Almost one in five UK mortgage holders have now been granted a payment holiday, it was estimated this week – but people’s experiences of the process have been very different. Some struggled to get a holiday while others say it was almost too easy. And while for some it will add just a few pounds to their monthly mortgage bill, others say their outlay will rise by a lot more.

The Guardian asked readers who had applied for a mortgage payment holiday, or help with other debts, how they got on. Almost 200 people contacted us to tell us their stories.

An essential part of the recruitment process for any new teacher is meeting the pupils: but how do you do that under lockdown regulations?

If you are a teacher looking to move between schools during the coronavirus lockdown, how can you make the most of the online education experience with your new class? This is interesting new territory for many teachers. But there are thousands and thousands of teachers and pupils already learning remotely, in virtual schools – can they offer insights?

At a virtual school, lessons are delivered in line with each person’s personalised curriculum. Exactly as you would expect in a physical school space, pupils are taught how to interact with teachers, their peers and lesson content using whiteboard technology, quizzes, voice and video as well as receiving and sending assignment tasks. How should you introduce yourself to a new class, if you are meeting them online for the first time? If we consider how teachers deliver excellent classroom teaching practice in a physical space, how they prepare should not be approached any differently in an online environment.

For a while supper and wine were sufficient; now I’m watching every adaptation that is better than its source material

I suspect I’m not alone in this but, at some point in the past two weeks, I hit my lockdown wall. Not literally, although apparently the “banging one’s head against the kitchen wall” phase kicks in on the eighth week, so that’s something to put in the diary. But last week I felt really, really over it. Enough with every day being the bloody same; enough with watching my children become increasingly fretful because they haven’t seen their friends in over a month, the equivalent of five years to a pair of four-year-olds. But unless you want to be one of those delightful people protesting the lockdown in the US, clothed in stars and stripes, AK-47s across their backs, what choice do we have? So, like Bill Murray, we grind out the same day, again and again and again.

The trick is to invent things to look forward to. For a while, “supper” and “wine” were sufficient, but repetition has dulled their efficacy. So I set myself challenges, driven on by the thrill of completion. Some people hear the word “challenge” and think, “Fitness!” Those people are not me. “Rewatch the entirety of 30 Rock” is more my speed. It is so soothing to watch a show about a luxuriantly bouffanted New York tycoon who isn’t a moron. In a just world, Jack Donaghy would be the US president instead of, well, you get the point. Then, sparked by his brilliant turn as Chris Tarrant on the ITV drama, Quiz, my next challenge was, “Watch every Michael Sheen performance in which he plays a real person”. This was deeply enjoyable, even if, in my lockdown-confused mind, I now think Brian Clough interviewed Richard Nixon on TV and Kenneth Williams was prime minister when Diana died.

The broadcaster, 58, on God, privacy, Mini convertibles, the rudeness of Madonna and her school nickname, Vanessa the Undresser

Even aged two, I was a child of great perspicacity. At nursery we had to answer the register by saying “Yes, Auntie” or “Present, please”, which I found deeply confusing. First, I thought, you’re not my auntie. And if I’m asking politely for a present every day, where on earth is it?

Vanessa the Undresser was my nickname at school, and I put that down to my parents. When a sex scene started on TV I was banished to the hall. I’d stand with one ear against the door desperately trying to work out who was doing what to whom and in what position. Thus was aroused in me an unshakable thirst for sex in all its permutations. I’ve never tired of it, menopause or not.

Your questions answered on what type of mask to wear to cut the risk of getting Covid-19

• Coronavirus – latest updates
• See all our coronavirus coverage

Yes. Different types of mask offer different levels of protection. Surgical grade N95 respirators offer the highest level of protection, preventing the user from becoming infected with Covid-19, followed by surgical grade masks. However, these masks are costly, in limited supply, contribute to landfill waste and are uncomfortable to wear for long periods. So even countries that have required the public to wear face masks have generally suggested such masks should be reserved for health workers or those at particularly high risk.

Well...it seems like these cats are more interested in all those mouses and cookies hiding in your computer.  

During this crazy time many of us have been confined to our homes and for some that means to be home 24/7 with our best friends. Our pets. However, because of this, many pets have become accustomed to having us home with them. 

But then the question is... will they be okay once bans are lifted and people are able to slowly go back to their daily routines?

Will they be able to handle their best friends not being by their side 24/7?

It is expected that many dogs (even cats!) can suffer from separation anxiety, and pet experts are saying that it's a good idea to get your pet ready and used to post-quarantine separation now, to minimize their stress later. 

Here are some useful tips for both dog and cat owners.

Without any modifications, React is really fast as-is. There are, however, a few things that you can do to improve performance. While working at HelloSign, I discovered some quick fixes that made our apps incredibly snappy. With these simple changes, I was able to reduce render time from over 3000 milliseconds to less than 200 milliseconds.

Editor’s Note:

Check out our upcoming React University Workshops. Our next workshop, React 2016, will be held on April 23 at Microsoft Reactor in San Francisco and will offer a deep dive into creating modern Single-Page Applications (SPA) using React, Redux, React Router, Immutable.js, and Webpack. Also, if you’re interested in learning the basics about what it takes to be a Data Visualization Engineer, check out React and D3.

Introduction

HelloSign is a cloud-based electronic signature tool founded in 2010. As you can imagine, HelloSign is a very JavaScript-heavy codebase. A lot of client-side behavior is necessary to create a rich signing experience. Lately, we’ve moved much of our codebase toward React. In fact, in many places we’ve broken up our codebase into several single-page applications written in React.

Although the HelloSign team was happy with React’s performance before I initially joined the project, I quickly found some low-hanging fruit that could improve runtime speed. Here are the steps you should take to see similar improvements in your own applications.

Create a Baseline Performance Measurement

Before you begin, you should take a baseline measurement. Optimizations are meaningless if you can’t verify the results of your modifications.

Thankfully, Chrome has excellent developer tools to help. One, little-used feature of Chrome’s DevTools is the “Timeline” tool. It allows you to record and analyze all activity in your application. You can record interactions on the page, locate potential memory leaks, measure the total time it takes to perform a task, and identify areas of potential jank. Best of all, the results can be recorded for comparison with your final benchmark.

There’s actually a really awesome video on Chrome’s DevTools that goes into detail about the “Timeline” feature. You can view it here.

We chose to measure the time elapsed between the initial paint of our signer page to the final rendering of the entire page. The initial download of our bundles still needs some optimization, but we’re neither going to mess with nor measure this parameter. It’s fairly easy and consistent to test render time rather than trying to click areas around the page and trying to measure its performance in a repeatable way. Then, all we needed to do was to go to the signer page, open Chrome’s DevTools “Timeline” tab, and refresh the page.

As a side note, make sure that when performing this test, the “Paint” and “Screenshots” boxes are checked so that you can see what the user sees as the page is being rendered.

After all that, we determined that our rendering time from initial paint was a little over 3 seconds. Much too long. Luckily, there was little we had to do to make this quite a bit faster.

Set NODE_ENV to Production

This step is easy to get wrong, even if you are well-informed. React’s documentation provides an overview, but doesn’t provide many specifics. React has great developer warnings and error checking, but these are only intended for development; if you take a look at React’s source code, you’ll see a lot of if (process.env.NODE_ENV != 'production') checks. This is running extra code that is not needed by the end user, not to mention that calling process.env.NODE_ENV is extremely slow. For production environments, we can remove all this unnecessary code. Just keep in mind that you don’t want to do this in development because it will remove all those helpful developer warnings.

If you’re using Webpack, you can use DefinePlugin to replace all instances of process.env.NODE_ENV with 'production', and then use the UglifyJsPlugin to remove all the dead code that no longer runs. Here’s a sample setup that you might use:

// webpack.config.js
  ...
  plugins: [
    new webpack.DefinePlugin({
      // A common mistake is not stringifying the "production" string.
      'process.env.NODE_ENV': JSON.stringify('production')
    }),
    new webpack.optimize.UglifyJsPlugin({
      compress: {
        warnings: false
      }
    })
  ]
  ...

React Constant and Inline Elements Transforms

React 0.14 introduced support for certain transpile time optimizations with Constant and Inline Element Babel Transforms. React Constant Elements treats JSX elements as values and hoists them to a higher scope. In other words, it hoists static elements and thereby reduces calls to React.createClass. React Inline Elements converts JSX elements into the object literals that they eventually return. Again, this minimizes the runtime calls to React.createClass.

The implementation is rather simple. We added our Babel configuration in our package.json file:

// package.json
  ...
  "babel": {
    "env": {
      "production": {
        "plugins": [
          "transform-react-constant-elements",
          "transform-react-inline-elements"
        ]
      }
    }
  },
  ...

Final Measurement / Conclusion

Lastly, you’ll want to run the benchmark again and compare it with that saved benchmark from before these optimizations. As you can see, the total runtime profile ends 200ms after initial paint! That’s 15 times faster!
