Technology: “Microsoft Windows Update KB3133977 Is Deadly” http://rgn.bz/8mXK

“Microsoft Warns Windows 7 Has A Serious Problem: Earlier this year Microsoft MSFT warned users that Windows 7 has serious problems. I dismissed its claims as a desperate attempt to shift copies of Windows 10 (and I still do), but now Microsoft has warned of a new serious Windows 7 problem that is very real – even though it makes no sense whatsoever…

In short: Microsoft has made a seemingly small yet completely bizarre tweak to Windows Update on Windows 7 and confirmed it is crippling many users’ PCs. The tweak? It switched the status of Windows 7 update KB3133977 from ‘Optional’ to ‘Recommended’. The bizarre part? Despite acknowledging the problems, Microsoft knew they would occur in advance and it has no plans to do anything about it. Ok, let’s put some meat on these bones.

PCs That Suddenly Won’t Start: It all centers around Asus motherboards. Now 27 years old, Asus is one of the largest PC component makers and supplies motherboards to many of the world’s biggest PC makers. Recently it enabled Secure Boot in UEFI on all its motherboards. This wasn’t a problem for older PCs because Windows 7 didn’t support Secure Boot, that is until KB3133977 came along in March and enabled it.

From article: Should I choose to reclaim my songs via download, the files I would get back would not necessarily be the same as my original files. As a freelance composer, I save WAV files of my own compositions rather than Mp3s. WAV files have about ten times the number of samples, so they just sound better. Since Apple Music does not support WAV files, as they stole my compositions and stored them in their servers, they also converted them to Mp3s or AACs. So not only do I need to keep paying Apple Music just to access my own files, but I have to hear an inferior version of each recording instead of the one I created.
“The software is functioning as intended,” said Amber. “Wait,” I asked, “so it’s supposed to delete my personal files from my internal hard drive without asking my permission?” “Yes,” she replied. …

Yes finally I did something wright
 
The cost of wasting time on commercials removed by Netflix. Think about how much you make an hour and how much this is saving you.
Netflix subscribers may be saving themselves from having to watch 160 hours of commercials a year, according to a new report.

The Challenge Of Proving Black Holes

While the evidence for black holes is pretty conclusive, the extreme nature and odd physics of black holes has encouraged skepticism about their existence in certain circles. While highly dense objects exist, they argue, that doesn’t mean such objects are black holes. On some level they have a point, because there are proposed objects that are black-hole like, but not true black holes, such a gravastar.

A gravastar is an extremely dense object where the behavior of quantum gravity somehow kicks in to prevent the formation of a singularity and event horizon, which are the most contentious aspects of black holes. In some models it is assumed there is a minimum scale (Planck length) where gravity stops functioning in the usual way, while in others dark energy kicks in at small scales to prevent the formation of a true black hole. In either case a gravastar would look quite similar to a black hole.

When gravitational waves were detected this year, it was seen as definitive proof of black holes. The gravitational “chirp” and ringdown detected by LIGO was an exact match of a black hole merger, and even allowed us to determine the masses of the initial and final black holes. It confirmed the existence of gravitational waves, which was the last great prediction of general relativity. Since general relativity predicts black holes quite clearly, the result is pretty definitive. But it is true that black holes should depend upon quantum gravity, which we don’t yet fully understand. If quantum gravity resulted in gravastars, would the LIGO detection look any different? It turns out the answer is yes, but not in a way we can currently detect.

According to the models, gravastars are so dense they have collapsed almost to the point of being a black hole. The merger of two gravastars would still have a chirp and ringdown of gravitational waves. The ringdown of a gravastar merger would differ slightly from that of black holes, but only at the tail of the ringdown. Of course that part of the ringdown seen by LIGO is buried in the background noise of the data. Thus, the gravastar supporters would argue, the LIGO event detected either a gravastar or black hole merger, but can’t distinguish one from the other.

Does that mean the existence of black holes is in limbo? Personally I don’t think so. While gravastar models argue against black holes, there’s no compelling argument for gravastars. While they do resolve certain theoretical conundrums black holes have, gravastar models have problems of their own. Not the least of which is the fact that they depend upon heuristic arguments of quantum gravity that may or may not be valid. So on the whole I don’t find the gravastar model particularly compelling. There’s also the risk of playing the denialism game regarding black holes, where no amount of evidence will ever be seen as sufficient. To be clear, I don’t think gravastar supporters are playing the denialism game. It is good to be skeptical of new work, and the gravastar model is one way to test the limits of our observations.

That’s all part of the challenge of doing science.

Paper: Vitor Cardoso, et al. Is the Gravitational-Wave Ringdown a Probe of the Event Horizon? Phys. Rev. Lett. 116, 171101 (2016) arXiv:1602.07309 [gr-qc]

What if black holes don't exist, but similar objects do? How would we tell the difference?
