Career paths for software developers have always been a touch problematic. 

Early on, you started out as a junior developer, and maybe there were ladder rungs that got you raises until you became a senior developer. But there was typically a ceiling to that, leaving you with little choice but to move into a management position if you wanted to continue to advance and make more money.

On top of that, promoting developers to be managers is often less than optimal for the company or the developer in the long run. Many of the qualities that make a good developer don’t always translate into being a good people manager. And certainly, many software developers want to continue to write code and not have to worry about the bureaucracy and paperwork that often comes with management. Plus, it hardly seems optimal to take your best coders and tell them to stop coding. 

The industry dealt with this by creating technical positions such as “Architect” and “Staff Developer” and “Chief Scientist.” That works well, but then these positions often lead to doing less programming and attending more meetings.

No matter what the title or role, the simple fact of the matter is that the more senior you get, the more you’ll be dealing with other people. “Tech Leads” have to supervise the work of other developers. Maybe you aren’t responsible for managing their careers or writing their performance evaluations, but you are responsible for making sure their code is up to snuff.

You’re the boss

It will come as no surprise that agentic coding changes this entire dynamic.

We don’t write much code anymore. And we are all too aware that coding agents aren’t perfect. Like humans, they make bad decisions, write bugs, and do things they weren’t asked to do. They need clear instructions, wise guidance, and the right working environment. You need to keep an eye on your agents to make sure they are on track and headed in the right direction. 

One might even say that you need to, ahem, “manage” your coding agents. 

And in that sense, we are all managers now. “A coding agent is most useful when you treat it more like an employee than an autocomplete tool,” says Jim Bourke, founder and CEO of Zide Software, producer of a development tool that treats developers more like managers than coders. “It needs a clear assignment, the right context, a safe place to work, checkpoints, and a way to evaluate the result.”

How you deal with coding agents isn’t all that different from how you would deal with a real live developer. You have an array of choices to make about who/what will write the code, what they will be building, and when their work can be called finished. You have to guide them, give them clear instructions, review their code, and decide when that code is ready to be checked in. 

Career twists and turns

All of that should sound pretty familiar to managers and individual contributors alike. In fact, one might argue that this is the job now — managing coding agents. Even the most junior of developers will be managing a “developer” in the future.

What does that mean for the career path of a person who manages coding agents all day? I hate to say it, but I don’t know and I don’t think anyone can say for sure. The set of skills required to successfully lead a “team of coding agents” compared to those needed to manage a team of real live people overlap, but they are not congruent. 

It may be that managing coding agents is an innate talent, leading to some junior developers suddenly outproducing seniors. Or maybe it will be a skill that needs to be carefully nurtured and grown under the mentorship of an experienced manager. It’s hard to say. And how the career ladder will look going forward, and exactly what skills will be rewarded, are questions I don’t think we can answer right now.

Everything is so new and changing so fast that it’s all a blur at this point. 

Wherever we may be headed, I don’t envy the person who will have to rewrite all those job descriptions.

I guess I’m a Go developer now.

My first programming language was BASIC. My seventh-grade math teacher, Mr. Schulte, taught BASIC to us on Fridays. He gave us programming assignments for homework during the week. Some of us loved it so much we stayed after school to play games and create extra programs, including our own crude, text-based adventure games. I remember hearing a story about a crazy new language called Pascal that didn’t have line numbers. How in the world would that work?

Years later I became a Pascal programmer — an ardent one. So ardent, in fact, that I would argue for hours with Visual Basic developers on CompuServe, AOL, and Usenet, telling them how Turbo Pascal, and then Delphi, was clearly a superior language. I was completely self-taught — if you count all the help that others gave me as teaching myself. I wrote shareware, became pretty competent, and eventually started helping others. 

People would tell me I should branch out and learn other languages — C++ or C#. But I wanted to be a master of one instead of a jack of all trades. Besides, we were all Windows developers and there was no better tool for writing Windows applications than Delphi. It became a point of pride for me, and I would stick up for Delphi and its company Borland no matter what. It got so bad that my friends would tease me, calling me “Baghdad Nick” after the famously optimistic Iraqi foreign minister during the Iraq War. 

Delphi by day

Looking back, I was foolish. I did become a pretty good Object Pascal programmer, but I would have benefited from learning JavaScript or a functional language. I did eventually learn TypeScript and a bit of C#. (I guess I was following Anders Hejlsberg around…) 

But if you were to ask me to this day what kind of code I write, I’d say I’m a Delphi developer. Indeed, that is my day job. I understand Delphi deeply, knowing all the nuances and insider tricks to making the language my own.

But over the course of a day or two, I’m now a Go developer, too. 

If coding all day isn’t enough, I have taken on a side project for a friend. I’ve been writing Delphi code for him for a while, but now he wants to shift gears. He has asked me to build a cross-platform application for his company written in Go and Wails Version 3. Now, I’m no Go expert. In fact, I only have a passing familiarity with the language. I can decipher what is going on, but I’m far from understanding the intricacies of what makes Go tick.

But that doesn’t really matter anymore, does it?

Claude bootcamp

I asked Claude to give me a tutorial on Go and Wails. It did a great job, quickly bringing me up to speed on the basics. (How cool is it that you can so easily turn a struct into a JSON object?) I described what I wanted, and asked for recommendations for libraries. The project uses Go for the “back end” and React on the “front end.” (I use the quotes because those “ends” are actually all built into a single binary.) 

In about an hour I came to understand the architecture and got a basic application up and running. I told Claude what I wanted, and it obliged. I described the basic data structures and objects needed, and Claude wrote them quite elegantly. I didn’t actually write a line of code, but there the project was, in all its glory. Go, TypeScript, and HTML. 

Claude managed the Git repository and even created a nice little CI/CD pipeline for me, building binaries for Mac, Linux, and Windows, all in one step.   

I went from being basically ignorant of the Go language to having a moderately sophisticated application in a day.

The thing is, I’m still not that good at Go. Not that good at all. But I’m a Go programmer nonetheless. Maybe next weekend I’ll become a Python programmer.

IT industry experts and analysts are still trying to piece together Nvidia’s surprise plan to pay $12.9 billion for open-source AI company Hugging Face.

Nvidia dominates AI with its GPUs, and the company generates billions of dollars in revenue through a proprietary approach to the fast-moving technology. Hugging Face, on the other hand, hosts open models and has been a neutral player between chip vendors and model labs.

“This is about Nvidia having more say in how the stack gets built,” said Stephanie Walter, analyst at Hyperframe Research.

Hugging Face is wildly popular with developers, and Nvidia is buying early influence with that crowd. “You have a better chance of being part of the production environment later,” Walter said, adding that she wasn’t sure how Nvidia reached a nearly $13 billion price tag for the acquisition.

“Hugging Face has near-uncontested market primacy over where developers go for open-weight model releases. Now Nvidia owns that,” said Mark Petty, senior director analyst at Gartner.

Nvidia’s chase for developers should force IT decision-makers to review how much of the AI stack they control, said Hector Liu, director of Institute of Foundation Models’ Silicon Valley Lab. IFM is part of the Abu Dhabi-based Mohamed bin Zayed University of Artificial Intelligence.

Liu said CIOs should ask themselves three questions: “Can you run the model on hardware you already have, without a dependency you didn’t choose? Can you see how it was built?” And, “is the license one you can build a business on?

“A model that passes all three is durable, no matter who buys whom next year,” Liu said.

IFM’s latest K2 Horizon model, which was introduced on the same day Nvidia’s deal was announced, is hosted on Hugging Face. The open model was built to answer all of those questions.

K2 Horizon runs on AI hardware from Nvidia, AMD, Cerebras, and major cloud providers, said Liu, who doesn’t expect that to change. “Nvidia has said Hugging Face stays an open platform for every builder and every accelerator, and we’ll take that at face value,” Liu said.

Nvidia pledged to maintain Hugging Face’s hardware and model independence, and said its compute won’t be required. 

Even so, Nvidia isn’t paying nearly $13 billion for a model repository, said Jake Newfield, CEO at Hermetiq — it’s buying the front door to open AI.

(Hermetiq develops AI build and code observability tools.)

AI-generated output is becoming abundant and the infrastructure that makes it testable, reproducible and deployable is becoming strategically valuable, Newfield said. “Nvidia can accelerate it with capital and compute, but the real test is operational neutrality,” he said. 

That involves assessing whether competing hardware remains equally supported across the tooling, benchmarks and deployment paths developers actually use, Newfield said.

Beyond distribution, Nvidia is also buying Hugging Face for data, Petty said. That data showed that agents overtook humans as its largest traffic source in July, the kind of insight that could prove valuable down the road.

“Every model pulled tells Nvidia what the market wants next,” Petty said.

Nvidia has every reason to grow demand for open models and to keep them cheap, Petty said. “That’s good for enterprises, as it prevents market consolidation around a small number of proprietary model owners,” Petty said.

Closed and open models will coexist and lead to a world “where you’re going to continue to train these models and run these models at scale,” Justin Boitano, Nvidia’s vice president for Enterprise AI, said in a press conference after the deal’s announcement.

Nvidia will benefit “through the training that’s done and the inference that’s done on our hardware as models get diffused into the ecosystem at scale,” Boitano said.

That’s one motivation to keep the ecosystem open and neutral, so “developers can work wherever they want to work,” Boitano said.

Open source makes AI more accessible by lowering the barriers to experimentation and adoption, said Jon Carvill, senior vice president of marketing at AI chip maker Nuvacore. “Bringing Nvidia and Hugging Face closer together should help accelerate that choice, access and innovation,” Carvill said.

But there are still unanswered questions around whether Hugging Face will remain open and how much proprietary control Nvidia might exert, said Jack Gold, principal analyst at J. Gold Associates.

Microsoft traveled a similar path with its acquisition of open-source repository GitHub, which “did not really pan out as well as Microsoft hoped,” Gold said. “With Nvidia’s acquisition, will it still be as open to competitive hardware-software access, or will there be some barriers employed?”

Four months ago, a front-end engineer on my team looking to make upgrades to a product or feature would have filed a ticket and waited for the infrastructure group to unblock them. They might have lost a day, sometimes a week. Today, that same engineer makes changes themselves. The code is occasionally brittle, but it works, and the end result ships in a fraction of the time it used to take.

That small story is unfolding inside nearly every engineering organization right now. While some celebrate the sudden fact that one person can do the work of five, others are focused entirely on tech industry layoffs. Both perspectives skip the question I find more interesting: What happens to mastery when every engineer can suddenly do everything?

For two decades, we have described strong engineers as T-shaped. The horizontal bar represents breadth, which is a working familiarity across many areas. The vertical bar represents depth, the real command of one domain earned over years. Agent tooling has stretched that horizontal bar wider than ever before. My concern is the vertical bar, which is quietly getting shorter.

Consider what is now possible in a single quarter. With the right agent harness, one engineer can stand up a billing system, a data connector framework, regional and organizational tenancy infrastructure, or a consumption-based pricing implementation. The pull requests pass review. The tests are green. All looks good. But green tests cannot tell you if the person who shipped that work understood why the system needs redundancy in one specific place, where its failure modes are hiding, or which trade-offs the model made silently on their behalf. The pattern recognition that comes from watching systems fail over many years is suddenly weighted differently than it was even 12 months ago. Our industry has not caught up to that shift.

When the interview stops measuring judgment

The first place this surfaces is hiring, a trend that should concern anyone who has built a team. Traditional coding interviews were always an imperfect proxy for engineering judgment, but agent tooling completely obliterates them. If a candidate can produce a working solution in 20 minutes that would have taken two hours a year ago, the exercise no longer measures technical competence. It just measures how well a coder can prompt an agent.

At Thread AI, we have responded by widening what we look at when we interview job candidates. Our process moves across coding exercises, problem decomposition, system architecture, and behavioral components, with the weighting shifting by role. We allow AI assistance only in specific sections because our engineers still need to be able to operate without it. Some of our work happens in secure environments where you cannot lean on an agent to debug for you. What we’re really testing for now is judgment under ambiguity — the ability to notice when an agent’s output is confidently wrong — and the depth to predict where a system will break before it breaks.

Hiring teams that fail to make this shift will fill their rosters with false positives. They will hire people who interview like experts but struggle the first time a system behaves in a way the model did not anticipate. Ultimately, these companies will miss out on top-tier talent, and they won’t discover the misstep until it’s too late.

Confusing velocity with understanding

That brings me to a larger risk: the rise of false expertise as a category of its own. Historically, the reasoning has gone, “I built a proof of concept, therefore I am an expert.” I have watched versions of this appear in technical leadership, in investment decisions, and in policy conversations about AI. It travels well because the artifact looks real. A working demo is highly persuasive, even when the person behind it only half-understands how it functions.

The problem is bigger than one false expert shipping one bad product; an organization can absorb that. The real risk is a generation of consequential decisions being made by people who have confused velocity with understanding. You can already see the cultural scaffolding being built around this with the celebration of the “idea guy,” and the sudden fashion for invoking “taste” as a substitute for knowing how a system actually works. Those of us shaping tooling, hiring norms, and regulations have a narrow window to set better defaults before this pattern hardens into the way the industry operates.

Depth and breadth, held together

This is the path we’ve been walking at Thread AI since before the latest wave of tooling arrived.

To ground this in a specific example: I have spent 15 years building complex systems. I worked at Goldman Sachs through the financial crisis and the early Dodd-Frank infrastructure, moved critical payment systems into the cloud at The New York Times when that ground was still new, and built the system of record for model training and evaluation at Palantir across highly regulated environments in defense, health, and finance. This experience is the superpower that lets me course-correct an agent when it produces confident-but-wrong output.

I felt this sharply not long ago while scoping consumption-based pricing in a single quarter. The agents did an enormous amount of the heavy lifting, and at some point, I realized that my largest contributions to the effort were knowing where the system would fail and steering around it before we got there. I have also seen how organizations have built large teams around efforts like these in the past. Someone earlier in their career or relying purely on AI guidance would not have had that instinct to draw on. That is the part the public conversation keeps missing.

Every engineer at Thread AI, regardless of seniority, is expected to be a builder at heart. Our people own outcomes across compute, data, and the organizational and identity primitives that hold the product together, all without the traditional product-manager and project-manager scaffolding around them. Our model works only because the people in those seats have the depth to know what they do not know, and the breadth to fill the gaps with agents. They use the tooling instead of being used by it.

AI doesn’t replace deep understanding

The core issue facing organizations today is not whether AI will replace engineers. That question has been answered dozens of times this year with varying degrees of nuance, and it has stopped being interesting. The more useful question for anyone running a company is whether we are protecting the people who understand our systems deeply enough to recognize when the machines are wrong.

In our company, the answers have been to move toward explicit end-to-end ownership, and to hire for depth and breadth together rather than treating them as a trade-off. Layoffs dominate the headlines because they are an easy narrative, but they describe a symptom rather than the actual choice in front of us. The real choice is whether we let breadth quietly stand in for mastery, or whether we build organizations that keep human judgment in the loop on purpose.

In an era when software can be generated faster than it can be understood, the companies that hold onto what is human, verifiable, and deeply understood will be the ones still standing when the brittle parts give way.

I hope you’ll indulge me this week as I take a break from my usual rantings about agentic coding and meander down memory lane.

I learned to code BASIC in the mid-1970s at my progressive junior high school. In math class. We took Fridays to learn about line numbers, loops, statements, and the amazing GOSUB, which was as close as we got to a function call. It strikes me that it was pretty early in the whole tech world to be teaching seventh graders to program, and I feel lucky.

Coding faded into the background for me through high school, but soon afterward the arrival of Windows 3.0 and modems made writing software fun again. You could even earn a little profit. CompuServe, AOL, and bulletin board systems (BBS) created a market for shareware.

I bought a copy of Turbo Pascal for Windows 1.0 from Borland and a copy of Mastering Turbo Pascal 6 by the great Tom Swan, and I learned the Pascal syntax. I remember being delighted to discover that Swan had also written a book specifically for Turbo Pascal for Windows, and I devoured that too. 

In search of SYSBACK

I soon came up with an idea for a shareware project — System Backup. Any of you who can remember back to the DOS and Windows 3.x days will remember that there were four files — AUTOEXEC.BAT, CONFIG.SYS, WIN.INI, and SYSTEM.INI — that were crucial to one’s setup. You’ll also remember that it wasn’t uncommon to twiddle with these files to eke out an extra measure of performance from the system. Backing those files up was critical to the tweaking, so I wrote SYSBACK.EXE to do the job quickly and easily. 

Windows 3.1 introduced the amazing feature of *.wav files — sound through your tinny PC speaker! That led me to write WAVSHELL.EXE, which listed all your sound files and made them easy to play.

I guess I didn’t have much faith in the value of my shareware because I released it into the wild of the pre-internet shareware market for a measly $2. People soon started sending me checks in the mail — my address was in the About Box, with a plea to pay for the software. Soon I added a licensing scheme and a “nag screen” that would go away if the user entered a valid license key. I actually made a bit of money.

Eventually both programs became unnecessary as Windows grew more functional, and I abandoned things. I’m sure all that code is on a hard drive in a landfill somewhere. 

But that doesn’t mean that SYSBACK and WAVSHELL don’t live on!

Last week, on a whim, I went searching to see if I could find any remnants of my glory days. Although it took a while, I was delighted to discover that both programs had clung to life in the dark crevices of the internet. 

I found WAVSHELL.ZIP and SYSBACK.ZIP and downloaded them. Sure enough, there were the files — the 16-bit Windows executables, along with the accompanying READMEs formatted for Windows Write, the simple word processor that came with Windows 3.1.

Return to Windows 3.1

So, what to do? Naturally I fired up Claude and asked how to get all this running. It suggested I give Oracle VirtualBox a try. At first I tried an open-source DOS version, but soon ran into conflict with memory managers and Windows. Tweaking CONFIG.SYS like the old days didn’t seem to make a difference.

This led to downloading a set of *.img files of MS-DOS 6.22. I mounted the first disk in the A: drive of the virtual machine. (For you youngsters, the A: drive was a floppy disk — maybe you remember those?) I had to do a virtual version of the old disk shuffle for the three floppies, and then do the same to install Windows. Everything installed and ran like clockwork, and soon enough, Windows 3.1 was up and running. 

Then, of course, I had to figure out how to get the files from my modern system to this ancient OS. This led me to WinImage, a shareware program (!) that builds floppy disk images for you. I built an image, copied the files onto the “disk,” and mounted it in the A: drive in the VirtualBox machine. I copied the files to the virtual hard drive, and behold!

Foundry

There they are, in all their glory. I have to say, it was quite a thrill. And they actually work!

Anyway, it was fun to remember all those halcyon days of CompuServe, 2400 BAUD modems, and getting checks from strangers in the mail. It seems strange to me that 35 years from now, some software developer will be writing a column about the deep dark past when people used to actually write code, argue about what programming languages were best, and, who knows, even had to type things out by hand.

For a long time, I thought of observability as something mainly owned by backend, platform or site reliability teams. Frontend engineers built the interface, handled browser behavior and called APIs. When something failed deeper in the system, another team looked at server logs and infrastructure dashboards.

That division works until the application is technically available, but the user experience is not.

A page may load while its most important data arrives several seconds late. A request may succeed after multiple retries, leaving the user staring at a spinner. One cloud service may slow down while the rest of the page continues working. From an infrastructure perspective, nothing may qualify as an outage. From the user’s perspective, the application is already failing.

As I gained more experience building applications that depended on cloud services and APIs, my view of frontend ownership changed. A frontend team does not need to operate every service it depends on, but it does need enough visibility to understand how those services affect the experience it delivers.

Observability gives frontend engineers that visibility. It helps connect what happens in the browser with what happens across the systems behind it. More importantly, it gives teams evidence they can use not only to debug problems, but also to make better decisions about how the frontend should behave when dependencies are slow, unavailable or inconsistent.

The browser sees a different version of the system

Server-side monitoring tells us what happened inside a service. It does not always tell us what happened across the user’s complete journey.

A backend dashboard might show that an API responded in 300 milliseconds. The browser may still take much longer to display useful content because of network latency, JavaScript execution, rendering work or additional requests. A successful response can also produce a broken experience if the returned data is incomplete or the interface fails while processing it.

This is why client-side telemetry matters. Browser error reporting can capture exceptions that never reach a server. Performance measurements can show how long users wait for content to become visible or interactive. Request data can reveal which dependencies are slow, unreliable or frequently retried.

Standard browser APIs provide useful starting points. The W3C User Timing API allows developers to mark and measure meaningful operations in an application. A team can measure how long it takes to load a dashboard, complete a search or render a critical section of a page.

Web Vitals can also help teams examine loading performance, responsiveness and visual stability using measurements tied more closely to the user experience. These metrics are useful because they move the conversation beyond whether a request succeeded. They help answer whether the page became useful quickly and respond when the user tried to interact with it.

The goal is not to collect every browser event. That can produce a large amount of data without producing much insight. It is better to begin with a small set of questions.

How long does the user wait before the main content appears? How often does a form submission fail? Which request prevents a page from becoming usable? Are users on certain devices or network conditions affected more often?

These questions make telemetry easier to design and easier to interpret. “The API is available” is a service-level statement. “The user can complete the task without an unexpected delay” is an experience-level statement. Frontend observability helps connect the two.

Logs and traces connect the frontend to its dependencies

Client-side logs are most valuable when they include enough context to reconstruct what the user was doing. A useful error record might include the application version, route, operation, request status and a correlation identifier. Browser information may also help when an issue affects only certain environments.

At the same time, frontend telemetry should be designed carefully. Logs should avoid form contents, authentication tokens, passwords and other sensitive information. Collecting more data does not automatically make an investigation easier. The right context is more useful than a large amount of unstructured information.

Correlation identifiers are particularly helpful. When the frontend includes an identifier with a request and that identifier continues through downstream services, teams can connect a browser failure to backend logs and distributed traces. Instead of comparing timestamps across several dashboards, engineers can follow one request across the system.

A distributed trace can show that a user action triggered an API gateway, an application service, a database call and another cloud dependency. It can also show where the request spent most of its time or where an error first appeared.

OpenTelemetry provides a vendor-neutral approach for generating and connecting telemetry such as traces, metrics and logs. It also supports JavaScript and browser instrumentation, which makes it relevant to frontend teams that want to connect browser activity with backend services.

Frontend engineers do not need to become observability platform specialists. They do need agreement with backend and platform teams on basics such as trace propagation, naming conventions, safe logging fields and where telemetry can be reviewed during an investigation.

Consider a page that occasionally loads without its main data. The frontend may record that a critical request timed out after several seconds. A correlation identifier from that request may lead to a trace showing that the gateway responded normally, but a downstream dependency exceeded its timeout.

Without connected telemetry, the report might remain, “The page sometimes does not load.” With connected telemetry, the team has a specific failure path, a measurable delay and enough evidence to decide what needs to change.

That evidence can support two actions. The service team can investigate the slow dependency. The frontend team can improve the experience by adding a timeout state, retry option or partial fallback. Observability makes both responses more precise.

Observability should influence architecture, not only debugging

The immediate benefit of observability is faster incident investigation. The larger benefit is better architectural decision-making.

When telemetry repeatedly shows that one dependency is slow, the frontend team can reconsider how tightly the interface depends on it. The page might render primary content first and load secondary information later. Cached data might be acceptable for a noncritical section. A timeout might lead to a smaller fallback instead of blocking the entire screen.

Observability can also expose hidden coupling. If unrelated components fail whenever one shared request slows down, the page may have been designed as a single loading unit. Breaking the experience into independently recoverable sections can make the interface more resilient.

The same evidence can improve retry behavior. Automatic retries may help with a temporary network failure, but they can also add more traffic to an already slow service. Telemetry can show whether retries recover requests, how long the recovery takes and whether users leave the page before it succeeds.

Service-level visibility matters as well. Frontend teams should understand the availability and latency expectations of the services they use. They should also understand what those services return during partial failures.

If a dependency may respond slowly, the interface needs a loading strategy. If data may be stale, the interface needs to communicate freshness. If a service is optional, the page should not collapse when it is unavailable.

Good observability also improves conversations between teams. Instead of saying, “The page feels slow,” frontend engineers can explain which user action is affected, how often it happens and where the delay appears. Debugging becomes a discussion based on evidence rather than guesswork.

A practical starting point can be small. Capture unhandled browser errors. Measure a few important user journeys. Record failures for critical network requests. Propagate a correlation identifier across frontend and backend systems. Review those signals with the teams that own dependent services.

From there, instrumentation should grow in response to real questions. Add a measurement when a workflow is difficult to understand. Add a trace when a request crosses several systems. Add a dashboard when a signal is important enough to review regularly.

Frontend observability is not about turning every frontend engineer into an operations engineer. It is about recognizing that the browser is part of the production system and often the only place where the complete user experience is visible.

When frontend teams can connect what users experience with the services behind it, they can debug more effectively, design interfaces that degrade gracefully and make better architectural decisions. Observability becomes more than a way to explain incidents. It becomes an input into how frontend systems are designed.

OpenAI is selling its first hardware — without any help from Jony Ive. It describes the Codex Micro as a “command center for agentic work” but it’s really a 13-switch wireless keyboard customized to help developers keep tabs on what their Codex agents are doing. It costs $230.

The keyboard has 13 mechanical switches (one keycap covers two of them by default), a rotary encoder, joystick, and RGB backlighting around the whole keypad and individual keys. It comes with 32 customizable icon keycaps.

OpenAI claims that the Codex Micro is a serious business tool: The command keys enable Codex users accept changes, reject outputs, push-to-talk, start new chats, and trigger custom actions. The rotary encoder can be used to dial up the “brainpower” allocated to tasks — or in more conventional terms, how many tokens to allocate to reasoning on a task. And the RGB lighting can provide feedback on how various tasks are progressing. And the RGB lighting under the “agent” keys can provide feedback on how various tasks are progressing.

The Codex Micro’s manufacturer, Work Louder, already has a similar device on the market, the Creator Micro, which offers similar functionality, but without the colorful keys. It costs $56 less than the Codex Micro, however.

The Codex Micro will fit in snugly with OpenAI’s other merchandise, where using Codex is as much about a fashion statement as a technological choice.

Linus Torvalds has a complicated relationship with AI, seeing both its good and bad points. But his latest remarks on the usefulness of AI may have raised a few eyebrows in open-source circles.

Just a few weeks after the Linux founder complained that a “continued flood” of AI-generated vulnerability reports had made the Linux kernel security mailing list “almost entirely unmanageable”, he has come to see the advantages of the technology.

“Linux is not one of those anti-AI projects,” Torvalds wrote in an email response to Linux Kernel senior engineer Roman Gushchin, archived at Kernel.org.

“It can also be a somewhat painful tool, both for maintainer workloads and just from a ‘it keeps finding embarrassing bugs’ standpoint,” he said of the use of AI in security scanning. “The solution is to make sure those LLM tools help maintainers instead of just causing them pain.”

Developers should be free to choose whether they use AI, he said. “We’re not forcing anybody to use it, but I will very loudly ignore people who try to argue against other people from using it.”

Torvalds’ measured support for AI does not come completely out of the blue: Around the same time that he was complaining about AI distorting security maintenance, he also spoke about its usefulness, claiming that it could improve programmer productivity by a factor of 10.

I was blessed with a terrific high school English teacher. Ms. Jewel was funny, kind, interesting, and tough on us. I can still spell “ecstasy” on the first try because of her. One of the more memorable lessons she taught was a “Hemingway and Fitzgerald” module. 

I loved the short stories of both, but Hemingway’s work always stuck out for me. It’s cliché to say that Hemingway was terse, but we only say it because it is true. He could pack more into a page than most writers. He didn’t waste a syllable. 

Software developers are soon going to have to take a lesson from Hemingway.

It’s not hard to be concise in code. You have to be, by design. The compiler won’t put up with any throat-clearing and jibber-jabber. You can’t meander. You have to use a very strict set of words and symbols, and you have to use them in a defined way. 

Thanks to agentic development, we don’t write code anymore. But we are writing for the agents. A lot. 

All about the spec

Let me explain. Claude Code, Codex, Copilot, and the rest all love to be “spoken” to in Markdown. We used to define our code with unit tests and specifications written for humans. Now, it’s all about the spec. And the spec needs to be both complete and concise. 

It needs to be complete in the sense that if you leave something out or forget to define something, the agent will very likely fill in the gaps for you. Forget a feature or requirement, and the agent will go off confidently and almost certainly in the wrong direction.

At the same time, you need to be concise. Because if you are too effusive, you may give the agent ideas that you don’t want it to have. If you write like Fitzgerald — lush and expansive —  the agent will be off and running in a direction you can’t be sure about. 

Our compilers will stop cold if we aren’t precise and concise. Our agents? They will proceed with confidence, diligently producing a result that looks great but isn’t what we want.

So we need to learn to write like Hemingway and pack as much meaning into as few words as possible. Or, as Paul Graham said:

Foundry

Let’s be clear

For years, we’ve been writing semi-vague Jira tickets and expecting our fellow humans to fill in the gaps and “get the gist” of what we were trying to do. We don’t have that luxury anymore. Developers who aren’t able to move on from “Jira-speak” to “Agent-speak” are going to struggle. If we don’t follow Graham’s advice in writing those specs, who knows what we’ll get.

Maybe someday agents will know the ins and outs of our business well enough to “know what we mean,” but they can’t today. The time we used to spend coding now needs to be spent perfecting our new craft of writing precise specifications for our agents to execute.

Every listicle ever written on “How to be a Great Developer” says you need to be a great communicator — but that was communication with other humans. 

Ms. Jewel always taught us that our writing is only as clear as our thinking. Our compilers forced us to write clearly. Our coding agents won’t do that. I’m sure there are many developers out there now who wish they had listened more closely to their high school English teacher.
