Synthesized notes from my own experience capitalizing software costs and the thoughts from this thread into lethain.com/capitalize-eng Def curious if I missed anythign!

What process does your engineering team use for the capitalization vs expensing process with finance? I've seen everything from "tickets for every work item" to "team affinity to innovation/maintenance" to "ignore it until we go public" and all seem bad. What is better way?!

I hate meetings as much as anyone. I tend to think meetings are more misunderstood than abused—a misunderstanding of what they are good for and general expectations. For me the key element of meetings is that they are where and how culture is built and reinforced. 1/3

I think the biggest blocker for going down this path is people start thinking about measuring outputs without understanding the inputs first. If you start with measuring outputs, the whole process is going to feel like magic and that makes the entire thing feel unobtainable.

This is a fantastic article. I cannot recommend the "Using optimization metrics to judge performance" antipattern enough. It's your job as an engineering leader to avoid going that route. It's different to operate a MariaDB cluster than an API that receives 5 rqps.

"What should I measure when the CEO asks for engineering metrics?" is probably the most frequently recurring eng leadership question, and connects into a larger, somewhat nebulous topic: how should you measure engineering organizations? Some notes! lethain.com/measuring-engi

Finally, I also find many companies have cargo-culted measurement ("Amazon measures, so we should too"), but measurement is only valuable if you actually inspect the data is accurate, generally by building and endlessly refining an accurate mental model about what the data means

The biggest challenge with answering this question directly imo is that there are a number of different stakeholders who all want very different things, and literal attempts to answer usually get artificially anchored on one of those stakeholders rather than solving for whole set

It's here!! My new zine "The Pocket Guide to Debugging" is out now!! It has 47 pages of my favourite strategies for solving your sneakiest bugs. 🔎🐛 Get it here for $12: wizardzines.com/zines/debuggin

a very cool person wearing bug jewellery and a backpack is inspecting a bug with their magnifying glass. They have curly brown hair and light brown skin. 

their laptop (with bug stickers) and a bug catching net are nearby

Ok, so expensing versus capitalization of eng efforts within GAAP accounting. I find that many finance teams are willing to accept expensing full eng costs, but other finance teams view that as impossible -- why so much inconsistency across finance teams? What's "correct" in '22?

Did Amazon subtly change its URL format for items? Running into a surprising number of recent breakages when googling for books, clicking on first item, then getting 404s. (At first thought I'd cookie'd into a non-US Amazon subsite or something, but see no evidence of that.)
My biggest question to myself is whether I should try harder to read more memorable books 😅 (I'm leaning towards "no", there are lots of reasons to read books, only one of which is that they might be memorable)

Another great year for reading and learning. Back when I was a manager I bought books each yr for team’s senior managers to inspire/expand. Here’s a list of books I might have purchased for holiday 2023. I might not agree but definitely learned and made me think. Happy 🕎 🎄❄️ 1/

Interesting! (I’ve never found Twitter searches to find my own tweets , which I’ve always wondered about — which is why I put all my tweets into a Slack channel, and others in a database, so I can find tweets more reliably. The blog post makes me think this has been fixed)

Twitter’s search indexes are definitely lagging, although in the sort of ambiguous, partial failure sort of way that you’d expect from a distributed system. (Or caching of search results isn’t getting expired consistently, etc.) Curious to see if this gets fixed!

Good question, Will! On audiobooks where I'm paid upfront (/no royalties), there's almost certainly review benefits like boosting my overall narrator profile (and making ACX/Audible take me more seriously). It's all intangible, but I believe your instincts in this are sound.
