thanks for that, i’ll definitely be using one of those in the future!

in this case though i was just lazily copying someone else’s link from that HN post because i thought people here might appreciate it.




This is a nice article but it’s a shame the author neglected to mention postmarketOS which is aiming for a 10 year life-cycle for smartphones by using a non-android Linux stack.


after watching this video from the same FDA campaign, I guess the answer is no? the condition we’re seeing here is supposed to be a metaphor or something?

i’m not a propaganda expert but it seems like telling obvious lies risks discrediting any truths their campaign might have.



When I saw this headline I couldn’t help but wonder if this might be related to that blackmail thing back in March… but sadly from how not-comprehensive it is, it clearly isn’t.

  • Only Turing (their microarchitecture introduced in late 2018) and newer GPUs will be supported by this open-source kernel driver, because it uses their new new “GPU System Processor (GSP)” architecture which involves loading binary firmware (which they aren’t opening the source for) on the GPU at runtime.

  • NVIDIA’s user-space libraries and OpenGL / Vulkan / OpenCL / CUDA drivers remain closed-source.

Having the kernel module be open source (and maybe one day accepted in mainline) will certainly make life easier for some people (especially nvidia engineers), but from the security, privacy, and philosophical standpoints, this doesn’t really change much.

so,

🖕 Nvidia

(still)


oh, interesting, i see they actually had their own package manager from 2005 to 2013!





it’s the network effect; if you know a bunch of people using OTR and you switch to something that doesn’t support it then you can’t talk to those people anymore.

When OTR support started going away (as a result of the campaign against it by the OMEMO guy) a lot of people stopped using XMPP rather than adopt one of the OMEMO clients that existed at the time. (In the pre-omemo days xmpp+otr was my primary means of daily communication; today I hardly ever use xmpp at all anymore. 😞)

I am pretty dissatisfied with all of the messaging solutions that are popular today, so I’m thinking about giving OMEMO another shot… but asking around I’m realizing that I actually still might know more OTR users than OMEMO users! (hence the question in this post.)


jackline and coyim are two XMPP+OTR clients that are actively maintained/developed, and last I checked there were still some others (plus numerous more that are not being maintained but are still widely used). it looks like the former is open to adding OMEMO while the latter is opposed to it.

in any case there are many people still using OTR on a daily basis; I know people that use separate accounts and clients to talk to their OTR and OMEMO contacts.


Is there any decent XMPP client that supports both OTR and OMEMO?

The OMEMO dev’s push to get many clients to drop OTR support has seriously fragmented the XMPP world :( …

What makes you think it was destroyed? It appears that packages were updated in both their stable (Debian bullseye-based) and oldstable (buster-based) releases just yesterday.

I wouldn’t say it’s exactly creative, but a common useful application of qrcodes is for communicating wifi network names and passwords. If you use a GNU/Linux distro with NetworkManager, wifi-qr is a nice tool which can not only scan but also generate these phone-compatible wifi qrcodes for any saved wifi network your computer knows about. On debian-based distros, just apt install wifi-qr and run the wifi-qr command and you’ll get a qr code right there in your terminal which you can scan with a phone.


Out of curiosity, when ICE agents show up at protests in the US and arrest people who will ultimately be deported, would you say that those people are also not being punished for attending a protest?




you’re looking for steganography; I’m not aware of any steganographic constructions involving qrcodes, but there could be some. generally speaking, stego becomes practical in settings where there is unimportant high-entropy data which can be replaced with an encoding of the (typically encrypted) hidden message without altering the “cover” message in a detectable way. it might seem like this is the case with qrcodes due to the error correction; if you change a few random parts of the qrcode, due to the error correction it might still decode properly. However, this is probably easily detectable if the adversary has a high-resolution image of a candidate “maybe stego” qrcode: if decoding and re-encoding it produces a different qrcode, that would indicate that there had been extra data hidden in the error correction. (or, using a more advanced decoder than the typical ones, they could also simply see what the error rate is.)


There are many types of QR code. iirc a single qrcode can contain up to a few kilobytes, but the more data you put in it the more difficult it will be to scan.

so, you could use qrcodes for offline distribution of short text messages or very low resolution images. I think mobile devices’ qrcode scanners will display the contents of TEXT type qrcodes, but they probably don’t have support for decoding an image from one (so such an app would need to be written). you can create TEXT type qrcodes using the qrencode tool (packaged in major linux distros) or using websites like https://www.qr-code-generator.com/ (note that I think only their URL and TEXT types are offline; the others upload a file to their servers and make a qrcode containing a URL for it).

This qrcode says “Hello”:

This qrcode contains this 88x26 pixel (1467 byte) image:

(created using cat lemmy.png |base64 |qrencode -o lemmy_qr.png; can be decoded using zbarimg lemmy_qr.png |sed 's/QR-Code://'|base64 -d > output.png. on debian/ubuntu you can apt install qrencode zbar-tools to get the two required commands.)


The article has a 3rd occurrence of the word “conscription” besides the two OP quoted:

Yulia Girdvilis, the head of the communication department of Kyiv police, said: “There were no arrests. There were police officers at the event who explained that during the martial law mass events are not allowed and people dispersed on their own. There were military commissars present at the event who had the authority to check men’s documents. Some of the men in their 30s were taken to the draft boards [conscription offices] for further investigations.”

From that description I’d say it is effectively a punishment for protesting, because if they hadn’t attended they probably wouldn’t have gotten caught evading the draft.


as far as i know you can’t yet; i recently posted this question about getting more activitypub interop.







the Tesla wikipedia article currently has better coverage of his “founder” status than last time I saw it; it used to just say “the company considers him a founder” but now makes clear that he was not initially involved but somehow won the right to call himself a founder in a lawsuit settlement with the actual founders.



so that i could see posts from those places on my lemmy front page, the same way i see lemmy posts from other instances. i guess there would need to be some mapping of reblogs+favourites to upvotes for the algorithms here, but that seems straightforward enough.


interop with other fediverse platforms

If I understand correctly, users of other fediverse things like Mastodon can follow lemmy communities (and users?) but the reverse is not currently possible. Would it not make sense for lemmy users to be able to subscribe to a hashtag or user on a mastodon instance?..
