  • Unreal Development Kit Hardware requirements?

    - by gojira666
    I am very interested in trying out the Unreal Development Kit for my own small to medium-sized hobby projects. I am wondering about the minimum hardware requirements. I have a Vaio Z laptop with dual-core 2.4 GHZ CPU and 2 GB RAM, and graphics chip is GeForce 9300M GS. Is it even practicable to run UDK on this hardware? Or do I need a "real" desktop PC?

  • How to stay financially organized easily when running a small web development company

    - by jls33fsls
    So I'm a programmer and I run my own web development company. In the past I have been able to get away with just doing some simple number crunching at the end of each year to do my taxes, but my company has grown substantially over the last year, and now that I am sitting down to do my taxes it has become an absolute nightmare because none of my information is organized at all. I want to be abel to easily keep track of my monthly and yearly financial data for my company (I use a Mac), any suggestions?

  • Make windows XP ask for password

    - by daramarak
    We have software that have some features that are so sensitive that we want to verify the identity of the user. Instead of using a own user/password scheme we would really like to either test the password against the user password in XP, or even make Windows self reauthenticate the user so we can make sure that it is an authorized person that accesses the function. Or software is only running on windows XP embedded. I do not know if this is possible at all, does windows have any such features?

  • Modifying / Resetting the Last reboot time

    - by user3711455
    I am trying to recreate a problem I encountered to try to confirm the root causes of it. One of the possible theory is that the problem is being caused because the server hadn't restarted for along time. Since I've already restarted the computer, Is there a way of resetting/modifying the "Last Reboot time" so the computer thinks it hasn't restarted for along time? I am using systeminfo | find "System Boot Time" The computer is running Windows XP Embedded if it helps. Thanks

  • Flash: How to make an embedded video not autoplay

    - by jb
    I'm embedding a Flash video into an HTML and would like the user to have to click it to begin playing. According to the Adobe <object> / <embed> element documentation, there are variety of methods to do this: 1) Add a Flash parameter inside the <object> tag: <param name="play" value="false"> 2) Add the attribute play inside the <embed> tag: <embed ... play="false"> 3) Add the attribute flashvars inside the <embed> tag: <embed ... flashvars="play=false"> Which is awesome. Only ... none of them work for me: http://johnboxall.github.com/test/flash/flash.htm My code looks like this now: <object width="590" height="475"> <param name="movie" value="untitled_skin.swf"> <param name="play" value="false"> <embed src="untitled_skin.swf" width="590" height="475" type="application/x-shockwave-flash" play="false" flashvars="autoplay=false&play=false" menu="false"></embed> </object> Anyone have any ideas? What am I doing wrong?

  • Fitting it together, database, reporting, applications in C#

    - by alvonellos
    Introduction Preamble I was hesitant to post this, since it's an application whose intricate details are defined elsewhere, and answers may not be helpful to others. Within the past few weeks (I was actually going to write a blog post about this after I finished) I've discovered that the barrier I'm encountering is one that's actually quite common for newer developers. This question is not so much about a specific thing as it is about piecing those things together. I've searched the internet far and wide, and found many tutorials on how to create applications that are kind of similar to what I'm looking for. I've also looked at hiring another, more experienced, developer to help me along, but all I've gotten are unqualified candidates that don't have the experience necessary and won't take care of the client or project like I will. I'd rather have the project never transpire than to release a solution that is half-baked. I've asked professors at my school, but they've not turned up answers to my question. I'm an experienced developer, and I've written many applications that are -- very abstractly -- close to what I'm doing, but my experiences from those applications aren't giving me enough leverage to solve this particular problem. I just hope that posting this article isn't a mistake for me to write. Project Description I have a project I'm working on for a client that is a rewrite of an application, originally written in Foxpro 2.6 by someone before me, that performs some analysis (which, sadly, I'm not allowed to disclose as per of my employment contract) on financial data. One day, after a long talk between the client and I -- where he intimately described his frustrations with all the bugs I've been hacking out of this code for 6 months now -- he told me to just rewrite it and gave me a month to write a good 1/8 of this 65k LOC Foxpro monstrosity. this 65k line of code foxpro monstrosity. It'll take me a good 3 - 6 months to rewrite this software (I know things the original programmer did not, like inheritance) going as I am right now, but I'm quickly discovering that I'm going to need to use databases. Prior to this contract I didn't even know about foxpro, and so I've had to learn foxpro on the fly, write procedures and make modifications to the database. I've actually come to like it, and this project would be rewritten in Foxpro if it were still a supported language, because over the past few months, I've come to like the features of Foxpro that make it so easy to develop data-driven applications. I once perfomed an experiment, comparing C# to Foxpro. What took me 45 minutes in C# took me two in Foxpro, and I knew C# prior to Foxpro. I was hoping to leverage the power of C#, but it intimidates me that in foxpro, you can have one line of code and be using a database. Prior to this, I have never written any serious database development from scratch. All the applications that I've written are in a different league. They are either completely data-naive or data-naive enough that I can get away with not using a database through serialization or by designing algorithms that work with the data in a manner that is stateless, so there is no need to worry about databases. I've come to realize, very quickly, that serialization and my efficacy with data structures has been my crutch all these years that's prevented me from adventuring into databases, and has consequently hindered my success in real-world programming. Sure, I've written some database stuff in Perl and Python, and I've done forms and worked with relational databases and tables, I'm a wizard in Access and Excel (seriously) and can do just about anything, but it just feels unnatural writing SQL code in another language... I don't mind writing SQL, and I don't It's that bridge between the database and the program code that drives me absolutely bonkers. I hope I'm not the only one to think this, but it bothers me that I have to create statements like the following string sSql = "SELECT * from tablename" When there's really no reason for that kind of unchecked language binding between two languages and two API's. Don't get my wrong, SQL is great, but I don't like the idea that, when executing commands on a SQL database, that one must intermix database and application software, and there's no database independence, which means that different versions of different databases can break code. This isn't very nice. The nicest thing about Foxpro is the cohesiveness between programming language and database. It's so easy, and Foxpro makes it easy, because the tool just fits the task. I can see why so many developers have created a career with this language, because it lowered the barrier of entry to data-driven applications that so many businesses need. It was wonderful. For my purposes today, with the demands and need for community support, extensibility, and language features, Foxpro isn't a solution that I feel would be the right tool for the job. I'm also worried about working too heavy with the database, because I've seen data-driven .NET applications have issues with database caches, running out of memory, and objects in the database not being collected. (Memory leaks) And OH the queries. Which one, how, and why? There are a plethora of different ways that a database can be setup, I think I counted 5 or 6 different kinds of database applications alone that I can chose from. That is a great mountain for me to climb when I don't even know where to begin when it comes to writing data-driven applications. The problem isn't that I don't know SQL or that I don't know C#. I know both and have worked with both extensively. It's making them work together that's the problem, and it's something I've never done in C# before. Reports The client likes paper. The data needs to be printed out in a format that is extensible, layered, and easy to use. I have never done reporting before, and so this is a bit of a problem. From the data source comes crystal reports, and so there's a dependency on the database, from what I understand. Code reuse A large part of the design decision that I've gone through so far is to break the task of writing a piece of this software into routines and modular DLL's and so forth such that much of the code can be reused. For example, when I setup this database, I want to be able to reuse the same database code over and over again. I also want to make sure that when the day comes that another developer is here, that he/she will be able to pick up just where I left off. The quicker I develop these applications, the better off I am. Tasks & Goals In my project, I need to write routines that apply algorithms and look for predefined patterns in financial data. Additionally, I need to simulate trading based on predefined algorithms and data. Then I need to prepare reports on that data. Additionally, I need to have a way to change the code base for this application quickly and effectively, without hacking together some band-aid solution for a problem that really needs a trauma ward. Special Considerations The solution must be fast, run quickly on existing hardware, and not be too much of a pain to maintain and write. I understand that anything I write I'm married to -- I'm responsible for the things that I write because my reputation and livelihood is dependent on it. Do I really need a database? What about performance? Performance was such a big issue that I hand wrote a data structure that is capable of performing 2 billion operations, using a total of 4 gigs of memory in under 1/4 of a second using the standard core two duo processor. I could not find a similar, pre-written data structure in C# to perform this task. What setup do I use in terms of database? What about reporting? I'd prefer to have PDF's generated, but I'd like to be able to visually sketch those reports and then just have a ReportFactory of some sort, that when I pass some variables in, it just does that data. About Me I'm a lone developer for a small business in this area. This is the first time I've done this and I've never had the breadth and depth of my knowledge tested. I'm incredibly frustrated with this project because I feel incredibly overwhelmed with the task at hand. I'm looking for that entry level point where I can draw a line and say "this is what I need to do" Conclusion I may have not been clear enough on my post. I'm still new to this whole thing, and I've been doing my best to contribute back to the community that I've leached so much knowledge from. I'd be glad to edit my post and add more information if possible. I'm looking for a big-picture solution or design process that helps me get off the ground in this world of data-driven applications, because I have a feeling that it's going to be concentric to my entire career as a programmer for some time. Specifically, if you didn't get it from the rest of the post (I may not have been clear enough) I really need some guidance as to where to go in terms of the design decisions for this project. Some things that'll be useful will be a pro/con list for the different kinds of database projects available in VS2010. I've tried, but generating that list has been as hard as solving the problem itself... If you could walk a developer writing a data-driven application for the first time in C#, how would you do that? Where would you point them to?

  • Embedded pdf object steals focus and will not let it go

    - by Kristian Hebert
    Hi guys, I was given the task of adding some usability to one of our applications, ie. make sure that every controll has a shortcut key, and that they can be reached by "tabbing" through the page. The gui runs in a IE. control on a winform, and consists of asp.net pages, so basically it is just asp.net always running in internet explorer. My problem is that one of the pages has an embeded pdf in it, like so: <object tabindex="-1" height="273" width="663" visible="false" type="Application/pdf" data="showpdf.ashx#navpanes=0"></object> showpdf.ashx is an httphandler, that streams the pdf contents to the response. It does not handle focus in any way. Now when I run this page, the pdf application steals focus, no matter what I do to set it to another control. And when it takes focus, I cannot take it back with the keyboard. Only a mouseclick on the page will set it to another control. I have tried to set focus in code behind OnPreRender, or in jevescript, but no luck. It seems that the http handler always runs after all the other code, and it sets focus on the pdf object. Any thought would be greatly appreciated.

  • Open source embedded filesystem (or single file virtual filesystem, or structured storage) library f

    - by Ioan
    I'm not sure what the "general" name of something like this might be. I'm looking for a library that gives me a file format to store different types of binary data in an expanding single file. open source, non-GPL (LGPL ok) C interface the file format is a single file multiple files within using a POSIX-like file API (or multiple "blobs" within using some other API) file/structure editing is done in-place reliable first, performant second Examples include: the virtual drives of a virtual machine whefs HDF CDF NetCDF Problems with the above: whefs doesn't appear to be very mature, but best describes what I'm after HDF, CDF, NetCDF are usable (also very reliable and fast), but they're rather complicated and I'm not entirely convinced of their support for opaque binary "blobs" Edit: Forgot to mention, one other relevant question: http://stackoverflow.com/questions/1361560/simple-virtual-filesystem-in-c-c Another similar question: http://stackoverflow.com/questions/374417/is-there-an-open-source-alternative-to-windows-compound-files Edit: Added condition of in-place editing.

  • Embedded Glassfish - logging

    - by Walter White
    Hi all, I have migrated from log4j to logback and also am transitioning to Glassfish from Jetty. I haven't updated my logback configuration from what I had used with Jetty and consequently am not seeing any logs being written. What logging provider should I use? Should I just do my configuration with the Glassfish loggers in domain.xml? <access-log rotation-interval-in-minutes="15" rotation-suffix="yyyy-MM-dd"/> <log-service file="${com.sun.aas.instanceRoot}/logs/server.log" log-rotation-limit-in-bytes="2000000"> <module-log-levels/> </log-service> These are the defaults in domain.xml. I'd like to split the longs up into several files as well as control log level for each package. I think I can figure out how to configure them, but should I use Glassfish logging or can I use logback? Walter

  • Popover with embedded navigation controller doesn't respect size on back nav

    - by quixoto
    I have a UIPopoverController hosting a UINavigationController, which contains a small hierarchy of view controllers. I followed the docs and for each view controller, I set the view's popover-context size like so: [self setContentSizeForViewInPopover:CGSizeMake(320, 500)]; (size different for each controller) This works as expected as I navigate forward in the hierarchy-- the popover automatically animates size changes to correspond to the pushed controller. However, when I navigate "Back" through the view stack via the navigation bar's Back button, the popover doesn't change size-- it remains as large as the deepest view reached. This seems broken to me; I'd expect the popover to respect the sizes that are set up as it pops through the view stack. Am I missing something? Thanks.

  • Embedded ZXing - what am I missing?

    - by Brian515
    Hi all, Sorry if this has been answered before, but I am trying to make an application that will include the ability to scan barcodes on Android. I'm looking at using ZXing as the library, however, I want to embed the scanner in my application so that the user doesn't have to have the ZXing barcode scanner installed to use my application. From the description of ZXing, it sounds like this is possible. I've gotten as far as building ZXing, linking it into my project in Eclipse, then creating a new reader instance. However, I'm lost when it comes to starting the barcode reader and implementing the callbacks. IMO, this is when the documentation here gets hazy. If someone could explain how to use ZXing properly, that would be of great help. Cheers!

  • Using Lightbox with _Screen

    Although, I have to admit that I discovered Bernard Bout's ideas and concepts about implementing a lightbox in Visual FoxPro quite a while ago, there was no "spare" time in active projects that allowed me to have a closer look into his solution(s). Luckily, these days I received a demand to focus a little bit more on this. This article describes the steps about how to integrate and make use of Bernard's lightbox class in combination with _Screen in Visual FoxPro. The requirement in this project was to be able to visually lock the whole application (_Screen area) and guide the user to an information that should not be ignored easily. Depending on the importance any current user activity should be interrupted and focus put onto the notification. Getting the "meat", eh, source code Please check out Bernard's blog on Foxite directly in order to get the latest and greatest version. As time of writing this article I use version 6.0 as described in this blog entry: The Fastest Lightbox Ever The Lightbox class is sub-classed from the imgCanvas class from the GdiPlusX project on VFPx and therefore you need to have the source code of GdiPlusX as well, and integrate it into your development environment. The version I use is available here: Release GDIPlusX 1.20 As soon as you open the bbGdiLightbox class the first it, VFP might ask you to update the reference to the gdiplusx.vcx. As we have the sources, no problem and you have access to Bernard's code. The class itself is pretty easy to understand, some properties that you do not need to change and three methods: Setup(), ShowLightbox() and BeforeDraw() The challenge - _Screen or not? Reading Bernard's article about the fastest lightbox ever, he states the following: "The class will only work on a form. It will not support any other containers" Really? And what about _Screen? Isn't that a form class, too? Yes, of course it is but nonetheless trying to use _Screen directly will fail. Well, let's have look at the code to see why: WITH This .Left = 0 .Top = 0 .Height = ThisForm.Height .Width = ThisForm.Width .ZOrder(0) .Visible = .F.ENDWITH During the setup of the lightbox as well as while capturing the image as replacement for your forms and controls, the object reference Thisform is used. Which is a little bit restrictive to my opinion but let's continue. The second issue lies in the method ShowLightbox() and introduced by the call of .Bitmap.FromScreen(): Lparameters tlVisiblilty* tlVisiblilty - show or hide (T/F)* grab a screen dump with controlsIF tlVisiblilty Local loCaptureBmp As xfcBitmap Local lnTitleHeight, lnLeftBorder, lnTopBorder, lcImage, loImage lnTitleHeight = IIF(ThisForm.TitleBar = 1,Sysmetric(9),0) lnLeftBorder = IIF(ThisForm.BorderStyle < 2,0,Sysmetric(3)) lnTopBorder = IIF(ThisForm.BorderStyle < 2,0,Sysmetric(4)) With _Screen.System.Drawing loCaptureBmp = .Bitmap.FromScreen(ThisForm.HWnd,; lnLeftBorder,; lnTopBorder+lnTitleHeight,; ThisForm.Width ,; ThisForm.Height) ENDWITH * save it to a property This.capturebmp = loCaptureBmp ThisForm.SetAll("Visible",.F.) This.DraW() This.Visible = .T.ELSE ThisForm.SetAll("Visible",.T.) This.Visible = .F.ENDIF My first trials in using the class ended in an exception - GdiPlusError:OutOfMemory - thrown by the Bitmap object. Frankly speaking, this happened mainly because of my lack of knowledge about GdiPlusX. After reading some documentation, especially about the FromScreen() method I experimented a little bit. Capturing the visible area of _Screen actually was not the real problem but the dimensions I specified for the bitmap. The modifications - step by step First of all, it is to get rid of restrictive object references on Thisform and to change them into either This.Parent or more generic into This.oForm (even better: This.oControl). The Lightbox.Setup() method now sets the necessary object reference like so: *====================================================================* Initial setup* Default value: This.oControl = "This.Parent"* Alternative: This.oControl = "_Screen"*====================================================================With This .oControl = Evaluate(.oControl) If Vartype(.oControl) == T_OBJECT .Anchor = 0 .Left = 0 .Top = 0 .Width = .oControl.Width .Height = .oControl.Height .Anchor = 15 .ZOrder(0) .Visible = .F. EndIfEndwith Also, based on other developers' comments in Bernard articles on his lightbox concept and evolution I found the source code to handle the differences between a form and _Screen and goes into Lightbox.ShowLightbox() like this: *====================================================================* tlVisibility - show or hide (T/F)* grab a screen dump with controls*====================================================================Lparameters tlVisibility Local loControl m.loControl = This.oControl If m.tlVisibility Local loCaptureBmp As xfcBitmap Local lnTitleHeight, lnLeftBorder, lnTopBorder, lcImage, loImage lnTitleHeight = Iif(m.loControl.TitleBar = 1,Sysmetric(9),0) lnLeftBorder = Iif(m.loControl.BorderStyle < 2,0,Sysmetric(3)) lnTopBorder = Iif(m.loControl.BorderStyle < 2,0,Sysmetric(4)) With _Screen.System.Drawing If Upper(m.loControl.Name) == Upper("Screen") loCaptureBmp = .Bitmap.FromScreen(m.loControl.HWnd) Else loCaptureBmp = .Bitmap.FromScreen(m.loControl.HWnd,; lnLeftBorder,; lnTopBorder+lnTitleHeight,; m.loControl.Width ,; m.loControl.Height) EndIf Endwith * save it to a property This.CaptureBmp = loCaptureBmp m.loControl.SetAll("Visible",.F.) This.Draw() This.Visible = .T. Else This.CaptureBmp = .Null. m.loControl.SetAll("Visible",.T.) This.Visible = .F. Endif {loadposition content_adsense} Are we done? Almost... Although, Bernard says it clearly in his article: "Just drop the class on a form and call it as shown." It did not come clear to my mind in the first place with _Screen, but, yeah, he is right. Dropping the class on a form provides a permanent link between those two classes, it creates a valid This.Parent object reference. Bearing in mind that the lightbox class can not be "dropped" on the _Screen, we have to create the same type of binding during runtime execution like so: *====================================================================* Create global lightbox component*==================================================================== Local llOk, loException As Exception m.llOk = .F. m.loException = .Null. If Not Vartype(_Screen.Lightbox) == "O" Try _Screen.AddObject("Lightbox", "bbGdiLightbox") Catch To m.loException Assert .F. Message m.loException.Message EndTry EndIf m.llOk = (Vartype(_Screen.Lightbox) == "O")Return m.llOk Through runtime instantiation we create a valid binding to This.Parent in the lightbox object and the code works as expected with _Screen. Ease your life: Use properties instead of constants Having a closer look at the BeforeDraw() method might wet your appetite to simplify the code a little bit. Looking at the sample screenshots in Bernard's article you see several forms in different colors. This got me to modify the code like so: *====================================================================* Apply the actual lightbox effect on the captured bitmap.*====================================================================If Vartype(This.CaptureBmp) == T_OBJECT Local loGfx As xfcGraphics loGfx = This.oGfx With _Screen.System.Drawing loGfx.DrawImage(This.CaptureBmp,This.Rectangle,This.Rectangle,.GraphicsUnit.Pixel) * change the colours as needed here * possible colours are (220,128,0,0),(220,0,0,128) etc. loBrush = .SolidBrush.New(.Color.FromArgb( ; This.Opacity, .Color.FromRGB(This.BorderColor))) loGfx.FillRectangle(loBrush,This.Rectangle) EndwithEndif Create an additional property Opacity to specify the grade of translucency you would like to have without the need to change the code in each instance of the class. This way you only need to change the values of Opacity and BorderColor to tweak the appearance of your lightbox. This could be quite helpful to signalize different levels of importance (ie. green, yellow, orange, red, etc...) of notifications to the users of the application. Final thoughts Using the lightbox concept in combination with _Screen instead of forms is possible. Already Jim Wiggins comments in Bernard's article to loop through the _Screen.Forms collection in order to cascade the lightbox visibility to all active forms. Good idea. But honestly, I believe that instead of looping all forms one could use _Screen.SetAll("ShowLightbox", .T./.F., "Form") with Form.ShowLightbox_Access method to gain more speed. The modifications described above might provide even more features to your applications while consuming less resources and performance. Additionally, the restrictions to capture only forms does not exist anymore. Using _Screen you are able to capture and cover anything. The captured area of _Screen does not include any toolbars, docked windows, or menus. Therefore, it is advised to take this concept on a higher level and to combine it with additional classes that handle the state of toolbars, docked windows and menus. Which I did for the customer's project.

  • Inserting THEAD element into embedded HTML using jQuery

    - by robalot
    I'm trying to use jQuery to insert HTML into a table element. I've been messing variations of the selector (below) with no luck. Can someone help me? My Selector: $j('#ctl00_body_gridData_dom').children('table:first').append("<thead><tr><td colspan='6'>&nbsp;</td><td align='center' colspan='7'>EM SPECS</td><td align='center' colspan='7'>FISH</td><td colspan='11'>&nbsp;</td></tr></thead>"); Here's what I am trying to do...

  • Telling a UITextField to become first responder while embedded in a UITableViewCell

    - by Jasarien
    I have a UITextField that is a subview of a UITableViewCell. When my view loads, I want the text field to become first responder. I have a pointer to the text field in the table cell, so to do this I am trying: [myTextField becomeFirstResponder]; This returns NO all the time, regardless of when it's called, which according to the docs means the text field refused to become first responder... What am I doing wrong? Edit: The text field properly responds to being touched. It bring up the keyboard then. It's only when telling it to become first responder programmatically that the problem happens.

  • Playing dynamically embedded sound object via Javascript

    - by Vikram Goyal
    I need to background load some WAV files for an HTML page using AJAX. I use AJAX to get the details of the WAV files, then use the embed tag, and I can confirm that the files have loaded successfully because when I set autostart to true, the files play. However, I need the files to play only when the user clicks on a button (or an event is fired). The following is my code to preload these files: function preloadMedia() { for(var i = 0; i < testQuestions.length; i++) { var soundEmbed = document.createElement("embed"); soundEmbed.setAttribute("src", "/media/sounds/" + testQuestions[i].mediaFile); soundEmbed.setAttribute("hidden", true); soundEmbed.setAttribute("id", testQuestions[i].id); soundEmbed.setAttribute("autostart", false); soundEmbed.setAttribute("width", 0); soundEmbed.setAttribute("height", 0); soundEmbed.setAttribute("enablejavascript", true); document.body.appendChild((soundEmbed)); } } I use the following code to play the file (based on what sound file that user wants to play) function soundPlay(which) { var sounder = document.getElementById(which); sounder.Play(); } Something is wrong here, as none of the browsers I have tested on play the files using the code above. There are no errors, and the code just returns. I would have left it at that (that is - I would have convinced the client to convert all WAV's to MP3 and use MooTools). But I realized that I could play the sound files, which were not dynamically embeded. Thus, the same soundPlay function would work for a file embeded in the following manner: <embed src="/media/sounds/hug_sw1.wav" id="sound2" width="0" heigh="0" autostart="false" enablejavascript="true"/> anywhere within the HTML. And it plays well in all the browsers. Anyone have a clue on this? Is this some sort of undocumented security restriction in all the browsers? (Please remember that the files do get preloaded dynamically, as I can confirm by setting the autostart property to true - They all play). Any help appreciated.

  • Software development metrics and reporting

    - by David M
    I've had some interesting conversations recently about software development metrics, in particular how they can be used in a reasonably large organisation to help development teams work better. I know there have been Stack Overflow questions about which metrics are good to use - like this one, but my question is more about which metrics are useful to which stakeholders, and at what level of aggregation. As an example, my view is that code coverage is a useful metric in the following ways (and maybe others): For a team's own internal use when combined with other measurements. For facilitating/enabling/mentoring teams, where it might be instructive when considered on a team-by-team basis as a trend (e.g. if team A and B have coverage this month of 75 and 50, I'd be more concerned with team A than B if the previous month they'd had 80 and 40). For senior management when presented as an aggregated statistic across a number of teams or a whole department. But I don't think it's useful for senior management to see this on a team-by-team basis, as this encourages artifical attempts to bolster coverage with tests that merely exercise, rather than test, code. I'm in an organisation with a couple of levels in its management hierarchy, but where the vast majority of managers are technically minded and able (with many still getting their hands dirty). Some of the development teams are leading the way in driving towards agile development practices, but others lag, and there is now a serious mandate from the top for this to be the way the organisation works. A couple of us are starting a programme to encourage this. In this sort of an organisation, what sort of metrics do you think are useful, to whom, why, and at what level of aggregation? I don't want people to feel their performance is being assessed based on a metric that they can artificially influence; at the same time, the senior management are going to want some sort of evidence that progress is being made. What advice or caveats can you provide based on experience in your own organisations? EDIT We are definitely wanting to use metrics as a tool for organisational improvement not as a tool for individual performance measurement.

  • Creating an ITemplate from a String

    - by Damon
    I do a lot of work with control templates, and one of the pieces of functionality that I've always wanted is the ability to build a ITemplate from a string.  Throughout the years, the topic has come up from time to time, and I never really found anything about how to do it. though I have run across a number of postings from people who are also wanting the same capability.  As I was messing around with things the other day, I stumbled on how to make it work and I feel really foolish for not figuring it out sooner. ITemplate is an interface that exposes a single method named InstantiateIn.  I've been searching for years for some magical .NET framework component that would take a string and convert it into an ITemplate, when all along I could just build my own.  Here's the code: /// <summary> ///   Allows string-based ITempalte implementations /// </summary> public class StringTemplate : ITemplate {     #region Constructor(s)     ////////////////////////////////////////////////////////////////////////////////////////////     /// <summary>     ///   Constructor     /// </summary>     /// <param name="template">String based version of the control template.</param>     public StringTemplate(string template)     {         Template = template;     }     /// <summary>     ///   Constructor     /// </summary>     /// <param name="template">String based version of the control template.</param>     /// <param name="copyToContainer">True to copy intermediate container contents to the instantiation container, False to leave the intermediate container in place.</param>     public StringTemplate(string template, bool copyToContainer)     {         Template = template;         CopyToContainer = copyToContainer;     }     ////////////////////////////////////////////////////////////////////////////////////////////     #endregion     #region Properties     ////////////////////////////////////////////////////////////////////////////////////////////     /// <summary>     ///   String based template     /// </summary>     public string Template     {         get;         set;     }     /// <summary>     ///   When a StringTemplate is instantiated it is created inside an intermediate control     ///   due to limitations of the .NET Framework.  Specifying True for the CopyToContainer     ///   property copies all the controls from the intermediate container into instantiation     ///   container passed to the InstantiateIn method.     /// </summary>     public bool CopyToContainer     {         get;         set;     }     ////////////////////////////////////////////////////////////////////////////////////////////     #endregion     #region ITemplate Members     ////////////////////////////////////////////////////////////////////////////////////////////     /// <summary>     ///   Creates the template in the specified control.     /// </summary>     /// <param name="container">Control in which to make the template</param>     public void InstantiateIn(Control container)     {         Control tempContainer = container.Page.ParseControl(Template);         if (CopyToContainer)         {             for (int i = tempContainer.Controls.Count - 1; i >= 0; i--)             {                 Control tempControl = tempContainer.Controls[i];                 tempContainer.Controls.RemoveAt(i);                 container.Controls.AddAt(0, tempControl);             }                         }         else         {             container.Controls.Add(tempContainer);         }     }     ////////////////////////////////////////////////////////////////////////////////////////////     #endregion } //class Converting a string into a user control is fairly easy using the ParseControl method from a Page object.  Fortunately, the container passed into the InstantiateIn method has a Page property.  One caveat, however, is that the Page property only has a reference to a Page if the container is located ON the page.  If you run into this problem, you may have to find a creative way to get the Page reference (you can add it to the constructor, store it in the request context, etc).  Another issue that I ran into is that the ParseControl creates a new control, parses the string template, places any controls defined in the template onto the new control it created, and returns that new control with the template on it.  You cannot pass in your own container. Adding this directly to the container provided as a parameter in the InstantiateIn means that you end up with an additional "level" in the control hierarchy.  To avoid this, I added code in that removes each control from the intermediate container and places it into the actual container.  I am not, however, sure about the performance penalty associated with moving a bunch of control from one place to another, nor am I completely sure if doing such a move completely screws something up if you have a code behind, etc.  It seems to work when it's just a template, but my testing was ever-so-slightly shy of thorough when it comes to other crazy scenarios.  As a catch-all, I added a Boolean property called CopyToContainer that allows you to turn the copying on or off depending on your desires and needs.

  • Jruby embedded modules and classes.

    - by James Moore
    Hey, I have a ruby file as follows: module Example class Myclass def t_st "Hello World!" end end end now if this was just a class I would be able to use the following java code: ScriptEngine jruby = new ScriptEngineManager().getEngineByName("jruby"); jruby.eval(new BufferedReader(new FileReader("example.rb"))); Object example = jruby.eval("myclass.new"); However, this class rests inside a module. Calling the same code as above produces the error: Exception in thread "main" org.jruby.embed.EvalFailedException: uninitialized constant myclass In addition, calling: Object example = jruby.eval("Example"); The module returns no error. So one would assume this follows the format for Ruby. Object example = jruby.eval("Example::myclass.new"); Again however, I get the same error as before. Can anyone help? As there is little documentation on JRuby? Thanks

  • Security in Software

    The term security has many meanings based on the context and perspective in which it is used. Security from the perspective of software/system development is the continuous process of maintaining confidentiality, integrity, and availability of a system, sub-system, and system data. This definition at a very high level can be restated as the following: Computer security is a continuous process dealing with confidentiality, integrity, and availability on multiple layers of a system. Key Aspects of Software Security Integrity Confidentiality Availability Integrity within a system is the concept of ensuring only authorized users can only manipulate information through authorized methods and procedures. An example of this can be seen in a simple lead management application.  If the business decided to allow each sales member to only update their own leads in the system and sales managers can update all leads in the system then an integrity violation would occur if a sales member attempted to update someone else’s leads. An integrity violation occurs when a team member attempts to update someone else’s lead because it was not entered by the sales member.  This violates the business rule that leads can only be update by the originating sales member. Confidentiality within a system is the concept of preventing unauthorized access to specific information or tools.  In a perfect world the knowledge of the existence of confidential information/tools would be unknown to all those who do not have access. When this this concept is applied within the context of an application only the authorized information/tools will be available. If we look at the sales lead management system again, leads can only be updated by originating sales members. If we look at this rule then we can say that all sales leads are confidential between the system and the sales person who entered the lead in to the system. The other sales team members would not need to know about the leads let alone need to access it. Availability within a system is the concept of authorized users being able to access the system. A real world example can be seen again from the lead management system. If that system was hosted on a web server then IP restriction can be put in place to limit access to the system based on the requesting IP address. If in this example all of the sales members where accessing the system from the 192.168.1.23 IP address then removing access from all other IPs would be need to ensure that improper access to the system is prevented while approved users can access the system from an authorized location. In essence if the requesting user is not coming from an authorized IP address then the system will appear unavailable to them. This is one way of controlling where a system is accessed. Through the years several design principles have been identified as being beneficial when integrating security aspects into a system. These principles in various combinations allow for a system to achieve the previously defined aspects of security based on generic architectural models. Security Design Principles Least Privilege Fail-Safe Defaults Economy of Mechanism Complete Mediation Open Design Separation Privilege Least Common Mechanism Psychological Acceptability Defense in Depth Least Privilege Design PrincipleThe Least Privilege design principle requires a minimalistic approach to granting user access rights to specific information and tools. Additionally, access rights should be time based as to limit resources access bound to the time needed to complete necessary tasks. The implications of granting access beyond this scope will allow for unnecessary access and the potential for data to be updated out of the approved context. The assigning of access rights will limit system damaging attacks from users whether they are intentional or not. This principle attempts to limit data changes and prevents potential damage from occurring by accident or error by reducing the amount of potential interactions with a resource. Fail-Safe Defaults Design PrincipleThe Fail-Safe Defaults design principle pertains to allowing access to resources based on granted access over access exclusion. This principle is a methodology for allowing resources to be accessed only if explicit access is granted to a user. By default users do not have access to any resources until access has been granted. This approach prevents unauthorized users from gaining access to resource until access is given. Economy of Mechanism Design PrincipleThe Economy of mechanism design principle requires that systems should be designed as simple and small as possible. Design and implementation errors result in unauthorized access to resources that would not be noticed during normal use. Complete Mediation Design PrincipleThe Complete Mediation design principle states that every access to every resource must be validated for authorization. Open Design Design PrincipleThe Open Design Design Principle is a concept that the security of a system and its algorithms should not be dependent on secrecy of its design or implementation Separation Privilege Design PrincipleThe separation privilege design principle requires that all resource approved resource access attempts be granted based on more than a single condition. For example a user should be validated for active status and has access to the specific resource. Least Common Mechanism Design PrincipleThe Least Common Mechanism design principle declares that mechanisms used to access resources should not be shared. Psychological Acceptability Design PrincipleThe Psychological Acceptability design principle refers to security mechanisms not make resources more difficult to access than if the security mechanisms were not present Defense in Depth Design PrincipleThe Defense in Depth design principle is a concept of layering resource access authorization verification in a system reduces the chance of a successful attack. This layered approach to resource authorization requires unauthorized users to circumvent each authorization attempt to gain access to a resource. When designing a system that requires meeting a security quality attribute architects need consider the scope of security needs and the minimum required security qualities. Not every system will need to use all of the basic security design principles but will use one or more in combination based on a company’s and architect’s threshold for system security because the existence of security in an application adds an additional layer to the overall system and can affect performance. That is why the definition of minimum security acceptably is need when a system is design because this quality attributes needs to be factored in with the other system quality attributes so that the system in question adheres to all qualities based on the priorities of the qualities.
