That seems to be for a 2006 Daikin model: > The heat pump model is based on linear interpolation in a performance map retrieved from manufacturer data (Daikin Europe N.V., 2006). And that model is half as good as the modern one I linked:

Here's a current R32 system by Daikin: https://www.daikin.co.uk/content/dam/dauk/document-library/d... SCOP is at 5.15 and that's a seasonally adjusted value. So over the entirety of the winter

The explanation of needing to pre-heat the air into the heat pump is strange. Modern A/C systems can pump heat at 500%+ efficiency even with very cold outside temperatures, no pre-heating needed. Replacing that with resistances is a 5x

Uncontained engine failures are cause to ground whole fleets of planes, even if the resulting emergency ended up mild. You're downplaying it way too much.
338.
by pedrocr 6y ago
Uncontained engine failures are a big deal. Exactly because they're a risk to the plane, as debris can cause other failures, and a risk to people on the ground. Engines are specifically tested to see if they can contain these failures.

Yep, the no-panic crate is the hack I mentioned. It's using the linking process to fail compilation if I remember correctly. It only works on individual functions. rustig I didn't know and looks very interesting, thanks. Having it

Rust also has the traceback/exception error handling mode in the panic cases. And since there's no standard way to check those at compile time you're left to fuzz the code to find all the possibilities (or use some hacks). It

If I didn't screw up the math that would be ~7% of UK's 2020 GDP and around 60% of the GDP loss in 2020 compared to 2019. It would be really expensive but the scale of what's happening is also huge. So maybe not the greatest

Ubuntu LTS already has the hardware enablement stack to solve this very issue. You stay on the LTS but get newer kernel/mesa/etc for hardware support.

That would seem like a great defense if it was the algorithm making a choice on what to promote. But they're apparently actively removing the content. There doesn't seem to be any reason for that in their model.

Only if the app is broken. The rendering engine needs to be able to fill whatever pixel size at whatever scale. If you mean that you can no longer do 2x and scale down at the exact perfect scale then that's true, but only a limitation

Quite the opposite. Once you push the problem to the client a lot of them already know how to do it and by not doing two scaling steps you can make much better decisions. And you don't need coordinates as floating point at all. What yo

by pedrocr 6y ago
It's not how it works at all for fractional scaling, which is the point. And you don't give it a 133.33 box. That's what you're in effect doing now by having the compositor scale the whole screen. You give it an actual 1

It would actually be great if Wayland would allow clients to handle HiDPI themselves but it doesn't which makes fractional scaling much worse than it needs to be. Wayland defines integer scaling only and then compositors scale 2x conte

Calling it impossible to flip votes is quite silly. You can just pre-program the machine to pick a candidate randomly every few votes and you skew the election. Do it after the first few votes to give you a distribution so as to only do it
