ckrapu··on Software Engineering Is Becoming Civil Engineering
I expect it will be popular to dogpile on this article and point out how it's wrong in all sort of ways. I don't mean to do this and appreciate the writing, but a core difference is that software engineering always strives to avoid catering to the idiosyncrasies of the time and place while civil engineering is virtually all about the quirks of the site.

I think this results in quite different cultures.

ckrapu··on Judge finalizes order for Greenpeace to pay $345M in ND oil pipeline case
My point is not that oil fails to generate revenue. Clearly it is a lucrative business. Instead, my claim is that the state economy was remarkably robust, productive, healthy, and well-optimized for middle class quality of life pre-2007.

Does it sound surprising to you that it was perfectly normal to rent a perfect acceptable two bedroom apartment in a safe town on the interstate for $300 a month and still easily find dignified, decent paying jobs without 1000 applications?

I've lived in many cities and work in tech now, and I can confidently say that, as it concerns the professions and jobs that unambiguously sustain and improve life, no community on the planet was more productive than my home state. There is more to the story than some shale.

ckrapu··on Judge finalizes order for Greenpeace to pay $345M in ND oil pipeline case
With all due respect, I disagree.

I loved the winters. I loved the people. I loved how its natural beauty was subtle and rewarded the patient, unlike El Capitan or the Black Hills. The economy was fine before oil appeared.

ckrapu··on Nvidia, Groq and the limestone race to real-time AI
I don't like this article. In particular, this section is especially poor:

> Block 1: We couldn't calculate fast enough. Solution: The GPU.

> Block 2: We couldn't train deep enough. Solution: Transformer architecture.

> Block 3: We can't "think" fast enough. Solution: Groq’s LPU.

#2 is outright wrong. Deep networks were made viable from residual layers and their refinement. #3 is also incorrect; "think" = compute so this is the same statement as #1.

Also, the "limestone" analogy is pretty weak.

ckrapu··on Rolling your own serverless OCR in 40 lines of code
I originally tried to do this on my own server but my GPU is too old :(
ckrapu··on Rolling your own serverless OCR in 40 lines of code
I wanted to let an LLM be able to grep and read through it.
ckrapu··on Rolling your own serverless OCR in 40 lines of code
I wasn't aware of dots when I wrote the blog post. This is really good to know!! I would like to try again with some newer models.
ckrapu··on We (As a Society) Peaked in the 90s
A thought I often have - older millennials and younger Gen X have a unique obligation to fix certain parts of society because we are the youngest generation old enough to remember how to operate in and enjoy a world that wasn't A/B tested into a gray, lifeless background hum.
ckrapu··on Tell HN: Current gen AI is just the epitome of error-correcting codes
From this perspective, humans are just ECC with an optimally non-zero bit flip rate for evolution.
ckrapu··on OpenAI declares 'code red' as Google catches up in AI race
I think Theano takes the crown as first modern end-user library for autodiff and tensor operations.
ckrapu··on Show IH: My App for Retail Investors
Mobile experience is not great
ckrapu··on I no longer engage with Nature publishing group
I agree with some of the author’s criticisms, but diversity citations are a minor concern compared to the idea of paid access to publicly funded research.
ckrapu··on Ideas on how to improve my teaching repo?
I want to help teach basic application design for GenAI. I've got a basic repo setup, but it's largely based on my own developer experience.

Any feedback is super appreciated.

I'm aiming it at new college grads who haven't had to maintain several services at once in production.

ckrapu··on How Hyper Built a 1m-Accurate Indoor GPS
Do you think the basic physics and sensor tolerances would let you go to 10^-2 meters if the environment (e.g. wifi station placements, location of RF-interfering elements) was designed by you?
ckrapu··on Degrees are merely the receipts for the money you spent
The title is true if there is no meaningful selection or attrition process for your degree. Otherwise, I disagree strongly.

I think that one’s opinion of this article’s premise is really an index into what your program was like.

ckrapu··on Show HN: Invest in Trends Instead of Individual Stocks
Nice idea. The AI infra trend was pretty bad, though. Where are coreweave, nebius, supermicro and others like them? The selection of companies seems like it came from an LLM without any knowledge of the last two years.
ckrapu··on Shrinkle – Shrink words, find hidden phrase
I love the idea but when I tried to reduce "SCARFS" to "CAR" (the right answer) it rejected my choice of S, but let me select the other letters. Looks like a bug. Clean it up and I would love to play more!
ckrapu··on Be thoughtful when retiring old domain names
This happened to me when I decommissioned an App Service instance on Azure.

I totally forgot that it has a readable (I.e. guessable domain name) because AWS’ equivalent service doesn’t. I also had a company subdomain pointing to it so someone got to put up a malicious page on our domain for a day :(

ckrapu··on I am a SOTA 0-shot classifier of your slop
I do know my writing style has problems. My writing teacher said my style was pretentious, and I try to tone it down.

I sort of take this as a compliment, because I've been writing like this my whole life and if it reads like LLM slop, then there's the implication that the result of all of OpenAI's A/B testing and post-training leads to something like my style which at least means it gets people to engage with it!

ckrapu··on I am a SOTA 0-shot classifier of your slop
My colleagues definitely thought it was a joke at the time.

We had this project (all public research) to classify buildings and identify their different subsystems (e.g. load-bearing structure, roof type, ventilation type) to figure out the expected casualties if there was a WMD event of some type. We could get decent data for much of the world, but for some places we had literally nothing beyond a tiny picture of it from satellite imagery.

I had been playing with using GPT-3 to try to have it autocomplete forms like the following. This was 2021 before we had good APIs for instruct models, so this was just straight up letting the LLM regurgitate after pretraining. Here was the type of prompt we used:

""" Engineering building report for building located at 123, X Street, Knoxville TN Prepared by Benjamin Lee, FE --- Building footprint area: 1200 m2 Roof type: built-up roofing Facade material: brick HVAC present: """

Surprisingly (at the time), this was a decent prior. You could also add all sorts of one-off points of interest and amenities like swimming pools and other trivia to help guide the conditional probabilities.

I did make a comment to that effect at the end
ckrapu··on I am a SOTA 0-shot classifier of your slop
Do it, but just don’t pass it forward blindly!
ckrapu··on I am a SOTA 0-shot classifier of your slop
To be honest, as the author, I am pretty insecure. That sounds like an accurate reading.
ckrapu··on I am a SOTA 0-shot classifier of your slop
Admittedly cringe, and changed!
ckrapu··on Top Employers of CPT Visas: Amazon, Tesla, and Lindsey Wilson University? [pdf]
What is going on here? Is there some sort of game being played with the CPT system?
ckrapu··on Show HN: I wrote a "web OS" based on the Apple Lisa's UI, with 1-bit graphics
Very cool.
ckrapu··on The Genius of Scar Tissue
Reads like it was written by ChatGPT.

By this logic, I lost $500B by not getting options on NVIDIA and timing every single successful jump.

Looks like it was mostly LLM generated

Makes perfect sense. Looking forward to trying this.
