Issuu just
announced it has raised $5 million in a Series B investment from
Sunstone Capital, which had already provided Series A funding to the amount of $1.25 million in early 2007. The Copenhagen, Denmark-based startup has also added a slew of new features to its existing product and launched a premium version for professional publishers. When we first came across Issuu, which turns uploaded documents into interactive online publications for free, we said it was one of the first service of its kind that
didn't suck. In addition to the funding announcement, the company is also releasing a major product update.

We've made some progress on the USB gadget driver for Linux, and we're now running a generic serial gadget for communication. This implementation is important because USB is now a lot less laggy and things like ethernet over USB, etc., can eventually be supported, easing access.
We've also got pretty far with porting the NAND driver to Linux. Most of the read support is now there, and we've isolated the routines in the iPhone kernel where the raw hardware write occurs. CPICH and c1de0x are working on reversing it. Hopefully, it will be analogous enough to reads that it won't take a huge amount of time to work out.
This is different from reversing their FTL, however, which is a complicated slew of data structures, merge buffers and other exotic algorithms that take care of evenly distributing writes throughout the device and also making writes take less time.
I think reversing all of that would take too much time and effort. Instead, my proposal is to just reverse the hardware NAND writes. Instead of using a partition, we would have a loop-mounted root filesystem (similar to how Wubi is setup), with the root filesystem being a file on the Media partition. Since there's a non-empty file at that location, the FTL system, whatever it is, must create a one-to-one mapping from logical sectors to physical NAND pages. We can already read the mapping it creates (we have already reversed the read-side FTL code), and so all we have to do to alter the data is to write to the same pages we would've read from. Of course, this means that wear-leveling and bad block handling is not performed. However, if we use a filesystem that's aware of bad blocks and can wear-level (YAFFS or JFFS2), then it amounts to the same thing. The wear-leveling would then take place over the particular physical pages belonging to the rootfs image, rather than the entirety of the NAND. This would make the physical pages belonging to the rootfs image wear out a little faster than the rest of the NAND, but the actual effect of this should be inconsequential.
The additional benefit of this setup is that there's no repartitioning required, so setup is cinch. See
this wiki document for specific proposed implementation details.

Man, poor Toshiba. The company's already sucked up its pride and started
putting Blu-ray drives in
its laptops, but here's its first stab at a proper standalone player, the
BDX2000, on Best Buy shelves a bit early for $199 -- or $50 less than its announced price. Sure, that makes sense given the falling prices of Blu-ray decks as the holidays approach, but even at that price it's not super competitive with the slew of other decks out there that can do Netflix streaming. We'll see if Tosh's next efforts are a little
more interesting than this, or if this is just more heartbreak than its worth.
[Thanks, Alex]
