skyheadlines.com Carbon Molecule In Space Detected By James Webb - Sky Headlines

NASA's James Webb Space Telescope have Found Carbon Molecule in Space. Let's have a keen glance at the research findings.

> For the first time ever in space, scientists discovered a novel carbon molecule known as methyl cation (CH3+). This molecule is significant because it promotes the synthesis of more complex carbon-based compounds.

> Early galaxies' stars allowed light to travel freely by heating and ionizing intergalactic gas, clearing vast regions around them. > > Cave divers equipped with brilliant headlamps often explore cavities in rock less than a mile beneath our feet. It’s easy to be wholly unaware of these cave systems – even if you sit in a meadow above them – because the rock between you and the spelunkers prevents light from their headlamps from disturbing the idyllic afternoon. > > Apply this vision to the conditions in the early universe, but switch from a focus on rock to gas. Only a few hundred million years after the big bang, the cosmos was brimming with opaque hydrogen gas that trapped light at some wavelengths from stars and galaxies. Over the first billion years, the gas became fully transparent – allowing the light to travel freely. Researchers have long sought definitive evidence to explain this flip. > > New data from the James Webb Space Telescope recently pinpointed the answer using a set of galaxies that existed when the universe was only 900 million years old. Stars in these galaxies emitted enough light to ionize and heat the gas around them, forming huge, transparent “bubbles.” Eventually, those bubbles met and merged, leading to today’s clear and expansive views.

Downsides of Flatpak
  • When I was packaging Flatpaks, the greatest downside is

    No built in package manager

    There is a repo with shared dependencies, but it is very few. So needs to package all the dependencies... So, I personally am not interested in packaging for flatpak other than in very rare occasions... Nix and Guix are definitely better solutions (except the isolation aspect, which is not a feature, you need to do it manually), and one can use at many distros; Nix even on MacOS!

    The hardest scaling issue by Codeberg (a nonprofit, free software platform/service for code hosting)

    blog.codeberg.org The hardest scaling issue — Codeberg News

    If you want to know more about our current technical scaling issues: Rest...

    cross-posted from c/softwareengineering@group.lt: https://group.lt/post/44632

    > This kind of scaling issue is new to Codeberg (a nonprofit free software project), but not to the world. All projects on earth likely went through this at a certain point or will experience it in the future. > > When people like me talk about scaling... It's about increasing computing power, distributed storage, replicated databases and so on. There are all kinds of technology available to solve scaling issues. So why, damn, is Codeberg still having performance issues from time to time? > > ...we face the "worst" kind of scaling issue in my perception. That is, if you don't see it coming (e.g. because the software gets slower day by day, or because you see how the storage pool fill up). Instead, it appears out of the blue. > > The hardest scaling issue is: scaling human power. > > Configuration, Investigation, Maintenance, User Support, Communication – all require some effort, and it's not easy to automate. In many cases, automation would consume even more human resources to set up than we have. > > There are no paid night shifts, not even payment at all. Still, people have become used to the always-available guarantees, and demand the same from us: Occasional slowness in the evening of the CET timezone? Unbearable! > >I do understand the demand. We definitely aim for a better service than we sometimes provide. However, sometimes, the frustration of angry social-media-guys carries me away... > > two primary blockers that prevent scaling human resources. The first one is: trust. Because we can't yet afford hiring employees that work on tasks for a defined amount of time, work naturally has to be distributed over many volunteers with limited time commitment... second problem is a in part technical. Unlike major players, which have nearly unlimited resources available to meet high demand, scaling Codeberg's systems...

    TLDR: sustainability issues for scaling because Codeberg is a nonprofit with much limited resources, mainly human resources, in face of high demand. Non-paid volunteers do all the work. So needs more people working as volunteers, and needs more money.
