I have been getting monitor tearing time to time, even with windows. It wasn't occurring often, and I could fix it by turning the monitor off and on, so I have been sleeping on it.

A few days ago, it began tearing like crazy, and it happens after turning the monitor on for a few minutes. It came to the point where the computer is nearly unusable, so I want to solve the issue once and for all.

How do I go with resolving a monitor tearing issue? Or, is it the faulty monitor? The issue also happens on Windows, after all..

I got this comment as a reply to my post:

You can get a job and do your math, too.
Other people do more with less, why can't you?
Answer:

Greed and entitlement.

I feel quite offended, that I have to care about someone else who "do more with less". What does it have to do with greed? I do not get the thought process behind it.

I wonder if I am overreacting. I would feel better if they just said to get a job, but it felt more like they are trying to make fun of me.

EDIT: Thanks everyone for thoughtful replies! Now I feel a lot better - I was in very bad mood when I got the reply above, so I felt even more attacked. Still, I should learn to not get overly offended like this.

I am in the field of applied math, and it took me 6 months to produce a paper. And now, I am out of ideas for new papers.

What should I do? How do I even continue? This is sooo difficult..

I want to make an alt to post on my expertise, so I want a nice instance to create the new acnt in. Which do you guys recommend? I heard good words about piefed, but not sure I would make the jump, and dont know what the consequences would be.

Just finished watching Severance 2, the Apple TV series about severance protocols. Although I liked the ending being left vague, the other parts felt rather lacking.

I can't give a specific examples, but it was like they were overly complicating the dialogue, which was presumably to appear meaningful and in depth. This also falls flat because it is so hard to follow, and whenever you follow, you realize it is shallower than expected. I could not find true deep meanings other than ice cold corporates stuff. Also, parts like switching to sudden outdoor scenes was so sudden and it seemed to rather harm the narrative.

Did I miss important details and symbolism to understand the show?

In the GrapheneOS forum, I encountered a claim that F-droid is insecure (and not good at privacy as well). These links (and more) were given as an evidence:

• https://privsec.dev/posts/android/f-droid-security-issues/
• https://xcancel.com/GrapheneOS/status/1883895255142932816#m
• https://github.com/obfusk/fdroid-fakesigner-poc

While there are some attitude against FOSS app, I think the arguments are generally sound and in good-faith. Which makes me confused, as I've been hearing good words about F-droid in lemmyverse.

I am not good at assessing arguments, so I want to ask you guys for more aspects and information.

Also, if not F-droid, what should I use? Is Aurora store, a frontend of play store, not fine to use as well?

My current phone is 7 years old, does not support recent android versions, and battery life is becoming atrocious. This feels like right time to change my phone.

Currently, I know of & am considering 3 options:

• Google Pixel
• iPhone
• Samsung Galaxy

I heard that Pixel is the best choice for privacy, despite it being Google^TM. Should I go with it, and install Graphene OS or similar options? The very fact that the name "Google" is attached makes me nervous. Also, I don't think I can trust android, so I would have to install Graphene OS or the like. In the case, app support would be lacking, though.

I am considering iPhone as well, since it has "reputation" of being secure. Of course, Apple can access my data, but that might be a good enough compromise? Honestly, I don't know. It's the best supported option as well - lots of apps support iPhone.

Galaxy is just the one that I am the most familiar with (my current one is Galaxy S8). I don't trust it, though. Do they even make good hardware nowadays?

EDIT: Turns out, Pixel phones are poorly supported by local telecomm companies. It is relatively cheap though. Still worth it?

EDIT2: I heard that data & message is fine, but the call quality is impacted by lack of VoLTE compatibility.

I am looking into password managers, as number of my accounts are increasing. Currently I am weighing two options:

• Host Vaultwarden on a VPS, or
• Use the free bitwarden service.

I want to know how they are in practical aspects.

While I am fine self-hosting many services, password managers seem to be one of the most critical services that should not admit downtime. I surely cannot keep it up, as I need to update it time to time.

On the other hand, using bitwarden might require some level of trust. How much should I trust the company to use the free service? How do I know if my passwords would be safe, not being exposed to the wide net?

I want to gauge pros and cons, are there aspects I missed? How are your opinions on this? If you are self-hosting vaultwarden, how do you manage the downtime? Thanks in advance!

I have bunch of textbooks, and a lot of lecture notes and notes from colleagues, all in PDF format. What is a good way to classify, manage, store, and read these PDF files? I am trying calibre-web, but it seems difficult to find applications to connect to it.

I am currently looking into ansibles to store my configurations and deploy services more easily.

I have couple of iptable rules in /etc/iptables/rules.v4, which I can easily restore. Meanwhile, ansible has iptable role for configurations - hence, I am confused on what approach to take.

How do I persist this rules, especially across reboots? Should I rerun ansible every time on each reboot? I am at loss on how to best manage iptables, as other services can interact with it. How do you folks handle this? Thanks in advance!

Sorry for adding to the massive pile of backup-related question, but I could not figure out how to manage backups from existing answers..

I want to backup my VPS setup (think container-defining files, its volumes, and etc configs), but am unsure where to put it. Does keeping these in the VPS itself make sense? If so, how do I create and manage the backup?

Also, I would need a remote copy - what is the good location for this? I wish I could copy to my laptop, but obviously I cannot do that automatically. Should I pay money for a backup? I want to avoid paying lots of money just for backups. Thanks in advance!

Recently, I discovered that SSH of my VPS server is constantly battered as follows.

As you can see, it is happening quite frequently, and I am worried one might break in at some point. Since SSH access guards users with root-access, it can be quite serious once penetrated. How do I harden against these kind of attacks? Because this is VPS, disabling SSH is a no-go (SSH is my only entry of access). Are there ways to stop some of these attackers?

As always, thanks in advance!
