The delta of the ice on stone speed between the sides is not dependent on the rotational speed but liner speed in relation to the rotational speed.


You're wrong, and even if you were right that wouldn't argue against GP's observation.

V_cm: velocity of center of mass

V_l: velocity at left edge

V_r: velocity at right edge

R: radius of stone

w: angular speed of stone (CCW is +)

  V_l = V_cm + R*w
  V_r = V_cm - R*w
  delta = 2*R*w
Even if it was dependent on linear speed / rotational speed, the only way to change # of turns / run is to change linear speed / rotational speed.


Hey thanks for sharing. Feedback would be awesome!


I just switched from PLEX to Emby. Plex started to push Plex.TV down their users throats. Emby does not require any external authentication.

How is plex.tv, their simple redirection service, pushed down your throat? You don't need to use any of that.

I have both running, but unfortunately, the Emby server just burns resources like there was no tomorrow, and you can't really compare the UX at all, hence using Plex.


You have to use it for user authentication which Emby does locally.


That's optional. Plex has local account management. The iOS app hides it a bit, but it's there. You of course lose the plex.tv features (plex pass, etc.).


Does this support crossfire?


"Chillers" are actually direct expansion cooling devices for liquid. They have a condenser and evaporator just like an air cooled air conditioning system. The evaporator will be on the chilled water supply side and the condenser can be cooled by water or air.

The big empty box with water is an evaporative cooling tower used to cool the condenser side water.


If you use an evaporator tower you do need to replenish that water. The tower is usually used to cool a closed loop of water (or glycol/water mix depending on the climate) that cools the refrigerant in a chiller.

The system in the article uses a pipe loop underground in place of an evaporator. This uses less water/energy but require a higher first cost and very specific location requirements which is why the cooling towers are still more popular.


Larger systems can use cooling towers which leverage evaporative cooling. Also, arid climates can use swamp coolers to cool a space. They work on the same principal. When water evaporates, it pulls energy from the surrounding medium, causing the temperature to drop.


This article has a nice diagram and some explanation:

http://www.buildings.com/article-details/articleid/5757/titl...

In the discussed example, the water cooled system uses ~1/2 the energy of the air cooled system.


In CA, swamp coolers can be really great - http://www.homedepot.com/b/Heating-Venting-Cooling-Air-Condi...

I used one when I worked with a friend in LA on a car restoration project. They can generate a LOT of cooling very quickly as long as it is dry outside.


It's funny they show the northern Midwest in the maybe zone. When it is hot here, it is usually also quite humid.

Seriously... geothermal has been around for a long time.


Not really anything new...


What is the benefit of this over using a browser?


None, given that it essentially runs in a browser anyway (Electron). I suppose it's very useful if you have ~200MB of RAM and ~80MB disk space that you really want to get rid of.

I hate Electron. :-|

Oh, there goes that dream.


Qt/GTK/WinForms or GTFO!


WPF/UWP instead of WinForms and I agree. I don't even get why so many people like writing web apps, I feel a hell of a lot more comfortable working with a proper widget toolkit (my preference being GTK or WPF) without the constraints enforced on me by a browser and JavaScript.


It's because there are a lot of people here obsessed with reaching the largest possible audience they possibly can. And since every brother and their mother are on mobile, or, at least, a web browser...

The way I see it, mainstream masses are finally (FINALLY!) leaving the world of desktop computing behind, so now it can return to the nerds and people who just wanna do shit


How about new ideas like WebAssembly?


WebAssembly just makes a better target for transpilers, it doesn't really do anything to make developing "desktop" apps inside browsers easier.


I think that web app benefits vastly outweigh the constraints. Distribution is easy (give people the URL), the app is always up to date, and it's cross platform. Unless you absolutely need the features and/or speed of a device, you should seriously consider a web app vs. a not web app.


With the recent popularity of Electron, I wonder why less attention has been given to Qt Quick. The JSON-like syntax of QML as well as JavaScript should be very familiar to web developers and you get software that looks much more "native" than what is achievable in the DOM (well, without reasonable effort).


Right?! Qt Quick is faster for prototyping, at least as flexible, _much_ faster to run, still very cross-platform....

(I like Qt)


I can write my react component and use it in mobile native version, desktop electron, mobile web, web desktop. Can you do the same with Qt?

I don't get why people have so strong emotion for Electron.


I guess at the very least it'd be recognized as a separate window/app by the OS window manager, which might be convenient if you like to keep it open all the time and alt-tab to/from it.

However, at least on OS X, you can just use something like Fluid if that's all you want (http://fluidapp.com/).


Exactly what I needed. Thank you very much.


A browser is like a buggy mini-operating system that hogs resources, tries to replace native applications like PDF readers, word processors, and email clients, and uses JavaScript as its system language. Client applications circumvent the hell of modern web browsers. The benefit is not needing to use a web browser.


Wish there was some kind of a "Electron kitchen" where you could easily make your own app stating which website you want to use in this isolated way, without having to learn about Electron.



As mentioned earlier, there's Chrome's "Add To Desktop" option


Why not just run Chrome in app (or kiosk) mode?

I use this for reading my gmail. I use the --user-data-dir flag to prevent the "app" from interfering with my other browsers.


None I guess. Unless the author adds features though. But then again. What features.


Folding threads!!! The site needs them; I have a firefox addon called HN Utility Suite.
