shafoshaf··on Starlink signals can be reverse-engineered to work like GPS
Aren't the Russian drones using GPS? Why wouldn't Ukraine jam GPS?
shafoshaf··on Against Algebra
Just living life requires basic algebraic skills. Loans, insurance, taxes, and virtually any kind of projection into the future require concepts like X = 2Y. Understanding that something is linear or exponential is critical to and to understand when one is better than the other requires that someone learn how we as society express those concepts, which is algebra.

The person who can't read can be a traffic guard, server (with the right cash register), bricklayer, or any of a number of jobs. However, all of those people need to know that they worked X hours @ $15/hour and should be paid 15X. Otherwise they will never know if they were ripped off or be able to plan for the future.

shafoshaf··on Did an NYU professor get fired because students hate organic chem?
How does one get an A on that test, since grades are important as people move to jobs and graduate degrees? How can I compare an A from the University of Everything is Reasonable versus one that includes the grade every student gets on the Kobayashi Maru?
shafoshaf··on SAT score distributions in Michigan
I was surprised that Asians only make up 4.6% of the total students, where Whites are nearly 69%. I'm not sure that we can make too many observations about Asians when the sample is so low.

Might be interesting to see how those demographics compare in CA where Asians are 16.91% of the population. (https://worldpopulationreview.com/state-rankings/asian-popul...)

I agree it isn't "race." However, there are groups of people who have similar characteristics where it might be beneficial to look at the group as a whole not just individuals. For example, it may be that a certain group of people, with a common background and in a particular geography have specific notions about whether they trust that education will work or that health care will be honest. It might help to look at those communities and have discussions about what can be done for them at large. I think it would be very difficult to only look at individuals. Obviously, we then get the problem of group labels and stereotypes being used for malicious purposes...

When you talk about some of the least served communities, there is a lot of moving from school to school as people move from one housing solution to another. My wife taught in public school and out of the 35 students in a class there might have been a third to 40% who stayed with her the whole semester. She would have two extra pages of names of students who came and went throughout the year.
shafoshaf··on Raft Is So Fetch: The Raft Consensus Algorithm Explained Through Mean Girls
>>When Regina shows up to lunch wearing sweatpants on a Monday she is dramatically booted from her role as leader of the Plastics

But, isn't she still part of the clique? Therefore, when Cady takes over as Queen Bee, there are now 4 in the clique and Cady will require 2/4 votes for consensus, which is the same as before (2/3). But if there is a third coup, it would then take 3/5 votes. That is unless Regina and Cady are kicked out as well as knocked down.

shafoshaf··on Failing Intro Economics
They may have been exposed to great teaching, but do they recognize it? Asking people how they feel about the learning without an objective criteria to measure their performance could be a recipe for a local maximum.
shafoshaf··on Ask HN: Lost in My Career
The way I put it is that it's a shame to ruin a perfectly good hobby with a job.

My background is all computer science and I work building those CRUD apps. However, my hobby is mobile dev, simulations, and hacking. I don't think I'd be happy doing those things with bosses and customers telling me what they need.

shafoshaf··on Why does everything on Netflix look like that?
>>> Johnathan Strange and Mr Norrell I had forgotten about that show. It was really great! Just 2 cents.

Sandman definitely has a feel that will date it. I am enjoying it (having the Sandman go to hell is a great plot mechanism) but I don't know about the re-watchability. I don't think this is limited to Netflix, I feel like there is definitive 2020's mise en scene, which I don't think Truffaut or Godard would approve of.

shafoshaf··on Good conversations have lots of doorknobs
We have a no "Thank You's" policy because it re-opens the ticket which is really annoying.
shafoshaf··on Is DALL-E 2 ‘gluing things together’ without understanding their relationships?
That last bit about the horse is pretty loaded. Knowing what a giraffe is means knowing that it is a mammal, has a blood system, eats leaves, reacts certain ways to certain stimuli, etc... That is a lot more than just knowing what it looks like. Image recognition is not the same a relationships or knowledge.
shafoshaf··on What I learned trying to classify abortion access across the rich world
>>>Barring harm to the mother (which ultimately is dangerous to baby), I see little argument to allow abortion in a logical sense.

Does that harm extend to psychological harm, such as incest and/or rape?

shafoshaf··on Mermaid: Create diagrams and visualizations using text and code
One thing I didn't see mentioned here is that mermaid makes creating charts programmatically very simple. We have a ton of workflows that are basically FSAs. We use Mermaid to create visuals of the workflows on the fly. Change it in code and the docs auto update.

Also, VisualStudio.com supports Mermaid as well.

shafoshaf··on Is everything falling apart?
Incentives are already here. Tulsa offers $10K to move there.
shafoshaf··on Simple Ways to Be Less Divisive (2021)
I agree. Joking less should be defined as only make jokes that everyone can appreciate. They don't have to think it is funny, but they should not be at anyone's expense.
shafoshaf··on Ask HN: What book changed your life?
Getting Things Done By David Allen. I feel like everything I do is a decision and not a reaction now.
shafoshaf··on We Are Less Educated Than We Think
I feel like that comment is that there is a difference between vocational training and classical liberal arts. It isn't that one is better than the other. But when vocational training is packaged at a college as though it is pure intellectualism, there is a disconnect between what was accomplished and what was promised.
