Phone Filters

We get hundreds of emails a day asking us about filter compatibility and our position on this matter. To clear things up we will provide our official position here:
Parents, bochurim, and yungerleit be warned: A filter is a must for using these 4G phones. A person owning one of these phones without a filter is placing himself/herself in a really really bad situation. For this same reason, we provide kosher apps and not telegram, whatsapp, chrome, youtube, etc. As for which filters work with these apps, and which filter is better or worse, we do not take a position, as things are constantly changing. Please consult with your local TAG, GEDER office, Livigent, etc., to find out what your options are.

6. Legacy and Modern Context

The influence of the 1989 release persists today.

Interactive Physics 1.0 (released in late 1989 for the Apple Macintosh) was the result. It ran on Motorola 68000 processors, measured in kilobytes of RAM, and fit on a single 1.44MB floppy disk. Yet, it featured a rigid body dynamics solver that was years ahead of its time.
