LWP July: Measurement and observability

LWP July: Measurement and observability

The covid era has made us all obsessed with numbers. Are they right? Are they valid? Do they tell the story you need to hear or the one you want to imagine? In web perf, of course, numbers are our native language, and we’ve been arguing about methodologies since the dawn of time (which is about 2006, in web perf terms).

This month we’re bringing you the unparalleled brilliance of Emily Nakashima, who manages the engineering and design teams at Honeycomb.io, and delivered one of the best received talks at Perf.now in Amsterdam last year. She’ll be asking us to consider the connection between performance and user happiness through the lens of observability.

Web performance enthusiast and Googler Rick Viscomi will introduce us to the measurement tools that allow tracking of the new Core Web Vitals metrics Google is advocating as the best way to understand how users experience the web.

LWP June: Coronavirus surge

LWP June: Coronavirus surge

In the chaos of entering lockdown, many businesses, especially in travel and hospitality, had good cause to wonder if Covid-19 might be the end of them. Restaurants, shops, cinemas and gyms all closed their doors. But just as these businesses faced a struggle for survival, others started experiencing the opposite problem.

As a food delivery business, how do you cope when seemingly every person in the country who has ever had a Gousto account suddenly wants to order a delivery at the same time? What about video streaming? And how are these things affecting our internet experience as a whole? How is the network coping with everyone suddenly being on Zoom?

Join us to hear about how as the world has a health crisis, the internet is in pretty good shape.

LWP May: Regulation and compliance

LWP May: Regulation and compliance

For our second month of online-only LWP, we will be turning our attention to compliance. Cookie consent, tracking permissions, PII, data sharing, cross domain leakage… there’s a lot for us to worry about these days, and we’ve got to make it all performant too!

Emanuil Tolev from Elastic joins LWP veteran and accessibility expert LĂ©onie Watson for an event devoted to finding the perfect balance between engagement, experience, and compliance.

By attending this event you agree to learn things and have fun. Knowledge provided, food up to you. Bring your own wifi.

LWP April: Migrations

LWP April: Migrations

We’re back, and we’re 100% online. Our event that we had scheduled for March will now go ahead on our April schedule, but we will be live streaming ONLY, so you cannot attend in person. To attend, there is no need to register, just follow the link shown below. If you have Zoom, it will launch and join the call automatically, otherwise it will prompt you to install.

Things have changed a lot since the early days of the web, and one of those ways is in the importance of resilience. Resilience drives architectural decisions which prioritise fault tolerance, and also changes the way we think about migrations. No technology decision lasts forever, and when the time comes to move on, how do you do it without impacting availability, or end user experience?

The days are gone when it was good enough to throw up a maintenance page and load your one set of servers in a van (all at once). Today migrations are complex, challenging, and intricate operations. When done well though, a migration can unshackle you from legacy decisions, accelerate growth or open up new possibilities for better performance.

This month we will host two inspiring stories of migrations of different kinds. Robin and Stacey from Compare the Market share their experience of moving infrastructure from on-premise to the cloud, while GDS’s Matt Hobbs will cover their long journey to enable HTTP/2 on gov.uk.

Make sure you’re on the zoom by 19:00 London time for the first talk!

LWP February: What’s new in HTTP

RVU

This February, we welcome two protocol experts to London Web Performance, to help us get up to date on our use of HTTP. Having got our heads around HTTP/2, and with it said goodbye to old practices like domain sharding and bundling, HTTP/3 is arriving to iron out the kinks in HTTP/2. It may be more of an under-the-hood update, but it’s worth understanding how this will impact your page load performance.

Meanwhile, HTTP headers have been a wild west of poor standardisation for years. Structured headers is arriving and will finally bring some order to the chaos, allowing a single parser to handle all compliant headers. Find out what structured headers will mean and take advantage by writing your custom headers using structured headers syntax.

LWP January: new year, new framework?

General Assembly

Many of us have now been using our preferred front end framework for years. Whether it’s Ember, Angular, React, Vue, or Svelte, there’s no shortage of different schools of thought on how we should organise our applications in the browser.

New years often give us a chance to think afresh about our habits and try something new, so we thought it was about time we did a frameworks event. This is not some kind of showdown – we are looking objectively at the pros and cons of different methods and encouraging a holistic view taking in developer experience and learnability as well as performance and good defaults.

Talks for this meetup will be announced just before our December event
