Show HN: Lean bulk, cut, body recomp. Calculate maintenance calories A very simple idea: when you eat more than your maintenance calories, you gain weight; when you eat less than your maintenance calories, you lose weight.<p>By using an algorithm, we can accurately figure out your maintenance calories more accurately than traditional regression based formulas like katch mc ardle.<p>It&#x27;s way more accurate than calorie burn tracking devices like fitness bands and watches. (garmin&#x2F;apple watch&#x2F;whoop etc...)<p>Traditionally, people often use static TDEE calculators which often over or underestimate for some by 100s calories.<p>Chatgpt and TDEE calculators like Calculator.net or TDEECalculator.net use the same formulas, so they share the same limitation<p>If a beginner asks ChatGPT, &quot;What are my maintenance calories?&quot;, ChatGPT can give them a number. But ask how it arrived at that number, and it will usually explain that it used a formula like Katch McArdle, Harris Benedict, or Mifflin St Jeor to calculate BMR, then layered activity on top using an activity factor, PAL, or MET tables.<p>Dig deeper and those formulas come from statistical regressions based on averages from past populations. That means maintenance calories calculated this way can be off by hundreds of calories.<p>MacroCodex uses your calorie intake and weight data to figure out maintenance calories specific to your body, not the population average.<p>It usually reaches good accuracy after about 3 weeks, or 21 days of calorie and weight logging.<p>This app is completely free, no paywall, no subscription and no ads. (works offline)<p>Most people start seeing weight gain or loss within 5 weeks.<p>We&#x27;ve reached 13,000+ users. Full support is provided if you experience any issue, most issues are resolved under 24 hours.

Show HN: HN Game Stories – mini-documentary of games that hit the front page Hi all, This is coolwulf and I have been working on a project. The idea is to generate video content on popular Hacker News gaming stories. So far I just started this idea and will continue contributing to the content.

Show HN: TLA+ Process Studio Disclaimer: This was made with LLMs.<p>I made this tool to help understand large business processes that can be modelled as a single state machine.<p>The core loop of this is to enable to walk stakeholders through discussing each step, adding comments, and reiterating with an LLM of their choice to generate the TLA+ syntax on the left.<p>Users can click through the green state nodes to see how things work visually.<p>You can see some sample state machines in the dropdown in the top left.<p>The power would come from getting folks on the same page of the business process, so engineers can think about how best to automate&#x2F;modernize the system once they get all of the context.<p>Additionally, once you have a single canonical model of the process, you could in theory send into a dark factory to produce the software as quickly as possible, but now we can allocate more time in the entire software lifecycle at the design and alignment before coding now that coding is faster.<p>Additional work could be done using this book for guidance, Workflow Modeling: Tools for Process Improvement and Application Development, <a href="https:&#x2F;&#x2F;www.amazon.com&#x2F;Workflow-Modeling-Improvement-Application-Development&#x2F;dp&#x2F;1596931922" rel="nofollow">https:&#x2F;&#x2F;www.amazon.com&#x2F;Workflow-Modeling-Improvement-Applica...</a><p>MIT licensed repo: <a href="https:&#x2F;&#x2F;github.com&#x2F;RCSnyder&#x2F;tlaplus-process-studio" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;RCSnyder&#x2F;tlaplus-process-studio</a><p>Let me know what you think!<p>Thanks!

Show HN: Pulse – Dashboard for Claude Code, approve tool calls from your phone Hi everyone, I&#x27;m a student from Flanders and I like to use Claude Code for my purposes, ideas and also just for fun and also make solutions for problems in our world!) So that&#x27;s why I built &quot;Pulse&quot;, it&#x27;s an local application that you can easily install to your device and easily follow what your claude agent is doing right now in your terminal session with an ambiance design and easily give permissions for your agent. For those who wants to see directly how much tokens you spent, and how much the session costs, and approve tool calls from everywhere from your phone and everything runs locally without an account can install Pulse from GitHub: <a href="https:&#x2F;&#x2F;github.com&#x2F;nikitadoudikov&#x2F;claude-pulse" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;nikitadoudikov&#x2F;claude-pulse</a>

Show HN: MiniPCs.zip – Charting the Pareto frontier of Mini PCs The overall idea is to chart out the thousands of Mini PCs by benchmark and reveal the Pareto Front so you can get the most Compute per Dollar. Definitely a labor of love as I have a number of Mini PCs for my &quot;homelab&quot; (TrueNAS, piHole, Plex, basic stuff). It uses Gemini to extract specs from listings (since they&#x27;re not often strongly categorized).<p>Quick blog post here: <a href="https:&#x2F;&#x2F;luke.zip&#x2F;posts&#x2F;pareto-pcs&#x2F;" rel="nofollow">https:&#x2F;&#x2F;luke.zip&#x2F;posts&#x2F;pareto-pcs&#x2F;</a>

Show HN: Persona.js – a vanilla-JS agent UI library with native WebMCP (MIT) Hey everyone. My cofounder and I are formally open sourcing (MIT) persona.js. It&#x27;s a VanillaJS library that helps anyone build agentic experiences on the web, without a framework dependency, and full WebMCP support<p>So, why&#x27;d we do this?<p>1) We&#x27;re super fans of the web and the browser can do a ton today<p>2) We&#x27;ve seen AI builds be way overly complex because the FE requires a large project within an existing app OR the site wasn&#x27;t using a framework to begin with<p>If you&#x27;ve been a part of huge apps with multiple frameworks inside them, or work inside CMS &#x2F; website builders &#x2F; ecomm platforms... you know what we&#x27;re talking about. A &quot;simple&quot; AI feature disrupts your life for months<p>If you have a singular React codebase and can&#x27;t possibly imagine building an interface without JSX, nothing to see here! You already have a lot of great options that are really cool too. Check out Assistant UI &#x2F; CopilotKit &#x2F; AI Elements which are all MIT<p>----<p>Some specifics:<p>Persona has a ~15 kB brotli to first paint (the full widget lazy-loads on first click) while being able to render most of the primary agent experiences you see on the web: from &#x27;Fin&#x27; (pill launcher) to &#x27;Claude&#x27; (fullscreen assistant) to &#x27;Shopify Sidekick&#x27; (docked)<p>You can run it in Shadow DOM isolated mode so existing styles play nice<p>Everything has hooks and events, so you can add unique flavor (and easily share back!) in a few lines<p>We have a ton of demos on the library site, along with all the knobs to play with how each aspect renders. Tool and reasoning, custom loading animations, voice, approval UX, etc<p>We&#x27;ve also added a ton of examples across agent and frontend stacks<p>Check out the code @ <a href="https:&#x2F;&#x2F;github.com&#x2F;runtypelabs&#x2F;persona" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;runtypelabs&#x2F;persona</a><p>Feedback and contributions welcome!

Show HN: My Windows XP portfolio with working Game Boy and iPod I posted my portfolio here about a year ago (<a href="https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=45154609">https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=45154609</a>) and while there was a big response, it was very mixed! It&#x27;ll probably be similar this time, but regardless of your thoughts about the concept, I think I&#x27;ve done a pretty good job creating one of the most nostalgic corners of the internet, especially with the latest additions.<p>It&#x27;ll always be up for debate whether this is an effective way to get noticed as opposed to a standard, quick and easy portfolio, but I&#x27;ll die on the hill that this is way more fun for both parties, every day of the week.
