RetroTechie··on 'Likweli': A new monkey species discovered in the Congo Basin
> Dear monkey, please run, and run far!

Where to? Article says they're in a national park already (and even there, hunted sometimes).

RetroTechie··on I Owe My Life to the Commodore 64
> If I had to pick, my nostalgia lies with Windows 95 to 98.

Ouch.. I truly feel sorry for people who've never had the experience of "switch machine on, wait 1..2 seconds, start coding". All the machine's capabilities at your fingertips. No OS install to maintain, no updates, no viruses, no hassle.

It was sooo easy to get into (not to master!). Stores in my country would have a C64, ZX Spectrum or MSX running a demo or something, you'd come in, hit a key combo, type something like:

  10 PRINT "RetroTechie was here    ";
  20 GOTO 10
And the store's machine would show your name scrolling until the next kid came along. Color, sound, games & machine code were next.

For example an early machine code adventure: I'd read in a magazine some biggest prime number had been found. Fyi: a Mersenne prime, 2^n-1, with n being a big number (10k+).

I quickly realized that number could fit into ZX Spectrum's 48K RAM, if encoded 2 decimals/byte (packed BCD or plain binary 0-99). Worked out Z80 assembly code to do 1 doubling using pen & paper. Some POKEs, a small BASIC program, and voila some semi-big primes appeared. Upped the counter, machine was number crunching for hours, and... yes! Starting & ending digits matched those in article. All the digits from biggest prime science had found up till then, calculated by that humble machine.

Just one of many examples. Modern computers are many orders of magnitude more powerful. But imho much of that era's magic was lost. Windows 95/98 you say? Booorring...

RetroTechie··on I Owe My Life to the Commodore 64
"Luft" in German = "air".

So English title would be "99 air balloons" or just "99 balloons".

(Excellent choice btw, among German-language songs it's an all-time classic)

RetroTechie··on Minikotlin
Also, it's only "by hand" if you, the developer, writes it. In this case:

"The frontend — lexer, parser, semantic analysis (it’s called mkf) — hands off to two of its own IRs before writing WASM-GC by hand."

So those frontend tools do the writing, not the developer?

That's not "by hand". One might say "writes WASM-GC directly". But no that also doesn't happen, it goes through an IR first?

Personally I wouldn't put too much trust in a developer that even can't get their terminology correct. Well either that or I foobar'd my understanding of the writeup?

Anyway, looks like an interesting project.

RetroTechie··on Multi-Primary Color Display Emerges as Next-Gen Color Reproduction Technology
If you're using 4 of them versus 3, wouldn't this require 1/3 more subpixels to achieve the same display resolution in pixels?

Or -using same # of subpixels per cm^2- would perceived display quality be similar due to better color representation?

RetroTechie··on Solod: Go can be a better C
Wikipedia says Alef lacked garbage collection, contributing to it being abandoned.

But does Limbo have any 'fatal flaws' like that? Especially compared to Go.

No doubt Rob Pike is a prolific and capable programmer. But seems like he needed quite a few attempts before arriving at Go (looking at C's flaws -> Alef -> Limbo -> Go, Wikipedia also mentions a domain-specific language called Sawzall).

RetroTechie··on Photos of items from families in different countries with different incomes
What's missing in comments:

In developed countries, people buy (or rent) the things they need. Most financial transactions are recorded, taxed, regulated, and with 3rd parties involved at every step (who also expect to get payed). Car insurance, home insurance, electrical bill, etc etc. Grocery prices go up, you pay more. Renting, and rents are raised? Tough.

But in less-developed countries it's not rare for people to grow their own food. They could be living on 0 income & still have food on the table. Swap produce & services with other people in town. No 3rd parties, no taxes (see: informal economy). Build their own home on family-owned land. Insurance? What insurance?

TLDR; there's many flavours & angles on what "poor" or "rich" means in practice.

RetroTechie··on Sony deletes more movies from the accounts of people who ‘bought’ them
> Curious what others use to store media for home/remote use.

A limited selection of CD/DVD/BluRay, a large collection of songs in mp3 & other formats (many ripped from CD myself @ some point, others downloaded), a bunch of movies in h264/h265 etc (mostly via torrents).

Books / documentation / retrogames & more on various devices.

Generally when adding anything, I look for replay value. Play/watch/listen once & never revisit stuff I save to /dev/null.

In common between all the above: storage media under my control, and useable offline.

RetroTechie··on British Steel taken into public ownership to protect 'vital' UK supply
It's not boutique vs large plant. It's base materials (paper mills, steel smelters, plastic etc) that tend to be low in added value, versus higher up the stack (like your examples) that also tend to be higher in added value.

Most countries didn't care much for the former other than historic reasons, but like the latter for obvious reasons (add £ to GDP).

That's changing due to "sovereignty". You can't build a satellite without metal profiles, wiring, tubes etc. Which requires manufacturing capacity for those. Which requires steel/alu/copper smelters & plastic extruders. Which requires plastic & thus a chemical industry.

This whole 'sovereign movement' is about keeping/bringing back capabilities across the stack which are deemed critical (like steel).

But I suspect there are few (if any) countries that have these dependency chains mapped out in detail.

RetroTechie··on Umuganda
Better if it targets a wider scope (eg. community-building) than just cleanup.
RetroTechie··on Where are YC founders now? OpenAI and Anthropic, mostly
It's a set of properties/attributes commonly referred to as "style" (generic, not the CSS one). Or call it look & feel.

So you're saying the site screams "Claude's style!" to you. Not too different from "I know a WordPress site when I see one".

RetroTechie··on At least 105 past YC founders have worked at OpenAI and Anthropic
What part of "start a company" requires "grinding 80h weeks"?

Sounds to me as inability to delegate. Or implicit in the [acquire VC, aim for high growth] mindset as if that were the only path to success.

Companies can grow organically. With a positive cash-flow early on & reasonable work/life balance for founders & employees alike. Heck, there's even non-profits.

RetroTechie··on The 3-degree limit could be exceeded as early as 2050
> The population problem was solved by some chemical reaction using fossil fuels to create fertiliser so crop yields could increase

"Solved"? It helped us become dependent on fossil fuels for food. And more mouths to feed.

> What’s going to be the tech solution this time?

There might not be one this time. And/or the core problem(s) are not technological.

RetroTechie··on The 3-degree limit could be exceeded as early as 2050
True, high-tech supply & manufacturing chains are hard to mantain if social structures break down (as is happening already).

But you'll probably see large-scale crop failure first. It's simply not possible to grow the world's food supply indoors.

Migrant flows, political chaos & wars can do the rest.

Imho it's too strong to say that will happen worldwide. But on local (country/regional) scales? Absolutely.

RetroTechie··on Hack Reveals Suno AI Music Generator Scraped YouTube, Deezer, and Genius
Must be some Terms-of-Services on the websites mentioned, that forbid this kind of thing, right?

It's not like the company hired 1000s of workers (each individually agreeing to YT's ToS) and have them dial model weights up & down.

RetroTechie··on Mawlynnong, India, transformed by tourism, bans visitors on Sundays
Netherlands back in the day had signs saying:

"Laat niet, als dank voor het aangenaam verpoozen, den eigenaar van 't bosch de schillen en de doozen"

(old-ish Dutch spelling. From ~1930). Translated:

"Leave not as thanks for your pleasant stay, the owner of the forest the peels and the boxes". (google for pix, they're nice!)

Today, I'd be a happy camper if it were just peels & cardboard since both bio-degrade. Unlike most other litter (smoking-related and balloons among my 'favourites').

But it's definitely a cultural thing. Learn kids @ a young age, problem goes away.

RetroTechie··on Pseudpocalypse
> So anonymity of written speech is toast.

No just use a text-mixer: in goes your text, set parameters to have output match <scapegoat> (or just pick "standard_Neanderthal_3"), out comes text conveying the message you wrote, in the style of your choosing.

Of course that would also strip the attributes that made it your creation.

RetroTechie··on Against Usefulness
I read that as "ignore utility in the near future". Just play around with ideas & see where it leads you. Look out waaayy further on the horizon / out of the box.

Probably with the idea that if it's radical enough & you give it time, something might come out @ some point.

RetroTechie··on The 3-degree limit could be exceeded as early as 2050
To add: ratio of surface area (skin, sweating/cooling), versus volume/weight (muscle activity, biochemical processes etc).

The bigger the animal, the harder it is to keep cool.

RetroTechie··on The 3-degree limit could be exceeded as early as 2050
The tragedy: by the time a big enough % of the public finds their own lives in turmoil, panic breaks out, politics shift, Big Oil & co get shoved aside, chances are tipping points have passed & we're in for the ride no matter what. These processes have a decades-delayed fuse.

So it may just be too little, too late, with our species' extinction on the table (never mind all the 1000s of species we've already wiped out).

Don't get me wrong: every little bit helps (especially now), and sooner = better. So please keep deploying solutions, and stop contributing to the problem!

But I can't say I'm optimistic. Public at large does not understand how quickly the state of a system can change once underlying factors cross critical thresholds.

RetroTechie··on Jurassic Park computers in excruciating detail
> That kind of scaling and software inertia is just too hard to compete against.

What stopped SGI from offering such $199 add-on cards, but with their name on it?

RetroTechie··on Library Catalog (Card Catalog)
For the youngsters on here: how one found items in dead-tree libraries before computers came around. These are called a "card catalog". They were familiar objects for generations of people worldwide.

I searched the web but picked the Wikipedia page as one of the best resources on the subject. Some other pages you might enjoy:

Library of Congress - How to use the card catalog https://guides.loc.gov/card-catalog/using-the-card-catalog Developer of an early, widely used computer standard https://en.wikipedia.org/wiki/Henriette_Avram https://www.allpurposeguru.com/2013/10/card-catalog-birth-an...

RetroTechie··on Your 'app' could have been a webpage (so I fixed it for you)
"Terminal" will do. These were text user interface (TUI) based browsers accessing a remote database, before web browsers appeared (or even the web itself). Fixed, very limited feature set, talking to database over plain LAN, a dedicated phone line or similar.

Possibly not even that: just a dumb terminal sending keystrokes & displaying text returned by the server.

Setups like this have been around almost as long as computers exist.

I recall that these replaced library catalogs in the form of drawers full of cards. Each card representing a book located elsewhere in the library (or available upon request from a central location). Man I'm old...

RetroTechie··on Your 'app' could have been a webpage (so I fixed it for you)
People are on <insert social network here> because their family & friends are. Once on, it's hard to un-glue because it keeps zucking you in.
RetroTechie··on Your 'app' could have been a webpage (so I fixed it for you)
Sounds like what could be a useful built-in OS feature. Along the lines of:

"Aim camera at QR code to put "open-link" icon on your home screen"

Does something like that not exist?

RetroTechie··on The Future Worth Building Is Human
Reads as a well-written mission statement. With nice references that elaborate on some issues.

That said: safety. To prevent harm to who, by AI model doing what?

I can understand that in the context of a cookie-cutter model intended for consumption by a broad audience. With vendor (potentially) on the hook when it's abused for nefarious or illegal uses.

But in the context of AI models reshaped, fine-tuned and adapted according to end-users' wishes, what does "safety" even mean?

Prevent neighbours' kids from seeing images that are only generated & viewed in the privacy of one's home? To prevent AI model from wasting the $ on user's bank account? (people have let AI models do that). Give bad health advice? Who's the judge on "good" and "bad" there?

If the core architecture provides "safety" (however defined), that's policy built-in, right? (opposed to mission statement). If "safety" is just configuration & finetuning, that's in the user's hands, right?

RetroTechie··on The Future Worth Building Is Human
Define "better".
RetroTechie··on The kids with phones are alright
> Smartphones are fomes peccati.

Smartphones aren't, some apps on them are.

(besides being unneeded or a nuisance in some situations)

RetroTechie··on Coding agents think ahead of time
+1. Inputs, processing & memory do the job.

I suspect exact and/or universal definitions for intelligence, self-awareness, 'feelings' etc will prove to be elusive, and best we'll get is systems/robots etc behaving as if possessing those qualities. With some tests to put a number on them.

Downside is that may apply to us humans too.

RetroTechie··on Proof of care in the age of AI
> The reality is people don't always care if a human poured their heart and soul into something.

The reverse: sometimes people care if you do. "Caring" and "effort" tend to be good indicators.

But imagine there's some yet-undiscovered <something> that has big implications, and conditions exist for its discovery. Then someone stumbles across it, puts out a hasty tweet, walks off & doesn't look back. Took no effort whatsoever, didn't care much about it. Or maybe some AI does that.

Would that reduce the value of the message? Imho: no.

I'm hoping we'll find ways to separate the gems from mountains of slop they're buried in, that don't require AI-powered tools to wade through that slop & pick the gems. Or establish incentives to not produce all that slop in the 1st place. Not sure if that's doable or how.

But I don't care that much about AI-generated or not (although I'd prefer if stuff were marked as such). Useful, well-written, interesting, exactly what you needed, providing a new angle on a subject, innovative: that's where it's at.

Btw I'm all out of soapboxes. Would a potato crate do, in a pinch? Not gettin' a tattoo!
