I don´t know if this is the best place to ask this question.
But I need to find a solution to a problem I have.
I need to provide access to personal virtual desktops to a few users.
And I need to see what options I have for this.
I can provide some machines to work as servers if needed. And I can pay if there is some type of option using the cloud or other service.
I just need to be able to provide a few user the access to a desktop with security and with long lag and latency . So they can work and use application in the remote server.
I will be thankfull for all the help and solutions
Did you try with https://deskroll.com/ ?
I use it bc it doesnt require installation, works easy in the browser and has free trial and very cheap license.

I don't know if my app will work in China and I don't know how to test it. I had read somewhere that there's a firebase Chinese domain .cn in operation. Is there a possibility to transfer the current project to the Chinese domain and make it work, if it doesn't already?
If I create a new project and select the Chinese servers for my firebase services then will it have any other adverse consequences for the rest of the world? This solution would literally force all the developers to have the firebase servers located in China, just so they don't miss out out on their Chinese user base, which I assume could be an issue to some.
I might not have the best ideas but any suggestion and a workaround would be appreciated.
There isn't a simple way to do that. Indeed, trying to set the servers there might a be way, but it's not a guarantee, since China Firewalls are constantly changing. You can try some onlines tools as this one here to verify if your domain is blocked, by adding the URL of your application.
Besides that, the best option is the one clarified in this other post here. You would create an API in Heroku and make the data and calls from Firebase go over this API, so it would make the connection. Another option you may try is using a proxy server - as very well explained in the article Firebase: Accessing Firestore and Firebase through a proxy server - so it gets complied and it's possible to be used in China.
The usage of VPN is not a very good option, as not of them work in China and the ones that work can easily vary, also, this could impact the usability, since it might affect performance and usage for the users there.
To summarize, there isn't a specific and fully correct answer to using Firestore in China, due to the fact that updates and changes on their rules are regular, but these are some alternatives that you can give it a try. It's more about trying the one that would be less damaging for your use case.
Let me know if the information helped you!

There is a Firebase alternative for China - Huawei Mobile Services. It contains services like Auth Service, Cloud Functions, Cloud DB, Crash, Push Kit, Ad Kit, and many more...
I am developing a flex 4.5 web based application and I need to make sure if the client chooses a certain level of security, each user can log only from an authorized computer.
So the question is how can I get some unique computer information? Anything like HDD serial number, CPU specifications, motherboard information, even the user that is logged into the Operating System can do.
So far the information on the web isn't giving me much hope that this can be achieved, but I had to ask.
Thanks in advance.
I suppose the only option available for web application is to create unique id from fields of flash.system.Capabilities class.
Other strategy which can be used is to generate unique UID in process of computer's authorization and then store it in local storage using SharedObject. Then web app tries to read authorization data from SharedObject on web app start. If there is no such data computer isn't authorized.
Richard is right. For security, unique identifying information is not available for applications running through Flash Player. You could write an Active X control (for IE) or a plugin (for Mozilla based browsers) to obtain additional information for your app if users (and their IT administrators) allow it. Information available will vary depending on the browser and operating system the user is running.
Adobe Air, on the other hand, allows access to additional network information including MAC address in the NetworkInfo class. Maybe it's worth considering an installed client app for users who require the additional security. Take a look at: http://www.adobe.com/devnet/air/flex/articles/retrieving_network_interfaces.html
This is not easy using a browser based Flex application, but there are some workarounds.
The browser based Flash Player can communicate with an AIR app on the desktop using localconnection. So, you could create an AIR app that utilizes NativeProcess to retrieve your machine specific information.
You could also use NativeProcess from a AIR app without using the browser at all.
A third option would be to install an application server on the client machine and have the browser based app communicate with the server to retrieve the client information.
I consider most of these options too difficult to be practical, but it depends on how important this feature is to you.
The Flash Player security sandbox will not let you read anything unique about the system on which the SWF is running, so I'm afraid this is not possible. The closest you will get is likely Capabilities.serverString along with maybe IP address, but the serverString property just lists all the capabilities of the client, which is obviously not a unique thing, and also might change from time to time for the same computer.
Warning: my knowledge of server-side scripting is limited to say the least.
This isn't a technical solution, but rather a different approach to your problem.
An alternative solution to would be to inspect the raw packet at the server in order to obtain data such as the IP and MAC address. Based on this the server can then deny or allow the login attempt.
I am used to working on embedded web servers running on micro controllers where C-based black magic is rather common, so I am not sure if this is possible or practical in a more traditional environment.
I have two applications which access camera and mic written in flex.When these two resources had to be used it ask flash player asks for the use of system resource Allow or Deny Is there any way to by pass this.In gmail->settings->chat->view settings it doesnt ask for this confirmation.How to code this
No, it's not possible to bypass this dialog. I couldn't find the gmail feature you were referring to, but I highly doubt that they have some way of working around this security barrier.
My company has a website product (ASP.NET) which is sold to customers. It means we don't host the website. They install it on their server and run it in the intranet.
I need to implement some sort of copy protection mechanism so that not everyone ends up installing the website. It has following aspects:
It has to be completely software based (no dongles).
Hiding usage information in registry or some folder in c:\ (basically outside virtual directory) is not an option for a website
Please can you suggest any scheme/method?
One suggestion is to use some kind of web service running, of course you need to have a main server to do so. In this server you can have some of your clients servers data (IP of the authorized servers, CPU and Motherboard ID's, and other important data).
This web service has to run some important logic of the program and return a value to the authorized servers. If the data of autorization sent by the client doesn't match, the server do will not execute the routine.
Of course I assume that this side of the logic is included in a DLL in the application and not in plain code.
A technique that worked well for a buddy of mine was to install a web bug on an administrative page which would report back to their server. You can monitor when and where the application is installed. It could be easily removed, but won't by most customers.
Simple, easy to do, and works relatively well.
Something you could try. Compile binaries for each client, obfuscate the code, lock the site down to a single domain. If its an internal app the domain might be something like "productname.clientname.internal". The app checks the domain of all the incoming requests, refuses anything that doesn't match.
As already pointed out by jeffamaphone: people will find ways around it, but it's enough to 'slow down' those not super determined.

Take a look at DeployLX. You can add licensing to your web based application to require one of a couple different options.
Hardware based locking so it can only be used on one machine.
Domain based locking so it's tied to a specific domain name.
IP based locking to tie it to an IP address.
License server locking to that your app checks in periodically with a centralized web service.
It's pretty flexible and should let you create a balance between protection and not frustrating your users.
We have a Microsoft web stack web site, we have a members database.
We want to start doing mass-emails to our (opted in) membership.
I don't particularly want to re-invent the wheel with a system for having a web form submit and then mass send emails looping through thousands of records without timing out and overloading the server...
I guess I'm looking for something like Mailman, that can run on a windows (ASP/ASP.NET + SQL Server) backend and do the work for me, with suitable APIs to manage the subscriber list and send emails to that list.
Suggestions please?
I agree with acrosman, third parties that host email lists are a good way to go. A very reliable site I've found for mass emailing is http://mailing-list-services.com/. They do a good job to make sure their servers are never black listed or marked as spam. I've used them a few times, their website design blows, but their service is awsome. The Lyris Listmanager software they use has a pretty extensive API.
Advanced Intellect has some great tools, like aspNetEmail and ListNanny.
MaxBulkMailer might be a solution for you? The organisation I work for uses it to connect to www.authsmtp.com which gives us credits for a certain number of e-mails that we can send per month. You can import a spreadsheet of your mailing list or tap straight into a SQL server and pull the names and addresses. Available for Mac and Windows.
(not a sales pitch)
my company offers mail manager, but it's a hosted service. It has a full API though.

Unless your running a business that specializes in email, I'd suggest you find a hosted solution. There are 100's of little issues that come up when you run your own service over time. A hosted solution can save you lots of time and effort (and therefore money).
