    I wasn’t able to read the actual paper since it’s behind a paywall, but it’s not exclusively a TL model. They say this in the abstract:

    Deep space observations of the James Webb Space Telescope (JWST) have revealed that the structure and masses of very early Universe galaxies at high redshifts (⁠z∼15), existing at ∼0.3 Gyr after the BigBang, may be as evolved as the galaxies in existence for ∼10 Gyr. The JWST findings are thus in strong tension with the ΛCDM cosmological model.

    While tired light (TL) models have been shown to comply with the JWST angular galaxy size data, they cannot satisfactorily explain isotropy of the cosmic microwave background (CMB) observations or fit the supernovae distance modulus vs. redshift data well.

    We present a model with covarying coupling constants (CCC), starting from the modified FLRW metric and resulting Einstein and Friedmann equations, and a CCC + TL hybrid model. They fit the Pantheon + data admirably, and the CCC + TL model is compliant with the JWST observations. […] One could infer the CCC model as an extension of the ΛCDM model with a dynamic cosmological constant.



  • The contacts are gold, which definitely doesn’t oxidize any more than solder considering it, y’know, doesn’t oxidize in air at all ever. The solder doesn’t really add any contact surface area, and even if it did, it makes no difference for digital signals. “Better conductivity” doesn’t improve digital sigs either. And why would the contacts ever disconnect?

    I can’t confirm the last paragraph, but HDD manufacturers could just move the PCB closer to the chassis and/or make the contacts’ springs a bit stiffer to achieve the exact same thing, which is slightly more pressure between the contacts. That’s literally all you’re getting here.

    The Systemd init system and its consequences have been a disaster for the human race. It has greatly increased the life-expectancy of those of us who live in “just werks” distros, but it has destabilized GNU/Linux society, has made life unfulfilling, has subjected users to indignities, has led to widespread psychological suffering (in the BSD world to physical suffering as well) and has inflicted severe damage on the Unix world. The continued development of Systemd will worsen the situation. It will certainly subject human beings to greater indignities and inflict greater damage on the Unix world, it will probably lead to greater social disruption and psychological suffering, and it may lead to increased physical suffering even in “just werks” distros.

    The Systemd system may survive or it may break down. If it survives, it MAY eventually achieve a low level of physical and psychological suffering, but only after passing through a long and very painful period of adjustment and only at the cost of permanently reducing users and many other Unix processes to engineered products and mere cogs in the Systemd machine. Furthermore, if the system survives, the consequences will be inevitable: There is no way of reforming or modifying PID 1 so as to prevent it from depriving users of dignity and autonomy.

    If the system breaks down the consequences will still be very painful. But the bigger the system grows the more disastrous the results of its breakdown will be, so if it is to break down it had best break down sooner rather than later.

    We therefore advocate a revolution against the Systemd system. This revolution may or may not make use of violence; it may be sudden or it may be a relatively gradual process spanning a few decades. We can’t predict any of that. But we do outline in a very general way the measures that those who hate the Systemd system should take in order to prepare the way for a revolution against that form of society. This is not to be a POLITICAL revolution. Its object will be to overthrow not distros but the init-system basis of the present GNU/Linux ecosystem.
