Re: Will adding an external SSD speed up Raspberry Pi?

have not tried adding an SSD drive to a microSD boot setup, as I have migrated from microSD boot to USB boot (thumbdrive/HDD/SSD) on my RP2B v1.2, RPi3B, and RPi3B+ units. As boot drive SSD boots a bit slower however, system responds better after that (if this is the same as " speed up " in your mi...

Re: I want to do this, what programming languages and libraries do I need to know?

You said you want some user input for a time interval and then to alternately connect to two wireless networks. It's very doable in shell. POSIX is the least common denominator variant and the most portable. #!/bin/sh read -p "interval in seconds: " s; while true; do echo Connecting to network 1 # ...

Re: I want to do this, what programming languages and libraries do I need to know?

The simplest would be to do it in POSIX shell script, the next simplest would in Bash shell. Above that, python, perl, or similar would work but be more complex. I'm hearing about POSIX for the first time from your comment. I'm unable to find any resources for POSIX or BASH. Do you really think wha...

If you do not know any programming language, Python is a good start. If you actually are fluent in any other programming language, why don't you use it on the Pi ?

Is there a way to fsck run on boot if there is an unclean shutdown.

In Windows if there was an unclean shutdown, scandisk would at the next boot.

Can something like that be set in Raspbian? Like make fsck to run on boot and check the boot and root partitions for errors and repair them.

Cutting power without safe shutdown can corrupt data on the SD Card, it is well documented,. If you have constant power cuts you should invest in a UPS.
But now the Raspberry Pi is having trouble even with a newly imaged SD card.

Re: Is this a Raspberry Pi problem or SD card problem?

Could be a card problem or a problem with your card reader. Try the SD Memory Card Formatter from the SD association, or use Disk Management to remove all partitions and re-initialize the card as a simple volume. I tried this through at least two ways, 1. Through USB card reader 2. USB hub's card r...

If the green led never comes on when you apply power then the RPi hasn't been able to read the files in the boot partition.
