Experimenting with ways of having automatic memory management without either traditional garbage collection or reference counting, but rather by finding proofs of nonliveness at compile time. Trying to find under what language restrictions such a thing might be possible.

You may already be aware of it, but sounds something along the lines of lifetimes in Rust:

A malloc implementation: https://github.com/andrewf/scarymalloc . The idea was to have a simple, low overhead implementation that still has the potential to be performant, not that I've gotten around to benchmarking it. I'm working on a leaner system of headers where the free-list pointers are stored in the payloads of free blocks instead of the bodies, and the footer of one block is the header for the next (if there is one).

Nice. I'm trading delta-neutral, volatility strategies on options using Interactive Brokers API. Right now trade entry is automated, but I do adjustments and closing trades manually. I spent a lot of time on tech, digging deep into C/messaging queues/distributed backtesting/event processing but I think best to use Excel instead of worrying about tech.

Good stuff. I might need to work with you to get mine working!

Nah, bro. Unless you want help on how to lose money on the market and also give more commission to your broker. If you're in the right area, they have Algo Trading meetup's or regular trading meetup's where some peeps maybe do algo-trading. e.g.,

Already have hundreds of beta signups waiting.

I spend about 90% of my time working on Improvely ( https://www.improvely.com ) which is doubling in customers/revenue every few months. Next month I'm going to be wrapping up a bunch of major features that have been on my TODO list for a long time which will be pretty neat. I also run W3Counter ( https://www.w3counter.com ), a couple e-commerce stores, manage two more e-commerce stores for relatives, and have a few…

Funny running into you here! I use your Bootstrap date range picker for many of my projects and I think I tweeted you a while back. Really happy with the BS3 update and good to see you in the HN melting pot, thanks again.

I've been working on a web-based remote management system for controlling and monitoring industrial systems such as plant rooms, cold storage, orchard irrigation and dairy farms. We're based in New Zealand and very near being approached by a multinational for inclusion within their products (farm solutions). Things like turning pumps on and off, getting SMS alerts, user management etc.

I used Bootstrap 3 to take away the load of developing a native app for each platform and as of this weekend I've been working on a replication scheme which should get our command delays down to within a few seconds. The next process will hopefully be to eliminate PLCs and get Arduinos or similar hardware involved.

A similar face in this thread is dangrossman, who created the awesome Bootstrap date range picker that's plastered all over our graphs and historical reports.

Unfortunately it's still very much in beta and I have contractual obligations so I can't you a full tour but the marketing page (WIP) can be found here: http://concar.co.nz/services/rms/
