Is it safe to use equals on BC entities?

Hello,
I have an entity with two accessors to another entity. I need to check whether both accessors "point" to the same entity. Is it safe to use:
// in employee entity
if (getDept1().equals(getDept2()) {
}Will accessors always point to the same entity instance when the corresponding db table row's foreign keys pair point to the same row in master table?

Apple encourages you to disable java (not javascript) on OS X Leopard because it's currently causing problems with websites which exploit that bug the outdated java versions have, to control your computer, that is a trojan.
It isn't an updated java version for 10.5. I have got the same problem so I am thinking in buying a 10.6 OS X version which currently has an updated security 'patch' for java.

It hasn't been safe for a long time, but one can argue that it's safer.
The US Dept of Homeland Security is still not completely satisfied. Their current guidelines are @ http://www.kb.cert.org/vuls/id/625617 and say, in part:
Oracle Security Alert CVE-2013-0422 states that Java 7 Update 11 addresses this (CVE-2013-0422) and an equally severe, but distinct vulnerability (CVE-2012-3174). Immunity has indicated that only the reflection vulnerability has been fixed and that the JMX MBean vulnerability remains. Java 7u11 sets the default Java security settings to "High" so that users will be prompted before running unsigned or self-signed Java applets.
Unless it is absolutely necessary to run Java in web browsers, disable it as described below, even after updating to 7u11. This will help mitigate other Java vulnerabilities that may be discovered in the future.

Is OnyX safe to use?

I've had some kernel panic problems and now have an Open With contextual menu problem as noted in my previous submission here. It was suggested that I use a utility called OnyX which cleans caches among other things.
Does anyone have any experience with OnyX and any warnings?
Steven

Actually I wouldn't go as far as to say Onyx is safe to use. It is not a maintenance utility despite others calling it, Cocktail, Macaroni, Applejack, Jaguar-Tiger Cache Cleaners, and other multifunction utilities that do more than one task. The only safe utility to use is a backup utility. Everything else should be treated as an after backup utility used only, and I repeat only for troubleshooting, when you know what it is you are troubleshooting, and are ready to restore the backup if the troubleshooting doesn't save you time. If you don't have a backup, some troubleshooting utilities can actually dig you a deeper hole, whereby data recovery is the only way to restore your situation with expensive data recovery companies. Moral of the story, backup first, worry about alternate utilities later. My backup FAQ* goes into detail on that:
http://www.macmaps.com/backup.html
The real danger with many of the other utilities which specifically empty system caches is that caches can get corrupt, sometimes requiring a complete erase and install to resolve a persistently corrupting cache file. The real danger of prebinding utilities is you can render your Mac unbootable:
http://www.unsanity.org/archives/macos_x/shock_andawe.php
Permissions sometimes is not repaired properly by these utilities, unless you use Disk Utility of the boot drive. Though thankfully with Tiger and newer at least you can use the installer disc's disk utility on a newer version of the operating system than is on the installer DVD. Previous versions of the operating system were not as generous, and required you have an equal or greater version of Disk Utility to do repair permissions.
Whoever recommended Onyx did so only because they were lucky or knew what they were doing, and assumed you would too. These swiss army knife utilities need to be guarded with care, and only to be used when you have a backup on standby.

ITunes 11.1.3.8, safe to use?

Is iTunes 11.1.3.8 safe to use with Windows 7 and an iPod Classic?
I am currently at 11.1.1.1 (and held off on that until they fixed the podcast issues) since I remember there were alot of problems with some devices no longer being recognized to sync, but I think that was mainly Win 8 or 8.1?

Works fine for me.

Spilled water on MacBook Air - safe to use after a week?

Last Friday I spilled a glass of water all over my MacBook Air's keyboard. I jumped up, tipped the laptop over to get as much water off as possible, and dried off the outside. I took it in to Apple immediately and was told it needed so many repairs, that it would cost more than the laptop itself. The guy who looked at my Air was able to turn it on, but the monitor was flickering and had horizontal lines. He took it apart and said the motherboard was fine, but I would need a new logic board, speakers, screen, etc. and said I should be able to get my files off onto an external hard drive. Since it was such a costly repair that I couldn't go for, I didn't get a list of everything that had to be replaced.
When I got it home, I wasn't able to power it on like he could. I let it sit on my dresser all week, open and upside down, to let it dry and allow any extra water to drip out the front. Tired of looking at it, tonight I decided to try one more time and turn it on, and it did! I was able to email myself some important files that I thought I would never see again, so programs and internet worked. The monitor seemed completely fine, the brightness goes up and down normally, the speakers work, and I didn't notice any problems with the keyboard.
It seems to be completely fine, but I'm a bit worried about whether or not it's safe to use, and if there's anything I should be looking out for. At the Apple store I was told that it needed so much, but maybe it's fine for now? If I am able to use it, should I be thinking about replacing it anyway? I'll be wanting to use it next fall for school. Sorry for the huge wall of text, I thought it would be best to know as much as possible.
Thanks.

That's great news. I'm not a computer guy but I am very experienced in automotive. The way I see it is even when you took it in and they cleaned it there is no way to get all the water out if it's really bad. The water will cause shorts and all kind of thing will malfunction. Now that the water is dried I would take it in and get it retested. You see, the first test they did on it was not accurate because of the water (causing it to short). Now you can get a good test. Who knows, it might be just fine. I remember drying cars for weeks at a time. One thing to have them look for is any corrosion that might had formed. My guess (only a guess) is that if it's working good now you got really lucky and it will be fine.

Boot Camp safe to use with Time Machine?

Is Boot Camp safe to use with Time Machine? I will be installing Windows on a partition and using an external hard drive to back up. I only want the Mac partition to be backed up, though, since Windows will just be used for applications which I can reinstall if my machine messes up.

Yes, this is perfectly safe. Time Machine won't backup the Bootcamp Windows partition.

Is it safe to use an 85watt adapter from a 2006, 17" macbook pro on a late 2011 15" macbook pro?

Hi. My question is pretty much as the heading says :
Is it safe to use an 85watt adapter from a 2006, 17" macbook pro on a late 2011 15" macbook pro?
As far as I can tell from googling and searching around, it does appear that it is safe to do so.
Specifically this page
http://support.apple.com/kb/HT2346
But I just wanted to double-check for confirmation that it is indeed safe to use the adapter from such an old mbook pro in a newer one.
The wattage is the same.
I wish to do so as I prefer the T-connector, and my older adapter has a much longer extension cord on it.
If not I may order another one from ebay.
Any idea how to check that an adapter from ebay is a true / legitimate / authentic apple adapter?
Thanks for your help.

Yes.
I recommend you buy one directly from Apple. There are many counterfeit power adapters on the market that could damage your MacBook Pro or potentially cause a fire.

Nearly all of them are, even if the seller insists it is "genuine OEM". Legitimate adapters from eBay are likely to be used, not new. There is nothing wrong with used, as long as you know what you're getting.
Identifying a counterfeit is possible only through close examination.

Is it safe to use the MBP in closed clamshell mode?

I've connected my MBP to my LCD TV and started to use it as my desktop.
I'm deactivating the main display of the MBP by putting it into sleep mode and moving my mouse, so it wakes the computer up and shows image only in the TV, keeping the main display turned off.
I'm constantly monitoring the temperatures of the MBP with iStat Menus. It seems that the temperature is always the same, no matter if the main display lid is open or closed.
So, based on these 2 articles:
http://support.apple.com/kb/HT3131
http://support.apple.com/kb/HT1778
Is it really safe to use the MBP with the display lid closed?
If I decide to run a heavy load application (like a game) and the MBP starts to get warm, would it damage the display, because it is too close to the body of the MBP?

Yes it's perfectly safe and designed to be used that way, 90% of the time this one's used in a similar configuration. The only time the fans come on 100% is when I watch Flash-based items from YouTube or similar. I've never run it for any extended length of time with the fans at maximum I must admit but as long as the air flow is good there shouldn't be any problem.

My 17" Macbook Pro battery swelled up and kind of exploded. The apple genuis said it is still safe to use, that doesn't sound right.

I am just kind of worried that it doesn't even fit. Do I need to kind of pop the expanded portion of the battery to get it to fit back in? The case of the battery has come apart and so to fit it back in I would have to press it back together. The battery is low count and had great capacity when it happened. I don't want to have to buy another one when this one is fairly new.

... The apple genuis said it is still safe to use, that doesn't sound right.
I agree with you, that's not right.
This may seem to be a little problem - fix it before it becomes a big one.

This is very hard to read
insert standard rant about mixing ugly scriptlet code into a JSP like this.
Recommend the use of JSTL to reduce scriptlet code.
Also comment on how SQL should never be in a JSP, but rather be in a bean somewhere.
Particularly if it is a static list, that doesn't depend on any parameters.
And why call rs.getString("Type1") four seperate times? Call it once and reuse the variable.
I can't see the reason for that first if statement, as it does the same thing on either branch of the if.
Also, you have an extra rs.next() that you might not need.
[ end rants]
Oh - your null pointer exception.
It could be coming from several places:
Most likely is request.getParameter("List_Type").equals...
If the parameter List_Type is not present, then it will fail.
Also you have request.getParameter("Type1")=="")
that should be
if (request.getParameter("Type1")==null || request.getParameter("Type1".equals("")

Is it safe to use macpaw on your mac?

Hi, I was looking to clean out my mac because I have not done so in awhile. What is safest to download and install to clean out my mac? I have two sites that I have looked into but I don't know if it is safe or recommended by Apple. I've looked at MacPaw and MacUpdate, are these safe to use on my computer? Help needed.

These are third-party applications. Apple does not make recommendations of third-party software. If you don't know what they are nor wish to take the time to find out, then the safest thing to do is remove them:
Uninstalling Software: The Basics
Most OS X applications are completely self-contained "packages" that can be uninstalled by simply dragging the application to the Trash. Applications may create preference files that are stored in the /Home/Library/Preferences/ folder. Although they do nothing once you delete the associated application, they do take up some disk space. If you want you can look for them in the above location and delete them, too.
Some applications may install an uninstaller program that can be used to remove the application. In some cases the uninstaller may be part of the application's installer, and is invoked by clicking on a Customize button that will appear during the install process.
Some applications may install components in the /Home/Library/Applications Support/ folder. You can also check there to see if the application has created a folder. You can also delete the folder that's in the Applications Support folder. Again, they don't do anything but take up disk space once the application is trashed.
Some applications may install a startupitem or a Log In item. Startupitems are usually installed in the /Library/StartupItems/ folder and less often in the /Home/Library/StartupItems/ folder. Log In Items are set in the Accounts preferences. Open System Preferences, click on the Accounts icon, then click on the LogIn Items tab. Locate the item in the list for the application you want to remove and click on the "-" button to delete it from the list.
Some software use startup daemons or agents that are a new feature of the OS. Look for them in /Library/LaunchAgents/ and /Library/LaunchDaemons/ or in /Home/Library/LaunchAgents/.
If an application installs any other files the best way to track them down is to do a Finder search using the application name or the developer name as the search term. Unfortunately Spotlight will not look in certain folders by default. You can modify Spotlight's behavior or use a third-party search utility, EasyFind 4.9, instead.
Some applications install a receipt in the /Library/Receipts/ folder. Usually with the same name as the program or the developer. The item generally has a ".pkg" extension. Be sure you also delete this item as some programs use it to determine if it's already installed.
There are many utilities that can uninstall applications. Here is a selection:
AppZapper 2.0.1
AppDelete 3.2.6
Automaton 1.50
Hazel
AppCleaner 2.1.0
CleanApp
iTrash 1.8.2
Amnesia
Uninstaller 1.15.1
Spring Cleaning 11.0.1
Look for them at VersionTracker or MacUpdate.
For more information visit The XLab FAQs and read the FAQ on removing software.

Is it safe to use the power adapter without the grounding pin?

Is it safe to use the power adapter without the grounding pin?
Last time I unplugged my power adapter the grounding pin stayed in the wall socket. Is it safe to use it with just the 2 prongs?

Is it safe to use the power adapter without the grounding pin?
No. If a short circuit occurs, it may cause the case of the computer or other device to build up an electric charge. The grounding pin absorbs any charges generated this way; without it, someone touching the device may get shocked.
