"AD Microsoft Login 400 bad request headers too long ASP.net MVC",
"My asp.net mvc application works as expected on localhost and logs in on every browser with ease. I am using Azure Active directory to log in to the application, I published my application to a web server and now I get a 400 bad request from every browser.\n\nI have tried clearing the cache with no luck.\nI increased the maxRequest and time.\n\n<httpRuntime targetFramework=\"4.6.1\" maxRequestLength=\"2097151\" executionTimeout=\"2097151\"/>\n\n\nI noticed that the browser is attempting to log in but the request is sent over 40 times. I managed to get it working sometimes but once the request is sent to microsoft.login I get the same error.\n\nDoes anyone know of a solution to my problem?\n\nThanks in advance, Adam."

"Scala- How can I read some specific bytes from a file?",
"I'd like to encrypt a text(about 1 MB) and I use the max length of RSA keys(4096 bits). However, the key seems too short. As I googled, I got to know that the max size of text that a RSA can encrypt is 8 bytes shorter than the length of the key. Thus, I can only encrypt 501 bytes in this way. So I decided to divide my text into 2093 arrays (1024*1024/501=2092.1).The question is how can I pour the first 501 bytes into the first array in scala?Anyone who can help me this out?"

"Text input has focus but doesn't update what I type until after I scroll",
"I have a page with an HTML5 video. When I open the Bootstrap modal login dialog with the page scrolled to zero, everything works as expected. When I scroll down the page or open the dialog after scrolling, the username and password input boxes sort of freeze: I can enter text but I won't see it until after I scroll again. The blinky caret will also freeze unless I'm scrolling around the page. If I remove the video tag then everything works fine. This only happens in Chrome (I'm using Version 38.0.2125.104 m).

Convert to XNA rotation/translation matrix (AForge uses OpenGL matrix form):\n\n float yaw, pitch, roll;\n marker1Rot.ExtractYawPitchRoll(out yaw, out pitch, out roll);\n\n Matrix xnaRot = Matrix.CreateFromYawPitchRoll(-yaw, -pitch, roll);\n Matrix xnaTranslation = Matrix.CreateTranslation(marker1Trans.X, marker1Trans.Y, -marker1Trans.Z);\n Matrix transform = xnaRot * xnaTranslation;\n\n\n4. Find 3D coordinates of the corners:\n\n //Model corner points\n cornerModel = new Vector3[]\n {\n new Vector3(halfCornerSize,0,-halfCornerSize),\n new Vector3(-halfCornerSize,0,-halfCornerSize),\n\n new Vector3(halfCornerSize,0,halfCornerSize),\n new Vector3(-halfCornerSize,0,halfCornerSize)\n };\n\n Matrix markerTransform = Matrix.CreateTranslation(cornerModel[i].X, cornerModel[i].Y, cornerModel[i].Z);\n cornerPositions3d1[i] = (markerTransform * transform).Translation;\n\n //DEBUG: project corner onto screen - represented by brown dots\n Vector3 t3 = viewPort.Project(markerTransform.Translation, projectionMatrix, viewMatrix, transform);\n cornersProjected1[i].X = t3.X; cornersProjected1[i].Y = t3.Y;\n\n\n5. Look at the 3D distance between two corners on a marker, this represents 100mm. Find the scaling factor needed to convert this 3D distance to 100mm. (I actually get the average scaling factor):\n\n for (int i = 0; i < 4; i++)\n {\n //Distance scale;\n distanceScale1 += (halfCornerSize * 2) / Vector3.Distance(cornerPositions3d1[i], cornerPositions3d1[(i + 1) % 4]);\n }\n distanceScale1 /= 4;\n\n\n6. Finally I find the 3D distance between related corners and multiply by the scaling factor to get distance in mm:\n\n for(int i = 0; i < 4; i++)\n {\n distance[i] = Vector3.Distance(cornerPositions3d1[i], cornerPositions3d2[i]) * scalingFactor;\n }\n\n\nThe distances acquired are never truly correct. I used the cutting board as it allowed me easy calculation of what the distances should be. The above image calculated a distance of 147mm (expected 150mm) for corner 1 (red to purple). The image below shows 188mm (expected 200mm). \n\n\n\nWhat is also worrying is the fact that when measuring the distance between marker corners sharing an edge on the same marker, the 3D distances obtained are never the same. Another thing I noticed is that the brown dots never seem to exactly match up with the colored dots. The colored dots are the coordinates used as input to the CoPlanar posit. The brown dots are the calculated positions from the center of the marker calculated via POSIT.\n\nDoes anyone have any idea what might be wrong here? I am pulling out my hair trying to figure it out. The code should be quite simple, I don't think I have made any obvious mistakes with the code. I am not great at maths so please point out where my basic maths might be wrong as well..."

"I'm working on a build for an old project that wasn't maintained well at all; it's more or less a hodgepodge of hundreds of independent projects that get cobbled together. Naturally, that means there's a lot of inappropriate things going on.\n\nThere's probably 50-100 executables, and around 300 shared/static libraries. Some of the libraries are built with the -mt flag (sun studio; -pthreads appears to be the gcc equivalent), others aren't.\n\nThis seems potentially problematic to me. Suppose I have libA.so and libB.so -- A was built with -mt, but not B. I expect if the application linked against A & B is single-threaded there won't be any problems (feel free to correct me on that). However, if the app is threaded then this situation opens a fun can of worms.\n\nI'm inclined to just build everything with -mt and have done with it. Most of the office agrees with this plan, but there's one dissenter. My expectation is that this will just create a potential degradation in performance, but at the moment performance is already abysmal because of the poor state of this project; so I'm not worried about that.\n\nIn short: are there any potential pitfalls with doing this?"

"Why does TStringList have BeginUpdate and EndUpdate?",
"I understand that using BeginUpdate and EndUpdate on VCL controls such as TListBox speeds up the process of populating the control with Items as it prevents the control from being repainted, until EndUpdate is called.\n\nExample:\n\nprocedure TForm1.AddItems;\nvar\n i: Integer;\nbegin\n Screen.Cursor := crHourGlass;\n try\n for i := 0 to 5000 do\n begin\n ListBox1.Items.Add('Item' + IntToStr(i));\n end;\n finally\n Screen.Cursor := crDefault;\n end;\nend;\n\n\nThe above will have a delay because the Listbox is allowed to be repainted, but the delay can be shorted by preventing repainting like so:\n\nprocedure TForm1.AddItems;\nvar\n i: Integer;\nbegin\n Screen.Cursor := crHourGlass;\n try\n ListBox1.Items.BeginUpdate;\n try\n for i := 0 to 5000 do\n begin\n ListBox1.Items.Add('Item' + IntToStr(i));\n end;\n finally\n ListBox1.Items.EndUpdate;\n end;\n finally\n Screen.Cursor := crDefault;\n end;\nend;\n\n\nNow I tested this using a TStringList:\n\nprocedure TForm1.AddItems;\nvar\n SL: TStringList;\n i: Integer;\nbegin\n SL := TStringList.Create;\n try\n Screen.Cursor := crHourGlass;\n try\n SL.BeginUpdate;\n try\n for i := 0 to 5000 do\n begin\n SL.Add('Item' + IntToStr(i));\n end;\n finally\n SL.EndUpdate;\n end;\n\n ListBox1.Items.Assign(SL);\n finally\n Screen.Cursor := crDefault;\n end;\n finally\n SL.Free;\n end;\nend;\n\n\nIt seems that regardless if the TStringList uses BegindUpdate and EndUpdate, the list is populated at approximately the same speed..\n\nAre they really needed though as the TStringList is performed in memory and not visually. Should I use BeginUpdate and EndUpdate on a TStringList anyway, is it good practice to do this?\n\nI feel silly for asking this but why does the TStringList have the procedures BeginUpdate and EndUpdate?\n\nI think I may have answered my own question here, either way I would like to hear your views.\n\nThanks :)"

"Android: Find location from location name. Is Android's geocoder the correct way?",
"I am trying to build a location based application which shows google map and allows the user to search a location by writing an address (as google maps does).\n\nI have been trying to use android's geocoder to do this, and it finds some addresses. However, one of the first addresses that i tried (vaasankatu, helsinki, finland), it didn't find when I searched by street name (vaasankatu). Also one other street name that I have tried does not return any results. If I add the city (helsinki), or the country (finland) after the street name, then geocoder finds addresses.\n\nGoogle maps web app and android app find the addresses without any problem just by searching by the street name. I am wondering whether I could somehow make geocoder to return the address when it is searched by the street name? I could of course try to find out the current city with the geocoder and attach it after the query, but this seems a bit like a hack, is there a better way?\n\nI am also a bit worried about the geocoder documentation, which says: \n\n\n \"The Geocoder class requires a backend service that is not included in\n the core android framework. The Geocoder query methods will return an\n empty list if there no backend service in the platform. Use the\n isPresent() method to determine whether a Geocoder implementation\n exists.\"\n\n\nI don't quite understand what that means.. So is there a big portion of phones that don't support geocoder? The text seems to suggest there might be, but why would there be such an api then at all..? Should I use another api alltogether? Is, for example Google geocoding api for web services usually used? Or places api?"

"Line breaks in TMemo on a form with Default button",
"I have a form in an application written using FireMonkey. On that (modal) form there's an OK button for which I have set Default property to True. There's also a memo component. Now if type press enter while typing in the memo, then the form is closed instead of inserting line break into memo.\n\nWhat I would like to accomplish, is that when enter (or shift+enter or smth like that) is pressed in memo component, then line break is enter. In other components, where you cannot type line breaks, I would still like hitting enter to close the form. The best I have found thus far is adding following code into forms OnCloseQuery action:\n\nif (Focused.GetObject.ClassName = 'TMemo') and (ModalResult = mrOk) then\nbegin\n CanClose := False;\n Memo := TMemo(Focused.GetObject);\n Memo.InsertAfter(Memo.CaretPosition, sLineBreak, [TInsertOption.ioMoveCaret,\n TInsertOption.ioCanUndo]);\nend\nelse\n CanClose := True;\n\n\nThis works, but there's now there's a small annoying delay after hitting enter and before the line break appears. Also I would like solution, that would be less hacky.\n\nI should also point out, that I also have forms which contain the OK button, but not the memo component, however a memo will be moved to that form at runtime by changing its parent property."

"I am using PureLayout to put a UISlider between 2 buttons as below:\n\n\n[self.slider autoPinEdge:ALEdgeLeading toEdge:ALEdgeTrailing ofView:self.leftButton withOffset:10.0f];\n[self.slider autoPinEdge:ALEdgeTrailing toEdge:ALEdgeLeading ofView:self.rightButton withOffset:10.0f];\n[self.slider autoAlignAxisToSuperviewAxis:ALAxisHorizontal];\n\n\nIs it possible that the UISlider automatically sets its width between the leftButton and the rightButton ?"

"Declaring a Brushes variable for input",
"I currently have the following method\n\npublic void printTitle(string title){\n // settings for stringformat\n g.DrawString(title, drawFontTitle, Brushes.White, x, y, stringFormatTitle);\n}\n\n\nHowever, I am trying to let the input define the color of the title, like so:\n\npublic void printTitle(string title, Brushes titleColor){\n // settings for stringformat\n g.DrawString(title, drawFontTitle, titleColor, x, y, stringFormatTitle);\n}\n\n\nAnd it would be used like this:\n\nprintTitle(\"Title Text\", Brushes.White);\n\nHowever, I think there is an issue when declaring the Brushes titleColor that's causing an error."
