• What Does It Usually Mean for a Feature to be "Supported"?

  - by joshin4colours

  I'm currently working some testing for a particular area of an application. I had to write some automated tests for a particular feature but due to the circumstances, this was not easy to do. When I asked one of the other testers about it, he mentioned that the same features exist in a sister application our company produces but isn't documented anywhere (end-user documentation or otherwise). He also said that the feature doesn't typically get tested at all in the sister application and isn't usually tested in the application I work on. Apparently this feature isn't heavily used but removing it would require a fair bit of work so the benefit-cost ratio doesn't work out. All of this has left me with some questions. Other than "The documentation says so" or "We told the client it is", what usually makes a feature "supported" versus an unsupported feature?

• How to get the type of the class for comparison

  - by Halo

  I have this object which is an instance of a superclass. I want to know which subclass that object really is, so that I can decide what to do with it. There is this getClass() method but it's apparently not used for comparison issues. How can I get the sub-type of my object?

• Comparison tool with easy line insertion

  - by Miro Kropacek

  Back in good old days I used to use a tool for file comparison with one incredible feature -- you open file1, file2, see a difference, no magic here. But then you could insert an empty line(s) into file1 with one keyboard combo and into file2 with another keyboard combo. So you could easily adjust how are C / asm function aligned in case diff engine failed to recognize similar stuff. Of course, after the adjust (insertion / removal of one or more lines in either file) whole diff was "recalculated". I fail to find similar feature in diff, KDiff, ... I'd prefer Linux app but I'm OK with Windows app as last resort... Thanks for any hint!

• Generic object comparison diff routine

  - by MicMit

  The question stems from database tables comparison. Let's say we put left row in the instance Left and the right one into instance Right of the same type. And we'got many tables and respective types. How to implement more or less generic routine resulting in a collection of diffs e.g. propertyName , leftValue , rightValue for each such a pair of instances of the same type.

• Side-by-side comparison of data by month in SQL

  - by ScottR

  I have table similar to the following: Year | Product | Value 2006 A 10 2006 B 20 2006 C 30 2007 A 40 2007 B 50 2007 C 60 I would like a query that would return the following comparison Product | 2006 Value | 2007 Value A 10 40 B 20 50 C 30 60 What are the options to do so? Can it be done without joins? I'm working with DB2, but answers in all SQL types would be helpful.

• Is it possible to compute the minimum of three numbers by using two comparisons at the same time?

  - by Milo Hou

  I've been trying to think up of some way that I could do two comparisons at the same time to find the greatest/least of three numbers. Arithmetic operations on them are considered "free" in this case. That is to say, the classical way of finding the greater of two, and then comparing it to the third number isn't valid in this case because one comparison depends on the result of the other. Is it possible to use two comparisons where this isn't the case? I was thinking maybe comparing the differences of the numbers somehow or their products or something, but came up with nothing. Just to reemphasize, two comparisons are still done, just that neither comparison relies on the result of the other comparison. EDIT: what about: boolA = A^2 + B^2 < C^2 boolB = A > B if boolA then max=C else if boolB then max=A else max=B

• Why isn't obliterate an essential feature of Subversion?

  - by Dimitri C.

  For some years now, I'm waiting for Subversion to feature a "delete permanently" (obliterate) function. I hesitate to make the transition to Subversion (coming from Visual SourceSafe :p), because I think this is an essential feature, as otherwise I'd expect the repository to grow unstopably. However, for one reason or the other, the feature gets postponed over and over again. So I begin wondering if there is some other feature or workaround which makes the obliterate function dispensable. What do you do when you want to shrink the SVN central repository? Example 1: I check in a large third party library, and after a few weeks I realize it is not suited for my needs. I don't want that to store and backup that large amount of data forever. Example 2: I have 10 versions of 10 big third party libraries in the repository, but I only use the latest versions. Example 3: I accidentally checked in sensitive information (as suggested by John). Example 4: I accidentally checked in some big files that were never meant to be put in the repository.

• Utility to LOGICALLY compare two xml files?

  - by Matthew

  Right now we are attempting to build golden configurations for our environment. One piece of software that we use relies on large XML files to contain the bulk of its configuration. We want tot ake our lab environment, catalog it as our "golden configuration" and then be able to audit against that configuration in the future. Since diff is bytewise comparison and NOT logical comparison, we can't use it to compare files in this case (XML is unordered, so it won't work). What I am looking for is something that can parse the two XML files, and compare them element by element. So far we have yet to find any utilities that can do this. OS doesn't matter, I can do it on anything where it will work. The preference is something off the shelf. Any ideas? Edit: One issue we have run into is one vendor's config files will occasionally mention the same element several times, each time with different attributes. Whatever diff utility we use would need to be able to identify either the set of attributes or identify them all as part of one element. Tall order :)

• Windows Server 2012 IPAM feature - "Unblock IPAM Access" error/recomended action

  - by HopelessN00b

  So, I'm in the process of setting up an IP Address Management server, using the built-in IPAM feature in Server 2012, and have run into a problem that I'm hoping someone else has successfully solved. Following the technet guide here, I've installed and configured IPAM, and have provisioned it via GPO. After verifying that the PowerShell invoke-ipamgpoprovisioning command is successful, managing the desired servers in IPAM, running gpupdate /force on the servers and refreshing my view in IPAM, I'm still getting the less-than-useful recommended action of "Unblock IPAM Access" for all servers. (First done 3 hours ago, so it's not a give-it-time-to-propagate issue.) Can't, for the life of me, seem to figure out what's causing this, find anything useful in the logs, or find much about this on Google or in the help files, so I was wondering if anyone here had any ideas about how to fix this, or even where to start looking. I'd really like to get this working, because if not, I have to resume work on creating an Excel spreadsheet for IP address management.

• Easy Update "Table of Contents" feature in Microsoft Word 2007 VS. Microsoft word 2010

  - by xarzu

  I am currently working on a document that was written using Microsoft Word 2007 and I am also using Microsoft Word 2007 to update the document. It is just the way of the workplace I am now in. I have noticed that the feature of adding nested headers ("subheaders" perhaps) does not work the same as I remember it did with Microsoft Word 2010. Since I am not the original author of the document, I am not sure if the table of contents was set up the right way. So my first question is: How do I see if the table of contents was set up properly in Microsoft Word 2007 to allow automatic updates whenever a subheader is added to the text. There seems to be a number of other things going on with the document that do not seem right. But maybe if we fix this problem first the other issues will dissolve or be lessened.

• Memory Pressure Protection Feature for TCP Stack - Provided by Microsoft Security Update KB967723

  - by Angry_IT_Guru

  We've been having a lot of funky issues with some of our web based applications that allow clients to submit lot of image files to our servers. Lots of ports are used in the process. http://www.microsoft.com/technet/security/bulletin/MS09-048.mspx - released in Sept-2009. support.microsoft.com/kb/974288 - Memory Pressure Protection description. Evidently, after applying KB967723, our clients receive funky error messages as if connections cannot be made to the server or connections have been closed. There doesn't appear to be a pattern and sometimes it works and other times is doesn't. Typically we've noticed it when server is under load. I'm curious what others think about this MPP and any issues that you may have experienced from it. I understand its purpose, but I think it may have broken a lot of apps in the process. It doesn't look like Microsoft made this "feature" public to everyone.

• Win7 glass-like Aero feature - unable to enable

  - by user24752

  I have a 4 months old PC with Win7 Home Premium x64. Windows Experience Index is 5.4. Intel i5 processor 6GB memory nVidia GT220 video card. During games, Windows reported shortage of system resources, so switched the desktop back to "Windows 7 Basic" desktop theme. After game-over, I could switch back to the normal theme and enjoy all Aero eye-candies. However, lately the glass-like window transparency feature got disabled, and I found no ways to enable it again. There is a Troubleshouting option in Control Panel saying: "Find and fix problems with transparency and other visual effects". If I launch that, it does not find anything. Event viewer is full with the following warnings: The Desktop Window Manager is experiencing heavy resource contention. Scenario : The Desktop Window Manager responsiveness has degraded. Taskbar, window borders, etc, none of the other transparent features work, and I cannot turn them on. Any thoughts?

• Loss of feature set with VMware EVC

  - by Peter

  If I have two machines both 3rd Generation AMD Opteron, one Shanghai & one Istanbul and I can vMotion between them. Does it buy me anything to enable EVC at the 3rd Generation AMD level? Will I lose any CPU features? My thoughts are, I can enable EVC 3rd Generation with running VMs and I can't enable 2nd Generation EVC with running VMs. I figure there won't be a lose in any features because if there was a reduction in feature set then I couldn't enable EVC with running VMs.

• microsoft ergo keyboard 4000 zoom feature

  - by d3020

  This may be an odd question, I apologize. I just got the Microsoft ergo keyboard 4000 and was curious about how the zoom feature was to work. I'm using Windows 7 and in Word, IE, or when viewing an image the zoom doesn't seem to do anything. Device manager says that the drivers are updated. Is there a special key combination that is used to make it work. Not sure what I'm missing with this. Thanks.

• Help desk software - specific feature needed

  - by LunchMoney

  I am having a hard time finding help desk software that allows for drop down hyperlink selection during ticket creation. The situation is that we do external support for client systems and connect via remotely anywhere or logmein. Right now we use a poorly modified php based system that has a customer drop down menu and then a site drop down list that is then parsed by a bit of java script which opens a url. What I am looking for is the ability to store customer site URL information in the database and during the creation of a ticket be able to select the customer name and then select the site there by placing the corresponding site URL in the ticket. The support tech will then be able to click on this link to access the customer's site. Has anyone used or seen help desk software with this feature?

• Wondering how Facebook does the "Mutual friends" feature

  - by Pierre

  Hello, I'm currently developing an application to allow students to manage their courses, and I don't really know how to design the database for a specific feature. The client wants, a lot like Facebook, that when a student displays the list of people currently in a specific course, the people with the most mutual courses are displayed first. As an additional feature, I would like to add a search feature to allow students to search for another one, and displaying first in the search results the people with most mutual courses. I currently use MySQL, I plan to use Cassandra for some other features, and I also use Memcached for result caching. Thanks.

• How-to limit feature functionality

  - by ph0enix

  Are there any standard or "best practice" ways of limiting feature functionality for a particular application? Example: We have a product with a variety of features, and our customers can pick and choose which features they would like to use, and the cost of the product varies based on which features they are actually using. In the past, we have distributed along with our software installer an encrypted license file that contains information about the customer, as well as the collection of features that they have enabled. In code, we read from the license file and enable the functionality according to the license file. This seems to work fine, except there a few disadvantages: Upgrading users with new functionality can be sort of a pain If a particular feature shows up in multiple places throughout the application, a developer might not realize that this feature should be licensed, and forget to check the license file before granting functionality to the user If the license file becomes corrupted, deleted, moved, renamed, etc. the application will not run We're getting ready to roll out a new set of features, and I was just curious what others in the community have done to tackle this problem?
