I have a use case where I need to get the last x incoming/outgoing calls to the mobile.
Is there a direct way to do it? (I would imagine that will require permissions)
And if not, how would I start on this?
Note that I prefer a way to do it on Forms instead of platform specific code if possible as I need it for both Android and iPhone devices.
Thank you for your help.

This question might be trivial, unfortunately I haven't found the answer I was looking for.
I used dpct migration tool to port some cuda code to Intel DPC++ and then I further optimized everything I needed and eventually got rid of everything related to dpct expect the super handy
dpct::get_current_device();
which basically solves all the previous pain I had to put compile options to select the appropriate device and control them with Makefiles and so on.
Is there any way to do this without using dpct ?
I had a look at how dpct does this (here) but it looks pretty non-straightforward and it relies on other internal functions.
Is there any way to avoid this ?
I'm not totally clear from your question whether you want to 1) grab a handle to your device or 2) select a device on which to run stuff, so I'll try to answer both. Note that dpct::get_current_device() isn't actually selecting a device, it's just returning the device which you have already selected earlier in your program.
Typically when using SYCL we start with a sycl::queue, which we use to submit kernels, memory copy operations etc. From a sycl::queue you can access your device with:
sycl::device d = q.get_device();
But it seems like you may instead be asking for the simplest way to select a device. In this case, the simplest approach is to construct your queue with one of SYCL's provided device selectors:
sycl::queue q{sycl::gpu_selector()};
sycl::queue q{sycl::cpu_selector()};
sycl::queue q{sycl::default_selector()};
Note that the last option (sycl::default_selector()) is probably what dpct is currently doing for you.
I have this project where I need to know if a visitor legitimately arrived from a QR code. Document.referrer value from a QR code shows blank. I have looked at some answers suggesting to put parameter in the query string (e.g. ?source=qr), but anyone could easily add the parameter into the URL and my code would believe it is from a QR code (e.g. www.project.com/check.page?source=qr) . I have thought of adding codes to make sure it is from a mobile phone / tablet as secondary way to authenticate but many browsers have add-ons to fool websites.
Any suggestions would be greatly appreciated.
Thanks in advance.
I think the best solution for you is creating your regional QR Codes pointing to:
Region 1) http://example.com/?qr=f61060194c9c6763bb63385782aa216f
Region 2) http://example.com/?qr=731417b947aa548528344fab8e0f29b6
Region 3) http://example.com/?qr=df189e7f7c8b89edd05ccc6aec36c36d
if the value of the parameter qr is anything other than f61060194c9c6763bb63385782aa216f, 731417b947aa548528344fab8e0f29b6 or df189e7f7c8b89edd05ccc6aec36c36d, then you can ignore it and assume the user didn't come from any QR Code.
Of course, any user can remove the source parameter. But at least he can't add a valid one, unless he really had access to the code.
...but anyone could easily add the parameter into the URL and my code would believe it is from a QR code
Well, anyone could also scan the QR code, view the link, and remove the source=qr from it.
Data collection is never 100% reliable. Users can change their browser's user agent, inject cookies with some strange values, open your page through a proxy server, and so on.
You could create your own device or App for scanning the QR-code. If you read the post I've linked, you will see that this is a waste of time and resources.
So, what is left is to make a solution which will work for most of the users. Appending a source=qr parameter to your URL seems to be the simplest solution. You could also link to an entirely different domain and redirect the request, so it would be more fraud-safe. But it will never be 100% accurate.
I'm using tdlib and currently trying to create another user's profile screen like this one:
There is usually a field on this screen called "Notifications" containing information on whether or not notifications for given user are muted and if so then for how long. All other fields seem easy to retrieve, but this one is a head-scratcher for me.
All other field are stored in User entity, but what am I supposed to do with this one? Call createPrivateChat only to get one field (namely notificationSettings)? This seems like overkill to me. Isn't there easiest ways to get this? In this issue sapelkinAV states that "chatID is equals UserId". Is it correct? Even if so it might just be an internal thing that we shouldn't rely on, and I can't find neither proofs nor restrictions on abusing this "feature".
If it is fine, than I could use getNotificationSettings and pass notificationSettingsScopeChat as scope parameter. Would it be the right solution? Any thoughts and advices are appreciated!
Official answer (obtained from TDLib bot):
Your usage of createPrivateChat is absolutely correct. To get correct NotificationSettings you need to get information about the corresponding chat.
So I ended up doing exactly that.
Call createPrivateChat only to get one field (namely notificationSettings)?

I made a c# script then change the MonoBehavior to NetworkBehavior
then pud the script in the Main Camera.
I have problem using NetworkBehavior I dont know how to execute it, I want to try the SyncVar and other attributes that can help about server-client data networking.
thanks.
It is difficult to tell what is going on from you picture, and it would be helpful if you could tell us exactly what you are looking for, but as far as SyncVar working, it is important to note that it only works from the server side. That is, you can't sync an attribute from a remote player to the server, but the server can sync a player's attribute to everyone else. another thing to note about sync var is that it only works on basic types and unity math types (quaternion, vector3, etc.) if I recall correctly. If you need more help please try to be more specific.
I hope someone could give me a quick example how to configure the BTLE-Device correctly without the huge BLE-Manager library. Simply a litte GAP Authetication and one GATT-Service would be enough to start. I've managed to create my own GATT-Service and characteristics without the need for BLE-Manager but thanks to several defines, typedefs etc. I can't figure out how to do this for GAP and how to register my callbacks for it. Maybe someone has used these modules before and can give me a quick example how it's done?
Since you mentioned One GATT-Service with Authentication Atmel-BAS [Battery Service] example is easy one. To better understand you can download the getting started guide see the architecture. In-order to register the callbacks you need to check the order of callbacks in function ble_event_manager in ble_manager.c file.
