You never really appreciate disk space until it’s all gone. This morning I
noticed that my laptop had come perilously close to exhausting all its
available disk space. Oops! Normally I would prune some Docker images with
docker system prune -f
but this time around I couldn’t blame Docker, the
wasted space was due to cargo,
critical part of the Rust development toolchain.
Howdy!
Welcome to my blog where I write about software
development
, cycling, and other random nonsense. This is not
the only place I write, you can find more words I typed on the Buoyant Data blog, Scribd tech blog, and GitHub.
Using serde's deserialize_with to handle custom strings
I stumbled across a crate which implemented string parsing that I
wished to incorporate into some of my serde.rs
deserialization code. Unfortunately the crate in question,
cron does not implement the
#[derive(Deserialize)]
macro on its Schedule
, so I needed to fiddle with
one of serde’s “field attributes” in order to move forward: deserialize_with
.
Building a real-time data platform with Apache Spark and Delta Lake
The Real-time Data Platform is one of the fun things we have been building at Scribd since I joined in 2019. Last month I was fortunate enough to share some of our approach in a presentation at Spark and AI Summit titled: “The revolution will be streamed.” At a high level, what I had branded the “Real-time Data Platform” is really: Apache Kafka, Apache Airflow, Structured streaming with Apache Spark, and a smattering of microservices to help shuffle data around. All sitting on top of Delta Lake which acts as an incredibly versatile and useful storage layer for the platform.
Building an Azure Function to send IRC notifications with Rust
Delivering a simple payload to IRC is an ideal use-case for Function-based cloud computing. Last year when GitHub discontinued their service for pushing notifications into IRC channels, I had a perfect situation to couch-hack with a library I had recently discovered: Azure Functions for Rust
Building and debugging a high-throughput daemon in Rust
The async
/await
keywords in modern Rust make building high-throughput
daemons pretty straightforward, but as I learned that doesn’t necessarily mean
“easy.” Last month on the Scribd tech blog wrote
about a daemon named hotdog which we
deployed into production: Ingesting production logs with
Rust. In
this post, I would like to write about some of the technical challenges I
encountered getting the performance tuned for this
async-std based Rust application.
Reading RSS feeds from wacky protocols with newsboat
Much of the information I read during the day, not counting e-mail, comes from my RSS reader: Newsboat. Whenever I see an interesting blog post on Twitter or elsewhere, I habitually subscribe the author’s RSS feed. I recently stumbled across an interesting RSS feed which wasn’t served over HTTP, leading me to wonder: how can I subscribe?
A terminal in your editor in your terminal
I discovered today that since version 8.1, Vim apparently supports spawning a terminal from within the Vim editor. This is a handy little feature that could make life easier for checking documentation, running tests, and so on.
Writing Rust unit tests with async-std
I have been writing a lot of Rust lately
and as a consequence I have had to get a lot better at writing unit tests. As
if testing along weren’t tricky enough, almost everything I am writing takes
advantage of async
/await
and is running on top of the
async-std runtime.
Hosting Remote Eng Management Office Hours
Suddengly managing a remote engineering team may seem like a daunting situation, one which many people are suddently finding themselves in as tech companies institute sudden “work-from-home” policies in response to the Corona virus. If you find yourself in this situation don’t panic. Managing remotely is not significantly different than managing in-person, and your already existing good management and communication habits will greatly help. Nonetheless, I thought I might be able to help newly remote managers by hosting an open office hours, with the first experimental session yesterday in the afternoon PST.
Open Build Service is a sysadmin secret weapon
If you are a sysadmin, Open Build Service is one of the tools you should add to your toolbox..today. “OBS”, hosted at build.opensuse.org is one of my favorite “killer apps” for openSUSE, yet for system administrators it has continued to be relatively unknown, but disproportionately valuable. At a high-level OBS is a tool for building and distributing packages, but on build.opensuse.org, there’s a social component which may someday save your bacon!
