"Organizing School Workspace/Writing Makefile",

I want to be able to include these files in a project's workspace (2520/assignments/A2) without having to copy the files because I don't want to manage to copies of a file and I don't want to check in two copies of the same file in SVN.\nI would like to have the library files in the project workspace so my Makefile works without having to do to much manual configuration (or hard-coding paths).\n\nAt first, I thought about symbolic links (which SVN and tar support) but I can't seem to compile my assignment given my headers in another directory.\n\nI can manually compile each header to an object file and do the final linking, but I'm not sure how to do this in a Makefile automatically. \n\nAny help or any alternative to how I have my environment setup is appreciated.\n\nThanks!\n\nEDIT: I forgot to mention that I have searched Google and have found a few pages describing automatic dependency generation (perhaps I want this?) using gcc -MM and I have read over the GNU Make manual but nothing jumped out at me."

Normally this is irrelevant, but when something goes wrong seeing the state of Derived can be important, but pimpl obscures the state too much (however that's the original idea of a pimpl, so I guess I can't really complain).\n\nNow I have a tostring() function that prints the state out for debug purposes, but was wondering if there is a better solution, to debug this sort of construct in VisualStudio in particular, but a general solution would be better.\n\nThanks"

"Discontinuous axis in Matplotlib with categorical variable on axis",
"I have a plot of values w/ errorbars with a categorical variable on the X-axis, made using the errorbar method. I have followed the instructions here to create a discontinuity in the X-axis (I'm only showing points with values > or < some absolute threshold).\n\nSo far so good, with one slight issue - the axis break ends up being exactly on a data point on each side, which makes it harder to read on the axis, and also, the datapoints themselves end up split in two, which is kind of awkward.\nI would like the axis break to instead be between datapoints, something like:\n----(last value before break)--/ /--(first value after break)----\nIs there a way to do this?\nThe breakpoints are determined with set_xlim, and I'm not sure if there's a way to do move them off the datapoints with a categorical x-axis...\nsort_res_h = sort_res_a[sort_res_a > threshold]\nsort_res_l = sort_res_a[sort_res_a < -threshold]\n\nax0.errorbar(sort_res_a.index, sort_res_a, yerr=chg_dpm_err, fmt='o')\nax1.errorbar(sort_res_a.index, sort_res_a, yerr=chg_dpm_err, fmt='o')\n\nax0.set_xlim(xmax=sort_res_h.index[-1])\nax1.set_xlim(xmin=sort_res_l.index[0])"

"Move 2 windows forms together unless the second form is minimized",
"So 2 days ago I asked how to move 2 forms together, I got this answer which really helped me. But now I would like to know how to move the first form, while the second one is minimized (so it has to stop moving while minimized, or it will result in a crash from the second form...)?\nI tried this:\n\nprivate void MainForm_LocationChanged(object sender, EventArgs e) {\n // All open child forms to be moved\n Form[] formsToAdjust = Application\n .OpenForms\n .OfType<ChildForm>()\n .ToArray();\n FormsToAdjust formsToAdjust1 = new FormsToAdjust(); //added this\n\n // If the main form has been moved...\nif (formsToAdjust1.WindowState != FormWindowState.Minimized) //and this statement as well\n{\n if (m_PreviousLocation.X != int.MinValue)\n foreach (var form in formsToAdjust) //... we move all child froms aw well\n form.Location = new Point(\n form.Location.X + Location.X - m_PreviousLocation.X,\n form.Location.Y + Location.Y - m_PreviousLocation.Y\n );\n\n m_PreviousLocation = Location;\n}\n}\n\n\nbut it can't work as it will open the second form each time the main form will be moved (yes this was a stupid attempt, but I really can't manage how to go through that problem)...\nSo the goal would be to, if the second form is minimized, keep being able to move the main form, without changing the location of the second one.\nAny help would be really appreciated, I'm going to continue searching by my side (actually searching for a while now) while waiting for a reply.Thanks :)"

"On closing the main Swing window, the other thread on the EventQueue gets not created",
"I write Java SE 8 desktop application. It's got a Swing UI.\n\nPlatform:\n\n\nEclipse IDE\nWindows 10 OS\n\n\nNow when I close the main window, by pressing on the \"X\" on the top-right-corner, I have a listener to listen for such event.\n\nThe listener right here:\n\n private void listenerForClosingResources(){\n this.addWindowListener(new WindowAdapter() {\n @Override\n public void windowClosing(WindowEvent e) {\n if(e.getID() == WindowEvent.WINDOW_CLOSING){\n CountDownLatch continueOn = new CountDownLatch(1);\n saveUnsavedTmpProject(continueOn);\n\n try {\n continueOn.await();\n }\n catch(InterruptedException ee) {\n ee.printStackTrace();\n } \n }\n }\n }); \n }\n\n\nSo, I use the listener to identify the window closing event, and when that happens I ask the user whether or not to save the project (it's data on DB).\n\nThis method (saveUnsavedTmpProject(continueOn);) leads to the other window which supposed to take the name under which to save the project.\n\nNow the CountDownLatch forces the main window to stay up, up till when the user confirms/rejects saving the project on the other panel.\n\nThe other class method which creates the window, leading to saving the project, is right here:\n\npublic static void getInstance(CountDownLatch continueOn, String openProjectName) {\n if(frame == null) {\n synchronized(SaveAsPane.class) {\n if(frame == null) {\n carryOn = continueOn;\n\n if(!openProjectName.isEmpty()){\n openProject = openProjectName;\n }\n\n EventQueue.invokeLater(new Runnable() {\n public void run() {\n try {\n frame = new SaveAsPane();\n frame.setVisible(true);\n frame.setLocationRelativeTo(MainGUI.getMainGUI());\n\n } catch (Exception e) {\n e.printStackTrace();\n }\n }\n }); \n }\n }\n }\n }\n\n\nNow, when I run the app, I don't get inside the run() method (and no window pops-up). But that only happens when I access this method only from the mentioned above listener. Which has the CountDownLatch, and it appears that it stops the execution of the new thread.\n\nThe latch gets counted-down when the user confirms/denies saving the project, so that the execution flow continues on.\nYet, I create the additional thread on the EventQueue.\n\nHow come that the thread gets stopped?"

If you need the code for widescreen iphones I will leave it in my own answer below, it runs on all iPhones above iPhone 4 and all iPads."

"Rails Multiple Input Field in Form to One Integer Attribute in Model",
"I am trying to allow a user to input two different things in two different drop down menus from the same form and it will store an integer into a review table.\n\nI want the user to be able to select model_name in one drop down and manufacturer in another drop down.

(Telling you which bat the user is selecting)\n\nI have seen a couple questions about date & time but they store the values directly in the model.

However I still think there is a way to store one value in my review model. I am using javascript very similiar to this"

"doxygen relative image paths and source directory structure",
"I use doxygen for documentation, and I have my sources under git. \nI want paths in my documentation to be relative to the project dir, as I check it out in different places.\n\nAs the html subdir is generated by doxygen, it is not under version control. \n\nHowever, it seems if I want to use relative paths for images, I need to put the images somewhere under the html directory - I played with using \"../images\" as IMAGE_PATH, that does not work.\n\nMy images should be under version control.\n\nIs there a good way to organize my sources to make this work?"

"In R, plot a histogram of how many time-points have viable data for each participant",
"I have a large data frame for which I want to be able to plot a histogram of the number of viable sessions -- indicated by any value other than NA -- for all participants in order to determine whether they are completing a sufficient number of sessions to be included in analysis and whether there is a clear cut-off point for how many sessions most people have scores for. Each participant should complete 10 sessions for the study, but some have missing sessions, indicated by NA. \n\nThe real data frame is large and contains participant data I can't show, but I've recreated a smaller sample version here that has the essential columns which are the participant ID, the score they got during each session, and the session number.\n\n\n\nCode to recreate the data frame:\n\ndat <- cbind(c(rep(1:3,10)), c(rep(c(12, 32, NA, 44, 45, NA, NA, 8, 54, NA, NA, 12, 13, 14, NA),2)), c(rep(1,3), rep(2,3), rep(3,3), rep(4,3), rep(5,3), rep(6,3), rep(7,3), rep(8,3), rep(9,3), rep(10,3)))\ncolnames(dat) <- c(\"ID\", \"score\", \"session.num\")\n\n\nThank you in advance for your help.

"android studio 3.1: can custom adapter display null image id?",
"please excuse me for my poor english, my question might look silly, but i wondering how custom array adapter work in the android studio 3.1\n\nfirst i create a custom adapter to handle my array of object it looks like this:\n\npackage com.example.android.miwok;\n\nimport android.support.annotation.NonNull;\nimport android.support.annotation.Nullable;\nimport android.view.LayoutInflater;\nimport android.view.View;\nimport android.view.ViewGroup;\nimport android.widget.ArrayAdapter;\nimport android.widget.ImageView;\nimport android.widget.TextView;\nimport android.app.Activity;\n\nimport java.util.ArrayList;\n\npublic class WordAdapter extends ArrayAdapter<Word> {\n\n public WordAdapter(Activity context, ArrayList<Word> words){\n // Here, we initialize the ArrayAdapter's internal storage for the context and the list.\n // the second argument is used when the ArrayAdapter is populating a single TextView.\n // Because this is a custom adapter for two TextViews and an ImageView, the adapter is not\n // going to use this second argument, so it can be any value. Here, we used 0.\n super(context,0,words);\n }\n\n @NonNull\n @Override\n public View getView(int position, @Nullable View convertView, @NonNull ViewGroup parent) {\n View listItemView = convertView;\n // Check if the existing view is being reused, otherwise inflate the view\n if(listItemView == null) {\n listItemView = LayoutInflater.from(getContext()).inflate(\n R.layout.list_item, parent, false);\n }\n\n Word currentWord = getItem(position);\n\n TextView defaultWord = (TextView) listItemView.findViewById(R.id.default_text_view);\n defaultWord.setText(currentWord.getDefaultTranslation());\n\n TextView miwokWord = (TextView) listItemView.findViewById(R.id.miwok_text_view);\n miwokWord.setText(currentWord.getMiwokTranslation());\n\n ImageView img = (ImageView) listItemView.findViewById(R.id.img);\n img.setImageResource(currentWord.getImageResourceId());\n return listItemView;\n }\n}\n\n\nmy object structure looks like this:\n\npackage com.example.android.miwok;\n\npublic class Word {\n private String mDefaultTranslation;\n private String mMiwokTranslation;\n private int mImageResourceId;\n\n public Word(String DefaultTranslation, String MiwokTranslation){\n mDefaultTranslation = DefaultTranslation;\n mMiwokTranslation = MiwokTranslation;\n }\n\n public Word(String DefaultTranslation, String MiwokTranslation, int imageResourceId){\n mDefaultTranslation = DefaultTranslation;\n mMiwokTranslation = MiwokTranslation;\n mImageResourceId = imageResourceId;\n }\n\n public String getDefaultTranslation() {\n return mDefaultTranslation;\n }\n\n public String getMiwokTranslation() {\n return mMiwokTranslation;\n }\n\n public int getImageResourceId() {\n return mImageResourceId;\n }\n}\n\n\nas you can see the word object have 2 constructor the first one takes 2 string values and one int value which is an image resource id, the second one takes only 2 String value.\n\nthe code run perfectly with no error which makes me confused because when I use the second object constructor i expected to get an empty list in the activity because the wordAdapter need an image id to work but it works perfectly, any hint guys;"
