How cold is too cold for a camera/lens

I've heard that when you use your camera in cold weather that when you bring it inside you should leave it in a sealed bag until it's at room temperature. I have no problem doing that. But how cold can my T5 tolerate as I'm walking outside taking photos?

You could probably find it on the Canon Web site. I think it's part of the published specs.
The sealed bag bit is an attempt to prevent condensation. Some claim it works, and others claim it doesn't.

How Hot Is Too Hot For Late 2008 Macbook Unibody?

I'm still in the process of adjusting to life in the world of Macs and I was wondering just how hot is too hot for the CPU to be running at with the Unibody 13 inch Macbook?

The sensors are set to put the computer in thermal shutdown at 212F to prevent catastrophic damage.

How many profiles are there for each camera?

When I develop my Nikon D700 raw files I have a choice of a number of profiles such as Adobe Standard, Camera Vivid, Camera Neutral Camera Portrait and various DX2 modes.
However with raw files from my Olympus E-P1 I can see only one profile;- Adobe Standard.
None of the E-P1 modes such as Vivid, Muted, Natural or Monotone appear to be emulated by Adobe.
Is this correct and how can I find out which profiles Adobe has actually produced for each camera?
Ian

Yes, Dorin is correct. For the E-P1 there is a single profile named Adobe Standard. You can build additional profiles using the DNG Profile Editor tool:

As I recall, a forum user was also building profiles and offering them for free. I think the E-P1 was included in the list.

When I take a video with my iPad, why isn't sharing with Facebook an option? Also if I take a video that is 1 min 23 sec, how is that too long for an email?

Why is 1min 23 second video too long for email?

How recently did you switch? If it's less than 60 days, then Verizon simply reinstates your previous account. The fact that you were on the EDGE plan and mailed the devices back, and they apparently are somewhere in the system, could cause complications, and it might just work out that you just go back on the same plan and they set you up with the same devices. I'm not sure how it will go - but since you are still being billed for the devices...

How "hot" is too hot for new MBP?

What would you consider too hot for my new 2.8Ghtz MBP?
Istat shows temps around 150-165f with fans running 2001rpm most of the time.
It feels very warm to the touch underneath.
Thanks

something is wrong with the new MBPs cooling system!

How big is too big for swf?

I have a swf file that has audio associated with about 15 slides. We were having some problems with it downloading and the people that host our LMS (Moodle) said that some of the problems may be related to our CP4 settings. I have the preloader set to 25% and the file is about 8.6 MB. They said to us:
Usually when hand-coding a SWF I require 100% of the SWF to be loaded before the SWF begins to play.
8.6mb is large for a SWF provided via progressive download. The optimum is no more than 5mb for users with a broadband connection. That may be part of the issue.
Is 8.6 MB really too big for a swf? What is the maximum size this should be? If it is too large what else can I do to shrink the audio as I'm sure that's a great deal of what is making the file too large?
Thanks very much,
Whitney

Hey Whitlowe,
I had a very similar situation. I received a 15 MB file from a "co-worker." The course was basically a converted PowerPoint into a Captivate course. The course had 53 pages and had heavy audio.
When I initially tried to publish it to my LMS the course took about ten minutes to load. I’m not sure if you use another authoring tool but I used another authoring tool called "Tool Book" a SumTotal product. I had to divide the captivate course into 8 SWF files. I then used Toolbook as a wrapper. The Tool Book file was 8 pages. Because Tool Book can read each page as a different SCO, the SWF files loaded one at a time.
For future courses, I am looking at getting a streaming server. I can house my audio on the server. The course would launch as a shell but would link to a streaming server for the audio/video. Not only will this improve load time but decrease my space on the LMS. I am looking into this option and not positive what the results will be, but I thought I would throw it out there.
That is the only solution I currently know of. I’m carious of any other solutions as well.
Good luck.

How hot is too hot for CPU's?

Melting through the bottom of the case like a runaway nuclear reactor is obviously bad...
BUT! What temperature ranges should be be looking at for standard air cooling with a quality heatsink and fan? I am running the intel provided retail heatsink and fan atm as the much more expensive unit I bought (the SP-94) wouldnt fit in my case at all.
So! Currently at idle my CPU temp is 36c, but it is also a little cold in my house. I have seen temps as high as 55c under load. Anything I should be concerned about as I am overclocking a bit? I am running 220x16 so running my 3.2 at 3.52ghz.
Thanks!

Increasing the FSB provides for better system throughput, but just increasing the multiplier of the cpu does not, therefore, you might want to try decreasing the multiplier when you increase FSB.
The formula is pretty easy. Take the max stable CPU Mhz setting you have, 3600(=225x16), and then divide 3600 by the new FSB value you want to try. The result will be what you should set the CPU multiplier to. Doing this repeatedly will eventually give you the max stable FSB value you can run @ your stock voltages, and then you can try to tweak up your multiplier again. You might have to up both memory and CPU voltages to get past the 3600Mhz total, but only do this one step at a time. You're looking for the MINIMUM voltage increase to achieve stability.
HOWEVER, I don't recommend radical OC'ing to anyone who has only stock cooling, or who has a big heatsink on the CPU only. The whole system needs to be cooled as evenly as possible: CPU, RAM, chipset, motherboard, video card, and should be done BEFORE OC'ing. Otherwise, unless you have deep pockets, you might go broke buying a whole buttload of replacement parts.

How big is too big for .properties file for a ResourceBundle?

The subject says it all. We are using ResourceBundles to manage the dictionary of English/French literals for our web enabling project. Our .properties file is currently 675 key/value pairs. How big can .properties files grow before they are too big?
Thanks,

The resource gets loaded into memory, so there's a memory cost that increases with the number of properties. (There's also a time cost when it loads, but that's only once.) And finding one of the properties requires a search, so there's a processing cost involved. But it's based on a Hashtable, so it isn't a major cost even if the number of properties gets very large.
So there's your constraints. The question is, though, what is your alternative when the resource does get too big? A database? That reduces the memory cost but increases the processing cost. I would guess you could let your properties file grow a lot before you were forced to go to a database, but actual testing would help.

How hot is too hot for a laptop

My new dv7t Quad edition laptop was recently delivered and I am wondering about the heat issue that others have mentioned. The computer does not get too hot to touch but there is warm air coming out of the vent almost all the time. When I have several programs running the fan seems to come on fairly often, which I understand is what it should do.
How do you tell if the laptop is too hot? Is some heat inevitable for an i7 processor?
I really like all the features of the computer but I want to make sure it is ok before the 21 day return period has gone by.
Thanks.
Jack
This question was solved.
View Solution.

To my knowledge, Maximum allowed temperature for Core i7 is 100°C and recommended is 80°C. If it heats up more, the CPU will enable thermal throttling, i.e. the Vcore and clock frequency multiplier will be forced down to 12x. This feature protects the processor die against dangerous overheating.
The warm air flow from vents is by design of the notebook. That is the specific reason for having the vents.
When ever the load on the system increases, the temperature increases. When the temperature inside the system increases, the speed of the fan increases.

How Large is Too Large for a Movie These Days?

Hi, we're developing our portfolio site which will have a LOT
of images that must be very high quality. So to keep quality up I
know we have to sacrifice file size (or vice-versa).
We've divided each of the sections of images into separate
movies so there is usually less than 8 images per movie. That way
someone would only need to wait if they clicked to see a specific
movie.
- My question is: What is considered 'large' for a movie file
in these days of broadband?
We are not planning on having preloaders for the individual
movies, and would like them to come up pretty quickly (so no
sluggishness or blank screens). I'm also looking into how to have
the movies loading in the background so that there would be less or
no delay once they are called up.
As an example, one of our larger sized movie tests showed a
size of around 350k for med-high quality, and about 750k for really
good quality. We prefer to have the quality of the latter, but
don't want people to get frustrated waiting.
On our local med-fast broadband (3.0Mb/Sec DSL) the large
movie loads up pretty much instantly and looks great. But we don't
want to alienate anyone.
THANKS!

I think you simply have to judge your audience - are they
likely to have ultra fast broadband or ten year old dial up
connections ?
My rule of thumb is to work for the lowest connection likely.
In the UK most medium to large commercial organistaions (my
market) have at least a 4mb connection so I optimise everything for
that. (Always bearing in mind that it's shared by hundreds or
thousands of users at any given location).

How large is too large for an Apple Mail folder?

My Apple Mail folder is around 3 GBs. Is there a limit to how big Apple Mail's folder can be?

Individual mailboxes are limited, but not the size of the Mail folder. In Mail 2.x, the limit for a single mailbox is 2 GB. Since each account has its own set of mailboxes, the limit for an Inbox, let's say, would be 2 GB per account.

How long is too long for a DVD?

I've been burning DVD's now for quite some time and have always thought that between 3 and 4 hours was normal for a DVD to burn in. Other's are telling me they can make DVD's in minutes!!! What's up...? Why are these time's so grossly out of proportion? Can I upgrade something or buy a better computer, what? Please help, all advice welcome

Just burning data to a DVD is very different from creating a video DVD with an application such as iDVD. Just burning data to a DVD can indeed take only a few minutes, depending of course on how much data is being burned. If you're creating a video DVD, though, then the application has to first compress the video to MPEG-2, and that can take hours.
Without knowing what you're doing, we can't say whether your experience is normal or not.

How hot is too hot for a northbridge?

I hope this isn't a stupid question but I happened to come across a monitor which measures the temperature of various components of my computer and I was startled to see that the temperature of the northbridge in my dual core Intel ranges normally between 135 and 145 degrees F. Can that much heat be a normal occurrence? Anyone know? Should I be looking for an aftermarket active heatsink? Or am I making too much of this?
Thanks a bunch.

Thank you for this. It would appear that with my configuration, an average temp. of 140 degrees F is perfectly now. Now I can go about worrying about something else.
Thanks again!

How hot is too hot for macbook batteries?

Does anyone know how to keep a macbook battery cool? I have a macbook with dual processor that is about 9 months old. Two weeks ago, the hard drive failed and was replaced at an Apple store. I now notice that the battery gets very hot after really short use times-like just checking Mail. I'm wondering if the battery can get hot enough to fry my hard drive, and if so, what to do to prevent this happening again as I've already lost enough data (I'm a newbie and still have not figured out how to back up to my new and very large external hard drive).
Thanks.

Hi wanster,
If your macbook still under warranty like you said (9 months), just bring back to apple, for battery shouldn't generate heat. Are you sure the heat was from battery insteadof the macbook processor?
Try to run battery updater 1.2 first and see if that will fixed it.
If the battery become hot, something internal might got short, and I suggest to take it off to prevent more damage to battery, macbook and yourself.
Good Luck.
