• Hook to make Subversion Read Only for specific users

  - by Shane

  We have an existing Subversion repository that uses LDAP to manage users/passwords. There are some new users who we would like to provide read-only access to SVN. I did some Google searches and found a way to open up read-only access to anonymous users, but this is not what we want. We do not want to open up SVN to everyone. We still want to control login through LDAP, but we would like to prevent certain named users from being able to add/edit/delete. I am assuming this can be done with a hook (pre-commit?), but I have no experience writing hooks. Can someone show me or point me to an example of how to do this?

• MS SQL Query Question

  - by Lp1

  Running MS SQL 2008, and I am definitely a new SQL user. I have a table that has 4 columns: EmpNum, User, Action, Updatetime A user logs into, and out of a system, it is registered in the database. For example, if user1 logs into the system, then out 5 minutes later, a simple query (select * from update) would look like: EmpNum User Action Updatetime 1 User1 I 2010-01-01 23:00:00:000 1 User1 O 2010-01-01 23:05:00:000 I'm trying to query the Empnum, User, Action, I(in time), O(out time), and the total time. Any help or a point in the right direction, and I would be eternally grateful. :)

• How do I stop setNeedsDisplayInRect / drawRect coalescence?

  - by No One in Particular

  When programming my app, I get to the point where I have to update two rectangles on the screen. So I call [self setNeedsDisplayInRect:rect1] and then [self setNeedsDisplayInRect:rect2]. When my drawRect method is called, the rectangle parameter is the smallest rectangle which contains both rect1 and rect2. I can handle this with no problem, but when the two rectangles are far apart, then I am updating a lot of real estate with no gain. In this case, I would just like to repaint my two small rectangles. So my question is how can I prevent the underlying system from coalescing my two calls into one?

• Runtime Error in asp.net site?

  - by Surya sasidhar

  hi, I developed a website in asp.net and i place the site in online. I upload my site in online by using CuteFTP. After uploading when i type my url it is giving error like this... Description: An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed remotely (for security reasons). It could, however, be viewed by browsers running on the local server machine. Details: To enable the details of this specific error message to be viewable on remote machines, please create a tag within a "web.config" configuration file located in the root directory of the current web application. This tag should then have its "mode" attribute set to "Off". Notes: The current error page you are seeing can be replaced by a custom error page by modifying the "defaultRedirect" attribute of the application's configuration tag to point to a custom error page URL.

• After C++ - Python or Java?

  - by carleeto

  I'm fast approaching the point in my coding where I would like to quickly write object oriented code in languages other than C++ for a variety of reasons. After a lot of research, my choices have pretty much narrowed down to Python and Java. I'm leaning towards Python because of its relationship to C, but with Java, from what I can see, I get a good introduction to using and creating test suites with Eclipse - there is also Processing which is pulling me towards Java. I'm not the kind of guy to tackle two languages at once, so which one would you recommend and why? What I want at the end is to have an additional language I can use for rapid development. Ease of learning isn't important to me as I'm willing to put in the time regardless. Ability to use the new language widely is.

• Question about a dialog form and submit errors

  - by user248959

  Hi, I have the link below that executes the action message/new which shows a form inside a jqueryui modal dialog. <div id="myDialog"> </div> echo jq_link_to_remote('Enviar mensaje', array( 'url' => 'mensaje/new?receptor='.$miembro->getId().'&tipo=0&estado=0', 'update' => 'myDialog', 'complete' => "jQuery('#myDialog').dialog({ width:375, height:220, top:123, resizable:false, modal:true, autoOpen: false }); jQuery('#myDialog').dialog('open')" )); The point: if there are submit errors the form is not showed inside the dialog form but in a empty page (mensaje/create).. Any idea? Javi

• Is there a slick way to deploy my silverlight app and change settings programmatically?

  - by MIke S.

  I am fairly new to web development. I am at the point of deployment (for testing). I have a few places (maybe 4 places) where I had to add a URI that was non-relative into the appliation. So now, at deployment, those need to be changed. Is there a slick way of handling this? By slick I mean not manually going through the app and changing the URIs or a blanket find and replace (too risky). I only have 4 places to change now, but this could easily change and cause deployment issues. I am using a Microsoft technology stack. Silverlight, ASP.NET, RIA, etc. Development is done in Visual Studio 2010. I noticed that the web projects have a nifty transformation for the web.config...which is nice. Is there an equivalent mechanism for silverlight resources? Any other ways? Any thoughts?

• How can I set breakpoints in an external JS script in Firebug

  - by Manu

  I can easily set breakpoints in embedded JS functions, but I don't see any way of accessing extarnal JS scripts via Firebug unless I happen to enter them during a debug session. Is there a way to do this w/o having to 'explore' my way into the script? @Jason: This is a good point, but in my case I do not have easy access to the script. I am specifically talking about the client scripts which are invoked by the ASP.Net Validators that I would like to debug. I can access them during a debug session through entering the function calls, but I could not find a way to access them directly.

• Creating attribute sets and attributes programatically magento

  - by digital_paki

  I am using the code listed on the following link =: http://www.magentocommerce.com/wiki/5_-_modules_and_development/catalog/programmatically_adding_attributes_and_attribute_sets Everything works until the point: // Just add a default group. else { $this->logInfo("Creating default group [{$this->groupName}] for set."); $modelGroup = Mage::getModel('eav/entity_attribute_group'); $modelGroup->setAttributeGroupName($this->groupName); $modelGroup->setAttributeSetId($id); // This is optional, and just a sorting index in the case of // multiple groups. // $modelGroup->setSortOrder(1); $model->setGroups(array($modelGroup)); } I am unsure where the object reference would need to be set from - I am attempting to have this as a separate file that can be automated - I am running this file by doing a require_once 'app/Mage.php'; Mage::app(); Any help in this would be greatly appreciated Thanks

• PHP OOP: Unique method per argument type?

  - by sunwukung

  I'm writing a little homebrew ORM (academic interest). I'm trying to adhere to the TDD concept as a training exercise, and as part of that exercise I'm writing documentation for the API as I develop the class. Case in point - I'm working on a classic "getCollection" type mapper class. I want it to be able to retrieve collections of asset X (let's say blog posts) for a specific user, and also collections based on an arbitrary array of numeric values. So - you might have a method like any one of these $User = $UserMapper->load(1); $ArticleCollection = $ArticleMapper->getCollection(range(10,20)); $ArticleCollection = $ArticleMapper->getCollection($User); $ArticleCollection = $ArticleMapper->getCollection($User->getId()); So, in writing the documentation for the getCollection method - I want to declare the @param variable in the Docblock. Is it better to have a unique method for each argument type, or is it acceptable to have a method that delegates to the correct internal method/class based on argument type?

• Windows Server 2003

  - by user229133

  I have a website that is using Windows Server 2003. The site is called https://mysite.com/ and at ip address 111.1.1.1. Now when I log into the site all my relative links that are generated using NavURL (<%# NavURL("Images/Menu/img.gif")%) are saying "http://111.1.1.1/Images/Menu/img.gif" instead of "https://mysite.com/Images/Menu/img.gif". This is causing an error because it needs to be secure. I'm sure there is a setting on the server somewhere to point to the name and not the ip, but I don't know where. Thanks for your help.

• MySQL - Where - search string - MATCH.

  - by Jamie

  Hi guys, Quick question. I'm in a bit of a rush but if someone could quickly point me in the right direction I would be very very happy. I have a field in the db, let's call it field_a which returns a string in the format "20,50,60,80" etc. I wish to do a query which will search in this field to see if 20 exists. Could I use MySQL MATCH or is there a better way? Thank you!

• openCV center of image rotation in C

  I want to rotate 90 degrees counterclockwise, but it seems the rotation point is wrong. How do I find the rotation center of the source image? img=cvLoadImage(argv[1],-1); height = img->height; width = img->width; step = img->widthStep; channels = img->nChannels; data = (uchar *)img->imageData; IplImage *rotatedImg = cvCreateImage(cvSize(height,width), IPL_DEPTH_8U,img->nChannels); CvPoint2D32f center; center.x = width/2; center.y = height/2; CvMat *mapMatrix = cvCreateMat( 2, 3, CV_32FC1 ); cv2DRotationMatrix(center, 90, 1.0, mapMatrix); cvWarpAffine(img, rotatedImg, mapMatrix, CV_INTER_LINEAR + CV_WARP_FILL_OUTLIERS, cvScalarAll(0)); cvShowImage("My image", rotatedImg );

• Git svn - no changes, no branches (except master), rebase/info is not working

  - by ex3v

  I know that similar questions were asked before, but I think my is a little bit different, so please don't point me to existing threads. I'm migrating our old svn repo to git. I did git svn clone path --authors-file abc.txt and everything seemend legit to me. Then I did git remote add origin xyz and git push --all origin and it also worked. I created this repo as test one, with only me having access to both local repo and origin. No changes were made in project held on this repo, nothing to commit, no pushing and so on. There is also only one branch, because someone initialized svn years ago without creating proper folder structure (branches, trunk, tags). Meanwhile someone pushed their work to svn, so I tried to git svn fetch (which worked), and git svn rebase which didn't, giving me error: Unable to determine upstream SVN information from working tree history Is there any reason why git svn decided to stop working?

• Cross domain XMLHttpRequest in classic ASP

  - by HahaHehe

  My code is working fine till i migrate it to another server with firewall. After since, some part of my code is not working. Its seem to be the xmlhttp POST problem. Can someone point me to the right direction and how to determine if the firewall is the problem. My client insisted to me to use classic asp, so i cannot upgrade to .net. Dim objHttp SUBMIT_URL = "http://www.abc.com/confirm.asp" Call Process() Public Sub Process() set objHttp = Server.CreateObject("Microsoft.XMLHTTP") 'set the timeout values in milliseconds lResolve = 1 * 1000 lConnect = 1 * 1000 lSend = 2 * 1000 lReceive = 2 * 1000 objHttp.open "POST", SUBMIT_URL, false objHttp.setRequestHeader "Content-type", "application/x-www-form-urlencoded" objHttp.Send str if err.number <> 0 then Response.Write "Error : " & err.Description err.Clear end if End Sub

• Rscript does not recognize setGeneric function

  - by Branko K.

  I am trying to convert an R script into something that a client can run in batch mode. My code uses generic functions and one snippet which is near the beginning goes like: setGeneric("testInput", function(inputData, params = list()) standardGeneric("testInput")) I've been using R CMD BATCH and it works fine. However I couldn't find an easy way to make my script print the output on the console, so based on that (and suggestion that Rscript.exe is the "proper" way to run R batch files) I decided to switch to Rscript. However when running the very same .R file with Rscript I get the following: Error: could not find function "setGeneric" Execution halted I know there is probably a trivial reason behind this but I just cannot figure it out. Can someone please point me to where the mistake is? Thanks so much in advance. Cheers!

• How to read binary column in database into image on asp.net page?

• MySQL UpdateXML with automatic node inserting?

  - by JimPsr

  I am writing an application that supports custom fields. Currently I store all custom fields in a XML formated text field ( e.g. '<root><field1>val1</field1><field2>val2</field2></root>' in cust_field) I am able to to use updateXML(cust_field, '/root/field1', '<field1>new value</field1') to update those values, however if I use updateXML(cust_field, '/root/field3', '<field3>new value</field3>') then it does not work since field3 is not in the old value. Is there a way to let MySQL automatically insert the new field3 node and its value into cust_field? I am thinking about stored procedure or even stored function but not familiar with both, can anyone point me to the right direction?

• Overhead of serving pages - JSPs vs. PHP vs. ASPXs vs. C

  - by John Shedletsky

  I am interested in writing my own internet ad server. I want to serve billions of impressions with as little hardware possible. Which server-side technologies are best suited for this task? I am asking about the relative overhead of serving my ad pages as either pages rendered by PHP, or Java, or .net, or coding Http responses directly in C and writing some multi-socket IO monster to serve requests (I assume this one wins, but if my assumption is wrong, that would actually be most interesting). Obviously all the most efficient optimizations are done at the algorithm level, but I figure there has got to be some speed differences at the end of the day that makes one method of serving ads better than another. How much overhead does something like apache or IIS introduce? There's got to be a ton of extra junk in there I don't need. At some point I guess this is more a question of which platform/language combo is best suited - please excuse the in-adroitly posed question, hopefully you understand what I am trying to get at.

• mod_rewrite with GET requests

  - by iMaster

  I have mod_rewrite working on most of my site. Right now I have a search that normally would point to search.php?keyword=KEYWORD And I'm trying to rewrite that to search/?keyword=KEYWORD Just to make it a little bit cleaner. So here's my mod_rewrite. (There are other rules I'm just posting the one that isn't working.) RewriteRule ^search/?keyword=([^/\.]+)/?$ search.php?search=$1 When I type a search in the address bar way I want it to be, I get a page telling me its a "broken link" (I'm guessing that that's Chrome's equivalent of a 404 error). So what am I doing wrong? I think that the problem is the '=' or the '?' sign in the rule (the first part) because when I take the ?keyword= part out, it works. Does that make sense?

• C# Balloon Notification Popup over all other apps

  - by user1114503

  I have a balloon popup (from a notifyIcon) in C# that works perfectly, unless there is a fullscreen application on the users monitor, such as a power point presentation. In that case, the popup doesn't show at all. However, once that app exits or is minimized (or the taskbar brought to front) you can see the balloon popups again. Is there a way to make this popup show over all windows? Something like a form's "Top Most" setting? My code for the balloon is below if anyone needs it. notifyIcon1.BalloonTipText = "Issue found!"; notifyIcon1.ShowBalloonTip(5000); Thank you!

• How to use SynonymFilterFactory in Solr?

  - by AlxVallejo

  I'm trying to execute synonym filtering at query time so that if I search for X, results for Y also show up. I go to where Solr is being run, edit the .txt file and add X, Y on a new line. This does not work. I check the schema and I see: <analyzer type="query"> <filter class="solr.SynonymFilterFactory" synonyms="synonyms.txt" ignoreCase="true" expand="true" /> What am I missing? EDIT Assessing configuration files tomcat6/Catalina/localhost seems to point to the correct location <Context docBase="/data/solr/solr.war" debug="0" privileged="true" allowLinking="true" crossContext="true"> <Environment name="solr/home" type="java.lang.String" value="/data/solr" override="true" /> </Context> Also, in the Solr admin I see this. What does cwd mean? cwd=/usr/share/tomcat6 SolrHome=/data/solr/

• javascript pop-up menu help

  - by baiano

  I am working on a project similar to a table where the user will be able to add rows. Right now there is just one row type available but I would like to give the user the ability to select from a list without changing the layout of the page. So, I put together a menu that appears on mouseover of the 'add row' link and disappears on mouseout (with a slight delay and fade in/out) using mootools event listeners. It looks like: I am now trying to figure out an easy way to make it so that the list stays available when the user's mouse leaves the 'add a row' link to go to select an item from the list. I looked through various mootools add-ons and tutorial but didn't find anything all that helpful. Does anyone know of a good tutorial guide me through this or can otherwise point me in the right direction here?

• How to see full compile path in Eclipse?

  - by alleywayjack

  I have looked for an answer for this nearly every where that I can think of, but there doesn't seem to be any way to actually SEE what Eclipse "runs" to compile the projects (as it does need the JDK installed and visible to actually build). I ask because I imported a few jars into my project, and even though I've looked through all the javac documentation, I can't seem to figure out how to mimic it quite like Eclipse does. I really, really need to be able to compile on the command line in this case - Eclipse or any other IDE just isn't what is needed. I started to look through the Eclipse source, and although this sounds lazy, I just became overwhelmed and figured I would ask here first, hoping someone else had the same question at one point.
