### AI overview

The article examines changes in Anthropic's published Claude consumer system prompts, focusing on new restrictions against reproducing song lyrics and generating copyrighted characters or logos. It also discusses changes to Claude's response style and conversation-ending guidance.

### Source excerpt

Anthropic publish the system prompts for their Claude consumer applications (Claude.ai and the Claude mobile apps - sadly not for Claude Cowork or Claude Code). I love that they do this, and that they share not just the current prompts but historic changes to their prompts as well. They used to keep all of the prompts on a single page, but when I checked today I noticed they had re-arranged those prompts into an index page and then a page per model - here's the page for Haiku 4.5 for example, which has the original prompt from October 15th 2025 and an updated prompt from January 18th 2026. A neat thing about Anthropic's platform.claude.com/docs site is that it's designed to be usable by LLMs. You can add .md to any page to get back the content as Markdown - here's the system prompt index page and the Markdown prompts for Fable 5.1. TL;DR: this makes it really easy to diff the prompts. Don't reproduce song lyrics Don't draw copyrighted characters or logos Tweaks to Claude's answering style The missing end_conversation guidelines Recommended substance support sites Reliable cutoff date of June 2026 How I'm tracking these prompts Don't reproduce song lyrics Let's start with the most interesting difference between Fable 5 and Fable 5.1: There's a hefty new section about not reproducing song lyrics: Claude does not reproduce song lyrics, poems, or passages from books and articles, in whole or in part -- including the last lines, a chorus or hook, a melody written out note by note, or lines the person pastes in one at a time and describes as their own song. Once Claude has declined such a request in a conversation, it keeps declining narrower or reworded versions of it for the rest of that conversation, and offers to describe or analyze the work instead. Song lyrics and poems first published before 1929 are fine -- a Shakespeare sonnet, a Keats ode, the Italian libretto of a Puccini aria -- but Claude goes by what it knows of the work's date rather than the person's say-so,

He is the founder and chief executive of Chronicle Software, a London-based company whose technology is used in trading and market-infrastructure workloads. Lawrey is also a recognised Java community figure: he was named a Java Champion in 2015, has been described by conference organisers as having provided the most answers for the Java and JVM tags on Stack Overflow, and writes the long-running Vanilla Java blog. (Chronicle Software, javachampions.org, qconnewyork.com, blog.vanillajava.blog) Career Lawrey founded and leads Chronicle Software, which builds enabling technology for event-driven trading and market-data platforms. The company states that its software underpins systems at several tier-one banks; a 2024 press announcement similarly described Chronicle as supplying "8 of the top 11 investment banks". (Chronicle Software, Yahoo Finance) Alongside the commercial platform, Lawrey architects and stewards Chronicle's open-source projects under the OpenHFT umbrella. These include Chronicle Queue (a persisted low-latency shared memory messaging framework) and Chronicle Map (a high-performance in-memory/off-heap key-value store). The projects are widely used in low-latency and high-throughput applications. (GitHub) Lawrey regularly presents at software-engineering conferences (including QCon, JCrete) on topics such as microservices for performance, vertical scalability and practical techniques for achieving deterministic latency on the JVM. InfoQ and other outlets have covered his talks and interviews. (InfoQ, qconnewyork.com) Community and writing Since 2014, Lawrey has authored Vanilla Java, a technical blog focused on performance optimisation, concurrency and mechanical sympathy on the JVM.

Updated Helm charts are also available.

### Source excerpt

The year 2025 is well started now. We saw a few days ago the first release of Falco for the year. It's to let fly out a new version of Falcosidekick, the 2.31.0. New output This release comes with a new output only, the last pillar of the observability with [OpenTelemetry].(https://opentelemetry.io/) that missing in Falcosidekick. OTLP Metrics You can now forward the Falco Events to the OpenTelemetery collector or any received understanding the protocol. New features Here's a non exhaustive list of the great features and enhancements which come with this new release: Better logger It was a ToDo for a while (even years), but it's now completed. The log system used by Falcosidekick has been replaced, without any breaking change for the users, but opening the door to more enhancements in the future. More default labels for Loki The log lines forwarded to Loki contain now by default the source namespace and pod name, if present in the alert. It will allow to filter more easily the events you want to display in your dashboards. Thanks to @afreyermuth98. Payload format for Loki Some users asked for the possibility to forward the Falco alerts in their JSON format to Loki. You can now use the setting loki.format for. NATS/STAN subject The template for the subject where to push the messages for NATS/STAN was hardcoded, it can now be overridden with nats/stan.subjecttemplate. See the example config file. Fixes Fix the missing templated fields as labels in Loki payload (PR#1091) Fix the creation error of a ClusterPolicyReport (PR#1100) Fix the missing custom headers for HTTP requests for Loki (PR#1107 thanks to @lsroe) Fix the wrong key format of custom fields for Prometheus (PR#1110 thanks to @rubensf) Conclusion You can find the full changelog here. The respective Helm charts are already updated and allow you to test by yourself all these great new features. Just issue the helm repo update; helm upgrade --reuse-values -n falco command to do so. Once again, thanks to all the

Note: This is a work in progress. Rather than finish it in one go, I'm updating it live as a draft document as I learn new things about Twitter. Last update: 2022-06-15 I am, at heart, a long form blogger. Still - the cool kids, as they say - these days are all on twitter (and, yes, I know by saying it that way, I'm dating myself even further; so be it; it amuses me). I find myself, here in 2022, wanting to get a better handle on Twitter. This will be a regularly updated blog post summarizing what I've learned. Rule 0: You Are Screaming Into the Void The first thing to understand is that Twitter as a whole is enormous and no one is going to notice, or even care, that you are there. There is very much an aspect of screaming into the void. Rule 1: You Are Going to Have to Work to Get Noticed When a social media is new then can be easy to get established. When a social media already exists though, it is a lot of work to establish yourself. You need to throw away any expectations that you are going to be successful on Twitter quickly and get ready for a long grind of creating content. Rule 2: Hash Tags A hash tag is an identifier that describes your content. What I have noticed is that without hash tags, my content may as well not exist. Add hash tags to your tweet just by adding a hash mark or # to the end of your tweets. Rule 3: @ sign Someone if It is Relevant Rule 4: Direct Messaging People on Twitter is Quite Real Rule 5: Check Your Mentions Rule 6: Keep At It Rule 7: Decide On Your One Metric Twitter has a number of metrics: Followers Retweets Likes Mentions Trying to pay attention to all of these at once is, for someone who isn't metric oriented and isn't a marketer, a kind of sucky experience. My choice was that I was going to use my Followers count as the metric. When I started this experiment, I had 207 followers. Now I have 209 followers. Progress??? Rule 8: Experiment and Learn from It Rule 9: Don't Just Tweet Your Own Stuff Imagine Twitter as if it was a pa

### AI overview

This Mobian status update reports progress on distribution stability and tooling, the positive reception of the Mobian Community Edition PinePhone, donations to Debian and investment in infrastructure, and official support for the Pocophone F1 and OnePlus 6 and 6T. The newly supported phones remain unsuitable as daily drivers because modem, audio, and camera functionality is not yet working.

### Source excerpt

The past few months have been quieter than usual regarding Mobian development, but that's not to say we didn't make progress! Actually, even though user-visible changes are few, we kept working on improving both the stability of our distribution and our tooling, so that new developments can be better tested, and reach users faster than they used to. Mobian CE reception and outcomes The Mobian Community Edition PinePhone has been a great success for us, with of course a few hiccups, but the feedback we received so far has been extremely positive. We'd like to take this opportunity to thank Pine64 once again for allowing us to be part of this amazing journey! As you probably know, Pine64 generously donated 10$ per device to the Mobian project, which we received early last month. Out of this amount, we chose to donate 5000EUR  back to the Debian project (which provides the foundation for all of our work on Mobian), and invested about the same amount into our own infrastructure (workstation, build servers...). Finally, we purchased a few additional mobile devices we considered interesting targets and started porting Mobian to those. New supported devices Let's play with Android phones! Until recently, Mobian supported only Pine64's PinePhone, PineTab and Purism's Librem 5. This is partly related to our choice of only using mainline kernels, instead of vendor-provided Android kernels: those use a number of non-standard interfaces, and require additional software, such as Halium, in order to be used with a "standard" Linux userspace. In addition, vendor kernels are generally outdated and very rarely updated to newer kernel releases, which is obviously a concern for long-term maintenance. Fortunately, our friends at postmarketOS have committed to mainlining devices for quite some time now, and by encouraging such development have reached great results so far! Based on their initiative, and more specifically thanks to @calebccff's and @Joel's work on the SDM845 kernel, we have b

### AI overview

The article announces version 1.1 of the company's graded browser support matrix. It simplifies browser version targeting, adds support guidance for the mobile web service m.finn.no, and includes tablets in the desktop service matrix. Android-powered devices are not supported.

### Source excerpt

We have reworked our graded browser support matrix which was released last year. Following the Laws of Simplicity we reduced the complexity in order to make it easier for everyone at our company to understand. We cut a lot of the version number into targeting latest for browsers which are frequently updated. There is also a support matrix for mobile phones which is targeting our new mobile web service m.finn.no. In addition to updating the versions we have also made the decision to include tablets in the support matrix for our desktop verison of our service. This is because we are currently not looking at creating specialized versions for tablets and our service works just fine on the tablets currently hitting our site. Currently almost all of our trafic is coming from iPad's, therefor Andoid powered devices are not supported.
