I find this misleading. Today, most fonts in practical use are open source fonts. When someone chooses a font for a web project, they typically pick something from Google fonts, which are all open source licensed. Android, the most common O

I haven't said you can't discuss them, I was pushing back against the idea that this is easy.

Not my experience, and I do this regularly. Scientists are often happy when people are interested in their research.

> Hydrogen is a better solution for [...] industrial processes that need very high heat. Why would that be, except maybe in rare cornercases? You can electrify almost anything, and it'll be more efficient and less polluting.

You're confusing primary energy with useful energy. What people need to realize is that if we go to renewable, electric energy, in most cases this will also involve efficiency improvements. Many fossil fuel based processes are horribly

Eventually you run into issues with your stack being incompatible with the rest of the world. Your 20 year old debian won't be able to provide a TLS stack that is compatible with any modern browsers. And you could argue that this is st

Yeah, that's the perfect symbol of what's wrong... "Our river is so dirty, it's too dangerous to swim in there. Let's build a swimming pool into the river!"

Well, Berlin has the same issue. Unlike Paris, it has no plan of cleaning up the Spree any time soon. It has been discussed every now and then, but it's always too complicated, or the solutions available aren't liked by the people

Generally asan+msan detect more errors, and some quite significant ones. For design reasons, valgrind cannot detect most stack oob bugs. The only issue with msan is that it's a bit trickier to use, particularly if you have lots of depe

Yes. I mean, that's happening. Some of the CO2 automatically ends up in the ocean, which reduces the burden for the atmosphere. But what you probably meant is if we can artificially increase the CO2 dissolved in sea water. The answer i

It's nonsense like this that makes a more rational debate around carbon capture difficult. Yes, CCS will likely have to play some role in a future decarbonized society, e.g. for cement production. But it's not a plausible lifeline

That is... interesting that they do not even use HTTPS or any type of signature for that info. So a man in the middle could prevent updates from happening, and freshclam wouldn't even throw a warning?

None. We're in the stage of early research, still trying to figure out how practical it is to build useful QCs at all. Anyone claiming otherwise is trying to fool people. Maybe QCs will have useful applications in the future. Maybe not

The thing is: Most of that infrastructure is obsolete in any case. These synthetic chemicals will play a role in industry and shipping, probably also in long-duration storage. But they won't be in widespread use like fossil gas today.
257.
by hannob 3y ago
None of these chemicals will be used in people's homes in any meaningful quantity. That's just not going to happen due to the conersion inefficiencies.

> Methanol production requires methane as a synthesis gas so it just adds another step. That's not true. Methanol can be made directly from CO2 and H2. This has been tried more than a decade ago: https://www.carbonrecycli

When considering synthetic chemicals made from solar energy, methane is probably one of the last you should consider. Making any type of chemical energy carrier comes with substantial losses, so whenever you can, using electricity directly

The problem is really that if you want to be free and open source software then you can't have an anti AWS or anti big cloud clause. And that's what the issue with SSPL and others was. If they had said "open source didn'

For a library like libjpeg-turbo, it's probably best that it stays in maintenance mode. I mean... it's JPG. It's the traditional lossy image format that everyone's been using since forever, and that hasn't received

That's not all that clear. The problems QCs could solve regarding crypto are from number theory. That's basically a branch of math that doesn't really describe any real-world stuff. Cryptography is as far as I know the only p

This is probably a good example why naive market economics thinking is problematic. Any "ideal market" assumes some kind of demand elasticity, i.e. people will buy more when it's cheap and less when it's expensive. But f

That makes no sense. Methane has a global warming potential of around 28 over 100 years, meaning it causes 28x as much warming over that timeframe. It does not matter where the CO2 comes from. What you likely mean is that when taking atmosp
