pentaphobe··on Show HN: I recreated 90s Mode X demoscene effects in JavaScript and Canvas
Neat! The nostalgia is palpable.

Off topic: we always referred to mode-x variants as MCGA, TIL that's more of a colloquial term than a technically accurate one [1]

That's a great approach - definitely adding your framing to the toolbelt, thanks for that!

kind of organically landed on a similar thing, where initial task is kept pretty simple (but not covered by common libs)

Some folk solve and code this quickly, so we add a requirement. (Generally up to a few stages - think like Advent Of Code)

Any leftover time can be spent discussion wishlist items for productionising, optimising, tests, etc..

But: plenty of people only complete the first stage, but this can absolutely be a pass too (based on comms style, approach, etc..)

Ooh thanks, totally missed this!

"... write their own reverse.."

Yeah spot on - exactly what I was aiming at too...

Having the intuition to use reverse (& pragmatism to keep it simple) is a great sign, and realistically more valuable [to me] for hiring than implementing rudimentary algorithms, but... still want at least a bit of both abilities

Also knowledge of standard library / language features is useful but (for me) doesn't equate to abilities in complex problem solving.

But honestly could be bias :)

IANAP so got curious about how ZX Calculus related to Feynman Diagrams (if at all)

Search landed on this neat summary [^1] (2024) from the lab(?) which also has a link to the original paper [^2]

Always fun to see this kind of Rosetta Code thing, feel like no matter the topic there's something to glean from reading!

That said: if I ever gave the palindrome question to a candidate (I haven't) and they pulled out a `reverse` library func/keyword we'd be encouraging them to do more.

pentaphobe··on Working on complex systems: What I learned working at Google
Let's add a post post scriptum :)

Just because your project might not be at Google's scale doesn't mean it is therefore also not complex [^1]

Example: I'd say plenty of games fit the author's definition of "complex systems". Even the well-engineered ones (and even some which could fit on a floppy disc)

So yeah, seems like despite some unfortunate liquidation choices by his parents just before the depression, they still retained enough wealth to make certain lifestyle choices easy...

> His parents, upon his graduation, had decided to give him a monthly allowance of $200 out of their earnings from Cobblestone Gardens, a substantial sum in those days.

> It was enough to keep him going, and indeed it guaranteed his survival for the next twenty-five years, arriving with welcome regularity. The allowance was a ticket to freedom; it allowed him to live where he wanted to and to forgo employment. [1^]

And $200 in 1937 gets you a fair bit of freedom (roughly $4500 in today's money) - sure, it's not private jet money but notable. And would have gone pretty far in Mexico and Tangier.

Oh neat! Had no idea about this - thanks for the share
pentaphobe··on Back From The Future: 1995's predictions of 2025 life
Ah, just saw that the author has included the original text as PDF so don't have to speculate about original intent after all

Does seem to mostly be "here are some people in touch with current developments happening in the world thinking about their next phase" more than full-blown futurism - but still super interesting to read (if only to see the vestiges of tech optimism pre-dotcom-enshittification)

A few things which leap out that weren't included in the original post:

- "everything will be smart - that is, responsive to its external or internal environment"

Predicted the glassy eyed dream at the time, but not the more cynical reality we got where that smartness more often benefits the seller than the consumer

---

- "in-depth personal medical histories will be on record and in full control of the individual in some form of medical smart card or disk"

Another fun combo of rarely safe prediction based on developments of the time mixed with (in hindsight) overly optimistic assumptions about commercialism

---

And the bit summarised as purportedly predicting "(the internet)" actually has a pretty neat bit which was missed

"face-to-face, voice-to-voice, person-to-data, and data-to-data communication will be available to any place at any time from anywhere."

Predicting Skype/zoom seems a tad more interesting (even though things like Dick Tracy or 2001: A space odyssey had long had us wishing for it before 1995)

The preceding bit aged less well

"...broadband network of networks based on fiber optics; other techniques, such as communications satellites, cellular, and microwave will be ancillary."

Interesting that they appeared to be emphasising an _increase_ in wired data transit

But not surprising, as back then any cellular comms were far from impressive in comparison to the big-ass wired links you could use from universities

(That said, even back then we had microwave links acting as secondary high speed links for campuses which didn't yet have fibre or coax installed)

pentaphobe··on Back From The Future: 1995's predictions of 2025 life
Seems like the author kind of missed (or buried) the point when summarising the "global fibre-based broadband network" prediction as simply "(the internet)"..

I was using the internet in 1995 - and pretty sure at least part of that connection use was over fibre, so I don't imagine someone trying to get away with predicting that.

But the path to my house was still a phone line - so I assume the original prediction was more about that fibre eventually running to our houses - certainly something many of us were looking forward to back then particularly any time someone in the house picked up a phone and killed our connection :)

(EDIT: have added an amendment in reply to this comment after reading some of the original PDF)

As for high contrast digital paper, that was also already part of the collective wishlist

Neal Stephenson's The Diamond Age [1] came out in 1995 and featured an e-book with an embedded AI and nanotech based display surface

BUT e-ink was first investigated at Xerox PARC in the 70's and was already under development by 1995 at MIT's media lab (commercialised in 1997 but hardly as bug a leap as it sounds) [^2]

(Posting as separate comment because wall of text)

Also - Honestly don't even understand why so many people would need to scrape for training data.

Is it naïveté (thinking it necessary), arrogance (thinking it better than others, and thus justified)?

Aren't most advances now primarily focused on either higher level (agents, layered retrieval) or lower level (eg. alternatives to transformers, etc.. which would be easier to prove useful on existing datasets)?

Genuine questions, all of these - if I'm off the mark I'm keen to learn!

pentaphobe··on Please stop externalizing your costs directly into my face
Is there currently any way to identify ethical (or I guess, semi-ethical or even not actively unethical..) AI companies?

Would be nice to see some effort on this front, a la "we don't scrape", or "we use this reputable dataset which scrapes while respecting robots.txt and reasonable caching", or heaven forbid "we train only on a dataset based on public domain content"

Even if it was an empty promise (or goodwill ultimately broken) it'd be _something_. If it exists, I'd certainly prioritise any products which proclaimed it

Do we need to make one?

Not quite what you're asking for, but if your device's browser doesn't have a "reader mode" there are sites like this one which can help:

https://clearthis.page/?u=http://fweet.org/

(Not affiliated with either site, and haven't done due diligence on clearthis - was just first site I found which appeared to behave as expected)

His "little" essay in Coincidance really opened my eyes to the depth of this book

Still haven't personally dug through Joyce's notes (as RAW clearly did) but just getting to see the book through eyes that have was mind blowing in my 20's

Excellent! No idea how this hasn't shown up on my radar before

Many thanks, kind stranger

pentaphobe··on Show HN: Handwritten Cards – Send Cards Online in Your Own Unlegible Handwriting
Love the idea (and the headline gave me a chuckle)

Might be worth including a privacy statement about the handling of people's handwriting (meta)data, ie. disposal, not selling or using it as training data (assuming that's the case of course!)

No idea how many people would care, but was the first thing I looked for (habit before I share new things with non-techy friends)

pentaphobe··on I shouldn't of made this. Another direnv alternative for no reason
As an aside: despite caring about "correct" use of language I've always been willing to frivolously split infinitives - it's against the rules, but I think quite an effective evolution of language

Good to have linguists around reminding us to boldly go explore :)

pentaphobe··on I shouldn't of made this. Another direnv alternative for no reason
Glad you made this - whether it needs to exist or not seems far from relevant as reworking and rethinking things is why we have most of the coolest tools we take for granted :)

Did you discover anything interesting in the process of building it?

pentaphobe··on I shouldn't of made this. Another direnv alternative for no reason
As a (barely) recovery grammar festidian I highly recommend checking out this video by Dr Geoff Lindsey [1]

TLDW: some fascinating realignment of perspective from a linguist about such things [^2], and the - frankly moderately mind-blowing - revelation that despite caring about language I've been gleefully pronouncing "covert" 'wrong' my whole life (and will likely continue to do so)

Sucks that you're getting downvoted - it's an interesting point that the headline appears to blame an inanimate object
