Try this lip reading exercise on someone: Mouth the phrase "Island view" and ask them what you said. Nearly everyone will answer "I love you".
Lip reading is handy if you can do it, but isn't useful for communication. I know some deaf people, so I've always wanted to learn sign language so I can talk with them (that is we hang out in the same circles, but since we don't share a language we only communicate when there is an interpreter - formal situations where we are addressing everyone).
20kHz is the upper limit of continuous hearing. Most people (even those almost deaf) can hear a few discrete frequencies much higher than that. This depends on how the resonant frequencies, and your particular inner ear arrangement come together.
Whomever makes the positive assertion (i.e. something exists) has the burden of proof.
Only if that person wishes to convince others of it. I am satisfied with my belief in God. Many people will not believe the evidence that I present for my belief - which I am well aware cannot be done in a scientifically rigorous fashion. That does not mean my belief is wrong.
I am not trying to convert you directly. I would love to convert you, but right now you are nonconvertible, so it would be a waste of my (and your) time to try.
Are you sure? I avoid movies and don't own a TV, but of the few I've seen any part of, they use the family of the dead good guy to make the violence more horrible. Seeing the family of the good guy deal with the loss enhances the horror - perhaps more than the violence itself. (More time might be spent on the violence, glimpses of the family are enough to get the point across)
As for the bad guys, their families may be in bad shape without the bad guy, but they were in bad shape before, so it doesn't matter. In fact without the bad guy around they may have a chance to recover - speaking from experience, I know the family of one bad guy, and they are glad the world is rid of him. (child porn is what the law got him on - he died in prison)
I can't speak for every situation. I can speak for the ones I've seen, and the above seems to be the rule.
Let me paint a profile, tell me how well it fits: You are a male between 18 and 30. Most of your friends, and thus most of the people you talk to are the same (though you may have a number of female friends in the same age group.
If the above is true, then it is no surprise. Plenty of stories on slashdot over the years have remarked on how the 18-25 male demographic is watching very little TV, and the channels mentioned are of the few that get any following at all.
Sadly, while important, this demographic is not the majority of people. Thus the channels you mention are not in the most popular list despite being important to you and your friends. (Though they are very popular)
In short, you are mistaking your group for a representative sample of the population in general, when it is now.
Working through your code to see when a file handle is done with and can be closed is exactly as difficult as working through the code to see where memory is done with and can be freed. In most cases when manually managing memory you can tell exactly when you are done with it. There are a few cases where it is hard. Likewise in most cases you know when you are done with a file handle, but in a few cases it is hard to know exactly when you are done.
In one piece of code I maintain we pass around the handle to the config file. It can be hard to figure out where we are done with this handle, as so many classes need to initialize themself from the file. (I suspect there is some bad design in there, but it works so it isn't a priority to fix)
With C++ we use RAII, which ties memory with the handle. We never use the raw handle - except in the class. The class is a wrapper for the file, and thus it doesn't have any read/write methods. It has some getFoo/setFoo methods, that read/write the file. The file format can (and has) changed, but the format is abstracted so we don't have to modify other code. In other words good programming practice means you already have the resource limited to one class that manages it, so why not tie the memory management for that class to the management of the handle that the class manages?
In short in C++ we tie memory with resources, because it is an easy thing to do. With smart pointers, and stack object allocation, we can be sure that the resource is released when required without thinking. In most cases stack allocation and smart pointers is just as good as GC, but without the overhead. In the few cases where something more complex is required, C++ allows smart programmers to do the more complex operation manually.
There have been many good suggestions. However a warning is important: go for the early stuff the authors wrote, not what they write after they quit their day job. A few (Andre Norton comes to mind) managed to continuously write quality books. However many authors do not. (Mercedes Lackey) Those latter authors often get worse and worse over time.
I wish publishers had the nerve to stand up to established authors and tell them that this garbage would never have been printed if they were new, so why inflict it on fans now? Then demand they spend another year or so turning it into a great book. (Sadly there is no money in that)
I keep going back to names I love, only to be disappointed. I try new names once in a while, but that is no better (the quality might be better, but it isn't the type of book I want).
I do not have direct experience in big databases. I work with backups (over the years for several different companies). I cannot say if those big servers are justified in any given case. I can tell you the justification they gave to me. They seem smart, but I'm easily fooled.
Even then, I stand by my comment that there is a level the PostgreSQL/mySQL just doesn't scale to. If oracle will meet your needs is a different matter, though generally it is accepted that it does scale better. At a great cost, but if you really need a big database you pay the price whatever it is.
Plastics do not have to be made from oil. Oil is just cheap, so that is what they use. Farmers are promoting plastics made from corn. I've heard of soy based plastics too, but can't find a link. Pot fans like to point out that Hemp can be turned into plastic.
Corn based plastics are generally bio-degradable, which is often an advantage.
This is the worst case of misinformation I've ever seen on slashdot. The only part where you are correct is compression ratios and air-fuel ratios.
Ethanol burns BETTER in a "gasoline" engine than gasoline - if the engine is designed for ethanol. (Mess up the air/fuel or compression ratio and you can have problems) It is cleaner, burning, and higher octane.
Ethanol contains about 2/3rds of the energy as the same volume of gasoline. However because ethanol burns better (in an ethanol engine, a gas engine conversion will not see this efficiency) it will get the same fuel milage, and/or more power. Saab has already demonstraited such a car.
A car designed to run on ethanol or gas will generally see about a 10% loss of fuel economy when running on ethanol, despite the significantly greater loss of energy in the fuel.
There is some oil behind the donut and burger joints. However most of it is already claimed, so taking it is stealing! You can often get permission to take it, but be careful, many managers are not the owner, and thus not aware that someone else has already bought the oil!
Used oil processors know about biodiesel, and they have been collecting oil from behind those restaurants for years. (10 years ago they paid about $.05/gallon for it) They will no look kindly on your stealing of their oil.
The other problem is there isn't that much. There is enough oil for one or two people in each community. There isn't enough oil for everyone though, and in fact with the recent interest in biodiesel, there is generally more demand than supply already.
Still, if you can find a place to get it, there is a lot of used oil behind these places - on a personal scale.
True, but mostly because all the kids leave the Plains States when they grow up. A few take over the family farm (and thus have jobs), while those without jobs are smart enough leave the small town they grew up in for someplace where there are more opportunities.
Many (not all..) of the Plains states have great education, if any was a separate country, they would score with the top 5 countries in education (depending of course no how the test is given). Their kids are too smart to stick around someplace where there is no chance of getting a job.
Or so some women tell me. restrooms.org (Link is work safe, but from afar is looks like it is not, so don't try it. For that matter if you are a male you won't find anything interesting here)
To correctly wash your hands: do to the towel dispenser and unroll enough towel to dry your hands when done - leave the towel hanging. (if the towel is not on a roll you skip this step). Turn the water on, and adjust to the temperature you like. Wet hands. put soap on hands. Lather for at least 30 seconds, making sure to get the spaces between fingers, and under nails (as best you can). Rinse hands. Remove towel and dry hands. Use towel to turn off faucet. Throw towel away. Leave bathroom by push on door with your shoulder (the doors are supposed to open out, if not use the towel to open door, then your foot holds the door open while you throw the towel at the can).
This is easier than it sounds. I always do it this way, but mostly because I like to confuse other people when they see me do it.
Essentially none. Gas is not used in the main tractors anymore (diesel is more efficient), is not an ingredient in fertilizer (though some is made from oil), not is it used in distillation (natural gas, coal, or methane - more on this latter).
Ethanol production is energy positive. New factories get about a 1.67:1 energy in/energy out ratio when all factors are properly added in. (One "researcher" from California can't add the right numbers though, so he doesn't get this one) Much better ratios have been achieved in the lab, but they are not ready for production yet.
Did you notice I mentioned methane as a fuel for distillation? Still experimental, but it shows great promise - you locate the ethanol plant next to a beef feedlot, feed the waste from the cattle, then take the waste (manure) from the cattle and turn it into methane, which fuels the distillation. Really cool process and I'd like to see more of it.
How often do you call a plumber? Not often if your plumbing was done right in the first place. There is not enough demand for a plumber in my neighborhood for one to set up shop. Plumbers can only make their business work if they can cover a fairly large area.
In many parts of the US yearly rainfall during the 1980's was less than the worst year during the dust bowl. Farmers learned from the depression, and they changed to farming techniques that work in their area. A drought hurts, but not nearly as much as it used to.
Last I checked there was only one car for sale in the US that got better than 50MPG: the Honda Insight, which is rated for a max of 2 people. That SUV
(which gets closer to 20mpg, though I agree that is bad) will haul 6 people. Divide it out, and a per person when full. The SUV can also haul around a lot more cargo, which is handy from time to time.
So if you need to haul a load even once in a while, haul a family once in a while, or need 4 wheel drive once in a while; the question is can you justify the second car as well. I did the math - it pays for me, but I drive 100 miles/day, and then I only can justify it for a cheap used car, not a new car.
When my commute was half that it didn't pay.
There are a couple cars that get in the 40mpg, but not many. There are laws of physics that make it really hard to get that high, without compromises that most people do not wish to make.
My solution to high gas prices is to mi 50/50 ethanol/gas in my cars (My cars don't run right with more ethanol than that).
By your definition C++ is more safe than Java. C++ when used correctly uses STD:string for all buffer operations, and this makes C++ just as safe as Java. C++ also allows RAII (Java cannot - at least not in a clean way), which makes it safer.
There are several good C string libraries that do not allow buffer overflows. Thus C is now just as safe as Java.
Of course if you are stupid it is slightly easier to create a buffer overflow in C/C++ than Java, but that is not a factor for you. You like safe programs, and stupid programmers will never write safe programs, no matter what the language.
In my experience, the culture of C/C++ is more attuned to security problems, and that helps prevent the rest of the problems. The Java culture in my experience has not learned to pay attention.
BTW, if you like programs done in a secure language, does that mean you insist that everything on you system be written in e?
Most estimates place linux/BSD as nearly as popular on the desktop as the Mac. It is hard to measure, because most people just download what they want, but there are plenty of users. It isn't just college kids - many programmers run Unix desktops (mostly KDE or GNOME, but there are others). If your programs target Microsoft Windows, than you run that. If you programs are embedded you can run whatever is handy - Linux is very popular in the embedded world, and those working on such systems use linux on the desktop.
Linux is doing very nicely in the server room. Once again the numbers are hard to count, though companies are more likely to have bought something countable for the backroom. You don't see these systems though as they are locked behind secure doors, and only authorized people are allowed to see them.
I don't care if J. random Luser runs my programs or not. He is not paying me, if he uses them great. If not it doesn't cost me anything. I am not a zealot, I just use what works for me.
Proper C++ does not get buffer overflows. The STL does not allow them. Even with C code, buffer overflows are rare in new code, as programmers have learned the hard way to be careful to prevent them.
Historically buffer overflows have accounted for about half of all successful attacks. Secure programming is much more than buffers, your attitude that it is the most common problem makes it more likely that programmers will ignore the very real security holes that are not buffer related.
Java does not allow RAII, which solves a large class of errors that C++ cannot have.
The bottom line is stupid programmers can write insecure software in any language. Smart programmers look for a language that helps, but they know that even perfect tools can be subverted if they are not careful.
Read the legalize of both licenses. I cannot use java for my projects at work (an embedded system), because the license will not allow me to distribute it. For GNU software there are requirements that management doesn't like (but not a big deal as we are careful not to 'taint' our code), but we can distribute it with the product.
No, it is still infringement to have a copyrighted game on the web. Those notices are correct.
The problem is that copyright lasts far too long, not that they are being told to take down copyright games. It should be that those downloads would be legal, even if the company was trying to sell them retail.
Apple latter admitted they chose a task that was specifically easier with a mouse.
I can't recall exactly, but I think it was replace a sentence in a document, where it starts in the middle of one line and continues onto the next, but there is more after it. Most keyboard shortcuts do not work as well for the replacement.
The key is Fortune-500. When your database gets very large you will need full-time administrators watching it. You will need something that scales to big iron (million dollar servers), with good roll-over plans. Oracle does this well. PostgreSQL is great, but it doesn't scale up that far (yet).
For smaller systems (even within Fortun-500) you don't need Oracle, but odds are you have it somewhere, complete with all those admins, so using Oracle isn't a big deal. Sure PostgreSQL could do the job, but why hire an admin for that when you already have Oracle admins?
