  • Best build dir location to use in Xcode

    - by neoneye
    I'm consolidating my Xcode/TextMate setup and is interested in where you put your build dir. Some years ago I started out having the build dir in the same dir as my xcodeproj file. However it became a mess when my project became a multi project with a applications and frameworks and tests, so I started using ../build as the build dir, so that all the sub projects used the same dir. However Spotlight is indexing this build dir and TextMate's global find is unusable when there is a build dir in the project. I'm thinking either using ~/.build or /build as Xcode's build dir. What build dir do you use and why?

  • Proving the ROI of a technology?

    - by leeand00
    How does one prove the ROI of a technology to their manager? The closest thing I have found to a document on how to do this is: http://www.agilejournal.com/pdf/Finding-ROI-in-Build-Automation.pdf There are formulas in this document, but I can't really tell if they are just alot of marketing or if they are accurate formulas on how to calculate ROI. I'm not really trying to calculate the ROI of the build tool in the above paper, I was just trying to calculate the ROI of a simple build tool like ANT.

  • How does operating system software maintains time clocks?

    - by Neeraj
    Hi everyone, This may sound a bit less relevant but I couldn't think of a better place to ask this question. Now consider this situation, you install an OS on your system, set the timezone and time, do some stuff and turn it off. (Note that there is no power going in to the computer). Now next time (say after some hours or days) you turn it on again, and you see the updated time. How is this possible even when my computer is not connected to the internet and was consuming no power during the period it was down.(Is there some kind of hardware hack?) please clarify!

  • Visual Studio Pre build events and batch set

    - by helloworld922
    Hi, I'm trying to create call a batch file which sets a bunch of environment variables prior to building. The batch file looks something like this (it's automatically generated before-hand to detect ATI Stream SDK or NVidia CUDA toolkit): set OCL_LIBS_X86="%ATISTREAMSDKROOT%libs\x86" set OCL_LIBS_X64="%ATISTREAMSDKROOT%libs\x86_64" set OCL_INCLUDE="%ATISTREAMSDKROOT%include" However, the rest of the build doesn't seem to have access to these variables, so when I try to reference $(OCL_INCLUDE) in the C/C++GeneralAdditional include directories, it will first give me warning that environment variable $(OCL_INCLUDE) was not found, and when I try to include CL/cl.hpp the compile will fail with: fatal error C1083: Cannot open include file: 'CL/cl.hpp': No such file or directory I know that I could put these variables into the registry if I wanted to access them from the visual studio GUI, but I would really prefer not to do this. Is there a way to to get these environment variables to stick after the pre-build events? I can't reference $(ATISTREAMSDKROOT) directly because the project must be able to build for both ATI Stream and NVidia Cuda.

  • Can I create an ASP.NET MVC 2 project with multiple areas without referencing each Child in the pare

    - by No Refunds No Returns
    This is a follow-up question to my original query: http://stackoverflow.com/questions/1791605/how-can-i-use-multiple-projects-to-separate-a-large-asp-net-mvc-site-into-departm Now that I have this working, is there a way to still have multiple project but not have to reference each child area from the parent project? Ideally I'd like to be able to have multiple, separate and distinct projects that only come together on the production/test machines. I should be able to build and test each "area" separately.

  • The Utilization of Software Engineering Development Principles

    - by Chance
    Being a CS student I've had to take a course in basic software engineering. I was a little curious to find such elaborate "software development processes", like the spiral model, the waterfall model, et cetera. Some of these methodologies seem a little antiquated to me and, after speaking with several employed developers, I can't seem to find anyone who actually adheres to these models. Does anyone here have experience working under the guidance of these models? Were they useful to you and your team during the development of your product? Or are these models just some way to communicate a sense of progression to interested parties outside of the development team?

  • Java WebApp - Integrate a Payment method system

    - by spike07
    I've a java webApp where people can sell their items like in ebay. I need to integrate a payment system and I'm wondering what's the best (from a customer point of view) and easiest to integrate in my app. I was thinking to integrate paypal and require all the sellers to have an account on it. Maybe Google Checkout can be a good option as well, but I don't know if it's used a lot. I think I'll redirect the user to Paypal and then remove the item once I receive the confirmation from paypal that the item has been payed. Would you suggest another easier to integrate/more trusted solution? Thank you

  • What scenarios are possible where the VS C# compiler would not compile a reference of a reference?

    - by SuperKing
    Hello, I'm probably asking this question wrong (and that may be why Google isn't helping), but here goes: In Visual Studio I am compiling a C# project (let's call it Project A, the startup project) which has a reference to Project B. Project B has a reference to a Project C, so when A gets built, the dlls for B gets placed in the bin directory of A, as does the dll for C (because B requires C, and A requires B). However, I have apparently made some change recently so that the dll for Project C does not go into the bin directory of Project A when rebuilding the solution. I have no idea what I've done to make this happen. I have not modified the setup of the solution itself, and I have only added additional references to the project files. Code wise, I have commented out most of the actual code in Project B that references classes in Project C, but did not remove the reference from the project itself (I don't think this matters). I was told that perhaps the C# compiler was optimizing somehow so that it was not building Project C, but really I'm out of ideas. I would think someone has run into something similar before Any thoughts? Thanks!

  • How to get the git commit count?

    - by Splo
    I'd like to get the number of commits of my git repository, a bit like SVN revision numbers. The goal is to use it as a unique, incrementing build number. I currently do like that, on Unix/Cygwin/msysGit: git log --pretty=format:'' | wc -l But I feel it's a bit of a hack. Is there a better way to do that? It would be cool if I actually didn't need wc or even git, so it could work on a bare Windows. Just read a file or a directory structure ...

  • System.ServiceModel.CommunicationException on overloading webservice

    - by soldieraman
    I am load testing my webservice and get a System.ServiceModel.CommunicationException when I use 10 threads to communicate to it (without any sleep in between) - basically testing 10 conenctions at a time - through a windows application An error occurred while receiving the HTTP response to http://localhost/XXX/XXXService.asmx. This could be due to the service endpoint binding not using the HTTP protocol. This could also be due to an HTTP request context being aborted by the server (possibly due to the service shutting down). See server logs for more details. Why would this happen and how to best resolve it

  • What tools to use to build large java commercial projects ?

    - by openCage
    There are several tools to build java projects: ant mvn ivy buildr ... From my experience Ant is great for small projects and projects with special build requirements. Mvn is great for large but typical projects without too much special requirements. It also seams better for open source than for commercial projects. What would you recommend in case of large, enterprise, commercial projects ? What do you currently use and what would you rather use and why ?

  • Which tool / technology: System management for databases and dependent services

    - by Filburt
    A follow-up on this system management question: Since I probably will not get much feedback on serverfault I'll give it a try here. My main concern is to reflect the dependencies between the databases, services ans tasks/jobs I'll have to manage. Besides considering Powershell, I even thought about using MSBuild because it would allow for modeling dependencies and reuse configuration targets. In other words: What technology should I use to develop a flexible solution that will allow me to stop service A, B and C on machine D in the right order and disable task E on machine F when taking down database X?

  • System.XML or Regex.Replace?

    - by cam
    I'm generating a large amount of XML documents from a set of values in an Excel file. The only thing that changes for each XML document is the values. I figured the best way to generate these documents was to make a "XML skeleton" (since the XML format never changes) and then plug in symbols like "&%blahNameblahTest", so then I could just preform a Regex.Replace on each value. I will be handing over this project to another developer and I'm wondering if I should convert the project to generate the XML file manually everytime through the System.XML namespace. The only advantages I see to this is ensuring that the XML document is valid. The current method would be more readable than that method, and way faster since I'm generating around 1500 documents.

  • Algorithm for Source Control System?

    - by Michael Stum
    I need to write a simple source control system and wonder what algorithm I would use for file differences? I don't want to look into existing source code due to license concerns. I need to have it licensed under MPL so I can't look at any of the existing systems like CVS or Mercurial as they are all GPL licensed. Just to give some background, I just need some really simple functions - binary files in a folder. no subfolders and every file behaves like it's own repository. No Metadata except for some permissions. Overall really simple stuff, my single concern really is how to store only the differences of a file from revision to revision without wasting too much space but also without being too inefficient (Maybe store a full version every X changes, a bit like Keyframes in Videos?)

  • C functions invoked as threads - Linux userland program

    - by Einar
    I'm writing a linux daemon in C which gets values from an ADC by SPI interface (ioctl). The SPI (spidev - userland) seems to be a bit unstable and freezes the daemon at random times. I need to have some better control of the calls to the functions getting the values, and I was thinking of making it as a thread which I could wait for to finish and get the return value and if it times out assume that it froze and kill it without this new thread taking down the daemon itself. Also I could do other things like resetting the ADC before restarting. Is this possible? Pseudo example of what I want to achieve: (function int get_adc_value(int adc_channel, float *value) ) pid = thread( get_adc_value(1,&value); //makes thread wait_until_finish(pid, timeout); //waits until function finishes/timesout if(timeout) kill pid, start over //if thread do not return in given time, kill it (it is frozen) else if return value sane, continue //if successful, handle return variable value and continue Thanks for any input on the matter, examples highly appreciated!

  • How can I find file system concurrency issues ?

    - by krosenvold
    I have an application running on Linux, and I find myself wanting windows (!). The problem is that every 1000 times or so I run into concurrency problems that are consistent with concurrent reading/writing of files. I am fairly sure that this behavior would be prohibited by file locking under Windows, but I don't have any sufficiently fast windows box to check. There is simply too much file access (too much data) to expect strace to work reliably - the sheer volume of output is likely to change the problem too. It also happens on different files every time. Ideally I would like to change/reconfigure the linux file system to be more restrictive (as in fail-fast) wrt concurrent access. Are there any tools/settings I can use to achieve this ?
