What hardware do android phones not have making them vulnerable to cellbrite?

CalyxOS has this too. Choose between 1 and 72 hours.

In terms of industrial applications, the abstract states

We have realized all-optical wavelength conversion for a more than 200-nm-wide wavelength span at 100 Gbit s−1 without amplifying the signal and idler waves. As the 32-GBd 16-QAM is the dominant modulation format of current optical-fibre communication systems connecting the continents on Earth, the Si3N4-chip high-efficiency wavelength conversion demonstrated has a bright future in the all-optical reconfiguration of global WDM optical networks by unlocking transmission beyond the C and L bands of optical fibres and increasing the capacity of optical neuromorphic computing for artificial intelligence.

From the abstract: "we obtained a continuous-wave gain bandwidth of 330 nm in the near-infrared regime. [...] Furthermore, we realized wide all-optical wavelength conversion of single-wavelength signals beyond 100 Gbit s−1 without amplifying the signal and idler wave."

Here is the paper: https://www.nature.com/articles/s41586-025-08824-3

I think figure 4 from the PDF shows it the best. Their amplifier covers 1400 nm to 1700 nm infrared lasers.

Yes, but natural gas is a more potent greenhouse gas than co2 and there are continuous natural gas leaks. All the CO2 savings (vs coal) from each KwH of burned natural gas is completely negated by all the leaks on the way to the consumer. Note that most oil companies are very bad at reporting leaks, we basically have to measure them manually from satellites to know about them.

Never said electrification was a bad thing, just natural gas. Instead of building new natural gas plants and patting ourselves on the back for it not being coal, we should just build more renewables.

Natural gas electricity contributes more greenhouse gasses per kwh than coal though. The PRC also has lower co2 emissions per capita.

PHP does actually scale better than something like Lemmy which is written in rust

But sure, you can act like you know more than the Nextcloud devs

Isn't Opencloud just extended Nextcloud? (Still PHP)

Also, nextcloud core components are written in Rust, the PHP just handles incoming requests.

I mean that the EU wants 0 for 0.

The EU averages 2% tariffs and Trump just imposed 10-35% tariffs on the entire EU, and the European Commission just cancelled the one tariff package it managed to pass in the European Council, the one that was directly in response to the US's25% tariff that is currently in force. Trump did not cancel this tariff, but we canceled the counter-tariff to it. It's one thing to be open for negotiations, but we're turning the other cheek here.

Trump didn't pause the tariffs, he just decided to do 10% instead of 20%. (actually 35% on steel and cars now)

No backing down until we get 0 for 0.

Does antimatter have mass?

The ideological brain

In political science, a political ideology is a certain ethical set of ideals, principles, doctrines, myths, or symbols of a social movement, institution, class, or large group that explains how society should work, offering some political and cultural blueprint for a certain social order.

Saying political science and sociology aren't real science is silly.

Pretty sure the field of political science is not moral relativism

Thinking patterns are reinforced physically, makes sense.

Outside of topical debates, the key difference between conservatism and progressivism is risk taking vs risk avoidance.

No replacement mines will be running before at least 2026

35% Tarriffs on eu/Asia and 104% Tarriffs on China is still a recession. Other countries arent removing their Tarriffs

The only positive thing this did was show that Trump is weak, so hopefully he'll stay at these rates and maybe he'll be out by the end of the year

Remind me how Colorado is a border state again? Airports don't count.

Arresting people for criticizing authority is horrible, but the Trump administration doesn't really have the moral high ground here considering how they have been disappearing people for their free speech recently.

"We continue to urge Trumpist authorities to respect freedom of expression and to ensure that laws are not used to stifle permitted expression. As a treaty ally of USA, we will closely monitor this issue and advocate for the fair treatment of Fabian Schmidt," - Europe probably

SFP is the modern standard for pluggable laser modules. RJ45 sfp modules exist, but only for 1G and 10G. There's also DAC cables for sfp, but those are limited to 2-3m, and the point was to focus on the benefits of fiber. Maybe the economies of scale necessitate some modern silicon photonics like a fiber on package option, but then you have repairability issues.

The minimum bend radius is mostly because of complete internal reflection, fiber is very flexible, and it's not really possible to break an armored fiber cable by hand. You do have to worry about dust on the ends, though.

Toslink is cool, but it's a very low bandwidth standard, less than 1gbit. You need proper glass fiber and lasers for high bandwidth.
