kandi X-RAY | fuser Summary
FUSE-Rust is a Rust library crate for easy implementation of FUSE filesystems in userspace. FUSE-Rust does not just provide bindings, it is a rewrite of the original FUSE C library to fully take advantage of Rust's architecture. This library was originally forked from the fuse crate with the intention of continuing development. In particular adding features from ABIs after 7.19.

QUESTION
The following code does everything I want: pulls email, saves attachments, extracts files EXCEPT save the original email to the folder fDest. I seem unable to see the solution.
This seems to be the problematic line as it won't save the email: "mi.SaveAs fDest2, olMSG"
...ANSWER
Answered 2021-Jun-15 at 19:38You must be sure there are no invalid characters in the filename. See What characters are forbidden in Windows and Linux directory names? for more information. So, I'd suggest using the Replace
method available in VBA before passing anything to the SaveAs
method.
Another point is that you need to specify unique file names to each email. Make sure the generated file name is unique for a folder.

I thought it's easy to deploy a python api project to somewhere. BUT I was wrong, I cannot deploy to any platforms.
So far I have tried:
- Azure, Webapp and Function App
- PythonAnywhere
- Heroku
They all have issues when I'm trying to install dependency packages for this one:
scikit-fmm
here is the error message:
Python Version is 3.7.10 Linux
...ANSWER
Answered 2021-Apr-22 at 03:46UPDATE
After my test, because the latest version of scikit-fmm
is not compatible with azure web app, I used the scikit-fmm==2021.1.21
version. It works for me.
Thanks for Glenn's reminder, you can use below cmd in webssh.
QUESTION
Im trying to make a user recyclerview in a fragment, but i can't make it to work.
The idea is to get the users from the database (except for the actual user loged in) and add the user data to the list. The problem is that the list doesn't even apear.
I don't know much about Kotlin, i've recently started and Im struggling with this. Also I don't know where the problem is.
If you need the XML, ask for it

...ANSWER
Answered 2021-Mar-12 at 16:26The problem is that when you use your adapter the list is empty, then maybe 0.2 seconds later, you have fetched the users from the database and populated the list, but the adapter doesn't know the list has changed. After you have populated the list you can call notifyDataSetChanged()
on your Adapter to let it know the list has changed.
QUESTION
I have a bit of a problem with my program's login function. The function takes input from 2 TEdits from the login form (with each being for the Username and Password respectively) then compares the input to the records within the database it's supposed to read from (I use a separate class for this). The problem is whenever there's more than 1 record in the DB or when a new record was added, it just reads a random record in the DB and then logs in after trying 2 or 3 previous times to log in and failing each time. But when there's only one record in the DB, I can log in just fine? What am I doing wrong?

QUESTION
I want to get my data with two nested database query after taking the whole daha with this process. I want to set it into my useState but useState always set []
. I know that this is about async process but how can I fix it?
ANSWER
Answered 2021-Feb-15 at 21:45The problem is that calling .forEach
with an async function won’t wait for the function to finish for each element before moving to the next line.
As a consequence, your setState
is executed before the followers
array is filled. To fix this issue, use .map
instead of .forEach
, and wrap your “loop” inside a Promise.all

QUESTION
This is under Ubuntu 20.04. There's a script that appends to a file via shell redirection. I want to read that file after the script's process has ended and all data has been written. I'm using pgrep to check when the script ends (I have carefully checked that this check works). I have noted that the file may not be fully written even if the process ended.
Because of what I have read, this can happen because of buffering. A side question would be: can this actually happen or am I misunderstanding something?
I'm thinking on using lsof/inotifywait/a loop with fuser to await the file closing. Is this the right wait to manage this situations?
What I don't really understand is: if the process that opened the file exited, who will show as the file "opener" on lsof/inotifywait/fuser output?
...ANSWER
Answered 2021-Feb-14 at 15:17If you're worried about the file not having been written to disk due to buffering and it's in a process where you don't have the file descriptor, you can force the system to write them to disk with the sync
command or sync
function in unistd.h
.
QUESTION
I am building a Chat application using Firebase database. I have been able send and receive chats, I have also been able to get the users contacted under java class ChatsActivty The problem i s that the users in my ChatsActivity are only ordered alphabetically even when a new message is sent or received i.e. onDataChange, the list remains the same. I want user latest contacted to appear on top every time a message is sent or received.
My code is as shown below:
ChatsActivity.java
...ANSWER
Answered 2021-Feb-09 at 09:08Currently, you are querying your realtime database and ordering by its key name. To sort the RecyclerView list, you can try two approaches from here:
- Querying in such a way that you get results ordered by the last message timestamp.
- Manually process and sort at the RecyclerView adapter to display latest chat at the top.
For approach one, you can try using your query like this:

...ANSWER
Answered 2021-Jan-26 at 15:28It looks like users.getImageURL()
is returning null
for one or more of your nodes. If this is indeed a common occurrence in your database, you can easily detect by using so-called Yoda-notation for your check:
