I only hold a strong opinion about "set to". There are two cases to distinguish:
- Assignment (i.e. first setting a variable)
- Mutation (i.e. change a variable later on).
For Assignment a lot of options are fine. I like `:=`.
Mutation is a whole different animal, which bring…

Look, I've been in the "controversial interview" seat. What @donlemon came after @elonmusk with felt like malice. Elon—in clear discomfort—opens up in good faith about intensely private struggles; Lemon picks precisely that moment to begin emptying an entire drawer of knives. 1/
Just used this little combo to run a live-reloading HTTP dev server, without installing anything:
, npx live-server
This makes use of github.com/nix-community/…. I don't even have npx installed.
With #nix "installing software" is largely reduce to caching static files - which…
Distributing applications with nix is quite magical ... when it works. The following one-liner should bring up a little game I created with C+Raylib yesterday:
nix run github:HeinrichHartmann/ray-mult
I developed this on OSX, and it *just-worked* on my Linux Desktop 🎉…
We've just released rds-health, a CLI utility that incorporates insights from past incidents, anomalies and empirical observations into a methodology of observing the health status of AWS RDS using 12 golden signals: zln.do/49J54jw#OpenSource#SRE#AWS#PostgreSQL
Big news! Circonus has been acquired by Apica.
This acquisition is a major step in redefining data management & observability for enterprises. Get ready for unmatched innovation in observability data management: apica.io/news/apica-acq…#Observability
@ChiefScientist I’m not interested. It’ll only hurt someone’s feelings or cause drama, and a lot of the people on both sides are personal friends. I haven’t worked on TF for 4 or 5 years, haven’t been in leadership for 2 years, and now I’ve left. There’s no upside. Maybe in like 10 years.
Can we talk about how NVIDIA is about to be worth more than Google (Alphabet).
One is in hardware where margins were traditionally low; the other is in software/ads, where margins traditionally high.
The execution at NVIDIA is something else.
My wife is a trained accountant, and does exactly this for all our assets. Real game-changer for getting on-top of finances.
As a math/IT guy, I was trying to integrate APIs/CSV and get on-top of all the transactions -- a futile task. Just grab the totals every month!

# Ostensive Severities
Instead of using vague description or impact thresholds to define severity levels of operational incidents, we are trying a new approach where we include a list of concrete example incidents to anchor severity levels in the context of our company.
