Formerly at kCura/Relativity, security. I do application penetration testing for hire these days. Happy to chat about application security, programming, and ham radio. My conversations about agriculture are not that interesting.

Security: https://ciexinc.com/ Of particular interest are the solarwinds articles at https://ciexinc.com/blog/solarwinds/index.html Old very fun projects: https://ciex-software.com

“Eventually, all things merge into one, and a river runs through it. The river was cut by the world's great flood and runs over rocks from the basement of time. On some of the rocks are timeless raindrops. Under the rocks are the words, and some of the words are theirs.

I am haunted by waters.”

Beware the anxiety industrial complex.

That is approximately 513 comments each hour or 8.55 each minute.

Not humanly possible for two moderators to view and make judgement on even a small fraction of these comments.

Let's not post down announcements. They are not interesting in the sense of HN.
wglb··on 8087 Emulation on 8086 Systems
While I was at Mark Williams back in the day, the engineers wrote 8087 emulation floating point for the Mark Williams 8086 compiler. This involved some quality time with the Volume 2 of Knuth in the log division section.

I submitted and had to edit the title for length—no other changes.

wglb··on Want to write a compiler? Just read these two papers (2008)
> It seems to me LL and LR parser generators are overrated, and hand-written recursive descent is best in practice

I would now agree with that. My compiler experience was on a team that happened to have a LALR expert, Jeanne Musinski PhD, a student of Jeffrey Ullman. She invented a better error recovery for the language. Recursive descent would have been perfectly suited to the task.

> LR being more expressive than LL has never mattered.

Quite agree. One might guess that a language that needs that might be hard to program in.

wglb··on Want to Write a Compiler? Just Read These Two Papers (2008)
A significant fraction of my technical library is used just this way--as a reference, checking out the parts to answer a specific question.
wglb··on Want to write a compiler? Just read these two papers (2008)
When I was professionally writing a compiler professionally (see https://ciex-software.com/intro-to-compilers.html) the Dragon book was the second book that I read. I found it very helpful. That was the first Dragon book. I got the second one later. I would have been ok to start with the Dragon book--the Compiler Generator book was a harder study.

This is why these postings are not interesting or useful.
wglb··on The threat is comfortable drift toward not understanding what you're doing
No problem with that.

However, at one point in my career, I was frustrated with limitations in a language (Fortran II) and my curiosity got the better of me and I studied compilers thoroughly.

This led to a new job and the understanding of many new useful programming concepts. Very rewarding.

But if you are curious, studying compilers, maybe even writing a new one, will give you tools to do other things.

While working with LLMs, much of my experience gives me new ideas to push the LLM to explore.

wglb··on Ask HN: Anyone else struggle with how to learn coding in the AI era?
I've been programming for 60 years. I started working with LLM in mid-2025 and have created a number of useful tools in my consulting business. For the programming part, and actually the planning part, I estimate that it increases my productivity by a factor of 5.

Additionally, I always am looking closely at the code and I think I am an incrementally better programmer.
