  1. Not necessarily an easy fix on Hacked Tornado Sirens Taken Offline In Two Texas Cities Ahead of Major Storm (zdnet.com) · · Score: 5, Insightful

    You'd think the other cities in the area would have learned from this vulnerability and fixed the problem.

    Believe it or not, it's not at all unlikely that word of the problem never got to the right people. And even if they were aware of it it's not axiomatic that they would be able to fix the problem. They might not have the budget or it might require coordination with (possibly uncooperative) other municipalities or it might be technologically impossible to "fix" the problem with existing equipment and budget. Stuff like this usually requires budgeting and possibly even taxpayer approval and doesn't tend to happen overnight.

    Although that would require local governments to be competent.

    Sigh... Just because not everything happens perfectly all the time does not imply local government is incompetent. Did it occur to you that the tech involved might be old and that the taxpayers haven't approved the money to replace the equipment? It's entirely plausible they don't have the resources to deal with the problem even if they are aware of it.

    The meme that government is incompetent is really tired. No institution does everything perfectly, public or private. Just because they have a failure in one task it does not follow that they are generally incompetent. There are lots of things you don't do well either. Should we declare you to be incompetent every time you overlook something or don't handle it perfectly?

  2. From the photon point of view, there is no time, all path are instantaneous, short (human size) or astronomical (accross the observable universe), for the photon it ages exactly a perfectly zero seconds.

    I accept this as apparently factual. What I'm having trouble wrapping my brain around is the relationship between the statement above and how photons travel through spacetime if they do not experience time. Speed = distance / time and photons have the constant speed = c. But if time for them = 0 then that fundamental mathematical relationship breaks down and is undefined. (cannot divide by zero but we are essentially saying c=dist/0) My confusion is, how does a photon travel a distance through spacetime non-instantly (which it clearly does) if it does not experience time? Photons travel at a fixed rate through spacetime which is demonstrably not infinite and has time in the definition of that rate.

    I expect the answer to be some non-intuitive reference frame of the observer sort of answer or something about velocities in spacetime (as opposed to space) being constant but I can't seem to puzzle it out.

  3. Universe expanding on Astronomers Discover 83 Supermassive Black Holes at the Edge of the Universe (cnet.com) · · Score: 5, Informative

    Light scatters in all directions (for the most part) from the origin of a single point of event.

    No, a photon will travel in a straight line from it's point of origin unless acted upon by an outside force. You are describing what happens to the innumerable photons that are emitted from a typical light source which is not the same thing. The photons that we see from these distant sources have traveled a long distance in a straight line (*) to get to us.

    (* straight in this context is not the same Euclidean geometry straight line you might have learned about in high school)

    So if it happened 13 billions year ago, how is it still observable?

    Because the universe expanded faster than the speed of light. Space itself is expanding to this day and so some light that was emitted a long time ago is just now reaching us. Some light that was emitted a long time ago will never reach us because it's too far away and space is expanding too fast for it to ever get to us.

  4. The cops are overworked people who get rewarded (promotions, more pay, peer respect) by results. Therefore they will take a two-dimensional view through a three-dimensional person, say "this 2D line fits this image", and stitch you up.

    Sometimes that is true and there is evidence to support that point of view in many places. But I happen to be personal friends with a number of cops and that description is not one size fits all. Not even close. A lot of them really are genuine public servants trying to do a good job. Their incentives have been unfortunately warped in an unfortunate direction sometimes but most of them that I've interacted with are aware of this fact and try their best to not be influenced by it when it happens. They aren't robots with no awareness of the social implications of what they are asked to do. It's actually because of that fact that when they do step over the line and start violating civil rights that it becomes that much more inexcusable because in most cases they know what they are doing is wrong.

    Yes, and it would appear that being a man of the cloth provides you absolutely zero credibility these days with regards to that as well.

    Why on earth should being a "man of the cloth" provide any special credibility? If anything it should be a strike against them given that they are in most cases literally selling a false and/or unverifiable claims of the supernatural. (those churches get built with real money that came from someone and someone pays the pastor's salary) They get away with it mostly because of social tradition but it's not difficult to make the case that what they are doing fits the description of fraud or at the very least a hoax. I'm not saying this guy is (intentionally) doing anything reprehensible but he doesn't deserve any special trust or credibility just because he preaches on Sunday.

  7. You'd think a pastor would be able to trust that his word would be taken seriously and in good faith, but not even our pillars of the community get the benefit of the doubt anymore.

    Why should being a pastor give anyone a pass? Someone who makes their living telling people that they should believe in an invisible man in the sky and a special book and give the church money or they will burn can easily be interpreted as a con man. No I don't really think that this person is a con artist (not intentionally anyway) but I'm puzzled by people who think being a religious leader somehow makes a person automatically trustworthy or a "pillar of the community". If anything I regard religious leaders as more suspect than most because they are selling hope on a false (or at least unverifiable) premise. Many religious leaders abuse the trust placed in them - see how the Catholic church continues to employ and protect pedophiles for a prominent example.

    I fully agree that this case was handled extremely badly and that this guy probably is a good and decent person. I'm fully aware that Wells Fargo is a company run by untrustworthy asshats with plenty of evidence to back that up. I don't agree that his choice of vocation should grant him any special privileges any more than you or me. That's how abuses of position and power happen.

    The police are not on your side, unfortunately. Don't talk to them without a lawyer, you will get burned.

    You are correct that they are not on your side and that you should be very careful in your dealings with them. However it is no axiomatic that you will get burned. Most of the time the cops are decent people trying their best to do the right thing. The problem is you can't tell when they aren't so you have to defend yourself by being careful in your dealings with them because it can backfire horribly if you aren't careful.

    It added that the App Store has generated $120 billion for developers while offering users a secure platform, and that Spotify is seeking to side to sidestep the rules that every other app follows.

    I always laugh when they quote revenue figures instead of profit. It doesn't matter how much revenue they generated if it isn't making any profit. As a professor of mine once said, you can make a LOT of revenue selling $2 bills for $1 - you just won't be in business very long doing it. You see this all the time in entrepreneurial magazines. They'll quote how much revenue some new business is doing and leave out the fact they are losing money hand over fist.

    I don't have a dog in this fight. I don't use Spotify so I don't really care what they do. My initial impulse is that if Spotify wants to use Apple's platform then Apple gets to charge whatever they want. If Spotify doesn't like it then that isn't Apple's problem. I doubt Spotify would do Apple a solid if the roles were reversed. Trying to compete head to head with Apple on Apple's platform doesn't seem like a recipe for success.

  9. Not such a crazy idea on Consumer Groups Want To Tax Facebook To Save Journalism (vice.com) · · Score: 1

    If people like journalism a lot they will pay for it.

    Why do you think that? They never have. Most journalism in the last 100 years was not primarily paid for by the end consumer but by advertisements. Most journalism that has tried to bill the end reader directly hasn't worked out because the economic model doesn't work very well.

    Think about it for a second. How do you assign a value to information you don't have yet? That's what selling stories It's impossible both for buyer and seller. I don't know what a piece of information is worth until I actually have that information and at that point you can't sell it to me. But a journalist has no way to know what value I assign to a particular bit of information or story. Any price they charge is a pure guess. Newspapers get around this by bundling a wide variety of data in the hopes that I will trust that some of it will be valuable to me. They do not and cannot know what value I will place on any given story so price setting is basically impossible. Advertising works because the advertiser doesn't really care about the value of the information, they just want eyeballs for a given demographic. So the newspapers basically give away the information and make their money from people who don't actually care about the story content.

    Why should a new tax have to look after any normal "job"?

    Lots of important and necessary jobs are supported by tax dollars including but not limited to police, fire fighters, road construction workers, teachers, soldiers, and many many more. Journalism is unquestionably important and necessary in a free society. I'm not saying we should or shouldn't have tax supported journalism but it's not like we don't support LOTS of "normal" jobs with tax dollars already. Some of our best quality journalism (NPR and PBS) is already supported by tax dollars.

    Not nearly as useful as having exposure to at least *some* sunlight in the morning before a person start's their work day.

    Disagree. It is FAR more useful to me to have the extra hour of daylight in the evening and I think most others

    Exposure to even just 15 minutes of sunlight in the morning boosts seratonin levels, which in turn boosts melatonin production in the evening and is vital for having healthy and restful sleep...

    That's fine but DST doesn't really impact this. Sunrise where I live on Dec 21 last year was 8:01am. Most people are already at work by that point of the day. Speaking locally, our school district starts their day before the sun rises for a sizable chunk of the school year when standard time is in effect. DST would not change this at all.

    Furthermore any improvements from the cycle you mention are typically drowned out by other effects including but not limited to electronic device exposure, social schedules, indoor lighting, and a host of other factors. The extremely modest improvement in sleep by some people from a few minutes of morning daylight is not nearly enough justification.

    You're talking about a "nice to have", but comparing it to something that we are biologically adapted to, which is to function primarily during the day.... well, as I've said before on this subject, evolution is not a democracy.

    No YOU are talking about a "nice to have". The adaptation you are talking about is an extremely mild one that we can and do routinely ignore.

    Why can't the individual States decide?

    Because that's the way the laws were written a few decades back when they implemented the current system. Not saying it is good or bad, just that that's what happened. Canada evidently wrote their laws differently which is neither better nor worse - just a different solution to the same problem. For whatever reason the federal law in the US allows states to opt out of DST permanently but does not permit opting in permanently. Not sure why but that's what happened. Since this is a federal law it requires congress to change it.

    There is evidently a workaround that at least one state is considering which is to move their time zone to the next one over (which states evidently can do) and then opt out of DST. Same effect on a technicality in the law.

    For the record I'm STRONGLY in favor of DST all year round. More daylight in the evening is a good thing.

    No. By definition sound cannot pass through a vacuum. Oversimplifying here but sound is defined as a pressure wave through a medium. No medium = no sound.

    If sound itself has mass, then sound itself isn't a vacuum..

    Probably an imprecise statement. It's not that sound has mass so much as that it carries energy which has an effect on mass of the medium through which it travels. I've never really thought about it explicitly but it makes some sense that sound and mass would have some relationship. (E=mc^2 and all that)

    If you get into the weeds of it, mass doesn't actually mean what your intuition probably tells you. Particles don't actually have a mass that is a single value. What we think of as mass is really just the expected value but at any given time it can vary according to a probability distribution. Also there is the fact that if you add up the weight of the particles in a molecule it's common for the weight of the molecule to be different from the weight of it's constituent particles. Energy into our out of a system can often affect mass in some subtle and not so subtle ways.

    I'm rather confident the appropriate regulators will conduct an appropriate investigation and figure the problem out. In the mean time the actual risk is remarkably low and not worthy of panicking over.

    What it appears to be is simply investors suggesting that eBay focus on its core business and ditch distractions.

    Possible but doubtful. Usually the argument goes something like saying the company would be worth more split up than it is as a single unit. Frequently this argument is used against conglomerates. This argument is sometimes correct but it tends to get over used and it's not at all clear if it applies here. Wouldn't surprise me either way.

    Ebay is also adding two directors to its board, including Jesse Cohn of Elliott Management, a hedge fund that disclosed a 4% stake in the company in January and began agitating for change.

Some rich hedge fund guy sees a chance to squeeze a company by threatening a proxy fight or other forms of pressure on management after buying a significant but still single digit percent stake in the company. Usually happens in companies whose stock price is depressed somewhat.
