    This is Slashdot. I think we can do the math on that one.

    I came for this. I do wonder, though, for how much of the general population does "72.1%" go in one ear and out the other, but "three out of every four" sticks.

    I looked at some of the source code, and the bash commands they execute, and it looks like you have to be on the local (class C) lan in order to attack at least the Linksys beast (the 192.168.blah.blah sure looks like you can't get there from the WAN side), ...

    The javascript running in your browser has access from the LAN side. I have personally compromised my own home router by running Javascript on my public website as a proof of concept.

    Debian/Ubuntu/etc users could easily install the 'redshift' package: http://jonls.dk/redshift/

    ; Global settings
    [redshift]
    temp-day=6400
    temp-night=3900
    location-provider=manual

    ; The location provider and adjustment method settings
    ; are in their own sections.
    [manual]
    lat=51.5
    lon=-0.1

    (Also, I'm disappointed to see "f.lux is patent pending" at the bottom of their page.)

    On Android, I have added a "Night Mode" button. I think this is only possible with Cyanogenmod, and it's an on-off change, rather than the gradual change done with f.lux or redshift.

    Thank you, I did not know that one could create a config file for redshift. I've been starting with a shell script for my day/night parameters. Tell me, is a positive longitude east or west? I assume that positive latitude is north.

  10. Re:Have they studied physics? on "Slingatron" To Hurl Payloads Into Orbit · · Score: 1

    And where does the payload land on the 1-in-100 launches that the orbital insertion motor fails?

    Pretty much the same place as the payload on a current launch if its insertion motor fails. Were you under the impression rocket-based launches don't use insertion motors?

    Not quite. Current launch technology (read: rockets) are powered through much of the atmospheric flight. MECO occurs outside the atmosphere, and the craft's flight path takes it over uninhabited areas for the thousand KM until it is outside the atmosphere. Therefore, at no point is the vehicle on a trajectory such that if it looses power, it will intersect the Earth in an inhabited area. The balistic tragectory of the 'Slingatron', however, does bisect the Earth at roughly (due to atmospheric drag) the same place where it was launched from. Also, one needs to take into account the possibility that the payload will leave the muzzle at lower than expected velocity. Thus, an entire great circle of the Earth, several tens or hundreds of kilometers wide, potentially falls within the craft range.

    The insertion motor isn't necessarily a single-purpose item; for example, the Shuttle used the same motors for insertion that it used for the rest of its on-orbit maneuvers...but one way or another, you either insert or you come back down.

    Yes, I am aware of the functions of the OMS. And I believe that there was an abort mode for failure of the OMS, though it was not an OTA.

    TFA points out that it will have to have an orbital insertion motor on board.

    And where does the payload land on the 1-in-100 launches that the orbital insertion motor fails? At what speed, with how much kinetic energy, does it hit?

    Note that current space vehicles, even man-rated ones, have about a 1-in-80 failure rate.

    Or a PS/2 connector that the user tried to force in by twisting motion instead of just looking at the end to determine which way to put it.

    I once watched in horror as a Post Office clerk did that to her keyboard (nice Cherry switches it looked like) while I was in line. She was forcing and twisting for a good ten seconds before I snapped and stopped her. The pins looked like my daughter's braided hair. I was able to straigten them out by sliding a mechanical pencil without the lead over each pin and carefully bend it back to place.

    Hi Eric! As much has I appreciate your competence and your attention to detail, is it not possible (or even plausible) that insidious code such as that found in The Underhanded C Contest might have been passed in under your nose?

    Of course, it is reasonable to assume that the SE Linux code would be especially vetted for backdoors, and thus other areas of the kernel might make for less-eyes-looking-for-issues cover for a backdoor. But considering how much code goes into the kernel, is it not possible that some innocuous-looking code may have gotten through?

    Of course, if SELinux or any other component is compromised (or the hardware), then it is safe to assume that _no_ operating environment is any better off.

  21. Re:Unit Tests on Ask Slashdot: How To Start Reading Other's Code? · · Score: 2

    If possible, I would try writing unit tests for the existing code. This tests your understanding of what you are reading and will come in handy later if you change the code. If unit tests already exist then I suggest that you read them since they will tell you the intention of each function.

    Unit tests are a lot like documentation: they will tell you what the code is _expected_ to do. (Not what the code actually _will_ do, especially in corner cases). Thus, if you are already digging in to see what any section of code is doing, document what you've found: write a unit test.
