kandi X-RAY | BigMap Summary
This package provides you with a big map. It uses Buffer as its storage space rather than heap memory. It implemented by node js pure javascript code (ES6), no other dependencies. Its feature is still relatively simple, and performance worse than build-in Object or Map, but sometimes in order to get more space, we have no other choice. Use Buffer implementation does not exist v8 engine heap memory limit of 1.4GB, you can store 4GB, 8GB or more data therein, as long as sufficient physical memory.

QUESTION
I have created a worldmap using the d3 and now able to create the specific countries to have hover effect , however I have also created the tooltip what I want to do now is to get the country map in the tooltip (the country which is hovered) i have used d3 v4 to do all this.
I have made changes suggested by CodeSmit but it seems I'm missing a lot of things.
...ANSWER
Answered 2021-May-21 at 15:04The .html
method on D3 selections first deletes anything that's already inside those elements before setting the new contents. Thus, to initiate an element's base HTML content with .html
, be sure to call it first before adding anything else to the element, and also do not call .html
later on, or risk it overwriting anything that was added to it.
You're close. You've got a number of issues though.
1. d3-tip Not UsedYou're including the d3-tip library, but you're not making real use of it at all. Because of this, it's adding to the confusion. You have your own
Doesn't Make It Into Tooltip
Your "mouseover" event fails to add the country SVG element for two reasons:
First, because you're selecting the #tipDiv element which never appears since it's part of the d3-tip code that doesn't get used. To fix this, I think you want to select the div.tooltip element instead. Since you already have the 'tooltip' variable set to this, you don't need d3.select; you can simply do:
QUESTION
I've tried a bunch of stuff from the Gatsby docs, and have tried messing with the .js page, nothing wants to work.
Code I want to fetch on client side instead of on build:
...ANSWER
Answered 2021-May-08 at 19:25I actually ended up resolving this with:
import React from "react"; import styles from '../styles/styles.scss' import Header from '../components/header'
export default class FetchObjkts extends React.Component { state = { loading: true, objkts: [] };
async componentDidMount() { const url = "https://staging.api.tzkt.io/v1/bigmaps/523/keys?value.issuer=tz1V9ZviaGUWZjGx4U7cGYFEyUGyqpFnVGXx&active=true"; const response = await fetch(url); const data = await response.json(); this.setState({ objkts: data, loading: false }); }
render() { ... }
Instead of using node for the data, I used useEffect() to fetch from client-side.

QUESTION
I have a constructor that maps the first letter of the words in a text file to all the words that start with that letter and are longer than 3 characters
...ANSWER
Answered 2018-Feb-26 at 05:07Is this what you want?
QUESTION
How would you code a map so that the initial character of each word maps to the full word?
Considering a wordlist that contains:
- albert
- ben
- alice
- cecilia
The output should be {a=[albert,alice], b=[ben], c=[cecilia]}
This is what I have right now but I don't understand how to map each key to all the correspondent words.
The map is of type Map> bigMap;

Answered 2018-Feb-25 at 15:30throws

When a method declares in its signature that it throws
an exception, the caller has to handle it by either rethrowing it back or by catching it.
QUESTION
I have only javascript file that shows osmdroid map source, I used
String[] OSMSource = new String[1];
OSMSource[0] = "https://gps.4u.uz:55443/styles/bright-v9/";
I opened this address, but there is nothing there, but gps.4u.uz is working well.
But I have empty grid, if I use another source, it works. Please, help me what is wrong. My javascript file only redirection, it was not written for me. That is why, it is difficult for me to fix the problem. Here is my file:
...ANSWER
Answered 2017-Sep-02 at 22:48osmdroid, the android library for maps, natively works with the Z/X/Y tile coordinate reference system, which is the same used as
- openstreetmaps.org
- google maps (static tiles)
- bing
- mapquest
- mapbox
- certain USGS sources
- and many more
The url pattern for most of this is nearly universally, http://server:port/path/zoom/x/y.png
See the openstreetmap wiki about what the coordinates mean here: http://wiki.openstreetmap.org/wiki/Slippy_Map
Long story short, the easiest way to solve your problem using osmdroid is the following:
mMapView.setTileSource(new XYTileSource(
"bright-v9",0,22,256,"", new String[]{"https://gps.4u.uz:55443/styles/bright-v9/"}
));
QUESTION
I have a code in which I am trying to execute in parallel.
...ANSWER
Answered 2017-Jul-18 at 17:14There are multiple issues here.
Usingomp_get_num_threads
out of parallel regions
Outside of a parallel region, omp_get_num_threads()
always returns 1
. Use omp_get_max_threads()
instead, it will return the number of threads for any upcoming parallel
region unless manually overridden. Especially threadvec
has only one entry.
Calling gsl_rng_env_setup
in a parallel region won't work properly. Also you are trying to allocate the whole vector of rngs by all threads... Simply remove the parallel region and use omp_get_max_threads()
correctly. Or you could also do:
