kandi X-RAY | geo Summary
Databases of events at specific times occurring at specific places on the earth’s surface are likely to be queried in terms of ranges of time and position. One such query is a bounding box query involving a time range and position constraint defined by a bounding lat-long box. The challenge is to make your database run these queries quickly. Some databases may either not support or suffer significant performance degradation when large datasets are queried with inequality conditions on more than one variable. For example, a search for all ship reports within a time range and within a bounding box could be achieved with a range condition on time combined with a range condition on latitude combined with a range condition on longitude ( combined with = logical AND). This type of query can perform badly on many database types, SQL and NoSQL. On Google App Engine Datastore for instance only one variable with inequality conditions is allowed per query. This is a sensible step to take to meet scalability guarantees.

QUESTION
I am using the following code to retrieve the html code from a url. It is working fine for a url as:
- https://trends.google.com/trends/?geo=US However, not working for the following one, returning an error as
"The remote server returned an error: (429) unknown.'"
What could be the error or how to get more info about the error?
...ANSWER
Answered 2021-Apr-13 at 19:44It's no longer possible to get the source code of google services without an API because specifically the trends service makes many calls when you visit only trends.google.es/trends/explore?q=test hence the error 429.
Do not waste your time digging in proxies, browser emulation or bots none will work. The best way is to use Google API for c# .

Edit: It looks like this is a known issue with the "cascade" method. Results that return NA values after the first attempt don't like being converted to doubles when subsequent methods return lat/lons.
Data: I have a list of addresses that I need to geocode. I'm using lapply()
to split-apply-combine, which works, but very slowly. My thought to split (further)-apply-combine is returning errors about dim names and sizes that are confusing to me.

ANSWER
Answered 2021-Jun-13 at 12:54When having issues like this you should start by checking two things:
First whether the css file that is being loaded actually includes your rules, because your browser may have a cached version stored and simply avoids loading it again.
If that is ok, then you should check whether or not your rules are being overwritten by any other rule included, that may be more specific or flagged as!important
The web inspector can help in both cases!

When I'm doing activity from a user in a project, I get the instant location and save it with firebase and firestore. But when I call back the query, I get everything I saved in the list. I just want it to come as an index index. For example 1-"kosum1". How can I do that?
...ANSWER
Answered 2021-Jun-13 at 10:59You can convert the List
to a Map
of its index to the list value using the List.asMap() method.
The map uses the indices of this list as keys and the corresponding objects as values.

QUESTION
I want to use the elasticsearch Geo-polygon query (https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-geo-polygon-query.html) or Geo-shape query inside an ingest pipeline and I've been thinking how to do it - as there is no such processor as query processor
and the example for the geo polygon is with this type of query.
The reason for me trying to use this tool is to enrich documents which's country location is null
, by checking their lat
and lon
fields and determining which country the doc is from.
Is there anyway this could be done in an ingest pipeline? Or any other way to determine a position by lat and lon within geo shapes in a pipeline?
...ANSWER
Answered 2021-Jun-12 at 07:49Answer for enrichment of the data with geo-based policy: https://discuss.elastic.co/t/geo-polygon-query-inside-ingest-pipeline/274886/9
Also note that there is a feature suggestion pending in Elastic Github in order to exclude the geo-shape used for the enrichment, so there will be no need for a second pipeline to delete the field.

Whenever I fetch data from any server to display it in ag-grid, ag-grid does not maintain the column order for the column that uses valueGetter to choose the value and puts that column automatically at the end.
The problem is replicated in the following code sandbox link: https://codesandbox.io/s/ag-grid-column-ordering-bug-bz055 as a minimum reproducible example
The data received from the server is in the following format
...ANSWER
Answered 2021-Jun-11 at 14:48Since the column does not have a field
supplied, I'd recommend either supplying a field
or colID
to the column. This would be the simplest approach without having to use any API calls to move the column:

I would like to create a loop in which the index is given by the column names of a dataframe. The idea is to select one column at a time and create a map based on the data in that column. I need i
being the column name, as it identifies the name of the variable and I'll use that as part of the title of the map. However, I do not seem to be able to associate my index i
to the name of the column. My code goes as follows:
ANSWER
Answered 2021-Jun-10 at 10:55In base R, you can either select the columns by position or by name, you can't combine them both in one command. If you use dplyr::select
you can select columns by name and position in the same command.
So here are your options -
