  1. Trust But Verify on Researchers Say a Breathalyzer Has Flaws, Casting Doubt On Countless Convictions (zdnet.com) · · Score: 4, Insightful

    So in most cases they use the breathalyzer along with a field sobriety test to determine if they should arrest a driver, after which they normally draw a blood sample for a more precise test. (In most states, drivers can refuse the tests and receive an automatic license suspension, though that's often not as bad as a conviction, but it doesn't preclude a conviction based on the sobriety test alone.)

    So we have lots of cases where there is both breathalyzer test data and blood test data. This gives a huge amount of data that can be correlated. Also, the times of the test should be recorded, so expected declines due to delays between the two tests can be computed. So all we need to do is gather up the data from a few years of use, and then we can see what the reliability of the breathalyzer is in comparison to the blood test.

    We know that any test can fail (equipment failure, cross contamination, operator error, etc.), but this will give solid data on the expected error.

  2. In Red Mars, they solved the resource problem of immortality by instituting a one child per couple family. If you do the math, each generation being 50% the size of the previous one with no deaths results in a doubling of the population. They proposed creating a market for the half child allowance each person receives, so those that didn't want children could sell to someone who did.

    Of course, that requires a very strong government, which has its own problems, but at least there are solutions.

    On the practical side, mutations will tend to accumulate over ever longer lifespans, resulting in an ever increasing opportunity to study cancer. We may see lots of people hitting 100, but not many reaching 200.

  3. Type 2 Spaces, Let the Computer Sort it Out on Are Two Spaces After a Period Better Than One? (arstechnica.com) · · Score: 4, Insightful

    Typing two spaces at the end of a sentence indicates a between-sentences gap, as opposed to a between-words gap. That may or may not be the same amount of space. If you're using a proportional font, then you're relying on the computer to handle the spacing, and this should be no different. Perhaps two spaces should kern together to be the equivalent of 1.2 spaces, and that sort of rule can be handled by the font.

    The problem is that determining the difference between the end of a sentence and a period that just ends an abbreviation is quite difficult. That's something that requires natural language analysis, not something simple like kerning that is part of the design of proportional fonts.

    So everyone should continue to learn to type with two spaces after a period. We know it's superior for fixed-space fonts. Computers should be taught to do the right thing for proportional fonts. If they don't, file a bug report.

    Not necessarily. First, for the top acts, even the listed ticket price keeps a lot of people out. Using the reverse auction system, scalpers are less likely to jump in, as it's harder for them to catch the right price and profit, so the real fans are more likely to end up purchasing tickets directly at a lower price.

  6. Better Ways to Eliminate Scalping on Aventus Blockchain-Based Ticketing System Aims To Wipe Out Ticket Touts (theguardian.com) · · Score: 3, Insightful

    The way I would eliminate scalping is to schedule a decreasing ticket price. Buy on the first day, and the prices are $1000. They drop $100 for each of the next four days. Then they drop $50 for the next 5 days. Then they drop more slowly as the event gets closer.

    Or something like that.

    The point is that if you buy them up early to scalp them, you'll have trouble making a profit. If the fans really want to pay $500 for front-row tickets, the artists (or their promoters) get the money, not the scalpers.

  7. Re:Privately owned cars should be banned on UK Car Industry On Alert Over Reports Some Hybrids Face a Ban (bbc.com) · · Score: 3, Interesting

    There are a lot of rural areas in the U.K., too. Sure, I can see a ban on private vehicles in areas with congestion issues. They could eliminate all urban parking entirely that way, which would allow for some really nice changes. Most urban dwellers won't likely need their own vehicles.

    But there's no need to ban private vehicle ownership altogether.

  8. 22 Years Out on UK Car Industry On Alert Over Reports Some Hybrids Face a Ban (bbc.com) · · Score: 5, Interesting

    So banning cars that can't do 50 miles all electric over twenty years from now is unrealistic and damaging for the industry now? That makes no sense. Perhaps if they were going to ban existing cars that can't do 50 miles all-electric in twenty years, then people would be just starting to think about that, as some cars last that long, but on average cars only last ten years. But that's not what they're talking about. The article clearly says it's for new vehicles.

    I doubt making changes in requirements for cars in ten years would be a problem. Most cars get a major refresh every five years or less, so there's plenty of time for manufacturers to adjust.

    Sure, the Prius is horrible as a plug-in hybrid, as it doesn't do a decent job of running all-electric (or so I've heard), but Toyota has decades to fix that.

    This proposed rule looks to be more descriptive than proscriptive. Does anyone really expect any manufacturer will still be selling vehicles for general use in twenty years that aren't at least mostly electric? That's not what the manufacturers themselves are saying. At the rate things are shifting, I doubt there will be many cars with tailpipes being sold new by 2030, let alone 2040 (but I'm an optimist).

  9. Likely Variants on Spectre on 'Next Generation' Flaws Found on Computer Processors (reuters.com) · · Score: 2

    It is likely that there are other bugs related to speculative execution that can leak data. For example, you could have code that leaks data through timing instead of through direct cache impact. You measure the number of cycles after writing clever code that consumes one more or less based on a bit of restricted data.

  10. I'll admit I don't know the technical specs, but it sounds like a solid solution. I would like to hear if anyone knows if there's a technical reason for not moving forward with it, or if it's just money and politics.

    No, we need warnings for certificates that aren't trusted. Otherwise SSL does nothing to prevent man-in-the-middle attacks.

    What would be ideal is to support secure DNS with certificates in the DNS. Then you know you have the right certificate and don't need any certificate authorities at all. Of course, you have to trust the secure DNS. so it's just pushing the trust problem down the road.

  12. 4K in Movie Theaters on 8K TVs Are Coming, But Don't Buy the Hype (engadget.com) · · Score: 1

    Most movie theaters now use digital projectors, and those are typically either 2K or 4K. Even IMAX digital is 2K or 4K. I don't usually hear people complaining about the resolution in theaters, so I have trouble seeing how going to 8K will improve the home experience.

  13. Fight for $15 on Many Amazon Warehouse Workers are on Food Stamps (theintercept.com) · · Score: 5, Interesting

    This is one of the main arguments for the left pushing "Fight for $15." If you're working for minimum wage, then you qualify for food stamps and other government assistance, so the government is essentially subsidizing employers who pay minimum wage.

    Here's the math: The federal minimum wage is $7.25. If you work 40 hours a week, 50 weeks a year, that's $14,500 a year. The Amazon wage listed in the summary of $24,300 correlates with $11.68/hour for 40 hours/50 weeks. Of course, the Amazon hourly rate is probably lower, but with overtime depending on demand.

    As to doing it on a CPU, I'm curious as to how it compares with x265, as I have a system that can't quite keep up with x265 in software for 1080p (older CPU and GPU). Would AV1 be better or worse?

    My company told me when I was hired (buried in some document) that salaries were considered trade secrets, and we weren't allowed to discuss them. I don't know if they have any legal footing there, especially when discussing them within the company. Also, we've been acquired by another company since then, so I don't know the current policy. But in any case, you may risk some retribution from your employer if they find out you're sharing salary information (potentially forcing them to pay more when the underpaid workers find out).

  22. Edge TV on Samsung's New TVs Are Almost Invisible (qz.com) · · Score: 3, Interesting

    Next up will be the Samsung Edge TV. It's just like the current TV, only the screen extends and curves a bit at the edges, so there is no black rectangle frame at the end of the screen. Sure, it's even more pointless than the edge on their phones, but when they're charging a premium for anything that makes them cooler than a TCL or Vizio TV, there's nothing they won't try.

    Now if they had a passive color E-Ink display or the like, that would be really cool. Then you don't have to feel guilty about the power when leaving the screen on to have it blend in with the wall (or appear to be a painting, or whatever). Of course, good luck getting such a display to handle motion and extreme contrast that makes for a quality television. And good luck getting such a display at anything resembling HDTV resolutions, let alone 4K.

    I still use Gentoo on my systems, but I'm increasingly worried as they seem to be struggling to keep all the packages current. I suspect the number of packages a distribution should have available is increasing over time, but the Gentoo community has shrunk, which is a dangerous combination.

    That said, having a source distribution makes running with local patches trivial. I also really like openrc, but I'll admit that that's in large part due to my extensive experience with it, so I really understand how it works.
