Not too late. You have a good foundation to build upon. Just need to pick one of several possible directions:
* system admin -- your linux background is impressive, but need to pick up windows admin skills (most small shops require both), firewalls, proxy servers, caching, CDN
* front-end coder -- learn Javascript and related technologies (jquery, Node, requireJS, browserify, handlebars, etc)
In addition to freshening up skills, do some networking through meetups. Also flesh out your online presence. Have an active Github profile. Also Stack Overflow. Check out TopCoder.
Lastly, lose the "OldCoder" label. You can only get away with that if you are Kernighan, Ritchie, Guy Steele, or Dave Cutler.
