<p>In the last week I have been informed by two major websites, Amazon and Coinbase, that the computer I have been using for the last two years is a "new device" and must be confirmed.</p>
<p>In both instances reconfirming the device via email solved the problem and I kind of forgot about it.</p>
<p>Then just now, whilst using Coinbase I was logged out because of an auth token error. I then had to log back in. 2 stage auth token is working fine.</p>
<p>Is someone trying to hack me or perhaps one of the two above mentioned sites? (I am sure someone somewhere is trying to hack them both ALL THE TIME... is someone getting close????)</p>

d_InterceptionsPerAttempt = (2.375f - ((float)(Interceptions/Attempts) * 25f)); //formula for interceptions per attempt
PasserRating = (((a_CompletionPercentage + b_YardsPerAttempt + c_TouchdownsPerAttempt + d_InterceptionsPerAttempt)/6)*100f); //formula for passing rate

I am trying to write a MACRO in EXCEL.
I have multiple sheets and I want to filter based on the YELLOW fill color.
How do I write macro for this ? My apologies if my question sounds dumb but I really want to learn MACROS in Excel.

<p>Could you add a working code on the sandbox?</p>
<p>though there are other discussion:
<a href="https://stackoverflow.com/questions/54062100/shownotification-in-react-admin-doesnt-work">showNotification in react-admin doesn't work</a>
<a href="https://github.com/marmelab/react-admin/issues/3402" rel="nofollow noreferrer">https://github.com/marmelab/react-admin/issues/3402</a>
they all did not work.</p>
<p>I need a working code on the sandbox so I know what I miss.</p>
<p>Thanks.</p>

58,117,890 | How to test components using new react router hooks? | <p>Until now, in unit tests, react router match params were retrieved as props of component.
So testing a component considering some specific match, with specific url parameters, was easy : we just had to precise router match's props as we want when rendering the component in test (I'm using enzyme library for this purpose).</p>
<p>I really enjoy new hooks for retrieving routing stuff, but I didn't find examples about how to simulate a react router match in unit testing, with new react router hooks ?</p>
