Should I switch to 64 bit permanently?

I have a new 2010 MBP with 8Gb of RAM. Should I switch to 8Gb permanently? I shall be running a few VM's quite a bit of the time..

There is little real value in doing so, Firebird, given that 64 bit apps will still run in 64 bit mode when your computer is booted using the 32 bit kernel anyway, and quite a few disadvantages when it comes to potential incompatibilities with older software, drivers etc.
You will find a good article which looks at the benefits and disadvantages of booting into the 64 bit kernel HERE

If you are using Apple's Mail app 6.5 is the latest version irrespective of what a previous poster says. It does sound though that you are using a gmail account online via a web browser. Please confirm and fill in missing information.

Working with External editors & switching between 32 bit & 64 bit

Finally getting my Aperture 3 up and working (after days of frustration!) I am enjoying the new version now. BUT, my external editor (Photoshop Elements 8 for Mac & Topaz Fusion) will yet only work in 32 bit. After some early teething problems Aperture 3 now switches to whichever I choose - and allows me to use them for editing (eg adding text in Photoshop Elements) But, then it leaves me in 32 bit mode.
Is there any easy/quick way to switch back to 64 bit mode - without having to quit Aperture and re-open?
On a more basic issue - Elements tells me that for some edits it can only use 8 bit rather even than 16 bits. I assume that these 'bits' refer to the picture quality 'bits' Is this so - and what am I losing? Beside 8 'bits'!

Correction to this - Elements is working OK and saves directly into Aperture 3. But My Topaz plug ins switch to 32 bit and then Aperture 3 stays in 32 bit
Question still same - is there any other way to get back to 64 bit other than quit and re-open which is a long wat around?

Pre-shared key should be at least 256 bits of cryptographically random data

Hi all,
i need some info, i got a client IPSEC VPN form.
they asked that (Pre-shared key should be at least 256 bits of cryptographically random data)
what does that really mean?
Key consisting of 256 characters like abcdefg......till256 characters are done ?
or it means encryption we define in policy like
crypto isakmp policy 8
authentication pre-share
encryption aes-256 ????????
Please help me to understand this requirement for my cisco asa.

"Class Not Registered" after switching from 32-bit to 64-bit LabVIEW.

I recently upgraded LabVIEW 2012 from 32-bit to 64-bit. Now I'm getting an error that says "Class not Registered". It still works just fine with the 32-bit version.

Thank you Nathan and Sunshine. The problem is I didn't build the program - it came with the instrument. As far as I can tell this is what's going on: The vi's are replete with these activeX objects - all communication with the instruments is done through invoke and property nodes. After switching to 64-bit the very first sub vi has an error at the very first command (Err (-2147221164)). It's a reference (seemingly to a class but I actually have no idea what that means) passed to the "Open Automation Function". I'll attach a screen shot for the sake of overkill.

Itunes 11.1.5 does not recognize the switch to 64 bit mode from 32... won't open

itunes 11.1.5 does not recognize the switch to 64 bit mode from 32... won't open

Is there some background story to this that might give us some clue? An error message quoted exactly? Did you just do an update?
Try starting iTunes with the shift key held down. If it starts it is probably some old plugin presenting problems.

Should I switch my iPad off after using or lock off is enough?

Hi. After use iPad should I switch it off or lock off is enough? When I cover my iPad it locks off. Does iPad work while it is locked off? Thanks.

You can leave your iPad locked without any problem. Furthermore, it's recommended instead of turning your iPad off.
Your iPad, when it's locked, can receive mails, updates..., but it doesn't take a lot of battery, so it doesn't make sense to turn the iPad off

Why should I switch my Nokia 1020 for an Iphone 5c

Ive been using an Iphone 4 for the last 2 year's and that phone never missed a beat ! when my upgrade time came the cost of new Iphone's was too much for me so upgraded to a Nokia Lumia 1020. It's a nice phone with some great feature's but I really feel the need to switch back.
Please let me know youre opinions. Why should I switch back.
Please help as it's driving me crazy.

Who do you want to be in email for support, etc.? Do you want to be kwarp on the internet and on a resume? What image do you want to project? Individual or business or phantom or...? How good are you at juggling both references? Which would you want on a business card?
I wouldn't want to strictly maintain two IDs (nick versus real), especially for the long term.
Pick one and stick with it. Let the other be incidental.
I also believe these are detailed when doing the contracts, with at least partial explanations of how they will be used, so you can ponder your way during the application process.
Developer ID/Name (as registered by you) shows up as 'seller' as I recall - different from the name version attached to the copyright tag. You could use 'kwarp' as seller with 'greg lieberman' after the copyright and at least for this example, use both.

I have an iPhone 4S I am thinking about switching to the galaxy s3 because of the humongous screen, apple need a bigger iPhone, should I switch to an s3 or wait to see what apple will bring us

Should I switch to a galaxy s3 because of the huge screen or should I wait for apple to bring a bigger iphone

The s3 is a great phone, yes the screen is huge, no more squinting to read anything and also feels good in the hand unlike the strange size of the iPhone 5. Nice thing about android in general is how customizable it is. If you don't like the keyboard use a different one, use widgets to get to data right from the home screen rather than opening the app, unlock your phone with a pass code, pattern or facial recognition, tons of other options.
Down side about it, like the iPhone it has a mechanical home button, which will wear out.

I bought Lightroom 5 should I switch to Lightroom CC?

I bought Lightroom 5 should I switch to Lightroom CC?

Hi Philly,
There is no such application named Lightroom CC . However, we have Lightroom 5 which is already a part of Creative Cloud.
So, in short, Lightroom 5 is available as perpetual product and as a part of Creative Cloud(as of now).
The advantage of having it with CC is that you get additional storage space and an availability to future releases of Lightroom.
This should answer most of your questions. http://helpx.adobe.com/lightroom/kb/lightroom-creative-cloud-faq.html
Hope that Helps.

Randomly Dropping Traffic - Bad Tech Support - Should I Switch ISP?

Summary
I replaced the Verizon router with a Cisco router that support being an IPSec VPN Tunnel end-point. I switched from the coax to the Ethernet port on the ONT as the router doesn't have a coax port. Next I configured the IPSec Tunnel on the router, and I was a happy camper because I now have access to the company LAN.
[Fast forward a week.]
Phone calls started sounding choppy so I investigated. It now seems like there is a ~15% packet loss for VPN traffic. How did that happen? I spent 2 full days triaging the issue ... I'll spare the details ... and I narrowed down the packet drops to somewhere between the local Verizon ONT and the remote site modem.
As a test, I temporarily switch my Internet connection to my handy iPhone 4 hotspot (thanks AT&T )
To my surprise ... no packet loss. So that narrows it down to the ONT and the Verizon network. So I contacted tech support and wasted almost an hour with someone who was absolutely no help. To top it off, he tried to sell me on some Expert Care package -- apparently he himself is neither an expert nor does he care -- for me to get my service issues resolved.
Now the question for me is, should I continue struggling with this subpar support service, or should I switch to another more helpful ISP?
Solved!
Go to Solution.

Physical Connections:
PC----[Router A]--(Ethernet Port)[ONT]===={{{{Verizon Cloud}}}}==={{{{Time Warner Cloud}}}}====[Modem]----[Router B]
The central VPN point is Router B.
Router A is a remote VPN client. Alternatively, if VPN is disabled on the router, the PC behind Router A can also connect with a software VPN client.
No.
The configuration is fine.
The IPSec tunnel gets established.
The VPN has worked fine for two weeks.
Starting yesterday, random IPSec encapsulated packets from Router A to Router B are getting dropped.
~30% packet loss.
This happens with either the PC or Router A as VPN client.
(Please note that Router A is not the Verizon supplied Router.)
Also, pings from Router A to Router B outside the VPN tunnel have 100% success rate.
I narrowed down the packet drop to somewhere from the ONT to maybe the Verizon clould (packet filtering or inspection?).
Can you reload the ONT?
Thanks.
Will do.
Done.
There only is a 3rd party router.
There is no Verizon supplied router.
PC----[Cisco UC520 Router]====[ONT]

Is it possible to switch from 64-bit to 32-bit on a x86_64 install?

Well I was a noob when I installed Arch, and still am, but I had enabled the multilib repository not knowing that it would have so many conflicts with what I would like to do (namely, PlayOnLinux). Is there any way that I could remove the 64-bit libraries that I have installed, remove the multilib repository, and have an all-32-bit system? The loss of RAM won't be a big deal for me since I will most likely just install a PAE-enabled kernel (if that's possible in Arch) to make up for it (that's what I had done in Ubuntu).

I tried the switch... but... I got fubar'd It might have been an error in the way I had my system set up though, because I did follow every step that was posted. After I rebooted from doing the switch, I was no longer able to boot, and I was getting a "cyclical error" or something like that. I'd just try the 32-bit chroot environment if I were you. I don't have it working yet (someone is helping me out with it), but once it's done, it should be a much cleaner and safer way of using 32-bit programs.

You might also want to try: ssh -X myserver; /opt/NX/bin/nxnode --agent to test the basic functionality. Session log follows:

I guess there are two problems with it:
1. It couldn't resume. (in fact I want to start a new session. I don't know where are the old session information: I already removed all related file in the home folder.)
2. the error with "nxagent". It says it couldn't load libXcomp.so.3. I don't know how to install it.
Any help will be appreciated.. Thanks!
