About compositional data analysis
The compositional data xi=(x_i1,x_i2,...,x_in), for each fixed i , xij>0, and sum(xij)=1; I want to compare the mean( u_i) of several groups i.e. H0: u_1=u_2=...=u_N or H0: u_11=u_21=...=u_N1 Are there any ANOVA tpye tools to do this work in R? Thanks, WEN S Q [[alternative HTML version deleted]]

validates_presence_of
I am just going through the book and I come across a problem with the code in the app/models: validates_format_of :image_url, :with => %r{^http:.+\.(gif|jpg|png)$}i, :message => "must be a URL for a GIF, JPG, or PNG image" It seems to moan when it''s empty even though I removed :image_url from validates_presence_of. How should I make it optional?

debian unstable : mutt polling imap mailboxes
Package: dovecot Version: 0.99.10.4-2 I am accessing my IMAP folder on my ~/Maildir using mutt via Dovecot and I have this problem whereby mutt incorrectly reports I have new mail in a "mailboxes" polled mailbox. This happens all the time when I press the key bound to change mailbox. I use courier IMAP at school, and I have not experienced this problem. A bug with dovecot or mutt?

Frequency table
This must be FAQ, but I can't find it in archives or with a site search. I am trying to construct a frequency table. I guess this should be done with table. Or perhaps factor and split. Or prop.table. cut? findInterval? Argh! Please correct me if what I am looking for is not called a "frequency table". Perhaps it's called grouped data. > zz$x9 [1] 65 70 85 65 65 65 62 55

Dovecot's brittle configuration syntax
Hi there, Whilst trying to come up with a minimal configuration for Dovecot: http://dabase.com/blog/Minimal_Dovecot/ I noticed the configuration syntax is a bit admin unfriendly. It's easy to get an infamous Error code 89. Is there any back story to the grammar or language this configuration is in? Kind regards,

Comparing linear regression coefficients to a slope of 1
Hi! I have a question that is probably very basic, but I cannot figure out how to do it. I simply need to compare the significance of a regression slope against a slope of 1, instead of the default of zero. I know this topic has been posted before, and I have tried to use the advice given to others to fix my problem. I tried the offset command based on one of these advice threads as follows:

Samba slow on MacOSX Yosemite
Samba is very slow through Finder on our Gigabit network (she's using a USB3 adaptor), especially when it comes to listings and such on my wife's computer. This is my samba configuration on Archlinux: http://s.natalian.org/2016-05-14/smb.conf (I'm always running the latest https://www.archlinux.org/packages/extra/x86_64/samba/) And this what the mount looks like on the MBP: //rufie

Windows 10 share failing
I think its related to https://lists.samba.org/archive/samba/2016-September/202918.html I am not very competent at Bugzilla. I scanned the list on https://bugzilla.samba.org/buglist.cgi?quicksearch=windows%2010 and I couldn't find one I could track for this problem to be fixed. I filed an issue upon https://bugs.archlinux.org/task/50847 since I use Arch. I will try and provide a tcpdump

ices2 realplayer
I'm rebroadcasting a realplayer stream and there are two problems. The icecast2 sounds tinny and its delayed something like 3secs. Any advice to perhaps use speex as it's talk radio? Can I cut the delay? Here is my ices2 config: http://static.natalian.org/2006-06-21/ices-alsa.xml Here is details of the feed, so you can take a listen:

Styling Markdown approaches
Hi guys, I wrote a markdown based Web editor thing for my sister: http://ws.dabase.com/ And she has trouble styling blocks of markdown. Since <div markdown=1>markdown here</div> does not work on my Debian markdown binary. Is there a formal definition of markdown? Or some sort of conformance test? And certain markdown implementations I should be using, and certain ones I should be

compositional data: percent values sum up to 1
again, under another subject: sorry, maybe an all too trivial question. But we have power data from J frequency spectra and to have the same range for the data of all our subjects, we just transformed them into % values, pseudo-code: power[i,j]=power[i,j]/sum(power[i,1:J]) of course, now we have a perfect linear relationship in our x design-matrix, since all power-values for each subject sum up

step, leaps, lasso, LSE or what?
Hi, I am trying to understand the alternative methods that are available for selecting variables in a regression without simply imposing my own bias (having "good judgement"). The methods implimented in leaps and step and stepAIC seem to fall into the general class of stepwise procedures. But these are commonly condemmed for inducing overfitting.

Icecast2, ezstream and reverse proxy
Hello Ezstream is working well locally with Icecast2 on port 8000 on a Debian Wheezy platform. However, I use a reverse proxy (Pound) to pass all requests from the Internet for x.mysite.com to backend localhost:8000 i.e. my Icecast2 server. This works fine, i.e. x.mysite.com brings up the Icecast2 Status page. My problem is with the ezstream xml configuration <url></url> setting which

Icecast2, ezstream and reverse proxy
Hello, Correct me if I'm wrong, but what you get from Icecast *is* HTTP. Anyway, we use proxying because on our server, some of our clients cannot connect to port 8000 without bypassing their company firewall, and we don't have the possibility to add another public IP. So with Apache, here is what we do : ######################################################################## # #
