Hello fedi!

I have an .MVAX #firmware #update file for an MV Silicon chip (unknown model).

Has someone already encountered those? And if yes, is there some documentation, tooling or existing #ReverseEngineering work done of that format?

For the record, the file magic (first 8 bytes) is as follow:
4D 56 B5 58 05 01 13 00

And the end of the file contains the following (no spaces, wrapping is mine):

MVSKeyFileMVBP10<0x90>0xBE>SIMPLEs
<0xD3><0x9A>.<0x90><0xD9>
MVSILICONKEYFL<0x00><0x00>
<0xFF><0xBD><0x00>0x00>

Thanks in advance for your help!!

You often see us reporting our RB status, and might wonder what's so important about #ReproducibleBuilds – want a recent example? Take a look at https://web.archive.org/web/20260402133949/https://github.com/Nekogram/Nekogram/issues/336 – and the POC at https://github.com/RomashkaTea/nekogram-proof-of-logging

In short: Release APK was built from different code, including a logger to catch all phone numbers contacted. Oh, and the dev thinks that's fine (https://t.me/NekoUpdates/531).

RB would have failed for that app, and shown the diff.

Stay safe out there!

Here's an interesting SEO hijacking repository on Github. You'd think they would switch accounts before replying to their own messages, but no.

If anyone is interested, there are probably a good amount of #malware samples in there!

i guess my point here is that reactionary behavior does not really benefit anyone and just leads to bad decisions

I am so proud @Paulatics is part of my government!! Thank you for talking about this huge issue! This is such an excellent speech, and I hope this makes some sort of difference (as I'm pulling my hair out trying to help write responses to Reflect Orbital's horrifying FCC proposal for space mirrors)

Also, this speech means that I'm officially recognized by the Canadian Senate as a goat farmer and orbital dynamics expert. That's right up there with having an asteroid named after me!

Since the NextCloud Office maintainers have not taken into account the arguments against their decision to use Microsoft OOXML as the default format, I submitted a pull request with code that sets OpenDocument as the default format:
https://github.com/nextcloud/richdocuments/pull/5516
I strongly encourage you to retweet, upvote, and comment on this PR, which will be harder to ignore than a “resolved” issue.

Edit: The maintainer (who is clearly terrible at managing comm) has closed the PR and directed people to the issue, which remains open for votes and comments↴
