The story is great, but the tile (and supposedly the moral of the story) is wrong. We should not do good deeds for some expected (or hoped-for) compensation or reward - on this world, or the other world. We should just do it.
"Hoy por tí, mañana por mí" is about empathy, not about literally expecting future reciprocation. In more practical terms, it's a polite way to refuse being rewarded for something done out of kindness.
Why don't you bookmark and cache ALL visited pages. And keep caches for, say, 30 days if space is a problem. I'm very likely to want to search/revisit something I visited 2 weeks ago. This would provide a set-it-and-forget-it approach to bookmarking.
The easiest way to informally prove that the demonstration is false is to imagine starting with a circle in a triangle instead of a circle in a square. Or with any other weird shape around the circle and follow the same "cutting" algorithm to infinity. This way you can prove that pi is equal to anything greater than pi.
This is clearly demoware, good enough to impress the general public. But once you go from "Draw a red circle" to "Draw a red circle overlapped one third with a blue square with white dots over the lower left corner" that would be progress. And then I wonder if this will also work: "Paint a white-dotted blue square that intersects over a third of a red circle in the lower-left corner. Or will it give a "compile error"
Why not just create a DSL (e.g. in Scala) with a simple standardized NL-like syntax that can give meaningful "compile errors". There is no need to impress the general public.
This is very unlikely to happen because:
1. When a startup sells shares (i.e., you purchase stock) it sells them not only for money, but also for advice and connections. Most of the time these are more valuable than the cash. Since you are likely (only) an engineer/geek, your part of the deal is short.
2. Even if they would want your money, evaluating a startup's worth (for pricing your shares)is extremely difficult and/or expensive. So the won't go through this process for a few thousand dollars.
Technically you are right, everything has a price. Except when that price is way too high. So if you think a share is worth between say, $5 and $10, they can either say (nicely) "we're not selling shares right now", or say (rightly and rudely) "we can only sell YOU shares for $1000/share". And that may really be a fair price from their point of view, since having you (a nobody in the VC world) as an investor is really detrimental to their image.
If you're hiring or looking for a co-founder, list your startup on http://www.startuplinkup.com. It's a simple, semantic wiki - a more permanent home for your search. Or you can find a startup to work for. (shameless promotion of my site)
Yes, I took the data, and refined it just a bit. I had to do it for about 170 of entries.
A semantic wiki is better than a plain Google Doc, by having the ability to run complex queries, such as: Search for a startup located in "Florida", in the "mobile" space, who needs someone with "ruby" skills. This is all "out of the box" thanks to the Semantic Mediawiki extension
Of course this is less fancy than your regular recruiting/social networking site, but the simplicity of it must be a plus. (you don't need an account to add/edit). The success of the Google Doc idea is also due to it's simplicity.
You can't delete pages, and people can still mess with your page: it should be locked to targeted underlying user. Also, there's no spreadsheet view, which makes it almost unusable to me: do you expect users to open 100+ tabs?
The wiki is about startups, but you sourced it from data about people. I am not a startup, I am a person.
Yes, you can delete and move/rename pages, but you need to create an account for that. This is supposed to prevent vandalism. Not sure why would you need a spreadsheet view. You can always use plain search. And than there is semantic search, which I plan to add soon. Having all that data in a structured database (every field/property in a page is query-able in a semantic mediawiki app).
About people vs. startups, you are right, they are no the same. I'm not sure what to call that entity that is something between an idea and a startup. If you create an account you can list your skills in the "Person form". There will be a search for that.
I just created this account (and one on startuplinkup) b/c while I didn't mind having my email on the Google Doc, I don't want it sitting on the wiki. According to the User group rights only Admins can delete. Care to help (Startup 155)?
Out of pure curiosity, as I'm sure all the startup folks are .. would you mind shedding some light into why you would be ok with your email on Google Docs but not a wiki?
Well, I know for a fact that my email on a traditional web site is going to be indexed and cached by search engines, internet archive, etc, while on the Google Doc, I'm a little fuzzier on how permenant and searchable my email address becomes.
In a nutshell, I wanted to avoid spam; from bots, not from users here.
If I had had this account the other day, I probably would have just added that.
I copied (almost) all entries from the doc in a semantic wiki: http://www.startuplinkup.com Please go and search your entry there, refine it, rename it, etc. Hope this is more manageable than the google doc. Follow @startuplinkup.
