I used #redshift on #xfce and have done so for a few years now.

I set the lat and lon entries in the ~/.config/redshift.conf file to match my rough location, meaning it is now manual rather than automatic. The rest of redshift seems to work fine like that.

I have read elsewhere that you can 'fudge' this by using the 'demo' of geoclue-2 which will provide a rough estimation of location which should be perfectly adequate for redshift purposes - I believe this is done by changing the executable to be `/usr/lib/geoclue-2.0/demos/where-am-i`

@BrodieOnLinux …
4) I really like my #Redshift config and cannot use it with the #Wayland session. The built-in replacement severely lacks features and behaves not how I expect it.

5) The scaling is weird, I cannot set it to the exact same DPI like I have used with my 4K monitor in HiDPI for a decade under X.Org. Everything gets a bit bigger under WL.

6) Why have my mice a whole different acceleration curve under WL?!

If you've ever wondered how it is that we know the distance to our nearby neighbouring galaxies, this is the vid for you.

I found it amazing (though at times it left me behind and I had to go back some) and it answered a question I've long asked but was unable to understantd (not sure why though).

Hab grad die Dämpfer im Redshift Shockstop Vorbau getauscht. Plötzlich kam von der Seite:

"Papaaa? --- Ja? --- Fährst du heute Abend wieder im Dachboden? --- Jep. --- Darf ich dann bei dir oben einschlafen? --- Wieso das denn? --- Ich kann gut bei dir einschlafen wenn du fährst und wieder dieses >Tuhr dä Fronz< guckst."

Hab schon ein leicht schlechtes Gewissen, dass die Tochter Handzeichen, Windschattenfahren und Belgischen Kreisel verinnerlicht hat, aber es in der Schule grad erst so richtig mit Lesen und Rechnen losgeht :o)

<<If the physics of galaxy rotation affects the light that galaxies emit in a manner that is currently unknown, that can also affect the redshift, and therefore can be related to #Alternative #Redshift models.>>

A Glimpse at the New #Redshift Frontier Through Abell S1063: arxiv.org/abs/2411.13640 -> "We report the discovery of five galaxy candidates at redshifts between 15.9<z<18.6 in JWST observations from the GLIMPSE survey. These robust sources were identified using a combination of Lyman-break selection and photometric redshift estimates."

arXiv.orgA Glimpse at the New Redshift Frontier Through Abell S1063We report the discovery of five galaxy candidates at redshifts between $15.9<z<18.6$ in JWST observations from the GLIMPSE survey. These robust sources were identified using a combination of Lyman-break selection and photometric redshift estimates. The ultra-deep NIRCam imaging from GLIMPSE, combined with the strong gravitational lensing of the Abell S1063 galaxy cluster, allows us to probe an intrinsically fainter population (down to $M_{\rm UV}=-17.5$ mag) than previously achievable. These galaxies have absolute magnitudes ranging from $M_{\rm UV}= -17.7$ to $-18.0$ mag, with UV continuum slopes between $β\simeq -2.3$ and $β\simeq -3.0$, consistent with young, dust-free stellar populations. The number density of these objects, log$_{\rm 10}$ ($ϕ$/[Mpc$^{-3}$ mag$^{-1}$])=$-3.43^{+0.28}_{-0.64}$ at $M_{\rm UV}=-18$ is in clear tension with pre-JWST theoretical predictions, extending the over-abundance of galaxies from $z\sim10$ to $z\sim 18.6$. These results, together with the scarcity of brighter galaxies in other public surveys, suggest a steep decline in the bright-end of the UV luminosity function at $z \sim 17$, implying efficient star formation and possibly a close connection to the halo mass function at these redshifts. Testing a variety of star formation histories suggests that these sources are plausible progenitors of the unusually UV-bright galaxies that JWST now routinely uncovers at $z = 10-14$. Overall, our results indicate that the luminosity distribution of the earliest star-forming galaxies could be shifting towards fainter luminosities, implying that future surveys of cosmic dawn will need to explore this faint luminosity regime.

Linux Mint Adding Native ‘Night Light’ Feature to Cinnamon

Linux Mint has revealed it’s brining a native ‘night light’ mode to the Cinnamon desktop. Earlier versions of Linux Mint included a third-party app called Redshift to provide similar functionality. However, when then Mozilla location service was shut down earlier this year, the geo-location capabilities powering Redshift (which made the feature kick-in at sunset for the users location) no longer worked – although the app itself still did. But Linux Mint’s developers felt that asking users to work around the breakage by punching in their location’s longitude and latitude coordinates manually was a tough ask, especially for a distro focused :sys_more_orange:
