Hi,

I would like to change the owner of a directory on the sdcard /sdcard/aDirectory

I have a terminal installed on my Android 10 (LineageOS 17) com.android.terminal

sudo is not present so I use su and it works.

su
#Terminal was granted Superuser rights

cd /sdcard
chown 10:10 aDirectory
#I don't get any error message.

stat aDirectory
#Uid (0/root)

So the owner stay root no matter what I'm doing, any ideas ?

Hi,

I created another user on my custom rom Android (aka Multiple users)

Unfortunately when doing so the system do not adapt the permission of the sdcard and some other directory, thus the new user can't access them :/

So I wanted to "remote" terminal into my android device from my computer.

How are you achieving this ? ( without 3thparty apps please ! )

Thanks.

Hi everyone,

I would like to enable Cross-Origin Resource Sharing on my Nginx server. for few origins (cors requestor)/domains.

I've found this article https://www.juannicolas.eu/how-to-set-up-nginx-cors-multiple-origins that is nice, but not complete and on my browser seem really hard to read due to the layout 🤮

So I've opened a CodeBerg git repository for the good soul that want to perfect this piece of code the allow the most of use to use CORS with Nginx.

https://codeberg.org/R1ckSanchez_C137/BestOfxxx/src/branch/main/Nginx/CORS_MultiDomains.py

If you don't want to create an account on codeberg feel free to post your code here !

server {
    # Server

    map "$http_origin" $cors { # map in Nginx is somewhat like a switch case in a programming language.
        default ''; #Seem to set $cors to '' empty string if none of the follwing rexeg match ?
        "~^https:\/\/([\w-_\.]+\.)?example.com$" "$http_origin";
            #regex domain match
            # ~ mean I suppose the string is RegEx ?
            # Need to come with a RegEx expression that match https://anything.example.com[optional ports and Query string ?X=Y]
        "~^https:\/\/([\w-_\.]+\.)?example2.com$" "$http_origin"; #regex domain match
        }
               

    location /static {
        
        # if preflight request, we will cache it
        if ($request_method = 'OPTIONS') {
            add_header 'Access-Control-Max-Age' 1728000; #20 days
            add_header 'Content-Type' 'text/plain charset=UTF-8';
            add_header 'Content-Length' 0;
            return 204; #https://developer.mozilla.org/en-US/docs/Web/HTTP/Status/204 }

        if ($cors != "") {
            add_header 'Access-Control-Allow-Origin' "$cors" always; # <-- Variable $cors
            add_header 'Access-Control-Allow-Credentials' 'true' always;
            add_header 'Access-Control-Allow-Methods' 'GET, POST, PUT, DELETE, OPTIONS' always;
            add_header 'Access-Control-Allow-Headers' 'Accept, Authorization, Cache-Control, Content-Type, DNT, If-Modified-Since, Keep-Alive, Origin, User-Agent, X-Requested-With' always;}

       # configuration lines...

    }
}

Hi,

I got FileA that have 640 a getfacl FileA give me

# file: FileA
# owner: me
# group: me
user::rw-
user:aUser:r--
group::r-x			#effective:r--
mask::r--
other::---

So it's give me the expected...

but when I do

chmod 600 aFile
getfacl aFile

...
user:aUser:r--		#effective:---
...
mask::---
...

Why suddenly aUser lost his ability to read the file !?!?!

Hi,

I've set for a directory the following

setfacl -dm u:aUser:r aDirectory
#set new files to be readable by aUser

cp ~/Desktop/aFile.txt /xx/xx/xx/aDirectory

getfacl aFile.txt #the copied one

# file: aFile.txt
# owner: me
# group: me
user::rwx
user:aUser:r--
group::r-x
mask::rwx
other::rwx

So indeed we see the aUser got r--

but

stat aFile.txt

return

(0777/-rwxrwxrwx) #!!!!

is that normal !!!!???

Thanks.

Hi,

I've noticed something quite odd, but I don't know if the problem come from Linux itself or nginx..

In order to grant nginx access to a directory let say your static see: https://stackoverflow.com/questions/16808813/nginx-serve-static-file-and-got-403-forbidden

These parent directories "/", "/root", "/root/downloads" should give the execute(x) permission to 'www-data' or 'nobody'. i.e.

but it seem not only the direct parent need to be given XX5 but all the chain

for example

example
└── sub1
    └── sub2
        └── static

it seem you need to set allow others to read and execute 5 all the parents example, sub1, sub2 Why is that !?? I've found it so akward and unsecure ! is there a workaround ?

Thanks.

Hi everyone,

I was wondering if you know a way to use the generated OpenPGP key created trough Thunderbird to sign PDF's ?

(Devuan distro)

Thanks.

Hi,

As CSS do not have a color-overlay[^1] filter.

There is some heavy work around:

https://isotropic.co/tool/hex-color-to-css-filter/

that use a combination of CSS filter to target the desired color...

Those online calculators are neat, but I would like an offline version, in case the provided one become inaccessible.

I've downloaded the zip of https://codepen.io/sosuke/pen/Pjoqqp

But it doesn't work locally.. :/

So I would like to know, if someone know one in 🐍 Python ? or how can I make one then ?

Or if someone know another way to have the color-overlay[^1] effect in html\css, I'm all ears !

Thank.

[^1]: To apply like in Photoshop a color on the shape of the image (so not on the parts that have transparency.

Hi,

Intro about XDA forum (skippable)

I was using a lot xda-developers.com for anything that was related to Android development and phone support. (ROM etc..)

But it became rotten -->

😱

😱

Current situation ton Install another ROM ~OS

As you may know, in order to install another ROM For example to get rid of Google ! 👿

You need one that is specifically build for your devices for example: https://wiki.lineageos.org/devices/

This is so inefficient !

You might have heard of Treble that focus on this problem

• https://android-developers.googleblog.com/2017/05/here-comes-treble-modular-base-for.html
• https://www.hsc.com/resources/blog/what-is-android-treble/

sadly it's made by google 👿 and I doubt that they will release all the code. We will see.

If you don't know what is AOSP <--

The question : How to install AOSP on a "Supported device"

I've always use only google-free smartphone ! But OMG it's time consuming.

1. Found a smartphone ( with the spec you want and in your budget )
2. Check if you can have\import it in your "country"
3. Check if someone already cook a ROM that support that specific model
4. or create it by yourself (even more time consuming )
5. Sometimes: bypass any protection that prevent to install another ROM !
6. Finally install the ROM's, boot loader etc...

At this time, when it seem that Treble is not there yet... Do you have a quicker path\Solution ?

Thanks

Hi everyone,

Before I was using SendEmail but it seem that it's not supporting TLSv1.3 :/ too bad because the SMTP server that I would like to use require it.

Do you have any solution ( Windows ) to send emails (TLSv1.3 supported) trough the CLI? Not powerShell ! but CMD
