• How to enable a Web portal-based enterprise platform on different domains and hosts without customization [on hold]

  - by S.Jalali

  At Coscend, a cloud and communications software product company, we have built a Web portal-based collaboration platform that we like to host on five different Windows- and Linux-based servers in different hosting environments that run Web servers. Each of these Windows and Linux servers has a different host name and domain name (and IP address). Our team would appreciate your guidance on: (1) Is there a way to implement this Web portal-based platform on these Linux and Windows servers without customizing the host name, domain name and IP address for each individual instance? (2) Is there a way to create some variables using JavaScript for host name and domain name and call them from the different implementations? If a reference to the host/domain names occurs on hundreds of our pages, the variables or objects would replace that. (3) This is part of making these JavaScript modules portable and re-usable for different environments and instances. The portal is written in JavaScript that is embedded in HTML5 and padded with CSS3. Other technologies include Flash, Flex, PostgreSQL and MySQL.

• Does having a higher paid technical job mean you do not get to code any more?

  - by c_maker

  I work at a large company where technical people fall roughly in one of these categories: A developer on a scrum team who develops for a single product and maybe works with other teams that are closely related to the product. An architect who is more of a consultant on multiple teams (5-6) and tries to recognize commonalities between team efforts that could be abstracted into libraries (architects do not write the library code, however). This architect also attends many meetings with management and attempts to set technical direction. In my company the architect role is where most technical people move into as the next step in their career. My questions are: Do most companies work such a way that their highest paid technical people are far removed from writing code? Is this a natural tendency for a developer's career? Can a developer have it all (code AND set direction?)

• Staying concentrated during small pauses [migrated]

  - by 9000

  My workflow includes some steps that make me wait for 0.5 to 2 minutes to complete: long remote git operations, creating / rebooting an instance in the cloud, etc. It's safe to assume that these operations cannot be made any faster. The resulting delays are the biggest flow-breakers for me. These are too long to just sit and stare at the progress indicators, but too short to take a walk and grab a coffee. Temptation to check some websites is big, and it's often a road to 20-30 minutes of procrastination + the time to get into the flow again. What are your coping strategies?

• Checking All Checkboxes in a GridView Using jQuery

  In May 2006 I wrote two articles that showed how to add a column of checkboxes to a GridView and offer the ability for users to check (or uncheck) all checkboxes in the column with a single click of the mouse. The first article, Checking All CheckBoxes in a GridView, showed how to add "Check All" and "Uncheck All" buttons to the page above the GridView that, when clicked, checked or unchecked all of the checkboxes. The second article, Checking All CheckBoxes in a GridView Using Client-Side Script and a Check All CheckBox, detailed how to add a checkbox to the checkbox column in the grid's header row that would check or uncheck all checkboxes in the column.

• What are the challenges and benefits of writing games with a functional language?

  - by McMuttons

  While I know that functional languages aren't the most commonly used for game writing, there are a lot of benefits associate with them that seem like they would be interesting in any programming context. Especially the ease of parallelization I would think could be very useful as focus is moving toward more and more processors. Also, with F# as a new member of the .NET family, it can be used directly with XNA, for example, which lowers the threshold quite a bit, as opposed to going with LISP, Haskell, Erlang, etc. If anyone has experience writing games with functional code, what has turned out to be the positives and negatives? What was it suited for, what not? Edit: Finding it hard to decide that there's a single good answer for this, so it's probably better suited as a community wiki post.

• Looking for feedback on design pattern for simple 2D environment

  - by Le Mot Juiced

  I'm working in iOS. I am trying to make a very simple 2D environment where there are some basic shapes you can drag around with your finger. These shapes should interact in various ways when dropped on each other, or when single-tapped versus double-tapped, etc. I don't know the name for the design pattern I'm thinking of. Basically, you have a bunch of arrays named after attributes, such as "double-tappable" or "draggable" or "stackable". You assign these attributes to the shapes by putting the shapes in the arrays. So, if there's a double-tap event, the code gets the location of it, then iterates through the "double-tappable" array to see if any of its members are in that location. And so on: every interactive event causes a scan through the appropriate array or arrays. It seems like that should work, but I'm wondering if there's a better pattern for the purpose.

• How compilers know about other classes and their properties?

  - by OnResolve

  I'm writing my first programming language that is object orientated and so far so good with create a single 'class'. But, let's say I want to have to classes, say ClassA and ClassB. Provided these two have nothing to do with each other then all is good. However, say ClassA creates a ClassB--this poses 2 related questions: -How would the compiler know when compiling ClassA that ClassB even exists, and, if it does, how does it know it's properties? My thoughts thus far had been: instead of compiling each class at a time (i.e scan, parse and generate code) each "file (not really file, per se, but a "class") do I need to scan + parse each first, then generate code for all?

• Do any database "styles" use discrete files for their tables?

  - by Brad

  I've been talking to some people at work who believe some versions of a database store their data in discrete tables. That is to say you might open up a folder and see one file for each table in the database then several other supporting files. They do not have a lot of experience with databases but I have only been working with them for a little over a half year so I am not a canonical source of info either. I've been touting the benefits of SQL Server over Access (and before this, Access over Excel. Great strides have been made :) ). But, other people were of the impression that the/one of the the benefit(s) of using SQL Server over Access was that all the data was not consolidated down into one file. Yet, SQL Server packs everything into a single .mdf file (plus the log file). My question is, is there an RDBMS which holds it's data in multiple discrete files instead of one master file? And if the answer is yes, why do it one way over the other?

• Creating thumbnails with the same name as the pictures

  - by Duby

  Please, here is my little code for creating thumbnails of pictures saved in a folder named 'pictures', and saving them in another folder named 'thumbs'. ! /bin/bash for i in *.jpg do convert -thumbnail 100 pictures/$i thumbs/$i done However, there two things the program doesn't do: 1) It does not retain the name of the pictures in the thumbnail. For instance, I would want it to generate a thumbnail with the name pic.jpg for a picture named pic.jpg 2) Also, when I run the program, i don't want it to generate the thumbnail for a picture it has already generated its thumbnail, unless that picture has been modified. Any help will be very much appreciated. Thank you

• The life saver HttpContext.Current.Items["ParameterName"]

  - by MoezMousavi

  I got stocked passing parameter to one master page for some reasons, seems the page lifecycle and dynamic loading of the master pages has got some issues with defining public properties in the masterpage within my project. It did not set my values and as a result, properties became useless. A collegue just mentioned using HttpContext. have a look what  MSDN saying "Encapsulates all HTTP-specific information about an individual HTTP request" http://msdn.microsoft.com/en-us/library/system.web.httpcontext.aspx HttpContext.Current.Items["ParameterName"] Also, Page.Items could do the same thing. Page.Items, "Gets a list of objects stored in the page context" http://msdn.microsoft.com/en-us/library/system.web.ui.page.items.aspx as your master page and content page are rendered as a single document anyway.

• Has the Appindicator or GtkMenu API changed in Saucy?

  - by marxjohnson

  I've written a custom application indicator, which isn't working properly on saucy. The menu is initialised with a few items, then updates regularly, adding or removing menu items. This worked fine <13.10, but on 13.10, the line that adds the menu to the indicator produces the following warning: Warning: /build/buildd/glib2.0-2.38.0/./gobject/gsignal.c:2475: signal 'child-added' is invalid for instance '0x24390e0' of type 'GtkMenu' self.ind.set_menu(self.menu) And the items added to the menu subsequently dont appear. A bug has been filed against several indicators for the same problem, but it's not clear to me whether this is a problem with the indicators as a result of an API change, or a bug in the GTK or Appindicator libraries. Does anyone know?

• Is it safe to run multiple XNA ContentManager instances on multiple threads?

  - by Boinst

  My XNA project currently uses one ContentManager instance, and one dedicated background thread for loading all content. I wonder, would it be safe to have multiple ContentManager instances, each in it's own dedicated thread, loading different content at the same time? I'm prompted to ask this question because this article makes the following statement: If there are two textures created at the same time on different threads, they will clobber the other and you will end up with some garbage in the textures. I think that what the author is saying here, is that if I access one ContentManager simultaneously on two threads, I'll get garbage. But what if I have separate ContentManager instances for each thread? If no-one knows the answer already from experience, I'll go ahead and try it and see what happens.

• What kind of performance issues does multiple instances of the exact same object have on a game?

  - by lggmonclar

  I'm fairly new to programming, and I've pretty much learned all the things I know on the go, while working on projects. The problem is that there some things that I just don't know where to begin searching. My question is about performance, and how can multiple instances of the same object affect it -- Specifically, I'm talking about XNA's "GraphicsDevice" class. I have it instanced on four different parts of my game, and in three of those, the object has the exact same values for all the attributes. So, in that case, should I be using the same instance of GraphicsDevice, passing it as a parameter, even if I use it in different classes? I apologize if the question seems redundant, but like I said, I've taught myself most of what I know, so there are quite a few "holes" in my learning process.

• Web Search for a Hard Drive

  - by zecougar

  Here is the situation. Our organization has a fair amount of data in the form of documents, images, videos stored on a intranet server. We need to be able to expose these documents via some sort of search functionality on the intranet. Provide some mechanism to organize and tag the documents on hard disk. Ideally we'd also like to provide a unified search across documents on the google apps for business instance that we have. Any ideas on how to approach this problem ?

• Interface hierarchy design for separate domains

  - by jerzi

  There are businesses and people. People could be liked and businesses could be commented on: class Like class Comment class Person implements iLikeTarget class Business implements iCommentTarget Likes and comments are performed by a user(person) so they are authored: class Like implements iAuthored class Comment implements iAuthored People's like could also be used in their history: class history class Like implements iAuthored, iHistoryTarget Now, a smart developer comes and says each history is attached to a user so history should be authored: interface iHistoryTarget extends iAuthored so it could be removed from class Like: class Person implements iLikeTarget class Business implements iCommentTarget class Like implements iHistoryTarget class Comment implements iAuthored class history interface iHistoryTarget extends iAuthored Here, another smart guy comes with a question: How could I capture the Authored fact in Like and Comment classes? He may knows nothing about history concept in the project. By scalling these kind of functionallities, interfaces may goes to their encapsulated types which cause more type strength, on the other hand explicitness suffered and also code end users will face much pain to process. So here is the question: Should I encapsulate those dependant types to their parent types (interface hierarchies) or not or explicitly repeat each type for every single level of my type system or ...?

• Java Preferential Treatment

  - by Jay

  I have icedtea6-plugin installed on my Ubuntu box. The weird thing is, when I am browsing the internet, certain website are able to use the Java and some websites are not. For instance, I am able to log in to my bank at nordea.dk. They use a Java applet to authenticate the user. But when I try to use keepvid.com, it says "Loading Java Applet". And then after a minute or two it says "Error: Please click here to download Java. If you already have Java, please restart your browser and try again." The thing is I've restarted my computer, closed and opened my browser(chromium) and none of it seems to help. Could someone please point me in the right direction to solve this problem? Thanks.

• Clicking on application launcher starts another window. What should I do?

  - by MMA

  If I remember correctly, clicking on the application in launcher started the application if it was not already open and focused on the application if it was already open. Previously, I had to middle click to start another instance. But, recently, whenever I click in the launcher, a new application window is started, irrespective of whether one is already open or not. What should I do? A bug? Or a new feature? I am using 12.04 LTS and 12.10 in two machines. Both fully updated. Both are showing the same behaviour.

• How productive do you think/know you are?

  - by leinad

  I'm a good programmer, and I know it. Yet, I often find myself thinking that I actually work very slowly. I worked on a feature from Monday to Wednesday this week. On the way home on Wednesday I was wondering what had taken so long. It seemed like I should have been done in a single day but I wasted three to finish it up. This is not the first time I had this feeling. Do you ever feel this or the opposite?

• Cocos 2D - Hold down CCMenuItem

  - by Will Youmans

  I am using the following code to move a CCSprite left and right. -(id)init{ CCMenuItemImage * moveLeftButton = [CCMenuItemImage itemFromNormalImage:@"Move Left Button.png" selectedImage:@"Move Left Button.png" target:self selector:@selector(moveLeftVoid:)]; } -(void)moveLeftVoid{ id moveLeft = [CCMoveBy actionWithDuration:.3 position:ccp(-10, 0)]; [_mainSprite runAction:moveLeft]; } This does work, but only as a single tap. What I want for the CCSprite to move continously in that direction when the CCMenuItem is held down. Then when it's released the character stops moving. If you need to see more code, please just ask. :) Thanks

• What are the pros and cons of Coffeescript?

  - by Philip

  Of course one big pro is the amount of syntactic sugar leading to shorter code in a lot of cases. On http://jashkenas.github.com/coffee-script/ there are impressive examples. On the other hand I have doubts that these examples represent code of complex real world applications. In my code for instance I never add functions to bare objects but rather to their prototypes. Moreover the prototype feature is hidden from the user, suggesting classical OOP rather than idiomatic Javascript. The array comprehension example would look in my code probably like this: cubes = $.map(list, math.cube); // which is 8 characters less using jQuery...

• C++ linkage error . What am I doing wrong ? [migrated]

  - by nashmaniac

  So, this is the first time I actually separated a single program into a header and two .cpp files . But I think I am getting an linkage error . Heres how the directory looks . (heres a link to my image I dont have enough rep to post image in the question) http://i.stack.imgur.com/sbT4V.png The main.cpp is my main source file where all the calling functions and other important stuff goes . In functions.cpp I have all my functions , in the coordin.h file I have the function prototypes and structures and Constants . Everything is ok no typo nothing I have checked everything . But I am getting an undefined reference to function error. I have included the coordin.h file too . Do you think the functions.cpp file needs to go somewhere else I mean is the compiler not looking inside that file ? Thanks !

• Rebuilding system databases in 2008 R2

  - by TiborKaraszi

  All my attempts so far to rebuild the system databases in 2008 R2 has failed. I first tried to run setup from below path: C:\Program Files\Microsoft SQL Server\100\Setup Bootstrap\Release But above turns out to be the 2008 setup program, not 2008R2 setup; even though I have no 2008 instanced installed (I have only R2 instances installed). Apparently, the 2008 setup program does a version check of the instance to be rebuilt and since it is > 10.50.0, the rebuild fails. Books Online for R2 the section...(read more)

• UEFI hardware and dual booting with windows

  - by user39803

  I've been struggling for 3 days trying to dual boot Ubuntu 11.10 and Windows 7. I want to use an SSD for my Ubuntu installation and an hdd for Windows. I realized that I have to install windows first and then ubuntu, and so I did that. When I first install windows it boots fine from my hdd, but when I add ubuntu on my ssd and restart, I get a black screen with a blinking cursor. I've read many forums where this is asked but haven't found a single solution that works. I've tried boot repair. It told me to make a fat ESP partition and I did that as well but it still doesn't work. I'm a noob and any suggestions would be really appreciated.

• What amount of PHP memory usage is reasonable for multiple WordPress sites? [closed]

  - by John

  It seems like I've been plagued with memory usage issues most of the time I've been blogging (7 years). I upgraded my hosting to a HostGator VPS and still seem to have issues. I have about a dozen WP 3.4.2 sites running within a single account. Each has a separate installation. I finally installed TPC! Memory Usage within one of my WP installs to see what was going on. The memory usage just standing still is on the order of 40 MB. This seems high, but I don't know. What would be a reasonable memory usage for these WP installs? Do I need to take other things into account, or am I even looking at it the right way?
