People often use Lambda School as a poster child for using nocode tools; we used (and use) a lot, which lets everyone (including nontechnical ppl) ship very quickly. Great!

BUT

If nocode changes affect your data model, you’re creating outrageous amounts of technical debt.
For example, if someone can notice data they’re missing and are able to quickly add columns to a base, that’s awesome. But without understanding the technical implications of doing so everything can break.

There’s not really a safeguard against that.
“But you can just move over what you’re doing to a normal database whenever you want.” Well, kind of. As long as

1. You can freeze all of the data while you migrate (unlikely)

And

2. The data model still makes sense (unlikely)
In retrospect I wouldn’t start doing anything in them without a well-architected data model that only select people can change, and ideally a team turning the nocode into traditional code as quickly as possible.

With great power comes great potential for technical debt.
Oh, and if you are one of the many people over the years who have emailed me saying, “Will programmers all lose their jobs as nocode becomes more prevalent?”

Hahahahahaha no.

Have been waiting to be able to publicly talk about this for a while now:

Lambda School is developing a blockchain course to turn all you engineers and developers into crypto engineers in the hours after work.

Sign up to learn more: lambdaschool.com/learn-blockcha…
For those looking to help develop curriculum, teach, hire from, or sponsor scholarships for the course, email blockchain@lambdaschool.com
I’m really, really excited to bring Lambda School’s world class instructional design, curriculum development, and experiential learning expertise to the crypto space.

Books I finish last week:

(Being off the grid makes you wrap up the books you've been meaning to finish for some time).
Amazon Unbound: 2/5 stars.

This is what happens when an author both has a boring narrative and is determined to shoehorn absolutely everything into it.

Such a wasted opportunity. Disappointed. Mediocre in every way.

Project Hail Mary: 5/5 stars.

I have no idea why this book was so much fun, but it was really, really good. The science was clever, the story was great.

In 1984 a researcher named Bloom found that students learning mastery-based and with one-on-one mentorship perform two standard deviations better than those in a conventional classroom.

Incredible to know, but too expensive to do anything about, so nothing changed.
We’re now in the early days of software that not only mimics 1-on-1 mentorship and mastery-based learning for cheap, but actually *surpasses* traditional mentorship.

We’re entering a completely new world where kids in classrooms (even expensive ones) will be left behind.
I’m talking to schools concerned about figuring out what to do when 13-year-olds have completed High School at an advanced level with perfect standardized test scores.

Unbelievable.

The median debt of graduates from the program is $181,000.

The median income is less than $30,000/yr.

Questions:

1. Shouldn't students be more careful?

Yes, obviously.

2. Why does the government provide unlimited debt to a program with these outcomes?

Yes, terrible idea.

3. Why does a school with an $11.26 billion untaxed endowment not care about student outcomes?

🤔🤔🤔
Reminder:

If you owe $180k in debt, your interest payments alone are probably going to be north of $10k/yr.

Compared to your $30k/yr salary.

AND THAT'S BEFORE YOU TOUCH PRINCIPAL.

Many of these people will die in debt. Massive payments for life. For two years of film school.

Look like judge threw out FTC monopoly cases against Facebook.

Seems right, legally.

I have no idea how you would prove that Facebook has monopoly power in "social networking services" amongst 10,000 competitors.
“The FTC’s Complaint says almost nothing concrete on the key question of how much power Facebook actually had, and still has, in a properly defined antitrust product market."
"It is almost as if the agency expects the Court to simply nod to the conventional wisdom that Facebook is a monopolist.”

Ouch.

Virtually everyone I talk to misunderstands how ISAs work.

I’ll often see people say, “Lambda School costs $30,000.” Or “120 Lambda grads hired = $3.6 million.”

If only!

Here’s a breakdown in more detail.

ISAs are *dramatically* more student-friendly than loans.
Let’s take a traditional school.

100 students enroll, tuition is $30k, you book $3m in revenue.

The average student will actually pay *far more* than $30k net/net, although that goes to the lender.

Some students will default on loans, so interest covers that as well.
So while “tuition” was $30k if you take 100 students paying that tuition the total they’ll pay will be something like $37k on average, depending on interest rate etc.

ISAs work in the opposite direction.
