"AWS: Is it possible to allow a Lambda function call an API secured by WAF?",

Now, I have a Lambda function that should call this API, and of course if getting a Forbidden error. I know I can solve this if I put the Lambda inside a VPC and then add the VPC IPs to the WAF rule, however is it possible to make it works WITHOUT using the VPC?"

"QML - Imperative code not supported",
"Can someone comment on the fact that for QML, any imperative JavaScript code is not executed unless it is part of an extra component. I am facing such kind of problem when I include the following code to my QML:\n\nfunction qmlSlot(text){\n page.data=text\n if(page.data===\"received\")\n page.color=\"black\";\n}\n\n\nAs the Qt Designer get frozen and shows the following warning:\n\n\n Imperative code is not supported in the Qt Quick Designer\n\n\nI read that building qmlpuppet installs an executable for rendering components in the /bin directory of the Qt building it. Qt Quick Designer checks for the Qt of the current project if a qmlpuppet is in the /bin directory. If yes it takes the qmlpuppet provided by the Qt version instead of the one provided by Qt Creator itself. In my case I haven't used the Qt static binary install, but instead built Qt from the source, thus qmlpuppet executable was generated and is already located at:\n\n/usr/local/Qt-5.2.1/qtcreator/bin\n-rwxr-xr-x 1 qml2puppet\n-rwxr-xr-x 1 qmlpuppet\n\n\nSo, the executable qmlpuppet is placed where is expected to be found and still this annoying message continues.\n\nThe workaround I took at moment is to comment out any so called \"Imperative code\" for when I want to edit the front-end QML using Qt Designer. Then after take out those comments to have the \"Imperative code\" activated again. But this is very annoying, although the code compile and works as I expected it to behave. \n\nSo, should I get worried about this warning? Anyway, there is some mean to get rid of this problem, as it froze the Qt Designer?"

"Regular expression to remove repeated slashes that are after a specific word (VBScript/Classic ASP)",
"I'm struggling here, trying to figure out how to replace all double slashes that come after a specific word.\n\nExample: \n\n<img alt=\"\" src=\"/pt/webf//2015//47384_1.JPG\" height=\"235\" width=\"378\" />\n<div>Don't remove this // or this//</div>\n\n\nI want the string above to look like this:\n\n<img alt=\"\" src=\"/pt/webf/2015/47384_1.JPG\" height=\"235\" width=\"378\" />\n<div>Don't remove this // or this//</div>\n\n\nNotice the double slashes have been replaced with just one slash in the img tag but left unscathed in the div tag. I only want to replace the double slashes IF they come after the word: pt. \n\nI tried something like this:\n\n(?=pt)((.*?)\\/\\/)+ \n\n\nHowever, the first thing wrong with it is (?=) does not do pattern backtracking, as far as I'm aware. That is, it'll only look for the first matching pattern. The second thing wrong with it is it doesn't work as I intended it to.\n\nhttps://regex101.com/r/kC4tA5/1\n\nOr maybe I'm going about this the wrong way, since regular expression support is not expansive in VBScript/Classic ASP and I should try to break up the string and process, instead of trying to do everything in one regular expression???\n\nAny help would be appreciated.\n\nThank you."

So the JQM pages need to be created dynamically.\n\nFrom the UI perspective, I plan to use a fixed footer containing the dots(based on the number of pages).\n\nThe problem is with the view-model which needs to persist between the JQM pages, as I do not want to load data from the server by page, data is loaded at once and it is expected that the client will display it in pages.\n\nI could have a view-model holding the data and living through-out the life of the application and just bind each page view to it.\nInstead, I want to keep the view-model alive as long as it's really required by the view.\n\nThe solution I am thinking is to catch jQueryMobile page navigation events and see if the navigation is between these pages.\nIf it's not, the view-model should be removed(assigning it to null).\nNext time if any of these pages needs to be loaded(for example by navigating back to the last page), the view model is re-created(data is fetched from web-site again).\n\nIs there a better approach?"

"Can I serve .html files using Razor as if they were .cshtml files without changing the extension of all my pages?",
"I manage a large asp.net site which has previously been converted from static html site to asp.net. \n\nFor several reasons (mainly SEO) we decided not to rename all the files to .aspx back when we originally converted the site. This was very easy to do by simply adding the buildProvider and httpHandler to the web.config.\n\n<buildProviders>\n <add extension=\".html\" type=\"System.Web.Compilation.PageBuildProvider\"/>\n</buildProviders>\n\n<httpHandlers>\n <add path=\"*.html\" verb=\"*\" type=\"System.Web.UI.PageHandlerFactory\"/>\n</httpHandlers>\n\n\nNow I am upgrading the site to use Asp.net WebPages with Razor cshtml files. I can rename all the files if necessary, and use url rewriting to make the urls stay the same, however it would be much easier if I could just configure the web.config to tell it to parse .html files as if they were .cshtml.\n\nI have searched around quite a bit, and could not find anything equivalent to the PageHandlerFactory for razor pages. It appears as though it is just an internal mechanism in the .net 4.0 ISAPI handler.\n\nThe site is currently running on Windows 2003 server and IIS 6. We will be upgrading to 2008/IIS 7.5 in the near future, but I'd prefer not to wait for that.\n\nIs there any way to get the .html files to be parsed by razor as if they were .cshtml files?"

But when I rotate the tube and reset it to original position, the tube is properly getting back to original position but text is randomly facing to any direction.\n\nMy basic requirement is the text should always face the user.

"Efficient expanding OLS in pandas",
"I would like to explore the solutions of performing expanding OLS in pandas (or other libraries that accept DataFrame/Series friendly) efficiently.\n\n\nAssumming the dataset is large, I am NOT interested in any solutions with a for-loop;\nI am looking for solutions about expanding rather than rolling. Rolling functions always require a fixed window while expanding uses a variable window (starting from beginning);\nPlease do not suggest pandas.stats.ols.MovingOLS because it is deprecated;\nPlease do not suggest other deprecated methods such as expanding_mean.\n\n\nFor example, there is a DataFrame df with two columns X and y. To make it simpler, let's just calculate beta.\nCurrently, I am thinking about something like\n\nimport numpy as np\nimport pandas as pd\nimport statsmodels.api as sm\n\ndef my_OLS_func(df, y_name, X_name):\n y = df[y_name]\n X = df[X_name]\n X = sm.add_constant(X)\n b = np.linalg.pinv(X.T.dot(X)).dot(X.T).dot(y)\n return b\n\ndf = pd.DataFrame({'X':[1,2.5,3], 'y':[4,5,6.3]})\n\ndf['beta'] = df.expanding().apply(my_OLS_func, args = ('y', 'X'))\n\n\nExpected values of df['beta'] are 0 (or NaN), 0.66666667, and 1.038462.\n\nHowever, this method does not seem to work because the method seems very inflexible. I am not sure how one could pass the two Series as arguments.\nAny suggestions would be appreciated."

I'm not looking to match on ID. Instead I wand to run through the data frame entirely. Output should look something like:\n\n\n ID Times Between\n \n 1 32239.76 0\n \n 2 32241.14 1\n \n 3 68138.72 0\n \n 4 111233.93 0\n \n 5 128395.28 0\n \n 6 146180.31 1\n \n 7 188433.35 0\n \n 8 198714.7 0\n\n\nAlternatively, knowing if any of my 'possible' time values fall within 2 seconds of start or end times would also do the trick (also with 1/0 outputs)\n\n(Thanks for the feedback on the original post)\n\nThanks in advance for your patience with me as I navigate this system."
