When media or politicians discussed regulating the software industry, I feared that the regulation would close the door to newcomers. Opening the doors to more startups and people should make “disruptions” less painful and more beneficial to our society. This belief made me against most regulatory approaches.
But I heard an analogy of the architecture design of a building vs. the actual building that changed my mind. An architect student is free to come up with a plan and learn from it, but the construction of the design that could affect people’s lives should be regulated. We can apply the same thinking to code vs. running service. This analogy will be my frame of thinking going forward.
Do you let people outside your team commit to your codebase? I have heard and seen that different approaches at different companies: from collective code ownership of Facebook to strong code ownership at my previous employers. Most likely, the procedures are more organic than chosen consciously. Food for thought.
If anything, I like the sound of “quantum supremacy.” It is something out of a sci-fi. Seriously, though, quantum supremacy is an idea that there is a set of problems cheap for quantum computers, but prohibitively expensive for classical computers. Cracking modern cryptography could be one such problem. The linked blog post about Google’s achievement is human-readable, so check it out!
Since there are so many chat apps, your product manager wants to add the feature to your app as well. You may think it’s just another WebSocket feature and say yes. And you will spend days and nights solving group chat moderation and abuse monitoring. I know. I have been there. Think through the feature and understand possible implications beforehand.
As I gain more years of experience, I keep wondering about a couple of things. First, where do I go from here? Second, where will I be when I retire? Per the first question, these two articles (here, and here) provide a good roadmap. Per the second, I am not so sure. But I was glad to find out about Python creator’s retirement last week. I hear a lot about up-and-coming young engineers, but not about older engineers. Some part of me was relieved that at least some engineers successfully retire.
Work-life balance is for all of us to think about. We, as individuals, need to find the right balance for ourselves. I like my line-of-work, and I want to do it well. I happen to like my employer, as well. But I won’t sacrifice my evenings or weekends for it.
I had a hard time understanding this article since I haven’t had to think about performance deeply. This article is essentially about creating resource hints for data and code, a step forward from HTML’s resource hints. I hope the instrumentation be rather straightforward; otherwise, I fear I won’t care enough.
The idea isn’t new. If our product is not delightful and, thus, not viable in the market, we should strive to be delightful enough. However, I do think it is useful to have a different vocabulary to emphasize the point.
AlphaGo beat Lee Sedol less than four years ago. When DeepMind announced that they would go after Starcraft II, I wondered how long it would take to create an AI capable of beating top human players under the similar interface constraints. DeepMind achieved that a little over three and a half years. This is a fantastic feat, considering the enormous problem space, and imperfect information.
I was fortunate to go to the GraphQL Summit in San Francisco. It has been a while since I went to a conference. And it was good to be in that immersive environment (though I wasn’t able to make a meaningful connection). The talks helped me organize the fragmented GraphQL knowledge in my head. To remember and share what I learned, I wrote a review of the Summit here. I am going to QCon next week, which I very much look forward to as well.
I wholeheartedly agree that a great decision is not an outcome, but a process. I don’t think the acronym works, but still, there are some excellent questions to ask when making a hard, irreversible decision: by when should I make the decision? What are my options? How should I make the decision? How will it look like ten months from now?
When I was asked if I would choose Redux again for a new project after my Redux talk, I said I would use GraphQL. GraphQL clients solve Redux’s complexities, such as normalization, cache persistence, and complex scaffolding, out of the box. Apollo Client especially made my life easy. I am looking forward to the coming performance optimization in this release.
I never considered any other smaller public clouds in my previous projects. So I was surprised when Corey Quinn, whose newsletter and consulting work is solely about AWS, recommended DigitalOcean for simpler, smaller scenarios.
I love React hooks, especially compared to the alternatives like high-order components, or class components. The type system makes so much more sense. I was only unhappy that the hooks were not that testable, but this library I found out this week helped me a lot.
I loved this issue of Andrew Ng’s newsletter very much. It overviews the significant issues AI practitioners face: the possibilities of Rogue AI, Public Trust Erosion, Surveillance, Bias in AI, Job Safety, and AI Winter.
Talks were primarily divided into two categories: client-side and server-side. I mostly went to the client-side ones. Of those I went to, I enjoyed Fine-Tuning Apollo Client Caching for Your Data Graph, Client-side GraphQL at scale, and, The GraphQL developer experience the most. The followings are my notes on the talks I attended. I hope the notes guide you to find something interesting.
From the start, Danielle made a good point about the real benefit of GraphQL. It’s not just about minimizing payload or reducing round trips. It’s about the productivity boost from the integrated experience with typed API, normalization, and intelligent caching. React, Prettier, and VS Code solved the challenges of component structure, formatting, and type intelligence. Now GraphQL solves the next big problem, data fetching. I like that she went into the whys of GraphQL and also gave an end-to-end view of the tooling. I recommend it to those whose GraphQL journey is just starting.
Ben talked about the new features in the upcoming Apollo Client 3. I found the material very relevant because my team is already seeing a huge performance bottleneck from Apollo Cache. There were several exciting features: Garbage collection, declarative cache config (though it doesn’t statically check the config yet), and improved pagination handling. Since most of the features are about performance, the talk is meaningful for those using Apollo Client at scale already.
As a frontend developer, it can be frustrating trying to adopt GraphQL since you find yourself dependent on backend counterparts. Michelle talks about how you can go around the inertia by using a GraphQL middleware (or BFF). Though I believe client-side resolver is the lighter weight approach, it was inspiring to see her org, eventually turning around thanks to the superior developer experience. She then continues to talk about her plan to adopt a federation. This talk is appropriate for those interested in figuring out the GraphQL adoption strategy.
Apollo Lounge (not a talk)
I spent an hour in between talks to talk to Hugh Willson, one of the Apollo engineers behind Apollo Client 3, about the performance bottleneck I saw in the beta release. The problem was that the Apollo Client took a long time to respond to a large query response (a tree of about ~2000 objects) even with the denormalization turned off. Due to the time constraint, we didn’t get to the bottom of the issue. But it was nice to see how an Apollo engineer goes about debugging the client and also get reassured that my configuration was not a problem.
After seeing Danielle’s talk, Steven’s talk didn’t feel new to me. Especially because I am following the development process he outlined almost precisely. But if you ever wonder how all these generated types (whether they are from Apollo Tooling or GraphQL Code Generator) fit into your type system, this talk is for you.
The most entertaining talk I have ever been to. Alex made GraphQL subscription via WebSocket unforgettable. However, as I went to the talk expecting to see GraphQL streaming (a misunderstanding on my part), I ended up getting a little disappointed. If you are building a real-time app, watch this talk when it becomes available.
Even though GraphQL’s governance mostly feels irrelevant, it matters to all of us. Orta talked through how the current GraphQL Foundation came about and how he saw through the changes. This talk isn’t for everyone, but if you like to contribute to the spec one day, watch this.
The whole talk felt like a sales pitch of his company, OneGraph. But Daniel indeed showcased many inspiring tools leveraging: a point-and-click GUI to build a query, an Excel plugin to import GraphQL data into a spreadsheet, and a type checker for queries embedded in markdown documents. The talk was more inspirational than useful.
Shopify’s admin app has ~1000 GraphQL queries and ~700 entities. The company came up with a couple of useful libraries to mitigate this complexity. One library filled the gap in Apollo Client’s type system using collocated d.ts for GraphQL documents, which I found smart. Another autogenerated mock data based on GraphQL schema. I plan to adopt both of them at my current projects. If you are pressed for time, you don’t need to watch the talk since the documentation on the libraries do an excellent job of explaining what they do.
Edit: All videos can now be found here. I linked the videos to my review as well.
It was a stressful week for me. I ended up having 6 out of 9 scheduled chats, with both hits and misses. While I learned quite a bit and met some interesting people I would like to keep in touch going forward, I felt burned out by the end of the week. Devoting this much time hampered both my work and personal life. I will probably allocate less time and be more selective in accepting 1:1s in the coming month.
Anyhows, this week covers quite a few topics on infrastructure. I hope you enjoy them! I am going to get some more rest…
Remote workers at the nascent stage did not work out despite the commitment from the founding team to build a remote team. After setting up a needed structure for clear direction and communication, they were able to perform at a high level.
The author’s assumption of general mediocrity and complacency is not my cup of tea. I also believe some form of pushing information (or status meetings) can lead to serendipitous findings. But I do agree that employees should be educated on what’s expected of them and how their work impacts the business. (See open-book management)
I pushed to achieve Continuous Integration/Continuous Deployment wherever I worked. Continuously deploying is not always the best course action, and you need to make a risk/reward tradeoff. How likely will this change cause failures? How impactful will the failures be? If the deployment at the given moment is not worthwhile, there is no shame in waiting for the right time.
Serverless and JAM stack are gaining significant steam thanks to their “no-code” architecture. They may not be appropriate for large tech companies, but they provide easy wins to the resource-constrained.
I never thought of this, but I can see that the number of schemata keeps increasing over time in the event-driven architecture, which could make maintenance a nightmare. Schema Registry is a solution where you can store the schemata and load them to parse a JSON per the stored schema dynamically.
This week, I have 7 1:1s with strangers to talk about their careers and mine. I feel fortunate to have these opportunities to give and learn. Hopefully, some will evolve into long-term, mutually-beneficial relationships.
You can think of tech debt as how you think of financial debt. Just as you would sometimes finance your investment via bank loans, you can pay for your product bets using the tech debt. It’s apt that the VP of Product at Capital One write this article.
A very cool project to leverage HTTP 2 features (multiplexing and server-push) to solve many problems GraphQL aims to solve: over/under fetching, and the n+1 problem. The project also reuses HTTP caching, which GraphQL can only use with predefined queries.
I got two things that changed my thinking on remote work. First, Silicon Valley may have the best engineering talents, but the good ones are everywhere. Second, remote work is getting more accessible, thanks to the new tools. I hope to work in a completely remote environment to get better at remote work in the next few years.
I always thought games are the worst kind of software to develop due to a marketing-driven, fixed deadline, and the inability to verify ideas. But contemporary games work more like SaaS products, which could remove some of the pressure.
Meetup users came out hard against the service’s plan to charge them, which was expected. But I am still surprised that the disgruntled users are now building open-source alternatives. This series of events shows how easy and cheap it is to start new services.
This past week, I couldn’t let go of how China threw its weight against the NBA and Blizzard. When the money and the values collided, the organizations’ knee jerk reactions were to give up their values. It was unbelievable how fast they tried to appease their Chinese fans.
This series of events reminds me that leaders need more than technical or management skills. We need values as our guiding principles. Throughout our careers, we will be put into a position where we need to make similar tough calls. And it’s not just international politics; we need to think about racial and gender inequality, global warming, privacy, and more. The choices we face may not be as visible. But the tradeoffs and the consequences will be just as real. It will be crucial for all of us to have values we can be proud of and base our actions on those values.
