There is KDEConnect, which has apps for all major platforms (iOS, android, macOS, Windows and of course Linux) and some more. I even used between Apple devices when AirDrop did not work for some reason.
MagicEarth (which seems to be a MagicLane product; https://www.magicearth.com/) is my daily driver navigation app. I prefer it over Google maps for everything routing related. The only thing Google is better at is showing me relevant metainformation about places (when is this restaurant open? What is this doctor's telephone number and website?), and that's the only reason I'm keeping maps on my phone.
I wish, but like I said below, it's not developped anymore. The company got bought by the french cloud company OVH. There are multiple complaints of stale OSM data in the github issues.
Let's hope they want to make a public and open source map part of their europaen google alternative.
It’s a bit unintuitive, but IIRC you need to go into the settings and tell it to download the card art. Two reasons for this: 1, copyright and 2, it’s a big download if you get them at full quality.
Thanks, I found it in the 'Content Downloaders' menu!
It estimates the download time to 6 hours, and it's not because of the size but most likely their server works slowly. And in the meanwhile it does not let you play, well tomorrow then :)
Later, in 2019, a 795 bit key was factored with CPU time that "amounted to approximately 900 core-years on a 2.1 GHz Intel Xeon Gold 6130 CPU. Compared to the factorization of RSA-768, the authors estimate that better algorithms sped their calculations by a factor of 3–4 and faster computers sped their calculation by a factor of 1.25–1.67."
So assuming the better algorithms transfer to smaller numbers, someone who knows how to use them (factoring big numbers seems significantly harder than just running CADO-NFS and pointing it at a number and a cluster) could probably do it in a couple months on a couple dozen modern machines.
For example, using the "795-bit computations should be 2.25 times harder than 768-bit
computations" from the publication accompanying the second factorization, we could assume 900/2.25 = 400 Core-years of the Xeon reference CPU (which is 6 years old by now) would be needed to break the smaller key with the modern software. Two dozen servers with 64 equivalently strong cores each would need slightly over 3 months. Not something a hobbyist would want to afford just for fun, but something that even a company with a moderate financial interest in doing could easily do, provided they had people capable of understanding and replicating this work.
I assume there is some reason why the past factorizations weren't done with GPUs. It could be just lack of a good implementation and insufficient numbers of people interested in the topic, but it could also be something about the algorithm not being very suitable for GPUs.
CUDA only had its initial release in 2007 (compared to the mentioned crack in 2009), and I remember it being a fairly limited product at that point. GPUS were also much slower back then.
If anyone is interested the whole series can be watched on Youtube for free. Altogether it is not that great, nevertheless I find the meta story about the pilot fascinating (a show about conspiracy theories "predicts" the 9/11 attack).
You can watch it as two shows (like a lot of shows from the 26 episode season era), one being the story arc episodes and two being the monster-of-the week style episodes.
