I don't know what your simple program does, but it sounds like it could be a Sugar bug. You should file a ticket at dev.sugarlabs.org. If it is not related to Sugar, we'll try to pass the report along to the proper place. http://dev.sugarlabs.org/ticket/465 It does sound like NM. Look at

In the old builds I could initiate a shutdown and close the lid and the XO just finished the shutdown. In the new builds when I close the lid the shutdown halts because of suspend (I think, can be mistaken). Could it be a little bit more clever about when to suspend? Or is it what you are

We can do a little better than that, actually, by making it all one prompt. It can have a name field, already filled out with the best darn attempt at a name we can manage, a tag field (and perhaps even a list of popular tags as well, to apply to it with a click or a drag/drop), and buttons

can you do the hash as you copy it? it should be pretty close to free at that point (since the CPU is waiting for memory/flash access it can do the hash calculationwhen it would otherwise be stalled) According to my measurements the GeodeLX can fetch a new cache line (32 bytes) every

To what end? AFAIK the zlib decompression (both in OFW and in the OS) is not one of the primary problem areas. Changing fs read from CPU bound to IO bound would change a lot of things, for example the boot could utilize a little bit of more concurrency. Unfortunately we will only see its

The Datastore can then provide two accessor functions: get_by_value(key) and get_by_reference(key). get_by_value() returns the contents of the file as a bytestring in memory. get_by_reference() returns the path to the metadata file, or another path linked (soft or hard) to that file. This
