I'm beginner in qt. I think it's useful but there is some thing wrong. I think it's not the number one developer's choice. Why developers don't like using Qt?
And what is the best replacement for Qt?
When you use Qt you get spoiled by the extensive documentation so when you switch to another toolkit you'll be miserable.
This is my only complaint with the Qt.
If you are developing purely on Windows then C# may give you easier links into Windows technologies, it's also a simpler language than C++ - although they are working on that.
For C++ there isn't really a good alternative toolkit.
On Windows, MFC is a bit long in the tooth, managed c++ (or whatever it's called this week) together with .Net is a pain^2.
On Linux, Gnome requires you to write c in c++ while thinking in objective c.
depends on language but most developers that i know use visual studio, especially for c++ etc

Recently I started looking at functional languages to make some algorithmic parts of my application more reliable. Of course I bumped into Haskell. But it prepared too many surprises for me with its laziness. Sometimes simple things become very and very slow.
So I'm wondering is there a language I can use to write small algorithms in functional style but without unnecessary laziness which causes more problems then helps.
The program should be compiled into Win32/64 native code (preferably dll) and have comparable performance with C++.
OCaml is probably the closest to Haskell, but it's strict and impure. It's a successor to ML.
OCaml, ML, and Haskell can all be compiled to machine code on any common platform.
In my experience, though, laziness is usually a great feature once you get a sense for how it works.

I googled a lot but could not get a suitable tool.
I have a .NET application. To make the reporting feature much better, I am trying to find a third party tool for reporting as well as capable to generate the reports as pdf, jpg etc.
The main thing is to design the reports by the end-user as per their needs. I checked Cognos, I found that it gives the output as grid like style but I need in a customized manner too.
I got the below third party tools.
Fast Reports
Jreport
Cognos
Combit
I need a tool, that is very easy from end-user's prospect.
Any suggestion will be helpful.
If you want end users to design their own reports on demand, have you tried the new Power View (SQL Serves 2012)?

Is anyone knowledgeable on programming language implementation of algorithmic trading?
I am going to propose a research project on functional programming and algorithmic trading.
My proposal is here: http://pastebin.com/wcigd5tk
Any comments would be very appreciated.
What do you think the future of functional languages in the financial field is? I see many job postings that ask for experience in java and C++, and i dont understand why.
Jane Street is very well known for using OCaml for their trading software. Here you can find some reasons why they decided to use functional languages rather than imperative ones. They also have a blog describing several specific solutions to problems they encountered during development.
C++ is the most popular in that field.
java , python ,haskall ,c# are all runners up
haskall and c# are functional with haskell being purely functional
eventually the field will move to a more "modern language" like c# or haskall but right now c++ has so much support the libraries are already made and its implementation is the easiest .
For Trading application, it usually has Real time, multithread, low latency, high availability to consider too. I was working in a company developing a trading application using both(mixed) C++ and Java as it fit with the behaviour of the application.

I'm trying to grab some information from a private XML file used as DB schema, I'm thinking an XQuery command line tool could help. Would you please recommend one? Thanks. BTW, the implementations list is too long for me to pick...
here two gui versions...both open source
kernow uses saxon and has a bunch of features... (EDIT:currently the newest version of kernow is trial and not free, unless you get the older versions.)
and then theres qizx which comes with qizx studio, the gui isnt as good however it implements xquery 1.1 and xquery full text
I would recommend XQSharp. It is free for non-commercial use and has more features than the free version of Saxon (in particular it is fully schema aware, and has a much more advanced optimizer).
Disclaimer: I am a developer for XQSharp and am therefore biased.
I would recommend downloading the trial of Oxygen XML editor and using it. Its not command based though... Not too sure what you are using as a development environment but if you need a good XQuery library i would recommend the Saxon libraries which i believe comes in many flavors. I know there is a .NET library.

Did anyone here a real company using JavaFX for real life applications?
I did a shallow search about JavaFX usage, and found almost no heavy usage case.
Anyone knows companies which actually using JavaFX? I'm really afraid that JavaFX (which is being currently the only somewhat opensource RIA platform) will not survive.
Update this question gives a few example of JavaFX programs (mostly code written for contests). But I saw no commercial users there.
http://www.vancouver2010.com through the Medals or the Athletes pages using the tab called Geo View. Or you can access it via these direct links:

** FR – http://www.vancouver2010.com/fr/olympique-médailles/vue-de-geo/
Ubivent and DaliReport - I haven't tried either of them but it's marginally comforting to know they exist. Of course, Sun itself uses JavaFX (no surprise there).
Of course, I've also written my own real-world JavaFX application. It's not at the enterprise level, but nonetheless sees many users.
This press release suggestions "Canoo"
I haven't heard much about people using JavaFX, but it does look like a strong contender to WPF.
Some of the shops using JavaFX are listed at javafx.com here.
I haven't seen or heard much real, large-scale use myself.
I tried to do a simple little project with it, and it initially seemed awesome, but then I hit a bunch of bugs. This was back when it was still beta though.
