DataSet with multiple tables is to send the database multiple requests. Another way to do this is to use multiple SELECT statements in a single request. There are a couple of problems with doing it this way: The DataTables don't have the same name as the tables in the database, you have to set them yourself You can't update/save the tables to the database; to do that you must use a seperate DataAdapter for each table. Dim myAdapter as SqlDataAdapter = new SqlDataAdapter( ... [More]

Create your very own Supercomputer with MPICH

Early supercomputers used parallel processing and distributed computing and to link processors together in a single machine. Using freely available tools, it is possible to do the same today using inexpensive PCs - a cluster. Glen Gardner liked the idea, so he built himself a massively parallel Mini-ITX cluster using 12 x 800Mhz nodes. The machine runs FreeBSD 4.8, and MPICH 1.2.5.2. After working with his machine and running some basic tests, Glen's cluster looks to be equivalent to at least 4... [More]

Windows XP Service Pack 2 Available

I installed SP2 Final yesterday. I had SP2 RC2 installed since it was released to the public. I hadn't encountered a single problem with RC2. The enhancements of the WiFi support is awesome.

I finally got my Function Guide ported over from the mySQL database it used on my old hosting provider to the SQL Server 2000 database on my new/current hosting provider.

MSN WebMessenger

There is now a web version of MSN Messenger. Pretty neet, I think. I like the idea of a web application working and acting just like a windows application. The current Web Messenger isn't as feature full as the Windows application, but I would imagine they are working on it, since it is still in Beta. Check it out at http://WebMessenger.MSN.com  System Requirements: A web browser: Microsoft Internet Explorer 5.0 or later, Netscape 7.0 or later, or Mozilla 1.6 or later, running in M... [More]
