Docker layer caching is complicated! CircleCI has an implementation that used to use a detachable disk, but that had issues with concurrency It’s since been replaced with an approach that uses a docker plugin under the hood to store layers

I have to disagree with this. Yes existing terms have meaning, but they also have baggage. Forming a new term is a reasonably effective way to shed that baggage and attempt to start the cycle all over again. Seeing a term you’re not as fami

A sales team gets measured on the sales they make - but they don't own the end to end process of building the thing that they're selling. It's entirely possible to measure teams on business outcomes without having them own th

Are you suggesting that the macroeconomic environment in terms of funding and performance expectations of startups hasn't changed signficantly in the last few years? VC-money and ZIRP is a convenient shorthand for what's changed,

In my opinion the best antidote to overly complex architectures is to have engineering teams and the engineers in them be rewarded based on actual business outcomes. I suspect the era of VC-money and ZIRP led to a large number of engineers

Am I missing something? Couldn’t they allow you open PWAs in Safari, or fall back to opening a URL in another browser? Is there some part of the DMA which demands full feature parity?

it's also worth noting that even on the same platform, compiling with CGO enabled creates a dynamic link against `glibc`, which creates a dependency on having the matching version in your deployment target. We ran into this recently as

The purpose of pair programming and the purpose of code review are not quite the same. Pair programming is a high-context activity where two programmers collaborate closely on building something. Code review is a tool to simulate looking at

If you're only monitoring user-facing symptoms, and the application restarts quickly enough to not cause a blip in service, then: a) It's highly likely that your monitoring is not going to spot an occasionally restarting service b

This is a great cautionary tale about what happens if you don’t continuously integrate changes in an incremental fashion.

I used to work at CircleCI. It was often suggested to us that because of the usage-based pricing we were not incentivized to make builds faster. In reality the opposite was true - experience had shown us that every time builds got faster, p

The government can also buy things (like infrastructure) and employ people to provide public services, which directly injects money into the economy by paying it to the people who do that work. The current UK government has not been doing m

Something I think hasn’t been discussed much in these comments is what the alternative would look like, and why that is undesirable. If you only perform the refactoring after making a change (eg. adding a ticket for cleanup later), then (

For web-style application code my experience writing Go code says that you totally can stop using logs and just use traces and have just as much visibility into a running process, if not more. For library code or other deployment models I’m

A counter or a timer is clearly no substitute for a log, that would be an absurd statement for me to have made - which is why I said no such thing. A span as modelled by OpenTelemetry is a a bag of developer-chosen structured data containin
