Strange Symbol
When I was trying to commit my pom.xml, I click a few times commit and then i thought it hang as it doesn't show any changes, so I close eclipse but the following, all my project name and files not shown on the left pane

Getting error when building Node.js, but it seems builder does not load source from `BitBucket.
Pressing rebuild, but in first line it refers some old commit, why?
Don't press Rebuild on a specific build number as that will use the same commit as last time that build was run. Click on Builds->nodejs6 and click on the Start Build button for the top build configuration.
I want to share a step-by-step illustration on how to publish online your work on RStudio using GitHub pages.
A lot of people taking the Coursera courses on data have problems with it if they don't come from computer science, including myself, so I want to share a system that works. I'm sure it can be greatly improved.
Let's do it step-by-step, really easy:
1. Start with Github, not with RStudio.
Don't have an account, sign-up for one - it's free and incredibly valuable. Now go to Repositories (top menu bar), and press on the green button New in the upper-right-hand corner. Give a name to the repository ("test" for our puposes). You can skip the Description if you are in a hurry to proving to yourself that it works (same for the prompt to write some memo style one-liner under README). So go... click on Create Repository (green button). Now don't panic... just go directly to Settings (the cogwheel symbol in the vertical menu on the right-hand side). Perfect! One more click and we're there... Launch automatic page generator. Now we enter the guided part. Feel free to leave all this as is for now... We can modify it later, or we can go back and do it all over again when we know the end of the story (with a real repository that we do intend to publish. Click on Continue to layouts. Click on any of the designs (I chose "Architect)... And Publish page (green button upper-right corner). Beautiful!
Quick check: Click on Settings again, and check under GitHub Pages for the message: "Your site is published at http://...github.io/test. In my case the address is http://rinterested.github.io/test/ (was... I erased it after I finished this post) beacuse my Github account is RInterested. Very critical: pay attention to the structure: github.io without this there's no website. Now you can go to your browser, type the address and see that a new site has been born (caution: sometimes this takes minutes to materialize).
2. Now it's time to go to RStudio. If you're taking the Coursera course this is your comfort zone. If not I will assume that you've been working with [R], and that a simple download of RStudio (free online) is about to change your life for the better.
So we start RStudio and we go to the upper-right corner, where there is a cube containing an R, and the word Project. See it? Great, because we are going to start a New Project from the pull-down menu. Pop-up... which one to choose? Version Control is the answer. More pop-ups... No panicking... Click on the gray/red/green sideways GIT symbol ("Git Clone a project from a Git repository"). We have that, remember? We called it "Test". And we are facing a final screen with three fields to fill in. Under Repository URL we need to enter information that will require a quick trip back to Github for a second...
Are you there? OK... Do you see the HTTPS clone URL thing with a clipboard symbol on the right, half-way down within the test repository? Click on the clipboard symbol... Copied! Great! Now we go back to the screen with questions on RStudio, where we got re-routed, and do a right-click and paste, filling in the Repository URL field of the questionnaire. The rest is not critical. Press on Create Project... That's it!
3. Time to work. Let's now create a new R Markdown document by clicking on the corresponding option on the pull-down menu in the left-upper corner (green plus sign on a sheet of paper icon). Give it a name. You are the author. Select HTML. Click OK. Now you can modify, add, or just leave what popped-up on the screen as is to finish up the demonstration. Notice that there are so-called chunks of code started with ``{r} which indicate that the following code will be executed upon rendering the html document (or pdf). echo=FALSE means that only the result of the code (not the actual command) will be printed.
OK. Press on the top menu where you see a knitting pin (Knit HTML)... give it a name and save the document... Very important... whatever you name it it has to end up in .Rmd (case sensitive). What about "cars.Rmd"? Original enough... Save it and watch RStudio do its magic... Hopefully you're now admiring a beautiful webpage with a plot and numbers... Only one problem... It is NOT online.
4. Pushing our work to GitHub:
We are going now in the opposite direction. First, click on the GiT super-cool symbol on the top menu (above "knit HTML" depending on the configuration of your RStudio). It's a pull-down menu. Select Commit. You can select cars.html, or everything. Disregard a warning message, and post an ultra-short note under "Commit message". Whatever you want to write (e.g. "update"?). Click on the Commit button - very important! Now you are ready to click on Push... You guessed it... It's the green button. You will be prompted to enter your Github account Username and Password. Do so.
5. Back to GitHub:
Refresh the page displaying our "test" repository. You should now see the additional documents, including cars.html
Quick check: Go to your browser and enter in the URL bar what for me would be rinterested.github.io/test/cars.html (remember that you can get your own website address by going under Settings as explained above), and then just tag on the name of the document we have worked on with RStudio.
6. Hyperlink the pages:
As a test click on "index.html" under the "test" repository and somewhere there, in the body embed the following:
Click here to go to cars.
You will have to click on the pencil icon to edit this file. When done click on Commit changes. Go back on the browser to see your site. Refresh until it's updated with the hyperlink you just embedded. Click on it... You are now watching your RStudio work fully functional online. Magic!
Now it's just a matter to change things around using some html code quickly accessible online, changing the wording on the index.html (home page), or perhaps building a nice site with internal cohesiveness from scratch.
Good luck!
An alternative (more manual) approach - anything covered on the initial answer skipped.
1. Create a Repository in GitHub
Let's call it Course_project without need to README - we're just going to need its URL.
2. Open Windows PowerShell (or Git Bash)
Opening Git Bash is as simple as to right click on the directory in Windows Explorer we want to select, and click on Git Bash here. I'll use PowerShell. You can get the directory you're in by typing pwd. From there we can type ls to list subfolders, all along changing directory to reach where we want to be - for instance cd R to get R as the working directory.
Clone project by typing https://github.com/RInterested/Course_project.git (I am RInterested, so change that part to your GitHub username; also remember that "Course_project" is the name of this project). Change the directory to Course_project by typing cd Course_project. We now create a branch without parent branches: git checkout --orphan gh-pages. Make sure that the cloned Course_project is empty by typing: git rm -rf . We'll soon work with real RStudio markdown, but just to test what we have done so far, we can type into the empty working directory a name of a webpage: echo "Test Page" > index.html. Time now to Add/Commit/Push: git add index.html followed by git git commit -a -m "first commit", and git push origin gh-pages. This page is now visible at: http://RInterested.github.io/Course_project/index.html.
3. Creating content with RStudio
We have a directory (Course_project) and a toy index.html in it... We need real content. So we go to RStudio. Create an R Markdown file and name it (I'm calling it mtcars). Check HTML as the output. Change the document (some info about it in the answer above). Finally, an important step: Save it as Index.Rmd(make sure that the R working directory is the same as in PowerShell). Click on knit HTML to create the html file rendering the R code embedded in R Markdown.
4. Pushing it upstream with PowerShell
Now we have material within the directory Course_project, but it is not online - it is still local (you can go to it with Windows Explorer and see the html file under "index"). Type git status to see the changes made, and again follow the routine Add/Commit/Push: git add ., followed by git commit -a -m "commit", and git push origin gh-pages.
After a while the page will be live in http://RInterested.github.io/Course_project/index.html
5. Adding a second page
We can now start a second R Markdown file on RStudio (I labeled it Second_page and saved it as Second_page.Rmd. After writing what we want we knit HTML, and we can see these two new files appear in the Course_project local folder. We simply have to Add/Commit/Push like before in PowerShell. The new page will be in http://rinterested.github.io/Course_project/Second_page.html. It is very easy now to type a hyperlink on the first (index.Rmd) to the second (Second_page.html), knit the index.Rmd, and push it up to the web.
I'm following these steps to build sdrsharp on stable Debian. So fr, everything went without a hitch, but I can't figure out this step:
cd into the new sdrsharp directory and then load monodevelop and open the sdrsharp.sln project. If the .sln doesn't open use a text editor to open the .sln file and at the end of the first line change the 12.00 to 11.00. Older versions of monodevelop don't understand the VS2012 header.
Set the Active Configuration from Debug|x86 to Release|x86.
The first one is just given for context, monodevelop has no problem opening the file. But how do I change the Actove Configuration?
Monodevelops internal help is broken, I have no experience with monodevelop or similiar tools as I'm no coder, hence asking here.
Edit to add
The same question was asked and answered here, there should be an option under the "project" tab. But in my case, working from the downloaded .sln, all options under project are grayed out. What to do?
Fixed! The Version had to be changed back to 11 (first bullet point above, relevant to my special case), then reopen file, then it's opened as a project, not as a text file and all the options work.
Take home lessen: That a progeam opens a file without complaining does noit mean there's no error.
I have a Problem with a Windows Store App.
I moved the folder and now I cant compile it, I get the error:
Fehler 2 File C:\[old path]\Strings\en-US\Resources.resw not found. C:\[new path]\MakePRI
I dont know how to fix it because the app is in the same relative path in the project as before.
any hints for a solution?
This item was probably added to the project with absolute path. You can fix that in one of two ways:
In SolutionExplorer remove Resources.resw from the project. Then click on Show All Files icon to make the file appear in its folder although it's not included in the project (I understand you did copy it over when moving the project). Now right click on the file and select Include In Project. After that you can again turn off Show All Files.
In Solution Explorer right click on the project and select Unload Project. Now right click on the project again and select Edit ProjectName.csproj. In the file find Resources.resw and replace the existing tag (and any subtags) with <PRIResource Include="Strings\en-US\Resources.resw" />. Save the changes and close the file. Right click on the project again and select Reload Project.
I got into this problem and I found an easy solution. Open the project and it will show the error. Now right click on the App name in Solution Explorer (on the right hand side) and select Build.This will set the path again and the project can be run now.
I am trying to run the Playn example projects. I followed every step in this guide to setup new Playn development environment and then this guide to run sample projects.
it seem to work fine but when I try to run the HTML5 version by right click and then going to Google-> GWT compile, nothing happens. I don't see the development mode view poping up to copy the address and paste it to web browser as the guide says. I just get the following in the console window:
Compiling module playn.showcase.Showcase
Compiling 1 permutation
Compiling permutation 0...
Compile of permutations succeeded
Linking into L:\playn-samples\showcase\html\war\showcase
Link succeeded
Compilation succeeded -- 35.187s
Beyond that nothing happens. If I right click and select run as-> web application, I get the pop out saying
Could not find any hosting pages in the project playn-showcase-html
Anybody know what am I doing wrong ?
What you got from the compilation was all good.
"Beyond that nothing happens." is okay.
When you right click on the "playn-showcase-html" project, select "Run As - (g) Web Application", you should get an output to the "Development Mode" tab as "http://127.0.0.1:8888/Showcase.html?gwt.codesvr=127.0.0.1:9997".
If not, check if you have got the following folder structures under the "playn-showcase-html" project:
playn-showcase-html
|...
|--war
|--Showcase.html
|--WEB-INF
|--web.xml
As far as I know, you can't simply compile (GWT) and run the HTML version. This is because, the HTML version requires a local web server (such as jetty/tomcat) to host the files in order for the project to be 'run'. However, a simpler way around this would be to try using ant via Eclipse.
Window > Show View > Ant
Once the window appears (probably on a sidebar), right-click and select:
Add Buildfiles...
When the list of projects appear, expand the project by clicking the small arrow to the left of the project name in the list. Then select the ant build file:
build.xml
That will add the ant build file to your list of active build files.
Expand similarly to look at the ant tasks provided by the build file.
Double click on the appropriate task; in your case:
run-html
OR
Run ant directly on the command-line to get the same results.
In the current version of PlayN a jetty server is being started automatically. Right click on the xx-html project "Run As"->"maven install". This starts the GWT compiler, and starts a jetty server (default port is 8080), then you can run the HTML5 version by typing "localhost:8080" in yout browser.
I've also wrote a more detailed description about this on my blog getting started with eclipse and PlayN , maybe this could be interesting.
