            How to Subscribe to multiple Websocket streams using Muiltiprocessing
            Asked 2021-Jun-08 at 12:46

            I am new to handling multiprocessing, multithreading etc.. in python.

            I am trying to subscribe to multiple Websocket streams from my crypto exchange (API Docs Here), using multiprocessing. However, when I run the code below, I only receive ticker information, but not order book updates.

            How can I fix the code to get both information?
            What is the reason that only one websocket seems to be working when it's run on multiprocessing?

            (When I run the functions ws_orderBookUpdates() and ws_tickerInfo() separately, without using multiprocessing, it works fine individually so it is not the exchange's problem.)

            You have created two daemon processes. They will terminate when all non-daemon processes have terminated, which in this case is the main process, which terminates immediately after creating the daemon processes. You are lucky that even one of the processes has a chance to produce output, but why take chances? Do not use dameon processes. Instead:

            Pytorch Lightning duplicates main script in ddp mode
            Asked 2021-Jun-08 at 12:37

            When I launch my main script on the cluster with ddp mode (2 GPU's), Pytorch Lightning duplicates whatever is executed in the main script, e.g. prints or other logic. I need some extended training logic, which I would like to handle myself. E.g. do something (once!) after Trainer.fit(). But with the duplication of the main script, this doesn't work as I intend. I also tried to wrap it in if __name__ == "__main__", but it doesn't change behavior. How could one solve this problem? Or, how can I use some logic around my Trainer object, without the duplicates?

            Answered 2021-Mar-04 at 07:56

            I have since moved on to use the native "ddp" with multiprocessing in PyTorch. As far as I understand, PytorchLightning (PTL) is just running your main script multiple times on multiple GPU's. This is fine if you only want to fit your model in one call of your script. However, a huge drawback in my opinion is the lost flexibility during the training process. The only way of interacting with your experiment is through these (badly documented) callbacks. Honestly, it is much more flexible and convenient to use native multiprocessing in PyTorch. In the end it was so much faster and easier to implement, plus you don't have to search for ages through PTL documentation to achieve simple things. I think PTL is going in a good direction with removing much of the boiler plate, however, in my opinion, the Trainer concept needs some serious rework. It is too closed in my opinion and violates PTL's own concept of "reorganizing PyTorch code, keep native PyTorch code". If you want to use PTL for easy multi GPU training, I personally would strongly suggest to refrain from using it, for me it was a waste of time, better learn native PyTorch multiprocessing.

            Salesforce Knowledge Article Field - Not Visible to Guest User
            Asked 2021-Jun-08 at 10:51

            I am very new to Salesforce, so apologies if my use of terms is not correct.

            I am using Lightning Knowledge

            I have enable and setup Knowledge Base and added FAQ articles and have added Question and Answerr fields to those articles.

            I have setup the field visibilty so they are visible to all user including "Read Only" users (I could not find anything specific for Guests, should there be?)

            So as far as I can tell the field permissions on the Question and Answer fields is correct.

            I create articles and enter my values for my "Question and Answer fields" but when I go to my public site to view the FAQ, I only see the content of the Title and URL Name fields. I do not see my Question and Answer Fields.

            If I login and view the articles via the public site, I do see the Question and Answer values.

            I would very much appricaite it if anyone could point me in the right direction for trying to figure this out. I have googled but cannot seem to find anything that talks about guest users and field visibilty that has helped me.

            Many Thanks Derek

            Yes, guest user is still an user. There's hidden user account (which acts as "created by" when you make new Case for example) and Profile which you might have to edit. It doesn't show up on normal list of profiles (but for example the Id can be queried and once you know Id you could construct the url yourself).

            If you're using an Experience Cloud (aka Community) go to your site's Builder and the links will be at the bottom.

            If you're using Sites - it should be in Site's config.

            Angular 12 'ng serve' builds apps slowly, almost like production builds
            Asked 2021-May-28 at 19:38

            I've just migrated an app from Angular 11.2.7 to Angular 12. Everything runs fine, except that when I am developing and using 'ng serve', rebuild times are much, much slower now, to the point where it's frustrating.

            I'm on an M1 iMac, using node 16.1.0, for what it's worth.

            The machine was lightning fast at dev rebuilds (sub-second) before I moved to Angular 12. Now if I change just one line of code, even if I just change one letter in a console log, build times are 23 seconds, roughly 22 seconds of which are taken up with "phase: sealing".

            I've also noticed that everything now runs from a minified 'main.js" even when ng serving. I seem to recall version 11 didn't do that, but ran individual un-minified components during dev. Which is to say, ng serve now seems to be doing something like full a production build every time I change anything. I think that's the root cause of the slowness, but I'm not sure.

            So . . .

            Should I still be using 'ng serve' for development in Angular 12?

            Is there an option that needs to be set when you migrate, perhaps to turn off full minified rebuilds, to maintain the old build speed?

            What is this 'sealing phase', anyway? It sounds like a production build term to me!

            thanks

            Or as they like to call it:

            The aim of these changes is to reduce the configuration complexity and support the new "production builds by default" initiative.

            SalesForce query returns results in Query Editor, but returns null from APEX code in Lightning component
            Asked 2021-May-26 at 14:17

            I'm completely new to SalesForce and have inherited a report that's not working. Please excuse any incorrect terminology, since I'm learning about all this as I go. The report has three prompts: states, years, and members. All dropdowns are supposed to populate with data returned from functions in an APEX class. State, which populates from a picklist, and years, which is populated with a loop, work fine. Members, which populates from a SQL query, returns nothing. If I run the report without any prompts selected (which should return an unfiltered list of results from a SQL query), it also returns nothing. Both of the SQL queries return data when I execute them directly in the query editor in the developer console, but they return nothing when called from the APEX functions.

            Here's the initialization code from the Lightning controller:

            Edit

            Right, it's a public page, it's called "Salesforce Sites". It's exposed to whole world without having to log in. These have special security in place because most of the time you don't want to expose data like that. At best you'd display contact us form, maybe some documents to download, product catalog... It's all very locked down, default is to ban everything and then admin decides what's allowed. It's bit unusual to have a Visualforce page + Aura component but ok, it happens.

            You (and any other internal user) can see the results if you'd access this page from within salesforce. Something like https://mydomain.my.salesforce.com/apex/SearchBinReceiptsByYear and for you the page will work fine, "just" not outside of salesforce.

            When exposed like that on the web - there's no logged in user. There's special "[Site Name] Guest User", you can see them if you search "Sites" in Setup. It has a special profile, also with [Site Name] in it. And nasty thing is - it doesn't show on the list of Users or Profiles.

            Your code broke when Salesforce (auto)activated a critical update. Probably this one: https://releasenotes.docs.salesforce.com/en-us/spring20/release-notes/rn_networks_secure_perms_guests.htm There are some good resources on the net if you Google "Secure Object Permissions for Guest Users", for example https://katiekodes.com/salesforce-spring-20-guest-user/

            Ask your system administrator colleague or read up a bit about sharing rules.

            You'll have to go to Setup -> Sharing Rules. There's a checkbox that caused your stuff to break and you can't untick it.

            Scroll down to your TRC Account object and hit "New". You'll need to create something like this, but with your criteria (TRC Member equals true)

            Save, wait a bit (it might take a while to recalculate the sharing, you'll get an email) and try the page.

            If it still doesn't work you'll have to check the Guest user's profile, it might need permissions to Read TRC Accounts and their Name field.

            If it's Salesforce Sites - try this to find it: https://help.salesforce.com/articleView?id=000334554&type=1&mode=1

            If it's a Customer Portal, Community, Digital Experience (they renamed the product few times) - try with https://help.salesforce.com/articleView?id=sf.rss_config_guest_user_profile.htm&type=5

            Original answer

            It looks like it's running OK because accounts (members?) are fetched first and in that fetch's callback (what to do when data comes back from server) you have helper.getLocationState, helper.getYear. And you wrote that these populate OK. It's not the best performance code but it should get the job done.

            In no specific order...

            Does the whole thing work OK for sysadmins? Or is it broken for everybody? If it works for sysadmins it might be something to do with sharing, your sysadmin should know (Setup -> Sharing settings is where you control who can see what. Maybe "mortals" are not allowed to see any data? Typically sysadmins bypass it. As a quick & dirty test you can modify the class definition to global without sharing class DataTableLocations but it's a really ugly hack.

            What happens if you open DeveloperConsole (upper right corner) while running this component, do you see any errors in the logs? What happens if in the console you go Debug -> Open ExecuteAnonymous and run this piece of code:
