Expanding on Tuesday's brief thoughts, here's a more complete write-up of why I think DNSSEC's costs outweigh the benefits: mattb.nz/w/2023/06/02/c…

I've had fun over the last month learning PCB assembly and design a bit better. mattb.nz/w/2023/06/27/d…

I enjoyed this conversation with Stephen and I hope you do too! On-call is not at all a topic that is likely to evoke strong opinions from folks, right...? If you want to chat more I'd love to hear from you!

Déjà vu all over again. My response to the UpStart Nation report released this week. I’m so tired. rowansimpson.substack.com/p/20230806

On-call in software teams has a bad reputation, but in the right environment it can be a powerful opportunity for growth. mattb.nz/w/2023/08/16/o… Do you agree? #sre #DevOps

So TweetDeck finally died unless I pay Elon money, which isn't going to happen. Twitter web UI is completely unusable and crap. So I'm likely not on here much anymore, unless there's another client option that still works?

Continuing from my last post, let's discuss the mental models I use to think about what on-call is and who is involved. This will give us some common ground for a practical discussion of how to realise the opportunity on-call presents: mattb.nz/w/2023/09/01/m…

The Slack redesign breaks the most useful feature. In the old design, I can see at a glance which Slack teams have unread messages for me. In the new design, I can see that there are unread messages but I have to click to examine which teams those messages are on. Do Not Want.👎

I'm trying out bluesky, if you're there and want to add me mattbnz.bsky.social

Sundar and Satya are two contrasting case studies in leadership. One rejuvenated a moribund company and positioned it as the leader in many emerging fields by making great strategic bets. The other can’t win at even core technologies the company pioneered in the first place.

Chris Evans incident.io I understand how frustrating this feels, and I have seen unethical behavior from Rootly in other contexts, so totally on your side here. But perhaps this was not the best example given that the most prominent UI element on both images is something that another site is known for.

A good example of how AI, when used as an assistant (not a replacement for humans), improves human decision-making.

The reason nobody found this problem in dnssec before now is that, as they say, the fundamental design flaws were completely hidden by the superficial design flaws. lwn.net/Articles/96292…

#F1Sprint what's up with all the missing timing graphics!?

11am: this will be a nice self-contained feature I can finish before lunch 6 hours later:

I'm pretty much 100% migrated to the new butterfly place for social media now. I still read here occasionally but I'd love to connect with you over there instead. My profile is under @[email protected].nz there. Find me and connect :)

✨ Big O ✨ Let me take you on a visual introduction to what big O notation is in my new blog post: samwho.dev/big-o. With big O notation you can better understand how algorithms will perform, finding orders of magnitude improvements with very simple changes to your code

One of the worst vulns I’ve ever seen. Makes you wonder who else knew about it and for how long. Kudos to Dirk-jan for uncovering it. dirkjanm.io/obtaining-glob…
