• How would I prevent users from logging in a PC while software is installing?

  - by user333121

  So I currently am looking for a solution to keeping users logged out while software is installing or activating a pop-up message that cannot be moved, closed, and is always on top, because sometimes when we deploy software to users (via SCCM), the parameters of the install require the user to be logged out for the duration of the installation. I've looked at trying to customize the group policy for account lockout but with no luck. Anyone know of any programs or scripts that do this? Thank you!

• How do I stop Gimp from autolaunching on startup?

  - by Joshua Fox

  Gimp launches every time I log into Xubuntu (v. 13.10). Gimp is not shown under Settings Manager- Sessions and startup. It does not appear in ~/.config/autostart. I immediately close Gimp in these cases, so it is not running when I shut down the session. How do I stop Gimp from autolaunching on startup? Diagnostic Info: Note that cd / find . -name gimp.desktop Only produces ./usr/share/applications/gimp.desktop and nothing else Here is the output of grep -lIr 'gimp' ~/ ~/Gimp-search-results.txt sbin/vgimportclone home/joshua/.gimp-2.8/controllerrc home/joshua/.gimp-2.8/tags.xml home/joshua/.gimp-2.8/dockrc home/joshua/.gimp-2.8/gimprc home/joshua/.gimp-2.8/themerc home/joshua/.gimp-2.8/templaterc home/joshua/.gimp-2.8/gtkrc home/joshua/.gimp-2.8/sessionrc home/joshua/.gimp-2.8/toolrc home/joshua/.gimp-2.8/pluginrc home/joshua/.gimp-2.8/menurc home/joshua/Gimp-search-results.txt home/joshua/.local/share/ristretto/mime.db home/joshua/.wine/drive_c/windows/system32/gecko/1.4/wine_gecko/dictionaries/en-US.dic home/joshua/.wine/drive_c/windows/syswow64/gecko/1.4/wine_gecko/dictionaries/en-US.dic home/joshua/.cache/software-center/piston-helper/rec.ubuntu.com,api,1.0,recommend_app,skype,,0495938f41334883bd3a67d3b164c1d1 home/joshua/.cache/software-center/piston-helper/rec.ubuntu.com,api,1.0,recommend_app,gnome-utils,,91bba9b826fb21dbfc3aad6d3bd771cb home/joshua/.cache/software-center/piston-helper/rec.ubuntu.com,api,1.0,recommend_app,icedtea-plugin,,7bb5e4ad0469ef8277032c048b9d7328 home/joshua/.cache/software-center/piston-helper/reviews.ubuntu.com,reviews,api,1.0,review-stats,any,any,,1c66e24123164bb80c4253965e29eed7 home/joshua/.cache/software-center/piston-helper/rec.ubuntu.com,api,1.0,recommend_app,wine1.4,,2bac05a75dcec604ee91e58027eb4165 home/joshua/.cache/software-center/piston-helper/software-center.ubuntu.com,api,2.0,applications,en,ubuntu,saucy,amd64,,32b432ef7e12661055c87e3ea0f3b5d5 home/joshua/.cache/software-center/apthistory.p home/joshua/.cache/software-center/reviews.ubuntu.com_reviews_api_1.0_review-stats-pkgnames.p home/joshua/.cache/oneconf/861c4e30b916e750f16fab5652ed5937/package_list_861c4e30b916e750f16fab5652ed5937 home/joshua/.cache/sessions/xfwm4-23e853443-fb4b-42fd-aa61-33fa99fdc12c.state home/joshua/.cache/sessions/xfce4-session-athena:0 home/joshua/.config/abiword/profile

• I'm tasked with leading the documentation effort for an existing, entirely undocumented, software product - what resources are there to help me?

  - by Ben Rose

  I'm a software developer at a technology company. I have been tasked with leading the documentation effort for the product I work on. The goal is to produce documentation internal to developer, and the project spills over into the business side, where it covers requirements documentation. This project is challenging. Specifically, I'm dealing with a product which: - has been around for a long time, at least 6 years. - has no form of documentation other than some small, outdated pieces here and there. - has comments in the code, but they are technical and do not convey any over-arching behavior (even on technical side). - as a consequence of having little to no documentation, is often unnecessarily complex under the covers In addition, we have not been given a lot of time to work on this project. I do not have any formal documentation or writing background, training, or experience. I have displayed some ability in writing/communication around the office, which may be why I was assigned to this project. Please share your advice or recommendation for resources to help me prepare and deal with this project. I'm looking for references to books/website/forums/whatever, to help me come up with the design of a plan with milestones, learn about best practices, task delegation, templates, buy-in, etc. I'm hoping specifically for resources targeting or giving special mention of introducing good documentation to existing, undocumented, projects. I would be very grateful for your responses. Ben

• System halts for a fraction of second after every 2-3 seconds

  - by iSam

  I'm using Windows 7 on my HP ProBook 4250s. The problem I face is that my system halts for a fraction of second after every 2-3 seconds. These jerks are not letting me concentrate or work properly. This happens even when I'm just typing in notepad while no other application is running. I tried to install every driver from HP's website and there's no item in device manager marked with yellow icon. Following are my system specs: Machine: HP ProBook 4250s OS: Windows 7 professional RAM: 2GB Processor: Intel Core i3 2.27GHz Following is my HijackThis Log: **Logfile of HijackThis v1.99.1** Scan saved at 9:34:03 PM, on 11/13/2012 Platform: Unknown Windows (WinNT 6.01.3504) MSIE: Internet Explorer v9.00 (9.00.8112.16450) **Running processes:** C:\Windows\system32\taskhost.exe C:\Windows\System32\rundll32.exe C:\Windows\system32\Dwm.exe C:\Windows\Explorer.EXE C:\Windows\System32\igfxtray.exe C:\Windows\System32\hkcmd.exe C:\Windows\System32\igfxpers.exe C:\Program Files\Synaptics\SynTP\SynTPEnh.exe C:\Program Files\PowerISO\PWRISOVM.EXE C:\Program Files\AVAST Software\Avast\AvastUI.exe C:\Program Files\Free Download Manager\fdm.exe C:\Windows\system32\wuauclt.exe C:\Program Files\Windows Media Player\wmplayer.exe C:\Program Files\Microsoft Office\Office12\WINWORD.EXE C:\HijackThis\HijackThis.exe R1 - HKCU\Software\Microsoft\Internet Explorer\Main,Search Page = http://go.microsoft.com/fwlink/?LinkId=54896 R0 - HKCU\Software\Microsoft\Internet Explorer\Main,Start Page = http://bing.com/ R1 - HKLM\Software\Microsoft\Internet Explorer\Main,Default_Page_URL = http://go.microsoft.com/fwlink/?LinkId=69157 R1 - HKLM\Software\Microsoft\Internet Explorer\Main,Default_Search_URL = http://go.microsoft.com/fwlink/?LinkId=54896 R1 - HKLM\Software\Microsoft\Internet Explorer\Main,Search Page = http://go.microsoft.com/fwlink/?LinkId=54896 R0 - HKLM\Software\Microsoft\Internet Explorer\Main,Start Page = http://go.microsoft.com/fwlink/?LinkId=69157 R0 - HKLM\Software\Microsoft\Internet Explorer\Search,SearchAssistant = R0 - HKLM\Software\Microsoft\Internet Explorer\Search,CustomizeSearch = R0 - HKCU\Software\Microsoft\Internet Explorer\Toolbar,LinksFolderName = R3 - URLSearchHook: (no name) - {7473b6bd-4691-4744-a82b-7854eb3d70b6} - (no file) O2 - BHO: Adobe PDF Reader Link Helper - {06849E9F-C8D7-4D59-B87D-784B7D6BE0B3} - C:\Program Files\Common Files\Adobe\Acrobat\ActiveX\AcroIEHelper.dll O2 - BHO: Babylon toolbar helper - {2EECD738-5844-4a99-B4B6-146BF802613B} - (no file) O2 - BHO: MrFroggy - {856E12B5-22D7-4E22-9ACA-EA9A008DD65B} - C:\Program Files\Minibar\Froggy.dll O2 - BHO: avast!

• How to facilitate code reviews in a small team for embedded software?

  - by Adam Lewis

  Short Question Does a cost-effective tool / workflow exist to facilitate code reviews in a small team? More specifically, a small team that relies on post-commit code reviews. Background Our team currently consists of 3 full time and 1 part time software engineers, with plans on hiring more in the near future. Due to our team size and volume of projects we all must juggle, the pre-commit workflow that major tools (such as Review Board and Code Collaborator) use is not obtainable for us right now. The best we can do at the moment is to perform post-commit reviews before major releases or as time permits. Nearly all of our projects are hosted on RepositoryHosting.com (which I highly recommend) and contain a mixture of SVN and GIT repositories. Current Thoughts Since I cannot find a tool that fits our needs right now, I am turning to TRAC that is built into our repository's site. At the moment we use TRAC to file tickets and track milestones, so to me this seems like a natural fit for code review results as well. The direction I am heading in right now is to use a spread sheet(s) to log all of the bugs and comments. Do some macro magic to get it in a format that I can use TRAC's import ticket method and use TRAC's ticketing system to create the action items / bug reports automatically. The auto ticket generation is darn near a must have, adding in bugs and comments one at a time from a web-gui is really painful. Secondary Question If this workflow makes sense, is there a good / standard template to use as a code review log?

• Development-led security vs administration-led security in a software product?

  - by haylem

  There are cases where you have the opportunity, as a developer, to enforce stricter security features and protections on a software, though they could very well be managed at an environmental level (ie, the operating system would take care of it). Where would you say you draw the line, and what elements do you factor in your decision? Concrete Examples User Management is the OS's responsibility Not exactly meant as a security feature, but in a similar case Google Chrome used to not allow separate profiles. The invoked reason (though it now supports multiple profiles for a same OS user) used to be that user management was the operating system's responsibility. Disabling Web-Form Fields A recurrent request I see addressed online is to have auto-completion be disabled on form fields. Auto-completion didn't exist in old browsers, and was a welcome feature at the time it was introduced for people who needed to fill in forms often. But it also brought in some security concerns, and so some browsers started to implement, on top of the (obviously needed) setting in their own preference/customization panel, an autocomplete attribute for form or input fields. And this has now been introduced into the upcoming HTML5 standard. For browsers that do not listen to this attribute, strange hacks* are offered, like generating unique IDs and names for fields to avoid them from being suggested in future forms (which comes with another herd of issues, like polluting your local auto-fill cache and not preventing a password from being stored in it, but instead probably duplicating its occurences). In this particular case, and others, I'd argue that this is a user setting and that it's the user's desire and the user's responsibility to enable or disable auto-fill (by disabling the feature altogether). And if it is based on an internal policy and security requirement in a corporate environment, then substitute the user for the administrator in the above. I assume it could be counter-argued that the user may want to access non-critical applications (or sites) with this handy feature enabled, and critical applications with this feature disabled. But then I'd think that's what security zones are for (in some browsers), or the sign that you need a more secure (and dedicated) environment / account to use these applications. * I obviously don't deny the ingeniosity of the people who were forced to find workarounds, just the necessity of said workarounds. Questions That was a tad long-winded, so I guess my questions are: Would you in general consider it to be the application's (hence, the developer's) responsiblity? Where do you draw the line, if not in the "general" case?

• What is an elegant way to install non-repository software in 12.04?

  - by Tomas

  Perhaps I missed something when Canonical removed the "Create launcher" option from the right click menu, because I've really been missing that little guy. For me, it was the preferred way to install software that comes not in a .deb, but in a tar.gz, for example. (Note: in that tar.gz I have a folder with the compiled files, I'm NOT compiling from source) I just downloaded the new Eclipse IDE and extracted the tar.gz to my /usr folder. Now, I'd like to add it to my desktop and dash so it can be started easily. Intuitively I would right click the desktop and create a launcher. After this I'd copy the .desktop to /usr/share/applications. However, creating a launcher is not possible. My question: How would you install an already compiled tar.gz that you have downloaded from the internet? Below are a few things I've seen, but these are all more time-consuming than the right click option. If you have any better ideas, please let me know. Thanks! Manual copy & create a .desktop file: manually Simply extract the archive to /usr. Create a new text file, adding something along the lines of the code block below: [Desktop Entry] Version=1.0 Type=Application Terminal=false Exec="/usr/local/eclipse42/eclipse" Name="Eclipse 4.2" Icon=/home/tomas/icons/eclipse.svg Rename this file to eclipse42.desktop and make it executable. Then copy this to /usr/share/applications. Manually copy & create a .desktop file: GUI fossfreedom has elaborated on this in How can I create launchers on my desktop? Basically it involves the command: gnome-desktop-item-edit --create-new ~/Desktop After creating the launcher, copy it to /usr/share/applications.

• How should I determine my rates for writing custom software?

  - by Carson Myers

  For a custom software that will likely take a year or more to develop, how would I go about determining what to charge as a consultant? I'm having a hard time coming up with a number, and searches online are providing vastly different numbers (between $55/hr and $300/hr). I don't want to shoot too low because it's going to take me so much time (and I'm deferring my education for this project). I also don't want to shoot too high and get unpleasant looks and demand for justification. FWIW I live in Canada, and have approx. 10 years of development experience. I've read the "take your salary and divide it by 1000" rule of thumb, but the thing is I don't have a salary. Currently I'm just doing fairly small programming tasks for a friend who is starting a marketing company, pricing each task fairly arbitrarily. I don't know what I would make over the course of a year doing it, but it would be incredibly low. My responsibilities for the project would be the architecture, programming, database, server, and UX to some degree. It's going to be a public facing web service so I will also need to put a lot of effort into security and scalability. Any advice or experience?

• Software development process for a part time University project for 1 developer?

  - by Pricey

  I will be doing a part time University project soon and the time frame for it is around 8 months with approximately 10-15 hours a week spent working on it, with a review by a tutor each quarter. My question is what software development process would you recommend using when the course requires you to work on your own in order to manage yourself as well as the project? I wanted to use a weekly or bi-weekly iterative approach to my work but a lot of the processes seem tailored to teams of people. I am looking at XP (Extreme Programming) OR Scrum as something that is less than the norm for University work but again Scrum I don't know a lot about yet, and a question I have is; can you say you are doing XP without pair-programming? because my tutor seems to think that I have to stick to all the practices otherwise I can't do it (nevermind if I am working alone). We can have external user input as well but due to the small timescales with part time work it may be more beneficial for myself to be the user as well, which is not what I prefer considering how I can get lost in the design.

• "System.Data.OracleClient requires Oracle client software version 8.1.7 or greater." Error Message

  - by Jandost Khoso

  Quick resolution: Give full permission to AUTHENTICATED USERS in following folders. a) ORACLE_HOME b) Program Files\ORACLE   Check your PATH. You might have installed different clients in your system and your .NET application is pointing to a home with inappoperiate client. What your .NET application should load is OCI.DLL with File version more than 8.1.7. According to the MSDN document Oracle and ADO.NET:   "The .NET Framework Data Provider for Oracle provides access to an Oracle database using the Oracle Call Interface (OCI) as provided by Oracle Client software. The functionality of the data provider is designed to be similar to that of the .NET Framework data providers for SQL Server, OLE DB, and ODBC. "     The MSDN document System Requirements (Oracle) says: "The .NET Framework Data Provider for Oracle requires Microsoft Data Access Components (MDAC) version 2.6 or later. MDAC 2.8 SP1 is recommended. You must also have Oracle 8i Release 3 (8.1.7) Client or later installed. "   Both the .NET Framework Data Provider for Oracle and Oracle Data Provider for .NET are data providers to access Oracle database. The former ships with .NET Framework and requires Oracle client version 8.1.7 or above. The latter is provided by Oracle company and requires Oracle client version 9.2 or later.     The Oracle Data Provider for .NET (ODP.NET) features optimized ADO.NET data access to the Oracle database. ODP.NET allows developers to take advantage of advanced Oracle database functionality, including Real Application Clusters, XML DB, and advanced security.   See the document Comparing the Microsoft .NET Framework 1.1 Data Provider for Oracle and the Oracle Data Provider for .NET for more information about the difference.

• Would it be possible to create an open source software library, entirely developed and moderated by an open community?

  - by Steven Jeuris

  Call it democratic software development, or open source on steroids if you will. I'm not just talking about the possibility of providing a patch which can be approved by the library owner. Think more along the lines of how Stack Exchange works. Anyone can post code, and through community moderation it is cleaned up and eventually valid code ends up in the final library. For complex libraries an elaborate system should probably be created, but for a simple library it is my belief this is already possible even within the Stack Exchange platform. Take a library of extension methods for .NET for example. Everybody goes their own way and implements their own subset of what they feel is important, open-source library or not. People want to share their code, but there is no suitable platform for it. extensionmethod.net is the result of answering this call for extension methods, but the framework hopelessly falls short; there is no order, or structure at all. You don't know whether an idea is any good until you try it, so I decided to create an Extension Methods proposal on Area51. I belief with proper moderation, it could be possible for the site to be more than a Q&A site, and that an actual library (or subsets of it) could be extracted from it. Has anything like this been attempted before? Are there platforms better suited for this?

• Is it correct to fix bugs without adding new features when releasing software for system testing?

  - by Pratik

  This question is to experienced testers or test leads. This is a scenario from a software project: Say the dev team have completed the first iteration of 10 features and released it to system testing. The test team has created test cases for these 10 features and estimated 5 days for testing. The dev team of course cannot sit idle for 5 days and they start creating 10 new features for next iteration. During this time the test team found defects and raised some bugs. The bugs are prioritised and some of them have to be fixed before next iteration. The catch is that they would not accept the new release with any new features or changes to existing features until all those bugs fixed. The test team says that's how can we guarantee a stable release for testing if we also introduce new features along with the bug fix. They also cannot do regression tests of all their test cases each iteration. Apparently this is proper testing process according to ISQTB. This means the dev team has to create a branch of code solely for bug fixing and another branch where they continue development. There is more merging overhead specially with refactoring and architectural changes. Can you agree if this is a common testing principle. Is the test team's concern valid. Have you encountered this in practice in your project.

• What are the options for retraining formally as a software engineer?

  - by Matt Harrison

  I'm a self-taught programmer. I have a good undergraduate degree in Architecture (building, not software). I was always a science/maths kid and got consistency good grades in these subjects. However I became indecisive at undergraduate level and switched between Physics, Chemistry, Art and finally stuck with Architecture mainly out of the desperate need to finish any degree. As soon as I graduated, I ditched architecture and started writing code again professionally. I've been a programmer now for 3 years and I've progressed very quickly. I'm ambitious and I want to work for the top companies in this field at some point and I've realised I need a Computer Science education to be taken seriously (based on job ads for the big tech firms). I've applied for a few MSc programs in Computer Science but they've all rejected me because of my BA. It's just not an option for me to quit my job and go back and do another 3 year undergraduate degree in CS. I know I can study at this level because I've read most of the books on the reading lists for CS courses in the UK that I can find and I have this knowledge now, it's just I can't prove it on an application form. What options are available to me?

• How long should I keep 301 redirecting pages from a deprecated domain?

  - by ElHaix

  I had an old domain that I have deprecated, but 301 redirected all results from it to my new site. The new site is now receiving a decent amount of traffic, but I don't know if it's 301 redirected from the old site, and doing a site:[old site] still shows several thousand pages indexed. Since all pages from the old site are 301 redirected, will they ever be removed from the index, as long as the old domain name is active? As a rule of thumb, somewhere I got 90 days for any significant site changes. When is it safe to burn the old domain?

• Will proprietary software-based sound enhancements work with Ubuntu? (BeatsAudio, Dolby)

  - by LiveWireBT

  This question is targeted at mainstream or gamer-grade software-based audio/sound enhancements, found in highly integrated computing and entertainment systems like laptops, tablets and smartphones. These are mostly marketed with fancy badges of known audio-releated brands on the product or packaging, while being mostly uncertain about the actual implementation or components used and poorly differentiated from the general audio capabilities of the system or device. This question is not about actual hardware like speakers. If your headphones are not properly detected, your speakers are assigned wrong, work partially or not at all then your soundcard or chip is not properly detected and you should take a look at troubleshooting audio issues. This question is also not about enthusiast or recording-grade hardware like recording interfaces, amplifiers and DACs in a variety of formfactors. And this question is also not about audio encoding and playback of different audio formats like Dolby Digital, Dolby TrueHD and DTS. Most of these may be subject to patents and licensing, see restricted formats. If you are just searching for an equalizer, please take a look at this question: Is there any Sound enhancers/equalizer? Simply speaking: Every feature where you would flip a switch or check a box in a fancy looking interface in Windows that makes the sound change from neutral to fancy.

• Can it be a good idea to lease a house rather than a standard office-space for a software development shop? [closed]

  - by hamlin11

  Our lease is up on our US-based office-space in July, so it's back on my radar to evaluate our office-space situation. Two of our partners rather like the idea of leasing a house rather than standard office-space. We have 4 partners and one employee. I'm against the idea at this moment in time. Pros, as I see them Easier to get a good location (minimize commutes) All partners/employees have dogs. Easier to work longer hours without dog-duties pulling people back home More comfortable bathroom situation Residential Internet Rate Control of the thermostat Clients don't come to our office, so this would not change our image The additional comfort-level should facilitate a significantly higher-percentage of time "in the zone" for programmers and artists. Cons, as I see them Additional bills to pay (house-cleaning, yard, util, gas, electric) Additional time-overhead in dealing with bills (house-cleaning, yard, util, gas, electric) Additional overhead required to deal with issues that maintenance would have dealt with in a standard office-space Residential neighbors to contend with The equation starts to look a little nasty when factoring in potential time-overhead, especially on issues that a maintenance crew would deal with at a standard office complex. Can this be a good thing for a software development shop?

• My game seems to be incompatible with recording software. What could be causing this?

  - by Lewis Wakeford

  I've just finished a little Game-Dev project for university and I need to record a video to accompany my submission (just in case they can't get my source to work). Basically my game doesn't work at all when FRAPS or Bandicam attempts to attach to it, I get a black screen and a stream of GL INVALID OPERATION messages from my error reporting code. Dxtory can't seem to hook into it correctly at all, it doesn't display it's FPS counter or anything. My game logic appears to be running correctly from the debug traces, it just seems like all the gl library calls break. I don't know a huge amount about how these programs operate so I don't really know what I could be doing to cause this. I've heard they read from the OpenGL frame buffers so maybe I'm doing something wrong there? I'm letting GLFW and GLEW do all the low level initialization, but I have successfully recorded projects with the same setup and recording software. Essentially, has anyone ever run into something like this before or do you know anything about how these programs work that could give a clue as to the cause of the issue?

• Any empirical evidence on the efficacy of CMMI?

  - by mehaase

  I am wondering if there are any studies that examine the efficacy of software projects in CMMI-oriented organizations. For example, are CMMI organizations more likely to finish projects on time and/or on budget than non-CMMI organizations? Edit for clarification: CMMI stands for "Capability Maturity Model Integration". It's developed by the Software Engineering Institute at Carnegie-Mellon University (SEI-CMU). It's not a certification, but there are various companies that will "appraise" your organization to various levels of CMMI, such as level 2 and level 3. (I believe CMMI level 1 is an animalistic, Hobbesian free-for-all that nobody aspires to. In other words, everybody is at least CMMI level 1, even if you've never heard of CMMI before.) I'm definitely not an expert, but I believe that an organization can be appraised for CMMI levels within different scopes of work: i.e. service delivery, software development, foobaring, etc. My question is focused on the software development appraisal: is an organization that has been appraised to CMMI Level X for software projects more likely to finish a software project on time and on budget than another organization that has not been appraised to CMMI Level X? However, in the absence of hard data about software-oriented CMMI, I'd be interested in the effect that CMMI appraisals have on other activities as well. I originally asked the question because I've seen various studies conducted on software (e.g. the essays in The Mythical Man Month refer to numerous empirical studies, as does McConnell's Code Complete), so I know that there are organizations performing empirical studies of software development.

• Is there a massive other side to software development which I've somehow missed, revolving entirely around Microsoft?

  - by Aerovistae

  I'm still a beginning programmer; I've been at it for 2 years. I've learned to work with a few languages, a bit of web development technologies, a handful of libraries, frameworks, and IDEs. But over the past two years (and long before I even started, really), I keep hearing references to these...things. A million of them. Things such as C#, ADO, SOAP, ASP, ASP.NET, the .NET framework, CLR, F#, etc etc. And I've read their Wikipedia articles, in-depth, multiple times, and they all mention a million other things on that list, but I just can't seem to grasp what it all is. The only thing I've taken away with any certainty is that Microsoft is behind all of it. It sounds almost like a conspiracy. Are all these technologies just for developing on the Windows platform? What is .NET? Do some software developers dedicate their entire career just to that side of things? Why would I want to get into it, and what advantage does...whatever it is...have over all the other technologies there are? I hope this makes sense. It's a broad question, but inside it there's a very specific question asking about something I don't know the name of. Hopefully you can grasp my confusion.

• Why is a software development life-cycle so inefficient?

  - by user87166

  Currently the software development lifecycle followed in the IT company I work at is: The "Business" works with a solution manager to build a Business Requirement document The solution manager works with the Program manager to build a Functional Spec The PM works with the engineering lead to develop a release plan and with the engineering team to develop technical specifications If there are any clarifications required, developers contact the PM who contacts the solution manager who contacts the business and all the way back introducing a latency of nearly 24 hours and massive email chains for any clarifications By the time the tech spec is made, nearly 1 month has passed in back and forth Now, 2 weeks go to development while the test writes test cases Code is dropped formally to test, test starts raising bugs. Even if there is 1 root cause for 10 different issues, and its an easily fixed one, developers are not allowed to give fresh code to test for the next 1 week. After 2-3 such drops to test the code is given to the ops team as a "golden drop" ( 2 months passed from the beginning) Ops team will now deploy the code in a staging environment. If it runs stable for a week, it will be promoted to UAT and after 2 weeks of that it will be promoted to prod. If there are any bugs found here, well, applying for a visa requires less paperwork This entire process is followed even if a single SSRS report is to be released. How do other companies process such requirements? I'm wondering why, the business cannot just drop the requirements to developers, developers build and deploy to UAT themselves, expose it to the business who raise functional bugs and after fixing those promote to prod. (even for more complex stuff)

• Is doing AB Tests using site redirection a bad practice?

  - by user40358

  I'm developing hotels websites here in Brazil. When the site is done, we do an AB test with the old version to measure conversion and show to the hotel owner how good our site is. Due to the fact that I cannot put the old site inside the new one as a subresource (newone.com/old), currently I'm doing those AB test as follows: 1) I create 2 Google Analytics accounts, one for each site (old and new); 2) I put the GA tags in the old website pages (changing its possibly existent GA ID to the just created one); 3) I put an Javascript code that redirects the user to the old website (in a different URL and different domain) with 50% of probability. So I compare all the metrics, events and goals between those two GA accounts. How bad is it? How Google can interpretate the fact of being, sometimes redirected, sometimes don't? The experiment usually runs for 2 weeks. Is there any other alternative for doing this in a better way?

• Grub gives messages about the boot sector being used by other software. What should I do?

  - by Bobble

  This only happens with one of my computers. It is an elderly laptop that has had a long and varied history with several operating systems, but in its retirement it is acting as a server for my home network using Ubuntu 12.04. It is a single-boot system, there are no other systems installed. Every so often, whenever there is a grub upgrade, I notice a message like this: Setting up grub-common (1.99-21ubuntu3.4) ... Installing new version of config file /etc/grub.d/00_header ... Setting up grub2-common (1.99-21ubuntu3.4) ... Setting up grub-pc-bin (1.99-21ubuntu3.4) ... Setting up grub-pc (1.99-21ubuntu3.4) ... /usr/sbin/grub-setup: warn: Sector 32 is already in use by FlexNet; avoiding it. This software may cause boot or other problems in future. Please ask its authors not to store data in the boot track. Installation finished. No error reported. Should I be worried about this? What (if anything) should I do about it?

• What is the best CPU I could get for my old setup?

  - by cmbrnt

  On my current not-so-good desktop computer, I'm currently running an Intel Core 2 Duo E6550-CPU, and I'm thinking of buying a newer one now that these must be cheap on E-bay and the like. Being a software guy, I'd be grateful for any help in identifying what CPUs that would fit my motherboard so I don't buy a processor which won't work with my computer. It might not be worth it however, since the SATA2-drive is currently what's bottlenecking my system, but I'm still curious about what could be done except for buying an SSD-drive. I'm providing screenshots of CPU-Z running, to help with the identification. My CPU- and motherboard info: http://i.imgur.com/YdO8x.png

• Reconciling a new BindingList into a master BindingList using LINQ

  - by Neo

  I have a seemingly simple problem whereby I wish to reconcile two lists so that an 'old' master list is updated by a 'new' list containing updated elements. Elements are denoted by a key property. These are my requirements: All elements in either list that have the same key results in an assignment of that element from the 'new' list over the original element in the 'old' list only if any properties have changed. Any elements in the 'new' list that have keys not in the 'old' list will be added to the 'old' list. Any elements in the 'old' list that have keys not in the 'new' list will be removed from the 'old' list. I found an equivalent problem here - http://stackoverflow.com/questions/161432/ - but it hasn't really been answered properly. So, I came up with an algorithm to iterate through the old and new lists and perform the reconciliation as per the above. Before anyone asks why I'm not just replacing the old list object with the new list object in its entirety, it's for presentation purposes - this is a BindingList bound to a grid on a GUI and I need to prevent refresh artifacts such as blinking, scrollbars moving, etc. So the list object must remain the same, only its updated elements changed. Another thing to note is that the objects in the 'new' list, even if the key is the same and all the properties are the same, are completely different instances to the equivalent objects in the 'old' list, so copying references is not an option. Below is what I've come up with so far - it's a generic extension method for a BindingList. I've put comments in to demonstrate what I'm trying to do. public static class BindingListExtension { public static void Reconcile<T>(this BindingList<T> left, BindingList<T> right, string key) { PropertyInfo piKey = typeof(T).GetProperty(key); // Go through each item in the new list in order to find all updated and new elements foreach (T newObj in right) { // First, find an object in the new list that shares its key with an object in the old list T oldObj = left.First(call => piKey.GetValue(call, null).Equals(piKey.GetValue(newObj, null))); if (oldObj != null) { // An object in each list was found with the same key, so now check to see if any properties have changed and // if any have, then assign the object from the new list over the top of the equivalent element in the old list foreach (PropertyInfo pi in typeof(T).GetProperties()) { if (!pi.GetValue(oldObj, null).Equals(pi.GetValue(newObj, null))) { left[left.IndexOf(oldObj)] = newObj; break; } } } else { // The object in the new list is brand new (has a new key), so add it to the old list left.Add(newObj); } } // Now, go through each item in the old list to find all elements with keys no longer in the new list foreach (T oldObj in left) { // Look for an element in the new list with a key matching an element in the old list if (right.First(call => piKey.GetValue(call, null).Equals(piKey.GetValue(oldObj, null))) == null) { // A matching element cannot be found in the new list, so remove the item from the old list left.Remove(oldObj); } } } } It can be called like this: _oldBindingList.Reconcile(newBindingList, "MyKey") However, I'm looking for perhaps a method of doing the same using LINQ type methods such as GroupJoin<, Join<, Select<, SelectMany<, Intersect<, etc. So far, the problem I've had is that each of these LINQ type methods result in brand new intermediary lists (as a return value) and really, I only want to modify the existing list for all the above reasons. If anyone can help with this, would be most appreciated. If not, no worries, the above method (as it were) will suffice for now. Thanks, Jason

• How can I make the Windows 7 taskbar behave like a cross between the old Quick Launch and new Superbar?

  - by frumious

  I really like the taskbar in Windows 7, I think combining buttons to launch apps and the icons that show your running apps is groovy. However, because I like having as much space as possible, I've got small icons enabled and shrunk the bar down to one row. I've also told it not to group the running apps unless there's no space left (to save me having to work harder to find the particular window I want), which also means that they have captions, and are thus quite wide. The (admittedly small) problem this gives me is that I can pin all my favourite apps to the bar, which looks much like the old Quick Launch bar, but when I launch them the running apps because much wider, and the unlaunched apps get lost amongst them. I can manually change the order to fix this, but next time I'll launch a different app and I'll be back to square one. What I'd prefer is for small unlaunched icons to be kept on the left, and wider running apps to move over to the right, which for me would be the best of both worlds. Is there any way I can organise that? I'm aware that one can use the traditional quick launch bar in Windows 7, but that's not what I'm after; I generally prefer the Windows 7 way.
