I think since a vector has a direction, he’s suggesting that the direction of the vector is pointed “the wrong way” with respect to time


What is the difference in meaning between:

  A: "you've reversed the vectored direction of time in your claim" 
  B: "you've reversed the direction of time in your claim"


time has multiple vectors

downvote me if you will but you were the one claiming dinosaurs are birds


I'm not downvoting anything, just trying to figure out what you are trying to say. Can you give names to the multiple vectors of time?


The scientific consensus is that while there are significantly many dimensions to the time space continuum, time makes is only one of those dimensions. Whether or not it is a strictly unidirectional component may be under some debate, but even in quantum mechanics and hypotheses like string theory, there aren’t multiple vectors to time, as it has only one axis and no start or end (that we know of). A vector necessarily has a start, end, and direction.


In Elizabethan England, didn’t a lot of women wear lead based makeup? I’d be interested in seeing how that affected crime rates or other metrics, if that data were available.

I learned recently that when elephants are very hot, they need to wildly flap their ears to cool their blood (as the blood flows from the body to the brain by way of the ears.) Maybe they hypothesized a similar effect?


It seems like you get a lot of your feeling of meaning and contentedness from social interaction. From what you’re saying about how travel, projects, etc don’t seem as fulfilling anymore, it really seems to me like you have some depressive tendencies.

I’m not a doctor, but just as a friend, I think you should really try to think of dealing with that existential sadness as a priority - not as an annoyance. Spending real time and energy towards improving your mental health could have real impact on every other aspect of your life.


2 books I recently read that point to social connection as essential to meaning and well-being are Lost Connections: Uncovering the Real Causes of Depression – and the Unexpected Solutions by Johann Hari, and Tribe: On Homecoming and Belonging by Sebastian Junger.


Do you have any recommendations for dealing with 'existential sadness', as you put it?


Seconded! This post sounds a lot like me a while ago, and depression was definitely a factor.


It says that the snails retracted only briefly as a baseline, but learned to retract for longer periods of time to avoid the jarring electrical stimuli. I’m totally unfamiliar with this stuff, but it seems to me that injecting a snail with RNA would also be a jarring stimulus. Therefore, wouldn’t it be learning from the injection itself to remain in its shell for longer at a sign of human touch?


They injected the other snails with control RNA from snails which were not subject to the shocks. In other words, they did control for this.


Came back here to say this. The relevant part: “Control snails that received injections of RNA from snails that had not received shocks did not withdraw their siphons for as long.”


I missed that - thank you for clearing this up!


may be the control injection doesn't hurt as much as the rna injection?


Control was also RNA, but from unschocked snail.


When dealing with burnout, you should identify what specific stressers exist for you in relation to programming, and then work to cut those stressers out from the process. I’m afraid that from person to person, programming burnout can come from different sources, so we’ll need more information first. For instance, is it specific aspects of the job / management? Is it the codebase itself, or a specific project you’re working on?


Going into the microservice aspect above, it provides a nice abstraction of remote function calls, so that you can write microservice code that looks like it's executing a local function, but is really just expecting a remote server to implement the method name. In general, that's just RPC calls though. Google's implementation has proven very intuitive to learn, and has a nice size community online for help debugging, etc.


See section 4.3 in the Spectre paper - https://spectreattack.com/spectre.pdf

It includes an implementation of the exploit in a few lines of javascript.
