Password avoidance

[Zaphod Beeblebrox]

Because actually it's a SECURITY thing. Apart from anything else...
It's no coincidence that the most secure Operating systems, UNIX,
AIX, Linux etc do NOT allow "passwordless logins".
I really do despair sometimes of the complete indifference of many
Windows users to computer security...

If a machine is physically secure, and auto-logs in to an LUA account
that has a password, what, exactly, are the security implications you
are so worried about?

Slartibartfast: No, that's perfectly normal paranoia. Everyone in the
universe gets that.

Once a day. Jeeeze.....
If you start up your computer LOTS of times a day a) it uses lots more
electricity than if you just keep it running and b) places excessive wear on
parts like the disk heads...

Of course I didn't say anything about more than once a day. What made
you "hear" that?

You may be using a computer for 60 years or more. 60 years, and ONE
logon per day. Now you've got over 21,914 logons. At 5 seconds each,
that's more than 24 hours wasted on repeatedly entering your password.

Man, that's nothin', I've wasted a lot more time than that riding my bike
and drinking beer. :-D

No he is not. I did not this year yet even after updates and as a matter of fact not
since Oct of last year. W2K3 Enterprise R2

Actually Gordon is 100% correct with that statement. I agree . Same scenario if you
open and close a 100w light in the room on a 110v 60hz circuit it will take up twice
that amount of power than if you would leave the light on for a 24hr period without
shutting it off. Same exact principle for the computer

That is fine if it is your own computer.
Do it at work that demands security, and you'll find yourself out of a job.

I watched an episode of Mythbusters and they said the opposite about the
light bulbs. I believe you can find the shows on line at their web site.

Off topic, I know, but I'd appreciate it if you could point me to a
web site that documents what you say about that 100w light.

What's "this"? Are you continuing to imagine that I was LIMITING
myself to ONE DAY? How many times do you log on during your LIFE? You
spend a lot more than 5 seconds logging on.

35 yrs being an Electrician. The draw when you open a light switch with a single 100
w bulb will be approximately +- 0.03 kvh at start up where as the light staying open
will draw 0.01 per kvh per every 10 hrs, Now open and close the switch 10 times per
day which will cause 0.30kvh registration on the meter as compared to a bulb
continuously burning for a 24hr period as approximately .025. Same applies to any
electrical apparatus be it a light bulb or the computer plus adding the opening
surge and then the burning ( running) time
But I will try and find the documentation on this Ken and will get over to you
(right now the documentation is in my head and I do not have my CA book at hand here
so as to show a hard copy

Thanks very much, Peter. Not to disagree with you, but if you can find
documentation on it, I'd like to show it to my wife.

What unit of measure is kvh?

 

[Seth]

What unit of measure is kvh?

kilo volt hour. The way electricity is metered when determining how much
you used and how much you need to pay for.

So your electricity supplier doesn't care how many amps you draw? Tell
me where you live, I'm going to build a new datacentre ;-)

I was told, by the journeyman electrician I worked for, that the terms
"open" and "close" originated "way back when." He assumed that when
candles were used to provide light, they had shutters; you open the
shutters to light the room and close the shutters to darken the room.

Another idea was the "barn door" shutters on Klieg lights:

That is totally ridiculous. All it takes is an outsider to get by
password security and it is all over with. What the OP wants is not
worth it.

I remember a DOD gal that managed a VMS cluster and she got pretty lazy
and wrote down her password, only because VMS does not allow
passwordless systems, and the system got compromised. She spent the
next year going from government facitly to facility teaching security
after that snafu.

They're all related. The amps you draw affect the rate at which you consume
KVH.

Bottom line, you pay for all the juice you use, no matter how you measure
it. I've lived in many states along the east coast of the USA and all my
power bills have been measured in KVH.

Maybe it's measured with a different unit on your side of the pond, but I
bet you still pay per unit of consumption regardless of what that unit of
measurement is. I pay for petrol in gallons. You pay in liters (or litres).
Doesn't really make a difference.

kilo volt hour. The way electricity is metered when determining how much
you used and how much you need to pay for.

Thanks, so that would be the semi-equivalent of kilo watt hour, our
unit of measure in the US. I'm really curious how voltage can be used
to measure power consumption.

Actually now that you mention it, KWH was what I was thinking of. Hands
faster than the mid sometimes.

I saw KWH instead of KVH and automatically changed the "watt" to "volt" to
match the acronym. Oops.

But in looking up to see if there is an actual official listing for KVH, I'm
not seeing one (at least not one that has anything to do with electricity).
Did Peter mean to say KWH instead of KVH?

 

[Sunny Bard]

kWh surely?

Maybe it's measured with a different unit on your side of the pond

Paying for electricity based on voltage * time would be like paying for
water based on pressure * time, disregarding how wide you open your tap
(or faucet!).
