• Internationalization messages based in views or in model entities

  - by SJuan76

  I have a small webapp in java and I am adding the internationalization support, replacing texts with labels that are defined in dictionary files. While some texts are obviously unique to each view (v.g. the html title), other refer to concepts from the model (v.g. a ticket, the location or status of such ticket, etc.) As usual, some terms will appear many times in different locations (vg, in both the edition page and in the search page and in the listings I have a "ticketLocation" label). My question is: can I organize the labels around the model concepts (so I have a ticket.location label and I use it everywhere such field is labeled) or should I make a different label for each (so form.ticketLocation and filter.ticketLocation and list.ticketLocation). I would go for the first option; I have searched for tips and the only thing that I see that could hinder me is due to the length of the string disrupting the design, and even for that I would prefer having to add a ticket.locationShort for places where there is not much space. What is your opinion/tips/experience?

• Is spreading code with refactoring comments a good idea?

  - by Uooo

  I am working on a "spaghetti-code" project, and while I am fixing bugs and implementing new features, I also do some refactoring in order to make the code unit-testable. The code is often so tightly coupled or complicated that fixing a small bug would result in a lot of classes being rewritten. So I decided to draw a line somewhere in the code where I stop refactoring. To make this clear, I drop some comments in the code explaining the situation, like: class RefactoredClass { private SingletonClass xyz; // I know SingletonClass is a Singleton, so I would not need to pass it here. // However, I would like to get rid of it in the future, so it is passed as a // parameter here to make this change easier later. public RefactoredClass(SingletonClass xyz) { this.xyz = xyz; } } Or, another piece of cake: // This might be a good candidate to be refactored. The structure is like: // Version String // | // +--> ... // | // +--> ... // | // ... and so on ... // Map map = new HashMap<String, Map<String, Map<String, List<String>>>>(); Is this a good idea? What should I keep in mind when doing so?

• How "commercially savvy" should software developers be? [closed]

  - by mattnz

  I have been watching answers to many questions on this site, and have come to the conclusion that commercial pragmatism does not factor into many software development discussions. As a result, I seriously wonder at the commercial skills within the industry, specifically the ability to deliver projects on time and to a budget. I see no indication from the site that commercially successful project delivery is a serious concern, yet the industry has a reputation for poor performance in this. Rarely, if ever, does the cost of time factor into discussions. I have never seen concepts such as opportunity cost, time to market, competitive advantage or cash flow mentioned, let alone discussed in technical answers to questions. How can you answer virtually any question without understanding the commercial background on which it is asked? Even Open source projects have a need to operate efficiently and deploy their limited resources to providing the most value for effort. Typically small start-ups have cash flow issues that outweigh longevity concerns, yet they are typically still advised to build for a future they probably won’t have if they do. Is it fair to say that these problems are solely the Managers and Project managers to solve, or are we, as developers, also responsible for ensuring successful on time, within budget delivery of projects, even if those budgets do not allow use to achieve engineering excellence?

• How to handle the fear of future licensing issues of third-party products in software development?

  - by Ian Pugsley

  The company I work for recently purchased some third party libraries from a very well-known, established vendor. There is some fear among management that the possibility exists that our license to use the software could be revoked somehow. The example I'm hearing is of something like a patent issue; i.e. the company we purchased the libraries from could be sued and legally lose the ability to distribute and provide the libraries. The big fear is that we get some sort of notice that we have to cease usage of the libraries entirely, and have some small time period to do so. As a result of this fear, our ability to use these libraries (which the company has spent money on...) is being limited, at the cost of many hours worth of development time. Specifically, we're having to develop lots of the features that the library already incorporates. Should we be limiting ourselves in this way? Is it possible for the perpetual license granted to us by the third party to be revoked in the case of something like a patent issue, and are there any examples of something like this happening? Most importantly, if this is something to legitimately be concerned about, how do people ever go about taking advantage third-party software while preparing for the possibility of losing that capability entirely? P.S. - I understand that this will venture into legal knowledge, and that none of the answers provided can be construed as legal advice in any fashion.

• How to quickly search through a very large list of strings / records on a database

  - by Giorgio

  I have the following problem: I have a database containing more than 2 million records. Each record has a string field X and I want to display a list of records for which field X contains a certain string. Each record is about 500 bytes in size. To make it more concrete: in the GUI of my application I have a text field where I can enter a string. Above the text field I have a table displaying the (first N, e.g. 100) records that match the string in the text field. When I type or delete one character in the text field, the table content must be updated on the fly. I wonder if there is an efficient way of doing this using appropriate index structures and / or caching. As explained above, I only want to display the first N items that match the query. Therefore, for N small enough, it should not be a big issue loading the matching items from the database. Besides, caching items in main memory can make retrieval faster. I think the main problem is how to find the matching items quickly, given the pattern string. Can I rely on some DBMS facilities, or do I have to build some in-memory index myself? Any ideas? EDIT I have run a first experiment. I have split the records into different text files (at most 200 records per file) and put the files in different directories (I used the content of one data field to determine the directory tree). I end up with about 50000 files in about 40000 directories. I have then run Lucene to index the files. Searching for a string with the Lucene demo program is pretty fast. Splitting and indexing took a few minutes: this is totally acceptable for me because it is a static data set that I want to query. The next step is to integrate Lucene in the main program and use the hits returned by Lucene to load the relevant records into main memory.

• Why is text on my TV monitor all grainy?

  - by searchfgold6789

  I have successfully installed the Catalyst drivers and hooked up my 1080p TV to the Radeon HD 5750's HDMI port and now it is working. There only seems to be one issue - most images appear OK, at least to my eyes, but text is grainy and difficult to read (not sure how well it can be seen in the picture): It works fine with a smaller screen, and hopefully you can see it with the new pictures which are only slightly better, but images are rendered a little funny too. Changing antialiasing does nothing and changing the refresh rate only makes a slight change if any. The small monitor I have works fine. Smaller resolutions such as 1024x768 look OK but are the wrong aspect ratio. I have tried renaming the input mode on the TV to "PC", and that helped... a little bit. Also, I tried a different PC with the same result. Messing around extensively with the ATI Catalyst Control Center also did not help. I am wondering if there is anything else I can try to increase the quality so it is more usable.

• Bad previous code. To fix or not to fix?

  - by Viniyo Shouta

  As a freelancer programmer I am often asked to edit part of an application source code in order to add functionalities, fix bugs etc. While I'm on my adventure journey to study the source to do what I'm asked correctly I run into code like: World::User* GetWorld() { map<DWORD,World*>::iterator it = mapWld.find( m_userWorldId ) if( it != mapWld.end() ) return &it->second; return NULL; } if( pUser->GetWorld()->GetId() == 250 ) If I investigate further I end up finding that the DWORD class member of User, userWorldId can be a value non-found in the map mapWld, which will lead to a casuality as also known as crash! The obviously valid way to do it is: World* pWorld = pUser->GetWorld(); if( pWorld && pWorld->GetId() == 250 )//... Sometimes when it's something just 'small' I end up sort of 'fixing' it. But sometimes when I'm on a 500 thousand line source code and this kind of code is everywhere there is no much can do. The question is if it's politically correct to fix some of these things. Think of it; You are not paid to fix it. Perhaps you think it's right, but it was necessarily done that way for some reason and you should not be messing with it. You do not have authorization, you do not own the source and none of the copyrights belong to you. You have authorization to edit issues accordingly to the owners but you're in a hurry, you have many other projects to do, it's the end of the month, you must pay the bills. Sincerely, I think of it as seeing an animal die from a disease in front of you, you have the cure in your hands but you do nothing. What is the best to do in this scenario?

• How to do integrated testing?

  - by Enthusiastic Programmer

  So I have been reading up on a lot of books surrounding testing. But all the books I've read have the same flaws. They will all tell you the definitions of testing. But I have not found a single book that will guide you into integration testing (or pretty much anything higher then unit testing). Is integration testing that elusive or am I reading the wrong books? I'm a hands on person, so I would appreciate it if someone could help me with a simple program: Let's say you need to make some sort of calculation program that calculates something (doesn't matter what) and exports it to *.txt file. Let's assume we use the Model View Controller design principle. And one class for the actual calculating which you'll use in the model and one for writing the textfile. So: View = Controller = Model = CalculationClass, FileClass So for unittesting: You'd test the calculationClass, I'd personally focus most of my unit tests there. And less time on unit testing the view/controller/FileClass. I personally wouldn't see the use of unittesting those unless you want a really robust program. Integration testing: Now this is where I run into a wall. What would I have to test to call it an integration test? I could stub the view and feed the controller data which it would pass on to the model and so forth. And then check what the view gets back in the end. But ... Couldn't I just run the (in this case small) program then and test it manually? Would this be considered a integration test too, or does it have to be automated? Also, can I check multiple items to see if they are correct? I cannot seem to find any book that offers a hands on approach to methods of integration testing.

• How to correct a junior, but encourage him to think for himself? [closed]

  - by Phil

  I am the lead of a small team where everyone has less than a year of software development experience. I wouldn't by any means call myself a software guru, but I have learned a few things in the few years that I've been writing software. When we do code reviews I do a fair bit of teaching and correcting mistakes. I will say things like "This is overly complex and convoluted, and here's why," or "What do you think about moving this method into a separate class?" I am extra careful to communicate that if they have questions or dissenting opinions, that's ok and we need to discuss. Every time I correct someone, I ask "What do you think?" or something similar. However they rarely if ever disagree or ask why. And lately I've been noticing more blatant signs that they are blindly agreeing with my statements and not forming opinions of their own. I need a team who can learn to do things right autonomously, not just follow instructions. How does one correct a junior developer, but still encourage him to think for himself? Edit: Here's an example of one of these obvious signs that they're not forming their own opinions: Me: I like your idea of creating an extension method, but I don't like how you passed a large complex lambda as a parameter. The lambda forces others to know too much about the method's implementation. Junior (after misunderstanding me): Yes, I totally agree. We should not use extension methods here because they force other developers to know too much about the implementation. There was a misunderstanding, and that has been dealt with. But there was not even an OUNCE of logic in his statement! He thought he was regurgitating my logic back to me, thinking it would make sense when really he had no clue why he was saying it.

• ADF Logging In Deployed Apps

  - by Duncan Mills

  Harking back to my series on using the ADF logger and the related  ADF Insider Video, I've had a couple of queries this week about using the logger from Enterprise Manager (EM). I've alluded in those previous materials to how EM can be used but it's evident that folks need a little help.  So in this article, I'll quickly look at how you can switch logging on from the EM console for an application and how you can view the output.  Before we start I'm assuming that you have EM up and running, in my case I have a small test install of Fusion Middleware Patchset 5 with an ADF application deployed to a managed server. Step 1 - Select your Application In the EM navigator select the app you're interested in: At this point you can actually bring up the context ( right mouse click) menu to jump to the logging, but let's do it another way.  Step 2 - Open the Application Deployment Menu At the top of the screen, underneath the application name, you'll find a drop down menu which will take you to the options to view log messages and configure logging, thus: Step 3 - Set your Logging Levels  Just like the log configuration within JDeveloper, we can set up transient or permanent (not recommended!) loggers here. In this case I've filtered the class list down to just oracle.demo, and set the log level to config. You can now go away and do stuff in the app to generate log entries. Step 4 - View the Output  Again from the Application Deployment menu we can jump to the log viewer screen and, as I have here, start to filter down the logging output to the stuff you're interested in.  In this case I've filtered by module name. You'll notice here that you can again look at related log messages. Importantly, you'll also see the name of the log file that holds this message, so it you'd rather analyse the log in more detail offline, through the ODL log analyser in JDeveloper, then you can see which log to download.

• Using "gedit", a string of errors occours

  - by Kumuluzz

  I'm trying to program some small programs in C in terminal and gedit. But everytime i use gedit then a string of errors occours. When i open a new file nothing happens. But in the exact same moment i save the file, then a string of erros coour. Also if i open an already existing file (not a new one), then when the gedit window opens the old file all the lines of errors are writen. In both cases in less than a second and nothing more happens. An example to the error: "error: line 35272: 0 is wrong flag id". They are all similar to this, except the line number is different. There are like 50 of them. I'm running 11.10, just installed it a couple of days again (yes, i'm a newbie) and i've updated all the files recently. I've tried reinstalling gedit via: sudo apt-get --reinstall install gedit It kinda made it worse, now a lot of the lines are shown twice. So now it goes (this is a copy of the first lines of error): error: line 6787: 0 is wrong flag id error: line 10034: 0 is wrong flag id error: line 10034: 0 is wrong flag id error: line 11351: 0 is wrong flag id error: line 11351: 0 is wrong flag id error: line 11849: 0 is wrong flag id error: line 11849: 0 is wrong flag id error: line 15609: 0 is wrong flag id error: line 15609: 0 is wrong flag id error: line 19814: 0 is wrong flag id

• How to structure reading of commands given at a(n interactive) CLI prompt?

  - by Anto

  Let's say I have a program called theprogram (the marketing team was on strike when the product was to be named). I start that program by typing, perhaps not surprisingly, the program name as a command into a command prompt. After that, I get into a loop (from the users standpoint, an interactive command-line prompt), where one command will be read from the user, and depending on what command was given, the program will execute some instructions. I have been doing something like the following (in C-like pseudocode): main_loop{ in=read_input(); if(in=="command 1") do_something(); else if(in=="command 2") do_something_else(); ... } (In a real program, I would probably encapsulate more things into different procedures, this is just an example.) This works well for a small amount of commands, but let's say you have 100, 1000 or even 10 000 of them (the manual would be huge!). It is clearly a bad idea to have 10 000 ifs and else ifs after each other, for instance, the program would be hard to read, hard to maintain, contain a lot of boilerplate code... Yeah, you don't want to do that, so what approach would you recommend me to use (I will probably never use 10 000 commands in a program, but the solution should, at least preferably, be able to scale to that kind of massive (?) problems. The solution doesn't have to allow for arguments to the commands)?

• What service or software should I use to serve advertising on a site with about 120k monthly page views?

  - by JasonBirch

  I have a site that is generating about 120k monthly page views and is being hosted on a shared FreeBSD server where I have access to PHP and MySQL. I am using some custom PHP server-side scripts that give each of my ad networks (AdSense, Tribal Fusion, etc) an adjustable percentage of impressions in each of the ad positions on my pages. I am looking for a better way of managing and measuring the delivery of these ads, and would also like to be able to take direct placements and provide statistics to the clients. I am looking at options including OpenX self-hosted, OpenX community, and Google DoubleClick for Publishers Small Business (DFP), but am having difficulty determining which one will best meet my needs. They all seem to have pretty steep learning curves compared to my simple scripts. What I have taken away so far as the benefit of self-hosting is that I don't have to pay for the service if I exceed a maximum number of ad impressions, while both OpenX Community and DFP have free impression limits. Of course, if I was doing those kind of numbers I'd need to upgrade my hosting account, but I'm not sure even at that point whether it would be cheaper to serve the ads myself than pay for a premium service. Apart from this, I really need insights into what features differentiate these services, why I might want to choose one over another, and if there are any other competing products or service of the same quality that I should look into. Answers from webmasters who have used both (or all three) services and can talk to usability and ease of ad management would be highly appreciated.

• How do I force the system to look for new sound devices?

  - by John Zeringue

  I have a small flat screen TV (Toshiba) that I often connect via HDMI to my laptop (an HP Pavilion dv4) and use as a computer monitor. When I do this, I prefer to use the TV's speakers, particularly when I'm watching video, because the sound quality is much better. However, when I connect the HDMI cable after turning on my computer (rather than having it plugged in before booting up), Sound Settings does not list the TV as an output device, and I am forced to reboot. I was curious if there is an easier solution to this, perhaps a CLI command to check for new sound outputs. Does anyone know of something like this or have another solution? To clarify, I believe this is a software problem. The HDMI always works, and I can switch my desktop over to the TV at any time. The issue is that, if the HDMI wasn't connected during start up, the TV will not appear as an output option in the Sound Settings GUI. So, unless I'm mistaken, my question is not HDMI specific, but rather a general usage question about manipulating sound settings from the command line.

• How to persuade C fanatics to work on my C++ open source project?

  - by paperjam

  I am launching an open-source project into a space where a lot of the development is still done Linux-kernel-style, i.e. C-language with a low-level mindset. There are multiple benefits to C++ in our space but I fear those used to working in C will be scared off. How can I make the case for the benefits of C++? Specifically, the following C++ attributes are very valuable: concept of objects and reference-counting pointers - really don't want to have to malloc(sizeof(X)) or memcpy() structs templates for specialising whole bodies of code with specific performance optimizations and for avoiding duplication of code. template metaprogramming related to the above syntactic sweetness available (e.g. operator overloading, to be used in very small doses) STL Boost libraries Many of the knee-jerk negative reactions to C++ are illfounded. Performance does not suffer: modern compilers can flatten dozens of call stack levels and avoid bloat through wide use of template specializations. Granted, when using metaprogramming and building multiple specializations of a large call tree, compile time is slower but there are ways to mitigate this. How can I sell C++?

• High-level description of how experimental C++ features are developed?

  - by Praxeolitic

  Herb Sutter in a video answers a question about the concepts proposal considered for C++11 and from his remarks it sounds like multiple groups offered prototype implementations but all of them left concerns about slow compile times. The comment surprised me because it suggests that, at least in some cases, the prototypes being developed are not just proofs of concept -- they're even expected to perform. All the work that must take has me curious. For mature languages, especially C++, how are experimental language features developed? Is it much different from developing a compiler that implements a standard? Does a developer have a sense of if it will work and perform or even if it ever could? What are the most time consuming parts and are any parts surprisingly easier than one might expect? The question is not what does the C++ standards committee do, but rather the part that comes before. When an experimental implementation for a proposal is being put together and there aren't any completely solidified rules, how is the sausage made? I'm not a professional compiler developer nor do I expect answers with step by step accounts. I'd like a high-level idea of how this would be done or if there are any general patterns at all. I don't know what to expect from the answers but even if there are no rules to the process and the small number of people who do this just cowboy it and then, for stuff that worked out, write up the "official version" as a proposal, that answer would still be informative.

• SEO Blog Indexing : Dot Wordpress Versus a Registered Domain?

  - by rumspringa00

  I've used Wordpress for a few of my client's sites, mostly small businesses and ecommerce sites. I have found through Google Analytics as well as the All in One Webmaster plugin that when it comes to social media, using Wordpress is a surefire way of getting your site indexed by Google and occasionally Bing and Yahoo. Since I am a heavy WP user, I'd like to contribute by registering a dot Wordpress domain for my portfolio. When using a WP installation concurrently with a WP domain, e.g. myportfolio.wordpress.com, will the site be more or less likely to be indexed rather a generic myportfolio.com domain? I've seen mixed opinions where people seem to favor a WP domain for URL output where others say that it's a moot point, and that Google will not favor a WP domain over a dot com domain as long as your meta tags are updated and content is keyword optimized. I tend to disagree and believe a WP domian would more likely be indexed and output more URLs over an individual, laconic domain like myportfolio.com. Am I wrong? Thanks in advance!

• I can write code...but can't design well. Any suggestions?

  - by user396089

  I feel that I am good at writing code in bits and pieces, but my designs really suck. The question is how do I improve my designs (in order to become a better designer). I think schools and colleges do a good job of teaching people as to how to become good at mathematical problem solving, but lets admit the fact that most programs taught at school are generally around 1000 - 2000 lines long, which means that it is mostly an academic exercise and no way reflects the complexity of real world software (a few hundred thousand to millions of lines of code). This is where I believe that even projects like topcoder/project euler also won't be of much help, they might sharpen your mathematical problem solving ability - but you might become a theoretician programmer; someone who is more interested in the nice, clean stuff, and someone who is utterly un-interested in the day to day mundane and hairy stuff that most application programmers deal with. So my question is how do I improve my design skills? That is the ability to design small/medium scale applications that will go into a few thousand of lines of code? How can I learn design skills that would help me build a better html editor kit, or some graphics program like gimp?

• cookie not being sent when requesting JS

  - by Mala

  I host a webservice, and provide my members with a Javascript bookmarklet, which loads a JS sript from my server. However, clients must be logged in, in order to receive the JS script. This works for almost everybody. However, some users on setups (i.e. browser/OS) that are known to work for other people have the following problem: when they request the script via the javascript bookmarklet from my server, their cookie from my server does not get included with the request, and as such they are always "not authenticated". I'm making the request in the following way: var myScript = eltCreate('script'); myScript.setAttribute('src','http://myserver.com/script'); document.body.appendChild(myScript); In a fit of confused desperation, I changed the script page to simply output "My cookie has [x] elements" where [x] is count($_COOKIE). If this extremely small subset of users requests the script via the normal method, the message reads "My cookie has 0 elements". When they access the URL directly in their browser, the message reads "My cookie has 7 elements". What on earth could be going on?!

• My proposed design is usually worse than my colleague's - how do I get better?

  - by user151193

  I have been programming for couple of years and am generally good when it comes to fixing problems and creating small-to-medium scripts, however, I'm generally not good at designing large scale programs in object oriented way. Few questions Recently, a colleague who has same number of years of experience as me and I were working on a problem. I was working on a problem longer than him, however, he came up with a better solution and in the end we're going to use his design. This really affected me. I admit his design is better, but I wanted to come up with a design as good as his. I'm even contemplating quitting the job. Not sure why but suddenly I feel under some pressure e.g. what would juniors think of me and etc? Is it normal? Or I'm thinking a little too much into this? My job involves programming in Python. I try to read source code but how do you think I can improve me design skills? Are there any good books or software that I should study? Please enlighten me. I will really appreciate your help.

• What are the signs that a ten days debugging session will not resolve an issue? [on hold]

  - by smonff

  Ten days ago, we fixed a bug on a large application and the hot fix has created a disappearing of some data from the user point of view (side effect). Data are not deleted, but have been set to hidden status. It could be possible to get the data back, but the thing seems to be hard: we've already spent 10 days to understand and reproduce the problem (mostly with SQL queries but sometimes it is necessary to update the database to test the application logic). My questions are : is 10 days a normal amount of time for these kind of problems? should we keep on and retrieve the data or should we give up this work (so the customer-relationship person will tell these users sorry for the loss, but your data have disappeared or maybe tell nothing at all)? what can be the signs that shows that we should stop to search for how to solve this issue? Edit about the context : we are a small team(3), users are not the customers, and lost data are not about the users money, bank or vital data. This is a question from a confused developer about development methodologies and business concerns, not about how we should deal with the customers.

• Building MySQL with boost on windows

  - by user13177919

  As you've probably heard already MySQL needs boost to build. However, in the good ol' MySQL tradition, the above link does give you only the instructions on how to build it on linux. And completely ignores the fact that there're other OSes too that people develop on. To fill in that gap, I've compiled a small step by step guide on how to do it on windows. Note that I always, as a principle, build out-of-source. The typical setup I have is : bzr clone lp:~mysql/mysql-server/5.7 mysql-trunkcd mysql-trunkmkdir bldcd bldcmake -DWITH_DEBUG=1 -DMYSQL_PROJECT_NAME=mysql-trunk ..devenv /build debug mysql-trunk.sln This has been tested to work on a 32 bit compile using VS2013 on a Windows7 64 bit build. Note that you'll need other things too (bison, eventually openssl etc) that I will assume you already have set up. Steps: Download Boost 1.55.0. It's the *only* version that is known to work currently. Extract boost_1_55_0/ from the zip to c:\boost\boost_1_55_0 Go to Control Panel/System/Environment variables and set WITH_BOOST=C:\boost\boost_1_55_0 in User variables. Make sure you restart your open command line terminal windows after this !  If you're upgrading from non-boost build, remove your bld/ directory and create a new one. run cmake as you'd typically do. You should get: -- Local boost dir C:/boost/boost_1_55_0 -- Local boost zip LOCAL_BOOST_ZIP-NOTFOUND -- BOOST_VERSION_NUMBER is #define BOOST_VERSION 105500 -- BOOST_INCLUDE_DIR C:/boost/boost_1_55_0 Build as normal (devenv /build debug ...).

• What's a good algorithm for a random, uneven distribution of a fixed amount of a resource?

  - by NickC

  Problem I have X, a positive integer, of some resource, R. There are N potential targets. I want to distribute all of R to the N targets in some "interesting" way. "Interesting" means: Some targets may not get any R. It should rarely be near even (with a majority of target getting near X/N of the resource). There should be at least a small chance of one target getting all of R. Bad solutions The naive approach would be to pick a random target and give one R to it and repeat X times. This would result in too even of an approach. The next idea is to pick a random number between 1 and X and give it to a random target. This results in too large of a number (at least X/2 on average) being given to one target. Question This algorithm will be used frequently and I want the distribution to be interesting and uneven so that the surprise doesn't wear off for users. Is there a good algorithm for something in between these two approaches, that fits the definition of interesting above?

• Top down or bottom up approach?

  - by george_zakharov

  this is the closest I think I can get to define my problem. I'm an interface designer and now I'm working with a team of programmers to develop a new CMS for a heavy media site. I'm sorry if it's a very, very dumb question to ask here, but I really need some help. As I've started developing a specification list for a prototype it turned out a very big one. I do realize now that the client-side will be JS heavy, with lots of DnD and other "cool designer stuff". The CMS will even include a small project management system for its users, nothing big like Basecamp, but with a live feed of comments etc. The problem is the the team has now separated. Someone is proposing the existing backend solution used in other CMS, someone is proposing to rewrite everything from scratch. The point to keep the code is that it is faster, the point to rewrite is to make it better for the proposed design (include Node.js and other stuff I don't actually get). The question is — can the UI specs influence back-end? The guys that propose to use the existing solution did everything with the Yii framework (as far as I know), and they say that everything on server is not affected by this "interface coolness". Others say that it does, that even autosave can't work without server load. Please, if this is really incomprehensible, again, I'm sorry, and I'll happy to clarify it after your questions. Thanks in advance
