OK, sit down, everyone — we don’t want you falling over and hurting yourself when you learn the news that actually yes, your phone has been listening to your conversations all along. Shocking, we know, but that certainly seems to be what an outfit called Cox Media Group (CMG) does with its “Active Listening” software, according to a leaked slide deck that was used to pitch potential investors. The gist is that the software uses a smartphone’s microphone to listen to conversations and pick out keywords that it feeds to its partners, namely Google, Facebook, and Amazon so that they can target you with directed advertisements. Ever have an IRL conversation about something totally random only to start seeing references to that subject pop up where they never did before? We sure have, and while “relationship mining” seemed like a more parsimonious explanation back in 2017, the state of tech makes eavesdropping far more plausible today. Then there’s the whole thing of basically being caught red-handed. The Big Three all huffed and puffed about how they were shocked, SHOCKED to learn that this was going on, with reactions ranging from outright denial of ever partnering with CMG to quietly severing their relationship with the company. So much for years of gaslighting on this.

Why is it always a helium leak? It seems whenever there’s a scrubbed launch or a narrowly averted disaster, space exploration just can’t get past the problems of helium plumbing. We’ve had a bunch of helium problems lately, most famously with the leaks in Starliner’s thruster system that have prevented astronauts Butch Wilmore and Suni Williams from returning to Earth in the spacecraft, leaving them on an extended mission to the ISS. Ironically, the launch itself was troubled by a helium leak before the rocket ever left the ground. More recently, the Polaris Dawn mission, which is supposed to feature the first spacewalk by a private crew, was scrubbed by SpaceX due to a helium leak on the launch tower. And to round out the helium woes, we now have news that the Peregrine mission, which was supposed to carry the first commercial lander to the lunar surface but instead ended up burning up in the atmosphere and crashing into the Pacific, failed due to — you guessed it — a helium leak.

The Sun has been remarkably active lately, so much so that it might have set a new sunspot record. According to the sun watchers at the Space Weather Prediction Center, on August 8, the Solar Dynamics Observatory snapped a picture that was positively bedazzled with sunspots. Counting methods vary, but one count put the sunspot number at a whopping 337 that day. That would be the largest number since 2001, during the peak of Solar Cycle 23. The sunspot number is highly correlated with solar storms and coronal mass ejections; more spots mean more magnetic activity and more chance for something to go very, very wrong. We’ve been pretty lucky so far with Solar Cycle 25; despite being much more active than the relatively lazy Cycle 24 and much stronger than predicted, most of this cycle’s outbursts have been directed away from Earth or only dealt us a glancing blow. Seeing all those spots, though, makes us think it’s only a matter of time before we get hit with something that does more than make pretty lights.

They’re back! The San Francisco autonomous vehicle hijinks, that is, as Waymo’s fleet of driverless cars recently took up the fun new hobby of honking their horns in the wee hours of the morning. Meat-based neighbors of a Waymo parking lot in the South Market neighborhood took offense at the fleet of autonomous vehicles sounding off at 4:00 AM as they shuffled themselves around in the parking lot in a slow-motion ballet of undetermined purpose. The horn-honking is apparently by design, as the cars are programmed to tootle their horn trumpets melodiously if they detect another vehicle backing up into them. That’s understandable; we’ve tootled ourselves under these conditions, with vigor, even. But when the parking lot is full of cars that (presumably) can’t hear the honking and (also presumably) know where the other driverless vehicles are as well as their intent, what’s the point? Luckily, Waymo is on the case, as they issued a fix to keep the peace. Unfortunately, it sounds like the fix is just to geofence the lot and inhibit honking there, which seems like just a band-aid to us.

“Please say it wasn’t a regex, please say it wasn’t a regex; aww, crap, it was a regex!” That seems to be the conclusion now that Crowdstrike has released a full root-cause analysis of its now-infamous Windows outage that took down 8 million machines with knock-on effects that reverberated through everything from healthcare to airlines. We’ve got to be honest and say that the twelve-page RCA was a little hard to get through, stuffed as it was with enough obfuscatory jargon to turn off even jargon lovers such as us. The gist, though, is that there was a “lack of a specific test for non-wildcard matching criteria,” which pretty much means someone screwed up a regular expression. Outside observers in the developer community have latched onto something more dire, though, as it appears the change that brought down so many machines was never tested on a single machine. That’s a little — OK, a lot — hard to believe, but it seems to be what Crowdstrike is saying. So go ahead and blame the regex, but it sure seems like there were deeper, darker forces at work here.

Good news, bad news for Sun watchers this week, as our star launched a solar flare even bigger than the one back in May that gave us an amazing display of aurora that dipped down into pretty low latitudes. This was a big one; where the earlier outburst was only an X8.9 class, the one on July 23 was X14. That sure sounds powerful, but to put some numbers to it, the lower end of the X-class exceeds 10-4 W/m2 of soft X-rays. Numbers within the class designate a linear increase in power, so X2 is twice as powerful as X1. That means the recent X14 flare was about five times as powerful as the May flare that put on such a nice show for us. Of course, this all pales in comparison to the strongest flare of all time, a 2003 whopper that pegged the needle on satellite sensors at X17 but was later estimated at X45.

What is this dystopia coming to when one of the world’s largest tech companies can’t find a way to sufficiently monetize a nearly endless stream of personal data coming from its army of high-tech privacy-invading robots? To the surprise of almost nobody, Amazon is rolling out a paid tier to their Alexa service in an attempt to backfill the $25 billion hole the smart devices helped dig over the last few years. The business model was supposed to be simple: insinuate an always-on listening device into customers’ lives to make it as easy as possible for them to instantly gratify their need for the widgets and whatsits that Amazon is uniquely poised to deliver, collecting as much metadata along the way as possible; multiple revenue streams — what could go wrong? Apparently a lot, because the only thing people didn’t do with Alexa was order stuff. Now Amazon is reportedly seeking an additional $10 a month for the improved AI version of Alexa, which will be on top of the ever-expanding Amazon Prime membership fee, currently at an eye-watering $139 per year. Whether customers bite or not remains to be seen, but we think there might be a glut of Echo devices on the second-hand market in the near future. We hate to say we told you so, but — ah, who are we kidding? We love to say we told you so.
