VSCode themes in CodeSandbox?

Ives van Hoorne writes on Medium: Personalizing color schemes is one of the most important things to have in an code editor. CodeSandbox didn’t have any way to personalize colors in the editor since release, but I’m happy to announce that we do now. The best part is that we were able to reuse a big chunk of logic from VSCode directly and also support any VSCode theme natively in CodeSandbox!

CodeSandbox launched their dashboard and teams feature

I've been closely watching CodeSandbox and have been thoroughly impressed with the work Ives van Hoorne and the 75+ contributors have put into this online code editor for ... React, Preact, Vue, and more. I've been thinking about getting Ives on Founders Talk to talk about the business model behind CodeSandbox. It seems to have this interesting self baked, pay what you want, Patron model to cover the expenses of CodeSandbox. Most of the features are free with limits, and being a "Patron" lifts those limits + extra features, and supports the costs and development efforts.

React Native at Airbnb

This epic four part series from the Airbnb engineering blog showcases how React Native was used at Airbnb to enable their teams to move quickly and maintain a great developer experience. However, in the end, they decided to sunset React Native and focus on native — but their journey to that conclusion is well worth a read. Part 4: Sunsetting React Native — Although many teams relied on React Native and had planned on using it for the foreseeable future, we were ultimately unable to meet our original goals. In addition, there were a number of technical and organizational challenges that we were unable to overcome that would have made continuing to invest in React Native a challenge. As a result, moving forward, we are sunsetting React Native at Airbnb and reinvesting all of our efforts back into native. It's not all bad though. 63% of their engineers would have chosen React Native again given the chance and 74% would consider React Native for a new project. Gabriel went on to say: React Native is progressing faster than ever. There have been over 2,500 commits in the last year and Facebook just announced that they are addressing some of the technical challenges we faced head-on. Even if we will no longer be investing in React Native, we’re excited to continue following its developments. For a different perspective read Should we use React Native? — a follow-up post to this four part series.

Is the internet at the mercy of a handful of developers?

In this post from Casper Beyer titled The Node.js Ecosystem Is Chaotic and Insecure, he cites examples like left-pad, is-odd, is-number — and goes on to say the way to be responsible with dependencies is... ...don’t trust package managers, every dependency is written by some random developer somewhere in the world and is a potential attack vector. ... Is this being too paranoid? Perhaps, or maybe it’s the healthy amount considering the massive reach these trivial packages can have. While this focuses on Node.js, the lessons learned apply anywhere you have dependencies in your code.

We do Scrum but…our management doesn’t.

Bummer. I've been there. It's so tough to make iterative change to software when those who are "in charge" of what you do everyday keeps interrupting or changing the rules to the game. Sjoerd Nijland writes on the Serious Scrum blog: As Scrum is a framework for developing, delivering, and sustaining complex products, and, if your management isn’t actively engaged in this exercise, it indeed may not make immediate sense for them to adopt the framework. Scrum could thus be perceived to be for developers only. Or perhaps Scrum was introduced by and is still contained to the development organization. In this case it may make sense to talk about the definition of ‘Product’. Would it make sense for the Management Team, to consider the organization itself as a product? If your team does Scrum, you should 100% read this.

What are you optimizing for?

Saron Yitbarek, creator of CodeNewbie, says this is the one question that will change your life — it did for her. I encourage you to read this from end to end, and then truly ponder this question for your life. I don’t remember why he said it, but I remember the car we were in on our way to a fancy networking event full of important people doing boss shit when he looked at me and asked, "What are you optimizing for?" ... I don’t think he knew it was that deep. It was. If reading this makes a significant impact on your life, I want to hear about it. Tweet at us.

An Efail postmortem

Efail caused a panic at the disco: ... some researchers in Europe published a paper with the bombshell title “Efail: Breaking S/MIME and OpenPGP Email Encryption using Exfiltration Channels.” There were a lot of researchers on that team but in the hours after release Sebastian Schinzel took the point on Twitter for the group. Oh, my, did the email crypto world blow up. The following are some thoughts that have benefited from a few days for things to settle. Lots of interesting insights here, perhaps most controversially how the EFF's handling of the situation may have done more harm than good in the author's opinion. Also: we could stand to have a renewed appreciation for OpenPGP’s importance to not just email crypto, but the global economy. I can say I definitely have more appreciation for it after reading this than I did before. I hadn't thought about its influence (which is huge) outside of encrypted email.

Want to debug latency?

What is latency? And how exactly do you debug it? Jaana writes on the Observability+ blog: In the recent decade, our systems got complex. Our average production environments consist of many different services (many microservices, storage systems and more) with different deployment and production-maintenance cycles. Measuring latency and being able to react to latency issues are getting equally complex as our systems got more complex. This article will help you how to navigate yourself at a latency problem and what you need to put in place to effectively do so.

What if JavaScript wins?

Very insightful post from Anil Dash about the impact of network effects on JavaScript and coding culture. Anil writes on his Medium: What this suggests is that JavaScript may be reaching escape velocity as a network, and as an ecosystem of related technologies. To be clear, there’s no winner-takes-all here — domain-specific languages will always have their uniquely valuable areas of focus. But for general-purpose coding? Everything from spreadsheet macros to Internet of Things hardware seems to default to having JavaScript be one of the primary ways to make things programmable.

You’re not lazy

The subtitle here should have been “We’re all very !#$@%#$ afraid”. The reason I often hold back from doing something or when I self-sabotage a goal — the real reason is because I’m afraid of what will happen if this thing is actually successful??! Then, I’ll have to actually do it. 😱 John Gorman, writes for Personal Growth on Medium: Fear doesn’t manifest itself like you think, because often times we don’t give it the chance to. Fear isn’t always the sweaty palms that stop us cold in a job interview — fear is generally what prevents us from applying in the first place. Spend 8 minutes and read this.

Building bridges to GopherCon 2018

Ashley McNamara is doing a series of fundraisers starting now and ending on July 1st. The goal is to raise money for GoBridge and WomenWhoGo — two organizations who make it their mission to educate & empower underrepresented communities. I can't wait to see how many of these tees the community will be wearing at GopherCon later this year. I'm imagining a sea of Gophers rocking these shirts!

Why decentralization matters

Chris Dixon on Medium: Early internet protocols were technical specifications created by working groups or non-profit organizations that relied on the alignment of interests in the internet community to gain adoption. This method worked well during the very early stages of the internet but since the early 1990s very few new protocols have gained widespread adoption. Cryptonetworks fix these problems by providing economics incentives to developers, maintainers, and other network participants in the form of tokens. They are also much more technically robust. For example, they are able to keep state and do arbitrary transformations on that state, something past protocols could never do. What Chris is advocating is the protocols of the past weren't made for the internet of the future. The next era of the internet is being built with Web 3.

What I wish I knew when I became CTO

From David Mack, CTO and co-founder of SketchDeck: You can accumulate responsibility faster than you can learn how to harness it. I now appreciate that the infrastructure, frameworks, and languages you choose will stick with you for a really long time. Only hire when you feel you’re completely desperate for the role. Hire to keep up with growth, not to generate it. I really appreciated David's thoughts on hiring.

Announcing AI Fund

Andrew Ng shared his plans for his newly created AI Fund — with investments including NEA, Sequoia, Greylock Partners, SoftBank Group, and others. Andrew Ng: I am excited to announce the formation of the AI Fund. We have raised $175 million, and will be sequentially initiating new businesses that use AI to improve human life. In the early days of electricity, much of the innovation centered around slightly different improvements in lighting. While this was an important foundation, the really transformative applications, in which electric power spurred massive redesigns in multiple industries, took longer to be grasped. AI is the new electricity, and is at a similar inflection point. Given Andrew Ng's prominence and success in bringing AI to industry, and his partnership with some of the world's premier technology investment firms, this announcement may well signal the next wave of capitalization for AI-oriented startups.

Meltdown and Spectre Explained

If some or most of what you've heard or read about Meltdown and Spectre has gone over your head, then you should 💯 read this technical explainer from Matt Klein (also known for being the creator of Envoy). Matt: I have not seen a good mid-level introduction to the vulnerabilities and mitigations. In this post I’m going to attempt to correct that by providing a gentle introduction to the hardware and software background required to understand the vulnerabilities, a discussion of the vulnerabilities themselves, as well as a discussion of the current mitigations. Matt goes on to share graphic charts of CPUs, virtual memory, and code samples to breakdown the exploit.
