no, you're not going to have access to their systems.
You MAY be allowed access to some public API to query their systems, but that's as far as it goes.
And you'll have to negotiate with each of them separately to get access to those APIs (which may come at a price).

If you don't know that kind of things you're not ready to build something on the scale you seem to envision.

The reason we could live happily like that in the past was because we didn't know better. We didn't have the same knowledge that we do now... and if

Most people didn't live happily... In fact only those who didn't need to farm because they had serfs to do it for them and ruffians to terrorise those who objected to that who knew happiness...
We now call those "nobles", in fact they were little more than highway robbers with a sense for dramatic architecture.

> Do you think life would be better if we had start doing things the it ways years ago. Think

nope. We abandoned those ways because they were bad. Starvation, disease, low life expectancy, etc. etc.

> about it...if each of us had planted our own vegetation and food in general and then trade, would it be better?

Nope. We'd live shorter, die younger, be poorer, less healthy.

> How long do you think it could last?

They tried it in Cambodia under the Khmer Rouge. Lasted a few years, by which time 30% of the population was dead.

> Do you think we could gradually, become that way...or has the world become too advanced....too complexed...to greddy and too competetive to do so???...

Nothing greedy and competitive about it. Given the current population of the world the system you propose is impossible to implement.
There's just not enough land to go around for one thing.
Of course the introduction of such a system would rapidly cause the vast majority of the world population to die of exposure, disease, and starvation, curing that problem.
The rest would end up living in a feudal society, similar to the 1100s in Europe. Regional overlords with total control of everything, the population effectively their slaves.

> I want your honest opinion...would you embrace such a simple lifestyle?? You think you could adjust???

Noone living in a city today, and hardly anyone living …

I was enrolled in Judo classes so I might learn some skills to defend myself against the bullies at school. That didn't last long, the bullies were also in that Judo class and so had even more time to beat me up...
They signed me up for music lessons, which we gave up as I couldn't hold a tone.
I got signed up for a checkers club, stopped after a while as every other member was 50 years older than me.

There was little else in the way of organised activities around in the village, except the football club (beneath our social standing) and the tennis club (for wannabee socialites, people we didn't want to be associated with, which was mutual).

Such things are generally a bad idea.

What is a good idea is creating a library of commonly (in your context) used compound components that users can configure and use as required.

and place it in the proper package, and refactor the code to be more readable, properly indented, and using some more whitespace, and you should probably refactor out a lot of the code into separate classes.

Never seen a database where a where-clause on a string wasn't case sensitive.
If mySQL isn't, it's clearly not standards compliant (not surprising, I've known that for years) and a piece of rubbish (I've known that for years as well).

Use a real database engine like Firebird instead.

If it were true that we have a limited amount of memory then at some point we would have to stop learning. One could say "I have learned everything possible to learn, so I can go have a beer now.". I doubt that point in or evolution will ever happen, consequently we have infinite capacity to learn.

Uh, that point was reached in the 1800s when scientists were adamant that everything was known and all that needed to be done was write it all up.
They were of course proven wrong ;)

And an incapacity to ever fill something up doesn't mean its capacity is infinite. It just means the capacity is larger than will ever be needed. This may be effectively equivalent to infinity, but conceptually it's not.

better than the movie (in both cases).

yeah i know wtf do they have helmets ans shoulder pads when rugby players have a shirt and maybe a scrum hat

It's an American sport, the organisers are afraid to get sued by the players if they don't make darn sure noone gets any bruises when they walk into each other.
Pussies...

he explained it.
You either use a variable or method that you forgot to declare or you made an error in the declaration.
The latter can typically be a typo or a scope error (declaring it somewhere where it's not visible from the place you're calling it).

We rolled hoops with sticks and we were lucky to have them. Previous generations only had rocks and those were very difficult to roll with sticks.

lucky you! We only had sticks. Living in a forest we had lots of sticks but not much else (unless it rained, then we had mud).

kids played outdoors in almost all weather, indoors with legos and boardgames when it rained.

I dug a cave under a fallen tree in the forest, my alternative to a treehouse.
Surprisingly comfortable in all weather, I even installed plastic lining on the walls to keep moisture out.

And books of course.

What year was it when you were 14 though?

I am a child of the 90s so i grew up on DOS/3.x/NT/9x

I'm a child of the 1980s. When you could (if there was a supplier in your country) get an IBM PC-XT at 4.77MHz, 384KB RAM, and 2 128KB 5.25" floppy drives for the small sum of about $10.000 plus taxes (another several thousand for the 7" monochrome screen).

reduce your requirements, be less picky about where you send your resume, don't lie about your skills (decent recruiters and interviewers notice that instantly).

Java has excellent IDEs. IntelliJ is second to none, far superior to MSVS (and a lot cheaper too).
Eclipse and JBuilder aren't bad either.
Netbeans indeed is a disaster.

>> There's nothing special in Java that doesn't exist in C++
>Security as a language feature.
Networking as a language feature.
Multithreading as a language feature.
Standardised user interface libraries as a language feature (less useful for games as those generally don't use regular user interface elements).

Java was never conceived for making games, but it's quite capable if used by people who know what they're doing.
The main reason there's not been major adoption in the game industry is the incredible resistance to change in that industry, an industry where many still work in raw assembler or C because they consider C++ "too slow" (or too cumbersome, too modern, and a variety of other non-reasons).
Java is over a decade younger than C++, and is only now gaining acceptance.

There are several game engines (including complete 3D engines) for Java out there, and far more serverside code for game servers that use C++ (for example) client applications on a Java backend.

http://www.jmonkeyengine.com/ is a good example. I've not used it but it certainly looks powerful.

There is no magic bullet here.
You're not going to somehow create records in one database when they appear in another without some work on your end.

The normal way to do such things is to have a program run at regular intervals (once an hour, once a day, whatever) that checks for changes in one database and if it finds any does something in the other.

Conceivably you could also have the inserts in the master database trigger a stored procedure that launches an external program that in turn updates the other database.

same everywhere. But where there are a few honest lawyers, there are no honest politicians.

I like puppies better than pussies...

in the fridge, waiting to be cooked to perfection and served as dinner tomorrow ;)

because political pressure groups have effectively halted all development decades ago.

The state of engineering in the nuclear power industry is now what it could have been 20 years ago had there not been largescale political opposition to nuclear energy, fueled by disinformation campaigns by "environmentalists" and "peace groups" who equate nuclear power stations with nuclear weapons and present each of them as a disaster waiting to happen (falsely making people believe that what happened in Chernobyl is the norm and will happen to every nuclear powerplant sooner rather than later).

These disinformation campaigns have halted all development of smaller, cheaper, nuclear power stations and stations that can use the waste of regular plants as their fuel.
They've also succeeded in creating laws that prevent the refining of nuclear waste into fuel for power stations, which would reduce the amount of waste that needs longterm storage to a mere fraction of what's being stored now.
The activists don't want that to happen as it would void all their arguments about the dangers of nuclear waste.

I don't know Dave, I don't find it interesting either.
Only thing it's good for is upsetting the fans by making snide remarks about the failure of their favourite teams ;)

You forgot a group: lawyers.
They're almost as bad as politicians (all politicians are dishonest, only most lawyers).

when I was 14 we didn't have a computer, let alone a modem or internet access...

How times have changed, that even kids operate websites ;)

even worse, it would have been banned in at least one city had not an alert council member done a bit of research before voting...

nor is it the place of any program to assume it can control what appears in the console window.
The console is shared between everything running in the command shell that created that console, not just by any one program.

I think that if someone decides that they want to start using a substance like pot then it should be their own choice as long as it does not affect other people also as long as other people don"t have to pay for their choices when they become ill as a result of the substance

Problem is it inevitably does affect other people.
Their productivity at work goes down, leading to loss of revenue and/or increased workload for colleagues.
Eventually they end up getting fired and drawing social security, another drain on society (this time through them using up tax revenue).
Social security won't cover the cost of their addiction so they resort to crime. This directly affects their victims who end up traumatised or dead, and indirectly affects all of society through the depletion of police and justice resources and increase in their funding (out of tax revenue) needed which leads to tax increases or reduced government services elsewhere.
They end up in hospital uninsured or underinsured, again at the expense of others (taxpayers or people who do pay their insurance premiums).
In the end they may end up in a police morgue, again taking up time and resources of the police and justice system.

the best learning tool is a teacher who knows what he's talking about and a good book.

All those fancy "tools" you're talking about only lead to your students learning those tools instead of programming.

you need to add the current directory to the classpath as well.
It's not there by default on most modern operating systems for security reasons.

learning about such things would be a good start.
Learning how to ask questions that are not vague and ambiguous also helps a lot.

ask Dell...

depends on which registrar you choose and which TLD you want.
Some registrars can do it in near realtime for some TLDs, some may require manual checking of contact information and stuff, some TLDs require all kinds of paperwork to be sent in (signed forms, sometimes birth certificates or chamber of commerce registration forms, etc.) which can take days or weeks.

The US doesn't say who can have nuclear weapons and who can't, but they are actively doing the UN's job of policing the non-proliferation treaty (which is really the UN's job, but they don't do it for political reasons).
PS that wikipedia article isn't complete. They don't mention the abandoned Brazilian and Argentine projects for example (though those were stopped before producing a weapon, at least one of them probably has the capability to produce them if they want to, similar to Japan which would have them if their constitution didn't prevent it).

But let's get back to nuclear energy, which is what this discussion is all about.
It's safe (when using modern reactors, I'm not talking about the 1950s design graphite reactors like the one in Chernobyl and other places in Soviet satellite states), clean (if done properly, the waste can be used as fuel in other reactors), and relatively cheap (compared to other sources that don't use oil, coal, or gas).

the active ingredients of marihuana, like the active ingredients of heroine, can be used as painkillers under controlled conditions.
As they're both addictive, they should not be available except under medical supervision.

In fact the active ingredient of heroine is already so available, it's called morphine.
The availability of morphine under controlled conditions doesn't mean that heroine should be available freely...
I've seen the results of morphine addiction at close range several times (both my parents had it more than once after serious surgery), and it ain't pretty.
And that's the clean, refined, stuff, without the mirriad poluting substances that ravage the body and leave the user a physical wreck that make up heroine.

If you need software to know which of your pupils are cheating you may need to get more involved with teaching them.
If you're paying attention as a teacher to what your pupils are doing you're going to know in advance which of them are going to cheat, simply because you will have a pretty good indication in advance as to which of them will get which grade based on classroom performance.

start with learning English.

were I that teacher I'd have written those answers on that desk myself (of course deliberately making them the wrong ones) in order to catch cheaters.

But I'm sneaky :)

yup. And you seriously think Bush would have been able to plan and put into operation that super duper secret CIA spy operation on the US population in a single month?

No, it was started by Billy "blow me some more Monica" The Kid Clintoon, put into operation by people appointed by him, and never cancelled.
In fact it wasn't until those Clintoon appointees were replaced by Bush appointees that the operation became known to the outside world.

And I find it rather interesting that anyone who doesn't like Clintoon "hates America" while your irrate hatred of Bush is apparently quite nationalistic and shows your great love for the country.

But then that's the general attitude of leftists all over the world. Anything they don't agree with is "hatred", "inflamatory", "should be banned" even while they're constantly degrading others and taking away their freedom.

simple history kids... Before nuclear weapons there was a major armed conflict involving the superpowers of the time every generation.
With nuclear weapons there hasn't been such a major conflict for several generations.

Nuclear weapons in the hands of a potential adversary make you think twice about starting a war which may involve them directly.
Had there been no nuclear weapons the Soviets would for example not have stopped their advance west in WW2. That's blatantly clear. They'd have continued west, engaging US and British forces in combat, to conquer all of Europe.
They'd also have invaded China and Japan, taking on seriously weakened US and Chinese forces there after those had defeated the Japanese imperial military.

The JVM can actually mean that your Java bytecode will run more highly optimised than any native compiled C or C++ code can.
The JIT compiler can provide runtime code optimisation which in a native compiled language is impossible.
As a result it can provide far more tuning of the machine instructions to the exact specs of the computer it is running on than is possible with a native compiled language.

The main area where code running inside a VM is slower (if the VM is good, and the JVMs provided by Sun and some others are very good) is in the loading time of the executable code, as that has to include final compilation into machine code which native compiled code doesn't need.
When finally executing, it will often run as fast as or faster than that native code.

This is shown time and again when doing realistic comparison between Java and native code.
If the application is shortlived, native code is faster (in extreme cases completing before the JVM has completed loading). For longlived applications though the Java code will execute at least as fast as comparable C++ code (if both are written to the same quality standards, rather than as is often the case with "tests" setting out to show that "Java is slow" the C++ code being highly optimised and the Java code deliberately poorly constructed).

And oh, Java is NOT an interpreted language.
It used to be, …

ask Dell...

Wrong attitude.
You decide you want to become a software developer, and try to find employment in the field.
Afterwards you may try to steer your career towards specific subfields (like game development) by attempting to get jobs in companies where you can develop skills relevant to that subfield (and maybe even companies in that subfield).

But if you have no practical experience and limited knowhow, you basically have to take whatever job you can get.

uh, what exactly are you trying to achieve?
Or don't you know yourself?

no, we're not going to do you homework for you.
And it's definitely NOT urgent for us.
Your suggesting that it is is extremely rude and together with the rest of your attitude which indicates a severe case of laziness makes us disinclined to do anything to help you.

Not that we'd need to do anything more for you, as you've already been told where to find what information you need, help you either decided to ignore or failed to note because you didn't bother to read previous responses.

And remember that Python lists are NOT arrays.
Lists in Java also can be easily sorted (if there's an ordering defined for the content of course).

read yesterday that the leftists are now blaming Bush for the Kennedy assassination.
Never mind that he was just a rookie ANG pilot at the time.

personally I like the standard LAF of Tiger. Going to try JGoodies too some day soon.

System.exit(1) indicates abnormal program termination (crash, error).
Normal termination is indicated by exit code 0.

Java isn't designed for accessing lowlevel operating system functions like that.
You may be able to using JNI to call the required operating system functions for the operating system you have in mind, but it's better to use C (for example) for things like that.

i want to create same invirement on client machine and my client dont have java installed,
i dont want to say my client to installed java.i want to send java wih my application and when my client install my application neccessary files should be install at that time.
what should i do for that

If you want to duplicate your environment they'll have to install a JRE.
They'll have to do that anyway, it's as simple as that.

There are some programs that can be used to create an executable launcher which launches a JRE with the classes needed, but that rather defeats the purpose of a platform agnostic language like Java.
Unless you're writing a big commercial product that's only ever going to be installed on one operating system by people who can't install a JRE themselves there's no reason to bother.
Anyway, those things install a JRE as well, only it's embedded in the application.

Just ship a JRE installer with your application, and/or point your users to http://java.com to install their own.
It's painless. Most of them will have a JRE installed anyway, probably without knowing it, as most computers these days ship with one. It may not be the right version of course.
