I've become a bit addicted to online education. I finished my first masters degree in Computer Science in July, and I started a masters in Mathematics from The Open University at the beginning of October. I've wanted to really get into the weeds of obscure and arguably-useless math for about as long as I can remember, and I figure that getting a masters in it is as good a way to get that knowledge as any way else. Ot…

Can you tell me more about your experience doing a maths degree at Open University; what courses have you done or starting? Are there live lectures or is it just self paced? What about tutorials?

I will not. Go away.

Just kidding. I just started last Saturday, so I can’t speak much to it. Thus far it has been primarily assigned reading and practice courses. There is an assignment due in November that I need to start which I haven’t yet.

I am taking analytical number theory and fractal geometry.

It’s not really self paced; you can go a little ahead but you can’t speed through it like WGU.

Currently a one-man side project: https://laboratory.love Last year, PlasticList found plastic chemicals in 86% of tested foods—including 100% of baby foods they tested. Around the same time, the EU lowered its “safe” BPA limit by 20,000×, while the FDA still allows levels roughly 100× higher than Europe’s new standard. That seemed solvable. Laboratory.love lets you crowdfund independent lab testing of the specific p…

Where can I subscribe to pay $20/mo to whatever happens to be the current leader unfunded product?

Update: a donation page with both recurring and one-time donations is now live!

Donated funds are pooled and allocated to the leading unfunded product anytime the pool can get that product to its funding goal.

This is really cool and I was hoping something similar existed earlier this year when looking into protein powders following the Clean Label Transparency Project report [1]. Basically they said about half of protein powders tested showed signs of heavy metals, but did not disclose which brands. I would be interested in funding testing for some specific brands as I am sure others would as well. I did a bit of digging…

Awesome, thanks for the feedback. I will look into Labdoor and their funding models. I'm definitely open to expanding to other types of testing if/when this project grows. I'm actually already able to test for nearly everything you'd want to check for in a consumable, I'm just keeping the focus of the public website on plastic chemicals for now to avoid feature creep and scope management issues.

I have considered creating specific ad-hoc campaign pages for folks with special interests and let them drive people to the page (like a more focused Kickstarter or GoFundMe with a lab on the back end).

If anyone has a special interest I'm happy to mock up what funding targets would be.

A couple of months ago, I saw a tweet from @awilkinson: “I just found out how much we pay for DocuSign and my jaw dropped. What's the best alternative?” Me being naive, I thought “how hard could would it actually be to build a free e-sign tool?” Turns out not that hard. In about a weekend, I built a UETA and ESIGN compliant tool. And it was free. And it cost me less than $50. Unlimited free e-sign. https://useinkless…

Didn't someone else do this recently and then DocuSign sued them?

I've been suffering from migraines for the last month, so have channeled my (non-migraine) time into a migraine tracker to try and find the root causes. All the tracking apps I tried all have nice complex forms, which is all well and good, unless...you are having a migraine. Rough idea is easy to use voice mode to record data, then analyze unstructured data with AI later on. I want to track all relevant life informat…

Hey, I found that daily dose of vitamin B almost completely stopped mine. There is evidence to back this up (though I don't have the reference on me), but also be careful as excessive amounts of VB can cause nerve issues.

Training ML models for PDF forms. You can try out what I’ve got so far with this service that automatically detects where fields should go and makes PDFs fillable: https://detect.semanticdocs.org/ Code and models are at: https://github.com/jbarrow/commonforms That’s built on a dataset and paper I wrote called CommonForms, where I scraped CommonCrawl for hundreds of thousands of fillable form pages and used that as a…

Congratulations on being featured in the Superhuman newsletter. Trying it out.

Woah, did not realize that, haha. Let me know if it works well!

Building https://typequicker.com

Hoping to make the best typing application.

Key features:

- absolutely no ads; this an education tool

- SmartPractice: we use a time series db to track weakpoints (bigrams, individual characters, etc. their time to type and errors) and then select the most relevant ones to generate typing practice text

- advanced stats; after each session we provide the most detailed stats than any typing platform

This a passion project that turned to a business.

Hope you try it :)

As an author, I'm working on different stories and projects all the time. Main thing is to keep thinking of new things to do, I've already written and self-published 20+ short stories, and I've written two middle-grade scifi novels.

One thing I've come to understand about the process is that becoming a self-sufficient author is very similar to being a startup - only you're a startup of yourself. Building the product, building your market, building the infrastructure, watching what your other 'startups' are doing - it's all part of the process.

In the past days, I've released one of my stories as a 'Make Your Own Adventure' - https://inkican.com/make-your-own-scifi-adventure-now/

I've also integrated Bluesky into my blog comments: https://inkican.com/test-driving-a-new-comment-platform-blue...

And I've created some free STEM content for K-6 teachers on the future of space elevators: https://inkican.com/space-elevators-getting-to-the-next-leve...

Going to continue with my ideas and I appreciate the chance to tell you about them. Thank you. :)
