> While listening to Chris, Dave, and Jen discuss the array of new things coming to CSS, what stuck out to me was how much these new things aren’t necessarily about addressing specific concerns around technological capability — e.g. when will we get IF statements in CSS? — but rather about addressing organizational and cultural concerns that arise from humans trying to work together to build software — e.g. how can teams of people write, maintain, and refactor CSS?
> I recently made my first R package and was asked how I did it. The answer of course was: I searched, read, and stumbled around until it was done. But having gone through the process I figured it was worthwhile summarising what I did and what I found tricky.
> RStudio Connect is a platform which is well known for providing the ability to deploy and share R applications such as Shiny apps and Plumber APIs as well as plots, models and R Markdown reports. However, despite the name, it is not just for R developers (hence their recent announcement). RStudio Connect also supports a growing number of Python applications, API services including Flask and FastAPI and interactive web based apps such as Bokeh and Streamlit.
> One of the reasons I prefer testing with Minitest is the dissatisfaction with my everyday RSpec work. Here are things I don’t like about typical RSpec test suites and how to fix them.
> Please take the post with a grain of salt. If you enjoy writing RSpec this way, keep enjoying it! Some things are personal, and it’s okay.
> The R Consortium recently interviewed John Blischak and Tim Hoolihan with the Cleveland R UseR Group. The organizers share more about how the group managed to continue to grow with consistent structured and casual virtual events like their Virtual R Café.
> Imagine if your smart speaker could be trained to recognize your accent, or if a pair of running shoes could alert you in real time if your gait changed, indicating fatigue. Or if, in the industrial world, sensors could parse vibration information from a machine that changed location and function often in real time, halting the machine if that information suggested there was a problem.
> GSoC 2022 is nearing its end so here is the final report on my project, which aims at adding more XFS file system support on Haiku.
> The Cox Proportional Hazards model has so dominated survival analysis over the past forty years that I imagine quite a few people who regularly analyze survival data might assume that the Cox model, along with the Kaplan-Meier estimator and a few standard parametric models, encompass just about everything there is to say about the subject. It would not be surprising if this were true because it is certainly the case that these tools have dominated the teaching of survival analysis. Very few introductory textbooks look beyond the Cox Model and the handful of parametric models built around Gompertz, Weibull and logistic functions. But why do Cox models work so well? What is the underlying theory? How do all the pieces of the standard survival tool kit fit together?
> The Address sanitizer is an awesome tool that does a lot more than just detect memory leaks. In this video I show you the basic usage of this tool using a leaky C++ code snippet
