Hi,
A little question for the devs of CoMaps. Is a build for Linux (.appimage) is planned ? 🙏
Thanks.
I'm open to all solutions :) But it there some ready Bluetooth remote pilot existing ?

Hi,
I'm using (like a lot of us, I presume ) Mozilla MDN
But I just discover that they display advertise :'(\ !
Damn that think (MDN doc) is run by committer (I did post few thing on it) and they display advertise ! f**king hell ! Can I have my cut 💵 then ?
beside jokes, do you know good (decentralized ?) alternative to mdn docs ?\ Thanks.
Hi,
I've discover haml and pug [^1] ( both web template engine )
It's totally Pytonic ! ( and make even more sense to use it with python rather than JS 🤮 )
I've look, if it exist for Python, but so far, I've found only
The first, only convert pug into another template :/ \
The second, didn't pass the alpha version. \
The third, require dependence, not maintained etc.. \
So I didn't found a Python package that could do haml/pug to html directly, without too much dependence...
For example:
From
pug html head title Example for Python discuss body h1 Hello world p This is a paragraph.
To
html <html> <head> <title>Example for Python discuss</title> </head> <body> <h1>Hello world</h1> <p>This is a paragraph.</p> </body> </html>
Do you know if such thing exist ? \ If not, I will build my own (FLOSS). ( I'm open to any advice to do so :) )
Thanks
[^1]:Pug is a template engine heavily influenced by Haml and implemented with JavaScript 🤮 for Node.js

Hi,
I'm following my previous post \ How encrypt email with a GnuPG public key ? [ solved ]
So I managed to encrypt the email body with GnuPG public key.. But I don't figure how I can do the same for the title ?! \ ThunderBird manage it.. any idea how ? \ asked on Official Thunderbird forum
Thanks.
I finally manage to encrypt the body trough ptyhon-gnupg ( warning their documentation is still in alpha stage. )
now, remain to encrypt the subject (ThunderBird compatible) if you have any clues I'm all ears
When time permit I will publish my code in a pastbin.
Wubba Lubba dub-dub**
indeed, but a lot of Linux distribution come with it :)
otherwise it's installable.
instead of using a library I can directly use subprocess with gnupg but in both case it seem gnupg require to import the public key to the keyring !? I don't want that.
Hi,
I'm already using
python from smtplib import SMTP_SSL from email.message import EmailMessage
To send emails.
Now I would like to be able to encrypt them with the public key of the recipient. ( PublicKey.asc )
an A.I provide me this
```python import smtplib from email.message import EmailMessage from cryptography.hazmat.primitives.asymmetric import ec from cryptography.hazmat.primitives import serialization from cryptography.hazmat.primitives.ciphers.aead import AESGCM
Load the ECC public key from the .asc file
with open('recipient_public_key.asc', 'rb') as key_file: public_key_bytes = key_file.read() public_key = ec.EllipticCurvePublicKey.from_public_bytes( ec.SECP384R1(), public_key_bytes )
Create the email message
msg = EmailMessage() msg.set_content('This is the encrypted email.') msg['Subject'] = 'Encrypted Email' msg['From'] = 'you@example.com' msg['To'] = 'recipient@example.com'
Encrypt the email message using the ECC public key
nonce = bytes.fromhex('000102030405060708090a0b0c0d0e0f') cipher = AESGCM(public_key.public_key().secret_key_bytes) ciphertext = cipher.encrypt(nonce, msg.as_bytes(), None)
Send the encrypted email
server = smtplib.SMTP('smtp.example.com') server.send_message(msg, from_addr='you@example.com', to_addr='recipient@example.com') server.quit()
Save the encrypted email to a file
with open('encrypted_email.bin', 'wb') as f: f.write(ciphertext)
```
I like the approach, only one "low level" import cryptography
but the code seem wrong.
if the body has been encrypted as ciphertext I don't see this one included while sending the email.
How are you doing it ? or do you have good tutorial, documentations ? because I found nothing "pure and simple" meaning not with of unnecessary stuff.
Thanks.
I might found a workaround IPFS + OpenTimestamps

Hi,
I'm looking for a solution to archive files in a decentralized system. that would meet those requirement:
I was considering IPFS but it does not date-stamp the upload :'( you can make a description-file but this is unreliable, as you can set any date..
I'm lost between hyphanet.org and Freenet.org ?!\ are those the same project ?
According to A.I: > Hyphanet is focused on secure, private, and efficient communication and data sharing, with an emphasis on enabling users to monetize their data while maintaining control over their data sovereignty.
is that true ? I can't found the information on their website...
Thanks all for your input !
So yes /sdcard was /storage/emulated/0 and it's a real sd-card.
That was indeed formatted as FAT, I reformatted into EXT4 (from a desktop Linux)
put the SD-card back into the phone and started the phone.
Ive tried (in the phone)
su
chmod 777 /storage/emulated/0 #yes it's still mounted as emulated !
stat /storage/emulated/0
#...
#Access: (0771)
#....
So I'm still blocked... any ideas ?
Thanks.
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.
```bash 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 ?
I've found the most simple way (for my case)
adb shell 'a command'
example
adb shell ls /
Thank you all for your input.. but it seem my question is still not fully answered...
let me rephrase, I'm not looking to have a GUI to transfer files, but I would like to execute terminal command remotely (from my computer) to my android phone. Like SSH .
So I've read that I can install a SSH server on my android phone.. (If you know some's (FLOSS), I'm all ears)
Or if you know a better way than SSH I'm all ears too.
Thanks.
I've found
#container > div:not(div.barfoo)
seem to do the trick..
Hi everyone,
I have something like this
```html <div id="container">
<div> <div class="foobar"></div> </div>
<div> <div class="foobar"></div> </div>
<div> <div class="foobar"></div> <div class="barfoo"></div> </div>
<div> <div class="foobar"></div> </div>
<div> <div class="foobar"></div> </div>
<div> ```
I would like to select all the #container > div (the childs of container)
that do not have a div.barfoo in their childs.
is it possible with CSS ?
I'm at
css #container> div :not(div.barfoo) {}
but this is not working, and will select anyway #container > div > div
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,
Is there somewhere a list of all the changes made compared to Firefox ?
edit:
Sorry if it's been already asked over here, but it seem that Lemmy do not provide a search within a Community 😮
no, actually we can, there isn't a shortcut to make such a search. and no ability to limit the search to the titles.. !

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.

```nginx 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 }

} }
} ```
setfacl -m m:r aFile
#re set the mask
solve the problem, but the question is: why the F**** this is happening !?
Hi,
I got FileA that have 640
a getfacl FileA give me
```txt
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
bash chmod 600 aFile getfacl aFile
txt ... user:aUser:r-- #effective:--- ... mask::--- ...
Why suddenly aUser lost his ability to read the file !?!?!
Update, this is only happening when I copy files from a ~SMB share... :'(
Otherwise it's correct...
Hi,
I've set for a directory the following ```bash 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
txt
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
bash stat aFile.txt
return
txt (0777/-rwxrwxrwx) #!!!!
is that normal !!!!???
Thanks.
Proxmox seem powerfull
It's a Type1, not Type2
https://en.wikipedia.org/wiki/Hypervisor#Classification
Thank you all !
Indeed setting execute perm on example, sub1, sub2, static
The program/user have now access to the directory.
In order words all the parents directory need at least execute in order to have access in the targeted directory...
Now I gave 751 for static. Meaning than others (here nginx) cannot list the files within. But never the less it works
the static files are appearing when requested (HTTP) but forbidding nginx to list the directory is changing something ? (performance/security)
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
bash 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.
I wanted to have a default server that catch ~wrong DNS query to the server
Solution
I don't know how to link to my previous lemmy post, so here it is again
server {
listen 443 ssl;
server_name _;
ssl_certificate /etc/nginx/ssl/catchall.crt;
ssl_certificate_key /etc/nginx/ssl/catchall.key;
error_page 404 /404_CatchAll.html;
# Everything is a 404
location / {
return 404;
}
location /404_CatchAll.html {root /var/www/html/;}
}
The full working code:
server {
listen 443 ssl;
server_name _;
ssl_certificate /etc/nginx/ssl/catchall.crt;
ssl_certificate_key /etc/nginx/ssl/catchall.key;
error_page 404 /404_CatchAll.html;
# Everything is a 404
location / {
return 404;
}
location /404_CatchAll.html {root /var/www/html/;}
}
ok I've found something that ~works !
server {
listen 443 ssl;
server_name _;
ssl_certificate /etc/nginx/ssl/catchall.crt;
ssl_certificate_key /etc/nginx/ssl/catchall.key;
error_page 404 /404.html; #at /var/www/html/
location /404.html {internal;}
return 404;
}
so i get the default 404 html from nginx. but not the one that I specified error_page 404 /404.html;
any ideas ?
