Google published Zanzibar: Google’s Consistent, Global Authorization System in 2019. It describes a system for authorization – enforcing who can do what – which maxes out both flexibility and scalability. Google has lots of different apps that rely on Zanzibar, and bigger scale than practically any other company, so it needed Zanzibar. The Zanzibar paper made quite a stir. There are at least four companies that advertise products as being inspired by or based on Zanzibar. It says a lot for everyone to loudly reference this paper on homepages and marketing materials: companies aren’t advertising their own innovation as much as simply saying they’re following the gospel. A short list of companies & OSS products I found: Companies WorkOS FGA Authzed auth0 FGA Ory Permify Open source Ory Keto (Go) Warrant (Go) probably the basis for WorkOS FGA, since WorkOS acquired Warrant. SpiceDB (Go) the basis for Authzed. Permify (Go) OpenFGA (Go) the basis of auth0 FGA. I read the paper, and have a few notes, but the Google Zanzibar Paper, annotated by AuthZed is the same thing from a real domain expert (albeit one who works for one of these companies), so read that too, or instead. Features My brief summary is that the Zanzibar paper describes the features of the system succinctly, and those features are really appealing. They’ve figured out a few primitives from which developers can build really flexible authorization rules for almost any kind of application. They avoid making assumptions about ID formats, or any particular relations, or how groups are set up. It’s abstract and beautiful. The gist of the system is: Objects: things in your data model, like documents Users: needs no explanation Namespaces: for isolating applications Usersets: groups of users Userset rewrite rules: allow usersets to inherit from each other or have other kinds of set relationships Tuples, which are like (object)#(relation)@(user), and are sort of the core ‘rule’ construct for saying who can access what There’s then a neat configuration language which looks like this in an example: name: "doc" relation { name: "owner"} relation { name: "editor" userset_rewrite { union { child { _this f } } child { computed_userset { relation: "owner" } } relation { name: "viewer" userset_rewrite { union { child {_this f} } child { computed_userset & relation: "editor" 3 } child { tuple_to_userset { tupleset { relation: "parent" } computed_userset { object: $TUPLE_USERSET_OBJECT # parent folder relation: "viewer" } } } } } } It’s pretty neat. At this point in the paper I was sold on Zanzibar: I could see this as being a much nicer way to represent authorization than burying it in a bunch of queries. Specifications & Implementation details And then the paper discusses specifications: how much scale it can handle, and how it manages consistency. This is where it becomes much more noticeably Googley. So, with Google’s scale and international footprint, all of their services need to be globally distributed. So Zanzibar is a distributed system, and it is also a system that needs good consistency guarantees so that it avoid the “new enemy” problem, nobody is able to access resources that they shouldn’t, and applications that are relying on Zanzibar can get a consistent view of its data. Pages 5-11 are about this challenge, and it is a big one with a complex, high-end solution, and a lot of details that are very specific to Google. Most noticeably, Zanzibar is built with Spanner Google’s distributed database, and Spanner has the ability to order timestamps using TrueTime, which relies on atomic clocks and GPS antennae: this is not standard equipment for a server. Even CockroachDB, which is explicitly modeled off of Spanner, can’t rely on having GPS & atomic clocks around so it has to take a very different approach. But this time accuracy idea is pretty central to Zanzibar’s idea of zookies, which are sort of like tokens that get sent around in its API and indicate what time reference the client expects so that a follow-up response doesn’t accidentally include stale data. To achieve scalability, Zanzibar is also a multi-server architecture: there are aclservers, watchservers, a Leopard indexing system that creates compressed skip list-based representations of usersets. There’s also a clever solution to the caching & hot-spot problem, in which certain objects or tuples will get lots of requests all at once so their database shard gets overwhelmed. Conclusions Zanzibar is two things: A flexible, relationship-based access control model A system to provide that model to applications at enormous scale and with consistency guarantees My impressions of these things match with AuthZed’s writeup so I’ll just quote & link them: There seems to be a lot of confusion about Zanzibar. Some people think all relationship-based access control is “Zanzibar”. This section really brings to light that the ReBAC concepts have already been explored in depth, and that Zanzibar is really the scaling achievement of bringing those concepts to Google’s scale needs. link And Zookies are very clearly important to Google. They get a significant amount of attention in the paper and are called out as a critical component in the conclusion. Why then do so many of the Zanzibar-like solutions that are cropping up give them essentially no thought? link I finished the paper having absorbed a lot of tricky ideas about how to solve the distributed-consistency problems, and if I were to describe Zanzibar, those would be a big part of the story. But maybe that’s not what people mean when they say Zanzibar, and it’s more a description of features? I did find that Permify has a zookie-like Snap Token, AuthZed/SpiceDB has ZedTokens, and Warrant has Warrant-Tokens. Whereas OpenFGA doesn’t have anything like zookies and neither does Ory Keto. So it’s kind of mixed on whether these Zanzibar-inspired products have Zanzibar-inspired implementations, or focus more on exposing the same API surface. For my own needs, zookies and distributed consistency to the degree described in the Zanzibar paper are overkill. There’s no way that we’d deploy a sharded five-server system for authorization when the main application is doing just fine with single-instance Postgres. I want the API surface that Zanzibar describes, but would trade some scalability for simplicity. Or use a third-party service for authorization. Ideally, I wish there was something like these products but smaller, or delivered as a library rather than a server.
I watched a large part of All Watched Over By Machines of Loving Grace this month. This also counts as a “listening” item, because the theme song, “Baby Love Child” by Pizzicato Five, is also spectacular. Guitar Moves is a good series of interviews by Matt Sweeney, who I mostly know via his involvement in Bonnie Prince Billy. It’s a really cool format. I like how he interviews guitarists with recognizable sounds, and you get to see how little they need to play to sound just like themselves. The episode with St. Vincent is excellent too: she’s one of my guitar heroes: check out the guitar solo in Just The Same But Brand New, or her version of Dig a Pony. I also watched No Other Land. Everyone should watch No Other Land. AI thoughts roundup I don’t have a conclusion. Really, that’s my current state: ambivalence. I acknowledge that these tools are incredibly powerful, I’ve even started incorporating them into my work in certain limited ways (low-stakes code like POCs and unit tests seem like an ideal use case), but I absolutely hate them. I hate the way they’ve taken over the software industry, I hate how they make me feel while I’m using them, and I hate the human-intelligence-insulting postulation that a glorified Excel spreadsheet can do what I can but better. Nolan Lawson: AI ambivalence As I always say, the purpose of the system is what it does. Or, in this case, how I think about AI stuff is mostly affected by how people use AI stuff, and how people use AI stuff is a real mixed bag. There’s the tidal wave of spam, the aesthetic of fascism, the low-effort marketing materials with nonsense images, the non-consensual AI porn. I see all of the bad stuff every day both online and in the odd subway ad. The good stuff seems pretty theoretical, though: the press releases about AI-driven medical advances never seem to break into the real world. The stories about engineers 10x’ing their ability seem pretty mixed: we’re already at the hangover-and-regret phase with programmers bemoaning how they’ve generated so much slop and lost so much knowledge. Anyway, I’m mildly optimistic about the potential! But it’s a lot like crypto in that you could theoretically use the technology for something good but most people loudly used it for bad stuff, and people including me judged it based on what it did. AI has to start doing some good stuff soon. Potential isn’t enough. I think one thing chatGPT’s invention has revealed is how many people - including some very important people in society - find just basic reading and writing to be laborious and cumbersome to perform, and how oddly closely that type of strained literacy correlates with having other shitty opinions. From mtsw on Bluesky, about this story about Andrew Cuomo using ChatGPT to half-assedly write a policy platform. Right off the bat I should say that judging people for their level of literacy reeks of classism and so on. My own ability to read & write has a lot to do with my place in society: I went to good schools, had a stable home life, and smart parents. However, “the way that society was set up” kind of evened this out. Extremely social people with cultural capital and chiseled jawlines and biceps would get their rewards, and people like… myself, we would get rewarded for literacy and critical thinking. When one group needed the other, it was usually some kind of payment or partnership: Cuomo pays his scriptwriter, the TV show creator pays the actors. And some people can do both sides of the equation. But LLMs definitely indicate that people do not like this deal. Whew, they don’t like writing, but they also don’t like paying the writers or reading what they write. Maybe they could rejigger the system so that they could do it all. They have ideas for music and art but no interest in learning about music, practicing instruments, going to art school, or concentrating on a task for a long time, so why not generate it all? Why not, well - there are reasons, those reasons being that the generated output usually passes their own vibe check but once someone who looks closely at things or reads all the words encounters it, everyone points at the slop and it’s embarrassing. (Cuomo will never be embarrassed) Plus, you’re always going to get average results by asking a device that is incapable of creativity or thought. Also, you’ll miss out on the human experience of creating. And you’ll be indirectly feeding output data into training data for future LLMs, consequentially making their output worse. (Cuomo does not care about consequences) Colophon update I’ve moved the images for this website to Bunny (that’s an affiliate link, here’s a non-affiliate link if that’s what you prefer). When I initially moved my photos to this website, I set them up with Amazon S3 for storage and CloudFront to serve them with a CDN. Using AWS is painful for me, so I moved them to Cloudflare R2, which is Cloudflare’s equivalent to S3, and Cloudflare as a CDN. Thanks to owning my own domains, swapping out image hosts is pretty quick: switching to Bunny took all of five minutes. So what’s the deal with Bunny? Partly I’ve become a little more negative on Cloudflare and R2: I think Cloudflare’s technology is neat, but R2 has iffy reliability and Cloudflare has iffy politics. I’m also intrigued by diversifying my dependencies geographically. Bunny is a Slovenian company, and my email is from an Australian company. This probably won’t have any practical effect, but it feels kind of good for obvious reasons to even minutely hedge my bets here. So far Bunny has been great. They don’t support the S3 protocol but they do support SFTP, which works just as well for my purposes and works great with the beautiful Transmit app. Before, with R2, I was using the significantly less beautiful Cyberduck application because Cloudflare R2 doesn’t support all of the S3 protocol. It seems to be just as fast as Cloudflare was, too. And I’m somewhat reassured by the prospect of paying Bunny. I don’t like the feeling of getting “free” services like I can from Cloudflare. I want that customer relationship. Reading Then again, pop culture is powerful, and even the dumbest marketing both affects and reflects it. Busch Light’s can holder shaped like a cup that holds beer is dumb, which is fine, because most beer promos are. But the fact that the brand frames it as a functional, masculine alternative to Stanley’s H2.0 Flowstate affirms a similarly retrograde outlook on gender roles to the one that young American men are seeking out on the political right. From my friend Dave’s article about Busch Light’s weird attempt to riff on the Stanley Tumbler trend. I was once a loyal listener of the Chapo Trap House podcast, but fell off of it in 2020 when their support of Bernie Sanders led them to be jerks about Elizabeth Warren. But reading this Vanity Fair article about the cohosts of the podcast endeared them to me a bit. “Like to thank” is linguistic phlegm. “I’d like to thank the Academy.” They’d “like to thank” me. Well I’d like to be 6’3” and drive a G Wagon, thanks. I’d like you to accept my novella. I’d like to quit paying three dollars to Submittable every time I want to send a story out. The world is full of actions I would like to do. The most direct way to say thank you is just to say it: “thank you, name, for doing X.” “I’d like to thank” is a performative thanks, a thanks with a smirk and a blink, eyeing for extra credit. Just because people say it in their award show acceptance speeches doesn’t mean you should say it, too. In fact, that’s the reason you shouldn’t say it. Loved this article “Close reading my rejections” from friend of the blog Barrett Hathcock.
Reading Whether it’s cryptocurrency scammers mining with FOSS compute resources or Google engineers too lazy to design their software properly or Silicon Valley ripping off all the data they can get their hands on at everyone else’s expense… I am sick and tired of having all of these costs externalized directly into my fucking face. Drew DeVault on the annoyance and cost of AI scrapers. I share some of that pain: Val Town is routinely hammered by some AI company’s poorly-coded scraping bot. I think it’s like this for everyone, and it’s hard to tell if AI companies even care that everyone hates them. And perhaps most recently, when a person who publishes their work under a free license discovers that work has been used by tech mega-giants to train extractive, exploitative large language models? Wait, no, not like that. Molly White wrote a more positive article about the LLM scraping problem, but I have my doubts about its positivity. For example, she suggests that Wikimedia’s approach with “Wikimedia Enterprise” gives LLM companies a way to scrape the site without creating too much cost. But that doesn’t seem like it’s working. The problem is that these companies really truly do not care. Harberger taxes represent an elegant theoretical solution that fails in practice for immobile property. Just as mobile home residents face exploitation through sudden ground rent increases, property owners under a Harberger system would face similar hold-up problems. This creates an impossible dilemma: pay increasingly burdensome taxes or surrender investments at below-market values. Progress and Poverty, a blog about Georgism, has this post about Herberger taxes, which are a super neat idea. The gist is that you would be in charge of saying how much your house is worth, but the added wrinkle is that by saying a price you are bound to be open to selling your house at that price. So if you go too low, someone will buy it, or too high, and you’re paying too much in taxes. It’s clever but doesn’t work, and the analysis points to the vital difference between housing and other goods: that buying, selling, and moving between houses is anything but simple. I’ve always been a little skeptical of the line that the AI crowd feels contempt for artists, or that such a sense is particularly widespread—because certainly they all do not!—but it’s hard to take away any other impression from a trend so widely cheered in its halls as AI Ghiblification. Brian Merchant on the OpenAI Studio Ghibli ‘trend’ is a good read. I can’t stop thinking that AI is in danger of being right-wing coded, the examples of this, like the horrifying White House tweet mentioned in that article, are multiplying. I feel bad when I recoil to innocent usage of the tool by good people who just want something cute. It is kind of fine, on the micro level. But with context, it’s so bad in so many ways. Already the joy and attachment I’ve felt to the graphic style is fading as more shitty Studio Ghibli knockoffs have been created in the last month than in all of the studio’s work. Two days later, at a state dinner in the White House, Mark gets another chance to speak with Xi. In Mandarin, he asks Xi if he’ll do him the honor of naming his unborn child. Xi refuses. Careless People was a good read. It’s devastating for Zuckerberg, Joel Kaplan, and Sheryl Sandberg, as well as a bunch of global leaders who are eager to provide tax loopholes for Facebook. Perhaps the only person who ends the book as a hero is President Obama, who sees through it all. In a March 26 Slack message, Lavingia also suggested that the agency should do away with paper forms entirely, aiming for “full digitization.” “There are over 400 vet-facing forms that the VA supports, and only about 10 percent of those are digitized,” says a VA worker, noting that digitizing forms “can take years because of the sensitivity of the data” they contain. Additionally, many veterans are elderly and prefer using paper forms because they lack the technical skills to navigate digital platforms. “Many vets don’t have computers or can’t see at all,” they say. “My skin is crawling thinking about the nonchalantness of this guy.” Perhaps because of proximity, the story that Sahil Lavingia has been working for DOGE seems important. It was a relief when a few other people noticed it and started retelling the story to the tech sphere, like Dan Brown’s “Gumroad is not open source” and Ernie Smith’s “Gunkroad”, but I have to nitpick on the structure here: using a non-compliant open source license is not the headline, collaborating with fascists and carelessly endangering disabled veterans is. Listening Septet by John Carroll Kirby I saw John Carroll Kirby play at Public Records and have been listening to them constantly ever since. The music is such a paradox: the components sound like elevator music or incredibly cheesy jazz if you listen to a few seconds, but if you keep listening it’s a unique, deep sound. Sierra Tracks by Vega Trails More new jazz! Mammoth Hands and Portico Quartet overlap with Vega Trails, which is a beautiful minimalist band. Watching This short video with John Wilson was great. He says a bit about having a real physical video camera, not just a phone, which reminded me of an old post of mine, Carrying a Camera.
I used to make little applications just for myself. Sixteen years ago (oof) I wrote a habit tracking application, and a keylogger that let me keep track of when I was using a computer, and generate some pretty charts. I’ve taken a long break from those kinds of things. I love my hobbies, but they’ve drifted toward the non-technical, and the idea of keeping a server online for a fun project is unappealing (which is something that I hope Val Town, where I work, fixes). Some folks maintain whole ‘homelab’ setups and run Kubernetes in their basement. Not me, at least for now. But I have been tiptoeing back into some little custom tools that only I use, with a focus on just my own computing experience. Here’s a quick tour. Hammerspoon Hammerspoon is an extremely powerful scripting tool for macOS that lets you write custom keyboard shortcuts, UIs, and more with the very friendly little language Lua. Right now my Hammerspoon configuration is very simple, but I think I’ll use it for a lot more as time progresses. Here it is: hs.hotkey.bind({"cmd", "shift"}, "return", function() local frontmost = hs.application.frontmostApplication() if frontmost:name() == "Ghostty" then frontmost:hide() else hs.application.launchOrFocus("Ghostty") end end) Not much! But I recently switched to Ghostty as my terminal, and I heavily relied on iTerm2’s global show/hide shortcut. Ghostty doesn’t have an equivalent, and Mikael Henriksson suggested a script like this in GitHub discussions, so I ran with it. Hammerspoon can do practically anything, so it’ll probably be useful for other stuff too. SwiftBar I review a lot of PRs these days. I wanted an easy way to see how many were in my review queue and go to them quickly. So, this script runs with SwiftBar, which is a flexible way to put any script’s output into your menu bar. It uses the GitHub CLI to list the issues, and jq to massage that output into a friendly list of issues, which I can click on to go directly to the issue on GitHub. #!/bin/bash # <xbar.title>GitHub PR Reviews</xbar.title> # <xbar.version>v0.0</xbar.version> # <xbar.author>Tom MacWright</xbar.author> # <xbar.author.github>tmcw</xbar.author.github> # <xbar.desc>Displays PRs that you need to review</xbar.desc> # <xbar.image></xbar.image> # <xbar.dependencies>Bash GNU AWK</xbar.dependencies> # <xbar.abouturl></xbar.abouturl> DATA=$(gh search prs --state=open -R val-town/val.town --review-requested=@me --json url,title,number,author) echo "$(echo "$DATA" | jq 'length') PR" echo '---' echo "$DATA" | jq -c '.[]' | while IFS= read -r pr; do TITLE=$(echo "$pr" | jq -r '.title') AUTHOR=$(echo "$pr" | jq -r '.author.login') URL=$(echo "$pr" | jq -r '.url') echo "$TITLE ($AUTHOR) | href=$URL" done Tampermonkey Tampermonkey is essentially a twist on Greasemonkey: both let you run your own JavaScript on anybody’s webpage. Sidenote: Greasemonkey was created by Aaron Boodman, who went on to write Replicache, which I used in Placemark, and is now working on Zero, the successor to Replicache. Anyway, I have a few fancy credit cards which have ‘offers’ which only work if you ‘activate’ them. This is an annoying dark pattern! And there’s a solution to it - CardPointers - but I neither spend enough nor care enough about points hacking to justify the cost. Plus, I’d like to know what code is running on my bank website. So, Tampermonkey to the rescue! I wrote userscripts for Chase, American Express, and Citi. You can check them out on this Gist but I strongly recommend to read through all the code because of the afore-mentioned risks around running untrusted code on your bank account’s website! Obsidian Freeform This is a plugin for Obsidian, the notetaking tool that I use every day. Freeform is pretty cool, if I can say so myself (I wrote it), but could be much better. The development experience is lackluster because you can’t preview output at the same time as writing code: you have to toggle between the two states. I’ll fix that eventually, or perhaps Obsidian will add new API that makes it all work. I use Freeform for a lot of private health & financial data, almost always with an Observable Plot visualization as an eventual output. For example, when I was switching banks and one of the considerations was mortgage discounts in case I ever buy a house (ha 😢), it was fun to chart out the % discounts versus the required AUM. It’s been really nice to have this kind of visualization as ‘just another document’ in my notetaking app. Doesn’t need another server, and Obsidian is pretty secure and private.

The world is waking to the fact that talk therapy is neither the only nor the best way to cure a garden-variety petite depression. Something many people will encounter at some point in their lives. Studies have shown that exercise, for example, is a more effective treatment than talk therapy (and pharmaceuticals!) when dealing with such episodes. But I'm just as interested in the role building competence can have in warding off the demons. And partly because of this meme: I've talked about it before, but I keep coming back to the fact that it's exactly backwards. That signing up for an educational quest into Linux, history, or motorcycle repair actually is an incredibly effective alternative to therapy! At least for men who'd prefer to feel useful over being listened to, which, in my experience, is most of them. This is why I find it so misguided when people who undertake those quests sell their journey short with self-effacing jibes about how much an unattractive nerd it makes them to care about their hobby. Mihaly Csikszentmihalyi detailed back in 1990 how peak human happiness arrives exactly in these moments of flow when your competence is stretched by a difficult-but-doable challenge. Don't tell me those endorphins don't also help counter the darkness. But it's just as much about the fact that these pursuits of competence usually offer a great opportunity for community as well that seals the deal. I've found time and again that people are starved for the kind of topic-based connections that, say, learning about Linux offers in spades. You're not just learning, you're learning with others. That is a time-tested antidote to depression: Forming and cultivating meaningful human connections. Yes, doing so over the internet isn't as powerful as doing it in person, but it's still powerful. It still offers community, involvement, and plenty of invitation to carry a meaningful burden. Open source nails this trifecta of motivations to a T. There are endless paths of discovery and mastery available. There are tons of fellow travelers with whom to connect and collaborate. And you'll find an unlimited number of meaningful burdens in maintainerships open for the taking. So next time you see that meme, you should cheer that the talk therapy table is empty. Leave it available for the severe, pathological cases that exercise and the pursuit of competence can't cure. Most people just don't need therapy, they need purpose, they need competence, they need exercise, and they need community.
The excellent-but-defunct blog Programming in the 21st Century defines "puzzle languages" as languages were part of the appeal is in figuring out how to express a program idiomatically, like a puzzle. As examples, he lists Haskell, Erlang, and J. All puzzle languages, the author says, have an "escape" out of the puzzle model that is pragmatic but stigmatized. But many mainstream languages have escape hatches, too. Languages have a lot of properties. One of these properties is the language's capabilities, roughly the set of things you can do in the language. Capability is desirable but comes into conflicts with a lot of other desirable properties, like simplicity or efficiency. In particular, reducing the capability of a language means that all remaining programs share more in common, meaning there's more assumptions the compiler and programmer can make ("tractability"). Assumptions are generally used to reason about correctness, but can also be about things like optimization: J's assumption that everything is an array leads to high-performance "special combinations". Rust is the most famous example of mainstream language that trades capability for tractability.1 Rust has a lot of rules designed to prevent common memory errors, like keeping a reference to deallocated memory or modifying memory while something else is reading it. As a consequence, there's a lot of things that cannot be done in (safe) Rust, like interface with an external C function (as it doesn't have these guarantees). To do this, you need to use unsafe Rust, which lets you do additional things forbidden by safe Rust, such as deference a raw pointer. Everybody tells you not to use unsafe unless you absolutely 100% know what you're doing, and possibly not even then. Sounds like an escape hatch to me! To extrapolate, an escape hatch is a feature (either in the language itself or a particular implementation) that deliberately breaks core assumptions about the language in order to add capabilities. This explains both Rust and most of the so-called "puzzle languages": they need escape hatches because they have very strong conceptual models of the language which leads to lots of assumptions about programs. But plenty of "kitchen sink" mainstream languages have escape hatches, too: Some compilers let C++ code embed inline assembly. Languages built on .NET or the JVM has some sort of interop with C# or Java, and many of those languages make assumptions about programs that C#/Java do not. The SQL language has stored procedures as an escape hatch and vendors create a second escape hatch of user-defined functions. Ruby lets you bypass any form of encapsulation with send. Frameworks have escape hatches, too! React has an entire page on them. (Does eval in interpreted languages count as an escape hatch? It feels different, but it does add a lot of capability. Maybe they don't "break assumptions" in the same way?) The problem with escape hatches In all languages with escape hatches, the rule is "use this as carefully and sparingly as possible", to the point where a messy solution without an escape hatch is preferable to a clean solution with one. Breaking a core assumption is a big deal! If the language is operating as if its still true, it's going to do incorrect things. I recently had this problem in a TLA+ contract. TLA+ is a language for modeling complicated systems, and assumes that the model is a self-contained universe. The client wanted to use the TLA+ to test a real system. The model checker should send commands to a test device and check the next states were the same. This is straightforward to set up with the IOExec escape hatch.2 But the model checker assumed that state exploration was pure and it could skip around the state randomly, meaning it would do things like set x = 10, then skip to set x = 1, then skip back to inc x; assert x == 11. Oops! We eventually found workarounds but it took a lot of clever tricks to pull off. I'll probably write up the technique when I'm less busy with The Book. The other problem with escape hatches is the rest of the language is designed around not having said capabilities, meaning it can't support the feature as well as a language designed for them from the start. Even if your escape hatch code is clean, it might not cleanly integrate with the rest of your code. This is why people complain about unsafe Rust so often. It should be noted though that all languages with automatic memory management are trading capability for tractability, too. If you can't deference pointers, you can't deference null pointers. ↩ From the Community Modules (which come default with the VSCode extension). ↩
I wrote a lot of blog posts over my time at Parse, but they all evaporated after Facebook killed the product. Most of them I didn’t care about (there were, ahem, a lot of status updates and “service reliability announcements”, but I was mad about losing this one in particular, a deceptively casual retrospective of […]
It's only been two months since I discovered the power and joy of this new generation of mini PCs. My journey started out with a Minisforum UM870, which is a lovely machine, but since then, I've come to really appreciate the work of Beelink. In a crowded market for mini PCs, Beelink stands out with their superior build quality, their class-leading cooling and silent operation, and their use of fully Linux-compatible components (the UM870 shipped with a MediaTek bluetooth/wifi card that doesn't work with Linux!). It's the complete package at three super compelling price points. For $289, you can get the EQR5, which runs an 8-core AMD Zen3 5825U that puts out 1723/6419 in Geekbench, and comes with 16GB RAM and 500GB NVMe. I've run Omarchy on it, and it flies. For me, the main drawback was the lack of a DisplayPort, which kept me from using it with an Apple display, and the fact that the SER8 exists. But if you're on a budget, and you're fine with HDMI only, it's a wild bargain. For $499, you can get the SER8. That's the price-to-performance sweet spot in the range. It uses the excellent 8-core AMD Zen4 8745HS that puts out 2595/12985 in Geekbench (~M4 multi-core numbers!), and runs our HEY test suite with 30,000 assertions almost as fast as an M4 Max! At that price, you get 32GB RAM + 1TB NVMe, as well as a DisplayPort, so it works with both the Apple 5K Studio Display and the Apple 6K XDR Display (you just need the right cable). Main drawback is limited wifi/bluetooth range, but Beelink tells me there's a fix on the way for that. For $929, you can get the SER9 HX370. This is the top dog in this form factor. It uses the incredible 12-core AMD Zen5 HX370 that hits 2990/15611 in Geekbench, and runs our HEY test suite faster than any Apple M chip I've ever tested. The built-in graphics are also very capable. Enough to play a ton of games at 1080p. It also sorted the SER8's current wifi/bluetooth range issue. I ran the SER8 as my main computer for a while, but now I'm using the SER9, and I just about never feel like I need anything more. Yes, the Framework Desktop, with its insane AMD Max 395+ chip, is even more bonkers. It almost cuts the HEY test suite time in half(!), but it's also $1,795, and not yet generally available. (But preorders are open for the ballers!). Whichever machine fits your budget, it's frankly incredible that we have this kind of performance and efficiency available at these prices with all of these Beelinks drawing less than 10 watt at idle and no more than 100 watt at peak! So it's no wonder that Beelink has been selling these units like hotcakes since I started talking about them on X as the ideal, cheap Omarchy desktop computers. It's such a symbiotic relationship. There are a ton of programmers who have become Linux curious, and Beelink offers no-brainer options to give that a try at a bargain. I just love when that happens. The perfect intersection of hardware, software, and timing. That's what we got here. It's a Beelink, baby!

“One of the comments that sparked this article,” our founder Paul McMahon told me, “was someone saying, ‘I don’t really want to do networking because it seems kind of sleazy. I’m not that kind of person.’” I guess that’s the key misconception people have when they hear ‘networking.’ They think it’s like some used car salesman kind of approach where you have to go and get something out of the person. That’s a serious error, according to Paul, and it worries him that so many developers share that mindset. Instead, Paul considers networking a mix of making new friends, growing a community, and enjoying serendipitous connections that might not bear fruit until years later, but which could prove to be make-or-break career moments. It’s something that you don’t get quick results on and that doesn’t make a difference at all until it does. And it’s just because of the one connection you happen to make at an event you went to once, this rainy Tuesday night when you didn’t really feel like going, but told yourself you have to go—and that can make all the difference. As Paul has previously shared, he can attribute much of his own career success—and, interestingly enough, his peace of mind—to the huge amount of networking he’s done over the years. This is despite the fact that Paul is, in his own words, “not such a talkative person when it comes to small talk or whatever.” Recently I sat down with Paul to discuss exactly how developers are networking “wrong,” and how they can get it right instead. In our conversation, we covered: What networking really is, and why you need to start ASAP Paul’s top tip for anyone who wants to network Advice for networking as an introvert Online vs offline networking—which is more effective? And how to network in Japan, even when you don’t speak Japanese What is networking, really, and why should you start now? “Sometimes,” Paul explained, “people think of hiring fairs and various exhibitions as the way to network, but that’s not networking to me. It’s purely transactional. Job seekers are focused on getting interviews, recruiters on making hires. There’s no chance to make friends or help people outside of your defined role.” Networking is getting to know other people, understanding how maybe you can help them and how they can help you. And sometime down the road, maybe something comes out of it, maybe it doesn’t, but it’s just expanding your connections to people. One reason developers often avoid or delay networking is that, at its core, networking is a long game. Dramatic impacts on your business or career are possible—even probable—but they don’t come to fruition immediately. “A very specific example would be TokyoDev,” said Paul. “One of our initial clients that posted to the list came through networking.” Sounds like a straightforward result? It’s a bit more complicated than that. “There was a Belgian guy, Peter, whom I had known through the Ruby and tech community in Japan for a while,” Paul explained. “We knew each other, and Peter had met another Canadian guy, Jack, who [was] looking to hire a Ruby developer. “So Peter knew about me and TokyoDev and introduced me to Jack, and that was the founder of Degica, who became one of our first clients. . . . And that just happened because I had known Peter through attending events over the years.” Another example is how Paul’s connection to the Ruby community helped him launch Doorkeeper. His participation in Ruby events played a critical role in helping the product succeed, but only because he’d already volunteered at them for years. “Because I knew those people,” he said, “they wanted to support me, and I guess they also saw that I was genuine about this stuff, and I wasn’t participating in these events with some big plan about, ‘If I do this, then they’re going to use my system,’ or whatever. Again, it was people helping each other out.” These delayed and indirect impacts are why Paul thinks you should start networking right now. “You need to do it in advance of when you actually need it,” he said. “People say they’re looking for a job, and they’re told ‘You could network!’ Yeah, that could potentially help, but it’s almost too late.” You should have been networking a couple years ago when you didn’t need to be doing it, because then you’ve already built up the relationships. You can have this karma you’re building over time. . . . Networking has given me a lot of wealth. I don’t mean so much in money per se, but more it’s given me a safety net. “Now I’m confident,” he said, “that if tomorrow TokyoDev disappeared, I could easily find something just through my connections. I don’t think I’ll, at least in Japan, ever have to apply for a job again.” “I think my success with networking is something that anyone can replicate,” Paul went on, “provided they put in the time. I don’t consider myself to be especially skilled in networking, it’s just that I’ve spent over a decade making connections with people.” How to network (the non-sleazy way) Paul has a fair amount of advice for those who want to network in an effective, yet genuine fashion. His first and most important tip: Be interested in other people. Asking questions rather than delivering your own talking points is Paul’s number one method for forging connections. It also helps avoid those “used car salesman” vibes. “ That’s why, at TokyoDev,” Paul explained, “we typically bar recruiters from attending our developer events. Because there are these kinds of people who are just going around wanting to get business cards from everyone, wanting to get their contact information, wanting to then sell them on something later. It’s quite obvious that they’re like that, and that leads to a bad environment, [if] someone’s trying to sell you on something.” Networking for introverts The other reason Paul likes asking questions is that it helps him to network as an introvert. “That’s actually one of the things that makes networking easier for someone who isn’t naturally so talkative. . . . When you meet new people, there are some standard questions you can ask them, and it’s like a blank slate where you’re filling in the details about this person.” He explained further that going to events and being social can be fun for him, but he doesn’t exactly find it relaxing. “When it comes to talking about something I’m really interested in, I can do it, but I stumble in these social situations. Despite that, I think I have been pretty successful when it comes to networking.” “What has worked well for me,” he went on, “has been putting myself in those situations that require me to do some networking, like going to an event.” Even if you aren’t that proactive, you’re going to meet a couple of people there. You’re making more connections than you would if you stayed home and played video games. The more often you do it, the easier it gets, and not just because of practice: there’s a cumulative effect to making connections. “Say you’re going to an event, and maybe last time you met a couple of people, you could just say ‘Hi’ to those people again. And maybe they are talking with someone else they can introduce you to.” Or, you can be the one making the introductions. “What has also worked well for me, is that I like to introduce other people,” Paul said. It’s always a great feeling when I’m talking to someone at an event, and I hear about what they’re doing or what they’re wanting to do, and then I can introduce someone else who maybe matches that. “And it’s also good for me, then I can just be kind of passive there,” Paul joked. “I don’t have to be out there myself so much, if they’re talking to each other.” His last piece of advice for introverts is somewhat counterintuitive. “Paradoxically,” he told me, “it helps if you’re in some sort of leadership position.” If you’re an introvert, my advice would be one, just do it, but then also look for opportunities for helping in some more formal capacity, whether it’s organizing an event yourself, volunteering at an event . . . [or] making presentations. “Like for me, when I’ve organized a Tokyo Rubyist Meetup,” Paul said, “[then] naturally as the organizer there people come to talk to me and ask me questions. . . . And it’s been similar when I’ve presented at an event, because then people have something that they know that you know something about, and maybe they want to know more about it, and so then they can ask you more questions and lead the conversation that way.” Offline vs online networking When it comes to offline vs online networking, Paul prefers offline. In-person events are great for networking because they create serendipity. You meet people through events you wouldn’t meet otherwise just because you’re in the same physical space as them. Those time and space constraints add pressure to make conversation—in a good way. “It’s natural when you are meeting someone, you ask about what they’re doing, and you make that small connection there. Then, after seeing them at multiple different events, you get a bit of a stronger connection to them.” “Physical events are [also] much more constrained in the number of people, so it’s easier to help people,” he added. “Like with TokyoDev, I can’t help every single person online there, but if someone meets me at the event [and is] asking for advice or something like that, of course I’ve got to answer them. And I have more time for them there, because we’re in the same place at the same time.” As humans, we’re more likely to help other people we have met in person, I think just because that’s how our brains work. That being said, Paul’s also found success with online networking. For example, several TokyoDev contributors—myself included—started working with Paul after interacting with him online. I commented on TokyoDev’s Dungeons and Dragons article, which led to Paul checking my profile and asking to chat about my experience. Scott, our community moderator and editor, joined TokyoDev in a paid position after being active on the TokyoDev Discord. Michelle was also active on the Discord, and Paul initially asked her to write an article for TokyoDev on being a woman software engineer in Japan, before later bringing her onto the team. Key to these results was that they involved no stereotypical “networking” strategies on either side: we all connected simply by playing a role in a shared, online community. Consistent interactions with others, particularly over a longer period of time, builds mutual trust and understanding. Your online presence can help with offline networking. As TokyoDev became bigger and more people knew about me through my blog, it became a lot easier to network with people at events because they’re like, ‘Hey, you’re Paul from TokyoDev. I like that site.’ “It just leads to more opportunities,” he continued. “If you’ve interacted with someone before online, and then you meet them offline, you already do have a bit of a relationship with them, so you’re more likely to have a place to start the conversation. [And] if you’re someone who is struggling with doing in-person networking, the more you can produce or put out there [online], the more opportunities that can lead to.” Networking in Japanese While there are a number of events throughout Japan that are primarily in English, for best networking results, developers should take advantage of Japanese events as well—even if your Japanese isn’t that good. In 2010, Paul created the Tokyo Rubyist Meetup, with the intention of bringing together Japanese and international developers. To ensure it succeeded, he knew he needed more connections to the Japanese development community. “So I started attending a lot of Japanese developer events where I was the only non-Japanese person there,” said Paul. “I didn’t have such great Japanese skills. I couldn’t understand all the presentations. But it still gave me a chance to make lots of connections, both with people who would later present at [Tokyo Rubyist Meetup], but also with other Japanese developers whom I would work with either on my own products or also on other client projects.” I think it helped being kind of a visible minority. People were curious about me, about why I was attending these events. Their curiosity not only helped him network, but also gave him a helping hand when it came to Japanese conversation. “It’s a lot easier for me in Japanese to be asked questions and answer them,” he admitted. But Paul wasn’t just attending those seminars and events in a passive manner. He soon started delivering presentations himself, usually as part of Lightning Talks—again, despite his relatively low level of Japanese. “It doesn’t matter if you do a bad job of it,” he said. Japanese people I think are really receptive to people trying to speak in Japanese and making an effort. I think they’re happy to have someone who isn’t Japanese present, even if they don’t do a great job. He also quickly learned that the most important networking doesn’t take place at the meetup itself. “At least in the past,” he explained, “it was really split . . . [there’s the] seminar time where everyone goes and watches someone present. Everyone’s pretty passive there and there isn’t much conversation going on between attendees. “Then afterwards—and maybe less than half of the people attend—but they go to a restaurant and have drinks after the event. And that’s where all the real socialization happens, and so that’s where I was able to really make the most connections.” That said, Paul noted that the actual “drinking” part of the process has noticeably diminished. “Drinking culture in Japan is changing a lot,” he told me. “I noticed that even when hosting the Tokyo Rubyist Meetup. When we were first hosting it, we [had] an average of 2.5 beers per participant. And more recently, the average is one or less per participant there. “I think there is not so much of an expectation for people to drink a lot. Young Japanese people don’t drink at the same rate, so don’t feel like you actually have to get drunk at these events. You probably shouldn’t,” he added with a laugh. What you should do is be persistent, and patient. It took Paul about a year of very regularly attending events before he felt he was treated as a member of the community. “Literally I was attending more than the typical Japanese person,” he said. “At the peak, there were a couple events per week.” His hard work paid off, though. “I think one thing about Japanese culture,” he said, “is that it’s really group based.” Initially, as foreigners, we see ourselves in the foreign group versus the Japanese group, and there’s kind of a barrier there. But if you can find some other connection, like in my case Ruby, then with these developers I became part of the “Ruby developer group,” and then I felt much more accepted. Eventually he experienced another benefit. “I think it was after a year of volunteering, maybe two years. . . . RubyKaigi, the biggest Ruby conference in Japan and one of the biggest developer conferences in Japan [in general], used Doorkeeper, the event registration system [I created], to manage their event. “That was a big win for us because it showed that we were a serious system to lots of people there. It exposed us to lots of potential users and was one of the things that I think led to us, for a time, being the most popular event registration system among the tech community in Japan.” Based on his experiences, Paul would urge more developers to try attending Japanese dev events. “Because I think a lot of non-Japanese people are still too intimidated to go to these events, even if they have better Japanese ability than I did. “If you look at most of the Japanese developer events happening now, I think the participants are almost exclusively Japanese, but still, that doesn’t need to be the case.” Takeaways What Paul hopes other developers will take away from this article is that networking shouldn’t feel sleazy. Instead, good networking looks like: Being interested in other people. Asking them questions is the easiest way to start a conversation and make a genuine connection. Occasionally just making yourself go to that in-person event. Serendipity can’t happen if you don’t create opportunities for it. Introducing people to each other—it’s a fast and stress-free way to make more connections. Volunteering for events or organizing your own. Supporting offline events with a solid online presence as well. Not being afraid to attend Japanese events, even if your Japanese isn’t good. Above all, Paul stressed, don’t overcomplicate what networking is at its core. Really what networking comes down to is learning about what other people are doing, and how you can help them or how they can help you. Whether you’re online, offline, or doing it in Japanese, that mindset can turn networking from an awkward, sleazy-feeling experience into something you actually enjoy—even on a rainy Tuesday night.
