I've noticed Ansarallah blurs out the surrounding terrain whenever they post missile launch videos, but most of the time it looks like totally nondescript hills and vegetation. Would it really be possible to figure out the location of these launches if they weren't blurred? And if so, does the blurring actually help if you can still get a vague outline of the horizon like in this one?

nah, this is just the appetizer to a big bowl of pasta made out of antimatter.

no siree no violence here in our violence system made out of violence, racism, and racist violence

For the love of god someone please edit this speech to footage of True Promises II and III: https://www.youtube.com/watch?v=56vtZsQgAF0

Once again, thank you so much comrade, I appreciate it!

this is looking like some Escape from Dannemora shit lmao

hope these guys who escaped are safe out there, how likely is it they never get caught?

You're very welcome! I'm slowly teaching myself what is essentially a mathematics undergrad degree, and I'm familiar with the book you're using, so if you ever have any other questions feel free to ask!

Word of advice: In most math books, especially at lower levels, the majority of the exercises will nearly always be some sort of direct application of the theorems and proofs in the preceding chapter of instruction.

So when you feel stuck, you should go back to those theorems and try to make sure you really understand what the proof is saying. Like try to be skeptical about the statements and examine them until you are fully convinced that the proof is ironclad. Then it'll be much easier to spot which theorems each exercise is meant to provide elaboration/nuance on, especially the earlier exercises in a chapter.

The later exercises in a chapter tend to be much more difficult, but you'll nearly always be able to prove them with the theorems you've already learned, it's just that the harder ones will be essentially foreshadowing theorems in future chapters. So the longer you stick with this, deeply examining every theorem and attempting every exercise, the easier it becomes as you begin to understand the pedagogical intent of the author.

The "go outside and touch grass with friends and family on new years instead of being on hexbear" struggle session we had a few years ago really sucked

Take a closer look at the proof and conditions of conjecture 2 in chapter 1. It states that if you have a positive integer n that isn't prime (i.e it is n=ab for positive integers a and b both less than n, then the integer given by (2^{n)-1 = (2}ab) - 1 is not prime either.

But the proof itself for that conjecture gives you a means of computing integer factors x and y of any such number where n is not prime. It uses the telescoping property of sums to prove in general under these conditions that:

(2^{n) - 1 = ( (2}b) -1 ) * y

That is, one of the two factors you are looking for takes the form x = (2^b) - 1.

So let's use this to solve part (a) as an example. (2^15) -1 = 32767 is not prime according to conjecture 2 because 15=3*5, a product of positive integers less than n=15 . Now plug it into the equation with a = 3 and b = 5:

( ( 2^{3*5 ) - 1 ) = ( (2}5) - 1 ) * y

Now you just solve for y:

y = ( ( 2^{3*5 ) - 1 ) / ( ( 2}5 )- 1 ) = 1057

And we already had x = (2^5) -1 = 31

We may now easily confirm the result by multiplying: 1057 * 31 = 32767.

To apply this to part b, all that remains is to repeat the process with a = 31 and b = 1057.

Ok, we started with not voting makes you as bad as the literal fascists.

Now we're at voting doesn't materially effect the outcome in the vast majority of cases, but you're still as bad as the fascists for not participating in the American civil religion by personally legitimizing our deeply undemocratic institutions with a vote that is essentially an endorsement of further neoliberal policy that would gladly see many of us dead or enslaved.

Is politics just like a sports thing to you or something? Where you show up to support your team every couple years? Why should I care if the Democrats or Republicans are in office if they are both committing genocide, if they both support policy that is a direct threat to the lives and livelihoods of myself and people I care about? I don't want to be complicit in that, but apparently I'm as bad as the fascists for not voting for actual fascists in sham elections?

Voter opinion doesn't correlate to policy in literally any study I've ever seen of the electorate in this genocidal farce of a settler-slaver colony. The problem is very clearly not a lack of voter participation, but a lack of actual, functioning democratic institutions. You're never gonna vote your way out of this situation because the capitalists built the entire system to prevent you from doing exactly that.

When you make a big show of voting blue no matter what, you tell the Democrats they don't need to worry about your interests because they have your vote regardless. Why the fuck would you do that?

Bump!

I had that happen to me a couple times on freebase DXM but never on HBr. Was it a large dose, high plateau trip?

It's true! I did this one a few years ago after hearing about it on Hexbear

Got it! Thanks so much comrade, that's extremely helpful! I genuinely can't wait until I find some work so I can come back here and pay forward all the aid I've received from my beloved online commie friends.

Bump!

Thanks for the bump, comrade!

ty for the bump, comrade!

ty for the bump!

Bump!
