Yesterday I installed Ubuntu 19.04, but all notifications don’t come. My notification list is empty always. On Manjaro with same version of Gnome notifications worked. I tried Thunderbird*, Evolution, Mailspring. *in Thunderbird notifications appear on the desktop. Even when I install any app, in my notifications list don’t be shown message about transaction is over. I’ve thought the issue is in gnome extensions. But disabling it didn’t help. Any ideas?

## [ Politics ] Open Question : Was Trump wrong for telling Congress Lawmakers to “go back to where they come from” or no?

Trump on Sunday morning targeted “progressive Democratic congresswomen,” — most likely referring to the “Squad” of freshman progressives which include New York Rep. Alexandria Ocasio-Cortez, Massachusetts Rep. Ayanna Pressley, Michigan Rep. Rashida Tlaib, and Minnesota Rep. Ilhan Omar — and told them to “go back” to their “corrupt” and “broken and crime infested” countries.

## Unity launch bar and menu bar won’t come up on Ubuntu 16.04

I have an old 32-bit netbook and have been running Ubuntu since 2012. I currently run Ubuntu 16.04 LTR and have run update manager consistently. When I logged in today, my wallpaper came up but without the launch bar and without the top menu bar. I have tried everything I know of, including some of the older suggestions on this site. Despite being a long-time Ubuntu user, I am not code-savvy. I use the Unity interface for everything. Can you help?

## How come Windows (or Linux) is seemingly Machine Independent?

How is it possible that I can, say, pop in a Windows installation DVD on any compatible computer, regardless of wether it is AMD or Intel and it’ll still boot? Can the BIOS select the assembly to run, or how is it written?

The whole process will just take a few moments.

## How to come up with NP Complete and NP hard problems?

So, from my understanding, NP-Complete is when there is no known algorithm to solve it. Lets take clique for example, it’s a known NP Complete problem with the info

clique

input: a undirected graph $$G$$ and a natural number $$k$$

question: Does $$G$$ have a clique of size $$k$$?

How do I make like a twist to this so that I know it’s still NP Complete?

## How come keys can stay secure through factorization of primes

Sooo I under n=pq where p and q are both large primes so it making factorizing them inefficient to the point of impossible but there must a a list of prime sets (heard people call them trap doors I think?) That are well know? Like if p and q are both know pairs wouldn’t you be able look at n and go well I know this already so I don’t need to even work it out I already can tell you it’s pq. Or are there an infinite number of primes available and Is it only limited by the how large the key is? Isn’t there a finite ammount of primes available in 2048 bits that it wouldn’t be that hard? Clearly it’s time consuming enough that it hasn’t been cracked but I don’t get why not since you know how many primes there are and also what they all are.
