A panel of independent experts reported this week that NASA lacks funding to maintain most of its decades-old facilities, could lose its engineering prowess to the commercial space industry, and has a shortsighted roadmap for technology development.

"NASA’s problem is it always seems to have $3 billion more program than it has of funds," said Norm Augustine, chair of the National Academies panel chartered to examine the critical facilities, workforce, and technology needed to achieve NASA's long-term strategic goals and objectives. Augustine said a similar statement could sum up two previous high-level reviews of NASA's space programs that he chaired in 1990 and 2009. But the report released Tuesday put NASA's predicament in stark terms.

Grumbling about crumbling infrastructure

Around 83 percent of NASA's facilities are beyond their design lifetimes , and the agency has a $3.3 billion backlog in maintenance. When you consider NASA's $250 million estimate for normal year-to-year maintenance, it would take a $600 million uptick in NASA's annual budget for infrastructure repairs to catch up on the backlog within the next 10 years.

Google is under investigation by Europe’s privacy watchdog over its processing of personal data in the development of one of its artificial intelligence models, as regulators ramp up their scrutiny of Big Tech’s AI ambitions.

Ireland’s Data Protection Commission, which is responsible for enforcing the EU’s General Data Protection Regulation, said it had launched a statutory inquiry into the tech giant’s Pathways Language Model 2, or PaLM 2.

PaLM 2 was launched in May 2023 and predates Google’s latest Gemini models, which power its AI products. Gemini, which was launched in December of the same year, is now the core model behind its text and image-generation offering.

Two of the world's largest automakers are becoming closer friends, we learned this morning. Hyundai Motor Group and General Motors, which together sold 13.5 million cars last year, have decided to try and collaborate in a range of areas in the coming years, including vehicle design, technology development, and even supply chain sourcing.

GM is one of the world's oldest and most established automakers and has a long legacy of clever engineering solutions, albeit one often hamstrung by corporate decision-making.

Meanwhile, GM was just a year from its 60th birthday when HMG got going, and while the Korean automaker was not taken particularly seriously in the US as a budget brand at launch, over the last 15 years its products have been class-leading, especially its electric vehicles.

Not being able to solder puts a hard cap on the kinds of devices you can fix at home. As more modern devices add in circuit boards and discrete electronics (needed or otherwise), soldering is often the only way to save an otherwise functional object from ending up in a junk drawer, or landfill.

That's the kind of roadblock iFixit's FixHub is intended to address. The repair store and repairability advocate now offers battery-powered soldering tools and beginner's kits, intended to make soldering something you can do almost anywhere, quickly, with a few features intended to help out novices and those feeling a bit rusty.

iFixit, which says it is going "all-in on soldering" in a press release, offers a few interconnected pieces as part of a FixHub system:

When it comes to working out, I'm a data nerd. A Google spreadsheet contains every bike ride I've been on for the past four years, tracking data points ranging from average moving speed to normalized power output. Sometimes I ride just for fun—road cycling is one of my favorite activities, period—so I'm not always thinking about cadence and power curves when I'm on the bike. Fitness-focused rides, on the other hand, mean a lot of looking away from the road and down at my bike computer. That's comfortable for me most of the time, but sometimes the cars are flying by or frost heaves are coming fast and furious, so the smart move is keeping my eyes down the road. So I was intrigued when I had a chance to check out ActiveLook's Engo 2 augmented reality sunglasses with a built-in head-up display.

Priced at $299 (or $349 for photochromic lenses), the Engo 2 essentially takes data from your Garmin bike computer, watch, or fitness tracker; Apple Watch; Android Wear device, Suunto watch, or ActiveLook's homegrown app and projects it toward the top inside part of the right lens. (Garmin is the only bike computer supported by ActiveLook.)

From most angles, the Engo 2 looks like a normal pair of sports-oriented sunglasses, with wide, curved, and extensive lenses. The only oddity is a small metal plate in the middle of the glasses, right over the bridge of the nose, which is a sensor. Swipe from left to right, and the display will switch to another view or shut off—if your finger isn't too sweaty or your swipe is insufficiently forceful.

The Polaris Dawn mission took firm step into the future on Thursday morning when two private citizens, Jared Isaacman and Sarah Gillis, briefly ventured outside their Dragon spacecraft.

Although each only spent about eight minutes outside the capsule, the spacewalk was unquestionably a major success for SpaceX and the four astronauts flying in orbit. This marked the first time that a private company, SpaceX, conducted a spacewalk. Funded by Isaacman, the mission spurred a frenetic two-year period of spacesuit development, testing, and simulations by the California company to reach Thursday's remarkably smooth operations.

Isaacman emerged from Dragon at 6:52 am ET (10:52 UTC) as the spacecraft passed near Australia on the planet below. A billionaire, entrepreneur, and avid pilot, Isaacman paused for just a moment as he stood on the edge of eternity and looked back at planet Earth.

Growing up, if I wanted to experiment with something technical, my dad made it happen. We shared dozens of tech adventures together, but those adventures were cut short when he died of cancer in 2013. Thanks to a new AI image generator, it turns out that my dad and I still have one more adventure to go.

Recently, an anonymous AI hobbyist discovered that an image synthesis model called Flux can reproduce someone's handwriting very accurately if specially trained to do so. I decided to experiment with the technique using written journals my dad left behind. The results astounded me and raised deep questions about ethics, the authenticity of media artifacts, and the personal meaning behind handwriting itself.

Beyond that, I'm also happy that I get to see my dad's handwriting again. Captured by a neural network, part of him will live on in a dynamic way that was impossible a decade ago. It's been a while since he died, and I am no longer grieving. From my perspective, this is a celebration of something great about my dad—reviving the distinct way he wrote and what that conveys about who he was.

Microsoft has updated a key cryptographic library with two new encryption algorithms designed to withstand attacks from quantum computers.

The updates were made last week to SymCrypt , a core cryptographic code library for handing cryptographic functions in Windows and Linux. The library, started in 2006, provides operations and algorithms developers can use to safely implement secure encryption, decryption, signing, verification, hashing, and key exchange in the apps they create. The library supports federal certification requirements for cryptographic modules used in some governmental environments.

Massive overhaul underway

Despite the name, SymCrypt supports both symmetric and asymmetric algorithms. It’s the main cryptographic library Microsoft uses in products and services including Azure, Microsoft 365, all supported versions of Windows, Azure Stack HCI, and Azure Linux. The library provides cryptographic security used in email security, cloud storage, web browsing, remote access, and device management. Microsoft documented the update in a post on Monday.

You might sideload an Android app, or manually install its APK package, if you're using a custom version of Android that doesn't include Google's Play Store. Alternately, the app might be experimental, under development, or perhaps no longer maintained and offered by its developer. Until now, the existence of sideload-ready APKs on the web was something that seemed to be tolerated, if warned against, by Google.

This quiet standstill is being shaken up by a new feature in Google's Play Integrity API. As reported by Android Authority , developer tools to push "remediation" dialogs during sideloading debuted at Google's I/O conference in May, have begun showing up on users' phones. Sideloaders of apps from the British shop Tesco , fandom app BeyBlade X , and ChatGPT have reported "Get this app from Play" prompts, which cannot be worked around. An Android gaming handheld user encountered a similarly worded prompt from Diablo Immortal on their device three months ago.

Google's Play Integrity API is how apps have previously blocked access when loaded onto phones that are in some way modified from a stock OS with all Google Play integrations intact. Recently, a popular two-factor authentication app blocked access on rooted phones , including the security-minded GrapheneOS. Apps can call the Play Integrity API and get back an "integrity verdict," relaying if the phone has a "trustworthy" software environment, has Google Play Protect enabled, and passes other software checks.
