Checking your Raspberry Pi's view of its power supply

Sometimes it seems like the first (and sometimes only) advice you get offered for almost any problem with a Raspberry Pi is "check your power supply". You think something like:

"hey, I'm using an official power supply sold as being matched with my Pi so how can there be any problem?"

You look up the specs then stick a controlled load across your supply and confirm that it can deliver the required number of Watts.

Yet your problems persist…

Get the (readable) certificate from a windows executable (PE)

From: http://web.fournier.nl/2013/10/get-readable-certificate-from-windows.html

I searched high and low for a simple (linux) solution on how to extract the certificate of an authenticode signed windows binary. I don't want to use wine, nor mono. This is what I came up with:

• Extract the certificate with 7zip: 7z e setup.exe CERTIFICATE
• remove the first 8 bytes: dd if=CERTIFICATE bs=1 skip=8 of=setup.exe.pkcs7
• Read it: openssl pkcs7 -in setup.exe.pkcs7 -inform DER -print_certs -text
