New Rowhammer attacks give complete control of machines running Nvidia GPUs
15 hours ago
- High-performance GPUs costing $8,000+ are often shared in cloud environments, making them targets for attacks.
- Two new attacks exploit Rowhammer techniques on Nvidia GPUs, allowing malicious users to gain full root control of host machines by inducing bit flips in DRAM memory.
- Rowhammer attacks involve repeated access to memory, causing electrical disturbances that flip bits from 0 to 1 or vice versa, initially demonstrated on DDR3 DRAM in 2014-2015.
- Over the past decade, Rowhammer has evolved to target DDR3 with ECC, DDR4 with protections like TRR, use advanced techniques like RowPress, and even work over networks or root Android devices.
- Last year, Rowhammer was first shown to work on GDDR DRAM in Nvidia GPUs, achieving modest results with only eight bit flips, primarily degrading neural network output.
- The article notes it does not cover HBM memory, which uses extra stacks and parity for ECC, similar to having an extra DRAM chip, and HBM controllers manage complex capacities by disabling only faulty dies instead of entire stacks.

The open web isn't dying, we're killing it
8 hours ago
- Anil Dash's article highlights threats to the open web from large companies exploiting open systems.
- The enclosure of the web predates AI, driven by winner-takes-all dynamics, convenience, and monopoly power.
- Users contributed to the decline by choosing platforms for convenience, rebuilding social graphs in private databases, and promoting closed spaces.
- Convenience from platforms accelerated centralization, making openness seem less valuable than ease of use.
- The open web's sustainability was undermined by reliance on advertising, which reshaped systems around advertisers' needs.
- Neglect by users and organizations, such as not supporting open tools economically, played a role in the web's decline.
- Building a better web requires accepting trade-offs like less convenience, paying for services, and prioritizing user agency.
- The open web needs active participants—maintainers, contributors, and donors—to thrive, moving beyond a consumer mindset.
The machines are fine. I'm worried about us
13 hours ago
- The author describes two PhD students, Alice and Bob, who completed similar astrophysics projects. Alice engaged deeply, building understanding through effort, while Bob used an AI agent throughout, producing a paper without the underlying learning.
- Institutions often fail to distinguish between Alice and Bob because quantitative metrics (e.g., paper counts) treat them equally, even though only Alice developed scientific intuition and independent thinking.
- AI tools risk turning researchers into 'competent prompt engineers' who can produce results but lack the deep understanding needed for scientific creativity and problem detection.
- Current AI models can generate publishable work under expert supervision, but the supervision itself—the human expertise—remains essential. Without it, errors go unnoticed.
- The danger is a slow drift toward not understanding the work, where researchers rely on AI for thinking, leading to a loss of the human element that makes science meaningful.
- Using AI as a tool for efficiency (e.g., syntax help) is acceptable, but outsourcing cognitive work undermines the learning process necessary for scientific development.
- Career incentives in academia pressure students to prioritize short-term output over long-term understanding, encouraging reliance on AI, which may harm future scientific capability.
- The author argues that the 'grunt work' of science is where real learning happens, and bypassing it with AI diminishes researchers, even if output appears successful.

- Building a better web requires accepting trade-offs like less convenience, paying for services, and prioritizing user agency.
- The open web needs active participants—maintainers, contributors, and donors—to thrive, moving beyond a consumer mindset.

- The author describes two PhD students, Alice and Bob, who completed similar astrophysics projects. Alice engaged deeply, building understanding through effort, while Bob used an AI agent throughout, producing a paper without the underlying learning.
- Institutions often fail to distinguish between Alice and Bob because quantitative metrics (e.g., paper counts) treat them equally, even though only Alice developed scientific intuition and independent thinking.
- AI tools risk turning researchers into 'competent prompt engineers' who can produce results but lack the deep understanding needed for scientific creativity and problem detection.
- Current AI models can generate publishable work under expert supervision, but the supervision itself—the human expertise—remains essential. Without it, errors go unnoticed.
- The danger is a slow drift toward not understanding the work, where researchers rely on AI for thinking, leading to a loss of the human element that makes science meaningful.
- Using AI as a tool for efficiency (e.g., syntax help) is acceptable, but outsourcing cognitive work undermines the learning process necessary for scientific development.
- Career incentives in academia pressure students to prioritize short-term output over long-term understanding, encouraging reliance on AI, which may harm future scientific capability.
- The author argues that the 'grunt work' of science is where real learning happens, and bypassing it with AI diminishes researchers, even if output appears successful.

- Minimal BASIC is a minimalist version of BASIC with commands for printing, input, assignment, and conditional jumps.
- Programs can be represented as a single string without whitespace; tools like mbStr.py and mbFormat.py convert between formatted and string representations.
- The BNF for Minimal BASIC defines a simple syntax for programs, statements, expressions, variables, labels, and integers.
- Minimal BASIC can serve as a target for compilers; tbc.py translates higher-level tb language features like if-then-else and loops into Minimal BASIC.
- Extensions to Minimal BASIC include more complex expressions with precedence and brackets, and potential support for GOSUB/RETURN, with exprCompiler.py as a starting point.
