Ich war gestern bei den Waldschweinen. Da hat ein Schwein rund 1.000m² Platz. Wenn man das gesehen hat, wie geil die das finden muss man sich an den Kopf fassen, dass ein anderes Schwein nur 0,75m² hat. Das ist schon pervers.
Ich befürchte ich kann nicht 100% auf Fleisch verzichten, fällt mir echt schwer. Aber dann lieber 1-2x in der Woche das teure Fleisch der Waldschweine als jeden Tag Fleisch zu Mittag.

Here's a crazy idea. What if down voting a comment/post resulted in a weighted random float between 0-1 while upvoting resulted in a weighted random float between 1-2? If you virulently hate a comment or post, ignoring it is the surest way to bury in completely. Posts and comments that Garner attention become the most visible, but gaming the system for visibility could become difficult if the weighting algorithm was tuned appropriately.
Kam ja gestern ziemlich plötzlich, war auch zeitweise recht spannend, aber das Ende war in meinen Augen nicht gelungen. Aktuell sieht es so aus, wie wenn der Protagonist eine weitere Staffel bleibt trotz nicht besonders gutem Auftritt (nur 3,24 von 10 Punkten im Demokratieindex).....
Also wenn das ein Cliffhanger gewesen sein soll, dann war der echt schlecht ausgeführt. So richtig abrupt von 100 auf 0. Als wäre die Episode von Dumb & Dumber (die Typen von Game of Thrones) geschrieben worden.
Any guides on how to host at home? I'm always afraid that opening ports in my home router means taking the heavy risk of being hacked. Does using something like CloudFlare help? I am a complete beginner....
I do as well on a non-standard port, although that doesn't really provide any extra security. I found ssh only login acceptably secure personally, but it's definitely less secure than tailscale which can operate with 0 open ports. The risk would be from os/sshd vulnerabilities that can be exploited. As long as you keep the router up to date it should be safe enough.
But is it still when many have 0 kids or only two between 30 and 45. Now we regularly live to 80 is one partner in our 20s then our middle age then into old age still valid.
You’re correct, but the two groups that are anti nuclear are Boomers and The Greens parties.
Boomers are easy, they grew up with a few nuclear incidents, including reactor issues as well as the USSR stuff.
The Greens is paradoxal, youd think they were pronuclear, at least in the interrum. But they are anti nuclear because of a variety of reasons. So you see situations like in Germany recently where the Greens forced the government to get rid of nuclear reactors, and in their place, comes more Gas reactors… Greens want 100% renewable, but don’t seem to understand that they should be fighting for 0% fossil first … then when that’s obtained go for 100% renewables.
Because every time you remove a nuclear reactor, the only firm power replacement is a fossil fuel reactor.
I say this as a lifelong Greens voter, my political party have a small, and vocal group of idiots.
(In case you’re wondering, yes the anti nuclear Greens are usually boomers)
Hi! I'm a nuclear engineer. I just wanted to do a small drive-by clarification/lecture.
There are a lot of feedbacks that are considered when designing a nuclear reactor, it's not just a single void coefficient. There are thermal feedbacks, feedbacks related to the decay of fission products, feedbacks related to the burnup of fuel, the burnup of the neutron poisons, the activation of the water in the primary loop, etc etc. When designing a nuclear reactor, all of these effects must be examined. Generally, this involves finding the transfer function and confirming that all the poles of the transfer function have real part less than 0. (This is where the "negative" part comes in, they're complex numbers in general, but as long as the real part is less than zero this corresponds to a decaying exponential.)
An aside on criticality. We are quite fortunate in that due to a quirk of nuclear physics, fission reactors are possible. We call the time difference between one fission and the next from the neutrons produced a "generation." If we had to react on the timescales of a "generation" based on the simple model where one fission leads directly to another, then we'd have to react in milliseconds, and this just wouldn't be possible to make a reactor safe, even with an extremely well designed system of feedbacks. However, some fission products will decay and release a neutron, these so-called delayed neutrons make controlling a nuclear reactor on human time scales possible (minutes and hours instead of milliseconds), and it makes these feedback loops far more stable. So we aim to keep the criticality below 1 for "prompt" neutrons, and slightly above 1 for delayed neutrons, then we rely on the feedback systems (primarily thermal and fission products) to keep the criticality oscillating very slowly around 1.
For specifically Chernobyl, there is a more broad idea that we concentrate on in reactor design, that of overmoderation vs undermoderation. Reactivity has a relative peak at a particular amount of moderation, and we want to design the reactor in such a way that it can never get more moderated than that peak, because that would give a positive feedback loop if increasing the power led to a concomitant decrease in moderation (which is normal, the density of liquid water decreases with increasing temperature). Because Chernobyl was graphite moderated and steam cooled, we had an especially bad case of this where the core flooded and was massively overmoderated, and in order to get the water out of the core they attempted to turn the reactor all of the way up and boil it out, but in doing so this caused the reactivity to go massively supercritical as the moderation was reduced from absolutely smothering the reaction to just right. It was so supercritical that it was supercritical only with the prompt neutrons, so-called prompt supercriticality, which is why you read things like the power went up 1000x in a second.
The United States does not, and did not even at the time, allow certification of designs where it is possible for this to occur. All reactors must have negative reaction coefficients for all major feedbacks in all operating scenarios, and, in fact, due to this stringent process there are only 4 reactor types that the NRC has currently certified for new nuclear reactors (with 3 more currently under review), (and each design has to be certified jointly with the location where it will be built, so something like Fukushima, where the backup generators are in the basement in a flood zone, would not pass certification review in the US.)
Anyway, I hope this was interesting and educational.
I'm one of those guys. I voted to ban nuclear here in 2017.
I absolutely would love to put 0% fossil before 100% renewable. But as long as nuclear was a choice little more than token efforts were made to expand renewable capacity. Then we banned it and suddenly solar installations are sprouting like mushrooms. Before the ban we put in 330MW per year. The increase in the increase in solar was this much last year (670->1000MW)!
This month we had another vote in a climate bill and as soon as that was accepted the regressives came out and called for more nuclear and complained how all that solar and wind is going to ruin christmas the landscape. I'd love to have renewables AND nuclear but somehow it always ends up being an OR...
Just to be clear: This isn't an attack on pro-nuclear folks. I get your point and in theory you're right. I just never seen it put into practice...
In Deutschland wird durch unsere Noten gemessen, wie viel wir gelernt haben. Unsere Noten entscheiden dabei über unsere Zukunft: werden wir in die nächste Stufe versetzt? Welche Ausbildungen dürfen wir antreten? Kommen wir das Studium anfangen, welches wir uns wünschen? Welche Jobs bekommen wir?...
Teilweise sind Noten auch extrem von irgendwelchen Schulsystem-Reformen abhängig. Ich hab in Sachsen Abitur gemacht, als sie für zwei oder drei Jahre eingeführt hatten, dass alle Noten in allen Fächern in die Abiturnote einfließen und man nur sehr begrenzt Fächer abwählen durfte. Vorher und nachher konnte man schlechte Semester einfach rauswerfen. Hat dann dazu geführt, dass in diesen drei Jahrgängen niemand eine 1,0 geschafft hat, davor und danach aber immer mehrere Personen.
Die volkswirtschaftlichen Kosten des Niedrigwassers sind erstaunlich hoch: „Auf Jahressicht dürfte das Niedrigwasser etwa 0,4 Prozent an Wirtschaftsleistung gekostet haben“, rechnete das Kiel Institut für Weltwirtschaft 2022 vor.
Das finde ich beeindruckend. Landwirtschaft macht doch nicht soo viel unserer Volkswirtschaft aus, oder?

There’s no battle pass, no cosmetic store (though there is a $20 “Supporter Pack” that comes with gun skins)
The fact that they already have “a” microtransaction available means they invested a significant amount of time building out the infrastructure required to support them, there is a 0% chance they aren’t planning on putting in more once the game gets big
Prigozhin decides "if I'm dead anyway, I'm taking Putin with me"
Lukashenko somehow convinces Prigozhin that "it's ok, Putin changed his mind and won't kill you anymore" - so Prigozhin no longer feels the need to go for a suicide mission (although how Lukashenko convinced Prigozhin of this, I have no idea)
If this had really been about Shoigu or a coup or anything other than just a suicide mission, then the current result makes 0 sense. (But in that case, maybe the situation isn't really over at all)
