Do you speak native Linux and have operations experience with a large server cluster?
Are you enthusiastic about systems automation (we love Puppet, Chef or CFEngine experience will also give you the right philosophical background)?
SlideShare is looking for dev-ops engineers who will be responsible for scaling SlideShare to hundreds of servers, using automation, virtualization, and cloud computing technologies like Amazon EC2, SQS, S3 (which we use extensively).
We don't believe ops should spend all day firefighting and doing chores to keep the system healthy.
We believe ops should create valuable intellectual property the way software engineers do, using tools like Puppet, MemCached, Varnish, TokyoCabinet, HAProxy, Nagios, Cacti, Ganglia, and MySQL
A Note On Practice And Persistence - Python developer
While you are studying programming, I'm studying how to play guitar. I practice it every day for at least 2 hours a day. I play scales, chords, and arpeggios for an hour at least and then learn music theory, ear training, songs and anything else I can. Some days I study guitar and music for 8 hours because I feel like it and it's fun. To me repetitive practice is natural and just how to learn something. I know that to get good at anything you have to practice every day, even if I suck that day (which is often) or it's difficult. Keep trying and eventually it'll be easier and fun.
As you study this book, and continue with programming, remember that anything worth doing is difficult at first. Maybe you are the kind of person who is afraid of failure so you give up at the first sign of difficulty. Maybe you never learned self-discipline so you can't do anything that's "boring". Maybe you were told that you are "gifted" so you never attempt anything that might make you seem stupid or not a prodigy. Maybe you are competitive and unfairly compare yourself to someone like me who's been programming for 20+ years.
Whatever your reason for wanting to quit, keep at it. Force yourself. If you run into an Extra Credit you can't do, or a lesson you just do not understand, then skip it and come back to it later. Just keep going because with programming there's this very odd thing that happens.
At first, you will not understand anything. It'll be weird, just like with learning any human language. You will struggle with words, and not know what symbols are what, and it'll all be very confusing. Then one day BANG your brain will snap and you will suddenly "get it". If you keep doing the exercises and keep trying to understand them, you will get it. You might not be a master coder, but you will at least understand how programming works.
If you give up, you won't ever reach this point. You will hit the first confusing thing (which is everything at first) and then stop. If you keep trying, keep typing it in, trying to understand it and reading about it, you will eventually get it.
But, if you go through this whole book, and you still do not understand how to code, at least you gave it a shot. You can say you tried your best and a little more and it didn't work out, but at least you tried. You can be proud of that.
