InfoWorld articles
Today I discovered InfoWorld with these articles:
- Complexity is killing software developers
- Why you should use a microservice architecture
- No one wants to manage Kubernetes anymore
And a bonus article from Spotify: How We Use Golden Paths to Solve Fragmentation in Our Software Ecosystem .
Also, I should note, I very much like the InfoWorld URL format: https://www.infoworld.com/article/3614850/no-one-wants-to-manage-kubernetes-anymore.html — this is the same URL structure I use in my own designs.
Unicode Utilities: Confusables
Today I was referred to: Unicode Utilities: Confusables.
Unicode bidirectional override hack
Interesting: Security advisory for rustc (CVE-2021-42574).
As an example, the following snippet (with {U+NNNN} replaced with the Unicode codepoint NNNN):
if access_level != "user{U+202E} {U+2066}// Check if admin{U+2069} {U+2066}" {
...would be rendered by bidirectional-aware tools as:
if access_level != "user" { // Check if admin

Surrogate Key and Natural Key
In Database Design 25 – Surrogate Key and Natural Key the presenter Caleb Curry agrees with my view that if you expose your surrogate keys they become natural keys. See around t=5:00.
Time To First Byte
This was suggested on #lobsters today:
$ curl -o /dev/null -w "Connect: %{time_connect} TTFB: %{time_starttransfer} Total time: %{time_total} \n" https://www.progclub.org/
How To Design A Good API and Why it Matters
Today I watched: How To Design A Good API and Why it Matters. Good talk. Favourite quote:
Inheritance violates encapsulation
Oh, and I followed on with: A Brief, Opinionated History of the API wherein (t=28:14) Bloch says it’s an API if you can answer yes to both of these:
- Does it provide a set of operations defined by their inputs and outputs?
- Does it admit reimplementation without compromising its users?
