The author does indeed do that via their definition of the volume equivalent sphere radius r_s.

The same happened to the Toronto Public Library around the same time, probably coincidence rather than connected. It has made me reflect on the breadth of non-traditional public se…

I'd definitely like to second how great peewee is. It's been a core part of running our telescope for the last 8 years. It strikes a nice balance between power and simplicity, a si…

If you happen to use `iTerm2`, then https://github.com/daleroberts/itermplot works very well. I've used it before and can recommend it pretty highly.

I imagine you'll kick yourself for not figuring this one out. It means homepage (constructed from hejmo = home, and pago = page)

I have bursts of progress trying to learn Esperanto, also with Duolingo. I guess the unfortunate aspect of Esperanto is that you don't meet a lot of other learners in real life so …

Actual research astronomer here, and as a (radio) astronomer I would love to get rid of leap seconds. Assuming that UTC = UT1 (the time measure based on Earth rotation) is not accu…

Backing up my gmail has been on my list for a while (as step 1 of a migration away from gmail). Does anyone haver any experience with this tool, and could compare it to offline-ima…

That's a great description.

Sounds like you moved from one nice system to another! I pretty much moved over to a 12.9" iPad Pro + Pencil when they first came out. It replaced my "system" of doing derivations …

I'd like to add a bit of love for the timeless classic, the Bic Cristal. Reliable and consistent, and sufficiently cheap you can have them scattered all over home and office so the…

Thanks, that's good to hear! I'll give it another look next time I look at switching things up.

I've tried to use Zotero over the years, and I always stumble with it because it didn't have a good handling of arXiv id's. The arXiv is one of the primary way of finding papers in…

The GP is making a completely legitimate point here that broad sharing of large raw datasets is pretty hard, but I don't think anyone is arguing we should give up. Here's a few tho…

Cylinders are great in a sense. As you say the efficiency is awesome, but the standing waves make life complicated! The GPU boom is causing big issues. Future projects are targeted…

Unfortunately cosmology and astrophysics is basically all passive measurements. Doing a controlled experiment would be more useful, but would probably remove half the fun!

Just commenting to say that I work on this project. So let me know if anyone has any questions about it!

I'm a big fan of pyinstrument. Many of the newer profilers, (e.g. py-spy) attach to a process externally via SYS_PTRACE and though that seems great in many ways, it is very much a …

Oh, that's interesting. ESA says they distribute the Sentinel data free of charge as far as I can tell. So I guess the issue is that you'd need to download and host the data yourse…

Can you use ESA Sentinel satellite imagery as an intermediate step? It's 10m ish resolution updated on a roughly weekly cadence. I use it frequently (via https://apps.sentinel-hub.…

I mean, I sit around wearing headphones a lot, but that's about the closest it gets I'm afraid :)

Yeah, that's definitely one of the main hypotheses. There aren't any other repeating FRBs known to do this yet, so how general a mechanism this is, is not known.

There is some possibility of gravitational lensing of FRBs and people are definitely searching for it. However, in this case it is refraction caused by variation in the density of …

Good question. For many FRBs there is access to the original antenna time streams (which are essentially voltages samples at 800 MHz), so superficially that might give you 1.25ns r…

To be slightly fair, the policies of the journals have a lot to do with this. I'll try and explain: This paper was submitted to Nature as it would be fairly high profile, and Natur…
