• In terms of load handling, which is better: one server or two of equivalent power?

  - by seldary

  My goal is to figure out if i'm better off with one strong server, or multiple weaker servers with a load balancer. Does the fact of splitting the load between servers have an effect on the total load my website could take? It's hard to single that out, because there are of course a lot of parameters that affect the results, so some assumptions: Putting failover considerations aside - I know it matters, but for the sake of the question's simplicity, lets assume nothing fails. The servers in the multiple servers option have an accumulated "power" equivalent to the one server option (about the same amount of cores and RAM space). If that is too theoretical, here is a concrete question that could help: Suppose I have several instances of exactly the same server - lets call it S. Suppose that server S can serve a load of up to X calls per time unit. Will two S servers with a load balancer serve 2X calls per time unit? significantly more? significantly less?

• Delphi : What is the best way for passing data between forms?

  - by Flom Enol

  It may seem a little newbie, but I really have got problem with it. I have a form (not the main one)for getting many different data form the user and I want to pass it to a manager class for creating an object with these. The problem is that I can't have this class to use the other unit (getting circle uses) and also it doesn't have access to the manager class instance (which is in main form). So, what shall I do? I've already considered using public variable but I have a bad feeling about it (regarding OOD patterns). Any ideas? thanks in advance.

• BackupPC back-up has not been finished in 12 hours(!)

  - by chronoz

  I installed BackupPC toda on a server and set it to do a back-up 12 hours ago... while it's been backing up since, it seems very very slow and it's not completed yet. It's just backing up a testserver with a total disk usage of 1.8GB. What could cause the back-up process to be so slow? rsnapshot always worked wonderfully fast, but I want to improve my back-up solution. df shows that the size on the back-up disk is actually still increasing.

• Confused with objects in Ruby

  - by David

  Ruby Newbie here, I understand that everything is an object in Ruby, one thing that I wasn't sure about was understanding Variables. Variables basically give reference to objects (correct me if I'm wrong). During an instructional video, the teacher did a demonstration which went as below: (irb) a = 100 ==> 100 b = a ==> 100 b ==> 100 This part I get, makes total sense. Then he did a = 50 ==> 50 b ==> 100 If B is supposed to point to what a was set which was a 100, why does b still point to 100 if a has now been set as 50?

• Random Connections to MySQL refused (Error 111)

  - by joatis

  A Perl/CGI webapp that has been running fine for almost a year has started to randomly been unable to connect to a remotely hosted MySQL. The Error thrown is : Can't connect to MySQL server on 'xx.x.xxx.xx' (111) Reloading the page often solves the problem The client is using Perl, DBI and SSL to connect to MySQL using the same configuration file each time.

The servers firewall is open to the client's subnet. The mysql user has permissions from the client's subnet. I have my host looking into the problem but so far we're all stumped as to way the occasional connection is (increasingly getting refused) Any advice what to check that would cause the random refusal of connections?

• Windows 8 Task Manager RAM Usage Accuracy

  - by user264892

  The new Task Manager has a great UI in windows 8, however, there are some discrepancies in the data I can not account for: Machine: 8 GB of total ram. (This is a physical machine, not a virtual) The processes tab shows 45% of Memory utilized. The listed process do not add up to 3.5 GB of RAM, but instead add up to 0.948 GB. There is no "processes for all users" option. The performance Tab Shows: In use : 3.6 GB Available: 4.4 GB Committed : 4.1 /9.2 GB Cached: 3.7 GB Paged Pool: 376 MB Non-paged pool: 135 MB My reading of this says I have ALOT of "cloaked" processes running some where eating my ram. How do I interpret this data and how do I verify it?

• Haskell, list of natural number

  - by Hellnar

  Hello, I am an absolute newbie in Haskell yet trying to understand how it works. I want to write my own lazy list of integers such as [1,2,3,4,5...]. For list of ones I have written ones = 1 : ones and when tried, works fine: *Main> take 10 ones [1,1,1,1,1,1,1,1,1,1] How can I do the same for increasing integers ? I have tried this but it indeed fails: int = 1 : head[ int + 1] And after that how can I make a method that multiplies two streams? such as: mulstream s1 s2 = head[s1] * head[s2] : mulstream [tail s1] [tail s2]

• Overriding Magento Admin Controller, for Beginners

  - by Knowledge Craving

  In the Magento Admin section, I want to override the "Sales/Order/ShipmentController.php" controller file of the core Mage. I have tried rewriting the URL, using the "from" & "to" tags, but in vain. I don't know what is the actual & correct way of doing this, as I'm a newbie in Magento. Please anybody provide some good fundamental & correct answer, so that at least the concept gets clear. Also, if possible, please tell me, what is the actual purpose of the controller, for both the frontend & the back-end? Any help is greatly appreciated.

• width:auto for <input> fields

  - by richb

  Newbie CSS question. I thought 'width:auto' for a display:block element meant 'fill available space'. However for an <input> element this doesn't seem to be the case. For example: <body> <form style='background-color:red'> <input type='text' style='background-color:green;display:block;width:auto'> </form> </body> Two questions then: Is there a definition of exactly what width:auto does mean? The CSS spec seems vague to me, but maybe I missed the relevant section. Is there a way to achieve my expected behaviour for a input field - ie. fill available space like other block level elements do? Thanks!

• Word 2010 doc skips pages

  - by Sarah

  A Word document with 9 pages, 3 section brakes next page (no odd and even breaks used) and inserted page numbers shows the correct sequence of pages when moving thru the document. When I change the page numbers in section 2 to start from 1 (Section 1 is only one page numbered with a roman numeral.) Then two strange things happen: The sequence in the status bar goes from 1 to 3. Page 2 disappeared (no text is missing) and my total number of pages reads 10 when i actually only have 9. The first page has a table of contents. Page 2 is listed, but when I press ctrl + click the shortcut it goes to page 4?

• Windows always logs in to temporary profile (thinks it is in D while it is in C)

  - by asdf

  I have Windows on C: Disk 0 Partition 1 When I start it works fine until the login screen. When I log in, it starts to display "preparing your desktop.." and logs in to a temporary profile. I have to run explorer.exe manually then using task manager. If I execute %SystemRoot% it tells me that Windows could not find D:\Windows. (while Windows is in C:) I have no such drive as D then why Windows is thinking it is in D? I've tried this Bootmanager is missing but it did not work. Bootrec /ScanOS from Windows setup gives me Total identified Windows installations: 0 Also note that Windows Setup correctly thinks windows is installed on C but Windows itself thinks it is on D.

• Explode URL Query String Issue

  - by Ian McAbee

  PHP newbie here.. I am trying to create a function where the user is redirected back to the previous page after adding an item to their cart. However, when they are redirected back with the code below it leaves a duplicate of the directory (ie. example.com/catalog/garden-tools/garden-tools function custom_add_to_cart_redirect() { $_SERVER['REQUEST_URI_PATH'] = parse_url($_SERVER['REQUEST_URI'], PHP_URL_PATH); $url = explode('/', rtrim($_SERVER['REQUEST_URI_PATH'], '/')); return $url[3]; } A print_r reveals the following: Array ( [0] => [1] => thefarmshop [2] => catalog [3] => garden-tools [4] => gardening-glove ) What could the issue be?

• Debugging PHP in Aptana 2.0

  - by Nick Lowman

  I'm a real newbie when it comes to PHP debugging so forgive my stupidity. I have a simple html form that submits to a PHP script and I want to debug that script and see what's being sent from the form. My Aptana has two two PHP interpreters installed; Zend Debugger on port 10001 and XDebug on 9000 I have the Firefox Aptana Addon installed I have my HTML page on the following url, running locally; http://3i/latest.html In the IDE I open the PHP script and add some breakpoints, I then open the latest.html and I click on the debug button. It launches the HTML page in a local webserver running at; http://127.0.0.1:8000/3i/latest.html I then fill out the form and submit at which point the debugger tells me the JS Debugger has terminated but it doesn't stop at my break points. I've had a good read around and I can't find anything which helps me, which makes me think it's something pretty easy and I'm being a bit dumb.

• Can anyone recommend free network monitoring tools?

  - by Josamoto

  Hi all I have a machine at home on a 3G internet connection, and my PC is consuming approximately about 200MB per day in uploads & downloads. I'm using an application called Networx to monitor the upload/download usage, but I am on the outlook for the culprit application munching away on my cap. Networx tells me how much my connection uses in total, and I need to know how much each application uploaded / downloaded. Does anyone know of a network connection monitoring utility for Windows 7 that can give me a daily outline of how much data was uploaded & downloaded, and specify this on a PER APPLICATION basis. Thanks in advance!

• 1024x768 gone (1024x600 availble) on HDMI, yesterday it worked?

  - by Gam Erix

  When I try to play a game called F-22 Total Air War 2.0 I get an error which says that the resolution 1024.768 is unsupported by the harware.. so I look into my desktop options and it looks like there is an option for 800x600, 1024x600, 1152x648 and higher wide screen resolutions but the 1024x768 is gone? I did play the game yezterday, I disconnected the HDMI, got upstairs, played a few more games, came back downstairs, plugged in the HDMI, launched the game and bam I got the error! I have a ATI Radeon Mobility HD5470 and the newest ATI Catalyst Center downloaded 3 days ago. How can I 'enable' the 1024x768 resolution again? Without it I can't play the game on my Big TV and I will be stuck with my little laptop screen.

• Is it possible to analyze the size of a SubVersion repository?

  - by BrianH

  Is it possible to know how much disk space each project in a SubVersion repository is using? I can check out a working copy of each project and look at the size each project takes up, but I don't think that encompasses the total size of the project (all revisions). I can look under the "db" directory of the repository, but none of the files in there make sense - I don't think it is possible to use them to figure out how much space each project occupies. I tried the svn ls --verbose command, but the size that it gives me is just the size of the actual files in the head revision, I don't think it includes all revisions. Maybe this isn't possible, but I thought I would ask. Thanks in advance!

• Rails Routes Mappings

  - by rdasxy

  I'm a rails newbie, and I have a controller called resource_links that I've mapped to resources: resources :resources, :as => :resource_links, :controller => :resource_links And this works (basically /resources works as /resource_links). However, trying to go to /resources/tags does not work. To get around this, I added more mappings as: match 'resource_links/tag/:tag(.:format)' => 'resource_links#tag', :via => :get, :as => 'resource_links_tagged', :constraints => {:tag => /.*/} match 'resource_links/tags' => 'resource_links#tags', :via => :get, :as => 'resource_links_tags' Is there any way I can get /resources/tags to be mapped to /resource_links/tag?
