  • Testing a wide variety of computers with a small company

    - by Tom the Junglist
    Hello everyone, I work for a small dotcom which will soon be launching a reasonably-complicated Windows program. We have uncovered a number of "WTF?" type scenarios that have turned up as the program has been passed around to the various not-technical-types that we've been unable to replicate. One of the biggest problems we're facing is that of testing: there are a total of three programmers -- only one working on this particular project, me -- no testers, and a handful of assorted other staff (sales, etc). We are also geographically isolated. The "testing lab" consists of a handful of VMWare and VPC images running sort-of fresh installs of Windows XP and Vista, which runs on my personal computer. The non-technical types try to be helpful when problems arise, we have trained them on how to most effectively report problems, and the software itself sports a wide array of diagnostic features, but since they aren't computer nerds like us their reporting is only so useful, and arranging remote control sessions to dig into the guts of their computers is time-consuming. I am looking for resources that allow us to amplify our testing abilities without having to put together an actual lab and hire beta testers. My boss mentioned rental VPS services and asked me to look in to them, however they are still largely very much self-service and I was wondering if there were any better ways. How have you, or any other companies in a similar situation handled this sort of thing? EDIT: According to the lingo, our goal here is to expand our systems testing capacity via an elastic computing platform such as Amazon EC2. At this point I am not sure suggestions of beefing up our unit/integration testing are going to help very much as we are consistently hitting walls at the systems testing phase. Has anyone attempted to do this kind of software testing on a cloud-type service like EC2? Tom

  • Reuse Client java Socket in a Java Server

  • kohana project structure

    - by user176217
    Hello Guys. I'm investigating using Kohana for my next project. The site will consist of user registration (and hence user profiles) where users will have certain privileges. The site will also have an admin section where administrators can go to say block a user or delete a post or look at usage statistics for example. A good comparison site would be a multi-user blog, where each blogger depending on her/his permissions can post/edit/delete blogs...just as an example. Firstly, I'm not sure about how to set up the controller/view structure in order to separate the admin section from the front facing site. I'm using Kohana 3, so I was thinking of a controller structure like so: application/classes/controller/front (front facing)...and application/classes/controller/admin (for administrative section). Or I notice you may be able to use the Route class to set up routes, so I could set up an "admin" route. for example: www.example.com/admin will lead to the admin logon screen. www.example.com --- front controller. As well, can I somehow separate the "Admin" views and controllers from the "front facing" views and controllers like divide them up based on folder structure? Any help is very much appreciated. Thank you.

  • SQL Server Multi-statement UDF - way to store data temporarily required

    - by Kharlos Dominguez
    Hello, I have a relatively complex query, with several self joins, which works on a rather large table. For that query to perform faster, I thus need to only work with a subset of the data. Said subset of data can range between 12 000 and 120 000 rows depending on the parameters passed. More details can be found here: http://stackoverflow.com/questions/3054843/sql-server-cte-referred-in-self-joins-slow As you can see, I was using a CTE to return the data subset before, which caused some performance problems as SQL Server was re-running the Select statement in the CTE for every join instead of simply being run once and reusing its data set. The alternative, using temporary tables worked much faster (while testing the query in a separate window outside the UDF body). However, when I tried to implement this in a multi-statement UDF, I was harshly reminded by SQL Server that multi-statement UDFs do not support temporary tables for some reason... UDFs do allow table variables however, so I tried that, but the performance is absolutely horrible as it takes 1m40 for my query to complete whereas the the CTE version only took 40minutes. I believe the table variables is slow for reasons listed in this thread: http://stackoverflow.com/questions/1643687/table-variable-poor-performance-on-insert-in-sql-server-stored-procedure Temporary table version takes around 1 seconds, but I can't make it into a function due to the SQL Server restrictions, and I have to return a table back to the caller. Considering that CTE and table variables are both too slow, and that temporary tables are rejected in UDFs, What are my options in order for my UDF to perform quickly? Thanks a lot in advance.

  • future-proofing java version check in ant script

    - by carneades
    The script provided here gave a great way to check if Ant is using Java 6. <?xml version="1.0" encoding="UTF-8"?> <project name="project" default="default"> <target name="default" depends="javaCheck" if="isJava6"> <echo message="Hello, World!" /> </target> <target name="javaCheck"> <echo message="ant.java.version=${ant.java.version}" /> <condition property="isJava6"> <equals arg1="${ant.java.version}" arg2="1.6" /> </condition> </target> </project> However, I have good reason to think the next person holding my position may not be a Java programmer and I want to make sure the builds don't fail because of Java 7. Is there any way to pick apart a String or otherwise ask for Java 6 or higher?

  • ASP.NET lock thread method

    - by Peter
    Hello, I'm developing an ASP.NET forms webapplication using C#. I have a method which creates a new Order for a customer. It looks similar to this; private string CreateOrder(string userName) { // Fetch current order Order order = FetchOrder(userName); if (order.OrderId == 0) { // Has no order yet, create a new one order.OrderNumber = Utility.GenerateOrderNumber(); order.Save(); } return order; } The problem here is, it is possible that 1 customer in two requests (threads) could cause this method to be called twice while another thread is also inside this method. This can cause two orders to be created. How can I properly lock this method, so it can only be executed by one thread at a time per customer? I tried; Mutex mutex = null; private string CreateOrder(string userName) { if (mutex == null) { mutex = new Mutex(true, userName); } mutex.WaitOne(); // Code from above mutex.ReleaseMutex(); mutex = null; return order; } This works, but on some occasions it hangs on WaitOne and I don't know why. Is there an error, or should I use another method to lock? Thanks

  • Cursor while loop returning every value but the last

    - by LordSnoutimus
    Hello, I am using a while loop to iterate through a cursor and then outputing the longitude and latitude values of every point within the database. For some reason it is not returning the last (or first depending on if I use Cursor.MoveToLast) set of longitude and latitude values in the cursor. Here is my code: public void loadTrack() { SQLiteDatabase db1 = waypoints.getWritableDatabase(); Cursor trackCursor = db1.query(TABLE_NAME, FROM, "trackidfk=1", null, null, null,ORDER_BY); trackCursor.moveToFirst(); while (trackCursor.moveToNext()) { Double lat = trackCursor.getDouble(2); Double lon = trackCursor.getDouble(1); //overlay.addGeoPoint( new GeoPoint( (int)(lat*1E6), (int)(lon*1E6))); System.out.println(lon); System.out.println(lat); } } From this I am getting: 04-02 15:39:07.416: INFO/System.out(10551): 3.0 04-02 15:39:07.416: INFO/System.out(10551): 5.0 04-02 15:39:07.416: INFO/System.out(10551): 4.0 04-02 15:39:07.416: INFO/System.out(10551): 5.0 04-02 15:39:07.416: INFO/System.out(10551): 5.0 04-02 15:39:07.416: INFO/System.out(10551): 5.0 04-02 15:39:07.416: INFO/System.out(10551): 4.0 04-02 15:39:07.416: INFO/System.out(10551): 4.0 04-02 15:39:07.416: INFO/System.out(10551): 3.0 04-02 15:39:07.416: INFO/System.out(10551): 3.0 04-02 15:39:07.416: INFO/System.out(10551): 2.0 04-02 15:39:07.416: INFO/System.out(10551): 2.0 04-02 15:39:07.493: INFO/System.out(10551): 1.0 04-02 15:39:07.493: INFO/System.out(10551): 1.0 7 Sets of values, where I should be getting 8 sets.

  • Outputing value of TrueClass / FalseClass to integer or string/

    - by Nick Gorbikoff
    Hello. I'm trying to figure out if there is an easy way to do the following short of adding to_i method to TrueClass/FalseClass. Here is a dilemma: I have a boolean field in my rails app - that is obviously stored as Tinyint in mysql. However - I need to generate xml based of the data in mysql and send it to customer - there SOAP service requires the field in question to have 0 or 1 as the value of this field. So at the time of the xml generation I need to convert my False to 0 and my True to 1 ( which is how they are stored in the DB). Since True & False lack to_i method I could write some if statement that generate either 1 or 0 depending on true/false state. However I have about 10 of these indicators and creating and if/else for each is not very DRY. So what you recommend I do? Or I could add a to_i method to the True / False class. But I'm not sure where should I scope it in my rails app? Just inside this particular model or somewhere else?

  • Table borders don't display properly when converted from HTML page into MS Word 2003

    - by Daria
    Hello everyone, I've got a bit of a complicated set up. I specialise in XSLT which I write for 3rd party system. All CSS looks fine in the browser. Now that system provides a button that converts my generated HTML into MS Word 2003. However, table borders don't convert as they appear in a Browser. There are lots of tables and they have different borders setup. For example there is one that uses only outside border and no borders inside it. When converting to MS Word, a table appears with ALL the borders in between cells. Which I don't want. I've tried search the Internet, but didn't come across anything useful. Maybe there are tips or tricks on how to set up tables borders so it's understood properly by MS Word. The third party said the following: "The system just passes the HTML created through the converter it finds in the installed version of Word". I would really appreciate any tips and help! Dasha

  • Email Tracking - GMail

    - by Abs
    Hello all, I am creating my own email tracking system for email marketing tracking. I have been able to determine each persons email client they are using by using the http referrer but for some reason GMAIL does not send a HTTP_REFERRER at all! So I am trying to find another way of identifying when gmail requests a transparent image from my server. I get the following headers print_r($_SERVER);: DOCUMENT_ROOT = /usr/local/apache/htdocs GATEWAY_INTERFACE = CGI/1.1 HTTP_ACCEPT = */* HTTP_ACCEPT_CHARSET = ISO-8859-1,utf-8;q=0.7,*;q=0.3 HTTP_ACCEPT_ENCODING = gzip,deflate,sdch HTTP_ACCEPT_LANGUAGE = en-GB,en-US;q=0.8,en;q=0.6 HTTP_CONNECTION = keep-alive HTTP_COOKIE = __utmz=156230011.1290976484.1.1.utmcsr=(direct)|utmccn=(direct)|utmcmd=(none); __utma=156230011.422791272.1290976484.1293034866.1293050468.7 HTTP_HOST = xx.xxx.xx.xxx HTTP_USER_AGENT = Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US) AppleWebKit/534.10 (KHTML, like Gecko) Chrome/8.0.552.237 Safari/534.10 PATH = /bin:/usr/bin QUERY_STRING = i=MTA= REDIRECT_STATUS = 200 REMOTE_ADDR = xx.xxx.xx.xxx REMOTE_PORT = 61296 REQUEST_METHOD = GET Is there anything of use in that list? Or is there something else I can do to actually get the http referrer, if not how are other ESPs managing to find whether gmail was used to view an email? Btw, I appreciate it if we can hold back on whether this is ethical or not as many ESPs do this already, I just don't want to pay for their service and I want to do it internally. Thanks all for any implementation advice. Update Just thought I would update this question and make it clearer in light of the bounty. I would like to find out when a user opens my email when sent to a GMail inbox. Assume, I have the usual transparent image tracking and the user does not block images. I would like to do this with the single request and the header details I get when the transparent image is requested.

  • Behavior of retained property while holder is retained

    - by Aurélien Vallée
    Hello everyone, I am a beginner ObjectiveC programmer, coming from the C++ world. I find it very difficult to understand the memory management offered by NSObject :/ Say I have the following class: @interface User : NSObject { NSString* name; } @property (nonatomic,retain) NSString* name; - (id) initWithName: (NSString*) theName; - (void) release; @end @implementation User @synthesize name - (id) initWithName: (NSString*) theName { if ( self = [super init] ) { [self setName:theName]; } return self; } - (void) release { [name release]; [super release]; } @end No considering the following code, I can't understand the retain count results: NSString* name = [[NSString alloc] initWithCString:/*C string from sqlite3*/]; // (1) name retainCount = 1 User* user = [[User alloc] initWithName:name]; // (2) name retainCount = 2 [whateverMutableArray addObject:user]; // (3) name retainCount = 2 [user release]; // (4) name retainCount = 1 [name release]; // (5) name retainCount = 0 At (4), the retain count of name decreased from 2 to 1. But that's not correct, there is still the instance of user inside the array that points to name ! The retain count of a variable should only decrease when the retain count of a referring variable is 0, that is, when it is dealloced, not released.

  • Getting jQuery to return an ajax object

    - by japancheese
    Hello, The question title is a bit strange because I'm not exactly sure how to phrase the problem. The issue is that I have many links to which I want to bind a click event with an ajax call, and I'm just looking to refactor some duplicate code into a single area. The links I'm trying to bind an ajax call only have one thing that differentiates them, and that's an id from a previously declared object. So I have lots of code that looks like this: $("a.link").bind('click', function() { id = obj.id; $.ajax({ url: "/set/" + id, dataType: 'json', type: "POST" }) }); I was trying to refactor it into something like this: $("a.link").bind('click', ajax_link(obj.id)); function ajax_link(id) { $.ajax({ url: "/set/" + id, dataType: 'json', type: "POST" }) }); However, as you can imagine, this just actually makes the ajax call when the element is binded with the click event. Is there an easy way to refactor this code so I can extract out the common ajax code into its own function, and hopefully reduce the number of lines of jQuery in my current script?

ClassB has again a member, maybe an int: ClassB { public int MemberOfB { get; set; } } ClassA { private ClassB _theB; public ClassB MemberOfA { get {return _theB;} set { _theB = value; // Need to do something here... } } } When I have a Databinding in XAML like this: <TextBox Text="{Binding Path=MemberOfA.MemberOfB}"/> Where the Datacontext of the Textbox is an object of type ClassA. As you can see, i need to do some computations in the setter of MemberOfA in ClassA. But with the databinding above, this setter is of course never called, because it binds to the member of ClassB. So, how can i get to be informed if the MemberOfA changes (when I Type something into the Textbox)? Are there any best practices? (Didn't check the code in Visual Studio, so there may be some syntax errors). Thanks, Walter

  • XSL: List divided into columns.

    - by kalininew
    Hello, help me please. There is a list of nodes. <list> <item>1</item> <item>2</item> <item>3</item> <item>4</item> <item>5</item> <item>6</item> <item>7</item> and so on... </list> Need to divide the list of "n" (arbitrary number) equal parts. If the number of nodes is not divided equally, then let the last set of nodes will contain the remainder of the division. For example, if the input list contains 33 elements and the output should have 4 parts with uniformly distributed elements. At the exit to get 3 parts to 9 of elements and one part with 6 elements in the sum of 33.

  • SQL with Regular Expressions vs Indexes with Logical Merging Functions

    - by geeko
    Hello Lads, I am trying to develop a complex textual search engine. I have thousands of textual pages from many books. I need to search pages that contain specified complex logical criterias. These criterias can contain virtually any compination of the following: A: Full words. B: Word roots (semilar to stems; i.e. all words with certain key letters). C: Word templates (in some languages are filled in certain templates to form various part of speech such as adjactives, past/present verbs...). D: Logical connectives: AND/OR/XOR/NOT/IF/IFF and parentheses to state priorities. Now, would it be faster to have the pages' full text in database (not indexed) and search though them all using SQL and Regular Expressions ? Or would it be better to construct indexes of word/root/template-page-location tuples. Hence, we can boost searching for individual words/roots/templates. However, it gets tricky as we interdouce logical connectives into our query. I thought of doing the following steps in such cases: 1: Seperately search for each individual words/roots/templates in the specified query. 2: On priority bases, we merge two result lists (from step 1) at a time depedning on the logical connective For example, if we are searching for "he AND (is OR was)": 1: We shall search for "he", "is" and "was" seperately and get result lists for each word. 2: Merge the result lists of "is" and "was" using the merging function OR-MERGE 3: Merge the merged result list from the OR-MERGE function with the one of "he" using the merging function AND-MERGE The result of step 3 is then returned as the result of the specified query. What do you think gurues ? Which is faster ? Any better ideas ? Thank you all in advance.

  • PDO empy result from SELECT when using AND

    - by Jurgen
    Hello, I've come upon a rather interesting thing, which I can't seem to figure out myself. Everytime when executing a SQL statement which contains a '... AND ...' the result is empty. Example: echo('I have a user: ' . $email . $wachtwoord . '<br>'); $dbh = new PDO($dsn, $user, $password); $sql = 'SELECT * FROM user WHERE email = :email AND wachtwoord= :wachtwoord'; $stmt = $dbh->prepare($sql); $stmt->bindParam(:email,$email,PDO::PARAM_STR); $stmt->bindParam(:wachtwoord,$wachtwoord,PDO::PARAM_STR); $stmt->execute(); while($row = $stmt->fetchObject()) { echo($row-email . ',' . $row-wachtwoord); $user[] = array( 'email' = $row-email, 'wachtwoord' = $row-wachtwoord ); } The first echo displays the correct values, however the line with echo($row->email . ',' . $row->wachtwoord); is never reached. A few things I want to add: 1) I am connected to the database since other queries work, only the ones where I add an 'AND' after my 'WHERE's fail. 2) Working with the while works perfectly with queries that do not contain '... AND ...' 3) Error reporting is on, PDO gives no exceptions on my query (or anything else) 4) Executing the query directly on the database does give what I want: SELECT * FROM user WHERE email = '[email protected]' AND wachtwoord = 'jurgen' I can stare at it all day long again (which I already did once, but I managed to work around the 'AND'), but maybe one of you can give me a helping hand. Thank you in advance. Jurgen

  • Get percentiles of data-set with group by month

    - by Cylindric
    Hello, I have a SQL table with a whole load of records that look like this: | Date | Score | + -----------+-------+ | 01/01/2010 | 4 | | 02/01/2010 | 6 | | 03/01/2010 | 10 | ... | 16/03/2010 | 2 | I'm plotting this on a chart, so I get a nice line across the graph indicating score-over-time. Lovely. Now, what I need to do is include the average score on the chart, so we can see how that changes over time, so I can simply add this to the mix: SELECT YEAR(SCOREDATE) 'Year', MONTH(SCOREDATE) 'Month', MIN(SCORE) MinScore, AVG(SCORE) AverageScore, MAX(SCORE) MaxScore FROM SCORES GROUP BY YEAR(SCOREDATE), MONTH(SCOREDATE) ORDER BY YEAR(SCOREDATE), MONTH(SCOREDATE) That's no problem so far. The problem is, how can I easily calculate the percentiles at each time-period? I'm not sure that's the correct phrase. What I need in total is: A line on the chart for the score (easy) A line on the chart for the average (easy) A line on the chart showing the band that 95% of the scores occupy (stumped) It's the third one that I don't get. I need to calculate the 5% percentile figures, which I can do singly: SELECT MAX(SubQ.SCORE) FROM (SELECT TOP 45 PERCENT SCORE FROM SCORES WHERE YEAR(SCOREDATE) = 2010 AND MONTH(SCOREDATE) = 1 ORDER BY SCORE ASC) AS SubQ SELECT MIN(SubQ.SCORE) FROM (SELECT TOP 45 PERCENT SCORE FROM SCORES WHERE YEAR(SCOREDATE) = 2010 AND MONTH(SCOREDATE) = 1 ORDER BY SCORE DESC) AS SubQ But I can't work out how to get a table of all the months. | Date | Average | 45% | 55% | + -----------+---------+-----+-----+ | 01/01/2010 | 13 | 11 | 15 | | 02/01/2010 | 10 | 8 | 12 | | 03/01/2010 | 5 | 4 | 10 | ... | 16/03/2010 | 7 | 7 | 9 | At the moment I'm going to have to load this lot up into my app, and calculate the figures myself. Or run a larger number of individual queries and collate the results.

  • TCP: Address already in use exception - possible causes for client port? NO PORT EXHAUSTION

    - by TomTom
    Hello, stupid problem. I get those from a client connecting to a server. Sadly, the setup is complicated making debugging complex - and we run out of options. The environment: *Client/Server system, both running on the same machine. The client is actually a service doing some database manipulation at specific times. * The cnonection comes from C# going through OleDb to an EasySoft JDBC driver to a custom written JDBC server that then hosts logic in C++. Yeah, compelx - but the third party supplier decided to expose the extension mechanisms for their server through a JDBC interface. Not a lot can be done here ;) The Symptom: At (ir)regular intervals we get a "Address already in use: connect" told from the JDBC driver. They seem to come from one particular service we run. Now, I did read all the stuff about port exhaustion. This is why we have a little tool running now that counts ports and their states every minute. Last time this happened, we had an astonishing 370 ports in use, with the count rising to about 900 AFTER the error. We aleady patched the registry (it is a windows machine) to allow more than the 5000 client ports standard, but even then, we are far far from that limit to start with. Which is why I am asking here. Ayneone an ide what ELSE could cause this? It is a Windows 2003 Server machine, 64 bit. The only other thing I can see that may cause it (but this functionality is supposedly disabled) is Symantec Endpoint Protection that is installed on the server - and being capable of actinc as a firewall, it could possibly intercept network traffic. I dont want to open a can of worms by pointing to Symantec prematurely (if pointing to Symantec can ever be seen as such). So, anyone an idea what else may be the cause? Thanks

  • Dynamically Resizing an Iframe

    - by regex
    Hello All, I can see that this question has been asked several times, but none of the proposed solutions seem to work for the site I am building, so I am reopening the thread. I am attempting to size an iframe based on the height of it's content. Both the page that contains the iframe and it's source page exist on the same domain. I have tried the proposed solutions in each of the following threads: Resize iframe height according to content height in it Resizing an iframe based on content I believe that the solutions above are not working because of when the reference to body.clientHeight is made, the browser has not actually determined the height of the document. Here is the code I am using: var ifmBlue = document.getElementById("ifmBlue"); ifmBlue.onload = resizeIframe; function resizeIframe() { var ifmBlue = document.getElementById("ifmBluePill"); var ifmDiv = ifmBlue.contentDocument.getElementById("main"); var height = ifmDiv.clientHeight; ifmBlue.style.height = (ifmBlue.contentDocument.body.scrollHeight || ifmBlue.contentDocument.body.offsetHeight || ifmBlue.contentDocument.body.parentNode.clientHeight || height || 500) + 5 + 'px'; } If I debug the script using fire debug, the client height of the iframe.contentDocument's main div is 0. Additionally, body.offsetHieght, & body.scrollHeight are 0. However, after the script is finished running, if I inspect the DOM of the HTML iframe element (using fire debug) I can see that the body's clientHeight is 456 and the inner div's clientHeight is 742. This leads me to believe that these values are not yet set when iframe.onload is fired. So, per one of the threads above, I moved the code into the body.onload event handler of the iframe's source page. This solution also did not work. Any help you can provide is much appreciated. Thanks, CJ

  • EOL Special Char not matching

    - by Aurélien Ribon
    Hello, I am trying to find every "a - b, c, d" pattern in an input string. The pattern I am using is the following : "^[ \t]*(\\w+)[ \t]*->[ \t]*(\\w+)((?:,[ \t]*\\w+)*)$" This pattern is a C# pattern, the "\t" refers to a tabulation (its a single escaped litteral, intepreted by the .NET String API), the "\w" refers to the well know regex litteral predefined class, double escaped to be interpreted as a "\w" by the .NET STring API, and then as a "WORD CLASS" by the .NET Regex API. The input is : a -> b b -> c c -> d The function is : private void ParseAndBuildGraph(String input) { MatchCollection mc = Regex.Matches(input, "^[ \t]*(\\w+)[ \t]*->[ \t]*(\\w+)((?:,[ \t]*\\w+)*)$", RegexOptions.Multiline); foreach (Match m in mc) { Debug.WriteLine(m.Value); } } The output is : c -> d Actually, there is a problem with the line ending "$" special char. If I insert a "\r" before "$", it works, but I thought "$" would match any line termination (with the Multiline option), especially a \r\n in a Windows environment. Is it not the case ?

  • How to transfer value from a DropDownList to a property of a serialized model object

    - by Richard77
    Hello, I'm testing some concepts in ASP.NET MVC multisteps (Style Wizards) with a small application which allow me to records organizations in a database. To make things easier, I've a class OrganizationFormModelView that contains an object of class Organization and a property called ParentOrgList of SelectList type. The only purpose of the selectList property is to be used by a DropDownList. I've also serialize OrganizationFormModelView to get the multisteps Wizard effect. In my first view (or first step), I use a dropdownlist helper to assign a value to one of the the Organization's property called ParentOrganization, which draws data from the ParentOrgList. ... <% = Html.DropDownList("Organization.ParentOrganization", Model.ParentOrgList)%> ... The first time the page loads, I'm able to make a choice. And, my choice is reflected in my object Model all along the wizard' steps(see Visual studio in debugging mode). But, when any time I'm redirected back to the first view (first step), I get the following error message: "The ViewData item with the key 'Organization.ParentOrganization' is of type 'System.String' but needs to be of type 'IEnumerable'." Thanks for helping
