Apr 30, 2016 05:45

Ok I'll find the book and reference it.

Motig

Apr 30, 2016 05:45

Huh? No. Do I have to?

Root Access

For all you Super Users out there. You have backups, right?

Motig

Feb 26, 2015 09:51

Hm, true...

Motig

Feb 26, 2015 09:50

oh, ook but thanks for inspirations anyway :)

Motig

Feb 26, 2015 09:49

So for $10000 daily loss you'd expect $10000 compensation from the ISP?

Motig

Feb 26, 2015 09:48

Hm...what would you expect as a reasonable penalty for breaking SLA?

Motig

Feb 26, 2015 09:47

We have an ISP with connection "for business" with 99,6% SLA which I was told is good enough...

Motig

Feb 26, 2015 09:47

but...uh, after quick googling it seems that configuring backups is nothing really hard...

Motig

Feb 26, 2015 09:46

well...damn, with all of this, I'm starting to favour Azure cloud again -.-

Motig

Feb 26, 2015 09:45

true

Motig

Feb 26, 2015 09:44

Well I'm planning to buy two more disks and implement 1+0 RAID because we're going have pretty much everything on it...Files, documents, also GIT repositories for application developement...

Motig

Feb 26, 2015 09:41

Bob: good question...

Motig

Feb 26, 2015 09:41

Decent enough for such small scale purpose...

Motig

Feb 26, 2015 09:41

Uh...this may be a country-wise price level difference? I dunno... to me, it seems to be decent enough...Intel Xeon, 4 GB Ram, 2TB HDD ...

Motig

Feb 26, 2015 09:38

well the server is actually $821 ... i miscalculated CZK to USD

Motig

Feb 26, 2015 09:34

Bob: ok, thanks for advice, that makes sense :)

Motig

Feb 26, 2015 09:32

this thing :) alza.cz/EN/hp-proliant-ml310e-tower-d515431.htm

Motig

Feb 26, 2015 09:31

It's really small scale...and it's a local pricing HP ProLiant with OEM Windows Server 2012 R2 Foundations

Motig

Feb 26, 2015 09:27

Oh...good point

Motig

Feb 26, 2015 09:26

It's stuff like financal services, insurance and financal B2B/B2C counseling...

Motig

Feb 26, 2015 09:24

That's the dilema I have... I need only DNS/DHCP/ActiveDirectory for now (company of 8 people) but company people tell me we want to grow big...

Motig

Feb 26, 2015 09:23

I know...but is it normal for companies to run absolutely everything on cloud?

Motig

Feb 26, 2015 09:22

I posted the question here superuser.com/questions/882829/… but it has been put to hold...so I'll try to reformulate it

Motig

Feb 26, 2015 09:21

Well my question is making a decision regarding the dilema between having On-Premise server or doing everything in Azure VM ...

Motig

Feb 26, 2015 09:20

hello...I was told I can have an opinion based question here :)

Motig

Jan 25, 2013 23:35

It should be already scaled....well....but it gave me an idea. thank you

Motig

Jan 25, 2013 23:30

anyway, what is R ? Something similar to weka?

Motig

Jan 25, 2013 23:30

though it's 0:30 AM here and I'm starting to nod off...

Motig

Jan 25, 2013 23:29

Well I definitely appreciate your help, I upvoted your answer

Motig

Jan 25, 2013 23:26

thank you for your effort

Motig

Jan 25, 2013 23:25

huh. that's strange. That shouldn't be. Output should be definitely from -1 to 1 ... not from -.49 ... I'll remember to check that out.

Motig

Jan 25, 2013 23:11

Would you like to share the knowledge of how are you using weka on processing the data I sent you?

Motig

Jan 25, 2013 23:08

I assume you are using weka...I didn't know it has neural network in it.

Motig

Jan 25, 2013 22:58

Thank you

Motig

Jan 25, 2013 22:56

filedropper.com/trainingdata2 .... is this more readable?

Motig

Jan 25, 2013 22:51

no, that IS one target variable. It is the linear regression slope. #2 line is the first set of inputs and #3 line is the corresponding computed slope. #4 line is another set of inputs and #5 line is the corresponding computed slope etc.

Motig

Jan 25, 2013 22:47

i'm working on something more table-ish

Motig

Jan 25, 2013 22:47

no...no the format is even more weird. odd lines is the output, even lines is the input

Motig

Jan 25, 2013 22:44

sorry for that, this is the format of the FANN library though I can quickly code another output

Motig

Jan 25, 2013 22:42

I can try using the return....

Motig

Jan 25, 2013 22:39

[filedropper.com/trainingdata](http://www.filedropper.com/trainingdata)

I'm realizing the format is a bit weird though...even lines are inputs, odd lines are the output. Would you rather the comma separated table with the output as the last column? I can do that. I'm really desperate for any help.

Motig

Jan 25, 2013 22:39

This is the source data, unscaled filedropper.com/es1000ticktrain

Motig

Jan 25, 2013 22:39

And yes, the tanh function. The Sierra Chart is just a charting software, it does have nothing to do with the NN, I probably shouldn't have mentioned the program at all.

Motig

Jan 25, 2013 22:39

By default output... you mean the price? So the NN would try to predict the future price instead of the slope? Well, I might try that.

Motig

Jan 25, 2013 22:39

pat: OK, I can post the raw training data, just give me a moment.

Motig

Jan 25, 2013 22:39

Thank you for the answer. All of my inputs are scaled to the range -1 to 1 you mentioned since I'm using the bipolar sigmod which ranges from -1 to 1 ... if this was the case, the neural network would stick to either -1 or 1 but not 0. My inputs are scaled as are the outputs.

Motig

Jan 25, 2013 22:39

I was thinking that my problem is maybe probably even more amateurish...I'm using the slope of the linear regression curve as the output which is just a value oscilating around zero as the price rise or goes down. I thought that might have something to do with my issue.
