Thank you for saying this. If you want to know the answer to what causes climate problems, you need to go back to the era of dinosaurs, where CO2 levels were multiple times higher than today. Trees could thrive because they could breathe in a lot of CO2. Dinosaurs got so big because there were plenty of food. How could dinosaurs happily live with such high CO2 levels? The key is that there were plenty of forests. Peter Wohlleben's book "The Power of Trees: How Ancient Forests Can Save Us if We Let Them" explains how forests naturally circulate water.

I am treated so unfairly, it's unbelieavable. People with insults get away without punishment, but my innocent screenshot is invisible.

I posted my screenshot yesterday but it's not visible. I don't care anymore.

Sure, it's reported by the Radeon Software, but I'll check HWiNFO64 soon and post a screenshot.

I can't confirm the 40W, my Ryzen 9 7900 (non-X) consumes 1W to 3W at idle on Windows 10.

It's the 3D cache, as I wrote in my other response. It has to be powered on at all times, so it affects even the idle power usage.

What are you talking about? AMD has been really good at the power efficiency department until the 3D CPUs that use extra power for cache memory that simply cannot be turned off. Plus, Intel started applying the 3nm fabrication process, while AMD is still at 4nm. But previously, Intel was at 10nm for a long time, see i9-13900K for example, while Ryzen went to 5nm much sooner, see Ryzen 9 7900x.

Exactly, your phone can break or get stolen any time. Plus I just don't want to limit myself to a single device.

What I missed from the article is the usual: biometric authentication is not secure.

(Yes, I'm linking YouTube because unlike popular belief, some channels are actually informative, or some make it easy for us to understand the content.)

I would never use my fingerprint for authentication, because it's a flawed concept. The problem is, that your fingerprint is not a password. It's more like a username. That's because you leave your fingerprint everywhere, it's practically public information. The same can be told about your face.

On the GrapheneOS forum you will see a lot of bad opinions about F-Droid, for example this:

> It doesn't matter that the app is trustworthy, because F-Droid are extremely incompetent with security and the apps you install from F-Droid are signed by F-Droid rather than the developer.

https://discuss.grapheneos.org/d/20212-f-droid-security-in-s... https://discuss.grapheneos.org/d/18731-f-droid-vulnerability...

They also say, if you use F-Droid, at least use F-Droid Basic:

> Dont use the main F-Droid client. Android is pretty strict about SDK versions and as F-Droid targets legacy devices, it is very outdated.

https://discuss.grapheneos.org/d/11439-f-droid-vsor-droid-if...

> If the app is only available on F-Droid / third party F-Droid repo, use F-Droid Basic and use the third party repo rather than the main repo if available. > > If the app is available on Github then install the APK first from Github then auto-update it using Obtanium. Be sure to check the hash using AppVerifier which can be installed from Accrescent (available on the GrapheneOS app store).

https://discuss.grapheneos.org/d/16589-obtainium-f-droid-bas...

By the way, while GrapheneOS recommends Accrescent, I don't use it anymore because they can't even add apps like CoMaps, while some of the apps they actually added are proprietary.

Also learn grammar, please. If you mean a canvas based on IPv6, then write "IPv6-Based Canvas". If you mean IPv6 has based the canvas, then write what you just did.

Please read the article again, he does explain the torture:

> our phones make us feel powerless; as if we must fight our devices to get anything done. There’s a constant barrage of notifications, and by the time you have dealt with them, chances are you have forgotten what you wanted to do in the first place. Then there is Gemini, Google’s artificial intelligence bot, which won’t leave you alone. Press the home (middle) button for half a second too long, and it pops up, offering to “assist” you.

The closed-source part has been explained too, as it links another article: https://www.osnews.com/story/142553/rumour-google-intends-to...

"The Android Open Source Project has been gutted over the years, with Google leaving more and more parts of it to languish, while moving a lot of code and functionality into proprietary components like Google Mobile Services and Google Play Services. Taking “Pixel Android” closed source almost feels like the natural next step in the process of gutting AOSP that’s been ongoing for well over a decade."

Cool idea, but I could just run a Commodore 64 emulator on my PC these days.

I'm disappointed. 8B is too low for GPUs with 16 GB VRAM (which is still common in affordable PCs), where most 13B to 16B models could still be easily run, depending on the quantization.

If you guess at random, that's 25% probability to get the right answers, which gets you 7/28 points in average. I got 14/28 by trying hard and I still hate the result, but it's also true that the questions were largely impractical: noone parses dates like this in a real production app. We always validate the date format first. So noone should feel bad at their results.

Thank you! Totally agreed!

Continuing my previous comment, to address that:

> There is data that reaches back to a pre-human time where the world was indeed very different, and if you go far enough into the past CO2 levels were extremely high. However, the planets environment also looked very different in that period.

Yes it is true that in the history of the Earth, CO2 levels were the highest during the first few hundred million years (5000 to 7000 ppm), see this image:

https://youtu.be/chDcDyG4uLQ?t=352

But this image also shows in large scale what really matters: dinosaurs could live when the CO2 concentration was 2500 ppm! What we are experiencing now is what happened 300 million years ago: the CO2 levels were naturally increasing even before the era of dinosaurs. We are currently in an ice age based on the graph. So why is it warming today then? We’re coming out of a mini ice age on a smaller scale, see this pic:

https://youtu.be/chDcDyG4uLQ?t=692

The Earth naturally experiences warmer and colder times. And the effects of it are what you just described. Like it or not, the causes are natural and we can’t do much about it. Except one thing: restoring more forests, to retain water, and absorb more sunlight. But you can’t prevent the arctic ice from melting. You can just get used to it:

https://youtu.be/chDcDyG4uLQ?t=3693

The politicians are trying to defend against 1 or 2 Celsius degrees of change, when Central Europe is heading towards a mediterranean climate just because of Earth’s ever-changing tilt and orbit. Eventually we might see +50 degrees just because of that. So rather, the goal should be adaptation.

It's still what I consider true, and I stated my sources, then you flagged it. The Earth is coming out of an ice age. This time, I properly stated my sources from the start, and you still attack me with your sense of truth. Which may not be the truth.

So you call me a comedian after pointing to the comment where I state my facts, and you don't downvote or even flag yourself? This is double standards on Hacker News.
