  • Hi! Although your post is full of reasonable advice on maintaining privacy online I want to challenge you on the statement that the threat model matters. The contrapositive of the statement “I don’t need privacy if I have nothing to hide” is “I have something to hide, if I need privacy”. This puts those marginalized groups you mentioned in a position where simply by using a privacy tool or technique, they draw suspicion to themselves. It might immediately raise subconscious alarms in internet communities like facebook, where the expectation is that you use your real name.

    The only way privacy measures work for anyone, is if they’re implemented for everyone.

    Further, I’d like to challenge the concept that a cis white tech bro has nothing to hide. There’s a big invisible “for now” at the end of that statement. The internet, mostly, never forgets. We’ve had waves of comedians get “cancelled” over tweets they made years ago. Times change, people grow, laws regress. Posting statements about abortions is as of this year, suddenly unsafe. Maybe posting about neurodivergence comes next. Who knows with the way the world is going, maybe 5 years from now you’ll regret having posts on /c/atheism associated with you.

    I think a good way to be considerate of privacy is to think in terms of identities, what those identities are for, and what links those identities. Does your identity on github need make comments about your political leanings? Should your resume have a link to your github? Does your identity on etsy need to have a link to your onlyfans? Does your dating profile need a link to your reddit account? Your “2nd” reddit account? Not all of these are clear yes or no answers, they’re just things to consider and make decisions about. Also, consider what class identities you only have one of, and what class of identities are for the most part unchangeable, e.g. attaching your phone number to two separate identities functionally links them.









  • … but there is a way, and it has been proven.

    One of the more memorable physics classes I’ve had went into the history of discoveries that led to our understanding of relativity. The relevant story here, starts with how sound travels though air.

    Let’s say you’re standing at the bottom of a building shouting to your friend peeking out a window on the 5th floor. On a calm day, that friend will hear you at pretty much the same time as someone standing the same distance away, but on the street. However, if it’s windy, the wind pushes around the air through which the sound of your voice is traveling, the friend up in the window will have a slight delay in receiving that sound. This can of course be verified with more scientific rigor, like a sound sent in two perpendicular directions activating a light.

    Scientist at the time thought that light, like sound, must travel though some medium, and they called this theoretical medium the Aether. Since this medium is not locked to Earth, they figured they must be capable of detecting movement of this medium, an Aether wind, if you will. If somehow the movement of this medium caused the speed of light in one direction to be faster than another due to the movement of this medium, measuring the speed in two directions perpendicular to each other would reveal that difference. After a series of experiments of increasing distances and measurement sensitivities (think mirrors on mountain tops to measure the time for a laser beam to reflect), no change in the speed of light based on direction was found.

    Please enjoy this wikipedia hole: https://en.m.wikipedia.org/wiki/Michelson–Morley_experiment , and please consider a bit of caution before you refer to things as facts in the future!



  • I do this with my xreal glasses sometimes when washing dishes or whatever. Connected to phone in my pocket with a desktop mode, set a black wallpaper, and drag the video into a corner.

    It’s nice for situations like that, where you’re doing something with your hands and can’t reasonably place a screen in a way where you wouldn’t have to constantly strain your neck to look at it.
