wanderingmoose··on Airlines lobbying FAA to have only one pilot in the cockpit
During any incident, the current CRM is one pilot flies the plane while the non-flying pilot runs the check lists. I hope the single pilot is good at multi-tasking.

(* I am not a commercial pilot but I've watched enough Mayday/Air Accident Investigations to get interested in the FAA publications on CRM. Interesting read. Active work was being done ~20 years ago in this area.)

wanderingmoose··on Apple Rankings
My favorite description of a Red Delicious apple was from Mitsuwa (japanese grocery store in the US): "Looks nice, flavorless. Ok in salads"

Growing up, I really liked Winesaps from a local orchard, but those were rated "Horse Food" on this list. To each their own, I guess.

wanderingmoose··on CRISPR cancer trial success paves the way for personalized treatments
To put this in perspective, a family member was treated for leukemia and our billed* medical expenses hit $300,000 in the first 2 weeks of treatment. This included the initial hospitalization, attempted install of PIC line, install of broviac catheer. And secondary hospitalization in hepa controlled room due to other illness during an immuno compromised period.

The standard treatment continues for ~2.5 years so this was only a small portion of the bills we received.

*obviously what is paid by insurance + out of pocket is very different, but that level of billing is insane. Also you really don't want to be fighting insurance and the medical center over billing while your family is undergoing cancer treatment.

This was at UCLA

wanderingmoose··on The US will finally allow adaptive beam headlights on new cars
Caltrans had pilot program in the mid-1990's running self driving cars that used magnets embedded in the road. They would run "caravans" of five-ish vehicles driving almost bumper to bumper. This was tested on the car pool lanes on sections of a highway between los angeles and san diego.

This was a partnership between caltrans, the college of engineering at uc berkeley amongst others.

Unfortunately I can find any readily available links, but all of the data should be public. I'm only aware of this because I worked w/ some of the technical groups on the project (very tangentially involved).

I know the magnets were always considered a problem (cost/effort), but there weren't other options at the time, as computer vision was too computationally expensive at the time.

wanderingmoose··on Ask HN: A math study program?
+1 What I find really useful about these books is they allow self-teaching. (in my case a 13 year old kid) The books follow a methodology of presenting problems and having you try to solve them before walking you through the explanations. The chapters build up to "challenge problems" which are carefully crafted to require you to apply what you've learned from the current and earlier chapters. Most of the challenge problems are lifted from math competition problems (with citations), but their use is very well curated.

We are using the printed books, but there are online resources available.

wanderingmoose··on Larry Ellison’s company blocked Lanai Beach from public access in Hawaii
Try searching for "sand wheelchair" and see what people who need wheelchairs use when they go to the beach. I had a bud go through a terminal illness that left him paralyzed for the last 6 months of his life. He spent most of that at the beach in a sand wheelchair. Accessibility is important.
wanderingmoose··on America’s stealth aircraft you've never heard of

wanderingmoose··on Countersteering
Keith Code (author of twist of the wrist) has a bike with fixed handle bars that he lets you ride as part of his superbike track/race school. It is really eye opening on how little control you have without countersteering.

wanderingmoose··on Campus College of Letters and Science plans to limit high-demand majors
I strongly agree with you.

I went to berkeley in the 90's. Tuition was ~$2k (usd) per semester. I lived in a shared house for $300/month. I paid for everything out of pocket by working for a campus job (which paid $8/hour vs $5/hour minimum wage). So I was lucky and walked away with no debt.

I feel for the current generation that will need to take on debt if they feel they need a college education, and I know the amount I've been saving for my kids.

I can't change anything about the monetary policy that allowed student loans to be so large. But I do try my best to do outreach and recruiting from candidates with non-standard backgrounds and who didn't come from one of the big CS schools.

wanderingmoose··on Campus College of Letters and Science plans to limit high-demand majors
As a mid-90's graduate who started in chemistry and accidentally found my way to computer science... Oof. The promise of a well rounded education where you can explore and find out for yourself what you enjoy and where you want to study no longer exists.

I took CS classes because I wanted something fun to do outside of what I was officially studying. About the time I finished up, UCB was already limiting upper division classes to CS majors only. And this was thirty years ago.

I ended up in my career because I married the thing I thought I wanted to do (chem) with the thing I really enjoyed and was good at (programming). I met a lot of grad students who wanted help programming and I got to do a lot of cool work with different research groups in chem/phys/bio that did protein folding, data visualization, etc. I ended up getting a job at Industrial Light and Magic because I had a lot of experience programming OpenGL on Irix(SGI).

Where is the room for that kind of experience now? You need to test into the major before you even enter campus? I guess the college experience is getting a piece of paper stating that you can jump through a set of hoops.

This is disappointing. I've been fortunate enough to work in an industry that combines art and tech and know the benefits of working with people who come from a variety of backgrounds and expertise. I want to live and work in a world where you don't need to match an algorithm to have a chance. And unfortunately, many people conflate a university degree with that chance.

wanderingmoose··on EA: The Human Story (2004)
I was part of both as well.

I don't condone any of EA's behavior at the time, but the lawsuit benefited the lawyers way more than the artists and developers. I wish there was a resolution to the situation that allowed EALA to continue as a major studio. The talent there was amazing. Some of the blue sky projects that never made it to production were really interesting.

Unfortunately -- lawyers got paid. EA made some rule/structure changes. And EALA lost most of its square footage to a 24 hour fitness. Makes me sad everytime I drive by.

wanderingmoose··on Xbox 360 Architecture
Here's a good explanation of some of the issues w/ common programming patterns at the time colliding with the 360 design. This was a huge problem with the initial ports of older game engines to the 360 that required a lot of rewrites to achieve ok performance.

wanderingmoose··on Ask HN: What game do you wish existed?
One game that was announced and then cancelled was https://en.wikipedia.org/wiki/List_of_canceled_Command_%26_C...

It was similar to what you are talking about. There was an RTS aspect with a tactical view where you ordered groups of units around, and an FPS aspect where you fought as an individual.

The gameplay was based around your tactical units being under balanced against the enemy, so you would have to choose where and how to use yourself as the superweapon to achieve the level objectives.

I was a developer on the game team which had representatives from the RTS and FPS teams (CnC and Medal of Honor). The first day you were on the team you had to play the lo-fi prototype which had the basic mechanics in place. It was frantic, exhausting, frustrating, and incredibly fun.

Obviously I can't talk about why it was cancelled, but if you look at the business environment and economy in the first couple of years after the xbox360 and ps3 were released, you can get a good idea.

I really wish that game had been finished and released as it was originally conceived.

wanderingmoose··on Case for the Grumman F6F Hellcat being the greatest fighter of the 2nd World War
If this article was interesting for you, I'd suggest Greg's Airplances and Automobiles youtube channel.

https://www.youtube.com/channel/UCynGrIaI5vsJQgHJAIp9oSg

Rabbit Hole warning: The channel features discussions on many different aspects of plane design and performance, but focuses heavily on primary sources. You will learn a lot about what NACA was doing at the time. I'm not really a plane person, but this channel was fascinating.

wanderingmoose··on Facing housing crisis, L.A. voters back duplexes in single-family neighborhoods
My understanding is you are already allowed to build an ADU (additional dwelling unit) due to state laws.

What I've seen in my city (LA adjacent) is the city can find really creative ways of making adding an ADU very expensive. On my block the same contractor built 2 different ~500 sq ft units on two different lots. They both were a garage tear down replaced by a 1 bedroom unit above a garage.

The first unit was done right after the law change allowing ADUs, and cost ~140k. The second, started 18 months later was ~270k and the owner had to pay for things like repaving the ally and upgrading the sewers.

So even the small steps are being impeded.

wanderingmoose··on Walmart unveils low-price analog insulin amid rising diabetes drug costs
It is variable. But I'm 220, 6'6" I use ~24 units per day basal rate (continuously pumped, amount programmed over 24 hours) And 1 unit of insulin per 15 grams carbohydrate. I usually average ~50 units per day.

Additionally my pump (tandem x2) has a lot of loss due to their loading system. For 300 units loaded, you get 250 deliverable units. Reloads happen about every 5 days.

For use per month, I have 2 vials per month prescribed.

If you are thinking about cost: pump insertion sets and continuous glucose monitoring sensors are all very expensive as well.

wanderingmoose··on Ask HN: What are some books where the reader learns by building projects?
+1 This book is excellent. Going through it w/ my daughter as a learning project now. I've worked on renderers in the games and vfx industries, and this is a very satisfying and relatively easy introduction.

Once finished, you can jump in to PBRT https://pbrt.org/ which has a new update coming out for rendering on gpu.
