a positive but modest correlation between patience and risk tolerance. those more willing to wait for larger future rewards are also somewhat more willing to accept risk. r = 0.2 low time preference = more risk tolerance Related

Their words
Auto instrumentation has gotten so good in recent years. If you're using Open Telemetry and everyone should be using Open Telemetry. All of the common patterns like all of the models are trained on them. So, it is literally faster and easier to build with instrumentation than to than not to.

The simple answer is what the study showed was that 10,000 hours was the average amount of time that an expert violinist had spent practicing by the time they reached 20 years old. That's what the study showed. They weren't even experts by that point.

Just noticed a vibe-coded project of mine cost $200/month to serve a few dozen users/day 😭 Turns out it was doing 10s of millions of unnecessary Redis polls/day, even when idle - telemetry alone cost $$ a possible clue for why infra providers are growing so much right now Related

Telemetry is a product decision. These are not your old school infra logs and metrics; this is not your system exhaust pipe, spewing crap into the sky. The trace is all you need. But the trace must be part of the product. The trace is your source of truth. Quoting @mykola I think as LLM computer use gets increasing capable we are going to see a massive rise in the popularity and significance of telemetry. @mipsytipsy and honeycomb are way early yet, this will generalize. Think games or movies or lives as nested event streams. If you can see that, you can see why I’m… Related

This is what leads to slop JS/TS software. Treating errors generically like this is a mistake. It leads to fragile software, poor telemetry/observability/debugging, and as a result worse experiences

A korrent is a belief a person has stated in their own words: one
sentence stating the claim, backed by a quote and a source, kept at
korrents.com .
Under a name here, the quoted block is what they actually said.
The korrent beneath it is the claim those words support, in
korrents' wording — tap it to see the record, its source, and who
else holds it.
Nobody here wrote their own korrents. They are compiled from public
statements, and a person can change their mind, which is recorded too.

About the English under a post
Some people here publish in a language other than English. Where they
do, this site shows a machine translation beneath the post, in
this typeface — the site's own, not theirs.
The post itself is never changed, moved or hidden: what is set in the
serif above is exactly what the person published, and it is what to
quote them on. A translation can be wrong in ways that matter,
especially about tone.
Only the post's own words are translated. A quoted post, a linked
article and a belief on korrents.com
are left in their original language.
