Google Helps Fight Child Porn

By DT Staff Published October 25, 2009

Google Helps Fight Child Porn Google might have its critics from time to time, but company employees can also do a lot of good. A group of them have taken a program originally developed totrack copyrighted videos posted on YouTube without permission and adapted it in order to search for patterns in abuse images online and also track child predators. The work has been done forthe National Center for Missing and Exploited Children (NCMEC) and was done on the company’s “20% time,” under which employees are allowedto give one-fifth of their time to projects they start, whether they’re for the company or for good causes. The big problem for analysts has been the sheer amount of data; in the lastsix years the NCMEC has had to go through 13 million images and videos of child abuse, with five million in the last year alone. Google’s tools will greatly speed up that analysis. Google research scientist Shumeet Baluja said in a blog posting, “With these tools, analysts will be able to more quickly and easilysearch NCMEC’s large information systems to sort and identify files that contain images of child pornography. In addition, a new video tool we built streamlines analysts’ review of videosnippets,” and added, "You always hope that your work will eventually be used to do some good in the world, and this was an amazing chance to make that hope real."

AI mode in Google Search

There’s no such thing as a free recommendation. Google’s latest policy tweak is a clear reminder. Google has long promised that your Gmail, Drive, and Google Photos content never helps it personalize ads.

However, since October 16, 2026, its privacy policy adds a catch. The promise lapses if you let other ad-showing Google services use that content. That means using Personal Intelligence, an opt-in tool that lets Google’s AI search read your connected apps, does exactly that (via Google).

OpenAI is locking its most advanced AI models offline after a string of security scares

OpenAI’s fake internet is a safety fix and an admission.

Part of me is relieved that an AI lab is hitting the brakes. The other part wishes it hadn’t taken real incidents to get there.

OpenAI said Friday that its most advanced models will now train without live internet access. Instead, they’ll practice on a cached, simulated copy of the web.

Your Windows touchpad is about to make scrolling long pages way less tiring

Three touchpad tricks that make long documents feel a lot shorter.

Windows new scrolling feature

Today I learned about a touchpad tip that I think every Windows laptop user should know. Microsoft shared it as its Friday Windows tip of the day, and it’s all about scrolling.

If you read long documents, browse webpages, or write code on a Windows laptop, you know the drill. You swipe, lift your fingers, and swipe again until you reach the part you need. Microsoft has three touchpad features that cut down on all that swiping.
