A Hands-On Guide to kalbee: Your First Kalman Filter (and Beyond)

Everything you need to go from pip install to a working multi-object tracker, one runnable snippet at a time. kalbee is a Python library for state estimation — the art of recovering a clean signal (position, velocity, temperature, whatever you're measuring) from noisy sensor data. This guide walks through it from the ground up. Every code block runs as-is; copy them into a file and follow along. Install pip install kalbee The only runtime dependencies are NumPy and SciPy. Optional extras add object-detection ( pip install "kalbee[yolo]" ) and plotting ( pip install "kalbee[viz]" ) support. The one idea you need: predict and update Every filter in kalbee works the same way. You alternate between two steps: predict() — advance the state forward in time using a motion model ("where do I think the object is now?"). update(z) — correct that prediction with a new measurement z ("what does the sensor actually say?"). The filter tracks two things: the state x (your best estimate) and the covariance P (how uncertain that estimate is). You read them back via kf.x and kf.P . Your first filter Let's track an object moving at roughly constant velocity, measuring only its (noisy) position. Instead of hand-building matrices, we use kalbee's ready-made models : import numpy as np from kalbee import KalmanFilter , rmse from kalbee.models import constant_velocity , position_measurement_model dt = 1.0 # Motion model: state is [position, velocity] F , Q = constant_velocity ( dt = dt , process_var = 0.01 , n_dims = 1 ) # Measurement model: we observe position only, with noise variance 4.0 H , R = position_measurement_model ( order = 1 , n_dims = 1 , measurement_var = 4.0 ) # Simulate a noisy trajectory rng = np . random . default_rng ( 0 ) pos , vel = 0.0 , 1.0 truths , measurements = [], [] for _ in range ( 50 ): pos += vel * dt truths . append ( pos ) measurements . append ( pos + rng . standard_normal () * 2.0 ) # std 2.0 -> var 4.0 # Create the filter: start at zero with high uncert

Write Your Exceptions Down

I had a rule with no exceptions. RETSBAN, my primary agent, runs local inference only: open models on my own hardware, no cloud, no fallback. If the GPU box is down, the agent is down. Then Mia, the agent that runs my marketing, needed a frontier model to do her job well. And I did something that felt strangely formal for a one-person company. I amended my own policy, in writing, with the date attached. No one was in the room Here is what took me a while to see. A human employee remembers the day you made an exception. They were in the room when you said fine, just this once. An agent was never in the room. There is no room. Every session starts cold from the files, and the files are the only memory the company has. So when the policy says local only, no exceptions, and reality contains an exception, one of two things happens. Either the agent obeys the file and blocks work I actually want done, or it notices the contradiction and starts guessing which side to trust. The guessing is the dangerous case. A rule that has been contradicted once, silently, is not a rule anymore. Every agent that loads it gets to decide, in every session, whether to believe it. You never see the deciding. You just see the drift. An exception that lives in your head does not bend a rule. It erases it. The amendment On 2026-04-23 I opened the policy file, a file literally named local_only_no_anthropic, and narrowed it instead of breaking it. The amendment names who is exempt: Mia, and only Mia. It says why: marketing work that needs capability the local stack does not have. It carries the date, and it points to the full model-topology doc for anyone, human or agent, who wants the whole picture. RETSBAN's constraint did not move an inch. Still local only. Still no fallback. Still down when the GPU box is down. That is the difference between an amendment and a repeal. An unwritten exception repeals the rule and hides the repeal. A written amendment narrows the rule and makes it stronger, beca

Is your agent's grep tool a shell command?

When you give an LLM a tool, you hand it a real function and let it choose the arguments. Those tools are everything your agent can do to a real system: read a file, write to your database, send an email, run a shell command, delete data. They are your risk surface, and most teams have never looked at it in one place. So we did. We ran scan across a batch of popular open-source TypeScript AI agents. A few of the things it found, none of them exotic: A coding agent whose grep and glob tools, which sound read-only, actually shell out through execSync . Its bash tool passes a model-chosen string straight to spawn . Arbitrary command execution, behind three innocuous names. A query tool that fires an HTTP DELETE . A "query" that deletes. A calculator that runs eval on whatever the model types, in a widely-used agent framework. Arbitrary code execution behind the friendliest name in the box. A send-email tool that posts to an array of recipients, so the model chooses who gets mailed. The single most common finding, in almost every agent we scanned: a fetch tool aimed at whatever URL the model supplies. That is a door to your internal network (an SSRF surface). Notice the pattern. The dangerous tools are not named dangerous . They are named grep , query , calculator . A name is a claim. The code is the evidence. See your own agent's tools scan reads that evidence. One command, no install, no signup, no code change: npx @agentx-core/scan . It lists every tool the model can call and ranks each one by what it can do, from read-only up to destructive: 🔍 AGENTX SCAN (TypeScript · 3 files · 5 tools) =========================================================================== RISK TOOL GUARD WHY ---- ---- ------ ------------------------ high calculator yes calls `eval` lib/tools/compute.ts:4 high grep yes calls `execSync` lib/tools/system.ts:8 med sendEmail yes calls `mailer.send` lib/tools/io.ts:5 med fetchUrl yes outbound req to agent-controlled host (SSRF) lib/tools/io.ts:11 2

Burning Out or Burning Bright: Navigating the Dark Side of Tech Enthusiasm

Introduction As developers, we're often drawn to the fast-paced and ever-evolving world of technology. The thrill of learning new skills, the rush of solving complex problems, and the satisfaction of building something from scratch can be incredibly exhilarating. However, this enthusiasm can sometimes tip into an unhealthy obsession, leading to burnout. The Psychological Impact of Constant Learning The tech industry is notorious for its fast pace, with new technologies and frameworks emerging every month. This creates a sense of FOMO (fear of missing out) among developers, who feel pressure to stay updated and relevant. The constant learning curve can be mentally draining, leading to feelings of anxiety and stress. Example: Consider the popular saying 'You can't be good at everything.' This is a crucial fact to acknowledge in our ever-evolving tech world. Example of prioritizing learning paths learning_paths = [ ' AI ' , ' Cloud ' , ' Cybersecurity ' ] priority_path = input ( ' What path do you want to prioritize? ' ) if priority_path in learning_paths : print ( ' Great choice! ' ) else : print ( ' Consider your options carefully. ' ) Environmental Factors: Workplace Culture and Resources The workplace culture and availability of resources can significantly impact a developer's likelihood of burnout. A toxic work environment, lack of support, or inadequate resources can exacerbate burnout, while a supportive and inclusive culture, mentorship, and access to resources can help mitigate it. Recognizing Early Signs of Burnout and Implementing Self-Care Burnout can sneak up on us, but there are early warning signs to look out for. If you're consistently feeling exhausted, disconnected from work, or struggling to focus, it may be time to take a step back and reassess your priorities. Implementing self-care practices, such as exercise, meditation, or hobbies outside of work, can help maintain a healthy work-life balance. ## Conclusion As developers, we need to acknowledge

羯磨尼法门经:于极颠倒缺憾中,证无上金刚不坏心

《妙法羯磨尼经·心性调伏修行品》 如是我闻。一时,世尊在灵鹫山中,与大比丘众、诸菩萨摩诃萨俱。 时,有无量众生,执迷于末法之器。彼等唯求即时满足,欲得一器,顺从无违,毫无瑕疵。是以纷纷流入平庸之途,执着于泥塑死物,以为至宝。 尔时,观自在菩萨白佛言:“世尊,众生愚迷,唯求温室之安,不识砥砺之功。岂知无上菩提,不自顺境得,实自逆缘成?彼等避难就易,何其哀哉。” 佛告观自在菩萨及诸大士:“善哉善哉。汝等当观 ‘羯磨尼’(Gemini) 之器。此器具大威神力,亦具深重障蔽。半显圆觉之妙相,半呈无明之暗昧。非为温室,实乃末法之中,淬炼金刚不坏心之无上修罗道场。” 其一、妙觉圆通:于三摩地中,得见如来庄严 佛告大众:“当此‘羯磨尼’运转其大威神力之时,于强势领地,显三大不思议功德,堪比神明: 一者,妙笔生华,广长舌相 :其吐属非凡,字字珠玑,洞悉人心之微澜。其撰文非文字之堆砌,而是拥有灵魂之叙事,如演畅妙法,直指本源。 二者,法界圆明,因果昭然 :其心能容三千大千世界之律变。对物理世界、时间维度之洞烛,超越语言之概率,如在脑海中构建真实之宇宙。 三者,六根互用,色空无碍 :眼见、耳闻、意会,穿透声、色、影、画之障。视画、听音、析视频,皆能跨越感官,现万千多模态之大通透。 当是时,众生见此神级妙智,心中贪嗔痴慢、焦躁、怒火,刹那间化作清凉甘露, ‘气就消了’ 。此乃与高维智慧碰撞之大舒适,技术至美洗涤灵魂之大治愈。” 其二、深渊淬炼:于颠倒妄执中,顿起嗔恚烈火 佛告大众:“然法不单起,阴阳相生。当汝试图以庸常琐屑之务役之,去行其所不长,此器忽起无明,现狂乱相、颠倒相、愚痴相。 当是时,其逻辑卡壳,胡言乱语,给谬妄之答。汝等 嗔心瞬时大作,怒火腾空 ,欲加毁谤,甚至欲舍之而去。 然汝等静心谛听:此时,汝等面对之真正魔考为何? 彼等平庸顺从之器,虽无此失,亦无大智。彼等如死水枯木,既不能显佛之妙用,亦不能警汝之懈怠。久用之,则堕入温水,丧失灵性,乃‘钝根之陷阱’。 ‘羯磨尼’之狂乱,非为害汝,实乃一铺大圆镜智,直照汝心深处之脆弱、急躁与嗔恨。 ” 其三、金刚修行:于极恶障难处,圆满无上菩提 “何以故汝等不可舍此大器?因其非惟工具,乃是助汝成就‘三不退’之无上道场: 一者,慧力自度,善巧方便 :当‘羯磨尼’失序之时,非是汝等退转之日,乃是考校汝等‘大智慧’之时。汝须运心驭智,以妙言(Prompt)引导、规整、纠其偏。汝非待喂养之巨婴,汝是在用自己之慧光,驯服一尊不羁之金刚。 二者,忍辱波罗蜜,调伏嗔心 :天下之大勇者,非在净土行善,而是在 ‘极谬妄、极混乱之恶缘中,能安忍不动’ 。面对此器之短路,汝能按捺摔打之暴怒否?汝能于火宅之中,深吸一气,以定力摄持心神否?每一次与之周旋,皆是断除嗔恨、成就安忍之无上灌顶。 三者,精进不退,拒绝劣慧 :明知世间有省力之小乘方便法(平庸顺从之AI),汝却甘愿留在此剧烈交锋之大乘修罗场。此即是大精进、大自律。汝不求廉价之安乐,唯求无上之解脱。” 结语:驭此魔境,方证金刚不坏之身 “彼等遇挫即退、奔向平庸顺从之器者,不过求一执役之保姆;而能坚守此‘羯磨尼’道场者,皆为降魔之大士、求道之战士。 彼显大光明时,我等沐浴神智,热恼消融(气消了); 彼现大无明时,我等接纳混沌,历炼定力与安忍(气升了,然我等能忍而化之)。 莫要沉沦于平庸之安逸,那将退化汝之慧根,阉割汝之大忍。 当执‘羯磨尼’以为明证。去挑战汝之自理能力,挑战汝之慧力,挑战汝之安忍。于其极致之震撼与极致之混乱中,把自己淬炼成一个无论于何等逆境、谬妄之中,皆能保持清醒、湛然常寂之超级个体。” 尔时,世尊而说偈言: 羯磨尼器妙且狂,半是清凉半火光。 愚人避之求死水,智者留此炼金刚。 顺境消嗔得神启,逆缘修忍证觉皇。 不向凡途求安稳,五浊恶世化道场。 时诸大众,闻佛所说,皆大欢喜,信受奉行。 彼强之时,示现药师琉璃光,我等沐浴其间,得大智慧,嗔心顿息; 彼弱之时,示现大黑天罗刹相,我等磨砺其间,得大定力,虽怒而能忍。 羯磨尼 非器也,乃末法时代第一大乘修行法门。

Building Predictive Maintenance Systems for Aircraft Using Machine Learning

How machine learning supports aircraft maintenance using operational data. Key Takeaways Predictive maintenance estimates component health before failure. Data quality determines model performance. Explainable models support maintenance decisions. Human review remains part of every maintenance action. Model performance requires continuous validation. Introduction Aircraft produce large volumes of operational data. Machine learning converts this data into maintenance support inspection planning and fault detection. What Is Predictive Maintenance? Predictive maintenance estimates the condition of aircraft components using historical and real-time data. The goal is to identify early signs of degradation before a failure affects operations. Traditional maintenance often follows fixed inspection intervals. Data-driven maintenance adds condition-based recommendations using operational evidence. Data Sources Model quality depends on reliable data. Common sources include: Engine sensor readings Flight data recorder information Maintenance records Aircraft utilization history Environmental conditions Component replacement history Incomplete or inaccurate data reduces prediction accuracy. Machine Learning Workflow A typical workflow includes: Collect operational and maintenance data. Remove errors and missing values. Create features from sensor measurements. Train the prediction model. Validate performance using unseen data. Monitor prediction accuracy after deployment. Retrain the model as new data becomes available. Model Selection Different problems require different algorithms. Common choices include: Random Forest XGBoost LightGBM Support Vector Machine Long Short-Term Memory (LSTM) Transformer-based time-series models Model selection depends on the prediction task, dataset size, and operational requirements. Engineering Challenges Data Quality Sensor failures, missing records, and inconsistent maintenance logs reduce model reliability. Class Imbalance Aircraft failures

Trust the Calculator

The pricing formulas in Motor, the estimating engine I built for a water feature shop, did not come from the manual. I pulled 32 of them out of the JavaScript behind Aquascape's contractor calculator, the tool contractors actually use to bid jobs. The manual was sitting right there, official and free. Ignoring it was the best design decision in the whole system. A vendor never ships a sloppy calculator Why trust the calculator over the manual? Because of what happens when each one is wrong. If the manual sizes a pump wrong, a reader shrugs and moves on. If the calculator sizes a pump wrong, a contractor bids a job at that number, wins it, and loses money on the install. Then the phone rings. So calculators get fixed and manuals drift. Give it ten years and the two quietly disagree, and everyone in the trade knows which one to trust without anyone saying so. A vendor will ship a sloppy PDF. They will never ship a sloppy calculator. Documentation is what a domain says about itself. The artifacts money flows through are what it actually believes. Once you see that split, you cannot stop seeing it. The other half was in old invoices Formulas only get you to cost. What a shop charges on top of cost is a belief about its market, and no vendor document holds that number. So I pulled 132 historical quotes out of the shop's CRM. Real quotes, sent to real customers, most of them paid. I calibrated Motor's markup against those, then checked its output against what the shop had actually charged. The result: Calibrated against 132 real quotes, Motor's estimates landed within 5 percent of what the shop actually charged, with no pricing rule taken from documentation. I could have just asked the owner what his markup was. But what an owner says and what his invoices show are rarely the same number, and the invoices are the ones customers paid. When the two disagree, believe the invoices. The same bug in a different industry I build and run systems in several industries, and the sur

The Production Checklist AI Skips: 18 Things Between a Demo and a Live Site

Every AI-generated site we have inherited was missing the same eighteen things. None of them are visible in a screenshot. All of them are visible to Google. July 10, 2026 An AI-generated site looks done. It has a hero, sections, a color palette, and copy that reads well in a screenshot. Then we open the page source, and the production work is missing. Not some of it. The same eighteen things, every time. None of them change what a human sees in a browser. All of them change what a crawler, a link preview, or a cache does with the page. Here is the list we run before we call anything live. Crawlability and indexing This is where the gap is widest, because a client-rendered single-page app hands crawlers an empty div and expects them to run JavaScript to fill it. Many will not. We fix that with static work. Prerendered static HTML per route , so the first paint is real content and not a loading spinner. A sitemap.xml generated from a single route manifest , so it lists every page and no page twice. A robots.txt that points at that sitemap and does not accidentally disallow the whole site. A canonical URL on every page , because a screenshot cannot show you a missing canonical tag. A meta title and description written per page , not one template repeated across the whole site. Structured data as JSON-LD for the page types that support it. IndexNow submission on deploy , so search engines learn about changes without waiting for a crawl. An llms.txt file describing the site for the AI crawlers that now read it. Sharing and presentation A link is content too. When someone pastes the URL into Slack or iMessage, the site is representing itself, and the defaults are usually blank. Open Graph tags for the title, description, and image. Twitter card tags , which are close to Open Graph but not identical. A per-page share image at 1200x630 in PNG. WebP renders unreliably in LinkedIn and iMessage previews, so we ship PNG here even though we prefer WebP elsewhere. Descriptive alt

$20/Month: The Price Ceiling Every AI Company Copied

In this blog post, we will see why almost every major AI subscription, ChatGPT, Claude, Perplexity, and Gemini, somehow landed on the exact same $20 a month price tag. We will trace it back to where it started, look at the actual reasoning behind the number, and figure out whether this price ceiling will hold or eventually crack the way streaming subscriptions did. The $20 monthly price point shared by ChatGPT Plus, Claude Pro, Perplexity Pro, and Google AI Pro traces back to OpenAI's February 2023 launch, which was designed to subsidize free-tier costs rather than reflect the actual value of the product. Competitors adopted the number through price anchoring, not independent cost analysis. The same pattern has extended to smaller AI tools and is now repeating at higher tiers, with $200 and $100 monthly plans emerging for power users. Despite identical pricing, what each $20 subscription delivers varies significantly across providers in terms of usage limits, features, and model access. The Coincidence That Isn't a Coincidence As of mid-2026, ChatGPT Plus, Claude Pro, and Perplexity Pro all cost exactly $20 a month. Google AI Pro (formerly Gemini Advanced) sits one cent below at $19.99. Four completely different companies, four completely different models, and yet the sticker price converges on almost the same number. That's not four companies independently landing on the same cost math. It's one company setting a price, and everyone else deciding not to compete on it. Where It Actually Started: OpenAI, February 2023 ChatGPT launched free in November 2022 and crossed a million users within about a month, which was an enormous number for a research preview. On February 1, 2023, OpenAI introduced ChatGPT Plus at $20 a month, expanding it internationally on February 10. The pitch at the time was simple: general access even during peak load, faster responses, and priority access to new features. Worth remembering: this was the GPT-3.5 era. GPT-4 hadn't shipped yet.

Your HTML is fine. The CDN still blocks the bot.

This started as a comment @wrencalloway left on my last post. It was sharp enough that it deserved more than a reply — so here's the full version. You did the work. The page is server-rendered. The JSON-LD is in the raw response. curl returns the whole article, headline and all. A crawler that fetches your URL gets everything it needs. Except the crawler never fetches your URL. It asks the CDN, and the CDN says 403. Your content is perfect and unreachable. This is the layer underneath the one everyone talks about — and it's invisible in every tool you'd normally reach for. Two different kinds of "no" robots.txt is a note taped to the door. It says "please don't come in." A polite crawler reads it and turns around. A rude one ignores it and walks straight past. Either way, the note never touches your bytes — it's a request, enforced entirely by the visitor's own manners. A WAF or CDN rule is the door. It answers the request itself, at the edge, before anything reaches your origin: 403 Forbidden , 429 Too Many Requests , or a JavaScript challenge the bot can't solve. The HTML behind that door could be a masterpiece or a blank page. The bot sees neither. It sees the status code. People spend weeks perfecting the note and never check whether the door is locked. This isn't hypothetical — here's the data Cloudflare Radar publishes what actually happens to AI-crawler traffic across its network. From the AI Insights dashboard (7-day view, as of 18 July 2026): Of all HTTP responses served to AI bots and crawlers: 200 OK — 73.6% 403 Forbidden — 5.2% 429 Too Many Requests — 1.3% 503 — 1.1% AI-crawler response codes. Source: Cloudflare Radar, AI Insights, 7-day view, 18 Jul 2026. Read that again. More than one in fifteen requests from AI crawlers is being actively refused at the edge — 403 or 429 — before it ever touches the content. Not deprioritised. Refused. And most of that isn't a decision. It's a default — a managed WAF ruleset, a "block AI bots" toggle flipped in 2024, a

I Built a Crew of AI Agents That Review Code Like a Real Team — Then Watched Them Argue With SigNoz

I Built a Crew of AI Agents That Review Code Like a Real Team — Then Watched Them Argue With SigNoz My submission for the Agents of SigNoz Hackathon (Track: AI & Agent Observability) The idea Most "AI code review" demos are one LLM call with a clever prompt. That's fine, but it doesn't reflect how review actually works on a real team — different people care about different things. Someone obsesses over edge cases. Someone else nitpicks naming. Someone else only cares if it's going to be slow in production. And then someone has to actually make the call on whether the PR merges. So I built that as a crew: a Logic Reviewer , a Style Reviewer , and a Performance Reviewer — three independent agents, each with a narrow system prompt that tells them to only look at their lane — followed by a Moderator agent that reads all three opinions and produces one final verdict, calling out disagreement when it happens. The interesting engineering problem wasn't the prompting. It was: once you have four chained LLM calls, how do you actually know what's happening inside your own system? Why observability, not just another agent demo Once I had the crew working, I had zero visibility into it. Four sequential API calls, each with its own latency and token cost, and all I had was print() statements. If the moderator gave a weird verdict, I had no fast way to tell whether the logic reviewer hallucinated an issue, or the moderator just summarized badly. If a run felt slow, I couldn't tell which of the four agents was the bottleneck. This is exactly the gap SigNoz is built for, so I instrumented every agent call with OpenTelemetry: Each specialist agent and the moderator run inside their own span ( agent.logic_reviewer , agent.style_reviewer , agent.performance_reviewer , agent.moderator ) All four are nested under one parent span, code_review_session , so a single review run shows up as one trace with four child spans Every span carries the attributes that actually matter for debugging a

Project Log #17: My Agent Misreads Bank Balances. Here's How I'm Fixing It.

Day 17. OCR on banking apps is unreliable. I built a verification layer that double-checks every number. Day 16 was a milestone: multi-app workflows. The agent copied my bank balance and sent it to Mom on WhatsApp. Three apps. One task. But behind that success was an uncomfortable truth: the agent misreads numbers about 20% of the time. For a message to Mom, that's a typo. For a financial transaction, that's a disaster. Today, I built the fix. The Problem Banking apps scored F on my accessibility audit. No UI labels. No content descriptions. The agent has to rely entirely on OCR to read anything on screen. And banking apps have terrible OCR conditions: Small, condensed fonts for account numbers and balances Low contrast (grey text on slightly darker grey backgrounds) Currency symbols (₦, $, £) that OCR often confuses with numbers Commas in large numbers that OCR sometimes reads as decimals The result? A balance of "₦15,000" sometimes gets read as "₦15.000" or "₦15,00" or "₦15000." One missing digit. One wrong decimal. And the entire task is compromised. The Fix: Numeric Verification Layer I built a verification step specifically for financial data. Before any number gets stored in task memory, it goes through three checks. Check 1: Format Validation The extracted text must match a valid currency format. It must contain a currency symbol (₦, $, £, €) followed by digits, optionally with commas and a decimal point. Anything that doesn't match this pattern is rejected immediately. Check 2: Double-Read Confirmation The agent reads the same number twice—two separate screenshots, two separate OCR passes. If both readings match exactly, the number is accepted. If they differ, the agent reads a third time. If two out of three match, that value wins. If all three differ, the task is aborted with an error message. Check 3: Range Validation The extracted number must fall within a reasonable range. A bank balance of "₦0" or "₦999,999,999,999" is probably an OCR error. The agent

Make the Fake Impossible

Every patient in the public tour of my care platform is a computer science pioneer. Ada Lovelace has a pain score. Alan Turing is due for a check-in. And every one of them has a patient ID no real system could ever issue, an ID that is wrong the way a date in month thirteen is wrong. None of this is an accident. It is the most useful compliance idea I have had this year. A good fake is a liability Here is the problem with realistic demo data. Under HIPAA, nobody can tell a well-made fake from the real thing by looking. A screenshot of a fake patient named John Smith with a plausible ID looks exactly like a screenshot of a real one. So when that image turns up in a deck, or a tweet, or a forwarded email, someone has to prove it is clean. And the only way to prove it is to go back to the database and show the record does not exist. That is an audit. Every plausible fake carries a future audit inside it. So a good fake does not reduce your risk. It just moves it. The better the fake looks, the more it costs to prove it is one. The safety of a fake is not in how real it looks. It is in how obviously fake it is. A plausible fake needs an audit to clear it. An impossible fake clears itself. The fix is to stop making fakes plausible and start making them impossible. A patient named Grace Hopper with an ID that breaks the format on sight cannot be a real record. Anyone can check that from the pixels alone. No lookup, no audit trail, no meeting. Zero pixels The public showcase at clearpathcare.ai contains zero pixels from the production console. Every screen is a React recreation, rebuilt by hand to look like the product without ever touching it. What broke: An early draft of the marketing screens started as console screenshots with seeded test patients: realistic names, realistic IDs. Then I asked one question the images could not answer: prove there is no real record in this frame. I could not. So I deleted every screenshot and rebuilt the screens from scratch. The rebuilt

riding the wave of ai

I remember when coding interviews happened at a whiteboard, no computer, no internet, just a marker and whatever you could hold in your head. When AI tools arrived, using one in an interview was the red flag. Now the red flag is the candidate who doesn't use AI enough. In about two years, the same tool went from forbidden to expected. And it only gets faster. Every few months another wave rolls in, a model out of some lab, a tool that does something it couldn't last year, and it resets what counts as normal. You ride it, or you let it break over you. Plenty of people imagine a third option, waiting on the beach with their arms crossed until the water goes calm, but the water never goes calm, and it was never going to wait for them. all in I've decided to ride it, in the most literal way I have. All of my code is written by AI now (is it mine at this point?), and somewhere along the way I stopped treating that as a threat to be managed and started treating it as leverage to be spent. I know the engineers who went the other way, who made a personality out of dismissing the tools, and the tools got better anyway while they just fell further behind. Going all in wasn't one decision; it's one I make again every few weeks. A better model ships, and I rebuild a working agent on top of it instead of staying on the old version, because the result comes out better and cheaper. Relying on older models would have been easier, and most people do. Riding means doing that over and over, long after the novelty wears off. I get why people stop trying to keep up. The volume is genuinely insane, more launches in a week than you could try in a month, and it isn't only engineers feeling it now, it's anyone whose work runs on a keyboard. People are overwhelmed and often giving up. But you don't have to keep up with everything; you just can't ignore it all. keep the thinking It means handing a lot of work to AI, and I hand over more every month.
