Growth in code bases come with exciting scalability challenges. As the size of our iOS codebase and team at SoundCloud grew, we faced challenges: long compile times and conflicts. Our productivity started to suffer as a result. We took inspiration from the work done in the backend (Building Products at SoundCloud) and applied it to mobile development. The main goal was to get back to a state where development is fun, fast, and would scale a..

Earlier this week we started the process to upgrade one of our hypervisor compute clusters when we encountered a rather painful bug with HP’s Broadcom NIC chipsets. We were part way through a routine rolling pool upgrade of our hypervisor (XenServer) cluster when we observed unexpected and intermittent loss of connectivity between several VMs, then entire XenServer hosts. The problems appeared to impact hosts that hadn’t yet upgraded to..

From boiling lead and black art: An essay on the history of mathematical typography

Math fonts from six different type systems, courtesy Chalkdust I’ve always felt like constructing printed math was much more of an art form than regular typesetting. Someone typesetting mathematics is less a “typist” and more an artist attempting to render abstract data on a two-dimensional surface. Mathematical symbols are themselves a language, but they are fundamentally a visual representation of human-conceived knowledge—knowledg....

Dear Postgres, I’ve always felt an affinity for you in my 9 years of working with you. I know others have known you longer, but that doesn’t mean they love you more. Years ago when others complained about your rigidness or that you weren’t as accommodating as others I found solace in your steadfast values: Don’t lose data Adhere to standards Move forward with a balancing act between new fads of the day while still continuously improving....

1600 words, 8 minutes. You’ve suffered a breach. Your security was circumvented. Data was lost and the public, shareholders, media, and perhaps regulator must soon be informed. A chain of events has begun. What you do next will determine in large part where that chain leads. In this post I’m going to talk about a tactic I’ve seen used to successfully re-frame a bad situation and nudge the narrative in your favour.

Michael Feathers says that legacy code is any code without tests but I’d go a step further and say that legacy code is any code that is still running even though the original developer(s) are no longer working on it. And there is certainly plenty of that in financial institutions. There are other characteristics too, such as: unreproducible production environment incomplete source control missing files ‘master’ fails to build no a..

Python 3 and Python 2 have various functional differences. On their own, they’re not necessarily better or worse (though arguably Python 3 should be an improvement), but any change may introduce risk. This post highlights and explains a few differences between the versions that have security implications.

In 2010, a group of designers from Columbus, Ohio set out to create a grassroots, cross-discipline, and creative conference. Since that first event, Midwest UX has been an ongoing tradition that attracts innovative ideas and provides an opportunity for regional professions to engage in discussion with other professionals. Last year, Amber Wilks and Dr. Becca Green were invited to take their talk from DevCon 2016 on the road to Midwest UX.

In early 2015, I was working at an artificial intelligence startup. My team was planning to build a web application to connect to our neural network platform. The team as a whole had experience (on the AI–side) with Python, and the web team had a lot of experience using Django. We’d implemented a hybrid-app in Cordova using Backbone.js the previous year. My task was to evaluate the state-of-the-art in the frontend development landscape. I....

One year ago I’ve started to collect temperature from my house using Acurite sensors. These sensors are not too expensive and good quality but the “base” aka the radio receiver connected to internet is costly and totally closed, it’s sending your data to the Cloud™, it’s not just Acurite, all those “IOT” devices are generally poor on the software side. Receiving radio data Most of these sensors have their protocols already reverse engineere..

PacBSD is a FreeBSD kernel/world with a PacMan Arch package manager and an optionnal OpenRC init system. In short ZFS, DTrace and the FreeBSD kernel but the simplicity of Arch for packages management but the Gentoo init. It’s experimental, uncompleted, unfinished, lacks proper documentations but it works and could be/should be the solution we are waiting for :). Here is some notes on installation (in QEMU), note that it slightly diverges fr..

Flat UI DynamoDB Tables WTF is with dynamodb not having the concept of a database. This is terrible. Now we need to configure every table name for each deployment? Terraform Drop Heads up, if you use terraform and change your dynamodb table key schema, it will drop and recreate you....
