Digital Kitchen Spoon Makes Weighing Your Ingredients a Snap

There seem to be two camps when it comes to recipes: those based on volume-based measurements, and those based on the weight of ingredients. Gravimetric measurements have the advantage of …read more Continue reading Digital Kitchen Spoon Makes Weighing Your Ingredients a Snap

Botnet-led DDoS Attacks Are Hitting Record Intensities. Imperva is Mitigating All of Them.

DDoS attacks are usually ranked by the amount of bandwidth involved, such as the 2018 GitHub attack that peaked at 1.35 Terabits per second and is often cited as the largest DDoS attack ever. From Imperva’s long history of successfully mitigating… Continue reading Botnet-led DDoS Attacks Are Hitting Record Intensities. Imperva is Mitigating All of Them.

A 3D Scanner that Archimedes Could Get Behind

3D-scanning seems like a straightforward process — put the subject inside a motion control gantry, bounce light off the surface, measure the reflections, and do some math to reconstruct the shape in three dimensions. But traditional 3D-scanning isn’t good for subjects with complex topologies and lots of nooks and crannies that light can’t get to. Which is why volumetric 3D-scanning could become an important tool someday.

As the name implies, volumetric scanning relies on measuring the change in volume of a medium as an object is moved through it. In the case of [Kfir Aberman] and [Oren Katzir]’s “dip scanning” …read more

All Your Displays Are Belong to Us

Artist and Hackaday reader [Blair Neal] wrote in with his incredible compendium of “alternative” displays. (Here as PDF.) From Pepper’s Ghost to POV, he’s got it all covered, with emphasis on their uses in art.

There’s an especially large focus on 3D displays. Projecting onto screens, droplets of water, spinning objects, and even plasma combustion are covered. But so are the funny physical displays: flip-dots, pin-cushions, and even servo-driven “pixels”.

We really liked the section on LCDs with modified polarization layers — we’ve seen some cool hacks using that gimmick, but the art pieces he dredged up look even better. …read more
