This morning, the Washington Post published an article that showcased the work of David Shahar and Mark Sayers—two health science researchers from Australia’s University of the Sunshine Coast—who claim that horns are growing from the lower skulls of young people. Shahar and Sayers’s research focuses on enthesophytes, or bits of bone that grow due to some combination of chemical, genetic, environmental, or use factors. There’s also several reasons some people have poor posture that have nothing to do with smartphone use or discipline.

Now comes the interesting news that the European Space Agency is developing a mission called Comet Interceptor, one capable of visiting a long-period comet coming into the inner system from the Oort Cloud, but just as capable of reaching an interstellar visitor. It will be the first spacecraft to visit a truly pristine comet or other interstellar object that is only just starting its journey into the inner Solar System. But ESA is also thinking about interstellar objects like ‘Oumuamua as potential destinations, for the mission has the luxury of being able to choose its target from its stable vantage point at L2.

On the other hand, in a static typed language, a large number of errors are caught early stage in the development process, and static typing usually results in compiled code that executes faster because when the compiler knows the exact data types that are in use, it can produce optimized machine code. Type safety is one of the Rust’s biggest selling point and is the reason Rust topped as most loved language for 3 consecutive years in StackOverflow Surveys. Despite the fact that you’re doing things like manual memory management that you do in C++, Rust has a lot of features and conveniences that almost make it feel like a high-level language.

International NGO Global Witness found that the Taliban earns up to $20m a year from Afghanistan’s lapis mines, lapis lazuli being, as crystal websites explain, one of the best stones for activating psychic abilities. For Wells, the importance of ethical crystal mining is not solely about the impact on the planet, but also on the crystal itself – he believes the mining of a stone affects its healing properties. And rather than directly from mines, or even the factories where the stones are cut and polished, retailers like the Crystal Geode buy from go-betweens, independent traders who sell at touring shows, who, even if they have documentation to prove their supply chain, are disinclined to share it, in part for fear of doing themselves out of a job.

In order to expose a reactive value that can be mutated by a function declared inside , we can use the API:

Calling returns a value wrapper object that contains a single reactive property: . This is what enables composition functions to encapsulate the logic that manages the state while passing the state back to the components as a trackable reference:

Value wrappers can also hold non-primitive values and will make all nested properties reactive. If you want a watcher callback to fire before flush or synchronously, you can use the option:

All current lifecycle hooks will have an equivalent function that can be used inside :

If provided key contains a value wrapper, will also return a value wrapper and the binding will be reactive (i.e. the child will update if ancestor mutates the provided value).

To protest the “heinous act,” commanders Che Guevara, Ramiro Valdés, Camilo Cienfuegos, William Morgan, Eloy Gutiérrez Menoyo, Osvaldo Dorticós Torrado (who would remain the president of Cuba until 1976), and Fidel Castro walked arm in arm down Calle Neptuno, forming a dramatic contrast between the street’s garish neon signs and the plain green of their uniforms—and the sobriety of their mission. Consequently, Hemingway did not abandon his residence or speak out against Fidel Castro, but instead invited him and Che Guevara to go fishing. Watching through their binoculars from the Pilar as Fidel fished and Che read Stendhal’s Le rouge et le noir, Mary and Ernest could hardly believe their eyes when Fidel brought the two marlins in and stopped his assistant from gaffing them until Fidel could grasp the leader himself (rather than the line—just as the rules specified).

U.S. already in recession, Fed will cut rates back to zero: Rosenberg

‘The recession has already started’: David Rosenberg on the U.S. economy

The world’s biggest economy is already in a recession, according to prominent Canadian economist David Rosenberg, who says the U.S. Federal Reserve will begin cutting interest rates all the way back to zero starting this summer. Rosenberg has been calling for a recession in the U.S. in 2019 since late last year. “If you look at household employment, you look at real business sales, you take a look at industrial production, which, by the way, is in a recession, and take a look at organic real income in the U.S. – [it] peaked in December,” said Rosenberg.

Daniel Carey, the president of the pilots’ union at American Airlines, said Boeing’s zeal to minimize pilot-training costs for airlines buying the 737 Max jet contributed to design errors and inadequate training. Pilots complain that Boeing did not tell them about flight software called MCAS until after the October crash of a Lion Air jet in Indonesia. After the Lion Air crash, Boeing sent pilots and airlines a checklist of steps to take if MCAS malfunctioned, including disabling the software and hand-cranking a wheel to manually rotate part of the plane’s tail and point the nose up.

But in contrast to the vast majority of tech companies that go public using an initial public offering, or IPO, Slack will use a direct offering. Direct offerings can involve more risk—although that risk is lessened if a company doesn’t need to raise more cash, is a household name known to retail investors, and has a group of employees and investors clamoring to sell their shares in the stock market. “The success of Spotify’s direct listing was due in part to Spotify being a well-capitalized company with no immediate need to raise additional capital, while also having a large and diverse shareholder base that could provide sufficient supply-side liquidity on the first day of trading, as well as a well-recognized brand name and an easily understood business model,” Latham & Watkins, a law firm that worked with Spotify on its offering, wrote in a subsequent case study.
