How it started Four years ago, we were struggling to hire. Our team was small (~23 employees), and we knew that we needed many more people to execute on our audacious vision. While we had had success hiring in our personal networks, those networks now felt tapped; we needed to get further afield. As is our wont, we got together as a team and brainstormed: how could we get a bigger and broader applicant pool? One of our engineers, Sean, shared some personal experience: that Oxide’s principles and values were very personally important to him — but that when he explained them to people unfamiliar with the company, they were (understandably?) dismissed as corporate claptrap. Sean had found, however, that there was one surefire way to cut through the skepticism: to explain our approach to compensation. Maybe, Sean wondered, we should talk about it publicly? "I could certainly write a blog entry explaining it," I offered. At this suggestion, the team practically lunged with enthusiasm: the reaction was so uniformly positive that I have to assume that everyone was sick of explaining this most idiosyncratic aspect of Oxide to friends and family. So what was the big deal about our compensation? Well, as a I wrote in the resulting piece, Compensation as a Reflection of Values, our compensation is not merely transparent, but uniform. The piece — unsurprisingly, given the evergreen hot topic that is compensation — got a ton of attention. While some of that attention was negative (despite the piece trying to frontrun every HN hater!), much of it was positive — and everyone seemed to be at least intrigued. And in terms of its initial purpose, the piece succeeded beyond our wildest imagination: it brought a surge of new folks interested in the company. Best of all, the people new to Oxide were interested for all of the right reasons: not the compensation per se, but for the values that the compensation represents. The deeper they dug, the more they found to like — and many who learned about Oxide for the first time through that blog entry we now count as long-time, cherished colleagues. That blog entry was a long time ago now, and today we have ~75 employees (and a shipping product!); how is our compensation model working out for us? How it’s going Before we get into our deeper findings, two updates that are so important that we have updated the blog entry itself. First, the dollar figure itself continues to increase over time (as of this writing in 2025, $207,264); things definitely haven’t gotten (and aren’t getting!) any cheaper. And second, we did introduce variable compensation for some sales roles. Yes, those roles can make more than the rest of us — but they can also make less, too. And, importantly: if/when those folks are making more than the rest of us, it’s because they’re selling a lot — a result that can be celebrated by everyone! Those critical updates out of the way, how is it working? There have been a lot of surprises along the way, mostly (all?) of the positive variety. A couple of things that we have learned: People take their own performance really seriously. When some outsiders hear about our compensation model, they insist that it can’t possibly work because "everyone will slack off." I have come to find this concern to be more revealing of the person making the objection than of our model, as our experience has been in fact the opposite: in my one-on-one conversations with team members, a frequent subject of conversation is people who are concerned that they aren’t doing enough (or that they aren’t doing the right thing, or that their work is progressing slower than they would like). I find my job is often to help quiet this inner critic while at the same time stoking what I feel is a healthy urge: when one holds one’s colleagues in high regard, there is an especially strong desire to help contribute — to prove oneself worthy of a superlative team. Our model allows people to focus on their own contribution (whatever it might be). People take hiring really seriously. When evaluating a peer (rather than a subordinate), one naturally has high expectations — and because (in the sense of our wages, anyway) everyone at Oxide is a peer, it shouldn’t be surprising that folks have very high expectations for potential future colleagues. And because the Oxide hiring process is writing intensive, it allows for candidates to be thoroughly reviewed by Oxide employees — who are tough graders! It is, bluntly, really hard to get a job at Oxide. It allows us to internalize the importance of different roles. One of the more incredible (and disturbingly frequent) objections I have heard is: "But is that what you’ll pay support folks?" I continue to find this question offensive, but I no longer find it surprising: the specific dismissal of support roles reveals a widespread and corrosive devaluation of those closest to customers. My rejoinder is simple: think of the best support engineers you’ve worked with; what were they worth? Anyone who has shipped complex systems knows these extraordinary people — calm under fire, deeply technical, brilliantly resourceful, profoundly empathetic — are invaluable to the business. So what if you built a team entirely of folks like that? The response has usually been: well, sure, if you’re going to only hire those folks. Yeah, we are — and we have! It allows for fearless versatility. A bit of a corollary to the above, but subtly different: even though we (certainly!) hire and select for certain roles, our uniform compensation means we can in fact think primarily in terms of people unconfined by those roles. That is, we can be very fluid about what we’re working on, without fear of how it will affect a perceived career trajectory. As a concrete example: we had a large customer that wanted to put in place a program for some of the additional work they wanted to see in the product. The complexity of their needs required dedicated program management resources that we couldn’t spare, and in another more static company we would have perhaps looked to hire. But in our case, two folks came together — CJ from operations, and Izzy from support — and did something together that was in some regards new to both of them (and was neither of their putative full-time jobs!) The result was indisputably successful: the customer loved the results, and two terrific people got a chance to work closely together without worrying about who was dotted-lined to whom. It has allowed us to organizationally scale. Many organizations describe themselves as flat, and a reasonable rebuttal to this are the "shadow hierarchies" created by the tyranny of structurelessness. And indeed, if one were to read (say) Valve’s (in)famous handbook, the autonomy seems great — but the stack ranking decidedly less so, especially because the handbook is conspicuously silent on the subject of compensation. (Unsurprisingly, compensation was weaponized at Valve, which descended into toxic cliquishness.) While we believe that autonomy is important to do one’s best work, we also have a clear structure at Oxide in that Steve Tuck (Oxide co-founder and CEO) is in charge. He has to be: he is held accountable to our investors — and he must have the latitude to make decisions. Under Steve, it is true that we don’t have layers of middle management. Might we need some in the future? Perhaps, but what fraction of middle management in a company is dedicated to — at some level — determining who gets what in terms of compensation? What happens when you eliminate that burden completely? It frees us to both lead and follow. We expect that every Oxide employee has the capacity to lead others — and we tap this capacity frequently. Of course, a company in which everyone is trying to direct all traffic all the time would be a madhouse, so we also very much rely on following one another too! Just as our compensation model allows us to internalize the values of different roles, it allows us to appreciate the value of both leading and following, and empowers us each with the judgement to know when to do which. This isn’t always easy or free of ambiguity, but this particular dimension of our versatility has been essential — and our compensation model serves to encourage it. It causes us to hire carefully and deliberately. Of course, one should always hire carefully and deliberately, but this often isn’t the case — and many a startup has been ruined by reckless expansion of headcount. One of the roots of this can be found in a dirty open secret of Silicon Valley middle management: its ranks are taught to grade their career by the number of reports in their organization. Just as if you were to compensate software engineers based on the number of lines of code they wrote, this results in perverse incentives and predictable disasters — and any Silicon Valley vet will have plenty of horror stories of middle management jockeying for reqs or reorgs when they should have been focusing on product and customers. When you can eliminate middle management, you eliminate this incentive. We grow the team not because of someone’s animal urges to have the largest possible organization, but rather because we are at a point where adding people will allow us to better serve our market and customers. It liberates feedback from compensation. Feedback is, of course, very important: we all want to know when and where we’re doing the right thing! And of course, we want to know too where there is opportunity for improvement. However, Silicon Valley has historically tied feedback so tightly to compensation that it has ceased to even pretend to be constructive: if it needs to be said, performance review processes aren’t, in fact, about improving the performance of the team, but rather quantifying and stack-ranking that performance for purposes of compensation. When compensation is moved aside, there is a kind of liberation for feedback itself: because feedback is now entirely earnest, it can be expressed and received thoughtfully. It allows people to focus on doing the right thing. In a world of traditional, compensation-tied performance review, the organizational priority is around those things that affect compensation — even at the expense of activity that clearly benefits the company. This leads to all sorts of wild phenomena, and most technology workers will be able to tell stories of doing things that were clearly right for the company, but having to hide it from management that thought only narrowly in terms of their own stated KPIs and MBOs. By contrast, over and over (and over!) again, we have found that people do the right thing at Oxide — even if (especially if?) no one is looking. The beneficiary of that right thing? More often than not, it’s our customers, who have uniformly praised the team for going above and beyond. It allows us to focus on the work that matters. Relatedly, when compensation is non-uniform, the process to figure out (and maintain) that non-uniformity is laborious. All of that work — of line workers assembling packets explaining themselves, of managers arming themselves with those packets to fight in the arena of organizational combat, and then of those same packets ultimately being regurgitated back onto something called a review — is work. Assuming such a process is executed perfectly (something which I suppose is possible in the abstract, even though I personally have never seen it), this is work that does not in fact advance the mission of the company. Not having variable compensation gives us all of that time and energy back to do the actual work — the stuff that matters. It has stoked an extraordinary sense of teamwork. For me personally — and as I relayed on an episode of Software Misadventures — the highlights of my career have been being a part of an extraordinary team. The currency of a team is mutual trust, and while uniform compensation certainly isn’t the only way to achieve that trust, boy does it ever help! As Steve and I have told one another more times that we can count: we are so lucky to work on this team, with its extraordinary depth and breadth. While our findings have been very positive, I would still reiterate what we said four years ago: we don’t know what the future holds, and it’s easier to make an unwavering commitment to the transparency rather than the uniformity. That said, the uniformity has had so many positive ramifications that the model feels more important than ever. We are beyond the point of this being a curiosity; it’s been essential for building a mission-focused team taking on a problem larger than ourselves. So it’s not a fit for everyone — but if you are seeking an extraordinary team solving hard problems in service to customers, consider Oxide!
Sometime in late 2007, we had the idea of a DTrace conference. Or really, more of a meetup; from the primordial e-mail I sent: The goal here, by the way, is not a DTrace user group, but more of a face-to-face meeting with people actively involved in DTrace — either by porting it to another system, by integrating probes into higher level environments, by building higher-level tools on top of DTrace or by using it heavily and/or in a critical role. That said, we also don’t want to be exclusionary, so our thinking is that the only true requirement for attending is that everyone must be prepared to speak informally for 15 mins or so on what they are doing with DTrace, any limitations that they have encountered, and some ideas for the future. We’re thinking that this is going to be on the order of 15-30 people (though more would be a good problem to have — we’ll track it if necessary), that it will be one full day (breakfast in the morning through drinks into the evening), and that we’re going to host it here at our offices in San Francisco sometime in March 2008. This same note also included some suggested names for the gathering, including what in hindsight seems a clear winner: DTrace Bi-Mon-Sci-Fi-Con. As if knowing that I should leave an explanatory note to my future self as to why this name was not selected, my past self fortunately clarified: "before everyone clamors for the obvious Bi-Mon-Sci-Fi-Con, you should know that most Millennials don’t (sadly) get the reference." (While I disagree with the judgement of my past self, it at least indicates that at some point I cared if anyone got the reference.) We settled on a much more obscure reference, and had the first dtrace.conf in March 2008. Befitting the style of the time, it was an unconference (a term that may well have hit its apogee in 2008) that you signed up to attend by editing a wiki. More surprising given the year (and thanks entirely to attendee Ben Rockwood), it was recorded — though this is so long ago that I referred to it as video taping (and with none of the participants mic’d, I’m afraid the quality isn’t very good). The conference, however, was terrific, viz. the reports of Adam, Keith and Stephen (all somehow still online nearly two decades later). If anything, it was a little too good: we realized that we couldn’t recreate the magic, and we demurred on making it an annual event. Years passed, and memories faded. By 2012, it felt like we wanted to get folks together again, now under a post-lawnmower corporate aegis in Joyent. The resulting dtrace.conf(12) was a success, and the Olympiad cadence felt like the right one; we did it again four years later at dtrace.conf(16). In 2020, we came back together for a new adventure — and the DTrace Olympiad was not lost on Adam. Alas, dtrace.conf(20) — like the Olympics themselves — was cancelled, if implicitly. Unlike the Olympics, however, it was not to be rescheduled. More years passed and DTrace continued to prove its utility at Oxide; last year when Adam and I did our "DTrace at 20" episode of Oxide and Friends, we vowed to hold dtrace.conf(24) — and a few months ago, we set our date to be December 11th. At first we assumed we would do something similar to our earlier conferences: a one-day participant-run conference, at the Oxide office in Emeryville. But times have changed: thanks to the rise of remote work, technologists are much more dispersed — and many more people would need to travel for dtrace.conf(24) than in previous DTrace Olympiads. Travel hasn’t become any cheaper since 2008, and the cost (and inconvenience) was clearly going to limit attendance. The dilemma for our small meetup highlights the changing dynamics in tech conferences in general: with talks all recorded and made publicly available after the conference, how does one justify attending a conference in person? There can be reasonable answers to that question, of course: it may be the hallway track, or the expo hall, or the after-hours socializing, or perhaps some other special conference experience. But it’s also not surprising that some conferences — especially ones really focused on technical content — have decided that they are better off doing as conference giant O’Reilly Media did, and going exclusively online. And without the need to feed and shelter participants, the logistics for running a conference become much more tenable — and the price point can be lowered to the point that even highly produced conferences like P99 CONF can be made freely available. This, in turn, leads to much greater attendance — and a network effect that can get back some of what one might lose going online. In particular, using chat as the hallway track can be more much effective (and is certainly more scalable!) than the actual physical hallways at a conference. For conferences in general, there is a conversation to be had here (and as a teaser, Adam and I are going to talk about it with Stephen O’Grady and Theo Schlossnagle on Oxide and Friends next week, but for our quirky, one-day, Olympiad-cadence dtrace.conf, the decision was pretty easy: there was much more to be gained than lost by going exclusively on-line. So dtrace.conf(24) is coming up next week, and it’s available to everyone. In terms of platform, we’re going to try to keep that pretty simple: we’re going to use Google Meet for the actual presenters, which we will stream in real-time to YouTube — and we’ll use the Oxide Discord for all chat. We’re hoping you’ll join us on December 11th — and if you want to talk about DTrace or a DTrace-adjacent topic, we’d love for you to present! Keeping to the unconference style, if you would like to present, please indicate your topic in the #session-topics Discord channel so we can get the agenda fleshed out. While we’re excited to be online, there are some historical accoutrements of conferences that we didn’t want to give up. First, we have a tradition of t-shirts with dtrace.conf. Thanks to our designer Ben Leonard, we have a banger of a t-shirt, capturing the spirit of our original dtrace.conf(08) shirt but with an Oxide twist. It’s (obviously) harder to make those free but we have tried to price them reasonably. You can get your t-shirt by adding it to your (free) dtrace.conf ticket. (And for those who present at dtrace.conf, your shirt is on us — we’ll send you a coupon code!) Second, for those who can make their way to the East Bay and want some hangout time, we are going to have an après conference social event at the Oxide office starting at 5p. We’re charging something nominal for that too (and like the t-shirt, you pay for that via your dtrace.conf ticket); we’ll have some food and drinks and an Oxide hardware tour for the curious — and (of course?) there will be Fishpong. Much has changed since I sent that e-mail 17 years ago — but the shared values and disposition that brought together our small community continue to endure; we look forward to seeing everyone (virtually) at dtrace.conf(24)!
Oxide Computer Company and Lawrence Livermore National Laboratory Work Together to Advance Cloud and HPC Convergence Oxide Computer Company and Lawrence Livermore National Laboratory (LLNL) today announced a plan to bring on-premises cloud computing capabilities to the Livermore Computing (LC) high-performance computing (HPC) center. The rack-scale Oxide Cloud Computer allows LLNL to improve the efficiency of operational workloads and will provide users in the National Nuclear Security Administration (NNSA) with new capabilities for provisioning secure, virtualized services alongside HPC workloads. HPC centers have traditionally run batch workloads for large-scale scientific simulations and other compute-heavy applications. HPC workloads do not exist in isolation—there are a multitude of persistent, operational services that keep the HPC center running. Meanwhile, HPC users also want to deploy cloud-like persistent services—databases, Jupyter notebooks, orchestration tools, Kubernetes clusters. Clouds have developed extensive APIs, security layers, and automation to enable these capabilities, but few options exist to deploy fully virtualized, automated cloud environments on-premises. The Oxide Cloud Computer allows organizations to deliver secure cloud computing capabilities within an on-premises environment. On-premises environments are the next frontier for cloud computing. LLNL is tackling some of the hardest and most important problems in science and technology, requiring advanced hardware, software, and cloud capabilities. We are thrilled to be working with their exceptional team to help advance those efforts, delivering an integrated system that meets their rigorous requirements for performance, efficiency, and security. — Steve TuckCEO at Oxide Computer Company Leveraging the new Oxide Cloud Computer, LLNL will enable staff to provision virtual machines (VMs) and services via self-service APIs, improving operations and modernizing aspects of system management. In addition, LLNL will use the Oxide rack as a proving ground for secure multi-tenancy and for smooth integration with the LLNL-developed Flux resource manager. LLNL plans to bring its users cloud-like Infrastructure-as-a-Service (IaaS) capabilities that work seamlessly with their HPC jobs, while maintaining security and isolation from other users. Beyond LLNL personnel, researchers at the Los Alamos National Laboratory and Sandia National Laboratories will also partner in many of the activities on the Oxide Cloud Computer. We look forward to working with Oxide to integrate this machine within our HPC center. Oxide’s Cloud Computer will allow us to securely support new types of workloads for users, and it will be a proving ground for introducing cloud-like features to operational processes and user workflows. We expect Oxide’s open-source software stack and their transparent and open approach to development to help us work closely together. — Todd GamblinDistinguished Member of Technical Staff at LLNL Sandia is excited to explore the Oxide platform as we work to integrate on-premise cloud technologies into our HPC environment. This advancement has the potential to enable new classes of interactive and on-demand modeling and simulation capabilities. — Kevin PedrettiDistinguished Member of Technical Staff at Sandia National Laboratories LLNL plans to work with Oxide on additional capabilities, including the deployment of additional Cloud Computers in its environment. Of particular interest are scale-out capabilities and disaster recovery. The latest installation underscores Oxide Computer’s momentum in the federal technology ecosystem, providing reliable, state-of-the-art Cloud Computers to support critical IT infrastructure.

We are heartbroken to relay that Charles Beeler, a friend and early investor in Oxide, passed away in September after a battle with cancer. We lost Charles far too soon; he had a tremendous influence on the careers of us both. Our relationship with Charles dates back nearly two decades, to his involvement with the ACM Queue board where he met Bryan. It was unprecedented to have a venture capitalist serve in this capacity with ACM, and Charles brought an entirely different perspective on the practitioner content. A computer science pioneer who also served on the board took Bryan aside at one point: "Charles is one of the good ones, you know." When Bryan joined Joyent a few years later, Charles also got to know Steve well. Seeing the promise in both node.js and cloud computing, Charles became an investor in the company. When companies hit challenging times, some investors will hide — but Charles was the kind of investor to figure out how to fix what was broken. When Joyent needed a change in executive leadership, it was Charles who not only had the tough conversations, but led the search for the leader the company needed, ultimately positioning the company for success. Aside from his investment in Joyent, Charles was an outspoken proponent of node.js, becoming an organizer of the Node Summit conference. In 2017, he asked Bryan to deliver the conference’s keynote, but by then, the relationship between Joyent and node.js had become… complicated, and Bryan felt that it probably wouldn’t be a good idea. Any rational person would have dropped it, but Charles persisted, with characteristic zeal: if the Joyent relationship with node.js had become strained, so much more the reason to speak candidly about it! Charles prevailed, and the resulting talk, Platform as Reflection of Values, became one of Bryan’s most personally meaningful talks. Charles’s persistence was emblematic: he worked behind the scenes to encourage people to do their best work, always with an enthusiasm for the innovators and the creators. As we were contemplating Oxide, we told Charles what we wanted to do long before we had a company. Charles laughed with delight: "I hoped that you two would do something big, and I am just so happy for you that you’re doing something so ambitious!" As we raised seed capital, we knew that we were likely a poor fit for Charles and his fund. But we also knew that we deeply appreciated his wisdom and enthusiasm; we couldn’t resist pitching him on Oxide. Charles approached the investment in Oxide as he did with so many other aspects: with curiosity, diligence, empathy, and candor. He was direct with us that despite his enthusiasm for us personally, Oxide would be a challenging investment for his firm. But he also worked with us to address specific objections, and ultimately he won over his partnership. We were thrilled when he not only invested, but pulled together a syndicate of like-minded technologists and entrepreneurs to join him. Ever since, he has been a huge Oxide fan. Befitting his enthusiasm, one of his final posts expressed his enthusiasm and pride in what the Oxide team has built. Charles, thank you. You told us you were proud of us — and it meant the world. We are gutted to no longer have you with us; your influence lives on not just in Oxide, but also in the many people that you have inspired. You were the best of venture capital. Closer to the heart, you were a terrific friend to us both; thank you.

What does it mean when someone writes that a programming language is “strongly typed”? I’ve known for many years that “strongly typed” is a poorly-defined term. Recently I was prompted on Lobsters to explain why it’s hard to understand what someone means when they use the phrase. I came up with more than five meanings! how strong? The various meanings of “strongly typed” are not clearly yes-or-no. Some developers like to argue that these kinds of integrity checks must be completely perfect or else they are entirely worthless. Charitably (it took me a while to think of a polite way to phrase this), that betrays a lack of engineering maturity. Software engineers, like any engineers, have to create working systems from imperfect materials. To do so, we must understand what guarantees we can rely on, where our mistakes can be caught early, where we need to establish processes to catch mistakes, how we can control the consequences of our mistakes, and how to remediate when somethng breaks because of a mistake that wasn’t caught. strong how? So, what are the ways that a programming language can be strongly or weakly typed? In what ways are real programming languages “mid”? Statically typed as opposed to dynamically typed? Many languages have a mixture of the two, such as run time polymorphism in OO languages (e.g. Java), or gradual type systems for dynamic languages (e.g. TypeScript). Sound static type system? It’s common for static type systems to be deliberately unsound, such as covariant subtyping in arrays or functions (Java, again). Gradual type systems migh have gaping holes for usability reasons (TypeScript, again). And some type systems might be unsound due to bugs. (There are a few of these in Rust.) Unsoundness isn’t a disaster, if a programmer won’t cause it without being aware of the risk. For example: in Lean you can write “sorry” as a kind of “to do” annotation that deliberately breaks soundness; and Idris 2 has type-in-type so it accepts Girard’s paradox. Type safe at run time? Most languages have facilities for deliberately bypassing type safety, with an “unsafe” library module or “unsafe” language features, or things that are harder to spot. It can be more or less difficult to break type safety in ways that the programmer or language designer did not intend. JavaScript and Lua are very safe, treating type safety failures as security vulnerabilities. Java and Rust have controlled unsafety. In C everything is unsafe. Fewer weird implicit coercions? There isn’t a total order here: for instance, C has implicit bool/int coercions, Rust does not; Rust has implicit deref, C does not. There’s a huge range in how much coercions are a convenience or a source of bugs. For example, the PHP and JavaScript == operators are made entirely of WAT, but at least you can use === instead. How fancy is the type system? To what degree can you model properties of your program as types? Is it convenient to parse, not validate? Is the Curry-Howard correspondance something you can put into practice? Or is it only capable of describing the physical layout of data? There are probably other meanings, e.g. I have seen “strongly typed” used to mean that runtime representations are abstract (you can’t see the underlying bytes); or in the past it sometimes meant a language with a heavy type annotation burden (as a mischaracterization of static type checking). how to type So, when you write (with your keyboard) the phrase “strongly typed”, delete it, and come up with a more precise description of what you really mean. The desiderata above are partly overlapping, sometimes partly orthogonal. Some of them you might care about, some of them not. But please try to communicate where you draw the line and how fuzzy your line is.
(Last week's newsletter took too long and I'm way behind on Logic for Programmers revisions so short one this time.1) In classical logic, two operators F/G are duals if F(x) = !G(!x). Three examples: x || y is the same as !(!x && !y). <>P ("P is possibly true") is the same as ![]!P ("not P isn't definitely true"). some x in set: P(x) is the same as !(all x in set: !P(x)). (1) is just a version of De Morgan's Law, which we regularly use to simplify boolean expressions. (2) is important in modal logic but has niche applications in software engineering, mostly in how it powers various formal methods.2 The real interesting one is (3), the "quantifier duals". We use lots of software tools to either find a value satisfying P or check that all values satisfy P. And by duality, any tool that does one can do the other, by seeing if it fails to find/check !P. Some examples in the wild: Z3 is used to solve mathematical constraints, like "find x, where f(x) >= 0. If I want to prove a property like "f is always positive", I ask z3 to solve "find x, where !(f(x) >= 0), and see if that is unsatisfiable. This use case powers a LOT of theorem provers and formal verification tooling. Property testing checks that all inputs to a code block satisfy a property. I've used it to generate complex inputs with certain properties by checking that all inputs don't satisfy the property and reading out the test failure. Model checkers check that all behaviors of a specification satisfy a property, so we can find a behavior that reaches a goal state G by checking that all states are !G. Here's TLA+ solving a puzzle this way.3 Planners find behaviors that reach a goal state, so we can check if all behaviors satisfy a property P by asking it to reach goal state !P. The problem "find the shortest traveling salesman route" can be broken into some route: distance(route) = n and all route: !(distance(route) < n). Then a route finder can find the first, and then convert the second into a some and fail to find it, proving n is optimal. Even cooler to me is when a tool does both finding and checking, but gives them different "meanings". In SQL, some x: P(x) is true if we can query for P(x) and get a nonempty response, while all x: P(x) is true if all records satisfy the P(x) constraint. Most SQL databases allow for complex queries but not complex constraints! You got UNIQUE, NOT NULL, REFERENCES, which are fixed predicates, and CHECK, which is one-record only.4 Oh, and you got database triggers, which can run arbitrary queries and throw exceptions. So if you really need to enforce a complex constraint P(x, y, z), you put in a database trigger that queries some x, y, z: !P(x, y, z) and throws an exception if it finds any results. That all works because of quantifier duality! See here for an example of this in practice. Duals more broadly "Dual" doesn't have a strict meaning in math, it's more of a vibe thing where all of the "duals" are kinda similar in meaning but don't strictly follow all of the same rules. Usually things X and Y are duals if there is some transform F where X = F(Y) and Y = F(X), but not always. Maybe the category theorists have a formal definition that covers all of the different uses. Usually duals switch properties of things, too: an example showing some x: P(x) becomes a counterexample of all x: !P(x). Under this definition, I think the dual of a list l could be reverse(l). The first element of l becomes the last element of reverse(l), the last becomes the first, etc. A more interesting case is the dual of a K -> set(V) map is the V -> set(K) map. IE the dual of lived_in_city = {alice: {paris}, bob: {detroit}, charlie: {detroit, paris}} is city_lived_in_by = {paris: {alice, charlie}, detroit: {bob, charlie}}. This preserves the property that x in map[y] <=> y in dual[x]. And after writing this I just realized this is partial retread of a newsletter I wrote a couple months ago. But only a partial retread! ↩ Specifically "linear temporal logics" are modal logics, so "eventually P ("P is true in at least one state of each behavior") is the same as saying !always !P ("not P isn't true in all states of all behaviors"). This is the basis of liveness checking. ↩ I don't know for sure, but my best guess is that Antithesis does something similar when their fuzzer beats videogames. They're doing fuzzing, not model checking, but they have the same purpose check that complex state spaces don't have bugs. Making the bug "we can't reach the end screen" can make a fuzzer output a complete end-to-end run of the game. Obvs a lot more complicated than that but that's the general idea at least. ↩ For CHECK to constraint multiple records you would need to use a subquery. Core SQL does not support subqueries in check. It is an optional database "feature outside of core SQL" (F671), which Postgres does not support. ↩
Omarchy 2.0 was released on Linux's 34th birthday as a gift to perhaps the greatest open-source project the world has ever known. Not only does Linux run 95% of all servers on the web, billions of devices as an embedded OS, but it also turns out to be an incredible desktop environment! It's crazy that it took me more than thirty years to realize this, but while I spent time in Apple's walled garden, the free software alternative simply grew better, stronger, and faster. The Linux of 2025 is not the Linux of the 90s or the 00s or even the 10s. It's shockingly more polished, capable, and beautiful. It's been an absolute honor to celebrate Linux with the making of Omarchy, the new Linux distribution that I've spent the last few months building on top of Arch and Hyprland. What began as a post-install script has turned into a full-blown ISO, dedicated package repository, and flourishing community of thousands of enthusiasts all collaborating on making it better. It's been improving rapidly with over twenty releases since the premiere in late June, but this Version 2.0 update is the biggest one yet. If you've been curious about giving Linux a try, you're not afraid of an operating system that asks you to level up and learn a little, and you want to see what a totally different computing experience can look and feel like, I invite you to give it a go. Here's a full tour of Omarchy 2.0.
In 2020, Apple released the M1 with a custom GPU. We got to work reverse-engineering the hardware and porting Linux. Today, you can run Linux on a range of M1 and M2 Macs, with almost all hardware working: wireless, audio, and full graphics acceleration. Our story begins in December 2020, when Hector Martin kicked off Asahi Linux. I was working for Collabora working on Panfrost, the open source Mesa3D driver for Arm Mali GPUs. Hector put out a public call for guidance from upstream open source maintainers, and I bit. I just intended to give some quick pointers. Instead, I bought myself a Christmas present and got to work. In between my university coursework and Collabora work, I poked at the shader instruction set. One thing led to another. Within a few weeks, I drew a triangle. In 3D graphics, once you can draw a triangle, you can do anything. Pretty soon, I started work on a shader compiler. After my final exams that semester, I took a few days off from Collabora to bring up an OpenGL driver capable of spinning gears with my new compiler. Over the next year, I kept reverse-engineering and improving the driver until it could run 3D games on macOS. Meanwhile, Asahi Lina wrote a kernel driver for the Apple GPU. My userspace OpenGL driver ran on macOS, leaving her kernel driver as the missing piece for an open source graphics stack. In December 2022, we shipped graphics acceleration in Asahi Linux. In January 2023, I started my final semester in my Computer Science program at the University of Toronto. For years I juggled my courses with my part-time job and my hobby driver. I faced the same question as my peers: what will I do after graduation? Maybe Panfrost? I started reverse-engineering of the Mali Midgard GPU back in 2017, when I was still in high school. That led to an internship at Collabora in 2019 once I graduated, turning into my job throughout four years of university. During that time, Panfrost grew from a kid’s pet project based on blackbox reverse-engineering, to a professional driver engineered by a team with Arm’s backing and hardware documentation. I did what I set out to do, and the project succeeded beyond my dreams. It was time to move on. What did I want to do next? Finish what I started with the M1. Ship a great driver. Bring full, conformant OpenGL drivers to the M1. Apple’s drivers are not conformant, but we should strive for the industry standard. Bring full, conformant Vulkan to Apple platforms, disproving the myth that Vulkan isn’t suitable for Apple hardware. Bring Proton gaming to Asahi Linux. Thanks to Valve’s work for the Steam Deck, Windows games can run better on Linux than even on Windows. Why not reap those benefits on the M1? Panfrost was my challenge until we “won”. My next challenge? Gaming on Linux on M1. Once I finished my coursework, I started full-time on gaming on Linux. Within a month, we shipped OpenGL 3.1 on Asahi Linux. A few weeks later, we passed official conformance for OpenGL ES 3.1. That put us at feature parity with Panfrost. I wanted to go further. OpenGL (ES) 3.2 requires geometry shaders, a legacy feature not supported by either Arm or Apple hardware. The proprietary OpenGL drivers emulate geometry shaders with compute, but there was no open source prior art to borrow. Even though multiple Mesa drivers need geometry/tessellation emulation, nobody did the work to get there. My early progress on OpenGL was fast thanks to the mature common code in Mesa. It was time to pay it forward. Over the rest of the year, I implemented geometry/tessellation shader emulation. And also the rest of the owl. In January 2024, I passed conformance for the full OpenGL 4.6 specification, finishing up OpenGL. Vulkan wasn’t too bad, either. I polished the OpenGL driver for a few months, but once I started typing a Vulkan driver, I passed 1.3 conformance in a few weeks. What remained was wiring up the geometry/tessellation emulation to my shiny new Vulkan driver, since those are required for Direct3D. Et voilà, Proton games. Along the way, Karol Herbst passed OpenCL 3.0 conformance on the M1, running my compiler atop his “rusticl” frontend. Meanwhile, when the Vulkan 1.4 specification was published, we were ready and shipped a conformant implementation on the same day. After that, I implemented sparse texture support, unlocking Direct3D 12 via Proton. …Now what? Ship a great driver? Check. Conformant OpenGL 4.6, OpenGL ES 3.2, and OpenCL 3.0? Check. Conformant Vulkan 1.4? Check. Proton gaming? Check. That’s a wrap. We’ve succeeded beyond my dreams. The challenges I chased, I have tackled. The drivers are fully upstream in Mesa. Performance isn’t too bad. With the Vulkan on Apple myth busted, conformant Vulkan is now coming to macOS via LunarG’s KosmicKrisp project building on my work. Satisfied, I am now stepping away from the Apple ecosystem. My friends in the Asahi Linux orbit will carry the torch from here. As for me? Onto the next challenge!
TokyoDev has published a number of different guides on coming to Japan to work as a software developer. But what if you’re already employed in another industry in Japan, and are considering changing your career to software development? I interviewed four people who became developers after they moved to Japan, for their advice and personal experiences on: Why they chose development How they switched careers How they successfully found their first jobs What mistakes they made in the job hunt The most important advice they give to others Why switch to software development? A lifelong goal For Yuta Asakura, a career in software was the dream all along. “I’ve always wanted to work with computers,” he said, “but due to financial difficulties, I couldn’t pursue a degree in computer science. I had to start working early to support my single mother. As the eldest child, I focused on helping my younger brother complete his education.” To support his family, Asakura worked in construction for eight years, eventually becoming a foreman in Yokohama. Meanwhile, his brother graduated, and became a software engineer after joining the Le Wagon Tokyo bootcamp. About a year before his brother graduated, Asakura began to delve back into development. “I had already begun self-studying in my free time by taking online courses and building small projects,” he explained. “ I quickly became hooked by how fun and empowering it was to learn, apply, and build. It wasn’t always easy. There were moments I wanted to give up, but the more I learned, the more interesting things I could create. That feeling kept me going.” What truly inspired me was the idea of creating something from nothing. Coming from a construction background, I was used to building things physically. But I wanted to create things that were digital, scalable, borderless, and meaningful to others. An unexpected passion As Andrew Wilson put it, “Wee little Andrew had a very digital childhood,” full of games and computer time. Rather than pursuing tech, however, he majored in Japanese and moved to Japan in 2012, where he initially worked as a language teacher and recruiter before settling into sales. Wilson soon discovered that sales wasn’t really his strong suit. “At the time I was selling three different enterprise software solutions.” So I had to have a fairly deep understanding of that software from a user perspective, and in the course of learning about these products and giving technical demonstrations, I realized that I liked doing that bit of my job way more than I liked actually trying to sell these things. Around that time, he also realized he didn’t want to manually digitize the many business cards he always collected during sales meetings: “That’s boring, and I’m lazy.” So instead, he found a business card-scanning app, made a spreadsheet to contain the data, automated the whole process, and shared it internally within his company. His manager approached him soon afterwards, saying, “You built this? We were looking to hire someone to do this!” Encouraged, Wilson continued to develop it. “As soon as I was done with work,” he explained with a laugh, “I was like, ‘Oh boy, I can work on my spreadsheet!’” As a result, Wilson came to the conclusion that he really should switch careers and pursue his passion for programming. Similarly to Wilson, Malcolm Hendricks initially focused on Japanese. He came to Japan as an exchange student in 2002, and traveled to Japan several more times before finally relocating in 2011. Though his original role was as a language teacher, he soon found a job at a Japanese publishing company, where he worked as an editor and writer for seven years. However, he felt burned out on the work, and also that he was in danger of stagnating; since he isn’t Japanese, the road to promotion was a difficult one. He started following some YouTube tutorials on web development, and eventually began creating websites for his friends. Along the way, he fell in love with development, on both a practical and a philosophical level. “There’s another saying I’ve heard here and there—I don’t know exactly who to attribute it to—but the essence of it goes that ‘Computer science is just teaching rocks how to think,’” Hendricks said. “My mentor Bob has been guiding me through the very fundamentals of computer science, down to binary calculations, Boolean logic, gate theory, and von Neumann architecture. He explains the fine minutia and often concludes with, ‘That’s how it works. There’s no magic to it.’ “Meanwhile, in the back of my mind, I can’t help but be mystified at the things we are all now able to do, such as having video calls from completely different parts of the world, or even me here typing on squares of plastic to make letters appear on a screen that has its own source of light inside it. . . . [It] sounds like the highest of high-fantasy wizardry to me.” I’ve always had a love for technomancy, but I never figured I might one day get the chance to be a technomancer myself. And I love it! We have the ability to create nigh unto anything in the digital world. A practical solution When Paulo D’Alberti moved to Japan in 2019, he only spoke a little Japanese, which limited his employment prospects. With his prior business experience, he landed an online marketing role for a blockchain startup, but eventually exited the company to pursue a more stable work environment. “But when I decided to leave the company,” D’Alberti said, “my Japanese was still not good enough to do business. So I was at a crossroads.” Do I decide to join a full-time Japanese language course, aiming to get JLPT N2 or the equivalent, and find a job on the business side? . . . Or do I say screw it and go for a complete career change and get skills in something more technical, that would allow me to carry those skills [with me] even if I were to move again to another country?” The portability of a career in development was a major plus for D’Alberti. “That was one of the big reasons. Another consideration was that, looking at the boot camps that were available, the promise was ‘Yeah, we’ll teach you to be a software developer in nine weeks or two months.’ That was a much shorter lead time than getting from JLPT N4 to N2. I definitely wouldn’t be able to do that in two months.” Since D’Alberti had family obligations, the timeline for his career switch was crucial. “We still had family costs and rent and groceries and all of that. I needed to find a job as soon as possible. I actually already at that point had been unsuccessfully job hunting for two months. So that was like, ‘Okay, the savings are winding up, and we are running out of options. I need to make a decision and make it fast.’” How to switch careers Method 1: Software Development Bootcamp Under pressure to find new employment quickly, D’Alberti decided to enter the Le Wagon Coding Bootcamp in Tokyo. Originally, he wavered between Le Wagon and Code Chrysalis, which has since ended its bootcamp programs. “I went with Le Wagon for two reasons,” he explained. “There were some scheduling reasons. . . . But the main reason was that Code Chrysalis required you to pass a coding exam before being admitted to their bootcamp.” Since D’Alberti was struggling to learn development by himself, he knew his chances of passing any coding exam were slim. “I tried Code Academy, I tried Solo Learn, I tried a whole bunch of apps online, I would follow the examples, the exercises . . . nothing clicked. I wouldn’t understand what I was doing or why I was doing it.” At the time, Le Wagon only offered full-time web development courses, although they now also have part-time courses and a data science curriculum. Since D’Alberti was unemployed, a full-time program wasn’t a problem for him, “But it did mean that the people who were present were very particular [kinds] of people: students who could take some time off to add this to their [coursework], or foreigners who took three months off and were traveling and decide to come here and do studying plus sightseeing, and I think there were one or two who actually asked for time off from the job in order to participate.” It was a very intense course, and the experience itself gave me exactly what I needed. I had been trying to learn by myself. It did not work. I did not understand. [After joining], the first day or second day, suddenly everything clicked. D’Alberti appreciated how Le Wagon organized the curriculum to build continuously off previous lessons. By the time he graduated in June of 2019, he’d built three applications from scratch, and felt far more confident in his coding abilities. “It was great. [The curriculum] was amazing, and I really felt super confident in my abilities after the three months. Which, looking back,” he joked, “I still had a lot to learn.” D’Alberti did have some specific advice for those considering a bootcamp: “Especially in the last couple of weeks, it can get very dramatic. You are divided into teams and as a team, you’re supposed to develop an application that you will be demonstrating in front of other people.” Some of the students, D’Alberti explained, felt that pressure intensely; one of his classmates broke down in tears. “Of course,” he added, “one of the big difficulties of joining a bootcamp is economical. The bootcamp itself is quite expensive.” While between 700,000 and 800,000 yen when D’Alberti went through the bootcamp, Le Wagon’s tuition has now risen to 890,000 yen for Web Development and 950,000 for Data Science. At the time D’Alberti joined there was no financial assistance. Now, Le Wagon has an agreement with Hello Work, so that students who are enrolled in the Hello Work system can be reimbursed for up to 70 percent of the bootcamp’s tuition. Though already studying development by himself, Asakura also enrolled in Le Wagon Tokyo in 2024, “to gain structure and accountability,” he said. One lesson that really stayed with me came from Sylvain Pierre, our bootcamp director. He said, ‘You stop being a developer the moment you stop learning or coding.’ That mindset helped me stay on track. Method 2: Online computer science degree Wilson considered going the bootcamp route, but decided against it. He knew, from his experience in recruiting, that a degree would give him an edge—especially in Japan, where having the right degree can make a difference in visa eligibility “The quality of bootcamps is perfectly fine,” he explained. “If you go through a bootcamp and study hard, you can get a job and become a developer no problem. I wanted to differentiate myself on paper as much as I could . . . [because] there are a lot of smart, motivated people who go through a bootcamp.” Whether it’s true or not, whether it’s valid or not, if you take two candidates who are very similar on paper, and one has a coding bootcamp and one has a degree, from a typical Japanese HR perspective, they’re going to lean toward the person with the degree. “Whether that’s good or not, that’s sort of a separate situation,” Wilson added. “But the reality [is] I’m older and I’m trying to make a career change, so I want to make sure that I’m giving myself every advantage that I can.” For these reasons, Wilson opted to get his computer science degree online. “There’s a program out of the University of Oregon, for people who already had a Bachelor’s degree in a different subject to get a Bachelor’s degree in Computer Science. “Because it’s limited to people who already have a Bachelor’s degree, that means you don’t need to take any non-computer science classes. You don’t need any electives or prerequisites or anything like that.” As it happened, Wilson was on paternity leave when he started studying for his degree. “That was one of my motivations to finish quickly!” he said. In the end, with his employer’s cooperation, he extended his paternity leave to two years, and finished the degree in five quarters. Method 3: Self-taught Hendricks took a different route, combining online learning materials with direct experience. He primarily used YouTube tutorials, like this project from one of his favorite channels, to teach himself. Once he had the basics down, he started creating websites for friends, as well as for the publishing company he worked for at the time. With every site, he’d put his name at the bottom of the page, as a form of marketing. This worked well enough that Hendricks was able to quit his work at the translation company and transition to full-time freelancing. However, eventually the freelancing work dried up, and he decided he wanted to experience working at a tech company—and not just for job security reasons. Hendricks saw finding a full-time development role as the perfect opportunity to push himself and see just how far he could get in his new career. There’s a common trope, probably belonging more to the sports world at large, about the importance of shedding ‘blood, sweat, and tears’ in the pursuit of one’s passion . . . and that’s also how I wanted to cut my teeth in the software engineering world. The job hunt While all four are now successfully employed as developers, Asakura, D’Alberti, Wilson, and Hendricks approached and experienced the job hunt differently. Following is their hard-earned advice on best practices and common mistakes. DO network When Hendricks started his job hunt, he faced the disadvantages of not having any formal experience, and also being both physically and socially isolated from other developers. Since he and his family were living in Nagano, he wasn’t able to participate in most of the tech events and meet-ups available in Tokyo or other big cities. His initial job hunt took around a year, and at one point he was sending so many applications that he received a hundred rejections in a week. It wasn’t until he started connecting with the community that he was able to turn it around, eventually getting three good job offers in a single week. Networking, for me, is what made all the difference. It was through networking that I found my mentors, found community, and joined and even started a few great Discord servers. These all undeniably contributed to me ultimately landing my current job, but they also made me feel welcome in the industry. Hendricks particularly credits his mentors, Ean More and Bob Cousins, for giving him great advice. “My initial mentor [Ean More] I actually met through a mutual IT networking Facebook group. I noticed that he was one of the more active members, and that he was always ready to lend a hand to help others with their questions and spread a deeper understanding of programming and computer science. He also often posted snippets of his own code to share with the community and receive feedback, and I was interested in a lot of what he was posting. “I reached out to him and told him I thought it was amazing how selfless he was in the group, and that, while I’m still a junior, if there was ever any grunt work I could do under his guidance, I would be happy to do so. Since he had a history of mentoring others, he offered to do so for me, and we’ve been mentor/mentee and friends ever since.” “My other mentor [Bob Cousins],” Hendricks continued, “was a friend of my late uncle’s. My uncle had originally begun mentoring me shortly before his passing. We were connected through a mutual friend whom I lamented to about not having any clue how to continue following the path my uncle had originally laid before me. He mentioned that he knew just the right person and gave me an email address to contact. I sent an email to the address and was greeted warmly by the man who would become another mentor, and like an uncle to me.” Although Hendricks found him via a personal connection, Cousins runs a mentorship program that caters to a wide variety of industries. Wilson also believes in the power of networking—and not just for the job hunt. “One of the things I like about programming,” he said, “is that it’s a very collaborative community. Everybody wants to help everybody.” We remember that everyone had to start somewhere, and we’ll take time to help those starting out. It’s a very welcoming community. Just do it! We’re all here for you, and if you need help I’ll refer you. Asakura, by contrast, thinks that networking can help, but that it works a little differently in Japan than in other countries. “Don’t rely on it too much,” he said. “Unlike in Western countries, personal referrals don’t always lead directly to job opportunities in Japan. Your skills, effort, and consistency will matter more in the long run.” DO treat the job hunt like a job Once he’d graduated from Le Wagon, D’Alberti said, “I considered job-hunting my full-time job.” I checked all the possible networking events and meetup events that were going on in the city, and tried to attend all of them, every single day. I had a list of 10 different job boards that I would go and just refresh on a daily basis to see, ‘Okay, Is there anything new now?’ And, of course, I talked with recruiters. D’Alberti suggests beginning the search earlier than you think you need to. “I had started actively job hunting even before graduating [from Le Wagon],” he said. “That’s advice I give to everyone who joins the bootcamp. “Two weeks before graduation, you have one simple web application that you can show. You have a second one you’re working on in a team, and you have a third one that you know what it’s going to be about. So, already, there are three applications that you can showcase or you can use to explain your skills. I started going to meetups and to different events, talking with people, showing my CV.” The process wasn’t easy, as most companies and recruiters weren’t interested in hiring for junior roles. But his intensive strategy paid off within a month, as D’Albert landed three invitations to interview: one from a Japanese job board, one from a recruiter, and one from LinkedIn. For Asakura, treating job hunting like a job was as much for his mental health as for his career. “The biggest challenge was dealing with impostor syndrome and feeling like I didn’t belong because I didn’t have a computer science degree,” he explained. “I also experienced burnout from pushing myself too hard.” To cope, I stuck to a structured routine. I went to the gym daily to decompress, kept a consistent study schedule as if I were working full-time, and continued applying for jobs even when it felt hopeless. At first, Asakura tried to apply to jobs strategically by tracking each application, tailoring his resume, and researching every role. “But after dozens of rejections,” he said, “I eventually switched to applying more broadly and sent out over one hundred applications. I also reached out to friends who were already software engineers and asked for direct referrals, but unfortunately, nothing worked out.” Still, Asakura didn’t give up. He practiced interviews in both English and Japanese with his friends, and stayed in touch with recruiters. Most importantly, he kept developing and adding to his portfolio. DO make use of online resources “What ultimately helped me was staying active and visible,” Asakura said. I consistently updated my GitHub, LInkedIn, and Wantedly profiles. Eventually, I received a message on Wantedly from the CTO of a company who was impressed with my portfolio, and that led to my first developer job.” “If you have the time, certifications can also help validate your knowledge,” Asakura added, “especially in fields like cloud and AI. Some people may not realize this, but the rise of artificial intelligence is closely tied to the growth of cloud computing. Earning certifications such as AWS, Kubernetes, and others can give you a strong foundation and open new opportunities, especially as these technologies continue to evolve.” Hendricks also heavily utilized LinkedIn and similar sites, though in a slightly different way. “I would also emphasize the importance of knowing how to use job-hunting sites like Indeed and LinkedIn,” he said. “I had the best luck when I used them primarily to do initial research into companies, then applied directly through the companies’ own websites, rather than through job postings that filter applicants before their resumés ever make it to the actual people looking to hire.” In addition, Hendricks recommends studying coding interview prep tutorials from freeCodeCamp. Along with advice from his mentors and the online communities he joined, he credits those tutorials with helping him successfully receive offers after a long job hunt. DO highlight experience with Japanese culture and language Asakura felt that his experience in Japan, and knowledge of Japanese, gave him an edge. “I understand Japanese work culture [and] can speak the language,” Asakura said, “and as a Japanese national I didn’t require visa sponsorship. That made me a lower-risk hire for companies here.” Hendricks also felt that his excellent Japanese made him a more attractive hire. While applying, he emphasized to companies that he could be a bridge to the global market and business overseas. However, he also admitted this strategy steered him towards applying with more domestic Japanese companies, which were also less likely to hire someone without a computer science degree. “So,” he said, “it sort of washed out.” Wilson is another who put a lot of emphasis on his Japanese language skills, from a slightly different angle. A lot of interviewees typically don’t speak Japanese well . . . and a lot of companies here say that they’re very international, but if they want very good programmers, [those people] spend their lives programming, not studying English. So having somebody who can bridge the language gap on the IT side can be helpful. DO lean into your other experience Several career switchers discovered that their past experiences and skills, while not immediately relevant to their new career, still proved quite helpful in landing that first role—sometimes in very unexpected ways. When Wilson was pitching his language skills to companies, he wasn’t talking about just Japanese–English translation. He also highlighted his prior experience in sales to suggest that he could help communicate with and educate non-technical audiences. “Actually to be a software engineer, there’s a lot of technical communication you have to do.” I have worked with some incredible coders who are so good at the technical side and just don’t want to do the personal side. But for those of us who are not super-geniuses and can’t rely purely on our tech skills . . . there’s a lot of non-technical discussion that goes around building a product.” This strategy, while eventually fruitful, didn’t earn Wilson a job right away. Initially, he applied to more than sixty companies over the course of three to four months. “I didn’t have any professional [coding] experience, so it was actually quite a rough time,” he said. “I interviewed all over the place. I was getting rejected all over town.” The good news was, Wilson said, “I’m from Chicago. I don’t know what it is, but there are a lot of Chicagoans who work in Tokyo for whatever reason.” When he finally landed an interview, one of the three founders of the company was also from Chicago, giving them something in common. “We hit it off really well in the interview. I think that kind of gave me the edge to get the role, to be honest.” Like Wilson, D’Alberti found that his previous work as a marketer helped him secure his first developer role—which was ironic, he felt, given that he’d partially chosen to switch careers because he hadn’t been able to find an English-language marketing job in Japan. “I had my first interview with the CEO,” he told me, “and this was for a Japanese startup that was building chatbots, and they wanted to expand into the English market. So I talked with the CEO, and he was very excited to get to know me and sent me to talk with the CTO.” The CTO, unfortunately, wasn’t interested in hiring a junior developer with no professional experience. “And I thought that was the end of it. But then I got called again by the CEO. I wanted to join for the engineering position, and he wanted to have me for my marketing experience.” In the end we agreed that I would join in a 50-50 arrangement. I would do 50 percent of my job in marketing and going to conferences and talking to people, and 50 percent on the engineering side. I was like, ‘Okay, I’ll take that.’ This ended up working better than D’Alberti had expected, partially due to external circumstances. “When COVID came, we couldn’t travel abroad, so most of the job I was doing in my marketing role I couldn’t perform anymore. “So they sat me down and [said], ‘What are we going to do with you, since we cannot use you for marketing anymore?’ And I was like, ‘Well, I’m still a software developer. I could continue working in that role.’ And that actually allowed me to fully transition.” DON’T make these mistakes It was D’Alberti’s willingness to compromise on that first development role that led to his later success, so he would explicitly encourage other career-changers to avoid, in his own words, “being too picky.” This advice is based, not just on his own experience, but also on his time working as a teaching assistant at Le Wagon. “There were a couple of people who would be like, ‘Yeah, I’d really like to find a job and I’m not getting any interviews,’” he explained. “And then we’d go and ask, ‘Okay, how many companies are you applying to? What are you doing?’ But [they’d say] ‘No, see, [this company] doesn’t offer enough’ or ‘I don’t really like this company’ or ‘I’d like to do something else.’ Those who would be really picky or wouldn’t put in the effort, they wouldn’t land a job. Those who were deadly serious about ‘I need to get a job as a software developer,’ they’d find one. It might not be a great job, it might not be at a good company, but it would be a good first start from which to move on afterwards. Asakura also knew some other bootcamp graduates who struggled to find work. “A major reason was a lack of Japanese language skills,” he said. Even for junior roles, many companies in Japan require at least conversational Japanese, especially domestic ones. On the other hand, if you prioritize learning Japanese, that can give you an edge on entering the industry: “Many local companies are open to training junior developers, as long as they see your motivation and you can communicate effectively. International companies, on the other hand, often have stricter technical requirements and may pass on candidates without degrees or prior experience.” Finally, Hendricks said that during his own job hunt, “Not living in Tokyo was a problem.” It was something that he was able to overcome via diligent digital networking, but he’d encourage career-changers to think seriously about their future job prospects before settling outside a major metropolis in Japan. Their top advice I asked each developer to share their number one piece of advice for career-changers. D’Alberti wasn’t quite sure what to suggest, given recent changes in the tech market overall. “I don’t have clear advice to someone who’s trying to break into tech right now,” he said. “It might be good to wait and see what happens with the AI path. Might be good to actually learn how to code using AI, if that’s going to be the way to distinguish yourself from other junior developers. It might be to just abandon the idea of [being] a linear software developer in the traditional sense, and maybe look more into data science, if there are more opportunities.” But assuming they still decide ‘Yes, I want to join, I love the idea of being a software developer and I want to go forward’ . . . my main suggestion is patience. “It’s going to be tough,” he added. By contrast, Hendricks and Wilson had the same suggestion: if you want to change careers, then go for it, full speed ahead. “Do it now, or as soon as you possibly can,” Hendricks stated adamantly. His life has been so positively altered by discovering and pursuing his passion, that his only regret is he didn’t do it sooner. Wilson said something strikingly similar. “Do it. Just do it. I went back and forth a lot,” he explained. “‘Oh, should I do this, it’s so much money, I already have a job’ . . . just rip the bandaid off. Just do it. You probably have a good reason.” He pointed out that while starting over and looking for work is scary, it’s also possible that you’ll lose your current job anyway, at which point you’ll still be job hunting but in an industry you no longer even enjoy. “If you keep at it,” he said, “you can probably do it.” “Not to talk down to developers,” he added, “but it’s not the hardest job in the world. You have to study and learn and be the kind of person who wants to sit at the computer and write code, but if you’re thinking about it, you’re probably the kind of person who can do it, and that also means you can probably weather the awful six months of job hunting.” You only need to pass one job interview. You only need to get your foot in the door. Asakura agreed with “just do it,” but with a twist. “Build in public,” he suggested. “Share your progress. Post on GitHub. Keep your LinkedIn active.” Let people see your journey, because even small wins build momentum and credibility. “To anyone learning to code right now,” Asakura added, “don’t get discouraged by setbacks or rejections. Focus on building, learning, and showing up every day. Your portfolio speaks louder than your past, and consistency will eventually open the door.” If you want to read more how-tos and success stories around networking, working with recruitment agencies, writing your resume, etc., check out TokyoDev’s other articles.
