<p>Enforcement is the real issue, not the specific red lines, regardless of what Anthropic claims and news outlets repeat.<p>Verification requires access to classified logs. These logs would attract the spies of the whole world. Even if these logs are in principle for "past actions", in practice past logs (for war games, for example) would compromise future strategy.<p>Since these manual audits are too risky, the only alternative is to hard-code limits into the AI. But are we ready trust an AI to "judge" a mission and refuse to execute during a crisis?<p>Anthropic wanted technical enforcement, the Pentagon wanted trust.<p>It’s a choice between two bad options: an unaccountable military and an unreliable AI kill switch. They are both very dangerous, just in different ways.</p>

<p>Focusing solely on taxes misses the point that most people do not fully utilize "included" baggage allowances on domestic trips, and that is pure profit.<p>Let's assume a $40 bag fee: $25 cost to handle the bag, $3 tax, $12 profit.<p>If people pay for the bags separately, in addition to their $220 ticket, they will only pay for utilized bags, so for 1 bag, the profit will be $12.<p>If the $300 ticket bundle includes 2 allowed bags, but people only check 1 bag, then the profit is: $80 - 2<i>$6 (tax) - 1</i>$25 (cost) = $49 profit, more than 4 times bigger!<p>The real reason is the comparison sites as the HN commenters pointed out, but the result is not always bad, because the savings is real in many cases as people indeed would only pay for one bag on average ($220+$40 = $260) instead of $300.<p>I think airlines are much less happy with the separated fees than consumers, but once one airline does it, the others are forced to do it. The same happened with the international trips, which clearly has no tax reason. Many years ago it included 2 pieces of 70-pound bags, then 2 50-pound bags, then 1 50-pound bag, and now in many cases, on basic tickets, nothing at all.</p>

<p>The real question is why the insurance companies are pushing the annual exams very hard, not just in consumer ads, but using lots of incentives for primary care physicians.<p>One would assume they would not want to pay for unnecessary tests for healthy people.<p>So either their own research shows they save money with annual checkups in spite of what the article says, or more sinisterly, they do want to spend money to be able to justify higher premiums, because in several states they are required to spend around 80% of the premiums, and this is one easily plannable way.<p>Does anyone know? Perhaps someone working for an insurance company?</p>

<p>Plummeting sperm counts is a worldwide trend.<p>On the other hand, people in more industrial countries are exposed to different chemicals (BPA, FPOAs, flame retardants, food additives, etc.), than people in more agrarian countries (field chemicals, like fertilizers and pesticides). These chemicals are all harmful, but it's hard to blame a single class of them for a global problem.<p>If I had to pick a truly universal issue, I would say childhood and young adult obesity. Surprisingly, obesity is growing rapidly even in countries where hunger is also a problem.</p>

<p>People like the convenience of having their bookmarks and saved passwords available, so the Incognito mode serves a purpose, it's just not what its name implies. Only its name is a problem, the description on the starter page correctly describes the behavior.<p>"Guest Mode": (1) hides the identity on the internet, and (2) hides the activity on the local machine.<p>"Incognito window": (2 only) hides the activity on the local machine.<p>To clear the confusion, "Incognito mode" should simply be renamed "Ephemeral mode" or "Transient mode" or "No-Save mode".</p>

<p>This is probably less invention, more marketing.<p>Manipulating ions requires a lot of current. Drop an AA battery to a soup and nothing remarkable happens quickly, but lick the same battery and you will definitely feel it immediately.<p>If you do it while something sour/salty is in your mouth, your tongue may get confused, since it's only prepared to detect 5 flavors plus hot and cold, and it may simply assigns the extra feeling to the strongest sour/salty/umami taste currently experienced.<p>The electronics is probably just to cut the current when the two chopsticks touch to prevent short circuit.<p>There are similar articles from a few years ago, like this:

<p>It's just to emphasize that they may be lenient about some other tickets as long as they are way in the past, but they are not lenient about these ones.<p>These are reasonable conditions, but apparently they are not easy to pass.<p>I think the texting while driving is the more interesting one: a bunch of states don't care too much (Arizona, Montana, etc.), some others only impose a small $25 fine, so young people may not think about it as a huge obstacle to a high-paying job much later.</p>

<p>PHP's main problem is its very shallow learning curve.<p>The 5840 built-in functions provide easy ways to get many useful things done with minimal dabbling.<p>In other words, one can be a "scripter" instead of a "programmer", and for many projects that's 100% OK.<p>Other languages automatically filter out "scripters" from their field by demanding a certain level of mental abstraction to produce anything moderately useful.<p>While there is absolutely no difference between a good programmer using PHP, or a good programmer using any other language/environment, but there is a big difference between the median levels and below.<p>This in turn lowers the reputation of the field, and it becomes uncool to put PHP on one's resume, therefore the more capable programmers propagate out to other languages, which further lowers the median, etc.<p>This happened with Perl, too...</p>
