NAOMI Mac OS
SignStream® version 3 !*
A new Java version of SignStream® is now available !
Get Version 3.3 - an update released in July of 2020.
Designed to facilitate linguistic annotation and analysis of video data from American Sign Language (ASL).
System requirements:
- Mac OS 10.8 through 10.14. Important warning:SignStream® is not compatible with the latest version of the Mac operating system. We hope to resolve compatibility issues in the near future, but as of now, SignStream® will not work with Mac OS versions 10.15 or later.
- Java 6 (legacy) is also required; you can download that from https://support.apple.com/kb/dl1572?locale=en_US.
Download the latest version (3.3) of the software - and follow the instructions for installation carefully.

Video codecs that work with the application; if your video is in a different format, you should first convert it to one of these:
- MPEG-4 (.mp4)
- AVC1 (.mp4)
- MPEG-4 (.mov)
- H.264 (.mov)

Once the ASLLRP Sign Bank has been installed, SignStream® will check for Sign Bank updates each time SignStream® is launched. If an update is needed, a terminal window will open to enable the update to occur, after which the program itself will launch.
The Data Access Interface (DAI) <http://secrets.rutgers.edu/dai/queryPages/> allows browsing, search, and download of ASL video data (linguistically annotated through use of SignStream®), for (a) the National Center for Sign Language and Gesture Resources (NCSLGR) corpus; and (b) ~10,000 examples (over 4,000 distinct signs) in citation form, as part of the American Sign Language Lexicon Video Dataset (ASLLVD), which forms the basis for the initial ASLLRP Sign Bank (see above).

Ever notice how people texting at night have that eerie blue glow?
Or wake up ready to write down the Next Great Idea, and get blinded by your computer screen?
During the day, computer screens look good—they're designed to look like the sun. But, at 9PM, 10PM, or 3AM, you probably shouldn't be looking at the sun.
f.lux
f.lux fixes this: it makes the color of your computer's display adapt to the time of day, warm at night and like sunlight during the day.
It's even possible that you're staying up too late because of your computer. You could use f.lux because it makes you sleep better, or you could just use it just because it makes your computer look better.
Free for macOS
Free on Windows, for personal use

f.lux makes your computer screen look like the room you're in, all the time. When the sun sets, it makes your computer look like your indoor lights. In the morning, it makes things look like sunlight again.
Tell f.lux what kind of lighting you have, and where you live. Then forget about it. f.lux will do the rest, automatically.
