How to Enable and Use Back Tap on iPhone for Screenshots, Opening an App, running Shortcuts, or other Features

Date Published: Sat, 20 Feb 2021 11:28:50 +0200

Back Tap is an accessibility-related functionality, and Apple has designed it in a way for anyone to take advantage of. Once enabled, Back Tap allows you to bind various iPhone features such as Siri, the Control Center, and even shortcuts. As its name implies, you can then enable it by tapping the back of the device. Back Tap also relies on the built-in accelerometer, so you can set it up on any iPhone that's capable of running iOS 14.

You have the option of binding a double and a triple tap to various iPhone features. I am using screenshot for one of those but you can even bind to Shortcuts scripts as well.

To infinity and beyond: Linux and open-source goes to Mars powering the rover's companion drone helicopter

Date Published: Sat, 20 Feb 2021 11:05:47 +0200

Perseverance hit Mars' atmosphere at almost 12,000 miles per hour (19,312 kilometers per hour) and a mere seven minutes later NASA landed its latest Mars rover softly and safely. Onboard the one-ton mobile science lab is its tiny flying companion, the drone helicopter Ingenuity. If all goes well, the four-pound (1.8 kilograms) Ingenuity will be the first vehicle to ever fly on another world. At 11-light minutes from Earth, no one will fly the dual-propped Ingenuity with a drone controller. Instead, it will fly itself using a combination of Linux and a NASA-built program based on the Jet Propulsion Laboratory's (JPL) open-source F´ (pronounced F prime) framework.

There are, of course, many other open-source NASA programs. There are more than 500 NASA Open Source 3.0 license software projects. Long before the concepts of free software and open-source had been articulated, NASA shared much of its code freely under the COSMIC program. NASA has long used Linux both on the International Space Station (ISS). Linux's path to supercomputer domination started at NASA's Goddard Space Flight Center (GSFC) with the first Beowulf supercomputer.

South Africa will use its abundant platinum deposits to start making hydrogen fuel cells to provide clean energy

Date Published: Fri, 19 Feb 2021 18:44:35 +0200

After over a decade of research and development around hydrogen fuel and lithium battery storage technologies, President Cyril Ramaphosa says South Africa is now ready to manufacture and commercialise hydrogen fuels technology.

“Hydrogen and fuel cell technologies, which use platinum, offer an alternative source of clean electricity, while hydrogen allows for energy to be stored and delivered in a usable form,” he said.

Which is great news as the demand will be high both within SA and from outside.

Viet Nam has installed 6 coal plants’ worth of solar in a year

Date Published: Fri, 19 Feb 2021 13:41:13 +0200

Viet Nam offered generous incentives to households and businesses to install rooftop solar last year. By the time the scheme ended, 9.3 gigawatts of extra generating capacity had been added – equivalent to six coal-fired plants.

The country, which has previously been heavily dependent on coal for electricity generation, now has more than 101,000 rooftop installations on homes, offices and factories, creating a 25-fold increase in its solar generating capacity in just one year.

A key feature of the incentive scheme was a generous feed-in tariff for solar users to sell surplus power to the national electricity grid at a price guaranteed for 20 years. Viet Nam favoured rooftop solar because it does not use scarce land or require new transmission lines.

OpenRGB: Open Source RGB Lighting Control For Keyboards, Fans, Mice And Much More for Windows and Linux

Date Published: Fri, 19 Feb 2021 13:14:44 +0200

Usually each component manufacturer has their own software for controlling RGB lights, with some requiring an online account to function. For Linux users, even that is not usually available since most of these applications are proprietary and Windows only. This is where OpenRGB comes in. OpenRGB is a free and open source application to control RGB lighting for a multitude of devices, independent of the manufacturer.

It's working on my Manjaro Linux using the AppImage executable. It was not detecting my USB devices though until I ran it with admin privileges. So the keyboard is working fine, but does seem I may have to patch the kernel for the fans and CPU coolers to work. That always requires some caution so don't just jump in and take that step until doing some homework on their Gitlab issues forum.

With an Upgraded Color E Ink Screen, the PocketBook Color Could Be the Perfect E-Reader for Comic Book Fans

Date Published: Thu, 18 Feb 2021 18:30:30 +0200

The InkPad’s larger screen, which makes it look more like an iPad Mini and less like an Amazon Kindle, is what’s going to draw more people to color E-Ink devices because it allows documents that can’t easily be resized (change the size of text and it can reflow to fit a screen, but that’s not an option with illustrations) to be enjoyed without having to constantly zoom in and out to make text legible. On a device that’s powered by a 1 GHz process and just 1 GB of RAM, zooming and panning large documents isn’t the smoothest of experiences, so while the InkPad isn’t as pocketable as the original PocketBook Color, the actual reading experience should be much improved.

Every new product (colour e Ink in this case) needs an iteration or two to get to where it needs to be. Despite what many claim about iPads etc there is something to be said for a reading device with weeks of battery life and the ability to be easily readable in bright sunlight. It's a pity though that it costs $329 as that is a bit pricey still.

When we reviewed the PocketBook Color last year, we loved the device and the fact that true e-readers could finally display color, but its six-inch screen made it hard to use for reading comic books and magazines which work much better on tablets. The new PocketBook InkPad Color tries to remedy that with a larger 7.8-inch screen that uses E-Ink’s next-generation color electronic paper technology.

Steam’s biggest new hit is a Viking survival game that struck like a bolt from the blue

Date Published: Thu, 18 Feb 2021 18:16:50 +0200

The Steam Early Access title sold 2 million copies in 13 days, and it’s not hard to see why... except I'm not sure why? I do like though that it's an indie game, and I'm really happy for them.

University of California (UC) San Diego designs new wearable all-in-one health monitor patch attaches to the neck and can report on users' blood pressure, diabetes and other chronic condition

Date Published: Wed, 17 Feb 2021 12:17:03 +0200

Engineers have developed a stretchy skin patch for the neck that provides all-in-one health monitoring capabilities. The innovation can track blood pressure, heart rate and measure glucose levels, but is the first to monitor cardiovascular signals and biochemical levels.

'It would also serve as a great tool for remote patient monitoring, especially during the COVID-19 pandemic when people are minimizing in-person visits to the clinic.'
This is not really intended for home or casual use at all, but more as an extension of existing medical treatment and monitoring, but it shows again what is becoming possible with non-invasive monitoring technology.
