Show HN: I'm writing an MMORPG game for learning programming
Hi, I've been developing an HTML5 MMORPG game where people can submit code to play a game, like collect items, destroy defense towers or kill monsters, etc.. I've been working on this for over 1.5 yrs (all my spare time) and now it's ready for preview, does anyone want to try it out? It's mostly opensource (and the rest will be opensource sooner or later)<p>Please access it with PC, it's an HTML5 game: <a href="https://bytelegend.com/" rel="nofollow">https://bytelegend.com/</a><p>I really want it to expand to more languages, but right now I've only finished Java part. I wonder if anyone can help me with other languages. Besides, I'm not a good game story designer, but I really really want it to be a game with a fantastic story. Any help will be appreciated.

Show HN: PDF API – Generate, convert, and modify PDF documents
Hi HN,<p>Arek here. We’re super excited to officially launch PSPDFKit API [1].<p>PSPDFKit API is a collection of HTTP APIs that enable you to convert, generate, and edit documents without running any service on your infrastructure.<p>What differentiates our API from others is that you can chain together multiple “actions” as part of a single API request. For example, you can convert, OCR, watermark, edit, and flatten a document — all in one call.<p>Available actions [2]:<p>- PDF Generator<p>- PDF Converter<p>- Image Converter<p>- OCR<p>- Watermark<p>- Merge<p>- Split<p>- Duplicate<p>- Delete<p>- Flatten<p>Our documentation includes sample code for JavaScript [3], Python [4], Java [5], C# [6], PHP [7], and the command line. We also have a Postman collection [8].<p>Let us know what you think or if you have any questions.<p>[1] <a href="https://pspdfkit.com/api/" rel="nofollow">https://pspdfkit.com/api/</a><p>[2] <a href="https://pspdfkit.com/api/documentation/tools-and-api/" rel="nofollow">https://pspdfkit.com/api/documentation/tools-and-api/</a><p>[3] <a href="https://pspdfkit.com/api/tools/javascript/" rel="nofollow">https://pspdfkit.com/api/tools/javascript/</a><p>[4] <a href="https://pspdfkit.com/api/tools/python/" rel="nofollow">https://pspdfkit.com/api/tools/python/</a><p>[5] <a href="https://pspdfkit.com/api/tools/java/" rel="nofollow">https://pspdfkit.com/api/tools/java/</a><p>[6] <a href="https://pspdfkit.com/api/tools/csharp/" rel="nofollow">https://pspdfkit.com/api/tools/csharp/</a><p>[7] <a href="https://pspdfkit.com/api/tools/php/" rel="nofollow">https://pspdfkit.com/api/tools/php/</a><p>[8] <a href="https://pspdfkit.com/api/documentation/getting-started/postman-collection/" rel="nofollow">https://pspdfkit.com/api/documentation/getting-started/postm...</a>

Show HN: Civic – Online Hub for Causes
Hi HN! Matias and Jessica here, we're the founders of Civic (https://civicapp.co/), an online platform that connects people to causes in their area. That could mean everything from volunteering opportunities to activism and politics.<p>Every year, over 180M Americans contribute to social causes, yet doing so takes a significant amount of time and energy — information on how to get involved or take action often spreads through disconnected pages, newsletters, and word of mouth. Civic plans to solve this by creating a hub for people to find and organize events, connect, and donate to causes around them.<p>We just launched our MVP in NYC, focusing exclusively on events. I (Matias) started working on Civic while still in college, where I also spent a lot of my time in politics, having worked with ActBlue and a presidential campaign. I also served as a hyper-local elected official in DC, where I represented about 2k constituents to the city. Jessica is a full-stack software engineer and spent 5 years working at Google before joining us. She's fully responsible for our tech and is the reason why we're able to build this at all.<p>During my time in DC, one of the most interesting things I observed was how the causes that were most likely to get people engaged were the local/neighborhood issues that affected them directly. Yet, because of their local nature, those causes were also the ones least likely to get publicity. That plus the general lack of a true online hub for civic engagement led us to start Civic.<p>The MVP is rough around the edges and we're definitely looking for ideas and feedback on how we can improve! Some of the features in our dev pipeline include an onboarding process to customize the content seen by each user (causes are very broad); easy and streamlined, no-fee donations to organizations; social "spaces" based on location and interests where users can meet and discuss issues with others; and much more!<p>For those curious about revenue, we plan to monetize by introducing donations. Right now, over $300B are donated by individuals to non-profits in the United States each year, much of which goes through outdated platforms that charge high fees. We'd target smaller, local organizations that aren't well served by existing platforms, and would follow the same model as GoFundMe and a few other companies, allowing users to add an optional "tip" to Civic after each donation. From our research, this tends to lead to tips of about 6-8% per transaction.<p>You can check out our MVP here: https://civicapp.co/<p>We'd really appreciate any and all feedback (especially related to features, new and existing), please let us know what you think! :)
Show HN: Partially encrypt a file based on its HEREDOCs
Hi HN!<p>I wrote a tool that partially encrypts files based on the presence of a HEREDOC.<p>Check it out:
https://github.com/higgins/privatize<p>When added to a git repo, it will automatically transparently encrypt/decrypt files you want privatized.<p>For example if you configured your repo to privatize the file `example.txt`, you could write:<p><pre><code> ```
Today I a burrito.
<<PRIVATE
I was on the toilet for hours.
PRIVATE
I got a lot of reading done.
```
</code></pre>
but when git-commit'ed would become:<p><pre><code> ```
Today I a burrito.
<<PRIVATE
xuJ0fld2vmNWaVLogTIufmWsiFso
PRIVATE
I got a lot of reading done.
```
</code></pre>
Diffing works as you expect (on the unencrypted source) and only those with the `privatize` symmetric key would be able to unlock and decrypt these files.<p>Why did I do this?<p>I keep a public log of what I plan to accomplish and what I'm working on both personally/professionally.
At the end of the day, I write a summary of everything that happened.
Naturally, there are some details of my life that should be kept private (details of too-be-launched projects, sensitive family events, etc).<p>It's helpful for me to track everything in one file so as to keep the day's context together.<p>Would love to know what you think!
