  • What electronic scrum/kanban board do you use and recommend for distributed teams?

    - by Derick Bailey
    I have a coworker on a team that is fairly distributed, fairly large (for our company) and wants to take advantage of visual management tools like scrum / kanban boards. Since they are a somewhat distributed team, though, all of the issue management / work management must be done via an electronic tool (we currently use Trac). What issue / work management tools, with a visualization of a scrum / kanban board, do you use for your distributed scrum / kanban teams? would you recommend it, and if so, why?

  • Do you still limit line length in code?

    - by Noldorin
    This is a matter on which I would like to gauge the opinion of the community: Do you still limit the length of lines of code to a fixed maximum? This was certainly a convention of the past for many languages; one would typically cap the number of characters per line to a value such as 80 (and more recnetly 100 or 120 I believe). As far as I understand, the primary reasons for limiting line length are: Readability - You don't have to scroll over horizontally when you want to see the end of some lines. Printing - Admittedly (at least in my experience), most code that you are working on does not get printed out on paper, but by limiting the number of characters you can insure that formatting doesn't get messed up when printed. Past editors (?) - Not sure about this one, but I suspect that at some point in the distant past of programming, (at least some) text editors may have been based on a fixed-width buffer. I'm sure there are points that I am still missing out, so feel free to add to these... Now, when I tend to observe C or C# code nowadays, I often see a number of different styles, the main ones being: Line length capped to 80, 100, or even 120 characters. As far as I understand, 80 is the traditional length, but the longer ones of 100 and 120 have appeared because of the widespread use of high resolutions and widescreen monitors nowadays. No line length capping at all. This tends to be pretty horrible to read, and I don't see it too often, though it's certainly not too rare either. Inconsistent capping of line length. The length of some lines are limited to a fixed maximum (or even a maximum that changes depending on the file/location in code), while others (possibly comments) are not at all. My personal preference here (at least recently) has been to cap the line length to 100 in the Visual Studio editor. This means that in a decently sized window (on a non-widescreen monitor), the ends of lines are still fully visible. I can however see a few disadvantages in this, especially when you end up writing code that's indented 3 or 4 levels and then having to include a long string literal - though I often take this as a sign to refactor my code! In particular, I am curious what the C and C# coders (or anyone who uses Visual Studio for that matter) think about this point, though I would be interested in hearing anyone's thoughts on the subject. Edit Thanks for the all answers - I appreciate the variety of opinions here, all presenting sound reasons. Consensus does seem to be tipping in the direction of always (or almost always) limit the line length. Interestingly, it seems to be in various coding standards to limit the line length. Judging by some of the answers, both the Python and Google CPP guidelines set the limit at 80 chars. I haven't seen anything similar regarding C# or VB.NET, but I would be curious to see if there are ones anywhere.

  • How can a test script inform R CMD check that it should emit a custom message?

    - by mariotomo
    I'm writing a R package (delftfews) here at office. we are using svUnit for unit testing. our process for describing new functionality: we define new unit tests, initially marked as DEACTIVATED; one block of tests at a time we activate them and implement the function described by the tests. almost all the time we have a small amount of DEACTIVATED tests, relative to functions that might be dropped or will be implemented. my problem/question is: can I alter the doSvUnit.R so that R CMD check pkg emits a NOTE (i.e. a custom message "NOTE" instead of "OK") in case there are DEACTIVATED tests? as of now, we see only that the active tests don't give error: . . * checking for unstated dependencies in tests ... OK * checking tests ... Running ‘doSvUnit.R’ OK * checking PDF version of manual ... OK which is all right if all tests succeed, but less all right if there are skipped tests and definitely wrong if there are failing tests. In this case, I'd actually like to see a NOTE or a WARNING like the following: . . * checking for unstated dependencies in tests ... OK * checking tests ... Running ‘doSvUnit.R’ NOTE 6 test(s) were skipped. WARNING 1 test(s) are failing. * checking PDF version of manual ... OK As of now, we have to open the doSvUnit.Rout to check the real test results. I contacted two of the maintainers at r-forge and CRAN and they pointed me to the sources of R, in particular the testing.R script. if I understand it correctly, to answer this question we need patching the tools package: scripts in the tests directory are called using a system call, output (stdout and stderr) go to one single file, there are two possible outcomes: ok or not ok, so I opened a change request on R, proposing something like bit-coding the return status, bit-0 for ERROR (as it is now), bit-1 for WARNING, bit-2 for NOTE. with my modification, it would be easy producing this output: . . * checking for unstated dependencies in tests ... OK * checking tests ... Running ‘doSvUnit.R’ NOTE - please check doSvUnit.Rout. WARNING - please check doSvUnit.Rout. * checking PDF version of manual ... OK Brian Ripley replied "There are however several packages with properly written unit tests that do signal as required. Please do take this discussion elsewhere: R-bugs is not the place to ask questions." and closed the change request. anybody has hints?

    I recently started learning JavaFX. At the moment I can't build any JavaFX project with Java class in Eclipse. For every input I get error "package does not exist" Path to JRE is set in project's properties. Same class compiles if it is Java-project (not JavaFx). What should I check in project settings or Eclipse prefferences?

  • Installing my sdist from PyPI puts the files in the wrong places

    - by Tartley
    Hey. My problem is that when I upload my Python package to PyPI, and then install it from there using pip, my app breaks because it installs my files into completely different locations than when I simply install the exact same package from a local sdist. Installing from the local sdist puts files on my system like this: /Python27/ Lib/ site-packages/ gloopy-0.1.alpha-py2.7.egg/ (egg and install info files) data/ (images and shader source) doc/ (html) examples/ (.py scripts that use the library) gloopy/ (source) This is much as I'd expect, and works fine (e.g. my source can find my data dir, because they lie next to each other, just like they do in development.) If I upload the same sdist to PyPI and then install it from there, using pip, then things look very different: /Python27/ data/ (images and shader source) doc/ (html) Lib/ site-packages/ gloopy-0.1.alpha-py2.7.egg/ (egg and install info files) gloopy/ (source files) examples/ (.py scripts that use the library) This doesn't work at all - my app can't find its data files, plus obviously it's a mess, polluting the top-level /python27 directory with all my junk. What am I doing wrong? How do I make the pip install behave like the local sdist install? Is that even what I should be trying to achieve? Details I have setuptools installed, and also distribute, and I'm calling distribute_setup.use_setuptools() WindowsXP, Python2.7. My development directory looks like this: /gloopy /data (image files and GLSL shader souce read at runtime) /doc (html files) /examples (some scripts to show off the library) /gloopy (the library itself) My MANIFEST.in mentions all the files I want to be included in the sdist, including everything in the data, examples and doc directories: recursive-include data *.* recursive-include examples *.py recursive-include doc/html *.html *.css *.js *.png include LICENSE.txt include TODO.txt My setup.py is quite verbose, but I guess the best thing is to include it here, right? I also includes duplicate references to the same data / doc / examples directories as are mentioned in the MANIFEST.in, because I understand this is required in order for these files to be copied from the sdist to the system during install. NAME = 'gloopy' VERSION= __import__(NAME).VERSION RELEASE = __import__(NAME).RELEASE SCRIPT = None CONSOLE = False def main(): import sys from pprint import pprint from setup_utils import distribute_setup from setup_utils.sdist_setup import get_sdist_config distribute_setup.use_setuptools() from setuptools import setup description, long_description = read_description() config = dict( name=name, version=version, description=description, long_description=long_description, keywords='', packages=find_packages(), data_files=[ ('examples', glob('examples/*.py')), ('data/shaders', glob('data/shaders/*.*')), ('doc', glob('doc/html/*.*')), ('doc/_images', glob('doc/html/_images/*.*')), ('doc/_modules', glob('doc/html/_modules/*.*')), ('doc/_modules/gloopy', glob('doc/html/_modules/gloopy/*.*')), ('doc/_modules/gloopy/geom', glob('doc/html/_modules/gloopy/geom/*.*')), ('doc/_modules/gloopy/move', glob('doc/html/_modules/gloopy/move/*.*')), ('doc/_modules/gloopy/shapes', glob('doc/html/_modules/gloopy/shapes/*.*')), ('doc/_modules/gloopy/util', glob('doc/html/_modules/gloopy/util/*.*')), ('doc/_modules/gloopy/view', glob('doc/html/_modules/gloopy/view/*.*')), ('doc/_static', glob('doc/html/_static/*.*')), ('doc/_api', glob('doc/html/_api/*.*')), ], classifiers=[ 'Development Status :: 1 - Planning', 'Intended Audience :: Developers', 'License :: OSI Approved :: BSD License', 'Operating System :: Microsoft :: Windows', 'Programming Language :: Python :: 2.7', ], # see classifiers http://pypi.python.org/pypi?:action=list_classifiers ) config.update(dict( author='Jonathan Hartley', author_email='[email protected]', url='http://bitbucket.org/tartley/gloopy', license='New BSD', ) ) if '--verbose' in sys.argv: pprint(config) setup(**config) if __name__ == '__main__': main()

  • Hello-World-grade landscape Android app fails to start (complete code included)

    - by WingedCat
    I'm trying to develop a simple Android app, fixed in landscape mode. I am using Eclipse 1.3, compiling for Android SDK version 7 (OS version 2.1). When I try to run it in the emulator, it crashes on boot. (It gets as far as the unlock slider, but shortly after that when trying to launch the application itself, I get "The application Failtest (process com.wcs.failtest) has stopped unexpectedly. Please try again.".) Here is main.xml (with the tags escaped so this displays properly): <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="horizontal" android:layout_width="480px" android:layout_height="320px" > <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="96px" android:layout_height="320px" android:id="@+id/action_menu" > <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="horizontal" android:layout_width="96px" android:layout_height="48px" > <Button android:layout_width="48px" android:layout_height="48px" android:background="#f00" android:id="@+id/action_button_11" /> </LinearLayout> </LinearLayout> </LinearLayout> Here is AndroidManifest.xml (again with the tags escaped so this displays properly): <?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.wcs.failtest" android:versionCode="1" android:versionName="1.0"> <application android:icon="@drawable/icon" android:label="@string/app_name" android:theme="@android:style/Theme.NoTitleBar.Fullscreen"> <activity android:name=".FailtestActivity" android:screenOrientation="landscape" android:label="@string/app_name"> <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> </application> <uses-sdk android:minSdkVersion="7" /> </manifest> And here is FailtestActivity.java: package com.wcs.failtest; import android.app.Activity; import android.os.Bundle; import android.widget.Button; import android.view.View.OnClickListener; import android.view.View; public class FailtestActivity extends Activity { private OnClickListener action11Listener = new OnClickListener() { public void onClick(View v) { } }; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); Button button; button = (Button)findViewById(R.id.action_button_11); button.setOnClickListener(action11Listener); setContentView(R.layout.main); } } I suspect it is something simple I'm overlooking. What is it?

  • Update tile notifcation with XML returned by web service

    - by tempid
    I have a Metro app in C# & XAML. The tile is updated periodically and I've used WebAPI to serve the tile notification XML. So far so good. I was then told that I cannot use WebAPI as the server that I was planning to host it on does not have .NET 4.5. No plans to install it anytime soon either. I had to change the WebAPI to a plain old Web service (.NET 3.5) which does the same thing - return tile notification XML. I've enabled HTTP-GET (I know, security concern) and was able to invoke the webservice like this - http://server/TileNotifications.asmx/[email protected] But ever since I made the switch, the tiles are not being updated. I've checked Fiddler and made sure the app is hitting the webservice and the XML is being returned correctly. But the tiles are not updated. If I replace it with the WebAPI, the tiles are updated. Do I need to do anything special with the web services? like decorating the web method with a custom attribute? Here's my web service code - [WebMethod] public XmlDocument GetTileData(string user) { // snip var xml = new XmlDocument(); xml.LoadXml(string.Format(@"<tile> <visual> <binding template='TileWideSmallImageAndText02'> <image id='1' src='http://server/images/{0}_wide.png'/> <text id='1'>Custom Field : {1}/text> <text id='2'>Custom Field : {2}</text> <text id='3'>Custom Field : {3}</text> </binding> <binding template='TileSquarePeekImageAndText01'> <image id='1' src='http://server/images/{0}_square.png'/> <text id='1'>Custom Field</text> <text id='2'>{1}</text> </binding> </visual> </tile>", value1, value2, value3, value4)); return xml; }

  • Boost Jam vs Jam

    I recently built the Boost libraries in Linux and noticed the package needed an executable called bjam in order to do the build. Is bjam related to jam? If it is related to jam, did they somehow extend (or even dumb-down) bjam? Is it used only for building Boost libraries or is it a general build tool for anything?

  • Why is Microsoft not developing a Halo-like next gen title using C#? [closed]

    - by Joan Venge
    The question might look subjective but considering Microsoft: Owns the Xbox 360 platform Owns the Windows platform Have their own game studio (MGS) Own other 3rd party developers Is a major publisher makes me wonder why Microsoft doesn't push their flagship language to prove that not only you can cut down significant development time, and therefore money, but also show that you can release a next gen title where the real time interactivity doesn't suffer. If Microsoft were to do this once, I am sure many AAA developers would jump on that wagon too.

    H.i everyone, this is my first post here! Anyways, I'm trying to write a "todo list" application. It stores the data in a ContentProvider, which is accessed via a Service. However, my app crashes at launch. My code is below: Manifest file: <?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.examples.todolist" android:versionCode="1" android:versionName="1.0"> <application android:icon="@drawable/icon" android:label="@string/app_name" android:debuggable="True"> <activity android:name=".ToDoList" android:label="@string/app_name" android:theme="@style/ToDoTheme"> <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> <service android:name="TodoService"/> <provider android:name="TodoProvider" android:authorities="com.examples.provider.todolist" /> </application> <uses-sdk android:minSdkVersion="7" /> </manifest> ToDoList.java: package com.examples.todolist; import com.examples.todolist.TodoService.LocalBinder; import java.util.ArrayList; import java.util.Date; import android.app.Activity; import android.content.SharedPreferences; import android.database.Cursor; import android.os.AsyncTask; import android.os.Bundle; import android.view.ContextMenu; import android.content.ComponentName; import android.content.Context; import android.content.Intent; import android.content.ServiceConnection; import android.os.IBinder; import android.view.KeyEvent; import android.view.Menu; import android.view.MenuItem; import android.view.View; import android.view.View.OnKeyListener; import android.widget.AdapterView; import android.widget.EditText; import android.widget.ListView; import android.widget.Toast; public class ToDoList extends Activity { static final private int ADD_NEW_TODO = Menu.FIRST; static final private int REMOVE_TODO = Menu.FIRST + 1; private static final String TEXT_ENTRY_KEY = "TEXT_ENTRY_KEY"; private static final String ADDING_ITEM_KEY = "ADDING_ITEM_KEY"; private static final String SELECTED_INDEX_KEY = "SELECTED_INDEX_KEY"; private boolean addingNew = false; private ArrayList<ToDoItem> todoItems; private ListView myListView; private EditText myEditText; private ToDoItemAdapter aa; int entries = 0; int notifs = 0; //ToDoDBAdapter toDoDBAdapter; Cursor toDoListCursor; TodoService mService; boolean mBound = false; /** Called when the activity is first created. */ public void onCreate(Bundle icicle) { super.onCreate(icicle); setContentView(R.layout.main); myListView = (ListView)findViewById(R.id.myListView); myEditText = (EditText)findViewById(R.id.myEditText); todoItems = new ArrayList<ToDoItem>(); int resID = R.layout.todolist_item; aa = new ToDoItemAdapter(this, resID, todoItems); myListView.setAdapter(aa); myEditText.setOnKeyListener(new OnKeyListener() { public boolean onKey(View v, int keyCode, KeyEvent event) { if (event.getAction() == KeyEvent.ACTION_DOWN) if (keyCode == KeyEvent.KEYCODE_DPAD_CENTER) { ToDoItem newItem = new ToDoItem(myEditText.getText().toString(), 0); mService.insertTask(newItem); updateArray(); myEditText.setText(""); entries++; Toast.makeText(ToDoList.this, "Entry added", Toast.LENGTH_SHORT).show(); aa.notifyDataSetChanged(); cancelAdd(); return true; } return false; } }); registerForContextMenu(myListView); restoreUIState(); populateTodoList(); } private void populateTodoList() { // Get all the todo list items from the database. toDoListCursor = mService. getAllToDoItemsCursor(); startManagingCursor(toDoListCursor); // Update the array. updateArray(); Toast.makeText(this, "Todo list retrieved", Toast.LENGTH_SHORT).show(); } private void updateArray() { toDoListCursor.requery(); todoItems.clear(); if (toDoListCursor.moveToFirst()) do { String task = toDoListCursor.getString(toDoListCursor.getColumnIndex(ToDoDBAdapter.KEY_TASK)); long created = toDoListCursor.getLong(toDoListCursor.getColumnIndex(ToDoDBAdapter.KEY_CREATION_DATE)); int taskid = toDoListCursor.getInt(toDoListCursor.getColumnIndex(ToDoDBAdapter.KEY_ID)); ToDoItem newItem = new ToDoItem(task, new Date(created), taskid); todoItems.add(0, newItem); } while(toDoListCursor.moveToNext()); aa.notifyDataSetChanged(); } private void restoreUIState() { // Get the activity preferences object.

When I run the program, LogCat shows that the NullPointerException occurs in populateTodoList(), at toDoListCursor = mService.getAllToDoItemsCursor(). mService is the Cursor object returned by TodoService. I've added the service to the Manifest file, but I still cannot find out why it's causing an exception. Thanks in advance.
