    Can you explain how that works? With the row-per-item I can see how you’d use locking primitives etc easily to deal with multiple concurrent shopping carts claiming available inven…

    Right, except the researchers are the ones that added the button, pressed it and now are upset at Ford, in your example. GitHub agents don’t have access to unrelated private repos …

    How is this a Github vulnerability? The researchers are the ones that grant the agent access to private repos and then ask it to answer questions in public repos.. of course this a…

    There are attacks that allow dumping RAM if the device is powered on though and you have physical access. Depending on config it may be very easy (just plug in a dumper over Thunde…

    I’ve had very good success in similar setups where you have some sort of “oracle” and can generate enormous corpuses of test data, such that you really, really trust the LLM code m…

    The point of “durable” implying stored to durable media is precisely that it allows the operator of the system to make that kind of calculation. They know the disks they picked and…

    Comment #48076142

    I used to say this as well but like.. industry has, for a long time now equated “durable” with “stored on disk”. Any DBA will assume that’s what it means, and use that fact when th…

    If a company says “encrypted at rest” that is generally compliance-speak for “not encrypted, but the hard drive partition is encrypted”. Various certifications require this, I gues…

    The complexity for that is almost always for redundancy and for ease of deploys.

    I feel like I’ve seen elsewhere that the argument there is that you often must have this optimisation working in algos that rely on it or you will get stack overflows. Having a key…

    Utility solar is cheaper in studies that do not factor in the cost of distribution, but the picture is much less clear when total system cost is considered - not having to pay for …

    No reason to be rude or hyperbolic - I agree with you that cars destroy communities and we should strive to reduce the need for cars and parking. For solar powered homes specifical…

    Respectfully, 30kWh is not much in this context. In 10 years every modern 2-car home will have 200kWh on the driveway just from the EVs; add a 100kWh whole home battery at a price …

    Fooled by Randomness talks a good bit about this, and argues it’s true - except you don’t know what to bet on. Hence the outlier successes will be from extreme risk takers, and for…

    This was really good, and second leaning on property testing. I’ve had really good outcomes from setting up Schemathesis and getting blanket coverage for stuff like “there should b…

    They are clearly suggesting that the story recurring every two months is Astro-turfed, not that the story itself is false?

    I mean, no, it's more than that. You also need to choose optimal instruction encoding, and you need to understand how relocs work - which things can you resolve now vs which requir…

    I am surprised by the number of comments that say the assembler is trivial - it is admittedly perhaps simpler than some other parts of the compiler chain, but it’s not trivial. Wha…

    I don’t understand this summary - isn’t this a summary of the authors recitation of Masleys position? It’s missing the part that actually matters, the authors position and how it d…

    lol no, but if you are in a regular vehicle, you can see under the front of the bus as you pass it, it’s a standard safety practice? The first picture of the bus in this random art…

    Aye, and to always look for feet under and by the front wheel of vehicles like that. Stopped buses similarly, people get off the bus, whip around the front of them and straight int…
