RFC: A Preview Of The Phoronix Graphs With Iveland

From what I have read, this would be the correct formula to use as far as I know.

You misunderstood. The formula is most probably correct. My question was that why do you think that standard deviation is more interesting/useful than the extrema of the deviation?

For example I have a machine which manufactures screws.
In general I want to know when the tool in this machine gets worn out so I measure the screws at an appropriate point and I calculate the standard deviation from the size given on the technical drawing.
But if for some unknown reason the tool breaks (the standard deviation is still in acceptable range) I would probably start looking at the min/max deviation which may or may not shed some light one what circumstances caused the problem.

[bridgman]

I suspect Michael went with standard deviation rather than min/max because so many people have asked for standard deviation

I agree that min/max might actually make more sense but I don't think anyone has asked for it before.

[Michael]

Yeah I went with standard deviation over having the code already written for the calculations in it since it's used elsewhere in PTS, it's simple / easy to understand, and that's what the people have been asking for.

[curaga]

Yeah, definitely better than before.


The logo looks rather bad though:


- inconsistent

The last vertical line is blurred, but the rest is aliased and blocky

- ugly

The aliased and blocky
The right-bar blur is a bit too strong as well.

By dynamic rendering, do you mean client side using js? I hope there'll also be a static view for when js is disabled.

Both types look good in any case - much better than the old ones.

I plan to have a variety of paths including JS, pure SVG, and PNG... Though when thinking about it yesterday, I may drop the PNG support altogether as all browsers should be fine besides IE with SVG.... Or may drop PNG after PTS 3.2.

Yeah, definitely better than before.

What right bar blur do you refer to?

[curaga]

[Michael]

Oh with the logo, yeah. Right now the image is being automatically scaled to size, but will end up making it one set size.

Here's where we're at as of Sunday morning:
