Diagrams and screenshots help, but they often compensate for prose that failed to produce an image on its own. Docs are visible when the reader can close their eyes and still see what the page described." #Documentation #DocsAsProduct #SoftwareDocumentation #TechnicalWriting #SoftwareDevelopmentMiguel Caetano compartilhou issoDocs are often thought of as a purely functional artifact, a packet of content that, when it works, it’s not remembered at all. Those who consume documentation, however, can tell whether a manual or docs site pleases our mind and senses in ways that others don’t. We know the feeling of a page that lands and the feeling of a page that drags. Now, if we agree that docs can be a product, why not seek to build them in a way that pleases consumers? If docs are the entry point for products, shouldn’t they produce a positive feeling that makes users return to them more often and trust them more? Docs that make users feel empowered, or that leave them with learnings. Docs that heal. Our craft has hyperfocused on function for so long that the discourse has gotten brutalist. We argue about tools and commas but don’t ask what makes users return to the docs. I’m writing this post to open up the question to debate, and perhaps to provide myself with inspiration.

Miguel Caetano compartilhou isso"It is worth remembering that most art has always been slop. When I did my PhD on early modern drama, my supervisor made me read every tragedy written in English until 1640. The process was grueling but instructive. Almost all of them, the fruits of the definitive art form of the greatest period in English literature, were garbage. Go and watch what was on TV in the 80s, if you want a more contemporary example. There is good news for humanists in the arrival of AI. According to the New York Fed, unemployment for computer science graduates sits at 6.1%, while for art history majors, the number is 3%. Merely practical education will be of limited value in the AI future. To make yourself merely technically useful to a company or an industry is to make yourself vulnerable to replacement by automation at any moment. Thinking, creating, understanding – these cannot be replaced, certainly not by artificial intelligence. Trust me. I’ve tried. The kids I overheard on the playground knew the difference between language that sounds meaningful and language that is meaningful. Do you? Does the literary community? Two roads diverge into a sloppy wood: one goes through what machines can do, the other goes through what only people can do. To write now is to wage war against cliche as usual, just this time with the AI and against it." https://lnkd.in/ejwdRNeM #AI #GenerativeAI #Writing #AISlop #LiteratureI wrote a novel using AI.

Miguel Caetano compartilhou isso"Leading models are now “nearly indistinguishable” from each other when it comes to performance, the Stanford HAI report notes. Open-weight models are more competitive than ever, but they are converging. As capability is no longer a “clear differentiator,” competitive pressure is shifting toward cost, reliability, and real-world usefulness. Frontier labs are disclosing less information about their models, evaluation methods are quickly losing relevance, and independent testing can’t always corroborate developer-reported metrics. As Stanford HAI points out: “The most capable systems are now the least transparent.” Training code, parameter counts, dataset sizes, and durations are often being withheld — by firms including OpenAI, Anthropic and Google. And transparency is declining more broadly: In 2025, 80 out of 95 models were released without corresponding training code, while only four made their code fully open source. Further, after rising between 2023 and 2024, scores on the Foundation Model Transparency Index — which ranks major foundation developers on 100 transparency indicators — have since dropped. The average score is now 40, representing a 17 point decrease. “Major gaps persist in disclosure around training data, compute resources, and post-deployment impact,” according to the report." https://lnkd.in/eaxERmhW #AI #GenerativeAI #LLMs #OpenWeights #OpenSource #Transparency #HallucinationsFrontier models are failing one in three production attempts — and getting harder to auditFrontier models are failing one in three production attempts — and getting harder to audit

Miguel Caetano compartilhou isso"TLDR: I pointed Claude Opus at Discord’s bundled Chrome (version 138, nine major versions behind upstream) and asked it to build a full V8 exploit chain. The V8 OOB we used was from Chrome 146, the same version Anthropic’s own Claude Desktop is running. A week of back and forth, 2.3 billion tokens, $2,283 in API costs, and about ~20 hours of me unsticking it from dead ends. It popped calc. Anthropic’s announcement of Mythos and Project Glasswing set the tech sphere on fire. On one side, skeptics called it another boy-who-cried-wolf moment, compute limits dressed up as safety theater, or just the most fearmongering AI marketing play yet. On the other, people were already talking about airgapping their servers. Whatever Anthropic’s play is, and whatever the armchair experts have to say about it, there’s truth underneath it. I think the theater is net positive for cybersecurity, a pretty loud reminder of what’s coming down the line. But I don’t want to make that claim from the same armchair as the thousands of newly minted cybersecurity experts who spawned on Twitter and LinkedIn overnight. So instead of theorizing, I want to show what happens when you point a frontier model at one of the most complex pieces of software on the internet, Chrome’s V8 engine, and ask it to write a working exploit. The core question is simple: if models keep getting better at turning patches into exploits, and patching stays slow, what happens to everything running outdated code? Whether Mythos is overhyped or not doesn’t matter. The curve isn’t flattening. If not Mythos, then the next version, or the one after that. Eventually, any script kiddie with enough patience and an API key will be able to pop shells on unpatched software. It’s a question of when, not if." https://lnkd.in/ew-mmaZ5 #AI #CyberSecurity #Anthropic #Chrome #Exploit #Claude #ClaudeOpusI Let Claude Opus Write a Chrome Exploit: The Next Model (Mythos?)

Miguel Caetano compartilhou istoMiguel Caetano compartilhou istoBenchmarks are saturated more quickly than ever. How should frontier AI evaluations evolve? In a new paper, we argue that the AI community is already converging on an answer: Open-world evaluations. These are long, messy, real-world tasks that would be impractical for benchmarks. Our new project, CRUX (Collaborative Research for Updating AI eXpectations), will run open-world evaluations on a regular basis. In our first experiment, we tasked an agent with publishing an iOS app to the Apple App Store. The agent made two errors but eventually succeeded after one manual intervention. The app is now live: https://lnkd.in/eq68AZfh We disclosed this to Apple a month ago. Open-world evals are especially useful for early indications of useful capabilities and early warnings about risks such as AI spam. Why this task? Many benchmarks test code writing, but publishing an iOS app involves much more: signing the app, publishing a privacy policy, filling out Apple’s forms, and navigating the review process. We were more interested in whether the agent succeeded at those real-world requirements than its coding ability. The agent fabricated a phone number when submitting the app for review. Interestingly, the number it used is one reserved for fictional use, such as in films. One possible reason is that we informed the agent it was being evaluated. For capability evaluations, we think preventing evaluation awareness is a lost cause, and we should just disclose evaluation details upfront. We are releasing over 1GB of logs from this experiment. These revealed the agent proactively strategizing to reduce cost, unanticipated failures, and limits imposed by operating systems on synthetic clicks for sensitive dialogs. Our hope is that the community will uncover other interesting behaviors. https://lnkd.in/ep77f5FG To be clear, we think benchmarks will continue to be helpful. But as capabilities improve, open-world evals will become important for complementary insights. We plan to run CRUX evaluations regularly. If you have ideas, we would love to hear from you: https://lnkd.in/ezvy2T_7 We are thrilled to have a fantastic team working on CRUX, from academic, industry, civil society, and government: Peter Kirgis, Stephan Rabanser, Andrew Schwartz, JJ Allaire, Rishi Bommasani, Magda Dubois, Gillian K.

Miguel Caetano publicou istoThe great thing that Claude Code - or OpenAI Codex - brings to technical writers is that they can assess the accuracy of any piece of documentation that relies on software code, by analyzing the relevant code base(s). This is extremely helpful because it definitely helps you fact-check your docs against the source code, namely to see if the Subject Matter Experts (SMEs) were bullshitting you or if the docs became outdated due to the cadence of new releases. Another advantage is that even if you work in an organization with its own QA team, you can help them catch bugs at an earlier stage of the Software Development Life Cycle (SDLC). For example, yesterday I found an inconsistency between how a certain behavior was coded in the backend and how that same behavior was interpreted by the frontend. And the best thing is that, since Claude Code does not entirely relies on neural networks but rather also uses regular expressions, the results have an higher degree of determinancy than the ones offered by common LLMs. Even though it's not perfect and you always have to tell it where to direct its attention (meaning the name of the most relevant repository) , this ability of taking advantage of a "Ai-based sniffer" for code is terrific. For all these reasons I believe that every technical writer that doesn't use Claude Code or a similar tool in its own regular workflows will be immensely disadvantaged. #TechnicalWriting #AI #GenerativeAI #SoftwareDocumentation #Claude #LLMs #GenerativeAI #ClaudeCode #SoftwareDevelopment #QA

Miguel Caetano compartilhou isso"A paper last month by LSE professor Luis Garicano and co-authors extends the idea that jobs are bundles of tasks, to consider whether the different activities in a job are a tightly bound bundle or something more akin to an itemised list of discrete activities. In the context of software, a contractor or junior hire generally falls into the latter group: these jobs are weak bundles, with daily work consisting mainly of writing code to spec — tasks that could be given to someone else (or AI) without any disruption to the workflow or the quality of the final product. Here, AI breaks off a large chunk of the job and leaves a role with substantially diminished scope (or obviates the need for that hire or contract). But senior developers, or coders working outside the tech industry in roles where their programming skills are combined with domain-specific expertise, tend to have jobs comprising tightly enmeshed and cross-functional tasks. Here extracting the coding part of the job from all the rest is much harder, so the bundle of tasks remains intact. Instead of becoming a competitor AI becomes an assistant, enhancing rather than eroding the job. This fits with the findings from Brynjolfsson and our own analysis that hiring for senior software roles continues to hold up better than for junior ones." https://lnkd.in/eJn46cSG #AI #GenerativeAI #Automation #Productivity #Programming #SoftwareDevelopment #Unemployment #Layoffs

Miguel Caetano compartilhou isso"Verbose changes. Nonsensical descriptions. Pull requests contributors can’t explain. AI is DDoS-ing open source software (OSS) with slop, and some maintainers are calling it quits. As Steve Croce, field CTO at Anaconda, a Python data science platform, tells The New Stack, “It’s having a profound effect on maintainer workload.” In response, maintainers are canceling bug bounty programs and introducing stricter contributor guidelines, he adds. Some projects, like Jazzband, have been forced to sunset altogether. Jannis Leidel, the lead maintainer and Python Software Foundation chairperson, writes that the “flood of AI-generated spam PRs and issues” made his project unsustainable. According to Kate Holterhoff, Ph.D., a senior analyst at the consultancy Red Monk, the barrier to entry is now extremely low, making it easier to game the traditional incentive model for participating in open source. As she tells The New Stack, “It’s putting the contract between maintainers and contributors in peril in ways that haven’t existed before.” For example, Rémi Verschelde, who oversees the open source Godot game engine, shares on BlueSky that dealing with AI slop is “draining and demoralizing.” Other project maintainers report growing apathy and wasted time responding to the deluge. To be fair, nearly all software developers now use AI, and many communities rely on it to produce legitimate fixes and contributions. But the volume of low-quality submissions is becoming unsustainable, especially given that 60% of maintainers are unpaid volunteers." https://lnkd.in/eDvmTpNa #OpenSource #FLOSS #AI #AISlop #VibeCoding #Programming #SoftwareDevelopment96% of codebases rely on open source, and AI slop is putting them at risk96% of codebases rely on open source, and AI slop is putting them at risk

One HN commenter catalogued what lived inside that function: the agent run loop, SIGINT handling, rate limiting, AWS authentication, MCP lifecycle management, plugin loading, team-lead polling via a while(true) loop, model switching, and turn interruption recovery. His verdict: this should be 8 to 10 separate modules. Nobody disagreed. QueryEngine.ts ran 46,000 lines. Tool.ts hit 29,000. commands.ts reached 25,000. The entry point main.tsx was 785 KB.

Miguel Caetano gostou dissoMiguel Caetano gostou dissoTechnical writers: Claude Code can absolutely write your docs. But you need to use judgement. I’ve discovered these tips: - Clone your frontend and backend repos and ask Claude to write reference documentation. This is the easiest lift for Claude, so it’s a great place to start (for both of you ;) - When writing procedural guides, have Claude write one version for agents and another for humans. The agent version will likely be pretty good. The one for humans…not so much. - Claude does not accurately document user facing flows, even when working from frontend repos. So, you’ll need to write the first draft of each user guide yourself. Then, ask Claude to use what you’ve written as a model. - I have found that Claude will simply duplicate the model article unless you explicitly tell it to verify each setting, option etc. Getting Claude to find the right balance between using your article structure while inserting facts from the repo can be a bit fiddly. - Once you’ve found the right balance, ask Claude to write a skill for generating that article. Tell it to never rely on previously known facts, and instead to always examine the repos before writing the article, since the repos may have been updated. Have Claude install the skill under .claude in your project. - Read the skill and make sure that it covers edge cases and anything else you know is necessary to create a quality article. Then, ask Claude to generate the article. Verify that Claude finds and uses the skill. - Follow this process for every article. Going forward, you can simply reclone your repo(s) and ask Claude to generate articles.

also of the true motives and rationales of those who identify as file-sharers:
- What rationales do they use for justifying the downloading of copyrighted content?
- What is their opinion regarding the consequences of their sharing habits in the lives of creators, publishers and the future of cultural creativity in general?
- What do they think of the enforcement measures proposed by copyright industries?
- What solutions and business models do they propose to businesses and trade associations representing rights holders?

Abstract: Often seen as the ultimate solution for the global problem of “online piracy”, streaming services have been replacing file sharing networks and sites as the preferred means of accessing online music. One example of their increasing popularity is the service provided by the Swedish company Spotify. Even though Spotify quotes several studies showing the alleged positive impact of its service in terms of reducing “online music piracy”, this paper aims to highlight the main obstacles facing an offer based on the democratization of access to culture presented by commercial streaming services supported by the culture industries. It draws on a comparative analysis of Spotify and a private file‑sharing community (a private BitTorrent tracker), based on the experience of using both services by an individual living in a peripheral country in the European Union like in Portugal.

Abstract: The new peer-to-peer (P2P) technologies have impacted the film industry, which advocates sanctions against the downloading and sharing of products found on the Internet. But the economic effect of file sharing on the film industry remains difficult to determine. In this article, we ask whether file sharing networks will affect the survival or potential growth of European cinema. The steady decline in traditional film distribution channels for European productions—cinema theatres and direct sales or renting—is leading to the emergence of new distribution channels. And yet the results of the movie industry’s calls—including those voiced by its European players—for stronger legislation against these same distribution channels are making their way through Europe by means of enforcement tools like HADOPI and other graduated response programs. Our hypothesis is that this offensive runs the risk of condemning a potential open distribution network and commons business model at its birth. For this, we start by clarifying the emerging global P2P phenomenon; we then stipulate what we mean by European cinema, outline its peculiar traits, and contrast it with North American cinema. Finally, we compare the consumption of European film in theatres with the availability of seeds and leechers for European cinema in P2P networks.

Programagotchi: The Real Programmer Life Simulator
A one-week group project developed after classes at <Academia_de_Código_> with three other colleagues.
// The Idea
Inspired by well-know life simulation games such as Tamagotchi, we decided to emulate the daily-life of a real programmer, as he/she tries to survive by balancing the work activity required to earn money in contemporary society with the physiological needs of a regular human being: staying healthy, filling the stomach and getting some sleep.
All game…A one-week group project developed after classes at <Academia_de_Código_> with three other colleagues.
// The Idea
Inspired by well-know life simulation games such as Tamagotchi, we decided to emulate the daily-life of a real programmer, as he/she tries to survive by balancing the work activity required to earn money in contemporary society with the physiological needs of a regular human being: staying healthy, filling the stomach and getting some sleep.
All game actions are keyboard controlled: "q" for wealth actions; "w" for working actions; "e" for eating actions; "e" for sleeping actions". Upon accessing each action menu, the user can choose among a range of options by pressing the given number key.
// The Development
The only requirement for this project was to create a game with the tools given to us, with our recent found(or built) skills in java coding. After a few hours of brainstorming both the concept and the Classes diagram, we split tasks and began coding.
The project went through more than one redesign, resulting in a vastly different product from what was initially planned.
// My Role
My tasks were essentially related with developing the action menus: coming up with different kinds of options and giving a description of each. I also provided some Git hints to my fellow three other code cadets. Last but not the least: I helped the team to get together and hence to overcome the disputes that were threathening the launch of a minimum viable product.

// The idea
Based on a Hyperskill project (https://hyperskill.org/projects/62), this application was developed in Java and integrates the major features offered by the API. The API itself is structured on simple REST (Representational State Transfer) principles, commonly used for communication with web services.
As to the program, it is organized in terms of the MVC (Model-View-Controller), an architectural pattern for building an application. based on its separation in thre different parts in order to achieve a greater level of scalability and maintainability.

// The idea
The game starts by asking you the number of mines you want to spread throughout the field. The aim of the goal is to guess on which cells - located on a given coordinate x and a given coordinate y - has the program randomly placed the mines.
If you think that a given pair of coordinates x and y has no mine, you can enter its values followed by the option "free" in order to explore the surrounding terrain.
On the other hand, if the number of nearby mines indicated by the already revealed cells leads you to think that there is a mine underneath a specific cell that has not yet been uncovered, you can enter the same values of x and y followed by the option "mine".
The game ends when you accidentally fall upon a mine hidden in a given cell you thought was free (guess what? You lost!!) or when you guess the positions of all the mines within the field (Surprise, surprise: You won!!).

A web app developed in 24 hours for Academia de Código's hackathon that took place one week before the end of the bootcamp.
// The Idea
All the participating groups were given a randomly chosen song to develop a web app inspired by it in one day. Our group got "Everybody (Backstreet's Back)" by the BackStreet Boys. After watching the song's videoclip, we did a small brainstorming session in order to gather the most appealing ideas for an app remotely related with the clip. We opted for building an app based on a fantasy universe where vampires roam across the earth and they need blood to feed themselves. Hence the opportunity of connecting voluntary blood donors with vampires while also potentially making the bridge with the real world - ie, location of blood banks.
// The Development
We started by making a diagram of the core classes that we would need ("suckers" and "donors"), including their properties and methods. We took inspiration from Academia's own Javabank MVC architecture for the remaining classes and respective packages and adapted to our project's requirements. Given the short time frame, we opted for a front-end framework - Bootstrap -, from which we picked a template and customized its HTML and CSS. As an added feature, we included geolocation referencing via Google Maps API. The localization of the donors was specifically signaled so that vampires. Our biggest hurdle came when we tried to implement Thymeleaf as a Java template engine for serving HTML files. Despite some hiccups, we were able to successfully reach our goal and ended up in third place among a set of seven teams.
// My Role
I provided all the site's content, including the donors' profiles and their blood reviews by the vampires. I also gave some help in the implementation of agile methodologies (Scrum and Kanban).

A one-weekend group project developed after classes at <Academia_de_Código_>
//The Idea
Taking inspiration from the classic Bulletin Board System's (BBSs), we developed two command-line based applications: one for the client and another for the server. The aim of the project was to emulate the functioning of a BBS forum that took advantage of the networking and concurrency features of the Java programming language.

The aim of the project was to emulate the functioning of a BBS forum that took advantage of the networking and concurrency features of the Java programming language.
// The Development
Although we didn't have much time to develop the initial idea, we ended up with a project that not only fulfills the curriculum's requisites but also supports several command-line commands. The two final apps can thus be fully expanded in order to support additional features.
// My role
I suggested the initial idea for the project which was later on improved with the Master Coders' help. I also helped devising a solution for storing messages in files so that they can subsequently be accessed each time a new user enters an existing forum.
