  • How do you take into account usability and user requirements for your application?

    - by voroninp
    Our team supports BackOffice application: a mix of WinForm and WPF windows. (about 80 including dialogs). Really a kind of a Swiss Army Knife. It is used by developers, tech writers, security developers, testers. The requirements for new features come quite often and sometimes we play Wizard of Oz to decide which GUI our users like the most. And it usually happens (I admit it can be just my subjective interpretation of the reality) that one tiny detail giving the flavor of good usability to our app requires a lot of time. This time is being spent on 'fighting' with GUI framework making it act like we need. And it very difficult to make estimations for this type of tasks (at least for me and most members of our team). Scrum poker is not a help either. Management often considers this usability perfectionism to be a waste of time. On the other hand an accumulated affect of features where each has some little usability flaw frustrates users. But the same users want frequent releases and instant bug fixes. Hence, no way to get the positive feedback: there is always somebody who is snuffy. I constantly feel myself as competing with ourselves: more features - more bugs/tasks/architecture. We are trying to outrun the cart we are pushing. New technologies arrive and some of them can potentially help to improve the design or decrease task implementation time but these technologies require learning, prototyping and so on. Well, that was a story. And now is the question: How do you balance between time pressure, product quality, users and management satisfaction? When and how do you decide to leave the problem with not a perfect but to some extent acceptable solution, how often do you make these decisions? How do you do with your own satisfaction? What are your priorities? P.S. Please keep in mind, we are a BackOffice team, we have neither dedicated technical writer nor GUI designer. The tester have joined us recently. We've much work to do and much freedom concerning 'how'. I like it because it fosters creativity but I don't want to become too nerdy perfectionist.

  • Connect Digest : 2012-07-06

    - by AaronBertrand
    I've filed a few Connect items recently that I think are important. In #752210 , I complain that the documentation for DDL triggers suggests that they can prevent certain DDL from being run, which is not the case at all. http://connect.microsoft.com/SQLServer/feedback/details/752210/doc-ddl-trigger-topic-suggests-that-rollbacks-run-before-action In #745796 , I complain that scripting datetime data in Management Studio yields output that contains a binary representation instead of a human-readable...(read more)

  • What performance indicators can I use to convince management that I need my development PC upgraded?

    - by Aaron Daniels
    At work, my PC is slow. I feel that I can be way more productive if I just wasn't waiting for Visual Studio and everything else to respond. My PC isn't bad (dual-core, 3GB of RAM), but there is a lot of corporate software and whatnot to slow everything down and sometimes lock it up. Now, some developers have begun getting Windows 7 machines with 8 GB of RAM. Of course, I start salivating at this. However, I was told that I "had to justify" why I should get a new machine. I can think of a lot of different things, but I am curious as to what every one else on SO would have to say. NOTE: Ideally, these reasons should be specifically related to .NET development in Visual Studio on a Windows machine. This isn't a "how can I make my machine faster" question.

  • How to separate production and test assets during development?

    - by bcsanches
    Hi Folks, this is like a complement for Assets Management, database or versioning system?. I am wondering about how to separate development, specially programmers assets from production assets? For example, if we keep all the assets on the same repository, how do you keep with programmers assets and final game assets? Do you keep a separate directory for each of those, allowing duplicates? Or do you use some fancy scheme for striping out the "development" and "test" assets from final build?

  • Learn Linux Command Line for Web Server Management [closed]

    - by Jonathan
    I've searched high and low for a good resource for learning the Linux command line. I've found a handful of separate resources, but none that really can assist in web server management. I'm currently learning through trial an error with 'man' pages, along with Google. I was just wondering if anyone had a solid resource that they used to learn, and would be willing to share it with me. Thanks so much for your time, I really appreciate it! EDIT: I have a few CentOS servers at current, and I know the basics, I'm just trying to get to a more advanced level.

  • Managing a Web Portal

    - by A competent translator
    After skimming almost all questions tagged "books" here at Pro Webmasters to find a book on managing web portals I found references to general web mastering. Are there books on managing and curating content of public web portals , i.e. a governmental portal for a given department or agency ? I need a reference on the day-to-day management and best practices of a portal and its content. Also welcomed are references on managing multilingual portals.

  • Expanding list of databases in SQL Server 2008 Management Studio Takes Longer than SQL Server 2005

    - by Clever Human
    Is it just me, or does expanding the list of databases in SQL Server 2008 Management Studio take significantly more time than expanding the list of databases in SQL Server 2005 Management Studio? If it isn't just me, is there an explanation for this behavior? Whatever it is doing in the background that makes it take longer, can we turn that off? Is it configurable? I know, it seems trivial, but I am perpetually being surprised at how long this takes.

  • Buisness Rule and Process Management?

    - by elgcom
    After some searching in google and wikipedia, I still can not get a clear image about the "difference" between BRMS (Business Rule Management System) and BPM (Business process management)/workflow system. can those two concepts do the same thing from each other? (theoretically) A "rule" can be modeled as a "process" as well. isn't it?

  • What is a good metaphor for c memory management?

    - by fsmc
    I'm trying to find a good metaphor to explain memory allocation, initialization and freeing in c to a non technical audience. I've heard pass-by-reference/value talked about quite well with postal service usage, but not so much for allocation/deallocation. So for I've thought about using the idea of renting a space might work, but I wonder if the SO crew can provide something better.

  • I'd like to rebuild my web server without web management software; what knowledge, skills, and tools will I require? [closed]

    - by Joe Zeng
    I've been using Webmin for my web server that runs my personal website and a host of other websites for a while now, and I feel like I should be able to manage my web server more directly, because I haven't even touched the Webmin for the past year or so and I feel like maybe it has too much functionality that I have to click through the next time I want to access it or create a new subdomain or database on my site. I want to try something lighter and more wholly manageable, now that I'm more comfortable with using ssh and command-line tools. I've decided that I'm going to try using Django as a framework, but obviously that's only part of the picture. What sort of knowledge will I require?

  • Mac Management and Security

    - by Bart Silverstrim
    I was going through some literature on managing OS X laptops and asked someone some questions about usage scenarios when using the MacBooks. I asked someone more knowledgeable than I about whether it was possible for my Mac to be taken over if I were visiting another site for a conference or if I went on a wifi network at a local coffee house with policies from an OS X Server with workgroup manager (either legit for the site or someone running a version of OS X Server on hardware they have hidden somewhere on the network), which apparently could be set up to do things like limit my access to Finder or impose other neat whiz-bang management features. He said that it is indeed possible for it to happen as it would be assigned via the DHCP server and the OS X server would assume my Mac is a guest and could hand out restrictions and apparently my Mac will happily accept them without notifying me or giving me an option, unlike Windows which I believe would need to be joined to a domain before it becomes "managed" by Active Directory. So my question is as network admins and sysadmins with users traveling with MacBooks, is there a way to reasonably protect your users from having their machines hijacked without resorting to just turning off networking all the time? Or isn't this much of a security hazard? What threat does this pose to the road warriors in your businesses?

  • BitLocker with Windows DPAPI Encryption Key Management

    - by bigmac
    We have a need to enforce resting encryption on an iSCSI LUN that is accessible from within a Hyper-V virtual machine. We have implementing a working solution using BitLocker, using Windows Server 2012 on a Hyper-V Virtual Server which has iSCSI access to a LUN on our SAN. We were able to successfully do this by using the "floppy disk key storage" hack as defined in THIS POST. However, this method seems "hokey" to me. In my continued research, I found out that the Amazon Corporate IT team published a WHITEPAPER that outlined exactly what I was looking for in a more elegant solution, without the "floppy disk hack". On page 7 of this white paper, they state that they implemented Windows DPAPI Encryption Key Management to securely manage their BitLocker keys. This is exactly what I am looking to do, but they stated that they had to write a script to do this, yet they don't provide the script or even any pointers on how to create one. Does anyone have details on how to create a "script in conjunction with a service and a key-store file protected by the server’s machine account DPAPI key" (as they state in the whitepaper) to manage and auto-unlock BitLocker volumes? Any advice is appreciated.

  • Disabling CPU management

    If I add the following processor.max_cstate=0 to the kernel command line for boot up, does that disable all CPU power management and throttling?

  • Server 2008 Disk Management Hangs

    - by Payson Welch
    So I have looked everywhere for the solution to this and have tried many things. There is one post on SE related to this and I tried the suggested answer but I am still having problems. We have a server running Server 2008 R2 Standard x64. I need to increase the space of C: since the free space is running very low. However when I open Server Manager and try to go to the "Disk Management" snap-in it just hangs. There is a status message on the bottom of the window that says "Connecting to Virtual Disk Service...". Here are the steps I have taken: Ran sfc /scannow Set all of the drives to be dirty and rebooted so that they would be scanned Executed chkdsk /f /r /b /v on all of the drives. Checked for Windows updates (none). Verified that the services "Virtual Disk", "RPC Procedures" and "Plug and Play" are all running. One symptom is that the service "Virtual Disk" does not cleanly shut down. I receive a message about the process being unexpectedly terminated when I try to stop or restart it. Also I cannot find anything relevant in the event logs. Any ideas or suggestions?

    - by Gopinath
    Apple opened the flood gates of iPhone 4S! Now you can buy the unlocked iPhone 4S directly from Apple instead of buying them from grey market. The Apple US Online store has started accepting order for unlocked iPhone 4S and at the moment the expected shipping time is around 1 to 2 weeks. Price of the phones starts from $649 for 16GB and goes up to $849 for 64GB version. These unlocked phones are free from monthly contracts, works on any GSM network around the globe. Sorry CDMA networks, unlocked iPhone 4S is not yet ready for you! Its a good move from Apple. This helps people from staying away from multi-year contracts and also visitors returning from USA now can buy an original unlocked iPhone to use in their home countries.

  • How do developers verify that software requirement changes in one system do not violate a requirement of downstream software systems?

    - by Peter Smith
    In my work, I do requirements gathering, analysis and design of business solutions in addition to coding. There are multiple software systems and packages, and developers are expected to work on any of them, instead of being assigned to make changes to only 1 system or just a few systems. How developers ensure they have captured all of the necessary requirements and resolved any conflicting requirements? An example of this type of scenario: Bob the developer is asked to modify the problem ticket system for a hypothetical utility repair business. They contract with a local utility company to provide this service. The old system provides a mechanism for an external customer to create a ticket indicating a problem with utility service at a particular address. There is a scheduling system and an invoicing system that is dependent on this data. Bob's new project is to modify the ticket placement system to allow for multiple addresses to entered by a landlord or other end customer with multiple properties. The invoicing system bills per ticket, but should be modified to bill per address. What practices would help Bob discover that the invoicing system needs to be changed as well? How might Bob discover what other systems in his company might need to be changed in order to support the new changes\business model? Let's say there is a documented specification for each system involved, but there are many systems and Bob is not familiar with all of them. End of example. We're often in this scenario, and we do have design reviews but management places ultimate responsibility for any defects (business process or software process) on the developer who is doing the design and the work. Some organizations seem to be better at this than others. How do they manage to detect and solve conflicting or incomplete requirements across software systems? We currently have a lot of tribal knowledge and just a few developers who understand the entire business and software chain. This seems highly ineffective and leads to problems at the requirements level.

  • We Found 100 Manufacturing Heros That Focus on Innovation!

    - by Stephen Slade
    There’s a good piece written by Ann Grackin of ChainLink Research on the Manufacturing Leadership 100 Awards program held recently in Palm Beach Fl, Apr 30-May 3, 2012.  This article (link below) highlights the summary of the Summit with specific focus on manufacturing innovation.  There were several informative keynotes and sessions from industrial leaders who are leveraging the latest tools and technologies to make better decisions. Ann writes that she was a panelist with Cindy Reese, SVP, Worldwide Operations, Oracle; and Steven Tungate, VP/GM, Supply Chain & Innovation, Toshiba America Business Solutions about Factories and Supply Networks of the Future. Ann writes “So what are these manufacturers doing? Significant rationalization of the supply base (Toshiba, especially, has this issue since they have a long history of many acquisitions), streamlining production to increase productivity, and looking for lower-cost countries for manufacturing….  No doubt firms have global customer bases, so they need to be present in these markets. However, a low-cost-country manufacturing source does introduce more risk in the supply chain. And that was discussed. Quality, security, and intellectual property protection were the critical global manufacturing issues also discussed. “Cindy (Reese) told a fascinating story about Oracle’s acquisition of Sun and the supply chain that was subsequently created. Here was one of the key points: Although Oracle sells on a global basis, they now do their own factory-installed software. This keeps potential ‘factory-installed malware’ from getting into the servers at contract manufacturers, and prevents pirated software. In this way, Oracle ensures that they deliver the quality and security people expect”.

  • SSRS2008R2 report times out, but the underlying query executes in the Management Studio

    - by Matthew Belk
    A customer of mine recently moved servers and the new server has SQL2008R2. His old server was SQL2005. The new server has substantially better CPU, RAM, and disk performance than the old, but several reports time out while executing. When I run the underlying query in the SQL Management Studio, the query executes in sub-second time. The exact error message returned via the Report Manager UI is: An error occurred within the report server database. This may be due to a connection failure, timeout or low disk condition within the database. (rsReportServerDatabaseError) Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding. It must be noted that this database is not just analytical; it's also fairly transactional, although the transaction volume is not exceptionally high. What can I do to improve the performance of the SSRS query engine? Are there settings in the data source I can adjust, or in the SSRS config files?

  • Microsoft SQL Server Management Studio causing system freeze

    - by CRoshanLG
    I'm experiencing very slow response from MSSMS and it causes other applications to slow down. Specially Skype crashes after few seconds from opening MSSMS, showing an error called "Disk I/O Error". I'm regularly using few applications (Sublime text, MS Word, Firefox, Outlook, Skype and one or two other apps) simultaneously. The system works fine when MSSMS is not in use! But as soon as MSSMS is opened, all the apps start to freeze (MSSMS also responds very slow). This problem has been there for about a week now (I haven't installed any apps or haven't made any changes to the system during that time). -- System Specifications -- Processor: Core i3 (3.1 GHz) RAM: 4 GB OS: Windows 7 Professional (64 bit) Free space in C drive: ~ 100 GB MS SQL Server 2008 R2 Microsoft SQL Server Management Studio version - 10.50.1600.1 I've tried to find a reason for this but there are no helpful information in the web! There are some solutions suggested (in forums and in Skype Support pages) for the Skypes' "Disk I/O Error", all of which I tried but does not solve the problem. Has anyone faced the same senario? (and hopefully) knows a solution? Systems Log I don't have much knowledge in interpreting the System Log, but I think the Critical and Warnings are not helpful. But there are lots of Error logs which might be useful. In source Kernal-General there are few similar errors saying "An I/O operation initiated by the Registry failed unrecoverably.The Registry could not flush hive (file): <some file>" In source atapi also there are few similar errors -- "The driver detected a controller error on \Device\Ide\IdePort0." (all errors has occurred in 'IdePort0') In Application Error, there are several errors logged, and following is the latest one. Both the Errors which has occurred today is similar (to this one). As it is from Ssms.exe, I guess this is relevant to the cause of problem. But as I said above I can't understand what it means!

  • How to achieve a loosely coupled REST API but with a defined and well understood contract?

    - by BestPractices
    I am new to REST and am struggling to understand how one would properly design a REST system to both allow for loose coupling but at the same time allow a consumer of a REST API to understand the API. If, in my client code, I issue a GET request for a resource and get back XML, how do I know what to do with that xml? e.g. if it contains <fname>John</fname><lname>Smith</lname> how do I know that these refer to the concept of "first name", "last name"? Is it up to the person writing the REST API to define in documentation some place what each of the XML fields mean? What if producer of the API wants to change the implementation to be <firstname> instead of <fname>? How do they do this and notify their consumers that this change occurred? Or do the consumers just encounter the error and then look at the payload and figure out on their own that it changed? I've read in REST in Practice that using a WADL tool to create a client implementation based on the WADL (and hide the fact that you're doing a distributed call) is an "anti-pattern". But I was planning to do this-- at least then I would have a statically typed API call that, if it changed, I would know at compile time and not at run time. Why is this a bad thing to generate client code based on a WADL? And how do I know what to do with the links that returned in the response of a POST to a REST API? What defines this contract and gives true meaning to what each link will do? Please help! I dont understand how to go from statically-typed or even SOAP/RPC to REST!
