It's per-zone monitoring integrated into each wall-mounted space sensor. That communicates with the terminal unit supplying ventilation to each room on an individual basis. Your office building is actually a very large robot controll

I suppose it could be the difference between high rises and smaller structures. My projects have been very particular about it.

Certainly in any developed country, though I can't speak for the developing world. HVAC controls have been around basically for as long as we have been making large inhabited structures (nearly 100 years). I do this for my job in the

But virtually all buildings already do this. In fact, it's often part of the (legal) building code.

In real life this is a non-issue since all commercial buildings that have undergone any sort of renovation in the last 25 years have CO2 monitoring integrated into their HVAC control system.

It really amazes me the kind of stuff that will slide in this industry. I have seen the web front ends for the datacenter cooling systems of certain large tech companies where the password is simply password. Nobody cares much about these

Coinhive was making that much in aggregate, but the websites running their client were not. It couldn't replace ad revenues, especially after the prices crashed, and thus people ceased using it.

The performance disparity between browser-based javascript and specialized mining hardware is so large, that you will be hard-pressed to generate enough revenue to support a website.

Have you characterized the anisotropy of the fibers yet? Mechanical, electrical, or otherwise? Also thank you for the response!

How long are the continuous fibers? CNTs can do some truly insane things if you make them long enough.

I am happy to see that surrogate model optimization is starting to be used to its potential, but it's sad to have to watch it from the sidelines.

Hiring is broken because employees and employers have asymmetric bargaining power, which leads to unrealistic expectations. No amount of improved candidate screening will solve that.

If cryptocurrency is like bittorrent for finance, then this proposal is like downloading DRM-encumbered music from a walled garden marketplace. I think I'll pass.

Malicious startup idea: a company whose business model is driving rent-seeking real estate speculators into financial ruin. The company would buy residential real estate in a low cost of living area, followed by setting up offices there an

The FAST article mentions how using the ratio of short term seismic activity to long term activity to detect seismic events is prone to false positives. With this approach, you "pick" a discrete time when the seismic wave first re

It's surprising that people don't rely more on automatic arrival time picking + simple outlier rejection. It's so much more efficient than these waveform correlation approaches while being much simpler.

This is precisely why it is dangerous to let someone other than yourself decide what meets the criteria for "fake news." It gives the decider an opportunity to manipulate public discourse.

It's more than a little amusing to see this at the top of HN only a few days after getting attacked for posting my personal experience with blue light and retinal degeneration.
411.
by chroem- 8y ago
Retinal degeneration patients are all advised to avoid blue light exposure for this reason. Not only is there a great deal of research to back it up, but subjectively blue light also makes the photopsias and afterimages worse.
412.
by chroem- 8y ago
Your mileage may vary, but as someone with retinal degeneration it makes a pretty big difference. Photons in the red wavelengths of light carry less energy and put a lot less stress on the retina. Screens are pretty unpleasant for me to u

There's a very good SMBC comic that addresses the "greater pie" fallacy. [1] To summarize: the total economic pie growing and individual slices shrinking are not mutually exclusive. [1] https://www.smbc-comics.com&

The headline's premise of censorship seems a little bit hard to believe, considering the nonstop media circus surrounding the president.

I don't think you would even necessarily need stages if you don't have any empty fuel tanks to discard. The engines might not be as optimized for operating both in and out of atmosphere, but that seems like a fair tradeoff.

Polyethylene is more or less inert under atmospheric conditions.

This is pretty neat. It would make staging and reusability a moot point if the entire launch vehicle was an engine attached to an expendable fuel rod with a payload adapter on top. You could recover the engine fairly easily since it'

For context, I posted an algorithm that's about 1000x faster than the state of the art on HN a few months ago as an open source project to solicit job offers, and I know at least a few companies are using it in production. I got quite
