• is there evidence that offshoring is causing developer salaries to go down? [closed]

  - by jcollum

  I realize this is a controversial and political topic. I'm trying to decide if offshoring is something that is effecting our industry in any substantial way or if it's just some bugaboo. I've read various posts on SO about it, but none addressed the idea of evidence for offshoring. Studies, papers, opinions of people who know about such things etc. I hear a lot about offshoring and its effect on our job market. However it all seems to be hearsay and conjecture. It does seem like some people are genuinely worried about it. This offshoring thing has been going on for quite some time, should be enough time for some real data to come out. If I had to pick a number I'd say it started during the dotcom boom -- a time when the need for developers far outweighed the local talent pool. We're now in a time when the talent pool is expensive and corporate wallets are tight, seems like an ideal time to find a good cheap developer in some other country. But is that actually happening? From reading some posts here on SO, I've concluded that offshoring is a really tough thing to do right. There are a lot of companies who think (or say) they can do it right, but some small percentage of them are actually able to pull it off. Is offshoring affecting the job market in any measurable way? Is offshoring measurable at all? Do we need to stop worrying about this?

• Intercepting hyperlinks in an embedded Word document

  - by Ryan

  Hello, I'm working on an app which uses embedded Word documents. We have a feature which allows them to insert a small clickable image into the doc - when the user clicks on it, we want the app to open another window based on some data specified by the user when the image was added. What the application does now is: When the image is inserted, the app creates a hyperlink for it and the data is used as the link destination The user ctrl+clicks on the image and the Word document the WindowSelectionChange event The app handles the WindowSelectionChange event and goes to open the specified window This approach worked fine with previous versions, when we had the 11.0 / Word 2003 interop dll's. We upgraded to 12.0/Word 2007 for the upcoming release, and in many cases the event is not firing when I click on the image - sometimes it does, sometimes it doesn't, and I'm descending into the cargo-cult world trying to figure out why - sometimes saving and re-opening the document works, sometimes killing the Word process and starting a new one fixes (or breaks) the feature. My guess is there's something going wrong with the WinSelChg event, but I'm not sure what. The usual process we have for applying the event handler is: try //remove the old one if any { ((Document)myAXFramerControl.ActiveDocument).Application.WindowSelectionChange -= new ApplicationEvents4_WindowSelectionChangeEventHandler(WSC_eventhandlerfunction); } catch{} ((Document)myAXFramerControl.ActiveDocument).Application.WindowSelectionChange += new ApplicationEvents4_WindowSelectionChangeEventHandler(WSC_eventhandlerfunction); Sometimes one or both of these will throw exceptions - usually a NullReferenceException when removing the handler. Adding the handler sometimes throws the "com object that has been separated from its underlying rcw cannot be used" exception, which I don't understand at all - my impression was that this only occurs when you, say, store a reference to the Word application or document and try to use it later. As it stands the WSC event handler is frequently never run; while I'm happy to fiddle with the app until it works once I can't really expect the same of the users who have been happily using this feature for a while now. Any ideas?

• oData/ADO.NET Data Services using LINQ-to-SQL with a decryption layer

  - by Program.X

  I have written an application using LINQ-to-SQL that submits a web form into a database. I absact the LINQ-to-SQL away using a Repository pattern. This repository has the basic methods: Get(), Save(), etc. As a development of the project, I needed to encrypt certain fields in the form. This was trivial, as I just added the encryption calls to the Get(), Save() methods in the Repository. Now, I want to put an oData layer over it, to allow RESTful extraction from MS Excel 2010 (when it comes out). I have this working, after a few stumbles on useless error messages, etc. However, obviously, those encrypted fields are still encrypted. My repository pattern would have decrypted these for me. As far as I know, I have to directly bind my oData service to the LINQ-to-SQL context for the schema, etc. to work - unless I enter a whole world of pain (any URLs appreciated). Is there a way I can insert my encryption/decryption layer into the request so decryption is done "on the fly"? I looked at the OnStartProcessingRequest() overload of DataService but this doesn't seem that useful.

• Did the Unity Team fix that "generics handling" bug back in 2008?

  - by rasx

  At my level of experience with Unity it might be faster to ask whether the "generics handling" bug acknowledged by ctavares back in 2008 was fixed in a public release. Here was the problem (which might be my problem today): Hi, I get an exception when using .... container.RegisterType(typeof(IDictionary<,), typeof(Dictionary<,)); The exception is... "Resolution of the dependency failed, type = \"IDictionary2\", name = \"\". Exception message is: The current build operation (build key Build Key[System.Collections.Generic.Dictionary2[System.String,System.String], null]) failed: The current build operation (build key Build Key[System.Collections.Generic.Dictionary2[System.String,System.String], null]) failed: The type Dictionary2 has multiple constructors of length 2. Unable to disambiguate. When I attempt... IDictionary myExampleDictionary = container.Resolve(); Here was the moderated response: There are no books that'll help, Unity is a little too new for publishers to have caught up yet. Unfortunately, you've run into a bug in our generics handling. This is currently fixed in our internal version, but it'll be a little while before we can get the bits out. In the meantime, as a workaround you could do something like this instead: public class WorkaroundDictionary : Dictionary { public WorkaroundDictionary() { } } container.RegisterType(typeof(IDictionary<,),typeof(WorkaroundDictionary<,)); The WorkaroundDictionary only has the default constructor so it'll inject no problem. Since the rest of your app is written in terms of IDictionary, when we get the fixed version done you can just replace the registration with the real Dictionary class, throw out the workaround, and everything will still just work. Sorry about the bug, it'll be fixed soon!

• Nginx for static files, Apache isn't working now...

  - by matthewsteiner

  So anything that is a "static file" that exists will just be done with nginx. Otherwise, it should pass it off to Apache. Right now, static files are working correctly. However, if something is passed to apache and it's example.com or subdomain.example.com, apache just spits out the "Apache 2 Test Page" that you get if there's nothing there. Here's my nginx.conf: location ~* ^.+.(jpg|jpeg|gif|png|ico|css|zip|tgz|gz|rar|bz2|doc|xls|exe|pdf|ppt|txt|tar|mid|midi|wav|bmp|rtf|js)$ { root /var/www/vhosts/example.com/public/; access_log off; expires 30d; } location / { proxy_pass http://127.0.0.1:8080/; proxy_redirect off; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; } Apache worked fine before, so I'm guessing it has to do with the way nginx is "asking". I'm not sure though. Any ideas?

• Adding a minimum display time for Silverlight splash screen.

  - by David

  When hosting a silverlight application on a webpage it is possible to use the splashscreensource parameter to specify a simple Silverlight 1.0 (xaml+javascript) control to be displayed while the real xap file is downloaded, and which can receive notification of the downloads progress through onSourceDownloadProgressChanged. If the xap file is in cache, the splash screen is not shown (and if the download only takes 1 second, the splash screen will only be shown for 1 second). I know this is not best practice in general, but I am looking for a way to specify a minimum display time for the splash screen - even if the xap cached or the download is fast, the splash screen would remain up for at least, let's say, 5 seconds (for example to show a required legal disclaimer, corporate identity mark or other bug). I do want to do it in the splash screen exclusively (rather then in the main xap) as I want it to be clean and uninterupted (for example a sound bug) and shown to the user as soon as they open the page, rather then after the download (which could take anywhere from 1 to 20+ seconds). I'd prefer not to accomplish this with preloading - replacing the splash screen with a full Silverlight xap application (with it's own loading screen), which then programmably loads and displays the full xap after a minimum wait time.

• Testing In-App-Billing with not published App

  - by Janusz

  I have an Android App that uses In-App-Billing to sell Account Managed Items. I tested the App with the static respons ids and everything seems to work. I now want to test the App with real product Ids. I created the App in the Google Play Store and uploaded a draft Version of the App with the correct Permissions. I know created an In-App-Billing item and published the item. At the moment the App is unpublished, the item is created and published and I have a test account that is registered in the Profile of the developer account and is the only account on the device that I use for testing. The App is signed with the same key as the uploaded draft. Edit:I'm testing with Android 4.1 && 4.03 at the moment If I try to buy the item the Google Play Store pops up but shows a dialog with the following method: The item you requested is not available for purchase. How can I test buying the item without publishing the App?

• Ignore LD_LIBRARY_PATH and stick with library given through -rpath at link time

  - by roe

  I'm sitting in an environment which I have no real control over (it's not just me, so basically, I can't change the environment or it won't work for anyone else), the only thing I can affect is how the binary is built. My problem is, the environment specifies an LD_LIBRARY_PATH containing a libstdc++ which is not compatible with the compiler being used. I tried compiling it statically, but that doesn't seem possible for g++ (version 4.2.3, seems to have been work done in this direction in later versions though which are not available, -static-libstdc++ or something like that). Now I've arrived at using rpath to bake the absolute path name into the executable (would work, all machines it's supposed to run on are identical). Unfortunately it appears as though LD_LIBRARY_PATH takes precedence over rpath (resetting LD_LIBRARY_PATH confirmed that it's able to find the library, but as stated above, LD_LIBRARY_PATH will be set for everyone, and I cannot change that). Is there any way I can make rpath take precedence over LD_LIBRARY_PATH, or are there any other possible solutions to my problem? Note that I'm talking about dynamic linking at runtime, I am able to control the command line at compile and link time. Thanks.

• Implementing Model-level caching

  - by Byron

  I was posting some comments in a related question about MVC caching and some questions about actual implementation came up. How does one implement a Model-level cache that works transparently without the developer needing to manually cache, yet still remains efficient? I would keep my caching responsibilities firmly within the model. It is none of the controller's or view's business where the model is getting data. All they care about is that when data is requested, data is provided - this is how the MVC paradigm is supposed to work. (Source: Post by Jarrod) The reason I am skeptical is because caching should usually not be done unless there is a real need, and shouldn't be done for things like search results. So somehow the Model itself has to know whether or not the SELECT statement being issued to it worthy of being cached. Wouldn't the Model have to be astronomically smart, and/or store statistics of what is being most often queried over a long period of time in order to accurately make a decision? And wouldn't the overhead of all this make the caching useless anyway? Also, how would you uniquely identify a query from another query (or more accurately, a resultset from another resultset)? What about if you're using prepared statements, with only the parameters changing according to user input? Another poster said this: I would suggest using the md5 hash of your query combined with a serialized version of your input arguments. This would require twice the number of serialization options. I was under the impression that serialization was quite expensive, and for large inputs this might be even worse than just re-querying. And is the minuscule chance of collision worth worrying about? Conceptually, caching in the Model seems like a good idea to me, but it seems in practicality the developer should have direct control over caching and write it into the controller. Thoughts/ideas? Edit: I'm using PHP and MySQL if that helps to narrow your focus.

• GCC/X86, Problems with relative jumps

  - by Ian Kelly

  I'm trying to do a relative jump in x86 assembly, however I can not get it to work. It seems that for some reason my jump keeps getting rewritten as an absolute jump or something. A simple example program for what I'm trying to do is this: .global main main: jmp 0x4 ret Since the jmp instruction is 4 bytes long and a relative jump is offset from the address of the jump + 1, this should be a fancy no-op. However, compiling and running this code will cause a segmentation fault. The real puzzler for me is that compiling it to the object level and then disassembling the object file shows that it looks like the assembler is correctly doing a relative jump, but after the file gets compiled the linker is changing it into another type of jump. For example if the above code was in a file called asmtest.s: $gcc -c asmtest.s $objdump -D asmtest.o ... Some info from objdump 00000000 <main>: 0: e9 00 00 00 00 jmp 5 <main+0x5> 5: c3 ret This looks like the assembler correctly made a relative jump, although it's suspicious that the jmp instruction is filled with 0s. I then used gcc to link it then disassembled it and got this: $gcc -o asmtest asmtest.o $objdump -d asmtest ...Extra info and other disassembled functions 08048394 <main>: 8048394: e9 6b 7c fb f7 jmp 4 <_init-0x8048274> 8048399: c3 ret This to me looks like the linker rewrote the jmp statement, or substituted the 5 in for another address. So my question comes down to, what am I doing wrong? Am I specifying the offset incorrectly? Am I misunderstanding how relative jumps work? Is gcc trying to make sure I don't do dangerous things in my code?

• How do I write a J2EE/EJB Singleton?

  - by Bears will eat you

  A day ago my application was one EAR, containing one WAR, one EJB JAR, and a couple of utility JAR files. I had a POJO singleton class in one of those utility files, it worked, and all was well with the world: EAR |--- WAR |--- EJB JAR |--- Util 1 JAR |--- Util 2 JAR |--- etc. Then I created a second WAR and found out (the hard way) that each WAR has its own ClassLoader, so each WAR sees a different singleton, and things break down from there. This is not so good. EAR |--- WAR 1 |--- WAR 2 |--- EJB JAR |--- Util 1 JAR |--- Util 2 JAR |--- etc. So, I'm looking for a way to create a Java singleton object that will work across WARs (across ClassLoaders?). The @Singleton EJB annotation seemed pretty promising until I found that JBoss 5.1 doesn't seem to support that annotation (which was added as part of EJB 3.1). Did I miss something - can I use @Singleton with JBoss 5.1? Upgrading to JBoss AS 6 is not an option right now. Alternately, I'd be just as happy to not have to use EJB to implement my singleton. What else can I do to solve this problem? Basically, I need a semi-application-wide* hook into a whole bunch of other objects, like various cached data, and app config info. As a last resort, I've already considered merging my two WARs into one, but that would be pretty hellish. *Meaning: available basically anywhere above a certain layer; for now, mostly in my WARs - the View and Controller (in a loose sense).

• A question on delegates and method parameters

  - by Srinivas Reddy Thatiparthy

  public class Program { delegate void Srini(string param); static void Main(string[] args) { Srini sr = new Srini(PrintHello1); sr += new Srini(PrintHello2); //case 2: sr += new Srini(delegate(string o) { Console.WriteLine(o); }); sr += new Srini(delegate(object o) { Console.WriteLine(o.ToString()); }); //case 4: sr += new Srini(delegate { Console.WriteLine(“This line is accepted,though the method signature is not Comp”); });//case 5 sr("Hello World"); Console.Read(); } static void PrintHello1(string param) { Console.WriteLine(param); } static void PrintHello2(object param) { Console.WriteLine(param); } } Compiler doesn't complain about the case 2(see the comment),well,the reason is straight forward since string inherits from object. ,along the same lines ,Why is it complaining for anonymous method types(see the comment //case 4:) that “Cannot convert anonymous method to delegate type 'DelegateTest.Program.Srini' because the parameter types do not match the delegate parameter types” where as in case of normal method it doesn't ?or am i comparing apples with oranges? Another case is why is it accepting anonymous method without parameters?

• Performance of Java matrix math libraries?

  - by dfrankow

  We are computing something whose runtime is bound by matrix operations. (Some details below if interested.) This experience prompted the following question: Do folk have experience with the performance of Java libraries for matrix math (e.g., multiply, inverse, etc.)? For example: JAMA: http://math.nist.gov/javanumerics/jama/ COLT: http://acs.lbl.gov/~hoschek/colt/ Apache commons math: http://commons.apache.org/math/ I searched and found nothing. Details of our speed comparison: We are using Intel FORTRAN (ifort (IFORT) 10.1 20070913). We have reimplemented it in Java (1.6) using Apache commons math 1.2 matrix ops, and it agrees to all of its digits of accuracy. (We have reasons for wanting it in Java.) (Java doubles, Fortran real*8). Fortran: 6 minutes, Java 33 minutes, same machine. jvisualm profiling shows much time spent in RealMatrixImpl.{getEntry,isValidCoordinate} (which appear to be gone in unreleased Apache commons math 2.0, but 2.0 is no faster). Fortran is using Atlas BLAS routines (dpotrf, etc.). Obviously this could depend on our code in each language, but we believe most of the time is in equivalent matrix operations. In several other computations that do not involve libraries, Java has not been much slower, and sometimes much faster.

• Does Java 6 open a default port for JMX remote connections?

  - by Bob Cross

  My specific question has to do with JMX as used in JDK 1.6: if I am running a Java process using JRE 1.6 with com.sun.management.jmxremote in the command line, does Java pick a default port for remote JMX connections? Backstory: I am currently trying to develop a procedure to give to a customer that will enable them to connect to one of our processes via JMX from a remote machine. The goal is to facillitate their remote debugging of a situation occurring on a real-time display console. Because of their service level agreement, they are strongly motivated to capture as much data as possible and, if the situation looks too complicated to fix quickly, to restart the display console and allow it to reconnect to the server-side. I am aware the I could run jconsole on JDK 1.6 processes and jvisualvm on post-JDK 1.6.7 processes given physical access to the console. However, because of the operational requirements and people problems involved, we are strongly motivated to grab the data that we need remotely and get them up and running again. EDIT: I am aware of the command line port property com.sun.management.jmxremote.port=portNum The question that I am trying to answer is, if you do not set that property at the command line, does Java pick another port for remote monitoring? If so, how could you determine what it might be?

• C#/LINQ: How to define generically a keySelector for a templated class before calling OrderBy

  - by PierrOz

  Hi Folks, I have the following class defined in C# class myClass<T,U> { public T PropertyOne { get; set; } public U PropertyTwo { get; set; } } I need to write a function that reorder a list of myClass objects and takes two other parameters which define how I do this reorder: does my reordering depend on PropertyOne or PropertyTwo and is it ascending or descending. Let's say this two parameters are boolean. With my current knowledge in LINQ, I would write: public IList<myClass<T,U>> ReOrder(IList<myClass<T,U>> myList, bool usePropertyOne, bool ascending) { if (usePropertyOne) { if (ascending) { return myList.OrderBy(o => o.PropertyOne).ToList(); } else { return myList.OrderByDescending(o => o.PropertyOne).ToList(); } } else { if (ascending) { return myList.OrderBy(o => o.PropertyTwo).ToList(); } else { return myList.OrderByDescending(o => o.PropertyTwo).ToList(); } } } What could be a more efficient/elegant way to do that ? How can I declare the Func,TResult keySelector object to reuse when I call either OrderBy or OrderByDescending? I'm interesting in the answer since in my real life, I can have more than two properties.

• CSS Design question, I've got myself completely turned around.

  - by Matt Dawdy

  Okay, I have a couple of other questions out there, but I think I'd better just ask from the beginning how you CSS experts would do this. Client's page is split into 2 rows -- header has some info, some aligned to left of page, some to right, some in the middle. This is currently done using a table. I'm fine with leaving this alone or changing it. My real question is that I need a page layout to handle the following: 2 columns - column on left is 200px, but can be "close" down to to 10px (not a slider, it's either 200 or 10 px). The column on the right needs to be as big as it needs to be -- which might be larger than the width of the page. When left column is "closed" then the right column slides over of course. Again, this right column might be 300px or it might be 4000 pixels (it's a reporting interface). Now, to add another wrinkle, SOME pages have 3 columns. The first 2 columns are each exactly 200px, and both can be "closed" down to 10 px each. But, the user may not close both columns, maybe just 1. Or none. Or both. The third column needs to act just like I described above, being able to be larger than the page width, and sliding over to take advantage of any of the "closed" left columns. Whew! I'm pretty confused as to how to go about this, as either I get it right but I can't scroll over to the right at all (overflow: hidden) and information is lost, or the right column jumps down below the left 2 columns and just looks plain stupid. My minimum browser requirements are IE8, FF3.5, Chrome and Safari (latest versions of all). Any and all pointers are gladly accepted.

• Help understanding .NET delegates, events, and eventhandlers

  - by Seth Spearman

  Hello, In the last couple of days I asked a couple of questions about delegates HERE and HERE. I confess...I don't really understand delegates. And I REALLY REALLY REALLY want to understand and master them. (I can define them--type safe function pointers--but since I have little experience with C type languages it is not really helpful.) Can anyone recommend some online resource(s) that will explain delegates in a way that presumes nothing? This is one of those moments where I suspect that VB actually handicaps me because it does some wiring for me behind the scenes. The ideal resource would just explain what delegates are, without reference to anything else like (events and eventhandlers), would show me how all everything is wired up, explain (as I just learned) that delegates are types and what makes them unique as a type (perhaps using a little ildasm magic)). That foundation would then expand to explain how delegates are related to events and eventhandlers which would need a pretty good explanation in there own right. Finally this resource could tie it all together using real examples and explain what wiring DOES happen automatically by the compiler, how to use them, etc. And, oh yeah, when you should and should not use delegates, in other words, downsides and alternatives to using delegates. What say ye? Can any of you point me to resource(s) that can help me begin my journey to mastery? EDIT One last thing. The ideal resource will explain how you can and cannot use delegates in an interface declaration. That is something that really tripped me up. Thanks for your help. Seth

• Space-saving character encoding for japanese?

  - by Constantin

  In my opinion a common problem: character encoding in combination with a bitmap-font. Most multi-language encodings have an huge space between different character types and even a lot of unused code points there. So if I want to use them I waste a lot of memory (not only for saving multi-byte text - i mean specially for spaces in my bitmap-font) - and VRAM is mostly really valuable... So the only reasonable thing seems to be: Using an custom mapping on my texture for i.e. UTF-8 characters (so that no space is waste). BUT: This effort seems to be same with use an own proprietary character encoding (so also own order of characters in my texture). In my specially case I got texture space for 4096 different characters and need characters to display latin languages as well as japanese (its a mess with utf-8 that only support generall cjk codepages). Had somebody ever a similiar problem (I really wonder, if not)? If theres already any approach? Edit: The same Problem is described here http://www.tonypottier.info/Unicode_And_Japanese_Kanji/ but it doesnt provide an real solution how to save these bitmapfont mappings to utf-8 space efficent. So any further help is welcome!

• Can iPad/iPhone Touch Points be Wrong Due to Calibration?

  - by Kristopher Johnson

  I have an iPad application that uses the whole screen (that is, UIStatusBarHidden is set true in the Info.plist file). The main window's frame is set to (0, 0, 768, 1024), as is the main view in that frame. The main view has multitouch enabled. The view has code to handle touches: - (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event { for (UITouch *touch in touches) { CGPoint location = [touch locationInView:nil]; NSLog(@"touchesMoved at location %@", NSStringFromCGPoint(location)); } } When I run the app in the simulator, it works pretty much as expected. As I move the mouse from one edge of the screen to the other, reported X values go from 0 to 767. Reported Y values go from 20 to 1023, but it is a known issue that the simulator doesn't report touches in the top 20 pixels of the screen, even when there is no status bar. Here's what's weird: When I run the app on an actual iPad, the X values go from 0 to 767 as expected, but reported Y values go from -6 to 1017. The fact that it seems to work properly on the simulator leads me to suspect that real devices' touchscreens are not perfectly calibrated, and mine is simply reporting values six pixels too low. Can anyone verify that this is the case? Otherwise, is there anything else that could account for the Y values being six pixels off from what I expect? (In a few days, I should have a second iPad, so I can test this with another device and compare the results.)

• Beginner's guide for rails

  - by piemesons

  Hello friends i need a book/ tutorials for rails without using scoffold. All the books mentioned in the other questions are creating some depot application or etc using scaffold and then explaining things. I believe in the thing that creating big depot is worthless when you are not getting anything. All of my frnds are suggesting me to go for this pragmatic book. look i understand the book is good but i m not getting the proper things. I got the logic cause i m good in php doctrine. asp.net c c++ so i m getting the things but i m not feeling confident. I want to have a another book. Can anybody suggest me some other books. I m saying this cause it really feels good when u create a simple form and insert the values in db and u can retreive those values and MOST IMP you can explain the whole logic of the that small form application instaed of that colorfull Depot application in which things are done with scaffold and u r not getting the thing and u are confused abt the real picture.

• Embedded Jetty resourceBase classpath URL

  - by drewzilla

  I'm embedding Jetty in a Spring based application. I configure my Jetty server in a Spring context file. The specific part of the configuration I'm having trouble with is this: <bean class="org.eclipse.jetty.webapp.WebAppContext"> <property name="contextPath" value="/" /> <property name="resourceBase" value="????????" /> <property name="parentLoaderPriority" value="true" /> </bean> If you see above, where I've put the ????????, I ideally want the resourceBase to reference a folder on my classpath. I'm deploying my application in a single executable JAR file and have a folder config/web/WEB-INF on my classpath. Jetty seems to be able to handle URLs defined in the resourceBase (e.g. jar:file:/myapp.jar!/config/web) but it doesn't seem to support classpath URLs. I get an IllegalArgumentException if I define something like classpath:config/web. This is a real pain for me. Does anyone know of anyway to achieve this functionality? Thanks, Andrew

• Best support now on windows: Mercurial or Git?

  - by mamcx

  I want to change my current subversion setup to Mercurial or Git. I read about the two and I have a conflicted view about how well they work on windows. Alot of pages say Git is sub-par on windows, slow and badly integrated. And almost everyone say Mercurial is better. But some say Git now is better and Mercurial is behind. I check the screenshots of TortoiseHG and TortoiseGIT and the mercurial one look "worse"... but maybe is just crappy screenshots? I read about the two, prefer the command-line interface of Mercurial, but seriously, I don't pretend to touch the command line. And if one of the two is a real improvenment to SVN, I don't have to do that (In SVN is necesary go to the metal because something need fix). In SVN I have issues when commit or get code made on OSX (I code on Windows, OSX, Solaris. Mainly windows). So I hope don't get that issues again (I mean, failure to commit to the repo). I have a small repository, doing solo.
