I have to commend Marco for pursuing this initiative. I think the only hope for the long term survival of the innovations in Sugar is to port those innovations out into mass market Linux software. (Currently, nobody adopts XO innovations like shared browsers and word processors, or improved

Surely the solution for reading books is to ignore pdf That's pretty limiting. There are more legal downloadable books available in PDF than in any other format, about 600,000 on the Internet Archive alone. Scanned-in paper books are still the most popular sort. Producing text, rtf, or html

That doesn't change the fact that using the XO is like walking neck deep in treacle. ... The real problem there is it's hard to isolate the slowness, I think largely due to the fact that the problems aren't isolated. Is there any central repository for information about where the speed is

The 8.2.1 early thinking is here: http://lists.laptop.org/pipermail/devel/2008-November/021388.html If we want to ship any G1 or ChangeTheWorld machines without DRM and with pretty boot, we'll want to put a fix for #7896 into 8.2.1 (and 9.1). The fix goes into /boot/olpc.fth in the software

So, the transfer rate dropped from about 9.6mb/sec to about 5.3mb/sec. I was afraid of this. Flash is pretty fast, and there's almost no parallelism available in it (e.g. you can't queue up a bunch of reads to occur when the data rotates under the heads, or start a seek early). Thus it's

Walter asked: Are there any places where Sugar is in violation of its licenses? Sugar is licensed under the GPLv2, and its source code seems to be provided. (Because it's written in an interpreted language, it never ships binaries -- I think. There may be some small parts that are written in C

Some of us are new to one or another part of this issue, and need a bit more background. o Can you list the offending binaries and explain their faults? Sure. For example, ls is part of the Coreutils. In 8.2.0, it's licensed under GPLv3+ (try ls --version); in earlier releases, it's

What about using a NAND partition as swap? Has this ever been done? Given that partition support is a recent development it seems unlikely. Swapping to the soldered-in NAND chips is a very bad idea. It will tend to wear them out rapidly. Even if you use load-leveling software (e.g. swapping
