It's also highly flawed. The radioactivity of bananas comes from potassium. But the human body controls it's potassium content.. if there's too much, it gets flushed out. So eating bananas will not increase the amount of radioactive material in your body.
This is completely different for e.g. radioactive iodine, which adds to the body's inventory of radioactive material.
In all fairness, if you want to make a contribution that is worth co-authorship of a paper, you might need at least a good amateur telescope (maybe on the order of 10 inch aperture) and a CCD camera.
With such equipment, and clear skies, you can do photometric monitoring of stars (e.g. for outbursts, or planet transits). Asronomers always have the problem that big observatories focus on big telescopes, and it's difficult to do things that require small telescopes, but long-term monitoring.
One example would be monitoring of the transits of extrasolar planets, to detect timing anomalies (which could be caused by undetected additional planets). Or monitoring stars with planets detected by radial velocity variations, to discover eventual transits. Or monitoring of ongoing gravitational lens events... there are quite a few oportunities for amateurs.
Ubuntu has apparmor sandboxing of firefox as an option that's turned off by default, and even if you turn it on it's not sandboxed enough IMO (firefox can read and write almost anything in the user's home directory with the exclusion of just a few directories).
It's trivial to simply run Firefox under a different user id. I use about three applications that need to access the net (web, mail, chat), and each of them gets started (via a simple wrapper script) under a different, dedicated UID.
..and their verification process was extremely intrusive and I know many people who just decided to stop using second life entirely over it. It involves basicaly forking over Credit Card information, in some cases a Birth Certificate, and yuor home address..
Totally wrong. Thanks to the relaxed privacy standards in the US of A, there's tons of readily available personal information in online databases that you can use to pass the age verification.
They measure cumulative size distribution (how many groups of size >= N) and churn (how many people leave the group for another one in a given period).
They are able to come up with a simple mathematical model for the behaviour of players (essentially: recruit people with diverse attributes/skills) that reproduces the observed data extremely well. And they also show that the alternative 'kinship' model (recruit people with similar attributes/skills) fails to reproduce the observed data.
I would say that their model does quite a good job at modeling some rather nontrivial data.
It's a big hit among the people who have the creativity to actually do something, rather than just consuming. It's a big fail with those who expect a game with a set goal, those who need to cling to someone/something telling them what to do.
I'm doing freeform roleplay, and it's great fun. There's plenty of roleplay communities in SL.
3 - Cut and Paste really isn't an issue anymore, either.
I beg to differ - it wasn't an issue, but now it is one. Once upon a time, every app supported the standard way of cut and paste (right and middle mouse button).. but now we have apps who do it like this, and others who want me to do Ctrl-C / Ctrl-V because someone thought it would be cool to emulate MS Windows and force me to get my hand from the mouse and to the keyboard. And then there are apps where cut and paste would work one way for some input fields, and the other way for some other input fields...
