The Web As Weapon

Will the networked world become a new digital battleground?

This is part of IEEE Spectrum's special report: Always On: Living in a Networked World

This fall, as tensions in the Middle East erupted into vicious street fighting, a different sort of pitched battle was being waged behind the scenes. With all the fervor of their comrades in arms, computer-savvy patriots on both sides managed to infiltrate or disable enemy Web servers. And so the Hezbollah site was reprogrammed to play the Israeli national anthem, while Israeli government sites were slowed to a crawl by wave upon wave of hostile e-mail.

Hi-fi, Radio, and Retro: The DIY Projects Spectrum Readers Love

They also really like Lego and hacking pretty much everything

Here are some of your favorite Hands On projects: An inexpensive but high-quality DIY audio amplifier (A) and its Web-enabled successor (B); an Arduino-powered replica of the groundbreaking Altair 8800 (C); a Raspberry Pi–powered color mechanical television (D); and (E), a home computer built with just five digital chips that uses an old hack to create an analog video signal.

This month we’re celebrating the launch of our second PDF collection of Hands On articles, which IEEE members can download from IEEE Spectrum’s website and share with friends. So we thought we’d take a look at the relative popularity of Hands On articles published over the last five years and share the top 15 projects our website visitors found most interesting.

Just to give a little peek behind our analytics curtain, the measure of popularity Spectrum’s editors use is “total engaged minutes,” or TEM, which combines page views of articles with how long visitors spend reading them. We use TEM because we’re not terribly interested in grabbing folks with a clickbait headline, only for them to bounce out before they’ve finished reading the first paragraph.

Sleep Can Keep AI From Catastrophic Forgetting

New data-replay strategy prevents AI amnesia

Neural networks can achieve superhuman performance in many tasks, but these AI systems can suddenly and completely forget what they have learned if asked to absorb new memories. Now a new study reveals a novel way for neural networks to undergo sleep-like phases and help prevent such amnesia.

A major challenge that artificial neural networks face is "catastrophic forgetting." When they learn a new task, they have an unfortunate tendency to abruptly and entirely forget what they previously learned. Essentially, they overwrite past data with new knowledge.
