  • How to get VS or Xcode warning with something like "x = x++"?

    - by Jim Buck
    In the spirit of undefined behavior associated with sequence points such as “x = ++x” is it really undefined?, how does one get the compiler to complain about such code? Specifically, I am using Visual Studio 2010 and Xcode 4.3.1, the latter for an OSX app, and neither warned me about this. I even cranked up the warnings on VS2010 to "all", and it happily compiled this. (For the record, VS2010's version added 1 to the variable where Xcode's version kept the variable unchanged.)

  • When good programmers go bad!

    - by Ed Bloom
    Hi, I'm a team lead/dev who manages a team of 10 programmers. Most of them are hard working talented guys. But of late, I've got this one person who while highly talented and has delivered great work for me in the past, has just become completely unreliable. It's not his ability - that is not in question - he's proven that many times. He just looks bored now. Is blatantly not doing much work (despite a LOT of pressure being put on the team to meet tight deadlines etc.) He just doesn't seem to care and looks bored. I'm partially guilty for not having addressed this before now - I was afraid to have to lose a talented guy given the workload I've got on. But at this stage it's becoming a problem and affecting those around him. Can anyone spare their thoughts or words of wisdom on how I should go about dealing this. I want the talented AND motivated guy back. Otherwise he's gonna have to go. Thanks, Ed

  • C++ Set Erase Entry Question

    - by Wallace
    Hi. I encountered a problem here. I'm using C++ multiset. This is the test file. Score: 3-1 Ben Steven Score: 1-0 Ben Score: 0-0 Score: 1-1 Cole Score: 1-2 Ben I'm using while loop and ifstream (fin1) to read in from the test file above. multiset<string, less<string> > myset; while(!fin1.eof()) { fin1 >> scoreName; if(scoreName == "Score:") { //calculates number of matches played } else { goalCheck = scoreName.substr(1,1); if(goalCheck == "-") { string lGoal, rGoal; lGoal = scoreName.substr(0,1); rGoal = scoreName.substr(2,1); int leftGoal, rightGoal; leftGoal = atoi(lGoal.c_str()); rightGoal = atoi(rGoal.c_str()); if(leftGoal > rightGoal) //if team wins { //some computations } else if(leftGoal < rightGoal) //if team loses { //computations } else if(leftGoal == rightGoal) //if team draws { //computations } else { myset.insert(myset.begin(), scoreName); } } } I'm inserting all names into myset (regardless of wins/loses/draws) in my last else statement. But I only require the names of those matches who won/draw. Those names whose matches lost will not be included in myset. In the test file above, there's only one match that lost (1-2) and I wanted to remove "Ben". How can I do that? I tried to use myset.erase(), but I'm not sure how to get it point to Ben and remove it from myset. Any help is much appreciated. Thanks.

  • When should I be cautious using about data binding in .NET?

    - by Ben McCormack
    I just started working on a small team of .NET programmers about a month ago and recently got in a discussion with our team lead regarding why we don't use databinding at all in our code. Every time we work with a data grid, we iterate through a data table and populate the grid row by row; the code usually looks something like this: Dim dt as DataTable = FuncLib.GetData("spGetTheData ...") Dim i As Integer For i = 0 To dt.Rows.Length - 1 '(not sure why we do not use a for each here)' gridRow = grid.Rows.Add() gridRow(constantProductID).Value = dt("ProductID").Value gridRow(constantProductDesc).Value = dt("ProductDescription").Value Next '(I am probably missing something in the code, but that is basically it)' Our team lead was saying that he got burned using data binding when working with Sheridan Grid controls, VB6, and ADO recordsets back in the nineties. He's not sure what the exact problem was, but he remembers that binding didn't work as expected and caused him some major problems. Since then, they haven't trusted data binding and load the data for all their controls by hand. The reason the conversation even came up was because I found data binding to be very simple and really liked separating the data presentation (in this case, the data grid) from the in-memory data source (in this case, the data table). "Loading" the data row by row into the grid seemed to break this distinction. I also observed that with the advent of XAML in WPF and Silverlight, data-binding seems like a must-have in order to be able to cleanly wire up a designer's XAML code with your data. When should I be cautious of using data-binding in .NET?

  • Should Development / Testing / QA / Staging environments be similar?

    - by Walter White
    Hi all, After much time and effort, we're finally using maven to manage our application lifecycle for development. We still unfortunately use ANT to build an EAR before deploying to Test / QA / Staging. My question is, while we made that leap forward, developers are still free to do as they please for testing their code. One issue that we have is half our team is using Tomcat to test on and the other half is using Jetty. I prefer Jetty slightly over Tomcat, but regardless we using WAS for all the other environments. My question is, should we develop on the same application server we're deploying to? We've had numerous bugs come up from these differences in environments. Tomcat, Jetty, and WAS are different under the hood. My opinion is that we all should develop on what we're deploying to production with so we don't have the problem of well, it worked fine on my machine. While I prefer Jetty, I just assume we all work on the same environment even if it means deploying to WAS which is slow and cumbersome. What are your team dynamics like? Our lead developers stepped down from the team and development has been a free for all since then. Walter

  • Why is Microsoft under-supporting or under-developping VBNET?

    - by Will Marcouiller
    I ran into a situation where the lack of some features has become somewhat frustrating while developping in VB.NET 2.0. Since my first day of programming, I've always been a C programmer, and still am. Naturally, I chose C# as my favorite .NET language. Recently, a customer of mine has obliged that all of his development projects which disregard SharePoint development have to be written in VB.NET 2.0, that is to avoid conflictual systems to come into some problems. That is a legitimate choice of his which I approve somehow, since he's running some old central systems and is slowly migrating toward latest technologies. As for me, I would have prefered to go with C#, but then, never having done much VB in my life, I see it as an opportunity to learn somethings new, how to handle this and that in VBNET, etc. Except that the syntax is really too verbose for me, which is a pain! I got used to it and that is fine. However, I recently wanted to use the InternalsVisibleToAttribute which I discovered lastly here on SO. But then, in addition to not being able to have lambda expression that returns no value, which I discovered months ago, today I learn that I can't use the attribute in VBNET! Here is what I have read in an article: [...] Sorry VB.Net developers, Microsoft is again shunning you guys and this attribute is NOT available to you.... :( And here is the link: InternalsVisibleTo: Testing internal methods in .Net 2.0 I have heard from Anders Hejlsberg mouth while watching a Webcast from his presentation of .NET 4.0 Framework that the VBNET team was working or has worked in collaboration with the C# team (Eric Lippert and others) in order to bring VBNET to offer the same features as C# offers. But then, I say to myself that the VBNET team has a huge step forward to make, if already in .NET 2.0, some of the most important features lacked! So my question is this: Why is Microsoft under-supporting or under-developping VBNET? Will VBNET ever be lacking the C# features?

  • Any suggestions for good automated web load testing tool?

    - by fmunkert
    What are some good automated tools for load testing (stress testing) web applications, that do not use record and replay of HTTP network packets? I am aware that there are numerous load testing tools on the market that record and replay HTTP network packets. But these are unsuitable for my purpose, because of this: The HTTP packet format changes very often in our application (e.g. when we optimize an AJAX call). We do not want to adapt all test scripts just because there is a slight change in HTTP packet format. Our test team shall not need to know any internals about our application to write their test scripts. A tool that replays HTTP packets, however, requires the team to know the format of HTTP requests and responses, such that they can adapt details of the replayed HTTP packets (e.g. user name). The automated load testing tool I am looking for should be able to let the test team write "black box" test scripts such as: Invoke web page at URL http://... . First, enter XXX into text field XXX. Then, press button XXX. Wait until response has been received from web server. Verify that text field XXX now contains the text XXX. The tool should be able to simulate up to several 1000 users, and it should be compatible with web applications using ASP.NET and AJAX.

  • How to add a Web Part Zone to a SharePoint wiki page?

    - by Hitesh
    Hi, I have a team site. I understand that the default home page of a team site is a wiki page. I want to add a web part zone to this page. How can I do that? By default it already has Web Part Zone -. You can use SharePoint designer to add a web part to this zone and it works fine. But you are not able to add a web part to this zone using SharePoint web UI? Ususally when you have a web part zone in a page, using SharePoint web UI, it allows to you add/remove a web part. But it is not the case with the web part zone on the default home page of a team site. Also is there any way I can add a web part zone to this page? I do know that you can easily add web parts into wiki page content. But I want to add a new web part zone where users can add/remove web parts. Thanks, Hitesh

  • Standardizing a Release/Tools group on a specific language

    - by grahzny
    I'm part of a six-member build and release team for an embedded software company. We also support a lot of developer tools, such as Atlassian's Fisheye, Jira, etc., Perforce, Bugzilla, AnthillPro, and a couple of homebrew tools (like my Django release notes generator). Most of the time, our team just writes little plugins for larger apps (ex: customize workflows in Anthill), long-term utility scripts (package up a release for QA), or things like Perforce triggers (don't let people check into a specific branch unless their change description includes a bug number; authenticate against Active Directory instead of Perforce's internal passwords). That's about the scale of our problems, although we sometimes tackle something slightly more sizable. My boss, who is reasonably technical, has asked us to standardize on one or two languages so we can more easily substitute for each other. He's advocating bash scripts and Perl, due to their universality and simplicity. I can see his point--we mostly do "glue", so why not use "glue" languages rather than saddle ourselves with something designed for much larger projects? Since some of the tools we work with are Java-based, we do need to use something that speaks JVM sometimes. (The path of least resistance for these projects is BeanShell and Groovy.) I feel a tremendous itch toward language advocacy, but I'm trying to avoid saying "We should use Python 'cause I like it and Perl is gross." Instead, I'm trying to come up with a good approach to defining our problem set: what problems do we solve with scripts? Would we benefit from a library of common functions by our team, or are most of our projects more isolated? What is it reasonable to expect my co-workers to learn? What languages give us the most ease of development and ease of modification? Can you folks suggest some useful ways to approach this problem, both for my own thinking process and to help me facilitate some brainstorming among my coworkers?

  • Oracle syntax - should we have to choose between the old and the new?

    - by Martin Milan
    Hi, I work on a code base in the region of about 1'000'000 lines of source, in a team of around eight developers. Our code is basically an application using an Oracle database, but the code has evolved over time (we have plenty of source code from the mid nineties in there!). A dispute has arisen amongst the team over the syntax that we are using for querying the Oracle database. At the moment, the overwhelming majority of our queries use the "old" Oracle Syntax for joins, meaning we have code that looks like this... Example of Inner Join select customers.*, orders.date, orders.value from customers, orders where customers.custid = orders.custid Example of Outer Join select customers.custid, contacts.ContactName, contacts.ContactTelNo from customers, contacts where customers.custid = contacts.custid(+) As new developers have joined the team, we have noticed that some of them seem to prefer using SQL-92 queries, like this: Example of Inner Join select customers.*, orders.date, orders.value from customers inner join orders on (customers.custid = orders.custid) Example of Outer Join select customers.custid, contacts.ContactName, contacts.ContactTelNo from customers left join contacts on (customers.custid = contacts.custid) Group A say that everyone should be using the the "old" syntax - we have lots of code in this format, and we ought to value consistency. We don't have time to go all the way through the code now rewriting database queries, and it wouldn't pay us if we had. They also point out that "this is the way we've always done it, and we're comfortable with it..." Group B however say that they agree that we don't have the time to go back and change existing queries, we really ought to be adopting the "new" syntax on code that we write from here on in. They say that developers only really look at a single query at a time, and that so long as developers know both syntax there is nothing to be gained from rigidly sticking to the old syntax, which might be deprecated at some point in the future. Without declaring with which group my loyalties lie, I am interested in hearing the opinions of impartial observers - so let the games commence! Martin. Ps. I've made this a community wiki so as not to be seen as just blatantly chasing after question points...

  • Active Record two belongs_to calls to the same model

    - by ethyreal
    In linking a sports event to two teams, at first this seemed to make since: events - id:integer - integer:home_team_id - integer:away_team_id teams - integer:id - string:name However I am troubled by how I would link that up in the active record model: class Event belongs_to :home_team, :class_name => 'Team', :foreign_key => "home_team_id" belongs_to :away_team, :class_name => 'Team', :foreign_key => "away_team_id" end Is that the best solution? In an answer to a similar question I was pointed to single table inheritance, and then later found polymorphic associations. Neither of which seemed to fit this association. Perhaps I am looking at this wrong, but I see no need to subclass a team into home and away teams since the distinction is only in where the game is played. I thought also about a has_many through association but that seems two much as I will only ever need two teams, but those two teams don't belong to any one event. event_teams - integer:event_id - integer:team_id - boolean:is_home Is there a cleaner more semantic way for making these associations in active record? Thanks

  • Advantages of Using Linux as primary developer desktop

    - by Nick N
    I want to get some input on some of the advantages of why developers should and need to use Linux as their primary development desktop on a daily basic as opposed to using Windows. This is particulary helpful when your Dev, QA, and Production environments are Linux. The current analogy that I keep coming back to is. If I build my demo car as a Ford Escort, but my project car is a Ford Mustang, it doesn't make sense at all. I'm currently at an IT department that allows dual boot with Windows and Linux, but some run Linux while the vast majority use Windows. Here's several advantages that I've came up with since using Linux as a primary desktop. Same Exact operating system as Dev, QA, and Production Same Scripts (.sh) instead of maintaining (.bat and *.sh). Somewhat mitigated by using cygwin, but still a bit different. Team learns simple commands such as: cd, ls, cat, top Team learns Advanced commands like: pkill, pgrep, chmod, su, sudo, ssh, scp Full access to installs typically for Linux, such as RPM, DEB installs just like the target environments. The list could go on and on, but I want to get some feedback of anything that I may have missed, or even any disadvantages (of course there are some). To me it makes sense to migrate an entire team over to using Linux, and using Virtual Box, running Windows XP VM's to test functional items that 95% of most of the world uses. This is similar but a little different thread going on here as well. link text

  • Programming methods design phase assignment

    - by Shakir
    Hey, i have an assignment (NCC) which deals with the design phase. The Scenario is that you have four soccer divisions (divisions 1,2,3 and 4) which consist of 22 teams each and hence each team plays 42 games (home and away). The concept is similar to the barclays premier league whereby ranking is based on points or else goal difference or else goals scored by team. The difference is that the top 2 teams are promoted and the bottom 2 are relegated and this includes Div 1 and Div 4 as the top 2 of Div1 are promoted to the national league which is above division 1 regional league and bottom 2 of Div4 are relegated to the local league below Division 4 regional league. Hence there are 3 total leagues and 4 divisions in the regional league (which has 22 teams each). Now the referee has to add the result of the match and thus automatic tables have to be generated now, There are two reports League Tables for 4 divisions List of all results for any chosen team during the season by date it was played on There are a couple of things to be done... i know its gonna be terrible to make everything but atleast explain to me how i should go about drawing these and what things i should include (generally) Logical Data Structure Diagram (DSD) for each report Preliminary Program Structure (PSD) for each report Detailed Program Specification for each report Flowchart for each report There are other things but i think our teacher will give us clear "clues" for it Thanks a lot Update - Project so far: Data Structure Diagram Preliminary Program Structure

  • collection_select not working as expected

    - by kgb
    First time I've come to use collection_select in a project and I've hit a wall with it. A Profile has_one Team, Team has_many Profile. In my view for editing profiles I have this. <td><%= f.collection_select(:team_id, @team, :id, :title) %></td> Which populates the drop down with titles of teams as expected. The couple of examples I have read seem to use it in a very similar way. I can't figure out when the profile is saved why it isn't populating the team_id field in my DB. In the development log the team_id is being passed. Processing ProfilesController#update (for 127.0.0.1 at 2010-03-28 22:49:16) [PUT] Parameters: {"commit"=>"Update", "profile"=>{"dob(1i)"=>"2010", "second_name"=>"", "dob(2i)"=>"3", "role"=>"", "dob(3i)"=>"28", "project"=>"", "specialties"=>"", "about"=>"", "team_id"=>"1", "status"=>"", "first_name"=>""}, "authenticity_token"=>"sdTiFPGj9JCO3OEge5EGNGxZbQSsq9ME5LP342EBjyc=", "id"=>"3"} The update controller is the standard scaffold one, this has worked fine for all other additions to the profile model I'd made previously. Am I missing something obvious?

So I am comparing the LoggedIn UserId with this list(SELECT TeamMemberUserId FROM TeamMember WHERE UserId = @LoggedInUserId)

  • After I apply custom logic, next UI action crashes my app.

    - by DanF
    I've got an team (eveningRoster) that I'm making a button add employees to. The team is really a relationship to that night's event, but it's represented with an AC. I wanted to make sure an employee did not belong to the team before it adds, so I added a method to MyDocument to check first. It seems to work, the error logs complete, but after I've added a member, the next time I click anything, the program crashes. Any guesses why? Here's the code: -(IBAction)playsTonight:(id)sender { NSArray *selection = [fullRoster selectedObjects]; NSArray *existing = [eveningRoster arrangedObjects]; //Result will be within each loop. BOOL result; //noDuplicates will stay YES until a duplicate is found. BOOL noDuplicates = YES; //For the loop: int count; for (count = 0; count < [selection count]; count++){ result = [existing containsObject:[selection objectAtIndex:count]]; if (result == YES){ NSLog(@"Duplicate found!"); noDuplicates = NO; } } if (noDuplicates == YES){ [eveningRoster addObjects:[fullRoster selectedObjects]]; NSLog(@"selected objects added."); [eveningTable reloadData]; NSLog(@"Table reloaded."); } [selection release]; [existing release]; return; }

  • Hide Image Title in Slimbox

    - by Stephen
    My issue is a lot like this solved thread, except I'm using Slimbox 2: http://stackoverflow.com/questions/940994/hide-image-title-tool-tip-popup-on-mouse-rollover-or-hover When you hover over an image, the "Title" attribute pops up. I need HTML in my image title in Slimbox. So, of course, when you're hovering, the "Title" attribute shows all the HTML code. The code works perfectly when you're viewing the image in Slimbox so no problems there. I just need the Title attribute to be hidden/modified not to show this HTML code. I tried to change Q.title in slimbox.js to something else (like captionname). Then changed the HTML to call for: <a href="images/team/large.jpg" title="Joe Smith" captionname="URL" rel="lightbox-team"><img src="images/team/small.jpg" class ="headline" border="1" hspace="2" /></a> "Joe Smith" displays as the Title but when you view the image in Slimbox, captionname does not come up at all and neither does the Title. It's just blank where it should be. What do I need to modify in slimbox2.js to make this work?

  • How do you fix loading plugins in eclipse 3.5.1 on linux?

    - by Jay R.
    I have two linux boxes. Both Fedora 11 x64. On one, I downloaded the eclipse-java-galileo-SR1-linux-gtk-x86_64.tar.gz. I unpacked it to /opt/eclipse-3.5.1/ and used the Install New Software... item to install the SVN team provider and the Polarion SVN connectors. Everything works. On the second, I copied the tar.gar for eclipse there, and then tried to follow the same steps. When I get to the install SVN team provided, eclipse downloads it and claims to install it and asks to restart. I restart and there is no SVN support. The software installer knows its there because I can't reinstall it without uninstalling it. So the questions: Why isn't the plugin/feature loading for the SVN Team Support? Is there a checkbox that I forgot about that enables the plugin? Is there a command line option that will force reload all of the features on the disk? I've tried to install other things like findbugs, but I get the same result. I have no messages in the log file indicating an exception or anything like that.

  • About Interview structure for test automation lab developers

    - by Ikaso
    Hi, I am interviewing new applicants for a team that is doing test automation on our company product(s). The team is composed of junior software developers and a team leader. The product runs on windows and has both managed and unmanaged parts. The test automation is done on both client side (user mode and kernel mode) and server side (IIS, Windows Services, backend). We are doing mainly intergration tests and black box tests. I am trying to figure out how to organize my interview. My overall idea is to ask about a project they have done, then ask some technical questions (multithreading, GC, design patterns) and one programming question. Please note that there is another interview done before me with 2 programming questions. My programming question is rather simple (for example: reversing a singly-linked linked list). My coworkers think that my questions will not find good developers since my questions are rather simple and well known, but so far most of the applicants fail those questions. My questions are: Should I change the structure of my interview for this kind of job? What questions do you ask to figure our if the applicant is test oriented? (Maybe I should provide a buggy implementation of a problem and let them find the bugs and then ask them about what tests they would have done) Regards,

  • rails 4 -- working with js format from ajax

    - by user101289
    I'm still working on learning Rails, and I have a page with team information that will get updated based on a team's icon click, which fires an ajax call to the controller to populate some tabs. I've read some good info about how to use format.js in the controller to render a partial from a js.coffee or js.erb file. The problem I'm running into is in the coffeescript I think. Right now, I'm getting some data called @schedules from the controller, and passing it to a schedule.js.coffee file that should populate a partial for each record returned and attach it to a table. // schedule.js.coffee $.each @schedules, (schedule) -> ($ '#schedule_data').append("<%= j render(partial: 'schedules/schedule', locals: { s: schedule }) %>") This throws an error `> undefined local variable or method `schedule' for #<#<Class:0x007fe535cd2900>:0x007fe535d32a30>` I tried simplifying the coffeescript to just log the output: $.each @schedules, (schedule) -> console.log(schedule) but this prints nothing. Am I missing something? I am very inexperienced with coffeescript, but it seems like I should be getting some data-- I verified that the schedule items do exist for this team item.

  • Should a developer write their own test plan for Q/A?

    - by Mat Nadrofsky
    Who writes the test plans in your shop? Who should write them? I realize developers (like me) regularly do their own unit testing whilst developing and in some cases even their own Q/A depending on the size of the shop and the nature of the business, but in a big software shop with a full development team and Q/A team, who should be writing those official "my changes are done now" test plans? Soon, we'll be bringing on another Q/A member to our development team. My question is, going forward, is it a good practice to get your developers to write their own test plans? Something tells me that part of that might make sense but another part might not... What I like about that: Developer is very familiar with the changes made, thus it's easy to produce a document... What I don't like about that: Developer knows how it's supposed to work and might write a test plan that caters to this without knowing it. So, with the above in mind, what is the general stance on this topic? I'm of course already reading books like the Mythical Man-Month, Code Complete and a few others which really do help, but I'd like to get some input from the group as well.

  • Rails: Added new Action in Controller, but there is no path?

    - by Newbie
    Hello! I try to do following: A user is on his profile page. Now he edits his profile. He klicks on update and the data is saved. Now I want to redirect the user to another kind of profile-edit-page. I did the following in my users_controller.rb: def update @user = User.find(params[:id]) respond_to do |format| if @user.update_attributes(params[:user]) flash[:notice] = 'User was successfully updated.' if(@user.team_id != nil) format.html { redirect_to(@user) } else format.html { redirect_to choose_team_path } end format.xml { head :ok } else format.html { render :action => "edit" } format.xml { render :xml => @user.errors, :status => :unprocessable_entity } end end end def choose_team @user = User.find(params[:id]) end I created a view: /users/choose_team.html.erb Now I get the following error: undefined local variable or method `choose_team_path' for #<UsersController:0x1f56650> So I added choose_team to my routes.rb: map.choose_team 'choose-team', :controller => 'users', :action => 'choose_team' Now, after submitting my first edit form, it redirects me to http://localhost:3000/choose-team and I get following error: Couldn't find User without an ID What I want: If a user has no team_id, he should be redirected to my choose_team.html.erb for choosing a team, else he should be redirected to his profile/show. How to do this?
