Hi everyone. I have a Samsung S20 FE running LineageOS 23 (Android 16). I’d like to disable the Wireless Emergency Alerts service. The plan is to run:

adb shell
pm disable com.android.cellbroadcastreceiver.module

Questions:

Is it safe to disable this module this way?

Will the phone go into a bootloop after the next reboot?

Does anyone have verified information or real experience with this on the S20 FE / LineageOS 23 (a-16)?

Autoinstall ubuntu (programming.dev)
 

I want to automate the installation of ubuntu-desktop v24.04 hybrid.iso using autoinstall.yaml. I found that the steps for this are described here: https://danielpersson.dev/2023/08/07/looki-looki-no-hands-automatic-install-of-ubuntu-server/
https://youtu.be/DtXZ6BMaKbA

After making the necessary changes and repacking the ISO, I ran into a problem:

  • when flashing the image with balenaEtcher, it shows an error that the partition table is missing;
  • if I still write the new image to a USB stick, it doesn’t contain an MBR/GPT partition table and therefore won’t boot on a PC.

My question is: what am I doing wrong? Do I need to manually specify the partition table when repacking the ISO, or is the cause something else?

Thank you in advance)

@mouse@midwest.social, @ferric_carcinization@lemmy.ml, thank you for the help and the links — things are a bit clearer now.

As I understand it, SNI slicing helps obscure the presence of the SNI field in the TLS ClientHello by splitting it into two chunks. The idea, it seems, is to make it more difficult for third-party network filters or DPI systems to detect or extract the SNI reliably.

    Hi everyone,

    I came across the Firefox preference network.http.http3.sni-slicing, which appears to be related to HTTP/3 and SNI handling. However, I’ve found very little documentation explaining what it actually does.

    Could someone with knowledge of Firefox internals or HTTP/3 clarify:

    • What exactly does this setting change in the browser’s behavior?
    • Does it provide any privacy or security benefits?

    I’d appreciate any insights. Thanks!

    I was thinking along the same lines. At this point, I have:

    • Removed all URLs in about:config
    • Disabled browser updates
    • Disabled all telemetry settings I could find

    Despite all these actions, the browser still sends this request on startup. I'm starting to think it might be a setting that can't be changed via about:config.

    Hi everyone, When starting LibreWolf, I noticed that it sends the following DNS query:

    Standard query 0x053e A host
    Standard query response 0x053e A host SOA ns0.centralnic.net
    

    The query is for a non-existent domain host, and the response includes an SOA record from ns0.centralnic.net. I'm wondering why LibreWolf is making this request. Is it related to security features, DNS caching, connection checks, or something else?

    DNS is set manually, but this query still appears every time the browser launches.

    Any insights would be appreciated!
