The "more" correct way to write such code is:
if (ptr!=NULL){...}
Ive worked at proyects where that was enforced. It really doesnt matter in C because NULL is defined to be zero, but its better to use "ptr!=NULL" anyways, since ptr is not a boolean value. Its an abuse of the fact that NULL==0 to write "!ptr".
Ok, most comments are heavily critizising carbon credits, so, risking being bashed, I will write a little about the goods of carbon credits, from a perspective of a peruvian citizen. First, of course its not the ideal solution. Many in slashdot want either ideal or nothing. The best solution is for factories to stop polluting. However, in the real world, this is not currently achievable, as most of us continue to buy products that we ask those factories to make for us. Factories are just the intermediaries, we are the ones that demand more stuff. if you really want *factories* to stop polluting, *stop buying* their stuff, reduce, reuse, and recycle, and have less kids.
That said, the Kyoto protocol is at least a starting point, which formalized the mechanism for carbon credits. its a way for factories to continue polluting, BUT with two new advantages: 1) Some countries now put a price on that pollution, and factories now must pay for that, or must reduce their pollution. The best incentive is always money. In Europe this does work. And 2) not only do they have to pay, but that money goes towards projects that are good for the environment. As an example, here in Peru where I live, its actually a good business to plant and maintain a forest, because we get $ from carbon credits. This would have been impossible before Kyoto, and I can tell you first-hand that nobody gives a crap here about forests unless they receive some money in exchange, and the government does nothing to stop deforestation, so its left to private business to do something. In fact our rainforest is being heavily devastated mostly by coca plantations that destroy it. At least the carbon credits offset that a little bit. Hopefully as the cost of a carbon credit goes up, so will the business of making and maintaining forests.
I also have a lot of criticism for carbon credits, but nobody was saying what its good for, so I had to.
cool, email me at zmandel on the google mail system.
I think your disposition would be more important than your grades. Squeak is not hard to learn, after all its meant to be used by kids, and, in any case, we can follow a scripted class. I'm not interviewing for candidates, I will accept any help offered.
Regarding which one looks better for a Phd... I think volunteer work always looks good on any resume, and even better on real-life karma. Not everything has to be research and theory, we can contribute to the world in other ways too.
People in this orpahage are very very poor, I never saw that level of poverty in the 11 years I lived in the USA. Some days the kids dont even have food to eat, since they rely on volunteer work and donations:(
If you think you are not qualified, I'm not sure what to think of the orthodontist that currently teaches the kids computer skills.
Ok, a little off-topic but it would also look great on your resume. Come to Peru and help me teach programming to orphan kids in Peru. Im building a course in squeak (smalltalk, like LOGO on drugs:) to teach programming to the kids. The orphanage has over 630 kids and is all volunteer-run, with some volunteers living inside, mostly europeans. Watch some videos of the orphanage, its a youtube playlist and the last 2 videos are in english. I also have a software business with many years of experience working as a C++ programmer in top US software companies, and might be able to teach you a trick or two.
Ok,I didnt think people would reply to my comment, so Ill explain some of the steps. The whole machine was locked with administrative rights, the was no address bar or keyboard, and the webpage was in fullscreen. I right-clicked and most was disabled, but "Print" was enabled. In the print dialog, you couldnt do much, but one of the tabs had "print to file". When it asked me to select a file location, some administrative right would not allow me to select anything in the "browse" dialog. At that point, the start menu appeared because the browser left full-screen mode (Im sure an IE bug), but it was empty. You could, however, right-click it, and a "scan for viruses" option was available. Selecting it took me to another dialog where most actions got an error from administrative rights. But one tab had an "exceptions" button. Playing arround with the options, I finally got to another "browse" dialog, and this one had the "network" shortcut on the left pane of the browse (windows vista). Bingo. I could navigate the entire network down to individual files on individual machines. Their network was huge, it had hundreds of domains. Ive left some steps out in case a fello[w/n] peruvian reads this, though probably they already fixed it. Its the largest bank in Peru. The fact that the start menu was empty, and that I got several errors along the way regarding administrative rights means that someone took the time to try to lock it down pretty hard, except they forgot or never thought that the right-click could eventually give me access to important stuff.
Ok, I didnt want to make my post too long, but, there was nowhere to paste to. The webpage was in fullscreen mode without address bar, and you couldnt get out of it.
I live in Lima Peru. Last week a teller at my bank made me wait 10 minutes while she waited for the safe to open to give me some cash. In the meantime I went to a computer terminal without a keyboard, and access to only a webpage with the bank rates (windows, no start menu, no access to desktop etc). The machine was supposedly locked so that you couldnt navigate away or do anything except scroll the page and click a few links. Well, they forgot do disable right-click. 7 steps later I was able to access their internal network, and had access to a lot of internal information on individual machines. I went to the branch manager and showed him. He was surprised and embarassed, and took note of the steps I took. It was amazing how easy was to do it. The 7 steps were clever, but not impossible.
Science already has plenty of smart people. What we really need it to have science-smart people in other fields, like psychology, sociology, etc, where people cant even do simple statistics or research. Thanks.
from Wikipedia: In the real world, this phenomenon would be as if you called a friend to ask for directions to his house, and he gave you a set of directions that worked no matter where you started from.

Take a look at modified webcams for long exposure, plus software that averages multiple images to clean up noise. They are well within your budget (under $500) and you can take excelent, clean pictures from what Ive seen on the web. For example look at http://astronomiser.co.uk/cams.htm for a website that sells the mod-ed webcams, or you can do it yourself (http://sweiller.free.fr/VP-SC.html). Looks like a guy named Stephen Chambers discovered this, his website has a lot of information about it: http://www.pmdo.com/
Ive come across this problem many times over the years. I can give you some advice in Windows, which is where I have the most experience:
To reuse UI code easily, use a library that exposes the Win32 GUI API as a class hierarchy, like MFC. You can derive from classes to specialize a control, and reuse the base class handlers and such.
To reuse the UI itelf, use a "sub-control", to do that easily in windows create a dialog without caption, put the controls you want in the dialog, and in properties make sure to set "control" and "control parent". Then put the code as you would normally do with a modless dialog (there are a few gotchas but once you get them all in a base class you dont need to worry about those anymore). This is like a cheap version of an activex control.
Also, In MFC and other libraries there is a mechanism added to the win32 api called message refleccion, which allows a message that is normally received by a parent window, to reflect back to the control itself. This allows you to have a windows control handle itself, and thus you can reuse it.
It is ridiculous to focus on "proofs", everything we know about the world is incomplete and imperfect. A concensus among the most informed and intelligent people in the world (i.e. "scientists") is something to take seriously. I dont know where you got all the crap you just made up regarding scientists.
I use one too. Its called "active seating" because you use your muscles to keep your balance, (after a while it becomes automatic) this gives them a workout and makes the area stronger, thus making it easier to keep a good posture.
One drawback, though: at least for the pilates ball I use, which I purchased at whole foods, after a while the ball gives in to your weight and becomes more bouncy. You can pump more air on it but it becomes larger so eventually you need to buy a new one and they are not cheap, like $30.
You are missing the point. we all know why its there, thats obvious. He is asking why its the *first* choice (the one closer to the mouse cursor) when its probably the last reason you would right-click a link (since you can just click it.)
Actually, the problem with carbon dating is not with nuclear theory. Some fungi and bacteria can produce C14, and can throw off the calculations of decay. This link to the talk.origins newsgroup talks about it: http://tinyurl.com/bwwfk/
Even if your argument is true, it applies to the Hiroshima bomb, and NOT the Nagasaki one. It is well known that both bombs used different methods and materials (Hiroshima's used uranium, and Nagasaki's used plutonium) to cause the explosion, and that the US wanted to try both methods.
The US didnt even give enough time to the Japanese to go on-site to the Hiroshima disaster area, assess the situation and surrender.
Another explanation to consider is that eating a lot at night, or close to going to sleep, affects digestion of food, which can affect quality of sleep.
Yet another one is that they wake up earlier because they are hungry and cant continue sleeping. I'm not obese, but that certainly applies to me. I may want to continue sleeping, but Im too hungry for breakfast and it distracts me from falling asleep again.
Many others have proposed other explanations. Its probably a combination of them, and makes the simple correlation in the study very weak.
I read this story last year, which talks about a super colony of Argentine ants spanning 3,600 miles through europe. A little exerpt from the article:
Swiss, French and Danish scientists believe they have found the largest cooperative unit of ants ever recorded.
The colony is 3,600 miles long, stretching from the Italian Riviera to northwest Spain. It consists of billions of Argentine ants living in millions of nests that cooperate with each other. Some ant colonies can achieve a cooperative effort which allows them to work as one single unit, and in essence, one being.
Ants from different nests normally fight. However, researchers assume the ants in the super colony are so genetically linked that they recognize each other, despite the fact that they are from different nests with different queens.
I was just researching this a few weeks ago, and found these adapters to be a cheaper option, prices range from $30 to $120 depending on the player model, and they carry most car and aftermarket stereos.
Note that its only an audio interface, it does not interface with the stereo display. However, its cheaper, and works in alpine and most other brands. Hooks up through the CD changer interface on the back.
