I maintain 2 identities one for open source development - which doesn't really contain any personal information. I also have another identity obviously - my real one.
This may be community wiki - but my question is programming related in that when you put software out there, you publish it with some name as the author, and that choice may have real life consequences.
I am considering merging my identities, what are the pro's and con's of this? Is it a good idea, or do privacy concerns outweigh the convenience of maintaining a single identity.
(By the way, this second identity was created out of my World of Warcraft addon development, and I have just continued using it for my open source projects)
Edit: I am considering this, because I am thinking of changing jobs, and I want to refer to my open source work without it looking unprofessional due to the author naming.
Well, as a part-time open-source hacker, I've recently discovered that ohloh can help you "professionnalize" your identity by allowing you to reclaim all the commits you've done in projects knwon by this engine (and they're numerous).
As a consquence, instead of merging your identities, I would suggest you give them some weight by marketting the contributions you've done.
Besides, I've never considered as valid the fact that commiting for a game plugin as open-èsource activity was not that professionnal. It is code, and code used by non-developpers, which must be noted.
In many professions using a pseudonym for publishing works has a long tradition until today: Artists, writers, etc.
Is it really unprofessional for a software developer to do the same?
If you are good, why not get a little famous? Who knows, if person hiring you is not using/participating in open source project and you'll be valued more from the start?

I'm using VS2010 and TFS to build a complex medium sized website.
Which protocol is most efficient and secure? I think I can enable any protocol I need since I own the IIS server and control all aspects of it.
My choices are:
Webdeploy
FTP
FileSystem

There is also a hint at something called "one click"... not sure what that is, or if it relates to any of the above.
OK.. I'm sorry, but I'm not sure where to even start, and I'm not sure the question is answerable as-is. I'd probably put this as a note if there weren't a limit on the number of characters.
So much depends on the type of data in this app, your financial resources, etc. This is one of those subjects that seems like a simple question, but the more you learn, the more you realize you don't know. What you're talking about it Release management, which is just one piece of the puzzle in an overall Application Life-cycle Management strategy.
(hint, start at the link posted, and be prepared to spend months learning).
Some of the factors you may need to be aware of are regulatory factors that you many not even have thought of. Certain data is protected, and different standards require you to have formalized risk and release management built into your processes. For example, credits card data, medical records, etc, all have different regulations (some actual laws, some imposed by the Payment Card Industry) that you need to be aware of.
If your site contains ANY sensitive data, you need to first find out whether any of these rules apply to you, and if so, which ones? Do any of them require audit trails for how code goes from development to deployment? (PCI does, for example. That's because we take credit card payments, and in order to do that, you need to be PCI Certified or face heavy fines.)
If your site contains NO sensitive information at all, then your question could be answered as-is, and the question becomes a matter of what you're comfortable with.
If your application DOES contain sensitive info that makes it subject to rules that mandate a documented, secure ALM process, then the question becomes more complex, because doing deployments manually in such a situation is a PAIN IN THE BUTT. It' doesn't take too long before you start looking at tools to help automate some of the processes. (Build servers, tools such as Aldon for deployment, etc. There is a whole host of commercial and open source software to choose from.)
(we're using Atlassian for most of our ALM, but Team Foundation Server is also excellent, and there are a TON of other options.)
A friend wants to start a dating website, she wants me to help her. We still haven't discussed on what platform it'll be developed, but I'm thinking she'll suggest LAMP to save a buck (which is one reason already to chose over ASP.NET already). If the dating website does well, it'll potentially hold a large amount of data (I'm not sure if this would be another reason to consider either ASP.NET or LAMP).
Anyway, I ask this from an ASP.NET developer point of view. I have very little, almost null experience with LAMP, and I don't like it very much either, so if she decides to go with PHP odds are I won't help her. So what would be some good points to bring up when deciding which platform to develop on?
Please be objective, I don't want this to be argumentative or anything, try to stick to facts, not opinions alone.
Thanks!
What generally matter in that kind of choice is :
How much time will it require ?
How much money will it cost
Which is often linked to the time ^^
If you have a lot of experience with .NET and none with Linux/Apache/PHP/MySQL, choosing LAMP will mean that you'll need much more time : a whole lot of new stuff to learn.
It'll also mean that your code will probably not be as good as it would be with what you know.
After, the question is : do a couple of week "cost" more than a few licences ?
Only you and her can decide, there ;-)
If LAMP makes you queasy, you can try ASP.NET over Mono.
IMO the only good reason to move away from a programming environment that you are already experienced with is the one you already mentioned: cost.
You would use LAMP specifically to build appliances. If you're not building appliances, the software cost for ONE server is marginal, and is not worth the tradeoff for moving to a totally different development environment, IMO.
I think the first question is: Which is the target programming language and environment that you have experience with?
Imagine the site will become a success - how do you scale then? LAMP can scale, and so can WISC, but in both scenarios you need people who actually know the environment and who can secure it. If you don't know Linux and MySQL and PHP, how are you going to scale and secure it?
So even though LAMP may be significantly cheaper (The SQL Server license is the heavy part in the WISC stack), after the first hacker attack or downtime, that initial savings may seem marginal compared to the damage.
The other thing is of course the PHP vs. ASP.net/C# decision. If you don't know PHP, then it's a decision of "Not having the application at all" and "Having the application on an expensive stack", unless your partner of course decides to hire someone else to develop that.
Technically, both have their pros and cons, but there are huge websites built on both stacks, so it really boils down to "Which platform can you reliably/comfortably setup and maintain?"
I agree with Pascal. Go with what you feel comfortable with in completing the project and don't forget that YOUR TIME EQUALS MONEY. You have to put a $$ value on your time. LAMP may be cheaper up front but if it winds up taking 1000 extra manhours, then suddenly it's more expensive.
Also take into account the lost opportunity cost in not being able to bring something to market b/c you chose a technology you were not familiar with.
At the end, if the plans are for this to be a business that is successful, the cost of using ASP.NET should be negligible or else I would question the seriousness of the effort.
One argument for the Apache/MySQL/PHP stack is that it's available on most major platforms (Windows/Linux/Mac/BSD/...) and most webhosters provide it as well.
You also find many (as in "huge amounts") of good tutorials, books and other educational stuff about PHP/MySQL.
Apart from that all tools used in the LAMP stack are free (as in "free speech" and also as in "free beer"). ASP.NET is still a proprietary technology owned by Microsoft. I'm not a huge open source fan, but knowing that your tools will remain free to use in any way you want is quite nice.
Of course, if you have no experience with PHP at all and much exp. with ASP.NET it's easier for you to stick with ASP.
If your comfortable with Microsoft products there's nothing to stop you from developing code in .NET and using a free database (however you may need to find/develop a custom database adapter if you are not using free versions of SQL server or Oracle). If you are generating a lot of traffic you can swap out the data layer of your code and invest in a better performing database.
Time costs money and if you can develop a better product both from a user and maintenance/performance perspective it will serve you better in the long run.
Some hosting companies include the OS and flexible contracts so I would make fit from your prespective. The market's pretty competitve for that type of site and there's no point throwing a lot of money at it until you get some useful metrics for your site IMO.
The short answer is: it doesn't matter, unless the site is going to do something so amazingly different that one technology is obviously better suited. And I can't think of anything like that off the top of my head.
A big red flag is: if your friend is concerned about the extra $5/month for asp.net hosting instead of LAMP hosting, then you're probably not going to get paid. Ever.
Caveats aside, be realistic: what is the immediate goal? To get something working, or to design something on the scale of plentyoffish.com or facebook.com? [Facebook.com has about 44,000 servers at the moment]
So, what are the chances of your friend's dating web site exploding to the size where scaling is a concern? For most sites, the answer is "very close to zero" - because of the marketing effort required to drive that much traffic.
Now, what is the revenue stream? Is there any expectation that you will get paid to do this? Do you think the site will be profitable? Is the project fully funded?
Friendship is great, but don't let that keep you from asking the appropriate business and client-relationship questions. One sure way to ruin a friendship is to do some work for free and/or without thinking through the full extent of the project. Far too often, you think it is a one-time favor, while they think it is your job!
LAMP is only cheaper until you read the fine print. It's not better or worse technically, just different.
The WebsiteSpark/BizSpark programs will get you all the Microsoft software you need to get started, free for three years. If price is her driving concern, point her to those programs if she's willing to consider the ASP.NET platform.
Hosting will cost a fair amount either way, because for a full-service website you don't want to go shared. You'll need at least one dedicated server to support a dating site. The OS and database will be free either way if you go with one of the *Spark programs I mentioned.
As a small startup company you can get a free 3-year MSDN subscription (well, you have to pay $100 at the end of the 3 years). If you think .Net will be more efficient and this website will make money, seriously consider BizSpark.
Since you are looking for dating site, check out Markus Frind of plentyoffish.com he is running the largest dating site on .net platform with asp.net and sql.
My company has a control panel website written in ASP.NET. We run an online service used by over 20,000 users worldwide, mostly from the US, Japan and several European countries. It is used mostly by business users.
We face many problems using ASP.NET and development times are lengthy. I played around a bit with Flex and I can see why it would cut down development times however I am afraid we would not be able to support browsers that do not have flash installed. Considering the fact that many of our customers are business users in companies that might not allow to install flash.
Your opinion and suggestions will be appreciated.
This isn't really a programming question, it is a commercial question for your product management and marketing people. Flex requires Flash as you are aware, so the answer is to find out the degree to which Flash is supported in your customer base - and the version. Start with your biggest and highest profile customer. If you can't get away with it there it is a non-starter.
I am pretty sure that your feature set will be better as well as your development time if you use Flash/Flex for your control panel, so from that standpoint I would strongly advocate it. You may also be able to influence your customers' environments if you are adding highly valuable features, so the objection may disappear if the value is high enough.
However the value has to be quite high for people to contemplate such a change to their working environment. This is especially true in environments who feel that Flash is a risk and have removed it because they tend to be paranoid about software on the desktop. Shorter development times is not a good argument for anyone on the commercial side of the house when faced with such trade-offs, so beware of forwarding that in a customer context as a compelling argument - it isn't.
HTH and good luck - I hope you manage to switch over, you will have a huge amount of flexibility and sizzle added to your apps.
In your current ASP control panel you should put in a small flash script to see how many users can access it, if all or most users can access it then then it shouldn't be a problem to use flex. Over all most users have flash and it shouldn't be a problem.
I work in a shop that is mostly .NET based, and we're trying to pick out a content management system to use. This means we mostly likely won't be able to use any of the common open source CMS projects (Plone, phpNuke, anthing not based on .NET, etc.).
Since I'm a huge usability nerd (just finished reading The Design of Everyday Things by Norman), I've been looking at them from that point of view. Frankly, I haven't been too impressed. This quote sums it up:
Most open source content management software is useless. The only thing worse is every commercial CMS I’ve used. - Jeffrey Veen
Here's a short list of our requirements:
Has to be .NET based
Prefer open source or on the inexpensive side
Limited feature set (we don't need too many features and they make things harder to use)
Does need Active Directory integration and robust permissions
Should be focused on web standards and usability
I know it's probably an impossible feature list, but are there any content management systems that kinda sorta look like they might not suck more than a Dyson?
Edit:
Here's the current situation:
I'm going to push for N2. I've got Active Directory integration working well (I even wrote a custom role provider). The only thing missing is workflow functionality. Hopefully I can get something going with that since it's the last sticking point. The N2Contrib project might provide a starting point if I can figure it out.
I would still love to check out Stencil CMS if/when it gets off the ground.
One of my co-workers was trying to get Umbraco going but wasn't having much luck.
Thanks for the help!
Self-plug is lame, but what you're describing is pretty much exactly what I am getting ready to release for $79 a pop. If you're still looking in a few weeks, take a peek. If you'd like, shoot me an email (rex#stencilcms.com).
I've heard both positive and negative feedback about Umbraco. A lot of people like Graffiti, but it's more blog-oriented than a full-blown CMS.
Check out N2 (http://n2cms.com/). I think that it covers most, if not all, of your requirements (I don't think it has Active Directory capability at this time). We are using N2 and I have really enjoyed how flexible it has been.
My company just completed a review of several commercial .NET-based CMS/portal platforms and, while I can't reveal who was in them (thanks, NDAs!), I can tell you that IMO they all sucked very, very badly.
Good luck on your search. I'll keep an eye on this thread in the hopes that there's something we missed.
We had a similar set of requirements and chose Telerik Sitefinity. It's got it's faults but overall I've been happy with it so far.
Unfortunately Jeffery speaks the truth. Which is probably why I build a new custom cms from the ground up every few years. Basically, the motivation for "boxed" CMS packages is to have every feature on earth and be everything to everyone and therefore do nothing particularly well for anyone. With the feature bloat comes the usability nightmares. Unless you start customizing and then you usually end up forking the project and losing the advantage of community updates.
Kentico CMS according your list:
Has to be .NET based
It's .net based, .NET Framework 2.0 or later
Prefer open source or on the inexpensive side
Free edition which can be used for commercial purposes is available, paid license starts at $750, source code is an option
Limited feature set (we don't need too many features and they make things harder to use)
Many built-in modules/features, anyway they can be easily disabled to keep the UI simple to use
Does need Active Directory integration and robust permissions
AD, Forms and Live Id! Integration
Should be focused on web standards and usability
UTF-8 Support including RTL languages, WAI Compliant, XHTML Compliant, XML, XHTML, HTML, XSLT, CSS.

I am evaluating WF for use in line of business applications on the web, and I would love to hear some recent first-hand accounts of this technology.
My main interest here is in improving the maintainability of projects and maybe in increasing developer productivity when working on complex processes that change frequently.
I really like the idea of WF, however it seems to be relatively unknown and many older comments I've come across mention that it's overwhelmingly complex once you get into it.
If it's overdesigned to the point that it's unusable (or a bad tradeoff) for a small to medium-sized project, that's something that I need to know.
Of course, it has been out since late 2006, so perhaps it has matured. If that's the case, that's another piece of information that would be very helpful!
Thanks in advance!
Windows Workflow Foundation is a very capable product but still very much in its 1st version :-(
The main reasons for use include:
Visually modeling business requirements.
Separating your business logic from the business rules and externalizing rules as XML files.
Separating your business flow from your application by externalizing your workflows as XML files.
Creating long running processes with the automatic ability to react if nothing has happened for some extended period of time. For example an invoice not being paid.
Automatic persistence of long running workflows to keep resource usage down and allow a process and/or machine to restart.
Automatic tracking of workflows helping with business requirements.
WF comes as a library/framework so most of the time you need to write the host that instantiates the WF runtime. That said, using WCF hosted in IIS is a viable solution and saves a lot of work. However the WCF/WF coupling is less than perfect and needs some serious work. See here http://msmvps.com/blogs/theproblemsolver/archive/2008/08/06/using-a-transactionscopeactivity-with-a-wcf-receiveactivity.aspx for more details. Expect quite a few changes/enhancements in the next version.
WF (and WCF) are pretty central to a lot of the new stuff coming out of Microsoft. You can expect some interesting announcements during the PDC.
BTW keeping multiple versions of a workflow running takes a bit of work but that is mostly standard .NET. I just did a series of blog posts on the subject starting here: http://msmvps.com/blogs/theproblemsolver/archive/2008/09/10/versioning-long-running-workfows.aspx
About visually modeling business requirements.
In theory, this works quite well with a separation of intent and implementation. However, in practice, you will drop quite a few extra activities on a workflow purely for technical reasons, and that sort of defeats the purpose as You have to tell a business analyst to ignore half the shapes and lines.
Related question: When to use Windows Workflow Foundation? My answer there:
You may need WF only if any of the
following is true:
You have a long-running process.
You have a process that changes frequently.
You want a visual model of the process.
For more details, see Paul Andrew's
post: What to use Windows Workflow Foundation for?
Please do not confuse or relate WF
with visual programming of any kind.
It is wrong and can lead to very bad
architecture/design decisions.
So, if you have such requirements, then WF is a good candidate. Of course it is relatively complex, but mention that the problems that is trying to solve is also complex (and sometimes very complex). IMHO, it is very complex for example to dehydrate/rehydrate objects that have event handlers attached (with events that can be triggered when the object is not in memory).
I can not judge what you mean by "small to medium-sized project", but in general I would say that if your project has at least two requirements from the above list, then you can consider WF as a solution.
We've used WF in a large-ish SharePoint application and I can say it's OK. It has lots of power and flexibility. and, as Kevin mentions, once you grok the underlying concepts of workflows, you can do pretty much anything you want with it.
On the other hand, it has some really serious issues, like lack of versioning, which can really hurt your application in the future. We've been forced to deploy up to 3 parallel versions of the same workflow named xxx-v1, xxx-v2 and xxx-v3 to keep older instances running and have new instances use the updated versions. A real pain in the ass. Oh, and there are also some really non-intuitive concepts in there (correlation tokens, wtf??)
We had a project at work that I was involved in using Workflows.
The idea (from management), was that us programmers would write the Workflow Activities along with the "engine" and framework. Then non-programmers would take care of all the rest by compiling their own Workflows into dlls which the engine would automatically load.
Management was sold on this idea of non-programmers using Workflow to help develop software, and it was pretty much a complete waste of time. The problem we were trying to solve with this project was relatively complex and we knew from the very beginning that the software would have to be modified almost constantly (its calculations were dependent on other companies and governements).
The end result was that we were unable to make the Workflow modules generic enough for anyone else to use. So the programmers were the ones who were forced to work with the Workflows, and all the Workflows did was get in our way.
I've been using Workflow 4.0 for the last few months and although mostly impressed, I've found it extremely hard to learn.
For the most recent version (that comes with .NET 4.0 RC), there is next-to-no documentation on the web, in any books or no training courses available. I've only found articles relating to the now defunct 3.0 version. Even the MSDN documenation is light on the ground.
The workflow designer is not as intuitive as it should be by any means so learning is very hard. I've had to rely on answers from a single person on StackOverflow (thanks by the way Maurice!) - and I would be stuffed without his help.
So in summary, I think it has potential but you would be quite mad to learn it yet - wait for more training, documentation and books otherwise you will be going into it blind!
Last year we completed a working application with WF, now used as the backbone of an unbelievably huge system which is used by a very big bank for its mortgage process. The pe process has many steps starting from customer application to approval of credit.
Although it was a success, there were so many problems and crisis all along the way. And it wont worth the trouble for any smaller size projects.
I consider MS WF as a low-level workflow library rather than a fully fledged enterprise workflow product such as K2. It will enable you to build a workflow enabled application, but is not in itself a workflow application. My experiance of it in this capacity has been positive, although we have had to build a lot of our own infrastructure around it (a pub/sub framework, a worlkflow lifetime manager etc). A lot of the documentation out there is fairly simplistic and does not cover building up an enterprise workflow application based on MS WF.
Hard to learn. Quite flexible. Not to be confused with a visual tool for end users, only for programmers. Not sure if I like the dependancy property approach.
It really depends on what you want to do with it. I've only used it a little, but compared to more mature products like MetaStorm (I know technically it's a BPM, but there is still a workflow component), Process Choriographer and IBM MQ workflow, there's no comparison. It's just not mature enough. On the other hand it's free where the others are not and can probably get the job done. I don't know if I would place a multi-million dollar operation on it, but with smaller ones, I'd give it another shot. The real hurdle you are going to face is the change in thought process it requires. If you don't have developers that have worked with state systems before that can be a real hurdle.
Brian, I can't reply to your comment, but anyway, by versioning i mean making changes to the underlying code of the workflow without breaking already running instances, and gracefully applying updates to existing workflows. I'm not sure about 'stock' WF, but at least in SharePoint environment there's no concept of workflow versions so new versions have to be deployed as completely different workflows which becomes a maintenance nightmare.
This has nothing to do with 'rehydration', rehydration is the process by which you bring a 'dormant' workflow back to activity after some event or change in state. That is handled transparently by the workflow runtime.
WF ist integrated into SharePoint (WSS 3.0), and i have created quite a few workflows for various SharePoint-Websites, so i can tell about my experience of WF in SharePoint. Compared with other workflow-frameworks WF scores well. It's stable (i haven't experienced any mysterious errors), workflows are fairly easy to design (thank to the workflow-designer in Visual Studio) and you can use not only sequential but also state-machine workflows.
It's not perfect, of course, and a developer will definitly need some time to understand the concept (of i.e. the Activity Model); but it's definitely useable - even for "small tasks".
Never tried WFF, but I remember reading this article about WFF by Leon Bambrick where he basically says the whole genre of software development tools is nonsense. Might help you decide one way or the other.
