• Where to store selected language on multilingual site: session/cookies or url?

  - by tig

  I have a site that has all its content translated to multiple languages and has no accounts (to set prefered language there). I can detect preferred language using Accept-Language, ip or anything else. I have 3 ways to store user language selection: Detect language and store it in cookie/session and allow switching language (and also store it in cookie/session) Use detected language if there is no language specified in url, and show links to url with different language Use default site language and show links to other languages Storing langage in url can be of any type: different domain, subdomain, or somewhere in url I think about first case as it allows me to send one url to anyone and it will be presented to them in their preferred language. But another opinion is that different language means different data, so it must have different link.

• Enabling depth testing when using CAOpenGLLayer

  - by Andrew

  If one is using a subclass of NSOpenGLView then one enables depth testing by selecting a 16/24/32 bit buffer from the attributes menu in Xcode, and then adding glEnable(GL_DEPTH_TEST); glClear(GL_DEPTH_BUFFER_BIT); to the drawRect method. However, in the application I'm creating I'm rendering OpenGL content via the drawInCGLContext method of a CAOpenGLLayer which is contained within a subclass of NSView. This means that it is no longer possible to create a depth buffer via the inspector. Does anyone know how I can achieve this in such a situation?

• jQuery compatible JavaScript documentation generator

  - by clyfe

  I need to choose a documentation generator (similar to jdoc in java or rdoc in ruby) for my javascript project that (built with jquery, underscore and backbone) Candidates: jsdoc toolkit pdoc natural docs docco YUI doc doctool http://jquery.bassistance.de/docTool/docTool.html other ? Requirements should work with jquery, underscore and backbone. that means object-literal methods etc I really like pdoc but its too centered around prototype, poorly documented, and I don't want to make extra files (sections?) to make it work (not sure about this) docco is nice but I want structured output (as in menu + class/func structure like jdoc) must be command line/makefile compatible (not web pastie) Tips, tricks, tutorials, success stories, advice greatly welcomed. Why Doesn't jQuery use JSDoc?

• How do you write a consistent UI Automation for MS? MSAA & UI Automation don't seem to overlap.

  - by Greg

  Working on a general Automation tool, considering moving from Win32 Message hooks to .net UI Automation, however the feature set of UI Automation doesn't cover all we have in Win32 and still doesn't seem to support all the GUI on Windows. One such example is Windows Live Messenger. Windows Live messenger 2009 is still using the older DirectUIHwnd to draw the gui. This means that you can't use windows messages to send to the controls, because the controls don't have their own HWND. It also seems to defeat the new .net UI Automation framework though the documentation seems to make out as if it can be joined in the UI Automation and Microsoft Active Accessibility document. Looking at MS Accessibility pointed to Active Accessibility 2.0 SDK Tools which showed that MSAA can interact with the contents. Is there some trick to getting the older MSAA technology that UI Automation seems to be trying to replace to actually work with UI Automation? I'd rather not have multiple solutions trying to automate the same windows for windows unlike Windows Live Messenger where each of these techniques is valid and will work.

• iphone scanning a dat file for data

  - by Brodie4598

  I am trying to remake a program I have made in C# in OBJ-C.In C# I used streamreader to search the data file for the line I am looking for then convert that line into a string that I can work with. I have looked at NSScanner but I'm not sure if thats quite waht I'm looking for but I'm by no means a cocoa expert. All I would like to be able to do is have it search a data file for an occurance of a string, then when/if it finds an occurance of that string, it returns the line that string was found on as a string. Any ideas?

• Keyboard event issue

  - by Petar Minchev

  Hello guys! I have to capture the following keyboard event in a TextBox - SHIFT + 8(on the numpad). This also means the NumLock will be on. When I try the following, nothing is printed: private void textBox1_KeyDown(object sender, KeyEventArgs e) { if (e.Shift && e.KeyCode == Keys.NumPad8) Console.WriteLine("SHIFT + UP"); } But CTRL + 8(on the numpad) is working. private void textBox1_KeyDown(object sender, KeyEventArgs e) { if (e.Control && e.KeyCode == Keys.NumPad8) Console.WriteLine("CTRL + UP"); } Could someone explain me, why SHIFT + 8 isn't fired, but CTRL + 8 is working? P.S. I wrote + UP, because the user wants to navigate with the numpad arrows and the SHIFT key, but his NumLock will also be on. That's why I catch Keys.NumPad8. All the best, Petar

• How to use libraries compiled with MingW in MSVC?

  - by NumberFour

  Hello, I have compiled several libraries with MingW/MSYS... the generated static libraries are always .a files. When I try to link the library with a MSVC project, Visual Studio throws 'unresolved external symbols' ... It means that the .a static library is incompatible with MS C++ Linker. I presume it has to be converted to a MSVC compatible .lib file. Either .a and .lib are just AR archives of .o or .obj files, so is there any way how to use MingW compiled libs in a MSVC project? Or do I have to compile/link everything just in one compiler/linker - MSVC only/MingW only? The MingW compiler is said to be compatible with MSVC. I read a few threads about this topic, but they mostly say that renaming the file to .lib should do the work, but it unfortunately doesn't work for me. Thanks for any advice.

• Java preferences API throughput

  - by Domchi

  I'm using Java Preferences API to store window position and size of Swing application. At this moment, I'm listening to window resize/reposition events and storing the position and size every time they change. However, that means that if user slowly resizes window which is 200px wide to 400px wide, I'll probably write new window size about 200 times during pretty short time. Preferences API uses whichever datastore is available on the host system (windows registry for Windows etc.) - but the question is, what are limitations or best practices for properties API? Is it OK, or would it be smart to write only when user has finished resizing? Anyone had experiences with Properties API on different platforms?

• Defining - and dealing with - Evil

  - by Chris Becke

  As a software developer one sometimes gets feature requests that seem to be in some kind of morally grey area. Sometimes one can deflect them, or implement them in a way that feels less 'evil' - sometimes - on reflection - while the feature request 'feels' wrong theres no identifiable part of it that actually causes harm. Sometimes one feels a feature is totally innocent but various anti virus products start tagging one as malware. For example - I personally consider EULAs to (a) hopefully be unenforceable and (b) a means by which rights are REMOVED from consumers. However Anti Virus scanners frequently mark as malware any kind of download agent that does not display a EULA. Which to me is the result of a curious kind of double think. What I want to know is - are there any online (or offline) resources that cover evil software development practices? How can I know if a software practice that I consider dodgy is in fact evil enough to consider fighting?

• Java interface and abstract class issue

  - by George2

  Hello everyone, I am reading the book -- Hadoop: The Definitive Guide, http://www.amazon.com/Hadoop-Definitive-Guide-Tom-White/dp/0596521979/ref=sr_1_1?ie=UTF8&s=books&qid=1273932107&sr=8-1 In chapter 2 (Page 25), it is mentioned "The new API favors abstract class over interfaces, since these are easier to evolve. For example, you can add a method (with a default implementation) to an abstract class without breaking old implementations of the class". What does it mean (especially what means "breaking old implementations of the class")? Appreciate if anyone could show me a sample why from this perspective abstract class is better than interface? thanks in advance, George

• Placement of service methods

  - by mhp

  Let's assume I have two service classes with the following methods: GroupService createGroup() deleteGroup() updateGroup() findGroup() UserService createUser() deleteUser() updateUser() findUser() Now, I am thinking about the aesthetics of theses classes. Imagine we want to implement a method which search for all user of a specific group. Which service class is responsible for such a method? I mean, the return value is a user (or maybe a collection of users) but the parameter (which means the name of the group) is a group. So which service class is the better place to put this method in?

• How do I best run a search on Date when it is not a :has_many association?

  - by Angela

  I have a number of activities that have a calculated scheduled date. The activities, for example, Email, have a email.days method which is the days from a Contact.start_date on which it should be sent. This means contact.start_date + email.days yields a date on which email is sent to contact. I would like to use link_to around the date, so I can see all the emails and associated contacts that are to be scheduled on that date. However, this "date" is not an attribute or an associate, so I'm not linking to a model's view. It's calculated. So: 1) What should the actual "format" of the date that gets passed in the URl be? What is the method to do the consistent conversion? 2) How do I (find) all instances, because this "date" is not an actual attribute, is it a calculated value which changes depending on the two associated models of Contact and Email. Thanks.

• t-sql recursive query

  - by stackoverflowuser

  Based on an existing table I used CTE recursive query to come up with following data. But failing to apply it a level further. Data is as below id name parentid -------------------------- 1 project 0 2 structure 1 3 path_1 2 4 path_2 2 5 path_3 2 6 path_4 3 7 path_5 4 8 path_6 5 I want to recursively form full paths from the above data. Means the recursion will give the following output. FullPaths ------------- Project Project\Structure Project\Structure\Path_1 Project\Structure\Path_2 Project\Structure\Path_3 Project\Structure\Path_1\path_4 Project\Structure\Path_2\path_5 Project\Structure\Path_3\path_6 Thanks

• Why should I reuse XmlHttpRequest objects?

  - by Xavi

  From what I understand, it's a best practice to reuse XmlHttpRequest objects whenever possible. Unfortunately, I'm having a hard time understanding why. It seems like trying to reuse XHR objects can increase code complexity, introduce possible browser incompatibilities, and lead to other subtle bugs. After researching this question for a while, I did come up with a list of possible explanations: Fewer objects created means less garbage collecting Reusing XHR objects reduces the chance of memory leaks The overhead of creating a new XHR object is high The browser is able to perform some sort of network optimization under hood But I'm not sure if any of these reasons are actually valid. Any light you can shed on this question would be much appreciated.

• How to allow for modular development while still running in same JVM?

  - by Marcus

  Our current app runs in a single JVM. We are now splitting up the app into separate logical services where each service runs in its own JVM. The split is being done to allow a single service to be modified and deployed without impacting the entire system. This reduces the need to QA the entire system - just need to QA the interaction with the service being changed. For interservice communication we use a combination of REST, an MQ system bus, and database views. What I don't like about this: REST means we have to marshal data to/from XML DB views couple the systems together which defeats the whole concept of separate services MQ / system bus is added complexity There is inevitably some code duplication between services You have set up n JBoss server configurations, we have to do n number of deployments, n number of set up scripts, etc, etc. Is there a better way to structure an internal application to allow modular development and deployment while allowing the app to run in a single JVM (and achieving the associated benefits)?

• How do I route watir through a proxy pragmatically?

  - by feydr

  I'm trying to route watir through a proxy pragmatically -- this means within the script I'd like to change my proxy dynamically before launching the browser. Here's what I've tried so far (and so far am failing): I'm running chrome and lucid lynx ubuntu. I chose TREX cause I thought watir might be making use of PROXY or something. I rewrote /usr/bin/google-chrome as: #!/bin/bash /opt/google/chrome/chrome --proxy-server="$TREX" $@ The reason I'm passing in the environment variable to proxy-server rather than http_proxy is because I never could get http_proxy to work as is anyways then I did a simple: require 'rubygems' require 'watir-webdriver' ENV['TREX'] = "XX.XX.XX.XX:YY" browser = Watir::Browser.new(:chrome) browser.goto("http://mysite.com") Anyways, what is happening here is that it is forwarding me to the login page of the proxy rather than just forwarding the request. What am I missing here? I feel like I'm pretty close.

• What explains the term orthogonal in a more non-nerd fashion?

  - by dontWatchMyProfile

  For example: Cardinality and optionality are orthogonal properties of a relationship. You can specify that a relationship is optional, even if you have specified upper and/or lower bounds. This means that there do not have to be any objects at the destination, but if there are then the number of objects must lie within the bounds specified. What exactly does "orthogonal" mean? I bet it's just a fancy soundig nerd-style word for something that could be expressed a lot easier to understand for average people ;) From wikipedia: In mathematics, two vectors are orthogonal if they are perpendicular, i.e., they form a right angle. The word comes from the Greek ????? (orthos), meaning "straight", and ????a (gonia), meaning "angle". Anyone?

• Create slide-in notifications à la Outlook in Windows with .NET

  - by Draak

  I am using .NET and am creating a desktop app/service that will display notifications in the corner of my Desktop when certain events are triggered. I don't want to use a regular Message Box b/c that would be too intrusive. The notifications would slide into view and then fade out after a few seconds. I am thinking of something that will act very much like the Outlook alerts that one gets when a new message arrives. The question is: Should I use WPF for this? I've never done anything with WPF but will happily try it if that's best means to the end. Is there a way to accomplish this with regular .NET libraries?

• C#: Making sure parameter has attribute

  - by slayerIQ

  I have an attribute lets call it SomeAttribute and a class i need to make sure the class is passed a type which has SomeAttribute. So this is how i do it now: public class Test() { public Test(SomeType obj) { if(!obj.GetType().IsDefined(typeof(SomeAttribute), false)) { throw new ArgumentException("Errormessage"); } } } But this means that i don't get any errors at compile time but somewhere at runtime, if obj does not have the attribute. Is there a way to specify in the method declaration that the parameter must have some attribute ? So i get errors i compile time when using the wrong parameters.

• Copying a massive databse for local ruby on rails development?

  - by tesmar

  Hi guys, There is a massive database (GB) that I am working with now and all of the previous development has been done on a slicehost slice. I am trying to get ready for more developers to come in and work so I need each person to be able to setup his own machine for development, which means potentially copying this database. Selecting only the first X rows in each table to cut size could be problematic for data consistency. Is there any way around this, or is a 1 hour download for each developer going to be necessary? And beyond that, what if I need to copy the production DB down for dev purposes in the future? Sincerely, Tyler

• Do not use IE browser settings when using a proxy with Indy

  - by JD

  Hi At one of our customer sites, we have a Delphi 2007 application that makes a number of HTTPS requests using indy components. All requests are made using the proxy settings the client provides. For this to work, in IE we have to put the URL's in the trusted zones section. After a month due to security settings the trusted zones are cleared. This means we have to re-add the URLs again to make our application work. Is there a way of bypassing IE settings or using a client side HTTP stack so we do not go through the browser to make https requests? JD

• Does replacing statements by expressions using the C++ comma operator could allow more compiler opti

  - by Gabriel Cuvillier

  The C++ comma operator is used to chain individual expressions, yielding the value of the last executed expression as the result. For example the skeleton code (6 statements, 6 expressions): step1; step2; if (condition) step3; return step4; else return step5; May be rewritten to: (1 statement, 6 expressions) return step1, step2, condition? step3, step4 : step5; I noticed that it is not possible to perform step-by-step debugging of such code, as the expression chain seems to be executed as a whole. Does it means that the compiler is able to perform special optimizations which are not possible with the traditional statement approach (specially if the steps are const or inline)? Note: I'm not talking about the coding style merit of that way of expressing sequence of expressions! Just about the possible optimisations allowed by replacing statements by expressions.

• ASP.Net: Finding the cause of OutOfMemoryExpcetions

  - by Keith Bloom

  I trying to track down the cause of an OutOfMemory for a website. This site has ~12,000 .aspx pages and the last time it crashed I captured a memory dump using adplus. After some investigation I found a lot of heap fragmentation, there are around 100MB of Free blocks which can't be assigned. Digging deeper one of the Large Object Heaps is fragmented and the causes seems to be String interning as described [here][1] Could this be caused by the number of pages in the site? As they are all compiled they sit in memory and by looking at the dump they are interned and PINNED which I think means they stick around for a while. I would find this odd as there are many sites with more pages, but dynamic compilation could account for the growth in memory. What other methods are there for finding the cause of the memory leak? I have tried to capture a dump using adplus in hang mode but this fails and the IIS worker process get recycled. [1]: • http://stackoverflow.com/questions/686950/large-object-heap-fragmentation

• How to configure AutoMapper if not ASP.net Application?

  - by alex

  I'm using AutoMapper in a number of projects within my solution. These projects may be deployed independantly, across multiple servers. In the documentation for AutoMapper it says: If you're using the static Mapper method, configuration only needs to happen once per AppDomain. That means the best place to put the configuration code is in application startup, such as the Global.asax file for ASP.NET applications. Whilst some of the projects will be ASP.net - most of these are class libraries / windows services. Where should I be configuring my mappings in this case?

• Linux and I/O completion ports?

  - by someguy

  Using winsock, you can configure sockets or seperate I/O operations to "overlap". This means that calls to perform I/O are returned immediately, while the actual operations are completed asynchronously by separate worker threads. Winsock also provides "completion ports". From what I understand, a completion port acts as a multiplexer of handles (sockets). A handle can be demultiplexed if it isn't in the middle of an I/O operation, i.e. if all its I/O operations are completed. So, on to my question... does linux support completion ports or even asynchronous I/O for sockets?
