• Reference string as object

  - by xintron

  I've got the following function that manipulates an element according to the data being sent (an object). function manipulateElem (elem, data) { for (var key in data) { elem[key] = data[key]; }; } manipulateElem(document.getElementById('test'), {'href': '/home/', 'style.color': '#000000'}); As you can imagine, the later (style.color) doesn't work. How would one solve this the best way?

• PHP MySQL query string

  - by user1174762

  I am newer to PHP and MySQL and I am having trouble understanding join. I think, for me, the problem lies with actually understanding the logic of the query. What I am trying to do Is select all of the status updates from a table named "post", but only ones from users I am "following", and then display them In order by date. So, I have two databases which are set up like so: posts |post_id|user_id|post_body|date_upload| | 1 | 4 | hey. | 01/2/2012 | follows |relation_id|user_id|followee_id| | 1 | 4 | 2 | Could someone please explain how I should syntactically and Logically set this up? Thank you!

• Add periods in a string [closed]

  - by Garling Beard

  I'm unable to determine why I don't get my expected output, given this code: int periods = (location.Length / 2) - 1; for (int index = 2, i = 0; i < periods; index += 3, ++i ) { location = location.Insert(index, "."); } And a location of "C5032AC", I expect that location will equal "C.50.32.A.C" after my loop terminates; it is instead "C5.03.2AC". Can anyone explain what I'm missing here?

• Monitoring Html Element CSS Changes in JavaScript

  - by Rick Strahl

  [ updated Feb 15, 2011: Added event unbinding to avoid unintended recursion ] Here's a scenario I've run into on a few occasions: I need to be able to monitor certain CSS properties on an HTML element and know when that CSS element changes. For example, I have a some HTML element behavior plugins like a drop shadow that attaches to any HTML element, but I then need to be able to automatically keep the shadow in sync with the window if the  element dragged around the window or moved via code. Unfortunately there's no move event for HTML elements so you can't tell when it's location changes. So I've been looking around for some way to keep track of the element and a specific CSS property, but no luck. I suspect there's nothing native to do this so the only way I could think of is to use a timer and poll rather frequently for the property. I ended up with a generic jQuery plugin that looks like this: (function($){ $.fn.watch = function (props, func, interval, id) { /// <summary> /// Allows you to monitor changes in a specific /// CSS property of an element by polling the value. /// when the value changes a function is called. /// The function called is called in the context /// of the selected element (ie. this) /// </summary> /// <param name="prop" type="String">CSS Properties to watch sep. by commas</param> /// <param name="func" type="Function"> /// Function called when the value has changed. /// </param> /// <param name="interval" type="Number"> /// Optional interval for browsers that don't support DOMAttrModified or propertychange events. /// Determines the interval used for setInterval calls. /// </param> /// <param name="id" type="String">A unique ID that identifies this watch instance on this element</param> /// <returns type="jQuery" /> if (!interval) interval = 200; if (!id) id = "_watcher"; return this.each(function () { var _t = this; var el$ = $(this); var fnc = function () { __watcher.call(_t, id) }; var itId = null; var data = { id: id, props: props.split(","), func: func, vals: [props.split(",").length], fnc: fnc, origProps: props, interval: interval }; $.each(data.props, function (i) { data.vals[i] = el$.css(data.props[i]); }); el$.data(id, data); hookChange(el$, id, data.fnc); }); function hookChange(el$, id, fnc) { el$.each(function () { var el = $(this); if (typeof (el.get(0).onpropertychange) == "object") el.bind("propertychange." + id, fnc); else if ($.browser.mozilla) el.bind("DOMAttrModified." + id, fnc); else itId = setInterval(fnc, interval); }); } function __watcher(id) { var el$ = $(this); var w = el$.data(id); if (!w) return; var _t = this; if (!w.func) return; // must unbind or else unwanted recursion may occur el$.unwatch(id); var changed = false; var i = 0; for (i; i < w.props.length; i++) { var newVal = el$.css(w.props[i]); if (w.vals[i] != newVal) { w.vals[i] = newVal; changed = true; break; } } if (changed) w.func.call(_t, w, i); // rebind event hookChange(el$, id, w.fnc); } } $.fn.unwatch = function (id) { this.each(function () { var el = $(this); var fnc = el.data(id).fnc; try { if (typeof (this.onpropertychange) == "object") el.unbind("propertychange." + id, fnc); else if ($.browser.mozilla) el.unbind("DOMAttrModified." + id, fnc); else clearInterval(id); } // ignore if element was already unbound catch (e) { } }); return this; } })(jQuery); With this I can now monitor movement by monitoring say the top CSS property of the element. The following code creates a box and uses the draggable (jquery.ui) plugin and a couple of custom plugins that center and create a shadow. Here's how I can set this up with the watcher: $("#box") .draggable() .centerInClient() .shadow() .watch("top", function() { $(this).shadow(); },70,"_shadow"); ... $("#box") .unwatch("_shadow") .shadow("remove"); This code basically sets up the window to be draggable and initially centered and then a shadow is added. The .watch() call then assigns a CSS property to monitor (top in this case) and a function to call in response. The component now sets up a setInterval call and keeps on pinging this property every time. When the top value changes the supplied function is called. While this works and I can now drag my window around with the shadow following suit it's not perfect by a long shot. The shadow move is delayed and so drags behind the window, but using a higher timer value is not appropriate either as the UI starts getting jumpy if the timer's set with too small of an increment. This sort of monitor can be useful for other things as well where operations are maybe not quite as time critical as a UI operation taking place. Can anybody see a better a better way of capturing movement of an element on the page?© Rick Strahl, West Wind Technologies, 2005-2011Posted in ASP.NET  JavaScript  jQuery

• I have UFW block messages from local network machines, how can I analyse if they are malicious?

  - by Trygve

  I'm getting a lot of messages in my UFW log, and I'm trying to figure out if these are malicious or just normal. A UDP broadcast is coming from a windows laptop x.x.x.191, and some from our synology disks x.x.x.{6,8,10,11}. I have not figured out which macine 114 is yet. I would appreciate some advice in how to read the log, and get the most I can out of these calls.

• How to achieve selection of a tile from a tile sheet based on an ID?

  - by Bugster

  Let's say I have a tile sheet that contains 8 sprites per sheet. Each sprite is a tile of 30x30. I wrote my own custom map parser/map loader however I'm having trouble extracting a certain tile sprite from the file. I'll describe my problem better in order for everyone to understand. I wrote an enum of materials, each material has a value according to it's location relative to the tile sheet. For example void is 1, grass is 2, rock is 3, etc. So in my tile sheet they are represented as such: +---+---+---+---+---+ | 1 | 2 | 3 | 4 | 5 | +---+---+---+---+---+ Which is equivalent to: +------+-------+-------+ | void | grass | stone | +------+-------+-------+ Basically when rendering, I created a tile class, each tile has 2 coordinates: X and Y (They are calculated automatically) and a material which can be represented either as a number, either as a value (ID). When rendering, I have a vector of sprites which are all taken from 1 file called tilesheet.png, however each of them must only draw a certain portion of the tile sheet, for example say I have something like this: tile coordinateBounds(topLeftX, topLeftY, tileWidth, tileHeight); During the initialization of the map I calculate an array of tiles, and I give each of them their position, their materials based on the values in a map file and a few other variables such as collision. I need to apply the coordinateBounds to each of them according to their material value. For example if the material is grass it should only take the grass sprite from the tilesheet. I must also mention I'm using SFML, and there are no borders or spacing between the tiles.

• Asynchrony in C# 5: Dataflow Async Logger Sample

  - by javarg

  Check out this (very simple) code examples for TPL Dataflow. Suppose you are developing an Async Logger to register application events to different sinks or log writers. The logger architecture would be as follow: Note how blocks can be composed to achieved desired behavior. The BufferBlock<T> is the pool of log entries to be process whereas linked ActionBlock<TInput> represent the log writers or sinks. The previous composition would allows only one ActionBlock to consume entries at a time. Implementation code would be something similar to (add reference to System.Threading.Tasks.Dataflow.dll in %User Documents%\Microsoft Visual Studio Async CTP\Documentation): TPL Dataflow Logger var bufferBlock = new BufferBlock<Tuple<LogLevel, string>>(); ActionBlock<Tuple<LogLevel, string>> infoLogger =     new ActionBlock<Tuple<LogLevel, string>>(         e => Console.WriteLine("Info: {0}", e.Item2)); ActionBlock<Tuple<LogLevel, string>> errorLogger =     new ActionBlock<Tuple<LogLevel, string>>(         e => Console.WriteLine("Error: {0}", e.Item2)); bufferBlock.LinkTo(infoLogger, e => (e.Item1 & LogLevel.Info) != LogLevel.None); bufferBlock.LinkTo(errorLogger, e => (e.Item1 & LogLevel.Error) != LogLevel.None); bufferBlock.Post(new Tuple<LogLevel, string>(LogLevel.Info, "info message")); bufferBlock.Post(new Tuple<LogLevel, string>(LogLevel.Error, "error message")); Note the filter applied to each link (in this case, the Logging Level selects the writer used). We can specify message filters using Predicate functions on each link. Now, the previous sample is useless for a Logger since Logging Level is not exclusive (thus, several writers could be used to process a single message). Let´s use a Broadcast<T> buffer instead of a BufferBlock<T>. Broadcast Logger var bufferBlock = new BroadcastBlock<Tuple<LogLevel, string>>(     e => new Tuple<LogLevel, string>(e.Item1, e.Item2)); ActionBlock<Tuple<LogLevel, string>> infoLogger =     new ActionBlock<Tuple<LogLevel, string>>(         e => Console.WriteLine("Info: {0}", e.Item2)); ActionBlock<Tuple<LogLevel, string>> errorLogger =     new ActionBlock<Tuple<LogLevel, string>>(         e => Console.WriteLine("Error: {0}", e.Item2)); ActionBlock<Tuple<LogLevel, string>> allLogger =     new ActionBlock<Tuple<LogLevel, string>>(     e => Console.WriteLine("All: {0}", e.Item2)); bufferBlock.LinkTo(infoLogger, e => (e.Item1 & LogLevel.Info) != LogLevel.None); bufferBlock.LinkTo(errorLogger, e => (e.Item1 & LogLevel.Error) != LogLevel.None); bufferBlock.LinkTo(allLogger, e => (e.Item1 & LogLevel.All) != LogLevel.None); bufferBlock.Post(new Tuple<LogLevel, string>(LogLevel.Info, "info message")); bufferBlock.Post(new Tuple<LogLevel, string>(LogLevel.Error, "error message")); As this block copies the message to all its outputs, we need to define the copy function in the block constructor. In this case we create a new Tuple, but you can always use the Identity function if passing the same reference to every output. Try both scenarios and compare the results.

• JSF 2.0 Problem

  - by Sarang

  I am doing a project where I am using JSF 2.0 & Primefaces UI Components. There is a tab view component with tabs, "Day","Week" & "Month". In all tab, I have to display Bar Charts in each. For the same, I am fetching three list using the following three method. In the following code, UpdateCountHelper is fetching the data from database. So, UpdateCountHelper is taking some time for fetching data. This is code for fetching lists : public List<UpdateCount> getDayUpdateCounts() { if (projectFlag == true) { if (displayFlag == 1) { dayUpdateCounts = UpdateCountHelper.getProjectUpdates(1); } else { dayUpdateCounts = UpdateCountHelper.getProjectUpdates(name, 1); } } else { dayUpdateCounts = UpdateCountHelper.getResourceUpdates(userName, 1); } return dayUpdateCounts; } public List<UpdateCount> getMonthUpdateCounts() { if (projectFlag == true) { if (displayFlag == 1) { monthUpdateCounts = UpdateCountHelper.getProjectUpdates(30); } else { monthUpdateCounts = UpdateCountHelper.getProjectUpdates(name, 30); } } else { monthUpdateCounts = UpdateCountHelper.getResourceUpdates(userName, 30); } return monthUpdateCounts; } public List<UpdateCount> getWeekUpdateCounts() { if (projectFlag == true) { if (displayFlag == 1) { weekUpdateCounts = UpdateCountHelper.getProjectUpdates(7); } else { weekUpdateCounts = UpdateCountHelper.getProjectUpdates(name, 7); } } else { weekUpdateCounts = UpdateCountHelper.getResourceUpdates(userName, 7); } return weekUpdateCounts; } This is code for UI of Bar Chart : <p:panel id="Chart"> <p:tabView dynamic="false" cache="false"> <p:tab title="Day"> <p:panel id="chartDayPanel"> <center> <h:outputText id="projectWiseDayText" rendered="#{systemUtilizationServiceBean.projectFlag}" value="Project Wise Day Update"/> <p:columnChart id="projectWiseDayUpdateChart" rendered="#{systemUtilizationServiceBean.projectFlag}" value="#{systemUtilizationServiceBean.dayUpdateCounts}" var="dayWiseUpdate" xfield="#{dayWiseUpdate.name}" height="200px" width="640px"> <p:chartSeries label="Project Wise Current Day Update" value="#{dayWiseUpdate.noUpdates}"/> </p:columnChart> <h:outputText id="resourceWiseDayText" rendered="#{systemUtilizationServiceBean.resourceFlag}" value="Resource Wise Day Update"/> <p:columnChart id="resourceWiseDayUpdateChart" rendered="#{systemUtilizationServiceBean.resourceFlag}" value="#{systemUtilizationServiceBean.dayUpdateCounts}" var="dayWiseResourceUpdate" xfield="#{dayWiseResourceUpdate.name}" height="200px" width="640px"> <p:chartSeries label="Resource Wise Current Day Update" value="#{dayWiseResourceUpdate.noUpdates}"/> </p:columnChart> </center> </p:panel> </p:tab> <p:tab title="Week"> <p:panel id="chartWeekPanel"> <center> <h:outputText id="projectWiseWeekText" rendered="#{systemUtilizationServiceBean.projectFlag}" value="Project Wise Week Update"/> <p:columnChart id="projectWiseWeekUpdateChart" rendered="#{systemUtilizationServiceBean.projectFlag}" value="#{systemUtilizationServiceBean.weekUpdateCounts}" var="weekWiseUpdate" xfield="#{weekWiseUpdate.name}" height="200px" width="640px"> <p:chartSeries label="Project Wise Current Week Update" value="#{weekWiseUpdate.noUpdates}"/> </p:columnChart> <h:outputText id="resourceWiseWeekText" rendered="#{systemUtilizationServiceBean.resourceFlag}" value="Resource Wise Week Update"/> <p:columnChart id="resourceWiseWeekUpdateChart" rendered="#{systemUtilizationServiceBean.resourceFlag}" value="#{systemUtilizationServiceBean.weekUpdateCounts}" var="weekWiseResourceUpdate" xfield="#{weekWiseResourceUpdate.name}" height="200px" width="640px"> <p:chartSeries label="Resource Wise Current Week Update" value="#{weekWiseResourceUpdate.noUpdates}"/> </p:columnChart> </center> </p:panel> </p:tab> <p:tab title="Month"> <p:panel id="chartMonthPanel"> <center> <h:outputText id="projectWiseMonthText" rendered="#{systemUtilizationServiceBean.projectFlag}" value="Project Wise Month Update"/> <p:columnChart id="projectWiseMonthUpdateChart" rendered="#{systemUtilizationServiceBean.projectFlag}" value="#{systemUtilizationServiceBean.monthUpdateCounts}" var="monthWiseUpdate" xfield="#{monthWiseUpdate.name}" height="200px" width="640px"> <p:chartSeries label="Project Wise Current Month Update" value="#{monthWiseUpdate.noUpdates}"/> </p:columnChart> <h:outputText id="resourceWiseMonthText" rendered="#{systemUtilizationServiceBean.resourceFlag}" value="Resource Wise Month Update"/> <p:columnChart id="resourceWiseMonthUpdateChart" rendered="#{systemUtilizationServiceBean.resourceFlag}" value="#{systemUtilizationServiceBean.monthUpdateCounts}" var="monthWiseResourceUpdate" xfield="#{monthWiseResourceUpdate.name}" height="200px" width="640px"> <p:chartSeries label="Resource Wise Current Month Update" value="#{monthWiseResourceUpdate.noUpdates}"/> </p:columnChart> </center> </p:panel> </p:tab> </p:tabView> </p:panel> Now, I have to display same data in other tabview with same tabs as mentioned above & only thing is now I have to display in Pie Chart. Now in pie chart, I am using the same lists. So, it will again fetch the data from database & waste time. To solve that problem I have created other three lists & have given only reference of those previous lists. So, now no database fetching occur. The Code for applying the reference is : public List<UpdateCount> getPieDayUpdateCounts() { pieDayUpdateCounts = dayUpdateCounts; return pieDayUpdateCounts; } public List<UpdateCount> getPieMonthUpdateCounts() { pieMonthUpdateCounts = monthUpdateCounts; return pieMonthUpdateCounts; } public List<UpdateCount> getPieWeekUpdateCounts() { pieWeekUpdateCounts = weekUpdateCounts; return pieWeekUpdateCounts; } But, over here the problem occurring is that only chart of which the tab is enable is displayed but the other remaining 2 tabs are not showing any chart. The code for UI is : <p:tabView dynamic="false" cache="false"> <p:tab title="Day"> <center> <p:panel id="pieChartDayPanel"> <h:outputText id="projectWiseDayPieChartText" rendered="#{systemUtilizationServiceBean.projectFlag}" value="Project Wise Day Update"/> <p:pieChart id="projectWiseDayUpdatePieChart" rendered="#{systemUtilizationServiceBean.projectFlag}" value="#{systemUtilizationServiceBean.dayUpdateCounts}" var="dayWisePieUpdate" categoryField="#{dayWisePieUpdate.name}" dataField="#{dayWisePieUpdate.noUpdates}" height="200" width="200"/> <h:outputText id="resourceWiseDayPieChartText" rendered="#{systemUtilizationServiceBean.resourceFlag}" value="Resource Wise Day Update"/> <p:pieChart id="resourceWiseDayUpdatePieChart" rendered="#{systemUtilizationServiceBean.resourceFlag}" value="#{systemUtilizationServiceBean.dayUpdateCounts}" var="dayWiseResourcePieUpdate" categoryField="#{dayWiseResourcePieUpdate.name}" dataField="#{dayWiseResourcePieUpdate.noUpdates}" height="200" width="200"/> </p:panel> </center> </p:tab> <p:tab title="Week"> <center> <p:panel id="pieChartWeekPanel"> <h:outputText id="projectWiseWeekPieChartText" rendered="#{systemUtilizationServiceBean.projectFlag}" value="Project Wise Week Update"/> <p:pieChart id="projectWiseWeekUpdatePieChart" rendered="#{systemUtilizationServiceBean.projectFlag}" value="#{systemUtilizationServiceBean.weekUpdateCounts}" var="weekWisePieUpdate" categoryField="#{weekWisePieUpdate.name}" dataField="#{weekWisePieUpdate.noUpdates}" height="200" width="200"/> <h:outputText id="resourceWiseWeekPieChartText" rendered="#{systemUtilizationServiceBean.resourceFlag}" value="Resource Wise Week Update"/> <p:pieChart id="resourceWiseWeekUpdatePieChart" rendered="#{systemUtilizationServiceBean.resourceFlag}" value="#{systemUtilizationServiceBean.weekUpdateCounts}" var="weekWiseResourcePieUpdate" categoryField="#{weekWiseResourcePieUpdate.name}" dataField="#{weekWiseResourcePieUpdate.noUpdates}" height="200" width="200"/> </p:panel> </center> </p:tab> <p:tab title="Month"> <center> <p:panel id="pieChartMonthPanel"> <h:outputText id="projectWiseMonthPieChartText" rendered="#{systemUtilizationServiceBean.projectFlag}" value="Project Wise Month Update"/> <p:pieChart id="projectWiseMonthUpdatePieChart" rendered="#{systemUtilizationServiceBean.projectFlag}" value="#{systemUtilizationServiceBean.monthUpdateCounts}" var="monthWisePieUpdate" categoryField="#{monthWisePieUpdate.name}" dataField="#{monthWisePieUpdate.noUpdates}" height="200" width="200"/> <h:outputText id="resourceWiseMonthPieChartText" rendered="#{systemUtilizationServiceBean.resourceFlag}" value="Resource Wise Month Update"/> <p:pieChart id="resourceWiseMonthUpdatePieChart" rendered="#{systemUtilizationServiceBean.resourceFlag}" value="#{systemUtilizationServiceBean.monthUpdateCounts}" var="monthWiseResourcePieUpdate" categoryField="#{monthWiseResourcePieUpdate.name}" dataField="#{monthWiseResourcePieUpdate.noUpdates}" height="200" width="200"/> </p:panel> </center> </p:tab> </p:tabView> What should be the reason behind this ?

• How can I "bulk paste" a clipboard string of multi-line text into a readable ordered list?

  - by gunshor

  How can I "bulk paste" a clipboard string of multi-line text into a readable ordered list? I'm trying to demonstrate how to turn any string of multi-line text into an ordered list. The script (preferably JS) needs to respect: - carriage returns at the end of a line, to mean "that line ends here" - indentations at the beginning of a line, to mean "this is part of the item above it" - dashes at the beginning of a line, to mean "this is a task, and the line above it is its project"

• How do I find the highest level TR that contains a specific ID nested in a table

  - by Mykroft

  I have some HTML that looks like this (NOTE: I know this code isn't great but I didn't design it originally and some of it is auto generated): <table id="tab1"> <tr> <td><span>Some text</span></td> <td><span>more text</span></td> <td><input type="text" id="inp1" onclick="DoSomething(this);" /></td> </tr> <tr> <td><span>Some text</span></td> <td><span>more text</span></td> <td><table id="tab2"> <tr><td><input type="radio" id="inp2" onclick="DoSomething(this);" /><span>item</span></td></tr> </table></td> </tr> </table> All of that is embedded in a table which is also embedded in a table and so on. In the DoSomething(this) function I want to retrieve the TR underneath the table tab1. I'm having trouble figuring out the jquery necessary for this. Currently I'm doing something like this: function DoSomething(control) { var parentTab = '<%=tab1.ClientID %>'; var tr = $('#' + parentTab + ' > tbody > tr').has('#' + $(control).attr('id')).get(0); } This seems really messy but works. Is there a cleaner way to do this? If it helps the input inside the table will always be a radio button and a radio button will never appear outside of a sub table. Ideally I'd like to do this without having to know the id of tab1 but that seems impossible.

• How to save/retrieve words to/from SQlite database?

  - by user998032

  Sorry if I repeat my question but I have still had no clues of what to do and how to deal with the question. My app is a dictionary. I assume that users will need to add words that they want to memorise to a Favourite list. Thus, I created a Favorite button that works on two phases: short-click to save the currently-view word into the Favourite list; and long-click to view the Favourite list so that users can click on any words to look them up again. I go for using a SQlite database to store the favourite words but I wonder how I can do this task. Specifically, my questions are: Should I use the current dictionary SQLite database or create a new SQLite database to favorite words? In each case, what codes do I have to write to cope with the mentioned task? Could anyone there kindly help? Here is the dictionary code: package mydict.app; import java.util.ArrayList; import android.database.Cursor; import android.database.sqlite.SQLiteDatabase; import android.database.sqlite.SQLiteException; import android.util.Log; public class DictionaryEngine { static final private String SQL_TAG = "[MyAppName - DictionaryEngine]"; private SQLiteDatabase mDB = null; private String mDBName; private String mDBPath; //private String mDBExtension; public ArrayList<String> lstCurrentWord = null; public ArrayList<String> lstCurrentContent = null; //public ArrayAdapter<String> adapter = null; public DictionaryEngine() { lstCurrentContent = new ArrayList<String>(); lstCurrentWord = new ArrayList<String>(); } public DictionaryEngine(String basePath, String dbName, String dbExtension) { //mDBExtension = getResources().getString(R.string.dbExtension); //mDBExtension = dbExtension; lstCurrentContent = new ArrayList<String>(); lstCurrentWord = new ArrayList<String>(); this.setDatabaseFile(basePath, dbName, dbExtension); } public boolean setDatabaseFile(String basePath, String dbName, String dbExtension) { if (mDB != null) { if (mDB.isOpen() == true) // Database is already opened { if (basePath.equals(mDBPath) && dbName.equals(mDBName)) // the opened database has the same name and path -> do nothing { Log.i(SQL_TAG, "Database is already opened!"); return true; } else { mDB.close(); } } } String fullDbPath=""; try { fullDbPath = basePath + dbName + "/" + dbName + dbExtension; mDB = SQLiteDatabase.openDatabase(fullDbPath, null, SQLiteDatabase.OPEN_READWRITE|SQLiteDatabase.NO_LOCALIZED_COLLATORS); } catch (SQLiteException ex) { ex.printStackTrace(); Log.i(SQL_TAG, "There is no valid dictionary database " + dbName +" at path " + basePath); return false; } if (mDB == null) { return false; } this.mDBName = dbName; this.mDBPath = basePath; Log.i(SQL_TAG,"Database " + dbName + " is opened!"); return true; } public void getWordList(String word) { String query; // encode input String wordEncode = Utility.encodeContent(word); if (word.equals("") || word == null) { query = "SELECT id,word FROM " + mDBName + " LIMIT 0,15" ; } else { query = "SELECT id,word FROM " + mDBName + " WHERE word >= '"+wordEncode+"' LIMIT 0,15"; } //Log.i(SQL_TAG, "query = " + query); Cursor result = mDB.rawQuery(query,null); int indexWordColumn = result.getColumnIndex("Word"); int indexContentColumn = result.getColumnIndex("Content"); if (result != null) { int countRow=result.getCount(); Log.i(SQL_TAG, "countRow = " + countRow); lstCurrentWord.clear(); lstCurrentContent.clear(); if (countRow >= 1) { result.moveToFirst(); String strWord = Utility.decodeContent(result.getString(indexWordColumn)); String strContent = Utility.decodeContent(result.getString(indexContentColumn)); lstCurrentWord.add(0,strWord); lstCurrentContent.add(0,strContent); int i = 0; while (result.moveToNext()) { strWord = Utility.decodeContent(result.getString(indexWordColumn)); strContent = Utility.decodeContent(result.getString(indexContentColumn)); lstCurrentWord.add(i,strWord); lstCurrentContent.add(i,strContent); i++; } } result.close(); } } public Cursor getCursorWordList(String word) { String query; // encode input String wordEncode = Utility.encodeContent(word); if (word.equals("") || word == null) { query = "SELECT id,word FROM " + mDBName + " LIMIT 0,15" ; } else { query = "SELECT id,content,word FROM " + mDBName + " WHERE word >= '"+wordEncode+"' LIMIT 0,15"; } //Log.i(SQL_TAG, "query = " + query); Cursor result = mDB.rawQuery(query,null); return result; } public Cursor getCursorContentFromId(int wordId) { String query; // encode input if (wordId <= 0) { return null; } else { query = "SELECT id,content,word FROM " + mDBName + " WHERE Id = " + wordId ; } //Log.i(SQL_TAG, "query = " + query); Cursor result = mDB.rawQuery(query,null); return result; } public Cursor getCursorContentFromWord(String word) { String query; // encode input if (word == null || word.equals("")) { return null; } else { query = "SELECT id,content,word FROM " + mDBName + " WHERE word = '" + word + "' LIMIT 0,1"; } //Log.i(SQL_TAG, "query = " + query); Cursor result = mDB.rawQuery(query,null); return result; } public void closeDatabase() { mDB.close(); } public boolean isOpen() { return mDB.isOpen(); } public boolean isReadOnly() { return mDB.isReadOnly(); } } And here is the code below the Favourite button to save to and load the Favourite list: btnAddFavourite = (ImageButton) findViewById(R.id.btnAddFavourite); btnAddFavourite.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { // Add code here to save the favourite, e.g. in the db. Toast toast = Toast.makeText(ContentView.this, R.string.messageWordAddedToFarvourite, Toast.LENGTH_SHORT); toast.show(); } }); btnAddFavourite.setOnLongClickListener(new View.OnLongClickListener() { @Override public boolean onLongClick(View v) { // Open the favourite Activity, which in turn will fetch the saved favourites, to show them. Intent intent = new Intent(getApplicationContext(), FavViewFavourite.class); intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK); getApplicationContext().startActivity(intent); return false; } }); }

• What is Rails way to DRY up the controller pattern of verifying :id is for a valid object (else redirect to error page)

  - by jpwynn

  One of my controllers has close to 100 methods (eg routes) and nearly every one starts out the same code to redirect to an error page if the id param is invalid, followed by a similar check if the user that id doesn't belong in the user's account: def something @foo = Foo.find_by_guid(params[:id]) unless @foo @msg ||= { :title => 'No such page!', :desc => "There is no such page!" } render :action => "error" and return end unless @foo.owner_id == current_user.id @msg ||= { :title => 'Really?', :desc => "There is no such page." } render :action => "error" and return end What is the best way to DRY up that sort of page id and owner id validation, given the code is doing a render ... and return? What I don't want to do at this point is offload it to a blackbox roles and permissions library like CanCan... my goal is simply to have the in-app code to handle this be as clean as possible.

• Is it good practice to keep 2 related tables (using auto_increment PK) to have the same Max of auto_increment ID when table1 got modified?

  - by Tum

  This question is about good design practice in programming. Let see this example, we have 2 interrelated tables: Table1 textID - text 1 - love.. 2 - men... ... Table2 rID - textID 1 - 1 2 - 2 ... Note: In Table1: textID is auto_increment primary key In Table2: rID is auto_increment primary key & textID is foreign key The relationship is that 1 rID will have 1 and only 1 textID but 1 textID can have a few rID. So, when table1 got modification then table2 should be updated accordingly. Ok, here is a fictitious example. You build a very complicated system. When you modify 1 record in table1, you need to keep track of the related record in table2. To keep track, you can do like this: Option 1: When you modify a record in table1, you will try to modify a related record in table 2. This could be quite hard in term of programming expecially for a very very complicated system. Option 2: instead of modifying a related record in table2, you decided to delete old record in table 2 & insert new one. This is easier for you to program. For example, suppose you are using option2, then when you modify record 1,2,3,....,100 in table1, the table2 will look like this: Table2 rID - textID 101 - 1 102 - 2 ... 200 - 100 This means the Max of auto_increment IDs in table1 is still the same (100) but the Max of auto_increment IDs in table2 already reached 200. what if the user modify many times? if they do then the table2 may run out of records? we can use BigInt but that make the app run slower? Note: If you spend time to program to modify records in table2 when table1 got modified then it will be very hard & thus it will be error prone. But if you just clear the old record & insert new records into table2 then it is much easy to program & thus your program is simpler & less error prone. So, is it good practice to keep 2 related tables (using auto_increment PK) to have the same Max of auto_increment ID when table1 got modified?

• Linux, some packets are not being NAT

  - by user70932

  Hi, I'm trying to NAT HTTP traffic, I'm new to this and facing some issues. What i'm trying to do is NAT client HTTP requests to a webserver. CLIENT - NAT BOX - WEBSERVER When the client open the IP of the NAT BOX, the request should be pass to the web server. But I'm getting "HTTP request sent, awaiting response..." and then wait serveral minutes before the request is done. Looking at the tcpdump output, it looks like the first Syn packet on (10:48:54) is being NAT but not the second, third, fourth... ACK or PSH packets, and wait until (10:52:04) it starts NAT again on the ACK packet. The iptables command I'm using is: iptables -t nat -A PREROUTING -p tcp -i eth0 --dport 80 \ -j DNAT --to-destination WEBSERVER I'm wondering what could have caused this behavior?

• org-sort multi: date/time (?d ?t) | priority (?p) | title (?a)

  - by lawlist

  Is anyone aware of an org-sort function / modification that can refile / organize a group of TODO so that it sorts them by three (3) criteria: first sort by due date, second sort by priority, and third sort by by title of the task? EDIT: I believe that org-sort by deadline (?d) has a bug that cannot properly handle undated tasks. I am working on a workaround (i.e., moving the undated todo to a different heading before the deadline (?d) sort occurs), but perhaps the best thing to do would be to try and fix the original sorting function. Development of the workaround can be found in this thread (i.e., moving the undated tasks to a different heading in one fell swoop): How to automate org-refile for multiple todo EDIT: Apparently, the following code (ancient history) that I found on the internet was eventually modified and included as a part of org-sort-entries. Unfortunately, undated todo are not properly sorted when sorting by deadline -- i.e., they are mixed in with the dated todo. ;; multiple sort (defun org-sort-multi (&rest sort-types) "Multiple sorts on a certain level of an outline tree, or plain list items. SORT-TYPES is a list where each entry is either a character or a cons pair (BOOL . CHAR), where BOOL is whether or not to sort case-sensitively, and CHAR is one of the characters defined in `org-sort-entries-or-items'. Entries are applied in back to front order. Example: To sort first by TODO status, then by priority, then by date, then alphabetically (case-sensitive) use the following call: (org-sort-multi '(?d ?p ?t (t . ?a)))" (interactive) (dolist (x (nreverse sort-types)) (when (char-valid-p x) (setq x (cons nil x))) (condition-case nil (org-sort-entries (car x) (cdr x)) (error nil)))) ;; sort current level (defun lawlist-sort (&rest sort-types) "Sort the current org level.

• MegaCli newly created disk doesn't appear under /dev/sdX

  - by Henry-Nicolas Tourneur

  After having successfully added 2 new disks in a new RAID virtual drive (background initialization done), I would have exepected it to appear under /dev/sdh but it's not there (so, unusable). The system is running a CentOS 5.2 64 bits, HAL and udev daemons are running, not records of any sdh apparition under the messsage log file or in dmesg, only MegaCli do see that virtual drive. Any idea ? Some data: [root@server ~]# ./MegaCli -LDInfo -LALL -a0 Adapter 0 -- Virtual Drive Information: Virtual Disk: 0 (target id: 0) Name: RAID Level: Primary-1, Secondary-0, RAID Level Qualifier-0 Size:139392MB State: Optimal Stripe Size: 64kB Number Of Drives:2 Span Depth:1 Default Cache Policy: WriteBack, ReadAheadNone, Direct, No Write Cache if Bad BBU Current Cache Policy: WriteBack, ReadAheadNone, Direct, No Write Cache if Bad BBU Access Policy: Read/Write Disk Cache Policy: Disk's Default Virtual Disk: 1 (target id: 1) Name: RAID Level: Primary-1, Secondary-0, RAID Level Qualifier-0 Size:285568MB State: Optimal Stripe Size: 64kB Number Of Drives:2 Span Depth:1 Default Cache Policy: WriteBack, ReadAheadNone, Direct, No Write Cache if Bad BBU Current Cache Policy: WriteBack, ReadAheadNone, Direct, No Write Cache if Bad BBU Access Policy: Read/Write Disk Cache Policy: Disk's Default [root@server ~]# ls -l /dev/disk/by-id/scsi-360* lrwxrwxrwx 1 root root 9 Nov 17 2010 /dev/disk/by-id/scsi-36001ec90f82fe100108ca0a704098d09 -> ../../sda lrwxrwxrwx 1 root root 10 Nov 17 2010 /dev/disk/by-id/scsi-36001ec90f82fe100108ca0a704098d09-part1 -> ../../sda1 lrwxrwxrwx 1 root root 10 Nov 17 2010 /dev/disk/by-id/scsi-36001ec90f82fe100108ca0a704098d09-part2 -> ../../sda2 lrwxrwxrwx 1 root root 9 Nov 17 2010 /dev/disk/by-id/scsi-36090a028e0fe07e78f94940c0000a0ee -> ../../sdf lrwxrwxrwx 1 root root 10 Nov 17 2010 /dev/disk/by-id/scsi-36090a028e0fe07e78f94940c0000a0ee-part1 -> ../../sdf1 lrwxrwxrwx 1 root root 9 Nov 17 2010 /dev/disk/by-id/scsi-36090a028e0fe972a3f91240a0000005f -> ../../sdb lrwxrwxrwx 1 root root 10 Nov 17 2010 /dev/disk/by-id/scsi-36090a028e0fe972a3f91240a0000005f-part1 -> ../../sdb1 lrwxrwxrwx 1 root root 9 Nov 17 2010 /dev/disk/by-id/scsi-36090a028e0fea7e18f94640c000020ec -> ../../sde lrwxrwxrwx 1 root root 10 Nov 17 2010 /dev/disk/by-id/scsi-36090a028e0fea7e18f94640c000020ec-part1 -> ../../sde1 lrwxrwxrwx 1 root root 9 Nov 17 2010 /dev/disk/by-id/scsi-36090a028e0feb7da8f94340c0000203d -> ../../sdd lrwxrwxrwx 1 root root 10 Nov 17 2010 /dev/disk/by-id/scsi-36090a028e0feb7da8f94340c0000203d-part1 -> ../../sdd1 lrwxrwxrwx 1 root root 9 Nov 17 2010 /dev/disk/by-id/scsi-36090a028e0fed7d78f94040c000080b7 -> ../../sdc lrwxrwxrwx 1 root root 10 Nov 17 2010 /dev/disk/by-id/scsi-36090a028e0fed7d78f94040c000080b7-part1 -> ../../sdc1 lrwxrwxrwx 1 root root 9 Nov 17 2010 /dev/disk/by-id/scsi-36090a05830145e58e0b9c479000010a1 -> ../../sdg lrwxrwxrwx 1 root root 10 Nov 17 2010 /dev/disk/by-id/scsi-36090a05830145e58e0b9c479000010a1-part1 -> ../../sdg1

• Using AsyncTask to display data in ListView, but onPostExecute not being called

  - by sumisu

  I made a simple AsyncTask class to display data in ListView with the help of this stackoverflow question. But the AsyncTask onPostExecute is not being called. This is my code: public class Start extends SherlockActivity { // JSON Node names private static final String TAG_ID = "id"; private static final String TAG_NAME = "name"; // category JSONArray JSONArray category = null; private ListView lv; @Override public void onCreate(Bundle savedInstanceState) { setTheme(SampleList.THEME); //Used for theme switching in samples super.onCreate(savedInstanceState); setContentView(R.layout.test); new MyAsyncTask().execute("http://...."); // Launching new screen on Selecting Single ListItem lv.setOnItemClickListener(new OnItemClickListener() { @Override public void onItemClick(AdapterView<?> parent, View view, int position, long id) { // getting values from selected ListItem String name = ((TextView) view.findViewById(R.id.name)).getText().toString(); String cost = ((TextView) view.findViewById(R.id.mail)).getText().toString(); // Starting new intent Intent in = new Intent(getApplicationContext(), SingleMenuItemActivity.class); in.putExtra("categoryname", name); System.out.println(cost); in.putExtra("categoryid", cost); startActivity(in); } }); } public class MyAsyncTask extends AsyncTask<String, Void, ArrayList<HashMap<String, String>> > { // Hashmap for ListView ArrayList<HashMap<String, String>> contactList = new ArrayList<HashMap<String, String>>(); @Override protected ArrayList<HashMap<String, String>> doInBackground(String... params) { // Creating JSON Parser instance JSONParser jParser = new JSONParser(); // getting JSON string from URL category = jParser.getJSONArrayFromUrl(params[0]); try { // looping through All Contacts for(int i = 0; i < category.length(); i++){ JSONObject c = category.getJSONObject(i); // Storing each json item in variable String id = c.getString(TAG_ID); String name = c.getString(TAG_NAME); // creating new HashMap HashMap<String, String> map = new HashMap<String, String>(); // adding each child node to HashMap key => value map.put(TAG_ID, id); map.put(TAG_NAME, name); // adding HashList to ArrayList contactList.add(map); } } catch (JSONException e) { Log.e("log_tag", "Error parsing data "+e.toString()); } return contactList; } @Override protected void onPostExecute(ArrayList<HashMap<String, String>> result) { ListAdapter adapter = new SimpleAdapter(Start.this, result , R.layout.list_item, new String[] { TAG_NAME, TAG_ID }, new int[] { R.id.name, R.id.mail }); // selecting single ListView item lv = (ListView) findViewById(R.id.ListView); lv.setAdapter(adapter); } } } Eclipse: 11-25 11:40:31.896: E/AndroidRuntime(917): java.lang.RuntimeException: Unable to start activity ComponentInfo{de.essentials/de.main.Start}: java.lang.NullPointerException
