Actually, can any of you still get RPD? It is no longer on either
server I use.


Still on giganews and aroad arunner. Still verges on on-topic,
sometimes.

In the week or so giganews has carried RPD DOT WHATEVER, it looks to me
as if a good day is 20 posts in the trafficked one, which is not
incidentally the only one I voted in favor of.

What rec.photo.digital?
It has dispappeared from both servers I use.


Roger, I still see a lot of posts on rec.photo.digital. There were 180 of
them just this afternoon.

I do.

OTOH, I think this thread has already developed more traffic than I've
seen in a week on the 4 digital groups. OK, not quite, but I'm not
seeing much.

The four new groups are still not on quite a few major servers, so give it
time. Don't expect the traffic in any of the four new groups to get as
heavy as RPD. Instead, expect lower volume targeted traffic in each group.
It takes a long time for the chips to fall after new groups are created.
Three out of the four new groups are actually doing very well for groups
less than a month old.

20-50 posts per day is considered healthy traffic for a rec.* group. Do not
use RPD's 300+ posts per day as a base for comparison. Three out of the
four new groups are doing much better than most new groups less than a
month old. Just think..you looked at the new groups and thought "Where's
the traffic?". Imagine how many people are doing that instead of showing
their support by starting an on-topic thread. ;-)

I see that you use Supernews. They still carry RPD. RPD was not scheduled
to be removed as part of the reorganization. Maybe you need to refresh your
groups list. If it is still a problem, contact support [at] supernews dot
com.

That was one of the first things I tried.
I lost two groups just after the first of the month when I changed
from DSL to cable. I was still using the same settings and the groups
were missing from OE as well as Agent. It showed as subscribed, but
refreshing did not find RPD. I then switched to the cable's
newsgroup, SuperNews. Still the same thing.

After trying numerous routes I finally ended up unsubscribing from the
two groups, shutting down and restarting Agent, "then" refreshing the
newsgroups and RPD was there. Then resubscribing.

The same route was necessary in OE.

Something had to have changed in the reader(s), but the confusing part
is "both readers"?

Yes, I have multiple firewalls and my computers check clean.

At any rate I can again read RPD.

I cross posted this to the 4 digital groups as it pertains to all.

It's been about 2 1/2 years since I went digital, first with the Oly
E20-N and now the Nikon D-70.

I started out with two sets of AA NiMH batteries and added a third.
One set consisted of 8 2000 MAh batteries, one set of 4 1800 MAh,
batteries and one set of 4 1850 MAh batteries.

One of the early 2000 MAh batteries failed early on. Not too long ago
a second failed. In the last week I had one fail in each of the other
two batches.

They were heavily used at first, but since the D-70 have received only
occasional use. They have been conditioned twice in the last year.

I didn't name any brands as the failures seem to be pretty well
distributed between on and off brands.

Considering the cost of NiMH batteries, I think I ended up with
reasonable life out of them.

Likewise the rechargeable Lithiums are rated with both a cycle life
and calendar life. The proprietary battery with the D-70 seems to
have tremendous capacity, or longevity, but it's life is still rated
in the neighborhood of two years.

The great 'dedicated' battery rip-off is why I'm seriously considering the
new Pentax *ist DS - uses AA's.

Proprietary batteries are a curse - whether they are for laptops, video
cameras, or still cameras. Full marks to Pentax for building a camera that
uses an inexpensive future-proof power source.

Hi all

As a point of interest the guy in Jessops (Canterbury) also said that
topping up was a bad idea until the batteries had been conditioned. Ths
entails fully chaging then fully discahrging them 4 times. Discharge them by
normal use and dont force the issue by up loading vast amounts of data to
your PC - no topping up charges in this time .

This is supposed to considerably extend the useful life of batteries .

Hi All:


Some points about Lithium cells.
Lithium cells are very different from NiCad or NiMH cells.

1- Lithium batteries have a shelf life, they will go bad wither they are
used or not. How long the shelf life is depends on the manufacture and the
design of the batteries. This is a good reason not to buy used or old
lithium batteries.

2- Lithium batteries have a limit on of the number of times they can be
completely discharged and re-charged. This is about 500 to 1000 times
depending on the manufacture and the design of the cell. Un-necessarily
completely discharging a Lithium battery wastes life of the battery.

3- Lithium do not have any memory effect. In fact the best way to extend the
life of the cell to the maximum the self life will allow is to keep them
fully charged. It is best to keep them in the charger and fully charged.
Lithium batteries in the proper charger can not be over charged.

4- Charging a lithium battery in a charger not designed for that battery
risks a fire. Without proper charging lithium batteries can explode or burn
up.
