Compal’s Airttach Laptop May Be The Best Triple-Screen Concept We’ve Seen Yet
When on the go with a laptop, one of the biggest complaints tends to be a lack of screen real estate, especially for people who are used to multiple displays. In response to these user requirements, companies have created concept products such as Razer’s triple-display Project Valerie gaming notebook concept we saw at CES 2017. Ultimately,

Kali Linux 2021.1 Released: Tweaked DEs and Terminals, New Tools, Silicon Macs
Slashdot reader Finuz writes: Offensive Security has released Kali Linux 2021.1, the latest version of its popular open source penetration testing platform. You can download it or upgrade to it. Kali NetHunter, the distro’s mobile pentesting platform, now has an upgraded BusyBox engine and tools updated to the latest version (or, in some cases, completely rewritten). There are two new Kali ARM images: one that can be used with VMs on Apple Silicon Macs (Apple M1) and the other for the Raspberry Pi 400’s wireless card.

Raven the Science Maven Has a Message for Aspiring STEM Workers: Be Your Unapologetic Self
Diversity has always been an issue in STEM.

Black and Hispanic workers are underrepresented in STEM, per the report,…

Red Hat Introduces Free RHEL for Open-Source Organizations
ZDNet brings an update about the future of Red Hat Enterprise Linux:
When Red Hat, CentOS’s Linux parent company, announced it was “shifting focus from CentOS Linux, the rebuild of Red Hat Enterprise Linux (RHEL), to CentOS Stream,” CentOS users were not happy. Now, in an effort to mollify them and to keep its promise to open-source organizations, Red Hat is introducing a new, free RHEL for Open Source Infrastructure. If your non-profit organization, project, standard body, or foundation is “engaged with open source,” you can get a free RHEL subscription via this program. Earlier this year, Red Hat introduced no-cost RHEL for small production workloads and for customer development teams…
Jason Brooks, a Red Hat Open Source Program Office Manager explained:
Supporting the open-source software ecosystem is a core objective for Red Hat… We know that we are part of a larger, interdependent ecosystem that we benefit from and which we do our best to foster and support. This support comes in many forms, but often includes helping open source software projects, foundations, and standards bodies access enterprise technologies for development and testing.
We frequently provide no-cost access to RHEL to these groups, but the process isn’t as formalized, consistent, accessible, or transparent as we’d like it to be. With the announcement that we will be shifting our resources to CentOS Stream at the end of 2021, we want to make sure that those organizations engaged with open source have access to RHEL as they build and test the future of open-source software…
The GNOME Foundation’s executive director Neil McGovern, said:
As a non-profit, we rely on donations to help us achieve our goal of a world where everyone is empowered by technology they can trust. RHEL subscriptions are an essential part of this. With full operating system management and security updates, we can concentrate on the services we provide to GNOME users and developers without having to worry about the underlying systems. Red Hat has generously provided these services to GNOME at zero cost for years, and we look forward to continuing our relationship for a long time to come.
GNOME is also the default desktop in RHEL Workstation.

Aptera Promises The World's First Mass-Produced Solar Car This Year
California-based Aptera Motors “is rolling out the first mass-produced solar car this year,” reports the Washington Post, after successfully crowdfunding a restart of their development effort:
It’s a three-wheel, ultra-aerodynamic electric vehicle covered in 34 square feet of solar cells. The car is so efficient that, on a clear day, those cells alone could provide enough energy to drive about 40 miles — more than twice the distance of the average American’s commute.
The Aptera must undergo safety tests before the company can begin distribution, which it hopes to do by the end of this year. Even then, it’s not clear that consumers will want to buy something that looks like a cross between the Batmobile and a beetle. The shadow of an initial attempt, which ended in bankruptcy, hangs over the founders as they gear up to launch their new product. But the Aptera’s creators, Chris Anthony and Steve Fambro, think the world needs a car like theirs. Transportation is the largest source of planet-warming pollution in the United States. The Biden administration has made it a priority to reduce vehicle emissions, and several major automakers have pledged to phase out cars and light trucks with internal combustion engines.
After years of dreaming, maybe the time for driving on sunshine is finally here.
The Post also reports that 7,500 people have already put down a deposit for the two-seater car (which retails for $25,900). It can be charged just by plugging it into an electric outlet, the Post notes, while its creators claim that their car is four times more efficient than the average electric vehicle. “At least 90% of the power produced by the Aptera’s solar panels goes toward making the vehicle move, the company says.”
“Its extreme efficiency means the car can go 150 miles after just 15 minutes at an ordinary charging station.”

Atlantic currents seem to have started fading last century

The major currents in the Atlantic Ocean help control the climate by moving warm surface waters north and south from the equator, with colder deep water pushing back toward the equator from the poles. The presence of that warm surface water plays a key role in moderating the climate in the North Atlantic, giving places like the UK a far more moderate climate than its location—the equivalent of northern Ontario—would otherwise dictate.
But the temperature differences that drive that flow are expected to fade as our climate continues to warm. A bit over a decade ago, measurements of the currents seemed to be indicating that temperatures were dropping, suggesting that we might be seeing these predictions come to pass. But a few years later, it became clear that there was just too much year-to-year variation for us to tell.
Over time, however, researchers have figured out ways of getting indirect measures of the currents, using material that is influenced by the strengths of the water’s flow. These measures have now let us look back on the current’s behavior over the past several centuries. And the results confirm that the strength of the currents has dropped dramatically over the last century.
