  • How to set text in Y-axis, instead of numbers, in a RadChart component from Telerik with Bar-type

    - by radbyx
    Hi, I have made an bar RadChart with "SeriesOrientation="Horizontal"". I have the text showing at the end for each bars, but instead I would like that text to be listet in the y-axis, instead of the 1,2,3.. numbers. It seems like i'm not allow to set any text in the y-axis, is there a property I can set? Here is my code snippes: === .ascx === <asp:UpdatePanel ID="UpdatePanel1" runat="server"> <ContentTemplate> <telerik:RadChart ID="RadChart1" runat="server" Skin="WebBlue" AutoLayout="true" Height="350px" Width="680px" SeriesOrientation="Horizontal"> <Series> <telerik:ChartSeries DataYColumn="UnitPrice" Name="Product Unit Price"> </telerik:ChartSeries> </Series> <PlotArea> <YAxis> <Appearance> <TextAppearance TextProperties-Font="Verdana, 8.25pt, style=Bold" /> </Appearance> </YAxis> <XAxis DataLabelsColumn="TenMostExpensiveProducts"> </XAxis> </PlotArea> <ChartTitle> <TextBlock Text="Ten Most Expensive Products" /> </ChartTitle> </telerik:RadChart> </ContentTemplate> </asp:UpdatePanel> ========================= === .ascx === protected void Page_Load(object sender, EventArgs e) { RadChart1.AutoLayout = false; RadChart1.Legend.Visible = false; // Create a ChartSeries and assign its name and chart type ChartSeries chartSeries = new ChartSeries(); chartSeries.Name = "Name"; chartSeries.Type = ChartSeriesType.Bar; // add new items to the series, // passing a value and a label string chartSeries.AddItem(98, "Product1"); chartSeries.AddItem(95, "Product2"); chartSeries.AddItem(100, "Product3"); chartSeries.AddItem(75, "Product4"); chartSeries.AddItem(1, "Product5"); // add the series to the RadChart Series collection RadChart1.Series.Add(chartSeries); // add the RadChart to the page. // this.Page.Controls.Add(RadChart1); // RadChart1.Series[0].Appearance.LegendDisplayMode = ChartSeriesLegendDisplayMode.Nothing; // RadChart1.Series[0].DataYColumn = "Uptime"; RadChart1.PlotArea.XAxis.DataLabelsColumn = "Name"; RadChart1.PlotArea.XAxis.Appearance.TextAppearance.TextProperties.Font = new System.Drawing.Font("Verdana", 8); RadChart1.BackColor = System.Drawing.Color.White; RadChart1.Height = 350; RadChart1.Width = 570; RadChart1.DataBind(); } I want to have the text: "Product1", "Product2", ect in the y-axis, can anyone help?

  • How much time should it take to find the sum of all prime numbers less than 2 million?

    - by Shahensha
    I was trying to solve this Project Euler Question. I implemented the sieve of euler as a helper class in java. It works pretty well for the small numbers. But when I input 2 million as the limit it doesn't return the answer. I use Netbeans IDE. I waited for a lot many hours once, but it still didn't print the answer. When I stopped running the code, it gave the following result Java Result: 2147483647 BUILD SUCCESSFUL (total time: 2,097 minutes 43 seconds) This answer is incorrect. Even after waiting for so much time, this isn't correct. While the same code returns correct answers for smaller limits. Sieve of euler has a very simple algo given at the botton of this page. My implementation is this: package support; import java.util.ArrayList; import java.util.List; /** * * @author admin */ public class SieveOfEuler { int upperLimit; List<Integer> primeNumbers; public SieveOfEuler(int upperLimit){ this.upperLimit = upperLimit; primeNumbers = new ArrayList<Integer>(); for(int i = 2 ; i <= upperLimit ; i++) primeNumbers.add(i); generatePrimes(); } private void generatePrimes(){ int currentPrimeIndex = 0; int currentPrime = 2; while(currentPrime <= Math.sqrt(upperLimit)){ ArrayList<Integer> toBeRemoved = new ArrayList<Integer>(); for(int i = currentPrimeIndex ; i < primeNumbers.size() ; i++){ int multiplier = primeNumbers.get(i); toBeRemoved.add(currentPrime * multiplier); } for(Integer i : toBeRemoved){ primeNumbers.remove(i); } currentPrimeIndex++; currentPrime = primeNumbers.get(currentPrimeIndex); } } public List getPrimes(){ return primeNumbers; } public void displayPrimes(){ for(double i : primeNumbers) System.out.println(i); } } I am perplexed! My questions is 1) Why is it taking so much time? Is there something wrong in what I am doing? Please suggest ways for improving my coding style, if you find something wrong.

  • Sending string to wcf service using jquery ajax. why can i only send strings of numbers?

    - by Robodude
    Hi Guys, For some reason, I'm only able to pass strings containing numbers to my web service when using jquery ajax. This hasn't been an issue so far because I was always just passing IDs to my wcf service. But I'm trying to do something more complex now but I can't figure it out. In my interface: [OperationContract] [WebInvoke(ResponseFormat = WebMessageFormat.Json)] DataTableOutput GetDataTableOutput(string json); My webservice: public DataTableOutput GetDataTableOutput(string json) { DataTableOutput x = new DataTableOutput(); x.iTotalDisplayRecords = 9; x.iTotalRecords = 50; x.sColumns = "1"; x.sEcho = "1"; x.aaData = null; return x; } Javascript/Jquery: var x = "1"; $.ajax({ type: "POST", async: false, url: "Services/Service1.svc/GetDataTableOutput", contentType: "application/json; charset=utf-8", data: x, dataType: "json", success: function (msg) { }, error: function (XMLHttpRequest, textStatus, errorThrown) { //alert(XMLHttpRequest.status); //alert(XMLHttpRequest.responseText); } }); The above code WORKS perfectly. But when I change x to "t" or even to "{'test':'test'}" I get a Error 400 Bad Request error in Firebug. Thanks, John EDIT: Making some progress! data: JSON.stringify("{'test':'test'}"), Sends the string to my function! EDIT2: var jsonAOData = JSON.stringify(aoData); $.ajax({ type: "POST", async: false, url: sSource, contentType: "application/json; charset=utf-8", data: "{'Input':" + jsonAOData + "}", dataType: "json", success: function (msg) { }, error: function (XMLHttpRequest, textStatus, errorThrown) { //alert(XMLHttpRequest.status); //alert(XMLHttpRequest.responseText); } }); EDIT3: I modified the code block I put in EDIT2 up above. Swapping the " and ' did the trick! $.ajax({ type: "POST", async: false, url: sSource, contentType: "application/json; charset=utf-8", data: '{"Input":' + jsonAOData + '}', dataType: "json", success: function (msg) { }, error: function (XMLHttpRequest, textStatus, errorThrown) { //alert(XMLHttpRequest.status); //alert(XMLHttpRequest.responseText); } }); However, I have a new problem: public DataTableOutput GetDataTableOutput(DataTableInputOverview Input) { The input here is completely null. The values I passed from jsonAOData didn't get assigned to the DataTableInputOverview Input variable. :(

  • LINQ – TakeWhile and SkipWhile methods

    - by nmarun
    I happened to read about these methods on Vikram's blog and tried testing it. Somehow when I saw the output, things did not seem to add up right. I’m writing this blog to show the actual workings of these methods. Let’s take the same example as showing in Vikram’s blog and I’ll build around it. 1: int[] numbers = { 5, 4, 1, 3, 9, 8, 6, 7, 2, 0 }; 2:  3: foreach(var number in numbers.TakeWhile(n => n < 7)) 4: { 5: Console.WriteLine(number); 6: } Now, the way I (incorrectly) read the upper bound condition in the foreach loop was: ‘Give me all numbers that pass the condition of n<7’. So I was expecting the answer to be: 5, 4, 1, 3, 2, 0. But when I run the application, I see only: 5, 4, 1,3. Turns out I was wrong (happens at least once a day). The documentation on the method says ‘Returns elements from a sequence as long as a specified condition is true. To show in code, my interpretation was the below code’: 1: foreach (var number in numbers) 2: { 3: if (number < 7) 4: { 5: Console.WriteLine(number); 6: } 7: } But the actual implementation is: 1: foreach(var number in numbers) 2: { 3: if(number < 7) 4: { 5: Console.WriteLine(number); 6: break; 7: } 8: } So there it is, another situation where one simple word makes a difference of a whole world. The SkipWhile method has been implemented in a similar way – ‘Bypasses elements in a sequence as long as a specified condition is true and then returns the remaining elements’ and not ‘Bypasses elements in a sequence where a specified condition is true and then returns the remaining elements’. (Subtle.. very very subtle). It’s feels strange saying this, but hope very few require to read this article to understand these methods.

  • MapItemsControls not updating Silverlight Bing Map

    - by Matt
    I'm using a MapItemsControl to control my Pushpin items within my Bing silverlight map. Right on the page load, I add a new pin programatically, and the pin shows up on the map. However I've now taken it further and I'm adding pins to my datasource via a click on the map. The new pins add to my datasource, but do not show up on the map. Do I need to rebind my datasource to my map control or somehow refresh the datasource? Here's some code <UserControl.Resources> <DataTemplate x:Key="PinData"> <m:Pushpin Location="{Binding Location}" PositionOrigin="BottomCenter" Width="Auto" Height="Auto" Cursor="Hand"> <m:Pushpin.Template> <ControlTemplate> <Grid> <myTestApp:MasterPin DataContext="{Binding}"/> </Grid> </ControlTemplate> </m:Pushpin.Template> </m:Pushpin> </DataTemplate> </UserControl.Resources> <Grid x:Name="LayoutRoot" Background="White"> <m:Map x:Name="myMap" CredentialsProvider="" Mode="Road" ScaleVisibility="Collapsed" > <m:MapItemsControl x:Name="mapItems" ItemTemplate="{StaticResource PinData}"/> </m:Map> </Grid> public partial class Map : UserControl { private List< BasePin > dataSource = new List< BasePin >(); public Map() { InitializeComponent(); _Initialize(); } private void _Initialize() { //this part works and adds a pin to the map dataSource.Add( new BaseSite( -33.881532, 18.440208 ) ); myMap.MouseClick += Map_MouseClick; mapItems.ItemsSource = dataSource; } public void Map_MouseClick(object sender, MapMouseEventArgs e)) { BasePin pin = new BasePin(); pin.Location = myMap.ViewportPointToLocation( e.ViewportPoint ); dataSource.Add( pin ); } }

  • How to Omit the Page Number From the First Page of a Word 2013 Document Without Using Sections

    - by Lori Kaufman
    Normally, the first page, or cover page, of a document does not have a page number or other header or footer text. You can avoid putting a page number on the first page using sections, but there is an easier way to do this. If you don’t plan to use sections in any other part of your document, you may want to avoid using them completely. We will show you how to easily take the page number off the cover page and start the page numbering at one on the second page of your document by simply using a footer (or a header) and changing one setting. Click the Page Layout tab. In the Page Setup section of the Page Layout tab, click the Page Setup dialog box launcher icon in the lower, right corner of the section. On the Page Setup dialog box, click the Layout tab and select the Different first page check box in the Headers and footers section so there is a check mark in the box. Click OK. You’ll notice there is no page number on the first page of your document now. However, you might want the second page to be page one of your document, only to find it is currently page two. To change the page number on the second page to one, click the Insert tab. In the Header & Footer section of the Insert tab, click Page Number and select Format Page Numbers from the drop-down menu. On the Page Number Format dialog box, select Start at in the Page numbering section. Enter 0 in the edit box and click OK. This allows the second page of your document to be labeled as page one. You can use the drop-down menu on the Format Page Numbers button in the Header & Footer section of the Insert tab to add page numbers to your document as well. Easily insert formatted page numbers at the top or bottom of the page or in the page margins. Use the same menu to remove page numbers from your document.

  • LINQ and Aggregate function

    - by vik20000in
    LINQ also provides with itself important aggregate function. Aggregate function are function that are applied over a sequence like and return only one value like Average, count, sum, Maximum etc…Below are some of the Aggregate functions provided with LINQ and example of their implementation. Count     int[] primeFactorsOf300 = { 2, 2, 3, 5, 5 };     int uniqueFactors = primeFactorsOf300.Distinct().Count();The below example provided count for only odd number.     int[] primeFactorsOf300 = { 2, 2, 3, 5, 5 };     int uniqueFactors = primeFactorsOf300.Distinct().Count(n => n%2 = 1);  Sum     int[] numbers = { 5, 4, 1, 3, 9, 8, 6, 7, 2, 0 };        double numSum = numbers.Sum();  Minimum      int minNum = numbers.Min(); Maximum      int maxNum = numbers.Max();Average      double averageNum = numbers.Average();  Aggregate      double[] doubles = { 1.7, 2.3, 1.9, 4.1, 2.9 };     double product = doubles.Aggregate((runningProduct, nextFactor) => runningProduct * nextFactor);  Vikram

  • Distribute Sort Sample Service

    - by kaleidoscope
    How it works? Using the front-end of the service, a user can specify a size in MB for the input data set to sort. Algorithm CreateAndSplit The CreateAndSplit task generates the input data and stores them as 10 blobs in the utility storage. The URLs to these blobs are packaged as Separate work items and written to the queue. · Separate The Separate task reads the blobs with the random numbers created in the CreateAndSplit task and places the random numbers into buckets. The interval of the numbers that go into one bucket is chosen so that the expected amount of numbers (assuming a uniform distribution of the numbers in the original data set) is around 100 kB. Each bucket is represented as a blob container in utility storage. Whenever there are 10 blobs in one bucket (i.e., the placement in this bucket is complete because we had 10 original splits), the separate task will generate a new Sort task and write the task into the queue. · Sort The Sort task merges all blobs in a single bucket and sorts them using a standard sort algorithm. The result is stored as a blob in utility storage. · Concat The concat task merges the results of all Sort tasks into a single blob. This blob can be downloaded as a text file using this Web page. As the resulting file is presented in text format, the size of the file is likely to be larger than the specified input file. Anish

  • How to remove an object from the canvas?

    - by Marius Jonsson
    Hello there, I am making this script that will rotate a needle on a tachometer using canvas. I am a newbie to this canvas. This is my code: function startup() { var canvas = document.getElementById('canvas'); var context = canvas.getContext('2d'); var meter = new Image(); meter.src = 'background.png'; var pin = new Image(); pin.src = 'needle.png'; context.drawImage(meter,0,0); context.translate(275,297); for (var frm = 0; frm < 6000; frm++){ var r=frm/1000; //handle here var i=r*36-27; //angle of rotation from value of r and span var angleInRadians = 3.14159265 * i/180; //converting degree to radian context.rotate(angleInRadians); //rotating by angle context.drawImage(pin,-250,-3); //adjusting pin center at meter center } } Here is the script in action: http://www.kingoslo.com/instruments/ The problem is, as you can see, that the red needle is not removed beetween each for-loop. What I need to do is to clear the canvas for the pin object between each cycle of the loop. How do I do this? Thanks. Kind regards, Marius

  • I hyperlinked a cell in excel 2003, formula issues?

    - by joseinsomniac
    I have a budget spreadsheet using excel 2003. I have My deposit, then all of my bills, the total, then a cell that has the difference(between the amount of deposit and the total of the bills). The difference cell numbers turn red when I dont have enough money (deposit vs bill total). I hyperlinked the difference cell to a checkbook register spreadsheet so I can track where all my extra money went(reconsile receipts daily). When hyperlinked the numbers are blue. I need the numbers to stay black(when above 0.00) and stay red (when the numbers are below 0.00) and not change after the link has been clicked on. Also if the link has not been clicked on, and the numbers are red, the font is smaller, even though the toolbar shows the font size hasnt changed. After I click on it and go back to the budget sheet, its the size it should be. Any Ideas? Thanks!

  • Can I tell if the iPhone has a passcode?

    - by tewha
    I'm developing an application that asks for a PIN when you start it. That's not great, but I can live with it. The problem is I'm being asked to ask for the PIN each time the phone wakes from sleep, too. Combined with the OS asking for its passcode, it's too much. Is there any legitimate way to detect if the phone has a passcode required for waking, so I can skip requiring a PIN in this case? I don't want to know the PIN and I don't actually care if it was locked (for instance, if the phone was asleep very briefly), I just want to know that the data is in some way "protected."

  • Is this an effective monetization method for an Android game? [on hold]

    - by Matthew Page
    The short version: I plan to make an Android puzzle game where the user tries to get 3-6 numbers to their predetermined goal numbers. The free version of the app will have three predetermined levels (easy, medium, hard). The full version ($0.99, probably) will have a level generator where there will be unlimited easy, medium, or hard levels, as well as a custom difficulty option where users can set specific vales to the number of numbers to equate to their goal, the number of buttons to use, etc. Users will also have the option to get a one-time "hint" for a fee of $0.49, or unlimited hints for a one-time fee of $2.99. The long version: Mechanics of Game and Victory The application is a number puzzle. When the user begins a new game, depending on the input by the user, between 3 and 6 numbers show up on the top of the screen, and between 3 and 6 buttons show up on the bottom of the screen. The buttons all have two options: to increase every number the same way, or decrease every number the same way. The buttons either use addition / subtraction, multiplication / division, or exponents / roots, all depending on the number displayed on the button. Addition buttons are green, multiplication buttons are blue, and exponential buttons are red. The user wins when all of the numbers displayed on the screen equate to their goal number, displayed below each number. Monetization If the user is playing the full (priced) version of the app, upon the start of the game, the user will be confronted with a dialogue asking for the number of buttons and the number of numbers to equate in the game. Then, based on the user input, a random puzzle will be generated. If the user is playing the free version of the app, the user will be asked to either play an “easy”, “hard”, or “expert” puzzle. A pre-determined puzzle from each category will be used in the game. If the user has played that puzzle before, a dialogue will show saying this to the user and advertising the full version of the app. The full version of the app will also be advertised upon the successful or in successful completion of a puzzle. Upon exiting this advertisement, another full screen advertisement will appear from a third party. Also, the solution to the puzzle should be stored by the program, and if the user pays a small fee, he/she can see a hint to the solution to the program. In the free version of the app, the user may use their first hint for free. Also, the user can use unlimited hints for a slightly larger fee. Is this an effective monetization method?

  • Converting application to MVC architecture

I have a Mastermind game, that I would like to rewrite as MVC app. I have divided my code to parts, but instead of working game I'm getting empty Frame and an error in "public void paint( Graphics g )".

  • LINQ – Skip() and Take() methods

    - by nmarun
    I had this issue recently where I have an array of integers and I’m doing some Skip(n) and then a Take(m) on the collection. Here’s an abstraction of the code: 1: int[] numbers = { 5, 4, 1, 3, 9, 8, 6, 7, 2, 0 }; 2: var taken = numbers.Skip(3).Take(3); 3: foreach (var i in taken) 4: { 5: Console.WriteLine(i); 6: } The output is as expected: 3, 9, 8 – skip the first three and then take the next three items. But, what happens if I do something like: 1: var taken = numbers.Skip(7).Take(5); In English – skip the first seven and the take the next 5 items from an array that contains only 10 elements. Think it’ll throw the IndexOutOfRangeException exception? Nope. These extension methods are a little smarter than that. Even though the user has requested more elements than what exists in the collection, the Take method only returns the first three thereby making the output of the program as: 7, 2, 0. The scenario is handled similarly when you do: 1: var taken = numbers.Take(5).Skip(7); This one takes the first 5 elements from the numbers array and then skips 7 of them. This is what is looks like in the debug mode: Just wanted to share this behavior.

  • Javascript/Jquery Super Scrollorama Navigation Issues

    - by Rosencruez
    On a Wordpress site I am currently working on, my client wanted the different sections of the front page to slide up from the bottom and cover up the previous section, like a wipe or slide transition. Using super scrollorama found here: http://johnpolacek.github.com/superscrollorama/, I managed to achieve the desired result. Next, I needed to create a navigation menu on the front page only. I did so, and set anchors at various different points on the pages. I also used the scrollTo library for scolling animations when I click the nav menu links. However, there are a number of problems I have encountered: When at the top and I click "showcase", it brings me down to the showcase section, but the products section (the div right after it) is overlapping it. Other divs seems to have the same problem of the following divs overlapping the current one I can only navigate forwards. When I try to go backwards, it won't (except for "Home") I thought it might have something to do with the CSS "top" property of the divs, so I tried resetting them every time the click function kicked in, but it didn't work. So I removed it for the time being. Currently set the javascript to prevent the default action of scrolling to the anchors and instead setting it to scroll to the actual divs themselves. However, I'm still having the same issues. Here is the site I am currently working on: http://breathe.simalam.ca/ Here is the javascript for the scrolling: $(document).ready(function() { jQuery('.home-link').click(function(e){ e.preventDefault(); jQuery(window).scrollTo(0, 1000, {queue:true}); }); jQuery('.showcase-link').click(function(e){ e.preventDefault(); jQuery(window).scrollTo('#showcase_content', 1000, {queue:true}); }); jQuery('.products-link').click(function(e){ e.preventDefault(); jQuery(window).scrollTo('#products_content', 1000, {queue:true}); }); jQuery('.about-link').click(function(e){ e.preventDefault(); jQuery(window).scrollTo('#about_content', 1000, {queue:true}); }); jQuery('.locator-link').click(function(e){ e.preventDefault(); jQuery(window).scrollTo('#locator_content', 1000, {queue:true}); }); jQuery('.contact-link').click(function(e){ e.preventDefault(); jQuery(window).scrollTo('#contact_content', 1000, {queue:true}); }); }); scrollorama code: $(document).ready(function() { $('#wrapper').css('display','block'); var controller = $.superscrollorama(); var pinDur = 4000; /* set duration of pin scroll in pixels */ // create animation timeline for pinned element var pinAnimations = new TimelineLite(); pinAnimations .append([ TweenMax.to($('#showcase'), .5, {css:{top:0}}) ], .5) .append([ TweenMax.to($('#products'), .5, {css:{top:0}}) ], .5) .append([ TweenMax.to($('#about'), .5, {css:{top:0}}) ], .5) .append([ TweenMax.to($('#locator'), .5, {css:{top:0}}) ], .5) .append([ TweenMax.to($('#contact'), .5, {css:{top:0}}) ], .5) .append(TweenMax.to($('#pin-frame-unpin'), .5, {css:{top:'100px'}})); controller.pin($('#examples-pin'), pinDur, { anim:pinAnimations, onPin: function() { $('#examples-pin').css('height','100%'); }, onUnpin: function() { $('#examples-pin').css('height','2000px'); } }); }); All of the section divs are inside a parent div. The section divs all have a height, width, and top of 100%. The parent div containing all of these section divs are as follows: #examples-pin { position: relative; /* relative positioning for transitions to work? */ width: 101%; /* max width */ height: 2000px; /* height of 2000px for now */ overflow: hidden; /* hide the overflow for transitions to work */ margin-bottom: -200px; /* negative bottom margin */ }

    Hi I have my own data structure written in C# like: public class ElectricScheme { public List<Element> Elements { get; set; } public List<Net> Nets { get; set; } } public class Element { public string IdName { get; set; } public string Func { get; set; } public string Name { get; set; } public BaseElementType Type { get; set; } public List<Pin> Pins { get; set; } } public class Pin { public string IdName { get; set; } public string Name { get; set; } public BasePinType PinType { get; set; } public BasePinDirection PinDirection { get; set; } } public class Net { public string IdName { get; set; } public string Name { get; set; } public List<Tuple<Element,Pin>> ConnectionPoints { get; set; } } Where Elements count ~19000, each element contain =3 Pin, Nets count ~20000, each net contain =3 pair (Element, Pin) Parse txt (file size ~17mb) file takes 5 minutes. Serilization / Deserialization by default serializer ~3 minutes. Load from DB 20 minutes and not loaded... I use Entity Framework like public ElectricScheme LoadScheme(int schemeId) { var eScheme = (from s in container.ElectricSchemesSet where s.IdElectricScheme.Equals(schemeId) select s).FirstOrDefault(); if (eScheme == null) return null; container.LoadProperty(eScheme, "Elements"); container.LoadProperty(eScheme, "Nets"); container.LoadProperty(eScheme, "Elements.Pins"); return eScheme; } The problem is dependencies between Element and Pin... (for ~19000 elements ~95000 pins) Any ideas?

  • Why do System.IO.Log SequenceNumbers have variable length?

    - by Doug McClean
    I'm trying to use the System.IO.Log features to build a recoverable transaction system. I understand it to be implemented on top of the Common Log File System. The usual ARIES approach to write-ahead logging involves persisting log record sequence numbers in places other than the log (for example, in the header of the database page modified by the logged action). Interestingly, the documentation for CLFS says that such sequence numbers are always 64-bit integers. Confusingly, however, the .Net wrapper around those SequenceNumbers can be constructed from a byte[] but not from a UInt64. It's value can also be read as a byte[], but not as a UInt64. Inspecting the implementation of SequenceNumber.GetBytes() reveals that it can in fact return arrays of either 8 or 16 bytes. This raises a few questions: Why do the .Net sequence numbers differ in size from the CLFS sequence numbers? Why are the .Net sequence numbers variable in length? Why would you need 128 bits to represent such a sequence number? It seems like you would truncate the log well before using up a 64-bit address space (16 exbibytes, or around 10^19 bytes, more if you address longer words)? If log sequence numbers are going to be represented as 128 bit integers, why not provide a way to serialize/deserialize them as pairs of UInt64s instead of rather-pointlessly incurring heap allocations for short-lived new byte[]s every time you need to write/read one? Alternatively, why bother making SequenceNumber a value type at all? It seems an odd tradeoff to double the storage overhead of log sequence numbers just so you can have an untruncated log longer than a million terabytes, so I feel like I'm missing something here, or maybe several things. I'd much appreciate it if someone in the know could set me straight.

  • Replacing values using preg_replace

    - by Jeepstone
    I have a Joomla plugin (not important in this context), which is designed to take an input with a load of numbers (within a paragraph of text) and replace them with a series of s. My problem is that I need to do a preg_replace on my $article-text, but I don't know how to then apply the changes to the matched terms. I've seen the preg_replace_callback, but I don't know how I can call that within a function. function onPrepareContent( &$article, &$params, $limitstart ) { global $mainframe; // define the regular expression $pattern = "#{lotterynumbers}(.*?){/lotterynumbers}#s"; if(isset($article->text)){ preg_match($pattern, $article->text, $matches); $numbers = explode("," , $matches[1]); foreach ($numbers as $number) { echo "<div class='number'><span>" . $number . "</span></div>"; } }else{ $article->text = 'No numbers'; } return true; } AMENDED CODE: function onPrepareContent( &$article, &$params, $limitstart ) { global $mainframe; // define the regular expression $pattern = "#{lotterynumbers}(.*?){/lotterynumbers}#s"; if(isset($article->text)){ preg_match($pattern, $article->text, $matches); $numbers = explode("," , $matches[1]); foreach ($numbers as $number) { $numberlist[] = "<div class='number'><span>" . $number .
