"Gradle: How to make a compile scope file dependency excluded in packaging?",
"I have a multi-module gradle project with the following basic structure:\n\nroot\n core\n c-interface\n m-interface\n\n\nThe c-interface and m-interface both depend on the core project:\n\ncompile project(':root:core')\n\n\nc-interface and m-interface use the WAR plugin, but core does not and is just a jar.\n\nIn the core project, I am pulling in some file system dependencies with the following. One of these dependencies I cannot have packaged in the WARs generated by c-interface and m-interface. Previously I had this dependency in a nexus maven repository so I could exclude it by group,name,version in a providedRuntime configuration in c-interface and m-interface. \n\nI cannot figure out how to do the same for the file dependency. The gradle dependencies task does not list file dependencies so I don't know what I would put in a providedRuntime.\n\nI read http://issues.gradle.org/browse/GRADLE-471 but trying to use the idea there doesn't seem to remove the archive from my packages. Here is what I am currently defining (in core's build.gradle):\n\ncompile fileTree(dir: 'dependencies/compile/archive', include: '*.jar', exclude: 'management.jar')\ncompile(files('dependencies/compile/archive/management.jar')){ notPackaged = true } // Excludes it from all publications\n\n\nUpdate\n\nprovidedCompile without war plugin looked like a possibility. I set this up in the core build.gradle and it compiled fine, but c-interface and m-interface also needed the dependency at compile time. Including the file as providedCompile (or even a sanity check with compile) in c-interface and m-interface did not fix compile time errors related to missing the management.jar dependency. My speculation is because it was already scoped as providedCompile in core that the new declarations are ignored in c-interface and m-interface. \n\ncore/build.gradle:\n\nconfigurations { providedCompile }\n\ndependencies {\n providedCompile files('dependencies/compile/archive/management.jar')\n}\n\nsourceSets.main.compileClasspath += configurations.providedCompile\nsourceSets.test.compileClasspath += configurations.providedCompile\nsourceSets.test.runtimeClasspath += configurations.providedCompile\n\n\nc-interface/build.gradle:\n\nprovidedCompile files('dependencies/compile/archive/management.jar')"

These styles are getting overwritten by the styles that are on the page, causing undesired effects. \n\nI know that I can fix this by using !important on all of my styles, but I really don't want to do this. Is there any way to do this w/o using !important?"

When enterEvent() occurs, the left half of the button (icon/text) becomes a QLineEdit, while the right half is still a drop down menu.\n\nI have been trawling through whatever forums google search brings up, and while I loosely understand how to paint it, how do I connect the events properly? If I paint the QLineEdit, how do I get that part of the custom widget to act and respond like a QLineEdit? (Python preferred, C++ is ok)\n\n[QComboBox will not work, and definitely the other widgets I'd like to create don't have any approximate equivalent. Also, I know I can build a widget with other simpler widgets, and then mess with the style sheets to achieve something similar looking, but I know there is an answer to the above, because Qt does it, and it would have better cross-system styling then writing custom style sheets.]"

"Binding a UserControl to a custom BusyIndicator control",
"I have a requirement to focus on a specific textbox when a new view is loaded.\n\nThe solution was to add this line of code to the OnLoaded event for the view:\n\nDispatcher.BeginInvoke(() => { NameTextBox.Focus(); });\n\n\nSo this worked for one view, but not another. I spent some time debugging the problem and realized that the new view I was working on had a BusyIndicator that takes focus away from all controls since the BusyIndicator being set to true and false was occuring after the OnLoaded event.\n\nSo the solution is to call focus to the NameTextBox after my BusyIndicator has been set to false. My idea was to create a reusable BusyIndicator control that handles this extra work. However, I am having trouble doing this in MVVM.\n\nI started by making a simple extension of the toolkit:BusyIndicator:\n\npublic class EnhancedBusyIndicator : BusyIndicator\n{\n public UserControl ControlToFocusOn { get; set; }\n\n private bool _remoteFocusIsEnabled = false;\n public bool RemoteFocusIsEnabled\n {\n get\n {\n return _remoteFocusIsEnabled;\n }\n set\n {\n if (value == true)\n EnableRemoteFocus();\n }\n }\n\n private void EnableRemoteFocus()\n {\n if (ControlToFocusOn.IsNotNull())\n Dispatcher.BeginInvoke(() => { ControlToFocusOn.Focus(); });\n else\n throw new InvalidOperationException(\"ControlToFocusOn has not been set.\");\n }\n\n\nI added the control to my XAML file with no problem:\n\n<my:EnhancedBusyIndicator\n ControlToFocusOn=\"{Binding ElementName=NameTextBox}\"\n RemoteFocusIsEnabled=\"{Binding IsRemoteFocusEnabled}\"\n IsBusy=\"{Binding IsDetailsBusyIndicatorActive}\"\n...\n> \n...\n <my:myTextBox (this extends TextBox)\n x:Name=\"NameTextBox\"\n ...\n />\n...\n</my:EnhancedBusyIndicator>\n\n\nSo the idea is when IsRemoteFocusEnabled is set to true in my ViewModel (which I do after I've set IsBusy to false in the ViewModel), focus will be set to NameTextBox. And if it works, others could use the EnhancedBusyIndicator and just bind to a different control and enable the focus appropriately in their own ViewModels, assuming their views have an intial BusyIndicator active.\n\nHowever, I get this exception when the view is loaded:\n\nSet property 'foo.Controls.EnhancedBusyIndicator.ControlToFocusOn' threw an exception. [Line: 45 Position: 26]\n\nWill this solution I am attempting work? If so, what is wrong with what I have thus far (cannot set the ControlToFocusOn property)?\n\n\n\nUpdate 1\n\nI installed Visual Studio 10 Tools for Silverlight 5 and got a better error message when navigating to the new view. Now I gete this error message:\n\n\"System.ArgumentException: Object of type System.Windows.Data.Binding cannot be converted to type System.Windows.Controls.UserControl\"\n\nAlso, I think I need to change the DataContext for this control. In the code-behind constructor, DataContext is set to my ViewModel. I tried adding a DataContext property to the EnhancedBusyIndicator, but that did not work:\n\n<my:EnhancedBusyIndicator\n DataContext=\"{Binding RelativeSource={RelativeSource Self}}\"\n ControlToFocusOn=\"{Binding ElementName=NameTextBox}\"\n RemoteFocusIsEnabled=\"{Binding IsRemoteFocusEnabled}\"\n IsBusy=\"{Binding IsDetailsBusyIndicatorActive}\"\n...\n>\n\n\n\n\nUpdate 2\n\nI need to change UserControl to Control since I will be wanting to set focus to TextBox objects (which implement Control). However, this does not solve the issue."

"How can gnome-keyring be modified to require quality master passwords?",
"I am using CentOS 7. I have certain password quality requirements set up in pwquality.conf (related to the libpwquality package). In addition to these complexity constraints being applied to user logins, I'd like them to be applied to a Password Keyring's master passwords, as accessed e.g. via seahorse and the gnome-keyring-daemon, so that users cannot use weak passwords to protect their keyrings. I'm not concerned about the passwords inside the keyrings, just the passwords for the keyrings themselves.\n\nI have figured out how to make a call to the libpwquality API, particularly pwquality_check is the function I want. However, I am having difficulty retrieving the password in plaintext in the code, in order to pass it to pwquality_check. For example, in the code near gkd-secret-create.c line 211, if I try to capture the password that should be returned by gcr_prompt_password_finish, I only get a NULL.\n\ngchar *password;\n\npassword = gcr_prompt_password_finish (GCR_PROMPT (source), result, &error);\n\n// password is NULL\n\n\nI've stepped through all the code I can find in a debugger and am coming up empty: the password seems to be obscured away very well, or already hashed and discarded by this point. How can I get the password from this prompt and send it to libpwquality? Or is there a better way to enforce password complexity on GNOME's password manager/keyring?"

"I am having issues with my tableviewcell's image appearing to flicker. I know what is causing the issue, I am just not sure of the best way to get around it.\n\nI am using Parse.\n\nThe flickering is caused by using the cache policy CacheThenNetwork, so the query checks the cache and then checks the network for any changes. This results in the query being run multiple times, and therefore the cellForRowAtIndexPath is called multiple times.\n\nIn cellForRowAtIndexPath, I set the image to nil to avoid duplicate images when the cells are dequeued. This is one of the main reasons that the flickering happens, and if it wasn't set to nil then the image wouldn't be disappearing and appearing again each time the query is called.\n\nSo my question is, is there a better way to handle the caching or the cellForRowAtIndexPath so that I can avoid this apparent flickering?\n\nI need to use this particular cache policy as it works best for what I am doing.

"git marks files as deleted",

I can still work on them, but when I want to commit changes, it just deletes my files from the project. Is this something that I am doing, or is it a Git bug?\n\nLater Edit:\nThis happens in NetBeans. Running git status from the command line is ok, but in NB they are marked as deleted and they get deleted upon commit"

"Possible memory leak in Square/Picasso for Android",
"I am part of a team developing a commercial media app. Part of the functionality is to allow the user to customise a ViewGroup montage of ImageViews with their own images retrieved either from Gallery or direct from Camera. I am using the following Picasso call to do this:\n\n mPicasso.load(uri)\n .resize(newWidth, newHeight)\n .into(container);\n\n\nwhere mPicasso is Picasso.with(appContext()) and newWidth and newHeight are dimensions calculated from the source height and width such that aspect ratio is maintained and the resulting image is 1MP. Typically, the sources are between 8 and 16MP.\n\nIf I have a montage of say, eight ImageViews, and I keep adding images to each one in turn, the app eventually crashes. Device only has so much memory, right? Eventually if you keep adding infinite images you're going to run out. What really concerns me, however, is that the app will crash half-way through replacing the eight images. To be clear, you've added your eight images and you've gone back to the top and started replacing those images with different ones and you get to roughly the fourth before the crash.\n\nI would have expected that once an image has been replaced, the old one would be cleaned up. I can fix this by reducing the max size down to 100KP but the problem with that is I imagine I am just delaying the crash. Furthermore, the user has the ability to zoom the image and with such a low resolution, it starts to look knarly quite quickly.\n\nI have posted the crash log here:-\nhttps://gist.github.com/mylesbennett/452c992f6912039ea62d\nbecause it's too long to paste direcly in stackoverflow.\n\nAny suggestions of workarounds/ fixes etc. would be greatly appreciated.\n\n(the crash point in TemplateImageView.isScaleInitialised is where the app is attempting to allocate memory to a nine-value float array:\n\nfloat[] values = new float[9];\n\n\nso I am guessing that this is just the straw that broke the camel's back)"

"How to save a 4D image series to a single DICOM file using ITKTools?",

"SQL: Getting day specific totals when totals are summed per week",

Every row has the complete total of that week, along with the individual totals of each day of the week. So those five totals add up to the weektotal. \nEvery row also has the week of the year in it (format: yyyyww).\n\nso it would look like this for example\n\nid|date |total|totalsu|totalmo|totaltu|totalwe|totalth|totalfr|totalsa\n-----------------------------------------------------------------------\n 1|201921| 50.0| 00.0 | 10.0 | 10.0 | 10.0 | 10.0 | 10.0 | 0.0 |\n 2|201922| 60.0| 00.0 | 15.0 | 10.0 | 15.0 | 10.0 | 10.0 | 0.0 |\n 3|201923| 70.0| 30.0 | 5.0 | 10.0 | 10.0 | 10.0 | 5.0 | 0.0 |\n 4|201924| 50.0| 00.0 | 10.0 | 10.0 | 10.0 | 10.0 | 10.0 | 0.0 |\n\n\nNow my question is, how would i get all of the totals from let's say wednesday in the week 201921 to tuesday in the week 201924 within one query? It would be great if I could get it within one query, but if it's absolutely impossible, two or three should be fine as well.\nThe expected output would be 180 if my math is correct."

"Fill parent div with image element",
"I want to fill a parent div with a img, but instead of setting the image as a background property of the div, I want it to be a individual img element inside of the div.\n\nIn other words, I want to do this:\n\ndiv {\n background-image: url('someimg.jpg');\n background-size: cover;\n background-repeat: no-repeat;\n}\n\n\n..but with a img element, like this:\n\n<div>\n <!-- Image element should cover the container on dekstops and small screens as well -->\n <img src=\"someimg.jpg\">\n</div>\n\n\nI managed to do something like this on the img:\n\nimg {\n width: 100%;\n max-height: 100%;\n object-fit: fill;\n}\n\n\n..but on resize, it doesn't fill the parent. Here's a fiddle: https://jsfiddle.net/dy5ub0f5/5/"

"Numpy 2d array, obtain indexes of rows where specified column indexes equal 1",
"I have a 2d numpy array like so, which will only ever have 0, 1 values.\n\na = np.array([[1, 0, 1, 0], # Indexes 0 and 2 == 1\n [0, 1, 1, 0], # Indexes 1 and 2 == 1\n [0, 1, 0, 1], # Indexes 1 and 3 == 1\n [0, 1, 1, 1]]) # Indexes 1, 2, and 3 == 1\n\n\nWhat I'd like to do is to get the indices of every row where a pair of column indexes passed are all equal to 1. \n\nFor example, if the function doing this is get_rows, get_rows(a, [1, 3]), should return [2, 3], because the rows at indexes 2 and 3 have column indexes 1 and 3 equal to 1. Similarly, get_rows(a, [1, 2]) should return [1, 3]. \n\nI know how to do this in a Pandas dataframe, but I'd like to stick to using pure numpy for this one. I tried using np.where in some form like \n\nnp.where( ((a[i1 - 1] == 1) & (a[i2 - 1] == 1) ))\n\n\nbut this doesn't seem to give me what I want, and wouldn't work for varying number of passed indices."

"How to boost a SOLR document when indexing with /solr/update",
"To index my website, I have a Ruby script that in turn generates a shell script that uploads every file in my document root to Solr. The shell script has many lines that look like this:\n\n curl -s \\\n \"http://localhost:8983/solr/update/extract?literal.id=/about/core-team/&commit=false\" \\\n -F \"myfile=@/extra/www/docroot/about/core-team/index.html\"\n\n\n...and ends with:\n\ncurl -s http://localhost:8983/solr/update --data-binary \\\n'<commit/>' -H 'Content-type:text/xml; charset=utf-8'\n\n\nThis uploads all documents in my document root to Solr. I use tika and ExtractingRequestHandler to upload documents in various formats (primarily PDF and HTML) to Solr.\n\nIn the script that generates this shell script, I would like to boost certain documents based on whether their id field (a/k/a url) matches certain regular expressions. \n\nLet's say that these are the boosting rules (pseudocode):\n\nboost = 2 if url =~ /cool/\nboost = 3 if url =~ /verycool/\n# otherwise we do not specify a boost\n\n\nWhat's the simplest way to add that index-time boost to my http request?\n\nI tried:\n\ncurl -s \\\n \"http://localhost:8983/solr/update/extract?literal.id=/verycool/core-team/&commit=false\" \\\n -F \"myfile=@/extra/www/docroot/verycool/core-team/index.html\" \\\n -F boost=3\n\n\nand:\n\ncurl -s \\\n \"http://localhost:8983/solr/update/extract?literal.id=/verycool/core-team/&commit=false\" \\\n -F \"myfile=@/extra/www/docroot/verycool/core-team/index.html\" \\\n -F boost.id=3\n\n\nNeither made a difference in the ordering of search results. What I want is for the boosted results to come first in search results, regardless of what the user searched for (provided of course that the document contains their query). \n\nI understand that if I POST in XML format I can specify the boost value for either the entire document or a specific field. But If I do that, it isn't clear how to specify a file as the document contents. Actually, the tika page provides a partial example:\n\ncurl \"http://localhost:8983/solr/update/extract?literal.id=doc5&defaultField=text\" \\\n--data-binary @tutorial.html -H 'Content-type:text/html'\n\n\nBut again it isn't clear where/how to specify my boost. I tried:\n\ncurl \\ \n\"http://localhost:8983/solr/update/extract?literal.id=mydocid&defaultField=text&boost=3\"\\\n--data-binary @mydoc.html -H 'Content-type:text/html'\n\n\nand\n\ncurl \\ \n\"http://localhost:8983/solr/update/extract?literal.id=mydocid&defaultField=text&boost.id=3\"\\\n--data-binary @mydoc.html -H 'Content-type:text/html'\n\n\nNeither of which altered search results.\n\nIs there a way to update just the boost attribute of a document (not a specific field) without altering the document contents? If so, I could accomplish my goal in two steps:\n1) Upload/index document as I have been doing\n2) Specify boost for certain documents"

"Using a class library assembly that internally uses a link to a global assembly info file",
"I am struggling with the current scenario below. I'm using vs 2010 and C# with .NET 4:\n\n\nI have a separate solution (call it solution A) that has 2 class library projects in it (call them B and C).\nProject B has a link to a \"GlobalAssemblyInfo.cs\" file in Project C, BUT Project B does not depend on Project C, it merely just has a link to the .cs file in Project C.\nThis is all well and good as everything compiles and B.dll + C.dll is produced.\nNow I have a totally different solution (call it D) that has only 1 console application project in it (call it E).\nNow in Project E, I add a reference to B.dll. When I compile all is well.\n\n\nThe problem is when I debug Project E, when I get to a line of code that uses any object from Project B (or B.dll), I get an error that says \"FileNotFoundException unhandled exception. Could not load file or assembly B\", where B is the fully qualified name of assembly B.\n\nHow do I resolve this problem? I know the problem is caused by the linking to the \"GlobalAssemblyInfo.cs\" file in Project C because when I remove / delete this link everything works fine and I can use object in assembly B.\n\nHere is a url that explains how to link to files within a solution / project if you need to understand what linking is http://bloggingabout.net/blogs/jschreuder/archive/2006/11/02/Centralizing-AssemblyInfo-settings_2C00_-or-simplify-versioning-of-solutions.aspx"

"Make Espresso wait for WebView to finish loading",
"Is there a reliable way to make Espresso wait for WebViews to finish loading?\n\nI've tried the approach outlined here but found it unreliable. It also has other drawbacks:\n\n\nIt relies on replacing the WebView's WebChromeClient. Any existing WebChromeClient can't be wrapped either, since WebViewrt doesn't have a getWebChromeClient() method for some reason.\nIt requires a specific WebView instance, so every time I start an Activity with a WebView I have to get the WebView instance and register a new WebviewIdlingResource for it.\n\n\nI'm hoping someone has a solution without any of these drawbacks. I had hopes that the espresso-web package might provide a solution, but it doesn't appear to offer anything relating to loading."
