  1. Say I take a timestamp and add one nanosecond to it. That will increment the timestamp if I test near the start of the epoch. But eventually it will be far enough from the epoch that one nanosecond falls off the end of the mantissa and now this fails.

    You're limiting the concept of income to that which is produced through labor. But that's not the only source of income, or even primary source for the highest earners. There is also income via rents. Which has many forms, interest on borrowed money, dividends to investors, and rent for use of property.

    Someone who "makes $1,000,000" might not get any of that via labor, but entirely because what they own entitles them to it. While capitalism tells us that capital creates more value, someone who inherited a real estate empire or a billion dollar portfolio has done nothing to create any capital or any value.

    Consider that by flipping a few bits of ownership information, the investment that entitles someone who "makes $1,000,000" could be shifted to instead entitle another who "made $30,000" to that income. They go from $30,000 to $1,030,000 in an instant, but do no alter their life or production of tables in any way. And the former real estate baron goes from $1,000,000 to $0 in an instant, also without altering their life or anything they produce. Nothing produced has changed, no one has become more or less productive, yet a massive change in the distribution of wealth has occurred. In this case, creating economic value clearly is not related to income.

  3. Let's suppose that only one Starbucks patron in a million watches porn at Starbucks, and let's suppose that you've visited Starbucks four times daily, seven days per week, for 10 years. That's just over 100,000 visits. The probability that you'd have seen a porn-watcher in 100K visits is 9.5%.

    There's a flaw in the reasoning here. This assumes each time he goes to a Starbucks he observes exactly one other patron. They are usually more crowded than that, especially at times the OP is most likely to be visiting the.

    The real question that needs answering, is one more likely to observe someone else's porn at Starbucks or get hit by lightning?

  4. Is it really more accurate in practice? on FCC Paves the Way For Improved GPS Accuracy (theverge.com) · · Score: 1

    GPS + GLONASS has been around for a long time now.

    No one used anything but GPS because it was free and it worked well enough. But that made having GLONASS as an non-US-controlled alternative to GPS useless. It's there, but nothing uses it. So the Russians required cell phones to have it to be sold in Russia, which was the lacking motivation for GNSS vendors to support GLONASS and now everyone does.

    And is the result more accurate GNSS from the extra system? Not really. If you're in a location where GLONASS works better, then there's an improvement. But GPS is better most of the time. Adding the GLONASS position solution doesn't improve it. It just adds more error. Assuming you have good GPS reception, GPS alone is more accurate than GPS + GLONASS.

    It'll probably be the same with Galileo.

    It's also the case that the commodity GNSS chipsets didn't care about GLONASS support before they had to add it. They don't care about more accuracy. It's not something that sells phones.

    If they did care about accuracy, then GPS has new signals called L1c, L2 and L5. They are better than the old C/A signal everything uses. Been around for years. Using a dual band receiver to get L1+L2 or L1+L5 would allow cancelling out the ionospheric delay. That would provide the biggest increase in accuracy to GNSS that remains to be had (besides post-processing). Survey level GNSS systems do this. But commodity GNSS doesn't care. Won't sell more phones.

    Dialup standards progressed in a logical fashion from V.22 to V.32 to V.34 and so on. The bigger the number the faster the speed, so it made logical sense.

    Hardly. V.22 was 1200 bps. Then you've got V.23, which is... also 1200 bps. For 2400 bps, we go backward from V.23 to V.22bis. Faster than that you had HST, CSP, and ... V.24? Nope. V.22ter? Nope. Jump to V.32 9600 bps and then V.32bis at 14400 bps.

    And after that, any guesses as to what was after V.32bis? V.33? No. Maybe we jump by 10 again to V.42? Well, V.42 is a modem standard supported by modems of the time. But it's not a modulation standard but rather an orthogonal standard for data compression! So you've got combos like V.32 + V.42 and V.32bis + V.42, or V.32bis + V.42bit.

    This time we go to V.34 after V.23bis. But not immediately, first there is V.Fast and V.32terbo. Then we get to V.34 at 28,800 bps, later extended to 33.8k and called V.34bis or V.34+ or just V.34.

    Now we skip V.41, V.42, V.42bis, and V.44 because those are compression standards (don't forget MNP-5) and jump all the way to V.90 to get 56k.

    I used this to hack a WWIV based BBS system around 25 years ago. Heard about it from somewhere. What you did was place a file with a "..\..\" path into the archive and upload it to the BBS files section. The board would automatically unpack it on upload, or maybe you had to invoke a "download a file from inside a zip" feature on it, my memory is hazy on that. But it would unpack the zip, it would overwrite a executable that was part of the BBS software, and then when it ran that your trojan would run.

    Isn't a press release about this kind of like a press release about the concept of buffer overflow exploits?

  11. Indeed, I don't believe I know anything about those on SO when I response to a question. Perhaps if they are a native English speaker or not and a suspected native language.

    It seems like an interesting research problem that could be solved. Do users of SO know the marginalized group status of other users? Do they think they know, but they are wrong? Do they think they don't know, but really they subconsciously do know? It would seem the data is there. Histories of interactions, text analysis of comments, surveys of users, and then get some real data on users and see the correlations.

    Here's a possibility. Some members of "marginalized groups" expect preferential treatment. When no one knows they are in a marginalized group, they get treated exactly like everyone else. Since this is worse than they are used to, they view this as hostility.
