I did go vinyl for a short time, when both record players and records were dirt cheap. That is the big benefit of being trailing edge. But when the hipsters entered the scene and drove prices up, there were no benefits.
Oddly enough, some restaurants force customers to share meals. That is to say, customers can only order separate dishes and serve themselves according to their own tastes. Even more traditional American establishments will offer at least a few dishes in this fashion.
As for those that forbid it, I honestly don't see what their problem is as long as people don't bring in outside food. It is quite antisocial to suggest that people should not be able to accompany their friends in a restaurant just because they are sharing a dish.
I understand why the airlines price flights this way, and it benefits some consumers by reducing the cost of some flights. Yet the easily exploited flaw is a flaw of the business practice, not the consumer. If some consumers exploit it, there is no good reason to hold them accountable. It was the business' decision after all to use this practice, not the consumer's. If too many consumers exploit the practice, then the business should change the practice.
Put in other terms, using the courts to enforce the practice places too much control of a product or service that the consumer paid for into the hands of the vendor. Consumer's wouldn't be very happy if business told them they couldn't resell a product at a profit just because they bought it when there was a good sale, or if they couldn't split a meal because they bought the larger dish instead of two smaller ones. Why should they be happy about being told that they must use all of the tickets for a flight?
The space program has been, on average, 1.15% of the US budget. Giving it a proportional share of the debt means that it contributed 204 billion.
Even if you consider space exploration as entirely frivolous, it has only contributed 508 billion to the debt (before interest). That amounts to 2.85% of the debt.
Yes, the US needs to get its "house in order". Yes, NASA needs to produce better results in order to justify its existing budget. On the other hand, attacking the space program will do very little to address the debt problem. Actually, it will do very little to address the deficit. (Again assuming that space exploration is completely frivolous, it only accounted for 2.48% of the deficit in 2013.)
It's a symbolic gesture. I doubt that many people expect the president to learn programming while in office. They have many other affairs to take care of.
First of all, those older jets are upgraded while the F-35 is being delivered according to a contract. That's not government incompetence. That's contract law, and no respectable contractor is going to write an agreement where the specifications can change at the last minute. In all probability, the military has already accounted for this and has planned upgrades.
Second, very few people are saying that government should control healthcare. They are saying that the government should control health insurance. Other countries already do this and have had very positive outcomes.
I never said that they were a sport, and stuck the quotation marks around "sport" in the comment subject to imply they aren't. Video games do have certain elements of sports which may make them an interesting element as a demonstration sport.
I think it would be good as a demonstration sport for one of the games, if they select the game carefully to align with what the games are.
The thing is, the games are mostly about physical competition along with physical factors that have a strong psychological element such as endurance and reaction time. Video games are poor at the former but rely heavily upon the latter, which is why I think they would be excellent as a demonstration sport but not as an ongoing element of the games.
This study doesn't really address that since it is based upon a very narrow selection of devices (i.e. the iPad). Indeed, none of the studies that I have encountered have addressed that because they are based upon a narrow range of technologies. I have seen anecdotes suggesting that eink based devices are less disruptive to sleep cycles, but my opinion on that is: if it works for you, great, but don't attribute it to anything more than wishful thinking and selection bias.
A study like this doesn't apply to eink based readers because it doesn't isolate the cause. Is it the intensity or spectrum of the light? Is it our response to the type of device in question (e.g. iPads are more exciting than ereaders)? Is it the difference between the screen brightness and ambient light? For all we know it has something to do with polarization or how the screen is refreshed. While some of the variables that I mentioned are dubious, they are still unexamined variables so we cannot make a comparison across a broader range of devices than those studied. (Then there is the sample size...)
Reading the article may help: they are talking about small buses which often have a dedicated lane. There is, of course, a desire to use this for regular buses.
As for the difficulties presented by public transportation, I can assure you that there are many problems presented by private vehicles. Even if you ignore the need for high capacity roads to handle an a large number of vehicles, you also have to dedicate a large amount of infrastructure to parking (may that be straight out land use or parkades). Large numbers of vehicles being operated by people with different skill levels and motivations also make roads very unpredictable places, which increases the probability of accidents. A dependence upon vehicles also radically changes the social environment.
It sounds like you're more interested in having a gaming machine than you are in enjoying the games, thus the presumably high spec machine that needs to shed excess heat. Well, most games don't actually need that. Just tone down the settings, reenable your PC's power management settings, and enjoy the bloody games for their entertainment value.
If that's not enough, then it's time to consider other things. It may be a purely technical problem, such as cleaning out the system or replacing noisy fans. It may also be a social problem, i.e. your wife is trying to find time to spend with you when may be spending your time gaming.
If most of your applications are open source, switching to BSD will be fairly straight forward on that front. That's particularly since you're coming from Gentoo (i.e. you'll probably have to compile a lot of the software that you want to run under BSD).
The biggest hurdles are going to be the sorts of things that a generic question cannot address. Is your hardware compatible with the version of BSD that you've selected? Unlike Linux, where everyone is using the same kernel and has almost the same access to kernel modules, different implementations of BSD use different kernels. As such, selecting an implementation depends as much on low level details as it does on the userspace. (While I've pointed out hardware compatibility, any feature that is found in the kernel needs consideration.)
Another consideration is whether you're comfortable with managing BSD systems. Unlike hardware support, this is difficult to assess objectively. Some people like the core OS being a unified system that you update all at once. Other people like the piecemeal approach of Linux. Keep in mind that the core OS could mean everything from the kernel, to development tools, to the X server. (It does vary a bit from implementation to implementation.)
You will also run into a bunch of stuff that you'll have to relearn, particularly if you're accustomed to working in the shell. Software packaging and installation is the first one you'll bump into, but BSD also has it's own set of utilities. Some of these utilities are quite similar to the GNU utilities, but the extended functionality is quite different.
If you want to switch to BSD, I suggest doing it on a secondary computer first. If you run into specific issues, ask specific questions. Odds are that those issues can be resolved, but it will take time to sort through all of them. BSD can be an immense pleasure to use, but it involves a lot more than which applications are and aren't available.
Most startups need a moral compass in order to recruit and retain employees who are invested in the success of the company. If the startup doesn't offer that, there is a high probability that quality employees will move on when better opportunities arise. (Examples are higher pay, better benefits, or a more stable job. These are all things that startups find difficult to provide.) Depending upon their clients, it may also serve to separate the startup from the competiton.
Yet Uber (and the likes) are not your typical startups. Since they are trying operate in a highly regulated industry, and in an industry where the regulations vary from place to place, they are very politicized. Unfortunately politicized issues make it very difficult to have a clean fight because those with a vested interest have the existing power structures (politicians, courts, etc.) on their side.
If you live in the city, there's probably after school programs or summer programs geared towards kids and computers. Some are technical while others are creative, but most of them provide a mentor who guides groups of children through creative projects. Depending upon your child's personality, she may find it a much more appealing environment.
Perhaps it is a good idea to read Linux Voice before commenting upon it's value, simply based upon the merit that it is a magazine.
While certain aspects of a magzine do go out-of-date quickly, others don't. Nine month old news, not so great. Nine month old reviews are okay. They'll introduce you to a product, even if some information is outdated. Nine old month tutorials can be useful.
Magazines do have merits other than content. The flow of information is more paced. Reading the news daily (or even hourly) means that you are more likely to run into redundant details across multiple articles. It also means that there is less time to write comprehensive stories, verify details, and edit the material. I'm not saying that they're perfect, but you really have to wonder about the quality of a lot of the online media when they publish as much a day as a magazine publishes in a month. Actually, I don't have to wonder. I've gone to many sites where the articles range from terrible to excellent, primarily because the authors range from terrible to excellent. Yet they won't cut the terrible authors because it's more important to have a continuous stream of updates than it is to invest in quality.
Even if you did have something better to do, would you rather be testing and deploying security updates or cleaning up a security breach?
It is easy to be unhappy about security updates because of the implied security bug, a bug that shouldn't have been in there in the first place. Yet we also have to remember that people are investing a lot of time into discovering and exploiting design/implementation flaws because we invest so much into computers and networks. It doesn't matter whether the mistake shouldn't have passed the muster of code review or it it's so obscure that it would take security experts years to understand its implications, someone is going to find it. It is, unfortunately, something that we've been seeing a lot of lately and it is something that won't disappear in the future.
(We also shouldn't be targetting Microsoft because most platforms have seen critical security updates and even critical security breaches lately. It doesn't matter how proficient the developers are, nor does it matter who they work for. What matters is the value of the systems and data being compromised.)
The deficit they're talking about is around 1% to 2% of the annual production. Assuming that you sell the reserves prior to selling the new crops, and put the unsold new crops in reserve, the reserves could last for decades with none of the stock being over a year old.
Of course that is a highly simplified view, but it does allow for multi-year deficits without actually running out of cocoa. Of course a low reserve also means that there could be serious problems if the yields are particularly bad one year. (But at least it's just cocoa. A staple crop would be an entirely different issue.)
Either the eraser end or the tip of the pencil. The fact that a high school physics teacher couldn't answer the question doesn't surprise me. It isn't a high school level problem. It also isn't the sort of thing that would cause me to question everything that a teacher says. It simply represents a limit to the teacher's knowledge, rather than a teacher communicating incorrect information. It simply means that you have to take an extra step in learning: either looking for other resources or figure out the solution yourself.
Services like Uber, Lyft, and taxies woud end up increasing road usage since drivers have to drive to pick up their fare. The only infrastructure they reduce the demand for are parking lots.
Besides, public transit has not been for "people who couldn't afford private transport" for a very long time. At least that is the case in major urban centres, where people will gladly accepted a higher cost of living simply to ditch the car.
Many transit authorities have profitable bus routes, particularly in higher density areas. They bleed money on suburban routes, where it's difficult to fill a bus. Perhaps a better option would be to fund companies like Uber with taxpayer money in order to eliminate those suburban busses that transport few, if any, passengers.
(I'm saying that tongue-in-cheek, since such a system would be rife with abuse by both operators and customers. Still, there are cases where it could be cheaper if you could magically make abusing the system disappear.)
Cities that offer good transit service don't have to worry about the competition. Those transit services already offer fast and reliable service at a reasonable price.
On the other hand, cities that offer horrible transit service need the competition. They need to realize that poor coverage, poor scheduling, unreliable service, and drivers with poor safety records are unacceptable. If they don't realize that it is unacceptable, then maybe they should shutter their doors and let the private sector take over. (This coming from someone who normally supports a strong public sector.)
To give you an idea of what I mean: I work two jobs in a city with poor transit service, so I decided to sit down and do some math one day. The end result is that taking the bus cost significantly more than taking a taxi. That's a single person in a regulated cab, and not the shared-ride service mentioned here. Yes, a great part of the cost was from lost income. Yet it was real lost income in my case because I had to negotiate my work hours around transit. For other people, the loss of income will come in other forms: being unable to accept a job due to transit coverage or scheduling, or losing a job because unreliable service results in an unreliable employee. For other people it will result in a diminished quality of life, simply because much of their time is spent waiting for or being in transit.
(To give you an idea of how inefficient transit is in my city: if it takes 30 minutes to walk somewhere, you may as well walk since the bus is going to take longer. If you have to be somewhere at a particular time, you can usually increase that 30 minute walking radius to 1 hour because that bus that "arrives 10 minutes early" will end up arriving 10 minutes late so frequently that you will end up unemployed.)
There are plenty of high schools that teach people the basics of programming in the course of ten months. The advanced courses do a pretty good job of covering everything from languages to algorithms to software engineering. Yet I don't see businesses jumping at the prospects of hiring these graduates.
There's a reason for that: they only touch upon the basics because they only have time to touch upon the basics. While that may be enough to put together a website for a small business or create a basic smartphone/tablet app, only the tiniest minority will come away with the skills to make something as advanced as a salable indie game.
To do anything innovative, you need both the training and experience to handle the mathematics and design that goes into larger applications. That takes years, which is why university programs take years. Without that extra effort and the dedication behind it, very few people are going to be able to develop anything beyond the most basic program.
(Note: I'm not suggesting that the training and experience has to be formal, since a lot of self-studies have done amazing stuff in this field. Yet even teenagers who have created sophisticated programs have been building upon their skills for more than a year, never mind a few months.)
The motivation to get an SUV may be different from the motivation to get a burger, but willpower is a good word in both cases.
In some circles, an SUV is a status symbol. The people who buy them as a status symbol don't actually need an SUV, but they buy them because they think that an SUV reflects who they are or who they want to be. Well, they probably don't think in exactly those terms. They probably think of what they can do with it, just like I think of what I can do with a new computer. Either way though, that extra performance is about how we present ourselves to ourselves or to others rather than an actual need. Either way, if we can't afford it due to our income or the cost, we are less likely to buy it.
Note: I'm not saying that nobody uses an SUV. There are certainly people who will find an SUV more practical than a minivan or a pickup truck. Yet it is doubtful that the people who needed an SUV stopped buying SUV's in the first place. Similarly, I doubt that people who need a quick family meal while on the road would shun that Big Mac (which is what fast food is about, rather than as a regular meal replacement as we seem to see it as today).
That is actually a very good idea, and it is something that I would appreciate given that I sometimes have difficulty hearing dialogue over background noise.
However, that would also entail some sort of arrangement between device manufacturers and theaters since the only way it's going to happen is if they're guaranteed that the device cannot record audio and video in the theater. While I'm not against that in principle, I am against it in practice. (Telling a device, "no recording," is one thing. The layers of malware that they'd layer on top of that, and resulting loss of control of the device both inside and outside of theaters, makes me jittery to the point of paranoia.)
It depends upon how stable orbiting systems are formed. There has to be a transfer of angular momentum. That angular momentum is probably transferred via magnetic fields. The magnetic field needs something to interact with, such as ionized particles. Ionizing particles requires an energy source, such as a hot central body. For Jupiter and it's moons, that could very well be the Sun.
(Note: it has been a while since I studied this stuff, so I may be a bit off. But the most important point is that it is difficult to create stable orbiting bodies.)

Yet it is doubtful that the people who needed an SUV stopped buying SUV's in the first place. Similarly, I doubt that people who need a quick family meal while on the road would shun that Big Mac (which is what fast food is about, rather than as a regular meal replacement as we seem to see it as today).
That is actually a very good idea, and it is something that I would appreciate given that I sometimes have difficulty hearing dialogue over background noise.
However, that would also entail some sort of arrangement between device manufacturers and theaters since the only way it's going to happen is if they're guaranteed that the device cannot record audio and video in the theater. While I'm not against that in principle, I am against it in practice. (Telling a device, "no recording," is one thing. The layers of malware that they'd layer on top of that, and resulting loss of control of the device both inside and outside of theaters, makes me jittery to the point of paranoia.)
It depends upon how stable orbiting systems are formed. There has to be a transfer of angular momentum. That angular momentum is probably transferred via magnetic fields. The magnetic field needs something to interact with, such as ionized particles. Ionizing particles requires an energy source, such as a hot central body. For Jupiter and it's moons, that could very well be the Sun.
(Note: it has been a while since I studied this stuff, so I may be a bit off. But the most important point is that it is difficult to create stable orbiting bodies.)
