Simple example

$ re='t(es)t'
$ [[ "test" =~ $re ]]

How to create a self-signed SSL Certificate with SubjectAltName(SAN)

After Chrome 58, self-signed certificate without SAN is not valid anymore.

Step 1: Generate a Private Key

openssl genrsa -des3 -out example.com.key 2048

Step 2: Generate a CSR (Certificate Signing Request)

This is a working example on how to store CryptoKeys locally in your browser. We are able to save the objects, without serializing them. This means we can keep them not exportable (which might be more secure?? not sure what attack vectors this prevents).

To try out this example, first make sure you are in a browser that has support for async...await and indexedDB (latest chrome canary with chrome://flags "Enable Experimental Javascript" works). Load some page and copy and paste this code into the console. Then call encryptDataSaveKey(). This will create a private/public key pair and encrypted some random data with the private key. Then save both of them. Now reload the page, copy in the code, and run loadKeyDecryptData(). It will load the keys and encrypted data and decrypt it. You should see the same data logged both times.

Porting Go to SPARC Solaris

Source: https://sysadm.life/posts/porting_golang_to_sparc/

Learn how to compile and port Go for SPARC Solaris Tue, 18 Dec 2018 label GO Solaris
This article aims to present the steps required to create a port of Go for SPARC Solaris. The ‘spark’ that kicked this idea off was part of an aspiration to first get the Prometheus node exporter for the core machine metrics running on SPARC tin for Solaris 11.3, then potentially other node exporters such as the JMX exporter and a Oracle DB exporter.

Note: Oracle announced Go version 1.7.6 will be available in Solaris 11.4. However, it seems like that 11.4 is a no go for a lot of SPARC hardware
