I'd like to disable Java but I work at a school district where...
*why* do you want to disable Java? Just on general principle? I would've thought that mac users would be biased in favor of vendor neutrality.
Not exactly true. It would be one thing if people hijacked a board and advertised their services with some sort of code words. Quite another to actually dedicate a special place for them to transact business with the disclaimer "uh, dont do what this board is named if it is illegal"
Which was why that board exists in the first place -- those ads were previously on other boards.
I realize this is a private business, but I find it odd there's such a commotion about removing their adult services section but they think nothing of disallowing gun listings. Looks like a double standard to me.
Craigslist only created that category because users were complaining about erotic ads infesting general areas -- the point was to segragate the ads. Now, those ads will continue, you'll see erotic ads in general sections. Guns? There isn't quite the demand for guns as there is for sex, plus you can buy guns legally.
Languages aren't fast -- compilers are efficient. How "fast" a language is perceived to be is purely a function of whether an efficient compiler exists for the particular platform.
Plus, you can always compile Java to native code.
One example is generics: if you use ArrayList<int> in Java, you end up with a bunch of boxing/unboxing overhead at runtime, because the compiler erases the type and turns it into a list of objects. List<int> in
While C# is better in some regards, I don't think your description of Java is quite correct. AFAIK the boxing/unboxing occur at compile (to bytecode) time and the JVM sees *exactly* the same code as if you'd done List int -- that is, generics is strictly a syntactic sugar in Java which can only be detected at compile time. Absolutely, it's time for Java to die and rise from the ashes as Java2, or just die completely and let JRuby/scala/whatever take over. Sure, c# is a tad better in some regards, but what's the point of a VM which isn't cross platform?
You hit it in one. IF your company runs Oracle on Red Hat, prepare to get fucked.
If your company decided to run Oracle on RedHat you're already fucked.
What's wrong with Oracle on Redhat?
The exception might be if the uber-fast solution enables a fundamentally different approach to computing than nominally available. Maybe Oracle isn't planning so much on selling these solutions to end-users, as they are in building out a giant server cluster that they lease out a-la other so-called "cloud" computing solutions. I.e. they don't sell you sparc+oracle, they sell hosted ERP, etc. Building the servers themselves, they may be able to argue their infrastructure costs are lower than for vendors like Amazon who have to buy their servers from others.
Still, while that might buy them a little time, there's nothing preventing the creation of open hosted services. Vendor lock-in is vendor lock-in, cloud or not.
In the above situation, there's no hardware lock-in, just to the API for that cloud. For example, assume Java and Oracle for the db. Where's the lock-in, exactly? Strictly to the db, it's not prohibitive to go with Java + mySql (or whatever) if you decide it's not worth it. Notably, google app engine, which does something like the above, has its oddities, but they're relatively minor. If Oracle believes a vertical monopoly will yield greater profits for them, and greater savings for their customers, then more power to them. I'm not so convinced it would work out, just because of hardware commoditization, but I'd be interested to at least see the attempt.
".. it was widely assumed that Oracle was interested only in Sun's software technology
Java is open source, so there's not much reason to buy it. What other Sun software technology would Oracle want?
The JVM distribution earns money for Sun.
this is so weird. talking gold investing on slashdot? i like gold but this mainstream attention is driving me crazy - there is a bubble in every market and i can't figure out how much time in this gold bull run we have.
Gold is, I dunno the technical term, but I think a "hedge" investment. In times of war or depression gold goes up. Inversely, if the cost of gold decreases that's a marker that things are looking up otherwise.
I don't see how Google would be a better steward of Java than Oracle. Google seem content to define their own pseudo-Java platforms such as Android (forked from Harmony, not fully Java SE/ME compatible) and AppEngine (not supporting full Java EE) than cooperating with other parties through JCP.
I wonder to what extent Google is simply being pragmatic, creating something which works for them, versus hijacking Java to create GoogleJava.
They had started to play nice with EJB3 and TopLink, but now they have absolutely no reason to keep doing so. They now have much more weight in the JCP process (if the JCP even continues to exist) and they can now push out better ideas from competitors. I'm very apprehensive about the future of Java.
The best thing would be for Java itself to move towards being frozen and to start over. Not that there's any need for the JVM to go away, but it's time to acknowledge that Java has some inherent flaws which cannot be tweaked away.
Ummm, even Sun says you should not be launching threads inside of JEE containers.
I've never heard that. Why? You might want to make an operation run in the background, so give it a different thread.
great, so first google totally rips of linux and calls it 'android' and now its ripping off java.
"Android is a software platform and operating system for mobile devices, based on the Linux kernel, developed by Google and later the Open Handset Alliance.[2] It allows developers to write managed code in the Java language, controlling the device via Google-developed Java libraries.[3]" http://en.wikipedia.org/wiki/Android_(operating_system) No, I don't think that Google ever ripped off Linux, nor do I see that they're ripping off Java. Besides, they're both GPL'd, so there's not much "ripping off" to do, since any code changes make their upstream, or result in an essentially public fork.
Java hasn't taken over the world like it was meant to. The position it could have held unfortunately is slowly being eroded away by
Which is a shame. There's still hope for Java, but not directly, I think. The hope is for things like JRuby, JPython, etc. Maybe it's time to let Java die, as in start freezing it and re-allocate resources elsewhere -- anywhere but
Sun's revenue is close to $14 Billion a year. To compare, RedHat is only $164 Million, Novel is $214 mil, Oracle is $5.5 billion, IBM is $127 Billion.
They're selling stuff and bringing in a decent chunk of change. The problem they have is in making a profit. There's a huge potential there.
If there revenue is that great, then they just need to reduce costs to get to profitability. However, those numbers just don't make sense.
In any formula, constants (especially those obtained from handbooks) are to be treated as variables.
