bradreaves2··on Remembering GitHub's Office, a Monument to Tech Culture
Only for an hour.
bradreaves2··on A Gambler Who Beat Roulette
Claude Shannon[1] claims he did something similar in the early 60's, proving it worked in Vegas. He and his collaborator Ed Thorpe quit playing well before the legitimate businessmen who ran the casinos could realize they were winning too much and have a friendly chat with them about it.

[1] If the name doesn't ring a bell, he discovered that Boolean logic could be used to analyze and design electric switching circuits -- as a Master's thesis. He went on to a storied career at Bell Labs where he invented Information Theory.

bradreaves2··on What happens when you leak AWS credentials and how AWS minimizes the damage
Really interesting experiment!

To answer "how do the bad guys find them so quickly" the answer is "judicious queries to the GitHub API."

My research group describes how this works, and what we could see with it, in this paper: https://bradreaves.net/mmr19.pdf

We're currently working on follow up work to make secret management better (with NSF funding[1]), and we're always looking for research collaborators[2].

bradreaves2··on Twitter will open source all code used to recommend tweets on March 31
Do they know that March 31 is actually a real day?
bradreaves2··on 4-day workweek trial
I worry about publication bias with these studies.

If a researcher finds the counter-intuitive results that working less leads to equivalent or better outcomes, it will be a headline.

If a researcher finds that working less leads to getting less work done, who would publish it? It won't get media headlines, but even scientific journals will not accept the results.

bradreaves2··on Ask HN: Concise, pragmatic baby manual for first-time dad?
Sounds like you want the Army Ranger’s Field Guide to Infant Civilians, which sadly doesn’t exist. The kind of people who write books about parenting can’t help but put in anecdotes and cute stories.

That said, the most helpful resources for me have been:

1. Happiest Baby on the Block. Chapter 1 is an outline of the full book and is pretty close to what you ask for. I had never cared for a child before, and reading it before my daughter was born made me “baby whisperer” for the first week.

2. Everything from Emily Oster.

3. A standard text on pregnancy. “What to expect…” and “Bumpin” are actually not bad from your perspective. They tend to do a good job of outlining the essentials and spectra of choices without being too opinionated.

And finally: get set up with a good peds office before baby is born. Look for 7 day/week office hours and a 24 hour call line. We needed to contact ours the night we came home — don’t put this off till the kid is born!

bradreaves2··on Ask HN: What are the foundational texts for learning about AI/ML/NN?
This is off the beaten path, but consider Abu-Mostafa et al.'s "Learning from Data". https://www.amazon.com/Learning-Data-Yaser-S-Abu-Mostafa/dp/...

I adore PRML, but the scope and depth is overwhelming. LfD encapsulates a number of really core principles in a simple text. The companion course is outstanding and available on EdX.

The tradeoff is that LfD doesn't cover a lot of breath in terms of looking at specific algorithms, but your other texts will do a better job there.

My second recommendation is to read the documentation for Scikit.Learn. It's amazingly instructive and a practical guide to doing ML in practice.

bradreaves2··on Pornhub users in Louisiana now have to submit government ID to access the site
There is a big difference between flashing a card at point-of-sale and having to register for a permanent record with the state.

When the database leaks — and it will - we know what it will look like: the AshleyMadison leaks. People died.

There are plenty of technical mechanisms that are available to parents and schools (etc) to block access to this material. None of them need involve the state.

In the end, we must treat this like any other substance that children aren’t ready for. Whether we are talking about taking cannabis, alcohol, pornography, or Tide pods, the most effective protection is parents and educators who care and teach children about potentially harmful behaviors.

bradreaves2··on The cost of cheap TVs
I have been reading tech folks lament the disappearance of dumb screens for years.

I finally bought my first new TV in 2020, a Sony with Android TV. I have never connected it to the Internet. Instead, it displays an AppleTV or a gaming machine.

It has been an amazing reliable display at a reasonable price, every bit as good as the imagined ideal dumb TV.

So why all the pearl clutching? Do other brands require Internet to turn on and display HDMI?

bradreaves2··on Kanye West to acquire free speech platform Parler
"Privately-owned platforms [that] do as they please" but call themselves “free speech” are dishonest.

This isn’t partisan hypocrisy — it’s applying an objective standard to a bad-faith argument.
