Things may not have gone as planned last week for the flying cellphone on Mars, but just because Ingenuity‘s flying career is over doesn’t mean there’s no more work to do. NASA announced this week that it’s going to try a series of “wiggle” maneuvers on Ingenuity‘s rotors, in an attempt to get a better look at the damage to the blade tips and possibly get some clues as to what went wrong. The conjecture at the moment seems to be that a large area of relatively featureless terrain confused the navigation system, which uses down-facing cameras to track terrain features. If the navigation program couldn’t get a bead on exactly how far above the ground it was, it’s possible the copter came in too hard and caused the rotor tips to dig into the regolith. There seems to be some photographic suggestion of that, with what looks like divots in the ground about where you’d expect the rotor tips to dig in, and even scraps of material that look out of place and seem to be about the same color as the rotor blades. All this remains to be seen, of course, and we’re sure that NASA and JPL are poring over all available data to piece together what happened. As much as we hate to say goodbye to Ingenuity, we eagerly await the post-mortem.

From the “No good deed goes unpunished” files, this week came news of a German programmer who probably wishes he had selected better clients. According to Heise Online (English translation), a freelance programmer — referred to only as “defendant” in the article — was retained by a company to look into a database problem in their system. His investigation revealed that the customer’s database was being filled with log messages from a third-party service called Modern Solution GmbH & Co. KG. over a MySQL connection to a remote server. Assuming this connection was dedicated for his client’s use, the programmer looked at the executable used to make the connection with a text editor, which revealed a password in plain text. Upon connecting to the remote database, he found that it not only contained data for all of Modern Solution’s customers, but also data for all the end users of their customers.
Realizing he’d unintentionally wandered into verboten territory, the programmer immediately backed out and contacted Modern Solutions. They quickly fixed the issue, and then just as quickly reported him to the police. Their “investigation” revealed that the programmer had “decompiled” the executable to obtain the password, in violation of German law. The judge agreed, stating that merely looking at and using the password constituted a criminal offense, regardless of intent and despite the fact that Modern Solution had provided the password to the programmer’s client when they sold them the software. The upshot of all of this nonsense? A €3,000 fine for the programmer, if the verdict stands on appeal. It could have been worse, though; German law allows for up to three years in prison for such offenses.

Have you noticed any apps missing from your Android phone lately? We haven’t but then again, we try to keep the number of apps on our phone to a minimum, just because it seems like the prudent thing to do. But apparently, Google is summarily removing apps from the Play Store, often taking the extra step of silently removing the apps from phones. The article, which seems to focus mainly on games, and has a particular bone to pick about the removal of RPG Wayward Souls, isn’t clear about how widespread the deletions are, or what exactly the reason behind the removals could be. But they sure are exercised about it, and rightly so since in some cases the deleted games have actually been paid for by the users, and Google pretty much says that if you think you’re getting a refund, think again. They make some interesting points, such as this being the very definition of larceny, while also acknowledging that in all likelihood Google has a get-out-of-jail-free card buried in some EULA somewhere permitting them to do exactly what they’re doing. Google’s gonna Google, right?

How long does it take a team of rocket scientists to remove two screws? When the screws they’re working on are keeping a priceless sample of asteroid safe, it’s about three months. That’s how long NASA has been working on the OSIRIS-REx sample return canister, which came back to Earth from asteroid Bennu back in September. The container was crammed full of asteroid bits, thanks in part to an overly energetic impact between the sample-collecting boom and Bennu. There was so much stuff that planetary scientists were able to recover about 70 grams of material that was covering the outside of the sealed container; this must have been a boon to the engineers, who got to figure out how to open the jammed cover of the container without anyone breathing down their necks for samples to study. The problem was a pair of stuck fasteners out of the 35 holding the lid on the container; the solution was far more complicated than a spritz of WD-40 and a little bit of heating with an oxy-acetylene torch. Engineers had to design two “clamp-like tools” and test them on a mock-up to make sure they wouldn’t contaminate the sample. We’d love to know more about these tools; trust us, we’ll be looking into this closely. If we find anything, a full article will be forthcoming.

Oh, perfect — now our cars can BSOD. At least that’s how it looks from a forum post showing a Blue Screen of Death on a Ford Mustang Mach E, warning that an over-the-air software update failed, and now the car can’t be driven. The BSOD includes a phone number to reach Ford’s Customer Relationship Center and even presents a wall of text with specific instructions to the wrecker driver for loading the bricked vehicle onto a flatbed. Forum users questioned the photo’s veracity, but there are reports of other drivers getting bricked the same way. And we’ve got to point out that even though this specific bricking happened to an EV, it could just have easily happened to an ICE vehicle too; forum members were particularly prickly about that point. It would be nice if OTA software updates on vehicles could always roll back to the previous driveable state. Still, we suppose that’s not always possible, especially if memory gets corrupted during the update. Maybe the best defense against a bricked vehicle would be to keep a beater around that doesn’t need updates to keep running.

Back near the beginning of the current Solar Cycle 25, we penned an article on what the whole deal is with solar cycles, and what could potentially lie in store for us as the eleven-year cycle of sunspot population developed. Although it doesn’t really come across in the article, we remember being somewhat pessimistic about things, thinking that Solar Cycle 25 would be somewhat of a bust in terms of increased solar activity, given that the new cycle was occurring along with other, longer-period cycles that tend to decrease solar output. Well, looks like we couldn’t have gotten that more wrong if we tried, since the Sun lashed out with a class X solar flare last week that really lit things up. The outburst came from a specific sunspot, number 3514, and clocked in at X2.8, the most powerful flare since just before the end of the previous solar cycle. To put that into perspective, X-class flares have a peak X-ray flux of 10-4 watts/m², which when you think about it is a lot of energy. The flare resulted in a strong radio blackout; pretty much everything below 30 MHz was unusable for a while.

Disappointing news from the US Senate this week as the “AM Radio for Every Vehicle Act” failed to advance in the sausage-making legislative process. We’ve previously covered this bill, which aims to force vehicle manufacturers to provide the means to receive terrestrial AM broadcasts in their cars and trucks without the need for extra subscriptions or charges. The bill’s sponsors tried to get it through on a “unanimous consent” maneuver, but Senator Rand Paul decided he didn’t like the idea of the government mandating what equipment cars should have. The coverage we’ve seen on this bill leads us to believe its sponsors are missing the point. Instead of pitching this as an issue of freedom of choice in entertainment, what they should be concentrating on is the safety aspect of AM radio. We’ve seen how much the government has invested in keeping AM stations on the air in just about any foreseeable emergency, so it’s only natural to look at a car’s AM radio as essential safety equipment like airbags, antilock brakes, and backup cameras. Seems like that’s something that everyone can agree on. Continue reading “Hackaday Links: December 17, 2023”
