The FHIR standard started as a better way to exchange healthcare data, but it also provides a solid basis for deep analytics and Machine Learning at scale. This post looks at an example from the recent FHIR DevDays conference that does just that. You can also run the interactive FHIR data engineering tutorial used in the conference yourself. Our first step is to bring FHIR data into a data lake – a computational environment where our analys..

Time is precious - once again, I only managed to fit in one book in my busy schedule for the month. Hopefully, come August, I’ll have more time, since the last session for the last class in my Master’s program is on July 25th. Of course, my son might be mobile by then - he’ll be four months on the 26th - so he will require more attention.

Lately I’ve been thinking about how easy it is to fall into the trap of not challenging our ideas about the code we’re working on. In order to challenge the default mindset of Clean Code, I recently proposed to institute Dirty Code Monday (a proposal that sort of got me into a bit of a big discussion). Anyway, here is the report from the first successful Dirty Code Monday one week ago:

Over the years I’ve learned about many of the advantages of using a modern terminal and shell. I’m talking about using bash with GNOME terminal on a modern GNU/Linux distribution. I particularly like switching between the terminal and GUI applications. It’s now even better. Automatic Hyperlinks : Occasionally, some program running in your shell might output what looked like a link: gnome terminal and vte will automati..

I’ve been wanting to scratch a writing itch for quite a while. Over the last twelve months I’ve had the good fortune of having visited nine countries. And every one of those trips involving some amazing stories with great people. In April, I broke my collarbone while mountain biking in Peru (I’ll do a writeup on that at another time), which provided no small amount of downtime to think about what to do with my time when I’m not out being ac....

Debugging a complex problem is tough, and it can be especially difficult when it's not obvious which chunk of code is responsible. It's common to attempt to produce a reduced test case in order to narrow it down. It's tedious to do this manually, but it's also the sort of thing computers are really good at. C-Reduce is a program which automatically takes programs and pares them down to produce a reduced test case. Let's take a look at how t..

With the external release of OCaml 4.07.0 imminent, we in Jane Street’s Tools & Compilers group have been planning what we want to work on for inclusion in OCaml 4.08. These days OCaml uses (or at least attempts) a time-based release process with releases scheduled every 6 months. We’re trying to avoid rushing in changes at the last minute – as we’ve been prone to do in the past – so this list is restricted to things we could conceivably fi..

Zip Slip is a form of a Directory Traversal that can be exploited by extracting files from an archive. This cheat sheet informs you of vulnerable libraries and code snippets that are exploitable to a Zip Slip attack. Additionally it provides you with the information you need to upgrade to fixed library versions and offers tips on how to find and fix your own vulnerable code.

Containers are becoming the standard form in which applications are packaged and executed, so the need to protect not only the application itself but the entire container against open source vulnerabilities is growing.

I recently did a few days of TDD training for a client. They asked me to help them test and refactor a class that created XML from an internal domain model. This gave me the opportunity to examine a bigger pattern. I wondered where the domain model came from. Looking through the code base, I found that the same or similar data structures were dealt with many places. As often is the case, I also found a bit of code that parsed an XML structu..

At the end of last month - the last day, in fact - I signed up for a Robinhood account. I signed up mostly for fun - but also for the free stock that Robinhood is currently offering. I got Chesapeake Energy (CHK), which is worth only about five bucks. However, some people get stocks worth a couple hundred dollars, such as Facebook or Apple.

PostgresOpen is just a few months away and our list of talks is now live and available on the PostgresOpen website. This year selecting the talks was the hardest yet not only due to the number of talk submissions, but also the across the board high quality of submissions. There is hopefully something for everyone among the talks, at least if you like Postgres that is. If you’re thinking about joining us I’d love to see you there and bu....

In this post we’ll look at the most common types of vulnerabilities for two of the main ecosystems we track in our vulnerability database, namely Maven Central and npm. The Snyk Vulnerability database consists of vulnerabilities from over 1,000,000 open source packages we track that use Composer, Go, Maven Central, npm, NuGet, pip and Rubygems.

Introduction I teach a class called Ultimate Go . The class is three days long and teaches you the history, mechanics and semantics of the Go programming language. The idea is to teach you how to read code to the level that you can understand the behavior and impact your program is having on the machine. This helps you make better and more consistent engineering decisions. At the same time, the class is very focused on teaching you how ..

My previous blog post took off on Twitter. It pointed out a problem: Insisting on the obligation to follow certain rules at all times isn’t actually helping people work better. The most common question (or objection) I got to the blog post was: So how do we teach new coders how to code well. This blog post is about that topic. First learn to collaborate The most important skill we should teach is how to work well with others on a shared cod..
