🖤 It's time to speak up, donate or even just stream a fundraising video, because Black Lives Matter. Our thoughts are with everyone in the US and beyond fighting for this cause.

StatusCode Weekly
Covering the week's news in software development, ops, platforms, and tooling.

The Stack Overflow Developer Survey 2020 Results — Over 65,000 developers took part in Stack Overflow’s popular annual survey and you can now swim through the results. We learn lots of things, including:

  • JavaScript is the most popular language amongst respondents.
  • MySQL holds the top spot in databases.
  • Python is the language people most want to learn.
  • 78% enjoy coding as a hobby, as well as work.
  • Perl is where the money is(?!)
  • Men are disproportionately represented in all fields of development, but particularly in devops and sysadmin, and much less so in data science and education.

Stack Overflow

Remote Instructor-Lead Go, Docker, Kubernetes & Python Training — We offer live-streaming remote training sessions for individual engineers and companies that want to augment their knowledge in Go, Docker, Kubernetes & Python. We’ve trained over 5,000 engineers via our carefully crafted classes.

Why Is Kubernetes Getting So Popular? — At about six years old, the pace of Kubernetes adoption only seems to be surging. Stack Overflow’s Ricardo Aravena explores why it’s so appealing. Hacker News had some good discussion on the topic too.

Stack Overflow

SQLite 3.32.0 Released — The world’s most popular database takes another baby step forward:

  • Support for faster ‘approximate’ ANALYZE queries.
  • A iif() SQL function which acts like an “IF” in other languages, or like CASE WHEN X THEN Y ELSE Z END in more traditional SQL.
  • You can now include up to 32766 parameters in a query, up from the previous maximum of 999. (I’d like to see code doing that!)


Cloudflare Speed Test: Measure The Speed and Consistency of Your Connection — Netflix has Fast.com and there’s good old Speedtest but now Cloudflare has their own take on the Internet connectivity speed test. It takes an interesting approach by focusing on 90th percentile speed and shows jitter too.

Using Amazon Kendra to Help Answer 10th Standard Science Questions for My DaughterKendra is a new AWS service for querying data using natural language and it’s very much “enterprise” given how much it costs.. Nonetheless, if you want to use it to help with your kid’s homework, it’s totally possible.

Snowpack 2.0: A Build System for the Modern Web — Say bye-bye to your bundler and let modern browsers’ ES module support do the heavy lifting with Snowpack.
