<p>Modern "GPUs" have the ability to scan out from multiple buffers at the same time and do rectangular compositing during the scan out -- basically like a few giant sprites.  It's got absolutely nothing to do with normal GPU work.  Zero.<p>It lets a few unobstructed windows do animation without having to involve the compositor => lower latency AND lower energy use.  They do NOT have to be full screen at all.<p>Oh, and they can also handle framebuffer formats that aren't RGB.  This is very useful for video, as the natural format there is YUV or something similar.  The YUV => RGB conversion step becomes unnecessary.</p>

<p>> had essentially their own processors to handle this stuff<p>Most of the benefit came from the sound card doing DMA from a memory buffer instead of using a high-frequency interrupt to have the CPU give it sound samples one or two bytes at a time (fetched from the very same memory buffer(s)).<p>More sophisticated cards could also do mixing of several sounds in "hardware" (usually by having their own little CPU do the work) instead of having the main CPU doing the mixing.  Some of them could even play the constituent sounds at different speeds (Gravis Ultra Sound and Midi cards but the Midi cards usually had fixed sound samples).  This mattered for more sophisticated game audio for a few years until x86 performance improvements made it irrelevant.  DMA is still crucial.</p>

<p>She would need the backing of both the European Council and the European Parliament to get a third term.  That is extremely unlikely to happen.  Moreover, the European Parliament can kick her out at any point if it really wants to.<p>There are also hard limits on what she can do as president.  Brussels doesn't rule over the member states like Beijing rules over the provinces (Chinese + "acquired" ones).  Most things need the backing of the Council (= the member states) + the member states can drag things out at home if they want to.  The EU doesn't have anything like the US National Guard that can be used in member states to force them to comply (possibly against state laws and state constitutions).<p>The European Union is the consensus making cooperation machine many European countries have chosen to use and die Uschi is only in charge of one component of that machine.<p>Doesn't seem very rulery to me.</p>

<p>1959 was a long time ago.<p>Should we (the EU?) have sent weapons to the Venezuelan opposition in 1999?  When exactly did Chávez become a dictator?  He was clearly not a democrat (coup attempt in 1992) but I think it would have been premature and unlikely to have had good outcomes if we had done it in 1999 or 2000 (he was democratically elected both times).  He was obviously a dictator when he died in 2013 but a large part of the Venezuelan population still hadn't cottoned on to it or they thought it was great.<p>Iran was similar.  The crazies were quite popular in 1979.</p>

<p>No, the money spent per pupil has a tiny effect (at best!) on outcomes.<p>There are also massive transfers involved (and the US has had them for at least twenty years) so the property taxes (in the US) have little to do with how much money schools have per pupil.</p>

<p>Often enough that high house prices can keep your kids away from most bad kids.  I think it's a crude mechanism that still allows too many bad kids in and keeps a lot of good kids out.  I don't like it.  It's also the best available mechanism in many countries.</p>

<p>>  If schools have lower taxes, their ability to attract good educators for children is reduced.<p>"Good schools" are mostly about avoiding bad kids and bad parents.  Expensive homes (without Section 8 or equivalent in the neighbourhood) is a feature, as it keeps most of them away.  It's not a good way of doing it -- it excludes lots of perfectly good kids and parents and it is really expensive.  It's just the best way available to most people in the West.</p>

<p>> in the times of very anemic compilers<p>These days, it's mostly taken as an invitation by very <i>powerful</i> compilers to sometimes do heroic optimizations (that we like) -- and sometimes screw us over in really obscure ways (which we don't like).  We would really like to keep their ability to perform heroic optimizations and that's why there's so much pushback against eliminating undefined behaviour.</p>
