Should I not be using a keyboard cover?

I got a keyboard cover yesterday and I love it already, but I've heard quite a few people say that it can, and for them, has, damaged the screen. I'm just starting college so I'm not exactly made of money, and I'd hate to ruin my screen because of something I was uneducated about. Should I keep it on? Thanks.

It is only good in theory....
Will it block spills and dirt? Yes.
Why is it BAD? The oil from your fingers etc. transfer to the screen when you close it.
It keeps in heat, prevents (heat rises, the cover keeps it from escaping) the Mac from venting itself,….Macs vent from the FAN (convection).
from the conduction transfer of the metal chasis, ....and thru upwards heat radiation (thru the top platform/keyboard).
If youre worried about damage not covered by Apple warr. (such as spills, theft , drops etc) you can buy personal insurance for same which is very cheap per year.

Does using a keyboard cover block the fans?

I am using an iSkin keyboard cover for my MacBook Pro 15" Retina Display purchased in 2012. I was wondering if using this keyboard cover hinders the fans' performance.

Should I use a keyboard cover with the new retina screen?

Someone in an apple store told me I shouldn't use a silicone keyboard cover on the new 13" macbook pro w/ retina because apparently theres not enough space for it when the laptop is closed and its been causing faults? Anyone know anything about this?

It also blocks the air intake.
I use the original thin foam packaging that comes between the screen and KB from the factory to reduce debris gettting in and the monitor getting impressions.
Since it's light and thin, lets air get in under it and into the machine throught the keyboard, deflects spills it's been great for the last few years.
I use a external keyboard and scroll wheel mouse to take the wear and tear, I hate trackpads anyway.

Should i Not be using C++?

I am a 13 year old computer programmer and im going into Desktop Application Development. I started learning C++ thinking it would be good in this area but recently someone told me i should'nt be using it. Is this true? Should i be learning another programming language? If so what?

Desktop Apps for what? Windows? Mac?
For Mac learn Objective-C as etresoft pointed out in the other thread, but that is a minority on Windows.
For me, I would get the free Microsft Visual Studio C# compiler and learn that. The first language is always the hardest. After that it is relatively easy to pick up a new one.

ThreadLocals....when not to use?

Hi,
I've been doing some reading up on the ThreadLocal class this evening, while investigating some classes in Spring Security. It wasn't a class I knew much about beforehand but it seems very powerful.
A lot of the articles I've read about mention it's usefulness for security contexts and transactions, and stress the importance of cleaning up after using it to avoid memory leaks etc.
However, outside of the above 2 examples when should ThreadLocals not be used? From my limited reading so far it seems that these could (theoretically) be used to minimize the number of objects being passed into method signatures between the various layers of a web application....why would this not be a good idea?
Thanks.

Using ThreadLocal like this has 50% of the drawbacks of global variables.

Touchsmart 9100 use onscreen keyboard ctrl+alt+del to login

I have a Touchsmart 9100 and I can't figure out how to ctrl+alt+del to login to my network using the onscreen keyboard. I have it wallhung and will not be using the keyboard or mouse.

Greetings, Thanks for the reply. I'm not trying to use Ctrl-Alt-Del to clear anything, I'm not trying to use Ctrl-Alt-Del at all. Here's what I'm attempting:
Fire up a VM, log into the VM, run the customer's VPN
RDC to the customer's server
Run the management app on the customer's server that needs elevated privileges
In the RDC session to the customer's server:
I get a UAC dialog, asking if "I want to complete this action by entering my credentials on the authentic Windows logon screen" or "I don't want to complete this action"
I click the first option ("I want to complete...")
I get a second UAC dialog saying "Press Control+Alt+End" to enter your credentials"
I'm not able to press Control+Alt+End and have it go to the server in the RDC session, the VM is capturing it first; I HAVE tried it using the onscreen keyboard in the RDC session also without success
(I took screen caps of the dialogs, but, I've pulled an all-nighter working on another issue and couldn't seem to figure out how to insert them here... doh!)
So - no Ctrl-Alt-Del
Next time I need to get to the client's server I'll have to check the settings for keyboard shortcut forwarding. Thanks for the suggestion.

Interactive notifications not working with BT Keyboard

Hi all,
I just discover a very weird behavior (and I think it's a bug) on interactive notification, it does not work using bluetooth keyboards.
I'm using a iPad Mini with Retina Display (with iOS8) and Clamcase Pro Case.
When I'm in the home screen and receive a message, I can swipe down and enter my answer using the BT keyboard. However, when I'm on any other app, receive a message and swipe down, I cannot use the BT keyboard.
For example, I'm using Write app, receive a message and swipe down the notification to enter my answer, I keep writing on Write app (in background) and nothing happens in the quick answer field on notification.
I also tested with other BT keyboard and got same result.
Does anybody else see that behavior?
Thanks and regards,
Flávio Furlan

I can confirm I'm having the exact same issue on my iPhone 4S. I was attempting to respond to a text message by pulling down on it when it came through. What I noticed was that when I began typing, the application in the background was being affected, and nothing was appearing in the text window.

Can i use a Logitech Ultrathin Keyboard Cover with my iPad Model A1337

Can I use a Logitech Ultrathin Keyboard Cover with my old iPad Model A1337 (Wifi + 3G +64mb)?

Nope. The Compatibility listing on that very page, does not show the first generation iPad as a compatible device. Likely because it uses the built in magnets of the newer iPads to attach.
The Bluetooth connection should most probably work though. It just won't be able to be attached to the iPad first gen.

I have Mac Pro 2007, which have no bluetooth hardware. What should I do to use Apple wireless keyboard and magic mouse??? Can 'third party's internal bluetooth card' be used for this purpose? Help please...

You can find the Apple Bluetooth card on eBay for as little ten dollars (says its for the 2008 model Mac Pro, not sure about the 2007).
http://www.ebay.com/itm/Bluetooth-Board-iMac-and-Mac-Pro-922-8233-922-8233-/1208 49278570
Here is a link to a full explanation of the card and how to install it. Part numbers may differ a bit as that is an old article and newer models have come out.
http://www.xlr8yourmac.com/systems/Mac_Pro/Bluetooth_MacPro_install/Bluetooth_Ma cPro_install.html
Just make sure that the part will work in your model Mac Pro. To that end, you may be better off avoiding eBay and going to a parts reseller. There are even third party cards that use the internal Apple bluetooth slot.
http://fastmac.com/bluetooth.php
In theory, using a USB or PCI card will work at login so long as it is recognized by Apples drivers. You say you need to launch an application to use your current USB Bluetooth dongle? If it is not controlled by the Bluetooth icon in the menu bar then it must be using a third party driver of some sort. Unfortunately, I don't know off hand which USB and PCI cards are supported.

Dec 2012 iMac using bluetooth keyboard will not exit Target Display Mode

Hi! I have a new 27" iMac that I would like to use as a second monitor for my work laptop a late 2011 15" MBP. iMac is on 10.8.3 and Mac Book Pro on 10.7.5. Connected via a thunderbolt cable.
I can toggle on Target Display Mode using the command-F2 keys on my bluetooth keyboard connected to the iMac. If I understand directions correctly, I should use the same keys and keyboard to toggle off – but it doesn't work. I'm able to work around by putting MBP to sleep, which exits the iMac out of TDM.
I can use the work around, but...
1) it's annoying.
2) If I can't use the bluetooth keyboard to toggle, it would be nice to connect it to the MBP for use while in TMD. Unfortunately, the bluetooth keyboard is undiscoverable, presumably because it's still connected to the iMac.
I wonder:
Am I doing something wrong trying to toggle out of TMD using bluetooth keyboard?
or
Is there a way to enter iMac into TMD without using keyboard command? Maybe System Preferences?
Thanks for your help in advance!

Here's the solution: I had the same problem using my 27" iMac as an external display. The issue is, when you go to Target Display mode, your target computer, the iMac 27" locks the screen with your password.
To switch off TDM, type your password in on the iMac keyboard and press the enter key.
Now press COMMAND - F2 and the displays with switch back to two separate displays. :-)
I had to think like a computer to figure that out but it makes sense.
I also have the disappearing mouse pointer and have not figured that one out. I did all the software updates and I did not have this problem until I upgraded to Lion. It is definitely a software issue. I might have to open a case with Apple support. Not happy.

Just got Prosoft drive genius 3 software, and it's telling me that the external hard drive that i am using for my time machine back up drive needs to be defragmented. is it wise to do this or should i not??

Let's hope a couple things: that you have bootable clones of your drives also; that the backup drive for TimeMachine has over 3x capacity of the data you plan and are storing. I would also switch TM backup drives so you have a 2nd.
Fragmented free space affecting performance happens when the drive is too full which may mean there isn't enough free space for a full backup set.
1.5TB for backing up 500GB, while WD Green 3TB is $140 and WD Black 1.5TB is, about the same price.
I'd be worried about the integrity and directory, and whether you can afford to lose that drive. Defragging is also a very slow operation. the ideal: to just clone a drive, or start over with another drive and wait. cloning TM volumes has not been done or has it? SuperDuper hoped to but I don't think they or Bombich's CCC made it there.
Trouble with highly fragged is when free space gets to 20% normally, 1/3 or so though for TM volumes, and finding where and a chunk of space for the file being written. Does TM use large spare image files of like 2GB?
Best would be to ask in the TimeMachine section Snow Leopard
https://discussions.apple.com/community/mac_os/mac_os_x_v10.6_snow_leopard?view= discussions#/?tagSet=1009
where there are some good FAQ and tutorials, and people that know the ins-and-outs and shortcomings.

My brand-new iPod touch (5th Gen) battery takes a very long time to fully charge, even while not in use. Why is this and what should I do?

Just recently bought a brand-new iPod touch, 5th generation. To be exact, got it two days ago, this past Saturday, on 12/13/2014. Initially, when I first turned it on, it had a fully charge and I didn't need to charge it. I also didn't see anything in the very small and limited start-up guide you receive with it to charge it for a certain amount of time before use, or to use it until the battery dies, then charge all the way, like a lot of electronic devices have you do when you first purchase them.
So I was assuming I didn't need to do anything like that. First question, should I have charged it for a period of time before use? Should I have used it until the battery died, then plugged it in and charged it fully before use? Or is none of this necessary initially and iPod batteries are good to go from the start?
Please excuse me if this is an obvious question, as this is my first ever iPod. Anyways,like I said, nothing in the "instructions" said anything about that, so I didn't do it, I just used it until it got below 20% battery left, then I plugged it in.
Now for the battery itself, it takes literally a day or so to fully charge, even while not in use. Even if I use it for a while, turn off the iPod to make sure it shuts off all background data and apps, and then plug it in to charge, it still charges extremely slowly. I've never seen a device take this long to charge. As for the battery life itself, I'd say at full charge it lasts about 4-5 hrs, maybe 6, and then I have to charge it again. Meanwhile it takes around 24 hours, without me using it, to fully charge. If I use it while its charging, the battery decreases faster than it charges, and eventually I'll get the typical "20% battery remaining" message pop up.
I know it is charging, as the lightning symbol is next to the battery symbol. Specifically, right now, I plugged it in about 1 hr 30 minutes ago, and it has barely gone up. Also, whenever I press the home button to check the battery, I can see it jump down from about 50% to somewhere around 25%-30%. What is that about?
This is really frustrating, and I'm seriously contemplating either taking it back and trying my luck with a different iPod, or just taking it back and getting my money back. Any help and clarification on this matter would be greatly appreciated, and I'll answer any questions I can to shed more light on this.

It will take longer to charge the 5G's battery than either the 3G or 4G's battery.

Should I turn off my Mac Pro when not in use or leave it running?

I have been told I should never turn off my computer by some people, and others say that I should always turn it off when not in use! I use my Mac Pro primarily for music recording/editing in my home studio or word processing. Now that I have an iPad I use that for web browsing, email, FBing, etc. and I find myself on my Mac Pro a lot less. I get the basis behind both trains of thought; those who leave it on feel always stopping and starting up puts unnecessary wear on the moving disks, and those who shut down think if the parts are always moving they are bound to wear out faster. I am not as concerned with conserving power as I am with keeping my machine safe! If you have any information on this topic I would love to hear it. Thanks!

Providing you have a robust firewal and are not worried as a result about being hacked then leave it turned on and allow it to sleep. Make sure you allow the screen to sleep as well a that is the item that is more prone to damage by being left on all the time.
I never turn my machine off, never have with any of my Macs ever since my first one back in 1979-ish and have never suffered any adverse affects. Today, the power drain is so small when allowed to sleep that I doubt they would offend even the ardent 'turn off everything and pull out the plug to save the planet' person.
If you have an iPad or iPod synced with the Mac for email and iCal and address Book etc. then if you leave it on it should be up to date as soon as you return home, mine is anyway. With iCloud coming out very soon that may come into play even more so with all its advance pushing etc. Just a thought.
One advantage in leaving the machine on (sleep) is that you can access it from anywhere in the world should the need arise with the appropriate settings, which you can't if you turn it off.
Leave it on.
