  • JUJU and ERROR environment has no access-key or secret-key

    - by Riccardo Magrini
    following the official guide: [1]https://juju.ubuntu.com/docs/config-maas.html and considered that I've generated the ssh key (added it to UI of MAAS) and the API key, my environments.yaml file presents in this way: environments: maas: type: maas maas-server: 'http://x.x.x.x/MAAS/' maas-oauth: 'NDPA86PsEzS7bFynSy:vqJLkyHUJbvYzbtY5Q:sXXXXXXXXXXXXXXXXXXXXXX admin-secret: 'nothing' default-series: precise authorized-keys-path: ~/.ssh/id_rsa.pub # or any file you want. when I try to run the command: juju bootstrap receive the following error: ERROR environment has no access-key or secret-key Someone can explain me where is the wrong? MAAS and JUJU are installed using their ppa stable on an Ubuntu 12.04.3 Server

  • Formatted Ubuntu partition & now grub says "error: no such partition" - can't enter windows

    - by qwBJ
    I had installed Ubuntu (current version: 11.xx) alongside Windows Vista. Now I formatted the Ubuntu partition & merged it with another partition (without thinking, obviously). Now, when I restart the computer, GRUB probably tries to find the old partition (which does no longer exist) and says: error: no such partition. grub rescue> Now I dont know what to do (I'm a total beginner). I tried to re-install Ubuntu on the newly formatted partition but this won't work, because after removing the install-usb (which I am said to do during installation) I find the above error-message again. I guess I need some way to reconfigure grub OR to reinstall grub/ubuntu (on the newly formatted partition) OR to reinstall the windows boot manager (without reinstall. Windows), but I have no idea how to do either of these things.

  • Unrecoverable error during WUBI installation

    - by john
    I tried to install 12.10 on my PC with Windows 7 installed, but I don't have a CD drive and my PC doesn't support USB booting, so I tried the Windows Installer (WUBI). I had the ISO image mounted with daemon tools, so the Windows installer took those files and used them (I guess, because it didn't download any files). Everything went right, but when it prompted me to reboot, I rebooted the PC and then it starts to install, but when the installation process starts, a message that says: The installation found a unrecoverable error. pops out and makes me reboot, then when I select Ubuntu in the operating system selection screen, it says that an error occurred.

  • Visual Studio 2010 isn't building before a run when there are code changes. It was doing working yes

    - by jamone
    I've been using using F5 (Start Debugging) for years to build the code (if its out of date), and then debug. This was working on VS 2010 also, however today it just start debugging without a build. Say I do a clean on the project, and then hit F5 instead of building it so it can run it throws an error message saying that the exe doesn't exist to run. How do I make it build first? What could have changed?

  • Fixing LINQ Error: Sequence contains no elements

    - by ChrisD
    I’ve read some posts regarding this error when using the First() or Single() command.   They suggest using FirstOrDefault() or SingleorDefault() instead. But I recently encountered it when using a Sum() command in conjunction with a Where():   Code Snippet var effectiveFloor = policies.Where(p => p.PricingStrategy == PricingStrategy.EstablishFloor).Max(p => p.Amount);   When the Where() function eliminated all the items in the policies collection, the Sum() command threw the “Sequence contains no elements” exception.   Inserting the DefaultIfEmpty() command between the Where() and Sum(), prevents this error: Code Snippet var effectiveFloor = policies.Where(p => p.PricingStrategy == PricingStrategy.EstablishFloor).DefaultIfEmpty().Max(p => p.Amount);   but now throws a Null Reference exception!   The Fix: Using a combination of DefaultIfEmpty() and a null check in the Sum() command solves this problem entirely: Code Snippet var effectiveFloor = policies.Where(p => p.PricingStrategy == PricingStrategy.EstablishFloor).DefaultIfEmpty().Max(p =>  p==null?0 :p.Amount);

  • Where are classpath, path and pathelement documented in Ant version 1.8.0?

    - by Robert Menteer
    I'm looking over the documentation that comes with Apache Ant version 1.8.0 and can't find where classpath, path and pathelement are documented. I've found a page that describes path like structures but it doesn't list the valid attributes or nested elements for these. Another thing I can't find in the documentation is a description of the relationships between filelist, fileset, patternset and path and how to convert them back and forth. For instance there has to be an easier way to compile only those classes in one package while removing all class dependencies on the package classes and update documentation. <!-- Get list of files in which we're interested. --> <fileset id = "java.source.set" dir = "${src}"> <include name = "**/Package/*.java" /> </fileset> <!-- Get a COMMA separated list of classes to compile. --> <pathconvert property = "java.source.list" refid = "java.source.set" pathsep = ","> <globmapper from = "${src}/*.@{src.extent}" to = "*.class" /> </pathconvert> <!-- Remove ALL dependencies on package classes. --> <depend srcdir = "${src}" destdir = "${build}" includes = "${java.source.list}" closure = "yes" /> <!-- Get a list of up to date classes. --> <fileset id = "class.uptodate.set" dir = "${build}"> <include name = "**/*.class" /> </fileset> <!-- Get list of source files for up to date classes. --> <pathconvert property = "java.uptodate.list" refid = "class.uptodate.set" pathsep = ","> <globmapper from="${build}/*.class" to="*.java" /> </pathconvert> <!-- Compile only those classes in package that are not up to date. --> <javac srcdir = "${src}" destdir = "${build}" classpathref = "compile.classpath" includes = "${java.source.list}" excludes = "${java.uptodate.list}"/> <!-- Get list of directories of class files for package. --: <pathconvert property = "class.dir.list" refid = "java.source.set" pathsep = ","> <globmapper from = "${src}/*.java" to = "${build}*" /> </pathconvert> <!-- Convert directory list to path. --> <path id = "class.dirs.path"> <dirset dir = "${build}" includes = "class.dir.list" /> </path> <!-- Update package documentation. --> <jdepend outputfile = "${docs}/jdepend-report.txt"> <classpath refid = "compile.classpath" /> <classpath location = "${build}" /> <classespath> <path refid = "class.dirs.path" /> </classespath> <exclude name = "java.*" /> <exclude name = "javax.*" /> </jdepend> Notice there's a number of conversions between filesets, paths and comma separated list just to get the proper 'type' required for the different ant tasks. Is there a way to simplify this while still processing the fewest files in a complex directory structure?

  • Xcode - duplicate Target - new Target fails to build

    - by SirRatty
    Hi all, using Xcode 3.2.5 on 10.6.6 (10J521) I have an Xcode project containing 1 Target: "MyApp". It builds and runs successfully. As well as source and resource files, the Target contains a "Copy Files" build phase which copies "Sparkle.framework" in. The framework is in the same directory as the project. I want to duplicate this Target. Steps taken: Did "Clean all Targets". Right-clicked on the "MyApp" Target within Xcode, and then chose "Duplicate". Renamed the duplicated target to "MyAppTarget2". Selected "MyAppTarget2" as the Active Target from the popup menu in the top-left. Did "Build". The problem: error: Sparkle/Sparkle.h: No such file or directory This is puzzling! Each Build step appears to have been replicated in the duplicated Target, including the "Copy Files" phase. The Sparkle.framework exists at the path indicated by [Get Info on the Copy Phase item]. If I right-click on the Sparkle.framework file within the "Copy Files" build phase of the duplicated Target, and select "Reveal in Finder", then the correct Sparkle.framework file is shown. The required file exists at Sparkle.framework/Headers/Sparkle.h If I switch back to the original "MyApp" target, it builds and runs successfully. Am I doing something obviously wrong here? Thanks.

  • How Visual Studio 2010 and Team Foundation Server enable Compliance

    - by Martin Hinshelwood
    One of the things that makes Team Foundation Server (TFS) the most powerful Application Lifecycle Management (ALM) platform is the traceability it provides to those that use it. This traceability is crucial to enable many companies to adhere to many of the Compliance regulations to which they are bound (e.g. CFR 21 Part 11 or Sarbanes–Oxley.)   From something as simple as relating Tasks to Check-in’s or being able to see the top 10 files in your codebase that are causing the most Bugs, to identifying which Bugs and Requirements are in which Release. All that information is available and more in TFS. Although all of this tradability is available within TFS you do need to understand that it is not for free. Well… I say that, but if you are using TFS properly you will have this information with no additional work except for firing up the reporting. Using Visual Studio ALM and Team Foundation Server you can relate every line of code changes all the way up to requirements and back down through Test Cases to the Test Results. Figure: The only thing missing is Build In order to build the relationship model below we need to examine how each of the relationships get there. Each member of your team from programmer to tester and Business Analyst to Business have their roll to play to knit this together. Figure: The relationships required to make this work can get a little confusing If Build is added to this to relate Work Items to Builds and with knowledge of which builds are in which environments you can easily identify what is contained within a Release. Figure: How are things progressing Along with the ability to produce the progress and trend reports the tractability that is built into TFS can be used to fulfil most audit requirements out of the box, and augmented to fulfil the rest. In order to understand the relationships, lets look at each of the important Artifacts and how they are associated with each other… Requirements – The root of all knowledge Requirements are the thing that the business cares about delivering. These could be derived as User Stories or Business Requirements Documents (BRD’s) but they should be what the Business asks for. Requirements can be related to many of the Artifacts in TFS, so lets look at the model: Figure: If the centre of the world was a requirement We can track which releases Requirements were scheduled in, but this can change over time as more details come to light. Figure: Who edited the Requirement and when There is also the ability to query Work Items based on the History of changed that were made to it. This is particularly important with Requirements. It might not be enough to say what Requirements were completed in a given but also to know which Requirements were ever assigned to a particular release. Figure: Some magic required, but result still achieved As an augmentation to this it is also possible to run a query that shows results from the past, just as if we had a time machine. You can take any Query in the system and add a “Asof” clause at the end to query historical data in the operational store for TFS. select <fields> from WorkItems [where <condition>] [order by <fields>] [asof <date>] Figure: Work Item Query Language (WIQL) format In order to achieve this you do need to save the query as a *.wiql file to your local computer and edit it in notepad, but one imported into TFS you run it any time you want. Figure: Saving Queries locally can be useful All of these Audit features are available throughout the Work Item Tracking (WIT) system within TFS. Tasks – Where the real work gets done Tasks are the work horse of the development team, but they only as useful as Excel if you do not relate them properly to other Artifacts. Figure: The Task Work Item Type has its own relationships Requirements should be broken down into Tasks that the development team work from to build what is required by the business. This may be done by a small dedicated group or by everyone that will be working on the software team but however it happens all of the Tasks create should be a Child of a Requirement Work Item Type. Figure: Tasks are related to the Requirement Tasks should be used to track the day-to-day activities of the team working to complete the software and as such they should be kept simple and short lest developers think they are more trouble than they are worth. Figure: Task Work Item Type has a narrower purpose Although the Task Work Item Type describes the work that will be done the actual development work involves making changes to files that are under Source Control. These changes are bundled together in a single atomic unit called a Changeset which is committed to TFS in a single operation. During this operation developers can associate Work Item with the Changeset. Figure: Tasks are associated with Changesets   Changesets – Who wrote this crap Changesets themselves are just an inventory of the changes that were made to a number of files to complete a Task. Figure: Changesets are linked by Tasks and Builds   Figure: Changesets tell us what happened to the files in Version Control Although comments can be changed after the fact, the inventory and Work Item associations are permanent which allows us to Audit all the way down to the individual change level. Figure: On Check-in you can resolve a Task which automatically associates it Because of this we can view the history on any file within the system and see how many changes have been made and what Changesets they belong to. Figure: Changes are tracked at the File level What would be even more powerful would be if we could view these changes super imposed over the top of the lines of code. Some people call this a blame tool because it is commonly used to find out which of the developers introduced a bug, but it can also be used as another method of Auditing changes to the system. Figure: Annotate shows the lines the Annotate functionality allows us to visualise the relationship between the individual lines of code and the Changesets. In addition to this you can create a Label and apply it to a version of your version control. The problem with Label’s is that they can be changed after they have been created with no tractability. This makes them practically useless for any sort of compliance audit. So what do you use? Branches – And why we need them Branches are a really powerful tool for development and release management, but they are most important for audits. Figure: One way to Audit releases The R1.0 branch can be created from the Label that the Build creates on the R1 line when a Release build was created. It can be created as soon as the Build has been signed of for release. However it is still possible that someone changed the Label between this time and its creation. Another better method can be to explicitly link the Build output to the Build. Builds – Lets tie some more of this together Builds are the glue that helps us enable the next level of tractability by tying everything together. Figure: The dashed pieces are not out of the box but can be enabled When the Build is called and starts it looks at what it has been asked to build and determines what code it is going to get and build. Figure: The folder identifies what changes are included in the build The Build sets a Label on the Source with the same name as the Build, but the Build itself also includes the latest Changeset ID that it will be building. At the end of the Build the Build Agent identifies the new Changesets it is building by looking at the Check-ins that have occurred since the last Build. Figure: What changes have been made since the last successful Build It will then use that information to identify the Work Items that are associated with all of the Changesets Changesets are associated with Build and change the “Integrated In” field of those Work Items . Figure: Find all of the Work Items to associate with The “Integrated In” field of all of the Work Items identified by the Build Agent as being integrated into the completed Build are updated to reflect the Build number that successfully integrated that change. Figure: Now we know which Work Items were completed in a build Now that we can link a single line of code changed all the way back through the Task that initiated the action to the Requirement that started the whole thing and back down to the Build that contains the finished Requirement. But how do we know wither that Requirement has been fully tested or even meets the original Requirements? Test Cases – How we know we are done The only way we can know wither a Requirement has been completed to the required specification is to Test that Requirement. In TFS there is a Work Item type called a Test Case Test Cases enable two scenarios. The first scenario is the ability to track and validate Acceptance Criteria in the form of a Test Case. If you agree with the Business a set of goals that must be met for a Requirement to be accepted by them it makes it both difficult for them to reject a Requirement when it passes all of the tests, but also provides a level of tractability and validation for audit that a feature has been built and tested to order. Figure: You can have many Acceptance Criteria for a single Requirement It is crucial for this to work that someone from the Business has to sign-off on the Test Case moving from the  “Design” to “Ready” states. The Second is the ability to associate an MS Test test with the Test Case thereby tracking the automated test. This is useful in the circumstance when you want to Track a test and the test results of a Unit Test designed to test the existence of and then re-existence of a a Bug. Figure: Associating a Test Case with an automated Test Although it is possible it may not make sense to track the execution of every Unit Test in your system, there are many Integration and Regression tests that may be automated that it would make sense to track in this way. Bug – Lets not have regressions In order to know wither a Bug in the application has been fixed and to make sure that it does not reoccur it needs to be tracked. Figure: Bugs are the centre of their own world If the fix to a Bug is big enough to require that it is broken down into Tasks then it is probably a Requirement. You can associate a check-in with a Bug and have it tracked against a Build. You would also have one or more Test Cases to prove the fix for the Bug. Figure: Bugs have many associations This allows you to track Bugs / Defects in your system effectively and report on them. Change Request – I am not a feature In the CMMI Process template Change Requests can also be easily tracked through the system. In some cases it can be very important to track Change Requests separately as an Auditor may want to know what was changed and who authorised it. Again and similar to Bugs, if the Change Request is big enough that it would require to be broken down into Tasks it is in reality a new feature and should be tracked as a Requirement. Figure: Make sure your Change Requests only Affect Requirements and not rewrite them Conclusion Visual Studio 2010 and Team Foundation Server together provide an exceptional Application Lifecycle Management platform that can help your team comply with even the harshest of Compliance requirements while still enabling them to be Agile. Most Audits are heavy on required documentation but most of that information is captured for you as long a you do it right. You don’t even need every team member to understand it all as each of the Artifacts are relevant to a different type of team member. Business Analysts manage Requirements and Change Requests Programmers manage Tasks and check-in against Change Requests and Bugs Testers manage Bugs and Test Cases Build Masters manage Builds Although there is some crossover there are still rolls or “hats” that are worn. Do you thing this is all achievable? Have I missed anything that you think should be there?

    When trying to install SQL Server 2008 Service Pack 1 to a SQL Server 2008 instance that is running on a virtual machine, the installer will start:   But then after about 20 seconds I receive the following error message: TITLE: SQL Server Setup failure. ----------------------------- SQL Server Setup has encountered the following error: Invoke or BeginInvoke cannot be called on a control until the window handle has been created. ------------------------------ BUTTONS: OK ------------------------------ Searching for this issue I found that several people have the same problem and there is no clear solution.  Some had success with closing windows or Internet Explorer but that didn’t work for me; what did work is to make sure the SQL Server 2008 “Please wait while SQL Server 2008 Setup processes the current operation.” dialog is selected and has the focus when it first shows up.  Selected (with the current focus) it looks like this:   Without focus the dialog looks like this: Add a comment if you find out any information about how to consistently get around this issue or why it is happening in the first place.

  • How to recursive rake? -- or suitable alternatives

    - by TerryP
    I want my projects top level Rakefile to build things using rakefiles deeper in the tree; i.e. the top level rakefile says how to build the project (big picture) and the lower level ones build a specific module (local picture). There is of course a shared set of configuration for the minute details of doing that whenever it can be shared between tasks: so it is mostly about keeping the descriptions of what needs building, as close to the sources being built. E.g. /Source/Module/code.foo and cie should be built using the instructions in /Source/Module/Rakefile; and /Rakefile understands the dependencies between modules. I don't care if it uses multiple rake processes (ala recursive make), or just creates separate build environments. Either way it should be self-containable enough to be processed by a queue: so that non-dependent modules could be built simultaneously. The problem is, how the heck do you actually do something like that with Rake!? I haven't been able to find anything meaningful on the Internet, nor in the documentation. I tried creating a new Rake::Application object and setting it up, but whatever methods I try invoking, only exceptions or "Don't know how to build task ':default'" errors get thrown. (Yes, all rakefiles have a :default). Obviously one could just execute 'rake' in a sub directory for a :modulename task, but that would ditch the options given to the top level; e.g. think of $(MAKE) and $(MAKEFLAGS). Anyone have a clue on how to properly do something like a recursive rake?

  • Strange javascript error when using Kongregates API

    - by Phil
    In the hopes of finding a fellow unity3d developer also aiming for the Kongregate contest.. I've implemented the Kongregate API and can see that the game receives a call with my username and presents it ingame. I'm using Application.ExternalCall("kongregate.stats.submit",type,amount); where type is a string "Best Score" and amount is an int (1000 or something). This is the error I'm getting: You are trying to call recursively into the Flash Player which is not allowed. In most cases the JavaScript setTimeout function, can be used as a workaround. callASFunction:function(a,b){if(FABrid...tion, can be used as a workaround."); I'm wondering, has anyone else had this error or am I somehow doing something stupid? Thanks!

  • Installing Enclosure with Netbeans

    - by jdknewb
    Hi all, I am having trouble installing Enclosure and getting it to work. I have followed this guide http://www.enclojure.org/gettingstarted and successfully installed Enclosure (I think). However, when I try to build the sample application (labrepl) I get a bunch of errors and a failed build. I haven't used Java in a long time and I've never used Netbeans, and the error doesn't seem very helpful with my limited knowledge of this domain. I'm using the latest Netbeans and the Enclosure URL from the guide. Since I am on Windows, I can't use git to clone the repo, so I'm not sure what to do from here. Anyway, here are the error messages. WARNING: You are running embedded Maven builds, some build may fail due to incompatibilities with latest Maven release.

  • Errors In Programmatically Running ANT Build In Eclipse

    - by Sujay
    I am trying to run an ANT script through a small Java program and I keep on encountering the following error: build: Exception in thread "main" build.xml:7: Problem: failed to create task or type eclipse.refreshLocal Cause: The name is undefined. Action: Check the spelling. Action: Check that any custom tasks/types have been declared. Action: Check that any <presetdef>/<macrodef> declarations have taken place. at org.apache.tools.ant.UnknownElement.getNotFoundException(UnknownElement.java:487) at org.apache.tools.ant.UnknownElement.makeObject(UnknownElement.java:419) at org.apache.tools.ant.UnknownElement.maybeConfigure(UnknownElement.java:163) I used to get this problem when I used to execute the build file manually. All I had to do to make Eclipse run this build was to go to Run External Tools External Tools Configuration JRE and select "Run in the same JRE as the workspace" and then attempt to execute. But I have no idea how to achieve the same effect through my code. Any suggestion would really be appreciated. Note that this has reference to a previous question that I asked over here

  • Android: debug certificate expired error

    - by Bill Osuch
    I started up Eclipse today, created a new project, and immediately had an error before I had changed a single line: Error generating final archive: Debug Certificate expired on 11/12/11 When installed, the Android SDK generates a "debug" signing certificate for you in a file called "debug.keystore". Eclipse uses this certificate rather than forcing you to create a new one for every project. In older versions of Eclipse, the certificate was only valid for 365 days, but as I understand it the default has been changed to 30 years in newer versions. If for whatever reason you don't want to upgrade Eclipse, you can manually delete the certificate to for Eclipse to generate a new one. You can find the location in Preferences -> Android -> Build -> Default debug keystore (mine was in C:\Users\myUserName\.android\); just delete the "debug.keystore" file, then go back into Eclipse and Clean the project to generate a new file.

The problem is one one hand i cannot proceed with the complete installation and on other hand if i remove the CD, am not able to boot windows as it says No bootable device.

  • Proving the ROI of a technology?

    - by leeand00
    How does one prove the ROI of a technology to their manager? The closest thing I have found to a document on how to do this is: http://www.agilejournal.com/pdf/Finding-ROI-in-Build-Automation.pdf There are formulas in this document, but I can't really tell if they are just alot of marketing or if they are accurate formulas on how to calculate ROI. I'm not really trying to calculate the ROI of the build tool in the above paper, I was just trying to calculate the ROI of a simple build tool like ANT.

  • What does intermittent "Input/output error" suggest?

    - by dan
    Lately my Ubuntu 12 system has started acting very strange. Sometimes the computer freezes and then unfreezes 2 minutes later, and other times when I try a basic command like less I get the error bash: /usr/bin/less: Input/output error. But this is intermittent too. Any suggestions? Also if I try sudo reboot and enter my password, I get sudo: unable to open /var/lib/sudo/plato/7: Read-only file system Before I used to be able to do sudo reboot fine. If I tail /var/log/syslog I do see these curious lines: .... ata1: softreset failed (device not ready) .... ata1: hard resettting link .... ata1: link is slow to respond, please be patient (ready=0) What can I do to fix this?

    - by Mirage
    Sorry for asking this question but i searched all java realted question but i got more confused. I am still not clear what should i start with 1)My main is build website in Java because someone told me that there are some machine learning or AI libraries available in java which i can use in java. so i decided to use that as it can reduce my work. Now i don't know java at all some people say following are used to build websites like 1)Servelts alone can build webiste 2)JSP alone can also build webiste 3)Struts 4)Spring with Hibernate 5)SEAM 6)JEE also for webistes Now guys i am confused where should i start from. Where does core JAVA fits in here. i was thinking of perhaps learning python as i know i have to learn Python only not its variations SO please guide me one thing which can solve my basic purpose of using ready made libraries of AI If i can do that with JSP then i will start with that. But i need to learn all of them then its better if can start learning python. I have 5 months to finish webiste. I really don't know why there are many braches of java for doing one thing Please help me.
