From Lerna/Yarn to Nx: Faster Build Times and Better Dev Ergonomics

In this video I’ll compare monorepo tools such as Lerna/Yarn workspaces/PNPM workspaces with Nx. The video walks you through the steps of adding Nx to a Lerna repo and showing many affordances Nx offers. Although the video uses Lerna, everything said applies to Yarn or PNPM. Basically, any time I say “Lerna” you can substitute it for Yarn or PNPM.

Clarifying Misconceptions

Misconception: You have to choose between Nx and Lerna.

Lerna, Yarn workspaces, pnpm workspaces offer the following affordances for developing multiple projects in the same repo:

• Deduping node_modules. If I use the same version of say Next.js in all the projects, the package is installed once.
• Task orchestration. If I want to test all the projects, I can use a single command to do it.
• Publishing (Lerna only). I can run one command to publish packages to NPM.

This is what Nx offers:

• Smart rebuilds of affected projects
• Distributed task execution & computation caching
• Code sharing and ownership management
• High-quality editor plugins & GitHub apps
• Powerful code generators
• Workspace visualizations
• Rich plugin ecosystem
• Consistent dev experience for any framework
• Automatic upgrade to latest versions of all frameworks and tools

Migrating from Lerna to Nx: Better Dev Ergonomics + Much Faster Build Times

In this post and video I’ll compare two dev tools for working with monorepos: Lerna and Nx.

Lerna offers several great affordances for developing multiple projects in the same repo, and it’s used by many open source projects. Nx is developed by former Googlers and provides a richer monorepo-based developer experience. Nx has a lot more in common with the tools you find at companies like Google, Uber, and Twitter.

In addition to comparing Lerna and Nx, I’ll show how to migrate your repository from Lerna to Nx.

Playground Games and Turn 10 Studios respectively improved time on Visual Studio 2019

The C++ team at Visual Studio has delivered substantial build and link time improvements throughout Visual Studio 2019. This blog is Part 2 of a series of blogs showcasing real-world results of our efforts. See how the Gears 5 team benefited from iteration build time improvements in Part 1.

How to Install and Configure Chrony

It is essential to keep the correct time on a server. This is especially true when it comes to processing financial transactions or other vital functions which need to be handled in a specific order. Using the Network Time Protocol (or NTP), computers can synchronize their internal clock times with the internet standard reference clocks. In essence, NTP is a hierarchy of servers. The higher the Stratum number of a server, the more accurate the timing is and the lower the Stratum number of a server is, the lower the accuracy and time stability. Stratus are defined by the distance from the initial reference clock.

Python Datetime Tutorial: Manipulate Times, Dates, and Time Spans

Dealing with dates and times in Python can be a hassle. Thankfully, there’s a built-in way of making it easier: the Python datetime module.

datetime helps us identify and process time-related elements like dates, hours, minutes, seconds, days of the week, months, years, etc. It offers various services like managing time zones and daylight savings time. It can work with timestamp data. It can extract the day of the week, day of the month, and other date and time formats from strings.
