• Redirect URL using Mac OS X Server Lion

  - by pheedsta

  I have just set up a Mac Mini with OS X Lion Server to host my own website. I have registered multiple domain names, but I would like the user to be automatically redirected to my main domain name if they type in one of the others (i.e. if the user types in www.myotherdomain.com the URL will be forwarded instantly to www.mymaindomain.com). In the Web settings of Server.app, you can easily add additional domains (which works) but it does not change the URL in the browser to www.mymaindomain.com. It keeps www.myotherdomain.com whilst still displaying the correct pages. Does the redirects or alias options do what I want? I can't seem to work out how to use them (there seems to be no documentation that I can find). In Redirects, you need to enter: 'Redirect Type' (Exact Match or Regular Expression) 'Redirect Path' 'Destination URL' 'Redirect Status' (Original was permanently moved, etc) In Alias, you need to enter: 'Alias Type' (Exact Match or Regular Expression) 'Alias Path' 'Destination Folder' Any help would be great.

• Cannot run setups from a mapped network drive on Windows 7

  - by Dimitri C.

  I'm trying to run an application setup by double-clicking the setup.exe from within Windows Explorer. The file is located on a mapped network drive, and I'm using Windows 7. This results in the following error message: The specified path does not exist. Check the path, and then try again. The workaround I found is to copy the installer to the main hard drive (c:) and run it from there; however, this is rather inconvenient. The same action did work on Windows 2000, Windows XP and Windows Vista. I have the impression that the problem only occurs with installers, as everything seemed to work fine with regular exe's. Is there anyone who can explain this odd behavior?

• Adding an ASP website in IIS7.5 on Windows 7

  - by birdus

  enter preformatted text hereI'm trying to add an ASP website under IIS 7.5 on Windows 7 and am having no luck so far. This site is just for me to hit locally. I need to make some changes to some of the HTML in some of the ASP files and I just need to be able to test my changes as I make them. I installed IIS and checked the box for ASP. Next, I added an Application Pool which I called ASP and which has "No Managed Code" and "ASP" set. Next, I added the website by right-clicking "Sites" then clicking "Add Web Site...". I gave it a name, set it to use the ASP app pool, pointed it to the path where the ASP code is (I left it at pass-through authentication), and typed in 5555 as the port, so as to not interfere with the default website. The code is sitting on my server and the path simply uses the mapped drive that I always use to access files on that drive array. When I type in http://mysite:5555, I get "could not find mysite:5555". I don't really know if all these settings are correct or what else I should try. What am I missing? Thanks, Jay

• Adding multiple gradients to object in Adobe Illustrator

  - by Vass

  Hi, I have an object which is a path (a nose to be specific). Now I want both a linear gradient and a radial gradient to be added to the object. So these must be separate gradient objects I guess, and I can't find a way to add multiple separate gradients to a complete path so do I duplicate the object and then apply a new gradient to each object? And what would the layer transparency features look like? Would the 'normal' overlay of the layers work? I am afraid of multiple shadows creating double dark regions, but maybe that is as its supposed to be if you think in terms of classical art and draw shadows in terms of each light obstruction.

• Ribbon Search: Locate MS Office Ribbon Menu Features/Functions Quickly

  - by Kavitha

  In the new versions of Microsoft Office  everything has changed with the introduction of Ribbon menus. Even though Ribbon menus has many advantages that simplifies accessing features, at times it’s a daunting task to navigate the Ribbon menus and find a specific command. Ribbon search is one of the interesting freeware tools to overcome these complaints from users, with this one can search Office ribbon for any feature or function easily. It supports both Office 2007 and  Office 2010(the versions which have ribbon). Once Installation has completed, you can find a text box on top of the ribbon in all the office applications (Outlook, Word, PowerPoint, Excel etc.). As you type few letters of the feature you are looking for, Ribbon Search instantly displays the path through which you can access the feature. Here is a screen grab search of Ribbon Search in action When you start typing itself shows results instantly. And also it gives the path through which you can access feature you are searching for. If there are multiple ways to access the feature, it is also shown in the list. Download Ribbon Search This article titled,Ribbon Search: Locate MS Office Ribbon Menu Features/Functions Quickly, was originally published at Tech Dreams.

• Find and hide file extension

  - by Daveo

  I am trying to find all files that have the same filename (excluding the file extension) that occur 3 times. I also need the full path to the file. What I have currently is #get file without extension alias lse="ls -1R | sed -e 's/\.[a-zA-Z]*$//'" #print out the current dir and get files occuring 3 times lse | sed "s;^;`pwd`/;" | sort | uniq -c | grep " 3 " This runs howver pwd prints the folder I ran the command from not the path to the file. So I tried find find . -type f | sed "s#^.#$(pwd)#" | sort | uniq -c This runs but includes the file extension. When I try to add sed -e 's/\.[a-zA-Z]*$//'" I get errors as I am not sure how to combine the two sed commands and I cannot seem to pipe a second time to sed? so what I am trying to do is find . -type f | sed "s#^.#$(pwd)#" | sed -e 's/\.[a-zA-Z]*$//'"| sort | uniq -c | grep " 3 " but this does not run.

• Using the option port on my Watchguard Firebox as a 2nd gateway exit point?

  - by Donovan

  I'm working on a network project in witch I have to design our network to provide two different exit points. The points are differentiated by the path through the corporate network. One of them travels through some monitoring hardware the other does not. We have a Watchguard Firebox in use as our gateway. Currently the network side provides the unmonitored exit point. I was wondering if i hooked the option port to our lan at a point that would force traffic through the monitored path, would it cause any problems? Access to the unmonitored gateway port would be restricted by ip. That would force all others not authorized to point to the monitored gateway port. I thought with the above design i might be able to get away with not having to buy another firebox to achieve the design I want. Thanks, D

• Coldfusion deployment under Apache Tomcat with Virtual Hosts

  - by smalltiger85

  Hello, I'm looking for the proper way to share the Coldfusion engine for all my Virtual Hosts. This is how I have the virtual hosts configured on server.xml in the Tomcat conf: <Host name="localhost" appBase="webapps" unpackWARs="false" autoDeploy="true" xmlValidation="false" xmlNamespaceAware="false"> <Context path="" docBase="cfusion/" reloadable="true" privileged="true" antiResourceLocking="false" anitJARLocking="false" allowLinking="true"/> </Host> <Host name="mysite1" appBase="webapps" xmlValidation="false" xmlNamespaceAware="false"> <Context path="" docBase="/mnt/webroot/mysite1" /> </Host> This is not valid for me because I'm instantiating one Coldfusion process for every virtual host, and it requires me to copy the WEB-INF folder in every site. My question is, is there any way to share the same Coldfusion instance for every virtual host, mantaining the sites webroot outside of the cfusion folder? I'm using Apache Tomcat 6 and Coldfusion Enterprise edition 8. Many thanks.

• Set-Cookie Headers getting stripped in ASP.NET HttpHandlers

  - by Rick Strahl

  Yikes, I ran into a real bummer of an edge case yesterday in one of my older low level handler implementations (for West Wind Web Connection in this case). Basically this handler is a connector for a backend Web framework that creates self contained HTTP output. An ASP.NET Handler captures the full output, and then shoves the result down the ASP.NET Response object pipeline writing out the content into the Response.OutputStream and seperately sending the HttpHeaders in the Response.Headers collection. The headers turned out to be the problem and specifically Http Cookies, which for some reason ended up getting stripped out in some scenarios. My handler works like this: Basically the HTTP response from the backend app would return a full set of HTTP headers plus the content. The ASP.NET handler would read the headers one at a time and then dump them out via Response.AppendHeader(). But I found that in some situations Set-Cookie headers sent along were simply stripped inside of the Http Handler. After a bunch of back and forth with some folks from Microsoft (thanks Damien and Levi!) I managed to pin this down to a very narrow edge scenario. It's easiest to demonstrate the problem with a simple example HttpHandler implementation. The following simulates the very much simplified output generation process that fails in my handler. Specifically I have a couple of headers including a Set-Cookie header and some output that gets written into the Response object.using System.Web; namespace wwThreads { public class Handler : IHttpHandler { /* NOTE: * * Run as a web.config set handler (see entry below) * * Best way is to look at the HTTP Headers in Fiddler * or Chrome/FireBug/IE tools and look for the * WWHTREADSID cookie in the outgoing Response headers * ( If the cookie is not there you see the problem! ) */ public void ProcessRequest(HttpContext context) { HttpRequest request = context.Request; HttpResponse response = context.Response; // If ClearHeaders is used Set-Cookie header gets removed! // if commented header is sent... response.ClearHeaders(); response.ClearContent(); // Demonstrate that other headers make it response.AppendHeader("RequestId", "asdasdasd"); // This cookie gets removed when ClearHeaders above is called // When ClearHEaders is omitted above the cookie renders response.AppendHeader("Set-Cookie", "WWTHREADSID=ThisIsThEValue; path=/"); // *** This always works, even when explicit // Set-Cookie above fails and ClearHeaders is called //response.Cookies.Add(new HttpCookie("WWTHREADSID", "ThisIsTheValue")); response.Write(@"Output was created.<hr/> Check output with Fiddler or HTTP Proxy to see whether cookie was sent."); } public bool IsReusable { get { return false; } } } } In order to see the problem behavior this code has to be inside of an HttpHandler, and specifically in a handler defined in web.config with: <add name=".ck_handler" path="handler.ck" verb="*" type="wwThreads.Handler" preCondition="integratedMode" /> Note: Oddly enough this problem manifests only when configured through web.config, not in an ASHX handler, nor if you paste that same code into an ASPX page or MVC controller. What's the problem exactly? The code above simulates the more complex code in my live handler that picks up the HTTP response from the backend application and then peels out the headers and sends them one at a time via Response.AppendHeader. One of the headers in my app can be one or more Set-Cookie. I found that the Set-Cookie headers were not making it into the Response headers output. Here's the Chrome Http Inspector trace: Notice, no Set-Cookie header in the Response headers! Now, running the very same request after removing the call to Response.ClearHeaders() command, the cookie header shows up just fine: As you might expect it took a while to track this down. At first I thought my backend was not sending the headers but after closer checks I found that indeed the headers were set in the backend HTTP response, and they were indeed getting set via Response.AppendHeader() in the handler code. Yet, no cookie in the output. In the simulated example the problem is this line:response.AppendHeader("Set-Cookie", "WWTHREADSID=ThisIsThEValue; path=/"); which in my live code is more dynamic ( ie. AppendHeader(token[0],token[1[]) )as it parses through the headers. Bizzaro Land: Response.ClearHeaders() causes Cookie to get stripped Now, here is where it really gets bizarre: The problem occurs only if: Response.ClearHeaders() was called before headers are added It only occurs in Http Handlers declared in web.config Clearly this is an edge of an edge case but of course - knowing my relationship with Mr. Murphy - I ended up running smack into this problem. So in the code above if you remove the call to ClearHeaders(), the cookie gets set!  Add it back in and the cookie is not there. If I run the above code in an ASHX handler it works. If I paste the same code (with a Response.End()) into an ASPX page, or MVC controller it all works. Only in the HttpHandler configured through Web.config does it fail! Cue the Twilight Zone Music. Workarounds As is often the case the fix for this once you know the problem is not too difficult. The difficulty lies in tracking inconsistencies like this down. Luckily there are a few simple workarounds for the Cookie issue. Don't use AppendHeader for Cookies The easiest and obvious solution to this problem is simply not use Response.AppendHeader() to set Cookies. Duh! Under normal circumstances in application level code there's rarely a reason to write out a cookie like this:response.AppendHeader("Set-Cookie", "WWTHREADSID=ThisIsThEValue; path=/"); but rather create the cookie using the Response.Cookies collection:response.Cookies.Add(new HttpCookie("WWTHREADSID", "ThisIsTheValue")); Unfortunately, in my case where I dynamically read headers from the original output and then dynamically  write header key value pairs back  programmatically into the Response.Headers collection, I actually don't look at each header specifically so in my case the cookie is just another header. My first thought was to simply trap for the Set-Cookie header and then parse out the cookie and create a Cookie object instead. But given that cookies can have a lot of different options this is not exactly trivial, plus I don't really want to fuck around with cookie values which can be notoriously brittle. Don't use Response.ClearHeaders() The real mystery in all this is why calling Response.ClearHeaders() prevents a cookie value later written with Response.AppendHeader() to fail. I fired up Reflector and took a quick look at System.Web and HttpResponse.ClearHeaders. There's all sorts of resetting going on but nothing that seems to indicate that headers should be removed later on in the request. The code in ClearHeaders() does access the HttpWorkerRequest, which is the low level interface directly into IIS, and so I suspect it's actually IIS that's stripping the headers and not ASP.NET, but it's hard to know. Somebody from Microsoft and the IIS team would have to comment on that. In my application it's probably safe to simply skip ClearHeaders() in my handler. The ClearHeaders/ClearContent was mainly for safety but after reviewing my code there really should never be a reason that headers would be set prior to this method firing. However, if for whatever reason headers do need to be cleared, it's easy enough to manually clear the headers out:private void RemoveHeaders(HttpResponse response) { List<string> headers = new List<string>(); foreach (string header in response.Headers) { headers.Add(header); } foreach (string header in headers) { response.Headers.Remove(header); } response.Cookies.Clear(); } Now I can replace the call the Response.ClearHeaders() and I don't get the funky side-effects from Response.ClearHeaders(). Summary I realize this is a total edge case as this occurs only in HttpHandlers that are manually configured. It looks like you'll never run into this in any of the higher level ASP.NET frameworks or even in ASHX handlers - only web.config defined handlers - which is really, really odd. After all those frameworks use the same underlying ASP.NET architecture. Hopefully somebody from Microsoft has an idea what crazy dependency was triggered here to make this fail. IAC, there are workarounds to this should you run into it, although I bet when you do run into it, it'll likely take a bit of time to find the problem or even this post in a search because it's not easily to correlate the problem to the solution. It's quite possible that more than cookies are affected by this behavior. Searching for a solution I read a few other accounts where headers like Referer were mysteriously disappearing, and it's possible that something similar is happening in those cases. Again, extreme edge case, but I'm writing this up here as documentation for myself and possibly some others that might have run into this. © Rick Strahl, West Wind Technologies, 2005-2012Posted in ASP.NET   IIS7   Tweet !function(d,s,id){var js,fjs=d.getElementsByTagName(s)[0];if(!d.getElementById(id)){js=d.createElement(s);js.id=id;js.src="//platform.twitter.com/widgets.js";fjs.parentNode.insertBefore(js,fjs);}}(document,"script","twitter-wjs"); (function() { var po = document.createElement('script'); po.type = 'text/javascript'; po.async = true; po.src = 'https://apis.google.com/js/plusone.js'; var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(po, s); })();

• Failover tmpfs mirroring. Am I doing it right?

  - by user45286

  My goal is to have a certain directory to be available as tmpfs. There will be some modifications during server uptime in this dir and those modifications must be synced to non-tmpfs persistent dir on HDD over rsync. After server boot the latest version from non-tmpfs persistent dir must be moved to tmpfs and rsync syncing to be started. I'm afraid that rsync will erase non-tmpfs backup if tmpfs dir will be empty.. I'm doing it in this way right now: create tmpfs partition in /etc/fstab cat /etc/rc.local (pseudocode) delete "tmpfs rsync" cronjob from /var/spool/cron/crontabs if there is any cp -r /path/to/non-tmpfs-backup /path/to/tmpfs/dir append /var/spool/cron/crontabs with "tmpfs rsync" cronjob What do you think?

• Installing Glassfish 3.1 on Ubuntu 10.10 Server

  - by andand

  I've used the directions here to successfully install Glassfish 3.0.1 on an virtualized (VirtualBox and VMWare) Ubuntu 10.10 Server instance without any real difficulty not resolved by more closely following the directions. However when I try applying them to Glassfish 3.1, I seem to keep getting stuck at section 6. "Security configuration before first startup". In particular, there are some differences I noted: 1) There are two keys in the default keystore. The 's1as' key is still there, but another named 'glassfish-instance' is also there. When I saw this, I deleted and recreated them both along with a 'myAlias' key which I was going to use where needed. 2) When turning the security on it seems like part of the server thinks it's on, but others don't. For instances: $ /home/glassfish/bin/asadmin set server-config.network-config.protocols.protocol.admin-listener.security-enabled=true server-config.network-config.protocols.protocol.admin-listener.security-enabled=true Command set executed successfully. $ /home/glassfish/bin/asadmin get server-config.network-config.protocols.protocol.admin-listener.security-enabled server-config.network-config.protocols.protocol.admin-listener.security-enabled=true Command get executed successfully. $ /home/glassfish/bin/asadmin --secure list-jvm-options It appears that server [localhost:4848] does not accept secure connections.

• Building Simple Workflows in Oozie

  - by dan.mcclary

  Introduction More often than not, data doesn't come packaged exactly as we'd like it for analysis. Transformation, match-merge operations, and a host of data munging tasks are usually needed before we can extract insights from our Big Data sources. Few people find data munging exciting, but it has to be done. Once we've suffered that boredom, we should take steps to automate the process. We want codify our work into repeatable units and create workflows which we can leverage over and over again without having to write new code. In this article, we'll look at how to use Oozie to create a workflow for the parallel machine learning task I described on Cloudera's site. Hive Actions: Prepping for Pig In my parallel machine learning article, I use data from the National Climatic Data Center to build weather models on a state-by-state basis. NCDC makes the data freely available as gzipped files of day-over-day observations stretching from the 1930s to today. In reading that post, one might get the impression that the data came in a handy, ready-to-model files with convenient delimiters. The truth of it is that I need to perform some parsing and projection on the dataset before it can be modeled. If I get more observations, I'll want to retrain and test those models, which will require more parsing and projection. This is a good opportunity to start building up a workflow with Oozie. I store the data from the NCDC in HDFS and create an external Hive table partitioned by year. This gives me flexibility of Hive's query language when I want it, but let's me put the dataset in a directory of my choosing in case I want to treat the same data with Pig or MapReduce code. CREATE EXTERNAL TABLE IF NOT EXISTS historic_weather(column 1, column2) PARTITIONED BY (yr string) STORED AS ... LOCATION '/user/oracle/weather/historic'; As new weather data comes in from NCDC, I'll need to add partitions to my table. That's an action I should put in the workflow. Similarly, the weather data requires parsing in order to be useful as a set of columns. Because of their long history, the weather data is broken up into fields of specific byte lengths: x bytes for the station ID, y bytes for the dew point, and so on. The delimiting is consistent from year to year, so writing SerDe or a parser for transformation is simple. Once that's done, I want to select columns on which to train, classify certain features, and place the training data in an HDFS directory for my Pig script to access.

USING '/path/to/hive/filters/ncdc_parser.py' as stn, wban, weather_year, weather_month, weather_day, temp, dewp, weather ) w; Since I'm going to prepare training directories with at least the same frequency that I add partitions, I should also add that to my workflow. Oozie is going to invoke these Hive actions using what's somewhat obviously referred to as a Hive action. Hive actions amount to Oozie running a script file containing our query language statements, so we can place them in a file called weather_train.hql. Starting Our Workflow Oozie offers two types of jobs: workflows and coordinator jobs. Workflows are straightforward: they define a set of actions to perform as a sequence or directed acyclic graph. Coordinator jobs can take all the same actions of Workflow jobs, but they can be automatically started either periodically or when new data arrives in a specified location. To keep things simple we'll make a workflow job; coordinator jobs simply require another XML file for scheduling. The bare minimum for workflow XML defines a name, a starting point, and an end point: <workflow-app name="WeatherMan" xmlns="uri:oozie:workflow:0.1"> <start to="ParseNCDCData"/> <end name="end"/> </workflow-app> To this we need to add an action, and within that we'll specify the hive parameters Also, keep in mind that actions require <ok> and <error> tags to direct the next action on success or failure. <action name="ParseNCDCData"> <hive xmlns="uri:oozie:hive-action:0.2"> <job-tracker>localhost:8021</job-tracker> <name-node>localhost:8020</name-node> <configuration> <property> <name>oozie.hive.defaults</name> <value>/user/oracle/weather_ooze/hive-default.xml</value> </property> </configuration> <script>ncdc_parse.hql</script> </hive> <ok to="WeatherMan"/> <error to="end"/> </action> There are a couple of things to note here: I have to give the FQDN (or IP) and port of my JobTracker and NameNode. I have to include a hive-default.xml file. I have to include a script file. The hive-default.xml and script file must be stored in HDFS That last point is particularly important. Oozie doesn't make assumptions about where a given workflow is being run. You might submit workflows against different clusters, or have different hive-defaults.xml on different clusters (e.g. MySQL or Postgres-backed metastores). A quick way to ensure that all the assets end up in the right place in HDFS is just to make a working directory locally, build your workflow.xml in it, and copy the assets you'll need to it as you add actions to workflow.xml. At this point, our local directory should contain: workflow.xml hive-defaults.xml (make sure this file contains your metastore connection data) ncdc_parse.hql Adding Pig to the Ooze Adding our Pig script as an action is slightly simpler from an XML standpoint. All we do is add an action to workflow.xml as follows: <action name="WeatherMan"> <pig> <job-tracker>localhost:8021</job-tracker> <name-node>localhost:8020</name-node> <script>weather_train.pig</script> </pig> <ok to="end"/> <error to="end"/> </action> Once we've done this, we'll copy weather_train.pig to our working directory. However, there's a bit of a "gotcha" here. My pig script registers the Weka Jar and a chunk of jython. If those aren't also in HDFS, our action will fail from the outset -- but where do we put them? The Jython script goes into the working directory at the same level as the pig script, because pig attempts to load Jython files in the directory from which the script executes. However, that's not where our Weka jar goes. While Oozie doesn't assume much, it does make an assumption about the Pig classpath. Anything under working_directory/lib gets automatically added to the Pig classpath and no longer requires a REGISTER statement in the script. Anything that uses a REGISTER statement cannot be in the working_directory/lib directory. Instead, it needs to be in a different HDFS directory and attached to the pig action with an <archive> tag. Yes, that's as confusing as you think it is. You can get the exact rules for adding Jars to the distributed cache from Oozie's Pig Cookbook. Making the Workflow Work We've got a workflow defined and have collected all the components we'll need to run. But we can't run anything yet, because we still have to define some properties about the job and submit it to Oozie. We need to start with the job properties, as this is essentially the "request" we'll submit to the Oozie server. In the same working directory, we'll make a file called job.properties as follows: nameNode=hdfs://localhost:8020 jobTracker=localhost:8021 queueName=default weatherRoot=weather_ooze mapreduce.jobtracker.kerberos.principal=foo dfs.namenode.kerberos.principal=foo oozie.libpath=${nameNode}/user/oozie/share/lib oozie.wf.application.path=${nameNode}/user/${user.name}/${weatherRoot} outputDir=weather-ooze While some of the pieces of the properties file are familiar (e.g., JobTracker address), others take a bit of explaining. The first is weatherRoot: this is essentially an environment variable for the script (as are jobTracker and queueName). We're simply using them to simplify the directives for the Oozie job. The oozie.libpath pieces is extremely important. This is a directory in HDFS which holds Oozie's shared libraries: a collection of Jars necessary for invoking Hive, Pig, and other actions. It's a good idea to make sure this has been installed and copied up to HDFS. The last two lines are straightforward: run the application defined by workflow.xml at the application path listed and write the output to the output directory. We're finally ready to submit our job! After all that work we only need to do a few more things: Validate our workflow.xml Copy our working directory to HDFS Submit our job to the Oozie server Run our workflow Let's do them in order. First validate the workflow: oozie validate workflow.xml Next, copy the working directory up to HDFS: hadoop fs -put working_dir /user/oracle/working_dir Now we submit the job to the Oozie server. We need to ensure that we've got the correct URL for the Oozie server, and we need to specify our job.properties file as an argument. oozie job -oozie http://url.to.oozie.server:port_number/ -config /path/to/working_dir/job.properties -submit We've submitted the job, but we don't see any activity on the JobTracker? All I got was this funny bit of output: 14-20120525161321-oozie-oracle This is because submitting a job to Oozie creates an entry for the job and places it in PREP status. What we got back, in essence, is a ticket for our workflow to ride the Oozie train. We're responsible for redeeming our ticket and running the job. oozie -oozie http://url.to.oozie.server:port_number/ -start 14-20120525161321-oozie-oracle Of course, if we really want to run the job from the outset, we can change the "-submit" argument above to "-run." This will prep and run the workflow immediately. Takeaway So, there you have it: the somewhat laborious process of building an Oozie workflow. It's a bit tedious the first time out, but it does present a pair of real benefits to those of us who spend a great deal of time data munging. First, when new data arrives that requires the same processing, we already have the workflow defined and ready to run. Second, as we build up a set of useful action definitions over time, creating new workflows becomes quicker and quicker.

• Ambiguous in the namespace problem

  - by Agha Usman Ahmed

  From the last few days, I was ignoring an error that keep coming at the compile time. I spent some two hours on it before but didn’t get it work. The error is quit confusing and of course difficult to manage. 'ApplicationSettingsBase' is ambiguous in the namespace 'System.Configuration' 'MailMessage' is ambiguous in the namespace 'System.Net.Mail' And there are couple of other similar errors that is pointing to some ambiguous references in my project.  The confusing part is that the MailMessage object throws similar error when you are importing the old and new email namespace. For example, Imports System.Web.Mail Imports System.Net.Mail So if you are only encountering ambiguous problem in MailMessage object. It is more possible that you have define both the namespaces in your code behind which is actually confusing the compiler about your referencing object. The quick solve for this problem is that remove Imports System.Web.Mail and it should work smooth. But with me, I never used the old asp.net mail namespace in my project. Then I start looking at my references and luckily I found the problem there. Follow the steps below to investigate the issue 1. Go to your project 2. Then references 3. Right click on “System” and see properties. it should point to the following path x:\Windows\Microsoft.NET\Framework\v2.0.50727\System.dll Where x is name of your operating system directory. This was the problem with my project. I had my operating system install on “D” drive and some how it is pointing to “C” drive which is the root cause of this problem. After that I verify all my references and found 5 –6 assemblies that are pointing to wrong path and get it worked. Also note, the problem can occur in any type of project either it is website , web application etc.

• How can a single script attached to multiple enemies provide separate behavior for each enemy?

  - by Syed

  I am making a TD game and now stucked at multiple enemies using same script. All is well with scripts attached with one enemy only. Problem is in running multiple enemies. Here is the overview. I have a Enemy object with which I have attached a 'RunEnemy' script. Flow of this script is: RunEnemy.cs: PathF p; p = gameObject.GetComponent<PathF>(); //PathF is a pathfinding algo which has 'search; function which returns a array of path from starting position PathList = p.search(starting position); //------------------------------- if(PathList != null) { //if a way found! if(moving forward) transform.Translate(someXvalue,0,0); //translates on every frame until next grid point else if(moving back) transform.Translate(0,someXvalue,0); ...and so on.. if(reached on next point) PathList = p.search(from this point) //call again from next grid point so that if user placed a tower enemy will run again on the returned path } Now I have attached this script and "PathF.cs" to a single enemy which works perfect. I have then made one more enemy object and attached both of these script to it as well, which is not working they both are overlapping movements. I can't understand why, I have attached these scripts on two different gameobjects but still their values change when either enemy changes its value. I don't want to go with a separate script for each enemy because there would be 30 enemies in a scene. How can I fix this problem?

• UnicodeEncodeError when uploading files in Django admin

  - by Samuel Linde

  Note: I asked this question on StackOverflow, but I realize this might be a more proper place to ask this kind of question. I'm trying to upload a file called 'Testaråäö.txt' via the Django admin app. I'm running Django 1.3.1 with Gunicorn 0.13.4 and Nginx 0.7.6.7 on a Debian 6 server. Database is PostgreSQL 8.4.9. Other Unicode data is saved to the database with no problem, so I guess the problem must be with the filesystem somehow. I've set http { charset utf-8; } in my nginx.conf. LC_ALL and LANG is set to 'sv_SE.UTF-8'. Running 'locale' verifies this. I even tried setting LC_ALL and LANG in my nginx init script just to make sure locale is set properly. Here's the traceback: Traceback (most recent call last): File "/srv/.virtualenvs/letebo/lib/python2.6/site-packages/django/core/handlers/base.py", line 111, in get_response response = callback(request, *callback_args, **callback_kwargs) File "/srv/.virtualenvs/letebo/lib/python2.6/site-packages/django/contrib/admin/options.py", line 307, in wrapper return self.admin_site.admin_view(view)(*args, **kwargs) File "/srv/.virtualenvs/letebo/lib/python2.6/site-packages/django/utils/decorators.py", line 93, in _wrapped_view response = view_func(request, *args, **kwargs) File "/srv/.virtualenvs/letebo/lib/python2.6/site-packages/django/views/decorators/cache.py", line 79, in _wrapped_view_func response = view_func(request, *args, **kwargs) File "/srv/.virtualenvs/letebo/lib/python2.6/site-packages/django/contrib/admin/sites.py", line 197, in inner return view(request, *args, **kwargs) File "/srv/django/letebo/app/cms/admin.py", line 81, in change_view return super(PageAdmin, self).change_view(request, obj_id) File "/srv/.virtualenvs/letebo/lib/python2.6/site-packages/django/utils/decorators.py", line 28, in _wrapper return bound_func(*args, **kwargs) File "/srv/.virtualenvs/letebo/lib/python2.6/site-packages/django/utils/decorators.py", line 93, in _wrapped_view response = view_func(request, *args, **kwargs) File "/srv/.virtualenvs/letebo/lib/python2.6/site-packages/django/utils/decorators.py", line 24, in bound_func return func(self, *args2, **kwargs2) File "/srv/.virtualenvs/letebo/lib/python2.6/site-packages/django/db/transaction.py", line 217, in inner res = func(*args, **kwargs) File "/srv/.virtualenvs/letebo/lib/python2.6/site-packages/django/contrib/admin/options.py", line 985, in change_view self.save_formset(request, form, formset, change=True) File "/srv/.virtualenvs/letebo/lib/python2.6/site-packages/django/contrib/admin/options.py", line 677, in save_formset formset.save() File "/srv/.virtualenvs/letebo/lib/python2.6/site-packages/django/forms/models.py", line 482, in save return self.save_existing_objects(commit) + self.save_new_objects(commit) File "/srv/.virtualenvs/letebo/lib/python2.6/site-packages/django/forms/models.py", line 613, in save_new_objects self.new_objects.append(self.save_new(form, commit=commit)) File "/srv/.virtualenvs/letebo/lib/python2.6/site-packages/django/forms/models.py", line 717, in save_new obj.save() File "/srv/.virtualenvs/letebo/lib/python2.6/site-packages/django/db/models/base.py", line 460, in save self.save_base(using=using, force_insert=force_insert, force_update=force_update) File "/srv/.virtualenvs/letebo/lib/python2.6/site-packages/django/db/models/base.py", line 504, in save_base self.save_base(cls=parent, origin=org, using=using) File "/srv/.virtualenvs/letebo/lib/python2.6/site-packages/django/db/models/base.py", line 543, in save_base for f in meta.local_fields if not isinstance(f, AutoField)] File "/srv/.virtualenvs/letebo/lib/python2.6/site-packages/django/db/models/fields/files.py", line 255, in pre_save file.save(file.name, file, save=False) File "/srv/.virtualenvs/letebo/lib/python2.6/site-packages/django/db/models/fields/files.py", line 92, in save self.name = self.storage.save(name, content) File "/srv/.virtualenvs/letebo/lib/python2.6/site-packages/django/core/files/storage.py", line 48, in save name = self.get_available_name(name) File "/srv/.virtualenvs/letebo/lib/python2.6/site-packages/django/core/files/storage.py", line 74, in get_available_name while self.exists(name): File "/srv/.virtualenvs/letebo/lib/python2.6/site-packages/django/core/files/storage.py", line 218, in exists return os.path.exists(self.path(name)) File "/srv/.virtualenvs/letebo/lib/python2.6/genericpath.py", line 18, in exists st = os.stat(path) UnicodeEncodeError: 'ascii' codec can't encode characters in position 52-54: ordinal not in range(128) I tried running Gunicorn with debugging turned on, and the file uploads without any problem at all. I suppose this must mean that the issue is with Nginx. Still beats me where to look, though.

This seem correct to me, so I'm still not sure why I keep getting these errors.

• Puppet won't execute command

  - by tom

  Puppet 0.25.4 on ubuntu point blank refuses to execute the following command: exec {"initiate replica set": command => "echo 'rs.initiate()' | mongo", path => ["/usr/bin","/usr/sbin","/bin"], user => "root", require => Class["mongodb"] } I can execute the command as root myself, so I'm guessing perhaps it's an issue with the shell. Unfortunately upgrading puppet isn't an option (and causes other issues anyway). I've tried specifying explicit paths to the binaries instead of relying on the path parameter, and also changing the command to: "bash -c \"echo 'rs.initiate()' | mongo\"" Still doesn't work. Any ideas? I get an error message saying something like "failed to change from notrun to 0"

• Install APC RedHat

  - by zackaryka

  i am trying to install apc on redhat so i did: pecl install apc i said yes to: Use apxs to set compile flags (if using APC with Apache)? [yes]: and i get this: checking for re2c... no configure: WARNING: You will need re2c 0.9.11 or later if you want to \ regenerate PHP parsers. and checking whether apc needs to get compiler flags from apxs... Sorry, I was not able to successfully run APXS. Possible reasons: 1. Perl is not installed; 2. Apache was not compiled with DSO support (--enable-module=so); 3. 'apxs' is not in your path. Try to use --with-apxs=/path/to/apxs The output of apxs follows /tmp/tmpJQuZdD/APC-3.0.16/configure: line 3846: apxs: command not found configure: error: Aborting ERROR: `/tmp/tmpJQuZdD/APC-3.0.16/configure --with-apxs' failed what could be the problem? Thanks
