Migrating Messenger storage to optimize performance

More than a billion people now use Facebook Messenger to instantly share text, photos, video, and more. As we have evolved the product and added new functionality, the underlying technologies that power Messenger have changed substantially. When Messenger was originally designed, it was primarily intended to be a direct messaging product similar to email, with messages waiting in your inbox the next time you visited the site. Today, Messenger is a mobile-first, real-time communications system used by businesses as well as individuals. To enable that shift, we have made many changes through the years to update the backend system. The original monolithic service was separated into a read-through caching service for queries; Iris to queue writes to subscribers (such as the storage service and devices); and a storage service to retain message history. This design optimized Messenger for a mobile-first world and helped fuel its success. To help improve Messenger

Firefox 61 Arrives With Better Search, Tab Warming, and Accessibility Tools Inspector

On Tuesday, Mozilla released Firefox 61, the newest version of its web browser for Windows, Mac, Linux, and Android platforms. The release builds on Firefox Quantum, which the company calls “by far the biggest update since Firefox 1.0 in 2004.” VentureBeat: Version 61 brings TLS 1.3, the ability to add custom search engines to the location bar, tab warming, retained display lists, WebExtension tab management, and the Accessibility Tools Inspector. Mozilla doesn’t break out the exact numbers for Firefox, though the company does say “half a billion people around the world” use the browser. In other words, it’s a major platform that web developers have to consider.

New – Amazon Linux WorkSpaces

Over two years ago I explained why I Love my Amazon WorkSpace. Today, with well over three years of experience under my belt, I have no reason to return to a local, non-managed desktop. I never have to worry about losing or breaking my laptop, keeping multiple working environments in sync, or planning for disruptive hardware upgrades. Regardless of where I am or what device I am using, I am highly confident that I can log in to my WorkSpace, find the apps and files that I need, and get my work done.
Now with Amazon Linux 2 As a WorkSpaces user, you can already choose between multiple hardware configurations and software bundles. You can choose hardware with the desired amount of compute power (expressed in vCPUs — virtual CPUs) and memory, configure as much storage as you need, and choose between Windows 7 and Windows 10 desktop experiences. If

Firefox gets speedier tab switching, a new accessibility tool for developers and more

Mozilla today released version 61 of its Firefox browser. By now, it’s no secret that Firefox is back in contention as a serious competitor to Google’s Chrome browser and while the new release doesn’t offer any groundbreaking new features, all of the new improvements and tools in Firefox 61 are good examples for why Firefox is worth another try.
Two of the new features focus on speed, something Firefox was sorely lacking for a while but now offers plenty of.
The first of these is tab warming, which essentially makes switching between tabs faster because Firefox already preemptively starts loading a tab (after a small delay) when you are hovering over it. Once you do click on that tab, much of the rendering has already been done, so switching between tabs now feels faster.
The other new performance-related feature is ‘retained display lists.’ Whenever Firefox renders a page, it builds a display list

Running graphics-accelerated GUI apps in LXD containers on a Ubuntu desktop

Note: This post is about LXD containers. These are system containers, which means they are similar to Docker but behave somewhat like virtual machines. When you start a LXD (lex-dee) container, you are starting a new system on your computer, with its own IP address and all. You can get LXD as a snap package. Go https://docs.snapcraft.io/core/install to install snap support, then sudo snap install lxd. See also Getting Started with LXD.
In that older post, we saw how to setup a LXD container in order to run GUI apps from there, and have them appear on our X11 desktop.
How to run graphics-accelerated GUI apps in LXD containers on your Ubuntu desktop

In this post, we are going to see how to easily set up our LXD installation in order to be able to launch on demand containers that we can run GUI apps in them. First, we will see the instructions

Consul 1.2 release

We are excited to announce the release of HashiCorp Consul 1.2. This release supports a major new feature called Connect that automatically turns any existing Consul cluster into a service mesh solution. Connect enables secure service-to-service communication with automatic TLS encryption and identity-based authorization.

Download Now

Consul is currently deployed on millions of machines worldwide. After upgrading to Consul 1.2 and enabling Connect, any existing cluster will instantly become a service mesh solution that works on any platform: physical machines, cloud, containers, schedulers, and more.

Modern Service Networking with Service Mesh

A service mesh is necessary for organizations adopting microservices and dynamic cloud based infrastructure. Traditional host-based network security must be replaced with modern service-based security to accommodate the highly dynamic nature of modern runtime environments.
A service mesh provides a highly available, distributed solution to three critical problems:

Discovery: Services must be able to find each other.

Configuration: Services
