Artificial star spikes and/or sparkle
I'm looking for a plugin/script/tutorial to create artificial spikes,
like they are typical for astronomic photographs of bright stars, eg:
(please take a look at the bigger image versions also)
The Gimp filter under "Filter -> Light and Shadows -> Sparkle" is not
usefull for this kind of look. Any recommendations welcome.

To rediscover The Ohm's Law, I = V / R,

we need a Linear Feet

which contains the origin of the axis.
We created a program,

does not contain the axis origin (I = 0 mA, V = 0 V)

Hi, I have just upgraded a switch to Fast Ethernet speed, and one of my
computers is detecting the speed as 10mbps for some reason- why is this?
Some systems do not properly negotiate the speed and/or duplex settings.
Also, if the swicth is hard set to 100 or 10 and the NIC card is set to
auto-negotiate, it may not properly negotiate the duplex. The best thing you
can do is to make sure that both the switch port and the NIC card are hard
coded to 100 Mbps at Full duplex. Here's a good chart of the problem. It's
talking about Cisco devices but it also holds true fo...Re: Interpreting Regression Intercept w Centered Predictors

Hello all SAS-users,
Does anybody know whether SAS has a procedure for estimating nominal
multinomial models with continuous covariates? If I have understood it
right, both GENMOD and LOGISTIC can handle only ordinal multinomial
models. CATMOD can handle also nominal ones, but it has limitations
for predictor variables (I have continuous predictors, CATMOD does not
allow them). Any help is greatly appreciated.

solution from SAS-help... I just wonder why I did not see it before

I want to ask the following question: are the slopes of the two lines are significantly different?

If I am not wrong, back propagation algorithm can also use hyperbolic

I believe I've set up AI correctly on my Solaris 11 Express machine.
However, when I tried an install with three different client, they all
failed in different ways. Can anybody suggest a fix of any of these?
The first one I tried had an ASUS motherboard with the ATI chipset.
It failed at the TFTP stage. The client sent the boot file name
correctly, but in.tftpd sent only a `tsize' option in response. The
client never responded to this, but just repeated the boot file name.
It was using the Reaktek RTL8111B/8168B Gigabit boot agent.
Next I tried an ASUS laptop with an Atom 450 CPU...
