i want to know if it is possible to make a security key out of a normal usb.
i am using webauthn api for php at the moment on a windows 10 device, if you take a quick look at the demo of webauthn and try to register with an usb it wont recognize it as an security key. is there any way to fix this?
i tried using windows aplications like usbRaptor but those will only lock my pc.
Not sure what "a normal USB" actually means, but you need a purpose-built FIDO security key for FIDO2/WebAuthn.
There are many vendors including SoloKeys, HID, Yubikey, TrustKey, and many others. https://fidoalliance.org/certification/fido-certified-products/

I want to implement app-to-app communication across a WP8 device and a Windows 8 device. I can't rely on Internet connectivity so any web server is out of the question. Additionally I don't want to use any local server to avoid setup overhead.
The most likely scenario is to use Bluetooth connectivity to pair and send small data sets between devices. I know that App-To-App communication between two WP8 devices, or two Win8 devices can be easily achieved using PeerFinder. However, I need to do cross-device.
MSDN documentation suggests that using PeerFinder.AlternateIdentities will allow this to happen, but it seems to require a tap gesture using NFC-capable devices. In my case, I want to be able to establish the communication without having to rely on the NFC Tap gesture.
The problem is that even setting and using AlternateIdentities doesn't seem to enable the devices to see each other. Digging deeper into the code, seems that Win8 devices require WiFi Direct to advertise and establish connectivity, which is not supported by WP8 devices.
Has anyone been able to solve this issue, or implement this scenario?
According to other threads, the only clear answer (although it doesn't work) is:
app-to-app / WP8-to-Win8. Using specific AlternativeIdentities on both ends it's also possible to get app-to-app to work for WP8-to-Win8. You'll need to set PeerFinder.AlternateIdentities["WindowsPhone"] on Win8 to the WP8 app GUID, and you'll need to add PeerFinder.AlternateIdentities.Add("Windows",GUID) on WP8 to the Win8 app GUID.
Thanks in advance.
Since FindAllpeersAsync function of PeerFinder uses WiFi Direct to do the peer discovery in Windows 8, and Bluetooth is used in the Windows Phone version, they are note compatible.
So, as for now, the following statement,
app-to-app / WP8-to-Win8. Using specific AlternativeIdentities on both ends it's also possible to get app-to-app to work for WP8-to-Win8. You'll need to set PeerFinder.AlternateIdentities["WindowsPhone"] on Win8 to the WP8 app GUID, and you'll need to add PeerFinder.AlternateIdentities.Add("Windows",GUID) on WP8 to the Win8 app GUID.
is basicallly false.
I've got a Windows 8 Professional device which has got a Mobile Broadband adapter embedded and I need to be able to send AT commands to the modem, usually I'd connect to the COM port and send the commands. However the device doesn't appear to have any COM ports, instead it presents its self as a network adapter.
I'm wanting to send AT commands to change the APN of the modem and to reset the device, I've looked into the 'netsh mbn add profile' but this command always returns an error advising that the XML profile is incorrect.
Also from looking at the functions of the netsh mbn it doesn't seem to provide as much control as sending AT commands.
The modem that I'm trying to interface to is the Ericsson C5621 GW on a Lenovo ThinkPad Tablet 2.
Is there another way to send AT commands?
Thanks
I do not know this product in particular, but since I worked in Ericsson, later in ST-Ericsson with mobile phone development for over a decade it is doomed to have some of my code in it so I'll answer on a general basis.
Short version is, no unless the device exposes a serial interface over one of the external interfaces (possible interface types are RS-232, IrDA, Bluetooth, USB or CAIF), there is no way of sending AT commands to it1.
Being an embedded device in a laptop and
your since you say it seems to be without serial interfaces I assume it uses CAIF (commonly used in embedded settings. It could also have be using USB with the serial interfaces disabled, but since this press release mentions that it will be available in a version with PCI interface, that is very unlikely). And thus unless the device is set up with any active VEI channels, there is no ways in for AT commands.
There might be other ways of changing the APN though.
1 We had a debug mechanism to inject AT commands onto arbitrary serial interfaces, but this itself was running on a serial interface, started by an AT command. And besides it will not be present in released products.
We are currently planning to develop a suite of Windows Store Apps. They are independent and fully work alone, but they are related and act in concert. If a user has several of them, they should share some of their settings (and data), so that the user does not have to manually change these settings in every single one of them.
Is such a scenario even intented?
And how to implement it?
Registry: Does not work. Apps cannot access the registry.
ApplicationData (LocalFolder, LocalSettings etc.): Does not work. Apps cannot access the data of other apps.
Cloud services: Kind of works, but only when the machine is online. Our apps should work offline, too. And we would need to create/rent such a cloud service, which would cause additional costs.
KnownFolder.DocumentsLibrary: This –currently– looks like the only solution to me. The apps are already saving and sharing data there, so let's just save our settings there, too. But the name of the shared folder is one of the settings! And Windows Store Apps cannot create hidden files, so the user can see the settings file. This makes this solution a bit... "rough".
Any other ideas or additional information I have missed?
If you want them to sync with each other instantly, even when the device is offline, then that's your only option. Windows 8 Apps are not intended to share settings.
So much want of sharing.
Roaming API will only share with the SAME app, the SAME user, ANY W8 device.
SkyDrive will only share across ANY app, the SAME user, ANY device.
Using Azure (or any web service) will share across ANY app, ANY user, ANY device.
Don't do this
Don't use the register, the API is not supported
Don't use the file system, the boundaries cause your app to be brittle
Don't use ApplicationData.AnyFolder, this is restricted to a single app GUID
You had might as well get "instant" out of your language, man. That just doesn't happen. But you can have fast (let's call it near instant); you can use Sockets or SignalR to connect your client to some service out there with nearly instant responses. A less sophisticated approach would be to poll from your client, too. It has served developers for decades.
I have a local installation of Voxeo's Prophecy platform, and a voice xml application that runs on the voicexml browser of the platform. How can i call the application to listen to the message, without having a sip phone, and without using the voxeo's hosting capability? I just want to call the application at the local installation without using a phone. When i try this from the browser, i just get the xml file containing the dialog.
Why are you trying to start the application without a SIP phone? The developer version of Prophecy comes with a SIP phone that works great for testing and debugging. Are you trying to access the application from a regular telephone or POTS. If that is the case you will need additional hardware, such as a Cisco VoIP Gateway to translate the land-line signal to SIP. There are a number of VoIP Gateways available. Another option is to put Dialogic cards in your server and use a software that translates between SIP and the Dialogic API. If you purchase Prophecy from Voxeo as an appliance there are options they can sell you to achieve this. The advantage of getting this from Voxeo is that they will help configure it, which is not trivial depending upon the type type of telephone lines you are using and whether they are behind a PBX or not.
The telephony/communications interface to Prophecy is SIP so that is the only way to communicate with it. You could use any open source SIP stacks to develop something yourself, but the easiest thing to do is to use a software based SIP phone. It is not like you could just start talking and the VXML app would know what you intended, or if the if the voice input was really intended for the VXML app. You still need to maintain things like sessions and routing to the correct application which is easily handled by a SIP phone. Prophecy is designed for a telephony environment. If you are trying to use it for something like a home automation system, which some people have, I would think you would have to provide some type of SIP front end that is voice activated.
Does anyone know of an open source web service/wcf service that can stream media content to clients? In particular I am looking for something that could access my music collection and stream it to a client (could be a client browser, win mobile app or even iphone application).
I guess it would have to be WCF based as I'm not sure that webservices do streaming really well. Also Windows Media Streaming Services is not the best way to go as the service should operate from a vista/xp machine (preferably).
If not, does anyone know the best way to start going about creating something like this - I'm not sure I know where to start with this one, although I can see many many uses for such a service!
Even though it's not open source, Windows Server 2008 has a Streaming Media role that will do what you ask. Of course, you'll need to have a server to put it on.
I tried Orb and it is quite good, apart from the fact that it hijacked my tuner card so media center would no longer work. However I'm going to try and create a home grown version.
Orb (www.orb.com) will stream your media to just about anything with a web browser. I've been running it on an XP virtual machine for about a year. I love being able to stream my entire media collection to my phone while I'm working at a client's site.
While it isn't open source, it is free and relatively well supported. One of the best features is that the architecture is set up so that there are no special requirements for your firewall -- it just works.
