Nice talk about the Gauribidanur Radio Observatory building a simple all-sky 1-bit digitization system that allows to create beams a posteriori…

The prototype system Motivation: Observations of Pulsars and other astrophysical transients below 100 Miz is still largely uncharted territory. - Pulsar observations below 100 MHz are necessary to understand their emission mechanism, and phenomena like spectral turn-over. - Great tool to probe the ISM- effects more prominent at low frequencies - Fast Radio Bursts: Astrophysical mystery! Have been detected at 120 MHz [ Pastor-Marazuela, 2021] and 111 MHz [Z. Pleunis, 2021] : Possibility to detect at even lower frequencies! Goal: Establish a dedicated radio telescope operating below 100 MHz at the Gauribidanur Observatory using Log-Periodic Dipole antennas (LPDA)

Bela Dixit is talking about the upgrades to the Finnish Metsahovi radio telescope. Many similarities to our upgrade, but for a single dish system.

Very nice talk on LOFAR rebuilding of their control system, all based on open source components, including PyTANGO as SCADA.

Lots of emphasis on observability!

Very interesting couple of slides from the NOEMA presentation: compared to 20 years ago, only 4 sub-millimeter arrays remain.

@GottaLaff not sure how the line of questioning that demonstrates “Trump organization surely employs a lots of crooks” can go well with the Jury…

The IRAM 30m was inaugurated 40 years ago! 6000h/year of observing time!

So, it’s time for an upgrade…

Miguel Sánchez-Portal said that they’ve been closed for 11 months for this upgrade, plus 2-3 months for the surface repainting.

Radio Astronomy in Spain started with the host-country time observations from Riu et al. (University of Barcelona) of a radio source occulted by the moon.

Quick ranking of the new iPad Pro set in terms of “ooh, this is notably better than the thing that came before”

  1. Magic Keyboard - markedly better…like really better

  2. iPad Pro - OLED is slick

  3. Pencil Pro - squeeze to bring up markup tools is cool, but basically the same otherwise so far

@matt what about the dynamic shadows? Those look helpful and neat…

juandesant,
@juandesant@astrodon.social avatar

@matt when you hover on an application using PencilKit, a shadow is digitally formed that reflects both the tool and its orientation on M4 iPad Pro… see for instance https://mastodon.social/@b3ll/112453001360323961

I think there is a lot of truth to this: before algorithms, we depended on serendipity and curation, and both meant interacting with humans. The more the algorithm got in, the less space for fun, and the more incentive to gaming the algorithms.

Linux question:

In bash, I can write:
(cd .. && ls)
and it will run "ls" in the parent directory, but after the command executes I will not have CD'd. The CD is confined in the subshell in the ().

If I try this same command in the alternate shell "fish", it prints the error "command substitutions not allowed here" and nothing is executed. Is there a fish equivalent of "run this single line of commands in a rubber-room subshell whose variables and pwd do not escape"?

juandesant,
@juandesant@astrodon.social avatar

@mcc just tested in iSH after installing fish with apk add fish:

localhost:~# fish -c "ls"  
juandesant.rss  
localhost:~# fish -c "echo $(fish -c ls)"  
juandesant.rss  
localhost:~# fish -c "$(fish -c ls)"  
fish: Unknown command: juandesant.rss  
fish:   
juandesant.rss

juandesant.rss is the only file in that directory.
