I wish to save a scatter plot comprising approx. 2 million points in order to include it in a LaTeX document. Using 'pdf(...)' produces a file of size about 20 MB, which is useless. Using 'cairo_pdf(...)' produces a smaller file, around 3 MB. This is still too large. Not only that the document will be too large, but also PDF viewers choke on this. Moreover, Cairo has problems

What is the rationale behind having both the delta and sd parameters for the power.t.test function? For the relevant noncentrality parameter, we only need the ratio delta/sd. If my effect size is given as Cohen's d, then I only got that ratio and not sd. As far as I see, in such a case, I can specify delta=d and leave sd at its default value 1. Is this correct or am I missing something?

Is there a way to have the distance between label and axis adjusted automatically? This is interesting in particular for the y-axis, when it is not known in beforehand how many digits the numbers will have. It may happen then, that numbers and label overlap. All examples that I found work by estimating the required distance manually in beforehand and then providing large enough margins, or

'rsync -a' updates the ctime on a directory even if no file in that directory has changed. A kind of workaround is to use '-O', but then the mtimes of directories are not preserved. (Usage example where this is important: maintain a copy of filesystem A in filesystem B, and use filesystem B as the source for incremental backups (e.g., with star). rsync is run before an

Is this correct behavior?

I'm admin on a samba PDC with 150 users, and as normal users they are quit "stupid". This means that they ofte deletes something that shouldnt have been deleted. And I find it anoying to restore their files from tapebackup. So would it be possible to get samba to "move" files instead of deleting them? This way I could allocate a disk to store deleted files for a periode of

I''m doing a series of ruby on rails tutorials and it got to a part where i need to edit the following files that should be automatically inside the public folder: dispatch.cgi,dispatch.fcgi,dispatch.rb but I have none of these inside my public folder. Is there a reason for this? And how can i change it so they are back The only files in my public folder at present are 404.html 500.html

Version is cvs checkout today at approx 0900 CET. Running on a debian/unstable box with dist-upgrade as of 0830 CET today, and with no windows installed.

Hi. Im am considering porting an c++ application to Ruby, and me company would also like to have an web-version of this particular application. If say there is an XML validator in the app. Then can Ruby and RoR share this in an easy way, so i wouldnt have to maintain 2 branches of the same XML validator. Best Regards.

I have presently a render :json which modify the current page if @request.save format.html { redirect_to(@request) } format.json { render :json => { :result => ''success'', :request => request_path(@request) } } .... but I would like rather to redirect to an index page I wrote this but it doesn''t redirect ... format.json {

My system is a debian/unstable box. I'm running daily cvs snapshots of wine and Lotus Notes R5.07. The problem is that it seems like wine isn't getting the redraw messages from the application or wine isn't sending the redraw messages to the application. So I get large areas of the program blank/black/see through to old gfx. It especially occurs with frames/framsets in notes. For

I have LabGroup and LabDesc which have many through LabDescGroup. I''d like to identify LabDescs which don''t have a LabGroup. This works: x = [] LabDescGroup.find( :all, :select => ''DISTINCT lab_desc_id'' ).each{ |c| x << c.lab_desc_id } y = [] LabDesc.find( :all, :select => ''id'' ).each{ |c| y << c.id } notfound = x - y But

Hello! I've tried to set up dovecot in conjuction with vpopmail, and running it under djb's tcpserver instead of (x)inetd. Btw - there was no reference to setting dovecot up using (x)inetd either in the manuals/faqs i read, though I didn't search all that hard. Anyway, back to my Q: vpopmail uses vchkpw as an authentication mechanism, and with tcpserver I can do relaycontrol (based

Hi. Im quite new to this Rails thing, but it seems like a good product so why not try it out whit a little prototype i need to build. What i want is to load any given XML file, and display it with some formatting. I have some XSD shemes to validate the XML files against, but its not vital rigth now. But how should i approach this task? At first it would proberly be a good idea to load the

Hi, fp is a data frame like this ,----[ fp ] | Frequenz AmpNorm | 1 3322 0.0379490639 | 2 3061 0.0476033058 | 3 2833 0.0592954124 | 4 2242 0.1275510204 `---- i want to find the "Frequenz" where "AmpNorm" is max.

Hi. I have for a while been trying to get my samba 2.2.1a PDC to be a NIS master and still maintain the password sync feature, without any luck. Now I made something that seems to work - but I would like to get your input to see if what I do is ok or it is something I should'nt do. 1: Samba uses passwd to sync the password (not yppasswd) 2: cron runs make in /var/yp every 15 minutes to
