• compressed archive with quick access to individual file

  - by eric.frederich

  I need to come up with a file format for new application I am writing. This file will need to hold a bunch other text files which are mostly text but can be other formats as well. Naturally, a compressed tar file seems to fit the bill. The problem is that I want to be able to retrieve some data from the file very quickly and getting just a particular file from a tar.gz file seems to take longer than it should. I am assumeing that this is because it has to decompress the entire file even though I just want one. When I have just a regular uncompressed tar file I can get that data real quick. Lets say the file I need quickly is called data.dat For example the command... tar -x data.dat -zf myfile.tar.gz ... is what takes a lot longer than I'd like. MP3 files have id3 data and jpeg files have exif data that can be read in quickly without opening the entire file. I would like my data.dat file to be available in a similar way. I was thinking that I could leave it uncompressed and seperate from the rest of the files in myfile.tar.gz I could then create a tar file of data.dat and myfile.tar.gz and then hopefully that data would be able to be retrieved faster because it is at the head of outer tar file and is uncompressed. Does this sound right?... putting a compressed tar inside of a tar file? Basically, my need is to have an archive type of file with quick access to one particular file. Tar does this just fine, but I'd also like to have that data compressed and as soon as I do that, I no longer have quick access. Are there other archive formats that will give me that quick access I need? As a side note, this application will be written in Python. If the solution calls for a re-invention of the wheel with my own binary format I am familiar with C and would have no problem writing the Python module in C. Idealy I'd just use tar, dd, cat, gzip, etc though. Thanks, ~Eric

• PASS Summit for SQL Starters

  - by Davide Mauri

  I’ve received a buch of emails from PASS Summit “First Timers” that are also somehow new to SQL Server (for “somehow” I mean people with less than 6 month experience but with some basic knowledge of SQL Server engine) or are catching up from SQL Server 2000. The common question regards the session one should not miss to have a broad view of the entire SQL Server platform have some insight into some specific areas of SQL Server Given that I’m on (semi-)vacantion and that I have more free time (not true, I have to prepare slides & demos for several conferences, PASS Summit  - Building the Agile Data Warehouse with SQL Server 2012 - and PASS 24H - Agile Data Warehousing with SQL Server 2012 - among them…but let’s pretend it to be true), I’ve decided to make a post to answer to this common questions. Of course this is my personal point of view and given the fact that the number and quality of session that will be delivered at PASS Summit is so high that is very difficoult to make a choice, fell free to jump into the discussion and leave your feedback or – even better – answer with another post. I’m sure it will be very helpful to all the SQL Server beginners out there. I’ve imposed to myself to choose 6 session at maximum for each Track. Why 6? Because it’s the maximum number of session you can follow in one day, and given that all the session will be on the Summit DVD, they are the answer to the following question: “If I have one day to spend in training, which session I should watch?”. Of course a Summit is not like a Course so a lot of very basics concept of well-established technologies won’t be found here. Analysis Services, Integration Services, MDX are not part of the Summit this time (at least for the basic part of them). Enough with that, let’s start with the session list ideal to have a good Overview of all the SQL Server Platform: Geospatial Data Types in SQL Server 2012 Inside Unstructured Data: SQL Server 2012 FileTable and Semantic Search XQuery and XML in SQL Server: Common Problems and Best Practice Solutions Microsoft's Big Play for Big Data Dashboards: When to Choose Which MSBI Tool Microsoft BI End-User Tools 360° for what concern Database Development, I recommend the following sessions Understanding Transaction Isolation Levels What to Look for in Execution Plans Improve Query Performance by Fixing Bad Parameter Sniffing A Window into Your Data: Using SQL Window Functions Practical Uses and Optimization of New T-SQL Features in SQL Server 2012 Taking MERGE Beyond the Basics For Business Intelligence Information Delivery Analyzing SSAS Data with Excel Building Compelling Power View Reports Managed Self-Service BI PowerPivot 101  SharePoint for Business Intelligence The Best Microsoft BI Tools You've Never Heard Of and for Business Intelligence Architecture & Development BI Power Hour Building a Tabular Model Database Enterprise Information Management: Bringing Together SSIS, DQS, and MDS SSIS Design Patterns Storing Columnstore Indexes Hadoop and Its Ecosystem Components in Action Beside the listed sessions, First Timers should also take a look the the page PASS set up for them: http://www.sqlpass.org/summit/2012/Connect/FirstTimers.aspx See you at PASS Summit!

• All hail the Excel Queen

  - by Tim Dexter

  An excellent question this past week from dear ol Blighty; actually from Brian at Nextgen Clearing Ltd in the big smoke (London). Brian was developing an excel template and wanted to be able to reference the data fields multiple times inside the Excel template. Damn good question and I of course has some wacky solutions, from macros and cell referencing in Excel to pre-processing the data with an XSL stylesheet to copy the data multiple times so it could be referenced multiple times. All completely outlandish, enter our Queen of Excel, Shirley from the development team. Shirley is singlehandedly responsible for the Excel templates, I put her through six months of hell a few years back, with a host of Excel template requirements. She was more than up to the challenge and has developed some great features. One of those, is the ability to use the hidden XDO_METADATA sheet to map the data to custom named fields so they can be used multiple times in the template. So simple and very neat! Excel template and regular Excel users will know that you can only use the naming function once ie the names have to be unique across the workbook so you can not reuse a cell/group name. To get around this you can just come up with as many cell names as you want and map them in the XDO_METADATA sheet to the data columns/fields in your XML data set:. For example: XDO_?DEPTNO_SUMMARY?  <?DEPTNO?> XDO_?DNAME_SUMMARY?  <?DNAME?> XDO_GROUP_?G_D_DETAIL? <xsl:for-each-group select=".//G_D" group-by="./DEPTNO"> XDO_?DEPTNO_DETAIL? <?DEPTNO?> As you can see DEPTNO has been referenced twice and mapped to different named values in the left hand column. These values can then be used to name individual cells in the Excel template. You'll also notice a mix of Publisher <? ...?> and native XSL commands. So the world is your oyster on the mapping and the complexity you might need for calculations or string manipulation. Shirley has kindly built out a sample Excel template, data and result here so you can see how it all hangs together. the XDO_METADATA sheet is hidden, just right click on the sheet names and use the Unhide command to show it.

• why do I need the @ for setting variable value

  - by Saad

  I'm a little confused about scope of variables, in ruby I wrote a test program: class Test attr_reader :tester def initialize(data) @tester = data end def getData tester end end puts Test.new(11).getData now this works fine, the attr_reader, but my confusion is that since I've define attr_reader :tester then why can't I go tester = data rather then @tester = data, because when retrieving the data in getData I only have to write tester and not @tester

• JavaOne 2013: (Key) Notes of a conference – State of the Java platform and all the roadmaps by Amis

  - by JuergenKress

  Last week’s JavaOne conference provided insights in the roadmap of the Java platform as well as in the current state of things in the Java community. The close relationship between Oracle and IBM concerning Java, the (continuing) lack of such a relationship with Google, the support from Microsoft for Java applications on its Azure cloud and the vibrant developer community – with over 200 different Java User Groups in many countries of the world. There were no major surprises or stunning announcements. Java EE 7 (release in June) was celebrated, the progress of Java 8 SE explained as well as the progress on Java Embedded and ME. The availability of NetBeans 7.4 RC1 and JDK 8 Early Adopters release as well as the open sourcing of project Avatar probably were the only real news stories. The convergence of JavaFX and Java SE is almost complete; the upcoming alignment of Java SE Embedded and Java ME is the next big consolidation step that will lead to a unified platform where developers can use the same skills, development tools and APIs on EE, SE, SE Embedded and ME development. This means that anything that runs on ME will run on SE (Embedded) and EE – not necessarily the reverse because not all SE APIs are part of the compact profile or the ME environment. However, the trimming down of the SE libraries and the increased capabilities of devices mean that a pretty rich JVM runs on many devices – such as JavaFX 8 on the Raspberry PI. The major theme of the conference was Internet of Things. A world of things that are smart and connected, devices like sensors, cameras and equipment from cars, fridges and television sets to printers, security gates and kiosks that all run Java and are all capable of sending data over local network connections or directly over the internet. The number of devices that has these capabilities is rapidly growing. This means that the number of places where Java programs can help program the behavior of devices is growing too. It also means that the volume of data generated is expanding and that we have to find ways to harvest that data, possibly do a local pre-processing (filter, aggregate) and channel the data to back end systems. Terms typically used are edge devices (small, simple, publishing data), gateways (receiving data from many devices, collecting and consolidating, pre-processing, sending onwards to back end – typically using real time event processing) and enterprise services – receiving the data-turned-information from the gateways to further consolidate, distribute and act upon. A cheap device like the Raspberry PI is a perfect way to get started as a Java developer with what embedded (device) programming means and how interaction with physical input and output takes place. Roadmaps The over all progress on Java is visualized in this overview: Read the full article here.

• Translate Linq Expression to any existing Query structure?

  - by fredlegrain

  I have some kind of "data engine" between multiple "data consumer" processes and multiple "data storage" sources. I'd like to provide Linq capabilities to the "data consumer" and forward the query to the "data storage". The forwarded query should be some structured query (like, let's say, NHibernate Criteria). Is there any existing structured query library that could allow me to "just" translate a Linq Expression to such a structured query?

• CSS Graph- Bars not showing correctly

  - by Olivia

  I'm trying to create a CSS/HTML based graph using this tutorial here. However instead of putting the data directly into the html code I'm importing it from a CSV file using PHP with the following code. <?PHP /* Open CSV file */ $handle = fopen("defects.csv", "r"); $c = 0; /* gets data from csv file */ while (($data = fgetcsv($handle, 1000, ",")) !== FALSE) { /* stores dates as variable $date */ $date[$c] = $data[0]; $c++; /* inserts defect data into html code */ echo "<dd class=\"p" . $data[2] . "\"><span><b>" . $data[2] . "</b></span></dd>"; echo "<dd class=\"sub p" . $data[3] . "\" ><span><b>" . $data[3] . "</b></span></dd>"; } echo "</dl>"; echo "<ul class=\"xAxis\">"; /* X AXIS */ /* inserts date data into html code for x axis */ for ($d=0; $d < $c; $d++) { echo "<li>" . $date[$d] . "</li>"; } ?> The values are being placed correctly on the chart, but the bars aren't appearing. The CSS code I have for the bars is: /* default column styling */ dl#csschart span{ height:50%; background:url(../images/barx.png) repeat-y; } dl#csschart .sub{ margin-left:-33px; } dl#csschart .sub span{ background:url(../images/subBarx.png) repeat-y; } Just in case it helps, I've print screened how the graph should look. You can see it at: http://allured.info/graph/failgraph.png

• Intent filter for browsing XML (specifically rss) in android

  - by Leif Andersen

  I have an activity that I want to run every time the user goes to an xml (specifically rss) page in the browser (at least assuming the user get's it from the list of apps that can support it). I currently already have the current intent filter: <activity android:name=".activities.EpisodesListActivity" android:theme="@android:style/Theme.NoTitleBar"> <intent-filter> <category android:name="android.intent.category.BROWSABLE"></category> <category android:name="android.intent.category.DEFAULT"></category> <action android:name="android.intent.action.VIEW"></action> <data android:scheme="http"></data> </intent-filter> </activity> Now as you can guess, this is an evil intent, as it wants to open whenever a page is requested via http. However, when I ad the line: <data android:mimeType="application/rss+xml"></data> to make it: <activity android:name=".activities.EpisodesListActivity" android:theme="@android:style/Theme.NoTitleBar"> <intent-filter> <category android:name="android.intent.category.BROWSABLE"></category> <category android:name="android.intent.category.DEFAULT"></category> <action android:name="android.intent.action.VIEW"></action> <data android:scheme="http"></data> <data android:mimeType="application/rss+xml"></data> </intent-filter> </activity> The application no longer claims to be able to run rss files. Also, if I change the line to: <data android:mimeType="application/xml"></data> It also won't work (for generic xml file even). So what intent filter do I need to make in order to claim that the activity supports rss. (Also, bonus points if you can tell me how I know what URL it was the user opened. So far, I've always sent that information from one activity to the other using extras). Thank you for your help

• What IPC method should I use between Firefox extension and C# code running on the same machine?

  - by Rory

  I have a question about how to structure communication between a (new) Firefox extension and existing C# code. The firefox extension will use configuration data and will produce other data, so needs to get the config data from somewhere and save it's output somewhere. The data is produced/consumed by existing C# code, so I need to decide how the extension should interact with the C# code. Some pertinent factors: It's only running on windows, in a relatively controlled corporate environment. I have a windows service running on the machine, built in C#. Storing the data in a local datastore (like sqlite) would be useful for other reasons. The volume of data is low, e.g. 10kb of uncompressed xml every few minutes, and isn't very 'chatty'. The data exchange can be asynchronous for the most part if not completely. As with all projects, I have limited resources so want an option that's relatively easy. It doesn't have to be ultra-high performance, but shouldn't add significant overhead. I'm planning on building the extension in javascript (although could be convinced otherwise if really necessary) Some options I'm considering: use an XPCOM to .NET/COM bridge use a sqlite db: the extension would read from and save to it. The c# code would run in the service, populating the db and then processing data created by the service. use TCP sockets to communicate between the extension and the service. Let the service manage a local data store. My problem with (1) is I think this will be tricky and not so easy. But I could be completely wrong? The main problem I see with (2) is the locking of sqlite: only a single process can write data at a time so there'd be some blocking. However, it would be nice generally to have a local datastore so this is an attractive option if the performance impact isn't too great. I don't know whether (3) would be particularly easy or hard ... or what approach to take on the protocol: something custom or http. Any comments on these ideas or other suggestions? UPDATE: I was planning on building the extension in javascript rather than c++

• Is this a pattern? Should it be?

  - by Arkadiy

  The following is more of a statement than a question - it describes something that may be a pattern. The question is: is this a known pattern? Or, if it's not, should it be? I've had a situation where I had to iterate over two dissimilar multi-layer data structures and copy information from one to the other. Depending on particular use case, I had around eight different kinds of layers, combined in about eight different combinations: A-B-C B-C A-C D-E A-D-E and so on After a few unsuccessful attempts to factor out the repetition of per-layer iteration code, I realized that the key difficulty in this refactoring was the fact that the bottom level needed access to data gathered at higher levels. To explicitly accommodate this requirement, I introduced IterationContext class with a number of get() and set() methods for accumulating the necessary information. In the end, I had the following class structure: class Iterator { virtual void iterateOver(const Structure &dataStructure1, IterationContext &ctx) const = 0; }; class RecursingIterator : public Iterator { RecursingIterator(const Iterator &below); }; class IterateOverA : public RecursingIterator { virtual void iterateOver(const Structure &dataStructure1, IterationContext &ctx) const { // Iterate over members in dataStructure1 // locate corresponding item in dataStructure2 (passed via context) // and set it in the context // invoke the sub-iterator }; class IterateOverB : public RecursingIterator { virtual void iterateOver(const Structure &dataStructure1, IterationContext &ctx) const { // iterate over members dataStructure2 (form context) // set dataStructure2's item in the context // locate corresponding item in dataStructure2 (passed via context) // invoke the sub-iterator }; void main() { class FinalCopy : public Iterator { virtual void iterateOver(const Structure &dataStructure1, IterationContext &ctx) const { // copy data from structure 1 to structure 2 in the context, // using some data from higher levels as needed } } IterationContext ctx(dateStructure2); IterateOverA(IterateOverB(FinalCopy())).iterate(dataStructure1, ctx); } It so happens that dataStructure1 is a uniform data structure, similar to XML DOM in that respect, while dataStructure2 is a legacy data structure made of various structs and arrays. This allows me to pass dataStructure1 outside of the context for convenience. In general, either side of the iteration or both sides may be passed via context, as convenient. The key situation points are: complicated code that needs to be invoked in "layers", with multiple combinations of layer types possible at the bottom layer, the information from top layers needs to be visible. The key implementation points are: use of context class to access the data from all levels of iteration complicated iteration code encapsulated in implementation of pure virtual function two interfaces - one aware of underlying iterator, one not aware of it. use of const & to simplify the usage syntax.

• jQuery mobile ajax login form authentication

  - by Jakub Zak

  I know i already asked simillar question, but now when I work with jQuery Mobile I can't figure it out. So I have this form: <div data-role="page" data-theme="a" id="login_page"> <div data-role="header" data-position="fixed"> <h1>****</h1> </div> <div data-role="content"> <form id="login_form" method="POST" data-ajax="false"> <label for="basic">Username:</label> <input type="text" name="name" id="username" value=""/> <label for="basic">Password:</label> <input type="password" name="password" id="password" value=""/> <input type="submit" value="Login" id="login" name="login"/> </form> </div> <div data-role="footer" data-position="fixed"> <div data-role="navbar"></div> </div> </div> And I need to submit Username and Password to php script, where php replies and send "success" or "failed". Here is php: <?php session_start(); $username = $_POST["name"]; $password = $_POST["password"]; include('mysql_connection.php'); mysql_select_db("jzperson_imesUsers", $con); $res1 = mysql_query("SELECT * FROM temp_login WHERE username='$username' AND password='$password'"); $count=mysql_num_rows($res1); if($count==1){ echo "success"; }else{ echo "failed"; } ?> And to do all this I want to use this script: $(document).ready(function() { $("form").submit(function(){ $.mobile.showPageLoadingMsg(); $.ajax({ url: "http://imes.jzpersonal.com/login_control.php", type: "POST", dataType: "jsonp", jsonp: "jsoncallback", data: $("form#login_form").serialize(), success: function( response ){ $.mobile.changePage( "http://imes.jzpersonal.com/user_panel.html"); } }); return false; }); }); But I can't make it work, I know I must have mistakes in there, I just can't find them, or better way to do it. Thank you in advance for any help.

• AJAX: Problems returning multiple variables

  - by fwaokda

  First off sorry if I'm missing something simple just started working with AJAX today. I have an issue where I'm trying to get information from my database, but different records have different amounts of values. For instance, each record has a "features" column. In the features column I store a string. (ex: Feature1~Feature2~Feature3~Feature4... ) When I'm building the object I take apart the string and store all the features into an array. Some objects can have 1 feature others can have up to whatever. So... how do I return this values back to my ajax function from my php page? Below is my ajax function that I was trying and I'll provide a link with my php file. [ next.php : http://pastebin.com/SY74jV7X ] $("a#next").click(function() { $.ajax({ type : 'POST', url : 'next.php', dataType : 'json', data : { nextID : $("a#next").attr("rel") }, success : function ( data ) { var lastID = $("a#next").attr("rel"); var originID = $("a#next").attr("rev"); if(lastID == 1) { lastID = originID; } else { lastID--; } $("img#spotlight").attr("src",data.spotlightimage); $("div#showcase h1").text(data.title); $("div#showcase h2").text(data.subtitle); $("div#showcase p").text(data.description); $("a#next").attr("rel", lastID); for(var i=0; i < data.size; i++) { $("ul#features").append("<li>").text(data.feature+i).append("</li>"); } /* for(var j=1; j < data.picsize; j++) { $("div.thumbnails ul").append("<li>").text(data.image+j).append("</li>"); } */ }, error : function ( XMLHttpRequest, textStatus, errorThrown) { $("div#showcase h1").text("An error has occured: " + errorThrown); } }); });

• problem with JsonStore and JsonReader

  - by kalan

  Hello, In my ExtJS application I use EditorGridPanel to show data from server. var applicationsGrid = new Ext.grid.EditorGridPanel({ region: 'west', layout: 'fit', title: '<img src="../../Content/img/app.png" /> ??????????', collapsible: true, margins: '0 0 5 5', split: true, width: '30%', listeners: { 'viewready': { fn: function() { applicationsGridStatusBar.setText('??????????: ' + applicationsStore.getTotalCount()); } } }, store: applicationsStore, loadMask: { msg: '????????...' }, sm: new Ext.grid.RowSelectionModel({ singleSelect: true, listeners: { 'rowselect': { fn: applicationsGrid_onRowSelect} } }), viewConfig: { forceFit: true }, tbar: [{ icon: '../../Content/img/add.gif', text: '????????' }, '-', { icon: '../../Content/img/delete.gif', text: '???????' }, '-'], bbar: applicationsGridStatusBar, columns: [{ header: '??????????', dataIndex: 'ApplicationName', tooltip: '???????????? ??????????', sortable: true, editor: { xtype: 'textfield', allowBlank: false } }, { header: '<img src="../../Content/img/user.png" />', dataIndex: 'UsersCount', align: 'center', fixed: true, width: 50, tooltip: '?????????? ????????????? ??????????', sortable: true }, { header: '<img src="../../Content/img/role.gif" />', dataIndex: 'RolesCount', align: 'center', fixed: true, width: 50, tooltip: '?????????? ????? ??????????', sortable: true}] }); When I use JsonStore without reader it works, but when I try to update any field it uses my 'create' url instead of 'update'. var applicationsStore = new Ext.data.JsonStore({ root: 'applications', totalProperty: 'total', idProperty: 'ApplicationId', messageProperty: 'message', fields: [{ name: 'ApplicationId' }, { name: 'ApplicationName', allowBlank: false }, { name: 'UsersCount', allowBlank: false }, { name: 'RolesCount', allowBlank: false}], id: 'app1234', proxy: new Ext.data.HttpProxy({ api: { create: '/api/applications/getapplicationslist1', read: '/api/applications/getapplicationslist', update: '/api/applications/getapplicationslist2', destroy: '/api/applications/getapplicationslist3' } }), autoSave: true, autoLoad: true, writer: new Ext.data.JsonWriter({ encode: false, listful: false, writeAllFields: false }) }); I believe that the problem is that I don't use reader, but when I use JsonReader grid stops showing any data at all. var applicationReader = new Ext.data.JsonReader({ root: 'applications', totalProperty: 'total', idProperty: 'ApplicationId', messageProperty: 'message', fields: [{ name: 'ApplicationId' }, { name: 'ApplicationName', allowBlank: false }, { name: 'UsersCount', allowBlank: false }, { name: 'RolesCount', allowBlank: false}] }); var applicationsStore = new Ext.data.JsonStore({ id: 'app1234', proxy: new Ext.data.HttpProxy({ api: { create: '/api/applications/getapplicationslist1', read: '/api/applications/getapplicationslist', update: '/api/applications/getapplicationslist2', destroy: '/api/applications/getapplicationslist3' } }), reader: applicationReader, autoSave: true, autoLoad: true, writer: new Ext.data.JsonWriter({ encode: false, listful: false, writeAllFields: false }) }); So, does anyone know what the problem might be and how to solve it. The data returned from my server is Json-formated and seams to be ok {"message":"test","total":2,"applications":[{"ApplicationId":"f82dc920-17e7-45b5-98ab-03416fdf52b2","ApplicationName":"Archivist","UsersCount":6,"RolesCount":3},{"ApplicationId":"054e2e78-e15f-4609-a9b2-81c04aa570c8","ApplicationName":"Test","UsersCount":1,"RolesCount":0}]}

  I want to select data from one table (T1, in DB1) in one server (Data.Old.S1) into data in another table (T2, in DB2) in another server (Data.Latest.S2). How can I do this ? Please note the way the servers are named. The query should take care of that too. That is, SQL server should not be confused about fully qualified table names. For example - this could confuse SQL server - Data.Old.S1.DB1.dbo.T1.

• Global NSMutableArray doesn't seem to be holding values

  - by diatrevolo

  I have a Cocos2D iPhone application that requires a set of CGRects overlaid on an image to detect touches within them. "Data" below is a class that holds values parsed from an XML file. "delegateEntries" is a NSMutableArray that contains several "data" objects, pulled from another NSMutableArray called "entries" that lives in the application delegate. For some strange reason, I can get at these values without problems in the init function, but further down the class in question, I try to get at these values, and the application crashes without an error message (as an example, I put in the "ccTouchBegan" method which accessess this data through the "populateFieldsForTouchedItem" method. Can anyone see why these values would not be accessible from other methods? No objects get released until dealloc. Thanks in advance! @synthesize clicked, delegate, data, image, blurImage, normalImage, arrayOfRects, delegateEntries; - (id)initWithTexture:(CCTexture2D *)aTexture { if( (self=[super initWithTexture:aTexture] )) { arrayOfRects = [[NSMutableArray alloc] init]; delegateEntries = [[NSMutableArray alloc] init]; delegate = (InteractivePIAppDelegate *)[[UIApplication sharedApplication] delegate]; delegateEntries = [delegate entries]; data = [delegateEntries objectAtIndex:0]; NSLog(@"Assigning %@", [[delegateEntries objectAtIndex:0] backgroundImage]); NSLog(@"%@ is the string", [[data sections] objectAtIndex:0]); //CGRect rect; NSLog(@"Count of array is %i", [delegateEntries count]); //collect as many items as there are XML entries for(int i=0; i<[delegateEntries count]; i++) { if([[delegateEntries objectAtIndex:i] xPos]) { NSLog(@"Found %i items", i+1); [arrayOfRects addObject:[NSValue valueWithCGRect:CGRectMake([[[delegateEntries objectAtIndex:i] xPos] floatValue], [[[delegateEntries objectAtIndex:i] yPos] floatValue], [[[delegateEntries objectAtIndex:i] xBounds] floatValue], [[[delegateEntries objectAtIndex:i] yBounds] floatValue])]]; } else { NSLog(@"Nothing"); } } //remove the following once the NSMutableArray from above works (legacy) blurImage = [[NSString alloc] initWithString:[data backgroundBlur]]; NSLog(@"5"); normalImage = [[NSString alloc] initWithString:[data backgroundImage]]; clicked = NO; } return self; } And then: - (void)populateFieldsForTouchedItem:(TouchedRect)touchInfo { Data *touchDatum = [[Data alloc] init]; touchDatum = [[self delegateEntries] objectAtIndex:touchInfo.recordNumber]; NSLog(@"Assigning %@", [[[self delegateEntries] objectAtIndex:touchInfo.recordNumber] backgroundImage]); rect = [[arrayOfRects objectAtIndex:touchInfo.recordNumber] CGRectValue]; image = [[NSString alloc] initWithString:[[touchDatum sections] objectAtIndex:0]]; [touchDatum release]; } - (BOOL)ccTouchBegan:(UITouch *)touch withEvent:(UIEvent *)event { TouchedRect touchInfo = [self containsTouchLocation:touch]; NSLog(@"Information pertains to %i", touchInfo.recordNumber); if ( !touchInfo.touched && !clicked ) { //needed since the touch location changes when zoomed NSLog(@"NOPE"); return NO; } [self populateFieldsForTouchedItem:touchInfo]; NSLog(@"YEP"); return YES; }

• C#, LINQ. How to find an element within group of elements

  - by Bobb

  Imagine you have int[] data = new int [] { 1, 2, 1, 1, 3, 2 } I need sub-array with only those which conform to a condition data[i] data[i-1] && data[i] data[i + 1]... i.e. I need all items which stick over their immediate neighbours. From example above I should get { 2, 3 } Can it be done in LINQ? Thanks
