Show HN: Jendeley – JSON-based document organizing software
I created jendeley to help organize documents for programmers.<p>- jendeley is JSON-based. You can see and edit your database quickly.<p>- jendeley works locally. Your important database is owned only by you. No cloud.<p>- jendeley is browser-based. You can run it anywhere node.js runs.<p>Repository: <a href="https://github.com/akawashiro/jendeley">https://github.com/akawashiro/jendeley</a>

Show HN: G-Script – Visual Scripting for the Web
Hi all,
I'm a PM by day who taught themselves to code over COVID. One of the things I enjoyed during that process was learning how to make basic games in Unreal Engine using Blueprints. I found visual scripting was such an intuitive way to express what I call "mid-tier complexity" logic and I felt there really wasn't a great equivalent for the web - so I built one over the last few months and this is my MVP.<p>Tools like Zapier etc are great and easy to use, but they're heavily limited when it comes to expressing any kind of complex logic or trying to follow coding principles like DRY.<p>On the other end of the spectrum, serverless setups like Cloudflare workers or Firebase functions give you all the power of code, but there's atleast 20-30 minutes of additional overhead involved in just getting the things live.<p>G-Script is designed to land exactly in the middle of these two options. It's "Lower level" than tools like Zapier and supports most of the code-level primitives you NEED in order to express logic.<p>Examples being:
- Conditional Logic
- Loops
- Static Typing
- Objects & Arrays
- Version Control
- Reusable logic/functions<p>On the flip side, it's much less friction that writing an actual serverless function, both up-front and ongoing.<p>Examples:
- You don't need to know "Code", just how to express your logic visually.
- No need to manage even basic deployments or use a CLI, it's all done via a UI.
- Every Workflow is a seperate little microservice with it's own URL that you can call via HTTP.
- The super simple version control system makes it easy to role back to earlier versions of a workflow if you break something, or make changes to your logic without impacting what executes and the Workflow URL until you're ready to deploy your final iteration.

Show HN: Experimenting with GPT-3: Building an Investment Analyst
We have been experimenting with using GPT3's reasoning capabilities to build an investment analyst that does this :<p>(1) Summarize relevant news of the last 30 days,<p>(2) Write a SWOT analysis,<p>(3) Identify competitors,<p>(4) Identify Key Risks, and<p>(5) Write three investment theses (bull, neutral, bear)<p>Here is an example how this can look like:<p>https://app.finclout.io/tp/MSFT
https://app.finclout.io/tp/LYFT
https://app.finclout.io/tp/AAPL
https://app.finclout.io/tp/UBER<p>So far, the results of getting reliable data back through well-engineered prompts through the API is quite promising. Yet, from an operational perspective, the biggest problem is that even though we are not using the free service but pay for it frequently run into rate limits.<p>Positives:
For Apple, the News Summary provided a useful result.<p>"Apple Inc. is launching Apple Pay Later soon to revolutionize the buy now, pay later (BNPL) industry. Its stock is currently indicating a potential move to $167. The company is also facing an investigation by the Pomerantz Law Firm on behalf of iPhone 7 owners who experienced performance degradation following a device update. Apple's latest iPhones are being sold at discounts in China and the company is expected to rollout a high-end iPhone 'Ultra' in 2024. Additionally, two top market watchers discussed tech's wild run this year."<p>For Microsoft, the Bull-case made more sense than the Bear-case
Bull-case<p>"Microsoft Corporation is a technology leader in the industry and is well-positioned to benefit from the increasing demand for cloud computing and artificial intelligence. The company's strong balance sheet, competitive advantages, and focus on innovation make it an attractive long-term investment<p>Bear-case
"Microsoft Corporation is a large, mature company with limited growth potential. The company is facing increasing competition from smaller, more nimble competitors and is struggling to keep up with the rapid pace of technological change. Investors should b e wary of investing in Microsoft due to its lack of innovation and potential for declining market share."<p>Negatives:
GPT3 is only guessing the next best word. Which might sometimes provide strange results. For example, considering the News Summary for Uber<p>"Uber Technologies, Inc. reported a surge in fourth-quarter revenues and a strong outlook for 2021."
We are not in 2021 anymore for a long while.<p>Clearly, GPT3's knowledge of the Yahoo finance dataset has been cut off in 2021 and applied the provided news effectively.
For AAPL, GPT3 did not identify any competitors.<p>While we could argue that HP, MSFT, or similar hardware+software companies are in fact, competitors.<p>In conclusion, we need to further investigate if the actual reasoning of GPT3 is mature enough to provide a useful analysis of the stock. Especially under liability considerations.<p>Yet, if it works it could be a really powerful game-changer.<p>Clearly, that is only an experiment and shouldn't be used as an investment recommendation nor seen as investment advice in any way.
Show HN: Enc – A modern and friendly CLI alternative to GnuPG
Enc is a CLI tool for encryption, a modern and friendly alternative to GnuPG. It is easy to use, secure by default and can encrypt and decrypt files using password or encryption keys, manage and download keys, and sign data. Our goal was to make encryption available to all engineers without the need to learn a lot of new words, concepts, and commands. It is the most beginner-friendly CLI tool for encryption, and keeping it that way is our top priority.
Show HN: Log collector that runs on a $4 VPS
Hey guys, I'm building erlog to try and solve problems with logging. While trying to add logs to my application, I couldn't find any lightweight log platform which was easy to set up without adding tons of dependencies to my code, or configuring 10,000 files.<p>ErLog is just a simple go web server which batch inserts json logs into an sqlite3 server. Through tuning sqlite3 and batching inserts, I find I can get around 8k log insertions/sec which is fast enough for small projects.<p>This is just an MVP, and I plan to add more features once I talk to users. If anyone has any problems with logging, feel free to leave a comment and I'd love to help you out.

Show HN: DSLCad – a programming language and interpreter for building 3D models
Hey HN.
Over the last half a year I have been working on a 3D CAD programming language called DSLCAD. Today I am here to show my first release!<p>It is heavily inspired by OpenSCAD which got me hooked on the idea of a CAD programming language and what it can do.<p>Please let me know what you think. Ill be in the thread to answer any questions you may have.
