armitron··on Common Lisp implementation of the Forth 2012 Standard
Not to mention more perfomant than Lispworks.
armitron··on California police aren't loving their Tesla cop cars
One wonders what the point of this article is besides “we fucked up by choosing something that we should have known did not fit the constraints we had”.
armitron··on Chrome Canary just killed uBlock Origin and other Manifest V2 extensions
Isn't Chromium open source? How hard would it be to fork and restore Manifest V2? I'd expect the functionality to be fairly isolated so that easily tracking upstream becomes manageable.
armitron··on Boris Vallejo and the pixel art of the demoscene
Compare Vallejo to Frank Frazetta and it's immediately obvious why the latter is considered a master of fantastic art while the former is drifting towards obscurity.

Frazetta's art is full of tension [1] and energy [2] whilst Vallejo is simply drawing his circle of bodybuilders in various poses. The environments he paints have absolutely no effect on his posed subjects and the end-result is disconnected and comes across as "fake" in its intended setting as it evokes memories of bodybuilding gyms.

armitron··on Alan Kay on Messaging (1998)
Top down architecture doesn’t scale and puts a hard limit on the problems one can tackle before complexity explodes. The Internet, the largest distributed system we have, is based on bottom-up cell-like biologically inspired models. Kay was prescient and decades ahead of his time.
armitron··on Rewriting Rust
Our main languages are Go and OCaml. We can leverage third party libraries without easily running into transitive dependency hell as there’s an implicit understanding in these communities that large number of dependencies is not a good thing. Or, expressed differently, there is coarser granularity in what ends up being a library. This is not the case with Cargo which has decided to follow the NPM approach.
armitron··on Rewriting Rust
This is the main reason we have banned Rust across my Org. Every third party library needs to be audited before being introduced as a vendored dependency which is not easy to do with the bloated dependency chains that Cargo promotes.
armitron··on Optimizing Guile Scheme
It's still much much slower than SBCL which is not surprising given the time & effort that went into the latter. User-guided optimizations (type declarations, stack allocation, intrinsics, machine code generation) in SBCL are also more flexible and better integrated.
armitron··on Omni, the Iconic Sci-Fi Magazine, Digitized in High-Resolution (2017)
The high resolution digitized versions are no longer available for purchase at Amazon, just a single issue June 1987. They're also not available anywhere else that I know of, the archive.org versions are inferior / bad scans / low resolution.
armitron··on fd - A simple, fast and user-friendly alternative to 'find'
This and other newcomers (e.g. exa, ripgrep, ..) are not specified by POSIX and thus not ubiquitous. For someone that interacts with multiple UNIX systems daily, I find that the tedium of maintaining -sometimes multiple versions- and moving these binaries around is greater than the benefits they provide.

The same can be said for new shells that have popped up in the last 5-10 years versus bash. They're not sufficient to escape the local minima of 'good enough'.

armitron··on US health system ranks last compared with peer nations – report
Are you living in the UK or just making baseless assumptions? For an ever-inceasing number of serious health issues, the NHS has been essentially non-functional for many years. I have friends with chronic conditions that are looking to emigrate becase they're dreading their health getting worse in a system that's doing nothing to help them.

"NHS would be great except for the bad politicians" is not a serious argument.

armitron··on US health system ranks last compared with peer nations – report
The only explanation is that the "report" is obviously detached from reality and using massaged metrics to make political points. The NHS is as bad as it gets.

"More than 120,000 people in England died last year while on the NHS waiting list for hospital treatment, figures obtained by Labour appear to show. That would be a record high number of such deaths, and is double the 60,000 patients who died in 2017/18."

armitron··on Is God a Strange Loop?
> I disagree with Hofstadter that consciousness and free will are illusions. But I wholeheartedly agree with his most original, profound claim: at the bottom of everything, something is doing something to itself.

This is a ridiculous claim, on the order of quantum woo. He disagrees with a cascade of data from neuroscience because it doesn't fit his preconceived notions about "god" and "consciousness" and chooses to believe in mystical unfalsifiable bullshit. Amazing what passes for "science writing" these days.

armitron··on Business Moleskine Mania: How a Notebook Conquered the Digital Era
The web is full of independent observations of that exact fact, here's one that even comes with photos [1] but don't let me shatter your illusion. Feel free to keep giving them your money and supporting the enshittification.

"Are Moleskines fountain pen friendly? No. The paper quality is low in general, and fountain pen users will experience ghosting and bleedthrough that prevent you using both sides of the paper, and even some feathering on the front side. There are far better options available, and at a cheaper price."

armitron··on Business Moleskine Mania: How a Notebook Conquered the Digital Era
A moleskine is an overpriced crap notebook at this point. Paper quality has drastically diminished from what it used to be, to the point where one can't use fountain or gel pens without bleed through. Another example of enshittification.
armitron··on Bugs, mold, mildew found in Boar's Head plant linked to deadly listeria outbreak
Never tried it or even seen it in supermarkets in Texas. I will if I get the chance.
armitron··on Bugs, mold, mildew found in Boar's Head plant linked to deadly listeria outbreak
Only "deli" meats I will eat are PDO Prosciutto di Parma imported from Italy and less frequently PDO acorn-fed Jamón ibérico imported from Spain.

Pretty much everything else sold at US supermarkets is filled with nitrites, even when packaging insists that's not the case it's usually celery powder sleight of hand, and generally horrible for one's health.

armitron··on The tragedy of low-level exploitation
Mark Dowd's 2023 presentation "Inside The Zero Day Market" [0] is extremely informative and a must read for everyone interested in a low-level exploitation career.

armitron··on The 1-HR nurse visits that cost $15B to Medicare
Having lived in a number of European countries with single payer systems some of which are in a state of collapse, that's not even remotely true. I would characterize the level of care I receive in the US (fully paid by my employer) as absolutely top notch.
armitron··on C Isn't a Programming Language Anymore (2022)
For someone who's been writing "C for 20+ years" according to your other post, you come across as extremely ignorant of how modern optimizing C compilers work. I suggest you thoroughly read and understand Russ Cox's simple expose [1] and the UB posts in John Regeh'r blog [2].

The C security issues that plague us today are partly fueled by the attitude of guesswork and ignorance demonstrated in your posts.

armitron··on The Academic Culture of Fraud
I'm afraid it's not simply a matter of wasted money but one of profound institutional rot that drives away large numbers of the best and brightest. The article outlines this by focusing on the proto-scientist archetype and the spiritual, uncompromising pursuit of Truth. Today's academic culture is for the most part completely antithetical to a person possessing these attributes.

That some can endure the suffering and keep working in this sort of environment does not reflect well on today's institutions and doesn't inspire much optimism for the future of academia.

armitron··on Reverse Engineering for Everyone
I found so many mistakes, badly understood concepts and entirely wrong explanations just reading for 5 minutes, that I can't possibly recommend this. It's obviously written by amateurs / people with minimal experience of the domain.

Much better resources are Eldad Eilam's "Secrets of Reverse Engineering", for Windows "Practical Reverse Engineering" and for the absolute basics, Patterson's "Computer Organization and Design".

armitron··on Self-Awareness Might Not Have Evolved to Benefit the Self After All
It's absurd to believe that consciousness is in any way responsible for decision making. There's no plausible scientific model that would allow for that to take place without breaking causality. Instead, we have strong evidence that points to consciousness being an epiphenomenon of brain activity, completely detached from action.
armitron··on Reasoning skills of large language models are often overestimated
The "GPT-4 Can't Reason" paper [1] [2] is excellent and proves without a shadow of a doubt that there is no reasoning taking place. It also raises strong doubts about the efficacy and reliability of multi-agent approaches that rely on LLM-based planning (such as Cradle [3], which is currently on the front page).

When it was previously discussed here, it received a torrent of low-quality comments that can only be described as confirmation bias: commenters tried the examples verbatim (instead of introducing random perturbations to get around model updates) in order to disprove the thesis.

It's sad that there are "engineers" out there so blinded by their own (wishful thinking, vested interests) that can not accept the obvious.

armitron··on The Origin of Ambergris (2012)
It's Kouros with no aldehydes, less sage, no coriander/cinammon/leather, retaining the civet but a bit different: the pissy notes are now even sharper but the "fecal" notes are gone, more citrus/fruit (some say pineapple but I can't pick that up) and a similar legendary warm/soapy/amber drydown, what you'd expect an ancient Greek temple full of burning incense to smell like.

It's definitely in the same league as Kouros, and much more wearable in the summer.

Kouros Sport (which I also have) is not as good, as it doesn't project as much and all the notes are greatly diminished as if they've been diluted.

armitron··on The Origin of Ambergris (2012)
It's not ambergris that gives Kouros its characteristic pissy notes, but civet (also real oakmoss and strong aldehydes) ingredients all of which they toned down in the early 2000s and then completely removed in 2008 (Loreal era).

The Kouros you can buy these days (white instead of metallic shoulders), is heavy on coriander with barely any "musk" and bears little resemblance to the "scent of the gods" of the 80s and 90s. I still have multiple bottles from the 90s which are as good as ever, together with Kouros Fraicheur from the same era which is another Pierre Bourdon masterpiece. YSL perfumes from the 80s and 90s were legendary.

armitron··on Gerald Sussman: Programming is (should be) fun (2022) [video]
> Margaret Hamilton worked out how to write bug-free software during the Apollo 11 project. The IT industry collectively went, "meh."

That's an often repeated myth but it collapses the moment one digs a bit further (rather than swallowing preposterous statements). She was a glorified manager at best, others did the programming that actually mattered.

Hal Laning [2] was primarily responsible for what Hamilton gets credit for.

armitron··on Gerald Sussman: Programming is (should be) fun (2022) [video]
That's not accurate. They retired SICP and added a new introductory course [1] based on Python to placate the suits. Neither Sussman nor any of the other SICP folk is involved with that.

Sussman created a follow-up course to SICP [2] which is still based on Lisp and still being offered today.

armitron··on Lynn Conway has died
Idiosyncratic with a genius-level 155 IQ (which is something that the prevailing cultural zeitgeist does its best to bulldoze)
armitron··on Ask HN: 30y After 'On Lisp', PAIP etc., Is Lisp Still "Beating the Averages"?
Lisp is not for everyone and based on what you wrote, it seems to me that it's clearly not for you. So I would suggest you stop wasting your time with a language that's obviously not a good fit.
