All kinds of certifications available for this kind of thing. Sys admin in enterprise networks shouldn't be too hard to find training courses for. You will some hands on for sure but I would think a large portion could be learned online.

Interesting.

Well, not necessarily 9k over 12 months. It's 18% of first year's income, with a guarantee of a 30-50k job within 2-6 months or you don't pay tuition (plus 2k down is refunded)

Since it's the same guys who did Odin, I assume some critiques and addon guides like this still apply to Viking.

in my opinion, you should focus on building skills first. I'm not sure if there are OS or networking online courses online for free but I assume there are. I think you should do those first. use linux every day. when you need to install something, install it from the source. build those underlying skills so (1) you find out if you're passionate about it (2) if you're not passionate about it, your skills are transferrable, (3) if you do eventually go for a paid program, you'll be in position to maximize your retention and be at the top of your class since you'll have already seen some of the material (it takes me 2 or 3 times seeing these things to really learn them)

build skills first, then specialize. if you specialize first, you're become a one-trick pony and won't understand the broader world around you.

excellent point

One thing I might add is to learn the CLI version of whatever software you're using. For example, you can use Jasmine for unit testing in Javascript (have to open up html page to run tests -- gui interface) or you can use karma-jasmine which allows you to run the tests in CLI (some setup may be required ).

Computer science for Data Sciences and Cyber Security. Given your background in statistics, these are relevant.

As mentioned above, self learning and short courses are more than enough for web dev, network admin and QA.

Also take into account that self learning is the required coreactivity no matter what path you take.

If you want to get a job that includes as much of these fields as possible. You could develop server side for most websites with recommendation services. Basically any social network,( matchmaking websites, facebook, video services.)

You are not going to be a system admin along with those unless you wind up in a startup company with a small amount of employees and become some kind of tech handyman.
" Oh great, you solved NP=P, now could you clean my computer? It has viruses."

Of these 5, QA is the easiest to get into because it requires the least pre-requisites. You need a certain mindset to be a great tester. Mostly curiosity and a desire to break things.
