jamesgill··on NAND-16: a computer built from 277,248 NAND gates
You could also do this out of NOR gates. The Apollo Guidance Computer was famously built almost entirely from NOR gates.
jamesgill··on Joseph Szabo’s pictures of American adolescents
In the 1970s color film/development/print cost significantly more than black and white.

Shooting in b&w was common, because it was much cheaper. But of course, he could've chosen it or aesthetic reasons.

jamesgill··on Attention is all you have
"There’s one lesson the Tetris effect teaches us: whatever you focus on long enough will end up shaping your thoughts."

Yes. And--change your thoughts, change your life: https://thinkhuman.com/change-your-thoughts-change-your-life...

jamesgill··on Instrument clusters are now paid extras in two Hyundai models
I'm old enough to remember when 'automatic transmission' was a luxury option that cost more; standard (transmission) was the default.

Auto makers are always looking for ways to differentiate, upsell, and tap demand.

jamesgill··on Dad’s Custom Atari Peripherals
A fun story, but what really grabbed me was the story he linked to about the author's father, the engineer: https://lostincyberspace.substack.com/p/son-of-a-son-of-a
jamesgill··on Omarchy – Linux that is capitalizing on AI momentum
Omarchy is not a distro, but that's not worth nitpicking about.

I have no problem with Omarchy, save one: it seems to (ironically) create a walled-in Linux environment that requires giving up a fair amount of control for a (lengthy) bespoke list of stuff.

This is mainly apparent with updates; if you install Omarchy, you have to update via Omarchy or risk some mayhem, you use DHH's separate package repo, etc. I'm simplifying, but that's the gist.

This seems to go against most of the reasons I like Linux.

jamesgill··on FDA authorizes first wearable device that monitors ketone and blood sugar levels
All closed loop systems require human action--maintenance,filling reservoirs, changing sites, dealing with the inherent variation of CGMs, estimating carbs, etc. even if glucagon delivery were on board (it's being worked on). But most are generally providing insulin delivery in real time, based on CGM data.

Also, I agree--glucagon would be a useful thing onboard for T1d, but not really for T2d, because (as you know) the essential problem there is highs, not lows.

And I definitely agree about CGM accuracy: most people don't know that there's a significant margin of error in all CGMs. It's 'close', but not precise.

I'm a parent of a T1d kid.

jamesgill··on FDA authorizes first wearable device that monitors ketone and blood sugar levels
Automated glucose control is already available via wearable insulin pumps combined with CGMs in a 'closed loop' system.
jamesgill··on Early Humans Likely Ate Carbs and Sugary Foods
Humans have always eaten carbs; it’s the body’s preferred energy source. But human bodies can get energy from three sources, in order of preference—carbs, fat, and muscle (when all else fails).

Our bodies evolved to store fat for this very reason—future energy needs. Ancient humans lived feast or famine, and our biology adapted. We’re built to fast for days, using body fat for energy. When carbs are available, they’re preferred because they are faster and easier to burn.

Sugar is carbs. But ancient fruit in no way resembles today’s cultivated monstrosities, in appearance or sugar content.

Our modern problem is—we gorge on carbs all day long. So our body helpfully stores the excess as body fat for future use—because it expects eventual ‘famine’ where we’ll be fasting with few carbs available and need it. But we never let our body get to burn that fat.

jamesgill··on Abdominal fat predicts heart disease risk better than BMI
A nitpick about the title: Not strictly abdominal fat, but visceral abdominal fat, which surrounds the organs. Not all abdominal fat is visceral; in fact, in many people the majority is not. The article mentions visceral early on, which is the subject.
jamesgill··on GNU Hurd News 2026-Q2
I’ve recently taken to calling it GNU minus Linux.
jamesgill··on The End of an Era
Hugh gets one thing right: his success was luck and timing. He self-published a modest story at an opportune time for cheap, and the easy accessibility of Kindle books for pennies made him enough success to quit his day job.

"Pulp" fiction has always been a very hard way to make a living, and nearly everyone has failed at doing so. Centuries before AI.

Now, if people leverage AI to write magnitudes more mediocre pulp fiction, what will happen? I have a guess:

1. millions of ebooks drive prices down to almost free (or just free).

2. quality eventually gets worse.

3. Consumers perceive it as lower and lower value. A commodity at best.

4. Distributors like Amazon eventually cut out the 'producer' and simply manufacture it themselves.

Spoiler: this is already happening.

And interestingly, most of these were predicted at the advent of the "self-publish to Amazon" era 10-15 years ago.

jamesgill··on Every new car sold in the European Union must include a driver monitoring camera
I found this useful: https://seeingmachines.com/understanding-advanced-driver-dis...

From that article:

"Like DDAW systems, ADDW systems must function without the use of biometric information, including facial recognition, of any vehicle occupants. It must also operate within a closed-loop system, only recording and retaining data on the device that is necessary for the system to function."

jamesgill··on Show HN: Homebrew 6.0.0
I know this runs on Linux too. As a Linux user, I'm unclear on why I might use this instead of apt or dnf, for example. Any Linux users out there have experience with both Homebrew and one of these?
jamesgill··on Apple reveals new AI architecture built around Google Gemini models
Maybe I'm wrong, but this seems to strongly undercut Apple's claims about privacy.
jamesgill··on HP re-releases classic computer science calculator: The HP-16C
Because I'm such a longtime fan of HP models.
jamesgill··on HP re-releases classic computer science calculator: The HP-16C
I'm a lifelong fan of HP calculators. I have a 15c in front of me right now that I've had since the mid-ish 80s. Still works perfectly.

But the 15c 'Collector's Edition' had some issues, and I wonder about the build quality and reliability of this new one, too. Plus: my guess is you can get an original working 16c on eBay for less than this is going to cost.

Honestly, it pains me to say it but I'd recommend a SwissMicros DM16L instead: https://www.swissmicros.com/product/dm16l

jamesgill··on Shift from a leader-follower to a leader-leader approach
It's not a framework, and it requires no diagram. It's just trusting and empowering people to do the job, then getting out of their way. People tend to rise to your level of trust.

I wrote about this, because after a long career I've come to see that most people have no idea what leadership is, or how it works: https://thinkhuman.com/the-leader-ship/

jamesgill··on It Will Never Be the Year of the Linux Desktop
The thing is: it already is the year of the Linux Desktop for me. I don't care about 'OS market share' or how many people use something; I have no control over them.

I also don't care about "OS-maxxing", either--quibbling over 'Wayland', or which OS has the best window manager, arguing about 'gaming', etc.

What I do care about? Freedom and control. Linux gives me that.

So my desktop? It's Linux. The Year of Linux on the Desktop arrived for me years ago. And it can be that year for anyone, anytime. Today.

jamesgill··on I hated writing until I learned there’s a science to it (2024)
It's not a science. At best, there are best practices--and some of the best, most famous writing has ignored them. "Writing" is broad, means a lot of things, and defies algorithms.
jamesgill··on Ask HN: What made you lose faith in God/Religion?
Which god?
jamesgill··on Ask HN: When and why did you start believing in God?
Which god?
jamesgill··on California moves to exempt Linux from its age-verification law after backlash
Linux was always exempt--because it's not an operating system.
jamesgill··on Iowa to mandate students take Intellectual Freedom classes amid low enrollment
At first, I thought the saddest part was:

"The nonprofit Common Sense Institute reported student interest and enrollment was low — with just eight students in one class. The report said enrollment is unlikely to grow unless the state mandated students take the classes, which is exactly what Republican lawmakers passed."

But despite the overtly Orwellian effort, the Democrats responded in typical ineffectual, tone-deaf fashion:

"Democratic Sen. Janet Petersen slammed that idea, arguing it will drive up costs for Iowa college students and their families."

Costs. Yeah. That's the problem.

jamesgill··on It's Not a Mystery Why Fertility Rates Are Declining
‘Fertility’ is one of those misleading terms that sounds like it means one thing (capability) when it really means another (output).

TL;DR: People aren’t unable to have more children; they’re just choosing not to.

jamesgill··on An Apple (II) for Teacher
"His [Wozniak's] subsequent ventures, including a stint teaching computer skills to students in the Los Gatos School District, were marked by amiability and good nature, not a will to technological power."

Woz is the kind of nerd I always aspired to be.

jamesgill··on Meta to cut 8000 employees despite $26B Q1 net income
Americans will never quite understand what they bargained away for a government and culture based on freewheeling capitalism and a vague notion of ‘freedom’ that seems to absolve everyone of the one thing real freedom requires: responsibility.
jamesgill··on Intel's comeback story is even wilder than it seems
I wouldn’t call it a “comeback”. By making some desperate ‘deals’ and the new CEO pulling the company hard to the right, they’ve bought some time to delay the inevitable.

But Intel’s time as anything more than a manufacturing contractor are over.

jamesgill··on US and Iran agree to provisional ceasefire
Congratulations for rediscovering Machiavelli. “The ends justify the means” is such a winning philosophy.
jamesgill··on Trump fires Pam Bondi as attorney general
I forgot: the Curb-to-Bus (CtB) transit time is measured in Scaramuccis.
