Killer .NET 4 feature: Memory Mapped files

“So what is it? A memory mapped file allows you to reserve a region of address space and commit physical storage to a region (hmmm, sounds like virtual memory, isn’t it?) but the main difference is that the physical storage comes from a file that is already on the disk instead of the memory manager. I will say that it has two main purposes:

  • It is ideal to access a data file on disk without performing file I/O operations and from buffering the file’s content. This works great when you deal with large data files.
  • You can use memory mapped files to allow multiple processes running on the same machine to share data with each other.“

OMG! You can even specifiy views on a memory mapped file… from different processes… .NET 4 FTW!

Hail Eris! All Hail Discordia!

I was in desperate need for an DDate equivalent running on Windows. DDate is an unix implementaion of date accoridng to the erisian calendar described in the principia discordia.

I only found some C Implementations. And since it’s fun to do I ported the original Discordian Date C code to C#.

You can download the C# sourcecode, licensed under CC-BY-NC here.

I also created a web page which displays the current discordian date and offers you to convert any gregorian date into discordian date representation.

This page can be accesses here. You can call another page with parameters and you only will get the ddate output back:

for example: http://ddate.schrankmonster.de/DiscordianDate.aspx?year=2009&month=6&day=9

Google Copy-Wave

Oh dear. Another hyped protocol/platform from Google… oh wait. It’s not from Google. It’ all started in Xerox PARC…

There are several papers that describe what Google now claims to have developed…

Conclusion: Go and read old Papers. As it turns out almost all newly hyped things have been described in papers from years ago.

Society for Geek Advancement

“”Being a geek means being so interested in something that you don’t care whether or not it’s cool.”

THE SOCIETY FOR GEEK ADVANCEMENT was founded upon the principles that we should all embrace our inner and outer geek and have fun while doing it. As individuals who love learning, innovating and believe in possibility as well as change, the second step of responsibility is to “be the geek that keeps on giving”. As a member of SGA, we work together as a global community to provide the tools and help others realize their true potential too!”
