You can either post a message or email me at grant sofastatistics. The latest version takes a further step in that direction by integrating on-line help into all the statistical tests. Integrated on-line help for statistical tests. Version 0. The other change is that passwords are now hidden when configuring database connections in projects. There has been an important bug fix for a problem introduced in 0. Or talk one of your coworkers into it. Better yet, do both! LISA can only remain a great conference with your participation.

Fear, uncertainty, and doubt FUD is often used to undercut the use of open source solutions, particularly in enterprise settings. They clearly label it and it takes money to run a website. Linux Journal pays writers and that money has to come from somewhere.

But this particular article was tragic. The most common use case is to allow administrators to run commands as the root user, but it can also be used to give, for example, webmasters the ability to restart the web server without giving them full access. Erbe argues that using sudo adds administrative overhead because you have to maintain the configuration file. I have seen sites that use commercial solutions to replace sudo, and they still have to configure which users are authorized to use which commands on which servers.

Erbe says configuration management systems can repair modified configuration files, but with a delay.


It logs every command run and who runs it. Putting a key logger in it would provide no additional benefit. The applications launched with sudo or the operating system itself would need it. Except that you can, in fact, downgrade the sudo version if it contains a critical bug.

And you can get commercial support. Not for sudo specifically, but for your Linux installs generally. This sems like a repeat of the last point, with a different focus. How many products developed by large commercial vendors have security issues discovered years later? A given package being open source does not imply that it is more or less secure than a proprietary counterpart, only that its source code is available.

Erbe raises some good points, but loses them in the FUD. Instead, all we get is someone paying to knock down some poorly-constructed strawmen. I dislike the article for a variety of reasons, but I want to focus on why the core argument is bunk. AWS offers dozens of services for computation, storage, and networking that roll out updates to datacenters across the globe many times a day.

DevOps practices are what make that possible.

Shut up. At the end of the article, the author finally gets around to admitting that DevOps is a cultural paradigm, not a position or a particular brand of fairy dust. They needed someone to look at Linux developer tools, and especially the open source tools to see which ones were worth spending time on. Since I had used open source tools and had a UNIX background, they threw the project in my direction.

A huge part of the evaluation was related to the community. Is there an active community? Are there regular releases? Are there users for the tools? I started to get more and more fascinated with how the communities worked. When I first started using open source, how a bunch of random people threw code together and actually ended up with something not only worked, but worked really well was a mystery to me. Even if you have already have one of these jobs, this talk will provide options for additional career paths and tips for what to do improve your chances of getting that next gig and how to avoid sabotaging your career.

A lot of my friends are people that I met in open source communities around the world, and I often use travel or vacations as an excuse to visit them. Werewolf is one way, but there are also people that I spend time hanging out with over dinner, drinks or other conference activities that I stay in touch with. This is me giving a talk at the MeeGo Conference in Dublin.

Not everyone who works in open source gets to travel, but I think that we have more opportunities to travel than many of our peers who work on proprietary products. There is a lot of Conference travel with events like the kernel summit, KDE Akademy, other gatherings of developers for the open source projects. We do Puppet Contributor Summits for project developers twice a year, once in Europe and once in the US at our annual conference, but we also do Puppet Camps for users around the world. These are great opportunities to meet the people that I interact online in real life.

Part of this is because we are working on open source projects, so we can talk openly about the work that we do. Attending and especially speaking at conferences is often encouraged by employers who want people to know about the work they are doing. It also makes it easier to hire people. If you work at a big company, there is often company travel where they send you to places like South Korea to work with other companies that are working on the same projects.

When someone is interested in hiring you, they can Google you and see all of your participation in these open source communities. Being able to see actual examples of your work is way more useful for hiring managers than reading a boring resume. Working in open source projects also allow us to make connections with people whose companies are hiring from the community. This is especially true of Puppet Labs and Intel.

I love the fundamental ideals behind open source software. I have the freedom to use it, to inspect all of the details, make changes to it, and to redistribute it as I need to without getting permission from anyone else. As a result, I think that we end up with software that is innovative and interesting, and we get to work collaboratively with other people. The hard way might be one of the most rewarding ways to make a career out of open source, but it requires building a company around the technology, and that can be hard work.

This is a much easier path than starting a new project, and this is probably the most common way to turn your open source work into a job. We did this when I was at Intel, and we do it now at Puppet Labs. This is one of the best ways to get your foot in the door with an open source job. Not unlike companies, open source projects need people to do all kinds of things. Someone needs to write the blog posts, do documentation, promote the project, and so much more. Another good way to start your open source career is to work for a company that does a lot of work in open source software.

You can join one of these companies in all kinds of different roles: writer, marketing, system administrator, developer, lawyer, and so much more.

This is how I first turned open source into an accidental full-time job. Open source tools were really the only option for me. Some of my most interesting opportunities have come about as a result of my writing and speaking. My first full-time community manager gig landed in my lap when Larry Augustin and I were both speaking at a small open source event. I was talking about community, and he was on the board of a company who needed some community help.


When I was consulting, a lot of my work came from people who had heard me speak at some point often years earlier or who were reading my blog. Your interactions within the community will live forever.

I continue to run into the same people in different communities, and you never know when you might end up working with or even for that person that you are interacting with online today. Networking is another key to increasing your chances of being successful. This is true if you are looking for a new job in open source or just making the best of the job that you have now. When you are looking for a job is not the time to start networking. This needs to be more long-term and something you should be doing all the time.

I recommend approaching it as having conversations with people that you find interesting. If someone is boring you to death, you should make a nice, graceful exit and find someone whose work is more interesting to you. Talk to a wide variety of people and learn more about what they do. Personally, I love hearing stories about how people ended up working in open source and hearing about what people are working on.

Finding the right balance between doing as much as you can, while not pushing yourself past your limits is something that I constantly struggle with. I always want to help out and do everything that I can to make the project successful, but there is only so much that I can do. I try to be brutal about which tasks I need to focus on because they are the most important, not necessarily the ones that other people think are the most urgent.

I often wait to respond to requests or questions in hopes that someone else will respond. This works more often than you might expect, but it does mean that I often have to look at thread later to make sure that someone responded. Waiting also has the side effect of giving others the space to contribute. Most of us fail at documentation at some point. I know, I know, no one wants to write documents. It takes precious time, but it can save you so much time in the long run.

Documenting processes and procedures for the project is also what allows you to more easily delegate tasks. I have tons of email templates and canned responses floating around. I use canned responses as the start to my answer when I get those common questions.

I usually customize it a bit, but the basic idea and usually a few links to more info are mostly the same.
