Re: sudo, not su.

So you have to do $ sudo su - and then set a password to ssh in as root. +1 This is the same thing as in OS X. I've been able to do everything I need to from the command-line in OS X using sudo without ever having to set the root password. If there's a way to make this fit in with the security model and the concerns on the trac entry, then I'm all for it. nick ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

Not really; if the question is whether or not there is a clock application that is standard on the laptop, implicit there is a decision as to _what kind_ of clock application. It's that question that I wanted to highlight. So, what do you think about the idea of letting kids make their own clocks? I should have made it more explicit in my e-mail that I would certainly be in favor of a variety of different clock applications that reflect local conditions or are based on the logic or whimsy of the user. The only thing I would caution is that the clock construction environment should not privilege one type of representation versus another. Not that I am suggesting that you or anyone else is necessarily doing that; again, I raise the point for the purposes of making the question salient. nick ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

Bert Freudenberg writes: I question the very assumption that continuously telling the time is even remotely important on a learning machine for kids in elementary school age. Dealing with time is a critical life skill that must be learned. Having a clock is thus very important. Whose time? Hours minutes seconds? Days since a recent feast? When the sun is at a certain position in the sky? Since I last saw you on the road? How much do I quantize? Is quantization of time even a concept I am familiar with? The notion of time is _highly_ contingent on situated cultural factors. Just because in the West we measure things using hours, minutes, and seconds, does not mean that the entire world does so. In fact, our conception of time is directly related to churches and clock towers in the middle ages (see Lewis Mumford on this idea) first, and then assembly lines and educational/disciplinary institutions (see Foucault) . The rest of the world has not necessarily adopted our way of dividing days into ever smaller chunks---perhaps there is no quantization at all! A clock application, especially given the areas of deployment, is _not_ something you rush into with the assumption that you can merely write a graphic display of 00:00:00. One must understand the local conditions to know how time is told _on the ground_ and be careful to not impose a Western notion of quantization and temporal division that might be entirely foreign. nick knouf ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
