Remote, Office not Required https://basecamp.com/books/remote

1. If I can't see them, how do I know they're working?

(pg 54) People have amazing ability to live down to low expectations, or live up to high expectations. If there are trust issues with employees, then the employer made poor hiring decision. Employer/Employee trust is fundamental.

2. People’s homes are full of distractions

(pg 58) being easily distracted from work could mean the work is not well defined or the task is menial, pointless. Might be a chance that if someone feels like this, others on the team might feel the same.

Vpn-ception

Ideally, I like to run one vpn. I have OpenVPN/PiVPN working just fine.

On the PiVPN server, I'd like to run a VPN client to my work office.

It's difficult to get Cisco VPN client and Tunnelblick clients running side-by-side on the same machine, ie my local dev machine, without a seeming hack(see below).

I have it working locally.

• Cisco AnyConnect Client connect to work VPN. Only specific resources are made available. All other traffic is routed as normal.

trim an mp3

I record mp3s from a few streams. Sometimes the recordings do not stop on schedule. This command allows me to trim or trucate the mp3 file.

ffmpeg -i infile.mp3 -vn -acodec copy -ss 00:00:00 -t 01:00:34 outfile.mp3

installation on ubuntu 14.04
