Tesla's model 3 is now one of the five top-selling sedans in America (while sales of the Mercedes-Benz C-Class are down 28 percent through September), Bloomberg reports. Elon Musk tweeted out a link to their article on Thursday -- but it was his other tweet, a satirical criticism of the SEC, that made headlines. MarketWatch reports: Tesla shares ended 7% lower on Friday as Wall Street reacted to Musk's tweet seemingly out of nowhere late Thursday about the "Shortseller Enrichment Commission." Musk also tweeted that day that short sellers were "value destroyers" and should be illegal. Friday's losses for Tesla "produced more than half a billion in paper profit for the shorts," S3 Partners LLC, which tracks real-time short interest data, said in a note. Since news of the Musk's settlement with the SEC, shorts are up $941 million, S3 Partners said. "Clearly short positions are building in the wake of strong selling by longs, as Musk demonstrates a refusal to keep away from controversy," the note said. The article notes that last Saturday the SEC settled charges that Musk misled investors with a tweet about taking Tesla private. "Terms of the settlement included requiring Tesla to rein in Musk's social-media communications, but it was unclear when Tesla intends to implement that.... The settlement has yet to be court-approved." On Friday Musk was back on point, tweeting out the news that Tesla owners "can refer someone to buy a Tesla & get any image they want laser etched in glass & sent to deep space for millions of years."

After a bitter battle between Republicans and Democrats, the Senate votes in favour of Kavanaugh.

Senate votes 50-48 to confirm Brett Kavanaugh to the Supreme Court. Here's how each Senator voted.

Poll: How do you feel about Al Franken leaving the Senate?

I have not heard from anyone with an idea of what Kavanaugh meant in his "what goes around comes around" line. What happened in the political system of the early 2000s that "we all know" about? Mystery.

"Linux runs the world, right? So we want to make sure that things are secure," says Linux kernel maintainer Greg Kroah-Hartman. When asked in a new video interview which bug makes them most angry, he first replies "the whole Spectre/Meltdown problem. What made us so mad, in a way, is we were fixing a bug in somebody else's layer!" One also interesting thing about the whole Spectre/Meltdown is the complexity of that black box of a CPU is much much larger than it used to be. Right? Because they're doing -- in order to eke out all the performance and all the new things like that, you have to do extra-special tricks and things like that. And they have been, and sometimes those tricks come back to bite you in the butt. And they have, in this case. So we have to work around that. But a companion article on Linux.com notes that "Intel has changed its approach in light of these events. 'They are reworking on how they approach security bugs and how they work with the community because they know they did it wrong,' Kroah-Hartman said." (And the article adds that "for those who want to build a career in kernel space, security is a good place to get started...") Kroah-Hartman points out in the video interview that "we're doing more and more testing, more and more builds," noting "This infrastructure we have is catching things at an earlier stage -- because it's there -- which is awesome to see." But security issues can persist thanks to outside vendors beyond their control. Linux.com reports: Hardening the kernel is not enough, vendors have to enable the new features and take advantage of them. That's not happening. Kroah-Hartman releases a stable kernel every week, and companies pick one to support for a longer period so that device manufacturers can take advantage of it. However, Kroah-Hartman has observed that, aside from the Google Pixel, most Android phones don't include the additional hardening features, meaning all those phones are vulnerable. "People need to enable this stuff," he said. "I went out and bought all the top of the line phones based on kernel 4.4 to see which one actually updated. I found only one company that updated their kernel," he said. "I'm working through the whole supply chain trying to solve that problem because it's a tough problem. There are many different groups involved -- the SoC manufacturers, the carriers, and so on. The point is that they have to push the kernel that we create out to people." "The good news," according to Linux.com, "is that unlike with consumer electronics, the big vendors like Red Hat and SUSE keep the kernel updated even in the enterprise environment. Modern systems with containers, pods, and virtualization make this even easier. It's effortless to update and reboot with no downtime."

What if Trump's supporters are right about something. Did you ever consider that possibility? What if they were, and you adjusted your view of reality accordingly? Ever consider the possibility that *your* pundits are misleading you, not always theirs?

Bruce Perens co-founded the Open Source Initiative with Eric Raymond -- and he's also Slashdot reader #3872. But this week he wrote in with some news from the world of amateur (or "ham") radio: ARRL has been the USA's representative organization for Amateur Radio for over a century. More recently, the organization has replaced transparency and democratic representation of its membership with confidentiality, policies to stifle dissent, and punishment of their own leadership when they get out of line. A vote happening this month offers members a chance to get back in control. The open letter at that link -- signed by several AARL life members (including Perens), argues that "The members are not currently represented as they should be, due to the continued application of a policy meant for a for-profit corporate board," adding that "The only whistle-blower on the board was publicly castigated for informing us." "The currently-suspended rules that go against the member's interest are temporarily suspended, and could be restored."

AmiMoJo quotes Rock, Paper, Shotgun: Sandbox space sim Limit Theory has been cancelled, six years after a successful crowdfunding campaign on Kickstarter, because main developer Josh Parnell is simply exhausted from working on it for so long. He's spent, he says: emotionally, mentally, physically, and financially. "Not in my darkest nightmares did I expect this day to ever come, but circumstances have reached a point that even my endless optimism can no longer rectify," Parnell said on Friday. He plans to release the source code for folks to poke around but makes clear "it's not a working game." Though Limit Theory blew past its $50,000 goal, drawing $187,865 in pledges (and remember Kickstarter takes a cut), development has gone on years longer than anticipated. Costs have burned through that initial cash and started eating into Parnell's personal savings but, more than that, he's just exhausted.

Long-time Slashdot reader RockDoctor writes: One of the key assumptions of Relativity — both Special and General — is that the speed of light is a constant in all non-accelerating reference frames. As a key assumption, it is also one of the things that gets the kooks, wingnuts and fanatics all riled up, because they have proven that it's wrong, though those pesky scientists refuse to listen to their spittle-flecked presentations. Back in the real world, real scientists also wonder if the assumption is justified, then try to work out how to test it. One idea for performing this test has just been published — that of using the gravitational lensing of distant supernovae to try to interrogate the speed of light in the distant past. When a (relatively) nearby galaxy lenses a (relatively) distant galaxy, it is common for multiple images to be formed. If a supernova occurs in the distant galaxy, then supernova images will be seen in the different images, but typically at different times (on Earth) because the light paths from different images are of different lengths, and were of different lengths in the past. The Chinese-Polish team of authors have studied the possibilities of making such observations and suggest that the LSST (Large Synoptic Survey Telescope, "a wide-field survey reflecting telescope with an 8.4-meter primary mirror, currently under construction, that will photograph the entire available sky every few nights") should detect several thousand gravitationally-lensed distant quasars, and so yield around 50 gravitationally-lensed distant supernovas per year. This is estimated to "produce robust constraints on the speed of light at the level of delta-c/c;= 0.005" (half a percent) in a decade of operations. Which will shut the wingnuts, lunatics and kooks up. Not.At.All.
