Why is self hosting exactly? §
Self hosting is about freedom, you can choose what server you want to run, which version, which features and which configuration you want. If you self host at home, You can also pick the hardware to match your needs (more Ram ? More Disk? RAID?).
Self hosting is not a perfect solution, you have to buy the hardware, replace faulty components, do the system maintenance to keep the software part alive.
Maxwell's equations and general relativity—what are these all about?
Maxwell's equations are the key linear partial differential equations that describe classical electromagnetism. The equations relate the electromagnetic field to currents and charges. On the other hand, in general relativity, the Einstein field equation is a set of nonlinear partial differential equations describing how the metric of spacetime evolves, given some conditions, such as mass density in the spacetime. Both equations are ultimately of second order, if seen properly.
Therefore, we thought that perhaps we are talking about the same governing equation, which could describe both electromagnetism and gravitation. Indeed, it becomes clear that Maxwell's equations hide inside the Einstein field equations of general relativity. The metric tensor of spacetime tells us how lengths determine in spacetime. The metric tensor also thus determines the curvature properties of spacetime. Curvature is what we feel as "force." In addition, energy and curvature relate to each other through the Einstein field equations. Test particles follow what are called geodesics—the shortest paths in the spacetime.
For the past few years, we at Damn Interesting have been hearing from scores of long-time fans who were under the mistaken impression that we had ceased all operations years ago. These fans are typically delighted to hear that a) we are still writing and podcasting; and b) there is a wealth of new content since they last visited. When we ask them what caused the assumption of our demise, they invariably cite the fact that our posts disappeared from their Facebook news feeds.
This trend roughly coincides with Facebook’s introduction of “boosting” for pages; in this new model, according to the stats we can see, Facebook stopped showing our posts to approximately 94% of our followers, demanding a fee to “boost” each post into an ad, which would make it visible to more of our audience. We lost contact with tens of thousands of fans practically overnight. We don’t mind paying for a service if it is valuable, but we absolutely don’t want to reach our audience by buying ad space on Facebook. Yuck. But no other option is given to reach the many people who previously followed our posts, and who presumably want to continue to do so.
We established our Facebook page in 2008 as the fledgling social media site was gaining in currency, and we continued to maintain our page on the side, mostly as an afterthought. In the intervening years Facebook evolved from a dubious curiosity into a megacorporation that is firmly in the service of bad ideas. In a move that feels long overdue, we at Damn Interesting are abandoning all interactions and connections with Facebook.
We really should have done this back when it was revealed that Facebook used the ubiquitous embedded “Like on Facebook” buttons to follow people’s movements around the web without their knowledge or consent. We should have done this when Facebook literally toyed with people’s emotions by showing some people more positive stories in their newsfeeds, and others more negative stories, to see how it would affect their emotional states. We should have done this when it was revealed that Facebook allowed advertisers to target ads to people who expressed interest in topics such as “Jew hater.” We should have done this so many times before.
To the tens of thousands of fans who follow us on Facebook: our sincere apologies. You’re probably not seeing most of our posts there, anyway. For the few who do still see them, we no longer wish to share content on Facebook which might cause people to spend time there. We hope you’ll stay in touch via one of our multiple non-Facebook options
This battery can be used continuously over a multi-day period and will enable a reliable, secure, and fully renewable electric grid year-round,” said Form Energy.
Or as Greg Lydkovsky, global head of R&D at steel giant ArcelorMittal — Form Energy’s latest investor — put it, the technology “holds exciting potential to overcome the intermittent supply of renewable energy”.
Form Energy president and chief operating officer Ted Wiley said: “We’ve completed the science, what’s left to do is scale up from lab-scale prototypes to grid-scale power plants.
“[At full production], the modules will produce electricity for one-tenth the cost of any technology available today for grid storage.”
The battery is said to work through “reversible oxidation of iron”. In discharge mode, thousands of tiny iron pellets are exposed to the air, which makes them rust (ie, the iron turning to iron oxide). When the system is charged with an electric current, the oxygen in the rust is removed, and it reverts back to iron.
Wiley said that a 300MW “pilot” project for Minnesota-based Great River Energy will be commissioned in 2023.
It may be hard to believe, but for much of the time of C++’s original development, it did not have a string class. Writing such a class was somewhat of a rite of passage, and everyone made their own. The reason behind this was partially the prolonged attempt to make a class that was everything for everyone.
On your real ID, the laminate is almost unnoticeable, except for a slight glossy sheen. It ends at the end of the card, although if you look very closely at the edge of the card you can see two or three layers: the laminate, the card stock, and possibly another layer of laminate.
Over the last few years, our team has been exploring how to give industrial robots the ability to sense, learn, and automatically make adjustments as they’re completing tasks, so they work in a wider range of settings and applications. Working in collaboration with teams across Alphabet, and with our partners in real-world manufacturing settings, we’ve been testing software that uses techniques like automated perception, deep learning, reinforcement learning, motion planning, simulation, and force control.
