i'm building a .net app using ASP.net 3.5 on win '03 or '08 (not sure yet) using SQL Server 2008.
A major part of the app is building a powerful search function which has to cluster search results similar to this site.
e.g. search for blindness and you see a cluster of results for blindness but also for visually impaired, eye etc.
I'm looking for recommendations for approaches working with off the shelf indexing technology on windows server 2003/2008 (preferably open source).
I've looked at:
Carrot2 - http://search.carrot2.org/stable/search
which looks very powerful but seems to rely on other indexes like Lucene and Solr.
Has anyone any experience working with these technologies on a windows platform? Do they play nicely with IIS?
Many thanks for any assistance.
Ed
There is a c# port of lucene (called lucene.NET) which works perfectly on windows (as you would expect, since it's using .NET).

I hope this question isn't too obtuse; however, I couldn't find anything specific. I'm a web-developer and I have an MSDN Subscription that gives me access to any SQL server edition I want. As a developer, I would like to know what I should choose to install on a dev machine based on this criteria (which other developers may relate to):
I need access to all the tools for SQL and T-SQL programming (I think all editions come with this?)
I want it to be efficient--I don't want it to take up too much ram\cpu processing time. My queries will not be very heavy so I'd rather trade off longer queries than to have the server taking up valuable resources.
I am programming for an enterprise sql version hosted somwhere else, but I don't need more than 1 Gigs of space, 1 CPU core support,
I never really worked with reporting tools, but would as a developer (Aka, non-DBA) would I ever need them on a dev machine?
Best integration with VS2013
I know that the SQL Server Developer edition is basically Enterprise, but without the liscence to use it for non-dev purposes. Based on the above criteria is there any sense for me to install it? Or should I choose SQL Express with Advanced Services? Perhaps Web?
Thanks for all your help,
All editions come with all the tools (unless you get into the BI side of things, then I think Express won't come with all of those tools).
In general, the edition won't make your local development environment any different in terms of resource usage. There are a few things that Enterprise / Developer have (like online index rebuild, certain optimizations etc.) that can make some operations more efficient, but these are highly unlikely to impact your day-to-day work or really change the number of resources SQL Server uses (these are very easy to cap through configuration anyway, e.g. if you don't want SQL Server to use more than x GB of memory, you can set that).
If you don't need more than 1 GB / 1 CPU in the ultimate deployment, you should probably develop on Express. This will prevent you from using Enterprise features inadvertently (which can happen if you use Developer). The down-side is that if you later do need features that aren't in Express (say you have another project where you will be deploying to Enterprise), you'll need to add an instance (with or without removing the old one). Given that you have access to MSDN, maybe the best solution is to install two instances - one Express, and one Developer, and then you can target the edition you want by using the appropriate instance locally.
I think that Express with Advanced Services come with these things, but I'm not an SSRS guy, so I'm not sure.
No single aspect of integration with Visual Studio should be edition-dependent.
Also, Web is not an edition that is suitable for your workstation - try to find a license somewhere. This edition is exclusively for web hosts and resellers who offer SQL Server as part of their hosted offerings.
I need to set up a web server on WinCE (7.0) and the following are some of the features that I need to implement through this web site:
be able to update the device software (run an exe) and display output
start/end process
display the run-time of device
Should I use ASP or ISAPI on my web server on WinCE 7(WEC 7) platform? If you include some reasons for your response, it would be great.
I was planning on using ASP because of its simplicity compared to ISAPI; however, when I tested a simple Hello World(hello.asp) page on the device, it took around 30 seconds to load the page. For testing purposes, I am using Windows Virtual PC. So I am not sure what is causing it to be so slow. If you could please enlighten me on this topic too, it would be great.
I looked up ASP .NET Compact framework but I am concerned about performance again.
I am beginner on WinCE development and web development so any answers would be greatly appreciated.
If you need any other information to better answer the question, please let me know and I will provide it.
Classic ASP on CE is really, really limited. You're not going to be able to hit your targets without a custom COM control, which is not very fun to write or debug and it will have to be installed on the service device. Out of the two you've proposed, ISAPI is the only one that will reasonably do what you want.
It's a side note, but from experience I'd not use either due to the absolute pain of debugging either one. I'd use a separate commercial ASP.NET web server for Windows CE. Of course I created it, so I'm biased, but really, even creating your own port 80 server is going to be less painful than the piss-poor out-of-box offerings in CE.
I found out the problem with the slow loading ASP. It is an error with the WinCE 7 web server. Microsoft has released an update that fixes that problem.
Windows Embedded Compact 7 Monthly Update July 2011
So I think I will go ahead and use ASP. I'll see if I can add the features that I need to implement.
I just wonder what are the similar frameworks and tools for Linux web development.
And can I use Visual Studio to develop websites for Linux Apache? Thanks.
Mono (it supports ASP.NET) and MonoDevelop, I guess.
Web development on Linux isn't specifically tied to one programming language, framework or IDE. More commonly they are related in terms of being Free and Open Source (free as in cost, and also the ability to do what you want with the code).
I loved Visual Studio when we used it for classes, however I haven't quite found a tool that is the same. The only thing near to this would be Eclipse or Netbeans.
In general, many Linux enthusiasts use emacs or vi (or vim) for their editing. At first glance you may not see the power they have, but emacs is definitely a wonderful editor, and vi is very good once you become familiar with it.
For Web programming langauges and frameworks, you have a variety to pick from.
Python is one of the most popular languages to use for Web development. This language has been used by Google, Reddit, Quora and a host of others. Perhaps the most popular framework for Python is Django, and each (Python and Django) have their own following, as well.
Ruby is a wonderfully beautiful langauge, too. Most likely you may have heard of Ruby on Rails, which is a great Web framework allowing you to quickly turn an idea into something actual in no time.
PHP is another popular language, and has the PEAR framework. Many of the online forums that you can buy are written in this language, such as vBulletin and the ever famous phpbb.
In my opinion, it depends on what you want to accomplish. Python and Ruby are great for Web development, as well as non-Web, too.
Ad 1) There are several IDEs. I prefer eclipse, no matter if for html, php, python, c or java.
Ad 2) Yes you can. Create your websites, copy them to your /var/www (or wherever your ww-root) is and you are set.
EDIT: < personal opinion > By the way, I mean there is no thing like "windows web development" and "linux web development". In the end it is of no importance at all on which OS you developped your web application, on which OS the web server runs, which OS the client has or which server- and client-side languages you used (as long as you don't use something certain clients can't provide). You have a web server that communicates via HTTP, HTTPS (or whatever) with clients. This server passes certain data via CGI, lib-apache2-mod-XYZ, WSGI, the interface IIS uses for ASP (or whatever) to executable scripts. These yield a result that the web server then publishes via (fill in arbitrary OSI layer 7 protocol) to the client, no matter what the content: HTML, CSS, images, JSON, you name it. Your operating systems has nothing to do with this.
Not all interfaces are available on all hosting server OS, but you always have a bunch to choose from and what counts is the result in the end. Quidquid agis, prudenter agas et respice finem. < /personal opinion >
There are a ton. You can use mono for ASP.NET that runs on Apache. There are even other languages. PHP, JSP, Djanjo, Ruby on Rails, Node... just to name a few languages/frameworks. There isn't a build of Visual Studio for Linux and you would be hard pressed to set it up to compile Linux assemblies on Windows.
I would like to do some japanese text to speech on my dedicated windows 2003 x64 server with .net framework, using c#
I found something on google, but requires to install a lot of files on the server... i don't like, for stability issues: there is another option, like a linked dll or something?
You can use Microsoft Speech SDK. It's a set of COM APIs containing TTS and SR engines. I'm not sure if it contains Japanese TTS though.
What you most likely want is the Microsoft Speech Server especially if your webite is going to encounter any decent load or volume.
From the site:
"A speech platform, MSS contains all
the server components for deploying
telephony (voice-only) and multimodal
(voice/visual) applications. MSS
combines Web technologies,
speech-processing services, and
telephony capabilities into a single
system. "
There is also a dedicated Microsft Speech community which will likely help you get started in this realm. Also, I'm not sure what the latest version is...2004 R2?
This article has a decent diagram outlining the various components. Looks like a good fit for integration with an ASP Web Application.
using SAPI in an ASP.NET website, is impossible: the sound will be reproduced on the server :S
It seems that there is the need of Microsoft Speech Server
...
Or not? With asp.net is possible to run a commandline exe on the server to save an mp3, then stream that mp3, right? (how to do that? i will try to figure it)
I will go this way, i let you know the result :)
edit: this is how i solved:
How to save text-to-speech as a wav with Microsoft SAPI?
I save the generated voice in a wav file, then i embed it on the page, playing it in a flash player
COOL!!
Use Microsoft Speech Library and see this article Text to Speech with the Microsoft Speech Library and SDK version 5.1 in CodeProject. Also see Giving Computers a Voice in Coding4Fun
The System.Speech.Synthesis namespace has been part of the framework since .NET 3.0. However, it has internal dependencies on the Speech SDK COM libraries (it chooses the correct version depending on the host OS), so I would recommend prototyping the work before you jump in.
The class you should probably look at first is System.Speech.Synthesis.SpeechSynthesizer (whitepaper and example code)
Warning: I have personally experienced issues using the speech APIs in an ASP.NET environment whereby the request that returned the audio data never returned. Despite heavy debugging I was never able to resolve the issue and the feature was dropped. I have had an unresolved support case with Microsoft for 12 months now.
I'm currently using a linux server, we run a couple of web sites of it, PHP apps with MySQL, the usual. Since the server is privately owned by some friends and myself (we do have it hosted at a professional datacenter though), from time to time we also use it to host our smallish counter-strike source and call of duty 4 matches by running the released dedicated game server packages.
I've recently subscribed to DevExpress' excellent WinForms and ASP.Net component suite, and is contemplating moving to Windows to make use of those ASP.Net components. I'm currently trying to decide between the Web and Standard editions of Windows Server, since there is a difference of nearly a thousand bucks (where I come from)
For Windows Web Server 2008, Microsoft has softened the database server restrictions and made it clear there is no need for CALs. But would one be able to run the above mentioned web servers? I've been googling and searching through forums to no avail.
Need some help before I plunk in the cash.
Thanks.
Before I give any opinion, I'll start by answering your core questions:
Yes, you can run dedicated game servers on Windows Server Web ed.
The differences between web and standard:
Web only supports 2 gigs of ram. Standard in 64bit mode can support 32gigs (and more?).
Standard comes with more things that are better suited to local server environments (eg: active directory). If you want LDAP controlled Exchange email, you'll need Standard. Most web server don't need these.
Web (apparently) won't support full-on SQL server versions. Express should run though.
Opinion time.
Dedicated and virtual dedicated monetary overheads on Windows servers are a lot... To the degree where you're paying more for the software than the hardware costs, at least for the first year.
Renting the software (as part of a managed dedicated server or VPS) is initially a lot cheaper, but over the course of a couple of years, will cost you about the same and if you run it longer, it'll eventually cost you more.
Shared Windows hosts can be good. I've been with a company called Hostek (Florida-based) and they've bent over backwards to make hosting a fairly busy site (around 6000 uniques a day) very cheap for me. It can also be atrocious. I've had bad hosting companies too. Shop around.
About a year ago, I dropped Windows at home in favour of Linux. I'm not going to enumerate the many benefits and drawbacks; I'll just tell you that that's when I stopped doing .NET in favour of more open Frameworks. I'm not using Django (a Python-based web framework). While you might not like it (or other frameworks - eg Ruby on Rails), I plead that you do check out what's happening in the open-source world before you plonk for anything Windows related since you already have the infrastructure available for hosting Django/Rails/et al.
If you wanted your own Linux server, VPSs start from around $20pcm. As I said before, severely cheaper than Windows counterparts. I now use Linode to host everything new I make. Highly affordable and they'll easily run dedicated games like your current set-up does.
Mono isn't an option for you. Not yet anyway. It does go some length to help people migrate their applications but it's still pretty sketchy on the ASPNET front. And as a comment says on another answer: the controls you want to use are strictly Windows-only for the moment.
Linux will consume fewer baseline resources than Windows will. On an old server (Windows 2000, IIRC) I had to administer, the core of Windows would consume anywhere from 100-200 megs of RAM. My current Ubuntu server eats 40megs. I'm not sure how much RAM you have to play with on your server but if it's a lower amount, you're going to fit a lot more on a Linux host. (Remember that if you have more than 2gigs, you don't have the choice of the Web Server edition)
It's clear from this that I'm a complete Linux super-enthusiast, but I know my needs differ from yours. ASP.NET is a great platform but it costs a lot of money even if you're splitting it between friends. You could opt for Windows... Or you could go Linux, donate a bit to the projects you use and buy a new plasma or something shiny for the lady.
SPLA? Isn't that for service providers? My friends and I use the hosted services for ourselves (games, email and web), though of course our web sites are publicly viewable by all; but I think that hardly qualifies as "providing a service"?
Unfortunately, staying with Linux would make it such that I would not be able to use my DevExpress components, which is my reason for considering Windows Server in the first place. .NET may be partially supported by Mono, but not fully, and DevExpress makes use of certain features of .NET that aren't (at least as yet) supported by Mono.
We also already own our own dedicated server, so are only looking for a suitable OS.
Still, your reply is appreciated.
