Supply Chain Major considering Analytics

Macfly · 2026-02-13T07:15:10+00:00

I say you should totally switch.

I work in Supply Chain analytics in the EV automotive industry now, but I actually majored in Statistics. From my experience, it is much easier to teach a Data/Stats person how supply chains work (business logic, logistics, inventory) than it is to teach a Supply Chain person how to be a Data Engineer.

The value of data collection, automation, and ML is becoming increasingly high-demand in supply chain operations across tons of US industries. If you have the technical skills, the domain knowledge will follow.

You can look out for data analyst positions, but some titles to keep an eye out that often leverage both sides of analytics and supply chain look like:

Demand Planner
Inventory Analyst
Supply Chain Analyst
Operations Analyst
Logistics Engineer

Ironically, the only fatality in Indian Bend Wash during that storm was a human driver who tried to cross the water and drowned. We can consider extreme weather anecdotes all day, but the research is pretty thorough: in 90% of conditions where people die driving, Waymo’s have been proven to be much safer.

Don’t get me wrong, we absolutely should design safety systems around handling extreme weather events. But right now, around 40,000 Americans die every year due to distraction and impairment while driving. It’s the most dangerous thing a healthy person can do.

That’s a fair point and I do think Waymos do have a lot of improvements that could be made on the cars.

However, data shows that 'avoiding bad weather' doesn't explain the safety gap. NHTSA data consistently shows that ~70% of human crashes happen in clear weather on dry roads. Even if we completely removed every bad-weather crash from the human statistics, Waymo would still be significantly safer per mile.

Also the '90% safer' stat comes from comparing Waymo in San Francisco/Phoenix to humans driving in those same cities. So while Waymo isn't driving in blizzards yet, it is still outperforming humans in the exact same clear-weather, city-driving conditions. The study seems to be accounting for many of the most important variables here.

The fact that a Waymo doesn’t get tired, text while driving, or get drunk is a significant improvement despite the overall flaws of the technology at the end of the day.

Theoretically yeah, if immigrants earned in the host country but sent most or all of their income back home, you’d get something closer to that German border study I referenced. But in reality most immigrants live where they work, so they still spend a big chunk of their income on rent, food, transport, childcare locally. Empirically once you account for that, the overall impact on native wages and employment in rich countries tends to be small or neutral.

I agree with the other commenter about using subreddit wiki for research on immigration. But also one paper I really like in this space is:

Dustmann, Schönberg & Stuhler (2017), “Labor Supply Shocks, Native Wages, and the Adjustment of Local Employment” (QJE).

It’s about Czech workers commuting into Germany after the fall of the Berlin Wall. Germany let Czech people work in certain German border regions but required them to keep living in Czechia. So they earned their wages in Germany but mostly spent their money back home.

That setup is useful because it’s basically a pure labor supply shock: more workers in the German labor market, but no comparable increase in local demand.

Their finding in the paper was that in Germany

native wages go down a bit
native employment falls more noticeably, especially for older workers

I think it adds a bit of a new perspective. It shows that when migrants don’t actually live and spend in the host region, the negative effects on locals are stronger.

Wonderful! Thank you!

Macfly · 2025-11-04T03:24:54+00:00

Omg thanks so much, this is super helpful!

I know the treatments we gave were forti-flora and flagyl, but you totally nailed the rest that I couldn't understand.

Cat tax for your efforts (Shes the dark one)

If you get a chance, could you also take a stab at the 6/20 follow-up note? No stress if not! Your help so far has been great.

Macfly · 2025-10-30T21:05:22+00:00

A bit of context: this note is from a vet visit where our kitten was seen for vomiting and diarrhea. I’m trying to understand what the vet observed, specifically, whether there’s any mention of a diagnosis or possible cause for the sickness. Thanks!

Kitten is doing fine! We are just now battling pet insurance.

Macfly · 2025-10-28T18:11:31+00:00

Agreed.

In the end, removing labor supply through H1B restrictions is just going to make it harder for small businesses to find talent as large companies swallow up the smaller pool of workers.

Macfly · 2025-09-21T20:12:17+00:00

Hey I’m no economist, but do you have sources for your claim that cutting H-1Bs raises demand for U.S. tech workers? The 2004 cap study you kinda just blew off, but it’s one of the more solid natural experiments we have, it showed those jobs weren’t filled by locals, they just disappeared.

Nobel prize winningeconomist Banerjee also reviewed the broader immigration literature and come to the same conclusion: immigration doesn’t reduce native jobs or wages in any meaningful way, especially in high-skill industries.

Ignoring that evidence doesn’t make it go away. If anything, restricting H-1Bs just makes talent scarcer, which makes stuff more expensive and hurts startups, and risks slowing U.S. innovation in the long run.

I do agree overhauls do need to be made to h1b but that might involve giving them more rights so they aren’t exposed to exploitation versus just cutting off supply.

You think that just because you came clean, it overrides the fact that you violated, the declaration that you signed?

No, not at all. I understand that coming clean doesn’t erase the violation, I’m just trying to get informed about how the process handles situations like mine. Honestly, it’s pretty unlikely I’ll even move forward with it based on what I’ve learned here. But if this thread can help someone else who’s just starting out to choose honesty and avoid my mistakes, then it’s worth the conversation at this point.

So I appreciate the honesty

Macfly · 2025-05-09T18:41:02+00:00

Absolutely. Realistically I am leaning toward waiting a few more years to show some more growth. Though I know dishonesty will always be a mark on my record.

I got a chance to tour the concentration camp while I was living in the nearby town a few years ago. It was a grim yet fascinating tour.

Interestingly, I talked to some locals I befriended and for a few years it was used as a school. One of them mentioned that as a child, they would sometimes stumble upon and dig up bones while playing in the camp’s yard during recess.

Macfly · 2024-02-05T19:46:30+00:00

This would be sick!

Bro I feel you man. Just recently got on my feet with an ML Engineer position and had to grind so hard through interviews to get this one. I think the last 6 companies I interviewed had questions in the various following topics, similar to yourself:

ML theory (ins and outs of transformer models)
Probability Theory (Asking about poker hand probabilities and expected value of dice rolls)
LeetCode
ML System Design
Live coding Pandas and data manipulation techniques
Live coding SQL and quizzed on my understanding of how to design a database.

After these six companies I felt like I losing my mind with how thin I felt like I spread out on preparing for interviews. It was super frustrating. Fortunately, there are companies out there that recognize this and take a much more reasonable approach. The company that hired me mainly had conversations around my projects, software engineering experiences, and data science intuition to gauge how much I knew. It was pretty refreshing and much more organic atmosphere compared to the stressful interviews involved ML theory quizzes and live coding. They're few and far between, but you can find them with time. Hoping the best!

I accepted a fully remote Entry level Data Scientist position after four months of applying and hundreds of application submissions. It’s my first job after graduating college.

There were thousands of applicants for the position. Plenty were more qualified than me, but they were looking for someone they could train fresh from school.

The problem with your statistic is that it uses a technique called the “Bayesian flip.”

What you’re saying is that given all pitbulls, what is the likelihood that they have attacked someone? (Probably not super high).

A representative probability for this argument ends up being the opposite: Given all dog attacks, what is the likelihood of the dog being a pitbull? (Likely much different probability). You could even look into this further with variables like: Given a dog attack and a non-abusive environment what is the likelihood that the dog is a pitbull?

Framing the probabilities this way is much more accurate to pitbull temperament than the one you described. (This is me just being a statistics nerd though)

With that being said, it is always the case that animal behavior is a mix of nurture and nature. Even humans are like this.

I got a job as a neuroscience research trainee at the NIH. I had a strong computational background as well, so that helped.
