💌 A valuable message from Russ Cox

Over on the golang-dev mailing list, Russ Cox posted a valuable message:

Go development is not isolated from world events; work on Go always comes second to more basic concerns like personal and family health and safety. Nearly all of us are working at reduced capacity these days. I expect that capacity to drop further over the next few months.

[...]

If our own working capacity is reduced but we keep the same timelines, then we must reduce the scope of what we expect to be in the release. Some new features or planned won't make it. That's OK - we'll get them next time. We all need to accept that, for our own work and work by others.

Most of all, let's all please be extra kind and charitable with each other. It's always good advice to remember that you don't know what external stresses are affecting the person on the other end of the email, review thread, or GitHub comment, but it's especially important now.

The above is just a quick summary of the main points, but it's also worth reading in full. Thanks Russ.

Dear reader,

Long before we'd heard the term 'covid', we'd planned to take Easter Friday (today) off and tell you about this in last week's issue. But we forgot 🤭

As we tend to get lots of emails whenever we merely publish late, I didn't want to run the risk of everyone thinking we were in trouble by not sending anything :-)

So we're back next Friday but while I'm here, I have a few links to share:

Go 1.14.2 and Go 1.13.10 have been released but they're pretty minor releases, so no panic.
Last week we launched JAMstacked, a new bi-weekly newsletter focused on the growing trend of statically rendered by dynamically front-end enhanced sites and apps commonly referred to as 'JAMstack'.
If you're itching for something to do, Ilija Eftimov has put together a walkthrough of building a TCP-level protocol in Go.

As always, we hugely appreciate your support and that you continue to read the newsletter, check out our sponsors, and send us things to include each week. We are only a 'Reply' button away if you need us.

Happy Easter if you celebrate it. Happy Friday, if you don't 😄

— Peter Cooper and the Cooperpress team

P.S. If I were going to recommend just one of our other newsletters to check out, it'd be StatusCode Weekly. It's a general roundup of useful programming goodness, often with a lot of interesting stories thrown in.

This week we featured a VS Code extension that encourages you to take breaks, a compilation of explanations of Unix package names, some technical writing courses Google has shared, a clever Google Maps API optimization and, well, a lot more.
