Most of us who do any amount of work in web apps/web design have seen ads for PSD to XHTML conversion services. Provided with a cash outlay and a source PSD file, these services claim to return professional-quality XHTML/CSS within a few days.
Coding up the XHTML/CSS for any project is often the most time consuming portion of the project. If these services really do produce professional-quality code, then even at a cost of several hundred dollars per page, it would be financially beneficial for me to use them.
So, what's your experience with these services? Quality code? Junk? Cross-browser functionality and graceful degradation? Etc...
Thanks so much! :)
I may be a bit biased being that I come from a front end development background, but I'll say this...
The bottom line is the person who does your front end has to:
A. Be competent
B. Give a damn
C. Take the effort to go through the tedious process of making sure everything is pixel perfect, semantically correct, and engineered to work well with jQuery enhancements.
Do you think that will happen for $99? Build it yourself or rewrite it later when it becomes an issue and you have to. A good front end takes planning just like a good back end.
Choose one that makes examples of their work available. For example, this company has done good work in my limited experience with them, and makes code samples available: http://www.psd2html.com/examples.html
Based on samples of their work, you can decide for yourself whether or not their work is what you consider usable and reliable. Otherwise, it's really too subjective a question for us to answer for you.

Q:
Lately ,i asked for testing a code ,,to detect the bugs and fix the problems ,,i find many problems ,, but the main problem here is the code it self ,, spaghetti code many many code lines and the tracing to fix problems is so difficult ,, plus some code is copied and pasted from the internet as it is without any modification,, no documentation is possible to this code,,the performance is so bad due to the heavy using of viewstate in every thing,, and it takes me a lot of time to fix the problems ,, and iam afraid of after all this time still other bugs may appear in the future .. how to handle this case ,,any advices concerning this issue will be a great help.
Start refactoring. This will not make only the code better readable it will also give you a btter understanding on how it works and what it does.
That's a very common situation - software was developed for some years and by many different developers and now you have to support it. You should fight the will to throw it away and rewrite the whole application - it is a big effort and chances are big that you will do many mistakes that are already fixed in bad code. See Joel article for more explanations.
In my experience the best way is to refactor the code. However it involves writing a lot of tests - unit, automated acceptance - and it will take almost the same time as rewriting, but it will be less pain
I think the mentality for working with spaghetti code is summed up quite well in Refactoring by Martin Fowler.
The picture that comes to my mind is surgery: The entire patient except the part to be operated on is draped. The draping leaves the surgeon with only a fixed set of variables. Now, we could have long arguments over whether this abstraction of a person to a lower left quadrant abdomen leads to good health care, but at the moment of surgery, I'm kind of glad the surgeon can focus
Basically what that means is start small, and update a single part of the code at a time. Little changes will add up to good, structured code in the future.
Of course, if there are major problems with the entire architecture, you may have to heed Cybernate's advice and start from scratch (unpleasant as it may be).
I would also write unit tests as well as refactoring as codymanix said. This does a couple things:
As you refactor, you will have some check that your refactoring won't break things.
Writing the tests is a good way of learning the domain knowledge embedded in the code.
Of course, there is an inherent catch-22 with adding unit tests to spaghetti code: it is usually hard to unit test, and you need to refactor it to be able to make it testable. But if you go bit by bit and start with the low-hanging fruit, usually you can make it readable.
Scrap the existing code and start afresh.
That involves lot less effort comparitively.
If that's not a possible option start with Refactoring using tool like ReSharper that will give a good start.
I have an idea for a business that requires a well designed web application. I'm not a rocket surgeon, but I'm smart enough to know that you get what you pay for and am willing to pay for talent. However, I want the development process to go as smoothly as possible and would like to know how to make that happen.
So, what information do developers need (or want) initially from the owner to avoid having to make assumptions about business (or other) requirements? Do I need to create state transition diagrams or write use cases?
Essentially, how do I take the concept in my head and package it in a way that allows the developer to do what they do best? (assuming that is creating good software. haha)
Any advice is appreciated.

You may need to reword your question, as it is too general to get a good answer, so some vague details would be helpful.
But, the better vision you have of what you want the smoother it will be.
I find UML diagrams too confining, when you aren't going to be doing the work, as you may not come up with the best design.
So, if you start with designing out what each page should look like, as you envision it, then you can write up use cases, which are short scenarios.
So, you may write up:
A user needs to be able to log in using OpenID.
This will tell the developer one function that you want, and who you expect to do that action.
But, don't put in technologies, as you may think that a SOAP service is your best bet, but upon talking about it you may find that there is a better solution.
Use cases are good points to show what you are envisioning, and give text to your page designs.
Talk to the developers. Explain what you want and why you want it. Together you make the flow charts and whatnot. Writing requirements is part of the design process, and it's a good idea to have the developers onboard as soon as possible. Start simple and small, then grow and expand while iterating.
In talking over web services before, I have found the best starting point is drawing on a sheet of paper what you think the site will look like, and add in a few arrows from things you want clickable to the pages that should result. Keep it simple, nothing too fancy, and hopefully you and the developer can come to an understanding of what you want pretty quickly.
Use cases might be best for checking off all the points later in the project about how complete your site is; I haven't really found it to be a helpful starting point, but I'm sure others disagree. (They just seem too tedius to read when actually writing code.)
Same with state transition diagrams; they are too tedious and I think most developers will assume you made mistakes in them anyway. :) Everyone else does... Unless your project hinges very tightly on the correctness of a state machine, I wouldn't really bother.
This book contains some good advice on what constitutes a good statement of requirements from a programmers point of view. It also has the useful guideline of not trying to set the form of your requirements too early, and a substantial piece on describing the problem you are trying to solve.
I like UI mockups based on actual program/site flows e.g registering a customer or placing order. Diagrams/pictures of GUIs with structured, consistent data examples are unambiguous.
I agree that UML and use cases are only really useful if everyone speaks UML and the projects are of sufficient complexity (few are).
You may want to read up on Agile/Scrum techniques. These are becoming a sort of standard and when properly managed can save weeks of development time.
I find that words don't do a good job of communicating how a system is supposed to work. Wireframes, white-board drawings/transition diagrams, and low-fidelity prototypes are great ways to communicate a concrete idea. One example of a low-fidelity prototype is a "clickable" paper prototype that allows a user to touch "buttons" on paper to go from one drawing to another. It costs very little time (cheaper), but goes a long way to communicate an idea between two parties.
Stay away from formal documentation, UML diagrams, or class (technical documentation) diagrams that don't speak to you. This is what large, risk-averse companies move toward to be more "mature". These are also byproducts of an idea that is hashed out, and it sounds like you're in the hashing out stage.
i want to discuss about a problem: i've lately had discussions with some customers to which i've asked money for projects written in Drupal: when they know that i use a CMS they immediately say that they want to pay less "because I use a CMS".
I develope since 15 years and i've made many many projects without using a CMS and by using my libraries; i'm lately using a CMS but this does not mean that i don't write code ...
Which could be the best response to give to a similar question?
Ciao

Explain it to them very simply.
If you have to install and configure any Content Management System, that takes you more time and therefore costs a bit more than a static website. You need be as transparent as possible when you detail the costs, so tell them how much time will be spend designing the theme, how much time will be spend configuring Drupal for their website and so on.
It would be interesting to ask them why they think it should be cheaper, as you will then understand what misconception they have about CMS. You can then explain things better to them so that they understand what using a CMS actually means.
I would say that they are paying for your expertise and experience, regardless of the tools you use. If they want it cheaper, they can ask someone else. The CMS helps to add stability, security and expandability to what they would get if they had a custom solution.
Plus, if it was all custom code it would be extremely difficult to hire someone else to take over if, God forbid, you were hit by a bus. The CMS gives THEM more options.
I would agree that you should explain where the money is going, in general terms, but you shouldn't have to justify every detail. Otherwise how do you itemize "dealing with stupid customers who need their password reset for the millionth time" or "explaining the difference between a 100x100 thumbnail JPG and a 3600x2700 BMP". It could also open the door to a lot of haggling that will just waste your time and frustrate you.
I had a client who asked me over and over again the same kind of question.
If your client doesn't perceive the value you're adding to an Open Source application then give them the source code and point them to the documentation. Tell them to build it themselves.
This question is not coming from a programmer. (obviously) I currently have a programmer making a website for me and I am realizing that he isn't going to completely work out.
He has already done quite a bit of work and the site is almost there but I need someone who is better to take it the rest of way. The site has been done in asp.net and I am wondering how hard it would be for a more experienced programmer to take over and finish the work he has already done?
In general, is it hard for an asp.net programmer to come in towards the end of a project and fix what needs to be fixed?
There is five different pages on the site with two overlays for a signup and sign in. (Five pages with many different versions) There is a database and client-side scripting. AJAX was also used. It's a site somewhat similar to SO only not quite as complex and about something completly different. I would say think of something that falls somewhere between Stackoverflow and Craig's List. Thats all I can say now as I don't know the technical words.
You'll probably find that the new programmer will want to rewrite most of the code from scratch. If you are on a tight deadline or tight budget and can't accept a complete rewrite then you will need to hire someone that is not just good at writing good code, but good at reading, refactoring and improving bad code. It is two completely different skillsets and the second is much rarer. Depending on the quality of the existing code (and I'm assuming here that it is not good), your new programmer may end up rewriting much of the existing codebase just to understand what is going on.
Depends on how good the previous programmer was and on the complexity of the project. It might be anything between trivial (well commented source, some high-level docs, unit tests, modular or simple project), to "this crap needs a complete rewrite" (no docs, custom "let's try this" solutions, etc.). If you're not a developer it might be really hard to tell. And other people won't be able to answer without more details.
I'm no asp.net expert, but I suspect the ease with which the replacement will be able to finish the project will depend mostly on just how bad a job the first programmer actaully did. Bad code is painful to fix in any language. :)
A good idea will be to have them work together,for say, a week or two. This will help the new programmer get some much needed training about your current system.
You may find that although the site is almost complete, the successor will have to spend more time than anticipated when performing alterations, as this person will have the mental model of the software that the current developer has. Hence the need to next developer to "re-write" the code base.
If you can, you'll want to ensure that the code base that you have built is maintainable. That is, the solution is built in such a way that it can support alterations easily. As Mark Byers suggested, you'll want to get someone who can not only program but can also re-work your existing code with the goal being that someone else will inevitably implement future changes. If the software is something that you need to keep working for an extended period you'll want to make the investment in making sure that it new functionality can be added easily.
Remember this experience described at The Daily WTF. Take appropriate precautions.
Generally if the site is set up in some sort of standard fashion then another programmer should be able to pick it up easily. if the existing programmer did things to obscure the code then it will be hard for another programmer to pick it up. Basically the question is how readable is the code?
If the current programmer is unwilling to communicate the true status of the project in a professional, non-technical manner, then give him an ultimatum - your way or the highway. Odds are he will be more forthcoming if he knows you mean business. Make sure you have a copy of the latest code before broaching the subject.
It sounds like you are going to end up hiring someone else anyway, especially if you're asking these kinds of questions at this stage, so you might as well go for broke.
As Mark Byers said, it takes a seasoned developer to take someone else's code and resist the urge to "pretty it up" in order to bring the project to a working conclusion!
I'll do a demo of my code to slightly non-technical audience, and I need to show them what I've got in my project (about 15K lines of code). I'm trying to convince them that I've spend time on the project and it's in a good state.
These guys planning to invest money into this product. Therefore I should convince them that this app worth the price that they are going to spend and justify the time I've spent, secondly they should see that this is something takes time and I know what I'm doing (basically I need to win their trust) .
What metrics I can use other than "lines of code"? (Maybe lines of comment?)
What are the best tools (preferably free) to generate a report from .NET Projects?
UPDATE :
Also a way to provide "project cost - cocomo" would be cool, like this one :
FOUND:
http://www.cms4site.ru/utility.php?utility=cocomoii will help you to calculate an estimated cost for your project.
If they're non-technical, it won't matter. It will be like trying to sell a high-end bike to people who don't know a bike from a car. 15k lines of code won't matter to them any more than 300k lines of code will.
You need to find something other than the actual code to wow them with.
Can you code up some demos and tell them how short time it will take them to build similar applications with your code? Like "If you use my code, you can build this multimedia application in 15 minutes without writing more than a few lines of code". Non-technical people generally love saving time and money.
It probably depends on how "slightly" they are in the non-technical department.
An investor only cares about money. Investors start at the exit and work backwards. Knowing this, pitch your project in terms of the return they will get in their investment.
Key points would include:
Your expertise: Do you know the market you want to sell in to? Are you leveraging your expertise in some way to make the project a reality?
Risk: Using your already existing code base lowers risk in terms of both time and money. They will probably do technical due diligence to validate your claims, so be honest here.
Time to Market: Having a code base in place will reduce their time to market, which may be significant.
Vision: They need to know that there is a future for your product. This is your chance to get them excited!
Investment is about the future, not the past, so understand that you need to achieve what you are promising. The path you trod to get to where you are now may be interesting, but largely irrelevant to the investor. What I'm trying to say is sell the vision, not where you are now or where you've been.
Good luck and hope you get what you need!
It's not clear to me from your question whether you're talking about people who would buy the use of your product or ownership of your product.
In either case, ask yourself these questions:
"What problem(s) does this product solve for my users, from their point of view?"
"What does this product let the users do, that they already want to do, but can't do without it?"
"What does this product let the users do, that they already want to do, but can't do as easily without it?"
Features don't matter. Menus and dialogs don't matter (unless they require explanation, in which case they matter in the negative sense).
If you want numbers that interest a potential buyer of (an instance of) the product, talk in terms of how much time or money the buyer can save by using your product.
If you want numbers that interest a potential buyer of shares in your company or product, talk in terms of the size of the market, how you've analyzed that market's needs, and the ROI of any investment.
I've had success showing potential customers our automated build cycle, in slideshow form. I took them through our "production line" as if it was a factory tour, and showed the nice colored bars of coverage reports, uptilted lines of historical lines of code, pie charts of breakdowns of lines of code per module.
Then I did the same for everything aroung the actual building. So there's a requirements pipeline where they are involved, and a test/validation cycle where they are again involved.
It may not mean anything to them, but it shows them you have control over your process, and control over the quality of the delivered end product.
Please note that although people may be non-technical, try to be as honest as possible. As soon as they discover one single tiny lie in your story, you're lost. And chances are that there's that one technical guy in the back who can ask that one question which makes your house of cards fall down.
Happy sales!
"good code" doesn't matter unless you are demonstrating the medium and long term advantages of it - enhanced flexibility, simplicity, which saves customer time/money while adding agility.
I think explaining the more complex aspects of the code and the work that went into it to any audience will help show how much work and effort have gone into a project.
Hours spent coding could be a good metric to give them.
Talk about the features. Explain what you have working or almost working. Go at it from what they are interested in.
Try to show them visuals that they care about if you can. I think a few minutes doodling on a board would be better than showing lines of code.
The only thing that is likely to matter to a buyer (particularly a non-technical one)is functionality. I would concentrate on selling the features. You might consider discussion how you have tested it to verify that it performs as you claim.
I wouldn't use code per se, since a non-techie wouldn't understand it. Boasting about quantity is probably meaningless (how does a non-techie know that a 1MLOC project is significant? As for quality, you can present, e.g., maintainability metrics, test coverage, things like that. Feel free to show off your excellent toolchain too (continuous integration and all that), your mastery of various performance-testing tools. Also, showing things like Workflow Foundation helps - customers like to see how their business processes can be turned directly into code with a diagram notation.
EDIT modified to reflect OP's clarification (in comment here) that these potential buyers are looking to re-sell the software
Re-sellers are going to be looking for three things:
Is anyone going to make something better, cheaper or more quickly?
Is this guy going to be able to use our investment effectively to produce more?
Can we sell what this guy has produced, and will produce?
How to address points 1 and 2 have been very well addressed in other answers, but it's question 3 which is the hardest to prove for us techie people. It's also extremely important - if you can go to these buyers and hand them 3 killer benefits which they can repeat with more flair and Powerpoint when they're doing their sales calls, you'll be off to a good start :)
The main thing you have to do is to take a step back from your work and look at the:
features: what does it do
advantages: why is it better
benefits: why should the customer care
Features are closest to what you care about as a developer, but are pretty much irrelevant to non-technical buyers. Advantages are an essential step in understanding your competition and the customers' alternatives.
By putting features and advantages together, you can hit the customer with a number of benefits, e.g.:
using my software will save you $0.01 per transaction, or $40,000 p.a.
my software will increase customer retention by 5%
your admins will need 15% less time to deploy changes using my software
These are the things that customers care about: what's going to be good for the company, and good for them.
To be brutally honest: the end customer don't care how much effort you put into it (LoC or any other metric), they don't care how well it's written (comments, tests, any other metric), they don't care how hard a problem it is to solve, they don't care about features.
Their only requirement is that it will save them time / effort / money. You know that how hard you've worked to solve the problem, and solve it well, is key to their requirement, but it's secondary. You need to make it perfectly clear why them buying their stuff will mean they'll get promoted.
