  • Which software do you use for SCRUM ?

    - by Rahul Soni
    I checked wikipedia, http://en.wikipedia.org/wiki/Scrum_(development) But I am still looking for some insight from the genius minds using SO. I installed Microsoft Project 2010, and was assuming that it would have some template/plugin that would support SCRUM. Unfortunately, I couldn't find one :-(

  • Options to develop professionally with Microsoft tools and Technologies without spending a lot?

    - by iama
    I would like to develop applications for the Windows platform & at the very least I need a server based Windows OS (2008), SQL Server, IIS and Visual Studio. Looks like VS2010 professional alone will cost over $1K. Is there a cheaper option to get hold of Microsoft software? I remember long time ago there was an MSDN subscription option which allowed user access to server based OS and other server applications with restrictive licensing that was cost effective. I don't see that option anymore. Moreover, I am not a student & I understand Microsoft provides software at discounted rates for students. Any pointers? Many thanks.

  • DBMS for POS software

    - by Andrew Smith
    Hello, I want to develop a POS application in .NET (C#) that would be used to rent items. I have a good idea of what will be done and the famous question that I have is about the DBMS that I should use. I would like to use MySQL database. The question is: If some places use only one computer (no network, no internet connection), can I use a MySQL database in local? Do I need to install MySQL server on all thoses computers to be able to use such a database? I know SQLite but I'm not sure if the limitations can cause problems in the future... I also looked at SQLServer Express versions. (I must consider that other point of sales are using multiple computers and more transactions so there I can't put sqlexpress or sqlite) So can anybody suggest me what I should do in that situation? Thanks

  • software/languages for online structured data collection from (human) clients

    - by Ben
    I need to develop a web interface to collect and validate a range of data from many of my organization's clients. This isn't a single form, but a collection of forms with interdependencies (i.e., field X on form Y is needed if field A was equal to C on form B), and variable length lists (please provide the details for all Xs in your possession). I had a look at the marketing on Microsoft InfoPath and Adobe LiveCycle, but I get the impression that they're principally electronic forms solutions rather than data collection tools. (e.g., If a user has entered their address once, they should never have to see it on a form again). Any suggestions of good tools, applications or domain-specific languages?

  • Dependency Injection and decoupling of software layers

    - by cs31415
    I am trying to implement Dependency Injection to make my app tester friendly. I have a rather basic doubt. Data layer uses SqlConnection object to connect to a SQL server database. SqlConnection object is a dependency for data access layer. In accordance with the laws of dependency injection, we must not new() dependent objects, but rather accept them through constructor arguments. Not wanting to upset the DI gods, I dutifully create a constructor in my DAL that takes in SqlConnection. Business layer calls DAL. Business layer must therefore, pass in SqlConnection. Presentation layer calls Business layer. Hence it too, must pass in SqlConnection to business layer. This is great for class isolation and testability. But didn't we just couple the UI and Business layers to a specific implementation of the data layer which happens to use a relational database? Why do the Presentation and Business layers need to know that the underlying data store is SQL? What if the app needs to support multiple data sources other than SQL server (such as XML files, Comma delimited files etc.) Furthermore, what if I add another object upon which my data layer is dependent on (say, a second database). Now, I have to modify the upper layers to pass in this new object. How can I avoid this merry-go-round and reap all the benefits of DI without the pain?

  • How do you implement Software Transactional Memory?

    - by Joseph Garvin
    In terms of actual low level atomic instructions and memory fences (I assume they're used), how do you implement STM? The part that's mysterious to me is that given some arbitrary chunk of code, you need a way to go back afterward and determine if the values used in each step were valid. How do you do that, and how do you do it efficiently? This would also seem to suggest that just like any other 'locking' solution you want to keep your critical sections as small as possible (to decrease the probability of a conflict), am I right? Also, can STM simply detect "another thread entered this area while the computation was executing, therefore the computation is invalid" or can it actually detect whether clobbered values were used (and thus by luck sometimes two threads may execute the same critical section simultaneously without need for rollback)?

  • Advice for Architecture Design Logic for software application

    - by Prasad
    Hi, I have a framework of basic to complex set of objects/classes (C++) running into around 500. With some rules and regulations - all these objects can communicate with each other and hence can cover most of the common queries in the domain. My Dream: I want to provide these objects as icons/glyphs (as I learnt recently) on a workspace. All these objects can be dragged/dropped into the workspace. They have to communicate only through their methods(interface) and in addition to few iterative and conditional statements. All these objects are arranged finally to execute a protocol/workflow/dataflow/process. After drawing the flow, the user clicks the Execute/run button. All the user interaction should be multi-touch enabled. The best way to show my dream is : Jeff Han's Multitouch Video. consider Jeff is playing with my objects instead of the google maps. :-) it should be like playing a jigsaw puzzle. Objective: how can I achieve the following while working on this final product: a) the development should be flexible to enable provision for web services b) the development should enable easy web application development c) The development should enable client-server architecture - d) further it should also enable mouse based drag/drop desktop application like Adobe programs etc. I mean to say: I want to economize on investments. Now I list my efforts till now in design : a) Created an Editor (VB) where the user writes (manually) the object / class code b) On Run/Execute, the code is copied into a main() function and passed to interpreter. c) Catch the output and show it in the console. The interpreter can be separated to become a server and the Editor can become the client. This needs lot of standard client-server architecture work. But some how I am not comfortable in the tightness of this system. Without interpreter is there much faster and better embeddable solution to this? - other than writing a special compiler for these objects. Recently learned about AXIS-C++ can help me - looks like - a friend suggested. Is that the way to go ? Here are my questions: (pl. consider me a self taught programmer and NOT my domain) a) From the stage of C++ objects to multi-touch product, how can I make sure I will develop the parallel product/service models as well.? What should be architecture aspects I should consider ? b) What technologies are best suited for this? c) If I am thinking of moving to Cloud Computing, how difficult/ how redundant / how unnecessary my efforts will be ? d) How much time in months would it take to get the first beta ? I take the liberty to ask if any of the experts here are interested in this project, please email me: [email protected] Thank you for any help. Looking forward.

  • What's the best self-tracking software for Linux?

    - by trench
    I'm looking for a way to track myself and receive quality data upon which I can write future scripts/programs. For example, I use Google Reader a lot. I'd like to track the hrefs that garner my clicks. Further, I'd like to drop all of the words of each href into a database where they can be stacked in a hierarchical manner. At the end of the week I want to know that "Ubuntu" garnered 448 clicks and "Cheetos" garnered 2. :) That's just one example... I'd like this tracking and data-collecting to extend beyond my browser. I know writing something to do this myself wouldn't be too awfully difficult but if something already exists I'd happily use it. Thanks in advance. Primary OS: Ubuntu 10.04

  • How to write software for my touchpad?

    - by Nona Urbiz
    I have some ideas for improvements on my touchpad, ranging from the run of the mill scroll horizontally at the bottom, tapzones for right click, to more complicated ones. But I have no idea where to get started? I'm working on Windows 7 Home Premium, its an Asus laptop, and I have none of these options natively available to me. Regardless, I want to write something that anyone can use. Where would I start? (it'd be nice to write in c++? is that possible? what are the requirements here? what language would be recommended?)

  • Which distribution website should I pick for my open-source package?

    - by Frank
    I wrote an open-source software package, which I'd like to publish (using Apache 2 license). I see various options for how/where to publish/host it: Get my own domain and put it there Put it on Sourceforge Put it on Google Code Put it on Freshmeat ...? What are your experiences / recommendations? What's the current trend among software developers? My only requirements are that I ... can add my own logo on the website can put up some documentation there, get a nice URL that is easy to remember get SVN support (I would also be fine with just uploading a tarball for each new version, it just shouldn't force me to use CVS or any other version control system I'm not familiar with) and of course, the site shouldn't take ownership in the code etc. oh, and it should be free (ok, for registering my own domain I'll be willing to pay a little bit)

  • 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!

  • How do I move from being a software developer to being a software architect?

    - by Nestor
    I mean... Should I start programming less and designing more? Should I stop reading programming books, and start reading more books about pattern designs, etc? Should I stop focusing primarily on Microsoft technologies and open up my horizons with other technologies (in order to get a broader perspective)? How should I change my mind set in general (perhaps less detail oriented) ? etc I'm looking for concrete advice, especially from your own experience!

  • Advice on software / database design to avoid using cursors when updating database

    - by Remnant
    I have a database that logs when an employee has attended a course and when they are next due to attend the course (courses tend to be annual). As an example, the following employee attended course '1' on 1st Jan 2010 and, as the course is annual, is due to attend next on the 1st Jan 2011. As today is 20th May 2010 the course status reads as 'Complete' i.e. they have done the course and do not need to do it again until next year: EmployeeID CourseID AttendanceDate DueDate Status 123456 1 01/01/2010 01/01/2011 Complete In terms of the DueDate I calculate this in SQL when I update the employee's record e.g. DueDate = AttendanceDate + CourseFrequency (I pull course frequency this from a separate table). In my web based app (asp.net mvc) I pull back this data for all employees and display it in a grid like format for HR managers to review. This allows HR to work out who needs to go on courses. The issue I have is as follows. Taking the example above, suppose today is 2nd Jan 2011. In this case, employee 123456 is now overdue for the course and I would like to set the Status to Incomplete so that the HR manager can see that they need to action this i.e. get employee on the course. I could build a trigger in the database to run overnight to update the Status field for all employees based on the current date. From what I have read I would need to use cursors to loop over each row to amend the status and this is considered bad practice / inefficient or at least something to avoid if you can??? Alternatively, I could compute the Status in my C# code after I have pulled back the data from the database and before I display it on screen. The issue with this is that the Status in the database would not necessarily match what is shown on screen which just feels plain wrong to me. Does anybody have any advice on the best practice approach to such an issue? It helps, if I did use a cursor I doubt I would be looping over more than 1000 records at any given time. Maybe this is such small volume that using cursors is okay?

  • Algorithmic trading software safety guards

    - by Adal
    I'm working on an automatic trading system. What sorts of safe-guards should I have in place? The main idea I have is to have multiple pieces checking each other. I will have a second independent little process which will also connect to the same trading account and monitor simple things, like ensuring the total net position does not go over a certain limit, or that there are no more than N orders in 10 minutes for example, or more than M positions open simultaneously. You can also check that the actual open positions correspond to what the strategy process thinks it actually holds. As a bonus I could run this checker process on a different machine/network provider. Besides the checks in the main strategy, this will ensure that whatever weird bug occurs, nothing really bad can happen. Any other things I should monitor and be aware of?

  • Install .exe software application on remote machines.

    - by coral_reef
    Hi, I modified this script from the net, which is suppose to install .exe applications for remote machines: $m = Read-Host "Enter machine name" $File = "c:\temp\office2007sp2-kb958194-fullfile-en-us.exe" $product = [WMICLASS]"\$m\ROOT\CIMV2:win32_Process" $product.Create($File) When I run this script, I have noticed that this program promptly creates a process in the remote machine with the application name office2007sp2-kb958194-fullfile-en-us.exe. This can be checked in the task manager also. But other than that, there is no way to find out if this is getting installed in the remote machine or not. Is there a way to find out, if the installation is really happening? Or does this script actually works? Any help will be great! Reagrds Arindam

  • Installing software on Solaris

    - by sturda
    I'd like to install several unix utilities (incl. xmlstarlet, wget) on a solaris 10 machine which I don't have root access to (obviously, I have a user account). I'm not that experienced with solaris and am wondering if I can simply get hold of an uber binary for each utility I need and just place this in my home directory? Is this feasible? Many thanks
