• How do I get a single value from a stored proc using Nettiers

  - by Micah

  I have a really simple stored procedure that looks like this: CREATE PROCEDURE _Visitor_GetVisitorIDByVisitorGUID ( @VisitorGUID AS UNIQUEIDENTIFIER ) AS DECLARE @VisitorID AS bigint SELECT @VisitorID = VisitorID FROM dbo.Visitor WHERE VisitorGUID = @VisitorGUID --Here's what I've tried RETURN @VisitorID 'Returns an IDataReader SELECT @VisitorID 'Returns an IDataReader --I've also set it up wuth a single output --parameter, but that means I need to pass --the long in by ref and that's hideous to me I'm trying to get nettiers to generate a method with this signature: public long VisitorService.GetVisitorIDByVisitorGUID(GUID visitorGUID); Basically I want Nettiers to call ExecuteScalar instead of ExecuteReader. What am I doing wrong?

• Having problems getting a PHP regex to match.

  - by dqhendricks

  Here is my problem. It's probably a simple fix. I have a regex that I am using to replace a url BBCode. What I have right now that is not working looks like this. <?php $input_string = '[url=www.test.com]Test[url]'; $regex = '/\[url=(.+?)](.+?)\[\/url]/is'; $replacement_string = '<a href="$1">$2</a>'; echo preg_replace($regex, $replacement_string, $input_string); ?> This currently outputs the original $input_string, while I would like it to output the following. <a href="www.test.com">Test</a> What am I missing?

• Sequel Migration not running up?

  - by Sleepycat

  Having some trouble with the Migrations in Sequel and could use another set of eyes. I am running a migration that looks ok but no table is created. It is definitely connecting because I can see the schema_info table has been created. -M 0/1 changes the version as you would expect but still no table. The command: sequel -m . -M 1 ~/Desktop/dbtest/testdb.yml 001_testdb.rb: class TestDb < Sequel::Migration def up create_table( "terminals") do primary_key :id Integer :location_id Integer :merchant_id BigDecimal :terminal_id, :size=>[11, 0] String :reference, :size=>255 DateTime :created_at DateTime :updated_at String :image, :default=>"default.jpg", :size=>255 end end def down drop_table :terminals end end The output in Postgres: test_db=# \dt List of relations Schema | Name | Type | Owner --------+-------------+-------+---------- public | schema_info | table | postgres (1 row) test_db=# select * from schema_info; version --------- 1 (1 row)

• problem showing pictures stored outside web root folder

  - by David

  On a website users can upload pictures. For security reasons these are stored outside the webroot (public_html) folder. When I need to display the picture, I send the headers and have "readfile" read and output the picture data, like so: header("Pragma: public"); header("Expires: 0"); // set expiration time header("Cache-Control: must-revalidate, post-check=0, pre-check=0"); header('Content-type: image/jpg'); header('Content-Length: ' . $filesize); readfile($path_url . '/' . $photo); This works great, but the site is growing and this is starting to be a burden on the server. Question: is there a way to send the picture or picture data to the user, without the server first having to load the picture (obviously with the picture still being stored outside the webroot folder)? Thanks! David

• Convert Double to String without precision loss in javascript

  - by holger

  I would like to convert a floating point variable to a string without losing any precision. I.e. I would like the string to have the same information as my floating point variable contains, since I use the output for further processing (even if it means that the string will be very long and readable). To put this more clearly, I would like to have functions for cyclic conversion var dA = 323423.23423423e4; var sA = toString(dA); var dnA = toDouble(sA); and I would like dnA and dA to be equal Thanks PS: Sources on the internet usually talk about how to round strings but I have not found information on exact representation. Also I am not interested in Arbitrary Precision calculations, I just need double precision floating point arithmetic.

• Re-send POST request easily - what tools?

  - by Fabien

  I am looking for an easy way to re-send POST request to the server within the browser mainly for debug purposes. Say you have a XHR request which contains POST parameters that is to be send to the server. After having changed the script on the server side, you would like to resent the very same request for analyzing the output. What tool could help? I guess it is a browser's extension. I already tried extension Tamper Data for Firefox which does the job as you can "Replay in browser". But for my taste, it is not enough straight forward, as there are 3 - 4 clicks to get the result of the request. Unfortunately, curl would not be suitable for my needs as my application has a session's cookie.

• Zend Framework: Flash Messenger, add a message from the model

  - by Dan

  Any idea on how best to add a message to flash messenger from the model? As FlashMessenger is an action helper, this seems not to be possible, so the obvious solution is to create an internal message object in the model, and return that to the controller from where you can use addMessage(). But if you want to return something else as well, this falls down. Another idea is an additional session namespace for these internal messages, which is then merged in with the Flash Messenger namespace messages at output time? Anyone have any thoughts or experience on this? Cheers.

• Big Visible Charts

  - by Robert May

  An important part of Agile is the concept of transparency and visibility. In proper functioning teams, stakeholders can look at any team at any time in the iteration or release and see how that team is doing by simply looking at what we call Big Visible Charts. If you’ve done Scrum, you’ve seen these charts. However, interpreting these charts can often be an art form. There are several different charts that can be useful. In this newsletter, I’ll focus on the Iteration Burndown and Cumulative Flow charts. I’ve included a copy of the spreadsheet that I used to create the charts, and if you don’t have a tool that creates them for you, you can use this spreadsheet to do so. Our preferred tool for managing Scrum projects is Rally. Rally creates all of these charts for you, saving you quite a bit of time. The Iteration Burndown and Cumulative Flow Charts This is the main chart that teams use. Although less useful to stakeholders, this chart is critical to the team and provides quite a bit of information to the team about how their iteration is going. Most charts are a combination of the charts below, so you may need to combine aspects of each section to understand what is happening in your iterations. Ideal Ah, isn’t that a pretty picture? Unfortunately, it’s also very unrealistic. I’ve seen iterations that come close to ideal, but never that match perfectly. If your iteration matches perfectly, chances are, someone is playing with the numbers. Reality is just too difficult to have a burndown chart that matches this exactly. Late Planning Iteration started, but the team didn’t. You can tell this by the fact that the real number of estimated hours didn’t appear until day two. In the cumulative flow, you can also see that nothing was defined in Day one and two. You want to avoid situations like this. You’ll note that the team had to burn faster than is ideal to meet the iteration because of the late planning. This often results in long weeks and days. Testing Starved Determining whether or not testing is starved is difficult without the cumulative flow. The pattern in the burndown could be nothing more that developers not completing stories early enough or could be caused by stories being too big. With the cumulative flow, however, you see that only small bites are in progress and stories were completed early, but testing didn’t start testing until the end of the iteration, and didn’t complete testing all stories in the iteration. When this happens, question whether or not your testing resources are sufficient for your team and whether or not acceptance is adequately defined. No Testing With this one, both graphs show the same thing; the team needs testers and testing! Without testing, what was completed cannot be verified to make sure that it is acceptable to the business. If you find yourself in this situation, review your testing practices and acceptance testing process and make changes today. Late Development With this situation, both graphs tell a story. In the top graph, you can see that the hours failed to burn down as quickly as the team expected. This could be caused by the team not correctly estimating their hours or the team could have had illness or some other issue that affected them. Often, when teams are tackling something that is more unknown, they’ll run into technical barriers that cause the burn down to happen slower than expected. In the cumulative flow graph, you can see that not much was completed in the first few days. This could be because of illness or technical barriers or simply poor estimation. Testing was able to keep up with everything that was completed, however. No Tool Updating When you see graphs that look like this, you can be assured that it’s because the team is not updating the tool that generates the graphs. Review your policy for when they are to update. On the teams that I run, I require that each team member updates the tool at least once daily. You should also check to see how well the team is breaking down stories into tasks. If they’re creating few large tasks, graphs can look similar to this. As a general rule, I never allow tasks, other than Unit Testing and Uncertainty, to be greater than eight hours in duration. Scope Increase I always encourage team members to enter in however much time they think they have left on a task, even if that means increasing the total amount of time left to do. You get a much better and more realistic picture this way. Increasing time remaining could explain the burndown graph, but by looking at the cumulative flow graph, we can see that stories were added to the iteration and scope was increased. Since planning should consume all of the hours in the iteration, this is almost always a bad thing. If the scope change happened late in the iteration and the hours remaining were well below the ideal burn, then increasing scope is probably o.k., but estimation needs to get better. However, with the charts above, that’s clearly not what happened and the team was required to do extra work to make the iteration. If you find this happening, your product owner and ScrumMasters need training. The team also needs to learn to say no. Scope Decrease Scope decreases are just as bad as scope increases. Usually, graphs above show that the team did a poor job of estimating their stories and part way through had to reduce scope to change the iteration. This will happen once in a while, but if you find it’s a pattern on your team, you need to re-evaluate planning. Some teams are hopelessly optimistic. In those cases, I’ll introduce a task I call “Uncertainty.” With Uncertainty, the team estimates how many hours they might need if things don’t go well with the tasks they’ve defined. They try to estimate things that could go poorly and increase the time appropriately. Having an Uncertainty task allows them to have a low and high estimate. Uncertainty should not just be an arbitrary buffer. It must correlate to real uncertainty in the tasks that have been defined. Stories are too Big Often, we see graphs like the ones above. Note that the burndown looks fairly good, other than the chunky acceptance of stories. However, when you look at cumulative flow, you can see that at one point, everything is in progress. This is a bad thing. When you see graphs like this, you’re in one of two states. You may just have a very small team and can only handle one or two stories in your iteration. If you have more than one or two people, then the most likely problem is that your stories are far too big. To combat this, break large high hour stories into smaller pieces that can be completed independently and accepted independently. If you don’t, you’ll likely be requiring your testers to do heroic things to complete testing on the last day of the iteration and you’re much more likely to have the entire iteration fail, because of the limited amount of things that can be completed. Summary There are other charts that can be useful when doing scrum. If you don’t have any big visible charts, you really need to evaluate your process and change. These charts can provide the team a wealth of information and help you write better software. If you have any questions about charts that you’re seeing on your team, contact me with a screen capture of the charts and I’ll tell you what I’m seeing in those charts. I always want this information to be useful, so please let me know if you have other questions. Technorati Tags: Agile

• ASP: Extend control (ASCX) and access base markup file from subclass code

  - by Pathoschild

  Hello, I'm building form validation controls for our C# ASP application. The bulk of the work is handled by a BaseValidator control (subclassing System.Web.UI.UserControl), which also has the markup for the validation output. This is then extended by subcontrols like PasswordValidator, that provides the Validate method and any extra fields needed by that validator control. (The end goal is to have controls like <uc1:PasswordValidator ControlId="txtPassword" /> which we can plop into any form with minimum duplication.) However, PasswordValidator.ascx.cs cannot access the form elements defined in BaseValidator.ascx; the only way I've found to do so is to duplicate the markup in each subcontrol's *.ascx file. How can I extend BaseValidator.ascx.cs and access BaseValidator.ascx's markup in the subclass?

• Unable to boot Ubuntu 13.10 (nVidia GTX 770m and Intel HD 4600)

  - by Raziel Gonzalez

  Ever since I bought this laptop I've been trying to install Ubuntu on it. It came with W8 preinstalled. Up to this point, I've been able to boot in UEFI mode with a black screen. I can tell it's trying to use the nVidia card (there's a led on the computer, depending on the color you can tell which GPU is using) and if I press crtl+alt+F1 I can go to console mode. Taking this advantage I tried to install bumblebee and after a successful install the led that indicates which GPU is being used change, indicating that it switched to the Intel HD 4600 graphics. After the installation I tried to initiate the graphic interface (startx) with no success.

• Are there any serialization frameworks for java

  - by Grofit

  I know there is simple, which seems to be a decent enough XML serializer and i know there is Jaxb which seems to do the job as well. However im after something a bit more generic, so I could serialize my model to Xml, Json, Binary etc. So the models are just dumb objects that just get thrown into some sort of serialization factory and then the relevant output is spat out... I dont see any reason why you couldn't do this with reflection, so for a REALLY simple solution get the relevent public properties, cut off the get or set and make that the element name... i.e getPersonName() would become <PersonName>xxxx</PersonName> or PersonName:XXXXX

• eclipse xdebug session never completes

  - by Scott Szretter

  I am trying to get xdebug working with eclipse (3.5) / php (on xampp windows 7). I have verified xdebug is enabled in php - I have the fancy output and my phpinfo shows all the xdebug stuff. I have remote debug on, and typed in the lan ip address on my eclipse machine. When I tell eclipse to debug, it launches the browser and passes the debug URL parameters. That looks OK. However, in eclipse debug perspective it shows 'launching myproject' 57% 'waiting for xdebug session'. It sits there forever. I have turned off windows firewall on both machines. I tried turning implicit flush on. Any ideas?

• Data validate tools (ETL tools) for SQL server

  - by Stan

  I have some data in Excel and need to import into database. Is there any tool that can validate and maybe clean the data? Does Red Gate have such tool? The input will be Excel. Given table constraints, eg. CHECK, UNIQUE KEY, datetime format, NOT NULL. Desire output should be as least shows which lines are having problems, and then fix some trivial error automatically, like fill in default value for NULL columns, automatically correct datetime format. I know using Python can build such a script. But just wonder what's the popular way to do this. Thanks.

• Rotating text in postscript

  - by Mrgreen

  I have the following postscript code: /outputtext { /data exch def /rot exch def /xfont exch def /Times-Roman findfont xfont scalefont setfont /y1 exch def /x1 exch def x1 y1 moveto rot rotate data show } def % x y fontsize rotation (text) outputtext 20 300 12 0 (text1) outputtext 20 400 12 90 (text2) outputtext 20 500 12 90 (text3) outputtext 20 600 12 0 (text4) outputtext showpage The function simply outputs text based on a x, y co-ords and the text to display, there is also a variable for rotation. For some reason when I output text with a rotation of 0 degrees, all other text that comes after that will not work, I can't seem to figure out why this is the case. In the example above, 'text1' and 'text2' will display, but not 3 and 4.

• XmlSerializer throws exception when serializing dynamically loaded type

  - by Dr. Sbaitso

  Hi I'm trying to use the System.Xml.Serialization.XmlSerializer to serialize a dynamically loaded (and compiled class). If I build the class in question into the main assembly, everything works as expected. But if I compile and load the class from an dynamically loaded assembly, the XmlSerializer throws an exception. What am I doing wrong? I've created the following .NET 3.5 C# application to reproduce the issue: using System; using System.Collections.Generic; using System.Xml.Serialization; using System.Text; using System.Reflection; using System.CodeDom.Compiler; using Microsoft.CSharp; public class StaticallyBuiltClass { public class Item { public string Name { get; set; } public int Value { get; set; } } private List<Item> values = new List<Item>(); public List<Item> Values { get { return values; } set { values = value; } } } static class Program { static void Main() { RunStaticTest(); RunDynamicTest(); } static void RunStaticTest() { Console.WriteLine("-------------------------------------"); Console.WriteLine(" Serializing StaticallyBuiltClass..."); Console.WriteLine("-------------------------------------"); var stat = new StaticallyBuiltClass(); Serialize(stat.GetType(), stat); Console.WriteLine(); } static void RunDynamicTest() { Console.WriteLine("-------------------------------------"); Console.WriteLine(" Serializing DynamicallyBuiltClass..."); Console.WriteLine("-------------------------------------"); CSharpCodeProvider csProvider = new CSharpCodeProvider(new Dictionary<string, string> { { "CompilerVersion", "v3.5" } }); CompilerParameters csParams = new System.CodeDom.Compiler.CompilerParameters(); csParams.GenerateInMemory = true; csParams.GenerateExecutable = false; csParams.ReferencedAssemblies.Add("System.dll"); csParams.CompilerOptions = "/target:library"; StringBuilder classDef = new StringBuilder(); classDef.AppendLine("using System;"); classDef.AppendLine("using System.Collections.Generic;"); classDef.AppendLine(""); classDef.AppendLine("public class DynamicallyBuiltClass"); classDef.AppendLine("{"); classDef.AppendLine(" public class Item"); classDef.AppendLine(" {"); classDef.AppendLine(" public string Name { get; set; }"); classDef.AppendLine(" public int Value { get; set; }"); classDef.AppendLine(" }"); classDef.AppendLine(" private List<Item> values = new List<Item>();"); classDef.AppendLine(" public List<Item> Values { get { return values; } set { values = value; } }"); classDef.AppendLine("}"); CompilerResults res = csProvider.CompileAssemblyFromSource(csParams, new string[] { classDef.ToString() }); foreach (var line in res.Output) { Console.WriteLine(line); } Assembly asm = res.CompiledAssembly; if (asm != null) { Type t = asm.GetType("DynamicallyBuiltClass"); object o = t.InvokeMember("", BindingFlags.CreateInstance, null, null, null); Serialize(t, o); } Console.WriteLine(); } static void Serialize(Type type, object o) { var serializer = new XmlSerializer(type); try { serializer.Serialize(Console.Out, o); } catch(Exception ex) { Console.WriteLine("Exception caught while serializing " + type.ToString()); Exception e = ex; while (e != null) { Console.WriteLine(e.Message); e = e.InnerException; Console.Write("Inner: "); } Console.WriteLine("null"); Console.WriteLine(); Console.WriteLine("Stack trace:"); Console.WriteLine(ex.StackTrace); } } } which generates the following output: ------------------------------------- Serializing StaticallyBuiltClass... ------------------------------------- <?xml version="1.0" encoding="IBM437"?> <StaticallyBuiltClass xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"> <Values /> </StaticallyBuiltClass> ------------------------------------- Serializing DynamicallyBuiltClass... ------------------------------------- Exception caught while serializing DynamicallyBuiltClass There was an error generating the XML document.

• Generating VS 2005 .vcproj's by hand

  - by Kevin

  I'm working on a script that generates Visual Studio 2005 C++ project files (.vcproj). The script reads a makefile, then spits out a c++ project. INPUT: makefile --- OUTPUT: VS 2005 c++ project (.vcproj) However, when I try to build the auto-generated project in VS 2005, error outputs: "Unspecified Error." Evidently, I am not generating the VS 2005 .vcproj file correctly. Assuming that my c++ project file was malformed, I opened up VS 2005 and made a new C++ project. I actually copied the good, VS 2005-created project file to my non-working, malformed project file. I replaced the Name, Reference Includes (.libs), Compile Includes (.cc, .c), etc. in the good VS 2005 project with my malformed project file's information. However, I still cannot get VS 2005 to compile my .vcproj. Perhaps VS 2005 is very particular about the content of its .vcproj's? Please give me advice on how to manually generate a VS 2005 .vcproj. Thanks!

• What open source database platform is most easily transferred from my personal machine into a window

  - by Tom

  I would like eventual interaction with MS Dynamics SL and/or MindTouch Core (running on WMware) for eventual intranet and/or internet display. I guess I am asking for front and back end recommendations for a database I am constructing, but since this is my first major project I would greatly appreciate any help and advice. I would also love an opportunity to learn a new language so the code base could be in any language. I do have a few more related questions for discussion; What is the viability of using Google hosting to provide the service to the public for free? Should I implement plone or another CMS if I have a large amount of output? Is there a structuring questionnaire or standards publication I could reference? Does UML diagramming provide additional options for portability? Thank you.

• How do I flip a column in mysql that has data structured: 'last name, first name'?

  - by ggg

  I want to create a new column in a MYSQL table that has Fn Ln instead of Ln, Fn. Most of my data is printed Fn Ln. Another idea is to incorporate a string function each time there is an output (php based) but that seems to waste resources. Finally, I couldn't find the syntax (loop or foreach) for my php function anyway. Here is the working php function that I got from a previous post: $name = "Lastname, Firstname"; $names = explode(", ", $name); $name = $names[1] . " " . $names[0];

• Why Java SimpleDateFormat().parse() is printing weird formate?

  - by MAK

  My input is String formated as the following: 3/4/2010 10:40:01 AM 3/4/2010 10:38:31 AM My code is: DateFormat dateFormat = new SimpleDateFormat("dd/mm/yyyy hh:mm:ss aa"); try { Date today = dateFormat.parse(time); System.out.println("Date Time : " + today); } catch (ParseException e) { e.printStackTrace(); } the output is: Sun Jan 03 10:38:31 AST 2010 Sun Jan 03 10:40:01 AST 2010 I'm not sure from where the day (Sun) came from? or (AST)? and why the date is wrong? I just wanted to keep the same format of the original String date and make it into a Date object. I'm using Netbeans 6.8 Mac version.

• How do I plot the warping of DTW result using gnuplot?

  - by Ekkmanz

  Hello, Right now I have implemented Dynamic Time Warping algorithm for warping two 3D trajectories. Currently, gnuplot is my plotting tool of choice and it works fine when I plot multiple trajectories at a time. However, when I implement DTW one of the real use for plotting tool is to visualize the point warping, like this picture. Currently, the output of my DTW program is two time series in CSV files and another CSV file which indicate the warp (X in series 1 - Y in series 2). Is there any possible way to do that in gnuplot?
