This post is kind of like “part two” on my series on all the weird things I do for my personal infrastructure. If you missed “part one”, you should check out Home Lab is the Dopest Lab.
I run a lot of little things to make my life easier, like a CI, some bots, and a bunch of services just for the lolz. This post will go over all of those.

I always have some random side project I am working on, whether it is making the world’s most over engineered desktop OS all running in containers or updating all my Makefiles to be the definition of glittering beauty.
This post is going to go over I how I recently redid all my home networking and ultimately how I got to here:
ssh-ed into my dev NUC from a Pixelbook 39,000 feet, authenticated from an ssh key on a yubikey, the future is dope AF

I recently started a job at Microsoft. In my first week I have already learned so much about Windows, I figured I would try to put it all into writing. This post is coming to you from a Windows Subsystem for Linux console!

I recently gave a talk at DevOps Days (slides) and it had a pretty great response. I’m still pretty care-mad about the topics it covered so I figured I would turn some key points from it into a blog post.
The overall outline of the talk covered the past, present, and future of usable security. Let’s start with the past.
The Past A lot of the security tooling of the past (that we still use today) require users to jump through a lot of hoops or learn a hard to grok interface.

I figured it would be nice to have one canonical place for talks I have given on containers, container security, Docker, Kubernetes, and Open Source. So here it is…
2017 Google Cloud Next - Build user trust: running containers securely Co-Speaker: Alex Mohr
This talk covers all the ways you can secure your Kubernetes cluster using a Certificate Authority, Authentication, Secrets and more. We also describe and demonstrate the ways you can use Seccomp, AppArmor, SELinux and cgroups to make your application containers as secure as possible - so you can build organizational and customer trust.

If you are new to my blog then you might be new to the concept of Linux kernel namespaces. I suggest first reading Getting Towards Real Sandbox Containers and Setting the Record Straight: containers vs. Zones vs. Jails vs. VMs.
Linux namespaces are one of the primitives that make up what is known as a “container.” They control what a process can see. Cgroups, the other main ingredient of “containers”, control what a process can use.

I’m tired of having the same conversation over and over again with people so I figured I would put it into a blog post.
Many people ask me if I have tried or what I think of Solaris Zones / BSD Jails. The answer is simply: I have tried them and I definitely like them. The conversation then heads towards them telling me how Zones and Jails are far superior to containers and that I should basically just give up with Linux containers and use VMs.

Over the past couple of years I have set out to create the ultimate Linux on the desktop experience for myself. Obviously everyone who runs Linux has their own opinions on things. What this post will outline is my ultimate Linux on the desktop experience. So just remember that before you get your panties in a knot on HackerNews because you live and die by Xmonad (I live and die by i3, fight me).

It all started innocently enough. I had “jfrazelle” as my GitHub handle for years, but my Twitter, IRC and other handles are all “jessfraz”. No one on GitHub was actually using “jessfraz” so I sat on it waiting to make my move.
I’m currently on vacation this week so of course I was looking to break all the things. One thing you must know about me is that at no point was I thinking I hate this.

Last week, I gave a talk at Github Universe and afterwards several people suggested I write a blog post on it. Here it is. This post will cover intricacies of “choosing your battle” and how personal passion for a project might conflict with corporate motives.
I have experienced open source from the side of the contributor, the side of the maintainer, and the side of the corporate-backed maintainer and contributor.

I was inspired last night by Cate Huston’s post, The Day I Leave the Tech Industry. I decided to write my own, except I’m not as eloquent a writer as Cate so before I go any further please, please, please read her post and not mine.
Mine is going to be a bit different. Lately I’ve been thinking more and more about this. It seems imminent. I’m only 27 and let me repeat: it seems imminent.

I really enjoyed Felipe Hoffa’s post on Analyzing GitHub issues and comments with BigQuery .
Which got me wondering about my favorite subject ever, The Art of Closing. I wonder what the stats are for the top 15 projects on GitHub in terms of pull requests opened vs. pull requests closed. This post will use the GitHub Archive dataset.
Top 15 repositories with the most pull requests First let’s find the top 15 repos with the most pull requests from 2015.

This blog post is going to be a bit different. After watching Stranger Things, my friend and I started discussing scary movies from our childhood. I couldn’t help but remember a very specific strange thing that happened to me growing up. I thought, hey, this would be a kinda weird blog post. So here it is. The events following are factual.
It was a hot, dry summer in July of 1995 in Phoenix, Arizona.

Hello and welcome to what will become the most sarcastic post on my blog. This is going to be a series of “buzzfeed” style programming articles and after this post I very happily pass the baton to Filippo Valsorda to continue. And I urge you to write your own as well.

Being an open source software maintainer is hard. The following post is geared towards maintainers and not contributors. If you are a new contributor to open source I would stop reading now because I don’t want you to get the wrong idea or discourage you. Tons of patch requests get merged per day, but this is going to focus on the ones that don’t.
I’ve talked to maintainers from several different open source projects, mesos, kubernetes, chromium, and they all agree one of the hardest parts of being a maintainer is saying “No” to patches you don’t want.

Containers are all the rage right now.
At the very core of containers are the same Linux primitives that are also used to create application sandboxes. The most common sandbox you may be familiar with is the Chrome sandbox. You can read in detail about the Chrome sandbox here: chromium.googlesource.com/chromium/src/+/master/docs/linux_sandboxing.md. The relevant aspect for this article is the fact it uses user namespaces and seccomp. Other deprecated features include AppArmor and SELinux.

Sup, let me give you fair warning here. Everything contained in this post is my opinion so don’t go getting your panties all in a knot on Hacker News because you don’t agree with me. I could honestly care less, because that’s the thing about my opinion, it’s mine.
I am going to give you my honest and dare I say it “blunt” opinion about each of the Docker graphdrivers so you can decide for yourself which one is the best one for you.

This is so cool I can hardly stand it.
In Docker 1.10, the awesome libnetwork team added the ability to specify a specific IP for a container. If you want to see the pull request it’s here: docker/docker#19001.
I have a IP Block on OVH for my server with 16 extra public IPs. I totally use these for good and not for evil.
But to use these previously with Docker containers meant hackery with the awesome pipework.

Almost exactly a year ago, I wrote a post about running Docker Containers on the Desktop. Well it is a new year, and I have ended up converting all my docker containers to runc configs, so it’s the perfect time for a new blog post.
For those of you unfamiliar with the Open Container Initiative you should check out opencontainers.org.
Why the switch? you ask… well let me explain.

Okay so this is part 2.5 in my series of posts combining my two favorite things, Docker & Tor. If you are just starting here, to catch you up, the first post was “How to Route all Traffic through a Tor Docker container”. The second was on “Running a Tor relay with Docker”. I thought it only made sense to show how to set up a Tor socks5 proxy in a container, for routing some traffic through Tor; in contrast to the first post, where I explained how to route all your traffic.

This post is part two of what will be a three part series. If you missed it part one was How to Route Traffic through a Tor Docker container. I figured it was important, if you are going to be a tor user, to document how you can help the Tor community by hosting a Tor relay. And guess what? You can use Docker to do this!
There are three types of relays you can host, a bridge relay, a middle relay, and an exit relay.

My least favorite topic in the world is ‘Women in Tech’, so I am going to make this short but I think it’s something that needs to be said.
This industry is fucked.
Ever since I started speaking at conferences and contributing to open source projects I have been endlessly harassed. I’ve gotten hundreds of private messages on IRC and emails about sex, rape, and death threats. People emailing me saying they jerked off to my conference talk video (you’re welcome btw) is mild in comparison to sending photoshopped pictures of me covered in blood.

So it turns out I’m pretty bad at vacation. I had this idea for a blog post and one thing lead to another and here we are…
You probably know by now I hate installing things on my host. At my previous job we did a lot of work with using Python and R for data science. I still love plotting data with ggplot and my favorite R package, wes anderson color palette.

This blog post is going to explain how to route traffic on your host through a Tor Docker container.
It’s actually a lot simplier than you would think. But it involves dealing with some unsavory things such as iptables.
Run the Image I have a fork of the tor source code and a branch with a Dockerfile. I have submitted upstream… we will see if they take it. The final result is the image jess/tor, but you can easily build locally from my repo jessfraz/tor.

This is a tale about how we use Docker to test Docker. Yes, I am familiar with the meme. Puhlease.
Many of you are familiar with the fact I work on the Docker core team. Which consists of fixing bugs, doing releases, reviewing PRs, hanging out on IRC, mailing lists etc etc etc. But what you may not know is that in addition to all these things I also manage our testing infrastructure.

If you are not familiar with Docker, it is the popular open source container engine.
Most people use Docker for containing applications to deploy into production or for building their applications in a contained environment. This is all fine & dandy, and saves developers & ops engineers huge headaches, but I like to use Docker in a not-so-typical way.
I use Docker to run all the desktop apps on my computers.

This blog post is going to go over how to create a Linux partition on your mac and have everything working successfully.
Okay so lets begin with:
sudo rm -rf / && sudo kill -9 1.
Hold the phone.
That was a test. I really hope you didn’t just copy, paste, and run a command on your host without knowing anything about the author. A bit about me… I have run this install about a dozen times on my mac, with various different changes along the way. I can finally say I found the perfect way to install Linux, specifically Debian Jessie, on a mac.
So now let’s actually get started.

I would just like to preface this by saying I do not condone cheating but I thought of this as a “challenge” and not so much as “cheating”.
A project I am working on required me to checkin to places on foursquare that I was not currently near (or even close to). Now the answer to this was pretty simple. Checkin through the API using the lat and long of the venue I was “supposedly” at. Boom. Worked without a flaw. Ok I will admit it I am kinda a competitive person and well, the foursquare badges are so pretty I immediately started thinking about how I could check in remotely and collect them all. But surely, surely foursquare must have some sort of catches in place that do not allow this. Because I was ever so curious to find out what they may be (…and how to get around them) I decided to try.

I saw this sign outside a coffee shop. Most people would just walk by and laugh, but it got me thinking. What would 2PAC do? Seeing as 2PAC is one of my favorite artists and I was already walking with earbuds on, I started playing an oldie but goodie on my iPhone, “Changes”.
