I am writing a report at university to go along side my final project software, a SignalR chat application.
In the methodology I am a bit stuck on the system requirements. I know that there are certain system requirements for building a signalR application because I had to meet them myself, but what are the system requirements of running one?
I have written about O/S and browsers, but what else is a requirement?
Thanks
Signalr Server Requirements are basically Windows 7 or higher
and client side browser of I.E 8+, Chrome, Firefox, Safari
See here for exact specifications

I'm in the process of porting an application to ChromeOS with the requirement that it should look and feel as native as possible. This means in particular that it should allow things such as multi-monitor support and USB support.
One possibility would be to implement it as a web application (since we have already a web client), but in this case I would need to add support for native features (again, multi-monitor support and USB device access), so I wonder what needs to be done in this case. My wild guess as a ChromeOS developer newbie is that I would need to extend the code with ChromeOS JavaScript features, and I don't know if this is possible.
Another possible approach would be to write an Android application, since I see that ChromeOS added support for Android applications (in this case I would have to write the code from scratch).
Finally, another option would be to write native code, which could be possible for example relying on a Crouton development environment, and reuse the code of a native C application.
What approach would you recommend to build a ChromeOS application starting from a web application or from a native one?
What approach would guarantee access to native features (multi-monitor support and USB)?
I discovered two APIs which should help with multi-monitor support:
https://developer.chrome.com/extensions/windows
https://developer.chrome.com/apps/system_display
The system.display API allows one to discover and monitor the current monitor layout, while the windows API allows one to create several windows in the same application. By combining these ones I should be able to create a window for each monitor in case I go with the chrome implementation route.
Given that I already have a native implementation for Linux, Crostini (as opposed to Crouton) is also very appealing since it provides a deeper level of integration with virtually no changes to the code and no need to maintain two different versions of the web client, with the only downside that it requires the user to create a Linux environment and manually install the application, also it is not supported on all chromebook devices and on many it will be never supported.
I still need to check what is the performance overhead. Also the level of integration with USB I/O might be higher than the one achievable by using the chrome API.
I'd like to create a simple server service that can perform the following tasks:
Retrieve presence info for specified user(s).
Send message to specified user.
From what i've been reading, and because i'm siting server side I could choose to use UCMA 5.0? But i'm seeing a lot of push of the new UCWA SDK and working with the UCWA rest services. Is there any particular reason why i would use UCWA server side rather than just the UCMA API? I read that UCWA will, in the future, be support by Microsoft for Cloud --- Any input and experiences shared on this would be great.
Thanks, mike
UCWA will be at some point be supported in Office 365 indeed. So if you create an application with UCWA you can expect it will run in the next future on your S4B On-Prem as well as on Office 365.
I have to say anyway this support for UCWA on 365 is already long awaited, and still there's no official announcement about availability date.
A very good reason to choose UCWA instead of UCMA, also in case of server automation, is the much simpler deployment of UCWA (UCMA deployment is quite tough).
UCMA must run on a Windows Server OS which joins the S4B farm basically (thus sits in your DMZ)
UCWA can run on any device that 'speaks' HTTP. Your UCWA App can run, for instance, on a Raspberry Pi
I think this is a huge difference, for sure it is for your system administrator
Old thread, but in my experience, writing server-side code with UCMA is somewhat easier than trying to use UCWA - and all that UCWA really is is a UCMA application sitting on your Lync/S4B server with a REST wrapper.
For the fairly simple use-case you've described, you could write the service as a client-endpoint UCMA application, which avoids the rather irritating Lync/S4B topology changes and deployment headaches that Massimo alludes to for a TrustedApplication. In this configuration, you are essentially just a third-party client, and you provide the credentials to sign into Lync/S4B as a specified user. Under this scenario, the only requirements are that the server running your application needs to be joined to your domain, run a 64-bit Windows OS, and have the UCMA runtime installed.
Some sort of API support for Skype for Business on Office365 is badly needed. There was some promises of a UCMA-like SDK for Office 365, but it has been more than six months with no hints of an actual release.
I'm involved in a project with many others companies. We started to develop our systems at the same time but only at the end the communication problem was taken into account.
I've developed my system on Linux with Mono (Linux is mandatory for me). I have to communicate with a Windows .Net system which is exposing a Wcf web services. Unfortunately they told me only now they are using wsHttpBinding and I've just discovered that this communication protocol is not supported by Mono.
I'm here to ask if there is a way to communicate with that web service. They are not going to change the wsHttpBinding because is used by many other companies. I cannot change my OS and my code base is too big to leave Mono now. I can only add a layer (always on Linux) between my Mono implementation and their web services.
Any suggestions?
Microsoft has recently released the .NET source code as MIT licence (open source).
This means that, if something is not supported by Mono, you can just bring the code yourself and incorporate it, so that it becomes officially supported.
Some Mono developers have actually been doing this the past weeks to incorporate things that they had not implemented yet. So you could bring the wsHttpBinding along to Mono. An example of such a change is this commit.
I am testing one Desktop based client server application. I want to perform a Security test of that application.
Can anybody explain me which points i can consider while performing Security Test of the Desktop application?
Testing of desktop application is easier than web application as there are less users than web applications.
Followings are two important point that you need to keep in mind during security testing of desktop application
• Test user’s rights and roles-authorized person should allow to login
• Test security of data or information stored in application.
Security testing on Desktop application is not that much easy task, in market we can't find the proper free tools like web application tools
for java based desktop application use JavaSnoop tool and proxy tool
for .Net based desktop application use echo-mirage and proxy tools
the test cases are quite simple
1. System testing: verification of registries, files and logs
2. Static testing: de-compile the files and do code-review, Gendarme tool is perfect
- do memory dump analysis
3. Dynamic testing: verify the communication
i hope this will help you
What is a better platform/language for developing Windows/desktop based application that can run offline (sometimes)? .NET (C#, ASP) or Java or any other development tool? This application requires to store data into a database(involves some GIS) and later Synch both ways with the main server (SQL/Oracle) during off hours or when initiated by a user or event or when online? ALso the tool/IDE recommended should allow us in the future to migrate this desktop application as a Web based application to the corporate server with less pain or re-work when internet/nw access is available to all of our remote sites/users. Any input/advice is appreciated.
If you are strictly doing Windows desktop application development, C# or VB.NET would be an excellent choice. There is a ton of documentation out there for .NET developers. Although the framework is a free download from Microsoft, any serious work is cumbersome and tedious without the IDE.
If you needed the potential to support your application on multiple operating systems besides Microsoft Windows, then I think it might be worth looking into Java.
For web solutions, in .NET you have ASP.NET, Java you have JSP and Tomcat.
You could try Adobe AIR. It seems like it would serve most of your desktop needs and it should be the easiest to migrate into a web app (Flex).
C#/WPF for desktop with Silverlight, XBAP or even ASP as the online options.
Since you mentioned the desire to web-enable this application at some point I'd look into Silverlight. Out-of-browser capabilities were introduced in Silverlight 3. That means that the app can run directly on the desktop, and the internet connection is optional. However, when the internet connection is available it has built-in support for auto-updating itself.
And now in Silverlight 4 it's possible to run an out-of-browser Silverlight app with elevated trust. Silverlight 4 also finally introduced things like right-click support, clipboard access, full keyboard support in fullscreen mode, etc. So if you're just now starting development, I'd most definitely use version 4.
You'll have to communicate with something like a WCF service for a lot of the database operations. But going with Silverlight should allow you to build something that'll work on the desktop and the web alike without having to manage two systems.
Going web-based after you already developed a desktop application is a really bad idea. There is no reason the desktop application cannot use a internet connection, and be updated from a server.
You could try Delphi. It's a rapid application development tool. Very different, but very quick to use. Well suited to Oracle integration. Data sync is probably going to need to be custom, unless you're using something like Sybase SQL Anywhere.
