Apple’s iOS 13 comes with some major changes to privacy and security, but it’s also highlighted the data collection practices of firms such as Facebook and Google. I always feel like, somebody's waatching meeeeeeee.

"Introducing 'mesh,' a memory-saving plug-in that could boost phone and computer performance" [^]Quote: Mesh effectively squeezes out these gaps by taking advantage of a hardware feature called "virtual memory" that is supported by almost all modern computers. "The trick is to find chunks of memory that can be interleaved, sort of like when interlocking gears mesh," Berger explains. When Mesh finds these chunks, it can reclaim the memory from one of the chunks by combining the two chunks into just one. "This meshing process works because we only change things in 'physical' memory. From the perspective of the program, which can only see 'virtual' memory, nothing has changed. This is powerful because we can do this for any application automatically."
Quote: Microsoft programmer and distinguished engineer Miguel de Icaza tweeted that Mesh is a "truly inspiring work, with deep impact. A beautiful idea fully developed. What an amazing contribution to the industry."

Would this be the same thing as eliminating fragmented memory (a true concern back in my C++ experience).

Yes, external fragmentation. But at an os / process level.

AIUI it's something of a fake it until you make it approach. The application's address space is still just as fragmented, with all that means for the speed - and in extreme cases possibility - of heap allocations; but by mapping the application address space into hardware address space at a much more fine-grained level than a full memory page the amount of physical memory used is reduced.
While the article doesn't go into great depth about how it works, I assume it requires some level of collaboration between the application's heap allocator and the OS virtual memory drivers.
Did you ever see history portrayed as an old man with a wise brow and pulseless heart, weighing all things in the balance of reason?
Is not rather the genius of history like an eternal, imploring maiden, full of fire, with a burning heart and flaming soul, humanly warm and humanly beautiful?

The paper is here[^]. The source is available here[^]. The paper claims to exceed the old Robson upper bound of O(n2/5(log n)3/5).
You could probably compile this as a native DLL and inject it into all running processes and market it online as a "Super Duper Memory Saver" for only $49.99 ... and it appears that the code would actually work. Hopefully nobody reading this actually does this.
Btw, the combination of algorithms they are presenting will probably have some uses outside of memory allocators... it looks useful for pattern matching too.

To process information, photons must interact. However, these tiny packets of light want nothing to do with each other, each passing by without altering the other. Now, researchers have coaxed photons into interacting with one another with unprecedented efficiency -- a key advance toward realizing long-awaited quantum optics technologies for computing, communication and remote sensing. But choose wisely, for while the true temperature will bring you life, the false temperature will take it from you.

Amazon advertised their job openings extensively, so their high applicant rate is expected. Many of us here probably receive unsolicited job emails from Amazon.

He didn’t want a phone. He really didn’t want a phone. As I protested that he need use it only for calls and texts, he dug in, and became emotional. Please don’t make me get a phone. So I tucked the iPhone 4 in my drawer, assuming he’d come around. Three years later, he still hasn’t. We have developed speed, but we have shut ourselves in. Machinery that gives abundance has left us in want.

Allow me to be controversial for a moment: arbitrary password restrictions on banks such as short max lengths and disallowed characters don't matter. Also, allow me to argue with myself for a moment: banks shouldn't have these restrictions in place anyway. So, 12345 ... 6?

IBM continues to push its quantum computing efforts forward and today announced that it will soon make a 53-qubit quantum computer available to clients of its IBM Q Network. It's still not quite ready for solving anything but toy problems and testing basic algorithms, but ONWARD and UPWARD.
