  • Make emacs autocomplete Ruby methods

    - by Mad Wombat
    Is there a way to make emacs pull autocompletions of ruby methods the way Eclipse and NetBeans do? That is if I type File. and press CTRL-space in Eclipse I will get a list of File methods. Same with variables. I have installed autocomplete plugin, ruby-mode, rinari and cedet, but so far it will complete local variable and method names, but will not native ones.

  • What can I do to improve a project if there is a no-listening situation. Developers vs Management

    - by NazGul
    Hi all, I hope that I'm not the only one and I can get a answer from someone with more experience than me, so I can think cleaner and I don't get depressed with this developer's life. I'm working as developer for a small company three years now. In that three years I'm working in the same project and sincerely, I think this project could be used as a CASE STUDY because it has all the situations that cannot happen in a project and that makes a project fails. To begin with, and I believe you've already noticed, the project has 3 years already (develoment only) and is still unfinished, because in every meeting there is a "new priority" ,or a "new problem" to be solve or a "new feature" to be add. So, first problem is no target set. How can you know when something is finished if you don't know what you want? I understand Management, because they see an oportunity and try to get that, but I don't understand how can they not see (or hear us) that they'll lose all they already have and what they'll eventually get. Second, there is no team group. My team consists of three people, a Senior Developer, a DBA and, finally, I for all the work (support, testing, new features, bug fixing, meeting, projet management of clients, etc) aka Junior Developer. The first (senior developer), does not perform any tests on his changes, so, most of the time, his changes give us problems (us = me, since I'm the one who will fix it). The second (DBA) is an uncompromising person and you can not talk to him, believe me, I tried! In his view, everything he does is fantastic... even if it is the most complicated to make it... And he does everything he wants, even if we need that only for 5 months later and would help some extra-hand to do the things we have to do for now. As you can see, there is very hard to work with no help... Third, there is no testings. Every... I repeat, Every release of the project, the customers wants to kill us, because there is a lot of bugs. Management? They say that they want tests before the release. Us? We say the same. Time? No time. Management? There is always some time to open the application and click in some buttons. Us? Try to explain that it is not so simple. Management doesn't care... end of story. Actually, must of the bugs could be avoid with a rigorous work... Some people just want to do the show to the Management. "Did you ask for this? Cool, it's done. Bugs? The Do-all-the-work guy will solve." Unfortunally for me, sometimes the Do-all-the-work also has to finish it. And to makes this all better, I'm the person who will listen the complaints from the customers. Cool, huh? I know, everyone makes mistakes. But there is mistakes and mistakes... To complete, in the Management view, "the problem is the lack of an individual project management", because we cannot do all the stuff they ask, even if there is no PM for the project itself. And ask us to work overtime without any reward... I do say all this stuff to the management and others members, but by telling this, the I'm the bad guy, the guy who is complain when everything is going well... but we need to work overtime... sigh What can I do to make it works? Anyone has a situation like this, what did you do? I hope you could understand my problem, my English is a little rusty. Thanks.

  • How to make emacs properly indent if-then-else construct in elisp

    - by Mad Wombat
    When I indent if-then-else construct in emacs lisp, the else block doesn't indent properly. What I get is: (defun swank-clojure-decygwinify (path) "Convert path from CYGWIN UNIX style to Windows style" (if (swank-clojure-cygwin) (replace-regexp-in-string "\n" "" (shell-command-to-string (concat "cygpath -w " path))) (path))) where else form is not indented at the same level as the then form. Is there an obvious way to fix this?

  • US (Postal) ZIP codes: ZIP+4 vs. ZIP in web applications

    - by FreekOne
    Hi guys, I am currently writing a web application intended for US users that asks them to input their ZIP code and I just found out about the ZIP+4 code. Since I am not from the US and getting a user's correct ZIP code is important, I have no idea which format I should use. Could anyone (preferably from the US) please clarify what's the deal with the +4 digits and how important are they ? Is it safe to use only the plain 5-digit ZIP ? Thank you in advance !

  • VS2010's "Public Property <PropertyName> As <DataType> vs. Public var

    - by Velika2
    In VS2008, I used to type Public Property <PropName> As <dataType> and hit the Enter key and the IDE editor would automatically expand it out to a full blown property block. Now, from what I understand, a new feature of 2010 is that the compiler automatically "expands" the short syntax above into the same IL code that you would get with the full property GET AND SET sub methods that were are accustomed to seeing before in the editor. But functionality, how the heck is this any different than just having a Public class level variable? If the only diff is what it compiles to and if otehrwise there is no functional difference, isn't the new way less efficient than the old since it involves more code than just having a class level memory variable? Public as I thought that if you weren't going to have code behind your properties that they were essentially the same. I guess the diffrenece is that they just added the keyword "Property" but functionality, their is no diff, eh?

  • How to use the new VS 2010 configuration transforms and apply them to other .config files?

    - by Wallace
    I have setup some configuration transforms in my web.config for my connectionStrings, etc. But I have separated out some areas of my web.config into separate files, ex) appSettings.config. How can I configure Visual Studio and MSBuild to perform config transformations on these additional config files? I have already followed the approach of the web.config to relate the files together within my web application project file, but transformations are not automatically applied. <ItemGroup> <Content Include="appSettings.Debug.config"> <DependentUpon>appSettings.config</DependentUpon> </Content> </ItemGroup>

  • C++ vs. C++/CLI: Const qualification of virtual function parameters

    - by James McNellis
    [All of the following was tested using Visual Studio 2008 SP1] In C++, const qualification of parameter types does not affect the type of a function (8.3.5/3: "Any cv-qualifier modifying a parameter type is deleted") So, for example, in the following class hierarchy, Derived::Foo overrides Base::Foo: struct Base { virtual void Foo(const int i) { } }; struct Derived : Base { virtual void Foo(int i) { } }; Consider a similar hierarchy in C++/CLI: ref class Base abstract { public: virtual void Foo(const int) = 0; }; ref class Derived : public Base { public: virtual void Foo(int i) override { } }; If I then create an instance of Derived: int main(array<System::String ^> ^args) { Derived^ d = gcnew Derived; } it compiles without errors or warnings. When I run it, it throws the following exception and then terminates: An unhandled exception of type 'System.TypeLoadException' occurred in ClrVirtualTest.exe Additional information: Method 'Foo' in type 'Derived'...does not have an implementation. That exception seems to indicate that the const qualification of the parameter does affect the type of the function in C++/CLI (or, at least it affects overriding in some way). However, if I comment out the line containing the definition of Derived::Foo, the compiler reports the following error (on the line in main where the instance of Derived is instantiated): error C2259: 'Derived': cannot instantiate abstract class If I add the const qualifier to the parameter of Derived::Foo or remove the const qualifier from the parameter of Base::Foo, it compiles and runs with no errors. I would think that if the const qualification of the parameter affects the type of the function, I should get this error if the const qualification of the parameter in the derived class virtual function does not match the const qualification of the parameter in the base class virtual function. If I change the type of Derived::Foo's parameter from an int to a double, I get the following warning (in addition to the aforementioned error, C2259): warning C4490: 'override': incorrect use of override specifier; 'Derived::Foo' does not match a base ref class method So, my question is, effectively, does the const qualification of function parameters affect the type of the function in C++/CLI? If so, why does this compile and why are there no errors or warnings? If not, why is an exception thrown?

  • How to select nth element of particular type in enlive?

    - by Mad Wombat
    I am trying to scrape some data from a page with a table based layout. So, to get some of the data I need to get something like 3rd table inside 2nd table inside 5th table inside 1st table inside body. I am trying to use enlive, but cannot figure out how to use nth-of-type and other selector steps. To make matters worse, the page in question has a single top level table inside the body, but (select data [:body : :table]) returns 6 results for some reason. What the hell am I doing wrong?

  • Administrators vs Programmers: Who's got more people Interaction / Working hours?

    - by sanksjaya
    Well, I've heard programmers get to interact with other programmers quiet a lot. But, who gets to meet a lot of new people on a daily basis at work without getting the feeling "Goosh! I'm stuck with him/this for another year :(" - Admins or Coders? And what kind of people domain do each get to interact with? Secondly, I've had this myth for a long time that unlike programmers, Network/System/Security Admins get locked-up in a den and juiced up late nights and early mornings. Most of the time they had to slip out of work without being noticed. But recently one of my seniors from my grad school told he had to work late and on weekends for a product release. How true and often does this happen with programmers and admins?

  • How to overcome an apparent REST vs. DRY dilemma in rails?

    - by Chris
    A rails app I'm working on features examples of quadratic equations. Obviously, these are all of a common structure: ax^2 + bx + c = 0. I don't want to store every single example of these. I'd rather generate them from a template. Storing hundreds of possible versions of this structure seems highly wasteful and un-DRY. On the other hand, if I generate them, I can't access them again reliably as I could if they were simply multiple database objects. I'm sure there must be a way to overcome this, but I'm still learning rails and I'm obviously not grasping something here. Thanks.

  • What benefits are there to storing Javascript in external files vs in the <head>?

    - by RenderIn
    I have an Ajax-enabled CRUD application. If I display a record from my database it shows that record's values for each column, including its primary key. For the Ajax actions tied to buttons on the page I am able to set up their calls by printing the ID directly into their onclick functions when rendering the HTML server-side. For example, to save changes to the record I may have a button as follows, with '123' being the primary key of the record. <button type="button" onclick="saveRecord('123')">Save</button> Sometimes I have pages with Javascript generating HTML and Javascript. In some of these cases the primary key is not naturally available at that place in the code. In these cases I took a shortcut and generate buttons like so, taking the primary key from a place it happens to be displayed on screen for visual consumption: ... <td>Primary Key: </td> <td><span id="PRIM_KEY">123</span></td> ... <button type="button" onclick="saveRecord(jQuery('#PRIM_KEY').text())">DoSomething</button> This definitely works, but it seems wrong to drive database queries based on the value of text whose purpose was user consumption rather than method consumption. I could solve this by adding a series of additional parameters to various methods to usher the primary key along until it is eventually needed, but that also seems clunky. The most natural way for me to solve this problem would be to simply situate all the Javascript which currently lives in external files, in the <head> of the page. In that way I could generate custom Javascript methods without having to pass around as many parameters. Other than readability, I'm struggling to see what benefit there is to storing Javascript externally. It seems like it makes the already weak marriage between HTML/DOM and Javascript all the more distant. I've seen some people suggest that I leave the Javascript external, but do set various "custom" variables on the page itself, for example, in PHP: <script type="text/javascript"> var primaryKey = <?php print $primaryKey; ?>; </script> <script type="text/javascript" src="my-external-js-file-depending-on-primaryKey-being-set.js"></script> How is this any better than just putting all the Javascript on the page in the first place? There HTML and Javascript are still strongly dependent on each other.

  • jQuery tag editor function

    - by Mad Hatter
    I'm using jQuery Tag Editor (http://blog.crazybeavers.se/wp-content/demos/jquery.tag.editor/) for a school project. Everything works perfect, but i'm not able to retrieve the array of tags that I added. This is my code: $("#allTags").click(function () { var tags = $("#tagEditor").tagEditor().getTags(); alert(tags); }); The array doesn't return anything. This is the code from the jQuery Tag Editor: (function ($) { $.fn.extend({ tagEditor: function (options) { var defaults = { separator: ',', items: [], className: 'tagEditor', confirmRemoval: false, confirmRemovalText: 'Do you really want to remove the tag?', completeOnSeparator: false, completeOnBlur: false, initialParse: true, } var options = $.extend(defaults, options); var listBase, textBase = this, hiddenText; var itemBase = []; this.getTags = function () { return itemBase.join(options.separator); }; ...

  • Weird result with apache vs lighttpd in reverse proxy.

    - by northox
    I have an Apache server running in reverse proxy mode in front of a Tomcat java server. It handle HTTP and HTTPS and send those request back and forth to the Tomcat server on an internal HTTP port. I'm trying to replace the reverse proxy with Lighttpd. Here's the problem: while asking for the same HTTPS url, while using Apache as the reverse proxy, the Tomcat server redirect (302) to an HTTPS page but with Lighttpd it redirect to the same page in HTTP (not HTTPS). What does Lighttpd could do different in order to have a different result from the backend server? In theory, using Apache or Lighttpd server as a reverse proxy should not change anything... but it does. Any idea? I'll try to find something by sniffing the traffic on the backend tomcat server.

  • ADF vs. EJB/Spring: Where should I invest my time?

    - by Arthur Huxley
    I am a junior Java SE developer, planning to become a Java Standard Edition professional. Which technologies/frameworks will be the smartest thing for me to learn? I will invest a lot of time and energy on the technologies that I eventually choose and it will be the basis for my carreer. I need to choose carefully. I have one question in particular regarding Oracle ADF: How can it be better than Spring or EJB 3.x? No offense to the ADF developers - and please excuse my ignorance - but is there a reason for using ADF other than locking customers to Oracle products? If ADF is an inferior technology I fear I will be making a mistake choosing to specialize in ADF.

  • How to make emacs stay in the current directory

    - by Mad Wombat
    When I start working on a project in emacs, I use M-x cd to get into the project root directory. But every time I use C-x C-f to open a file in one of the subdirectories (like app/model/Store.rb) emacs changes current directory to that of the file. Is there a way to make emacs stay at the root?

  • DirectX 9 HLSL vs. DirectX 10 HLSL: syntax the same?

    - by numerical25
    For the past month or so, I have been busting my behind trying to learn DirectX. So I've been mixing back back and forth between DirectX 9 and 10. One of the major changes I've seen in the two is how to process vectors in the graphics card. One of the drastic changes I notice is how you get the GPU to recognize your structs. In DirectX 9, you define the Flexible Vertex Formats. Your typical set up would be like this: #define CUSTOMFVF (D3DFVF_XYZRHW | D3DFVF_DIFFUSE) In DirectX 10, I believe the equivalent is the input vertex description: D3D10_INPUT_ELEMENT_DESC layout[] = { {"POSITION",0,DXGI_FORMAT_R32G32B32_FLOAT, 0 , 0, D3D10_INPUT_PER_VERTEX_DATA, 0}, {"COLOR",0,DXGI_FORMAT_R32G32B32A32_FLOAT, 0 , 12, D3D10_INPUT_PER_VERTEX_DATA, 0} }; I notice in DirectX 10 that it is more descriptive. Besides this, what are some of the drastic changes made, and is the HLSL syntax the same for both?

  • Visual Studio: are there uninstall conflicts? (2008 vs 2010)

    - by loldop
    I have a history of Visual Studios: Once upon a time I installed Windows 7... First, I installed Visual Studio 2008 (Professional Edition) After that, I installed SP1 pack for it. And at last I installed Visual Studio 2010. But one day... several updates crash Visual Studio 2008. And I want to uninstall it. So, how to do this and is there no conflicts in Visual Studio 2010 after uninstallation of Visual Studio 2008?

  • Custom Java events with listeners vs. a JMS based implementation?

    - by Joe Dean
    My application requires events to be fired based on some specific activities that happen. I'm trying to determine if I should create my own event handling system using the Java EventObject with custom listeners similar to Java AWT Or should I use a JMS implementation? I was considering either apache's Qpid or ActiveMQ solution. I'm exploring these options at the moment and was wondering if anyone has experience with Qpid or ActiveMQ and can offer some advise (e.g., pros, cons to consider, etc) Also, if anyone has any suggestions for building a simple event handling system... if it's even worth while to consider this over a JMS based solution.

  • Adding WCF service reference adds DataContract types too

    - by Avi Shilon
    Hi everybody, I've used Visual Studio's Add Service Reference feature to add a service (actually it is a workflow service, created in WF4 RC1, but I don't think this makes any difference), and it also added the DataContracts that the service uses. At first this seemed fine, because All I've had in the DataContracts was simply properties, with no implementations. But now I've added code in the constructor of one data contracts that initializes creates an instance of one of the properties that exposes a list of other DCs, and when I've updated the service reference via VS (2010 RC1), the implementation was not updated. What should I do? Should I use my DCs instead of the ones created by VS or should I use the ones VS created? I've noticed that the properties in the VS-generated DCs contain some additional logic for checking equality in the setters and they also implement some interfaces too (like IExtensibleDataObject and INotifyPropertyChanged) which might get handy I guess in the future (I'm not knowledgeable at WCF). Thank you for your time folks, Avi

  • Cucumber vs. built-in testing? [Rails]

    - by yuval
    I asked a question about different testing frameworks yesterday. This question can be found here. Now that I have a better understanding of the different frameworks, I have a very simple question: With a basic understanding, but very limited experience with writing tests with rails' built in testing framework (basic assertions), would it be okay for me to jump directly to testing with RSpec, Webrat, and Cucumber? Thank you! As a side note: yes, this is an opinion based question, but I feel that the input received to this question is valuable enough to the community to keep this question open. Thanks.
