jojohohanon··on Eating the Birds of America: Audubon's Culinary Reviews of America's Birds
I think Roald Dahl had one story about a man who went to great lengths to eat a ghost.
jojohohanon··on Connection Machine Lisp (1986)
Are you referencing strictness analysis?
jojohohanon··on Just Enough Software Architecture (2010)
I am very interested in learning more / honing my design skills,

But

Like everyone else my time is extremely limited. Could you say a few words about DDD stood out for you and what other books you might compare it to?

jojohohanon··on Ask HN: Seeking ideas for preschool/school projects
My 1st grader loooves tape. And dolls. And we order Amazon regularly. We have purchased one of the simple cardboard knives.

The simple level is to turn the Amazon boxes into doll houses.

Slightly more advanced is to make furniture for the dolls. Like a simple shoebox quickly becomes a Barbie closet.

For bigger boxes, given the right shape, it is easly to cut and fold a high hair.

jojohohanon··on PeaZip: Open-source file compression and encryption software
It blends the CLI by incorporating scripting engine?! That’s not what mean by cli friendly.
jojohohanon··on Show HN: A web debugger an ex-Cloudflare team has been working on for 4 years
oooh. you got them. Like figuring out which timezone the user was in is impossible. What if the user intentionally set their clock wrong to mess with support.

You are being silly.

jojohohanon··on Scientists find optimal space-time balance for hash tables
Spacebar is next page is old-as-ages terminal convention.

But it has no place in a browser.

jojohohanon··on Grabby Aliens (2021)
Why are we now?

https://www.ox.ac.uk/news/science-blog/why-are-we-now

It’s early here, but it think the gist of it is using Bayes to quantify:

Given that the universe would seem to get more hospitable at older ages,

why are we alive now?

IIUC the most likely explanation is some secondary force (aliens) to modify the future hospitality.

jojohohanon··on Ask HN: Who wants to be hired? (January 2024)
pitch: Simple designs and solutions for complex problems

Location: Greater Boston / Remote Remote: yes. prefer hybrid Willing to relocate: no Technologies: backend. java python go aws postgres mongo django flask springboot. lisp. padis / edifact. Résumé/CV: short links here: https://bit.ly/jeo_linkedin Email: short links here: https://bit.ly/jeo_linkedin

prefer a local office with hybrid attendance so I can meet cow orkers face to face. No ads. No gambling. No cars.

jojohohanon··on Benjamín Labatut Will Not Be Profiled
How do you feel about borges?
jojohohanon··on Merkle Town: Explore the certificate transparency ecosystem
I assume the name is a reference to merkle hash trees, but I don’t really see the connection.

Can someone spell it out?

jojohohanon··on How the append-only btree works (2010)
I think the insight here is that garbage is garbage and the generational hypothesis holds for DB trees as well.

So if we track and treat young nodes specially, we can then promote a subset of them into the permanent tree and dispose of the rest. Per the hypothesis, nodes in the permanent tree will also die, but at a lower rate.

jojohohanon··on Dissolves: The out-of-fashion film trick that makes 'The Holdovers' so affecting
“Out of fashion” aka “The heavy hand of George Lucas can ruin most every thing”

Imho

jojohohanon··on Victor Mono Typeface
Obl: everytime we do a font thread, I ask if anyone knows a font that is

* proportional

* sans

* has programming ligatures

* clearly differentiates 1l and 0O

The closest I’ve come was iosevka. But it was not quite proportional and I wasn’t font of its looks.

jojohohanon··on LMAX Disruptor – High Performance Inter-Thread Messaging Library
I came across this a few years back when numbly watching the dependencies scroll by during some Java install.

“Disruptor is a fairly presumptuous name for a package” I thought. So I looked into it. It fed musings and thought experiments for many walks to and from the T. I love the balance between simplicity and subtlety in the design.

If i recall, it was a dependency for log4j, which makes sense for high volume logging.

jojohohanon··on Orthodox Privilege (2020)
There was a website aimed at something similar called “the factual” but they never really got the algorithm off the ground before they were bought - by yahoo news by all things.
jojohohanon··on Orthodox Privilege (2020)
Thanks for this. It was a blind spot I didn’t realize I had.
jojohohanon··on AngleLock, improvement on T-slot aluminum framing system (2022)
It seems that you could add mechanical rigidity and remove the freedom of rotation by adding washers into the mix: washers that have small extrusions to for into the slots next to the bolt. Parallel, perpendicular, or at dome fixed angle.

But I imagine these aren’t needed since everyone who builds with nails or t slots realizes the rotation must be countered not in the joint, but in external bracing. (Aka triangles)

jojohohanon··on Clearview AI: secretive company that might end privacy as we know it (2020)
I want someone to make the ugly shirt.
jojohohanon··on Chez Scheme: Lisp with native code speed
No I’m referencing the fact that both had pretty strong teams overlapping in Northeastern University.
jojohohanon··on HP fails to derail claims that it bricks scanners on printers when ink runs low
I swear by the lowest end brother duplexing monochrome laser printer. Mine is the dw2270 which was <$150 at the time. Rock solid. No fuss ever.

I’ve praised it here before. It’s the sort of printer that I wonder they stay in business selling because each customer is a customer for life but only buys one item.

jojohohanon··on Chez Scheme: Lisp with native code speed
I always assumed racket was built on twobit/larceny.

jojohohanon··on Four Lectures on Standard ML (1989) [pdf]
I never could wrap my head around the context variables or whatever they were called, where the language would pick a random variable from your local environment and pass that as an argument to the function call.
jojohohanon··on Why don't we get our drinking water by taking salt out seawater? (2008)
Not the full column.

You pump out the top x feet of water from the pipe. The equalizing levels of inside and outside the pipe is what drives the upward flow through the membrane.

jojohohanon··on Google no longer automatically indexes websites?
Checking if site connection is secure

And I left. Irony all exhausted

jojohohanon··on The 2-MAXSAT Problem Can Be Solved in Polynomial Time
The first step is to encode some decent password cracking challenge into an NP complete problem - choose 3 SAT or something similarly well understood. Then encode that 3sat problem into the paper’s solution domain.

If you get a password in polynomial time you are golden.

jojohohanon··on Best printer 2023: just buy this Brother laser printer everyone has, it’s fine
What really steams my clams are sites that wholesale lift reams of copy, minus introduction and summary, from Baeldung and others that do the good work, but pepper them with enough google bait so that they are ranked higher than the original. (I speculate that detecting and down-ranking this practice is not considered a priority by google because the copy-cats are riddled with ads so generate more revenue per organic result listing)

I find this collusion unethical. And should be illegal, but I hesitate to ask our lawmakers to understand the nuance when their lobby income stream relies on the opposite.

jojohohanon··on Best printer 2023: just buy this Brother laser printer everyone has, it’s fine
You never run out of toner in a cartridge. Just give it a shake for another lease on life. It’s like Zeno’s paradox. You just have to shake it increasingly often.
jojohohanon··on Python-based compiler achieves orders-of-magnitude speedups
Isn’t it “self”, really? [1]

Assume your python program is fully static and well behaved from a compiler perspective. JIT compile it, and observe what it does, so that you can invalidate the compiled code and re-JIT it if it does something overly dynamic.

Incidentally, what JVM did. (I’m sure now it’s been tweaked beyond recognition)
