Currently working on an advanced analytics tool for 0DTE trade data, which allows to scan through massive amounts of data in the least amount of time, find seasonal patterns created by institutional investors, blast credit chains for profitable trades and simulate / backtest arbitrary trades in conjunction to create portfolios. So far the software yielded several successful trading strategies, which outperform standard approaches ever since the new administration in the US came to power. Currently in closed beta but planning to release around Xmas eventually.

Working on a advanced analytics application for 0DTE trades, that allows to analyse thousands of possible trade curves in the least amount of time.

The process itself is extremely time consuming, when done manually. My application speeds up the process by a factor of 50 up to 150, depending on how you measure it.

Finally it allows "everybody", to find the 0DTE trades, that are really profitable - something, that currently only the "Pros" can do.

As always put together perfectly. Not only fun to read, but also a new item on my todo list.

How do you define market leader? In 2021 they had 14 million paying customers and a market share of 72 percent. If that’s not a market leading position, I don’t know what is. I don’t favor them, it’s a real pain sometimes, but they operate a tanker, not a speed boat.

At https://metrik.one/ we developed an advanced analytics app for Mailchimp customers and we currently experiment with a LLM powered natural language interface, which allows to define queries w/o having to understand SQL or to rely on predefined charts. LLM integration into analytics will IMO be the norm quite soon, since it can be a massive timesaver and makes otherwise static analytics applications really versatile from the users point of view. We're still in a POC phase but hope to beta-test the feature soon.

Advanced analytics for Mailchimp. It provides deep insights into subscriptions, opens, clicks and campaigns. In addition it comes with advanced segmentation based on subscriber behaviour instead demographic data. And it includes a cohort analysis, that helps to reduce inbound ad cost dramatically by not just focusing on CAC but prospect groups that actually open and click.

We built it out of our own need (running https://8bitnews.io/) and target newsletter senders, who prefer data driven decision making.

Instead of building the next SaaS we decided to build a desktop app. Privacy and data protection were the main drivers behind that decision.

Currently in beta, but close to a release and seeking market validation.

I can imagine there’s a direct connection to Apples announcement on Sep 7th. I don’t recall all the details, but read a report, that Apple bought a partially defunct satellite network, that has only very few, but therefore geostationary satellites which come with bandwidth licenses that exceed Starlink’s by a lot. Might be totally wrong, but did anybody else hear that rumor?

We built https://metrik.one

It’s an advanced analytics tool for Mailchimp. It’s mostly targeting regular newsletter senders, but gives detailed insights into an audience w/o violating user privacy. We like to think about it as the Plausible for Email Marketing. Unfortunately the development took too long, my business partner and friend ran out of runway and my kid was born. Still planning to market it, but so far under the radar.

There are plenty of resources for the Curta just a Google search away. Especially scans of the original manuals can be found. Try this one here: http://www.curta.de/kr34/

Does anyone also feel reminded of the TCAP or Transcapacitor or Transfer Capacitor story / hoax from 1998?

Don’t know how it was done back in the days. But dumping a ROM should be straight forward. The resulting machine code can be massaged into assembly using a disassembler. 6502 assembly is kind of easy to read, since the instruction set is small compared to modern day CPUs. Once you identified a routine you want to change, you look up the instructions address in ROM, and hijack the corresponding addresses at runtime to put your own instructions and data on the bus. For sure everything but easy, but totally doable.

Great work! You might like https://github.com/janroesner/sixty5o2 as a lightweight OS for the BE6502, which makes program changes way easier.

8bitnews here: RSS is coming ...

I just finished with our own micro publishing platform, currently building a tool to solve a huge problem that publishers have, and work on a hardware whose build process will be documented in an educational video series. Burning through saving with a maximum of fun.

What complexity? Just sign up at Mailchimp, write your email and done! So we thought ... then we realized, there is more. Plenty.

We recently discovered two projects that fit into the modern-retro approach and published short articles here:

The CERBURUS is a mix between an C64 and a ZX80/81 and the MiniPET is a pure re-creation of the original PET.

A spam free newsletter from geeks for geeks. From Commodore to Atari, from C64 to NES, from breadboard machines to emulators, assemblers and compilers. 8bitnews delivers the latest content, filtered, curated and spamfree.

The 65C02 does (as well as AFAIK the 6510) if one compiles VASM with the according flags. Ben decided not to do so, neither did I for the feeling of good old times. Why make it easy ;)

I found “Digital Computer Electronics” by Malvino and Brown really helpful. It starts from scratch. Was also a recommendation from Ben Eater, but you will only find used copies, since the book is not in print no more.

You are more than right. This is just my first assembly project in 20 years, put together from scratch in a couple of days. Therefor I am more than greatful for every constructive hint, that helps me improve. Thanks!

Valuable collection Dave! Brilliant as always. Thx for putting this together.

In 2013 I built an app essentially for myself to solve the recurring problem of sales tax declaration in Germany. I have to do this quarterly or monthly and filling out all the official forms was painful and time consuming. So I came up with

http://kassomat.net

An SPA with a simple yet accurate approach where you just enter 4 key numbers and are done in under a minute.

Due to my recent lack of time I was not able so far to adjust the App to the latest official API's, but that's doable. Open to offers.

I made http://kassomat.net - a tool for desktop and mobile which let's you declare sales tax in under a minute. Current scope is Germany only.
