"Put tmp files in an external dir with Ember?",
"In Ember.js projects I always find it so disruptive that ember server creates such a massive dump of rapidly changing files to the tmp folder in my project directory. \n\nI often create projects in a cloud-synced folder, so these files tend to hit my daemon over the head with a mallet. \n\nAlso, it messes up my IDE's indexing and I have to manually exclude it every time. \n\nIs there a way to configure to run ember s to put tmp outside of my project directory? Putting it into /tmp or ~/.tmp would be great."

"Why does UIView.StringSize need to run on the UI thread?",
"If I run UIView.StringSize from within some async code like a Task.ContinueWith, it will blow up with a UIKitThreadAccessException because that method starts with a call to UIApplication.EnsureUIThread ("Go to declaration" in MonoDevelop; I'm not sure the license allows me to post it here).\nTask.Factory.StartNew(() => {\n // Blows up discretely...nothing written to application output.\n // Also blows up for UIViews that exist only in code (not rendered).\n SizeF textSize = someView.StringSize(someString, someFont, new SizeF(someView.Bounds.Width, float.MaxValue), UILineBreakMode.WordWrap);\n Console.WriteLine(textSize);\n});\n\nIf I wrap this simplified version in InvokeOnMainThread, all is well, but I definitely have times when I want to measure some text without that call. As well, I fully understand the exception's purpose and it has saved me a bunch of hassle when called something deep within async code before, but in this case the use of EnsureUIThread here seems unnecessary. If I simply restate that call as a hit on the NSString class, it will happily run outside the UI thread.\nTask.Factory.StartNew(() => {\n // Outputs expected size data: "{Width=##, Height=##}".\n using (NSString nssSomeString = new NSString(someString)) {\n SizeF textSize = nssSomeString.StringSize(someFont, new SizeF(someView.Bounds.Width, float.MaxValue), UILineBreakMode.WordWrap);\n Console.WriteLine(textSize);\n }\n});\n\nThe code for UIView.StringSize appears to do roughly the same NSString work and there doesn't appear to be anything blatantly UI-thread-oriented. Is there something I am missing that would require this version of the method to be called from the UI thread?\nEdit (2013-01-17):\nI filed a bug with Xamarin just to see their response. It sounds like they are looking into marking this method as ThreadSafe."

"Ways to download multiple patches in Android Application?",
"I'm pretty new to Android so excuse me for uncertainty.\n\nI have been reading quite a lot about Android lately and have come across the idea of using expansion files with them (.obb) and their use as patches. But I guess there is only one patch file which can be uploaded with any Android Application on the Play Store. (Correct me if I'm wrong)\n\nI have an idea which can help minimise the app size and give users full flexibility to control what they need. When you first install my app, it will have all the basic functions required for the app to work (example: code for performing a specific function) Then if the user tries to perform another option, the app will connect online and will know how to handle the event. (This will be worked out later)\n\nBut, in the settings menu I want to give users a choice. They can check all the modules they want offline, so that my app doesn't need to connect online for those particular modules. If they check, for example, two modules, then their .java files will be downloaded and their data will be used next time instead of the app going online.\n\nI want to know if this is possible or not. If yes, how and where do I make my app download the additional .java files and how do I implement their inclusion in the current app. Is there a workaround for this flexibility?\n\nComment if you need more details."

"Why not validate a Camel Uri using java.net.URI",
"I had a colleague ask me, why I don't create the uris for a camel component (consumer/producer) using javas URI class:\n\nfrom(java.net.URI.create(someUriString).toString())\n\n\nThe reason this might make sense is, that there is automatic validation for the given uri, before it is interpreted by camel (when the uri is in part loaded from a configuration file, some validation could be useful).\n\nThe thing is, that I have never seen anybody create a camel uri like this, everybody just uses plain Strings.\nIs there a reason, why we never use java.net.URI to validate a uri for camel, or is there even a drawback in doing it?"

After some research, I found a way to get the CPU usage of a process (reading /proc/[PID]/stat/ information) but I couldn't find a way to go to the package level (a process can run many packages).\n\nI'd say it's impossible to do given that the SDK doesn't offer such APIs to monitor CPU usage (as it does with memory usage) but I'd rather know what you think about this.\n\nThank you!"

"How to use Wicket's DownloadLink with a file generated on the fly?",
"DownloadLink is nice and handy for creating a button/link for downloading a file, along these lines:\n\nadd(new DownloadLink(\"downloadButton\", getReportFile(), \"report.pdf\"));\n\n\nand\n\n<input type=\"button\" wicket:id=\"downloadButton\" value=\"Download\" />\n\n\nHowever, I would like to trigger the generation of the file to download only when the button/link is clicked. In other words, upon click, I'd call a method that generates the file (a Pentaho report in our case), puts it in a temp place and returns a File pointing to it. Then I'd tell the DownloadLink to use that File. Question is, is this possible somehow? \n\nCurrently we have something like the code below, which works, but I'm interested in whether DownloadLink could be used instead.\n\nadd(new Link<Void>(\"downloadButton\") {\n @Override\n public void onClick() {\n IResourceStream resourceStream = new AbstractResourceStreamWriter() {\n @Override \n public void write(OutputStream output) {\n try {\n reportService.generateReport(output, report);\n } catch (IOException e) {\n // ...\n }\n }\n\n @Override\n public String getContentType() { \n return CONTENT_TYPE_PDF;\n }\n };\n\n getRequestCycle()\n .setRequestTarget(new ResourceStreamRequestTarget(resourceStream)\n .setFileName(\"report.pdf\"));\n }\n});\n\n\n(Wicket 1.4.18, if it makes a difference.)"

"How can I make textarea border the same as text input border?",
"I would like to have the textarea fields in my form appear the same as the text input fields, cross-browser. And I don't want to be forcing a custom style - I would like to just use whatever the standard style is within the user's browser.\n\nSo I know I could use\n\ntextarea {\n border-style: inset;\n border-width: 2px;\n}\n\n\nand then they would match in Chrom[e,ium], but then they don't match on Firefox/Iceweasel, for example.\n\nSo is there a straightforward way to say to the browser \"please render textarea elements with whatever border you are using for input[type=\"text\"]\"?"

"Java to Javascript/HTML5 Canvas",
"I was wondering what the java to javascript/HTML5 translations were for these things:\n1. Switching Activities/Layouts\n2. Methods\n3. Scanner Method (input via text box)\n\nI am writing a game basically that is written in javascript and HTML5. HTML5 is being purely used to display the graphics via canvas. I am trying to create a menu for my game, but I was wondering how I would switch to another layout once I click the play button."

"Upload file - Protractor",
"I fight with protractor because for some tests I need to UPLOAD file. My HTML looks like:\n\n<div class=\"panel-footer\">\n <ul class=\"list-unstyled\">\n <!-- ngRepeat: file in imagesToUpload --> \n </ul>\n <button class=\"btn btn-sm btn-success pull-right ng-binding ng-hide\" ng-show=\"imagesToUpload.length\" ng-click=\"uploadImages()\">Nahrát na server</button>\n <button class=\"btn btn-sm btn-primary ng-binding\" ng-file-select=\"onImageSelect($files)\" data-multiple=\"true\" style=\"overflow: hidden;\">Vybrat soubory<input type=\"file\" class=\"btn btn-sm btn-primary ng-binding\" ng-file-select=\"onImageSelect($files)\" data-multiple=\"true\" multiple=\"multiple\" __wrapper_for_parent_=\"true\" style=\"width: 1px; height: 1px; opacity: 0; position: absolute; padding: 0px; margin: 0px; overflow: hidden;\"></button>\n </div>\n\n\nINPUT HTML:\n\n<input type=\"file\" class=\"btn btn-sm btn-primary ng-binding\" ng-file-select=\"onImageSelect($files)\" data-multiple=\"true\" multiple=\"multiple\" __wrapper_for_parent_=\"true\" style=\"width: 1px; height: 1px; opacity: 0; position: absolute; padding: 0px; margin: 0px; overflow: hidden;\">\n\n\nI search a lot about this issue in protractor. And basicly people advise was to COPY / PASTE path to file to input and then click \"UPLOAD\"\n\nIn my case there is a problem becuase input is here but it store some object not PATH\n\nIf I pick file manualy it store in HTML like:\n\n<li ng-repeat=\"file in imagesToUpload\" class=\"ng-binding ng-scope\">\n FileName.png <span title=\"remove\" class=\"btn btn-flat glyphicon glyphicon-remove\" ng-click=\"imagesToUpload.splice($index, 1)\"></span>\n </li>\n\n\nMaybe this is really stupid but I am thinking if there isnt some other way how to do this? Maybe create object and send it there or something else?\n\nAny advice is welcome."

"What's the best way to extract text from pdf in python without changing the layout and format?",
"I want text with exact format and layout from pdf.\nIf pdf to text is not the direct choice, is it possible to do pdf -> xml -> text? \nI have already tried PyPDF2, pdfminer and pdftotxt. Even I've tried using AWS textract and got incorrect layout.\nBasically if I can construct sentence from the text extracted from pdf, that's enough.\nI used Zamzar API which gives exact output but they're quiet expensive. \nAny possible solution?"

"Decrypt data within a node/express.js Route",
"I have an app where I am trying to encrypt the userID before sending it to the client side. The reason for doing this is because I am using EJS as a tempting engine which means I have code where I am using the userID like so:\n\n<body ng-init=\"getAllPosts('<%= user._id' %>)\"></body>\n\n\nThe issue with this is that when someone does \"inspect element\" on any browser they can clearly see their userID. See image below for example:\n\n\n\nTo fix this issue I started Encrypting my userID before I sent to the client, like s0:\n\napp.get('/profile',isLoggedIn,function(req, res) {\n\n var user = req.user;\n var uid = encrypt(JSON.stringify(user._id));\n\n res.render('profile.ejs', {\n userID: uid\n }); \n});\n\n\nThis Encrypts the ID successfully as you can see in the image below:\n\n\n\nThe Issue:\n\nThe issue is that I can successfully Decrypt the ID but even after decrypted it I can't get the data from the database. I have tried copy pasting the decrypted ID into my route and that gets the data successfully. Its like it does not read the decrypted ID from the variable but works when copy paste it myself.\n\nHeres the code:\n\napp.get('/user/posts/:id', isLoggedIn, function(req, res){\n\n var x = decrypt(req.params.id)\n\n Posts.findOne({userID:x}, function(err, post){\n if(err)\n console.log(err);\n else if(post){\n res.json(post);\n } else if(!post){\n res.json({message: \"No Posts document exists for this user\"});\n } \n });\n });\n\n\nThing to note is that the variable x contains decrypted ID is text form!\n\nJust for more info here are my Encrypting & Decrypting functions:\n\n//Encrypt Data\n function encrypt(text){\n\n var cipher = crypto.createCipher(algorithm,key)\n var crypted = cipher.update(text, 'utf8', 'base64')\n crypted += cipher.final('base64');\n\n console.log(\"CRYPTED \" + crypted);\n return crypted;\n }\n\n//Decrypt Data\nfunction decrypt(text){\n\n var decipher = crypto.createDecipher(algorithm,key)\n var dec = decipher.update(text, 'base64', 'utf8')\n dec += decipher.final('utf8');\n\n console.log(\"DECRYPTED \" + dec);\n return dec;\n}\n\n\nOutput of Decrypt Function:"
