PorterDuff··on A Pixel Is Not A Little Square (1995) [pdf]
Heck, if you've written color film recorder software, they're not even particularly square
PorterDuff··on US proposes barring tech companies from offering financial services
How would you deal with antitrust?
PorterDuff··on The Graphics Chip Chronicles
82786 was a strange part. I programmed it for one product. As I remember it was mostly set up for windowing with a handful of primitives and not really worth the trouble. We probably should have used an ASIC.

Also used the 34010 and 34020.

I do remember the fuss when VGA came out. The hardware guys took apart one of each of the PS2s. Nobody cared about microchannel some interest in VGA.

PorterDuff··on An exoplanet has been found in the ‘Neptunian Desert’
I decided to declare a jihad on downvotes. In some ways, this site is as bad as reddit with the children and their 'vote' concept. Every downvoted comment gets an upvote from me, it doesn't matter what they say.
PorterDuff··on An exoplanet has been found in the ‘Neptunian Desert’
I'd have to look it up, but perhaps getting smacked by an outer planet (to make the moon) delivered a lot of the atmosphere's contents.
PorterDuff··on An exoplanet has been found in the ‘Neptunian Desert’
lol. Say what? I get downvoted for wondering what a large planet with an atmosphere that's close to it's star has for weather?
PorterDuff··on NASA executive quits weeks after appointment to lead 2024 moon landing plan
Au contraire. Just scatter around the components of the project into various Congressional districts. Build large facilities in places with political horsepower and name them after important people. Gemini/Apollo is fraught with this.

Personally, I doubt that the science community would be behind manned space travel in any case. It's more marketed to the engineering and military world. I wouldn't doubt that internal NASA competition over limited dollars shows astronomers and planet scientists smothering the manned efforts in it's crib now and again.

Imagine what the weather is like.
PorterDuff··on Amazon defeated Rekognition shareholder revolt by a large margin
Dunno why you are downvoted (I assume that's what greyed text means, if not, mea culpa), but that's the world we live in I guess.

I'd say that the more general problem is that we all had privacy at one time due to the difficulties in gathering/parsing/storing. People used to be able to expect that their criminal record was somewhat private, that private conversations in public places were private, that their locations were private. 'Forgotten' can be interchanged for 'private' in these cases.

There was no real protection in terms of law, just in terms of practicality.

The great irony of modern times is that the sea change was schlepped in with the market for advertising, not your local Stasi. Of course, the cops are happy to use it if it exists.

PorterDuff··on Adventures with ffmpeg and color ranges
At the risk of telling you something you know, there's a lot more things to trip on with proper color space conversion than just going from scaled to full range color in 601. It's something of rat's nest to cover all the cases.
PorterDuff··on Tell HN: Work at a Startup Expo will be at YC on Saturday, June 29
I think that's a great idea, it's cool to see someone slice and dice the problem a different way. An alternative would be a remote work variant.

Being an old fart, I've spent 100% of my career working for (or consulting for) companies that actually made and sold physical products. I wonder if you couldn't have a job fair for startups of that type. I suppose that having an embedded systems startup expo or small manufacturers expo might be too specialized, but it would be a neat thing.

PorterDuff··on Scene report from the Chernobyl Zone
I thought it was German soldiers who spoke British. It's a crazy old world.
PorterDuff··on Blackbird SR-71 Flight Manual (2010)
Just to throw my one cent in on these matters.

PorterDuff··on NASA executive quits weeks after appointment to lead 2024 moon landing plan
It seems to me that space proponents need to study other tricky-to-justify programs for lessons. Just do whatever the F-35 people did.

I wish that the main thrust (so to speak) was towards permanent off-planet settlement and economies rather than merely having a human grab the soil samples.

Also, it would be nice to see a more results-oriented attitude rather than have the whole deal watered down with politics. Of course, you could probably say that about the US military.

PorterDuff··on Bill to put health warnings on soda and sugary drinks advances in California
Maybe they need to be like Australian cigarettes. You could have a picture of someone who doesn't need the extra calories.
PorterDuff··on H.264 is magic (2016)
Thinking back on the different dead ends, I figure that H.264 is just a reasonable evolutionary stage.

Now, Pixelon...that was probably magic.

PorterDuff··on After 15 Years, the Pirate Bay Still Can’t Be Killed
It's funny how quantity has a lack of quality all it's own.

My own take for getting surprised is to check out (usually) European jazz radio stations on internet radio.

PorterDuff··on After 15 Years, the Pirate Bay Still Can’t Be Killed
That's what I do. It's absolutely stellar that there are so many live concerts, old TV shows, etc. of things that I'm interested in. Maybe if you have interests outside of the mainstream it's safe for now, but sometimes I wonder if I shouldn't download absolutely everything I like in order to avoid a future where more copyright detectin' software and lawyers get involved.

Another angle that's nice about youtube are all the digitized LPs. An awful lot of music never made the jump to CD, I remember how huge the jazz album bins used to be at some record stores.

PorterDuff··on Apple removes game after Chinese company cloned, trademarked, requested takedown
I suppose that the worst case scenario is that the bond market gets involved. Ugly.

OTOH, maybe it's better to have a small conflict early rather than a large one later.

PorterDuff··on Assange Indicted Under Espionage Act, Raising First Amendment Issues
Although I don't pretend to understand the specifics, I expect that any charges against him will be on the corner cases. They won't be a frontal assault on Wikileaks. After all, what's the difference between WL and the New York Times when you get right down to it?

My guess is that hidden on page 1050 (or whatever) of the charges, the meat of the matter will be some sort of Swiss Army knife of Justice Department power involving a kind of conspiracy, meeting with C. Manning, or whatever. Truth is, they can put anyone in prison any time they like.

Thank goodness the intelligence nomenklatura in this country isn't joined at the hip with the Googles, Facebooks, and AT&Ts of the world. Then where would we be?

PorterDuff··on Japan Begins Experiment of Opening to Immigration
So what happens when you have perpetual growth?
PorterDuff··on This Old House: The Rare Home-Improvement Show That Spotlights Skilled Workers
I find myself only watching the cars shows that are pure amateur affairs.

The instant that there's money involved (or Motortrend TV) it gets awful. I could give a rip about some pro shop putting together a $200k Camaro in about 22 minutes...usually artificial deadlines and all.

PorterDuff··on Interactive exploration of earnings by age and industry (2018)
Hang on, was there anything in those charts about how many people actually make it to 65 in those professions? Maybe I just missed it.
PorterDuff··on ‘Earthworm Dilemma’ Has Climate Scientists Racing to Keep Up
What happens when you have 15 billion people eating a non-meat diet?
PorterDuff··on “It’s hard to take risks if you don’t have a safety net”
The original twitter post, twitter responses, and responses here made me muse about how the definition of 'start-up' has changed in the last few decades. Ennui ensued.
PorterDuff··on A Sealed Garden That Was Watered Once in 53 Years (2017)
On the restarting, I completely agree. You'd need to restart the whole thing multiple times as your knowledge increased. Maybe somebody else is doing large scale closed system human habitats, but I haven't heard of any.

edit: A bit of googling led me to the Russian one and some books on the problem generally. It sounds like a great speciality but probably hard to get a gig in.

If I had a multi-decade old terrarium, I'd be darn tempted to think of sensors you could stick in there and see if there's some sort of cycle going on.

PorterDuff··on Three geeks rescue a 50-year-old IBM 360 mainframe from an abandoned building
You can argue that the real serious time is spent on the peripherals in order to read old media. I haven't seen a full list of formats for both computers and video tape (plus cards, paper tape, etc) but it has to be pretty big.
PorterDuff··on Three geeks rescue a 50-year-old IBM 360 mainframe from an abandoned building
I wonder if the main problem isn't the generational handover of the hobbyist's collection and knowledge. It probably isn't that hard to find someone who'll geek out on old pinball machines, radios, Linotype machines, cars, big honkin' mills and lathes, partly because they remember them when they were younger so there was a strong impression made. Domain knowledge can be ferreted out from some still-living people.

I was thinking about that while watching this guy and his 11 buildings of stuff:

PorterDuff··on Google's Civil War
I guess that's possible although I have no interaction with kids in their 20s and early 30s at those companies. I can't remember any political interests when I was that age aside from the odd scattering of typical programmer libertarianism, a natural side effect of living in a bubble.

What I find amusing is all the fuss at these companies, perhaps about real problems perhaps not, while those same employees are all busily laying brickwork for a kind of permanent surveillance state. Given the leviathan they are building, you'd think they'd just bug the cafeteria and everyones cubicle in order to catch evil doers.

PorterDuff··on Preventing the Collapse of Civilization [video]
I had a few cocktails and thought about a few points made in the video.

It seems to me that there are two different notions here that are being conflated:

. A rotting of knowledge over time.

. A variant of Moore's Law. In this case, the idea that the value of technology, in a particular area, has a decreasing value on the margin.

It's kind of like the notions you see in cliodynamics, that there are a few interacting sine waves (or some other function) in mass human behavior.

I suppose that the main concept of importance is how it all might mess with your own personal situation. Personally, I think that the West is in decline, but that doesn't have a whole lot to do with the quality of software on internet websites.
