comment What is the purpose of this 4 pin cable with 3 wires that came with an old IDE DVD-ROM drive?
I have a bunch of these old cables laying around, they're quite handy as patch leads for Arduino projects (e.g. connecting a serial LCD to Arduino). :)

comment Mac : How to enter the full directory path in a save As Dialog?
Typing a single forward slash (as one would to begin an absolute path) will generally also display the go to folder sheet. The forward slash will be included in the text box, so you can just keep typing.

comment What are the best proxy servers for Mikrotik router?
The masquerade action is a MikroTik-specific option designed for convenience (it automatically selects the public IP); you can use the src-nat action to do the same thing, but you'll need to manually specify the public IP.

comment Digital ID for internal communication
Despite my answer, I'd really suggest looking into establishing your own internal CA—even for only three or four users. Firstly, you'll only need to install one certificate on all machines, instead of three or four; secondly, three or four easily becomes eight or ten in six month's time and a solution like this can easily get out of hand. Having a CA also lets you revoke certificates when people leave, lose their key, etc.

comment How to properly setup openssl CA to generate ssl client certificates
I've taken my best stab at an answer below, but if you can include a copy of the output from openssl x509 -text -nameopt multiline -certopt no_sigdump -certopt no_pubkey -noout -in one_of_your_client_certificates.pem and the extensions section from your openssl.cnf file, I'll see if I can provide more specific advice.

comment Can self-signed SSL certificate be renewed? How?
@FriendFX Yes, that tutorial will only work for self-signed CA certificates. If you use the same key pair and subject, you can create multiple CA certificates that will each satisfy as a valid issuer for issued certificates; these certificates can even be issued by different parent CAs, which is called "cross-chaining".
