Show HN: Linux and iPhone Continuity (iMessage / SMS) After switching to 100% Linux a couple of years ago there was basically only one thing I missed about macOS and that was what Apple calls &quot;Continuity&quot;. It&#x27;s where you get texts, notifications, clipboard sync, file transfer (to&#x2F;from) the iPhone from the Mac desktop. Especially that thing where OTP codes via text autofilled into the browser form I was waiting on.<p>It took about 4 months of work:<p>- reverse-engineering Apple&#x2F;iOS Bluetooth behavior<p>- MAP &#x2F; OBEX<p>- Bluetooth LE + Wi-Fi working together<p>- iMessage through the iPhone&#x27;s own cellular&#x2F;iMessage stack<p>- iOS app, Linux daemon, GTK app, Thunderbird&#x2F;Firefox extension<p>- no Mac involved<p>But it is now something I&#x27;d love to show people. Contributions&#x2F;bugs&#x2F;feedback welcome!

Show HN: A new way to read books, magnifying in and out After watching The Odyssey, I thought it would be cool to check out some scenes from the source in detail, but I don&#x27;t have time to read the whole book. So I came up with a sort of zoom&#x2F;microscope, that allows to see the whole book at a glance and then zoom in (by pinching) on the part I&#x27;m interested in. I can do so down to the actual source text and get the authentic feel the author intended, at the same time I better understand where am I in the text and also the character and places are clickable so I can quickly orient myself on the context. Moreover each character has relationships listed and a map of relationships can be opened from there <a href="https:&#x2F;&#x2F;book.curiora.space&#x2F;relations&#x2F;" rel="nofollow">https:&#x2F;&#x2F;book.curiora.space&#x2F;relations&#x2F;</a>

Show HN: CopyLasso, a free local screen OCR app for macOS Hi HN, I made CopyLasso for text you can see but can&#x27;t select: things like scanned PDFs, text in videos, and text in screenshots.<p>I was surprised to find only a few solutions for this that were all paid, so I made a free and open source version.<p>CopyLasso is a native Swift app built with ScreenCaptureKit and Apple Vision. It&#x27;s MIT-licensed, signed, and notarized.<p>To use it, just press your keybind and draw a bounding box around the text you want to copy. The text is recognized locally and copied to your clipboard.<p>Other features include copying QR codes and barcodes, multi-language recognition, and (if you opt-in) encrypted capture history.<p>Source: <a href="https:&#x2F;&#x2F;github.com&#x2F;bennetthilberg&#x2F;copylasso" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;bennetthilberg&#x2F;copylasso</a><p>Feedback and ideas for features to add appreciated!

Show HN: Frugal Tokens – explore costs and usage across coding agents I wanted to share a project I’ve been working on called Frugal Tokens. I originally built it because I was curious to see how much all of my sessions cost and how much cache misses affected that spend. I’d noticed people had widely different spend profiles and wanted to better understand what might contribute to that.<p>As I’ve worked on this, the tool has grown to show more usage patterns across all of your sessions. It shows overall usage, estimated working time and overlapping sessions, and where your spend is coming from across models and cache misses. I also have a few session level metrics with percentile breakdowns, along with a list of your sessions and high level info.<p>Clicking into a session opens an explorer where you can see individual model calls and tool inputs and outputs. You can also jump directly to where a cache miss happened. There’s also a rough cost comparison that shows what the recorded session would have cost with another model’s pricing, or for Anthropic, with 5m vs 1h caching.<p>In the future, I’d love to collect more information to see which patterns might make people’s workflows more expensive, e.g. long sessions, high context usage, many turns, etc.<p>The tool requires deno, but is just one command to run once that is installed. The demo provided has some of the data scrubbed, but helps to show what it looks like before running it.<p>Would appreciate any thoughts or ideas<p><a href="https:&#x2F;&#x2F;github.com&#x2F;dpclark4&#x2F;frugal-tokens" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;dpclark4&#x2F;frugal-tokens</a>

Show HN: My Mac slept through its cron jobs, so I made goguma, a menu bar app Hi HN, like many of you likely do, I run cron jobs throughout the day&#x2F;night, but can&#x27;t afford to have my laptop open all day.<p>So, I decided to build goguma, a free, open-source Mac menu bar app that wakes your Mac only when a cron job&#x2F;automation is scheduled to run. Unlike caffeinate, Amphetamine, or Adrafinil, which can only keep an awake machine awake, goguma can wake a sleeping machine.<p>It automatically imports all your jobs across launchd, crontab, Hermes, etc, alongside detecting agent activity through hooks. The Mac menu bar app will also show you which job it&#x27;ll next wake for.<p>It remains safe by skipping wake-ups if it&#x27;s lower than a battery threshold, and lets the mac sleep if it starts overheating.<p>Happy to hear any feedback and suggestions!

Show HN: Automatically detect and patch walking-dead states in Sierra games Hi HN, I&#x27;ve become lazier in my old age and struggle to replay my favorite Sierra games from the 80s and 90s because I keep getting into those situations where I need an item from 3 acts ago, I have no save game handy, and now I gotta make dinner.<p>So I&#x27;m building the Lucasartsifier: a static analysis tool that decompiles Sierra resource files, automatically finds those states, automatically generates code to prevent the player from getting into those states, then emits loose patch files that can be placed alongside the original game resources. There&#x27;s no game-specific code involved; all the logic is generic, though of course Sierra introduces new idioms and mechanics in every game so every new supported game needs a bunch of engine work.<p>So for example in Leisure Suit Larry 2, the patched game prevents you from boarding the cruise ship until you have both the sunscreen and the Grotesque Gulp. Without them you die on the raft 3 play-hours later.<p>So far this works on Leisure Suit Larry 2 (SCI0), King&#x27;s Quest 4 (SCI0), King&#x27;s Quest 6 (SCI1.1), and Laura Bow 2 (SCI1.1). I&#x27;m currently working on King&#x27;s Quest 5 (SCI1.0).<p>This is work done with Claude -- I do the design and playtesting and it does the rest :D<p>Any feedback, play testing, and suggestions would be great!
