  • MongoMapper, Rails, Increment Works in Console but not Controller

    - by Michael Waxman
    I'm using mongo_mapper 0.7.5 and rails 2.3.8, and I have an instance method that works in my console, but not in the controller of my actual app. I have no idea why this is. #controller if @friendship.save user1.add_friend(user2) ... #model ... key :friends_count, Integer, :default => 0 key :followers_count, Integer, :default => 0 def add_friend(user) ... self.increment(:friends_count => 1) user.increment(:followers_count => 1) true end And this works in the console, but in the controller it does not change the follower count, only the friends count. What gives? The only thing I can even think of is that the way that I'm passing the user in is the problem, but I'm not sure how to fix it.

  • Need to compare blobs in firebird

    - by Michael Beck
    Hey guys, I need to check on the contents of blobs in my databases (yes, plural, but one problem at a time). In one database, I have about 900 images of potentially varying sizes. I need to check to see if the versioning system that's built into our application is actually correctly replicating the image data from the previous version to the new version of a record. How do I compare values en masse so I don't have to pick through each record one at a time and open up the blob using FlameRobin or Firebird Maestro and visually compare these images? Thanks for any assistance.

  • How to connect 3 monitors into an Asus 9800GT

    - by aliasbody
    I don't know if this is possible but, I've heard that there exist some DVI connections that allow and recognize the connection os 2 Monitores in the same port (I can be wrong tho). I have an Asus 9800GT 512MB on my computer that runs Ubuntu 12.04 and Arch Linux, and I am trying to connect 3 monitors. I already have 2 (17" each), and want to connect a new one with 19", but on my 9800GT I only have 2 DVI connections. Is there anyway to have 3 monitores extended without having to buy a new GPU ? Thanks in Advance,

    I'm trying to set up a test LDAP-server for some developers but I'm running into some trouble. service slapd start errors so I run /usr/sbin/slapd -d 1 and this gives me the following error at the end: unable to open pid file "/var/run/ldap/slapd.pid": 13 (Permission denied) slapd destroy: freeing system resources. slapd stopped.

  • When using Bundler and Rails 2.3.5 I get uninitialized constant SubdomainFu when migrating

  • Django - testing using large tables of static data

    - by Michael B
    I am using "manage.py test" along with a JSON fixture I created using using 'dumpdata' My problem is that several of the tables in the fixture are very large (for example one containing the names of all cities in the US) which makes running a test incredibly slow. Seeing as several of these tables are never modified by the program (eg - the city names will never need to be modified), it doesn't make much sense to create and tear down these tables for every test run. Is there a better way to be testing this code using this kind of data?

    I'm horribly failing at exporting Exchnange Mailboxes to PST files. Perhaps You are able to help me? The System I'm running some legacy machines here.

But after running the command an error occurs (I'm sorry, it is the german version of Windows 2008 - but if you translate Fehler with error and Vorgang with process you should be prepared enough to go ;)) [PS] C:\Export-Mailbox -Identity marco -PSTFolderPath C:\ExchangeExport Fehler für Marco S ([email protected]).

  • Is it possible to use a laptop charger in other laptop with different specifications?

    - by poz2k4444
    Let's say I have my laptop charger that uses 19.5V and 3.9A and I want to use it in other laptop that has no charger but it needs just 19V and 3.16A, I've studied a little of electtronics and I know that the amperage doesn't affect because the computer will use just the necessary, but I'm not really sure about the voltage. I read this post and I know the polarity is the same and the connector fits, but it doesn't say anything about voltage, I also know if the voltage of the charger were lower than the specification it'll not be a problem, but what about this little almost insignificant difference??

  • Question with R. Element wise multiplication, addition, and division with 2 data.frames with varying

    - by Michael
    I have a various data.frames with columns of the same length where I am trying to multiple 2 rows together element-wise and then sum this up. For example, below are two vectors I would like to perform this operation with. > a.1[186,] q01_a q01_b q01_c q01_d q01_e q01_f q01_g q01_h q01_i q01_j q01_k q01_l q01_m 3 3 3 3 2 2 2 3 1 NA NA 2 2 and > u.1[186,] q04_avl_a q04_avl_b q04_avl_c q04_avl_d q04_avl_e q04_avl_f q04_avl_g q04_avl_h q04_avl_i q04_avl_j q04_avl_k q04_avl_l q04_avl_m 4 2 3 4 3 4 4 4 3 4 3 3 3` The issue is that various rows have varying numbers of NA's. What I would like to do is skip the multiplication with any missing values ( the 10th and 11th position from my above example), and then after the addition divide by the number of elements that were multiplied (11 from the above example). Most rows are complete and would just be multiplied by 13. Thank you!

  • Postfix SMTP server down on Ubuntu

    I have a Plesk server running Postfix on Ubuntu 10.04 and the SMTP service on port 25 is down. When I stop and then start postfix the server comes up only for a minute and goes down again. I have checked the load on the server and it is low as shown: *top - 04:29:33 up 19 days, 3:25, 4 users, load average: 1.47, 1.78, 2.34 Tasks: 936 total, 1 running, 935 sleeping, 0 stopped, 0 zombie Cpu(s): 0.7%us, 0.3%sy, 0.0%ni, 86.6%id, 11.7%wa, 0.6%hi, 0.1%si, 0.0%st Mem: 6110496k total, 6072988k used, 37508k free, 251244k buffers Swap: 12000544k total, 95264k used, 11905280k free, 4370432k cached* IMAP clients are not experiencing a problem and there are no issues with receiving emails for both POP or IMAP.

  • Perl : get substring which matches regex error

    - by Michael Mao
    I am very new to Perl, so please bear with my simple question: Here is the sample output: Most successful agents in the Emarket climate are (in order of success): 1. agent10896761 ($-8008) 2. flightsandroomsonly ($-10102) 3. agent10479475hv ($-10663) Most successful agents in the Emarket climate are (in order of success): 1. agent10896761 ($-7142) 2. agent10479475hv ($-8982) 3. flightsandroomsonly ($-9124) I am interested only in agent names as well as their corresponding balances, so I am hoping to get the following output: agent10896761 -8008 flightsandroomsonly -10102 agent10479475hv -10663 agent10896761 -7142 agent10479475hv -8982 flightsandroomsonly -9124 For later processes. This is the code I've got so far: #!/usr/bin/perl -w open(MYINPUTFILE, $ARGV[0]); while(<MYINPUTFILE>) { my($line) = $_; chomp($line); # regex match test if($line =~ m/agent10479475/) { if($line =~ m/($-[0-9]+)/) { print "$1\n"; } } if($line =~ m/flightsandroomsonly/) { print "$line\n"; } } The second regex match has nothing wrong, 'cause that is printing out the whole line. However, for the first regex match, I've got some other output such like: $ ./compareResults.pl 3.txt 2. flightsandroomsonly ($-10102) 0479475 0479475 3. flightsandroomsonly ($-9124) 1. flightsandroomsonly ($-8053) 0479475 1. flightsandroomsonly ($-6126) 0479475 If I "escape" the braces like this if($line =~ m/\($-[0-9]+\)/) { print "$1\n"; } Then there is never a match for the first regex... So I'm stuck with a problem of making that particular regex work. Any hints for this? Many thanks in advance.

  • onmouseover with django / imagekit

    - by Michael Moreno
    I'm using Imagekit. View.py includes: def pics(request): p = Photo.objects.all() return render_to_response('Shots.html', {'p': p}) The following simple code in the template will generate associated images: {% for p in p %} <img src = "{{ p.display.url }}"> <img src = "{{ p.thumbnail_image.url }}"> {% endfor %} I'm attempting to generate a series of thumbnails {{ p.thumbnail_image.url }} which, when mouseover'd, will generate the slightly larger version of the image, {{ p.display.url }} via Javascript. The following code in the template attempts to do so: <html> <head> <HEAD> <script language="Javascript"> { image1 = new Image image2 = new Image image1.src = {{ p.thumbnail_image.url }} image2.src = {{ p.display.url }} </script> </head> <body> {% for p in p %} <a href="" onMouseOver="document.rollover.src= image2.src onMouseOut="document.rollover.src= image1.src"> <img src="{{ p.thumbnail_image.url }}" border=0 name="rollover"></a> {% endfor %} </body> </html> This will display the series of thumbnails, but the larger image will not display when mouseover'd. I believe it has to do with how I'm specifying the variable {{ p.display.url }}.

  • ClickOnce Deployment Error - Access to the Path is Denied

    - by michael.lukatchik
    I have a WPF app that I'm deploying to a network path using ClickOnce deployment. After the app is deployed to a network location, I use the ClickOnce html page to launch the installation process. I am successfully able to download and install the app. However, my users are not able to download and install the app. When a user navigates to the ClickOnce html page and clicks to begin the installation process, the following error message is received: ERROR SUMMARY Below is a summary of the errors, details of these errors are listed later in the log. * Activation of http://software.mycompany.com/myapp/myapp.application resulted in exception. Following failure messages were detected: + Downloading file://dev/webs/software/myapp/myapp.application did not succeed. * [4/5/2010 1:56:59 PM] System.Deployment.Application.DeploymentDownloadException (Unknown subtype) - Downloading file://dev/Webs/software/myapp/myapp.application did not succeed. All signs point to this being a security issue. So, I've done the following: Ensured that "Everyone" had read access to the files that were being deployed as part of my project Ensured that "Everyone" had read access to the network location where the app was deployed (//dev/webs/software/myapp) Ensured that "Everyone" had read access to the IIS path where the ClickOnce html page is located In each of these cases, I've made no progress in getting the app to successfully deploy via ClickOnce. Again, the odd thing is that I am able to successfully walk through the process of downloading and installing the app. It's my users, though, that need the ability to download and install the app. I've looked extensively on the web for answers, but there hasn't been much. I'd like to resolve the issue without "re-installing" or "rigging" anything. I need a solid answer. Thank you all for your input!! Mike

  • Using ThreadPool.QueueUserWorkItem in ASP.NET in a high traffic scenario

    - by Michael Hart
    I've always been under the impression that using the ThreadPool for (let's say non-critical) short-lived background tasks was considered best practice, even in ASP.NET, but then I came across this article that seems to suggest otherwise - the argument being that you should leave the ThreadPool to deal with ASP.NET related requests. So here's how I've been doing small asynchronous tasks so far: ThreadPool.QueueUserWorkItem(s => PostLog(logEvent)) And the article is suggesting instead to create a thread explicitly, similar to: new Thread(() => PostLog(logEvent)){ IsBackground = true }.Start() The first method has the advantage of being managed and bounded, but there's the potential (if the article is correct) that the background tasks are then vying for threads with ASP.NET request-handlers. The second method frees up the ThreadPool, but at the cost of being unbounded and thus potentially using up too many resources. So my question is, is the advice in the article correct? If your site was getting so much traffic that your ThreadPool was getting full, then is it better to go out-of-band, or would a full ThreadPool imply that you're getting to the limit of your resources anyway, in which case you shouldn't be trying to start your own threads? Clarification: I'm just asking in the scope of small non-critical asynchronous tasks (eg, remote logging), not expensive work items that would require a separate process (in these cases I agree you'll need a more robust solution).

  • $.Post with Form submit

    - by Michael
    ...Some form gets submitted... $.("form").submit(function() { saveFormValues($(this), "./../.."; } function saveFormValues(form, path) { var inputs = getFormData(form); var params = createAction("saveFormData", inputs); var url = path + "/scripts/sessions.php"; $.post(url, params); } The weird thing is that if i add a function to the $.post(url, params, function(data) { alert(data); } I get a blank alert statement. Within scripts/sessions.php i have a function to save whatever the $_POST information is to a file, and the sessions.php never saves this saveFormValues call. It never shows up to the file. But if i keep trying to get it to save, about once every 15 will actually allow it to be saved. This leads me to believe that the forms POST is somehow blocking this value saving post. Any help?

  • /dev/sda1 not a subset of /dev/sda?

    - by Guillaume Brunerie
    Hi, the first entry of my partition table is: $ sudo hexdump -Cv -n 16 -s 446 /dev/sda 000001be 80 01 01 00 83 fe ff ff 3f 00 00 00 81 1c 20 03 |........?..... .| (-Cv describe the output format, -n 16 asks for 16 bytes and -s 446 skips the first 446 bytes) You can see that my first partition is a primary Linux partition and that this partition begin at sector 63 (see for example here for the structure of the partition table). I would then expect that except for the first 63 sectors and the other partitions, /dev/sda1 and /dev/sda are exactly the same. But this is not the case, the sector #2 of /dev/sda1 is not exactly the same as the sector #65 of /dev/sda (but they are very similar, only 16 bytes are different): $ sudo hexdump -Cv -n 512 -s 65b /dev/sda 00008200 00 20 19 00 90 03 64 00 2d 00 05 00 5a 2f 56 00 |. ....d.-...Z/V.| 00008210 b6 b1 16 00 00 00 00 00 02 00 00 00 02 00 00 00 |................| 00008220 00 80 00 00 00 80 00 00 00 20

  • Hudson + Jboss AS 7.1 + Maven 3 Project Build Error

    - by Zehra Gül Çabuk
    I've wanted to prepare an environment that I'm able to build my project and run my tests on a integration server. So I've installed an Jboss application server 7.1 and deployed hudson.war to it. Then I've created a project to trigger "mvn clean install" and when I built it I've got following exception.

So how can I configure the hudson to force it looking at the right place for jars? Is there anyone has an idea? Thanks in advance.

  • Sporadic EXC_BAD_INSTRUCTION (SIGILL) when in 64 bit mode

    For some reason for a low-number of users (say 1 in a few hundred) the application seem to crash when run in 64bit mode on a Snow Leopard 10.6.3 I've attached the code, but please remind IT IS NOT A CODE issue.

Any suggestions other then running the application in 32 bit only? Please do not dilute the feedback by asking for or blaming the code, the code is 100% solid, guaranteed! No memory leaks, the crashes clearly are triggered in 32 bit mode only just after start inside the AppKit itself like deep inside NSThread sleep's callstack.

    Any books you would recommend to learn scripting makefiles? I know gnu.org has manual, but hope there is a book with better explanations and examples.

  • Spatial index for geo coordinates?

    - by Michael Borgwardt
    What kind of data structure could be used for an efficient nearest neighbor search in a large set of geo coordinates? With "regular" spatial index structures like R-Trees that assume planar coordinates, I see two problems (Are there others I have overlooked?): Wraparound at the poles and the International Date Line Distortion of distances near the poles How can these factors be allowed for? I guess the second one could compensated by transforming the coordinates. Can an R-Tree be modified to take wraparound into account? Or are there specialized geo-spatial index structures?

  • How to get --detect-branches to work with git-p4?

    - by Michael Brennan
    My p4 repository has a structure similar to: //depot/project/branch1 //depot/project/branch2 //depot/project/branch3 ... etc However, when I use git-p4 to clone "project", all 3 branches are not considered as branches and all get cloned into the single master branch. This is how I'm invoking git-p4: git-p4 clone --detect-branches //depot/project I was expecting git-p4 to create a git database for "project" with three branches, and the root of the project would be mapped to the portion of the path after the branch name (for example: if //depot/project/branch1 has a subdirectory called "lib" (//depot/project/branch1/lib) then my local file system should be something like /git_project/lib with 3 git branches). Is what I'm expecting wrong? Am I invoking git-p4 incorrectly?

  • JNDI / Classpath problem in glassfish

    - by Michael Borgwardt
    I am in the process of converting a large J2EE app from EJB 2 to EJB 3 (all stateless session beans, using glassfish 2.1.1), and running out of ideas. The first EJB I converted (let's call it Foo) ran without major problems (it was the only one in its ejb-module and I could completely replace the deployment descriptor with annotations) and the app ran fine. But after converting the second one (let's call it Bar, one of several in a different ejb-module) there is a weird combination of problems: The app deploys without errors (nothing in the logs either) There is an error when looking up Bar via JNDI When looking at the JNDI tree in the glassfish admin console, Bar is not present at all. Then when I look at the logs, I see this (Foo is the correct name of the EJB's remote interface of the first converted, previously working EJB): Caused by: javax.naming.NamingException: ejb ref resolution error for remote business interface Foo [Root exception is java.lang.ClassNotFoundException: Foo] at com.sun.ejb.EJBUtils.lookupRemote30BusinessObject(EJBUtils.java:425) at com.sun.ejb.containers.RemoteBusinessObjectFactory.getObjectInstance(RemoteBusinessObjectFactory.java:74) at javax.naming.spi.NamingManager.getObjectInstance(NamingManager.java:304) at com.sun.enterprise.naming.SerialContext.lookup(SerialContext.java:414) at com.sun.enterprise.naming.SerialContext.list(SerialContext.java:603) at javax.naming.InitialContext.list(InitialContext.java:395) at com.sun.enterprise.admin.monitor.jndi.JndiMBeanHelper.getJndiEntriesByContextPath(JndiMBeanHelper.java:106) at com.sun.enterprise.admin.monitor.jndi.JndiMBeanImpl.getNames(JndiMBeanImpl.java:231) ... 68 more Caused by: java.lang.ClassNotFoundException: XXX at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1578) at com.sun.ejb.EJBUtils.getBusinessIntfClassLoader(EJBUtils.java:679) at com.sun.ejb.EJBUtils.lookupRemote30BusinessObject(EJBUtils.java:348) ... 75 more This is followed by more exceptions for all the entries that (like Foo) do appear in the JNDI tree. These look like this: Caused by: javax.naming.NotContextException: BarHome cannot be listed at com.sun.enterprise.naming.SerialContext.list(SerialContext.java:607) at javax.naming.InitialContext.list(InitialContext.java:395) at com.sun.enterprise.admin.monitor.jndi.JndiMBeanHelper.getJndiEntriesByContextPath(JndiMBeanHelper.java:106) at com.sun.enterprise.admin.monitor.jndi.JndiMBeanImpl.getNames(JndiMBeanImpl.java:231) ... 68 more However, no exception for Bar, it does not appear in the log at all except one entry during deployment. The other EJBs in the same module do appear, as does Foo. Any ideas what could cause this or how to diagnose it further? The beans are pretty straightforward: @Stateless(name = "Foo") @RolesAllowed("FOOUSER") @TransactionAttribute(TransactionAttributeType.SUPPORTS) public class FooImpl extends BaseBean implements Foo { I'm also having some problems with the deployment descriptor for Bar (I'd like to eliminate it, but glassfish doesn't seem to like having a bean appear only in sun-ejb-jar.xml, or having some beans in a module declared in the descriptor and others use only annotations), but I can't see how that could cause the ClassNotFoundException on Foo. Is there a way to see the ClassPath that Glassfish is actually using?
