という点についてオリビエ・ブランシャールとリカルド・ライスが議論している。具体的には、利上げでインフレを下げる際に失業率が上昇するのは副作用に過ぎず、失業率上昇という経路を通じてインフレが低下するわけではない、とリカルド・ライスがデビッド・ベックワースとの対談で述べ、その言葉をベックワースがツイッターで紹介したところ、ブランシャールが反応して以下のようにツイートしている。 Dear Ricardo, I am puzzled. For me, the increase in unemployment is causal, not a side effect, for inflation. Do you mean to say that, if we could avoid the side effect, we could decrease inflation without higher

December 17, 2023 Native mobile apps are optional for B2B startups in 2024 I continue to see new B2B software startups struggle with native mobile apps. Consumer software makers can usually start by going all-in on a single platform, but for business tools, that’s rarely an option. So they must face the tall task of tackling web, iOS, and Android at the same time. Hence the proliferation of toolki

Why I use Astro
Why I use Astro Dec 13, 2023 I’ve been thinking about writing this since a few months ago when some prominent people in the industry were battling “why I use Next.js” vs “why I use Remix”. Now, I don’t try to claim that this is the thing you should do. It’s just a collection of thoughts on why I use Astro. What works for me. And what works for me might not be what works for you. That said, I’ve be

What happened to Vivaldi Social? | Thomas Pike’s other blog
On Saturday 8 July 2023, user accounts started disappearing from the Vivaldi Social Mastodon instance. What was going on, how did this happen, and what were the consequences? This is a very long blog post, but to be fair, this was also to be a very long weekend. If you want to skip to the conclusion, there’s a TL;DR (too long; didn’t read) section at the end.

Today we’re excited to announce the release of TypeScript 5.5! If you’re not familiar with TypeScript, it’s a language that builds on top of JavaScript by making it possible to declare and describe types. Writing types in our code allows us to explain intent and have other tools check our code to catch mistakes like typos, issues with null and undefined, and more. Types also power TypeScript’s edi

Was Rust Worth It?
A few years ago, I dropped everything to focus 100% on WebAssembly. At the time, Rust had the best support for compiling into WebAssembly, and the most full-featured WebAssembly runtimes were Rust-based. Rust was the best option on the menu. I jumped in, eager to see what all the hype was about. Since then, I (along with some other awesome people) built Wick, an application framework and runtime t

Prism in 2024
In Ruby 3.3.0, a new standard library was added to CRuby called Prism. Prism is a parser for the Ruby language, exposed as both a C library (optionally usable by CRuby) and a Ruby library (usable as a Ruby gem). The Prism project represents many person-years worth of effort, and is the result of a collaboration between Shopify, CRuby core contributors, other Ruby implementation authors, and Ruby t

No offense to the creator of YAML, but: The fact that it became one of the de-facto standards for cloud tooling is an absolutely damning statement about the state of the industry.I get that XML is about as sexy as mainframes, and that a lot of folks here probably have PTSD from working with Java/Spring web apps, but YAML is about the worst of all worlds.

Cloudflare took down our website after trying to force us to pay 120k$ within 24h
TL;DR: We've been on the Cloudflare Business plan ($250/month) for years. They suddenly contacted us and asked us to either pay them $120k up front for one year of Enterprise within 24 hours or they would take down all of our domains. While this escalated up our business we had 3 sales calls with them, trying to figure out what was happening and how to reach a reasonable contract in a week. When w
Coroutines and effects
For the past few months I’ve been mulling over some things that Russell Johnston made me realize about the relationship between effect systems and coroutines. You can read more of his thoughts on this subject here, but he made me realize that effect systems (like that found in Koka) and coroutines (like Rust’s async functions or generators) are in some ways isomorphic to one another.

jq 1.7 | Hacker News
This is great, JQ is brilliant.I love JQ so much we implemented a subset of JQ in Clojure so that our users could use it to munge/filter data in our product (JVM and browser based Kafka tooling). One of the most fun coding pieces I've done, though I am a bit odd and I love writing grammars (big shoutout to Instaparse![1]). I learned through my implementation that JQ is a LISP-2[2] which surprised
If you’ve been making websites for years, you know how frustrating it was to lay out a web page with CSS floats. Managing sizes and placement was tedious and time consuming. Being creative was often impossible. CSS Grid greatly eased that pain with Grid Level 1 in 2017, and now with Grid Level 2, aka Subgrid. But even with the powerful CSS of today, not every layout imaged by designers is possible
Effective TypeScript › The Saga of the Closure Compiler, and Why TypeScript Won
Here's something that makes me feel old: in just six months, Gmail will celebrate its 20th anniversary. If you weren't actively developing web sites at the time, it's hard to capture just how revolutionary it was. This was a time when JavaScript was held in almost universally low regard. The idea that you could build a sophisticated web app using it was mind-boggling. But it clearly worked and it
