Hello everybody.

Things have been crazy the past six months or so. I have been extremly busy with work, and have not had any time to post. The fact is, I haven't had much time to do anything non work related.

Anyhow, I am in the process of planning a company wide Linux rollout (desktop and server!) I will post here as I make progress.


I just released xlhtml 0.5. I have really modularized the code, into several separate pieces. Now work begins in earnest to turn xlhtml into a library/application. I hope to have version 0.6 out by the end of the month.

xlhtml fixes
I fixed some bugs (memory leaks and the version display) in xlhtml, and put the fixes in CVS. I have been *VERY* busy as of late, and have not gotten as much time as I would like to work on various projects. Such is life :(

I am figuring out how to use IpTables. I am also learning more and more C.

Web Site Update

I just did a major update of the Chicago developer page. I will be overhauling the xlhtml page shortly.

Excel Encryption

Well I have been doing some research, and I have found that Adobe Acrobat encrypts its files almost exactly like M$ Excel/Word do.

Details of Adobes algorithm can be found here (PDF File) in section 5.18(page 62) and section 6.13 (page 124)

I will be contacting Adobe, and asking them if I can post the info on my website.

New Advogato Features

New HTML Parser: The long-awaited libxml2 based HTML parser code is live. It needs further work but already handles most markup better than the original parser.
