Re: Raspbian refuses to use Swap Space

Well, I have now installed Gentoo 64Bit on the Pi and it has gone a lot better. I can now actually use the full 4GB of memory. It also allows me to go deep into swap space. 8GB on an external harddrive. Still bombs on larger datasets. Will wait for the official 64Bit launch of Raspbian and try agai...

What's a Pi 4? 20 watts maximum? That's $50-$100 a year in electricity. Peanuts for 24/7 usage of a device

Re: Am I the only one that still would buy a Raspberry Pi 3b+?

Aren't they the same price as the Pi4B1? If so I'd never get the weaker one barring some business reason of some incompatible attachment or program.

Así use Pi personally I'd never order an older one. I have Pi 1-3Bs btw and plan on ordering a 4B4

Re: RPI4: Why is everything still 32-bit?

My plan is to win Powerball, buy the Pi foundation and force deprecation of 32 bit. If so many people love it let them maintain it while the supported OS goes 64 bit.

Actually I'd probably just use the money to make a RISCV board

This post is 100% humor

At 1080p it takes about 8MB, and 720p only 4MB. Shame there isn't an option for text only consoles to only give the GPU 1-2MB of RAM.

Re: how to increase ram

Did they ever reenable zram in the kernel? iirc they disabled it a while back for some reason.

Re: Damage if using 4xAA NiMH?

I've been contemplating getting a lead acid battery and switching regulator to power my pi. Build it all into a medium sized plastic or metal case and just add connectors for the charger/power supply externally(or build it in). Less hassle in the long run than fumbling with multiple separate NiMH ce...
