  • How do I Extend Blogengine.Net to collect statistics of visitors?

    - by Stefan
    I love BlogEngine. But from what I can se it does not collect the standard information about the visitors I would like to see (referrer, browser-type and so on). When I log in as Admin I have a menu item named "Referrer". I can choose a weekday and then I'll be presented with 1 or 2 rows with "google.com 4 hits, "itmaskinen.se 6 hits" and so on, But that's not what I want to se, I want to se where my visitors come from, country, IP if possible, how many visitors and so on. If someone of you are familiar with Blogengine.Net and can point me in the right direction to where I would put my own log-code or if you know any visitor-statistic-extension that can do it for me, I would be really happy to know. I prefer an extension, because if I make changes myself to BlogEngine it may break later updates I install. Blogengine.Net is a blog software made in .Net found here: http://www.dotnetblogengine.net/ And yes, I prefer to take this question here rather then in the Blogengine.Net forum, you know why. ;) (Anyone, feel free to edit my (bad) english in this post and after that delete this sentence)

  • iPhone: change height of UITableViewCell coming from a NIB

    - by Stefan Klumpp
    I have a UITableView of custom UITableViewCells which looks like this: [ CELL 0 [ description ] [ dynamic content type 1 ] [ dynamic content type 2 ] [ dynamic content type 3 ] ] [ CELL 1 [ description ] [ dynamic content type 1 ] [ dynamic content type 3 ] ] [ CELL 2 [ description ] [ dynamic content type 2 ] ] [ ... and so on ... ] Since the [description] part is already pretty complex I decided to use Interface Builder to design it and at add the [dynamic content] in the cellForRowAtIndexPath programmatically with [cell addSubview:...]. My problem is now, that I set a default height for my custom UITableViewCell in Interface Builder, but when I add my [dynamic content] (which might range between 0..3) I have different cells with different heights. One thing is of course to calculate the total height and change the return value in heightForRowAtIndexPath, but how do I change the height value of my actual cell (which was loaded from a nib file with a fixed height)?

  • Estimate serialization size of objects?

    - by Stefan K.
    In my thesis, I woud like to enhance messaging in a cluster. It's important to log runtime information about how big a message is (should I prefer processing local or remote). I could just find frameoworks about estimating the object memory size based on java instrumentation. I've tested classmexer, which didn't come close to the serialization size and sourceforge SizeOf. In a small testcase, SizeOf was around 10% wrong and 10x faster than serialization. (Still transient breaks the estimation completely and since e.g. ArrayList is transient but is serialized as an Array, it's not easy to patch SizeOf. But I could live with that) On the other hand, 10x faster with 10% error doesn't seem very good. Any ideas how I could do better?

  • How do I remove sensitive files from git's history

    - by Stefan Liebenberg
    I would like to put a git project ( Rails app ) on github, but it contains certian files with sensitive data ( usernames and passwords, like /config/deploy.rb for capistrano ). I know I can add these filenames to .gitignore, but this would not remove the their history within git. I also don't want to start over again by deleting the /.git directory. Is there a way to remove all traces of a particular file in your git history?

  • iPhone: fast hash function for storing web images (url) as files (hashed filenames)

    - by Stefan Klumpp
    What is a fast hash function available for the iPhone to hash web urls (images)? I'd like to store the cached web image as a file with a hash as the filename, because I suppose the raw web url could contain strange characters that could cause problems on the file system. The hash function doesn't need to be cryptographic, but it definitely needs to be fast. Example: Input: http://www.calumetphoto.com/files/iccprofiles/icc-test-image.jpg Output: 3573ed9c4d3a5b093355b2d8a1468509 This was done by using MD5(), but since I don't know much about that topic I don't know if it is overkill (- slow).

  • How to write a Custom DesignerSerializer for an class used by a Activity (WF)

    - by Stefan Steinegger
    I have a type which is used in a WF activity. It should be serialized. It doesn't work out of the box, most probably because of the private setters in that type. I'm not sure if this is the correct way, but I tried to write my own serializer and declared it on my class. [DesignerSerializer( typeof(FooDesignerSerializer), // my custom serializer typeof(WorkflowMarkupSerializer))] public class Foo { public Foo(int value, string name { // ... } public int Value { get; private set; } public string Name { get; private set; } } Is this the easiest way to get it serialized? How do I write this serializer? That's what I got so far: public class FooDesignerSerializer : WorkflowMarkupSerializer { protected override string SerializeToString( WorkflowMarkupSerializationManager serializationManager, object value) { // how to create a valid / XOML-like string? } }

  • WPF: RadialGradientBrush without gradient?

    - by stefan.at.wpf
    Hello, I want to draw some circles in another circle like this: Is there a way to tell a RadialGradientBrush not to use gradients but just fixed colors, so I can achieve this? Thanks for any hint! (I guess this could be easily done using a DrawingBrush, I'm just wondering whether this could also be done using a RadialGradientBrush)

  • How do I detect the OpenJDK in my applet (System Properties)?

    - by Stefan Kendall
    How can I determine if my client is running OpenJDK with a web plugin? I've tried java.version and the rest of the properties listed here. Running java -version from the terminal works fine, but if I went this route, java would have to be on the user's path, which I don't know if I can trust entirely. Is there any other way to see the string given by java -version programmatically, without shelling out to the command line or terminal? Right now, when I run System.getProperties().getProperty("java.version"), I get Sun Microsystems Inc.!

  • What do the square brackets in LaTeX logs mean?

    - by stefan-majewsky
    I'm currently working on a parser that reads complete LaTeX logs. Most of the log format is, though weird, easy to figure out, but these square brackets are puzzling me. Here's an example from near the end of one of my logs: Overfull \hbox (10.88788pt too wide) in paragraph at lines 40--40 []$[]$ [] [102]) [103] Kapitel 14. (./Thermo-141-GrenzenFundamentalpostulat.tex [104 ]) (./Thermo-142-Mastergleichung.tex [105]) (./Thermo-143-HTheorem.tex [106pdfTeX warning (ext4): destination with the same identifier (name{equation.14.3.3}) ha s been already used, duplicate ignored Can anybody give me a hint what these square brackets mean? I can't see any structure in them. I have the suspicion that lines 2/3 above are some kind of ASCII art representing the box layout, though I know too less about badboxes to justify this or identify the meaning of the single characters. Then, the "[104" etc. seem to correspond to the page numbers, but I am still not seeing the reason why there is sometimes something inbetween the square brackets (like the pdfTeX warning above), and sometimes not.

  • iPhone: custom UITableViewCell with Interface Builder -> how to release cell objects?

    - by Stefan Klumpp
    The official documentation tells me I've to do these 3 things in order to manage the my memory for "nib objects" correctly. @property (nonatomic, retain) IBOutlet UIUserInterfaceElementClass *anOutlet; "You should then either synthesize the corresponding accessor methods, or implement them according to the declaration, and (in iPhone OS) release the corresponding variable in dealloc." - (void)viewDidUnload { self.anOutlet = nil; [super viewDidUnload]; } That makes sense for a normal view. However, how am I gonna do that for a UITableView with custom UITableViewCells loaded through a .nib-file? There the IBOutlets are in MyCustomCell.h (inherited from UITableViewCell), but that is not the place where I load the nib and apply it to the cell instances, because that happens in MyTableView.m So do I still release the IBOutlets in the dealloc of MyCustomCell.m or do I have to do something in MyTableView.m? Also MyCustomCell.m doesn't have a - (void)viewDidUnload {} where I can set my IBOutlets to nil, while my MyTableView.m does.

  • Sql Server Backup and move backup file: How to cope with file permissions?

    - by Stefan Steinegger
    With our product we have a simple backup tool for the sql server database. This tool should just make a full backup and restore to and from any folder. Of course, the user (usually an administrator) needs permission to write to the target folder. To avoid the problem of not being able to perform a backup to a network drive, I write the backup to a temp file in the Sql Server backup directory. Then I move it to the target folder. This requires permission to delete the temporary file from the sql servers backup folder. Restore is the same in the other direction. This seemed to work fine until someone tested it on vista, where the user does not have write access to the backup folder by default. So there are many solutions to solve this, but none of them seemed to be really nice. One solution would be to find another folder for the temporary file. Both the sql server user as well as the administrator performing the backup need read and write permissions. Is there such a directory? Any other ideas? Thanks a lot.

  • commons-exec: Executing a program on the system PATH?

    - by Stefan Kendall
    I'm trying to execute a program (convert from ImageMagick, to be specific) whose parent folder exists on the path. Ergo, when I run convert from the command line, it runs the command. The following, however, fails: String command = "convert" CommandLine commandLine = CommandLine.parse(command); commandLine.addArgument(...) ... int exitValue = executor.execute(commandLine); If I specify the full path of the convert executable (C:\Program files\...) then this code works. If I don't do this, I get an exception thrown with exit value 4. How do I get commons-exec to recognize the system path?

  • Using views as a data interface between modules in a database

    - by Stefan
    Hello, I am working on the database layout of a straighforward small database in Mysql. We want to modularize this system in order to have more flexiblity for different implementations we are going to make. Now, the idea was to have one module in the database (simple a group of tables with constraints between them) pass its data to the next module via views. In this way, changes in one module would not affect the other ones, as we can make sure in the view that the right data is present there at any time, although the underlying structure of tables might be different. The structure of the App handling the database would likewise be modularized. Is this something that is sometimes done? On a technical side, as I understand views can't have primary keys - how would I then adress such a view? What other issues should be considered?

  • initialising a 2-dim Array in Scala

    - by Stefan W.
    (Scala 2.7.7:) I don't get used to 2d-Arrays. Arrays are mutable, but how do I specify a 2d-Array which is - let's say of size 3x4. The dimension (2D) is fixed, but the size per dimension shall be initializable. I tried this: class Field (val rows: Int, val cols: Int, sc: java.util.Scanner) { var field = new Array [Char](rows)(cols) for (r <- (1 to rows)) { val line = sc.nextLine () val spl = line.split (" ") field (r) = spl.map (_.charAt (0)) } def put (val rows: Int, val cols: Int, c: Char) = todo () } I get this error: :11: error: value update is not a member of Char field (r) = spl.map (_.charAt (0)) If it would be Java, it would be much more code, but I would know how to do it, so I show what I mean: public class Field { private char[][] field; public Field (int rows, int cols, java.util.Scanner sc) { field = new char [rows][cols]; for (int r = 0; r < rows; ++r) { String line = sc.nextLine (); String[] spl = line.split (" "); for (int c = 0; c < cols; ++c) field [r][c] = spl[c].charAt (0); } } public static void main (String args[]) { new Field (3, 4, new java.util.Scanner ("fraese.fld")); } } and fraese.fld would look, for example, like that: M M M M . M I get some steps wide with val field = new Array Array [Char] but how would I then implement 'put'? Or is there a better way to implement the 2D-Array. Yes, I could use a one-dim-Array, and work with put (y, x, c) = field (y * width + x) = c but I would prefer a notation which looks more 2d-ish.

  • Executing php with crontab

    - by Stefan Konno
    Hi everyone. I'm trying to run a php-script on a scheduled basis. So I'd thought crontab was a good idea. The server I'm using is on Linux which I'm not that familiar with. So the problem I'm having is, I don't know how make the script executable from php. I need to reference the script, or put it into a folder that can run php from the command line. So I don't know what path to give my crontab, for example: 5 * * * * var/www/some/path/script.php I found some vague information about this php executable being found in /usr/bin/php But I can't find any php file in there, maybe I don't have it installed? My php5 and apache installation is in: /etc/php5 So my question becomes, is there anyway to execute a php-script with crontab in any other folder, or do I just lack the php executable in usr/bin/php?

  • Handing over FaceBook SessionKey from iPhone to PHP

    - by Stefan Mayr
    Hi! Users authenticate normally on my iPhone app, and the permission for publish_stream is requested correctly. When the user want to post something on his wall, the text is transmitted to my backend and the backend posts it (with the transmitted session key) to the users facebook wall. The first post is always possible but at the second, the response is: "The user hasn't authorized the application to perform this action" But I was already able to post some seconds ago. What is wrong? Best Steve

  • Unit tests - The benefit from unit tests with contract changes?

    - by Stefan Hendriks
    Recently I had an interesting discussion with a colleague about unit tests. We where discussing when maintaining unit tests became less productive, when your contracts change. Perhaps anyone can enlight me how to approach this problem. Let me elaborate: So lets say there is a class which does some nifty calculations. The contract says that it should calculate a number, or it returns -1 when it fails for some reason. I have contract tests who test that. And in all my other tests I stub this nifty calculator thingy. So now I change the contract, whenever it cannot calculate it will throw a CannotCalculateException. My contract tests will fail, and I will fix them accordingly. But, all my mocked/stubbed objects will still use the old contract rules. These tests will succeed, while they should not! The question that rises, is that with this faith in unit testing, how much faith can be placed in such changes... The unit tests succeed, but bugs will occur when testing the application. The tests using this calculator will need to be fixed, which costs time and may even be stubbed/mocked a lot of times... How do you think about this case? I never thought about it thourougly. In my opinion, these changes to unit tests would be acceptable. If I do not use unit tests, I would also see such bugs arise within test phase (by testers). Yet I am not confident enough to point out what will cost more time (or less). Any thoughts?
