I started working on getting my private Wordpress plugin and theme update service out of beta. It's getting closer! Maybe by the end of the month. https://kernl.us - Come check us out!

Dealing with private, or non-repo updates myself recently, I've been exploring what it takes to do these. Currently I'm using Freemius, but I'm sure at some point I'll have to make this work. I'm excited to see another option out there!

An implementation of hyperorthogonal (aka ZigZag) data structures in Scheme [0], that respects the bottom-up, dynamic extensibility envisioned by T. Nelson. [0] https://www.github.com/jpt4/chanadu

I'm working on a related project that uses hyperorthogonal data structures to create better bookmarks:

I've been having fun the last few months by creating and launching! The latest of which seems to have struck a chord: MailScope http://www.mailscope.io adds profile data to your existing mailing list. Why? Well, if you don't ask for firstname and lastname on signup, you'll get increased conversion. But if you then want to get increased open and click rates when you actually send email, you should start personalizing…

Interesting idea how do you get the names? My initial idea would be to crawl some social networks for the name.

It's been a really fun break! I'm getting interested in super low frequency signals so I looked up the E202 Very Low Frequency ( I think it would be awesome to go find a pipeline to use as an antenna... Next project is to take my BlueROV[3] and build a hydrophone array[4] for it so a friend and I can see if a underwater acoustics engineer friend and I can use it to track other objects (like a remote-controlled toy bo…

FWIW, you may wish to add a 50Hz notch filter as well. If you're in North America 50Hz noise won't be as much of an issue, but if your receiver is sensitive enough there's likely still enough of it floating around from various DC-AC inverters and the like. Of course, if you've got a good enough tuner you can likely just measure the noise in that "band" yourself. Re: using a pipeline as an antenna - I wonder how diffi…

Thanks for the suggestion, I'll do that! I posted partly in hopes that somebody would reply and solve problems I didn't know I had. That's the joy of being totally new to this stuff. I don't know what I don't know. :D

Re: using mains power lines... I actually have a friend who might be able to answer that, so I'll ask him. We were also considering transmission towers, since plenty of the hikes I know will take me across a clearcut for the transmission lines, and I can get some altitude with good, unobstructed views.

I'm also building a data driven (mostly NLP) portfolio optimizer, based on expected utility theory! It's a naive model, but it also has statistical bounds on its efficiency relative to the regret, which is an interesting bonus. Out of curiosity, what kind of model (loss function) are you using?

Still very early.

Currently I am planning combining quantitative and qualitative data (mainly NLP and sentiment analysis). The main goal is to build a robust system.

Therefor I am working on implementing Minimax and Tail-Risk-Hedging as a Spiking Neural Network.

I'm rethinking the computer. The hardware, the software, the UI paradigms, everything. Xerox PARC 2.0. - We must stop writing UI by hand - We must adopt a new language that's less ambiguous - We must prefer graphs to trees - We must not build service-specific apps and websites - We must stop thinking of computer hardware as a personal device, and make switching from a device to another completely seamless - Local sto…

Earlier quoted context omitted.

What exactly are you doing? I've been gathering data for few seasons in my league, going to use it to help me draft next year.

My first pass is actually attacking daily fantasy (i.e. given data about past NHL games, predict a player's performance in an upcoming game). I'm scraping some NHL stats sites to build input vectors based on a couple dozen manually-chosen features (e.g. "number of goals scored last game", "opposition goalie's save percentage in his last 5 games") and passing them through a neural network to see if there's any usable…

Very cool. I'd check the fantasyhockey subreddit, I've seen a few people working on various analytic projects posting there.

Another idea that no-one will use.

Will you?

Actually yes. Useful for me.

I always start out thinking others will LOVE my idea until I release it and no-one uses it.

You're a fool until you're a genius. One day I'll be a genius.
