QUESTION
As I'm trying to import JSON file on PostgreSQL pgadmin, I wrote following script, but it didn't work with the error shown below, for some reason.
The sql/plpgsql:
...ANSWER
Answered 2021-May-24 at 03:00After some tryings, as @jjanes mentioned, I found the cause of this problem, it was beucase an empty line in the end of the json file (tmp03.json).
As I copy and pasted to the file using "cat > file" and I inadvertently pressed one unnecessary enter key in the end of the lines, it resulted creating a empty line in the end of the json file. So, this line caused the error. sigh..
Here some extra tryings I made for further understanding around this issue.
- tmp05.json, lines of json with removed last "empty" new line
worked
- tmp03.json, lines of json with an empty line in the last (the question mentioned error)
QUESTION
I have a large table with a comments column (contains large strings of text) and a date column on which the comment was posted. I created a separate vector of keywords (we'll call this key) and I want to count how many matches there are for each day. This gets me close, however it counts matches across the entire dataset, where I need it broken down by each day. The code:
...ANSWER
Answered 2021-Apr-21 at 18:50As pointed out in the comments, you can use group_by
from dplyr
to accomplish this.
First, you can extract keywords for each comment/sentence. Then unnest
so each keyword is in a separate row with a date.
Then, use group_by
with both date and comment included (to get frequency for combination of date and keyword together). The use of summarise
with n()
will give number of mentions.
Here's a complete example:
QUESTION
This is my first time using GCloud DNS, looking to configure a public zone for Hodl.Art. Opted for GCloud because their DNSSEC supports RSASHA256 (GoDaddy doesn't, nor the rest of my registrars), compatible with ENS.Domains for renaming a digital wallet.
My problem is that, try as I may, GCloud doesn't want to publish/make-public my A and TXT record sets. The zone currently looks like this in the console but no resolution!?
Am I overlooking something obvious or need to turn on some other functionality?
...ANSWER
Answered 2021-Mar-25 at 00:58If you are using the @
as the origin, for Google Cloud DNS leave the entry field blank.
QUESTION
I'm creating a blog in React to be deployed on GitHub Pages.
Problem
- Created my React app and added BrowserRouter for navigation, everything was working fine on localhost and the app successfully deployed on the GitHub Pages.
- Even though Home page was accessible on GitHub Pages, if I click on any link there was 404 Error. The problem was BrowserRouter does not work with GitHub pages.
- After some research I added HashRouter in my react app as BrowserRouter was not working on GitHub pages.
- With HashRouter again Homepage is loaded successfully but if I click on link that should take me from home to blog section the expected behaviour should have been something like this
localhost:3000/#/blog
but the url changes to something likelocalhost:3000/blog#/
and I'm still on homepage. - Problem 4 is true for both localhost as well as Github Pages
But if I manually enter the url
localhost:3000/#/blog
it works perfectly fine and loads the Blog component as expected. Similar behaviour on the GitHub Pages.Home.js

QUESTION
I think this should be relatively easy but I'm a noob!
Need to return results in a new pandas column (call this column B) that is based on the result of the below row in column A.
Please print the below code
...ANSWER
Answered 2019-May-05 at 12:49numpy.select & Series.shift
We can use numpy.select
for this so we can define multiple conditions and based on those conditions we can assign values to your new column B.
In our conditions we use Series.shift
which we use so we can check if the next value is SELL
or BUY
.
Series.eq
is the same as using == 'SELL'
for example
Note I reverse your dataframe, since you want to apply the logic from the bottom up, I do this with df[::-1]
. Which is the same method to reverse a list in Python.

QUESTION
I didn't add any data to my RecyclerView but it shows a empty box (the one I styled in the layouts for my data) anyways. It crashes with this errormessage
...ANSWER
Answered 2017-Nov-20 at 16:41These are issues with calculating the index in RecyclerView:
In getItemCount it should be + 1, instead of + 2, as it only needs to add one additional item for add button.
In getItemViewType position at the end of the list if list length, rather than list lenght +1. This is because position is 0-indexed. So, for example, if you have 5 items, positions 0-4 will be your exercise items, and then position 5 (position == exerciseList.size) will be an add item.
Adding logs in getItemViewType for position and generated view type is helpful for debugging, as it shows which positions are calculated incorrectly very quickly.
