I often work with tabular record data, either ascii or binary, in varying formats. Usually it's pretty simple to manage, but a bit tedious. I've been thinking of writing some code as a nice compromise between using XML for data interchange and interoperating with repetitive table formats. Once you have an XML descriptor for how the tabular data is laid out per record (row), you can write code generators to handle reading, writing, and manipulating that data. You could even have a XML header plus body data type setup to inline the data in a single file, and get to omit some of the XML verbosity. Does anyone know of any existing Open Source projects along these lines?

Since I've been playing around with RuWiki recently, I've had some tangential thoughts on how we represent, interconnect, and learn technical information. If its a topic that I have only general knowledge about, I generally do some google searches and start poking through the pile of links until I find what I need. What I been wishing for in terms of a learning environment is some way of searching and navigating for technical information at varying levels of detail. Let me give an example.

Go to WhizBang Educational search engine.
Search on topic: Ancient Egyptian Civilizations
Maybe the top level of detail (LOD) is at a grade-school level - an encyclopedia type article saying where they lived, pyramids, blah, blah...

I get interested in pyramids, but this grade school stuff is too general, so I change topics to Pyramids and ask for the next LOD. Maybe thats SciAm or National Geographic type articles about the Pyramids.

Cool. But now I'm really interested in Pyramids and would like even more detail. Down one more LOD and I'm reading Archeology Today and maybe a few academic papers. Reading one of the papers, I read about a dig that happened last year. Another LOD and I'm looking at the raw field report data, photos and sketches of the archeologists and students.

I can wish can't I...

RuWiki

I need to replace my prototype markup code with something more robust. I have a multi pass process laid out and just need to find time to code it up. I already have the beginnings of a "plugin" markup and backend storage structures. I'm thinking that different projects can specify different markup transformations as well as different backend storage schemes.

I'm getting close to a workable version of a Ruby Wiki - currently titled RuWiki. There a couple of others that exist already, mostly they're difficult or impossible to install on a site host when all you have access to is the standard web services.

RuWiki is designed for multiple backends - currently the only one is a flatfile. MySQL or PostgreSQL will probably be next. The twist for RuWiki is that you can define different "Projects" which essentially create separate namespaces for Wiki topics. I need to decide on a notation for cross-project notations still...

I decided to start looking for full-time work. I've been working small projects, but that was never the intent of Digikata. I'd like to see something in the Open Source area, but it's more likely that I'd return to my roots in Aerospace Engineering (or Engineering related simulation and modeling).

I'm going to try to keep up at least a once-a-month posting to Advo.

Well, it looks like Digikata will not be winning a Linux based proposal to develop school administration software. The fustrating thing is that the evaluation comments said that they were extremely comfortable with the competence of the team, but basically "not a mainstream OS"... And this after spending extensive sections of the proposal explaining why Linux would be so advantagous to the education sector.

Anyway, I think it's time to find a regular full-time job now...

Started to write a ruby+postgresql contact manager. Right now its mosly a little application to run through a list of potential clients and tag addresses with labels and tracking notes. I'll probably finish enough features to make it usable and then live with it for a while to see how I like it. So far ruby+glade+gtk seems pretty quick to develop with.

julian: College is only a (weak) approximate model of the real world. I feel for your fustration. If anything, I often sense that adademia eschews real world experience as "solved" issues - therefore the pragmatism of it all might taint you for academia. College is really a test of endurance, can you stay committed to one goal long enough to accomplish it? Oh, an by the way, you might as well learn some foundation information which may or may not be useful in your future endeavors.

When you re-enter the real world for a while, you'll find that it is much better suited for people who "get-it". It's not perfect, there are certainly patches of cluelessness aplenty, but people who know what they're doing get rewarded more often. And if you don't, move on to someplace that suits you. It's your choice.

Anyway, I should be getting back to my proposal now. Proofreading -- Ugh.

Received this inside a spam today:

$10,000.00 Investment could have returned $25,000.00-See How

200% return could have been achieved in less than 30 days!

If you're going to try to scam people, at least try to get your numbers straight. Sigh... forwarded to uce@ftc.gov

test entry from advogato.rb ruby utility

Haven't posted for a while. I've been busy - the entries stopped just before my son was born... babies are a lot of work!

Anyway, fun new (to me) Debian utilities are apt-proxy and apt-spy. Apt-proxy is working happily on my home-office mini-network now and I'm playing with apt-spy.

Was invited to submit a followup proposal for my education project, writing it up now.

Also trying out a advogato ruby post script -- fun.

Working of filling out more of the functionality of my prototype. Anyone who is involved with administering the U.S. Federal Headstart program for their local area may eventually be interested in the Open Child Development System (OpenCDS) product. (no public versions availiable yet, mail me if interested) With the support of my local school district and the Dept. of Education.

I'm prototyping a core database schema that an organization can use to track program information. (As well as stay fairly independent of specific program forms and data collection requirements). Oh yes, this is all web based letting them use their existing desktop computers and whatever OS they want for the clients. (Although, I'm recommending Linux as a cost saver in the long term) Their sys admin is very unhappy about the new/upcoming licensing requirements for certain proprietray vendors.. :)

The idea is also to make it cross program for various other city, county (LA. Co.), and state (CA) child related programs. It is estimated that 95% of all the information collected from a potential recipient is common to all the programs anyway.

I spent this weekend reading and writing for a new, related proposal (also open source, not education dept. related). For the moment this shall remain nameless.

I also continued repainting the spare bedroom, getting it ready to become a nursery. The color my wife and I chose was darker than the color sample as it dried, but it lightened up to match when completely dry. Tonight is layer 2...
