"Close HTML tags in truncated string",
"I have an ASP.NET page that displays a number of blog posts one after another. I don’t want to print the whole blog posts but only a set number of characters with a Read More link. Every post is saved as html in database from where it gets loaded. I currently strip all the html tags off from the post and display the set number of characters (e.g first 300) but I eventually lose all the styling. If I don’t strip the tags off then the truncated post gets various unclosed html tags which break the page especially on IE. The blog posts are entered through a different system of which I don’t have any control over. To overcome this issue, I have written a method that takes the html in a string adds all opening tags to an array list and as soon as a tag is closed removes it from the end of the array list so at the end the array list is only left with opening tags that have not closed. I check for those tags and replace each tag with its closing tag. Then I add all these closing tags to a string and append the string to the actual html string. When adding opening tags to the string I ignore all tags that include /> to avoid self closing tags. This is doing the job for me but my method is prone to bugs as html string is not predictable. Is there a better way around this issue ?"

"Why isn't SparseArray in Android JFC compatible?",
"So, I'm supposed to use SparseArray instead of HashMap for the sake of performance:\n\nHowever, SparseArray isn't a part of JCF and does not implement Collection nor List nor Map. HashMap, on the other hand, implements Map and provides values() that I can work with when needing JCF-compatible behavior. For example, using it in an ArrayAdapter and various custom sorting (for values).\n\nMy question is three-fold:\n\n\nWhy doesn't SparseArray implement JCF interfaces? I mean,\nwhat is the motivation for not implementing these interfaces in\nlight of the fact that most of the methods are already there?\nAre there alternatives to SparseArray that implement JCF interfaces\nor can easily be converted and retain the SparseArray performance?\nAre HashMaps with a few hundred elements really that much\nslower? Are my users really going to notice?\n\n\nI'm looking for answers with depth and I prefer to have references to authoritative sites. If you think you know why SparseArray was not implemented with JCF interfaces, show some support, help me understand. If you think I should be using SparseArray, show me how to use it with ArrayAdapter and custom sorting (Comparator-esque solutions preferred). If there are better alternatives, links to the API doc, library or tutorial would be helpful. If you think I should stick with HashMaps, explain why the performance benefit of SparseArray is outweighed by the needs of the interfaces."

"Conditional properties for include paths break IntelliSense editing?",
"I have a build where some include and library paths must differ based on whether the build is 32-bit or 64-bit, and must be parameterised for easy editing by the user. I'm using property sheets to deal with that requirement.\n\nAfter learning of conditional properties I thought I'd try to get rid of the hack of using per-platform property sheets to set macros based on values from the master property sheet (e.g. set PGBASEDIR from $(PGBASEDIR_x64) on x64, and $(PGBASEDIR_x86) on x86; for details see the answer to the question linked above). \n\nI switched to using conditional properties in my msbuild target file instead, but found that while the build its self worked, VS's editor couldn't find the include files whose path is specified by the conditional properties. The same is true if I set the properties in a conditional property group in the property sheet .props file, or add individual conditional properties to the main property group.\n\nSo I've tried this in both the msbuild target file:\n\n<PropertyGroup Condition=\"'$(Platform)' == 'x64'\">\n <PGBASEDIR>$(PGBASEDIR_x64)</PGBASEDIR>\n</PropertyGroup>\n<PropertyGroup Condition=\"'$(Platform)' == 'Win32'\">\n <PGBASEDIR>$(PGBASEDIR_x86)</PGBASEDIR>\n</PropertyGroup>\n\n\nand have also tried adding the same to the property sheet file that's included in all build configurations/platforms. Same result. I also tried using individual conditional properties within the main <PropertyGroup Label=\"UserMacros\"> block for the property sheet; again, same effect.\n\nWhen I examine the macros list in a Visual Studio by going to a project property, editing it, and tabbing open the MACROS> list in the UI, I see the macros that're defined statically in the property sheet, but not the conditional macros.\n\nI tried adding <BuildMacro> entries to the master property sheet's <ItemGroup> in case that was the issue, e.g.:\n\n<BuildMacro Include=\"PGBASEDIR\">\n <Value>$(PGBASEDIR)</Value>\n</BuildMacro>\n\n\n\n\n... but saw no change.\n\nIn all cases the build its self runs fine, but Visual Studio's editor complains that it can't find the headers (and therefore anything defined within them).\n\nIf I stick with stacked property sheets it works, e.g.:\n\n\npg_sysdatetime project\n\n\nRelease | win32\npg_sysdatetime.props\n\n <PropertyGroup Label=\"UserMacros\">\n <PGMAJORVERSION>9.2</PGMAJORVERSION>\n <PGBASEDIR_x64>$(PROGRAMW6432)\\PostgreSQL\\$(PGMAJORVERSION)</PGBASEDIR_x64>\n <PGBASEDIR_x86>$(MSBUILDPROGRAMFILES32)\\PostgreSQL\\$(PGMAJORVERSION)</PGBASEDIR_x86>\n </PropertyGroup>\n <PropertyGroup />\n <ItemDefinitionGroup />\n <ItemGroup>\n <BuildMacro Include=\"PGMAJORVERSION\">\n <Value>$(PGMAJORVERSION)</Value>\n </BuildMacro>\n <BuildMacro Include=\"PGBASEDIR_x64\">\n <Value>$(PGBASEDIR_x64)</Value>\n </BuildMacro>\n <BuildMacro Include=\"PGBASEDIR_x86\">\n <Value>$(PGBASEDIR_x86)</Value>\n </BuildMacro>\n </ItemGroup>\n\npg_sysdatetime_x86.props\n\n\ndefines <PGBASEDIR>$(PGBASEDIR_x86)</PGBASEDIR>\n\nRelease | x64\npg_sysdatetime.props\n\n\n... same as above ...\n\npg_sysdatetime_x64.props\n\n\ndefines <PGBASEDIR>$(PGBASEDIR_x64)</PGBASEDIR>\n\n\n\n\nI'm using Visual Studio 2012 Express."

"Polymer.Dart's floating label for PaperInput not visible",
"I have the example code in my Angular.Dart component:\n\n<paper-input bind-value=\"value\" label=\"MyLabel\" floatingLabel></paper-input>\n\nThe paper input shows the value that is in my Angular.Dart component, but the floatingLabel does not appear. However, upon clicking the input, the label appears with the standard animation as if it was hidden. It seems as though this is a bug with the \"constructor\" of the paper-input element. I expected the floating label to appear above the input field when text is in the input field regardless if it was newly created or not. Is there a way to fix this glitch?\n\n\n\nProgress: (github.com/Polymer/paper-input/issues/117)\n\nI am looking intensively at the issue listed above, however implementing the fix accordingly is not as easy. As suggested by @GünterZöchbauer, I can use the dart:js library. However it appears that the solution was designed specifically for PolymerJs and not particularly for PolymerDart. Maybe I am overthinking things, but I am unable to perform a simple port. \n\nBut the issue does bring up a good point. The element is unable to detect the change (for what ever reason). So something needs to poke it to trigger an update. I currently have the dart context to the Element, however the class (paper-input is the class) does not contain the method inputAction upon inspection with WebStorm. However assuming that the inputAction method was firing an event, I can simply use the dispatchEvent method. However which event will trigger the event without modifying the object itself? And not crashing the browser would be great (I have been crashing the webpage with Chrome's Aw, snap! blue screen of death with some event tests)."

"Write depth buffer from Cg and then read it from OpenGL",
"I'd like to create a shadow map with cg. I have written an opengl program and 2 pixel shaders (with 2 vertex shader). In the first pixel shader, I write the DEPTH register, and in the OpenGL program I read this to a texture. In the second pixel shader I'd like to read from this texture, however it seems to contain only 0 values. There is another texture in both shaders, I don't know if that van be a problem, but I don't think so.\n\nThe first shader is like this:\n\nvoid main( in float3 point : TEXCOORD0,\n out float3 color : COLOR,\n out float depth : DEPTH)\n {\n // here I calculate the distances (c)\n color = float3(c, c, c);\n depth = c;\n }\n\n\nIn the OpenGL program I created a texture for the depth component:\n\n glGenTextures(1, &shadowtex_id);\n glBindTexture(GL_TEXTURE_2D, shadowtex_id);\n glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_NEAREST);\n glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_NEAREST);\n glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_S, GL_CLAMP);\n glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_T, GL_CLAMP);\n glTexImage2D(GL_TEXTURE_2D, 0, GL_DEPTH_COMPONENT, RES, RES, 0, GL_DEPTH_COMPONENT, GL_UNSIGNED_BYTE, NULL);\n\n\nEnabled the GL_DEPTH_TEST, then after displaying the objects:\n\nglCopyTexSubImage2D(GL_TEXTURE_2D, 0, 0, 0, 0, 0, RES, RES);\n\n\nthen in the second shader:\n\nfloat depth = tex2D(shadow_array, depthcoord);\n// depthcoord is the actual point's coordinate's in the light's coordinate system\n// epsilon is a very small number\nif (this_depth < depth + epsilon) {\n color = float3(depth, depth, depth);\n}\n\n\nAnd all I'm getting is an all black screen. I tried various things, and I've come to that conclusion, that it seems like my \n\nuniform sample2D shadow_array\n\n\nis containing only 0 values. Because if I change depth's value for example to 0.2, then it's working, so I think the problem is either with the reading from the z-buffer, or reading the shadow map's texture. So how can I save the z-buffer's content to a texture in opengl?"

"How to distinguish long and double-values when deserializing with moshi?",
"My goal is to synchronize abitrary rows of data by using the JSON-Format.\nAs I do not know the exact scheme for the rows (it is a general sync method), my datamodel apparently has to rely on \"Object\". So in Java I will have an array of Map<String,Object> to be synchronized with the server.\n\nTranslating such a row into JSON would give something like\n\n{{\"string\":\"stringvalue\"},{\"double1\":1234.567},{\"double2\":1234.0},{\"long\":1234}}\n\n\nso far, so good - no problem with moshi - everything works as expected.\n\nNow the Problem: When I try to deserialize that JSON with moshi, I get back a double-value for the \"long\" member. Moshi converts all numbers to Doubles. But unfortunately not all numbers can be safely converted to doubles. Very big integers (aka longs) have a problem with the limited precision of doubles. And rounding-effects also might exist.\n\nI opened an issue with moshi, but unfortunately that was closed. Maybe I wasn't clear enough. (Issue 192)\n\nJSON has no concept of integer - only numbers and Strings. But the subtle detail from \"double2\" from the example above might lead to a solution for my problem:\nIf a number does not contain a decimal-point, it is an integer and should be converted to a long.\n\nAs longs can not be losslessly converted to doubles, I need a method to intercept the parser before the value is converted to double. But how to do that?\n\nMoshi has this handy concept of JsonAdapters - but unfortunately I currently do not see how I can use them in this case:\nThe input-type of such an JsonAdapter would have to be Object because I can not cast a generated double to long. So I have to intercept the parser before he converts any value.\nBut how to return more than one type from there? (I would have to return String, Double or Long from there - or if I can limit the inputs to only numbers I would at least have to return Longs or Doubles.)\n\n(My backend is written in PHP and automatically produces the desired output: Integers are written without a decimal-point.)"
