Carpet based localisation! I need a location tracking system for my office robot. Our carpet happens to have a pseudo random grid pattern of four colors. I'm creating a map of this pattern, then at runtime I fuse odometry with carpet colour (detected via camera) in a particle filter to determine and track robot location. Initial results are looking good :) Some links : How I detect carpet colour: https://nbviewer.jup…

Is the gaussian mixture model required for this? Can't you just use the nearest neighbor?

Paced Email – https://www.paced.email

My email side project is a year old and is starting to really come into it's own now.

It allow you to silence emails by bulking them into a single daily, weekly, or monthly digest. The email aliases are "programmable" on the fly or can be created with a Chrome/Firefox/Safari browser extension.

An analytics platform for active retail traders.

A lot of folks have several trading accounts which provide varying degrees of analytics. I’ve found that consolidating the transaction history across these accounts to build a deep level of analytics manually is time consuming.

I’m leveraging the incredible open source Zipline library for the analytics. It’s like backtesting your actual trading activity.

I’ve been working on this on and off for almost three years and am just about to launch.

1. The documentation toolchain, process, and content for a Silicon Valley startup. 2. A neurosymbolic-processing system (in other words, a symbolic knowledge-based AI system that coordinates a raft of neural-network and machine-learning systems) for machine control for several U.S. federally-funded projects. 3.

An app to help couples learn each other's languages ( https://learncoupling.com ) My wife is Chinese, and I've been learning Cantonese and Mandarin off-and-on on my own for years. For many reasons, I recognize it's extremely difficult to make it work to acquire a language with the help of a romantic partner. I even had a friend who's wife was a doctorate in French language education but completely failed to use her a…

Hey, looks really cool. I subscribed. Seems that its only made to learn one language, right? I for example have the situation that I need to learn my wifes mother tongue and she needs to learn mine, will that be possible?

An easy to use decentralised data storage platform

Since Google started charging for storing photos, I decided to store my data myself.

I have a raspi with an external hard disk with a custom made server, thinking of ways to make it easier to set up so that non tech savvy people can use it too. I don't like big corps holding my data and then charging for it, I'd rather store it myself and pay for it.

Yes I know it's relatively volatile and can go down when my WiFi is down but then I won't really be using the cloud anyways.

A browser extension called Curb Your Consumerism that detects when you are on a checkout page and shows you how long it took you to earn enough money to complete that purchase. The idea is about increasing the mindfulness of your purchases and reducing unnecessary environmental waste driven by impulse buying. Here's what I'm planning next: - Detecting the checkouts and extracting the checkout total generally across w…

I think a great opportunity could be the FIRE community. I think a lot of them think in terms of "if spend X amount I have to work Y more days before retirement". At least I try to do that. The problem is I don't really know how to calculate Y, if your plugin could translate the dollar amount on the checkout page to the number of days I have to work extra that would be really cool.

This of course depends on my savings rate, current assets and expected return on investments.

Either way, cool stuff!

I have developed a blog about ALS disease (Lou Gehrig disease). [0]

I wrote also a book about the state of ALS research (updated on February 1) [1]

I would be interested in exploring the idea of using Cell Penetrating Peptides (or PROTAC) to either relocate or remove entirely TDP-43 aggregates. It could be studied at low cost on Ciona (an aquarium animal that looks like a plant). If someone is interested my email address is in my profile. Ciona intestinalis has motor neurons and can even regenerate its entire nervous system in only one month!
