GPS-free navigation nears actuality with quantum know-how breakthrough


In a nutshell: At the moment’s typical navigation-grade movement sensors are concerning the measurement of a grapefruit, serving to steer ships, planes, and automobiles at the side of GPS indicators. This implies they at all times want satellite tv for pc connectivity to perform, however a brand new breed of ‘quantum compass’ may finally allow us to ditch the satellites totally.

The thought of utilizing quantum know-how for navigation is not precisely novel. The method depends on sensors referred to as atom interferometers that may observe place and movement with none want for GPS satellites. However the issue was that to get the required navigation precision, it needed to be monstrously big to carry six massive atom interferometers – sufficiently big to fill a complete room. Nevertheless, that is altering.

A workforce at Sandia Nationwide Labs has developed ultra-compact optical chips that may energy these quantum navigation sensors in a package deal sufficiently small to stay principally wherever. It is all about changing the cumbersome laser programs usually wanted for the atom interferometers with tiny built-in photonic circuits.

The scientists say that lowering dependency on GPS is necessary as a result of satellite tv for pc indicators may be disrupted or spoofed. This may trigger main complications for army operations or automated transport programs.

“By harnessing the rules of quantum mechanics, these superior sensors present unparalleled accuracy in measuring acceleration and angular velocity, enabling exact navigation even in GPS-denied areas,” mentioned Sandia scientist Jongmin Lee.

One key piece they developed to attain all this can be a modulator that may exactly management and mix a number of laser frequencies from one supply, eliminating the necessity for stacking particular person lasers.

Along with being extra compact, the chips are additionally extra sturdy in opposition to vibrations and shocks. That ruggedness may enable deploying the quantum sensors in all types of difficult environments that will wreck in the present day’s fashions.

Then there’s the fee issue. These room-sized quantum navigation programs aren’t simply bodily big; they’re vastly costly, too: a single laser modulator can run over $10,000. However by utilizing semiconductor manufacturing to supply their chips en masse, the Sandia workforce hopes they’ll drive prices means down to spice up affordability.

“We will make tons of of modulators on a single 8-inch wafer and much more on a 12-inch wafer,” mentioned Sandia scientist Ashok Kodigala.

These purposes may additionally prolong far past simply navigation and GPS backups. The workforce is exploring utilizing the quantum sensors to detect refined gravitational adjustments for mapping underground sources and constructions. The compact optical chips have promising potential in areas like LIDAR, quantum computing, and optical communications, too.

The findings had been important sufficient to be revealed as the duvet story within the journal Science Advances.

Learn how to Override Strategies in localStorage? | by Sabesan Sathananthan


Use localStorage with JavaScript.

I typically wish to rewrite localStorage to implement a sure operate. What are the strategies to rewrite the strategies in localStorage? There are various builders who wish to rewrite the strategies in localStorageto understand the expiration time of the important thing, or to watch the learn and write of the important thing. So what are the strategies to override the strategies in localStorage. That is my forty third Medium article.

Many builders like the concept of ​​rewriting, first conserving the unique technique after which rewriting the strategy instantly on localStorage like beneath.

Nevertheless, this fashion of writing is just not overriding the strategy setItem(), however so as to add a setItem attribute to localStorage. When the worth attribute of the strategy is asserted, the native setItem() technique is overwritten.

I haven’t examined it an excessive amount of, however in some browsers, this attribute will likely be ignored and inflicting our rewriting to fail.

If we glance carefully, setItem and getItem are inherited from Storage __proto__ pseudo property.

Then we instantly override the above localStorage.__proto__ technique.

This implements the true override of the setItem() technique.

However there may be nonetheless an issue right here. Each localStorage and sessionStorage inherit from Storage. After rewriting the properties or strategies on localStorage.__proto__, the strategies in sessionStorage are additionally rewritten.

We don’t instantly modify the strategy of localStorage itself, however wrap a layer on the skin, after which use localStorage to understand the storage operate on the backside layer.

On this approach, the diploma of freedom is comparatively greater, and there’s no compatibility downside in Part 1. Solely the identify used has modified and the properties and strategies in localStorage are fully blocked.

If you wish to use a customized object with out the pack then you’ll want to implement all of the properties and strategies. It’s not doable to mock a way alone just like the above.

Use Object.definePropertyor Proxyequal to fully overriding the localStorage variable. Higher than Part 3 in that the identify has not modified.

4.1 Direct protection, no impact

For those who use the next technique to cowl instantly, it would haven’t any impact.

We get the property descriptor of localStorage by Object.getOwnPropertyDescriptor. It may be discovered that there isn’t a writable: true attribute, which signifies that localStorage is just not instantly writable.

4.2 Overriding with Object.defineProperty

Since there isn’t a writableattribute, we’ll add one to it. We are able to override localStorage with Object.defineProperty.

However you’ll be able to’t use the above writing technique with one layer exterior. For those who instantly give the above myLocalStorage to localStorage then it would generate infinite recursion (to keep away from deceptive, the improper writing technique is not going to be written right here).

I’ve made a backup of localStorage right here. For those who want a local technique then you too can function it.

On this article, we don’t particularly implement a operate equivalent to setting the expiration time. However speak about how you can rewrite localStorage or the strategies in it from one other perspective.

How you can Add a Header to a curl Request

curl is a type of nice utilities that is been round seemingly ceaselessly and has infinite use circumstances. As of late I discover myself utilizing curl to batch obtain recordsdata and check APIs. Generally my testing leads me to utilizing totally different HTTP headers in my requests.

So as to add a header to a curl request, use the -H flag:

curl -X 'GET' 
 'https://nft.api.cx.metamask.io/collections?chainId=1' 
 -H 'settle for: software/json' 
 -H 'Model: 1'

You possibly can add a number of headers with a number of -H makes use of. Header format is normally [key]: [value].

Java maven – IllegalArgumentException: Enter have to be set


I received virtually equivalent console output as what you shared above. A sure check of mine wouldn’t even run step one, which advised me it had one thing to do with my ‘DriverUtils’ or my ‘Hooks’.

The start of my characteristic file:


@ProdSmoke @TC1.38 @ARCCP-T138 @TestCaseKey=ARCCP-T138
Situation: Person logs in, clicks important buttons, logs out, logs in, logs out

    # navigate to PROD CLIENT PORTAL
Given person navigates to "https://our-website-url.com/login"
And person has entered legitimate prod username and legitimate password

My Hooks file regarded like this:


import api.companies.AuthenticationControllerService;
import context.SharedContext;
import io.cucumber.java.After;
import io.cucumber.java.Earlier than;
import io.cucumber.java.Situation;
import io.restassured.RestAssured;
import io.restassured.response.Response;
import utils.CommonMethods;
import utils.ConfigReader;
import utils.DriverUtils;

public class Hooks {
    non-public static String authorizationToken = "";
    AuthenticationControllerService authenticationControllerService = new AuthenticationControllerService();
    @Earlier than("@UI")
    public void setUp() {
        ConfigReader.initializeProperties();
        DriverUtils.createDriver();
    }
    @Earlier than("@API")
    public void setupBaseURIGetToken(){
        ConfigReader.initializeProperties();
        RestAssured.baseURI = ConfigReader.getProperty("authorization.url");

        Response authResponse = authenticationControllerService.authorizeAdmin(RestAssured.baseURI);
        String responseBody = authResponse.getBody().asString();

        authorizationToken = authResponse.jsonPath().getString("token");
        System.out.println("Authorization token: " + authorizationToken);

        SharedContext sharedContext = SharedContext.getInstance();
        sharedContext.setAPIAuthToken(authorizationToken);
        sharedContext.setResponseBody(responseBody);
    }
    public String getAuthToken(){
        return authorizationToken;
    }

    @After("@UI")
    public void cleanUp(Situation situation) throws InterruptedException {
        if (situation.isFailed()) {
            situation.connect(CommonMethods.takeScreenshot(), "picture/png", situation.getName());
        }
        CommonMethods.takeScreenshot(situation);
        Thread.sleep(3000);
        DriverUtils.getDriver().stop();
    }
}

Be aware that my ‘public void setUp()’ technique in Hooks exhibits the tag @UI within the @Earlier than as ‘@Earlier than(“@UI”)’ above it. I in some way had eliminated the ‘@UI’ tag from above the ‘Situation’ line in my Characteristic File. So, I wasn’t calling the ‘setUp’ technique within the very first place. Including that mounted the whole lot, so the start of my Characteristic File seems to be like this:

Characteristic: ARCCP-T001 - Sanity Check of PROD COMPANY Shopper Portal Important Performance

@ProdSmoke @TC1.38 @ARCCP-T138 @TestCaseKey=ARCCP-T138 @UI
Situation: Person logs in, clicks important buttons, logs out, logs in, logs out
