"Correct location for ESAPI.properties under web project",
"I added a OWASP ESAPI library to my project. And currently I'm stuck with a problem where to locate ESAPI.properties file. This project later should be deployed on few servers to which I don't have an access. So in my opinion there is no way to customizeorg.owasp.esapi.resources variable and I can't put it under user home directory. So the only place where I can put this file is SystemResource Directory/resourceDirectory but where is it? I have already tried to put these files:\n\n.esapi/ESAPI.properties\nesapi/ESAPI.properties\nESAPI.properties\n\n\nInto these locations:\n\n$CATALINA_HOME/webapps/<MY_PROJECT>/\n$CATALINA_HOME/webapps/<MY_PROJECT>/WEB-INF\n$CATALINA_HOME/webapps/<MY_PROJECT>/WEB-INF/classes\n$CATALINA_HOME/webapps/<MY_PROJECT>/META-INF\n\n\nBut in all of these places I get an error:\nNot found in SystemResource Directory/resourceDirectory: .esapi\\ESAPI.properties\n\nSo where I should locate this file? It's a legacy project(just Eclipse Project without Maven) and it's structure is pretty ugly. There is no such directory like /src/main/resources where in my opinion this ESAPI.properties file should be located. I have created this directory, but where finally this file should be after deployment a WAR archive to Tomcat?"

"Returning text between a starting and ending regular expression",
"I am working on a regular expression to extract some text from files downloaded from a newspaper database. The files are mostly well formatted. However, the full text of each article starts with a well-defined phrase ^Full text:. However, the ending of the full-text is not demarcated. The best that I can figure is that the full text ends with a variety of metadata tags that look like: Subject: , CREDIT:, Credit. \n\nSo, I can certainly get the start of the article. But, I am having a great deal of difficulty finding a way to select the text between the start and the end of the full text. \n\nThis is complicated by two factors. First, obviously the ending string varies, although I feel like I could settle on something like: `^[:alnum:]{5,}: ' and that would capture the ending. But the other complicating factor is that there are similar tags that appear prior to the start of the full text. How do I get R to only return the text between the Full text regex and the ending regex?\n\ntest<-c('Document 1', 'Article title', 'Author: Author Name', 'https://a/url', 'Abstract: none', 'Full text: some article text that I need to capture','the second line of the article that I need to capture', 'Subject: A subject', 'Publication: Publication', 'Location: A country')\n\ntest2<-c('Document 2', 'Article title', 'Author: Author Name', 'https://a/url', 'Abstract: none', 'Full text: some article text that I need to capture','the second line of the article that I need to capture', 'Credit: A subject', 'Publication: Publication', 'Location: A country')\n\nMy current attempt is here:\n\ntest[(grep('Full text:', test)+1):grep('^[:alnum:]{5,}: ', test)]\n\nThank you."

What I infer from this is that sometimes it goes faster and then it slows down and continue going faster."

"angular2 router unexpectedly recreates components when navigating",
"Router instantiates a new component every time navigating to a different component type. This has serious repercussions. Also, this is very different paradigm not only from previous versions of the router, but any routing framework. \n\nHere is an example: A user may be in the middle of filling a long form on a tab1, he needs to lookup or verify some other details in tab2, when he comes back to tab1, everything is wiped out (as the component is re-instantiated). This implies that every time a user makes a change on a part of the UI, the state if the UI should be preserved (in anticipation of his unexpected navigation to another component, which co-exists on the same UI. \n\nOn a complex UI, say with graphics and multiple open tree controls (reflecting a user who is in middle of something), one would have to not only preserve content, but also unnecessarily preserve state of every bit of various widgets or graphics on the component. If the router had an option of reusing the components on the tree, (when navigating to a component of a different type from current component), one doesn't have to preserve the UI state. \n\nThis idea of destroying the component every time (someone navigates to a different type of component) doesn't sound right from a performance point of view as well. the model from heavy backend call, would have to be cached or call repeated. \n\nWhat are your experiences with this routing model?\n\nThis design makes the developer do a lot extra work (to preserve and recreate the work in progress - which we have never even cared about in the past) the and places performance penalty on the application. How do you overcome these challanges?\n\nUI-router another third party routing library (has been around since angular1 days) doesn't mandate/ force the developer by recreating components. Did you adopt it as an alternative? Any recommendations of if UI-Router is a better alternative than Router 3?"

"How do I conditionally uninstall shared object (Merge Module) files in WiX?",
"I have a common merge module as a part Wix installer MySetup1.msi, that should always deliver files and install service, but should only uninstall the merge module files/service when a condition is met. The condition is that common files should be uninstalled only when specific property is passed.\nThe merge module is also part MySetup2.msi.\nI understand this can be done by using same GUIDs across components or using merge modules, but\nMySetup1.msi should not uninstall merge module component, expectional case module can be uninstalled if specific FLAG is passed or else merge module should be uninstalled via MySetup2\nHere little complexity, as we have shared component with common GUID, MSI installer service keep reference for shared object\nIf we skip to uninstall in MySetup1.MSI, I think one ref count will be pending.\nAnd on MySetup2.msi uninstall this file will not deleted as there will be always refcount 1.\nAny hints clue really appreciated,\nI know reference counts kept at registry HKEY_LOCAL_MACHINE\\SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Installer\\UserData\\Component\nbut bit skeptical about manipulating reg entries.\nHere is code snipped where I am merging this module in original installer, but unfortunately did not worked any help really appriciated.\n<Feature Id="MyMergedFeature" Title="My Merged Feature" Level="0" AllowAdvertise="no" Absent="disallow">\n<MergeRef Id='MyModule' />\n <Condition Level="0">\n <![CDATA[REMOVE ~<> "ALL"]]>\n </Condition>\n</Feature>"

"Is it appropriate to raise exceptions in stored procedures that wrap around CRUD operations, when the number of rows affected != 1?",
"This is a pretty specific question, albeit possibly subjective, but I've been using this pattern very frequently while not seeing others use it very often. Am I missing out on something or being too paranoid?\n\nI wrap all my UPDATE,DELETE,INSERT operations in stored procedures, and only give EXECUTE on my package and SELECT on my tables, to my application. For the UPDATE and DELETE procedures I have an IF statement at the end in which I do the following:\n\nIF SQL%ROWCOUNT <> 1 THEN\n RAISE_APPLICATION_ERROR(-20001, 'Invalid number of rows affected: ' || SQL%ROWCOUNT);\nEND IF;\n\n\nOne could also do this check in the application code, as the number of rows affected is usually available after a SQL statement is executed.\n\nSo am I missing something or is this not the safest way to ensure you're updating or deleting exactly what you want to, nothing more, nothing less?"

"Spark: Run through List Asyncronously and perform SparkContext Actions",
"In my application I am running through a list synchronously in order to process all hostnames in a list. \n\nWhile the application works, the problem is I want to now be able to run through that list asynchronously, however I am not entirely sure how to do this with spark since the SparkContext object is not serializable, meaning you can only have a single SparkContext object running at any given time, preventing you from doing multiple spark actions simultaneously. \n\nSo my question is, how do other people approach this problem? Maybe I am not thinking about it in the right way. \n\nPossible Solution: Map List(modelFilteredTopology) to a JavaRDD and then use JavaRDD.foreachAsync(Call MapProcessing with VoidFunction) in order to perform the actions asynchronously. However I may run into some head scratching issues if I do this. And I believe I will still be limited by the SparkContext as it wont execute the actions asynchronously anyways. \n\nSample of my code below:\n\nMainClass.java snippet - Loads some data from a SchemaRDD over to a LIST\n\n List<modelFilteredTopology> filteredList = FILTERED_TOPOLOGY.map(new Function<Row, modelFilteredTopology>() {\n public modelFilteredTopology call(Row row){\n modelFilteredTopology modelF = new modelFilteredTopology();\n\n modelF.setHOSTNAME(row.getString(0));\n modelF.setMODEL(row.getString(1));\n modelF.setCOMMIT_TS(new SimpleDateFormat(\"yyyy-MM-dd\").format(Calendar.getInstance().getTime()));\n\n return modelF;\n }\n }).collect();\n\n for(modelFilteredTopology f : filteredList) {\n MapProcessing2 map = new MapProcessing2(schemaTopology, sc, sqlContext);\n map.runApp(f.getHOSTNAME(),f.getMODEL(),f.getCOMMIT_TS());\n }\n\n\nMapProcessing2.class - This is a small snippet of the code that performs a TON of JAVARDD transformations, I have to make SparkContext static, otherwise it will obviously through a Serialization not allowed error. \n\npublic class MapProcessing2 implements Serializable {\n\nprivate static final Integer HISTORYDATE = 30;\nprivate static JavaSchemaRDD TOPO_EXTRACT;\nprivate static JavaSparkContext SC;\nprivate static JavaSQLContext sqlContext;\nprivate static final String ORACLE_DRIVER = Properties.getString(\"OracleDB_Driver\");\nprivate static final String ORACLE_CONNECTION_URL_PROD = Properties.getString(\"DB_Connection_PROD\");\nprivate static final String ORACLE_USERNAME_PROD = Properties.getString(\"DB_Username_PROD\");\nprivate static final String ORACLE_PASSWORD_PROD = Properties.getString(\"DB_Password_PROD\");\n\npublic MapProcessing2(JavaSchemaRDD TOPO_EXTRACT, JavaSparkContext SC, JavaSQLContext sqlContext) {\n this.TOPO_EXTRACT = TOPO_EXTRACT;\n this.SC = SC;\n this.sqlContext = sqlContext;\n\n}\npublic void runApp(String hostname, String model, String commits) throws Exception{\n if (String.valueOf(hostname).equals(\"null\")) {\n System.out.println(\"No Value Retrieved\");\n } else {\n try {\n //Retrieve Tickets for GWR\n JavaSchemaRDD oltint = getOLTInterfaces(TOPO_EXTRACT, hostname);\n System.out.println(\"Number of OLT's Found for \"+hostname+\": \" + oltint.collect().size());\n if (oltint.collect().size() < 1) {\n System.out.println(\"No OLT's found for: \" + hostname);\n } else {\n System.out.println(\"Processing Router: \" + hostname + \" Model:\" + model);\n\n System.out.println(\"Processing Tickets for: \" + hostname + \" \" + model);\n }\n\n } catch (Exception e) {\n System.out.println(\"Error Processing GWR: \" + hostname + \" \" + model + \" Stacktrace Error: \" + e);\n }\n }\n}"

As a simple example of the problem that I am facing take the following code to generate a 1000 cell x 1000 cell multiplication table.\n\nimport win32com.client\nfrom win32com.client import constants as c\n\nxl = win32com.client.gencache.EnsureDispatch(\"Excel.Application\") \nxl.Visible = True\nWorkbook = xl.Workbooks.Add()\nSheets = Workbook.Sheets\n\ntableSize = 1000\n\nfor i in range(tableSize):\n for j in range(tableSize):\n Sheets(1).Cells(i+1, j+1).Value = i*j\n\n\nFor small values this works. However, for larger values the python program eventually crashes with the error:\n\nTraceback (most recent call last):\n File \".\\Example.py\", line 16, in <module>\n Sheets(1).Cells(i+1, j+1).Value = i*j\n File \"C:\\PYTHON27\\lib\\site-packages\\win32com\\client\\__init__.py\", line 474, in __setattr__\n self._oleobj_.Invoke(*(args + (value,) + defArgs)) pywintypes.com_error: (-2147352567, 'Exception occurred.', (0, None, None, None, 0, -2146777998), None)\n\n\nI've already admitted defeat due to the fact that this is significantly slower than xlwt but I am still curious as to what is happening to cause this error."
