Re: A Raspberry pi Killer. Such a wrong title.

"Raspberry Pi Killer" is probably one of the most generic promotion phrases for any single board computer right now. It's impossible to market a new single board computer without bringing up the Raspberry Pi because its dominance has earned synonymity in the public mind with SBCs like Google has wit...

Re: Raspbian Stretch Release Date?

Now that Debian Stretch is out, how long do you guys think it will be until Raspbian Stretch comes out? That recent merge of E. Anholt's work looks really promising in terms of T-tiling and moving away from compositor use - adding that compositor totally killed the stock driver for my RPi1B. Maybe t...

MSD Boot on the Raspberry Pi 1B not working?

Hey, has anyone been able to get MSD booting on the Raspberry Pi 1B (not 1B+) using an SD card with just bootcode.bin and timeout? I put the bootcode.bin on a SD card partition named /boot along with timeout, no other files. However turning this on, I didn't even get a rainbow box. Truth be told, I'...

Re: Simple battery circuit feasible?

I'm guessing you're going to use Lithium ion as well due to the 3.7V value; please don't mess around with those types of batteries without doing your research and using the necessary specialized hardware such as a charge controller. Li-ion may be common but if you handle it incorrectly in terms of c...

Re: Setting up a Pi 3 for the long haul?

You see it a lot on the internet that flash memory fails, but after doing a good deal of research I just don't think it's true on a practical level. Maybe it might have been true in the 2000s but now..? Every flash cell has a listed write limit between 1000-10,000 writes before the insulation layer ...

Re: Thinking about replacing linux box with Rpi

That is so weird. My gut guess would be that there's a physical process going on. Brief review as I remember it: flash memory works by the quantum phenomenon of electron tunneling, storing bits by changing charge state via electron transfer across an insulating layer. Flash failure happens when elec...

Re: Thinking about replacing linux box with Rpi

The only disadvantage I can see is the SD card, their lifespan can be shorter than other storage media. I will stand corrected when other more experienced Pi users express their views. I moved my files over to a $4 USB 2.0 8GB PNY Attache USB drive. About a year ago I got really into the idea that ...

Good decision. I think it symbolizes the transition from the Raspberry Pi as a toy to something more. In the past 4 years, the Raspberry Pi has advanced in application to the point where security can matter and a good proportion of its userbase is not tech savvy. It's a good sign, it's the mark of a...
