There is a great article from the German Meteorological Service on WeatherNext 3 and how AI-based weather models will probably co-exist with physics-based ones.

I've been working on and off for many years on my own weather app mainly to learn Swift/ SwiftUI. Forecasts come from national and international weather institutes via https://open-meteo.com/ but I am running my own server component that ingests data from NOAA, MSC, DWD, EUMETNET, CWA, and more for radar-based rain alerts, weather alerts, and my own map layers for the app (radar, temperature, precipitation, radar, pressure, wind, ...). It's based on open and free data and all features will be free to use on release date. I have no intention of making money with this, just something I personally like to use.

Most features are available in NA and EU by now so if this feels remotely interesting, feel free to download. Friends and family tell me it's miles better than what they were using but feel free to check if out and give me some feedback :)

Purelymail is really good. I've been using it for over 4 years now and haven't had any issues around deliverability or availability. It might not be fancy but it has almost any feature you'd want.

New comment by witweb in "Unlearning perfectionism"

witweb — Sat, 05 Feb 2022 18:33:27 +0000

Great article, in which I find myself partially. I have tried for many years to be quite perfectionistic but mostly because of the feeling of not being good enough. It's a pretty destructive behavior as you're always anxious and imagining the worst. At some point at university, I was able to slowly discard this behavior, although this development is certainly not over yet. What helped me most were good friends and a part-time job in a consulting firm, which I absolutely hated btw. But overall I learned to focus more on the important things and generally to care less. I'm generally happier with my work and don't let setbacks get to me as quickly. Rather, I take them as a challenge to become even better. (Starting my first job as an engineer after university soon btw! :))

New comment by witweb in "Proof-of-Stake and Stablecoins: A Blockchain Centralization Dilemma"

witweb — Mon, 29 Nov 2021 23:53:51 +0000

I don't really get your point here as you don't have to buy ASICs every X years with PoW consensus. A friend of mine mines with his 3070 in a mining pool and makes a small plus with it. Hell, you can even mine with a 7 year old PC. Will you ever find a block? Probably not, but you're still securing the network and may get lucky. I don't see how this incentivizes centralization any more than PoS. With PoS, you have to be part of the network by spending money on a token while with PoW, you just need an existing PC with some compute power.

Is the efficiency really that depend on the architecture (x86 vs arm64)? I always thought Apples lead comes from things like the little big approach and the lower transistor size. Can someone elaborate?

DIDs are not meant to compete with ENS addresses. They solve different problems.

witweb — Tue, 22 Jun 2021 19:45:08 +0000

But what would be the solution? I've already played around with DIDs and Verifiable Credentials in the SSI-context and I like it from a tech perspective. I am also not sure if the spec should be held accountable to potential privacy misuses – the user should be. Additionally, you don't have to use the big tech solutions. The tech is inherently open, just look at the many DID methods.

But what I am concerned of are consortium (identity) networks like Sovrin which are run by a hand full of companies. At least in Germany, the government is starting to like what they are doing which is horrible imo. The identity layer of a state should not be governed by a consortium of private companies, no matter what fancy governance model they have.

Please read up on UASF and Bitcoin. People can buy tons of mining factories, but if a very large amount of nodes start rejecting blocks and therefore the rewards, miners start to rethink their stance very fast. There is no discussion here, history proves it.

witweb — Wed, 03 Mar 2021 08:10:22 +0000

So people living in countries without a stable currency due to hyperinflation don't count as a real use case? It's sometimes the only way they can secure their capital. I think that we need to think outside of our elitist western bubble more often. Not all people live in a stable democracy with (semi-)stable currencies.

But what's going to happen with the nuclear waste? I've heard too many times about water getting into permanent repositories and leaking containers contaminating the biosphere. Seems like a bad idea to me...

There is no Bitcoin Core! There is only one Bitcoin using Bitcoin Core as one of its clients used to connect to the Bitcoin blockchain. The rest are just irrelevant forks.
