The only time Hacker News is this interested in Bitcoin is when there's a bubble forming Sun 30 July 2017 You might have got the impression that there are a lot of Bitcoin-related posts on Hacker News lately. With SegWit set to activate in the next few weeks, and Bitcoin Cash likely to fork off on the 1st of August, I took a look at Hacker News' relationship with Bitcoin over the past years.

The EU Proposes New Rules to Govern the European Space Race

wired.com Fernanda González 2025-08-12 09:00:00

There are around 11,000 satellites orbiting Earth, and it is estimated that at least 50,000 more will be launched in the next decade. There are also exploration instruments, resupply vessels, and complexes like the International Space Station. But who regulates all this activity in space? In the absence of clear regulations, the European Union has proposed the Space Act, a set of measures that seeks to make the European space sector a cleaner, safer, and more competitive environment, both domest

Bitcoin enthusiasts have been perplexed lately. Why is the price so stagnant, even with all the hype created by guys like President Donald Trump? The White House has largely been seen as enacting a pro-crypto agenda and even got its first crypto czar in David Sacks, after all. You’d think prices would be soaring. Well, there’s a simple answer, according to a new report from Bloomberg News. And the average, non-wealthy crypto trader probably isn’t going to like it. According to Bloomberg, the lo

Properly seeding random number generators doesn't always get the attention it deserves. Quite often, people do a terrible job, supplying low-quality seed data (such as the system time or process id) or combining multiple poor sources in a half-baked way. C++11 provides std::seed_seq as a way to encourage the use of better seeds, but if you haven't thought about what's really going on when you use it, you may be in for a few surprises.

Changing one gene can restore some tissue regeneration to mice

Regeneration is a trick many animals, including lizards, starfish, and octopuses, have mastered. Axolotls, a salamander species originating in Mexico, can regrow pretty much everything from severed limbs, through eyes and parts of brain, to the spinal cord. Mammals, though, have mostly lost this ability somewhere along their evolutionary path. Regeneration persisted, in a limited number of tissues, in just a few mammalian species like rabbits or goats. “We were trying to learn how certain anima
