Prometheus News

[code_glitch]

A tad more news in the unwind of code leading up to exam week - the PM_DataFiles unit is in its first implementation although at the moment it is quite limited - a maximum of 255 characters for the Name of a record and 4k (4096 bytes) for the actual value Although in its second revision this should be rectified.

The framework for detecting file types in undergoing final tests but will be quite limited out of the box - only mp3, wav, ogg, png, jpeg and tga detection although more could be added by modifying the constants line in PM_FileTypes, all courtesy of keeping the weight of prometheus down.

In other news, it has been found that the UPX utility can squeeze prometheus into a poultry <100k for a default compilation - no DLLs etc required so this is quite a bit lower than previous iterations.

Also, looking out for a jpeg/bmp loader as well as a PM_DataFS unit that can store multiple files inside a Prometheus Data Storage file (.PDFS) as a sort of filesystem - such as raw proemtheus images and since each record eats up 4k at the moment, I'm implementing a basic compression system for all that white space too

So lots of stuff going on, hopefully rolling out at the end of the weekend or in early next week.

Just a few teaser stats on the data file system: loading a 21mb data file of 5200 records takes you a cool 51ms on a 1.3ghz dual core machine with an ageing stock, mechanical HDD... Thats around 375mb/s for those that were counting
