Which method signature is the best?

Among the following method signatures in Java, which one can provide the best performance while the method is called? Why?
(1) public void my_method( String a, int b, int c )
(2) public void my_method( int b, String a, int c )
(3) public void my_method( int b, int c, String a )

1) All primitive types (except long and double) are pushed onto the stack as 32-bit entities and are 32-bit aligned. The reference types are pushed as a reference and occupy 32-bit also.
2) If the method have had tens or hundreds of parameters, the opcodes for accessing some parameters will have short offsets and other parameters will have long offsets. When you have only 3 or 4 parameters there is no difference between the offsets needed to access each parameter. The difference of time used for the interpreter or JIT compiler for dealing with short or long offsets usually is negligible.
3) So the better way to speed up your program is to forget micro-optimization and concentrate in better algorithms and caching data if possible.

Which KVM switch is the best for Mac Mini

Base on individual experience, which KVM switch is the best for Mac Mini

Hot-Key mode MacMini and IO Gear KVM Switch MiniView Micro USB Plus
Fusionwolf, can you help me?
I want to use my TFT monitor (HPvs19 ) with a MacMini and a Casablanca KRON PC. The monitor works good with both computers, when connecting them separately.
I've bought a KVM switch MiniView Micro USB Plus (IOGear GCS632U) connected it as written in the IOGear Installation Manual. Now I can use the monitor with my MacMini and my Mac keyboard, but I cannot switch to the PC.
In the IO Gear manual several methods to switch ports are written. But every method starts by invoking HotKey mode.
The manual reads :
"To invoke HotKey mode, do the following:
1. Press and hold down the NumLock key
2. Press and release the minus- key
3. Release the NumLock key"
and
"When HotKey mode is active, the Caps Lock, and Scroll Lock LEDs flash in succession to indicate that Hotkey mode is in effect."
I've tried many times to do this pressing/releasing on my Mac keyboard. Within different time/speeds. But with no result... I CANNOT get in the HotKey mode...
What can I do? Are there other ways to get in HotKey mode with my Mac keyboard (bought with my previous iMac some 4 years ago)? Or are there other ways of switching with the IO Gear KVM Switch?
Thanks a lot in advance for an answer!

I am thinking of getting my first Macbook pro for uni and was just wondering which one would be the best? The macbook pro or macbook pro with retina display? or even wait for the new release in 2013 ?

I am thinking of getting my first Macbook pro for uni and was just wondering which one would be the best? The macbook pro or macbook pro with retina display? or even wait for the new release in 2013 ?

If your budget is unlimited, look at both the retina and non-retina and make a decision based on your preferences. If funds are tight, explore the options in the refurbished section. Unless you are dealing with courses that demand specific performance parameters, any one of these options will suffice.

Hi, I planned to purchase a laptop for me to use for graphic design ..could let me know which laptop would be the best for me to use ? Thank you!

Someday - and no one knows when that day will come - maybe all applications will be able to take advantage of the Retina display. But for the present, not many do: including all Adobe applications. There was a demo of Photoshop at the Apple World Wide Developers Conference of Photoshop running at native Retina resolutions but no one at Adobe in marketing is saying when, if or how the upgrade may be coming. It could be a week, it could be a year, it could be 2-3 years. No one knows. And only Apple app's (for the main part) are really utilizing the native Retina display.
I've seen some demos of some applications (Apple's) that take advantage of the Retina display and they're awesome. But in actually working in the here-and-now I've heard quite a few gripes, particularly on the Photoshop forum, of menus looking pixelated and/or 'blurry' so I'm not quite ready to jump into the Retina display boat just now. Don't get me wrong - others have ad are very, very pleased with their selection. But until Retina displays are available on larger monitors, the maximum work area that you're going to be able to use is 15" - and that's simply not enough room for full-blown graphic design. Then there's the cost factor - for the $4,000+ you spend for a completely full-blown Retina kit, you can get a standard MacBook Pro, 16 GB of RAM, a fast SSD and even the Apple Thunderbolt Display for the same amount.
The standard MacBook Pro isn't better than the Retina display: it's just different. And I think (and this is only my opinion - other graphic designers should feel free to jump in here) that it's the best computer that you can get for your specific purposes. And, towards that goal, I have to recommend a very good external monitor (there's nothing more annoying than having to use InDesign in a single-page mode rather than side-by-side because your monitor isn't big enough).
Remember that this is only my opinion and that others might jump in with their own. But I was in the electronic pre-press business for more years than I care to admit and we always - always - worked with at least 19" monitors (and that's back when dinosaurs actually ruled the world).
I hope that others will jump in with their comments. I'm going to follow this thread and see!
Good luck,
Clinton

Which hard drive is the best?

I was thinking about replacing the hard drive and the combo drive with something better.
Which hard drive is the best? Is it the Western Digital? I was also looking at Samsung but after reading about them using harmful chemicals, I became a bit hesitant.

Which web browser is the best?(firefox, chrome, safari)

I am using mac 10.6.4 which web browser is the best for mac?
Facebook, youtube etc.
Thanks
Ala.

What could be possibly better than an Apple product for an Apple product.
Actually there are various areas where Safari is defective compared to other browsers. For example it lacks the ability to override the fonts of a website with fonts of your own choosing. Also it cannot send a different language identifier for multilingual webpages without changing the language for the entire OS. Whether the defects matter depends of course on each user's individual requirements.

Toshiba Recovery method - Which set up is the best

I have purchased a new lap top and on set up it is asking me to select a recovery method. Options are
- Recover to out- of -box-state (System Recovery Options are included)
- Recover without changing the hard drive partitions
- Recover to a custom size partition
Which is the best option to select?
I am thinking that the custom would be the best once I have made my recovery discs after full set up but want to be sure.
Can anyone help?
Thanks smilee

Hi
- *Recover to out-of-box-state (System Recovery Options are included)*
This Option sets your notebook back, to the Factory default status. The partitions will be deleted and created again, as they have been on the first boot.
Note: All data will be lost and HDD Recovery Option will still be available, if you want to recover your notebook again.
- *Recover without changing the hard drive partitions*
All data on the first partition will be lost and HDD Recovery Option will be still available, if you want to recover your notebook again.
- *Recover to a custom size partition*
All data on the HDD will be lost and HDD Recovery Option will not be available anymore, if you want to recover your notebook again. Be sure to have a recovery DVD created for the future

Looking for an app for a blue tooth, type I want to use on my Iphone is a "jawbone" Question is out of the many available in the store which one would be the best and most reliable?

Looking for an app for blue tooth on my Iphone. Out of the many in the app store which one(s) would be the best & most reliable? Currently trying to set up for an older Jaw Bone?

You are asking several different questions. If you need to store your photos, music, and movies on an external volume, you certainly can. Any externally connected hard disk drive will work, connected either directly to your Mac or to your Time Capsule as a shared volume.
You should not rely upon using that as a backup device though. Although you certainly may use it for both purposes, it is a better idea to have dedicated backup devices for a variety of reasons not limited to redundancy. You would not want to simultaneously lose all your pictures as well as your backup. If they are all on the same device, that could happen. Furthermore, a backup cannot back up the volume on which it is running.
As for adding an Extreme or Express, using its LAN port for your iMac, and then enable Internet sharing so you can effectively use the iMac as a "hotspot", you can do that too, but I am unclear on what benefit you believe this arrangement would convey for you.
An Extreme's Guest network is separate from its Main network; that is the reason for having it.

Which MacBook Pro is the best for me

Hello, I was looking to purchase a MacBook Pro but the thing is I don't know which one to get. It is between the
13-inch: 2.4GHz

2.4GHz dual-core Intel Core i5
Turbo Boost up to 2.9GHz
8GB 1600MHz memory
256GB PCIe-based flash storage1
Intel Iris Graphics
Built-in battery (9 hours)2
Or
15-inch: 2.0GHz
with Retina display
Specifications
2.0GHz quad-core Intel Core i7
Turbo Boost up to 3.2GHz
8GB 1600MHz memory
256GB PCIe-based flash storage1
Intel Iris Pro Graphics
Built-in battery (8 hours)2
The 2,600 is out of the question.
Which one should I get if I am
-Surfing the Internet
-Watching Netflix
-Doing School Work
-Editing and uploading videos
-Playing 1 or 2 Games.
Thanks if you can help me.
Tom L.

Go for the 15-inch MacBook Pro with Retina display. It has got a quad-core CPU and a better GPU, which will improve your video editing and games experience, even if the Intel Iris Pro GPU is not the best GPU for those tasks

Which method can get the computer screen photograph

besides the createscreencapture method of robot class,which method have the
function of grabing computer screen photograph.thank you.

Do you know and this is some sort of competition to name the other method and class? Or do you not know - in which case: why don't you want to use createScreenCapture()?
[Edit] I don't think there is a way that doesn't involve the Robot class.

Which method is better, the SELECT .. CURSOR(.. , or the Queries in loop

I have a table t1, this table has 1 to many relation with
tables t2,t3. t2,t3 do not have any direct relation with eachother.
I have to read all data in all tables, what do you prefer
from the following. I am using 10g release 2 but if there
is some better way in 11g I can go for it also.
Also generalize this for t2,t3,t4,t5,... etc.
Method 1.
FOR i in (SELECT * FROM T1) LOOP
FOR j in (SELECT * FROM t2 WHERE t2.x=t1.x)LOOP
...process data...
END LOOP
FOR k in (SELECT * FROM t3 WHERE t3.x=t1.x)LOOP
...process data...
END LOOP
END LOOP;
Method 2
FOR i in
(SELECT t1.*,
CURSOR(select * from t2 where t2.x=t1.x),
CURSOR(select * from t3 where t3.x=t1.x)
FROM t1) LOOP
... process data...
END LOOP
Which one will be the faster and why.
Thanks

Your question is meaningless.
Why? Because...
> There is no way to join all these 3 tables correctly, because joining will
produce reduandant rows.
and...
> its impossible to join all three tables here
and then you show Method 1 and 2 as options.
Guess what.
You have coded a nested loop join in both!
So just what makes your hack of a join in PL/SQL so much superior than an "impossible" nested loop join in SQL?
Your problem is not joining.. it is conceptual and design fundamentals. Your approach says that the problem should be approached by discarding the fundamental concept of joining data in a RDBMS.. and thinking of row-by-row slow-by-slow serialised processing.
Join. Use parallel processing. Either PQ or self-rolled via PL/SQL. There are loads of tools in the Oracle toolbox to address this type of problem.

Which Canon Camcorder has the best built in microphone for recording musical instruments

Which Canon Camcorder in the affordable price range has the best built in onboard microphone for recording musical instruments
Thanks.

TheBee,
Thanks for writing!
The built-in microphones on the camcorder are fairly similar. When you're recording music, we recommend the use of an external microphone.
The mic you use really depends on what you're recording and where.
So we may better assist you, please provide a bit of information regarding the type of recordings you'll be making, the music and the setting (i.e. what kind of venue, your distance to the music, etc).

Which compressor Type is the Best for Voice over recordings?

The compressor Plug in in sdtr pro has a vca, platinum, opto etc
Which One is the Best for male Voice overs?
I don't Know the differences opto, platinum, opto....

Opto, VCA, and FET refer to models of different analog circuitry that accomplishes compression in different ways.
Not positive, but I think "platinum" is not really a model, but the plug's own compression scheme.
When I worked at an audio post facility, we had hardware UA 1176 compressors, which are FET compressors. They sounded pretty fantastic, but that's not saying that the model in the plugin will sound that way.
Here's a nice discussion of the different types:
http://www.barryrudolph.com/mix/comp.html
Scroll down to the salmon background sidebar.
Ultimately, it's really best to try the different models out and see which sounds best on your material. Let your ears be the judge.
Good luck!
