Feds must answer email on what they did last week — or lose jobs, Musk says

One of my favourite lil’ side projects was a synthesizer I built almost a decade ago.

I’m digging into the code, and it’s actually not terrible? I’m surprised. 😂

Figure out what to cache server-side - make your users happy with a faster site & boss happy with lower infra costs

new post on finding caching opportunities! I go through some common patterns you can see in a Sentry waterfall, in particular - sequential / repeated queries, overused queries, etc. Take a read! blog.sentry.io/using-server...

the sentry devrel team (@whitep4nth3r.com , @guthals.com , @nikolovlazar.com) does an absolutely kick-ass job at creating our devrel experience, far beyond just cranking out (insanely good) content.
if you're also in this world, this is worth a read!!
I've been working with @guthals.com to define a content framework that is optimised for DevRel success at @sentry.io, which started with an exercise to categorise existing content.

Bonus: I've created a spreadsheet template you can use to do the classification exercise with your own content.
Stop writing SEO-first! These are the 4 types of DevRel content (plus their Leading Themes)
Discover how to classify DevRel content to understand what works for your team. Learn about 4 content types, their goals, and leading themes.

Optimizing type perf is like an even less intuitive version of optimizing code for V8.

Some stuff that looks super expensive is actually irrelevant; some stuff that looks innocuous is actually a massive problem.

All you can do is learn heuristics, iterate and pray 🙏

Earnest post, but: a thing I like here is it’s okay to have moments of happiness in public without being broadly scolded, and I believe that sustaining this kind of humanity will be very important as we resist fascism.

We have to sustain each other. Making joy isn’t denial, it’s how we will survive
