This week we’re talking with Pia Mancini about the latest updates to the mission of Open Collective. Earlier this year Open Collective announced “Funds for Open Source.” The idea is simple, make it easy for companies to invest in open source, and they will. Also, since recording this episode, Pia and the team at Open Collective along with Gitcoin announced fundoss.org as part of Maintainer Week announcements. And right now, they have a matching fund of $75,000 dollars funding open source that you can support.
Yulia Startsev from Mozilla’s SpiderMonkey team joins Jerod & Feross to talk compilers, going back to get your Master’s, making decisions as a group, process of shepherding a feature through TC39, how Firefox actually works, and LavaMoats. Yes, LavaMoats.
This animated “children’s” book is spectacularly good. It centers around a growing community of otters, their struggles to communicate efficiently, and one little otter named Nixie’s great idea that changed the forest forever.
Put, put, put your events
gently in the stream
There they’ll float, down and down
In the river’s gleam
CockroachDB comes with new easy-to-use SQL syntax for configuring a database across multiple regions. One of these SQL features is to declare a table to have the locality
REGIONAL BY ROW, allowing developers to place individual rows of a table in a specific region whilst maintaining the facade of a single SQL table, for example:
CREATE TABLE users ( id UUID PRIMARY KEY DEFAULT gen_random_uuid(), username STRING NOT NULL UNIQUE ) LOCALITY REGIONAL BY ROW;
With this extra piece of syntax during CREATE TABLE, they’ve made row-level data homing simple.
DenoDB has a fully-typed API (which is great for editor integration) and supports a whole host of backends: MySQL/Maria, SQLite, Postgres, and MongoDB.
Broad database support is great for library adoption, but as a user I’d prefer something that leans in to a specific ecosystem, which usually lets you squeeze more out of it.
Regardless of that, it’s great to see the Deno community building foundational tools like this.
Git is actually sooo hard. Not just to learn, but also to use consistently. And I say that as a person who used it for probably over ten years. Here’s my thoughts on the matter.
What you will see next is a highly subjective, non-exhaustive unordered list of principles that, if you follow, I can guarantee will lead you to become a bad developer…
If your goal, fellow reader, is to become a good developer instead, don’t worry. Remember that via negativa is way more powerful than via positiva. That means that knowing what not to do is safer and easier to figure out than exactly what to do. So pay attention to the following topics and decide which type of developer you want to be.
I (dis)agree with every thing that Rafael lays out. I’ll add a bad one of my own: Optimize immediately! Because if your code doesn’t run at ludicrous speed, does it even matter if it executes correctly?!
A bad CLI can easily discourage users from interacting with it. Building successful CLIs requires attention to detail and empathy for the user in order to create a good user experience. It is very easy to get wrong.
In this guide I have compiled a list of best practices across areas of focus which aim to optimize for an ideal user experience when interacting with a CLI application.
Porter lets you package your application artifacts, client tools, configuration and deployment logic together as a versioned bundle that you can distribute, and then install with a single command. Written entirely in Go, we speak to one of the creators about running an open source project, the importance of documentation, and more.
One of Teleport’s Features is Access Workflows. Teleport allows users to request elevated privileges in the middle of their command-line sessions. Privilege elevation requests can be approved or denied via ChatOps in Slack or anywhere else via flexible Authorization Workflow API.
This video shows how to configure Slack with the Approval Workflow - requesting access roles; setup integration between Teleport and Slack to provide role based access requests.
Yejun Su is using Numerical Elixir’s new Livebook project for more than just Numerical Things.
Before Livebook, I write code in IEx, which is a REPL. It has some helpers to ease the way to explore code, but in my opinion, Livebook exceeds in two factors:
In fact, IEx can enable code history by setting
export ERL_AFLAGS="-kernel shell_history enabled"in the shell profile file. You can also search the IEx code history with Ctrl-r and apply it. But as Livebook is essentially a notebook, you can see all texts and evaluation results without the need to set anything.
Livebook has a clean UI. You can write documents in Markdown and evaluate Elixir code blocks. It is more continuous, you can review every step of your thought by scrolling the page.
Utopia is an integrated design and development environment for React. It uses React code as the source of truth, and lets you make real time changes to components by editing it and using a suite of design tools. It’s early software, but you can try it today, look at an example project, or read about it on our blog!
We talk with Ryan about the massive success of Node and how it impacted his life, and how he eventually created Deno and what he’s doing differently this time around. We also talk about The Deno Company and what’s in store for Deno Deploy.
This week on Ship It! Gerhard talks with Ian Miell, author of Docker in Practice as well as Learn Git, Bash, and Terraform the Hard Way. They talk about being comfortable with the uncomfortable, focusing on the tech while keeping a holistic view of the business. Following the money is key. Ian explains this concept really well, and Gerhard feels fairly confident you will be better off if you pay attention. Let us know in the comments!
Althttpd is a simple webserver that has run the sqlite.org website since 2004. Althttpd strives for simplicity, security, and low resource usage.
As of 2018, the althttpd instance for sqlite.org answers about 500,000 HTTP requests per day (about 5 or 6 per second) delivering about 50GB of content per day (about 4.6 megabits/second) on a $40/month Linode. The load average on this machine normally stays around 0.1 or 0.2. About 19% of the HTTP requests are CGI to various Fossil source-code repositories.
Richard has a knack for creating simple, high quality tools. When we did our (now legendary) show with him back in 2016, he was quite keen on coming back at some point to discuss Fossil. Should we make that happen?
I’ve been tasked with leading frontend. As a result, I’ve been teaching a whole lot of people about the web.
Knowing where we came from can help us figure out where we should go. It’s also a mountain of technical debt, and we’re collectively building on top of it.
Forgive me if I skip the wonderful stories of Macromedia Flash, Java in the browser, or whatever other detour you can think of. While those were important to development of the web, most of us will never run into them again.
The first Hyper Text Markup Language (HTML) spec was released in 1993 as a way to represent web pages, then documents….
A sweeping history (replete with screen shots) that ends with a peek into the potential future.
You’ve probably seen many of these commands hit Changelog News over the years, but now you can see them all again in one hand-curated place. Who knows, maybe one or two will be new to you. I hadn’t heard of curlie previously, which looks like a nice merging of
A quick list of 23 skills for varying levels of seniority, from senior, to staff, and beyond. My favorites from the list are How to listen to other engineers’ ideas without feeling threatened (#10) and How to pick your battles (#18) .
Everyone else’s favorite, according to the top highlight, is How to get someone promoted (#19).
William Falcon wants AI practitioners to spend more time on model development, and less time on engineering. PyTorch Lightning is a lightweight PyTorch wrapper for high-performance AI research that lets you train on multiple-GPUs, TPUs, CPUs and even in 16-bit precision without changing your code! In this episode, we dig deep into Lightning, how it works, and what it is enabling. William also discusses the Grid AI platform (built on top of PyTorch Lightning). This platform lets you seamlessly train 100s of Machine Learning models on the cloud from your laptop.
When it comes to scaling, we might need to think about:
- data storage, if we store more and more data and it becomes expensive or slow working with them
- fast INSERTs and UPDATES for write-heavy workloads
- making SELECT queries faster because of their complexity or because they need to query huge amounts of data
- concurrency if we have many clients interacting with the database
In this article, I will present some basic ideas and starting points on scaling traditional SQL databases.
