  • String formatting in cocoa

    - by lostInTransit
    Hi I am trying to send some text in an email from my cocoa app (by using Mail.app). Initially I tried using HTML to send properly formatted text. But the mailto: URL does not support html tags (even after setting headers) So I decided to use formatted string (left-aligning of string) This is what I have in my mailto: link's body argument NSMutableString *emailBody = [NSMutableString stringWithFormat:@"|%-35s", [@"Name" UTF8String]]; [emailBody appendFormat:@"|%-18s", [@"Number" UTF8String]]; [emailBody appendString:@"|Notes\n"]; [emailBody appendString:@"----------------------------------------------------------------------------------------------------"]; for(int i = 0; i < [items count]; i++){ NSDictionary *props = [items objectAtIndex:i]; NSMutableString *emailData = [NSMutableString stringWithFormat:@"|%-35s", [[props valueForKey:@"name"] UTF8String]]; [emailData appendFormat:@"|$ %-16s", [[props valueForKey:@"number"] UTF8String]]; [emailData appendString:[props valueForKey:@"notes"]]; [emailBody appendString:@"\n"]; [emailBody appendString:emailData]; } This does give me padded text but they all don't necessarily take up the same space (for instance if there is an O in the text, it takes up more space than others and ruins the formatting) Is there another sure-shot way to format text using just NSString? Thanks

  • How to hide UIStatusBar and show UINavigationBar at the top when UIView changes to LandscapeOrientat

    - by KayKay
    I am using two views (portraitView and landscapeView) loaded from xib in a viewcontroller for different InterfaceOrientation each for Portrait and Landscape mode. The view in portrait mode has statusbar and navigationbar and other one has just the navigationbar. The problem is that even i made statusbar hidden programatically the view in Landscape mode has blank space left at the position of statusbar and below is navigationbar which is for sure looking embarrassing. Is it possible to put the navigationbar at the top - replacing the statusbar position. I tried many options like. if (interfaceOrientation == UIInterfaceOrientationLandscapeLeft || interfaceOrientation == UIInterfaceOrientationLandscapeRight) { [[UIApplication sharedApplication] setStatusBarHidden:YES animated:NO]; self.navigationController.navigationBarHidden = NO; [[self view] setFrame:CGRectMake(0, 0, 480, 320)]; self.navigationController.wantsFullScreenLayout = YES; self.view = self.landscapeView; } But despite all this efforts it only lefts the same 20x480 pixels blank space and below it navigationbar. But here there is no end to trouble when I switch back to portraitView, the navigation bar hides behind the statusbar mere showing remaining 320x(44-20)px on top. Please help and thanks in advance.

  • MSDeploy migrate only configuration from IIS 6 to 7

    - by Matt
    We have 19 websites, many of which have many "virtual" directories, on a IIS 6 server. I am trying to migrate the whole thing over to IIS 7 on a different server. Following the instructions on http://learn.iis.net/page.aspx/427/migrate-a-web-site-from-iis-60-to-iis-70/ I attempted the following command line execution: msdeploy -verb:sync -source:metakey=lm/w3svc -dest:package=D:\Temp\Sites.zip > D:\temp\WebDeployPackage.log It appeared to be working until I got a "There is not enough space on the disk" error. The D drive, which you'll notice is the target location for the package and the log has plenty of space (all the resources for the websites are about 5gb, the drive has 200+). Though the C drive is of limited size (6Gb), so that might be the problem. Anyway, I figure the best bet was to try and do a migration of settings/configurations only, not the actual resources. We can easily deploy the resources to the new server with our NAnt build scripts, so that's not an issue. Getting all the correct configurations moved over, however, would be challenging to do manually. So, is there a way to export/package only the configuration/options of the IIS 6 server using msdeploy (or any other tool?)

  • Confused about home screen widget size in normal screen and larget screen

    - by kknight
    I am designing a home screen widget. The widget layout file is like below. <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/widget" android:layout_width="240dip" android:layout_height="200dip" android:background="@drawable/base_all" /> I ran this widget on a HTC Hero device, which has a screen of 320 pixels * 480 pixels with mdpi. It ran perfect on HTC Hero. The widget takes 3 cells * 2 cells space, i.e. 240 pixels * 200 pixels. Then I ran this widget on a Nexus One device, which has a screen of 480 pixels * 800 pixels, mdpi. Since Nexus One also is mdpi, so I though 240dip is equivalent to 240 pixels on Nexus One and 200dip is equivalent to 200 pixels on Nexus One, so the widget will not take 3 cells * 2 cells space on Nexus One device. To my surprise, when running on Nexus One device, the widget take exact 3 cells * 2 cells, about 360 pixels * 300 pixels, on Nexus One device. I am confused. The layout xml above specifies 240dip in width and 200dip in height for the widget, but why did it take 360 pixels * 300 pixels on Nexus One Device? What am I missing? Thanks.

  • How to convert datatable to json string using json.net?

    - by Pandiya Chendur
    How to convert datatable to json using json.net? Any suggestion... I ve downloaded the necessary binaries... Which class should i use to get the conversion of my datatable to json? Thus far used this method to get json string by passing my datatable... public string GetJSONString(DataTable table) { StringBuilder headStrBuilder = new StringBuilder(table.Columns.Count * 5); //pre-allocate some space, default is 16 bytes for (int i = 0; i < table.Columns.Count; i++) { headStrBuilder.AppendFormat("\"{0}\" : \"{0}{1}¾\",", table.Columns[i].Caption, i); } headStrBuilder.Remove(headStrBuilder.Length - 1, 1); // trim away last , StringBuilder sb = new StringBuilder(table.Rows.Count * 5); //pre-allocate some space sb.Append("{\""); sb.Append(table.TableName); sb.Append("\" : ["); for (int i = 0; i < table.Rows.Count; i++) { string tempStr = headStrBuilder.ToString(); sb.Append("{"); for (int j = 0; j < table.Columns.Count; j++) { table.Rows[i][j] = table.Rows[i][j].ToString().Replace("'", ""); tempStr = tempStr.Replace(table.Columns[j] + j.ToString() + "¾", table.Rows[i][j].ToString()); } sb.Append(tempStr + "},"); } sb.Remove(sb.Length - 1, 1); // trim last , sb.Append("]}"); return sb.ToString(); } Now i thought of using json.net but dont know where to get started....

  • WPF DataGrid HeaderTemplate Mysterious Padding

    - by Jake Wharton
    I am placing a single button with an image in the header of a column of a DataGrid. The cell template is also just a simple button with an image. <my:DataGridTemplateColumn> <my:DataGridTemplateColumn.HeaderTemplate> <DataTemplate> <Button ToolTip="Add New Template" Name="AddNewTemplate" Click="AddNewTemplate_Click"> <Image Source="../Resources/add.png"/> </Button> </DataTemplate> </my:DataGridTemplateColumn.HeaderTemplate> <my:DataGridTemplateColumn.CellTemplate> <DataTemplate> <Button ToolTip="Edit Template" Name="EditTemplate" Click="EditTemplate_Click" Tag="{Binding}"> <Image Source="../Resources/pencil.png"/> </Button> </DataTemplate> </my:DataGridTemplateColumn.CellTemplate> </my:DataGridTemplateColumn> When rendered, the header has approximately 10-15px of padding on the right side only which causes the cells to obviously render at that width leaving the cell button having empty space on both sides. Being a pixel-perfectionist this annoys the hell out of me. I had initially thought that it was space for the arrows displayed when sorted but I have sorting disabled on both the entire DataGrid and explicitly on the column. Here's a image: I assume this is padding form whatever is the parent element of the button. Does anyone know a way to eliminate it?

  • What is the target color profile in Image.FromFile?

    - by Jan Zich
    I am curious what the useEmbeddedColorManagement parameter in System.Drawing.Image.FromFile actually does. This parameter directory corresponds to a GDI+ parameter in the same method of the same class. So debugging .NET source does not lead anywhere. If my understanding of color profiles is correct, a color profile is basically a mapping which describes how particular RGB triples (or CMYK or something else) map into the so called Profile Connection Space (CIELAB or CIEXYZ). Now, if I open an image with embedded color in .NET setting useEmbeddedColorManagement to true, my experience is I get an image whose RGB values are not exactly the same as the original values in the file, i.e. is transformed. Since the original image was an RGB and the new is also an RGB, there must have been a transformation from the embedded color profile to a Profile Connection Space and the back to RGB. The thing which I don’t understand is what is the target color system? Is it some default Windows color profile? Is the current monitor profile? Is it sRGB?

  • Powershell: Select-Object with additional calculated difference value

    - by David.Chu.ca
    Let me explain my question. I have a daily report about one PC's free space as in text file (sp.txt) like: DateTime FreeSpace(MB) ----- ------------- 03/01/2010 100.43 DateTime FreeSpace(MB) ----- ------------- 03/02/2010 98.31 .... Then I need to use this file as input to generate a report with difference of free space between dates: DateTime FreeSpace(MB) Change ----- ------------- ------ 03/01/2010 100.43 03/02/2010 98.31 2.12 .... Here are some codes I have to get above result without the additional "Change" calculation: Get-Content "C:\report\sp.txt" ` | where {$_.trim().length -gt 0 -and -not ($_ -like "Date*") -and -not ($_ -like "---*")} ` | Select-Object @{Name='DateTime'; expression={[DateTime]::Parse($_.SubString(0, 10).Trim())}}, ` @{Name='FreeSpace(MB)'; expression={$_.SubString(12, 12).Trim()}}, ` | Sort-Object DateTime ` | Select-Object DateTime, 'FreeSpace(MB)' |ft -AutoSize # how to add additional column Change to this Select-Object? My understanding is that Select-Object will return a collection of objects. Here I create this collection from an input text file(parse each line into parts: datetime and freespace(MB)). In order to calculate the difference between dates, I guess that I need to add additional calculated value to the result of the last Select-Object, or pipe the result to another Select-Object with the calculation as additional property or column. In order to do it, I need to get the previous row's FreeSpace value. Not sure if it is possible and how?

  • Regex query: how can I search PDFs for a phrase where words in that phrase appear on more than one l

    - by Alison
    I am trying to set up an index page for the weekly magazine I work on. It is to show readers the names of companies mentioned in that weeks' issue, plus the page numbers they are appear on. I want to search all the PDF files for the week, where one PDF = one magazine page (originally made in Adobe InDesign CS3 and Adobe InCopy CS3). I have set up a list of companies I want to search for and, using PowerGREP and using delimited regular expressions, I am able to find most page numbers where a company is mentioned. However, where a company name contains two or more words, the search I am running will not pick up instances where the name appears over more than one line. For example, when looking for "CB Richard Ellis" and "Cushman & Wakefield", I got no result when the text appeared like this: DTZ beat BNP PRE, CB [line break here] Richard Ellis and Cushman & [line break here] Wakefield to secure the contract. [line end here] Could someone advise me on how to write a regular expression that will ignore white space between words and ignore line endings OR one that will look for the words including all types of white space (ie uneven spaces between words; spaces at the end of lines or line endings; and tabs (I am guessing that this info is imbedded somehow in PDF files). Here is a sample of the set of terms I have asked PowerGREP to search for: \bCB Richard Ellis\b \bCB Richard Ellis Hotels\b \bCentaur Services\b \bChapman Herbert\b \bCharities Property Fund\b \bChetwoods Architects\b \bChurch Commissioners\b \bClive Emson\b \bClothworkers’ Company\b \bColliers CRE\b \bCombined English Stores Group\b \bCommercial Estates Group\b \bConnells\b \bCooke & Powell\b \bCordea Savills\b \bCrown Estate\b \bCushman & Wakefield\b \bCWM Retail Property Advisors\b [Note that there is a delimited hard return between each \b at the end of each phrase and beginnong of the next phrase.] By the way, I am a production journalist and not usually involved in finding IT-type solutions and am finding it difficult to get to grips with the technical language on the PowerGREP site. Thanks for assistance Alison

  • How can I use Convert.ChangeType to convert string into numerics with group separator?

    - by Loic
    Hello, I want to make a generic string to numeric converter, and provide it as a string extension, so I wrote the following code: public static bool TryParse<T>( this string text, out T result, IFormatProvider formatProvider ) where T : struct try { result = (T)Convert.ChangeType( text, typeof( T ), formatProvider ); return true; } catch(... I call it like this: int value; var ok = "123".TryParse(out value, NumberFormatInfo.CurrentInfo) It works fine until I want to use a group separator: As I live in France, where the thousand separator is a space and the decimal separator is a comma, the string "1 234 567,89" should be equals to 1234567.89 (in Invariant culture). But, the function crashes! When a try to perform a non generic conversion, like double.Parse(...), I can use an overload which accepts a NumberStyles parameter. I specify NumberStyles.Number and this time it works! So, the questions are : Why the parsing does not respect my NumberFormatInfo (where the NumberGroupSeparator is well specified to a space, as I specified in my OS) How could I make work the generic version with Convert.ChangeTime, as it has no overload wich accepts a NumberStyles parameter ?

  • What's the best way to fill or paint around an image in Java?

    - by wsorenson
    I have a set of images that I'm combining into a single image mosaic using JAI's MosaicDescriptor. Most of the images are the same size, but some are smaller. I'd like to fill in the missing space with white - by default, the MosaicDescriptor is using black. I tried setting the the double[] background parameter to { 255 }, and that fills in the missing space with white, but it also introduces some discoloration in some of the other full-sized images. I'm open to any method - there are probably many ways to do this, but the documentation is difficult to navigate. I am considering converting any smaller images to a BufferedImage and calling setRGB() on the empty areas (though I am unsure what to use for the scansize on the batch setRGB() method). My question is essentially: What is the best way to take an image (in JAI, or BufferedImage) and fill / add padding to a certain size? Is there a way to accomplish this in the MosaicDescriptor call without side-effects? For reference, here is the code that creates the mosaic: for (int i = 0; i < images.length; i++) { images[i] = JPEGDescriptor.create(new ByteArraySeekableStream(images[i]), null); if (i != 0) { images[i] = TranslateDescriptor.create(image, (float) (width * i), null, null, null); } } RenderedOp finalImage = MosaicDescriptor.create(ops, MosaicDescriptor.MOSAIC_TYPE_OVERLAY, null, null, null, null, null);

  • shortest digest of a string

    - by meta
    [Description] Given a string of char type, find a shortest digest, which is defined as: a shortest sub-string which contains all the characters in the original string. [Example] A = "aaabedacd" B = "bedac" is the answer. [My solution] Define an integer table with 256 elements, which is used to record the occurring times for each kind of character in the current sub-string. Scan the whole string, statistic the total kinds of character in the given string by using the above table. Use two pointers, start, end, which are initially pointing to the start and (start + 1) of the given string. The current kinds of character is 1. Expand sub-string[start, end) at the end until it contains all kinds of character. Update the shortest digest if possible. Contract sub-string[start, end] at the start by one character each time, try to restore its digest property if necessary by step 4. The time cost is O(n), and the extra space cost is constant. Any better solution without extra space?

  • Over-enthusiastic Intellisense in VS2010 - can I tweak it?

    - by CJM
    Since I have upgraded from VS2008 to VS2010, I've been having an increasingly infuriating battle with the Intellisense. For example, when specifying CSS styles, when I press Enter to start an new line, Intellisense (appropriately) lists available Styles to me. And if I select color and then type ':', it presents a list of color presets - often helpful. However, if I type in a space (I like them for readability) or if I type '#' to enter RGB values, it selected the default Intellisense selection, in this case inherits. Another example is in an ASP.NET page - say I am concatenating strings, I type myString =, I get an Intellisense pop-up. If I type space or '"' (to enter a literal) or '.' (so select a property or method within a WITH block), the Intellisense selects the first entry in the list. I can dismiss the Intellisense pop-ups with escape but it makes it incredibly slow to code. This behaviour is different to my VS2008 set-up. I can't seem to find any way to configure Intellisense to behave differently... I really only want it to select and Intellisense entry when I type or ... at least, certainly not when I type '"' or ' ' or '.'!

  • Populate datagrid using Datacontext in C# WPF

    - by anon
    I'm trying to get data from file. The file first has three lines of text that describes the file, then there is a header for the data below. I've managed to extract that. What I'm having problems is getting the data below the header line. The data below the header line can look like "1 2 3 4 5 6 7 8 9 abc". DataGrid dataGrid1 = new DataGrid(); masterGrid.Children.Add(dataGrid1); using (TextReader tr = new StreamReader(@filename)) { int lineCount = 1; while (tr.Peek() >= 0) { string line = tr.ReadLine(); { string[] data = line.Trim().Split(' '); Dictionary<string, object> sensorData = new Dictionary<string, object>(); for (int i = 0, j = 0; i < data.Length; i++) { //I know that I'm delimiting the data by a space before. //but the data from the text file doesn't necessarily have //just one space between each piece of data //so if I don't do this, spaces will become part of the data. if (String.Compare(data[i]," ") > 0) { sensorData[head[j]] = data[i]; j++; } } sensorDatas.Add(sensorData); sensorData = null; } lineCount++; } } dataGrid1.DataContext = sensorDatas; I can't figure out why this doens't work. If I change "dataGrid1.DataContext = sensorDatas;" to "dataGrid1.ItemsSource = sensorDatas;" then I get the data in the proper columns, but I also get some Raw View data such as: Comparer, Count, Keys, Values as columns, which I don't want. Any insight?

  • WPF Grid Row / Column Sizing in Proportion to DesiredSize?

    - by sinibar
    I have two user controls arranged vertically in a grid, both of which can expand to be taller than the grid can accommodate. I've put them in each in a scrollviewer which functionally works. What I want though is to give them them space in proportion to the amount that they want at run time. So if there's 500 height available, the upper control wants 400 and the lower 600, the upper control would get 200 and the bottom 300. I have no idea at design time how much space each will want in proportion to the other, so using 1*, 2* etc. for row height won't work for me. I can hand-code run-time proportional sizing, but am I missing a simple trick in XAML that would get me what I want? Context is as follows (trimmed for brevity)... <Grid> <TabControl> <TabItem> <Grid> <Grid> <Grid.RowDefinitions> <RowDefinition Height="Auto"/> <RowDefinition Height="*"/> <RowDefinition Height="*"/> </Grid.RowDefinitions> <GroupBox Grid.Row="0" Header="Title Area" /> <ScrollViewer Grid.Row="1" VerticalScrollBarVisibility="Auto"> <UserControl /> </ScrollViewer> <ScrollViewer Grid.Row="2" VerticalScrollBarVisibility="Auto"> <UserControl /> </ScrollViewer> </Grid> </Grid> </TabItem> </TabControl> </Grid>

  • Regex to check if exact string exists including #

    - by Jayrox
    New question As suggested by Asaph in previous question: Regex to check if exact string exists I am looking for a way to check if an exact string match exists in another string using Regex or any better method suggested. I understand that you tell regex to match a space or any other non-word character at the beginning or end of a string. However, I don't know exactly how to set it up. Search String: #t String 1: Hello World, Nice to see you! #t String 2: Hello World, Nice to see you! String 3: #T Hello World, Nice to see you! I would like to use the search string and compare it to String 1, String 2 and String 3 and only get a positive match from String 1 and String 3 but not from String 2. Requirements: Search String may be at any character position in the Subject. There may or may not be a white-space character before or after it. I do not want it to match if it is part of another string; such as part of a word. For the sake of this question: I think I would do this using this pattern: /\b\#t\b/gi However, this is not returning the results as I would have expected. I am able to find the exact matches for normal strings (strings where # isn't present) using: /\b{$search_string}\b/gi Additional info: this will be used in PHP 5

  • PDF parsing file trailer

    - by Ralph
    It is not clear from the PDF ISO standard document (PDF32000-2008) whether a comment may follow the startxref keyword: startxref Byte_offset_of_last_cross-reference_section %%EOF The standard does seem to imply that comments may appear anywhere: 7.2.3 Comments Any occurrence of the PERCENT SIGN (25h) outside a string or stream introduces a comment. The comment consists of all characters after the PERCENT SIGN and up to but not including the end of the line, including regular, delimiter, SPACE (20h), and HORZONTAL TAB characters (09h). A conforming reader shall ignore comments, and treat them as single white-space characters. That is, a comment separates the token preceding it from the one following it. EXAMPLE The PDF fragment in this example is syntactically equivalent to just the tokens abc and 123. abc% comment ( /%) blah blah blah 123 Comments (other than the %PDF–n.m and %%EOF comments described in 7.5, "File Structure") have no semantics. They are not necessarily preserved by applications that edit PDF files. If they are allowed to appear after the startxref, parsing the file becomes more difficult because you do not know how far to back up from the %%EOF comment to start parsing to find the byte offset. Any ideas?

  • Can I include a NSUserDefault password test in AppDelegate to load a loginView?

    I have a name and password in NSUserDefaults for login. I want to place a test in my AppDelegate.m class to test for presence and load a login/signup loginView.xib modally if there is no password or name stored in the app. Here is the pulling of the defaults: -(void)refreshFields { NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults]; usernameLabel.text = [defaults objectForKey:kUsernameKey]; passwordLabel.text = [defaults objectForKey:kPasswordKey]; Here is the tabcontroller loading part: - (void)applicationDidFinishLaunching:(UIApplication *)application { firstTab = [[FirstTab alloc] initWithStyle:UITableViewStylePlain]; UINavigationController *firstNavigationController = [[UINavigationController alloc] initWithRootViewController:firstTab]; [firstTab release]; secondTab = // EDITED FOR SPACE thirdTab = // EDITED FOR SPACE tabBarController = [[UITabBarController alloc] init]; tabBarController.viewControllers = [NSArray arrayWithObjects:firstNavigationController, secondNavigationController, thirdNavigationController, nil]; [window addSubview:tabBarController.view]; [firstNavigationController release]; [secondNavigationController release]; [thirdNavigationController release]; [self logout]; [window makeKeyAndVisible]; Here is where the loginView.xib loads automatically: - (void)logout { loginViewController = [[LoginViewController alloc] initWithNibName:@"LoginView" bundle:nil]; UINavigationController *loginNavigationController = [[UINavigationController alloc] initWithRootViewController:loginViewController]; [loginViewController release]; [tabBarController presentModalViewController:loginNavigationController animated:YES]; [loginNavigationController release]; } I want to replace the above autoload with a test similar to below (that works) using IF-ELSE - (void)logout { if ([usernameLabel.text length] == 0 || [passwordLabel.text length] == 0) { loginViewController = [[LoginViewController alloc] initWithNibName:@"LoginView" bundle:nil]; UINavigationController *loginNavigationController = [[UINavigationController alloc] initWithRootViewController:loginViewController]; [loginViewController release]; [tabBarController presentModalViewController:loginNavigationController animated:YES]; [loginNavigationController release]; }else { [window addSubview:tabBarController.view];} Thanks in advance, I'm totally lost on this.

  • ai: Determining what tests to run to get most useful data

    - by Sai Emrys
    This is for http://cssfingerprint.com I have a system (see about page on site for details) where: I need to output a ranked list, with confidences, of categories that match a particular feature vector the binary feature vectors are a list of site IDs & whether this session detected a hit feature vectors are, for a given categorization, somewhat noisy (sites will decay out of history, and people will visit sites they don't normally visit) categories are a large, non-closed set (user IDs) my total feature space is approximately 50 million items (URLs) for any given test, I can only query approx. 0.2% of that space I can only make the decision of what to query, based on results so far, ~10-30 times, and must do so in <~100ms (though I can take much longer to do post-processing, relevant aggregation, etc) getting the AI's probability ranking of categories based on results so far is mildly expensive; ideally the decision will depend mostly on a few cheap sql queries I have training data that can say authoritatively that any two feature vectors are the same category but not that they are different (people sometimes forget their codes and use new ones, thereby making a new user id) I need an algorithm to determine what features (sites) are most likely to have a high ROI to query (i.e. to better discriminate between plausible-so-far categories [users], and to increase certainty that it's any given one). This needs to take into balance exploitation (test based on prior test data) and exploration (test stuff that's not been tested enough to find out how it performs). There's another question that deals with a priori ranking; this one is specifically about a posteriori ranking based on results gathered so far. Right now, I have little enough data that I can just always test everything that anyone else has ever gotten a hit for, but eventually that won't be the case, at which point this problem will need to be solved. I imagine that this is a fairly standard problem in AI - having a cheap heuristic for what expensive queries to make - but it wasn't covered in my AI class, so I don't actually know whether there's a standard answer. So, relevant reading that's not too math-heavy would be helpful, as well as suggestions for particular algorithms. What's a good way to approach this problem?

  • How to mmap the stack for the clone() system call on linux?

    - by Joseph Garvin
    The clone() system call on Linux takes a parameter pointing to the stack for the new created thread to use. The obvious way to do this is to simply malloc some space and pass that, but then you have to be sure you've malloc'd as much stack space as that thread will ever use (hard to predict). I remembered that when using pthreads I didn't have to do this, so I was curious what it did instead. I came across this site which explains, "The best solution, used by the Linux pthreads implementation, is to use mmap to allocate memory, with flags specifying a region of memory which is allocated as it is used. This way, memory is allocated for the stack as it is needed, and a segmentation violation will occur if the system is unable to allocate additional memory." The only context I've ever heard mmap used in is for mapping files into memory, and indeed reading the mmap man page it takes a file descriptor. How can this be used for allocating a stack of dynamic length to give to clone()? Is that site just crazy? ;) In either case, doesn't the kernel need to know how to find a free bunch of memory for a new stack anyway, since that's something it has to do all the time as the user launches new processes? Why does a stack pointer even need to be specified in the first place if the kernel can already figure this out?

  • Generics with constraints hierarchy

    - by devoured elysium
    I am currently facing a very disturbing problem: interface IStateSpace<Position, Value> where Position : IPosition // <-- Problem starts here where Value : IValue // <-- and here as I don't { // know how to get away this // circular dependency! // Notice how I should be // defining generics parameters // here but I can't! Value GetStateAt(Position position); void SetStateAt(Position position, State state); } As you'll down here, both IPosition, IValue and IState depend on each other. How am I supposed to get away with this? I can't think of any other design that will circumvent this circular dependency and still describes exactly what I want to do! interface IState<StateSpace, Value> where StateSpace : IStateSpace where Value : IValue { StateSpace StateSpace { get; }; Value Value { get; set; } } interface IPosition { } interface IValue<State> where State : IState { State State { get; } } Basically I have a state space IStateSpace that has states IState inside. Their position in the state space is given by an IPosition. Each state then has one (or more) values IValue. I am simplifying the hierarchy, as it's a bit more complex than described. The idea of having this hierarchy defined with generics is to allow for different implementations of the same concepts (an IStateSpace will be implemented both as a matrix as an graph, etc). Would can I get away with this? How do you generally solve this kind of problems? Which kind of designs are used in these cases? Thanks

  • How to speed up marching cubes?

    - by Dan Vinton
    I'm using this marching cube algorithm to draw 3D isosurfaces (ported into C#, outputting MeshGeomtry3Ds, but otherwise the same). The resulting surfaces look great, but are taking a long time to calculate. Are there any ways to speed up marching cubes? The most obvious one is to simply reduce the spatial sampling rate, but this reduces the quality of the resulting mesh. I'd like to avoid this. I'm considering a two-pass system, where the first pass samples space much more coarsely, eliminating volumes where the field strength is well below my isolevel. Is this wise? What are the pitfalls? Edit: the code has been profiled, and the bulk of CPU time is split between the marching cubes routine itself and the field strength calculation for each grid cell corner. The field calculations are beyond my control, so speeding up the cubes routine is my only option... I'm still drawn to the idea of trying to eliminate dead space, since this would reduce the number of calls to both systems considerably.

  • An implementation of Sharir's or Aurenhammer's deterministic algorithm for calculating the intersect

    - by RGrey
    The problem of finding the intersection/union of 'N' discs/circles on a flat plane was first proposed by M. I. Shamos in his 1978 thesis: Shamos, M. I. “Computational Geometry” Ph.D. thesis, Yale Univ., New Haven, CT 1978. Since then, in 1985, Micha Sharir presented an O(n log2n) time and O(n) space deterministic algorithm for the disc intersection/union problem (based on modified Voronoi diagrams): Sharir, M. Intersection and closest-pair problems for a set of planar discs. SIAM .J Comput. 14 (1985), pp. 448-468. In 1988, Franz Aurenhammer presented a more efficient O(n log n) time and O(n) space algorithm for circle intersection/union using power diagrams (generalizations of Voronoi diagrams): Aurenhammer, F. Improved algorithms for discs and balls using power diagrams. Journal of Algorithms 9 (1985), pp. 151-161. Earlier in 1983, Paul G. Spirakis also presented an O(n^2) time deterministic algorithm, and an O(n) probabilistic algorithm: Spirakis, P.G. Very Fast Algorithms for the Area of the Union of Many Circles. Rep. 98, Dept. Comput. Sci., Courant Institute, New York University, 1983. I've been searching for any implementations of the algorithms above, focusing on computational geometry packages, and I haven't found anything yet. As neither appear trivial to put into practice, it would be really neat if someone could point me in the right direction!
