SpaceX filed a request with the FCC on Friday seeking approval to put a constellation of 1 million data centersatellites into orbit.
While the FCC is unlikely to approve a network that expansive, SpaceX’s strategy has been to request approval for unrealistically large numbers of satellites as a starting point for negotiations.
The filing proposes establishing a network of solar-powered data centers in low Earth orbit that communicate with one another via lasers. The filling speak…

SpaceX wants to put 1 million solar-powered data centers into orbit
SpaceX claims putting data centers in orbit will be cheaper and more environmentally friendly than building them on land.

i'm not wild about this LP — it's ok, but maybe i should make space on my shelf and spin something new (i mean old) in its place
i paid six bucks for it a few years ago ... i'll bet i could still get a couple bucks for it!
it bears mentioning that paul chambers went to my high school
tommy flanagan is also from detroit, but he didn't go to cass tech, he graduated from northern (as did my father before him)

Abstract: We consider the first-order autonomous ordinary differential equation \[ \mathbf{x}' = \mathbf{f}(\mathbf{x}), \] where $\mathbf{f} : \mathbb{R}^n \to \mathbb{R}^n$ is locally Lipschitz. For a box $B_0 \subseteq \mathbb{R}^n$ and $h > 0$, we denote by $\mathrm{IVP}_{\mathbf{f}}(B_0,h)$ the set of solutions $\mathbf{x} : [0,h] \to \mathbb{R}^n$ satisfying \[ \mathbf{x}'(t) = \mathbf{f}(\mathbf{x}(t)), \qquad \mathbf{x}(0) \in B_0 . \]
We present a complete validated algorithm for the following \emph{End Cover Problem}: given $(\mathbf{f}, B_0, \varepsilon, h)$, compute a finite set $\mathcal{C}$ of boxes such that \[ \mathrm{End}_{\mathbf{f}}(B_0,h) \;\subseteq\; \bigcup_{B \in \mathcal{C}} B \;\subseteq\; \mathrm{End}_{\mathbf{f}}(B_0,h) \oplus [-\varepsilon,\varepsilon]^n , \] where \[ \mathrm{End}_{\mathbf{f}}(B_0,h) = \left\{ \mathbf{x}(h) : \mathbf{x} \in \mathrm{IVP}_{\mathbf{f}}(B_0,h) \right\}. \]
Moreover, we provide a complexity analysis of our algorithm and introduce a novel technique for computing the end cover $\mathcal{C}$ based on covering the boundary of $\mathrm{End}_{\mathbf{f}}(B_0,h)$. Finally, we present experimental results demonstrating the practicality of our approach.
