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

  - by Dimitri C.

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

• Within a DLL, how is the function table structured?

  - by Willi Ballenthin

  I've been looking into the implementation of a device library that doesn't explicitly support my operating system. In particular, I have a disassembled DLL, and a fair amount of supporting source code. Now, how is the function table/export table structured? My understanding is that the first structure of the .data section is a table of VRAs. Next is a table of strings linked by index to that first address table. This makes sense to me, as a linker could translate between symbols and addresses. How do functions referenced by ordinals fit into this picture? How does one know which function has such and such ordinal number, and how does the linker resolve this? In other words, given that some other DLL imports SOME_LIBRARY_ordinal_7, how does the linker know which function to work with? Thanks, all! edit More information... Im working with the FTDI libraries, and would like to resolve which function is being invoked. In particular, I see something like: extern FTD2XX_Ordinal_28: near how might I go about determining which function is being referenced, and how does the linker do this?

• How good idea is it to use code contracts in Visual Studio 2010 Professional (ie. no static checking

  - by Lasse V. Karlsen

  I create class libraries, some which are used by others around the world, and now that I'm starting to use Visual Studio 2010 I'm wondering how good idea it is for me to switch to using code contracts, instead of regular old-style if-statements. ie. instead of this: if (String.IsNullOrWhiteSpace(fileName)) throw new ArgumentNullException("fileName"); (yes, I know, if it is whitespace, it isn't strictly null) use this: Contract.Requires(!String.IsNullOrWhiteSpace(fileName)); The reason I'm asking is that I know that the static checker is not available to me, so I'm a bit nervous about some assumptions that I make, that the compiler cannot verify. This might lead to the class library not compiling for someone that downloads it, when they have the static checker. This, coupled with the fact that I cannot even reproduce the problem, would make it tiresome to fix, and I would gather that it doesn't speak volumes to the quality of my class library if it seemingly doesn't even compile out of the box. So I have a few questions: Is the static checker on by default if you have access to it? Or is there a setting I need to switch on in the class library (and since I don't have the static checker, I won't) Are my fears unwarranted? Is the above scenario a real problem? Any advice would be welcome.

• [PHP] Local/Dev/Live deployment - best workflow

  - by Adam Kiss

  Hello, situation We our little company with 3 people, each has a localhost webserver and most projects (previous and current) are on one PC network shared disk. We have virtual server, where some of our clients' sites and our site. Our standard workflow is: Coder PC ? Programmer localhost ? dev domain (client.company.com) ? live version (client.com) It often happens, that there are two or three guys working on same projects at the same time - one is on dev version, two are on localhost. When finished, we try to synchronize the files on dev version and ideally not to mess up any files, which *knock knock * doesn't happen often. And then one of us deploys dev version on live webserver. question we are looking for a way to simplify this workflow while updating websites - ideally some sort of diff uploader or VCS probably (Git/SVN/VCS/...), but we are not completely sure where to begin or what way would be ideal, therefore I ask you, fellow stackoverflowers for your experience with website / application deployment and recommended workflow. We probably will also need to use Mac in process, so if it won't be a problem, that would be even better. Thank you

• Solutions to cubefarm lighting

  - by Khorkrak

  So with our recent move to the cubefarm out from our developer friendly shared office, we've altered the environment to reproduce our more programming conducive workspace as much as possible. Fortunately, we we're planted into the same aisle as QA. They're quiet and it's made it easier to pair up to review a problem. They've already unscrewed some of the fluorescent bulbs. We unscrewed the rest. Now the facilities coordinator and HR are wondering what to do. They want the office to have an open, bright and elegant feel to it as does the founder - think IKEA. Fortunately he's usually in the NYC office and rarely stops up where we work. There's some natural light from nearby windows and translucent office walls that ring the farm. So the facility coordinator doesn't understand - do you guys want incandescents overhead or... no we just don't want overhead lights. How to solve this while avoiding having a weird looking office space with a dark spot in the middle. Are there any better solutions - no we can't have an office as that's considered a management only perk.

• Job queueing and execute Mechanism

  - by Calm Storm

  In my webservice all method calls submits jobs to a queue. Basically these operations take long time to execute, so all these operations submit a Job to a queue and return a status saying "Submitted". Then the client keeps polling using another service method to check for the status of the job. Presently, what I do is create my own Queue, Job classes that are Serializable and persist these jobs (i.e, their serialized byte stream format) into the database. So an UpdateLogistics operation just queues up a "UpdateLogisticsJob" to the queue and returns. I have written my own JobExecutor which wakes up every N seconds, scans the database table for any existing jobs, and executes them. Note the jobs have to persisted because these jobs have to survive app-server crashes. This was done a long time ago, and I used bespoke classes for my Queues, Jobs, Executors etc. But now, I would like to know has someone done something similar before? In particular, Are there frameworks available for this ? Something in Spring/Apache etc Any framework that is easy to adapt/debug and plays well along with libraries like Spring will be great.

• Parallel doseq for Clojure

  - by andrew cooke

  I haven't used multithreading in Clojure at all so am unsure where to start. I have a doseq whose body can run in parallel. What I'd like is for there always to be 3 threads running (leaving 1 core free) that evaluate the body in parallel until the range is exhausted. There's no shared state, nothing complicated - the equivalent of Python's multiprocessing would be just fine. So something like: (dopar 3 [i (range 100)] ; repeated 100 times in 3 parallel threads... ...) Where should I start looking? Is there a command for this? A standard package? A good reference? So far I have found pmap, and could use that (how do I restrict to 3 at a time? looks like it uses 32 at a time - no, source says 2 + number of processors), but it seems like this is a basic primitive that should already exist somewhere. clarification: I really would like to control the number of threads. I have processes that are long-running and use a fair amount of memory, so creating a large number and hoping things work out OK isn't a good approach (example which uses a significant chunk available mem). update: Starting to write a macro that does this, and I need a semaphore (or a mutex, or an atom i can wait on). Do semaphores exist in Clojure? Or should I use a ThreadPoolExecutor? It seems odd to have to pull so much in from Java - I thought parallel programming in Clojure was supposed to be easy... Maybe I am thinking about this completely the wrong way? Hmmm. Agents?

• What is the best way of doing this? (WCF 4)

  - by Jason Porter

  I have a multith-threaded, continusly running application that connects with multiple devices via TCP/IP sockets and exposes a set of WCF API's for controlling, monitoring and reporting on these devices. I would like to host this on IIS for the ususal reasons of not having to worry about re-starting the app in case of errors. So the issue I have is the main application running in parallel with the WCF Servies. To accomplish this I use the static AppInitialize class to start a thread which has the main applicaiton loop. The WCF services mostly report or control the shared objects with this thread. There are two problems that I see with this approach. One is that if the thread dies, IIS has no clue to re-start it so I have to play some tricks with some WCF calls. The other is that the backrgound thread deals with potentially thousands of devices that are connected permanently (typically a thread per socket connection). So I am not sure if IIS is buying me anything in this case. Another approach that I am thinking is to use WF for the main application that deals with the sockets and host both the WF and my WCF services in IIS using AppFabric. Since I have not use WF or AppFabric I am reaching out to see if this would be good approach or there are better alternative.

• What is PocoCapsule current status?

  - by seas

  What is PocoCapsule current status? Is it evolving? Has it been forked with some other product? What is about the whole idea of IoC for C++? If PocoCapsule is not evolving, is it because IoC was considered not useful for C++, unsafe, other patterns appeared or something else? As far as I understand there are 2-3, maybe few more products, that implement IoC for C++, available and PocoCapsule is the most mature of them. I see several disadvantages in current version (as I see it's 1.1 from google code): No separate namespace. Header files are required to be right in INCLUDE folder - better to place them in subfolder. Generation Tools depend on Java. No static linking libraries are built by default. Cannot generate source code out of setup.xml for compilation and link with my app if I don't need reconfiguration feature. Does anybody have the same thoughts? Does anybody work on something of this list? Are there any barriers to start working, like patents?

• Phonegap: Will my mobile app 'feel' faster or slower once ported to phonegap?

  - by user15872

  So I'm designing everything in mobile Safari and I know that phonegap is essentially a stripped webview but... Question: Will my application will run better in phonegap? (revised below) a)I imagine my navigation and core app will load faster as the scripts and images are on the hard drive. Is this True? b)I assume since they've been working on it for 2 years now that they may have made some optimizations to make it quicker than just an average safari window. Is this true? (Assuming both html5/js/css code bases are pretty much the same and app is running on iOS.) Update: Sorry, I meant to compare apples to slightly different apples. Question 1 revised: Will my app see any performance benefits running with in a phonegap environment vs standard mobile safari? (compare mobile - to mobile) 1b) In what ways, other than loading time has phonegap optimized performance over standard mobile safari? Follow ups: 1) Are there any pitfalls, other than large libraries, that may cause phonegap to suffer a serious performance hit vs stand mobile safari? 2) Can I mix native and webview rendering? (i.e the top half of my app is rendered in with html/css/js and the bottom half native)

• Can I get away with this or is it just too crude and unpractical ?

  - by The_AlienCoder

  I spent the whole of last night searching for a free AspNet web chat control that I could simply drag into my website. Well the search was in vain as I could not find a control that matched my needs i.e List of users, 1 to 1 chat, Ability to kick out users.. In the end I decided to create my own control from scractch. Although it works well on my machine Im concerned that It maybe a little crude and unpractical on a shared hosting enviroment. Basically this is what I did : Created an sql database that stores the chat messages. Wrote the stored procedures and and included a statement that clears old messages Then the 'crude' part : Dragged an update panel and timer control on my page Dragged a Repeater databound to the chat messages table inside the update panel Dragged another update panel and inside it put a textbox and a button Configured the timer control to tick every 5 seconds. ..and then I made it all work like this In the timer tick event I 'refreshed' the messages display by invoking Databind() on my repeater i.e protected void Timer1_Tick(object sender, EventArgs e) { MyRepeater.DataBind(); } Then in my send button click event protected void btnSend_Click(object sender, EventArgs e) { MyDataLayer.InsertMessage(Message, Sender, CurrTime); } Well It works well on my machine and Ive got the other functionalities(users list, kick out user..) to work by simply creating more tables. But like I said it seems a little crude to me. so I need a proffesional opinion. Should I run with this or try another Approach ?

• How to secure connection strings in VS?

  - by salvationishere

  I see several others have posted this question, however, none of the solutions I've tried have fixed this yet. I have a 32-bit XP running VS 2008 and I am trying to encrypt my connection string in my web.config file. But I am getting the error: The configuration section '...' was not found. Failed! The command I give it: C:\Program Files\Microsoft Visual Studio 9.0\VCAspnet_regiis.exe -pe "system.we b/AdventureWorksConnectionString2" -app "/Documents and Settings/Admin/My Docume nts/Visual Studio 2008/Projects/AddFileToSQL2" Also, how does -app map virtual directory? In other words the path above is the directory right below c:. Is this the correct path to use? And AddFileToSQL2 is the name of my project, although it is part of the AddFileToSQL solution. I have this folder web shared with all of the permissions. And the relevant part of my web.config file: <add name="AdventureWorksConnectionString2" connectionString="Data Source=SIDEKICK;Initial Catalog=AdventureWorks;Persist Security Info=true; User ID=AdventureWorks;Password=sqlMagic" providerName="System.Data.SqlClient" />

• C++ RPC library suggestions

  - by Oxsnarder

  I'm looking for suggestions regarding RPC libraries implemented in C++, for C++ developers. Some requirements constraints: Should work on both linux/unix and win32 systems Be able to execute free function and class methods Hopefully written in modern C++ not 90's/java-esque C++ Be able to function over networks and hetrogenous architectures Not too slow or inefficient Hopefully provide interfaces for TR1 style std::function's et al. My example usage is to invoke the free function foo on a remote machine. ---snip--- // foo translation unit int foo(int i, int j) { return i + j; } ---snip--- ---snip--- // client side main int main() { //register foo on client and server //setup necassary connections and states int result; if (RPCmechanism.invoke("foo",4,9,result)) std::cout << "foo(4,9) = " result << std::endl; else std::cout << "failed to invoke foo(4,9)!" << std::endl; return 0; } ---snip--- Something that can achieve the above or similar would be great.

• Lucene raise document score if sibling entity matches query

  - by Pitagoras

  I have the following design situation. I use hibernate search (lucene in the back). Tha application manages ITEMs which have title, description and tags. These are full text indexed. On the other hand, we have COLLECTION of ITEMs. The user can create a COLLECTION and add as many ITEMs as she wants. ITEMs can also belong to many COLLECTIONs. I have a boosted query so that search terms that appear in the tags are more important than in the title, and lastly in the description. But I need an additional matching criteria: for a given ITEM, it whould rank better if other documents in some COLLECTION where the ITEM belongs, also match the query. This is like to say: the title/tags/description of "fellow" items (i.e. items in some shared collection) make the item rank better. I was thinking that adding an ITEM to a COLLECTION would add something like "extra tags" to every other ITEM in the collection, being these extra tags the elements to match in the added ITEM. I feel a more clever solution lucene-wise should exists. Any ideas/pointers are welcome. Thanks.

• Forms blank when rendering a partial when using a collection of objects. Help!

  - by dustmoo

  Alright, I know my title is a little obscure but it best describes the problem I am having. Essentially, I have a list of users, and want to be able to edit their information in-line using AJAX. Since the users are showing up in rows, I am using a partial to render the data and the forms (which will be hidden initially by the ajax), however, when the rows are rendered currently only the last item has it's form's fields populated. I suspect this has something to do with the fact that all the form fields have the same id's and it is confusing the DOM. But I don't know how to make sure the id's are unique. Here is a small example: In my view: <%= render :partial => 'shared/user', :collection => @users %> My partial (broke down to just the form) note that I am using the local variable "user" <% form_for user, :html => {:multipart => true} do |f| -%> <%= f.label :name, "Name*" %> <%= f.text_field :title, :class => "input" %> <%= f.label :Address, "Address" %> <%= f.text_field :address, :class => "input" %> <%= f.label :description, "Description*" %> <%= f.text_area :description, :class => "input" %> <% end -%> When the html is rendered each form has a unique id (for the id of the user) but the elements themselves all have the same id, and only the last user form is actually getting populated with values. Does anyone have any ideas?? :) Thanks in advance!

• TFS merging for users that are used to VSS

  - by JacksonD

  I just migrated a team of 7 developers from VSS to TFS. I migrated all of their code into a DEV folder which I then branched into a QA folder (which I branched into a PROD folder). The developers usually don't work on the same files, but there are some shared utility classes. All of the code is for a large ASP.NET web site. When the developers are ready to merge from DEV to QA, they only want to merge their changes. For example, let's say that Developer1 has been working on a project for the last 3 months and he's ready to merge all of his code into QA. However, Developer2 has been working on a different project for the last 2 months which is not ready to be merged. Developer1 and Developer2's changes are not in any way dependent on each other, but they are not separated into different folder structures and they each regularly do a get latest. There doesn't seem to be a way for developer1 to only merge his changes without also merging all of developer2's changes. Currently, developer1 is going through the Pending Changes window and 'Undoing Pending Changes' for all of Developer2's changes, but this is time consuming. They could merge each file individually, but this is also time consuming. Is there an easier way? I am going to have a coronary if I hear one more person explain how much easier it was to work in VSS.

• jQuery logic firing twice from a Usercontrol when used in a jQueryUI modal dialog

  - by AaronS

  I have an asp.net usercontrol that I'm using to put a bunch of HTML and Jquery logic into to be shared on several pages. This usercontrol has some dropdown boxes loaded from json calls and has no added codebehind logic. When I use this usercontrol on a normal page it works perfectly fine, and no issues at all. However, when I wrap the usercontrol in a div, and use a jqueryUI modal dialog, everything in the usercontrol fires twice. Not only code in the initial $(document).ready(function() {});, but also every function is also fired twice when called. Debugging this in Visual Studio, I see that everything is first being called from the external JS file, and then again from a "script block" file that is somehow getting generated on the fly. This script block file isn't getting generated on a page that doesn't wrap the user control in a modal. The same happens if I use IISExpress or IIS7. The question is, why is this script block file getting created, and why is all my jQuery logic firing twice? --edit-- Here is the div: <div id="divMyDiv" title="MyDiv"> <uc1:MyUserControl runat="server" ID="MyUsercontrol" /> </div> Here is the modal logic that uses it: $("#divMyDiv").dialog({ autoOpen: false, height: 400, width: 400, modal: true, open: function (type, data) { $(this).parent().appendTo("form"); } }); Note: The problm still occurs, even if I remove the "open:" function. But, it does not occur if I remove the entire dialog block, so it is specific to this dialog call.

• Easier way to populate form data and validation data in Code Igniter?

  - by John

  I'm new to code igniter. I'm following the form validation tutorial found at: http://www.codeignitor.com/user_guide/libraries/validation.html I find I am typing too much in the view to get the form to re-populate. For example, here's what one of my INPUT fields look like: <input type="text" name="email" value="<?=$this->validation->email ? $this->validation->email : $array_db_values['email'] ?>" /> Basically, when the form first loads, it should show a value from the database. If the user alters the value and it fails validation, then the form should post the erroneously submitted value. Does code igniter have a "cleaner" way of rendering this kind of output? Otherwise, I'm going to do something like this in my controller: $array_db_values = getdbresults(); if($_POST['submit']) foreach($_POST as $key=>$val) $array_db_values[$key] = $val; That way, if postback data exists, it will always override database values. Then input fields in my view can simply be: <input type="text" name="email" value="<?=$array_db_values['email'] ?>" /> Is there a better/native CI way to handle this scenario?

• Using a Data Management Singleton

  - by Dan Ray

  Here's my singleton code (pretty much boilerplate): @interface DataManager : NSObject { NSMutableArray *eventList; } @property (nonatomic, retain) NSMutableArray *eventList; +(DataManager*)sharedDataManager; @end And then the .m: #import "DataManager.h" static DataManager *singletonDataManager = nil; @implementation DataManager @synthesize eventList; +(DataManager*)sharedDataManager { @synchronized(self) { if (!singletonDataManager) { singletonDataManager = [[DataManager alloc] init]; } } NSLog(@"Pulling a copy of shared manager."); return singletonDataManager; } So then in my AppDelegate, I load some stuff before launching my first view: NSMutableArray *eventList = [DataManager sharedDataManager].eventList; .... NSLog(@"Adding event %@ to eventList", event.title); [eventList addObject:event]; NSLog(@"eventList now has %d members", [eventList count]); [event release]; As you can see, I've peppered the code with NSLog love notes to myself. The output to the Log reads like: 2010-05-10 09:08:53.355 MyApp[2037:207] Adding event Woofstock Music Festival to eventList 2010-05-10 09:08:53.355 MyApp[2037:207] eventList now has 0 members 2010-05-10 09:08:53.411 MyApp[2037:207] Adding event Test Event for Staging to eventList 2010-05-10 09:08:53.411 MyApp[2037:207] eventList now has 0 members 2010-05-10 09:08:53.467 MyApp[2037:207] Adding event Montgomery Event to eventList 2010-05-10 09:08:53.467 MyApp[2037:207] eventList now has 0 members 2010-05-10 09:08:53.524 MyApp[2037:207] Adding event Alamance County Event For June to eventList 2010-05-10 09:08:53.524 MyApp[2037:207] eventList now has 0 members ... What gives? I have no errors getting to my eventList NSMutableArray. But I addObject: fails silently?

• How to parse mathematical expressions involving parentheses

  - by Rob P.

  Please forgive my title, I really don't know how to phrase it better. This isn't a school assignment or anything, but I realize it's a mostly academic question. But, what I've been struggling to do is parse 'math' text and come up with an answer. For Example - I can figure out how to parse '5 + 5' or '3 * 5' - but I fail when I try to correctly chain operations together. (5 + 5) * 3 It's mostly just bugging me that I can't figure it out. If anyone can point me in a direction, I'd really appreciate it. EDIT Thanks for all of the quick responses. I'm sorry I didn't do a better job of explaining. First - I'm not using regular expressions. I also know there are already libraries available that will take, as a string, a mathematical expression and return the correct value. So, I'm mostly looking at this because, sadly, I don't "get it". Second - What I've tried doing (is probably misguided) but I was counting '(' and ')' and evaluating the deepest items first. In simple examples, this worked; but my code is not pretty and more complicated stuff crashes. When I 'calculated' the lowest level, I was modifying the string. So... (5 + 5) * 3 Would turn into 10 * 3 Which would then evaluate to 30 But it just felt 'wrong'. I hope that helps clarify things. I'll certainly check out the links provided.

• Should I learn two (or more) programming languages in parallel?

  - by c_maker

  I found entries on this site about learning a new programming language, however, I have not come across anything that talks about the advantages and disadvantages of learning two languages at the same time. Let's say my goal is to learn two new languages in a year. I understand that the definition of learning a new language is different for everyone and you can probably never know everything about a language. I believe in most cases the following things are enough to include the language in your resume and say that you are proficient in it (list is not in any particular order): Know its syntax so you can write a simple program in it Compare its underlying concepts with concepts of other languages Know best practices Know what libraries are available Know in what situations to use it Understand the flow of a more complex program At least know most of what you do not know I would probably look for a good book and pick an open source project for both of these languages to start with. My questions: Is it best to spend 5 months learning language#1 then 5 months learning language#2, or should you mix the two. Mixing them I mean you work on them in parallel. Should you pick two languages that are similar or different? Are there any advantages/disadvantages of let's say learning Lisp in tandem with Ruby? Is it a good idea to pick two languages with similar syntax or would it be too confusing? Please tell me what your experiences are regarding this. Does it make a difference if you are a beginner or a senior programmer?

• how to Add-in load again n again for every instance of an application?

  I have one qus. i created one shared add-in in c#.net. This add-in is working fine. now i want this add-in is load again n again when any office application is opened. For e.g. when i open any MS word document then add-in is load for that and if after that i opened another MS word document without closing previously opened document then add-in is again load for newly opend MS word document. But when i opened MS word at first time the add-in is load and if i opened MS word again but add-in is already loaded. my requirement is like that-my add-in is worked backgroundly that is its work only to record the opening,closing time of the word document and how much time spend onto that word document and also the name of this document. But when i opened one word document then add-in is loaded for that and if againg opened new word document then becaz of previously opened document add-in is not load for that document remember that priviously opened document is not closed. but if i closed previously opened document then for new document add-in is load.

• AIX 6.1 unable to build apache module

  - by user3715581

  In Aix 6.1/ Apache version 2.2.8 packaged as part of IBM WebSphere. We should have had mod_dumpio for this version but for some reasons IBM did not include it. So we are trying to build this module(in few many ways) but none of them worked. 1) Using apxs:- Failed with the "xlc_r" not found as compile option for libtool. So based on an article online, we changed to "gcc" and we have to remove -qmaxmem and -qHALT to make it work. Result we see a .lo created but LoadModule fails(unable to find .loader section). 2) Using gcc:- Command "gcc -fpic -DSHARED_MODULE -I -c mod_dumpio.c" After running this command, we can see .o file created and then we tried to execute "ld -Bshareable -o mod_dumpio.so mod_dumpio.o" whereas AIX complaining about -Bshareable so we tried using this command "gcc -shared -I -o mod_dumpio.so mod_dumpio.o" whereas the error was "libgcc_s" not found. Then we added -static-libgcc to the above command and it was not resolving .h file functions (Unknown symbols). From IBM AIX site, libgcc_s costs around $2k. We think our second approach may work but we dont know how to instruct gcc to look for .h files while building .so from .o. Any help is appreciated.

• Sharing code between two or more rails apps... alternatives to git submodules?

  - by jtgameover

  We have two separate rails_app, foo/ and bar/ (separate for good reason). They both depend on some models, etc. in a common/ folder, currently parallel to foo and bar. Our current svn setup uses svn:externals to share common/. This weekend we wanted to try out git. After much research, it appears that the "kosher" way to solve this is using git submodule. We got that working after separating foo,bar,common into separate repositories, but then realized all the strings attached: Always commit the submodule before committing the parent. Always push the submodule before pushing the parent. Make sure that the submodule's HEAD points to a branch before committing to it. (If you're a bash user, I recommend using git-completion to put the current branch name in your prompt.) Always run 'git submodule update' after switching branches or pulling changes. All these gotchas complicate things further than add,commit,push. We're looking for simpler ways to share common in git. This guy seems to have success using the git subtree extension, but that deviates from standard gitand still doesn't look that simple. Is this the best we can do given our project structure? I don't know enough about rails plugins/engines, but that seems like a possible RoR-ish way to share libraries. Thanks in advance.
