Submission + - Robinhood places 1 share buy limit on AMD (hothardware.com) 1

SpankiMonki writes: No, that's not a typo. It's not AMC the theater chain, it's AMD the chipmaker. AMD, the company whose profits are up 52% over the last year, and who is looking at a very bright future according to most analysts.

AMD Caught In WallStreetBets Drama As Shady Robinhood Dares To Limit Trading


On Thursday and Friday, Robinhood limited its users to purchasing just a single share of AMD. As you might expect, there was an immediate outcry about this turn of events. Unlike GameStop, or many of the other companies that were targeted by Robinhood, AMD actually has solid financial footing and is on a significant organic growth trajectory.

In fact, AMD witnessed a 45 percent uplift in revenue year-over-year for 2020, and a 52 percent uplift in full-year profit to $4.35 billion. All of AMD's business units were on fire, from standalone Ryzen and Radeon GPUs, to its semi-custom chips used in the PlayStation 5 and Xbox Series S/X, to its EPYC data center processors. Despite the big earnings win, AMD was greeted with a dramatic drop in its share price last week, and what appears to be subsequent interference from Robinhood.


Submission + - New fusion rocket thruster concept uses magnetic fields (sky.com)

schwit1 writes: Dr Fatima Ebrahimi from the US Department of Energy's Princeton Plasma Physics Laboratory (PPPL) has invented a new fusion rocket thruster concept that performs much better than existing plasma thrusters in computer simulations — generating exhaust with velocities of hundreds of kilometres per second, 10 times faster than those of other thrusters.

While current space-proven plasma propulsion engines use electric fields to propel the particles, the new rocket design would accelerate them using magnetic reconnection.

This process is found throughout the universe but is most observable on the surface of the sun. When magnetic field lines converge there, before separating and then reconnect again, they produce an enormous amount of energy.

Red states also have fewer cities and lower population density, which is what people need to survive if they're going to be homeless, whether it be through panhandling or shelters and other support structures. Not many homeless people can survive in the Rockies. It's not about red government vs. blue government, it's about urban environments being blue and so more urban environment means you are a "blue state."

Redbox costs two bucks a day, and only carries AAA titles. If you're the kind of guy that only plays CoD, great, that works for you. If you're like me and loved the living hell out of Deadlight and Mark of the Ninja and other indie/oddball titles and want everyone else to try them, or even would rather just play games for free instead of renting them, it kind of sucks that they killed that aspect of their plan.

My statement above wasn't about arguing which platform is best, or even arguing that Microsoft's E3 plan was overall a good thing. It was about the fact that MS was trying something new and interesting along with their broken DRM scheme, and killed the interesting part along with the horrible part.

Same(ish) CPU
More modern GPU of same brand with more cores
Same amount of RAM, more bandwidth from GDDR5, but no SRAM on-die

In other words, PS4=more graphical power, less effective memory management overall. So PS4 is at best slightly superior to XB1, not "vastly."

And of course, one other thing to consider is that the power and heat management of the XB1 is better than the PS4 - which no one will care about until they remember RRoD and YLoD issues stemming directly from heat in almost all cases.

Now if by "vastly" better you meant in terms of the original DRM scheme implementations, then no disagreement here.

They killed the "Family" sharing plan entirely, whether you bought the game from the online shop or on disc.

These changes will impact some of the scenarios we previously announced for Xbox One. The sharing of games will work as it does today, you will simply share the disc. Downloaded titles cannot be shared or resold. Also, similar to today, playing disc based games will require that the disc be in the tray.

Personally, I think they should have kept the digital sharing plan - it was the one thing that was significantly better than what the PS4 or WiiU offers, and I think would have done a lot to bring back the people they alienated last week. Oh, well.
