Its interactions with operation-level seeds is as

QUESTION
I had an issue where adding an extra pipe to subscription to a BehaviorSubject
was making the wrong behavior in some tests. Whenever I did const stores = await lastValueFrom(workingStore$);
in RXJS 7 or const stores = await workingStore$.toPromise();
in RXJS 6, the value was not what I expected. I reduced the code down to this fiddle: https://jsfiddle.net/Dave_Stein/v7aj6bwy/
You can see on the run without a concatMap
, getValue
gives 3 values in an array. With concatMap
, it will only return the first value.
The same can be observed when I use toPromise
in this way:
ANSWER
Answered 2021-Jun-11 at 17:13The solution is at: https://jsfiddle.net/Dave_Stein/nt6Lvc07/.
Rather than trying to subscribe to workingStore$
twice, I can use mergeWith
operator in RXJS 7. (There is another way to accomplish this in 6). Using subscribe on the same subject twice is a bad practice that can lead to issues like these apparently.
QUESTION
I'm using FastAPI and I need to represent different STIX 2 objects (from MITRE ATT&CK) with a corresponding/equivalent Pydantic model in order to return them as a response JSON.
Let's consider the AttackPattern object.
...ANSWER
Answered 2021-Jun-11 at 08:46A possible and promising approach is to generate the Pydantic model starting from the corresponding JSON Schema of the STIX object.
Luckily enough the JSON schemas for all the STIX 2 objects have been defined by the OASIS Open organization on the GitHub repository CTI-STIX2-JSON-Schemas.
In particular, the JSON Schema for the Attack-Pattern is available here.

QUESTION
I have a view hierarchy as shown in the image below.
I'm getting strange scroll behaviors like,
- If I scroll (drag slowly or fling) from Area 1 the
AppBar
collapses along with it. This is fine. - But if I drag slowly from Area 2 the
AppBar
does not collapse. It stays there andRecyclerView
goes beneath it. However, it works fine with a fling.

Answered 2021-Jun-09 at 09:27To fix this you need a couple of steps:
Wrap the outer
ViewPager2
in aNestedScrollView

QUESTION
I use a CollapsingToolbarLayout
and a BottomAppBar
reacting to scroll changes in a CoordinatorLayout
(collapsing and hiding on scroll). As I can't use a NestedScrollview
as parent of the RecyclerView
because it leads to issues when I need to use scrollToPosition()
or when an item is dragged out of the bounds (It doesn't scroll to move the item), the scroll behaviors are not working for the CollapsingToolbarLayout
and the BottomAppBar
.
I tried android:nestedScrollingEnabled="true"
but it was not working
How can I keep the scroll-related behaviors in the CoordinatorLayout
without NestedScrollview
?
ANSWER
Answered 2021-Jun-09 at 06:19Use android:nestedScrollingEnabled="true"
QUESTION
The model.eval()
method modifies certain modules (layers) which are required to behave differently during training and inference. Some examples are listed in the docs:
This has [an] effect only on certain modules. See documentations of particular modules for details of their behaviors in training/evaluation mode, if they are affected, e.g.
Dropout
,BatchNorm
, etc.
Is there an exhaustive list of which modules are affected?
...ANSWER
Answered 2021-Mar-13 at 14:22Searching site:https://pytorch.org/docs/stable/generated/torch.nn. "during evaluation" on google, it would appear the following modules are affected:
Base class Modules Criteria_InstanceNorm
InstanceNorm1dInstanceNorm2d
InstanceNorm3d
track_running_stats=True
_BatchNorm
BatchNorm1d BatchNorm2d
BatchNorm3d
SyncBatchNorm
_DropoutNd

QUESTION
I have a prime-ng table of shops, where I can remove and add shops to a list.
The behavior: When a shop is added, the ChildComponent
emits an event to ParentComponent
which then adds the shop to the list and updates the input observable of the ChildComponent
so that the shop no longer appears in the table.
The issue: The above behavior works fine except when the table is filtered, then when adding a shop the table is not updated even though I can see that the table array has been updated correctly in the component. However, when another shop is added (in the same filtered table) it works fine, and then both shops are removed from the table.
The table is part of a pure component (child):
...ANSWER
Answered 2021-Jun-08 at 11:21I followed the answer in this question and it worked for me, but I still don't fully understand why it didn't work on first addition then it worked on the next ones previously.
