A picture might be worth a thousand words, but scrolling through 75,052 icons is a fun and nostalgic way to explore retro apps! The Visual Catalog of Retro Macintosh Software showcases an (almost) endless wall of icons culled from Macintosh CD-ROMs from the 80s and 90s, from the days before megapixels, when 32x32 pixels were enough for everybody!

I live in a condominium where I get interference from my neighbors' wifi.
I understand that 1, 6 and 11 are the only non-overlapping
wifi channels, but how does this translate into real-life best practices?
- When you must overlap, is there a "good" way to do it?
With nine access points, for example, is it better to have three APs each
on channels 1, 6 and 11, so that each completely
overlaps with only two others. Or is it best to distribute those
APs across nine channels such that they only partially
overlaps others (but potentially overlap more APs in total)?
- Do use patterns affect interference? For example, is it
best to overlap a channel with multiple APs that rarely
transfer data, or to share a channel with one person who downloads
torrents 24/7?
- Does maximum data rate affect interference or robustness to
interference? I found out by accident that setting my access point
to "802.11b only" mode appeared to give me a vastly more reliable
connection that leaving it in "mixed 802.11b/g". Is this a fluke or
does transmitting at 10 Mbps, when everyone else is using
54 Mbps (for their 3 Mbps DSL pipes!), give you a true advantage?

An interesting look at Ray Kurzweil's predictions for 2009, from a decade ago. He was dead on in predicting the ubiquity of portable computers, wireless, the emergency of "digital" objects, and the rise of privacy concerns. He was a little optimistic in certain areas, predicting the demise of rotating storage and the ubiquity of digital paper a bit earlier than it appears it will actually happen. As it comes to human-computer speech interfaces, thought, he seems to be way off.
