Why "Google Play Services for AR" is incompatible with MI A1?
Is there any way to install Google Play Services for AR on a Xiaomi MI a1 device?
Thanks
ARCore need specific certification process to be certificated.
Mi A1 is not only supported list.
Please check whether your device is supported.

Apple's explanation of the export compliance is rather difficult to understand and a complete mix of IT and Law-Knowledge making it difficult to connect to the correct people.
Our app uses:
Libsodium (using a flutter library, so not apple-default-encryption but open source)
Https/SSL/... which require no uploads to app store connect.
I couldn't find out if Libsodium is
- is accepted by international standard bodies (such as IEEE, IETF, or ITU)

I am new to biometrics. I bought a new Persona U are U 4500 Device and SDK from a vendor. The SDK has some samples (as expected). All of the samples run smoothly except the WebSample. it do not detects my device in addition it gives an error in the console.
Can anyone please help me how to fix this issue and guide me as why am i facing this problem? is it something related to my wss://localhost?
Update
By further diving into the program i found the specified url https://127.0.0.1:52181/get_connection in websdk.client.bundle.min.js when i opened the link it says
{
"code": -2147024894,
"message": "The system cannot find the file specified."
}
Am i missing some file?
I don't have it in front of me now, because I switched back to the U.are.U 2.2.3 SDK, which does not have this feature.
But it sounds like you possibly have not installed the Digital Persona Lite client component. This runs a separate WebSocket service on port 9001 (IIRC) through which the JavaScript client then communicates.
It is described here: https://hidglobal.github.io/digitalpersona-devices/tutorial.html
After installation, you will need to restart.
The call to https://127.0.0.1:52181/get_connection should then respond with details of the WebSocket service, to which the JavaScript client will connect.
NOTE: The WebSkd library requires DigitalPersona Agent running on a
client machine. This agent provides a secure communication channel
between a browser and a fingerprint or card device driver. The
DigitalPersona Agent is a part of a HID DigitalPersona Workstation. It
can be also installed with a DigitalPersona Lite Client. If you expect
your users do not use HID DigitalPersona Workstation, you may need to
provide your users with a link to the Lite Client download, which you
should show on a reader communication error:
A link is provided there to download the Lite client from here: https://www.crossmatch.com/AltusFiles/AltusLite/digitalPersonaClient.Setup64.exe
you just add a script call of the following code "crossorigin = '' ". "crossorigin=''". It will look like this:
<script src="scripts/websdk.client.bundle.min.js" crossorigin="*"></script>
<script src="scripts/fingerprint.sdk.min.js" crossorigin="*"></script>
Corda has specific configurations mentioned for every HSM that they support. I have tried finding a way to directly configure the node to use softhsm. But I havent been able to find any thing for Corda to work with softHSM.
Hyperledger Fabric has a config (https://hyperledger-fabric.readthedocs.io/en/release-2.0/hsm.html) that works with softHSM.
Any ideas on if Corda can support softHSM and if yes what are the configurations?
we currently do not support SoftHSM. We currently support:
Utimaco
Gemalto Luna
Futurex
Azure Key Vault
Securosys Primus X
nCipher nShield
Please refers to this list of supported HSM to use with.

I want to use Apple and Google's new APIs to support Covid contact tracing as desribedin this API document. But when I try to use these APIs in XCode, the classes are not found:
let request = CTSelfTracingInfoRequest()
How do I enable these APIs?
The APIs for iOS are restricted. While you can write code against the ExposureNotifcation framework using XCode 11.5 and iOS 13.5, you can't run the code even in a simulator without Apple granting you a provisioning profile with the com.apple.developer.exposure-notification entitlement. And Apple is only giving that entitlement to developers associated with government health agencies after a manual approval process.
Below is more information on what you can do without special permission from Apple.
iOS releases prior to 13.5 disallowed transmitting the Exposure Notification Service beacon bluetooth advertising format in the specification. Starting with 13.5, advertising is possible only by the operating system -- 3rd party apps cannot emit that advertisement without using higher-level APIs.
Starting with iOS 13.5, Apple also blocks direct detection of this beacon format by third party apps, forcing them to use higher-level APIs. Earlier versions of iOS do allow detection of this beacon format.
Android, however, is another story.
While Google has similarly restricted use of these APIs in Google Play Services to API keys with special permissions granted from Google, Android versions 5.0+ allows 3rd party apps to both sending and detect the Exposure Notification Service beacon advertisement that the bluetooth specification envisions:
Using the free and open-source Android Beacon Library 2.17+, you can transmit this beacon like this:
String uuidString = "01020304-0506-0708-090a-0b0c0d0e0f10";
Beacon beacon = new Beacon.Builder()
.setId1(uuidString)
.build();
// This beacon layout is for the Exposure Notification Service Bluetooth Spec
BeaconParser contactDetectionBeaconParser = new BeaconParser()
.setBeaconLayout("s:0-1=fd6f,p:-:-59,i:2-17");
BeaconTransmitter beaconTransmitter = new
BeaconTransmitter(getApplicationContext(), contactDetectionBeaconParser);
beaconTransmitter.startAdvertising(beacon
And scan for it like this:
BeaconManager beaconManager = BeaconManager.getInstanceForApplication(this);
beaconManager.getBeaconParsers().add(new BeaconParser().setBeaconLayout("s:0-1=fd6f,p:-:-59,i:2-17"));
...
beaconManager.startRangingBeaconsInRegion(new Region("All Exposure Notification Service beacons", null));
...
#Override
public void didRangeBeaconsInRegion(Collection<Beacon> beacons, Region region) {
for (Beacon beacon: beacons) {
Log.i(TAG, "I see an Exposure Notification Service beacon with rolling proximity identifier "+beacon.getId1());
}
}
On Android, the above transmission and detection is possible even in the background. See library documentation for details.
The ability to transmit and receive Exposure Notification Service beacons is built into the BeaconScope Android app. You can use this as a tool to help test any apps you build.
You can read more in my blog post which shows you how to build your own app to do this.
As for iOS, while transmission is impossible as of this writing, you can scan for these beacons on iOS 13.4.x and earlier with code like this:
let exposureNotificationServiceUuid = CBUUID(string: "FD6F")
centralManager?.scanForPeripherals(withServices: [exposureNotificationServiceUuid], options: [CBCentralManagerScanOptionAllowDuplicatesKey: true])
...
func centralManager(_ central: CBCentralManager, didDiscover peripheral: CBPeripheral, advertisementData: [String : Any], rssi RSSI: NSNumber) {
if let advDatas = advertisementData[CBAdvertisementDataServiceDataKey] as? NSDictionary {
if let advData = advDatas.object(forKey: CBUUID(string: "FD6F")) as? Data {
let hexString = advData.map { String(format: "%02hhx", $0) }.joined()
let proximityId = String(hexString.prefix(32))
let metadata = hexString.suffix(8)
NSLog("Discovered Exposure Notification Service Beacon with Proximity ID\(proximityId), metadata \(metadata) and RSSI \(RSSI)")
}
}
}
Beware, however, that Apple blocked this from working as of iOS 13.5 beta 2. The didDiscover method above is never called for advertisements with the Exposure Notification Service UUID.
Full Disclosure: I am the lead developer on the Android Beacon Library open source project and the author of the BeaconScope app built on this library.
EDIT April 26, 2020: Updated answer above to link to the revised 1.1 version of the Exposure Notification Service Bluetooth Spec, to update naming conventions from that change, and to revise code samples to show the metadata.
EDIT April 30, 2020: Updated answer based on Apple's release of iOS 13.5 beta 2 and XCode 11.5 beta, and the fact that Apple now blocks 3rd party apps from detecting the Exposure Notification Service beacon.
EDIT June 2, 2020: Updated answer based on Apple's final release of iOS 13.5 and Google's release of Google Play Services.
You also may use other open-source contact tracing protocols like Apple/Google's.
For instance OpenCovidTrace – it is an open source implementation of the Google/Apple protocol with minor changes, or DP-3T – it is a protocol proposed by european science community.
I am looking to connect my TI MSP430+CC3000 eval kit to Xively for evaluation. There is a Xively C library that I would like to use. However, i wondering if anyone else has already done it who could share with me? As I saw there is already Xively feed with MSP430+CC3000 on-line.
Thanks!
The TI wiki has had a "CosmCloudApp" page for some time, but recently it's been deleted. The link here is to a previous revison of that page. Since there are quite a few public feeds when you search for "CC3000" it may be the case that TI have shipped this example at one point, but I was unable to find the source code or binary on TI website and according to the TI E2E forum it's nowhere to be found for quite a while.
After having a quick look at the SimpleLink API Reference Manual (download zip), I can see that it provides BSD-style socket API. Therefore it should be relatively easy to port Xively C library to CC3000 API using provided POSIX communiction layer.
