  1. Exactly why you shouldn't trust locked firmware. on Five Eyes Intelligence Alliance Argues 'Privacy is Not Absolute' in Push For Encryption Backdoors (itnews.com.au) · · Score: 4, Insightful

    If your phone/computer OEM can force you to use only specified firmware, the spooks can force them to modify the firmware in ways that betray the user.

    Define soon. To seriously break the ECC that bitcoin relies on to protect private keys you need 1500 quantum bits, and the highest entanglement recorded is 20, and the highest # working as a computer is 5. https://arxiv.org/pdf/quant-ph...

    However it may be the case that there's a fundamental limit to the number of qubits that can be entangled at once. Also traditional online banking and wire transfers would be screwed as well.

    Here's a fairly balanced and more nuanced article. https://www.forbes.com/sites/a...

    And it's just not one study, but several from multiple sources showing similar effects.

    And the whole market isn't fungible, one college degree is not interchangeable with another, and the same for students. You're working with a lot on information other than just price and SAT/GPA. Also colleges want the degree to mean something other than "my parents could afford to pay X".

    And while the classroom environment works well for some types of labor training, for other it's only value is as a signal that you intelligence + work ethic is above some minimal level. Our obsession with the college degree obscures the fact most vocations are best learned on the job or in a specialized non-classroom environment.

    There are actually quite a few skilled labor areas that are starting down shortages in the coming decade because the standard default advice to intelligent students was to go to college.

    If college loans were not federally guaranteed, while it would be harder for those from poor backgrounds to graduate, colleges would try to maximize potential lifetime earnings of students and retention rates. Lets be honest about the tradeoffs and costs, rather than go full bernie bro.

    L4, QNX are probably the top 2. And performance is tied to old hardware limitations and models, which make context switches expensive. A cpu better suited to micro-kernels, like the Mill could bring about a different story. If a context switch cost 5-10 cycles instead of hundreds, all of a sudden the micro-kernel architecture looks a lot better.

    It should work for any on-disk filesystem, it's implemented on the kernel/ c-library level. NFS, procfs, debugfs.,tempfs.. are special cases that can either be modified by other systems/kernels, or be modified by calls within the kernel itself. Perhaps dropbox is doing funny things directly to the block layer, but it shouldn't be able to do that without root permisions or setgid somewhere, and that's sketchy for all sorts of reasons.

    If you don't have dropbox deamon running in the background, It's hard to tell if was a rename, or a delete+ new file with the same data, but different metadata. If it is, you use inofity to keep be able to tell which of the two occurred. You may also be able to store the inode and checksum somewhere as a hint.

  22. Once again someone misunderstands hardware. on Bitcoin Mining Now Accounts For Almost One Percent of the World's Energy Consumption (theoutline.com) · · Score: 1

    In a given pace of hardware, performance does not scale linearly with electricity consumed. Higher clocks consume progressively more energy. So a producer will pick a clock such that the performance boost of the last bump exactly matched the marginal increase of electric consumption. However a sustainable operation needs an average marginal cost far below that to pay for fixed and capital costs.

    And this also ignore difference proof systems a crypto can use.

    State's already routinely pull Driver's Licenses for non-driving offense.
