Researchers at Lawrence Berkeley National Laboratory develop a truly recyclable plastic called PDK

Date Published: Tue, 27 Apr 2021 10:58:12 +0200

Researchers from Lawrence Berkeley National Laboratory and the Department of Energy have been studying an enticing, new type of plastic. Called polydiketoenamine, or PDK, it’s an infinitely recyclable material. Literally 100% of it can be reclaimed and reshaped into a new plastic item as many times as a company could want.

“The idea here is that we’re designing new polymers with ease of recycling in mind,” says Corinne Scown, staff scientist and deputy division director at Lawrence Berkeley National Lab.

If we can’t ditch plastic, we can at least make it more recyclable—at least that’s what researchers at Lawrence Berkeley National Laboratory and the Department of Energy are proposing with a new material called PDK.

Linux File System Types Explained, Which One Should You Use - Because Linux gives you more options than just ext4

Date Published: Mon, 26 Apr 2021 21:01:55 +0200

Linux supports a variety of file systems such as ext4, ZFS, XFS, Btrfs, Reiser4, and so on. Different types of file systems solve different kinds of problems and their usage is application specific.

Choosing Linux file system that is appropriate for your application is an important decision. This tutorial describes some of the major Linux file systems and provides recommendations on the right file system to suit your application.

Zoom’s Immersive View could make video calls feel a bit more in-person - Simulating an office (or auditorium) in a Zoom meeting

Date Published: Mon, 26 Apr 2021 16:25:00 +0200

Zoom is rolling out a video background feature called Immersive View that could make video calls feel a bit more like an office meeting — or at least look a lot more like one. Zoom announced the feature last year at its Zoomtopia conference, but now it’s actually available for Free and Pro accounts attending meetings and webinars with up to 25 participants.

Well that certainly ups the level of virtual meetings by another notch.

Keep in touch with Grandma, with this low-tech Raspberry Pi and Telegram Messenger powered interface

Date Published: Mon, 26 Apr 2021 10:30:55 +0200

We have so many options through which to communicate with our friends and relatives during the lockdown, thanks to our smartphones and the number of apps that serve all possible needs. Impressive as they are though, a smartphone is not suitable for everyone.

On the top of the box is a microphone with push-to-talk switch, a small thermal printer, and a set of 1/4″ jack sockets with associated jump lead. Each socket corresponds to a relative, and an audio message to that relative can be posted via Telegram simply by speaking into the microphone with the button pressed. Replies are then printed through the thermal printer. Meanwhile, behind the scenes is a Raspberry Pi holding it all together.

Telegram of course has an easy-to-use API that can facilitate such communications for free, and Python was used for the coding. He has described the process in the Twitter feed but is aiming to make a proper post about it and publish the code to Github.

Redwood Materials recycling facility, which is in Nevada USA recovers 95–98% of critical materials like nickel and cobalt and copper from old batteries

Date Published: Mon, 26 Apr 2021 10:11:19 +0200

JB Straubel, a Tesla co-founder and its former Chief Technological Officer for many years, started Redwood Materials in 2017. He sat down in an interview with CNBC to talk about the importance of battery recycling and shared an inside look at the first Redwood Materials recycling facility, which is in Carson City, Nevada. Straubel pointed out why the materials from old batteries are still as good as new.

Seems the recycling is quite viable as they set their prices by what mines charge to mine the original materials (which is higher). They are mined in countries such as South America and then sent to China to be refined. Then sent to Tesla’s Giga Nevada for cell production at Panasonic.

Valheim gets a new 1.1GB HD Texture Pack (Mod), overhauling most of its textures

Date Published: Sat, 24 Apr 2021 11:31:31 +0200

Modder ‘Willybach’ released earlier this week a 1.1GB HD Texture Pack for Valheim that aims to improve most of its textures. This pack covers most Biomes so far and many Building and Crafting textures. Furthermore, and by using AI techniques, it tries to stay as close to the vanilla textures as possible.

As the modder noted, loading times are drastically reduced, as well as performance. Additionally, this pack does not suffer from an issue that reverted rocks back to their vanilla textures.

It is quite possible to have a quick Traditional Shave, but would you want to?

Date Published: Sat, 24 Apr 2021 10:51:53 +0200

One can do a safety razor shave in about the same time it takes to use a cartridge razor with a can of goo, but many do enjoy taking a little longer with a better quality traditional shave. The little longer is what separates the traditional shaving from its disposable counterpart, and the better quality products do work better given a bit of preparation and time.

The separation is really not that much extra as the traditional shave is like muscle memory, once you have the habit right, it all just happens.
