Played with Process Algebra, made some breakthrough progress on my parser, playing with some MOM b2b tasty treats.

Oh, and I moved my desktop (again) to linux. Running redhate 7.0 with the nVidia binary drivers, (and locked up my machine good a few times overclocking my video card with nvclock). kernel 2.4.9 is on here. The documentation lies, my full gig of RAM is not seen without the BIGMEM patch.

fuckers.

more tomorrow (today) after sleep (coma).

You know what's weird? I installed Scheme on my desktop before I even installed a JDK and E. No, it means nothing.

Spent the weekend with my girl. Forgot my Go book with her today. :-( Just when I learning the intracacies of Kageme and Two Me.

Today I:

• enjoyed my george foreman grill. I made some soy patties.
• actually worked hard on my parser but didn't write more than a dozen lines of code.
• watched a cheesy movie which could have been really good
• thought about revamping my resume.
• oh, my 13w3->svga converter showed up. goddamned irix won't let me in. At least linux has a nice single-user mode. I guess I'll have to either acquire IRIX media somewhere or just say fuck it and pass the indy off to somebody else. I can definitely see it being a major time-suck for me.

Oh yes. the Indy's hardware specs:
150Mhz R5000, 8bit graphics, 64M RAM, 500M HD.

I recently aquired an indy r5000. I have no idea of it's specs, as I'm still waiting for my 13w3->svga converter so I can fire up the bastard. FYI, Libnet compiles on irix 6.2

Also, I've been working on my Java version of a parser for Casper. It's recognizing variable declarations now! I'll put the code online soon. I'm building a non- deterministic recursive decent parser using Steve Metsker's framework for building such beasts.

This is the greatest thing since sliced bread.

Spent yesterday and today fighting with setting up Alexandria, which is the software SourceForge wrote to run their site.

Also working on my rd parser for OpenCSP.

I'm glad to see that news coverage is as bad in other countries as it is in ours.

In other news, I started adding all sorts of #define's in libnet-headers.h so that I could easily have access to all the packet flags (SYN, RST, PSH, URG, ACK) when calling libnet_build_tcp() but then I realized that it's just easier to add the existing constants together. Let me explain for people like me:

(in libnet-headers.h):

#ifndef TH_FIN
#define TH_FIN    0x01
#endif
#ifndef TH_SYN
#define TH_SYN    0x02
#endif
#ifndef TH_RST
#define TH_RST    0x04
#endif
#ifndef TH_PUSH
#define TH_PUSH   0x08
#endif
#ifndef TH_ACK
#define TH_ACK    0x10
#endif
#ifndef TH_URG
#define TH_URG    0x20
#endif

What was immediately obvious to me is that when you add any two or three values together, you'll have a new distinct value. What's funny is that instead of just realizing I should add them together while calling lib_build_tcp(), I thought it'd be easier (and more useful to others) if I added a shitload of new constants. like TH_SYN_FIN_RST_PUSH_URG, etc.

What is wrong with my peer group? Get a little cooze in an IRC channel and everybody becomes a moron.

How did I magically become un-certified? I really don't understand advogato's certification implementation. And yes, I've read the spec. No, I'm not a moron.

I'm taking a few days off from my ERTP stuff to write a paper on E and to finish getting Java2 certified. Also swimming in Sacramento.

I shall return Monday with renewed vigor!

New Class Diagram created (an accurate one this time), I placed it on the ertp front-page. Also, did a lot of work on the code, cleaned up some ugliness, identified some more ugliness, and javadoc'd the whole shebang.

the Java/ELib MintMaker is nearing completion (and compiles currently): http://sieve.net/ertp

This is under the release early, release often strategy, expect it to change rapidly over the next few days.

I should probably just set up a cronjob to check this stuff out of CVS at a certain intervals.

update: oh yes, have a good hearty laugh at this.

Update (8:30pm): I've made some changes to the code and have also set up that directory so that it reads off of my CVS tree. cheers.

Update (1:25am): I've added a rudimentary class diagram here

Spent this evening hacking on the Java/ELib MintMaker. Nearly there.. I'll open it up as soon as it compiles. Remember, it doesn't actually _do_ anything much by itself.

ERTP would be a great place to start with OpenCSP.

nchriss stopped by tonight, we had a fireside chat about OpenCSP and gh0st.net stuff in general.

Listening to the US Bombs again after a brief pause.

Also, thanks to nchriss I finally remembered the super sekret to getting DOS 5 to boot on my old laptop again.. format never had an /mbr switch, only fdisk. duh
