And what when you want to resume working on the subject... but can't remember exactly where did you stop, or even what was that great insight that you was so enthusiast about just a few days ago? Well, then you know what this blog is about - good ideas that need to be written somewhere; projects that deserve to be shared, if only to be saved from forgetfulness.Carlos Ribeirohttp://www.blogger.com/profile/16043745572254494898noreply@blogger.comBlogger91100tag:blogger.com,1999:blog-5784626.post-1100172259267523682004-11-11T08:15:00.000-03:002004-11-11T08:24:19.266-03:00

Weird idea. I just had to post it somewhere. Think about it: carbon nanospheres are strong, and light. Can they be vacuum-filled? (I'm wondering if I even can write it like this, but it seems that "vacuum-emptied" reads worse). A sealed vacuum sphere is lighter than a helium filled sphere of the same size. The problem is, of course, the internal vacuum pressure. I don't ahy any idea on what does

Academic Research and CS Innovation by Phil Windley: We've created an entire ecosystem based not on what is useful and good, but on whether or not we can convince a handful of other people that what we've written is sufficiently sophisticated to publish in their journals. It's a sound point, and it's something about which I've pondering for a long while. In my student times I liked to read CS

There is a whole bunch of things that can be discussed on the nature of social interaction on the Net. Social dynamics are very interesting. Most popular sites experience an early period of intense activity. As the community grows, first there is a growth on social involvement of its users, that can be measured by the average number of comments and messages left per user; but later, the sheer

We all know what blogs and Wikis are, but what the heck is PKM? Theacronym means "Personal Knowledge Management", and it describes a newcategory of software, bigger and more dynamic and interesting than oldfashioned PIMs. I have my own PKM dream, and that's why snippets areimportant.For those rare souls who don't know what I'm talking about, somedefinitions. Despite being relatively new in the

Well, nothing like a newbie with lots of enthusiasm! So that's myfirst post by email. That's something that will make keeping my blogup-to-date easier...

Well, I'm back to the House of Unfinished Projects. It's been a long time since my last post - almost one year! But since then I've been out of the Net, working at some entirely unrelated business; I had no Internet connectivity at my office, and I had to resort to LAN houses for my web surfing. I had no time for blogging at this time. Now, I'm back online. I'm still looking for the perfect

I think that there is a highly interesting link between the research on natural language processing and the war on spam. I'm not sure if both sides are aware of the extent of this relationship; this is both good and bad. Bad, because the two fields use different methodologies, and with a small number of exceptions, don't talk too much and don't share information as they could. But it is also good

I've read at Slashdot that two teenagers have commited murder after playing Grand Theft Auto. This obviously led to the discussion, "aren't our children being exposed to too much violence in videogames - movies - etc."? My opinion in this matter is that yes - in a way. The real problem is that our children (and I can say 'our', as I'm a parent of a 2 years old boy) are being raised too far from

Well. That's not my first blog attempt; in fact, I have started another blog, where I've posted only a couple of entries. So that's just another try - I hope it will be a better one (or at least a little bit more succesful).
