My dad was placed in a high-tech job skills program after being laid off by his previous employer. He now has his A+ and Network+ certificates. Using basic terms with him like "CAT-6e cable" he still has to ask questions like, "you mean the yellow wires?" All things fair, he still muddles through his own problems now (which is a relief to me) but I think it speaks volumes how much a certification is actually worth.
Normally, I'd advise you to use your resume to show potential employers that you've done hard stuff and use your cover letter to point out the holes you're especially good at plugging (e.g. I, personally, tend to make tools that make tedious, manual, error-prone tasks a few clicks or a single command). However, since you're doing the freelance website thing, I suggest that you ask your satisfied customers to write referrals for you that you can reference. If you have an especially good, ongoing relationship with a particular customer, offer them a discount to take phone Q and As with potential new customers. In short: Network.
More money down the shitter. I can't think of anything a hacker would gain from a medical device.
Things like record keeping blood bank software is regarded as a medical device by the FDA. Such software can contain sensitive information like you Social Security Number or drivers license number. In Sort, a hacker can gain plenty from breaking into a medical device.
Speaking as someone who has worked in the software side of the medical industry I just want to say that this is long overdue and the FDA has their work cut out for them. The systems I worked on are laughable in their "security" as they typically rely on how secure the local intranet is. Software vendors rarely put in any kind of serious authentication methods.
Journalist Arrested For Tweet Deported to Saudi Arabia
Right. Okay. Uhm. How do you deport a tweet?
I remember when Alta Vista came out with natural language searches. You could ask it What's the name of President Clinton's cat? And it would give you links for where to buy sock fetish porn.
There. Fixed that for you. No, seriously. I'm not kidding.
First, disregard all the posts calling you a douche. If you're unhappy in your job, you're unhappy in your job. Anyone criticizing you for a 1 paragraph ask
More on-topic, most major trading firms (at least the ones in Chicago) are heavily Linux/Unix based shops who are more interested in using tools that can get stuff implemented *now* (usually to fix an issue) than tools they have to negotiate a price on and implement in the next month or two. Obviously enough, however, this is only one side of the open-source coin. If you want to do more than just *use* open-source software and you want to be part of a company that is actively building and developing open-source tools, then I suggest you target specific companies like RedHat or specific roles in companies that own major open source tools. Most companies have job postings somewhere on their site, so if you target the right companies and sell yourself in the right way, you should be able to find a good fit.
If all else fails, lower your standards.
