It is definitely a minor concern, because just about all of the new malware for the Mac released last year was Java based. However, if you allow Software Update to keep your Mac updated, you probably don't even have Java enabled at this point.

See:

It is quite easy.

It's a good idea to disable Java in your Web browser(s).

In Safari, this is done by unchecking Enable Java in the Security pane of the preferences window (accessed by choosing Preferences from the Safari menu).
In Firefox, select Add-ons from the Tools menu, and in the Plugins pane, disable anything related to Java.

LEAVE ANYTHING THAT IS CALLED "JAVASCRIPT" ALONE. Despite the name, Javascript is not related to Java, and is not a problem.

Disabling Java on your Macintosh entirely is also probably a good idea if you don't have any applications that use Java.

Common applications that use Java:

Adobe's Creative Suite
Open Office apps (NeoOffice, OpenOffice/Mac, LibreOffice)
CrashPlan
jEdit
Freemind

To disable Java entirely on your Mac, open the Java Preferences utility in:
/Applications/Utilities
and uncheck the checkboxes.

I'd be interested in low-cost or free VNC hosts as well as clients recs as Thailand's internet is NOT free. I use Tor browser to anonymize one's basic browsing to access anything, but better to be "safer".

There are a few free options available, but it would help if you tell us
what the host and client platforms are, and whether this local (LAN) or
across-internet.

Hi, Barry.

I actually took it in for the iMac hard-drive recall/replacement (which I ended up not needing because I didn't have the affected drive). While it was in the shop, the guy noticed that I had some dust behind the screen. Since it was covered under Apple Care, he asked if I'd like a new screen. So I said yes, because the dust was really noticeable.

The screen problem hasn't returned, so I'm thinking (hoping) I resolved it by unplugging it and replugging it in.

Sometimes a restart will fix things, especially if you also unplugged it. Would have been embarrassing had you taken in the machine (obviously unplugging it unless you have a several mile long extension cord) and they found out it was okay. Do, though, save the paperwork. Even if you are almost out of AppleCare, any repair does have a 90-day warranty.

Yes, I thought I'd better cover the basics before packing up an iMac and complaining about the monitor. Thanks!

Dang. It's started up again. No settings have been changed since the last time, and the computer hasn't been moved. Blech.

Howdy Otto.

I have a Nikon D60.

In Menu

Shooting Menu

Image Quality

The Nikon D60 available settings for Image Quality are:

JPEG Fine
JPEG Normal
JPEG Basic
NEF (RAW)
and
NEF (RAW) + JPEG basic

Then the next settings menu is for Image Size.

Large = 3872x2592, 10.0 MP
Medium = 2896x1944, 5.6 MP
Small = 1936x1296, 2.5 MP

I normally keep it set to JPEG Fine and Image Size Large 3872x2592,
10.0 MP.

A typical JPEG photo will be 3.5 MB at 8.6 x 12.9 inches, 300 ppi.

As Otto suggested, there is no camera DPI settings.

> I normally keep it set to JPEG Fine and Image Size Large 3872x2592, 10.0 MP.

That is YOU choosing inches in a processing program. The camera doesn't know inches, and simply creates an image with (a) a specific pixel number, and (2) a specific storage algorithm.

> A typical JPEG photo will be 3.5 MB at 8.6 x 12.9 inches, 300 ppi.

IFF you tell the processing software either the DPI value or the inch dimensions.

If you choose to print a full image on a 4"X6" piece of photo paper, it will be over 600 DPI.

Thanks Jim. This is what I would've replied. The camera knows nothing of
the size you will view or print, so DPI is meaningless.

This is not the case.

As I stated and copied settings directly from my camera, the camera
DOES have the ability to determine the size and quality of an image.

Whether you call it dpi in printing terminology or ppi in screen
display terminology, or large, medium, or small image size settings,
the results are digital photos that have a larger or smaller physical
dimension in inches or cm when transferred to computer.

Yes, it does, as does any digital camera, size being the pixel dimensions
and quality being the degree of JPEG compression. What it does *not* have
is the ability to allow you to select a PPI or DPI figure. These have
meaning only when combined with the size in inches and the camera knows
nothing about inches, as Jim said.

Your example is 8.6 x 12.9 inches at 300 ppi. True, and it would also give
you any other size and PPI combination totalling the same pixel dimensions,
such as
2.16 x 3.23 @ 1200
4.32 x 6.45 @ 600 PPI
17.28 x 25.81 @ 150 PPI

The camera knows nothing of that, only the pixel dimensions.
