Acoustic Weapon That Annoys You Into Stop Talking

The U.S. Navy have created a crowd control device that can record speech and project it back at a target within milliseconds, which results in so much confusion that the target person stops talking. The acoustic hailing and disruption (AHAD) device can also project sound at a wall so that it seem the sound originates from the wall.

Higher Order Interactions & Hypergraphs

#279

Quanta Magazine published an interesting article on the new frontiers of graph theory within computer science where big data is starting the stretch the capabilities of regular graphs in favour of, in some circumstances, hyper-graphs and higher order interactions to better model and analyse relationships within the highly connected data.

Make An Old iPhone Run Faster

#278

If you have an old iPhone (7+), you can turn off Apple's built-in performance degradation by setting the device location to France. Apple had to pay a fine & stop the policy in France for slowing down older phones, whereas in other countries they were able to avoid this by reducing the price of replacement batteries.

Fitness Trackers & COVID-19 Recovery

#271

A study of freely volunteered data from fitness trackers of 243 people with COVID was compared with the tracker data of 641 sick people without COVID. The study showed that it takes the body two to three months to recover from COVID-19. Resting heart rate takes the longest to return to baseline after two to three months, with step count returning to normal levels at around day 24.

The Inverse Conway Law

#270

Melvin Conway stated in 1968 that "Any organisation that designs a system (defined broadly) will produce a design whose structure is a copy of the organisation’s communication structure.". Andreas Wolff published an interesting post on CTO Craft about using an inverse Conway Law when designing the struture of an organisation.

Robotic Third Thumb

#265

Researchers at UCL conducted a study where participants trained themselves to use a robotic third thumb which was desisgned by the Royal College of Art. Users of the thrid thumb control its movement using their toes. The UCL study measured brain activity of participants after time using the thumb and found that the brain's representation of the hand had changed.
