How can you tell a computer it is adding without addl in Assembly

Asked 2022-Apr-11 at 20:35

I know a bit about Assembly. So let me first introduce the codes, then explain my way of thinking.

Answered 2022-Apr-11 at 17:47

The compiler saw that you were adding two numbers 2 + 3. And the compiler calculated that 2+3=5 and it put 5 in the assembly code. This is called "constant folding".

I guess you have optimization turned off in your compiler since it didn't delete the useless variables a and b. But constant folding is very easy for the compiler (unlike other kinds of optimization) and useful, so it seems that the compiler is doing it even when you don't turn on optimization.

As you figured out, the assembly code does not add 2 and 3 because there is no addl or similar command. It just does return 5;

QUESTION

Android device shows microphone is actively being used even though session is paused and audio is disabled

Asked 2022-Apr-05 at 06:13

Start publishing to a session, notice that Android OS now reports that camera and microphone is being used by the app, which is fine.

Call session.onPause() followed by publisher.publishAudio = false.
(Optional) Move application into background by pressing Home button.
Android OS indicates that camera is no longer being used, but microphone is still being used by the application.

Although it does not affect usability of the app it is bad in terms of user privacy perspective - the user might think the app is still recording audio while it is in background, which is scary.

Is there other methods I can call to turn off the microphone access totally, just like the camera?

The key of an object has to be a string. You did it right in the object itself. But when you attempt to access it, the issue reappears.

If you insist on using it as it (maybe you do not have the choice), you have to use the square bracket notation:

Increment Number By Value With Condition - Array Formula

Asked 2022-Feb-02 at 09:58

i'm confused with the following condition, simply i want to have arrayformula or maybe a custom-formula to increment number in a way bound by specific condition based on value in other column, put it simply :

if the group doesn't change and sub-group is different increment number by 1
else if the group doesn't change and sub-group is doesn't change (same) hold value by previous
else if the group change regardless sub-group value reset number back to 1

for ilustration

** notes Number is the result that i want, in example i fill it manually

I have entered my solution in cell D1 of the sheet "Erik Help." As I said in the comments to your original post, this is a more complex solution than I can generally offer here on the free, volunteer-run forums. I did choose to develop and share the formula with you, but I will need to leave it to you (and any other future site visitors who may be interested) to study the formula for understanding how it works. Explaining the formula would take longer than writing it.

Here is the formula:

=ArrayFormula({"Number"; IF(A2:A="",,VLOOKUP(LOWER(A2:A&B2:B),QUERY({UNIQUE(FILTER({A2:B,A2:A&B2:B},A2:A<>"")),COUNTIFS(QUERY(UNIQUE(FILTER({A2:B,A2:A&B2:B},A2:A<>"")),"Select Col1"),QUERY(UNIQUE(FILTER({A2:B,A2:A&B2:B},A2:A<>"")),"Select Col1"),SEQUENCE(COUNTA(QUERY(UNIQUE(FILTER({A2:B,A2:A&B2:B},A2:A<>"")),"Select Col1"))),"<="&SEQUENCE(COUNTA(QUERY(UNIQUE(FILTER({A2:B,A2:A&B2:B},A2:A<>"")),"Select Col1"))))},"Select Col3, Col4"),2,FALSE))})

Yes. I agree it is ugly. You can create a service that is just responsible to execute some codes in a transaction . Same idea as TransactionTemplate but it uses @Transational to manage the transaction.

CrashLoopBackOff on postgresql bitnami helm chart

Asked 2022-Jan-04 at 18:31

I know there have been already a lot of questions about this, and I read already most of them, but my problem does not seem to fit them.

I am running a postgresql from bitnami using a helm chart as described below. A clean setup is no problem and everything starts fine. But after some time, until now I could not find any pattern, the pod goes into CrashLoopBackOff and I cannot recover it whatever I try!

Helm uninstall/install does not fix the problem. The PVs seem to be the problem, but I do not know why. And I do not get any error message, which is the weird and scary part of it.

I use a minikube to run the k8s and helm v3.

Helm chart: https://artifacthub.io/packages/helm/bitnami/postgresql/10.9.5

Answered 2022-Jan-04 at 18:31

I really hope nobody else runs across this, but finally I found the problem and for once it was not only between the chair and the monitor, but also RTFM was involved.

As mentioned I am using minikube to run my k8s cluster which provides PVs stored on the host disk. Where it is stored you may ask? Exaclty, here: /tmp/hostpath-provisioner/default/data-sessiondb-0/data/. You find the problem? No, I also took some time to figure it out. WHY ON EARTH does minikube use the tmp folder to store persistant volume claims?

This folder gets autom. cleared every now and so on.

SOLUTION: Change the path and DO NOT STORE PVs IN tmp FOLDERS.

They mention this here: https://minikube.sigs.k8s.io/docs/handbook/persistent_volumes/#a-note-on-mounts-persistence-and-minikube-hosts and give an example.

But why use the "dangerous" tmp path per default and not, let's say, data without putting a Warning banner there?

Sigh. Closing this question ^^

QUESTION

The only way to get a File object by letting the user choose a file is MANAGE_EXTERNAL_STORAGE?

Asked 2021-Dec-24 at 18:05

I want to show a file browser to the user, let him choose an arbitrary file he wants, and read it using the ZipFile class. The class requires a File object, not an InputStream.

If my research is correct, the in-built file choosers (ACTION_OPEN_DOCUMENT, etc) only provide a stream, not a File, right? Even if I get the file name from the chooser and have acquired READ_EXTERNAL_STORAGE from the user, it seems that in recent Android versions, the API only allows "only media" and reading files of other types seems to fail.

If I have also acquired MANAGE_EXTERNAL_STORAGE, then it works, but that shows a scary warning like following to the user.

Allow this app to access, modify, and delete files on the device or any connected storage devices? This app may access files without asking you.

That seems to be an unnecessarily broad permission when all I want to is a read-only access to File for a file that the user has explicitly chosen in the file browser. There is no other way than acquiring MANAGE_EXTERNAL_STORAGE, is that right? I want to make it sure, because it sounds weird. Even a very restricted environment like a web browser, the browser does not require any special permission or show any warning for reading a file that the user has explicitly selected, and the same was true for UWP app.

If my research is correct, the in-built file choosers (ACTION_OPEN_DOCUMENT, etc) only provide a stream, not a File, right?

Correct. After all, the user can choose something that you cannot access via the filesystem, either due to permissions or due to the fact that it simply isn't on the filesystem (e.g., cloud storage, SMB/CIFS file server).

IOW, what you refer to as "file choosers" are not limited to what you seem to be thinking of as files.

If I have also acquired MANAGE_EXTERNAL_STORAGE, then it works

I do not know what "it" is. You cannot hack into Google Drive to get a File object using MANAGE_EXTERNAL_STORAGE, for example. Nor can you get a File object for a document contained as a BLOB in an encrypted database, etc.

There is no other way than acquiring MANAGE_EXTERNAL_STORAGE, is that right?

You cannot do what you want even with MANAGE_EXTERNAL_STORAGE. A Uri is not a file.

Your options are:

Copy the content identified by the Uri to some file that you control (e.g., in getCacheDir()), so you can use ZipFile.
Relax the ZipFile constraint. For example, perhaps you could use ZipInputStream, or find a third-party ZIP reader that supports InputStream (such as this or this). You can get an InputStream on the content identified by the Uri via openInputStream() on ContentResolver.
Relax the "in-built file choosers" constraint, and implement your own "file chooser" with files that your app can read on the filesystem. That way, you are guaranteed that you can use File, since you used File to get to them in the first place.
