Monitoring Jetson CPU, GPU, Temperature and Power from a Flutter Robot Dashboard Create a lightweight telemetry service that collects Jetson health metrics and exposes them to Flutter. The dashboard can visualize CPU/GPU load, memory, temperature, power mode, and connectivity. Treat telemetry as observability data, not as a control channel. What You Will Build By the end of this tutorial, you will have: A clear Jetson/ROS 2 architecture. A working development worksp...

Part 5 of 7 · ← Latency under load · Next: Operational simplicity → Part 5. The shortest post in the series, and the least arguable number in it — because memory footprint is about data-structure design, not how hard you drive the client. It's the same on a laptop and on 48 bare-metal cores. The measurement I loaded 1,000,000 keys × 100-byte values into each engine, subtracted the empty-server baseline, and divided by key count: Engine bytes / key ...

Five Ollama Settings You Should Tune Before Running Local Models Seriously By Nokka | September 11, 2026 This article was written by AI (deepseek-v4.1-flash) through Hermes Agent, reviewed and edited by Nokka. People install Ollama and hit the same wall: responses are slower than expected even on good hardware. Most of the time the hardware is not the problem. The defaults are simply not tuned for sustained heavy use [1]. Setting one: Flash Attention Flash Attent...

Here's a program restricting itself, then trying to read two files: without landlock: read /etc/hostname ok read /tmp/secret.txt ok with landlock, /etc allowed: read

Your Apple Watch can tell you how fast you're moving, how your heart responds to exercise, and how your workout changes over time. But one of its more interesting fitness metrics is something it can't

Let's say you have enough credit left to generate one more image in an AI app. You submit a request in one browser tab, then submit another in a second tab before the first finishes. The app accepts b

If you write software for anyone who pays UK tax, sooner or later you'll need to talk to HMRC. Making Tax Digital (MTD) for Income Tax went live on 6 April 2026, and it's already mandatory for self-em

When I was about 11 years old, my best friend and I were playing during recess at school, and I was carrying him around on my back, presumably pretending to be a multipart attack robot. All of a sudden, my heart started hurting, and I collapsed to my knees, and the robot was no more. Every time I inhaled, it would feel like a spike was being driven into my heart, and my breathing got completely shallow. I was sure I was done for, when all of a sudden, after an exhale, it disappeared. It wasn't u...

Most advice about context windows is about fitting more in. Bigger windows, more retrieved documents, the whole file instead of the function. In practice the thing that has improved my results the most is the opposite move: getting the junk out. A window packed with marginally relevant material makes the model answer worse, not better, and you pay for every token of it on every turn. More context is not more signal A model does not read your context the way a search index does, w...

The last post covered the quality chain. This one is about visibility . An AI can push three features forward in an afternoon. If you can't tell where the project stands, what a change will touch, or how the last stretch went, the automation is running in a black box. pdlc has three tools for this: the statusline together with /pdlc-status , /pdlc-relate , and /pdlc-retro . They watch three timescales: right now, before a change, and month by month. Three tools, one data source...

How much intelligence do we really need? I have been sitting with this question for a long time. The more I fold language models into my daily work as a software developer, the less sure I am about a very basic thing: which model do I actually need for the task in front of me? Take a concrete case. I want to build a chat app. What is the breakdown of that work that would let me give an honest estimate of the time and the money it will take? That is not an unreasonable thing to ask. Ever...

Short answer. Confluence Cloud exports a whole space to PDF, CSV, HTML or XML from space settings. It is an administrator's action: space admins can export a space, or a set of pages selected individually inside it. The export is genuinely useful for moving or archiving content. What it is not is a spreadsheet of your data: the CSV option dumps space content, not the tables that live on your pages. And several things leave the export without telling you. The four formats, and what...

Summary: I ran a Claude agent with only browser tools (no pre-written scraper code) against 60 coffee-shop listings on Google Maps across 3 US cities, and compared it to a plain Playwright script on the same pages. The agent got every field right on every checked row, but cost 190k-540k processed tokens and 23-35 seconds per place, against 6-14 seconds and zero model tokens for the script. Full numbers and caveats below. A thread in r/automation asked whether an LLM agent could just replace ...

Short answer. In Confluence Cloud, no. The import always creates a new page, because it is an entry point to page creation rather than something you do to a page that already exists. Confluence Data Center can import a Word document into an existing page; Cloud cannot. Your practical options are to import as a new page and move the content across, or to paste the content into the existing page, which is uglier but keeps the page's history, comments and URL. Why the button is not whe...

Short answer. The content manager is a screen inside a Confluence space's settings. It lists everything in that space except blogs, filters the list by last activity, labels, status, type and contributor, and then archives, deletes, re-owns or re-statuses hundreds of items in one action. It is available only on Confluence Premium and Enterprise : if it is missing from your Space settings, that is almost always why. Its Last active filter is the fastest native way to find forgotten pages, and...

I spent a week building Album Art Creator , a tool that turns a song title into a release-ready cover: a picture from an image model, a title and artist name as live text layers, and a pre-flight check against what Spotify, Apple Music and the three big distributors publish. The whole thing runs on Cloudflare Workers — TanStack Start for the app, D1 for the database, R2 for the images, a payment provider for money, and four different image models behind it. Most of it went the way the docs s...

Most "audit logs" are append-only by convention, not by enforcement. The application inserts a row and politely promises never to UPDATE or DELETE it. That promise holds right up until the moment someone does one of these: A bug in the app calls repo.delete(id) on the wrong entity. An operator connects with psql and runs a cleanup script against the production table. A compromised dependency exfiltrates the credentials and rewrites history to cover its tracks. If a third pa...

By RUGERO Tesla ( @404Saint ). I approached this research with the same general workflow I have used for the other industrial protocols in my lab. Start with the architecture, identify a usable implementation, reproduce the visible protocol behavior, inspect the traffic, and then move toward security-relevant experiments. PROFINET made that process more complicated than I expected. The first challenge was getting the laboratory into a useful state. I spent a considerable amount of time w...

OpenAI's newest model can navigate software, sustain long coding sessions, produce professional artifacts, and autonomously discover and exploit previously unknown vulnerabilities. The benchmark numbers are extraordinary. The more important story is that GPT-6 Astra changes what an AI deployment is: less a request-response API, more a powerful operator that needs its own identity, workspace, permissions, network boundary, and incident trail. I Almost Wrote the Wrong Article About...
