Submission + - Moon-bound asteroid could cripple Earth's satellites, say astronomers (substack.com) 1

Submitted by KentuckyFC
KentuckyFC writes: In DEcember last year, NASA's Asteroid Terrestrial-impact Last Alert System (ATLAS) picked up an 60-meter asteroid that appeared to be heading our way. Further observations quickly ruled out the possibility of a collision but in April, the agency announced that 2024 YR4 had a 4 per cent chance of hitting the moon instead. Now astronomers have calculated the likely consequences and say the impact would create a crater 1 km across and send 100 millions tonnes of ejecta hurtling into space and towards us. The risks to astronauts and satellite systems are clearly existential. The team say this kind of risk is not considered in planetary defence plans, which now urgently need to be updated.

Submission + - Another large Black hole in "our" Galaxy (arxiv.org)

Submitted by RockDoctor
RockDoctor writes: A recent paper on ArXiv reports a novel idea about the central regions of "our" galaxy.

Remember the hoopla a few years ago about radio-astronomical observations producing an "image" of our central black hole — or rather, an image of the accretion disc around the black hole — long designated by astronomers as "Sagittarius A*" (or SGR-A*)? If you remember the image published then, one thing should be striking — it's not very symmetrical. If you think about viewing a spinning object, then you'd expect to see something with a "mirror" symmetry plane where we would see the rotation axis (if someone had marked it). If anything, that published image has three bright spots on a fainter ring. And the spots are not even approximately the same brightness.

This paper suggests that the image we see is the result of the light (radio waves) from SGR-A* being "lensed" by another black hole, near (but not quite on) the line of sight between SGR-A* and us. By various modelling approaches, they then refine this idea to a "best-fit" of a black hole with mass around 1000 times the Sun, orbiting between the distance of the closest-observed star to SGR-A* ("S2" — most imaginative name, ever!), and around 10 times that distance. That's far enough to make a strong interaction with "S2" unlikely within the lifetime of S2 before it's accretion onto SGR-A*.)

The region around SGR-A* is crowded. Within 25 parsecs (~80 light years, the distance to Regulus [in the constellation Leo] or Merak [in the Great Bear]) there is around 4 times more mass in several millions of "normal" stars than in the SGR-A* black hole. Finding a large (not "super massive") black hole in such a concentration of matter shouldn't surprise anyone.

This proposed black hole is larger than anything which has been detected by gravitational waves (yet) ; but not immensely larger — only a factor of 15 or so. (The authors also anticipate the "what about these big black holes spiralling together?" question : quote "and the amplitude of gravitational waves generated by the binary black holes is negligible.")

Being so close to SGR-A*, the proposed black hole is likely to be moving rapidly across our line of sight. At the distance of "S2" it's orbital period would be around 26 years (but the "new" black hole is probably further out than than that). Which might be an explanation for some of the variability and "flickering" reported for SGR-A* ever since it's discovery.

As always, more observations are needed. Which, for SGR-A* are frequently being taken, so improving (or ruling out) this explanation should happen fairly quickly. But it's a very interesting, and fun, idea.

University of Michigan Study Advocates Ban of Facial Recognition in Schools (venturebeat.com) 18

Posted by msmash from the moving-forward dept.
University of Michigan researchers recently published a study showing facial recognition technology in schools has limited efficacy and presents a number of serious problems. From a report: The research was led by Shobita Parthasarathy, director of the university's Science, Technology, and Public Policy (STPP) program, and finds the technology isn't just ill-suited to security purposes, it can actively promote racial discrimination, normalize surveillance, and erode privacy while marginalizing gender nonconforming students. The study follows the New York legislature's passage of a moratorium on the use of facial recognition and other forms of biometric identification in schools until 2022. The bill, a response to the Lockport City School District launching a facial recognition system, was among the first in the nation to explicitly regulate or ban use of the technology in schools. That development came after companies including Amazon, IBM, and Microsoft halted or ended the sale of facial recognition products in response to the first wave of Black Lives Matter protests in the U.S.

Early this evening, the Council of Elders announced a planetary day of mourning and magnanimity.

K'Nord, Speaker for the Council, spoke thusly:

"Citizens and Podmates, the Council is pleased to announce that after seven and a half full years -- the longest campaign in the history of the Martian Defense Force -- the diabolical mechanized adversary from the blue world has been defeated. Our defense forces, counted in the billions, have finally surrounded and denied the invader the light and warmth it needs to survive. The blueworlders have acknowledged defeat and ceased contact. Ths invasion, at least on this front, is now over.

Let us raise our glasses to mourn the lost gelsacs of at least half our press corps, some of whose entire careers have been dedicated to coverage of this conflict -- and in a spirit of magnanimity in victory, we -- the victors of the Conflict at Endeavour Crater -- must also raise our glasses in awe and respect of our longest-lived and most challenging foe."

Shortly thereafter, a wizened old retired Councilmember, his gelsacs having long ago been ceremonially ground into a fine tartare and shared amongst the Council, wiped a perchlorate tear from his eye: "Well-done, blueworlders. Well-done."

Submission + - Bell Canada wants pirate websites blocked for Canadians 1

wierzpio writes: According to Rob Malcolmson, Bell Canada's VP of regulatory affairs, Canada is a safe haven to internet pirates and the only solution is to create federally mandated blocklist of pirate websites. Unlike existing blocklist in the U.K., Bell's plan appears to involve no judicial oversight. "'Engaging in extrajudicial attempts to block access to sites, I think, raises all kinds of Charter of Rights and Freedoms issues,' argues Michael Geist, a University of Ottawa professor and internet law expert."

My Dad's TRS-80 Model III was the first I can recall using. I was about 3, and I like to press the clicky red reset button on it. I think he didn't enjoy that, as he was probably working on something at the time. A kid can be worse than a cat when it comes to computer interference.
The first I owned, as a gift, was a Color Computer II, with the game cartridges like Doubleback, and Megamunchers. Didn't do much computing on it. Then we got a Commodore 64 and Vic 20 parts. Never got the Vic 20 going, but we had fun with the Commodore 64. The school, where my Dad was a teacher had his Model III, and a Model IV, and a bunch of Apple ][, and ][e computers. Soon there was an 8088 as well.

Submission + - Investigation Finds Inmates Built Computers, Hid Them In Prison Ceiling (cbs6albany.com)

Submitted by Anonymous Coward
An anonymous reader writes: The discovery of two working computers hidden in a ceiling at the Marion Correctional Institution prompted an investigation by the state into how inmates got access. In late July, 2015 staff at the prison discovered the computers hidden on a plywood board in the ceiling above a training room closet. The computers were also connected to the Ohio Department of Rehabilitation and Correction's network. Authorities say they were first tipped off to a possible problem in July, when their computer network support team got an alert that a computer "exceeded a daily internet usage threshold." When they checked the login being used, they discovered an employee's credentials were being used on days he wasn't scheduled to work. That's when they tracked down where the connection was coming from and alerted Marion Correctional Institution of a possible problem. Investigators say there was lax supervision at the prison, which gave inmates the ability to build computers from parts, get them through security checks, and hide them in the ceiling. The inmates were also able to run cabling, connecting the computers to the prison's network.

Submission + - Google Ruins the Assistant's Shopping List, Turns It Into a Google Express Ad (arstechnica.com)

Submitted by Anonymous Coward
An anonymous reader writes: The Google Assistant, Google's voice assistant that powers the Google app on Android phones, tablets, and Google Home, has just gotten a major downgrade. In a move reminiscent of all the forced and user-hostile Google+ integrations, Google has gutted the Google Assistant's shopping list functionality in order to turn it into a big advertisement for Google's shopping site, Google Express. The shopping list has been a major feature of the Google Assistant. You can say "Add milk to my shopping list," and the Google Assistant would dutifully store this information somewhere. The shopping list used to live in Google Keep. Keep is Google's primary note-taking app, making it a natural home for the shopping list with lots of useful tools and management options. Now the shopping list lives in Google Express. Express is an online shopping site, and it has no business becoming a dedicated place to store a shopping list that probably has nothing to do with Google's online marketplace. Since Google Express is an online shopping site (and, again, has no business having a note-taking app grafted onto it), the move from Keep to Google Express means the Assistant's shopping list functionality loses the following features: Being able to reorder items with drag and drop.
Reminders; Adding images to the shopping list; Adding voice recordings to the shopping list; Real time collaboration with other users (Express has sharing, but you can't see other people as they type—you have to refresh.); Android Wear integration; Desktop keyboard shortcuts; Checkbox management: deleting all checked items, unchecking all items, hiding checkboxes. Alternatively, the move from Keep to Google Express means the Assistant shopping list gains the following features: Google Express advertising next to every list item; Google Express advertising at the bottom of the page.

Submission + - SPAM: Exploit Revealed For Remote Root Access Vulnerability Affecting Many Routers

Submitted by Orome1
Orome1 writes: Back in January 2013, researchers from application security services firm DefenseCode unearthed a remote root access vulnerability in the default installation of some Cisco Linksys (now Belkin) routers. The flaw was actually found in Broadcom’s UPnP implementation used in popular routers, and ultimately the researchers extended the list of vulnerable routers to encompass devices manufactured by the likes of ASUS, D-Link, Zyxel, US Robotics, TP-Link, Netgear, and others. Since there were millions of vulnerable devices out there, the researchers refrained from publishing the exploit they created for the flaw, but now, four years later, they’ve released their full research again, and this time they’ve also revealed the exploit.
