• How to counter the "one true language" perspective?

  - by Rob Wells

  How do you work with someone when they haven't been able to see that there is a range of other languages out there beyond "The One True Path"? I mean someone who hasn't realised that the modern software professional has a range of tools in his toolbox. The person whose knee jerk reaction is, for example, "We must do this is C++!" "Everything must be done in C++!" What's the best approach to open people up to the fact that "not everything is a nail"? How may I introduce them to having a well-equipped toolbox, selecting the best tool for the job at hand?

• Agile and code release

  - by ring bearer

  Do you know of any agile process that is created for code releases? One of the main theme of agile is frequent releases and each company/client would have their own test/approval processes that control code releases. Most of the time these slow down the pace of "frequent releases" Currently we have a proprietary tool based workflow. The team who needs a code promotion needs to create a promotion request to one of the final UAT servers. Once this is complete, and once tests are done, certain customers, technical/non-technical managers need to approve, then it goes in to production deploy stage. Meanwhile no sprint planning meeting or anything of that sort. What is the code release process (Which is agile) that has worked for you?

• UIView Clipped By Statusbar until Autorotate

  - by TonyNeallon

  Hi There, Ive created a multiview application that uses multiple controllers to display and control views. The problem Im having is, when the simulator initially loads the view the header is partially covered by the bar at top of screen and the tool bar at the base is not touching the base of the screen. I used the Interface builder size attributes to control the view when the iphone rotates and it works perfectly. All smaps into place perfectly both in landscape and portrait mode AFTER a rotation but the problem is with the initial load before a rotation occurs. Your thoughts a much appreciated. Tony

• Setting a VCProject property to default

  - by Ofek Shilon

  I'm trying some VS2005 IDE macros to modify a large amount of projects (~80) within a solution. Some of the properties I wish to set do expose a programmatic interface to 'default', but many others do not. Is there a generic way to set such properties to their default? (eventually meaning erasing them from the .vcproj file) Simplified example, setting some random properties: Sub SetSomeProps() Dim prj As VCProject Dim cfg As VCConfiguration Dim toolCompiler As VCCLCompilerTool Dim toolLinker As VCLinkerTool Dim EnvPrj As EnvDTE.Project For Each EnvPrj In DTE.Solution.Projects prj = EnvPrj.Object cfg = prj.Configurations.Item(1) toolLinker = cfg.Tools("VCLinkerTool") If toolLinker IsNot Nothing Then ' Some tool props that expose a *default* interface' toolLinker.EnableCOMDATFolding = optFoldingType.optFoldingDefault toolLinker.OptimizeReferences = optRefType.optReferencesDefault toolLinker.OptimizeForWindows98 = optWin98Type.optWin98Default End If toolCompiler = cfg.Tools("VCCLCompilerTool") If toolCompiler IsNot Nothing Then ' How to set it to default? (*erase* the property from the .vcproj)' toolCompiler.CallingConvention = callingConventionOption.callConventionCDecl toolCompiler.WholeProgramOptimization = False toolCompiler.Detect64BitPortabilityProblems = False End If Next End Sub Any advice would be appreciated.

• Webdav -- GET on a directory

  - by Joe Cannatti

  I am beginning to build a tool that uses WebDAV. I am having trouble wrapping my head around something here. I think I am missing something conceptual. I can use PUT's to add files to the server. I can use GET's to read files from the server, but when I try to use GET on a directory I get a 403:Forbidden. I am using basic authentication. My code in MacRuby is as follows Net::HTTP.start('localhost') do |http| res = Net::HTTP::Get.new('http://localhost/webdav/') res.basic_auth 'jcannatti', 'webdav' http.request res end this returns <Net::HTTPForbidden 403 Forbidden readbody=true> however this Net::HTTP.start('localhost') do |http| res = Net::HTTP::Put.new('http://localhost/webdav/gorilla.txt') res.body = "testetsetest" res.basic_auth 'jcannatti', 'webdav' http.request res end returns <Net::HTTPCreated 201 Created readbody=true> What should happen when calling a GET on a WebDAV directory when everything is working correctly? thanks

• Static libraries, dynamic libraries, DLLs, entry points, headers ... how to get out of this alive?

  - by tunnuz

  Hello, I recently had to program C++ under Windows for an University project, and I'm pretty confused about static and dynamic libraries system, what the compiler needs, what the linker needs, how to build a library ... is there any good document about this out there? I'm pretty confused about the *nix library system as well (so, dylibs, the ar tool, how to compile them ...), can you point a review document about the current library techniques on the various architectures? Note: due to my poor knowledge this message could contain wrong concepts, feel free to edit it. Thank you Feel free to add more reference, I will add them to the summary. References Since most of you posted *nix or Windows specific references I will summarize here the best ones, I will mark as accepted answer the Wikipedia one, because is a good start point (and has references inside too) to get introduced to this stuff. Program Library Howto (Unix) Dynamic-Link Libraries (from MSDN) (Windows) DLL Information (StackOverflow) (Windows) Programming in C (Unix) An Overview of Compiling and Linking (Windows)

• How do you balance business process changes against the challenges of changing software?

  - by Achilles

  In my admittedly young career I've found myself writing code to support quirky business rules and processes. Inevitably these changes were always in some massively difficult code base and caused many issues. My question has a couple of parts: While software is a tool for businesses to make their lives easier, at what point do we as developers suggest a change in business process rather than in the software as the "magic bullet" to solve a particular problem. How do we as developers evangelize a certain level of reverence for the software as well as the difficulty involved in making changes simply to support the quirks of the business? I understand that these changes in business processes promote our industry, but in an analogy my father would understand: Which is easier, to melt down a hammer to forge a screwdriver to drive screws or to simply use nails since your hammer is already awesome...?

• HTML Chrome Audit Specify Image Dimensions

  - by AKRamkumar

  I just started using the chrome developer tools for some basic html websites and I used the audit tool. I had two identical images, one with the height and width attribute, and one without. On the Resources section, both the latency and the download time were identical. However, the Audit showed Specify image dimensions (1) A width and height should be specified for all images in order to speed up page display. Does this actually help? And are there any other ways to speed up page time? This is only a splash page for the website I am building and as such it is only html, no css or javascript or anything. I have already compressed the images but I want to speed up load time even more. Is there a way?

• Bitmapfontatlas cocos2d performance issue

  - by meboz

  This question was also asked in the cocos2d forums but they are a little slower than here. Hi, Im trying to resolve a performance issue in my game. I have all of my game images on the one spritesheet. I now have a score label for which i have generated a font file with the Hiero tool. Ideally I'd like to update my score label with the current score on every update. However there seems to be a significant performance hit when doing so, which i believe is the result of the game images texture and the font texture swapping each update. Can anyone suggest a way to avoid this? Possibly by combining the font images with the game images in the one image file to avoid the texture swapping? Cheers

• Error while installing dependencies for PyGTK on Mac OS 10.6.3

  - by Winston C. Yang

  I tried to install the following dependencies for PyGTK 2.16.0 (the Python GIMP Tool Kit) on Mac OS 10.6.3: glib 2.25.5 gettext-0.18 libiconv-1.13.1 When I tried to install glib, I got the following error message: gconvert.c:55:2: error: #error GNU libiconv not in use but included iconv.h is from libiconv The libiconv web page talks about a circular dependency between gettext and libiconv---build one, then build the other, then build the first again. I tried to do this, though possibly incorrectly. (Will the following work: make distclean; ./configure; make; sudo make install?) The author of a posting had the same problem, and he solved it by installing libiconv-1.13.1. Could anyone explain the error in more detail, and how to correct it?

• Click HTML except one element [ WITHOUT JQuery ]

  - by Tomirammstein

  I show us the code: (function (){ var element = document.getElementById('bar'), hideElement = document.getElementById('foo'), var html = document.getElementsByTagName('html')[0]; tool.onclick = function() { hideElement.style.display = 'block'; html.onclick = function() { hideElement.style.display = 'none'; } } })(); This piece of code work's fine, but, after clicking html, I can not reopen the hidden element. I want to click the html element and give display:none to hideElement, then to click the element id="bar", give to the hidden element display:block, but instead of click the element foo, click the html element. What I can do? Oh, i need help WITHOUT JQUERY, thanks :) EDIT: something like that : click on body except some other tag not working , but without JQuery,

• Are Symphony and CakePHP too slow to be usable?

  - by Aziz Light

  Until now, I have always said that CakePHP is too bloated and slow. I don't really know that, I just saw "some" benchmarks. What I really want to know, is that if those two frameworks (Symfony and CakePHP) are too slow to be usable in a way that the user will get frustrated. I already know that those frameworks are slower than other alternatives, but that's not the question. I ask the question because I want to create a project management web application and I still hesitate between a couple frameworks. I've had some trouble learning Zend, but imho I haven't tried hard enough. So in conclusion, in addition to the first question above, I would like to ask another question: If I want to create a project management tool (which is a pretty big project), which of the following should you suggest, considering the developement time, the speed of the resulting application, and the robustness of the final product: Symphony CakePHP Zend Framework Also I should mention that I don't know any of those frameworks, and that I want to learn one of them (at least).

• Essential skills of a Data Scientist

  - by harshsinghal

  I would like to know more about the relevant skills in the arsenal of a Data Scientist, and with new technologies coming in every day, how one picks and chooses the essentials. A few ideas germane to this discussion: Knowing SQL and the use of a DB such as MySQL, PostgreSQL was great till the advent of NoSql and non-relational databases. MongoDB, CouchDB etc. are becoming popular to work with web-scale data. Knowing a stats tool like R is enough for analysis, but to create applications one may need to add Java, Python, and such others to the list. Data now comes in the form of text, urls, multi-media to name a few, and there are different paradigms associated with their manipulation. What about cluster computing, parallel computing, the cloud, Amazon EC2, Hadoop ? OLS Regression now has Artificial Neural Networks, Random Forests and other relatively exotic machine learning/data mining algos. for company Thoughts?

• how to make tooltip move along with mouse?

  - by George2

  Hello everyone, I am using Silverlight 3 + VSTS 2008. I have a image (Multiscale image control) and I place tooltip on this image. The function of Tooltip works fine. Since the image is big (about 500 * 500 size), and since end user could move mouse on the picture, and I want to display tooltip position along with the mouse (i.e. when mouse moves, I want to tooltip move along with the mouse). Currently, the tooltip displays at a fixed position. Here is my current XAML code, any ideas how to solve this issue? <MultiScaleImage x:Name="msi" Height="500" Width="500"> <ToolTipService.ToolTip> <ToolTip Content="Here is a tool tip" Name="DeepZoomToolTip"></ToolTip> </ToolTipService.ToolTip> </MultiScaleImage> thanks in advance, George

• C#/Oracle: Specify Encoding/Character Set of Query?

  - by Reini

  I'm trying to fetch some Data of a Oracle 10 Database. Some cells are containing german umlauts (äöü). In my Administration-Tool (TOAD) I can see them very well: "Mantel für Damen" (Jacket for Women) This is my C# Code (simplified): var oracleCommand = new OracleCommand(sqlGetArticles, databaseConnection); var articleResult = oracleCommand.ExecuteReader(); string temp = articleResult.Read()["SomeField"].ToString(); Console.WriteLine(temp); The output is: "Mantel f?r Damen" Tryed on Debugging (moving mouse over variable), Debug-Window, Console-Window, File. I think I have to specify the Encoding/Character Set somwhere. But where?

• Metatool for automatic xml code generation

  - by iceman

  I want to develop a programming tool for developers which can do automatic xml code generation for specifying a GUI design and its controls. The aim is to allow non-programmers specify GUI controls(which in this case perform higher level task unlike WinForms ) from a GUI. So the xml code generated is essentially an internal representation which programmers can understand and further use in any automatic GUI generator. So the workflow is GUI(non-programmers)-xml(for programmers)-GUI(non-programmers). Is there a Microsoft project similar to this?

• How do you handle files that can't support concurrent edits in Mercurial?

  - by Scott Whitlock

  I'm using Mercurial with TortoiseHg. Each developer has their own repositories, and there's one central repository on the server for synchronizing our changes. (This will sound lame, but we're using it to manage the source for a legacy VB6 project. Nothing we can do about that...) As has been pointed out elsewhere, there is a big problem in VB6 with merging the .frx (form resources) files. So code changes seem to merge fine, but if two developers both make changes at the same time in the form design view, we can't merge. I'm ok with disallowing concurrent edits, but of course the whole point of Mercurial is that it's distributed so there is no option to force a file to be locked before editing. I don't believe there's a Mercurial solution for this, so I'm wondering: other developers who are using Mercurial for version control, do you have some 3rd party tool that assists with locking files for editing in the cases where it's necessary? Did we make a mistake using Mercurial instead of something like SVN?

• Open source / commercial alternative for jiffy.js?

  - by Marcel

  Hi, we'd like to measure "client side web site performance". i.e. we would like to have answers to the following questions: how long did it takt to load and render a webpage (including alle graphics scripts etc.) this bundled with additional informations like user-agent, operating system etc. a graphical tool to analyze the data would be perfect I know jiffy ( http://code.google.com/p/jiffy-web/wiki/Jiffy_js ) but that isn't maintained anymore. I would prefer either a hosted solution (like google analytics) or a java based solution that we deploy for ourselves. Do you know something like that? Thanks, Marc

• checking crc32 of a file

  - by agent154

  This is not really a "how to" question. Is there a "standard" file structure that applications use to store the checksums of files in a folder? I'm developing a tool to check various things like crc32, md5, sha1, sha256, etc... I'd like to have my program store the various hashes in files in the folder of what I'm checking. I know that there is a file commonly used called 'md5sums' or 'sha1sums'. But what about CRC? I haven't noticed any around. And if there is, what's the structure of it? Thanks.

• Data Integration/EAI Project Lessons Learned

  - by Greg Harman

  Have you worked on a significant data or application integration project? I'm interested in hearing what worked for you and what didn't and how that affected the project both during and after implementation (i.e. during ongoing operation, maintenance and expansion). In addition to these lessons learned, please describe the project by including a quick overview of: The data sources and targets. Specifics are not necessary, but I'd like to know general technology categories e.g. RDBMS table, application accessed via a proprietary socket protocol, web service, reporting tool. The overall architecture of the project as related to data flows. Different human roles in the project (was this all done by one engineer? Did it include analysts with a particular expertise?) Any third-party products utilized, commercial or open source.

• Create a Models Diagram Using Railroad

  - by SeeBees

  Railroad is a great UML tool for Ruby on Rails. It can automatically generate class diagrams of models and controllers. For models, a railroad-generated class diagram shows attributes of each model and the associations between one model and another. A sample diagram can be found here. It is very useful for a developer to see attributes and associations of models. While attributes and associations reveal the inner states and relationships of models, methods specify their behaviours. They are all desirable in a class diagram. I would like railroad to generate a class diagram that also lists methods for models, which will help me to know what each model does. I know methods are displayed in a diagram that is generated for controllers, but I don't see such an option for a diagram of models. Does someone know how to do that with railroad? Or is that possible? Thanks!
