"Incorrect Base URL for Application",
"I have an ASP.net MVC app, built using the ASPnet Module Zero framework. For some reason all of the page URLs seem to be prefixed with /Account/Login, even when I'm already logged in. For example, the login page's URL is:\n\nlocalhost:62114/Account/Login/Account/Login\n\n\nOnce logged in, the one application page is\n\nlocalhost:62114/Account/Login/App/ListAllAccount\n\n\nTrying to access any page without the /Account/Login in the URL, automatically causes an Error 404. appsettings.json looks like this:\n\n\"App\": {\n \"WebSiteRootAddress\": \"http://localhost:62114/\",\n \"CorsOrigins\": \"http://localhost:62114\"\n},\n\n\nThe route configuration looks as follows:\n\n routes.MapRoute(\n name: \"default\",\n template: \"{controller=Home}/{action=Index}/{id?}\");\n\n routes.MapRoute(\n name: \"defaultWithArea\",\n template: \"{area}/{controller=Home}/{action=Index}/{id?}\");\n\n\nAll of the services and resources also use the correct URLs, which means that you actually cannot log in, as you cannot access the service URLs.\n\nEDIT: One thing that I noticed now is that it is only when I debug the application locally. Once published, the issue seems to go away."

"How to implement min left/right in css",
"I have an element in my css which look like below\n\n.xyz{\n position:absolute;\n left:50%;\n }\n\n\nNow as expected when I reduce the width of browser window, this element moves towards left. However I want it to stop at a certain point since otherwise it starts overlapping other elements. In principle, this is very similar to min-height and and min-width properties. But there is no such property like min-left or min-top. How can I implement this."

"Search for substring matches in a file bash",

"how to tap into PostgreSQL DDL parser?",
"The DDL / SQL scripts used to create my PostgreSQL database are under version control. In theory, any change to the database model is tracked in the source code repository. \n\nIn practice however, it happens that the structure of a live database is altered 'on the fly' and if any client scripts fail to insert / select / etc. data, I am put in charge of fixing the problem.\n\nIt would help me enormously if I could run a quick test to verify the database still corresponds to the creation scripts in the repo, i.e. is still the 'official' version.\n\nI started using pgTAP for that purpose and so far, it works great. However, whenever a controlled, approved change is done to the DB, the test scripts need changing, too.\n\nTherefore, I considered creating the test scripts automatically. One general approach could be to\n\n\nrun the scripts to create the DB\naccess DB metadata on the server\nuse that metadata to generate test code\n\n\nI would prefer though not having to create the DB, but instead read the DB creation scripts directly. I tried to google a way to tap into the DDL parser and get some kind of metadata representation I could use, but so far, I have learned a lot about PostgreSQL internals, but couldn't really find a solution to the issue.\n\nCan someone think of a way to have a PostgreSQL DDL script parsed ?"

"How to limit results with same field value to X amount of documents every time it shows up multiple times in a row",
"I have an issue that I am not quite sure how to solve. Really hope someone here can help me figure out how to go about it.\n\nImagine that I have 100 documents, all with user_id fields. I know that most documents are from different user_ids, but documents 1-10 and 20-29 are from the same user_id.\n\nWhat I want to do, is make sure that I only see the the latest two documents whenever a the same user_id is returned in a row more than twice. So if user_id 1 shows up more than twice in a row, I want to limit those documents. I want this to happen every time it happens for that user_id, not limit it completely after that.\n\n\n\nIf I just request all documents as they are indexed now, I would get a result like: \n\n[1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, ...]\n\n\n\nWhat I am loooking for, us a way to make sure these groups of 1s, are limited to two documents in a row, like so: \n\n[1, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 1, 1, 12, ...] \n\nNotice that 1, 1, ..., 1, 1, ... happens here, meaning that the rows of identical user ids have been cut down to two, instead of removing them all together, which would result in something like:\n\n[1, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, ...] \n\n\n\nI also want this to work if the request is paginated (Multiple queries). \n\nSo imagine that I request the first two pages, with a size of 5, then I would like to get:\n\nPage1: [1, 1, 2, 3, 4]\n\nPage2: [5, 6, 7, 8, 9]\n\nInstead of:\n\nPage1: [1, 1, 2, 3, 4]\n\nPage2: [1, 1, 1, 1, 1]\n\n\n\nI hope that I have described the issue well enough for someone to understand.

However, by some meta data we get before we are about to instantiate a new instance, we decide if it needs a bigger instance to begin with. so instead of 10% CPU limit, we want a 20% CPU limit.\n\nOur placement service will then use the following method to create a new instance of that VotingDataType service. fabricClient.ServiceManager.CreateServiceAsync(...). However, we're not able to customize the Parameters for the ResourceGovernancePolicy. \n\nIs there a way to dynamically set the parameters or resource policies for ServicePackageResourceGovernancePolicy and/or ResourceGovernancePolicy when we create a new instance of a certain ServiceType at runtime?"

I am trying to extract interval where the value switched from 0 to 1.\n\nMy ideal out put in above case would be : \n\n[['2020-09-11 00:00:00', '2020-09-20 00:00:00'],\n ['2020-08-12 00:00:00', '2020-08-16 00:00:00']]\n\n\nHow I am approaching:\nI am iterating over the df in reverse and trying to find first occurrence of '1'. \nThere after I am looking for first occurrence of 0. These correspond to the first interval.\nI am repeating above over the df.\n\nBut, the output, I am getting is:\n\n[['2020-09-11 00:00:00', '2020-09-20 00:00:00'],\n ['2020-08-12 00:00:00', '2020-08-22 00:00:00']]\n\n\nI know that the issue is because of consecutive 1 in the timeseries. But, not able to find the workaround. Any leads would be appreciated."

"Chrome font-face not loading local font",
"I am running into an odd issue. Using the webfont link through google's webfonts api works just fine and loads the font, however... The app i'm creating is local only, so having any kind of overhead connecting to the internet is noticeable when rendering the fonts for the first time, plus no font would be loaded if there is no internet connection.\n\n@font-face {\nfont-family: Pt Sans;\nfont-style: normal;\nfont-weight: 400;\nsrc: url(http://themes.googleusercontent.com/static/fonts/ptsans/v4/jduSEW07_j4sIG_ERxiq4Q.woff);\n}\n\n\nThe above is the working code.\n\n@font-face {\nfont-family: Pt Sans;\nfont-style: normal;\nfont-weight: 400;\nsrc: url(fonts/ptsans.woff);\n}\n\n\nThis works when running directly from the browser locally, however i'm using a framework which embeds the chrome webview into my C# application, called CefSharp. The difference is, i'm simulating a link to a site, rather then loading the pages directly. It would be as if I created my own http:// link to the font, like the webfont.\n\nIf I open up Chromes dev tools > resources tab > fonts and click the locally loaded font, it shows a default font, however if I click the font loaded through google's api, it renders the correct font.\n\nWhat is the google api sending to the browser that i'm not?

Unfortunately, I wasn't able to figure out the exact conditions that reveal the effect. Try the README.md file of the Visible bookmarks extension. I'm sorry for asking do download some specific files to observe the effect, but I don't know the other way.\n\nIf you're still not scared away then open the README.md file and turn on the highlight-parentheses mode:\n\nM-x highlight-parentheses-mode RET\n\n\nThen press and hold the down-arrow key. The pointer will start moving down line-by-line. But when it leaves the line 45 (which is at the bottom of the screen at the moment) it suddenly jumps back to the middle of the screen (line 24). W-what!?\n\nAnd it happens every time you approach line 46 when it is right below the bottom edge of the screen. Moreover, it seems to effect other extensions too (e.g. visual bookmarks start to make strange things like messing up the bookmarks order).\n\nI'm new to elisp so I hardly can find a bug in the source of these three modes.

Which approach do people recommend? \n\nDoes anyone have videos/program demos they found useful and could recommend to me?

"Minimising number of calls to std::max in nested loop",
"I'm trying to reduce the number of calls to std::max in my inner loop, as I'm calling it millions of times (no exaggeration!) and that's making my parallel code run slower than the sequential code. The basic idea (yes, this IS for an assignment) is that the code calculates the temperature at a certain gridpoint, iteration by iteration, until the maximum change is no more than a certain, very tiny number (e.g 0.01). The new temp is the average of the temps in the cells directly above, below and beside it. Each cell has a different value as a result, and I want to return the largest change in any cell for a given chunk of the grid.\n\nI've got the code working but it's slow because I'm doing a large (excessively so) number of calls to std::max in the inner loop and it's O(n*n). I have used a 1D domain decomposition\n\nNotes: tdiff doesn't depend on anything but what's in the matrix\n\nthe inputs of the reduction function are the result of the lambda function\n\ndiff is the greatest change in a single cell in that chunk of the grid over 1 iteration\n\nblocked range is defined earlier in the code\n\nt_new is new temperature for that grid point, t_old is the old one\n\nmax_diff = parallel_reduce(range, 0.0,\n //lambda function returns local max\n [&](blocked_range<size_t> range, double diff)-> double\n {\n for (size_t j = range.begin(); j<range.end(); j++)\n {\n for (size_t i = 1; i < n_x-1; i++)\n {\n t_new[j*n_x+i]=0.25*(t_old[j*n_x+i+1]+t_old[j*n_x+i-1]+t_old[(j+1)*n_x+i]+t_old[(j-1)*n_x+i]);\n tdiff = fabs(t_old[j*n_x+i] - t_new[j*n_x+i]);\n diff = std::max(diff, tdiff);\n } \n }\n return diff; //return biggest value of tdiff for that iteration - once per 'i'\n },\n //reduction function - takes in all the max diffs for each iteration, picks the largest\n [&](double a, double b)-> double\n {\n convergence = std::max(a,b);\n return convergence;\n }\n );\n\n\nHow can I make my code more efficient? I want to make less calls to std::max but need to maintain the correct values. Using gprof I get:\n\nEach sample counts as 0.01 seconds.\n % cumulative self self total \n time seconds seconds calls ms/call ms/call name \n 61.66 3.47 3.47 3330884 0.00 0.00 double const& std::max<double>(double const&, double const&)\n 38.03 5.61 2.14 5839 0.37 0.96 _ZZ4mainENKUlN3tbb13blocked_rangeImEEdE_clES1_d\n\n\nETA: 61.66% of the time spent executing my code is on the std::max calls, it calls over 3 million times. The reduce function is called for every output of the lambda function, so reducing the number of calls to std::max in the lambda function will also reduce the number of calls to the reduce function"

"It is possible to configure functions with subtype overloading?",
"When using CREATE TABLE it is possible to declare varchar(12), varchar(34) or varchar datatypes, and it will be different...\n\nBut when declaring a function, the \"subtype\" is ignored... No warning (!)... I see that to ignore is a good thing, the function signature is essential to manage function overloading, and \"subtype signatures\" will be a something chaotic to manage... But I not see in the Guide (also nothing at typeconv-func), no Guide's warning about it, no explanation. \n\nSo, in nowadays, 2018, after all PostgreSQL v10+ enhancements... Can I configure PostgreSQL to accept function overloading with subtypes? \n\n\n\nConcrete example\n\nCREATE TABLE foo ( x varchar(12), y varchar(34), z varchar );\n\\d foo\n-- not ignored, as expected \n\nCREATE OR REPLACE FUNCTION foo( p_x varchar ) RETURNS text AS \n$f$ SELECT 'hello1' $f$ LANGUAGE SQL IMMUTABLE;\nCREATE OR REPLACE FUNCTION foo( p_x varchar(12) ) RETURNS text AS \n$f$ SELECT 'hello10' $f$ LANGUAGE SQL IMMUTABLE;\n\n\\df foo\n List of functions\n Schema | Name | Result data type | Argument data types | Type \n--------+------+------------------+-----------------------+--------\n public | foo | text | p_x character varying | normal\n (1 row)\n\n\nSo it is impossible to declare foo(x) that not do the same tham foo(z)... \n\n SELECT pg_typeof(x),pg_typeof(y),pg_typeof(z) FROM foo;\n -- returns \"character varying\" for all\n\n\n\n\nOf course, sometimes we can use pg_typeof():\n\n\nWith VARCHAR(s) is impossible to check s.\nWith PostGIS's geometry is possible to check subtype (e.g. POINT subtype). It is an overload workaround, but not \"real overload\". \n\n\n\n\nNOTE: the parsing error with the commented foo('abc') will be solved with adequate \"orthogonal overloading function set\". In the example, with \n\nCREATE FUNCTION foo( p_x text ) RETURNS text AS $f$ SELECT 'hello-text' \n$f$ LANGUAGE SQL IMMUTABLE;\n\n\nthe \"automatic cast abc to text\" solve the problem select foo('abc') is working."

I am trying to compare two date vectors in R (not originally input as date vectors) to: return the first value if the second is NA and the first is not missing; to return the largest of the two dates if the second is not missing; or to return NA if both values are missing. For example, for data presented below, I'd like lastdate to compute as follows:\n\nv1 v2 lastdate\n1/2/2006 NA 1/2/2006\n1/2/2006 12/2/2006 12/2/2006\nNA NA NA\n\n\nI have written a formula to avoid looping over each row (85K in these data) as follows:\n\nlastdate <- function(lastdate1,lastdate2){\n if (is.na(lastdate1)==T & is.na(lastdate2)==T) {NA}\n else if (is.na(lastdate2)==T & !is.na(lastdate1)) {as.Date(lastdate1,format=\"%m/%d/%Y\")}\n else {max(as.Date(lastdate2,format=\"%m/%d/%Y\"),as.Date(lastdate1,format=\"%m/%d/%Y\"))}\n}\ndfbobs$leaveobsdate <- lastdate(as.Date(dfbobs$leavedate1,format=\"%m/%d/%Y\"),as.Date(dfbobs$leavedate2,format=\"%m/%d/%Y\"))\n\n\nThe last line is telling it to compare two vectors of dates, but is not quite right as I am getting the errors\n\nWarning messages:\n1: In if (is.na(lastdate1) == T & is.na(lastdate2) == T) { :\n the condition has length > 1 and only the first element will be used\n2: In if (is.na(lastdate2) == T & !is.na(lastdate1)) { :\n the condition has length > 1 and only the first element will be used\n\n\nI'm sure this is very silly and there's probably a much easier way to do this, but any help would be appreciated.\n\nEDIT: I have now attempted this with an ifelse function to deal with the vectors, as suggested, but the comparison, while working if I type in single values (e.g., lastdate(\"1/1/2006\",\"1/2/2006\")), produces NAs if I try it on the dataframe vectors. The code follows: \n\nlastdate <- function(lastdate1,lastdate2){\nifelse(is.na(lastdate1==T) & is.na(lastdate2==T), NA, \n ifelse(is.na(lastdate2)==T & !is.na(lastdate1), as.Date(lastdate1,format=\"%m/%d/%Y\"), \n ifelse(!is.na(lastdate2) & !is.na(lastdate1), max(as.Date(lastdate2,format=\"%m/%d/%Y\"),as.Date(lastdate1,format=\"%m/%d/%Y\")),NA)))\n}\ndfbobs$leaveobsdate <- as.Date(lastdate(as.Date(dfbobs$leavedate1,format=\"%m/%d/%Y\"),as.Date(dfbobs$leavedate2,format=\"%m/%d/%Y\")),origin=\"1970-01-01\")"
