Calling all Linux enthusiasts! Help us create a comprehensive guide to Linux firewalls and security!
i just want to also toss opnsense into that list, a long time ago it forked off pfsense and these days it offers (in my opinion) a significantly easier and better UI as well as more up to date kernel and better tools for dealing with things like buffer bloat

Yeah I don't even understand the point. The vast majority of people don't even need a client side firewall. The only time you need to worry about a client side of firewall is if you're on a laptop that you actually take out of your house ever or on a university or otherwise shared network. At home it's completely meaningless and a waste of CPU Cycles.
There are significantly better ways to address security, like how to enable a sandbox like firejail or bubblewrap or enable things like apparmor, firewall is probably one of the most inconsequential parts of security these days because it's all handled by the local router
You should switch to Firefox instantly then, because the amount of add-ons capable of doing that for you are endless.
The problem is that many people can afford it, but the apartments want them to have absolutely asinine levels of income. Many apartments are starting to ask for anywhere from 3 to 4 times the rent in monthly income. And considering that even a one bedroom apartment in many cities is starting to cost upwards of over $2,000 they want you to make $6,000 to $8,000 in monthly income at which point why the actual fuck would I be looking for a shitty one bedroom apartment. They already asked for first month rent last month rent and a deposit that should be enough to prove that I'm capable of managing my money
Actually it's pretty easy. While not necessarily universally true, 98% of the time if there is a question mark everything after it is completely useless and can be removed.
for example of youtube, if you just use the share link from mobile you will get something like this

However the only thing needed is
discord is similar, share a picture and you get shit like
but all that's needed is

the ? is almost always used as an escape from the actual url. So if you see a question mark, Just remove everything after it and things will most likely still work.
I'd say and cars just think about how many bug splatters you see on an average decent trip on the highway now multiply that by the millions of cars on the road daily. It's not the root cause but it certainly didn't help
Honestly the only time I've really had that issue is if I'm trying to use an Excel or Word document with a lot of macros. For basic text which is what 99% of people need I've never had any issues opening or saving a word document with LibreOffice, and I regularly submit documents to government offices because I work for a county department in my area.
I'm mostly only replying to one part of your message, the reason everyone uses it is not that it's more simple. For 99% of people the only thing they need is the web browser and maybe possibly office depending on what they do for work. At which point the experience between Windows and Linux is like 99% the same
Windows also constantly has issues and headaches as you alluded to with your error codes. People are just used to how to Google and try and sit there and deal with it for a couple hours.
Windows is the default, because it's the default. Because it's what your computer comes with, because it's what everyone grew up using. It's just tyranny of the default and nothing more. I got tired of dealing with Windows issues for my family as the resident Tech person so I gave them an ultimatum they can either let me give them Linux or they can find someone else to call when something goes wrong. Some of them took me up on my Linux offer, and I have happily not had to touch their computers in I think about 6 years now. They quietly do updates on their own on a schedule send me a push notification if it fails for some reason which so far none of them have and those people only ever used to the web browser and office anyway and for their needs LibreOffice was perfectly functional they don't do anything fancy they don't do a ton of macros they just type basic text with maybe some bullet point formatting

This is a nice little experiment to show you what happens when you try to parallel two inverters that are not synchronized. Just because the voltage matches does not mean they are in the same phase or synced up with their sine waves. You can also just look at the manual for any dedicated off-grid only solar inverter and they will make it very clear that you are not supposed to hook the output up to the mains panel and doing so will void your warranty and damage the unit. But I'm sure that those inverter manufacturers have no idea what they're talking about /s
I'm not really sure what you are talking about, you need to synchronize both the phase of the power and the frequency. If they differ even slightly you damage your equipment. This is why when running multiple inverters in parallel they require both a Communication cable and a power sharing Cable in order to ensure that they stay perfectly synchronized. Inverters capable of doing grid tie have equipment in them to monitor the mains power and make sure that they stay synchronized with it. Whereas an off-grid inverter does not contain that equipment which is why they are generally cheaper
There are several different possible phases for 120 volt they are not all the same. And while hooking to the mains may be standard practice for something that can grid tie it is not standard practice for an off-grid inverter. You are specifically expected to have a secondary panel specifically for that inverter. The mains power will reach that secondary panel through the inverter when it's in pass through but the panel should in no way be connected to the mains directly (other than a ground bond between the secondary panel and the mains)
With that having been said, I have no doubt that solar installers have instead opted to continue to use inverters that are capable of grid tie even in a installation that will not be backfeeding. Probably just to reduce the amount of inventory required so that they can get full purchase orders. But that doesn't change the fact that a proper true off-grid inverter is not capable of tying into the mains without destroying itself
The fact that you say you were a solar installer, but you're not even aware of something as simple as phases and frequency synchronization is part of the reason I feel like solar installers are wildly overpaid. You're basically doing the bare minimum without really understanding what it is you're doing
That doesn't really make sense, since an off-grid inverter literally cannot backfeed. It's essentially just a computer UPS on steroids. It accepts the grid as an input that it can pass through but it's not possible for it to push energy back to the grid.
I mean yes if you decided to hook its output directly up to your Mains panel without separation you would be back feeding. But only for maybe a few minutes at most as you would also destroy your inverter because it has no mechanism to synchronize the output with the mains since it's not designed to backfeed
good, fuck em. Seeing houses as an equity Builder was retarded in the first place. It's literally not sustainable, if it's supposed to constantly appreciate value no matter what it means that there is an ultimate threshold where it becomes unaffordable for everyone.
A house is a place to live, not a fucking financial asset to make money with.
I can't think of any One-Stop shop for literally everything, but there is a lot of great material out there both on forums and on YouTube. If you take it one step at a time and look at each individual piece of the installation you'll be able to find fantastic instructions for all of them fairly easily.
If you are in the US I recommend purchasing from signature solar, they have a lot of great bundles that will both save you some money and get you everything you need. I'd also say they have the best battery storage options, their rack mount batteries and their new wall mount battery are both fantastic and very easy to work with. They also sell solar panels by the pallet which helps you get a nice large array at a good price.
If I had to pick the hardest part it would just be making sure you get the grounding right on the inverter, if you're not careful it's pretty easy to end up with a ground Loop which isn't particularly dangerous but it will cause lots of weird little issues like flickering lights and other annoyances. But it's fairly easy to correct it it's usually just a result of people connecting both the input and the output on the inverter as well as bonding the secondary panel to the primary panel which creates a ground loop. The solution is as simple as just don't connect to the input power ground to the inverter only connect to the output ground so that it has to go through the ground Bond on the panels
It will definitely sound like a lot, but again if you just take each individual piece by itself it's very straightforward very simple and you'll be able to get it done while saving an absolute asinine amount of money compared to an installer.
I will warn you that if you try to do gridtie, which is where you're able to send excess electricity back into the grid. That comes with a lot more red tape and can get a lot more complicated. I personally did an off-grid setup, which still uses the grid as a possible input so if my batteries are dead and there's no sun out I can still use the power like normal it's just not capable of sending Excess power back out into the grid so there's a whole bunch of red tape that I don't have to worry about.
If you are willing to DIY you can cut that number dramatically. Out of curiosity what was the size of the array in that quote and did it include battery storage if so how much chances are that you can cut it by anywhere from 50% to 75% if you're willing to Simply purchase directly and install yourself. The amount that installers charge is absolutely asinine usually 50% or more of that quote is just the installation which is in the same because it's not difficult at all. People like to act scared like oh that'll be difficult or hard or dangerous, it's extremely simple you're dealing with DC which is very straightforward everything is very clearly labeled on that equipment and it's quite simple to do yourself
I would like to recommend Seafile if immich doesn't work out. I've used it for a long time and it's always been the best self hosted cloud imo. it's not as shiny or pretty looking as some but it's been reliable
thank you, I can't believe I missed that I guess I just kept glancing over it assuming it was a header without reading it. I could delete my post but I will simply accept my shame
i just want to also toss opnsense into that list, a long time ago it forked off pfsense and these days it offers (in my opinion) a significantly easier and better UI as well as more up to date kernel and better tools for dealing with things like buffer bloat
