"Actually I would say you're both right and you're both wrong."
Not if the definition of what an interpreted language is has changed since the last time I looked.
Java has however a very efficient preprocessor that makes it's run time interpreted source code (the byte code) very efficient;-)
I think the problem here is what one reads into "Interpreted". To some programmers this means a poorly typed macro language with bad performance and horrible memory efficiency. And Java is certainly none of that.
So you can distance Java from those wrong presumptions by not calling it an interpreted language (which is wrong), or you can call it for what it is and explain how Java differs, and how that gives it the advantages that interpreted languages have plus almost as good performance as compiled languages.
"Aiiighghghghhhhh!!!! Why, why, why do people keep saying this?! "
Because they are right, and you are wrong.
The definition of an interpreted language is that the code is converted to native machine code at runtime. Java is "compiled" into Java byte code. That is correct. But Java byte code is NOT native machine code. It is code that the Java Virtual machine *interprets* into native machine code *at runtime*. So yes, Java is an interpreted language!
"The Notes login screen contains a series of 4-5 icons that randomly swap places as you type your password. Why? For security. See, when a hacker is looking over your shoulder as you type your password they will become distracted by the changing pictures. No, seriously, that's what the Lotus clowns consider security."
It *is* a security feature, but you don't have a clue how it works you ignorant bastard. The symbols change for each character when you type in a password, and it stops at the same uniqe symbol when the last character is entered. The reason for this is that if someone installs a trojan "password phishing" app on a client appearing to be the Lotus Notes login prompt you cannot mimic that behaviour since you dont know which uniqe symbol that particular user will see (the algorithm is based on the encrypted password). This may be overkill in most situations but Notes/Domino is used both by FBI and CIA and in other organisations for top security applications.
"Notes is "VERY STABLE"? Then why is there an internal IBM tool called killnotes.exe? When Notes crashes you either (a) reboot your machine or (b) run killnotes to kill all of the Notes processes that refuse to die so you can restart the app."
Notes (the client) is not extremly stable. The Domino server however is a rock. It NEVER dies if properly set up. And that is what counts.
I work at a big corporation with hundreds of Notes/Domino apps. This platform has delviered tremedous business value to us for 10 yrs plus. Reading the all the dungpiles about Notes/Domino here on slashdot has made me firmly conviced that the open source community still don't have a clue about what business IT wants and likes. Thank you Slashdot. It was healthy to be reminded about that./Patrix
First of all, light and sound are *very* different phenomenons. Light is very weird, sometimes behaving like particles and sometimes like waves, depending on what you expect from the experiment. Einstien et al knows more about this.
However you analogy in this case is correct, but not your conclusion.
Soundwaves can also can be compared with ripples and waves on a liquid surface. If you throw a few small stones and big rocks into a swinning pool, the waves and ripples from the impacts will interfere with each other and bounce off of the walls and corners of the pool. This is comparable to the situation in a room with speakers. The big rocks are the bass speakers, and the small stones are mids and highs.
The smaller waves from the higs and mids ride "on top of" the bigger bass waves mostly unaffected. But charateristics in the room makes the big waves move irregular and sometimes "cancel" each other when bouncing in the corners. This affects the ripples riding on them and creates mostly "temporal" errors - A high or mid frequency sound does not reach your ears at the exact right time, which is crucial for the surround effect.
Because of this it is better to transform the sound signal as close as possible to the place where it should be in the virtual sound space, not letting the "chaotic" wave situation in the room affect it. And this in turn, concludes that more speakers are preferable.
This is all very theoretical, and in a normal living room 5.1 is plenty I would say. In larger rooms however many speakers can be critical to create a good virtual sound space.
If waves did not interfere with each other this way, two speakers would be enough to create perfect 360 dgr surround sound anywhere. This is known as "virtual surround" and works flawlessly in a echo free room. In a real room the problems mentioned above makes it less effective.

When will you engineers that code get this? Probably never because engineers only listen to themselves and occasionally other engineers.
Imagine you have two bridge building teams. Both the teams have this magic machine - If you enter the exact specifications of a bridge into the machine it will be built instantly! You can use the machine as many times as you like.
Now, imagine the first team worked like you traditionally do when you design and build a bridge, and only used the magic machine one time at the end of the project, when they where absolutley positively sure their bridge design was correct.
The other team uses the machine all the time. In the beginnig they have lots of errors in their bridge design, but as they build and test several new bridges their design improves.
Now, which team would you guess builds the best and cheapest bridge in the shortest timeframe?
This is where the analogy between bridge/house building and software design utterly fails. There is NO COST OR INCONVENIENCE in building software. Just click compile.
M$ are much more clever than that (-1 Flamebait)

Linux Kernel Personality FAQ For UnixWare 7
What is the Linux Kernel Personality?
The Linux Kernel Personality (LKP) is a feature of the UnixWare 7 operating system which enables the installation and the direct, native execution of Linux(R) applications. The primary attributes of LKP are:
Exploit the power and scalability of the UnixWare kernel to run Llinux applications. the Linux Kernel Personality contains most of the RPMs required to execute native Linus applications, but it does not include a Linux kernel.
Applications compatibility: Linux applications install and run without modification. UnixWare 7 customers now have a powerful tool to assist in the migration from Linux to UnixWare.
UnixWare 7 feature availability: Linux applications can benefit from the features and options available for UnixWare including a journaling file system, RAID support, and increased scalability, security and reliability.
Versatility: Users can dynamically choose either environment, Linux or UnixWare 7 or mix both, as needed.
Didn't SCO suspend its Linux product line?
Yes. The Linux products were suspended due to intellectual property issues associated with Linux. The LkP feature doesn't contain a Linux kernel, and therefore to the best of our knowledge, there should be no infringement issues. If the prior statement were proven inaccurate, SCO would take appropriate steps. In the meantime, the LKP feature is available to assist customer migration from Linux.
Why is The SCO Group(R) doing this?
SCO recognizes that many customers want to migrate away from Linux, but can't afford to disrupt their day to day operations, nor can they afford the engineering resources to port and test the Linux applications in a UnixWare environment. The Linux Kernel Personality addresses all of these concerns. Native Linux applications runs unchanged on UnixWare, which provides the following benefits to the customer:
Customers can asses using UnixWare in their environment without making costly application program changes.
Customers who want to migrate to UnixWare, but some of the source code for critical applications they need to continue to run is no longer available.
Customers are considering migration to UnixWare but are concerned about the risk of changing both the operating system and the application at the same time.
Does LKP emulate a Linux application environment, much like lxrun?
No, LKP is not a Linux environment emulator. An LKP installation includes the Linux application environment running on a UnixWare kernel. Unlike the LxRun environment, LKP doesn't contain an emulation layer.
How can I install Linux applications? Do I have all the tools?
Yes, you can install Linux applications. Linux libraries and system tools, including the rpm installer, the shell utilities, and the configuration files, are provided in UnixWare 7. The UnixWare 7 installation loads the entire (former) Caldera OpenLinux Server system, with the exception of the Linux kernel.
How is Linux compatibility provided?
LKP is a standard feature ofUnixWare 7. LKP and the necessary OpenLinux RPMs are part of the basic media kit.
Do I get a full Linux distribution with UnixWare 7?
LKP does not provide a Linux kernel. With the exception of the Linux kernel, however, the entire Linux distribution is installed in a/linux directory.
Is the use of Linux applications transparent?
Yes. Linux ELF binaries are treated as first class executable programs. The Linux process coexists with other UNIX processes and shares the system equally. You run with Linux shells and desktops and use familiar Linux tools and utilities. The system keeps track of your environment for you, so that Linux and UNIX functions and utilities do not collide.
How can I access the Linux environment from UnixWare 7?
>GPS-guided JDAMs dropped from a B2 at 20,000 >feet are the most precise weapons ever developed >in the history of warfare
No its not! A soilder with a rifle is.
The problem, as seen with Saddam and Bin Laden is not to kill or capture a target, but to find it. And even if you know or suspect the target is in a certain location theres is now way knowing they are still there when you drop the bomb. The only way to be sure is to have an observer on site at point blank and in direct communication with the bomb dropper, and that is risky.
And if you have to take the risk anyway, a sniper is more suitable. The collatareal damage factor(which means killing innocent men, whomen and children) is close to none and it's much much cheaper than a multi million $ plane with a multi millon $ bomb.
These weapons are not very effective, and are perhaps the perfect example of a technical solution to a non technical problem.
