ContactDiscoveryService VS Element

Signal uses SGX for remote attestation, which presumably lets the client verify that the code running on the server is a build of the OSS code and not a modified version. But I don't know the details or if this is reliable.

SGX and remote attestation described here:

Signal does private contact discovery and the effort they've gone to to do this is quite impressive.

TEEs have numerous privacy-enhancing applications that may benefit users. One of them is, as discussed earlier, private contact discovery; the Signal application uses a contact discovery service enhanced using Intel SGX, a TEE technology, to protect its users' privacy. A similar application of TEEs is performing malware analysis in a remote cloud service, so that the service may not identify users by the contents of their devices, such as the applications they have installed, especially important as 98.93% of users may be uniquely identified by the list of applications they have installed.

Signal (or, more accurately, one of its predecessors) used to use client-side private set intersection for contact discovery, but this scales poorly [1].

Now they use a solution based on Intel SGX and server-side trusted computing [2].

I made an account in Cinny using my Github account. I am trying to migrate my account into element.io. How do I do this? Forgot password is not even an option in Cinny.

Element is an open-source instant messaging client built on the Matrix protocol, offering users features such as end-to-end encryption, file sharing, and voice/video calls. The self-hosted version accommodates up to 200 users at no charge, providing a budget-saving secure and collaborative communication platform. perthguppy describes it as a "slack style team chat."

Hello! I am offering my services as a C and C++ tutor/teacher for $25 an hour. You pay at the end of each hour and you can walk away without paying for the first hour if you are unsatisfied. I can work with beginners through the upper intermediate level. I can either tutor you while you take an existing course or teach you from scratch. As for my experience, I've been working with C++ for over three years, driven by my love of learning, programming, and technology. I’ve worked with over 50 clients during the past year with all positive feedback. Below is my policy when dealing with less familiar subjects. While C and C++ are the languages I am most experienced with, I regularly take on jobs in other languages. When working with subjects I am not overly or at all familiar with, I only charge $20 an hour, sometimes with additional discounts. This is to compensate for the extra time I may need to spend on the project. I am a quick learner who can learn what I need to help you through your course as you go. I have done this with many people before with great results. Please note this works best the closer you are to the start of your course. The following are subjects I have tutored for at least one semester: C, C++, Python, OpenGL, operating systems, drivers, R, and Web Assembly. I addition, I have some limited experience in the following subjects: HTML, CSS, JavaScript, Lua, Bash, Vulkan, CMake, NASM, Pandas, and Asio. Again, please keep in mind that even if your subject is not listed, I may still be able to help you. Please DM me if you are interested in hiring me or have any questions at all. We will work via Element (https://element.io) voice/screen share calls, so please make sure you have a mic available. I look forward to hearing from you.
