第一次整蒜蓉開邊蝦。唔記得落酒,加上蒜蓉唔夠蓉(應該用grater、石磨或者garlic press)。雪櫃仲有幾兩蝦,下次再試過。

To enable installing apps in NookMarket:

Twook (version: 0.0.8): consistently turn the screen off when I move from the password field to the submit button. Solution: press any page flip button to turn the screen back on in the login page. Reading tweets on Nook is great but tweeting one isn’t, because of the lower sensitivity of the keyboard compared to iPod Touch and you need arrow key to navigate to your typos and correct them (no spell check of course).

WikiLocker: allows you to lock your wifi so it doesn’t turn off (beware of battery drain), turn wifi off, keep touchscreen on, disable screensaver and stop adb.

It would be nice if there can be gamma settings in the pdf viewer—the CMR fonts commonly used in LaTeX appears to be thin on screen (both computer and Nook). I have yet to figure out a way to hack this:

The first one is the original APDFViewer output whereas the second one is an image processed with gamma=0.5 from the computer. PaperCrop will do this for you but the resulting file is huge because the pages are converted into images in PDF.

Bookshelves do not survive a reboot? Why?

(This is not meant to be a detail review, just a few points that interest/annoy me.)

Chinese file name is supported, but for EPUB format books a CSS has to be added so that it will use the built-in font for displaying Chinese, or otherwise you’ll get ‘????’. For PDFs it relies on the built-in fonts for displaying Chinese.

The built-in Chinese font is okay, but if you think it’s not, you can slip in your own font.

Nook uses Adobe ADE (Adobe Digital Edition) to display PDFs and EPUBs. If you choose a font size that is too big for a page, it starts to reflow your document. The result may not be what you want: (i) words can be broken half way depending on the PDF, and (ii) formulas would be unreadable.
(There are 6 font sizes for you to choose from, but Nook only maintain a global setting which means you cannot have small for one file and medium for another—you must switch the font size every time. [Mine is on firmware ver 1.5])

The USB mode is good—no software needs to be installed on the PC side (although you may want to install Calibre—a free ebook management software)

Screensaver: choose between Cityscape, Nature (nice) and Authors (not that good). There are a couple of images in each set.

Charging light does not disturb reading—it’s at the bottom and you won’t see it from the front.

If you don’t crop the PDF it’s likely you’ll get sub-optimal results (a lot of white margins)

(cropped PDF)

After you have hacked (root) the Nook there’s another option for viewing PDFs (APDFViewer). When opening a PDF file it will ask you which one to use.

APDFViewer allows landscape mode. You need to crop the white margins of the PDF, though, because by default it does “fit to page" in portrait mode and “fit to width" in horizontal mode. Other zoom levels exists, but is limited to 25%, 50%, 75%, 100%, 125%, 150%, 200%, 250% and 300%. There’s no “panning" from the touch screen and buttons provided are minimal (from left to right: zoom level, rotate (upright or 90-degree clockwise; edit: long press for clockwise), page up/down (tap and hold for page selection slider) and quit. (as of ver 0.0.3)

As for cropping the PDFs, pdfscissors is free and nice but will leave a watermark at the first page and the last page (*edit, 13 Oct 2011: the watermark is removed in 0.0.2). PDFill PDF Tools (8.0) somehow produce files that Nook has trouble determining the borders. pdfcrop script is another option. (edit: Briss also works—thanks Ke Wu for pointing it out)

(edit: Documents made with LaTeX do not look so good because the Computer Modern Roman font does not look good on screen—the strokes tend to be thin.)

Instead of making a lot of edits there’s more comments here.
