kandi X-RAY | ciel Summary
A GraphQL library for querying smart contract events. Check out this Twitter thread documenting the experiment. You can interact with the Database contract here using Pragma (it's on the Rinkeby network). The gas limit suggested by Metamask is usually around 40K gas while I found that usually around 26K is used. Still too expensive for my taste, I'll see how I can optimize this but the high cost is probably due to the use of string variables which are more expensive on the blockchain.

QUESTION
I have a column named "Trip", in which I have infos such as the hotel, country, and type of trip. The thing is these infos are hand typed, so sometimes instead of typing "HOTEL ABC", the person entering the infos simply enters "ABC", or event "HTL ABC". Also, ABC can also refer to a country.
What I want is to extract all hotel names on each cell. Here's the function I created, but I can't get it to work. (Y2 is the TRIP Column)

Answered 2021-Mar-26 at 18:47- You are missing semicolons before "CORAIL NOIR" and "LOHARANO" .
- You need to remove the final semicolon after "FRIDAY ATTITUDE" because
IFS expects all arguments after position 0 to be in pairsand the final semicolon makes Google Sheets think another set of arguments is coming. - You can help yourself out with future troubleshooting by spacing out your function better - eg the following will still work when pasted into Google Sheets:

I am fairly new to react, I am developing a component that will get data from a local JSON file and output it on to a table component.
I am currently stuck on a loading screen, I am getting the following error, Uncaught (in promise) SyntaxError: Unexpected token < in JSON at position 0

QUESTION
I am trying to obtain an ortographic projection of the celestial sphere, with equatorial coordinates, as seen from a certain latitude, as in the following picture:
(Grid obtained from Skychart/Cartes du ciel)
This image is a print of Skychart/Cartes du ciel, showing the equatorial grid for an observer at 23°S latitude. I want to be able to reproduce the exact same image in Python (apart from the dark blue background). My first attempt was to use CartoPy, setting the central latitude as -23, as follows:
...ANSWER
Answered 2021-Feb-24 at 07:43First of all, your first image is Azimuthal Equidistant Projection. So that, it is quite different from your second plot (Orthographic projection). To get the plot (first image) like that using Cartopy requires some steps that are interesting to follow. Here is the code with comments that produces the output plot that I consider a good result.

I'm exploring the possibilities of the magnificent software Skyfield by Brandon Rhodes. I've made a script to calculate conjunctions in Right Ascension between random objects. I use the following script:

Answered 2020-Jul-10 at 11:53Good question! I should add a new section to https://rhodesmill.org/skyfield/searches.html explaining this common behavior seen when subtracting two longitudes or right ascensions. The key to unraveling the mystery is to watch what happens to the angle difference at one of the moments that is showing up in your output as a phantom conjunction. I’ve attached a script which prints this for the very first event you print, between Venus and Aldebaran:

Once items() is sorted, you just have to convert that back to a dict and sort the values:
