MIT Rocket Team Recovers Data from Crashed Rocket

2024-12-18

In Spring 2020, the MIT Rocket team launched rockets at the FAR site in the Mojave desert. A second-stage rocket crashed without deploying its parachutes, burying itself 3 meters underground. Despite significant damage to the avionics, the team successfully recovered data from a damaged flash chip. Using a salt solution to create temporary electrical contact, they were able to read the flash memory and determine the cause of the crash.

“Bread and Circuses”: Reframing the Narrative of Roman Decline

“Bread and Circuses”: Reframing the Narrative of Roman Decline

This article delves into the origins and meaning of the proverb “bread and circuses.” Tracing it back to Juvenal's satire, the author argues it's not a positive assessment of the Roman populace but a critique of their abdication of political responsibility in favor of basic needs and entertainment. The author challenges the common notion that “bread and circuses” caused Rome's downfall, attributing the decline to prolonged civil wars and instability, with the populace prioritizing peace above all else. Ultimately, the article reveals the true meaning of “bread and circuses”: a lament for the loss of political liberty and the constrained dreams of the Roman people.

New Study Pinpoints Neanderthal Interbreeding with Modern Humans

New Study Pinpoints Neanderthal Interbreeding with Modern Humans

A new analysis of ancient DNA from modern humans in Europe and Asia has precisely determined the timeframe of Neanderthal interbreeding with Homo sapiens. The interbreeding began approximately 50,500 years ago and lasted for about 7,000 years, until Neanderthals began to disappear. This research, using 58 ancient genomes and present-day human genomes, revealed an average interbreeding date of around 47,000 years ago, consistent with archeological evidence. The study also found that East Asians possess about 20% more Neanderthal genes than Europeans and West Asians, potentially due to the presence of mixed genes when modern humans migrated eastward around 47,000 years ago. The findings offer a more complete picture of past human migrations and gene flow, and shed light on the impact of Neanderthal genes on modern human health.

California Orders Uber to Fingerprint Drivers for Teen Rides

California Orders Uber to Fingerprint Drivers for Teen Rides

The California Public Utilities Commission (CPUC) ruled that Uber must fingerprint drivers for its teen ride-hailing service, Uber for Teens, to continue operating in the state. This decision stems from safety concerns regarding unaccompanied minors. While Uber has historically resisted fingerprint-based background checks, the CPUC cited the importance of protecting children from potential sexual offenders. The ruling significantly impacts Uber's operations, while competitor HopSkipDrive, which already employs stricter safety measures including fingerprinting, supports the decision. The added cost of fingerprinting may lead to higher prices for Uber's teen ride service.

Multiple Vulnerabilities in Qualcomm DSP Driver Raise Security Concerns

2024-12-16

Google's Project Zero team discovered six vulnerabilities in a Qualcomm DSP driver, one of which was exploited in the wild. Analysis of kernel panic logs provided by Amnesty International, without access to the exploit sample itself, revealed the flaws. A code review uncovered multiple memory corruption vulnerabilities, including use-after-free and refcount leaks. The attacker likely leveraged these vulnerabilities with inotify_event_info object heap spraying to achieve code execution. This highlights the critical need for improved security in Android's third-party drivers.

Crystal Ball Challenge: Knowing the Future Isn't Enough to Guarantee Riches

Elm Partners conducted an experiment called the "Crystal Ball Challenge," where 118 finance students traded stocks and bonds using the Wall Street Journal's front page from one day in the future (with price data blacked out) over 15 days. The results were surprising: despite having future information, most participants didn't profit, averaging a mere 3.2% gain. Experienced traders, however, performed exceptionally well, averaging a 130% gain. The experiment demonstrated that even with 'future' knowledge, successful investing requires sensible position sizing. This research highlights the importance of decision-making under uncertainty and position sizing, offering valuable lessons for financial education.

UK's Illegal Cybertruck Faces Uphill Battle for Legalization

Yianni Charalambous, a UK car customizer, is attempting to register a Tesla Cybertruck for road use in the UK, following a similar success in the Czech Republic. However, the Cybertruck's sharp design clashes with UK and EU pedestrian safety regulations, posing significant challenges. Its unique steer-by-wire system, reliance on OTA updates unavailable in the UK, and incompatibility with EU recall systems further complicate matters. Experts deem its chances of passing the UK's IVA test extremely slim.

Breakthrough in Reachability Analysis of the Domain Name System

Researchers have presented the first decision procedure for verifying the Domain Name System (DNS), establishing its complexity as 2ExpTime. The study formalizes DNS semantics and uses a novel abstraction based on positive prefix-testable languages, reducing the DNS verification problem to the verification problem for pushdown systems. This approach effectively models attack vectors in DNS, such as amplification attacks and rewrite blackholing, providing a new theoretical foundation for ensuring DNS security and reliability.

OpenAI's new language model, o3, achieved a 25% accuracy rate on the FrontierMath dataset, sparking a debate within the mathematics community about AI's mathematical capabilities. FrontierMath is a secret dataset containing hundreds of complex mathematical problems that require calculating specific numerical values rather than simply proving theorems. o3's performance is surprising, as it surpasses the previous limitations of AI, which could only solve problems at the level of math olympiads or undergraduate studies. While the dataset's difficulty and sample representativeness remain debated, this achievement marks significant progress for AI in mathematics, prompting reflections on AI's future development and the direction of mathematical research.

UK Electricity Bills Soar: High Subsidies and Grid Investment Lag

High UK electricity bills aren't solely due to wholesale power costs. A recent analysis reveals that network costs and green energy subsidies are major drivers. Twenty years of stagnant grid investment now necessitate urgent expansion, skyrocketing network costs. Contracts subsidizing renewables will continue increasing bills, while past subsidies, like the Renewables Obligation and Feed-in Tariff, failed to adjust quickly enough to falling renewable energy prices, locking in massive long-term costs. The author suggests reducing grid dependence or improving grid utilization as pathways to lower future electricity bills.

Trey, a programmer working for a 3G telecom startup, wrote an automated payment testing program intended for small test transactions. Three bugs in the code, however, caused the program to credit his test account with $100 every five minutes. A lack of liveness check meant that when one gateway failed, the program continued running for hours, accumulating a substantial sum. The next morning, Trey faced questioning from the security team until his department head explained the situation, but the test account balance was reset to zero.
