heymijo··on The Egg (2009)
I went into Project Hail Mary knowing nothing beyond it was from the author of The Martian. It may have been the most enjoyable reading experience I've ever had.

My guess is that they experienced something like this and needed larger sized normal shoes to accommodate the more natural foot shape.

heymijo··on Rippling sues Deel over spying
The complaint goes into a lot of detail. Start at page 16 and read through at least page 23 if you want to understand what Ripling could discern from the spy's Slack usage.

> In part to ensure that the confidential information in Rippling’s Slack channels is used only for authorized purposes, Rippling employees’ Slack activity is “logged,” meaning every time a user views a document through Slack, accesses a Slack channel, sends a message, or conducts searches on Slack, that activity (and the associated user) is recorded in a log file.

heymijo··on Building Effective Agents
We've worked with dozens of teams building LLM agents across industries. Consistently, the most successful implementations use simple, composable patterns rather than complex frameworks.

This explains the Manus hype. Both why it didn't work (too complex) and why there was so much hype (thinking things had significantly advanced beyond this).

Maybe advancements will make Manus-esque systems functional but for now it seems like adding brittle processes on top of one another.

heymijo··on Pentagon to give AI agents a role in decision making, ops planning
For Scale AI at least. My armchair assessment is that Alexander Wang and Scale AI don't have a venture scale business yet has a $13.8 billion valuation to live up to. I think Wang knows this and so he's pivoting to defense where the outcomes will be squishy to non-existent and the contracts are guaranteed.
heymijo··on The Tyranny of Structurelessness (1970)
This was a key insight Alexander Hamilton had after growing up in the West Indies seeing the worst of slavery and then moving to the American colonies and receiving a classical education.

The American democracy he sought to co-create was one that could reign in humanity's worst impulses while enabling our better ones.

heymijo··on America's new millionaire class: Plumbers and HVAC entrepreneurs
> often employing fear tactics and sales quotas to incentivize upsells

This already happens. The most common AC repair needed is a new capacitor. It's a $20 part.

Call your dad's business, you probably get a quote for $100-ish and it's fixed in ten minutes.

Call a PE owned shop and they are likely to tell you that your entire system needs replaced. Quote $5-$8k.

Reports like this are already common place, and the roll-ups of former small-businesses in industry like HVAC that the PE people celebrate will only make this worse for customers.

heymijo··on General Motors cutting salaried tech workforce to 'prioritize investments'
Interesting considering GM's announcement to move away from Apple Carplay to a proprietary tech system. Looking for updates I found a few articles that smell like submarines [0], even though the contents don't necessarily match the headlines IMO [1] [2].

Headline: GM’s New Car Software Is Good Even Without Apple’s CarPlay

Details: A GM representative initially guided me through the process of syncing my iPhone over Bluetooth to handle calls and texts, and it requires about 16 clicks to grant the necessary privacy permissions. My wife, accustomed to one-click CarPlay access in our Subaru, later went through this on-boarding herself and found it annoying and complicated without the guidance I had.

Logging into apps is done via QR codes, similar to how you’d sign in to streaming services on a modern TV. Once all that’s set up, though, the experience is pretty smooth.

I'm also reminded of Ha Phan, a thoughtful designer who I'm familiar with via Twitter. She went to Ford for a brief stint a few years ago and left when seeing their tech rhetoric didn't match up with their BigCo bureaucracy [3]. Ford is obviously not GM, but I wouldn't expect any different from a legacy automaker.

heymijo··on Panic at the Job Market
TL;DR on Section 174, Research & Experimentation costs went from being fully deductible in the year incurred to being deductible over a 5 year period.

Larger tax bills and a tightening on what roles/activities are deductible as R&E are likely what OP is pointing at with his comment.

To the best of my non-inside baseball research, Section 174 changes were simply one part of a package of revenue generating measures to offset the large tax cuts from the broader tax act they were a part of.

The changes came from The Tax Cuts & Jobs Act of 2017 that was introduced to the House of Representatives by Congressman Kevin Brady (R) Texas. The bill passed both houses of Congress along party lines. Then President Trump signed the bill into law. Section 174 changes did not take effect until 2021.

heymijo··on Boeing to plead guilty to criminal fraud charge stemming from 737 MAX crashes
Regarding the "Can/should a CEO or officer be held liable?" dialogue, there is already at least one precedent.

The 2002 Sarbanes-Oxley (SOX) Act:

> The law states that if top corporate executives knowingly sign off on a false financial report, they’re subject to a prison term of up to 10 years and a fine of up to $1 million, with penalties escalating to 20 years and $5 million if their misconduct is willful. [0]

Now, would it work? The linked article details reasons that make it challenging in the SOX context.

"I wish they'd implement branching conversations like in ChatGPT"

Can you say more about this?

I Google'd and I'm not finding much. I asked ChatGPT and its response was not the assumption I held about what "branching" meant [0].

heymijo··on Fast Crimes at Lambda School
Hi DANmode, I'm obviously not OP, but I am a teacher who has gained a broad understanding of the field from practice and research.

One thing about feedback this is counterintuitive is that, students are generally very bad at understanding what actually helps them learn. When I say learn I mean gain a conceptual understanding and procedural fluency in whatever they are learning that sticks with an ability to appropriately transfer that knowledge beyond the context they've seen it in.

So unfortunately when a student says "that was great!" research has found that to be negatively correlated with learning.

If you want to delve into a study that talks about this and what effective teaching looks like in the long-term I really recommend this study done at the US Air Force Academy [0].

It is the closest thing I have seen to a gold standard study in education where a lot of research is dubious at best:

Look at what Carrell and West handed us with this study:

- 7 year study at the US Air Force Academy - 10,534 students - 421 faculty members - 30 core courses, all standardized (math, science, social science, humanities, and engineering) - Random assignment of students to professors in initial course and follow-on courses

OP mentioned The Phoenix Project [1]. It's The Goal applied to IT.

One key issue the protagonist has to overcome is how to address the issue of an endless backlog.

heymijo··on I should have loved biology (2020)
Tremendous comments in this thread that exemplify something I enjoy about HN, generative consumption. That's a fancy way of saying certain posts and comments get my mental wheels spinning, which I can transfer to whatever else I'm doing for the day.

Five minutes here for the blog, your comments, this reply, then I'm out and likely more productive than I was 6 minutes ago.

I had the same issue using Firefox on MacOS.

DNS over HTTPS is enabled by default and was at the root of my problem. I needed to add these sites to the exception list: archive.is, archive.today, archive.ph

That got me out of captcha purgatory.

heymijo··on A carbohydrate revolution is speeding up pro cycling
>"Riders are able to eat so many carbohydrates on the bike now, almost twice as much as before."

>“But what has changed is the way riders get their glycogen fix. New formulations from nutrition brands like Maurten, Precision Fuel and Hydration, and Science in Sport means the age-old carb “ceiling” of 60-90 grams per hour has been blown into another orbit.” “Consumption thresholds have been shifted thanks to “hydrogel” delivery models and new glucose-fructose ratios that ensure what goes down, stays down.”

I would have liked to see some actual details about the carbohydrate changes that have made the increased tolerance so much larger.

I looked at the three brands mentioned and the actual carbohydrate sources listed were tried and true things like maltodextrin [1], maltodextrin/fructose [2], and glucose/fructose [3].

I thought I might see something like highly branched cyclic dextrin. Since it doesn't seem to be any new form of carbohydrate, I'm curious what ancillary ingredients and/or ratios are proving to be the difference maker(s).

heymijo··on Product Strategy in the Age of AI
Might be worth looking at the limiting factors that caused the delay between iPhone (2007) and the advent of Uber, et al.

Then overlay that with the limiting factors for AI/LLMs.

I had a third-party logistics startup in 2007 that I would have loved to turn into Uber for shipping, but it would be at least a few years before the cell networks and ownership of smartphones reached a point where it was possible.

I don't know if there are limiting factors that will delay LLMs potential to disrupt the status quo.

heymijo··on Ford's answer to EV supply chain hell: Cheaper batteries
> In my opinion he was a net positive for the company

That opinion is well founded. In the book American Icon by Bryce Hoffman (Detroit News journalist) he chronicles that entire time period.

Mulally pulled off one of the greatest challenges, a bonafide turn around. They had a company culture that was all about individuals protecting their own interests. Mulally changed it to one where they focused on making vehicles people want and thinking about the long-term.

For example, Mulally held a weekly executive meeting and each head would give a color coded report of their domain's status (green for good, yellow for issues, red for caution). For weeks in this meeting every single executive reported their status as "green" for good. This in a fiscal quarter when Ford had a $6 billion loss! Mulally managed to change that culture, which for anyone who has work experience should speak very loudly.

heymijo··on Why don’t we have a strategy?
Any time strategy comes up I chuckle because it's Groundhog Day. Strategy discussions sometimes have no definition, sometimes lots of definitions, but never a shared definition.

Strategy is conflated with vision or mission. People use the word as a noun, an adverb, and an adjective and all the while talking past each other.

Its use across domains, history, and context all with different meanings make it rife for misunderstanding.

heymijo··on Supreme Court Overturns Roe vs. Wade
In Ohio we passed a state law demanding fair districts. The GOP led Ohio congress and governor repeatedly submitted districts that the courts struck down.

It went to a federal court who ruled the districts not fair but will let them stand for the 2022 elections.

The GOP ignored the rule of law, ignored the courts, and ran out the clock. They will cement their hold on the state in 2022.
