...a means of providing a rollback mechanism for an upgrade (which I learned from others long ago). So essentially, before an upgrade you split the mirrors and upgrade one side or the other. If your upgrade goes well you sync one way, if your upgrade does not you sync the other (much hand waving and chanting going on, as its more complicated than that, but that is the essence of the solution). Recently, I was asked to do the same thing but with a raid 1+0 solution. Its easy, enough to break the raid 1 volumes underneath, but then how do I use the broke off volumes to form the duplicate strip. Pictur...

I''m fairly new to the Ruby world, particularly WxRuby, so please forgive me if this is ground that''s been covered in the past. I''m trying to load a frame from an XRC file (created using DialogBlocks), and I''m having trouble getting an instance of the Gauge object using the Wx::Window.find_window_by_xxx methods. I''m trying this on Windows XP,

As everyone probably realizes, I''m getting swamped with incoming problems and tickets and I still need help triaging the tickets. James Turnbull has volunteered to help some, but I think we need more than one person. We''ve had a few people step in once or twice, but I''d like to be able to depend on Unreviewed tickets getting handled by someone else, rather

A large test I ran on flac 1.0 recently finished so I thought I'd post the results. I took about 60 CDs, totalling around 30 gigs uncompressed, and compressed them all using all 10 of flac's default compression modes (-0 through -9). The CDs are of a wide variety of music; I think the only major genres not represented are country and rap (freudian slip). Anyway, the raw numbers: Opt

During one of my controller actions I want to call an external machine before I do anything. It''s not a real web service, more like a REST-style thing where I''ll just be tweaking a servlet running on another machine and sending it some data. Does Rails give me anything to work with for doing that? I read the web service stuff but it''s overkill for what I need. I

Dear Friends, I''d like to have a development suggestion for Rails. Rails is an amazing framework, and clearly it''s weakest link is that it relies on HTML in the end, which is not always the most appropriate GUI out there. Another option could be XUL. Mozilla-based browsers (Firefox) can run XUL apps right out of the box, others could use the XULRunner application. Here you can

Hi, Could you tell me if I'm wrong ? I've understood that Wine can run a dos EXE program under a linux/unix environment : I launch Wine with proper arguments and with the program name, and the magic happens... Thus, if my program does some file input/ouput, will it also work ? Will I be able to access the outputted file via my old bash ? In fact, I would like to call an EXE DOS program

So it throws back a some-what common error message, but I'm not sure if it's related: Code: fixme:win:EnumDisplayDevicesW ((null),0,0x32c268,0x00000000), stub! fixme:wininet:InternetCheckConnectionW fixme:wininet:CommitUrlCacheEntryInternal entry already in cache - don't know what to do! Here's what I think the main error is. I tried googling it and it seems that I'm

Do you know if Samba 3.0.15 was built for AIX? If so, where can i find it? Thanks, Sig --------------------------------- Click here to donate to the Hurricane Katrina relief effort.

Hi ! We are curently deploying an 8 nodes cluster where we have a RHEL 6 license at great costs (~14 k$/y). It will be our new production environment for mission-critical services. Now our aging developpement server (old p4 with 1.5 gig of ram) need to be updated. We will be installing on hardware as close as possible to the new production servers, just not in a rack... For the developement

I''m still thinking about how my puppet deployment will go. Right now, I''m thinking each of my machines will have their network interfaces defined/configured by puppet. But, I''d like to generate my zone files and dhcpd.conf from this data as well. How do people generally do this? I expect I''ll end up generating the nodes.pp files from some database, but

Hi, Ady wrote: > If users want to find the "--uefi" parameter for the isohybrid command, > it is already there, documented. Yes. But it does only work with non-SYSLINUX boot images. It is undisputed that one can work around that problem on a hard-disk-like medium by simply not using ISO 9660 but a set of partitions and SYSLINUX EFI software. But this does not help with

Interesting figures. Some corresponding figures for flac 1.0 for a set of 404 CDs, with a total of 4357 tracks are: Opt Uncompressed Compressed Ratio Encode Time --- ------------ ----------- ------ ----------- -8 234507744748 127468328349 0.5436 n/a Admittedly, this set includes at least one country album, and has a fair share of jazz in it. The worst-case track in this set

I''ve noticed that I phrase a lot of shared behaviours in plural, eg describe "All payment_details views" How about a "they" alias to "it" so you can write describe "All payment_details views", :shared => true do they "should have a card number field" do # ... end end WDYT? Ashley

Dear useRs (called Frank Harrell, most likely), after having preached for years to my medical colleagues to be cautious with stepwise selection procedures, they chanted back asking for an alternative when using mixed models. There is a half dozen laXXX packages around for all types of linear models, but as far I see there is none for mixed models such as lme. Even boot.stepAIC (which I

I have a partial, it''s a shopping cart display, it''s designed to appear on several different pages of my site. One of the buttons on the shopping cart empties the cart, and then I want the calling page to redisplay. In other words, the cart controller needs to return the visitor to the same page -- however since the cart could appear on any given page, this has to be
