Great poetry.
Unfortunately the times have changed and we are ravaging the oceans with great success.

Unrelated, but I can’t seem to find the archive of your old posts before migration to this domain.

There were some interesting problems and posts I like to look at occasionally.

Oops. Have not been checking the comments lately. Actually, I made a huge typo in the original post. The norm being considered is the trace dual of the \(\infty \rightarrow 1\) operator norm, so it can be approximated to within a constant factor using the max-norm. As you say you can then solve for the max-norm with an SDP. The main issue is if you want a factor model, you care about the decomposition itself and not just the value of the norms, and there's no way I'm aware of to take the decomposition you get from the max-norm SDP and turn it into a sign decomposition of the matrix.

“This is an interesting norm both intrinsically (as a potential source of factor models in statistics and machine learning)”

Is it much more useful than the max-norm? Aren’t they nearly comparable, and the max-norm has the benefit of SDP computation?

Thank you, bbman335. I haven’t been experimenting too much since my last post, but I will try out what you’ve suggested (Dropbox – FolderSyncing). Good to know that the Moon+ sync option is for multiple mobile devices. Will be useful when I get a few more devices

Sorry, one more comment. It appears to be important to use the same filename between devices. Kind of a no-brainer but I screwed it up because of some changes in how I put files on the devices between the two. Now it works great!

Oh, I see someone already mentioned using Dropbox for sync. So far I can’t get it to work.

I recently started using Moon+ Reader because I wanted text-to-speech, which even Kindle for Android does not have. Previously, I’d used primarily Kindle for Android and Aldiko.

What’s really cool about Moon+ is that you can actually link it directly to calibre’s book server. You can run the server on your computer and then view it as a catalog from Moon+.

The other feature I really want in a non-kindle reader is the ability to sync reading between devices (like my Galaxy Nexus and Nexus 7), since I usually have my phone with me, but not always my tablet. Moon+ appears to be able to do this on a per-book basis with Dropbox integration. I’ve just now started to try it so I can’t vouch for how well it does(n’t) work. You have to enable it in the ‘Miscellaneous’ options when in reading mode.

One more comment: Calibre also has the option of syncing directly with MTP devices (such as Google Nexus 7) via USB. In that case, you bypass DropBox entirely.

But I do like the idea of keeping my eBooks in DropBox and just accessing the ones that I need.

Just to elaborate, with Calibre, you can just set it up to work directly off the DropBox folder. Click on the “Library” icon (it might say something like “XXX books”), then choose the option “Switch/create library…”. If the library is not already at the DropBox location, it will move it.

Of course, this assumes that you have enough space on DropBox. My eBook library is about 3 GB…

I also like the FolderSync option, although I might prefer to just sync those files that I am reading, keeping the space open for videos.
