the mechanism of it is not that paper is saturated with water, but that while there is water in the container, paper doesn't get hotter than 100C and a bit, not enough to ignite.

New comment by alecmg in "UK to finish with coal power after 142 years"

alecmg — Mon, 30 Sep 2024 11:30:44 +0000

Could it be quantified how much UK is using coal power of other countries?

Since industry is moved outside, the products we consume use power of producer country, mostly China. Is there a correlation in reduction of local coal power and amount of energy intensive products imported?

I WISH it would be prefetching video in background while showing ads.

But no, always goes to spinny wheel buffering after ad ends. Oh, and thats after having some spinny wheel to load the ad in first place ffs.

> The new 4K 32" 3rd gen QD-OLED panels seem to be the closest to perfection, but I'm not sure if they're suitable for long sessions of programming, web browsing and reading documentation (i.e. displaying static UI elements for hours) due to burn-in and temporary image retention.

Wouldn't worry about burn-in. 3rd gen should be more durable and equipped with all kind of burn-in mitigation tech. And a 2-3 year burn-in warranty

My concern about OLED used to be the weird pixel layout, not great for text. But on 4k QD-OLED pixels are smaller, so text fringing is not noticeable. And LG WOLED coming this year should have no problem at all.

Not an issue if they have a means of propulsion capable of delivering 1g the whole way

Which is necessary to go any meaningful distance in space anyway

ahh, I wish they included speed comparison to numpy.average

I know, thats not the point and average was only picked as a simple example, but still...

I saw comments that if introduced together with Faster CPython single thread performance optimisations, nogil would end up no slower than previous version. So it is best time to implement

maybe its a reference to Amdahl's law?

If you can parallelise 90% of your code, you get only 10x improvement even on infinite number of cores

New comment by alecmg in "Two Mice Technique"

alecmg — Fri, 02 Jun 2023 11:28:44 +0000

Started getting RSI symptoms in right hand years ago. Mainly from heavy gaming, but I needed to use mouse at work as well so right hand was not getting any rest.

Switched to using mouse in left hand for work, right hand for gaming. Never looked back. Turns out mouse motorics are almost independent from human handedness.

To comment the article, depending on OS and mice, you will have trouble assigning different orientation to different mice. Usually if you want left hand mouse to have index finger "left" click, it will also switch your right mouse... and trackpad...

I think Windows is even more permeated with legacy

Off the top of my head:

Nobody questions why main drive is C:, remnant of [an] early computer having two floppy (not sure) drives on A: and B:

Or more recent - C:/Windows/System32 holds 64 bit executables; 32 bit exectuables live in C:/Windows/SysWOW64

Its ironic and scary how 3.11 was the last Windows with consistent

a) UI design. It was either a DOS box or a Win 3.11 style window

b) file sharing, simple and intuitive

c) integration with browsers. Browser was standalone. There was no integration.

We were getting 1000km between fill ups (60L tank) on a family road trip in a bog standard 1.8L gasoline (!) Ford Mondeo, seating 2 adults 2 kids and with trunk loaded to the brim and A/C running on full.

Really difficult to be excited or impressed by these "records". Both Tesla and H2
