• Crontab - stop sending mail, special case ||

  - by 2ge

  Hi all, I need to put into my crontab small command, which is checking, if lighttpd web server is running, for some reason it hangups sometimes. So I got there: * * * * * root /bin/pgrep lighttpd || /usr/local/etc/rc.d/lighttpd restart >/dev/null 2>&1 problem is, this send me mail every minute, in the mail is number of PID of lighttpd, which is running. For other crontab job, redirection work, so I assume, when is there "||", it makes problem. maybe there should be better to rewrite crontab job, so it uses exit status of pgrep, so I can avoid "||". I am using FreeBSD. Thanks for any help, for now I disabled this job

• Setting up path mapping in PHP and Eclipse

  - by jax

  I have just setup my website locally so I can test my pages more easily. Eclipse has been configured to use an XAMPP server locally. The problem is that I want to map my project to a certain place in my website. ie. In my Eclipse PHP project I have a folder called com I want this to map to /com in the webstie. I tried to do this in the mapping section of the Eclipse server setup but it didn't work. When I type http://localhost/com/ It should go to my project folder, however, when I type other folder it should use the normal website folders. how can I do this?

• Log4net appender filename issue

  - by JL

  I have an appender setup like this <appender name="Scheduler_Appender" type="log4net.Appender.RollingFileAppender"> <file value="c:\temp\ApplicationLog.txt"/> <rollingStyle value="Date"/> <datePattern value="yyyyMMdd"/> <appendToFile value="true"/> <staticLogFileName value="true"/> <layout type="MinLayout"> <locationInfo value="true"/> </layout> </appender> When the log file first gets created the file name is simply ApplicationLog.txt this is correct. However when the logging rolls - the filename that gets generated is ApplicationLog.txt20100323 (for example), and not ApplicationLog20100323.txt How can I change the configuration so files are rolled to [FileName][Date].[ext] rather than [FileName].[ext][Date] Thanks

• block access to certain website types

  - by frustrated teacher

  Need to block access to certain website types without listing each URL to block. Students at secondary school are going to porn sites. Need to be able to block all such access without having to list each possible site URL. Having the Content -- Ratings tab set to None for all categories on the ratings files listed on my computers does not prevent access. Unchecking users may access sites with no rating, even with the security settings set to High, still allows the porn sites to come up. If that is checked, then ONLY listed sites can open and students would not be able to do any research via google, for example. I would rather not have to continue checking each computer and blocking sites as they find them.

• Anonymous method as function result

  - by iamjoosy

  What I want to do is to assign an anonymous method which I get as a function result to a variable of the same type. Delphi complains about not beeing able to do the assignement. Obviously Delphi things I want to assign the "GetListener" function instead of the result of that same function. Any help with this is very much appreciated. type TPropertyChangedListener = reference to procedure (Sender: TStimulus); TMyClass = class function GetListener:TPropertyChangedListener end; .... var MyClass: TMyClass; Listener: TPropertyChangedListener; begin MyClass:= TMyClass.create; Listener:= MyClass.GetListener; // Delphi compile error: E2010 Incompatible types: TPropertyChangedListener' and 'Procedure of object' end;

• Openlayers and Bing Maps (POLYGONS)

  - by Jordan

  When trying to draw polygons onto a bing map, the initial marker is set differently on the map. How can I fix this? OpenLayers Bing Example <script src="OpenLayers.js"></script> <script> var map; function init(){ map = new OpenLayers.Map("map"); map.addControl(new OpenLayers.Control.LayerSwitcher()); var shaded = new OpenLayers.Layer.VirtualEarth("Shaded", { type: VEMapStyle.Shaded }); var hybrid = new OpenLayers.Layer.VirtualEarth("Hybrid", { type: VEMapStyle.Hybrid }); var aerial = new OpenLayers.Layer.VirtualEarth("Aerial", { type: VEMapStyle.Aerial }); var POLY_LAYER = new OpenLayers.Layer.Vector(); map.addLayers([shaded, hybrid, aerial, POLY_LAYER]); map.setCenter(new OpenLayers.LonLat(-110, 45), 3); var polygon = new OpenLayers.Control.DrawFeature(POLY_LAYER, OpenLayers.Handler.Polygon); map.addControl(polygon); polygon.activate(); } </script> Bing Example <div id="tags"> Bing, Microsoft, Virtual Earth </div> <p id="shortdesc"> Demonstrates the use of Bing layers. </p> <div id="map" class="smallmap"></div> <div id="docs">This example demonstrates the ability to create layers using tiles from Bing maps.</div> Of course the above is being initialized and page works. You can draw the polygon shapes. Notice if you zoom in or out one time, the markers are set at the correct coordinates. My app I was testing this on is really using the bing maps API keys and not VirtualEarth. But it's doing a similar thing. Is this an Openlayers bug? The below source came directly from the open layers example site, I just added and activated polygons to the map. Please let me know how I can fix this for using the Bing Map API.. I've been stuck on this for HOURS! :(

• XML jQuery Problem

  - by Llamabomber

  This code for parsing my xml and appending via jquery seems to work great in every browser but Chrome (Mac only, the windows version of chrome works fine) and explorer. I'm not aware of any glaring issues in the code so I thought some fresh eyes might help. Anyone know what could be causing IE and Chrome on the mac to not append? <script type="text/javascript" charset="utf-8"> $(document).ready(function() { $.ajax({ type: "GET", url: "sitenav.xml", dataType: "xml", success: parseXml }); function parseXml(xml) { $(xml).find("GoogleAnalytics").each(function() { $("li#google_analytics").append('<ul><li>' + $(this).find("NavHeader").text() + '</li></ul>'); }); } }); </script>

• Manually Adjusting UI for Rotation

  - by Driss Zouak

  In my view I have some number-pad type buttons that I want to manually adjust their X and Y when the view is rotated. I'm having trouble figuring out how to support this. I have added in my ViewDidLoad NSNotificationCenter.DefaultCenter.AddObserver("UIDeviceOrientationDidChangeNotification", DeviceRotated ); And I defined my DeviceRotated but the breakpoint is never hit. I thought this might be because of the Autorotate, so I overrided the ShouldAutorotateToInterfaceOrientation and set that to false (true didn't work either). I figured there should be some WillRotate (but that's a void return type) or something that would allow me to indicate that I want the View to rotate, and whatever is set to auto adjust I'd like it to do that, but that I would like to be able to manually adjust any other items that I need. If I have to do everything myself, that's fine as well. Any advice would be appreciated, Driss.

• OS X software updates download but don't install

  - by ridogi

  I've got three 10.6 computers that won't install OS X updates. Checking for new software will show about a dozen updates (Security updates, Safari, iPhoto, printers, etc) and if choose install it downloads them. After downloading and then clicking restart the computer sits at the purplish sky desktop with no progress bar, and then after about 3 minutes it goes back to the login window (without ever installing or restarting). If I then select check for updates the same updates will all be presented and I can repeat the process. Manually downloading and installing an update such as 10.6.8 combo updater works as it should, and then check for updates no longer presents that particular update as an option. This seems to be the result of some setting or 3rd party application as I've got 3 out 7 computers experiencing this exact same problem. What could cause this and how can I fix it?

• controlling the class names generated by JAXB for xsd:attributeGroup?

  - by Stephen Winnall

  I am using JAXB to bind XML to Java for an application that I am writing. I have an element called measure which contains two amount elements called amount and maxAmount, with which I want to model a lower and an upper limiting value. amount and maxAmount are otherwise identical and I would like them to be implemented with the same class when unmarshalled into Java. The following is an extract from the XML schema which I feed to JAXB: <xsd:attributeGroup name="AmountAttributes"> <xsd:attribute name="quantity" type="xsd:decimal"/> <xsd:attribute name="numerator" type="xsd:nonNegativeInteger"/> <xsd:attribute name="denominator" type="xsd:positiveInteger"/> </xsd:attributeGroup> <xsd:element name="measure"> <xsd:complexType> <xsd:sequence> <xsd:element minOccurs="0" name="amount"> <xsd:complexType> <xsd:attributeGroup ref="mpr:AmountAttributes"/> </xsd:complexType> </xsd:element> <xsd:element minOccurs="0" name="maxAmount"> <xsd:complexType> <xsd:attributeGroup ref="mpr:AmountAttributes"/> </xsd:complexType> </xsd:element> </xsd:sequence> </xsd:complexType> </xsd:element> JAXB creates from this a more elaborate version of the following: public class Measure { protected Measure.Amount amount; protected Measure.MaxAmount maxAmount; public static class Measure.Amount {} public static class Measure.MaxAmount {} } Measure.Amount and Measure.MaxAmount are identical except for their names, but - of course - as far as Java is concerned they have little to do with each other. Is there a way of making JAXB use the same class for both amount and maxAmount? Just to come completely clean ;-) I should mention that I generate the XML schema from RNC using Trang. If the answer to the question is "change the XML schema", I have the supplementary question "how do I change the RNC to produce that XML schema?". My RNC looks like this: AmountAttributes = QuantityAttribute? & attribute numerator { xsd:nonNegativeInteger }? & attribute denominator { xsd:positiveInteger }? QuantityAttribute = attribute quantity { xsd:decimal } Measure = element measure { element amount { AmountAttributes }?, element maxAmount { AmountAttributes }? }+ I use RNC because I find it simpler to understand, but if the solution to my problem means just using XML Schema, so be it.

• How do you assign a JavaScript 'onclick' attribute dynamically?

  - by Jack Roscoe

  Hi, I'm creating a button dynamically using JavaScript and at the same time assigning attributes such as 'ID', 'type' etc and also 'onclick' in order to trigger a function. All works fine apart from the assignment of the 'onclick'. When clicked, the button is not triggering the function as it is supposed to. the function I'm trying to run is 'navigate(-1)' as seen below. Where am I going wrong? Here's my code: function loadNavigation() { var backButton; backButton = document.createElement('input'); backButton.ID = 'backButton'; backButton.type = 'button'; backButton.value='Back'; backButton.onclick = 'navigate(-1)'; document.body.appendChild(backButton); }

• How does Amazon ec2-user get its sudo rights

  - by Johan

  I am looking for where the default Amazon AMI linux image sets up the privileges for the default ec2-user account. After logging in with this account I can use sudo successfully. Checking via the sudoers file, which I open by running visudo (with no other options) I see a few default settings and permissions for root ALL ALL So ... Where is the permissions for ec2-user assigned? I have not yet tried to add a new permission but ultimately I want to resign ec2-user for systems management tasks and use a non-full root user for administering the applications (stop and start mysql, httpd, edit apache's vhost files, and upload / edit web content under the web root)

After placing it, I need to resize the frame in order to have that portion completely fit in the frame. Finally, the UIImage should be cropped so that I have a UIImage only displaying the portion that I selected using the frame. Please help me. Regards, Pratik

• boost::enable_if class template method

  I got class with template methods that looks at this: struct undefined {}; template<typename T> struct is_undefined : mpl::false_ {}; template<> struct is_undefined<undefined> : mpl::true_ {}; template<class C> struct foo { template<class F, class V> typename boost::disable_if<is_undefined<C> >::type apply(const F &f, const V &variables) { } template<class F, class V> typename boost::enable_if<is_undefined<C> >::type apply(const F &f, const V &variables) { } }; apparently, both templates are instantiated, resulting in compile time error. is instantiation of template methods different from instantiation of free functions? I have fixed this differently, but I would like to know what is up. Thank you

• A c# Generics question involving Controllers and Repositories

  - by UpTheCreek

  I have a base repository class which contains all the common repository methods (as generic): public abstract class BaseRepository<T, IdType> : IBaseRepository<T, IdType> My repositories from this base e.g.: public class UserRepository : BaseRepository<User, int>, IUserRepository I also have a base controller class containing common actions, and inherit from this in controllers. The repository is injected into this by DI. E.g. public class UserController : BaseController<User> { private readonly IUserRepository userRepository; public UserController (IUserRepository userRepository) { this.userRepository= userRepository; } My question is this: The base controller needs to be able to access the repository methods that are defined in the base repository. However I'm passing in via DI a different repository type for each controller (even though they all inherrit from the base repository). How can the base controller somehow access the repository that is passed in (regardless of what type it is), so that it can access the common base methods?
