Show HN: Val Town – A Cloud Scripting Site
Hey HN! We're so excited to show you Val Town (<a href="https://val.town" rel="nofollow">https://val.town</a>)! A "val" is a JavaScript/TypeScript function or value that runs on our servers. We aim to get you from idea to running code in seconds: type code, run it, get its API endpoint, schedule it - all from the browser, in a couple keystrokes.<p>We're a startup of 4 people, mostly in NYC. We've been working on this for 6 months and are eager for feedback from the HN community.<p>Why do we need yet another online coding IDE? While researching devtools[1], I found myself wanting something halfway between Replit and Zapier: a tool that makes hosting, deploying, scheduling, and authenticating easy, but is first-and-foremost a programming tool.<p>We added `console.email` to the runtime to make it incredibly easy to email yourself. We don't have npm imports yet, but we do have a low-friction system that treats every user as a namespace, so you can refer to `@me.foo + 1` or `@yourFriend.bar()` right in your code. There are a lot of thorny implications this newfangled import scheme creates, but also many joyous and carefree coding experiences! One of my favorite features is that we store every evaluation, up and down the callstack, including inputs, outputs, logs, etc, which has been an amazing aid to debugging.<p>So far, Val Town is mostly used for what we're calling "programmatic notifications": query a data source for new items on an interval and email them to yourself.<p>Get notified when users you "follow" post on Hacker News: <a href="https://www.val.town/stevekrouse.hnFollowPollJob" rel="nofollow">https://www.val.town/stevekrouse.hnFollowPollJob</a><p>Get notified when to close your window during fire season in SF: <a href="https://www.val.town/stevekrouse.aqi" rel="nofollow">https://www.val.town/stevekrouse.aqi</a><p>Get notified when there are new citations on a paper: <a href="https://www.val.town/ernest.newCitationNotification" rel="nofollow">https://www.val.town/ernest.newCitationNotification</a><p>Subscribe to RSS feeds: <a href="https://www.val.town/stevekrouse.pollRSSFeeds" rel="nofollow">https://www.val.town/stevekrouse.pollRSSFeeds</a><p>A good place to get started would be forking one of those vals and modifying it to suit your needs. Some folks are using the tool in other ways, such as in webhook contexts, and we encourage those uses as well. We'd LOVE to pair-program with anyone looking to try out the tool and give feedback.

Show HN: Ecode – A minimalist and fast open-source code editor
Hi HN! I've been working on a code editor and I think that it's mature enough to catch some interest. It's using a custom GPU accelerated GUI written in C++. Currently implements some interesting features: LSP, terminal, auto-completion, linters, formatters, custom keybindings, plugins and more. It's a hobby project but still intends to be an alternative to other popular code editors like Sublime, Kate, Lapce, Lite XL (and takes inspiration from them).<p>The project was born as a playground for the GUI I'm developing (eepp GUI) and is advanced enough to currently be my main code editor, but it's a work in progress, and many features are still pending. Some minor hints on how to use it:<p>Folders are used as project (and .gitignore is used to ignore files)<p>The wheel icon on the top-right has all the options you need (Ctrl/Cmd + M to show).<p>Some keybidings to navigate any project (navigation is keyboard driven):<p>Ctrl/Cmd + K = Locate Files<p>Ctrl/Cmd + Shift + F = Global Search<p>Ctrl/Cmd + Number (Go to tab #)

Show HN: Futurecoder – A free interactive Python course for coding beginners
Some highlights:<p>- 100% free and open source (<a href="https://github.com/alexmojaki/futurecoder">https://github.com/alexmojaki/futurecoder</a>), no ads or paid content.<p>- No account required at any point. You can start instantly. (You can create an account if you want to save your progress online and across devices. Your email is only used for password resets)<p>- 3 integrated debuggers can be started with one click to show what your code is doing in different ways.<p>- Enhanced tracebacks make errors easy to understand.<p>- Useful for anyone: You can have the above without having to look at the course. IDE mode (<a href="https://futurecoder.io/course/#ide" rel="nofollow">https://futurecoder.io/course/#ide</a>) gives you an instant scratchpad to write and debug code similar to repl.it.<p>- Completely interactive course: run code at every step which is checked automatically, keeping you engaged and learning by doing.<p>- Every exercise has many small optional hints to give you just the information you need to figure it out and no more.<p>- When the hints run out and you're still stuck, there are 2 ways to gradually reveal a solution so you can still apply your mind and make progress.<p>- Advice for common mistakes: customised linting for beginners and exercise-specific checks to keep you on track.<p>- Construct a question that will be well-received on sites like StackOverflow: <a href="https://futurecoder.io/course/#question" rel="nofollow">https://futurecoder.io/course/#question</a><p>- Also available in French (<a href="https://fr.futurecoder.io/" rel="nofollow">https://fr.futurecoder.io/</a>), Tamil (<a href="https://ta.futurecoder.io/" rel="nofollow">https://ta.futurecoder.io/</a>), and Spanish (<a href="https://es-latam.futurecoder.io/" rel="nofollow">https://es-latam.futurecoder.io/</a>). Note that these translations are slightly behind the English version, so the sites themselves are too as a result. If you're interested, help with translation would be greatly appreciated! Translation to Chinese and Portuguese is also half complete, and any other languages are welcome.<p>- Runs in the browser using Pyodide (<a href="https://pyodide.org/" rel="nofollow">https://pyodide.org/</a>). No servers. Stores user data in firebase.<p>- Progressive Web App (PWA) that can be installed from the browser and used offline.<p>-----------<p>A frequent question is how does futurecoder compare to Codecademy? Codeacademy has some drawbacks:<p>- No interactive shell/REPL/console<p>- No debuggers<p>- Basic error tracebacks not suitable for beginners<p>- No stdin, i.e. no input() so you can't write interactive programs, and no pdb.<p>- No gradual guidance when you're stuck. You can get one big hint, then the full solution in one go. This is not effective for learners having difficulty.<p>- Still on Python 3.6 (futurecoder is on 3.10)<p>I am obviously biased, but I truly believe futurecoder is the best resource for adult beginners. The focus on debugging tools, improved error messages, and hints empowers learners to tackle carefully balanced challenges. The experience of learning feels totally different from other courses, which is why I claim that if someone wants to start learning how to code, futurecoder is the best recommendation you can make.

Show HN: I spent 2 years building Tablane as a 17-year-old
Hi HN community,<p>I'm Marcus, a 17-year-old Software Engineer from Germany.<p>For the past two years I've been working on Tablane [0](<a href="https://github.com/Tablane/tablane">https://github.com/Tablane/tablane</a>) a task/project management tool, with features like:<p>- Collaborative Editing (google docs)<p>- Optimistic updates with RTK Query<p>- Realtime sync with Socket.io<p>- An awesome design<p>Let me know what you think! Ask me anything!<p>How I got here:
2020: I was developing a TTT [1] (Trouble in Terrorist Town) plugin for my minecraft server, when I started to require a project management tool to keep track of the features I wanted to implement, originally I used a text file, but after some time I started using products like ClickUp and Monday.<p>But not long after I hit several paywalls for features that I wanted to use (Custom Status, Limited Number of Boards, ...)
Soon after Tablane (originally task-board) was born. I started building the website using plain HTML, then found out about React and completed Colt Steele's "Web Developer Bootcamp" [2] and "The Modern React Bootcamp" [3] and started re-writing Tablane in React, and started adding feature after feature.<p>Now I am about to finish Highschool and originally I thought about applying to college and spending another 3-5 years there, but after the positive feedback I got on a three month internship I did at ContentPepper, and seeing how my own projects developed, I decided to look for open Developer positions, to work with a team of experienced developers so I can learn even faster.<p>Links:<p>[0] <a href="https://tablane.net" rel="nofollow">https://tablane.net</a><p>[1] <a href="https://github.com/MarconLP/TTT">https://github.com/MarconLP/TTT</a><p>[2] <a href="https://www.udemy.com/course/modern-react-bootcamp/" rel="nofollow">https://www.udemy.com/course/modern-react-bootcamp/</a><p>[3] <a href="https://www.udemy.com/course/the-web-developer-bootcamp/" rel="nofollow">https://www.udemy.com/course/the-web-developer-bootcamp/</a><p>Socials:<p>Résumé/CV: <a href="https://drive.google.com/file/d/1CbZi1Bm-MlDHEb4WjsFBzIBSomJa1M7T/view?usp=share_link" rel="nofollow">https://drive.google.com/file/d/1CbZi1Bm-MlDHEb4WjsFBzIBSomJ...</a><p>LinkedIn: <a href="https://www.linkedin.com/in/marcus-hof/" rel="nofollow">https://www.linkedin.com/in/marcus-hof/</a><p>Email: marcus (dot) hof (at) protonmail (dot)com<p>GitHub: <a href="https://github.com/MarconLP">https://github.com/MarconLP</a><p>Twitter: <a href="https://twitter.com/Marcon565" rel="nofollow">https://twitter.com/Marcon565</a>

Show HN: ClickHouse-local – a small tool for serverless data analytics
Me with my friend Vitaly Ludvichenko made an experiment to combine ClickHouse server and client to make a self-contained program running a database engine and processing data without a server: <a href="https://github.com/ClickHouse/ClickHouse/pull/150">https://github.com/ClickHouse/ClickHouse/pull/150</a><p>Development continued in the past 6 years, and now clickhouse-local becomes a swiss-army knife for data processing. Say "ffmpeg" for datasets and more.<p>It can resemble textql, octosql, dsq, duckdb, trdsql, q, datafusion-cli, spyql, but has better capabilities and performance.<p>Here is a tutorial: <a href="https://clickhouse.com/blog/extracting-converting-querying-local-files-with-sql-clickhouse-local" rel="nofollow">https://clickhouse.com/blog/extracting-converting-querying-l...</a><p>"serverless" in the same sense as here: <a href="https://www.sqlite.org/serverless.html" rel="nofollow">https://www.sqlite.org/serverless.html</a>
and also in the more common sense - clickhouse-local can be packaged into AWS Lambda and serve queries on a per-request basis, as here: <a href="https://github.com/ClickHouse/ClickHouse/issues/43589">https://github.com/ClickHouse/ClickHouse/issues/43589</a>

Show HN: Pole Clock, a single 24h clock with multiple timezones
Hi HN! I designed this Pole Clock to be a helpful tool for people like myself who often struggle with managing their sense of time.<p>I found that analog clocks are generally easier to read and understand than digital ones, however I find the fact that every day is broken into two 12-hour rotations unintuitive. A single 24-hour rotation makes it easier to grasp where in the day you are, the bottom half representing night and the top half representing day.<p>Additionally, because the clock displays 24 hours, you can add extra hour hands on the clock for other time zones. This is especially useful if you work remotely or have friends and colleagues in different time zones. At a single glance, see where they are in their days and energy levels!<p>I hope you'll give the Pole Clock a try and find that it helps you better understand and manage your sense of time.
