Teaching Coding like a game
How can we trick our brain into liking what we're learning?
Guess what, you can’t . Not really but kinda.
What Mark Rober here is trying to explain is that if we can frame our learning in a way that the goal is most desirable, then we can teach our selves new things.
One of the key takeaways from this is learning without fear of punishment. How can I incorporate that into my teaching style when the one of the main tenants of our education process is being graded? Perhaps I need to phrase my grading differently, instead of deducing points for mistakes, it should be worded as awarding points for a job well done.

Difference Between DER and PEM Certificate Encoding
There are two main methods for encoding certificate data.
- DER = Binary encoding for certificate data
- PEM = The base64 encoding of the DER encoded certificate, with a header and footer lines added.
DER
DER: (Distinguished Encoding Rules) is a subset of BER encoding providing for exactly one way to encode an ASN.1 value. DER is intended for situations when a unique encoding is needed, such as in cryptography, and ensures that a data structure that needs to be digitally signed produces a unique serialized representation.
PEM
PEM: (Privacy-enhanced Electronic Mail) Simply a US-ASCII by base64 encoded DER certificate, certificate request, or PKCS#7, enclosed between typical PEM delimiters. ie “—–BEGIN CERTIFICATE—–” and “—–END CERTIFICATE—–“. PEM is an abbreviation for Privacy Enhanced Mail (RFC 1421 – RFC 1424), an early standard for securing electronic mail (IRTF, IETF). PEM never has been widely adopted as Internet Mail Standard, but has become a staple standard in x509 pki (also called pkix)
Certificate naming extensions

Add Certificate to JAVA keystore (cacerts)
Requirements:
- Have keytool installed (Installed as a part of the jre)
- Have your certificate local (either pem or der format)
- Know where your keystore is
