  • FFMPEG Assembly Language Lessons

    Jump

  • maybe don’t just assume all of us knows what ‘GPR’ is. For those maybe wondering, it stands for “General Purpose Registers”.

    That is stated in lesson 1. It's in the first sentence that mentions "GPR" and in the heading directly above it.

    (By the way, I'm not the author.)

  • Are there any non-unixlike Linux-based OSes other than Android?

  • Couldn't we implement a non-unixlike userland though

    That's called systemd. :P

  • TIL: There is a website called WhoIsInSpace.com that sleekly catalogs who is in space, the spacecraft that brought them up, when they launched, and how long each have been in space for.

  • non-unixlike

    Linux-based

    Sorry, friend, but you'll have to pick one. Linux is Unix-like.

  • Linus responds to Hellwig - "the pull request you objected to DID NOT TOUCH THE DMA LAYER AT ALL... if you as a maintainer feel that you control who or what can use your code, YOU ARE WRONG."

    Jump

  • More like, "don't pick an inflammatory minor excerpt to represent a lengthy and well-reasoned post."

    Similarly, don't choose a red fruit to represent a pine forest just because there happens to be an apple tree somewhere within. It's misleading.

  • I wish this was given a less provocative title. People who read the whole post will find that it's not all shouting, and Linus' stance seems pretty even-keeled.

  • What kind of monster not only posts text as a screen shot, but re-posts a Lemmy comment as a screen shot... on Lemmy?

    Edit: I see they edited the post to include the text of the comment. I guess they must have noticed mine. :)

  • Why Is a Government Contractor Trying to Buy iPhone Hacking Tech From Us?

  • Audiologists raise concern over headphone use in young people

    Jump

  • It also seems that the headline currently on the article is different and switches out

    Both are present in the article; they don't switch out. One is the title (as you can see in the title bar of a desktop web browser) and the other is the top-level heading of the text.

    Looks like Lemmy picked up the former, which makes sense considering the document structure. BBC probably should have used the same phrase in both places.

  • How?

  • Danes launch bid to 'buy California' after Trump's Greenland threats

  • Isn't California's GDP about ten times that of Denmark?

    I guess that purchase would be quite a bargain.

  • Time to get serious with E2E encrypted messaging

    Jump

  • Indeed. Tucked away in a corner of their web site, where it isn't easy to find unless someone else guides you to it, below a large bold warning that discourages people from actually using it:

    Danger zone

    Advanced users with special needs can download the Signal APK directly. Most users should not do this under normal circumstances.

    This ensures that nearly nobody uses that build. Consequently, almost all chats on Signal will have an app store build running on at least one endpoint.

  • Time to get serious with E2E encrypted messaging

    Jump

  • It's not false.

    Signal's default, well-supported installations use Google services, so unless you're an extremely atypical user, those services are present on most of your contacts' devices. You might have the knowledge, skill, and motivation to remove those services from your own device, but since they're still present at the other end of most chats, you haven't escaped them.

    Let's also remember that E2EE doesn't protect the endpionts, and that Google Play Services run with system-level privileges.

  • Linus Torvalds to Hector Martin: 'Maybe the problem is you'

    Jump

  • Claburn's article seems biased toward Martin's position in the disagreement, using the most forgiving language possible for his behavior while describing the opposing side with obviously critical language and insufficiently covering the reasons for it. Linus's response might be mildly interesting, but the article is disappointingly poor journalism.

  • It’s been recently added to FDroid.

    No, it has not. A third party published it in an f-droid compatible repository. That might be convenient for someone who happens to trust that third party and manually add it to their F-Droid client, but it is not at all like it being added it to F-Droid.

    You can use NTFY with Molly (which has been on FDroid for some time).

    This does not refute what I wrote. Unless you only communicate with people who get their Signal app from some non-Google source and they all rig up alternative push notification channels, or every one of them uses Signal exclusively on iOS, your conversations are still tied to Google. Perhaps you have so few contacts that you could achieve that, but most people are not in that position.

    network-level metadata monitoring by anyone with sufficient access/influence at Signal or their data center provider (such as a government who doesn’t like encrypted messaging).

    This one is just a straight-up lie. Everything on the server is encrypted and no one has the keys except the participants.

    Encryption doesn't hide network traffic. Signal's centralised design means there is a single point where that traffic can be monitored and traced to reveal which endpoints are talking to each other, and where, and when.

    What I wrote is not a lie, which you would know if you actually understood these issues. Please stop making baseless accusations. You are wrong, and you are being very rude.

    If you're interested in correcting your ignorance, I suggest starting with this paper, which touches on some of the issues:

    https://www.ndss-symposium.org/ndss-paper/improving-signals-sealed-sender/

    If the paper is too much for you, the linked video does a pretty good job of explaining.

  • Thankfully, it's not that simple.

    A centralised service is an easy target for a government. (This is where Signal stands.) A decentralised one is significantly harder, because the government would have to be constantly discovering and processing every node in the network as new ones appear. (This is where Matrix stands, although it doesn't have many public servers yet.) Fully peer-to-peer decentralisation makes it harder still, because there are as many nodes as there are users, with network addresses that often change. (Some of these exist today, but are mostly experimental with few users. Matrix has done some proof-of-concept work in this area as well.)

    On top of decentralisation, tunnels like VPN and Tor can be helpful in avoiding ISP-imposed blocks.

  • There are a few messaging systems that don't rely on internet service. That usually means a peer-to-peer design using some form of radio link, which can work well for local gatherings (like protests), but these tend to be impractical for general use.
