Fwiw, there is an established community of people experimenting with underground homes in the western United states. These are places where folks actually live and the curious can rent for a short term. https://earthship.com/

Earthships are not underground. They have one wall that's stacks of old tires, with an above-ground dirt mound against that wall, and sometimes dirt on top of some of the roof (but mostly not).

Sigma is a BI system with a visual manipulation interface for query construction (Workbook) that has similarities with Ultorg.

The Sutter Hill website[1] is mysterious. Like they are in stealth mode.

They don't really need a website. Most VCs operate under the assumption that "if you are resourceful and connected enough to get introduced to the people you'll need to make your company successful then you'll find a way to get introduced to us."

I really admire the way that Chris and his team were open about their ideas and their journey. They inspired me and I'm sure many others through this. Thank you Eve.

Sigma Computing | Software Engineer, Front-end | San Francisco | ONSITE | https://sigmacomputing.com/careers

Sigma Computing is an early stage startup building a new interactive analytics and visualization system. We are a small team of veteran programmers attacking hard problems in human-computer interaction. We're making databases and data warehouses usable by non-programmers.

We're looking for strong computer science fundumentals, a track record of building and maintaining complex JavaScript front-ends and a desire to be a great teammate and have fun at work.

Very interested in the role! But the e-mail provided didn't seem to work for me - is there another e-mail we should try?

Thanks for the interest. Emails seem to be flowing, but you can also contact rwoollen@sigmacomputing.com directly.

Layer (http://layer.com) is building a successor to XMPP that's optimized for mobile and solves device coordination problems. The inventor of XMPP, Jeremy Miller, works there.

This looks interesting. I looked at their site and documentation for implementing a client (once they are up and running). Do they provide any other information about their goals? Do you know if they have a goal to let anyone run a Layer server with interopability like xmpp does?

Ahh.. found their blog.

The pahole(1) utility, mentioned above.

Haskell was excluded from this benchmark because I can't figure it out.

Take the code here: https://github.com/logicchains/levgen-benchmarks/blob/master... and run it. Then, take the same code, change the genRooms function to contain:

  where

    noFit    = genRooms (n-1) (restInts) rsDone

    tr       = Room {rPos=(x,y), rw= w, rh= h}

    x        = rem (U.unsafeHead randInts) levDim

    y        = rem (U.unsafeIndex randInts 1) levDim

    restInts = U.unsafeDrop 4 randInts

    w        = rem (U.unsafeIndex randInts 2) maxWid + minWid

    h        = rem (U.unsafeIndex randInts 3) maxWid + minWid

And change:

let rands = U.unfoldrN 10000000 (Just . next) gen

to:

let rands = U.unfoldrN 20000000 (Just . next) gen

The running time should double. Does it? Or does it increase by orders of magnitude? The latter is what happens to me.

I just changed the random number bit, not the 10000000 part, and it took ~100x longer. No idea why.

Maybe a compiler bug?

I'm a total noob to haskell and I'm not sure I understand the code well enough to ask an intelligent question about it, but I'd love to see you/someone ask on the haskell mailing list/stackoverflow/reddit-haskell or something.

I'll post a question on Stack Overflow then when I have time.

Ease of use matters.
