• How well do (D)VCS cooperate with workflows involving several people editing files in the same direc

  - by frankster

  Imagine because of tradition that your team's preferred development method involved several people with a shared login, editing files on a build server using vim. [Note that there are well known issues to do with only one person being able to edit a file at once, people going away from their desk and leaving the file locked in vim, system builds/restarts requiring everybody to stop debugging while this occurs. This is not what the question is about] If source control was to be introduced without changing the workflow, would there be much benefit? I am guessing that the commit history won't be much use as it will contain all changes by everybody in big lumps. So it wouldn't really be possible to rewind individual changes apart from at a really big level.

• Subclipse CollabNet Myster Icon

  - by Rares Saftoiu

  The scenario is that I'm merging a series of cherry picked revisions from on SVN branch into trunk. I'm using the subclipse CollabNet client to do the merge. Everything works great, except for in addition to the files I picked to merge, my working directory shows a series of changes that svn thinks have changed but that I haven't chosen to merge. If I do a diff on the files in question it tells me there's no differences. If I do a commit, I get the screenshot below, with the mystery icon I haven't been able to find document anywhere. Here's a link to the screenshot: http://i.imgur.com/1a92j.png

• Force Windows to cache executables without running them?

  - by Josh Einstein

  Is there a way to force Windows to pre-load certain EXE/DLL binaries into its prefetch/superfetch cache as if they had been executed? I have a particular application that loads pretty slowly on first run but if it's "warm" (recently executed) it starts pretty quickly. I'd like to prime the cache early in the background before the application is needed. But since it shows a UI, I'm looking for a way to do this silently. So simply launching the application it isn't ideal. Thanks you in advance. Prompted by David's suggestion in the comments, I wrote a PowerShell script to memory map the files, seek to the end, and close them. I haven't done any controlled tests yet and it could just be my imagination, but Sublime Text (the application in question) appeared to load much more quickly this time around and I haven't used it for several hours.

• Setting up a Git remote with a truncated history

  - by drg

  I am in the midst of doing some non-standard, probably doomed, experiments on a git repository. The goal is to create a remote repository with a truncated history which can still share commits with an internal repository which has a full history. I've had some success using a graft to connect the public history with the private history - when I push from my internal repository, only the post-graft contents are included. So my main question is: what is the simplest way of taking a commit, eliminating its parent and writing a graft in place of the parent? A more general question: is what I'm trying to do going to cause me pain in the long run, do you know if there's a better way?

• Nginx + PHP-FPM ignores no-cache headers

  - by Eric Winchell

  I'm using the following header on a php page. // Prevent page caching. header('Expires: Tue, 20 Oct 1981 05:00:00 GMT'); header('Cache-Control: no-store, no-cache, must-revalidate'); header('Cache-Control: post-check=0, pre-check=0', FALSE); header('Pragma: no-cache'); I'm also using a rand=999999999 (with a real random number) in the URLs. But pages are still being cached. Reload works, but first load is cached. Anyone know where I can change this?

• Git: how do you merge with remote repo?

  - by Marco

  Please help me understand how git works. I clone my remote repository on two different machines. I edit the same file on both machines. I successfully commit and push the update from the first machine to the remote repository. I then try to push the update on the second machine, but get an error: ! [rejected] master -> master (non-fast-forward) I understand why I received the error. How can I merge my changes into the remote repo? Do I need to pull the remote repo first?

• Exchange 2007 backup / restore

  - by Matt

  To explain my situation I have a exchange 2007 server and I have recently upgraded to SP2 so that I can use windows server backup to take an "exchange aware" backup of the server. Is there an easy way of restoring this data onto a second server to which I have pre-installed server 2008 / exchange 2007 without upsetting my current exchange server set-up. Also is there a better way to do this, such as running one as a fall over should the primary exchange server develop a fault. I am still new to all this so please excuse any stupidity in my questions. Thanks in advance for any help and assistance

• What's a good unit test framework for Common Lisp projects?

  - by Lorenzo V.

  I need to write a unit test suite for a project I am developing in my spare time. Being a CL newbie I was overwhelmed by the amount of choices for a CL implementation, I spent quite some time to choose one. Now I am facing exactly the same thing with unit test frameworks. A quick glance at http://www.cliki.net/test%20framework shows 20 unit test frameworks! Choice is good but for a novice like me this can be a bit confusing and given the number of frameworks it would be painful to try them all. I would like to use a framework which: Is reasonably well maintained Easy to use but with some degree of flexibility Offers some sort of integration with Emacs (or it is possible to easily integrate it with Emacs) Integration with git post-commit hooks Integration with a continous integration system (such as buildbot) What are your experiences in this field?

• ASP.NET MVC: run code after view has rendered (close db transaction)

  - by thermal7

  Hi, I am using ASP.NET MVC2 with NHibernate, but am facing an issue. All calls to the database via NHibernate should be inside a transaction, however code inside the view kicks off database calls in some instances. Thus there is a need to be able to commit the transaction after the view has rendered. For example displaying a list of users and their user roles you might show the user role using this code: <%: Model.UserRole.Name % This will cause a hit on the database as the UserRole is loaded using a NHibernate proxy. You can fetch the UserRole eagerly which circumvents the issue in this case, but there are cases where it is much faster to use lazy loading. Anyway, is there a way to run code after a view has rendered?

• Why am I seeing excessive disk activity when installing applications?

  - by Kev

  I'm running Windows 7 Ultimate 64 bit on a Dell Vostro 1720 with 8GB of RAM, 7200RPM Disk, 2.53 GHz Core2Duo (Windows 7 64 bit is a supported option and the laptop came with the OS pre-installed). I'm noticing some fairly excessive disk activity when running installers. For example the Visual Studio 2010 RC installer constantly accessed the disk for ~10 minutes. It was so excessive that I was unable to use the machine until this ceased. Today I installed Trillian Astra 4.1 for Windows (latest build from the website). Again when I ran the installer I was pretty much locked out of the machine until the disk activity calmed down. In both cases when I eventually managed to launch task manager I could see that the CPU was sitting at around 5% to 7% utilisation whilst this was going on. All other disk related activity is fine, the machine is snappy and applications launch without delay. It's just when I run an installer I see this odd behaviour. Why would this be?

• PostgreSQL pgdb driver raises "can't rollback" exception

  - by David Parunakian

  Hello, for some reason I'm experiencing the Operational Error with "can't rollback" message when I attempt to roll back my transaction in the following context: try: cursors[instance].execute("lock revision, app, timeout IN SHARE MODE") cursors[instance].execute("insert into app (type, active, active_revision, contents, z) values ('session', true, %s, %s, 0) returning id", (cRevision, sessionId)) sAppId = cursors[instance].fetchone()[0] cursors[instance].execute("insert into revision (app_id, type) values (%s, 'active')", (sAppId,)) cursors[instance].execute("insert into timeout (app_id, last_seen) values (%s, now())", (sAppId,)) connections[instance].commit() except pgdb.DatabaseError, e: connections[instance].rollback() return "{status: 'error', errno:4, errmsg: \"%s\"}"%(str(e).replace('\"', '\\"').replace('\n', '\\n').replace('\r', '\\r')) The driver in use is PGDB. What is fundamentally wrong here?

• Can I import contacts from an Exchange 2003 EDB file for a single user?

  - by Drarok

  We have recently had to reinstall a very unhappy Exchange 2003 server for a client, and whilst rebuilding their server we moved them onto a temporary one. During the course of all this, ExMerge was used due to Windows being so broken that none of the backup software could run. As a number of the user mailboxes were way over 2GB, we had to do date ranges of a few months at a time to avoid ExMerge's 2GB limit. We went back as far as 2006, as the files produced by ExMerge seemed empty that far back. Unfortunately, one of the users has reported that around 2 3rds of their contacts are missing, and that pre-2006 sounds about right for the missing items. Is there any way I can mount the old EDB file into Exchange, or otherwise read their contacts into a usable format? The server is running Windows Server 2003 SBS R2 (SP2), and Exchance 2003 (SP2, I think).

• What is a class outlet and where is it?

  - by chrish

  I am trying to learn iPhone development and someone passed along the website www.appsamuck.com. On Day 1, the tutorial instructs the developer We need to reference the label in our code so we can update the label * In the document window "File's Owner" * Click: Tools->Idenity Inspector * In the inspector click the + under "Class Outlets" * Change myOutlet1 to "countdownLabel" * Change id to UILabel * Click enter to make sure they commit I really don't want to get hung up on this, but I can't find "Class Outlets" either when creating a new project from scratch or opening the zipped source code project. Is this just a difference in versions of Interface Builder? Where did it go?

• Same SCSI drive appears multiple times on the controller list

  - by ohad

  Hi, I have an Adaptec AHA-2940UW SCSI adapter, to which I connected a single Atlas 10K III drive (and nothing more). When my computer loads up, the pre-OS Adaptec screen shows (I believe this is called the POST screen), where I can see the Atlas drive listed many times (i.e. with ID0, ID1, ... ID5, ID7, ID8,...,ID15 [ID6 is the adapter itself]) Using the same HD on an Adaptec AHA-2940UB the disk only shows once Since my OS hasn't been installed yet, I'm not sure if this is a problem (I would guess it is), and if so - how to solve it. Termination and multiple LUNs come mind, but the cable provides termination and I don't see why a hard drive would request multiple LUNs, especially considering it is not jumpered at all, and multuple LUN support is disabled in the Adaptec controller BIOS (via the SCSISelect utility) Thank you

• What guides or standards do you use for version control in your team ?

  - by PaulHurleyuk

  I'm starting to do a small amount of development within my company. I'm intending to use Git for version control, and I'm interested to see what guidelines or standards people are using around version in their groups, similar to coding standards are often written within the group for the group. I'm assuming there will be things like; Commit often (at least every day/week/meeting etc) Release builds are always made from the master branch Prior to release, a new branch will be created for Testing and tagged as such. only bug fixes from this point onwards. The final release of this will be tagged as such and the bug fixes merged back into the trunk Each developer will have a public repo New features should get their own branch Obviously a lot of this will depend on what cvs you're using and how you've structured it.

• Issue with Visual C++ 2010 (Express) External Tools command

  - by espais

  I posted this on SuperUser...but I was hoping the pros here at SO might have a good idea about how to fix this as well.... Normally we develop in VS 2005 Pro, but I wanted to give VS 2010 a spin. We have custom build tools based off of GNU make tools that are called when creating an executable. This is the error that I see whenever I call my external tool: ...\gnu\make.exe): * couldn't commit memory for cygwin heap, Win32 error 487 The caveat is that it still works perfectly fine in VS2005, as well as being called straight from the command line. Also, my external tool is setup exactly the same as in VS 2005. Is there some setting somewhere that could cause this error to be thrown?

• Help with refactoring PHP code

  - by Richard Knop

  I had some troubles implementing Lawler's algorithm but thanks to SO and a bounty of 200 reputation I finally managed to write a working implementation: http://stackoverflow.com/questions/2466928/lawlers-algorithm-implementation-assistance I feel like I'm using too many variables and loops there though so I am trying to refactor the code. It should be simpler and shorter yet remain readable. Does it make sense to make a class for this?

• tools for testing vim plugins

  - by intuited

  I'm looking for some tools for testing vim scripts. Either vim scripts that do unit/functional testing, or classes for some other library (eg Python's unittest module) that make it convenient to run vim with parameters that cause it to do some tests on its environment, and determine from the output whether or not a given test passed. I'm aware of a couple of vim scripts that do unit testing, but they're sort of vaguely documented and may or may not actually be useful: vim-unit: purports "To provide vim scripts with a simple unit testing framework and tools" first and only version (v0.1) was released in 2004 documentation doesn't mention whether or not it works reliably, other than to state that it is "fare [sic] from finished". unit-test.vim: This one also seems pretty experimental, and may not be particularly reliable. May have been abandoned or back-shelved: last commit was in 2009-11 ( 6 months ago) No tagged revisions have been created (ie no releases) So information from people who are using one of those two existent modules, and/or links to other, more clearly usable, options, are very welcome.

• SQl Server: serializable level not working

  I have the following SP: CREATE PROCEDURE [dbo].[sp_LockReader] AS BEGIN SET NOCOUNT ON; begin try set transaction isolation level serializable begin tran select * from teste commit tran end try begin catch rollback tran set transaction isolation level READ COMMITTED end catch set transaction isolation level READ COMMITTED END The table "test" has many values, so "select * from teste" takes several seconds. I run the sp_LockReader at same time in two diferent query windows and the second one starts showing test table contents without the first one terminates. Shouldn't serializeble level forces the second query to wait? How do i get the described behaviour? Thanks

• What ASP.NET MVC project files should I not add to Subversion

  - by Dan

  this is likely a naive question, but I want to do this right the first time. I have a MVC solution which has the following: Data project - C# Services project - C# MVC Web Project - ASP.NET MVC Test Project Currently, I am using the MVC2 source as a means to debug my own code. I do not plan on checking that in, but I realize once I go back to the MVC2 DLL, my solution will change. I'm pretty sure I just shouldn't check in stuff that changes with each build: the bin folder on the Web project, for example. Is there a list of what not to commit to source control? :)

• Distribute Windows (XP or 7) as virtual appliance

  - by User32

  I'm looking at ways that may be possible to distribute a Microsoft Windows (e.g. 7) virtual appliance (such as VMWare image) pre-configured and installed with a large application of mine. Is this possible? If not, is it perhaps best to ask clients to perform a virtual appliance installation on their site and then install my application via a script of some sort? For these kinds of scenarios I see that open source OSes are heavily used, but in my case I cannot use Linux or any other open source OS due to some requirements.

• unable to connect to remote sql server from SHDSL router

  - by user529265

  Got a new leased line network to our office that came with a SHDSL router (Watson). Currently, we are unable to use Sql Server management studio to connect to remote Sql databases. It errors out saying A connection was successfully established with the server, but then an error occurred during the pre-login handshake. (provider: TCP Provider, error: 0 - The specified network name is no longer available.) (Microsoft SQL Server, Error: 64) I logged into the Watson management panel and unblocked all the ports for TCP traffic (specified the range as 0 to 60000 and UDP as well - this include 1443 required for connecting to SQL Server). The router is the only thing that has changed. We are able to connect to it from other networks just fine. Is there something we are missing here. Any help would be greatly appreciated.

• Re-downloading Microsoft SQL Server 2008 Standard because of license issues?

  - by James Watt

  I have many clients who have purchased Microsoft SQL Server 2008 Standard. Unlike other Microsoft software, there is not a serial number provided for each customer to install the software. Futhermore, Microsoft's TechNet website lists this information about SQL Server instead of providing a key: "This product is pre-pidded." This means that the configuration file for SQL server contains your serial number instead of manually entering it. My question is then: does this serial change for each customer? The reason I ask: I'd rather not download a 3.2GB disc image over and over again for each of my customers individually. But, I don't want to risk using the same image over and over again resulting in Microsoft banning the serial for over use (as opposed to each customer using their copy with THEIR serial number.) Thanks in advance.
