kandi X-RAY | Emu Summary
Emu is an open-source particle-in-cell code for solving the neutrino quantum kinetic equations in 1, 2, or 3 spatial dimensions with arbitrary angular resolution. It is part of the AMReX-Astro suite of astrophysical simulation codes. Emu represents the neutrino distribution function as a set of particles, each of which represent a collection of neutrinos and antineutrinos with unique position and momentum. Each particle carries two density matrices to define the flavor state of the neutrinos and antineutrinos it represents. Emu includes the vacuum, matter, and neutrino self-interaction potentials. We calculate the self-interaction potential using PIC deposition and interpolation algorithms that efficiently compute the local number density and flux at particle locations. Emu is implemented in C++ and is based on the AMReX library for high-performance, block-structured adaptive mesh refinement. Emu is parallelized with MPI + OpenMP for CPUs and MPI + CUDA for GPUs.

QUESTION
After successfully connecting my locally hosted (botkit-based) bot to Microsoft's Bot Framework Emulator (using a localhost address for the messaging endpoint), I'm now trying to connect it to the framework's webchat (using an ngrok's hostname for my local bot). However, I get an 'unauthorized' when webchat tries to connect. More on my bot:
- The bot integrates with the Bot Framework via botkit's own Botkit Framework Adapter (see https://github.com/howdyai/botkit/blob/main/packages/docs/core.md#using-bot-framework-channels for details) *The bot is hosted locally (dev version, which is the one I'm trying to test), and exposed via ngrok. Its production version will be hosted on AWS.
Here's what I've tried so far:
- Using methods #1 and #2 described in https://docs.microsoft.com/en-us/azure/bot-service/bot-service-channel-connect-webchat?view=azure-bot-service-4.0 to embed the webchat using an iframe with the provided webchat secret and also a token (obtained separately via POSTMAN).
- Using a modification of method #3 in the same web page, in which I obtained a Direct Line token instead (via POSTMAN) and then tried to use it in the html provided in there.
- I've also tried 'Test in Web Chat' in the Azure console.
In all those cases my bot's own log displays the same: "Experienced an error inside the turn handler Error: BotFrameworkAdapter.processActivity(): 401 ERROR Error: Unauthorized. Invalid AppId passed on token: blah".
The browser console shows different results for the last case compared to the website embeds as follows:
- (website embeds), I see a 502 in the browser's console, which I believe is expected given the 401 response from the bot (as explained by other sources).
- (Test in Web Chat'), I see several other errors in the browser web console in addition to the 502. One of those errors makes me think that perhaps 'Test in Web Chat' does not actually support non-Azure hosted bots (MsPortalFx/Base/Base.Net Base.Net: Security issue: Request to send auth token to untrusted domain 'myngrokhostname.scm.azurewebsites.net'. Only a fixed set of domains should be configured to receive auth tokens).
So here are my immediate questions:
- Does the 'Test in web chat' feature require an Azure-hosted bot?
- Given that I don't specify myself an appId and password when configuring the webchat channel (since it gets automatically configured), how could I be getting an error indicating that the wrong appId is being used? (note: the appId and password are part of the bot's adapter configuration as explained in the link I shared earlier; this is the only spot in which I entered them, and they were copied directly from the AzureBot configuration console)
Aside from the above questions, do you have any other suggestions on what could be wrong/missing in my environment? BTW, by now I believe I have read all of the similar posts that refer to 'unauthorized' errors while using webchat and none of them has helped so far, including those referenced in the first comment provided below. For the record, here are the posts (not mentioned in the comment) that I've also read:
- There was an error sending this message to your bot - Test in Web Chat
- Test in Web Chat typing message returns "Not found" HTTP status code after deploying bot to Azure
- Getting a 403 while connecting local bot to local WebChat client (works with Emulator though) (note: a comment in the last post suggests that I should be looking into offline-directline to get this to work; I may try this although I don't understand why it should be needed). Any further help would be much appreciated.
ANSWER
Answered 2022-Feb-03 at 12:27• I will suggest you to please check the below Github community forum for details on your issue regarding the turn handler and the ‘BotFrameworkAdapter.processActivity():401 ERROR’ in which they state that they tried to connect through two types by local bot: -
- By entering the URL, appID/password
- To select the bot which is defined by bot file from "My bots" form in the Welcome section.
In the above two types of connections made, the 1st one always fails while the 2nd one executes successfully always. So, according to them, they are suggesting downloading the latest version of Emulator over.
https://github.com/microsoft/BotFramework-Emulator/issues/1417
Kindly refer to it as it may be helpful to you. And as far as ‘Test in webchat’ feature is concerned, it does require an Azure hosted bot because the Bot Framework Emulator that runs on the local device has the Azure Bot service endpoint link embedded in its runtime configuration for which during the execution of the emulator, we have to enter the AppID and password of the Azure Bot service to connect to.

QUESTION
(full disclosure, this is a repost from my reddit post)
First of i'd like to state that i'm really not a developer and i'm a beginner in Rust. I have a question that may be trivial.
I'm working on implementing a emulator for a custom CPU. I'd like to be able to hook the emulation (and debug it later). I want to have separate crates for the CPU, hooking system and emulator and i want my CPU to not know implementation details of the hooking system and vice versa. But i'm having problems modeling that.
Right now, i have something like:
...ANSWER
Answered 2021-Dec-09 at 17:39I also cannot simply pass the
Cpuas a parameter to the closure because then, i would end-up with a cyclical dependency, theCpurequiringHookthat requireCpu.
Actually, this is the best solution. In other languages, it might not be, but in Rust, trying to have the individual hook functions remember emu will result in inability to do anything with emu because it is already borrowed. The general principle is that when you have an abstract circular relationship between entities like this (the Cpu owns Hooks, but the Hooks want to work with the Cpu), it is better to pass a borrow of one member of the relationship to the other than to try to have them permanently refer to each other.
Change your hook functions to have a signature like FnMut(&mut Cpu, VirtAddr) -> Result.
QUESTION
newbie here! I'm having a hard time learning the life cycle of fragments and I'm stuck in this problem. If I run this on the emu, the fragment is showing on the activity but the button inside the fragment needs to be clicked twice to run the destination activity.
FragmentSetting.kt: ...ANSWER
Answered 2021-Dec-06 at 01:17You are setting the Fragment class itself as the listener to both buttons when the view is created. That would be an acceptable place to do it.
However, your listener function doesn't perform your desired action of your button. Instead, it is setting a new listener for each button. So the first time they are clicked, they get their new listener. It is only in that inner secondary listener that you are going to another activity, so that's why it's taking two clicks.
You need to directly do your action instead of wrapping the action inside setting another listener. By the way, the view passed to a click listener is never null, so you can remove the ?'s.
