Hi everyone! πŸ‘‹

Welcome to cron.weekly issue #148.

Looks like everyone’s been hiding their acquisition news until September, with major news from both Chef and Caddy this week!

Hope you’re all enjoying your weekend. Now it’s time for β˜•οΈ.

News & general πŸ—ž

Linux 5.0 To Linux 5.9 Kernel Benchmarking

This post contains very in-depth benchmarking of all kernel version between 5.0 and the latest 5.9. It surprised me how different the results can be for some services, depending on the application workload you may benefit from a different kernel version!

Debian project has plenty of money but not enough developers

An interesting read about the ethos of the Debian project. A conservative approach to its financials has resulted in a nice war chest, but no developers.

Caddy Server is acquired

Free open-source product Caddy has been acquired by Apilayer. Caddy and CertMagic have new ownership, but there are no changes to licensing or development. In fact, it allows Matt to work on Caddy full-time now.

Progress to Purchase Chef

Progress, the company, has purchased Chef, the popular config management system.

Certificate lifetime limited to 1y since September 1st, 2020

I forgot to mention this in last week’s issue, but since September 1st 2020, new (trusted) certificates have a maximum lifetime of 398 days (roughly 1 year). Some more details are available on the Oh Dear blog.

Why I Actively Discourage Online Tooling

I agree with this post: many developers & sysadmins use online JSON validators, formatters, linters etc. but are often unaware what sensitive data they’re putting on unknown websites. It’s the main reason I built my own JSON formatter, simple random data generator, and sha/md5/base64/URI encoder.

Introducing GitHub Container Registry

With Docker Hub announcing rate limits on its container repositories, it seems like a smart move from Github to announce their plan to offer container registry.
