kandi X-RAY | secure-data-share Summary
Ethereum has a nice property of everyone using it having to have a public/private key pair. This infrastucture can be leveraged to share data with multiple parties in an encrypted manner. In the spirit of minimizing the blockchain computation and storage, this project does not store the content, rather the IPFS hash where the encrypted content can be found. The modest goal of this project is to enable textual data to be encrypted with AES, using a shared key that is known to all the 'sharees'. The shared key is encrypted with the Ethereum public key of each sharee, while being stored in the IPFS document. The blockchain is used to manage the data sharing requests and storage of the public keys, as well as the IPFS location of the shared data.

QUESTION
I am developing a game (iOS/Android with Unity Game Engine) that requires to download resources to be stored locally on device. I wish to check free space on device to send an error message before download starts in case it's not enough.
How can I check it? I couldn't find any clear procedure on my research.
...ANSWER
Answered 2022-Apr-16 at 14:01It varies by platform so isn’t a simple answer. The free Unity plugin Simple Disk Utils handles it for you on Windows, Mac, Android and iOS and full source code is available on GitHub so you can see for yourself how it’s achieved on the different platforms.

QUESTION
In our CS course, we haven't covered how to analyse space complexity. We have though, been given the task of implementing an $\Theta(n)-time$ algorithm for reversing a singly linked list, with a maximum $O(1)-space$ (besides the actual array).
This is my implementation in Python:
...ANSWER
Answered 2022-Mar-15 at 21:53To analyze space complexity, you are analyzing whether the amount of memory is dependent on n. In other words, as your algorithm input size changes, number of nodes for the LL in this case, does that affect the space used?
In this case, by using recursion, you are adding frames to the call stack and using memory that way. Since you mention that you make a recursive call per node, can you reason the space complexity? How does that relate to your entries?
In this case, you won't return until next
is none
, at that point how many stack frames would be added to the call stack?
In this case, n frames would be put on the call stack, therefore you would get a Space complexity of O(n)

I have a folder in the: -> storage/app/ and I need to make a symbolic link.
Since the php artisan storage:link
links -> storage/app/public with -> public/storage.
What would be the best aproach to create a symbolic link for a folder that is not in the storage/app/public?
Or I always need to save images in the storage/app/public?
...ANSWER
Answered 2022-Feb-17 at 13:32You can make symlinks manually aswell. You could use midnight commander or linux command for that. You can open midnight commander with the command mc
, and you can make symlink with the linux command ln
(see: https://linuxize.com/post/how-to-create-symbolic-links-in-linux-using-the-ln-command/)

QUESTION
I am attempting to update my git repo by doing "git add ." within Visual Studio Code on my MAC. I have done this many times without issues but this time it is giving me this error "error: file write error: No space left on device" and "error: unable to create temporary file: No space left on device." Also when trying to clone another repo onto my device from github it says "fatal: could not create work tree dir 'cs1550-project1-domm2': No space left on device" I have 12.96gb left of 256gb. I do not know how I am out of space or how to free it. I just need to update my github repo for class.
This is running df -h within the VS terminal:
...ANSWER
Answered 2022-Feb-15 at 08:35It depends on where you are trying to do the git add .
As mentioned here:
The /snap mounts come from using software packages installed with Snap.
These utilize loop devices and are usually not writable.
You will get some sort of "No space on device" error when trying to write to any of these locations and that is represented in
df -h
as showing those mounts as 100% in use.
But in your case, assuming the repository is in /dev/...

QUESTION
I recently upgraded my MacBook Pro OS to Monterey and the Box folder/link which was formerly located in my home directory appears to have vanished. I can still see the Box folder as a "Location" in Finder and access files, but I can not use the Terminal/CLI to easily copy files to Box without using the Folder (which is annoying). With OneDive, GoogleDrive, Dropbox the links still exist - just not Box. Moreover, the "Get Info" button is useless, telling me the path to Box is "Box" although there is no /Box , /mnt/Box, /Volumes/Box etc...
Looking for a possible Path I can use has been frustrating, there is: /Users/$USER/Library/Application Support/Box but there is not a nice file system there I can use. /Applications/Box.app is just the application...
I'm assuming my cache of Box documents still exists locally as a FileSystem, but I have no idea where which I find infuriating.
Any information appreciated.
...ANSWER
Answered 2022-Feb-14 at 16:49Found it, path location is: /Users/$USER/Library/CloudStorage/Box-Box
Not sure how I missed this earlier or what happened to the link.
QUESTION
let's say I have blob structure like this:
dir0
├── dir1
│ ├── file11
│ └── file12
├── dir2
└── dir3
After listing the dir1
that contains two files file11
, file12
with listBlobsByHierarchy("dir0/dir1/")
method I'm getting two blobs with blobName
property set to dir0/dir1/file11
and dir0/dir1/file12
, so /
. That's OK, but in some point I need to get the
part.
My question is: Does Azure Storage SDK 12 for Java provides a mechanism for obtaining part from blob name? I could do it myself but it's hard to believe that SDK doesn't provide this functionality... Maybe you guys know different elegant way to do so? How do you usually handle such things?
It's a bit weird to me that SDK seems not to support building prefixes or getting file names from blob names :P I expected sth like fileName
field in BlobItem
class or buildPrefix(List segments)
method for joining path segments with '/'.

QUESTION
I have been working to fetch file path from storage till now, For example file path is /storage/emulated/0/Download/NTL_ANDRODI_DOGMA_SYSTEMS_SRL_A_SOCIO_UNICO_TEST NEW.afgclic
After android 11 its unable to fetch FilePath. After giving permission
uses-permission android:name="android.permission.MANAGE_EXTERNAL_STORAGE"
Its allowing for Android 11 also, but app is getting rejected by Play store. Since the permission cannot be used without a specific reason and its allowed only for filemanager or antivirus app. Now the point is how other app manages to work on Android 11 for fetching files.
I have been using READ and WRITE storage permission to access file from external storage. Files are required to verify license from other library information
Waiting to get the issue resolved. Thanks for the help.
...ANSWER
Answered 2022-Jan-24 at 05:56The android 11 introduced scoped storage to handle storage. Refer to https://developer.android.com/about/versions/11/privacy/storage for reference.
