First he came for the Gulf of Mexico, and I did not cry out, because I was not Mexico. Then he came for the Department of Defense, and I did not cry out, because I did not need defense. Then he came for the football, and … HOLY SHIT that’s a lot of angry football fans!

Most of the countries in the western world have spent so long not really being at risk of being at war that we really have no idea how to react to potentially actually being at war. We are so incredibly unprepared in such incredibly profound ways. Imagine being in a war and not having anti-air defenses around your most important strategic nuclear sites and having to rely on troops shooting at incoming aircraft with what I suspect were simply their service weapons, and almost certainly not even dedicated anti-drone weapons. Yes, drones are sort of new, that’s not really an excuse. New things will happen during a war. You have to be able to react quickly to defend your critical assets at a moment’s notice. The fact that we’re still not doing that properly is a perfect demonstration of how far behind the curve we really are.

I hope this changes soon with the sprawling investments being directed towards defense budgets, but I remain unconvinced, will it just result in more hyper-capable, hyper-expensive techno-wonderweapons? It’s the cheap, good-enough, high-supply things that are currently threatening us, and both history and the present seem to tell us it’s usually the cheap, good enough, high-supply things that both win wars and enable effective defense. Spending money seems like it would imply seriousness, but I don’t think we’re actually taking this seriously enough, yet. When you really get serious about war and defense you need to be asking the real questions about what it’s going to take to win, not just throwing money at the problem.

Maybe I’m wrong, maybe they’re just sandbagging and waiting for the right moment to reveal our true defensive preparations, but I know a lot of people in various western militaries, and I honestly don’t think so at all, and neither do they. If we are more prepared than we look, it’s a pretty goddamn well-kept secret.

The first problem would be the height of the intervening terrain and even if you could overcome that, you still have to contend with friction inside the pipe which is a factor most people don’t think about for short distances but when you start trying to carry water long distances through a pipe, friction becomes massive. An ideal siphon inside an ideal pipe is simply a question of height between source and destination. However in the real world, a siphon isn’t unlimited or ideal. There is a height it can’t overcome and it’s actually not very high at all, geographically speaking. The maximum height of a siphon is only around 10 meters. The terrain between the Red Sea and the Dead Sea is pretty flat, but it’s probably not that flat. I’m not going to pretend I’ve done a precise survey of potential routes, but I’d expect there’s probably some bumps in elevation along the way that’s realistically going to need say, 100 meters of lift to overcome. But even 11 meters would simply end the conversation. There’s simply no way around that for a siphon.

The reason for this height limitation has to do with the atmospheric pressure required to keep the water liquid, because once it no longer has enough pressure on it to keep it liquid, it simply vaporizes before it reaches the height it needs to and the siphon is broken before it even starts. In a vacuum, at standard temperature, water instantly vaporizes. The external atmospheric pressure (which is acting on the entire water column up to its highest point, to get it over the hill) is all that is keeping the water in its liquid form inside the siphon. The higher you go, the more work that external pressure is doing, and eventually the weight of the water column exceeds the pressure at the bottom of the water column and again, the siphon breaks.

The friction is the other problem. Even if you could limit your route to no more than 10 meters above the Red Sea, you’re also asking the siphon to not only lift it to that height, but also carry that water through 200 kilometers of pipe or more. We don’t think of pipes as having friction, but they do, and it’s very significant at those distances, especially when your power source (gravity, in this case) is already operating near its absolute limits due to the height problem we already discussed. What you hoped would be a gusher of a siphon will end up being a trickle, if anything at all, with most of the water just sitting idle in the pipe to maintain the siphon while a little dribbles its way slowly through to the destination.

Finally you’ve got all kinds of other more obscure effects at play at those scales, like water’s surface tension, variability of flow rates, possible pinhole leaks in the pipe that will introduce air, offgassing of dissolved gases in the water or even from the pipe itself, and temperature gradients inside the pipe. All of these are going to play havoc with the ability to form and sustain a reliable siphon.

In short, siphons are actually pretty limited, we don’t see much of those limitations on the small scale, but on the larger scale of this project those limitations become very serious, very quickly and basically remove the possibility of using a siphon for any realistic practical water relocation project. Almost all of those go away very quickly when you pressurize the system with a pump instead of relying on atmospheric pressure alone. It’s a fun thought experiment, but in practice a simple electric pump turns out to be a pretty cheap way to solve a lot of otherwise really complex hydrodynamic problems, and when that’s the case, it’s not really worth teasing out a solution to those problems with all kinds of complicated engineering. Just throw a pump at the problem and call it a day, job done.

I thought it was supposed to be closed at one point, it wouldn’t surprise me to learn that never happened but I’m still not fully clear on its status. The article talks about it in present tense, but even the comments here are talking about it in past tense? Are other people also thinking it’s closed? Is it actually still open? What’s the deal?

Ah yes, the famously reliable, safe, and effective Russian submarines, workhorse of the Russian navy. What should they buy next? Some guided missile cruisers? How about an aircraft carrier?

You may not agree with what the military does, but you have to respect them for that reason alone, above all else.

This premise must be rejected. You do NOT have to respect them for that reason alone, and certainly not above all else.

Did Nazi soldiers deserve respect, because they were just following orders and they followed those orders and what options did they really have? Were they not also facing the potential of harsh punishment if they did not?

Not having good alternative options is not an excuse for following orders you know are wrong. Respect is earned when your morality supersedes your orders, despite the potential (and sometimes very real and significant) punishments. Your intentions only get you so far, eventually you need to act or else any remaining respect for you will be gone.

This looks less intimidating than Authentik. Any guides on getting it set up with any common self-hosted stuff?

The US is not “discovering” the corruption, the US is creating the corruption.

Ukraine meanwhile is caught between two (self-styled and failing) superpowers through little to no fault of their own, and that is obviously not a great place to be.

Sounds great, I’ll plan on waiting a year or so until I’m convinced they’ve got the bugs worked out, and then buy it just before they announce a new and upgraded version, as is tradition.

Looks really nice and seems like it should be a great foundation for future development. Personally I can’t lose Nextcloud until there are sufficiently featureful and reliable clients for Linux, Windows, Android that synchronize a local copy and help manage the inevitable file deconfliction (Nextcloud Desktop only barely qualifies at this, but it does technically qualify and that represents the minimum viable product for me). I’m not sure a WebDav client alone is enough to satisfy this criteria, but I am not going to pretend I am actually familiar with any WebDav clients so maybe they already exist.

You’re on the right track. Like everything else in self-hosting you will learn and develop new strategies and scale things up to an appropriate level as you go and as your homelab grows. I think the key is to start with something immediately achievable, and iterate fast, aiming for continuous improvement.

My first idea was much like yours, very traditional documentation, with words, in a document. I quickly found the same thing you did, it’s half-baked and insufficient. There’s simply no way to make make it match the actual state of the system perfectly and it is simply inadequate to use English alone to explain what I did because that ends up being too vague to be useful in a technical sense.

My next realization was that in most cases what I really wanted was to be able to know every single command I had ever run, basically without exception. So I started documenting that instead of focusing on the wording and the explanations. Then I started to feel like I wasn’t capturing every command reliably because I would get distracted trying to figure out a problem and forget to, and it was duplication of effort to copy and paste commands from the console to the document or vice versa. That turned into the idea of collecting bunches of commands together into a script, that I could potentially just run, which would at least reduce the risk of gaps and missing steps. Then I could put the commands I wanted to run right into the script, run the script, and then save it for posterity, knowing I’d accurately captured both the commands I ran and the changes I made to get it working by keeping it in version control.

But upon attempting to do so, I found that just a bunch of long lists of commands on their own isn’t terribly useful so I started to group all the lists up, attempting to find commonalities by things like server or service, and then starting organize them better into scripts for different roles and intents that I could apply to any server or service, and over time this started to develop into quite a library of scripts. As I was doing this organizing I realized that as long as I made sure the script was functionally idempotent (doesn’t change behaviors or duplicate work when run repeatedly, it’s an important concept) I can guarantee that all my commands are properly documented and also that they have all been run – and if they haven’t, or I’m not sure, I can just run the script again as it’s supposed to always be safe to re-run no matter what state the system is in. So I started moving more and more to this strategy, until I realized that if I just organized this well enough, and made the scripts run automatically when they are changed or updated, I could not only improve my guarantees of having all these commands reliably run, but also quickly run them on many different servers and services all at once without even having to think about it.

There are some downsides of course, this leaves the potential of bugs in the scripts that make it not idempotent or not safe to re-run, and the only thing I can do is try to make sure they don’t happen, and if they do, identify and fix these bugs when they happen. The next step is probably to have some kind of testing process and environment (preferably automated) but now I’m really getting into the weeds. But at least I don’t really have any concerns that my system is undocumented anymore. I can quickly reference almost anything it’s doing or how it’s set up. That said, one other risk is that the system of scripts and automation becomes so complex that they start being too complex to quickly untangle, and at that point I’ll need better documentation for them. And ultimately you get into a circle of how do you validate the things your scripts are doing are actually working and doing what you expect them to do and that nothing is being missed, and usually you run back into the same ideas that doomed your documentation from the start, consistency and accuracy.

It also opens an attack vector, where somebody gaining access to these scripts not only gains all the most detailed knowledge of how your system is configured but also the potential to inject commands into those scripts and run them anywhere, so you have to make sure to treat these scripts and systems like the crown jewels they are. If they are compromised, you are in serious trouble.

By now I have of course realized (and you all probably have too) that I have independently re-invented infrastructure-as-code. There are tools and systems (ansible and terraform come to mind) to help you do this, and at some point I may decide to take advantage of them but personally I’m not there yet. Maybe soon. If you want to skip the intermediate steps I did, you might even be able to skip directly to that approach. But personally I think there is value in the process, it helps defining your needs and building your understanding that there really isn’t anything magical going on behind the scenes and that may help prevent these tools from turning into a black box which isn’t actually going to help you understand your system.

Do I have a perfect system? Of course not. In a lot of ways it’s probably horrific and I’m sure there are more experienced professionals out there cringing or perhaps already furiously warming up their keyboards. But I learned a lot, understand a lot more than I did when I started, and you can too. Maybe you’ll follow the same path I did, maybe you won’t. But you’ll get there.

Xi understands that Trump is a stupid man and they think they can manipulate him into doing something stupid to advance their interests, which, honestly, they probably can, unless he just does something so stupid that it backfires. Everything’s a gamble with Trump.

Nextcloud is just really slow. It is what it is, I don’t use it for any things that are huge, numerous, or need speed. For that I use SyncThing or something even more specialized depending on what exactly I’m trying to do.

Nextcloud is just my easy and convenient little dropbox, and I treat it like it’s an oldschool free dropbox with limited space that’s going to nag me to upgrade if I put too much stuff in it. It won’t nag me to upgrade, but it will get slow. So I just don’t stress it out. So I only use it to store little convenience things that I want easy access to on all my machines without any fuss. For documents and “home directory” and syncing my calendars and stuff like that it’s great and serves the purpose.

I haven’t used Seafile. Features sound good, minus the AI buzzword soup, but it looks a little too corporate-enterprisey for me, with minimal commitment to open source and no actual link to anything open source on their website, I don’t doubt that it exists, somewhere, but that raises red flags for potential future (if not in-progress) enshittification to me. After eventually finding their github repo (with no help from them) I finally found a link to build instructions and… it’s a broken link. They don’t seem to actually be looking for contributions or they’re just going through the motions. Open source “community” is clearly not the target audience for their “community edition”, not really.

I’ll stick to SyncThing.

Hey don’t make fun of him too much, he might have to buy another yacht to make himself feel better.

And most importantly what happens when the competition between many extra doordashers drives down pay (the mechanism for which is already built in to the way gig work pays by the gig, fewer of which will be split between more drivers) means even the people working for doordash can no longer afford lunch?

This is not sustainable in the slightest. We are using bubbles to cushion our falls from other bubbles as they pop. It’s bubbles all the way down. We’re in a recession, maybe a depression, hard to say because there are so many bubbles we haven’t even reached the ground yet.

The problem is that society has been much too polite with these shitgoblins. I think we should end polite society entirely and start being really thoroughly impolite.

It was, and still is. It hasn’t moved to the US, it just also opened a nonprofit there, so the US donations they receive from US people are tax deductible in the US. If I remember correctly they have also opened a non-profit in Belgium which is I think where they are intending to actually move their assets and do most of their work going forward as I think they’ve had various issues with the German organization also.

We should skip the whole world war step and go straight to Nuremburg 2.0, now improved with faster sentencing and harsher sentences for fascists and collaborators.

They have declared war on humanity. They will replace us with AI and rocket fuel as soon as they are able to.

It’s definitely not burn-in, it’s likely some kind of defect in the backlighting system. For most LCDs the “backlight” is essentially a big thin white/mirrored panel reflecting or diffusing light in a very carefully consistent way from a very bright light source, typically either a fluorescent tube at the bottom or more commonly nowadays evenly spaced strips of LEDs. Some higher end models use more elaborate designs but they’re the minority. Defects in the backlight panel, the back of the LCD panel, or stuff like dust or even insects getting inside that reflective/diffuser chamber will affect the consistency of the backlight as it both blocks a bit of the light from reaching some places and reflects it to other places it shouldn’t be. That’s what it looks like is happening here. It could be some kind of delamination of some of the surfaces inside the TV, or it could be some puff of dust that somehow got inside, or even something like a spider decided that was a great place for a cobweb. Without opening the panel it’s hard to say what’s going on exactly, it might just need a very delicate cleaning or it might need replacement parts.

If you’re afraid of spiders, I’m sorry, you just have to burn the house down now, it’s the only way to be sure.
