Is anyone planning on upgrading a GPU?
Real IP
Been rocking a strix gtx960 for a while now. Used to think that maybe I could upgrade to a previous gen card or something after a while in hopes of cheaper prices, but afaik in the current market that isn't really a possibility. Though there wouldn't be any real point to it anyways, since I don't play any of the newest games and render times aren't ridiculously long. Top of the line stuff from a decade ago will do just fine for years to come so why upgrade?
Real IP
No, I couldn't afford one even before the current prices. t. intel integrated graphics
Real IP
>>57 But people said the prices have dropped. >>56 I'm more concerned about power consumption. The newer the card, the worse it gets. Currently I have rx570 and on dual monitor setup cpu fans never turn off, because it always keeps memory clocks at max. Why can't they invest in power efficiency rather than fps...

Usernames in Signal Jānis 08/30/2022 (Tue) 21:07:09 No. 40 Reply

>Our new method is faster and more efficient. It lays the groundwork for the introduction of usernames and phone number privacy which will offer new privacy controls around your phone number’s visibility on Signal. >Signal uses enclaves for contact discovery. Enclaves isolate data and its processing from everything else going on in a given server, obfuscating it even from server owners/administrators. This means that neither Signal nor the people who run the servers we rely on have access to or knowledge about what’s happening in an enclave. Our use of enclaves allows users to connect via their contacts while preventing Signal’s server owners from extracting the contact lists. >Encrypted RAM is a start, but it doesn’t do the full job. Simply knowing how memory is accessed can be enough to leak information. So, when we use enclaves, we build additional protections to defend against information leakage. We use “oblivious RAM” algorithms which work to obscure memory patterns and obfuscate data in enclaves. >Path ORAM has allowed us to speed up our processing for contact discovery. >In order to support phone number privacy, we need to expand the contact discovery database. Therefore, we will have more data to search for every query. The bigger the dataset, the faster we have to search in order to keep the user experience smooth. >Right now, the implementation of Path ORAM is the backbone for a new era of contact discovery in Signal, one that will let users choose usernames that they could opt to share with people instead of their phone numbers. Usernames have been one of the most requested features throughout Signal’s existence. Making usernames and phone number privacy a reality in Signal is a massive technical undertaking. It’s something we’ve been working on for a long time and will continue to work on for several more months or longer before it’s ready. Implementing Path ORAM for contact discovery is one step on that road, and we’re happy to share this inside look at the foundation we’re laying. I hope these cunts don't keep the phone number requirement, this is all trust based after all, and it would be convenient given certain CIA connections. TL;DR They improved the encryption/obfuscation algorithms speed enough to support a larger database, which they would have to deal with for usernames. https://signal.org/blog/building-faster-oram/

>I also remember(maybe it was matrix client) On the official Matrix yes >Also i don't get why signal needs built-in donation system and shitty coin when it gets funded by US gov. They don't usually get funded and its running of a fund the rich owner put upfront. >Why would it do something pain in the ass(not backdooring it in the first place) when it could just sell the product "e2ee open sauce IM" and have a little door open for NSA to walk to. The feds are iffy, sometimes they do genuine help for security, sometimes they harm things. In this case considering every phone can be cracked by pegasus, cracking Signal is unnecessary. Thats the backdoor, that applies to anything on a phone and most desktops. The app is doing nothing wrong as far as anyone can tell with the core security. None of this government funding and such changes the algorithm having reliable e2ee on just about everything, while telegram has none. They couldn't get much information if they wanted, and if feds wanted they'd just hack the phone. Again, a weird reason when Telegram has none and gives up info to authorities. https://tech.co/news/telegram-exposed-user-data

Signal announced her new role Monday at an event in Berlin. Literally just donations. Also Durov did VK and works with the WEF. His stance is against censorship, not privacy or security.

Impractical but pretty cool! >Although air-gap computers have no wireless connectivity, we show that attackers can use the SATA cable as a wireless antenna to transfer radio signals at the 6 GHz frequency band. >The results show that attackers can use the SATA cable to transfer a brief amount of sensitive information from highly secured, air-gap computers wirelessly to a nearby receiver. Furthermore, we show that the attack can operate from user mode, is effective even from inside a Virtual Machine (VM), and can successfully work with other running workloads in the background. Finally, we discuss defense and mitigation techniques for this new air-gap attack. https://yewtu.be/watch?v=rlmP-csuFIo https://arxiv.org/abs/2207.07413
