jwhitlark··on Texas’ power grid crumples under the cold
Wasn't the age, we just didn't want to pay for burying the power lines, so high winds in hot dry weather... Oops.
jwhitlark··on California ban on high-capacity magazines is overturned by federal appeals court

jwhitlark··on California ban on high-capacity magazines is overturned by federal appeals court
I think (perhaps) a better comparison is we don't allow people to shout fire in a crowded theater. Every right has some limitations, otherwise laws and government are irrelevant.
jwhitlark··on Roman Finger Counting
I one little sentence, you answered a lifelong question. Why 60?

Thank you!

jwhitlark··on Running decade-old games in containers
That sounds lovely! Was it playable? I'd love to take a look at the manifests, if you could make them available somewhere.
jwhitlark··on Ask HN: Feeling grossly incompetent working in opensource. What do I do?
Pain is weakness leaving the body, Feeling stupid is ignorance leaving the mind.

Embrace it. School is designed to give you set pieces that can be understood in isolation, the outside world rairly has that luxury. You won't truly improve without discomfort, though the particulars will be personal and multidimensional.

The end skill is solving problems in the wider world.

jwhitlark··on How did software get so reliable without proof?
In my experience, people either truely care about the business domain, and are willing to be uncomfortable to delve into it, or not. Types and proofs seem to be orthogonal.

Some domains are worth it, some are not. Sometimes it fits well, sometimes it doesn't.

Just don't be the one sinking into the muck saying, "...but the math worked". The math will be far more reliable than your understanding of the domain.

jwhitlark··on How did software get so reliable without proof?
Well, maybe. Additional costs with these approaches are often ignored. I wouldn't want to give up proof systems as a tool, but too many treat them as a zero cost panacea. A proof system or type checker is not an excuse to not give a fk about your craft, but I've seen it that way more frequently than I'd like to admit.

Personally and honestly, outside of already well understood or defined systems, I'd say that people should invest their time in understanding their business domain, before they dig deep into proofs and related techniques.

jwhitlark··on How These Things Work – A book about CS from first principles (2016)
I agree. I was deeply disappointed by "The Knowledge..."
jwhitlark··on Starlink Is a Big Deal
Depends on how they handle political issues. Cell networks are beholden to the local government, as they have to build infra there.

This might put more pressure on national firewalls.

jwhitlark··on SpaceX tests black satellite to reduce ‘megaconstellation’ threat to astronomy
This. Every change has some negative effect. The question is whether the net effect is positive or negative.
jwhitlark··on C Compiler from Scratch
Lisp in Small Pieces https://www.amazon.com/dp/0521545668/ref=cm_sw_r_other_apa_i... is excellent, and I think would help.
jwhitlark··on GitHub Actions is my new favorite free programming tool [video]
Level of previous knowledge assumed, tutorials tend to be more "starting from zero", and scope, guides tend to have a narrower focus.
jwhitlark··on Epsilon: The JDK’s Do-Nothing Garbage Collector
CDS and AppCDS, along with jlink, are also great for this.
jwhitlark··on Epsilon: The JDK’s Do-Nothing Garbage Collector
These days you can cut out most of that with jlink to trim down the jvm, and ClassDataSharing (CDS) and AppCDS. This post goes into it: https://blog.gilliard.lol/2017/10/04/AppCDS-and-Clojure.html
jwhitlark··on Kubernetes Config Connector: Provision GCP Infrastructure Using Kubernetes
I think these kind of tools are more about provisioning a "normal" cluster from an "admin" cluster. That way the power flows downhill, as it were.
jwhitlark··on Tract: A Hugo theme for ambitious documentation projects
I think more in the sense of "I believe this is better regardless of objective reality". The others convey that you like or are into something, this conveys that you won't be swayed, so anyone reading further had better be ok with that.
jwhitlark··on Really Small Java Apps
This seems to be about the sweet spot that I keep finding, although I normally work in clojure.
jwhitlark··on Google and Ambient Computing
I wonder if this feeling plays into the comfort of noun-verb over verb-noun that is being discussed at https://news.ycombinator.com/item?id=21271212
jwhitlark··on Whatever happened to Six Sigma?
I have heard that big consulting firms generally have a system per firm.
jwhitlark··on The Slackification of the American Home
Check out google data studio. Feels a better fit to me that tableau.
jwhitlark··on Writing a book, still the same pain 15 years later
I've always been curious how that scene works. It feels like a comfortable place for someone with broad curiosity and an ability to write. Do you have any insights?
jwhitlark··on Anthos – Build and manage modern hybrid applications
"If you have to ask the price, you can't afford it."
jwhitlark··on “Startup Robs Every Customer They Have for Thousands of Dollars Overnight”
No, it depends on the contract, and usually you forbid it, at least without approval, as things can get pretty nuts. There are some real horror stories.
jwhitlark··on K3s – Lightweight Kubernetes
Not necessarily. I've seen some k8s on IOT industrial use cases where it made sense. Solar power stations were one example, IIRC.
jwhitlark··on Build your own Mint
This problem is one reason why it's important to separate CI from CD. If you do that, then circleci would only have what's needed to test and package it, and the CD can handle the rest, although ideally you'll have a third piece for secrets.
jwhitlark··on How to Grow Old (1951)
Agreed.

Bertram Russell had an unhappy childhood and was divorced three times, (married four).

This thread seems to be stretched beyond the original premise.

jwhitlark··on Clojure REBL [video]
I was at the talk, and IIRC he said something about developing it while working with a client. It's quite likely it's a contract obligation.
jwhitlark··on Backdoor in event-stream library dependency
It always takes time for parasites to evolve in a new system.
jwhitlark··on Backdoor in event-stream library dependency
Yeah, no kidding.

That's why the idea of commercial support exists. You need to depend on it? Pay for it.
