Jeff Atwood: Stack Overflow and Coding Horror | Lex Fridman Podcast #7
I'm just like, I need to apply my programming concepts I already
https://karpathy.ai/lexicap/0007-large.html#00:56:16.600
Jeff Atwood: Stack Overflow and Coding Horror | Lex Fridman Podcast #7
know to Ruby.
https://karpathy.ai/lexicap/0007-large.html#00:56:19.140
Jeff Atwood: Stack Overflow and Coding Horror | Lex Fridman Podcast #7
Well, so there's a question that's really interesting.
https://karpathy.ai/lexicap/0007-large.html#00:56:20.360
Jeff Atwood: Stack Overflow and Coding Horror | Lex Fridman Podcast #7
So looking at Ruby, how do you go about learning enough
https://karpathy.ai/lexicap/0007-large.html#00:56:23.280
Jeff Atwood: Stack Overflow and Coding Horror | Lex Fridman Podcast #7
that your intuition can be applied, carried over?
https://karpathy.ai/lexicap/0007-large.html#00:56:26.840
Jeff Atwood: Stack Overflow and Coding Horror | Lex Fridman Podcast #7
That's what I was trying to get to.
https://karpathy.ai/lexicap/0007-large.html#00:56:29.640
Jeff Atwood: Stack Overflow and Coding Horror | Lex Fridman Podcast #7
It's like what I realized, particularly when I started
https://karpathy.ai/lexicap/0007-large.html#00:56:30.360
Jeff Atwood: Stack Overflow and Coding Horror | Lex Fridman Podcast #7
with just me and Robin, I realized if I bother Robin,
https://karpathy.ai/lexicap/0007-large.html#00:56:31.600
Jeff Atwood: Stack Overflow and Coding Horror | Lex Fridman Podcast #7
I am now costing us productivity.
https://karpathy.ai/lexicap/0007-large.html#00:56:34.840
Jeff Atwood: Stack Overflow and Coding Horror | Lex Fridman Podcast #7
Every time I go to Robin, rather than building our first alpha
https://karpathy.ai/lexicap/0007-large.html#00:56:37.120
Jeff Atwood: Stack Overflow and Coding Horror | Lex Fridman Podcast #7
version of discourse, he's now answering my stupid questions
https://karpathy.ai/lexicap/0007-large.html#00:56:42.160
Jeff Atwood: Stack Overflow and Coding Horror | Lex Fridman Podcast #7
about Ruby.
https://karpathy.ai/lexicap/0007-large.html#00:56:45.540
Jeff Atwood: Stack Overflow and Coding Horror | Lex Fridman Podcast #7
Is that a good use of his time?
https://karpathy.ai/lexicap/0007-large.html#00:56:46.040
Jeff Atwood: Stack Overflow and Coding Horror | Lex Fridman Podcast #7
Is that a good use of my time?
https://karpathy.ai/lexicap/0007-large.html#00:56:47.600
Jeff Atwood: Stack Overflow and Coding Horror | Lex Fridman Podcast #7
And the answer to both of those was resoundingly no.
https://karpathy.ai/lexicap/0007-large.html#00:56:49.160
Jeff Atwood: Stack Overflow and Coding Horror | Lex Fridman Podcast #7
We were getting to an alpha, and it was pretty much just,
https://karpathy.ai/lexicap/0007-large.html#00:56:53.080
Jeff Atwood: Stack Overflow and Coding Horror | Lex Fridman Podcast #7
OK, we'll hire more programmers.
https://karpathy.ai/lexicap/0007-large.html#00:56:55.080
Jeff Atwood: Stack Overflow and Coding Horror | Lex Fridman Podcast #7
We eventually hired Neil, and then eventually Sam,
https://karpathy.ai/lexicap/0007-large.html#00:56:56.880
Jeff Atwood: Stack Overflow and Coding Horror | Lex Fridman Podcast #7
who came in as a cofounder.
https://karpathy.ai/lexicap/0007-large.html#00:57:00.240
Jeff Atwood: Stack Overflow and Coding Horror | Lex Fridman Podcast #7
Actually, it was Sam first, then Neil later.
https://karpathy.ai/lexicap/0007-large.html#00:57:02.920
Jeff Atwood: Stack Overflow and Coding Horror | Lex Fridman Podcast #7
But the answer to the problem is just
https://karpathy.ai/lexicap/0007-large.html#00:57:05.000
Jeff Atwood: Stack Overflow and Coding Horror | Lex Fridman Podcast #7
hire other competent programmers.
https://karpathy.ai/lexicap/0007-large.html#00:57:06.400
Jeff Atwood: Stack Overflow and Coding Horror | Lex Fridman Podcast #7
Now I shall pull myself up by my bootstraps
https://karpathy.ai/lexicap/0007-large.html#00:57:08.200
Jeff Atwood: Stack Overflow and Coding Horror | Lex Fridman Podcast #7
and learn Ruby.
https://karpathy.ai/lexicap/0007-large.html#00:57:11.080
Jeff Atwood: Stack Overflow and Coding Horror | Lex Fridman Podcast #7
But at some point, writing code becomes a liability to you
https://karpathy.ai/lexicap/0007-large.html#00:57:12.320
Jeff Atwood: Stack Overflow and Coding Horror | Lex Fridman Podcast #7
in terms of getting things done.
https://karpathy.ai/lexicap/0007-large.html#00:57:15.960
Jeff Atwood: Stack Overflow and Coding Horror | Lex Fridman Podcast #7
There's so many other things that
https://karpathy.ai/lexicap/0007-large.html#00:57:17.360
Jeff Atwood: Stack Overflow and Coding Horror | Lex Fridman Podcast #7
go on in the project, like building the prototype.
https://karpathy.ai/lexicap/0007-large.html#00:57:18.460
Jeff Atwood: Stack Overflow and Coding Horror | Lex Fridman Podcast #7
You mentioned, well, how do you, if you're not writing code,
https://karpathy.ai/lexicap/0007-large.html#00:57:20.800
Jeff Atwood: Stack Overflow and Coding Horror | Lex Fridman Podcast #7
how does everybody keep focus on what are we building?
https://karpathy.ai/lexicap/0007-large.html#00:57:23.120
Jeff Atwood: Stack Overflow and Coding Horror | Lex Fridman Podcast #7
Well, first, basic mockups and research.
https://karpathy.ai/lexicap/0007-large.html#00:57:25.680
Jeff Atwood: Stack Overflow and Coding Horror | Lex Fridman Podcast #7
What do we even want to build?
https://karpathy.ai/lexicap/0007-large.html#00:57:28.440
Jeff Atwood: Stack Overflow and Coding Horror | Lex Fridman Podcast #7
There's a little bit of that that goes on.
https://karpathy.ai/lexicap/0007-large.html#00:57:30.160
Jeff Atwood: Stack Overflow and Coding Horror | Lex Fridman Podcast #7
But then very quickly, you get to the prototype stage.
https://karpathy.ai/lexicap/0007-large.html#00:57:31.240
Jeff Atwood: Stack Overflow and Coding Horror | Lex Fridman Podcast #7
Like, build a prototype.
https://karpathy.ai/lexicap/0007-large.html#00:57:32.800
Jeff Atwood: Stack Overflow and Coding Horror | Lex Fridman Podcast #7
Let's iterate on the prototype really, really rapidly.
https://karpathy.ai/lexicap/0007-large.html#00:57:33.760
Jeff Atwood: Stack Overflow and Coding Horror | Lex Fridman Podcast #7
And that's what we do with discourse.
https://karpathy.ai/lexicap/0007-large.html#00:57:35.920
Jeff Atwood: Stack Overflow and Coding Horror | Lex Fridman Podcast #7
And that's what we demoed to get our seed funding
https://karpathy.ai/lexicap/0007-large.html#00:57:36.840
Jeff Atwood: Stack Overflow and Coding Horror | Lex Fridman Podcast #7
for discourse was the alpha version of discourse
https://karpathy.ai/lexicap/0007-large.html#00:57:38.960
Jeff Atwood: Stack Overflow and Coding Horror | Lex Fridman Podcast #7
that we had running and ready to go.
https://karpathy.ai/lexicap/0007-large.html#00:57:42.320
Jeff Atwood: Stack Overflow and Coding Horror | Lex Fridman Podcast #7
And it was very, it was bad.
https://karpathy.ai/lexicap/0007-large.html#00:57:43.800
Jeff Atwood: Stack Overflow and Coding Horror | Lex Fridman Podcast #7
I mean, it was, I'll just tell you it was bad.
https://karpathy.ai/lexicap/0007-large.html#00:57:45.160
Jeff Atwood: Stack Overflow and Coding Horror | Lex Fridman Podcast #7
We have screenshots of it.
https://karpathy.ai/lexicap/0007-large.html#00:57:47.360
Jeff Atwood: Stack Overflow and Coding Horror | Lex Fridman Podcast #7
I'm just embarrassed to look at it now.
https://karpathy.ai/lexicap/0007-large.html#00:57:48.440
Jeff Atwood: Stack Overflow and Coding Horror | Lex Fridman Podcast #7
But it was the prototype.
https://karpathy.ai/lexicap/0007-large.html#00:57:50.280
Jeff Atwood: Stack Overflow and Coding Horror | Lex Fridman Podcast #7
We were figuring out what's working, what's not working.
https://karpathy.ai/lexicap/0007-large.html#00:57:51.320
Jeff Atwood: Stack Overflow and Coding Horror | Lex Fridman Podcast #7
Because there's such a broad gap between the way
https://karpathy.ai/lexicap/0007-large.html#00:57:53.740
Jeff Atwood: Stack Overflow and Coding Horror | Lex Fridman Podcast #7
you think things will work in your mind or even on paper
https://karpathy.ai/lexicap/0007-large.html#00:57:58.040
Jeff Atwood: Stack Overflow and Coding Horror | Lex Fridman Podcast #7
and the way they work once you sit and live in the software,
https://karpathy.ai/lexicap/0007-large.html#00:58:00.400
Jeff Atwood: Stack Overflow and Coding Horror | Lex Fridman Podcast #7
like actually spend time living and breathing in software,
https://karpathy.ai/lexicap/0007-large.html#00:58:03.040
Jeff Atwood: Stack Overflow and Coding Horror | Lex Fridman Podcast #7
so different.
https://karpathy.ai/lexicap/0007-large.html#00:58:05.560
Jeff Atwood: Stack Overflow and Coding Horror | Lex Fridman Podcast #7
So my philosophy is get to a prototype.
https://karpathy.ai/lexicap/0007-large.html#00:58:06.720
Jeff Atwood: Stack Overflow and Coding Horror | Lex Fridman Podcast #7
And then what you're really optimizing
https://karpathy.ai/lexicap/0007-large.html#00:58:10.800
Jeff Atwood: Stack Overflow and Coding Horror | Lex Fridman Podcast #7
for is speed of iteration, like how you can turn the crank.
https://karpathy.ai/lexicap/0007-large.html#00:58:12.380
Jeff Atwood: Stack Overflow and Coding Horror | Lex Fridman Podcast #7
How quickly can we iterate?
https://karpathy.ai/lexicap/0007-large.html#00:58:14.800
Jeff Atwood: Stack Overflow and Coding Horror | Lex Fridman Podcast #7
That's the absolutely critical metric
https://karpathy.ai/lexicap/0007-large.html#00:58:16.120
Jeff Atwood: Stack Overflow and Coding Horror | Lex Fridman Podcast #7
of any software project.
https://karpathy.ai/lexicap/0007-large.html#00:58:18.000
Jeff Atwood: Stack Overflow and Coding Horror | Lex Fridman Podcast #7
And I had a tweet recently that people liked.
https://karpathy.ai/lexicap/0007-large.html#00:58:19.160
Jeff Atwood: Stack Overflow and Coding Horror | Lex Fridman Podcast #7
And I totally, this is so fundamental to what I do,
https://karpathy.ai/lexicap/0007-large.html#00:58:20.920
Jeff Atwood: Stack Overflow and Coding Horror | Lex Fridman Podcast #7
is like if you want to measure the core competency of any
https://karpathy.ai/lexicap/0007-large.html#00:58:23.160
Jeff Atwood: Stack Overflow and Coding Horror | Lex Fridman Podcast #7
software tech company, it's the speed at which somebody
https://karpathy.ai/lexicap/0007-large.html#00:58:26.160
Jeff Atwood: Stack Overflow and Coding Horror | Lex Fridman Podcast #7
can say, hey, we really need this word in the product.
https://karpathy.ai/lexicap/0007-large.html#00:58:28.960
Jeff Atwood: Stack Overflow and Coding Horror | Lex Fridman Podcast #7
Change this word, right?
https://karpathy.ai/lexicap/0007-large.html#00:58:31.200
Jeff Atwood: Stack Overflow and Coding Horror | Lex Fridman Podcast #7
Because it will be more clear to the user.
https://karpathy.ai/lexicap/0007-large.html#00:58:32.280
Jeff Atwood: Stack Overflow and Coding Horror | Lex Fridman Podcast #7
Like, instead of respond, it's reply or something.
https://karpathy.ai/lexicap/0007-large.html#00:58:34.280
Jeff Atwood: Stack Overflow and Coding Horror | Lex Fridman Podcast #7
But there's some, from the conception of that idea
https://karpathy.ai/lexicap/0007-large.html#00:58:36.400
Jeff Atwood: Stack Overflow and Coding Horror | Lex Fridman Podcast #7
to how quickly that single word can be changed in your software
https://karpathy.ai/lexicap/0007-large.html#00:58:39.760
Jeff Atwood: Stack Overflow and Coding Horror | Lex Fridman Podcast #7
and rolled out to users, that is your life cycle.
https://karpathy.ai/lexicap/0007-large.html#00:58:42.640
Jeff Atwood: Stack Overflow and Coding Horror | Lex Fridman Podcast #7
That's your health, your heartbeat.
https://karpathy.ai/lexicap/0007-large.html#00:58:44.920
Jeff Atwood: Stack Overflow and Coding Horror | Lex Fridman Podcast #7
If your heartbeat is like super slow, you're basically dead.
https://karpathy.ai/lexicap/0007-large.html#00:58:47.320
Jeff Atwood: Stack Overflow and Coding Horror | Lex Fridman Podcast #7
No, seriously.
https://karpathy.ai/lexicap/0007-large.html#00:58:51.640
Jeff Atwood: Stack Overflow and Coding Horror | Lex Fridman Podcast #7
Like, if it takes two weeks or even a month
https://karpathy.ai/lexicap/0007-large.html#00:58:52.200
Jeff Atwood: Stack Overflow and Coding Horror | Lex Fridman Podcast #7
to get that single word changed, everybody's like, oh my god,
https://karpathy.ai/lexicap/0007-large.html#00:58:54.880
Jeff Atwood: Stack Overflow and Coding Horror | Lex Fridman Podcast #7
this is a great idea.
https://karpathy.ai/lexicap/0007-large.html#00:58:56.840
Jeff Atwood: Stack Overflow and Coding Horror | Lex Fridman Podcast #7
That word is so much clearer.
https://karpathy.ai/lexicap/0007-large.html#00:58:57.760
Jeff Atwood: Stack Overflow and Coding Horror | Lex Fridman Podcast #7
I'm talking about like a super, like everybody's
https://karpathy.ai/lexicap/0007-large.html#00:58:59.000
Jeff Atwood: Stack Overflow and Coding Horror | Lex Fridman Podcast #7
on board for this change.
https://karpathy.ai/lexicap/0007-large.html#00:59:00.700
Jeff Atwood: Stack Overflow and Coding Horror | Lex Fridman Podcast #7
It's not like, let's just change a word because we're bored.
https://karpathy.ai/lexicap/0007-large.html#00:59:01.660
Jeff Atwood: Stack Overflow and Coding Horror | Lex Fridman Podcast #7
It's like, this is an awesome change.
https://karpathy.ai/lexicap/0007-large.html#00:59:03.500
Jeff Atwood: Stack Overflow and Coding Horror | Lex Fridman Podcast #7
And then it takes months to roll out.
https://karpathy.ai/lexicap/0007-large.html#00:59:05.600
Jeff Atwood: Stack Overflow and Coding Horror | Lex Fridman Podcast #7
It's like, well, you're dead.
https://karpathy.ai/lexicap/0007-large.html#00:59:07.000
Jeff Atwood: Stack Overflow and Coding Horror | Lex Fridman Podcast #7
You can't iterate.
https://karpathy.ai/lexicap/0007-large.html#00:59:08.120
Jeff Atwood: Stack Overflow and Coding Horror | Lex Fridman Podcast #7
You can't, how are you going to do anything, right?
https://karpathy.ai/lexicap/0007-large.html#00:59:09.200
Jeff Atwood: Stack Overflow and Coding Horror | Lex Fridman Podcast #7
So anyway, about the heartbeat, it's
https://karpathy.ai/lexicap/0007-large.html#00:59:12.360
Jeff Atwood: Stack Overflow and Coding Horror | Lex Fridman Podcast #7
like, get the prototype and then iterate on it.
https://karpathy.ai/lexicap/0007-large.html#00:59:13.800
Jeff Atwood: Stack Overflow and Coding Horror | Lex Fridman Podcast #7
That's what I view as the central tenet of modern software
https://karpathy.ai/lexicap/0007-large.html#00:59:15.960
Jeff Atwood: Stack Overflow and Coding Horror | Lex Fridman Podcast #7
development.
https://karpathy.ai/lexicap/0007-large.html#00:59:19.880
Jeff Atwood: Stack Overflow and Coding Horror | Lex Fridman Podcast #7
That's fascinating that you put it that way.
https://karpathy.ai/lexicap/0007-large.html#00:59:20.480
Jeff Atwood: Stack Overflow and Coding Horror | Lex Fridman Podcast #7
So I work and I build autonomous vehicles.
https://karpathy.ai/lexicap/0007-large.html#00:59:22.480
Jeff Atwood: Stack Overflow and Coding Horror | Lex Fridman Podcast #7
And when you look at what, maybe compare Tesla
https://karpathy.ai/lexicap/0007-large.html#00:59:24.440
Jeff Atwood: Stack Overflow and Coding Horror | Lex Fridman Podcast #7
to most other automakers, the heart beat for Tesla
https://karpathy.ai/lexicap/0007-large.html#00:59:28.160
Jeff Atwood: Stack Overflow and Coding Horror | Lex Fridman Podcast #7
is literally days now in terms of they can over the air
https://karpathy.ai/lexicap/0007-large.html#00:59:34.120
Jeff Atwood: Stack Overflow and Coding Horror | Lex Fridman Podcast #7
deploy software updates to all their vehicles, which
https://karpathy.ai/lexicap/0007-large.html#00:59:38.120
Jeff Atwood: Stack Overflow and Coding Horror | Lex Fridman Podcast #7
is markedly different than every other automaker, which takes
https://karpathy.ai/lexicap/0007-large.html#00:59:41.360
Jeff Atwood: Stack Overflow and Coding Horror | Lex Fridman Podcast #7
years to update a piece of software.
https://karpathy.ai/lexicap/0007-large.html#00:59:46.040
Jeff Atwood: Stack Overflow and Coding Horror | Lex Fridman Podcast #7
And that's reflected in everything
https://karpathy.ai/lexicap/0007-large.html#00:59:49.160
Jeff Atwood: Stack Overflow and Coding Horror | Lex Fridman Podcast #7
that's the final product.
https://karpathy.ai/lexicap/0007-large.html#00:59:52.120
Jeff Atwood: Stack Overflow and Coding Horror | Lex Fridman Podcast #7
That's reflected in really how slowly they
https://karpathy.ai/lexicap/0007-large.html#00:59:54.840
Jeff Atwood: Stack Overflow and Coding Horror | Lex Fridman Podcast #7
adapt to the times.
https://karpathy.ai/lexicap/0007-large.html#00:59:57.280
Jeff Atwood: Stack Overflow and Coding Horror | Lex Fridman Podcast #7
And to be clear, I'm not saying being a hummingbird
https://karpathy.ai/lexicap/0007-large.html#00:59:58.200
