• How to monitor a folder for changes, and execute a command if it does, on Windows?

  - by Camilo Martin

  There are similar questions for Linux and Mac, but I'm after a Windows solution here. The problem is as follows: I want to write several (js) script files in a folder, and have a program monitor that folder for file changes and new files being added, and run a command whenever that happens (to compile them all into one single file). The solution has to: Monitor both file changes and new files being added, in a folder. Run a command only if there is any change. It would be best if it either is a built-in solution (like a JScript or VBscript snippet), or something that does not require installation.

• How would one run a task sequence within a task sequence in SCCM 2012 SP1

  - by BigHomie

  A Shining Example: Inside all of my task sequences I have a group that installs driver packages conditionally based on computer model: And of course, this list does nothing but grow. The fact that it grows isn't a big deal, what is a big deal is that every time it changes I have to manually copy and paste those changes across every task sequence I have, which of course leaves huge room for human error. The same goes for other groups of tasks that are common across task sequences. Looking for a solution where I could centrally manage these tasks, be it link other task sequences to a group within another task sequence, or create a separate task sequence and link to that. I came across a solution by John Marcum (SCCM MVP) that mentioned this ability, but this was a while ago and I can't find the link to it anymore to see if it's even still being updated/maintained, but I'm looking for more of a free solution, or even using Powershell or the ConfigMgr SDK is fine with me, I'm no stranger to either.

• Build vs Rebuild

  - by prash

  Build means compile and link only the source files that have changed since the last build, while Rebuild means compile and link all source files regardless of whether they changed or not. Build is the normal thing to do and is faster. Sometimes the versions of project target components can get out of sync and rebuild is necessary to make the build successful. In practice, you never need to Clean. Build or Rebuild Solution builds or rebuilds all projects in the your solution, while Build or Rebuild <project name> builds or rebuilds the StartUp project. To set the StartUp project, right click on the desired project name in the Solution Explorer tab and select Set as StartUp project. The project name now appears in bold. Compile just compiles the source file currently being edited. Useful to quickly check for errors when the rest of your source files are in an incomplete state that would prevent a successful build of the entire project. Ctrl-F7 is the shortcut key for Compile. All source files that have changed are saved when you request a build/rebuild, so you don't have to save them first. When you run your executable (F5 or Ctrl-F5), Visual Studio saves all your changed source files and builds anything that changed, so you don't need to explicitly do those steps every time. This allows for quick "trial and error" debugging. Incidentally, if you like those little Visual Studio keyboard shortcuts, you can download posters of the C# and the VB.Net ones, respectively (I am personally a big fan of using keyboard shortcuts :) ).   Visual Studio 2010 http://www.microsoft.com/downloads/en/details.aspx?FamilyID=92ced922-d505-457a-8c9c-84036160639f   Visual Studio 2005 C#: http://www.microsoft.com/downloads/details.aspx?FamilyID=c15d210d-a926-46a8-a586-31f8a2e576fe&DisplayLang=en VB.NET: http://www.microsoft.com/downloads/details.aspx?FamilyID=6bb41456-9378-4746-b502-b4c5f7182203&DisplayLang=en

• Is StackOverflow making me stupid? [closed]

  - by Ayush Goyal

  Possible Duplicate: When stuck, how quickly should one resort to Stack Overflow? Its good that solution to almost every programming problem is available at my disposal, either someone has asked it before or programming gurus are waiting for me to post it..sometimes its just the matter of seconds after posting the question and someone points out the error-causing-line or proposes alternate (easier, lightweight and efficient) solution. But today it struck me "is this making me dumb?" In good (umm..not so good) old days I used to figure out the source of my problem and then work it out myself, though it used to eat up lot of time but it helped in developing my logical thinking as it used to make an impression in my mind due to which I tend to avoid that situation in future codes. Now, as soon as I encounter a problem I just give it a shot or two and head towards the community. Many times after looking at the solution it turns out that answer was all in front of me..all I needed was to take a break, hover it once and its solved. Both the approaches make me feel guilty, for wasting time when I could have asked and solved it within minutes OR being too lazy to look over it again before posting the code snippet.

• I need an approach to the problem of preventing inserting duplicate records into the database

  - by Maurice

  Apologies is this question is asked on the incorrect "stack" A webservice that I call returns a list of data. The data from the webservice is updated periodically, so a call to the webservice done in one hour could return the same data as a call done in an hour. Also, the data is returned based on a start and end date. We have multiple users that can run the webservice search, and duplicate data is most likely to be returned (especially for historical data). However I don't want to insert this duplicate data in the database. I've created a db table in which the data is stored (most important columns are) Id int autoincrement PK Date date not null --The date to which the data set belongs. LastUpdate date not null --The date the data set was last updated. UserName varchar(50) --The name of the user doing the search. I use sql server 2008 express with c# 4.0 and visual studio 2010. Entity Framework is used as the ORM. If stored procedures could be avoided in the proposed solution, then that will be a plus. Another way of looking interpreting what I'm asking a solution for is as follows: I have a million unique records in my table. A user does a new search. The search results from the user contains around 300k of the data that is already in the db. An efficient solution to finding an inserting only the unique records is needed.

• Where can I find design exercises to work on?

  - by Oak

  I feel it's important to continue practicing my problem-solving skills. Writing my own mini-projects is one way, but another is to try and solve problems posted online. It's easy to find interesting programming quizzes online that require applying clever algorithms to solve - Project Euler is one well-known example. However, in a lot of real-life projects the design of the software - especially in the initial phases - has a large impact and at later stages it cannot be tweaked as easily as plain algorithms. In order to improve these skills, I'm looking for any collection of design problems. When I say "design", I mean the abstract design of a software solution - for example what modules will there be and what are the dependencies between them, how data will flow in the program, what sort of data needs to be saved in the database, etc. Design problems are those problems that are critical to solve in the early stages of any project, but their solution is a whiteboard diagram without a single line of code. Of course these sort of problems do not have a single correct solution, but I'll be especially happy with any place that also displays pros and cons of the typical solutions that might be used to approach the problem.

• What is a good way to share internal helpers?

  - by toplel32

  All my projects share the same base library that I have build up over quite some time. It contains utilities and static helper classes to assist them where .NET doesn't exactly offer what I want. Originally all the helpers were written mainly to serve an internal purpose and it has to stay that way, but sometimes they prove very useful to other assemblies. Now making them public in a reliable way is more complicated than most would think, for example all methods that assume nullable types must now contain argument checking while not charging internal utilities with the price of doing so. The price might be negligible, but it is far from right. While refactoring, I have revised this case multiple times and I've come up with the following solutions so far: Have an internal and public class for each helper The internal class contains the actual code while the public class serves as an access point which does argument checking. Cons: The internal class requires a prefix to avoid ambiguity (the best presentation should be reserved for public types) It isn't possible to discriminate methods that don't need argument checking   Have one class that contains both internal and public members (as conventionally implemented in .NET framework). At first, this might sound like the best possible solution, but it has the same first unpleasant con as solution 1. Cons: Internal methods require a prefix to avoid ambiguity   Have an internal class which is implemented by the public class that overrides any members that require argument checking. Cons: Is non-static, atleast one instantiation is required. This doesn't really fit into the helper class idea, since it generally consists of independent fragments of code, it should not require instantiation. Non-static methods are also slower by a negligible degree, which doesn't really justify this option either. There is one general and unavoidable consequence, alot of maintenance is necessary because every internal member will require a public counterpart. A note on solution 1: The first consequence can be avoided by putting both classes in different namespaces, for example you can have the real helper in the root namespace and the public helper in a namespace called "Helpers".

• Are injectable classes allowed to have constructor parameters in DI?

  - by Songo

  Given the following code: class ClientClass{ public function print(){ //some code to calculate $inputString $parser= new Parser($inputString); $result= $parser->parse(); } } class Parser{ private $inputString; public __construct($inputString){ $this->inputString=$inputString; } public function parse(){ //some code } } Now the ClientClass has dependency on class Parser. However, if I wanted to use Dependency Injection for unit testing it would cause a problem because now I can't send the input string to the parser constructor like before as its calculated inside ClientCalss itself: class ClientClass{ private $parser; public __construct(Parser $parser){ $this->parser=$parser; } public function print(){ //some code to calculate $inputString $result= $this->parser->parse(); //--> will throw an exception since no string was provided } } The only solution I found was to modify all my classes that took parameters in their constructors to utilize Setters instead (example: setInputString()). However, I think there might be a better solution than this because sometimes modifying existing classes can cause much harm than benefit. So, Are injectable classes not allowed to have input parameters? If a class must take input parameters in its constructor, what would be the way to inject it properly? UPDATE Just for clarification, the problem happens when in my production code I decide to do this: $clientClass= new ClientClass(new Parser($inputString));//--->I have no way to predict $inputString as it is calculated inside `ClientClass` itself. UPDATE 2 Again for clarification, I'm trying to find a general solution to the problem not for this example code only because some of my classes have 2, 3 or 4 parameters in their constructors not only one.

• VMware9 fails to launch Virtual OS. Ubuntu 12.10 64bit (Unable to change virtual machine power state: Pipe connection has been broken.)

  - by pst007x

  Another issue I need help with. I use VMware for work on Ubuntu 12.04. However for some reasons my VMware Workstation software generates the following error: Unable to change virtual machine power state: Failed to power on '/home/pst007x/vmware/Windows 7 x64/Windows 7 x64.vmx'. Transport (VMDB) error -14: Pipe connection has been broken. Product: VMware® Workstation Version: 9.0.0 build-812388 Host OS Version: 3.5.0-18-generic Ubuntu 12.10 64bit Kernel Linux 3.5.0-18-generic I have seen patches, but nothing works, and the patches are not maintained, broken links. PLEASE NOTE: I know that this has been asked, but there was no answer given that resolves this issue. Unfortunately I have changed all my office and personal PC's to Ubuntu, and use Win7 in a vm, however since 12.10, vm now fails to launch. For me this is a catastrophe, and makes Ubuntu useless for me to use! I am in a desperate situation here, is there is anyone that can offer any help I would be truly appreciative. I have looked on the VMware forums and the only solution is offered for Fedora, but the people posting there are not clear about what the solution is! thanks PLEASE DO NOT CLOSE THIS QUESTION! I have tried everywhere to find a solution, but I have come up blank... Patches referenced to in other posts do not work in this version of VMware...

• Name of the Countdown Numbers round problem - and algorithmic solutions?

  - by Dai

  For the non-Brits in the audience, there's a segment of a daytime game-show where contestants have a set of 6 numbers and a randomly generated target number. They have to reach the target number using any (but not necessarily all) of the 6 numbers using only arithmetic operators. All calculations must result in positive integers. An example: Youtube: Countdown - The Most Extraordinary Numbers Game Ever? A detailed description is given on Wikipedia: Countdown (Game Show) For example: The contentant selects 6 numbers - two large (possibilities include 25, 50, 75, 100) and four small (numbers 1 .. 10, each included twice in the pool). The numbers picked are 75, 50, 2, 3, 8, 7 are given with a target number of 812. One attempt is (75 + 50 - 8) * 7 - (3 * 2) = 813 (This scores 7 points for a solution within 5 of the target) An exact answer would be (50 + 8) * 7 * 2 = 812 (This would have scored 10 points exactly matching the target). Obviously this problem has existed before the advent of TV, but the Wikipedia article doesn't give it a name. I've also saw this game at a primary school I attended where the game was called "Crypto" as an inter-class competition - but searching for it now reveals nothing. I took part in it a few times and my dad wrote an Excel spreadsheet that attempted to brute-force the problem, I don't remember how it worked (only that it didn't work, what with Excel's 65535 row limit), but surely there must be an algorithmic solution for the problem. Maybe there's a solution that works the way human cognition does (e.g. in-parallel to find numbers 'close enough', then taking candidates and performing 'smaller' operations).

• Add entire 300 GB filesystem to Git Annex repository?

  - by Ryan Lester

  By default, I get an error that I have too many open files from the process. If I lift the limit manually, I get an error that I'm out of memory. For whatever reason, it seems that Git Annex in its current state is not optimised for this sort of task (adding thousands of files to a repository at once). As a possible solution, my next thought was to do something like: cd / find . -type d | git annex add --$NONRECURSIVELY find . -type f | git annex add # Need to add parent directories of each file first or adding files fails The problem with this solution is that there doesn't seem from the documentation to be a way to non-recursively add a directory in Git Annex. Is there something I'm missing or a workaround for this? If my proposed solution is a dead end, are there other ways that people have solved this problem?

• Microsoft Outlook 2007 - General Failure. The URL was: "<http:/something.com>". The parameter is incorrect

  - by Simon Peverett

  For the last two days, Outlook has decided it doesn't like URL's. Any email message that comes in containing an URL will show the following in an error dialogue message box when I click on the link: General Failure. The URL was: "http:/something.com/somewhere/". The parameter is incorrect If I copy the link into a browser, it works correctly. OS is Windows XP SP 3, Microsoft Office 2007 (Outlook), Internet Explorer 8 (also Chrome). I have, of course, Googled this and the two most popular solutions are: Solution 1: Add/Remove programs Set Program Access and Defaults Custom tab Make sure a default browser is selected Solution 2: Add/Remove Programs Select the MS Office 2007 item Click Change Click Repair I have tried both of these and I still get the problem. Has anyone else had this problem and solved it with a solution other than those listed above?

• Learning a new concept - write from scratch or use frameworks?

  - by Stu

  I have recently been trying to learn about MVVM and all of the associated concepts such as repositories, mediators, data access. I made a decision that I would not use any frameworks for this so that I could gain a better understanding of how everything worked. I’m beginning to wonder if that was the best idea because I have hit some problems which I am not able to solve, even with the help of Stack Overflow! Writing from scratch I still feel that you have a much better understanding of something when you have been in the guts of it than if you were at a higher level. The other side of that coin is that you are in the guts of something that you don't fully understand which will lead to bad design decisions. This then makes it hard to get help because you will create unusual scenarios which are less likely to occur when you working within the confines of a framework. I have found that there are plenty of tutorials on the basics of a concept but very few that take you all the way from novice to expert. Maybe I should be looking at a book for this? Using frameworks The biggest motivation for me to use frameworks is that they are much more likely to be used in the workplace than a custom rolled solution. This can be quite a benefit when starting a new job if it's one less thing you have to learn. I feel that there is much better support for a framework than a custom solution which makes sense; many more people are using the framework than the solution that you created. The level of help is much wider as well, from basic questions to really specific, detailed questions. I would be interested to hear other people's views on this. When you are learning something new, should you/do you use frameworks or not? Why? If it's a combination of both, when do you stop one and move on to the other?

• Word 2007 "Out of Memory or Disk Space" Error on launch

  - by Adam

  Word 2007 is installed on a Vista Home Premium machine and whenever it starts up it opens what appears to be a dynamic installer to do something and then throws up the "Out of Memory or Disk Space" error. Word 2007 never completes starting up. Reinstalling Word hasn't helped and if I can avoid reinstalling Windows until Windows 7 is released and get Word working in the mean time, that would be ideal. I've been looking around for a solution, once of which seemed to point to a problem with the user account. I created a second user on the machine and Word still had the same problem. The other solution that seems possible is a corrupted normal.dot/normal.dotm file. However, even in the location it should be, I can't seem to find it. Am I going in the right direction with this? Is there another solution I haven't come across that will fix this? If it is possible that renaming normal.dot/normal.dotm how can I find it?

• Is it possible to have a portable plotter that can print QR codes on burlap?

  - by Brian Ballsun-Stanton

  This is a hardware question. Is there a class of plotters that are portable and accept sharpies? The use case: I have a burlap sack. It will be taking very specific potsherds from an archaeological dig. It needs an indelible QR code (or bar code) printed on the burlap. (Stickers have far far too short a lifetime). It was my thought that a plotter that uses sharpies and that works in the field would be the optimal solution for this problem. Is a portable plotter the right solution? If so, who makes them? If not, what is a better solution?

• Tail-recursive implementation of take-while

  - by Giorgio

  I am trying to write a tail-recursive implementation of the function take-while in Scheme (but this exercise can be done in another language as well). My first attempt was (define (take-while p xs) (if (or (null? xs) (not (p (car xs)))) '() (cons (car xs) (take-while p (cdr xs))))) which works correctly but is not tail-recursive. My next attempt was (define (take-while-tr p xs) (let loop ((acc '()) (ys xs)) (if (or (null? ys) (not (p (car ys)))) (reverse acc) (loop (cons (car ys) acc) (cdr ys))))) which is tail recursive but needs a call to reverse as a last step in order to return the result list in the proper order. I cannot come up with a solution that is tail-recursive, does not use reverse, only uses lists as data structure (using a functional data structure like a Haskell's sequence which allows to append elements is not an option), has complexity linear in the size of the prefix, or at least does not have quadratic complexity (thanks to delnan for pointing this out). Is there an alternative solution satisfying all the properties above? My intuition tells me that it is impossible to accumulate the prefix of a list in a tail-recursive fashion while maintaining the original order between the elements (i.e. without the need of using reverse to adjust the result) but I am not able to prove this. Note The solution using reverse satisfies conditions 1, 3, 4.

• Export policy configuration from eTrust ITM 8.1

  - by grub

  Hi everyone. Currently we are using the Enterprise AV Solution eTrust ITM 8.1. The licenses are running out in october and we are going to replace eTrust with another AV solution. The eTrust Server is running on Windows Server 2003 SP2 with an MS SQL 2000 Standard Edition. The problem is that we've got many different policy - sets which we have to redefine in the new AV solution. Is there any way with eTrust ITM 8.1 to export the different policies as csv, pdf ... whatever? I really dont want to do that manually (that would mean one print screen after the other ;-) ) Thank you very much. grub

• How to tell start-stop-daemon to update $HOME and $USER accordingly to --chuid parameter

  - by iElectric

  I'm trying to run a service that uses $HOME and $USER environment variables. I could set them in service itself, but that would only be a temporary solution. Let's say I have a script test.sh with following content: echo $USER And I run it with start-stop-daemon to see my results: $ start-stop-daemon --start --exec `pwd`/test.sh --user guest --group guest --chuid -guest root Seems like it does not update environment, maybe that should be reported as a bug? I have found a nasty hacky solution, which only works (for unknown reason) on my this simple use case: $ start-stop-daemon --exec /usr/bin/sudo --start -- -u guest -i 'echo $USER' guest I'm sure someone else stumbled upon this, I'm interested in clean solution. $ start-stop-daemon --version start-stop-daemon 1.13.11+gentoo

• WordPress mod_rewrite redirect specific folders

  - by Ps Cjef

  As a new user, I'm not allowed to post more than two hyperlinks here. So I have added a space after every http (ignore them and read as full URLs). System: Debian Etch, Apache 2.2 I have a WordPress instance with multiple blogs. I would like to redirect some of the folders based on the year and month, while leaving other folders go to the actual locations. Example: I have archives for a few years, like 2010, 2011 and 2012: http ://mydomain.com/wordpress/myblog/2010/02 http ://mydomain.com/wordpress/myblog/2011/01 http ://mydomain.com/wordpress/myblog/2012/01 I would like to redirect all 2010 and 2011 posts to another blog with the same folder structure: http ://mydomain.com/wordpress/myotherblog/2010/02 http ://mydomain.com/wordpress/myotherblog/2011/01 and so on. I would like to have 2012 and beyond to go to the actual site (http ://mydomain.com/wordpress/myblog/2012/01). I tried mod_rewrite with the following, one rule at a time to test redirection for just one year (and to expand later for other years), and none of them worked! * RewriteEngine is already on since there are some default WordPress rewrites. * RewriteBase is set to http://mydomain.com/wordpress/ . * I put my rule before all the other default WordPress rules are processed. Didn't work solution #1 RedirectMatch 301 /myblog/2010/(.*) /myotherblog/2010/$1 Didn't work solution #2 RewriteRule /myblog/2010/(.*) http ://mydomain.com/myotherblog/2010/$1 [R=301] Didn't work solution #3 RedirectPermanent /myblog/2010/(.*) http ://mydomain.com/myotherblog/2010/$1 I've also tried the above rules with and without a fully qualified URL for the new location. The rewrite log, with log level set to 9, did not provide any useful information. It shows that it looks at the pattern specified against the URL (as mentioned in the rule), but finally what happens is a passthrough to http ://mydomain.com/myblog/ for all URLs or a 500 Internal Server Error. Any ideas on where I could be going wrong or any alternative solutions?

• JEditorPane Code Completion

  - by Geertjan

  Code completion in a JEditorPane: Unfortunately, a lot of this solution depends on the Java Editor support in the IDE. Therefore, to use it, in its current state, you'll need lots of Java Editor related JARs even though your own application probably doesn't include a Java Editor. A key thing one needs to do is implement the NetBeans Code Completion API, using the related tutorial in the NetBeans Platform Learning Trail, but register the CompletionProvider as follows: @MimeRegistration(mimeType = "text/x-dialog-binding", service = CompletionProvider.class) Then in the TopComponent, include this code, which will bind all the completion providers in the above location, i.e., text/x-dialog-binding, to the JEditorPane: EditorKit kit = CloneableEditorSupport.getEditorKit("text/x-java"); jEditorPane1.setEditorKit(kit); FileObject fob; try {     fob = FileUtil.getConfigRoot().createData("tmp.java");     DataObject dob = DataObject.find(fob);     jEditorPane1.getDocument().putProperty(             Document.StreamDescriptionProperty,             dob);     DialogBinding.bindComponentToFile(fob, 0, 0, jEditorPane1);     jEditorPane1.setText("Egypt"); } catch (IOException ex) {     Exceptions.printStackTrace(ex); } Not a perfect solution, a bit hacky, with a high overheard, but a start nonetheless. Someone should look in the NetBeans sources to see how this actually works and then create a generic solution that is not tied to the Java Editor.

• Moving to an outside Exchange provider - How to create new Outlook profile on multiple PCs?

  - by imagodei

  Following an acquisition we are switching from our local Exchange to an outside provider. I need to change account settings / create new profile so that users are able to access their new mailbox, and I hate the idea of doing it manually on every single client. I have tried quick and dirty solution with copying profile information from Registry on one computer to the other, hoping that I could fix user info later. Quite obviously, this didn't work: Outlook recognized the profile, I could select it at the application startup, but there the fun ends - the profile was corrupt. I couldn't change settings in Mail settings on Control panel, either. Didn't find any Group policy solution. Is there any application, script or other solution, that would help me save time commuting from one PC to the other and typing the same info over and over again?

• Backup Solr home

  - by user226188

  I'm new to Solr: I've successfully installed Tomcat and Solr 4.3.1 webapp, and two collections on a CentOS 6.4 machine. Now, my server is in production and I need to make backups of solr. So, I would like to know what is the best way to backup solr... For the moment I'm dooing: stop tomcat = tar of my solr home = start tomcat, but I've read that is not a good solution? Moreover, this implie to stop all the tomcat which have other webapps than solr. I've also heard that there is a script named "backup" in solr home bin's folder ? but my bin folder is empty :( I don't want to make an another slave server with replication, for me it's not a backup solution because my backup are supposed to be send to a bacula backup server all nights. There is no builtin solution that I can work around to make a script ? like a mysqldump for Mysql servers. Thanks for help !

• Why can't WARs share session info?

  - by rvcoutinho

  I have seen several developers looking for a solution for this problem: accessing session information from a different WAR (even when inside the same EAR) - here are some samples: Any way to share session state between different applications in tomcat?, Access session of another web application, different WAR files, shared resources, Tomcat: How to share data between two applications?, What does the crossContext attribute do in Tomcat? Does it enable session sharing? and so on... From all I have searched, there are some specific solutions depending on the container, but it is somehow 'contrary to the specification'. I have also looked through Java EE specification without any luck on finding an answer. Some developers talk about coupling between web applications, but I tend to disagree. What is the reason one would keep WARs inside the same EAR if not coupling? EJBs, for instance, can be accessed locally (even if inside another EJB JAR within the same EAR). More specifically, one of my WARs handles authentication and authorization, and I would like to share this information with other WARs (in the same EAR). I have managed to work around similar problems before by packaging WARs as JARs and putting them into a singular WAR project (WEB-INF/lib). Yet I do not like this solution (it requires a huge effort on servlet naming and so on). And no solution has answered the first (and most important) question: Why can't WARs share session information?

• 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)
