New Toy: Kodak Pulse, 7

Maybe http://www.noerenberg.de/hajo/pub/kodak-pulse-picture-frame-server.php.txt is interesting for you (Kodak Pulse picture frame protocol reverse engineered, and some documentation on how to set up your own picture frame server).

On adding alpha channels to JPEG images

weird, it's working on FF2 but not on IE6, but it's probably a matter of your JS code rather than the amazing technique you discovered :
Line: 218
Character: 3
Code: 0
Error Message: Expected identifier, string or number


Thoughts on cross platform and jquery/CSS3/<canvas>

First fly in the ointment: The iPhone 4 renders these gorgeously when zoomed in. The over sampling is beautiful. And you get to look at it for a long time as it more or less freezes MobileSafari when you zoom way in. The refresh after a small pan can be 10 seconds. Double-tapping to get back to a wide zoom frees you from this hell after the next redraw.

Web Storage and privacy.

If you are of a mood to see your own localStorage situation, you could:

for v in ~/Library/Safari/LocalStorage/* ;do 
echo "#### $v ####"
echo "select * from ItemTable;" | sqlite3 $v 
done

Notes on making my EEE PC 900A have a nilfs2 root

Flash erase block sizes are typically 4MB or a near power of two these days - pretty large.

Newer, more advanced SSD controllers such as those on the Intel SSDs make this irrelevant by being intelligent about small writes, but with SSDs like those on the Eee PC, you are stuck with erasing and rewriting entire 4MB or so block for small writes.  Hence why Flash writes are only high performing when writing 4MB or more.

A four day bug

The OpenWRT folks "resolved" this by adding a printk that mentions the FPU emulation is disabled somewhere early in the boot, but not making the kernel option visible or preventing the infinite emulator trap.

At best this will let your kernel tell you "I told you so." after you spend four days debugging.

Debian Lenny and grub with /boot in LVM

You should note that grub-pc for lenny is missing part_msdos.mod and will not install, you need to fetch it from backports to get the file.

Thanks for the info though, it helped me to confirm what I was doing would work before I sent a remote machine through a reboot (I know, dangeous, but couldn't be helped)

Debian Lenny automatic apt updates and downloads

Another good one: To use a cacheing proxy for your packages, add this line to a similar file:

Acquire::http::Proxy "http://YOURHOST:YOURPORT";

This way you don't have to mess with your /etc/apt/sources.list file to make all the proxy changes.

Hi Jim,

I noticed the same problem with the nilfs_cleanerd. Upgrading (from source, in my case) to nilfs-utils 2.0.13 solved the problem for me.

Performance of Some Real and Virtual Machines

I have provoked the computer spirits. The P4 I just benchmarked and decided I could live without has suffered a hard disk failure of its primary disk.

The good news is I don't have to fix it because I now know I can live without it.
