    Are passive phase change cooling systems sensitive to tilt, movement or vibration?

    Posted: 01 Mar 2020 01:02 AM PST

    So we're starting to see more and more passive phase change cooling solutions for computing. Here's a LTT video showing one, here's another. When I saw these I thought they'd be great for stuff like the powerful computers needed for self driving cars or trains since you eliminate a pump which could be a point of failure, and the fact that it's passive means you're saving energy on the cooling solution. Just curious, are the performance of these systems hampered by things like sudden movement or vibration? Or even things like tilting the system? I know you can't flip them upside down, but how sensitive to movement and orientation are they?

    Why has mobile power efficiency gone backwards?

    Posted: 29 Feb 2020 07:36 PM PST

    It seems like I'm not the only one puzzled by why 3G, 4G, and I presume 5G suck considerably more battery life than 2G.

    As a quick example, the nokia 2630 had a 700mah battery, and the talk time was up to 6 hours.

    The palm phone however, says up to 3 hours and 20 minutes talk time, despite an 800mah battery. The 'standby time' is up to 96 hours (altho official website says 72hrs+), yet the 2630 standby time was rated at 310 hours.

    Palm phone in 'life mode' aka 'flight mode' has "over" 168 hours before it dies.. Which is just ridiculous when you see that 2G phones can stay CONNECTED for waaaay longer, where as palm phones cant even last as a dumb brick.

    I saw a pretty big increase in battery life on my nexus 5 using 2G/edge, without using any calls, texts or data, and staying connected to wifi, compared to allowing the phone to stay on 4G with wifi. Just the standby on 4G is a huge drain compared to 2G.

    I also saw much better battery life when out and about on 2G, compared to 3G and 4G. Didn't even matter if I was using the 256kbps edge connection pretty hard, it still was easier on the battery.

    If 3G, 4G etc signals are more complex and require more processing on the phone side, how is that still an excuse by now? Mobile processing power has advanced a ton since 2007, so why can't we yet match the standby connection times of 13 years ago on modern mobile networks?

    Are we ever going to be able to achieve what Nokia phones 13+ years ago could do, with similar standby and talk time per mAh?

    Is virtualization context itself and switching between them costly?

    Posted: 29 Feb 2020 08:59 AM PST

    Recently, I've got an idea, like "what if every thread had its own VM context, so it just can't do any malicious job". Will hardware perform well in such case?
